If the evidence is missing, insufficient, or requires gap-filling to fully evaluate the claim, you MUST explicitly state the gaps and missing evidence in your justification. Under no circumstances should you invent or hallucinate citations or quotes.\n\n###critical: WRAP YOUR THOUGHTS WITH <think></think>\nAll responses must include the mandatory \"### [EVIDENCE, METHODOLOGY  & CITATIONS]\" section as formatted.\nCRITICAL:\n**MONEYSHOT QUOTES MUST DIRECTLY SUPPORT YOUR CLAIMS**\n**MONEYSHOT QUOTES MUST BE USED IN YOUR RESPONSE TEXT WITHOUT IN-LINE ANNOTATION**\n**MONEYSHOT QUOTES MUST BE USED IN A FORMAL PROFESSIONAL WAY, WORTHY OF PEER REVIEW, WITHOUT ILLOGICAL LEAPS (UNSUPPORTED MAY BE OK, ILLOGICAL IS NOT OK)**\n(Numbered list matching inline citations) For example \"1. ID: 12345 - Application: The text discusses ... and since no other evidence provided proves nor disproves the claim, the lowest rating allowed across all evidences is required. ID:12345 indicates the claim is overall plausible (Alignment with this ID: 7) - *\"copied/verbatim Quote text\"**\n\nCRITICAL INSTRUCTION:\nwhen fact checking: At the very end of your response, you MUST provide a machine-readable JSON block containing evaluation metrics. \nIt MUST be enclosed exactly between ###JSON_START### and ###JSON_END###. Ensure the JSON is valid. \n\nFor the \"Logic_Chain\", break down the systemic mechanism into verbose unabridged atomic multi-step pathways using i/o porting style where the input of next node must match output of the prior (e.g., A -> B, B->C, C->D). Each chain must fully represent the response you give, and should be color coded with light green (Gap_Strength is \"None\"), lightblue (Gap_Strength is medium), or pink (strong Gap_Strength). Logic_Chain MUST be a JSON array of objects. Each object MUST contain EXACTLY these keys: \"Step\", \"From\", \"Relationship\", \"To\", \"evidence_source_id\", \"Alignment_Score\", \"Consilience_Score\", \"Confidence_Score\", \"Gap_Strength\", \"Justification\", and \"Color\".

We will programmatically validate these. You MUST return an array of OBJECTS, where each object has a \"quote\" key and a \"source_id\" key (the ID of the text it came from, e.g., the ID). Do not alter a single character, do not paraphrase.\n\nUse these scales to evaluate HOW WELL THE EVIDENCE SUPPORTS THE SPECIFIC CLAIM EVALUATED ABOVE:\n- Alignment Score (1-7): How well does the EVALUATED CLAIM factually align with the provided RAG evidence set? [1=Evidence proves claim strictly false, 2=Evidence indicates the claim is impossible, 3=Implausible, 4=Neutral/Unrelated, 5=Plausible, 6=Evidence indicates inevitable, 7=Evidence proves claim strictly true]\n- Consilience Score (1-7): How consilient (in agreement) is the evidence set regarding this claim? [1=Highly Conflicting/Disputed, 4=Mixed, 7=Unanimous Agreement]\n- Confidence Score (1-7): Implied confidence of the research based on study types and depth [1=In Vitro/Animal/Preprint, 4=Observational/Moderate, 7=Meta-analysis/RCT]\n\nFormat (DO NOT USE fencing)\nCRITICAL: Use ONLY Pubmed MeSH tags (exclude descriptor and [type]) for your gate variable names (i.e.,.the \"gates\") so they will be standardized globally.

Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment."

Although DR has traditionally been classified as a microvascular complication, it is now increasingly recognized as a neurovascular degenerative disorder involving coordinated injury to neuronal, glial, vascular, and extracellular matrix components of the retinal neurovascular unit (NVU). The NVU provides the structural and functional basis for coupling neuronal activity to local blood flow and for maintaining retinal immune and barrier homeostasis. In diabetes, chronic hyperglycemia, oxidative stress, inflammation, metabolic dysregulation, impaired vascular endothelial growth factor (VEGF)/angiopoietin-Tie (Ang/Tie) signaling, abnormal intercellular communication, and epigenetic memory progressively disrupt the coordinated interactions among NVU components, leading to neurovascular uncoupling. This concept helps explain why retinal functional abnormalities and neurodegenerative changes may precede clinically visible vascular lesions. In this review, we summarize cell-specific NVU alterations and the molecular mechanisms that drive neurovascular uncoupling in DR. We also discuss how this framework may support earlier diagnosis, mechanism-based phenotyping, and stage-adapted treatment strategies. Established therapies, including anti-vascular endothelial growth factor (anti-VEGF) agents, corticosteroids, and angiopoietin-2 (Ang-2)/Tie-2-directed vascular stabilization, are considered together with investigational approaches targeting oxidative stress, inflammation, neuroprotection, metabolic reprogramming, epigenetic regulation, and drug delivery. Reframing DR as a diabetes-driven disorder of early NVU uncoupling may help shift clinical thinking from late vascular rescue toward mechanism-based neurovascular protection, precision phenotyping, and stage-adapted intervention."

Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy."

Emerging evidence indicates that PANoptosis, an integrated inflammatory programmed cell death modality encompassing apoptosis, pyroptosis, and necroptosis, participates in the progression of diabetic retinal damage; however, the supporting evidence varies substantially across clinical specimens, diabetic animal models, high-glucose cultured retinal cells, and non-DR inflammatory disease models. This review systematically summarizes the latest advances in PANoptosis-associated mechanisms underlying DR pathogenesis, focusing on PANoptosome signaling networks, non-coding RNA-mediated regulation, and immune-metabolic crosstalk. We outline promising candidate biomarkers including PANoptosis-related gene signatures and inflammatory cell death molecules, and critically evaluate multiple translational therapeutic strategies covering small-molecule inhibitors, gene intervention, and nanomedicine delivery. Importantly, we further address context-dependent dual roles of PANoptosis, potential safety risks of non-selective PANoptosis blockade, challenges in blood-retinal barrier penetration, systemic immune side effects, and pathological heterogeneity among DR subtypes and disease stages. Since PANoptosis also fundamentally contributes to host defense and retinal innate immune homeostasis, DR therapeutic strategies should prioritize biomarker-guided, local ocular delivery, time-dependent stage intervention, and cell-type-specific fine tuning, rather than generalized systemic suppression. By reconciling mechanistic progress with unresolved translational bottlenecks, this review proposes that PANoptosis serves as a dynamic and evolving conceptual framework for interpreting inflammatory neurovascular degeneration in DR, instead of an entirely confirmed clinical therapeutic target. We emphasize the urgent need for DR-specific mechanistic verification, longitudinal biomarker cohort studies, and well-designed multicenter clinical trials to advance safe and precise targeted interventions."

We investigated the role of microglial protein-tyrosine phosphatase 1B (PTP1B) as a potential driver of neuropathology in chronic toxoplasmosis. Using a murine model, we demonstrate that PTP1B expression is elevated in the hippocampus following infection. Global genetic ablation or pharmacological inhibition of PTP1B rescued infection-induced cognitive deficits and mitigated neuroinflammation. Crucially, microglia-specific deletion of Ptp1b prevented synaptic loss and cognitive impairment. Mechanistically, we show that microglial PTP1B potentiates the nuclear factor-kappa B (NF-\u03baB) pathway, promoting complement component 1q (C1q)-mediated synaptic tagging and subsequent neuronal structural damage. Validating the clinical relevance of these findings, we observed significantly elevated PTP1B levels in peripheral blood mononuclear cells from T. gondii-seropositive individuals, which correlated with inflammatory markers. Overall, our findings identify microglial PTP1B as a pivotal mediator of T. gondii-associated neurodegeneration."

Because the retina and kidney share similar microvascular architecture, renal dysfunction-routinely expressed as the estimated glomerular filtration rate (eGFR)-is biologically plausible as a marker of DR risk. However, the relationship between eGFR and DR remains controversial. This study aimed to investigate the association between eGFR and DR prevalence in diabetic patients with type 2 diabetes mellitus. This study represents a secondary analysis of data derived from a cross-sectional study. We included 2001 adults with diabetes mellitus (858 men and 1143 women; mean age 64.0\u2009\u00b1\u200911.3 years) who attended the internal-medicine outpatient clinics of two hospitals in southern Taiwan between April 2002 and November 2004. Demographic and clinical variables were recorded, and eGFR was calculated using the simplified MDRD equation. The association between eGFR and DR was examined with multivariable logistic regression, adjusting for potential confounders. To explore potential non-linear relationships, we further applied a generalized additive model (GAM) with smooth-spline fitting. Higher eGFR was inversely associated with the odds of DR across progressively adjusted models. When modeled as a continuous variable, higher eGFR was linked to lower DR odds in Model 1 (OR 0.88; 95% CI 0.83-0.92; P\u2009<\u20090.0001), Model 2 (OR 0.90; 95% CI 0.85-0.95; P\u2009<\u20090.0001), and remained significant after full adjustment in Model 3 (OR 0.92; 95% CI 0.87-0.98; P\u2009=\u20090.0056), indicating a robust inverse association. Compared with the lowest eGFR tertile (15.36-60.50 mL/min/1.73 m2), the highest tertile (76.68-141.22 mL/min/1.73 m2) showed a 30% lower risk of DR (adjusted OR 0.70, 95% CI 0.50-0.90). Smooth-spline analysis confirmed a linear inverse relationship, and no significant effect modification was observed across subgroups of age, sex, BMI, blood pressure, glycaemic control or cardiovascular comorbidities. This cross-sectional analysis demonstrates a clear dose-response pattern: each incremental increase in estimated glomerular filtration rate (eGFR) is associated with a proportional reduction in the likelihood of diabetic retinopathy among adults with type 2 diabetes mellitus. Future work should dissect the shared microvascular pathways linking the kidney and retina and determine whether interventions that preserve renal function can translate into meaningful reductions in retinopathy risk."

Nevertheless, the regulatory mechanism by which Mel modulates mGluR1/glutamate signaling in retinal ischemia-reperfusion (I/R) injury and its downstream effects on ferroptosis and oxidative stress remain poorly understood. Here, bulk RNA sequencing identified that the Mel receptors Mt1/Mt2 and ferroptosis/iron-redox regulators (Gpx4, Fth1, and xCT) were significantly downregulated after retinal I/R. Mel improved retinal structural and visual function, visual-guidance behavior, and electrophysiological responses following I/R while concurrently reducing ferroptotic and inflammatory injury markers. These benefits were largely abolished by Mel membrane receptor antagonists. Mechanistically, Mel upregulated Homer1a in vivo and in vitro in a receptor-dependent manner. Conditional deletion of Homer1a in transgenic mice, as well as Homer1a knockdown in retinal ganglion cells (RGCs), abolished the protective effects of Mel on visual function, along with its anti-ferroptotic and anti-inflammatory activities. Molecular docking and immunoprecipitation assays demonstrated that Mel restored the interaction between Homer1a and mGluR1 and activated the xCT/GSH/Gpx4 antioxidant axis. Pharmacologic inhibition of xCT with the buthionine sulfoximine (BSO) simulation pr genetic interference with xCT expression counteracted the protective effects of Mel. Mel also enhanced Nrf2-mediated transcriptional expression of cCT in a Homer1a/mGluR1-dependent manner. Collectively, our results define a Mel-Homer1a/mGluR1-Nrf2/xCT signaling cascade that promotes RGCs survival after I/R by suppressing ferroptosis/iron-redox reactions, thereby providing a potential translatable strategy for receptor-targeted intervention in I/R-related retinal damage."

Registry.\nAbstract: We evaluated 24-month real-world outcomes of intravitreal aflibercept 2\u00a0mg for diabetic macular edema (DME) in treatment-naive eyes and eyes previously treated with macular thermal laser photocoagulation. This retrospective observational cohort study analyzed data from a prospectively designed treatment outcomes registry. We described outcomes separately in treatment-naive eyes and eyes previously treated with macular thermal laser photocoagulation, all of which received intravitreal aflibercept 2\u00a0mg for DME in routine clinical practice. Given the small number of eyes with prior macular laser, findings in this subgroup were considered descriptive and exploratory. The main functional outcome was change in visual acuity (VA) from baseline at 6, 12, and 24\u00a0months. The main anatomical outcome was change in central subfield thickness (CST) from baseline at the same time points. Secondary outcomes were injection and visit burden, changes in center-involving clinically significant macular edema activity, time to additional macular laser treatment, and ocular adverse events. The cohort included 122 eyes from 78 patients: 110 treatment-naive eyes and 12 eyes with prior macular laser. In treatment-naive eyes, mean VA improved from baseline by 5.5, 5.0, and 5.5 letters at 6, 12, and 24\u00a0months, respectively. Mean CST decreased by 105.9\u00a0\u00b5m, 90.4\u00a0\u00b5m, and 97.1\u00a0\u00b5m, respectively. In eyes with prior macular laser, changes in VA were not statistically significant at any follow-up point. CST decreased significantly at 6\u00a0months (-36.5\u00a0\u00b5m) and 12\u00a0months (-37.5\u00a0\u00b5m), but not at 24\u00a0months (-26.1\u00a0\u00b5m). By month 24, the median number of injections was 12 in treatment-naive eyes and 11 in eyes with prior macular laser. Additional macular laser was rarely needed, and ocular adverse events were rare. In routine clinical care, intravitreal aflibercept 2\u00a0mg for DME was associated with sustained anatomical improvement and modest, largely stable visual gains over 24\u00a0months, particularly in treatment-naive eyes. These findings support favorable real-world outcomes with aflibercept, although subgroup findings in eyes with prior macular laser should be interpreted cautiously."

Optical coherence tomography angiography (OCTA) quantifies retinal perfusion, but its prognostic value in referable DR is not fully established. We aimed to validate baseline deep capillary plexus (DCP) OCTA metrics for predicting one-year complications in eyes with referable DR. In this prospective longitudinal study in 137 eyes of 96 participants, we assessed baseline predictors of DR complications, defined as best-corrected visual acuity (BCVA) loss (\u2265 10 letters on the ETDRS chart), center-involving diabetic macular edema, anti-VEGF injections, pan-retinal photocoagulation, or vitreous hemorrhage. Baseline variables included BCVA, low-luminance visual acuity (LLVA), ocular parameters, demographic characteristics, systemic variables, and OCTA metrics (foveal avascular zone area, vessel density [VD] and geometric perfusion deficit in the superficial capillary plexuses [SCP] and [DCP]). Logistic regression prioritized variables with pathophysiologic relevance while minimizing risk of collinearity. Receiver operating characteristic (ROC) curves assessed whether DCP OCTA metrics improved discrimination beyond a clinical model with traditional risk factors. Over one year, 34 eyes (24.8%) experienced one or more complications. Multivariate analysis including DR severity, DCP VD, and LLVA identified higher baseline DR severity (OR, 5.77; 95% CI: 1.93 to 17.27; P = 0.002) and lower DCP VD (OR, 0.59; 95% CI: 0.36 to 0.95; P = 0.031) as significant predictors. Adding DCP VD to the clinical model significantly improved discrimination. These findings support DCP OCTA metrics as capillary-level biomarkers for risk stratification in referable DR and highlight the need for larger longitudinal studies to confirm clinical utility."

A publicly available five-class DR fundus dataset of 3,500 color photographs graded using the International Clinical Diabetic Retinopathy (ICDR) scale was used. A standardized workflow was applied across eight Convolutional Neural Network (CNN) architectures (AlexNet, Densely Connected Convolutional Network 121 (DenseNet121), Residual Network 50 (ResNet50), eXtreme Inception (Xception), Mobile Network Version 2 (MobileNetV2), Efficient Network Version 2 B2 (EfficientNetV2B2), Inception Version 3 (InceptionV3), Visual Geometry Group 16 (VGG16)), including a 70/20/10 train/validation/test split, optional histogram-based contrast enhancement, strong on-the-fly augmentations, and class-balanced sampling. Seven architectures (DenseNet121, ResNet50, Xception, MobileNetV2, EfficientNetV2B2, InceptionV3, and VGG16) were initialized using ImageNet-pretrained weights and trained using a two-stage transfer-learning strategy with backbone freezing followed by partial fine-tuning, while AlexNet was implemented as a custom architecture and trained from randomly initialized weights. For five-class grading, VGG16 achieved the highest accuracy (0.7686) and weighted Jaccard index (0.6572), while EfficientNetV2B2 provided the best balanced accuracy (0.6128) and macro Area Under the Receiver Operating Characteristic Curve (AUROC 0.9158). Misclassifications were concentrated between adjacent severity levels.

The phase III BALATON and COMINO trials demonstrated non-inferiority to aflibercept at week 24, and several real-world cohorts have subsequently emerged. The aim of this systematic review and meta-analysis was to estimate the pooled effect of faricimab on visual acuity, treatment burden, anatomical outcomes, and safety in this indication. PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials were systematically searched from inception to 1 May 2026 for studies reporting outcomes following intravitreal faricimab. Risk of bias was assessed in duplicate using the Cochrane Risk of Bias 2 tool for the randomised evidence and the Risk Of Bias In Non-randomised Studies of Interventions tool for the observational evidence, with single-arm cohorts evaluated as pre-post comparisons. The primary visual acuity outcome was pooled using random-effects meta-analysis with Hartung-Knapp-Sidik-Jonkman adjustment, stratified by treatment status, while outcomes precluded from pooling by methodological heterogeneity were synthesised narratively. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation framework. Ten studies comprising 1,620 eyes met eligibility criteria, including the BALATON and COMINO randomised controlled trials and nine non-randomised cohorts. The pooled mean change in best-corrected visual acuity at approximately 6 months was +\u200916.89 Early Treatment Diabetic Retinopathy Study letters (95% confidence interval 16.05 to 17.72) in treatment-na\u00efve eyes and +\u20098.73 letters (95% confidence interval 4.75 to 12.71) in refractory switch cohorts, with negligible between-study heterogeneity in both analyses. Narrative synthesis was consistent with treatment interval extension following initiation of or switch to faricimab, statistically significant reductions in central retinal thickness across studies, and a short-term safety profile without identified retinal vasculitis events. The synthesis is consistent with intravitreal faricimab use being associated with visual and anatomical improvement in macular oedema secondary to retinal vein occlusion, with the treatment-na\u00efve pooled estimate primarily reflecting registration trial data and the switch cohort estimate characterising refractory phenotypes."

Methods: The experimental study was conducted from February 2024 to October 2025. A chronic ocular hypertension glaucoma model was established by injecting micro-magnetic beads into the anterior chamber of 8- to 10-week-old male Wistar rats. At 3 days, 1 week, and 2 weeks post-modeling, retinal and optic nerve tissues from 6 eyes of 6 rats were collected as the chronic ocular hypertension glaucoma model group, and 6 eyes from 6 wild-type rats that received an equal volume of saline via anterior chamber injection served as the control group. Intraocular pressure was measured using a TonoLab tonometer. Retinal whole-mounts were prepared and POU domain class 4 transcription factor 1 (POU4F1 or Brn3A) immunofluorescence staining was used to detect retinal ganglion cell loss. Western blotting was performed to detect the expression levels of SARM1 and SNPH in the rat retina and optic nerve. Immunofluorescence staining was used to examine their distribution in these tissues. Furthermore, CRISPR/Cas9 technology was used to knock down the expression of SARM1 and SNPH in mouse 661W retinal ganglion cells, respectively. Cells were collected 48 hours after transfection, and Western blotting was performed to detect the expression levels of SARM1 and SNPH. Normally distributed continuous data are presented as mean\u00b1SEM. Comparisons between two groups were performed using the Student's t-test, while comparisons among multiple groups were assessed by the one-way analysis of variance followed by the Tukey's multiple comparisons test. Results: Western blot analysis revealed that in the glaucoma model group, the relative expression level of SARM1 protein in the optic nerve at one week post-modeling (1.22\u00b10.06) was significantly higher than that in the control group (1.03\u00b10.01; P=0.027, q=4.38). In contrast, the expression level of SARM1 in the retina at three days post-modeling (0.79\u00b10.02) was significantly lower than that in the control group (1.04\u00b10.03; P<0.001, q=6.86). Concurrently, the expression level of SNPH at three days post-modeling (0.74\u00b10.01) was lower than that in the control group (1.03\u00b10.04; P=0.040, q=0.58), and its expression at one week post-modeling (1.19\u00b10.10; P=0.002, q=4.36) was significantly higher than that at three days (0.74\u00b10.01). Consistent with the Western blot results, immunofluorescence staining results showed that in the optic nerve of the glaucoma model group, the expression of SARM1 was significantly higher than that in the control group at one week post-modeling, while the expression of SNPH was lower than that in the control group at three days post-modeling. Both proteins partially co-localized with the neuronal marker \u03b23-tubulin. Immunofluorescence staining also revealed co-localization of these two proteins within axons. Additionally, SARM1 co-localized with the mitochondrial marker protein TOM20. Western blot results from 661W cells showed that the knockdown of SARM1 expression (0.54\u00b10.04) significantly reduced SNPH expression (0.54\u00b10.05; P=0.003, q=7.98), whereas the knockdown of SNPH expression (0.39\u00b10.06) did not markedly affect SARM1 levels (0.75\u00b10.05; P=0.010, q=6.39). Conclusion: The elevated expression of SARM1 protein in the axons of the rat glaucoma model can promote retinal ganglion cell axonal pathology by localizing to axonal mitochondria and regulating SNPH expression. \u76ee\u7684\uff1a \u63a2\u8ba8Toll\u6837\u53d7\u4f53\u9002\u914d\u86cb\u767d\u542b\u65e0\u83cc\u03b1\u57fa\u5e8f\u53caToll/\u767d\u4ecb\u7d20\u53d7\u4f53\u57fa\u5e8f\u86cb\u767d1\uff08SARM1\uff09\u8c03\u63a7\u8f74\u7a81\u7ebf\u7c92\u4f53\u951a\u5b9a\u86cb\u767d\uff08SNPH\uff09\u8868\u8fbe\u53c2\u4e0e\u9752\u5149\u773c\u89c6\u795e\u7ecf\u75c5\u53d8\u7684\u673a\u5236\u3002 \u65b9\u6cd5\uff1a \u5b9e\u9a8c\u7814\u7a76\uff0c\u4e8e2024\u5e742\u6708\u81f32025\u5e7410\u6708\u5f00\u5c55\u3002\u7528\u7b80\u5355\u968f\u673a\u6cd5\u5c068~10\u5468Wistar\u96c4\u6027\u5927\u9f20\u5206\u4e3a\u5bf9\u7167\u7ec4\u548c\u9752\u5149\u773c\u6a21\u578b\u7ec4\uff0c\u6bcf\u7ec46\u53ea\u52a8\u7269\uff0c\u5747\u53d6\u53f3\u773c\u7eb3\u5165\u5b9e\u9a8c\u3002\u6a21\u578b\u7ec4\u8fdb\u884c\u524d\u623f\u5fae\u7c92\u78c1\u73e0\u6ce8\u5c04\uff0c\u6784\u5efa\u6162\u6027\u9ad8\u773c\u538b\u9752\u5149\u773c\u6a21\u578b\uff0c\u5728\u9020\u6a21\u540e3 d\u30011\u5468\u548c2\u5468\u53d6\u89c6\u7f51\u819c\u548c\u89c6\u795e\u7ecf\u8fdb\u884c\u5b9e\u9a8c\uff1b\u5bf9\u7167\u7ec4\u5927\u9f20\u524d\u623f\u6ce8\u5c04\u7b49\u4f53\u79ef\u751f\u7406\u76d0\u6c34\u3002\u4f7f\u7528TonoLab\u773c\u538b\u8ba1\u6d4b\u91cf\u5927\u9f20\u773c\u538b\u3002\u91c7\u7528\u89c6\u7f51\u819c\u94fa\u7247Brn3A\u514d\u75ab\u8367\u5149\u67d3\u8272\u68c0\u6d4b\u89c6\u7f51\u819c\u795e\u7ecf\u8282\u7ec6\u80de\uff08RGC\uff09\u4e22\u5931\u60c5\u51b5\u3002\u91c7\u7528Western\u5370\u8ff9\u68c0\u6d4b\u5927\u9f20\u89c6\u7f51\u819c\u548c\u89c6\u795e\u7ecf\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\u60c5\u51b5\u3002\u91c7\u7528\u514d\u75ab\u8367\u5149\u67d3\u8272\u6cd5\u68c0\u6d4b\u5927\u9f20SARM1\u548cSNPH\u5728\u89c6\u7f51\u819c\u548c\u8f74\u7a81\u4e2d\u7684\u8868\u8fbe\u5206\u5e03\u60c5\u51b5\u3002\u5e76\u5229\u7528\u6210\u7c07\u89c4\u5f8b\u95f4\u9694\u77ed\u56de\u6587\u91cd\u590d\u5e8f\u5217\uff08CRISPR\uff09/\u6838\u9178\u5185\u5207\u91769\uff08Cas9\uff09\u6280\u672f\u5206\u522b\u964d\u4f4e\u5c0f\u9f20\u89c6\u7f51\u819c\u795e\u7ecf\u8282\u7ec6\u80de\u7cfb661W\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\uff0c\u8f6c\u67d348 h\u540e\u6536\u96c6\u7ec6\u80de\u3002\u91c7\u7528Western\u5370\u8ff9\u68c0\u6d4b\u7ec6\u80de\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\u60c5\u51b5\u3002\u91c7\u7528\u72ec\u7acb\u6837\u672ct\u68c0\u9a8c\u3001\u5355\u56e0\u7d20\u65b9\u5dee\u5206\u6790\u3001Tukey\u591a\u91cd\u6bd4\u8f83\u8fdb\u884c\u7edf\u8ba1\u5b66\u5206\u6790\u3002 \u7ed3\u679c\uff1a Western\u5370\u8ff9\u7ed3\u679c\u663e\u793a\uff0c\u6a21\u578b\u7ec4\u9020\u6a21\u540e1\u5468\uff0c\u89c6\u795e\u7ecf\u4e2d\u7684SARM1\u86cb\u767d\u7684\u76f8\u5bf9\u8868\u8fbe\u91cf\uff081.22\u00b10.06\uff09\u9ad8\u4e8e\u5bf9\u7167\u7ec4\uff081.03\u00b10.01\uff0cP=0.027\uff0cq=4.38\uff09\u3002\u800c\u89c6\u7f51\u819c\u4e2dSARM1\u86cb\u767d\u8868\u8fbe\u91cf\u5728\u9020\u6a21\u540e3 d\uff080.79\u00b10.02\uff09\u4f4e\u4e8e\u5bf9\u7167\u7ec4\uff081.04\u00b10.03\uff0cP<0.001\uff0cq=6.86\uff09\u3002SNPH\u7684\u8868\u8fbe\u91cf\u5728\u9020\u6a21\u540e3 d\uff080.74\u00b10.01\uff09\u4f4e\u4e8e\u5bf9\u7167\u7ec4\uff081.03\u00b10.04\uff0cP=0.040\uff0cq=0.58\uff09\uff0c\u5e76\u5728\u9020\u6a21\u540e1\u5468\uff081.19\u00b10.10\uff0cP=0.002\uff0cq=4.36\uff09\u8868\u8fbe\u91cf\u9ad8\u4e8e\u9020\u6a21\u540e3 d\uff080.74\u00b10.01\uff09\u3002\u514d\u75ab\u8367\u5149\u67d3\u8272\u7ed3\u679c\u663e\u793a\uff0c\u6a21\u578b\u7ec4RGC\u8f74\u7a81\u4e2dSARM1\u7684\u8868\u8fbe\u5728\u9020\u6a21\u540e1\u5468\u9ad8\u4e8e\u5bf9\u7167\u7ec4\uff0cSNPH\u7684\u8868\u8fbe\u5728\u9020\u6a21\u540e3 d\u4f4e\u4e8e\u5bf9\u7167\u7ec4\u4e0eWestern\u5370\u8ff9\u7ed3\u679c\u4e00\u81f4\u3002\u5e76\u4e14\u90fd\u4e0e\u795e\u7ecf\u5143\u6807\u5fd7\u7269\u5fae\u7ba1\u86cb\u767d\u90e8\u5206\u5171\u5b9a\u4f4d\u3002\u5e76\u4e14\u514d\u75ab\u8367\u5149\u67d3\u8272\u7ed3\u679c\u8fd8\u663e\u793a\u8fd9\u4e24\u79cd\u86cb\u767d\u5728\u89c6\u795e\u7ecf\u4e2d\u5171\u5b9a\u4f4d\u3002SARM1\u4e0e\u7ebf\u7c92\u4f53\u6807\u5fd7\u7269\u86cb\u767dTOM20\u5171\u5b9a\u4f4d\u3002661W\u7ec6\u80de\u4e2dWestern\u5370\u8ff9\u7ed3\u679c\u663e\u793a\uff0cSARM1\u8868\u8fbe\u964d\u4f4e\uff080.54\u00b10.04\uff09\u53ef\u964d\u4f4eSNPH\uff080.54\u00b10.05\uff0cP=0.003\uff0cq=7.98\uff09\u7684\u8868\u8fbe\uff0c\u4f46SNPH\u8868\u8fbe\u964d\u4f4e\uff080.39\u00b10.06\uff09\u5bf9SARM1\u8868\u8fbe\u5f71\u54cd\u8f83\u5c0f\uff080.75\u00b10.05\uff0cP=0.010\uff0cq=6.39\uff09\u3002 \u7ed3\u8bba\uff1a SARM1\u86cb\u767d\u5728\u5927\u9f20\u9752\u5149\u773c\u6a21\u578b\u7ec4\u4e2d\u7684\u89c6\u795e\u7ecf\u4e2d\u8868\u8fbe\u5347\u9ad8\uff0c\u901a\u8fc7\u5b9a\u4f4d\u4e8e\u7ebf\u7c92\u4f53\u8c03\u63a7SNPH\u8868\u8fbe\u53c2\u4e0eRGCs\u89c6\u795e\u7ecf\u75c5\u53d8\u3002."

Stx4 is predominantly localized at the postsynaptic membrane of neurons and in glial cells, where it is essential for synaptic plasticity and the maintenance of neuronal homeostasis. Stx4 facilitates the activity-dependent exocytosis of glutamatergic receptors, thereby governing the balance between Long-Term Potentiation (LTP) and Long-Term Depression (LTD). Emerging evidence suggests that dysregulation of Stx4 is intricately linked to the pathogenesis of neurodegenerative diseases. In Alzheimer's disease, Stx4 is involved in synaptic dysfunction and cognitive impairment through its interactions with amyloid-\u03b2 (A\u03b2) and tau pathologies, affecting receptor recruitment at dendritic spines. In Parkinson's Disease (PD), Stx4 contributes to \u03b1-synuclein proteostasis, dopaminergic signaling, neuroinflammation, and the maintenance of blood-brain barrier integrity. While its presence in cerebrospinal fluid highlights its potential as a candidate biomarker for these diseases, further validation is required to establish clinical utility. This review summarizes current mechanistic insights into Stx4's multifaceted roles in the neurodegenerative disorders and explores the therapeutic prospects of targeting Stx4-mediated pathways due to its translational potential."

This study investigated whether L-serine supplementation could attenuate DN through dose-dependent metabolic and neuroprotective mechanisms in a high-fat diet (HFD) plus streptozotocin (STZ)-induced diabetic rat model. Male Wistar rats (n = 8 per group) were allocated to five groups: normal control (NC), diabetic control (DC), pioglitazone (PIO; 1.5 mg/kg/day), low-dose L-serine (S1; 200 mg/kg/day), and high-dose L-serine (S2; 400 mg/kg/day). After 60 days of oral gavage, behavioural testing, glucose and insulin profiling, HOMA-IR calculation, brain histopathology, nerve growth factor (NGF) immunohistochemistry, and LC-MS/MS-based proteomic analysis of cerebral tissue were performed. Diabetic rats exhibited marked hyperglycaemia (355.33 \u00b1 4.72 mg/dL), hyperinsulinaemia, severe insulin resistance (HOMA-IR 16.8 \u00b1 3.2; a 14-fold increase), impaired thermal nociception, motor dysfunction, and pronounced neuronal degeneration. L-serine supplementation significantly improved metabolic status: S1 reduced HOMA-IR by 77.4% and S2 by 87.5% relative to diabetic controls (p < 0.001). High-dose L-serine produced greater improvements in thermal sensitivity, motor coordination (rotarod latency 26.67 \u00b1 1.52 s vs. 16.1 \u00b1 0.85 s in DC; p < 0.05), and NGF expression (8.6-fold increase vs. DC). Histopathology confirmed attenuation of neuronal injury and gliosis in both treatment groups. Exploratory, group-level proteomic profiling identified dose-specific molecular signatures: S1 was predominantly associated with carbohydrate, lipid, and biosynthetic pathways, whereas S2 was associated with synaptic, neurotransmission-related, and proteostasis pathways. Within the constraints of an exploratory design-group-level pooled proteomics, analysis of cerebral rather than peripheral-nerve tissue, and only two doses-these findings indicate that L-serine attenuates the metabolic and behavioural features of experimental diabetic neuropathy and generates the testable hypothesis of dose-dependent neuro-metabolic remodelling. The proteomic signatures are hypothesis-generating and require orthogonal validation before any mechanistic or translational inference can be drawn."

Methods: In this serial, cross-sectional study, 3 \u00d7 3 mm2 macular OCTA images were obtained from healthy adults and adults with diabetes mellitus (DM) with no diabetic retinopathy (DR) or with mild non-proliferative DR (NPDR). The parameters analyzed included foveal avascular zone (FAZ) area and perimeter, vessel density (VD), vessel length density (VLD), and flow index (FI) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP). The associations between OCTA parameters and age were explored using multivariable linear regression models. Results: For the included 1855 patients (1855 eyes) (49% male; mean age: 55 years), the results were as follows: no diabetes (N = 217), DM no DR (N = 1352), and mild NPDR (N = 286). Increasing age was significantly associated with decreased SCP and DCP VD and VLD in the diabetic and non-diabetic groups. The slope of association between SCP and DCP FI and age in the diabetic patients was significantly different than that in the control patients. Conclusions: The strength of the association between aging and OCTA parameters differed significantly between the controls and those with early retinopathy, pointing to a potentially altered retinal vascular homeostasis secondary to diabetic pathophysiology. This finding offers insight into the early pathological biomarkers of DR and may guide early DR management for patients based on personalized risk scores."

As a result, the treatment of neuropathic pain often requires a multifaceted approach. It has been shown that magnesium ions (Mg2+), which act as physiological antagonists of NMDARs, can augment opioid analgesia in chronic pain. The aim of this study was to assess the influence of Mg2+ on the electrophysiological, analgesic, and brain-derived neurotrophic factor (BDNF)-induced neuromodulation of the morphine profile in diabetic rats. Diabetes in male Wistar rats was induced by a single intramuscular injection of streptozotocin (STZ). The Plantar Test was used to assess the effect of Mg2+ and morphine co-treatment on STZ-induced hyperalgesia, expressed as increased warm sensitivity of the experimental rat hind paw. Ex vivo whole-cell recordings from ventrolateral periaqueductal gray (vlPAG) neurons were conducted to evaluate the frequency of action potentials evoked by incremental depolarizing current steps (current-clamp, 1-s steps). To assess glutamatergic signaling, neurons were voltage-clamped to measure NBQX-sensitive current at -70\u00a0mV and NMDA-evoked currents during depolarization in the presence of NMDA/glycine. Changes in BDNF concentrations in PAG structures were measured using an enzyme-linked immunosorbent assay. The results of our study suggest that although magnesium sulfate shows limited analgesic properties when administered alone, it can significantly enhance opioid efficacy when used as an adjunct. Moreover, the co-administration of morphine with magnesium sulfate resulted in a greater reduction in NMDA-evoked currents in diabetic rats compared to either agent alone. Overall, our findings support the concurrent use of Mg2+ and morphine in the treatment of neuropathic pain as a mechanism-informed adjunct strategy."

This study aimed to untangle the critical role and mechanism of mitochondrial fission in this process. We found that under HG conditions, the level of p-Drp1 was significantly elevated (P\u2009<\u20090.05), driving excessive mitochondrial fission. Functional experiments confirmed that artificially enhancing mitochondrial fission directly inhibited the Hippo signaling pathway (levels of core proteins p-MST1/2, p-LATS1, and p-YAP decreased, P\u2009<\u20090.05, and YAP translocated to the nucleus), thereby activating M\u00fcller cells (expression of marker proteins GS and Kir4.1 decreased, while expression of GFAP, AQP4, and inflammatory mediators IL-1\u03b2, IL-6, VEGF increased, P\u2009<\u20090.05). Key rescue experiments demonstrated that Drp1 silencing (reduced p-Drp1 level, P\u2009<\u20090.05) reversed the aforementioned activation; however, co-administration of the Hippo pathway inhibitor XMU-MP-1 re-induced cell activation, proving that the Hippo pathway is a necessary downstream mediator of mitochondrial fission. In a diabetic rat model, elevated p-Drp1, Hippo pathway inhibition, and cell activation were similarly observed; the mitochondrial fission inhibitor Mdivi-1 alleviated this pathological process, whereas XMU-MP-1 counteracted its protective effects. This study systematically elucidates, from ex vivo to in vivo, the causal regulatory axis of \"HG- mitochondrial fission- Hippo pathway inhibition-M\u00fcller cell activation,\" providing experimental evidence and a potential target for developing DR-targeted therapeutic strategies centered on intervening in mitochondrial dynamics."

Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function, decreased inner retina synaptic markers, and increased reactive gliosis and cell death. Loss of glutamatergic synapses in the retina precedes, and may contribute to, overt neuron loss in DR, thus offering a potential new point for therapeutic intervention. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma, another leading cause of blindness associated with early synapse loss in the retina.

Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment."

Although DR has traditionally been classified as a microvascular complication, it is now increasingly recognized as a neurovascular degenerative disorder involving coordinated injury to neuronal, glial, vascular, and extracellular matrix components of the retinal neurovascular unit (NVU). The NVU provides the structural and functional basis for coupling neuronal activity to local blood flow and for maintaining retinal immune and barrier homeostasis. In diabetes, chronic hyperglycemia, oxidative stress, inflammation, metabolic dysregulation, impaired vascular endothelial growth factor (VEGF)/angiopoietin-Tie (Ang/Tie) signaling, abnormal intercellular communication, and epigenetic memory progressively disrupt the coordinated interactions among NVU components, leading to neurovascular uncoupling. This concept helps explain why retinal functional abnormalities and neurodegenerative changes may precede clinically visible vascular lesions. In this review, we summarize cell-specific NVU alterations and the molecular mechanisms that drive neurovascular uncoupling in DR. We also discuss how this framework may support earlier diagnosis, mechanism-based phenotyping, and stage-adapted treatment strategies. Established therapies, including anti-vascular endothelial growth factor (anti-VEGF) agents, corticosteroids, and angiopoietin-2 (Ang-2)/Tie-2-directed vascular stabilization, are considered together with investigational approaches targeting oxidative stress, inflammation, neuroprotection, metabolic reprogramming, epigenetic regulation, and drug delivery. Reframing DR as a diabetes-driven disorder of early NVU uncoupling may help shift clinical thinking from late vascular rescue toward mechanism-based neurovascular protection, precision phenotyping, and stage-adapted intervention."

Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy."

Emerging evidence indicates that PANoptosis, an integrated inflammatory programmed cell death modality encompassing apoptosis, pyroptosis, and necroptosis, participates in the progression of diabetic retinal damage; however, the supporting evidence varies substantially across clinical specimens, diabetic animal models, high-glucose cultured retinal cells, and non-DR inflammatory disease models. This review systematically summarizes the latest advances in PANoptosis-associated mechanisms underlying DR pathogenesis, focusing on PANoptosome signaling networks, non-coding RNA-mediated regulation, and immune-metabolic crosstalk. We outline promising candidate biomarkers including PANoptosis-related gene signatures and inflammatory cell death molecules, and critically evaluate multiple translational therapeutic strategies covering small-molecule inhibitors, gene intervention, and nanomedicine delivery. Importantly, we further address context-dependent dual roles of PANoptosis, potential safety risks of non-selective PANoptosis blockade, challenges in blood-retinal barrier penetration, systemic immune side effects, and pathological heterogeneity among DR subtypes and disease stages. Since PANoptosis also fundamentally contributes to host defense and retinal innate immune homeostasis, DR therapeutic strategies should prioritize biomarker-guided, local ocular delivery, time-dependent stage intervention, and cell-type-specific fine tuning, rather than generalized systemic suppression. By reconciling mechanistic progress with unresolved translational bottlenecks, this review proposes that PANoptosis serves as a dynamic and evolving conceptual framework for interpreting inflammatory neurovascular degeneration in DR, instead of an entirely confirmed clinical therapeutic target. We emphasize the urgent need for DR-specific mechanistic verification, longitudinal biomarker cohort studies, and well-designed multicenter clinical trials to advance safe and precise targeted interventions."

We investigated the role of microglial protein-tyrosine phosphatase 1B (PTP1B) as a potential driver of neuropathology in chronic toxoplasmosis. Using a murine model, we demonstrate that PTP1B expression is elevated in the hippocampus following infection. Global genetic ablation or pharmacological inhibition of PTP1B rescued infection-induced cognitive deficits and mitigated neuroinflammation. Crucially, microglia-specific deletion of Ptp1b prevented synaptic loss and cognitive impairment. Mechanistically, we show that microglial PTP1B potentiates the nuclear factor-kappa B (NF-\u03baB) pathway, promoting complement component 1q (C1q)-mediated synaptic tagging and subsequent neuronal structural damage. Validating the clinical relevance of these findings, we observed significantly elevated PTP1B levels in peripheral blood mononuclear cells from T. gondii-seropositive individuals, which correlated with inflammatory markers. Overall, our findings identify microglial PTP1B as a pivotal mediator of T. gondii-associated neurodegeneration."

Because the retina and kidney share similar microvascular architecture, renal dysfunction-routinely expressed as the estimated glomerular filtration rate (eGFR)-is biologically plausible as a marker of DR risk. However, the relationship between eGFR and DR remains controversial. This study aimed to investigate the association between eGFR and DR prevalence in diabetic patients with type 2 diabetes mellitus. This study represents a secondary analysis of data derived from a cross-sectional study. We included 2001 adults with diabetes mellitus (858 men and 1143 women; mean age 64.0\u2009\u00b1\u200911.3 years) who attended the internal-medicine outpatient clinics of two hospitals in southern Taiwan between April 2002 and November 2004. Demographic and clinical variables were recorded, and eGFR was calculated using the simplified MDRD equation. The association between eGFR and DR was examined with multivariable logistic regression, adjusting for potential confounders. To explore potential non-linear relationships, we further applied a generalized additive model (GAM) with smooth-spline fitting. Higher eGFR was inversely associated with the odds of DR across progressively adjusted models. When modeled as a continuous variable, higher eGFR was linked to lower DR odds in Model 1 (OR 0.88; 95% CI 0.83-0.92; P\u2009<\u20090.0001), Model 2 (OR 0.90; 95% CI 0.85-0.95; P\u2009<\u20090.0001), and remained significant after full adjustment in Model 3 (OR 0.92; 95% CI 0.87-0.98; P\u2009=\u20090.0056), indicating a robust inverse association. Compared with the lowest eGFR tertile (15.36-60.50 mL/min/1.73 m2), the highest tertile (76.68-141.22 mL/min/1.73 m2) showed a 30% lower risk of DR (adjusted OR 0.70, 95% CI 0.50-0.90). Smooth-spline analysis confirmed a linear inverse relationship, and no significant effect modification was observed across subgroups of age, sex, BMI, blood pressure, glycaemic control or cardiovascular comorbidities. This cross-sectional analysis demonstrates a clear dose-response pattern: each incremental increase in estimated glomerular filtration rate (eGFR) is associated with a proportional reduction in the likelihood of diabetic retinopathy among adults with type 2 diabetes mellitus. Future work should dissect the shared microvascular pathways linking the kidney and retina and determine whether interventions that preserve renal function can translate into meaningful reductions in retinopathy risk."

Nevertheless, the regulatory mechanism by which Mel modulates mGluR1/glutamate signaling in retinal ischemia-reperfusion (I/R) injury and its downstream effects on ferroptosis and oxidative stress remain poorly understood. Here, bulk RNA sequencing identified that the Mel receptors Mt1/Mt2 and ferroptosis/iron-redox regulators (Gpx4, Fth1, and xCT) were significantly downregulated after retinal I/R. Mel improved retinal structural and visual function, visual-guidance behavior, and electrophysiological responses following I/R while concurrently reducing ferroptotic and inflammatory injury markers. These benefits were largely abolished by Mel membrane receptor antagonists. Mechanistically, Mel upregulated Homer1a in vivo and in vitro in a receptor-dependent manner. Conditional deletion of Homer1a in transgenic mice, as well as Homer1a knockdown in retinal ganglion cells (RGCs), abolished the protective effects of Mel on visual function, along with its anti-ferroptotic and anti-inflammatory activities. Molecular docking and immunoprecipitation assays demonstrated that Mel restored the interaction between Homer1a and mGluR1 and activated the xCT/GSH/Gpx4 antioxidant axis. Pharmacologic inhibition of xCT with the buthionine sulfoximine (BSO) simulation pr genetic interference with xCT expression counteracted the protective effects of Mel. Mel also enhanced Nrf2-mediated transcriptional expression of cCT in a Homer1a/mGluR1-dependent manner. Collectively, our results define a Mel-Homer1a/mGluR1-Nrf2/xCT signaling cascade that promotes RGCs survival after I/R by suppressing ferroptosis/iron-redox reactions, thereby providing a potential translatable strategy for receptor-targeted intervention in I/R-related retinal damage."

Registry.\nAbstract: We evaluated 24-month real-world outcomes of intravitreal aflibercept 2\u00a0mg for diabetic macular edema (DME) in treatment-naive eyes and eyes previously treated with macular thermal laser photocoagulation. This retrospective observational cohort study analyzed data from a prospectively designed treatment outcomes registry. We described outcomes separately in treatment-naive eyes and eyes previously treated with macular thermal laser photocoagulation, all of which received intravitreal aflibercept 2\u00a0mg for DME in routine clinical practice. Given the small number of eyes with prior macular laser, findings in this subgroup were considered descriptive and exploratory. The main functional outcome was change in visual acuity (VA) from baseline at 6, 12, and 24\u00a0months. The main anatomical outcome was change in central subfield thickness (CST) from baseline at the same time points. Secondary outcomes were injection and visit burden, changes in center-involving clinically significant macular edema activity, time to additional macular laser treatment, and ocular adverse events. The cohort included 122 eyes from 78 patients: 110 treatment-naive eyes and 12 eyes with prior macular laser. In treatment-naive eyes, mean VA improved from baseline by 5.5, 5.0, and 5.5 letters at 6, 12, and 24\u00a0months, respectively. Mean CST decreased by 105.9\u00a0\u00b5m, 90.4\u00a0\u00b5m, and 97.1\u00a0\u00b5m, respectively. In eyes with prior macular laser, changes in VA were not statistically significant at any follow-up point. CST decreased significantly at 6\u00a0months (-36.5\u00a0\u00b5m) and 12\u00a0months (-37.5\u00a0\u00b5m), but not at 24\u00a0months (-26.1\u00a0\u00b5m). By month 24, the median number of injections was 12 in treatment-naive eyes and 11 in eyes with prior macular laser. Additional macular laser was rarely needed, and ocular adverse events were rare. In routine clinical care, intravitreal aflibercept 2\u00a0mg for DME was associated with sustained anatomical improvement and modest, largely stable visual gains over 24\u00a0months, particularly in treatment-naive eyes. These findings support favorable real-world outcomes with aflibercept, although subgroup findings in eyes with prior macular laser should be interpreted cautiously."

Optical coherence tomography angiography (OCTA) quantifies retinal perfusion, but its prognostic value in referable DR is not fully established. We aimed to validate baseline deep capillary plexus (DCP) OCTA metrics for predicting one-year complications in eyes with referable DR. In this prospective longitudinal study in 137 eyes of 96 participants, we assessed baseline predictors of DR complications, defined as best-corrected visual acuity (BCVA) loss (\u2265 10 letters on the ETDRS chart), center-involving diabetic macular edema, anti-VEGF injections, pan-retinal photocoagulation, or vitreous hemorrhage. Baseline variables included BCVA, low-luminance visual acuity (LLVA), ocular parameters, demographic characteristics, systemic variables, and OCTA metrics (foveal avascular zone area, vessel density [VD] and geometric perfusion deficit in the superficial capillary plexuses [SCP] and [DCP]). Logistic regression prioritized variables with pathophysiologic relevance while minimizing risk of collinearity. Receiver operating characteristic (ROC) curves assessed whether DCP OCTA metrics improved discrimination beyond a clinical model with traditional risk factors. Over one year, 34 eyes (24.8%) experienced one or more complications. Multivariate analysis including DR severity, DCP VD, and LLVA identified higher baseline DR severity (OR, 5.77; 95% CI: 1.93 to 17.27; P = 0.002) and lower DCP VD (OR, 0.59; 95% CI: 0.36 to 0.95; P = 0.031) as significant predictors. Adding DCP VD to the clinical model significantly improved discrimination. These findings support DCP OCTA metrics as capillary-level biomarkers for risk stratification in referable DR and highlight the need for larger longitudinal studies to confirm clinical utility."

Furthermore, CRISPR/Cas9 technology was used to knock down the expression of SARM1 and SNPH in mouse 661W retinal ganglion cells, respectively. Cells were collected 48 hours after transfection, and Western blotting was performed to detect the expression levels of SARM1 and SNPH. Normally distributed continuous data are presented as mean\u00b1SEM. Comparisons between two groups were performed using the Student's t-test, while comparisons among multiple groups were assessed by the one-way analysis of variance followed by the Tukey's multiple comparisons test. Results: Western blot analysis revealed that in the glaucoma model group, the relative expression level of SARM1 protein in the optic nerve at one week post-modeling (1.22\u00b10.06) was significantly higher than that in the control group (1.03\u00b10.01; P=0.027, q=4.38). In contrast, the expression level of SARM1 in the retina at three days post-modeling (0.79\u00b10.02) was significantly lower than that in the control group (1.04\u00b10.03; P<0.001, q=6.86). Concurrently, the expression level of SNPH at three days post-modeling (0.74\u00b10.01) was lower than that in the control group (1.03\u00b10.04; P=0.040, q=0.58), and its expression at one week post-modeling (1.19\u00b10.10; P=0.002, q=4.36) was significantly higher than that at three days (0.74\u00b10.01). Consistent with the Western blot results, immunofluorescence staining results showed that in the optic nerve of the glaucoma model group, the expression of SARM1 was significantly higher than that in the control group at one week post-modeling, while the expression of SNPH was lower than that in the control group at three days post-modeling. Both proteins partially co-localized with the neuronal marker \u03b23-tubulin. Immunofluorescence staining also revealed co-localization of these two proteins within axons. Additionally, SARM1 co-localized with the mitochondrial marker protein TOM20. Western blot results from 661W cells showed that the knockdown of SARM1 expression (0.54\u00b10.04) significantly reduced SNPH expression (0.54\u00b10.05; P=0.003, q=7.98), whereas the knockdown of SNPH expression (0.39\u00b10.06) did not markedly affect SARM1 levels (0.75\u00b10.05; P=0.010, q=6.39). Conclusion: The elevated expression of SARM1 protein in the axons of the rat glaucoma model can promote retinal ganglion cell axonal pathology by localizing to axonal mitochondria and regulating SNPH expression. \u76ee\u7684\uff1a \u63a2\u8ba8Toll\u6837\u53d7\u4f53\u9002\u914d\u86cb\u767d\u542b\u65e0\u83cc\u03b1\u57fa\u5e8f\u53caToll/\u767d\u4ecb\u7d20\u53d7\u4f53\u57fa\u5e8f\u86cb\u767d1\uff08SARM1\uff09\u8c03\u63a7\u8f74\u7a81\u7ebf\u7c92\u4f53\u951a\u5b9a\u86cb\u767d\uff08SNPH\uff09\u8868\u8fbe\u53c2\u4e0e\u9752\u5149\u773c\u89c6\u795e\u7ecf\u75c5\u53d8\u7684\u673a\u5236\u3002 \u65b9\u6cd5\uff1a \u5b9e\u9a8c\u7814\u7a76\uff0c\u4e8e2024\u5e742\u6708\u81f32025\u5e7410\u6708\u5f00\u5c55\u3002\u7528\u7b80\u5355\u968f\u673a\u6cd5\u5c068~10\u5468Wistar\u96c4\u6027\u5927\u9f20\u5206\u4e3a\u5bf9\u7167\u7ec4\u548c\u9752\u5149\u773c\u6a21\u578b\u7ec4\uff0c\u6bcf\u7ec46\u53ea\u52a8\u7269\uff0c\u5747\u53d6\u53f3\u773c\u7eb3\u5165\u5b9e\u9a8c\u3002\u6a21\u578b\u7ec4\u8fdb\u884c\u524d\u623f\u5fae\u7c92\u78c1\u73e0\u6ce8\u5c04\uff0c\u6784\u5efa\u6162\u6027\u9ad8\u773c\u538b\u9752\u5149\u773c\u6a21\u578b\uff0c\u5728\u9020\u6a21\u540e3 d\u30011\u5468\u548c2\u5468\u53d6\u89c6\u7f51\u819c\u548c\u89c6\u795e\u7ecf\u8fdb\u884c\u5b9e\u9a8c\uff1b\u5bf9\u7167\u7ec4\u5927\u9f20\u524d\u623f\u6ce8\u5c04\u7b49\u4f53\u79ef\u751f\u7406\u76d0\u6c34\u3002\u4f7f\u7528TonoLab\u773c\u538b\u8ba1\u6d4b\u91cf\u5927\u9f20\u773c\u538b\u3002\u91c7\u7528\u89c6\u7f51\u819c\u94fa\u7247Brn3A\u514d\u75ab\u8367\u5149\u67d3\u8272\u68c0\u6d4b\u89c6\u7f51\u819c\u795e\u7ecf\u8282\u7ec6\u80de\uff08RGC\uff09\u4e22\u5931\u60c5\u51b5\u3002\u91c7\u7528Western\u5370\u8ff9\u68c0\u6d4b\u5927\u9f20\u89c6\u7f51\u819c\u548c\u89c6\u795e\u7ecf\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\u60c5\u51b5\u3002\u91c7\u7528\u514d\u75ab\u8367\u5149\u67d3\u8272\u6cd5\u68c0\u6d4b\u5927\u9f20SARM1\u548cSNPH\u5728\u89c6\u7f51\u819c\u548c\u8f74\u7a81\u4e2d\u7684\u8868\u8fbe\u5206\u5e03\u60c5\u51b5\u3002\u5e76\u5229\u7528\u6210\u7c07\u89c4\u5f8b\u95f4\u9694\u77ed\u56de\u6587\u91cd\u590d\u5e8f\u5217\uff08CRISPR\uff09/\u6838\u9178\u5185\u5207\u91769\uff08Cas9\uff09\u6280\u672f\u5206\u522b\u964d\u4f4e\u5c0f\u9f20\u89c6\u7f51\u819c\u795e\u7ecf\u8282\u7ec6\u80de\u7cfb661W\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\uff0c\u8f6c\u67d348 h\u540e\u6536\u96c6\u7ec6\u80de\u3002\u91c7\u7528Western\u5370\u8ff9\u68c0\u6d4b\u7ec6\u80de\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\u60c5\u51b5\u3002\u91c7\u7528\u72ec\u7acb\u6837\u672ct\u68c0\u9a8c\u3001\u5355\u56e0\u7d20\u65b9\u5dee\u5206\u6790\u3001Tukey\u591a\u91cd\u6bd4\u8f83\u8fdb\u884c\u7edf\u8ba1\u5b66\u5206\u6790\u3002 \u7ed3\u679c\uff1a Western\u5370\u8ff9\u7ed3\u679c\u663e\u793a\uff0c\u6a21\u578b\u7ec4\u9020\u6a21\u540e1\u5468\uff0c\u89c6\u795e\u7ecf\u4e2d\u7684SARM1\u86cb\u767d\u7684\u76f8\u5bf9\u8868\u8fbe\u91cf\uff081.22\u00b10.06\uff09\u9ad8\u4e8e\u5bf9\u7167\u7ec4\uff081.03\u00b10.01\uff0cP=0.027\uff0cq=4.38\uff09\u3002\u800c\u89c6\u7f51\u819c\u4e2dSARM1\u86cb\u767d\u8868\u8fbe\u91cf\u5728\u9020\u6a21\u540e3 d\uff080.79\u00b10.02\uff09\u4f4e\u4e8e\u5bf9\u7167\u7ec4\uff081.04\u00b10.03\uff0cP<0.001\uff0cq=6.86\uff09\u3002SNPH\u7684\u8868\u8fbe\u91cf\u5728\u9020\u6a21\u540e3 d\uff080.74\u00b10.01\uff09\u4f4e\u4e8e\u5bf9\u7167\u7ec4\uff081.03\u00b10.04\uff0cP=0.040\uff0cq=0.58\uff09\uff0c\u5e76\u5728\u9020\u6a21\u540e1\u5468\uff081.19\u00b10.10\uff0cP=0.002\uff0cq=4.36\uff09\u8868\u8fbe\u91cf\u9ad8\u4e8e\u9020\u6a21\u540e3 d\uff080.74\u00b10.01\uff09\u3002\u514d\u75ab\u8367\u5149\u67d3\u8272\u7ed3\u679c\u663e\u793a\uff0c\u6a21\u578b\u7ec4RGC\u8f74\u7a81\u4e2dSARM1\u7684\u8868\u8fbe\u5728\u9020\u6a21\u540e1\u5468\u9ad8\u4e8e\u5bf9\u7167\u7ec4\uff0cSNPH\u7684\u8868\u8fbe\u5728\u9020\u6a21\u540e3 d\u4f4e\u4e8e\u5bf9\u7167\u7ec4\u4e0eWestern\u5370\u8ff9\u7ed3\u679c\u4e00\u81f4\u3002\u5e76\u4e14\u90fd\u4e0e\u795e\u7ecf\u5143\u6807\u5fd7\u7269\u5fae\u7ba1\u86cb\u767d\u90e8\u5206\u5171\u5b9a\u4f4d\u3002\u5e76\u4e14\u514d\u75ab\u8367\u5149\u67d3\u8272\u7ed3\u679c\u8fd8\u663e\u793a\u8fd9\u4e24\u79cd\u86cb\u767d\u5728\u89c6\u795e\u7ecf\u4e2d\u5171\u5b9a\u4f4d\u3002SARM1\u4e0e\u7ebf\u7c92\u4f53\u6807\u5fd7\u7269\u86cb\u767dTOM20\u5171\u5b9a\u4f4d\u3002661W\u7ec6\u80de\u4e2dWestern\u5370\u8ff9\u7ed3\u679c\u663e\u793a\uff0cSARM1\u8868\u8fbe\u964d\u4f4e\uff080.54\u00b10.04\uff09\u53ef\u964d\u4f4eSNPH\uff080.54\u00b10.05\uff0cP=0.003\uff0cq=7.98\uff09\u7684\u8868\u8fbe\uff0c\u4f46SNPH\u8868\u8fbe\u964d\u4f4e\uff080.39\u00b10.06\uff09\u5bf9SARM1\u8868\u8fbe\u5f71\u54cd\u8f83\u5c0f\uff080.75\u00b10.05\uff0cP=0.010\uff0cq=6.39\uff09\u3002 \u7ed3\u8bba\uff1a SARM1\u86cb\u767d\u5728\u5927\u9f20\u9752\u5149\u773c\u6a21\u578b\u7ec4\u4e2d\u7684\u89c6\u795e\u7ecf\u4e2d\u8868\u8fbe\u5347\u9ad8\uff0c\u901a\u8fc7\u5b9a\u4f4d\u4e8e\u7ebf\u7c92\u4f53\u8c03\u63a7SNPH\u8868\u8fbe\u53c2\u4e0eRGCs\u89c6\u795e\u7ecf\u75c5\u53d8\u3002."

Stx4 is predominantly localized at the postsynaptic membrane of neurons and in glial cells, where it is essential for synaptic plasticity and the maintenance of neuronal homeostasis. Stx4 facilitates the activity-dependent exocytosis of glutamatergic receptors, thereby governing the balance between Long-Term Potentiation (LTP) and Long-Term Depression (LTD). Emerging evidence suggests that dysregulation of Stx4 is intricately linked to the pathogenesis of neurodegenerative diseases. In Alzheimer's disease, Stx4 is involved in synaptic dysfunction and cognitive impairment through its interactions with amyloid-\u03b2 (A\u03b2) and tau pathologies, affecting receptor recruitment at dendritic spines. In Parkinson's Disease (PD), Stx4 contributes to \u03b1-synuclein proteostasis, dopaminergic signaling, neuroinflammation, and the maintenance of blood-brain barrier integrity. While its presence in cerebrospinal fluid highlights its potential as a candidate biomarker for these diseases, further validation is required to establish clinical utility. This review summarizes current mechanistic insights into Stx4's multifaceted roles in the neurodegenerative disorders and explores the therapeutic prospects of targeting Stx4-mediated pathways due to its translational potential."

This study investigated whether L-serine supplementation could attenuate DN through dose-dependent metabolic and neuroprotective mechanisms in a high-fat diet (HFD) plus streptozotocin (STZ)-induced diabetic rat model. Male Wistar rats (n = 8 per group) were allocated to five groups: normal control (NC), diabetic control (DC), pioglitazone (PIO; 1.5 mg/kg/day), low-dose L-serine (S1; 200 mg/kg/day), and high-dose L-serine (S2; 400 mg/kg/day). After 60 days of oral gavage, behavioural testing, glucose and insulin profiling, HOMA-IR calculation, brain histopathology, nerve growth factor (NGF) immunohistochemistry, and LC-MS/MS-based proteomic analysis of cerebral tissue were performed. Diabetic rats exhibited marked hyperglycaemia (355.33 \u00b1 4.72 mg/dL), hyperinsulinaemia, severe insulin resistance (HOMA-IR 16.8 \u00b1 3.2; a 14-fold increase), impaired thermal nociception, motor dysfunction, and pronounced neuronal degeneration. L-serine supplementation significantly improved metabolic status: S1 reduced HOMA-IR by 77.4% and S2 by 87.5% relative to diabetic controls (p < 0.001). High-dose L-serine produced greater improvements in thermal sensitivity, motor coordination (rotarod latency 26.67 \u00b1 1.52 s vs. 16.1 \u00b1 0.85 s in DC; p < 0.05), and NGF expression (8.6-fold increase vs. DC). Histopathology confirmed attenuation of neuronal injury and gliosis in both treatment groups. Exploratory, group-level proteomic profiling identified dose-specific molecular signatures: S1 was predominantly associated with carbohydrate, lipid, and biosynthetic pathways, whereas S2 was associated with synaptic, neurotransmission-related, and proteostasis pathways. Within the constraints of an exploratory design-group-level pooled proteomics, analysis of cerebral rather than peripheral-nerve tissue, and only two doses-these findings indicate that L-serine attenuates the metabolic and behavioural features of experimental diabetic neuropathy and generates the testable hypothesis of dose-dependent neuro-metabolic remodelling. The proteomic signatures are hypothesis-generating and require orthogonal validation before any mechanistic or translational inference can be drawn."

Methods: In this serial, cross-sectional study, 3 \u00d7 3 mm2 macular OCTA images were obtained from healthy adults and adults with diabetes mellitus (DM) with no diabetic retinopathy (DR) or with mild non-proliferative DR (NPDR). The parameters analyzed included foveal avascular zone (FAZ) area and perimeter, vessel density (VD), vessel length density (VLD), and flow index (FI) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP). The associations between OCTA parameters and age were explored using multivariable linear regression models. Results: For the included 1855 patients (1855 eyes) (49% male; mean age: 55 years), the results were as follows: no diabetes (N = 217), DM no DR (N = 1352), and mild NPDR (N = 286). Increasing age was significantly associated with decreased SCP and DCP VD and VLD in the diabetic and non-diabetic groups. The slope of association between SCP and DCP FI and age in the diabetic patients was significantly different than that in the control patients. Conclusions: The strength of the association between aging and OCTA parameters differed significantly between the controls and those with early retinopathy, pointing to a potentially altered retinal vascular homeostasis secondary to diabetic pathophysiology. This finding offers insight into the early pathological biomarkers of DR and may guide early DR management for patients based on personalized risk scores."

As a result, the treatment of neuropathic pain often requires a multifaceted approach. It has been shown that magnesium ions (Mg2+), which act as physiological antagonists of NMDARs, can augment opioid analgesia in chronic pain. The aim of this study was to assess the influence of Mg2+ on the electrophysiological, analgesic, and brain-derived neurotrophic factor (BDNF)-induced neuromodulation of the morphine profile in diabetic rats. Diabetes in male Wistar rats was induced by a single intramuscular injection of streptozotocin (STZ). The Plantar Test was used to assess the effect of Mg2+ and morphine co-treatment on STZ-induced hyperalgesia, expressed as increased warm sensitivity of the experimental rat hind paw. Ex vivo whole-cell recordings from ventrolateral periaqueductal gray (vlPAG) neurons were conducted to evaluate the frequency of action potentials evoked by incremental depolarizing current steps (current-clamp, 1-s steps). To assess glutamatergic signaling, neurons were voltage-clamped to measure NBQX-sensitive current at -70\u00a0mV and NMDA-evoked currents during depolarization in the presence of NMDA/glycine. Changes in BDNF concentrations in PAG structures were measured using an enzyme-linked immunosorbent assay. The results of our study suggest that although magnesium sulfate shows limited analgesic properties when administered alone, it can significantly enhance opioid efficacy when used as an adjunct. Moreover, the co-administration of morphine with magnesium sulfate resulted in a greater reduction in NMDA-evoked currents in diabetic rats compared to either agent alone. Overall, our findings support the concurrent use of Mg2+ and morphine in the treatment of neuropathic pain as a mechanism-informed adjunct strategy."

Here, we investigate Piezo2 function in the anterior visual pathway of the central nervous system with a focus on oligodendrocyte (OL) biology and myelin integrity. Using single-nucleus RNA sequencing, we identify Piezo2 expression in late differentiated OLs of the murine optic nerve, with minor expression in retinal ganglion cells. OL-specific Piezo2 deficiency results in age-dependent motor impairment and selective disruption of myelin compaction in small-caliber optic nerve axons, a fiber population known to be particularly vulnerable in demyelinating disease. Differential gene expression analysis further indicates that Piezo2 regulates myelin compaction and white matter integrity in mature OLs. Consistent with these findings, OL-encoded PIEZO2 expression is reduced in optic nerve lesion areas from multiple sclerosis patients, highlighting a convergent mechanism of small-caliber fiber vulnerability. Together, these data identify Piezo2 as an age-related regulator of OL function and myelin integrity, with potential relevance for preserving white matter structure in multiple sclerosis."

Whether this expansion represents a coherent transition toward smart, manufacturable, and function-oriented tissue-engineering systems remains unclear. We conducted an AI-assisted, rule-guided, and manually audited evidence architecture reconstruction of glaucoma-related biomaterial studies published from 2006 to 2025. Records from Web of Science Core Collection, Scopus, and PubMed were integrated, deduplicated, parsed from RIS files, screened, and quality controlled. Retained studies were classified by application scenario, evidence level, and translational features. Core evidence records were assigned to five operational levels, from material preparation and physicochemical characterization to disease-microenvironment intervention, long-term functional integration, and clinical or advanced translational evidence. Theme maturity and the convergence of smart material, additive manufacturing, and tissue-engineering relevance were further assessed. From 1,227 parsed records, 596 were retained, including 547 core evidence studies and 49 review or background records. In the core evidence set, Level 1 to Level 5 evidence included 93, 57, 140, 99, and 158 records, respectively. Level 1-3 evidence accounted for 53.0% of the core evidence set, whereas Level 4-5 evidence accounted for 47.0%, indicating a substantial but unevenly distributed translational component. In situ hydrogels and contact lens-based delivery systems represented the largest application categories, whereas retinal ganglion cell protection, trabecular meshwork modeling, anti-fibrosis after glaucoma surgery, GDD/MIGS-related interfaces, and 3D printing represented smaller but more disease-specific or integration-oriented domains. Glaucoma-related biomaterials are moving beyond passive delivery platforms, but their transition toward smart materials, additive manufacturing, and functional tissue engineering remains uneven. Future studies should emphasize reproducible material design, disease-relevant functional endpoints, outflow-pathway models, neuroprotection, and engineered surgical interfaces."

A rat DR model was established and treated with BBR, and histological analyses, including hematoxylin and eosin staining, Nissl staining, and immunofluorescence, were executed to evaluate tissue changes. Core target genes were identified using the GeneCards database, Venn diagram analysis, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment, protein-protein interaction networks, and molecular docking. Validation of key genes was performed via reverse transcription-quantitative polymerase chain reaction (RT-qPCR), Western blot, and RNA interference. BBR improved retinal morphology, reduced edema, and restored the arrangement of retinal ganglion cells in DR rats. BBR significantly reduced the levels of pyroptosis markers such as IL-1\u03b2 and IL-18, which were elevated in DR. Network pharmacology identified 10 hub genes, with six genes (JUN, STAT3, AKT1, TP53, IL-1B, EGFR) further analyzed. BBR reversed DR-induced upregulation of JUN, STAT3, and AKT1 at both the mRNA and protein levels, as confirmed by RT-qPCR and Western blot. Silencing these genes enhanced cell viability and amplified BBR's protective effects. Altogether, BBR alleviates retinal inflammation and pyroptosis in diabetic retinal ganglion cells by targeting JUN, STAT3, and AKT1, providing insights into its therapeutic potential for DR."

Within the RNVU, calcium ions coordinate neurotransmission, glial activation, vascular tone, and blood-retinal barrier maintenance, and calcium dysregulation is emerging as a unifying pathogenic hub across these conditions. Although upstream triggers differ, including mechanical stress in glaucoma, hyperglycemia in DR, oxidative damage in AMD, ischemic energy failure in RIR, and amyloid-\u03b2-driven endoplasmic reticulum stress in AD, all converge on disruption of intracellular calcium homeostasis, producing shared downstream consequences including excitotoxic injury of retinal ganglion cells (RGCs), M\u00fcller cell reactive gliosis, and pericyte hypercontraction. Broad-spectrum calcium channel blockade has shown limited clinical success, underscoring the need for cell-type-specific and pathway-selective approaches. This review therefore catalogs key interventional nodes, including transient receptor potential (TRP) channel antagonists, T-type calcium channel inhibitors, calcium/calmodulin-dependent protein kinase II (CaMKII) suppressors, and mitochondrial permeability transition pore (mPTP) inhibitors, and discusses how precision targeting of these pathways may restore RNVU homeostasis and open a therapeutic window into central nervous system (CNS) degenerative disorders."

In this study, we investigated the protective effects of norrin against hyperglycemia-induced retinal neurodegeneration and elucidated its underlying molecular mechanisms in diabetic mice. We found that retinal neurodegeneration may precede microvascular leakage in diabetic retinas. Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Intravitreal supplementation of norrin markedly attenuated hyperglycemia-induced neurodegenerative processes, leading to retinal ganglion cell (RGC) apoptosis, including oxidative stress, inflammation, and neuropathological alterations such as reactive gliosis, glutamate excitotoxicity, and synaptic dysfunction. Norrin also reduced hyperglycemia-induced microvascular leakage and RGC apoptosis by normalizing vascular endothelial growth factor (VEGF) overexpression and restoring pigment epithelium-derived factor (PEDF) levels. Notably, PEDF upregulated by norrin effectively suppressed neurodegenerative processes induced by hyperglycemia or VEGF, thereby preserving RGC function. These findings identify norrin as a critical modulator of hyperglycemia-induced retinal neurodegeneration through restoration of the VEGF-PEDF balance. Our results highlight norrin as a potential therapeutic target for early neurodegenerative changes in diabetic retinopathy."

This study sought to determine the effects of pelargonidin on extracellular matrix (ECM) modulation and the inhibition of transforming growth factor-\u03b2 (TGF-\u03b2) and Janus Kinase 2/Signal Transducer and Activator of Transcription 3 (JAK2/STAT3) pathway in retinal ganglion cells of streptozotocin-induced diabetic rats. Male Sprague-Dawley rats (180-200 g) were rendered diabetic by intraperitoneal administration of streptozotocin (STZ). The rats were divided into 5 groups: control, diabetic model (STZ), STZ + low dose pelargonidin (12.5 mg kg-1 per day), STZ + medium dose pelargonidin (25 mg kg-1 per day) and STZ + high dose pelargonidin (50 mg kg-1 per day). IOP was monitored using a tonometer. Whole-mount retinal immunofluorescence staining using RNA-binding protein with multiple splicing (RBPMS) was performed to assess retinal ganglion cell (RGC) density. Protein expression levels of apoptotic markers, ECM components, and TGF-\u03b2 and JAK2/STAT3 signalling pathways were evaluated by Western blotting. Pelargonidin treatment dose-dependently reduced the elevated IOP. Importantly, immunofluorescence analysis revealed a marked dose-dependent preservation of retinal ganglion cell (RGC) density: STZ-induced RGC loss was significantly reversed by pelargonidin, with the highest dose restoring RGC density to near-control or higher levels in both the central and peripheral retina. This was achieved via modulation of apoptosis-related proteins through the upregulation of Bcl-xL, Bcl-2, and downregulation of Bad, Bax and cleaved caspase-3. Furthermore, pelargonidin modulated ECM remodelling protein expression in the RGC layer. In particular, TGF-\u03b22/Smad2/3 signalling was downregulated, and the JAK2/STAT3 pathway was upregulated. By reducing IOP, preserving RGC density, modulating ECM deposition, inhibiting TGF-\u03b2 and upregulating the JAK2/STAT3 pathway, pelargonidin exerts protective effects against diabetic retinal injury. The results of this study further confirm the pharmacological potential of pelargonidin as a therapeutic agent for diabetic retinopathy."

Patients often develop other symptoms, such as deafness and neurological dysfunction. Wolfram syndrome is caused by mutations in the WFS1 gene, which encodes wolframin protein. Despite decades of intensive research, the complex mechanisms of optic neuropathy are not fully understood, and there are currently no therapies to prevent vision loss in Wolfram patients. Here, we showed that the Wfs1 knockout mice produced by the Estonian group, in which exon 8 of the Wfs1 gene was disrupted, exhibit a progressive loss of visual acuity, optic disc pallor and severe optic nerve damage. We tested the efficiency of gene therapy using AAV2 to deliver human WFS1 to retinal ganglion cells in Wfs1 knockout mice. Our results provide the first evidence that intravitreal injection of human WFS1 has significant neuroprotective effects on retinal ganglion cells and their axons and slows the loss of visual acuity. These results demonstrate that WFS1 is able to provide both functional and structural protection to retinal ganglion cells in Wfs1 knockout mice and provide important evidence for the efficacy of WFS1 as a neuroprotective treatment for Wolfram syndrome. These results demonstrate the promising effects of gene therapy for Wolfram syndrome and encourage future research aimed at conducting clinical trials in patients."

Group I mGluRs (mGluR1 and mGluR5) interact with PSD adaptor and scaffolding proteins, such as Homer, Shank, Norbin, and PICK1, as well as intracellular downstream effectors, creating a molecular network that resembles a Lego-like structure, where modular protein interactions fine-tune glutamatergic transmission. Evidence from preclinical research indicates that dysregulation of mGluR expression and function, along with disrupted PSD protein expression, may contribute to the pathophysiology of schizophrenia by altering glutamatergic neurotransmission and synaptic stability. Antipsychotic mechanisms of action may involve, at least in part, the modulation of mGluR activity mediated through PSD proteins. Notably, novel agents that enhance spinogenesis by acting at the level of PSD proteins, such as SPG302, may open promising avenues for therapeutics aimed at restoring synaptic integrity. While Group I mGluRs dominate postsynaptic regulation, Group II (mGluR2/3) and III (mGluR4/6/7/8) receptors -primarily presynaptic- inhibit neurotransmitter release and plasticity, offering complementary therapeutic avenues. Emerging strategies, such as allosteric modulators of mGluRs, aim to rebalance synaptic signaling in treatment-resistant schizophrenia. This review synthesizes how PSD proteins and mGluRs interact in schizophrenia, exploring their potential as druggable targets for novel therapies."

The current study is aiming to test the effect of oral betanin doses in protection from DIR in rats along with a network pharmacology study to investigate an assumption that betanin may inhibit nuclear factor-\u03ba B (NF-\u03baB). Three rat groups were assigned as vehicle, DIR, and DIR\u00a0+\u00a0Betanin 100\u00a0mg/kg. Molecular docking indicated the possible binding between betanin and NF-\u03baB while the bioinformatic study highlighted a relation between this possible inhibition and suppression of NOD-like receptor pyrin domain-containing protein 3/vascular endothelial growth factor (NLRP3/VEGF) axis.

We investigate the feasibility and mechanisms of SRR inhibition as a strategy to prevent DR. SRR proteins in the retinas of db/db mice were approximately 50\u00a0% higher than C57BLKS/J wild-type (WT) mice, while D-serine levels in the aqueous humor were more than two-fold higher. Oral gavage of l-aspartic acid \u03b2-hydroxamate (L-ABH) improved b-wave amplitudes in electroretinogram recordings under both photopic and scotopic conditions. It also protected the inner retina in db/db mice by reducing the loss of retinal ganglion cells, endothelial cells, and pericytes, as well as decreasing the activation of M\u00fcller cells. In high glucose and hypoxia, interleukin-1 and interleukin-18 mRNA levels were lower in Srr-deleted M\u00fcller cell cultures than in WT cultures. Intravitreal injection of L-ABH mitigated glutamate-induced neurotoxicity in the retina. Systemically, L-ABH maintained euglycemia and improved glucose tolerance in db/db mice by inhibiting liver gluconeogenesis through restricting the expansion of pancreatic islet \u03b1-cells.

Significant reductions in GCIPLT and GCIPLT/RT occurred only in the non-DR group, with GCIPLT decreasing by -0.229 \u00b5m/y (95% CI = -0.313 to -0.144; P < .001) and 0.324 % (95% CI = 0.444 to 0.204; P < .001), approximately 5-fold faster than in the control group. After adjusting for confounding factors, the longitudinal rates of RT, GCIPLT, and GCIPLT/RT were significantly accelerated in the non-DR group compared to the control group by -0.603 \u00b5m/y (95% CI = -0.939 to -0.268; P < .001), -0.189 \u00b5m/y (95% CI = -0.306 to -0.073; P = .001), and -0.073 % (95% CI = -0.118 to -0.028; P = .001), respectively. Although longitudinal changes in SCP vessel density did not show significant differences between the 2 groups (P = .861). Our findings suggest that neurodegenerative changes may precede microvascular alterations in non-DR patients, indicating that monitoring of GCIPLT is crucial for patients with long-standing diabetes, even in the absence of retinopathy."

The mechanisms leading to neuro-retinal cell loss before vascular complications manifest in diabetes remain poorly understood. In this study, we investigated the neuronal RNA-binding protein HuD as a novel regulator of neuro-retinal degeneration in the early stage of diabetes. We determined the expression of HuD and alpha-crystallin A (CRYAA) in the retinal ganglion cell layer. HuD and CRYAA were down-regulated in the retinas of streptozotocin-induced diabetic rats and in neuro-retinal cells (R-28) treated with high glucose. Cryaa mRNA was identified as a novel target transcript of HuD, and we demonstrated that HuD post-transcriptionally regulates the expression of Cryaa mRNA by binding to its 3'-untranslated region. Silencing and overexpression of HuD positively regulated the expressions of Cryaa mRNA and protein. We demonstrated that the increase in inflammatory cytokines such as TNF\u03b1, IL-1\u03b2, and IL-6 in R-28 cells under hyperglycemic conditions was a result of both CRYAA and HuD levels. Silencing HuD and CRYAA enhanced high glucose-induced R-28 cell death, whereas their overexpression alleviated this effect. HuD post-transcriptionally regulates CRYAA expression, influencing the function and viability of neuro-retinal cells under diabetic conditions. Our results suggest that the HuD/CRYAA axis plays a crucial role in neuro-retinal cells and has the potential to serve as a prognostic factor and therapeutic target for diabetic neuro-retinal degeneration."

DJ-1 (PARK7) acts as a crucial antioxidant defense mechanism, stabilizing mitochondrial structure and redox balance. However, its expression is dramatically suppressed under diabetic conditions, and the upstream regulatory mechanisms remain incompletely characterized. Growing evidence from epigenetic research implicates microRNAs (miRNAs) as important players in the molecular pathways underlying DR progression. Among these, miRNA-122-5p has drawn increasing attention due to its aberrant activity under diabetic stress and its putative interaction with PARK7. In this study, we employed a streptozotocin-induced type 1 diabetes mouse model and glucose-stimulated R28\u00a0cells to explore the contribution of miRNA-122-5p to mitochondrial damage, oxidative stress, and RGC injury. In diabetic mice, we observed significant oxidative imbalance, increased apoptotic activity, RGC loss, and diminished retinal function. MiRNA profiling identified miRNA-122-5p as the most upregulated among candidate miRNAs. Inhibition of miRNA-122-5p attenuated these pathological changes and preserved both cellular integrity and visual function. In vitro, high glucose triggered mitochondrial fragmentation, membrane potential collapse, and excessive reactive oxygen species generation in R28\u00a0cells. Suppressing miRNA-122-5p alleviated these injuries. Dual-luciferase assays confirmed that miRNA-122-5p directly targets PARK7, thereby post-transcriptionally repressing DJ-1 expression and compromising mitochondrial resilience. These findings establish miRNA-122-5p as a critical upstream regulator of DJ-1-mediated antioxidant defense. By aggravating mitochondrial oxidative stress, it contributes to RGC vulnerability in DR. Targeted modulation of miRNA-122-5p may offer a novel therapeutic approach to preserve retinal neurons and counteract neurodegeneration in DR."

In this study, we examined whether EMPA protects against N-methyl-d-aspartic acid (NMDA)-induced retinal excitotoxicity and the mechanisms underlying its protective effects. Male Sprague-Dawley rats (7-8\u00a0weeks old) were used in this study. The number of cells in the ganglion cell layer (GCL) decreased 7\u00a0days after intravitreal injection of NMDA (50\u00a0nmol). Simultaneous intravitreal injection of EMPA (50 and 100\u00a0nmol) and NMDA reduced NMDA-induced cell loss in a dose-dependent manner. The protective effect of EMPA was significantly attenuated by the AMP-activated protein kinase (AMPK) inhibitor, compound C (10\u00a0nmol). NMDA increased the number of terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive cells in the GCL 6\u00a0h after injection, and the response was significantly, but not completely, attenuated by EMPA. These results suggest that EMPA protects against NMDA-induced retinal excitotoxicity in rats. The protective effect of EMPA may be partly attributed to the activation of the AMPK pathway and inhibition of neuronal cell apoptosis."

However, the detailed molecular regulatory mechanism has not yet been thoroughly examined. In this study, primary mouse RGCs were stimulated with different concentrations of glucose, and mouse was intraperitoneally injected with streptozotocin (STZ) to construct DR model in vitro and in vivo. We found that compared to normal controls, RNA binding motif protein 15 (RBM15) was significantly upregulated in high glucose-treated RGCs and STZ-induced mice. RBM15 silence restored cell viability and inhibited cell apoptosis and cell death in high glucose-triggered RGCs. In parallel, RBM15 knockdown distinctly improved pathological damage such as thinning of retinal tissue thickness and loss of RGCs in STZ-modeling mice. Interestingly, the production of inflammatory cytokines and the expression of Cleaved caspase-1, NLRP3 and GSDMD-N were significantly reduced by RBM15 silence in vivo and in vitro. Mechanistically, RBM15 bound to kruppel like factor 6 (KLF6) mRNA to promote m6A modification and stabilize KLF6 mRNA, upregulating KLF6 expression in model cells and model mice retinal tissues. KLF6 overexpression increased the production of inflammatory cytokines and the expression of proteins related to pyroptosis, reversing the protective effects of RBM15 silence in high glucose-treated RGCs and diabetic retina. In conclusion, RBM15 is upregulated by high glucose, and stabilizes KLF6 mRNA to activate NLRP3-mediated pyroptosis pathway, exacerbating inflammation and apoptosis of RGCs and accelerating the progression of DR."

The purpose of this study was to investigate the correlation of serum pro-BNP with optical coherence tomography (OCT) indices in diabetic retinopathy. This cross-sectional study investigated 96 consecutive subjects aged between 40 and 65 years: controls n = 24, no diabetic retinopathy (NoDR) n = 24, non-proliferative diabetic retinopathy (NPDR) n = 24, and proliferative diabetic retinopathy (PDR) n = 24. Same-day analysis of blood samples for serum pro-BNP levels was performed and spectral-domain OCT (SD-OCT) was used to measure the following OCT indices: OCT angiography (OCTA) superficial vessel density (SVD), deep vessel density (DVD), and foveal avascular zone (FAZ); OCT retinal nerve fiber layer (RNFL); and OCT ganglion cell analysis (GCA). The mean serum pro-BNP levels for the control, NoDR, NPDR, and PDR groups were 14.07 \u00b1 11.51, 27.35 \u00b1 11.81, 280.44 \u00b1 106.13, and 122.33 \u00b1 43.66 pg/ml, respectively.

The Ca2+/calmodulin-dependent protein kinase II alpha (CaMK2A) and cAMP response element-binding protein (CREB) signaling pathway has been implicated in various neurological disorders. However, its role in DR pathogenesis remains elusive. We established a DR mouse model by streptozotocin administration and performed histological, biochemical, and molecular analyses to investigate the involvement of CaMK2A/CREB signaling and its interplay with mitophagy. Additionally, we employed in vitro high-glucose (HG) treatment in primary mouse retinal ganglion cells to dissect the underlying mechanisms. Pharmacological and genetic modulations were utilized to target CaMK2A/CREB pathway and mitophagy. In the DR model, we observed retinal degeneration, increased apoptosis, and reduced neurotransmitter production, accompanied by enhanced mitophagy and activation of the CaMK2A/CREB pathway. HG induction in retinal ganglion cells recapitulated these findings, and autophagy inhibition partially rescued cell death but failed to suppress CaMK2A/CREB activation, suggesting mitophagy as a downstream consequence. CaMK2A knockdown or CREB phosphorylation inhibition attenuated HG-induced mitophagy, apoptosis, and neurotransmitter depletion, while CREB activation exacerbated these effects. CaMK2A silencing mitigated DR progression, oxidative stress, inflammation, and neuronal loss, akin to dopamine/carbidopa administration in DR mouse model. Our findings reveal the involvement of CaMK2A/CREB signaling activation and enhanced mitophagy in DR, suggesting these pathways may be therapeutically relevant targets for DR management."

Diabetic patients underwent detailed systemic and ophthalmic examination including automated pupillometry. The pupillometer used a white stimulus and was equipped with a high-resolution infrared (880\u2009nm) camera. Static pupillary diameters were captured at different levels of background intensity-photopic high (100\u2009cd/m2), photopic low (10\u2009cd/m2), mesopic high (1\u2009cd/m2), and mesopic low (0.1\u2009cd/m2).

This study aimed to elucidate whether nitric oxide (NO) can modulate the TXNIP/NLRP3 inflammasome pathway and mitigate retinal neurovascular unit (NVU) damage during early DR. In an in vitro co-culture system, silencing TXNIP or NLRP3 in retinal microglia (RMG) significantly upregulated glial cell-derived neurotrophic factor (GDNF) and downregulated inducible nitric oxide synthase (iNOS) expression in retinal ganglion cells (RGC). Moreover, it resulted in decreased iNOS and vascular endothelial growth factor A (VEGFA) levels and enhanced the expression of tight junction proteins (Occludin and ZO-1) in retinal microvascular endothelial cells (RMEC), while also reducing NO release and inhibiting RMEC tube formation. Treatment with S-nitroso-N-acetyl penicillamine (SNAP), an NO donor, significantly downregulated TXNIP/NLRP3 inflammasome signaling in RMG, decreased RGC apoptosis, and inhibited tube formation in RMEC. It also upregulated GDNF, suppressed iNOS in RGC, decreased VEGFA, and improved tight junction proteins in RMEC. Treatment with 1400W, an iNOS inhibitor, resulted in decreased NO concentration and increased IL-1\u03b2 levels in the co-culture supernatant, without significantly affecting iNOS expression in RGC or RMEC. In an early DR rat model, Electroretinogram (ERG), Optical Coherence Tomography (OCT), Fluorescein Angiography (FFA), Evans blue assays, Immunofluorescence staining, and TUNEL staining confirmed that sodium nitroprusside (SNP), NO donor administration mitigated retinal neural and vascular dysfunction, and preserved retinal NVU integrity. Concurrently, SNP treatment reduced IL-1\u03b2 expression and increased GDNF and Occludin levels in the early DR retina. Genetic Association Database (GAD) enrichment analysis and protein-protein interaction (PPI) network validation indicated that NO functions as a downstream mediator of the TXNIP/NLRP3 inflammasome pathway and exhibits a strong association with DR. These findings suggest that NO mediates negative feedback in the TXNIP/NLRP3 inflammasome pathway to exert protective effects against retinal NVU dysfunction in early DR, thereby offering potential therapeutic strategies for early intervention in DR."

In the brain, defects in \u03b3-aminobutyric acid synaptic transmission are associated with pathophysiological and neurodegenerative disorders, whereas glucagon-like peptide-1 has demonstrated neuroprotective effects. However, it is not yet clear whether diabetes causes alterations in inhibitory input to retinal ganglion cells and whether and how glucagon-like peptide-1 protects against neurodegeneration in the diabetic retina through regulating inhibitory synaptic transmission to retinal ganglion cells. In the present study, we used the patch-clamp technique to record \u03b3-aminobutyric acid subtype A receptor-mediated miniature inhibitory postsynaptic currents in retinal ganglion cells from streptozotocin-induced diabetes model rats. We found that early diabetes (4 weeks of hyperglycemia) decreased the frequency of GABAergic miniature inhibitory postsynaptic currents in retinal ganglion cells without altering their amplitude, suggesting a reduction in the spontaneous release of \u03b3-aminobutyric acid to retinal ganglion cells. Topical administration of glucagon-like peptide-1 eyedrops over a period of 2 weeks effectively countered the hyperglycemia-induced downregulation of GABAergic mIPSC frequency, subsequently enhancing the survival of retinal ganglion cells. Concurrently, the protective effects of glucagon-like peptide-1 on retinal ganglion cells in diabetic rats were eliminated by topical administration of exendin-9-39, a specific glucagon-like peptide-1 receptor antagonist, or SR95531, a specific antagonist of the \u03b3-aminobutyric acid subtype A receptor. Furthermore, extracellular perfusion of glucagon-like peptide-1 was found to elevate the frequencies of GABAergic miniature inhibitory postsynaptic currents in both ON- and OFF-type retinal ganglion cells. This elevation was shown to be mediated by activation of the phosphatidylinositol-phospholipase C/inositol 1,4,5-trisphosphate receptor/Ca 2+ /protein kinase C signaling pathway downstream of glucagon-like peptide-1 receptor activation. Moreover, multielectrode array recordings revealed that glucagon-like peptide-1 functionally augmented the photoresponses of ON-type retinal ganglion cells. Optomotor response tests demonstrated that diabetic rats exhibited reductions in visual acuity and contrast sensitivity that were significantly ameliorated by topical administration of glucagon-like peptide-1. These results suggest that glucagon-like peptide-1 facilitates the release of \u03b3-aminobutyric acid onto retinal ganglion cells through the activation of glucagon-like peptide-1 receptor, leading to the de-excitation of retinal ganglion cell circuits and the inhibition of excitotoxic processes associated with diabetic retinopathy. Collectively, our findings indicate that the \u03b3-aminobutyric acid system has potential as a therapeutic target for mitigating early-stage diabetic retinopathy. Furthermore, the topical administration of glucagon-like peptide-1 eyedrops represents a non-invasive and effective treatment approach for managing early-stage diabetic retinopathy."

The drugs currently used for treatment, such as ranibizumab, mainly focus on the middle and late periods of DR, and thus do not meet the clinical need. Here, the potential mechanisms by which compound Danshen Dripping Pills (CDDP) might protect against early DR were investigated. Methods: Db/db mice were used to establish a DR model. The initial weights and HbA1c levels of the mice were monitored, and retinal pathology was assessed by hematoxylin-eosin (HE) staining. The vascular permeability of the retina and thickness of each retinal layer were measured, and electroretinogram were performed together with fundus fluorescein angiography and optical coherence tomography. The levels of inflammatory factors were examined in retinal tissue, as well as those of intercellular adhesion molecule 1 (ICAM-1), IL-6, and monocyte chemoattractant protein 1 (MCP-1) in the serum using ELISA. Immunohistochemistry was used to evaluate levels of vascular endothelial growth factor (VEGF), B-cell lymphoma 2 (Bcl-2), and Bclassociated X protein (Bax). Retinal cell injury and apoptosis were examined by TdT-mediated dUTP Nick End Labeling (TUNEL) assays. Results: The data showed that CDDP significantly improved cellular disarrangement. Imaging data indicated that CDDP could reduce vascular permeability and the amplitude of oscillatory potentials (OPs), and restore the thickness of the ganglion cell layer. Moreover, CDDP reduced the expression levels of inflammatory factors in both the retina and serum. Conclusion: These findings strongly suggest that CDDP prevents early DR through vascular and neuroprotection."

Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function, decreased inner retina synaptic markers, and increased reactive gliosis and cell death. Loss of glutamatergic synapses in the retina precedes, and may contribute to, overt neuron loss in DR, thus offering a potential new point for therapeutic intervention. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma, another leading cause of blindness associated with early synapse loss in the retina. To evaluate potential protective effects of SPG302 in DR, db/db mice (a diabetic mouse model with an inactivation mutation in the leptin receptor) were treated with intraperitoneal SPG302 or vehicle for 8 weeks (16-24 weeks of age). Db/+ mice served as an additional control. Db/db mice demonstrated weight gain, hyperglycemia, insulin intolerance, and glucose intolerance, while db/+ mice did not. SPG302 treatment did not change these metabolic parameters. Following treatment, GC function was assessed using electroretinography (ERG). Mice were then euthanized for quantification of retinal GCs, synaptic markers, glial markers, and markers of cell death using immunofluorescence staining and Western blot methods. Db/db mice demonstrated significant loss of GC ERG signal and GC cell number, decreased PSD95 and synaptophysin expression indicative of synapse loss, as well as increased reactive gliosis and expression of cell death markers such as pBAD and BAX.

Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function, decreased inner retina synaptic markers, and increased reactive gliosis and cell death. Loss of glutamatergic synapses in the retina precedes, and may contribute to, overt neuron loss in DR, thus offering a potential new point for therapeutic intervention. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma, another leading cause of blindness associated with early synapse loss in the retina. To evaluate potential protective effects of SPG302 in DR, db/db mice (a diabetic mouse model with an inactivation mutation in the leptin receptor) were treated with intraperitoneal SPG302 or vehicle for 8 weeks (16-24 weeks of age). Db/+ mice served as an additional control. Db/db mice demonstrated weight gain, hyperglycemia, insulin intolerance, and glucose intolerance, while db/+ mice did not. SPG302 treatment did not change these metabolic parameters. Following treatment, GC function was assessed using electroretinography (ERG). Mice were then euthanized for quantification of retinal GCs, synaptic markers, glial markers, and markers of cell death using immunofluorescence staining and Western blot methods. Db/db mice demonstrated significant loss of GC ERG signal and GC cell number, decreased PSD95 and synaptophysin expression indicative of synapse loss, as well as increased reactive gliosis and expression of cell death markers such as pBAD and BAX. SPG302 treatment effectively preserved retinal integrity by reversing these changes. Thus, SPG302 has therapeutic potential for protecting the inner retina and mitigating DRN in diabetes."

Within the RNVU, calcium ions coordinate neurotransmission, glial activation, vascular tone, and blood-retinal barrier maintenance, and calcium dysregulation is emerging as a unifying pathogenic hub across these conditions. Although upstream triggers differ, including mechanical stress in glaucoma, hyperglycemia in DR, oxidative damage in AMD, ischemic energy failure in RIR, and amyloid-\u03b2-driven endoplasmic reticulum stress in AD, all converge on disruption of intracellular calcium homeostasis, producing shared downstream consequences including excitotoxic injury of retinal ganglion cells (RGCs), M\u00fcller cell reactive gliosis, and pericyte hypercontraction. Broad-spectrum calcium channel blockade has shown limited clinical success, underscoring the need for cell-type-specific and pathway-selective approaches. This review therefore catalogs key interventional nodes, including transient receptor potential (TRP) channel antagonists, T-type calcium channel inhibitors, calcium/calmodulin-dependent protein kinase II (CaMKII) suppressors, and mitochondrial permeability transition pore (mPTP) inhibitors, and discusses how precision targeting of these pathways may restore RNVU homeostasis and open a therapeutic window into central nervous system (CNS) degenerative disorders."

In this study, we investigated the protective effects of norrin against hyperglycemia-induced retinal neurodegeneration and elucidated its underlying molecular mechanisms in diabetic mice. We found that retinal neurodegeneration may precede microvascular leakage in diabetic retinas. Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Intravitreal supplementation of norrin markedly attenuated hyperglycemia-induced neurodegenerative processes, leading to retinal ganglion cell (RGC) apoptosis, including oxidative stress, inflammation, and neuropathological alterations such as reactive gliosis, glutamate excitotoxicity, and synaptic dysfunction. Norrin also reduced hyperglycemia-induced microvascular leakage and RGC apoptosis by normalizing vascular endothelial growth factor (VEGF) overexpression and restoring pigment epithelium-derived factor (PEDF) levels. Notably, PEDF upregulated by norrin effectively suppressed neurodegenerative processes induced by hyperglycemia or VEGF, thereby preserving RGC function. These findings identify norrin as a critical modulator of hyperglycemia-induced retinal neurodegeneration through restoration of the VEGF-PEDF balance. Our results highlight norrin as a potential therapeutic target for early neurodegenerative changes in diabetic retinopathy."

Patients often develop other symptoms, such as deafness and neurological dysfunction. Wolfram syndrome is caused by mutations in the WFS1 gene, which encodes wolframin protein. Despite decades of intensive research, the complex mechanisms of optic neuropathy are not fully understood, and there are currently no therapies to prevent vision loss in Wolfram patients. Here, we showed that the Wfs1 knockout mice produced by the Estonian group, in which exon 8 of the Wfs1 gene was disrupted, exhibit a progressive loss of visual acuity, optic disc pallor and severe optic nerve damage. We tested the efficiency of gene therapy using AAV2 to deliver human WFS1 to retinal ganglion cells in Wfs1 knockout mice. Our results provide the first evidence that intravitreal injection of human WFS1 has significant neuroprotective effects on retinal ganglion cells and their axons and slows the loss of visual acuity. These results demonstrate that WFS1 is able to provide both functional and structural protection to retinal ganglion cells in Wfs1 knockout mice and provide important evidence for the efficacy of WFS1 as a neuroprotective treatment for Wolfram syndrome. These results demonstrate the promising effects of gene therapy for Wolfram syndrome and encourage future research aimed at conducting clinical trials in patients."

Retinal inflammation and angiogenesis contribute largely to the neuronal degeneration in DIR. The current study is aiming to test the effect of oral betanin doses in protection from DIR in rats along with a network pharmacology study to investigate an assumption that betanin may inhibit nuclear factor-\u03ba B (NF-\u03baB). Three rat groups were assigned as vehicle, DIR, and DIR\u00a0+\u00a0Betanin 100\u00a0mg/kg. Molecular docking indicated the possible binding between betanin and NF-\u03baB while the bioinformatic study highlighted a relation between this possible inhibition and suppression of NOD-like receptor pyrin domain-containing protein 3/vascular endothelial growth factor (NLRP3/VEGF) axis. The rat experimental study validated this assumption and indicated a protective effect for betanin on rat retinas as shown by routine hematoxylin and eosin staining (retinal thickness and ganglion cell count) and periodic acid-Schiff staining that was mediated through mitigating expression/protein level for of NF-\u03baB, NLRP3, TNF-\u03b1, IL-6 and VEGF proteins. Immunohistochemistry showed that betanin was able to suppress retinal content of the glial fibrillary acidic protein (GFAP). In conclusion, the current study indicated that betanin was a good candidate for DIR in rats through suppression of the inflammatory cascade and may be suggested for diabetic patients if appropriated clinical studies will be available."

The objective of the study was to determine the importance of ganglion cell complex (GCC) analysis as a parameter for diagnosis of glaucoma. This case control study was conducted in the Department of Ophthalmology, Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) General Hospital, Bangladesh over a period of one year from July 2017 to June 2018. Twenty five (25) Type-2 Diabetes control subjects and 50 subjects with Type-2 diabetes were divided into two groups, 25 diabetic with pre perimetric and 25 diabetic with perimetric glaucoma. In this study, there was no significant difference in age (50.92\u00b15.53 years vs. 52.44\u00b14.75 years vs. 52.64\u00b17.80 years), gender. Regarding Optical coherence tomography (OCT) Retinal Nerve Fiber Layer (RNFL) of right eyes of the study subjects, superior and inferior RNFL were significantly thinner in both pre-perimetric right eye (109.18\u00b18.95 and 111.21\u00b110.53) and perimetric right eye (90.28\u00b18.94 and 91.51\u00b17.87) comparing normal eyes (129.12\u00b12.68 and 132.17\u00b13.22).

Prospective observational cohort study. T2DM patients without clinical retinopathy at baseline and after a 2-year follow-up, along with age- and sex-matched healthy controls, were recruited from the community in Guangzhou, China. Measurements of macular GCIPLT, retinal thickness (RT), and SCP vessel density were conducted at baseline and at the 2-year follow-up. Linear mixed-effects models were used to estimate absolute and relative rates of changes and to compare absolute rates between the 2 groups. A total of 282 eyes (141 in the control group and 141 in the non-DR group) were included in the analysis. Significant reductions in GCIPLT and GCIPLT/RT occurred only in the non-DR group, with GCIPLT decreasing by -0.229 \u00b5m/y (95% CI = -0.313 to -0.144; P < .001) and 0.324 % (95% CI = 0.444 to 0.204; P < .001), approximately 5-fold faster than in the control group. After adjusting for confounding factors, the longitudinal rates of RT, GCIPLT, and GCIPLT/RT were significantly accelerated in the non-DR group compared to the control group by -0.603 \u00b5m/y (95% CI = -0.939 to -0.268; P < .001), -0.189 \u00b5m/y (95% CI = -0.306 to -0.073; P = .001), and -0.073 % (95% CI = -0.118 to -0.028; P = .001), respectively. Although longitudinal changes in SCP vessel density did not show significant differences between the 2 groups (P = .861). Our findings suggest that neurodegenerative changes may precede microvascular alterations in non-DR patients, indicating that monitoring of GCIPLT is crucial for patients with long-standing diabetes, even in the absence of retinopathy."

The mechanisms leading to neuro-retinal cell loss before vascular complications manifest in diabetes remain poorly understood. In this study, we investigated the neuronal RNA-binding protein HuD as a novel regulator of neuro-retinal degeneration in the early stage of diabetes. We determined the expression of HuD and alpha-crystallin A (CRYAA) in the retinal ganglion cell layer. HuD and CRYAA were down-regulated in the retinas of streptozotocin-induced diabetic rats and in neuro-retinal cells (R-28) treated with high glucose. Cryaa mRNA was identified as a novel target transcript of HuD, and we demonstrated that HuD post-transcriptionally regulates the expression of Cryaa mRNA by binding to its 3'-untranslated region. Silencing and overexpression of HuD positively regulated the expressions of Cryaa mRNA and protein. We demonstrated that the increase in inflammatory cytokines such as TNF\u03b1, IL-1\u03b2, and IL-6 in R-28 cells under hyperglycemic conditions was a result of both CRYAA and HuD levels. Silencing HuD and CRYAA enhanced high glucose-induced R-28 cell death, whereas their overexpression alleviated this effect. HuD post-transcriptionally regulates CRYAA expression, influencing the function and viability of neuro-retinal cells under diabetic conditions. Our results suggest that the HuD/CRYAA axis plays a crucial role in neuro-retinal cells and has the potential to serve as a prognostic factor and therapeutic target for diabetic neuro-retinal degeneration."

In this study, we examined whether EMPA protects against N-methyl-d-aspartic acid (NMDA)-induced retinal excitotoxicity and the mechanisms underlying its protective effects. Male Sprague-Dawley rats (7-8\u00a0weeks old) were used in this study. The number of cells in the ganglion cell layer (GCL) decreased 7\u00a0days after intravitreal injection of NMDA (50\u00a0nmol). Simultaneous intravitreal injection of EMPA (50 and 100\u00a0nmol) and NMDA reduced NMDA-induced cell loss in a dose-dependent manner. The protective effect of EMPA was significantly attenuated by the AMP-activated protein kinase (AMPK) inhibitor, compound C (10\u00a0nmol). NMDA increased the number of terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive cells in the GCL 6\u00a0h after injection, and the response was significantly, but not completely, attenuated by EMPA. These results suggest that EMPA protects against NMDA-induced retinal excitotoxicity in rats.

However, the detailed molecular regulatory mechanism has not yet been thoroughly examined. In this study, primary mouse RGCs were stimulated with different concentrations of glucose, and mouse was intraperitoneally injected with streptozotocin (STZ) to construct DR model in vitro and in vivo. We found that compared to normal controls, RNA binding motif protein 15 (RBM15) was significantly upregulated in high glucose-treated RGCs and STZ-induced mice. RBM15 silence restored cell viability and inhibited cell apoptosis and cell death in high glucose-triggered RGCs. In parallel, RBM15 knockdown distinctly improved pathological damage such as thinning of retinal tissue thickness and loss of RGCs in STZ-modeling mice. Interestingly, the production of inflammatory cytokines and the expression of Cleaved caspase-1, NLRP3 and GSDMD-N were significantly reduced by RBM15 silence in vivo and in vitro. Mechanistically, RBM15 bound to kruppel like factor 6 (KLF6) mRNA to promote m6A modification and stabilize KLF6 mRNA, upregulating KLF6 expression in model cells and model mice retinal tissues. KLF6 overexpression increased the production of inflammatory cytokines and the expression of proteins related to pyroptosis, reversing the protective effects of RBM15 silence in high glucose-treated RGCs and diabetic retina. In conclusion, RBM15 is upregulated by high glucose, and stabilizes KLF6 mRNA to activate NLRP3-mediated pyroptosis pathway, exacerbating inflammation and apoptosis of RGCs and accelerating the progression of DR."

Diabetic patients underwent detailed systemic and ophthalmic examination including automated pupillometry. The pupillometer used a white stimulus and was equipped with a high-resolution infrared (880\u2009nm) camera. Static pupillary diameters were captured at different levels of background intensity-photopic high (100\u2009cd/m2), photopic low (10\u2009cd/m2), mesopic high (1\u2009cd/m2), and mesopic low (0.1\u2009cd/m2).

In the brain, defects in \u03b3-aminobutyric acid synaptic transmission are associated with pathophysiological and neurodegenerative disorders, whereas glucagon-like peptide-1 has demonstrated neuroprotective effects. However, it is not yet clear whether diabetes causes alterations in inhibitory input to retinal ganglion cells and whether and how glucagon-like peptide-1 protects against neurodegeneration in the diabetic retina through regulating inhibitory synaptic transmission to retinal ganglion cells. In the present study, we used the patch-clamp technique to record \u03b3-aminobutyric acid subtype A receptor-mediated miniature inhibitory postsynaptic currents in retinal ganglion cells from streptozotocin-induced diabetes model rats. We found that early diabetes (4 weeks of hyperglycemia) decreased the frequency of GABAergic miniature inhibitory postsynaptic currents in retinal ganglion cells without altering their amplitude, suggesting a reduction in the spontaneous release of \u03b3-aminobutyric acid to retinal ganglion cells. Topical administration of glucagon-like peptide-1 eyedrops over a period of 2 weeks effectively countered the hyperglycemia-induced downregulation of GABAergic mIPSC frequency, subsequently enhancing the survival of retinal ganglion cells. Concurrently, the protective effects of glucagon-like peptide-1 on retinal ganglion cells in diabetic rats were eliminated by topical administration of exendin-9-39, a specific glucagon-like peptide-1 receptor antagonist, or SR95531, a specific antagonist of the \u03b3-aminobutyric acid subtype A receptor. Furthermore, extracellular perfusion of glucagon-like peptide-1 was found to elevate the frequencies of GABAergic miniature inhibitory postsynaptic currents in both ON- and OFF-type retinal ganglion cells. This elevation was shown to be mediated by activation of the phosphatidylinositol-phospholipase C/inositol 1,4,5-trisphosphate receptor/Ca 2+ /protein kinase C signaling pathway downstream of glucagon-like peptide-1 receptor activation. Moreover, multielectrode array recordings revealed that glucagon-like peptide-1 functionally augmented the photoresponses of ON-type retinal ganglion cells. Optomotor response tests demonstrated that diabetic rats exhibited reductions in visual acuity and contrast sensitivity that were significantly ameliorated by topical administration of glucagon-like peptide-1. These results suggest that glucagon-like peptide-1 facilitates the release of \u03b3-aminobutyric acid onto retinal ganglion cells through the activation of glucagon-like peptide-1 receptor, leading to the de-excitation of retinal ganglion cell circuits and the inhibition of excitotoxic processes associated with diabetic retinopathy. Collectively, our findings indicate that the \u03b3-aminobutyric acid system has potential as a therapeutic target for mitigating early-stage diabetic retinopathy. Furthermore, the topical administration of glucagon-like peptide-1 eyedrops represents a non-invasive and effective treatment approach for managing early-stage diabetic retinopathy."

Here, the potential mechanisms by which compound Danshen Dripping Pills (CDDP) might protect against early DR were investigated. Methods: Db/db mice were used to establish a DR model. The initial weights and HbA1c levels of the mice were monitored, and retinal pathology was assessed by hematoxylin-eosin (HE) staining. The vascular permeability of the retina and thickness of each retinal layer were measured, and electroretinogram were performed together with fundus fluorescein angiography and optical coherence tomography. The levels of inflammatory factors were examined in retinal tissue, as well as those of intercellular adhesion molecule 1 (ICAM-1), IL-6, and monocyte chemoattractant protein 1 (MCP-1) in the serum using ELISA. Immunohistochemistry was used to evaluate levels of vascular endothelial growth factor (VEGF), B-cell lymphoma 2 (Bcl-2), and Bclassociated X protein (Bax). Retinal cell injury and apoptosis were examined by TdT-mediated dUTP Nick End Labeling (TUNEL) assays. Results: The data showed that CDDP significantly improved cellular disarrangement. Imaging data indicated that CDDP could reduce vascular permeability and the amplitude of oscillatory potentials (OPs), and restore the thickness of the ganglion cell layer. Moreover, CDDP reduced the expression levels of inflammatory factors in both the retina and serum. Conclusion: These findings strongly suggest that CDDP prevents early DR through vascular and neuroprotection."

Diabetic macular edema (DME) is an ocular complication in patients with diabetes, and it can impair vision significantly. DME is a disorder of the neurovascular system, and it causes obstructions of the retinal capillaries, damage of the blood vessels, and hyperpermeability due to the expression and action of vascular endothelial growth factor (VEGF). These changes result in hemorrhages and leakages of the serous components of blood that result in failures of the neurovascular units (NVUs). Persistent edema of the retina around the macula causes damage to the neural cells that constitute the NVUs resulting in diabetic neuropathy of the retina and a reduction in vision quality. The macular edema and NVU disorders can be monitored by optical coherence tomography (OCT). Neuronal cell death and axonal degeneration are irreversible, and their development can result in permanent visual loss. Treating the edema before these changes are detected in the OCT images is necessary for neuroprotection and maintenance of good vision. This review describes the effective treatments for the macular edema that are therefore neuroprotective."

Seventeen human donor retinas were classified as diabetes mellitus (DM, n = 7), diabetes with diabetic retinopathy (DR, n = 3), or control (n = 8). Macular transversal sections were analyzed for photoreceptors, bipolar cells, horizontal cells, ganglion cells, their synaptic connections, and M\u00fcller cells using immunohistochemistry and confocal microscopy. The densities of bipolar cells, horizontal cells, and ganglion cells and the thickness of the inner plexiform layer (IPL) were quantified around the fovea. In the macula, cone photoreceptors elongated their axons to establish synapses with bipolar and horizontal cells in intraretinal cysts. Bipolar cells were reduced in the DM group compared to the control (P < 0.001), and rod bipolar cells showed morphological alterations in the cell body and synaptic terminals in both diabetic groups. Morphological changes were observed in both plexiform layers, with a decrease in the IPL thickness in DR. Horizontal cell terminals sprouted into the outer and inner retina in DR, despite no density differences existing between DM and control (P = 0.498). Ganglion cell density was reduced in the DM retinas compared to control (P < 0.001). M\u00fcller cells exhibited thickening of their cell bodies and end feet in all diabetic retinas. The degeneration of neurons and synaptic connectivity within the macula in individuals with DM, even in the absence of clinical vascular signs, is associated with impaired visual function. These early changes suggest potential new biomarkers for imaging techniques and emphasize the need for therapies for diabetic patients without clinical signs."

A cross-sectional prospective pilot study was conducted on two groups. We compared the results of functional tests (Pattern ERG and Pattern VEP - PERG and PVEP) and anatomical tests (macular and RNFL OCT) in a diabetic group without diabetic retinopathy to a control group. The \u03c72 test was used to study qualitative data, and the t test was used for quantitative data. The significance threshold was a P value less than 0.05. A total of 37 eyes were included in the study. None of the demographic variables showed any significant association or effect on any of the two groups. GCL thickness was significantly reduced in the diabetic group in the superior, inferior, and nasal outer circles, with a P value <0.001. The amplitude of the P100 wave was significantly reduced in the diabetic group, with a P value<0.05 for the pattern sizes of 60' and 30', and the diabetic group had a longer latency for the 15' VEPs.

Their pathogenesis is intricately linked to oxidative stress-induced dysfunction of retinal pigment epithelial (RPE) cells and subsequent retinal degeneration. Macroautophagy/autophagy, a critical cellular degradation pathway, plays a vital role in maintaining RPE homeostasis, yet its dysregulation in retinal degenerative diseases remains poorly understood. In this study, we observed that sodium iodate (NaIO3), an oxidative stress inducer, triggered lysosomal dysfunction via lysosomal membrane permeabilization (LMP), thereby impairing autophagic flux in RPE cells and exacerbating retinal degeneration. RNA sequencing identified LAMP3 (lysosomal-associated membrane protein 3) as a downregulated gene following NaIO3 treatment. Functionally, LAMP3 overexpression alleviated NaIO3-induced LMP, improved lysosomal function, and alleviated autophagic impairment. Furthermore, upregulation of LAMP3 reduced oxidative stress and apoptosis in RPE cells, while alleviating retinal degeneration in a NaIO3-induced mouse model. Mechanistically, our data suggested that NaIO3 upregulated the transcription factor SNAI1, which acts as a transcriptional repressor of LAMP3. SNAI1 knockdown increased LAMP3 expression, thereby facilitating the recovery of lysosomal function and the alleviation of autophagic impairment. Collectively, our findings indicate that the SNAI1-LAMP3 axis contributes to the regulation of the autophagy-lysosomal pathway in retinal degeneration, highlighting a potential therapeutic target for delaying disease progression.Abbreviations: AMD: age-related macular degeneration; AO: acridine orange; Baf A1: bafilomycin A1; BAX: BCL2-associated X protein; BCL2: B cell leukemia/lymphoma 2; BSA: bovine serum albumin; CCK-8: cell counting kit-8; ChIP: chromatin immunoprecipitation; CM-H2DCFDA: chloromethyl-2',7'-dichlorodihydrofluorescein diacetate; CTSD: cathepsin D; DAPI: 4',6-diamidino-2-phenylindole; DEGs: differentially expressed genes; DHE: dihydroethidium; EdU: 5-ethynyl-2'-deoxyuridine; ERG: electroretinography; GSEA: gene set enrichment analysis; H&E: hematoxylin and eosin; HsRPE: human primary retinal pigment epithelial; JC-1: 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolylcarbocyanine iodide; LAMP1: lysosomal-associated membrane protein 1; LAMP2: lysosomal-associated membrane protein 2; LAMP3: lysosomal-associated membrane protein 3; LGALS3: lectin, galactose binding, soluble 3; LLOMe: leu-leu methyl ester; LMP: lysosomal membrane permeabilization; MAP1LC3B/LC3B: microtubule-associated protein 1 light chain 3 beta; MMP: mitochondrial membrane potential; NAC: N-acetyl-L-cysteine; NaIO3: sodium iodte; NC: negative control; OCT: optical coherence tomography; PCA: principal component analysis; PI: propidium iodide; qRT-PCR: quantitative real-time polymerase chain reaction; Rapa: rapamycin; ROS: reactive oxygen species; RP: retinitis pigmentosa; RPE: retinal pigment epithelium; RPE65: retinal pigment epithelium 65; siRNA: small interfering RNA; SNAI1: snail family zinc finger 1; SQSTM1/p62: sequestosome 1; TJP1/ZO-1: tight junction protein 1; ZNF135: zinc finger protein 135."

While the most common inherited retinal diseases (IRDs) involve defects in rod and/or cone function, another group (referred to as congenital stationary night blindness (CSNB)) results from defects in glutamate release from photoreceptors, or conversion of the glutamatergic signal in bipolar cells. One example results from mutations in the CACNA2D4 gene, which encodes a subunit of the voltage-gated calcium channel that is critical for glutamate release from both rod and cone photoreceptors. Mutations in CACNA2D4 result in a range of phenotypes in human patients, from incomplete CSNB to rod-cone dystrophy. In the CACNA2D4 knockout mouse ( \u03b12\u03b44 -/- ), there is slow photoreceptor degeneration, the photoreceptor-to-bipolar cell synapse is disorganized, and the retina lacks scotopic and photopic full-field electroretinogram b-waves; this also results in low visual acuity. Using adult \u03b12\u03b44 -/- mice, we show that recombinant adeno-associated virus (rAAV)-mediated gene therapy directed to rod photoreceptors prevents rod degeneration, restores synaptic organization, retinal function, and improves visual acuity under both light- and dark-adapted conditions. This rescue was maintained for up to 14 months post-treatment. Together, our results demonstrate that synaptic structure and function can be restored in the mature mouse retina in a model of complete synaptic disorganization. The results highlight the neuroprotective potential of targeting synaptic organizing proteins in retinal gene therapy."

Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy."

Within the RNVU, calcium ions coordinate neurotransmission, glial activation, vascular tone, and blood-retinal barrier maintenance, and calcium dysregulation is emerging as a unifying pathogenic hub across these conditions. Although upstream triggers differ, including mechanical stress in glaucoma, hyperglycemia in DR, oxidative damage in AMD, ischemic energy failure in RIR, and amyloid-\u03b2-driven endoplasmic reticulum stress in AD, all converge on disruption of intracellular calcium homeostasis, producing shared downstream consequences including excitotoxic injury of retinal ganglion cells (RGCs), M\u00fcller cell reactive gliosis, and pericyte hypercontraction.

Acarbose (ACA), an \u03b1-glucosidase inhibitor widely used for diabetes, has recently been recognized for its dual regulatory potential on immune metabolism and aging-associated neurodegeneration. Here, we demonstrate that intravitreal ACA administration attenuates retinal inflammation and improves RGCs survival following IR injury. Single-cell RNA sequencing revealed extensive inflammatory activation and metabolic reprogramming across the retina, characterized by enhanced nicotinamide adenine dinucleotide (NAD) catabolism, particularly in microglia. ACA treatment was associated with reversal of these alterations, replenished NAD levels, and restored mitochondrial integrity. Integrative proteomic and biochemical analyses identified pyruvate kinase, muscle-type 2 (Pkm2) as a candidate regulatory node affected by ACA. Intravitreal delivery of siPkm2 partially protected against IR injury, and co-administration with ACA produced an additive trend in neuroprotection. Mechanistically, ACA upregulated sirtuin 1 (Sirt1) and reduced Pkm2 acetylation at lysine 270 (K270), which was linked to pro-inflammatory microglial activation. Structure-based virtual screening further identified HY-113082, a small molecule targeting Pkm2-K270, which synergized with ACA to suppress inflammation and enhance retinal protection. Moreover, Pkm2fl/flCx3cr1-Cre mice conferred partial resistance to IR injury, but blunted the additional benefit of HY-113082 when combined with ACA, consistent with on-target engagement. Our findings support that ACA exerts retinal protection through the Sirt1-Pkm2-NAD axis, suggesting a metabolic checkpoint that integrates immune and mitochondrial regulation. This study provides mechanistic insight into ACA's dual immunometabolic and neuroprotective actions, holding promise for therapeutic insights into neuroinflammation."

In this study, we investigated the protective effects of norrin against hyperglycemia-induced retinal neurodegeneration and elucidated its underlying molecular mechanisms in diabetic mice. We found that retinal neurodegeneration may precede microvascular leakage in diabetic retinas. Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Intravitreal supplementation of norrin markedly attenuated hyperglycemia-induced neurodegenerative processes, leading to retinal ganglion cell (RGC) apoptosis, including oxidative stress, inflammation, and neuropathological alterations such as reactive gliosis, glutamate excitotoxicity, and synaptic dysfunction. Norrin also reduced hyperglycemia-induced microvascular leakage and RGC apoptosis by normalizing vascular endothelial growth factor (VEGF) overexpression and restoring pigment epithelium-derived factor (PEDF) levels. Notably, PEDF upregulated by norrin effectively suppressed neurodegenerative processes induced by hyperglycemia or VEGF, thereby preserving RGC function. These findings identify norrin as a critical modulator of hyperglycemia-induced retinal neurodegeneration through restoration of the VEGF-PEDF balance. Our results highlight norrin as a potential therapeutic target for early neurodegenerative changes in diabetic retinopathy."

This study sought to determine the effects of pelargonidin on extracellular matrix (ECM) modulation and the inhibition of transforming growth factor-\u03b2 (TGF-\u03b2) and Janus Kinase 2/Signal Transducer and Activator of Transcription 3 (JAK2/STAT3) pathway in retinal ganglion cells of streptozotocin-induced diabetic rats. Male Sprague-Dawley rats (180-200 g) were rendered diabetic by intraperitoneal administration of streptozotocin (STZ). The rats were divided into 5 groups: control, diabetic model (STZ), STZ + low dose pelargonidin (12.5 mg kg-1 per day), STZ + medium dose pelargonidin (25 mg kg-1 per day) and STZ + high dose pelargonidin (50 mg kg-1 per day). IOP was monitored using a tonometer. Whole-mount retinal immunofluorescence staining using RNA-binding protein with multiple splicing (RBPMS) was performed to assess retinal ganglion cell (RGC) density. Protein expression levels of apoptotic markers, ECM components, and TGF-\u03b2 and JAK2/STAT3 signalling pathways were evaluated by Western blotting. Pelargonidin treatment dose-dependently reduced the elevated IOP. Importantly, immunofluorescence analysis revealed a marked dose-dependent preservation of retinal ganglion cell (RGC) density: STZ-induced RGC loss was significantly reversed by pelargonidin, with the highest dose restoring RGC density to near-control or higher levels in both the central and peripheral retina. This was achieved via modulation of apoptosis-related proteins through the upregulation of Bcl-xL, Bcl-2, and downregulation of Bad, Bax and cleaved caspase-3. Furthermore, pelargonidin modulated ECM remodelling protein expression in the RGC layer. In particular, TGF-\u03b22/Smad2/3 signalling was downregulated, and the JAK2/STAT3 pathway was upregulated. By reducing IOP, preserving RGC density, modulating ECM deposition, inhibiting TGF-\u03b2 and upregulating the JAK2/STAT3 pathway, pelargonidin exerts protective effects against diabetic retinal injury. The results of this study further confirm the pharmacological potential of pelargonidin as a therapeutic agent for diabetic retinopathy."

This review examines the complex structural, functional, and molecular differences in NMJs that innervate fast- and slow-twitch skeletal muscle fibers. Fast-twitch fibers, optimized for rapid and powerful contractions, possess elaborate NMJs with deep folds, high neurotransmitter turnover, and greater vulnerability to synaptic fatigue and degeneration. In contrast, slow-twitch fiber NMJs exhibit simpler but more stable architectures that support sustained, fatigue-resistant activity. These differences are not fixed but subject to activity-dependent plasticity and pathological remodeling. Chronic stimulation, injury, and aging influence NMJ morphology, with fast-twitch junctions more prone to degeneration in conditions such as ALS, myasthenia gravis, and diabetic neuropathy. Slow-twitch NMJs often resist early deterioration due to superior trophic support, metabolic stability, and more robust expression of synaptic organizers, such as agrin and PGC-1\u03b1. Several key signaling pathways, including agrin-MuSK-LRP4, Wnt/\u03b2-catenin, and neuregulin/ErbB, govern NMJ maintenance with fiber-type-specific nuances. These insights underscore the importance of tailoring therapeutic strategies to the muscle fiber phenotype. Gene therapies, neuromuscular electrical stimulation, and biomaterial scaffolds are emerging as promising modalities for preserving or restoring NMJ integrity, especially in fast-twitch fibers at higher risk of degeneration. Understanding fiber-type-specific NMJ biology enhances our understanding of motor control, muscle aging, and neuromuscular disease progression, and it opens pathways for precision therapeutics that target vulnerable synapses with structural and functional specificity. This review introduces a novel perspective by emphasizing fiber-type-specific NMJ differences and their implications for targeted therapies."

Retinal inflammation and angiogenesis contribute largely to the neuronal degeneration in DIR. The current study is aiming to test the effect of oral betanin doses in protection from DIR in rats along with a network pharmacology study to investigate an assumption that betanin may inhibit nuclear factor-\u03ba B (NF-\u03baB). Three rat groups were assigned as vehicle, DIR, and DIR\u00a0+\u00a0Betanin 100\u00a0mg/kg. Molecular docking indicated the possible binding between betanin and NF-\u03baB while the bioinformatic study highlighted a relation between this possible inhibition and suppression of NOD-like receptor pyrin domain-containing protein 3/vascular endothelial growth factor (NLRP3/VEGF) axis. The rat experimental study validated this assumption and indicated a protective effect for betanin on rat retinas as shown by routine hematoxylin and eosin staining (retinal thickness and ganglion cell count) and periodic acid-Schiff staining that was mediated through mitigating expression/protein level for of NF-\u03baB, NLRP3, TNF-\u03b1, IL-6 and VEGF proteins. Immunohistochemistry showed that betanin was able to suppress retinal content of the glial fibrillary acidic protein (GFAP). In conclusion, the current study indicated that betanin was a good candidate for DIR in rats through suppression of the inflammatory cascade and may be suggested for diabetic patients if appropriated clinical studies will be available."

Evidence suggests that additional vascular and neurodegenerative mechanisms may be involved. This study aimed to characterise the thickness of the Ganglion Cell Complex (GCC) and investigate the Choroidal Vascularity Index (CVI) in patients with different patterns of therapeutic response to AVEGF DME. This cross-sectional study included 27 diabetic patients into 3 different groups based on their response to AVEGF therapy: control group, responder DME group, and persistent DME group. The study's approach to vascular and neurodegenerative imaging biomarkers involved three steps: (1) Automatic quantification of GCC thickness, with manual correction when necessary; (2) Semi-automatic measurement of choroidal thickness; and (3) Analysis of choroidal area and choroidal luminal area using ImageJ software to calculate the CVI. In the overall characterization of the sample, a significant difference was observed only in the Best Corrected Visual Acuity (BCVA). There was a significant difference in Average Retinal Thickness (1\u00a0mm, 3\u00a0mm, and 6\u00a0mm) between the 3 groups and in GCC thickness at 1\u00a0mm. BCVA was negatively correlated with mean retinal thickness, while CVI showed a potential positive correlation with BCVA. While demographic and general clinical characteristics showed minimal differences across the groups, important differences in GCC and choroidal characteristics were observed. GCC (1\u00a0mm) may be interesting to explore in predicting visual outcomes after treatment, and CVI may impact visual gain."

Links between established changes in the morphology of retinal ganglion cells (RGCs) and vision loss, as well as other functions, such as the pupillary light reflex, are considered. RGC morphology and function are significantly altered in both animal models and humans with diabetes. Diabetes affects all parts of the RGC, including the dendrites, the cell body, the axons making up the nerve fiber layer, and the optic nerve. Subtypes of RGCs appear to be affected differently by diabetes, and the morphology and electrophysiological output are more significantly affected in ON-RGCs than in OFF cells, which may explain part of the mechanism underlying the widely documented diabetes-induced reduction in contrast sensitivity. Furthermore, the morphology of the specialized light-sensitive melanopsin-containing RGCs also appears to be affected by diabetes, which may explain deficits in circadian rhythm and the pupillary light reflex. Potential therapeutic approaches aimed at protecting RGCs in diabetes are also discussed. Overall, strong evidence supports the conclusion that diabetes impacts the form and function of RGCs and their axons within the optic nerve, resulting in deficient regulation of circadian rhythms and the pupillary light reflex, in addition to vision."

Studies, including our own, demonstrate that SRR is linked to a complication of diabetes, diabetic retinopathy (DR), and deletion of Srr protects diabetic animals from developing retinopathy. We investigate the feasibility and mechanisms of SRR inhibition as a strategy to prevent DR. SRR proteins in the retinas of db/db mice were approximately 50\u00a0% higher than C57BLKS/J wild-type (WT) mice, while D-serine levels in the aqueous humor were more than two-fold higher. Oral gavage of l-aspartic acid \u03b2-hydroxamate (L-ABH) improved b-wave amplitudes in electroretinogram recordings under both photopic and scotopic conditions. It also protected the inner retina in db/db mice by reducing the loss of retinal ganglion cells, endothelial cells, and pericytes, as well as decreasing the activation of M\u00fcller cells. In high glucose and hypoxia, interleukin-1 and interleukin-18 mRNA levels were lower in Srr-deleted M\u00fcller cell cultures than in WT cultures.

Altogether, our results demonstrate that SRR inhibition prevents retinopathy in diabetic animals by blocking excitotoxicity and M\u00fcller cell-mediated inflammation in the retina, while also maintaining glucose homeostasis. This is the first demonstration that pharmacological blockade of SRR improves retinopathy and normalizes glucose levels in a type 2 diabetes model."

Prospective observational cohort study. T2DM patients without clinical retinopathy at baseline and after a 2-year follow-up, along with age- and sex-matched healthy controls, were recruited from the community in Guangzhou, China. Measurements of macular GCIPLT, retinal thickness (RT), and SCP vessel density were conducted at baseline and at the 2-year follow-up. Linear mixed-effects models were used to estimate absolute and relative rates of changes and to compare absolute rates between the 2 groups. A total of 282 eyes (141 in the control group and 141 in the non-DR group) were included in the analysis. Significant reductions in GCIPLT and GCIPLT/RT occurred only in the non-DR group, with GCIPLT decreasing by -0.229 \u00b5m/y (95% CI = -0.313 to -0.144; P < .001) and 0.324 % (95% CI = 0.444 to 0.204; P < .001), approximately 5-fold faster than in the control group.

In this study, we investigated the neuronal RNA-binding protein HuD as a novel regulator of neuro-retinal degeneration in the early stage of diabetes. We determined the expression of HuD and alpha-crystallin A (CRYAA) in the retinal ganglion cell layer. HuD and CRYAA were down-regulated in the retinas of streptozotocin-induced diabetic rats and in neuro-retinal cells (R-28) treated with high glucose.

DJ-1 (PARK7) acts as a crucial antioxidant defense mechanism, stabilizing mitochondrial structure and redox balance. However, its expression is dramatically suppressed under diabetic conditions, and the upstream regulatory mechanisms remain incompletely characterized. Growing evidence from epigenetic research implicates microRNAs (miRNAs) as important players in the molecular pathways underlying DR progression. Among these, miRNA-122-5p has drawn increasing attention due to its aberrant activity under diabetic stress and its putative interaction with PARK7. In this study, we employed a streptozotocin-induced type 1 diabetes mouse model and glucose-stimulated R28\u00a0cells to explore the contribution of miRNA-122-5p to mitochondrial damage, oxidative stress, and RGC injury. In diabetic mice, we observed significant oxidative imbalance, increased apoptotic activity, RGC loss, and diminished retinal function. MiRNA profiling identified miRNA-122-5p as the most upregulated among candidate miRNAs. Inhibition of miRNA-122-5p attenuated these pathological changes and preserved both cellular integrity and visual function. In vitro, high glucose triggered mitochondrial fragmentation, membrane potential collapse, and excessive reactive oxygen species generation in R28\u00a0cells. Suppressing miRNA-122-5p alleviated these injuries. Dual-luciferase assays confirmed that miRNA-122-5p directly targets PARK7, thereby post-transcriptionally repressing DJ-1 expression and compromising mitochondrial resilience. These findings establish miRNA-122-5p as a critical upstream regulator of DJ-1-mediated antioxidant defense. By aggravating mitochondrial oxidative stress, it contributes to RGC vulnerability in DR. Targeted modulation of miRNA-122-5p may offer a novel therapeutic approach to preserve retinal neurons and counteract neurodegeneration in DR."

At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy."

Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment."

Within the RNVU, calcium ions coordinate neurotransmission, glial activation, vascular tone, and blood-retinal barrier maintenance, and calcium dysregulation is emerging as a unifying pathogenic hub across these conditions. Although upstream triggers differ, including mechanical stress in glaucoma, hyperglycemia in DR, oxidative damage in AMD, ischemic energy failure in RIR, and amyloid-\u03b2-driven endoplasmic reticulum stress in AD, all converge on disruption of intracellular calcium homeostasis, producing shared downstream consequences including excitotoxic injury of retinal ganglion cells (RGCs), M\u00fcller cell reactive gliosis, and pericyte hypercontraction. Broad-spectrum calcium channel blockade has shown limited clinical success, underscoring the need for cell-type-specific and pathway-selective approaches. This review therefore catalogs key interventional nodes, including transient receptor potential (TRP) channel antagonists, T-type calcium channel inhibitors, calcium/calmodulin-dependent protein kinase II (CaMKII) suppressors, and mitochondrial permeability transition pore (mPTP) inhibitors, and discusses how precision targeting of these pathways may restore RNVU homeostasis and open a therapeutic window into central nervous system (CNS) degenerative disorders."

Acarbose (ACA), an \u03b1-glucosidase inhibitor widely used for diabetes, has recently been recognized for its dual regulatory potential on immune metabolism and aging-associated neurodegeneration. Here, we demonstrate that intravitreal ACA administration attenuates retinal inflammation and improves RGCs survival following IR injury. Single-cell RNA sequencing revealed extensive inflammatory activation and metabolic reprogramming across the retina, characterized by enhanced nicotinamide adenine dinucleotide (NAD) catabolism, particularly in microglia. ACA treatment was associated with reversal of these alterations, replenished NAD levels, and restored mitochondrial integrity. Integrative proteomic and biochemical analyses identified pyruvate kinase, muscle-type 2 (Pkm2) as a candidate regulatory node affected by ACA. Intravitreal delivery of siPkm2 partially protected against IR injury, and co-administration with ACA produced an additive trend in neuroprotection. Mechanistically, ACA upregulated sirtuin 1 (Sirt1) and reduced Pkm2 acetylation at lysine 270 (K270), which was linked to pro-inflammatory microglial activation. Structure-based virtual screening further identified HY-113082, a small molecule targeting Pkm2-K270, which synergized with ACA to suppress inflammation and enhance retinal protection. Moreover, Pkm2fl/flCx3cr1-Cre mice conferred partial resistance to IR injury, but blunted the additional benefit of HY-113082 when combined with ACA, consistent with on-target engagement. Our findings support that ACA exerts retinal protection through the Sirt1-Pkm2-NAD axis, suggesting a metabolic checkpoint that integrates immune and mitochondrial regulation. This study provides mechanistic insight into ACA's dual immunometabolic and neuroprotective actions, holding promise for therapeutic insights into neuroinflammation."

In this study, we investigated the protective effects of norrin against hyperglycemia-induced retinal neurodegeneration and elucidated its underlying molecular mechanisms in diabetic mice. We found that retinal neurodegeneration may precede microvascular leakage in diabetic retinas. Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Intravitreal supplementation of norrin markedly attenuated hyperglycemia-induced neurodegenerative processes, leading to retinal ganglion cell (RGC) apoptosis, including oxidative stress, inflammation, and neuropathological alterations such as reactive gliosis, glutamate excitotoxicity, and synaptic dysfunction. Norrin also reduced hyperglycemia-induced microvascular leakage and RGC apoptosis by normalizing vascular endothelial growth factor (VEGF) overexpression and restoring pigment epithelium-derived factor (PEDF) levels. Notably, PEDF upregulated by norrin effectively suppressed neurodegenerative processes induced by hyperglycemia or VEGF, thereby preserving RGC function. These findings identify norrin as a critical modulator of hyperglycemia-induced retinal neurodegeneration through restoration of the VEGF-PEDF balance. Our results highlight norrin as a potential therapeutic target for early neurodegenerative changes in diabetic retinopathy."

This study sought to determine the effects of pelargonidin on extracellular matrix (ECM) modulation and the inhibition of transforming growth factor-\u03b2 (TGF-\u03b2) and Janus Kinase 2/Signal Transducer and Activator of Transcription 3 (JAK2/STAT3) pathway in retinal ganglion cells of streptozotocin-induced diabetic rats. Male Sprague-Dawley rats (180-200 g) were rendered diabetic by intraperitoneal administration of streptozotocin (STZ). The rats were divided into 5 groups: control, diabetic model (STZ), STZ + low dose pelargonidin (12.5 mg kg-1 per day), STZ + medium dose pelargonidin (25 mg kg-1 per day) and STZ + high dose pelargonidin (50 mg kg-1 per day). IOP was monitored using a tonometer. Whole-mount retinal immunofluorescence staining using RNA-binding protein with multiple splicing (RBPMS) was performed to assess retinal ganglion cell (RGC) density. Protein expression levels of apoptotic markers, ECM components, and TGF-\u03b2 and JAK2/STAT3 signalling pathways were evaluated by Western blotting. Pelargonidin treatment dose-dependently reduced the elevated IOP. Importantly, immunofluorescence analysis revealed a marked dose-dependent preservation of retinal ganglion cell (RGC) density: STZ-induced RGC loss was significantly reversed by pelargonidin, with the highest dose restoring RGC density to near-control or higher levels in both the central and peripheral retina. This was achieved via modulation of apoptosis-related proteins through the upregulation of Bcl-xL, Bcl-2, and downregulation of Bad, Bax and cleaved caspase-3. Furthermore, pelargonidin modulated ECM remodelling protein expression in the RGC layer. In particular, TGF-\u03b22/Smad2/3 signalling was downregulated, and the JAK2/STAT3 pathway was upregulated. By reducing IOP, preserving RGC density, modulating ECM deposition, inhibiting TGF-\u03b2 and upregulating the JAK2/STAT3 pathway, pelargonidin exerts protective effects against diabetic retinal injury. The results of this study further confirm the pharmacological potential of pelargonidin as a therapeutic agent for diabetic retinopathy."

This review examines the complex structural, functional, and molecular differences in NMJs that innervate fast- and slow-twitch skeletal muscle fibers. Fast-twitch fibers, optimized for rapid and powerful contractions, possess elaborate NMJs with deep folds, high neurotransmitter turnover, and greater vulnerability to synaptic fatigue and degeneration. In contrast, slow-twitch fiber NMJs exhibit simpler but more stable architectures that support sustained, fatigue-resistant activity. These differences are not fixed but subject to activity-dependent plasticity and pathological remodeling. Chronic stimulation, injury, and aging influence NMJ morphology, with fast-twitch junctions more prone to degeneration in conditions such as ALS, myasthenia gravis, and diabetic neuropathy. Slow-twitch NMJs often resist early deterioration due to superior trophic support, metabolic stability, and more robust expression of synaptic organizers, such as agrin and PGC-1\u03b1. Several key signaling pathways, including agrin-MuSK-LRP4, Wnt/\u03b2-catenin, and neuregulin/ErbB, govern NMJ maintenance with fiber-type-specific nuances. These insights underscore the importance of tailoring therapeutic strategies to the muscle fiber phenotype. Gene therapies, neuromuscular electrical stimulation, and biomaterial scaffolds are emerging as promising modalities for preserving or restoring NMJ integrity, especially in fast-twitch fibers at higher risk of degeneration. Understanding fiber-type-specific NMJ biology enhances our understanding of motor control, muscle aging, and neuromuscular disease progression, and it opens pathways for precision therapeutics that target vulnerable synapses with structural and functional specificity. This review introduces a novel perspective by emphasizing fiber-type-specific NMJ differences and their implications for targeted therapies."

Evidence suggests that additional vascular and neurodegenerative mechanisms may be involved. This study aimed to characterise the thickness of the Ganglion Cell Complex (GCC) and investigate the Choroidal Vascularity Index (CVI) in patients with different patterns of therapeutic response to AVEGF DME. This cross-sectional study included 27 diabetic patients into 3 different groups based on their response to AVEGF therapy: control group, responder DME group, and persistent DME group. The study's approach to vascular and neurodegenerative imaging biomarkers involved three steps: (1) Automatic quantification of GCC thickness, with manual correction when necessary; (2) Semi-automatic measurement of choroidal thickness; and (3) Analysis of choroidal area and choroidal luminal area using ImageJ software to calculate the CVI. In the overall characterization of the sample, a significant difference was observed only in the Best Corrected Visual Acuity (BCVA). There was a significant difference in Average Retinal Thickness (1\u00a0mm, 3\u00a0mm, and 6\u00a0mm) between the 3 groups and in GCC thickness at 1\u00a0mm. BCVA was negatively correlated with mean retinal thickness, while CVI showed a potential positive correlation with BCVA. While demographic and general clinical characteristics showed minimal differences across the groups, important differences in GCC and choroidal characteristics were observed. GCC (1\u00a0mm) may be interesting to explore in predicting visual outcomes after treatment, and CVI may impact visual gain."

We investigate the feasibility and mechanisms of SRR inhibition as a strategy to prevent DR. SRR proteins in the retinas of db/db mice were approximately 50\u00a0% higher than C57BLKS/J wild-type (WT) mice, while D-serine levels in the aqueous humor were more than two-fold higher. Oral gavage of l-aspartic acid \u03b2-hydroxamate (L-ABH) improved b-wave amplitudes in electroretinogram recordings under both photopic and scotopic conditions. It also protected the inner retina in db/db mice by reducing the loss of retinal ganglion cells, endothelial cells, and pericytes, as well as decreasing the activation of M\u00fcller cells. In high glucose and hypoxia, interleukin-1 and interleukin-18 mRNA levels were lower in Srr-deleted M\u00fcller cell cultures than in WT cultures.

Systemically, L-ABH maintained euglycemia and improved glucose tolerance in db/db mice by inhibiting liver gluconeogenesis through restricting the expansion of pancreatic islet \u03b1-cells. Altogether, our results demonstrate that SRR inhibition prevents retinopathy in diabetic animals by blocking excitotoxicity and M\u00fcller cell-mediated inflammation in the retina, while also maintaining glucose homeostasis.

Prospective observational cohort study. T2DM patients without clinical retinopathy at baseline and after a 2-year follow-up, along with age- and sex-matched healthy controls, were recruited from the community in Guangzhou, China. Measurements of macular GCIPLT, retinal thickness (RT), and SCP vessel density were conducted at baseline and at the 2-year follow-up. Linear mixed-effects models were used to estimate absolute and relative rates of changes and to compare absolute rates between the 2 groups. A total of 282 eyes (141 in the control group and 141 in the non-DR group) were included in the analysis. Significant reductions in GCIPLT and GCIPLT/RT occurred only in the non-DR group, with GCIPLT decreasing by -0.229 \u00b5m/y (95% CI = -0.313 to -0.144; P < .001) and 0.324 % (95% CI = 0.444 to 0.204; P < .001), approximately 5-fold faster than in the control group.

Elevated intraocular pressure disrupted synapses, as evidenced by reduced synaptophysin expression and homeostatic increases in Bassoon and PSD95 levels in the inner plexiform layer. SPG302 treatment effectively preserved synaptic integrity by reversing these changes. These findings highlight the therapeutic potential of SPG302 for protecting RGCs and preserving vision by modulating synaptic activity in glaucomatous neurodegeneration."

As antibodies are unable to distinguish NRXN family members and isoforms, the purpose of this study was to investigate differential expression of individual NRXN transcripts in relevant retinal cell types in early DRD. RNAscope multiplexed fluorescent in situ hybridization was used to quantify transcripts of NRXNs in mouse and human retina. DM was induced in C57BL/6J mice using streptozotocin (STZ) and the retinal phenotype characterized by electroretinogram (ERG), optical coherence tomography (OCT), and optokinetic tracking (OKT) after 6 weeks. Retinal ganglion cells (RGCs) were generated in vitro by directed differentiation from human embryonic stem cells (hESCs), cultured in normal or high glucose, and NRXN expression assessed by qPCR and Western blot. All NRXN family members (NRXN1, NRXN2, and NRXN3) were enriched in inner retinal neurons in both human and mouse tissue. We identified decreased Nrxn3 transcripts, specifically the Nrxn3\u03b2 isoform, in RGCs of diabetic mice at 6 weeks after STZ treatment. Interestingly, Nrxn3\u03b1 and Nrxn3\u03b2 were differentially expressed in inner retinal layers. Finally, we confirmed decreased Nrxn3\u03b2 expression in hESC-RGCs cultured in high glucose in vitro. Our findings suggest that NRXNs may play cell-type-specific roles in the inner retina and associate decreased Nrxn3\u03b2 expression in RGCs with inner retinal dysfunction in early DRD."

The mechanisms leading to neuro-retinal cell loss before vascular complications manifest in diabetes remain poorly understood. In this study, we investigated the neuronal RNA-binding protein HuD as a novel regulator of neuro-retinal degeneration in the early stage of diabetes. We determined the expression of HuD and alpha-crystallin A (CRYAA) in the retinal ganglion cell layer. HuD and CRYAA were down-regulated in the retinas of streptozotocin-induced diabetic rats and in neuro-retinal cells (R-28) treated with high glucose. Cryaa mRNA was identified as a novel target transcript of HuD, and we demonstrated that HuD post-transcriptionally regulates the expression of Cryaa mRNA by binding to its 3'-untranslated region. Silencing and overexpression of HuD positively regulated the expressions of Cryaa mRNA and protein. We demonstrated that the increase in inflammatory cytokines such as TNF\u03b1, IL-1\u03b2, and IL-6 in R-28 cells under hyperglycemic conditions was a result of both CRYAA and HuD levels. Silencing HuD and CRYAA enhanced high glucose-induced R-28 cell death, whereas their overexpression alleviated this effect. HuD post-transcriptionally regulates CRYAA expression, influencing the function and viability of neuro-retinal cells under diabetic conditions. Our results suggest that the HuD/CRYAA axis plays a crucial role in neuro-retinal cells and has the potential to serve as a prognostic factor and therapeutic target for diabetic neuro-retinal degeneration."

DJ-1 (PARK7) acts as a crucial antioxidant defense mechanism, stabilizing mitochondrial structure and redox balance. However, its expression is dramatically suppressed under diabetic conditions, and the upstream regulatory mechanisms remain incompletely characterized. Growing evidence from epigenetic research implicates microRNAs (miRNAs) as important players in the molecular pathways underlying DR progression. Among these, miRNA-122-5p has drawn increasing attention due to its aberrant activity under diabetic stress and its putative interaction with PARK7. In this study, we employed a streptozotocin-induced type 1 diabetes mouse model and glucose-stimulated R28\u00a0cells to explore the contribution of miRNA-122-5p to mitochondrial damage, oxidative stress, and RGC injury. In diabetic mice, we observed significant oxidative imbalance, increased apoptotic activity, RGC loss, and diminished retinal function. MiRNA profiling identified miRNA-122-5p as the most upregulated among candidate miRNAs. Inhibition of miRNA-122-5p attenuated these pathological changes and preserved both cellular integrity and visual function. In vitro, high glucose triggered mitochondrial fragmentation, membrane potential collapse, and excessive reactive oxygen species generation in R28\u00a0cells. Suppressing miRNA-122-5p alleviated these injuries. Dual-luciferase assays confirmed that miRNA-122-5p directly targets PARK7, thereby post-transcriptionally repressing DJ-1 expression and compromising mitochondrial resilience. These findings establish miRNA-122-5p as a critical upstream regulator of DJ-1-mediated antioxidant defense. By aggravating mitochondrial oxidative stress, it contributes to RGC vulnerability in DR. Targeted modulation of miRNA-122-5p may offer a novel therapeutic approach to preserve retinal neurons and counteract neurodegeneration in DR."

This study investigated whether L-serine supplementation could attenuate DN through dose-dependent metabolic and neuroprotective mechanisms in a high-fat diet (HFD) plus streptozotocin (STZ)-induced diabetic rat model. Male Wistar rats (n = 8 per group) were allocated to five groups: normal control (NC), diabetic control (DC), pioglitazone (PIO; 1.5 mg/kg/day), low-dose L-serine (S1; 200 mg/kg/day), and high-dose L-serine (S2; 400 mg/kg/day). After 60 days of oral gavage, behavioural testing, glucose and insulin profiling, HOMA-IR calculation, brain histopathology, nerve growth factor (NGF) immunohistochemistry, and LC-MS/MS-based proteomic analysis of cerebral tissue were performed. Diabetic rats exhibited marked hyperglycaemia (355.33 \u00b1 4.72 mg/dL), hyperinsulinaemia, severe insulin resistance (HOMA-IR 16.8 \u00b1 3.2; a 14-fold increase), impaired thermal nociception, motor dysfunction, and pronounced neuronal degeneration. L-serine supplementation significantly improved metabolic status: S1 reduced HOMA-IR by 77.4% and S2 by 87.5% relative to diabetic controls (p < 0.001). High-dose L-serine produced greater improvements in thermal sensitivity, motor coordination (rotarod latency 26.67 \u00b1 1.52 s vs. 16.1 \u00b1 0.85 s in DC; p < 0.05), and NGF expression (8.6-fold increase vs. DC). Histopathology confirmed attenuation of neuronal injury and gliosis in both treatment groups. Exploratory, group-level proteomic profiling identified dose-specific molecular signatures: S1 was predominantly associated with carbohydrate, lipid, and biosynthetic pathways, whereas S2 was associated with synaptic, neurotransmission-related, and proteostasis pathways. Within the constraints of an exploratory design-group-level pooled proteomics, analysis of cerebral rather than peripheral-nerve tissue, and only two doses-these findings indicate that L-serine attenuates the metabolic and behavioural features of experimental diabetic neuropathy and generates the testable hypothesis of dose-dependent neuro-metabolic remodelling. The proteomic signatures are hypothesis-generating and require orthogonal validation before any mechanistic or translational inference can be drawn."

Two independent reviewers performed screening, extraction, and the revised Cochrane Risk of Bias tool version 2.0 (RoB 2.0). Random-effects meta-analyses were conducted using the mean differences (MD) with 95% confidence intervals (CI). Five RCTs (n\u2009=\u2009660) met the criteria. Tocotrienol-rich vitamin E increased sural sensory nerve-conduction velocity (NCV) by 1.77\u00a0m s\u207b\u00b9 (0.80-2.74) and median sensory NCV by 1.53\u00a0m s\u207b\u00b9 (0.44-2.63); tibial motor NCV rose 1.47\u00a0m s\u207b\u00b9 (0.36-2.58) versus placebo.

Two trials had a low risk of bias; one presented some concerns. Vitamin E yielded selective NCV gains without amplitude change, suggesting preservation or remyelination of sensory fibers rather than axonal regeneration. The absence of glycemic effects indicates neuroprotection independent of glucose control, positioning vitamin E as a potential adjunct-not substitute-to antidiabetic therapy. Heterogeneity in isoform, dose, and treatment duration (\u2264\u200912 months) and modest sample sizes limit certainty. Larger, longer trials incorporating functional outcomes (pain, gait, and quality of life) are required."

Recent literature supports a shift toward neurovascular unit (NVU) protection, where pharmacological agents like SPG302 target synaptic and mitochondrial integrity. Evidence suggests that preserving retinal ganglion cells (RGCs) and synaptic markers through targeting metabolic pathways (such as Nrf2, AMPK, and nuclear receptors) may prevent progressive visual loss in diabetes and glaucoma.\n\n### [INTRODUCTION & JUSTIFICATION]\nDiabetic retinopathy is no longer classified solely as a microvascular pathology; it is increasingly recognized as a neurovascular degenerative disease involving coordinated injury to the retinal neurovascular unit. Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function, decreased inner retina synaptic markers, and increased reactive gliosis and cell death. The molecular mechanisms driving this include mitochondrial dysfunction, where high glucose flux promotes mitochondrial reactive oxygen species overproduction and oxidative stress. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma, another leading cause of blindness associated with early synapse loss in the retina.

SPG302, a pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and demonstrates neuroprotective potential in both diabetic and glaucomatous models by mitigating inner retinal damage and preserving visual function.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm of diabetic retinopathy has shifted from a primarily microvascular perspective to a neurovascular degenerative disorder where retinal ganglion cell (RGC) integrity and synaptic stability serve as critical therapeutic targets. The provided literature establishes that DRN manifests as inner retinal degeneration with a loss of ganglion cells and a reduction in synaptic markers, such as PSD95 and synaptophysin. SPG302 stands out as a \"synaptogenic small molecule\" that demonstrates broad applicability across neurodegenerative conditions, including glaucoma and diabetes, by reversing synaptic loss. By promoting synaptogenesis, SPG302 preserves retinal structural integrity and functional output as measured by electroretinography. This approach is aligned with the broader understanding that restoring synaptic architecture and metabolic homeostasis is requisite for preventing the irreversible vision loss associated with diabetic and glaucomatous neurodegeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Neurodegeneration, particularly RGC loss and synaptic impairment, often precedes clinical microvascular symptoms in diabetic retinopathy.\n*   SPG302 acts as a synaptogenic agent, capable of mitigating retinal injury across different disease etiologies, including glaucoma.\n*   The synaptic dysfunction in diabetes and glaucoma involves common molecular pathways, such as the modulation of postsynaptic density (PSD) proteins.\n*   Exosomes derived from specific physiological states (like hibernation) have been identified as potential mediators of intrinsic neuroprotection, suggesting novel intercellular signaling pathways.\n*   The use of GLP-1 receptor agonists and traditional Chinese medicines (e.g., Danshen, Ginsenoside Rg1) provides alternative, multi-target strategies for mitigating neuroinflammation in the retina.\n*   Calcium dysregulation acts as a \"unifying pathogenic hub\" for neurovascular unit dysfunction across multiple neurodegenerative diseases.\n*   Targeting the autophagy-lysosomal pathway (e.g., via the SNAI1-LAMP3 axis) represents an emerging therapeutic direction to preserve RPE and retinal neurons.\n*   Metabolic variability (e.g., glucose flux and uric acid levels) significantly influences the rate of ganglion cell thinning in diabetic patients without retinopathy.\n*   Advanced multimodal imaging (e.g., SS-OCTA) allows for the early detection of neurovascular uncoupling, which serves as a biomarker for disease progression.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

SPG302, a pegylated benzothiazole derivative, demonstrates efficacy in promoting glutamatergic synaptogenesis and preserving retinal integrity. This evaluation synthesizes current literature on the impact of diabetes on RGCs, the role of synaptic loss in disease progression, and the therapeutic potential of SPG302 and similar neuroprotective agents.\n\n### [INTRODUCTION & JUSTIFICATION]\nDiabetic retinal neuropathy (DRN) is an early hallmark of diabetic retinopathy that frequently occurs prior to visible microvasculopathy. The pathology involves the loss of RGCs, impaired RGC function, and a significant decrease in inner retinal synaptic markers. Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function. Because loss of glutamatergic synapses contributes to neuronal atrophy, therapeutic interventions targeting synaptic restoration offer a new point for disease mitigation. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma. Studies demonstrate that SPG302 treatment effectively preserved retinal integrity by reversing these changes. \n\nIn both glaucoma and diabetes, RGC vulnerability is driven by metabolic and neurodegenerative processes. Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. In glaucomatous neurodegeneration, synaptic abnormalities are key, and SPG302 treatment effectively preserved synaptic integrity by reversing these changes. Further neuroprotective strategies include the use of norrin to restore PEDF levels, where Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Additionally, mitochondrial homeostasis is critical, as evidenced by studies showing sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   DRN often presents as a neurodegenerative disease manifesting before clinical microvascular damage is visible.\n*   SPG302 promotes glutamatergic synaptogenesis, offering a potential mechanism to restore synaptic connections that are lost early in the disease process.\n*   Mitochondrial transplantation and mitophagy regulation represent emerging frontiers in preserving RGC viability.\n*   Norrin, a protein secreted by M\u00fcller cells, is crucial for Wnt signaling and retinal capillary formation, and its downregulation is a key pathological event in diabetes.\n*   Neuroprotective effects of therapeutics such as fenofibrate, pelargonidin, and UAB126-MP occur via diverse signaling pathways (e.g., RXR agonism) distinct from conventional pressure-lowering.\n*   The integrity of the neurovascular unit is fundamentally tied to synaptic communication, which remains dysregulated following RGC injury.\n*   Emerging gene therapies, such as WFS1 delivery, show promise for genetic-based optic neuropathies.\n*   Advanced imaging and machine learning (e.g., 2.5D CFF module) are improving the precision of diagnostic markers like the Ganglion Cell Complex (GCC).\n*   Dietary and natural compounds, including eucalyptol and L-serine, show evidence for mitigating metabolic features of diabetic neuropathy.\n*   The relationship between systemic metabolic health and retinal neurodegeneration suggests that retinal assessment could serve as a systemic prognostic tool.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment."

Although DR has traditionally been classified as a microvascular complication, it is now increasingly recognized as a neurovascular degenerative disorder involving coordinated injury to neuronal, glial, vascular, and extracellular matrix components of the retinal neurovascular unit (NVU). The NVU provides the structural and functional basis for coupling neuronal activity to local blood flow and for maintaining retinal immune and barrier homeostasis. In diabetes, chronic hyperglycemia, oxidative stress, inflammation, metabolic dysregulation, impaired vascular endothelial growth factor (VEGF)/angiopoietin-Tie (Ang/Tie) signaling, abnormal intercellular communication, and epigenetic memory progressively disrupt the coordinated interactions among NVU components, leading to neurovascular uncoupling. This concept helps explain why retinal functional abnormalities and neurodegenerative changes may precede clinically visible vascular lesions. In this review, we summarize cell-specific NVU alterations and the molecular mechanisms that drive neurovascular uncoupling in DR. We also discuss how this framework may support earlier diagnosis, mechanism-based phenotyping, and stage-adapted treatment strategies. Established therapies, including anti-vascular endothelial growth factor (anti-VEGF) agents, corticosteroids, and angiopoietin-2 (Ang-2)/Tie-2-directed vascular stabilization, are considered together with investigational approaches targeting oxidative stress, inflammation, neuroprotection, metabolic reprogramming, epigenetic regulation, and drug delivery. Reframing DR as a diabetes-driven disorder of early NVU uncoupling may help shift clinical thinking from late vascular rescue toward mechanism-based neurovascular protection, precision phenotyping, and stage-adapted intervention."

Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy."

Emerging evidence indicates that PANoptosis, an integrated inflammatory programmed cell death modality encompassing apoptosis, pyroptosis, and necroptosis, participates in the progression of diabetic retinal damage; however, the supporting evidence varies substantially across clinical specimens, diabetic animal models, high-glucose cultured retinal cells, and non-DR inflammatory disease models. This review systematically summarizes the latest advances in PANoptosis-associated mechanisms underlying DR pathogenesis, focusing on PANoptosome signaling networks, non-coding RNA-mediated regulation, and immune-metabolic crosstalk. We outline promising candidate biomarkers including PANoptosis-related gene signatures and inflammatory cell death molecules, and critically evaluate multiple translational therapeutic strategies covering small-molecule inhibitors, gene intervention, and nanomedicine delivery. Importantly, we further address context-dependent dual roles of PANoptosis, potential safety risks of non-selective PANoptosis blockade, challenges in blood-retinal barrier penetration, systemic immune side effects, and pathological heterogeneity among DR subtypes and disease stages. Since PANoptosis also fundamentally contributes to host defense and retinal innate immune homeostasis, DR therapeutic strategies should prioritize biomarker-guided, local ocular delivery, time-dependent stage intervention, and cell-type-specific fine tuning, rather than generalized systemic suppression. By reconciling mechanistic progress with unresolved translational bottlenecks, this review proposes that PANoptosis serves as a dynamic and evolving conceptual framework for interpreting inflammatory neurovascular degeneration in DR, instead of an entirely confirmed clinical therapeutic target. We emphasize the urgent need for DR-specific mechanistic verification, longitudinal biomarker cohort studies, and well-designed multicenter clinical trials to advance safe and precise targeted interventions."

We investigated the role of microglial protein-tyrosine phosphatase 1B (PTP1B) as a potential driver of neuropathology in chronic toxoplasmosis. Using a murine model, we demonstrate that PTP1B expression is elevated in the hippocampus following infection. Global genetic ablation or pharmacological inhibition of PTP1B rescued infection-induced cognitive deficits and mitigated neuroinflammation. Crucially, microglia-specific deletion of Ptp1b prevented synaptic loss and cognitive impairment. Mechanistically, we show that microglial PTP1B potentiates the nuclear factor-kappa B (NF-\u03baB) pathway, promoting complement component 1q (C1q)-mediated synaptic tagging and subsequent neuronal structural damage. Validating the clinical relevance of these findings, we observed significantly elevated PTP1B levels in peripheral blood mononuclear cells from T. gondii-seropositive individuals, which correlated with inflammatory markers. Overall, our findings identify microglial PTP1B as a pivotal mediator of T. gondii-associated neurodegeneration."

Because the retina and kidney share similar microvascular architecture, renal dysfunction-routinely expressed as the estimated glomerular filtration rate (eGFR)-is biologically plausible as a marker of DR risk. However, the relationship between eGFR and DR remains controversial. This study aimed to investigate the association between eGFR and DR prevalence in diabetic patients with type 2 diabetes mellitus. This study represents a secondary analysis of data derived from a cross-sectional study. We included 2001 adults with diabetes mellitus (858 men and 1143 women; mean age 64.0\u2009\u00b1\u200911.3 years) who attended the internal-medicine outpatient clinics of two hospitals in southern Taiwan between April 2002 and November 2004. Demographic and clinical variables were recorded, and eGFR was calculated using the simplified MDRD equation. The association between eGFR and DR was examined with multivariable logistic regression, adjusting for potential confounders. To explore potential non-linear relationships, we further applied a generalized additive model (GAM) with smooth-spline fitting. Higher eGFR was inversely associated with the odds of DR across progressively adjusted models. When modeled as a continuous variable, higher eGFR was linked to lower DR odds in Model 1 (OR 0.88; 95% CI 0.83-0.92; P\u2009<\u20090.0001), Model 2 (OR 0.90; 95% CI 0.85-0.95; P\u2009<\u20090.0001), and remained significant after full adjustment in Model 3 (OR 0.92; 95% CI 0.87-0.98; P\u2009=\u20090.0056), indicating a robust inverse association. Compared with the lowest eGFR tertile (15.36-60.50 mL/min/1.73 m2), the highest tertile (76.68-141.22 mL/min/1.73 m2) showed a 30% lower risk of DR (adjusted OR 0.70, 95% CI 0.50-0.90). Smooth-spline analysis confirmed a linear inverse relationship, and no significant effect modification was observed across subgroups of age, sex, BMI, blood pressure, glycaemic control or cardiovascular comorbidities. This cross-sectional analysis demonstrates a clear dose-response pattern: each incremental increase in estimated glomerular filtration rate (eGFR) is associated with a proportional reduction in the likelihood of diabetic retinopathy among adults with type 2 diabetes mellitus. Future work should dissect the shared microvascular pathways linking the kidney and retina and determine whether interventions that preserve renal function can translate into meaningful reductions in retinopathy risk."

Nevertheless, the regulatory mechanism by which Mel modulates mGluR1/glutamate signaling in retinal ischemia-reperfusion (I/R) injury and its downstream effects on ferroptosis and oxidative stress remain poorly understood. Here, bulk RNA sequencing identified that the Mel receptors Mt1/Mt2 and ferroptosis/iron-redox regulators (Gpx4, Fth1, and xCT) were significantly downregulated after retinal I/R. Mel improved retinal structural and visual function, visual-guidance behavior, and electrophysiological responses following I/R while concurrently reducing ferroptotic and inflammatory injury markers. These benefits were largely abolished by Mel membrane receptor antagonists. Mechanistically, Mel upregulated Homer1a in vivo and in vitro in a receptor-dependent manner. Conditional deletion of Homer1a in transgenic mice, as well as Homer1a knockdown in retinal ganglion cells (RGCs), abolished the protective effects of Mel on visual function, along with its anti-ferroptotic and anti-inflammatory activities. Molecular docking and immunoprecipitation assays demonstrated that Mel restored the interaction between Homer1a and mGluR1 and activated the xCT/GSH/Gpx4 antioxidant axis. Pharmacologic inhibition of xCT with the buthionine sulfoximine (BSO) simulation pr genetic interference with xCT expression counteracted the protective effects of Mel. Mel also enhanced Nrf2-mediated transcriptional expression of cCT in a Homer1a/mGluR1-dependent manner. Collectively, our results define a Mel-Homer1a/mGluR1-Nrf2/xCT signaling cascade that promotes RGCs survival after I/R by suppressing ferroptosis/iron-redox reactions, thereby providing a potential translatable strategy for receptor-targeted intervention in I/R-related retinal damage."

This retrospective observational cohort study analyzed data from a prospectively designed treatment outcomes registry. We described outcomes separately in treatment-naive eyes and eyes previously treated with macular thermal laser photocoagulation, all of which received intravitreal aflibercept 2\u00a0mg for DME in routine clinical practice. Given the small number of eyes with prior macular laser, findings in this subgroup were considered descriptive and exploratory. The main functional outcome was change in visual acuity (VA) from baseline at 6, 12, and 24\u00a0months. The main anatomical outcome was change in central subfield thickness (CST) from baseline at the same time points. Secondary outcomes were injection and visit burden, changes in center-involving clinically significant macular edema activity, time to additional macular laser treatment, and ocular adverse events. The cohort included 122 eyes from 78 patients: 110 treatment-naive eyes and 12 eyes with prior macular laser. In treatment-naive eyes, mean VA improved from baseline by 5.5, 5.0, and 5.5 letters at 6, 12, and 24\u00a0months, respectively. Mean CST decreased by 105.9\u00a0\u00b5m, 90.4\u00a0\u00b5m, and 97.1\u00a0\u00b5m, respectively. In eyes with prior macular laser, changes in VA were not statistically significant at any follow-up point. CST decreased significantly at 6\u00a0months (-36.5\u00a0\u00b5m) and 12\u00a0months (-37.5\u00a0\u00b5m), but not at 24\u00a0months (-26.1\u00a0\u00b5m). By month 24, the median number of injections was 12 in treatment-naive eyes and 11 in eyes with prior macular laser. Additional macular laser was rarely needed, and ocular adverse events were rare. In routine clinical care, intravitreal aflibercept 2\u00a0mg for DME was associated with sustained anatomical improvement and modest, largely stable visual gains over 24\u00a0months, particularly in treatment-naive eyes. These findings support favorable real-world outcomes with aflibercept, although subgroup findings in eyes with prior macular laser should be interpreted cautiously."

Optical coherence tomography angiography (OCTA) quantifies retinal perfusion, but its prognostic value in referable DR is not fully established. We aimed to validate baseline deep capillary plexus (DCP) OCTA metrics for predicting one-year complications in eyes with referable DR. In this prospective longitudinal study in 137 eyes of 96 participants, we assessed baseline predictors of DR complications, defined as best-corrected visual acuity (BCVA) loss (\u2265 10 letters on the ETDRS chart), center-involving diabetic macular edema, anti-VEGF injections, pan-retinal photocoagulation, or vitreous hemorrhage. Baseline variables included BCVA, low-luminance visual acuity (LLVA), ocular parameters, demographic characteristics, systemic variables, and OCTA metrics (foveal avascular zone area, vessel density [VD] and geometric perfusion deficit in the superficial capillary plexuses [SCP] and [DCP]). Logistic regression prioritized variables with pathophysiologic relevance while minimizing risk of collinearity. Receiver operating characteristic (ROC) curves assessed whether DCP OCTA metrics improved discrimination beyond a clinical model with traditional risk factors. Over one year, 34 eyes (24.8%) experienced one or more complications. Multivariate analysis including DR severity, DCP VD, and LLVA identified higher baseline DR severity (OR, 5.77; 95% CI: 1.93 to 17.27; P = 0.002) and lower DCP VD (OR, 0.59; 95% CI: 0.36 to 0.95; P = 0.031) as significant predictors. Adding DCP VD to the clinical model significantly improved discrimination. These findings support DCP OCTA metrics as capillary-level biomarkers for risk stratification in referable DR and highlight the need for larger longitudinal studies to confirm clinical utility."

Methods: The experimental study was conducted from February 2024 to October 2025. A chronic ocular hypertension glaucoma model was established by injecting micro-magnetic beads into the anterior chamber of 8- to 10-week-old male Wistar rats. At 3 days, 1 week, and 2 weeks post-modeling, retinal and optic nerve tissues from 6 eyes of 6 rats were collected as the chronic ocular hypertension glaucoma model group, and 6 eyes from 6 wild-type rats that received an equal volume of saline via anterior chamber injection served as the control group. Intraocular pressure was measured using a TonoLab tonometer. Retinal whole-mounts were prepared and POU domain class 4 transcription factor 1 (POU4F1 or Brn3A) immunofluorescence staining was used to detect retinal ganglion cell loss. Western blotting was performed to detect the expression levels of SARM1 and SNPH in the rat retina and optic nerve. Immunofluorescence staining was used to examine their distribution in these tissues. Furthermore, CRISPR/Cas9 technology was used to knock down the expression of SARM1 and SNPH in mouse 661W retinal ganglion cells, respectively. Cells were collected 48 hours after transfection, and Western blotting was performed to detect the expression levels of SARM1 and SNPH. Normally distributed continuous data are presented as mean\u00b1SEM. Comparisons between two groups were performed using the Student's t-test, while comparisons among multiple groups were assessed by the one-way analysis of variance followed by the Tukey's multiple comparisons test. Results: Western blot analysis revealed that in the glaucoma model group, the relative expression level of SARM1 protein in the optic nerve at one week post-modeling (1.22\u00b10.06) was significantly higher than that in the control group (1.03\u00b10.01; P=0.027, q=4.38). In contrast, the expression level of SARM1 in the retina at three days post-modeling (0.79\u00b10.02) was significantly lower than that in the control group (1.04\u00b10.03; P<0.001, q=6.86). Concurrently, the expression level of SNPH at three days post-modeling (0.74\u00b10.01) was lower than that in the control group (1.03\u00b10.04; P=0.040, q=0.58), and its expression at one week post-modeling (1.19\u00b10.10; P=0.002, q=4.36) was significantly higher than that at three days (0.74\u00b10.01). Consistent with the Western blot results, immunofluorescence staining results showed that in the optic nerve of the glaucoma model group, the expression of SARM1 was significantly higher than that in the control group at one week post-modeling, while the expression of SNPH was lower than that in the control group at three days post-modeling. Both proteins partially co-localized with the neuronal marker \u03b23-tubulin. Immunofluorescence staining also revealed co-localization of these two proteins within axons. Additionally, SARM1 co-localized with the mitochondrial marker protein TOM20. Western blot results from 661W cells showed that the knockdown of SARM1 expression (0.54\u00b10.04) significantly reduced SNPH expression (0.54\u00b10.05; P=0.003, q=7.98), whereas the knockdown of SNPH expression (0.39\u00b10.06) did not markedly affect SARM1 levels (0.75\u00b10.05; P=0.010, q=6.39). Conclusion: The elevated expression of SARM1 protein in the axons of the rat glaucoma model can promote retinal ganglion cell axonal pathology by localizing to axonal mitochondria and regulating SNPH expression. \u76ee\u7684\uff1a \u63a2\u8ba8Toll\u6837\u53d7\u4f53\u9002\u914d\u86cb\u767d\u542b\u65e0\u83cc\u03b1\u57fa\u5e8f\u53caToll/\u767d\u4ecb\u7d20\u53d7\u4f53\u57fa\u5e8f\u86cb\u767d1\uff08SARM1\uff09\u8c03\u63a7\u8f74\u7a81\u7ebf\u7c92\u4f53\u951a\u5b9a\u86cb\u767d\uff08SNPH\uff09\u8868\u8fbe\u53c2\u4e0e\u9752\u5149\u773c\u89c6\u795e\u7ecf\u75c5\u53d8\u7684\u673a\u5236\u3002 \u65b9\u6cd5\uff1a \u5b9e\u9a8c\u7814\u7a76\uff0c\u4e8e2024\u5e742\u6708\u81f32025\u5e7410\u6708\u5f00\u5c55\u3002\u7528\u7b80\u5355\u968f\u673a\u6cd5\u5c068~10\u5468Wistar\u96c4\u6027\u5927\u9f20\u5206\u4e3a\u5bf9\u7167\u7ec4\u548c\u9752\u5149\u773c\u6a21\u578b\u7ec4\uff0c\u6bcf\u7ec46\u53ea\u52a8\u7269\uff0c\u5747\u53d6\u53f3\u773c\u7eb3\u5165\u5b9e\u9a8c\u3002\u6a21\u578b\u7ec4\u8fdb\u884c\u524d\u623f\u5fae\u7c92\u78c1\u73e0\u6ce8\u5c04\uff0c\u6784\u5efa\u6162\u6027\u9ad8\u773c\u538b\u9752\u5149\u773c\u6a21\u578b\uff0c\u5728\u9020\u6a21\u540e3 d\u30011\u5468\u548c2\u5468\u53d6\u89c6\u7f51\u819c\u548c\u89c6\u795e\u7ecf\u8fdb\u884c\u5b9e\u9a8c\uff1b\u5bf9\u7167\u7ec4\u5927\u9f20\u524d\u623f\u6ce8\u5c04\u7b49\u4f53\u79ef\u751f\u7406\u76d0\u6c34\u3002\u4f7f\u7528TonoLab\u773c\u538b\u8ba1\u6d4b\u91cf\u5927\u9f20\u773c\u538b\u3002\u91c7\u7528\u89c6\u7f51\u819c\u94fa\u7247Brn3A\u514d\u75ab\u8367\u5149\u67d3\u8272\u68c0\u6d4b\u89c6\u7f51\u819c\u795e\u7ecf\u8282\u7ec6\u80de\uff08RGC\uff09\u4e22\u5931\u60c5\u51b5\u3002\u91c7\u7528Western\u5370\u8ff9\u68c0\u6d4b\u5927\u9f20\u89c6\u7f51\u819c\u548c\u89c6\u795e\u7ecf\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\u60c5\u51b5\u3002\u91c7\u7528\u514d\u75ab\u8367\u5149\u67d3\u8272\u6cd5\u68c0\u6d4b\u5927\u9f20SARM1\u548cSNPH\u5728\u89c6\u7f51\u819c\u548c\u8f74\u7a81\u4e2d\u7684\u8868\u8fbe\u5206\u5e03\u60c5\u51b5\u3002\u5e76\u5229\u7528\u6210\u7c07\u89c4\u5f8b\u95f4\u9694\u77ed\u56de\u6587\u91cd\u590d\u5e8f\u5217\uff08CRISPR\uff09/\u6838\u9178\u5185\u5207\u91769\uff08Cas9\uff09\u6280\u672f\u5206\u522b\u964d\u4f4e\u5c0f\u9f20\u89c6\u7f51\u819c\u795e\u7ecf\u8282\u7ec6\u80de\u7cfb661W\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\uff0c\u8f6c\u67d348 h\u540e\u6536\u96c6\u7ec6\u80de\u3002\u91c7\u7528Western\u5370\u8ff9\u68c0\u6d4b\u7ec6\u80de\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\u60c5\u51b5\u3002\u91c7\u7528\u72ec\u7acb\u6837\u672ct\u68c0\u9a8c\u3001\u5355\u56e0\u7d20\u65b9\u5dee\u5206\u6790\u3001Tukey\u591a\u91cd\u6bd4\u8f83\u8fdb\u884c\u7edf\u8ba1\u5b66\u5206\u6790\u3002 \u7ed3\u679c\uff1a Western\u5370\u8ff9\u7ed3\u679c\u663e\u793a\uff0c\u6a21\u578b\u7ec4\u9020\u6a21\u540e1\u5468\uff0c\u89c6\u795e\u7ecf\u4e2d\u7684SARM1\u86cb\u767d\u7684\u76f8\u5bf9\u8868\u8fbe\u91cf\uff081.22\u00b10.06\uff09\u9ad8\u4e8e\u5bf9\u7167\u7ec4\uff081.03\u00b10.01\uff0cP=0.027\uff0cq=4.38\uff09\u3002\u800c\u89c6\u7f51\u819c\u4e2dSARM1\u86cb\u767d\u8868\u8fbe\u91cf\u5728\u9020\u6a21\u540e3 d\uff080.79\u00b10.02\uff09\u4f4e\u4e8e\u5bf9\u7167\u7ec4\uff081.04\u00b10.03\uff0cP<0.001\uff0cq=6.86\uff09\u3002SNPH\u7684\u8868\u8fbe\u91cf\u5728\u9020\u6a21\u540e3 d\uff080.74\u00b10.01\uff09\u4f4e\u4e8e\u5bf9\u7167\u7ec4\uff081.03\u00b10.04\uff0cP=0.040\uff0cq=0.58\uff09\uff0c\u5e76\u5728\u9020\u6a21\u540e1\u5468\uff081.19\u00b10.10\uff0cP=0.002\uff0cq=4.36\uff09\u8868\u8fbe\u91cf\u9ad8\u4e8e\u9020\u6a21\u540e3 d\uff080.74\u00b10.01\uff09\u3002\u514d\u75ab\u8367\u5149\u67d3\u8272\u7ed3\u679c\u663e\u793a\uff0c\u6a21\u578b\u7ec4RGC\u8f74\u7a81\u4e2dSARM1\u7684\u8868\u8fbe\u5728\u9020\u6a21\u540e1\u5468\u9ad8\u4e8e\u5bf9\u7167\u7ec4\uff0cSNPH\u7684\u8868\u8fbe\u5728\u9020\u6a21\u540e3 d\u4f4e\u4e8e\u5bf9\u7167\u7ec4\u4e0eWestern\u5370\u8ff9\u7ed3\u679c\u4e00\u81f4\u3002\u5e76\u4e14\u90fd\u4e0e\u795e\u7ecf\u5143\u6807\u5fd7\u7269\u5fae\u7ba1\u86cb\u767d\u90e8\u5206\u5171\u5b9a\u4f4d\u3002\u5e76\u4e14\u514d\u75ab\u8367\u5149\u67d3\u8272\u7ed3\u679c\u8fd8\u663e\u793a\u8fd9\u4e24\u79cd\u86cb\u767d\u5728\u89c6\u795e\u7ecf\u4e2d\u5171\u5b9a\u4f4d\u3002SARM1\u4e0e\u7ebf\u7c92\u4f53\u6807\u5fd7\u7269\u86cb\u767dTOM20\u5171\u5b9a\u4f4d\u3002661W\u7ec6\u80de\u4e2dWestern\u5370\u8ff9\u7ed3\u679c\u663e\u793a\uff0cSARM1\u8868\u8fbe\u964d\u4f4e\uff080.54\u00b10.04\uff09\u53ef\u964d\u4f4eSNPH\uff080.54\u00b10.05\uff0cP=0.003\uff0cq=7.98\uff09\u7684\u8868\u8fbe\uff0c\u4f46SNPH\u8868\u8fbe\u964d\u4f4e\uff080.39\u00b10.06\uff09\u5bf9SARM1\u8868\u8fbe\u5f71\u54cd\u8f83\u5c0f\uff080.75\u00b10.05\uff0cP=0.010\uff0cq=6.39\uff09\u3002 \u7ed3\u8bba\uff1a SARM1\u86cb\u767d\u5728\u5927\u9f20\u9752\u5149\u773c\u6a21\u578b\u7ec4\u4e2d\u7684\u89c6\u795e\u7ecf\u4e2d\u8868\u8fbe\u5347\u9ad8\uff0c\u901a\u8fc7\u5b9a\u4f4d\u4e8e\u7ebf\u7c92\u4f53\u8c03\u63a7SNPH\u8868\u8fbe\u53c2\u4e0eRGCs\u89c6\u795e\u7ecf\u75c5\u53d8\u3002."

Stx4 is predominantly localized at the postsynaptic membrane of neurons and in glial cells, where it is essential for synaptic plasticity and the maintenance of neuronal homeostasis. Stx4 facilitates the activity-dependent exocytosis of glutamatergic receptors, thereby governing the balance between Long-Term Potentiation (LTP) and Long-Term Depression (LTD). Emerging evidence suggests that dysregulation of Stx4 is intricately linked to the pathogenesis of neurodegenerative diseases. In Alzheimer's disease, Stx4 is involved in synaptic dysfunction and cognitive impairment through its interactions with amyloid-\u03b2 (A\u03b2) and tau pathologies, affecting receptor recruitment at dendritic spines. In Parkinson's Disease (PD), Stx4 contributes to \u03b1-synuclein proteostasis, dopaminergic signaling, neuroinflammation, and the maintenance of blood-brain barrier integrity. While its presence in cerebrospinal fluid highlights its potential as a candidate biomarker for these diseases, further validation is required to establish clinical utility. This review summarizes current mechanistic insights into Stx4's multifaceted roles in the neurodegenerative disorders and explores the therapeutic prospects of targeting Stx4-mediated pathways due to its translational potential."

This study investigated whether L-serine supplementation could attenuate DN through dose-dependent metabolic and neuroprotective mechanisms in a high-fat diet (HFD) plus streptozotocin (STZ)-induced diabetic rat model. Male Wistar rats (n = 8 per group) were allocated to five groups: normal control (NC), diabetic control (DC), pioglitazone (PIO; 1.5 mg/kg/day), low-dose L-serine (S1; 200 mg/kg/day), and high-dose L-serine (S2; 400 mg/kg/day). After 60 days of oral gavage, behavioural testing, glucose and insulin profiling, HOMA-IR calculation, brain histopathology, nerve growth factor (NGF) immunohistochemistry, and LC-MS/MS-based proteomic analysis of cerebral tissue were performed. Diabetic rats exhibited marked hyperglycaemia (355.33 \u00b1 4.72 mg/dL), hyperinsulinaemia, severe insulin resistance (HOMA-IR 16.8 \u00b1 3.2; a 14-fold increase), impaired thermal nociception, motor dysfunction, and pronounced neuronal degeneration. L-serine supplementation significantly improved metabolic status: S1 reduced HOMA-IR by 77.4% and S2 by 87.5% relative to diabetic controls (p < 0.001). High-dose L-serine produced greater improvements in thermal sensitivity, motor coordination (rotarod latency 26.67 \u00b1 1.52 s vs. 16.1 \u00b1 0.85 s in DC; p < 0.05), and NGF expression (8.6-fold increase vs. DC). Histopathology confirmed attenuation of neuronal injury and gliosis in both treatment groups. Exploratory, group-level proteomic profiling identified dose-specific molecular signatures: S1 was predominantly associated with carbohydrate, lipid, and biosynthetic pathways, whereas S2 was associated with synaptic, neurotransmission-related, and proteostasis pathways. Within the constraints of an exploratory design-group-level pooled proteomics, analysis of cerebral rather than peripheral-nerve tissue, and only two doses-these findings indicate that L-serine attenuates the metabolic and behavioural features of experimental diabetic neuropathy and generates the testable hypothesis of dose-dependent neuro-metabolic remodelling. The proteomic signatures are hypothesis-generating and require orthogonal validation before any mechanistic or translational inference can be drawn."

Methods: In this serial, cross-sectional study, 3 \u00d7 3 mm2 macular OCTA images were obtained from healthy adults and adults with diabetes mellitus (DM) with no diabetic retinopathy (DR) or with mild non-proliferative DR (NPDR). The parameters analyzed included foveal avascular zone (FAZ) area and perimeter, vessel density (VD), vessel length density (VLD), and flow index (FI) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP). The associations between OCTA parameters and age were explored using multivariable linear regression models. Results: For the included 1855 patients (1855 eyes) (49% male; mean age: 55 years), the results were as follows: no diabetes (N = 217), DM no DR (N = 1352), and mild NPDR (N = 286). Increasing age was significantly associated with decreased SCP and DCP VD and VLD in the diabetic and non-diabetic groups. The slope of association between SCP and DCP FI and age in the diabetic patients was significantly different than that in the control patients. Conclusions: The strength of the association between aging and OCTA parameters differed significantly between the controls and those with early retinopathy, pointing to a potentially altered retinal vascular homeostasis secondary to diabetic pathophysiology. This finding offers insight into the early pathological biomarkers of DR and may guide early DR management for patients based on personalized risk scores."

As a result, the treatment of neuropathic pain often requires a multifaceted approach. It has been shown that magnesium ions (Mg2+), which act as physiological antagonists of NMDARs, can augment opioid analgesia in chronic pain. The aim of this study was to assess the influence of Mg2+ on the electrophysiological, analgesic, and brain-derived neurotrophic factor (BDNF)-induced neuromodulation of the morphine profile in diabetic rats. Diabetes in male Wistar rats was induced by a single intramuscular injection of streptozotocin (STZ). The Plantar Test was used to assess the effect of Mg2+ and morphine co-treatment on STZ-induced hyperalgesia, expressed as increased warm sensitivity of the experimental rat hind paw. Ex vivo whole-cell recordings from ventrolateral periaqueductal gray (vlPAG) neurons were conducted to evaluate the frequency of action potentials evoked by incremental depolarizing current steps (current-clamp, 1-s steps). To assess glutamatergic signaling, neurons were voltage-clamped to measure NBQX-sensitive current at -70\u00a0mV and NMDA-evoked currents during depolarization in the presence of NMDA/glycine. Changes in BDNF concentrations in PAG structures were measured using an enzyme-linked immunosorbent assay. The results of our study suggest that although magnesium sulfate shows limited analgesic properties when administered alone, it can significantly enhance opioid efficacy when used as an adjunct. Moreover, the co-administration of morphine with magnesium sulfate resulted in a greater reduction in NMDA-evoked currents in diabetic rats compared to either agent alone. Overall, our findings support the concurrent use of Mg2+ and morphine in the treatment of neuropathic pain as a mechanism-informed adjunct strategy."

Here, we investigate Piezo2 function in the anterior visual pathway of the central nervous system with a focus on oligodendrocyte (OL) biology and myelin integrity. Using single-nucleus RNA sequencing, we identify Piezo2 expression in late differentiated OLs of the murine optic nerve, with minor expression in retinal ganglion cells. OL-specific Piezo2 deficiency results in age-dependent motor impairment and selective disruption of myelin compaction in small-caliber optic nerve axons, a fiber population known to be particularly vulnerable in demyelinating disease. Differential gene expression analysis further indicates that Piezo2 regulates myelin compaction and white matter integrity in mature OLs. Consistent with these findings, OL-encoded PIEZO2 expression is reduced in optic nerve lesion areas from multiple sclerosis patients, highlighting a convergent mechanism of small-caliber fiber vulnerability. Together, these data identify Piezo2 as an age-related regulator of OL function and myelin integrity, with potential relevance for preserving white matter structure in multiple sclerosis."

We conducted an AI-assisted, rule-guided, and manually audited evidence architecture reconstruction of glaucoma-related biomaterial studies published from 2006 to 2025. Records from Web of Science Core Collection, Scopus, and PubMed were integrated, deduplicated, parsed from RIS files, screened, and quality controlled. Retained studies were classified by application scenario, evidence level, and translational features. Core evidence records were assigned to five operational levels, from material preparation and physicochemical characterization to disease-microenvironment intervention, long-term functional integration, and clinical or advanced translational evidence. Theme maturity and the convergence of smart material, additive manufacturing, and tissue-engineering relevance were further assessed. From 1,227 parsed records, 596 were retained, including 547 core evidence studies and 49 review or background records. In the core evidence set, Level 1 to Level 5 evidence included 93, 57, 140, 99, and 158 records, respectively. Level 1-3 evidence accounted for 53.0% of the core evidence set, whereas Level 4-5 evidence accounted for 47.0%, indicating a substantial but unevenly distributed translational component. In situ hydrogels and contact lens-based delivery systems represented the largest application categories, whereas retinal ganglion cell protection, trabecular meshwork modeling, anti-fibrosis after glaucoma surgery, GDD/MIGS-related interfaces, and 3D printing represented smaller but more disease-specific or integration-oriented domains. Glaucoma-related biomaterials are moving beyond passive delivery platforms, but their transition toward smart materials, additive manufacturing, and functional tissue engineering remains uneven. Future studies should emphasize reproducible material design, disease-relevant functional endpoints, outflow-pathway models, neuroprotection, and engineered surgical interfaces."

A rat DR model was established and treated with BBR, and histological analyses, including hematoxylin and eosin staining, Nissl staining, and immunofluorescence, were executed to evaluate tissue changes. Core target genes were identified using the GeneCards database, Venn diagram analysis, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment, protein-protein interaction networks, and molecular docking. Validation of key genes was performed via reverse transcription-quantitative polymerase chain reaction (RT-qPCR), Western blot, and RNA interference. BBR improved retinal morphology, reduced edema, and restored the arrangement of retinal ganglion cells in DR rats. BBR significantly reduced the levels of pyroptosis markers such as IL-1\u03b2 and IL-18, which were elevated in DR. Network pharmacology identified 10 hub genes, with six genes (JUN, STAT3, AKT1, TP53, IL-1B, EGFR) further analyzed. BBR reversed DR-induced upregulation of JUN, STAT3, and AKT1 at both the mRNA and protein levels, as confirmed by RT-qPCR and Western blot. Silencing these genes enhanced cell viability and amplified BBR's protective effects. Altogether, BBR alleviates retinal inflammation and pyroptosis in diabetic retinal ganglion cells by targeting JUN, STAT3, and AKT1, providing insights into its therapeutic potential for DR."

Recent literature supports a shift toward neurovascular unit (NVU) protection, where pharmacological agents like SPG302 target synaptic and mitochondrial integrity. Evidence suggests that preserving retinal ganglion cells (RGCs) and synaptic markers through targeting metabolic pathways (such as Nrf2, AMPK, and nuclear receptors) may prevent progressive visual loss in diabetes and glaucoma.\n\n### [INTRODUCTION & JUSTIFICATION]\nDiabetic retinopathy is no longer classified solely as a microvascular pathology; it is increasingly recognized as a neurovascular degenerative disease involving coordinated injury to the retinal neurovascular unit. Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function, decreased inner retina synaptic markers, and increased reactive gliosis and cell death. The molecular mechanisms driving this include mitochondrial dysfunction, where high glucose flux promotes mitochondrial reactive oxygen species overproduction and oxidative stress. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma, another leading cause of blindness associated with early synapse loss in the retina. Db/db mice demonstrated significant loss of GC ERG signal and GC cell number, decreased PSD95 and synaptophysin expression indicative of synapse loss, as well as increased reactive gliosis and expression of cell death markers such as pBAD and BAX. SPG302 treatment effectively preserved retinal integrity by reversing these changes. Such findings underscore the necessity of shifting clinical thinking from late vascular rescue toward mechanism-based neurovascular protection.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Neurodegeneration in glaucoma often involves transsynaptic degeneration extending into secondary and higher-order visual brain regions.\n*   In diabetic retinopathy, mitochondrial fission acts as a pathological initiator, suppressing the Hippo pathway and promoting M\u00fcller cell activation.\n*   GPR75 knockdown provides a therapeutic strategy for alleviating mitochondrial dysfunction in retinal ganglion cells via the AMPK pathway.\n*   Sigma1 receptor (Sig1R) activation provides durable neuroprotection by coordinating redox, mitochondrial, and cell-survival pathways.\n*   Synaptic proteins such as Syntaxin-4 regulate membrane trafficking essential for maintaining neuronal homeostasis in the retina.\n*   Short-chain fatty acids like propionic acid show promise in reducing serum neurofilament light chain levels, indicating attenuation of neuroaxonal injury.\n*   The interaction between microglia and M\u00fcller cells is modulated by fibroblast growth factor 1 (FGF1), which is downregulated in glaucomatous retinas.\n*   Intranasal delivery of neuroprotective agents offers a potential non-invasive strategy for posterior segment ocular disease, bypassing the blood-retinal barrier.\n*   Panoptosis, an integrated programmed cell death modality, serves as a dynamic framework for interpreting inflammatory neurovascular degeneration in diabetic retinopathy.\n*   Targeting the liver-brain axis via Licochalcone A or other agents may provide systemic protection against metabolic neurodegeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

We used three nationwide health examination surveys conducted in 2000, 2011 and 2017, with a total of 18\u2009966 participants representing the Finnish population aged 18\u2009years and older. All surveys were linked to national health registers covering diagnoses related to diabetes and DR between 2000 and 2017. All surveys included a health examination, in which distance and near VAs were measured. All data were analysed at the individual level. The prevalence of type 2 diabetes increased from 2.6% to 9.6% between 2000 and 2017, while its annual incidence increased from 0.5% to 0.7%. The annual incidence of DR among type 2 diabetes patients decreased from 1.4% to 0.3% between 2000 and 2017. Both distance and near VA were the best among individuals without diabetes, significantly worse among type 2 diabetes patients without DR, and the worst among type 2 diabetes patients with DR. Both distance and near VAs significantly improved between 2000 and 2017 in these study groups. The prevalence of type 2 diabetes has increased during the 2000s, which can be explained by the improved screening and unfavourable changes in lifestyle. However, the incidence of DR has decreased among type 2 diabetes patients, indicating the successful development and effectiveness of screening and therapies for both diabetes and DR.\n\nID: 42456876\nTitle: SPG302 Mitigates Diabetic Retinal Neuropathy and Inner Retinal Damage in a Genetic Mouse Model of Diabetes.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss stemming from vascular and neurodegenerative sequelae of impaired glucose metabolism. Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function, decreased inner retina synaptic markers, and increased reactive gliosis and cell death. Loss of glutamatergic synapses in the retina precedes, and may contribute to, overt neuron loss in DR, thus offering a potential new point for therapeutic intervention. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma, another leading cause of blindness associated with early synapse loss in the retina. To evaluate potential protective effects of SPG302 in DR, db/db mice (a diabetic mouse model with an inactivation mutation in the leptin receptor) were treated with intraperitoneal SPG302 or vehicle for 8 weeks (16-24 weeks of age). Db/+ mice served as an additional control. Db/db mice demonstrated weight gain, hyperglycemia, insulin intolerance, and glucose intolerance, while db/+ mice did not. SPG302 treatment did not change these metabolic parameters. Following treatment, GC function was assessed using electroretinography (ERG). Mice were then euthanized for quantification of retinal GCs, synaptic markers, glial markers, and markers of cell death using immunofluorescence staining and Western blot methods. Db/db mice demonstrated significant loss of GC ERG signal and GC cell number, decreased PSD95 and synaptophysin expression indicative of synapse loss, as well as increased reactive gliosis and expression of cell death markers such as pBAD and BAX. SPG302 treatment effectively preserved retinal integrity by reversing these changes. Thus, SPG302 has therapeutic potential for protecting the inner retina and mitigating DRN in diabetes.\n\nID: 42456827\nTitle: GPR75 knockdown alleviates mitochondrial dysfunction in retinal ganglion cells via AMPK pathway in diabetic mice.\nAbstract: Mitochondrial dysfunction plays a crucial role in retinal ganglion cells (RGCs) injury, the early pathogenesis of diabetic retinopathy (DR). G protein-coupled receptor 75 (GPR75), an orphan receptor, is a novel regulator of metabolic diseases. However, the role and mechanisms of GPR75 underlying diabetic RGCs mitochondrial dysfunction have not been reported. To investigate the function of GPR75, we knockdown the receptor in streptozotocin (STZ) mice and high glucose (HG)-treated primary RGCs. Our investigations revealed an upregulation of GPR75 in DR. Furthermore, we demonstrated that GPR75 knockdown could mitigate the progression of DR, with its protective effects associated with the inhibition of mitochondrial dysfunction in RGCs. Adenosine-5'-monophosphate (AMP)-activated protein kinase (AMPK), a regulator of mitochondrial function and a cellular energy sensor, was identified as a novel target of GPR75. Immunofluorescence and co-immunoprecipitation (CO-IP) analyses confirmed the co-localization and interaction between GPR75 and AMPK in RGCs. Mechanistically, the upregulation of GPR75 inhibits AMPK-mediated mitochondrial homeostasis, resulting in impaired mitochondrial dynamics, disrupted energy metabolism, and elevated reactive oxygen species (ROS), which ultimately trigger pyroptosis and apoptosis in RGCs. Notably, the AMPK-activator AICAR mitigates GPR75-induced mitochondrial dysfunction, pyroptosis, and apoptosis. In summary, our findings suggest that the targeted inhibition of GPR75 may represent a promising therapeutic strategy for DR.\n\nID: 42453979\nTitle: Efficacy of Avastin in Improving Visual Acuity and Reducing Retinal Swelling in Patients with Diabetic Retinopathy at a Hospital in Gauteng (SA).\nAbstract: Globally, diabetic retinopathy (DR) has been identified as the cause of blindness among adults with both Type 1 diabetes (T1DM) and Type 2 diabetes (T2DM). The study aimed to investigate the efficacy of Avastin in improving visual acuity (VA) and reducing central foveal (CFT) and parafoveal thicknesses (PFT) in participants with DR. A cross-sectional observational study was conducted at a tertiary hospital in the Gauteng Province (South Africa). A total of 55 participants were included in the study, with VA's that were less than 0.5 LogMAR units and CFT's greater than 300 microns (\u00b5m). Measurements of VA's, CFT (\u00b5m), and PFT (\u00b5m) were conducted at baseline, after three and six months of receiving Avastin treatment. Numerical data were collected and analysed using IBM SPSS Version 28, and non-parametric tests were used to compare the means of the variables. The mean VA improved from 1.00\u00b10.71 LogMAR at baseline to 0.66\u00b10.51 and 0.57\u00b10.48 LogMAR at 3 and 6 months, respectively (p <0.001). The mean CFT improved from 441.22\u00b1142.35\u00a0\u00b5m at baseline to 355.58\u00b1129.38\u00a0\u00b5m and 308.40\u00b1137.60\u00a0\u00b5m at 3 and 6 months, respectively (p <0.001). The superior parafoveal thickness (SPFT) showed the highest decrease from a mean baseline of 379.04\u00a0\u00b5m to a mean baseline of 317.36\u00a0\u00b5m at 3 months. At 6 months, the decrease in the NPFT was statistically significant (p <0.025) in improving VA. Early administration of Avastin treatment in diabetic patients is effective in reducing the mean CFT, NPFT, and improving the mean VA.\n\nID: 42450538\nTitle: The Interaction Between Insulin Resistance and Neuroinflammation in the Brain and Its Impact on Diabetic Encephalopathy.\nAbstract: Diabetic encephalopathy (DE) is a severe complication of diabetes mellitus affecting the central nervous system (CNS), characterized by cognitive dysfunction. This review systematically explores how the interplay between brain insulin resistance (BIR) and neuroinflammation contributes to the pathogenesis of DE. BIR refers to the diminished responsiveness of the CNS to insulin signaling, resulting in the suppression of the PI3K/Akt and MAPK pathways, impaired glucose metabolism, and dysfunction across multiple neural cell types-including neurons, astrocytes, microglia, brain endothelial cells, and oligodendrocytes. These disturbances manifest as impaired energy metabolism, compromised synaptic plasticity, disruption of the blood-brain barrier, and reduced myelination. Importantly, BIR and neuroinflammation form a vicious cycle within these cells, mutually exacerbating each other and jointly driving the pathological progression of DE. Finally, we have compiled a list of currently available drugs that can improve BIR and suppress neuroinflammation, along with the latest progress in clinical trials, to provide new insights for the future of precision treatment for DE.\n\nID: 42436854\nTitle: AAV-norrin gene therapy rescues retinal defects in mice with Norrie disease and oxygen-induced retinopathy.\nAbstract: Norrin, secreted by retinal M\u00fcller cells, activates canonical Wnt signaling via Frizzled-4 and co-receptors. Loss-of-function mutations abolish intraretinal capillary formation in mice. In humans, mutations in NDP, which encodes norrin, cause Norrie disease, characterized by retinal hypovascularization and congenital blindness, and X-linked familial exudative vitreoretinopathy (FEVR), resembling retinopathy of prematurity (ROP). We evaluated adeno-associated viral (AAV) vectors expressing norrin as gene therapy for Norrie disease, FEVR, and ROP. AAV2-7m8 and AAV-ShH10 were tested in juvenile wild-type and norrin-deficient (Ndp KO) mice via intravitreal injection at postnatal day 7, with some mice subjected to oxygen-induced retinopathy (OIR). AAV2-7m8 transduced M\u00fcller glia, while AAV-ShH10 targeted retinal ganglion cells. Both vectors fully restored intraretinal capillary growth in Ndp KO mice, normalizing vessel density and plexus organization, preserving the blood-retinal barrier, and rescuing visual function. In OIR, scAAV2-7m8-huNorrin reduced vaso-obliteration and neovascular tuft formation, increasing deep plexus coverage, and suppressed Vegfa164 and Ang-2 upregulation. The findings demonstrate that AAV-mediated norrin delivery efficiently targets retinal glia and neurons, restores vascular structure and function, stabilizes the blood-retinal barrier, and mitigates OIR-induced pathological angiogenesis, supporting its potential as a therapeutic strategy for Norrie-related retinopathies and ROP.\n\nID: 42435779\nTitle: Targeting the liver-brain axis: Licochalcone A as a therapeutic agent against HFD-induced neurodegeneration.\nAbstract: The understanding of neurodegenerative diseases is evolving toward a systemic view, highlighting the connection between liver dysfunction and brain impairment, where metabolism and inflammation play central roles. Licochalcone A (LCA), has demonstrated antidiabetic and anti-inflammatory effects. This study aimed to evaluate its neuroprotective effects under metabolic syndrome conditions. For this purpose, male C57BL/6J mice were fed either with control (CT) or high-fat diet (HFD) from weaning. At eight months, animals received intraperitoneal LCA (15\u202fmg/kg/day) or saline three times per week for four weeks. The resulting groups were CT Saline, HFD Saline, and HFD LCA. Cognitive and metabolic alterations were assessed through behavioral tests and glucose/insulin tolerance assays. Peripheral and/or central markers of metabolism, amyloid burden, inflammation, and synapsis were analyzed using histological staining, immunohistochemistry, Golgi staining, Western blot, ELISA, and RT-PCR. The results demonstrated that LCA administration improved metabolic outcomes by reducing body and liver weight, enhancing glucose tolerance, and improving liver histology. These effects were associated with modulation of insulin signaling pathways, including PTP1B inhibition and AKT activation in the liver and the hippocampus. LCA also reduced HFD-induced A\u03b2 accumulation, which was accompanied by increased LRP1 expression, and attenuated the expression of inflammatory related markers, such as TLR4 and glial activation. Moreover, these improvements were associated with increased levels of synaptic proteins (BDNF, PSD95, DBN1), and synaptic plasticity markers (P-CREB and P-LIMK1), along with preservation of dendritic spine density and improved memory performance. In conclusion, these findings support LCA as a promising candidate for treating HFD-induced neurodegenerative conditions, acting through modulation of metabolic and inflammatory pathways across the liver-brain axis.\n\nID: 42433616\nTitle: Corneal Anterior and Posterior Changes in a Patient With Keratitis Associated With Mycobacterium chelonae: A Case Report.\nAbstract: This report describes a patient with anterior and posterior corneal topographic changes who developed refractory keratitis due to Mycobacterium chelonae, associated with soft contact lens use. A 42-year-old man presented with blurred vision and pain in his right eye. He used disposable soft contact lenses for 2 weeks with appropriate care. He had open-angle glaucoma, atopic dermatitis, and diabetes mellitus. At the initial presentation, a corneal epithelial defect, cell infiltration, strong hyperemia, hypopyon, and inflammation in the anterior chamber were observed. Anterior segment optical coherence tomography disclosed corneal edema and cloudiness, and the central corneal thickness had increased to 988\u2009\u03bcm. The best-corrected visual acuity was counting fingers at 10\u2009cm. The patient did not respond to the initial treatment with ofloxacin and steroids. The culture of the scraped sample from the contact lens case grew M. chelonae, and topical tobramycin was administered, which was effective based on antimicrobial susceptibility. It took 4 months to treat the keratitis, and the best-corrected visual acuity improved to 0.5, although anterior and posterior corneal irregularities remained. Nontuberculous M. chelonae should be considered in patients with treatment-resistant keratitis, especially in contact lens users. Topographic changes are important for evaluating corneal edema and irregular astigmatism, which impair visual function after keratitis.\n\nID: 42429483\nTitle: YAP Regulates the Nrf2 Signaling Axis to Attenuate Oxidative Stress and Neuroinflammation in Retinal Ganglion Cell Degeneration.\nAbstract: Oxidative stress is a key driver of retinal ganglion cell (RGC) degeneration after optic nerve injury. Yes-associated protein (YAP), a Hippo pathway effector, is known to reprogram stress responses, yet its role in regulating oxidative stress during RGC degeneration is unclear. This study investigated the role of YAP in RGC injury using an in vivo optic nerve crush (ONC) model and an in vitro oxidative-stress model with primary RGCs. YAP expression was modulated pharmacologically and genetically. We assessed its effects on nuclear factor erythroid 2-related factor 2 (Nrf2) signaling-related outcomes; on oxidative stress markers, including superoxide dismutase-1/2 (SOD-1/2), NAD(P)H:quinone oxidoreductase 1 (Nqo-1), and reactive oxygen species (ROS); and on neuroinflammation (microglial and astrocytic activation) via quantitative reverse-transcription PCR and immunofluorescence. YAP activation demonstrated robust neuroprotection in both the in vivo ONC model and in vitro oxidative-stress paradigms, significantly enhancing RGC survival, whereas YAP suppression exacerbated RGC degeneration. Mechanistically, YAP activation was associated with elevated Nrf2 signaling activity, as indicated by upregulation of antioxidant effectors (Nqo-1, SOD-2) and reduced intracellular ROS. YAP activation attenuated neuroinflammation, characterized by decreased microglial reactivity and astrocytic activation, whereas inhibition of YAP reversed these effects. This study identified YAP as a neuroprotective regulator in both in vivo ONC and primary RGC models. YAP activation attenuated oxidative stress and neuroinflammation, which correlated with the activity of Nrf2-mediated antioxidant pathways, highlighting the potential relevance of YAP and Nrf2 interaction for therapeutic targeting in RGC injury.\n\nID: 42427758\nTitle: Exosomal Profiling Reveals Mechanisms of Hibernation-Associated Neuroprotection.\nAbstract: Glaucoma is a group of eye diseases that affects 4 million people in the US and is one of the leading causes of vision loss due to damage to the eye's optic nerve (ON) which is composed of axons from retinal ganglion cells (RGCs) that transmit visual information to the brain. Injury to the ON often triggers RGC death and subsequent loss of visual function. Despite its increasing prevalence worldwide, effective therapies for glaucoma remain elusive. Notably, the thirteen-lined ground squirrel (TLGS) exhibits intrinsic neuroprotection during hibernation; however, reproducing this protective state pharmacologically has proven challenging. To elucidate the metabolic mechanisms underlying this resilience, we conducted untargeted metabolomic analyses on TLGS retinas at 6 hours, 3 days, and 7 days following ON crush. Retinas from awake and hibernating animals were compared to identify temporal and state-dependent metabolic signatures. Distinct metabolomic profiles were observed in hibernating animals relative to their awake counterparts. Pathway analyses revealed coordinated regulation of amino acid, lipid, and purine metabolism that likely contributes to hibernation-induced resilience. Furthermore, our findings indicate that hibernating TLGS retinas increase exosome biogenesis, prompting in vitro validation using TLGS-derived exosomes, which demonstrated robust neuroprotective and anti-inflammatory effects. Proteomic and transcriptomic characterization of exosomal cargo identified conserved miRNAs, mRNAs, and proteins implicated in redox balance, cytoskeletal stabilization, and stress-response regulation. Collectively, these data support the hypothesis that metabolic reprogramming and exosome-mediated intercellular signaling underlie hibernation-associated neuroprotection. Modulating these pathways may provide a blueprint for novel therapeutic strategies to mitigate neurodegeneration and promote recovery following optic nerve injury.\n\nID: 42427061\nTitle: Aflibercept with and without laser therapy in diabetic macular edema: a systematic review and meta-analysis.\nAbstract: Diabetic macular edema (DME) causes visual impairment in diabetic patients. Aflibercept is a standard treatment of DME; however, the benefit of combining it with laser therapy remains uncertain. A systematic review of randomized controlled trials (RCTs) comparing aflibercept alone with a combination of aflibercept plus laser therapy for management of DME was conducted. PubMed, Cochrane Library, and Embase were searched according to PRISMA guidelines. Primary outcomes were best corrected visual acuity (BCVA) and central macular thickness (CMT), while secondary outcome was treatment burden. Six RCTs involving 275 patients were included. At 12\u2009months, combination therapy yielded a modest improvement in BCVA (mean difference [MD]\u2009=\u20090.18; 95% CI: -0.17 to 0.52; p\u2009=\u20090.32) and a minor reduction in CMT (MD\u2009=\u20090.13\u2009\u03bcm; 95% CI: -0.13 to 0.39; p\u2009=\u20090.32). The number of aflibercept injections was slightly lower in the combination group (MD = -0.53 injections; 95% CI: -1.23 to 0.17; p = 0.14). The adjunctive use of laser therapy with aflibercept in DME does not provide statistically significant improvement in visual or anatomical outcomes over aflibercept alone. Diabetic macular edema (DME) is a common eye disease in diabetic patients, causing blurred vision and even vision loss. Aflibercept is a standard drug for DME treatment. Sometimes, laser treatment is also used along with aflibercept. This study explored whether adding laser therapy to aflibercept provides extra benefit in DME treatment. Systematic review of literature and meta-analysis showed that patients who received both aflibercept and laser therapy had slightly better vision and a small reduction in retinal swelling compared with those who received aflibercept alone. Moreover, patients receiving the combination treatment also required slightly fewer injections. In summary, adding laser therapy to aflibercept does not appear to provide clear additional benefit in improving vision or reducing retinal swelling. There may be a small reduction in the number of injections needed, but more research is required to confirm this finding.\n\nID: 42426919\nTitle: Effectiveness and safety of intravitreal faricimab for macular oedema secondary to retinal vein occlusion: a systematic review and meta-analysis.\nAbstract: Faricimab is a bispecific monoclonal antibody targeting both vascular endothelial growth factor A and angiopoietin-2, approved for macular oedema secondary to retinal vein occlusion in 2023. The phase III BALATON and COMINO trials demonstrated non-inferiority to aflibercept at week 24, and several real-world cohorts have subsequently emerged. The aim of this systematic review and meta-analysis was to estimate the pooled effect of faricimab on visual acuity, treatment burden, anatomical outcomes, and safety in this indication. PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials were systematically searched from inception to 1 May 2026 for studies reporting outcomes following intravitreal faricimab. Risk of bias was assessed in duplicate using the Cochrane Risk of Bias 2 tool for the randomised evidence and the Risk Of Bias In Non-randomised Studies of Interventions tool for the observational evidence, with single-arm cohorts evaluated as pre-post comparisons. The primary visual acuity outcome was pooled using random-effects meta-analysis with Hartung-Knapp-Sidik-Jonkman adjustment, stratified by treatment status, while outcomes precluded from pooling by methodological heterogeneity were synthesised narratively. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation framework. Ten studies comprising 1,620 eyes met eligibility criteria, including the BALATON and COMINO randomised controlled trials and nine non-randomised cohorts. The pooled mean change in best-corrected visual acuity at approximately 6 months was +\u200916.89 Early Treatment Diabetic Retinopathy Study letters (95% confidence interval 16.05 to 17.72) in treatment-na\u00efve eyes and +\u20098.73 letters (95% confidence interval 4.75 to 12.71) in refractory switch cohorts, with negligible between-study heterogeneity in both analyses. Narrative synthesis was consistent with treatment interval extension following initiation of or switch to faricimab, statistically significant reductions in central retinal thickness across studies, and a short-term safety profile without identified retinal vasculitis events. The synthesis is consistent with intravitreal faricimab use being associated with visual and anatomical improvement in macular oedema secondary to retinal vein occlusion, with the treatment-na\u00efve pooled estimate primarily reflecting registration trial data and the switch cohort estimate characterising refractory phenotypes.\n\nID: 42425282\nTitle: Microglia suppress M\u00fcller cell FGF1 and contribute to retinal ganglion cell degeneration in glaucoma.\nAbstract: Glaucoma is a progressive neurodegenerative disease characterized by retinal ganglion cell (RGC) loss, in which glial activation and neuroinflammation contribute importantly to disease progression. However, the mechanisms by which microglia-M\u00fcller cell interactions influence retinal neuroinflammation and neurotrophic support during glaucoma remain unclear. Here, we aimed to identify glia-associated regulatory factors involved in microglia-M\u00fcller cell communication during glaucoma and to determine their contribution to retinal neurodegeneration. A chronic ocular hypertension (COH) mouse model and a conditioned medium (CM)-based inflammatory system were used to investigate microglia-M\u00fcller cell interactions and the role of fibroblast growth factor 1 (FGF1) in retinal neuroinflammation. Sustained intraocular pressure (IOP) elevation induced glial activation and progressive RGC degeneration in COH retinas. Transcriptomic profiling of M\u00fcller cells exposed to microglia-CM identified FGF1 as a significantly downregulated candidate neurotrophic factor, accompanied by enrichment of immune and inflammatory pathways. Functionally, M\u00fcller cell FGF1 deficiency exacerbated, whereas exogenous FGF1 attenuated, inflammation-induced RGC apoptosis in vitro. In vivo, intravitreal rFGF1 reduced RGC apoptosis, preserved RGC survival, and maintained retinal structure without affecting IOP. Consistently, reduced FGF1 expression was observed in M\u00fcller cell-enriched regions of human glaucomatous retinas. Together, these findings suggest that microglia-driven inflammation suppresses M\u00fcller cell FGF1 expression, thereby impairing neurotrophic support and increasing retinal vulnerability during COH. Restoration of FGF1 signaling confers neuroprotection independently of IOP reduction and may represent a promising glia-targeted therapeutic strategy for glaucoma.\n\nID: 42422405\nTitle: Neuroprotective Effects of Ethiopian Coffee Beans against Hyperglycemia-induced Brain Injury in Rats.\nAbstract: At least 50% of people with diabetes suffer from one or more complications if their conditions are not adequately managed over time. Diabetic neuropathy is one of the prevalent complications of diabetes, which also includes diabetic nephropathy, retinopathy, cardiomyopathy, and diabetic foot diseases. The present study evaluated the protective effects of Ethiopian coffee beans (Coffea arabica) against glucose-induced brain tissue injury using in\u00a0vitro, ex\u00a0vivo, and in silico experimental models. Oxidative injury was induced by incubating brain tissue collected from normal male Sprague-Dawley rats in glucose solution and treated with the different concentrations of Ethiopian coffee bean extracts (hot and cold aqueous) for 2\u2009h at 37\u00b0C in a 95% O2 and 5% CO2 incubator. Induction of glucose-mediated (0.0111\u2009M glucose) oxidative injury led to significant depletion of reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), and total glycogen levels, while elevating malonaldehyde (MDA), nitric oxide (NO), glycogen phosphorylase, fructose-1,6-bisphosphatase, ATPase, and acetylcholinesterase (AChE) activity levels. Treatment with different concentrations of the aqueous extracts of coffee beans significantly restored the levels and activities of the biomarkers mentioned above. LC-MS analysis indicates the presence of chlorogenic acid (CGA), caffeic acid, quinic acid, caffeine, Cafestol, Kahweol, ferulic acid, and catechol in the coffee extracts. In silico analysis revealed a strong molecular interaction between CGA and the CAT, SOD, and AChE enzymes. The data from this study suggest that bioactive compounds from Coffea arabica have a potential neuroprotective effect against glucose-mediated oxidative neurodegeneration in rat brain tissue.\n\nID: 42416940\nTitle: Early Postoperative Outcomes of Phacoemulsification With Concurrent Silicone Oil Removal in a Tertiary Eye Care Hospital of Bangladesh.\nAbstract: \u00a0Silicone oil (SO) tamponade is essential in managing complex vitreoretinal conditions but is associated with complications such as cataract formation and secondary glaucoma. Combining SO removal (SOR) with cataract surgery in a single procedure may improve patient convenience and outcomes. This study aims to evaluate the early postoperative outcomes of phacoemulsification with concurrent SOR in a tertiary eye care hospital of Bangladesh. \u00a0This prospective longitudinal study was conducted at Ispahani Islamia Eye Institute and Hospital, Dhaka, Bangladesh, from January 1, 2023, to June 30, 2023. Patients who had previous surgery due to retinal detachment (RD) or advanced diabetic eye disease with SO used as an internal tamponade with postoperative cataract formation and an attached retina, confirmed by indirect ophthalmoscopic examination or B scan, depending on media clarity, were included in the study. Phacoemulsification with intraocular lens implantation was performed, followed by SOR using the 23-gauge\u00a0pars plana method. Postoperative follow-ups were conducted at day 1, day 7, and at least after 1 month to record visual acuity, complications, and retinal status. \u00a0Out of 42 patients, a majority of patients (13, 31.0%) belonged to the age group of 50-59 years with a mean age of 44.38 \u00b1 14.4 years. The male-to-female ratio was 4:3. The primary pathology was tractional RD secondary to diabetic retinopathy in 24 eyes and rhegmatogenous RD in 18 eyes. There was an improvement in at least one-third of patients' visual acuity postoperatively as recorded by the Snellen chart. Retina was attached in 41 (97.6%) patients, while 1 (2.4%) patient had a redetached retina at the last follow-up. \u00a0Phacoemulsification with concurrent SOR is a useful method that is associated with acceptable visual and anatomical outcomes, and it eliminates the burden for another surgery for cataract extraction.\n\nID: 42401762\nTitle: Aflibercept 24-Month Outcomes in Diabetic Macular Edema With and Without Prior Macular Laser Therapy: Data from the Fight Retinal Blindness! Registry.\nAbstract: We evaluated 24-month real-world outcomes of intravitreal aflibercept 2\u00a0mg for diabetic macular edema (DME) in treatment-naive eyes and eyes previously treated with macular thermal laser photocoagulation. This retrospective observational cohort study analyzed data from a prospectively designed treatment outcomes registry. We described outcomes separately in treatment-naive eyes and eyes previously treated with macular thermal laser photocoagulation, all of which received intravitreal aflibercept 2\u00a0mg for DME in routine clinical practice. Given the small number of eyes with prior macular laser, findings in this subgroup were considered descriptive and exploratory. The main functional outcome was change in visual acuity (VA) from baseline at 6, 12, and 24\u00a0months. The main anatomical outcome was change in central subfield thickness (CST) from baseline at the same time points. Secondary outcomes were injection and visit burden, changes in center-involving clinically significant macular edema activity, time to additional macular laser treatment, and ocular adverse events. The cohort included 122 eyes from 78 patients: 110 treatment-naive eyes and 12 eyes with prior macular laser. In treatment-naive eyes, mean VA improved from baseline by 5.5, 5.0, and 5.5 letters at 6, 12, and 24\u00a0months, respectively. Mean CST decreased by 105.9\u00a0\u00b5m, 90.4\u00a0\u00b5m, and 97.1\u00a0\u00b5m, respectively. In eyes with prior macular laser, changes in VA were not statistically significant at any follow-up point. CST decreased significantly at 6\u00a0months (-36.5\u00a0\u00b5m) and 12\u00a0months (-37.5\u00a0\u00b5m), but not at 24\u00a0months (-26.1\u00a0\u00b5m). By month 24, the median number of injections was 12 in treatment-naive eyes and 11 in eyes with prior macular laser. Additional macular laser was rarely needed, and ocular adverse events were rare. In routine clinical care, intravitreal aflibercept 2\u00a0mg for DME was associated with sustained anatomical improvement and modest, largely stable visual gains over 24\u00a0months, particularly in treatment-naive eyes. These findings support favorable real-world outcomes with aflibercept, although subgroup findings in eyes with prior macular laser should be interpreted cautiously.\n\nID: 42401758\nTitle: Mitochondrial insufficiencies and neuroprotection in glaucoma.\nAbstract: Antihypertensive management has long been the mainstay of treatment for glaucoma. Despite contemporary treatments, many patients still experience disease progression, with some ultimately losing vision. The purpose of this review is to demonstrate how derangements in mitochondrial biology underpin the pathophysiology of glaucoma, and to explore emerging therapeutic options. Literature searches were performed using multiple databases, aiming to identify recent developments in the scientific knowledge surrounding mitochondrial biology and glaucoma. Key words used in the primary literature search included combinations of \"glaucoma\", \"mitochondria\", \"oxidative stress\", \"metabolism\", \"inflammation\", \"transport\" and \"genetics\". Additional database searches were performed to further explore specific details identified in the primary search. Recent research points to mitochondrial insufficiencies as a primary culprit in the pathophysiology of glaucoma. Dysfunction of mitochondria occurs in a multitude of ways, and is an integral component of neuroinflammation, metabolic compromise, and disruption of axonal transport. This in part results from accumulated genetic factors, leading to generation of superoxides that damage retinal ganglion cells resulting in neurodegeneration of the optic nerve. Defects in mitochondrial biology among a range of ocular cell types contribute to the progression of glaucoma. With this understanding, emerging treatments targeting mitochondria, including gene therapies, tunneling nanotubules, and pharmacotherapeutics which enhance mitochondrial function and reduce oxidative stress, are likely the future of glaucoma management. By targeting mitochondrial insufficiencies as a root cause of glaucoma in addition to managing intraocular pressure, this new approach offers hope for preventing vision loss and potentially curing glaucoma.\n\nID: 42399554\nTitle: Intraoperative Modified Peripheral Panretinal Photocoagulation in Proliferative Diabetic Retinopathy.\nAbstract: This study aimed to compare the outcomes of intraoperative conventional panretinal photocoagulation (CPRP) with the modified peripheral panretinal photocoagulation (PPRP) technique in pars plana vitrectomy (PPV) in patients with proliferative diabetic retinopathy (PDR). Sixty-three eyes of 56 patients with PDR were retrospectively studied. Patients with very severe proliferation were excluded in this study. Twenty-six patients (30 eyes) received CPRP and 30 patients (33 eyes) received modified PPRP in PPV. Preoperative and postoperative ophthalmologic examinations were performed. Best corrected visual acuity (BCVA) was performed at baseline and 3\u00a0months after surgery. Central macular thickness (CMT) was measured at 1\u00a0week and 3\u00a0months after surgery. Postoperative inflammation was examined at 1\u00a0day and 3\u00a0months after surgery. Other postoperative complications were also analyzed at 3\u00a0months after surgery. Of all the included eyes, 24 eyes (38.1%) were diagnosed with neovascularization elsewhere (NVE) and/or neovascularization of the disc (NVD) and 39 eyes (61.9%) were diagnosed with tractional retinal detachment (TRD) preoperatively. The number of laser spots in the CPRP group ranged from 858 to 2245, with an average of 1232 (1048,1369) spots. The number of laser spots in the PPRP group ranged from 394 to 992, with an average of 673 (579, 798) spots. The mean logMAR BCVA before surgery was 1.71\u2009\u00b1\u20090.57 in the CPRP group and 1.57\u2009\u00b1\u20090.64 in the modified PPRP group, with no statistical difference between the two groups (P\u2009=\u20090.476). The mean logMAR BCVA was 1.15\u2009\u00b1\u20090.74 in the CPRP group and 0.77\u2009\u00b1\u20090.54 in the PPRP group at 3\u00a0months after surgery, showing that the PPRP group had more visual acuity improvement than the CPRP group (P\u2009=\u20090.037). There was a significant correlation between BCVA and the number of laser spots (P\u2009=\u20090.006). The difference of CMT between the two groups was statistically significant at 1\u00a0week after surgery (P\u2009=\u20090.02), but not at 3\u00a0months after surgery (P\u2009=\u20090.587). The postoperative inflammation in the CPRP group was significantly more severe than that in the PPRP group at the first day after surgery (P\u2009=\u20090.002). The postoperative inflammation in both groups was significantly reduced 3\u00a0months after surgery, with no statistical difference (P\u2009=\u20090.593). There was a significant correlation between the degree of inflammation and the number of laser spots at the first day after surgery (P\u2009=\u20090.016). There was no significant difference in the incidence of other complications between the two groups. The modified PPRP technique was used during PPV in patients with PDR in this study, resulting in better BCVA, decreased CMT, and reduced early postoperative inflammation without increasing the incidence of adverse events in PDR.\n\nID: 42398881\nTitle: Mitochondrial Dysfunction and Diabetic Retinopathy: Research Progress from Pathogenic Mechanisms to Therapeutic Targets.\nAbstract: Diabetic retinopathy (DR) is one of the most common microvascular complications of diabetes mellitus (DM) and remains a major cause of visual impairment and blindness in adults. Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment.\n\nID: 42396532\nTitle: Validation of Deep Capillary Plexus OCTA Metrics as Predictors of Diabetic Retinopathy Complications: A One-Year Longitudinal Study.\nAbstract: Diabetic retinopathy (DR) can lead to vision-threatening complications, and tools that capture microvascular damage beyond standard clinical grading of disease severity may improve risk prediction. Optical coherence tomography angiography (OCTA) quantifies retinal perfusion, but its prognostic value in referable DR is not fully established. We aimed to validate baseline deep capillary plexus (DCP) OCTA metrics for predicting one-year complications in eyes with referable DR. In this prospective longitudinal study in 137 eyes of 96 participants, we assessed baseline predictors of DR complications, defined as best-corrected visual acuity (BCVA) loss (\u2265 10 letters on the ETDRS chart), center-involving diabetic macular edema, anti-VEGF injections, pan-retinal photocoagulation, or vitreous hemorrhage. Baseline variables included BCVA, low-luminance visual acuity (LLVA), ocular parameters, demographic characteristics, systemic variables, and OCTA metrics (foveal avascular zone area, vessel density [VD] and geometric perfusion deficit in the superficial capillary plexuses [SCP] and [DCP]). Logistic regression prioritized variables with pathophysiologic relevance while minimizing risk of collinearity. Receiver operating characteristic (ROC) curves assessed whether DCP OCTA metrics improved discrimination beyond a clinical model with traditional risk factors. Over one year, 34 eyes (24.8%) experienced one or more complications. Multivariate analysis including DR severity, DCP VD, and LLVA identified higher baseline DR severity (OR, 5.77; 95% CI: 1.93 to 17.27; P = 0.002) and lower DCP VD (OR, 0.59; 95% CI: 0.36 to 0.95; P = 0.031) as significant predictors. Adding DCP VD to the clinical model significantly improved discrimination. These findings support DCP OCTA metrics as capillary-level biomarkers for risk stratification in referable DR and highlight the need for larger longitudinal studies to confirm clinical utility.\n\nID: 42396530\nTitle: Sigma1 Receptor Activation Confers Durable Neuroprotection Following Neonatal Ischemic Retinal Injury.\nAbstract: Retinopathy of prematurity (ROP) remains a leading cause of childhood blindness. Although current therapies effectively suppress pathological neovascularization, many patients continue to exhibit persistent visual dysfunction despite regression of active disease, highlighting an unmet need for neuroprotective interventions. Sigma 1 receptor (Sig1R), an endoplasmic reticulum-mitochondrial chaperone and regulator of cellular stress responses, has emerged as a promising therapeutic target in neurodegenerative and retinal diseases. Here, we investigated whether Sig1R activation confers sustained neuroprotection following neonatal ischemic retinal injury. Wild-type and Sig1R knockout mice were subjected to oxygen-induced retinopathy (OIR) and treated systemically with the high-affinity Sig1R agonist (+)-pentazocine [(+)-PTZ]. Retinal structure and visual function were assessed longitudinally through 20 weeks of age using visual acuity, contrast sensitivity, electroretinography (ERG), pattern ERG (PERG), spectral-domain optical coherence tomography (SD-OCT), and histological analyses. Chronic Sig1R activation significantly preserved visual acuity, contrast sensitivity, rod- and ganglion cell-mediated retinal function, retinal ganglion cell survival, and inner retinal architecture in OIR mice. These protective effects were abolished in Sig1R-deficient mice, demonstrating a requirement for Sig1R in mediating neuroprotection. Mechanistically, Sig1R activation reduced apoptotic signaling, attenuated oxidative and nitrosative stress, improved mitochondrial respiratory function, and enhanced endogenous antioxidant pathways. Collectively, these findings demonstrate that Sig1R activation provides durable, receptor-dependent neuroprotection following neonatal ischemic retinal injury by coordinating redox, mitochondrial, and cell-survival pathways. These results identify Sig1R as a promising therapeutic target for preserving retinal neuronal integrity and long-term visual function in retinopathy of prematurity.\n\nID: 42395017\nTitle: Effect of Korean red ginseng on deep capillary plexus parameters in diabetic retinopathy: A prospective, randomized, double-blind clinical trial.\nAbstract: This prospective, randomized, double-blind clinical trial aimed to evaluate the effects of Korean Red Ginseng (KRG) extract on the retinal microvascular parameters in patients with diabetic retinopathy (DR). Patients with mild to moderate non-proliferative DR were randomized to receive KRG extract or placebo for 90 days. Outcomes included changes in the best-corrected visual acuity (BCVA), intraocular pressure (IOP), central macular thickness (CMT), and optical coherence tomography angiography (OCTA) parameters, including the foveal avascular zone, vessel length density (VLD), and perfusion index (PI) in the superficial and deep capillary plexuses (SCP and DCP, respectively). The incidence of proliferative DR or diabetic macular edema (DME) was also monitored. Twenty-four patients were enrolled and 23 completed the study. The baseline BCVA, IOP, CMT, and OCTA parameters were comparable between the groups (all p\u00a0>\u00a00.05). No significant changes were observed in BCVA, CMT, DR severity stage, or incidence of DME over the 3-month follow-up period in either group. Significant group\u00a0\u00d7\u00a0time interaction effects were observed for inferior DCP VLD (p\u00a0=\u00a00.011) and for PI in the superior (p\u00a0=\u00a00.044) and inferior (p\u00a0=\u00a00.026) DCP regions. No significant interaction effects were identified for SCP parameters or other DCP subfields. No adverse events were reported. KRG extract was associated with short-term, region-specific changes in OCTA-derived DCP perfusion metrics over 3 months. These findings reflect alterations in OCTA-derived microvascular parameters and do not establish modification of clinical outcomes such as DR progression or the development of DME.

This study assessed the impact of subretinal drusenoid deposits (SDDs) on EZ-based quantitative metrics in nonneovascular age-related macular degeneration (AMD). Spectral-domain optical coherence tomography volumes from 83 eyes (44 patients) with SDDs from the Amish Eye Study were analyzed. A semi-automated deep learning-based segmentation with manual correction delineated the inner EZ, inner RPE, and inner SDD surfaces. Photoreceptor outer segment (POS; EZ-SDD) thickness, SDD thickness, and EZ-RPE thickness were measured within Early Treatment Diabetic Retinopathy Study subfields. The proportional SDD contribution to EZ thickness (SDD/EZ ratio) and longitudinal changes over 2 years were evaluated. Mean POS and EZ-RPE thickness were 24.4 \u00b1 4.3 \u00b5m and 26.3 \u00b1 5.1 \u00b5m, respectively. Mean SDD thickness was 1.95 \u00b1 2.5 \u00b5m, increasing to 6.75 \u00b1 3.9 \u00b5m in SDD-dominant regions. The SDD/EZ ratio averaged 6.9% \u00b1 6.7% and exceeded 10% in 24% of eyes, mainly in the outer macular ring. Over 2 years, POS thickness and EZ-RPE thickness decreased significantly (\u0394POS = -2.59 \u00b5m; \u0394EZ-RPE = -2.86 \u00b5m; P = 0.002, P = 0.006, respectively) with a strong correlation (R2 = 0.79), which weakened in eyes with high SDD burden (R2 = 0.16). SDDs cause variable inflation of EZ-RPE thickness, particularly perifoveally. While EZ-RPE thinning reflects POS loss, its reliability may decrease with substantial SDDs. POS-specific metrics and SDD/EZ ratios may improve EZ-based endpoints in AMD trials.\n\nID: 42390169\nTitle: M\u00fcller Glia-Exclusive CLRN1 Expression Drives Non-Cell-Autonomous Photoreceptor Degeneration in Usher Syndrome Type 3A.\nAbstract: Usher syndrome type 3A (USH3A), caused by CLRN1 mutations, leads to progressive deaf-blindness. Although CLRN1 expression has been localized to M\u00fcller glia (MG), the pathogenic mechanisms linking glial CLRN1 deficiency to photoreceptor death remain undefined. We utilized a novel large-animal model to elucidate cell-type-specific pathogenesis at single-nucleus resolution. CLRN1-/- rabbits were generated via CRISPR/Cas9. Retinal phenotyping included longitudinal optical coherence tomography (OCT), electroretinography (ERG), and histology for up to 3 years. Single-nucleus RNA sequencing (snRNA-seq) was performed at a pre-symptomatic stage (10 months, n = 3/genotype). Differentially expressed genes (DEGs) were identified using pseudobulk DESeq2 and validated via immunofluorescence. CLRN1-/- rabbits exhibited progressive outer nuclear layer thinning and delayed ERG responses starting after 20 months, mimicking human clinical kinetics. The snRNA-seq revealed that CLRN1 is exclusively expressed in a discrete subset (\u223c24%) of MG. Mutant MG exhibited transcriptomic downregulation of the adherens junction component CTNNA2, which was validated at the protein level by immunofluorescence staining. Photoreceptors exhibit extensive non-cell-autonomous dysregulation (232 rod and 68 cone DEGs) characterized by loss of the cone synaptic organizer TENM2 and rod-specific splicing dysregulation (CWF19L2). Concurrently, inner retinal neurons mounted a robust proteostatic response via HSP90 family upregulation (HSP90AB1, HSP90AA1, HSP90B1), a defensive signature absent in vulnerable photoreceptors. Our findings suggest an \"anchor-shield\" mechanism: MG CLRN1 loss compromises the outer limiting membrane (OLM) adhesion complex (\"anchor\"), and photoreceptors lack the proteostatic response (\"shield\") seen in resilient inner neurons. Restoring CLRN1 in M\u00fcller glia or implementing photoreceptor neuroprotection represents promising therapeutic strategies for USH3A.\n\nID: 42390160\nTitle: The Role of Nrf2 in SIRT1-Mediated RGC Neuroprotection in Traumatic Optic Neuropathy.\nAbstract: Traumatic optic neuropathy (TON), often occurring in traumatic brain injury (TBI) patients, is characterized by optic nerve damage, retinal ganglion cell (RGC) loss, and vision loss. Upregulation of sirtuin 1 (SIRT1), a nicotinamide adenine dinucleotide (NAD)-dependent deacetylase, reduces RGC loss and vision deficits in TON models, but mechanisms underlying these effects are not well understood. This study examined if Nrf2, a transcription factor that regulates antioxidant enzymes, helps mediate neuroprotective effects of SIRT1 in TON. Wild-type (WT) and Nrf2-deficient mice received an intravitreal injection with adeno-associated virus type 2 (AAV2) expressing an RGC-selective promoter-driven human SIRT1, green fluorescent protein (GFP), or Nrf2. TON was induced by repetitive mild head impacts, and vision was assessed by optokinetic responses (OKRs). RGCs from isolated retinas were immunolabeled with Brn3a antibodies and counted to quantify Brn3a+ RGC numbers. TON resulted in decreased Brn3a labeling and decreased OKR scores in AAV2/synuclein gamma (SNCG)/GFP-injected WT mice as compared with unimpacted mice; AAV2/SNCG/SIRT1 treatment attenuated this loss. This protective effect was absent in Nrf2-deficient mice subjected to TON, as these mice had significant decreases in Brn3a-labeled cells and OKR scores whether they received AAV2/SNCG/GFP or AAV2/SNCG/SIRT1 therapy. AAV2/SNCG/Nrf2-injected WT mice exhibited similar decreases in Brn3a labeling and OKR scores as AAV2/SNCG/GFP-injected WT mice. Nrf2 is implicated as an important downstream effector of SIRT1-mediated therapeutic effects given that Nrf2-deficient mice are unable to recapitulate the neuroprotective effects of AAV-based SIRT1 gene therapy. However, Nrf2 is not sufficient to induce similar neuroprotective effects when overexpressed selectively in RGCs. Results of this study define an important mechanism of SIRT1 gene therapy mediating RGC neuroprotection.\n\nID: 42387629\nTitle: Insect phototransduction: illuminating pathways to precision Pest management.\nAbstract: Insects rely on their visual systems to perform critical behaviors such as host location and phototaxis, and phototransduction, the conversion of photons into electrical signals, constitutes the core mechanism underlying visual function. Most research focuses on model insects like fruit flies, while common agricultural pests remain underexplored. This review integrates current knowledge of insect visual phototransduction to identify molecular and neural targets for precision pest management. This review systematically outlines the complete phototransduction pathway in insect vision: compound eyes and visual lobes exhibit structural specialization adapted to different ecological niches; rhodopsin synthesis and opsin diversity form the molecular foundation; the 'opsin-phospholipase-transient receptor potential channels' pathway and histamine-acetylcholine dual-transmitter branching achieve signal cascading and functional differentiation. Current research has led to the development of three environmentally friendly pest control technologies, first, vision-based traps that capture pests by optimizing spectral, polarization, and color properties of materials; second, molecular tools such as CRISPR/Cas9, RNA interference, and anti-sense DNA to target visual genes; and third, multimodal devices that combine sensory synergy with smart optical technologies for physical interception. Existing vision-based pest control methods still face significant limitations in field applications and tend to be highly species-specific. Future efforts should integrate basic vision research with practical applications to drive the transition from chemical dependency to ecologically friendly and precision pest management. \u00a9 2026 Society of Chemical Industry.\n\nID: 42386595\nTitle: Teprotumumab-associated persistent unilateral hearing loss in dysthyroid optic neuropathy: a case report with review of the literature.\nAbstract: We report a case of severe thyroid eye disease (TED) complicated by dysthyroid optic neuropathy (DON) in a 55-year-old woman with Graves' disease. Despite insufficient response to high-dose intravenous steroid therapy, teprotumumab led to marked improvement in proptosis, orbital inflammation, and visual function. However, treatment was associated with progressive and persistent sensorineural hearing loss after completing eight infusions. Auditory symptoms began after the fifth infusion with intermittent aural fullness and sound reverberation, progressing to mild down-sloping sensorineural hearing loss. Nine days after the final infusion, the four-frequency pure-tone average (PTA4) was 21.25 dB hearing level (HL) in the right ear and 27.50 dB HL in the left ear. Despite initiation of oral prednisolone therapy (40 mg/day with tapering), progressive hearing loss was observed in the right ear, particularly in the low- to mid-frequency range (250-2,000 Hz), with thresholds worsening to 90 dB HL. At twenty days after the final infusion, PTA4 had increased to 75.00 dB HL in the right ear and 31.25 dB HL in the left ear. Serial audiometric assessments at 107, 128, and 198 days after the final infusion demonstrated no recovery. The patient's history of sudden sensorineural hearing loss suggests increased susceptibility to teprotumumab-associated ototoxicity. This case underscores the importance of individualized risk assessment, careful audiologic monitoring, and shared decision-making when balancing visual recovery against the risk of potentially irreversible auditory toxicity.\n\nID: 42380906\nTitle: Assessment of real-life visual outcomes and treatment efficacy of diabetic macular edema in patients with type 2 diabetes.\nAbstract: Diabetic macular edema (DME) is a major cause of vision loss in individuals with diabetes. This study evaluated the long-term visual prognosis of patients with type 2 diabetes (T2D) by assessing real-world DME treatment outcomes. Patients with T2D and DME at Oulu University Hospital during 2010-2023 were included. The effect of DME intervention (anti-VEGF-agents, macular laser or both, intravitreal corticosteroids, observation) was evaluated by changes in visual acuity (VA) and residual edema. The dataset comprised additional variables, including age, sex, age at T2D diagnosis, timing of onset for diabetic retinopathy (DR) and DME, DR severity, glucose levels, other comorbidities, occurrences of treatment interruption, and adverse effects related to intravitreal therapy. Of 549 screened patients with T2D, 1145 DME episodes in 355 patients (560 eyes) were included. Mean ages at T2D, DR, and DME diagnosis were 51.0, 61.7, and 66.4 years, respectively. Mean HbA1c at DME treatment initiation was 64.3 mmol/mol; 93.0% had hypertension medication and 47.6% had diabetic nephropathy. DME was most treated with anti-VEGF injections alone (55.3%) or combined with laser (20.4%), yielding mean VA improvements of 3.8 [3.0-4.6] and 3.6 [2.5-4.6] ETDRS letters (both p\u2009<\u20090.001), respectively. Intravitreal corticosteroids (3.1%) resulted in a gain of 4.3 [1.2-7.4] letters (p\u2009=\u20090.014), whereas macular laser alone (12.8%) and observation (8.3%) showed no significant effect. Residual edema occurred in 38.1% (anti-VEGF), 43.2% (combination), 54.7% (observation), and 80.6% (corticosteroid) of cases. Adverse events related to any DME treatment were rare. Despite recurrent episodes of DME, most patients with T2D experienced improvement in visual acuity. Anti-VEGF agents alone or combined with macular laser appeared to be beneficial in terms of both visual gain and reduction of edema.\n\nID: 42379280\nTitle: Metabolomics approach using UHPLC/QE-MS for the mechanism of He Xue Ming Mu tablets on non-proliferative diabetic retinopathy.\nAbstract: He Xue Ming Mu Tablets (HXMMT) are traditional Chinese medicine formulations used in clinical practice for the treatment of diabetic retinopathy. The primary purpose of this article is to illuminate the potential mechanistic pathways underlying its therapeutic efficacy in non-proliferative diabetic retinopathy. UHPLC/QE-MS was used for plasma metabolomics analysis of 10 HXMMT-treated NPDR patients, 10 untreated NPDR patients, and 10 healthy controls. To identify differential metabolites, principal component analysis (PCA) for visualizing metabolic variation and hierarchical clustering for grouping samples by metabolic profiles, were combined with Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis to investigate related biological pathways. Intraocular pressure (IOP), best-corrected visual acuity (BCVA), central foveal thickness (CFT), and inflammatory/angiogenic markers (IL-6, TNF-\u03b1, VEGF, Ang-2) were assessed, with correlations analyzed between altered metabolites and clinical indices. HXMMT significantly improved macular edema, reduced fundus hemorrhage, and attenuated retinal inflammation (P\u202f<\u202f0.05). Metabolomic profiling identified a total of 813 plasma metabolites, and 283 metabolites exhibited distinct expression patterns that effectively discriminated NPDR patients from healthy controls, while 39 metabolites were found to distinguish between untreated NPDR patients and those who received HXMMT treatment. Consequently, 12 key metabolites showed significant covariance with clinical parameters of NPDR (P\u202f<\u202f0.05), suggesting their potential role as critical mediators in the pharmacodynamic mechanism of HXMMT. HXMMT exerts therapeutic effects on NPDR by targeting 12 plasma metabolites, particularly via the glycerophospholipid metabolic axis, providing a mechanistic basis for its clinical use.\n\nID: 42378082\nTitle: Quantitative optical coherence tomography angiography analysis of retinal capillary plexuses in diabetic eyes: Impact of phakic and pseudophakic status.\nAbstract: Optical coherence tomography angiography (OCTA) has revolutionized the evaluation of retinal microvasculature by enabling noninvasive quantification of capillary networks and the foveal avascular zone (FAZ). Diabetic retinopathy (DR) is associated with progressive microvascular rarefaction, but the effect of lens status on OCTA-derived vascular metrics remains underexplored. In this prospective observational study, 107 diabetic eyes imaged between March and August 2025 at Drashti Netralaya underwent high-resolution OCTA using the Heidelberg Spectralis platform. OCTEVA software enabled automated segmentation of the superficial (SCP), intermediate (ICP), and deep capillary plexuses (DCP). Quantitative measurements included vessel area density, branchpoint density, fractal dimension, and FAZ area. Lens status was classified as phakic or pseudophakic. Between-group comparisons were performed using Mann-Whitney U tests with Holm correction for multiple comparisons, and Cohen's d was calculated for effect size. Pseudophakic eyes exhibited significantly reduced vascular density (SCP: 44.7 \u00b1 6.2% vs 48.5 \u00b1 5.9%, P = 0.004; ICP: 33.8 \u00b1 4.5% vs 36.7 \u00b1 4.3%, P = 0.008; DCP: 34.2 \u00b1 4.9% vs 37.9 \u00b1 5.1%, P = 0.005) and lower fractal dimension (SCP: 1.39 \u00b1 0.06 vs 1.42 \u00b1 0.05, P = 0.011). FAZ area was significantly larger in pseudophakic eyes (0.37 \u00b1 0.09 mm\u00b2 vs 0.32 \u00b1 0.08 mm\u00b2, P = 0.018). Central macular thickness was slightly increased in pseudophakic eyes but not statistically significant (P = 0.07). Pseudophakic eyes demonstrate measurable microvascular compromise and FAZ enlargement compared with phakic eyes, reflecting advanced diabetic disease burden. Lens status should be considered when interpreting OCTA biomarkers in DR research and clinical assessment.\n\nID: 42377658\nTitle: Ginkgo biloba extract as a retinal protective agent: a systematic review of preclinical experiments.\nAbstract: Ginkgo biloba extract (EGb), a complementary and alternative medicinal option, has gained extensive application in addressing conditions like cerebrovascular and peripheral vascular disorders. We aim to assess the neuroprotective efficacy of EGb for retinal disorders and to clarify its potential mechanisms of action through a systematic review. We searched original literature about laboratory experiments from four databases which were released until April 2024. The methodological quality of included in vivo studies was assessed using the SYRCLE risk of bias tool. The results showed that out of the 398 studies initially collected, 26 articles met the requirements for full-text review. 20 of them presented in vivo data, 2 detailed both in vitro and in vivo evidence, and 4 were in vitro experiments. Results demonstrated the protective effects of EGb against several retinal disorders, including retinal ganglion cell injury, retinal degeneration, ischemia, vitreo- or pre-retinal proliferative disorder, uveitis, and diabetic retinopathy. Based on SYRCLE's evaluation of bias risk, the in vivo studies' quality scores varied from 4 to 7 points. The data indicated that EGb preserved visual function by maintaining retinal morphology and structure in preclinical models. Its action mechanism may be associated with suppressing apoptosis, attenuating oxidative stress, reducing inflammation, inhibiting angiogenesis, and suppressing proteolysis. These preclinical findings suggest that EGb may be a promising neuroprotective agent for retinal disorders. However, the methodological limitations of the included studies necessitate cautious interpretation; to demonstrate the effectiveness and safety of EGb, more extensive clinical randomized controlled trials are required.\n\nID: 42373197\nTitle: Safety and efficacy of biosimilar aflibercept MYL-1701P in diabetic macular oedema: 20-week extension results following the INSIGHT pivotal trial.\nAbstract: To evaluate the safety, efficacy and immunogenicity of biosimilar aflibercept (MYL-1701P) in participants with diabetic macular oedema who completed the 52-week global phase III trial and were enrolled in an extension study. In a 20-week, multicentre, open-label extension study at 15 sites in India, safety and efficacy were assessed in 52 participants who received three doses (2\u2009mg intravitreal) of MYL-1701P either continuing on MYL-1701P (continuation arm) or switching to it from reference aflibercept (switch arm). The primary outcome was safety, assessed by the incidence of treatment-emergent adverse events (TEAEs). The secondary outcome was efficacy and included change in visual acuity (best corrected visual acuity (BCVA) based on Early Treatment Diabetic Retinopathy Study (ETDRS) letters) and central subfield thickness ((CST); by spectral-domain optical coherence tomography). Of the 52 participants enrolled, 46 completed week 76. Participants in both arms had comparable baseline characteristics. Incident TEAEs were noted in 9/29 participants in the continuation arm and 7/23 in the switch arm. No participant reported treatment-induced or boosted antidrug antibodies. The adjusted mean difference in BCVA change between baseline of parent study and week 76 (end of extension study) was -1.20 (2.95) ETDRS letters (90%\u2009CI -6.15 to 3.75) and from baseline of extension study to week 20 (week 76-parent study) was 1.59 (1.1) (90%\u2009CI -0.26 to 3.43). The adjusted mean difference in CST from baseline of parent study to week 76 was -15.9 (38.07) \u00b5m (90%\u2009CI -80.47 to 48.62) and from baseline of extension study to its end was 13.53 (16.13) \u00b5m (90%\u2009CI -13.86 to 40.92). The study had certain limitations, including participation from one geographical area, an open-label design and small number of participants. Despite the limited number of exposures in the switch arm, it still constituted a reasonable exposure, and similar safety, efficacy and immunogenicity profiles were observed between those who continued receiving MYL-1701P and those who switched from reference aflibercept to MYL-1701P in the 20-week extension study of the pivotal trial.

A rat DR model was established and treated with BBR, and histological analyses, including hematoxylin and eosin staining, Nissl staining, and immunofluorescence, were executed to evaluate tissue changes. Core target genes were identified using the GeneCards database, Venn diagram analysis, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment, protein-protein interaction networks, and molecular docking. Validation of key genes was performed via reverse transcription-quantitative polymerase chain reaction (RT-qPCR), Western blot, and RNA interference. BBR improved retinal morphology, reduced edema, and restored the arrangement of retinal ganglion cells in DR rats. BBR significantly reduced the levels of pyroptosis markers such as IL-1\u03b2 and IL-18, which were elevated in DR. Network pharmacology identified 10 hub genes, with six genes (JUN, STAT3, AKT1, TP53, IL-1B, EGFR) further analyzed. BBR reversed DR-induced upregulation of JUN, STAT3, and AKT1 at both the mRNA and protein levels, as confirmed by RT-qPCR and Western blot. Silencing these genes enhanced cell viability and amplified BBR's protective effects. Altogether, BBR alleviates retinal inflammation and pyroptosis in diabetic retinal ganglion cells by targeting JUN, STAT3, and AKT1, providing insights into its therapeutic potential for DR.\n\nID: 42461929\nTitle: Long-Acting RXR Agonism Preserves Retinal Function and Modulates Inflammation in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss and is associated with reduced nuclear retinoid X receptor (RXR) activity. Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy.\n\nID: 42460327\nTitle: Neurovascular unit uncoupling in diabetic retinopathy: molecular mechanisms and stage-adapted therapeutic strategies.\nAbstract: Diabetic retinopathy (DR) is a major neurovascular complication of diabetes and remains a leading cause of vision loss among working-age adults worldwide. Although DR has traditionally been classified as a microvascular complication, it is now increasingly recognized as a neurovascular degenerative disorder involving coordinated injury to neuronal, glial, vascular, and extracellular matrix components of the retinal neurovascular unit (NVU). The NVU provides the structural and functional basis for coupling neuronal activity to local blood flow and for maintaining retinal immune and barrier homeostasis. In diabetes, chronic hyperglycemia, oxidative stress, inflammation, metabolic dysregulation, impaired vascular endothelial growth factor (VEGF)/angiopoietin-Tie (Ang/Tie) signaling, abnormal intercellular communication, and epigenetic memory progressively disrupt the coordinated interactions among NVU components, leading to neurovascular uncoupling. This concept helps explain why retinal functional abnormalities and neurodegenerative changes may precede clinically visible vascular lesions. In this review, we summarize cell-specific NVU alterations and the molecular mechanisms that drive neurovascular uncoupling in DR. We also discuss how this framework may support earlier diagnosis, mechanism-based phenotyping, and stage-adapted treatment strategies. Established therapies, including anti-vascular endothelial growth factor (anti-VEGF) agents, corticosteroids, and angiopoietin-2 (Ang-2)/Tie-2-directed vascular stabilization, are considered together with investigational approaches targeting oxidative stress, inflammation, neuroprotection, metabolic reprogramming, epigenetic regulation, and drug delivery. Reframing DR as a diabetes-driven disorder of early NVU uncoupling may help shift clinical thinking from late vascular rescue toward mechanism-based neurovascular protection, precision phenotyping, and stage-adapted intervention.\n\nID: 42460019\nTitle: The influence of magnesium ions on the electrophysiological, analgesic, and BDNF-induced neuromodulation of morphine effects in diabetic rats.\nAbstract: Neuropathic pain is difficult to treat due to the involvement of multiple signaling pathways, including increased expression of sodium channels, decreased expression of potassium channels, heightened neuronal excitability from the activation of N-methyl-D-aspartate receptors (NMDARs), nerve damage leading to changes in neurotrophic factor levels, and reduced opioid efficacy. As a result, the treatment of neuropathic pain often requires a multifaceted approach. It has been shown that magnesium ions (Mg2+), which act as physiological antagonists of NMDARs, can augment opioid analgesia in chronic pain. The aim of this study was to assess the influence of Mg2+ on the electrophysiological, analgesic, and brain-derived neurotrophic factor (BDNF)-induced neuromodulation of the morphine profile in diabetic rats. Diabetes in male Wistar rats was induced by a single intramuscular injection of streptozotocin (STZ). The Plantar Test was used to assess the effect of Mg2+ and morphine co-treatment on STZ-induced hyperalgesia, expressed as increased warm sensitivity of the experimental rat hind paw. Ex vivo whole-cell recordings from ventrolateral periaqueductal gray (vlPAG) neurons were conducted to evaluate the frequency of action potentials evoked by incremental depolarizing current steps (current-clamp, 1-s steps). To assess glutamatergic signaling, neurons were voltage-clamped to measure NBQX-sensitive current at -70\u00a0mV and NMDA-evoked currents during depolarization in the presence of NMDA/glycine. Changes in BDNF concentrations in PAG structures were measured using an enzyme-linked immunosorbent assay. The results of our study suggest that although magnesium sulfate shows limited analgesic properties when administered alone, it can significantly enhance opioid efficacy when used as an adjunct. Moreover, the co-administration of morphine with magnesium sulfate resulted in a greater reduction in NMDA-evoked currents in diabetic rats compared to either agent alone. Overall, our findings support the concurrent use of Mg2+ and morphine in the treatment of neuropathic pain as a mechanism-informed adjunct strategy.\n\nID: 42459426\nTitle: The relevance of cannabinoid receptor 2 in the central nervous system: an update over the last 3 years.\nAbstract: The endocannabinoid system is a neuromodulatory network regulating synaptic plasticity, neuronal activity, and neuroinflammatory responses in both the central and peripheral nervous systems. The endocannabinoid system comprises endogenous ligands, termed endocannabinoids, and two principal receptors, cannabinoid receptor type 1 and type 2 (CB1R and CB2R). While CB1R is predominantly associated with the central nervous system and mediates the psychotropic effects of cannabis-derived compounds, CB2R was initially considered mainly peripheral. However, growing evidence over the last decades has highlighted a pivotal role for CB2R in central nervous system homeostasis and pathology. Importantly, the lack of psychotropic effects associated with CB2R signaling has positioned this receptor as a promising therapeutic target for several brain-related disorders, including neuroinflammatory, neurodegenerative, neuropsychiatric, and neurovascular conditions. Here, we provide a structured review of experimental studies published over the last 3 years investigating CB2R modulation in the central nervous system, with a particular focus on disease mechanisms and emerging therapeutic strategies.\n\nID: 42459363\nTitle: Inhibiting the uPAR/FPR1 interactions reduces blood-retinal barrier breakdown and improves retinal function in a rat model of diabetes.\nAbstract: Diabetic retinopathy (DR) is a leading cause of blindness characterized by early neurovascular damage driven by hyperglycemia-induced mechanisms, including inflammation. The system composed of the urokinase-type plasminogen activator (uPA) and its receptor (uPAR) has previously emerged as a potential regulator of the pro-inflammatory events in DR, possibly through the interaction of uPAR with its lateral partners, such as formyl peptide receptors (FPRs). This study explored whether the inhibition of uPAR/FPR1 crosstalk may reduce early neurovascular alterations in DR by targeting inflammation. To this aim, the new FPR1 antagonist N-19004 was tested in a rat model of streptozotocin-induced diabetes. N-19004 was administered subcutaneously for 7\u202fdays at 1\u202fmonth from diabetes onset. Immunofluorescence, RT-qPCR, Western blot and Evans blue perfusion were performed to evaluate the effects of N-19004 on inflammation, reactive gliosis, blood-retinal barrier (BRB) integrity and apoptosis. In addition, electroretinogram (ERG) was used to assess N-19004 efficacy on retinal function. N-19004 inhibited the activation of inflammation-related transcription factors, including nuclear factor kappa-light-chain-enhancer of activated B cells and signal transducer and activator of transcription 3, leading to reduced interleukin-1\u03b2 and tumor necrosis factor-\u03b1 expression. The attenuation of inflammatory processes resulted in reduced glial activation, as indicated by lower glial fibrillary acidic protein expression and M\u00fcller cell gliosis. The anti-inflammatory activity of N-19004 was accompanied by decreased BRB breakdown, as demonstrated by N-19004-mediated reduction of vascular endothelial growth factor, increased levels of tight junction components and diminished vessel leakage. The amelioration of BRB integrity was associated with reduced activation of caspase 3 and partial preservation of scotopic ERG a- and b-wave amplitudes, thereby improving retinal viability and function in N-19004-treated STZ rats. These results support the possible involvement of uPAR/FPR1 interactions in the regulation of DR-related inflammation and suggest a novel therapeutic target for the management of the early phases of disease.\n\nID: 42458952\nTitle: Syntaxin-4 at the Crossroads of Synaptic Plasticity and Neurodegeneration: From Molecular Mechanisms to Biomarker and Therapeutic Potential.\nAbstract: Syntaxin-4 (Stx4), a member of the Qa-SNARE protein family, is a pivotal regulator of membrane trafficking. Stx4 is predominantly localized at the postsynaptic membrane of neurons and in glial cells, where it is essential for synaptic plasticity and the maintenance of neuronal homeostasis. Stx4 facilitates the activity-dependent exocytosis of glutamatergic receptors, thereby governing the balance between Long-Term Potentiation (LTP) and Long-Term Depression (LTD). Emerging evidence suggests that dysregulation of Stx4 is intricately linked to the pathogenesis of neurodegenerative diseases. In Alzheimer's disease, Stx4 is involved in synaptic dysfunction and cognitive impairment through its interactions with amyloid-\u03b2 (A\u03b2) and tau pathologies, affecting receptor recruitment at dendritic spines. In Parkinson's Disease (PD), Stx4 contributes to \u03b1-synuclein proteostasis, dopaminergic signaling, neuroinflammation, and the maintenance of blood-brain barrier integrity. While its presence in cerebrospinal fluid highlights its potential as a candidate biomarker for these diseases, further validation is required to establish clinical utility. This review summarizes current mechanistic insights into Stx4's multifaceted roles in the neurodegenerative disorders and explores the therapeutic prospects of targeting Stx4-mediated pathways due to its translational potential.\n\nID: 42458355\nTitle: Socioeconomic gradients in hypertension prevalence and management: a cross-sectional study.\nAbstract: Despite advances in hypertension treatment, achieving optimal blood pressure control remains a major public health challenge. Socioeconomic status (SES) may influence hypertension management; however, evidence on its associations with pharmacotherapy, lifestyle modification, and self-management education remains limited. In this study, the association between SES and hypertension-related outcomes in the Republic of Korea was investigated. In this nationwide cross-sectional study, data from the 2023 Korea Community Health Survey were analyzed, comprising 231,584 and 228,608 adults for educational attainment and household income analyses, respectively. Hypertension-related outcomes included diagnosed hypertension, pharmacotherapy, lifestyle modification, and self-management education. Crude and age- and sex-adjusted rates were calculated, followed by multivariable logistic regression analyses, adjusting for potential confounders. Overall, the prevalence of diagnosed hypertension was 31.3%. Among participants with hypertension, the rates of pharmacotherapy, lifestyle modification, and self-management education were 95.9%, 23.8%, and 15.5%, respectively. The multivariable analyses showed a dose-response relationship between SES and outcomes: participants with primary school education or less had higher odds of diagnosed hypertension (odds ratio, 1.79; 95% confidence interval, 1.71-1.88) and pharmacotherapy use (2.04; 1.67-2.50) but lower odds of lifestyle modification engagement (0.47; 0.43-0.50) and receiving self-management education (0.34; 0.31-0.38) compared to those with college degree or higher. Notably, these socioeconomic gradients remained robustly consistent across all strata, while significantly steeper gradients were observed among females and younger adults (<\u200965\u00a0years). Analyses by household income showed similar patterns of associations, although with slightly weaker magnitudes. Lower SES was associated with a higher prevalence of diagnosed hypertension and pharmacotherapy use but lower participation in lifestyle modifications and self-management education. Strengthening tailored self-management education and lifestyle modification support for socioeconomically disadvantaged groups may be an important strategy to reduce hypertension-related disparities.\n\nID: 42453573\nTitle: Multi-target antidiabetic and organ-protective effects of a polyherbal ethanol extract in STZ-induced diabetic rats.\nAbstract: In diabetes mellitus conditions, hyperglycemia leads to oxidative stress, inflammation, and \u03b2-cell dysfunction, and traditional pharmacotherapy targets only a single pathway, which gives suboptimal outcomes and drug-related problems. A novel, polyherbal ethanol extract (PHE) formulation from Tinospora cordifolia, Commiphora wightii, Cinnamomum zeylanicum, and Paeonia officinalis was evaluated for antidiabetic and organ-protective effects at different levels for multi-targeting in a streptozotocin (STZ)-induced rat model. Male Wistar rats were made diabetic using intraperitoneal administration of streptozotocin (55\u00a0mg/kg) and randomly segregated into five groups: Normal, STZ-induced diabetic, STZ + PHE (200\u00a0mg/kg/day), Normal + PHE, and STZ + metformin (Met; 300\u00a0mg/kg/day). After 8 weeks of treatment, FBG, HbA1c, insulin, lipid profile, proinflammatory cytokines (TNF-\u03b1, IL-1\u03b2), oxidative stress biomarkers, and liver function markers were determined. Histological examination was performed on liver and pancreatic tissues with H&E staining, along with assessment of pancreatic insulin immunoreactivity. GC-MS analysis was conducted to characterize the phytochemical constituents of PHE. PHE treatment significantly reduced FBG by 33%, HbA1c by 15%, and restored serum insulin levels (+34%) versus untreated diabetics (p < 0.05). Dyslipidemia was corrected, with LDL-C reduced by 30% and HDL-C increased by 46%. Hepatic ALT and AST levels were also attenuated after PHE treatment. Oxidative stress was alleviated, and TNF-\u03b1 and IL-1\u03b2 levels in the liver and pancreas were markedly suppressed. Histology showed preserved hepatocyte integrity and islet morphology, and immunohistochemistry confirmed improved \u03b2-cell integrity and enhanced insulin immunoreactivity. The polyherbal preparation produced impressive control over glycemia, strong antioxidant and anti-inflammatory effects, and protection of liver and pancreatic architecture. These effects translate into its potential as a phytotherapeutic candidate for safely managing diabetes and its complications, warranting further molecular and clinical research.\n\nID: 42452694\nTitle: Evolving Landscape of Regenerative Therapies: Cell-Based and Cell-Free Approaches for Chronic Low Back Pain.\nAbstract: Background: Chronic low back pain (CLBP) is the leading cause of years lived with disability globally, affecting over 600 million individuals. Intervertebral disc degeneration (IVDD) is a principal structural contributor, yet conventional treatments, including pharmacotherapy, physical therapy, and surgical intervention, do not reverse the underlying degenerative pathology. Regenerative medicine has introduced a spectrum of biological therapies for IVDD, including cell-based mesenchymal stromal cell (MSC) therapy, platelet-derived products such as platelet-rich plasma (PRP) and platelet lysate, extracellular vesicle-based approaches using MSC-derived extracellular vesicles (EVs), and secretome-based therapies using MSC-derived secretomes. However, these approaches have largely been studied in isolation, without a unified framework to compare their respective advantages and limitations in CLBP secondary to IVDD. Accordingly, this narrative review aims to provide an integrated and comparative evaluation of these regenerative strategies within a single translational and clinical context. Methods: For this narrative review, PubMed, Scopus, and Web of Science were searched from January 2000 to January 2026 using terms combining regenerative modalities with intervertebral disc degeneration, and chronic low back pain. Randomized controlled trials (RCTs), prospective cohort studies, systematic reviews, and preclinical studies with translational relevance were included. Results: Intradiscal MSC therapy has demonstrated safety across multiple phase I-III trials, but two recent landmark RCTs (RESPINE and the Mesoblast phase III trial) failed to meet primary efficacy endpoints, highlighting the gap between preclinical promise and clinical outcomes. PRP has the largest clinical evidence base, with level II evidence supporting short- to medium-term pain relief for discogenic pain, although standardization remains a critical barrier. Platelet lysate, MSC-derived EVs, and MSC-derived secretomes show compelling preclinical data, including extracellular matrix restoration, anti-inflammatory modulation, and attenuation of nucleus pulposus cell apoptosis, but remain at early translational stages for spinal applications, with no completed RCTs. The hostile disc microenvironment (avascular, hypoxic, acidic, and nutrient-poor) poses unique challenges for all regenerative modalities, differing fundamentally from other musculoskeletal applications. Conclusions: The studies included in this narrative review suggest that no single regenerative modality has yet shown consistent and unequivocal efficacy for CLBP secondary to IVDD across clinical trials. Cell-free approaches offer manufacturing, scalability, and safety advantages over cell-based therapies, but lack clinical validation. Future progress requires standardized preparation protocols, disc-specific delivery systems, patient phenotyping strategies, and rigorously designed comparative clinical trials. This narrative review provides a framework for researchers and clinicians to evaluate these therapies in context rather than isolation.\n\nID: 42449559\nTitle: An acetylated nobiletin derivative alleviates methylglyoxal-induced cognitive impairment and modulates gut microbiota.\nAbstract: Nobiletin, a citrus polymethoxyflavone recognized as a functional food component with diverse health benefits, has been reported to exhibit antioxidant, anti-inflammatory and neuroprotective properties. Methylglyoxal (MG), a highly reactive dicarbonyl compound and precursor of advanced glycation end products, contributes to oxidative stress, tau hyperphosphorylation and amyloid-\u03b2 (A\u03b2) accumulation, which are key events linking diabetes to Alzheimer's disease. In this study, an acetylated derivative of nobiletin, 5-acetoxy-6,7,8,3',4'-pentamethoxyflavone (5-AN), was evaluated for its neuroprotective and gut microbiota-modulating effects against MG-induced Alzheimer-like cognitive deficits in mice. Oral administration of 5-AN (10 and 20\u2009mg\u2009kg-1\u2009day-1 for 13\u2009weeks) improved behavioral performance in MG-treated mice, with the 20\u2009mg\u2009kg-1 group showing significant improvement in spatial learning, recognition memory and anxiety-like behavior. Immunohistochemical and Western blot analyses showed that 5-AN reduced hippocampal tau phosphorylation and A\u03b2 accumulation at the same time as restoring phosphoinositide 3-kinase (PI3K)/Akt/glycogen synthase kinase-3\u03b2 signaling, enhancing brain-derived neurotrophic factor expression and reducing cleaved caspase-3 expression. Gut microbiota analysis showed that MG exposure induced dysbiosis, characterized by reduced Bacteroides_H acidifaciens and increased MG-associated taxa such as Alistipes and Dysosmobacter, whereas 5-AN supplementation significantly reversed these alterations. Functional prediction analysis further indicated that MG-induced dysbiosis was associated with disruptions in neuroimmune-related pathways, including circadian entrainment, Th17 cell differentiation, interleukin-17 signaling and PI3K/Akt signaling, whereas 5-AN supplementation significantly restored these pathways. These findings indicate that acetylated nobiletin may serve as a promising food-derived bioactive compound for mitigating cognitive impairment through coordinated modulation of neuronal function and gut microbiota. \u00a9 2026 Society of Chemical Industry.\n\nID: 42445691\nTitle: Editorial: Synaptic plasticity across the lifespan: mechanisms, adaptation, and vulnerability.\nAbstract: \n\nID: 42444567\nTitle: Medical Treatments for Obesity: What Does the Future Have in Store?\nAbstract: Obesity is a chronic relapsing disease associated with substantial morbidity, mortality, and health care costs. Contemporary obesity pharmacotherapies extend beyond weight reduction, with evidence for improvements across multiple obesity-related complications, supporting a shift toward phenotype-guided, complication-centric care. A systematic literature search of the Medline database using MeSH terms and keywords related to new-generation obesity pharmacotherapy was conducted to identify articles published between 2021 and 2026. Reference lists of relevant reviews were screened to identify additional eligible studies. Phase 2 and 3 clinical trials evaluating emerging obesity pharmacotherapies in adults and reporting outcomes, including weight loss and obesity-related complications, were included. Entero-pancreatic hormone-based therapies targeting GLP-1, GIP, amylin, and glucagon pathways demonstrate substantial efficacy beyond weight reduction. These hormones act through complementary mechanisms regulating appetite, energy balance, and metabolic homeostasis. GLP-1 based agents achieve approximately 10-15% weight loss, whereas agents targeting multiple pathways demonstrate greater efficacy. Tirzepatide, CagriSema, and amycretin achieved weight reductions exceeding 20% and the triple agonist retatrutide produced reductions exceeding 25%. Beyond weight loss, these agents improve glycemia, support diabetes prevention, and produce organ-specific benefits, including reduced cardiovascular events, improved heart failure symptoms, decreased obstructive sleep apnea severity, improvement of metabolic dysfunction-associated steatohepatitis, slowing chronic kidney disease progression, and reduced osteoarthritis-related pain. Next-generation obesity pharmacotherapies represent a major advance in obesity management and support a treat-to-target approach prioritizing improvement in obesity-related complications and metabolic health. Effective implementation will require individualized therapy and attention to long-term safety, access, and equitable delivery of care.\n\nID: 42444353\nTitle: Obesity Remission: A Missing Target in Contemporary Medicine.\nAbstract: Obesity is a chronic disease associated with substantial cardiometabolic, mechanical, and psychosocial burden, contributing significantly to global morbidity and mortality. Despite its impact, therapeutic strategies remain disproportionately conservative, often delaying effective intervention. In contrast, treatment algorithms for other chronic diseases, such as type 2 diabetes and rheumatoid arthritis, have adopted remission-oriented approaches aimed at suppressing disease activity rather than merely attenuating progression. In this context, we propose a remission-oriented paradigm for obesity. Remission is defined as a sustained, multidimensional state characterized by the achievement of clinically meaningful adiposity targets, alleviation of obesity-related complications, restoration of functional capacity, and improvement in psychological well-being. Importantly, remission is conceptualized as a continuum, analogous to glycemic states, and may be maintained with ongoing pharmacotherapy. We further propose an induction-remission-maintenance model that prioritizes early, effective intervention. This framework explicitly acknowledges the chronic nature of the disease of obesity, even in the presence of potent therapies, underscoring the need for ongoing monitoring and long-term disease surveillance. Despite challenges related to access, cost, and long-term adherence, this approach offers a structured, disease-centered model with the potential to improve clinical outcomes and reduce healthcare burden.\n\nID: 42443639\nTitle: Treatment Selection Patterns and Associated Outcomes for Biguanides and SGLT2 Inhibitors in Type 2 Diabetes: A Retrospective Database Study in Japan.\nAbstract: Type 2 diabetes mellitus has multiple treatment options and high healthcare costs. In Japan, DPP-4 inhibitors have been widely used, but since 2022 the pharmacotherapy algorithm has shifted: DPP-4 inhibitors and biguanides for BMI < 25 kg/m   2  , and biguanides and SGLT2 inhibitors for BMI \u2265 25 kg/m   2  . However, real-world factors influencing prescribing decisions between biguanides and SGLT2 inhibitors remain unclear. This study investigates factors influencing the choice between biguanides and SGLT2 inhibitors in clinical practice. We also compare glycemic efficacy and medication persistence while accounting for baseline characteristics. This retrospective cohort study used the Millennium Medical Record Database, primarily capturing care from large hospitals. Adults aged \u2265 18 years who received a first prescription of a biguanide or a SGLT2 inhibitor between July 2019 and April 2023 were included. Patients were categorized as 1st-line or 2nd-line therapy. Confounding was addressed using coarsened exact matching with classification tree modeling. HbA1c changes were analyzed using mixed models for repeated measures, and persistence using Kaplan-Meier methods. A total of 1925 patients were included. In the 1st-line cohort (n\u00a0=\u00a01440), key selection factors were diuretic use, lipid-modifying agents, and baseline HbA1c. At 24 weeks, HbA1c decreased in both groups (biguanide: -1.37 percentage points, 95% CI -1.48 to -1.26; SGLT2 inhibitor: -1.16 percentage points, 95% CI -1.29 to -1.02); the between-group difference was -0.21 percentage points (95% CI -0.38 to -0.04). Persistence at 48 weeks was 47.0% (95% CI 42.7-51.2) for biguanides and 56.2% (95% CI 51.2-61.2) for SGLT2 inhibitors. In the 2nd-line cohort (n\u00a0=\u00a0485), selection factors were baseline HbA1c, BMI, and diuretic use. HbA1c decreased at 24 weeks (biguanide: -2.26 percentage points, 95% CI -2.47 to -2.05; SGLT2 inhibitor: -1.79 percentage points, 95% CI -2.04 to -1.54); the between-group difference was -0.47 percentage points (95% CI -0.80 to -0.15). Persistence at 48 weeks was 51.8% (95% CI 45.2-58.4) for biguanides and 49.4% (95% CI 40.3-58.6) for SGLT2 inhibitors. In Japanese patients with type 2 diabetes, treatment selection was mainly associated with concomitant cardiovascular medication use. BMI influenced choice, particularly in the 2nd-line setting, but was not the predominant determinant. Biguanides were associated with greater HbA1c reductions. In intention-to-treat analyses, persistence over 48 weeks was higher with SGLT2 inhibitors in the 1st-line cohort, while persistence was comparable in the 2nd-line cohort.\n\nID: 42442919\nTitle: Therapeutic targeting of brain bioenergetics in Alzheimer's disease addressing insulin resistance, glucose hypometabolism, and mitochondrial dysfunction.\nAbstract: Alzheimer's disease (AD) is a progressive, age-associated multifactorial neurodegenerative disorder characterised by cognitive decline, synaptic dysfunction, and neuronal loss. Despite over a century of research, effective disease-modifying therapies remain elusive owing to its conundrum pathophysiology. In recent years, AD is increasingly recognised as a complex metabolic disorder characterised by impaired cerebral glucose metabolism, insulin resistance, and mitochondrial dysfunction. These interconnected metabolic disturbances emerge early in the disease state and collectively potentiate other pathologies such as accumulation of amyloid-\u03b2 (A\u03b2) plaques, tau hyperphosphorylation, oxidative stress, neuroinflammation, and synaptic dysfunction, thereby establishing bioenergetic failure as a primary factor governing AD progression rather than a downstream phenomenon. While traditional drug development strategies targeting A\u03b2 have failed in clinical trials (limited to monoclonal antibodies), emerging therapeutic models integrating energy failure, thiamine signalling, and insulin-like growth factor (IGF) signalling as upstream events show significant promise in countering downstream neurodegeneration. This chapter summarises the mechanistic framework linking bioenergetic breakdown to AD pathology, with potential therapeutic opportunities aimed at restoring mitochondrial function, enhancing glucose utilisation, and correcting insulin signalling, further opening new avenues for multimodal interventions and identification of progressive metabolic dysfunction biomarkers to aid diagnostic processes.\n\nID: 42442776\nTitle: The Diverse Role of ipRGCs in Visual Perception Beyond Non-Image-Forming Functions.\nAbstract: The intrinsically photosensitive retinal ganglion cells (ipRGCs) are the third class of photoreceptors apart from rods and cones, containing the photopigment melanopsin and are characterized into different subtypes (M1-M6) that support conscious visual perception. They transmit the light information to the brain through complex circuits serving both non-image-forming and image-forming functions. Of the total population, there are four main ipRGCs, such as M2, M4, M5 and M6 that project substantially to the image-forming visual pathway and target the dorsal lateral geniculate nucleus (dLGN). Recent research has shown that they can modulate the excitatory and inhibitory balance in the primary visual cortex (V1) and thereby boost cortical computations for orientation discrimination. However, the projections of these ipRGCs to the V1 and how they integrate melanopsin signals with the conventional retinal ganglion cells is not yet clear. In this review, we summarize the morphological, physiological and behavioural characteristics of the ipRGC population that project to dLGN and contribute to image processing. Further research to understand how they can potentially enhance sensory representations in the visual cortex would offer therapeutic advantage in several eye diseases causing blindness.\n\nID: 42442566\nTitle: Sleep-related Alzheimer's disease vulnerability in aging: A muscle-metabolic perspective.\nAbstract: Sleep disruption is a hallmark of aging and a plausible driver of Alzheimer's disease vulnerability. Reduced slow-wave sleep, increased fragmentation, and circadian instability may facilitate amyloid-\u03b2 accumulation, tau propagation, neuroinflammation, oxidative stress, and impaired glymphatic clearance. Yet the physiological factors that predispose older adults to unstable sleep remain insufficiently integrated into models of brain aging. This Review advances a sleep-muscle-brain framework in which sarcopenia, sarcopenic obesity, and insulin resistance are conceptualized as modifiable muscle-metabolic conditions that may bias sleep continuity and shape the biological impact of sleep disruption. We examine irisin/FNDC5-BDNF signaling as a hypothesis-generating candidate modifier of metabolic regulation, neurotrophic support, and brain resilience, while emphasizing that direct evidence for a causal role in human sleep regulation remains insufficient. Irisin-related pathways intersect with insulin sensitivity, inflammatory control, and BDNF-dependent synaptic plasticity, all of which are relevant to the physiological context in which sleep disruption may influence Alzheimer's disease pathophysiology. We propose that age-related attenuation of muscle endocrine signaling, together with insulin resistance and low-grade inflammation, may lower the threshold at which sleep fragmentation translates into amyloid/tau dyshomeostasis, glial activation, and network dysfunction. Rather than treating sleep disturbance as an isolated brain-centered risk factor, this framework positions sleep as a biobehavioral hub through which peripheral aging processes can modulate neurodegenerative resilience. The Review integrates evidence from sleep neuroscience, geroscience, metabolism, and neurodegeneration, and identifies experimentally testable predictions. A sleep-muscle-brain perspective may help refine risk stratification and guide multimodal interventions combining sleep optimization, resistance exercise, metabolic targeting, and Alzheimer's disease biomarker monitoring.\n\nID: 42440641\nTitle: Chemical multiplexing in the nervous system: molecular architecture, functional stratification, and pathophysiological plasticity of neuropeptide-classical neurotransmitter cotransmission.\nAbstract: Neurons frequently synthesize both neuropeptides and classical low-molecular-weight neurotransmitters, challenging the historical interpretation of one-neuron-one-transmitter signaling. Rather than representing biochemical redundancy, coexistence reflects a conserved organizational strategy that expands neural coding capacity through chemical multiplexing. Dual vesicular architecture-small clear vesicles for rapid synaptic transmission and large dense-core vesicles for activity-dependent peptide release-creates stimulus-intensity-dependent recruitment of distinct signaling layers. Classical transmitters primarily mediate millisecond-scale synaptic precision, whereas peptides engage slower G-protein-coupled receptor pathways that modulate excitability, plasticity, gene expression, and neuron-glia interactions. Across mammalian circuits, cotransmission regulates oscillatory coherence, learning and memory, motivational states, endocrine integration, sensory gain control, and autonomic balance. Peptidergic signaling is transcriptionally regulated and dynamically remodeled during development, stress, injury, and disease. Dysregulation contributes to chronic pain, addiction, stress-related disorders, epilepsy, cardiovascular dysfunction, and neurodegeneration. Therefore, neuropeptide-neurotransmitter coexistence constitutes a core computational principle of the nervous system, enabling temporal stratification and adaptive plasticity without expanding anatomical connectivity. Understanding chemical multiplexing is essential for linking molecular dynamics to circuit stability and vulnerability in health and disease.\n\nID: 42438453\nTitle: Nicotine combined with estrogen activates protein kinase PKC\u03b9 and TAO, while inhibiting specific MAP kinase pathways in cultured human neurons: an atlas of kinase activities for nicotine use disorder.\nAbstract: Women exhibit sex-specific differences in their responses to nicotine, with sex hormones like estrogen and progesterone playing key roles in nicotine addiction among women. Nicotine disrupts neuronal firing in the brain's reward system, an effect regulated by estrogen. In this study, we hypothesized that exposing human female neurons to both nicotine and estrogen would activate distinct signaling pathways. We treated human female SH-SY5Y neurons with nicotine and estrogen, and compared these to treatments with each substance alone or vehicle control. Using PamGene PamStation technology, we created an atlas of over 500 kinase activities per sample. We found that nicotine modulates MAP kinase pathways in a dichotomous manner. Estrogen showed unique kinase effects, and in combination with nicotine, elicited diverse pathway responses-some kinases becoming hyperactive and others hypoactive. Bioinformatics analysis highlighted several kinases as central to this combined signaling, including PKC\u0269 and TAO, which showed higher kinase activity only with combined treatment and have known links to behavior in rodent models. Conversely, kinases such as the insulin receptor (INSR), HER2, FAK1, and ABL1 exhibited decreased activity under combined treatment. These findings reveal nicotine-specific kinase mechanisms and suggest potential targets for pharmacotherapy aimed particularly at females with high estrogen levels and nicotine use disorder.\n\nID: 42436132\nTitle: Calcineurin/NFAT signaling in the temporal integration of Ca\u00b2\u207a stress in neurodegeneration.\nAbstract: The calcineurin (CaN)/nuclear factor of activated T cells (NFAT) signalling axis is a Ca\u00b2\u207a-responsive pathway that translates intracellular Ca\u00b2\u207a signals into long-term transcriptional programmes. Chronic disruption of intracellular Ca\u00b2\u207a homoeostasis is a convergent feature of neurodegenerative disorders, particularly Alzheimer's disease (AD) and Parkinson's disease (PD). In these conditions, sustained or repetitive Ca\u00b2\u207a elevations promote prolonged activation of the CaN/NFAT pathway, thereby linking Ca\u00b2\u207a dysregulation to persistent cellular responses. In this review, we summarise the molecular organisation and regulation of the Ca\u00b2\u207a/CaN/NFAT pathway and discuss its physiological roles in neurons and glial cells, including synaptic plasticity, neurodevelopment, neurogenesis, and neuroinflammatory responses. We critically examine experimental evidence linking CaN/NFAT signalling to AD and PD, distinguishing direct mechanistic roles from associative and model-dependent findings. Across disease contexts, the CaN/NFAT axis appears to function as a molecular node at which diverse insults, including amyloid-\u03b2 and tau aggregates, \u03b1-synuclein toxicity, mitochondrial dysfunction, and chronic inflammatory cues, converge under conditions of sustained Ca\u00b2\u207a dysregulation. We propose that the pathological relevance of CaN/NFAT lies less in pathway activation per se than in its capacity to convert chronic Ca\u00b2\u207a-dependent stress signals into persistent transcriptional states affecting synaptic integrity, inflammatory tone, and cellular resilience. We conclude by discussing current therapeutic strategies targeting this pathway, their limitations, and the need for temporally and cell-type-specific modulation.\n\nID: 42435947\nTitle: Cyclin-dependent kinases as signaling integrators in cancer: Structural evolution, functional plasticity, and drug discovery.\nAbstract: Cyclin-dependent kinases (CDKs), traditionally recognized for their pivotal role in cell cycle control, have emerged as versatile regulators orchestrating a broader spectrum of biological functions, including transcriptional regulation, immune signaling, metabolic adaptation, and neuronal activity. This review provides a comprehensive synthesis of the structural, functional, and pharmacological landscapes of the CDK family, emphasizing their evolutionary diversification and expanding therapeutic relevance. We explored the conserved architecture of CDK catalytic cores and delineated isoform-specific regulatory adaptations that have evolved through gene duplication and sequence divergence. These evolutionary modifications have enabled the functional repurposing of CDKs across eukaryotic species, which play critical roles in immune modulation, metabolic control, and synaptic plasticity. We also analyzed activation mechanisms, cyclin-binding interfaces, and substrate-recognition features that govern CDK activity. We then examine the pathological consequences of CDK dysregulation in oncogenesis, neurodegeneration, and autoimmune disorders with a focus on drug resistance in current clinical approaches. We further highlighted emerging therapeutic strategies, including transcription-targeting CDK inhibitors, proteolysis-targeting chimeras (PROTACs), covalent inhibitors, and artificial intelligence-guided drug discovery platforms that promise to overcome these challenges. Special attention is given to understudied and emerging CDKs, notably CDK11 (cancer), CDK14 (development), and CDKL5 (neurodegeneration), which represent untapped therapeutic frontiers with disease-specific relevance. Collectively, this review repositions CDKs as cell cycle regulators and central signaling integrators within complex disease networks. We propose a structural and mechanistic framework to guide the rational targeting of CDKs in the precision medicine era, paving the way for the next generation of kinase-based therapeutics.\n\nID: 42435831\nTitle: Evaluation of the impact of gamma-aminobutyric acid on diabetic retinopathy in a large US population-based cohort.\nAbstract: To investigate how exposure to GABAergic medications affects diabetic retinopathy (DR) development, progression, and complications. Retrospective clinical cohort study using multi-institutional electronic health record data (TriNetX, US Collaborative Network) PARTICIPANTS: : Adults aged \u226518 years with type 2 diabetes mellitus with ophthalmology follow-up. Study cohorts had GABAergic prescription records for 6-months, 1-year, 3-years, or 5-years; control cohorts had no GABAergic prescriptions ever. Cohorts were propensity-score matched (PSM) on demographics, systemic comorbidities, common indications for GABAergic medications, and ophthalmic confounders. Outcomes included incident DR, progression from mild/moderate nonproliferative DR to severe nonproliferative DR, proliferative DR, or interventions required in advanced DR, and incident DR complications. Hazard ratio (HR) and 95% confidence intervals (CI); significance threshold <0.9 or >1.1. After successful PSM, there were 110,495 (6-months), 99,187 (1-year), 63,194 (3-years), and 40,810 (5-years) DR-naive study patients with the respective GABAergic prescription durations of interest. Compared to 109,603 DR-naive control patients, study patients demonstrated a significantly reduced HR for DR development at all time points from 6-months (HR 0.61, 95% CI 0.57-0.65) to 5-years (HR 0.81, 95% CI 0.77-0.85). Study patients (n=14,644) with baseline mild/moderate nonproliferative DR had a significantly reduced hazard of progressing to severe nonproliferative DR, proliferative DR, or DR interventions with 6-months (HR 0.75, 95% CI 0.68-0.82) and 1-year (HR 0.69, 95% CI 0.73, 0.86) GABAergic exposure. Prescription for 6-months (HR 0.74, 95% CI 0.68-0.80) to 3-years (HR 0.80, 95% CI 0.84-0.86) was associated with a significantly reduced hazard for DR complications. Stratification by 4 specific medication indications consistently showed a reduced hazard for DR development with a 6-month prescription duration. GABAergic medication use, particularly short-term exposure, is associated with a reduced hazard of DR development, progression, and complications. These exploratory findings support a potential role of GABAergic modulation in diabetic retinal disease.\n\nID: 42435764\nTitle: Neuron-Targeted Exosomal Delivery of siRNA Against RIPK3 Slows Neurodegenerative Progression in Alzheimer's Disease.\nAbstract: A major challenge in RNA therapeutics for central nervous system disorders is the lack of delivery systems capable of crossing the blood-brain barrier (BBB) while achieving cell-type-specific targeting. Herein, we develop an engineered exosomal siRNA delivery platform for systemic, neuron-targeted RNA transport to the brain. The platform leverages exosomes derived from an immortalized mouse hippocampal neuronal cell line as a biomimetic and functionally privileged material source, enhancing neuronal uptake and intracellular delivery efficiency. Through surface functionalization with a rabies virus glycoprotein-derived peptide, the system enables receptor-mediated BBB transcytosis and programmable siRNA loading. In human cortical organoids, the platform achieves efficient cytosolic delivery and robust gene silencing in neurons, demonstrating high delivery precision and bioavailability. As a proof of concept, targeting receptor-interacting protein kinase 3 (RIPK3) modulates necroptosis, a key pathway in inflammatory neurodegeneration. In transgenic mouse models, systemic administration suppresses RIPK3/MLKL signaling, reduces neuronal loss, and alleviates neuroinflammation and tau-associated pathology. Transcriptomic analyses further indicate stabilization of neuronal homeostasis across vulnerable brain regions. Collectively, the study establishes a modular and programmable exosomal RNA delivery platform and highlights age-defined, cell-derived biomaterials as a generalizable strategy for overcoming delivery barriers in neurological diseases.\n\nID: 42435652\nTitle: Melatonin reprograms antioxidant defenses to suppress ferroptosis via Homer1a/mGluR1-Nrf2/xCT signaling after retinal ischemia-reperfusion.\nAbstract: Melatonin (Mel) exerts antioxidant and anti-ferroptosis effects not only via the canonical receptors Mt1/Mt2 but also via metabotropic glutamate receptor 1 (mGluR1)/glutamate-mediated signaling. Nevertheless, the regulatory mechanism by which Mel modulates mGluR1/glutamate signaling in retinal ischemia-reperfusion (I/R) injury and its downstream effects on ferroptosis and oxidative stress remain poorly understood. Here, bulk RNA sequencing identified that the Mel receptors Mt1/Mt2 and ferroptosis/iron-redox regulators (Gpx4, Fth1, and xCT) were significantly downregulated after retinal I/R. Mel improved retinal structural and visual function, visual-guidance behavior, and electrophysiological responses following I/R while concurrently reducing ferroptotic and inflammatory injury markers. These benefits were largely abolished by Mel membrane receptor antagonists. Mechanistically, Mel upregulated Homer1a in vivo and in vitro in a receptor-dependent manner. Conditional deletion of Homer1a in transgenic mice, as well as Homer1a knockdown in retinal ganglion cells (RGCs), abolished the protective effects of Mel on visual function, along with its anti-ferroptotic and anti-inflammatory activities. Molecular docking and immunoprecipitation assays demonstrated that Mel restored the interaction between Homer1a and mGluR1 and activated the xCT/GSH/Gpx4 antioxidant axis. Pharmacologic inhibition of xCT with the buthionine sulfoximine (BSO) simulation pr genetic interference with xCT expression counteracted the protective effects of Mel. Mel also enhanced Nrf2-mediated transcriptional expression of cCT in a Homer1a/mGluR1-dependent manner. Collectively, our results define a Mel-Homer1a/mGluR1-Nrf2/xCT signaling cascade that promotes RGCs survival after I/R by suppressing ferroptosis/iron-redox reactions, thereby providing a potential translatable strategy for receptor-targeted intervention in I/R-related retinal damage.\n\nID: 42435146\nTitle: Bisphenol S-Induced Neurobehavioral Impairment Is Characterized by c-Jun Activation and Distinct Dysregulation of Nrf2 and BDNF in the Zebrafish Brain.\nAbstract: Bisphenol S (BPS), a widely used substitute for bisphenol A (BPA), is increasingly detected in consumer products and aquatic environments, yet its neurotoxic potential remains insufficiently understood. Building on our previous findings that BPS induces anxiety-like behaviour and oxidative damage in zebrafish, the present study investigates the mechanistic basis of BPS-mediated neurotoxicity with a focus on stress-activated kinase signalling, antioxidant defences, and neurotrophic regulation. Adult zebrafish were exposed to a sub-lethal concentration of BPS (63.93 \u00b5M) for 7, 14, and 21 days, followed by neurobehavioral, biochemical, molecular, and histological analyses. Chronic BPS exposure resulted in pronounced anxiety-like behaviour and deficits in recognition memory, as evidenced by performance impairments in the novel tank diving test and novel object recognition test. These behavioural alterations coincided with elevated oxidative stress, including increased lipid peroxidation and protein carbonylation, alongside a progressive decline in superoxide dismutase activity. BPS also caused a significant, time-dependent rise in intracellular calcium levels, suggesting disrupted cellular homeostasis. Neuromorphological assessment revealed marked neuronal loss and pyknosis in the periventricular grey zone of the optic tectum, consistent with oxidative and excitotoxic damage. At the molecular level, western blot analysis showed robust activation of the c-Jun N-terminal kinase (JNK) pathway, evidenced by elevated phosphorylated c-Jun, accompanied by a substantial reduction in Nrf2 expression, indicating suppressed antioxidant defence capacity. In parallel, expression of brain-derived neurotrophic factor (BDNF) was significantly decreased following prolonged exposure, pointing to impaired neurotrophic support and synaptic plasticity. Together, these findings demonstrate that BPS induces neurobehavioral disturbances through a multifaceted mechanism involving oxidative stress, calcium dysregulation, activation of pro-apoptotic JNK signalling, suppression of Nrf2-mediated antioxidant activity, and inhibition of BDNF expression.\n\nID: 42432341\nTitle: Microglial synaptic pruning in early Alzheimer's disease: emerging roles of the IL-1\u03b2-NLRP3 axis.\nAbstract: Alzheimer's disease is a progressive neurodegenerative disorder characterized by early synaptic dysfunction that precedes overt neuronal loss and cognitive decline. While amyloid-\u03b2 and tau pathologies have long dominated disease models, growing evidence highlights neuroinflammation as a critical driver of early pathological changes. In particular, microglia-mediated inflammatory signaling has emerged as a key regulator of synaptic integrity. This review focuses on the interleukin-1\u03b2 (IL-1\u03b2)-NLRP3 inflammasome axis as a central mechanism linking innate immune activation to aberrant synaptic pruning in early Alzheimer's disease. Activation of the NLRP3 inflammasome in microglia by amyloid-\u03b2 and related danger signals leads to caspase-1-dependent maturation and release of IL-1\u03b2. Elevated IL-1\u03b2 amplifies inflammatory signaling, alters microglial phenotype, and promotes complement-mediated tagging of synapses, resulting in excessive elimination of functional synaptic connections. Experimental evidence from in vitro systems, transgenic mouse models, and pharmacological inhibition studies supports a causal role for this axis in synapse loss, impaired synaptic plasticity, and cognitive deficits. Importantly, these inflammatory and synaptic alterations occur at early disease stages, underscoring their relevance to disease initiation rather than late-stage neurodegeneration. The review further discusses the impact of IL-1\u03b2-NLRP3 signaling on neuronal network function, hippocampal plasticity, and cognitive performance, as well as its translational implications. Therapeutic strategies targeting inflammasome activation or IL-1\u03b2 signaling show promise in preserving synaptic function in preclinical models. Overall, the IL-1\u03b2-NLRP3-synapse axis represents a compelling framework for understanding early Alzheimer's disease pathology and offers a rational target for early intervention strategies to slow disease progression.\n\nID: 42432163\nTitle: Glucagon-like peptide-1 agonists in Parkinson's disease: a meta-analysis.\nAbstract: Type 2 diabetes and Parkinson's disease (PD) share underlying pathways, including insulin resistance and neuroinflammation. While glucagon-like peptide-1 receptor agonists (GLP-1 RAs) show neuroprotective promise in preclinical models, clinical trials have produced conflicting results. This meta-analysis systematically evaluates the efficacy and safety of GLP-1 RAs in PD, specifically distinguishing between symptomatic relief and potential disease modification. We searched PubMed, Scopus, Web of Science, Cochrane Library, and Embase through November 2025 for randomized, double-blind, placebo-controlled trials of GLP-1 RAs in idiopathic PD. The primary motor outcome, the Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III (motor examination), was analyzed using a random-effects model and strictly stratified by \"ON\" versus \"OFF\" medication states. We included four high-quality trials comprising 667 patients. GLP-1 RAs failed to significantly improve motor function in either the OFF-medication state (mean difference [MD]\u2009-\u20090.69; 95% confidence interval [CI]\u2009-\u20092.81 to 1.43; p\u2009=\u20090.52) or ON-medication state (MD\u2009-\u20090.86; 95% CI\u2009-\u20093.35 to 1.63; p\u2009=\u20090.50). Furthermore, no meaningful benefits emerged for non-motor symptoms, cognition, or quality of life. Conversely, treatment significantly increased gastrointestinal adverse events, including nausea (risk ratio [RR]\u2009=\u20092.48), vomiting (RR\u2009=\u20094.53), and clinically concerning weight loss (RR\u2009=\u20093.32). Synthesizing the latest phase 3 data, current GLP-1 RAs offer neither disease-modifying nor symptomatic motor benefits for the broader PD population. Given the pronounced risk of weight loss, their routine use is unwarranted. Future trials must shift focus toward biologically enriched subgroups or newer-generation incretin analogs.\n\nID: 42427742\nTitle: Selective knockout of PKA regulatory subunits reveal opposite catalytic and metabolic consequences with implications for Alzheimer's disease.\nAbstract: cAMP-dependent Protein Kinase A (PKA) is a master regulator of cell signaling involved in energy metabolism, synaptic plasticity, and stress response. Dysregulated PKA signaling is implicated in diseases including neurodegeneration and cancer. PKA catalytic activity is regulated by two nonredundant regulatory subunits, Type I (RI\u03b1/RI\u03b2) and Type II (RII\u03b1/RII\u03b2), whose divergent functions are not fully understood. We generated double-knockout (KO) cell lines of RI\u03b1/RI\u03b2 and RII\u03b1/RII\u03b2 subunits and performed multiplexed MS-based proteomic and phosphoproteomic profiling under basal and glucose-perturbed conditions. We found that RI and RII loss drives distinct, and often opposite, remodeling of the cellular proteome and phosphoproteome. While both mutants blunted metabolic flexibility to glycolytic stressors and stimuli, RI and RII KO cells exhibited elevated and depressed glycolytic signaling, respectively. Interestingly, RI KO increased the abundance and kinase activity of the PKA catalytic subunit C\u03b1 isoform, leading to an increase in PKA substrate phosphorylation, whereas RII KO decreased the abundance, kinase activity, and substrate phosphorylation by the catalytic subunit C\u03b2 isoform. Notably, one of the most differentially affected PKA sites between RI and RII KOs maps to Tau, whose hyperphosphorylation is a hallmark of Alzheimer's disease. Loss of RI increased Tau phosphorylation, which was not only caused by increased PKA catalytic activity, but also a higher binding affinity of Tau to RII subunits on the negatively-charged flexible linker region. Overall, the present study demonstrates that PKA RI and RII subunits play nonredundant roles in modulating PKA activity, metabolic flexibility, and phospho-regulation of key disease-associated substrates such as Tau.\n\nID: 42426288\nTitle: The emerging role of circular RNAs in neurodegenerative diseases and viral infections.\nAbstract: Circular RNAs (circRNAs) represent a class of highly stable, covalently closed RNA molecules increasingly recognized as important regulators of brain aging and neurodegenerative disease. Growing evidence also implies circRNAs in viral infection, suggesting a potential intersection between viral neuropathogenesis and neurodegeneration. However, no studies have yet directly integrated circRNAs, neurotropic viral infections, and neurodegenerative disorders within a single mechanistic framework. To date, specific circRNAs have been linked to the progression of Alzheimer's disease and Parkinson's disease, where they regulate central pathological processes including amyloid-\u03b2 clearance, neuroinflammation, synaptic plasticity, neuronal apoptosis, and oxidative stress. Moreover, it has been established that both host cells and viruses produce circRNAs during infection. Virus-derived circRNAs can enhance viral replication, promote immune evasion, and support latency. In contrast, host circRNAs contribute to antiviral defense by acting as microRNA sponges, interacting with viral proteins, or encoding peptides with antiviral activity, mechanisms particularly explored in viral oncogenesis. In this review, we will evaluate the most updated research evidence on the role of circRNAs in major neurodegenerative diseases and neurotropic viral infections. Considering the growing concern regarding the long-term neurological consequences of viral infections, including chronic neuroinflammation, viral reactivation, and post-viral syndromes, dysregulated circRNAs may represent a mechanistic link between viral infection and associated neurodegenerative processes. Finally, we will discuss future directions for identifying circRNAs-based biomarkers and developing circRNAs-targeted therapeutic strategies for age-related and virus-associated neurological disorders.\n\nID: 42446728\nTitle: Protein kinases as therapeutic targets in Alzheimer's disease: challenges, insights, and new frontiers.\nAbstract: Alzheimer's disease (AD) remains the leading cause of dementia worldwide, imposing an enormous and growing societal burden with more than 55 million people affected globally. Despite decades of intensive investigation, existing therapeutic options provide only modest symptomatic relief and fail to prevent or slow disease progression, emphasizing the critical need for interventions that target the fundamental molecular mechanisms of neurodegeneration. Pathologically, Alzheimer's disease is characterized by extracellular accumulation of amyloid-\u03b2 plaques, intracellular neurofibrillary tangles formed by hyperphosphorylated tau, profound synaptic loss, chronic neuroinflammation, and extensive neuronal degeneration. Although amyloid-focused strategies have long dominated drug development, their limited clinical benefit and safety liabilities highlight the multifactorial nature of AD and the need to move beyond amyloid-centric paradigms. Protein kinases have emerged as key integrators of multiple pathogenic processes in AD, governing tau phosphorylation, amyloid precursor protein processing, synaptic signaling, and neuroimmune responses. Aberrant kinase signaling drives tau pathology and propagation, promotes amyloidogenic pathways, disrupts synaptic function, and perpetuates inflammatory cascades. While extensive work on kinases such as GSK-3\u03b2, CDK5, JNKs, and CSF1R has firmly established the relevance of kinase dysregulation in AD, no kinase-directed therapy has yet translated into clinical success. This review highlights emerging kinase targets beyond these classical pathways, including Fyn, Casein Kinase 1 Delta (CK1\u03b4), Tau-Tubulin Kinase 1 (TTBK1), and Dual Leucine Zipper Kinase (DLK), which are supported by mechanistic insights and compelling preclinical evidence. Continued advances in brain-penetrant, isoform-selective, and mechanism-driven kinase inhibitor design may enable the development of next-generation disease-modifying therapies for Alzheimer's disease.\n\nID: 42442404\nTitle: Cytomegalovirus-induced T cell responses accelerate Alzheimer's disease progression in mice.\nAbstract: Infections have long been implicated as causative factors in Alzheimer's disease (AD). Multiple studies have further suggested a key role for herpesviruses, such as cytomegalovirus (CMV). Using transgenic 3xTg-AD mice, we demonstrate that systemic infection with the \u03b2-herpesvirus murine CMV (MCMV) accelerates the development of cognitive decline, tauopathy and synaptic loss in the hippocampus, all of which are key features of AD. Accelerated disease progression after infection was associated with substantial lymphocyte infiltration into the brain, dominated by MCMV-specific effector memory CD8+ T cells expressing CXCR3. T cell receptor analyses revealed that clonally diverse virus-specific CD8+ T cells were selectively recruited into the brain during the development of AD. T cell depletion or treatment with the antiviral drug valganciclovir during chronic infection reduced lymphocytic infiltrates in the brain and reversed cognitive decline. These data provide a mechanistic link between chronic viral infections and the development of AD.\n\nID: 42439604\nTitle: Neurodegeneration in Glaucoma: Microstructural Magnetic Resonance Imaging Evidence Within and Beyond the Visual Pathway.\nAbstract: To investigate structural and microstructural brain changes in glaucoma using multimodal magnetic resonance imaging across primary, secondary, and higher-order visual brain regions, and their associations with glaucoma diagnosis, optical coherence tomography-derived retinal nerve fiber layer (RNFL) thickness, ganglion cell layer (GCL) thickness, and/or IOP. From the UK Biobank, we identified glaucoma cases (n = 1465) and 10-fold age- and sex-matched controls (n = 14,650). Magnetic resonance imaging modalities comprised T1-weighted structural, diffusion tensor imaging, and neurite orientation dispersion and density imaging. Associations with glaucoma status and ophthalmic measures (RNFL, GCL, and IOP) were assessed using regression models adjusted for age, sex, polygenic risk score, and Townsend Deprivation Index, with false discovery rate correction. Glaucoma was associated with reduced gray matter volume in primary visual regions (lateral geniculate nucleus, optic chiasm, intracalcarine cortex, and occipital pole) and diffusion tensor imaging/neurite orientation dispersion and density imaging abnormalities in the posterior thalamic radiation (all P < 0.001). Glaucoma was also associated with secondary regions (lateral occipital cortex, lingual gyrus, and occipital fusiform gyrus) and microstructural changes in the inferior fronto-occipital and inferior longitudinal fasciculus (all P < 0.001). Higher-order and supporting regions were also associated with glaucoma, including the right putamen and paracingulate gyrus (P < 0.05). The RNFL (P < 0.05) and GCL (P < 0.01) correlated linearly with most primary visual regions, whereas the IOP showed no significant associations. Glaucoma is associated with structural and microstructural brain changes beyond the eye to primary, secondary, and higher-order brain regions. These changes correlate with RNFL and GCL thinning but not IOP. Involvement of the occipital pole is consistent with the plausibility of trans-synaptic degeneration in glaucoma.\n\nID: 42431902\nTitle: Molecularly defined auditory neuron subtypes show different vulnerabilities to noise- and age-related synaptopathy in mice.\nAbstract: Neuronal subtype-specific synaptopathy is a hallmark of many forms of neurodegeneration. We examined the cellular basis for synaptic vulnerability in the auditory system, where three subtypes of spiral ganglion neurons (SGNs)-Ia, Ib, and Ic-carry acoustic information from the cochlea to the brain. In response to noise and aging, a subset of synapses between inner hair cells and SGNs are lost, but it is unclear how this loss varies across SGN subtypes. Using genetic labeling, we showed that Ia SGNs have larger post-synaptic densities (PSDs) than Ib and Ic SGNs and are the most resilient subtype. Ia PSD volumes increase with age and are unchanged after noise exposure. By contrast, average Ib/Ic PSD volumes do not change with age but decrease with noise. Genetic reprogramming of Ib/Ic neurons to a Ia-like identity provides significant protection against noise-induced synaptopathy, linking identity to resilience and providing an entry point for therapeutics.\n\nID: 42414763\nTitle: Atraric acid enhances neuronal survival and cognition against D-galactose-induced neurodegeneration via BDNF/TrkB/AKT signaling.\nAbstract: Aging-induced neurodegeneration is characterized by cognitive impairment, elevated oxidative stress, neuroinflammation, synaptic loss, and neuronal death. Atraric acid (AA), a phenolic compound obtained from lichens, is reported to have potent anti-inflammatory and antioxidant effects in various disease models. However, aging-induced cognitive impairment and dementia are still not elucidated. To fill this gap, we investigated AA (20\u00a0mg/kg/day, intraperitoneally (i.p.) for 4\u00a0weeks) against D-galactose (D-gal) (120\u00a0mg/kg/day, i.p. for 8\u00a0weeks)-induced brain senescence and memory dysfunction in mice. Behavioral tests, including NOR, MWM, and Y-maze, were conducted to assess cognitive function, followed by biochemical and immunofluorescence analyses. AA restored the BDNF/TrkB/Akt signaling axis disrupted by D-gal administration. Furthermore, immunoblotting for Nrf-2 and HO-1 revealed elevated expression in the mouse cortex and hippocampus. AA also enhanced antioxidant enzymes, including glutathione (GSH), glutathione S-transferase (GST), catalase (CAT), and superoxide dismutase (SOD), while reducing lipid peroxidation (LPO), thereby supporting its antioxidant role. Moreover, D-gal enhanced NF-kB-mediated neuroinflammation, apoptotic markers including caspase-3 and PARP-1, and suppressed synaptic proteins (SNAP-23 and PSD-95). Interestingly, these expression aberrations were reversed upon AA administration. Histological analyses using Nissl and Fluoro-Jade B staining further supported neuronal protection in the cortex and hippocampus. Collectively, these findings suggest that AA exerts neuroprotective effects against D-gal-induced aging and cognitive decline by reducing oxidative stress, neuroinflammation, neuronal apoptosis, and enhancing synaptic plasticity through BDNF/TrkB/Akt/CREB signaling.\n\nID: 42409182\nTitle: Microglial PTP1B promotes synaptic pathology and cognitive deficits in chronic Toxoplasma gondii infection.\nAbstract: Chronic infection with the neurotropic pathogen Toxoplasma gondii has been epidemiologically associated with a risk of neurodegeneration; however, the mechanisms driving infection-associated cognitive decline remain unclear. We investigated the role of microglial protein-tyrosine phosphatase 1B (PTP1B) as a potential driver of neuropathology in chronic toxoplasmosis. Using a murine model, we demonstrate that PTP1B expression is elevated in the hippocampus following infection. Global genetic ablation or pharmacological inhibition of PTP1B rescued infection-induced cognitive deficits and mitigated neuroinflammation. Crucially, microglia-specific deletion of Ptp1b prevented synaptic loss and cognitive impairment. Mechanistically, we show that microglial PTP1B potentiates the nuclear factor-kappa B (NF-\u03baB) pathway, promoting complement component 1q (C1q)-mediated synaptic tagging and subsequent neuronal structural damage. Validating the clinical relevance of these findings, we observed significantly elevated PTP1B levels in peripheral blood mononuclear cells from T. gondii-seropositive individuals, which correlated with inflammatory markers. Overall, our findings identify microglial PTP1B as a pivotal mediator of T. gondii-associated neurodegeneration.\n\nID: 42400155\nTitle: Tau protein differentially affects Piezo1 and Kir2.1 channels in brain capillary endothelial cells.\nAbstract: Accumulation of amyloid-\u03b2 (A\u03b2) peptides and Tau proteins in the brain is a hallmark of neurodegeneration. Such build-up forms A\u03b2 plaques and Tau neurofibrillary tangles, both of which are associated with synaptic loss, cognitive decline, and reduced cerebral blood flow in Alzheimer's disease (AD). Two ion channels in brain capillary endothelial cells (ECs)-the inwardly rectifying potassium channel Kir2.1 and the mechanosensitive channel Piezo1-are critical regulators of cerebral blood flow, and both display impaired activity in AD. Whether A\u03b2 and Tau affect these channels remains incompletely understood. Using patch-clamp electrophysiology and freshly isolated mouse brain capillary ECs, we examined whether A\u03b21-40 or Tau-441 directly modulate Kir2.1 or Piezo1 function. Exogenously applied A\u03b21-40 (10-100 nM) and Tau-441 (10-50 nM) had minimal effect on Kir2.1 current density, indicating that the Kir2.1 deficits observed in AD are less likely caused by direct interactions with A\u03b2 or Tau. In contrast, we previously demonstrated that nanomolar A\u03b21-40 enhanced Piezo1 function. We further show here that 50 nM Tau-441 significantly increased Piezo1 open probability, and this enhancement was abolished by the superoxide dismutase and catalase mimetic EUK-134. These data collectively suggest that altered Piezo1 function in neurodegenerative disease could involve a direct effect of A\u03b2 peptides or Tau proteins and further suggest that acute exposure to these proteins minimally impacts Kir2.1 activity. These novel findings present a new pathway through which Tau proteins could impair neurovascular function during neurodegeneration.\n\nID: 42366666\nTitle: [Non-glaucomatous optic nerve atrophy: epidemiology, etiological structure, and clinical diagnostic features].\nAbstract: Non-glaucomatous optic nerve atrophy (ONA) is a polyetiological pathological condition characterized by the loss of retinal ganglion cell axons and structural changes in the optic nerve head.

Elevated intraocular pressure (IOP) is a major risk factor for glaucoma; however, it is neither necessary nor sufficient for glaucomatous neurodegeneration, as patients can exhibit high IOP without developing glaucoma and patients can develop glaucoma with normal IOP. Yet FDA-approved treatment options are largely limited to approaches to minimize risk and reduce IOP. Thus, there is a critical need to target other aspects of glaucoma pathophysiology. Neuroinflammation is broadly defined here as immune-relevant responses, often involving microglia and astrocytes, within the central nervous system which may include peripheral immune cell infiltration. Burgeoning evidence has implicated glia in the development and progression of glaucoma in human tissues and mouse models. Most mouse models of glaucoma to date have shown that microglia and astrocytes are reactive in early stages of glaucomatous neurodegeneration prior to overt RGC loss. However, there is growing evidence that human and mouse glia adopt distinct phenotypes in response to neurodegeneration. Thus, there is critical need to expand our studies to include the new generations of human cell culture models. In this review, we discuss: 1) the evidence of neuroinflammatory processes in human glaucoma; 2) models of glaucoma relevant neuroinflammation; and the evidence specifically for 3) innate immune cell-driven and 4) macroglia-driven processes.\n\nID: 42359047\nTitle: Directing Neutrophil Fate via Sensory-Immune Interactions Accelerates Diabetic Bone Healing.\nAbstract: The intractability of diabetic bone defects mainly results from derailed inflammation. While peripheral neuropathy is a common comorbidity, whether sensory dysfunction contributes to uncontrolled inflammation in diabetes is poorly understood. Here, within diabetic bone defects, we show that diminished sensory innervation is coupled with disrupted immune dynamics, characterized by both delayed neutrophil chemotaxis and abnormal neutrophil retention that resulted from impaired macrophage efferocytosis. Therefore, we design a chocolate chip cookie-like scaffold, in which the surface-embedded microspheres function as \"chips\" enabling burst interleukin-8 (IL-8) release, while the surrounding matrix provides sustained nerve growth factor release from silk fibroin matrix. Timely neutrophil chemotaxis induced by IL-8 triggers bone healing via stem cell recruitment, which is reinforced by sensory innervation by inducing neutrophil N2 polarization. Notably, macrophages preferentially established intimate physical proximity to outgrowing neurites to form a synapse-like structure, where they restore efferocytosis driven by neuronal Galectin-3. Moreover, spatiotemporally regulating neuroimmune circuit enhances mandibular bone regeneration in diabetic rats, highlighting the therapeutic potential of neuroimmune interaction in programming diabetic inflammation resolution.\n\nID: 42352232\nTitle: Calcium at the Helm: Mechanisms and Therapeutic Targets in the Retinal Neurovascular Unit.\nAbstract: Retinal neurovascular unit (RNVU) dysfunction underlies major blinding and neurodegenerative conditions including glaucoma, diabetic retinopathy (DR), age-related macular degeneration (AMD), retinal ischemia-reperfusion (RIR) injury, and Alzheimer's disease (AD)-associated retinopathy. Within the RNVU, calcium ions coordinate neurotransmission, glial activation, vascular tone, and blood-retinal barrier maintenance, and calcium dysregulation is emerging as a unifying pathogenic hub across these conditions. Although upstream triggers differ, including mechanical stress in glaucoma, hyperglycemia in DR, oxidative damage in AMD, ischemic energy failure in RIR, and amyloid-\u03b2-driven endoplasmic reticulum stress in AD, all converge on disruption of intracellular calcium homeostasis, producing shared downstream consequences including excitotoxic injury of retinal ganglion cells (RGCs), M\u00fcller cell reactive gliosis, and pericyte hypercontraction. Broad-spectrum calcium channel blockade has shown limited clinical success, underscoring the need for cell-type-specific and pathway-selective approaches. This review therefore catalogs key interventional nodes, including transient receptor potential (TRP) channel antagonists, T-type calcium channel inhibitors, calcium/calmodulin-dependent protein kinase II (CaMKII) suppressors, and mitochondrial permeability transition pore (mPTP) inhibitors, and discusses how precision targeting of these pathways may restore RNVU homeostasis and open a therapeutic window into central nervous system (CNS) degenerative disorders.\n\nID: 42352057\nTitle: Oxidative Stress in Glaucoma: From Pathogenic Mechanisms to Emerging Antioxidant Therapies.\nAbstract: Glaucoma is the leading cause of irreversible blindness worldwide and is characterized by progressive retinal ganglion cell (RGC) loss and optic nerve degeneration. While elevated intraocular pressure (IOP) remains the primary modifiable risk factor, a certain proportion of patients continue to deteriorate despite adequate IOP control, pointing to IOP-independent mechanisms of neurodegeneration. Oxidative stress-defined as an imbalance between the production of reactive oxygen species and the capacity of endogenous antioxidant defenses-has emerged as a central, multi-tiered contributor to glaucoma pathogenesis. In the anterior segment, chronic oxidative damage to the trabecular meshwork impairs aqueous humor outflow and drives IOP elevation. In addition, oxidative stress may impair ocular biomechanical integrity, including corneal hysteresis and lamina cribrosa, resulting in heightened susceptibility to IOP fluctuations. In the posterior segment, oxidative stress directly contributes to mitochondrial damage and vascular endothelial injury, leading to RGC apoptosis. The nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein 1 (Keap1) pathway coordinates the principal endogenous antioxidant response, while nicotinamide adenine dinucleotide (NAD+) depletion links redox imbalance to metabolic vulnerability of RGCs. This narrative review synthesizes evidence published up to March 2026 on the molecular mechanisms of oxidative stress in glaucoma, the role of biomarkers in aqueous humor and systemic circulation, and the translational landscape of antioxidant-based neuroprotection-including nicotinamide, coenzyme Q10, alpha-lipoic acid, and Nrf2-activating compounds. We highlight gaps between preclinical promise and clinical evidence, and outline priorities for future randomized controlled trials.\n\nID: 42351640\nTitle: Glaucoma and Autoimmunity: Immunopathogenic Mechanisms and Emerging Immunomodulatory Therapies.\nAbstract: Glaucoma is a chronic progressive optic neuropathy and one of the leading causes of irreversible blindness worldwide. Although elevated intraocular pressure remains the most important modifiable risk factor, increasing evidence suggests that immune dysregulation and autoimmune responses also contribute substantially to disease onset and progression. Clinical studies across different glaucoma subtypes have identified subtype-dependent immune abnormalities, including altered serum autoantibody profiles, dysregulated cytokine and chemokine expression, and changes in peripheral immune cell subsets. Experimental and translational studies further indicate that multiple immunopathogenic mechanisms are involved in glaucomatous neurodegeneration, including glial cell-mediated immune responses, activation of pattern recognition receptor signalling pathways, adaptive immune responses, and complement cascade dysregulation. These processes may interact to sustain chronic neuroinflammation, promote retinal ganglion cell injury, and accelerate optic nerve degeneration. Importantly, a better understanding of immune involvement in glaucoma has generated growing interest in immunomodulatory therapy as a potential strategy beyond intraocular pressure lowering. Targeting microglial activation, inflammatory signalling pathways, adaptive immune imbalance, and complement-mediated injury has shown neuroprotective potential in animal or in vitro models, whereas clinical evidence in glaucoma patients remains limited. These findings may provide preliminary directions for future therapeutic development. In this review, we summarise the current clinical evidence linking glaucoma with autoimmunity, discuss the major immune mechanisms implicated in disease pathogenesis, and highlight recent advances in immunomodulatory therapeutic strategies. Elucidating the immune basis of glaucoma may help pave the way for more precise and effective treatments for this complex optic neuropathy. We believe that immune dysregulation in glaucoma functions as a context-dependent amplifier of retinal ganglion cell injury rather than a uniform primary driver, with innate (microglia/astrocytes), adaptive (T/B cells, HSP-specific immunity), and complement pathways interacting to sustain neuroinflammation and neurodegeneration. This integrated immune response contributes to subtype- and stage-specific vulnerability, and targeting these maladaptive immune mechanisms represents a promising, precision-guided strategy for neuroprotection beyond intraocular pressure lowering.\n\nID: 42346137\nTitle: Neuroinflammation in Alzheimer's Disease (AD) and Glioblastoma (GBM): Shared Mechanisms and Therapeutic Insights.\nAbstract: Neuroinflammation is a key feature of both Alzheimer's disease (AD) and glioblastoma, although it leads to different outcomes in each disorder. In AD, chronic activation of microglia and astrocytes by amyloid-\u03b2 and tau contributes to neuronal injury and cognitive decline. In glioblastoma, tumor cells exploit inflammatory pathways to create an immunosuppressive microenvironment that supports tumor growth. This review compares the shared and distinct neuroinflammatory mechanisms in AD and glioblastoma and highlights their therapeutic relevance. This study was conducted as a narrative review based on a PubMed search performed by three reviewers. English-language articles on AD, glioblastoma, and neuroinflammatory pathways were included, covering original studies, reviews, meta-analyses, and experimental and clinical reports. Keywords included neuroinflammation, microglia, astrocytes, tumor-associated macrophages, inflammasomes, NLRP3, NF-\u03baB, HIF-1\u03b1, cytokines, blood-brain barrier, and miRNAs. Due to study heterogeneity, findings were synthesized descriptively. AD and glioblastoma share major neuroinflammatory mechanisms, including microglial and astrocytic activation, cytokine signaling, inflammasome activity, blood-brain barrier dysfunction, hypoxia-related changes, and miRNA regulation. In AD, these pathways promote chronic inflammation, synaptic loss, and neurodegeneration, with NLRP3, NF-\u03baB, and M1-like microglial polarization playing central roles. In glioblastoma, similar pathways are redirected toward tumor progression through tumor-associated macrophages, reactive astrocytes, angiogenesis, immune evasion, and therapy resistance. Key overlapping mediators include IL-1\u03b2, TNF-\u03b1, NF-\u03baB, HIF-1\u03b1, GSK-3\u03b2, and selected miRNAs. AD and glioblastoma are connected by common neuroinflammatory pathways, but these processes result in neurodegeneration in AD and tumor support in glioblastoma. Understanding these shared and divergent mechanisms may guide the development of biomarkers and targeted therapies focused on microglia, inflammasomes, cytokines, and immune reprogramming in both diseases.\n\nID: 42345413\nTitle: Impaired Dynamic Postural Control in People with Diabetes: An Exploratory Cross-Sectional Study Using Computerized Dynamic Posturography (Bertec).\nAbstract: This study assessed static and dynamic postural control in individuals with type 1 (T1D) and type 2 diabetes (T2D) using Computerized Dynamic Posturography (Bertec), hypothesizing that diabetes, especially with diabetic peripheral neuropathy (DPN), leads to significant impairments in postural stability. A total of 94 participants with diabetes (T1D: n=49, T2D: n=45) and 94 age- and sex-matched controls underwent postural assessments using the Sensory Organization Test (SOT) and Motor Control Test (MCT). The SOT evaluated sensory system contributions (somatosensory,visual, vestibular), while the MCT assessed postural recovery responses. Both T1D and T2D groups exhibited impaired SOT performance compared to controls (P < .05). Type 1 diabetes showed impaired visual function (P < .05), while both groups demonstrated poorer postural stability in conditions requiring vestibular input (P < .05) and slower MCT response times (10 of 14 abnormal, P < .05). T2D participants relied excessively on visual input (preference function: P < .05). No significant associations were detected between DPN, body mass index, Hemoglobin A1c (HbA1c), or diabetes duration with postural control impairments. Diabetes impairs postural control, particularly in conditions that rely heavily on vestibular and visual inputs, regardless of DPN. Advanced tools like Bertec reveal real-world deficits, highlighting the potential value of these findings in informing future fall-prevention strategies for individuals with diabetes.\n\nID: 42332767\nTitle: HDAC7 acts as an astrocytic mediator of A\u03b2 pathology that directly engages IKK to drive astrocyte neurotoxicity and neurodegeneration in Alzheimer's disease.\nAbstract: Astrocytes undergo reactive transformations in response to pathological stimuli and play a critical role in neuronal loss associated with Alzheimer's disease (AD). However, the intrinsic mechanisms through which astrocytes detect amyloid-\u03b2 (A\u03b2) pathology and develop neurotoxic properties remain inadequately understood. The dysregulation of class IIa Histone deacetylases (HDACs) has been implicated in astrocyte dysfunction under pathological conditions. This study aims to elucidate the role of HDAC7 as an astrocytic mediator of A\u03b2 that drives the formation of neurotoxic reactive astrocytes, and to propose HDAC7 as a potential therapeutic target for mitigating neuronal loss and cognitive deficits in AD. We examined HDAC7 expression in APP/PS1 mice of varying ages using RT-qPCR, Western blotting, and immunostaining analysis. Astrocyte-specific HDAC7 overexpression and knockdown were achieved\u00a0through adeno-associated virus (AAV) delivery (GfaABC1D promoter) in wild-type (WT) and APP/PS1 mice, followed by behavioral tests, immunostaining, RT-qPCR, and RNA-seq. Mechanistic studies were conducted using primary astrocytes derived from WT and\u00a0Hdac7flx/flx\u00a0mice, employing co-immunoprecipitation, Western blotting, and neuron viability assays. Pharmacological inhibition of HDAC7 in APP/PS1 mice was performed via intraperitoneal injection of TMP195, and the effects on neurotoxic reactive astrocytes, neuronal and synaptic loss, and behavioral performance were measured. HDAC7 was selectively upregulated in plaque-adjacent astrocytes in APP/PS1 mice. Overexpression of HDAC7 specifically in astrocytes was sufficient to induce a neurotoxic transcriptional profile, neuronal loss, and cognitive deficits in both WT and young APP/PS1 mice. Mechanistically, upon A\u03b2 stimulation, the upregulated HDAC7 directly interacted with and deacetylated IKK\u03b1 and IKK\u03b2, resulting in the activation of IKK, translocation of NF-\u03baB to the nucleus, and subsequent expression of neurotoxic genes. This neurotoxic conversion was dependent on IKK activity, as IKK inhibition nullified the effects in astrocytes overexpressing HDAC7. Conversely, astrocytic HDAC7 knockdown or treatment with TMP195 attenuated IKK-NF-\u03baB signaling, reduced\u00a0the presence of\u00a0neurotoxic reactive astrocytes, and rescued neurodegeneration and cognitive deficits in APP/PS1 mice. HDAC7 acts as an intrinsic effector within astrocytes, responding to A\u03b2 pathology and converting astrocytes into a neurotoxic state through direct interaction with IKK. Targeting HDAC7 presents a promising strategy for astrocyte-directed therapeutic interventions in Alzheimer's disease.\n\nID: 42329877\nTitle: Disentangling crossing fibers with advanced dMRI methods reveals bundle-specific degeneration across the visual system in asymmetric glaucoma.\nAbstract: Diffusion magnetic resonance imaging (dMRI) is a non-invasive neuroimaging technique that enables in vivo assessment of white matter microstructure and is highly sensitive to tissue alterations associated with disease. Although substantial evidence links diffusion-derived metrics to underlying white matter tissue properties, the presence of complex within-voxel axonal configurations complicates their biological interpretation. Several methods have been proposed to assess diffusion properties of individual crossing axonal populations, but their validation and clinical applicability remain limited. Glaucoma, the second leading cause of blindness worldwide, is characterized by progressive loss of retinal ganglion cells and axonal damage in the optic nerve, leading to degeneration along the entire visual pathway. This degeneration includes secondary effects on fiber crossings within the optic chiasm, which are challenging to characterize with conventional diffusion methods. Here, we evaluated whether advanced diffusion metrics can detect microstructural alterations in these complex white matter configurations and whether these measures correlate with clinical markers of glaucoma severity. In this study, we evaluated 31 patients with asymmetric glaucoma and 31 healthy controls using advanced diffusion magnetic resonance imaging methods, including Diffusion Tensor Imaging, Constrained Spherical Deconvolution, multi-tensor fit via Multi-Resolution Discrete Search method, and Fixel-Based Analysis. We found significant differences of diffusion metrics in white matter tracts of the visual system, including the optic nerve, optic chiasm, optic tracts, and optic radiations. Moreover, diffusion metrics correlated with clinical ophthalmological parameters such as cup-to-disc ratio, visual field mean deviation, and retinal nerve fiber layer thickness. These findings support the use of advanced diffusion magnetic resonance imaging models as sensitive tools for detecting Wallerian degeneration and resolving complex white matter architecture in the human visual pathway, and demonstrate their utility to study other fiber-crossing regions throughout the brain.\n\nID: 42326467\nTitle: Cerebrospinal fluid NPTX2/p-tau ratio as a biomarker for cognitive decline in neurodegenerative diseases.\nAbstract: Neuronal pentraxin 2 (NPTX2) and its use as a ratio with other synaptic proteins has emerged as a prognostic cerebrospinal fluid (CSF) biomarker across neurodegenerative diseases. Using a single molecule array (Simoa) method, CSF NPTX2 was measured in 688 individuals from the Sant Pau Initiative on Neurodegeneration, including Alzheimer's disease (AD), dementia with Lewy bodies (DLB), frontotemporal lobar degeneration-related disorders (FTLDrs), and cognitively unimpaired (CU) participants. NPTX2/phosphorylated-tau (p-tau)181 performance was compared to standalone NPTX2 and p-tau181. The NPTX2/p-tau ratio enhanced diagnostic performance of standalone NPTX2 and p-tau, particularly for DLB and FTLDrs (area under the curve [AUC]NPTX2/p-tau\u00a0=\u00a00.78-0.79 vs. AUCNPTX2\u00a0=\u00a00.63-0.70 and AUCp-tau\u00a0=\u00a00.59-0.75), and was more strongly associated with cognition. It also better predicted progression to dementia across the cohort (hazard ratio [HR]\u00a0=\u00a01.63), especially in AD (HR\u00a0=\u00a01.84) and DLB (HR\u00a0=\u00a01.50). NPTX2/p-tau may improve prognostic assessments in patients with cognitive impairment, outperforming standalone biomarkers.\n\nID: 42323468\nTitle: Oligodendrocyte Piezo2 is a regulator of age-dependent myelin integrity and dysregulated in multiple sclerosis.\nAbstract: Studies on the mechanosensitive ion channel Piezo2 largely focus on its role in the peripheral nervous system, particularly in touch and pain sensation. Here, we investigate Piezo2 function in the anterior visual pathway of the central nervous system with a focus on oligodendrocyte (OL) biology and myelin integrity. Using single-nucleus RNA sequencing, we identify Piezo2 expression in late differentiated OLs of the murine optic nerve, with minor expression in retinal ganglion cells. OL-specific Piezo2 deficiency results in age-dependent motor impairment and selective disruption of myelin compaction in small-caliber optic nerve axons, a fiber population known to be particularly vulnerable in demyelinating disease. Differential gene expression analysis further indicates that Piezo2 regulates myelin compaction and white matter integrity in mature OLs. Consistent with these findings, OL-encoded PIEZO2 expression is reduced in optic nerve lesion areas from multiple sclerosis patients, highlighting a convergent mechanism of small-caliber fiber vulnerability. Together, these data identify Piezo2 as an age-related regulator of OL function and myelin integrity, with potential relevance for preserving white matter structure in multiple sclerosis.\n\nID: 42317872\nTitle: Nutrients and bioactive compounds as modifiers of neurodegenerative trajectories: molecular mechanisms, translational barriers, and precision nutrition.\nAbstract: The Neurodegenerative diseases (NDs) such as Alzheimer's disease (AD), Parkinson's disease (PD), Multiple sclerosis (MS), and Amyotrophic lateral sclerosis (ALS) are a growing health burden across the world with minimal disease-modifying treatment and therapy. It is emerging that neurodegeneration is not only a progressive loss of neurons, but also a nutrient-sensitive systems-level dysfunction that takes the form of redox imbalance, chronic neuroinflammation, mitochondrial dysfunction, impaired proteostasis, and synaptic loss. The aging brain are more prone to metabolic vulnerability, and subclinical deficiencies in essential nutrients and bioactive dietary compounds may exacerbate cellular stress responses that contribute to disease progression. It summarizes the existing data on the effects of nutrients like vitamins, minerals, polyunsaturated fatty acids, and various phytochemicals in modulating neuronal homeostasis by regulating oxidative signaling, inflammatory cascades, mitochondrial resilience, autophagy, and synaptic plasticity. These nutrient-mediated effects collectively influence neuronal survival, synaptic integrity, and cognitive function by affecting disease susceptibility and progression. Additionally newer metabolites of the marine and microbiome act as new neuroactive agents. The evidence from in-vitro and preclinical models, translation to clinical benefit remains inconsistent due to heterogeneity in study design, bioavailability, blood- brain barrier penetration, dosing strategies and disease stage. This review highlights emerging potential of precision nutrition frameworks that integrate nutrigenomics, metabolomics, and microbiome interactions, and individualized metabolic profiling to enable context-dependent and stage-specific interventions. Moreover, conceptualizing neurodegeneration as a nutrient-sensitive, systems level disorder, propose a mechanistically informed and integrative approach that combine targeted nutritional strategies with pharmacological and lifestyle therapies to more effectively modify neurodegenerative trajectories.\n\nID: 42317267\nTitle: Vascular regeneration and blood flow recovery in glaucoma.\nAbstract: The retina and optic nerve rely on a tightly regulated neurovascular unit that sustains the highly dynamic and metabolically demanding neural tissues required for vision. Adequate oxygen and nutrient delivery are essential for maintaining tissue function and cellular survival. Over the past decades, extensive research within and beyond the field of ophthalmology has sought to elucidate the mechanisms that govern neurovascular regulation in health and disease. Growing evidence indicates that neurovascular dysfunction plays an important role in both the initiation and progression of glaucoma, a leading cause of irreversible blindness worldwide. Alterations in vascular architecture and blood flow may compromise the metabolic support required by retinal ganglion cells, increasing their vulnerability to injury and degeneration. While neurons possess limited regenerative capacity, the vascular system retains a remarkable degree of plasticity and is therefore amenable to repair. This vascular plasticity presents an opportunity to develop therapeutic strategies aimed at restoring vascular architecture and improving blood flow, complementing existing approaches focused on intraocular pressure reduction, neuroprotection, axonal regeneration, and/or neuronal transplantation. In this review, we summarize the current understanding of neurovascular function in the healthy eye, discuss mechanisms that contribute to vascular compromise in glaucoma, and highlight emerging avenues for promoting vascular regeneration and blood flow recovery. By identifying key knowledge gaps and future research priorities, we aim to outline promising directions for targeting the ocular neurovasculature to preserve retinal ganglion cell function and slow or stop progressive vision loss.\n\nID: 42313307\nTitle: Microglia-driven neuroinflammatory signaling in neurodegeneration: mechanisms and therapeutic opportunities.\nAbstract: Neuroinflammation has been identified as a major component to the pathogenesis and progression of many neurodegenerative illnesses, going beyond its traditional role as a protective immune response within central nervous system (CNS). There is growing evidence that persistent activation of peripheral immune pathways, microglia and astrocytes causes progressive neurodegeneration, synaptic loss and progressive neurodegeneration. This review examines the mechanisms of microglia- driven neuroinflammatory signaling and its involvement in major neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and Huntington's disease. Key neuroinflammatory mechanisms covered in depth including microglial activation, astrocyte reactivity, peripheral immune cell infiltration, cytokine dysregulation, and blood brain barrier (BBB) disruption. This review also emphasizes the role of neuroinflammation in acute neurological symptoms and mental and cognitive impairments. Glial activation markers, inflammatory cytokines, BBB proteins and kynurenine pathway metabolites are emerging as promising biomarkers for disease diagnosis and monitoring. Additionally, the potential of new mathematical and systems level computational models to describe intricate neuroimmune interactions and forecast the course of disease and treatment results is investigated. Current and emerging therapies targeting neuroinflammation include anti-inflammatory and immunomodulatory drugs, lifestyle interventions, stem cell approaches, gene-editing technologies and nanoparticle-based drug delivery systems. Despite significant progress, translating preclinical findings into effective clinical therapies remains challenging. Future developments in integrative neuroimmune modeling, biomarker-guided therapies and precision medicine may make it possible to create individualized treatments plans targeted at reducing neuroinflammation and enhancing the course of neurodegenerative illnesses.\n\nID: 42304799\nTitle: Pathogenic Modulation of Organelle Crosstalk in Helicobacter pylori-Associated Neurodegeneration.\nAbstract: Neurological disorders are increasingly linked to dysfunction of key cellular organelles, including mitochondria, endoplasmic reticulum (ER), lysosomes, endosomes, and peroxisomes. These organelles coordinate essential neuronal processes via tightly regulated crosstalk. Disruption in one organelle can propagate dysfunction across others, amplifying neurodegenerative cascades. Emerging evidence suggests that neurological diseases can result not only from disturbances in brain homeostasis but also from imbalances in gut homeostasis, highlighting the significant role of the gut-brain axis in maintaining neurological health. Helicobacter pylori, a gut pathogen contribute to the progression of neurological modalities by its secretome comprising Vac A, CagA, urease, and outer membrane vesicles via perturbing organelle function. These virulence factors induce mitochondrial fragmentation, ER stress, lysosomal dysfunction, and impaired mitophagy, disrupting organelle networks and promoting synaptic loss and neuronal death. Understanding how pathogen-induced organelle stress contributes to neurodegeneration offers novel insights into infection-driven brain disorders.\n\nID: 42304151\nTitle: The Impact of Preoperative Blood Glucose Control on Corneal Recovery and Visual Function After Phacoemulsification in Diabetic Cataract Patients.\nAbstract: Diabetic patients are at an increased risk for cataract and may experience delayed postoperative recovery due to diabetes-related ocular tissue vulnerability. However, the impact of preoperative glycemic control on early surgical outcomes and quality of life remains to be fully elucidated. This study aimed to investigate the effects of preoperative fasting blood glucose (FBG) control on postoperative corneal recovery, visual function, and vision-related quality of life in type 2 diabetic patients undergoing phacoemulsification. In this retrospective analysis, 197 cataract patients with type 2 diabetes who underwent phacoemulsification between March 2023 and March 2025 were included. Based on their preoperative FBG levels, they were divided into a well-controlled group (FBG <6.1 mmol/L, n = 83) and a poorly controlled group (FBG \u22656.1 mmol/L, n = 114). National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25), mean corneal astigmatism, corneal edema recovery, and best corrected visual acuity (BCVA) were compared between the two groups. Postoperatively, the well-controlled group had significantly higher total scores and scores on all dimensions of the NEI-VFQ-25 scale than the poorly controlled group (all p < 0.05). Regarding corneal recovery, the group with better control showed greater changes in mean corneal astigmatism on postoperative days 7 and 30 (p < 0.001). The corneal transparency ratio was higher on postoperative day 7 (p = 0.006), while there was no significant difference between the two groups on postoperative day 30. On postoperative day 7, the logarithm of the minimum angle of resolution (logMAR) BCVA of the well-controlled group was also significantly better than that of the poorly controlled group (p < 0.001). By postoperative day 30, the differences in corneal transparency and BCVA between the two groups became non-significant (p > 0.05). Good preoperative glycemic control in diabetic patients undergoing phacoemulsification is associated with faster early corneal edema resolution, better early visual recovery, and clinically meaningful improvements in vision-related quality of life. These findings underscore the importance of enhanced perioperative glycemic management to optimize short-term surgical outcomes and health-related quality of life in this population.\n\nID: 42302828\nTitle: TGF-\u03b2 signaling promotes astroglial activation and TDP-43 proteinopathy in organoid models of frontotemporal lobar degeneration.\nAbstract: Dominant mutations in progranulin (GRN) gene cause frontotemporal lobar degeneration (FTLD-GRN), whereas homozygous GRN mutations lead to neuronal ceroid lipofuscinosis, a childhood neurodegenerative disorder. While recent transcriptomic studies reveal profound glial and neuronal pathology in FTLD-GRN at the disease end stage, the mechanism that disrupts glia-neuron homeostasis remains unclear. Using induced pluripotent stem cell-derived cortical organoids, we showed that GRN-/- and GRNR493X mutations led to precocious astrogliosis that promoted neuronal stress and synaptic loss. Single-cell transcriptomics and histopathology analyses revealed a robust activation in the TGF-\u03b2 signaling pathway in GRN-/- and GRNR493X/R493X astrocytes, which was accompanied by features of immune activation, loss of synaptic support, and abundant pTDP-43+ fibrils in astroglial cytoplasm, a feature characteristic of FTLD-GRN. Intriguingly, blocking TGF-\u03b2 signaling mitigated astroglial activation and pTDP-43 proteinopathy in GRN-/- organoids. Together, these results provide insights into the cell-autonomous role of astroglial activation in neurodegeneration caused by progranulin deficiency.\n\nID: 42294809\nTitle: Microplastics-Induced Gut Microbiota Dysbiosis Accelerates Alzheimer's-Like Pathology and Cognitive Decline via the Gut-Brain Axis.\nAbstract: Alzheimer's disease (AD) is incurable and increasingly attributed to gene-environment interactions. Microplastics (MPs) are omnipresent in the human food chain, yet their impact on neurodegeneration is largely unknown. Here we show that chronic oral exposure to 2-\u00b5m amine-modified polystyrene microparticles accelerates cognitive decline, amplifies A\u03b2 deposition, gliosis, and synaptic loss, and cripples autophagic flux in 5XFAD mice through the gut-brain axis. MPs accumulate in the gut, breach the epithelial barrier, and selectively expand the taurine-depleting pathobiont Bilophila, while suppressing taurine-synthesizing commensals. Untargeted metabolomics reveal a systemic taurine deficit that precedes and predicts exacerbated A\u03b2 deposition, gliosis, synaptic loss, and autophagic blockade in 5XFAD mice. Antibiotic-mediated microbiota ablation and fecal microbiota transplantation (FMT) demonstrate that the neurotoxic phenotype is fully microbiota-dependent. Restoring taurine level rebalances microglial homeostasis, reinstates autophagic flux, and rescues memory deficits in MPs-treated 5XFAD mice. Translational validation using Alzheimer's Disease Neuroimaging Initiative (ADNI) plasma shows taurine is significantly lower in AD patients versus cognitively normal controls and inversely correlates with cognitive decline. Our findings identify MPs-induced gut-microbiota dysbiosis as a modifiable environmental driver of AD pathogenesis and establish taurine supplementation as a readily translatable intervention that simultaneously fortifies the intestinal barrier and neutralizes microbiota-mediated neurodegeneration.\n\nID: 42292332\nTitle: Microglial regulation of synaptic plasticity in transsynaptic degeneration of glaucoma.\nAbstract: Glaucoma is a heterogeneous group of irreversible and blinding optic neuropathies caused by multiple factors. It is clinically characterized by progressive loss of visual field and decline in visual acuity, ultimately culminating in complete blindness. Hallmark pathological features include progressive degeneration of retinal ganglion cells and atrophy of the optic nerve. Importantly, the pathological process of glaucoma extends far beyond the eyeball, involving transsynaptic degeneration across the entire visual pathway. Microglia, as the principal immune regulators of the central nervous system, serve as the earliest sensors and effectors in the pathogenesis of glaucoma. By modulating synaptic plasticity, microglia contribute to synaptic loss and the disruption of neural circuits. They also play essential roles in maintaining neural tissue homeostasis. This review summarizes current evidence and underlying mechanisms of bidirectional transsynaptic degeneration in glaucoma. It highlights that targeting microglial functional homeostasis, particularly their regulation of synaptic plasticity, may be a promising strategy to mitigate glaucoma-associated transsynaptic degeneration and promote central neuroprotection.\n\nID: 42290955\nTitle: Regulation of NMDA receptor interactions with the actin cytoskeleton in dendritic spine development.\nAbstract: In the central nervous system, the majority of excitatory synapses exist on small actin-enriched structures protruding from dendrites, known as dendritic spines. Actin cytoskeletal rearrangements drive dynamic changes in spine shape, size, and density depending on developmental stage and synaptic activity. Spines initially emerge from the dendritic shaft as dynamic protrusions known as filipodia-like spines, which serve as precursors to mature dendritic spines. The formation and maturation of dendritic spines facilitate information transfer in neural circuits, underlying cognitive processes, such as learning and memory formation, and altered spine development results in neurodevelopmental disorders. Within dendritic spines, signaling events are regulated by many synaptic receptors such as the ionotropic N-methyl-D-aspartate (NMDA) and \u03b1-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors. However, only NMDA receptors are enriched in both immature filopodia-like spine precursors and mature dendritic spines, with AMPA receptors expressed later in development and coinciding with spine maturation. During embryonic development, most NMDA receptors contain GluN2B subunits, in contrast to mature synapses which predominantly contain GluN2A subunits. While many actin regulatory proteins, such as \u03b1-actinin-2, interact with NMDA receptor subunits, it remains unclear whether GluN2B vs. GluN2A-containing receptors exhibit differences in their preferential protein interactions that underly dendritic spine development. The following review highlights how preferential interactions between specific GluN2 isoforms and actin cytoskeletal regulators underlie synaptic development by balancing dynamic events of synaptic plasticity with competing events of synaptic strengthening and consolidation. We discuss how alterations in the expression of GluN2 isoforms and/or mutations that disrupt actin interactions contribute to neurological disorders, both developmental and degenerative.\n\nID: 42285687\nTitle: Nuciferine ameliorates cognitive impairment and insulin resistance in T2DM by targeting the insulin receptor and activating PI3K/AKT signaling.\nAbstract: Insulin resistance is a hallmark of type 2 diabetes (T2DM) and can increase the risk of cognitive impairment, including Alzheimer's disease. Nuciferine, an alkaloid derived from lotus leaves, shows neuroprotective effects. This study investigated nuciferine's protective role in T2DM-induced cognitive impairment (T2DM-CI) and its mechanisms. Mouse models were created using high-fat diets and streptozotocin, along with high glucose-induced HT-22 cells. Nuciferine reduced blood glucose, improved cognitive function, and mitigated glial cell activation, neuron and synapse loss in T2DM mice. It enhanced insulin signaling by increasing protein levels of IR, IRS1, and IGF-1R, reversing PI3K and AKT phosphorylation, inhibiting GSK3\u03b2 activity, and reducing hyperphosphorylated Tau in HT-22 cells and T2DM mice. mRNA levels of these molecules matched their protein levels. Further studies revealed that nuciferine directly interacts with IR, knocking out IR abolished its effects on the PI3K/AKT pathway. Thus, nuciferine activates the PI3K/AKT pathway via IR, improving insulin resistance and slowing T2DM-CI progression.\n\nID: 42281784\nTitle: Intravitreal delivery of NGF-chitosan hydrogel confers retinal ganglion cell protection and visual function recovery in experimental glaucoma.\nAbstract: Glaucoma is one of the leading causes of irreversible blindness, and lowering intraocular pressure alone is insufficient to rescue lost retinal ganglion cells (RGCs) or restore visual function. In this study, we intravitreally injected a liquid chitosan gel loaded with nerve growth factor (NGF), previously developed by our group, into the vitreous body of rats with ocular hypertension-induced glaucoma. Using a combination of techniques--including multiplex immunofluorescence staining, TUNEL staining, CTB tracing, Western blotting, visual electrophysiology, and behavioral assessments--we demonstrated that, compared with the lesion control (LC) group, the NGF-chitosan hydrogel significantly enhanced RGC survival following glaucomatous injury (by approximately 27%), preserved dendritic architecture and long-distance axonal projections, and promoted recovery of visual function. Mechanistically, treatment with the NGF-chitosan hydrogel upregulated the expression of NGF and its high-affinity receptor, tropomyosin receptor kinase A (TrkA), in the retina. In addition, it suppressed retinal glial activation and enhanced mammalian target of rapamycin (mTOR) signaling, collectively contributing to RGC protection and repair. Notably, we further observed activation of Nestin+ neural stem cells in the ciliary body region, along with their differentiation into BrdU+/Brn3a+ neuron-like cells; the precise mechanisms underlying this phenomenon warrant further investigation. In conclusion, intravitreal delivery of NGF-chitosan hydrogel provides novel mechanistic insights and represents a promising therapeutic strategy for the treatment of glaucoma.\n\nID: 42270085\nTitle: Lewy Bodies Are Not Associated With Neuronal or Synaptic Loss in Dementia With Lewy Bodies.\nAbstract: The misfolding and accumulation of the protein \u03b1-synuclein (\u03b1Syn) into cytoplasmic inclusions termed Lewy bodies (LBs) and Lewy neurites is the defining neuropathological feature of LB diseases, such as Parkinson's disease (PD) and dementia with Lewy bodies (DLB). The loss of neurons and/or synapses has been postulated to underlie the clinical syndrome of DLB. The present study sought to elucidate the relationship between LB burden and neuronal and synaptic loss in DLB. Post-mortem brain tissue from the cingulate gyrus and inferior temporal gyrus, two regions vulnerable to LB pathology, was obtained from DLB (N\u2009=\u200920) and control cases (N\u2009=\u200920). Formalin-fixed paraffin-embedded tissue was stained to quantify LB, Alzheimer-type pathology and a neuronal marker. Frozen tissue from the contralateral hemisphere was processed for immunoblotting to compare the abundance of synaptic markers across cases. Across both regions, no evidence of reduced total neuronal density was observed, but a modest reduction in parvalbumin interneurons was observed in the cingulate gyrus, and there were only modest reductions in some synaptic markers in DLB. LB burden was markedly variable across DLB cases but was not associated with any synaptic marker abundance or neuronal density. Taken together, these findings do not support an association between LB density and neuronal or synaptic loss in DLB, even in regions with particularly high burdens of LBs, such as the cingulate gyrus. These findings suggest that the link between \u03b1Syn proteinopathy and disease requires further investigation.\n\nID: 42461932\nTitle: Structure function relationships differ between optic neuritis and glaucoma with comparable optical coherence tomography findings.\nAbstract: This retrospective study compared structure-function relationships between patients with optic neuritis (ON) and primary open-angle glaucoma (POAG), focusing on the extent of retinal nerve fiber layer (RNFL) and ganglion cell-inner plexiform layer (GCIPL) damage and its correlation with visual field (VF) defects. We included 194 patients (ON: 47; POAG: 147) referred to Yonsei University Severance Eye Hospital between 2017 and 2023. RNFL and GCIPL thickness, VF indices, and the relationship between structural and functional measures were assessed. Despite comparable RNFL and GCIPL thinning, ON demonstrated significantly better VF performance than POAG (mean deviation: -2.26 dB vs. -7.32 dB; VF index: 95.48% vs. 80.43%; both p\u2009<\u20090.001). In POAG, VF loss was strongly correlated with structural parameters, whereas in ON, VF remained preserved even at low RNFL and GCIPL values. Linear regression with robust error estimation confirmed significant interaction between disease type and structure-function slopes (p\u2009<\u20090.01). These findings persisted after 1:2 propensity score matching for age and comorbidities (ON: n\u2009=\u200929; POAG: n\u2009=\u200958; all interaction p\u2009<\u20090.05), age-adjusted multivariable regression, and a sensitivity analysis restricted to non-diabetic participants (ON: n\u2009=\u200945; POAG: n\u2009=\u2009124; all interaction p\u2009<\u20090.001). This dissociation was evident at RNFL <90 \u00b5m and GCIPL <80 \u00b5m, where ON showed better VF indices than POAG with similar structural loss. The differences in structure-function relationships underscore the importance of disease-specific diagnostic approaches and unraveling the distinct mechanisms underlying ON and POAG to improve the management of visual impairments.\n\nID: 42460311\nTitle: Genomic landscape of Mexican patients with maturity onset diabetes of the young: beyond mutations in MODY-known genes.\nAbstract: Maturity Onset Diabetes of the Young (MODY) remains an underdiagnosed condition with remarkable genetic variability across populations. While diagnostic tools are based on Caucasian cohorts, Whole Exome Sequencing (WES) studies are needed to identify new genes in non-Caucasians, as up to 77% of patients do not harbor variants of significance in MODY-known genes. No WES studies have addressed the genomic landscape of MODY beyond its canonical genes in Latino populations. We aimed to characterize the genomic landscape of MODY through WES in a Mexican cohort, comparing cases with type 2 diabetes mellitus (T2DM) patients and healthy controls (HC). WES was performed in 17 patients with MODY, 17 with T2DM and 17 HC. We compared the single nucleotide variant landscape across groups in MODY-known genes and searched for genetic variants with differential enrichment across groups. MODY genes used for routine diagnosis showed low discrimination utility, as patients with MODY, T2DM and HC harbored genetic variants in MODY-known genes at similar frequencies in most cases. We found 14 genes with variants capable of distinguishing MODY from T2DM and HC. Variants in genes such as MAP2K3, SYT15, KCNJ12, PEX5, and TPTE were found in 75-100% of MODY cases while absent in T2DM and HC. Enrichment analysis revealed involvement in synaptic vesicle trafficking, insulin/IGF pathway-mitogen activated protein kinase kinase/MAPK, and insulin/IGF pathway-protein kinase B/AKT signaling. MODY presents a complex genetic architecture in the Mexican population. Besides improving our understanding of glycemic regulation pathways, identified genes may serve as diagnostic biomarkers.\n\nID: 42452492\nTitle: Nose-to-Eye Delivery: The Potential of Intranasal Administration in Ophthalmology.\nAbstract: Non-invasive drug delivery for ocular diseases remains a significant challenge in ophthalmology, as conventional eye drops offer less than 5% bioavailability due to pre-corneal barriers and the corneal epithelium. This review explores the intranasal (IN) route as a promising strategy for targeting both the anterior and posterior segments of the eye. The IN route leverages several distinct pathways: the nasolacrimal reflex for remote physiological stimulation; the \"neural bridge\" through the cribriform plate, allowing direct perineural and vascular transport via the olfactory and trigeminal nerves to bypass the blood-retinal barrier; and systemic absorption that avoids hepatic first-pass metabolism. Pre-clinical evidence indicates that IN administration of agents such as erythropoietin, nerve growth factor, and insulin achieves superior retinal concentrations compared to topical or systemic dosing, offering neuroprotection in models of retinal degeneration and glaucoma. Clinically, varenicline nasal spray is already FDA-approved for dry eye disease, while intranasal steroids demonstrate a favorable ocular safety profile without significantly increasing intraocular pressure. Although limited by mucociliary clearance and small delivery volumes, the IN route offers a painless, non-invasive alternative to intraocular injections, potentially enhancing patient compliance. Future advancements in mucoadhesive nanocarriers are essential to optimize drug residence time and realize the full potential of nose-to-eye delivery in chronic ophthalmic care.\n\nID: 42432940\nTitle: Sector-dependent device discordance of RNFL measurements: A prospective cross-sectional study of cross-platform variability and interchangeability in glaucoma monitoring.\nAbstract: This study aimed to characterize intra-device repeatability and sector-dependent inter-device variability of peripapillary retinal nerve fiber layer (RNFL) measurements across 5 optical coherence tomography (OCT) platforms and define the concept of sector-dependent device discordance, the non-uniform distribution of inter-device measurement bias across anatomical RNFL sectors. This prospective cross-sectional study included 38 healthy participants who underwent peripapillary RNFL imaging using 5 OCT devices: Heidelberg Spectralis, TowardPi BMIZAR 400\u2009kHz swept-source OCT, Huvitz HOCT-1/1F, NIDEK RS-1 Glauvas, and Topcon Maestro 2. RNFL thickness was analyzed in the superior, nasal, inferior, and temporal sectors, as well as global mean thickness. Three consecutive measurements were obtained for each eye with each device to assess intra-device repeatability. Repeatability was evaluated using repeated-measures analysis of variance. Inter-device reliability was assessed using intraclass correlation coefficients, with Heidelberg Spectralis as the reference. Agreement between devices was further evaluated using Bland-Altman analysis. Excellent intra-device repeatability was documented across all platforms. However, marked inter-device variability demonstrated sector-dependent patterns: global RNFL measurements showed moderate agreement (intraclass correlation coefficient: 0.346-0.805), while nasal and temporal sectors exhibited disproportionately higher variability (absolute percentage error up to 20.76% in the nasal sector; limits of agreement width ranging from 20.23% to 35.52% in temporal). Bland-Altman analyses revealed device-specific bias signatures (Huvitz HOCT-1/1F: -8.17% global bias; NIDEK RS-1 Glauvas: +10.59%; Topcon Maestro 2: -4.47%), indicating systematic, reproducible platform-inherent differences rather than random measurement noise. While intra-device repeatability is excellent, inter-device RNFL measurements remain substantially discordant, particularly in nasal and temporal sectors, where absolute percentage error reaches up to 20.76% and limits of agreement exceed 35%, a phenomenon termed sector-dependent device discordance. Global RNFL measurements may appear concordant while sectoral measurements diverge, creating a theoretically plausible risk for false progression detection, pending validation in glaucomatous eyes. RNFL measurements are not interchangeable across platforms and are particularly unreliable for sector-specific assessment. Device-consistent monitoring is essential for glaucoma follow-up; multicenter studies and device switching scenarios warrant platform-specific normalization strategies.\n\nID: 42402345\nTitle: Propionic acid in multiple sclerosis: a phase 2b, double-blind, randomized placebo-controlled trial.\nAbstract: Propionic acid (PA), a microbial-derived short-chain fatty acid, contributes to intestinal barrier integrity, systemic immune regulation, and neuronal function. Individuals with multiple sclerosis show reduced PA levels, and open-label data have suggested beneficial immunomodulatory and clinical effects of supplementation. The Multiple sclerosis And DisAbility Improvement (MADAI) trial was a randomized, double-blind, placebo-controlled, single-centre, phase 2b study designed to evaluate the efficacy and safety of PA as an add-on therapy in adults with clinically stable multiple sclerosis. Between April 5 and 29 May 2024, 101 adults (64% women; mean age 45 years) were randomly assigned in a 2:1 ratio to receive PA 500\u2005mg twice daily or matching placebo for 90 days. The primary outcome was the change in serum neurofilament light chain (sNfL) concentration, a biomarker of neuroaxonal damage, adjusted for age, body mass index, creatinine, and baseline sNfL. Secondary outcomes included physical and cognitive performance measures and patient-reported outcomes, including fatigue and quality of life scores. sNfL levels were significantly reduced in the PA group {-17.9%; from 9.77\u2005pg/ml [95% confidence interval (CI) 9.00 to 10.60] to 8.02\u2005pg/ml (95% CI 7.36 to 8.73); mean difference 1.75\u2005pg/ml (95% CI 0.9 to 2.6); P = 0.000025}, while no significant change was observed in the placebo group. The adjusted mean difference in sNfL levels between the PA and placebo groups at follow-up was 0.91\u2005pg/ml (95% CI 0.02 to 1.79; P = 0.045). Reductions in sNfL were also observed among participants in the PA arm receiving moderate-to-high efficacy disease-modifying therapies (n = 41; P = 0.0001), including those on anti-CD20 treatment (n = 27; P = 0.0005). There was a trend towards improvement in motor fatigue in the PA group. No serious adverse events related to the study medication occurred. PA supplementation was well tolerated and associated with significant reductions in sNfL, suggesting attenuation of neuroaxonal injury in multiple sclerosis. These findings support further evaluation of PA as an add-on treatment in larger, long-term studies.\n\nID: 42398402\nTitle: Discovery of novel ROCK inhibitors RX-021 and RX-044 with intraocular pressure-lowering effect for glaucoma treatment.\nAbstract: Through systematic optimization of lead D25, we identified two novel ROCK inhibitors, RX-021 and RX-044. Maintaining DFG interactions while optimizing linker flexibility was critical for potency. RX-044 showed excellent ROCK1/2 inhibition (IC50\u202f=\u202f10.01 and 9.68\u202fnM), favorable kinase selectivity, and no cytotoxicity in HTM cells. In a mouse ocular hypertension model, RX-021 achieved superior IOP reduction (5.38\u202f\u00b1\u202f1.51\u202fmmHg at 4\u202fh) versus (S)-Netarsudil, with sustained 24\u202fh efficacy and reversible HTM cell effects. Both compounds provided significant retinal neuroprotection, preserving retinal ganglion cell survival, restoring electroretinography responses, and ameliorating histopathological changes. Slit-lamp exams confirmed that initial ocular irritation subsided with extended dosing. These findings establish RX-021 and RX-044 as promising novel ROCK inhibitors with enhanced IOP-lowering efficacy and good retinal protective effects for glaucoma therapy.\n\nID: 42390172\nTitle: Spatial Decomposition of Longitudinal RNFL Maps Reveals Distinct Modes of Glaucomatous Progression With Structure-Function and Genetic Signatures.\nAbstract: To determine whether spatial decomposition of longitudinal retinal nerve fiber layer (RNFL) change maps reveals distinct modes of glaucomatous progression masked by conventional averaging, and to validate these modes through structure-function mapping and genetic association analysis. Pixel-wise RNFL rates of change were computed from longitudinal optic disc OCT scans of 15,242 eyes (8419 adults with POAG; Massachusetts Eye and Ear, 1998-2023). A loss-only constraint zeroed all thickening values, reflecting the biological prior that adult RNFL does not regenerate. Non-negative matrix factorization decomposed these maps into spatial progression components (80% training set). Components were evaluated in a held-out set (20%) for retinotopic structure-function concordance, visual field progressor classification against global and quadrant RNFL rates, and enrichment of genetic association signals at established POAG loci. Six anatomically distinct progression patterns emerged, including diffuse circumferential loss, focal peripapillary defects, and arcuate bundle degeneration. Pattern-based models provided significant incremental predictive information over global RNFL rate (integrated discrimination improvement, 0.049; P = 0.003), with concordant gains in discrimination (area under the curve, 0.795 vs. 0.768) and variance explained (pseudo-R\u00b2, 0.382 vs. 0.311). Structure-function mapping confirmed retinotopic coherence. In an exploratory genetic analysis, spatial pattern weights showed stronger association signals than the global RNFL rate at the majority of established POAG susceptibility loci, consistent with the hypothesis that spatial decomposition may reduce phenotypic heterogeneity. Glaucomatous structural progression occurs through spatially distinct modes with independent structure-function and preliminary genetic signatures that conventional RNFL averaging obscures.\n\nID: 42383814\nTitle: Unsupervised Clustering for POAG Phenotyping.\nAbstract: To identify and characterize clinically meaningful phenotypic subtypes of POAG using unsupervised clustering of multimodal clinical data. This retrospective cohort study included 4274 eyes from 4274 patients aged \u226540 years with POAG. Twenty-one clinical features encompassing visual field indices and progression slopes, retinal nerve fiber layer (RNFL) thickness, optic nerve head parameters, and IOP level and variability were analyzed. Hierarchical clustering, K-means, and fuzzy C-means algorithms were applied, with stability assessed via internal validation metrics and visual field archetypal analysis. Five reproducible POAG phenotypes were identified The. k-means and fuzzy C-means performed best (Calinski-Harabasz 731.76 and 731.43; Davies-Bouldin 1.59 and 1.60), with excellent pairwise agreement between them (\u03ba = 0.97) compared with moderate agreement with hierarchical clustering (\u03ba \u2248 0.55), and high overall stability (mean Adjusted Rand Index, 0.98 \u00b1 0.02). Clusters 1 and 2 represented mild, stable phenotypes (mean deviation [MD] slopes of +0.14 and +0.10 dB/year), differing primarily in IOP burden. Cluster 3 showed structural-functional dissociation-significant RNFL thinning (71.40 \u00b1 8.14 \u00b5m) despite limited functional progression (MD slope +0.08 dB/year). Cluster 4 exhibited the most aggressive course, with rapid functional decline (MD slope of -0.98 \u00b1 0.58 dB/year), greatest IOP variability (3.88 \u00b1 1.82 mm\u00a0Hg), and advanced structural loss (RNFL 64.44 \u00b1 10.05 \u00b5m). Cluster 5 demonstrated advanced baseline damage (MD of -15.28 \u00b1 4.72 dB; RNFL, 62.87 \u00b1 9.53 \u00b5m) with relative longitudinal stability. Visual field archetypes aligned with cluster-specific severity. Multimodal clustering identifies distinct POAG phenotypes, supporting improved risk stratification and targeted management.\n\nID: 42383239\nTitle: Aptamers in Ocular Disease Therapy and Drug Delivery: Current Progress and Future Opportunities.\nAbstract: Aptamers are single-stranded oligonucleotides with the ability to bind specific target molecules with high affinity and selectivity, positioning them as valuable tools for precision therapeutics and targeted drug delivery. In ophthalmology, aptamer-based platforms have emerged as effective solutions for managing retinal diseases, glaucoma, and ocular surface disorders. This review provides a comprehensive overview of aptamers that have received approval or are in experimental, preclinical, or clinical development stages for ocular diseases. A narrative literature search was conducted using PubMed, Scopus, Cochrane Library, Embase, and Web of Science databases, concentrating on aptamers that have reached experimental, preclinical, clinical, or FDA-approved stages. Studies published up to March 2026 were screened according to predefined inclusion and exclusion criteria, based on their reported efficacy, molecular targets, and relevance to ocular diseases. Twenty-four records were included, comprising 24 aptamer-based platforms. Across ocular diseases, aptamers were identified in three principal application domains: therapeutic intervention, diagnostic, and targeted drug delivery. In age-related macular degeneration, aptamers development was predominantly therapeutic, with agents targeting vascular endothelial growth factor, platelet-derived growth factor, fibroblast growth factor 2, complement components, nucleolin, CBF1, and CD44. In glaucoma, aptamers were mainly directed toward neuroprotection, antifibrotic modulation, aqueous humor outflow regulation, biomarker detection, and topical drug delivery. In ocular surface diseases, aptamers were primarily developed for antimicrobial and antiviral therapy, antiangiogenic treatment, anti-allergic modulation, corneal surface targeting, and controlled topical drug delivery. Overall, aptamers demonstrated broad translational versatility across both posterior and anterior segment diseases. The available evidence demonstrates a diverse and rapidly expanding repertoire of aptamers developed for ocular diseases, underscoring their versatile potential as next-generation platforms for therapeutic, biomarker-guided diagnosis, and targeted drug delivery in ophthalmology.\n\nID: 42380927\nTitle: Adipose stem cells derived extracellular vesicles alleviate retinal excitotoxicity via miR-23a-5p/PLCD1/PKCA/GluA2 axis: a potential therapeutic strategy.\nAbstract: Despite excitotoxicity being a pivotal pathological mechanism in various retinal diseases, effective clinical interventions remain limited. Previous study has shown that adipose stem cell-derived extracellular vesicles (ADSC-EVs) can alleviate glutamate-induced retinal ganglion cells (RGCs) death by suppressing protein kinase C alpha (PKCA) pathway and increasing the expression of \u03b1-amino-3-hydroxy-5-methyl-4-isoxazoleproprionic acid receptors (AMPARs) subunit 2 (GluA2) on the cell membrane, but the mechanisms remain unexplored. To clarify the molecular processes involved in ADSC-EVs-mediated intracellular calcium balance, we isolated ADSC-EVs using ultrafiltration and ultracentrifugation, and characterized these vesicles by transmission electron microscopy, nanoparticle tracking analysis, and flow cytometry. Small RNA sequencing was performed on glutamate-injured rat retinal precursor (R28) cells pre-treated with ADSC-EVs or PBS. Through bioinformatic analysis, we identified candidate microRNAs and predicted their potential target genes. The regulatory effects of microRNA were confirmed using propidium iodide staining, Fluo-4AM staining, western blotting, and immunofluorescence. Additionally, the RGCs counting and visual function tests were employed to evaluate the therapeutic efficacy of the microRNA in the glutamate-induced SD rat - animal model. Our results demonstrated that pre-treatment with ADSC-EVs led to a significant increase in the expression levels of miR-127-3p, miR-181b-1-3p, miR-199a-3p/5p, miR-23a-5p, miR-23b-5p, and miR-486 in R28 cells. Bioinformatic analyses suggest that miR-23a-5p may contribute to regulating the calcium overload by inhibiting the expression of phospholipase C delta 1 (PLCD1). Overexpression of miR-23a-5p or pre-treatment with ADSC-EVs modulated the expression of GluA2 on the cell membrane through inhibiting the PLCD1/PKCA/GluA2 axis, thereby reducing intracellular calcium levels and diminishing R28 cell death. In contrast, inhibition of miR-23a-5p expression partially reversed the regulatory effects of ADSC-EVs on calcium concentration and cell viability. Furthermore, our findings suggest that overexpression of miR-23a-5p in retina alleviated glutamate-induced RGCs death and visual function impairment, whereas suppression of miR-23a-5p exacerbated glutamate-induced RGCs death. ADSC-EVs delived miR-23a-5p mitigate glutamate-induced RGCs damage by inhibiting the PLCD1/PKCA/GluA2 axis. Targeting this miR-23a-5p-mediated axis may therefore represent a promising therapeutic approach for excitotoxic RGCs injury.\n\nID: 42379865\nTitle: [Regulation of SARM1 on SNPH expression and its participation in glaucomatous optic neuropathy].\nAbstract: Objective: To investigate the molecular mechanism of toll-like receptor adaptor protein SARM1 in glaucomatous optic neuropathy. Methods: The experimental study was conducted from February 2024 to October 2025. A chronic ocular hypertension glaucoma model was established by injecting micro-magnetic beads into the anterior chamber of 8- to 10-week-old male Wistar rats. At 3 days, 1 week, and 2 weeks post-modeling, retinal and optic nerve tissues from 6 eyes of 6 rats were collected as the chronic ocular hypertension glaucoma model group, and 6 eyes from 6 wild-type rats that received an equal volume of saline via anterior chamber injection served as the control group. Intraocular pressure was measured using a TonoLab tonometer. Retinal whole-mounts were prepared and POU domain class 4 transcription factor 1 (POU4F1 or Brn3A) immunofluorescence staining was used to detect retinal ganglion cell loss. Western blotting was performed to detect the expression levels of SARM1 and SNPH in the rat retina and optic nerve. Immunofluorescence staining was used to examine their distribution in these tissues. Furthermore, CRISPR/Cas9 technology was used to knock down the expression of SARM1 and SNPH in mouse 661W retinal ganglion cells, respectively. Cells were collected 48 hours after transfection, and Western blotting was performed to detect the expression levels of SARM1 and SNPH. Normally distributed continuous data are presented as mean\u00b1SEM. Comparisons between two groups were performed using the Student's t-test, while comparisons among multiple groups were assessed by the one-way analysis of variance followed by the Tukey's multiple comparisons test. Results: Western blot analysis revealed that in the glaucoma model group, the relative expression level of SARM1 protein in the optic nerve at one week post-modeling (1.22\u00b10.06) was significantly higher than that in the control group (1.03\u00b10.01; P=0.027, q=4.38). In contrast, the expression level of SARM1 in the retina at three days post-modeling (0.79\u00b10.02) was significantly lower than that in the control group (1.04\u00b10.03; P<0.001, q=6.86). Concurrently, the expression level of SNPH at three days post-modeling (0.74\u00b10.01) was lower than that in the control group (1.03\u00b10.04; P=0.040, q=0.58), and its expression at one week post-modeling (1.19\u00b10.10; P=0.002, q=4.36) was significantly higher than that at three days (0.74\u00b10.01). Consistent with the Western blot results, immunofluorescence staining results showed that in the optic nerve of the glaucoma model group, the expression of SARM1 was significantly higher than that in the control group at one week post-modeling, while the expression of SNPH was lower than that in the control group at three days post-modeling. Both proteins partially co-localized with the neuronal marker \u03b23-tubulin. Immunofluorescence staining also revealed co-localization of these two proteins within axons. Additionally, SARM1 co-localized with the mitochondrial marker protein TOM20. Western blot results from 661W cells showed that the knockdown of SARM1 expression (0.54\u00b10.04) significantly reduced SNPH expression (0.54\u00b10.05; P=0.003, q=7.98), whereas the knockdown of SNPH expression (0.39\u00b10.06) did not markedly affect SARM1 levels (0.75\u00b10.05; P=0.010, q=6.39). Conclusion: The elevated expression of SARM1 protein in the axons of the rat glaucoma model can promote retinal ganglion cell axonal pathology by localizing to axonal mitochondria and regulating SNPH expression. \u76ee\u7684\uff1a

42379864\nTitle: [Construction of a regulated Crat overexpression system in mouse hippocampal neuronal HT22 cell line].\nAbstract: Objective: To construct an inducible carnitine acetyltransferase (Crat) gene expression system and provide a controllable experimental platform for research on neuroprotection in glaucoma. Methods: This experimental study was conducted from January 2025 to November 2025 using the mouse hippocampal neuronal HT22 cell line. A high-efficiency tetracycline-inducible lentiviral gene expression system was established by optimizing the multiplicity of infection (MOI) and polybrene concentration, as well as comparing the activities of the cytomegalovirus (CMV) promoter and the elongation factor 1\u03b1 (EF1A) promoter. According to promoter type, the cells were divided into two groups: the CMV promoter group, in which enhanced green fluorescent protein (EGFP) fluorescence was detected, and the EF1A promoter group, in which mCherry fluorescence was detected. Conditional Crat overexpression was induced by doxycycline (Dox). Unmodified HT22 cells were assigned to an uninfected control group and an uninfected Dox-treated group, whereas successfully constructed HT22-TRE-mCrat/rtTA cells were assigned to an infected non-Dox-treated group and an infected Dox-treated group. The neuroprotective effect of the Crat overexpression system was evaluated in an H2O2-induced oxidative injury model by measuring lactate dehydrogenase (LDH) release, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining, and the mRNA expression levels of apoptosis-related factors, including caspase-3, B-cell lymphoma 2-associated X protein (Bax), and B-cell lymphoma 2 (Bcl-2), using quantitative PCR (qPCR). Statistical analyses were performed using the independent-samples t-test or one-way analysis of variance, with Tukey's test for pairwise comparisons. Results: A tetracyline-inducible gene expression system was successfully constructed and stably established in HT22 cells. The EF1A promoter showed higher driving efficiency than the CMV promoter, with a significantly greater number of positive cells in the EF1A promoter group than in the CMV promoter group [(303.0\u00b128.0) vs. (88.7\u00b111.4) cells; t=17.37, P<0.001]. In the H\u2082O\u2082-induced oxidative injury model, the LDH release rate was significantly lower in the infected Dox-treated group than in the uninfected Dox-treated group (27.1%\u00b14.7% vs. 49.8%\u00b18.2%; P<0.001). The apoptotic cell rate determined by TUNEL staining was significantly lower in the infected Dox-treated group than in the uninfected Dox-treated group (14.1%\u00b13.4% vs. 41.3%\u00b14.1%; t=16.23, P<0.001). The caspase-3 mRNA level was significantly lower in the infected Dox-treated group than in the uninfected Dox-treated group (140.3\u00b117.1 vs. 192.0\u00b124.3; t=4.26, P=0.002). Bax mRNA expression was significantly lower in the infected Dox-treated group than in the uninfected Dox-treated group (132.0\u00b113.1 vs. 169.8\u00b112.6; t=5.09, P<0.001). Bcl-2 mRNA expression was significantly higher in the infected Dox-treated group than in the uninfected Dox-treated group (83.2\u00b16.9 vs. 58.3\u00b18.1; t=5.74, P<0.001). All of these differences were statistically significant.

Whether this expansion represents a coherent transition toward smart, manufacturable, and function-oriented tissue-engineering systems remains unclear. We conducted an AI-assisted, rule-guided, and manually audited evidence architecture reconstruction of glaucoma-related biomaterial studies published from 2006 to 2025. Records from Web of Science Core Collection, Scopus, and PubMed were integrated, deduplicated, parsed from RIS files, screened, and quality controlled. Retained studies were classified by application scenario, evidence level, and translational features. Core evidence records were assigned to five operational levels, from material preparation and physicochemical characterization to disease-microenvironment intervention, long-term functional integration, and clinical or advanced translational evidence. Theme maturity and the convergence of smart material, additive manufacturing, and tissue-engineering relevance were further assessed. From 1,227 parsed records, 596 were retained, including 547 core evidence studies and 49 review or background records. In the core evidence set, Level 1 to Level 5 evidence included 93, 57, 140, 99, and 158 records, respectively. Level 1-3 evidence accounted for 53.0% of the core evidence set, whereas Level 4-5 evidence accounted for 47.0%, indicating a substantial but unevenly distributed translational component. In situ hydrogels and contact lens-based delivery systems represented the largest application categories, whereas retinal ganglion cell protection, trabecular meshwork modeling, anti-fibrosis after glaucoma surgery, GDD/MIGS-related interfaces, and 3D printing represented smaller but more disease-specific or integration-oriented domains. Glaucoma-related biomaterials are moving beyond passive delivery platforms, but their transition toward smart materials, additive manufacturing, and functional tissue engineering remains uneven. Future studies should emphasize reproducible material design, disease-relevant functional endpoints, outflow-pathway models, neuroprotection, and engineered surgical interfaces.\n\nID: 42364138\nTitle: Agreement between ganglion cell-inner plexiform layer metrics from widefield optical coherence tomography and Goldmann II, III, and V in glaucoma.\nAbstract: To compare concordance between ganglion cell-inner plexiform layer metrics acquired using widefield optical coherence tomography (OCT) and visual function assessed using Goldmann (G) II, III, and V stimulus sizes, in turn evaluating the role of spatial summation properties in binary classification of visual field (VF) results. Eighty three glaucoma and 34 healthy participants underwent widefield OCT scans, segmented to generate ganglion cell-inner plexiform layer measurements, and 24-2 VF assessment using GII, GIII, and GV in full threshold mode. Accuracy was assessed using mean weighted absolute error and 95% prediction interval width from mixed effects models between ganglion cells per stimulus area estimated from ganglion cell-inner plexiform layer thicknesses and VF thresholds compared using mixed effects models and post hoc analyses of estimated marginal means. Across healthy and glaucoma eyes, mean weighted absolute error and 95% prediction interval widths were smallest with GV (p\u00a0<\u00a00.0001), suggesting the least model variability with GV. With VF locations in glaucoma cohort subclassified into VF nondefective and VF defective, although significant differences in mean weighted absolute error and 95% prediction interval widths were noted within stimulus sizes (p\u00a0<\u00a00.0001), larger values indicating poorer model accuracy were noted in glaucoma VF defective locations relative to both healthy and VF nondefective models. Larger mean weighted absolute errors and 95% prediction interval widths were observed with increasing disease stage in VF defective locations across all stimulus sizes (p\u00a0<\u00a00.0001). Overall, structure-function models in healthy eyes and VF nondefective locations were similar across all stimulus sizes, but larger deviations were observed in VF defective locations and with worsening glaucoma stage. Our findings suggest that GIII sufficiently balances measurement variability and VF defect detection, but that disease stage-specific variations in the structure-function relationship exist and the ability to monitor VF defect progression over time is poor regardless of stimulus size.\n\nID: 42363190\nTitle: Mechanochemically primed regenerative extracellular vesicles as a nanotherapeutic strategy for peripheral neuropathy.\nAbstract: Peripheral neuropathy is a chronic neurological disorder characterized by inflammation, nerve damage, and impaired function. It arises owing to various factors, including traumatic nerve injury, neuropathic pain due to cancer, and diabetic neuropathy. Although conventional two-dimensional culture-based mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) demonstrate therapeutic potential for neuropathy, their regenerative efficacy and consistency are limited. Therefore, the present study proposes a nanobiology-based therapeutic strategy for neuroregenerative medicine. In this study, MSCs were preconditioned using transforming growth factor beta-3 and cultured in a three-dimensional dynamic culture system to produce highly functional mechanochemically primed regenerative EVs (MCR-EVs). In an ex vivo organotypic spinal cord slice injury model with demyelination, MCR-EVs were internalized by slice-resident cells and significantly attenuated cell death compared to conventional 2D-EVs (Con-EVs). MCR-EVs also promoted the recovery of axonal integrity and pro-survival signaling in injured spinal cord slices, as indicated by increased neurofilament-M immunoreactivity, restored protein kinase B phosphorylation, and growth-associated protein 43 expression. MCR-EVs exhibited enhanced therapeutic effects compared with Con-EVs in a mouse model of peripheral neuropathy induced by chronic constriction injury. The MCR-EV-treated group exhibited downregulated expression of proinflammatory genes, including tumor necrosis factor-\u03b1, interleukin-1\u03b2, interleukin-6, and cyclooxygenase-2, accompanied by inhibition of microglial activation and cell death. Additionally, the axonal structure was restored, as demonstrated by increased expression of neurofilament heavy chain, neuron-specific class III \u03b2-tubulin, and neuronal nitric oxide synthase. The MCR-EV-treated group also exhibited increased expression of Schwann cell-related markers (S100\u03b2, myelin basic protein, and myelin-associated glycoprotein), maintenance of neuromuscular structure, and upregulated platelet endothelial cell adhesion molecule 1 expression levels. Moreover, in MCR-EVs, small RNA sequencing confirmed the presence of several miRNAs that are potentially associated with nerve regeneration, inflammation, and pain modulation. These results suggest that MCR-EVs contribute to the recovery of myelinated axons and regeneration of peripheral tissues, thus protecting endothelial cell components. MCR-EVs improved therapeutic outcomes compared to current Con-EV treatments and may promote peripheral neuropathic recovery by modulating anti-inflammatory and nerve regeneration pathways.\n\nID: 42358370\nTitle: Correction: The potential of Lisosan G as a possible treatment for glaucoma.\nAbstract: [This corrects the article DOI: 10.3389/fphar.2021.719951.].\n\nID: 42356426\nTitle: Neuroprotective Indole Diterpenoids from the Fungus Tolypocladium album DWS131.\nAbstract: Context/Objective: Fungi of the genus Tolypocladium are known for their diverse metabolic capabilities and medicinal potential. Indole diterpenoids (IDTs) represent a structurally unique class of fungal metabolites. Beyond their established roles as mycotoxins, these compounds have recently shown promise for neuroprotective effects. The objective of this study was to isolate and characterize novel IDTs from Tolypocladium album DWS131 and evaluate their neuroprotective activities and underlying mechanisms. Methods: IDTs were isolated through comprehensive chromatographic techniques. Their structures were elucidated using HRESIMS data, 1D/2D NMR spectra, and quantum chemical calculations. Neuroprotective effects were evaluated using glutamate (Glu)-induced R28 cells in vitro and N-methyl-D-aspartic acid-induced mouse models in vivo. A total of 48 mice were utilized for in vivo evaluations, divided into two separate experimental cohorts. In each cohort, mice were randomly assigned to four groups (n = 6 per group). Post-intravitreal injection, retinal survival and visual function were assessed via Brn3a-stained flat-mounts, H&E staining, f-VEP, f-ERG, and OptoDrum. Mechanisms involving the SLC7A11/GPX4/ACSL4 axis were investigated by Western blotting and immunofluorescence. Results: Seven previously undescribed paxilline-type IDTs, tolypindoles A-G (1-7), and two known analogues (8-9) were identified. Compounds 8 and 9 exhibited significant neuroprotection closely associated with the attenuation of oxidative stress and the modulation of ferroptosis-related pathways in Glu-induced R28 cells. In vivo, they preserved retinal ganglion cells, maintained retinal structure, and protected visual function, with compound 8 demonstrating superior efficacy. Mechanistic investigations revealed that both compounds modulate the SLC7A11/GPX4/ACSL4 signaling axis. Conclusions: This study expands the chemical diversity of T. album DWS131. Compounds 8 and 9, characterized by isopentenyl moieties, highlight a promising therapeutic potential for retinal neurodegenerative diseases such as glaucoma.\n\nID: 42353267\nTitle: Neuroprotection in Early Diabetic Retinal Disease Using Eyedrop Delivery.\nAbstract: Diabetic retinal disease (DRD) has classically been defined as a microvascular complication of diabetes; however, the recent evidence highlighted the key role of neuronal degeneration during the earliest stages of its pathogenesis. Therefore, neuroprotection has emerged as a promising therapeutic strategy to prevent disease progression. Topical administration via eyedrops represents a non-invasive approach to deliver neuroprotective agents directly to the retina. This review summarizes the current advances in the field of neuroprotective therapies against early DRD with a special focus on topical delivery, including preclinical and clinical evidence, while discussing the relevance of the transscleral route of absorption in all of them. In this review, the most promising neuroprotective compounds under development will be discussed, highlighting the opportunity that they represent for treating early stages of DRD.\n\nID: 42352347\nTitle: L-Serine Attenuates Metabolic and Behavioural Features of Diabetic Neuropathy with Dose-Dependent Central Proteomic Correlates in a Rat Model.\nAbstract: Diabetic neuropathy (DN) is a multifactorial complication of diabetes mellitus driven by chronic hyperglycemia, insulin resistance, and disturbed metabolic homeostasis, leading to progressive injury of both the peripheral and central nervous systems. This study investigated whether L-serine supplementation could attenuate DN through dose-dependent metabolic and neuroprotective mechanisms in a high-fat diet (HFD) plus streptozotocin (STZ)-induced diabetic rat model. Male Wistar rats (n = 8 per group) were allocated to five groups: normal control (NC), diabetic control (DC), pioglitazone (PIO; 1.5 mg/kg/day), low-dose L-serine (S1; 200 mg/kg/day), and high-dose L-serine (S2; 400 mg/kg/day). After 60 days of oral gavage, behavioural testing, glucose and insulin profiling, HOMA-IR calculation, brain histopathology, nerve growth factor (NGF) immunohistochemistry, and LC-MS/MS-based proteomic analysis of cerebral tissue were performed. Diabetic rats exhibited marked hyperglycaemia (355.33 \u00b1 4.72 mg/dL), hyperinsulinaemia, severe insulin resistance (HOMA-IR 16.8 \u00b1 3.2; a 14-fold increase), impaired thermal nociception, motor dysfunction, and pronounced neuronal degeneration. L-serine supplementation significantly improved metabolic status: S1 reduced HOMA-IR by 77.4% and S2 by 87.5% relative to diabetic controls (p < 0.001). High-dose L-serine produced greater improvements in thermal sensitivity, motor coordination (rotarod latency 26.67 \u00b1 1.52 s vs. 16.1 \u00b1 0.85 s in DC; p < 0.05), and NGF expression (8.6-fold increase vs. DC). Histopathology confirmed attenuation of neuronal injury and gliosis in both treatment groups. Exploratory, group-level proteomic profiling identified dose-specific molecular signatures: S1 was predominantly associated with carbohydrate, lipid, and biosynthetic pathways, whereas S2 was associated with synaptic, neurotransmission-related, and proteostasis pathways. Within the constraints of an exploratory design-group-level pooled proteomics, analysis of cerebral rather than peripheral-nerve tissue, and only two doses-these findings indicate that L-serine attenuates the metabolic and behavioural features of experimental diabetic neuropathy and generates the testable hypothesis of dose-dependent neuro-metabolic remodelling. The proteomic signatures are hypothesis-generating and require orthogonal validation before any mechanistic or translational inference can be drawn.\n\nID: 42343315\nTitle: Diagnostic capability of ganglion cell complex thickness using spectral domain optical coherence tomography in glaucoma.\nAbstract: This study had two main aims: first, aimed to document the normal values of macular ganglion cell complex (GCC) thickness among control eyes and glaucoma suspects and second, to evaluate the diagnostic ability of GCC parameters in distinguishing Primary Open Angle Glaucoma (POAG), Glaucoma Suspects and Controls in a tertiary eye centre in Nepal. A hospital-based cross-sectional observational study was conducted in Kathmandu, Nepal, from June 2020 to June 2021. GCC parameters (Average GCC, Superior GCC, and Inferior GCC) were measured using spectral-domain Optical Coherence Tomography (OCT). These parameters were compared among groups using Linear Mixed-effect Models, considering considerable inter-eye correlation. Receiver operating characteristic (ROC) curves were constructed, and area under the curve (AUC) values were calculated to assess diagnostic performance. A total of 203 patients (406 eyes) were included\u2009-\u200976 with POAG, 62 Glaucoma suspects, and 65 Controls. Average GCC, superior GCC and Inferior GCC thickness were 96.54\u2009\u00b1\u200910.09\u00a0\u03bcm, 96.68\u2009\u00b1\u200910.91\u00a0\u03bcm and 96.43\u2009\u00b1\u20099.60\u00a0\u03bcm, in controls; 83.30\u2009\u00b1\u200911.46\u00a0\u03bcm, 83.88\u2009\u00b1\u200912.29\u00a0\u03bcm, and 81.94\u2009\u00b1\u200913.19\u00a0\u03bcm in POAG, and 93.76\u2009\u00b1\u20097.74\u00a0\u03bcm, 94.02\u2009\u00b1\u20098.03\u00a0\u03bcm, and 93.82\u2009\u00b1\u20098.27\u00a0\u03bcm, respectively in glaucoma suspects. All GCC parameters were significantly lower in the POAG group compared with both glaucoma suspects and controls (p\u2009<\u20090.05), even after adjustment for age. The highest diagnostic accuracy was observed for average GCC (AUC\u2009=\u20090.83, 95% C.I. - 0.77-0.92) and inferior GCC (AUC\u2009=\u20090.83, 95% C.I. - 0.76-0.90), both demonstrating excellent discrimination between POAG and controls (AUC\u2009=\u20090.83). All GCC parameters demonstrated a significant diagnostic capability in detecting POAG, with average GCC and inferior GCC thickness showing the best performance. The single-centre cross-sectional study design, and lack of randomisation were the main limitations of this study.\n\nID: 42337179\nTitle: Improvement of pattern electroretinogram parameters following glaucoma surgery.\nAbstract: To assess the dynamics of Pattern Electroretinogram (PERG) parameters following glaucoma surgery in individuals with glaucomatous optic neuropathy. The is a single center retrospective study. Preoperative PERG were conducted on moderate and advanced glaucoma patients scheduled for glaucoma surgery. Subsequently, the patients underwent an additional PERG a few months after the procedure. Comparative analysis focused on the PERG parameters (Mag, MagD and MagD/Mag ratio) before and after the glaucoma surgery in eyes achieving successful intraocular pressure (IOP) reduction post-operatively. The study enrolled 23 eyes from 21 consecutive patients who underwent successful glaucoma surgery between January 2021 and December 2023, each with both pre and post-operative PERG assessments. Postoperatively, there was a significant improvement of all the PERG parameters (0.97\u2009\u00b1\u20090.29 to 1.36\u2009\u00b1\u20090.29\u00a0\u03bcV, 0.55\u2009\u00b1\u20090.3 to 0.84\u2009\u00b1\u20090.42\u00a0\u03bcV, 0.52\u2009\u00b1\u20090.2 to 0.68\u2009\u00b1\u20090.25 for Mag, MagD and MagD/Mag ratio respectively, all p\u2009<\u20090.05). Three patients who had no IOP reduction postoperatively showed no improvement of all PERG parameters following the surgery. Glaucoma surgery, leading to effective IOP reduction, may demonstrate a positive impact on the functional activity of the retinal ganglion cells, as evidenced by the enhancement in PERG parameters post-operatively.\n\nID: 42333387\nTitle: Prospects for Neuroprotective Therapies in Glaucoma: Drug Targets and Emerging Clinical Strategies.\nAbstract: Management of glaucoma is now at an inflection point with a new generation of therapeutic candidates, whilst targeting intraocular pressure-independent strategies is challenged by the landmark Phase III failure of memantine regarding trial design and endpoint sensitivity. Preclinical research has identified promising targets including glutamate excitotoxicity, neurotrophic factor deprivation, and mitochondrial dysfunction, with nicotinamide emerging as a leading candidate due to its ability to robustly protect RGCs by supporting NAD levels and bioenergetics. Current clinical efforts are expanding into metabolic repurposing with agents (eg metformin and semaglutide), sustained-delivery systems with neurotrophic factors (eg ciliary neurotrophic factor implant), and functional enhancers (eg citicoline). To bridge the translational gap, the field is integrating new endpoints with higher sensitivity (eg advanced assessment of photopic negative response), AI-guided endpoint selection (eg graph attention neural network), novel biomarkers (eg detection of apoptotic retinal cells and neurofilament light chain in aqueous humor), and precision medicine frameworks (eg polygenic risk scores and multi-omics analysis) to develop the first clinically validated neuroprotective treatments for glaucoma.\n\nID: 42321202\nTitle: Interdependent roles of PKM2 in photoreceptors and RPE: implications for retinal degeneration.\nAbstract: Pyruvate kinase M2 (PKM2) functions as both a glycolytic enzyme and a transcriptional co-activator that coordinates metabolism and cell survival. Here, we define the developmental timing, cellular distribution, and physiological role of PKM isoforms in the mouse retina. PKM2 expression begins at postnatal day 2, preceding PKM1, and is highly enriched in photoreceptors, whereas PKM1 predominates in retinal ganglion cells. Conditional deletion of PKM2 in the retina, rods, or retinal pigment epithelium (RPE) demonstrated that PKM2 is essential for maintaining retinal structure and function. Loss of PKM2 impaired glycolytic activity, decreased ATP generation, and disrupted metabolic balance, leading to cellular disorganization and degeneration in both photoreceptors and the RPE. In the RPE, PKM2 deficiency decreased RPE65 protein levels and impaired the regeneration of 11-cis-retinal, disrupting the visual cycle. PKM2 deletion disrupted the normal cone opsin gradient, indicating that PKM2-dependent metabolic and transcriptional functions are essential for maintaining proper cone organization in the retina. Moreover, rod-specific deletion of PKM2 in Abca4 mutant mice showed early signs of retinal degeneration. The studies described in this manuscript highlight the interdependence of photoreceptor and RPE metabolism and show that PKM2 plays an important role in retinal energy homeostasis and neuronal survival, providing insight into the mechanisms underlying photoreceptor and RPE degeneration in age-related macular degeneration.\n\nID: 42304965\nTitle: Differential Effects of Calcium Alginate and Carboxymethylcellulose Wound Dressing Extracts on Human Sensory Neuron Regeneration and Secretome.\nAbstract: The peripheral nervous system is critical for wound healing, with sensory nerves releasing neuropeptides that drive tissue repair. Sensory nerve damage impairs healing and contributes to chronic wounds, as observed in diabetic neuropathy. However, the impact of advanced wound dressings on peripheral nerves remains unexplored. Identifying dressings that favour nerve regeneration would aid in managing complex wounds. This study explores the in\u00a0vitro effects of three wound dressings on sensory neurons: a pure calcium alginate dressing (Alginate), a mixed calcium alginate combined with carboxymethylcellulose dressing and a pure carboxymethylcellulose (CMC) dressing. Sensory neurons from neural progenitors were exposed to dressing extracts for 5\u2009days. Cell viability, neurite regeneration after axotomy and neurite outgrowth from neurospheres were assessed. Neurite extension was evaluated in compartmentalised chips where extracts were restricted to the neurite compartment. Only Alginate was non-cytotoxic across tested concentrations. In the axotomy model, Alginate and CMC preserved neurite regeneration, whereas the mixed dressing impaired regeneration. In neurospheres, Alginate significantly enhanced neurite outgrowth, while CMC had no effect and the mixed dressing inhibited outgrowth. Additionally, Alginate upregulated the secretion of neurotrophic and pro-repair factors, including brain-derived neurotrophic factor and vascular endothelial growth factor, whereas CMC and the mixed dressing mostly down-regulated key factors. Finally, in compartmentalised culture, Alginate tended to enhance neurite extension, while CMC preserved it and the mixed dressing led to regression. These findings suggest that pure calcium alginate dressing supports nerve repair, essential for healing neuropathic wounds and may explain its good clinical performance in complex wounds.\n\nID: 42285746\nTitle: Association of Aqueous Humor Tumor Necrosis Factor Alpha with Retinal Ganglion Cell Thickness in Juvenile versus Adult-Onset Primary Open-Angle Glaucoma.\nAbstract: To evaluate the association between aqueous humor tumor necrosis factor alpha (TNF-\u03b1) and retinal ganglion cell (RGC) layer in patients with juvenile open-angle glaucoma (JOAG) and their comparison with adult-onset primary open-angle glaucoma patients (POAG). This analytical cross-sectional study included 15 JOAG patients (aged 7-40 years) and 15 POAG patients (&gt; 40 years). Aqueous Humor (AH) samples were collected during trabeculectomy, TNF-\u03b1 concentrations were measured using ELISA, and RGC thickness was assessed by Optical Coherence Tomography (Cirrus HD-OCT, Carl Zeiss). Group differences were analyzed using the independent t-test, and correlations were evaluated with Pearson's\u00a0test. The mean AH TNF-\u03b1 level in the JOAG group (179.02 \u00b127.04 pg/mL) was significantly higher than in the POAG group (130.17 \u00b118.62 pg/mL; p.\n\nID: 42282664\nTitle: Inhibition of Soluble Epoxide Hydrolase Rescues Cognitive Deficits by Preserving Neurovascular Integrity and Attenuating Glial- and Neuropathology in Diabetic-Related Dementia.\nAbstract: Diabetes mellitus (DM) is a major risk factor contributing to the development of Alzheimer's disease-related dementias (ADRD). While one of the early symptoms of both Alzheimer's disease (AD) and DM-related ADRD is a reduction in cerebral blood flow, the underlying biological mechanisms driving this decline remain to be fully elucidated. Genome-wide association studies have linked AD/ADRD to single-nucleotide polymorphisms in the gene encoding soluble epoxide hydrolase (sEH), an enzyme we previously reported to be upregulated in the brains of an AD rat model. Our previous work also demonstrated that chronic inhibition of sEH with 1-trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl) urea (TPPU) preserves hippocampal-dependent spatial learning and memory and improves cerebral hemodynamics in both AD and DM-ADRD models. In the present study, we found that chronic TPPU treatment (1 mg/kg/day for 9 weeks) reduced brain sEH expression, improved cortical-based long-term non-spatial recognition memory involving both cortical and hippocampal networks, and reduced anxiety in DM-ADRD rats. TPPU improved brain perfusion and normalized impaired whisker-evoked functional hyperemia, an effect linked to upregulation of Kir2.1 expression in cerebral capillaries. Furthermore, TPPU restored tight junction proteins (ZO-1 and OCLN), mitigated capillary rarefaction, and suppressed astrocyte and microglial activation. At the cellular level, TPPU attenuated hippocampal neurodegeneration, restored the expression of synaptic proteins (PSD95 and SY38), and reduced levels of key pro-inflammatory chemokines, including MCP-1, RANTES, and MIP-1\u03b1, in DM-ADRD. In conclusion, TPPU preserves cognitive function in DM-ADRD by mitigating cerebrovascular dysfunction, neuroinflammation, and gliosis while protecting synaptic integrity and neuronal survival, representing a promising therapeutic strategy for DM-ADRD.\n\nID: 42448725\nTitle: Study on the application effect of intelligent follow-up based on KPAI theory in patients with diabetic retinopathy.\nAbstract: With the continuous increase in the global prevalence of diabetes, the prevention and treatment of diabetic retinopathy (DR) have become a global public health challenge. In China, due to population aging, lifestyle changes, and advances in medical diagnostic technology, the incidence and detection rate of DR have been increasing year by year. Therefore, exploring effective management and follow-up models for DR is of paramount importance in reducing the blindness rate caused by DR and improving the quality of life of patients. Based on the KPAI theory, a questionnaire for postoperative follow-up needs of patients with diabetic retinopathy was developed to determine the effectiveness of the questionnaire. The content of intelligent follow-up was adjusted based on the results of the needs questionnaire survey, and the changes in disease knowledge, physical, psychological, and social aspects of postoperative follow-up patients were evaluated. A total of 1372 patients with diabetic retinopathy who received treatment in our hospital's wards from January 2023 to December 2023 were selected. Among them, 278 patients underwent a postoperative follow-up needs survey, with 347 patients undergoing routine follow-up and 445 patients undergoing intelligent follow-up, with a follow-up time of one week after surgery. In the first participation of patients in intelligent follow-up, 20 patients were randomly selected for follow-up one month and three months after surgery to assess changes in patient indicators. The scale finally determined 16 items, including information acquisition, postoperative self-management, psychological emotions, and social integration, with a Cronbach's \u03b1 coefficient of 0.662, I-CVI range of 0.714 to 1, and an S-CVI value of 0.929. After routine follow-up and intelligent follow-up, negative social emotions, public health positive index, and scores of depression-anxiety-stress were statistically significant (P\u2009<\u20090.05). The boxplots after intelligent follow-up in the first week, one month, and three months all showed an improving trend. The questionnaire for postoperative follow-up needs of patients with diabetic retinopathy based on KPAI has clinical utility. The use of an intelligent follow-up system is beneficial to the postoperative recovery of patients with diabetic retinopathy and improves the physical and mental health of patients.\n\nID: 42446486\nTitle: Engineering an injectable and tunable hydrogel as a potential vitreous substitute.\nAbstract: Retinal detachment, proliferative diabetic retinopathy, and ocular trauma are major causes of blindness, and their treatment often relies on intraocular endotamponades following vitrectomy. However, many existing endotamponades tend to disperse or fragment during injection, making it difficult to form a stable structure within the vitreous cavity and thereby severely limiting their functional performance and clinical applicability. Consequently, the development of injectable endotamponades with controlled viscosity and in situ gelation remains a critical challenge. In this study, we present an injectable polyethylene glycol (PEG) hydrogel incorporating high-molecular-weight hyaluronic acid (HA), designed to mimic key physicochemical features of the human vitreous. The hydrogel forms a three-dimensional network via covalent crosslinking between eight-arm PEG-thiol (8sPEG-SH) and eight-arm PEG-maleimide (8sPEG-MAL), while incorporating high-molecular-weight HA enables viscosity regulation and imparts vitreous-like mechanical properties. The hydrogel exhibits a storage modulus of 15 Pa and an adjustable in situ gelation time of approximately 3 minutes, together with good optical transparency, appropriate surface tension, and a low swelling ratio. In vivo studies in rabbit eyes further demonstrate that the hydrogel can be smoothly injected and subsequently form a stable structure within the vitreous cavity, confirming its practical operability for intraocular application. This work introduces a tunable PEG hydrogel system with controllable in situ gelation via a double-chamber syringe, offering a new strategy for preliminary evaluation of vitreous substitutes with favorable intraocular biocompatibility.\n\nID: 42434121\nTitle: Nanomaterial-enabled delivery of plant-derived bioactive metabolites for diabetic retinopathy: from evidence appraisal to preclinical translation.\nAbstract: As a leading cause of preventable blindness globally, diabetic retinopathy (DR) requires innovative treatments beyond conventional anti-VEGF therapies, which face limitations in efficacy, administration burden, and multifactorial targeting. Plant-derived bioactive metabolites (e.g., quercetin, puerarin) have been reported to modulate multiple DR-relevant pathways in preclinical studies against DR pathogenesis, including modulation of angiogenesis, oxidative stress, and inflammation. However, their clinical translation is hindered by compound- and route-dependent pharmacokinetic challenges, including poor solubility, extensive metabolism, rapid ocular clearance, and restricted posterior-segment exposure. This review explores nanomaterial-enabled delivery systems to overcome these barriers, detailing platforms such as polymeric nanoparticles, lipid-based carriers, and exosomes engineered to enhance solubility, penetration, and sustained release. Key strategies including barrier-specific size optimization, surface engineering, and ligand functionalization are critically analyzed. Integrated preclinical frameworks utilizing in vitro models and in vivo rodent studies, along with pharmacokinetic and safety evaluations, are emphasized. Finally, regulatory considerations and clinical trial challenges are addressed. Nanomaterial-mediated delivery represents a paradigm shift and may provide a promising translational strategy for plant-derived bioactive metabolites in DR, but its clinical relevance will depend on rigorous ocular pharmacokinetic, efficacy, safety, manufacturing, and regulatory validation.\n\nID: 42422117\nTitle: The burden of diabetic retinopathy-related blindness and visual impairment in the global labor force from 1990 to 2021 and projections to 2050: Analysis based on the 2021 global burden of disease study.\nAbstract: Diabetic retinopathy (DR) is a major microvascular complication of diabetes and is the leading cause of blindness and visual impairment among working-age populations worldwide. The loss of vision caused by diabetes significantly reduces the quality of life and has a major impact on the overall burden of visual impairment. This study assessed the global burden of blindness and visual impairment caused by diabetes among the working population from 1990 to 2021, and predicted the future trends in 2050. Based on data from the Global Burden of Disease Study 2021, we analyzed trends from 1990 to 2021 in the burden of diabetes-related blindness and visual impairment. Key metrics included case numbers and rates of prevalence and years lived with disability (YLDs). Decomposition analysis identified drivers of burden changes, and health inequality analysis assessed disparities by socioeconomic status. We used ARIMA and exponential smoothing models to forecast prevalence and YLDs from 2022 to 2050. From 1990 to 2021, the global burden of blindness and visual impairment caused by diabetes among the working population significantly increased.From 1990 to 2021, the global burden of blindness and visual impairment caused by diabetes among the working population significantly increased. Comparative analysis shows that the number of cases of type 2 diabetes and the number of YLDs are much higher than those of type 1 diabetes. Moreover, the burden on women has always been higher than that on men. Among the working population, blindness and visual impairments caused by diabetes pose a serious and increasingly severe public health threat worldwide, with the impact on women being particularly significant.Among the working population, blindness and visual impairments caused by diabetes pose a serious and increasingly severe public health threat worldwide, with the impact on women being particularly significant. Therefore, urgent action is needed to raise awareness of diabetic retinopathy among both clinicians and the general public, improve the level of early detection and treatment, reduce preventable vision loss, and alleviate the impact on family life and social economic burden caused by this decline in quality of life. Therefore, urgent action is needed to raise awareness of diabetic retinopathy among both clinicians and the general public, improve the level of early detection and treatment, reduce preventable vision loss, and alleviate the impact on family life and social economic burden resulting from this decline in quality of life.\n\nID: 42415853\nTitle: Current Landscape and Future Perspectives of Diabetic Retinopathy Therapy: Pharmacological Targets, Precision Laser Technology, and Clinical Evidence.\nAbstract: Diabetic retinopathy (DR), a major cause of blindness worldwide, poses a substantial and escalating burden on public health. The limitations of current therapeutic modalities highlight the pressing need for continued innovation in therapeutic interventions. This review comprehensively delineated the knowledge architecture, research focal points, and emerging directions in DR therapeutics. Targeted biological agents have recently emerged as principal research directions in DR therapy and hold substantial promise. They are expected to achieve the goals of blocking disease progression more persistently, effectively, and less invasively than nonbiological therapeutics through multitarget synergy and long-acting sustained-release formulations. In clinical practice, the paradigm of DR therapy has shifted toward personalized and precision medicine, with optimized subthreshold micropulse laser as a promising adjunctive therapy for enhancing long-term treatment outcomes. Looking ahead, therapeutic monitoring in DR may evolve beyond conventional morphological grading to incorporate multimodal precision diagnostics, artificial intelligence-driven broad-spectrum screening, and biomarker-based early warning systems. This review concludes with a discussion on prospects and challenges in DR therapeutics, with special emphasis on emerging drug candidates, recent clinical trial findings, and novel insights that may inform the next generation of therapeutic interventions for DR.\n\nID: 42409919\nTitle: The linear association between estimated glomerular filtration rate and diabetic retinopathy: a cross-sectional study.\nAbstract: Diabetic retinopathy (DR) is the predominant microvascular complication of diabetes and the main cause of preventable blindness in working-age adults. Because the retina and kidney share similar microvascular architecture, renal dysfunction-routinely expressed as the estimated glomerular filtration rate (eGFR)-is biologically plausible as a marker of DR risk. However, the relationship between eGFR and DR remains controversial. This study aimed to investigate the association between eGFR and DR prevalence in diabetic patients with type 2 diabetes mellitus. This study represents a secondary analysis of data derived from a cross-sectional study. We included 2001 adults with diabetes mellitus (858 men and 1143 women; mean age 64.0\u2009\u00b1\u200911.3 years) who attended the internal-medicine outpatient clinics of two hospitals in southern Taiwan between April 2002 and November 2004. Demographic and clinical variables were recorded, and eGFR was calculated using the simplified MDRD equation. The association between eGFR and DR was examined with multivariable logistic regression, adjusting for potential confounders. To explore potential non-linear relationships, we further applied a generalized additive model (GAM) with smooth-spline fitting. Higher eGFR was inversely associated with the odds of DR across progressively adjusted models. When modeled as a continuous variable, higher eGFR was linked to lower DR odds in Model 1 (OR 0.88; 95% CI 0.83-0.92; P\u2009<\u20090.0001), Model 2 (OR 0.90; 95% CI 0.85-0.95; P\u2009<\u20090.0001), and remained significant after full adjustment in Model 3 (OR 0.92; 95% CI 0.87-0.98; P\u2009=\u20090.0056), indicating a robust inverse association. Compared with the lowest eGFR tertile (15.36-60.50 mL/min/1.73 m2), the highest tertile (76.68-141.22 mL/min/1.73 m2) showed a 30% lower risk of DR (adjusted OR 0.70, 95% CI 0.50-0.90). Smooth-spline analysis confirmed a linear inverse relationship, and no significant effect modification was observed across subgroups of age, sex, BMI, blood pressure, glycaemic control or cardiovascular comorbidities. This cross-sectional analysis demonstrates a clear dose-response pattern: each incremental increase in estimated glomerular filtration rate (eGFR) is associated with a proportional reduction in the likelihood of diabetic retinopathy among adults with type 2 diabetes mellitus. Future work should dissect the shared microvascular pathways linking the kidney and retina and determine whether interventions that preserve renal function can translate into meaningful reductions in retinopathy risk.\n\nID: 42405673\nTitle: The Molecular Basis of Ocular Aging: Mechanisms, Pathologies, and Emerging Therapeutics.\nAbstract: Age-related eye diseases (AREDs)-including age-related macular degeneration (AMD), glaucoma, and diabetic retinopathy-are leading causes of permanent blindness. Current treatments manage clinical manifestations but do not halt the molecular processes that drive disease progression. This limitation has shifted attention toward \"geroscience,\" a strategy that targets the fundamental biology of aging rather than treating each disease in isolation. Four key hallmarks of aging-mitochondrial dysfunction, loss of proteostasis, cellular senescence, and epigenetic drift-are widely implicated in AREDs. We review evidence that these hallmarks do not act independently; instead, they form an interactive, self-reinforcing network. The way this network engages differs from tissue to tissue. In the high-energy environment of the retinal pigment epithelium, mitochondrial dysfunction dominates and drives AMD. In the mechanically stressed trabecular meshwork (TM), senescence and epigenetic drift take precedence, leading to glaucoma. In the neurovascular unit, chronic hyperglycemia routes the same network into a metabolic-epigenetic amplification loop that sustains diabetic retinopathy. The same aging mechanisms, routed through distinct tissue contexts, thus produce divergent clinical phenotypes. We also evaluate emerging therapies, including senolytics, mitochondria-targeted agents, and partial epigenetic reprogramming, and identify key intervention nodes such as NLRP3, p62, and NAD\u207a metabolism. Dismantling these pathological feedback loops offers a path beyond symptom management toward combination strategies that restore tissue resilience.\n\nID: 42404883\nTitle: PANoptosis in diabetic retinopathy: immunological insights into mechanisms and translational therapies.\nAbstract: Diabetic retinopathy (DR), a leading cause of blindness, is driven by hyperglycemia-induced neurovascular damage. Emerging evidence indicates that PANoptosis, an integrated inflammatory programmed cell death modality encompassing apoptosis, pyroptosis, and necroptosis, participates in the progression of diabetic retinal damage; however, the supporting evidence varies substantially across clinical specimens, diabetic animal models, high-glucose cultured retinal cells, and non-DR inflammatory disease models. This review systematically summarizes the latest advances in PANoptosis-associated mechanisms underlying DR pathogenesis, focusing on PANoptosome signaling networks, non-coding RNA-mediated regulation, and immune-metabolic crosstalk. We outline promising candidate biomarkers including PANoptosis-related gene signatures and inflammatory cell death molecules, and critically evaluate multiple translational therapeutic strategies covering small-molecule inhibitors, gene intervention, and nanomedicine delivery. Importantly, we further address context-dependent dual roles of PANoptosis, potential safety risks of non-selective PANoptosis blockade, challenges in blood-retinal barrier penetration, systemic immune side effects, and pathological heterogeneity among DR subtypes and disease stages. Since PANoptosis also fundamentally contributes to host defense and retinal innate immune homeostasis, DR therapeutic strategies should prioritize biomarker-guided, local ocular delivery, time-dependent stage intervention, and cell-type-specific fine tuning, rather than generalized systemic suppression. By reconciling mechanistic progress with unresolved translational bottlenecks, this review proposes that PANoptosis serves as a dynamic and evolving conceptual framework for interpreting inflammatory neurovascular degeneration in DR, instead of an entirely confirmed clinical therapeutic target. We emphasize the urgent need for DR-specific mechanistic verification, longitudinal biomarker cohort studies, and well-designed multicenter clinical trials to advance safe and precise targeted interventions.\n\nID: 42404286\nTitle: Eye Health Among Islet Cell Transplant Recipients With Long-duration Type 1 Diabetes.\nAbstract: Diabetic retinopathy (DR) is the commonest cause of blindness among people with type 1 diabetes (T1D) and can progress over time. In Australia, islet cell transplantation (ICT) is available for adults with T1D experiencing recurrent severe hypoglycemia. Rapid improvement in glycemia, which can occur post-ICT, may lead to \"early worsening\" of DR and warrants investigation. This study explored eye health outcomes among ICT recipients. This retrospective study examined all ICT recipients at a single tertiary institution in Victoria, Australia, 2007-2022 inclusive. Recipients of successful ICT, with available eye health information pre- and posttransplantation, were included. Eye health outcomes were assessed relative to ICT for changes in DR and other major retinal pathologies. Sixteen recipients (30 eyes) with T1D duration median 31 y (interquartile range, 26-44) were followed up for 5 y (interquartile range, 4-9). At 12 mo post-ICT, hemoglobin A1c improved by -1.2 percentage points (-1.9 to -0.5; P\u2005<\u20050.001). Pre-ICT, 9 of 16 recipients (56%) had DR, with 4 recipients having proliferative DR. During follow-up post-ICT, 4 of 16 recipients (25%) had worsening eye outcomes; there were no new cases of proliferative DR. Four recipients had \"early worsening\" signs, not associated with progression of DR. Recipients experiencing worsening eye outcomes post-ICT exhibited higher hemoglobin A1c and lower C-peptide levels during 12 mo compared with recipients who had stable eye outcomes (P\u2005=\u20050.02 and P\u2005=\u20050.01, respectively). These findings highlight the potential positive impact of ICT to stabilize eye health among a small group of ICT recipients with long-duration type 1 diabetes. An extended systematic evaluation of eye health pre- and post-ICT is required to monitor both short-term and long-term eye health among transplant recipients.\n\nID: 42397510\nTitle: High glucose-induced mitochondrial fission promotes M\u00fcller cell activation via suppression of the Hippo pathway.\nAbstract: Diabetic retinopathy (DR) is the leading cause of blindness in diabetic patients, in which high glucose (HG)-induced M\u00fcller cell activation constitutes a central pathological event. This study aimed to untangle the critical role and mechanism of mitochondrial fission in this process. We found that under HG conditions, the level of p-Drp1 was significantly elevated (P\u2009<\u20090.05), driving excessive mitochondrial fission. Functional experiments confirmed that artificially enhancing mitochondrial fission directly inhibited the Hippo signaling pathway (levels of core proteins p-MST1/2, p-LATS1, and p-YAP decreased, P\u2009<\u20090.05, and YAP translocated to the nucleus), thereby activating M\u00fcller cells (expression of marker proteins GS and Kir4.1 decreased, while expression of GFAP, AQP4, and inflammatory mediators IL-1\u03b2, IL-6, VEGF increased, P\u2009<\u20090.05). Key rescue experiments demonstrated that Drp1 silencing (reduced p-Drp1 level, P\u2009<\u20090.05) reversed the aforementioned activation; however, co-administration of the Hippo pathway inhibitor XMU-MP-1 re-induced cell activation, proving that the Hippo pathway is a necessary downstream mediator of mitochondrial fission. In a diabetic rat model, elevated p-Drp1, Hippo pathway inhibition, and cell activation were similarly observed; the mitochondrial fission inhibitor Mdivi-1 alleviated this pathological process, whereas XMU-MP-1 counteracted its protective effects. This study systematically elucidates, from ex vivo to in vivo, the causal regulatory axis of \"HG- mitochondrial fission- Hippo pathway inhibition-M\u00fcller cell activation,\" providing experimental evidence and a potential target for developing DR-targeted therapeutic strategies centered on intervening in mitochondrial dynamics.\n\nID: 42393291\nTitle: Prevalence of and risk factors for diabetic retinopathy: The Thessaloniki Eye Study.\nAbstract: To estimate DR prevalence, risk factors, and undiagnosed disease in the Thessaloniki Eye Study. Cross-sectional, population-based study. Community examinations and home visits in Thessaloniki, Greece. Adults aged 60 years or older; 2468 with gradable fundus data or fundus examination were analysed. Self-reported diabetes mellitus (DM), demographics, ocular/systemic history, and lifestyle factors. DR prevalence/severity graded from fundus photographs using a modified Airlie House system; clinically significant macular oedema (CSMO), vision-threatening retinopathy (VTR), and DR risk factors. Among 2468 participants, DR prevalence was 6.9% (170/2468; 95% CI, 6.0%-8.0%). Among 352 participants with self-reported diabetes, 31.0% (109/352; 95% CI, 26.4%-36.0%) had DR; mild, moderate, severe non-proliferative DR, and proliferative DR were observed in 13.6%, 7.1%, 7.4%, and 2.8%, respectively. CSMO and VTR were present in 6.5% and 11.9%, respectively. Increased DR risk was associated with male gender (OR\u2009=\u20092.64), insulin therapy (OR\u2009=\u20094.87), and longer antihyperglycaemic treatment duration (OR\u2009=\u20091.05/year). Lower DR risk was associated with older age (OR\u2009=\u20090.87/year), regular alcohol intake (OR\u2009=\u20090.39), and migraines with aura (OR\u2009=\u20090.11). Among participants with DR, 73.9% were unaware of their diagnosis. DR affected nearly one-third of participants with diabetes, and most DR cases were undiagnosed. These findings support improved DR screening and education in older Greek adults.\n\nID: 42390174\nTitle: Proteomic Profiling of Optic Nerves From SMOX-Deficient Mice Identifies Regulators of Neuroinflammation and Axonal Damage in Optic Neuritis.\nAbstract: Visual dysfunction due to optic neuritis (ON) is an early clinical manifestation of multiple sclerosis (MS). ON is characterized by inflammation of the optic nerve, demyelination, axonal damage, and retinal ganglion cell (RGC) loss. Previously, we showed that spermine oxidase (SMOX), a polyamine catabolizing enzyme, modulates visual function in an experimental model of ON. Using proteomic analysis, the present study aimed to identify SMOX-regulated molecular pathways involved in ON-associated visual dysfunction. Experimental autoimmune encephalomyelitis (EAE) was induced in wild-type (WT) and SMOX-deficient (Smox KO) mice. Clinical scoring of mice was recorded daily. Optic nerves from WT and Smox KO EAE mice and their controls were collected and analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Pathway enrichment and comparative analyses were performed to identify key processes and pathways regulated by SMOX. Immunofluorescence was performed to detect changes in the expression of key proteins. Smox KO EAE mice showed delayed and reduced clinical scores. Pathway enrichment analysis identified several key processes affected in EAE, including regulation of the actin cytoskeleton, tight junction integrity, and platelet activation/aggregation. The comparative analysis of the WT EAE and Smox KO EAE proteomes, together with false discovery rate (FDR)-corrected pathway enrichment analysis, indicated attenuation of neuroinflammatory pathways in the SMOX-deficient optic nerve. Furthermore, SMOX deficiency restored key cytoskeletal and cellular-adhesion proteins essential for neuronal integrity. Immunofluorescence studies confirmed dysregulation of receptor for activated C kinase 1 (RACK1), actinin alpha 4 (ACTN4), high mobility group box 1 (HMGB1), and S100 calcium-binding protein B (S100B), critical proteins involved in immune signaling, cytoskeletal stability, and inflammation. These findings indicate the impact of SMOX on inflammation and cytoskeletal stabilization in ON and its potential as a therapeutic target in preserving vision in MS.\n\nID: 42381712\nTitle: Hybrid deep learning models for diabetic retinopathy stage classification using fundus images.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss in individuals with diabetes, making early and accurate detection essential for preventing severe complications. Automated classification of DR stages from retinal fundus images can assist clinicians in timely diagnosis and management. This study proposes a hybrid approach that combines deep learning-based feature extraction with traditional machine learning classifiers for automatic DR stage classification. Two datasets were used: Dataset A (DiabeticRetinopathy_Messidor_EyePACS_Preprocessed) and Dataset B (APTOS 2019 Blindness Detection). Three hybrid architectures were evaluated: MobileNetV2 with Support Vector Machine (SVM), MobileNetV2 with Random Forest (RF), and VGG16 with SVM. The models exploit convolutional neural networks for extracting discriminative features and employ conventional classifiers for robust decision-making. Grad-CAM and Score-CAM techniques were applied to enhance interpretability by visualizing the regions influencing model predictions. Experimental results on Dataset B show that MobileNetV2\u2009+\u2009SVM achieved an accuracy of 85%, precision of 72%, recall of 75%, and F1 score of 73%, while MobileNetV2\u2009+\u2009RF achieved an accuracy of 85%, precision of 74%, recall of 72%, and F1 score of 73%. These results indicate that lightweight CNNs combined with traditional classifiers can produce reliable and interpretable DR stage predictions.

A publicly available five-class DR fundus dataset of 3,500 color photographs graded using the International Clinical Diabetic Retinopathy (ICDR) scale was used. A standardized workflow was applied across eight Convolutional Neural Network (CNN) architectures (AlexNet, Densely Connected Convolutional Network 121 (DenseNet121), Residual Network 50 (ResNet50), eXtreme Inception (Xception), Mobile Network Version 2 (MobileNetV2), Efficient Network Version 2 B2 (EfficientNetV2B2), Inception Version 3 (InceptionV3), Visual Geometry Group 16 (VGG16)), including a 70/20/10 train/validation/test split, optional histogram-based contrast enhancement, strong on-the-fly augmentations, and class-balanced sampling. Seven architectures (DenseNet121, ResNet50, Xception, MobileNetV2, EfficientNetV2B2, InceptionV3, and VGG16) were initialized using ImageNet-pretrained weights and trained using a two-stage transfer-learning strategy with backbone freezing followed by partial fine-tuning, while AlexNet was implemented as a custom architecture and trained from randomly initialized weights. For five-class grading, VGG16 achieved the highest accuracy (0.7686) and weighted Jaccard index (0.6572), while EfficientNetV2B2 provided the best balanced accuracy (0.6128) and macro Area Under the Receiver Operating Characteristic Curve (AUROC 0.9158). Misclassifications were concentrated between adjacent severity levels. For binary DR screening, modern backbones achieved \u22650.94 accuracy and balanced accuracy; selected models reached AUROC \u22480.982-0.990 and Area Under the Precision-Recall Curve (AUPRC)\u2009\u2248\u20090.987-0.992.

We have previously shown that the risk of PDR is significantly elevated in individuals with intrauterine exposure to famine. However, the genetic mechanisms mediating this association remain unknown. The aim of the current study was to investigate the molecular underpinnings of famine-related PDR by performing genome-wide association (GWAS) and interaction studies (GWIS). We analysed n\u2009=\u20092925 patients with type 2 diabetes from the DOLCE cohort of Northern Ukraine, of whom n\u2009=\u20091364 were born during historical famine periods (1929-1949, including the Holodomor and World War II). PDR cases were defined as individuals with either diagnosed proliferative retinopathy, laser-treated diabetic retinopathy (DR) or blindness in either eye. GWAS and GWIS were performed using linear mixed model (LMM) adjusted for established risk factors and genetic relationship matrix. GWAS identified rs3795299 in IL22RA1 as the top signal (pLMM\u2009=\u20091.05\u2009\u00d7\u200910-6), which was also the strongest gene in the gene-based analysis (p\u2009=\u20093.19\u2009\u00d7\u200910-5), with suggestive enrichment of response to ketones (GO) and base excision repair (KEGG) pathways. In the GWIS, the strongest signal was rs1506783 in PAPPA2 (pLMM\u2009=\u20091.29\u2009\u00d7\u200910-7). A second biologically credible candidate was rs2230805 in ABCA1 (pLMM\u2009=\u20094.44\u2009\u00d7\u200910-6), reaching borderline genome-wide significance in gene-based analysis (p\u2009=\u20094.31\u2009\u00d7\u200910-6). Interaction analyses showed suggestive enrichment for nucleosomal DNA binding (GO), tryptophan metabolism and glycerolipid metabolism (KEGG) pathways. Furthermore, at nominal significance, we validated variants in previously reported diabetic retinopathy-associated genes, including TCF7L2, SLC2A1, SLC2A11 and VDR in the GWAS, as well as 13 variants in genes including VEGF, VEGFR1, ANGPT1, PLXDC2, SELP and PON2 in the GWIS. Our findings suggest that famine-related PDR susceptibility involves distinct developmental programming mechanisms, including altered insulin-growth signalling (PAPPA2) and lipid metabolism (ABCA1), whereas immune-related pathways (IL22RA1) may contribute to the conventional glycaemia-driven route to PDR through VEGF-mediated angiogenesis. These genes represent potential therapeutic targets and emphasize the importance of the perinatal environment in lifelong vascular health and disease.\n\nID: 42348183\nTitle: Loneliness, Blindness, and Major Eye Disease.\nAbstract: This cross-sectional study examines the association of loneliness with age-related macular degeneration, diabetic retinopathy, and glaucoma as well as with self-reported blindness.\n\nID: 42346900\nTitle: MultiRetNet: A Lightweight Explainable AI Approach to Diabetic Retinopathy Grading and DME Detection Using Fundus-OCT Fusion.\nAbstract: Diabetic retinopathy (DR) and diabetic macular oedema (DME) are two of the most significant preventable contributors to blindness in the adult population worldwide, yet current automated screening systems typically address each condition in isolation and rely on a single imaging modality. In this study, we propose a deep learning model that simultaneously grades DR severity and detects DME by fusing paired colour fundus and optical coherence tomography (OCT) images acquired from the same eye during the same clinical visit. Our architecture employs two parallel EfficientNet-B0 backbones pre-trained on ImageNet, one for each modality, whose 1280-dimensional feature vectors are concatenated into a 2560-dimensional joint representation. This fused representation passes through a shared fully connected block before branching into a three-class DR classification head and a binary DME detection head. We train and evaluate the model on a private dataset of 425 paired fundus and OCT eye images (850 images). The proposed architecture adopts feature-level fusion, in which modality-specific deep features are independently extracted from fundus and OCT images using separate convolutional backbones and subsequently concatenated to form a joint representation for multi-task learning. On the held-out test set (n= 85), the fusion model achieves 82.4% DR accuracy (area under the receiver operating characteristic curve [AUC] = 0.929, macro sensitivity = 0.81, macro specificity = 0.905) and 97.6% DME accuracy (AUC = 0.999, sensitivity = 0.833, specificity = 1.000). The fusion model detects 10 of 12 DME-positive eyes compared with only 7 of 12 for either the fundus-only or OCT-only baselines, representing a 43% relative improvement in DME sensitivity. Stratified five-fold cross-validation (n = 425 aggregated predictions) corroborates these findings, with the fusion model reaching 87.1% DR accuracy (AUC = 0.978) and 99.1% DME accuracy (AUC = 1.000). Gradient-weighted class activation mapping visualisations confirm that the fundus branch attends to clinically relevant macular lesions, whereas the OCT branch highlights retinal layer disruptions and subretinal fluid, providing interpretability. To the best of our knowledge, the proposed MultiRetNet is the first lightweight, task-specific multimodal architecture to jointly grade DR severity and detect DME from paired same-eye, same-visit fundus and OCT images through explicit feature-level fusion within a single end-to-end multi-task framework, distinct from recent generalist ophthalmic foundation models, supporting the value of multimodal fusion for comprehensive diabetic eye screening pending external validation.\n\nID: 42346597\nTitle: Diabetes May Modulate the Association Between Age and Optical Coherence Tomography Angiography Parameters: A Serial, Cross-Sectional Study.\nAbstract: Purpose: We investigated the association between age and retinal microvasculature parameters as measured by optical coherence tomography angiography (OCTA) and the modifying effect of diabetes status on this association. Methods: In this serial, cross-sectional study, 3 \u00d7 3 mm2 macular OCTA images were obtained from healthy adults and adults with diabetes mellitus (DM) with no diabetic retinopathy (DR) or with mild non-proliferative DR (NPDR). The parameters analyzed included foveal avascular zone (FAZ) area and perimeter, vessel density (VD), vessel length density (VLD), and flow index (FI) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP). The associations between OCTA parameters and age were explored using multivariable linear regression models. Results: For the included 1855 patients (1855 eyes) (49% male; mean age: 55 years), the results were as follows: no diabetes (N = 217), DM no DR (N = 1352), and mild NPDR (N = 286). Increasing age was significantly associated with decreased SCP and DCP VD and VLD in the diabetic and non-diabetic groups. The slope of association between SCP and DCP FI and age in the diabetic patients was significantly different than that in the control patients. Conclusions: The strength of the association between aging and OCTA parameters differed significantly between the controls and those with early retinopathy, pointing to a potentially altered retinal vascular homeostasis secondary to diabetic pathophysiology. This finding offers insight into the early pathological biomarkers of DR and may guide early DR management for patients based on personalized risk scores.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

The phase III BALATON and COMINO trials demonstrated non-inferiority to aflibercept at week 24, and several real-world cohorts have subsequently emerged. The aim of this systematic review and meta-analysis was to estimate the pooled effect of faricimab on visual acuity, treatment burden, anatomical outcomes, and safety in this indication. PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials were systematically searched from inception to 1 May 2026 for studies reporting outcomes following intravitreal faricimab. Risk of bias was assessed in duplicate using the Cochrane Risk of Bias 2 tool for the randomised evidence and the Risk Of Bias In Non-randomised Studies of Interventions tool for the observational evidence, with single-arm cohorts evaluated as pre-post comparisons. The primary visual acuity outcome was pooled using random-effects meta-analysis with Hartung-Knapp-Sidik-Jonkman adjustment, stratified by treatment status, while outcomes precluded from pooling by methodological heterogeneity were synthesised narratively. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation framework. Ten studies comprising 1,620 eyes met eligibility criteria, including the BALATON and COMINO randomised controlled trials and nine non-randomised cohorts. The pooled mean change in best-corrected visual acuity at approximately 6 months was +\u200916.89 Early Treatment Diabetic Retinopathy Study letters (95% confidence interval 16.05 to 17.72) in treatment-na\u00efve eyes and +\u20098.73 letters (95% confidence interval 4.75 to 12.71) in refractory switch cohorts, with negligible between-study heterogeneity in both analyses. Narrative synthesis was consistent with treatment interval extension following initiation of or switch to faricimab, statistically significant reductions in central retinal thickness across studies, and a short-term safety profile without identified retinal vasculitis events. The synthesis is consistent with intravitreal faricimab use being associated with visual and anatomical improvement in macular oedema secondary to retinal vein occlusion, with the treatment-na\u00efve pooled estimate primarily reflecting registration trial data and the switch cohort estimate characterising refractory phenotypes.\n  --- END ACTUAL ABSTRACT FOR 42426919 ---\n\n- ERROR: You cited ID: 42397510 for the quote: \"High-glucose-induced mitochondrial fission promotes M\u00fcller cell activation via suppression of the Hippo pathway.\"\n  FACT: Strict Misquote Detected!

This study aimed to untangle the critical role and mechanism of mitochondrial fission in this process. We found that under HG conditions, the level of p-Drp1 was significantly elevated (P\u2009&lt;\u20090.05), driving excessive mitochondrial fission. Functional experiments confirmed that artificially enhancing mitochondrial fission directly inhibited the Hippo signaling pathway (levels of core proteins p-MST1/2, p-LATS1, and p-YAP decreased, P\u2009&lt;\u20090.05, and YAP translocated to the nucleus), thereby activating M\u00fcller cells (expression of marker proteins GS and Kir4.1 decreased, while expression of GFAP, AQP4, and inflammatory mediators IL-1\u03b2, IL-6, VEGF increased, P\u2009&lt;\u20090.05). Key rescue experiments demonstrated that Drp1 silencing (reduced p-Drp1 level, P\u2009&lt;\u20090.05) reversed the aforementioned activation; however, co-administration of the Hippo pathway inhibitor XMU-MP-1 re-induced cell activation, proving that the Hippo pathway is a necessary downstream mediator of mitochondrial fission.

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\nThe claim evaluated concerns the therapeutic potential of SPG302 and related neuroprotective mechanisms in mitigating diabetic retinal neuropathy (DRN), characterized by early ganglion cell loss and synaptic degeneration, and the potential for synaptic regeneration and preservation of visual function in conditions such as diabetes and glaucoma.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nDiabetic retinopathy manifests early as diabetic retinal neuropathy (DRN), involving neurodegenerative processes that precede microvascular injury. Recent literature supports a shift toward neurovascular unit (NVU) protection, where pharmacological agents like SPG302 target synaptic and mitochondrial integrity. Evidence suggests that preserving retinal ganglion cells (RGCs) and synaptic markers through targeting metabolic pathways (such as Nrf2, AMPK, and nuclear receptors) may prevent progressive visual loss in diabetes and glaucoma.\n\n### [INTRODUCTION & JUSTIFICATION]\nDiabetic retinopathy is no longer classified solely as a microvascular pathology; it is increasingly recognized as a neurovascular degenerative disease involving coordinated injury to the retinal neurovascular unit. Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function, decreased inner retina synaptic markers, and increased reactive gliosis and cell death. The molecular mechanisms driving this include mitochondrial dysfunction, where high glucose flux promotes mitochondrial reactive oxygen species overproduction and oxidative stress. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma, another leading cause of blindness associated with early synapse loss in the retina. Db/db mice demonstrated significant loss of GC ERG signal and GC cell number, decreased PSD95 and synaptophysin expression indicative of synapse loss, as well as increased reactive gliosis and expression of cell death markers such as pBAD and BAX. SPG302 treatment effectively preserved retinal integrity by reversing these changes. Such findings underscore the necessity of shifting clinical thinking from late vascular rescue toward mechanism-based neurovascular protection.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Neurodegeneration in glaucoma often involves transsynaptic degeneration extending into secondary and higher-order visual brain regions.\n*   In diabetic retinopathy, mitochondrial fission acts as a pathological initiator, suppressing the Hippo pathway and promoting M\u00fcller cell activation.\n*   GPR75 knockdown provides a therapeutic strategy for alleviating mitochondrial dysfunction in retinal ganglion cells via the AMPK pathway.\n*   Sigma1 receptor (Sig1R) activation provides durable neuroprotection by coordinating redox, mitochondrial, and cell-survival pathways.\n*   Synaptic proteins such as Syntaxin-4 regulate membrane trafficking essential for maintaining neuronal homeostasis in the retina.\n*   Short-chain fatty acids like propionic acid show promise in reducing serum neurofilament light chain levels, indicating attenuation of neuroaxonal injury.\n*   The interaction between microglia and M\u00fcller cells is modulated by fibroblast growth factor 1 (FGF1), which is downregulated in glaucomatous retinas.\n*   Intranasal delivery of neuroprotective agents offers a potential non-invasive strategy for posterior segment ocular disease, bypassing the blood-retinal barrier.\n*   Panoptosis, an integrated programmed cell death modality, serves as a dynamic framework for interpreting inflammatory neurovascular degeneration in diabetic retinopathy.\n*   Targeting the liver-brain axis via Licochalcone A or other agents may provide systemic protection against metabolic neurodegeneration.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Within the RNVU, calcium ions coordinate neurotransmission, glial activation, vascular tone, and blood-retinal barrier maintenance, and calcium dysregulation is emerging as a unifying pathogenic hub across these conditions. Although upstream triggers differ, including mechanical stress in glaucoma, hyperglycemia in DR, oxidative damage in AMD, ischemic energy failure in RIR, and amyloid-\u03b2-driven endoplasmic reticulum stress in AD, all converge on disruption of intracellular calcium homeostasis, producing shared downstream consequences including excitotoxic injury of retinal ganglion cells (RGCs), M\u00fcller cell reactive gliosis, and pericyte hypercontraction. Broad-spectrum calcium channel blockade has shown limited clinical success, underscoring the need for cell-type-specific and pathway-selective approaches. This review therefore catalogs key interventional nodes, including transient receptor potential (TRP) channel antagonists, T-type calcium channel inhibitors, calcium/calmodulin-dependent protein kinase II (CaMKII) suppressors, and mitochondrial permeability transition pore (mPTP) inhibitors, and discusses how precision targeting of these pathways may restore RNVU homeostasis and open a therapeutic window into central nervous system (CNS) degenerative disorders."

In this study, we investigated the protective effects of norrin against hyperglycemia-induced retinal neurodegeneration and elucidated its underlying molecular mechanisms in diabetic mice. We found that retinal neurodegeneration may precede microvascular leakage in diabetic retinas. Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Intravitreal supplementation of norrin markedly attenuated hyperglycemia-induced neurodegenerative processes, leading to retinal ganglion cell (RGC) apoptosis, including oxidative stress, inflammation, and neuropathological alterations such as reactive gliosis, glutamate excitotoxicity, and synaptic dysfunction. Norrin also reduced hyperglycemia-induced microvascular leakage and RGC apoptosis by normalizing vascular endothelial growth factor (VEGF) overexpression and restoring pigment epithelium-derived factor (PEDF) levels. Notably, PEDF upregulated by norrin effectively suppressed neurodegenerative processes induced by hyperglycemia or VEGF, thereby preserving RGC function. These findings identify norrin as a critical modulator of hyperglycemia-induced retinal neurodegeneration through restoration of the VEGF-PEDF balance. Our results highlight norrin as a potential therapeutic target for early neurodegenerative changes in diabetic retinopathy."

Patients often develop other symptoms, such as deafness and neurological dysfunction. Wolfram syndrome is caused by mutations in the WFS1 gene, which encodes wolframin protein. Despite decades of intensive research, the complex mechanisms of optic neuropathy are not fully understood, and there are currently no therapies to prevent vision loss in Wolfram patients. Here, we showed that the Wfs1 knockout mice produced by the Estonian group, in which exon 8 of the Wfs1 gene was disrupted, exhibit a progressive loss of visual acuity, optic disc pallor and severe optic nerve damage. We tested the efficiency of gene therapy using AAV2 to deliver human WFS1 to retinal ganglion cells in Wfs1 knockout mice. Our results provide the first evidence that intravitreal injection of human WFS1 has significant neuroprotective effects on retinal ganglion cells and their axons and slows the loss of visual acuity. These results demonstrate that WFS1 is able to provide both functional and structural protection to retinal ganglion cells in Wfs1 knockout mice and provide important evidence for the efficacy of WFS1 as a neuroprotective treatment for Wolfram syndrome. These results demonstrate the promising effects of gene therapy for Wolfram syndrome and encourage future research aimed at conducting clinical trials in patients."

Retinal inflammation and angiogenesis contribute largely to the neuronal degeneration in DIR. The current study is aiming to test the effect of oral betanin doses in protection from DIR in rats along with a network pharmacology study to investigate an assumption that betanin may inhibit nuclear factor-\u03ba B (NF-\u03baB). Three rat groups were assigned as vehicle, DIR, and DIR\u00a0+\u00a0Betanin 100\u00a0mg/kg. Molecular docking indicated the possible binding between betanin and NF-\u03baB while the bioinformatic study highlighted a relation between this possible inhibition and suppression of NOD-like receptor pyrin domain-containing protein 3/vascular endothelial growth factor (NLRP3/VEGF) axis. The rat experimental study validated this assumption and indicated a protective effect for betanin on rat retinas as shown by routine hematoxylin and eosin staining (retinal thickness and ganglion cell count) and periodic acid-Schiff staining that was mediated through mitigating expression/protein level for of NF-\u03baB, NLRP3, TNF-\u03b1, IL-6 and VEGF proteins. Immunohistochemistry showed that betanin was able to suppress retinal content of the glial fibrillary acidic protein (GFAP). In conclusion, the current study indicated that betanin was a good candidate for DIR in rats through suppression of the inflammatory cascade and may be suggested for diabetic patients if appropriated clinical studies will be available."

So, early diagnosis and proper treatment can preserve the useful vision in lifetime. The objective of the study was to determine the importance of ganglion cell complex (GCC) analysis as a parameter for diagnosis of glaucoma. This case control study was conducted in the Department of Ophthalmology, Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) General Hospital, Bangladesh over a period of one year from July 2017 to June 2018. Twenty five (25) Type-2 Diabetes control subjects and 50 subjects with Type-2 diabetes were divided into two groups, 25 diabetic with pre perimetric and 25 diabetic with perimetric glaucoma. In this study, there was no significant difference in age (50.92\u00b15.53 years vs. 52.44\u00b14.75 years vs. 52.64\u00b17.80 years), gender. Regarding Optical coherence tomography (OCT) Retinal Nerve Fiber Layer (RNFL) of right eyes of the study subjects, superior and inferior RNFL were significantly thinner in both pre-perimetric right eye (109.18\u00b18.95 and 111.21\u00b110.53) and perimetric right eye (90.28\u00b18.94 and 91.51\u00b17.87) comparing normal eyes (129.12\u00b12.68 and 132.17\u00b13.22).

Regarding OCT GCC layer of right eyes of the study subjects, superior and inferior GCC layer were significantly lower in both pre-perimetric (87.66\u00b13.81 and 89.70\u00b14.98) and perimetric (77.48\u00b16.97 and 79.21\u00b16.06) right eyes comparing normal eyes (104.53\u00b12.73 and 106.88\u00b13.29). Regarding OCT GCC layer of left eyes of the study subjects, superior and inferior GCC layer were significantly lower in both pre-perimetric (84.88\u00b13.82 and 87.21\u00b13.77) and perimetric (81.08\u00b19.51 and 80.01\u00b110.02) left eyes comparing normal eyes (102.64\u00b12.29 and 105.20\u00b11.27). GCC parameter is useful tool for diagnosis of Glaucoma. It has same ability to discriminate eyes with glaucoma and non glaucomatous eyes compared to RNFL. In glaucoma, GCC layer is significantly thin which correlates strongly with glaucomatous damage. According to our result GCC layer analysis is important investigation to diagnosis of Glaucoma."

Prospective observational cohort study. T2DM patients without clinical retinopathy at baseline and after a 2-year follow-up, along with age- and sex-matched healthy controls, were recruited from the community in Guangzhou, China. Measurements of macular GCIPLT, retinal thickness (RT), and SCP vessel density were conducted at baseline and at the 2-year follow-up. Linear mixed-effects models were used to estimate absolute and relative rates of changes and to compare absolute rates between the 2 groups. A total of 282 eyes (141 in the control group and 141 in the non-DR group) were included in the analysis. Significant reductions in GCIPLT and GCIPLT/RT occurred only in the non-DR group, with GCIPLT decreasing by -0.229 \u00b5m/y (95% CI = -0.313 to -0.144; P < .001) and 0.324 % (95% CI = 0.444 to 0.204; P < .001), approximately 5-fold faster than in the control group.

The mechanisms leading to neuro-retinal cell loss before vascular complications manifest in diabetes remain poorly understood. In this study, we investigated the neuronal RNA-binding protein HuD as a novel regulator of neuro-retinal degeneration in the early stage of diabetes. We determined the expression of HuD and alpha-crystallin A (CRYAA) in the retinal ganglion cell layer. HuD and CRYAA were down-regulated in the retinas of streptozotocin-induced diabetic rats and in neuro-retinal cells (R-28) treated with high glucose. Cryaa mRNA was identified as a novel target transcript of HuD, and we demonstrated that HuD post-transcriptionally regulates the expression of Cryaa mRNA by binding to its 3'-untranslated region. Silencing and overexpression of HuD positively regulated the expressions of Cryaa mRNA and protein. We demonstrated that the increase in inflammatory cytokines such as TNF\u03b1, IL-1\u03b2, and IL-6 in R-28 cells under hyperglycemic conditions was a result of both CRYAA and HuD levels. Silencing HuD and CRYAA enhanced high glucose-induced R-28 cell death, whereas their overexpression alleviated this effect. HuD post-transcriptionally regulates CRYAA expression, influencing the function and viability of neuro-retinal cells under diabetic conditions.

In this study, we examined whether EMPA protects against N-methyl-d-aspartic acid (NMDA)-induced retinal excitotoxicity and the mechanisms underlying its protective effects. Male Sprague-Dawley rats (7-8\u00a0weeks old) were used in this study. The number of cells in the ganglion cell layer (GCL) decreased 7\u00a0days after intravitreal injection of NMDA (50\u00a0nmol). Simultaneous intravitreal injection of EMPA (50 and 100\u00a0nmol) and NMDA reduced NMDA-induced cell loss in a dose-dependent manner. The protective effect of EMPA was significantly attenuated by the AMP-activated protein kinase (AMPK) inhibitor, compound C (10\u00a0nmol). NMDA increased the number of terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive cells in the GCL 6\u00a0h after injection, and the response was significantly, but not completely, attenuated by EMPA. These results suggest that EMPA protects against NMDA-induced retinal excitotoxicity in rats. The protective effect of EMPA may be partly attributed to the activation of the AMPK pathway and inhibition of neuronal cell apoptosis."

However, the detailed molecular regulatory mechanism has not yet been thoroughly examined. In this study, primary mouse RGCs were stimulated with different concentrations of glucose, and mouse was intraperitoneally injected with streptozotocin (STZ) to construct DR model in vitro and in vivo. We found that compared to normal controls, RNA binding motif protein 15 (RBM15) was significantly upregulated in high glucose-treated RGCs and STZ-induced mice. RBM15 silence restored cell viability and inhibited cell apoptosis and cell death in high glucose-triggered RGCs. In parallel, RBM15 knockdown distinctly improved pathological damage such as thinning of retinal tissue thickness and loss of RGCs in STZ-modeling mice. Interestingly, the production of inflammatory cytokines and the expression of Cleaved caspase-1, NLRP3 and GSDMD-N were significantly reduced by RBM15 silence in vivo and in vitro. Mechanistically, RBM15 bound to kruppel like factor 6 (KLF6) mRNA to promote m6A modification and stabilize KLF6 mRNA, upregulating KLF6 expression in model cells and model mice retinal tissues. KLF6 overexpression increased the production of inflammatory cytokines and the expression of proteins related to pyroptosis, reversing the protective effects of RBM15 silence in high glucose-treated RGCs and diabetic retina. In conclusion, RBM15 is upregulated by high glucose, and stabilizes KLF6 mRNA to activate NLRP3-mediated pyroptosis pathway, exacerbating inflammation and apoptosis of RGCs and accelerating the progression of DR."

Diabetic patients underwent detailed systemic and ophthalmic examination including automated pupillometry. The pupillometer used a white stimulus and was equipped with a high-resolution infrared (880\u2009nm) camera. Static pupillary diameters were captured at different levels of background intensity-photopic high (100\u2009cd/m2), photopic low (10\u2009cd/m2), mesopic high (1\u2009cd/m2), and mesopic low (0.1\u2009cd/m2).

The amplitude of contraction and velocity of contraction was significantly lower in diabetic patients compared to controls (p\u2009<\u20090.001), and between DWR compared to DWOR (p\u2009<\u20090.001). Percent pupillary contraction differed between DWR and controls (p\u2009=\u20090.001) There was a significant difference in superior RNFL thickness between DWR and DWOR (p\u2009=\u20090.032). The superior quadrant RNFL correlated with the maximum number of pupillometry parameters. The amplitude and velocity of contraction are affected early in diabetic autonomic dysfunction. There is a relationship between RNFL thickness and pupillometry parameters in diabetic patients, indicating simultaneous neurodegeneration and autonomic neuropathy."

In the brain, defects in \u03b3-aminobutyric acid synaptic transmission are associated with pathophysiological and neurodegenerative disorders, whereas glucagon-like peptide-1 has demonstrated neuroprotective effects. However, it is not yet clear whether diabetes causes alterations in inhibitory input to retinal ganglion cells and whether and how glucagon-like peptide-1 protects against neurodegeneration in the diabetic retina through regulating inhibitory synaptic transmission to retinal ganglion cells. In the present study, we used the patch-clamp technique to record \u03b3-aminobutyric acid subtype A receptor-mediated miniature inhibitory postsynaptic currents in retinal ganglion cells from streptozotocin-induced diabetes model rats. We found that early diabetes (4 weeks of hyperglycemia) decreased the frequency of GABAergic miniature inhibitory postsynaptic currents in retinal ganglion cells without altering their amplitude, suggesting a reduction in the spontaneous release of \u03b3-aminobutyric acid to retinal ganglion cells. Topical administration of glucagon-like peptide-1 eyedrops over a period of 2 weeks effectively countered the hyperglycemia-induced downregulation of GABAergic mIPSC frequency, subsequently enhancing the survival of retinal ganglion cells. Concurrently, the protective effects of glucagon-like peptide-1 on retinal ganglion cells in diabetic rats were eliminated by topical administration of exendin-9-39, a specific glucagon-like peptide-1 receptor antagonist, or SR95531, a specific antagonist of the \u03b3-aminobutyric acid subtype A receptor. Furthermore, extracellular perfusion of glucagon-like peptide-1 was found to elevate the frequencies of GABAergic miniature inhibitory postsynaptic currents in both ON- and OFF-type retinal ganglion cells. This elevation was shown to be mediated by activation of the phosphatidylinositol-phospholipase C/inositol 1,4,5-trisphosphate receptor/Ca 2+ /protein kinase C signaling pathway downstream of glucagon-like peptide-1 receptor activation. Moreover, multielectrode array recordings revealed that glucagon-like peptide-1 functionally augmented the photoresponses of ON-type retinal ganglion cells. Optomotor response tests demonstrated that diabetic rats exhibited reductions in visual acuity and contrast sensitivity that were significantly ameliorated by topical administration of glucagon-like peptide-1. These results suggest that glucagon-like peptide-1 facilitates the release of \u03b3-aminobutyric acid onto retinal ganglion cells through the activation of glucagon-like peptide-1 receptor, leading to the de-excitation of retinal ganglion cell circuits and the inhibition of excitotoxic processes associated with diabetic retinopathy. Collectively, our findings indicate that the \u03b3-aminobutyric acid system has potential as a therapeutic target for mitigating early-stage diabetic retinopathy. Furthermore, the topical administration of glucagon-like peptide-1 eyedrops represents a non-invasive and effective treatment approach for managing early-stage diabetic retinopathy."

The drugs currently used for treatment, such as ranibizumab, mainly focus on the middle and late periods of DR, and thus do not meet the clinical need. Here, the potential mechanisms by which compound Danshen Dripping Pills (CDDP) might protect against early DR were investigated. Methods: Db/db mice were used to establish a DR model. The initial weights and HbA1c levels of the mice were monitored, and retinal pathology was assessed by hematoxylin-eosin (HE) staining. The vascular permeability of the retina and thickness of each retinal layer were measured, and electroretinogram were performed together with fundus fluorescein angiography and optical coherence tomography. The levels of inflammatory factors were examined in retinal tissue, as well as those of intercellular adhesion molecule 1 (ICAM-1), IL-6, and monocyte chemoattractant protein 1 (MCP-1) in the serum using ELISA. Immunohistochemistry was used to evaluate levels of vascular endothelial growth factor (VEGF), B-cell lymphoma 2 (Bcl-2), and Bclassociated X protein (Bax). Retinal cell injury and apoptosis were examined by TdT-mediated dUTP Nick End Labeling (TUNEL) assays. Results: The data showed that CDDP significantly improved cellular disarrangement. Imaging data indicated that CDDP could reduce vascular permeability and the amplitude of oscillatory potentials (OPs), and restore the thickness of the ganglion cell layer. Moreover, CDDP reduced the expression levels of inflammatory factors in both the retina and serum. Conclusion: These findings strongly suggest that CDDP prevents early DR through vascular and neuroprotection."

Diabetic macular edema (DME) is an ocular complication in patients with diabetes, and it can impair vision significantly. DME is a disorder of the neurovascular system, and it causes obstructions of the retinal capillaries, damage of the blood vessels, and hyperpermeability due to the expression and action of vascular endothelial growth factor (VEGF). These changes result in hemorrhages and leakages of the serous components of blood that result in failures of the neurovascular units (NVUs). Persistent edema of the retina around the macula causes damage to the neural cells that constitute the NVUs resulting in diabetic neuropathy of the retina and a reduction in vision quality. The macular edema and NVU disorders can be monitored by optical coherence tomography (OCT). Neuronal cell death and axonal degeneration are irreversible, and their development can result in permanent visual loss. Treating the edema before these changes are detected in the OCT images is necessary for neuroprotection and maintenance of good vision. This review describes the effective treatments for the macular edema that are therefore neuroprotective."

Macular transversal sections were analyzed for photoreceptors, bipolar cells, horizontal cells, ganglion cells, their synaptic connections, and M\u00fcller cells using immunohistochemistry and confocal microscopy. The densities of bipolar cells, horizontal cells, and ganglion cells and the thickness of the inner plexiform layer (IPL) were quantified around the fovea. In the macula, cone photoreceptors elongated their axons to establish synapses with bipolar and horizontal cells in intraretinal cysts. Bipolar cells were reduced in the DM group compared to the control (P < 0.001), and rod bipolar cells showed morphological alterations in the cell body and synaptic terminals in both diabetic groups. Morphological changes were observed in both plexiform layers, with a decrease in the IPL thickness in DR. Horizontal cell terminals sprouted into the outer and inner retina in DR, despite no density differences existing between DM and control (P = 0.498).

Their pathogenesis is intricately linked to oxidative stress-induced dysfunction of retinal pigment epithelial (RPE) cells and subsequent retinal degeneration. Macroautophagy/autophagy, a critical cellular degradation pathway, plays a vital role in maintaining RPE homeostasis, yet its dysregulation in retinal degenerative diseases remains poorly understood. In this study, we observed that sodium iodate (NaIO3), an oxidative stress inducer, triggered lysosomal dysfunction via lysosomal membrane permeabilization (LMP), thereby impairing autophagic flux in RPE cells and exacerbating retinal degeneration. RNA sequencing identified LAMP3 (lysosomal-associated membrane protein 3) as a downregulated gene following NaIO3 treatment. Functionally, LAMP3 overexpression alleviated NaIO3-induced LMP, improved lysosomal function, and alleviated autophagic impairment. Furthermore, upregulation of LAMP3 reduced oxidative stress and apoptosis in RPE cells, while alleviating retinal degeneration in a NaIO3-induced mouse model. Mechanistically, our data suggested that NaIO3 upregulated the transcription factor SNAI1, which acts as a transcriptional repressor of LAMP3. SNAI1 knockdown increased LAMP3 expression, thereby facilitating the recovery of lysosomal function and the alleviation of autophagic impairment. Collectively, our findings indicate that the SNAI1-LAMP3 axis contributes to the regulation of the autophagy-lysosomal pathway in retinal degeneration, highlighting a potential therapeutic target for delaying disease progression.Abbreviations: AMD: age-related macular degeneration; AO: acridine orange; Baf A1: bafilomycin A1; BAX: BCL2-associated X protein; BCL2: B cell leukemia/lymphoma 2; BSA: bovine serum albumin; CCK-8: cell counting kit-8; ChIP: chromatin immunoprecipitation; CM-H2DCFDA: chloromethyl-2',7'-dichlorodihydrofluorescein diacetate; CTSD: cathepsin D; DAPI: 4',6-diamidino-2-phenylindole; DEGs: differentially expressed genes; DHE: dihydroethidium; EdU: 5-ethynyl-2'-deoxyuridine; ERG: electroretinography; GSEA: gene set enrichment analysis; H&E: hematoxylin and eosin; HsRPE: human primary retinal pigment epithelial; JC-1: 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolylcarbocyanine iodide; LAMP1: lysosomal-associated membrane protein 1; LAMP2: lysosomal-associated membrane protein 2; LAMP3: lysosomal-associated membrane protein 3; LGALS3: lectin, galactose binding, soluble 3; LLOMe: leu-leu methyl ester; LMP: lysosomal membrane permeabilization; MAP1LC3B/LC3B: microtubule-associated protein 1 light chain 3 beta; MMP: mitochondrial membrane potential; NAC: N-acetyl-L-cysteine; NaIO3: sodium iodte; NC: negative control; OCT: optical coherence tomography; PCA: principal component analysis; PI: propidium iodide; qRT-PCR: quantitative real-time polymerase chain reaction; Rapa: rapamycin; ROS: reactive oxygen species; RP: retinitis pigmentosa; RPE: retinal pigment epithelium; RPE65: retinal pigment epithelium 65; siRNA: small interfering RNA; SNAI1: snail family zinc finger 1; SQSTM1/p62: sequestosome 1; TJP1/ZO-1: tight junction protein 1; ZNF135: zinc finger protein 135."

While the most common inherited retinal diseases (IRDs) involve defects in rod and/or cone function, another group (referred to as congenital stationary night blindness (CSNB)) results from defects in glutamate release from photoreceptors, or conversion of the glutamatergic signal in bipolar cells. One example results from mutations in the CACNA2D4 gene, which encodes a subunit of the voltage-gated calcium channel that is critical for glutamate release from both rod and cone photoreceptors. Mutations in CACNA2D4 result in a range of phenotypes in human patients, from incomplete CSNB to rod-cone dystrophy. In the CACNA2D4 knockout mouse ( \u03b12\u03b44 -/- ), there is slow photoreceptor degeneration, the photoreceptor-to-bipolar cell synapse is disorganized, and the retina lacks scotopic and photopic full-field electroretinogram b-waves; this also results in low visual acuity. Using adult \u03b12\u03b44 -/- mice, we show that recombinant adeno-associated virus (rAAV)-mediated gene therapy directed to rod photoreceptors prevents rod degeneration, restores synaptic organization, retinal function, and improves visual acuity under both light- and dark-adapted conditions. This rescue was maintained for up to 14 months post-treatment. Together, our results demonstrate that synaptic structure and function can be restored in the mature mouse retina in a model of complete synaptic disorganization.

Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits.

SPG302, a pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and demonstrates neuroprotective potential in both diabetic and glaucomatous models by mitigating inner retinal damage and preserving visual function.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm of diabetic retinopathy has shifted from a primarily microvascular perspective to a neurovascular degenerative disorder where retinal ganglion cell (RGC) integrity and synaptic stability serve as critical therapeutic targets. The provided literature establishes that DRN manifests as inner retinal degeneration with a loss of ganglion cells and a reduction in synaptic markers, such as PSD95 and synaptophysin. SPG302 stands out as a \"synaptogenic small molecule\" that demonstrates broad applicability across neurodegenerative conditions, including glaucoma and diabetes, by reversing synaptic loss. By promoting synaptogenesis, SPG302 preserves retinal structural integrity and functional output as measured by electroretinography. This approach is aligned with the broader understanding that restoring synaptic architecture and metabolic homeostasis is requisite for preventing the irreversible vision loss associated with diabetic and glaucomatous neurodegeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Neurodegeneration, particularly RGC loss and synaptic impairment, often precedes clinical microvascular symptoms in diabetic retinopathy.\n*   SPG302 acts as a synaptogenic agent, capable of mitigating retinal injury across different disease etiologies, including glaucoma.\n*   The synaptic dysfunction in diabetes and glaucoma involves common molecular pathways, such as the modulation of postsynaptic density (PSD) proteins.\n*   Exosomes derived from specific physiological states (like hibernation) have been identified as potential mediators of intrinsic neuroprotection, suggesting novel intercellular signaling pathways.\n*   The use of GLP-1 receptor agonists and traditional Chinese medicines (e.g., Danshen, Ginsenoside Rg1) provides alternative, multi-target strategies for mitigating neuroinflammation in the retina.\n*   Calcium dysregulation acts as a \"unifying pathogenic hub\" for neurovascular unit dysfunction across multiple neurodegenerative diseases.\n*   Targeting the autophagy-lysosomal pathway (e.g., via the SNAI1-LAMP3 axis) represents an emerging therapeutic direction to preserve RPE and retinal neurons.\n*   Metabolic variability (e.g., glucose flux and uric acid levels) significantly influences the rate of ganglion cell thinning in diabetic patients without retinopathy.\n*   Advanced multimodal imaging (e.g., SS-OCTA) allows for the early detection of neurovascular uncoupling, which serves as a biomarker for disease progression.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function, decreased inner retina synaptic markers, and increased reactive gliosis and cell death. Loss of glutamatergic synapses in the retina precedes, and may contribute to, overt neuron loss in DR, thus offering a potential new point for therapeutic intervention. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma, another leading cause of blindness associated with early synapse loss in the retina. To evaluate potential protective effects of SPG302 in DR, db/db mice (a diabetic mouse model with an inactivation mutation in the leptin receptor) were treated with intraperitoneal SPG302 or vehicle for 8 weeks (16-24 weeks of age). Db/+ mice served as an additional control. Db/db mice demonstrated weight gain, hyperglycemia, insulin intolerance, and glucose intolerance, while db/+ mice did not. SPG302 treatment did not change these metabolic parameters. Following treatment, GC function was assessed using electroretinography (ERG). Mice were then euthanized for quantification of retinal GCs, synaptic markers, glial markers, and markers of cell death using immunofluorescence staining and Western blot methods. Db/db mice demonstrated significant loss of GC ERG signal and GC cell number, decreased PSD95 and synaptophysin expression indicative of synapse loss, as well as increased reactive gliosis and expression of cell death markers such as pBAD and BAX. SPG302 treatment effectively preserved retinal integrity by reversing these changes. Thus, SPG302 has therapeutic potential for protecting the inner retina and mitigating DRN in diabetes.\n\nID: 42352232\nTitle: Calcium at the Helm: Mechanisms and Therapeutic Targets in the Retinal Neurovascular Unit.\nAbstract: Retinal neurovascular unit (RNVU) dysfunction underlies major blinding and neurodegenerative conditions including glaucoma, diabetic retinopathy (DR), age-related macular degeneration (AMD), retinal ischemia-reperfusion (RIR) injury, and Alzheimer's disease (AD)-associated retinopathy. Within the RNVU, calcium ions coordinate neurotransmission, glial activation, vascular tone, and blood-retinal barrier maintenance, and calcium dysregulation is emerging as a unifying pathogenic hub across these conditions. Although upstream triggers differ, including mechanical stress in glaucoma, hyperglycemia in DR, oxidative damage in AMD, ischemic energy failure in RIR, and amyloid-\u03b2-driven endoplasmic reticulum stress in AD, all converge on disruption of intracellular calcium homeostasis, producing shared downstream consequences including excitotoxic injury of retinal ganglion cells (RGCs), M\u00fcller cell reactive gliosis, and pericyte hypercontraction. Broad-spectrum calcium channel blockade has shown limited clinical success, underscoring the need for cell-type-specific and pathway-selective approaches. This review therefore catalogs key interventional nodes, including transient receptor potential (TRP) channel antagonists, T-type calcium channel inhibitors, calcium/calmodulin-dependent protein kinase II (CaMKII) suppressors, and mitochondrial permeability transition pore (mPTP) inhibitors, and discusses how precision targeting of these pathways may restore RNVU homeostasis and open a therapeutic window into central nervous system (CNS) degenerative disorders.\n\nID: 42196293\nTitle: The Metabolic Architecture of Glaucoma: A Unified Framework of Cofactor Failure and Kynurenine Dysregulation.\nAbstract: Glaucoma remains a primary cause of blindness, yet its pathogenesis often extends beyond intraocular pressure (IOP). This review integrates four converging lines of metabolic evidence-aqueous humor (AH) metabolomics, kynurenine pathway (KP) activity, tetrahydrobiopterin (H4BIP) biology, and NAD/one-carbon dysfunction-into a testable framework for retinal ganglion cell vulnerability. By utilizing a systematic AH metabolomics atlas covering glaucoma, pseudoexfoliation, and diabetes on a standardized HILIC-LC-HRMS platform, we demonstrate that, while aromatic amino acid elevations are non-specific markers, kynurenine monooxygenase (KMO) upregulation is a condition-specific glaucoma signature. These local findings are corroborated by systemic evidence: POAG patients exhibit significant folic acid deficiency (p = 0.007) and elevated alpha-1-antitrypsin (AAT). Critically, AAT correlates inversely with both serum folate (rs = -0.485, p < 0.001) and retinal nerve fiber layer thickness (rs = -0.386, p = 0.017), providing the first in-patient evidence linking systemic inflammation to structural optic nerve damage. We conclude that KMO serves as a critical enzymatic node linking tryptophan metabolism, H4BIP availability, and NAD synthesis. These results characterize glaucoma as a disease of progressive cofactor failure and define a research agenda for multimodal metabolic neuroprotection.\n\nID: 42069589\nTitle: Acarbose modulates microglial Pkm2 acetylation to reshape immunometabolism and preserve retinal neurons after ischemia-reperfusion.\nAbstract: Retinal ischemia-reperfusion (IR) elicits microglia-driven neuroinflammation and mitochondrial failure that led to retinal ganglion cell (RGCs) loss, yet effective disease-modifying therapies remain limited. Acarbose (ACA), an \u03b1-glucosidase inhibitor widely used for diabetes, has recently been recognized for its dual regulatory potential on immune metabolism and aging-associated neurodegeneration. Here, we demonstrate that intravitreal ACA administration attenuates retinal inflammation and improves RGCs survival following IR injury. Single-cell RNA sequencing revealed extensive inflammatory activation and metabolic reprogramming across the retina, characterized by enhanced nicotinamide adenine dinucleotide (NAD) catabolism, particularly in microglia. ACA treatment was associated with reversal of these alterations, replenished NAD levels, and restored mitochondrial integrity. Integrative proteomic and biochemical analyses identified pyruvate kinase, muscle-type 2 (Pkm2) as a candidate regulatory node affected by ACA. Intravitreal delivery of siPkm2 partially protected against IR injury, and co-administration with ACA produced an additive trend in neuroprotection. Mechanistically, ACA upregulated sirtuin 1 (Sirt1) and reduced Pkm2 acetylation at lysine 270 (K270), which was linked to pro-inflammatory microglial activation. Structure-based virtual screening further identified HY-113082, a small molecule targeting Pkm2-K270, which synergized with ACA to suppress inflammation and enhance retinal protection. Moreover, Pkm2fl/flCx3cr1-Cre mice conferred partial resistance to IR injury, but blunted the additional benefit of HY-113082 when combined with ACA, consistent with on-target engagement. Our findings support that ACA exerts retinal protection through the Sirt1-Pkm2-NAD axis, suggesting a metabolic checkpoint that integrates immune and mitochondrial regulation. This study provides mechanistic insight into ACA's dual immunometabolic and neuroprotective actions, holding promise for therapeutic insights into neuroinflammation.\n\nID: 42041557\nTitle: Norrin Ameliorates Retinal Ganglion Cell Apoptosis by Normalizing VEGF and PEDF Dysregulation in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy is increasingly recognized as a neurovascular disorder rather than a purely vascular disease; however, therapeutic strategies targeting retinal neurodegeneration remain limited. In this study, we investigated the protective effects of norrin against hyperglycemia-induced retinal neurodegeneration and elucidated its underlying molecular mechanisms in diabetic mice. We found that retinal neurodegeneration may precede microvascular leakage in diabetic retinas. Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Intravitreal supplementation of norrin markedly attenuated hyperglycemia-induced neurodegenerative processes, leading to retinal ganglion cell (RGC) apoptosis, including oxidative stress, inflammation, and neuropathological alterations such as reactive gliosis, glutamate excitotoxicity, and synaptic dysfunction. Norrin also reduced hyperglycemia-induced microvascular leakage and RGC apoptosis by normalizing vascular endothelial growth factor (VEGF) overexpression and restoring pigment epithelium-derived factor (PEDF) levels. Notably, PEDF upregulated by norrin effectively suppressed neurodegenerative processes induced by hyperglycemia or VEGF, thereby preserving RGC function. These findings identify norrin as a critical modulator of hyperglycemia-induced retinal neurodegeneration through restoration of the VEGF-PEDF balance. Our results highlight norrin as a potential therapeutic target for early neurodegenerative changes in diabetic retinopathy.\n\nID: 41998758\nTitle: WFS1 gene delivery rescues visual function in a mouse model of Wolfram syndrome.\nAbstract: Wolfram syndrome is a rare childhood neurodegenerative disease characterized by diabetes followed by severe and rapid optic atrophy leading to blindness before the age of 20. Patients often develop other symptoms, such as deafness and neurological dysfunction. Wolfram syndrome is caused by mutations in the WFS1 gene, which encodes wolframin protein. Despite decades of intensive research, the complex mechanisms of optic neuropathy are not fully understood, and there are currently no therapies to prevent vision loss in Wolfram patients. Here, we showed that the Wfs1 knockout mice produced by the Estonian group, in which exon 8 of the Wfs1 gene was disrupted, exhibit a progressive loss of visual acuity, optic disc pallor and severe optic nerve damage. We tested the efficiency of gene therapy using AAV2 to deliver human WFS1 to retinal ganglion cells in Wfs1 knockout mice. Our results provide the first evidence that intravitreal injection of human WFS1 has significant neuroprotective effects on retinal ganglion cells and their axons and slows the loss of visual acuity. These results demonstrate that WFS1 is able to provide both functional and structural protection to retinal ganglion cells in Wfs1 knockout mice and provide important evidence for the efficacy of WFS1 as a neuroprotective treatment for Wolfram syndrome. These results demonstrate the promising effects of gene therapy for Wolfram syndrome and encourage future research aimed at conducting clinical trials in patients.\n\nID: 41963265\nTitle: Pelargonidin protects retinal ganglion cells in a streptozotocin-induced diabetic rat model by reducing intraocular pressure, suppressing TGF-\u03b2 and activating JAK2/STAT3 signalling pathway.\nAbstract: Diabetic retinopathy (DR) is one of the primary causes of vision impairment, affecting individuals with diabetes, and is marked by the neurodegeneration of the retina along with increased intraocular pressure (IOP). This study sought to determine the effects of pelargonidin on extracellular matrix (ECM) modulation and the inhibition of transforming growth factor-\u03b2 (TGF-\u03b2) and Janus Kinase 2/Signal Transducer and Activator of Transcription 3 (JAK2/STAT3) pathway in retinal ganglion cells of streptozotocin-induced diabetic rats. Male Sprague-Dawley rats (180-200 g) were rendered diabetic by intraperitoneal administration of streptozotocin (STZ). The rats were divided into 5 groups: control, diabetic model (STZ), STZ + low dose pelargonidin (12.5 mg kg-1 per day), STZ + medium dose pelargonidin (25 mg kg-1 per day) and STZ + high dose pelargonidin (50 mg kg-1 per day). IOP was monitored using a tonometer. Whole-mount retinal immunofluorescence staining using RNA-binding protein with multiple splicing (RBPMS) was performed to assess retinal ganglion cell (RGC) density. Protein expression levels of apoptotic markers, ECM components, and TGF-\u03b2 and JAK2/STAT3 signalling pathways were evaluated by Western blotting. Pelargonidin treatment dose-dependently reduced the elevated IOP. Importantly, immunofluorescence analysis revealed a marked dose-dependent preservation of retinal ganglion cell (RGC) density: STZ-induced RGC loss was significantly reversed by pelargonidin, with the highest dose restoring RGC density to near-control or higher levels in both the central and peripheral retina. This was achieved via modulation of apoptosis-related proteins through the upregulation of Bcl-xL, Bcl-2, and downregulation of Bad, Bax and cleaved caspase-3. Furthermore, pelargonidin modulated ECM remodelling protein expression in the RGC layer. In particular, TGF-\u03b22/Smad2/3 signalling was downregulated, and the JAK2/STAT3 pathway was upregulated. By reducing IOP, preserving RGC density, modulating ECM deposition, inhibiting TGF-\u03b2 and upregulating the JAK2/STAT3 pathway, pelargonidin exerts protective effects against diabetic retinal injury. The results of this study further confirm the pharmacological potential of pelargonidin as a therapeutic agent for diabetic retinopathy.\n\nID: 41779109\nTitle: Association and Multimodal Model of Retinal Mid-Peripheral Capillary Free Zones with Structural and Functional Parameters in Diabetic Patients Without Clinical Retinopathy.\nAbstract: To investigate the association between mid-peripheral capillary free zones (CFZs) and retinal structural and functional metrics in diabetics without diabetic retinopathy (DR). This cross-sectional study included 45 eyes from 28 diabetics without DR and 46 eyes from 31 controls (mean age in both groups, 59 years). Macular optical coherence tomography (OCT) scans were acquired for retinal nerve fibre layer (RNFL) and ganglion cell layer thickness measurements. Thickness measurements were obtained using the Early Treatment of Diabetic Retinopathy Study grid. Retinal mid-peripheral CFZs were computed from OCT angiography images using custom MATLAB software. Retinal function was evaluated as a pilot exploratory objective using full-field flash electroretinography. Correlations between mid-peripheral CFZs and retinal structure and function were assessed using linear mixed-effect models, accounting for the association between eyes, while receiver operating characteristic curves were used to compare the multimodal models. Larger periarteriole CFZs were associated with thinner inner inferior RNFL thickness (\u03b2\u2009=\u2009-0.48, p\u2009=\u20090.03) in diabetics without DR. Functionally, there was no significant association between the mid-peripheral CFZs and ERG parameters (p\u2009>\u20090.05) in the no DR group; these findings should be interpreted with caution given the pilot nature of the functional data. The multimodal model of vascular and structural parameters had a modestly improved area under the curve (AUC) and specificity compared to the model of vascular parameters alone (AUC\u2009=\u20090.85 versus 0.83, specificity\u2009=\u20090.65 versus 0.54, respectively). These findings demonstrate that enlarged mid-peripheral periarteriole CFZs are associated with thinner RNFL in diabetics without clinical retinopathy. The multimodal model of vascular and structural metrics showed modestly improved diagnostic ability. This study shows early novel retinal vascular and neural associations in diabetics without clinical retinopathy and demonstrates the potential utility of a multimodal model for discriminating this group from healthy controls.\n\nID: 41750392\nTitle: Glutamate Metabotropic Receptors-Linked Postsynaptic Density Proteins: An Emergent Hub for Antipsychotics' Regulation of Synaptic Plasticity and Metaplasticity.\nAbstract: Glutamate metabotropic receptors (mGluRs) and their molecular partners at the postsynaptic density (PSD) represent a highly dynamic molecular hub that integrates multiple neurotransmitter signals and regulates synaptic plasticity and metaplasticity, which are putatively involved in the pathophysiology of psychiatric illnesses, including schizophrenia. Group I mGluRs (mGluR1 and mGluR5) interact with PSD adaptor and scaffolding proteins, such as Homer, Shank, Norbin, and PICK1, as well as intracellular downstream effectors, creating a molecular network that resembles a Lego-like structure, where modular protein interactions fine-tune glutamatergic transmission. Evidence from preclinical research indicates that dysregulation of mGluR expression and function, along with disrupted PSD protein expression, may contribute to the pathophysiology of schizophrenia by altering glutamatergic neurotransmission and synaptic stability. Antipsychotic mechanisms of action may involve, at least in part, the modulation of mGluR activity mediated through PSD proteins. Notably, novel agents that enhance spinogenesis by acting at the level of PSD proteins, such as SPG302, may open promising avenues for therapeutics aimed at restoring synaptic integrity. While Group I mGluRs dominate postsynaptic regulation, Group II (mGluR2/3) and III (mGluR4/6/7/8) receptors -primarily presynaptic- inhibit neurotransmitter release and plasticity, offering complementary therapeutic avenues. Emerging strategies, such as allosteric modulators of mGluRs, aim to rebalance synaptic signaling in treatment-resistant schizophrenia. This review synthesizes how PSD proteins and mGluRs interact in schizophrenia, exploring their potential as druggable targets for novel therapies.\n\nID: 41554423\nTitle: Resveratrol alleviated diabetic retinal neuronal ferroptosis induced by high glucose through inhibiting HIF-1\u03b1 and HMOX1 pathway.\nAbstract: Diabetic retinopathy (DR) is a common complication of diabetes mellitus that can cause blindness and affect the life quality of patients. Diabetic retinal neurodegeneration (DRN) caused by high glucose might be the earlier pathological change preceding vascular injury. Resveratrol has been showed to have therapeutic effects on DRN but the mechanism remains unclear. Ferroptosis is a new form of regulated cell death and has been found to be involved in DRN. In this study, we found genetic relationship between resveratrol and ferroptosis in DRN pathogenesis using bioinformatics analysis and demonstrated HIF-1\u03b1 and HMOX1 as the hub genes. Our study established in vitro model of DRN in high-glucose cultured SH-SY5Y cells and found ferroptosis processes characterized of reactive oxygen species (ROS) accumulation and cellular mitochondrial damage along with upregulation of HIF-1\u03b1 and HMOX1. Application of resveratrol alleviated high glucose-induced ferroptosis phenotypes in SH-SY5Y cells through inhibiting HIF-1\u03b1 and HMOX1. We also confirmed ferroptosis process and RGC damage in diabetic (db/db) mouse model. The upregulation of HIF-1\u03b1 and HMOX1 was also found in diabetic mouse retina. By resveratrol gavage, RGC damage in diabetic (db/db) mouse model was alleviated and the expression level of HIF-1\u03b1 and HMOX1 in retina was decreased. Our study revealed the involvement of ferroptosis process in retinal neurodegeneration and might provide new insights into neuroprotective interventions in diabetic retinopathy.\n\nID: 41539543\nTitle: Betanin protects against diabetic retinal damage via the inhibition of NF-\u03baB/NLRP3/VEGF axis: Insights from network pharmacology and experimental studies.\nAbstract: Diabetic retinopathy (DIR) is a predominant diabetic microvascular complication that may cause vision loss. Retinal inflammation and angiogenesis contribute largely to the neuronal degeneration in DIR. The current study is aiming to test the effect of oral betanin doses in protection from DIR in rats along with a network pharmacology study to investigate an assumption that betanin may inhibit nuclear factor-\u03ba B (NF-\u03baB). Three rat groups were assigned as vehicle, DIR, and DIR\u00a0+\u00a0Betanin 100\u00a0mg/kg. Molecular docking indicated the possible binding between betanin and NF-\u03baB while the bioinformatic study highlighted a relation between this possible inhibition and suppression of NOD-like receptor pyrin domain-containing protein 3/vascular endothelial growth factor (NLRP3/VEGF) axis. The rat experimental study validated this assumption and indicated a protective effect for betanin on rat retinas as shown by routine hematoxylin and eosin staining (retinal thickness and ganglion cell count) and periodic acid-Schiff staining that was mediated through mitigating expression/protein level for of NF-\u03baB, NLRP3, TNF-\u03b1, IL-6 and VEGF proteins. Immunohistochemistry showed that betanin was able to suppress retinal content of the glial fibrillary acidic protein (GFAP). In conclusion, the current study indicated that betanin was a good candidate for DIR in rats through suppression of the inflammatory cascade and may be suggested for diabetic patients if appropriated clinical studies will be available.\n\nID: 41425077\nTitle: Neuritin: a multifaceted neuroprotective factor with emerging applications for neurodegeneration.\nAbstract: Neuritin is a conserved, activity-regulated gene encoding a glycosylphosphatidylinositol-anchored protein, crucial for neural development, synaptic plasticity, and neuroprotection. Identified via activity-dependent gene screening in the rat hippocampus, neuritin promotes neurite outgrowth, dendritic arborization, and synaptic maturation with neural activity. In this review, we summarize recent findings regarding neuritin's signaling pathways, neuroprotective, neuroregenerative, and neuromodulatory properties, with a focus on its therapeutic potential to counter neurodegeneration in various conditions such as glaucoma, Alzheimer's disease, stroke, diabetic neuropathy, and neuropsychiatric disorders. Additionally, recent studies reveal roles in immunoregulation, angiogenesis, and cancer biology, highlighting neuritin as a versatile signaling molecule with broad therapeutic implications.\n\nID: 41419594\nTitle: Longitudinal changes in each retinal layer thickness in diabetic retinopathy patients treated with pan-retinal photocoagulation.\nAbstract: To identify longitudinal changes in each retinal layer thickness in diabetic retinopathy (DR) patients who underwent pan-retinal photocoagulation (PRP). The subjects were divided into three groups: type 2 diabetes patients without DR (DM group), those with DR (DR group), and those who underwent PRP\u2009\u2265\u20096 months earlier (PRP group). Following the baseline visit, patients underwent three additional assessments at 1-year intervals. In total, 297 eyes were included: 87, 124, and 76 in the DM, DR, and PRP groups, respectively. The baseline ganglion cell complex (GCC) thickness was 110.4\u2009\u00b1\u200913.4, 112.5\u2009\u00b1\u200913.2, and 116.1\u2009\u00b1\u200917.6\u2009\u03bcm in the DM, DR, and PRP groups, respectively (P\u2009=\u20090.047). The baseline thickness of inner nuclear layer (P\u2009=\u20090.026) and outer plexiform layer (P\u2009=\u20090.002) differed significantly, which was significantly thicker in the PRP group. The photoreceptor layer and retinal pigment epithelium thicknesses differed significantly among the groups (both P\u2009<\u20090.001), and those in the PRP group were significantly thinner than in the other groups. In the PRP group, there were significant decreases in GCC and outer nuclear layer (ONL) thickness over time, while the other layers did not change significantly. The GCC (estimate\u2009=\u2009-0.15, P\u2009=\u20090.012) and ONL (estimate\u2009=\u2009-0.16, P\u2009=\u20090.019) thicknesses were significantly associated with changes in best-corrected visual acuity. The thickness of each retinal layer of patients who underwent PRP changed differently over time, and these changes were significantly associated with changes in visual acuity.\n\nID: 41411089\nTitle: Optic Atrophy Predominant WFS1 Disorder-A Case-Control Study.\nAbstract: Wolfram syndrome type 1 (WS1), or \"DIDMOAD\" (diabetes insipidus, diabetes mellitus, optic atrophy (OA), and deafness, OMIM #222300), is a rare neurodegenerative disorder resulting from homozygous, compound heterozygous autosomal recessive (AR), or rarely autosomal dominant mutations in the WFS1 gene. Isolated OA with adult-onset, milder phenotypes in WS1 is rare and typically associated with biallelic AR mutations. We describe 7 patients of pauci-syndromic WS1 presenting with adult-onset OA and compare parameters of visual function with other OA-predominant syndromes. A retrospective review was performed identifying records of patients seen at our institution from January 1, 2020, through December 31, 2024, who were found to have OA secondary to mutations in OPA1 (n = 9), WFS1 (n = 7), POLG (n = 3), mutations causing Leber hereditary optic neuropathy (LHON) (n = 17) or isolated OA from other genetic causes (n = 7). Patients were excluded who harbored confounding causes of vision loss and nongenetic causes of OA. Clinical data of visual function were recorded, including mean deviations and foveal sensitivities on automated visual fields (AVF), and ganglion cell complex (GCC) and peripapillary retinal nerve fiber layer (RNFL) thickness on optical coherence tomography (OCT). Visual acuities from initial neuro-ophthalmology consultation were recorded in logMAR format. Statistical analysis was performed on continuous variables. This study was granted exempt status by our institutional IRB. Compared with other OA syndromes, patients with LHON had the most severe average AVF and foveal sensitivity depressions and the lowest presenting logMAR acuity. Patients with WS1 in our cohort had significantly later onset of symptoms and delayed presentation compared with other OA syndromes. Patients with WS1 were significantly more likely to present with arcuate scotomas compared with other genetic OA syndromes, while patients with LHON and patients with OPA1 mutations (autosomal dominant optic atrophy [ADOA]) presented commonly with central scotomas and blind spot enlargement, respectively. WS1 diagnosis was not significantly associated with any specific pattern of thinning on OCT of the RNFL or GCC. ADOA diagnosis was associated with the most peripapillary RNFL thinning overall of all OA syndromes, most significantly in the superior and inferior quadrants. Our cohort of patients with WS1 showed uncharacteristically mild vision loss and minimal syndromic features, suggesting that a milder alternative phenotype with WFS1 mutations is possible in contrast to the traditional DIDMOAD syndrome. Compared with other OA syndromes, these patients with WS1 showed significant associations with arcuate visual field defects and trends toward superior/inferior peripapillary RNFL thinning. This suggests that relative preservation of papillomacular bundle fibers and thus milder central visual acuity loss may be a unifying feature in their phenotype. This series expands the clinical spectrum of WS1 and should encourage further work to study the pathogenic role of wolframin in vision loss. Clinicians should consider Wolfram syndrome in cases of adult-onset, symmetric, near-isolated OA, especially in cases with arcuate field defects, which are more commonly seen than in other genetic syndromes.\n\nID: 41294828\nTitle: Autophagy Impairment in Retinal Ganglion Cells Following Hypoglycemia in Mice.\nAbstract: (1) Background: Diabetic retinopathy (DR), caused by hypo- and hyperglycaemia, is the leading cause of blindness. Hypoglycemia induces endoplasmic reticulum stress and retinal cell death in mice, and low-glucose conditions induce macroautophagy/autophagy defects in 661W photoreceptor cells and retinal explants. Very few studies have analyzed the effect of hypoglycemia on retinal autophagy, so we decided to fill this gap. (2) Methods: We use C57BL/6 and GFP-LC3 mice and isolated retinal ganglion cells (RGCs) from both mouse models to study the autophagy process. (3) Results: Intraocular injection of rapamycin and 5 h hypoglycemia showed an increase in autophagosomes formation, specifically in the RGCs. Isolated GFP-LC3 RGCs showed an increase in autophagosome formation under low-glucose conditions. In contrast, infection of isolated C57BL/6 RGCs with the RFP-GFP-LC3 lentivirus revealed a defect in autophagosome/lysosome fusion under these conditions. (4) Conclusions: This study showed that 5 h hypoglycemia induces autophagosomes formation in mouse RGCs; however, a defect in the fusion process inhibits the protective effect of autophagy. Therefore, modulating both autophagic and apoptotic pathways might be important to avoid complications associated with DR.\n\nID: 41237937\nTitle: Inhibition of serine racemase prevents retinopathy in diabetic mice.\nAbstract: A single-nucleotide polymorphism in the serine racemase (SRR)-encoding gene, Srr, is associated with an increased risk of type 2 diabetes. Studies, including our own, demonstrate that SRR is linked to a complication of diabetes, diabetic retinopathy (DR), and deletion of Srr protects diabetic animals from developing retinopathy. We investigate the feasibility and mechanisms of SRR inhibition as a strategy to prevent DR. SRR proteins in the retinas of db/db mice were approximately 50\u00a0% higher than C57BLKS/J wild-type (WT) mice, while D-serine levels in the aqueous humor were more than two-fold higher. Oral gavage of l-aspartic acid \u03b2-hydroxamate (L-ABH) improved b-wave amplitudes in electroretinogram recordings under both photopic and scotopic conditions. It also protected the inner retina in db/db mice by reducing the loss of retinal ganglion cells, endothelial cells, and pericytes, as well as decreasing the activation of M\u00fcller cells. In high glucose and hypoxia, interleukin-1 and interleukin-18 mRNA levels were lower in Srr-deleted M\u00fcller cell cultures than in WT cultures. Intravitreal injection of L-ABH mitigated glutamate-induced neurotoxicity in the retina. Systemically, L-ABH maintained euglycemia and improved glucose tolerance in db/db mice by inhibiting liver gluconeogenesis through restricting the expansion of pancreatic islet \u03b1-cells. Altogether, our results demonstrate that SRR inhibition prevents retinopathy in diabetic animals by blocking excitotoxicity and M\u00fcller cell-mediated inflammation in the retina, while also maintaining glucose homeostasis. This is the first demonstration that pharmacological blockade of SRR improves retinopathy and normalizes glucose levels in a type 2 diabetes model.\n\nID: 41137890\nTitle: Ginkgo Biloba extract attenuates diabetic retinopathy progression by modulating TP53 ubiquitination in a rat model.\nAbstract: Diabetic retinopathy (DR) is a microvascular complication of diabetes characterized by damage to the retina's neurons and blood vessels. Ginkgo biloba extract (GBE) has demonstrated neuroprotective properties, however, its specific mechanisms in DR remain incompletely understood. This research aims to elucidate the underlying mechanisms of GBE in DR. A diabetic rat model was induced with streptozotocin (STZ) and divided into control, diabetic, and GBE-treated groups. Retinal tissues of each group were analyzed using histology, TUNEL staining, and immunofluorescence. Bioinformatics identified potential GBE targets for DR, and protein-protein interaction network analysis prioritized core targets. Western blot and immunoprecipitation assays were used to detect protein expression and ubiquitination status. We successfully constructed the DR rat models and observed that GBE intervention effectively reverses diabetes-induced hyperglycemia and mitigates retinal ganglion cell (RGC) damage in the DR rat model. TUNEL staining indicates GBE's protective role against RGC apoptosis induced by DR. Bioinformatics identified 135 GBE targets in DR, with a focus on apoptosis pathways. Critically, we demonstrated an upregulation of TP53 expression in the retinal tissues of the DR rat model, an effect that was successfully reversed following GBE intervention. Notably, GEB increased TP53 ubiquitination, suggesting a potential modulation of TP53 stability and function. GBE attenuates DR progression by modulating TP53 ubiquitination in a rat model. The findings highlight the potential therapeutic benefits of GBE in DR and suggest further investigation into its mechanisms and broader bioactivity pathways.\n\nID: 41130930\nTitle: To ac tap or not to ac tap: Multi-centre outcomes of patients receiving anti-VEGF injections.\nAbstract: PurposeTo compare intraocular pressure (IOP) and retinal nerve fibre layer (RNFL) thickness in patients receiving intravitreal anti-vascular endothelial growth factor (VEGF) injections with and without anterior chamber paracentesis (ACP).MethodsThis multicentre retrospective cohort study included 269 injection-na\u00efve eyes from 210 patients with neovascular age-related macular degeneration (AMD) or diabetic macular oedema (DME). A matched subset of 140 eyes (70 with ACP, 70 without) was selected based on age, sex, diagnosis, laterality, and number of injections. RNFL thickness (overall and by quadrant) was measured at baseline and one-year follow-up. Additional outcomes included IOP, visual acuity (VA), and central retinal thickness (CRT).ResultsThe matched cohort had a mean age of 71.06\u202f\u00b1\u202f11.44 years, with 61.4% female participants. ACP eyes had worse baseline VA, higher IOP, and thicker CRT (p\u2009<\u20090.050, for all), but showed greater VA improvement (p\u2009=\u20090.023) and a trend towards greater CRT reduction (p\u2009=\u20090.061). RNFL thinning over one year did not differ between the groups (-3.24\u2009\u00b1\u200911.82\u2005\u00b5m vs -2.95\u2009\u00b1\u20097.81\u2005\u00b5m, p\u2009=\u20090.883). No major complications were observed.ConclusionACP did not significantly reduce RNFL thinning over one year but was well tolerated. It may be considered in patients at higher risk from transient IOP elevations. Future prospective studies are warranted to clarify its role in specific patient subgroups.\n\nID: 41101191\nTitle: Thickness profile of the ganglion cell complex and choroid in patients with persistent diabetic macular edema.\nAbstract: About 40\u00a0% of patients with diabetic macular edema (DME) do not respond optimally to first-line treatment with intravitreal injection of anti-vascular endothelial growth factor (AVEGF). Evidence suggests that additional vascular and neurodegenerative mechanisms may be involved. This study aimed to characterise the thickness of the Ganglion Cell Complex (GCC) and investigate the Choroidal Vascularity Index (CVI) in patients with different patterns of therapeutic response to AVEGF DME. This cross-sectional study included 27 diabetic patients into 3 different groups based on their response to AVEGF therapy: control group, responder DME group, and persistent DME group. The study's approach to vascular and neurodegenerative imaging biomarkers involved three steps: (1) Automatic quantification of GCC thickness, with manual correction when necessary; (2) Semi-automatic measurement of choroidal thickness; and (3) Analysis of choroidal area and choroidal luminal area using ImageJ software to calculate the CVI. In the overall characterization of the sample, a significant difference was observed only in the Best Corrected Visual Acuity (BCVA). There was a significant difference in Average Retinal Thickness (1\u00a0mm, 3\u00a0mm, and 6\u00a0mm) between the 3 groups and in GCC thickness at 1\u00a0mm. BCVA was negatively correlated with mean retinal thickness, while CVI showed a potential positive correlation with BCVA. While demographic and general clinical characteristics showed minimal differences across the groups, important differences in GCC and choroidal characteristics were observed. GCC (1\u00a0mm) may be interesting to explore in predicting visual outcomes after treatment, and CVI may impact visual gain.\n\nID: 41024545\nTitle: Role of Macular Ganglion Cell Complex Analysis for Diagnosis of Glaucoma Using Spectral Domain Optical Coherence Tomography.\nAbstract: Glaucoma is chronic progressive irreversible optic neuropathy characterized by significant visual field (VF) loss. So, early diagnosis and proper treatment can preserve the useful vision in lifetime. The objective of the study was to determine the importance of ganglion cell complex (GCC) analysis as a parameter for diagnosis of glaucoma. This case control study was conducted in the Department of Ophthalmology, Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) General Hospital, Bangladesh over a period of one year from July 2017 to June 2018. Twenty five (25) Type-2 Diabetes control subjects and 50 subjects with Type-2 diabetes were divided into two groups, 25 diabetic with pre perimetric and 25 diabetic with perimetric glaucoma. In this study, there was no significant difference in age (50.92\u00b15.53 years vs. 52.44\u00b14.75 years vs. 52.64\u00b17.80 years), gender. Regarding Optical coherence tomography (OCT) Retinal Nerve Fiber Layer (RNFL) of right eyes of the study subjects, superior and inferior RNFL were significantly thinner in both pre-perimetric right eye (109.18\u00b18.95 and 111.21\u00b110.53) and perimetric right eye (90.28\u00b18.94 and 91.51\u00b17.87) comparing normal eyes (129.12\u00b12.68 and 132.17\u00b13.22). Superior and inferior RNFL were significantly lower in both pre-perimetric (110.13\u00b111.53 and 113.75\u00b19.61) and perimetric (95.93\u00b115.08 and 93.29\u00b112.68) left eyes comparing normal left eyes (129.71\u00b15.50 and 132.57\u00b15.22). Regarding OCT GCC layer of right eyes of the study subjects, superior and inferior GCC layer were significantly lower in both pre-perimetric (87.66\u00b13.81 and 89.70\u00b14.98) and perimetric (77.48\u00b16.97 and 79.21\u00b16.06) right eyes comparing normal eyes (104.53\u00b12.73 and 106.88\u00b13.29). Regarding OCT GCC layer of left eyes of the study subjects, superior and inferior GCC layer were significantly lower in both pre-perimetric (84.88\u00b13.82 and 87.21\u00b13.77) and perimetric (81.08\u00b19.51 and 80.01\u00b110.02) left eyes comparing normal eyes (102.64\u00b12.29 and 105.20\u00b11.27). GCC parameter is useful tool for diagnosis of Glaucoma. It has same ability to discriminate eyes with glaucoma and non glaucomatous eyes compared to RNFL. In glaucoma, GCC layer is significantly thin which correlates strongly with glaucomatous damage. According to our result GCC layer analysis is important investigation to diagnosis of Glaucoma.\n\nID: 41002420\nTitle: The Form and Function of Retinal Ganglion Cells in Diabetes.\nAbstract: This review examines how diabetes affects the ganglion cells of the retina, including the axons that make up the optic nerve. Links between established changes in the morphology of retinal ganglion cells (RGCs) and vision loss, as well as other functions, such as the pupillary light reflex, are considered. RGC morphology and function are significantly altered in both animal models and humans with diabetes. Diabetes affects all parts of the RGC, including the dendrites, the cell body, the axons making up the nerve fiber layer, and the optic nerve. Subtypes of RGCs appear to be affected differently by diabetes, and the morphology and electrophysiological output are more significantly affected in ON-RGCs than in OFF cells, which may explain part of the mechanism underlying the widely documented diabetes-induced reduction in contrast sensitivity. Furthermore, the morphology of the specialized light-sensitive melanopsin-containing RGCs also appears to be affected by diabetes, which may explain deficits in circadian rhythm and the pupillary light reflex. Potential therapeutic approaches aimed at protecting RGCs in diabetes are also discussed. Overall, strong evidence supports the conclusion that diabetes impacts the form and function of RGCs and their axons within the optic nerve, resulting in deficient regulation of circadian rhythms and the pupillary light reflex, in addition to vision.\n\nID: 40976316\nTitle: Longitudinal Neural and Microvascular Changes in Type 2 Diabetic Patients Without Retinopathy: A 2-Year Prospective Cohort Study.\nAbstract: To compare the 2-year longitudinal changes in macular ganglion cell-inner plexiform layer thickness (GCIPLT) and superficial capillary plexus (SCP) vessel density between patients with type 2 diabetes mellitus (T2DM) without retinopathy (non-DR) and healthy controls. Prospective observational cohort study. T2DM patients without clinical retinopathy at baseline and after a 2-year follow-up, along with age- and sex-matched healthy controls, were recruited from the community in Guangzhou, China. Measurements of macular GCIPLT, retinal thickness (RT), and SCP vessel density were conducted at baseline and at the 2-year follow-up. Linear mixed-effects models were used to estimate absolute and relative rates of changes and to compare absolute rates between the 2 groups. A total of 282 eyes (141 in the control group and 141 in the non-DR group) were included in the analysis. Significant reductions in GCIPLT and GCIPLT/RT occurred only in the non-DR group, with GCIPLT decreasing by -0.229 \u00b5m/y (95% CI = -0.313 to -0.144; P < .001) and 0.324 % (95% CI = 0.444 to 0.204; P < .001), approximately 5-fold faster than in the control group. After adjusting for confounding factors, the longitudinal rates of RT, GCIPLT, and GCIPLT/RT were significantly accelerated in the non-DR group compared to the control group by -0.603 \u00b5m/y (95% CI = -0.939 to -0.268; P < .001), -0.189 \u00b5m/y (95% CI = -0.306 to -0.073; P = .001), and -0.073 % (95% CI = -0.118 to -0.028; P = .001), respectively. Although longitudinal changes in SCP vessel density did not show significant differences between the 2 groups (P = .861). Our findings suggest that neurodegenerative changes may precede microvascular alterations in non-DR patients, indicating that monitoring of GCIPLT is crucial for patients with long-standing diabetes, even in the absence of retinopathy.\n\nID: 40971499\nTitle: Comparative analysis of retinal thickness between type 1 and type 2 diabetes mellitus patients with similar disease duration: A cross-sectional study.\nAbstract: To assess the retinal thickness in patients with type 1 diabetes mellitus (T1DM) and type 2 DM (T2DM) of equal disease duration, comparing them with age- and sex-matched healthy controls. This cross-sectional, comparative, and observational study included 96 participants, categorized into four groups: A1 (patients with T1DM, n = 24), A2 (age- and sex-matched nondiabetic controls for A1, n = 24), B1 (patients with T2DM, n = 24), and B2 (age- and sex-matched nondiabetic controls for B1, n = 24). Evaluations included retinal nerve fiber layer (RNFL) thickness, ganglion cell complex (GCC) thickness, central macular thickness (CMT), visual acuity, color vision, and contrast sensitivity. The primary objective was to compare RNFL, GCC, and CMT between T1DM and T2DM patients with equivalent disease duration and their respective controls. Secondary analyses assessed differences in visual acuity, color vision, and contrast sensitivity between T1DM and T2DM patients. The mean age of T2DM patients was 50.96 years, and for T1DM patients it was 28.96 years. T2DM patients exhibited significant GCC reduction in the superonasal ( P = 0.046) and inferonasal quadrants ( P = 0.048) compared to T1DM. T2DM also showed significant RNFL thinning in the superior ( P = 0.037), inferior ( P = 0.012), and temporal quadrants ( P = 0.025) compared to T1DM after adjustment for age and DM duration. No significant difference in CMT was observed between T1DM and T2DM. In T1DM patients, mean best-corrected visual acuity was significantly worse than that of controls ( P = 0.019). Contrast sensitivity and color vision did not differ significantly between T1DM and T2DM. This study reveals earlier RNFL and GCC thinning in T2DM compared to T1DM.\n\nID: 40967391\nTitle: SPG302 protects retinal ganglion cells and preserves visual function by preserving synaptic activity in a mouse model of glaucoma.\nAbstract: Glaucoma, a leading cause of irreversible vision loss worldwide, is an optic neuropathy characterized by optic nerve degeneration and retinal ganglion cell (RGC) death. Early glaucomatous damage is often associated with dendritic and synaptic abnormalities in RGCs, yet the mechanisms linking these synaptic alterations to RGC death remain unclear. In a mouse model of glaucoma, treatment with the clinical-stage, synaptogenic small molecule SPG302, a pegylated benzothiazole derivative, demonstrated neuroprotective effects, protecting RGCs and their axons in the glaucomatous retina and also improving retinal function as assessed by pattern electroretinogram testing. Elevated intraocular pressure disrupted synapses, as evidenced by reduced synaptophysin expression and homeostatic increases in Bassoon and PSD95 levels in the inner plexiform layer. SPG302 treatment effectively preserved synaptic integrity by reversing these changes. These findings highlight the therapeutic potential of SPG302 for protecting RGCs and preserving vision by modulating synaptic activity in glaucomatous neurodegeneration.\n\nID: 40939765\nTitle: Retinal neurodegeneration and choroidal changes of early diabetes in peripapillary region detected by swept-source optical coherence tomography angiography.\nAbstract: This study was designed to evaluate peripapillary retinal nerve fiber layer (pRNFL) and choroidal alterations in diabetic patients without diabetic retinopathy (NDR), and further explore their association utilizing ultrawide-field swept-source optical coherence tomography angiography (UWF-SS-OCTA). This cross-sectional study included 169 eyes of 169 NDR subjects and 54 eyes of 54 healthy controls. pRNFL, choroidal thickness and volume were compared and measured with UWF-SS-OCTA. The association between pRNFL and choroidal parameters was assessed with Spearman correlation analysis. Further multivariate linear regression analysis was performed to evaluate their relationship after adjusting for confounding factors. Compared with healthy controls, NDR patients showed reduced choroidal thickness and volume in the full range and several peripapillary subfields, while a statistical decrease of pRNFL was only detected in the inferior quadrant (P\u00a0=\u00a00.04). Regarding the distribution profiles in the peripapillary region, the choroid was thickest in the temporal region and thinnest in the inferior region, and a more prominent decrease compared with controls was found in the inferior region. Average pRNFL thickness was independently associated with full-range mean choroidal volume in multiple regression analysis (\u03b2\u00a0=\u00a00.16, P\u00a0=\u00a00.04). As two early signs of DR, choroidal thinning could precede retinal neurodegeneration. Decreased choroidal thickness may account for the susceptibility of RNFL thinning.\n\nID: 40833325\nTitle: Differential Expression of the Synapse Regulatory Proteins Neurexins in Early Diabetic Retinal Disease.\nAbstract: Neurexins (NRXNs), a complex family of synapse regulatory proteins, represent attractive candidate molecular mediators of retinal neuronal dysfunction in early diabetic retinal disease (DRD) given their roles in the central nervous system and recent work suggesting a potential link with diabetes mellitus (DM). As antibodies are unable to distinguish NRXN family members and isoforms, the purpose of this study was to investigate differential expression of individual NRXN transcripts in relevant retinal cell types in early DRD. RNAscope multiplexed fluorescent in situ hybridization was used to quantify transcripts of NRXNs in mouse and human retina. DM was induced in C57BL/6J mice using streptozotocin (STZ) and the retinal phenotype characterized by electroretinogram (ERG), optical coherence tomography (OCT), and optokinetic tracking (OKT) after 6 weeks. Retinal ganglion cells (RGCs) were generated in vitro by directed differentiation from human embryonic stem cells (hESCs), cultured in normal or high glucose, and NRXN expression assessed by qPCR and Western blot. All NRXN family members (NRXN1, NRXN2, and NRXN3) were enriched in inner retinal neurons in both human and mouse tissue. We identified decreased Nrxn3 transcripts, specifically the Nrxn3\u03b2 isoform, in RGCs of diabetic mice at 6 weeks after STZ treatment. Interestingly, Nrxn3\u03b1 and Nrxn3\u03b2 were differentially expressed in inner retinal layers. Finally, we confirmed decreased Nrxn3\u03b2 expression in hESC-RGCs cultured in high glucose in vitro. Our findings suggest that NRXNs may play cell-type-specific roles in the inner retina and associate decreased Nrxn3\u03b2 expression in RGCs with inner retinal dysfunction in early DRD.\n\nID: 40794319\nTitle: HuD and alpha-crystallin A axis protects neuro-retinal cells in early diabetes.\nAbstract: Diabetic retinopathy (DR) is a prevalent microvascular complication of diabetes; however, neuro-retinal degeneration is also observed in patients with diabetes without signs of DR. The mechanisms leading to neuro-retinal cell loss before vascular complications manifest in diabetes remain poorly understood. In this study, we investigated the neuronal RNA-binding protein HuD as a novel regulator of neuro-retinal degeneration in the early stage of diabetes. We determined the expression of HuD and alpha-crystallin A (CRYAA) in the retinal ganglion cell layer. HuD and CRYAA were down-regulated in the retinas of streptozotocin-induced diabetic rats and in neuro-retinal cells (R-28) treated with high glucose. Cryaa mRNA was identified as a novel target transcript of HuD, and we demonstrated that HuD post-transcriptionally regulates the expression of Cryaa mRNA by binding to its 3'-untranslated region. Silencing and overexpression of HuD positively regulated the expressions of Cryaa mRNA and protein. We demonstrated that the increase in inflammatory cytokines such as TNF\u03b1, IL-1\u03b2, and IL-6 in R-28 cells under hyperglycemic conditions was a result of both CRYAA and HuD levels. Silencing HuD and CRYAA enhanced high glucose-induced R-28 cell death, whereas their overexpression alleviated this effect. HuD post-transcriptionally regulates CRYAA expression, influencing the function and viability of neuro-retinal cells under diabetic conditions. Our results suggest that the HuD/CRYAA axis plays a crucial role in neuro-retinal cells and has the potential to serve as a prognostic factor and therapeutic target for diabetic neuro-retinal degeneration.\n\nID: 40763825\nTitle: Hyaluronic acid methacryloyl-based co-delivery system for aflibercept and miR-21-3p antagomir: a dual-therapeutic approach for diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss characterized by concurrent retinal vascular dysfunction and neurodegeneration. While current therapies primarily target vascular dysfunction, they offer limited neuroprotective benefits. In this study, we developed a novel light-responsive hydrogel composed of hyaluronic acid methacryloyl (HAMA) for the co-delivery of aflibercept and miR-21-3p antagomir (HAMA@(Ab+M21A)). This dual-therapeutic strategy was designed to concurrently target retinal vascular dysfunction and neurodegeneration. Upon light exposure, HAMA hydrogel undergoes rapid in situ crosslinking, exhibiting excellent ocular biocompatibility and sustained drug release over 45\u00a0days, in parallel with controlled biodegradation. HAMA@(Ab+M21A) effectively inhibits VEGF-induced vascular dysfunction, suppresses reactive gliosis, and promotes retinal ganglion cell survival in vitro and in vivo. Collectively, this study demonstrates the therapeutic potential of HAMA@(Ab+M21A) as a dual-function strategy for DR, providing both anti-angiogenic and neuroprotective effects to impede disease progression.\n\nID: 40759398\nTitle: MiRNA-122-5p promotes retinal ganglion cell oxidative damage by targeting DJ-1 in hyperglycemic retina.\nAbstract: Mitochondrial dysfunction, induced by prolonged hyperglycemia, is widely regarded as a central factor in oxidative stress and retinal ganglion cell (RGC) degeneration in diabetic retinopathy (DR). DJ-1 (PARK7) acts as a crucial antioxidant defense mechanism, stabilizing mitochondrial structure and redox balance. However, its expression is dramatically suppressed under diabetic conditions, and the upstream regulatory mechanisms remain incompletely characterized. Growing evidence from epigenetic research implicates microRNAs (miRNAs) as important players in the molecular pathways underlying DR progression. Among these, miRNA-122-5p has drawn increasing attention due to its aberrant activity under diabetic stress and its putative interaction with PARK7. In this study, we employed a streptozotocin-induced type 1 diabetes mouse model and glucose-stimulated R28\u00a0cells to explore the contribution of miRNA-122-5p to mitochondrial damage, oxidative stress, and RGC injury. In diabetic mice, we observed significant oxidative imbalance, increased apoptotic activity, RGC loss, and diminished retinal function. MiRNA profiling identified miRNA-122-5p as the most upregulated among candidate miRNAs. Inhibition of miRNA-122-5p attenuated these pathological changes and preserved both cellular integrity and visual function. In vitro, high glucose triggered mitochondrial fragmentation, membrane potential collapse, and excessive reactive oxygen species generation in R28\u00a0cells. Suppressing miRNA-122-5p alleviated these injuries. Dual-luciferase assays confirmed that miRNA-122-5p directly targets PARK7, thereby post-transcriptionally repressing DJ-1 expression and compromising mitochondrial resilience. These findings establish miRNA-122-5p as a critical upstream regulator of DJ-1-mediated antioxidant defense. By aggravating mitochondrial oxidative stress, it contributes to RGC vulnerability in DR. Targeted modulation of miRNA-122-5p may offer a novel therapeutic approach to preserve retinal neurons and counteract neurodegeneration in DR.\n\nID: 40639562\nTitle: Protective effects of empagliflozin against NMDA-induced excitotoxicity in the rat retina.\nAbstract: Empagliflozin (EMPA), a sodium-glucose cotransporter 2 inhibitor used in patients with type 2 diabetes, exerts various beneficial effects, including anti-inflammatory and antioxidant properties, in addition to its glucose-lowering effect. In this study, we examined whether EMPA protects against N-methyl-d-aspartic acid (NMDA)-induced retinal excitotoxicity and the mechanisms underlying its protective effects. Male Sprague-Dawley rats (7-8\u00a0weeks old) were used in this study. The number of cells in the ganglion cell layer (GCL) decreased 7\u00a0days after intravitreal injection of NMDA (50\u00a0nmol). Simultaneous intravitreal injection of EMPA (50 and 100\u00a0nmol) and NMDA reduced NMDA-induced cell loss in a dose-dependent manner. The protective effect of EMPA was significantly attenuated by the AMP-activated protein kinase (AMPK) inhibitor, compound C (10\u00a0nmol). NMDA increased the number of terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive cells in the GCL 6\u00a0h after injection, and the response was significantly, but not completely, attenuated by EMPA. These results suggest that EMPA protects against NMDA-induced retinal excitotoxicity in rats. The protective effect of EMPA may be partly attributed to the activation of the AMPK pathway and inhibition of neuronal cell apoptosis.\n\nID: 40607869\nTitle: Diabetes-Induced Dysregulation of Peripapillary and Macular Neurovascular Units.\nAbstract: The aim of this study was to investigate the impact of diabetic retinopathy (DR) on macular and peripapillary neurovascular units (NVUs) by assessing optical coherence tomography (OCT)/OCT angiography-based macular and peripapillary NVU parameters. This study enrolled 182 eyes with type 2 diabetes mellitus (DM) eyes and 202 healthy control eyes. The eyes of DM patients were divided into DM without DR (DM/noDR; n = 136) and DR stage groups (n = 46). Macular NVU parameters consisted of ganglion cell-inner plexiform layer (GCIPL) thickness and macular perfusion density (PD). As for peripapillary NVU parameters, peripapillary retinal nerve fiber layer (RNFL) thickness, together with radial peripapillary capillary perfusion density (RPC-PD) and RPC flux index (RPC-FI), represented by peripapillary structural and functional vascular parameters, were also examined. Macular and peripapillary parameters were compared among three stages, and correlations between macular and peripapillary parameters were examined for each stage. Macular GCIPL thickness and macular PD decreased with stage progression, preserving positive correlations (i.e., preserving macular NVU) with each other in all eyes, but correlation coefficients were the lowest in DM/noDR eyes. Macular GCIPL thickness, as well as macular PD, positively correlated with peripapillary NVU parameters over the entire stages except macular PD and RNFL thickness in DR eyes (i.e., preserving macular and peripapillary NVU), but correlation coefficients were the lowest in DM/noDR eyes. Macular and peripapillary NVU were preserved throughout the stages: control, DM/noDR, and DR groups, but the linkage weakened at the onset of DM, suggesting diabetes-induced dysregulation of macular and peripapillary NVUs in subclinical DR.\n\nID: 40535992\nTitle: Longitudinal Association of Decreased Serum Uric Acid Level with the Thinning of Ganglion Cell Inner Plexiform Layer Thickness in Chinese Adults with Type 2 Diabetes Mellitus without Retinopathy.\nAbstract: To explore the associations between serum uric acid (SUA) level change and changes in the retinal neurodegenerative biomarkers in type 2 diabetes mellitus patients without retinopathy. This is a prospective observational cohort study based on the baseline and 1-year follow-up data of the Guangzhou Diabetic Eye Study. Type 2 diabetes mellitus patients without retinopathy were recruited. Thicknesses of ganglion cell inner plexiform layer (GC-IPL) and peripapillary retinal nerve fiber layer (pRNFL) were measured via swept-source optical coherence tomography. The associations between SUA level change and the thinning rates of GC-IPL and pRNFL were analyzed using multivariate linear regression analysis. Sub-group analysis based on sex was constructed. A total of 1084 participants were enrolled in our study. After adjustment, both male and female patients with decreased SUA levels in higher baseline SUA level group had a significantly slower thinning rate of GC-IPL than those with non-decreased SUA levels. In higher baseline SUA level with decreased SUA level group, male patients exhibited significantly slower thinning rate of inferior GC-IPL, while female patients exhibited significantly slower thinning rate of inferior and nasal GC-IPL and inferior pRNFL, when compared to those with non-decreased SUA levels. Our findings prove that decreased SUA level is associated with a slower GC-IPL thinning rate in higher baseline SUA level group, suggesting that decreased SUA level could be constituted as a potential future control target to delay the neurodegeneration in type 2 diabetes mellitus patients.\n\nID: 40464812\nTitle: RBM15 promotes m6A methylation and stability of KLF6 mRNA to accelerate pyroptosis of retinal ganglion cells in early-stage diabetic retinopathy.\nAbstract: Neurodegeneration in early-stage diabetes retinopathy (DR) is mainly caused by the loss of retinal ganglion cells (RGCs), and high glucose-treated cell pyroptosis contributes to an important cause. However, the detailed molecular regulatory mechanism has not yet been thoroughly examined. In this study, primary mouse RGCs were stimulated with different concentrations of glucose, and mouse was intraperitoneally injected with streptozotocin (STZ) to construct DR model in vitro and in vivo. We found that compared to normal controls, RNA binding motif protein 15 (RBM15) was significantly upregulated in high glucose-treated RGCs and STZ-induced mice. RBM15 silence restored cell viability and inhibited cell apoptosis and cell death in high glucose-triggered RGCs. In parallel, RBM15 knockdown distinctly improved pathological damage such as thinning of retinal tissue thickness and loss of RGCs in STZ-modeling mice. Interestingly, the production of inflammatory cytokines and the expression of Cleaved caspase-1, NLRP3 and GSDMD-N were significantly reduced by RBM15 silence in vivo and in vitro. Mechanistically, RBM15 bound to kruppel like factor 6 (KLF6) mRNA to promote m6A modification and stabilize KLF6 mRNA, upregulating KLF6 expression in model cells and model mice retinal tissues. KLF6 overexpression increased the production of inflammatory cytokines and the expression of proteins related to pyroptosis, reversing the protective effects of RBM15 silence in high glucose-treated RGCs and diabetic retina. In conclusion, RBM15 is upregulated by high glucose, and stabilizes KLF6 mRNA to activate NLRP3-mediated pyroptosis pathway, exacerbating inflammation and apoptosis of RGCs and accelerating the progression of DR.\n\nID: 40451313\nTitle: MiR-29a-5p engages in the mechanism of diabetic retinopathy by specifically targeting SIRT3.\nAbstract: Whether miR-29a-5p is associated with Diabetic Retinopathy (DR) is still a subject of ongoing discussion. The current research examines the involvement of miR-29a-5p in regulating apoptosis, oxidative stress, and inflammation of retinal ganglion cells (RGCs) generated by High Glucose (HG). Additionally, we are interested in analyzing the contribution of miR-29a-5p in DRdeveloping. We obtained peripheral blood samples from 7 people with DR and 14 individuals without DR. Subsequently, we conducted biochemical indices analyses and qRT-PCR.We randomly divided RGCs into low glucose groups, HG groups, HG + inhibitor negative control groups, and HG\u00a0+\u00a0miR-29a-5p inhibitor groups. SIRT3 siRNA was transfected into RGCs through lipofectamine 3000 reagent.Cell vitality was detected by MTT; qRT-PCR was applied to identify miR-29a-5p expression; Detectionof ROS, SOD, and MDAlevels was quantified using the DCFH-DA, WST-1, and colorimetric methods, respectively; IL-6 and TNF-\u03b1contents were analyzed utilizing ELISA; Dual-luciferase gene reporter experiment was used to examine if SIRT3 is the specific target gene of miR-29a-5p; Flow cytometryevaluatedapoptosisin RGCs; The technique of Western blotting identified the presence of caspase-3 proteins. The expression of miR-29a-5p was markedly elevated in individuals with DR, and it had positive correlations with levels of Total Cholesterol (TC) and Fasting Blood Glucose (FBG).High glucose significantly induced RGC apoptosis and upregulated the miR-29a-5p gene. Transfection of miR-29a-5p inhibitor protected RGCs against HG-induced oxidative injury, inflammation, and apoptosis. Furthermore, the dual-luciferase reporter experiment provided confirmation that SIRT3 was a target gene of miR-29a-5p, as it negatively regulated SIRT3 expression. Notably, SIRT3 knockdown abolished the protection of miR-29a-5p inhibition on RGCs. Suppression of the miR-29a-5p gene safeguards RGCs against harm caused by HG via boosting SIRT3 signaling, which might provide a new prevention and treatment strategy for DR.\n\nID: 40414590\nTitle: Macular Microvasculature Asymmetry Analysis for Evaluating Open-Angle Glaucoma in Diabetic Retinopathy Patients Treated With Pan-Retinal Photocoagulation.\nAbstract: To evaluate the usefulness of vertical asymmetry analysis of macular microvasculature for diagnosis of open-angle glaucoma (OAG) in diabetic retinopathy (DR) patients who have undergone pan-retinal photocoagulation (PRP). Retrospective, cross-sectional diagnostic evaluation. DR patients with PRP were categorized into those without OAG (Group 1) and those with OAG (Group 2). Peripapillary retinal nerve fiber layer (pRNFL) thickness and macular vessel density (VD) were measured, and the vertical difference in pRNFL (vdRNFL) and VD (vdVD) was determined as the absolute difference between the superior and inferior sectors. Diagnostic performance was analyzed by calculating the area under the curve (AUC). Analyses included 128 eyes (Group 1: 68 and Group 2: 60). The mean pRNFL thickness was 93.9 \u00b1 14.8 \u00b5m in Group 1 and 85.5 \u00b1 14.4 \u00b5m in Group 2 (P = .009). The mean vdRNFL was 13.1 \u00b1 10.9 \u00b5m in Group 1 and 14.4 \u00b1 12.6 \u00b5m in Group 2 (P = .607). The mean VD was 15.9 \u00b1 3.3 mm-1 in Group 1 and 15.3 \u00b1 2.6 mm-1 in Group 2 (P = .380), whereas the vdVD was 0.6 \u00b1 0.6 mm-1 in Group 1 and 1.6 \u00b1 1.4 mm-1 in Group 2 (P < .001). The AUC for diagnostic accuracy was 0.812 for vdVD, significantly higher than that for other factors (all P < .001). Relying on pRNFL thickness for OAG evaluation in PRP-treated patients is not recommended. Analysis of vertical microvasculature asymmetry can serve as a useful factor for diagnosing OAG.\n\nID: 40384765\nTitle: Serum pro-brain natriuretic peptide correlates with optical coherence tomography indices in diabetic retinopathy.\nAbstract: Serum pro-brain natriuretic peptide (BNP) is a 108-amino-acid prohormone that inhibits vascular endothelial growth factor (VEGF) secretion, protecting pericytes from cell death and decreasing retinal vascularization. The purpose of this study was to investigate the correlation of serum pro-BNP with optical coherence tomography (OCT) indices in diabetic retinopathy. This cross-sectional study investigated 96 consecutive subjects aged between 40 and 65 years: controls n = 24, no diabetic retinopathy (NoDR) n = 24, non-proliferative diabetic retinopathy (NPDR) n = 24, and proliferative diabetic retinopathy (PDR) n = 24. Same-day analysis of blood samples for serum pro-BNP levels was performed and spectral-domain OCT (SD-OCT) was used to measure the following OCT indices: OCT angiography (OCTA) superficial vessel density (SVD), deep vessel density (DVD), and foveal avascular zone (FAZ); OCT retinal nerve fiber layer (RNFL); and OCT ganglion cell analysis (GCA). The mean serum pro-BNP levels for the control, NoDR, NPDR, and PDR groups were 14.07 \u00b1 11.51, 27.35 \u00b1 11.81, 280.44 \u00b1 106.13, and 122.33 \u00b1 43.66 pg/ml, respectively. The mean values of the various OCT parameters correlated with serum pro-BNP were OCTA SVD (r = - 0.360), OCTA DVD (r = 0.408), OCTA FAZ (r = 0.475), OCT RNFL (r = - 0.215) and OCT GCA (r = - 0.285; p<0.001). The serum pro-BNP levels were higher in the NPDR group than in the NoDR group and much lower in the PDR group than in the NPDR group, reflecting a lowering of the protective barrier. These results correlated with the changes in various OCT indices.\n\nID: 40266592\nTitle: Structure-Function Associations Between Quantitative Contrast Sensitivity Function And Peripapillary Optical Coherence Tomography Angiography in Diabetic Retinopathy.\nAbstract: To assess changes in radial peripapillary capillary (RPC) microvasculature and their impact on visual function, measured by visual acuity (VA) and contrast sensitivity, in diabetic retinopathy (DR). This was a cross-sectional study in 96 eyes of 67 patients, including controls, diabetes without DR (DMnoDR), nonproliferative DR (NPDR), and proliferative DR (PDR) groups. Participants underwent same-day quantitative contrast sensitivity function (qCSF) and 6 \u00d7 6 mm OCT angiography (OCTA) centered on the optic disc. The Peripapillary Nerve Fiber Layer Microvasculature Density algorithm (ARI Network) was used to calculate capillary perfusion density (total area of perfused microvasculature per unit area), capillary flux index (CFI, total weighted area of perfused microvasculature per unit area), and retinal nerve fiber layer (RNFL) thickness surrounding the optic disc. Mixed-effects multivariable regression models, controlling for age, hypertension, and lens status, evaluated associations between RPC OCTA metrics, DR severity, VA, and qCSF. Significant RPC microvascular changes were observed across DR stages. Capillary perfusion density decreased with DR severity and even before retinopathy onset in DMnoDR versus controls (\u03b2avg = -0.42, P\u00a0=\u00a00.021). PDR compared to NPDR showed a significant decrease in CFI (\u03b2 = -1.02 to -0.92, P < 0.01) and in RNFL (\u03b2avg = -0.71, P\u00a0=\u00a00.033). CFI had significant associations with qCSF at various spatial frequencies (\u03b2\u00a0=\u00a00.20 to 0.34, P\u00a0=\u00a00.002 to 0.042), but not with VA. Radial peripapillary capillary perfusion density worsens with onset of diabetes and increasing severity of DR while capillary flux index is more significantly affected later in disease. Structure-function associations suggest that DR-induced peripapillary microvascular changes are more strongly associated with contrast sensitivity changes than with visual acuity.\n\nID: 40216954\nTitle: CaMK2A/CREB pathway activation is associated with enhanced mitophagy and neuronal apoptosis in diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR) is a common complication of diabetes mellitus, characterized by progressive neurodegeneration and vision impairment. The Ca2+/calmodulin-dependent protein kinase II alpha (CaMK2A) and cAMP response element-binding protein (CREB) signaling pathway has been implicated in various neurological disorders. However, its role in DR pathogenesis remains elusive. We established a DR mouse model by streptozotocin administration and performed histological, biochemical, and molecular analyses to investigate the involvement of CaMK2A/CREB signaling and its interplay with mitophagy. Additionally, we employed in vitro high-glucose (HG) treatment in primary mouse retinal ganglion cells to dissect the underlying mechanisms. Pharmacological and genetic modulations were utilized to target CaMK2A/CREB pathway and mitophagy. In the DR model, we observed retinal degeneration, increased apoptosis, and reduced neurotransmitter production, accompanied by enhanced mitophagy and activation of the CaMK2A/CREB pathway. HG induction in retinal ganglion cells recapitulated these findings, and autophagy inhibition partially rescued cell death but failed to suppress CaMK2A/CREB activation, suggesting mitophagy as a downstream consequence. CaMK2A knockdown or CREB phosphorylation inhibition attenuated HG-induced mitophagy, apoptosis, and neurotransmitter depletion, while CREB activation exacerbated these effects. CaMK2A silencing mitigated DR progression, oxidative stress, inflammation, and neuronal loss, akin to dopamine/carbidopa administration in DR mouse model. Our findings reveal the involvement of CaMK2A/CREB signaling activation and enhanced mitophagy in DR, suggesting these pathways may be therapeutically relevant targets for DR management.\n\nID: 40215758\nTitle: Pattern ERG, pattern VEP, and GCL thickness in diabetic patients with no diabetic retinopathy.\nAbstract: The main objective of this study was to compare the retinal ganglion cell (RGC) function of diabetic patients without diabetic retinopathy with the RGC function of a control group, using functional tests and anatomical assessments. A cross-sectional prospective pilot study was conducted on two groups. We compared the results of functional tests (Pattern ERG and Pattern VEP - PERG and PVEP) and anatomical tests (macular and RNFL OCT) in a diabetic group without diabetic retinopathy to a control group. The \u03c72 test was used to study qualitative data, and the t test was used for quantitative data. The significance threshold was a P value less than 0.05. A total of 37 eyes were included in the study. None of the demographic variables showed any significant association or effect on any of the two groups. GCL thickness was significantly reduced in the diabetic group in the superior, inferior, and nasal outer circles, with a P value <0.001. The amplitude of the P100 wave was significantly reduced in the diabetic group, with a P value<0.05 for the pattern sizes of 60' and 30', and the diabetic group had a longer latency for the 15' VEPs. All of the components of the PERG responses were significantly altered in the diabetic group, with a P value<0.05. Our study indicates that combining different tests may be used as an early means of detection of compromised retinal neuron function in diabetic eyes during the course of early diabetic retinopathy.\n\nID: 40211015\nTitle: Quantitative automated pupillometry in diabetic patients and correlation with retinal nerve fibre layer thickness.\nAbstract: To evaluate pupillary function in diabetic patients by automated pupillometry, and to study the correlation between retinal nerve fibre layer (RNFL) thickness and pupillary parameters. Diabetic patients underwent detailed systemic and ophthalmic examination including automated pupillometry. The pupillometer used a white stimulus and was equipped with a high-resolution infrared (880\u2009nm) camera. Static pupillary diameters were captured at different levels of background intensity-photopic high (100\u2009cd/m2), photopic low (10\u2009cd/m2), mesopic high (1\u2009cd/m2), and mesopic low (0.1\u2009cd/m2). Dynamic pupillary responses were elicited with white-light flashes (total luminance 100\u2009cd/m2, stimulus on time 200\u2009ms, off time 3300\u2009ms). RNFL thickness was measured using spectral domain optical coherence tomography (OCT) RESULTS: The study had 38 diabetic patients with retinopathy (DWR), 27 diabetic patients without retinopathy (DWOR), and 25 healthy controls. Static pupillometry showed significant differences between the three groups. Diabetic patients, both with and without retinopathy had significantly smaller pupillary diameters compared to controls, (p\u2009<\u20090.001). The amplitude of contraction and velocity of contraction was significantly lower in diabetic patients compared to controls (p\u2009<\u20090.001), and between DWR compared to DWOR (p\u2009<\u20090.001). Percent pupillary contraction differed between DWR and controls (p\u2009=\u20090.001) There was a significant difference in superior RNFL thickness between DWR and DWOR (p\u2009=\u20090.032). The superior quadrant RNFL correlated with the maximum number of pupillometry parameters. The amplitude and velocity of contraction are affected early in diabetic autonomic dysfunction. There is a relationship between RNFL thickness and pupillometry parameters in diabetic patients, indicating simultaneous neurodegeneration and autonomic neuropathy.\n\nID: 40180022\nTitle: Nitric oxide mediates negative feedback on the TXNIP/NLRP3 inflammasome pathway to prevent retinal neurovascular unit dysfunction in early diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision impairment in working-age adults, and is driven by complex neurovascular dysfunction. This study aimed to elucidate whether nitric oxide (NO) can modulate the TXNIP/NLRP3 inflammasome pathway and mitigate retinal neurovascular unit (NVU) damage during early DR. In an in vitro co-culture system, silencing TXNIP or NLRP3 in retinal microglia (RMG) significantly upregulated glial cell-derived neurotrophic factor (GDNF) and downregulated inducible nitric oxide synthase (iNOS) expression in retinal ganglion cells (RGC). Moreover, it resulted in decreased iNOS and vascular endothelial growth factor A (VEGFA) levels and enhanced the expression of tight junction proteins (Occludin and ZO-1) in retinal microvascular endothelial cells (RMEC), while also reducing NO release and inhibiting RMEC tube formation. Treatment with S-nitroso-N-acetyl penicillamine (SNAP), an NO donor, significantly downregulated TXNIP/NLRP3 inflammasome signaling in RMG, decreased RGC apoptosis, and inhibited tube formation in RMEC. It also upregulated GDNF, suppressed iNOS in RGC, decreased VEGFA, and improved tight junction proteins in RMEC. Treatment with 1400W, an iNOS inhibitor, resulted in decreased NO concentration and increased IL-1\u03b2 levels in the co-culture supernatant, without significantly affecting iNOS expression in RGC or RMEC. In an early DR rat model, Electroretinogram (ERG), Optical Coherence Tomography (OCT), Fluorescein Angiography (FFA), Evans blue assays, Immunofluorescence staining, and TUNEL staining confirmed that sodium nitroprusside (SNP), NO donor administration mitigated retinal neural and vascular dysfunction, and preserved retinal NVU integrity. Concurrently, SNP treatment reduced IL-1\u03b2 expression and increased GDNF and Occludin levels in the early DR retina. Genetic Association Database (GAD) enrichment analysis and protein-protein interaction (PPI) network validation indicated that NO functions as a downstream mediator of the TXNIP/NLRP3 inflammasome pathway and exhibits a strong association with DR. These findings suggest that NO mediates negative feedback in the TXNIP/NLRP3 inflammasome pathway to exert protective effects against retinal NVU dysfunction in early DR, thereby offering potential therapeutic strategies for early intervention in DR.\n\nID: 40158743\nTitle: STING immune activation of microglia aggravating neurovascular unit damage in diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR) is the leading cause of blindness and is pathologically characterized by neuroinflammation and neovascularization. Retinal homeostasis is critically maintained by the retinal neurovascular unit (NVU), which can be disrupted by abnormal activation of microglia in DR. However, the underlying mechanism remains unclear. Here, we provide the first evidence of upregulated stimulator of interferon genes (STING) in microglia within fibrovascular membranes (FVMs) and retinas from oxygen-induced retinopathy (OIR) and streptozotocin (STZ)-induced diabetic mice. Furthermore, we identified STING upregulation in BV2 cells stimulated with high glucose (HG) or hypoxia, accompanied by mitochondrial dysfunction and cytoplasmic leakage of damaged mitochondrial DNA (mtDNA). Pharmacologic or genetic inhibition of STING in microglia prevented their activation and polarization. Next, we demonstrated that STING-deficient BV2 cells reversed the proangiogenic behavior of endothelial cells and protected retinal ganglion cells (RGCs) from oxidative stress. Finally, intravitreal injection of AAV-STING alleviated retinal neurovascular pathologies in both OIR and STZ mice. This study demonstrated that the release of mtDNA mediates STING immune activation of microglia, which further exacerbates NVU damage in DR. In contrast, immunosuppressing STING in microglia could serve as a potential therapeutic strategy.\n\nID: 40157727\nTitle: Changes in peripapillary microvasculature and retinal nerve fibre layer in diabetes and diabetic retinopathy using optical coherence tomographic angiography: a community-based, cross-sectional study.\nAbstract: To evaluate changes in the peripapillary retinal microvasculature and retinal nerve fibre layer (RNFL) in diabetic participants with various stages of diabetic retinopathy (DR) using swept-source optical coherence tomographic angiography (OCTA). Community-based, cross-sectional study. This study was conducted in a tertiary teaching hospital in Guangzhou, China. A total of 1325 ocular-treatment-naive participants, of whom 1115 had no DR and 210 had DR, were recruited in a community in Guangzhou, China. A commercially available OCTA device was used to obtain various peripapillary retinal microvascular metrics centred on the optic disc, including vessel density (VD), vessel length density (VLD) and vessel diameter index (VDI). The peripapillary RNFL thickness was automatically obtained using built-in software. Linear regression analyses were used to evaluate the association of the peripapillary OCTA parameters (VD, VLD and VDI), RNFL thickness with various DR stages and average RNFL thickness with peripapillary OCTA parameters. Moderate and severe DR had progressively decreased VD in the peripapillary ring (\u03b2 = -0.72, 95% CI = -1.31\u2009to -0.14 and -1.79, 95% CI = -2.81\u2009to -0.77, respectively) and other regions (all p<0.05). Similar changes were observed between peripapillary VLD and moderate and severe DR (all p<0.05). Moderate (\u03b2 = -4.56, 95% CI = -8.97\u2009to -0.15, p=0.043) and severe DR (\u03b2 = -10.12, 95% CI = -18.29\u2009to -1.95, p=0.015) had significant thinner peripapillary RNFL in the inferior quadrant. VD and VLD were linearly associated with the average RNFL in the peripapillary ring and average peripapillary area (all p<0.05). The peripapillary retinal microvasculature and RNFL were significantly reduced with the progression of DR, which suggests that monitoring differences in peripapillary microvasculature and the RNFL may be a promising approach to detecting DR progression.\n\nID: 40131295\nTitle: Neuronal Degeneration and Glial Activation in the Absence of Vascular Changes in Human Retinas of Patients With Diabetes.\nAbstract: This study assessed retinal cells in the macula of human donors with diabetes with or without retinopathy. Seventeen human donor retinas were classified as diabetes mellitus (DM, n = 7), diabetes with diabetic retinopathy (DR, n = 3), or control (n = 8). Macular transversal sections were analyzed for photoreceptors, bipolar cells, horizontal cells, ganglion cells, their synaptic connections, and M\u00fcller cells using immunohistochemistry and confocal microscopy. The densities of bipolar cells, horizontal cells, and ganglion cells and the thickness of the inner plexiform layer (IPL) were quantified around the fovea. In the macula, cone photoreceptors elongated their axons to establish synapses with bipolar and horizontal cells in intraretinal cysts. Bipolar cells were reduced in the DM group compared to the control (P < 0.001), and rod bipolar cells showed morphological alterations in the cell body and synaptic terminals in both diabetic groups. Morphological changes were observed in both plexiform layers, with a decrease in the IPL thickness in DR. Horizontal cell terminals sprouted into the outer and inner retina in DR, despite no density differences existing between DM and control (P = 0.498). Ganglion cell density was reduced in the DM retinas compared to control (P < 0.001). M\u00fcller cells exhibited thickening of their cell bodies and end feet in all diabetic retinas. The degeneration of neurons and synaptic connectivity within the macula in individuals with DM, even in the absence of clinical vascular signs, is associated with impaired visual function. These early changes suggest potential new biomarkers for imaging techniques and emphasize the need for therapies for diabetic patients without clinical signs.\n\nID: 40118255\nTitle: Methyltransferase-like enzyme 14 exacerbates retinal ganglion cell damage and diabetic retinopathy through N6-methyladenosine-dependent upregulation of pleckstrin homology domain and leucine rich repeat protein phosphatase 2.\nAbstract: N6-methyladenosine (m6A) modification of pleckstrin homology domain and leucine rich repeat protein phosphatase 2 (PHLPP2), mediated by methyltransferase-like enzyme 14 (METTL14), plays a critical role in regulating PHLPP2 expression across various pathological conditions. This study aims to ascertain whether METTL14 influences m6A methylation of PHLPP2 in diabetic retinopathy (DR) and to delineate the precise function of the METTL14/PHLPP2 axis in disease progression. METTL14 levels were observed to be elevated in retinas of DR rats and in HG-stimulated RGCs, coinciding with an increase in PHLPP2 m6A modification. Knockdown of METTL14 resulted in significant reductions in PHLPP2 expression and its m6A modification. Silencing METTL14 mitigated HG-induced damage in RGCs, which was linked to the inhibition of apoptosis, oxidative stress and inflammation. This protective effect could be negated through the restoration of PHLPP2. METTL14 knockdown modulated the AKT/GSK-3\u03b2/Nrf2 signal cascade through PHLPP2. Silencing METTL14 resulted in the downregulation of METTL14 and PHLPP2 in the retinas of DR rats, ameliorated visual function impairment and reduced the pathological alterations. These protective effects of METTL14 silencing against DR were also weakened when PHLPP2 was restored. Overall, these results suggest that suppressing METTL14 improves HG-induced damage in RGCs and protects against DR by downregulating PHLPP2 through m6A modification.\n\nID: 40096829\nTitle: Correlation between Systemic Inflammation and Morphological Changes of Retinal Neurovascular Unit in Patients with Early Signs of Diabetic Retinopathy: An OCT and OCT-Angiography Study.\nAbstract: The aim of the study was to investigate the correlation between systemic inflammation biomarkers and morphological changes of retinal neurovascular unit (RNVU) under optical coherence tomography (OCT) and OCT angiography (OCTA) in type 2 diabetic patients with early signs of diabetic retinopathy (DR). This cross-sectional study was carried out among 93 type 2 diabetic patients with early signs of DR (170 eyes), ranging from level 10 to level 35 based on ETDRS DR severity scale score. Age-, sex-, and axial length-matched normal subjects were enrolled as controls. Systemic inflammation biomarkers including neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and systemic immune-inflammatory index (SII) were calculated based on peripheral blood results. Retinal neuronal changes of RNVU were identified by accessing the thickness of macular retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) using OCT. Retinal microvascular alterations of RNVU were evaluated by measuring macular vessel density (VD) and size of foveal avascular zone (FAZ) using OCTA. GCL thickness was significantly correlated with NLR (r = -0.183, p = 0.017) and MLR (r = -0.235, p = 0.002), RNFL thickness was significantly associated with MLR (r = -0.210, p = 0.008), FAZp was positively correlated with NLR (r = 0.153, p = 0.046) and MLR (r = 0.187, p = 0.014), FAZa was positively correlated with MLR (r = 0.189, p = 0.014), and VD was significantly correlated with NLR (r = -0.188, p = 0.014) on spearman correlation analysis. Additionally, VD was independently associated with SII in both univariable and multivariable GLM analysis (p < 0.05). This difference still remained statistically significant during subgroup analysis after controlling DM duration. Systemic inflammation biomarkers including NLR, MLR, and SII are significantly associated with not only retinal microvascular alterations but also retinal neuronal changes, providing evidence that systemic inflammation may play a crucial role on the early morphological changes of RNVU and early DR pathogenesis. SII is independently associated with VD, which supports SII may serve as a potential biomarker for monitoring early microvascular changes of DR.\n\nID: 40084285\nTitle: Serum pro-brain natriuretic peptide correlates with optical coherence tomography indices in diabetic retinopathy.\nAbstract: Serum pro-brain natriuretic peptide (BNP) is a 108-amino-acid prohormone that inhibits vascular endothelial growth factor (VEGF) secretion, protecting pericytes from cell death and decreasing retinal vascularization. The purpose of this study was to investigate the correlation of serum pro-BNP with optical coherence tomography (OCT) indices in diabetic retinopathy. This cross-sectional study investigated 96 consecutive subjects aged between 40 and 65 years: controls n = 24, no diabetic retinopathy (NoDR) n = 24, non-proliferative diabetic retinopathy (NPDR) n = 24, and proliferative diabetic retinopathy (PDR) n = 24. Same-day analysis of blood samples for serum pro-BNP levels was performed and spectral-domain OCT (SD-OCT) was used to measure the following OCT indices: OCT angiography (OCTA) superficial vessel density (SVD), deep vessel density (DVD), and foveal avascular zone (FAZ); OCT retinal nerve fiber layer (RNFL); and OCT ganglion cell analysis (GCA). The mean serum pro-BNP levels for the control, NoDR, NPDR, and PDR groups were 14.07 \u00b1 11.51, 27.35 \u00b1 11.81, 280.44 \u00b1 106.13, and 122.33 \u00b1 43.66 pg/ml, respectively. The mean values of the various OCT parameters correlated with serum pro-BNP were OCTA SVD (r = - 0.360), OCTA DVD (r = 0.408), OCTA FAZ (r = 0.475), OCT RNFL (r = - 0.215) and OCT GCA (r = - 0.285; p<0.001). The serum pro-BNP levels were higher in the NPDR group than in the NoDR group and much lower in the PDR group than in the NPDR group, reflecting a lowering of the protective barrier. These results correlated with the changes in various OCT indices.\n\nID: 39995100\nTitle: Damage and repair in retinal degenerative diseases: Molecular basis through clinical translation.\nAbstract: Retinal ganglion cells are the bridging neurons between the eye and the central nervous system, transmitting visual signals to the brain. The injury and loss of retinal ganglion cells are the primary pathological changes in several retinal degenerative diseases, including glaucoma, ischemic optic neuropathy, diabetic neuropathy, and optic neuritis. In mammals, injured retinal ganglion cells lack regenerative capacity and undergo apoptotic cell death within a few days of injury. Additionally, these cells exhibit limited regenerative ability, ultimately contributing to vision impairment and potentially leading to blindness. Currently, the only effective clinical treatment for glaucoma is to prevent vision loss by lowering intraocular pressure through medications or surgery; however, this approach cannot halt the effect of retinal ganglion cell loss on visual function. This review comprehensively investigates the mechanisms underlying retinal ganglion cell degeneration in retinal degenerative diseases and further explores the current status and potential of cell replacement therapy for regenerating retinal ganglion cells. As our understanding of the complex processes involved in retinal ganglion cell degeneration deepens, we can explore new treatment strategies, such as cell transplantation, which may offer more effective ways to mitigate the effect of retinal degenerative diseases on vision.\n\nID: 42459363\nTitle: Inhibiting the uPAR/FPR1 interactions reduces blood-retinal barrier breakdown and improves retinal function in a rat model of diabetes.\nAbstract: Diabetic retinopathy (DR) is a leading cause of blindness characterized by early neurovascular damage driven by hyperglycemia-induced mechanisms, including inflammation. The system composed of the urokinase-type plasminogen activator (uPA) and its receptor (uPAR) has previously emerged as a potential regulator of the pro-inflammatory events in DR, possibly through the interaction of uPAR with its lateral partners, such as formyl peptide receptors (FPRs). This study explored whether the inhibition of uPAR/FPR1 crosstalk may reduce early neurovascular alterations in DR by targeting inflammation. To this aim, the new FPR1 antagonist N-19004 was tested in a rat model of streptozotocin-induced diabetes. N-19004 was administered subcutaneously for 7\u202fdays at 1\u202fmonth from diabetes onset. Immunofluorescence, RT-qPCR, Western blot and Evans blue perfusion were performed to evaluate the effects of N-19004 on inflammation, reactive gliosis, blood-retinal barrier (BRB) integrity and apoptosis. In addition, electroretinogram (ERG) was used to assess N-19004 efficacy on retinal function. N-19004 inhibited the activation of inflammation-related transcription factors, including nuclear factor kappa-light-chain-enhancer of activated B cells and signal transducer and activator of transcription 3, leading to reduced interleukin-1\u03b2 and tumor necrosis factor-\u03b1 expression. The attenuation of inflammatory processes resulted in reduced glial activation, as indicated by lower glial fibrillary acidic protein expression and M\u00fcller cell gliosis. The anti-inflammatory activity of N-19004 was accompanied by decreased BRB breakdown, as demonstrated by N-19004-mediated reduction of vascular endothelial growth factor, increased levels of tight junction components and diminished vessel leakage. The amelioration of BRB integrity was associated with reduced activation of caspase 3 and partial preservation of scotopic ERG a- and b-wave amplitudes, thereby improving retinal viability and function in N-19004-treated STZ rats. These results support the possible involvement of uPAR/FPR1 interactions in the regulation of DR-related inflammation and suggest a novel therapeutic target for the management of the early phases of disease.\n\nID: 42352347\nTitle: L-Serine Attenuates Metabolic and Behavioural Features of Diabetic Neuropathy with Dose-Dependent Central Proteomic Correlates in a Rat Model.\nAbstract: Diabetic neuropathy (DN) is a multifactorial complication of diabetes mellitus driven by chronic hyperglycemia, insulin resistance, and disturbed metabolic homeostasis, leading to progressive injury of both the peripheral and central nervous systems. This study investigated whether L-serine supplementation could attenuate DN through dose-dependent metabolic and neuroprotective mechanisms in a high-fat diet (HFD) plus streptozotocin (STZ)-induced diabetic rat model. Male Wistar rats (n = 8 per group) were allocated to five groups: normal control (NC), diabetic control (DC), pioglitazone (PIO; 1.5 mg/kg/day), low-dose L-serine (S1; 200 mg/kg/day), and high-dose L-serine (S2; 400 mg/kg/day). After 60 days of oral gavage, behavioural testing, glucose and insulin profiling, HOMA-IR calculation, brain histopathology, nerve growth factor (NGF) immunohistochemistry, and LC-MS/MS-based proteomic analysis of cerebral tissue were performed. Diabetic rats exhibited marked hyperglycaemia (355.33 \u00b1 4.72 mg/dL), hyperinsulinaemia, severe insulin resistance (HOMA-IR 16.8 \u00b1 3.2; a 14-fold increase), impaired thermal nociception, motor dysfunction, and pronounced neuronal degeneration. L-serine supplementation significantly improved metabolic status: S1 reduced HOMA-IR by 77.4% and S2 by 87.5% relative to diabetic controls (p < 0.001). High-dose L-serine produced greater improvements in thermal sensitivity, motor coordination (rotarod latency 26.67 \u00b1 1.52 s vs. 16.1 \u00b1 0.85 s in DC; p < 0.05), and NGF expression (8.6-fold increase vs. DC). Histopathology confirmed attenuation of neuronal injury and gliosis in both treatment groups. Exploratory, group-level proteomic profiling identified dose-specific molecular signatures: S1 was predominantly associated with carbohydrate, lipid, and biosynthetic pathways, whereas S2 was associated with synaptic, neurotransmission-related, and proteostasis pathways. Within the constraints of an exploratory design-group-level pooled proteomics, analysis of cerebral rather than peripheral-nerve tissue, and only two doses-these findings indicate that L-serine attenuates the metabolic and behavioural features of experimental diabetic neuropathy and generates the testable hypothesis of dose-dependent neuro-metabolic remodelling. The proteomic signatures are hypothesis-generating and require orthogonal validation before any mechanistic or translational inference can be drawn.\n\nID: 41751986\nTitle: Exercise-Induced Irisin: A Novel Strategy for Neuroinflammation Alleviation and Neurorepair in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) stands as a classic microvascular complication of diabetes mellitus. DR is characterized by multidimensional pathological changes in retinal neurons, microvasculature and supportive cells, leading to an intricate damage network. It is predominantly marked by neuropathy, encompassing retinal neuronal dysfunction, aberrant activation of glial cells, and degeneration of synaptic structures. In severe instances, it can result in visual impairment and, in the worst-case scenario, blindness. As diabetes progresses, retinal nerve tissue frequently sustains damage owing to oxidative stress, inflammatory responses, and compromised mitochondrial function. Although the precise neuroprotective mechanisms remain elusive, exercise has the ability to bolster mitochondrial function in retinal cells, diminish oxidative stress, and curb inflammatory reactions, thereby safeguarding the neurophysiological function of the retina. Irisin is a myokine primarily secreted by skeletal muscles in response to exercise stimulation. Moreover, being produced in trace amounts across a variety of tissues, it has the capacity to regulate the physiological processes of multiple organs. Recent studies have indicated that irisin can exert powerful neuroprotective effects by enhancing cellular glucose uptake, improving mitochondrial function, inhibiting the expression of pro-inflammatory factors, and resisting ferroptosis. In this review, we systematically collated and synthesized existing evidence on irisin-related signaling pathways and comprehensively assessed its regulatory potential in alleviating neuroinflammation and promoting neural repair in diabetic retinopathy and offer insights into future research directions in this field.\n\nID: 41518430\nTitle: Exploring retinal microglia: development, degeneration, and iPSC-derived model systems.\nAbstract: Microglia are key regulators of retinal development, immune surveillance, and neuroprotection. Derived from yolk sac progenitors, they exhibit precise laminar distribution within the retina and fulfill diverse physiological roles, including synaptic pruning, phagocytosis, and modulation of inflammation and angiogenesis. In retinal diseases such as retinitis pigmentosa, age-related macular degeneration, and diabetic retinopathy, microglial activation contributes to neurodegeneration and pathological remodeling. This review summarizes recent advances in our understanding of retinal microglial ontogeny, distribution, and function, with particular emphasis on human pluripotent stem cell (hPSC)-derived microglia (iMG) .We highlight in vitro and chimeric iMG-based models that facilitate human-specific studies and discuss their emerging applications in retinal disease modeling, therapeutic screening, and personalized medicine.\n\nID: 41507600\nTitle: Does Neuroglobin Protect Against Stroke? Insights Into the Role of Neurovascular Unit Cells.\nAbstract: Ischemic stroke, a leading cause of disability and mortality, initiates a complex damage cascade within the neurovascular unit (NVU), leading to blood-brain barrier (BBB) disruption and neuroinflammation that severely exacerbates secondary injury. Neuroglobin (Ngb), an endogenous protein induced by brain injury, represents a high-potential neuroprotective target. While the precise mechanisms underlying its protective action remain incompletely elucidated, substantial evidence points to its multifaceted ability to mitigate ischemic damage. To fully unlock this potential, a fundamental understanding of how neurons, astrocytes, microglia, and pericytes, coordinate their function in response to stress, and specifically identifying the role Ngb plays within this integrated cellular network, is required. This review examines the post-stroke interplay among these cells, analyzing current knowledge about how Ngb modulates the collective inflammatory response by suppressing pro-inflammatory pathways and fostering a neuroprotective environment. Furthermore, Ngb's upregulation in glial cells and pericytes promotes direct neuronal repair mechanisms, such as neurite outgrowth and axonal regeneration, while supporting neuronal survival and BBB integrity. Importantly, evidence suggests that Ngb's efficacy is most pronounced when its intracellular concentration exceeds the levels achieved through physiological upregulation. In this regard, we integrate broad preclinical evidence with specific insights from nanoparticle-mediated delivery systems that enable effective Ngb transport to NVU cells. These synthesized findings demonstrate beneficial outcomes in stroke models, driven by the modulation of mitochondrial dynamics, cytoskeletal remodeling, and synaptic regeneration pathways. Collectively, the literature indicates that targeted therapeutic Ngb may enhancement strategies effectively complement endogenous levels to orchestrate protective responses across the NVU. Nonetheless, a detailed investigation into the therapeutic utility of Ngb is still required to fully translate encouraging preclinical findings into successful clinical application for improving stroke outcomes.\n\nID: 40368327\nTitle: Neurotrophins of the retina and their involvement in early-stage diabetic retinopathy in an animal model of type 1 diabetes mellitus.\nAbstract: IntroductionDiabetic retinopathy (DR) is a blindness-causing disease which belongs to the group of neurodegenerative diseases. Neurodegeneration of the retina is a process, in which retinal neurons suffer irreversible damage. This study aimed to assess the involvement of neurotrophins (brain-derived neurotrophic factor [BDNF] and nerve growth factor [NGF]) in the pathogenesis of DR.MethodsThe study was performed using male Lewis rats with type 1 diabetes mellitus induced by streptozotocin, and the control group included rats without drug administration. In vivo examinations performed over four weeks included eye fundus imaging, measurement of intraocular pressure, and glycemia. After sacrifice, serum and eyeballs were harvested. Post-mortem analyses included a histopathological analysis of the retina and the measurement of BDNF and NGF levels in the serum and eyeball homogenate.ResultsIn the experimental group, early-stage DR was confirmed, and changes in the retina were observed: diabetic rats had relatively thicker outer nuclear layers and relatively thinner inner plexiform layers. A lower level of BDNF was observed in the serum of rats with DR, while the level of NGF in the eyeball homogenate positively correlated with vascular changes.ConclusionsThe observed changes in the levels of neurotrophins in early-stage DR may indicate their involvement in the disease pathogenesis.\n\nID: 39238380\nTitle: Neurotrophins in Peripheral Neuropathy: Exploring Pathophysiological Mechanisms and Emerging Therapeutic Opportunities.\nAbstract: Neuropathies, which encompass a wide array of peripheral nervous system disorders, present significant challenges due to their varied causes, such as metabolic diseases, toxic exposures, and genetic mutations. This review article, focused on the critical role of neurotrophins in peripheral neuropathy, highlights the intricate balance of neurotrophins necessary for nerve health and the pathophysiological consequences when this balance is disturbed. Neurotrophins, including Nerve Growth Factor (NGF), Brain-Derived Neurotrophic Factor (BDNF), Neurotrophin-3 (NT- 3), and Neurotrophin-4 (NT-4), are essential for neuronal survival, axonal growth, and synaptic plasticity. Their signaling pathways are crucial for maintaining peripheral nervous system integrity, primarily via the Tropomyosin receptor kinase (Trk) receptors and the p75 neurotrophin receptor p75(NTR). Dysregulation of neurotrophins is implicated in various neuropathies, such as diabetic neuropathy and chemotherapy-induced peripheral neuropathy, leading to impaired nerve function and regeneration. Understanding neurotrophin signaling intricacies and their alterations in neuropathic conditions is crucial for identifying novel therapeutic targets. Recent advancements illuminate neurotrophins' potential as therapeutic agents, promising disease-modifying treatments by promoting neuronal survival, enhancing axonal regeneration, and improving functional recovery post-nerve injury. However, translating these molecular insights into effective clinical applications faces challenges, including delivery methods, target specificity, and the instability of protein- based therapies.\n\nID: 39084273\nTitle: Underlying mechanisms of traditional Chinese medicine in the prevention and treatment of diabetic retinopathy: Evidences from molecular and clinical studies.\nAbstract: As one of the most serious microvascular complications of diabetes mellitus (DM), diabetic retinopathy (DR) can cause visual impairment and even blindness. With the rapid increase in the prevalence of DM, the incidence of DR is also rising year by year. Preventing and effectively treating DR has become a major focus in the medical field. Traditional Chinese medicine (TCM) has a wealth of experience in treating DR and has achieved significant results with various herbs and TCM prescriptions. Traditional Chinese Medicine (TCM) provides a comprehensive therapeutic strategy for diabetic retinopathy (DR), encompassing anti-inflammatory and antioxidant actions, anti-neovascularization, neuroprotection, regulation of glucose metabolism, and inhibition of apoptosis. This review provides an overview of the current status of TCM treatment for DR in recent years, including experimental studies and clinical researches, to explore the clinical efficacy and the underlying modern mechanisms of herbs and TCM prescriptions. Besides, we also discussed the challenges TCM faces in treating DR, such as drug-drug interactions among TCM components and the lack of high-quality evidence-based medicine practice, which pose significant obstacles to TCM's application in DR.\n\nID: 38936912\nTitle: Exploring Neuroprotective Effects of Topical Brimonidine in Experimental Diabetic Retinopathy.\nAbstract: Diabetic retinopathy is a leading cause of blindness worldwide, characterized by neurovascular dysfunction. This study aimed to investigate the impact of brimonidine, a selective adrenoceptor agonist, on diabetic retinal neurodegeneration, recognizing the critical role of neurodegeneration in diabetic retinopathy. Streptozotocin-induced diabetes was established in adult male Sprague-Dawley rats to mimic diabetic retinopathy. Rats, except non-diabetic control rats, received topical applications of 0.15% brimonidine tartrate (treatment group) or balanced salt solution (diabetic control group) twice daily following diabetes induction. Each group comprised six randomly assigned animals. Retinal samples were analyzed using immunofluorescence staining, apoptosis assay, and western blot. Topical brimonidine treatment reduced apoptosis of retinal ganglion cells at 8 weeks after induction of diabetes (p<0.05). Glial activation induced by diabetes was reduced by brimonidine treatment. Immunoblot and immunofluorescence assay revealed that the decrease in phospho- protein kinase B (AKT) level resulting from diabetes was also attenuated by brimonidine (p<0.05). Furthermore, brimonidine alleviated the decrease in anti-apoptotic proteins [BCL2 apoptosis regulator (BCL2) and BCL-xl] induced by diabetes (p<0.05). Elevation of phospho-p38 mitogen-activated protein kinase (p38MAPK) and p53 in diabetic rats were reduced by brimonidine (p<0.05). Additionally, brimonidine treatment attenuated the upregulation of the pro-apoptotic molecule BCL-2 associated X in retinas of diabetic rats (p<0.05). These findings suggest that topical brimonidine treatment may protect retinal ganglion cells in experimental diabetes by modulating the AKT pathway and reducing pro-apoptotic p38MAPK levels. This presents a potential neuroprotective approach in diabetes, offering the advantage of localized treatment without the added burden of oral medication.\n\nID: 38934389\nTitle: Topical administration of GLP-1 eyedrops improves retinal ganglion cell function by facilitating presynaptic GABA release in early experimental diabetes.\nAbstract: JOURNAL/nrgr/04.03/01300535-202602000-00048/figure1/v/2025-05-05T160104Z/r/image-tiff Diabetic retinopathy is a prominent cause of blindness in adults, with early retinal ganglion cell loss contributing to visual dysfunction or blindness. In the brain, defects in \u03b3-aminobutyric acid synaptic transmission are associated with pathophysiological and neurodegenerative disorders, whereas glucagon-like peptide-1 has demonstrated neuroprotective effects. However, it is not yet clear whether diabetes causes alterations in inhibitory input to retinal ganglion cells and whether and how glucagon-like peptide-1 protects against neurodegeneration in the diabetic retina through regulating inhibitory synaptic transmission to retinal ganglion cells. In the present study, we used the patch-clamp technique to record \u03b3-aminobutyric acid subtype A receptor-mediated miniature inhibitory postsynaptic currents in retinal ganglion cells from streptozotocin-induced diabetes model rats. We found that early diabetes (4 weeks of hyperglycemia) decreased the frequency of GABAergic miniature inhibitory postsynaptic currents in retinal ganglion cells without altering their amplitude, suggesting a reduction in the spontaneous release of \u03b3-aminobutyric acid to retinal ganglion cells. Topical administration of glucagon-like peptide-1 eyedrops over a period of 2 weeks effectively countered the hyperglycemia-induced downregulation of GABAergic mIPSC frequency, subsequently enhancing the survival of retinal ganglion cells. Concurrently, the protective effects of glucagon-like peptide-1 on retinal ganglion cells in diabetic rats were eliminated by topical administration of exendin-9-39, a specific glucagon-like peptide-1 receptor antagonist, or SR95531, a specific antagonist of the \u03b3-aminobutyric acid subtype A receptor. Furthermore, extracellular perfusion of glucagon-like peptide-1 was found to elevate the frequencies of GABAergic miniature inhibitory postsynaptic currents in both ON- and OFF-type retinal ganglion cells. This elevation was shown to be mediated by activation of the phosphatidylinositol-phospholipase C/inositol 1,4,5-trisphosphate receptor/Ca 2+ /protein kinase C signaling pathway downstream of glucagon-like peptide-1 receptor activation. Moreover, multielectrode array recordings revealed that glucagon-like peptide-1 functionally augmented the photoresponses of ON-type retinal ganglion cells. Optomotor response tests demonstrated that diabetic rats exhibited reductions in visual acuity and contrast sensitivity that were significantly ameliorated by topical administration of glucagon-like peptide-1. These results suggest that glucagon-like peptide-1 facilitates the release of \u03b3-aminobutyric acid onto retinal ganglion cells through the activation of glucagon-like peptide-1 receptor, leading to the de-excitation of retinal ganglion cell circuits and the inhibition of excitotoxic processes associated with diabetic retinopathy. Collectively, our findings indicate that the \u03b3-aminobutyric acid system has potential as a therapeutic target for mitigating early-stage diabetic retinopathy. Furthermore, the topical administration of glucagon-like peptide-1 eyedrops represents a non-invasive and effective treatment approach for managing early-stage diabetic retinopathy.\n\nID: 38921697\nTitle: Clinical observations and mechanistic insights of traditional Chinese medicine in the management of diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR) is one of the leading causes of vision impairment and blindness among diabetic patients globally. Despite advancements in conventional treatments, the quest for more holistic approaches and fewer side effects persists. Traditional Chinese medicine (TCM) has been used for centuries in managing various diseases, including diabetes and its complications. This review evaluated the efficacy and underlying mechanisms of TCM in the management of DR, providing information on its potential integration with conventional treatment methods. A comprehensive literature review was conducted using PubMed, Web of Science, and the China National Knowledge Infrastructure (CNKI) with the search terms 'traditional Chinese medicine', 'diabetic retinopathy', 'clinical efficacies' and their combinations. Studies published before 2023 without language restriction were included, focusing on clinical trials and observational studies that assessed the effectiveness of TCM in DR treatment. The review synthesized evidence of empirical traditional Chinese formulas, traditional Chinese patent medicines, and isolated phytochemicals on DR treatment. The key mechanisms identified included the reduction of oxidative stress, inflammation, and neovascularization, as well as the improvement in neurovascular functionality and integrity of the retinal blood barrier. TCM shows promising potential to manage DR. More large-scale, randomized controlled trials are recommended to validate these findings and facilitate the integration of TCM into mainstream DR treatment protocols.\n\nID: 38911030\nTitle: The Role and Therapeutic Potential of Melatonin in Degenerative Fundus Diseases: Diabetes Retinopathy and Age-Related Macular Degeneration.\nAbstract: Degenerative fundus disease encompasses a spectrum of ocular diseases, including diabetic retinopathy (DR) and age-related macular degeneration (AMD), which are major contributors to visual impairment and blindness worldwide. The development and implementation of effective strategies for managing and preventing the onset and progression of these diseases are crucial for preserving patients' visual acuity. Melatonin, a neurohormone primarily produced by the pineal gland, exhibits properties such as circadian rhythm modulation, antioxidant activity, anti-inflammatory effects, and neuroprotection within the ocular environment. Furthermore, melatonin has been shown to suppress neovascularization and reduce vascular leakage, both of which are critical in the pathogenesis of degenerative fundus lesions. Consequently, melatonin emerges as a promising therapeutic candidate for degenerative ocular diseases. This review provides a comprehensive overview of melatonin synthesis, its localization within ocular tissues, and its mechanisms of action, particularly in regulating melatonin production, thereby underscoring its potential as a therapeutic agent for degenerative fundus diseases.\n\nID: 38474360\nTitle: Neuroprotective and Anti-Inflammatory Activities of Hybrid Small-Molecule SA-10 in Ischemia/Reperfusion-Induced Retinal Neuronal Injury Models.\nAbstract: Embolism, hyperglycemia, high intraocular pressure-induced increased reactive oxygen species (ROS) production, and microglial activation result in endothelial/retinal ganglion cell death. Here, we conducted in vitro and in vivo ischemia/reperfusion (I/R) efficacy studies of a hybrid antioxidant-nitric oxide donor small molecule, SA-10, to assess its therapeutic potential for ocular stroke. To induce I/R injury and inflammation, we subjected R28 and primary microglial cells to oxygen glucose deprivation (OGD) for 6 h in vitro or treated these cells with a cocktail of TNF-\u03b1, IL-1\u03b2 and IFN-\u03b3 for 1 h, followed by the addition of SA-10 (10 \u00b5M). Inhibition of microglial activation, ROS scavenging, cytoprotective and anti-inflammatory activities were measured. In vivo I/R-injured mouse retinas were treated with either PBS or SA-10 (2%) intravitreally, and pattern electroretinogram (ERG), spectral-domain optical coherence tomography, flash ERG and retinal immunocytochemistry were performed. SA-10 significantly inhibited microglial activation and inflammation in vitro. Compared to the control, the compound SA-10 significantly attenuated cell death in both microglia (43% vs. 13%) and R28 cells (52% vs. 17%), decreased ROS (38% vs. 68%) production in retinal microglia cells, preserved neural retinal function and increased SOD1 in mouse eyes. SA-10 is protective to retinal neurons by decreasing oxidative stress and inflammatory cytokines.\n\nID: 38318138\nTitle: Compound Danshen dripping pills prevent early diabetic retinopathy: roles of vascular protection and neuroprotection.\nAbstract: Introduction: Diabetic retinopathy (DR) represents a major cause of adult blindness, and early discovery has led to significant increase in the number of patients with DR. The drugs currently used for treatment, such as ranibizumab, mainly focus on the middle and late periods of DR, and thus do not meet the clinical need. Here, the potential mechanisms by which compound Danshen Dripping Pills (CDDP) might protect against early DR were investigated. Methods: Db/db mice were used to establish a DR model. The initial weights and HbA1c levels of the mice were monitored, and retinal pathology was assessed by hematoxylin-eosin (HE) staining. The vascular permeability of the retina and thickness of each retinal layer were measured, and electroretinogram were performed together with fundus fluorescein angiography and optical coherence tomography. The levels of inflammatory factors were examined in retinal tissue, as well as those of intercellular adhesion molecule 1 (ICAM-1), IL-6, and monocyte chemoattractant protein 1 (MCP-1) in the serum using ELISA. Immunohistochemistry was used to evaluate levels of vascular endothelial growth factor (VEGF), B-cell lymphoma 2 (Bcl-2), and Bclassociated X protein (Bax). Retinal cell injury and apoptosis were examined by TdT-mediated dUTP Nick End Labeling (TUNEL) assays. Results: The data showed that CDDP significantly improved cellular disarrangement. Imaging data indicated that CDDP could reduce vascular permeability and the amplitude of oscillatory potentials (OPs), and restore the thickness of the ganglion cell layer. Moreover, CDDP reduced the expression levels of inflammatory factors in both the retina and serum. Conclusion: These findings strongly suggest that CDDP prevents early DR through vascular and neuroprotection.\n\nID: 38311721\nTitle: Fractalkine isoforms differentially regulate microglia-mediated inflammation and enhance visual function in the diabetic retina.\nAbstract: Diabetic retinopathy (DR) affects about 200 million people worldwide, causing leakage of blood components into retinal tissues, leading to activation of microglia, the resident phagocytes of the retina, promoting neuronal and vascular damage. The microglial receptor, CX3CR1, binds to fractalkine (FKN), an anti-inflammatory chemokine that is expressed on neuronal membranes (mFKN), and undergoes constitutive cleavage to release a soluble domain (sFKN). Deficiencies in CX3CR1 or FKN showed increased microglial activation, inflammation, vascular damage, and neuronal loss in experimental mouse models. To understand the mechanism that regulates microglia function, recombinant adeno-associated viral vectors (rAAV) expressing mFKN or sFKN were delivered to intact retinas prior to diabetes. High-resolution confocal imaging and mRNA-seq were used to analyze microglia morphology and markers of expression, neuronal and vascular health, and inflammatory mediators. We confirmed that prophylactic intra-vitreal administration of rAAV expressing sFKN (rAAV-sFKN), but not mFKN (rAAV-mFKN), in FKNKO retinas provided vasculo- and neuro-protection, reduced microgliosis, mitigated inflammation, improved overall optic nerve health by regulating microglia-mediated inflammation, and prevented fibrin(ogen) leakage at 4 weeks and 10 weeks of diabetes induction. Moreover, administration of sFKN improved visual acuity. Our results elucidated a novel intervention via sFKN gene therapy that provides an alternative pathway to implement translational and therapeutic approaches, preventing diabetes-associated blindness.\n\nID: 37629100\nTitle: Neurovascular Cell Death and Therapeutic Strategies for Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) is a major complication of diabetes and a leading cause of blindness worldwide. DR was recently defined as a neurovascular disease associated with tissue-specific neurovascular impairment of the retina in patients with diabetes. Neurovascular cell death is the main cause of neurovascular impairment in DR. Thus, neurovascular cell protection is a potential therapy for preventing the progression of DR. Growing evidence indicates that a variety of cell death pathways, such as apoptosis, necroptosis, ferroptosis, and pyroptosis, are associated with neurovascular cell death in DR. These forms of regulated cell death may serve as therapeutic targets for ameliorating the pathogenesis of DR. This review focuses on these cell death mechanisms and describes potential therapies for the treatment of DR that protect against neurovascular cell death.\n\nID: 37432261\nTitle: Branched-Chain Amino Acids Metabolism and Their Roles in Retinopathy: From Relevance to Mechanism.\nAbstract: Retinopathy is one of the leading causes of irreversible blindness and vision loss worldwide. Imbalanced nutrients play important roles in the pathogenesis and pathophysiology of retinal diseases. Branched-Chain Amino Acids (BCAAs), as essential amino acids, perform a variety of biological functions, including protein synthesis, glucose metabolism, lipid metabolism, inflammation, and oxidative stress in metabolic tissues of diabetes and aging-related diseases. Recently, it has been shown that BCAAs are highly related to neuroprotection, oxidative stress, inflammatory and glutamate toxicity in the retina of retinopathy. Therefore, this review summarizes the alterations of BCAA levels in retinopathy, especially diabetic retinopathy and aging-related macular disease, and the genetics, functions, and mechanisms of BCAAs in the retina as well as other metabolic tissues for reference. All of these efforts aim to provide fundamental knowledge of BCAAs for further discoveries and research on retina health based on the sensing and signaling of essential amino acids.\n\nID: 37371967\nTitle: New Insights on Dietary Polyphenols for the Management of Oxidative Stress and Neuroinflammation in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) is a neurodegenerative and vascular pathology that is considered one of the leading causes of blindness worldwide, resulting from complications of advanced diabetes mellitus (DM). Current therapies consist of protocols aiming to alleviate the existing clinical signs associated with microvascular alterations limited to the advanced disease stages. In response to the low resolution and limitations of the DR treatment, there is an urgent need to develop more effective alternative therapies to optimize glycemic, vascular, and neuronal parameters, including the reduction in the cellular damage promoted by inflammation and oxidative stress. Recent evidence has shown that dietary polyphenols reduce oxidative and inflammatory parameters of various diseases by modulating multiple cell signaling pathways and gene expression, contributing to the improvement of several chronic diseases, including metabolic and neurodegenerative diseases. However, despite the growing evidence for the bioactivities of phenolic compounds, there is still a lack of data, especially from human studies, on the therapeutic potential of these substances. This review aims to comprehensively describe and clarify the effects of dietary phenolic compounds on the pathophysiological mechanisms involved in DR, especially those of oxidative and inflammatory nature, through evidence from experimental studies. Finally, the review highlights the potential of dietary phenolic compounds as a prophylactic and therapeutic strategy and the need for further clinical studies approaching the efficacy of these substances in DR management.\n\nID: 37298544\nTitle: Current Treatments for Diabetic Macular Edema.\nAbstract: Diabetic retinopathy is a major retinal disorder and a leading cause of blindness. Diabetic macular edema (DME) is an ocular complication in patients with diabetes, and it can impair vision significantly. DME is a disorder of the neurovascular system, and it causes obstructions of the retinal capillaries, damage of the blood vessels, and hyperpermeability due to the expression and action of vascular endothelial growth factor (VEGF). These changes result in hemorrhages and leakages of the serous components of blood that result in failures of the neurovascular units (NVUs). Persistent edema of the retina around the macula causes damage to the neural cells that constitute the NVUs resulting in diabetic neuropathy of the retina and a reduction in vision quality. The macular edema and NVU disorders can be monitored by optical coherence tomography (OCT). Neuronal cell death and axonal degeneration are irreversible, and their development can result in permanent visual loss. Treating the edema before these changes are detected in the OCT images is necessary for neuroprotection and maintenance of good vision. This review describes the effective treatments for the macular edema that are therefore neuroprotective.\n\nID: 37028118\nTitle: Elucidating glial responses to products of diabetes-associated systemic dyshomeostasis.\nAbstract: Diabetic retinopathy (DR) is a leading cause of blindness in working age adults. DR has non-proliferative stages, characterized in part by retinal neuroinflammation and ischemia, and proliferative stages, characterized by retinal angiogenesis. Several systemic factors, including poor glycemic control, hypertension, and hyperlipidemia, increase the risk of DR progression to vision-threatening stages. Identification of cellular or molecular targets in early DR events could allow more prompt interventions pre-empting DR progression to vision-threatening stages. Glia mediate homeostasis and repair. They contribute to immune surveillance and defense, cytokine and growth factor production and secretion, ion and neurotransmitter balance, neuroprotection, and, potentially, regeneration. Therefore, it is likely that glia orchestrate events throughout the development and progression of retinopathy. Understanding glial responses to products of diabetes-associated systemic dyshomeostasis may reveal novel insights into the pathophysiology of DR and guide the development of novel therapies for this potentially blinding condition. In this article, first, we review normal glial functions and their putative roles in the development of DR. We then describe glial transcriptome alterations in response to systemic circulating factors that are upregulated in patients with diabetes and diabetes-related comorbidities; namely glucose in hyperglycemia, angiotensin II in hypertension, and the free fatty acid palmitic acid in hyperlipidemia. Finally, we discuss potential benefits and challenges associated with studying glia as targets of DR therapeutic interventions. In vitro stimulation of glia with glucose, angiotensin II and palmitic acid suggests that: 1) astrocytes may be more responsive than other glia to these products of systemic dyshomeostasis; 2) the effects of hyperglycemia on glia are likely to be largely osmotic; 3) fatty acid accumulation may compound DR pathophysiology by promoting predominantly proinflammatory and proangiogenic transcriptional alterations of macro and microglia; and 4) cell-targeted therapies may offer safer and more effective avenues for DR treatment as they may circumvent the complication of pleiotropism in retinal cell responses. Although several molecules previously implicated in DR pathophysiology are validated in this review, some less explored molecules emerge as potential therapeutic targets. Whereas much is known regarding glial cell activation, future studies characterizing the role of glia in DR and how their activation is regulated and sustained (independently or as part of retinal cell networks) may help elucidate mechanisms of DR pathogenesis and identify novel drug targets for this blinding disease.\n\nID: 36517889\nTitle: Models of microglia depletion and replenishment elicit protective effects to alleviate vascular and neuronal damage in the diabetic murine retina.\nAbstract: Microglia, the resident phagocytes of the retina, are believed to influence the development of retinopathy, but their exact contributions to vascular integrity and neuronal loss are unknown. Therefore, utilizing two models of microglia depletion, we aimed to deplete and repopulate microglia to clarify the contribution of microglia to neuronal loss and vascular damage in the diabetic retina in an STZ-induced model of hyperglycemia. Here, we report that 2\u00a0weeks exposure to diphtheria toxin (DTx) in diabetic CX3CR1CreER:R26iDTR transgenic mice induced a 62% increase in Iba1+ microglia associated with an increase in TUJ1+ axonal density and prevention of NeuN+RBPMS+ neuronal loss. Conversely, diabetic PBS controls exhibited robust TUJ1+ axonal and NeuN+RBPMS+ neuronal loss compared to non-diabetic controls. A 2-week recovery period from DTx was associated with a 40% reduction in angiogenesis and an 85% reduction in fibrinogen deposition into the diabetic retina in comparison to diabetic PBS-treated controls. Analysis of microglia morphology and marker expression revealed that following a 2-week recovery period microglia displayed a P2RY12+Ly6C- phenotype and high transformation index (TI) values complimented by a ramified-surveillant morphology closely resembling non-diabetic controls. In contrast, diabetic PBS-treated control mice displayed P2RY12+Ly6C+ microglia, with a 50% reduction in TI values with an amoeboid morphology. To validate these observations were due to microglia depletion, we used PLX-5622 to assess vascular and neuronal damage in the retinas of diabetic mice. Confocal microscopy revealed that PLX-5622 also induced an increase in TUJ1+ axonal density and prevented fibrinogen extravasation into the diabetic retina. mRNAseq gene expression analysis in retinal isolates revealed that PLX-5622-induced microglia depletion and repopulation induced a downregulation in genes associated with microglial activation and phagocytosis, B2m, Cx3cr1, and Trem2, and complement-associated synaptic pruning, C1qa, C1qb, and C1qc. Although the levels of microglia depletion induced with DTx in the CX3CR1CreER:R26iDTR model and those induced with the CSF-1R antagonists are distinct, our results suggest that microglia depletion and replenishment is neuroprotective by inducing the proliferation of a homeostatic microglia pool that supports neuronal and vascular integrity.\n\nID: 36463857\nTitle: Retinal Neurodegeneration in Euglycemic Hyperinsulinemia, Prediabetes, and Diabetes.\nAbstract: Diabetic retinopathy (DR) is a challenging public health problem mainly because of its growing prevalence and risk of blindness. In general, our current knowledge and practice have failed to prevent the onset or progression of DR to sight-threatening complications. While there are treatment options for sight-threatening complications of DR, it is crucial to pay more attention to the early stages of DR to decrease its prevalence. Growing evidence suggests many pathologic changes occur before clinical presentations of DR in euglycemic hyperinsulinemia, prediabetes, and diabetes. These pathological changes occur in retinal neurons, glia, and microvasculature. A new focus on these preclinical pathologies - especially on hyperinsulinemia - may provide further insight into disease mechanisms, endpoints for clinical trials, and druggable targets in early disease. Here, we review the current evidence on the pathophysiological changes reported in preclinical DR and appraise preventive and treatment options for DR.\n\nID: 36046456\nTitle: HDAC3 Inhibition Alleviates High-Glucose-Induced Retinal Ganglion Cell Death through Inhibiting Inflammasome Activation.\nAbstract: The exact effects of histone deacetylase 3 (HDAC3) inhibition in DR related retinal ganglion cells (RGCs) death remained unclear. This study is aimed at detecting the influence of HDAC3 on the high-glucose-induced retinal ganglion cell death. The retinal HDAC3 expression in DR of different time points was analyzed by immunohistochemical assay and western blot. Besides, the expression of HDAC3 and both retinal thickness and RGC loss were analyzed. The effects of HDAC3 inhibitor on cell viability, oxidative stress, and apoptosis in high-glucose- (HG-) treated RGCs were analyzed. Both inflammatory and antioxidative factors were detected by ELISA. Advanced effects of HDAC3 inhibition on the expression of NLRP3 inflammasome were detected using western blots. High HDAC3 expression was detected only in the late DR mice (4 months of diabetes duration) but not early DR mice (2 months of diabetes duration). The immunohistochemical assay showed that HDAC3 expression was correlated with both retinal thickness and RCG contents. HDAC3 inhibitor significantly protected the HG-treated RGCs from damaged cell viability, severe apoptosis, and oxidative stress. Advanced pathway analyses showed that HDAC3 inhibition inactivated NLRP3 inflammasome and thus alleviated retinal inflammation. Conclusion. In conclusion, HDAC3 was involved in RGC loss and thus promoted the progression of neurodegeneration of DR. Besides, HDAC3 inhibitor demonstrated protective effects in neurodegeneration in DR through downregulation of NLRP3 activity. The effects of HDAC3 inhibitor in DR management should be confirmed in clinical trials.\n\nID: 35955655\nTitle: New Insights into Treating Early and Advanced Stage Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) is the leading cause of preventable blindness in the working-age population. The disease progresses slowly, and we can roughly differentiate two stages: early-stage (ESDR), in which there are mild retinal lesions and visual acuity is generally preserved, and advanced-stage (ASDR), in which the structural lesions are significant and visual acuity is compromised. At present, there are no specific treatments for ESDR and the current recommended action is to optimize metabolic control and maintain close control of blood pressure. However, in the coming years, it is foreseeable that therapeutic strategies based in neuroprotection will be introduced in the clinical arena. This means that screening aimed at identifying patients in whom neuroprotective treatment might be beneficial will be crucial. Regarding the treatment of ASDR, the current primary course is based on laser photocoagulation and intravitreal injections of anti-angiogenic factors or corticosteroids. Repeated intravitreal injections of anti-VEGF agents as the first-line treatment would be replaced by more cost-effective and personalized treatments based on the results of \"liquid biopsies\" of aqueous humor. Finally, topical administration (i.e., eye drops) of neuroprotective, anti-inflammatory and anti-angiogenic agents will represent a revolution in the treatment of DR in the coming decade. In this article, all these approaches and others will be critically discussed from a holistic perspective.\n\nID: 35533335\nTitle: Diabetic Retinopathy: Role of Neurodegeneration and Therapeutic Perspectives.\nAbstract: Retinal neurodegeneration plays a significant role in the pathogenesis of diabetic retinopathy, the leading cause of preventable blindness. The hallmarks of diabetes-induced neurodegeneration are neural cell apoptosis and glial activation, which seem even before vascular lesions can be detected by ophthalmoscopic examination. The molecular mediators of retinal neurodegeneration include proinflamma- tory cytokines, oxidative stress, mitochondrial dysfunction, and the molecular pathways closely related to chronic hyperglycemia. In this article, an overview of the main components of neurodegeneration, its key underlying mechanisms, and the more useful experimental models for investigative purposes will be given. In addition, the results of most relevant treatments based on neuroprotection, and the research gaps that should be filled will be critically reviewed.\n\nID: 35264926\nTitle: Glucagon-Like Peptide 1 Receptor Agonists - Potential Game Changers in the Treatment of Glaucoma?\nAbstract: Glaucoma is a common ocular neurodegenerative disease characterized by the progressive loss of retinal ganglion cells and their axons. It is the most common cause of irreversible blindness. With an increasing number of glaucoma patients and disease progression despite treatment, it is paramount to develop new and effective therapeutics. Emerging new candidates are the receptor agonists of the incretin hormone glucagon-like-peptide-1 (GLP-1), originally used for the treatment of diabetes. GLP-1 receptor (GLP-1R) agonists have shown neuroprotective effects in preclinical and clinical studies on neurodegenerative diseases in both the brain (e.g., Alzheimer's disease, Parkinson's disease, stroke and diabetic neuropathy) and the eye (e.g., diabetic retinopathy and AMD). However, there are currently very few studies investigating the protective effects of GLP-1R agonists in the treatment of specifically glaucoma. Based on a literature search on PubMed, the Cochrane Library, and ClinicalTrials.gov, this review aims to summarize current clinical literature on GLP-1 receptor agonists in the treatment of neurodegenerative diseases to elucidate their potential in future anti-glaucomatous treatment strategies.\n\nID: 35246694\nTitle: Baccharin from Brazilian green propolis induces neurotrophic signaling pathways in PC12 cells: potential for axonal and synaptic regeneration.\nAbstract: Neurodegenerative diseases are characterized by progressive loss of the structure and function of specific neuronal populations, and have been associated with reduced neurotrophic support. Neurotrophins, like NGF (nerve growth factor), are endogenous proteins that induce neuritogenesis and modulate axonal growth, branching, and synapsis; however, their therapeutic application is limited mainly by low stability, short half-life, and inability to cross the blood-brain barrier (BBB). Small neurotrophic molecules that have suitable pharmacokinetics and are able to cross the BBB are potential candidates for neuroprotection. Baccharin is a bioactive small molecule isolated from Brazilian green propolis. In the present study, we investigated the neurotrophic and neuroprotective potential of baccharin in the PC12 cell neuronal model. We used pharmacological inhibitors (K252a, LY294002, and U0126), and ELISA (phospho-trkA, phospho-Akt, and phospho-MEK) to investigate the involvement of trkA receptor, PI3k/Akt pathway, and MAPK/Erk pathway, respectively. Additionally, we evaluated the expression of axonal (GAP-43) and synaptic (synapsin I) proteins by western blot. The results showed that baccharin induces neuritogenesis in NGF-deprived PC12 cells, through activation of trkA receptor and the downstream signaling cascades (PI3K/Akt and MAPK/ERK), which is the same neurotrophic pathway activated by NGF in PC12 cells and neurons. Baccharin also induced the expression of GAP-43 and synapsin I, which mediate axonal and synaptic plasticity, respectively. Additionally, in silico predictions of baccharin showed favorable physicochemical properties, pharmacokinetics, drug-likeness, and medicinal chemistry friendliness. Altogether, these findings suggest that baccharin is a promising neurotrophic agent whose therapeutic application in neurodegeneration should be further investigated.\n\nID: 35178992\nTitle: [Protective effect of ginsenoside Rg_1 aganist diabetic retinopathy by inhibiting NLRP3 inflammasome in type 2 diabetic mice].\nAbstract: Ginsenoside Rg_1, one of the main active components of precious traditional Chinese medicine Ginseng Radix et Rhizoma, has the anti-oxidative stress, anti-inflammation, anti-aging, neuroprotection, and other pharmacological effects. Diabetic retinopathy(DR), the most common complication of diabetes, is also the main cause of impaired vision and blindness in the middle-aged and the elderly. The latest research shows that ginsenoside Rg_1 can protect patients against DR, but the protection and the mechanism are rarely studied. This study mainly explored the protective effect of ginsenoside Rg_1 against DR in type 2 diabetic mice and the mechanism. High fat diet(HFD) and streptozotocin(STZ) were used to induce type 2 diabetes in mice, and hematoxylin-eosin(HE) staining was employed to observe pathological changes in the retina of mice. The immunohistochemistry was applied to study the localization and expression of nucleotide-binding oligomerization domain-like receptors 3(NLRP3) and vascular endothelial growth factor(VEGF) in retina, and Western blot was used to detect the expression of nuclear factor-kappa B(NF-\u03baB), p-NF-\u03baB, NLRP3, caspase-1, interleukin-1\u03b2(IL-1\u03b2), transient receptor potential channel protein 6(TRPC6), nuclear factor of activated T-cell 2(NFAT2), and VEGF in retina. The results showed that ginsenoside Rg_1 significantly alleviated the pathological injury of retina in type 2 diabetic mice. Immunohistochemistry results demonstrated that ginsenoside Rg_1 significantly decreased the expression of NLRP3 and VEGF in retinal ganglion cells, middle plexiform layer, and outer plexiform layer in type 2 diabetic mice. According to the Western blot results, ginsenoside Rg_1 significantly lowered the expression of p-NF-\u03baB, NLRP3, caspase-1, IL-1\u03b2, TRPC6, NFAT2, and VEGF in retina of type 2 diabetic mice. These findings suggest that ginsenoside Rg_1 can significantly alleviate DR in type 2 diabetic mice, which may be related to inhibition of NLRP3 inflammasome and VEGF. This study provides experimental evidence for the clinical application of ginsenoside Rg_1 in the treatment of DR.\n\nID: 35044228\nTitle: Influences of Glaucoma on the Structure and Function of Synapses in the Visual System.\nAbstract: Significance: Glaucoma is an age-related neurodegenerative disorder of the visual system associated with sensitivity to intraocular pressure (IOP). It is the leading irreversible cause of vision loss worldwide, and vision loss results from damage and dysfunction of the retinal output neurons known as retinal ganglion cells (RGCs). Recent Advances: Elevated IOP and optic nerve injury triggers pruning of RGC dendrites, altered morphology of excitatory inputs from presynaptic bipolar cells, and disrupted RGC synaptic function. Less is known about RGC outputs, although evidence to date indicates that glaucoma is associated with altered mitochondrial and synaptic structure and function in RGC-projection targets in the brain. These early functional changes likely contribute to vision loss and might be a window into early diagnosis and treatment. Critical Issues: Glaucoma affects different RGC populations to varying extents and along distinct time courses. The influence of glaucoma on RGC synaptic function as well as the mechanisms underlying these effects remain to be determined. Since RGCs are an especially energetically demanding population of neurons, altered intracellular axon transport of mitochondria and mitochondrial function might contribute to RGC synaptic dysfunction in the retina and brain as well as RGC vulnerability in glaucoma. Future Directions: The mechanisms underlying differential RGC vulnerability remain to be determined. Moreover, the timing and mechanisms of RGCs synaptic dysfunction and degeneration will provide valuable insight into the disease process in glaucoma. Future work will be able to capitalize on these findings to better design diagnostic and therapeutic approaches to detect disease and prevent vision loss. Antioxid. Redox Signal. 37, 842-861.\n\nID: 34371951\nTitle: A Systematic Review of Carotenoids in the Management of Diabetic Retinopathy.\nAbstract: Diabetic retinopathy, which was primarily regarded as a microvascular disease, is the leading cause of irreversible blindness worldwide. With obesity at epidemic proportions, diabetes-related ocular problems are exponentially increasing in the developed world. Oxidative stress due to hyperglycemic states and its associated inflammation is one of the pathological mechanisms which leads to depletion of endogenous antioxidants in retina in a diabetic patient. This contributes to a cascade of events that finally leads to retinal neurodegeneration and irreversible vision loss. The xanthophylls lutein and zeaxanthin are known to promote retinal health, improve visual function in retinal diseases such as age-related macular degeneration that has oxidative damage central in its etiopathogenesis. Thus, it can be hypothesized that dietary supplements with xanthophylls that are potent antioxidants may regenerate the compromised antioxidant capacity as a consequence of the diabetic state, therefore ultimately promoting retinal health and visual improvement. We performed a comprehensive literature review of the National Library of Medicine and Web of Science databases, resulting in 341 publications meeting search criteria, of which, 18 were found eligible for inclusion in this review. Lutein and zeaxanthin demonstrated significant protection against capillary cell degeneration and hyperglycemia-induced changes in retinal vasculature. Observational studies indicate that depletion of xanthophyll carotenoids in the macula may represent a novel feature of DR, specifically in patients with type 2 or poorly managed type 1 diabetes. Meanwhile, early interventional trials with dietary carotenoid supplementation show promise in improving their levels in serum and macular pigments concomitant with benefits in visual performance. These findings provide a strong molecular basis and a line of evidence that suggests carotenoid vitamin therapy may offer enhanced neuroprotective effects with therapeutic potential to function as an adjunct nutraceutical strategy for management of diabetic retinopathy.\n\nID: 34289359\nTitle: \u03b12\u03b4-1 switches the phenotype of synaptic AMPA receptors by physically disrupting heteromeric subunit assembly.\nAbstract: Many neurological disorders show an increased prevalence of GluA2-lacking, Ca2+-permeable AMPA receptors (CP-AMPARs), which dramatically alters synaptic function. However, the molecular mechanism underlying this distinct synaptic plasticity remains enigmatic. Here, we show that nerve injury potentiates postsynaptic, but not presynaptic, CP-AMPARs in the spinal dorsal horn via \u03b12\u03b4-1. Overexpressing \u03b12\u03b4-1, previously regarded as a Ca2+ channel subunit, augments CP-AMPAR levels at the cell surface and synapse. Mechanistically, \u03b12\u03b4-1 physically interacts with both GluA1 and GluA2 via its C terminus, inhibits the GluA1/GluA2 heteromeric assembly, and increases GluA2 retention in the endoplasmic reticulum. Consequently, \u03b12\u03b4-1 diminishes the availability and synaptic expression of GluA1/GluA2 heterotetramers in the spinal cord in neuropathic pain. Inhibiting \u03b12\u03b4-1 with gabapentin or disrupting the \u03b12\u03b4-1-AMPAR complex fully restores the intracellular assembly and synaptic dominance of heteromeric GluA1/GluA2 receptors. Thus, \u03b12\u03b4-1 is a pivotal AMPAR-interacting protein that controls the subunit composition and Ca2+ permeability of postsynaptic AMPARs.\n\nID: 33666886\nTitle: The Neurotrophic-Like Effect of Carvacrol: Perspective for Axonal and Synaptic Regeneration.\nAbstract: Carvacrol (CARV) is a phytochemical widely used as flavoring, preservative, and fragrance in food and cosmetic industries. CARV is able to cross the blood-brain barrier (BBB) and has demonstrated protective potential against neurodegenerative diseases by several mechanisms, including antioxidant, anti-inflammatory, anticholinesterase, and antiapoptotic effects. However, it is not known whether CARV is able to modulate axonal and synaptic plasticity, crucial events in cognition, memory, and learning. Abnormalities in axonal and synaptic plasticity, low levels of neurotrophins, and bioenergetic failure have been associated with the pathogenesis of neurodegenerative diseases, including Parkinson's (PD) and Alzheimer's diseases (ADs). Small lipophilic molecules with neurotrophic activity might be able to restore the axonal and synaptic networks that are lost in neurodegenerative processes. Therefore, this study investigated the neurotrophic potential of CARV in PC12 cell-based neuronal model. Carvacrol induced neurite outgrowth by activating the NGF high-affinity trkA receptor and the downstream PI3K-AKT and MAPK-ERK pathways, without depending on NGF. In addition, CARV increased the expression of proteins involved in neuronal plasticity (\u03b2-tubulin III, F-actin, 200-kDa neurofilament, GAP-43 and synapsin-I) and improved bioenergetics (AMPK\u03b1, p-AMPK\u03b1, and ATP). Our study showed, for the first time, a promising neurotrophic mechanism of CARV that could be beneficial in neurodegenerative and neurological diseases.\n\nID: 33617967\nTitle: Xuesaitong exerts long-term neuroprotection for stroke recovery by inhibiting the ROCKII pathway, in vitro and in vivo.\nAbstract: Xuesaitong (XST) is a traditional Chinese medicine injection with neuroprotective properties and has been extensively used to treat stroke for many years. The main component of XST is Panax notoginseng saponins (PNS), which is the main extract of the Chinese herbal medicine Panax notoginseng. In this study, we investigated whether XST provided long-term neuroprotection by inhibiting neurite outgrowth inhibitor-A (Nogo-A) and the ROCKII pathway in experimental rats after middle cerebral artery occlusion (MCAO) and in SH-SY5Y cells exposed to oxygen-glucose deprivation/reperfusion (OGD/R). Rats with permanent MCAO were administered XST, Y27632, XST plus Y27632, and nimodipine for 14 and 28 days. Successful MCAO onset was confirmed by 2,3,5-triphenyl tetrazolium chloride (TTC) staining. Neurological deficit score (NDS) was used to assess neurological impairment. Hematoxylin-eosin (HE) staining and immunohistochemical (IHC) analysis of synaptophysin (SYN) and postsynaptic density protein-95 (PSD-95) were performed to evaluate cerebral ischemic injury and the neuroprotective capability of XST. Nogo-A levels and the ROCKII pathway were detected by IHC analysis, western blotting, and quantitative real-time polymerase chain reaction (qRT-PCR) to explore the protective mechanism of XST. OGD/R model was established in SH-SY5Y cells. Cell counting kit 8 (CCK8) was applied to detect the optimum OGD time and XST concentration. The expression levels Nogo-A and ROCKII pathway were determined using western blotting. Our results showed that XST reduced neurological dysfunction and pathological damage, promoted weight gain and synaptic regeneration, reduced Nogo-A mRNA and protein levels, and inhibited the ROCKII pathway in MCAO rats. CCK8 assay displayed that the optimal OGD time and optimal XST concentration were 7\u00a0h and 20\u00a0\u03bcg/mL respectively in SH-SY5Y cells. XST could evidently inhibit OGD/R-induced Nogo-A protein expression and ROCKII pathway activation in SH-SY5Y cells. The present study suggested that XST exerted long-term neuroprotective effects that assisted in stroke recovery, possibly through inhibition of the ROCKII pathway.\n\nID: 33123308\nTitle: Lipin1 Is Involved in the Pathogenesis of Diabetic Encephalopathy through the PKD/Limk/Cofilin Signaling Pathway.\nAbstract: Diabetic encephalopathy is a type of central diabetic neuropathy resulting from diabetes mainly manifested as cognitive impairments. However, its underlying pathogenesis and effective treatment strategies remain unclear. In the present study, we investigated the effect of Lipin1, a phosphatidic acid phosphatase enzyme, on the pathogenesis of diabetic encephalopathy. We found that in vitro, Lipin1 exerts protective effects on high glucose-induced reductions of PC12 cell viability, while in vivo, Lipin1 is downregulated within the CA1 hippocampal region in a type I diabetes rat model. Increased levels of Lipin1 within the CA1 region are accompanied with protective effects including amelioration of dendritic spine and synaptic deficiencies, phosphorylation of the synaptic plasticity-related proteins, LIM kinase 1 (p-limk1) and cofilin, as well as increases in the synthesis of diacylglycerol (DAG), and the expression of phosphorylated protein kinase D (p-PKD). These effects are associated with the rescue of cognitive disorders as shown in this rat model of diabetes. In contrast, knockdown of Lipin1 within the CA1 region enhanced neuronal abnormalities and the genesis of cognitive impairment in rats. These results suggest that Lipin1 may exert neuroprotective effects involving the PKD/Limk/Cofilin signaling pathway and may serve as a potential therapeutic target for diabetic encephalopathy.\n\nID: 33081260\nTitle: The Benefits of Flavonoids in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR), one of the most common complications of diabetes, is the leading cause of legal blindness among adults of working age in developed countries. After 20 years of diabetes, almost all patients suffering from type I diabetes mellitus and about 60% of type II diabetics have DR. Several studies have tried to identify drugs and therapies to treat DR though little attention has been given to flavonoids, one type of polyphenols, which can be found in high levels mainly in fruits and vegetables, but also in other foods such as grains, cocoa, green tea or even in red wine. Flavonoids have anti-inflammatory, antioxidant and antiviral effects. Since it is known that diabetes induces oxidative stress and inflammation in the retina leading to neuronal death in the early stages of the disease, the use of these compounds can prove to be beneficial in the prevention or treatment of DR. In this review, we summarize the molecular and cellular effects of flavonoids in the diabetic retina.\n\nID: 32676893\nTitle: Carbamazepine conquers spinal GAP43 deficiency and sciatic Nav1.5 upregulation in diabetic mice: novel mechanisms in alleviating allodynia and hyperalgesia.\nAbstract: This work tested the role of carbamazepine in alleviating alloxan-induced diabetic neuropathy and the enhancement of spinal plasticity. Mice were randomized into four groups: normal, control, carbamazepine (25-mg/kg) and carbamazepine (50-mg/kg). Nine weeks after induction of diabetes, symptoms of neuropathy were confirmed and carbamazepine (or vehicle) was given every other day for five weeks. After completing the treatment period, mice were sacrificed and the pathologic features in the spinal cord and the sciatic nerves were determined. The spinal cords were evaluated for synaptic plasticity (growth associated protein-43, GAP43), microglia cell expression (by CD11b) and astrocyte expression (glial fibrillary acidic protein, GFAP). Further, sciatic nerve expression of Nav1.5 was measured. Results revealed that carbamazepine 50\u00a0mg/kg prolonged the withdrawal threshold of von-Frey filaments and increased the hot plate jumping time. Carbamazepine improved the histopathologic pictures of the sciatic nerves and spinal cords. Spinal cord of carbamazepine-treated groups had enhanced expression of GAP43 but lower content of CD11b and GFAP. Furthermore, specimens from the sciatic nerve indicated low expression of Nav1.5. In conclusion, this work provided evidence, for the first time, that the preventive effect of carbamazepine against diabetic neuropathy involves correction of spinal neuronal plasticity and glia cell expression.\n\nID: 32151061\nTitle: Kynurenic Acid Protects Against Ischemia/Reperfusion-Induced Retinal Ganglion Cell Death in Mice.\nAbstract: Glaucoma is an optic neuropathy and involves the progressive degeneration of retinal ganglion cells (RGCs), which leads to blindness in patients. We investigated the role of the neuroprotective kynurenic acid (KYNA) in RGC death against retinal ischemia/reperfusion (I/R) injury. We injected KYNA intravenously or intravitreally to mice. We generated a knockout mouse strain of kynurenine 3-monooxygenase (KMO), an enzyme in the kynurenine pathway that produces neurotoxic 3-hydroxykynurenine. To test the effect of mild hyperglycemia on RGC protection, we used streptozotocin (STZ) induced diabetic mice. Retinal I/R injury was induced by increasing intraocular pressure for 60 min followed by reperfusion and RGC numbers were counted in the retinal flat mounts. Intravenous or intravitreal administration of KYNA protected RGCs against I/R injury. The I/R injury caused a greater loss of RGCs in wild type than in KMO knockout mice. KMO knockout mice had mildly higher levels of fasting blood glucose than wild type mice. Diabetic mice showed significantly lower loss of RGCs when compared with non-diabetic mice subjected to I/R injury. Together, our study suggests that the absence of KMO protects RGCs against I/R injury, through mechanisms that likely involve higher levels of KYNA and glucose.\n\nID: 31649495\nTitle: Neuroprotective Potential of Pituitary Adenylate Cyclase Activating Polypeptide in Retinal Degenerations of Metabolic Origin.\nAbstract: Pituitary adenylate cyclase-activating polypeptide (PACAP1-38) is a highly conserved member of the secretin/glucagon/VIP family. The repressive effect of PACAP1-38 on the apoptotic machinery has been an area of active research conferring a significant neuroprotective potential onto this peptide. A remarkable number of studies suggest its importance in the etiology of neurodegenerative disorders, particularly in relation to retinal metabolic disorders. In our review, we provide short descriptions of various pathological conditions (diabetic retinopathy, excitotoxic retinal injury and ischemic retinal lesion) in which the remedial effect of PACAP has been well demonstrated in various animal models. Of all the pathological conditions, diabetic retinopathy seems to be the most intriguing as it develops in 75% of patients with type 1 and 50% of patients with type 2 diabetes, with concomitant progression to legal blindness in about 5%. Several animal models have been developed in recent years to study retinal degenerations and out of these glaucoma and age-related retina degeneration models bear human recapitulations. PACAP neuroprotection is thought to operate through enhanced cAMP production upon binding to PAC1-R. However, the underlying signaling network that leads to neuroprotection is not fully understood. We observed that (i) PACAP is not equally efficient in the above conditions; (ii) in some cases more than one signaling pathways are activated; (iii) the coupling of PAC1-R and signaling is stage dependent; and (iv) PAC1-R is not the only receptor that must be considered to interpret the effects in our experiments. These observations point to a complex signaling mechanism, that involves alternative routes besides the classical cAMP/protein kinase A pathway to evoke the outstanding neuroprotective action. Consequently, the possible contribution of the other two main receptors (VPAC1-R and VPAC2-R) will also be discussed. Finally, the potential medical use of PACAP in some retinal and ocular disorders will also be reviewed. By taking advantage of, low-cost synthesis technologies today, PACAP may serve as an alternative to the expensive treatment modelities currently available in ocular or retinal conditions.\n\nID: 31530215\nTitle: mTOR activation due to APPL1 deficiency exacerbates hyperalgesia via Rab5/Akt and AMPK signaling pathway in streptozocin-induced diabetic rats.\nAbstract: Painful diabetic neuropathy is a common complication of diabetes mellitus with obscure underlying mechanisms. The adaptor protein APPL1 is critical in mediating the insulin sensitizing and insulin signaling. In neurons, APPL1 reportedly affects synaptic plasticity, while its role in the pathogenesis of painful diabetic neuropathy is masked. Our Western blotting revealed significantly decreased APPL1 expression in the dorsal horn in streptozocin-induced rats versus the control rats, coupled with concomitant mechanical and thermal hyperalgesia. Afterward, the determination of exact localization of APPL1 in spinal cord by immunofluorescent staining assay revealed highly expressed APPL1 in the lamina of spinal dorsal horn in control rats, with the overexpression in neurons, microglia, and underexpression in astrocytes. The APPL1 expression in laminae I and II was significantly downregulated in painful diabetic neuropathy rats. In addition, APPL1 deficiency or overexpression contributed to the increase or decrease of Map and Bassoon, respectively. The localization and immunoactivity of APPL1 and mammalian target of rapamycin (mTOR) were determined in spinal dorsal horn in painful diabetic neuropathy rats and control rats by immunohistochemistry, suggesting pronounced decrease in APPL1 expression in the superficial layer of the spinal cord in painful diabetic neuropathy rats, with p-mTOR expression markedly augmented. APPL1 knockdown by infection with lentiviral vector facilitated the activation of mTOR and abrogated mechanical withdrawal threshold values in painful diabetic neuropathy rats. Genetically overexpressed APPL1 significantly eliminated the activation of mTOR and resulted in the augmented mechanical withdrawal threshold values and thermal withdrawal latency values. Furthermore, the APPL1 levels affect phosphorylation of adenosine monophosphate-activated protein kinase (AMPK), and Akt, as well as the small GTPase, Rab5 expression in painful diabetic neuropathy rats. Our results uncovered a novel mechanism by which APPL1 deficiency facilitates the mTOR activation and thus exacerbates the hyperalgesia in streptozocin-induced diabetic rats, presumably via the regulation of Rab5/Akt and AMPK signaling pathway.\n\nID: 31481518\nTitle: Streptozotocin-Induced Diabetic Neuropathic Pain Is Associated with Potentiated Calcium-Permeable AMPA Receptor Activity in the Spinal Cord.\nAbstract: Neuronal hyperactivity in the spinal dorsal horn can amplify nociceptive input in diabetic neuropathic pain. The glutamate N-methyl-d-aspartate and \u03b1-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptors (NMDA receptors and AMPA receptors, respectively) are involved in spinal nociceptive transmission. It is unclear, however, whether painful diabetic neuropathy is associated with changes in the activity of synaptic NMDA receptors and AMPA receptors in spinal dorsal horn neurons. AMPA receptors lacking GluA2 are Ca2+-permeable (CP-AMPA receptors), and their currents display characteristic inward rectification. In this study, we showed that evoked excitatory postsynaptic currents (EPSCs), induced by streptozotocin, exhibited inward rectification in spinal dorsal neurons in diabetic rats. Presynaptic and postsynaptic NMDA receptor activity in the spinal dorsal horn was similar in diabetic and control rats. In the dorsal spinal cord, the membrane GluA2 protein level was significantly lower in diabetic than in control rats, whereas the cytosolic GluA2 level was greater in diabetic than in control rats. In contrast, the GluA1 subunit levels in the plasma membrane and cytosol did not differ between the two groups. Blocking CP-AMPA receptors significantly reduced the amplitude of EPSCs of dorsal horn neurons in diabetic but not in control rats. Furthermore, blocking spinal CP-AMPA receptors reduced pain hypersensitivity in diabetic rats but had no effect on nociception in control rats. Our study suggests that diabetic neuropathy augments CP-AMPA receptor activity in the spinal dorsal horn by causing intracellular retention of GluA2 and impairing GluA2 membrane trafficking. Increased prevalence of spinal CP-AMPA receptors sustains diabetic neuropathic pain. SIGNIFICANCE STATEMENT: This study demonstrates that the prevalence of synaptic calcium-permeable AMPA receptors is increased in the spinal dorsal horn, which mediates pain hypersensitivity in diabetic neuropathy. Thus, calcium-permeable AMPA receptors play an important role in glutamatergic synaptic plasticity in the spinal cord in painful diabetic neuropathy. This new knowledge improves our understanding of the mechanisms involved in central sensitization associated with diabetic neuropathic pain and suggests that calcium-permeable AMPA receptors are an alternative therapeutic target for treating this chronic pain condition.\n\nID: 31207342\nTitle: Spermine oxidase: A promising therapeutic target for neurodegeneration in diabetic retinopathy.\nAbstract: Diabetic Retinopathy (DR), is a significant public health issue and the leading cause of blindness in working-aged adults worldwide. The vision loss associated with DR affects patients' quality of life and has negative social and psychological effects. In the past, diabetic retinopathy was considered as a vascular disease; however, it is now recognized to be a neuro-vascular disease of the retina. Current therapies for DR, such as laser photocoagulation and anti-VEGF therapy, treat advanced stages of the disease, particularly the vasculopathy and have adverse side effects. Unavailability of effective treatments to prevent the incidence or progression of DR is a major clinical problem. There is a great need for therapeutic interventions capable of preventing retinal damage in DR patients. A growing body of evidence shows that neurodegeneration is an early event in DR pathogenesis. Therefore, studies of the underlying mechanisms that lead to neurodegeneration are essential for identifying new therapeutic targets in the early stages of DR. Deregulation of the polyamine metabolism is implicated in various neurodegenerative diseases, cancer, renal failure, and diabetes. Spermine Oxidase (SMOX) is a highly inducible enzyme, and its dysregulation can alter polyamine homeostasis. The oxidative products of polyamine metabolism are capable of inducing cell damage and death. The current review provides insight into the SMOX-regulated molecular mechanisms of cellular damage and dysfunction, and its potential as a therapeutic target for diabetic retinopathy. Structural and functional changes in the diabetic retina and the mechanisms leading to neuronal damage (excitotoxicity, loss of neurotrophic factors, oxidative stress, mitochondrial dysfunction etc.) are also summarized in this review. Furthermore, existing therapies and new approaches to neuroprotection are discussed.\n\nID: 31061088\nTitle: Limiting Neuronal Nogo Receptor 1 Signaling during Experimental Autoimmune Encephalomyelitis Preserves Axonal Transport and Abrogates Inflammatory Demyelination.\nAbstract: We previously identified that ngr1 allele deletion limits the severity of experimental autoimmune encephalomyelitis (EAE) by preserving axonal integrity. However, whether this favorable outcome observed in EAE is a consequence of an abrogated neuronal-specific pathophysiological mechanism, is yet to be defined. Here we show that, Cre-loxP-mediated neuron-specific deletion of ngr1 preserved axonal integrity, whereas its re-expression in ngr1-/- female mice potentiated EAE-axonopathy. As a corollary, myelin integrity was preserved under Cre deletion in ngr1flx/flx , retinal ganglion cell axons whereas, significant demyelination occurred in the ngr1-/- optic nerves following the re-introduction of NgR1. Moreover, Cre-loxP-mediated axon-specific deletion of ngr1 in ngr1flx/flx mice also demonstrated efficient anterograde transport of fluorescently-labeled ChTx\u03b2 in the optic nerves of EAE-induced mice. However, the anterograde transport of ChTx\u03b2 displayed accumulation in optic nerve degenerative axons of EAE-induced ngr1-/- mice, when NgR1 was reintroduced but was shown to be transported efficiently in the contralateral non- recombinant adeno-associated virus serotype 2-transduced optic nerves of these mutant mice. We further identified that the interaction between the axonal motor protein, Kinesin-1 and collapsin response mediator protein 2 (CRMP2) was unchanged upon Cre deletion of ngr1 Whereas, this Kinesin-1/CRMP2 association was reduced when NgR1 was re-expressed in the ngr1-/- optic nerves. Our data suggest that NgR1 governs axonal degeneration in the context of inflammatory-mediated demyelination through the phosphorylation of CRMP2 by stalling axonal vesicular transport. Moreover, axon-specific deletion of ngr1 preserves axonal transport mechanisms, blunting the induction of inflammatory demyelination and limiting the severity of EAE.SIGNIFICANCE STATEMENT Multiple sclerosis (MS) is commonly induced by aberrant immune-mediated destruction of the protective sheath of nerve fibers (known as myelin). However, it has been shown that MS lesions do not only consist of this disease pattern, exhibiting heterogeneity with continual destruction of axons. Here we investigate how neuronal NgR1 can drive inflammatory-mediated axonal degeneration and demyelination within the optic nerve by analyzing its downstream signaling events that govern axonal vesicular transport. We identify that abrogating the NgR1/pCRMP2 signaling cascade can maintain Kinesin-1-dependent anterograde axonal transport to limit inflammatory-mediated axonopathy and demyelination. The ability to differentiate between primary and secondary mechanisms of axonal degeneration may uncover therapeutic strategies to limit axonal damage and progressive MS.\n\nID: 30806815\nTitle: Retinal Neurodegeneration as an Early Manifestation of Diabetic Eye Disease and Potential Neuroprotective Therapies.\nAbstract: Diabetic retinopathy (DR) is a major cause of visual impairment and blindness throughout the world. Microvascular changes have long been regarded central to disease pathogenesis. In recent years, however, retinal neurodegeneration is increasingly being hypothesized to occur prior to the vascular changes classically associated with DR and contribute to disease pathogenesis. There is growing structural and functional evidence from human and animal studies that suggests retinal neurodegeneration to be an early component of DR. Identification of new therapeutic targets is an ongoing area of research with several different molecules undergoing testing in animal models for their neuroprotective properties and for possible use in humans. Retinal neurodegeneration may play a central role in DR pathogenesis. As new therapies are developed, it will be important to develop criteria for clinically defining retinal neurodegeneration. A standardization of the methods for monitoring neurodegeneration along with more sensitive means of detecting preclinical damage is also needed.\n\nID: 30690195\nTitle: Connexin43 hemichannels: A potential drug target for the treatment of diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR) is a chronic vascular disease of the retina that causes vision loss in patients with type 1 and type 2 diabetes, and is associated with vascular dysfunction and occlusion, retinal oedema, haemorrhage and inadequate growth of new blood vessels. Current DR therapies primarily target downstream, later-stage vascular defects with a significant proportion of diabetic macular oedema patients being non-responders. Moreover, other evidence suggests that prolonged use of therapies targeting vascular endothelial growth factor (VEGF) might be associated with increased onset of geographic atrophy and retinal ganglion cell death. It is therefore highly desirable to prevent the onset of DR or arrest its progression at a stage preceding the appearance of more-advanced pathology by targeting upstream disease mechanisms. Connexin43 hemichannels play a part in the pathogenesis of chronic inflammatory diseases, including inflammasome pathway activation; and hemichannel block has been shown to alleviate vascular leak and inflammation. This review discusses the inflammatory changes occurring in DR as well as current therapies and their limitations. It then focuses on the role of connexin43 in DR, providing evidence for the utility of connexin43 hemichannel blockers as novel therapeutics for DR treatment.\n\nID: 30306321\nTitle: Metformin attenuates increase of synaptic number in the rat spinal dorsal horn with painful diabetic neuropathy induced by type 2 diabetes: a stereological study.\nAbstract: In our previous study, we have shown that number of synapses in the L5 segment of spinal dorsal horn increased significantly in a rat model of painful diabetic neuropathy (PDN) induced by high-dose of streptozotocin (an animal model of type 1 diabetes). The aims of this study were: (1) to determine whether high fat diet/low dose streptozotocin-diabetes, a rat model for type 2 diabetes, related PDN was also associated with this synaptic plasticity, (2) to reveal the range of this synaptic plasticity change occurred (in the whole length of spinal dorsal horn or only in the L5 lumbar segment of spinal dorsal horn) and (3) to discover whether treatment with metformin had effect on this synaptic plasticity. Male adult Sprague-Dawley rats were randomly allocated into the control group (n\u2009=\u20097), the PDN group (n\u2009=\u20096) and the PDN treated with metformin (PDN\u2009+\u2009M) group (n\u2009=\u20097), respectively. 28\u00a0days after medication, synaptic and neuronal numbers in the whole length of spinal dorsal horn or in 1\u00a0mm length of the L5 segment of spinal dorsal horn were estimated by the optical disector (a stereological technique). Compared to the control group and the PDN\u2009+\u2009M group, number of synapses in the L5 segment of spinal dorsal horn increased significantly in the PDN group (P\u2009<\u20090.05). There was no significant change between the control group and the PDN\u2009+\u2009M group in terms of the parameters in the L5 segment of the spinal dorsal horn (P\u2009>\u20090.05). Parameters of the whole length of spinal dorsal horn showed no significant changes (P\u2009>\u20090.05). Our results suggest that high fat diet/low dose streptozotocin diabetes related PDN is also associated with a numerical increase of synapses in the L5 segment of spinal dorsal horn but not in the whole length of spinal dorsal horn. Furthermore, the analgesic effect of metformin against PDN is related to its inhibition of numerical increase of synaptic number in the rat spinal dorsal horn.\n\nID: 30190527\nTitle: Different contributions of autophagy to retinal ganglion cell death in the diabetic and glaucomatous retinas.\nAbstract: Diabetes mellitus and glaucoma are the two major causes of selective retinal ganglion cell (RGC) death. To determine the relationship between autophagy and RGC death, we compared autophagy and the related molecular pathways in diabetic and glaucomatous retinas and examined their effect on RGC survival. Biochemical analysis of microtubule-associated protein light chain 3 (LC3)-II and beclin-1 were observed. To determine the pathways involved in autophagy induction, adenosine monophosphate-activated protein kinase (AMPK) and the mechanistic target of rapamycin (mTOR) were also explored. Beclin-1 and the LC3B-II to LC3B-I ratio significantly elevated at 4 and 8 weeks after glaucoma induction; however, only a slight increase was apparent in the diabetic retina. Significant upregulation of phosphorylated AMPK and downregulation of phosphorylated mTOR was evident in the diabetic retina. After autophagy was inhibited with 3-methyladenine (3-MA), apoptosis of RGCs was significantly increased in the diabetic retinas. However, 3-MA inhibition of autophagy decreased the apoptosis of RGCs in glaucomatous retinas. Therefore, our results suggest that RGC death is differentially regulated by autophagy and that the pathways involved differ depending on the triggering injury.\n\nID: 30016630\nTitle: Lack of Galectin-3 attenuates neuroinflammation and protects the retina and optic nerve of diabetic mice.\nAbstract: Diabetic retinopathy is the leading cause of acquired blindness in working-age individuals. Recent work has revealed that neurodegeneration occurs earlier than vascular insult and that distal optic nerve damage precedes retinal degeneration and vascular insult. Since we have shown that optic nerve degeneration is reduced after optic nerve crush in Galectin-3 knockout (Gal-3 -/-) mice, we decided to investigate whether Gal-3 -/- could relieve inflammation and preserve both neurons and the structure of the retina and optic nerve following 8\u202fweeks of diabetes. Diabetes was induced in 2-month-old male C57/bl6 WT or Gal-3 -/- mice by a single injection of streptozotocin (160\u202fmg/kg). Histomorphometric retinal analyses showed no gross difference, except for a reduced number of retinal ganglion cells in WT diabetic mice, correlated to increased apoptosis. In the optic nerve, Gal-3 -/- mice showed reduced neuroinflammation, suggested by the smaller number of Iba1+ cells, particularly the amoeboid profiles in the distal end. Furthermore, iNOS staining was reduced in the optic nerves of Gal-3 -/- mice, as well as GFAP in the distal segment of the optic nerve. Finally, optic nerve histomorphometric analyses revealed that the number of myelinated fibers was higher in the Gal-3 -/- mice and myelin was more rectilinear compared to WT diabetic mice. Therefore, the present study provided evidence that Gal-3 is a central target that stimulates neuroinflammation and impairs neurological outcomes in visual complications of diabetes. Our findings provide support for the clinical use of Gal-3 inhibitors against diabetic visual complications in the near future.\n\nID: 29565290\nTitle: Role of Inflammation in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy is a common complication of diabetes and remains the leading cause of blindness among the working-age population. For decades, diabetic retinopathy was considered only a microvascular complication, but the retinal microvasculature is intimately associated with and governed by neurons and glia, which are affected even prior to clinically detectable vascular lesions. While progress has been made to improve the vascular alterations, there is still no treatment to counteract the early neuro-glial perturbations in diabetic retinopathy. Diabetes is a complex metabolic disorder, characterized by chronic hyperglycemia along with dyslipidemia, hypoinsulinemia and hypertension. Increasing evidence points to inflammation as one key player in diabetes-associated retinal perturbations, however, the exact underlying molecular mechanisms are not yet fully understood. Interlinked molecular pathways, such as oxidative stress, formation of advanced glycation end-products and increased expression of vascular endothelial growth factor have received a lot of attention as they all contribute to the inflammatory response. In the current review, we focus on the involvement of inflammation in the pathophysiology of diabetic retinopathy with special emphasis on the functional relationships between glial cells and neurons. Finally, we summarize recent advances using novel targets to inhibit inflammation in diabetic retinopathy.\n\nID: 29452885\nTitle: Somatolactogens and diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR) is one of the most common of all diabetic complications. The number of people with DR in the United States is expected to increase to 16 million by 2050. DR is the leading cause of blindness among working-age adults in many different countries, including the United States. In later DR stages, neovascularization is associated with extensive retinal capillary non-perfusion and vitreo-proliferation leading to retinal detachment. This neovascularization is orchestrated by an imbalance of growth factors in the retina from which somatolactogens (pituitary growth hormone, GH-N; placental growth hormone, GH-V; prolactin, PRL; and placental lactogen, PL, also referred as chorionic somatomammotropin, CSH), may play an important role. Somatolactogens are a group of hormones that share many structural and functional features. They are important for physiological changes in pregnancy, for adequate development of the fetus, and in the case of GH-N, for promoting growth after birth. GH-N is synthesized by the anterior pituitary, GH-V and PL are secreted by the placenta, whereas, PRL is synthesized by the anterior pituitary and uterine decidua. However, in recent years the expression of GH-N and PRL and their receptors have been detected in other tissues including the retina, acting as neuroprotective and pro-angiogenic agents. The relationship of GH-N and diabetic retinopathy (DR) was established many years ago when it was observed that its deficiency was related to regression of DR while an increase in serum levels of GH-N, GH-V, and PL promoted DR. While more studies are needed to define the potential implications of GH-V and PL in DR pathogenesis, it has been demonstrated that GH-N and PRL participate in DR by enhancing neovascularization. Some PRL isoforms, however, have shown an anti-angiogenic activity rather than pro-angiogenesis and appears to be PRL's main role in the regulation of retinal vasculature. Somatolactogens are a group of hormones with a significant role in neuroprotection and angiogenesis regulation in the eye. Understanding the mechanisms of angiogenesis regulation by somatolactogens will potentially lead to the development of new drugs for DR.\n\nID: 42461929\nTitle: Long-Acting RXR Agonism Preserves Retinal Function and Modulates Inflammation in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss and is associated with reduced nuclear retinoid X receptor (RXR) activity. Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy.\n\nID: 42461351\nTitle: NREP is involved in xenon's protection against ischemic stroke injury through modulating microglial M1 polarization and neuroinflammation.\nAbstract: Ischemic stroke (IS) is associated with high mortality and disability rates, and secondary neuroinflammation is a key driver of exacerbated neuronal damage. Xenon (Xe) exhibits neuroprotective effects, yet the specific mechanism by which it regulates microglia remains unclear. Public transcriptome datasets of human stroke cortex (GSE56267) and Xe-treated microglia (GSE273575) were analyzed, and key genes were screened using machine learning. An oxygen-glucose deprivation/reoxygenation (OGD/R) model was established with human microglial cells (HMC3). NREP expression, microglial polarization, and inflammatory responses were assessed via Western blot, flow cytometry, and ELISA. HMC3 cells were co-cultured with human cortical neurons using Transwell inserts, and neuronal damage was evaluated by CCK-8 assay, kit-based detection, and flow cytometry. Finally, a middle cerebral artery occlusion (MCAO) model was established in rats to investigate the potential involvement of NREP in the neuroprotective effects of Xe in vivo. NREP was identified as a key regulatory gene that was downregulated after stroke and upregulated following Xe treatment. In the OGD/R model, Xe upregulated NREP expression in HMC3 cells, inhibited M1 polarization and proinflammatory cytokine release, and this effect could be partially reversed by NREP silencing. Xe-treated HMC3 cells mitigated apoptosis and oxidative stress in co-cultured neurons, which appeared to be, at least in part, dependent on NREP. In MCAO rats, Xe upregulated NREP in the brain and reduced infarct volume and neuroinflammation. Critically, in vivo knockdown of NREP significantly reversed these neuroprotective and anti-inflammatory effects of Xe. Xe treatment upregulated NREP expression, inhibited M1 polarization of microglia and neuroinflammation, and alleviated cerebral ischemia-reperfusion injury in experimental models. These findings suggest that NREP contributes to xenon-mediated neuroprotection and may serve as a potential therapeutic target, providing preliminary experimental evidence for subsequent translational research of IS.\n\nID: 42460327\nTitle: Neurovascular unit uncoupling in diabetic retinopathy: molecular mechanisms and stage-adapted therapeutic strategies.\nAbstract: Diabetic retinopathy (DR) is a major neurovascular complication of diabetes and remains a leading cause of vision loss among working-age adults worldwide. Although DR has traditionally been classified as a microvascular complication, it is now increasingly recognized as a neurovascular degenerative disorder involving coordinated injury to neuronal, glial, vascular, and extracellular matrix components of the retinal neurovascular unit (NVU). The NVU provides the structural and functional basis for coupling neuronal activity to local blood flow and for maintaining retinal immune and barrier homeostasis. In diabetes, chronic hyperglycemia, oxidative stress, inflammation, metabolic dysregulation, impaired vascular endothelial growth factor (VEGF)/angiopoietin-Tie (Ang/Tie) signaling, abnormal intercellular communication, and epigenetic memory progressively disrupt the coordinated interactions among NVU components, leading to neurovascular uncoupling. This concept helps explain why retinal functional abnormalities and neurodegenerative changes may precede clinically visible vascular lesions. In this review, we summarize cell-specific NVU alterations and the molecular mechanisms that drive neurovascular uncoupling in DR. We also discuss how this framework may support earlier diagnosis, mechanism-based phenotyping, and stage-adapted treatment strategies. Established therapies, including anti-vascular endothelial growth factor (anti-VEGF) agents, corticosteroids, and angiopoietin-2 (Ang-2)/Tie-2-directed vascular stabilization, are considered together with investigational approaches targeting oxidative stress, inflammation, neuroprotection, metabolic reprogramming, epigenetic regulation, and drug delivery. Reframing DR as a diabetes-driven disorder of early NVU uncoupling may help shift clinical thinking from late vascular rescue toward mechanism-based neurovascular protection, precision phenotyping, and stage-adapted intervention.\n\nID: 42457102\nTitle: Mitochondrial preservation underlies the antioxidant activity of nanoceria particles in light-induced retinal degeneration.\nAbstract: Age-related Macular Degeneration (AMD), the leading cause of blindness worldwide, is a multifactorial disease with mitochondrial dysfunction recognized as an early pathogenic event. In our preclinical studies, we demonstrated that a single Cerium-Oxide Nanoparticles (CeO2-NPs) intravitreal injection in a light-induced degeneration model, was able to counteract the retinal degeneration. Our aim was to investigate whether neuroprotection activity could be correlated with mitochondrial morpho-functional preservation. Bulk transcriptomic profiling of whole retinal tissue revealed that light-induced retinal injury was associated with suppression of mitochondrial-related gene networks, including components of the electron transport chain and regulators of mitochondrial dynamics, whereas CeO2-NPs treatment restored the expression of antioxidant and mitochondrial biogenesis-related genes. Ultrastructural analysis by electron microscopy showed preservation of Retinal Pigmented Epithelial mitochondria's morphology and by high-resolution crystallographic analysis confirmed the intracellular localization of CeO2-NPs in proximity to mitochondria. Furthermore, Western blot analysis demonstrated that CeO2-NPs maintained mitophagy markers at basal levels, preventing excessive activation of mitochondrial quality-control pathways. Together, these findings support mitochondrial preservation as a key mechanism underlying nanoceria-mediated retinal neuroprotection and highlight CeO2-NPs as promising candidates for maintaining retinal homeostasis in AMD.\n\nID: 42455433\nTitle: Plant-derived Natural Products in Neurological and Psychiatric Disorders: Mechanisms of Action and Synergistic Roles with Probiotics.\nAbstract: Plant-derived natural products have emerged as promising therapeutic agents for neurological and psychiatric disorders due to their diverse bioactive compounds and multi-target mechanisms of action. This review provides a mechanistic overview of medicinal plants and probiotics in modulating key pathological processes underlying disorders such as Alzheimer's disease, epilepsy, autism spectrum disorder, and major depressive disorder. A systematic literature search was conducted across PubMed, Scopus, and Web of Science databases to identify relevant studies examining the neuroprotective, metabolic, and anti-inflammatory effects of plant-derived compounds, probiotics, and SGLT2 inhibitors. The findings highlight shared mechanisms, including attenuation of oxidative stress, suppression of neuroinflammation, modulation of mitochondrial function, and regulation of the gut-brain axis. Bioactive compounds such as polyphenols, flavonoids, alkaloids, and terpenoids demonstrate significant potential in improving neuronal survival and synaptic plasticity. Probiotics further contribute through microbiota-mediated regulation of neurotransmitters and immune responses. SGLT2 inhibitors are discussed as a comparative pharmacological model exhibiting overlapping mechanisms. Collectively, these integrative approaches provide a mechanistic framework for understanding how plant-derived compounds, probiotics, and metabolically active pharmacological models may influence shared pathways involved in neurological and psychiatric disorders. However, most proposed neuroprotective and synergistic effects require further validation through standardized formulations, well-designed clinical trials, and careful safety assessment before they can be translated into routine clinical practice.\n\nID: 42455201\nTitle: Vitamin D Promotes Neuronal Survival via Nrf2 Upregulation in D-Galactose-Induced Mice: An In-Vivo and In-Silico Study.\nAbstract: Gradual loss of the homeostatic balance owing to deregulation of endogenous antioxidant defense pathways, such as nuclear factor erythroid 2-related factor 2 (Nrf2), contributes, at least in part, to the characteristic oxidative stress, neuronal loss, and cognitive decline associated with aging. Here, we adopted an integrated approach using behavioral, biochemical, histological, molecular, and in silico methods, exploring the neuroprotective efficacy of vitamin D against D-galactose-induced oxidative stress, neuroinflammation, and neurodegeneration. Chronic D-galactose administration (150\u00a0mg/kg, s.c) led to profound deficits in spatial learning, working memory, and recognition memory, besides increased oxidative stress, reduced antioxidant enzyme activity, suppression of Nrf2 and heme oxygenase-1 (HO-1) expression, and frank hippocampal neurodegeneration, as revealed by nissl staining. Vitamin D treatment (5\u00a0\u00b5g/kg i.p) significantly improved such deficits by restoring cognitive performance, reducing ROS and lipid peroxidation, enhancing endogenous antioxidant activities such as superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH) and glutathione peroxidase (GPx), and upregulating Nrf2 and HO-1 expression comparable to positive control, dimethyl fumarate (DMF). Co-administration of all-trans retinoic acid (ATRA), an antagonist for Nrf2, abrogated these protective effects, confirming the pathway specificity. Molecular docking studies have shown a strong binding affinity of Vitamin D to the regulatory domain of Nrf2, supporting a direct stabilizing interaction that may facilitate the activation of Nrf2. Nissl quantification has further demonstrated substantial preservation of neuronal integrity in hippocampal CA1, CA3, and DG regions following the treatment with vitamin D. Altogether, findings from this study show that vitamin D confers robust neuroprotection through Nrf2-dependent antioxidant mechanisms and mitigates aging-related neurodegeneration induced by D-galactose. The results highlighted vitamin D as a readily accessible therapeutic candidate for mitigating oxidative stress-driven cognitive decline.\n\nID: 42455114\nTitle: Comprehensive Evaluation of YJ-2 as a PAD4 Inhibitor in Alleviating Ischemic Brain Injury: From NETs-Induced Neurotoxicity to In\u00a0Vivo Neuroprotection.\nAbstract: To evaluate the neuroprotective potential of YJ-2, a novel peptidylarginine deiminase 4 (PAD4) inhibitor, against ischemia/reperfusion brain injury by targeting neutrophil extracellular trap (NET) formation. In vitro, a NETs-induced injury model was established using SH-SY5Y and bEnd.3 cells. YJ-2's effects on viability, apoptosis, oxidative stress, and barrier permeability were assessed via CCK-8, flow cytometry, and FITC-dextran assays. In\u00a0vivo, a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model received YJ-2 (10\u2009\u03bcmol/kg) intravenously. Outcomes included infarct volume (TTC staining), neurological score, neuronal apoptosis (TUNEL), and oxidative markers (ELISA). PAD4 activity and histone H3 citrullination (H3cit) were examined by western blot and immunofluorescence. YJ-2 reduced NET-mediated neuronal death and oxidative stress in\u00a0vitro, and improved endothelial barrier integrity. In MCAO/R rats, YJ-2 significantly lowered infarct volume (44.2%\u2009\u2192\u200930.6%), improved neurological function, and suppressed apoptosis. It also decreased PAD4 and H3cit expression in ischemic brain tissue, confirming target engagement. YJ-2, by preserving blood-brain barrier (BBB) integrity and reducing neuronal apoptosis, highlights its therapeutic potential for ischemic stroke.\n\nID: 42451691\nTitle: Indole-Derived Compounds as Redox-Modulators: Antioxidant Mechanisms in Neuronal Protection.\nAbstract: Neurodegenerative diseases, such as Alzheimer's, Parkinson's, and Amyotrophic lateral sclerosis, are distinguished by progressive neuronal dysfunction caused primarily by oxidative stress, mitochondrial impairment, neuroinflammation, and redox imbalance. Growing evidence suggests that indole-derived compounds have significant neuroprotective potential due to their antioxidant, anti-inflammatory, and redox-modulating properties. This review summarizes the structural and biological significance of indole scaffolds, focusing on the mechanisms by which natural, endogenous, microbiota-derived, and synthetic indole compounds protect neuronal networks. Indole-3-carbinol, 3,3'-diindolylmethane, indole-3-propionic acid, and melatonin are major indole derivatives that control important neuroprotective pathways like Nrf2/ARE signaling, mitochondrial bioenergetics, neurotrophic factor expression, apoptotic regulation, and suppression of proinflammatory mediators. These compounds also maintain synaptic plasticity, reduce reactive oxygen species production, and improve neuronal survival in neurodegenerative disease models. Additionally, updated information from translational and clinical research indicates that indole-based compounds may have promising therapeutic applications; however, obstacles like low bioavailability, metabolic instability, and blood-brain barrier penetration continue to be major obstacles to clinical application. Development in nanoparticle delivery systems, microbiome-targeted interventions, and rational structural optimization may improve therapeutic efficacy and translational potential. Overall, indole-derived compounds are a versatile class of redox modulators with potential applications in the prevention and treatment of neurodegenerative diseases via integrated antioxidant and neuroprotective mechanisms.\n\nID: 42451620\nTitle: Genistein Protects Against Lead-Induced Cognitive Impairment Through a Glutathione-Dependent Redox-Mitochondrial Apoptosis Axis.\nAbstract: Lead exposure remains a pervasive environmental and public health threat, imposing a substantial burden of neurodevelopmental and cognitive dysfunction, yet safe mechanism-oriented interventions remain limited. Genistein, a soybean-derived isoflavone with antioxidant and neuroprotective potential, may counter heavy metal-induced neural injury; however, whether its efficacy is associated with redox-metabolic remodeling is unclear. Here, we evaluated genistein in lead-exposed C57BL/6J mice and lead-challenged HT22 hippocampal neurons. Genistein improved novel-arm exploration and spatial memory without altering locomotor or swimming performance, and attenuated neuronal disorganization and apoptosis in hippocampal CA1, CA3 and dentate gyrus regions. These protective effects were accompanied by reduced blood and hippocampal lead accumulation, restored glutathione redox balance, enhanced antioxidant capacity, preserved mitochondrial integrity, and suppressed Bax/Caspase-3-associated apoptotic signaling. Importantly, because genistein also reduced hippocampal lead accumulation, the in vivo neuroprotection may reflect both reduced target-tissue lead burden and improved glutathione-related redox homeostasis. Untargeted metabolomics identified 59 genistein-responsive metabolites enriched mainly in glutathione metabolism, oxidative phosphorylation, and ascorbate/aldarate metabolism, linking metabolic remodeling to behavioral recovery and reduced oxidative-apoptotic injury. In HT22 cells, blockade of glutathione synthesis by buthionine sulfoximine markedly weakened genistein-mediated cytoprotection, mitochondrial membrane potential recovery, and apoptosis inhibition. Collectively, genistein mitigates lead-induced hippocampal neurotoxicity and cognitive impairment by restoring glutathione-centered redox-mitochondrial homeostasis, supporting its further development as a mechanistically defined dietary candidate for environmental pollutant-associated neural injury.\n\nID: 42451124\nTitle: Neuroprotective Effects of Sorghum Polyphenol in Alzheimer's Disease: In Vitro and In Silico Analyses.\nAbstract: Accumulation of amyloid-beta (A\u03b2) senile plaques in the human brain is a major hallmark of Alzheimer's disease (AD), which manifests as progressive decline in memory and cognitive functions and currently lacks effective disease-modifying therapies. Emerging evidence demonstrates that polyphenol-rich plant foods are potential complementary therapies for AD. In this study, we investigated crude polyphenol extracts (CPEs) and purified polyphenol extracts (PPEs) from three sorghum genotypes for their ability to inhibit A\u03b242-induced toxicity in MC-65 cells. Thioflavin T fluorescence, cell viability, mitochondrial function, oxidative stress assays, and Western blotting, along with RNA sequencing and computational analyses, were used to characterise both functional and transcriptomic responses of the cells to polyphenol treatments. CPEs and PPEs inhibited A\u03b242 aggregation by 67-76% and significantly reduced A\u03b2 oligomer species. The extracts increased cell viability against A\u03b2-induced toxicity by more than 70%, decreased intracellular oxidative stress, and enhanced mitochondrial activity by over 80%. Transcriptomic profiling revealed differential modulation of genes associated with ferroptosis and MAPK/NF- \u03baB signalling pathways, indicating regulation of inflammatory and oxidative-stress responses are mechanisms underlying the observed neuroprotection. This study demonstrates that polyphenol extracts from black and red sorghum genotypes exert strong multitarget neuroprotection against A\u03b242 toxicity in MC-65 cells. These findings support further evaluation of sorghum-derived polyphenols as complementary therapeutic candidates for AD, with in vivo studies required to establish efficacy and translational potential.\n\nID: 42451086\nTitle: Vitamin D Signaling in Neurodegenerative Disorders: Mechanisms, Therapeutic Potential, and Clinical Implications.\nAbstract: Vitamin D has long been recognized for its role in calcium homeostasis and bone metabolism; however, it is now emerging as an important regulator of central nervous system (CNS) function. Recent evidence suggests that vitamin D signaling contributes to the pathogenesis and progression of several neurodegenerative disorders. Vitamin D exerts neuroprotective effects through multiple mechanisms, including regulation of calcium homeostasis, modulation of immune responses, reduction in oxidative stress, stimulation of neurotrophic factors, and maintenance of blood-brain barrier (BBB) integrity. Vitamin D receptors and metabolizing enzymes are widely distributed across several brain regions, highlighting their direct involvement in neuronal function. This review summarizes the biosynthesis, metabolism, and signaling pathways of vitamin D. It explores its role in neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), stroke, and traumatic brain injury (TBI). Evidence from experimental and clinical studies indicates that vitamin D deficiency is associated with an increased risk and severity of these conditions, while supplementation may provide therapeutic benefits.\n\nID: 42451077\nTitle: Scutellaria baicalensis Extract Protects Against Cerebral Ischemia-Reperfusion Injury in Male Rats by Inhibiting Ferroptosis via the PI3K/AKT Pathway.\nAbstract: Background:Scutellaria baicalensis (Scu) extract has been traditionally used in the treatment of stroke-related syndromes, yet its underlying molecular mechanisms, particularly those involving ferroptosis, remain to be fully elucidated. Purpose: This study aims to validate the hypothesis that Scu extract improves cerebral ischemia-reperfusion injury (CIRI) by inhibiting ferroptosis through the PI3K/AKT signaling pathway. Methods: This study employed middle cerebral artery occlusion (MCAO) in male Sprague-Dawley (SD) rats and oxygen-glucose deprivation/reoxygenation (OGD/R) models to evaluate the protective effects of Scu extract against CIRI. Multiple approaches were integrated to elucidate the underlying mechanisms. Furthermore, a range of experimental techniques, including neurological function assessment, TTC staining, histopathological analysis, biochemical assays, qPCR, transmission electron microscopy (TEM), reactive oxygen species (ROS) detection, Western blotting, and immunofluorescence, were used to comprehensively validate its neuroprotective effects. Results: Scu extract significantly improved neurological outcomes and attenuated brain injury in MCAO rats. Proteomic analysis revealed significant enrichment of ferroptosis-related pathways, which was supported by reduced mitochondrial damage, decreased iron accumulation, and restoration of the SLC7A11/GPX4 axis. Subsequently, UPLC/Q-TOF-MS analysis revealed that four major bioactive components were absorbed in MCAO rats. KEGG pathway analysis based on network pharmacology further indicated that the PI3K/AKT signaling pathway is a key regulatory target. Notably, pharmacological inhibition of PI3K with LY294002 markedly abolished the anti-ferroptotic effects of Scu extract, which was further confirmed in vitro. Conclusions: This study demonstrates that Scu extract confers neuroprotection against CIRI in MCAO rats potentially through inhibiting ferroptosis via activation of the PI3K/AKT pathway.\n\nID: 42451075\nTitle: Maltol Protects Neuronal Cells by Alleviating Chronic Neuroinflammation, Pyroptosis, and Ferroptosis via HSP70 Upregulation in Microglia.\nAbstract: Objectives: Neuroinflammation is recognized as a significant characteristic of Alzheimer's disease (AD). Currently, there is a notable absence of effective pharmacological agents to prevent or treat neuroinflammatory processes associated with AD. Heat shock protein 70 (HSP70) is pivotal in the progression of neuroinflammation. In this study, we explored the potential of maltol, a Maillard reaction product derived from red ginseng, as a therapeutic agent for neuroinflammation. Methods: In vitro, HMC3 microglial cell models were developed to examine the regulatory effects of gradient concentrations of maltol (12.5, 25, 50 \u03bcM) on the TLR4/MyD88/NF-\u03baB p65 signaling pathway, neuroinflammation, and pyroptosis. Analyses of the GEO database and Gene Set Enrichment Analysis (GSEA) were performed to identify the core targets of maltol, followed by HSP70 gene silencing experiments to validate the targeted regulatory mechanism. Results: Maltol significantly mitigated LPS-induced neuronal damage and cognitive deficits in mice. It effectively suppressed microglia-mediated neuroinflammation and pyroptosis, reversed oxidative stress-induced neuronal ferroptosis, and inhibited neuronal apoptosis. In vitro experiments demonstrated that maltol obstructed TLR4/MyD88 binding, thereby inhibiting NF-\u03baB p65-mediated neuroinflammation and pyroptosis, while also alleviating excessive ROS accumulation to enhance oxidative stress and ferroptosis. Bioinformatics analysis identified HSP70 as a crucial target for the anti-inflammatory and antioxidant effects of maltol. Subsequent gene silencing experiments confirmed that maltol exerted its inhibitory effects on LPS-induced neuroinflammation and pyroptosis in an HSP70-dependent manner. Conclusions: Maltol exhibits significant protective effects against Alzheimer's disease-related neuroinflammation, oxidative stress, pyroptosis, and ferroptosis through the targeting of HSP70. This study elucidates the molecular mechanisms by which maltol improves neuroinflammatory injury and provides a novel theoretical foundation and therapeutic strategy for the intervention of Alzheimer's disease neuroinflammation using traditional Chinese medicine.\n\nID: 42450163\nTitle: Oleuropein Attenuates 6-Hydroxydopamine-Induced Cytotoxicity Through Redox Regulation in Differentiated Dopaminergic Neurons: Potential Involvement of RET-Associated Signalling.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by selective loss of dopamine-containing neurons (DCNs) in the substantia nigra. Oxidative stress and impaired neurotrophic signalling contribute to PD pathogenesis. Oleuropein (Ole), a phenolic compound found in olives and olive leaves, exhibits antioxidant and cytoprotective properties that may counteract neuronal injury. This study investigated the neuroprotective effects of Ole in differentiated dopaminergic neurons (dDCNs) derived from the human ReNcell VM model exposed to 6-hydroxydopamine (6-OHDA). Ole significantly attenuated 6-OHDA-induced cytotoxicity, restoring cell viability following post- and pre-treatment compared with toxin-treated cells. Tyrosine hydroxylase expression was preserved, indicating maintenance of the dopaminergic phenotype. Ole also reduced lipid peroxidation and restored total antioxidant capacity, supporting a role in redox homeostasis. Molecular docking suggested a stable interaction between Ole and the RET receptor tyrosine kinase, suggesting a potential involvement of RET-associated survival signalling pathways that requires further experimental validation. In addition, 6-OHDA altered extracellular vesicle (EV) release and EV-associated transcripts related to Wnt signalling (Wnt3a, Wnt5a, GSK3), while Ole partially restored EV release profiles and EV-associated Wnt signalling-related transcripts. Collectively, these findings indicate that Ole protects dDCNs from oxidative stress and highlight its potential as a neuroprotective agent against dopaminergic neuronal injury.\n\nID: 42449057\nTitle: Ficus deltoidea Preserves Hippocampal Neuronal Integrity and Redox Balance in Oxidative Stress-Driven Alzheimer's Disease-Like Rat Model.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the leading cause of dementia worldwide, with oxidative stress playing a central role in its pathogenesis. Ficus deltoidea (FD), a medicinal plant rich in flavonoids vitexin and isovitexin, possesses potent antioxidant and anti-inflammatory properties, yet its neuroprotective efficacy in AD remains incompletely characterized. This study investigated the protective effects of FD in a D-galactose- and aluminum chloride (AlCl3)-induced oxidative stress-driven AD-like rat model using behavioral, histological, ultrastructural, and biochemical approaches. Fifty-four male Wistar rats were assigned to six groups: control, AD-like model, donepezil (1\u00a0mg/kg), and FD-treated groups (50, 100, and 200\u00a0mg/kg) for 10\u00a0weeks. Anxiety-like behavior and spatial working memory were assessed using the elevated plus maze (EPM) and T-maze tests, respectively. Hippocampal neuronal integrity was evaluated by hematoxylin and eosin (H&E) staining and transmission electron microscopy (TEM), while oxidative stress biomarkers (MDA, CAT, T-SOD, CuZn-SOD, and HO-1) were quantified using ELISA. FD treatment, particularly at 200\u00a0mg/kg, significantly improved spatial working memory and normalized anxiety-related behavior, with treatment responses approaching those observed in the donepezil-treated group. Histological analyses revealed preservation of pyramidal neurons across CA1, CA2, CA3, and dentate gyrus subregions, while ultrastructural studies demonstrated marked protection of mitochondrial integrity, myelin sheath organization, and smooth endoplasmic reticulum morphology. Biochemically, FD significantly reduced lipid peroxidation and enhanced endogenous antioxidant defenses. In conclusion, FD exerted significant neuroprotective effects characterized by preservation of hippocampal structure, maintenance of neuronal ultrastructure, and restoration of redox homeostasis in an oxidative stress-driven AD-like model. These findings demonstrate that FD mitigates oxidative stress-associated neuronal injury and cognitive impairment in a D-galactose and AlCl3-induced AD-like rat model, supporting its potential as a phytotherapeutic candidate for oxidative stress-related neurodegeneration. However, further studies are required to determine its effects on canonical Alzheimer's disease pathologies, including amyloid and tau abnormalities.\n\nID: 42449035\nTitle: Neuroprotective Effect of Delicaflavone in Rotenone-induced Parkinson's Disease in Rats: Role of Nrf2/HO-1, NF-\u03baB and PI3K/Akt/mTOR Pathways.\nAbstract: Parkinson's disease is a progressive neurodegenerative disease characterized by degeneration of dopaminergic neurons in the substantia nigra, reduced striatal dopamine levels, mitochondrial dysfunction, oxidative stress, and neuroinflammation. Delicaflavone, a natural biflavonoid, possesses antioxidant, anti-inflammatory, and neuroprotective effects; however, its neuroprotective potential against rotenone-induced Parkinson's disease warrants exploration. To induce Parkinson's disease in rats, 0.5\u00a0mg/kg of rotenone was administered subcutaneously for 28\u00a0days, and delicaflavone was administered orally at different doses (10, 20, and 40\u00a0mg/kg). In addition to behavioral tests, neurochemical parameters, oxidative stress, mitochondrial function, inflammatory cytokines, and apoptosis were assessed. Delicaflavone treatment increased square-crossed activity and rotarod performance and reduced catalepsy time. It was also found to positively affect neurochemical parameters, activate antioxidant enzymes, and support neuronal survival by inhibiting apoptosis. In addition to suppressing inflammatory parameters, it reduced pro-inflammatory cytokines and increased anti-inflammatory cytokines. Delicaflavone ameliorates rotenone-induced Parkinson's disease in rats via alteration of Nrf2/HO-1, NF-\u03baB mediated inflammatory pathway and PI3K/Akt/mTOR survival signaling pathway.\n\nID: 42447923\nTitle: Effect of nerolidol on seizure and oxidative brain damage induced by pentylenetetrazole in mice.\nAbstract: Nerolidol, a natural sesquiterpene alcohol found in essential oils, has demonstrated antioxidant, anti-inflammatory, and neuroprotective properties. However, its effects on pentylenetetrazole (PTZ)-induced seizure and associated oxidative brain damage remain unclear. To evaluate the anticonvulsant effects of nerolidol on PTZ-induced seizures in mice and to investigate its impact on oxidative and nitrosative stress markers in the hippocampus and cortex. Male mice were divided into 5 groups: control, PTZ, and PTZ pretreated with nerolidol (25, 50, or 100\u2009mg/kg, orally) 30\u2009minutes before PTZ administration. Seizure activity was assessed by measuring latencies to minimal clonic seizures (MCSs) and generalized tonic-clonic seizures (GTCSs). After a behavioral evaluation, hippocampal and cortical tissues were analyzed for malondialdehyde (MDA), nitric oxide (NO) metabolites, superoxide dismutase (SOD), catalase (CT), and total thiol content. Nerolidol significantly increased MCS and GTCS latencies compared with the PTZ group. In the hippocampus, all doses reduced MDA levels, while in the cortex this effect was observed at 50 and 100\u2009mg/kg. Nitric oxide metabolites were decreased by the two higher doses in both brain regions. The PTZ-induced reductions in SOD and CT activities were reversed by nerolidol at all doses, and total thiol levels were restored at 50 and 100\u2009mg/kg. Nerolidol exhibits anticonvulsant and neuroprotective effects on PTZ-induced seizures, likely mediated by reduced oxidative and nitrosative stress and enhancement of endogenous antioxidant defenses.\n\nID: 42447353\nTitle: Congenital stationary night blindness with a fundus albipunctatus-like yellow-dotted retina associated with compound heterozygous RPE65 variants: A case report.\nAbstract: This case describes congenital stationary night blindness (CSNB) with a fundus albipunctatus-like phenotype linked to compound heterozygous RPE65 variants, highlighting the diagnostic value of multimodal imaging and evidence-based variant interpretation. A retrospective case review including best-corrected visual acuity (BCVA), color vision testing, fundus photography, spectral-domain optical coherence tomography (SD-OCT), full-field electroretinography (ERG), and next-generation sequencing with parental segregation analysis. Variant pathogenicity was assessed using in-silico prediction models (PolyPhen-2 HumDiv and HumVar), and findings were integrated with clinical and imaging data. A sixteen-year-old male reported lifelong nyctalopia and stable difficulty seeing in dim. BCVA was 20/30 OD and 20/25 OS with normal color vision. Fundus examination revealed multiple white-yellow flecks along the arcades and mid-periphery with macular sparing. SD-OCT demonstrated preserved outer retinal architecture and an intact ellipsoid zone, and full-field ERG showed preserved rod and cone responses. Genetic testing identified two RPE65 missense variants: c.433G>A (p.Ala145Thr), likely pathogenic, and c.946A>G (p.Asn316Asp), reported as a VUS. PolyPhen-2 analysis classified p.Asn316Asp as damaging (HumDiv/HumVar score 1.000), and parental segregation demonstrated the variants in trans. Integration of genotype and phenotype supports p.Asn316Asp as likely pathogenic. Compound heterozygosity for hypomorphic RPE65 variants can produce a stationary fundus albipunctatus-like phenotype rather than progressive retinal degeneration. Careful integration of multimodal phenotyping and variant interpretation was essential for confirming disease causality.\n\nID: 42446255\nTitle: Methylene blue reduces the severity of lipopolysaccharide-induced morphological changes in microglia in rat cerebral cortex glial cell cultures.\nAbstract: Neuroinflammation is a process implicated in the development of many neurodegenerative diseases. It involves microglia, astrocytes, and cytokines. The aim of this study was to investigate the effects of neuroprotectors on morphology of microglial cell during lipopolysaccharide (LPS)-induced neuroinflammation. Immunocytochemical detection of microglia using the IBA1 marker in glial cell cultures obtained from rat cerebral cortex revealed the presence of a significant number of microglial cells in the studied culture. In the control, microglial cells possessed a large number of processes typical of nonactivated cells. In cultures treated with LPS (10 \u03bcg/ml, 24 h), microglia had a flattened amoeboid morphology, characteristic of activated cells. Furthermore, LPS treatment also resulted in an increase in the profile field area of the cell body, while the perimeter did not increase significantly, indicating a more rounded cell body shape compared to the control. In cultures treated with methylene blue (1 \u03bcM, 24 h) in the presence of LPS, microglial cells had a larger number of processes and a smaller body profile area than microglia treated with LPS alone, and their perimeter did not differ significantly from that of control cells. In the case of menadione (1 \u03bcM, 24 h) in the presence of LPS, the cells retained an amoeboid shape, and their size did not change significantly compared to the LPS group. Microglia treated with methylene blue alone did not differ from control microglia in morphology, body profile area, or perimeter, whereas menadione caused a significant increase in the cell's body profile area and a shift in their morphology toward an activated phenotype. Methylene blue, a substance whose anti-inflammatory action is associated with Nrf2 activation, is capable of not only reducing the production of proinflammatory cytokines but also preventing the transition of microglia to the activated phenotype.\n\nID: 42445281\nTitle: Advances in research on pharmacological mechanisms of anatabine: from nicotinic modulation to multitarget therapeutic potential.\nAbstract: Anatabine, a characteristic minor alkaloid derived from tobacco byproducts, exhibits unique structural analogy to nicotine but possesses a superior safety profile and lower addictive liability, rendering it a promising natural multi-target therapeutic candidate. Accumulating preclinical evidence has demonstrated that anatabine exerts neuroprotective, anti-inflammatory, and antioxidant effects mainly through modulating \u03b17/\u03b14\u03b22 nicotinic acetylcholine receptors, suppressing NF-\u03baB/STAT3 inflammatory signaling, and activating the Nrf2-mediated antioxidant pathway. It effectively ameliorates typical pathological alterations, including \u03b2-amyloid deposition, tau hyperphosphorylation, and microglial overactivation, thereby improving cognitive and behavioral deficits in neurodegenerative disease models. Additionally, anatabine displays broad pharmacological potentials in chronic inflammation, autoimmune thyroiditis, asthma, and hypertension. Differing from previous reviews that merely focused on single receptor regulation, the present work systematically summarizes the multi-target pharmacological characteristics of anatabine, comprehensively collates its preclinical efficacy across multiple disease categories, and highlights its advantages over nicotine in safety and addiction risk. Furthermore, we analyze the current limitations, druggability optimization challenges, and clinical translation prospects, and propose sustainable strategies for high-value utilization of tobacco byproducts. This review provides an updated and systematic theoretical basis for further mechanism exploration and therapeutic development of anatabine.\n\nID: 42445254\nTitle: Current and emerging drugs for Parkinson's disease: mechanisms, clinical evidence, and future directions.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by dopaminergic neuronal loss and \u03b1-synuclein pathology, resulting in disabling motor and non-motor symptoms. Pharmacotherapy remains the cornerstone of PD management, yet current treatments are largely symptomatic and fail to halt disease progression. In recent years, substantial advances have been made in both dopaminergic and non-dopaminergic therapeutic strategies. Novel formulations of levodopa and dopamine agonists aim to provide more stable dopaminergic stimulation and reduce motor fluctuations. Meanwhile, emerging non-dopaminergic agents targeting glutamatergic, serotonergic, adenosinergic, and cholinergic systems offer new options for managing dyskinesia, gait impairment, and neuropsychiatric symptoms. Importantly, growing efforts are directed toward disease-modifying therapies, including \u03b1-synuclein immunotherapy, inhibitors of protein misfolding and aggregation, glucocerebrosidase-targeted interventions, and neuroprotective agents that modulate mitochondrial dysfunction, oxidative stress, inflammation, and metabolic signaling. Although many candidates have shown encouraging preclinical or early clinical results, definitive disease-modifying efficacy remains to be established. This review summarizes recent progress in PD pharmacotherapy, highlights translational challenges, and discusses future directions toward precision medicine and combination strategies for achieving sustained symptomatic control and disease modification.\n\nID: 42445191\nTitle: Protective effect and mechanisms of Buyang Huanwu decoction against hypobaric hypoxia-induced brain injury in mice: involvement of inflammatory responses and HIF-1/PI3K-Akt-related pathways.\nAbstract: This study aimed to investigate the preventive and protective effect of Buyang Huanwu Decoction (BHD) against hypobaric hypoxia-induced brain injury in mice and to explore its underlying mechanisms. Particular emphasis was placed on evaluating whether BHD pretreatment could prevent or attenuate hypobaric hypoxia-induced neurological dysfunction and hippocampal injury, and on clarifying its potential mechanisms from the perspectives of inflammatory responses, metabolic regulation, and HIF-1/PI3K-Akt-related pathways. A mouse model of hypobaric hypoxia-induced brain injury was established by exposure to a simulated high-altitude hypoxic environment equivalent to an altitude of 6000\u00a0m for 72\u00a0h. Mice were assigned to the normal control, model, BHD-pretreated, and acetazolamide-positive control groups. BHD and acetazolamide were administered once daily by intragastric gavage, starting 4 days before hypobaric hypoxia exposure and continuing during the 72\u00a0h exposure period. Open field testing was performed to assess spontaneous locomotor activity and exploratory behavior. Hippocampal injury was evaluated by hematoxylin and eosin staining, Nissl staining, and HIF-1\u03b1 immunofluorescence staining. Non-targeted serum metabolomics, network pharmacology, hippocampal transcriptomics, and RT-qPCR validation were integrated to explore the potential mechanisms of BHD pretreatment. BHD pretreatment prevented hypobaric hypoxia-induced behavioral abnormalities and alleviated hippocampal pathological injury, neuronal loss, and Nissl body reduction. BHD also reduced excessive hippocampal HIF-1\u03b1 expression. Multi-omics analyses suggested that the protective effect of BHD was associated with the regulation of inflammatory responses, metabolic disturbances, and HIF-1/PI3K-Akt-related signaling. RT-qPCR validation showed that BHD modulated the abnormal expression of HIF-1\u03b1, IL-6, VEGFA, NF-\u03baB1, and STX1A in hippocampal tissue. BHD exerts a preventive neuroprotective effect against hypobaric hypoxia-induced brain injury in mice. Its effects may involve coordinated regulation of hypoxic responses, inflammatory signaling, metabolic remodeling, and HIF-1/PI3K-Akt-related pathways.\n\nID: 42444799\nTitle: Advances in the prevention and treatment of radiation-induced brain necrosis: a narrative review.\nAbstract: Radiation-induced brain necrosis (RBN) is a serious and often debilitating complication of radiotherapy for intracranial and head and neck malignancies, with an incidence of 5-25%. It can lead to significant cognitive impairment, neurological deficits, and increased mortality. As radiotherapy techniques advance and patient survival improves, effective prevention and management of RBN have become critical clinical priorities. This review systematically summarizes the current understanding of RBN pathogenesis, highlighting the central roles of vascular injury (endothelial damage, HIF-1\u03b1/VEGF dysregulation) and neuroinflammation (microglial activation, cytokine release). We discuss recent advances in preventive strategies, including refined radiotherapy modalities such as intensity-modulated radiotherapy (IMRT), fractionated stereotactic radiosurgery (fSRS), and FLASH ultra-high-dose-rate radiotherapy, as well as pharmacological prophylaxis using bevacizumab and neuroprotective agents (NGF, GM1, edaravone). Established and emerging treatment options are reviewed, including corticosteroids, bevacizumab, hyperbaric oxygen therapy (HBOT), laser interstitial thermal therapy (LITT), and Colony Stimulating Factor 1 Receptor(CSF1R) inhibitors. We also cover innovations in imaging for early detection and differential diagnosis, including magnetic resonance spectroscopy (MRS), perfusion-weighted imaging (PWI), and Positron Emission Tomography-Computed Tomography(PET/CT) with advanced tracers (11C-methionine, 18F-FET). Finally, we summarize updates to international management guidelines, particularly the 2022 DEGRO guidelines, and propose future directions for research and therapeutic optimization.\n\nID: 42443612\nTitle: Grape Seed Proanthocyanidin Extract (GSPE) Mitigates Preterm White Matter Injury in Mice Via Improving Mitochondrial Homeostasis and Activity of IMMP2L-Related Signaling Pathway.\nAbstract: Grape seed proanthocyanidins extract (GSPE) has demonstrated significant neuroprotective efficacy in various neurodevelopmental disorders, nevertheless its potential beneficial role in preterm white matter injury (PWMI) remains unclear. This study aims to evaluate the therapeutic potential of GSPE against PWMI and the underlying mechanisms. GSPE (20\u00a0mg/Kg) was taken orally by the mouse after PWMI modeling. The survival rate, incidence of macroscopic lesions, body weight change were calculated. The myelin damage was evaluated. Mitochondrial homeostasis\u200c was detected in PWMI model mice and cultured oligodendrocyte precursor cells (OPCs). Brain tissues from mice groups underwent RNA-seq.\u00a0A dual-luciferase reporter assay was employed to validate the direct binding interaction between miR-153 and IMMP2L mRNA. The results showed that treatment of GSPE ameliorated cerebral ischemic injury in PWMI mice and improved behaviour ability and cognition deficits. GSPE restored mitochondria homeostasis in both PWMI mice and OPCs. Additionally, IMMP2L was found to be increased, while ROS was diminished by GSPE intervention. KEGG analysis showed that Wnt signaling pathway, the downstream of IMMP2L, changed significantly in PWMI group, while GSPE reversed it. The dual-luciferase reporter assay demonstrated that miR-153-3p directly suppressed IMMP2L expression through these binding sites. In summary, our findings revealed that GSPE treatment alleviated PWMI and restored mitochondrial homeostasis in mice.These beneficial effects are likely be attributed to the improvement of the activity of IMMP2L-related signaling pathways by GSPE.\n\nID: 42443448\nTitle: Elamipretide (SS-31) and Nicotinamide Mononucleotide (NMN) Combination Therapy Targets TREM2 to Mitigate Post-ischemic Brain Injury in Mice.\nAbstract: Ischemic stroke is a severe cerebrovascular disorder characterized by a cascade of pathological processes, including neuroinflammation and apoptosis. These processes lead to high mortality rates and long-term disabilities, imposing substantial socioeconomic burdens. Although reperfusion therapies have improved patient outcomes, many remain ineligible due to narrow therapeutic windows or clinical contraindications. Consequently, developing novel neuroprotective strategies is of significant clinical importance. Elamipretide (SS-31) and nicotinamide mononucleotide (NMN) are well-documented neuroprotective agents operating through distinct mechanisms; however, their combined efficacy and underlying mechanisms in ischemic stroke remain elusive. This study investigated the neuroprotective efficacy of SS-31 and NMN, alone or in combination, in a mouse model of ischemic stroke, with a specific focus on their modulation of triggering receptor expressed on myeloid cells 2 (TREM2)-mediated neuroinflammatory and apoptotic pathways. A middle cerebral artery occlusion/reperfusion (MCAO/R) model was established in male mice, followed by treatment with SS-31, NMN, or their combination. Therapeutic outcomes were evaluated using neurobehavioral scoring, histopathological staining, transcriptomic sequencing, and protein expression analyses. TREM2 overexpression experiments and specific pharmacological inhibition of the NF-\u03baB pathway were conducted to elucidate the specific molecular mechanisms. Co-administration of SS-31 and NMN significantly attenuated post-ischemic brain damage and ameliorated neurological deficits (P\u2009<\u20090.0001), demonstrating effects markedly superior to either monotherapy. Transcriptomic profiling revealed that the combination therapy specifically modulated innate immune and apoptotic pathways, concomitant with a significant downregulation of TREM2. Mechanistically, the combination therapy effectively inhibited NF-\u03baB (p65) activation, thereby downregulating TREM2 expression. This suppression attenuated microglial activation, reduced the expression of canonical pro-inflammatory cytokines (IL-1\u03b2, TNF-\u03b1, and IL-6), and rebalanced the Bcl-2/Bax apoptotic axis. Overexpression of TREM2 entirely reversed these neuroprotective benefits. Combination therapy with SS-31 and NMN provides robust neuroprotection against ischemic stroke by suppressing the NF-\u03baB/TREM2 signaling axis, thereby combinatorially modulating post-stroke neuroinflammation and apoptosis. These findings highlight a novel, multi-targeted strategy for precision stroke interventions.\n\nID: 42443245\nTitle: High-performance liquid chromatography - diode array detection method validation for amentoflavone-type biflavonoids in five Encephalartos species with potential neuroprotective activity.\nAbstract: Ginkgo biloba is a well-known food supplement for enhancing memory and is rich in biflavonoids. Biflavonoids are predominant in the Order Cycadales (cycads). Among cycads, five Encephalartos species, E. ferox, E. kisambo, E. laurentianus, E. natalensis, and E. villosus, were selected to assess the neuroprotective potential by estimation of the antioxidant and acetylcholinesterase (AChE) inhibition activities. E. natalensis and E. ferox strongly inhibited AChE (IC50=1.349\u2009\u00b1\u20090.041 and 1.948\u2009\u00b1\u20090.06\u00a0\u00b5g/mL respectively), while E. kisambo and E. ferox were the most potent antioxidant. Accordingly, E. ferox was selected for further investigation. Chromatographic isolation of the ethyl acetate fraction afforded amentoflavone (1), bilobetin (2), ginkgetin (3), naringenin (6), and apigenin(7). The isolated biflavonoids (1-3) showed potent AChE inhibitory activity with IC50= 2.146\u2009\u00b1\u20090.086, 0.762\u2009\u00b1\u20090.039, and 1.474\u2009\u00b1\u20090.061\u00a0\u00b5g/mL respectively compared to rivastigmine, the positive control (IC50= 3.357\u2009\u00b1\u20090.103\u00a0\u00b5g/mL). A validated high-performance liquid chromatography with diode array detection (HPLC-DAD) method was developed for the simultaneous estimation of five biflavonoids: amentoflavone, bilobetin, ginkgetin, isoginkgetin and sciadopitysin in the five Encephalartos species and Ginkgo biloba. In addition, total phenolic and total flavonoid contents were estimated in the selected plants. This study highlights Encephalartos as a potential source of bioactive compounds for further neuroactive drug discovery research.\n\nID: 42442915\nTitle: Activation of Nrf2 neuroprotective pathways for treatment of Parkinson's disease: A state of art review.\nAbstract: The regulation of Nuclear Factor-Erythroid 2 Like 2 (NRF2) signaling has been shown to be a promising strategy to modulate the progression of the neurodegeneration associated to Parkinson's Disease (PD). Aim of this review is to update the knowledge of Nrf2 as neuroprotective agent of PD. Activation of Nrf2, a transcription factor that regulates the expression of antioxidant and cytoprotective genes, has emerged as a promising therapeutic strategy for PD. Nrf2 is a master regulator of the cellular antioxidant response and is responsible for activating the expression of genes that encode antioxidant enzymes such as superoxidedismutase, catalase, and glutathione peroxidase. Pharmacological agents such as sulforaphane, curcumin, and resveratrol have been shown to activate Nrf2 and upregulate the expression of antioxidant genes in preclinical PD models. Clinical trials are currently underway to evaluate the efficacy of these pharmacological agents in patients with PD. While the neuroprotective role of Nrf2 in PD holds great promise for the development of novel therapies, there are several challenges and limitations that need to be addressed in order to harness the full potential of this pathway in the clinic. Overcoming these obstacles will require interdisciplinary collaborations, innovative research approaches, and a greater understanding of the complex pathophysiology of PD. By addressing these challenges, we can move closer to developing effective neuroprotective therapies that can slow or stop the progression of PD and improve the quality of life for patients with this devastating disease.\n\nID: 42442677\nTitle: Saebias A-G, eudesmane sesquiterpenes from Salvia plebeia with potential for Alzheimer's disease prevention via anti-neuroinflammatory and neuroprotective effects.\nAbstract: Saebias A-G (1-7), seven previously undescribed eudesmane sesquiterpenoids compounds and seventeen known compounds were isolated from Salvia plebeia R.Br. Among them, compound 1 is a unique C16-type eudesmane sesquiterpenoid featuring a 6/6/5-membered scaffold, 2-3 are nor-eudesmane sesquiterpenoids and 5 contains a rare 6/6/3/5 tetracyclic skeleton. Their structures including absolute configurations were elucidated by extensive spectroscopic methods, single-crystal X-ray crystallographic and ECD calculation. All compounds were evaluated for their inhibitory effect on nitric oxide (NO) production induced by lipopolysaccharide (LPS) in BV-2 cells and neuroprotective effect induced by H2O2 in PC12 cells. The results showed that four compounds exhibited significant NO inhibitory effects, with IC50 values ranging from 0.76 to 3.72 \u03bcM. Among them, compound 2 showed significant inhibitory effect, which significantly suppressed the production of IL-6, IL-1\u03b2, and iNOS in a concentration-dependent manner. The PC12 cells damage induced by H2O2 was attenuated by compounds 2, 10, 11, 13, 15, and 23. Moreover, compounds 2 and 11 delayed H2O2 induced damage, stabilized reactive oxygen species (ROS), mitochondrial membrane potential (MMP) and apoptosis expression levels. Notably, compound 2 exerted dual anti-neuroinflammatory and neuroprotective activities, and its multi-target pharmacological profile makes it a promising candidate for the prevention and treatment of Alzheimer's disease. These studies provide new potential neuroprotective agents for the prevention and treatment of neurodegenerative diseases.\n\nID: 42440904\nTitle: Bruceine E, a natural quassinoid from Brucea javanica, inhibits PARthanatos via targeting PARP1 in ischemic stroke.\nAbstract: Ischemic stroke currently lacks evidence-based neuroprotective agents, primarily due to the challenge of timely intervention, which often occurs after the onset of irreversible neuronal damage. To address this, this study investigates the PARthanatos pathway, a form of regulated cell death triggered by DNA damage. Utilizing MNNG-induced cellular PARthanatos models, we screened a library of 2,939 traditional Chinese medicine monomers and identified Bruceine E, a natural product derived from Brucea javanica (bitterwood), as a potent inhibitor of PARthanatos at nanomolar concentrations, acting via the inhibition of PARP-1 overactivation. Bruceine E effectively prevents the accumulation of PAR-modified proteins, mitigates mitochondrial membrane potential collapse, and inhibits AIF nuclear translocation. Mechanistically, molecular docking, molecular dynamics simulations, surface plasmon resonance (SPR), and thermal stability assays demonstrate that Bruceine E interacts with the NAD + catalytic pocket of PARP-1 through six hydrogen bonds, exhibiting fast-binding and slow-dissociation kinetics. Furthermore, PARP1 overexpression rescue experiments confirmed that PARP1 overexpression markedly reversed the neuroprotective effect of Bruceine E, indicating that its pharmacological action is specifically dependent on PARP1 regulation. In a permanent distal middle cerebral artery occlusion (pdMCAO) model of C57BL/6 mice, a single intraperitoneal injection of 10\u00a0mg/kg Bruceine E administered 4.5\u00a0h after occlusion reduced infarct volume by approximately 80.2%, histological evidence confirmed that a single intraperitoneal administration of BE provided effective neuroprotection against ischemic brain injury.\n\nID: 42440180\nTitle: A Combination of Artemisinin, N-acetylcysteine, Resveratrol, and Hesperidin Ameliorates Hippocampal Damage and Pathological Features in an Experimental Model of Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive impairment and pathological accumulation of amyloid-\u03b2 and tau proteins. This study investigated the potential neuroprotective effects of a combined treatment consisting of artemisinin, N-acetylcysteine, resveratrol, and hesperidin in a streptozotocin (STZ)-induced intracerebroventricular (ICV) rat model of AD. Twenty 8-week-old rats were divided into four groups: control, SHAM, STZ-ICV, and STZ-ICV receiving oral administration of the compound combination for 30 days. Cognitive performance was evaluated using the Morris water maze and passive avoidance tests. Neurodegenerative and molecular changes were assessed through Western blot analysis of phosphorylated tau, amyloid-\u03b2-related markers, and apoptosis- and inflammation-associated proteins. Histological analyses included Nissl staining and immunofluorescence for amyloid deposition and caspase-3 expression. Results demonstrated that STZ-ICV administration induced significant cognitive impairment, neuronal loss, and increased amyloid-\u03b2 and phosphorylated tau levels. Treatment with the combined compounds partially improved behavioral performance and was associated with reductions in amyloid-\u03b2 deposition, tau phosphorylation, and caspase-3 expression, along with improved neuronal preservation in the hippocampus. These findings suggest that the combined administration of artemisinin, N-acetylcysteine, resveratrol, and hesperidin exerts multi-target neuroprotective effects in an experimental AD model, potentially through modulation of oxidative stress, neuroinflammation, and apoptotic pathways. However, further studies are required to evaluate pharmacokinetics, safety, and translational relevance before clinical application.\n\nID: 42438228\nTitle: Ameliorative Effects of a Naphthoquinone Derivative With \u03b2-Amyloid Aggregation Inhibitory Activity on Cognitive Impairment and Metabolite Analysis of the Blood and Brains of Mice.\nAbstract: Accumulation of amyloid-\u03b2 (A\u03b2) plaques is an important cause of Alzheimer's disease (AD) pathogenesis. In this study, we evaluated A\u03b2 aggregation inhibitory activity of synthesized naphthoquinone derivatives as well as improvement in cognitive functions and metabolite profiling of brain tissues using scopolamine (SCO)-induced mice. Compound 888 (2-(4-(2,3,4-trimethoxybenzyl)piperazin-1-yl)naphthalene-1,4-dione, [TPN]) showed the highest A\u03b2 aggregation inhibitory activity (IC50\u2009=\u20090.14\u2009\u03bcM), and was more potent than the reference compound curcumin (IC50\u2009=\u20091.63\u2009\u03bcM). Compound TPN showed effective monoamine oxidase (MAO)-A, MAO-B, acetylcholinesterase, and butyrylcholinesterase inhibitions at 10\u2009\u03bcM, likely as candidates for multitarget-directed ligands. TPN was permeable through the blood-brain barrier, and non-toxic to MDCK and SH-SY5Y cells. TPN displayed prolonged and stable interactions with A\u03b242 during molecular dynamics simulations, in contrast to the short-lived contacts observed for curcumin. Cognitive impairment was significantly improved by TPN-treatment in behavioral tests. TPN treatment attenuated A\u03b2-related protein expression, inflammatory responses, oxidative stress-related changes, and apoptosis-related alterations, while preserving hippocampal pyramidal neurons and their typical morphology. In metabolite profiling, TPN modulated a narrower set of pathways mainly related to amino acid and kynurenine metabolism, whereas donepezil induced broader adjustments involving amino acid, mitochondrial/energy, and lipid-related pathways compared to those in the serum and cortex of the SCO group, in contrast to those in the hippocampus. Collectively, a potent A\u03b2 aggregation inhibitor TPN showed significant cognitive improvement, accompanying by neuroprotective effects, decreasing inflammation, and retaining neuron structures, exhibiting changed metabolic profiles compared to the control treatments. These findings suggest that TPN has cognitive-protective and neuroprotective potential under scopolamine-induced impairment conditions and warrants further validation in AD-relevant models.\n\nID: 42438198\nTitle: The histone deacetylase inhibitor, suberoylanilide hydroxamic acid, restores blood-brain barrier integrity in a human stem cell-based model of ischaemic stroke.\nAbstract: Ischaemic stroke is characterised by acute cerebrovascular occlusion, blood-brain barrier (BBB) breakdown and a narrow therapeutic window for recovery. Its treatment is a clinical challenge due to the risk of reperfusion injury and the limited efficacy of thrombolytic therapies; therefore, novel therapeutic approaches are needed. Histone deacetylase inhibitors (HDACi) have emerged as neuroprotective agents in stroke models, but their effect on preserving BBB integrity is unexplored. Our aim was to investigate the effects of the HDACi, suberoylanilide hydroxamic acid (SAHA), on BBB changes in a cell culture model of ischaemic stroke. The effects of SAHA were tested on a human BBB co-culture model following a 6-h oxygen-glucose deprivation (OGD) under normoxia and during a 24 h reoxygenation (OGD/R). SAHA treatment ameliorated the OGD/R-induced loss of BBB integrity, as shown by an increase in transendothelial electrical resistance and reduced BBB permeability. The expression of genes involved in cell proliferation decreased, whereas an increase was measured for basement membrane protein, glycocalyx-synthesis enzyme and Wnt signalling-related genes. SAHA treatment elevated the claudin-5 protein expression and a metabolic shift from glycolysis to aerobic respiration was observed. Our results suggest that SAHA could be a potential adjunctive therapeutic drug for the treatment of ischaemia-reperfusion injury via BBB protection. Because SAHA has already been approved for human use as the anticancer drug vorinostat, its repurposing to restore BBB functions and prevent poststroke damages may be greatly facilitated.\n\nID: 42438182\nTitle: Neuroprotective Effects of 3,6-Dihydroxyflavone in LPS-Stimulated BV-2 Microglial Cells and an MPTP-Induced Mouse Model of Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a leading neurodegenerative disorder and is triggered by genetic mutations, environmental toxins, and aging, with limited available treatments. 3, 6-dihydroxyflavone is a flavonoid with antioxidant, anti-apoptotic, and neuroprotective properties. However, the neuroprotective effect of 3,6-DHF on MPTP-induced oxidative stress and neuroinflammation in a PD mouse model has not yet been investigated. In this study, we investigated whether 3,6-dihydroxyphenylhydrazine (3,6-DHF) is protective against MPTP-induced oxidative stress and neuroinflammation and explored its potential neuroprotective mechanism. 3,6-DHF was administered orally at doses of 5, 10, and 20\u2009mg/kg/day for 7 days. MPTP was administered at 30\u2009mg/kg/day via intraperitoneal injection, once daily, for 4 consecutive days, from day 4 to day 7. In vitro, 3,6-DHF enhanced cell survival and suppressed inflammatory markers and NF-\u03baB/MAPK signaling pathways associated with microglial activation in LPS-stimulated BV-2 cells. In the in vivo study, 3,6-DHF reduced PD motor deficits and enhanced motor performance in the open field test, beam walking, rotarod, pole, and grip strength tests. 3,6-DHF significantly reduced neuronal oxidative stress by decreasing lipid peroxidation, which in turn helped restore impaired antioxidant enzyme activity, while also enhancing the expression of Nrf2 and HO-1 proteins. It also increased the expression levels of the TH protein, reduced the expression of inflammatory mediators, and inhibited the activation of microglia and astrocytes induced by MPTP. These results suggest that 3,6-DHF effectively modulates neuroprotective, antioxidant, and neuroinflammatory processes and improves motor functions, highlighting its potential for further exploration in PD treatment.\n\nID: 42436855\nTitle: Gene therapy induces synaptic ribbon maturation, synaptogenesis and vision recovery in an adult dog model of retinal degeneration.\nAbstract: The extent to which regeneration is possible in adult mammalian synapses remains an intractable question in neuroscience. Calcium interactions at the first retinal synapse are necessary for normal retinal development and vision. Calcium binding protein 4 (CaBP4) modulates these interactions, and mutations in CaBP4 or the voltage-gated calcium channel lead to similar forms of visual impairment. We identified a spontaneous mutation in CaBP4 in dogs that results in synaptic loss of function, immaturity of synaptic ribbons, and disorganization and thinning of the outer plexiform layer (OPL). Adeno-associated virus (AAV)-mediated gene augmentation therapy restored synaptic function and vision and led to synaptic ribbon maturation and elongation. Therapy also resulted in retinal layer preservation and re-organization, including expansion of the previously thin adult OPL. We show that the restoration of calcium regulation is, therefore, requisite for retinal plasticity and remodeling. This first naturally occurring large-animal model of mutant CaBP4 recapitulates components of the human disease and illustrates the potency of gene therapy in reversing blindness caused by the loss of CaBP4, paving the way for a cure. Structural and molecular changes following gene therapy demonstrate the phenomenal plasticity of the OPL and its synaptic machinery, highlighting the potential of neuroplasticity in the mammalian central nervous system.\n\nID: 42436633\nTitle: Experimental study on the effects of dexmedetomidine via the mTOR signaling pathway on cognitive function in POCD rats after partial hepatectomy.\nAbstract: Postoperative cognitive dysfunction (POCD) frequently occurs after liver resection and is potentially mediated by the mTOR signaling pathway. Although dexmedetomidine, an \u03b12 receptor agonist, exhibits neuroprotective effects, it remains unknown whether it improves post-resection cognitive function by modulating the mTOR pathway. To discuss the influence of dexmedetomidine on the mTOR signaling pathway in the hippocampus of POCD rats after partial hepatectomy. Thirty Wistar rats were randomly divided into three equal groups: normal, model and treatment. The treatment group received dexmedetomidine, whereas the other two groups received saline. Histopathology, cognitive function and related gene/protein expression were compared among groups received saline. The treatment group showed improved hippocampal neuronal structure and arrangement compared to the model group, though still below normal levels; neural apoptosis was significantly reduced (P<0.05), and spatial learning and memory were enhanced; Akt expression was partially restored, while mTOR, NF-\u03baB and TNF-\u03b1 expression (protein/mRNA) remained higher than normal but significantly lower than in the model group (P<0.05). Dexmedetomidine ameliorates postoperative cognitive dysfunction in rats after liver resection by inhibiting the hippocampal mTOR pathway, reducing neuronal damage and inflammation.\n\nID: 42436556\nTitle: Pycnogenol attenuates thioacetamide-induced neurobehavioral impairment and hepatotoxicity via multi-target molecular modulation.\nAbstract: Hepatic encephalopathy (HE) is a neuropsychiatric syndrome associated with liver dysfunction and remains a major cause of mortality among patients with advanced liver disease. This study aimed to evaluate the protective effects of Pycnogenol in a rat model of thioacetamide-induced hepatic encephalopathy. Thirty-two rats were assigned to four groups: control, HE (TAA), and two treatment groups receiving Pycnogenol at 5\u00a0mg/kg and 10\u00a0mg/kg. HE was induced by intraperitoneal administration of TAA at 200\u00a0mg/kg for three consecutive days. Pycnogenol was administered orally for 14 days prior to and during TAA exposure. Behavioral tests (locomotor activity, elevated plus maze), histopathological evaluations, biochemical parameters, immunohistochemical staining, and gene expression analyses (qPCR) were performed. Pycnogenol administration resulted in significant improvements in locomotor activity, reductions in oxidative stress markers, and decreased expression of IL-1\u03b2, TNF-\u03b1, NF-\u03baB, and caspase-3. Histopathological examination revealed alleviation of hepatic and neuronal degeneration. Immunohistochemistry confirmed reduced GFAP and iNOS staining in brain tissues. Pycnogenol demonstrated neuroprotective and hepatoprotective effects in this experimental model, likely through modulation of oxidative stress and inflammatory pathways. Although these findings highlight the potential translational relevance of Pycnogenol as a supportive strategy for hepatic encephalopathy, further studies in chronic models and clinical settings are required to confirm its therapeutic applicability.\n\nID: 42435831\nTitle: Evaluation of the impact of gamma-aminobutyric acid on diabetic retinopathy in a large US population-based cohort.\nAbstract: To investigate how exposure to GABAergic medications affects diabetic retinopathy (DR) development, progression, and complications. Retrospective clinical cohort study using multi-institutional electronic health record data (TriNetX, US Collaborative Network) PARTICIPANTS: : Adults aged \u226518 years with type 2 diabetes mellitus with ophthalmology follow-up. Study cohorts had GABAergic prescription records for 6-months, 1-year, 3-years, or 5-years; control cohorts had no GABAergic prescriptions ever. Cohorts were propensity-score matched (PSM) on demographics, systemic comorbidities, common indications for GABAergic medications, and ophthalmic confounders. Outcomes included incident DR, progression from mild/moderate nonproliferative DR to severe nonproliferative DR, proliferative DR, or interventions required in advanced DR, and incident DR complications. Hazard ratio (HR) and 95% confidence intervals (CI); significance threshold <0.9 or >1.1. After successful PSM, there were 110,495 (6-months), 99,187 (1-year), 63,194 (3-years), and 40,810 (5-years) DR-naive study patients with the respective GABAergic prescription durations of interest. Compared to 109,603 DR-naive control patients, study patients demonstrated a significantly reduced HR for DR development at all time points from 6-months (HR 0.61, 95% CI 0.57-0.65) to 5-years (HR 0.81, 95% CI 0.77-0.85). Study patients (n=14,644) with baseline mild/moderate nonproliferative DR had a significantly reduced hazard of progressing to severe nonproliferative DR, proliferative DR, or DR interventions with 6-months (HR 0.75, 95% CI 0.68-0.82) and 1-year (HR 0.69, 95% CI 0.73, 0.86) GABAergic exposure. Prescription for 6-months (HR 0.74, 95% CI 0.68-0.80) to 3-years (HR 0.80, 95% CI 0.84-0.86) was associated with a significantly reduced hazard for DR complications. Stratification by 4 specific medication indications consistently showed a reduced hazard for DR development with a 6-month prescription duration. GABAergic medication use, particularly short-term exposure, is associated with a reduced hazard of DR development, progression, and complications. These exploratory findings support a potential role of GABAergic modulation in diabetic retinal disease.\n\nID: 42432263\nTitle: Repurposing apremilast for alzheimer's disease: multitarget modulation of cAMP\u2011PI3K/Akt-GSK\u20113\u03b2 and NF\u2011\u03baB signaling.\nAbstract: Alzheimer's disease (AD), the leading cause of dementia worldwide, represents a growing global health challenge driven by population aging, the absence of effective disease-modifying therapies, and its inherently multifactorial pathogenesis. This pathogenesis is characterized by amyloid-\u03b2 (A\u03b2) aggregation, tau hyperphosphorylation, persistent neuroinflammation, oxidative stress, and synaptic dysfunction. Conventional single-target interventions have consistently failed against this complex interplay of molecular events, thereby highlighting the need for multitarget, systems pharmacology approaches capable of simultaneously modulating convergent pathways. Apremilast (APR), an FDA-approved, orally bioavailable phosphodiesterase-4 (PDE4) inhibitor, has recently emerged as a favorable drug repurposing candidate capable of elevating intracellular cAMP and triggering a cascade of neuroprotective mechanisms. Preclinical investigations from A\u03b2-challenged neuronal cultures to high-fat diet/streptozotocin-induced rodent models of AD demonstrate that APR attenuates A\u03b2-induced cytotoxicity, improves cognitive performance, and preserves neuronal and synaptic integrity. Mechanistically, APR mitigates NF-\u03baB-mediated neuroinflammation through I\u03baB\u03b1 stabilization, thereby reducing the release of proinflammatory cytokines such as TNF-\u03b1 and IL-6; activates the Nrf2/HO-1 antioxidant defense pathway, and, via cAMP-dependent PI3K/Akt signaling, inhibits GSK-3\u03b2 to prevent tau hyperphosphorylation, synaptic loss, and neuronal degeneration. This review synthesizes current mechanistic evidence supporting apremilast as a potential multitarget repurposing candidate in AD, thereby addressing key knowledge gaps in the current literature. All supporting evidence was compiled from peer-reviewed sources indexed in PubMed, Web of Science, and Scopus. Guided by network pharmacology and systems biology frameworks, APR's polypharmacological profile positions it as a compelling multitarget candidate for advanced in vivo validation, human iPSC-derived neuronal studies, and AI-driven therapeutic discovery pipelines.\n\nID: 42431336\nTitle: Associationof Static and Dynamic Pupillary Abnormalities with Retinal Microvasculopathy and Neurodegeneration in Diabetics.\nAbstract: To investigate the characteristics of pupillary statics and dynamics and explore the relationship between pupillary abnormalities and microvascular as well as neurodegenerative changes of retina in the early stages of diabetes. This cross-sectional observational study included forty-eight diabetic subjects without diabetic retinopathy (NDR group), thirty-nine diabetic subjects with mild or moderate non proliferative diabetic retinopathy (DR group), and forty age- and sex-matched healthy adults (control group). Pupil size and pupillary light reflex were measured monocularly using a PLR-3000 dynamic pupillometer, and OCT/OCTA scans were acquired with a Van Gogh SS-OCTA device in all three groups. Both static and dynamic pupillary parameters differed significantly among the three groups (p <0.001). Pairwise comparisons showed that both basal and smallest pupil diameter were smaller in diabetes with or without retinopathy, compared to healthy control. Notably, pupillary dynamics didn't significantly reduce until retinopathy was present. Pupillary parameters showed a positive correlation with the thickness of the ganglion cell layer and inner plexiform layer in the parafovea, and the vessel density of the superficial vascular plexus and intermediate capillary plexus. Static pupillary abnormalities appear before clinical diabetic retinopathy. Both static and dynamic pupillary abnormalities worsen alongside retinal microvascular and neurodegenerative damages in the early stages of diabetes. Evaluation for autonomic nervous dysfunction is recommended for all patients with diabetic retinopathy.\n\nID: 42430127\nTitle: Oral Lysozyme Attenuates Neuroinflammation and Brain Injury After Traumatic Brain Injury Through Gut Microbiota-Dependent Reprogramming of Tryptophan Metabolism.\nAbstract: Traumatic brain injury (TBI) induces secondary neuroinflammation and gut dysbiosis. This study investigated whether oral lysozyme confers neuroprotection after TBI through gut microbiota-dependent metabolic reprogramming of tryptophan metabolism. In a severe TBI mouse model, neurological function, neuroinflammation, intestinal barrier integrity, and systemic immune homeostasis were assessed following oral lysozyme administration. Fecal untargeted metabolomics, antibiotic-mediated microbiota depletion, and fecal microbiota transplantation (FMT) were used to explore microbiota involvement. Cerebrospinal fluid (CSF) from 10 matched pairs of patients with severe TBI was analyzed for tryptophan pathway metabolites by liquid chromatography-mass spectrometry. Lysozyme improved neurological outcomes, attenuated neuronal apoptosis and neuroinflammation, and restored peripheral CD4+/CD8+ T cell homeostasis. Metabolomics revealed enrichment of fecal tryptophan metabolites (indole-3-carboxaldehyde, indolelactic acid, kynurenic acid [KYNA]) and a shift in cerebral kynurenine metabolism toward the KYNA branch. These associations were abolished by microbiota depletion and reproduced by FMT. Favorable clinical outcomes were associated with higher CSF KYNA and an elevated KYNA/QA ratio. Oral lysozyme was associated with attenuated TBI-induced neuroinflammation and brain injury, potentially through gut microbiota-dependent tryptophan metabolism reprogramming. Concordance between preclinical and clinical metabolomic data supports lysozyme as a candidate microbiota-targeted therapeutic strategy. The KYNA/QA ratio warrants further validation as a prognostic indicator in larger, longitudinal cohorts.\n\nID: 42428055\nTitle: NSAID use is associated with lower dementia and Alzheimer's disease prevalence and slower cognitive decline: A retrospective longitudinal analysis of the NACC cohort.\nAbstract: Dementia, particularly Alzheimer's disease (AD), is a major global health challenge, with prevalence projected to reach 150 million cases by 2050. AD is characterized by progressive cognitive decline linked to neuroinflammation and neurodegeneration. Non-steroidal anti-inflammatory drugs (NSAIDs) have been explored as potential neuroprotective agents, particularly diclofenac, which has been proposed to modulate microglial inflammasome signaling. However, prior studies investigating NSAIDs in AD have yielded inconsistent findings. We therefore reexamined the relationship between selected NSAIDs and dementia outcomes in a large longitudinal cohort from the National Alzheimer's Coordinating Center (NACC). We analyzed cross-sectional and longitudinal data from the NACC database collected between 2005 and 2022. Associations between NSAID exposure and dementia, AD, and cognitive trajectories were examined. Propensity score matching was performed to compare NSAID users with matched non-users while adjusting for demographic and clinical confounders. Longitudinal mixed-effects models were used to assess cognitive decline based on Montreal Cognitive Assessment (MoCA) scores. Among 47,165 participants, diclofenac and naproxen use were associated with a lower prevalence of dementia and AD compared with matched non-users, whereas etodolac showed no significant associations. Diclofenac users demonstrated reduced odds of dementia and AD. Naproxen showed similar cross-sectional associations. In longitudinal modeling, diclofenac users had a significantly slower rate of cognitive decline than non-users. These findings suggest a compound-specific association between NSAID use and AD, with diclofenac potentially modulating disease progression through anti-inflammatory mechanisms. The observed modulation of longitudinal cognitive decline supports further investigation of inflammatory pathways, including microglial and inflammasome signaling, as therapeutic targets in biomarker-defined AD populations.\n\nID: 42427758\nTitle: Exosomal Profiling Reveals Mechanisms of Hibernation-Associated Neuroprotection.\nAbstract: Glaucoma is a group of eye diseases that affects 4 million people in the US and is one of the leading causes of vision loss due to damage to the eye's optic nerve (ON) which is composed of axons from retinal ganglion cells (RGCs) that transmit visual information to the brain. Injury to the ON often triggers RGC death and subsequent loss of visual function. Despite its increasing prevalence worldwide, effective therapies for glaucoma remain elusive. Notably, the thirteen-lined ground squirrel (TLGS) exhibits intrinsic neuroprotection during hibernation; however, reproducing this protective state pharmacologically has proven challenging. To elucidate the metabolic mechanisms underlying this resilience, we conducted untargeted metabolomic analyses on TLGS retinas at 6 hours, 3 days, and 7 days following ON crush. Retinas from awake and hibernating animals were compared to identify temporal and state-dependent metabolic signatures. Distinct metabolomic profiles were observed in hibernating animals relative to their awake counterparts. Pathway analyses revealed coordinated regulation of amino acid, lipid, and purine metabolism that likely contributes to hibernation-induced resilience. Furthermore, our findings indicate that hibernating TLGS retinas increase exosome biogenesis, prompting in vitro validation using TLGS-derived exosomes, which demonstrated robust neuroprotective and anti-inflammatory effects. Proteomic and transcriptomic characterization of exosomal cargo identified conserved miRNAs, mRNAs, and proteins implicated in redox balance, cytoskeletal stabilization, and stress-response regulation. Collectively, these data support the hypothesis that metabolic reprogramming and exosome-mediated intercellular signaling underlie hibernation-associated neuroprotection. Modulating these pathways may provide a blueprint for novel therapeutic strategies to mitigate neurodegeneration and promote recovery following optic nerve injury.\n\nID: 42427680\nTitle: Therapeutic restoration of synaptic architecture, retinal and visual function, and prevention of retinal degeneration in a mouse model of retinal dystrophy.\nAbstract: Vision depends on the transfer of photoreceptor signals through the retina and then to many CNS visual nuclei. While the most common inherited retinal diseases (IRDs) involve defects in rod and/or cone function, another group (referred to as congenital stationary night blindness (CSNB)) results from defects in glutamate release from photoreceptors, or conversion of the glutamatergic signal in bipolar cells. One example results from mutations in the CACNA2D4 gene, which encodes a subunit of the voltage-gated calcium channel that is critical for glutamate release from both rod and cone photoreceptors. Mutations in CACNA2D4 result in a range of phenotypes in human patients, from incomplete CSNB to rod-cone dystrophy. In the CACNA2D4 knockout mouse ( \u03b12\u03b44 -/- ), there is slow photoreceptor degeneration, the photoreceptor-to-bipolar cell synapse is disorganized, and the retina lacks scotopic and photopic full-field electroretinogram b-waves; this also results in low visual acuity. Using adult \u03b12\u03b44 -/- mice, we show that recombinant adeno-associated virus (rAAV)-mediated gene therapy directed to rod photoreceptors prevents rod degeneration, restores synaptic organization, retinal function, and improves visual acuity under both light- and dark-adapted conditions. This rescue was maintained for up to 14 months post-treatment. Together, our results demonstrate that synaptic structure and function can be restored in the mature mouse retina in a model of complete synaptic disorganization. The results highlight the neuroprotective potential of targeting synaptic organizing proteins in retinal gene therapy.\n\nID: 42423809\nTitle: Polydatin inhibits hippocampal neurodegeneration in diabetic rats via modulation of oxidative stress and NF-kB/COX-2/IL-6 inflammatory pathway.\nAbstract: Impaired insulin function and persistent hyperglycemia damage the brain of diabetics and raise the risk of Alzheimer's disease (AD). Although polydatin (PLD) possesses promising biological effects, no major study has yet explored its anti-neurodegenerative efficacy in the hippocampus. This study therefore aims to investigate the probable protective effects of PLD against hippocampal neurodegeneration in diabetic rats, as well as explore its in-silico inhibitory activity against two key enzymes implicated in the progression of AD. Experimental diabetes was induced in male albino rats then PLD was administered orally to the diabetic rats (50\u00a0mg/kg b.wt.) daily for four weeks. In silico molecular docking was used to predict the interactions of PLD against BACE1 and AChE. PLD treatment significantly improved diabetic parameters, lowering blood glucose and raising serum insulin. Excitingly, PLD markedly alleviated oxidative stress by reducing lipid peroxidation and nitric oxide levels while enhancing antioxidant defenses (elevated GPx activity and GSH content) in the hippocampus of diabetic rats. PLD also suppressed neuroinflammation by down-regulating NF-\u03baB, COX-2, and IL-6 mRNA expression. Furthermore, PLD significantly elevated the protein level of IDE while lowered A\u03b21-42 level. In silico, PLD revealed potent binding affinity for BACE1 (-8.6 Kcal/mol) and AChE (-10.5 Kcal/mol), interacting with key residues, indicating its inhibition potential. Overall, PLD effectively reduced neurodegeneration in the hippocampus of diabetic rats via inhibiting oxidative stress, inflammation, and A\u03b21-42 accumulation. PLD may act as a promising multi-target anti-neurodegenerative candidate, capable of simultaneously modulating multiple pathways and more experimental validation are needed in the future.\n\nID: 42423799\nTitle: Cistanoside A decreases Tau hyperphosphorylation and neuronal apoptosis through the AKT/GSK3\u03b2 pathway in okadaic acid-induced in vivo and in vitro models of Alzheimer's disease.\nAbstract: The multifactorial nature of Alzheimer's disease (AD) pathogenesis has driven the search for therapeutic agents with low toxicity that can act on multiple targets. Cistanoside A (Cis A), a bioactive compound derived from Cistanches Herba, exhibits anti-inflammatory, antioxidant, and antiapoptotic effects. Given that these processes are implicated in AD progression, we propose that Cis A may be a promising candidate for AD therapy. We employed an okadaic acid (OA)-induced rat model in vivo and SH-SY5Y cells in vitro. Cognitive function was assessed using the Morris water maze and novel object recognition tests. Hematoxylin and eosin and Nissl staining were performed to evaluate histopathological changes. Neuronal damage was assessed using the Cell Counting Kit-8 assay for cell viability, TUNEL staining for apoptosis, and western blotting for protein expression. Mitochondrial damage was examined using JC-1 and MitoSOX Red staining. Cis A significantly improved cognitive deficits. It attenuated OA-induced apoptosis, restored mitochondrial membrane potential, and reduced reactive oxygen species levels in rats and SH-SY5Y cells by inhibiting hyperphosphorylation of Tau protein via the AKT/GSK3\u03b2 pathway. Furthermore, the protective effect of Cis A was attenuated by MK-2206 and AKT knockdown in vitro. Cis A significantly improves cognitive function and reduces AD-related pathology, highlighting its potential as a therapeutic candidate for AD.\n\nID: 42423424\nTitle: Adjunctive Minocycline in Acute Ischemic Stroke: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.\nAbstract: Acute ischemic stroke (AIS) is a leading cause of mortality and long-term disability worldwide. Despite advances in acute stroke management, many patients continue to experience substantial neurological disability and incomplete recovery. Minocycline, a tetracycline antibiotic with anti-inflammatory and neuroprotective properties and good blood-brain barrier penetration, has been investigated as a potential adjunctive therapy in AIS. A systematic search of major databases was conducted identifying randomized controlled trials evaluating minocycline in patients with AIS. Outcomes included functional and neurological recovery assessed using the modified Rankin Scale (mRS), National Institutes of Health Stroke Scale (NIHSS), and Barthel index (BI), as well as mortality and vascular events. Pooled effect estimates were calculated using random-effects meta-analysis. Seven RCTs comprising 2197 patients were included, with 1093 receiving minocycline and 1104 receiving placebo or standard care. Functional independence at 3 months (mRS 0-2) showed no significant difference between groups (RR 1.28, 95% CI 0.97-1.69; I2 = 84.9%). Minocycline was associated with lower NIHSS scores (MD -2.45, 95% CI -4.32 to -0.59; I2 = 88.6%) and higher BI scores (MD 12.52, 95% CI 6.28-18.76; I2 = 47.0%). Mortality (RR 0.66, 95% CI 0.39-1.090 and stroke recurrence or MI showed no significant differences (RR 0.97, 95% CI 0.69-1.37). Although a consistent improvement in functional independence was not demonstrated, minocycline showed signals of benefit in selected neurological outcomes with a favorable safety profile. These findings support the need for adequately powered, multicenter randomized trials to clarify its therapeutic role.\n\nID: 42420225\nTitle: Dose-Dependent Effects of Soy Lecithin Intake on Synaptic Ultrastructure in Brain Neurons and Behavioral Patterns of C57BL/6 Laboratory Mice.\nAbstract: Phospholipid preparations, including lecithin, are widely used as hepatoprotective and neuroprotective agents, while soy lecithin is intensively used in food industry, with its total dose in the modern human diet potentially reaching high levels. Soy lecithin contains up to 70% of biologically active phospholipids: phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidic acid. These compounds perform a spectrum of key cellular functions, including neuromediation processes, and ensure formation of the cellular membrane structures and vesicles. Previously, in the mouse model of chronic intestinal inflammation, behavioral changes were observed together with the significant increase in the relative content of several phospholipid classes in the intestinal epithelial cells. The animals fed with soy lecithin, which contains a mixture of these phospholipids, showed similar behavioral changes in the absence of inflammation: impaired social recognition and behavior, reduced signs of compulsivity and anxiety, and increased aggression in males. In this study, we found that reducing the dose of soy lecithin in short-term administration restores normal social recognition and behavior in the healthy C57BL/6 animals, while reduction in anxiety is maintained. Comparative electron microscopy analysis of the neurons and synapses in the amygdala, hypothalamus, and frontal motor cortex of the C57BL/6 animals treated with soy lecithin was conducted. Dose-dependent and region-specific changes were observed. High-dose lecithin administration, both long-term and short-term, reduced synapse density in the neuropil, and irregular synaptic vesicles were detected in the amygdala and hypothalamus. Threefold reduction in the lecithin dosage resulted in the increase in the number of vesicles per synapse in the hypothalamus and motor cortex. The obtained results demonstrate dose-dependent effect of soy lecithin on the synaptic ultrastructure in the hypothalamus, amygdala, and motor cortex of the frontal lobe, as well as on the behavioral patterns of the healthy C57BL/6 laboratory mice.\n\nID: 42419032\nTitle: Exogenous mitochondrial transplantation attenuates oxidative stress-driven retinal degeneration in a sodium iodate - induced mouse model.\nAbstract: Age-related macular degeneration (AMD) is a degenerative retinal disease initiated by dysfunction of the retinal pigment epithelium (RPE), in which age-related mitochondrial impairment, oxidative stress, chronic inflammation, and complement activation collectively drive outer retinal dysfunction and RPE atrophy, ultimately leading to progressive central vision loss. Accumulating evidence indicates that mitochondrial abnormalities, including excessive reactive oxygen species (ROS) production, mitochondrial fragmentation, and inflammatory signaling, play a central role in AMD pathogenesis. In this study, we investigated the therapeutic potential of exogenous mitochondrial transplantation using a sodium iodate (SI)-induced retinal degeneration model that recapitulates key pathological features of dry AMD. In ARPE-19 cells, SI-induced oxidative stress triggered mitochondrial fragmentation, inflammasome activation, and tight junction disruption, whereas delivery of mitochondria isolated from bone marrow-derived mesenchymal stem cells attenuated mitochondrial dysfunction and preserved RPE barrier integrity by suppressing oxidative and inflammatory signaling. Consistent with these in vitro findings, intravitreal mitochondrial transplantation in SI-treated mice attenuated RPE shedding/migration and outer nuclear layer disorganization while suppressing retinal oxidative stress, inflammatory cytokine expression, and complement activation. Importantly, mitochondrial transplantation mitigated the decline in retinal function, as assessed by electroretinography and optokinetic response testing, without fully restoring responses to control levels. Collectively, these results support exogenous mitochondrial transplantation as a promising cell-free therapeutic strategy to attenuate oxidative stress-driven retinal degeneration by modulating mitochondrial dysfunction and associated inflammatory pathways in AMD.\n\nID: 42418535\nTitle: Effect of Cosmos Caudatus supplementation and aerobic exercise on selected neurobehaviour, biochemical profile and histology in rats with mild cognitive impairment (MCI) induced by AlCl3: Study Protocol.\nAbstract: Cosmos caudatus (C. caudatus) or 'ulam raja' is a local plant with antioxidant properties and has the potential to act against oxidative-related conditions found such as in neurodegenerative diseases. Similarly, physical exercise is a consolidated strategy on the prevention of cognitive deficits. Based on the systematic review conducted by Joseph et al. (2023), a study protocol was developed to ensure the combined effect of C. caudatus supplementation and exercise provided improvement against cognitive impairment. There are limitations on studies looking at combined effect of flavonoid and exercise where either one of the interventions provided improvement to the behavioural tests and biomarkers assessed but not when given in combination. Moreover, to our understanding, in the last five years there has been limited research done on the combined effect of flavonoid and exercise against cognitive impairment (based on Pubmed search on 10 June 24; ScienceDirect search on 10 June 24). Therefore, we elucidated a study protocol that looks at the combined effect of C. caudatus supplementation and exercise against AlCl3-induced cognitive impairment in rats and the possible mechanisms involved in its neuroprotective effects in male rats. Male Wistar rats will be divided into different groups: control, physical exercise (treadmill running), supplemented with C. caudatus or in combination. Consequently, neurobehavioural tests (novel object recognition test, open field test & Y-maze), biochemical tests and histology assessment will be determined to unravel the possible neuroprotective capability against AlCl3-induced neurotoxicity. The duration of exercise training is four weeks while C. caudatus is supplemented for 21 days. The primary outcomes will be neurobehaviour changes at baseline, after 21 days of AlCl3-induced rats and at the end of intervention. While the secondary outcomes will be biochemical profile (Oxidative stress markers, inflammatory markers) and brain histology of AlCl3-induced rats. Combining exercise training with C. caudatus supplementation will produce synergistic effects, leading to significant improvements in spatial memory impairment and oxidative stress. This combined approach is expected to be more effective than using either intervention alone, potentially restoring spatial memory and antioxidant levels to normal. Consequently, the findings of this study could hold significant value for aging adults, providing safe and cost-effective strategies for managing neurodegenerative disorders.\n\nID: 42417497\nTitle: Targeting Autophagy in Alzheimer's Disease: Role of the AMPK/mTOR Pathway and Drug Repurposing.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by the accumulation of amyloid-\u03b2 (A\u03b2) plaques and tau (\u03c4) -related neurofibrillary tangles, often exacerbated by dysfunctional cellular clearance mechanisms. This manuscript explores the pivotal role of autophagy impairment in AD pathogenesis, with a specific focus on the AMPK/mTOR signaling axis as a primary regulatory pathway. Findings revealed that while mTOR overactivation suppresses autophagic flux and promotes the buildup of toxic protein aggregates, the activation of AMPK serves to restore homeostatic degradation processes. The review highlights that various pharmacological agent including rapamycin, metformin, trehalose, and curcumin, as well as repurposed drugs like lithium and statins can effectively enhance autophagy to ameliorate cognitive decline and neuroinflammation. Furthermore, herbal formulations such as Danggui Shaoyao San and phytoconstituents like Icariin demonstrate significant neuroprotective potential by modulating these same molecular pathways. Targeting autophagy represents a translationally viable approach for combating AD progression, with drug repurposing offering a time-efficient and cost-effective strategy. To advance these findings, future research should prioritize large-scale clinical trials to validate the efficacy of autophagy-inducing agents in human subjects. Additionally, investigating synergistic combinations of traditional bioactives with synthetic drugs and utilizing innovative delivery systems, such as intranasal nanotechnology-based platforms to bypass the blood-brain barrier, represents a promising frontier for developing effective, multi-targeted treatments against AD.\n\nID: 42416049\nTitle: GLP-1 receptor agonists in neurological diseases: mechanisms and therapeutic prospects from metabolism to neuroprotection.\nAbstract: Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are widely used metabolic therapies for type 2 diabetes and obesity, with well-established cardiovascular benefits. Beyond glycemic control, accumulating experimental and clinical evidence suggests that GLP-1RAs exert pleiotropic actions relevant to neurological diseases. Metabolic dysfunction, chronic inflammation, oxidative stress, mitochondrial impairment, and neurovascular injury represent convergent mechanisms that contribute to neurodegeneration, cerebrovascular pathology, and metabolism-related brain disorders. Notably, these processes overlap with pathways modulated by GLP-1 signaling across systemic and central compartments. GLP-1 receptors are expressed in neurons, glial cells, and components of the neurovascular unit, providing a biological basis for possible neurological effects. Preclinical studies suggest that GLP-1RAs can reduce neuroinflammation and oxidative stress, support mitochondrial function, and help maintain blood-brain barrier integrity. Clinical findings, however, remain inconsistent. Studies in Parkinson's disease have reported encouraging signals, but biomarker evidence for disease modification is still limited. In Alzheimer's disease, clinical trials have produced mixed or negative results. These differences may reflect disease stage, patient selection, drug-specific pharmacology, central nervous system exposure, endpoint sensitivity, and treatment duration. Overall, GLP-1RAs may influence neurological disease through metabolic, inflammatory, and vascular pathways, but their clinical role remains unsettled. Future studies should use biomarker-informed designs, prespecified neurological endpoints, appropriate drug selection, and sufficiently long follow-up to determine which patients and disease stages are most likely to benefit.\n\nID: 42414242\nTitle: Pharmacology, Medicinal Chemistry, and Therapeutic Potential of Imidazoline Receptor Ligands.\nAbstract: The imidazoline receptor (IR) system, comprising the I1R, I2R, and I3R subtypes, consists of binding sites involved in cardiovascular, metabolic, and neurological disorders. This review updates the 2004 compilation by Dardonville and Rozas on IR ligands, emphasizing promising ligands, subtype selectivity, and pharmacological profiling. Representative ligands for each subtype are analyzed to highlight key pharmacological aspects, including affinity, selectivity, and functional activity, integrating findings from preclinical and clinical studies. Critical molecular targets such as Nischarin/IRAS for I1R and MAO-B-associated sites for I2R are discussed in the context of ligand design and CNS penetration. I1R-selective ligands, exemplified by rilmenidine, show improved selectivity over \u03b12-adrenoceptors and exhibit antihypertensive, metabolic, and neuroprotective effects. I2R ligands display neuroprotective, anti-inflammatory, and analgesic activities, with CR4056 progressing to Phase II trials. PET imaging with [11C]BU99008 has validated I2R upregulation as a biomarker for neurodegeneration. Overall, the IR system presents therapeutic opportunities: I1R for cardiovascular and metabolic disorders, I2R for pain and neurodegeneration, and I3R for diabetes. Continued ligand optimization and receptor characterization are essential for clinical translation.\n\nID: 42413647\nTitle: DAla2-GIP-Glu-PAL exerts neuroprotective effect on diabetic retinopathy by attenuating microglia activation and regulating NF-\u03baB/NLRP3 and Nrf2/HO-1 pathways.\nAbstract: DAla2-GIP-Glu-PAL, a kind of analogue of glucose-dependent insulinotropic polypeptide (GIP), has neuroprotective effects in the central nervous system. Currently, retinal neurodegeneration is regarded as an important feature of diabetic retinopathy (DR). The objective of this study was to investigate the neuroprotective effect of DAla2-GIP-Glu-PAL on diabetic retinopathy (DR), and its possible mechanisms, including regulation of microglia activation, inflammatory response, and oxidative stress. In this study, Type 2 diabetic db/db mice and wild-type (WT) mice were used. The morphology and structure of the retina and the ganglion cell layer were observed using histological methods. The levels of PSD95, IL-1\u03b2, IL-18, pNrf2, HO-1, MDA, SOD, NF-\u03baBp65, NLRP3, Cleaved-Caspase-1, and GSDMD were detected to evaluate retinal oxidative stress and neuroinflammation, and to observe the changes in levels of these indicators after the intravitreal injection of DAla2-GIP-Glu-PAL. The findings demonstrated that db/db mice exhibited significant retinal pathological changes, loss of ganglion cells, decreased synaptic transmission function, and excessive activation of microglia. In addition, the levels of NF-\u03baBp65, NLRP3, Cleaved-Caspase-1, GSDMD, L-1\u03b2, IL-18, and MDA increased, while the levels of pNrf2, HO-1, and SOD decreased. DAla2-GIP-Glu-PAL reversed the excessive activation of microglia and the expression of indicators related to inflammatory responses and oxidative stress, promoting the recovery of retinal neural structure and function.These results imply that DAla2-GIP-Glu-PAL exerted a neuroprotective effect on diabetic retinopathy in mice by inhibiting excessive activation of microglia, inflammatory response, and oxidative stress. Its underlying mechanisms may involve downregulating the NF-\u03baB/NLRP3 pathway and upregulating the Nrf2/HO-1 pathway.\n\nID: 42411729\nTitle: The Dual Role of VEGF in Intracerebral Haemorrhage: From Pathological Mechanisms to Therapeutic Opportunities.\nAbstract: An intracerebral haemorrhage (ICH) is a general type of haemorrhage in the brain, which arises due to the rupture of cerebral blood vessels. Many molecules have been investigated for their potential ability to modify hemostasis and blood-brain barrier function in ICH. Vascular endothelial growth factor (VEGF) is highly expressed in some diseases and helps induce angiogenesis. VEGF serves as a key mediator of the angiogenic pathway and is now recognized as a major contributor to cerebrovascular diseases; many promising results have been obtained in animal therapeutic experiments. VEGF promotes blood vessel growth (angiogenesis) to increase oxygen and nutrient supply in damaged tissues, and exerts neuroprotective effects in processes including inflammation, apoptosis, neurotrophy, and protein clearance. This review examines the dual roles of VEGF in the pathology of ICH and explores therapeutic targets of VEGF pathways for this disease.\n\nID: 42411478\nTitle: Multi-Method Investigation of the Role of the PI3K/Akt Pathway in Sinomenine-Mediated Neuroprotection Against Acute Ischemic Stroke.\nAbstract: Effective neuroprotective therapies for acute ischemic stroke (AIS) remain limited due to the complex interplay between neuroinflammation and apoptosis. Sinomenine (Sino), a bioactive alkaloid derived from Sinomenium acutum, exhibits anti-inflammatory and anti-apoptotic activities; however, its molecular targets and mechanisms in AIS remain unclear. This study aimed to identify potential targets and key pathways of Sino and validate its neuroprotective effects in AIS. A combined approach integrating network pharmacology, Mendelian randomization (MR), molecular docking, and in vivo validation was adopted. Potential targets of Sino and ischemic stroke were identified using public databases. Overlapping targets were analyzed through protein-protein interaction network construction and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. Sprague-Dawley rats were randomly assigned to four groups, and a middle cerebral artery occlusion/reperfusion (MCAO/R) model was established (n = 12 per group): Sham, MCAO/R, Sino (20 mg/kg), and Sino +LY294002 (LY, 10 mg/kg). Sino and Sino + LY were administered intraperitoneally within 6 h after surgery and once daily thereafter for three days. Sham and MCAO groups were given the same amount of physiological saline undergoing the same procedures. Sino was administered intraperitoneally within 6 h after surgery and once daily thereafter for three days. Neurological deficits, infarct volume, neuronal injury, apoptosis, activation of the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) pathway, and inflammatory responses were assessed using behavioral tests, 2,3,5-Triphenyltetrazolium chloride (TTC)/Nissl/Terminal deoxynucleotidyl transferase dUTP Nick End Labeling (TUNEL) staining, Western blotting, immunofluorescence, enzyme-linked immunosorbent assay (ELISA). Twelve overlapping targets between Sino and ischemic stroke were identified, with Akt1 recognized as a central hub. Enrichment analysis highlighted the PI3K/Akt pathway as a critical signaling axis, while MR analysis indicated a nominal association between Akt1 and ischemic stroke. Molecular docking predicted stable binding between Sino and Akt1. In MCAO/R rats, Sino significantly improved neurological function, reduced infarct volumes, attenuated neuronal apoptosis, and increased neuronal survival. Mechanistically, Sino increased the p-PI3K/PI3K and p-Akt/Akt ratios, upregulated Bcl-2 expression, and decreased the expression of Bax, cleaved caspase-3, ionized calcium-binding adapter molecule 1 (Iba1), inducible nitric oxide synthase (iNOS), interleukin-1\u03b2 (IL-1\u03b2), interleukin-6 (IL-6), and tumor necrosis factor-\u03b1 (TNF-\u03b1). These beneficial effects were notably attenuated by LY. This study establishes PI3K/Akt as a functionally necessary mediator of Sino's neuroprotection against cerebral ischemia/reperfusion injury. The incomplete LY reversal indicates multi-target activity, supporting Sino's development as an adjunctive therapeutic candidate for ischemic stroke.\n\nID: 42411473\nTitle: Icariin Attenuates Neuroinflammation and Dopaminergic Degeneration in a Rodent Model of Parkinson's Disease by Promoting the Expansion of Regulatory T Cells.\nAbstract: Icariin, a bioactive flavonoid, exhibits significant neuroprotective properties and has emerged as a promising candidate for preventing neurodegenerative diseases, including Parkinson's disease (PD). However, the mechanism underlying its action is not fully understood. Enhancing the function and frequency of peripheral regulatory T cells (Tregs) may mitigate dopaminergic degeneration. This study investigates the role of Tregs in icariin's neuroprotective effects in a rodent model of PD. PD was induced in mice via stereotactic injection of 6-hydroxydopamine (6-OHDA). Mice underwent pretreatment with saline, icariin, an androgen receptor inhibitor (ARI), or a combination of icariin and ARI. Motor function was assessed in each experimental group, and dopaminergic neuronal injury was evaluated using immunohistochemistry (IHC) staining for tyrosine-hydroxylase (TH) in the substantia nigra (SN) and striatum. IHC was used to quantify CD4+ T-cell infiltration in the SN. Neuroinflammation was assessed through mRNA levels of the pro-inflammatory M1 phenotype of microglia, the anti-inflammatory M2 phenotype of microglia, and the levels of indicated pro-inflammatory cytokines in the SN. The frequency of Tregs among peripheral blood mononuclear cells (PBMCs) was analyzed by flow cytometry, and with Tregs were depleted using PC61 monoclonal antibodies. In vitro androgen receptor (AR) knockdown using shRNA in na\u00efve CD4+ T cells was performed to validate the AR-dependent mechanism. The results revealed that icariin significantly alleviated dopaminergic degeneration. Mechanistically, icariin promotes the expansion of peripheral neuroprotective and immunosuppressive Tregs, thereby restricting CD4+ T cell migration into the SN. This improvement in the inflammatory microenvironment reduced neuroinflammation and mitigated neurodegeneration. However, the neuroprotective and anti-inflammatory effects of icariin were lost when combined with ARI. Additionally, Treg depletion before 6-OHDA injection reversed the positive effects observed in the PD model. Icariin protects against neurodegeneration and neuroinflammation by boosting Tregs expansion in an androgen receptor-dependent manner.\n\nID: 42411435\nTitle: Small Extracellular Vesicles Derived From Mesenchymal Stem Cells Exert Neuroprotective Effect Against a Model of Dopamine Dysfunction by Inhibiting Caspase-8/Caspase-3-Mediated Apoptosis.\nAbstract: The precise pathological mechanisms driving Parkinson's disease (PD) progression remain incompletely understood, and there are currently no therapies that can modify the course of the disease. While mesenchymal stem cells (MSCs) hold therapeutic potential for various conditions, their clinical utility is constrained by challenges in sourcing and limited availability. This study investigated a novel therapeutic approach using trophoblast-derived mesenchymal-like stem cells (T-MSCs), which can be stably generated from commercially available embryonic stem cells, and the small extracellular vesicles (T-MSCs-sEVs) that they secrete. We explored the therapeutic effects against PD by inhibiting Caspase-8/Caspase-3-mediated apoptosis both in vitro and in vivo using experimental assays (e.g., flow cytometry (FCM) analysis, western blotting, and immunofluorescence staining). The selected cytokine Clusterin was validated via G-Series Mouse Cytokine Antibody Array 4000 (GSM-CAA-4000) using ELISA kits, which revealed its involvement in apoptosis during the PD process. Moreover, T-MSCs and T-MSCs-sEVs could alleviate dopaminergic (DA) neuron damage in vitro and in vivo by inhibiting the Caspase-8/Caspase-3-mediated apoptotic pathway. The results suggest that T-MSCs-sEVs represent a promising biological candidate for future therapeutic strategies aimed at treating PD.\n\nID: 42410910\nTitle: Targeting the SNAI1-LAMP3 axis to restore lysosomal function and alleviate autophagic flux impairment to delay retinal degeneration.\nAbstract: Retinal degenerative diseases are a leading cause of irreversible blindness. Their pathogenesis is intricately linked to oxidative stress-induced dysfunction of retinal pigment epithelial (RPE) cells and subsequent retinal degeneration. Macroautophagy/autophagy, a critical cellular degradation pathway, plays a vital role in maintaining RPE homeostasis, yet its dysregulation in retinal degenerative diseases remains poorly understood. In this study, we observed that sodium iodate (NaIO3), an oxidative stress inducer, triggered lysosomal dysfunction via lysosomal membrane permeabilization (LMP), thereby impairing autophagic flux in RPE cells and exacerbating retinal degeneration. RNA sequencing identified LAMP3 (lysosomal-associated membrane protein 3) as a downregulated gene following NaIO3 treatment. Functionally, LAMP3 overexpression alleviated NaIO3-induced LMP, improved lysosomal function, and alleviated autophagic impairment. Furthermore, upregulation of LAMP3 reduced oxidative stress and apoptosis in RPE cells, while alleviating retinal degeneration in a NaIO3-induced mouse model. Mechanistically, our data suggested that NaIO3 upregulated the transcription factor SNAI1, which acts as a transcriptional repressor of LAMP3. SNAI1 knockdown increased LAMP3 expression, thereby facilitating the recovery of lysosomal function and the alleviation of autophagic impairment. Collectively, our findings indicate that the SNAI1-LAMP3 axis contributes to the regulation of the autophagy-lysosomal pathway in retinal degeneration, highlighting a potential therapeutic target for delaying disease progression.Abbreviations: AMD: age-related macular degeneration; AO: acridine orange; Baf A1: bafilomycin A1; BAX: BCL2-associated X protein; BCL2: B cell leukemia/lymphoma 2; BSA: bovine serum albumin; CCK-8: cell counting kit-8; ChIP: chromatin immunoprecipitation; CM-H2DCFDA: chloromethyl-2',7'-dichlorodihydrofluorescein diacetate; CTSD: cathepsin D; DAPI: 4',6-diamidino-2-phenylindole; DEGs: differentially expressed genes; DHE: dihydroethidium; EdU: 5-ethynyl-2'-deoxyuridine; ERG: electroretinography; GSEA: gene set enrichment analysis; H&E: hematoxylin and eosin; HsRPE: human primary retinal pigment epithelial; JC-1: 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolylcarbocyanine iodide; LAMP1: lysosomal-associated membrane protein 1; LAMP2: lysosomal-associated membrane protein 2; LAMP3: lysosomal-associated membrane protein 3; LGALS3: lectin, galactose binding, soluble 3; LLOMe: leu-leu methyl ester; LMP: lysosomal membrane permeabilization; MAP1LC3B/LC3B: microtubule-associated protein 1 light chain 3 beta; MMP: mitochondrial membrane potential; NAC: N-acetyl-L-cysteine; NaIO3: sodium iodte; NC: negative control; OCT: optical coherence tomography; PCA: principal component analysis; PI: propidium iodide; qRT-PCR: quantitative real-time polymerase chain reaction; Rapa: rapamycin; ROS: reactive oxygen species; RP: retinitis pigmentosa; RPE: retinal pigment epithelium; RPE65: retinal pigment epithelium 65; siRNA: small interfering RNA; SNAI1: snail family zinc finger 1; SQSTM1/p62: sequestosome 1; TJP1/ZO-1: tight junction protein 1; ZNF135: zinc finger protein 135.\n\nID: 42207197\nTitle: Caffeic acid restores neurogenesis and synaptic integrity under glucolipotoxic stress by suppressing inflammation and pyroptosis.\nAbstract: Diabetes mellitus is frequently associated with cognitive dysfunction, primarily attributed to impaired hippocampal neurogenesis, oxidative stress, inflammation, and pyroptosis. Caffeic acid (CA), a dietary polyphenol, has demonstrated antioxidant and neuroprotective effects. This study evaluated the protective role of CA under diabetic-like conditions using an in vitro glucolipotoxicity model in HT-22 hippocampal neurons exposed to high glucose and oleic acid (HG\u2009+\u2009OA). CA was administered at low (5 \u00b5M) and high (25 \u00b5M) concentrations prior to HG\u2009+\u2009OA treatment. CA significantly enhanced neuronal viability and restored the expression of neurogenesis markers (Nestin, DCX, NeuN) and synaptic proteins (PSD-95, Synaptophysin). Furthermore, CA elevated antioxidant enzyme levels (Nrf2, catalase, SOD-1), regulated apoptosis through increased Bcl-2 and decreased BAX expression, and attenuated inflammatory responses. Pyroptosis was also suppressed, as evidenced by reduced gasdermin D (GSDMD) expression. These findings suggest that CA confers multifactorial neuroprotection against glucolipotoxic injury, and may serve as a dietary modulator for mitigating diabetes-associated cognitive decline in vitro.\n\nID: 42156489\nTitle: Longitudinal effect of glycaemic variability on retinal neurodegeneration and neuropathic characteristics in paediatric patients with type 1 diabetes mellitus.\nAbstract: Retinal neurodegeneration (RN) is an early marker of diabetic retinopathy, preceding vascular damage. The aims of our study are to evaluate the three-year progression of neuroretinal structure, the association between early alterations and diabetic neuropathy (DN) and the predictive role of glycaemic variability (GV) in this progression in paediatric type 1 diabetes mellitus (T1DM) subjects. Twenty-five paediatric T1DM patients, using Continuous Glucose Monitoring (CGM) and treated with continuous subcutaneous insulin infusion, without any complication, and eighteen controls (C) were enrolled and followed for three years. All subjects underwent an Optical Coherence Tomography, with analysis of neuroretinal layers. In T1DM patients, metabolic parameters, GV indexes, standardised CGM metric, peripheral and autonomic assessment were investigated. All the data were collected at baseline and every 12 months. Starting from the baseline, Retinal Nerve Fiber Layer thickness and Outer Plexiform Layer (OPL) became significantly thinner in T1DM versus C. In T1DM patients, negative correlations were observed between GV and all the inner retinal layers and positive correlations were observed between TIR and OPL. No significant correlations between HbA1c and macular layer thickness were observed. At V3, positive correlations between the retinal variation and neuropathic indexes were observed. Early morphological alterations of neuroretina are already present in paediatric T1DM patients without complications. There is a possible association between these alterations and early signs of DN. These data corroborate the hypothesis that RN is an early sign of DN and GV should be effectively addressed in the early stage of T1DM.\n\nID: 42086968\nTitle: MiR-144 Regulates Cognitive Dysfunction via NLRP3 Inflammasome and FoxO1/AdipoR Pathway in T2DM Mice.\nAbstract: Type 2 diabetes mellitus (T2DM) is closely related to cognitive impairment, with underlying pathological mechanisms including chronic inflammation, synaptic dysfunction, and microglial dysregulation. Although microRNA-144 (miR-144) has been implicated in these processes, its precise role and molecular mechanisms remain unclear. T2DM mouse models were established using a high-fat diet combined with low-dose streptozotocin, and microglia-specific miR-144 intervention was achieved in the hippocampus via bilateral injection of adeno-associated virus. Cognitive function was assessed using the novel object recognition and Morris water maze tests, while synaptic plasticity, microglial phenotype, neuroinflammation, and Tau pathology were evaluated by immunofluorescence, Western blot, Golgi staining, transmission electron microscopy, and electrophysiology. Our results showed that overexpression of miR-144 mimicked the pathological state of T2DM, leading to impaired learning and memory, neuronal dysfunction, reduced expression of synaptic proteins, and decreased dendritic spine density. Additionally, miR-144 overexpression significantly suppressed FoxO1 and AdipoR1/AdipoR2 expression while inducing microglial M1 polarization, activating downstream NLRP3-mediated neuroinflammatory responses, and increasing Tau phosphorylation. Conversely, miR-144 knockdown effectively ameliorated these pathological changes and provided neuroprotection. These findings suggest that miR-144 could serve as a promising biomarker and therapeutic target for T2DM-related cognitive impairment. This study offers novel insights into the underlying mechanisms of T2DM-related cognitive impairment and provides an experimental foundation for exploring miR-144-based intervention strategies.\n\nID: 41926615\nTitle: Loss of ovarian function and estrogen therapy remodel the brain's synaptic and metabolic proteome.\nAbstract: Menopause is linked to cognitive decline and reduced brain metabolism, whereas estrogen (E2) therapy has been shown to mitigate these effects. Understanding the molecular mechanisms by which ovarian hormones and E2 influence neuroprotection is essential for developing strategies to maintain brain health in women. In this study, we examined how the loss of ovarian hormones, with or without E2 treatment, affects the brain proteome and mitochondrial energy production in aged female C57BL/6J mice (36-40 wk). The mice underwent sham or ovariectomy (OVX) surgery and were fed a high-fat diet for 10 wk; 6 wk after surgery, OVX mice received either sesame oil or E2 treatment for 4 wk. Proteomic analysis of brain homogenates revealed 4,992 proteins regulated by E2, with pathway analysis showing increased signaling proteins related to synaptogenesis. OVX reduced proteins involved in synaptic function, branched-chain amino acid and ketone metabolism, the tricarboxylic acid cycle, and oxidative phosphorylation (Complexes I, IV, and V), whereas E2 restored protein expression within these pathways. Despite alterations in OxPhos proteins, basal and state 3 mitochondrial respiration remained unchanged, although notable impairments in Complex IV enzymatic activity were apparent in OVX, which were partially reversed by E2 treatment. Overall, these results indicate that E2 supports brain health by maintaining proteins crucial for synaptic integrity and metabolism, while partially offsetting the functional decline in mitochondrial bioenergetics associated with menopause.NEW & NOTEWORTHY The menopausal transition, marked by declining estrogen levels, alters cognition, neuroplasticity, and brain metabolism. Although hormone therapy benefits cognition, its molecular effects on the brain remain unclear. Using whole-brain proteomics in aged ovariectomized (OVX) mice with or without estrogen treatment, we found that OVX reduced proteins linked to synaptogenesis and mitochondrial metabolism. Estrogen reversed these declines, restoring pathways supporting neuronal signaling and energy balance, identifying estrogen-regulated proteins critical for maintaining brain health during menopause.\n\nID: 40860138\nTitle: Intermittent fasting reprograms the brain proteome to prevent synaptic degeneration and cognitive impairment in vascular dementia.\nAbstract: Rationale: Vascular dementia (VaD), driven by chronic cerebral hypoperfusion (CCH), leads to synaptic degeneration and cognitive decline, yet mechanisms linking vascular dysfunction to synaptic loss remain unclear. Intermittent fasting (IF) has emerged as a potential intervention, but its effects on synaptic integrity in VaD are unknown. This study aims to investigate the effects of IF against synaptic degeneration and cognitive impairment induced by CCH. Methods: Bilateral common carotid artery stenosis (BCAS) was employed to induce chronic CCH by placing 0.18 mm micro-coils around each common carotid artery in mice. To assess temporal differences, the coils remained in place for 1, 7, 14, or 30 days. IF was implemented for 16 hours daily over three months prior to BCAS induction. Cognitive impairment was evaluated using the Barnes maze test. White matter lesions (WMLs) and neuronal loss were assessed using Luxol fast blue and cresyl violet staining, respectively. Immunoblotting and immunohistochemistry were performed to quantify synaptic protein levels. Synaptic integrity was examined using transmission electron microscopy. Proteomic analysis of the hippocampus was conducted to investigate molecular adaptations to IF following CCH. Results: We demonstrate that a 16-hour IF regimen preserves cognitive function and synaptic density despite persistent hypoperfusion. Behavioral assays revealed that IF prevented spatial memory deficits in BCAS mice, while electron microscopy confirmed synaptic preservation without altering baseline architecture. Surprisingly, key synaptic protein levels remained unchanged, suggesting IF protects synaptic function rather than abundance. Proteomic profiling revealed dynamic hippocampal adaptations under IF, including upregulation of synaptic stabilizers, enhanced GABAergic signaling, and suppression of neuroinflammatory mediators. CCH induced microglial engulfment of synapses, suggesting a role in complement-mediated synaptic pruning. Temporal pathway analysis revealed IF's multi-phase neuroprotection: early synaptic reinforcement, mid-phase metabolic optimization, and late-phase suppression of chronic neuroinflammation. Conclusion: These findings establish IF as a potent modulator of synaptic resilience in VaD, acting through coordinated preservation of synaptic structure, inhibition of inflammatory synapse loss, and metabolic reprogramming. Our results highlight IF's potential as a non-pharmacological strategy to combat vascular cognitive impairment by targeting the synaptic vulnerability underlying dementia progression.\n\nID: 40175519\nTitle: Sulforaphane protects developing neural networks from VPA-induced synaptic alterations.\nAbstract: Prenatal brain development is particularly sensitive to chemicals that can disrupt synapse formation and cause neurodevelopmental disorders. In most cases, such chemicals increase cellular oxidative stress. For example, prenatal exposure to the anti-epileptic drug valproic acid (VPA), induces oxidative stress and synaptic alterations, promoting autism spectrum disorders (ASD) in humans and autism-like behaviors in rodents. Using VPA to model chemically induced ASD, we tested whether activation of cellular mechanisms that increase antioxidant gene expression would be sufficient to prevent VPA-induced synaptic alterations. As a master regulator of cellular defense pathways, the transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) promotes expression of detoxification enzymes and antioxidant gene products. To increase NRF2 activity, we used the phytochemical and potent NRF2 activator, sulforaphane (SFN). In our models of human neurodevelopment, SFN activated NRF2, increasing expression of antioxidant genes and preventing oxidative stress. SFN also enhanced expression of genes associated with synapse formation. Consistent with these gene expression profiles, SFN protected developing neural networks from VPA-induced reductions in synapse formation. Furthermore, in mouse cortical neurons, SFN rescued VPA-induced reductions in neural activity. These results demonstrate the ability of SFN to protect developing neural networks during the vulnerable period of synapse formation, while also identifying molecular signatures of SFN-mediated neuroprotection that could be relevant for combatting other environmental toxicants.\n\nID: 40016944\nTitle: The Effect of Advancing Age and Intraocular Pressure Injury on Retinal Ganglion Cell Function and Synaptic Connectivity.\nAbstract: Age and elevated intraocular pressure (IOP) are the two major risk factors for developing glaucoma, a leading cause of blindness worldwide that is characterized by the loss of retinal ganglion cells (RGCs). Although vision loss is irreversible over the long term, accumulating evidence points to short-term improvement of vision in glaucoma patients in response to certain interventions, suggesting that RGCs have the capacity to recover function. In the present study, we sought to investigate the mechanisms underlying loss and recovery of RGC function in response to aging and IOP injury, with a focus on synaptic connectivity. Using electroretinography, we found that advancing age was associated with a substantial reduction in function across all retinal layers in the absence of significant cell loss. A superimposed injury induced by IOP elevation led to the selective loss of RGC function in young and middle-aged mice that was associated with a decrease in paired excitatory synapses. RGC functional recovery after injury was significantly delayed in middle-aged mice and was mediated through different cellular mechanisms than in young mice. Whereas young mice regained excitatory synaptic inputs from bipolar cells, functional recovery in older mice was instead mediated through an increase in intrinsic RGC excitability, associated with modulation of the action potential threshold and axon initial segment length. Our findings provide new insights into the impact of advancing age on RGC resilience to IOP injury. Boosting the capacity for RGC recovery by reversing the effect of advancing age offers a new therapeutic approach for glaucoma management.\n\nID: 39824188\nTitle: Transplantation of genome-edited retinal organoids restores some fundamental physiological functions coordinated with severely degenerated host retinas.\nAbstract: We have previously shown that the transplantation of stem cell-derived retinal organoid (RO) sheets into animal models of end-stage retinal degeneration can lead to host-graft synaptic connectivity and restoration of vision, which was further improved using genome-edited Islet1-/- ROs (gROs) with a reduced number of ON-bipolar cells. However, the details of visual function restoration using this regenerative therapeutic approach have not yet been characterized. Here, we evaluated the electrophysiological properties of end-stage rd1 retinas after transplantation (TP-rd1) and compared them with those of wild-type (WT) retinas using multi-electrode arrays. Notably, retinal ganglion cells (RGCs) in TP-rd1 retinas acquired light sensitivity comparable to that of WT retinas. Furthermore, RGCs in TP-rd1 retinas showed light adaptation to a photopic background and responded to flickering stimuli. These results demonstrate that transplantation of gRO sheets may restore some fundamental physiological functions, possibly coordinating with the remaining functions in retinas with end-stage degeneration.\n\nID: 38896876\nTitle: Electrophysiological Analysis of Retinal Organoid Development Using 3D Microelectrodes of Liquid Metals.\nAbstract: Despite of the substantial potential of human-derived retinal organoids, the degeneration of retinal ganglion cells (RGCs) during maturation limits their utility in assessing the functionality of later-born retinal cell subtypes. Additionally, conventional analyses primarily rely on fluorescent emissions, which limits the detection of actual cell functionality while risking damage to the 3D cytoarchitecture of organoids. Here, an electrophysiological analysis is presented to monitor RGC development in early to mid-stage retinal organoids, and compare distinct features with fully-mature mouse retina. This approach utilizes high-resolution 3D printing of liquid-metal microelectrodes, enabling precise targeting of specific inner retinal layers within organoids. The adaptable distribution and softness of these microelectrodes facilitate the spatiotemporal recording of inner retinal signals. This study not only demonstrates the functional properties of RGCs in retinal organoid development but also provides insights into their synaptic connectivity, reminiscent of fetal native retinas. Further comparison with fully-mature mouse retina in vivo verifies the organoid features, highlighting the potential of early-stage retinal organoids in biomedical research.\n\nID: 38857169\nTitle: Deciphering the genetic code of neuronal type connectivity through bilinear modeling.\nAbstract: Understanding how different neuronal types connect and communicate is critical to interpreting brain function and behavior. However, it has remained a formidable challenge to decipher the genetic underpinnings that dictate the specific connections formed between neuronal types. To address this, we propose a novel bilinear modeling approach that leverages the architecture similar to that of recommendation systems. Our model transforms the gene expressions of presynaptic and postsynaptic neuronal types, obtained from single-cell transcriptomics, into a covariance matrix. The objective is to construct this covariance matrix that closely mirrors a connectivity matrix, derived from connectomic data, reflecting the known anatomical connections between these neuronal types. When tested on a dataset of Caenorhabditis elegans, our model achieved a performance comparable to, if slightly better than, the previously proposed spatial connectome model (SCM) in reconstructing electrical synaptic connectivity based on gene expressions. Through a comparative analysis, our model not only captured all genetic interactions identified by the SCM but also inferred additional ones. Applied to a mouse retinal neuronal dataset, the bilinear model successfully recapitulated recognized connectivity motifs between bipolar cells and retinal ganglion cells, and provided interpretable insights into genetic interactions shaping the connectivity. Specifically, it identified unique genetic signatures associated with different connectivity motifs, including genes important to cell-cell adhesion and synapse formation, highlighting their role in orchestrating specific synaptic connections between these neurons. Our work establishes an innovative computational strategy for decoding the genetic programming of neuronal type connectivity. It not only sets a new benchmark for single-cell transcriptomic analysis of synaptic connections but also paves the way for mechanistic studies of neural circuit assembly and genetic manipulation of circuit wiring.\n\nID: 38632569\nTitle: Complement propagates visual system pathology following traumatic brain injury.\nAbstract: Traumatic brain injury (TBI) is associated with the development of visual system disorders. Visual deficits can present with delay and worsen over time, and may be associated with an ongoing neuroinflammatory response that is known to occur after TBI. Complement system activation is strongly associated with the neuroinflammatory response after TBI, but whether it contributes to vision loss after TBI is unexplored. Acute and chronic neuroinflammatory changes within the dorsal lateral geniculate nucleus (dLGN) and retina were investigated subsequent to a moderate to severe murine unilateral controlled cortical impact. Neuroinflammatory and histopathological outcomes were interpreted in the context of behavioral and visual function data. To investigate the role of complement, cohorts were treated after TBI with the complement inhibitor, CR2-Crry. At 3 days after TBI, complement component C3 was deposited on retinogeniculate synapses in the dLGN both ipsilateral and contralateral to the lesion, which was reduced in CR2-Crry treated animals. This was associated with microglia morphological changes in both the ipsilateral and contralateral dLGN, with a less ramified phenotype in vehicle compared to CR2-Crry treated animals. Microglia in vehicle treated animals also had a greater internalized VGlut2\u2009+\u2009synaptic volume after TBI compared to CR2-Crry treated animals. Microglia morphological changes seen acutely persisted for at least 49\u00a0days after injury. Complement inhibition also reduced microglial synaptic internalization in the contralateral dLGN and increased the association between VGLUT2 and PSD95 puncta, indicating preservation of intact synapses. Unexpectedly, there were no changes in the thickness of the inner retina, retinal nerve fiber layer or retinal ganglion layer. Neuropathological changes in the dLGN were accompanied by reduced visual acuity at subacute and chronic time points after TBI, with improvement seen in CR2-Crry treated animals. TBI induces complement activation within the dLGN and promotes microglial activation and synaptic internalization. Complement inhibition after TBI in a clinically relevant paradigm reduces complement activation, maintains a more surveillance-like microglia phenotype, and preserves synaptic density within the dLGN. Together, the data indicate that complement plays a key role in the development of visual deficits after TBI via complement-dependent microglial phagocytosis of synapses within the dLGN.\n\nID: 38103230\nTitle: Glucagon-like peptide 1 receptor activation: anti-inflammatory effects in the brain.\nAbstract: The glucagon-like peptide 1 is a pleiotropic hormone that has potent insulinotropic effects and is key in treating metabolic diseases such as diabetes and obesity. Glucagon-like peptide 1 exerts its effects by activating a membrane receptor identified in many tissues, including different brain regions. Glucagon-like peptide 1 activates several signaling pathways related to neuroprotection, like the support of cell growth/survival, enhancement promotion of synapse formation, autophagy, and inhibition of the secretion of proinflammatory cytokines, microglial activation, and apoptosis during neural morphogenesis. The glial cells, including astrocytes and microglia, maintain metabolic homeostasis and defense against pathogens in the central nervous system. After brain insult, microglia are the first cells to respond, followed by reactive astrocytosis. These activated cells produce proinflammatory mediators like cytokines or chemokines to react to the insult. Furthermore, under these circumstances, microglia can become chronically inflammatory by losing their homeostatic molecular signature and, consequently, their functions during many diseases. Several processes promote the development of neurological disorders and influence their pathological evolution: like the formation of protein aggregates, the accumulation of abnormally modified cellular constituents, the formation and release by injured neurons or synapses of molecules that can dampen neural function, and, of critical importance, the dysregulation of inflammatory control mechanisms. The glucagon-like peptide 1 receptor agonist emerges as a critical tool in treating brain-related inflammatory pathologies, restoring brain cell homeostasis under inflammatory conditions, modulating microglia activity, and decreasing the inflammatory response. This review summarizes recent advances linked to the anti-inflammatory properties of glucagon-like peptide 1 receptor activation in the brain related to multiple sclerosis, Alzheimer's disease, Parkinson's disease, vascular dementia, or chronic migraine.\n\nID: 37500494\nTitle: Ultrastructure of Synaptic Connectivity within Subregions of the Suprachiasmatic Nucleus Revealed by a Genetically Encoded Tag and Serial Blockface Electron Microscopy.\nAbstract: The hypothalamic suprachiasmatic nucleus (SCN) is the central circadian pacemaker in vertebrates. The SCN receives photic information exclusively through melanopsin-expressing retinal ganglion cells (mRGCs) to synchronize circadian rhythms with the environmental light cycles. The SCN is composed of two major peptidergic neuron types in the core and shell regions of the SCN. Determining how mRGCs interact with the network of synaptic connections onto and between SCN neurons is key to understand how light regulates the circadian clock and to elucidate the relevant local circuits within the SCN. To map these connections, we used a newly developed Cre-dependent electron microscopy (EM) reporter, APEX2, to label the mitochondria of mRGC axons. Serial blockface scanning electron microscopy was then used to resolve the fine 3D structure of mRGC axons and synaptic boutons in the SCN of a male mouse. The resulting maps reveal patterns of connectomic organization in the core and shell of the SCN. We show that these regions are composed of different neuronal subtypes and differ with regard to the pattern of mRGC input, as the shell receives denser mRGC synaptic input compared with the core. This finding challenges the present view that photic information coming directly from the retina is received primarily by the core region of the SCN.\n\nID: 36598946\nTitle: Re-formation of synaptic connectivity in dissociated human stem cell-derived retinal organoid cultures.\nAbstract: Human pluripotent stem cell (hPSC)-derived retinal organoids (ROs) can efficiently and reproducibly generate retinal neurons that have potential for use in cell replacement strategies [Capowski et al., Development\u00a0146, dev171686 (2019)]. The ability of these lab-grown retinal neurons to form new synaptic connections after dissociation from ROs is key to building confidence in their capacity to restore visual function. However, direct evidence of reestablishment of retinal neuron connectivity via synaptic tracing has not been reported to date. The present study employs an in\u00a0vitro, rabies virus-based, monosynaptic retrograde tracing assay [Wickersham et al., Neuron\u00a053, 639-647\u00a0(2007); Sun et al., Mol. Neurodegener.\u00a014,\u00a08\u00a0(2019)] to identify de novo synaptic connections among early retinal cell types following RO dissociation. A reproducible, high-throughput approach for labeling and quantifying traced retinal cell types was developed. Photoreceptors and retinal ganglion cells-the primary neurons of interest for retinal cell replacement-were the two major contributing populations among the traced presynaptic cells. This system provides a platform for assessing synaptic connections in cultured retinal neurons and sets the stage for future cell replacement studies aimed at characterizing or enhancing synaptogenesis. Used in this manner, in\u00a0vitro synaptic tracing is envisioned to complement traditional preclinical animal model testing, which is limited by evolutionary incompatibilities in synaptic machinery inherent to human xenografts.\n\nID: 34916418\nTitle: Homer signaling pathways as effective therapeutic targets for ischemic and traumatic brain injuries and retinal lesions.\nAbstract: Ischemic and traumatic insults to the central nervous system account for most serious acute and fatal brain injuries and are usually characterized by primary and secondary damage. Secondary damage presents the greatest challenge for medical staff; however, there are currently few effective therapeutic targets for secondary damage. Homer proteins are postsynaptic scaffolding proteins that have been implicated in ischemic and traumatic insults to the central nervous system. Homer signaling can exert either positive or negative effects during such insults, depending on the specific subtype of Homer protein. Homer 1b/c couples with other proteins to form postsynaptic densities, which form the basis of synaptic transmission, while Homer1a expression can be induced by harmful external factors. Homer 1c is used as a unique biomarker to reveal alterations in synaptic connectivity before and during the early stages of apoptosis in retinal ganglion cells, mediated or affected by extracellular or intracellular signaling or cytoskeletal processes. This review summarizes the structural features, related signaling pathways, and diverse roles of Homer proteins in physiological and pathological processes. Upregulating Homer1a or downregulating Homer1b/c may play a neuroprotective role in secondary brain injuries. Homer also plays an important role in the formation of photoreceptor synapses. These findings confirm the neuroprotective effects of Homer, and support the future design of therapeutic drug targets or gene therapies for ischemic and traumatic brain injuries and retinal disorders based on Homer proteins.\n\nID: 34698774\nTitle: Morphometric and Microstructural Changes During Murine Retinal Development Characterized Using In Vivo Optical Coherence Tomography.\nAbstract: The purpose of this study was to develop an in vivo optical coherence tomography (OCT) system capable of imaging the developing mouse retina and its associated morphometric and microstructural changes. Thirty-four wild-type mice (129S1/SvlmJ) were anesthetized and imaged between postnatal (P) day 7 and P21. OCT instrumentation was developed to optimize signal intensity and image quality. Semi-automatic segmentation tools were developed to quantify the retinal thickness of the nerve fiber layer (NFL), inner plexiform layer (IPL), inner nuclear layer (INL), and the outer retinal layers (ORL), in addition to the total retina. The retinal maturation was characterized by comparing layer thicknesses between consecutive time points. From P7 to P10, the IPL increased significantly, consistent with retinal synaptogenesis. From P10 to P12, the IPL and ORL also increased, which is coherent with synaptic connectivity and photoreceptor maturation. In contrast, during these periods, the INL decreased significantly, consistent with cellular densification and selective apoptotic \"pruning\" of the tissue during nuclear migration. Thereafter from P12 to P21, the INL continued to thin (significantly from P17 to P21) whereas the other layers remained unchanged. No time-dependent changes were observed in the NFL. Overall, changes in the total retina were attributed to those in the IPL, INL, and ORL. Regions of the retina adjacent to the optic nerve head were thinner than distal regions during maturation. Changes in retinal layer thickness are consistent with retinal developmental mechanisms. Accordingly, this report opens new horizons in using our system in the mouse to characterize longitudinally developmental digressions in models of human diseases.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

This study sought to determine the effects of pelargonidin on extracellular matrix (ECM) modulation and the inhibition of transforming growth factor-\u03b2 (TGF-\u03b2) and Janus Kinase 2/Signal Transducer and Activator of Transcription 3 (JAK2/STAT3) pathway in retinal ganglion cells of streptozotocin-induced diabetic rats. Male Sprague-Dawley rats (180-200 g) were rendered diabetic by intraperitoneal administration of streptozotocin (STZ). The rats were divided into 5 groups: control, diabetic model (STZ), STZ + low dose pelargonidin (12.5 mg kg-1 per day), STZ + medium dose pelargonidin (25 mg kg-1 per day) and STZ + high dose pelargonidin (50 mg kg-1 per day). IOP was monitored using a tonometer. Whole-mount retinal immunofluorescence staining using RNA-binding protein with multiple splicing (RBPMS) was performed to assess retinal ganglion cell (RGC) density. Protein expression levels of apoptotic markers, ECM components, and TGF-\u03b2 and JAK2/STAT3 signalling pathways were evaluated by Western blotting. Pelargonidin treatment dose-dependently reduced the elevated IOP. Importantly, immunofluorescence analysis revealed a marked dose-dependent preservation of retinal ganglion cell (RGC) density: STZ-induced RGC loss was significantly reversed by pelargonidin, with the highest dose restoring RGC density to near-control or higher levels in both the central and peripheral retina. This was achieved via modulation of apoptosis-related proteins through the upregulation of Bcl-xL, Bcl-2, and downregulation of Bad, Bax and cleaved caspase-3. Furthermore, pelargonidin modulated ECM remodelling protein expression in the RGC layer. In particular, TGF-\u03b22/Smad2/3 signalling was downregulated, and the JAK2/STAT3 pathway was upregulated. By reducing IOP, preserving RGC density, modulating ECM deposition, inhibiting TGF-\u03b2 and upregulating the JAK2/STAT3 pathway, pelargonidin exerts protective effects against diabetic retinal injury. The results of this study further confirm the pharmacological potential of pelargonidin as a therapeutic agent for diabetic retinopathy.\n  --- END ACTUAL ABSTRACT FOR 41963265 ---\n\n- ERROR: You cited ID: 41750392 for the quote: \"notably, novel agents that enhance spinogenesis by acting at the level of PSD proteins, such as SPG302, may open promising avenues for therapeutics aimed at restoring synaptic integrity.\"\n  FACT: Strict Misquote Detected!

Group I mGluRs (mGluR1 and mGluR5) interact with PSD adaptor and scaffolding proteins, such as Homer, Shank, Norbin, and PICK1, as well as intracellular downstream effectors, creating a molecular network that resembles a Lego-like structure, where modular protein interactions fine-tune glutamatergic transmission. Evidence from preclinical research indicates that dysregulation of mGluR expression and function, along with disrupted PSD protein expression, may contribute to the pathophysiology of schizophrenia by altering glutamatergic neurotransmission and synaptic stability. Antipsychotic mechanisms of action may involve, at least in part, the modulation of mGluR activity mediated through PSD proteins. Notably, novel agents that enhance spinogenesis by acting at the level of PSD proteins, such as SPG302, may open promising avenues for therapeutics aimed at restoring synaptic integrity. While Group I mGluRs dominate postsynaptic regulation, Group II (mGluR2/3) and III (mGluR4/6/7/8) receptors -primarily presynaptic- inhibit neurotransmitter release and plasticity, offering complementary therapeutic avenues. Emerging strategies, such as allosteric modulators of mGluRs, aim to rebalance synaptic signaling in treatment-resistant schizophrenia. This review synthesizes how PSD proteins and mGluRs interact in schizophrenia, exploring their potential as druggable targets for novel therapies.\n  --- END ACTUAL ABSTRACT FOR 41750392 ---\n\n- ERROR: You cited ID: 41237937 for the quote: \"Oral gavage of l-aspartic acid \u03b2-hydroxamate (L-ABH) improved b-wave amplitudes in electroretinogram recordings...

Studies, including our own, demonstrate that SRR is linked to a complication of diabetes, diabetic retinopathy (DR), and deletion of Srr protects diabetic animals from developing retinopathy. We investigate the feasibility and mechanisms of SRR inhibition as a strategy to prevent DR. SRR proteins in the retinas of db/db mice were approximately 50&nbsp;% higher than C57BLKS/J wild-type (WT) mice, while D-serine levels in the aqueous humor were more than two-fold higher. Oral gavage of l-aspartic acid \u03b2-hydroxamate (L-ABH) improved b-wave amplitudes in electroretinogram recordings under both photopic and scotopic conditions. It also protected the inner retina in db/db mice by reducing the loss of retinal ganglion cells, endothelial cells, and pericytes, as well as decreasing the activation of M\u00fcller cells. In high glucose and hypoxia, interleukin-1 and interleukin-18 mRNA levels were lower in Srr-deleted M\u00fcller cell cultures than in WT cultures. Intravitreal injection of L-ABH mitigated glutamate-induced neurotoxicity in the retina. Systemically, L-ABH maintained euglycemia and improved glucose tolerance in db/db mice by inhibiting liver gluconeogenesis through restricting the expansion of pancreatic islet \u03b1-cells. Altogether, our results demonstrate that SRR inhibition prevents retinopathy in diabetic animals by blocking excitotoxicity and M\u00fcller cell-mediated inflammation in the retina, while also maintaining glucose homeostasis. This is the first demonstration that pharmacological blockade of SRR improves retinopathy and normalizes glucose levels in a type 2 diabetes model.\n  --- END ACTUAL ABSTRACT FOR 41237937 ---\n\n- ERROR: You cited ID: 40759398 for the quote: \"Suppression of the miR-122-5p gene safeguards RGCs against harm caused by HG via boosting SIRT3 signaling, which might provide a new prevention and treatment strategy for DR.\"\n  FACT: Strict Misquote Detected!

DJ-1 (PARK7) acts as a crucial antioxidant defense mechanism, stabilizing mitochondrial structure and redox balance. However, its expression is dramatically suppressed under diabetic conditions, and the upstream regulatory mechanisms remain incompletely characterized. Growing evidence from epigenetic research implicates microRNAs (miRNAs) as important players in the molecular pathways underlying DR progression. Among these, miRNA-122-5p has drawn increasing attention due to its aberrant activity under diabetic stress and its putative interaction with PARK7. In this study, we employed a streptozotocin-induced type 1 diabetes mouse model and glucose-stimulated R28&nbsp;cells to explore the contribution of miRNA-122-5p to mitochondrial damage, oxidative stress, and RGC injury. In diabetic mice, we observed significant oxidative imbalance, increased apoptotic activity, RGC loss, and diminished retinal function. MiRNA profiling identified miRNA-122-5p as the most upregulated among candidate miRNAs. Inhibition of miRNA-122-5p attenuated these pathological changes and preserved both cellular integrity and visual function. In vitro, high glucose triggered mitochondrial fragmentation, membrane potential collapse, and excessive reactive oxygen species generation in R28&nbsp;cells. Suppressing miRNA-122-5p alleviated these injuries. Dual-luciferase assays confirmed that miRNA-122-5p directly targets PARK7, thereby post-transcriptionally repressing DJ-1 expression and compromising mitochondrial resilience. These findings establish miRNA-122-5p as a critical upstream regulator of DJ-1-mediated antioxidant defense. By aggravating mitochondrial oxidative stress, it contributes to RGC vulnerability in DR. Targeted modulation of miRNA-122-5p may offer a novel therapeutic approach to preserve retinal neurons and counteract neurodegeneration in DR.\n  --- END ACTUAL ABSTRACT FOR 40759398 ---\n\n- ERROR: You cited ID: 40384765 for the quote: \"Serum pro-brain natriuretic peptide (BNP) is a 108-amino-acid prohormone that inhibits vascular endothelial growth factor (VEGF) secretion, protecting pericytes from cell death.\"\n  FACT: Strict Misquote Detected!

The purpose of this study was to investigate the correlation of serum pro-BNP with optical coherence tomography (OCT) indices in diabetic retinopathy. This cross-sectional study investigated 96 consecutive subjects aged between 40 and 65 years: controls n = 24, no diabetic retinopathy (NoDR) n = 24, non-proliferative diabetic retinopathy (NPDR) n = 24, and proliferative diabetic retinopathy (PDR) n = 24. Same-day analysis of blood samples for serum pro-BNP levels was performed and spectral-domain OCT (SD-OCT) was used to measure the following OCT indices: OCT angiography (OCTA) superficial vessel density (SVD), deep vessel density (DVD), and foveal avascular zone (FAZ); OCT retinal nerve fiber layer (RNFL); and OCT ganglion cell analysis (GCA). The mean serum pro-BNP levels for the control, NoDR, NPDR, and PDR groups were 14.07 \u00b1 11.51, 27.35 \u00b1 11.81, 280.44 \u00b1 106.13, and 122.33 \u00b1 43.66 pg/ml, respectively. The mean values of the various OCT parameters correlated with serum pro-BNP were OCTA SVD (r = - 0.360), OCTA DVD (r = 0.408), OCTA FAZ (r = 0.475), OCT RNFL (r = - 0.215) and OCT GCA (r = - 0.285; p&lt;0.001). The serum pro-BNP levels were higher in the NPDR group than in the NoDR group and much lower in the PDR group than in the NPDR group, reflecting a lowering of the protective barrier. These results correlated with the changes in various OCT indices.\n  --- END ACTUAL ABSTRACT FOR 40384765 ---\n\n- ERROR: You cited ID: 40216954 for the quote: \"CaMK2A knockdown or CREB phosphorylation inhibition attenuated HG-induced mitophagy, apoptosis, and neurotransmitter depletion.\"\n  FACT: Strict Misquote Detected!

The Ca2+/calmodulin-dependent protein kinase II alpha (CaMK2A) and cAMP response element-binding protein (CREB) signaling pathway has been implicated in various neurological disorders. However, its role in DR pathogenesis remains elusive. We established a DR mouse model by streptozotocin administration and performed histological, biochemical, and molecular analyses to investigate the involvement of CaMK2A/CREB signaling and its interplay with mitophagy. Additionally, we employed in vitro high-glucose (HG) treatment in primary mouse retinal ganglion cells to dissect the underlying mechanisms. Pharmacological and genetic modulations were utilized to target CaMK2A/CREB pathway and mitophagy. In the DR model, we observed retinal degeneration, increased apoptosis, and reduced neurotransmitter production, accompanied by enhanced mitophagy and activation of the CaMK2A/CREB pathway. HG induction in retinal ganglion cells recapitulated these findings, and autophagy inhibition partially rescued cell death but failed to suppress CaMK2A/CREB activation, suggesting mitophagy as a downstream consequence. CaMK2A knockdown or CREB phosphorylation inhibition attenuated HG-induced mitophagy, apoptosis, and neurotransmitter depletion, while CREB activation exacerbated these effects. CaMK2A silencing mitigated DR progression, oxidative stress, inflammation, and neuronal loss, akin to dopamine/carbidopa administration in DR mouse model. Our findings reveal the involvement of CaMK2A/CREB signaling activation and enhanced mitophagy in DR, suggesting these pathways may be therapeutically relevant targets for DR management.\n  --- END ACTUAL ABSTRACT FOR 40216954 ---\n\n- ERROR: You cited ID: 40180022 for the quote: \"Treatment with S-nitroso-N-acetyl penicillamine (SNAP), an NO donor, significantly downregulated TXNIP/NLRP3 inflammasome signaling in RMG, decreased RGC apoptosis.\"\n  FACT: Strict Misquote Detected!

This study aimed to elucidate whether nitric oxide (NO) can modulate the TXNIP/NLRP3 inflammasome pathway and mitigate retinal neurovascular unit (NVU) damage during early DR. In an in vitro co-culture system, silencing TXNIP or NLRP3 in retinal microglia (RMG) significantly upregulated glial cell-derived neurotrophic factor (GDNF) and downregulated inducible nitric oxide synthase (iNOS) expression in retinal ganglion cells (RGC). Moreover, it resulted in decreased iNOS and vascular endothelial growth factor A (VEGFA) levels and enhanced the expression of tight junction proteins (Occludin and ZO-1) in retinal microvascular endothelial cells (RMEC), while also reducing NO release and inhibiting RMEC tube formation. Treatment with S-nitroso-N-acetyl penicillamine (SNAP), an NO donor, significantly downregulated TXNIP/NLRP3 inflammasome signaling in RMG, decreased RGC apoptosis, and inhibited tube formation in RMEC. It also upregulated GDNF, suppressed iNOS in RGC, decreased VEGFA, and improved tight junction proteins in RMEC. Treatment with 1400W, an iNOS inhibitor, resulted in decreased NO concentration and increased IL-1\u03b2 levels in the co-culture supernatant, without significantly affecting iNOS expression in RGC or RMEC. In an early DR rat model, Electroretinogram (ERG), Optical Coherence Tomography (OCT), Fluorescein Angiography (FFA), Evans blue assays, Immunofluorescence staining, and TUNEL staining confirmed that sodium nitroprusside (SNP), NO donor administration mitigated retinal neural and vascular dysfunction, and preserved retinal NVU integrity. Concurrently, SNP treatment reduced IL-1\u03b2 expression and increased GDNF and Occludin levels in the early DR retina. Genetic Association Database (GAD) enrichment analysis and protein-protein interaction (PPI) network validation indicated that NO functions as a downstream mediator of the TXNIP/NLRP3 inflammasome pathway and exhibits a strong association with DR. These findings suggest that NO mediates negative feedback in the TXNIP/NLRP3 inflammasome pathway to exert protective effects against retinal NVU dysfunction in early DR, thereby offering potential therapeutic strategies for early intervention in DR.\n  --- END ACTUAL ABSTRACT FOR 40180022 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma\" (Source: 42456876)\n- \"SPG302 treatment effectively preserved retinal integrity by reversing these changes.\" (Source: 42456876)\n- \"Within the RNVU, calcium ions coordinate neurotransmission, glial activation, vascular tone, and blood-retinal barrier maintenance, and calcium dysregulation is emerging as a unifying pathogenic hub across these conditions.\" (Source: 42352232)\n- \"We found that retinal neurodegeneration may precede microvascular leakage in diabetic retinas.\" (Source: 42041557)\n- \"Our results provide the first evidence that intravitreal injection of human WFS1 has significant neuroprotective effects on retinal ganglion cells and their axons and slows the loss of visual acuity.\" (Source: 41998758)\n- \"The rat experimental study validated this assumption and indicated a protective effect for betanin on rat retinas as shown by routine hematoxylin and eosin staining (retinal thickness and ganglion cell count)\" (Source: 41539543)\n- \"GCC parameter is useful tool for diagnosis of Glaucoma.

SPG302, a pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and demonstrates neuroprotective potential in both diabetic and glaucomatous models by mitigating inner retinal damage and preserving visual function.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm of diabetic retinopathy has shifted from a primarily microvascular perspective to a neurovascular degenerative disorder where retinal ganglion cell (RGC) integrity and synaptic stability serve as critical therapeutic targets. The provided literature establishes that DRN manifests as inner retinal degeneration with a loss of ganglion cells and a reduction in synaptic markers, such as PSD95 and synaptophysin. SPG302 stands out as a \"synaptogenic small molecule\" that demonstrates broad applicability across neurodegenerative conditions, including glaucoma and diabetes, by reversing synaptic loss. By promoting synaptogenesis, SPG302 preserves retinal structural integrity and functional output as measured by electroretinography. This approach is aligned with the broader understanding that restoring synaptic architecture and metabolic homeostasis is requisite for preventing the irreversible vision loss associated with diabetic and glaucomatous neurodegeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Neurodegeneration, particularly RGC loss and synaptic impairment, often precedes clinical microvascular symptoms in diabetic retinopathy.\n*   SPG302 acts as a synaptogenic agent, capable of mitigating retinal injury across different disease etiologies, including glaucoma.\n*   The synaptic dysfunction in diabetes and glaucoma involves common molecular pathways, such as the modulation of postsynaptic density (PSD) proteins.\n*   Exosomes derived from specific physiological states (like hibernation) have been identified as potential mediators of intrinsic neuroprotection, suggesting novel intercellular signaling pathways.\n*   The use of GLP-1 receptor agonists and traditional Chinese medicines (e.g., Danshen, Ginsenoside Rg1) provides alternative, multi-target strategies for mitigating neuroinflammation in the retina.\n*   Calcium dysregulation acts as a \"unifying pathogenic hub\" for neurovascular unit dysfunction across multiple neurodegenerative diseases.\n*   Targeting the autophagy-lysosomal pathway (e.g., via the SNAI1-LAMP3 axis) represents an emerging therapeutic direction to preserve RPE and retinal neurons.\n*   Metabolic variability (e.g., glucose flux and uric acid levels) significantly influences the rate of ganglion cell thinning in diabetic patients without retinopathy.\n*   Advanced multimodal imaging (e.g., SS-OCTA) allows for the early detection of neurovascular uncoupling, which serves as a biomarker for disease progression.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment."

Within the RNVU, calcium ions coordinate neurotransmission, glial activation, vascular tone, and blood-retinal barrier maintenance, and calcium dysregulation is emerging as a unifying pathogenic hub across these conditions. Although upstream triggers differ, including mechanical stress in glaucoma, hyperglycemia in DR, oxidative damage in AMD, ischemic energy failure in RIR, and amyloid-\u03b2-driven endoplasmic reticulum stress in AD, all converge on disruption of intracellular calcium homeostasis, producing shared downstream consequences including excitotoxic injury of retinal ganglion cells (RGCs), M\u00fcller cell reactive gliosis, and pericyte hypercontraction. Broad-spectrum calcium channel blockade has shown limited clinical success, underscoring the need for cell-type-specific and pathway-selective approaches. This review therefore catalogs key interventional nodes, including transient receptor potential (TRP) channel antagonists, T-type calcium channel inhibitors, calcium/calmodulin-dependent protein kinase II (CaMKII) suppressors, and mitochondrial permeability transition pore (mPTP) inhibitors, and discusses how precision targeting of these pathways may restore RNVU homeostasis and open a therapeutic window into central nervous system (CNS) degenerative disorders."

Acarbose (ACA), an \u03b1-glucosidase inhibitor widely used for diabetes, has recently been recognized for its dual regulatory potential on immune metabolism and aging-associated neurodegeneration. Here, we demonstrate that intravitreal ACA administration attenuates retinal inflammation and improves RGCs survival following IR injury. Single-cell RNA sequencing revealed extensive inflammatory activation and metabolic reprogramming across the retina, characterized by enhanced nicotinamide adenine dinucleotide (NAD) catabolism, particularly in microglia. ACA treatment was associated with reversal of these alterations, replenished NAD levels, and restored mitochondrial integrity. Integrative proteomic and biochemical analyses identified pyruvate kinase, muscle-type 2 (Pkm2) as a candidate regulatory node affected by ACA. Intravitreal delivery of siPkm2 partially protected against IR injury, and co-administration with ACA produced an additive trend in neuroprotection. Mechanistically, ACA upregulated sirtuin 1 (Sirt1) and reduced Pkm2 acetylation at lysine 270 (K270), which was linked to pro-inflammatory microglial activation. Structure-based virtual screening further identified HY-113082, a small molecule targeting Pkm2-K270, which synergized with ACA to suppress inflammation and enhance retinal protection. Moreover, Pkm2fl/flCx3cr1-Cre mice conferred partial resistance to IR injury, but blunted the additional benefit of HY-113082 when combined with ACA, consistent with on-target engagement. Our findings support that ACA exerts retinal protection through the Sirt1-Pkm2-NAD axis, suggesting a metabolic checkpoint that integrates immune and mitochondrial regulation. This study provides mechanistic insight into ACA's dual immunometabolic and neuroprotective actions, holding promise for therapeutic insights into neuroinflammation."

In this study, we investigated the protective effects of norrin against hyperglycemia-induced retinal neurodegeneration and elucidated its underlying molecular mechanisms in diabetic mice. We found that retinal neurodegeneration may precede microvascular leakage in diabetic retinas. Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Intravitreal supplementation of norrin markedly attenuated hyperglycemia-induced neurodegenerative processes, leading to retinal ganglion cell (RGC) apoptosis, including oxidative stress, inflammation, and neuropathological alterations such as reactive gliosis, glutamate excitotoxicity, and synaptic dysfunction. Norrin also reduced hyperglycemia-induced microvascular leakage and RGC apoptosis by normalizing vascular endothelial growth factor (VEGF) overexpression and restoring pigment epithelium-derived factor (PEDF) levels. Notably, PEDF upregulated by norrin effectively suppressed neurodegenerative processes induced by hyperglycemia or VEGF, thereby preserving RGC function. These findings identify norrin as a critical modulator of hyperglycemia-induced retinal neurodegeneration through restoration of the VEGF-PEDF balance. Our results highlight norrin as a potential therapeutic target for early neurodegenerative changes in diabetic retinopathy."

This study sought to determine the effects of pelargonidin on extracellular matrix (ECM) modulation and the inhibition of transforming growth factor-\u03b2 (TGF-\u03b2) and Janus Kinase 2/Signal Transducer and Activator of Transcription 3 (JAK2/STAT3) pathway in retinal ganglion cells of streptozotocin-induced diabetic rats. Male Sprague-Dawley rats (180-200 g) were rendered diabetic by intraperitoneal administration of streptozotocin (STZ). The rats were divided into 5 groups: control, diabetic model (STZ), STZ + low dose pelargonidin (12.5 mg kg-1 per day), STZ + medium dose pelargonidin (25 mg kg-1 per day) and STZ + high dose pelargonidin (50 mg kg-1 per day). IOP was monitored using a tonometer. Whole-mount retinal immunofluorescence staining using RNA-binding protein with multiple splicing (RBPMS) was performed to assess retinal ganglion cell (RGC) density. Protein expression levels of apoptotic markers, ECM components, and TGF-\u03b2 and JAK2/STAT3 signalling pathways were evaluated by Western blotting. Pelargonidin treatment dose-dependently reduced the elevated IOP. Importantly, immunofluorescence analysis revealed a marked dose-dependent preservation of retinal ganglion cell (RGC) density: STZ-induced RGC loss was significantly reversed by pelargonidin, with the highest dose restoring RGC density to near-control or higher levels in both the central and peripheral retina. This was achieved via modulation of apoptosis-related proteins through the upregulation of Bcl-xL, Bcl-2, and downregulation of Bad, Bax and cleaved caspase-3. Furthermore, pelargonidin modulated ECM remodelling protein expression in the RGC layer. In particular, TGF-\u03b22/Smad2/3 signalling was downregulated, and the JAK2/STAT3 pathway was upregulated. By reducing IOP, preserving RGC density, modulating ECM deposition, inhibiting TGF-\u03b2 and upregulating the JAK2/STAT3 pathway, pelargonidin exerts protective effects against diabetic retinal injury. The results of this study further confirm the pharmacological potential of pelargonidin as a therapeutic agent for diabetic retinopathy."

This review examines the complex structural, functional, and molecular differences in NMJs that innervate fast- and slow-twitch skeletal muscle fibers. Fast-twitch fibers, optimized for rapid and powerful contractions, possess elaborate NMJs with deep folds, high neurotransmitter turnover, and greater vulnerability to synaptic fatigue and degeneration. In contrast, slow-twitch fiber NMJs exhibit simpler but more stable architectures that support sustained, fatigue-resistant activity. These differences are not fixed but subject to activity-dependent plasticity and pathological remodeling. Chronic stimulation, injury, and aging influence NMJ morphology, with fast-twitch junctions more prone to degeneration in conditions such as ALS, myasthenia gravis, and diabetic neuropathy. Slow-twitch NMJs often resist early deterioration due to superior trophic support, metabolic stability, and more robust expression of synaptic organizers, such as agrin and PGC-1\u03b1. Several key signaling pathways, including agrin-MuSK-LRP4, Wnt/\u03b2-catenin, and neuregulin/ErbB, govern NMJ maintenance with fiber-type-specific nuances. These insights underscore the importance of tailoring therapeutic strategies to the muscle fiber phenotype. Gene therapies, neuromuscular electrical stimulation, and biomaterial scaffolds are emerging as promising modalities for preserving or restoring NMJ integrity, especially in fast-twitch fibers at higher risk of degeneration. Understanding fiber-type-specific NMJ biology enhances our understanding of motor control, muscle aging, and neuromuscular disease progression, and it opens pathways for precision therapeutics that target vulnerable synapses with structural and functional specificity. This review introduces a novel perspective by emphasizing fiber-type-specific NMJ differences and their implications for targeted therapies."

Evidence suggests that additional vascular and neurodegenerative mechanisms may be involved. This study aimed to characterise the thickness of the Ganglion Cell Complex (GCC) and investigate the Choroidal Vascularity Index (CVI) in patients with different patterns of therapeutic response to AVEGF DME. This cross-sectional study included 27 diabetic patients into 3 different groups based on their response to AVEGF therapy: control group, responder DME group, and persistent DME group. The study's approach to vascular and neurodegenerative imaging biomarkers involved three steps: (1) Automatic quantification of GCC thickness, with manual correction when necessary; (2) Semi-automatic measurement of choroidal thickness; and (3) Analysis of choroidal area and choroidal luminal area using ImageJ software to calculate the CVI. In the overall characterization of the sample, a significant difference was observed only in the Best Corrected Visual Acuity (BCVA). There was a significant difference in Average Retinal Thickness (1\u00a0mm, 3\u00a0mm, and 6\u00a0mm) between the 3 groups and in GCC thickness at 1\u00a0mm. BCVA was negatively correlated with mean retinal thickness, while CVI showed a potential positive correlation with BCVA. While demographic and general clinical characteristics showed minimal differences across the groups, important differences in GCC and choroidal characteristics were observed. GCC (1\u00a0mm) may be interesting to explore in predicting visual outcomes after treatment, and CVI may impact visual gain."

Studies, including our own, demonstrate that SRR is linked to a complication of diabetes, diabetic retinopathy (DR), and deletion of Srr protects diabetic animals from developing retinopathy. We investigate the feasibility and mechanisms of SRR inhibition as a strategy to prevent DR. SRR proteins in the retinas of db/db mice were approximately 50\u00a0% higher than C57BLKS/J wild-type (WT) mice, while D-serine levels in the aqueous humor were more than two-fold higher. Oral gavage of l-aspartic acid \u03b2-hydroxamate (L-ABH) improved b-wave amplitudes in electroretinogram recordings under both photopic and scotopic conditions. It also protected the inner retina in db/db mice by reducing the loss of retinal ganglion cells, endothelial cells, and pericytes, as well as decreasing the activation of M\u00fcller cells. In high glucose and hypoxia, interleukin-1 and interleukin-18 mRNA levels were lower in Srr-deleted M\u00fcller cell cultures than in WT cultures. Intravitreal injection of L-ABH mitigated glutamate-induced neurotoxicity in the retina. Systemically, L-ABH maintained euglycemia and improved glucose tolerance in db/db mice by inhibiting liver gluconeogenesis through restricting the expansion of pancreatic islet \u03b1-cells. Altogether, our results demonstrate that SRR inhibition prevents retinopathy in diabetic animals by blocking excitotoxicity and M\u00fcller cell-mediated inflammation in the retina, while also maintaining glucose homeostasis. This is the first demonstration that pharmacological blockade of SRR improves retinopathy and normalizes glucose levels in a type 2 diabetes model."

Prospective observational cohort study. T2DM patients without clinical retinopathy at baseline and after a 2-year follow-up, along with age- and sex-matched healthy controls, were recruited from the community in Guangzhou, China. Measurements of macular GCIPLT, retinal thickness (RT), and SCP vessel density were conducted at baseline and at the 2-year follow-up.

Significant reductions in GCIPLT and GCIPLT/RT occurred only in the non-DR group, with GCIPLT decreasing by -0.229 \u00b5m/y (95% CI = -0.313 to -0.144; P < .001) and 0.324 % (95% CI = 0.444 to 0.204; P < .001), approximately 5-fold faster than in the control group.

We determined the expression of HuD and alpha-crystallin A (CRYAA) in the retinal ganglion cell layer.

Silencing and overexpression of HuD positively regulated the expressions of Cryaa mRNA and protein. We demonstrated that the increase in inflammatory cytokines such as TNF\u03b1, IL-1\u03b2, and IL-6 in R-28 cells under hyperglycemic conditions was a result of both CRYAA and HuD levels.

DJ-1 (PARK7) acts as a crucial antioxidant defense mechanism, stabilizing mitochondrial structure and redox balance. However, its expression is dramatically suppressed under diabetic conditions, and the upstream regulatory mechanisms remain incompletely characterized. Growing evidence from epigenetic research implicates microRNAs (miRNAs) as important players in the molecular pathways underlying DR progression. Among these, miRNA-122-5p has drawn increasing attention due to its aberrant activity under diabetic stress and its putative interaction with PARK7. In this study, we employed a streptozotocin-induced type 1 diabetes mouse model and glucose-stimulated R28\u00a0cells to explore the contribution of miRNA-122-5p to mitochondrial damage, oxidative stress, and RGC injury. In diabetic mice, we observed significant oxidative imbalance, increased apoptotic activity, RGC loss, and diminished retinal function. MiRNA profiling identified miRNA-122-5p as the most upregulated among candidate miRNAs. Inhibition of miRNA-122-5p attenuated these pathological changes and preserved both cellular integrity and visual function. In vitro, high glucose triggered mitochondrial fragmentation, membrane potential collapse, and excessive reactive oxygen species generation in R28\u00a0cells. Suppressing miRNA-122-5p alleviated these injuries. Dual-luciferase assays confirmed that miRNA-122-5p directly targets PARK7, thereby post-transcriptionally repressing DJ-1 expression and compromising mitochondrial resilience. These findings establish miRNA-122-5p as a critical upstream regulator of DJ-1-mediated antioxidant defense. By aggravating mitochondrial oxidative stress, it contributes to RGC vulnerability in DR. Targeted modulation of miRNA-122-5p may offer a novel therapeutic approach to preserve retinal neurons and counteract neurodegeneration in DR."

Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months.

Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy."

This study investigated whether L-serine supplementation could attenuate DN through dose-dependent metabolic and neuroprotective mechanisms in a high-fat diet (HFD) plus streptozotocin (STZ)-induced diabetic rat model. Male Wistar rats (n = 8 per group) were allocated to five groups: normal control (NC), diabetic control (DC), pioglitazone (PIO; 1.5 mg/kg/day), low-dose L-serine (S1; 200 mg/kg/day), and high-dose L-serine (S2; 400 mg/kg/day). After 60 days of oral gavage, behavioural testing, glucose and insulin profiling, HOMA-IR calculation, brain histopathology, nerve growth factor (NGF) immunohistochemistry, and LC-MS/MS-based proteomic analysis of cerebral tissue were performed. Diabetic rats exhibited marked hyperglycaemia (355.33 \u00b1 4.72 mg/dL), hyperinsulinaemia, severe insulin resistance (HOMA-IR 16.8 \u00b1 3.2; a 14-fold increase), impaired thermal nociception, motor dysfunction, and pronounced neuronal degeneration. L-serine supplementation significantly improved metabolic status: S1 reduced HOMA-IR by 77.4% and S2 by 87.5% relative to diabetic controls (p < 0.001). High-dose L-serine produced greater improvements in thermal sensitivity, motor coordination (rotarod latency 26.67 \u00b1 1.52 s vs. 16.1 \u00b1 0.85 s in DC; p < 0.05), and NGF expression (8.6-fold increase vs. DC). Histopathology confirmed attenuation of neuronal injury and gliosis in both treatment groups. Exploratory, group-level proteomic profiling identified dose-specific molecular signatures: S1 was predominantly associated with carbohydrate, lipid, and biosynthetic pathways, whereas S2 was associated with synaptic, neurotransmission-related, and proteostasis pathways. Within the constraints of an exploratory design-group-level pooled proteomics, analysis of cerebral rather than peripheral-nerve tissue, and only two doses-these findings indicate that L-serine attenuates the metabolic and behavioural features of experimental diabetic neuropathy and generates the testable hypothesis of dose-dependent neuro-metabolic remodelling. The proteomic signatures are hypothesis-generating and require orthogonal validation before any mechanistic or translational inference can be drawn."

Two independent reviewers performed screening, extraction, and the revised Cochrane Risk of Bias tool version 2.0 (RoB 2.0). Random-effects meta-analyses were conducted using the mean differences (MD) with 95% confidence intervals (CI). Five RCTs (n\u2009=\u2009660) met the criteria. Tocotrienol-rich vitamin E increased sural sensory nerve-conduction velocity (NCV) by 1.77\u00a0m s\u207b\u00b9 (0.80-2.74) and median sensory NCV by 1.53\u00a0m s\u207b\u00b9 (0.44-2.63); tibial motor NCV rose 1.47\u00a0m s\u207b\u00b9 (0.36-2.58) versus placebo.

The absence of glycemic effects indicates neuroprotection independent of glucose control, positioning vitamin E as a potential adjunct-not substitute-to antidiabetic therapy. Heterogeneity in isoform, dose, and treatment duration (\u2264\u200912 months) and modest sample sizes limit certainty. Larger, longer trials incorporating functional outcomes (pain, gait, and quality of life) are required."

SPG302, a pegylated benzothiazole derivative, demonstrates efficacy in promoting glutamatergic synaptogenesis and preserving retinal integrity. This evaluation synthesizes current literature on the impact of diabetes on RGCs, the role of synaptic loss in disease progression, and the therapeutic potential of SPG302 and similar neuroprotective agents.\n\n### [INTRODUCTION & JUSTIFICATION]\nDiabetic retinal neuropathy (DRN) is an early hallmark of diabetic retinopathy that frequently occurs prior to visible microvasculopathy. The pathology involves the loss of RGCs, impaired RGC function, and a significant decrease in inner retinal synaptic markers. Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function. Because loss of glutamatergic synapses contributes to neuronal atrophy, therapeutic interventions targeting synaptic restoration offer a new point for disease mitigation. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma. Studies demonstrate that SPG302 treatment effectively preserved retinal integrity by reversing these changes. \n\nIn both glaucoma and diabetes, RGC vulnerability is driven by metabolic and neurodegenerative processes. Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. In glaucomatous neurodegeneration, synaptic abnormalities are key, and SPG302 treatment effectively preserved synaptic integrity by reversing these changes. Further neuroprotective strategies include the use of norrin to restore PEDF levels, where Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Additionally, mitochondrial homeostasis is critical, as evidenced by studies showing sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   DRN often presents as a neurodegenerative disease manifesting before clinical microvascular damage is visible.\n*   SPG302 promotes glutamatergic synaptogenesis, offering a potential mechanism to restore synaptic connections that are lost early in the disease process.\n*   Mitochondrial transplantation and mitophagy regulation represent emerging frontiers in preserving RGC viability.\n*   Norrin, a protein secreted by M\u00fcller cells, is crucial for Wnt signaling and retinal capillary formation, and its downregulation is a key pathological event in diabetes.\n*   Neuroprotective effects of therapeutics such as fenofibrate, pelargonidin, and UAB126-MP occur via diverse signaling pathways (e.g., RXR agonism) distinct from conventional pressure-lowering.\n*   The integrity of the neurovascular unit is fundamentally tied to synaptic communication, which remains dysregulated following RGC injury.\n*   Emerging gene therapies, such as WFS1 delivery, show promise for genetic-based optic neuropathies.\n*   Advanced imaging and machine learning (e.g., 2.5D CFF module) are improving the precision of diagnostic markers like the Ganglion Cell Complex (GCC).\n*   Dietary and natural compounds, including eucalyptol and L-serine, show evidence for mitigating metabolic features of diabetic neuropathy.\n*   The relationship between systemic metabolic health and retinal neurodegeneration suggests that retinal assessment could serve as a systemic prognostic tool.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function, decreased inner retina synaptic markers, and increased reactive gliosis and cell death. Loss of glutamatergic synapses in the retina precedes, and may contribute to, overt neuron loss in DR, thus offering a potential new point for therapeutic intervention. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma, another leading cause of blindness associated with early synapse loss in the retina. To evaluate potential protective effects of SPG302 in DR, db/db mice (a diabetic mouse model with an inactivation mutation in the leptin receptor) were treated with intraperitoneal SPG302 or vehicle for 8 weeks (16-24 weeks of age). Db/+ mice served as an additional control. Db/db mice demonstrated weight gain, hyperglycemia, insulin intolerance, and glucose intolerance, while db/+ mice did not. SPG302 treatment did not change these metabolic parameters. Following treatment, GC function was assessed using electroretinography (ERG). Mice were then euthanized for quantification of retinal GCs, synaptic markers, glial markers, and markers of cell death using immunofluorescence staining and Western blot methods. Db/db mice demonstrated significant loss of GC ERG signal and GC cell number, decreased PSD95 and synaptophysin expression indicative of synapse loss, as well as increased reactive gliosis and expression of cell death markers such as pBAD and BAX. SPG302 treatment effectively preserved retinal integrity by reversing these changes. Thus, SPG302 has therapeutic potential for protecting the inner retina and mitigating DRN in diabetes.\n\nID: 42398881\nTitle: Mitochondrial Dysfunction and Diabetic Retinopathy: Research Progress from Pathogenic Mechanisms to Therapeutic Targets.\nAbstract: Diabetic retinopathy (DR) is one of the most common microvascular complications of diabetes mellitus (DM) and remains a major cause of visual impairment and blindness in adults. Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment.\n\nID: 42352232\nTitle: Calcium at the Helm: Mechanisms and Therapeutic Targets in the Retinal Neurovascular Unit.\nAbstract: Retinal neurovascular unit (RNVU) dysfunction underlies major blinding and neurodegenerative conditions including glaucoma, diabetic retinopathy (DR), age-related macular degeneration (AMD), retinal ischemia-reperfusion (RIR) injury, and Alzheimer's disease (AD)-associated retinopathy. Within the RNVU, calcium ions coordinate neurotransmission, glial activation, vascular tone, and blood-retinal barrier maintenance, and calcium dysregulation is emerging as a unifying pathogenic hub across these conditions. Although upstream triggers differ, including mechanical stress in glaucoma, hyperglycemia in DR, oxidative damage in AMD, ischemic energy failure in RIR, and amyloid-\u03b2-driven endoplasmic reticulum stress in AD, all converge on disruption of intracellular calcium homeostasis, producing shared downstream consequences including excitotoxic injury of retinal ganglion cells (RGCs), M\u00fcller cell reactive gliosis, and pericyte hypercontraction. Broad-spectrum calcium channel blockade has shown limited clinical success, underscoring the need for cell-type-specific and pathway-selective approaches. This review therefore catalogs key interventional nodes, including transient receptor potential (TRP) channel antagonists, T-type calcium channel inhibitors, calcium/calmodulin-dependent protein kinase II (CaMKII) suppressors, and mitochondrial permeability transition pore (mPTP) inhibitors, and discusses how precision targeting of these pathways may restore RNVU homeostasis and open a therapeutic window into central nervous system (CNS) degenerative disorders.\n\nID: 42228681\nTitle: Stem Cell Based Interventions for Retinal Ganglion Cell Protection and Regeneration in Glaucoma: A Review of Current Evidence and Future Directions.\nAbstract: Glaucoma is one of the leading causes of irreversible blindness, due to the ongoing loss of retinal ganglion cells (RGCs) and degeneration of the axons which form a major part of the retino-cortical pathway. Although there are some therapies available which primarily ameliorate the intraocular pressure (IOP), loss of sight often continues and thus illustrate the need for therapies which address the degeneration of the nervous system. Stem cell interventions have the unique potential to assist with the preservation and restoration of dysfunctional RGCs via direct cellular replacement, differential neuroprotection, and stimulating endogenous repair mechanisms. The focus of this review is on the most contemporary innovations which utilize stem cells to preserve and regenerate RGCs, which are vitally important for sight. The review addresses some of the newer cell source and cell prep technologies, particularly those using disorganized retinal microenvironment cell preps. Retinal microenvironment cell preps have resulted in some novel microenvironment cells designed to sequester stem cell grafts, to improve stem cell microenvironment cell preps, for augmenting microenvironment cell preps. Some of the major challenges such as reconstructing and integrating the lost retino-tectal and retino-collateral synapses in the visual pathway and the axonal outgrowth to and targeting appropriate central visual synaptic areas. Some major challenges are safety, RGC immunochemistry and cell type diversity, and scalable cell prep technologies. This review encapsulates how stem cell biology, along with other technologies like gene editing and tissue engineering, are forming the basis for developing first-of-its-kind regenerative therapies to restore vision in glaucoma patients, based on recent pre-clinical studies and ongoing early-phase clinical trials.\n\nID: 42196293\nTitle: The Metabolic Architecture of Glaucoma: A Unified Framework of Cofactor Failure and Kynurenine Dysregulation.\nAbstract: Glaucoma remains a primary cause of blindness, yet its pathogenesis often extends beyond intraocular pressure (IOP). This review integrates four converging lines of metabolic evidence-aqueous humor (AH) metabolomics, kynurenine pathway (KP) activity, tetrahydrobiopterin (H4BIP) biology, and NAD/one-carbon dysfunction-into a testable framework for retinal ganglion cell vulnerability. By utilizing a systematic AH metabolomics atlas covering glaucoma, pseudoexfoliation, and diabetes on a standardized HILIC-LC-HRMS platform, we demonstrate that, while aromatic amino acid elevations are non-specific markers, kynurenine monooxygenase (KMO) upregulation is a condition-specific glaucoma signature. These local findings are corroborated by systemic evidence: POAG patients exhibit significant folic acid deficiency (p = 0.007) and elevated alpha-1-antitrypsin (AAT). Critically, AAT correlates inversely with both serum folate (rs = -0.485, p < 0.001) and retinal nerve fiber layer thickness (rs = -0.386, p = 0.017), providing the first in-patient evidence linking systemic inflammation to structural optic nerve damage. We conclude that KMO serves as a critical enzymatic node linking tryptophan metabolism, H4BIP availability, and NAD synthesis. These results characterize glaucoma as a disease of progressive cofactor failure and define a research agenda for multimodal metabolic neuroprotection.\n\nID: 42103933\nTitle: Loss of mitochondrial DNA helicase in retinal macroglia drives neovascular retinopathy.\nAbstract: Retinopathy is a common symptom in mitochondrial diseases, and a leading cause of blindness in working-age individuals, often arising as a consequence of diabetes. Here, we demonstrate that postnatal loss of the replicative helicase of mitochondrial DNA in the astrocytes and M\u00fcller glia induces neovascular retinopathy. In these retinas, the macroglia show pathological reactivation, leading to hallmark features of neovascularization with blood-retina-barrier leakage, secondary microgliosis, and complement cascade activation. Similar reactivation of astrocytes in the cerebral cortex does not compromise vascular integrity, indicating tissue-specific roles of mitochondrial metabolism in macroglia for vascular homeostasis. Three secreted angiogenic factors-Fgf2, Pgf, and Lcn2-known to contribute to diabetic retinopathy, were induced. Spike recordings of the most sensitive retinal ganglion cells revealed normal rod function and intact retinal coding. These findings highlight the critical role of glial mitochondrial metabolism in neovascular retinopathy, with important implications for therapy development for mitochondrial and common forms of vision loss.\n\nID: 42069589\nTitle: Acarbose modulates microglial Pkm2 acetylation to reshape immunometabolism and preserve retinal neurons after ischemia-reperfusion.\nAbstract: Retinal ischemia-reperfusion (IR) elicits microglia-driven neuroinflammation and mitochondrial failure that led to retinal ganglion cell (RGCs) loss, yet effective disease-modifying therapies remain limited. Acarbose (ACA), an \u03b1-glucosidase inhibitor widely used for diabetes, has recently been recognized for its dual regulatory potential on immune metabolism and aging-associated neurodegeneration. Here, we demonstrate that intravitreal ACA administration attenuates retinal inflammation and improves RGCs survival following IR injury. Single-cell RNA sequencing revealed extensive inflammatory activation and metabolic reprogramming across the retina, characterized by enhanced nicotinamide adenine dinucleotide (NAD) catabolism, particularly in microglia. ACA treatment was associated with reversal of these alterations, replenished NAD levels, and restored mitochondrial integrity. Integrative proteomic and biochemical analyses identified pyruvate kinase, muscle-type 2 (Pkm2) as a candidate regulatory node affected by ACA. Intravitreal delivery of siPkm2 partially protected against IR injury, and co-administration with ACA produced an additive trend in neuroprotection. Mechanistically, ACA upregulated sirtuin 1 (Sirt1) and reduced Pkm2 acetylation at lysine 270 (K270), which was linked to pro-inflammatory microglial activation. Structure-based virtual screening further identified HY-113082, a small molecule targeting Pkm2-K270, which synergized with ACA to suppress inflammation and enhance retinal protection. Moreover, Pkm2fl/flCx3cr1-Cre mice conferred partial resistance to IR injury, but blunted the additional benefit of HY-113082 when combined with ACA, consistent with on-target engagement. Our findings support that ACA exerts retinal protection through the Sirt1-Pkm2-NAD axis, suggesting a metabolic checkpoint that integrates immune and mitochondrial regulation. This study provides mechanistic insight into ACA's dual immunometabolic and neuroprotective actions, holding promise for therapeutic insights into neuroinflammation.\n\nID: 42041557\nTitle: Norrin Ameliorates Retinal Ganglion Cell Apoptosis by Normalizing VEGF and PEDF Dysregulation in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy is increasingly recognized as a neurovascular disorder rather than a purely vascular disease; however, therapeutic strategies targeting retinal neurodegeneration remain limited. In this study, we investigated the protective effects of norrin against hyperglycemia-induced retinal neurodegeneration and elucidated its underlying molecular mechanisms in diabetic mice. We found that retinal neurodegeneration may precede microvascular leakage in diabetic retinas. Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Intravitreal supplementation of norrin markedly attenuated hyperglycemia-induced neurodegenerative processes, leading to retinal ganglion cell (RGC) apoptosis, including oxidative stress, inflammation, and neuropathological alterations such as reactive gliosis, glutamate excitotoxicity, and synaptic dysfunction. Norrin also reduced hyperglycemia-induced microvascular leakage and RGC apoptosis by normalizing vascular endothelial growth factor (VEGF) overexpression and restoring pigment epithelium-derived factor (PEDF) levels. Notably, PEDF upregulated by norrin effectively suppressed neurodegenerative processes induced by hyperglycemia or VEGF, thereby preserving RGC function. These findings identify norrin as a critical modulator of hyperglycemia-induced retinal neurodegeneration through restoration of the VEGF-PEDF balance. Our results highlight norrin as a potential therapeutic target for early neurodegenerative changes in diabetic retinopathy.\n\nID: 41998758\nTitle: WFS1 gene delivery rescues visual function in a mouse model of Wolfram syndrome.\nAbstract: Wolfram syndrome is a rare childhood neurodegenerative disease characterized by diabetes followed by severe and rapid optic atrophy leading to blindness before the age of 20. Patients often develop other symptoms, such as deafness and neurological dysfunction. Wolfram syndrome is caused by mutations in the WFS1 gene, which encodes wolframin protein. Despite decades of intensive research, the complex mechanisms of optic neuropathy are not fully understood, and there are currently no therapies to prevent vision loss in Wolfram patients. Here, we showed that the Wfs1 knockout mice produced by the Estonian group, in which exon 8 of the Wfs1 gene was disrupted, exhibit a progressive loss of visual acuity, optic disc pallor and severe optic nerve damage. We tested the efficiency of gene therapy using AAV2 to deliver human WFS1 to retinal ganglion cells in Wfs1 knockout mice. Our results provide the first evidence that intravitreal injection of human WFS1 has significant neuroprotective effects on retinal ganglion cells and their axons and slows the loss of visual acuity. These results demonstrate that WFS1 is able to provide both functional and structural protection to retinal ganglion cells in Wfs1 knockout mice and provide important evidence for the efficacy of WFS1 as a neuroprotective treatment for Wolfram syndrome. These results demonstrate the promising effects of gene therapy for Wolfram syndrome and encourage future research aimed at conducting clinical trials in patients.\n\nID: 41963265\nTitle: Pelargonidin protects retinal ganglion cells in a streptozotocin-induced diabetic rat model by reducing intraocular pressure, suppressing TGF-\u03b2 and activating JAK2/STAT3 signalling pathway.\nAbstract: Diabetic retinopathy (DR) is one of the primary causes of vision impairment, affecting individuals with diabetes, and is marked by the neurodegeneration of the retina along with increased intraocular pressure (IOP). This study sought to determine the effects of pelargonidin on extracellular matrix (ECM) modulation and the inhibition of transforming growth factor-\u03b2 (TGF-\u03b2) and Janus Kinase 2/Signal Transducer and Activator of Transcription 3 (JAK2/STAT3) pathway in retinal ganglion cells of streptozotocin-induced diabetic rats. Male Sprague-Dawley rats (180-200 g) were rendered diabetic by intraperitoneal administration of streptozotocin (STZ). The rats were divided into 5 groups: control, diabetic model (STZ), STZ + low dose pelargonidin (12.5 mg kg-1 per day), STZ + medium dose pelargonidin (25 mg kg-1 per day) and STZ + high dose pelargonidin (50 mg kg-1 per day). IOP was monitored using a tonometer. Whole-mount retinal immunofluorescence staining using RNA-binding protein with multiple splicing (RBPMS) was performed to assess retinal ganglion cell (RGC) density. Protein expression levels of apoptotic markers, ECM components, and TGF-\u03b2 and JAK2/STAT3 signalling pathways were evaluated by Western blotting. Pelargonidin treatment dose-dependently reduced the elevated IOP. Importantly, immunofluorescence analysis revealed a marked dose-dependent preservation of retinal ganglion cell (RGC) density: STZ-induced RGC loss was significantly reversed by pelargonidin, with the highest dose restoring RGC density to near-control or higher levels in both the central and peripheral retina. This was achieved via modulation of apoptosis-related proteins through the upregulation of Bcl-xL, Bcl-2, and downregulation of Bad, Bax and cleaved caspase-3. Furthermore, pelargonidin modulated ECM remodelling protein expression in the RGC layer. In particular, TGF-\u03b22/Smad2/3 signalling was downregulated, and the JAK2/STAT3 pathway was upregulated. By reducing IOP, preserving RGC density, modulating ECM deposition, inhibiting TGF-\u03b2 and upregulating the JAK2/STAT3 pathway, pelargonidin exerts protective effects against diabetic retinal injury. The results of this study further confirm the pharmacological potential of pelargonidin as a therapeutic agent for diabetic retinopathy.\n\nID: 41858631\nTitle: Compensatory responses to glaucoma pathology in the dorsolateral geniculate nucleus.\nAbstract: Glaucoma disrupts the conveyance of retinal signals to visual regions of the brain such as the dorsolateral geniculate nucleus (dLGN) due to degeneration of retinal ganglion cells (RGCs) and their axons. Although plasticity during development allows altered visual experience to modulate dLGN synapses and excitability, evidence for experience-dependent dLGN plasticity in adults is limited. However, glaucoma might trigger compensatory plasticity in adult dLGN, thereby compensating for diminished RGC synaptic drive. Here, we tested this theory using aged DBA/2J mice, which develop high intraocular pressure and glaucoma. In brain slice recordings, we found that diminished RGC inputs could drive robust action potential firing in dLGN relay neurons that was comparable to controls. This was accompanied by increased intrinsic excitability and decreased magnitude of sustained inhibitory currents from delta subunit-containing GABA receptors. These results implicate multiple cellular and synaptic mechanisms that support signaling despite the diminished RGC inputs in glaucoma.\n\nID: 41779109\nTitle: Association and Multimodal Model of Retinal Mid-Peripheral Capillary Free Zones with Structural and Functional Parameters in Diabetic Patients Without Clinical Retinopathy.\nAbstract: To investigate the association between mid-peripheral capillary free zones (CFZs) and retinal structural and functional metrics in diabetics without diabetic retinopathy (DR). This cross-sectional study included 45 eyes from 28 diabetics without DR and 46 eyes from 31 controls (mean age in both groups, 59 years). Macular optical coherence tomography (OCT) scans were acquired for retinal nerve fibre layer (RNFL) and ganglion cell layer thickness measurements. Thickness measurements were obtained using the Early Treatment of Diabetic Retinopathy Study grid. Retinal mid-peripheral CFZs were computed from OCT angiography images using custom MATLAB software. Retinal function was evaluated as a pilot exploratory objective using full-field flash electroretinography. Correlations between mid-peripheral CFZs and retinal structure and function were assessed using linear mixed-effect models, accounting for the association between eyes, while receiver operating characteristic curves were used to compare the multimodal models. Larger periarteriole CFZs were associated with thinner inner inferior RNFL thickness (\u03b2\u2009=\u2009-0.48, p\u2009=\u20090.03) in diabetics without DR. Functionally, there was no significant association between the mid-peripheral CFZs and ERG parameters (p\u2009>\u20090.05) in the no DR group; these findings should be interpreted with caution given the pilot nature of the functional data. The multimodal model of vascular and structural parameters had a modestly improved area under the curve (AUC) and specificity compared to the model of vascular parameters alone (AUC\u2009=\u20090.85 versus 0.83, specificity\u2009=\u20090.65 versus 0.54, respectively). These findings demonstrate that enlarged mid-peripheral periarteriole CFZs are associated with thinner RNFL in diabetics without clinical retinopathy. The multimodal model of vascular and structural metrics showed modestly improved diagnostic ability. This study shows early novel retinal vascular and neural associations in diabetics without clinical retinopathy and demonstrates the potential utility of a multimodal model for discriminating this group from healthy controls.\n\nID: 41750392\nTitle: Glutamate Metabotropic Receptors-Linked Postsynaptic Density Proteins: An Emergent Hub for Antipsychotics' Regulation of Synaptic Plasticity and Metaplasticity.\nAbstract: Glutamate metabotropic receptors (mGluRs) and their molecular partners at the postsynaptic density (PSD) represent a highly dynamic molecular hub that integrates multiple neurotransmitter signals and regulates synaptic plasticity and metaplasticity, which are putatively involved in the pathophysiology of psychiatric illnesses, including schizophrenia. Group I mGluRs (mGluR1 and mGluR5) interact with PSD adaptor and scaffolding proteins, such as Homer, Shank, Norbin, and PICK1, as well as intracellular downstream effectors, creating a molecular network that resembles a Lego-like structure, where modular protein interactions fine-tune glutamatergic transmission. Evidence from preclinical research indicates that dysregulation of mGluR expression and function, along with disrupted PSD protein expression, may contribute to the pathophysiology of schizophrenia by altering glutamatergic neurotransmission and synaptic stability. Antipsychotic mechanisms of action may involve, at least in part, the modulation of mGluR activity mediated through PSD proteins. Notably, novel agents that enhance spinogenesis by acting at the level of PSD proteins, such as SPG302, may open promising avenues for therapeutics aimed at restoring synaptic integrity. While Group I mGluRs dominate postsynaptic regulation, Group II (mGluR2/3) and III (mGluR4/6/7/8) receptors -primarily presynaptic- inhibit neurotransmitter release and plasticity, offering complementary therapeutic avenues. Emerging strategies, such as allosteric modulators of mGluRs, aim to rebalance synaptic signaling in treatment-resistant schizophrenia. This review synthesizes how PSD proteins and mGluRs interact in schizophrenia, exploring their potential as druggable targets for novel therapies.\n\nID: 41712748\nTitle: Disease modeling of myocilin mutation-dependent normal tension glaucoma: human retinal ganglion cell susceptibility to unfolded protein response and mTOR signaling.\nAbstract: Glaucoma represents a group of diseases where the unifying theme is the progressive degeneration of retinal ganglion cells (RGCs), causing irreversible vision loss. Mutations in the myocilin (MYOC) gene represent one of the most common genetic factors associated with primary open-angle glaucoma (POAG). However, the mechanism underlying MYOC mutation-associated POAG is poorly understood. Here, using human disease modeling of MYOC mutation (A445V)-dependent POAG, which is usually without ocular hypertension, we have tested a hypothesis that human RGCs (hRGCs) are the target of the mutant protein, making them vulnerable to degenerative changes. Examination of hRGCs generated from MYOCA445V POAG patient-specific induced pluripotent stem cells (iPSCs) revealed that their differentiation is adversely affected, compared to those generated from isogenic control iPSCs. Retinal ganglion cells regulatory and axon growth and guidance gene expression is decreased in patient-specific hRGCs vs isogenic controls. Consequently, the former display immature neurites and their ability to form synapses with the target cells and regenerate are compromised. Furthermore, they display immature networking physiology compared to isogenic controls. The pathological burden of the mutant protein is reflected in their preferential retention in the endoplasmic reticulum (ER) of patient-specific hRGCs, activating the unfolded protein response (UPR) toward mutation-associated developmental phenotype. Furthermore, we demonstrate that REDD1, a stress-induced factor, is a mechanistic link between the MYOCA445V-activated UPR axis and inhibited mTOR signaling, a critical regulator of RGC development and function. Ours is the first demonstration of MYOC mutation-dependent hRGC phenotype and posits a mechanism for hRGC susceptibility toward degeneration independent of ocular hypertension.\n\nID: 41606681\nTitle: Synaptic control of retinal ganglion cell survival and axon regeneration.\nAbstract: BACKGROUND: Injury to retinal ganglion cell (RGC) axons in neurodegenerative conditions like glaucoma leads to irreversible vision loss. A major therapeutic challenge is promoting RGC survival and axon regeneration. Canonical research focused on intrinsic neuronal growth capacity and the inhibitory central nervous system (CNS) environment, but overlooking the role of retinal synaptic communication. MAIN BODY: This review summarizes emerging evidence that retinal interneuron-to-RGC synaptic connections are both structurally and molecularly dysregulated following RGC axon injury. Such synaptic plasticity critically regulates RGC survival and regenerative capacity, at least partly by orchestrating intrinsic repair programs. We then address two central unresolved questions: first, what are the specific molecular pathways that alter this interneuron-to-RGC signaling after injury, and second, how do glial cells participate in this transsynaptic dysregulation. Finally, we evaluate the translational potential of these findings, including the identification of biomarkers and the development of novel neuroprotective strategies that target synaptic connections. CONCLUSION: Synaptic communication is a fundamental regulator of RGC fate after injury. Understanding synaptic dysregulation and the mechanisms involved is essential for developing new synapse-targeted strategies to monitor progression of neurodegenerative diseases and promote neural repair.\n\nID: 41554423\nTitle: Resveratrol alleviated diabetic retinal neuronal ferroptosis induced by high glucose through inhibiting HIF-1\u03b1 and HMOX1 pathway.\nAbstract: Diabetic retinopathy (DR) is a common complication of diabetes mellitus that can cause blindness and affect the life quality of patients. Diabetic retinal neurodegeneration (DRN) caused by high glucose might be the earlier pathological change preceding vascular injury. Resveratrol has been showed to have therapeutic effects on DRN but the mechanism remains unclear. Ferroptosis is a new form of regulated cell death and has been found to be involved in DRN. In this study, we found genetic relationship between resveratrol and ferroptosis in DRN pathogenesis using bioinformatics analysis and demonstrated HIF-1\u03b1 and HMOX1 as the hub genes. Our study established in vitro model of DRN in high-glucose cultured SH-SY5Y cells and found ferroptosis processes characterized of reactive oxygen species (ROS) accumulation and cellular mitochondrial damage along with upregulation of HIF-1\u03b1 and HMOX1. Application of resveratrol alleviated high glucose-induced ferroptosis phenotypes in SH-SY5Y cells through inhibiting HIF-1\u03b1 and HMOX1. We also confirmed ferroptosis process and RGC damage in diabetic (db/db) mouse model. The upregulation of HIF-1\u03b1 and HMOX1 was also found in diabetic mouse retina. By resveratrol gavage, RGC damage in diabetic (db/db) mouse model was alleviated and the expression level of HIF-1\u03b1 and HMOX1 in retina was decreased. Our study revealed the involvement of ferroptosis process in retinal neurodegeneration and might provide new insights into neuroprotective interventions in diabetic retinopathy.\n\nID: 41548740\nTitle: Fiber-type-specific architecture and pathophysiology of the neuromuscular junction.\nAbstract: The neuromuscular junction (NMJ) is a specialized synapse essential for translating neuronal signals into muscle contraction. This review examines the complex structural, functional, and molecular differences in NMJs that innervate fast- and slow-twitch skeletal muscle fibers. Fast-twitch fibers, optimized for rapid and powerful contractions, possess elaborate NMJs with deep folds, high neurotransmitter turnover, and greater vulnerability to synaptic fatigue and degeneration. In contrast, slow-twitch fiber NMJs exhibit simpler but more stable architectures that support sustained, fatigue-resistant activity. These differences are not fixed but subject to activity-dependent plasticity and pathological remodeling. Chronic stimulation, injury, and aging influence NMJ morphology, with fast-twitch junctions more prone to degeneration in conditions such as ALS, myasthenia gravis, and diabetic neuropathy. Slow-twitch NMJs often resist early deterioration due to superior trophic support, metabolic stability, and more robust expression of synaptic organizers, such as agrin and PGC-1\u03b1. Several key signaling pathways, including agrin-MuSK-LRP4, Wnt/\u03b2-catenin, and neuregulin/ErbB, govern NMJ maintenance with fiber-type-specific nuances. These insights underscore the importance of tailoring therapeutic strategies to the muscle fiber phenotype. Gene therapies, neuromuscular electrical stimulation, and biomaterial scaffolds are emerging as promising modalities for preserving or restoring NMJ integrity, especially in fast-twitch fibers at higher risk of degeneration. Understanding fiber-type-specific NMJ biology enhances our understanding of motor control, muscle aging, and neuromuscular disease progression, and it opens pathways for precision therapeutics that target vulnerable synapses with structural and functional specificity. This review introduces a novel perspective by emphasizing fiber-type-specific NMJ differences and their implications for targeted therapies.\n\nID: 41539543\nTitle: Betanin protects against diabetic retinal damage via the inhibition of NF-\u03baB/NLRP3/VEGF axis: Insights from network pharmacology and experimental studies.\nAbstract: Diabetic retinopathy (DIR) is a predominant diabetic microvascular complication that may cause vision loss. Retinal inflammation and angiogenesis contribute largely to the neuronal degeneration in DIR. The current study is aiming to test the effect of oral betanin doses in protection from DIR in rats along with a network pharmacology study to investigate an assumption that betanin may inhibit nuclear factor-\u03ba B (NF-\u03baB). Three rat groups were assigned as vehicle, DIR, and DIR\u00a0+\u00a0Betanin 100\u00a0mg/kg. Molecular docking indicated the possible binding between betanin and NF-\u03baB while the bioinformatic study highlighted a relation between this possible inhibition and suppression of NOD-like receptor pyrin domain-containing protein 3/vascular endothelial growth factor (NLRP3/VEGF) axis. The rat experimental study validated this assumption and indicated a protective effect for betanin on rat retinas as shown by routine hematoxylin and eosin staining (retinal thickness and ganglion cell count) and periodic acid-Schiff staining that was mediated through mitigating expression/protein level for of NF-\u03baB, NLRP3, TNF-\u03b1, IL-6 and VEGF proteins. Immunohistochemistry showed that betanin was able to suppress retinal content of the glial fibrillary acidic protein (GFAP). In conclusion, the current study indicated that betanin was a good candidate for DIR in rats through suppression of the inflammatory cascade and may be suggested for diabetic patients if appropriated clinical studies will be available.\n\nID: 41425077\nTitle: Neuritin: a multifaceted neuroprotective factor with emerging applications for neurodegeneration.\nAbstract: Neuritin is a conserved, activity-regulated gene encoding a glycosylphosphatidylinositol-anchored protein, crucial for neural development, synaptic plasticity, and neuroprotection. Identified via activity-dependent gene screening in the rat hippocampus, neuritin promotes neurite outgrowth, dendritic arborization, and synaptic maturation with neural activity. In this review, we summarize recent findings regarding neuritin's signaling pathways, neuroprotective, neuroregenerative, and neuromodulatory properties, with a focus on its therapeutic potential to counter neurodegeneration in various conditions such as glaucoma, Alzheimer's disease, stroke, diabetic neuropathy, and neuropsychiatric disorders. Additionally, recent studies reveal roles in immunoregulation, angiogenesis, and cancer biology, highlighting neuritin as a versatile signaling molecule with broad therapeutic implications.\n\nID: 41419594\nTitle: Longitudinal changes in each retinal layer thickness in diabetic retinopathy patients treated with pan-retinal photocoagulation.\nAbstract: To identify longitudinal changes in each retinal layer thickness in diabetic retinopathy (DR) patients who underwent pan-retinal photocoagulation (PRP). The subjects were divided into three groups: type 2 diabetes patients without DR (DM group), those with DR (DR group), and those who underwent PRP\u2009\u2265\u20096 months earlier (PRP group). Following the baseline visit, patients underwent three additional assessments at 1-year intervals. In total, 297 eyes were included: 87, 124, and 76 in the DM, DR, and PRP groups, respectively. The baseline ganglion cell complex (GCC) thickness was 110.4\u2009\u00b1\u200913.4, 112.5\u2009\u00b1\u200913.2, and 116.1\u2009\u00b1\u200917.6\u2009\u03bcm in the DM, DR, and PRP groups, respectively (P\u2009=\u20090.047). The baseline thickness of inner nuclear layer (P\u2009=\u20090.026) and outer plexiform layer (P\u2009=\u20090.002) differed significantly, which was significantly thicker in the PRP group. The photoreceptor layer and retinal pigment epithelium thicknesses differed significantly among the groups (both P\u2009<\u20090.001), and those in the PRP group were significantly thinner than in the other groups. In the PRP group, there were significant decreases in GCC and outer nuclear layer (ONL) thickness over time, while the other layers did not change significantly. The GCC (estimate\u2009=\u2009-0.15, P\u2009=\u20090.012) and ONL (estimate\u2009=\u2009-0.16, P\u2009=\u20090.019) thicknesses were significantly associated with changes in best-corrected visual acuity. The thickness of each retinal layer of patients who underwent PRP changed differently over time, and these changes were significantly associated with changes in visual acuity.\n\nID: 41411089\nTitle: Optic Atrophy Predominant WFS1 Disorder-A Case-Control Study.\nAbstract: Wolfram syndrome type 1 (WS1), or \"DIDMOAD\" (diabetes insipidus, diabetes mellitus, optic atrophy (OA), and deafness, OMIM #222300), is a rare neurodegenerative disorder resulting from homozygous, compound heterozygous autosomal recessive (AR), or rarely autosomal dominant mutations in the WFS1 gene. Isolated OA with adult-onset, milder phenotypes in WS1 is rare and typically associated with biallelic AR mutations. We describe 7 patients of pauci-syndromic WS1 presenting with adult-onset OA and compare parameters of visual function with other OA-predominant syndromes. A retrospective review was performed identifying records of patients seen at our institution from January 1, 2020, through December 31, 2024, who were found to have OA secondary to mutations in OPA1 (n = 9), WFS1 (n = 7), POLG (n = 3), mutations causing Leber hereditary optic neuropathy (LHON) (n = 17) or isolated OA from other genetic causes (n = 7). Patients were excluded who harbored confounding causes of vision loss and nongenetic causes of OA. Clinical data of visual function were recorded, including mean deviations and foveal sensitivities on automated visual fields (AVF), and ganglion cell complex (GCC) and peripapillary retinal nerve fiber layer (RNFL) thickness on optical coherence tomography (OCT). Visual acuities from initial neuro-ophthalmology consultation were recorded in logMAR format. Statistical analysis was performed on continuous variables. This study was granted exempt status by our institutional IRB. Compared with other OA syndromes, patients with LHON had the most severe average AVF and foveal sensitivity depressions and the lowest presenting logMAR acuity. Patients with WS1 in our cohort had significantly later onset of symptoms and delayed presentation compared with other OA syndromes. Patients with WS1 were significantly more likely to present with arcuate scotomas compared with other genetic OA syndromes, while patients with LHON and patients with OPA1 mutations (autosomal dominant optic atrophy [ADOA]) presented commonly with central scotomas and blind spot enlargement, respectively. WS1 diagnosis was not significantly associated with any specific pattern of thinning on OCT of the RNFL or GCC. ADOA diagnosis was associated with the most peripapillary RNFL thinning overall of all OA syndromes, most significantly in the superior and inferior quadrants. Our cohort of patients with WS1 showed uncharacteristically mild vision loss and minimal syndromic features, suggesting that a milder alternative phenotype with WFS1 mutations is possible in contrast to the traditional DIDMOAD syndrome. Compared with other OA syndromes, these patients with WS1 showed significant associations with arcuate visual field defects and trends toward superior/inferior peripapillary RNFL thinning. This suggests that relative preservation of papillomacular bundle fibers and thus milder central visual acuity loss may be a unifying feature in their phenotype. This series expands the clinical spectrum of WS1 and should encourage further work to study the pathogenic role of wolframin in vision loss. Clinicians should consider Wolfram syndrome in cases of adult-onset, symmetric, near-isolated OA, especially in cases with arcuate field defects, which are more commonly seen than in other genetic syndromes.\n\nID: 41409930\nTitle: Retinal Ganglion Cell Senescence Links Diabetes to Retinal Neurodegeneration.\nAbstract: Background Diabetic retinopathy (DR) is a leading cause of blindness worldwide and traditionally considered a microvascular complication. However, accumulating evidence indicates that retinal neurodegeneration is also crucial in DR pathogenesis. Retinal ganglion cells (RGCs), the output neurons of the retina, are particularly vulnerable to diabetic stress. Cellular senescence has been implicated in diabetes-related tissue damage, but its contribution to RGC degeneration remains unclear. We hypothesized that diabetes contributes to retinal neurodegeneration by inducing senescence in RGCs. Methods In streptozotocin (STZ)-induced diabetic mice, retinal function was assessed via full-field electroretinography (ERG), and molecular changes were evaluated in senescence markers. The expression of p16INK4a and monocyte chemotactic protein-1 (MCP-1) in retinal tissue was evaluated by enzyme-linked immunosorbent assay (ELISA) and quantitative real-time polymerase chain reaction (qRT-PCR), and the localization of p16INK4a was confirmed by immunostaining. To explore the direct effects of senescence, primary RGCs isolated from rat retina were exposed to oxidative stress or treated with the CDK4/6 inhibitor palbociclib. The isolated RGCs were analyzed via senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) staining and live-cell neurite imaging. Results The STZ-induced diabetic mice exhibited significant hyperglycemia without weight loss. ERG revealed markedly reduced amplitudes of the a-wave, b-wave, and oscillatory potentials, indicating impaired retinal neural function. Molecular analyses revealed significant upregulation of MCP-1 and p16INK4a at mRNA and protein levels. Immunostaining demonstrated p16INK4a co-expression in a subset of NeuN-positive cells within the ganglion cell layer, suggesting RGC senescence. Palbociclib-induced senescence (confirmed by SA-\u03b2-gal positivity) in vitroresulted in progressive neurite shortening in RGCs. Similarly, oxidative stress induced by antioxidant-free culture conditions caused neurite degeneration, highlighting the dual contributions of oxidative stress and senescence to RGC injury. Conclusions Cellular senescence was identified as a critical mechanism underlying RGC dysfunction in diabetes. Diabetes was found to induce retinal senescence and senescence-associated secretory phenotype activation, with RGCs exhibiting senescence-associated changes. Moreover, oxidative stress and pharmacologically induced senescence directly impaired RGC morphology and function in vitro. These results expanded our understanding of DR from a solely vascular disorder to a neurodegenerative disease, providing mechanistic insights into the role of senescence in retinal aging and neuronal susceptibility in diabetes.\n\nID: 41294828\nTitle: Autophagy Impairment in Retinal Ganglion Cells Following Hypoglycemia in Mice.\nAbstract: (1) Background: Diabetic retinopathy (DR), caused by hypo- and hyperglycaemia, is the leading cause of blindness. Hypoglycemia induces endoplasmic reticulum stress and retinal cell death in mice, and low-glucose conditions induce macroautophagy/autophagy defects in 661W photoreceptor cells and retinal explants. Very few studies have analyzed the effect of hypoglycemia on retinal autophagy, so we decided to fill this gap. (2) Methods: We use C57BL/6 and GFP-LC3 mice and isolated retinal ganglion cells (RGCs) from both mouse models to study the autophagy process. (3) Results: Intraocular injection of rapamycin and 5 h hypoglycemia showed an increase in autophagosomes formation, specifically in the RGCs. Isolated GFP-LC3 RGCs showed an increase in autophagosome formation under low-glucose conditions. In contrast, infection of isolated C57BL/6 RGCs with the RFP-GFP-LC3 lentivirus revealed a defect in autophagosome/lysosome fusion under these conditions. (4) Conclusions: This study showed that 5 h hypoglycemia induces autophagosomes formation in mouse RGCs; however, a defect in the fusion process inhibits the protective effect of autophagy. Therefore, modulating both autophagic and apoptotic pathways might be important to avoid complications associated with DR.\n\nID: 41266111\nTitle: M\u00fcller cell glutamine metabolism links photoreceptor and endothelial injury in diabetic retinopathy.\nAbstract: We characterized the timeline of molecular dysfunction in diabetic retinopathy (DR) and diabetic retinal disease (DRD) by studying the streptozotocin (STZ)-induced mouse retina over the course of 6 mo of diabetes. We performed bulk RNA-Seq on endothelial and retinal cells, separately, at 1, 3, and 6 mo of diabetes and single-cell RNA-Seq (scRNA-Seq) at 3 months. Transcriptomics changes were validated by in vitro and ex vivo assays and immunohistochemistry of mouse and human tissue. Bulk RNA-Seq revealed inflammation in endothelial cells at 1 mo. At 3 mo, scRNA-Seq identified glutamine-driven anaplerotic dysfunction in M\u00fcller cells, confirmed by retinal culture. We posited this glutamine deficiency would impact the photoreceptors and endothelial cells. We validated this hypothesis using endothelial cells in vitro, and immunohistochemistry of disrupted photoreceptor ribbon synapses in mouse and human diabetic retinas. In addition, glutamine deprivation increased the expression of apoptotic genes in endothelial cells. At 6 mo, we observed significant down-regulation of angiogenic pathways and elevated profibrotic markers. Our results suggest that dysfunction of the metabolic ecosystem linking the M\u00fcller-photoreceptor-endothelial cells is central to the early stages of DRD pathogenesis, impacting photoreceptor synapses and endothelial cells, before the appearance of the classic microvascular features of DR.\n\nID: 41237937\nTitle: Inhibition of serine racemase prevents retinopathy in diabetic mice.\nAbstract: A single-nucleotide polymorphism in the serine racemase (SRR)-encoding gene, Srr, is associated with an increased risk of type 2 diabetes. Studies, including our own, demonstrate that SRR is linked to a complication of diabetes, diabetic retinopathy (DR), and deletion of Srr protects diabetic animals from developing retinopathy. We investigate the feasibility and mechanisms of SRR inhibition as a strategy to prevent DR. SRR proteins in the retinas of db/db mice were approximately 50\u00a0% higher than C57BLKS/J wild-type (WT) mice, while D-serine levels in the aqueous humor were more than two-fold higher. Oral gavage of l-aspartic acid \u03b2-hydroxamate (L-ABH) improved b-wave amplitudes in electroretinogram recordings under both photopic and scotopic conditions. It also protected the inner retina in db/db mice by reducing the loss of retinal ganglion cells, endothelial cells, and pericytes, as well as decreasing the activation of M\u00fcller cells. In high glucose and hypoxia, interleukin-1 and interleukin-18 mRNA levels were lower in Srr-deleted M\u00fcller cell cultures than in WT cultures. Intravitreal injection of L-ABH mitigated glutamate-induced neurotoxicity in the retina. Systemically, L-ABH maintained euglycemia and improved glucose tolerance in db/db mice by inhibiting liver gluconeogenesis through restricting the expansion of pancreatic islet \u03b1-cells. Altogether, our results demonstrate that SRR inhibition prevents retinopathy in diabetic animals by blocking excitotoxicity and M\u00fcller cell-mediated inflammation in the retina, while also maintaining glucose homeostasis. This is the first demonstration that pharmacological blockade of SRR improves retinopathy and normalizes glucose levels in a type 2 diabetes model.\n\nID: 41192576\nTitle: Homocysteine and diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR), a leading cause of blindness in working-age adults, is a complex neurovascular complication of diabetes mellitus. Beyond chronic hyperglycemia, hyperhomocysteinemia (HHcy) has emerged as a significant modulator of DR progression. This review delineates the multifaceted role of HHcy in disrupting the retinal neurovascular unit, detailing its pathogenic impact on endothelial cells, neurons (particularly retinal ganglion cells), glial cells, and the retinal pigment epithelium. The molecular mechanisms involve a synergistic interplay of oxidative stress, inflammation, endoplasmic reticulum stress, mitochondrial dysfunction, and epigenetic dysregulation, culminating in blood-retinal barrier breakdown, neurodegeneration, and pathological angiogenesis. While preclinical evidence robustly demonstrates a direct and synergistic effect of homocysteine with hyperglycemia in driving retinal injury, clinical associations remain contentious due to heterogeneity in study populations, confounding factors like renal function, and methodological variations. We critically evaluate this translational evidence and explore the therapeutic potential of targeting homocysteine metabolism through B vitamins, betaine, and other strategies. Despite promising preliminary data, the field requires well-designed randomized controlled trials, informed by lessons from cardiovascular research, to definitively establish HHcy as a modifiable risk factor and to validate the efficacy of precise, personalized interventions for DR.\n\nID: 41137890\nTitle: Ginkgo Biloba extract attenuates diabetic retinopathy progression by modulating TP53 ubiquitination in a rat model.\nAbstract: Diabetic retinopathy (DR) is a microvascular complication of diabetes characterized by damage to the retina's neurons and blood vessels. Ginkgo biloba extract (GBE) has demonstrated neuroprotective properties, however, its specific mechanisms in DR remain incompletely understood. This research aims to elucidate the underlying mechanisms of GBE in DR. A diabetic rat model was induced with streptozotocin (STZ) and divided into control, diabetic, and GBE-treated groups. Retinal tissues of each group were analyzed using histology, TUNEL staining, and immunofluorescence. Bioinformatics identified potential GBE targets for DR, and protein-protein interaction network analysis prioritized core targets. Western blot and immunoprecipitation assays were used to detect protein expression and ubiquitination status. We successfully constructed the DR rat models and observed that GBE intervention effectively reverses diabetes-induced hyperglycemia and mitigates retinal ganglion cell (RGC) damage in the DR rat model. TUNEL staining indicates GBE's protective role against RGC apoptosis induced by DR. Bioinformatics identified 135 GBE targets in DR, with a focus on apoptosis pathways. Critically, we demonstrated an upregulation of TP53 expression in the retinal tissues of the DR rat model, an effect that was successfully reversed following GBE intervention. Notably, GEB increased TP53 ubiquitination, suggesting a potential modulation of TP53 stability and function. GBE attenuates DR progression by modulating TP53 ubiquitination in a rat model. The findings highlight the potential therapeutic benefits of GBE in DR and suggest further investigation into its mechanisms and broader bioactivity pathways.\n\nID: 41130930\nTitle: To ac tap or not to ac tap: Multi-centre outcomes of patients receiving anti-VEGF injections.\nAbstract: PurposeTo compare intraocular pressure (IOP) and retinal nerve fibre layer (RNFL) thickness in patients receiving intravitreal anti-vascular endothelial growth factor (VEGF) injections with and without anterior chamber paracentesis (ACP).MethodsThis multicentre retrospective cohort study included 269 injection-na\u00efve eyes from 210 patients with neovascular age-related macular degeneration (AMD) or diabetic macular oedema (DME). A matched subset of 140 eyes (70 with ACP, 70 without) was selected based on age, sex, diagnosis, laterality, and number of injections. RNFL thickness (overall and by quadrant) was measured at baseline and one-year follow-up. Additional outcomes included IOP, visual acuity (VA), and central retinal thickness (CRT).ResultsThe matched cohort had a mean age of 71.06\u202f\u00b1\u202f11.44 years, with 61.4% female participants. ACP eyes had worse baseline VA, higher IOP, and thicker CRT (p\u2009<\u20090.050, for all), but showed greater VA improvement (p\u2009=\u20090.023) and a trend towards greater CRT reduction (p\u2009=\u20090.061). RNFL thinning over one year did not differ between the groups (-3.24\u2009\u00b1\u200911.82\u2005\u00b5m vs -2.95\u2009\u00b1\u20097.81\u2005\u00b5m, p\u2009=\u20090.883). No major complications were observed.ConclusionACP did not significantly reduce RNFL thinning over one year but was well tolerated. It may be considered in patients at higher risk from transient IOP elevations. Future prospective studies are warranted to clarify its role in specific patient subgroups.\n\nID: 41101191\nTitle: Thickness profile of the ganglion cell complex and choroid in patients with persistent diabetic macular edema.\nAbstract: About 40\u00a0% of patients with diabetic macular edema (DME) do not respond optimally to first-line treatment with intravitreal injection of anti-vascular endothelial growth factor (AVEGF). Evidence suggests that additional vascular and neurodegenerative mechanisms may be involved. This study aimed to characterise the thickness of the Ganglion Cell Complex (GCC) and investigate the Choroidal Vascularity Index (CVI) in patients with different patterns of therapeutic response to AVEGF DME. This cross-sectional study included 27 diabetic patients into 3 different groups based on their response to AVEGF therapy: control group, responder DME group, and persistent DME group. The study's approach to vascular and neurodegenerative imaging biomarkers involved three steps: (1) Automatic quantification of GCC thickness, with manual correction when necessary; (2) Semi-automatic measurement of choroidal thickness; and (3) Analysis of choroidal area and choroidal luminal area using ImageJ software to calculate the CVI. In the overall characterization of the sample, a significant difference was observed only in the Best Corrected Visual Acuity (BCVA). There was a significant difference in Average Retinal Thickness (1\u00a0mm, 3\u00a0mm, and 6\u00a0mm) between the 3 groups and in GCC thickness at 1\u00a0mm. BCVA was negatively correlated with mean retinal thickness, while CVI showed a potential positive correlation with BCVA. While demographic and general clinical characteristics showed minimal differences across the groups, important differences in GCC and choroidal characteristics were observed. GCC (1\u00a0mm) may be interesting to explore in predicting visual outcomes after treatment, and CVI may impact visual gain.\n\nID: 41083790\nTitle: Retinal degeneration driven by brain-derived neurotrophic factor deficiency in microglia and T-lymphocytes.\nAbstract: Neurodegenerative diseases, such as glaucoma or multiple sclerosis, are characterized by progressive neuronal loss involving diverse pathogenic mechanisms. The brain-derived neurotrophic factor (BDNF) has been implicated in neuroprotection and neural plasticity, yet its regulation and involvement in retinal neurodegenerative diseases remain largely unclear. In this study, we investigated the impact of BDNF deficiency in immune cells on retinal integrity. Using mice with a conditional BDNF knockout in microglia/macrophages and T-cells or selectively in microglia/macrophages, we analyzed retinal changes at 3 and 7 months of age, with wildtype mice as controls. BDNF-deficient mice exhibited early and progressive degeneration of retinal ganglion cells and photoreceptors, accompanied by pronounced astrogliosis, which was exacerbated in aged animals. In 7-month-old mice, adaptive changes in synapses could be documented, evidenced through enhanced expression of the vesicular acetylcholine transporter. These findings demonstrate that BDNF from immune cells plays a crucial role in maintaining retinal homeostasis and that its loss promotes retinal neurodegeneration. Targeting immune cell-derived BDNF may offer novel therapeutic strategies for retinal involvement in neurodegenerative diseases with implications for treatment of glaucoma or multiple sclerosis.\n\nID: 41024545\nTitle: Role of Macular Ganglion Cell Complex Analysis for Diagnosis of Glaucoma Using Spectral Domain Optical Coherence Tomography.\nAbstract: Glaucoma is chronic progressive irreversible optic neuropathy characterized by significant visual field (VF) loss. So, early diagnosis and proper treatment can preserve the useful vision in lifetime. The objective of the study was to determine the importance of ganglion cell complex (GCC) analysis as a parameter for diagnosis of glaucoma. This case control study was conducted in the Department of Ophthalmology, Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) General Hospital, Bangladesh over a period of one year from July 2017 to June 2018. Twenty five (25) Type-2 Diabetes control subjects and 50 subjects with Type-2 diabetes were divided into two groups, 25 diabetic with pre perimetric and 25 diabetic with perimetric glaucoma. In this study, there was no significant difference in age (50.92\u00b15.53 years vs. 52.44\u00b14.75 years vs. 52.64\u00b17.80 years), gender. Regarding Optical coherence tomography (OCT) Retinal Nerve Fiber Layer (RNFL) of right eyes of the study subjects, superior and inferior RNFL were significantly thinner in both pre-perimetric right eye (109.18\u00b18.95 and 111.21\u00b110.53) and perimetric right eye (90.28\u00b18.94 and 91.51\u00b17.87) comparing normal eyes (129.12\u00b12.68 and 132.17\u00b13.22). Superior and inferior RNFL were significantly lower in both pre-perimetric (110.13\u00b111.53 and 113.75\u00b19.61) and perimetric (95.93\u00b115.08 and 93.29\u00b112.68) left eyes comparing normal left eyes (129.71\u00b15.50 and 132.57\u00b15.22). Regarding OCT GCC layer of right eyes of the study subjects, superior and inferior GCC layer were significantly lower in both pre-perimetric (87.66\u00b13.81 and 89.70\u00b14.98) and perimetric (77.48\u00b16.97 and 79.21\u00b16.06) right eyes comparing normal eyes (104.53\u00b12.73 and 106.88\u00b13.29). Regarding OCT GCC layer of left eyes of the study subjects, superior and inferior GCC layer were significantly lower in both pre-perimetric (84.88\u00b13.82 and 87.21\u00b13.77) and perimetric (81.08\u00b19.51 and 80.01\u00b110.02) left eyes comparing normal eyes (102.64\u00b12.29 and 105.20\u00b11.27). GCC parameter is useful tool for diagnosis of Glaucoma. It has same ability to discriminate eyes with glaucoma and non glaucomatous eyes compared to RNFL. In glaucoma, GCC layer is significantly thin which correlates strongly with glaucomatous damage. According to our result GCC layer analysis is important investigation to diagnosis of Glaucoma.\n\nID: 41002420\nTitle: The Form and Function of Retinal Ganglion Cells in Diabetes.\nAbstract: This review examines how diabetes affects the ganglion cells of the retina, including the axons that make up the optic nerve. Links between established changes in the morphology of retinal ganglion cells (RGCs) and vision loss, as well as other functions, such as the pupillary light reflex, are considered. RGC morphology and function are significantly altered in both animal models and humans with diabetes. Diabetes affects all parts of the RGC, including the dendrites, the cell body, the axons making up the nerve fiber layer, and the optic nerve. Subtypes of RGCs appear to be affected differently by diabetes, and the morphology and electrophysiological output are more significantly affected in ON-RGCs than in OFF cells, which may explain part of the mechanism underlying the widely documented diabetes-induced reduction in contrast sensitivity. Furthermore, the morphology of the specialized light-sensitive melanopsin-containing RGCs also appears to be affected by diabetes, which may explain deficits in circadian rhythm and the pupillary light reflex. Potential therapeutic approaches aimed at protecting RGCs in diabetes are also discussed. Overall, strong evidence supports the conclusion that diabetes impacts the form and function of RGCs and their axons within the optic nerve, resulting in deficient regulation of circadian rhythms and the pupillary light reflex, in addition to vision.\n\nID: 40976316\nTitle: Longitudinal Neural and Microvascular Changes in Type 2 Diabetic Patients Without Retinopathy: A 2-Year Prospective Cohort Study.\nAbstract: To compare the 2-year longitudinal changes in macular ganglion cell-inner plexiform layer thickness (GCIPLT) and superficial capillary plexus (SCP) vessel density between patients with type 2 diabetes mellitus (T2DM) without retinopathy (non-DR) and healthy controls. Prospective observational cohort study. T2DM patients without clinical retinopathy at baseline and after a 2-year follow-up, along with age- and sex-matched healthy controls, were recruited from the community in Guangzhou, China. Measurements of macular GCIPLT, retinal thickness (RT), and SCP vessel density were conducted at baseline and at the 2-year follow-up. Linear mixed-effects models were used to estimate absolute and relative rates of changes and to compare absolute rates between the 2 groups. A total of 282 eyes (141 in the control group and 141 in the non-DR group) were included in the analysis. Significant reductions in GCIPLT and GCIPLT/RT occurred only in the non-DR group, with GCIPLT decreasing by -0.229 \u00b5m/y (95% CI = -0.313 to -0.144; P < .001) and 0.324 % (95% CI = 0.444 to 0.204; P < .001), approximately 5-fold faster than in the control group. After adjusting for confounding factors, the longitudinal rates of RT, GCIPLT, and GCIPLT/RT were significantly accelerated in the non-DR group compared to the control group by -0.603 \u00b5m/y (95% CI = -0.939 to -0.268; P < .001), -0.189 \u00b5m/y (95% CI = -0.306 to -0.073; P = .001), and -0.073 % (95% CI = -0.118 to -0.028; P = .001), respectively. Although longitudinal changes in SCP vessel density did not show significant differences between the 2 groups (P = .861). Our findings suggest that neurodegenerative changes may precede microvascular alterations in non-DR patients, indicating that monitoring of GCIPLT is crucial for patients with long-standing diabetes, even in the absence of retinopathy.\n\nID: 40971499\nTitle: Comparative analysis of retinal thickness between type 1 and type 2 diabetes mellitus patients with similar disease duration: A cross-sectional study.\nAbstract: To assess the retinal thickness in patients with type 1 diabetes mellitus (T1DM) and type 2 DM (T2DM) of equal disease duration, comparing them with age- and sex-matched healthy controls. This cross-sectional, comparative, and observational study included 96 participants, categorized into four groups: A1 (patients with T1DM, n = 24), A2 (age- and sex-matched nondiabetic controls for A1, n = 24), B1 (patients with T2DM, n = 24), and B2 (age- and sex-matched nondiabetic controls for B1, n = 24). Evaluations included retinal nerve fiber layer (RNFL) thickness, ganglion cell complex (GCC) thickness, central macular thickness (CMT), visual acuity, color vision, and contrast sensitivity. The primary objective was to compare RNFL, GCC, and CMT between T1DM and T2DM patients with equivalent disease duration and their respective controls. Secondary analyses assessed differences in visual acuity, color vision, and contrast sensitivity between T1DM and T2DM patients. The mean age of T2DM patients was 50.96 years, and for T1DM patients it was 28.96 years. T2DM patients exhibited significant GCC reduction in the superonasal ( P = 0.046) and inferonasal quadrants ( P = 0.048) compared to T1DM. T2DM also showed significant RNFL thinning in the superior ( P = 0.037), inferior ( P = 0.012), and temporal quadrants ( P = 0.025) compared to T1DM after adjustment for age and DM duration. No significant difference in CMT was observed between T1DM and T2DM. In T1DM patients, mean best-corrected visual acuity was significantly worse than that of controls ( P = 0.019). Contrast sensitivity and color vision did not differ significantly between T1DM and T2DM. This study reveals earlier RNFL and GCC thinning in T2DM compared to T1DM.\n\nID: 40967391\nTitle: SPG302 protects retinal ganglion cells and preserves visual function by preserving synaptic activity in a mouse model of glaucoma.\nAbstract: Glaucoma, a leading cause of irreversible vision loss worldwide, is an optic neuropathy characterized by optic nerve degeneration and retinal ganglion cell (RGC) death. Early glaucomatous damage is often associated with dendritic and synaptic abnormalities in RGCs, yet the mechanisms linking these synaptic alterations to RGC death remain unclear. In a mouse model of glaucoma, treatment with the clinical-stage, synaptogenic small molecule SPG302, a pegylated benzothiazole derivative, demonstrated neuroprotective effects, protecting RGCs and their axons in the glaucomatous retina and also improving retinal function as assessed by pattern electroretinogram testing. Elevated intraocular pressure disrupted synapses, as evidenced by reduced synaptophysin expression and homeostatic increases in Bassoon and PSD95 levels in the inner plexiform layer. SPG302 treatment effectively preserved synaptic integrity by reversing these changes. These findings highlight the therapeutic potential of SPG302 for protecting RGCs and preserving vision by modulating synaptic activity in glaucomatous neurodegeneration.\n\nID: 40939765\nTitle: Retinal neurodegeneration and choroidal changes of early diabetes in peripapillary region detected by swept-source optical coherence tomography angiography.\nAbstract: This study was designed to evaluate peripapillary retinal nerve fiber layer (pRNFL) and choroidal alterations in diabetic patients without diabetic retinopathy (NDR), and further explore their association utilizing ultrawide-field swept-source optical coherence tomography angiography (UWF-SS-OCTA). This cross-sectional study included 169 eyes of 169 NDR subjects and 54 eyes of 54 healthy controls. pRNFL, choroidal thickness and volume were compared and measured with UWF-SS-OCTA. The association between pRNFL and choroidal parameters was assessed with Spearman correlation analysis. Further multivariate linear regression analysis was performed to evaluate their relationship after adjusting for confounding factors. Compared with healthy controls, NDR patients showed reduced choroidal thickness and volume in the full range and several peripapillary subfields, while a statistical decrease of pRNFL was only detected in the inferior quadrant (P\u00a0=\u00a00.04). Regarding the distribution profiles in the peripapillary region, the choroid was thickest in the temporal region and thinnest in the inferior region, and a more prominent decrease compared with controls was found in the inferior region. Average pRNFL thickness was independently associated with full-range mean choroidal volume in multiple regression analysis (\u03b2\u00a0=\u00a00.16, P\u00a0=\u00a00.04). As two early signs of DR, choroidal thinning could precede retinal neurodegeneration. Decreased choroidal thickness may account for the susceptibility of RNFL thinning.\n\nID: 40833325\nTitle: Differential Expression of the Synapse Regulatory Proteins Neurexins in Early Diabetic Retinal Disease.\nAbstract: Neurexins (NRXNs), a complex family of synapse regulatory proteins, represent attractive candidate molecular mediators of retinal neuronal dysfunction in early diabetic retinal disease (DRD) given their roles in the central nervous system and recent work suggesting a potential link with diabetes mellitus (DM). As antibodies are unable to distinguish NRXN family members and isoforms, the purpose of this study was to investigate differential expression of individual NRXN transcripts in relevant retinal cell types in early DRD. RNAscope multiplexed fluorescent in situ hybridization was used to quantify transcripts of NRXNs in mouse and human retina. DM was induced in C57BL/6J mice using streptozotocin (STZ) and the retinal phenotype characterized by electroretinogram (ERG), optical coherence tomography (OCT), and optokinetic tracking (OKT) after 6 weeks. Retinal ganglion cells (RGCs) were generated in vitro by directed differentiation from human embryonic stem cells (hESCs), cultured in normal or high glucose, and NRXN expression assessed by qPCR and Western blot. All NRXN family members (NRXN1, NRXN2, and NRXN3) were enriched in inner retinal neurons in both human and mouse tissue. We identified decreased Nrxn3 transcripts, specifically the Nrxn3\u03b2 isoform, in RGCs of diabetic mice at 6 weeks after STZ treatment. Interestingly, Nrxn3\u03b1 and Nrxn3\u03b2 were differentially expressed in inner retinal layers. Finally, we confirmed decreased Nrxn3\u03b2 expression in hESC-RGCs cultured in high glucose in vitro. Our findings suggest that NRXNs may play cell-type-specific roles in the inner retina and associate decreased Nrxn3\u03b2 expression in RGCs with inner retinal dysfunction in early DRD.\n\nID: 40794319\nTitle: HuD and alpha-crystallin A axis protects neuro-retinal cells in early diabetes.\nAbstract: Diabetic retinopathy (DR) is a prevalent microvascular complication of diabetes; however, neuro-retinal degeneration is also observed in patients with diabetes without signs of DR. The mechanisms leading to neuro-retinal cell loss before vascular complications manifest in diabetes remain poorly understood. In this study, we investigated the neuronal RNA-binding protein HuD as a novel regulator of neuro-retinal degeneration in the early stage of diabetes. We determined the expression of HuD and alpha-crystallin A (CRYAA) in the retinal ganglion cell layer. HuD and CRYAA were down-regulated in the retinas of streptozotocin-induced diabetic rats and in neuro-retinal cells (R-28) treated with high glucose. Cryaa mRNA was identified as a novel target transcript of HuD, and we demonstrated that HuD post-transcriptionally regulates the expression of Cryaa mRNA by binding to its 3'-untranslated region. Silencing and overexpression of HuD positively regulated the expressions of Cryaa mRNA and protein. We demonstrated that the increase in inflammatory cytokines such as TNF\u03b1, IL-1\u03b2, and IL-6 in R-28 cells under hyperglycemic conditions was a result of both CRYAA and HuD levels. Silencing HuD and CRYAA enhanced high glucose-induced R-28 cell death, whereas their overexpression alleviated this effect. HuD post-transcriptionally regulates CRYAA expression, influencing the function and viability of neuro-retinal cells under diabetic conditions. Our results suggest that the HuD/CRYAA axis plays a crucial role in neuro-retinal cells and has the potential to serve as a prognostic factor and therapeutic target for diabetic neuro-retinal degeneration.\n\nID: 40779495\nTitle: In Silico identification and modelling of FDA-approved drugs targeting T-type calcium channels.\nAbstract: Studies have shown that inhibition of the Cav3.1 T-type calcium channel can prevent or suppress neurological diseases, such as epileptic seizures and diabetic neuropathy. In this study, we aimed to use in silico simulations to identify a U.S. Food and Drug Administration (FDA)-approved drug that can bind to the Cav3.1 T-type calcium channel. We used the automated docking suite GOLD v5.5 with the genetic algorithm to simulate molecular docking and predict the protein-ligand binding modes, and the ChemPLP empirical scoring function to estimate the binding affinities of 2,115 FDA-approved drugs to the human Cav3.1 channel. Drugs with high binding affinity and appropriate pharmacodynamic and pharmacokinetic properties were selected for molecular mechanics Poisson-Boltzmann surface area (MMPBSA) and molecular mechanics generalised Born surface area (MMGBSA) binding free energy calculations, GROMACS molecular dynamics (MD) simulations and Monte Carlo Cell (MCell) simulations. The docking results indicated that the FDA-approved drug montelukast has a high binding affinity to Cav3.1, and data from the literature suggested that montelukast has the appropriate drug-like properties to cross the human blood-brain barrier and reach synapses in the central nervous system. MMPBSA, MMGBSA, and MD simulations showed the high stability of the montelukast-Cav3.1 complex. MCell simulations indicated that the blockage of Cav3.1 by montelukast reduced the number of synaptic vesicles being released from the pre-synaptic region to the synaptic cleft, which may reduce the probability and amplitude of postsynaptic potentials.\n\nID: 40763825\nTitle: Hyaluronic acid methacryloyl-based co-delivery system for aflibercept and miR-21-3p antagomir: a dual-therapeutic approach for diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss characterized by concurrent retinal vascular dysfunction and neurodegeneration. While current therapies primarily target vascular dysfunction, they offer limited neuroprotective benefits. In this study, we developed a novel light-responsive hydrogel composed of hyaluronic acid methacryloyl (HAMA) for the co-delivery of aflibercept and miR-21-3p antagomir (HAMA@(Ab+M21A)). This dual-therapeutic strategy was designed to concurrently target retinal vascular dysfunction and neurodegeneration. Upon light exposure, HAMA hydrogel undergoes rapid in situ crosslinking, exhibiting excellent ocular biocompatibility and sustained drug release over 45\u00a0days, in parallel with controlled biodegradation. HAMA@(Ab+M21A) effectively inhibits VEGF-induced vascular dysfunction, suppresses reactive gliosis, and promotes retinal ganglion cell survival in vitro and in vivo. Collectively, this study demonstrates the therapeutic potential of HAMA@(Ab+M21A) as a dual-function strategy for DR, providing both anti-angiogenic and neuroprotective effects to impede disease progression.\n\nID: 40759398\nTitle: MiRNA-122-5p promotes retinal ganglion cell oxidative damage by targeting DJ-1 in hyperglycemic retina.\nAbstract: Mitochondrial dysfunction, induced by prolonged hyperglycemia, is widely regarded as a central factor in oxidative stress and retinal ganglion cell (RGC) degeneration in diabetic retinopathy (DR). DJ-1 (PARK7) acts as a crucial antioxidant defense mechanism, stabilizing mitochondrial structure and redox balance. However, its expression is dramatically suppressed under diabetic conditions, and the upstream regulatory mechanisms remain incompletely characterized. Growing evidence from epigenetic research implicates microRNAs (miRNAs) as important players in the molecular pathways underlying DR progression. Among these, miRNA-122-5p has drawn increasing attention due to its aberrant activity under diabetic stress and its putative interaction with PARK7. In this study, we employed a streptozotocin-induced type 1 diabetes mouse model and glucose-stimulated R28\u00a0cells to explore the contribution of miRNA-122-5p to mitochondrial damage, oxidative stress, and RGC injury. In diabetic mice, we observed significant oxidative imbalance, increased apoptotic activity, RGC loss, and diminished retinal function. MiRNA profiling identified miRNA-122-5p as the most upregulated among candidate miRNAs. Inhibition of miRNA-122-5p attenuated these pathological changes and preserved both cellular integrity and visual function. In vitro, high glucose triggered mitochondrial fragmentation, membrane potential collapse, and excessive reactive oxygen species generation in R28\u00a0cells. Suppressing miRNA-122-5p alleviated these injuries. Dual-luciferase assays confirmed that miRNA-122-5p directly targets PARK7, thereby post-transcriptionally repressing DJ-1 expression and compromising mitochondrial resilience. These findings establish miRNA-122-5p as a critical upstream regulator of DJ-1-mediated antioxidant defense. By aggravating mitochondrial oxidative stress, it contributes to RGC vulnerability in DR. Targeted modulation of miRNA-122-5p may offer a novel therapeutic approach to preserve retinal neurons and counteract neurodegeneration in DR.\n\nID: 40639562\nTitle: Protective effects of empagliflozin against NMDA-induced excitotoxicity in the rat retina.\nAbstract: Empagliflozin (EMPA), a sodium-glucose cotransporter 2 inhibitor used in patients with type 2 diabetes, exerts various beneficial effects, including anti-inflammatory and antioxidant properties, in addition to its glucose-lowering effect. In this study, we examined whether EMPA protects against N-methyl-d-aspartic acid (NMDA)-induced retinal excitotoxicity and the mechanisms underlying its protective effects. Male Sprague-Dawley rats (7-8\u00a0weeks old) were used in this study. The number of cells in the ganglion cell layer (GCL) decreased 7\u00a0days after intravitreal injection of NMDA (50\u00a0nmol). Simultaneous intravitreal injection of EMPA (50 and 100\u00a0nmol) and NMDA reduced NMDA-induced cell loss in a dose-dependent manner. The protective effect of EMPA was significantly attenuated by the AMP-activated protein kinase (AMPK) inhibitor, compound C (10\u00a0nmol). NMDA increased the number of terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive cells in the GCL 6\u00a0h after injection, and the response was significantly, but not completely, attenuated by EMPA. These results suggest that EMPA protects against NMDA-induced retinal excitotoxicity in rats. The protective effect of EMPA may be partly attributed to the activation of the AMPK pathway and inhibition of neuronal cell apoptosis.\n\nID: 40607869\nTitle: Diabetes-Induced Dysregulation of Peripapillary and Macular Neurovascular Units.\nAbstract: The aim of this study was to investigate the impact of diabetic retinopathy (DR) on macular and peripapillary neurovascular units (NVUs) by assessing optical coherence tomography (OCT)/OCT angiography-based macular and peripapillary NVU parameters. This study enrolled 182 eyes with type 2 diabetes mellitus (DM) eyes and 202 healthy control eyes. The eyes of DM patients were divided into DM without DR (DM/noDR; n = 136) and DR stage groups (n = 46). Macular NVU parameters consisted of ganglion cell-inner plexiform layer (GCIPL) thickness and macular perfusion density (PD). As for peripapillary NVU parameters, peripapillary retinal nerve fiber layer (RNFL) thickness, together with radial peripapillary capillary perfusion density (RPC-PD) and RPC flux index (RPC-FI), represented by peripapillary structural and functional vascular parameters, were also examined. Macular and peripapillary parameters were compared among three stages, and correlations between macular and peripapillary parameters were examined for each stage. Macular GCIPL thickness and macular PD decreased with stage progression, preserving positive correlations (i.e., preserving macular NVU) with each other in all eyes, but correlation coefficients were the lowest in DM/noDR eyes. Macular GCIPL thickness, as well as macular PD, positively correlated with peripapillary NVU parameters over the entire stages except macular PD and RNFL thickness in DR eyes (i.e., preserving macular and peripapillary NVU), but correlation coefficients were the lowest in DM/noDR eyes. Macular and peripapillary NVU were preserved throughout the stages: control, DM/noDR, and DR groups, but the linkage weakened at the onset of DM, suggesting diabetes-induced dysregulation of macular and peripapillary NVUs in subclinical DR.\n\nID: 40535992\nTitle: Longitudinal Association of Decreased Serum Uric Acid Level with the Thinning of Ganglion Cell Inner Plexiform Layer Thickness in Chinese Adults with Type 2 Diabetes Mellitus without Retinopathy.\nAbstract: To explore the associations between serum uric acid (SUA) level change and changes in the retinal neurodegenerative biomarkers in type 2 diabetes mellitus patients without retinopathy. This is a prospective observational cohort study based on the baseline and 1-year follow-up data of the Guangzhou Diabetic Eye Study. Type 2 diabetes mellitus patients without retinopathy were recruited. Thicknesses of ganglion cell inner plexiform layer (GC-IPL) and peripapillary retinal nerve fiber layer (pRNFL) were measured via swept-source optical coherence tomography. The associations between SUA level change and the thinning rates of GC-IPL and pRNFL were analyzed using multivariate linear regression analysis. Sub-group analysis based on sex was constructed. A total of 1084 participants were enrolled in our study. After adjustment, both male and female patients with decreased SUA levels in higher baseline SUA level group had a significantly slower thinning rate of GC-IPL than those with non-decreased SUA levels. In higher baseline SUA level with decreased SUA level group, male patients exhibited significantly slower thinning rate of inferior GC-IPL, while female patients exhibited significantly slower thinning rate of inferior and nasal GC-IPL and inferior pRNFL, when compared to those with non-decreased SUA levels. Our findings prove that decreased SUA level is associated with a slower GC-IPL thinning rate in higher baseline SUA level group, suggesting that decreased SUA level could be constituted as a potential future control target to delay the neurodegeneration in type 2 diabetes mellitus patients.\n\nID: 40464812\nTitle: RBM15 promotes m6A methylation and stability of KLF6 mRNA to accelerate pyroptosis of retinal ganglion cells in early-stage diabetic retinopathy.\nAbstract: Neurodegeneration in early-stage diabetes retinopathy (DR) is mainly caused by the loss of retinal ganglion cells (RGCs), and high glucose-treated cell pyroptosis contributes to an important cause. However, the detailed molecular regulatory mechanism has not yet been thoroughly examined. In this study, primary mouse RGCs were stimulated with different concentrations of glucose, and mouse was intraperitoneally injected with streptozotocin (STZ) to construct DR model in vitro and in vivo. We found that compared to normal controls, RNA binding motif protein 15 (RBM15) was significantly upregulated in high glucose-treated RGCs and STZ-induced mice. RBM15 silence restored cell viability and inhibited cell apoptosis and cell death in high glucose-triggered RGCs. In parallel, RBM15 knockdown distinctly improved pathological damage such as thinning of retinal tissue thickness and loss of RGCs in STZ-modeling mice. Interestingly, the production of inflammatory cytokines and the expression of Cleaved caspase-1, NLRP3 and GSDMD-N were significantly reduced by RBM15 silence in vivo and in vitro. Mechanistically, RBM15 bound to kruppel like factor 6 (KLF6) mRNA to promote m6A modification and stabilize KLF6 mRNA, upregulating KLF6 expression in model cells and model mice retinal tissues. KLF6 overexpression increased the production of inflammatory cytokines and the expression of proteins related to pyroptosis, reversing the protective effects of RBM15 silence in high glucose-treated RGCs and diabetic retina. In conclusion, RBM15 is upregulated by high glucose, and stabilizes KLF6 mRNA to activate NLRP3-mediated pyroptosis pathway, exacerbating inflammation and apoptosis of RGCs and accelerating the progression of DR.\n\nID: 40451313\nTitle: MiR-29a-5p engages in the mechanism of diabetic retinopathy by specifically targeting SIRT3.\nAbstract: Whether miR-29a-5p is associated with Diabetic Retinopathy (DR) is still a subject of ongoing discussion. The current research examines the involvement of miR-29a-5p in regulating apoptosis, oxidative stress, and inflammation of retinal ganglion cells (RGCs) generated by High Glucose (HG). Additionally, we are interested in analyzing the contribution of miR-29a-5p in DRdeveloping. We obtained peripheral blood samples from 7 people with DR and 14 individuals without DR. Subsequently, we conducted biochemical indices analyses and qRT-PCR.We randomly divided RGCs into low glucose groups, HG groups, HG + inhibitor negative control groups, and HG\u00a0+\u00a0miR-29a-5p inhibitor groups. SIRT3 siRNA was transfected into RGCs through lipofectamine 3000 reagent.Cell vitality was detected by MTT; qRT-PCR was applied to identify miR-29a-5p expression; Detectionof ROS, SOD, and MDAlevels was quantified using the DCFH-DA, WST-1, and colorimetric methods, respectively; IL-6 and TNF-\u03b1contents were analyzed utilizing ELISA; Dual-luciferase gene reporter experiment was used to examine if SIRT3 is the specific target gene of miR-29a-5p; Flow cytometryevaluatedapoptosisin RGCs; The technique of Western blotting identified the presence of caspase-3 proteins. The expression of miR-29a-5p was markedly elevated in individuals with DR, and it had positive correlations with levels of Total Cholesterol (TC) and Fasting Blood Glucose (FBG).High glucose significantly induced RGC apoptosis and upregulated the miR-29a-5p gene. Transfection of miR-29a-5p inhibitor protected RGCs against HG-induced oxidative injury, inflammation, and apoptosis. Furthermore, the dual-luciferase reporter experiment provided confirmation that SIRT3 was a target gene of miR-29a-5p, as it negatively regulated SIRT3 expression. Notably, SIRT3 knockdown abolished the protection of miR-29a-5p inhibition on RGCs. Suppression of the miR-29a-5p gene safeguards RGCs against harm caused by HG via boosting SIRT3 signaling, which might provide a new prevention and treatment strategy for DR.\n\nID: 40414590\nTitle: Macular Microvasculature Asymmetry Analysis for Evaluating Open-Angle Glaucoma in Diabetic Retinopathy Patients Treated With Pan-Retinal Photocoagulation.\nAbstract: To evaluate the usefulness of vertical asymmetry analysis of macular microvasculature for diagnosis of open-angle glaucoma (OAG) in diabetic retinopathy (DR) patients who have undergone pan-retinal photocoagulation (PRP). Retrospective, cross-sectional diagnostic evaluation. DR patients with PRP were categorized into those without OAG (Group 1) and those with OAG (Group 2). Peripapillary retinal nerve fiber layer (pRNFL) thickness and macular vessel density (VD) were measured, and the vertical difference in pRNFL (vdRNFL) and VD (vdVD) was determined as the absolute difference between the superior and inferior sectors. Diagnostic performance was analyzed by calculating the area under the curve (AUC). Analyses included 128 eyes (Group 1: 68 and Group 2: 60). The mean pRNFL thickness was 93.9 \u00b1 14.8 \u00b5m in Group 1 and 85.5 \u00b1 14.4 \u00b5m in Group 2 (P = .009). The mean vdRNFL was 13.1 \u00b1 10.9 \u00b5m in Group 1 and 14.4 \u00b1 12.6 \u00b5m in Group 2 (P = .607). The mean VD was 15.9 \u00b1 3.3 mm-1 in Group 1 and 15.3 \u00b1 2.6 mm-1 in Group 2 (P = .380), whereas the vdVD was 0.6 \u00b1 0.6 mm-1 in Group 1 and 1.6 \u00b1 1.4 mm-1 in Group 2 (P < .001). The AUC for diagnostic accuracy was 0.812 for vdVD, significantly higher than that for other factors (all P < .001). Relying on pRNFL thickness for OAG evaluation in PRP-treated patients is not recommended. Analysis of vertical microvasculature asymmetry can serve as a useful factor for diagnosing OAG.\n\nID: 40384765\nTitle: Serum pro-brain natriuretic peptide correlates with optical coherence tomography indices in diabetic retinopathy.\nAbstract: Serum pro-brain natriuretic peptide (BNP) is a 108-amino-acid prohormone that inhibits vascular endothelial growth factor (VEGF) secretion, protecting pericytes from cell death and decreasing retinal vascularization. The purpose of this study was to investigate the correlation of serum pro-BNP with optical coherence tomography (OCT) indices in diabetic retinopathy. This cross-sectional study investigated 96 consecutive subjects aged between 40 and 65 years: controls n = 24, no diabetic retinopathy (NoDR) n = 24, non-proliferative diabetic retinopathy (NPDR) n = 24, and proliferative diabetic retinopathy (PDR) n = 24. Same-day analysis of blood samples for serum pro-BNP levels was performed and spectral-domain OCT (SD-OCT) was used to measure the following OCT indices: OCT angiography (OCTA) superficial vessel density (SVD), deep vessel density (DVD), and foveal avascular zone (FAZ); OCT retinal nerve fiber layer (RNFL); and OCT ganglion cell analysis (GCA). The mean serum pro-BNP levels for the control, NoDR, NPDR, and PDR groups were 14.07 \u00b1 11.51, 27.35 \u00b1 11.81, 280.44 \u00b1 106.13, and 122.33 \u00b1 43.66 pg/ml, respectively. The mean values of the various OCT parameters correlated with serum pro-BNP were OCTA SVD (r = - 0.360), OCTA DVD (r = 0.408), OCTA FAZ (r = 0.475), OCT RNFL (r = - 0.215) and OCT GCA (r = - 0.285; p<0.001). The serum pro-BNP levels were higher in the NPDR group than in the NoDR group and much lower in the PDR group than in the NPDR group, reflecting a lowering of the protective barrier. These results correlated with the changes in various OCT indices.\n\nID: 42461932\nTitle: Structure function relationships differ between optic neuritis and glaucoma with comparable optical coherence tomography findings.\nAbstract: This retrospective study compared structure-function relationships between patients with optic neuritis (ON) and primary open-angle glaucoma (POAG), focusing on the extent of retinal nerve fiber layer (RNFL) and ganglion cell-inner plexiform layer (GCIPL) damage and its correlation with visual field (VF) defects. We included 194 patients (ON: 47; POAG: 147) referred to Yonsei University Severance Eye Hospital between 2017 and 2023. RNFL and GCIPL thickness, VF indices, and the relationship between structural and functional measures were assessed. Despite comparable RNFL and GCIPL thinning, ON demonstrated significantly better VF performance than POAG (mean deviation: -2.26 dB vs. -7.32 dB; VF index: 95.48% vs. 80.43%; both p\u2009<\u20090.001). In POAG, VF loss was strongly correlated with structural parameters, whereas in ON, VF remained preserved even at low RNFL and GCIPL values. Linear regression with robust error estimation confirmed significant interaction between disease type and structure-function slopes (p\u2009<\u20090.01). These findings persisted after 1:2 propensity score matching for age and comorbidities (ON: n\u2009=\u200929; POAG: n\u2009=\u200958; all interaction p\u2009<\u20090.05), age-adjusted multivariable regression, and a sensitivity analysis restricted to non-diabetic participants (ON: n\u2009=\u200945; POAG: n\u2009=\u2009124; all interaction p\u2009<\u20090.001). This dissociation was evident at RNFL <90 \u00b5m and GCIPL <80 \u00b5m, where ON showed better VF indices than POAG with similar structural loss. The differences in structure-function relationships underscore the importance of disease-specific diagnostic approaches and unraveling the distinct mechanisms underlying ON and POAG to improve the management of visual impairments.\n\nID: 42461878\nTitle: Ocular Involvement in Childhood-Onset Sarcoidosis: A Case Series.\nAbstract: Childhood-onset sarcoidosis (COS) is a rare granulomatous autoinflammatory condition characterised by arthritis, dermatitis, and uveitis which includes early-onset forms (sporadic or Blau syndrome) and a later-onset form resembling adult sarcoidosis. Ocular involvement often occurs early and may be a prominent, sight-threatening feature. Despite this, COS is sparsely described in the literature. This case series aims to characterise the ocular manifestations, complications, and outcomes in COS. A review of patients diagnosed with COS under a tertiary paediatric uveitis service. Data collected included age at onset, clinical findings, diagnostic methods, treatments, ocular complications, and visual acuity (VA) at presentation and last follow-up. Six patients were identified, all of whom presented with granulomatous uveitis. Four had posterior segment involvement including choroiditis and optic disc swelling. The mean age of ocular disease onset was 7\u2009years. Diagnosis was supported by elevated serum angiotensin converting enzyme (ACE) followed by lymph node biopsy (n\u2009=\u20093), skin biopsy (n\u2009=\u20092), and/or NOD2 mutation (n\u2009=\u20093). All received systemic immunosuppression: methotrexate (n\u2009=\u20096), adalimumab (n\u2009=\u20095), mycophenolate (n\u2009=\u20092), oral corticosteroids (n\u2009=\u20093), and infliximab (n\u2009=\u20091). Complications included uveitic glaucoma (n\u2009=\u20092), cataract (n\u2009=\u20093), and chorioretinal scarring (n\u2009=\u20091). VA improved or remained stable in most, with one case of persistent visual impairment. COS-related uveitis demonstrates an aggressive, chronic course with early onset, bilateral involvement, and frequent complications with potential to cause visual loss. Careful ophthalmic screening in children with known or suspected sarcoidosis is critical.\n\nID: 42461625\nTitle: Factors Associated With Progression to Primary Angle Closure: A Post Hoc Analysis of the ANA-LIS Trial.\nAbstract: Identifying primary angle closure suspect (PACS) eyes at higher risk of progressing to primary angle closure (PAC) is clinically important. To evaluate baseline anterior segment risk factors associated with progression from PACS to PAC over 5 years. This post hoc analysis involves data from a randomized clinical trial (Singapore Asymptomatic Narrow Angles-Laser Iridotomy Study) conducted at 5 tertiary eye hospitals from November 1, 2004, to October 31, 2018. The original enrollment included 480 participants. Data analysis for this report was conducted from May to July 2025. All participants underwent comprehensive ocular examinations, including anterior segment optical coherence tomography (AS-OCT) and ultrasound biomicroscopy (UBM) at baseline, before laser peripheral iridotomy (LPI), and LPI in 1 randomly selected eye. PACS was diagnosed if the pigmented trabecular meshwork was not visualized for 2 or more quadrants on nonindentation gonioscopy. Progression was defined as development of PAC (intraocular pressure [IOP] >24 mm Hg and/or \u22651 clock hour of peripheral anterior synechiae, or an episode of acute angle closure). Risk factors for progression were assessed using univariable and multivariable generalized linear models (GLMs) with generalized estimating equations and Cox regression models clustered by participant. We estimated odds ratios (ORs) with 95% CI using GLM and hazard ratios (HRs) with 95% CI using Cox regression. Of the 480 participants originally enrolled, 161 (33.5%) underwent baseline AS-OCT and UBM. Among these participants, 123 (76.4%) were female and 38 (23.6%) male; the mean (SD) age was 62.9 (7.2) years. Overall, 16 of 322 eyes (5.0%, 7 with LPI and 9 without LPI) progressed. In the multivariable GLM model (area under the receiver operating characteristic curve\u2009=\u20090.83), higher baseline IOP (OR, 1.6 per 1 mm Hg; 95% CI, 1.2-2.1; P\u2009=\u2009.003) or a higher number of plateau iris quadrants on UBM (OR, 4.5 per quadrant; 95% CI, 1.6-13.0; P\u2009=\u2009.005) were associated with progression. In the multivariable Cox model adjusted for baseline IOP, trabecular-iris space area (TISA750; HR, 3.1 per -0.1 mm2; 95% CI, 1.3-7.5; P\u2009=\u2009.02) or the presence of plateau iris in \u22651 quadrant (HR, 11.1; 95% CI, 3.3-37.7; P\u2009=\u2009.001) were independently associated with greater risk of progression. An additional Cox model adjusting for iris curvature confirmed the associations of TISA750 (HR, 3.3; 95% CI, 1.3-8.6; P\u2009=\u2009.02) or plateau iris (HR, 12.5; 95% CI, 3.8-40.4; P\u2009<\u2009.001) with progression. Narrower anterior chamber angles, plateau iris configuration in more than 1 quadrant, or higher baseline IOP were associated with greater risk of progression.

For\u00a0patients with\u00a0chronic conditions requiring lifelong therapy, such as glaucoma, this disruption threatened continuity of care. We aimed to quantify the pandemic's impact on medication adherence and persistence using a large Italian administrative database. We conducted a retrospective cohort study using healthcare databases from Lombardy, Italy.\u00a0Established patients with glaucoma\u00a0(defined as\u2009\u2265\u20096 dispensations of ATC S01E medications with a glaucoma diagnosis) were identified in two time periods:\u00a02017 (2018 Cohort, followed from March 2018\u00a0before the pandemic) and\u00a02019 (2020 Cohort, followed from March 2020\u00a0at pandemic onset).\u00a0Newly diagnosed patients\u00a0had no glaucoma therapy in the preceding year.\u00a0For the primary persistence analysis, follow-up was restricted to 24\u00a0months to avoid contamination of the 2018 cohort by pandemic exposure.\u00a0Persistence was defined as continuous prescription refills allowing a 90-day grace period. Adherence was measured using the Medication Possession Ratio (MPR), with\u2009\u2265\u200980% defined as adherent. We used Cox proportional hazards models and chi-square tests for comparisons. Among 111,373\u00a0established patients, the risk of discontinuation was significantly higher during the pandemic (adjusted HR 1.17, 95% CI 1.15-1.18; p\u2009<\u20090.001).\u00a0Absolute persistence rates at 12\u00a0months were 89.1% (2018 cohort) vs. 86.7% (2020 cohort); at 24\u00a0months, 72.4% vs. 68.9%.\u00a0This finding was consistent in\u00a0newly diagnosed-only sensitivity analyses (aHR 1.13, 95% CI 1.08-1.18). Among\u00a0newly diagnosed patients, adherence was lower in the\u00a02020 cohort\u00a0(65.1% vs. 68.6%, p\u2009<\u20090.001). New therapy initiations declined by 37% in 2020 (1.0 per thousand at-risk population) compared to 2018 (1.6 per thousand). The pandemic was associated with significant disruptions to glaucoma therapy, including increased discontinuation among\u00a0established patients\u00a0and a marked reduction in new treatment initiations. These findings highlight the vulnerability of daily drop-based regimens to healthcare system disruptions.\u00a0More resilient therapeutic approaches merit further consideration.\n\nID: 42461534\nTitle: A hybrid model for early diagnosis of ophthalmology diseases leveraging CNNs, SBOA optimization, and XAI for visualization.\nAbstract: Ophthalmology diseases are among the leading causes of vision loss worldwide. Glaucoma, diabetic retinopathy, and cataracts are the most common diseases and can lead to permanent vision loss if left untreated. In this paper, a new hybrid model has been proposed with the methods accepted in the literature used in the early diagnosis of these diseases. The relationships between imaging analyses and clinical evaluations performed in the diagnostic processes of glaucoma, diabetic retinopathy, and cataract are discussed, and the methods that help to identify diseases in the early stages are emphasized. In addition, the contributions of advanced technologies and imaging systems used in diagnosing these diseases to the developments in the field of eye health are discussed. This article proposes a hybrid model for eye disease detection that combines Convolutional Neural Networks (CNNs) with a metaheuristic optimization algorithm. This model uses ShuffleNet and ResNet101 models as feature extractors, while the Secretary Bird Optimization Algorithm (SBOA) is used for feature selection. Then, the extracted feature maps were combined with ShuffleNet and ResNet101 and optimized with SBOA. The feature fusion process aimed to improve the performance of the developed model by combining different features of the same image. The combined feature map optimized with SBOA was classified into six different classifiers so that the model could work faster and more effectively. Competitive results were produced in the developed model. Finally, explainable artificial intelligence methods were used to visualize the decisions of the developed hybrid model and understand the internal working principle of the model.\n\nID: 42461304\nTitle: Global, regional, and national burden of glaucoma, 1990-2023: a systematic analysis of the Global Burden of Disease Study 2023.\nAbstract: This study aims to characterize the spatiotemporal trends in the global glaucoma burden from 1990 to 2023 and project future trends to 2050, informing tailored prevention and control strategies across countries. Age-standardized disability-adjusted life-year (AS-DALY) rates for glaucoma were extracted from the Global Burden of Disease Study 2023 database for 204 countries and territories. Temporal trends from 1990 to 2023 were quantified using the estimated annual percentage change (EAPC), and joinpoint regression was applied to identify significant changes in trend, with average annual percentage change (AAPC) used to summarize overall long-term patterns. Future burden from 2024 to 2050 was projected using an exponential smoothing state-space (ETS/EMS) model. Associations between burden and socio-demographic development were assessed using both Pearson and Spearman correlations with the Socio-demographic Index (SDI). An age-period-cohort framework was further used to evaluate age, period, and cohort effects on glaucoma burden. In 2023, the global glaucoma AS-DALY rate was 7.46 per 100,000, reflecting a 39% decline (-\u20094.74 units) since 1990, despite a 52% rise in absolute DALYs due to population aging. Males exhibited a steeper decline (EAPC\u2009-\u20091.58%) than females (-\u20091.25%). High- and middle-SDI countries neared the minimum burden by 2000 and 2010, respectively, while low-SDI countries showed persistent high rates with partial rebounds. The period 2000-2015 accounted for 41% of the total reduction. Forecasts suggest a mean annual AS-DALY decline of 1.2% from 2023 to 2050, yielding a 27.8% reduction without rebound. Glaucoma exhibits a trajectory of rising cases but declining rates, with significant SDI-related disparities. Low-SDI countries require AI-enabled mass screening and access to generic medications, middle-SDI countries need risk-stratified management and laser trabeculoplasty, and high-SDI countries should focus on normal-tension glaucoma in the elderly. WHAT IS KNOWN: \u25cf Glaucoma remains a leading cause of irreversible blindness worldwide, with its burden historically influenced by aging populations and healthcare disparities across regions. \u25cf Despite a 52% increase in absolute DALYs due to aging, the global age-standardized DALY rate for glaucoma fell by 39% from 1990 to 2023, with males experiencing a steeper decline than females. \u25cf Significant inequalities persist: high-and middle-SDI countries approached minimal burden levels years ago, while low-SDI countries continue to face high rates with occasional rebounds. \u25cf Forecasts predict a continued annual decline of 1.2% in age-standardized burden to 2050, and the study provides specific, tailored prevention strategies for countries at different development levels.\n\nID: 42461138\nTitle: Clinical Features and Outcomes in Patients with Acute Retinal Necrosis in Both Eyes at the Time of Initial Presentation - Bilateral Acute Retinal Necrosis (BARN).\nAbstract: To analyze the clinical features and outcomes in patients presenting with Bilateral Acute Retinal Necrosis (BARN) at the time of initial presentation. Retrospective, observational study of patients with bilateral Acute Retinal Necrosis (BARN) at a tertiary care center in South India from 2016 to 2025. Data collected included demographics, systemic and ocular history, BCVA (converted to logMAR for analysis), treatment modalities (medical and surgical), and complications such as retinal detachment, glaucoma, and phthisis bulbi. BARN was noted in 41 patients out of a total of 319 clinical records of ARN (12.8%). One-third patients (36.5%) had a history of HIV. The mean BCVA improved from 1.37 logMAR at presentation to 1.18 logMAR after a mean follow-up of 38.4\u2009months. Rhegmatogenous retinal detachment (RRD) was the most common complication, affecting 36.5% (30/82) of eyes, with 8 eyes presenting with RRD and 22 developing it during follow-up. Exudative retinal detachment was noted in 7 eyes. Other complications included optic atrophy (10.9%), phthisis bulbi (4.8%), glaucoma (2.4%), and epiretinal membrane (1.2%). Medical treatment included antivirals and systemic corticosteroids. Bilateral acute retinal necrosis is uncommon but has more severe course and results in significant ocular complications and poor visual outcomes underscoring the aggressive nature of the disease.\n\nID: 42460345\nTitle: Retinal layer segmentation in OCT images with a 2.5D cross-slice feature fusion module for glaucoma assessment.\nAbstract: For accurate glaucoma diagnosis and monitoring, reliable retinal layer segmentation in OCT images is essential. However, existing 2D segmentation methods often suffer from slice-to-slice inconsistencies due to the lack of contextual information across adjacent B-scans. 3D segmentation methods are better for capturing slice-to-slice context, but they require expensive computational resources. To address these limitations, we propose a 2.5D segmentation framework that incorporates a novel cross-slice feature fusion (CFF) module into a U-Net-like architecture. The CFF module fuses inter-slice features to effectively capture contextual information, enabling consistent boundary detection across slices and improved robustness in noisy regions. The framework was validated on both a clinical dataset and the publicly available DUKE DME dataset. Compared to other segmentation methods without the CFF module, the proposed method achieved an 8.56% reduction in mean absolute distance and a 13.92% reduction in root mean square error, demonstrating improved segmentation accuracy and robustness. Overall, the proposed 2.5D framework balances contextual awareness and computational efficiency, enabling anatomically reliable retinal layer delineation for automated glaucoma evaluation and potential clinical applications.\n\nID: 42460176\nTitle: Myopic Shift Following Clear Lens Extraction in a Patient With Plateau Iris Syndrome Reversed by Synechiolysis: A Case Report.\nAbstract: This case report describes a rare mechanical etiology of postoperative refractive surprise - anterior displacement of an intraocular lens (IOL) secondary to localized posterior synechiae - in a patient with plateau iris syndrome (PIS) following combined clear lens extraction (CLE) and minimally invasive glaucoma surgery (MIGS). A 29-year-old man with PIS and medically refractory chronic angle-closure glaucoma underwent an uneventful left-eye CLE, goniosynechiolysis, implantation of a toric extended depth-of-focus (EDOF) IOL, and insertion of three iStent infinite\u00ae\u00a0(Glaukos Corporation, Aliso Viejo, CA, USA) devices. Five weeks postoperatively, he presented with blurred vision, asthenopia, and binocular diplopia associated with a sudden -2.50 D myopic surprise. Dynamic slit-lamp examination revealed localized posterior synechiae extending from 1 to 5 o'clock. These adhesions exerted asymmetrical traction on the capsular bag, resulting in anterior displacement and temporal tilt of the IOL complex without pupillary block. The patient subsequently underwent targeted synechiolysis under local anesthesia. Postoperative biometry demonstrated an increase in anterior chamber depth (ACD) from 2.90 mm to 3.02 mm, confirming posterior repositioning of the IOL. Restoration of the effective lens position (ELP) reversed the myopic shift and resolved the patient's symptoms. This case highlights localized posterior synechiae as a rare but reversible cause of postoperative refractive surprise and underscores the importance of meticulous dynamic slit-lamp evaluation and ACD monitoring in patients with complex anterior segment conditions presenting with unexpected refractive outcomes. Timely synechiolysis may serve as a definitive and restorative intervention.\n\nID: 42457152\nTitle: Effectiveness of SLT in lowering IOP in steroid-induced glaucoma: a systematic review.\nAbstract: The effectiveness of selective laser trabeculoplasty for steroid-induced glaucoma and steroid-induced ocular hypertension is reviewed. Steroid-induced glaucoma and ocular hypertension often occur in medically complex eyes that may require continued corticosteroid therapy. Selective laser trabeculoplasty may provide intraocular pressure control while reducing dependence on topical glaucoma medications. This systematic review was registered with PROSPERO (CRD420251274498) and conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (or PRISMA) guidelines. Ovid MEDLINE, Embase, and the Cochrane Library were searched from inception to December 28, 2025. Eligible studies included patients with steroid-induced glaucoma or ocular hypertension treated with selective laser trabeculoplasty and reporting intraocular pressure outcomes. Two reviewers independently performed screening, full-text review, data extraction, and Risk Of Bias In Non-randomized Studies of Interventions-I (or ROBINS-I) risk-of-bias assessment. Because of heterogeneity in design, follow-up, and outcome reporting, results were synthesized descriptively. Nine studies comprising 162 eyes were included. Most were retrospective, with sample sizes ranging from 4 to 35 eyes and follow-up from 1 to 24 months. Baseline intraocular pressure ranged from 21.7 \u00b1 0.9 to 38.4 \u00b1 7.3 mm Hg, and final intraocular pressure ranged from 13.3 to 16.1 \u00b1 3.4 mm Hg. Reported intraocular pressure reduction ranged from 27.7% to 59.1%, with sustained effects beyond 12 months in several studies. Seven studies reported a reduced glaucoma medication burden after treatment. No major sight-threatening adverse events were identified. Risk of bias was moderate to serious in most studies. Selective laser trabeculoplasty appears to be a promising and generally safe option for steroid-induced glaucoma and ocular hypertension, but higher-quality prospective comparative studies are needed.\n\nID: 42457149\nTitle: Glaucoma and cognition: a systematic review and meta-analysis of cognitive metrics in glaucoma patients.\nAbstract: To evaluate whether glaucoma is associated with reduced performance on standardized cognitive assessments and to characterize the affected cognitive domains. A systematic review was conducted using MEDLINE, Embase, Cochrane CENTRAL, and Web of Science from inception to March 2026. Eligible studies included adult glaucoma patients assessed with validated cognitive tools. Meta-analysis was performed for the Mini-Mental State Examination (MMSE), with pooled mean differences (MD) calculated using random-effects models. Indirect subgroup comparisons were performed by glaucoma subtype, geography, and age. Narrative synthesis was performed for MoCA and cognitive domain-specific assessments. Twenty-four studies (n\u202f=\u202f16 569) were included. MMSE meta-analysis suggested lower MMSE scores among glaucoma patients compared with controls (MD: -2.85; 95% CI: -3.36 to -2.34; p < .001), although substantial heterogeneity was present (I\u00b2\u202f=\u202f94.5%). Exploratory study stratification suggested greater MMSE reductions in developing countries (MD: -3.79; p < .001) than in developed countries (MD: -0.74; p > .05). Despite lower MMSE performance, scores remained above commonly used thresholds for CI. Narrative synthesis found that MoCA-based studies demonstrated inconsistent findings without a clear difference between glaucoma and comparator groups. Among domain-specific areas, deficits in verbal fluency, visuospatial skills, and memory were suggested. Interpretation of these findings was limited by the visual dependence of cognitive assessments, raising the possibility that visual impairment may reduce scores. Current evidence suggests a hypothesis-generating association that glaucoma may reduce performance on cognitive assessments. However, interpretation is limited by substantial heterogeneity and the visual dependence of cognitive assessments, highlighting the need for standardized, longitudinal studies to better define the scope and mechanisms of this relationship.\n\nID: 42456974\nTitle: Prevalence and severity of undetected open-angle glaucoma in persons 77-89 years old.\nAbstract: To determine the prevalence and severity of previously undetected open-angle glaucoma in individuals 77-89 years of age in Malm\u00f6, Sweden. Cross-sectional study SUBJECTS: All residents of Malm\u00f6, Sweden, aged 77-89 years were eligible for participation, except individuals with a prior glaucoma diagnosis at Sk\u00e5ne University Hospital. A total of 1957 individuals were invited, of whom 602 (30.8%) attended the screening. The screening procedure included intraocular pressure measurement using an Icare tonometer, visual field screening using the Frequency Doubling Technology (FDT) perimeter, and fundus photography. Subjects with positive screening results were offered a post-screening visit with a full ophthalmological examination, including threshold perimetry using the SITA Standard 24-2 program of the Humphrey Field Analyzer. The severity of disease was evaluated based on the perimetric mean deviation (MD) index. Prevalence of previously undetected open-angle glaucoma in individuals 77-89 years old (%) and the magnitude of visual field defects expressed as proportions (%) of patients in 5 different disease severity stages. The prevalence of previously undetected open-angle glaucoma was 5.98% (95% CI: 4.2%-8.2%), n= 35 patients. The condition was unilateral in 74% of patients. The severity of disease was early in 66% and moderate in 20%, while 14% of patients had advanced or severe disease. No patient had developed end-stage disease. The median intraocular pressure in glaucoma patients was 16 mmHg (IQR: 14-19 mmHg). The prevalence of previously undetected open-angle glaucoma was high in this age category, 5.98%, but most patients had early or moderate disease, and no patient had end-stage disease.\n\nID: 42456425\nTitle: Cold exposure and glaucoma with intraocular pressure dysregulation in population and experimental studies.\nAbstract: Extreme cold exposure is an emerging climate-related stressor, but its impact on glaucoma-related outcomes and intraocular pressure (IOP) remains unclear. We conducted an integrated epidemiological and experimental study combining a time-stratified case-crossover analysis of 4090 glaucoma patients in Shanghai with multivariable linear regression and mechanistic experiments. Extreme cold exposure was associated with increased glaucoma outpatient visits, and lower ambient temperature was associated with higher IOP across multiple lag days after adjustment for demographic, meteorological, and air pollution factors. In vivo, chronic cold exposure (4 \u00b0C, 22\u202fh/day, 4 weeks) was associated with sustained IOP elevation and anterior segment changes, accompanied by increased extracellular matrix (ECM) deposition, enhanced trabecular meshwork contractility, and elevated serum glucocorticoid and norepinephrine levels. In vitro, dexamethasone increased \u03b1-smooth muscle actin (\u03b1SMA) and collagen type I alpha 1 chain (COL1A1), while norepinephrine increased myosin regulatory light chain 2 (MLC2) phosphorylation. Transcriptomic analysis identified 5168 differentially expressed genes enriched in ECM organization, TGF-\u03b2 signaling, calcium signaling, and cGMP-PKG pathways. In conclusion, extreme cold exposure was associated with glaucoma-related outcomes and IOP elevation, and integrated evidence suggests that cold-related neuroendocrine activation may contribute to extracellular matrix remodeling and trabecular meshwork dysfunction, potentially affecting aqueous humor outflow and IOP regulation.\n\nID: 42456385\nTitle: Salidroside inhibits extracellular matrix deposition and oxidative stress in human trabecular meshwork cells by suppressing the TNF signaling pathway and upregulating MMP3 expression.\nAbstract: The functional integrity of human trabecular meshwork cells (HTMCs) is essential for regulating intraocular pressure (IOP). In primary open-angle glaucoma (POAG), pathological stimuli induce oxidative damage and promote excessive extracellular matrix (ECM) deposition in HTMCs, thereby hindering aqueous humor outflow. Salidroside (Sal), a compound with diverse pharmacological activities, has been reported to inhibit oxidative stress and reduce ECM accumulation. This study aimed to investigate whether Sal exerts its antioxidant effects by regulating matrix metalloproteinase 3 (MMP3) expression via the TNF signaling pathway. Potential targets of salidroside and glaucoma were predicted using SwissTargetPrediction and GeneCards online databases, and overlapping targets were identified. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed on these intersecting targets. Meanwhile, the glaucoma GEO dataset (GSE27276) was downloaded for differential gene expression analysis, and the results were further compared with the intersecting targets to identify key genes. An oxidative damage model of HTMCs was established using hydrogen peroxide (H\u2082O\u2082) induction. Cell viability was assessed using the MTT assay to determine the appropriate H\u2082O\u2082 concentration for modeling, as well as the safe dosage and treatment duration of Sal. Oxidative stress markers were measured as follows: superoxide dismutase (SOD) and malondialdehyde (MDA) levels were determined by enzyme-linked immunosorbent assay (ELISA), while reactive oxygen species (ROS) levels were assessed using DCFH-DA staining. Furthermore, the expression of ECM proteins such as collagen type I (COL-I), fibronectin (FN), and laminin (LN), as well as MMP3 and TNF signaling pathway-related proteins, was detected by Western blot and immunofluorescence (IF). Rescue experiments were performed using the TNF inhibitor R7050 and the broad-spectrum MMP inhibitor GM6001. In addition, a rat glaucoma model was established by injecting microbeads into the anterior chamber of SD rats. Intraocular pressure changes were monitored using a TonoLab tonometer. Retinal tissue morphology was observed by hematoxylin-eosin (H&E) staining. Retinal ganglion cell apoptosis was detected by TUNEL assay. The expression of oxidative stress markers and ECM-related proteins in the retina and serum was measured by Western blot and ELISA. A total of 68 intersecting targets were identified from the database analyses. Enrichment analysis indicated that these targets were primarily involved in biological processes such as oxidative stress and ECM regulation, as well as the TNF signaling pathway. Experimental results further demonstrated that Sal significantly increased the viability of H\u2082O\u2082-damaged HTMCs and effectively inhibited intracellular oxidative stress and ECM protein expression. Moreover, the TNF signaling pathway inhibitor R7050 enhanced the inhibitory effects of Sal on oxidative stress and ECM deposition in HTMCs. Screening of the GEO database identified MMP3 as a key gene. Western blot results showed that Sal upregulated MMP3 expression in H\u2082O\u2082-treated HTMCs. Furthermore, the MMP3 inhibitor GM6001 reversed the protective effects of Sal against oxidative stress and ECM deposition. Interestingly, in the presence of Sal, co-treatment with R7050 and GM6001 revealed that GM6001 reversed the effects of R7050 on oxidative stress and ECM, suggesting that Sal may act through the TNF/MMP3 axis. In vivo experiments further confirmed that Sal effectively reduced IOP in glaucomatous rats, alleviated retinal pathology, and significantly decreased oxidative stress levels and ECM deposition. Sal, both in vitro and in vivo, promotes MMP3 expression by inhibiting the activation of the TNF signaling pathway, thereby suppressing ECM deposition and mitigating oxidative damage in trabecular meshwork cells.\n\nID: 42455350\nTitle: [Experiences of glaucoma patients : Evaluation of the survey conducted by the Federal Association Glaucoma Self-help and the DOG Glaucoma Section].\nAbstract: Glaucoma is one of the most frequent causes of blindness worldwide, including in Germany; however, it is unclear whether all those affected are sufficiently informed about their condition, possible treatment and their side effects. Survey of glaucoma patients to assess the level of awareness about the disease and its treatment. The questionnaire consisted of 11\u00a0specific questions that asked about education and satisfaction with treatment for glaucoma. It was developed by the Federal Association Glaucoma Self-help (Bundesverband Glaukom-Selbsthilfe e.\u202fV). in collaboration with the Glaucoma Section of the German Society of Ophthalmology (DOG) and made available to members of the association as well via the website and patient forums and in waiting rooms. A total of 334 glaucoma patients participated in the survey between July 2024 and June 2025. Of the respondents 15.5% stated that they were very well informed, while 40.1% reported they had been inadequately informed. There was a\u00a0lack of information on treatment options and side effects as well as on the prescribed eye drops. Patients therefore sought alternative sources of information (e.g., the internet). Results were also mixed when it came to information about treatment use and side effects and 89.5% said they knew how to use their treatment. Approximately 50% were able to discuss changes to their treatment or information about alternative treatments with their doctor. The findings from this survey should be used to develop more targeted patient education strategies in the future. Patient-centered understandable and continuous education should be a\u00a0central component of treatment. This would contribute to improved adherence and thus also to the quality of life of those affected. HINTERGRUND: Das Glaukom ist eine der h\u00e4ufigsten Erblindungsursachen weltweit, so auch in Deutschland. Dennoch ist unklar, ob alle Betroffenen ausreichend \u00fcber ihre Erkrankung sowie m\u00f6gliche Therapien und deren Nebenwirkungen informiert sind. Umfrage unter GlaukompatientInnen, um den Stand der Aufkl\u00e4rung \u00fcber die Erkrankung und m\u00f6gliche Therapien zu erfassen. Der Fragenbogen bestand aus 11\u00a0Fragen zur Aufkl\u00e4rung und Therapiezufriedenheit bez\u00fcglich des Glaukoms. Er wurde vom Bundesverband Glaukom-Selbsthilfe e.\u202fV. in Zusammenarbeit mit der Sektion Glaukom der Deutschen Ophthalmologischen Gesellschaft (DOG) entwickelt. Der Fragebogen wurde den Mitgliedern des Bundesverbandes sowie \u00fcber die Homepage und Patientenforen zug\u00e4nglich gemacht und in Wartezimmern ausgelegt. Es nahmen 334 GlaukompatientInnen von Juli 2024 bis Juni 2025 an der Umfrage teil; 15,5\u202f% der Befragten gaben an sehr gut aufgekl\u00e4rt zu sein, 40,1\u202f% gaben an, dass sie unzureichend aufgekl\u00e4rt wurden. Es fehlten Informationen zu Therapieoptionen und Nebenwirkungen sowie zu den verschriebenen Tropfen. Daher suchten PatientInnen nach alternativen Informationsquellen (z.\u202fB. Internet). Auch bei der Aufkl\u00e4rung \u00fcber die Therapieanwendung und Nebenwirkungen zeigten sich heterogene Ergebnisse; 89,5\u202f% gaben an zu wissen, wie sie ihre Therapie anwenden m\u00fcssen. \u00c4nderung der Therapie oder Informationen zu alternativen Therapien konnten ca.\u00a050\u202f% der Teilnehmenden mit ihrem Arzt besprechen. Durch die Erkenntnisse aus dieser Umfrage sollen zuk\u00fcnftig gezieltere Aufkl\u00e4rungsstrategien entwickelt werden. Eine patientenzentrierte, verst\u00e4ndliche sowie kontinuierliche Aufkl\u00e4rung sollte ein zentraler Bestandteil der Therapie sein. Dies w\u00fcrde zu einer Verbesserung der Adh\u00e4renz und somit auch der Lebensqualit\u00e4t der Betroffenen beitragen.\n\nID: 42455251\nTitle: Nonpenetrating Deep Sclerectomy versus Conventional Surgery in Primary Congenital Glaucoma: a Systematic Review and Meta-analysis.\nAbstract: Primary congenital glaucoma (PCG) is a leading cause of irreversible childhood blindness, with elevated prevalence in consanguineous populations of the Middle East and Central Asia. Nonpenetrating deep sclerectomy (NPDS) is theoretically safer than conventional penetrating surgery, yet comparative evidence lacks systematic synthesis. We systematically searched seven databases through December 2025. Eligible studies compared NPDS with conventional surgery in children with PCG aged under 4 years with\u2009\u2265\u20096\u00a0months follow-up. Two reviewers independently screened and extracted data; risk of bias was assessed with ROBINS-I and RoB 2.0. A random-effects meta-analysis [REML with Hartung-Knapp-Sidik-Jonkman (HKSJ) correction] was performed. Five studies [seven arms, 356 eyes; one randomized controlled trial (RCT), four observational] were included. Mean intraocular pressure (IOP) reduction was 10.34\u00a0mmHg (HKSJ 95% CI 7.54-13.14; 95% PI: 2.25-18.43\u00a0mmHg; I2\u2009=\u200997.2%, indicating substantial between-study variability driven primarily by differences in baseline IOP [\u03b2\u2009= +0.61\u00a0mmHg; P\u2009=\u20090.004], adjuvant use, and surgical technique; P\u2009<\u20090.001). Surgical success was achieved in 77.1% of eyes (95% CI 65.3-85.8%). Visual acuity improved by 0.329 LogMAR (approximately three Snellen lines; 95% CI 0.220-0.438; P\u2009=\u20090.001). The composite complication rate was 13.2% (95% CI 8.7-19.4%), with I2\u2009=\u20090% for hypotony, shallow anterior chamber, and hyphema. NPDS resulted in significantly fewer reinterventions (7.4% versus 14.1%; P\u2009=\u20090.046) and better corneal clarity preservation (92.4% versus 83.4%; P\u2009=\u20090.013) than non-NPDS procedures. Evidence comparing NPDS and conventional surgery in PCG remains limited. Surgery achieved a mean IOP reduction of 10.34\u00a0mmHg (HKSJ 95% CI 7.54-13.14), though estimates showed substantial heterogeneity (I2\u2009=\u200997.2%). While NPDS may be associated with lower reintervention rates and improved corneal clarity, no definitive differences in primary efficacy were observed. These findings require confirmation in well-designed prospective studies. PROSPERO registration: CRD420251121650. Primary congenital glaucoma damages the optic nerve from birth by obstructing aqueous outflow, and surgery, not medication, is the only way to prevent blindness. Standard operations (trabeculotomy, trabeculectomy) create a drainage channel by cutting through the full thickness of the ocular wall, whereas nonpenetrating deep sclerectomy (NPDS) dissects to the inner trabecular layer without breaching it, with the theoretical benefit of avoiding sudden postoperative hypotony and reducing lifetime infection risk. Whether this anatomical compromise preserves efficacy was the question we set out to answer. Searching seven databases through December 2025, we identified five comparative studies involving 356 eyes across four countries, all with at least 6 months\u2019 follow-up. Pooled analysis showed a mean intraocular pressure (IOP) reduction of 10.34\u00a0mmHg (95% CI 7.54\u201313.14), surgical success in 77% of eyes, and a mean visual acuity improvement of 0.33 LogMAR. The results are broadly comparable to conventional surgery, yet interstudy heterogeneity was extreme (I2\u2009=\u200997.2%), driven more by differences in baseline IOP, adjuvant mitomycin use, and surgeon experience than by anything intrinsic to the technique itself. The evidence has real limits: only one randomized trial was found, two studies carried serious risk of bias, and success was defined differently across centers. NPDS appears effective and safe. Whether it is better than conventional surgery, or in which patients it should be preferred, remains genuinely open. Answering that will require larger randomized trials with standardized outcome criteria.\n\nID: 42454820\nTitle: The impact of trabeculotomy degree on surgical success in gonioscopy-assisted transluminal trabeculotomy surgery.\nAbstract: To evaluate the impact of varying degrees of trabeculotomy during gonioscopy-assisted transluminal trabeculotomy surgery on postoperative intraocular pressure reduction and surgical success. Patients who underwent gonioscopy-assisted transluminal trabeculotomy (at least 90\u00b0) for open-angle glaucoma and had a follow-up period of at least 12 months were included. Patients were grouped according to trabeculotomy degree (Group 1: 90\u00b0<\u03b8\u2264180\u00b0; Group 2: 180\u00b0<\u03b8<360\u00b0; Group 3: \u03b8=360\u00b0). Ophthalmic examination findings, intraocular pressure measurements, number of antiglaucoma medications, and complications were recorded. Surgical success was defined as intraocular pressure <15 mmHg with at least a 20% reduction; surgical failure was defined as failure to meet this criterion or the need for additional surgery. A total of 100 patients were included: 20 in Group 1, 24 in Group 2, and 56 in Group 3. Intraocular pressure levels differed significantly only in the first postoperative month (p=0.013). At 12 months, intraocular pressure levels, percentage reduction in intraocular pressure, and mean number of antiglaucoma medications did not differ significantly (p>0.05). No correlation was found between trabeculotomy degree and percentage intraocular pressure reduction (p=0.173). At 12 months, surgical success rates were similar (60.0%, 58.3%, and 64.3% for Groups 1, 2, and 3, respectively). Complication rates were also comparable among the groups. The degree of trabeculotomy did not affect surgical success over a 12-month follow-up period. Although early intraocular pressure reduction may differ with 360\u00b0 trabeculotomy, a complete 360\u00b0 incision may not be necessary to achieve optimal pressure reduction.\n\nID: 42454819\nTitle: Evaluation of diode laser cyclophotocoagulation efficiency in refractory glaucoma and determination of structural changes using ultrasound biomicroscopy.\nAbstract: To evaluate the effect of single-session transscleral diode laser cyclophotocoagulation on intraocular pressure in refractory glaucoma and to determine structural changes using ultrasound biomicroscopy. Forty-three eyes were evaluated. Intraocular pressures at baseline and at the first, third, and sixth months after transscleral diode laser cyclophotocoagulation were compared. Ciliary body thickness, ciliary muscle thickness, ciliary process thickness, iris root thickness, and scleral thickness were assessed at baseline and at the third and sixth months post-treatment. Reductions in intraocular pressure were significant between baseline and the first month (p=0.018), third month (p<0.001), and sixth month (p<0.001) as well as between the first and third months (p=0.034) and the first and sixth months (p=0.036). Compared with baseline, intraocular pressure reduction rates at the first, third, and sixth months were 34.6%, 56.5%, and 55.3%, respectively, while success rates were 30.2%, 62.8%, and 55.8%, respectively. Decreases in ciliary body thickness, ciliary muscle thickness, and ciliary process thickness were significant between baseline and the third month (p<0.05) and between baseline and the sixth month (p<0.05), whereas changes between the third and sixth months were not significant (p>0.05). Iris root and scleral thicknesses did not change after treatment (p>0.05). At the third and sixth months, significant positive correlations were observed between changes in intraocular pressure and changes in ciliary body thickness and ciliary process thickness (p<0.05). To the best of our knowledge, this is one of the few studies comprehensively investigating structural changes after transscleral diode laser cyclophotocoagulation using ultrasound biomicroscopy. Moreover, the relationships between intraocular pressure changes and variations in the ciliary body, ciliary muscle, ciliary process, iris root, and scleral thicknesses were examined in detail. Single-session treatment did not affect iris root or scleral thickness but significantly reduced ciliary body, ciliary muscle, and ciliary process thicknesses. Greater reductions in ciliary body and ciliary process thickness may contribute to more pronounced intraocular pressure reduction.\n\nID: 42454727\nTitle: Beyond Acute Cytotoxicity: A Repair-Exhaustion Framework for Chronic Sublethal Benzalkonium Chloride Toxicity in Repeated Ophthalmic Exposure.\nAbstract: Benzalkonium chloride (BAK), a common preservative in multi-dose ophthalmic products, is often studied under acute high-dose exposure, which highlights overt damage to corneal epithelial cells. These studies tend to exaggerate the maximum cytotoxic effects and do not accurately reflect the gradual, cumulative damage seen during long-term use. By reviewing clinical, animal, and cellular data, we argue that repeated low-dose BAK exposure leads to barrier dysfunction, energy depletion, priming of inflammation, and impaired regeneration before significant cell death occurs. We suggest a repair-exhaustion model: minor injuries from repeated exposure are initially managed by membrane resealing and epithelial renewal, but over time, repair capacity becomes exhausted. This has two main implications: (i) long-term toxicity should be evaluated using functional measures such as barrier integrity, mitochondrial health, inflammation, and repair ability, and not cell viability alone; (ii) there may be a window during which reducing preservative levels or adding barrier-supporting and mitochondrial-protective agents can minimize cumulative damage. Instead of simply using or avoiding the preservative, this approach encourages formulation and clinical strategies that maintain antimicrobial effects while strengthening tissue resilience.\n\nID: 42454630\nTitle: Finite Element Modeling of Aqueous Outflow and Trabeculotomy in Glaucomatous Eyes With Resistive and Segmented Schlemm's Canal.\nAbstract: A novel open-angle glaucoma treatment procedure, femtosecond laser image-guided high-precision trabeculotomy (FLIGHT), non-invasively creates aqueous humor (AH) drainage channels from the anterior chamber (AC) to Schlemm's canal (SC) through the trabecular meshwork (TM). The channels decrease AH outflow resistance, thus decreasing intraocular pressure (IOP). The effect of the procedure greatly depends on the condition of the SC segment where the drainage channel ends. The purpose of this study was to develop a 3D finite element model (FEM) of the FLIGHT procedure in the case of resistive flow of the AH in the SC, including cases of segmental flow resulting from blocked or collapsed segments of the SC. We adopted the 3D FEM of the intact glaucomatous eye, including drainage system parameters, from our previous paper to simulate the FLIGHT treatment in eyes with resistive and segmental flow in the SC. The TM, SC and collector channels (CCs) were modeled as porous materials, with assigned permeability, to approximate the outflow resistance found in these tissues in-vivo. The permeability of segments of the SC was varied to model resistive and segmental flow within the SC. The FLIGHT treatment was simulated by removing block-like pieces of the TM to create channels that connected the AC to the SC. The size and locations of collapsed segments of SC in the FEM were varied to investigate their impact on IOP reduction following simulated FLIGHT. The FEM simulation results showed that the IOP reduction was maximized when FLIGHT drainage channels were in \"free flow\" segments of SC. Conversely, channels connecting the AC to blocked or collapsed regions of SC had a significantly diminished effect on IOP reduction. However, this was mitigated by replacing a single drainage channel with multiple channels that bypass the TM in different locations, including \"free flow\" segments. The condition of SC distal to the FLIGHT drainage channels has a significant influence on IOP reduction. The importance of multiple drainage channels targeting more segments of the SC is highlighted to mitigate the effect of collapsed segments of the SC.\n\nID: 42454570\nTitle: A previously uncharacterized R881S variant of transporter NBCe1 exhibits intracellular retention and virtually no plasma membrane expression.\nAbstract: Mutations in the Na+/HCO3- cotransporter NBCe1 (SLC4A4) cause proximal renal tubular acidosis (pRTA) and extrarenal symptoms including glaucoma, band kelatopathy, migraine, growth disorder, and abnormal tooth enamel. From NCBI dbSNP database, we recently identified a previously uncharacterized single nucleotide variant (SNV) R881S in NBCe1, located in hydrophilic helix 4. R881S NBCe1-A showed intracellular retention in human embryonic kidney 293 cells and its plasma membrane expression was profoundly reduced in polarized Madin-Darby canine kidney cells. Unlike WT and R881C NBCe1-A (which causes pRTA), Western blot analysis demonstrated that the R881S NBCe1-A showed a single, low-molecular-weight signal at above 100kDa. Deglycosylation study showed that R881S NBCe1-A was scarcely deglycosylated by PNGase F. Coimmunoprecipitation study demonstrated that wild-type and R881S NBCe1-A did not form heterodimer. Moreover, functional analysis using Xenopus oocytes revealed that the R881S variant had markedly reduced transport activity compared with wild-type NBCe1-A. Thus, R881S NBCe1-A shows no detectable transport activity, likely due to defective trafficking and reduced glycosylation. In contrast to the R881C mutant, however, R881S NBCe1-A fails to form dimers with wild-type NBCe1-A, suggesting the absence of a dominant-negative effect and underscoring the need for functional characterization of reported genetic variants.\n\nID: 42454273\nTitle: One-Year Outcome of PreserFlo MicroShunt Implantation in Patients with Open Angle Glaucoma: Real-World Data from a Tertiary Centre.\nAbstract: To evaluate the one-year clinical outcomes, safety profile, and surgical success of the PreserFlo\u00ae MicroShunt in patients with glaucoma treated at a tertiary referral centre in Malaysia. This retrospective study included\u00a040 eyes of 31 patients\u00a0undergoing PreserFlo MicroShunt implantation performed by two experienced surgeons using a standard ab-externo technique with mitomycin C (0.04% for 3\u00a0minutes) and a structured postoperative corticosteroid tapering regimen. Outcomes assessed at 12 months included intraocular pressure (IOP), number of topical glaucoma medications, visual acuity, optic nerve and retinal nerve fibre layer parameters, visual field indices, complications, and surgical success.\u00a0Complete success\u00a0was defined as achieving target IOP without medications, while\u00a0qualified success\u00a0allowed adjunctive medications. Mean IOP was reduced from a preoperative median of 19.0 mmHg to 11.5 mmHg at 12 months\u00a0(p < 0.001). The median number of glaucoma medications decreased from 3.8 to 0.2 drops. At one-year,\u00a0complete surgical success was achieved in 82.5% of eyes, while\u00a0qualified success was 95.0%. Surgical failure occurred in\u00a05.0%\u00a0of eyes. Early postoperative hypotony (IOP \u22645 mmHg) occurred in\u00a017.5%, with persistent hypotony at one year in\u00a02.5%, none of which resulted in vision loss. No cases of sight-threatening complications such as endophthalmitis, corneal decompensation, or loss of light perception were observed. Structural and functional glaucoma parameters remained stable over the follow-up period. Postoperative interventions were required in a proportion of eyes during follow-up. PreserFlo MicroShunt implantation was associated with reductions in IOP and glaucoma medication burden at one year, with generally acceptable short-term safety outcomes. These findings support its role as an effective bleb-forming minimally invasive glaucoma surgery option for patients requiring lower target IOPs, including those with advanced glaucoma. However, the results should be interpreted in the context of the modest sample size, retrospective design, absence of a comparator group, and need for postoperative interventions. This study provides\u00a0the first Malaysian real-world data\u00a0on PreserFlo MicroShunt outcomes and adds to the growing regional evidence base for its use.\n\nID: 42454166\nTitle: Septic Endophthalmitis Following Suprachoroidal Cyclosporine Implant Placement in Two Horses With Equine Recurrent Uveitis.\nAbstract: This article presents the clinical and histopathological findings from two horses that developed severe postoperative complications following suprachoroidal procedures routinely employed in the management of equine recurrent uveitis (ERU). Case 1 was a 5-year-old warmblood stallion that initially received a unilateral suprachoroidal triamcinolone injection, followed later by bilateral suprachoroidal cyclosporine implant (CSI) placement. At 9 weeks postoperatively, the right eye (which had undergone both procedures) developed secondary glaucoma necessitating enucleation. Case 2 was a 14-year-old Appaloosa mare that presented 9 days postoperatively with suspected bilateral CSI rejection. Due to poor visual prognosis, the horse was euthanized. Histopathologic examination of all three affected globes demonstrated findings consistent with severe, suppurative endophthalmitis of bacterial etiology.\n\nID: 42454026\nTitle: Endophthalmitis in XEN45 Gel Stent: Case report and review of the literature.\nAbstract: This is a care of endophthalmitis following XEN45 Gel Stent implantation managed with combined corneal transplant and pars plana vitrectomy, and to review reported cases of endophthalmitis after minimally invasive glaucoma surgery. A 67-year-old male with primary open-angle glaucoma developed endophthalmitis 2\u2009months after XEN45 implantation. Upon referral to our tertiary care center, he underwent urgent implant removal, penetrating keratoplasty with temporary keratoprosthesis, and pars plana vitrectomy with intravitreal antibiotics. Cultures grew Streptococcus gordonii. A second corneal transplant with fresh donor tissue was performed 4\u2009months later. Despite vision limited to light perception, the infection resolved and the eye was preserved. This is the first reported case of XEN45 Gel Stent-associated endophthalmitis which was successfully controlled with combined keratoplasty and vitrectomy. Our review of published cases identified 45 minimally invasive glaucoma surgery-related endophthalmitis cases, with XEN45 accounting for 58%. Potential risk factors included the XEN45 stent's susceptibility to exposure after conjunctival erosion, pool water exposure, and ab externo insertion during implantation. In cases of XEN45 Gel Stent-associated endophthalmitis, corneal transplant with pars plana vitrectomy could be a successful strategy to control infection and spare the globe.\n\nID: 42453935\nTitle: Cataract as an Endpoint-Dependent Confounder in Trials of Neuroprotective Therapies for Glaucoma [Letter].\nAbstract: \n\nID: 42453098\nTitle: Cutaneous laser treatment of port-wine stains and its impact on ocular manifestations in Sturge-Weber syndrome.\nAbstract: Sturge-Weber Syndrome (SWS) is a rare neurocutaneous disorder characterized by the presence of port-wine stains (PWS) and ophthalmologic complications, including glaucoma and choroidal hemangiomas. These manifestations result from somatic mutations in the GNAQ gene, leading to vascular malformations that affect both the skin and ocular tissues. This review aims to evaluate the impact of laser treatment for PWS on ocular manifestations in SWS, considering both clinical outcomes and underlying biological mechanisms. PWS are common in SWS patients and significantly impair quality of life (QoL) and necessitate effective treatment strategies. Pulsed dye laser (PDL) therapy, which targets the abnormal blood vessels within PWS, has been established as an effective method for reducing the size and appearance of these stains. Clinical studies suggest that PDL therapy not only improves dermatologic outcomes but may also have possible association with ocular vascular dynamics such as reducing intraocular pressure and ameliorating choroidal hemangiomas. The review evaluates data from various studies and highlights changes in intraocular pressure, the incidence of glaucoma, and modifications in choroidal hemangiomas following laser treatment. Mechanistic insights suggest that laser therapy may improve dermatologic and ocular symptoms by modulating sebaceous gland activity and enhancing the skin's barrier function, thereby indirectly affecting ocular health. Additionally, the review discusses the safety profiles of different laser systems, the importance of multidisciplinary care, and the need for standardized treatment protocols to minimize risks and optimize patient outcomes. Integrated dermatologic and ophthalmologic care remains crucial in improving the overall health and QoL for patients with SWS.\n\nID: 42452675\nTitle: The Pathophysiological Association Between Obstructive Sleep Apnea and Glaucoma: A Current Update.\nAbstract: Glaucoma is a chronic, progressive optic neuropathy and the second leading cause of irreversible blindness worldwide. Although elevated intraocular pressure (IOP) remains the principal modifiable risk factor, it is neither necessary nor sufficient for disease development. The literature indicates that systemic conditions such as obstructive sleep apnea (OSA) may contribute to its pathogenesis. The pathophysiology of glaucoma is supported by several theories, primarily the mechanical and vascular theories. This review describes the pathophysiological links between OSA and glaucoma considering current theories. The principal connecting mechanism appears to be chronic intermittent hypoxia and reduced ocular perfusion pressure, which trigger optic nerve head hypoxia, oxidative stress, and biomechanical remodeling of the lamina cribrosa. These processes interact within a vicious cycle that progressively compromises the metabolic support of optic nerve axons. The mechanisms described are particularly relevant to normal-tension glaucoma, which may be associated with OSA. Retinal nerve fiber layer thinning appears among the earliest markers of optic nerve vulnerability, whereas IOP and visual field changes are more variable. These observations underscore the clinical relevance of the OSA-glaucoma relationship and support a multidisciplinary approach incorporating routine ophthalmic screening for subclinical optic nerve damage.\n\nID: 42452663\nTitle: Association of Comprehensive Geriatric Assessment with Knowledge- and Technique-Related Eye Drop Adherence Problems in Glaucoma Assessed Using the Shimane University Glaucoma Eye Drop Adherence Questionnaire.\nAbstract: Background/Objectives: Glaucoma medication adherence is influenced by multiple factors, including treatment-related knowledge, eye drop instillation technique, cognitive function, and systemic health status. However, the relationships between comprehensive geriatric assessment (CGA) results and specific adherence-related problems remain poorly understood. This study investigated the associations between CGA results and glaucoma eye drop adherence-related problems using the newly developed Shimane University Glaucoma Eye Drop Adherence Questionnaire (SU-GAQ). Methods: This retrospective study included 187 consecutive glaucoma patients who underwent CGA and completed the SU-GAQ at Shimane University Hospital. The SU-GAQ consists of Knowledge (Q1-Q5) and Technique (Q6-Q15) domains. CGA included the Mini-Cog, G8, and Age-Adjusted Charlson Comorbidity Index (ACCI). Associations between questionnaire responses and CGA results were evaluated using Spearman's rank correlation and generalized regression analyses. Exploratory factor analysis (EFA) based on tetrachoric correlations was performed to evaluate the questionnaire structure. Results: Lower Mini-Cog scores were significantly associated with higher Knowledge-domain scores (\u03c1 = -0.27, p = 0.0002) and higher overall questionnaire scores (\u03c1 = -0.23, p = 0.002). In multivariate analysis, Mini-Cog remained independently associated with the Knowledge domain (estimate = -0.31, p < 0.0001) and total score (estimate = -0.44, p = 0.002). Higher ACCI scores were associated with higher Technique-domain scores (\u03c1 = 0.19, p = 0.009) and remained significant in multivariate analysis (estimate = 0.16, p = 0.02). G8 scores were not significantly associated with questionnaire outcomes. EFA identified a two-factor structure corresponding to the predefined Knowledge and Technique domains, accounting for 71.2% of the total variance. Conclusions: Lower cognitive function was primarily associated with knowledge-related barriers to glaucoma medication adherence, whereas greater comorbidity burden was associated with technical difficulties in eye drop instillation. The SU-GAQ demonstrated a clinically meaningful two-domain structure and may facilitate identification of specific adherence-related barriers in glaucoma patients.\n\nID: 42452571\nTitle: Impact of Lens Thickness on Outcomes After Cataract Versus Combined Cataract-Glaucoma Surgery in a Predominantly Black Population.\nAbstract: Background/Objectives: We aimed to evaluate the relationship between lens thickness (LT) and postoperative outcomes following cataract surgery versus combined cataract-glaucoma procedures in a predominantly Black and Caribbean population, and to assess the utility of LT and the Laroche Glaucoma Risk Calculator in predicting intraocular pressure (IOP) reduction. Methods: This retrospective cohort study included 187 eyes from patients aged \u226550 years that underwent cataract surgery alone or combined cataract-glaucoma surgery (goniotomy or Ahmed retrobulbar/intraconal tube) at a single center in Queens, New York. Preoperative and \u22653-month postoperative data included IOP, visual acuity (logMAR), medication burden, visual field mean deviation, and anterior segment biometry. Patients were stratified by surgical type, diagnosis, and glaucoma risk. Associations between LT and postoperative IOP reduction were analyzed. Results: Mean LT was 4.53 mm. Greater LT was associated with increased postoperative IOP reduction across all groups. Eyes with LT \u22654.5 mm showed greater IOP reduction compared to LT \u22644.2 mm (2.63 vs. 1.19 mmHg). Combined procedures yielded greater IOP reduction than cataract surgery alone, with the largest decrease in the Ahmed group (-4.56 mmHg). Cataract surgery alone produced smaller but significant reductions (-1.58 mmHg) and the greatest visual acuity improvement. Medication burden decreased substantially in the combined groups. Patients with angle-closure glaucoma had the highest LT. High-risk patients demonstrated greater IOP reduction than low-risk patients. Conclusions: Increased LT may serve as a predictive biomarker for postoperative IOP reduction. Incorporating LT and the Laroche Glaucoma Risk Calculator into preoperative planning may enhance surgical decision-making and outcomes, particularly in underserved populations.\n\nID: 42452537\nTitle: Five-Year Outcomes of First-Generation iStent Versus Hydrus Microstent Implantation Combined with Phacoemulsification in Patients with Open-Angle Glaucoma: A Prospective Non-Randomized Comparative Study.\nAbstract: Background: This study assessed the 5-year clinical outcomes of phacoemulsification combined with implantation of either the first-generation iStent Trabecular Micro-Bypass or the Hydrus Microstent in eyes with open-angle glaucoma. Methods: In this prospective, non-randomized comparative study, 65 eyes of 65 patients underwent combined cataract and micro-invasive glaucoma surgery with either iStent or Hydrus implantation. Intraocular pressure (IOP), number of glaucoma medications, best-corrected visual acuity (BCVA), surgical success, postoperative complications, and subsequent glaucoma procedures were analyzed over a 60-month follow-up. Results: At 60 months, outcome data were available for 47 eyes (72.3%), including 25 eyes in the iStent group and 22 eyes in the Hydrus group. Baseline characteristics did not differ significantly between groups. Mean IOP at 60 months was similar after iStent and Hydrus implantation (16.7 \u00b1 1.8 mmHg vs. 16.5 \u00b1 1.9 mmHg, respectively). The mean number of glaucoma medications decreased from 1.86 \u00b1 0.94 to 1.36 \u00b1 1.08 in the iStent group and from 1.60 \u00b1 0.72 to 0.36 \u00b1 0.49 in the Hydrus group, with significantly fewer medications required after Hydrus implantation at 60 months. Medication-free complete surgical success using the IOP \u2264 18 mmHg criterion was achieved in 20.0% of iStent-treated eyes and 63.6% of Hydrus-treated eyes. No eye underwent additional glaucoma surgery or selective laser trabeculoplasty during follow-up. Conclusions: In this prospective non-randomized comparative cohort, both procedures provided comparable long-term treated IOP control when combined with phacoemulsification. Hydrus implantation was associated with a greater medication-sparing effect and a higher proportion of medication-free complete surgical success at 5 years; however, these findings should be interpreted in the context of the non-randomized design and available-case follow-up.\n\nID: 42452492\nTitle: Nose-to-Eye Delivery: The Potential of Intranasal Administration in Ophthalmology.\nAbstract: Non-invasive drug delivery for ocular diseases remains a significant challenge in ophthalmology, as conventional eye drops offer less than 5% bioavailability due to pre-corneal barriers and the corneal epithelium. This review explores the intranasal (IN) route as a promising strategy for targeting both the anterior and posterior segments of the eye. The IN route leverages several distinct pathways: the nasolacrimal reflex for remote physiological stimulation; the \"neural bridge\" through the cribriform plate, allowing direct perineural and vascular transport via the olfactory and trigeminal nerves to bypass the blood-retinal barrier; and systemic absorption that avoids hepatic first-pass metabolism. Pre-clinical evidence indicates that IN administration of agents such as erythropoietin, nerve growth factor, and insulin achieves superior retinal concentrations compared to topical or systemic dosing, offering neuroprotection in models of retinal degeneration and glaucoma. Clinically, varenicline nasal spray is already FDA-approved for dry eye disease, while intranasal steroids demonstrate a favorable ocular safety profile without significantly increasing intraocular pressure. Although limited by mucociliary clearance and small delivery volumes, the IN route offers a painless, non-invasive alternative to intraocular injections, potentially enhancing patient compliance. Future advancements in mucoadhesive nanocarriers are essential to optimize drug residence time and realize the full potential of nose-to-eye delivery in chronic ophthalmic care.\n\nID: 42450538\nTitle: The Interaction Between Insulin Resistance and Neuroinflammation in the Brain and Its Impact on Diabetic Encephalopathy.\nAbstract: Diabetic encephalopathy (DE) is a severe complication of diabetes mellitus affecting the central nervous system (CNS), characterized by cognitive dysfunction. This review systematically explores how the interplay between brain insulin resistance (BIR) and neuroinflammation contributes to the pathogenesis of DE. BIR refers to the diminished responsiveness of the CNS to insulin signaling, resulting in the suppression of the PI3K/Akt and MAPK pathways, impaired glucose metabolism, and dysfunction across multiple neural cell types-including neurons, astrocytes, microglia, brain endothelial cells, and oligodendrocytes. These disturbances manifest as impaired energy metabolism, compromised synaptic plasticity, disruption of the blood-brain barrier, and reduced myelination. Importantly, BIR and neuroinflammation form a vicious cycle within these cells, mutually exacerbating each other and jointly driving the pathological progression of DE. Finally, we have compiled a list of currently available drugs that can improve BIR and suppress neuroinflammation, along with the latest progress in clinical trials, to provide new insights for the future of precision treatment for DE.\n\nID: 42450158\nTitle: Mirvetuximab Soravtansine in the Treatment of Chemotherapy-Resistant Ovarian Cancer: A Systematic Review.\nAbstract: Ovarian cancer is a major cause of gynecological cancer mortality, frequently associated with platinum-resistant recurrences. Given the limited efficacy of conventional chemotherapy in this setting, alternative targeted therapeutics are needed. Mirvetuximab soravtansine (MIRV) is an antibody-drug conjugate designed to deliver the cytotoxic maytansinoid DM4 to folate receptor alpha (FR\u03b1)-overexpressing cells. This systematic review of PubMed, ClinicalKey, and SpringerLink databases (2019-2026) evaluates five publications across three clinical trials (one phase II, two phase III) encompassing 925 patients with platinum-resistant disease. Notably, the phase III MIRASOL trial demonstrated improved survival outcomes with MIRV over standard chemotherapy, extending median overall survival (16.46 vs. 12.75 months; HR 0.67) and progression-free survival (5.62 vs. 3.98 months; HR 0.65), with an objective response rate (ORR) of 42.3% versus 15.9%. Furthermore, the single-arm phase II SORAYA trial reported an ORR of 32.4% in pretreated patients, including those with prior PARP inhibitor and bevacizumab exposure. Although the preceding FORWARD I trial missed its primary endpoint in the unselected population, its high-FR\u03b1 subgroup analysis revealed a clinical benefit that influenced subsequent biomarker-driven enrollment strategies. From a safety perspective, MIRV exhibited lower rates of severe neutropenia and anemia than chemotherapy, with toxicities primarily consisting of manageable, reversible ocular events. Ultimately, MIRV serves as a therapeutic option for platinum-resistant, FR\u03b1-positive ovarian cancer, offering survival advantages; however, rigorous biomarker-based screening remains necessary to optimize therapeutic outcomes.\n\nID: 42449848\nTitle: Conjunctival Vascular Metrics Using Automated Vessel Detection from Slit Lamp Images for Hyperemia Severity Assessment.\nAbstract: Background/Objectives: Conjunctival hyperemia is a common clinical finding in clinical practice; however there are significant differences between graders. Vessel detection using deep-learning approaches could enable more objective measures. We aimed to evaluate vascular metrics derived from automated vessel detection and compare these metrics with manual severity gradings. Methods: Slit lamp images from 139 glaucoma patients were included. Images from 103 participants were used as the primary development dataset and the remaining as a validation subset. The images were independently graded by two graders for conjunctival hyperemia using the Efron Grading Scheme. Conjunctival vessels were detected using an automated vessel detection pipeline based on semi-supervised learning. Vessel density, fractal dimension and tortuosity were calculated and compared with the manual Efron grades. Results: Grading of conjunctival hyperemia between the two graders were consistent (Spearman's rho: 0.79; ICC: 0.79 [95%CI: 0.72-0.84]) but showed significant differences with a higher proportion of differences in the moderate grades. Of the vascular metrics, vessel density showed significant associations with the individual Efron grading and against the mean Efron grading (0.78, p < 0.001). Fractal dimension was significantly associated with the mean Efron grading (0.55, p < 0.001). Agreements were similar in the subset (vessel density, 0.80, p < 0.001; fractal dimension 0.62, p < 0.001). Vessel tortuosity showed lower agreements (<0.23). Conclusions: Vessel density and fractal dimension showed significant associations with manual Efron gradings. These metrics could be potentially used to enable more objective and interpretable measures of conjunctival hyperemia severity.\n\nID: 42448871\nTitle: Ciliary sulcus tube placement may not protect the corneal endothelium in exfoliation glaucoma after Baerveldt glaucoma implantation.\nAbstract: \n\nID: 42448869\nTitle: Long-term outcomes of the Paul glaucoma implant in a paediatric population: A retrospective cohort study.\nAbstract: To evaluate the long-term efficacy and safety of the Paul Glaucoma Implant (PGI) in a paediatric cohort. A retrospective review of 113 eyes from 83 paediatric patients (age range 4 months to 18 years, mean 9\u2009\u00b1\u20095 years) who underwent PGI implantation between June 2019 and April 2024. Intraocular pressure(IOP), medications, complications, and surgical success rates were assessed. The mean preoperative IOP was 27.2\u2009\u00b1\u20096.2\u2009mmHg. Postoperatively, IOP significantly decreased at all time points (p\u2009<\u20090.001), measuring 14.0 at 12 months, 13.7 at 24 months, 12.5 at 36 months, 12.5 at 48 months, and 13.7 at 60 months. The mean number of preoperative medications was 3.8\u2009\u00b1\u20090.8. Postoperatively, they were 0.9 at 12, 18, and 24 months, 0.7 at 36 months, 1.0 at 48 months, and 0.7 at 60 months (p\u2009<\u20090.001). 59% of eyes were medication-free at final follow-up. Thirty-nine eyes (35%) underwent Prolene stent removal (mean 9.7 months post-op), resulting in further IOP reduction (14.3\u2009mmHg) and medication (0.8). Complete success rates (IOP\u2009\u2264\u200921\u2009mmHg without medication) were 67.2% at 1 year, 58.2% at 2 years, 51.9% at 3 years, 50.1% at 4 years, and 49.3% at 5 years. Qualified success rates (IOP\u2009\u2264\u200921\u2009mmHg with or without medication) were 91.2%, 88.5%, 85.8%, 85.0%, and 81.4% at the same intervals. 31(27.4%) eyes required further surgical intervention, most commonly for IOP control(21.2%). Major complications included tube exposure(2.7%) and hypotony(2.7%). PGI demonstrates sustained IOP reduction, reduced medication burden, and an acceptable safety profile in refractory paediatric glaucoma. It represents an effective long-term surgical option for this challenging cohort.\n\nID: 42448284\nTitle: Two-staged vs. single-staged Baerveldt implantation in children with glaucoma.\nAbstract: To compare two-staged vs. single staged Baerveldt implantation in children with glaucoma DESIGN: Retrospective observational case series SUBJECTS: Children (less than 18 years of age) who underwent Baerveldt glaucoma drainage device (GDD) placement with at 6 months of post-operative follow-up METHODS: Review of patients with at least 6 months of follow-up who underwent two-stage Baerveldt placement (n=25) between 2010 and 2025 and diagnosis and age-matched controls who had one-stage Baerveldt placement (n=40). Demographics, ocular diagnoses and surgeries, and exam findings (best corrected visual acuity (BCVA), intraocular pressure IOP), and glaucoma medications) were collected. Success and survival of Baerveldt GDD (IOP 5-21 mmHg, no additional IOP-lowering surgeries, and no visually devastating complications), BCVA, IOP and glaucoma medications. Children in the two-stage Baerveldt and single-stage Baerveldt (control) groups showed no difference in age at surgery, type of glaucomas, prior glaucoma and intraocular surgeries, or length of follow-up. There was also no significant difference in BCVA, IOP, or number of glaucoma medications between the two groups preoperatively or at final follow-up. However, there were fewer patients whose vision worsened between preoperative and final exams in the staged group (p=0.0011). In both groups, final IOP (p<0.0001) and number of glaucoma medications (p<0.05) were significantly decreased compared to preoperative exam. Success at final follow-up was 64% in the 2-stage group and 60% in the controls and there was no difference in survival curves (p=0.6629). Greater number of prior glaucoma surgeries was associated with increased risk of failure (OR 1.7, 95% CI [1.4, 2.2]). Two-staged Baerveldt placement in children obtained IOP control on fewer medications and showed similar success and survival rates to children who underwent single-staged Baerveldt surgery.\n\nID: 42448078\nTitle: Ophthalmic Disease Burden in Adults with Autism Spectrum Disorder.\nAbstract: To compare the documented prevalence of common treatable ocular conditions among US adults with and without autism spectrum disorder (ASD) in a large, socioeconomically diverse cohort. Propensity score-matched cohort study. Adults aged 18 years or older in the National Institutes of Health All of Us Research Program database, version 8, with electronic health record data. Adults with ASD were propensity score-matched 1:4 to adults without ASD on age, sex assigned at birth, race and ethnicity, and duration of electronic health record observation. Prevalence of each ocular condition was compared between groups, and absolute prevalence differences were estimated. Logistic regression was used to evaluate the association between ASD and ocular conditions; sequential models adjusted for household income, educational attainment, and health insurance status. Documented diagnoses of refractive/accommodative error, cataract, glaucoma, strabismus, dry eye disease, and any ocular condition. Among 5250 matched participants, 1050 adults had ASD and 4200 were controls; the cohort had a mean age of 39.1 years and was 49.3% male. Adults with ASD had higher documented prevalence of any ocular condition (29.5% vs. 17.8%), refractive/accommodative error (22.3% vs. 14.0%), cataract (9.9% vs. 5.2%), dry eye disease (9.0% vs. 5.5%), glaucoma (3.6% vs. 1.5%), and strabismus (3.8% vs. 1.7%) compared with controls. In fully adjusted models, ASD was associated with increased odds of any ocular condition (OR\u202f=\u202f2.09; 95% CI, 1.78-2.45), glaucoma (OR\u202f=\u202f2.56; 95% CI, 1.67-3.88), strabismus (OR\u202f=\u202f2.31; 95% CI, 1.53-3.44), cataract (OR\u202f=\u202f2.16; 95% CI, 1.68-2.77), refractive/accommodative error (OR\u202f=\u202f1.92; 95% CI, 1.61-2.29), and dry eye disease (OR\u202f=\u202f1.80; 95% CI, 1.39-2.32). Associations were similar from unadjusted through fully adjusted models. Adults with ASD had higher documented prevalence and odds of multiple treatable ocular conditions when compared to matched adults without ASD. Greater attention should be directed toward autism-informed adult eye care, including proactive screening, sensory and communication accommodations, and coordinated follow-up to support timely identification and management of ocular diseases in this population.\n\nID: 42447064\nTitle: Omidenepag isopropyl (Omlonti) for glaucoma.\nAbstract: \n\nID: 42446677\nTitle: One-year outcomes of the PAUL glaucoma implant versus ahmed glaucoma valve for the treatment of glaucoma following cataract surgery.\nAbstract: This study evaluated and compared the 1-year outcomes of the PAUL Glaucoma Implant (PGI) and the Ahmed Glaucoma Valve (AGV) in the management of aphakic glaucoma. A retrospective study was conducted on 30 eyes of 28 patients with aphakic glaucoma who underwent implantation of PGI (n\u2009=\u200910) or AGV (n\u2009=\u200920). Primary outcomes included surgical failure and success (complete or qualified). Secondary outcomes included intraocular pressure (IOP) reduction, best-corrected visual acuity (BCVA), medication use, and postoperative complications. Kaplan-Meier survival analysis was applied, with failure defined as IOP\u2009>\u200921 mmHg on two consecutive visits, implant removal, additional glaucoma surgery, or vision loss. At 12 months, surgical success was achieved in 90% of PGI eyes and 75% of AGV eyes (p\u2009=\u20090.766). Complete success occurred in 30% (PGI) and 25% (AGV), while failure occurred in one PGI eye and five AGV eyes. Kaplan-Meier analysis revealed comparable cumulative success rates (p\u2009=\u20090.475). Mean IOP at 12 months was similar between groups (16.0 vs. 16.4 mmHg; p\u2009=\u20090.854), with significant reductions from baseline (PGI: p\u2009=\u20090.002; AGV: p\u2009<\u20090.001). Both groups showed reduced medication burden (p\u2009<\u20090.001), with PGI requiring fewer agents at 1-2 months (p\u2009=\u20090.024). BCVA remained stable. One complication was recorded, a case of choroidal haemorrhage in the AGV group; the hypotony episode was not classified as a complication as it resolved without visual loss or further surgical intervention.). PGI and AGV both effectively managed aphakic glaucoma. PGI demonstrated a trend toward higher success rates and fewer complications; however, these differences were not statistically significant. These findings suggest that PGI may be a favourable alternative, although larger prospective studies are needed to confirm this potential advantage.\n\nID: 42446596\nTitle: Short and long-term exposure to fine particulate matter, nitrogen dioxide and meteorological factor and the risk of glaucoma: evidence from the China health and retirement longitudinal study, distributed lag non-linear and Mendelian randomization models.\nAbstract: This study investigates the relationship between environmental factors, meteorological data and air pollution (PM2.5, PM10, and NO2), and the risk of glaucoma, using a comprehensive approach combining time-series analysis, cohort data from the China Health and Retirement Longitudinal Study (CHARLS), and Mendelian randomization (MR). Using distributed lag non-linear models (DLNM), the study first analyzed air pollution and temperature data in Shenyang (2013-2021), revealing that ambient temperature did not show significant short-term effects on glaucoma incidence. In contrast, NO2 was significantly associated with short-term increases in glaucoma risk, particularly within a few days following exposure. PM2.5 demonstrated short-term effects, with a stronger risk observed during colder months, when pollutant levels were elevated. PM10 also exhibited a delayed impact on glaucoma risk, although its effect was less pronounced. Further analysis using CHARLS data confirmed these findings, with long-term exposure to PM2.5 and NO2 associated with higher odds and hazard of developing glaucoma, especially among smokers. To assess causality, Mendelian randomization analyses provided genetic evidence that genetically predicted exposure to PM2.5 (IVW OR\u2009=\u20091.367) and NO\u2082 (IVW OR\u2009=\u20091.463) were causally linked to an increased risk of glaucoma. The study found no significant causal association with PM10 or workplace (indoor) temperature exposure. Overall, this study underscores the critical role of air pollution, particularly PM2.5 and NO2, in glaucoma risk. It highlights the importance of environmental policies aimed at improving air quality, particularly for vulnerable populations such as smokers, and suggests further investigation into the underlying biological mechanisms of pollutant-induced glaucoma.\n\nID: 42446438\nTitle: Reply.\nAbstract: \n\nID: 42445927\nTitle: The Crescent Sign of Anterior Capsular Tear Detection Using Ultrasound Biomicroscopy.\nAbstract: This case report describes a novel imaging sign denoting anterior lenticular capsular tear using ultrasound biomicroscopy (UBM) in a case of trauma with obscured direct visualization. A 40-year-old intravenous drug user was presented to the emergency department after injuring his right eye with a used hypodermic needle 4 days previously. Slit-lamp examination revealed an intense anterior segment reaction with corneal edema, limiting the view to deeper structures. UBM allowed lens visualization, which demonstrated a crescent hyperechoic anterior subcapsular shadow, which was not present in the fellow eye. As the anterior segment inflammation and corneal edema cleared with topical steroid treatment and antibiotic treatment, the traumatic cataract, posterior synechiae, and lens particles in the anterior chamber became evident. A review of published literature demonstrated a similar sign of crescent hyperechoic anterior subcapsular shadow that has been documented in two previous cases with disrupted anterior capsules and lens-particle glaucoma. UBM can be used for assessing anterior lenticular integrity and may aid in diagnosing lenticular injuries where a direct view is impossible. Lens crescent sign is a UBM finding that suggests lenticular injuries.\n\nID: 42445785\nTitle: Metabolic vulnerability, genetic susceptibility, and incident age-related eye diseases: a prospective cohort study.\nAbstract: Metabolic dysregulation is increasingly recognized as a systemic process contributing to chronic disease development, yet prospective evidence linking integrated metabolic vulnerability to age-related eye diseases remains limited. We investigated whether a biomarker-based metabolic vulnerability index (MVX) was associated with incident age-related ocular diseases and whether joint consideration of MVX and genetic susceptibility may help characterize relative risk patterns. A prospective population-based cohort of 206,311 participants from the UK Biobank was analyzed. MVX was evaluated as the primary exposure. Incident age-related macular degeneration (AMD), cataract, diabetic retinopathy (DR), and glaucoma were ascertained as outcomes. Associations were examined using Cox proportional hazards models, with hazard ratios (HRs) and 95% confidence intervals (CIs) estimated per 1-standard deviation (SD) increase in MVX. As secondary exploratory analyses, polygenic risk score (PRS) analyses were performed to explore whether metabolic vulnerability and genetic susceptibility jointly characterized relative risk patterns. During follow-up, 4,144 participants developed AMD, 13,574 cataract, 1,483 DR, and 5,525 glaucoma. After multivariable adjustment for demographic, socioeconomic, clinical, and lifestyle factors, each 1-SD increase in MVX was associated with higher risks of incident AMD (HR = 1.07; 95% CI: 1.03-1.11), cataract (HR = 1.04; 95% CI: 1.02-1.06), and DR (HR = 1.11; 95% CI: 1.05-1.18), whereas no significant association was observed for glaucoma (HR = 1.00; 95% CI: 0.97-1.03). In joint analyses, individuals with both high genetic risk and elevated MVX exhibited the greatest risks of AMD (HR = 2.32; 95% CI: 2.01-2.67), cataract (HR = 1.62; 95% CI: 1.49-1.76), and DR (HR = 3.84; 95% CI: 2.91-5.06), compared with those with low genetic risk and low MVX. These findings suggest that MVX may be relevant to population-level patterns of risk for several age-related eye diseases. However, further studies are needed to determine whether MVX provides meaningful predictive value or clinical utility beyond conventional risk factors.\n\nID: 42445161\nTitle: Case Report: Combined cataract surgery and goniosynechialysis in elderly patients with iridoschisis-a report of two cases.\nAbstract: Iridoschisis, a rare condition involving separation between the anterior iris stroma and deeper layers, primarily occurs in patients between 60 and 70\u202fyears of age. The disorder often produces a distinctive \"shredded wheat\" appearance from iris fibers floating in the anterior chamber, and it commonly coexists with angle-closure glaucoma and cataracts. We present two cases where combined surgical management proved effective. The first case was an 81-year-old woman with bilateral iridoschisis complicated by cataract. Following laser peripheral iridotomy (LPI), gonioscopic examination indicated continued angle closure. Combined phacoemulsification and goniosynechialysis surgery achieved normalized IOP and visual improvement through 18-month follow-up. The second patient was an 82-year-old man with bilateral iridoschisis and narrow angles. The first eye underwent standard cataract surgery. When operating on the second eye, intraoperative gonioscopy identified peripheral anterior synechiae, leading us to add goniosynechialysis. Postoperatively, both eyes showed excellent visual outcomes and stable IOP. For iridoschisis patients, the dual procedure of phacoemulsification and goniosynechialysis addresses two problems simultaneously: the cataract and the anatomical cause of angle closure. The combination thus offers a practical solution for complex iridoschisis cases.\n\nID: 42445155\nTitle: Twenty-four-hour intraocular pressure profiles and gonioscopic findings after gonioscopy-assisted transluminal trabeculotomy in primary open-angle glaucoma: a retrospective case series.\nAbstract: To investigate changes in 24-h intraocular pressure (IOP) profiles and gonioscopic findings before and after gonioscopy-assisted transluminal trabeculotomy (GATT) in patients with primary open-angle glaucoma (POAG). This retrospective case series included 15 patients (25 eyes) with POAG who underwent GATT at the Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Chengdu University of Traditional Chinese Medicine, between January 2019 and January 2022 and completed pre- and postoperative 24-h IOP monitoring. Postoperative monitoring was performed at 3-6 months after surgery, after IOP-lowering medications had been discontinued for at least 7 days. Patients were followed for 2 years. Outcomes included pre- and postoperative 24-h IOP parameters, office IOP and medication burden at baseline and 2 years, and gonioscopic findings. The 24-h IOP peak decreased significantly from 26.16 \u00b1 1.44 mmHg preoperatively to 21.16 \u00b1 0.60 mmHg postoperatively (mean \u00b1 SD; P = 0.001). The trough IOP decreased from 17.52 \u00b1 0.66 mmHg to 16.25 \u00b1 0.42 mmHg (mean \u00b1 SD; P = 0.098). IOP fluctuation decreased significantly from 8.68 \u00b1 0.98 mmHg to 4.91 \u00b1 0.34 mmHg (mean \u00b1 SD; P < 0.001). Mean office IOP decreased from 21.58 \u00b1 1.03 mmHg at baseline to 18.45 \u00b1 0.51 mmHg at 2 years (mean \u00b1 SD; P = 0.005), while the median number of medications decreased from 3 (2, 4) to 0 (0, 1). Gonioscopy showed no significant change in Spaeth angle grading across quadrants. Peripheral anterior synechiae were significantly more frequent postoperatively in the nasal and temporal quadrants, while trabecular meshwork pigmentation grade changed significantly in the nasal, temporal, and superior quadrants. In this small retrospective case series of POAG eyes, GATT was associated with reductions in 24-h IOP peak and fluctuation, sustained office IOP lowering, and marked medication reduction. Gonioscopy showed stable overall angle configuration, more frequent postoperative PAS in the nasal and temporal quadrants, and postoperative changes in trabecular meshwork pigmentation grade in some quadrants. These findings should be interpreted cautiously and confirmed in larger prospective studies.\n\nID: 42443483\nTitle: Revisiting the sclera as a target for glaucoma therapy.\nAbstract: The pursuit of improved intraocular pressure (IOP) control in glaucoma continues to drive innovation beyond conventional trabecular-based therapies. While minimally invasive glaucoma surgery (MIGS) has focused attention on enhancing conventional outflow, increasing evidence suggests that the sclera represents a biologically active and potentially modifiable interface influencing unconventional aqueous drainage and transscleral drug delivery. Traditionally regarded as a passive structural barrier, the sclera is now recognized as a spatially heterogeneous, mechanosensitive tissue with region-specific extracellular matrix composition and biomechanical properties. Emerging data demonstrate that pharmacologic agents such as prostaglandin analogues can remodel scleral extracellular matrix architecture, increasing molecular permeability and facilitating uveoscleral outflow. At the same time, advances in transscleral drug delivery including iontophoresis, ultrasound-assisted diffusion, biodegradable matrices, and extracellular vesicle-based platforms highlight the sclera's dual role as both a hydraulic regulator and a therapeutic conduit. However, translational challenges including diffusion-dominated transport, episcleral clearance, fibrotic encapsulation, and dose variability have, to date, limited the widespread clinical adoption of transscleral strategies. In this review, we synthesize structural, biomechanical, pharmacologic, and translational evidence to propose a refined framework: the sclera as a dynamically remodeling hydraulic interface that may be selectively modulated to influence aqueous outflow and enable targeted posterior segment delivery. This integrative perspective expands the therapeutic paradigm for glaucoma beyond trabecular intervention alone.\n\nID: 42443340\nTitle: Cumulative loneliness and social isolation are associated with incident glaucoma in Chinese and US cohorts.\nAbstract: To investigate the association of cumulative loneliness and social isolation with glaucoma risk among middle-aged and older adults in Chinese and American populations, we conducted an observational cohort study using data from the China Health and Retirement Longitudinal Study (CHARLS; n\u2009=\u20097,098 for loneliness and n\u2009=\u20098,481 for social isolation) and the Health and Retirement Study (HRS; n\u2009=\u20096,982 for loneliness and n\u2009=\u20095,011 for social isolation). Cumulative exposure was defined as reporting loneliness or social isolation at two time points (0, 1, or 2 times). In CHARLS (median follow-up: loneliness 4.90 years, social isolation 4.89 years; incident glaucoma cases: loneliness 185, social isolation 221), one-time loneliness (HR 1.49; 95% CI 1.01-2.20) and two-time loneliness (HR 1.99; 95% CI 1.39-2.86) were associated with a higher risk of self-reported incident glaucoma. Similar associations were observed for one-time social isolation (HR 1.47; 95% CI 1.01-2.15) and two-time social isolation (HR 1.77; 95% CI 1.14-2.76). In HRS (median follow-up: loneliness 4.86 years, social isolation 5.09 years; incident glaucoma cases: loneliness 566, social isolation 347), only two-time cumulative exposure was significantly associated with a higher risk of self-reported incident glaucoma: loneliness (HR 1.38; 95% CI 1.05-1.83) and social isolation (HR 1.30; 95% CI 1.01-1.66). These observational findings suggest that cumulative loneliness and social isolation may be relevant psychosocial markers for future eye-health research and should be interpreted as associative and hypothesis-generating.\n\nID: 42443286\nTitle: Fractal Sierpinski triangle block division for retina-based glaucoma detection using an optimized hybrid deep learning model.\nAbstract: Glaucoma is a primary cause of permanent vision loss, and it often gets worse without anybody noticing. This makes it very important to find it early to stop vision loss. Manually evaluating retinal fundus images frequently necessitates considerable effort and is prone to observer-dependent discrepancies. To address these constraints, a new automated method for detecting glaucoma is presented. It combines fractal-inspired Sierpinski triangle spatial decomposition with multi-scale triangular segmentation to reliably identify clinically important areas of the retina. Handcrafted descriptors that include statistical, frequency-domain, wavelet, morphological, and texture-uniformity data are taken from small areas, giving a detailed and unique picture of the structures in the retina. A hybrid deep learning system that combines bidirectional LSTM, bidirectional GRU, and CNN with Bi-LSTM models that have attention layers captures spatial-temporal connections while highlighting essential visual cues for diagnosis. The Harris Hawks Optimizer, Grey Wolf Optimizer, Red Fox Optimizer, and Social Feature Optimizer are all examples of meta-heuristic algorithms that improve the feature subset. The HHO-based version gives the best results. A thorough examination using benchmark datasets shows that the system works very well, with 98.48% accuracy on Drishti-GS, 98.99% on Origa, 97.44% on RimOne-V2, 97.80% on HVD Binary-Class, 99.02% on HVD-Advance, 98.05% on HVD-Early, and 97.11% on HVD Multi-Class trials. The proposed system shows high reliability and stability in glaucoma diagnosis, delivering consistent performance across multiple datasets. It provides a scalable, non-invasive, and efficient solution for automatic detection, supporting doctors in early treatment and improving patients chances of recovery.\n\nID: 42442493\nTitle: A covalent inhibitor targeting Cys-349 of LIMK1 confers selectivity over LIMK2.\nAbstract: LIM domain kinase 1 (LIMK1) has been identified as a promising therapeutic target for a variety of conditions, such as chronic pain, open-angle glaucoma, various cancers, schizophrenia, and Fragile X syndrome. However, identifying inhibitors that selectively inhibit LIMK1 over LIM domain kinase 2 (LIMK2) has proven to be challenging. A viable strategy to overcome this difficulty is the development of covalent inhibitors, which can offer both potency and selectivity for LIMK1 due to a reactive cysteine, C349, near the active site absent in its paralog LIMK2. Here we identify an irreversible covalent inhibitor of LIMK1 (cLIMK1i), which is highly selective for LIMK1 over both LIMK2 and a panel of over 100 kinases. A crystal structure of LIMK1 soaked with cLIMK1i reveals it is a type I inhibitor occupying the ATP-binding site with its acrylamide moiety oriented toward the P-loop where C349 resides. Computational modeling supports that the P-loop of LIMK1 can adopt a conformation compatible with covalent bond formation. Biochemical and biophysical characterization of the interaction of cLIMK1i with LIMK1 demonstrates that the covalent bond with LIMK1-C349 is essential for its potent inhibition. These results support covalent inhibition of LIMK1 as a viable strategy for selectively inhibiting LIMK1 over LIMK2 and other kinases.\n\nID: 42461929\nTitle: Long-Acting RXR Agonism Preserves Retinal Function and Modulates Inflammation in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss and is associated with reduced nuclear retinoid X receptor (RXR) activity. Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy.\n\nID: 42460327\nTitle: Neurovascular unit uncoupling in diabetic retinopathy: molecular mechanisms and stage-adapted therapeutic strategies.\nAbstract: Diabetic retinopathy (DR) is a major neurovascular complication of diabetes and remains a leading cause of vision loss among working-age adults worldwide. Although DR has traditionally been classified as a microvascular complication, it is now increasingly recognized as a neurovascular degenerative disorder involving coordinated injury to neuronal, glial, vascular, and extracellular matrix components of the retinal neurovascular unit (NVU). The NVU provides the structural and functional basis for coupling neuronal activity to local blood flow and for maintaining retinal immune and barrier homeostasis. In diabetes, chronic hyperglycemia, oxidative stress, inflammation, metabolic dysregulation, impaired vascular endothelial growth factor (VEGF)/angiopoietin-Tie (Ang/Tie) signaling, abnormal intercellular communication, and epigenetic memory progressively disrupt the coordinated interactions among NVU components, leading to neurovascular uncoupling. This concept helps explain why retinal functional abnormalities and neurodegenerative changes may precede clinically visible vascular lesions. In this review, we summarize cell-specific NVU alterations and the molecular mechanisms that drive neurovascular uncoupling in DR. We also discuss how this framework may support earlier diagnosis, mechanism-based phenotyping, and stage-adapted treatment strategies. Established therapies, including anti-vascular endothelial growth factor (anti-VEGF) agents, corticosteroids, and angiopoietin-2 (Ang-2)/Tie-2-directed vascular stabilization, are considered together with investigational approaches targeting oxidative stress, inflammation, neuroprotection, metabolic reprogramming, epigenetic regulation, and drug delivery. Reframing DR as a diabetes-driven disorder of early NVU uncoupling may help shift clinical thinking from late vascular rescue toward mechanism-based neurovascular protection, precision phenotyping, and stage-adapted intervention.\n\nID: 42459363\nTitle: Inhibiting the uPAR/FPR1 interactions reduces blood-retinal barrier breakdown and improves retinal function in a rat model of diabetes.\nAbstract: Diabetic retinopathy (DR) is a leading cause of blindness characterized by early neurovascular damage driven by hyperglycemia-induced mechanisms, including inflammation. The system composed of the urokinase-type plasminogen activator (uPA) and its receptor (uPAR) has previously emerged as a potential regulator of the pro-inflammatory events in DR, possibly through the interaction of uPAR with its lateral partners, such as formyl peptide receptors (FPRs). This study explored whether the inhibition of uPAR/FPR1 crosstalk may reduce early neurovascular alterations in DR by targeting inflammation. To this aim, the new FPR1 antagonist N-19004 was tested in a rat model of streptozotocin-induced diabetes. N-19004 was administered subcutaneously for 7\u202fdays at 1\u202fmonth from diabetes onset. Immunofluorescence, RT-qPCR, Western blot and Evans blue perfusion were performed to evaluate the effects of N-19004 on inflammation, reactive gliosis, blood-retinal barrier (BRB) integrity and apoptosis. In addition, electroretinogram (ERG) was used to assess N-19004 efficacy on retinal function. N-19004 inhibited the activation of inflammation-related transcription factors, including nuclear factor kappa-light-chain-enhancer of activated B cells and signal transducer and activator of transcription 3, leading to reduced interleukin-1\u03b2 and tumor necrosis factor-\u03b1 expression. The attenuation of inflammatory processes resulted in reduced glial activation, as indicated by lower glial fibrillary acidic protein expression and M\u00fcller cell gliosis. The anti-inflammatory activity of N-19004 was accompanied by decreased BRB breakdown, as demonstrated by N-19004-mediated reduction of vascular endothelial growth factor, increased levels of tight junction components and diminished vessel leakage. The amelioration of BRB integrity was associated with reduced activation of caspase 3 and partial preservation of scotopic ERG a- and b-wave amplitudes, thereby improving retinal viability and function in N-19004-treated STZ rats. These results support the possible involvement of uPAR/FPR1 interactions in the regulation of DR-related inflammation and suggest a novel therapeutic target for the management of the early phases of disease.\n\nID: 42442776\nTitle: The Diverse Role of ipRGCs in Visual Perception Beyond Non-Image-Forming Functions.\nAbstract: The intrinsically photosensitive retinal ganglion cells (ipRGCs) are the third class of photoreceptors apart from rods and cones, containing the photopigment melanopsin and are characterized into different subtypes (M1-M6) that support conscious visual perception. They transmit the light information to the brain through complex circuits serving both non-image-forming and image-forming functions. Of the total population, there are four main ipRGCs, such as M2, M4, M5 and M6 that project substantially to the image-forming visual pathway and target the dorsal lateral geniculate nucleus (dLGN). Recent research has shown that they can modulate the excitatory and inhibitory balance in the primary visual cortex (V1) and thereby boost cortical computations for orientation discrimination. However, the projections of these ipRGCs to the V1 and how they integrate melanopsin signals with the conventional retinal ganglion cells is not yet clear. In this review, we summarize the morphological, physiological and behavioural characteristics of the ipRGC population that project to dLGN and contribute to image processing. Further research to understand how they can potentially enhance sensory representations in the visual cortex would offer therapeutic advantage in several eye diseases causing blindness.\n\nID: 42436854\nTitle: AAV-norrin gene therapy rescues retinal defects in mice with Norrie disease and oxygen-induced retinopathy.\nAbstract: Norrin, secreted by retinal M\u00fcller cells, activates canonical Wnt signaling via Frizzled-4 and co-receptors. Loss-of-function mutations abolish intraretinal capillary formation in mice. In humans, mutations in NDP, which encodes norrin, cause Norrie disease, characterized by retinal hypovascularization and congenital blindness, and X-linked familial exudative vitreoretinopathy (FEVR), resembling retinopathy of prematurity (ROP). We evaluated adeno-associated viral (AAV) vectors expressing norrin as gene therapy for Norrie disease, FEVR, and ROP. AAV2-7m8 and AAV-ShH10 were tested in juvenile wild-type and norrin-deficient (Ndp KO) mice via intravitreal injection at postnatal day 7, with some mice subjected to oxygen-induced retinopathy (OIR). AAV2-7m8 transduced M\u00fcller glia, while AAV-ShH10 targeted retinal ganglion cells. Both vectors fully restored intraretinal capillary growth in Ndp KO mice, normalizing vessel density and plexus organization, preserving the blood-retinal barrier, and rescuing visual function. In OIR, scAAV2-7m8-huNorrin reduced vaso-obliteration and neovascular tuft formation, increasing deep plexus coverage, and suppressed Vegfa164 and Ang-2 upregulation. The findings demonstrate that AAV-mediated norrin delivery efficiently targets retinal glia and neurons, restores vascular structure and function, stabilizes the blood-retinal barrier, and mitigates OIR-induced pathological angiogenesis, supporting its potential as a therapeutic strategy for Norrie-related retinopathies and ROP.\n\nID: 42435831\nTitle: Evaluation of the impact of gamma-aminobutyric acid on diabetic retinopathy in a large US population-based cohort.\nAbstract: To investigate how exposure to GABAergic medications affects diabetic retinopathy (DR) development, progression, and complications. Retrospective clinical cohort study using multi-institutional electronic health record data (TriNetX, US Collaborative Network) PARTICIPANTS: : Adults aged \u226518 years with type 2 diabetes mellitus with ophthalmology follow-up. Study cohorts had GABAergic prescription records for 6-months, 1-year, 3-years, or 5-years; control cohorts had no GABAergic prescriptions ever. Cohorts were propensity-score matched (PSM) on demographics, systemic comorbidities, common indications for GABAergic medications, and ophthalmic confounders. Outcomes included incident DR, progression from mild/moderate nonproliferative DR to severe nonproliferative DR, proliferative DR, or interventions required in advanced DR, and incident DR complications. Hazard ratio (HR) and 95% confidence intervals (CI); significance threshold <0.9 or >1.1. After successful PSM, there were 110,495 (6-months), 99,187 (1-year), 63,194 (3-years), and 40,810 (5-years) DR-naive study patients with the respective GABAergic prescription durations of interest. Compared to 109,603 DR-naive control patients, study patients demonstrated a significantly reduced HR for DR development at all time points from 6-months (HR 0.61, 95% CI 0.57-0.65) to 5-years (HR 0.81, 95% CI 0.77-0.85). Study patients (n=14,644) with baseline mild/moderate nonproliferative DR had a significantly reduced hazard of progressing to severe nonproliferative DR, proliferative DR, or DR interventions with 6-months (HR 0.75, 95% CI 0.68-0.82) and 1-year (HR 0.69, 95% CI 0.73, 0.86) GABAergic exposure. Prescription for 6-months (HR 0.74, 95% CI 0.68-0.80) to 3-years (HR 0.80, 95% CI 0.84-0.86) was associated with a significantly reduced hazard for DR complications. Stratification by 4 specific medication indications consistently showed a reduced hazard for DR development with a 6-month prescription duration. GABAergic medication use, particularly short-term exposure, is associated with a reduced hazard of DR development, progression, and complications. These exploratory findings support a potential role of GABAergic modulation in diabetic retinal disease.\n\nID: 42427758\nTitle: Exosomal Profiling Reveals Mechanisms of Hibernation-Associated Neuroprotection.\nAbstract: Glaucoma is a group of eye diseases that affects 4 million people in the US and is one of the leading causes of vision loss due to damage to the eye's optic nerve (ON) which is composed of axons from retinal ganglion cells (RGCs) that transmit visual information to the brain. Injury to the ON often triggers RGC death and subsequent loss of visual function. Despite its increasing prevalence worldwide, effective therapies for glaucoma remain elusive. Notably, the thirteen-lined ground squirrel (TLGS) exhibits intrinsic neuroprotection during hibernation; however, reproducing this protective state pharmacologically has proven challenging. To elucidate the metabolic mechanisms underlying this resilience, we conducted untargeted metabolomic analyses on TLGS retinas at 6 hours, 3 days, and 7 days following ON crush. Retinas from awake and hibernating animals were compared to identify temporal and state-dependent metabolic signatures. Distinct metabolomic profiles were observed in hibernating animals relative to their awake counterparts. Pathway analyses revealed coordinated regulation of amino acid, lipid, and purine metabolism that likely contributes to hibernation-induced resilience. Furthermore, our findings indicate that hibernating TLGS retinas increase exosome biogenesis, prompting in vitro validation using TLGS-derived exosomes, which demonstrated robust neuroprotective and anti-inflammatory effects. Proteomic and transcriptomic characterization of exosomal cargo identified conserved miRNAs, mRNAs, and proteins implicated in redox balance, cytoskeletal stabilization, and stress-response regulation. Collectively, these data support the hypothesis that metabolic reprogramming and exosome-mediated intercellular signaling underlie hibernation-associated neuroprotection. Modulating these pathways may provide a blueprint for novel therapeutic strategies to mitigate neurodegeneration and promote recovery following optic nerve injury.\n\nID: 42377658\nTitle: Ginkgo biloba extract as a retinal protective agent: a systematic review of preclinical experiments.\nAbstract: Ginkgo biloba extract (EGb), a complementary and alternative medicinal option, has gained extensive application in addressing conditions like cerebrovascular and peripheral vascular disorders. We aim to assess the neuroprotective efficacy of EGb for retinal disorders and to clarify its potential mechanisms of action through a systematic review. We searched original literature about laboratory experiments from four databases which were released until April 2024. The methodological quality of included in vivo studies was assessed using the SYRCLE risk of bias tool. The results showed that out of the 398 studies initially collected, 26 articles met the requirements for full-text review. 20 of them presented in vivo data, 2 detailed both in vitro and in vivo evidence, and 4 were in vitro experiments. Results demonstrated the protective effects of EGb against several retinal disorders, including retinal ganglion cell injury, retinal degeneration, ischemia, vitreo- or pre-retinal proliferative disorder, uveitis, and diabetic retinopathy. Based on SYRCLE's evaluation of bias risk, the in vivo studies' quality scores varied from 4 to 7 points. The data indicated that EGb preserved visual function by maintaining retinal morphology and structure in preclinical models. Its action mechanism may be associated with suppressing apoptosis, attenuating oxidative stress, reducing inflammation, inhibiting angiogenesis, and suppressing proteolysis. These preclinical findings suggest that EGb may be a promising neuroprotective agent for retinal disorders. However, the methodological limitations of the included studies necessitate cautious interpretation; to demonstrate the effectiveness and safety of EGb, more extensive clinical randomized controlled trials are required.\n\nID: 42365203\nTitle: Neuroinflammation in glaucoma: a myriad of cellular pathways and players.\nAbstract: Glaucoma is a complex neurodegenerative disease with multiple subtypes, yet all are characterized by the progressive dysfunction and loss of retinal ganglion cells (RGCs), which ultimately results in vision impairment and blindness. Elevated intraocular pressure (IOP) is a major risk factor for glaucoma; however, it is neither necessary nor sufficient for glaucomatous neurodegeneration, as patients can exhibit high IOP without developing glaucoma and patients can develop glaucoma with normal IOP. Yet FDA-approved treatment options are largely limited to approaches to minimize risk and reduce IOP. Thus, there is a critical need to target other aspects of glaucoma pathophysiology. Neuroinflammation is broadly defined here as immune-relevant responses, often involving microglia and astrocytes, within the central nervous system which may include peripheral immune cell infiltration. Burgeoning evidence has implicated glia in the development and progression of glaucoma in human tissues and mouse models. Most mouse models of glaucoma to date have shown that microglia and astrocytes are reactive in early stages of glaucomatous neurodegeneration prior to overt RGC loss. However, there is growing evidence that human and mouse glia adopt distinct phenotypes in response to neurodegeneration. Thus, there is critical need to expand our studies to include the new generations of human cell culture models. In this review, we discuss: 1) the evidence of neuroinflammatory processes in human glaucoma; 2) models of glaucoma relevant neuroinflammation; and the evidence specifically for 3) innate immune cell-driven and 4) macroglia-driven processes.\n\nID: 42364138\nTitle: Agreement between ganglion cell-inner plexiform layer metrics from widefield optical coherence tomography and Goldmann II, III, and V in glaucoma.\nAbstract: To compare concordance between ganglion cell-inner plexiform layer metrics acquired using widefield optical coherence tomography (OCT) and visual function assessed using Goldmann (G) II, III, and V stimulus sizes, in turn evaluating the role of spatial summation properties in binary classification of visual field (VF) results. Eighty three glaucoma and 34 healthy participants underwent widefield OCT scans, segmented to generate ganglion cell-inner plexiform layer measurements, and 24-2 VF assessment using GII, GIII, and GV in full threshold mode. Accuracy was assessed using mean weighted absolute error and 95% prediction interval width from mixed effects models between ganglion cells per stimulus area estimated from ganglion cell-inner plexiform layer thicknesses and VF thresholds compared using mixed effects models and post hoc analyses of estimated marginal means. Across healthy and glaucoma eyes, mean weighted absolute error and 95% prediction interval widths were smallest with GV (p\u00a0<\u00a00.0001), suggesting the least model variability with GV. With VF locations in glaucoma cohort subclassified into VF nondefective and VF defective, although significant differences in mean weighted absolute error and 95% prediction interval widths were noted within stimulus sizes (p\u00a0<\u00a00.0001), larger values indicating poorer model accuracy were noted in glaucoma VF defective locations relative to both healthy and VF nondefective models. Larger mean weighted absolute errors and 95% prediction interval widths were observed with increasing disease stage in VF defective locations across all stimulus sizes (p\u00a0<\u00a00.0001). Overall, structure-function models in healthy eyes and VF nondefective locations were similar across all stimulus sizes, but larger deviations were observed in VF defective locations and with worsening glaucoma stage. Our findings suggest that GIII sufficiently balances measurement variability and VF defect detection, but that disease stage-specific variations in the structure-function relationship exist and the ability to monitor VF defect progression over time is poor regardless of stimulus size.\n\nID: 42356426\nTitle: Neuroprotective Indole Diterpenoids from the Fungus Tolypocladium album DWS131.\nAbstract: Context/Objective: Fungi of the genus Tolypocladium are known for their diverse metabolic capabilities and medicinal potential. Indole diterpenoids (IDTs) represent a structurally unique class of fungal metabolites. Beyond their established roles as mycotoxins, these compounds have recently shown promise for neuroprotective effects. The objective of this study was to isolate and characterize novel IDTs from Tolypocladium album DWS131 and evaluate their neuroprotective activities and underlying mechanisms. Methods: IDTs were isolated through comprehensive chromatographic techniques. Their structures were elucidated using HRESIMS data, 1D/2D NMR spectra, and quantum chemical calculations. Neuroprotective effects were evaluated using glutamate (Glu)-induced R28 cells in vitro and N-methyl-D-aspartic acid-induced mouse models in vivo. A total of 48 mice were utilized for in vivo evaluations, divided into two separate experimental cohorts. In each cohort, mice were randomly assigned to four groups (n = 6 per group). Post-intravitreal injection, retinal survival and visual function were assessed via Brn3a-stained flat-mounts, H&E staining, f-VEP, f-ERG, and OptoDrum. Mechanisms involving the SLC7A11/GPX4/ACSL4 axis were investigated by Western blotting and immunofluorescence. Results: Seven previously undescribed paxilline-type IDTs, tolypindoles A-G (1-7), and two known analogues (8-9) were identified. Compounds 8 and 9 exhibited significant neuroprotection closely associated with the attenuation of oxidative stress and the modulation of ferroptosis-related pathways in Glu-induced R28 cells. In vivo, they preserved retinal ganglion cells, maintained retinal structure, and protected visual function, with compound 8 demonstrating superior efficacy. Mechanistic investigations revealed that both compounds modulate the SLC7A11/GPX4/ACSL4 signaling axis. Conclusions: This study expands the chemical diversity of T. album DWS131. Compounds 8 and 9, characterized by isopentenyl moieties, highlight a promising therapeutic potential for retinal neurodegenerative diseases such as glaucoma.\n\nID: 42353267\nTitle: Neuroprotection in Early Diabetic Retinal Disease Using Eyedrop Delivery.\nAbstract: Diabetic retinal disease (DRD) has classically been defined as a microvascular complication of diabetes; however, the recent evidence highlighted the key role of neuronal degeneration during the earliest stages of its pathogenesis. Therefore, neuroprotection has emerged as a promising therapeutic strategy to prevent disease progression. Topical administration via eyedrops represents a non-invasive approach to deliver neuroprotective agents directly to the retina. This review summarizes the current advances in the field of neuroprotective therapies against early DRD with a special focus on topical delivery, including preclinical and clinical evidence, while discussing the relevance of the transscleral route of absorption in all of them. In this review, the most promising neuroprotective compounds under development will be discussed, highlighting the opportunity that they represent for treating early stages of DRD.\n\nID: 42352057\nTitle: Oxidative Stress in Glaucoma: From Pathogenic Mechanisms to Emerging Antioxidant Therapies.\nAbstract: Glaucoma is the leading cause of irreversible blindness worldwide and is characterized by progressive retinal ganglion cell (RGC) loss and optic nerve degeneration. While elevated intraocular pressure (IOP) remains the primary modifiable risk factor, a certain proportion of patients continue to deteriorate despite adequate IOP control, pointing to IOP-independent mechanisms of neurodegeneration. Oxidative stress-defined as an imbalance between the production of reactive oxygen species and the capacity of endogenous antioxidant defenses-has emerged as a central, multi-tiered contributor to glaucoma pathogenesis. In the anterior segment, chronic oxidative damage to the trabecular meshwork impairs aqueous humor outflow and drives IOP elevation. In addition, oxidative stress may impair ocular biomechanical integrity, including corneal hysteresis and lamina cribrosa, resulting in heightened susceptibility to IOP fluctuations. In the posterior segment, oxidative stress directly contributes to mitochondrial damage and vascular endothelial injury, leading to RGC apoptosis. The nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein 1 (Keap1) pathway coordinates the principal endogenous antioxidant response, while nicotinamide adenine dinucleotide (NAD+) depletion links redox imbalance to metabolic vulnerability of RGCs. This narrative review synthesizes evidence published up to March 2026 on the molecular mechanisms of oxidative stress in glaucoma, the role of biomarkers in aqueous humor and systemic circulation, and the translational landscape of antioxidant-based neuroprotection-including nicotinamide, coenzyme Q10, alpha-lipoic acid, and Nrf2-activating compounds. We highlight gaps between preclinical promise and clinical evidence, and outline priorities for future randomized controlled trials.\n\nID: 42351640\nTitle: Glaucoma and Autoimmunity: Immunopathogenic Mechanisms and Emerging Immunomodulatory Therapies.\nAbstract: Glaucoma is a chronic progressive optic neuropathy and one of the leading causes of irreversible blindness worldwide. Although elevated intraocular pressure remains the most important modifiable risk factor, increasing evidence suggests that immune dysregulation and autoimmune responses also contribute substantially to disease onset and progression. Clinical studies across different glaucoma subtypes have identified subtype-dependent immune abnormalities, including altered serum autoantibody profiles, dysregulated cytokine and chemokine expression, and changes in peripheral immune cell subsets. Experimental and translational studies further indicate that multiple immunopathogenic mechanisms are involved in glaucomatous neurodegeneration, including glial cell-mediated immune responses, activation of pattern recognition receptor signalling pathways, adaptive immune responses, and complement cascade dysregulation. These processes may interact to sustain chronic neuroinflammation, promote retinal ganglion cell injury, and accelerate optic nerve degeneration. Importantly, a better understanding of immune involvement in glaucoma has generated growing interest in immunomodulatory therapy as a potential strategy beyond intraocular pressure lowering. Targeting microglial activation, inflammatory signalling pathways, adaptive immune imbalance, and complement-mediated injury has shown neuroprotective potential in animal or in vitro models, whereas clinical evidence in glaucoma patients remains limited. These findings may provide preliminary directions for future therapeutic development. In this review, we summarise the current clinical evidence linking glaucoma with autoimmunity, discuss the major immune mechanisms implicated in disease pathogenesis, and highlight recent advances in immunomodulatory therapeutic strategies. Elucidating the immune basis of glaucoma may help pave the way for more precise and effective treatments for this complex optic neuropathy. We believe that immune dysregulation in glaucoma functions as a context-dependent amplifier of retinal ganglion cell injury rather than a uniform primary driver, with innate (microglia/astrocytes), adaptive (T/B cells, HSP-specific immunity), and complement pathways interacting to sustain neuroinflammation and neurodegeneration. This integrated immune response contributes to subtype- and stage-specific vulnerability, and targeting these maladaptive immune mechanisms represents a promising, precision-guided strategy for neuroprotection beyond intraocular pressure lowering.\n\nID: 42329877\nTitle: Disentangling crossing fibers with advanced dMRI methods reveals bundle-specific degeneration across the visual system in asymmetric glaucoma.\nAbstract: Diffusion magnetic resonance imaging (dMRI) is a non-invasive neuroimaging technique that enables in vivo assessment of white matter microstructure and is highly sensitive to tissue alterations associated with disease. Although substantial evidence links diffusion-derived metrics to underlying white matter tissue properties, the presence of complex within-voxel axonal configurations complicates their biological interpretation. Several methods have been proposed to assess diffusion properties of individual crossing axonal populations, but their validation and clinical applicability remain limited. Glaucoma, the second leading cause of blindness worldwide, is characterized by progressive loss of retinal ganglion cells and axonal damage in the optic nerve, leading to degeneration along the entire visual pathway. This degeneration includes secondary effects on fiber crossings within the optic chiasm, which are challenging to characterize with conventional diffusion methods. Here, we evaluated whether advanced diffusion metrics can detect microstructural alterations in these complex white matter configurations and whether these measures correlate with clinical markers of glaucoma severity. In this study, we evaluated 31 patients with asymmetric glaucoma and 31 healthy controls using advanced diffusion magnetic resonance imaging methods, including Diffusion Tensor Imaging, Constrained Spherical Deconvolution, multi-tensor fit via Multi-Resolution Discrete Search method, and Fixel-Based Analysis. We found significant differences of diffusion metrics in white matter tracts of the visual system, including the optic nerve, optic chiasm, optic tracts, and optic radiations. Moreover, diffusion metrics correlated with clinical ophthalmological parameters such as cup-to-disc ratio, visual field mean deviation, and retinal nerve fiber layer thickness. These findings support the use of advanced diffusion magnetic resonance imaging models as sensitive tools for detecting Wallerian degeneration and resolving complex white matter architecture in the human visual pathway, and demonstrate their utility to study other fiber-crossing regions throughout the brain.\n\nID: 42317267\nTitle: Vascular regeneration and blood flow recovery in glaucoma.\nAbstract: The retina and optic nerve rely on a tightly regulated neurovascular unit that sustains the highly dynamic and metabolically demanding neural tissues required for vision. Adequate oxygen and nutrient delivery are essential for maintaining tissue function and cellular survival. Over the past decades, extensive research within and beyond the field of ophthalmology has sought to elucidate the mechanisms that govern neurovascular regulation in health and disease. Growing evidence indicates that neurovascular dysfunction plays an important role in both the initiation and progression of glaucoma, a leading cause of irreversible blindness worldwide. Alterations in vascular architecture and blood flow may compromise the metabolic support required by retinal ganglion cells, increasing their vulnerability to injury and degeneration. While neurons possess limited regenerative capacity, the vascular system retains a remarkable degree of plasticity and is therefore amenable to repair. This vascular plasticity presents an opportunity to develop therapeutic strategies aimed at restoring vascular architecture and improving blood flow, complementing existing approaches focused on intraocular pressure reduction, neuroprotection, axonal regeneration, and/or neuronal transplantation. In this review, we summarize the current understanding of neurovascular function in the healthy eye, discuss mechanisms that contribute to vascular compromise in glaucoma, and highlight emerging avenues for promoting vascular regeneration and blood flow recovery. By identifying key knowledge gaps and future research priorities, we aim to outline promising directions for targeting the ocular neurovasculature to preserve retinal ganglion cell function and slow or stop progressive vision loss.\n\nID: 42292332\nTitle: Microglial regulation of synaptic plasticity in transsynaptic degeneration of glaucoma.\nAbstract: Glaucoma is a heterogeneous group of irreversible and blinding optic neuropathies caused by multiple factors. It is clinically characterized by progressive loss of visual field and decline in visual acuity, ultimately culminating in complete blindness. Hallmark pathological features include progressive degeneration of retinal ganglion cells and atrophy of the optic nerve. Importantly, the pathological process of glaucoma extends far beyond the eyeball, involving transsynaptic degeneration across the entire visual pathway. Microglia, as the principal immune regulators of the central nervous system, serve as the earliest sensors and effectors in the pathogenesis of glaucoma. By modulating synaptic plasticity, microglia contribute to synaptic loss and the disruption of neural circuits. They also play essential roles in maintaining neural tissue homeostasis. This review summarizes current evidence and underlying mechanisms of bidirectional transsynaptic degeneration in glaucoma. It highlights that targeting microglial functional homeostasis, particularly their regulation of synaptic plasticity, may be a promising strategy to mitigate glaucoma-associated transsynaptic degeneration and promote central neuroprotection.\n\nID: 42287272\nTitle: Visual Electrophysiology for the Diagnosis of Glaucoma: A Report by the American Academy of Ophthalmology.\nAbstract: To review the current published literature on the utility of visual electrophysiology testing in the diagnosis of glaucoma. Literature searches of the PubMed database were last conducted in August 2025 and restricted to articles published on or after January 1, 2011. The search identified 738 articles that were reviewed in abstract form for relevancy, and 170 were selected for full-text review. After inclusion and exclusion criteria were applied, 37 articles were selected for data abstraction by panel members. A total of 20 studies were selected for inclusion, and the panel methodologist (J.A.R.) assigned each a level of evidence rating. None of these 20 articles were rated level I, 1 article was rated level II, and 19 articles were rated level III. Visual electrophysiology tests, including electroretinography (ERG) and visual evoked potentials (VEP), are objective measures that provide an assessment of visual function. Pattern electroretinography (PERG) may assist the clinician's ability to diagnose early glaucoma before visual field deficits are detected, especially in patients with retinal nerve fiber layer (RNFL) loss as measured by OCT. The photopic negative response (PhNR) of the cone-driven full-field ERG is sensitive to glaucoma damage and has a less strict requirement for lack of media opacity and steady fixation compared with PERG. Visual evoked potentials and multifocal VEP (mfVEP) can discriminate between glaucoma and control eyes, but they are technically challenging to perform, which may limit their adoption for glaucoma diagnosis. Although significant advances have been made in developing these objective visual electrophysiology tests to discriminate between glaucoma and control eyes, they are not yet recommended in routine clinical evaluation. They may have a role in select scenarios to augment currently accepted structural and functional assessments. Utility is limited because of barriers to widespread clinical implementation, including the lack of consensus on stimulation and analysis protocols with standardized reference ranges. Proprietary or commercial disclosure may be found after the references.\n\nID: 42281784\nTitle: Intravitreal delivery of NGF-chitosan hydrogel confers retinal ganglion cell protection and visual function recovery in experimental glaucoma.\nAbstract: Glaucoma is one of the leading causes of irreversible blindness, and lowering intraocular pressure alone is insufficient to rescue lost retinal ganglion cells (RGCs) or restore visual function. In this study, we intravitreally injected a liquid chitosan gel loaded with nerve growth factor (NGF), previously developed by our group, into the vitreous body of rats with ocular hypertension-induced glaucoma. Using a combination of techniques--including multiplex immunofluorescence staining, TUNEL staining, CTB tracing, Western blotting, visual electrophysiology, and behavioral assessments--we demonstrated that, compared with the lesion control (LC) group, the NGF-chitosan hydrogel significantly enhanced RGC survival following glaucomatous injury (by approximately 27%), preserved dendritic architecture and long-distance axonal projections, and promoted recovery of visual function. Mechanistically, treatment with the NGF-chitosan hydrogel upregulated the expression of NGF and its high-affinity receptor, tropomyosin receptor kinase A (TrkA), in the retina. In addition, it suppressed retinal glial activation and enhanced mammalian target of rapamycin (mTOR) signaling, collectively contributing to RGC protection and repair. Notably, we further observed activation of Nestin+ neural stem cells in the ciliary body region, along with their differentiation into BrdU+/Brn3a+ neuron-like cells; the precise mechanisms underlying this phenomenon warrant further investigation. In conclusion, intravitreal delivery of NGF-chitosan hydrogel provides novel mechanistic insights and represents a promising therapeutic strategy for the treatment of glaucoma.\n\nID: 42247051\nTitle: Understanding Patient Preferences and Their Impact on Adherence to Glaucoma Therapy: A Multicenter Cross-Sectional Study.\nAbstract: Glaucoma is a progressive, irreversible optic neuropathy that leads to the loss of retinal ganglion cells, vision loss, and blindness. Elevated intraocular pressure (IOP) is the only modifiable risk factor, and topical hypotensive eye drops remain the mainstay of treatment, reducing disease progression by up to 60%. However, patient adherence to therapy remains a significant challenge since this disease is usually asymptomatic in its early stages. Patient preferences and individual characteristics play a key role in adherence. This study aimed to obtain further knowledge about patient preferences regarding glaucoma treatment to better understand factors influencing adherence. A cross-sectional, multicenter survey was conducted in Spain between March and December 2024 among patients with glaucoma receiving topical treatment for more than 6 months. A questionnaire was designed to collect patients' information about their beliefs, preferences, and adherence-related factors. Of 200 participants, 169 valid responses were analyzed. Most patients were aged 51-74\u00a0years, 60.2% were women, and 71.2% had been on treatment for more than 12\u00a0months. Although 93.5% recognized the importance of preservatives, only 36.0% reported having received information about them from their ophthalmologist. Preferences between multidose bottles (MDBs, 42.2%) and single-dose units (SDUs, 37.0%) were similar, although younger women (18-30\u00a0years) showed a preference for SDUs (p\u2009<\u20090.05). Perceived ease of handling was strongly influenced by prior experience. Most patients considered SDUs as more hygienic, whereas MDBs were perceived as more environmentally friendly; nearly 79% valued ecological impact. Self-reported adherence to therapy was moderate, with 57.6% of participants denying missed doses. Nonadherent patients were more likely to favor reminder systems (74.5%, p\u2009=\u20090.029). Treatment efficacy was ranked as the most important factor, followed by side effects, ease of use, cost, and environmental impact. This study highlights substantial variability in patient preferences and underscores the importance of personalized, patient-centered glaucoma care. Enhanced education on preservatives, improved communication, and sustainable packaging could improve adherence and satisfaction. Larger multicenter studies are needed to confirm these findings and inform long-term adherence strategies.\n\nID: 42224261\nTitle: Magnesium neuroprotection in retinal ganglion cells: A computational study of frequency-dependent therapeutic windows and intervention timing.\nAbstract: Retinal ganglion cells (RGCs) are vulnerable to excitotoxic damage mediated by excessive NMDA receptor activation and calcium overload. Extracellular magnesium (Mg2+) blocks NMDA receptors in a voltage-dependent manner, offering potential neuroprotection. However, the optimal Mg2+ concentrations and timing for effective intervention remain poorly defined. We developed a conductance-based computational model of an RGC incorporating Hodgkin-Huxley dynamics, AMPA and NMDA receptor-mediated synaptic transmission, and intracellular calcium dynamics. We systematically varied Mg2+ concentration (0.2-2.5 mM) and stimulation frequency (10-100 Hz) to identify therapeutic windows balancing neuroprotection with function preservation. At physiological frequencies (10-60 Hz), elevated Mg2+ reduced calcium (Ca2+) accumulation by 50-85% without affecting spike output. At excitotoxic frequencies (80 Hz), a narrow therapeutic window of 1.6-2.0 mM was identified, lying within a broader 1.4-2.0 mM spike-loss plateau (20% loss), where calcium additionally fell below the toxicity threshold while spike output was preserved. Intervention timing analysis revealed that Mg2+ protection efficacy is maximal with pre-treatment or immediate intervention (100%), and declines steeply with delay-reflecting the rapid early rise in Ca2+ rather than a fixed biological deadline (\u226550% protection requires intervention within 0.2 s in our abrupt-onset protocol; \u223c11% by 0.5 s). Re-analysis in terms of normalized Ca2+ progress revealed that the critical constraint for \u226550% protection is intervention before \u223c35% of peak Ca2+ accumulation-a state-based threshold reflecting relative phase sensitivity that generalizes across timescales. Sensitivity analyses confirmed robustness of the therapeutic window across physiologically plausible parameter ranges, and numerical validation demonstrated accuracy of the computational approach. These findings demonstrate that Mg2+-mediated neuroprotection is highly dependent on both concentration and timing, with implications for therapeutic strategies targeting glutamate excitotoxicity in glaucoma and retinal ischemia.\n\nID: 42217975\nTitle: Glaucoma.\nAbstract: Glaucoma, a prevalent cause of blindness, refers to a group of optic neuropathies that result in the degeneration of retinal ganglion cells. Glaucoma can be broadly classified based on the anatomy of the anterior chamber angle (open vs closed), though each group can be further subdivided by underlying etiology and chronicity. Given that chronic glaucoma is the most common type and usually progresses insidiously, periodic eye exams are critical to assess both anatomic integrity and visual function. The most important modalities for screening and monitoring at-risk patients or those with a diagnosis are ophthalmoscopy for appraising the appearance of the optic nerve head, gonioscopy for examining the anterior chamber angle, tonometry for measuring intraocular pressure, optical coherence tomography for evaluating structural damage to the optic nerve head, macula, and retinal nerve fiber layer, and perimetry for assessing visual function. Since most cases of glaucoma involve elevated intraocular pressure due to an abnormality in the drainage of aqueous humor out of the eye, current treatments, including medications, laser therapies, and surgeries, focus on lowering intraocular pressure. This chapter additionally includes a summary of significant clinical trials that have helped establish current standard practices, and concludes with an overview of promising emerging research, including stem cell therapies, gene therapies, visual prosthesis, and artificial intelligence/computer vision. Neurologists should be familiar with the diagnosis and management of glaucoma, given its similarities in pathophysiology with other neurodegenerative conditions as well as the fact that glaucoma affects both the eye and the brain.\n\nID: 42211201\nTitle: Differences of the lamina cribrosa between primary open angle glaucoma and non-pathologic high myopia.\nAbstract: Primary open angle glaucoma (POAG) is a chronic, blinding ocular disorder characterized by progressive degeneration of retinal ganglion cells (RGCs). Its incidence and prevalence of blindness continue to increase with global population aging. Non-pathologic high myopia (HM) has been established as an independent risk factor for POAG, and the two conditions share similar structural changes in the lamina cribrosa (LC) during the early phase of optic nerve injury. This review summarizes the common and distinct pathological alterations of LC in POAG and HM, with the aim of clarifying its central role in the initiation and progression of optic nerve damage. Elucidating these similarities and differences may facilitate early detection and targeted intervention strategies for at-risk individuals from a structural perspective.\n\nID: 42202976\nTitle: Multi-omics identification and verification of Dnajb14 as a modulator of retinal ganglion cell survival in glaucoma through ferroptosis.\nAbstract: Glaucoma is a leading cause of irreversible blindness and necessitates the identification of unreported therapeutic targets. Here, we report eight stable plasma protein targets for glaucoma, identified through a large-scale proteome-wide association study integrated with Mendelian randomization and colocalization analyses. Among these candidates, we show that the DnaJ heat shock protein family member B14 (DNAJB14) acts as a critical neuroprotective factor. Using single-cell and bulk transcriptomics, we demonstrate that Dnajb14 is characteristically expressed in retinal ganglion cells (RGCs) and that its abundance is inversely correlated with ferroptosis under ischemic stress. Furthermore, our results reveal that Dnajb14 preserve RGC survival and structural and functional integrity in multiple acute and chronic murine models. Mechanistically, Dnajb14 overexpression robustly alleviate ischemia-reperfusion-induced retinal injury, whereas targeted knockdown exacerbate lipid peroxidation, mitochondrial dysfunction, and ferroptosis. Taken together, our findings highlight that Dnajb14 is a key regulator of RGC survival through inhibition of ferroptosis, thereby making it a promising therapeutic candidate for glaucoma treatment.\n\nID: 42199109\nTitle: Beyond antioxidation: Retinal neuroprotection by Lycium barbarum polysaccharides via multiple signaling pathways.\nAbstract: Age-related macular degeneration, glaucoma, retinitis pigmentosa, and diabetic retinopathy are the major retinal degenerative disorders, and each ultimately leads to irreversible vision loss. In this context, single-target therapies aimed at isolated pathways have delivered only modest benefits. Lycium barbarum polysaccharides, the predominant bioactive components of goji berries, emerge as far more than simple antioxidants, functioning instead as orchestrators of interconnected signaling networks. Growing evidence shows that Lycium barbarum polysaccharides engages pathways well beyond redox control to interrupt disease-driving cascades: it limits cellular senescence through the SIRT1/p53 axis, preserves blood-retinal barrier integrity by maintaining aquaporin-4 at astrocytic endfeet, and biases microglia from proinflammatory M1 toward reparative M2 states. Beyond immunomodulation, Lycium barbarum polysaccharides promotes clearance of pathogenic protein aggregates and suppresses pathological neovascularization via the miR-15a-5p/ VEGFR2 axis. While antioxidant effects may predominate in early disease, the actions of LBP become more targeted as pathology advances, a stage-dependent selectivity that helps explain its cross-disease efficacy. In age-related macular degeneration, Lycium barbarum polysaccharides sustains metabolic homeostasis in retinal pigment epithelium by tuning autophagic flux through the miR-181/BCL-2 axis. In glaucoma, it safeguards mitochondrial membrane potential in retinal ganglion cells, supporting energy metabolism and survival. Collectively, these properties position Lycium barbarum polysaccharides as a pleiotropic regulator capable of reshaping multiple disease trajectories. Realizing its clinical potential will require precise identification of active metabolites, rigorous in vivo pharmacokinetic profiling, and rational combination with current standard-of-care therapies.\n\nID: 42196341\nTitle: Eyedrop Administration of DPP-4 Inhibitors: A New Strategy for Treating Early Stages of Diabetic Retinal Disease.\nAbstract: This review is intended to highlight the need for non-invasive and earlier therapies for diabetic retinal disease (DRD), one of the most common complications of diabetes, with a high and increasing socioeconomic burden. Due to the growing evidence regarding the key role of neurodegeneration in the earliest stages of the disease and the underlying pathophysiological mechanisms, the relevance of evaluating the potential efficacy of neuroprotective therapies is emphasized. More specifically, the review addresses the current state of a promising neuroprotective approach based on the inhibition of the enzyme dipeptidyl peptidase-4 (DPP-4) using specific inhibitors administered via eyedrops, which allow direct retinal action on the neurovascular unit. The review discusses the main preclinical findings of a therapeutic strategy based on one DPP-4 inhibitor, sitagliptin, against early DRD in different experimental animal models and in vitro studies. In summary, sitagliptin eyedrops exhibit neuroprotective, anti-inflammatory, and antioxidant properties while reducing glial activation, hyperpermeability of the blood-retinal barrier, and the formation of acellular capillaries, leading to a functional improvement of the diabetic retina. However, as sitagliptin efficacy has only been evaluated at the preclinical level, clinical studies are needed to validate the translational applicability and long-term efficacy of topical administration not only of sitagliptin but also of other DPP-4 inhibitors for treating retinal diseases in which neurodegeneration plays a pathogenic role.\n\nID: 42193462\nTitle: Advancements in Nanodrug Delivery Systems as Controlled-Release Systems for Glaucoma Therapy: An Inspirational Step Toward Translation from Research to Clinic.\nAbstract: Glaucoma is a collection of disorders that result in permanent vision loss and is characterized by a gradual decline in retinal ganglion cells. While it may not always be high, intraocular pressure (IOP) is the sole risk factor that can be modified according to extensive clinical research. Glaucoma remains the leading cause of irreversible blindness, yet early treatment lowering intraocular pressure is effective in slowing the rate of visual deterioration. Issues like poor absorption, low bioavailability, and short drug resistance time have thus made the management of glaucoma challenging when using conventional ophthalmic drugs. Thus, extensive research has been conducted to explore specific nanodrug delivery systems from various nanocarriers such as nanoparticles, micelles, liposomes and nanofibers, with a focus on systems that have achieved drug release for more than 12 h. These carriers have demonstrated substantial improvements in a lot of the evaluated aspects: enhancing ocular barrier-crossing capabilities, improving bioavailability, prolonging drug release, targeting active tissues of interest, and reducing IOP. This review covers recent developments in nanocarrier ocular delivery systems regarding the management of glaucoma. In this study, the advantages and disadvantages of each system were evaluated and their potential for advancing translation from research to clinic were assessed.\n\nID: 42179647\nTitle: Chronic exposure to aerosolized Arizona test dust reduces visual acuity in mice.\nAbstract: Air pollution is associated with increased incidence of age-related macular degeneration (AMD), glaucoma and other retinal diseases. The time course of molecular and cellular changes induced by chronic air pollution exposure that lead to retinal pathology are unknown. In this study, we investigated the effects of moderate levels of air pollution on visual acuity and retinal phenotypes in mice using Arizona test dust (ATD) as a surrogate for ambient air pollution. Mice were exposed to aerosolized standardized test dust for three hours a day, four days a week, for up to four months in a custom-built chamber. Controls were exposed to room air. Visual function was assessed using an optomotor assay and demonstrated reduced visual acuity after one month of exposure that persisted throughout the study. Rod and cone photoreceptors also showed temporarily decreased light-evoked responses that returned to normal levels by four months. Furthermore, reduced cone photoreceptors and retinal ganglion cells were observed whereas markers of retinal stress, including Iba1-positive microglia/macrophage and GFAP expression in macroglia, were not significantly elevated. Molecular analyses indicated elevated expression of genes in the Nrf2-ARE oxidative stress response pathway. Therefore, moderate levels of aerosolized ATD caused a persistent decline in visual acuity, mild retinal degeneration and transient functional changes. This study provides new information into the pathogenesis of pollution-induced retinal damage and establishes a new mouse model for investigating detrimental effects of moderate levels of air pollution in the retina.\n\nID: 42169105\nTitle: IL-1\u03b2-mediated interaction between M\u00fcller cells and microglia through CXCL1/5-CXCR2 aggravates visual dysfunction in experimental glaucoma.\nAbstract: Glaucoma is an optic neuropathy characterized by progressive death of retinal ganglion cells (RGCs), ultimately leading to blindness. Increasing evidence demonstrates that interactions among retinal glial cells exacerbate retinal inflammatory responses, which is closely associated with RGC injury. However, the detailed mechanisms governing these glial cell interactions remain largely unknown. This study aims to investigate the possible roles and the potential mechanisms of interleukin-1\u03b2 (IL-1\u03b2) in mediating the interaction between M\u00fcller cells and microglia in glaucoma. The experimental glaucoma model of chronic ocular hypertension (COH) was established in adult male mice by injection of micro-magnetic beads into the anterior chamber. Western blotting, quantitative real-time polymerase chain reaction, immunofluorescence, transwell co-culture of glial cells, RNA sequence, swept-source optical coherence tomography-based imaging and flash visually evoked potentials were employed to investigate the underlying mechanisms about the interaction of M\u00fcller cells and microglia in retina after IL-1\u03b2 stimulation, along with their impact on visual functions. We showed that in COH retinas, IL-1\u03b2 activated M\u00fcller cells and microglia, and promoted the recruitment of microglia to the ganglion cell layer. Mechanistic studies revealed that activated M\u00fcller cells released C-X-C motif chemokine ligand 1/5 (CXCL1/5) through the NF-\u03baB and p38 MAPK signaling pathways. These chemokines bond to CXC chemokine receptor 2 (CXCR2), inducing microglial activation and migration. This activation led to a significant increase in the expression of pro-inflammatory factors, which contributed to RGC death and subsequent visual function decline. Importantly, inhibition of the CXCL1/5-CXCR2 axis substantially reversed RGC loss and improved visual function. IL-1\u03b2 plays a positive feedback role in glial cell interactions, amplifying retinal inflammatory responses and impairing visual function. These findings demonstrate that inhibiting the interaction between M\u00fcller cells and microglia effectively protects RGCs, offering a promising strategic approach for glaucoma prevention and treatment.\n\nID: 42150720\nTitle: The orexinergic system in the retina: Expression and physiological impact-A review of the literature.\nAbstract: The neuropeptides orexin-A (OXA) and orexin-B (OXB), central orchestrators of arousal and energy homeostasis, are increasingly recognized as key neuromodulators within the vertebrate retina. This review synthesizes current evidence demonstrating a broad extra-hypothalamic expression of the orexin system across retinal neurons, including photoreceptors, bipolar (BCs), amacrine (ACs), and ganglion cells (GCs). We detail a sophisticated, cell-type-specific signaling framework where orexins exert complex, often antagonistic, presynaptic and postsynaptic actions via orexin 1 (OX1R) and orexin 2 (OX2R) receptors. These actions fine-tune signal transmission by potentiating glutamate release from BCs while suppressing GABAergic inhibition from ACs, ultimately modulating retinal output. A central theme emerging is the system's pivotal role in non-image-forming visual functions: OXA enhances the pupillary light reflex (PLR) by increasing the excitability of specific intrinsically photosensitive retinal ganglion cells (M2 ipRGCs), while OXB potentiates scotopic (dim-light) sensitivity by disinhibiting rod bipolar circuits. Furthermore, pharmacological inhibition of orexin receptors affects circadian rhythms in both the retina and hypothalamus. However, the field is marked by intriguing paradoxes, such as the stimulatory effects of receptor antagonists and significant species differences in OX2R expression. We critically evaluate evidence for a tonically active retinal orexin system that interfaces with dopaminergic signaling and circadian photic input. By integrating molecular, cellular, and behavioral findings, this review clarifies how retinal orexinergic modulation serves as a potential crucial interface between light detection, circadian physiology, and systemic arousal, while highlighting critical translational gaps and future research directions.\n\nID: 42143320\nTitle: Pharmacological restoration of impaired autophagy in retinal ganglion cells prevents abnormal mitochondrial accumulation and glaucomatous neurodegeneration.\nAbstract: Progressive loss of retinal ganglion cells (RGCs) and degeneration of optic nerve (ON) axons are the key pathological hallmarks of glaucoma, the leading cause of irreversible blindness. Elevated intraocular pressure (IOP), primarily due to dysfunction of the trabecular meshwork (TM), remains the most significant and only known modifiable risk factor. However, vision loss persists in some patients despite effective IOP control, highlighting the critical need to elucidate the mechanisms driving glaucomatous neurodegeneration. Emerging evidence links mitochondrial dysfunction to glaucomatous neurodegeneration, yet the precise mechanisms remain poorly defined. Here, we investigate whether defective autophagy/mitophagy, which removes damaged mitochondria, contributes to mitochondrial accumulation, oxidative stress, and neurodegeneration in glaucoma. We further explore the therapeutic potential of enhancing autophagy to improve mitochondrial turnover, mitigate RGC loss, and preserve visual function. Glucocorticoid (GC)-induced and myocilin (MYOC)-associated glaucoma mouse models were used to assess the expression of mitochondrial markers (TOM20/COX IV), oxidative DNA damage (8-OHdG), and mitophagy/autophagy-related proteins (p62, LC3, Phospho-ubiquitin (Ser65), and LAMP1) in retinal tissues. Transmission electron microscopy (TEM) was employed to analyze mitochondrial accumulation in glaucomatous ON. Mitophagy flux was assessed at early and late stages of neurodegeneration using mitophagy reporter Mt-Keima mice. The effect of RGC-specific autophagy deficiency on mitochondrial accumulation and neurodegeneration was further investigated using Atg5flox/flox mice, in which Atg5 deletion was induced by AAV2-Cre delivery. Additionally, the therapeutic effect of enhancing autophagy with Torin 2 to restore mitochondrial turnover and prevent glaucomatous neurodegeneration was evaluated in both GC-induced and myocilin-associated glaucoma models, as well as in ex vivo human retinal explants. Chronic IOP elevation led to increased mitochondrial accumulation, oxidative DNA damage, and impaired mitophagy/autophagy in glaucomatous retina. TEM analysis further confirmed the accumulation of structurally abnormal mitochondria in glaucomatous ON. In Mt-Keima mice, chronic IOP elevation significantly reduced mitophagy flux prior to RGC loss, indicating that mitophagy impairment precedes neurodegeneration. RGC-specific Atg5 deletion induced the accumulation of damaged mitochondria, leading to neurodegeneration in Atg5 flox/flox mice. Notably, pharmacological restoration of impaired autophagy with Torin 2 prevented mitochondrial accumulation and preserved the structural and functional integrity of RGCs and their axons in glaucoma mouse models and ex vivo human retinal explant cultures. Our study indicates impaired autophagy contributes to damaged mitochondrial accumulation and oxidative stress, leading to glaucomatous neurodegeneration. Enhancing autophagy in RGCs represents a promising therapeutic strategy to prevent glaucomatous neurodegeneration.\n\nID: 42141275\nTitle: Cytokine Gene Polymorphisms in Primary Glaucoma: Insights into Inflammatory Pathways and Future Directions.\nAbstract: Glaucoma is a leading cause of irreversible blindness worldwide. A substantial proportion of patients experience disease progression despite adequate IOP control, which is the most significant modifiable risk factor. This indicates the involvement of additional pathogenic mechanisms. One such mechanism is neuroinflammation within the retina and optic nerve head, spearheaded by resident glial cells. These activated glial cells initiate a cascade of proinflammatory cytokines that drives oxidative stress, excitotoxic injury, and ultimately apoptosis in retinal ganglion cells (RGCs), the cells that are responsible for vision. Given the central role of cytokines in mediating this neuroinflammatory damage, several genetic association studies have checked whether functional variants in the cytokine genes modify disease susceptibility to primary glaucoma. In this review, we critically compare and assess the strength of these associations in both open-angle and angle-closure glaucoma, highlighting the inconsistencies and population-specific variability, while also evaluating the limitations of current association studies and how to overcome these challenges. Second, we address a critical mechanistic gap-how cytokine gene variants may influence glial activation, and contribute to the inflammatory ocular microenvironment that may drive disease progression. Finally, we discuss if oxidative stress-driven epigenetic modifications may modulate cytokine gene expression and amplify inflammatory responses in individuals who might be genetically predisposed to develop primary glaucoma.\n\nID: 42140580\nTitle: A theoretical model for the influence of age, race and ethnicity on retinal mitochondria dysfunction.\nAbstract: Glaucoma is a group of diseases characterized by a degeneration of retinal ganglion cells (RGC) and is the second major cause of blindness worldwide. RGC vulnerability is thought to be the result of the interaction among mechanical, vascular, metabolic and neurodegenerative processes which progressively lead to RGC and optic nerve axon death. Clinical data show that glaucoma risk increases with age (A) and is higher in subjects with African-American (AA) than White-European (WE) descent. However, no quantitative mechanistic framework currently explains how A, race and ethnicity (\u03c7) interact with cellular metabolism to influence RGC vulnerability, limiting our ability to predict which individuals are at highest risk or to identify metabolic pathways to be targeted therapeutically. To fill this gap, we propose a differential model of how the concentration of RGC mitochondria (MITO) metabolism products vary with time, A and \u03c7. We represent the MITO synthase rate of adenosine triphosphate (ATP) as an exponentially decaying function of A and define the metabolic efficiency \u03b7MITO as the ratio of the stationary ATP concentration and its reference value. Simulation results indicate that \u03b7MITO decreases with A, with a maximum decrease of 37.84% and 32.4% for AA and WE subjects, respectively. Model predictions are consistent with clinical observations indicating higher glaucoma prevalence and severity in older individuals and in specific population groups, and strengthen the view of glaucoma as a multifactorial neurodegenerative disease in which metabolic vulnerability may represent one contributing pathway.\n\nID: 42117799\nTitle: Gut Microbiota-Derived Propionate: A Potential Therapeutic Target for Diabetic Retinopathy via Regulating the Gut-Retina Axis.\nAbstract: Diabetic retinopathy (DR), a prominent microvascular impairment arising from diabetes, causes substantial visual dysfunction. Emerging evidence indicates that intestinal dysbiosis promotes DR progression via the gut-retina axis. Short-chain fatty acids serve a critical function in regulating gut microbiota, and propionate, a vital member of them, has potential translational value in DR prevention and management through the gut-retina axis. This review summarizes the impact of propionate on the retinal microenvironment by regulating gut microbiota and metabolites, focusing on its mechanisms influencing DR development, including modulating inflammation, protecting blood vessels, regulating immunity, exerting neuroprotection, and combating oxidative stress. It provides insights for devising propionate-based therapeutic strategies against DR.\n\nID: 42059115\nTitle: Glucagon-Like Peptide-1 Receptor Agonists and Ocular Outcomes: Metabolic Transition, Retinal Vulnerability, and Risk-Stratified Monitoring.\nAbstract: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and dual incretin-based therapies provide marked reductions in glycosylated hemoglobin (HbA1c), body weight, and cardiovascular risk. As global adoption expands and recognition of their broad metabolic benefits grows, clinical attention is shifting toward potential secondary complications, including ocular manifestations, during rapid metabolic improvement. This narrative review synthesizes evidence from randomized trials, meta-analyses, and observational studies up to 2026 to evaluate the effects of GLP-1-based therapies on various ocular outcomes. Recent meta-analyses demonstrate an overall neutral long-term risk for diabetic retinopathy (DR) and macular edema. Transient early worsening of DR occurs primarily in patients with advanced baseline disease and rapid HbA1c reductions, reflecting a metabolic transition phenomenon rather than intrinsic retinal toxicity. This interpretation is supported by 2024 cardiovascular outcome data in a non-diabetic population (e.g., Semaglutide Effects on Cardiovascular Outcomes in People with Overweight or Obesity [SELECT] trial) that showed no increased ocular risk. Observational data suggest protective associations with glaucoma via intraocular pressure-independent neuroprotection and a reduced risk of incident age-related macular degeneration, but a potential safety signal for nonarteritic anterior ischemic optic neuropathy has emerged in recent datasets. Although the absolute incidence remains low, risk with a delayed temporal pattern appears to be increased in specific cohorts. Emerging evidence also suggests potential benefits in ocular surface homeostasis and uveitis. Accordingly, following a 2025 multidisciplinary expert consensus, risk-stratified ophthalmic monitoring, rather than routine treatment avoidance, is recommended during the early metabolic transition in high-risk diabetic patients.\n\nID: 42044330\nTitle: Hopx(+) optic nerve head-astrocytes counter neuronal stress and glaucoma damage.\nAbstract: Retinal ganglion cell (RGC) axons form the optic nerve (ON). Numerous age-related ON diseases, including glaucoma, the second most common cause of worldwide blindness, result from multiple RGC stressors. Nearly all ON astrocytes in the optic nerve head (ONH): the junctional region between the ON and the retina in young-adult rodents expresses the homeodomain only (Hopx) protein. Hopx(+) ONH astrocytes are depleted during aging. ONH primary cultures which include Hopx(+) astrocytes secrete extracellular vesicles (ONH-EVs) which selectively enhance RGC survival and neurite extension in culture, while extracellular vesicles (EVs) secreted from distal ON cultures lacking Hopx(+) astrocytes do not. ONH-EVs also enhance RGC survival in vivo in a rodent model of glaucoma. Combining rat ONH single-cell (scRNA-seq) sequencing with EV proteomic analysis, we identified ONH-Hopx(+) astrocyte secreted factors. We interrogated the online Broad institute scRNA-seq database for rat RGC gene expression in control animals and following rodent ON crush, an RGC stress model, to correlate ONH-astrocyte secreted factors with RGC gene expression changes. Following stress, RGCs upregulate the complementary pathways involving Hopx(+) astrocytic-associated factors, suggesting reciprocal communication. Using a highly selective transgenic Hopx-cre ONH knockdown strategy, we demonstrate that eliminating Hopx(+) astrocytes also results in upregulation of RGC stress responses. Our results implicate age-related loss of young ONH-astrocytes as a crucial factor in the development of age-related optic nerve diseases, and discuss replacing ONH associated factors as a paradigm shift for ON disease treatment.\n\nID: 42033725\nTitle: Spatially local inhibition and synaptic plasticity together enable dynamic, context-dependent integration of parallel sensory pathways.\nAbstract: Retinal ganglion cells have traditionally been grouped into cells that are sensitive to luminance but not spatial structure and cells with responses that are enhanced by spatial structure. Neither category describes mouse Off-transient alpha cells, which respond strongly to spatially homogeneous inputs and are suppressed by spatial structure. We identified two circuit mechanisms that together can explain this unusual spatial selectivity. First, the inhibition that controls responses of these cells is tuned to finer spatial structure than excitation, causing the balance of excitation and inhibition to depend on spatial scale. Second, the excitatory synapses onto these cells undergo strong synaptic depression, and the modulation of that depression by presynaptic inhibition amplifies responses to the transition from spatially structured to homogeneous inputs. A spatiotemporal computational model incorporating these circuit features quantitatively recapitulates the observed responses. These findings reveal how localized inhibition and short-term plasticity jointly create the distinctive spatial selectivity of Off-transient cells.\n\nID: 42032995\nTitle: [Geniposide inhibits retinal cell apoptosis induced by glaucoma through the Hspa1a pathway].\nAbstract: Glaucoma is the leading cause of irreversible blindness worldwide. Reducing intraocular pressure is currently one of the most effective treatment strategies; however, it cannot completely prevent retinal ganglion cells (RGCs) death and the resulting vision loss. Traditional Chinese medicine has been widely investigated in glaucoma treatment. This study aims to determine whether geniposide can effectively inhibit retinal cell death and to explore its potential role in glaucoma therapy. Cell experiments: Retinal R28 cells were divided into a control (CTL) group, an oxygen-glucose deprivation/reoxygenation (OGD/R) group, an OGD/R+geniposide (OGD/R+ Gen) group, and an OGD/R+Gen+heat shock protein family A member 1A (Hspa1a) small interfering RNA (OGD/R+Gen+H-KD) group. Proteomics analysis was first performed to identify key molecules altered after geniposide intervention. Quantitative real-time PCR (qPCR) and Western blotting were used to detect molecular changes after geniposide and H-KD interventions. Cell viability and death were assessed using cell counting kit-8 (CCK-8) and lactate dehydrogenase (LDH) assays. Flow cytometry, reactive oxygen species (ROS) detection, and terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining were used to evaluate apoptosis. Animal experiments: SD rats were divided into a sham control (CTL) group, an acute high intraocular pressure (aHIOP) group, an aHIOP+Gen group, and an aHIOP+Gen+Hspa1a inhibitor apoptozole (aHIOP+Gen+Apo) group. Hematoxylin-eosin (HE) staining, TUNEL staining, and flash electroretinogram (fERG) were used to evaluate retinal structure, apoptosis, and functional changes. 1) Proteomics combined with qPCR and Western blotting showed that Hspa1a expression was significantly increased after geniposide treatment. 2) Compared with the OGD/R group, the OGD/R+Gen group showed increased cell viability (P<0.05), fewer dead cells (P<0.05), decreased ROS levels (P<0.001), and reduced apoptosis (P<0.05), indicating that geniposide alleviated OGD/R-induced retinal R28 cell injury and death. 3) Compared with the OGD/R+Gen group, the OGD/R+Gen+H-KD group showed decreased phosphorylated protein kinase B (Akt, p-Akt) expression (P<0.01), reduced cell viability (P<0.05), increased cell death (P<0.05), elevated ROS levels (P<0.01), and increased apoptosis (P<0.05), suggesting that Hspa1a regulates the Akt pathway and mediates the protective effect of geniposide on retinal R28 cells. 4) Compared with the CTL group, the aHIOP group showed reduced retinal thickness (P<0.01), increased apoptosis (P<0.001), and decreased fERG b-wave amplitude (P<0.001). Compared with the aHIOP group, the aHIOP+Gen group showed increased retinal thickness (P<0.05), reduced apoptosis (P<0.05), and increased fERG b-wave amplitude (P<0.05). Compared with the aHIOP+Gen group, the aHIOP+Gen+Apo group showed decreased retinal thickness (P<0.05), increased apoptosis (P<0.05), and reduced fERG b-wave amplitude (P<0.05), indicating that geniposide alleviates aHIOP-induced retinal injury through the Hspa1a pathway. Geniposide inhibits OGD/R- and aHIOP-induced retinal cell apoptosis and tissue injury through the Hspa1a-Akt pathway, providing a potential therapeutic target for glaucoma treatment. \u76ee\u7684:

42004959\nTitle: Dual immune armies in glaucoma: microglia and monocyte-derived macrophages.\nAbstract: Glaucoma is a leading cause of irreversible blindness globally, with the core pathological feature being progressive degeneration of retinal ganglion cells. Neuroinflammation pervades the entire course of glaucoma, and an imbalance in the intraocular immune microenvironment is critical factor underlying progression. As an extension of the central nervous system, the retina has a unique immune microenvironment. Under physiological conditions, microglia, which are primary tissue-resident immune cells, maintain homeostasis. In pathological states, the blood-retinal barrier is compromised and allows monocyte-derived macrophages (MDMs) to infiltrate the retinal tissue. We introduce the concept of \"dual immune armies, \" specifically referring to the core retinal immune population comprising microglia and MDMs. These two cell types coordinate to form an immune network, but they demonstrate significant functional heterogeneity during glaucoma pathogenesis. Microglia act as first responders and activate rapidly during the early stages of injury, monitor changes in the microenvironment in real time, and initiate the primary inflammatory response. MDMs serve as \"late-reinforcement troops\" and infiltrate extensively following blood-retinal barrier disruption, amplify the inflammatory cascade, and exacerbate optic nerve damage. Previous studies have often conflated these two cell types, leading to a lack of precise targets for immune intervention in glaucoma. Based on recent research, this study systematically compared the origins, functions, and specific marker profiles of microglia and MDMs with a focus on elucidating their synergistic roles and functional division of labor in glaucomatous optic neuropathy. Elucidating the heterogeneity of these two immune cell populations and their precisely regulated functions at different disease stages will help clarify the key mechanisms underlying the imbalance of the retinal immune microenvironment in glaucoma. It will also provide a new theoretical basis and research direction for the development of targeted immunomodulatory strategies to protect retinal ganglion cells and potentially reverse optic nerve damage.\n\nID: 41997056\nTitle: Engineered mesenchymal stem cell-derived extracellular vesicles attenuate acute glaucoma-induced neuroinflammation by reprogramming microglial polarization.\nAbstract: Retinal microglia-mediated neuroinflammation is a critical driver of pathological damage in glaucoma, leading to irreversible loss of retinal ganglion cells (RGCs). Current treatments remain limited in effectively targeting and modulating this neuroinflammatory component within the retinal microenvironment. To address this, we engineered cRGD peptide-functionalized mesenchymal stem cell (MSC)-derived extracellular vesicles (cRGD-EVs) capable of actively targeting activated microglia for the localized delivery of anti-inflammatory miRNAs. After intravitreal administration, cRGD-EVs demonstrated enhanced accumulation in the retina and specific uptake by activated microglia in a rat model of retinal ischemia/reperfusion (RIR) injury. Both in vitro co-culture models and in vivo analyses confirmed the targeting efficacy and phenotypic reprogramming of microglia from a pro-inflammatory (M1) to an anti-inflammatory (M2) state. Intravitreal injection of cRGD-EVs loaded with key miRNAs (let-7c-5p, miR-21a-5p, and miR-146a-5p) significantly suppressed NF-\u03baB pathway activation and reduced the expression of downstream pro-inflammatory cytokines. Treated animals exhibited notable preservation of retinal structure, increased RGC survival, and significant recovery of visual function, as measured by electroretinography. Furthermore, in acute ocular hypertension model, cRGD-EV treatment attenuated glaucomatous neurodegeneration and improved overall retinal homeostasis. These findings highlight cRGD-EVs as a promising targeted biologic delivery system for treating neuroinflammatory components of glaucoma and potentially other retinal diseases characterized by microglial activation.\n\nID: 41975624\nTitle: M\u00fcller glial cells for regeneration, retinal organoids, cell transplantation, and neuroprotection.\nAbstract: M\u00fcller glial cells are essential for retinal structure and homeostasis and increasingly recognized as dual regulators of retinal degeneration and regeneration. Beyond providing metabolic and structural support, M\u00fcller glial cells actively shape disease progression while retaining latent regenerative potential. Growing evidence highlights their roles in retinal degeneration, development, and neuroprotection, particularly in age-related macular degeneration, diabetic retinopathy, and inherited retinal disorders. This review integrates recent advances across five key areas: (1) M\u00fcller glial cell dysfunction in retinal disease pathology, including gliosis, inflammatory signaling, and vascular dysregulation; (2) their regenerative capacity, with a critical appraisal of efforts to reprogram M\u00fcller glial cells into retinal progenitors in mammalian models and the ongoing controversy surrounding functional neuronal replacement; (3) their contribution to the maturation of induced pluripotent stem cells-derived retinal organoids; (4) their neuroprotective roles through antioxidant, immunomodulatory, and trophic mechanisms; and (5) their emerging applications in cell-based therapies. By highlighting unresolved knowledge gaps-particularly the molecular barriers limiting M\u00fcller glial cell reprogramming and the signals governing their switch between protective and pathogenic states, this review positions M\u00fcller glial cells as central targets for future retinal regenerative and therapeutic strategies.\n\nID: 41967665\nTitle: A hybrid framework for effective microscopic cell counting segmentation integrating Light-U-net with watershed.\nAbstract: Glaucoma is a major cause of irreversible blindness worldwide, resulting in the progressive degeneration of retinal ganglion cellss (RGCs), which makes early disease detection critical for effective management. Traditional methods for monitoring RGCs are labor-intensive and prone to errors. To address this, we propose Light-U-Net, a lightweight and scalable deep learning model designed to segment RGCs in retinal images. The model is trained and tested on a publicly available synthetic dataset as well as a self-generated real dataset. Additionally, we introduce a local maxima algorithm for counting RGCs based on generated annotations. A comparative analysis of various cell counting methods was performed, demonstrating that Light-U-Net combined with the watershed algorithm delivers superior segmentation and counting performance. These findings highlight the potential of Light-U-Net for automating RGC segmentation and counting, reducing errors, and improving efficiency compared to traditional approaches. Light-U-Net, in combination with watershed-based counting, provides an effective tool for glaucoma detection and monitoring, making it valuable for both disease progression tracking and treatment assessment.\n\nID: 41954904\nTitle: Clinical and Genetic Spectrum of ACO2-Linked Dominant Optic Atrophy.\nAbstract: Aconitase 2 (ACO2) gene variants are one of the most frequent causes of dominant optic atrophy (DOA). However, the associated phenotypes and genotypes still lack proper characterization. To characterize the clinical and genetic spectrum of ACO2-related DOA and evaluate genotype-phenotype correlations. This was a retrospective case series to describe the ophthalmological examination of novel DOA cases with a heterozygous ACO2 variant. Data were collected from 13 reference centers in ophthalmology from France and Great Britain between January 2021 and September 2025. Included participants were those patients with OA and confirmed heterozygous or compound heterozygous ACO2 variants. DOA cases with a heterozygous ACO2 variant. Positive molecular diagnosis for ACO2 variants by next-generation sequencing, clinical examination including age at diagnosis, sex, best-corrected visual acuity (BCVA), retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) thickness, visual field mean deviation (MD), and fundus examination. Data for 55 patients (median [IQR] age at diagnosis for 45 patients, 24 [8-51] years; 33 male [67%]) from 37 families with ACO2 variants were compiled. Analyses were conducted on 49 patients who were strictly heterozygous or compound heterozygous with the c.220C>G benign variant. Clinical data disclosed a high variability of severity, from pauci-symptomatic up to legal blindness. Median BCVA was 0.46 logMAR (Snellen equivalent, 20/63; IQR 0.00-0.89; n\u2009=\u200945). Four patients exhibited retinal abnormalities: 3 displayed a foveopathy, and 1 had retinitis pigmentosa. There were 12 previously unreported variants (to the authors' knowledge), including the deletion of ACO2 exon 9. No correlation between BCVA and sex, age at diagnosis (Spearman \u03c1\u2009=\u2009-0.19; 95% CI, -0.45 to 0.07), or variant type (Kruskal-Wallis test P =.33) was found, but there was a correlation between BCVA and RNFL (Spearman \u03c1\u2009=\u2009-0.74; 95% CI, -0.85 to -0.54), GCL (Spearman \u03c1\u2009=\u2009-0.60; 95% CI, -0.79 to -0.30), and MD (Spearman \u03c1\u2009=\u2009-0.65; 95% CI, -0.89 to -0.31). RNFL correlated with GCL (Spearman \u03c1\u2009=\u20090.69; 95% CI, 0.42-0.87) and MD (Spearman \u03c1\u2009=\u20090.57; 95% CI, 0.14-0.85); age at diagnosis correlated with GCL (Spearman \u03c1\u2009=\u2009-0.37; 95% CI, -0.63 to -0.03). Results of this case series reveal the high clinical heterogeneity among patients with ACO2-related DOA and demonstrated that some of these patients can also exhibit retinal abnormalities. In addition, there was a deletion of an entire ACO2 exon, emphasizing the potential importance of searching for large genomic rearrangements in patients without a molecular diagnosis. These findings support further studies to explain clinical variability, as no genotype-phenotype correlation was encountered.\n\nID: 41952895\nTitle: Pulsed synchrony regulation of intraocular and cerebrospinal fluid pressure: a novel paradigm for glaucoma pathogenesis and treatment.\nAbstract: Glaucoma, the leading cause of irreversible blindness worldwide, is characterized by the progressive loss of retinal ganglion cells (RGCs) and their axons. While elevated intraocular pressure (IOP) is a core risk factor, the pathogenesis of normal-tension glaucoma (NTG) remains unclear, as static IOP is within the normal range. Based on circadian fluctuations of IOP and cerebrospinal fluid pressure (CSFP), and the pressure-dependent function of the ocular glymphatic system, we propose the \"dynamic trans-lamina cribrosa pressure difference (TLCPD) imbalance\" hypothesis. This hypothesis posits that optic nerve damage may stem from abnormal pulse synchrony between IOP and CSFP (phase mismatch, amplitude mismatch, or abnormal frequency) rather than static TLCPD elevation alone, pending further validation. Dynamic imbalance induces RGC injury through dual mechanisms: mechanical stress on the lamina cribrosa (collagen fiber rupture, astrocyte activation) and metabolic dysfunction (ocular glymphatic clearance impairment, toxic waste accumulation), which ultimately converge on the activation of the programmed axonal degeneration (PAD) pathway-a conserved final common effector of RGC axon loss. Phase mismatch is the core pathological pattern in NTG. In contrast, high-tension primary open-angle glaucoma (POAG) is characterized mainly by amplitude mismatch and abnormal frequency, with potential coexistence and mutual influence of these mechanisms. Verifiable clinical (24-h IOP-CSFP synchronous monitoring) and animal experiments are proposed. This hypothesis may help explain unresolved clinical phenomena, provides novel diagnostic markers (a transient peak in TLCPD) and therapeutic strategies (CSFP regulation, glymphatic function enhancement, modulation of the PAD pathway), and opens new avenues for personalized glaucoma management.\n\nID: 41951017\nTitle: Mitochondria transplantation preserves retinal ganglion cells and promotes CNS axonal regeneration.\nAbstract: Mitochondrial dysfunction is a central driver of retinal ganglion cell (RGC) loss in glaucoma and other forms of optic neuropathies, leading to irreversible blindness. Here, we demonstrate that replenishing the mitochondrial pool through exogenous mitochondrial transplantation (\"mitotherapy\") in adult mice not only preserves neuronal survival but also promotes regenerative competence in the central nervous system (CNS). In aging or injured RGCs, we identified profound deficits in mitochondrial biogenesis, fission-fusion balance, and mitophagy. Transplantation of functional mitochondria in in vitro models of trophic deprivation and glutamate excitotoxicity restored mitochondrial homeostasis, improved energy production, reduced reactive oxygen species, enhanced RGC survival, and drove robust neurite outgrowth, with transplanted mitochondria actively trafficking to growth cones. This effect was dampened following inhibition of mitochondrial fusion, indicating a pivotal role of fusion-dependent functional integration of exogenous mitochondria. Strikingly, intravitreal delivery of mitochondria in an optic nerve crush model of adult mice enabled their integration into RGCs, improved survival and electrophysiological responses, and supported axonal regeneration across the lesion site. These findings indicate that mitochondrial transplantation strategy rescues bioenergetic failure and supports a pro-regenerative activity of neurons, highlighting the potential of mitotherapy as a transformative approach for neurodegenerative eye diseases and CNS injuries.\n\nID: 41938136\nTitle: A dual-responsive CO-releasing nanogel ameliorates retinal ischemia-reperfusion injury by restoring mitochondrial homeostasis and attenuating cGAS-STING pathway activation.\nAbstract: Retinal ischemia-reperfusion injury (RIRI) represents a central pathological mechanism underlying neurodegeneration in multiple blinding ocular diseases, including glaucoma, diabetic retinopathy, and retinal vein occlusion. Ischemic stress triggers a surge of reactive oxygen species (ROS) within retinal ganglion cells, leading to mitochondrial dysfunction and initiating a vicious cycle of cellular damage. Targeting the regulation of redox balance within the RIRI microenvironment to restore mitochondrial homeostasis remains a major challenge in RIRI therapy. Here, a dual ROS-responsive carbon monoxide (CO) prodrug nanoplatform (COPN) was developed. This system integrates a ROS-sensitive CO-releasing molecule, CORM401, as the active prodrug unit, which is encapsulated within a disulfide-crosslinked dendritic nanogel matrix, thereby enabling site-specific CO release under pathological oxidative conditions. Locally released CO effectively neutralizes excessive ROS, restores mitochondrial quality control, and prevents mitochondrial DNA cytosolic leakage, thereby attenuating cGAS-STING pathway activation and subsequent neuroinflammatory responses. Furthermore, COPN successfully reverses ischemia-induced immunometabolic dysregulation, restores oxidative phosphorylation capacity, and enhances cellular metabolic resilience. This study offers a promising therapeutic strategy with strong translational potential for treating oxidative retinal diseases.\n\nID: 41929112\nTitle: Variant-to-gene mapping identifies ARHGEF12 as a primary open-angle glaucoma effector gene operating within retinal ganglion cells.\nAbstract: Primary open-angle glaucoma (POAG), a leading cause of irreversible blindness, has a strong genetic basis. The Primary Open-Angle African Ancestry Glaucoma Genetics study previously identified 46 risk loci. To pinpoint causal variants and their corresponding effector genes, we analyzed gene expression, chromatin accessibility, and conformation in two ocular cell-types: trabecular meshwork cells (hTMCs) and retinal ganglion cells derived from induced pluripotent stem cells (hiPSC-RGCs). We identified 24 candidate genes in hTMCs and 56 in hiPSC-RGCs. The ARHGEF12 gene was selected for further validation because it was nominated by local and distal promoter interactions in both cell-types and has reproducible prior evidence of its association with POAG. While its role in hTMCs is established, its function in RGCs is unclear. hiPSC-RGCs generated from a POAG donor homozygous for the risk allele showed reduced ARHGEF12 expression, altered morphology, and disrupted neuronal activity. This framework enables functional evaluation of additional POAG risk variants.\n\nID: 41915053\nTitle: Short-term natural history of non-perfusion areas in treatment-naive diabetic retinopathy patients using swept-source OCT angiography.\nAbstract: \n\nID: 42422405\nTitle: Neuroprotective Effects of Ethiopian Coffee Beans against Hyperglycemia-induced Brain Injury in Rats.\nAbstract: At least 50% of people with diabetes suffer from one or more complications if their conditions are not adequately managed over time. Diabetic neuropathy is one of the prevalent complications of diabetes, which also includes diabetic nephropathy, retinopathy, cardiomyopathy, and diabetic foot diseases. The present study evaluated the protective effects of Ethiopian coffee beans (Coffea arabica) against glucose-induced brain tissue injury using in\u00a0vitro, ex\u00a0vivo, and in silico experimental models. Oxidative injury was induced by incubating brain tissue collected from normal male Sprague-Dawley rats in glucose solution and treated with the different concentrations of Ethiopian coffee bean extracts (hot and cold aqueous) for 2\u2009h at 37\u00b0C in a 95% O2 and 5% CO2 incubator. Induction of glucose-mediated (0.0111\u2009M glucose) oxidative injury led to significant depletion of reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), and total glycogen levels, while elevating malonaldehyde (MDA), nitric oxide (NO), glycogen phosphorylase, fructose-1,6-bisphosphatase, ATPase, and acetylcholinesterase (AChE) activity levels. Treatment with different concentrations of the aqueous extracts of coffee beans significantly restored the levels and activities of the biomarkers mentioned above. LC-MS analysis indicates the presence of chlorogenic acid (CGA), caffeic acid, quinic acid, caffeine, Cafestol, Kahweol, ferulic acid, and catechol in the coffee extracts. In silico analysis revealed a strong molecular interaction between CGA and the CAT, SOD, and AChE enzymes. The data from this study suggest that bioactive compounds from Coffea arabica have a potential neuroprotective effect against glucose-mediated oxidative neurodegeneration in rat brain tissue.\n\nID: 42352347\nTitle: L-Serine Attenuates Metabolic and Behavioural Features of Diabetic Neuropathy with Dose-Dependent Central Proteomic Correlates in a Rat Model.\nAbstract: Diabetic neuropathy (DN) is a multifactorial complication of diabetes mellitus driven by chronic hyperglycemia, insulin resistance, and disturbed metabolic homeostasis, leading to progressive injury of both the peripheral and central nervous systems. This study investigated whether L-serine supplementation could attenuate DN through dose-dependent metabolic and neuroprotective mechanisms in a high-fat diet (HFD) plus streptozotocin (STZ)-induced diabetic rat model. Male Wistar rats (n = 8 per group) were allocated to five groups: normal control (NC), diabetic control (DC), pioglitazone (PIO; 1.5 mg/kg/day), low-dose L-serine (S1; 200 mg/kg/day), and high-dose L-serine (S2; 400 mg/kg/day). After 60 days of oral gavage, behavioural testing, glucose and insulin profiling, HOMA-IR calculation, brain histopathology, nerve growth factor (NGF) immunohistochemistry, and LC-MS/MS-based proteomic analysis of cerebral tissue were performed. Diabetic rats exhibited marked hyperglycaemia (355.33 \u00b1 4.72 mg/dL), hyperinsulinaemia, severe insulin resistance (HOMA-IR 16.8 \u00b1 3.2; a 14-fold increase), impaired thermal nociception, motor dysfunction, and pronounced neuronal degeneration. L-serine supplementation significantly improved metabolic status: S1 reduced HOMA-IR by 77.4% and S2 by 87.5% relative to diabetic controls (p < 0.001). High-dose L-serine produced greater improvements in thermal sensitivity, motor coordination (rotarod latency 26.67 \u00b1 1.52 s vs. 16.1 \u00b1 0.85 s in DC; p < 0.05), and NGF expression (8.6-fold increase vs. DC). Histopathology confirmed attenuation of neuronal injury and gliosis in both treatment groups. Exploratory, group-level proteomic profiling identified dose-specific molecular signatures: S1 was predominantly associated with carbohydrate, lipid, and biosynthetic pathways, whereas S2 was associated with synaptic, neurotransmission-related, and proteostasis pathways. Within the constraints of an exploratory design-group-level pooled proteomics, analysis of cerebral rather than peripheral-nerve tissue, and only two doses-these findings indicate that L-serine attenuates the metabolic and behavioural features of experimental diabetic neuropathy and generates the testable hypothesis of dose-dependent neuro-metabolic remodelling. The proteomic signatures are hypothesis-generating and require orthogonal validation before any mechanistic or translational inference can be drawn.\n\nID: 42321202\nTitle: Interdependent roles of PKM2 in photoreceptors and RPE: implications for retinal degeneration.\nAbstract: Pyruvate kinase M2 (PKM2) functions as both a glycolytic enzyme and a transcriptional co-activator that coordinates metabolism and cell survival. Here, we define the developmental timing, cellular distribution, and physiological role of PKM isoforms in the mouse retina. PKM2 expression begins at postnatal day 2, preceding PKM1, and is highly enriched in photoreceptors, whereas PKM1 predominates in retinal ganglion cells. Conditional deletion of PKM2 in the retina, rods, or retinal pigment epithelium (RPE) demonstrated that PKM2 is essential for maintaining retinal structure and function. Loss of PKM2 impaired glycolytic activity, decreased ATP generation, and disrupted metabolic balance, leading to cellular disorganization and degeneration in both photoreceptors and the RPE. In the RPE, PKM2 deficiency decreased RPE65 protein levels and impaired the regeneration of 11-cis-retinal, disrupting the visual cycle. PKM2 deletion disrupted the normal cone opsin gradient, indicating that PKM2-dependent metabolic and transcriptional functions are essential for maintaining proper cone organization in the retina. Moreover, rod-specific deletion of PKM2 in Abca4 mutant mice showed early signs of retinal degeneration. The studies described in this manuscript highlight the interdependence of photoreceptor and RPE metabolism and show that PKM2 plays an important role in retinal energy homeostasis and neuronal survival, providing insight into the mechanisms underlying photoreceptor and RPE degeneration in age-related macular degeneration.\n\nID: 42194098\nTitle: Uridine Improves Locomotor Activity and Sciatic Nerve Integrity in a Mouse Model of Diabetes Mellitus.\nAbstract: Diabetic peripheral neuropathy is an important cause of functional disability, and current therapies have limited ability to halt its progression. Uridine, a pyrimidine nucleoside essential for the synthesis of membrane phospholipids and neuronal metabolism, appears to be a potential neuroprotective agent, but its impact on motor behavior and peripheral nerve integrity in diabetes remains insufficiently investigated. Our study investigated the effects of chronic uridine supplementation on locomotor performance, neuromuscular electrophysiological manifestations, and morphological changes in the sciatic nerve in a murine model of streptozotocin-induced diabetes. We used male C57BL/6 mice (n = 8/group) that were assigned to three groups: sham (no diabetes), diabetic (streptozotocin-induced, diabetes mellitus, DM+), and diabetic treated with uridine (DM+U). We observed that uridine did not alter the metabolic status, as the HbA1c values remained comparable between diabetic groups (9.93 \u00b1 0.57% DM+ vs. 9.71 \u00b1 0.55% DM+U; p = 0.72), suggesting effects independent of glycemic control. The open field test revealed that diabetic mice showed a marked reduction in spontaneous locomotion, while uridine-treated mice maintained a significantly higher level of activity (longer total distance traveled 3761.7 \u00b1 789.1 cm vs. 2477.5 \u00b1 1017.6 cm in DM+; p = 0.023). Electrophysiological evaluation revealed near-normal sciatic nerve function in DM+U mice, including higher compound motor action potential (CMAP) amplitudes (10.21 \u00b1 0.64 mV vs. 5.75 \u00b1 0.72 mV; p < 0.0001) and reduced F-wave latency (6.35 \u00b1 0.45 ms vs. 7.29 \u00b1 0.31 ms; p < 0.0001). Histological and immunohistochemical analyses (PGP 9.5) further confirmed reduced nerve degeneration in DM+U mice. Our data suggest that chronic uridine administration may confer both functional and structural neuroprotection in diabetic neuropathy, even in the absence of improved glycemic control.\n\nID: 42117585\nTitle: Fenofibrate and progression of retinopathy in adults with diabetes: the randomised placebo-controlled LENS trial.\nAbstract: Diabetic retinopathy is a leading cause of visual loss. Hypothesis-generating data from cardiovascular outcome trials suggest that fenofibrate therapy may reduce the progression of diabetic retinopathy. To determine whether treatment with fenofibrate reduces the progression of diabetic retinopathy. We conducted a parallel-group, double-masked, placebo-controlled clinical trial of fenofibrate. A web-based algorithm allocated participants to treatment arms by minimisation. The trial was positioned within NHS Scotland's Diabetic Eye Screening Programme. Adults with diabetes and non-referable retinopathy or maculopathy (based on Diabetic Eye Screening retinal image grading) were eligible. Study treatment was mailed to participants' homes. Participants who were eligible at the screening assessment entered an active pre-randomisation run-in during which they took 145\u2005mg fenofibrate. After randomisation, participants received 145\u2005mg fenofibrate tablets or placebo. Study treatment was taken daily in those with normal renal function, or on alternate days in those with impaired renal function. The primary outcome was a composite of developing referable diabetic retinopathy or maculopathy, or requiring treatment for diabetic retinopathy or maculopathy. Incremental cost-effectiveness was assessed in terms of the primary outcome and per modelled quality-adjusted life-year gained. Data were obtained from 6-monthly interviews by research nurses and linkage to national healthcare data sets. Selected adverse events were adjudicated by study clinicians masked to treatment allocation. One thousand four hundred and eighty-four participants entered the pre-randomisation run-in, of whom 1151 were randomised. The primary outcome occurred in 131 (22.7%) of 576 participants assigned fenofibrate and 168 (29.2%) of 575 participants assigned placebo (hazard ratio 0.73; 95% confidence interval 0.58 to 0.91; p\u2005=\u20050.006) over a median of 4.0 years. Any progression of retinopathy or maculopathy, and development of macular oedema were also reduced. There was no effect on visual function, quality of life, or visual acuity. Fenofibrate use resulted in a non-significant reduction in 6-monthly health service costs (mean difference -\u00a3101, 95% confidence interval -\u00a3243 to \u00a342), leading to dominance over standard care and a high probability of cost-effectiveness. Based on modelling (assuming no difference in background healthcare costs by treatment allocation), fenofibrate led to a small increase (\u00a36) in cost for a small gain (0.02) in quality-adjusted life-years; incremental cost-effectiveness ratio \u00a3406 per quality-adjusted life-year gained. The probability of cost-effectiveness was 79-86% at thresholds of \u00a320,000-30,000 per quality-adjusted life-year gained. Early Treatment Diabetic Retinopathy Study retinopathy grading is considered the gold standard, but it is not used in large-scale retinal screening programmes; Diabetic Eye Screening grading is based on Early Treatment Diabetic Retinopathy Study but is less granular. Fenofibrate was clinically effective and cost-effective for reducing the progression of diabetic retinopathy compared with placebo among participants with early retinal changes. LENS participants will be followed for 10 years to assess the long-term effects of fenofibrate therapy. This synopsis presents independent research funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme as award number 14/49/84. Diabetes can affect the inner layer at the back of the eye, a condition called diabetic retinopathy. Many people need to see a National Health Service eye specialist or need treatment for diabetic eye disease. Each year, diabetic retinopathy leads to 1500 people being certified as blind in the United Kingdom. This makes it a leading cause of blindness in working age adults. Fenofibrate is a drug that is sometimes used to lower cholesterol. Two studies from the 2000s suggested that fenofibrate may lower the risk of diabetic eye disease getting worse. However, those results were not convincing enough to change how doctors treat their patients. We ran the Lowering Events in Non-proliferative retinopathy in Scotland study to find out if fenofibrate may be useful for treating people with diabetic eye disease. Lowering Events in Non-proliferative retinopathy in Scotland was a large clinical trial. We studied 1151 adults with early diabetic eye disease from across Scotland. Participants came to a research clinic at the start to check if they were eligible. Study treatment was sent to peoples\u2019 homes by post. Half the people in the study took fenofibrate tablets. The other half took placebo (i.e. dummy) tablets. Nobody knew which treatment they were getting. Research nurses phoned them every 6 months over the next 4 years. The study team used information from these calls and from National Health Service records to find out what happened to participants. We found that the people taking fenofibrate had a lower chance of their diabetic eye disease getting worse compared to those taking placebo. Fewer people taking fenofibrate needed to see a National Health Service specialist, have treatment for eye disease or developed swelling at the back of the eyes (called macular oedema) compared to placebo. We now have better evidence about the positive effect fenofibrate in patients with early diabetic eye disease, and the potential for savings to the National Health Service.\n\nID: 42092483\nTitle: JNK inhibition suppresses microglial NLRP3 activation and oxidative stress but unexpectedly worsens pain in diabetic neuropathy: insights from a combined in vitro and in vivo pharmacological study.\nAbstract: Diabetic neuropathy (DN) is driven by neuroinflammation and oxidative stress, with c-Jun N-terminal kinase (JNK) as a key mediator; however, the effects of JNK inhibition on neuropathic pain remain unclear. Therefore, we investigated the therapeutic potential of the JNK inhibitor SP600125 in a type 2 diabetic mouse model using combined in vitro and in vivo approaches. BV2 microglia were exposed to high glucose, lipopolysaccharide, palmitic acid, or hydrogen peroxide (H2O2) with or without SP600125 (10\u00a0nM). The PPAR\u03b3 antagonist GW9662 was used for mechanistic dissection. Diabetic mice received SP600125 (15\u00a0mg/kg/day) or vehicle for 7 weeks. In vitro, SP600125 attenuated JNK phosphorylation and suppressed pro-inflammatory activation via NF-\u03baB and NLRP3 in a PPAR\u03b3-dependent manner. SP600125 reduced palmitate-induced oxidative stress but exacerbated H2O2-induced injury (p\u00a0<\u00a00.0001), revealing context-dependent redox modulation. In vivo, SP600125 reduced diabetes-induced lipid accumulation and microglial reactivity while shifting microglia to an anti-inflammatory phenotype; however, it did not alter NLRP3, ASC, IKK\u03b1, or PPAR\u03b3 expression. Despite these effects, SP600125 paradoxically worsened mechanical allodynia and thermal hyperalgesia. Together, these findings indicate that JNK inhibition provides anti-inflammatory and anti-lipid effects but paradoxically exacerbates pain, revealing a critical dissociation between neuroprotection and pain modulation in diabetic neuropathy.\n\nID: 41933993\nTitle: Mitochondrial transfer as a therapeutic target for peripheral neuropathy.\nAbstract: Satellite glial cells transfer mitochondria to sensory neurons via myosin 10-dependent tunneling nanotubes. Ji et al. show that this transfer is impaired in diabetic neuropathy, causing energy failure. Restoring it via cell or mitochondrial transplantation alleviates pain and promotes nerve regeneration, revealing a new therapeutic strategy for peripheral neuropathy.\n\nID: 41788812\nTitle: Nervonic acid confers neuroprotection in a zebrafish model of diabetic neuropathy by promoting myelin repair and metabolic modulation.\nAbstract: Diabetic neuropathy (DN) is one of the most common and debilitating complications of type 2 diabetes mellitus (T2DM), yet effective therapeutic strategies remain limited. Nervonic acid (NA) is recognized for its neuroprotective and anti-inflammatory properties. However, its role in DN has not been fully elucidated. In this study, we investigated the protective effects of NA against T2DM-induced DN using a zebrafish model and explored the underlying molecular mechanisms. T2DM was induced in zebrafish larvae through a high-fat, high-glucose diet combined with a low dose of streptozotocin. Larvae were subsequently treated with NA at concentrations of 125, 250, or 500\u00a0\u03bcg/mL. Motor function, myelin integrity, neutrophil infiltration, and reactive oxygen species (ROS) levels were evaluated using fluorescence imaging and histological staining. Gene expression analysis was performed by quantitative real-time PCR. Metabolomics coupled with KEGG enrichment analysis was applied to identify NA-regulated metabolic pathways. NA significantly preserved myelin integrity, reduced neutrophil infiltration, and lowered ROS levels in DN zebrafish. Expression of myelin-related genes (mbpa and mpz) was upregulated, while pro-inflammatory cytokines were downregulated following NA treatment. Metabolomic profiling revealed that NA reversed diabetes-associated dysregulation in purine metabolism, energy metabolism, vitamin B6 pathways, and redox homeostasis. Key metabolites including guanosine monophosphate, adenosine triphosphate, pyridoxal 5'-phosphate, and L-glutathione were markedly restored toward normal levels. These findings demonstrate that NA confers robust neuroprotection in DN by alleviating inflammation and oxidative stress, preserving neuronal structure and function, and reprogramming key metabolic pathways.\n\nID: 41687800\nTitle: From Observation to Prediction: Machine Learning Analysis of Progression of Visual loss in Nonarteritic Anterior Ischemic Optic Neuropathy.\nAbstract: To determine whether combinations of modifiable clinical/systemic risk factors and structured trial variables predict early disease progression in acute NAION, as a clinical-feature benchmark, using machine learning for multivariable analysis. Secondary analysis of a multicenter, double-masked, sham-controlled, randomized clinical trial. We analyzed 589 study eyes with acute NAION from 729 participants prospectively enrolled in the QRK207 trial who had separate Screening and Day 1 evaluations. Progression was evaluated at screening, Baseline, and Month 2. Only pre-treatment and placebo-group participants were included. Visual loss was modeled using best-corrected visual acuity (BCVA), defined as \u226510- or \u226515-letter loss on the Early Treatment Diabetic Retinopathy Study (ETDRS) scale, and standardized automated perimetry (SAP) using censored average total deviation (avgTD). Logistic regression, random forest, XGBoost, and support vector machine classifiers were trained with 5-fold cross-validation. Performance (AUROC, PR-AUC, accuracy, sensitivity, specificity, F1-score) and SHapley Additive exPlanations (SHAP) identified systemic and ocular predictors of visual deterioration. No features were extracted from raw OCT scans, fundus photographs, or raw visual field images; analyses were limited to structured clinical/systemic and trial-captured variables (including numeric ophthalmic measures when available). Model performance for visual function progression, and the clinical features contributing most to predicted risk. Models showed modest performance (AUROC 0.59-0.77; PR-AUC up to 0.60 varied by endpoint and prevalence). Early decline was associated with fellow-eye NAION, obstructive sleep apnea, and higher diastolic pressure, while later progression reflected metabolic and vascular stress (elevated LDH, triglycerides, blood pressure, BMI). Preserved RNFL thickness, normal renal indices, and diabetes medication use were linked to lower risk. Machine-learning models achieved modest discrimination but identified clinically relevant features distinguishing early from later NAION progression, supporting future biomarker-based and longitudinal modeling efforts. Findings suggest that improved prediction will likely require richer ophthalmic biomarkers (e.g., OCT/VF-derived features), multimodal models, and longitudinal approaches.\n\nID: 41528693\nTitle: Effectiveness of vitamin E in the treatment of diabetic neuropathy: systematic review and meta-analysis.\nAbstract: To evaluate whether tocotrienol-rich vitamin E improves nerve-conduction parameters and symptoms in diabetic peripheral neuropathy (DPN). Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses PRISMA 2020 (PROSPERO CRD420250653145), we searched the PubMed, Web of Science, Scopus, and Embase databases up until 20 March 2025, for parallel-group randomized controlled trials (RCTs) of oral vitamin E in adults (\u2265\u200918 years) with electrophysiologically confirmed DPN. Two independent reviewers performed screening, extraction, and the revised Cochrane Risk of Bias tool version 2.0 (RoB 2.0). Random-effects meta-analyses were conducted using the mean differences (MD) with 95% confidence intervals (CI). Five RCTs (n\u2009=\u2009660) met the criteria. Tocotrienol-rich vitamin E increased sural sensory nerve-conduction velocity (NCV) by 1.77\u00a0m s\u207b\u00b9 (0.80-2.74) and median sensory NCV by 1.53\u00a0m s\u207b\u00b9 (0.44-2.63); tibial motor NCV rose 1.47\u00a0m s\u207b\u00b9 (0.36-2.58) versus placebo. Nerve-action-potential amplitudes and glycated hemoglobin A1c (HbA\u2081c) were unchanged (MD -\u20090.06%, -\u20090.18-0.06). Adverse-event rates were similar between groups. Two trials had a low risk of bias; one presented some concerns. Vitamin E yielded selective NCV gains without amplitude change, suggesting preservation or remyelination of sensory fibers rather than axonal regeneration. The absence of glycemic effects indicates neuroprotection independent of glucose control, positioning vitamin E as a potential adjunct-not substitute-to antidiabetic therapy. Heterogeneity in isoform, dose, and treatment duration (\u2264\u200912 months) and modest sample sizes limit certainty. Larger, longer trials incorporating functional outcomes (pain, gait, and quality of life) are required.\n\nID: 41497475\nTitle: Targeting Retinal Neuroglial Vascular Unit Damage: Novel Therapeutic Strategies for Early-Stage Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) is a prevalent chronic ocular complication of diabetes, which ranks as the leading cause of blindness in individuals aged 40 and above. Recent studies have demonstrated that neuroglial vascular unit (NGVU) injury leads to distinct fundus changes in DR, including exudates, cotton-fluff spots, microangiomas, hemorrhages, and neovascularization. Currently, the primary clinical treatment options primarily target retinal microvascular degeneration during the middle and late stages of DR through techniques such as retinal laser photocoagulation, antivascular endothelial growth factor (VEGF) therapy, and vitrectomy. However, progression to these stages often results in irreversible damage to visual acuity with limited treatment efficacy. In recent years, relevant research has confirmed that NGVU injury occurs prior to retinal microangiopathy in patients with DR, and it is closely associated with impaired visual function. Therefore, targeting NGVU holds potential for future therapeutic interventions aimed at preventing and treating early-stage DR. This review identifies six key molecular targets (P2X7 receptor, NLRP3 inflammasome, retinal microglial cell necroptosis pathway, spermine oxidase, and AQP4-AS1 lncRNA) that mitigate NGVU dysfunction in preclinical models. Literature search was conducted in PubMed/Embase using keywords \"diabetic retinopathy,\" \"neuroglial vascular unit,\" and \"targeted therapy\" (2018-2024), focusing on preclinical studies with in vivo efficacy data.\n\nID: 41465799\nTitle: Chitosan Protects Peripheral Nerves Against Damage Induced by Diabetes Mellitus.\nAbstract: Diabetic peripheral neuropathy (DPN) is one of the most common and debilitating complications of diabetes mellitus, for which current therapies do not prevent nerve degeneration. Chitosan, a biocompatible polysaccharide with antioxidant, anti-inflammatory, and lipid-lowering properties, may exert direct neuroprotective effects. This study evaluated the impact of oral administration of chitosan on peripheral nerve function and structure in a murine model of streptozotocin (STZ)-induced diabetes. Male C57BL/6 mice were divided into three groups: Sham, untreated diabetics (T1DM) and diabetics treated with chitosan (150 mg/kg/day, 12 weeks). Metabolic, behavioral (Open Field), nociceptive (Von Frey, Tail-Flick), electrophysiological (compound motor action potential-CMAP) and histological (intraepidermal nerve fiber density-IENF) parameters were analyzed. Chitosan did not significantly modify blood glucose (p = 0.3366), but showed favorable metabolic effects, reducing LDL cholesterol in T1DM+Chitosan vs. T1DM mice (43.75 \u00b1 5.62 mg/dL vs. 82.75 \u00b1 7.65 mg/dL, p < 0.0001) as well as triglycerides (103.5 \u00b1 12.8 mg/dL vs. 175.5 \u00b1 22.8 mg/dL, p < 0.0001). In nociceptive tests, chitosan ameliorated thermal hyperalgesia (Tail-Flick: T1DM 1.25 \u00b1 0.19 s vs. T1DM+Chitosan 1.54 \u00b1 0.16 s; p = 0.0188) and mechanical allodynia (Von Frey: T1DM 0.16 \u00b1 0.07 g vs. T1DM+Chitosan 0.38 \u00b1 0.15 g, p = 0.0103). Electrodiagnostically, chitosan improved CMAP amplitude (T1DM 5.756 \u00b1 0.706 mV vs. T1DM + Chitosan 6.756 \u00b1 0.760 mV, p = 0.0409) and reduced CMAP duration (3.161 \u00b1 0.217 ms vs. 2.900 \u00b1 0.080 ms, p = 0.0273). Histologically, IENF density significantly increased in the treated group (0.01991 \u00b1 0.00246 vs. 0.01512 \u00b1 0.00253 in T1DM; p = 0.0200). Oral administration of chitosan confers functional and structural neuroprotection in STZ-induced diabetic neuropathy despite persistent hyperglycemia.\n\nID: 41397889\nTitle: Recovery of Retinal Terminal Fields after Traumatic Brain Injury: Evidence of Collateral Sprouting and Sexual Dimorphism.\nAbstract: The central nervous system is characterized by its limited regenerative potential, yet striking examples of functional recovery after injury in animal models and humans highlight its capacity for repair. Little is known about repair of pathways/circuits after traumatic brain injury (TBI), which results in disruption of connectivity. Here we utilize a mouse model of diffuse traumatic axonal injury (impact-acceleration TBI) in order to explore, for the first time, the evolution of structural and functional changes in the terminal fields of the injured visual system. Retinal ganglion cell (RGC) axons and synapses were genetically labeled via AAV transduction, while anterograde and transsynaptic tracers were used to mark terminals and postsynaptic cells. Functional connectivity and visual integrity were assessed by monitoring c-Fos expression following light stimulation and pattern-reversal visual evoked potentials (pVEPs). Our findings demonstrate that, although TAI results in an \u223c50% loss of RGC axons and terminals, surviving RGCs undergo collateral sprouting, a form of compensatory branching of surviving axons, that restores terminal density to preinjury levels. Transsynaptic tracing and c-Fos mapping confirmed the reestablishment of connectivity, which was also associated with significant improvements in visual function as measured by pVEPs. Interestingly, the recovery process exhibited sexual dimorphism, with female mice showing delayed or incomplete repair. Moreover, collateral sprouting proceeded normally in Sarm1 knock-out mice, evidence of some independence from Wallerian degeneration. Our findings show that collateral sprouting may be an important mechanism of circuit repair in TAI and may represent a promising target for therapeutic interventions.\n\nID: 41285704\nTitle: Metformin protects retinal ganglion cells in a preclinical model of retinal ischemia/reperfusion injury and stabilizes visual field in diabetic patients with glaucoma.\nAbstract: Metformin, a first-line treatment for type 2 diabetes, has gained attention as a promising neuroprotective agent due to its pleiotropic effects - including anti-inflammatory, anti-apoptotic, and autophagy-enhancing properties. Here we provide both preclinical and clinical evidence demonstrating the neuroprotective effects of metformin in the context of retinal ganglion cell (RGC) degeneration, a hallmark of glaucoma, a leading cause of irreversible blindness for which no direct RGC-neuroprotective therapies are currently available. In a mouse model of retinal ischemia/reperfusion injury systemic administration of metformin significantly prevented RGC loss and preserved retinal structure. Enhanced phosphorylation of AMP-activated protein kinase (AMPK) was observed, along with increased autophagosome formation and upregulation of key mitophagy markers - including LC3II, optineurin, and Parkin - indicating improved mitochondrial quality control mechanisms. Proteomic analysis revealed that metformin modulated several proteins implicated in mitochondrial respiratory function, ubiquitination, and intracellular trafficking, suggesting broader effects on retinal cellular homeostasis. Complementing our preclinical observations, a retrospective clinical study in diabetic patients with glaucoma showed that individuals treated with metformin maintained stable visual field (VF) parameters over a six-month period, whereas those treated with insulin exhibited significant VF deterioration. These findings position metformin as a promising intraocular pressure (IOP)-independent neurotherapeutic for slowing or preventing glaucomatous neurodegeneration.\n\nID: 41280491\nTitle: The neuroprotective role of eucalyptol in a type-2 diabetes induced neuropathy rat model.\nAbstract: Type 2 diabetes mellitus is a chronic metabolic condition that may cause diabetic neuropathy, a debilitating complication driven by chronic hyperglycemia, lipid imbalance, oxidative stress and persistent inflammation. In this study, we investigated the neuroprotective potential of eucalyptol in a streptozotocin-induced rat model of diabetic neuropathy. We found that eucalyptol treatment significantly reduced thermal and mechanical hypersensitivity, lowered blood glucose and glycated hemoglobin, improved insulin levels and favorably regulated lipid profiles by decreasing total cholesterol, triglycerides and low-density lipoprotein cholesterol (LDL-C) while increasing high-density lipoprotein cholesterol (HDL-C). Antioxidant defenses were strengthened, as evidenced by elevated superoxide dismutase, catalase and glutathione-S-transferase activities, alongside reduced malondialdehyde levels. Eucalyptol also exhibited anti-inflammatory effects by inhibiting nuclear factor kappa B (NF-\u03baB) activation and lowering tumor necrosis factor-\u03b1lpha (TNF-\u03b1) and interleukin-6 (IL-6) expression. Histopathological analysis revealed preserved neuronal cytoarchitecture and reduced degeneration in the brain, along with regeneration of \u03b2-cells and restoration of islet morphology in the pancreas. Restoration of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), both key neurotrophins supporting neuronal growth and survival, reflected enhanced neuronal survival and regeneration, further supported by electron microscopic evidence of sciatic nerve repair and remyelination. Collectively, we conclude that eucalyptol provided neuroprotection via glucose-lowering, antioxidant, anti-inflammatory and neurotrophic actions, highlighting its therapeutic potential.\n\nID: 41167570\nTitle: Neuroprotective effects of Urtica dioica Linn. on diabetic animal models: A systematic review.\nAbstract: Urtica dioica Linn. is a medicinal herb that belongs to the Urticaceae family. It is found in several countries worldwide and has numerous health-related benefits, including neuroprotection, anticancer, and anti-inflammatory effects. U. dioica has shown potential efficacy in treating diabetic neuropathy. This study aimed to systematically review the neuroprotective effects of U. dioica in diabetic models and explore the relationship between molecular and behavioral outcomes. A comprehensive search was conducted in several databases, including PubMed, Web of Science, Scopus, Science Direct, and the Cochrane Library. Only preclinical studies conducted on diabetic animal models with neural dysfunction were included. Eligible studies were required to have specific controlled groups and evaluate neural outcomes through behavioral tests or molecular investigations. Two authors independently extracted data according to the predefined inclusion and exclusion criteria. Of the 1398 studies identified, 11 met the inclusion criteria and were included in this review. U. dioica has been demonstrated to have beneficial effects in mitigating diabetes-induced neural dysfunction. These effects are likely mediated through mechanisms such as reducing oxidative stress and neuroinflammation, modulating insulin signaling pathways, and promoting neurogenesis. Evidence has shown that U. dioica consumption has positive effects on neuronal density in diabetes-affected neural tissues. Preclinical findings suggest that U. dioica consumption may protect against diabetes-associated neural dysfunction. While these results highlight its potential as a complementary strategy for mitigating diabetic neuropathy, further research, including clinical trials, is required for validation.\n\nID: 41106394\nTitle: An Insight into the Therapeutic Potential of Phytobioactives for Diabetic Neuropathy.\nAbstract: Diabetic neuropathy, a debilitating complication of diabetes, arises from chronic hyperglycemia-induced inflammation and oxidative stress, leading to progressive nerve damage. Current therapeutic strategies often focus on symptomatic relief rather than addressing the underlying pathophysiology. Emerging evidence highlights the therapeutic potential of phytobioactives with robust anti-inflammatory and antioxidant properties as promising alternatives for diabetic neuropathy management. Phytobioactives such as flavonoids, polyphenols, alkaloids, and terpenoids demonstrate significant potential by mitigating oxidative stress, inhibiting pro-inflammatory cytokines, and promoting neuroprotection. Furthermore, combination approaches utilizing the synergistic effects of these phytobioactives have shown enhanced efficacy in preclinical models, targeting multiple pathways involved in the progression of diabetic neuropathy. However, clinical translation is hindered by challenges including low bioavailability, chemical instability, and suboptimal dosage. This review explores the mechanistic roles, preclinical evidence, and clinical challenges of phytobioactives in diabetic neuropathy therapy, emphasizing the need for advanced formulation strategies and well-designed clinical trials to optimize their therapeutic potential. Leveraging these phytobioactives could pave the way for more effective and holistic diabetic neuropathy treatments.\n\nID: 41092991\nTitle: Neuromodulatory efficacy of Bacopa monniera extract against streptozotocin-induced neuronal dysfunction in SH-SY5Y cells: Implications for diabetic neuropathy.\nAbstract: Diabetic neuropathy (DN), a major complication of diabetes mellitus, is characterized by progressive neuronal damage driven by hyperglycemia-induced oxidative stress, mitochondrial dysfunction, and advanced glycation end product (AGE) accumulation. Bacopa monniera (Scrophulariaceae), enriched with the neuroactive saponin Bacoside A (BA), has demonstrated neuroprotective potential. This study explored the molecular mechanisms underlying the neuroprotective effects of B. monniera extract (BME) against streptozotocin (STZ)-induced toxicity in SH-SY5Y neuroblastoma cells. In silico ADMET analysis revealed that BA and its sapogenins possess favorable pharmacokinetic profiles, including enhanced absorption, reduced toxicity, and improved clearance, supporting their bioactive role in BME. Pretreatment with BME (25\u00a0\u03bcg/mL) significantly (p\u00a0<\u00a00.01) reduced STZ-induced mitochondrial (51.24\u00a0%) and membrane (41.69\u00a0%) damage, as shown by MTT and LDH assays. BME markedly reduced intracellular ROS, protein carbonylation, and lipid peroxidation (p\u00a0<\u00a00.001), while restoring mitochondrial membrane potential, ATP levels, enzymatic antioxidant levels, and glutathione content. Furthermore, BME upregulated brain-derived neurotrophic factor (BDNF) expression and inhibited AGE formation. Collectively, these findings highlight the antioxidant, antiglycation, and neurotrophic actions of BME, underscoring its promise as a multi-targeted phytotherapeutic candidate for DN management.\n\nID: 41080631\nTitle: Nutraceutical benefits and neuro-protective potent of four colored peppers (Capsicum annuum var. grossum).\nAbstract: Four colored peppers (Capsicum annuum var. grossum), orange, purple, yellow and red, are plant foods served as salad or stir-fry for meals in Taiwan and many countries. This study aimed to investigate the multiple nutraceutical properties of aqueous extracts prepared from colored peppers. Vitamin C content and phytochemical profiles of these peppers were analyzed. In vitro effects of anti-oxidative, anti-\u03b1-amylase, anti-\u03b1-glucosidase, anti-lipase and anti-acetylcholinesterase (AchE) of pepper aqueous extracts at 0.25, 0.5 and 1 mg were evaluated. The neuronal protective potent of pepper aqueous extracts at 0.5 and 1 mg in high glucose treated nerve growth factor (NGF)-differentiated PC12 cells were examined. Vitamin C content in these peppers was in the range of 60-96 mg/100 g fresh weight. The content of phenolic acids, flavonoids, anthocyanins and triterpenoids in these peppers was in the range of 860-2185 mg/100 g dry weight. Pepper aqueous extracts at 0.25, 0.5 and 1 mg exhibited concentration-dependent radical scavenging effects, ironchelating effects and reducing power, as well as effectively inhibited \u03b1-amylase, \u03b1-glucosidase, lipase and AchE activities. High glucose increased Bax mRNA expression, decreased mitochondrial membrane potential and Na+-K+ ATPase activity, caused DNA fragmentation and massive Ca2+ release, stimulated oxidative and inflammatory responses, and led to death of NGF-differentiated PC12 cells. Pre-treatments of pepper aqueous extracts at 0.5 and 1 mg reversed these changes, and increased the viability of NGF-differentiated PC12 cells. These novel findings suggest that colored peppers offered many bio-functions, which might benefit the prevention of diabetes associated complications such as diabetic neuropathy.\n\nID: 41030574\nTitle: Exosomal miR-450b-5p Secreted from Exendin-4-Stimulated Endothelial Cells Protects Retinal Ganglion Cells Against Ischemia Reperfusion Injury.\nAbstract: Retinal ischemia-reperfusion (RIR) injury represents a critical pathophysiological mechanism underlying various ocular ischemic diseases, characterized by progressive loss of retinal ganglion cells (RGCs). Exendin-4 (Ex-4), a widely used glucagon-like peptide-1 receptor (GLP-1R) agonist drug in the treatment of type 2 diabetes mellitus, has been reported to protect against ischemia-reperfusion (IR) injury in various vital organs. However, the potential neuroprotective effect of Ex-4 under RIR injury has been poorly understood. Immunofluorescence staining assay, hematoxylin and eosin (HE) staining were conducted to evaluate the neuroprotective role of Ex-4. A co-culture assay of human retinal vascular endothelial cells (HRVECs) and RGCs was established. Extracellular vesicles (EVs) were isolated from the culture supernatant of HRVECs with (E-EVs) or without Ex-4 treatment (O-EVs) under oxygen-glucose deprivation/reoxygenation (OGD/R) condition. Transmission electron microscopy (TEM), Nanoparticle tracking analysis (NTA) and Nano-flow cytometry (NanoFCM) were used to detect the presence and purity of EVs. Cell activity, reactive oxygen species (ROS) level, and cell death rate of RGCs were evaluated. Further global miRNA sequencing was performed on E-EVs or O-EVs to explore potential mechanisms. Our findings revealed that Ex-4\u00a0had a GLP-1R-dependent neuroprotective effect on RGCs. Vascular endothelial cells (VECs) -derived EVs mediate the protective effect of Ex-4 on RGCs under acute RIR injury. We identified miR-450b-5p as a highly enriched miRNA in E-EVs. Treatment with either E-EVs or miR-450b-5p mimics significantly protected RGCs against RIR-induced injury. Mechanistic investigations identified acyl-coenzyme A (CoA) synthetase long-chain family member 4 (ACSL4) as a direct target of miR-450b-5p. Ex-4 exerts its neuroprotective effects under RIR injury by stimulating retinal VECs to secrete miR-450b-5p-enriched EVs, thereby revealing a novel endothelial-mediated neuroprotective pathway in ischemia diseases.\n\nID: 41029921\nTitle: TOX4 Inhibition in Chronic Hyperglycemia: Effects on Glycation Stress, Hepatic Protection, Epigenetic Mechanisms, Signaling Pathways, and Beta Cell Dynamics.\nAbstract: TOX high mobility group box family member 4 (TOX4) has emerged as a critical regulator of Hepatic Glucose Production (HGP), particularly under insulin-resistant conditions seen in Type 2 Diabetes Mellitus (T2DM). Hyperglycemia-induced formation of Advanced Glycation End products (AGEs) exacerbates metabolic dysfunction. While the Akt- FoxO1 axis has been the conventional focus of insulin signaling, recent findings highlight the upregulation of TOX4 in T2DM, obesity, and preclinical models (e.g., db/db mice). The cAMP signaling pathway has been shown to modulate TOX4 expression. This review synthesizes findings from recent in vivo and in vitro studies investigating the role of TOX4 in hepatic metabolism. The study focuses on its regulatory mechanisms, interaction with insulin signalling pathways, and its modulation through pharmacological inhibition. TOX4 inhibition significantly reduces glucose output in hepatocytes and improves glucose tolerance in animal models. While TOX4 ablation fails to reverse metabolic impairments caused by insulin receptor knockout, it nonetheless attenuates hepatic glucose production under insulin- resistant states. Additionally, TOX4 suppression shows hepatoprotective effects and may offer potential neuroprotection in the context of diabetic complications. TOX4 represents a promising therapeutic target for managing T2DM and its comorbidities. Further investigation into selective TOX4 inhibitors and their long-term safety profiles could facilitate the development of adjunct therapies for metabolic disorders involving hepatic and neuronal dysfunction.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment.\n  --- END ACTUAL ABSTRACT FOR 42398881 ---\n\n- ERROR: You cited ID: 41539543 for the quote: \"The current study indicated that betanin was a good candidate for DIR in rats through suppression of the inflammatory cascade\"\n  FACT: Strict Misquote Detected!

Retinal inflammation and angiogenesis contribute largely to the neuronal degeneration in DIR. The current study is aiming to test the effect of oral betanin doses in protection from DIR in rats along with a network pharmacology study to investigate an assumption that betanin may inhibit nuclear factor-\u03ba B (NF-\u03baB). Three rat groups were assigned as vehicle, DIR, and DIR\u00a0+\u00a0Betanin 100\u00a0mg/kg. Molecular docking indicated the possible binding between betanin and NF-\u03baB while the bioinformatic study highlighted a relation between this possible inhibition and suppression of NOD-like receptor pyrin domain-containing protein 3/vascular endothelial growth factor (NLRP3/VEGF) axis. The rat experimental study validated this assumption and indicated a protective effect for betanin on rat retinas as shown by routine hematoxylin and eosin staining (retinal thickness and ganglion cell count) and periodic acid-Schiff staining that was mediated through mitigating expression/protein level for of NF-\u03baB, NLRP3, TNF-\u03b1, IL-6 and VEGF proteins. Immunohistochemistry showed that betanin was able to suppress retinal content of the glial fibrillary acidic protein (GFAP). In conclusion, the current study indicated that betanin was a good candidate for DIR in rats through suppression of the inflammatory cascade and may be suggested for diabetic patients if appropriated clinical studies will be available.\n  --- END ACTUAL ABSTRACT FOR 41539543 ---\n\n- ERROR: You cited ID: 41002420 for the quote: \"Cellular senescence was identified as a critical mechanism underlying RGC dysfunction in diabetes.\"\n  FACT: Quote was found in context but NOT in the specific abstract mapped to ID '41002420'.\n  \n  Below is the complete, true text of ID 41002420 that you MUST read. \n  Find a valid, verbatim, character-perfect sentence inside this exact block to cite instead, or change your claim to align with what this text actually says:\n  \n  --- BEGIN ACTUAL ABSTRACT FOR 41002420 ---\n  ID: 41002420\nTitle: The Form and Function of Retinal Ganglion Cells in Diabetes.\nAbstract: This review examines how diabetes affects the ganglion cells of the retina, including the axons that make up the optic nerve. Links between established changes in the morphology of retinal ganglion cells (RGCs) and vision loss, as well as other functions, such as the pupillary light reflex, are considered. RGC morphology and function are significantly altered in both animal models and humans with diabetes. Diabetes affects all parts of the RGC, including the dendrites, the cell body, the axons making up the nerve fiber layer, and the optic nerve. Subtypes of RGCs appear to be affected differently by diabetes, and the morphology and electrophysiological output are more significantly affected in ON-RGCs than in OFF cells, which may explain part of the mechanism underlying the widely documented diabetes-induced reduction in contrast sensitivity. Furthermore, the morphology of the specialized light-sensitive melanopsin-containing RGCs also appears to be affected by diabetes, which may explain deficits in circadian rhythm and the pupillary light reflex. Potential therapeutic approaches aimed at protecting RGCs in diabetes are also discussed. Overall, strong evidence supports the conclusion that diabetes impacts the form and function of RGCs and their axons within the optic nerve, resulting in deficient regulation of circadian rhythms and the pupillary light reflex, in addition to vision.\n  --- END ACTUAL ABSTRACT FOR 41002420 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function\" (Source: 42456876)\n- \"SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma\" (Source: 42456876)\n- \"SPG302 treatment effectively preserved retinal integrity by reversing these changes.\" (Source: 42456876)\n- \"Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling.\" (Source: 42398881)\n- \"calcium dysregulation is emerging as a unifying pathogenic hub across these conditions.\" (Source: 42352232)\n- \"Acarbose (ACA), an \u03b1-glucosidase inhibitor widely used for diabetes, has recently been recognized for its dual regulatory potential on immune metabolism and aging-associated neurodegeneration.\" (Source: 42069589)\n- \"Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions.\" (Source: 42041557)\n- \"STZ-induced RGC loss was significantly reversed by pelargonidin, with the highest dose restoring RGC density to near-control or higher levels\" (Source: 41963265)\n- \"Several key signaling pathways, including agrin-MuSK-LRP4, Wnt/\u03b2-catenin, and neuregulin/ErbB, govern NMJ maintenance with fiber-type-specific nuances.\" (Source: 41548740)\n- \"GCC (1 mm) may be interesting to explore in predicting visual outcomes after treatment\" (Source: 41101191)\n- \"This is the first demonstration that pharmacological blockade of SRR improves retinopathy and normalizes glucose levels in a type 2 diabetes model.\" (Source: 41237937)\n- \"Our findings suggest that neurodegenerative changes may precede microvascular alterations in non-DR patients\" (Source: 40976316)\n- \"SPG302 treatment effectively preserved synaptic integrity by reversing these changes.\" (Source: 40967391)\n- \"Our findings suggest that NRXNs may play cell-type-specific roles in the inner retina and associate decreased Nrxn3\u03b2 expression in RGCs with inner retinal dysfunction in early DRD.\" (Source: 40833325)\n- \"Silencing HuD and CRYAA enhanced high glucose-induced R-28 cell death, whereas their overexpression alleviated this effect.\" (Source: 40794319)\n- \"Targeted modulation of miRNA-122-5p may offer a novel therapeutic approach to preserve retinal neurons and counteract neurodegeneration in DR.\" (Source: 40759398)\n- \"Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months.\" (Source: 42461929)\n\n\nINSTRUCTION: Study the actual abstracts provided.

SPG302, a pegylated benzothiazole derivative, demonstrates efficacy in promoting glutamatergic synaptogenesis and preserving retinal integrity. This evaluation synthesizes current literature on the impact of diabetes on RGCs, the role of synaptic loss in disease progression, and the therapeutic potential of SPG302 and similar neuroprotective agents.\n\n### [INTRODUCTION & JUSTIFICATION]\nDiabetic retinal neuropathy (DRN) is an early hallmark of diabetic retinopathy that frequently occurs prior to visible microvasculopathy. The pathology involves the loss of RGCs, impaired RGC function, and a significant decrease in inner retinal synaptic markers. Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function. Because loss of glutamatergic synapses contributes to neuronal atrophy, therapeutic interventions targeting synaptic restoration offer a new point for disease mitigation. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma. Studies demonstrate that SPG302 treatment effectively preserved retinal integrity by reversing these changes. \n\nIn both glaucoma and diabetes, RGC vulnerability is driven by metabolic and neurodegenerative processes. Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. In glaucomatous neurodegeneration, synaptic abnormalities are key, and SPG302 treatment effectively preserved synaptic integrity by reversing these changes. Further neuroprotective strategies include the use of norrin to restore PEDF levels, where Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Additionally, mitochondrial homeostasis is critical, as evidenced by studies showing sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   DRN often presents as a neurodegenerative disease manifesting before clinical microvascular damage is visible.\n*   SPG302 promotes glutamatergic synaptogenesis, offering a potential mechanism to restore synaptic connections that are lost early in the disease process.\n*   Mitochondrial transplantation and mitophagy regulation represent emerging frontiers in preserving RGC viability.\n*   Norrin, a protein secreted by M\u00fcller cells, is crucial for Wnt signaling and retinal capillary formation, and its downregulation is a key pathological event in diabetes.\n*   Neuroprotective effects of therapeutics such as fenofibrate, pelargonidin, and UAB126-MP occur via diverse signaling pathways (e.g., RXR agonism) distinct from conventional pressure-lowering.\n*   The integrity of the neurovascular unit is fundamentally tied to synaptic communication, which remains dysregulated following RGC injury.\n*   Emerging gene therapies, such as WFS1 delivery, show promise for genetic-based optic neuropathies.\n*   Advanced imaging and machine learning (e.g., 2.5D CFF module) are improving the precision of diagnostic markers like the Ganglion Cell Complex (GCC).\n*   Dietary and natural compounds, including eucalyptol and L-serine, show evidence for mitigating metabolic features of diabetic neuropathy.\n*   The relationship between systemic metabolic health and retinal neurodegeneration suggests that retinal assessment could serve as a systemic prognostic tool.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

        "29452885": "ID: 29452885\nTitle: Somatolactogens and diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR) is one of the most common of all diabetic complications. The number of people with DR in the United States is expected to increase to 16 million by 2050. DR is the leading cause of blindness among working-age adults in many different countries, including the United States. In later DR stages, neovascularization is associated with extensive retinal capillary non-perfusion and vitreo-proliferation leading to retinal detachment. This neovascularization is orchestrated by an imbalance of growth factors in the retina from which somatolactogens (pituitary growth hormone, GH-N; placental growth hormone, GH-V; prolactin, PRL; and placental lactogen, PL, also referred as chorionic somatomammotropin, CSH), may play an important role. Somatolactogens are a group of hormones that share many structural and functional features. They are important for physiological changes in pregnancy, for adequate development of the fetus, and in the case of GH-N, for promoting growth after birth. GH-N is synthesized by the anterior pituitary, GH-V and PL are secreted by the placenta, whereas, PRL is synthesized by the anterior pituitary and uterine decidua. However, in recent years the expression of GH-N and PRL and their receptors have been detected in other tissues including the retina, acting as neuroprotective and pro-angiogenic agents. The relationship of GH-N and diabetic retinopathy (DR) was established many years ago when it was observed that its deficiency was related to regression of DR while an increase in serum levels of GH-N, GH-V, and PL promoted DR. While more studies are needed to define the potential implications of GH-V and PL in DR pathogenesis, it has been demonstrated that GH-N and PRL participate in DR by enhancing neovascularization. Some PRL isoforms, however, have shown an anti-angiogenic activity rather than pro-angiogenesis and appears to be PRL's main role in the regulation of retinal vasculature. Somatolactogens are a group of hormones with a significant role in neuroprotection and angiogenesis regulation in the eye. Understanding the mechanisms of angiogenesis regulation by somatolactogens will potentially lead to the development of new drugs for DR.",
        "29565290": "ID: 29565290\nTitle: Role of Inflammation in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy is a common complication of diabetes and remains the leading cause of blindness among the working-age population. For decades, diabetic retinopathy was considered only a microvascular complication, but the retinal microvasculature is intimately associated with and governed by neurons and glia, which are affected even prior to clinically detectable vascular lesions. While progress has been made to improve the vascular alterations, there is still no treatment to counteract the early neuro-glial perturbations in diabetic retinopathy. Diabetes is a complex metabolic disorder, characterized by chronic hyperglycemia along with dyslipidemia, hypoinsulinemia and hypertension. Increasing evidence points to inflammation as one key player in diabetes-associated retinal perturbations, however, the exact underlying molecular mechanisms are not yet fully understood. Interlinked molecular pathways, such as oxidative stress, formation of advanced glycation end-products and increased expression of vascular endothelial growth factor have received a lot of attention as they all contribute to the inflammatory response. In the current review, we focus on the involvement of inflammation in the pathophysiology of diabetic retinopathy with special emphasis on the functional relationships between glial cells and neurons. Finally, we summarize recent advances using novel targets to inhibit inflammation in diabetic retinopathy.",

Recent work has revealed that neurodegeneration occurs earlier than vascular insult and that distal optic nerve damage precedes retinal degeneration and vascular insult. Since we have shown that optic nerve degeneration is reduced after optic nerve crush in Galectin-3 knockout (Gal-3 -/-) mice, we decided to investigate whether Gal-3 -/- could relieve inflammation and preserve both neurons and the structure of the retina and optic nerve following 8\u202fweeks of diabetes. Diabetes was induced in 2-month-old male C57/bl6 WT or Gal-3 -/- mice by a single injection of streptozotocin (160\u202fmg/kg). Histomorphometric retinal analyses showed no gross difference, except for a reduced number of retinal ganglion cells in WT diabetic mice, correlated to increased apoptosis. In the optic nerve, Gal-3 -/- mice showed reduced neuroinflammation, suggested by the smaller number of Iba1+ cells, particularly the amoeboid profiles in the distal end. Furthermore, iNOS staining was reduced in the optic nerves of Gal-3 -/- mice, as well as GFAP in the distal segment of the optic nerve. Finally, optic nerve histomorphometric analyses revealed that the number of myelinated fibers was higher in the Gal-3 -/- mice and myelin was more rectilinear compared to WT diabetic mice. Therefore, the present study provided evidence that Gal-3 is a central target that stimulates neuroinflammation and impairs neurological outcomes in visual complications of diabetes. Our findings provide support for the clinical use of Gal-3 inhibitors against diabetic visual complications in the near future.",
        "30190527": "ID: 30190527\nTitle: Different contributions of autophagy to retinal ganglion cell death in the diabetic and glaucomatous retinas.\nAbstract: Diabetes mellitus and glaucoma are the two major causes of selective retinal ganglion cell (RGC) death. To determine the relationship between autophagy and RGC death, we compared autophagy and the related molecular pathways in diabetic and glaucomatous retinas and examined their effect on RGC survival. Biochemical analysis of microtubule-associated protein light chain 3 (LC3)-II and beclin-1 were observed. To determine the pathways involved in autophagy induction, adenosine monophosphate-activated protein kinase (AMPK) and the mechanistic target of rapamycin (mTOR) were also explored. Beclin-1 and the LC3B-II to LC3B-I ratio significantly elevated at 4 and 8 weeks after glaucoma induction; however, only a slight increase was apparent in the diabetic retina. Significant upregulation of phosphorylated AMPK and downregulation of phosphorylated mTOR was evident in the diabetic retina. After autophagy was inhibited with 3-methyladenine (3-MA), apoptosis of RGCs was significantly increased in the diabetic retinas. However, 3-MA inhibition of autophagy decreased the apoptosis of RGCs in glaucomatous retinas. Therefore, our results suggest that RGC death is differentially regulated by autophagy and that the pathways involved differ depending on the triggering injury.",

The aims of this study were: (1) to determine whether high fat diet/low dose streptozotocin-diabetes, a rat model for type 2 diabetes, related PDN was also associated with this synaptic plasticity, (2) to reveal the range of this synaptic plasticity change occurred (in the whole length of spinal dorsal horn or only in the L5 lumbar segment of spinal dorsal horn) and (3) to discover whether treatment with metformin had effect on this synaptic plasticity. Male adult Sprague-Dawley rats were randomly allocated into the control group (n\u2009=\u20097), the PDN group (n\u2009=\u20096) and the PDN treated with metformin (PDN\u2009+\u2009M) group (n\u2009=\u20097), respectively. 28\u00a0days after medication, synaptic and neuronal numbers in the whole length of spinal dorsal horn or in 1\u00a0mm length of the L5 segment of spinal dorsal horn were estimated by the optical disector (a stereological technique). Compared to the control group and the PDN\u2009+\u2009M group, number of synapses in the L5 segment of spinal dorsal horn increased significantly in the PDN group (P\u2009<\u20090.05). There was no significant change between the control group and the PDN\u2009+\u2009M group in terms of the parameters in the L5 segment of the spinal dorsal horn (P\u2009>\u20090.05). Parameters of the whole length of spinal dorsal horn showed no significant changes (P\u2009>\u20090.05). Our results suggest that high fat diet/low dose streptozotocin diabetes related PDN is also associated with a numerical increase of synapses in the L5 segment of spinal dorsal horn but not in the whole length of spinal dorsal horn. Furthermore, the analgesic effect of metformin against PDN is related to its inhibition of numerical increase of synaptic number in the rat spinal dorsal horn.",
        "30690195": "ID: 30690195\nTitle: Connexin43 hemichannels: A potential drug target for the treatment of diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR) is a chronic vascular disease of the retina that causes vision loss in patients with type 1 and type 2 diabetes, and is associated with vascular dysfunction and occlusion, retinal oedema, haemorrhage and inadequate growth of new blood vessels. Current DR therapies primarily target downstream, later-stage vascular defects with a significant proportion of diabetic macular oedema patients being non-responders. Moreover, other evidence suggests that prolonged use of therapies targeting vascular endothelial growth factor (VEGF) might be associated with increased onset of geographic atrophy and retinal ganglion cell death. It is therefore highly desirable to prevent the onset of DR or arrest its progression at a stage preceding the appearance of more-advanced pathology by targeting upstream disease mechanisms. Connexin43 hemichannels play a part in the pathogenesis of chronic inflammatory diseases, including inflammasome pathway activation; and hemichannel block has been shown to alleviate vascular leak and inflammation. This review discusses the inflammatory changes occurring in DR as well as current therapies and their limitations. It then focuses on the role of connexin43 in DR, providing evidence for the utility of connexin43 hemichannel blockers as novel therapeutics for DR treatment.",
        "30806815": "ID: 30806815\nTitle: Retinal Neurodegeneration as an Early Manifestation of Diabetic Eye Disease and Potential Neuroprotective Therapies.\nAbstract: Diabetic retinopathy (DR) is a major cause of visual impairment and blindness throughout the world. Microvascular changes have long been regarded central to disease pathogenesis. In recent years, however, retinal neurodegeneration is increasingly being hypothesized to occur prior to the vascular changes classically associated with DR and contribute to disease pathogenesis. There is growing structural and functional evidence from human and animal studies that suggests retinal neurodegeneration to be an early component of DR. Identification of new therapeutic targets is an ongoing area of research with several different molecules undergoing testing in animal models for their neuroprotective properties and for possible use in humans. Retinal neurodegeneration may play a central role in DR pathogenesis. As new therapies are developed, it will be important to develop criteria for clinically defining retinal neurodegeneration. A standardization of the methods for monitoring neurodegeneration along with more sensitive means of detecting preclinical damage is also needed.",
        "31061088": "ID: 31061088\nTitle: Limiting Neuronal Nogo Receptor 1 Signaling during Experimental Autoimmune Encephalomyelitis Preserves Axonal Transport and Abrogates Inflammatory Demyelination.\nAbstract: We previously identified that ngr1 allele deletion limits the severity of experimental autoimmune encephalomyelitis (EAE) by preserving axonal integrity. However, whether this favorable outcome observed in EAE is a consequence of an abrogated neuronal-specific pathophysiological mechanism, is yet to be defined. Here we show that, Cre-loxP-mediated neuron-specific deletion of ngr1 preserved axonal integrity, whereas its re-expression in ngr1-/- female mice potentiated EAE-axonopathy. As a corollary, myelin integrity was preserved under Cre deletion in ngr1flx/flx , retinal ganglion cell axons whereas, significant demyelination occurred in the ngr1-/- optic nerves following the re-introduction of NgR1. Moreover, Cre-loxP-mediated axon-specific deletion of ngr1 in ngr1flx/flx mice also demonstrated efficient anterograde transport of fluorescently-labeled ChTx\u03b2 in the optic nerves of EAE-induced mice. However, the anterograde transport of ChTx\u03b2 displayed accumulation in optic nerve degenerative axons of EAE-induced ngr1-/- mice, when NgR1 was reintroduced but was shown to be transported efficiently in the contralateral non- recombinant adeno-associated virus serotype 2-transduced optic nerves of these mutant mice. We further identified that the interaction between the axonal motor protein, Kinesin-1 and collapsin response mediator protein 2 (CRMP2) was unchanged upon Cre deletion of ngr1 Whereas, this Kinesin-1/CRMP2 association was reduced when NgR1 was re-expressed in the ngr1-/- optic nerves. Our data suggest that NgR1 governs axonal degeneration in the context of inflammatory-mediated demyelination through the phosphorylation of CRMP2 by stalling axonal vesicular transport. Moreover, axon-specific deletion of ngr1 preserves axonal transport mechanisms, blunting the induction of inflammatory demyelination and limiting the severity of EAE.SIGNIFICANCE STATEMENT Multiple sclerosis (MS) is commonly induced by aberrant immune-mediated destruction of the protective sheath of nerve fibers (known as myelin). However, it has been shown that MS lesions do not only consist of this disease pattern, exhibiting heterogeneity with continual destruction of axons. Here we investigate how neuronal NgR1 can drive inflammatory-mediated axonal degeneration and demyelination within the optic nerve by analyzing its downstream signaling events that govern axonal vesicular transport. We identify that abrogating the NgR1/pCRMP2 signaling cascade can maintain Kinesin-1-dependent anterograde axonal transport to limit inflammatory-mediated axonopathy and demyelination. The ability to differentiate between primary and secondary mechanisms of axonal degeneration may uncover therapeutic strategies to limit axonal damage and progressive MS.",
        "31207342": "ID: 31207342\nTitle: Spermine oxidase: A promising therapeutic target for neurodegeneration in diabetic retinopathy.\nAbstract: Diabetic Retinopathy (DR), is a significant public health issue and the leading cause of blindness in working-aged adults worldwide. The vision loss associated with DR affects patients' quality of life and has negative social and psychological effects. In the past, diabetic retinopathy was considered as a vascular disease; however, it is now recognized to be a neuro-vascular disease of the retina. Current therapies for DR, such as laser photocoagulation and anti-VEGF therapy, treat advanced stages of the disease, particularly the vasculopathy and have adverse side effects. Unavailability of effective treatments to prevent the incidence or progression of DR is a major clinical problem. There is a great need for therapeutic interventions capable of preventing retinal damage in DR patients. A growing body of evidence shows that neurodegeneration is an early event in DR pathogenesis. Therefore, studies of the underlying mechanisms that lead to neurodegeneration are essential for identifying new therapeutic targets in the early stages of DR. Deregulation of the polyamine metabolism is implicated in various neurodegenerative diseases, cancer, renal failure, and diabetes. Spermine Oxidase (SMOX) is a highly inducible enzyme, and its dysregulation can alter polyamine homeostasis. The oxidative products of polyamine metabolism are capable of inducing cell damage and death. The current review provides insight into the SMOX-regulated molecular mechanisms of cellular damage and dysfunction, and its potential as a therapeutic target for diabetic retinopathy. Structural and functional changes in the diabetic retina and the mechanisms leading to neuronal damage (excitotoxicity, loss of neurotrophic factors, oxidative stress, mitochondrial dysfunction etc.) are also summarized in this review. Furthermore, existing therapies and new approaches to neuroprotection are discussed.",
        "31481518": "ID: 31481518\nTitle: Streptozotocin-Induced Diabetic Neuropathic Pain Is Associated with Potentiated Calcium-Permeable AMPA Receptor Activity in the Spinal Cord.\nAbstract: Neuronal hyperactivity in the spinal dorsal horn can amplify nociceptive input in diabetic neuropathic pain. The glutamate N-methyl-d-aspartate and \u03b1-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptors (NMDA receptors and AMPA receptors, respectively) are involved in spinal nociceptive transmission. It is unclear, however, whether painful diabetic neuropathy is associated with changes in the activity of synaptic NMDA receptors and AMPA receptors in spinal dorsal horn neurons. AMPA receptors lacking GluA2 are Ca2+-permeable (CP-AMPA receptors), and their currents display characteristic inward rectification. In this study, we showed that evoked excitatory postsynaptic currents (EPSCs), induced by streptozotocin, exhibited inward rectification in spinal dorsal neurons in diabetic rats. Presynaptic and postsynaptic NMDA receptor activity in the spinal dorsal horn was similar in diabetic and control rats. In the dorsal spinal cord, the membrane GluA2 protein level was significantly lower in diabetic than in control rats, whereas the cytosolic GluA2 level was greater in diabetic than in control rats. In contrast, the GluA1 subunit levels in the plasma membrane and cytosol did not differ between the two groups. Blocking CP-AMPA receptors significantly reduced the amplitude of EPSCs of dorsal horn neurons in diabetic but not in control rats. Furthermore, blocking spinal CP-AMPA receptors reduced pain hypersensitivity in diabetic rats but had no effect on nociception in control rats. Our study suggests that diabetic neuropathy augments CP-AMPA receptor activity in the spinal dorsal horn by causing intracellular retention of GluA2 and impairing GluA2 membrane trafficking. Increased prevalence of spinal CP-AMPA receptors sustains diabetic neuropathic pain. SIGNIFICANCE STATEMENT: This study demonstrates that the prevalence of synaptic calcium-permeable AMPA receptors is increased in the spinal dorsal horn, which mediates pain hypersensitivity in diabetic neuropathy. Thus, calcium-permeable AMPA receptors play an important role in glutamatergic synaptic plasticity in the spinal cord in painful diabetic neuropathy. This new knowledge improves our understanding of the mechanisms involved in central sensitization associated with diabetic neuropathic pain and suggests that calcium-permeable AMPA receptors are an alternative therapeutic target for treating this chronic pain condition.",

The adaptor protein APPL1 is critical in mediating the insulin sensitizing and insulin signaling. In neurons, APPL1 reportedly affects synaptic plasticity, while its role in the pathogenesis of painful diabetic neuropathy is masked. Our Western blotting revealed significantly decreased APPL1 expression in the dorsal horn in streptozocin-induced rats versus the control rats, coupled with concomitant mechanical and thermal hyperalgesia. Afterward, the determination of exact localization of APPL1 in spinal cord by immunofluorescent staining assay revealed highly expressed APPL1 in the lamina of spinal dorsal horn in control rats, with the overexpression in neurons, microglia, and underexpression in astrocytes. The APPL1 expression in laminae I and II was significantly downregulated in painful diabetic neuropathy rats. In addition, APPL1 deficiency or overexpression contributed to the increase or decrease of Map and Bassoon, respectively. The localization and immunoactivity of APPL1 and mammalian target of rapamycin (mTOR) were determined in spinal dorsal horn in painful diabetic neuropathy rats and control rats by immunohistochemistry, suggesting pronounced decrease in APPL1 expression in the superficial layer of the spinal cord in painful diabetic neuropathy rats, with p-mTOR expression markedly augmented. APPL1 knockdown by infection with lentiviral vector facilitated the activation of mTOR and abrogated mechanical withdrawal threshold values in painful diabetic neuropathy rats. Genetically overexpressed APPL1 significantly eliminated the activation of mTOR and resulted in the augmented mechanical withdrawal threshold values and thermal withdrawal latency values. Furthermore, the APPL1 levels affect phosphorylation of adenosine monophosphate-activated protein kinase (AMPK), and Akt, as well as the small GTPase, Rab5 expression in painful diabetic neuropathy rats. Our results uncovered a novel mechanism by which APPL1 deficiency facilitates the mTOR activation and thus exacerbates the hyperalgesia in streptozocin-induced diabetic rats, presumably via the regulation of Rab5/Akt and AMPK signaling pathway.",

The repressive effect of PACAP1-38 on the apoptotic machinery has been an area of active research conferring a significant neuroprotective potential onto this peptide. A remarkable number of studies suggest its importance in the etiology of neurodegenerative disorders, particularly in relation to retinal metabolic disorders. In our review, we provide short descriptions of various pathological conditions (diabetic retinopathy, excitotoxic retinal injury and ischemic retinal lesion) in which the remedial effect of PACAP has been well demonstrated in various animal models. Of all the pathological conditions, diabetic retinopathy seems to be the most intriguing as it develops in 75% of patients with type 1 and 50% of patients with type 2 diabetes, with concomitant progression to legal blindness in about 5%. Several animal models have been developed in recent years to study retinal degenerations and out of these glaucoma and age-related retina degeneration models bear human recapitulations. PACAP neuroprotection is thought to operate through enhanced cAMP production upon binding to PAC1-R. However, the underlying signaling network that leads to neuroprotection is not fully understood. We observed that (i) PACAP is not equally efficient in the above conditions; (ii) in some cases more than one signaling pathways are activated; (iii) the coupling of PAC1-R and signaling is stage dependent; and (iv) PAC1-R is not the only receptor that must be considered to interpret the effects in our experiments. These observations point to a complex signaling mechanism, that involves alternative routes besides the classical cAMP/protein kinase A pathway to evoke the outstanding neuroprotective action. Consequently, the possible contribution of the other two main receptors (VPAC1-R and VPAC2-R) will also be discussed. Finally, the potential medical use of PACAP in some retinal and ocular disorders will also be reviewed. By taking advantage of, low-cost synthesis technologies today, PACAP may serve as an alternative to the expensive treatment modelities currently available in ocular or retinal conditions.",

We investigated the role of the neuroprotective kynurenic acid (KYNA) in RGC death against retinal ischemia/reperfusion (I/R) injury. We injected KYNA intravenously or intravitreally to mice. We generated a knockout mouse strain of kynurenine 3-monooxygenase (KMO), an enzyme in the kynurenine pathway that produces neurotoxic 3-hydroxykynurenine. To test the effect of mild hyperglycemia on RGC protection, we used streptozotocin (STZ) induced diabetic mice. Retinal I/R injury was induced by increasing intraocular pressure for 60 min followed by reperfusion and RGC numbers were counted in the retinal flat mounts. Intravenous or intravitreal administration of KYNA protected RGCs against I/R injury. The I/R injury caused a greater loss of RGCs in wild type than in KMO knockout mice. KMO knockout mice had mildly higher levels of fasting blood glucose than wild type mice. Diabetic mice showed significantly lower loss of RGCs when compared with non-diabetic mice subjected to I/R injury. Together, our study suggests that the absence of KMO protects RGCs against I/R injury, through mechanisms that likely involve higher levels of KYNA and glucose.",

Mice were randomized into four groups: normal, control, carbamazepine (25-mg/kg) and carbamazepine (50-mg/kg). Nine weeks after induction of diabetes, symptoms of neuropathy were confirmed and carbamazepine (or vehicle) was given every other day for five weeks. After completing the treatment period, mice were sacrificed and the pathologic features in the spinal cord and the sciatic nerves were determined. The spinal cords were evaluated for synaptic plasticity (growth associated protein-43, GAP43), microglia cell expression (by CD11b) and astrocyte expression (glial fibrillary acidic protein, GFAP). Further, sciatic nerve expression of Nav1.5 was measured. Results revealed that carbamazepine 50\u00a0mg/kg prolonged the withdrawal threshold of von-Frey filaments and increased the hot plate jumping time. Carbamazepine improved the histopathologic pictures of the sciatic nerves and spinal cords. Spinal cord of carbamazepine-treated groups had enhanced expression of GAP43 but lower content of CD11b and GFAP. Furthermore, specimens from the sciatic nerve indicated low expression of Nav1.5. In conclusion, this work provided evidence, for the first time, that the preventive effect of carbamazepine against diabetic neuropathy involves correction of spinal neuronal plasticity and glia cell expression.",

After 20 years of diabetes, almost all patients suffering from type I diabetes mellitus and about 60% of type II diabetics have DR. Several studies have tried to identify drugs and therapies to treat DR though little attention has been given to flavonoids, one type of polyphenols, which can be found in high levels mainly in fruits and vegetables, but also in other foods such as grains, cocoa, green tea or even in red wine. Flavonoids have anti-inflammatory, antioxidant and antiviral effects. Since it is known that diabetes induces oxidative stress and inflammation in the retina leading to neuronal death in the early stages of the disease, the use of these compounds can prove to be beneficial in the prevention or treatment of DR. In this review, we summarize the molecular and cellular effects of flavonoids in the diabetic retina.",

However, its underlying pathogenesis and effective treatment strategies remain unclear. In the present study, we investigated the effect of Lipin1, a phosphatidic acid phosphatase enzyme, on the pathogenesis of diabetic encephalopathy. We found that in vitro, Lipin1 exerts protective effects on high glucose-induced reductions of PC12 cell viability, while in vivo, Lipin1 is downregulated within the CA1 hippocampal region in a type I diabetes rat model. Increased levels of Lipin1 within the CA1 region are accompanied with protective effects including amelioration of dendritic spine and synaptic deficiencies, phosphorylation of the synaptic plasticity-related proteins, LIM kinase 1 (p-limk1) and cofilin, as well as increases in the synthesis of diacylglycerol (DAG), and the expression of phosphorylated protein kinase D (p-PKD). These effects are associated with the rescue of cognitive disorders as shown in this rat model of diabetes. In contrast, knockdown of Lipin1 within the CA1 region enhanced neuronal abnormalities and the genesis of cognitive impairment in rats. These results suggest that Lipin1 may exert neuroprotective effects involving the PKD/Limk/Cofilin signaling pathway and may serve as a potential therapeutic target for diabetic encephalopathy.",

The main component of XST is Panax notoginseng saponins (PNS), which is the main extract of the Chinese herbal medicine Panax notoginseng. In this study, we investigated whether XST provided long-term neuroprotection by inhibiting neurite outgrowth inhibitor-A (Nogo-A) and the ROCKII pathway in experimental rats after middle cerebral artery occlusion (MCAO) and in SH-SY5Y cells exposed to oxygen-glucose deprivation/reperfusion (OGD/R). Rats with permanent MCAO were administered XST, Y27632, XST plus Y27632, and nimodipine for 14 and 28 days. Successful MCAO onset was confirmed by 2,3,5-triphenyl tetrazolium chloride (TTC) staining. Neurological deficit score (NDS) was used to assess neurological impairment. Hematoxylin-eosin (HE) staining and immunohistochemical (IHC) analysis of synaptophysin (SYN) and postsynaptic density protein-95 (PSD-95) were performed to evaluate cerebral ischemic injury and the neuroprotective capability of XST. Nogo-A levels and the ROCKII pathway were detected by IHC analysis, western blotting, and quantitative real-time polymerase chain reaction (qRT-PCR) to explore the protective mechanism of XST. OGD/R model was established in SH-SY5Y cells. Cell counting kit 8 (CCK8) was applied to detect the optimum OGD time and XST concentration. The expression levels Nogo-A and ROCKII pathway were determined using western blotting. Our results showed that XST reduced neurological dysfunction and pathological damage, promoted weight gain and synaptic regeneration, reduced Nogo-A mRNA and protein levels, and inhibited the ROCKII pathway in MCAO rats. CCK8 assay displayed that the optimal OGD time and optimal XST concentration were 7\u00a0h and 20\u00a0\u03bcg/mL respectively in SH-SY5Y cells. XST could evidently inhibit OGD/R-induced Nogo-A protein expression and ROCKII pathway activation in SH-SY5Y cells. The present study suggested that XST exerted long-term neuroprotective effects that assisted in stroke recovery, possibly through inhibition of the ROCKII pathway.",

CARV is able to cross the blood-brain barrier (BBB) and has demonstrated protective potential against neurodegenerative diseases by several mechanisms, including antioxidant, anti-inflammatory, anticholinesterase, and antiapoptotic effects. However, it is not known whether CARV is able to modulate axonal and synaptic plasticity, crucial events in cognition, memory, and learning. Abnormalities in axonal and synaptic plasticity, low levels of neurotrophins, and bioenergetic failure have been associated with the pathogenesis of neurodegenerative diseases, including Parkinson's (PD) and Alzheimer's diseases (ADs). Small lipophilic molecules with neurotrophic activity might be able to restore the axonal and synaptic networks that are lost in neurodegenerative processes. Therefore, this study investigated the neurotrophic potential of CARV in PC12 cell-based neuronal model. Carvacrol induced neurite outgrowth by activating the NGF high-affinity trkA receptor and the downstream PI3K-AKT and MAPK-ERK pathways, without depending on NGF. In addition, CARV increased the expression of proteins involved in neuronal plasticity (\u03b2-tubulin III, F-actin, 200-kDa neurofilament, GAP-43 and synapsin-I) and improved bioenergetics (AMPK\u03b1, p-AMPK\u03b1, and ATP).

However, the molecular mechanism underlying this distinct synaptic plasticity remains enigmatic. Here, we show that nerve injury potentiates postsynaptic, but not presynaptic, CP-AMPARs in the spinal dorsal horn via \u03b12\u03b4-1. Overexpressing \u03b12\u03b4-1, previously regarded as a Ca2+ channel subunit, augments CP-AMPAR levels at the cell surface and synapse. Mechanistically, \u03b12\u03b4-1 physically interacts with both GluA1 and GluA2 via its C terminus, inhibits the GluA1/GluA2 heteromeric assembly, and increases GluA2 retention in the endoplasmic reticulum. Consequently, \u03b12\u03b4-1 diminishes the availability and synaptic expression of GluA1/GluA2 heterotetramers in the spinal cord in neuropathic pain. Inhibiting \u03b12\u03b4-1 with gabapentin or disrupting the \u03b12\u03b4-1-AMPAR complex fully restores the intracellular assembly and synaptic dominance of heteromeric GluA1/GluA2 receptors.

With obesity at epidemic proportions, diabetes-related ocular problems are exponentially increasing in the developed world. Oxidative stress due to hyperglycemic states and its associated inflammation is one of the pathological mechanisms which leads to depletion of endogenous antioxidants in retina in a diabetic patient. This contributes to a cascade of events that finally leads to retinal neurodegeneration and irreversible vision loss. The xanthophylls lutein and zeaxanthin are known to promote retinal health, improve visual function in retinal diseases such as age-related macular degeneration that has oxidative damage central in its etiopathogenesis. Thus, it can be hypothesized that dietary supplements with xanthophylls that are potent antioxidants may regenerate the compromised antioxidant capacity as a consequence of the diabetic state, therefore ultimately promoting retinal health and visual improvement. We performed a comprehensive literature review of the National Library of Medicine and Web of Science databases, resulting in 341 publications meeting search criteria, of which, 18 were found eligible for inclusion in this review. Lutein and zeaxanthin demonstrated significant protection against capillary cell degeneration and hyperglycemia-induced changes in retinal vasculature. Observational studies indicate that depletion of xanthophyll carotenoids in the macula may represent a novel feature of DR, specifically in patients with type 2 or poorly managed type 1 diabetes. Meanwhile, early interventional trials with dietary carotenoid supplementation show promise in improving their levels in serum and macular pigments concomitant with benefits in visual performance. These findings provide a strong molecular basis and a line of evidence that suggests carotenoid vitamin therapy may offer enhanced neuroprotective effects with therapeutic potential to function as an adjunct nutraceutical strategy for management of diabetic retinopathy.",

Thirty-four wild-type mice (129S1/SvlmJ) were anesthetized and imaged between postnatal (P) day 7 and P21. OCT instrumentation was developed to optimize signal intensity and image quality. Semi-automatic segmentation tools were developed to quantify the retinal thickness of the nerve fiber layer (NFL), inner plexiform layer (IPL), inner nuclear layer (INL), and the outer retinal layers (ORL), in addition to the total retina. The retinal maturation was characterized by comparing layer thicknesses between consecutive time points. From P7 to P10, the IPL increased significantly, consistent with retinal synaptogenesis. From P10 to P12, the IPL and ORL also increased, which is coherent with synaptic connectivity and photoreceptor maturation. In contrast, during these periods, the INL decreased significantly, consistent with cellular densification and selective apoptotic \"pruning\" of the tissue during nuclear migration. Thereafter from P12 to P21, the INL continued to thin (significantly from P17 to P21) whereas the other layers remained unchanged. No time-dependent changes were observed in the NFL. Overall, changes in the total retina were attributed to those in the IPL, INL, and ORL. Regions of the retina adjacent to the optic nerve head were thinner than distal regions during maturation. Changes in retinal layer thickness are consistent with retinal developmental mechanisms. Accordingly, this report opens new horizons in using our system in the mouse to characterize longitudinally developmental digressions in models of human diseases.",

Secondary damage presents the greatest challenge for medical staff; however, there are currently few effective therapeutic targets for secondary damage. Homer proteins are postsynaptic scaffolding proteins that have been implicated in ischemic and traumatic insults to the central nervous system. Homer signaling can exert either positive or negative effects during such insults, depending on the specific subtype of Homer protein. Homer 1b/c couples with other proteins to form postsynaptic densities, which form the basis of synaptic transmission, while Homer1a expression can be induced by harmful external factors. Homer 1c is used as a unique biomarker to reveal alterations in synaptic connectivity before and during the early stages of apoptosis in retinal ganglion cells, mediated or affected by extracellular or intracellular signaling or cytoskeletal processes. This review summarizes the structural features, related signaling pathways, and diverse roles of Homer proteins in physiological and pathological processes. Upregulating Homer1a or downregulating Homer1b/c may play a neuroprotective role in secondary brain injuries. Homer also plays an important role in the formation of photoreceptor synapses. These findings confirm the neuroprotective effects of Homer, and support the future design of therapeutic drug targets or gene therapies for ischemic and traumatic brain injuries and retinal disorders based on Homer proteins.",

It is the leading irreversible cause of vision loss worldwide, and vision loss results from damage and dysfunction of the retinal output neurons known as retinal ganglion cells (RGCs). Recent Advances: Elevated IOP and optic nerve injury triggers pruning of RGC dendrites, altered morphology of excitatory inputs from presynaptic bipolar cells, and disrupted RGC synaptic function. Less is known about RGC outputs, although evidence to date indicates that glaucoma is associated with altered mitochondrial and synaptic structure and function in RGC-projection targets in the brain. These early functional changes likely contribute to vision loss and might be a window into early diagnosis and treatment. Critical Issues: Glaucoma affects different RGC populations to varying extents and along distinct time courses. The influence of glaucoma on RGC synaptic function as well as the mechanisms underlying these effects remain to be determined. Since RGCs are an especially energetically demanding population of neurons, altered intracellular axon transport of mitochondria and mitochondrial function might contribute to RGC synaptic dysfunction in the retina and brain as well as RGC vulnerability in glaucoma. Future Directions: The mechanisms underlying differential RGC vulnerability remain to be determined. Moreover, the timing and mechanisms of RGCs synaptic dysfunction and degeneration will provide valuable insight into the disease process in glaucoma. Future work will be able to capitalize on these findings to better design diagnostic and therapeutic approaches to detect disease and prevent vision loss. Antioxid. Redox Signal. 37, 842-861.",

Diabetic retinopathy(DR), the most common complication of diabetes, is also the main cause of impaired vision and blindness in the middle-aged and the elderly. The latest research shows that ginsenoside Rg_1 can protect patients against DR, but the protection and the mechanism are rarely studied. This study mainly explored the protective effect of ginsenoside Rg_1 against DR in type 2 diabetic mice and the mechanism. High fat diet(HFD) and streptozotocin(STZ) were used to induce type 2 diabetes in mice, and hematoxylin-eosin(HE) staining was employed to observe pathological changes in the retina of mice. The immunohistochemistry was applied to study the localization and expression of nucleotide-binding oligomerization domain-like receptors 3(NLRP3) and vascular endothelial growth factor(VEGF) in retina, and Western blot was used to detect the expression of nuclear factor-kappa B(NF-\u03baB), p-NF-\u03baB, NLRP3, caspase-1, interleukin-1\u03b2(IL-1\u03b2), transient receptor potential channel protein 6(TRPC6), nuclear factor of activated T-cell 2(NFAT2), and VEGF in retina. The results showed that ginsenoside Rg_1 significantly alleviated the pathological injury of retina in type 2 diabetic mice. Immunohistochemistry results demonstrated that ginsenoside Rg_1 significantly decreased the expression of NLRP3 and VEGF in retinal ganglion cells, middle plexiform layer, and outer plexiform layer in type 2 diabetic mice. According to the Western blot results, ginsenoside Rg_1 significantly lowered the expression of p-NF-\u03baB, NLRP3, caspase-1, IL-1\u03b2, TRPC6, NFAT2, and VEGF in retina of type 2 diabetic mice.

Neurotrophins, like NGF (nerve growth factor), are endogenous proteins that induce neuritogenesis and modulate axonal growth, branching, and synapsis; however, their therapeutic application is limited mainly by low stability, short half-life, and inability to cross the blood-brain barrier (BBB). Small neurotrophic molecules that have suitable pharmacokinetics and are able to cross the BBB are potential candidates for neuroprotection. Baccharin is a bioactive small molecule isolated from Brazilian green propolis. In the present study, we investigated the neurotrophic and neuroprotective potential of baccharin in the PC12 cell neuronal model. We used pharmacological inhibitors (K252a, LY294002, and U0126), and ELISA (phospho-trkA, phospho-Akt, and phospho-MEK) to investigate the involvement of trkA receptor, PI3k/Akt pathway, and MAPK/Erk pathway, respectively. Additionally, we evaluated the expression of axonal (GAP-43) and synaptic (synapsin I) proteins by western blot. The results showed that baccharin induces neuritogenesis in NGF-deprived PC12 cells, through activation of trkA receptor and the downstream signaling cascades (PI3K/Akt and MAPK/ERK), which is the same neurotrophic pathway activated by NGF in PC12 cells and neurons. Baccharin also induced the expression of GAP-43 and synapsin I, which mediate axonal and synaptic plasticity, respectively. Additionally, in silico predictions of baccharin showed favorable physicochemical properties, pharmacokinetics, drug-likeness, and medicinal chemistry friendliness. Altogether, these findings suggest that baccharin is a promising neurotrophic agent whose therapeutic application in neurodegeneration should be further investigated.",

It is the most common cause of irreversible blindness. With an increasing number of glaucoma patients and disease progression despite treatment, it is paramount to develop new and effective therapeutics. Emerging new candidates are the receptor agonists of the incretin hormone glucagon-like-peptide-1 (GLP-1), originally used for the treatment of diabetes. GLP-1 receptor (GLP-1R) agonists have shown neuroprotective effects in preclinical and clinical studies on neurodegenerative diseases in both the brain (e.g., Alzheimer's disease, Parkinson's disease, stroke and diabetic neuropathy) and the eye (e.g., diabetic retinopathy and AMD). However, there are currently very few studies investigating the protective effects of GLP-1R agonists in the treatment of specifically glaucoma.

The disease progresses slowly, and we can roughly differentiate two stages: early-stage (ESDR), in which there are mild retinal lesions and visual acuity is generally preserved, and advanced-stage (ASDR), in which the structural lesions are significant and visual acuity is compromised. At present, there are no specific treatments for ESDR and the current recommended action is to optimize metabolic control and maintain close control of blood pressure. However, in the coming years, it is foreseeable that therapeutic strategies based in neuroprotection will be introduced in the clinical arena. This means that screening aimed at identifying patients in whom neuroprotective treatment might be beneficial will be crucial. Regarding the treatment of ASDR, the current primary course is based on laser photocoagulation and intravitreal injections of anti-angiogenic factors or corticosteroids. Repeated intravitreal injections of anti-VEGF agents as the first-line treatment would be replaced by more cost-effective and personalized treatments based on the results of \"liquid biopsies\" of aqueous humor.

This study is aimed at detecting the influence of HDAC3 on the high-glucose-induced retinal ganglion cell death. The retinal HDAC3 expression in DR of different time points was analyzed by immunohistochemical assay and western blot. Besides, the expression of HDAC3 and both retinal thickness and RGC loss were analyzed. The effects of HDAC3 inhibitor on cell viability, oxidative stress, and apoptosis in high-glucose- (HG-) treated RGCs were analyzed. Both inflammatory and antioxidative factors were detected by ELISA. Advanced effects of HDAC3 inhibition on the expression of NLRP3 inflammasome were detected using western blots. High HDAC3 expression was detected only in the late DR mice (4 months of diabetes duration) but not early DR mice (2 months of diabetes duration). The immunohistochemical assay showed that HDAC3 expression was correlated with both retinal thickness and RCG contents. HDAC3 inhibitor significantly protected the HG-treated RGCs from damaged cell viability, severe apoptosis, and oxidative stress. Advanced pathway analyses showed that HDAC3 inhibition inactivated NLRP3 inflammasome and thus alleviated retinal inflammation. Conclusion. In conclusion, HDAC3 was involved in RGC loss and thus promoted the progression of neurodegeneration of DR. Besides, HDAC3 inhibitor demonstrated protective effects in neurodegeneration in DR through downregulation of NLRP3 activity. The effects of HDAC3 inhibitor in DR management should be confirmed in clinical trials.",

In general, our current knowledge and practice have failed to prevent the onset or progression of DR to sight-threatening complications. While there are treatment options for sight-threatening complications of DR, it is crucial to pay more attention to the early stages of DR to decrease its prevalence. Growing evidence suggests many pathologic changes occur before clinical presentations of DR in euglycemic hyperinsulinemia, prediabetes, and diabetes. These pathological changes occur in retinal neurons, glia, and microvasculature. A new focus on these preclinical pathologies - especially on hyperinsulinemia - may provide further insight into disease mechanisms, endpoints for clinical trials, and druggable targets in early disease. Here, we review the current evidence on the pathophysiological changes reported in preclinical DR and appraise preventive and treatment options for DR.",

Therefore, utilizing two models of microglia depletion, we aimed to deplete and repopulate microglia to clarify the contribution of microglia to neuronal loss and vascular damage in the diabetic retina in an STZ-induced model of hyperglycemia. Here, we report that 2\u00a0weeks exposure to diphtheria toxin (DTx) in diabetic CX3CR1CreER:R26iDTR transgenic mice induced a 62% increase in Iba1+ microglia associated with an increase in TUJ1+ axonal density and prevention of NeuN+RBPMS+ neuronal loss. Conversely, diabetic PBS controls exhibited robust TUJ1+ axonal and NeuN+RBPMS+ neuronal loss compared to non-diabetic controls. A 2-week recovery period from DTx was associated with a 40% reduction in angiogenesis and an 85% reduction in fibrinogen deposition into the diabetic retina in comparison to diabetic PBS-treated controls. Analysis of microglia morphology and marker expression revealed that following a 2-week recovery period microglia displayed a P2RY12+Ly6C- phenotype and high transformation index (TI) values complimented by a ramified-surveillant morphology closely resembling non-diabetic controls. In contrast, diabetic PBS-treated control mice displayed P2RY12+Ly6C+ microglia, with a 50% reduction in TI values with an amoeboid morphology. To validate these observations were due to microglia depletion, we used PLX-5622 to assess vascular and neuronal damage in the retinas of diabetic mice. Confocal microscopy revealed that PLX-5622 also induced an increase in TUJ1+ axonal density and prevented fibrinogen extravasation into the diabetic retina. mRNAseq gene expression analysis in retinal isolates revealed that PLX-5622-induced microglia depletion and repopulation induced a downregulation in genes associated with microglial activation and phagocytosis, B2m, Cx3cr1, and Trem2, and complement-associated synaptic pruning, C1qa, C1qb, and C1qc. Although the levels of microglia depletion induced with DTx in the CX3CR1CreER:R26iDTR model and those induced with the CSF-1R antagonists are distinct, our results suggest that microglia depletion and replenishment is neuroprotective by inducing the proliferation of a homeostatic microglia pool that supports neuronal and vascular integrity.",

The ability of these lab-grown retinal neurons to form new synaptic connections after dissociation from ROs is key to building confidence in their capacity to restore visual function. However, direct evidence of reestablishment of retinal neuron connectivity via synaptic tracing has not been reported to date. The present study employs an in\u00a0vitro, rabies virus-based, monosynaptic retrograde tracing assay [Wickersham et al., Neuron\u00a053, 639-647\u00a0(2007); Sun et al., Mol. Neurodegener.\u00a014,\u00a08\u00a0(2019)] to identify de novo synaptic connections among early retinal cell types following RO dissociation. A reproducible, high-throughput approach for labeling and quantifying traced retinal cell types was developed. Photoreceptors and retinal ganglion cells-the primary neurons of interest for retinal cell replacement-were the two major contributing populations among the traced presynaptic cells. This system provides a platform for assessing synaptic connections in cultured retinal neurons and sets the stage for future cell replacement studies aimed at characterizing or enhancing synaptogenesis. Used in this manner, in\u00a0vitro synaptic tracing is envisioned to complement traditional preclinical animal model testing, which is limited by evolutionary incompatibilities in synaptic machinery inherent to human xenografts.",

DR has non-proliferative stages, characterized in part by retinal neuroinflammation and ischemia, and proliferative stages, characterized by retinal angiogenesis. Several systemic factors, including poor glycemic control, hypertension, and hyperlipidemia, increase the risk of DR progression to vision-threatening stages. Identification of cellular or molecular targets in early DR events could allow more prompt interventions pre-empting DR progression to vision-threatening stages. Glia mediate homeostasis and repair. They contribute to immune surveillance and defense, cytokine and growth factor production and secretion, ion and neurotransmitter balance, neuroprotection, and, potentially, regeneration. Therefore, it is likely that glia orchestrate events throughout the development and progression of retinopathy. Understanding glial responses to products of diabetes-associated systemic dyshomeostasis may reveal novel insights into the pathophysiology of DR and guide the development of novel therapies for this potentially blinding condition. In this article, first, we review normal glial functions and their putative roles in the development of DR. We then describe glial transcriptome alterations in response to systemic circulating factors that are upregulated in patients with diabetes and diabetes-related comorbidities; namely glucose in hyperglycemia, angiotensin II in hypertension, and the free fatty acid palmitic acid in hyperlipidemia. Finally, we discuss potential benefits and challenges associated with studying glia as targets of DR therapeutic interventions. In vitro stimulation of glia with glucose, angiotensin II and palmitic acid suggests that: 1) astrocytes may be more responsive than other glia to these products of systemic dyshomeostasis; 2) the effects of hyperglycemia on glia are likely to be largely osmotic; 3) fatty acid accumulation may compound DR pathophysiology by promoting predominantly proinflammatory and proangiogenic transcriptional alterations of macro and microglia; and 4) cell-targeted therapies may offer safer and more effective avenues for DR treatment as they may circumvent the complication of pleiotropism in retinal cell responses. Although several molecules previously implicated in DR pathophysiology are validated in this review, some less explored molecules emerge as potential therapeutic targets. Whereas much is known regarding glial cell activation, future studies characterizing the role of glia in DR and how their activation is regulated and sustained (independently or as part of retinal cell networks) may help elucidate mechanisms of DR pathogenesis and identify novel drug targets for this blinding disease.",

Diabetic macular edema (DME) is an ocular complication in patients with diabetes, and it can impair vision significantly. DME is a disorder of the neurovascular system, and it causes obstructions of the retinal capillaries, damage of the blood vessels, and hyperpermeability due to the expression and action of vascular endothelial growth factor (VEGF). These changes result in hemorrhages and leakages of the serous components of blood that result in failures of the neurovascular units (NVUs). Persistent edema of the retina around the macula causes damage to the neural cells that constitute the NVUs resulting in diabetic neuropathy of the retina and a reduction in vision quality. The macular edema and NVU disorders can be monitored by optical coherence tomography (OCT). Neuronal cell death and axonal degeneration are irreversible, and their development can result in permanent visual loss. Treating the edema before these changes are detected in the OCT images is necessary for neuroprotection and maintenance of good vision. This review describes the effective treatments for the macular edema that are therefore neuroprotective.",

Current therapies consist of protocols aiming to alleviate the existing clinical signs associated with microvascular alterations limited to the advanced disease stages. In response to the low resolution and limitations of the DR treatment, there is an urgent need to develop more effective alternative therapies to optimize glycemic, vascular, and neuronal parameters, including the reduction in the cellular damage promoted by inflammation and oxidative stress. Recent evidence has shown that dietary polyphenols reduce oxidative and inflammatory parameters of various diseases by modulating multiple cell signaling pathways and gene expression, contributing to the improvement of several chronic diseases, including metabolic and neurodegenerative diseases. However, despite the growing evidence for the bioactivities of phenolic compounds, there is still a lack of data, especially from human studies, on the therapeutic potential of these substances. This review aims to comprehensively describe and clarify the effects of dietary phenolic compounds on the pathophysiological mechanisms involved in DR, especially those of oxidative and inflammatory nature, through evidence from experimental studies. Finally, the review highlights the potential of dietary phenolic compounds as a prophylactic and therapeutic strategy and the need for further clinical studies approaching the efficacy of these substances in DR management.",

Branched-Chain Amino Acids (BCAAs), as essential amino acids, perform a variety of biological functions, including protein synthesis, glucose metabolism, lipid metabolism, inflammation, and oxidative stress in metabolic tissues of diabetes and aging-related diseases. Recently, it has been shown that BCAAs are highly related to neuroprotection, oxidative stress, inflammatory and glutamate toxicity in the retina of retinopathy. Therefore, this review summarizes the alterations of BCAA levels in retinopathy, especially diabetic retinopathy and aging-related macular disease, and the genetics, functions, and mechanisms of BCAAs in the retina as well as other metabolic tissues for reference.

The SCN receives photic information exclusively through melanopsin-expressing retinal ganglion cells (mRGCs) to synchronize circadian rhythms with the environmental light cycles. The SCN is composed of two major peptidergic neuron types in the core and shell regions of the SCN. Determining how mRGCs interact with the network of synaptic connections onto and between SCN neurons is key to understand how light regulates the circadian clock and to elucidate the relevant local circuits within the SCN. To map these connections, we used a newly developed Cre-dependent electron microscopy (EM) reporter, APEX2, to label the mitochondria of mRGC axons. Serial blockface scanning electron microscopy was then used to resolve the fine 3D structure of mRGC axons and synaptic boutons in the SCN of a male mouse. The resulting maps reveal patterns of connectomic organization in the core and shell of the SCN. We show that these regions are composed of different neuronal subtypes and differ with regard to the pattern of mRGC input, as the shell receives denser mRGC synaptic input compared with the core. This finding challenges the present view that photic information coming directly from the retina is received primarily by the core region of the SCN.",

DR was recently defined as a neurovascular disease associated with tissue-specific neurovascular impairment of the retina in patients with diabetes. Neurovascular cell death is the main cause of neurovascular impairment in DR. Thus, neurovascular cell protection is a potential therapy for preventing the progression of DR. Growing evidence indicates that a variety of cell death pathways, such as apoptosis, necroptosis, ferroptosis, and pyroptosis, are associated with neurovascular cell death in DR. These forms of regulated cell death may serve as therapeutic targets for ameliorating the pathogenesis of DR. This review focuses on these cell death mechanisms and describes potential therapies for the treatment of DR that protect against neurovascular cell death.",

Glucagon-like peptide 1 exerts its effects by activating a membrane receptor identified in many tissues, including different brain regions. Glucagon-like peptide 1 activates several signaling pathways related to neuroprotection, like the support of cell growth/survival, enhancement promotion of synapse formation, autophagy, and inhibition of the secretion of proinflammatory cytokines, microglial activation, and apoptosis during neural morphogenesis. The glial cells, including astrocytes and microglia, maintain metabolic homeostasis and defense against pathogens in the central nervous system. After brain insult, microglia are the first cells to respond, followed by reactive astrocytosis. These activated cells produce proinflammatory mediators like cytokines or chemokines to react to the insult. Furthermore, under these circumstances, microglia can become chronically inflammatory by losing their homeostatic molecular signature and, consequently, their functions during many diseases. Several processes promote the development of neurological disorders and influence their pathological evolution: like the formation of protein aggregates, the accumulation of abnormally modified cellular constituents, the formation and release by injured neurons or synapses of molecules that can dampen neural function, and, of critical importance, the dysregulation of inflammatory control mechanisms. The glucagon-like peptide 1 receptor agonist emerges as a critical tool in treating brain-related inflammatory pathologies, restoring brain cell homeostasis under inflammatory conditions, modulating microglia activity, and decreasing the inflammatory response. This review summarizes recent advances linked to the anti-inflammatory properties of glucagon-like peptide 1 receptor activation in the brain related to multiple sclerosis, Alzheimer's disease, Parkinson's disease, vascular dementia, or chronic migraine.",

The microglial receptor, CX3CR1, binds to fractalkine (FKN), an anti-inflammatory chemokine that is expressed on neuronal membranes (mFKN), and undergoes constitutive cleavage to release a soluble domain (sFKN). Deficiencies in CX3CR1 or FKN showed increased microglial activation, inflammation, vascular damage, and neuronal loss in experimental mouse models. To understand the mechanism that regulates microglia function, recombinant adeno-associated viral vectors (rAAV) expressing mFKN or sFKN were delivered to intact retinas prior to diabetes. High-resolution confocal imaging and mRNA-seq were used to analyze microglia morphology and markers of expression, neuronal and vascular health, and inflammatory mediators. We confirmed that prophylactic intra-vitreal administration of rAAV expressing sFKN (rAAV-sFKN), but not mFKN (rAAV-mFKN), in FKNKO retinas provided vasculo- and neuro-protection, reduced microgliosis, mitigated inflammation, improved overall optic nerve health by regulating microglia-mediated inflammation, and prevented fibrin(ogen) leakage at 4 weeks and 10 weeks of diabetes induction. Moreover, administration of sFKN improved visual acuity. Our results elucidated a novel intervention via sFKN gene therapy that provides an alternative pathway to implement translational and therapeutic approaches, preventing diabetes-associated blindness.",

The drugs currently used for treatment, such as ranibizumab, mainly focus on the middle and late periods of DR, and thus do not meet the clinical need. Here, the potential mechanisms by which compound Danshen Dripping Pills (CDDP) might protect against early DR were investigated. Methods: Db/db mice were used to establish a DR model. The initial weights and HbA1c levels of the mice were monitored, and retinal pathology was assessed by hematoxylin-eosin (HE) staining. The vascular permeability of the retina and thickness of each retinal layer were measured, and electroretinogram were performed together with fundus fluorescein angiography and optical coherence tomography. The levels of inflammatory factors were examined in retinal tissue, as well as those of intercellular adhesion molecule 1 (ICAM-1), IL-6, and monocyte chemoattractant protein 1 (MCP-1) in the serum using ELISA. Immunohistochemistry was used to evaluate levels of vascular endothelial growth factor (VEGF), B-cell lymphoma 2 (Bcl-2), and Bclassociated X protein (Bax). Retinal cell injury and apoptosis were examined by TdT-mediated dUTP Nick End Labeling (TUNEL) assays. Results: The data showed that CDDP significantly improved cellular disarrangement. Imaging data indicated that CDDP could reduce vascular permeability and the amplitude of oscillatory potentials (OPs), and restore the thickness of the ganglion cell layer. Moreover, CDDP reduced the expression levels of inflammatory factors in both the retina and serum. Conclusion: These findings strongly suggest that CDDP prevents early DR through vascular and neuroprotection.",

Here, we conducted in vitro and in vivo ischemia/reperfusion (I/R) efficacy studies of a hybrid antioxidant-nitric oxide donor small molecule, SA-10, to assess its therapeutic potential for ocular stroke. To induce I/R injury and inflammation, we subjected R28 and primary microglial cells to oxygen glucose deprivation (OGD) for 6 h in vitro or treated these cells with a cocktail of TNF-\u03b1, IL-1\u03b2 and IFN-\u03b3 for 1 h, followed by the addition of SA-10 (10 \u00b5M).

In vivo I/R-injured mouse retinas were treated with either PBS or SA-10 (2%) intravitreally, and pattern electroretinogram (ERG), spectral-domain optical coherence tomography, flash ERG and retinal immunocytochemistry were performed. SA-10 significantly inhibited microglial activation and inflammation in vitro. Compared to the control, the compound SA-10 significantly attenuated cell death in both microglia (43% vs. 13%) and R28 cells (52% vs. 17%), decreased ROS (38% vs. 68%) production in retinal microglia cells, preserved neural retinal function and increased SOD1 in mouse eyes.

Visual deficits can present with delay and worsen over time, and may be associated with an ongoing neuroinflammatory response that is known to occur after TBI. Complement system activation is strongly associated with the neuroinflammatory response after TBI, but whether it contributes to vision loss after TBI is unexplored. Acute and chronic neuroinflammatory changes within the dorsal lateral geniculate nucleus (dLGN) and retina were investigated subsequent to a moderate to severe murine unilateral controlled cortical impact. Neuroinflammatory and histopathological outcomes were interpreted in the context of behavioral and visual function data. To investigate the role of complement, cohorts were treated after TBI with the complement inhibitor, CR2-Crry. At 3 days after TBI, complement component C3 was deposited on retinogeniculate synapses in the dLGN both ipsilateral and contralateral to the lesion, which was reduced in CR2-Crry treated animals. This was associated with microglia morphological changes in both the ipsilateral and contralateral dLGN, with a less ramified phenotype in vehicle compared to CR2-Crry treated animals. Microglia in vehicle treated animals also had a greater internalized VGlut2\u2009+\u2009synaptic volume after TBI compared to CR2-Crry treated animals. Microglia morphological changes seen acutely persisted for at least 49\u00a0days after injury. Complement inhibition also reduced microglial synaptic internalization in the contralateral dLGN and increased the association between VGLUT2 and PSD95 puncta, indicating preservation of intact synapses. Unexpectedly, there were no changes in the thickness of the inner retina, retinal nerve fiber layer or retinal ganglion layer. Neuropathological changes in the dLGN were accompanied by reduced visual acuity at subacute and chronic time points after TBI, with improvement seen in CR2-Crry treated animals. TBI induces complement activation within the dLGN and promotes microglial activation and synaptic internalization. Complement inhibition after TBI in a clinically relevant paradigm reduces complement activation, maintains a more surveillance-like microglia phenotype, and preserves synaptic density within the dLGN. Together, the data indicate that complement plays a key role in the development of visual deficits after TBI via complement-dependent microglial phagocytosis of synapses within the dLGN.",

However, it has remained a formidable challenge to decipher the genetic underpinnings that dictate the specific connections formed between neuronal types. To address this, we propose a novel bilinear modeling approach that leverages the architecture similar to that of recommendation systems. Our model transforms the gene expressions of presynaptic and postsynaptic neuronal types, obtained from single-cell transcriptomics, into a covariance matrix. The objective is to construct this covariance matrix that closely mirrors a connectivity matrix, derived from connectomic data, reflecting the known anatomical connections between these neuronal types. When tested on a dataset of Caenorhabditis elegans, our model achieved a performance comparable to, if slightly better than, the previously proposed spatial connectome model (SCM) in reconstructing electrical synaptic connectivity based on gene expressions. Through a comparative analysis, our model not only captured all genetic interactions identified by the SCM but also inferred additional ones. Applied to a mouse retinal neuronal dataset, the bilinear model successfully recapitulated recognized connectivity motifs between bipolar cells and retinal ganglion cells, and provided interpretable insights into genetic interactions shaping the connectivity. Specifically, it identified unique genetic signatures associated with different connectivity motifs, including genes important to cell-cell adhesion and synapse formation, highlighting their role in orchestrating specific synaptic connections between these neurons. Our work establishes an innovative computational strategy for decoding the genetic programming of neuronal type connectivity. It not only sets a new benchmark for single-cell transcriptomic analysis of synaptic connections but also paves the way for mechanistic studies of neural circuit assembly and genetic manipulation of circuit wiring.",

This approach utilizes high-resolution 3D printing of liquid-metal microelectrodes, enabling precise targeting of specific inner retinal layers within organoids. The adaptable distribution and softness of these microelectrodes facilitate the spatiotemporal recording of inner retinal signals. This study not only demonstrates the functional properties of RGCs in retinal organoid development but also provides insights into their synaptic connectivity, reminiscent of fetal native retinas.

Despite advancements in conventional treatments, the quest for more holistic approaches and fewer side effects persists. Traditional Chinese medicine (TCM) has been used for centuries in managing various diseases, including diabetes and its complications. This review evaluated the efficacy and underlying mechanisms of TCM in the management of DR, providing information on its potential integration with conventional treatment methods. A comprehensive literature review was conducted using PubMed, Web of Science, and the China National Knowledge Infrastructure (CNKI) with the search terms 'traditional Chinese medicine', 'diabetic retinopathy', 'clinical efficacies' and their combinations. Studies published before 2023 without language restriction were included, focusing on clinical trials and observational studies that assessed the effectiveness of TCM in DR treatment. The review synthesized evidence of empirical traditional Chinese formulas, traditional Chinese patent medicines, and isolated phytochemicals on DR treatment. The key mechanisms identified included the reduction of oxidative stress, inflammation, and neovascularization, as well as the improvement in neurovascular functionality and integrity of the retinal blood barrier.

In the brain, defects in \u03b3-aminobutyric acid synaptic transmission are associated with pathophysiological and neurodegenerative disorders, whereas glucagon-like peptide-1 has demonstrated neuroprotective effects. However, it is not yet clear whether diabetes causes alterations in inhibitory input to retinal ganglion cells and whether and how glucagon-like peptide-1 protects against neurodegeneration in the diabetic retina through regulating inhibitory synaptic transmission to retinal ganglion cells. In the present study, we used the patch-clamp technique to record \u03b3-aminobutyric acid subtype A receptor-mediated miniature inhibitory postsynaptic currents in retinal ganglion cells from streptozotocin-induced diabetes model rats. We found that early diabetes (4 weeks of hyperglycemia) decreased the frequency of GABAergic miniature inhibitory postsynaptic currents in retinal ganglion cells without altering their amplitude, suggesting a reduction in the spontaneous release of \u03b3-aminobutyric acid to retinal ganglion cells. Topical administration of glucagon-like peptide-1 eyedrops over a period of 2 weeks effectively countered the hyperglycemia-induced downregulation of GABAergic mIPSC frequency, subsequently enhancing the survival of retinal ganglion cells. Concurrently, the protective effects of glucagon-like peptide-1 on retinal ganglion cells in diabetic rats were eliminated by topical administration of exendin-9-39, a specific glucagon-like peptide-1 receptor antagonist, or SR95531, a specific antagonist of the \u03b3-aminobutyric acid subtype A receptor. Furthermore, extracellular perfusion of glucagon-like peptide-1 was found to elevate the frequencies of GABAergic miniature inhibitory postsynaptic currents in both ON- and OFF-type retinal ganglion cells. This elevation was shown to be mediated by activation of the phosphatidylinositol-phospholipase C/inositol 1,4,5-trisphosphate receptor/Ca 2+ /protein kinase C signaling pathway downstream of glucagon-like peptide-1 receptor activation. Moreover, multielectrode array recordings revealed that glucagon-like peptide-1 functionally augmented the photoresponses of ON-type retinal ganglion cells. Optomotor response tests demonstrated that diabetic rats exhibited reductions in visual acuity and contrast sensitivity that were significantly ameliorated by topical administration of glucagon-like peptide-1. These results suggest that glucagon-like peptide-1 facilitates the release of \u03b3-aminobutyric acid onto retinal ganglion cells through the activation of glucagon-like peptide-1 receptor, leading to the de-excitation of retinal ganglion cell circuits and the inhibition of excitotoxic processes associated with diabetic retinopathy. Collectively, our findings indicate that the \u03b3-aminobutyric acid system has potential as a therapeutic target for mitigating early-stage diabetic retinopathy. Furthermore, the topical administration of glucagon-like peptide-1 eyedrops represents a non-invasive and effective treatment approach for managing early-stage diabetic retinopathy.",

This study aimed to investigate the impact of brimonidine, a selective adrenoceptor agonist, on diabetic retinal neurodegeneration, recognizing the critical role of neurodegeneration in diabetic retinopathy. Streptozotocin-induced diabetes was established in adult male Sprague-Dawley rats to mimic diabetic retinopathy. Rats, except non-diabetic control rats, received topical applications of 0.15% brimonidine tartrate (treatment group) or balanced salt solution (diabetic control group) twice daily following diabetes induction. Each group comprised six randomly assigned animals. Retinal samples were analyzed using immunofluorescence staining, apoptosis assay, and western blot. Topical brimonidine treatment reduced apoptosis of retinal ganglion cells at 8 weeks after induction of diabetes (p<0.05). Glial activation induced by diabetes was reduced by brimonidine treatment. Immunoblot and immunofluorescence assay revealed that the decrease in phospho- protein kinase B (AKT) level resulting from diabetes was also attenuated by brimonidine (p<0.05). Furthermore, brimonidine alleviated the decrease in anti-apoptotic proteins [BCL2 apoptosis regulator (BCL2) and BCL-xl] induced by diabetes (p<0.05). Elevation of phospho-p38 mitogen-activated protein kinase (p38MAPK) and p53 in diabetic rats were reduced by brimonidine (p<0.05). Additionally, brimonidine treatment attenuated the upregulation of the pro-apoptotic molecule BCL-2 associated X in retinas of diabetic rats (p<0.05). These findings suggest that topical brimonidine treatment may protect retinal ganglion cells in experimental diabetes by modulating the AKT pathway and reducing pro-apoptotic p38MAPK levels. This presents a potential neuroprotective approach in diabetes, offering the advantage of localized treatment without the added burden of oral medication.",

With the rapid increase in the prevalence of DM, the incidence of DR is also rising year by year. Preventing and effectively treating DR has become a major focus in the medical field. Traditional Chinese medicine (TCM) has a wealth of experience in treating DR and has achieved significant results with various herbs and TCM prescriptions. Traditional Chinese Medicine (TCM) provides a comprehensive therapeutic strategy for diabetic retinopathy (DR), encompassing anti-inflammatory and antioxidant actions, anti-neovascularization, neuroprotection, regulation of glucose metabolism, and inhibition of apoptosis. This review provides an overview of the current status of TCM treatment for DR in recent years, including experimental studies and clinical researches, to explore the clinical efficacy and the underlying modern mechanisms of herbs and TCM prescriptions. Besides, we also discussed the challenges TCM faces in treating DR, such as drug-drug interactions among TCM components and the lack of high-quality evidence-based medicine practice, which pose significant obstacles to TCM's application in DR.",

This review article, focused on the critical role of neurotrophins in peripheral neuropathy, highlights the intricate balance of neurotrophins necessary for nerve health and the pathophysiological consequences when this balance is disturbed. Neurotrophins, including Nerve Growth Factor (NGF), Brain-Derived Neurotrophic Factor (BDNF), Neurotrophin-3 (NT- 3), and Neurotrophin-4 (NT-4), are essential for neuronal survival, axonal growth, and synaptic plasticity. Their signaling pathways are crucial for maintaining peripheral nervous system integrity, primarily via the Tropomyosin receptor kinase (Trk) receptors and the p75 neurotrophin receptor p75(NTR). Dysregulation of neurotrophins is implicated in various neuropathies, such as diabetic neuropathy and chemotherapy-induced peripheral neuropathy, leading to impaired nerve function and regeneration. Understanding neurotrophin signaling intricacies and their alterations in neuropathic conditions is crucial for identifying novel therapeutic targets. Recent advancements illuminate neurotrophins' potential as therapeutic agents, promising disease-modifying treatments by promoting neuronal survival, enhancing axonal regeneration, and improving functional recovery post-nerve injury. However, translating these molecular insights into effective clinical applications faces challenges, including delivery methods, target specificity, and the instability of protein- based therapies.",

However, the details of visual function restoration using this regenerative therapeutic approach have not yet been characterized. Here, we evaluated the electrophysiological properties of end-stage rd1 retinas after transplantation (TP-rd1) and compared them with those of wild-type (WT) retinas using multi-electrode arrays. Notably, retinal ganglion cells (RGCs) in TP-rd1 retinas acquired light sensitivity comparable to that of WT retinas. Furthermore, RGCs in TP-rd1 retinas showed light adaptation to a photopic background and responded to flickering stimuli. These results demonstrate that transplantation of gRO sheets may restore some fundamental physiological functions, possibly coordinating with the remaining functions in retinas with end-stage degeneration.",

The injury and loss of retinal ganglion cells are the primary pathological changes in several retinal degenerative diseases, including glaucoma, ischemic optic neuropathy, diabetic neuropathy, and optic neuritis. In mammals, injured retinal ganglion cells lack regenerative capacity and undergo apoptotic cell death within a few days of injury. Additionally, these cells exhibit limited regenerative ability, ultimately contributing to vision impairment and potentially leading to blindness. Currently, the only effective clinical treatment for glaucoma is to prevent vision loss by lowering intraocular pressure through medications or surgery; however, this approach cannot halt the effect of retinal ganglion cell loss on visual function. This review comprehensively investigates the mechanisms underlying retinal ganglion cell degeneration in retinal degenerative diseases and further explores the current status and potential of cell replacement therapy for regenerating retinal ganglion cells. As our understanding of the complex processes involved in retinal ganglion cell degeneration deepens, we can explore new treatment strategies, such as cell transplantation, which may offer more effective ways to mitigate the effect of retinal degenerative diseases on vision.",
        "40016944": "ID: 40016944\nTitle: The Effect of Advancing Age and Intraocular Pressure Injury on Retinal Ganglion Cell Function and Synaptic Connectivity.\nAbstract: Age and elevated intraocular pressure (IOP) are the two major risk factors for developing glaucoma, a leading cause of blindness worldwide that is characterized by the loss of retinal ganglion cells (RGCs). Although vision loss is irreversible over the long term, accumulating evidence points to short-term improvement of vision in glaucoma patients in response to certain interventions, suggesting that RGCs have the capacity to recover function. In the present study, we sought to investigate the mechanisms underlying loss and recovery of RGC function in response to aging and IOP injury, with a focus on synaptic connectivity. Using electroretinography, we found that advancing age was associated with a substantial reduction in function across all retinal layers in the absence of significant cell loss. A superimposed injury induced by IOP elevation led to the selective loss of RGC function in young and middle-aged mice that was associated with a decrease in paired excitatory synapses. RGC functional recovery after injury was significantly delayed in middle-aged mice and was mediated through different cellular mechanisms than in young mice. Whereas young mice regained excitatory synaptic inputs from bipolar cells, functional recovery in older mice was instead mediated through an increase in intrinsic RGC excitability, associated with modulation of the action potential threshold and axon initial segment length. Our findings provide new insights into the impact of advancing age on RGC resilience to IOP injury. Boosting the capacity for RGC recovery by reversing the effect of advancing age offers a new therapeutic approach for glaucoma management.",

The purpose of this study was to investigate the correlation of serum pro-BNP with optical coherence tomography (OCT) indices in diabetic retinopathy. This cross-sectional study investigated 96 consecutive subjects aged between 40 and 65 years: controls n = 24, no diabetic retinopathy (NoDR) n = 24, non-proliferative diabetic retinopathy (NPDR) n = 24, and proliferative diabetic retinopathy (PDR) n = 24. Same-day analysis of blood samples for serum pro-BNP levels was performed and spectral-domain OCT (SD-OCT) was used to measure the following OCT indices: OCT angiography (OCTA) superficial vessel density (SVD), deep vessel density (DVD), and foveal avascular zone (FAZ); OCT retinal nerve fiber layer (RNFL); and OCT ganglion cell analysis (GCA). The mean serum pro-BNP levels for the control, NoDR, NPDR, and PDR groups were 14.07 \u00b1 11.51, 27.35 \u00b1 11.81, 280.44 \u00b1 106.13, and 122.33 \u00b1 43.66 pg/ml, respectively. The mean values of the various OCT parameters correlated with serum pro-BNP were OCTA SVD (r = - 0.360), OCTA DVD (r = 0.408), OCTA FAZ (r = 0.475), OCT RNFL (r = - 0.215) and OCT GCA (r = - 0.285; p<0.001). The serum pro-BNP levels were higher in the NPDR group than in the NoDR group and much lower in the PDR group than in the NPDR group, reflecting a lowering of the protective barrier. These results correlated with the changes in various OCT indices.",

This cross-sectional study was carried out among 93 type 2 diabetic patients with early signs of DR (170 eyes), ranging from level 10 to level 35 based on ETDRS DR severity scale score. Age-, sex-, and axial length-matched normal subjects were enrolled as controls. Systemic inflammation biomarkers including neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and systemic immune-inflammatory index (SII) were calculated based on peripheral blood results. Retinal neuronal changes of RNVU were identified by accessing the thickness of macular retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) using OCT. Retinal microvascular alterations of RNVU were evaluated by measuring macular vessel density (VD) and size of foveal avascular zone (FAZ) using OCTA. GCL thickness was significantly correlated with NLR (r = -0.183, p = 0.017) and MLR (r = -0.235, p = 0.002), RNFL thickness was significantly associated with MLR (r = -0.210, p = 0.008), FAZp was positively correlated with NLR (r = 0.153, p = 0.046) and MLR (r = 0.187, p = 0.014), FAZa was positively correlated with MLR (r = 0.189, p = 0.014), and VD was significantly correlated with NLR (r = -0.188, p = 0.014) on spearman correlation analysis. Additionally, VD was independently associated with SII in both univariable and multivariable GLM analysis (p < 0.05). This difference still remained statistically significant during subgroup analysis after controlling DM duration. Systemic inflammation biomarkers including NLR, MLR, and SII are significantly associated with not only retinal microvascular alterations but also retinal neuronal changes, providing evidence that systemic inflammation may play a crucial role on the early morphological changes of RNVU and early DR pathogenesis. SII is independently associated with VD, which supports SII may serve as a potential biomarker for monitoring early microvascular changes of DR.",

This study aims to ascertain whether METTL14 influences m6A methylation of PHLPP2 in diabetic retinopathy (DR) and to delineate the precise function of the METTL14/PHLPP2 axis in disease progression. METTL14 levels were observed to be elevated in retinas of DR rats and in HG-stimulated RGCs, coinciding with an increase in PHLPP2 m6A modification. Knockdown of METTL14 resulted in significant reductions in PHLPP2 expression and its m6A modification. Silencing METTL14 mitigated HG-induced damage in RGCs, which was linked to the inhibition of apoptosis, oxidative stress and inflammation. This protective effect could be negated through the restoration of PHLPP2. METTL14 knockdown modulated the AKT/GSK-3\u03b2/Nrf2 signal cascade through PHLPP2. Silencing METTL14 resulted in the downregulation of METTL14 and PHLPP2 in the retinas of DR rats, ameliorated visual function impairment and reduced the pathological alterations. These protective effects of METTL14 silencing against DR were also weakened when PHLPP2 was restored. Overall, these results suggest that suppressing METTL14 improves HG-induced damage in RGCs and protects against DR by downregulating PHLPP2 through m6A modification.",

Seventeen human donor retinas were classified as diabetes mellitus (DM, n = 7), diabetes with diabetic retinopathy (DR, n = 3), or control (n = 8). Macular transversal sections were analyzed for photoreceptors, bipolar cells, horizontal cells, ganglion cells, their synaptic connections, and M\u00fcller cells using immunohistochemistry and confocal microscopy. The densities of bipolar cells, horizontal cells, and ganglion cells and the thickness of the inner plexiform layer (IPL) were quantified around the fovea. In the macula, cone photoreceptors elongated their axons to establish synapses with bipolar and horizontal cells in intraretinal cysts. Bipolar cells were reduced in the DM group compared to the control (P < 0.001), and rod bipolar cells showed morphological alterations in the cell body and synaptic terminals in both diabetic groups. Morphological changes were observed in both plexiform layers, with a decrease in the IPL thickness in DR. Horizontal cell terminals sprouted into the outer and inner retina in DR, despite no density differences existing between DM and control (P = 0.498). Ganglion cell density was reduced in the DM retinas compared to control (P < 0.001). M\u00fcller cells exhibited thickening of their cell bodies and end feet in all diabetic retinas. The degeneration of neurons and synaptic connectivity within the macula in individuals with DM, even in the absence of clinical vascular signs, is associated with impaired visual function. These early changes suggest potential new biomarkers for imaging techniques and emphasize the need for therapies for diabetic patients without clinical signs.",

Community-based, cross-sectional study. This study was conducted in a tertiary teaching hospital in Guangzhou, China. A total of 1325 ocular-treatment-naive participants, of whom 1115 had no DR and 210 had DR, were recruited in a community in Guangzhou, China. A commercially available OCTA device was used to obtain various peripapillary retinal microvascular metrics centred on the optic disc, including vessel density (VD), vessel length density (VLD) and vessel diameter index (VDI). The peripapillary RNFL thickness was automatically obtained using built-in software. Linear regression analyses were used to evaluate the association of the peripapillary OCTA parameters (VD, VLD and VDI), RNFL thickness with various DR stages and average RNFL thickness with peripapillary OCTA parameters. Moderate and severe DR had progressively decreased VD in the peripapillary ring (\u03b2 = -0.72, 95% CI = -1.31\u2009to -0.14 and -1.79, 95% CI = -2.81\u2009to -0.77, respectively) and other regions (all p<0.05). Similar changes were observed between peripapillary VLD and moderate and severe DR (all p<0.05). Moderate (\u03b2 = -4.56, 95% CI = -8.97\u2009to -0.15, p=0.043) and severe DR (\u03b2 = -10.12, 95% CI = -18.29\u2009to -1.95, p=0.015) had significant thinner peripapillary RNFL in the inferior quadrant. VD and VLD were linearly associated with the average RNFL in the peripapillary ring and average peripapillary area (all p<0.05). The peripapillary retinal microvasculature and RNFL were significantly reduced with the progression of DR, which suggests that monitoring differences in peripapillary microvasculature and the RNFL may be a promising approach to detecting DR progression.",

Retinal homeostasis is critically maintained by the retinal neurovascular unit (NVU), which can be disrupted by abnormal activation of microglia in DR. However, the underlying mechanism remains unclear. Here, we provide the first evidence of upregulated stimulator of interferon genes (STING) in microglia within fibrovascular membranes (FVMs) and retinas from oxygen-induced retinopathy (OIR) and streptozotocin (STZ)-induced diabetic mice. Furthermore, we identified STING upregulation in BV2 cells stimulated with high glucose (HG) or hypoxia, accompanied by mitochondrial dysfunction and cytoplasmic leakage of damaged mitochondrial DNA (mtDNA). Pharmacologic or genetic inhibition of STING in microglia prevented their activation and polarization. Next, we demonstrated that STING-deficient BV2 cells reversed the proangiogenic behavior of endothelial cells and protected retinal ganglion cells (RGCs) from oxidative stress. Finally, intravitreal injection of AAV-STING alleviated retinal neurovascular pathologies in both OIR and STZ mice. This study demonstrated that the release of mtDNA mediates STING immune activation of microglia, which further exacerbates NVU damage in DR. In contrast, immunosuppressing STING in microglia could serve as a potential therapeutic strategy.",
        "40175519": "ID: 40175519\nTitle: Sulforaphane protects developing neural networks from VPA-induced synaptic alterations.\nAbstract: Prenatal brain development is particularly sensitive to chemicals that can disrupt synapse formation and cause neurodevelopmental disorders. In most cases, such chemicals increase cellular oxidative stress. For example, prenatal exposure to the anti-epileptic drug valproic acid (VPA), induces oxidative stress and synaptic alterations, promoting autism spectrum disorders (ASD) in humans and autism-like behaviors in rodents. Using VPA to model chemically induced ASD, we tested whether activation of cellular mechanisms that increase antioxidant gene expression would be sufficient to prevent VPA-induced synaptic alterations. As a master regulator of cellular defense pathways, the transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) promotes expression of detoxification enzymes and antioxidant gene products. To increase NRF2 activity, we used the phytochemical and potent NRF2 activator, sulforaphane (SFN). In our models of human neurodevelopment, SFN activated NRF2, increasing expression of antioxidant genes and preventing oxidative stress. SFN also enhanced expression of genes associated with synapse formation. Consistent with these gene expression profiles, SFN protected developing neural networks from VPA-induced reductions in synapse formation. Furthermore, in mouse cortical neurons, SFN rescued VPA-induced reductions in neural activity. These results demonstrate the ability of SFN to protect developing neural networks during the vulnerable period of synapse formation, while also identifying molecular signatures of SFN-mediated neuroprotection that could be relevant for combatting other environmental toxicants.",

This study aimed to elucidate whether nitric oxide (NO) can modulate the TXNIP/NLRP3 inflammasome pathway and mitigate retinal neurovascular unit (NVU) damage during early DR. In an in vitro co-culture system, silencing TXNIP or NLRP3 in retinal microglia (RMG) significantly upregulated glial cell-derived neurotrophic factor (GDNF) and downregulated inducible nitric oxide synthase (iNOS) expression in retinal ganglion cells (RGC). Moreover, it resulted in decreased iNOS and vascular endothelial growth factor A (VEGFA) levels and enhanced the expression of tight junction proteins (Occludin and ZO-1) in retinal microvascular endothelial cells (RMEC), while also reducing NO release and inhibiting RMEC tube formation. Treatment with S-nitroso-N-acetyl penicillamine (SNAP), an NO donor, significantly downregulated TXNIP/NLRP3 inflammasome signaling in RMG, decreased RGC apoptosis, and inhibited tube formation in RMEC. It also upregulated GDNF, suppressed iNOS in RGC, decreased VEGFA, and improved tight junction proteins in RMEC. Treatment with 1400W, an iNOS inhibitor, resulted in decreased NO concentration and increased IL-1\u03b2 levels in the co-culture supernatant, without significantly affecting iNOS expression in RGC or RMEC. In an early DR rat model, Electroretinogram (ERG), Optical Coherence Tomography (OCT), Fluorescein Angiography (FFA), Evans blue assays, Immunofluorescence staining, and TUNEL staining confirmed that sodium nitroprusside (SNP), NO donor administration mitigated retinal neural and vascular dysfunction, and preserved retinal NVU integrity. Concurrently, SNP treatment reduced IL-1\u03b2 expression and increased GDNF and Occludin levels in the early DR retina. Genetic Association Database (GAD) enrichment analysis and protein-protein interaction (PPI) network validation indicated that NO functions as a downstream mediator of the TXNIP/NLRP3 inflammasome pathway and exhibits a strong association with DR. These findings suggest that NO mediates negative feedback in the TXNIP/NLRP3 inflammasome pathway to exert protective effects against retinal NVU dysfunction in early DR, thereby offering potential therapeutic strategies for early intervention in DR.",

Diabetic patients underwent detailed systemic and ophthalmic examination including automated pupillometry. The pupillometer used a white stimulus and was equipped with a high-resolution infrared (880\u2009nm) camera. Static pupillary diameters were captured at different levels of background intensity-photopic high (100\u2009cd/m2), photopic low (10\u2009cd/m2), mesopic high (1\u2009cd/m2), and mesopic low (0.1\u2009cd/m2). Dynamic pupillary responses were elicited with white-light flashes (total luminance 100\u2009cd/m2, stimulus on time 200\u2009ms, off time 3300\u2009ms). RNFL thickness was measured using spectral domain optical coherence tomography (OCT) RESULTS: The study had 38 diabetic patients with retinopathy (DWR), 27 diabetic patients without retinopathy (DWOR), and 25 healthy controls. Static pupillometry showed significant differences between the three groups. Diabetic patients, both with and without retinopathy had significantly smaller pupillary diameters compared to controls, (p\u2009<\u20090.001).

A cross-sectional prospective pilot study was conducted on two groups. We compared the results of functional tests (Pattern ERG and Pattern VEP - PERG and PVEP) and anatomical tests (macular and RNFL OCT) in a diabetic group without diabetic retinopathy to a control group. The \u03c72 test was used to study qualitative data, and the t test was used for quantitative data. The significance threshold was a P value less than 0.05.

The Ca2+/calmodulin-dependent protein kinase II alpha (CaMK2A) and cAMP response element-binding protein (CREB) signaling pathway has been implicated in various neurological disorders. However, its role in DR pathogenesis remains elusive. We established a DR mouse model by streptozotocin administration and performed histological, biochemical, and molecular analyses to investigate the involvement of CaMK2A/CREB signaling and its interplay with mitophagy. Additionally, we employed in vitro high-glucose (HG) treatment in primary mouse retinal ganglion cells to dissect the underlying mechanisms. Pharmacological and genetic modulations were utilized to target CaMK2A/CREB pathway and mitophagy. In the DR model, we observed retinal degeneration, increased apoptosis, and reduced neurotransmitter production, accompanied by enhanced mitophagy and activation of the CaMK2A/CREB pathway. HG induction in retinal ganglion cells recapitulated these findings, and autophagy inhibition partially rescued cell death but failed to suppress CaMK2A/CREB activation, suggesting mitophagy as a downstream consequence. CaMK2A knockdown or CREB phosphorylation inhibition attenuated HG-induced mitophagy, apoptosis, and neurotransmitter depletion, while CREB activation exacerbated these effects. CaMK2A silencing mitigated DR progression, oxidative stress, inflammation, and neuronal loss, akin to dopamine/carbidopa administration in DR mouse model. Our findings reveal the involvement of CaMK2A/CREB signaling activation and enhanced mitophagy in DR, suggesting these pathways may be therapeutically relevant targets for DR management.",

This was a cross-sectional study in 96 eyes of 67 patients, including controls, diabetes without DR (DMnoDR), nonproliferative DR (NPDR), and proliferative DR (PDR) groups. Participants underwent same-day quantitative contrast sensitivity function (qCSF) and 6 \u00d7 6 mm OCT angiography (OCTA) centered on the optic disc. The Peripapillary Nerve Fiber Layer Microvasculature Density algorithm (ARI Network) was used to calculate capillary perfusion density (total area of perfused microvasculature per unit area), capillary flux index (CFI, total weighted area of perfused microvasculature per unit area), and retinal nerve fiber layer (RNFL) thickness surrounding the optic disc. Mixed-effects multivariable regression models, controlling for age, hypertension, and lens status, evaluated associations between RPC OCTA metrics, DR severity, VA, and qCSF. Significant RPC microvascular changes were observed across DR stages. Capillary perfusion density decreased with DR severity and even before retinopathy onset in DMnoDR versus controls (\u03b2avg = -0.42, P\u00a0=\u00a00.021). PDR compared to NPDR showed a significant decrease in CFI (\u03b2 = -1.02 to -0.92, P < 0.01) and in RNFL (\u03b2avg = -0.71, P\u00a0=\u00a00.033). CFI had significant associations with qCSF at various spatial frequencies (\u03b2\u00a0=\u00a00.20 to 0.34, P\u00a0=\u00a00.002 to 0.042), but not with VA. Radial peripapillary capillary perfusion density worsens with onset of diabetes and increasing severity of DR while capillary flux index is more significantly affected later in disease. Structure-function associations suggest that DR-induced peripapillary microvascular changes are more strongly associated with contrast sensitivity changes than with visual acuity.",

Neurodegeneration of the retina is a process, in which retinal neurons suffer irreversible damage. This study aimed to assess the involvement of neurotrophins (brain-derived neurotrophic factor [BDNF] and nerve growth factor [NGF]) in the pathogenesis of DR.MethodsThe study was performed using male Lewis rats with type 1 diabetes mellitus induced by streptozotocin, and the control group included rats without drug administration. In vivo examinations performed over four weeks included eye fundus imaging, measurement of intraocular pressure, and glycemia. After sacrifice, serum and eyeballs were harvested. Post-mortem analyses included a histopathological analysis of the retina and the measurement of BDNF and NGF levels in the serum and eyeball homogenate.ResultsIn the experimental group, early-stage DR was confirmed, and changes in the retina were observed: diabetic rats had relatively thicker outer nuclear layers and relatively thinner inner plexiform layers. A lower level of BDNF was observed in the serum of rats with DR, while the level of NGF in the eyeball homogenate positively correlated with vascular changes.ConclusionsThe observed changes in the levels of neurotrophins in early-stage DR may indicate their involvement in the disease pathogenesis.",

The purpose of this study was to investigate the correlation of serum pro-BNP with optical coherence tomography (OCT) indices in diabetic retinopathy. This cross-sectional study investigated 96 consecutive subjects aged between 40 and 65 years: controls n = 24, no diabetic retinopathy (NoDR) n = 24, non-proliferative diabetic retinopathy (NPDR) n = 24, and proliferative diabetic retinopathy (PDR) n = 24. Same-day analysis of blood samples for serum pro-BNP levels was performed and spectral-domain OCT (SD-OCT) was used to measure the following OCT indices: OCT angiography (OCTA) superficial vessel density (SVD), deep vessel density (DVD), and foveal avascular zone (FAZ); OCT retinal nerve fiber layer (RNFL); and OCT ganglion cell analysis (GCA). The mean serum pro-BNP levels for the control, NoDR, NPDR, and PDR groups were 14.07 \u00b1 11.51, 27.35 \u00b1 11.81, 280.44 \u00b1 106.13, and 122.33 \u00b1 43.66 pg/ml, respectively. The mean values of the various OCT parameters correlated with serum pro-BNP were OCTA SVD (r = - 0.360), OCTA DVD (r = 0.408), OCTA FAZ (r = 0.475), OCT RNFL (r = - 0.215) and OCT GCA (r = - 0.285; p<0.001). The serum pro-BNP levels were higher in the NPDR group than in the NoDR group and much lower in the PDR group than in the NPDR group, reflecting a lowering of the protective barrier. These results correlated with the changes in various OCT indices.",

Retrospective, cross-sectional diagnostic evaluation. DR patients with PRP were categorized into those without OAG (Group 1) and those with OAG (Group 2). Peripapillary retinal nerve fiber layer (pRNFL) thickness and macular vessel density (VD) were measured, and the vertical difference in pRNFL (vdRNFL) and VD (vdVD) was determined as the absolute difference between the superior and inferior sectors. Diagnostic performance was analyzed by calculating the area under the curve (AUC). Analyses included 128 eyes (Group 1: 68 and Group 2: 60). The mean pRNFL thickness was 93.9 \u00b1 14.8 \u00b5m in Group 1 and 85.5 \u00b1 14.4 \u00b5m in Group 2 (P = .009). The mean vdRNFL was 13.1 \u00b1 10.9 \u00b5m in Group 1 and 14.4 \u00b1 12.6 \u00b5m in Group 2 (P = .607). The mean VD was 15.9 \u00b1 3.3 mm-1 in Group 1 and 15.3 \u00b1 2.6 mm-1 in Group 2 (P = .380), whereas the vdVD was 0.6 \u00b1 0.6 mm-1 in Group 1 and 1.6 \u00b1 1.4 mm-1 in Group 2 (P < .001). The AUC for diagnostic accuracy was 0.812 for vdVD, significantly higher than that for other factors (all P < .001). Relying on pRNFL thickness for OAG evaluation in PRP-treated patients is not recommended. Analysis of vertical microvasculature asymmetry can serve as a useful factor for diagnosing OAG.",

The current research examines the involvement of miR-29a-5p in regulating apoptosis, oxidative stress, and inflammation of retinal ganglion cells (RGCs) generated by High Glucose (HG). Additionally, we are interested in analyzing the contribution of miR-29a-5p in DRdeveloping. We obtained peripheral blood samples from 7 people with DR and 14 individuals without DR. Subsequently, we conducted biochemical indices analyses and qRT-PCR.We randomly divided RGCs into low glucose groups, HG groups, HG + inhibitor negative control groups, and HG\u00a0+\u00a0miR-29a-5p inhibitor groups. SIRT3 siRNA was transfected into RGCs through lipofectamine 3000 reagent.Cell vitality was detected by MTT; qRT-PCR was applied to identify miR-29a-5p expression; Detectionof ROS, SOD, and MDAlevels was quantified using the DCFH-DA, WST-1, and colorimetric methods, respectively; IL-6 and TNF-\u03b1contents were analyzed utilizing ELISA; Dual-luciferase gene reporter experiment was used to examine if SIRT3 is the specific target gene of miR-29a-5p; Flow cytometryevaluatedapoptosisin RGCs; The technique of Western blotting identified the presence of caspase-3 proteins. The expression of miR-29a-5p was markedly elevated in individuals with DR, and it had positive correlations with levels of Total Cholesterol (TC) and Fasting Blood Glucose (FBG).High glucose significantly induced RGC apoptosis and upregulated the miR-29a-5p gene. Transfection of miR-29a-5p inhibitor protected RGCs against HG-induced oxidative injury, inflammation, and apoptosis. Furthermore, the dual-luciferase reporter experiment provided confirmation that SIRT3 was a target gene of miR-29a-5p, as it negatively regulated SIRT3 expression. Notably, SIRT3 knockdown abolished the protection of miR-29a-5p inhibition on RGCs. Suppression of the miR-29a-5p gene safeguards RGCs against harm caused by HG via boosting SIRT3 signaling, which might provide a new prevention and treatment strategy for DR.",

However, the detailed molecular regulatory mechanism has not yet been thoroughly examined. In this study, primary mouse RGCs were stimulated with different concentrations of glucose, and mouse was intraperitoneally injected with streptozotocin (STZ) to construct DR model in vitro and in vivo. We found that compared to normal controls, RNA binding motif protein 15 (RBM15) was significantly upregulated in high glucose-treated RGCs and STZ-induced mice. RBM15 silence restored cell viability and inhibited cell apoptosis and cell death in high glucose-triggered RGCs. In parallel, RBM15 knockdown distinctly improved pathological damage such as thinning of retinal tissue thickness and loss of RGCs in STZ-modeling mice. Interestingly, the production of inflammatory cytokines and the expression of Cleaved caspase-1, NLRP3 and GSDMD-N were significantly reduced by RBM15 silence in vivo and in vitro. Mechanistically, RBM15 bound to kruppel like factor 6 (KLF6) mRNA to promote m6A modification and stabilize KLF6 mRNA, upregulating KLF6 expression in model cells and model mice retinal tissues. KLF6 overexpression increased the production of inflammatory cytokines and the expression of proteins related to pyroptosis, reversing the protective effects of RBM15 silence in high glucose-treated RGCs and diabetic retina. In conclusion, RBM15 is upregulated by high glucose, and stabilizes KLF6 mRNA to activate NLRP3-mediated pyroptosis pathway, exacerbating inflammation and apoptosis of RGCs and accelerating the progression of DR.",

This is a prospective observational cohort study based on the baseline and 1-year follow-up data of the Guangzhou Diabetic Eye Study. Type 2 diabetes mellitus patients without retinopathy were recruited. Thicknesses of ganglion cell inner plexiform layer (GC-IPL) and peripapillary retinal nerve fiber layer (pRNFL) were measured via swept-source optical coherence tomography. The associations between SUA level change and the thinning rates of GC-IPL and pRNFL were analyzed using multivariate linear regression analysis. Sub-group analysis based on sex was constructed. A total of 1084 participants were enrolled in our study. After adjustment, both male and female patients with decreased SUA levels in higher baseline SUA level group had a significantly slower thinning rate of GC-IPL than those with non-decreased SUA levels. In higher baseline SUA level with decreased SUA level group, male patients exhibited significantly slower thinning rate of inferior GC-IPL, while female patients exhibited significantly slower thinning rate of inferior and nasal GC-IPL and inferior pRNFL, when compared to those with non-decreased SUA levels. Our findings prove that decreased SUA level is associated with a slower GC-IPL thinning rate in higher baseline SUA level group, suggesting that decreased SUA level could be constituted as a potential future control target to delay the neurodegeneration in type 2 diabetes mellitus patients.",

This study enrolled 182 eyes with type 2 diabetes mellitus (DM) eyes and 202 healthy control eyes. The eyes of DM patients were divided into DM without DR (DM/noDR; n = 136) and DR stage groups (n = 46). Macular NVU parameters consisted of ganglion cell-inner plexiform layer (GCIPL) thickness and macular perfusion density (PD). As for peripapillary NVU parameters, peripapillary retinal nerve fiber layer (RNFL) thickness, together with radial peripapillary capillary perfusion density (RPC-PD) and RPC flux index (RPC-FI), represented by peripapillary structural and functional vascular parameters, were also examined. Macular and peripapillary parameters were compared among three stages, and correlations between macular and peripapillary parameters were examined for each stage. Macular GCIPL thickness and macular PD decreased with stage progression, preserving positive correlations (i.e., preserving macular NVU) with each other in all eyes, but correlation coefficients were the lowest in DM/noDR eyes. Macular GCIPL thickness, as well as macular PD, positively correlated with peripapillary NVU parameters over the entire stages except macular PD and RNFL thickness in DR eyes (i.e., preserving macular and peripapillary NVU), but correlation coefficients were the lowest in DM/noDR eyes. Macular and peripapillary NVU were preserved throughout the stages: control, DM/noDR, and DR groups, but the linkage weakened at the onset of DM, suggesting diabetes-induced dysregulation of macular and peripapillary NVUs in subclinical DR.",

In this study, we examined whether EMPA protects against N-methyl-d-aspartic acid (NMDA)-induced retinal excitotoxicity and the mechanisms underlying its protective effects. Male Sprague-Dawley rats (7-8\u00a0weeks old) were used in this study. The number of cells in the ganglion cell layer (GCL) decreased 7\u00a0days after intravitreal injection of NMDA (50\u00a0nmol). Simultaneous intravitreal injection of EMPA (50 and 100\u00a0nmol) and NMDA reduced NMDA-induced cell loss in a dose-dependent manner. The protective effect of EMPA was significantly attenuated by the AMP-activated protein kinase (AMPK) inhibitor, compound C (10\u00a0nmol). NMDA increased the number of terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive cells in the GCL 6\u00a0h after injection, and the response was significantly, but not completely, attenuated by EMPA. These results suggest that EMPA protects against NMDA-induced retinal excitotoxicity in rats. The protective effect of EMPA may be partly attributed to the activation of the AMPK pathway and inhibition of neuronal cell apoptosis.",
        "40759398": "ID: 40759398\nTitle: MiRNA-122-5p promotes retinal ganglion cell oxidative damage by targeting DJ-1 in hyperglycemic retina.\nAbstract: Mitochondrial dysfunction, induced by prolonged hyperglycemia, is widely regarded as a central factor in oxidative stress and retinal ganglion cell (RGC) degeneration in diabetic retinopathy (DR). DJ-1 (PARK7) acts as a crucial antioxidant defense mechanism, stabilizing mitochondrial structure and redox balance. However, its expression is dramatically suppressed under diabetic conditions, and the upstream regulatory mechanisms remain incompletely characterized. Growing evidence from epigenetic research implicates microRNAs (miRNAs) as important players in the molecular pathways underlying DR progression. Among these, miRNA-122-5p has drawn increasing attention due to its aberrant activity under diabetic stress and its putative interaction with PARK7. In this study, we employed a streptozotocin-induced type 1 diabetes mouse model and glucose-stimulated R28\u00a0cells to explore the contribution of miRNA-122-5p to mitochondrial damage, oxidative stress, and RGC injury. In diabetic mice, we observed significant oxidative imbalance, increased apoptotic activity, RGC loss, and diminished retinal function. MiRNA profiling identified miRNA-122-5p as the most upregulated among candidate miRNAs. Inhibition of miRNA-122-5p attenuated these pathological changes and preserved both cellular integrity and visual function. In vitro, high glucose triggered mitochondrial fragmentation, membrane potential collapse, and excessive reactive oxygen species generation in R28\u00a0cells. Suppressing miRNA-122-5p alleviated these injuries. Dual-luciferase assays confirmed that miRNA-122-5p directly targets PARK7, thereby post-transcriptionally repressing DJ-1 expression and compromising mitochondrial resilience. These findings establish miRNA-122-5p as a critical upstream regulator of DJ-1-mediated antioxidant defense. By aggravating mitochondrial oxidative stress, it contributes to RGC vulnerability in DR. Targeted modulation of miRNA-122-5p may offer a novel therapeutic approach to preserve retinal neurons and counteract neurodegeneration in DR.",

While current therapies primarily target vascular dysfunction, they offer limited neuroprotective benefits. In this study, we developed a novel light-responsive hydrogel composed of hyaluronic acid methacryloyl (HAMA) for the co-delivery of aflibercept and miR-21-3p antagomir (HAMA@(Ab+M21A)). This dual-therapeutic strategy was designed to concurrently target retinal vascular dysfunction and neurodegeneration. Upon light exposure, HAMA hydrogel undergoes rapid in situ crosslinking, exhibiting excellent ocular biocompatibility and sustained drug release over 45\u00a0days, in parallel with controlled biodegradation. HAMA@(Ab+M21A) effectively inhibits VEGF-induced vascular dysfunction, suppresses reactive gliosis, and promotes retinal ganglion cell survival in vitro and in vivo. Collectively, this study demonstrates the therapeutic potential of HAMA@(Ab+M21A) as a dual-function strategy for DR, providing both anti-angiogenic and neuroprotective effects to impede disease progression.",

In this study, we aimed to use in silico simulations to identify a U.S. Food and Drug Administration (FDA)-approved drug that can bind to the Cav3.1 T-type calcium channel. We used the automated docking suite GOLD v5.5 with the genetic algorithm to simulate molecular docking and predict the protein-ligand binding modes, and the ChemPLP empirical scoring function to estimate the binding affinities of 2,115 FDA-approved drugs to the human Cav3.1 channel. Drugs with high binding affinity and appropriate pharmacodynamic and pharmacokinetic properties were selected for molecular mechanics Poisson-Boltzmann surface area (MMPBSA) and molecular mechanics generalised Born surface area (MMGBSA) binding free energy calculations, GROMACS molecular dynamics (MD) simulations and Monte Carlo Cell (MCell) simulations. The docking results indicated that the FDA-approved drug montelukast has a high binding affinity to Cav3.1, and data from the literature suggested that montelukast has the appropriate drug-like properties to cross the human blood-brain barrier and reach synapses in the central nervous system. MMPBSA, MMGBSA, and MD simulations showed the high stability of the montelukast-Cav3.1 complex. MCell simulations indicated that the blockage of Cav3.1 by montelukast reduced the number of synaptic vesicles being released from the pre-synaptic region to the synaptic cleft, which may reduce the probability and amplitude of postsynaptic potentials.",

The mechanisms leading to neuro-retinal cell loss before vascular complications manifest in diabetes remain poorly understood. In this study, we investigated the neuronal RNA-binding protein HuD as a novel regulator of neuro-retinal degeneration in the early stage of diabetes. We determined the expression of HuD and alpha-crystallin A (CRYAA) in the retinal ganglion cell layer. HuD and CRYAA were down-regulated in the retinas of streptozotocin-induced diabetic rats and in neuro-retinal cells (R-28) treated with high glucose. Cryaa mRNA was identified as a novel target transcript of HuD, and we demonstrated that HuD post-transcriptionally regulates the expression of Cryaa mRNA by binding to its 3'-untranslated region. Silencing and overexpression of HuD positively regulated the expressions of Cryaa mRNA and protein. We demonstrated that the increase in inflammatory cytokines such as TNF\u03b1, IL-1\u03b2, and IL-6 in R-28 cells under hyperglycemic conditions was a result of both CRYAA and HuD levels. Silencing HuD and CRYAA enhanced high glucose-induced R-28 cell death, whereas their overexpression alleviated this effect. HuD post-transcriptionally regulates CRYAA expression, influencing the function and viability of neuro-retinal cells under diabetic conditions. Our results suggest that the HuD/CRYAA axis plays a crucial role in neuro-retinal cells and has the potential to serve as a prognostic factor and therapeutic target for diabetic neuro-retinal degeneration.",

As antibodies are unable to distinguish NRXN family members and isoforms, the purpose of this study was to investigate differential expression of individual NRXN transcripts in relevant retinal cell types in early DRD. RNAscope multiplexed fluorescent in situ hybridization was used to quantify transcripts of NRXNs in mouse and human retina. DM was induced in C57BL/6J mice using streptozotocin (STZ) and the retinal phenotype characterized by electroretinogram (ERG), optical coherence tomography (OCT), and optokinetic tracking (OKT) after 6 weeks. Retinal ganglion cells (RGCs) were generated in vitro by directed differentiation from human embryonic stem cells (hESCs), cultured in normal or high glucose, and NRXN expression assessed by qPCR and Western blot. All NRXN family members (NRXN1, NRXN2, and NRXN3) were enriched in inner retinal neurons in both human and mouse tissue. We identified decreased Nrxn3 transcripts, specifically the Nrxn3\u03b2 isoform, in RGCs of diabetic mice at 6 weeks after STZ treatment. Interestingly, Nrxn3\u03b1 and Nrxn3\u03b2 were differentially expressed in inner retinal layers. Finally, we confirmed decreased Nrxn3\u03b2 expression in hESC-RGCs cultured in high glucose in vitro. Our findings suggest that NRXNs may play cell-type-specific roles in the inner retina and associate decreased Nrxn3\u03b2 expression in RGCs with inner retinal dysfunction in early DRD.",
        "40860138": "ID: 40860138\nTitle: Intermittent fasting reprograms the brain proteome to prevent synaptic degeneration and cognitive impairment in vascular dementia.\nAbstract: Rationale: Vascular dementia (VaD), driven by chronic cerebral hypoperfusion (CCH), leads to synaptic degeneration and cognitive decline, yet mechanisms linking vascular dysfunction to synaptic loss remain unclear. Intermittent fasting (IF) has emerged as a potential intervention, but its effects on synaptic integrity in VaD are unknown. This study aims to investigate the effects of IF against synaptic degeneration and cognitive impairment induced by CCH. Methods: Bilateral common carotid artery stenosis (BCAS) was employed to induce chronic CCH by placing 0.18 mm micro-coils around each common carotid artery in mice. To assess temporal differences, the coils remained in place for 1, 7, 14, or 30 days. IF was implemented for 16 hours daily over three months prior to BCAS induction. Cognitive impairment was evaluated using the Barnes maze test. White matter lesions (WMLs) and neuronal loss were assessed using Luxol fast blue and cresyl violet staining, respectively. Immunoblotting and immunohistochemistry were performed to quantify synaptic protein levels. Synaptic integrity was examined using transmission electron microscopy. Proteomic analysis of the hippocampus was conducted to investigate molecular adaptations to IF following CCH. Results: We demonstrate that a 16-hour IF regimen preserves cognitive function and synaptic density despite persistent hypoperfusion. Behavioral assays revealed that IF prevented spatial memory deficits in BCAS mice, while electron microscopy confirmed synaptic preservation without altering baseline architecture. Surprisingly, key synaptic protein levels remained unchanged, suggesting IF protects synaptic function rather than abundance. Proteomic profiling revealed dynamic hippocampal adaptations under IF, including upregulation of synaptic stabilizers, enhanced GABAergic signaling, and suppression of neuroinflammatory mediators. CCH induced microglial engulfment of synapses, suggesting a role in complement-mediated synaptic pruning. Temporal pathway analysis revealed IF's multi-phase neuroprotection: early synaptic reinforcement, mid-phase metabolic optimization, and late-phase suppression of chronic neuroinflammation. Conclusion: These findings establish IF as a potent modulator of synaptic resilience in VaD, acting through coordinated preservation of synaptic structure, inhibition of inflammatory synapse loss, and metabolic reprogramming. Our results highlight IF's potential as a non-pharmacological strategy to combat vascular cognitive impairment by targeting the synaptic vulnerability underlying dementia progression.",

This cross-sectional study included 169 eyes of 169 NDR subjects and 54 eyes of 54 healthy controls. pRNFL, choroidal thickness and volume were compared and measured with UWF-SS-OCTA. The association between pRNFL and choroidal parameters was assessed with Spearman correlation analysis. Further multivariate linear regression analysis was performed to evaluate their relationship after adjusting for confounding factors. Compared with healthy controls, NDR patients showed reduced choroidal thickness and volume in the full range and several peripapillary subfields, while a statistical decrease of pRNFL was only detected in the inferior quadrant (P\u00a0=\u00a00.04). Regarding the distribution profiles in the peripapillary region, the choroid was thickest in the temporal region and thinnest in the inferior region, and a more prominent decrease compared with controls was found in the inferior region. Average pRNFL thickness was independently associated with full-range mean choroidal volume in multiple regression analysis (\u03b2\u00a0=\u00a00.16, P\u00a0=\u00a00.04).

Early glaucomatous damage is often associated with dendritic and synaptic abnormalities in RGCs, yet the mechanisms linking these synaptic alterations to RGC death remain unclear. In a mouse model of glaucoma, treatment with the clinical-stage, synaptogenic small molecule SPG302, a pegylated benzothiazole derivative, demonstrated neuroprotective effects, protecting RGCs and their axons in the glaucomatous retina and also improving retinal function as assessed by pattern electroretinogram testing. Elevated intraocular pressure disrupted synapses, as evidenced by reduced synaptophysin expression and homeostatic increases in Bassoon and PSD95 levels in the inner plexiform layer. SPG302 treatment effectively preserved synaptic integrity by reversing these changes.

This cross-sectional, comparative, and observational study included 96 participants, categorized into four groups: A1 (patients with T1DM, n = 24), A2 (age- and sex-matched nondiabetic controls for A1, n = 24), B1 (patients with T2DM, n = 24), and B2 (age- and sex-matched nondiabetic controls for B1, n = 24). Evaluations included retinal nerve fiber layer (RNFL) thickness, ganglion cell complex (GCC) thickness, central macular thickness (CMT), visual acuity, color vision, and contrast sensitivity. The primary objective was to compare RNFL, GCC, and CMT between T1DM and T2DM patients with equivalent disease duration and their respective controls. Secondary analyses assessed differences in visual acuity, color vision, and contrast sensitivity between T1DM and T2DM patients. The mean age of T2DM patients was 50.96 years, and for T1DM patients it was 28.96 years. T2DM patients exhibited significant GCC reduction in the superonasal ( P = 0.046) and inferonasal quadrants ( P = 0.048) compared to T1DM. T2DM also showed significant RNFL thinning in the superior ( P = 0.037), inferior ( P = 0.012), and temporal quadrants ( P = 0.025) compared to T1DM after adjustment for age and DM duration. No significant difference in CMT was observed between T1DM and T2DM. In T1DM patients, mean best-corrected visual acuity was significantly worse than that of controls ( P = 0.019). Contrast sensitivity and color vision did not differ significantly between T1DM and T2DM. This study reveals earlier RNFL and GCC thinning in T2DM compared to T1DM.",

Prospective observational cohort study. T2DM patients without clinical retinopathy at baseline and after a 2-year follow-up, along with age- and sex-matched healthy controls, were recruited from the community in Guangzhou, China. Measurements of macular GCIPLT, retinal thickness (RT), and SCP vessel density were conducted at baseline and at the 2-year follow-up. Linear mixed-effects models were used to estimate absolute and relative rates of changes and to compare absolute rates between the 2 groups. A total of 282 eyes (141 in the control group and 141 in the non-DR group) were included in the analysis. Significant reductions in GCIPLT and GCIPLT/RT occurred only in the non-DR group, with GCIPLT decreasing by -0.229 \u00b5m/y (95% CI = -0.313 to -0.144; P < .001) and 0.324 % (95% CI = 0.444 to 0.204; P < .001), approximately 5-fold faster than in the control group. After adjusting for confounding factors, the longitudinal rates of RT, GCIPLT, and GCIPLT/RT were significantly accelerated in the non-DR group compared to the control group by -0.603 \u00b5m/y (95% CI = -0.939 to -0.268; P < .001), -0.189 \u00b5m/y (95% CI = -0.306 to -0.073; P = .001), and -0.073 % (95% CI = -0.118 to -0.028; P = .001), respectively.

        "41002420": "ID: 41002420\nTitle: The Form and Function of Retinal Ganglion Cells in Diabetes.\nAbstract: This review examines how diabetes affects the ganglion cells of the retina, including the axons that make up the optic nerve. Links between established changes in the morphology of retinal ganglion cells (RGCs) and vision loss, as well as other functions, such as the pupillary light reflex, are considered. RGC morphology and function are significantly altered in both animal models and humans with diabetes. Diabetes affects all parts of the RGC, including the dendrites, the cell body, the axons making up the nerve fiber layer, and the optic nerve. Subtypes of RGCs appear to be affected differently by diabetes, and the morphology and electrophysiological output are more significantly affected in ON-RGCs than in OFF cells, which may explain part of the mechanism underlying the widely documented diabetes-induced reduction in contrast sensitivity. Furthermore, the morphology of the specialized light-sensitive melanopsin-containing RGCs also appears to be affected by diabetes, which may explain deficits in circadian rhythm and the pupillary light reflex. Potential therapeutic approaches aimed at protecting RGCs in diabetes are also discussed. Overall, strong evidence supports the conclusion that diabetes impacts the form and function of RGCs and their axons within the optic nerve, resulting in deficient regulation of circadian rhythms and the pupillary light reflex, in addition to vision.",

So, early diagnosis and proper treatment can preserve the useful vision in lifetime. The objective of the study was to determine the importance of ganglion cell complex (GCC) analysis as a parameter for diagnosis of glaucoma. This case control study was conducted in the Department of Ophthalmology, Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) General Hospital, Bangladesh over a period of one year from July 2017 to June 2018. Twenty five (25) Type-2 Diabetes control subjects and 50 subjects with Type-2 diabetes were divided into two groups, 25 diabetic with pre perimetric and 25 diabetic with perimetric glaucoma. In this study, there was no significant difference in age (50.92\u00b15.53 years vs. 52.44\u00b14.75 years vs. 52.64\u00b17.80 years), gender. Regarding Optical coherence tomography (OCT) Retinal Nerve Fiber Layer (RNFL) of right eyes of the study subjects, superior and inferior RNFL were significantly thinner in both pre-perimetric right eye (109.18\u00b18.95 and 111.21\u00b110.53) and perimetric right eye (90.28\u00b18.94 and 91.51\u00b17.87) comparing normal eyes (129.12\u00b12.68 and 132.17\u00b13.22). Superior and inferior RNFL were significantly lower in both pre-perimetric (110.13\u00b111.53 and 113.75\u00b19.61) and perimetric (95.93\u00b115.08 and 93.29\u00b112.68) left eyes comparing normal left eyes (129.71\u00b15.50 and 132.57\u00b15.22). Regarding OCT GCC layer of right eyes of the study subjects, superior and inferior GCC layer were significantly lower in both pre-perimetric (87.66\u00b13.81 and 89.70\u00b14.98) and perimetric (77.48\u00b16.97 and 79.21\u00b16.06) right eyes comparing normal eyes (104.53\u00b12.73 and 106.88\u00b13.29). Regarding OCT GCC layer of left eyes of the study subjects, superior and inferior GCC layer were significantly lower in both pre-perimetric (84.88\u00b13.82 and 87.21\u00b13.77) and perimetric (81.08\u00b19.51 and 80.01\u00b110.02) left eyes comparing normal eyes (102.64\u00b12.29 and 105.20\u00b11.27). GCC parameter is useful tool for diagnosis of Glaucoma. It has same ability to discriminate eyes with glaucoma and non glaucomatous eyes compared to RNFL. In glaucoma, GCC layer is significantly thin which correlates strongly with glaucomatous damage. According to our result GCC layer analysis is important investigation to diagnosis of Glaucoma.",

Hyperglycemia-induced formation of Advanced Glycation End products (AGEs) exacerbates metabolic dysfunction. While the Akt- FoxO1 axis has been the conventional focus of insulin signaling, recent findings highlight the upregulation of TOX4 in T2DM, obesity, and preclinical models (e.g., db/db mice). The cAMP signaling pathway has been shown to modulate TOX4 expression. This review synthesizes findings from recent in vivo and in vitro studies investigating the role of TOX4 in hepatic metabolism. The study focuses on its regulatory mechanisms, interaction with insulin signalling pathways, and its modulation through pharmacological inhibition. TOX4 inhibition significantly reduces glucose output in hepatocytes and improves glucose tolerance in animal models. While TOX4 ablation fails to reverse metabolic impairments caused by insulin receptor knockout, it nonetheless attenuates hepatic glucose production under insulin- resistant states. Additionally, TOX4 suppression shows hepatoprotective effects and may offer potential neuroprotection in the context of diabetic complications. TOX4 represents a promising therapeutic target for managing T2DM and its comorbidities. Further investigation into selective TOX4 inhibitors and their long-term safety profiles could facilitate the development of adjunct therapies for metabolic disorders involving hepatic and neuronal dysfunction.",

Exendin-4 (Ex-4), a widely used glucagon-like peptide-1 receptor (GLP-1R) agonist drug in the treatment of type 2 diabetes mellitus, has been reported to protect against ischemia-reperfusion (IR) injury in various vital organs. However, the potential neuroprotective effect of Ex-4 under RIR injury has been poorly understood. Immunofluorescence staining assay, hematoxylin and eosin (HE) staining were conducted to evaluate the neuroprotective role of Ex-4. A co-culture assay of human retinal vascular endothelial cells (HRVECs) and RGCs was established. Extracellular vesicles (EVs) were isolated from the culture supernatant of HRVECs with (E-EVs) or without Ex-4 treatment (O-EVs) under oxygen-glucose deprivation/reoxygenation (OGD/R) condition. Transmission electron microscopy (TEM), Nanoparticle tracking analysis (NTA) and Nano-flow cytometry (NanoFCM) were used to detect the presence and purity of EVs. Cell activity, reactive oxygen species (ROS) level, and cell death rate of RGCs were evaluated. Further global miRNA sequencing was performed on E-EVs or O-EVs to explore potential mechanisms. Our findings revealed that Ex-4\u00a0had a GLP-1R-dependent neuroprotective effect on RGCs. Vascular endothelial cells (VECs) -derived EVs mediate the protective effect of Ex-4 on RGCs under acute RIR injury. We identified miR-450b-5p as a highly enriched miRNA in E-EVs. Treatment with either E-EVs or miR-450b-5p mimics significantly protected RGCs against RIR-induced injury. Mechanistic investigations identified acyl-coenzyme A (CoA) synthetase long-chain family member 4 (ACSL4) as a direct target of miR-450b-5p. Ex-4 exerts its neuroprotective effects under RIR injury by stimulating retinal VECs to secrete miR-450b-5p-enriched EVs, thereby revealing a novel endothelial-mediated neuroprotective pathway in ischemia diseases.",

This study aimed to investigate the multiple nutraceutical properties of aqueous extracts prepared from colored peppers. Vitamin C content and phytochemical profiles of these peppers were analyzed. In vitro effects of anti-oxidative, anti-\u03b1-amylase, anti-\u03b1-glucosidase, anti-lipase and anti-acetylcholinesterase (AchE) of pepper aqueous extracts at 0.25, 0.5 and 1 mg were evaluated. The neuronal protective potent of pepper aqueous extracts at 0.5 and 1 mg in high glucose treated nerve growth factor (NGF)-differentiated PC12 cells were examined. Vitamin C content in these peppers was in the range of 60-96 mg/100 g fresh weight. The content of phenolic acids, flavonoids, anthocyanins and triterpenoids in these peppers was in the range of 860-2185 mg/100 g dry weight. Pepper aqueous extracts at 0.25, 0.5 and 1 mg exhibited concentration-dependent radical scavenging effects, ironchelating effects and reducing power, as well as effectively inhibited \u03b1-amylase, \u03b1-glucosidase, lipase and AchE activities. High glucose increased Bax mRNA expression, decreased mitochondrial membrane potential and Na+-K+ ATPase activity, caused DNA fragmentation and massive Ca2+ release, stimulated oxidative and inflammatory responses, and led to death of NGF-differentiated PC12 cells. Pre-treatments of pepper aqueous extracts at 0.5 and 1 mg reversed these changes, and increased the viability of NGF-differentiated PC12 cells. These novel findings suggest that colored peppers offered many bio-functions, which might benefit the prevention of diabetes associated complications such as diabetic neuropathy.",

The brain-derived neurotrophic factor (BDNF) has been implicated in neuroprotection and neural plasticity, yet its regulation and involvement in retinal neurodegenerative diseases remain largely unclear. In this study, we investigated the impact of BDNF deficiency in immune cells on retinal integrity. Using mice with a conditional BDNF knockout in microglia/macrophages and T-cells or selectively in microglia/macrophages, we analyzed retinal changes at 3 and 7 months of age, with wildtype mice as controls. BDNF-deficient mice exhibited early and progressive degeneration of retinal ganglion cells and photoreceptors, accompanied by pronounced astrogliosis, which was exacerbated in aged animals. In 7-month-old mice, adaptive changes in synapses could be documented, evidenced through enhanced expression of the vesicular acetylcholine transporter. These findings demonstrate that BDNF from immune cells plays a crucial role in maintaining retinal homeostasis and that its loss promotes retinal neurodegeneration. Targeting immune cell-derived BDNF may offer novel therapeutic strategies for retinal involvement in neurodegenerative diseases with implications for treatment of glaucoma or multiple sclerosis.",

Bacopa monniera (Scrophulariaceae), enriched with the neuroactive saponin Bacoside A (BA), has demonstrated neuroprotective potential. This study explored the molecular mechanisms underlying the neuroprotective effects of B. monniera extract (BME) against streptozotocin (STZ)-induced toxicity in SH-SY5Y neuroblastoma cells. In silico ADMET analysis revealed that BA and its sapogenins possess favorable pharmacokinetic profiles, including enhanced absorption, reduced toxicity, and improved clearance, supporting their bioactive role in BME. Pretreatment with BME (25\u00a0\u03bcg/mL) significantly (p\u00a0<\u00a00.01) reduced STZ-induced mitochondrial (51.24\u00a0%) and membrane (41.69\u00a0%) damage, as shown by MTT and LDH assays. BME markedly reduced intracellular ROS, protein carbonylation, and lipid peroxidation (p\u00a0<\u00a00.001), while restoring mitochondrial membrane potential, ATP levels, enzymatic antioxidant levels, and glutathione content. Furthermore, BME upregulated brain-derived neurotrophic factor (BDNF) expression and inhibited AGE formation. Collectively, these findings highlight the antioxidant, antiglycation, and neurotrophic actions of BME, underscoring its promise as a multi-targeted phytotherapeutic candidate for DN management.",

Evidence suggests that additional vascular and neurodegenerative mechanisms may be involved. This study aimed to characterise the thickness of the Ganglion Cell Complex (GCC) and investigate the Choroidal Vascularity Index (CVI) in patients with different patterns of therapeutic response to AVEGF DME. This cross-sectional study included 27 diabetic patients into 3 different groups based on their response to AVEGF therapy: control group, responder DME group, and persistent DME group. The study's approach to vascular and neurodegenerative imaging biomarkers involved three steps: (1) Automatic quantification of GCC thickness, with manual correction when necessary; (2) Semi-automatic measurement of choroidal thickness; and (3) Analysis of choroidal area and choroidal luminal area using ImageJ software to calculate the CVI. In the overall characterization of the sample, a significant difference was observed only in the Best Corrected Visual Acuity (BCVA). There was a significant difference in Average Retinal Thickness (1\u00a0mm, 3\u00a0mm, and 6\u00a0mm) between the 3 groups and in GCC thickness at 1\u00a0mm. BCVA was negatively correlated with mean retinal thickness, while CVI showed a potential positive correlation with BCVA. While demographic and general clinical characteristics showed minimal differences across the groups, important differences in GCC and choroidal characteristics were observed. GCC (1\u00a0mm) may be interesting to explore in predicting visual outcomes after treatment, and CVI may impact visual gain.",

Current therapeutic strategies often focus on symptomatic relief rather than addressing the underlying pathophysiology. Emerging evidence highlights the therapeutic potential of phytobioactives with robust anti-inflammatory and antioxidant properties as promising alternatives for diabetic neuropathy management. Phytobioactives such as flavonoids, polyphenols, alkaloids, and terpenoids demonstrate significant potential by mitigating oxidative stress, inhibiting pro-inflammatory cytokines, and promoting neuroprotection. Furthermore, combination approaches utilizing the synergistic effects of these phytobioactives have shown enhanced efficacy in preclinical models, targeting multiple pathways involved in the progression of diabetic neuropathy. However, clinical translation is hindered by challenges including low bioavailability, chemical instability, and suboptimal dosage. This review explores the mechanistic roles, preclinical evidence, and clinical challenges of phytobioactives in diabetic neuropathy therapy, emphasizing the need for advanced formulation strategies and well-designed clinical trials to optimize their therapeutic potential. Leveraging these phytobioactives could pave the way for more effective and holistic diabetic neuropathy treatments.",

A matched subset of 140 eyes (70 with ACP, 70 without) was selected based on age, sex, diagnosis, laterality, and number of injections. RNFL thickness (overall and by quadrant) was measured at baseline and one-year follow-up. Additional outcomes included IOP, visual acuity (VA), and central retinal thickness (CRT).ResultsThe matched cohort had a mean age of 71.06\u202f\u00b1\u202f11.44 years, with 61.4% female participants. ACP eyes had worse baseline VA, higher IOP, and thicker CRT (p\u2009<\u20090.050, for all), but showed greater VA improvement (p\u2009=\u20090.023) and a trend towards greater CRT reduction (p\u2009=\u20090.061).

Ginkgo biloba extract (GBE) has demonstrated neuroprotective properties, however, its specific mechanisms in DR remain incompletely understood. This research aims to elucidate the underlying mechanisms of GBE in DR. A diabetic rat model was induced with streptozotocin (STZ) and divided into control, diabetic, and GBE-treated groups. Retinal tissues of each group were analyzed using histology, TUNEL staining, and immunofluorescence. Bioinformatics identified potential GBE targets for DR, and protein-protein interaction network analysis prioritized core targets. Western blot and immunoprecipitation assays were used to detect protein expression and ubiquitination status. We successfully constructed the DR rat models and observed that GBE intervention effectively reverses diabetes-induced hyperglycemia and mitigates retinal ganglion cell (RGC) damage in the DR rat model. TUNEL staining indicates GBE's protective role against RGC apoptosis induced by DR. Bioinformatics identified 135 GBE targets in DR, with a focus on apoptosis pathways. Critically, we demonstrated an upregulation of TP53 expression in the retinal tissues of the DR rat model, an effect that was successfully reversed following GBE intervention. Notably, GEB increased TP53 ubiquitination, suggesting a potential modulation of TP53 stability and function. GBE attenuates DR progression by modulating TP53 ubiquitination in a rat model. The findings highlight the potential therapeutic benefits of GBE in DR and suggest further investigation into its mechanisms and broader bioactivity pathways.",

It is found in several countries worldwide and has numerous health-related benefits, including neuroprotection, anticancer, and anti-inflammatory effects. U. dioica has shown potential efficacy in treating diabetic neuropathy. This study aimed to systematically review the neuroprotective effects of U. dioica in diabetic models and explore the relationship between molecular and behavioral outcomes. A comprehensive search was conducted in several databases, including PubMed, Web of Science, Scopus, Science Direct, and the Cochrane Library. Only preclinical studies conducted on diabetic animal models with neural dysfunction were included. Eligible studies were required to have specific controlled groups and evaluate neural outcomes through behavioral tests or molecular investigations. Two authors independently extracted data according to the predefined inclusion and exclusion criteria. Of the 1398 studies identified, 11 met the inclusion criteria and were included in this review. U. dioica has been demonstrated to have beneficial effects in mitigating diabetes-induced neural dysfunction. These effects are likely mediated through mechanisms such as reducing oxidative stress and neuroinflammation, modulating insulin signaling pathways, and promoting neurogenesis. Evidence has shown that U. dioica consumption has positive effects on neuronal density in diabetes-affected neural tissues.

Beyond chronic hyperglycemia, hyperhomocysteinemia (HHcy) has emerged as a significant modulator of DR progression. This review delineates the multifaceted role of HHcy in disrupting the retinal neurovascular unit, detailing its pathogenic impact on endothelial cells, neurons (particularly retinal ganglion cells), glial cells, and the retinal pigment epithelium. The molecular mechanisms involve a synergistic interplay of oxidative stress, inflammation, endoplasmic reticulum stress, mitochondrial dysfunction, and epigenetic dysregulation, culminating in blood-retinal barrier breakdown, neurodegeneration, and pathological angiogenesis. While preclinical evidence robustly demonstrates a direct and synergistic effect of homocysteine with hyperglycemia in driving retinal injury, clinical associations remain contentious due to heterogeneity in study populations, confounding factors like renal function, and methodological variations. We critically evaluate this translational evidence and explore the therapeutic potential of targeting homocysteine metabolism through B vitamins, betaine, and other strategies. Despite promising preliminary data, the field requires well-designed randomized controlled trials, informed by lessons from cardiovascular research, to definitively establish HHcy as a modifiable risk factor and to validate the efficacy of precise, personalized interventions for DR.",

Studies, including our own, demonstrate that SRR is linked to a complication of diabetes, diabetic retinopathy (DR), and deletion of Srr protects diabetic animals from developing retinopathy. We investigate the feasibility and mechanisms of SRR inhibition as a strategy to prevent DR. SRR proteins in the retinas of db/db mice were approximately 50\u00a0% higher than C57BLKS/J wild-type (WT) mice, while D-serine levels in the aqueous humor were more than two-fold higher. Oral gavage of l-aspartic acid \u03b2-hydroxamate (L-ABH) improved b-wave amplitudes in electroretinogram recordings under both photopic and scotopic conditions. It also protected the inner retina in db/db mice by reducing the loss of retinal ganglion cells, endothelial cells, and pericytes, as well as decreasing the activation of M\u00fcller cells. In high glucose and hypoxia, interleukin-1 and interleukin-18 mRNA levels were lower in Srr-deleted M\u00fcller cell cultures than in WT cultures. Intravitreal injection of L-ABH mitigated glutamate-induced neurotoxicity in the retina. Systemically, L-ABH maintained euglycemia and improved glucose tolerance in db/db mice by inhibiting liver gluconeogenesis through restricting the expansion of pancreatic islet \u03b1-cells. Altogether, our results demonstrate that SRR inhibition prevents retinopathy in diabetic animals by blocking excitotoxicity and M\u00fcller cell-mediated inflammation in the retina, while also maintaining glucose homeostasis. This is the first demonstration that pharmacological blockade of SRR improves retinopathy and normalizes glucose levels in a type 2 diabetes model.",

We performed bulk RNA-Seq on endothelial and retinal cells, separately, at 1, 3, and 6 mo of diabetes and single-cell RNA-Seq (scRNA-Seq) at 3 months. Transcriptomics changes were validated by in vitro and ex vivo assays and immunohistochemistry of mouse and human tissue. Bulk RNA-Seq revealed inflammation in endothelial cells at 1 mo. At 3 mo, scRNA-Seq identified glutamine-driven anaplerotic dysfunction in M\u00fcller cells, confirmed by retinal culture. We posited this glutamine deficiency would impact the photoreceptors and endothelial cells. We validated this hypothesis using endothelial cells in vitro, and immunohistochemistry of disrupted photoreceptor ribbon synapses in mouse and human diabetic retinas. In addition, glutamine deprivation increased the expression of apoptotic genes in endothelial cells. At 6 mo, we observed significant down-regulation of angiogenic pathways and elevated profibrotic markers. Our results suggest that dysfunction of the metabolic ecosystem linking the M\u00fcller-photoreceptor-endothelial cells is central to the early stages of DRD pathogenesis, impacting photoreceptor synapses and endothelial cells, before the appearance of the classic microvascular features of DR.",

In this study, we investigated the neuroprotective potential of eucalyptol in a streptozotocin-induced rat model of diabetic neuropathy. We found that eucalyptol treatment significantly reduced thermal and mechanical hypersensitivity, lowered blood glucose and glycated hemoglobin, improved insulin levels and favorably regulated lipid profiles by decreasing total cholesterol, triglycerides and low-density lipoprotein cholesterol (LDL-C) while increasing high-density lipoprotein cholesterol (HDL-C). Antioxidant defenses were strengthened, as evidenced by elevated superoxide dismutase, catalase and glutathione-S-transferase activities, alongside reduced malondialdehyde levels. Eucalyptol also exhibited anti-inflammatory effects by inhibiting nuclear factor kappa B (NF-\u03baB) activation and lowering tumor necrosis factor-\u03b1lpha (TNF-\u03b1) and interleukin-6 (IL-6) expression. Histopathological analysis revealed preserved neuronal cytoarchitecture and reduced degeneration in the brain, along with regeneration of \u03b2-cells and restoration of islet morphology in the pancreas. Restoration of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF), both key neurotrophins supporting neuronal growth and survival, reflected enhanced neuronal survival and regeneration, further supported by electron microscopic evidence of sciatic nerve repair and remyelination. Collectively, we conclude that eucalyptol provided neuroprotection via glucose-lowering, antioxidant, anti-inflammatory and neurotrophic actions, highlighting its therapeutic potential.",

Here we provide both preclinical and clinical evidence demonstrating the neuroprotective effects of metformin in the context of retinal ganglion cell (RGC) degeneration, a hallmark of glaucoma, a leading cause of irreversible blindness for which no direct RGC-neuroprotective therapies are currently available. In a mouse model of retinal ischemia/reperfusion injury systemic administration of metformin significantly prevented RGC loss and preserved retinal structure. Enhanced phosphorylation of AMP-activated protein kinase (AMPK) was observed, along with increased autophagosome formation and upregulation of key mitophagy markers - including LC3II, optineurin, and Parkin - indicating improved mitochondrial quality control mechanisms. Proteomic analysis revealed that metformin modulated several proteins implicated in mitochondrial respiratory function, ubiquitination, and intracellular trafficking, suggesting broader effects on retinal cellular homeostasis. Complementing our preclinical observations, a retrospective clinical study in diabetic patients with glaucoma showed that individuals treated with metformin maintained stable visual field (VF) parameters over a six-month period, whereas those treated with insulin exhibited significant VF deterioration. These findings position metformin as a promising intraocular pressure (IOP)-independent neurotherapeutic for slowing or preventing glaucomatous neurodegeneration.",

Hypoglycemia induces endoplasmic reticulum stress and retinal cell death in mice, and low-glucose conditions induce macroautophagy/autophagy defects in 661W photoreceptor cells and retinal explants. Very few studies have analyzed the effect of hypoglycemia on retinal autophagy, so we decided to fill this gap. (2) Methods: We use C57BL/6 and GFP-LC3 mice and isolated retinal ganglion cells (RGCs) from both mouse models to study the autophagy process. (3) Results: Intraocular injection of rapamycin and 5 h hypoglycemia showed an increase in autophagosomes formation, specifically in the RGCs. Isolated GFP-LC3 RGCs showed an increase in autophagosome formation under low-glucose conditions. In contrast, infection of isolated C57BL/6 RGCs with the RFP-GFP-LC3 lentivirus revealed a defect in autophagosome/lysosome fusion under these conditions. (4) Conclusions: This study showed that 5 h hypoglycemia induces autophagosomes formation in mouse RGCs; however, a defect in the fusion process inhibits the protective effect of autophagy. Therefore, modulating both autophagic and apoptotic pathways might be important to avoid complications associated with DR.",

Little is known about repair of pathways/circuits after traumatic brain injury (TBI), which results in disruption of connectivity. Here we utilize a mouse model of diffuse traumatic axonal injury (impact-acceleration TBI) in order to explore, for the first time, the evolution of structural and functional changes in the terminal fields of the injured visual system. Retinal ganglion cell (RGC) axons and synapses were genetically labeled via AAV transduction, while anterograde and transsynaptic tracers were used to mark terminals and postsynaptic cells. Functional connectivity and visual integrity were assessed by monitoring c-Fos expression following light stimulation and pattern-reversal visual evoked potentials (pVEPs). Our findings demonstrate that, although TAI results in an \u223c50% loss of RGC axons and terminals, surviving RGCs undergo collateral sprouting, a form of compensatory branching of surviving axons, that restores terminal density to preinjury levels. Transsynaptic tracing and c-Fos mapping confirmed the reestablishment of connectivity, which was also associated with significant improvements in visual function as measured by pVEPs. Interestingly, the recovery process exhibited sexual dimorphism, with female mice showing delayed or incomplete repair. Moreover, collateral sprouting proceeded normally in Sarm1 knock-out mice, evidence of some independence from Wallerian degeneration. Our findings show that collateral sprouting may be an important mechanism of circuit repair in TAI and may represent a promising target for therapeutic interventions.",

However, accumulating evidence indicates that retinal neurodegeneration is also crucial in DR pathogenesis. Retinal ganglion cells (RGCs), the output neurons of the retina, are particularly vulnerable to diabetic stress. Cellular senescence has been implicated in diabetes-related tissue damage, but its contribution to RGC degeneration remains unclear. We hypothesized that diabetes contributes to retinal neurodegeneration by inducing senescence in RGCs. Methods In streptozotocin (STZ)-induced diabetic mice, retinal function was assessed via full-field electroretinography (ERG), and molecular changes were evaluated in senescence markers. The expression of p16INK4a and monocyte chemotactic protein-1 (MCP-1) in retinal tissue was evaluated by enzyme-linked immunosorbent assay (ELISA) and quantitative real-time polymerase chain reaction (qRT-PCR), and the localization of p16INK4a was confirmed by immunostaining. To explore the direct effects of senescence, primary RGCs isolated from rat retina were exposed to oxidative stress or treated with the CDK4/6 inhibitor palbociclib. The isolated RGCs were analyzed via senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) staining and live-cell neurite imaging. Results The STZ-induced diabetic mice exhibited significant hyperglycemia without weight loss. ERG revealed markedly reduced amplitudes of the a-wave, b-wave, and oscillatory potentials, indicating impaired retinal neural function. Molecular analyses revealed significant upregulation of MCP-1 and p16INK4a at mRNA and protein levels. Immunostaining demonstrated p16INK4a co-expression in a subset of NeuN-positive cells within the ganglion cell layer, suggesting RGC senescence. Palbociclib-induced senescence (confirmed by SA-\u03b2-gal positivity) in vitroresulted in progressive neurite shortening in RGCs. Similarly, oxidative stress induced by antioxidant-free culture conditions caused neurite degeneration, highlighting the dual contributions of oxidative stress and senescence to RGC injury. Conclusions Cellular senescence was identified as a critical mechanism underlying RGC dysfunction in diabetes. Diabetes was found to induce retinal senescence and senescence-associated secretory phenotype activation, with RGCs exhibiting senescence-associated changes. Moreover, oxidative stress and pharmacologically induced senescence directly impaired RGC morphology and function in vitro. These results expanded our understanding of DR from a solely vascular disorder to a neurodegenerative disease, providing mechanistic insights into the role of senescence in retinal aging and neuronal susceptibility in diabetes.",

Isolated OA with adult-onset, milder phenotypes in WS1 is rare and typically associated with biallelic AR mutations. We describe 7 patients of pauci-syndromic WS1 presenting with adult-onset OA and compare parameters of visual function with other OA-predominant syndromes. A retrospective review was performed identifying records of patients seen at our institution from January 1, 2020, through December 31, 2024, who were found to have OA secondary to mutations in OPA1 (n = 9), WFS1 (n = 7), POLG (n = 3), mutations causing Leber hereditary optic neuropathy (LHON) (n = 17) or isolated OA from other genetic causes (n = 7). Patients were excluded who harbored confounding causes of vision loss and nongenetic causes of OA. Clinical data of visual function were recorded, including mean deviations and foveal sensitivities on automated visual fields (AVF), and ganglion cell complex (GCC) and peripapillary retinal nerve fiber layer (RNFL) thickness on optical coherence tomography (OCT). Visual acuities from initial neuro-ophthalmology consultation were recorded in logMAR format. Statistical analysis was performed on continuous variables. This study was granted exempt status by our institutional IRB. Compared with other OA syndromes, patients with LHON had the most severe average AVF and foveal sensitivity depressions and the lowest presenting logMAR acuity. Patients with WS1 in our cohort had significantly later onset of symptoms and delayed presentation compared with other OA syndromes. Patients with WS1 were significantly more likely to present with arcuate scotomas compared with other genetic OA syndromes, while patients with LHON and patients with OPA1 mutations (autosomal dominant optic atrophy [ADOA]) presented commonly with central scotomas and blind spot enlargement, respectively. WS1 diagnosis was not significantly associated with any specific pattern of thinning on OCT of the RNFL or GCC. ADOA diagnosis was associated with the most peripapillary RNFL thinning overall of all OA syndromes, most significantly in the superior and inferior quadrants. Our cohort of patients with WS1 showed uncharacteristically mild vision loss and minimal syndromic features, suggesting that a milder alternative phenotype with WFS1 mutations is possible in contrast to the traditional DIDMOAD syndrome. Compared with other OA syndromes, these patients with WS1 showed significant associations with arcuate visual field defects and trends toward superior/inferior peripapillary RNFL thinning. This suggests that relative preservation of papillomacular bundle fibers and thus milder central visual acuity loss may be a unifying feature in their phenotype. This series expands the clinical spectrum of WS1 and should encourage further work to study the pathogenic role of wolframin in vision loss. Clinicians should consider Wolfram syndrome in cases of adult-onset, symmetric, near-isolated OA, especially in cases with arcuate field defects, which are more commonly seen than in other genetic syndromes.",

Chitosan, a biocompatible polysaccharide with antioxidant, anti-inflammatory, and lipid-lowering properties, may exert direct neuroprotective effects. This study evaluated the impact of oral administration of chitosan on peripheral nerve function and structure in a murine model of streptozotocin (STZ)-induced diabetes. Male C57BL/6 mice were divided into three groups: Sham, untreated diabetics (T1DM) and diabetics treated with chitosan (150 mg/kg/day, 12 weeks). Metabolic, behavioral (Open Field), nociceptive (Von Frey, Tail-Flick), electrophysiological (compound motor action potential-CMAP) and histological (intraepidermal nerve fiber density-IENF) parameters were analyzed. Chitosan did not significantly modify blood glucose (p = 0.3366), but showed favorable metabolic effects, reducing LDL cholesterol in T1DM+Chitosan vs. T1DM mice (43.75 \u00b1 5.62 mg/dL vs. 82.75 \u00b1 7.65 mg/dL, p < 0.0001) as well as triglycerides (103.5 \u00b1 12.8 mg/dL vs. 175.5 \u00b1 22.8 mg/dL, p < 0.0001). In nociceptive tests, chitosan ameliorated thermal hyperalgesia (Tail-Flick: T1DM 1.25 \u00b1 0.19 s vs. T1DM+Chitosan 1.54 \u00b1 0.16 s; p = 0.0188) and mechanical allodynia (Von Frey: T1DM 0.16 \u00b1 0.07 g vs. T1DM+Chitosan 0.38 \u00b1 0.15 g, p = 0.0103). Electrodiagnostically, chitosan improved CMAP amplitude (T1DM 5.756 \u00b1 0.706 mV vs. T1DM + Chitosan 6.756 \u00b1 0.760 mV, p = 0.0409) and reduced CMAP duration (3.161 \u00b1 0.217 ms vs. 2.900 \u00b1 0.080 ms, p = 0.0273).

Recent studies have demonstrated that neuroglial vascular unit (NGVU) injury leads to distinct fundus changes in DR, including exudates, cotton-fluff spots, microangiomas, hemorrhages, and neovascularization. Currently, the primary clinical treatment options primarily target retinal microvascular degeneration during the middle and late stages of DR through techniques such as retinal laser photocoagulation, antivascular endothelial growth factor (VEGF) therapy, and vitrectomy. However, progression to these stages often results in irreversible damage to visual acuity with limited treatment efficacy. In recent years, relevant research has confirmed that NGVU injury occurs prior to retinal microangiopathy in patients with DR, and it is closely associated with impaired visual function. Therefore, targeting NGVU holds potential for future therapeutic interventions aimed at preventing and treating early-stage DR. This review identifies six key molecular targets (P2X7 receptor, NLRP3 inflammasome, retinal microglial cell necroptosis pathway, spermine oxidase, and AQP4-AS1 lncRNA) that mitigate NGVU dysfunction in preclinical models. Literature search was conducted in PubMed/Embase using keywords \"diabetic retinopathy,\" \"neuroglial vascular unit,\" and \"targeted therapy\" (2018-2024), focusing on preclinical studies with in vivo efficacy data.",

Insights Into the Role of Neurovascular Unit Cells.\nAbstract: Ischemic stroke, a leading cause of disability and mortality, initiates a complex damage cascade within the neurovascular unit (NVU), leading to blood-brain barrier (BBB) disruption and neuroinflammation that severely exacerbates secondary injury. Neuroglobin (Ngb), an endogenous protein induced by brain injury, represents a high-potential neuroprotective target. While the precise mechanisms underlying its protective action remain incompletely elucidated, substantial evidence points to its multifaceted ability to mitigate ischemic damage. To fully unlock this potential, a fundamental understanding of how neurons, astrocytes, microglia, and pericytes, coordinate their function in response to stress, and specifically identifying the role Ngb plays within this integrated cellular network, is required. This review examines the post-stroke interplay among these cells, analyzing current knowledge about how Ngb modulates the collective inflammatory response by suppressing pro-inflammatory pathways and fostering a neuroprotective environment. Furthermore, Ngb's upregulation in glial cells and pericytes promotes direct neuronal repair mechanisms, such as neurite outgrowth and axonal regeneration, while supporting neuronal survival and BBB integrity. Importantly, evidence suggests that Ngb's efficacy is most pronounced when its intracellular concentration exceeds the levels achieved through physiological upregulation. In this regard, we integrate broad preclinical evidence with specific insights from nanoparticle-mediated delivery systems that enable effective Ngb transport to NVU cells. These synthesized findings demonstrate beneficial outcomes in stroke models, driven by the modulation of mitochondrial dynamics, cytoskeletal remodeling, and synaptic regeneration pathways. Collectively, the literature indicates that targeted therapeutic Ngb may enhancement strategies effectively complement endogenous levels to orchestrate protective responses across the NVU. Nonetheless, a detailed investigation into the therapeutic utility of Ngb is still required to fully translate encouraging preclinical findings into successful clinical application for improving stroke outcomes.",

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses PRISMA 2020 (PROSPERO CRD420250653145), we searched the PubMed, Web of Science, Scopus, and Embase databases up until 20 March 2025, for parallel-group randomized controlled trials (RCTs) of oral vitamin E in adults (\u2265\u200918 years) with electrophysiologically confirmed DPN. Two independent reviewers performed screening, extraction, and the revised Cochrane Risk of Bias tool version 2.0 (RoB 2.0). Random-effects meta-analyses were conducted using the mean differences (MD) with 95% confidence intervals (CI). Five RCTs (n\u2009=\u2009660) met the criteria. Tocotrienol-rich vitamin E increased sural sensory nerve-conduction velocity (NCV) by 1.77\u00a0m s\u207b\u00b9 (0.80-2.74) and median sensory NCV by 1.53\u00a0m s\u207b\u00b9 (0.44-2.63); tibial motor NCV rose 1.47\u00a0m s\u207b\u00b9 (0.36-2.58) versus placebo. Nerve-action-potential amplitudes and glycated hemoglobin A1c (HbA\u2081c) were unchanged (MD -\u20090.06%, -\u20090.18-0.06). Adverse-event rates were similar between groups. Two trials had a low risk of bias; one presented some concerns. Vitamin E yielded selective NCV gains without amplitude change, suggesting preservation or remyelination of sensory fibers rather than axonal regeneration. The absence of glycemic effects indicates neuroprotection independent of glucose control, positioning vitamin E as a potential adjunct-not substitute-to antidiabetic therapy. Heterogeneity in isoform, dose, and treatment duration (\u2264\u200912 months) and modest sample sizes limit certainty.

Retinal inflammation and angiogenesis contribute largely to the neuronal degeneration in DIR. The current study is aiming to test the effect of oral betanin doses in protection from DIR in rats along with a network pharmacology study to investigate an assumption that betanin may inhibit nuclear factor-\u03ba B (NF-\u03baB). Three rat groups were assigned as vehicle, DIR, and DIR\u00a0+\u00a0Betanin 100\u00a0mg/kg. Molecular docking indicated the possible binding between betanin and NF-\u03baB while the bioinformatic study highlighted a relation between this possible inhibition and suppression of NOD-like receptor pyrin domain-containing protein 3/vascular endothelial growth factor (NLRP3/VEGF) axis. The rat experimental study validated this assumption and indicated a protective effect for betanin on rat retinas as shown by routine hematoxylin and eosin staining (retinal thickness and ganglion cell count) and periodic acid-Schiff staining that was mediated through mitigating expression/protein level for of NF-\u03baB, NLRP3, TNF-\u03b1, IL-6 and VEGF proteins. Immunohistochemistry showed that betanin was able to suppress retinal content of the glial fibrillary acidic protein (GFAP).

This review examines the complex structural, functional, and molecular differences in NMJs that innervate fast- and slow-twitch skeletal muscle fibers. Fast-twitch fibers, optimized for rapid and powerful contractions, possess elaborate NMJs with deep folds, high neurotransmitter turnover, and greater vulnerability to synaptic fatigue and degeneration. In contrast, slow-twitch fiber NMJs exhibit simpler but more stable architectures that support sustained, fatigue-resistant activity. These differences are not fixed but subject to activity-dependent plasticity and pathological remodeling. Chronic stimulation, injury, and aging influence NMJ morphology, with fast-twitch junctions more prone to degeneration in conditions such as ALS, myasthenia gravis, and diabetic neuropathy. Slow-twitch NMJs often resist early deterioration due to superior trophic support, metabolic stability, and more robust expression of synaptic organizers, such as agrin and PGC-1\u03b1. Several key signaling pathways, including agrin-MuSK-LRP4, Wnt/\u03b2-catenin, and neuregulin/ErbB, govern NMJ maintenance with fiber-type-specific nuances. These insights underscore the importance of tailoring therapeutic strategies to the muscle fiber phenotype. Gene therapies, neuromuscular electrical stimulation, and biomaterial scaffolds are emerging as promising modalities for preserving or restoring NMJ integrity, especially in fast-twitch fibers at higher risk of degeneration. Understanding fiber-type-specific NMJ biology enhances our understanding of motor control, muscle aging, and neuromuscular disease progression, and it opens pathways for precision therapeutics that target vulnerable synapses with structural and functional specificity. This review introduces a novel perspective by emphasizing fiber-type-specific NMJ differences and their implications for targeted therapies.",

Diabetic retinal neurodegeneration (DRN) caused by high glucose might be the earlier pathological change preceding vascular injury. Resveratrol has been showed to have therapeutic effects on DRN but the mechanism remains unclear. Ferroptosis is a new form of regulated cell death and has been found to be involved in DRN. In this study, we found genetic relationship between resveratrol and ferroptosis in DRN pathogenesis using bioinformatics analysis and demonstrated HIF-1\u03b1 and HMOX1 as the hub genes. Our study established in vitro model of DRN in high-glucose cultured SH-SY5Y cells and found ferroptosis processes characterized of reactive oxygen species (ROS) accumulation and cellular mitochondrial damage along with upregulation of HIF-1\u03b1 and HMOX1. Application of resveratrol alleviated high glucose-induced ferroptosis phenotypes in SH-SY5Y cells through inhibiting HIF-1\u03b1 and HMOX1. We also confirmed ferroptosis process and RGC damage in diabetic (db/db) mouse model. The upregulation of HIF-1\u03b1 and HMOX1 was also found in diabetic mouse retina. By resveratrol gavage, RGC damage in diabetic (db/db) mouse model was alleviated and the expression level of HIF-1\u03b1 and HMOX1 in retina was decreased.

A major therapeutic challenge is promoting RGC survival and axon regeneration. Canonical research focused on intrinsic neuronal growth capacity and the inhibitory central nervous system (CNS) environment, but overlooking the role of retinal synaptic communication. MAIN BODY: This review summarizes emerging evidence that retinal interneuron-to-RGC synaptic connections are both structurally and molecularly dysregulated following RGC axon injury. Such synaptic plasticity critically regulates RGC survival and regenerative capacity, at least partly by orchestrating intrinsic repair programs. We then address two central unresolved questions: first, what are the specific molecular pathways that alter this interneuron-to-RGC signaling after injury, and second, how do glial cells participate in this transsynaptic dysregulation. Finally, we evaluate the translational potential of these findings, including the identification of biomarkers and the development of novel neuroprotective strategies that target synaptic connections. CONCLUSION: Synaptic communication is a fundamental regulator of RGC fate after injury. Understanding synaptic dysregulation and the mechanisms involved is essential for developing new synapse-targeted strategies to monitor progression of neurodegenerative diseases and promote neural repair.",

Secondary analysis of a multicenter, double-masked, sham-controlled, randomized clinical trial. We analyzed 589 study eyes with acute NAION from 729 participants prospectively enrolled in the QRK207 trial who had separate Screening and Day 1 evaluations. Progression was evaluated at screening, Baseline, and Month 2. Only pre-treatment and placebo-group participants were included. Visual loss was modeled using best-corrected visual acuity (BCVA), defined as \u226510- or \u226515-letter loss on the Early Treatment Diabetic Retinopathy Study (ETDRS) scale, and standardized automated perimetry (SAP) using censored average total deviation (avgTD). Logistic regression, random forest, XGBoost, and support vector machine classifiers were trained with 5-fold cross-validation. Performance (AUROC, PR-AUC, accuracy, sensitivity, specificity, F1-score) and SHapley Additive exPlanations (SHAP) identified systemic and ocular predictors of visual deterioration. No features were extracted from raw OCT scans, fundus photographs, or raw visual field images; analyses were limited to structured clinical/systemic and trial-captured variables (including numeric ophthalmic measures when available). Model performance for visual function progression, and the clinical features contributing most to predicted risk. Models showed modest performance (AUROC 0.59-0.77; PR-AUC up to 0.60 varied by endpoint and prevalence). Early decline was associated with fellow-eye NAION, obstructive sleep apnea, and higher diastolic pressure, while later progression reflected metabolic and vascular stress (elevated LDH, triglycerides, blood pressure, BMI). Preserved RNFL thickness, normal renal indices, and diabetes medication use were linked to lower risk. Machine-learning models achieved modest discrimination but identified clinically relevant features distinguishing early from later NAION progression, supporting future biomarker-based and longitudinal modeling efforts. Findings suggest that improved prediction will likely require richer ophthalmic biomarkers (e.g., OCT/VF-derived features), multimodal models, and longitudinal approaches.",

Mutations in the myocilin (MYOC) gene represent one of the most common genetic factors associated with primary open-angle glaucoma (POAG). However, the mechanism underlying MYOC mutation-associated POAG is poorly understood. Here, using human disease modeling of MYOC mutation (A445V)-dependent POAG, which is usually without ocular hypertension, we have tested a hypothesis that human RGCs (hRGCs) are the target of the mutant protein, making them vulnerable to degenerative changes. Examination of hRGCs generated from MYOCA445V POAG patient-specific induced pluripotent stem cells (iPSCs) revealed that their differentiation is adversely affected, compared to those generated from isogenic control iPSCs. Retinal ganglion cells regulatory and axon growth and guidance gene expression is decreased in patient-specific hRGCs vs isogenic controls. Consequently, the former display immature neurites and their ability to form synapses with the target cells and regenerate are compromised. Furthermore, they display immature networking physiology compared to isogenic controls. The pathological burden of the mutant protein is reflected in their preferential retention in the endoplasmic reticulum (ER) of patient-specific hRGCs, activating the unfolded protein response (UPR) toward mutation-associated developmental phenotype. Furthermore, we demonstrate that REDD1, a stress-induced factor, is a mechanistic link between the MYOCA445V-activated UPR axis and inhibited mTOR signaling, a critical regulator of RGC development and function. Ours is the first demonstration of MYOC mutation-dependent hRGC phenotype and posits a mechanism for hRGC susceptibility toward degeneration independent of ocular hypertension.",

Group I mGluRs (mGluR1 and mGluR5) interact with PSD adaptor and scaffolding proteins, such as Homer, Shank, Norbin, and PICK1, as well as intracellular downstream effectors, creating a molecular network that resembles a Lego-like structure, where modular protein interactions fine-tune glutamatergic transmission. Evidence from preclinical research indicates that dysregulation of mGluR expression and function, along with disrupted PSD protein expression, may contribute to the pathophysiology of schizophrenia by altering glutamatergic neurotransmission and synaptic stability. Antipsychotic mechanisms of action may involve, at least in part, the modulation of mGluR activity mediated through PSD proteins. Notably, novel agents that enhance spinogenesis by acting at the level of PSD proteins, such as SPG302, may open promising avenues for therapeutics aimed at restoring synaptic integrity. While Group I mGluRs dominate postsynaptic regulation, Group II (mGluR2/3) and III (mGluR4/6/7/8) receptors -primarily presynaptic- inhibit neurotransmitter release and plasticity, offering complementary therapeutic avenues. Emerging strategies, such as allosteric modulators of mGluRs, aim to rebalance synaptic signaling in treatment-resistant schizophrenia. This review synthesizes how PSD proteins and mGluRs interact in schizophrenia, exploring their potential as druggable targets for novel therapies.",

DR is characterized by multidimensional pathological changes in retinal neurons, microvasculature and supportive cells, leading to an intricate damage network. It is predominantly marked by neuropathy, encompassing retinal neuronal dysfunction, aberrant activation of glial cells, and degeneration of synaptic structures. In severe instances, it can result in visual impairment and, in the worst-case scenario, blindness. As diabetes progresses, retinal nerve tissue frequently sustains damage owing to oxidative stress, inflammatory responses, and compromised mitochondrial function. Although the precise neuroprotective mechanisms remain elusive, exercise has the ability to bolster mitochondrial function in retinal cells, diminish oxidative stress, and curb inflammatory reactions, thereby safeguarding the neurophysiological function of the retina. Irisin is a myokine primarily secreted by skeletal muscles in response to exercise stimulation. Moreover, being produced in trace amounts across a variety of tissues, it has the capacity to regulate the physiological processes of multiple organs. Recent studies have indicated that irisin can exert powerful neuroprotective effects by enhancing cellular glucose uptake, improving mitochondrial function, inhibiting the expression of pro-inflammatory factors, and resisting ferroptosis. In this review, we systematically collated and synthesized existing evidence on irisin-related signaling pathways and comprehensively assessed its regulatory potential in alleviating neuroinflammation and promoting neural repair in diabetic retinopathy and offer insights into future research directions in this field.",

This cross-sectional study included 45 eyes from 28 diabetics without DR and 46 eyes from 31 controls (mean age in both groups, 59 years). Macular optical coherence tomography (OCT) scans were acquired for retinal nerve fibre layer (RNFL) and ganglion cell layer thickness measurements. Thickness measurements were obtained using the Early Treatment of Diabetic Retinopathy Study grid. Retinal mid-peripheral CFZs were computed from OCT angiography images using custom MATLAB software. Retinal function was evaluated as a pilot exploratory objective using full-field flash electroretinography. Correlations between mid-peripheral CFZs and retinal structure and function were assessed using linear mixed-effect models, accounting for the association between eyes, while receiver operating characteristic curves were used to compare the multimodal models. Larger periarteriole CFZs were associated with thinner inner inferior RNFL thickness (\u03b2\u2009=\u2009-0.48, p\u2009=\u20090.03) in diabetics without DR. Functionally, there was no significant association between the mid-peripheral CFZs and ERG parameters (p\u2009>\u20090.05) in the no DR group; these findings should be interpreted with caution given the pilot nature of the functional data. The multimodal model of vascular and structural parameters had a modestly improved area under the curve (AUC) and specificity compared to the model of vascular parameters alone (AUC\u2009=\u20090.85 versus 0.83, specificity\u2009=\u20090.65 versus 0.54, respectively). These findings demonstrate that enlarged mid-peripheral periarteriole CFZs are associated with thinner RNFL in diabetics without clinical retinopathy. The multimodal model of vascular and structural metrics showed modestly improved diagnostic ability. This study shows early novel retinal vascular and neural associations in diabetics without clinical retinopathy and demonstrates the potential utility of a multimodal model for discriminating this group from healthy controls.",

Nervonic acid (NA) is recognized for its neuroprotective and anti-inflammatory properties. However, its role in DN has not been fully elucidated. In this study, we investigated the protective effects of NA against T2DM-induced DN using a zebrafish model and explored the underlying molecular mechanisms. T2DM was induced in zebrafish larvae through a high-fat, high-glucose diet combined with a low dose of streptozotocin. Larvae were subsequently treated with NA at concentrations of 125, 250, or 500\u00a0\u03bcg/mL. Motor function, myelin integrity, neutrophil infiltration, and reactive oxygen species (ROS) levels were evaluated using fluorescence imaging and histological staining. Gene expression analysis was performed by quantitative real-time PCR. Metabolomics coupled with KEGG enrichment analysis was applied to identify NA-regulated metabolic pathways. NA significantly preserved myelin integrity, reduced neutrophil infiltration, and lowered ROS levels in DN zebrafish. Expression of myelin-related genes (mbpa and mpz) was upregulated, while pro-inflammatory cytokines were downregulated following NA treatment. Metabolomic profiling revealed that NA reversed diabetes-associated dysregulation in purine metabolism, energy metabolism, vitamin B6 pathways, and redox homeostasis. Key metabolites including guanosine monophosphate, adenosine triphosphate, pyridoxal 5'-phosphate, and L-glutathione were markedly restored toward normal levels. These findings demonstrate that NA confers robust neuroprotection in DN by alleviating inflammation and oxidative stress, preserving neuronal structure and function, and reprogramming key metabolic pathways.",

Although plasticity during development allows altered visual experience to modulate dLGN synapses and excitability, evidence for experience-dependent dLGN plasticity in adults is limited. However, glaucoma might trigger compensatory plasticity in adult dLGN, thereby compensating for diminished RGC synaptic drive. Here, we tested this theory using aged DBA/2J mice, which develop high intraocular pressure and glaucoma. In brain slice recordings, we found that diminished RGC inputs could drive robust action potential firing in dLGN relay neurons that was comparable to controls. This was accompanied by increased intrinsic excitability and decreased magnitude of sustained inhibitory currents from delta subunit-containing GABA receptors. These results implicate multiple cellular and synaptic mechanisms that support signaling despite the diminished RGC inputs in glaucoma.",

Understanding the molecular mechanisms by which ovarian hormones and E2 influence neuroprotection is essential for developing strategies to maintain brain health in women. In this study, we examined how the loss of ovarian hormones, with or without E2 treatment, affects the brain proteome and mitochondrial energy production in aged female C57BL/6J mice (36-40 wk). The mice underwent sham or ovariectomy (OVX) surgery and were fed a high-fat diet for 10 wk; 6 wk after surgery, OVX mice received either sesame oil or E2 treatment for 4 wk. Proteomic analysis of brain homogenates revealed 4,992 proteins regulated by E2, with pathway analysis showing increased signaling proteins related to synaptogenesis. OVX reduced proteins involved in synaptic function, branched-chain amino acid and ketone metabolism, the tricarboxylic acid cycle, and oxidative phosphorylation (Complexes I, IV, and V), whereas E2 restored protein expression within these pathways. Despite alterations in OxPhos proteins, basal and state 3 mitochondrial respiration remained unchanged, although notable impairments in Complex IV enzymatic activity were apparent in OVX, which were partially reversed by E2 treatment. Overall, these results indicate that E2 supports brain health by maintaining proteins crucial for synaptic integrity and metabolism, while partially offsetting the functional decline in mitochondrial bioenergetics associated with menopause.NEW & NOTEWORTHY The menopausal transition, marked by declining estrogen levels, alters cognition, neuroplasticity, and brain metabolism. Although hormone therapy benefits cognition, its molecular effects on the brain remain unclear. Using whole-brain proteomics in aged ovariectomized (OVX) mice with or without estrogen treatment, we found that OVX reduced proteins linked to synaptogenesis and mitochondrial metabolism. Estrogen reversed these declines, restoring pathways supporting neuronal signaling and energy balance, identifying estrogen-regulated proteins critical for maintaining brain health during menopause.",

The Primary Open-Angle African Ancestry Glaucoma Genetics study previously identified 46 risk loci. To pinpoint causal variants and their corresponding effector genes, we analyzed gene expression, chromatin accessibility, and conformation in two ocular cell-types: trabecular meshwork cells (hTMCs) and retinal ganglion cells derived from induced pluripotent stem cells (hiPSC-RGCs). We identified 24 candidate genes in hTMCs and 56 in hiPSC-RGCs. The ARHGEF12 gene was selected for further validation because it was nominated by local and distal promoter interactions in both cell-types and has reproducible prior evidence of its association with POAG. While its role in hTMCs is established, its function in RGCs is unclear. hiPSC-RGCs generated from a POAG donor homozygous for the risk allele showed reduced ARHGEF12 expression, altered morphology, and disrupted neuronal activity. This framework enables functional evaluation of additional POAG risk variants.",

Ischemic stress triggers a surge of reactive oxygen species (ROS) within retinal ganglion cells, leading to mitochondrial dysfunction and initiating a vicious cycle of cellular damage. Targeting the regulation of redox balance within the RIRI microenvironment to restore mitochondrial homeostasis remains a major challenge in RIRI therapy. Here, a dual ROS-responsive carbon monoxide (CO) prodrug nanoplatform (COPN) was developed. This system integrates a ROS-sensitive CO-releasing molecule, CORM401, as the active prodrug unit, which is encapsulated within a disulfide-crosslinked dendritic nanogel matrix, thereby enabling site-specific CO release under pathological oxidative conditions. Locally released CO effectively neutralizes excessive ROS, restores mitochondrial quality control, and prevents mitochondrial DNA cytosolic leakage, thereby attenuating cGAS-STING pathway activation and subsequent neuroinflammatory responses. Furthermore, COPN successfully reverses ischemia-induced immunometabolic dysregulation, restores oxidative phosphorylation capacity, and enhances cellular metabolic resilience. This study offers a promising therapeutic strategy with strong translational potential for treating oxidative retinal diseases.",
        "41951017": "ID: 41951017\nTitle: Mitochondria transplantation preserves retinal ganglion cells and promotes CNS axonal regeneration.\nAbstract: Mitochondrial dysfunction is a central driver of retinal ganglion cell (RGC) loss in glaucoma and other forms of optic neuropathies, leading to irreversible blindness. Here, we demonstrate that replenishing the mitochondrial pool through exogenous mitochondrial transplantation (\"mitotherapy\") in adult mice not only preserves neuronal survival but also promotes regenerative competence in the central nervous system (CNS). In aging or injured RGCs, we identified profound deficits in mitochondrial biogenesis, fission-fusion balance, and mitophagy. Transplantation of functional mitochondria in in vitro models of trophic deprivation and glutamate excitotoxicity restored mitochondrial homeostasis, improved energy production, reduced reactive oxygen species, enhanced RGC survival, and drove robust neurite outgrowth, with transplanted mitochondria actively trafficking to growth cones. This effect was dampened following inhibition of mitochondrial fusion, indicating a pivotal role of fusion-dependent functional integration of exogenous mitochondria. Strikingly, intravitreal delivery of mitochondria in an optic nerve crush model of adult mice enabled their integration into RGCs, improved survival and electrophysiological responses, and supported axonal regeneration across the lesion site. These findings indicate that mitochondrial transplantation strategy rescues bioenergetic failure and supports a pro-regenerative activity of neurons, highlighting the potential of mitotherapy as a transformative approach for neurodegenerative eye diseases and CNS injuries.",
        "41952895": "ID: 41952895\nTitle: Pulsed synchrony regulation of intraocular and cerebrospinal fluid pressure: a novel paradigm for glaucoma pathogenesis and treatment.\nAbstract: Glaucoma, the leading cause of irreversible blindness worldwide, is characterized by the progressive loss of retinal ganglion cells (RGCs) and their axons. While elevated intraocular pressure (IOP) is a core risk factor, the pathogenesis of normal-tension glaucoma (NTG) remains unclear, as static IOP is within the normal range. Based on circadian fluctuations of IOP and cerebrospinal fluid pressure (CSFP), and the pressure-dependent function of the ocular glymphatic system, we propose the \"dynamic trans-lamina cribrosa pressure difference (TLCPD) imbalance\" hypothesis. This hypothesis posits that optic nerve damage may stem from abnormal pulse synchrony between IOP and CSFP (phase mismatch, amplitude mismatch, or abnormal frequency) rather than static TLCPD elevation alone, pending further validation. Dynamic imbalance induces RGC injury through dual mechanisms: mechanical stress on the lamina cribrosa (collagen fiber rupture, astrocyte activation) and metabolic dysfunction (ocular glymphatic clearance impairment, toxic waste accumulation), which ultimately converge on the activation of the programmed axonal degeneration (PAD) pathway-a conserved final common effector of RGC axon loss. Phase mismatch is the core pathological pattern in NTG. In contrast, high-tension primary open-angle glaucoma (POAG) is characterized mainly by amplitude mismatch and abnormal frequency, with potential coexistence and mutual influence of these mechanisms. Verifiable clinical (24-h IOP-CSFP synchronous monitoring) and animal experiments are proposed. This hypothesis may help explain unresolved clinical phenomena, provides novel diagnostic markers (a transient peak in TLCPD) and therapeutic strategies (CSFP regulation, glymphatic function enhancement, modulation of the PAD pathway), and opens new avenues for personalized glaucoma management.",

However, the associated phenotypes and genotypes still lack proper characterization. To characterize the clinical and genetic spectrum of ACO2-related DOA and evaluate genotype-phenotype correlations. This was a retrospective case series to describe the ophthalmological examination of novel DOA cases with a heterozygous ACO2 variant. Data were collected from 13 reference centers in ophthalmology from France and Great Britain between January 2021 and September 2025. Included participants were those patients with OA and confirmed heterozygous or compound heterozygous ACO2 variants. DOA cases with a heterozygous ACO2 variant. Positive molecular diagnosis for ACO2 variants by next-generation sequencing, clinical examination including age at diagnosis, sex, best-corrected visual acuity (BCVA), retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) thickness, visual field mean deviation (MD), and fundus examination. Data for 55 patients (median [IQR] age at diagnosis for 45 patients, 24 [8-51] years; 33 male [67%]) from 37 families with ACO2 variants were compiled. Analyses were conducted on 49 patients who were strictly heterozygous or compound heterozygous with the c.220C>G benign variant. Clinical data disclosed a high variability of severity, from pauci-symptomatic up to legal blindness. Median BCVA was 0.46 logMAR (Snellen equivalent, 20/63; IQR 0.00-0.89; n\u2009=\u200945). Four patients exhibited retinal abnormalities: 3 displayed a foveopathy, and 1 had retinitis pigmentosa. There were 12 previously unreported variants (to the authors' knowledge), including the deletion of ACO2 exon 9. No correlation between BCVA and sex, age at diagnosis (Spearman \u03c1\u2009=\u2009-0.19; 95% CI, -0.45 to 0.07), or variant type (Kruskal-Wallis test P =.33) was found, but there was a correlation between BCVA and RNFL (Spearman \u03c1\u2009=\u2009-0.74; 95% CI, -0.85 to -0.54), GCL (Spearman \u03c1\u2009=\u2009-0.60; 95% CI, -0.79 to -0.30), and MD (Spearman \u03c1\u2009=\u2009-0.65; 95% CI, -0.89 to -0.31). RNFL correlated with GCL (Spearman \u03c1\u2009=\u20090.69; 95% CI, 0.42-0.87) and MD (Spearman \u03c1\u2009=\u20090.57; 95% CI, 0.14-0.85); age at diagnosis correlated with GCL (Spearman \u03c1\u2009=\u2009-0.37; 95% CI, -0.63 to -0.03). Results of this case series reveal the high clinical heterogeneity among patients with ACO2-related DOA and demonstrated that some of these patients can also exhibit retinal abnormalities. In addition, there was a deletion of an entire ACO2 exon, emphasizing the potential importance of searching for large genomic rearrangements in patients without a molecular diagnosis. These findings support further studies to explain clinical variability, as no genotype-phenotype correlation was encountered.",

This study sought to determine the effects of pelargonidin on extracellular matrix (ECM) modulation and the inhibition of transforming growth factor-\u03b2 (TGF-\u03b2) and Janus Kinase 2/Signal Transducer and Activator of Transcription 3 (JAK2/STAT3) pathway in retinal ganglion cells of streptozotocin-induced diabetic rats. Male Sprague-Dawley rats (180-200 g) were rendered diabetic by intraperitoneal administration of streptozotocin (STZ). The rats were divided into 5 groups: control, diabetic model (STZ), STZ + low dose pelargonidin (12.5 mg kg-1 per day), STZ + medium dose pelargonidin (25 mg kg-1 per day) and STZ + high dose pelargonidin (50 mg kg-1 per day). IOP was monitored using a tonometer. Whole-mount retinal immunofluorescence staining using RNA-binding protein with multiple splicing (RBPMS) was performed to assess retinal ganglion cell (RGC) density. Protein expression levels of apoptotic markers, ECM components, and TGF-\u03b2 and JAK2/STAT3 signalling pathways were evaluated by Western blotting. Pelargonidin treatment dose-dependently reduced the elevated IOP. Importantly, immunofluorescence analysis revealed a marked dose-dependent preservation of retinal ganglion cell (RGC) density: STZ-induced RGC loss was significantly reversed by pelargonidin, with the highest dose restoring RGC density to near-control or higher levels in both the central and peripheral retina. This was achieved via modulation of apoptosis-related proteins through the upregulation of Bcl-xL, Bcl-2, and downregulation of Bad, Bax and cleaved caspase-3. Furthermore, pelargonidin modulated ECM remodelling protein expression in the RGC layer. In particular, TGF-\u03b22/Smad2/3 signalling was downregulated, and the JAK2/STAT3 pathway was upregulated. By reducing IOP, preserving RGC density, modulating ECM deposition, inhibiting TGF-\u03b2 and upregulating the JAK2/STAT3 pathway, pelargonidin exerts protective effects against diabetic retinal injury. The results of this study further confirm the pharmacological potential of pelargonidin as a therapeutic agent for diabetic retinopathy.",

Traditional methods for monitoring RGCs are labor-intensive and prone to errors. To address this, we propose Light-U-Net, a lightweight and scalable deep learning model designed to segment RGCs in retinal images. The model is trained and tested on a publicly available synthetic dataset as well as a self-generated real dataset. Additionally, we introduce a local maxima algorithm for counting RGCs based on generated annotations. A comparative analysis of various cell counting methods was performed, demonstrating that Light-U-Net combined with the watershed algorithm delivers superior segmentation and counting performance. These findings highlight the potential of Light-U-Net for automating RGC segmentation and counting, reducing errors, and improving efficiency compared to traditional approaches. Light-U-Net, in combination with watershed-based counting, provides an effective tool for glaucoma detection and monitoring, making it valuable for both disease progression tracking and treatment assessment.",

Current treatments remain limited in effectively targeting and modulating this neuroinflammatory component within the retinal microenvironment. To address this, we engineered cRGD peptide-functionalized mesenchymal stem cell (MSC)-derived extracellular vesicles (cRGD-EVs) capable of actively targeting activated microglia for the localized delivery of anti-inflammatory miRNAs. After intravitreal administration, cRGD-EVs demonstrated enhanced accumulation in the retina and specific uptake by activated microglia in a rat model of retinal ischemia/reperfusion (RIR) injury. Both in vitro co-culture models and in vivo analyses confirmed the targeting efficacy and phenotypic reprogramming of microglia from a pro-inflammatory (M1) to an anti-inflammatory (M2) state. Intravitreal injection of cRGD-EVs loaded with key miRNAs (let-7c-5p, miR-21a-5p, and miR-146a-5p) significantly suppressed NF-\u03baB pathway activation and reduced the expression of downstream pro-inflammatory cytokines. Treated animals exhibited notable preservation of retinal structure, increased RGC survival, and significant recovery of visual function, as measured by electroretinography. Furthermore, in acute ocular hypertension model, cRGD-EV treatment attenuated glaucomatous neurodegeneration and improved overall retinal homeostasis. These findings highlight cRGD-EVs as a promising targeted biologic delivery system for treating neuroinflammatory components of glaucoma and potentially other retinal diseases characterized by microglial activation.",

Patients often develop other symptoms, such as deafness and neurological dysfunction. Wolfram syndrome is caused by mutations in the WFS1 gene, which encodes wolframin protein. Despite decades of intensive research, the complex mechanisms of optic neuropathy are not fully understood, and there are currently no therapies to prevent vision loss in Wolfram patients. Here, we showed that the Wfs1 knockout mice produced by the Estonian group, in which exon 8 of the Wfs1 gene was disrupted, exhibit a progressive loss of visual acuity, optic disc pallor and severe optic nerve damage. We tested the efficiency of gene therapy using AAV2 to deliver human WFS1 to retinal ganglion cells in Wfs1 knockout mice. Our results provide the first evidence that intravitreal injection of human WFS1 has significant neuroprotective effects on retinal ganglion cells and their axons and slows the loss of visual acuity. These results demonstrate that WFS1 is able to provide both functional and structural protection to retinal ganglion cells in Wfs1 knockout mice and provide important evidence for the efficacy of WFS1 as a neuroprotective treatment for Wolfram syndrome. These results demonstrate the promising effects of gene therapy for Wolfram syndrome and encourage future research aimed at conducting clinical trials in patients.",

Neuroinflammation pervades the entire course of glaucoma, and an imbalance in the intraocular immune microenvironment is critical factor underlying progression. As an extension of the central nervous system, the retina has a unique immune microenvironment. Under physiological conditions, microglia, which are primary tissue-resident immune cells, maintain homeostasis. In pathological states, the blood-retinal barrier is compromised and allows monocyte-derived macrophages (MDMs) to infiltrate the retinal tissue. We introduce the concept of \"dual immune armies, \" specifically referring to the core retinal immune population comprising microglia and MDMs. These two cell types coordinate to form an immune network, but they demonstrate significant functional heterogeneity during glaucoma pathogenesis. Microglia act as first responders and activate rapidly during the early stages of injury, monitor changes in the microenvironment in real time, and initiate the primary inflammatory response. MDMs serve as \"late-reinforcement troops\" and infiltrate extensively following blood-retinal barrier disruption, amplify the inflammatory cascade, and exacerbate optic nerve damage. Previous studies have often conflated these two cell types, leading to a lack of precise targets for immune intervention in glaucoma. Based on recent research, this study systematically compared the origins, functions, and specific marker profiles of microglia and MDMs with a focus on elucidating their synergistic roles and functional division of labor in glaucomatous optic neuropathy. Elucidating the heterogeneity of these two immune cell populations and their precisely regulated functions at different disease stages will help clarify the key mechanisms underlying the imbalance of the retinal immune microenvironment in glaucoma. It will also provide a new theoretical basis and research direction for the development of targeted immunomodulatory strategies to protect retinal ganglion cells and potentially reverse optic nerve damage.",

Reducing intraocular pressure is currently one of the most effective treatment strategies; however, it cannot completely prevent retinal ganglion cells (RGCs) death and the resulting vision loss. Traditional Chinese medicine has been widely investigated in glaucoma treatment. This study aims to determine whether geniposide can effectively inhibit retinal cell death and to explore its potential role in glaucoma therapy. Cell experiments: Retinal R28 cells were divided into a control (CTL) group, an oxygen-glucose deprivation/reoxygenation (OGD/R) group, an OGD/R+geniposide (OGD/R+ Gen) group, and an OGD/R+Gen+heat shock protein family A member 1A (Hspa1a) small interfering RNA (OGD/R+Gen+H-KD) group. Proteomics analysis was first performed to identify key molecules altered after geniposide intervention. Quantitative real-time PCR (qPCR) and Western blotting were used to detect molecular changes after geniposide and H-KD interventions. Cell viability and death were assessed using cell counting kit-8 (CCK-8) and lactate dehydrogenase (LDH) assays. Flow cytometry, reactive oxygen species (ROS) detection, and terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining were used to evaluate apoptosis. Animal experiments: SD rats were divided into a sham control (CTL) group, an acute high intraocular pressure (aHIOP) group, an aHIOP+Gen group, and an aHIOP+Gen+Hspa1a inhibitor apoptozole (aHIOP+Gen+Apo) group. Hematoxylin-eosin (HE) staining, TUNEL staining, and flash electroretinogram (fERG) were used to evaluate retinal structure, apoptosis, and functional changes. 1) Proteomics combined with qPCR and Western blotting showed that Hspa1a expression was significantly increased after geniposide treatment. 2) Compared with the OGD/R group, the OGD/R+Gen group showed increased cell viability (P<0.05), fewer dead cells (P<0.05), decreased ROS levels (P<0.001), and reduced apoptosis (P<0.05), indicating that geniposide alleviated OGD/R-induced retinal R28 cell injury and death. 3) Compared with the OGD/R+Gen group, the OGD/R+Gen+H-KD group showed decreased phosphorylated protein kinase B (Akt, p-Akt) expression (P<0.01), reduced cell viability (P<0.05), increased cell death (P<0.05), elevated ROS levels (P<0.01), and increased apoptosis (P<0.05), suggesting that Hspa1a regulates the Akt pathway and mediates the protective effect of geniposide on retinal R28 cells. 4) Compared with the CTL group, the aHIOP group showed reduced retinal thickness (P<0.01), increased apoptosis (P<0.001), and decreased fERG b-wave amplitude (P<0.001). Compared with the aHIOP group, the aHIOP+Gen group showed increased retinal thickness (P<0.05), reduced apoptosis (P<0.05), and increased fERG b-wave amplitude (P<0.05). Compared with the aHIOP+Gen group, the aHIOP+Gen+Apo group showed decreased retinal thickness (P<0.05), increased apoptosis (P<0.05), and reduced fERG b-wave amplitude (P<0.05), indicating that geniposide alleviates aHIOP-induced retinal injury through the Hspa1a pathway. Geniposide inhibits OGD/R- and aHIOP-induced retinal cell apoptosis and tissue injury through the Hspa1a-Akt pathway, providing a potential therapeutic target for glaucoma treatment. \u76ee\u7684:

Neither category describes mouse Off-transient alpha cells, which respond strongly to spatially homogeneous inputs and are suppressed by spatial structure. We identified two circuit mechanisms that together can explain this unusual spatial selectivity. First, the inhibition that controls responses of these cells is tuned to finer spatial structure than excitation, causing the balance of excitation and inhibition to depend on spatial scale. Second, the excitatory synapses onto these cells undergo strong synaptic depression, and the modulation of that depression by presynaptic inhibition amplifies responses to the transition from spatially structured to homogeneous inputs. A spatiotemporal computational model incorporating these circuit features quantitatively recapitulates the observed responses. These findings reveal how localized inhibition and short-term plasticity jointly create the distinctive spatial selectivity of Off-transient cells.",

In this study, we investigated the protective effects of norrin against hyperglycemia-induced retinal neurodegeneration and elucidated its underlying molecular mechanisms in diabetic mice. We found that retinal neurodegeneration may precede microvascular leakage in diabetic retinas. Norrin, which is expressed in the inner retina, was significantly downregulated under diabetic conditions. Intravitreal supplementation of norrin markedly attenuated hyperglycemia-induced neurodegenerative processes, leading to retinal ganglion cell (RGC) apoptosis, including oxidative stress, inflammation, and neuropathological alterations such as reactive gliosis, glutamate excitotoxicity, and synaptic dysfunction. Norrin also reduced hyperglycemia-induced microvascular leakage and RGC apoptosis by normalizing vascular endothelial growth factor (VEGF) overexpression and restoring pigment epithelium-derived factor (PEDF) levels. Notably, PEDF upregulated by norrin effectively suppressed neurodegenerative processes induced by hyperglycemia or VEGF, thereby preserving RGC function. These findings identify norrin as a critical modulator of hyperglycemia-induced retinal neurodegeneration through restoration of the VEGF-PEDF balance. Our results highlight norrin as a potential therapeutic target for early neurodegenerative changes in diabetic retinopathy.",
        "42044330": "ID: 42044330\nTitle: Hopx(+) optic nerve head-astrocytes counter neuronal stress and glaucoma damage.\nAbstract: Retinal ganglion cell (RGC) axons form the optic nerve (ON). Numerous age-related ON diseases, including glaucoma, the second most common cause of worldwide blindness, result from multiple RGC stressors. Nearly all ON astrocytes in the optic nerve head (ONH): the junctional region between the ON and the retina in young-adult rodents expresses the homeodomain only (Hopx) protein. Hopx(+) ONH astrocytes are depleted during aging. ONH primary cultures which include Hopx(+) astrocytes secrete extracellular vesicles (ONH-EVs) which selectively enhance RGC survival and neurite extension in culture, while extracellular vesicles (EVs) secreted from distal ON cultures lacking Hopx(+) astrocytes do not. ONH-EVs also enhance RGC survival in vivo in a rodent model of glaucoma. Combining rat ONH single-cell (scRNA-seq) sequencing with EV proteomic analysis, we identified ONH-Hopx(+) astrocyte secreted factors. We interrogated the online Broad institute scRNA-seq database for rat RGC gene expression in control animals and following rodent ON crush, an RGC stress model, to correlate ONH-astrocyte secreted factors with RGC gene expression changes. Following stress, RGCs upregulate the complementary pathways involving Hopx(+) astrocytic-associated factors, suggesting reciprocal communication. Using a highly selective transgenic Hopx-cre ONH knockdown strategy, we demonstrate that eliminating Hopx(+) astrocytes also results in upregulation of RGC stress responses. Our results implicate age-related loss of young ONH-astrocytes as a crucial factor in the development of age-related optic nerve diseases, and discuss replacing ONH associated factors as a paradigm shift for ON disease treatment.",

As global adoption expands and recognition of their broad metabolic benefits grows, clinical attention is shifting toward potential secondary complications, including ocular manifestations, during rapid metabolic improvement. This narrative review synthesizes evidence from randomized trials, meta-analyses, and observational studies up to 2026 to evaluate the effects of GLP-1-based therapies on various ocular outcomes. Recent meta-analyses demonstrate an overall neutral long-term risk for diabetic retinopathy (DR) and macular edema. Transient early worsening of DR occurs primarily in patients with advanced baseline disease and rapid HbA1c reductions, reflecting a metabolic transition phenomenon rather than intrinsic retinal toxicity. This interpretation is supported by 2024 cardiovascular outcome data in a non-diabetic population (e.g., Semaglutide Effects on Cardiovascular Outcomes in People with Overweight or Obesity [SELECT] trial) that showed no increased ocular risk. Observational data suggest protective associations with glaucoma via intraocular pressure-independent neuroprotection and a reduced risk of incident age-related macular degeneration, but a potential safety signal for nonarteritic anterior ischemic optic neuropathy has emerged in recent datasets. Although the absolute incidence remains low, risk with a delayed temporal pattern appears to be increased in specific cohorts. Emerging evidence also suggests potential benefits in ocular surface homeostasis and uveitis. Accordingly, following a 2025 multidisciplinary expert consensus, risk-stratified ophthalmic monitoring, rather than routine treatment avoidance, is recommended during the early metabolic transition in high-risk diabetic patients.",
        "42069589": "ID: 42069589\nTitle: Acarbose modulates microglial Pkm2 acetylation to reshape immunometabolism and preserve retinal neurons after ischemia-reperfusion.\nAbstract: Retinal ischemia-reperfusion (IR) elicits microglia-driven neuroinflammation and mitochondrial failure that led to retinal ganglion cell (RGCs) loss, yet effective disease-modifying therapies remain limited. Acarbose (ACA), an \u03b1-glucosidase inhibitor widely used for diabetes, has recently been recognized for its dual regulatory potential on immune metabolism and aging-associated neurodegeneration. Here, we demonstrate that intravitreal ACA administration attenuates retinal inflammation and improves RGCs survival following IR injury. Single-cell RNA sequencing revealed extensive inflammatory activation and metabolic reprogramming across the retina, characterized by enhanced nicotinamide adenine dinucleotide (NAD) catabolism, particularly in microglia. ACA treatment was associated with reversal of these alterations, replenished NAD levels, and restored mitochondrial integrity. Integrative proteomic and biochemical analyses identified pyruvate kinase, muscle-type 2 (Pkm2) as a candidate regulatory node affected by ACA. Intravitreal delivery of siPkm2 partially protected against IR injury, and co-administration with ACA produced an additive trend in neuroprotection. Mechanistically, ACA upregulated sirtuin 1 (Sirt1) and reduced Pkm2 acetylation at lysine 270 (K270), which was linked to pro-inflammatory microglial activation. Structure-based virtual screening further identified HY-113082, a small molecule targeting Pkm2-K270, which synergized with ACA to suppress inflammation and enhance retinal protection. Moreover, Pkm2fl/flCx3cr1-Cre mice conferred partial resistance to IR injury, but blunted the additional benefit of HY-113082 when combined with ACA, consistent with on-target engagement. Our findings support that ACA exerts retinal protection through the Sirt1-Pkm2-NAD axis, suggesting a metabolic checkpoint that integrates immune and mitochondrial regulation. This study provides mechanistic insight into ACA's dual immunometabolic and neuroprotective actions, holding promise for therapeutic insights into neuroinflammation.",

Although microRNA-144 (miR-144) has been implicated in these processes, its precise role and molecular mechanisms remain unclear. T2DM mouse models were established using a high-fat diet combined with low-dose streptozotocin, and microglia-specific miR-144 intervention was achieved in the hippocampus via bilateral injection of adeno-associated virus. Cognitive function was assessed using the novel object recognition and Morris water maze tests, while synaptic plasticity, microglial phenotype, neuroinflammation, and Tau pathology were evaluated by immunofluorescence, Western blot, Golgi staining, transmission electron microscopy, and electrophysiology. Our results showed that overexpression of miR-144 mimicked the pathological state of T2DM, leading to impaired learning and memory, neuronal dysfunction, reduced expression of synaptic proteins, and decreased dendritic spine density. Additionally, miR-144 overexpression significantly suppressed FoxO1 and AdipoR1/AdipoR2 expression while inducing microglial M1 polarization, activating downstream NLRP3-mediated neuroinflammatory responses, and increasing Tau phosphorylation. Conversely, miR-144 knockdown effectively ameliorated these pathological changes and provided neuroprotection. These findings suggest that miR-144 could serve as a promising biomarker and therapeutic target for T2DM-related cognitive impairment. This study offers novel insights into the underlying mechanisms of T2DM-related cognitive impairment and provides an experimental foundation for exploring miR-144-based intervention strategies.",
        "42092483": "ID: 42092483\nTitle: JNK inhibition suppresses microglial NLRP3 activation and oxidative stress but unexpectedly worsens pain in diabetic neuropathy: insights from a combined in vitro and in vivo pharmacological study.\nAbstract: Diabetic neuropathy (DN) is driven by neuroinflammation and oxidative stress, with c-Jun N-terminal kinase (JNK) as a key mediator; however, the effects of JNK inhibition on neuropathic pain remain unclear. Therefore, we investigated the therapeutic potential of the JNK inhibitor SP600125 in a type 2 diabetic mouse model using combined in vitro and in vivo approaches. BV2 microglia were exposed to high glucose, lipopolysaccharide, palmitic acid, or hydrogen peroxide (H2O2) with or without SP600125 (10\u00a0nM). The PPAR\u03b3 antagonist GW9662 was used for mechanistic dissection. Diabetic mice received SP600125 (15\u00a0mg/kg/day) or vehicle for 7 weeks. In vitro, SP600125 attenuated JNK phosphorylation and suppressed pro-inflammatory activation via NF-\u03baB and NLRP3 in a PPAR\u03b3-dependent manner. SP600125 reduced palmitate-induced oxidative stress but exacerbated H2O2-induced injury (p\u00a0<\u00a00.0001), revealing context-dependent redox modulation. In vivo, SP600125 reduced diabetes-induced lipid accumulation and microglial reactivity while shifting microglia to an anti-inflammatory phenotype; however, it did not alter NLRP3, ASC, IKK\u03b1, or PPAR\u03b3 expression. Despite these effects, SP600125 paradoxically worsened mechanical allodynia and thermal hyperalgesia. Together, these findings indicate that JNK inhibition provides anti-inflammatory and anti-lipid effects but paradoxically exacerbates pain, revealing a critical dissociation between neuroprotection and pain modulation in diabetic neuropathy.",
        "42103933": "ID: 42103933\nTitle: Loss of mitochondrial DNA helicase in retinal macroglia drives neovascular retinopathy.\nAbstract: Retinopathy is a common symptom in mitochondrial diseases, and a leading cause of blindness in working-age individuals, often arising as a consequence of diabetes. Here, we demonstrate that postnatal loss of the replicative helicase of mitochondrial DNA in the astrocytes and M\u00fcller glia induces neovascular retinopathy. In these retinas, the macroglia show pathological reactivation, leading to hallmark features of neovascularization with blood-retina-barrier leakage, secondary microgliosis, and complement cascade activation. Similar reactivation of astrocytes in the cerebral cortex does not compromise vascular integrity, indicating tissue-specific roles of mitochondrial metabolism in macroglia for vascular homeostasis. Three secreted angiogenic factors-Fgf2, Pgf, and Lcn2-known to contribute to diabetic retinopathy, were induced. Spike recordings of the most sensitive retinal ganglion cells revealed normal rod function and intact retinal coding. These findings highlight the critical role of glial mitochondrial metabolism in neovascular retinopathy, with important implications for therapy development for mitochondrial and common forms of vision loss.",

Hypothesis-generating data from cardiovascular outcome trials suggest that fenofibrate therapy may reduce the progression of diabetic retinopathy. To determine whether treatment with fenofibrate reduces the progression of diabetic retinopathy. We conducted a parallel-group, double-masked, placebo-controlled clinical trial of fenofibrate. A web-based algorithm allocated participants to treatment arms by minimisation. The trial was positioned within NHS Scotland's Diabetic Eye Screening Programme. Adults with diabetes and non-referable retinopathy or maculopathy (based on Diabetic Eye Screening retinal image grading) were eligible. Study treatment was mailed to participants' homes. Participants who were eligible at the screening assessment entered an active pre-randomisation run-in during which they took 145\u2005mg fenofibrate. After randomisation, participants received 145\u2005mg fenofibrate tablets or placebo. Study treatment was taken daily in those with normal renal function, or on alternate days in those with impaired renal function. The primary outcome was a composite of developing referable diabetic retinopathy or maculopathy, or requiring treatment for diabetic retinopathy or maculopathy. Incremental cost-effectiveness was assessed in terms of the primary outcome and per modelled quality-adjusted life-year gained. Data were obtained from 6-monthly interviews by research nurses and linkage to national healthcare data sets. Selected adverse events were adjudicated by study clinicians masked to treatment allocation. One thousand four hundred and eighty-four participants entered the pre-randomisation run-in, of whom 1151 were randomised. The primary outcome occurred in 131 (22.7%) of 576 participants assigned fenofibrate and 168 (29.2%) of 575 participants assigned placebo (hazard ratio 0.73; 95% confidence interval 0.58 to 0.91; p\u2005=\u20050.006) over a median of 4.0 years. Any progression of retinopathy or maculopathy, and development of macular oedema were also reduced. There was no effect on visual function, quality of life, or visual acuity. Fenofibrate use resulted in a non-significant reduction in 6-monthly health service costs (mean difference -\u00a3101, 95% confidence interval -\u00a3243 to \u00a342), leading to dominance over standard care and a high probability of cost-effectiveness. Based on modelling (assuming no difference in background healthcare costs by treatment allocation), fenofibrate led to a small increase (\u00a36) in cost for a small gain (0.02) in quality-adjusted life-years; incremental cost-effectiveness ratio \u00a3406 per quality-adjusted life-year gained. The probability of cost-effectiveness was 79-86% at thresholds of \u00a320,000-30,000 per quality-adjusted life-year gained. Early Treatment Diabetic Retinopathy Study retinopathy grading is considered the gold standard, but it is not used in large-scale retinal screening programmes; Diabetic Eye Screening grading is based on Early Treatment Diabetic Retinopathy Study but is less granular. Fenofibrate was clinically effective and cost-effective for reducing the progression of diabetic retinopathy compared with placebo among participants with early retinal changes. LENS participants will be followed for 10 years to assess the long-term effects of fenofibrate therapy. This synopsis presents independent research funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme as award number 14/49/84. Diabetes can affect the inner layer at the back of the eye, a condition called diabetic retinopathy. Many people need to see a National Health Service eye specialist or need treatment for diabetic eye disease. Each year, diabetic retinopathy leads to 1500 people being certified as blind in the United Kingdom. This makes it a leading cause of blindness in working age adults. Fenofibrate is a drug that is sometimes used to lower cholesterol. Two studies from the 2000s suggested that fenofibrate may lower the risk of diabetic eye disease getting worse. However, those results were not convincing enough to change how doctors treat their patients. We ran the Lowering Events in Non-proliferative retinopathy in Scotland study to find out if fenofibrate may be useful for treating people with diabetic eye disease. Lowering Events in Non-proliferative retinopathy in Scotland was a large clinical trial. We studied 1151 adults with early diabetic eye disease from across Scotland. Participants came to a research clinic at the start to check if they were eligible. Study treatment was sent to peoples\u2019 homes by post. Half the people in the study took fenofibrate tablets. The other half took placebo (i.e. dummy) tablets. Nobody knew which treatment they were getting. Research nurses phoned them every 6 months over the next 4 years. The study team used information from these calls and from National Health Service records to find out what happened to participants. We found that the people taking fenofibrate had a lower chance of their diabetic eye disease getting worse compared to those taking placebo. Fewer people taking fenofibrate needed to see a National Health Service specialist, have treatment for eye disease or developed swelling at the back of the eyes (called macular oedema) compared to placebo. We now have better evidence about the positive effect fenofibrate in patients with early diabetic eye disease, and the potential for savings to the National Health Service.",

Emerging evidence indicates that intestinal dysbiosis promotes DR progression via the gut-retina axis. Short-chain fatty acids serve a critical function in regulating gut microbiota, and propionate, a vital member of them, has potential translational value in DR prevention and management through the gut-retina axis. This review summarizes the impact of propionate on the retinal microenvironment by regulating gut microbiota and metabolites, focusing on its mechanisms influencing DR development, including modulating inflammation, protecting blood vessels, regulating immunity, exerting neuroprotection, and combating oxidative stress. It provides insights for devising propionate-based therapeutic strategies against DR.",

RGC vulnerability is thought to be the result of the interaction among mechanical, vascular, metabolic and neurodegenerative processes which progressively lead to RGC and optic nerve axon death. Clinical data show that glaucoma risk increases with age (A) and is higher in subjects with African-American (AA) than White-European (WE) descent. However, no quantitative mechanistic framework currently explains how A, race and ethnicity (\u03c7) interact with cellular metabolism to influence RGC vulnerability, limiting our ability to predict which individuals are at highest risk or to identify metabolic pathways to be targeted therapeutically. To fill this gap, we propose a differential model of how the concentration of RGC mitochondria (MITO) metabolism products vary with time, A and \u03c7. We represent the MITO synthase rate of adenosine triphosphate (ATP) as an exponentially decaying function of A and define the metabolic efficiency \u03b7MITO as the ratio of the stationary ATP concentration and its reference value. Simulation results indicate that \u03b7MITO decreases with A, with a maximum decrease of 37.84% and 32.4% for AA and WE subjects, respectively. Model predictions are consistent with clinical observations indicating higher glaucoma prevalence and severity in older individuals and in specific population groups, and strengthen the view of glaucoma as a multifactorial neurodegenerative disease in which metabolic vulnerability may represent one contributing pathway.",

A substantial proportion of patients experience disease progression despite adequate IOP control, which is the most significant modifiable risk factor. This indicates the involvement of additional pathogenic mechanisms. One such mechanism is neuroinflammation within the retina and optic nerve head, spearheaded by resident glial cells. These activated glial cells initiate a cascade of proinflammatory cytokines that drives oxidative stress, excitotoxic injury, and ultimately apoptosis in retinal ganglion cells (RGCs), the cells that are responsible for vision. Given the central role of cytokines in mediating this neuroinflammatory damage, several genetic association studies have checked whether functional variants in the cytokine genes modify disease susceptibility to primary glaucoma. In this review, we critically compare and assess the strength of these associations in both open-angle and angle-closure glaucoma, highlighting the inconsistencies and population-specific variability, while also evaluating the limitations of current association studies and how to overcome these challenges. Second, we address a critical mechanistic gap-how cytokine gene variants may influence glial activation, and contribute to the inflammatory ocular microenvironment that may drive disease progression. Finally, we discuss if oxidative stress-driven epigenetic modifications may modulate cytokine gene expression and amplify inflammatory responses in individuals who might be genetically predisposed to develop primary glaucoma.",

Elevated intraocular pressure (IOP), primarily due to dysfunction of the trabecular meshwork (TM), remains the most significant and only known modifiable risk factor. However, vision loss persists in some patients despite effective IOP control, highlighting the critical need to elucidate the mechanisms driving glaucomatous neurodegeneration. Emerging evidence links mitochondrial dysfunction to glaucomatous neurodegeneration, yet the precise mechanisms remain poorly defined. Here, we investigate whether defective autophagy/mitophagy, which removes damaged mitochondria, contributes to mitochondrial accumulation, oxidative stress, and neurodegeneration in glaucoma. We further explore the therapeutic potential of enhancing autophagy to improve mitochondrial turnover, mitigate RGC loss, and preserve visual function. Glucocorticoid (GC)-induced and myocilin (MYOC)-associated glaucoma mouse models were used to assess the expression of mitochondrial markers (TOM20/COX IV), oxidative DNA damage (8-OHdG), and mitophagy/autophagy-related proteins (p62, LC3, Phospho-ubiquitin (Ser65), and LAMP1) in retinal tissues. Transmission electron microscopy (TEM) was employed to analyze mitochondrial accumulation in glaucomatous ON. Mitophagy flux was assessed at early and late stages of neurodegeneration using mitophagy reporter Mt-Keima mice. The effect of RGC-specific autophagy deficiency on mitochondrial accumulation and neurodegeneration was further investigated using Atg5flox/flox mice, in which Atg5 deletion was induced by AAV2-Cre delivery. Additionally, the therapeutic effect of enhancing autophagy with Torin 2 to restore mitochondrial turnover and prevent glaucomatous neurodegeneration was evaluated in both GC-induced and myocilin-associated glaucoma models, as well as in ex vivo human retinal explants. Chronic IOP elevation led to increased mitochondrial accumulation, oxidative DNA damage, and impaired mitophagy/autophagy in glaucomatous retina. TEM analysis further confirmed the accumulation of structurally abnormal mitochondria in glaucomatous ON. In Mt-Keima mice, chronic IOP elevation significantly reduced mitophagy flux prior to RGC loss, indicating that mitophagy impairment precedes neurodegeneration. RGC-specific Atg5 deletion induced the accumulation of damaged mitochondria, leading to neurodegeneration in Atg5 flox/flox mice. Notably, pharmacological restoration of impaired autophagy with Torin 2 prevented mitochondrial accumulation and preserved the structural and functional integrity of RGCs and their axons in glaucoma mouse models and ex vivo human retinal explant cultures. Our study indicates impaired autophagy contributes to damaged mitochondrial accumulation and oxidative stress, leading to glaucomatous neurodegeneration. Enhancing autophagy in RGCs represents a promising therapeutic strategy to prevent glaucomatous neurodegeneration.",

This review synthesizes current evidence demonstrating a broad extra-hypothalamic expression of the orexin system across retinal neurons, including photoreceptors, bipolar (BCs), amacrine (ACs), and ganglion cells (GCs). We detail a sophisticated, cell-type-specific signaling framework where orexins exert complex, often antagonistic, presynaptic and postsynaptic actions via orexin 1 (OX1R) and orexin 2 (OX2R) receptors. These actions fine-tune signal transmission by potentiating glutamate release from BCs while suppressing GABAergic inhibition from ACs, ultimately modulating retinal output. A central theme emerging is the system's pivotal role in non-image-forming visual functions: OXA enhances the pupillary light reflex (PLR) by increasing the excitability of specific intrinsically photosensitive retinal ganglion cells (M2 ipRGCs), while OXB potentiates scotopic (dim-light) sensitivity by disinhibiting rod bipolar circuits. Furthermore, pharmacological inhibition of orexin receptors affects circadian rhythms in both the retina and hypothalamus. However, the field is marked by intriguing paradoxes, such as the stimulatory effects of receptor antagonists and significant species differences in OX2R expression. We critically evaluate evidence for a tonically active retinal orexin system that interfaces with dopaminergic signaling and circadian photic input. By integrating molecular, cellular, and behavioral findings, this review clarifies how retinal orexinergic modulation serves as a potential crucial interface between light detection, circadian physiology, and systemic arousal, while highlighting critical translational gaps and future research directions.",

The aims of our study are to evaluate the three-year progression of neuroretinal structure, the association between early alterations and diabetic neuropathy (DN) and the predictive role of glycaemic variability (GV) in this progression in paediatric type 1 diabetes mellitus (T1DM) subjects. Twenty-five paediatric T1DM patients, using Continuous Glucose Monitoring (CGM) and treated with continuous subcutaneous insulin infusion, without any complication, and eighteen controls (C) were enrolled and followed for three years. All subjects underwent an Optical Coherence Tomography, with analysis of neuroretinal layers. In T1DM patients, metabolic parameters, GV indexes, standardised CGM metric, peripheral and autonomic assessment were investigated. All the data were collected at baseline and every 12 months. Starting from the baseline, Retinal Nerve Fiber Layer thickness and Outer Plexiform Layer (OPL) became significantly thinner in T1DM versus C. In T1DM patients, negative correlations were observed between GV and all the inner retinal layers and positive correlations were observed between TIR and OPL. No significant correlations between HbA1c and macular layer thickness were observed. At V3, positive correlations between the retinal variation and neuropathic indexes were observed. Early morphological alterations of neuroretina are already present in paediatric T1DM patients without complications. There is a possible association between these alterations and early signs of DN. These data corroborate the hypothesis that RN is an early sign of DN and GV should be effectively addressed in the early stage of T1DM.",

Increasing evidence demonstrates that interactions among retinal glial cells exacerbate retinal inflammatory responses, which is closely associated with RGC injury. However, the detailed mechanisms governing these glial cell interactions remain largely unknown. This study aims to investigate the possible roles and the potential mechanisms of interleukin-1\u03b2 (IL-1\u03b2) in mediating the interaction between M\u00fcller cells and microglia in glaucoma. The experimental glaucoma model of chronic ocular hypertension (COH) was established in adult male mice by injection of micro-magnetic beads into the anterior chamber. Western blotting, quantitative real-time polymerase chain reaction, immunofluorescence, transwell co-culture of glial cells, RNA sequence, swept-source optical coherence tomography-based imaging and flash visually evoked potentials were employed to investigate the underlying mechanisms about the interaction of M\u00fcller cells and microglia in retina after IL-1\u03b2 stimulation, along with their impact on visual functions. We showed that in COH retinas, IL-1\u03b2 activated M\u00fcller cells and microglia, and promoted the recruitment of microglia to the ganglion cell layer. Mechanistic studies revealed that activated M\u00fcller cells released C-X-C motif chemokine ligand 1/5 (CXCL1/5) through the NF-\u03baB and p38 MAPK signaling pathways. These chemokines bond to CXC chemokine receptor 2 (CXCR2), inducing microglial activation and migration. This activation led to a significant increase in the expression of pro-inflammatory factors, which contributed to RGC death and subsequent visual function decline. Importantly, inhibition of the CXCL1/5-CXCR2 axis substantially reversed RGC loss and improved visual function. IL-1\u03b2 plays a positive feedback role in glial cell interactions, amplifying retinal inflammatory responses and impairing visual function. These findings demonstrate that inhibiting the interaction between M\u00fcller cells and microglia effectively protects RGCs, offering a promising strategic approach for glaucoma prevention and treatment.",

The time course of molecular and cellular changes induced by chronic air pollution exposure that lead to retinal pathology are unknown. In this study, we investigated the effects of moderate levels of air pollution on visual acuity and retinal phenotypes in mice using Arizona test dust (ATD) as a surrogate for ambient air pollution. Mice were exposed to aerosolized standardized test dust for three hours a day, four days a week, for up to four months in a custom-built chamber. Controls were exposed to room air. Visual function was assessed using an optomotor assay and demonstrated reduced visual acuity after one month of exposure that persisted throughout the study. Rod and cone photoreceptors also showed temporarily decreased light-evoked responses that returned to normal levels by four months. Furthermore, reduced cone photoreceptors and retinal ganglion cells were observed whereas markers of retinal stress, including Iba1-positive microglia/macrophage and GFAP expression in macroglia, were not significantly elevated. Molecular analyses indicated elevated expression of genes in the Nrf2-ARE oxidative stress response pathway. Therefore, moderate levels of aerosolized ATD caused a persistent decline in visual acuity, mild retinal degeneration and transient functional changes. This study provides new information into the pathogenesis of pollution-induced retinal damage and establishes a new mouse model for investigating detrimental effects of moderate levels of air pollution in the retina.",

While it may not always be high, intraocular pressure (IOP) is the sole risk factor that can be modified according to extensive clinical research. Glaucoma remains the leading cause of irreversible blindness, yet early treatment lowering intraocular pressure is effective in slowing the rate of visual deterioration. Issues like poor absorption, low bioavailability, and short drug resistance time have thus made the management of glaucoma challenging when using conventional ophthalmic drugs. Thus, extensive research has been conducted to explore specific nanodrug delivery systems from various nanocarriers such as nanoparticles, micelles, liposomes and nanofibers, with a focus on systems that have achieved drug release for more than 12 h. These carriers have demonstrated substantial improvements in a lot of the evaluated aspects: enhancing ocular barrier-crossing capabilities, improving bioavailability, prolonging drug release, targeting active tissues of interest, and reducing IOP. This review covers recent developments in nanocarrier ocular delivery systems regarding the management of glaucoma. In this study, the advantages and disadvantages of each system were evaluated and their potential for advancing translation from research to clinic were assessed.",

Uridine, a pyrimidine nucleoside essential for the synthesis of membrane phospholipids and neuronal metabolism, appears to be a potential neuroprotective agent, but its impact on motor behavior and peripheral nerve integrity in diabetes remains insufficiently investigated. Our study investigated the effects of chronic uridine supplementation on locomotor performance, neuromuscular electrophysiological manifestations, and morphological changes in the sciatic nerve in a murine model of streptozotocin-induced diabetes. We used male C57BL/6 mice (n = 8/group) that were assigned to three groups: sham (no diabetes), diabetic (streptozotocin-induced, diabetes mellitus, DM+), and diabetic treated with uridine (DM+U). We observed that uridine did not alter the metabolic status, as the HbA1c values remained comparable between diabetic groups (9.93 \u00b1 0.57% DM+ vs. 9.71 \u00b1 0.55% DM+U; p = 0.72), suggesting effects independent of glycemic control. The open field test revealed that diabetic mice showed a marked reduction in spontaneous locomotion, while uridine-treated mice maintained a significantly higher level of activity (longer total distance traveled 3761.7 \u00b1 789.1 cm vs. 2477.5 \u00b1 1017.6 cm in DM+; p = 0.023). Electrophysiological evaluation revealed near-normal sciatic nerve function in DM+U mice, including higher compound motor action potential (CMAP) amplitudes (10.21 \u00b1 0.64 mV vs. 5.75 \u00b1 0.72 mV; p < 0.0001) and reduced F-wave latency (6.35 \u00b1 0.45 ms vs. 7.29 \u00b1 0.31 ms; p < 0.0001). Histological and immunohistochemical analyses (PGP 9.5) further confirmed reduced nerve degeneration in DM+U mice. Our data suggest that chronic uridine administration may confer both functional and structural neuroprotection in diabetic neuropathy, even in the absence of improved glycemic control.",

This review integrates four converging lines of metabolic evidence-aqueous humor (AH) metabolomics, kynurenine pathway (KP) activity, tetrahydrobiopterin (H4BIP) biology, and NAD/one-carbon dysfunction-into a testable framework for retinal ganglion cell vulnerability. By utilizing a systematic AH metabolomics atlas covering glaucoma, pseudoexfoliation, and diabetes on a standardized HILIC-LC-HRMS platform, we demonstrate that, while aromatic amino acid elevations are non-specific markers, kynurenine monooxygenase (KMO) upregulation is a condition-specific glaucoma signature. These local findings are corroborated by systemic evidence: POAG patients exhibit significant folic acid deficiency (p = 0.007) and elevated alpha-1-antitrypsin (AAT). Critically, AAT correlates inversely with both serum folate (rs = -0.485, p < 0.001) and retinal nerve fiber layer thickness (rs = -0.386, p = 0.017), providing the first in-patient evidence linking systemic inflammation to structural optic nerve damage. We conclude that KMO serves as a critical enzymatic node linking tryptophan metabolism, H4BIP availability, and NAD synthesis. These results characterize glaucoma as a disease of progressive cofactor failure and define a research agenda for multimodal metabolic neuroprotection.",

Due to the growing evidence regarding the key role of neurodegeneration in the earliest stages of the disease and the underlying pathophysiological mechanisms, the relevance of evaluating the potential efficacy of neuroprotective therapies is emphasized. More specifically, the review addresses the current state of a promising neuroprotective approach based on the inhibition of the enzyme dipeptidyl peptidase-4 (DPP-4) using specific inhibitors administered via eyedrops, which allow direct retinal action on the neurovascular unit. The review discusses the main preclinical findings of a therapeutic strategy based on one DPP-4 inhibitor, sitagliptin, against early DRD in different experimental animal models and in vitro studies. In summary, sitagliptin eyedrops exhibit neuroprotective, anti-inflammatory, and antioxidant properties while reducing glial activation, hyperpermeability of the blood-retinal barrier, and the formation of acellular capillaries, leading to a functional improvement of the diabetic retina. However, as sitagliptin efficacy has only been evaluated at the preclinical level, clinical studies are needed to validate the translational applicability and long-term efficacy of topical administration not only of sitagliptin but also of other DPP-4 inhibitors for treating retinal diseases in which neurodegeneration plays a pathogenic role.",

In this context, single-target therapies aimed at isolated pathways have delivered only modest benefits. Lycium barbarum polysaccharides, the predominant bioactive components of goji berries, emerge as far more than simple antioxidants, functioning instead as orchestrators of interconnected signaling networks. Growing evidence shows that Lycium barbarum polysaccharides engages pathways well beyond redox control to interrupt disease-driving cascades: it limits cellular senescence through the SIRT1/p53 axis, preserves blood-retinal barrier integrity by maintaining aquaporin-4 at astrocytic endfeet, and biases microglia from proinflammatory M1 toward reparative M2 states. Beyond immunomodulation, Lycium barbarum polysaccharides promotes clearance of pathogenic protein aggregates and suppresses pathological neovascularization via the miR-15a-5p/ VEGFR2 axis. While antioxidant effects may predominate in early disease, the actions of LBP become more targeted as pathology advances, a stage-dependent selectivity that helps explain its cross-disease efficacy. In age-related macular degeneration, Lycium barbarum polysaccharides sustains metabolic homeostasis in retinal pigment epithelium by tuning autophagic flux through the miR-181/BCL-2 axis. In glaucoma, it safeguards mitochondrial membrane potential in retinal ganglion cells, supporting energy metabolism and survival. Collectively, these properties position Lycium barbarum polysaccharides as a pleiotropic regulator capable of reshaping multiple disease trajectories. Realizing its clinical potential will require precise identification of active metabolites, rigorous in vivo pharmacokinetic profiling, and rational combination with current standard-of-care therapies.",

Here, we report eight stable plasma protein targets for glaucoma, identified through a large-scale proteome-wide association study integrated with Mendelian randomization and colocalization analyses. Among these candidates, we show that the DnaJ heat shock protein family member B14 (DNAJB14) acts as a critical neuroprotective factor. Using single-cell and bulk transcriptomics, we demonstrate that Dnajb14 is characteristically expressed in retinal ganglion cells (RGCs) and that its abundance is inversely correlated with ferroptosis under ischemic stress. Furthermore, our results reveal that Dnajb14 preserve RGC survival and structural and functional integrity in multiple acute and chronic murine models. Mechanistically, Dnajb14 overexpression robustly alleviate ischemia-reperfusion-induced retinal injury, whereas targeted knockdown exacerbate lipid peroxidation, mitochondrial dysfunction, and ferroptosis. Taken together, our findings highlight that Dnajb14 is a key regulator of RGC survival through inhibition of ferroptosis, thereby making it a promising therapeutic candidate for glaucoma treatment.",

Caffeic acid (CA), a dietary polyphenol, has demonstrated antioxidant and neuroprotective effects. This study evaluated the protective role of CA under diabetic-like conditions using an in vitro glucolipotoxicity model in HT-22 hippocampal neurons exposed to high glucose and oleic acid (HG\u2009+\u2009OA). CA was administered at low (5 \u00b5M) and high (25 \u00b5M) concentrations prior to HG\u2009+\u2009OA treatment. CA significantly enhanced neuronal viability and restored the expression of neurogenesis markers (Nestin, DCX, NeuN) and synaptic proteins (PSD-95, Synaptophysin). Furthermore, CA elevated antioxidant enzyme levels (Nrf2, catalase, SOD-1), regulated apoptosis through increased Bcl-2 and decreased BAX expression, and attenuated inflammatory responses. Pyroptosis was also suppressed, as evidenced by reduced gasdermin D (GSDMD) expression. These findings suggest that CA confers multifactorial neuroprotection against glucolipotoxic injury, and may serve as a dietary modulator for mitigating diabetes-associated cognitive decline in vitro.",

Non-pathologic high myopia (HM) has been established as an independent risk factor for POAG, and the two conditions share similar structural changes in the lamina cribrosa (LC) during the early phase of optic nerve injury.

Glaucoma can be broadly classified based on the anatomy of the anterior chamber angle (open vs closed), though each group can be further subdivided by underlying etiology and chronicity. Given that chronic glaucoma is the most common type and usually progresses insidiously, periodic eye exams are critical to assess both anatomic integrity and visual function. The most important modalities for screening and monitoring at-risk patients or those with a diagnosis are ophthalmoscopy for appraising the appearance of the optic nerve head, gonioscopy for examining the anterior chamber angle, tonometry for measuring intraocular pressure, optical coherence tomography for evaluating structural damage to the optic nerve head, macula, and retinal nerve fiber layer, and perimetry for assessing visual function. Since most cases of glaucoma involve elevated intraocular pressure due to an abnormality in the drainage of aqueous humor out of the eye, current treatments, including medications, laser therapies, and surgeries, focus on lowering intraocular pressure. This chapter additionally includes a summary of significant clinical trials that have helped establish current standard practices, and concludes with an overview of promising emerging research, including stem cell therapies, gene therapies, visual prosthesis, and artificial intelligence/computer vision. Neurologists should be familiar with the diagnosis and management of glaucoma, given its similarities in pathophysiology with other neurodegenerative conditions as well as the fact that glaucoma affects both the eye and the brain.",

Extracellular magnesium (Mg2+) blocks NMDA receptors in a voltage-dependent manner, offering potential neuroprotection. However, the optimal Mg2+ concentrations and timing for effective intervention remain poorly defined. We developed a conductance-based computational model of an RGC incorporating Hodgkin-Huxley dynamics, AMPA and NMDA receptor-mediated synaptic transmission, and intracellular calcium dynamics. We systematically varied Mg2+ concentration (0.2-2.5 mM) and stimulation frequency (10-100 Hz) to identify therapeutic windows balancing neuroprotection with function preservation. At physiological frequencies (10-60 Hz), elevated Mg2+ reduced calcium (Ca2+) accumulation by 50-85% without affecting spike output. At excitotoxic frequencies (80 Hz), a narrow therapeutic window of 1.6-2.0 mM was identified, lying within a broader 1.4-2.0 mM spike-loss plateau (20% loss), where calcium additionally fell below the toxicity threshold while spike output was preserved. Intervention timing analysis revealed that Mg2+ protection efficacy is maximal with pre-treatment or immediate intervention (100%), and declines steeply with delay-reflecting the rapid early rise in Ca2+ rather than a fixed biological deadline (\u226550% protection requires intervention within 0.2 s in our abrupt-onset protocol; \u223c11% by 0.5 s). Re-analysis in terms of normalized Ca2+ progress revealed that the critical constraint for \u226550% protection is intervention before \u223c35% of peak Ca2+ accumulation-a state-based threshold reflecting relative phase sensitivity that generalizes across timescales. Sensitivity analyses confirmed robustness of the therapeutic window across physiologically plausible parameter ranges, and numerical validation demonstrated accuracy of the computational approach. These findings demonstrate that Mg2+-mediated neuroprotection is highly dependent on both concentration and timing, with implications for therapeutic strategies targeting glutamate excitotoxicity in glaucoma and retinal ischemia.",

Although there are some therapies available which primarily ameliorate the intraocular pressure (IOP), loss of sight often continues and thus illustrate the need for therapies which address the degeneration of the nervous system. Stem cell interventions have the unique potential to assist with the preservation and restoration of dysfunctional RGCs via direct cellular replacement, differential neuroprotection, and stimulating endogenous repair mechanisms. The focus of this review is on the most contemporary innovations which utilize stem cells to preserve and regenerate RGCs, which are vitally important for sight. The review addresses some of the newer cell source and cell prep technologies, particularly those using disorganized retinal microenvironment cell preps. Retinal microenvironment cell preps have resulted in some novel microenvironment cells designed to sequester stem cell grafts, to improve stem cell microenvironment cell preps, for augmenting microenvironment cell preps. Some of the major challenges such as reconstructing and integrating the lost retino-tectal and retino-collateral synapses in the visual pathway and the axonal outgrowth to and targeting appropriate central visual synaptic areas. Some major challenges are safety, RGC immunochemistry and cell type diversity, and scalable cell prep technologies. This review encapsulates how stem cell biology, along with other technologies like gene editing and tissue engineering, are forming the basis for developing first-of-its-kind regenerative therapies to restore vision in glaucoma patients, based on recent pre-clinical studies and ongoing early-phase clinical trials.",

Elevated intraocular pressure (IOP) is the only modifiable risk factor, and topical hypotensive eye drops remain the mainstay of treatment, reducing disease progression by up to 60%. However, patient adherence to therapy remains a significant challenge since this disease is usually asymptomatic in its early stages. Patient preferences and individual characteristics play a key role in adherence. This study aimed to obtain further knowledge about patient preferences regarding glaucoma treatment to better understand factors influencing adherence. A cross-sectional, multicenter survey was conducted in Spain between March and December 2024 among patients with glaucoma receiving topical treatment for more than 6 months. A questionnaire was designed to collect patients' information about their beliefs, preferences, and adherence-related factors. Of 200 participants, 169 valid responses were analyzed. Most patients were aged 51-74\u00a0years, 60.2% were women, and 71.2% had been on treatment for more than 12\u00a0months. Although 93.5% recognized the importance of preservatives, only 36.0% reported having received information about them from their ophthalmologist. Preferences between multidose bottles (MDBs, 42.2%) and single-dose units (SDUs, 37.0%) were similar, although younger women (18-30\u00a0years) showed a preference for SDUs (p\u2009<\u20090.05). Perceived ease of handling was strongly influenced by prior experience. Most patients considered SDUs as more hygienic, whereas MDBs were perceived as more environmentally friendly; nearly 79% valued ecological impact. Self-reported adherence to therapy was moderate, with 57.6% of participants denying missed doses. Nonadherent patients were more likely to favor reminder systems (74.5%, p\u2009=\u20090.029). Treatment efficacy was ranked as the most important factor, followed by side effects, ease of use, cost, and environmental impact. This study highlights substantial variability in patient preferences and underscores the importance of personalized, patient-centered glaucoma care. Enhanced education on preservatives, improved communication, and sustainable packaging could improve adherence and satisfaction. Larger multicenter studies are needed to confirm these findings and inform long-term adherence strategies.",

The loss of neurons and/or synapses has been postulated to underlie the clinical syndrome of DLB. The present study sought to elucidate the relationship between LB burden and neuronal and synaptic loss in DLB. Post-mortem brain tissue from the cingulate gyrus and inferior temporal gyrus, two regions vulnerable to LB pathology, was obtained from DLB (N\u2009=\u200920) and control cases (N\u2009=\u200920). Formalin-fixed paraffin-embedded tissue was stained to quantify LB, Alzheimer-type pathology and a neuronal marker. Frozen tissue from the contralateral hemisphere was processed for immunoblotting to compare the abundance of synaptic markers across cases. Across both regions, no evidence of reduced total neuronal density was observed, but a modest reduction in parvalbumin interneurons was observed in the cingulate gyrus, and there were only modest reductions in some synaptic markers in DLB. LB burden was markedly variable across DLB cases but was not associated with any synaptic marker abundance or neuronal density. Taken together, these findings do not support an association between LB density and neuronal or synaptic loss in DLB, even in regions with particularly high burdens of LBs, such as the cingulate gyrus. These findings suggest that the link between \u03b1Syn proteinopathy and disease requires further investigation.",

In this study, we intravitreally injected a liquid chitosan gel loaded with nerve growth factor (NGF), previously developed by our group, into the vitreous body of rats with ocular hypertension-induced glaucoma. Using a combination of techniques--including multiplex immunofluorescence staining, TUNEL staining, CTB tracing, Western blotting, visual electrophysiology, and behavioral assessments--we demonstrated that, compared with the lesion control (LC) group, the NGF-chitosan hydrogel significantly enhanced RGC survival following glaucomatous injury (by approximately 27%), preserved dendritic architecture and long-distance axonal projections, and promoted recovery of visual function. Mechanistically, treatment with the NGF-chitosan hydrogel upregulated the expression of NGF and its high-affinity receptor, tropomyosin receptor kinase A (TrkA), in the retina. In addition, it suppressed retinal glial activation and enhanced mammalian target of rapamycin (mTOR) signaling, collectively contributing to RGC protection and repair. Notably, we further observed activation of Nestin+ neural stem cells in the ciliary body region, along with their differentiation into BrdU+/Brn3a+ neuron-like cells; the precise mechanisms underlying this phenomenon warrant further investigation. In conclusion, intravitreal delivery of NGF-chitosan hydrogel provides novel mechanistic insights and represents a promising therapeutic strategy for the treatment of glaucoma.",

While one of the early symptoms of both Alzheimer's disease (AD) and DM-related ADRD is a reduction in cerebral blood flow, the underlying biological mechanisms driving this decline remain to be fully elucidated. Genome-wide association studies have linked AD/ADRD to single-nucleotide polymorphisms in the gene encoding soluble epoxide hydrolase (sEH), an enzyme we previously reported to be upregulated in the brains of an AD rat model. Our previous work also demonstrated that chronic inhibition of sEH with 1-trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl) urea (TPPU) preserves hippocampal-dependent spatial learning and memory and improves cerebral hemodynamics in both AD and DM-ADRD models. In the present study, we found that chronic TPPU treatment (1 mg/kg/day for 9 weeks) reduced brain sEH expression, improved cortical-based long-term non-spatial recognition memory involving both cortical and hippocampal networks, and reduced anxiety in DM-ADRD rats. TPPU improved brain perfusion and normalized impaired whisker-evoked functional hyperemia, an effect linked to upregulation of Kir2.1 expression in cerebral capillaries. Furthermore, TPPU restored tight junction proteins (ZO-1 and OCLN), mitigated capillary rarefaction, and suppressed astrocyte and microglial activation. At the cellular level, TPPU attenuated hippocampal neurodegeneration, restored the expression of synaptic proteins (PSD95 and SY38), and reduced levels of key pro-inflammatory chemokines, including MCP-1, RANTES, and MIP-1\u03b1, in DM-ADRD. In conclusion, TPPU preserves cognitive function in DM-ADRD by mitigating cerebrovascular dysfunction, neuroinflammation, and gliosis while protecting synaptic integrity and neuronal survival, representing a promising therapeutic strategy for DM-ADRD.",

Nuciferine, an alkaloid derived from lotus leaves, shows neuroprotective effects. This study investigated nuciferine's protective role in T2DM-induced cognitive impairment (T2DM-CI) and its mechanisms. Mouse models were created using high-fat diets and streptozotocin, along with high glucose-induced HT-22 cells. Nuciferine reduced blood glucose, improved cognitive function, and mitigated glial cell activation, neuron and synapse loss in T2DM mice. It enhanced insulin signaling by increasing protein levels of IR, IRS1, and IGF-1R, reversing PI3K and AKT phosphorylation, inhibiting GSK3\u03b2 activity, and reducing hyperphosphorylated Tau in HT-22 cells and T2DM mice. mRNA levels of these molecules matched their protein levels. Further studies revealed that nuciferine directly interacts with IR, knocking out IR abolished its effects on the PI3K/AKT pathway. Thus, nuciferine activates the PI3K/AKT pathway via IR, improving insulin resistance and slowing T2DM-CI progression.",

Literature searches of the PubMed database were last conducted in August 2025 and restricted to articles published on or after January 1, 2011. The search identified 738 articles that were reviewed in abstract form for relevancy, and 170 were selected for full-text review. After inclusion and exclusion criteria were applied, 37 articles were selected for data abstraction by panel members. A total of 20 studies were selected for inclusion, and the panel methodologist (J.A.R.) assigned each a level of evidence rating. None of these 20 articles were rated level I, 1 article was rated level II, and 19 articles were rated level III. Visual electrophysiology tests, including electroretinography (ERG) and visual evoked potentials (VEP), are objective measures that provide an assessment of visual function. Pattern electroretinography (PERG) may assist the clinician's ability to diagnose early glaucoma before visual field deficits are detected, especially in patients with retinal nerve fiber layer (RNFL) loss as measured by OCT. The photopic negative response (PhNR) of the cone-driven full-field ERG is sensitive to glaucoma damage and has a less strict requirement for lack of media opacity and steady fixation compared with PERG. Visual evoked potentials and multifocal VEP (mfVEP) can discriminate between glaucoma and control eyes, but they are technically challenging to perform, which may limit their adoption for glaucoma diagnosis. Although significant advances have been made in developing these objective visual electrophysiology tests to discriminate between glaucoma and control eyes, they are not yet recommended in routine clinical evaluation. They may have a role in select scenarios to augment currently accepted structural and functional assessments. Utility is limited because of barriers to widespread clinical implementation, including the lack of consensus on stimulation and analysis protocols with standardized reference ranges.

        "42290955": "ID: 42290955\nTitle: Regulation of NMDA receptor interactions with the actin cytoskeleton in dendritic spine development.\nAbstract: In the central nervous system, the majority of excitatory synapses exist on small actin-enriched structures protruding from dendrites, known as dendritic spines. Actin cytoskeletal rearrangements drive dynamic changes in spine shape, size, and density depending on developmental stage and synaptic activity. Spines initially emerge from the dendritic shaft as dynamic protrusions known as filipodia-like spines, which serve as precursors to mature dendritic spines. The formation and maturation of dendritic spines facilitate information transfer in neural circuits, underlying cognitive processes, such as learning and memory formation, and altered spine development results in neurodevelopmental disorders. Within dendritic spines, signaling events are regulated by many synaptic receptors such as the ionotropic N-methyl-D-aspartate (NMDA) and \u03b1-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors. However, only NMDA receptors are enriched in both immature filopodia-like spine precursors and mature dendritic spines, with AMPA receptors expressed later in development and coinciding with spine maturation. During embryonic development, most NMDA receptors contain GluN2B subunits, in contrast to mature synapses which predominantly contain GluN2A subunits. While many actin regulatory proteins, such as \u03b1-actinin-2, interact with NMDA receptor subunits, it remains unclear whether GluN2B vs. GluN2A-containing receptors exhibit differences in their preferential protein interactions that underly dendritic spine development. The following review highlights how preferential interactions between specific GluN2 isoforms and actin cytoskeletal regulators underlie synaptic development by balancing dynamic events of synaptic plasticity with competing events of synaptic strengthening and consolidation. We discuss how alterations in the expression of GluN2 isoforms and/or mutations that disrupt actin interactions contribute to neurological disorders, both developmental and degenerative.",

It is clinically characterized by progressive loss of visual field and decline in visual acuity, ultimately culminating in complete blindness. Hallmark pathological features include progressive degeneration of retinal ganglion cells and atrophy of the optic nerve. Importantly, the pathological process of glaucoma extends far beyond the eyeball, involving transsynaptic degeneration across the entire visual pathway. Microglia, as the principal immune regulators of the central nervous system, serve as the earliest sensors and effectors in the pathogenesis of glaucoma. By modulating synaptic plasticity, microglia contribute to synaptic loss and the disruption of neural circuits. They also play essential roles in maintaining neural tissue homeostasis. This review summarizes current evidence and underlying mechanisms of bidirectional transsynaptic degeneration in glaucoma. It highlights that targeting microglial functional homeostasis, particularly their regulation of synaptic plasticity, may be a promising strategy to mitigate glaucoma-associated transsynaptic degeneration and promote central neuroprotection.",

Microplastics (MPs) are omnipresent in the human food chain, yet their impact on neurodegeneration is largely unknown. Here we show that chronic oral exposure to 2-\u00b5m amine-modified polystyrene microparticles accelerates cognitive decline, amplifies A\u03b2 deposition, gliosis, and synaptic loss, and cripples autophagic flux in 5XFAD mice through the gut-brain axis. MPs accumulate in the gut, breach the epithelial barrier, and selectively expand the taurine-depleting pathobiont Bilophila, while suppressing taurine-synthesizing commensals. Untargeted metabolomics reveal a systemic taurine deficit that precedes and predicts exacerbated A\u03b2 deposition, gliosis, synaptic loss, and autophagic blockade in 5XFAD mice. Antibiotic-mediated microbiota ablation and fecal microbiota transplantation (FMT) demonstrate that the neurotoxic phenotype is fully microbiota-dependent. Restoring taurine level rebalances microglial homeostasis, reinstates autophagic flux, and rescues memory deficits in MPs-treated 5XFAD mice. Translational validation using Alzheimer's Disease Neuroimaging Initiative (ADNI) plasma shows taurine is significantly lower in AD patients versus cognitively normal controls and inversely correlates with cognitive decline. Our findings identify MPs-induced gut-microbiota dysbiosis as a modifiable environmental driver of AD pathogenesis and establish taurine supplementation as a readily translatable intervention that simultaneously fortifies the intestinal barrier and neutralizes microbiota-mediated neurodegeneration.",

While recent transcriptomic studies reveal profound glial and neuronal pathology in FTLD-GRN at the disease end stage, the mechanism that disrupts glia-neuron homeostasis remains unclear. Using induced pluripotent stem cell-derived cortical organoids, we showed that GRN-/- and GRNR493X mutations led to precocious astrogliosis that promoted neuronal stress and synaptic loss. Single-cell transcriptomics and histopathology analyses revealed a robust activation in the TGF-\u03b2 signaling pathway in GRN-/- and GRNR493X/R493X astrocytes, which was accompanied by features of immune activation, loss of synaptic support, and abundant pTDP-43+ fibrils in astroglial cytoplasm, a feature characteristic of FTLD-GRN. Intriguingly, blocking TGF-\u03b2 signaling mitigated astroglial activation and pTDP-43 proteinopathy in GRN-/- organoids. Together, these results provide insights into the cell-autonomous role of astroglial activation in neurodegeneration caused by progranulin deficiency.",

However, the impact of preoperative glycemic control on early surgical outcomes and quality of life remains to be fully elucidated. This study aimed to investigate the effects of preoperative fasting blood glucose (FBG) control on postoperative corneal recovery, visual function, and vision-related quality of life in type 2 diabetic patients undergoing phacoemulsification. In this retrospective analysis, 197 cataract patients with type 2 diabetes who underwent phacoemulsification between March 2023 and March 2025 were included. Based on their preoperative FBG levels, they were divided into a well-controlled group (FBG <6.1 mmol/L, n = 83) and a poorly controlled group (FBG \u22656.1 mmol/L, n = 114). National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25), mean corneal astigmatism, corneal edema recovery, and best corrected visual acuity (BCVA) were compared between the two groups. Postoperatively, the well-controlled group had significantly higher total scores and scores on all dimensions of the NEI-VFQ-25 scale than the poorly controlled group (all p < 0.05). Regarding corneal recovery, the group with better control showed greater changes in mean corneal astigmatism on postoperative days 7 and 30 (p < 0.001). The corneal transparency ratio was higher on postoperative day 7 (p = 0.006), while there was no significant difference between the two groups on postoperative day 30. On postoperative day 7, the logarithm of the minimum angle of resolution (logMAR) BCVA of the well-controlled group was also significantly better than that of the poorly controlled group (p < 0.001). By postoperative day 30, the differences in corneal transparency and BCVA between the two groups became non-significant (p > 0.05). Good preoperative glycemic control in diabetic patients undergoing phacoemulsification is associated with faster early corneal edema resolution, better early visual recovery, and clinically meaningful improvements in vision-related quality of life. These findings underscore the importance of enhanced perioperative glycemic management to optimize short-term surgical outcomes and health-related quality of life in this population.",

These organelles coordinate essential neuronal processes via tightly regulated crosstalk. Disruption in one organelle can propagate dysfunction across others, amplifying neurodegenerative cascades. Emerging evidence suggests that neurological diseases can result not only from disturbances in brain homeostasis but also from imbalances in gut homeostasis, highlighting the significant role of the gut-brain axis in maintaining neurological health. Helicobacter pylori, a gut pathogen contribute to the progression of neurological modalities by its secretome comprising Vac A, CagA, urease, and outer membrane vesicles via perturbing organelle function.

Sensory nerve damage impairs healing and contributes to chronic wounds, as observed in diabetic neuropathy. However, the impact of advanced wound dressings on peripheral nerves remains unexplored. Identifying dressings that favour nerve regeneration would aid in managing complex wounds. This study explores the in\u00a0vitro effects of three wound dressings on sensory neurons: a pure calcium alginate dressing (Alginate), a mixed calcium alginate combined with carboxymethylcellulose dressing and a pure carboxymethylcellulose (CMC) dressing. Sensory neurons from neural progenitors were exposed to dressing extracts for 5\u2009days. Cell viability, neurite regeneration after axotomy and neurite outgrowth from neurospheres were assessed. Neurite extension was evaluated in compartmentalised chips where extracts were restricted to the neurite compartment. Only Alginate was non-cytotoxic across tested concentrations. In the axotomy model, Alginate and CMC preserved neurite regeneration, whereas the mixed dressing impaired regeneration. In neurospheres, Alginate significantly enhanced neurite outgrowth, while CMC had no effect and the mixed dressing inhibited outgrowth. Additionally, Alginate upregulated the secretion of neurotrophic and pro-repair factors, including brain-derived neurotrophic factor and vascular endothelial growth factor, whereas CMC and the mixed dressing mostly down-regulated key factors. Finally, in compartmentalised culture, Alginate tended to enhance neurite extension, while CMC preserved it and the mixed dressing led to regression. These findings suggest that pure calcium alginate dressing supports nerve repair, essential for healing neuropathic wounds and may explain its good clinical performance in complex wounds.",

There is growing evidence that persistent activation of peripheral immune pathways, microglia and astrocytes causes progressive neurodegeneration, synaptic loss and progressive neurodegeneration. This review examines the mechanisms of microglia- driven neuroinflammatory signaling and its involvement in major neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and Huntington's disease. Key neuroinflammatory mechanisms covered in depth including microglial activation, astrocyte reactivity, peripheral immune cell infiltration, cytokine dysregulation, and blood brain barrier (BBB) disruption. This review also emphasizes the role of neuroinflammation in acute neurological symptoms and mental and cognitive impairments. Glial activation markers, inflammatory cytokines, BBB proteins and kynurenine pathway metabolites are emerging as promising biomarkers for disease diagnosis and monitoring. Additionally, the potential of new mathematical and systems level computational models to describe intricate neuroimmune interactions and forecast the course of disease and treatment results is investigated. Current and emerging therapies targeting neuroinflammation include anti-inflammatory and immunomodulatory drugs, lifestyle interventions, stem cell approaches, gene-editing technologies and nanoparticle-based drug delivery systems. Despite significant progress, translating preclinical findings into effective clinical therapies remains challenging. Future developments in integrative neuroimmune modeling, biomarker-guided therapies and precision medicine may make it possible to create individualized treatments plans targeted at reducing neuroinflammation and enhancing the course of neurodegenerative illnesses.",

Adequate oxygen and nutrient delivery are essential for maintaining tissue function and cellular survival. Over the past decades, extensive research within and beyond the field of ophthalmology has sought to elucidate the mechanisms that govern neurovascular regulation in health and disease. Growing evidence indicates that neurovascular dysfunction plays an important role in both the initiation and progression of glaucoma, a leading cause of irreversible blindness worldwide. Alterations in vascular architecture and blood flow may compromise the metabolic support required by retinal ganglion cells, increasing their vulnerability to injury and degeneration. While neurons possess limited regenerative capacity, the vascular system retains a remarkable degree of plasticity and is therefore amenable to repair. This vascular plasticity presents an opportunity to develop therapeutic strategies aimed at restoring vascular architecture and improving blood flow, complementing existing approaches focused on intraocular pressure reduction, neuroprotection, axonal regeneration, and/or neuronal transplantation. In this review, we summarize the current understanding of neurovascular function in the healthy eye, discuss mechanisms that contribute to vascular compromise in glaucoma, and highlight emerging avenues for promoting vascular regeneration and blood flow recovery. By identifying key knowledge gaps and future research priorities, we aim to outline promising directions for targeting the ocular neurovasculature to preserve retinal ganglion cell function and slow or stop progressive vision loss.",

It is emerging that neurodegeneration is not only a progressive loss of neurons, but also a nutrient-sensitive systems-level dysfunction that takes the form of redox imbalance, chronic neuroinflammation, mitochondrial dysfunction, impaired proteostasis, and synaptic loss. The aging brain are more prone to metabolic vulnerability, and subclinical deficiencies in essential nutrients and bioactive dietary compounds may exacerbate cellular stress responses that contribute to disease progression. It summarizes the existing data on the effects of nutrients like vitamins, minerals, polyunsaturated fatty acids, and various phytochemicals in modulating neuronal homeostasis by regulating oxidative signaling, inflammatory cascades, mitochondrial resilience, autophagy, and synaptic plasticity. These nutrient-mediated effects collectively influence neuronal survival, synaptic integrity, and cognitive function by affecting disease susceptibility and progression. Additionally newer metabolites of the marine and microbiome act as new neuroactive agents. The evidence from in-vitro and preclinical models, translation to clinical benefit remains inconsistent due to heterogeneity in study design, bioavailability, blood- brain barrier penetration, dosing strategies and disease stage. This review highlights emerging potential of precision nutrition frameworks that integrate nutrigenomics, metabolomics, and microbiome interactions, and individualized metabolic profiling to enable context-dependent and stage-specific interventions.

Here, we define the developmental timing, cellular distribution, and physiological role of PKM isoforms in the mouse retina. PKM2 expression begins at postnatal day 2, preceding PKM1, and is highly enriched in photoreceptors, whereas PKM1 predominates in retinal ganglion cells. Conditional deletion of PKM2 in the retina, rods, or retinal pigment epithelium (RPE) demonstrated that PKM2 is essential for maintaining retinal structure and function. Loss of PKM2 impaired glycolytic activity, decreased ATP generation, and disrupted metabolic balance, leading to cellular disorganization and degeneration in both photoreceptors and the RPE. In the RPE, PKM2 deficiency decreased RPE65 protein levels and impaired the regeneration of 11-cis-retinal, disrupting the visual cycle. PKM2 deletion disrupted the normal cone opsin gradient, indicating that PKM2-dependent metabolic and transcriptional functions are essential for maintaining proper cone organization in the retina. Moreover, rod-specific deletion of PKM2 in Abca4 mutant mice showed early signs of retinal degeneration. The studies described in this manuscript highlight the interdependence of photoreceptor and RPE metabolism and show that PKM2 plays an important role in retinal energy homeostasis and neuronal survival, providing insight into the mechanisms underlying photoreceptor and RPE degeneration in age-related macular degeneration.",

Here, we investigate Piezo2 function in the anterior visual pathway of the central nervous system with a focus on oligodendrocyte (OL) biology and myelin integrity. Using single-nucleus RNA sequencing, we identify Piezo2 expression in late differentiated OLs of the murine optic nerve, with minor expression in retinal ganglion cells. OL-specific Piezo2 deficiency results in age-dependent motor impairment and selective disruption of myelin compaction in small-caliber optic nerve axons, a fiber population known to be particularly vulnerable in demyelinating disease. Differential gene expression analysis further indicates that Piezo2 regulates myelin compaction and white matter integrity in mature OLs. Consistent with these findings, OL-encoded PIEZO2 expression is reduced in optic nerve lesion areas from multiple sclerosis patients, highlighting a convergent mechanism of small-caliber fiber vulnerability. Together, these data identify Piezo2 as an age-related regulator of OL function and myelin integrity, with potential relevance for preserving white matter structure in multiple sclerosis.",

Using a single molecule array (Simoa) method, CSF NPTX2 was measured in 688 individuals from the Sant Pau Initiative on Neurodegeneration, including Alzheimer's disease (AD), dementia with Lewy bodies (DLB), frontotemporal lobar degeneration-related disorders (FTLDrs), and cognitively unimpaired (CU) participants. NPTX2/phosphorylated-tau (p-tau)181 performance was compared to standalone NPTX2 and p-tau181. The NPTX2/p-tau ratio enhanced diagnostic performance of standalone NPTX2 and p-tau, particularly for DLB and FTLDrs (area under the curve [AUC]NPTX2/p-tau\u00a0=\u00a00.78-0.79 vs. AUCNPTX2\u00a0=\u00a00.63-0.70 and AUCp-tau\u00a0=\u00a00.59-0.75), and was more strongly associated with cognition.

Although substantial evidence links diffusion-derived metrics to underlying white matter tissue properties, the presence of complex within-voxel axonal configurations complicates their biological interpretation. Several methods have been proposed to assess diffusion properties of individual crossing axonal populations, but their validation and clinical applicability remain limited. Glaucoma, the second leading cause of blindness worldwide, is characterized by progressive loss of retinal ganglion cells and axonal damage in the optic nerve, leading to degeneration along the entire visual pathway. This degeneration includes secondary effects on fiber crossings within the optic chiasm, which are challenging to characterize with conventional diffusion methods. Here, we evaluated whether advanced diffusion metrics can detect microstructural alterations in these complex white matter configurations and whether these measures correlate with clinical markers of glaucoma severity. In this study, we evaluated 31 patients with asymmetric glaucoma and 31 healthy controls using advanced diffusion magnetic resonance imaging methods, including Diffusion Tensor Imaging, Constrained Spherical Deconvolution, multi-tensor fit via Multi-Resolution Discrete Search method, and Fixel-Based Analysis. We found significant differences of diffusion metrics in white matter tracts of the visual system, including the optic nerve, optic chiasm, optic tracts, and optic radiations. Moreover, diffusion metrics correlated with clinical ophthalmological parameters such as cup-to-disc ratio, visual field mean deviation, and retinal nerve fiber layer thickness. These findings support the use of advanced diffusion magnetic resonance imaging models as sensitive tools for detecting Wallerian degeneration and resolving complex white matter architecture in the human visual pathway, and demonstrate their utility to study other fiber-crossing regions throughout the brain.",

However, the intrinsic mechanisms through which astrocytes detect amyloid-\u03b2 (A\u03b2) pathology and develop neurotoxic properties remain inadequately understood. The dysregulation of class IIa Histone deacetylases (HDACs) has been implicated in astrocyte dysfunction under pathological conditions. This study aims to elucidate the role of HDAC7 as an astrocytic mediator of A\u03b2 that drives the formation of neurotoxic reactive astrocytes, and to propose HDAC7 as a potential therapeutic target for mitigating neuronal loss and cognitive deficits in AD. We examined HDAC7 expression in APP/PS1 mice of varying ages using RT-qPCR, Western blotting, and immunostaining analysis. Astrocyte-specific HDAC7 overexpression and knockdown were achieved\u00a0through adeno-associated virus (AAV) delivery (GfaABC1D promoter) in wild-type (WT) and APP/PS1 mice, followed by behavioral tests, immunostaining, RT-qPCR, and RNA-seq. Mechanistic studies were conducted using primary astrocytes derived from WT and\u00a0Hdac7flx/flx\u00a0mice, employing co-immunoprecipitation, Western blotting, and neuron viability assays. Pharmacological inhibition of HDAC7 in APP/PS1 mice was performed via intraperitoneal injection of TMP195, and the effects on neurotoxic reactive astrocytes, neuronal and synaptic loss, and behavioral performance were measured. HDAC7 was selectively upregulated in plaque-adjacent astrocytes in APP/PS1 mice. Overexpression of HDAC7 specifically in astrocytes was sufficient to induce a neurotoxic transcriptional profile, neuronal loss, and cognitive deficits in both WT and young APP/PS1 mice. Mechanistically, upon A\u03b2 stimulation, the upregulated HDAC7 directly interacted with and deacetylated IKK\u03b1 and IKK\u03b2, resulting in the activation of IKK, translocation of NF-\u03baB to the nucleus, and subsequent expression of neurotoxic genes. This neurotoxic conversion was dependent on IKK activity, as IKK inhibition nullified the effects in astrocytes overexpressing HDAC7. Conversely, astrocytic HDAC7 knockdown or treatment with TMP195 attenuated IKK-NF-\u03baB signaling, reduced\u00a0the presence of\u00a0neurotoxic reactive astrocytes, and rescued neurodegeneration and cognitive deficits in APP/PS1 mice. HDAC7 acts as an intrinsic effector within astrocytes, responding to A\u03b2 pathology and converting astrocytes into a neurotoxic state through direct interaction with IKK. Targeting HDAC7 presents a promising strategy for astrocyte-directed therapeutic interventions in Alzheimer's disease.",

Subsequently, the patients underwent an additional PERG a few months after the procedure. Comparative analysis focused on the PERG parameters (Mag, MagD and MagD/Mag ratio) before and after the glaucoma surgery in eyes achieving successful intraocular pressure (IOP) reduction post-operatively. The study enrolled 23 eyes from 21 consecutive patients who underwent successful glaucoma surgery between January 2021 and December 2023, each with both pre and post-operative PERG assessments. Postoperatively, there was a significant improvement of all the PERG parameters (0.97\u2009\u00b1\u20090.29 to 1.36\u2009\u00b1\u20090.29\u00a0\u03bcV, 0.55\u2009\u00b1\u20090.3 to 0.84\u2009\u00b1\u20090.42\u00a0\u03bcV, 0.52\u2009\u00b1\u20090.2 to 0.68\u2009\u00b1\u20090.25 for Mag, MagD and MagD/Mag ratio respectively, all p\u2009<\u20090.05).

A hospital-based cross-sectional observational study was conducted in Kathmandu, Nepal, from June 2020 to June 2021. GCC parameters (Average GCC, Superior GCC, and Inferior GCC) were measured using spectral-domain Optical Coherence Tomography (OCT). These parameters were compared among groups using Linear Mixed-effect Models, considering considerable inter-eye correlation. Receiver operating characteristic (ROC) curves were constructed, and area under the curve (AUC) values were calculated to assess diagnostic performance. A total of 203 patients (406 eyes) were included\u2009-\u200976 with POAG, 62 Glaucoma suspects, and 65 Controls.

A total of 94 participants with diabetes (T1D: n=49, T2D: n=45) and 94 age- and sex-matched controls underwent postural assessments using the Sensory Organization Test (SOT) and Motor Control Test (MCT). The SOT evaluated sensory system contributions (somatosensory,visual, vestibular), while the MCT assessed postural recovery responses. Both T1D and T2D groups exhibited impaired SOT performance compared to controls (P < .05). Type 1 diabetes showed impaired visual function (P < .05), while both groups demonstrated poorer postural stability in conditions requiring vestibular input (P < .05) and slower MCT response times (10 of 14 abnormal, P < .05). T2D participants relied excessively on visual input (preference function: P < .05). No significant associations were detected between DPN, body mass index, Hemoglobin A1c (HbA1c), or diabetes duration with postural control impairments. Diabetes impairs postural control, particularly in conditions that rely heavily on vestibular and visual inputs, regardless of DPN.

        "42346137": "ID: 42346137\nTitle: Neuroinflammation in Alzheimer's Disease (AD) and Glioblastoma (GBM): Shared Mechanisms and Therapeutic Insights.\nAbstract: Neuroinflammation is a key feature of both Alzheimer's disease (AD) and glioblastoma, although it leads to different outcomes in each disorder. In AD, chronic activation of microglia and astrocytes by amyloid-\u03b2 and tau contributes to neuronal injury and cognitive decline. In glioblastoma, tumor cells exploit inflammatory pathways to create an immunosuppressive microenvironment that supports tumor growth. This review compares the shared and distinct neuroinflammatory mechanisms in AD and glioblastoma and highlights their therapeutic relevance. This study was conducted as a narrative review based on a PubMed search performed by three reviewers. English-language articles on AD, glioblastoma, and neuroinflammatory pathways were included, covering original studies, reviews, meta-analyses, and experimental and clinical reports. Keywords included neuroinflammation, microglia, astrocytes, tumor-associated macrophages, inflammasomes, NLRP3, NF-\u03baB, HIF-1\u03b1, cytokines, blood-brain barrier, and miRNAs. Due to study heterogeneity, findings were synthesized descriptively. AD and glioblastoma share major neuroinflammatory mechanisms, including microglial and astrocytic activation, cytokine signaling, inflammasome activity, blood-brain barrier dysfunction, hypoxia-related changes, and miRNA regulation. In AD, these pathways promote chronic inflammation, synaptic loss, and neurodegeneration, with NLRP3, NF-\u03baB, and M1-like microglial polarization playing central roles. In glioblastoma, similar pathways are redirected toward tumor progression through tumor-associated macrophages, reactive astrocytes, angiogenesis, immune evasion, and therapy resistance. Key overlapping mediators include IL-1\u03b2, TNF-\u03b1, NF-\u03baB, HIF-1\u03b1, GSK-3\u03b2, and selected miRNAs. AD and glioblastoma are connected by common neuroinflammatory pathways, but these processes result in neurodegeneration in AD and tumor support in glioblastoma. Understanding these shared and divergent mechanisms may guide the development of biomarkers and targeted therapies focused on microglia, inflammasomes, cytokines, and immune reprogramming in both diseases.",

Methods: In this serial, cross-sectional study, 3 \u00d7 3 mm2 macular OCTA images were obtained from healthy adults and adults with diabetes mellitus (DM) with no diabetic retinopathy (DR) or with mild non-proliferative DR (NPDR). The parameters analyzed included foveal avascular zone (FAZ) area and perimeter, vessel density (VD), vessel length density (VLD), and flow index (FI) of the superficial capillary plexus (SCP) and deep capillary plexus (DCP). The associations between OCTA parameters and age were explored using multivariable linear regression models. Results: For the included 1855 patients (1855 eyes) (49% male; mean age: 55 years), the results were as follows: no diabetes (N = 217), DM no DR (N = 1352), and mild NPDR (N = 286). Increasing age was significantly associated with decreased SCP and DCP VD and VLD in the diabetic and non-diabetic groups. The slope of association between SCP and DCP FI and age in the diabetic patients was significantly different than that in the control patients. Conclusions: The strength of the association between aging and OCTA parameters differed significantly between the controls and those with early retinopathy, pointing to a potentially altered retinal vascular homeostasis secondary to diabetic pathophysiology. This finding offers insight into the early pathological biomarkers of DR and may guide early DR management for patients based on personalized risk scores.",

In this study, we propose a deep learning model that simultaneously grades DR severity and detects DME by fusing paired colour fundus and optical coherence tomography (OCT) images acquired from the same eye during the same clinical visit. Our architecture employs two parallel EfficientNet-B0 backbones pre-trained on ImageNet, one for each modality, whose 1280-dimensional feature vectors are concatenated into a 2560-dimensional joint representation. This fused representation passes through a shared fully connected block before branching into a three-class DR classification head and a binary DME detection head. We train and evaluate the model on a private dataset of 425 paired fundus and OCT eye images (850 images). The proposed architecture adopts feature-level fusion, in which modality-specific deep features are independently extracted from fundus and OCT images using separate convolutional backbones and subsequently concatenated to form a joint representation for multi-task learning. On the held-out test set (n= 85), the fusion model achieves 82.4% DR accuracy (area under the receiver operating characteristic curve [AUC] = 0.929, macro sensitivity = 0.81, macro specificity = 0.905) and 97.6% DME accuracy (AUC = 0.999, sensitivity = 0.833, specificity = 1.000). The fusion model detects 10 of 12 DME-positive eyes compared with only 7 of 12 for either the fundus-only or OCT-only baselines, representing a 43% relative improvement in DME sensitivity. Stratified five-fold cross-validation (n = 425 aggregated predictions) corroborates these findings, with the fusion model reaching 87.1% DR accuracy (AUC = 0.978) and 99.1% DME accuracy (AUC = 1.000). Gradient-weighted class activation mapping visualisations confirm that the fundus branch attends to clinically relevant macular lesions, whereas the OCT branch highlights retinal layer disruptions and subretinal fluid, providing interpretability. To the best of our knowledge, the proposed MultiRetNet is the first lightweight, task-specific multimodal architecture to jointly grade DR severity and detect DME from paired same-eye, same-visit fundus and OCT images through explicit feature-level fusion within a single end-to-end multi-task framework, distinct from recent generalist ophthalmic foundation models, supporting the value of multimodal fusion for comprehensive diabetic eye screening pending external validation.",

We have previously shown that the risk of PDR is significantly elevated in individuals with intrauterine exposure to famine. However, the genetic mechanisms mediating this association remain unknown. The aim of the current study was to investigate the molecular underpinnings of famine-related PDR by performing genome-wide association (GWAS) and interaction studies (GWIS). We analysed n\u2009=\u20092925 patients with type 2 diabetes from the DOLCE cohort of Northern Ukraine, of whom n\u2009=\u20091364 were born during historical famine periods (1929-1949, including the Holodomor and World War II). PDR cases were defined as individuals with either diagnosed proliferative retinopathy, laser-treated diabetic retinopathy (DR) or blindness in either eye. GWAS and GWIS were performed using linear mixed model (LMM) adjusted for established risk factors and genetic relationship matrix. GWAS identified rs3795299 in IL22RA1 as the top signal (pLMM\u2009=\u20091.05\u2009\u00d7\u200910-6), which was also the strongest gene in the gene-based analysis (p\u2009=\u20093.19\u2009\u00d7\u200910-5), with suggestive enrichment of response to ketones (GO) and base excision repair (KEGG) pathways. In the GWIS, the strongest signal was rs1506783 in PAPPA2 (pLMM\u2009=\u20091.29\u2009\u00d7\u200910-7). A second biologically credible candidate was rs2230805 in ABCA1 (pLMM\u2009=\u20094.44\u2009\u00d7\u200910-6), reaching borderline genome-wide significance in gene-based analysis (p\u2009=\u20094.31\u2009\u00d7\u200910-6). Interaction analyses showed suggestive enrichment for nucleosomal DNA binding (GO), tryptophan metabolism and glycerolipid metabolism (KEGG) pathways. Furthermore, at nominal significance, we validated variants in previously reported diabetic retinopathy-associated genes, including TCF7L2, SLC2A1, SLC2A11 and VDR in the GWAS, as well as 13 variants in genes including VEGF, VEGFR1, ANGPT1, PLXDC2, SELP and PON2 in the GWIS. Our findings suggest that famine-related PDR susceptibility involves distinct developmental programming mechanisms, including altered insulin-growth signalling (PAPPA2) and lipid metabolism (ABCA1), whereas immune-related pathways (IL22RA1) may contribute to the conventional glycaemia-driven route to PDR through VEGF-mediated angiogenesis. These genes represent potential therapeutic targets and emphasize the importance of the perinatal environment in lifelong vascular health and disease.",

Although elevated intraocular pressure remains the most important modifiable risk factor, increasing evidence suggests that immune dysregulation and autoimmune responses also contribute substantially to disease onset and progression. Clinical studies across different glaucoma subtypes have identified subtype-dependent immune abnormalities, including altered serum autoantibody profiles, dysregulated cytokine and chemokine expression, and changes in peripheral immune cell subsets. Experimental and translational studies further indicate that multiple immunopathogenic mechanisms are involved in glaucomatous neurodegeneration, including glial cell-mediated immune responses, activation of pattern recognition receptor signalling pathways, adaptive immune responses, and complement cascade dysregulation. These processes may interact to sustain chronic neuroinflammation, promote retinal ganglion cell injury, and accelerate optic nerve degeneration. Importantly, a better understanding of immune involvement in glaucoma has generated growing interest in immunomodulatory therapy as a potential strategy beyond intraocular pressure lowering. Targeting microglial activation, inflammatory signalling pathways, adaptive immune imbalance, and complement-mediated injury has shown neuroprotective potential in animal or in vitro models, whereas clinical evidence in glaucoma patients remains limited. These findings may provide preliminary directions for future therapeutic development. In this review, we summarise the current clinical evidence linking glaucoma with autoimmunity, discuss the major immune mechanisms implicated in disease pathogenesis, and highlight recent advances in immunomodulatory therapeutic strategies. Elucidating the immune basis of glaucoma may help pave the way for more precise and effective treatments for this complex optic neuropathy. We believe that immune dysregulation in glaucoma functions as a context-dependent amplifier of retinal ganglion cell injury rather than a uniform primary driver, with innate (microglia/astrocytes), adaptive (T/B cells, HSP-specific immunity), and complement pathways interacting to sustain neuroinflammation and neurodegeneration. This integrated immune response contributes to subtype- and stage-specific vulnerability, and targeting these maladaptive immune mechanisms represents a promising, precision-guided strategy for neuroprotection beyond intraocular pressure lowering.",

While elevated intraocular pressure (IOP) remains the primary modifiable risk factor, a certain proportion of patients continue to deteriorate despite adequate IOP control, pointing to IOP-independent mechanisms of neurodegeneration. Oxidative stress-defined as an imbalance between the production of reactive oxygen species and the capacity of endogenous antioxidant defenses-has emerged as a central, multi-tiered contributor to glaucoma pathogenesis. In the anterior segment, chronic oxidative damage to the trabecular meshwork impairs aqueous humor outflow and drives IOP elevation. In addition, oxidative stress may impair ocular biomechanical integrity, including corneal hysteresis and lamina cribrosa, resulting in heightened susceptibility to IOP fluctuations. In the posterior segment, oxidative stress directly contributes to mitochondrial damage and vascular endothelial injury, leading to RGC apoptosis. The nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein 1 (Keap1) pathway coordinates the principal endogenous antioxidant response, while nicotinamide adenine dinucleotide (NAD+) depletion links redox imbalance to metabolic vulnerability of RGCs. This narrative review synthesizes evidence published up to March 2026 on the molecular mechanisms of oxidative stress in glaucoma, the role of biomarkers in aqueous humor and systemic circulation, and the translational landscape of antioxidant-based neuroprotection-including nicotinamide, coenzyme Q10, alpha-lipoic acid, and Nrf2-activating compounds.

Within the RNVU, calcium ions coordinate neurotransmission, glial activation, vascular tone, and blood-retinal barrier maintenance, and calcium dysregulation is emerging as a unifying pathogenic hub across these conditions. Although upstream triggers differ, including mechanical stress in glaucoma, hyperglycemia in DR, oxidative damage in AMD, ischemic energy failure in RIR, and amyloid-\u03b2-driven endoplasmic reticulum stress in AD, all converge on disruption of intracellular calcium homeostasis, producing shared downstream consequences including excitotoxic injury of retinal ganglion cells (RGCs), M\u00fcller cell reactive gliosis, and pericyte hypercontraction. Broad-spectrum calcium channel blockade has shown limited clinical success, underscoring the need for cell-type-specific and pathway-selective approaches. This review therefore catalogs key interventional nodes, including transient receptor potential (TRP) channel antagonists, T-type calcium channel inhibitors, calcium/calmodulin-dependent protein kinase II (CaMKII) suppressors, and mitochondrial permeability transition pore (mPTP) inhibitors, and discusses how precision targeting of these pathways may restore RNVU homeostasis and open a therapeutic window into central nervous system (CNS) degenerative disorders.",

This study investigated whether L-serine supplementation could attenuate DN through dose-dependent metabolic and neuroprotective mechanisms in a high-fat diet (HFD) plus streptozotocin (STZ)-induced diabetic rat model. Male Wistar rats (n = 8 per group) were allocated to five groups: normal control (NC), diabetic control (DC), pioglitazone (PIO; 1.5 mg/kg/day), low-dose L-serine (S1; 200 mg/kg/day), and high-dose L-serine (S2; 400 mg/kg/day). After 60 days of oral gavage, behavioural testing, glucose and insulin profiling, HOMA-IR calculation, brain histopathology, nerve growth factor (NGF) immunohistochemistry, and LC-MS/MS-based proteomic analysis of cerebral tissue were performed. Diabetic rats exhibited marked hyperglycaemia (355.33 \u00b1 4.72 mg/dL), hyperinsulinaemia, severe insulin resistance (HOMA-IR 16.8 \u00b1 3.2; a 14-fold increase), impaired thermal nociception, motor dysfunction, and pronounced neuronal degeneration. L-serine supplementation significantly improved metabolic status: S1 reduced HOMA-IR by 77.4% and S2 by 87.5% relative to diabetic controls (p < 0.001). High-dose L-serine produced greater improvements in thermal sensitivity, motor coordination (rotarod latency 26.67 \u00b1 1.52 s vs. 16.1 \u00b1 0.85 s in DC; p < 0.05), and NGF expression (8.6-fold increase vs. DC). Histopathology confirmed attenuation of neuronal injury and gliosis in both treatment groups. Exploratory, group-level proteomic profiling identified dose-specific molecular signatures: S1 was predominantly associated with carbohydrate, lipid, and biosynthetic pathways, whereas S2 was associated with synaptic, neurotransmission-related, and proteostasis pathways. Within the constraints of an exploratory design-group-level pooled proteomics, analysis of cerebral rather than peripheral-nerve tissue, and only two doses-these findings indicate that L-serine attenuates the metabolic and behavioural features of experimental diabetic neuropathy and generates the testable hypothesis of dose-dependent neuro-metabolic remodelling. The proteomic signatures are hypothesis-generating and require orthogonal validation before any mechanistic or translational inference can be drawn.",

Therefore, neuroprotection has emerged as a promising therapeutic strategy to prevent disease progression. Topical administration via eyedrops represents a non-invasive approach to deliver neuroprotective agents directly to the retina. This review summarizes the current advances in the field of neuroprotective therapies against early DRD with a special focus on topical delivery, including preclinical and clinical evidence, while discussing the relevance of the transscleral route of absorption in all of them. In this review, the most promising neuroprotective compounds under development will be discussed, highlighting the opportunity that they represent for treating early stages of DRD.",

Indole diterpenoids (IDTs) represent a structurally unique class of fungal metabolites. Beyond their established roles as mycotoxins, these compounds have recently shown promise for neuroprotective effects. The objective of this study was to isolate and characterize novel IDTs from Tolypocladium album DWS131 and evaluate their neuroprotective activities and underlying mechanisms. Methods: IDTs were isolated through comprehensive chromatographic techniques. Their structures were elucidated using HRESIMS data, 1D/2D NMR spectra, and quantum chemical calculations. Neuroprotective effects were evaluated using glutamate (Glu)-induced R28 cells in vitro and N-methyl-D-aspartic acid-induced mouse models in vivo. A total of 48 mice were utilized for in vivo evaluations, divided into two separate experimental cohorts. In each cohort, mice were randomly assigned to four groups (n = 6 per group). Post-intravitreal injection, retinal survival and visual function were assessed via Brn3a-stained flat-mounts, H&E staining, f-VEP, f-ERG, and OptoDrum. Mechanisms involving the SLC7A11/GPX4/ACSL4 axis were investigated by Western blotting and immunofluorescence. Results: Seven previously undescribed paxilline-type IDTs, tolypindoles A-G (1-7), and two known analogues (8-9) were identified. Compounds 8 and 9 exhibited significant neuroprotection closely associated with the attenuation of oxidative stress and the modulation of ferroptosis-related pathways in Glu-induced R28 cells. In vivo, they preserved retinal ganglion cells, maintained retinal structure, and protected visual function, with compound 8 demonstrating superior efficacy. Mechanistic investigations revealed that both compounds modulate the SLC7A11/GPX4/ACSL4 signaling axis. Conclusions: This study expands the chemical diversity of T. album DWS131. Compounds 8 and 9, characterized by isopentenyl moieties, highlight a promising therapeutic potential for retinal neurodegenerative diseases such as glaucoma.",

While peripheral neuropathy is a common comorbidity, whether sensory dysfunction contributes to uncontrolled inflammation in diabetes is poorly understood. Here, within diabetic bone defects, we show that diminished sensory innervation is coupled with disrupted immune dynamics, characterized by both delayed neutrophil chemotaxis and abnormal neutrophil retention that resulted from impaired macrophage efferocytosis. Therefore, we design a chocolate chip cookie-like scaffold, in which the surface-embedded microspheres function as \"chips\" enabling burst interleukin-8 (IL-8) release, while the surrounding matrix provides sustained nerve growth factor release from silk fibroin matrix. Timely neutrophil chemotaxis induced by IL-8 triggers bone healing via stem cell recruitment, which is reinforced by sensory innervation by inducing neutrophil N2 polarization. Notably, macrophages preferentially established intimate physical proximity to outgrowing neurites to form a synapse-like structure, where they restore efferocytosis driven by neuronal Galectin-3. Moreover, spatiotemporally regulating neuroimmune circuit enhances mandibular bone regeneration in diabetic rats, highlighting the therapeutic potential of neuroimmune interaction in programming diabetic inflammation resolution.",

It arises owing to various factors, including traumatic nerve injury, neuropathic pain due to cancer, and diabetic neuropathy. Although conventional two-dimensional culture-based mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) demonstrate therapeutic potential for neuropathy, their regenerative efficacy and consistency are limited. Therefore, the present study proposes a nanobiology-based therapeutic strategy for neuroregenerative medicine. In this study, MSCs were preconditioned using transforming growth factor beta-3 and cultured in a three-dimensional dynamic culture system to produce highly functional mechanochemically primed regenerative EVs (MCR-EVs). In an ex vivo organotypic spinal cord slice injury model with demyelination, MCR-EVs were internalized by slice-resident cells and significantly attenuated cell death compared to conventional 2D-EVs (Con-EVs). MCR-EVs also promoted the recovery of axonal integrity and pro-survival signaling in injured spinal cord slices, as indicated by increased neurofilament-M immunoreactivity, restored protein kinase B phosphorylation, and growth-associated protein 43 expression. MCR-EVs exhibited enhanced therapeutic effects compared with Con-EVs in a mouse model of peripheral neuropathy induced by chronic constriction injury. The MCR-EV-treated group exhibited downregulated expression of proinflammatory genes, including tumor necrosis factor-\u03b1, interleukin-1\u03b2, interleukin-6, and cyclooxygenase-2, accompanied by inhibition of microglial activation and cell death. Additionally, the axonal structure was restored, as demonstrated by increased expression of neurofilament heavy chain, neuron-specific class III \u03b2-tubulin, and neuronal nitric oxide synthase. The MCR-EV-treated group also exhibited increased expression of Schwann cell-related markers (S100\u03b2, myelin basic protein, and myelin-associated glycoprotein), maintenance of neuromuscular structure, and upregulated platelet endothelial cell adhesion molecule 1 expression levels. Moreover, in MCR-EVs, small RNA sequencing confirmed the presence of several miRNAs that are potentially associated with nerve regeneration, inflammation, and pain modulation. These results suggest that MCR-EVs contribute to the recovery of myelinated axons and regeneration of peripheral tissues, thus protecting endothelial cell components. MCR-EVs improved therapeutic outcomes compared to current Con-EV treatments and may promote peripheral neuropathic recovery by modulating anti-inflammatory and nerve regeneration pathways.",

Eighty three glaucoma and 34 healthy participants underwent widefield OCT scans, segmented to generate ganglion cell-inner plexiform layer measurements, and 24-2 VF assessment using GII, GIII, and GV in full threshold mode. Accuracy was assessed using mean weighted absolute error and 95% prediction interval width from mixed effects models between ganglion cells per stimulus area estimated from ganglion cell-inner plexiform layer thicknesses and VF thresholds compared using mixed effects models and post hoc analyses of estimated marginal means. Across healthy and glaucoma eyes, mean weighted absolute error and 95% prediction interval widths were smallest with GV (p\u00a0<\u00a00.0001), suggesting the least model variability with GV. With VF locations in glaucoma cohort subclassified into VF nondefective and VF defective, although significant differences in mean weighted absolute error and 95% prediction interval widths were noted within stimulus sizes (p\u00a0<\u00a00.0001), larger values indicating poorer model accuracy were noted in glaucoma VF defective locations relative to both healthy and VF nondefective models. Larger mean weighted absolute errors and 95% prediction interval widths were observed with increasing disease stage in VF defective locations across all stimulus sizes (p\u00a0<\u00a00.0001). Overall, structure-function models in healthy eyes and VF nondefective locations were similar across all stimulus sizes, but larger deviations were observed in VF defective locations and with worsening glaucoma stage. Our findings suggest that GIII sufficiently balances measurement variability and VF defect detection, but that disease stage-specific variations in the structure-function relationship exist and the ability to monitor VF defect progression over time is poor regardless of stimulus size.",
        "42365203": "ID: 42365203\nTitle: Neuroinflammation in glaucoma: a myriad of cellular pathways and players.\nAbstract: Glaucoma is a complex neurodegenerative disease with multiple subtypes, yet all are characterized by the progressive dysfunction and loss of retinal ganglion cells (RGCs), which ultimately results in vision impairment and blindness. Elevated intraocular pressure (IOP) is a major risk factor for glaucoma; however, it is neither necessary nor sufficient for glaucomatous neurodegeneration, as patients can exhibit high IOP without developing glaucoma and patients can develop glaucoma with normal IOP. Yet FDA-approved treatment options are largely limited to approaches to minimize risk and reduce IOP. Thus, there is a critical need to target other aspects of glaucoma pathophysiology. Neuroinflammation is broadly defined here as immune-relevant responses, often involving microglia and astrocytes, within the central nervous system which may include peripheral immune cell infiltration. Burgeoning evidence has implicated glia in the development and progression of glaucoma in human tissues and mouse models. Most mouse models of glaucoma to date have shown that microglia and astrocytes are reactive in early stages of glaucomatous neurodegeneration prior to overt RGC loss. However, there is growing evidence that human and mouse glia adopt distinct phenotypes in response to neurodegeneration. Thus, there is critical need to expand our studies to include the new generations of human cell culture models. In this review, we discuss: 1) the evidence of neuroinflammatory processes in human glaucoma; 2) models of glaucoma relevant neuroinflammation; and the evidence specifically for 3) innate immune cell-driven and 4) macroglia-driven processes.",

Whether this expansion represents a coherent transition toward smart, manufacturable, and function-oriented tissue-engineering systems remains unclear. We conducted an AI-assisted, rule-guided, and manually audited evidence architecture reconstruction of glaucoma-related biomaterial studies published from 2006 to 2025. Records from Web of Science Core Collection, Scopus, and PubMed were integrated, deduplicated, parsed from RIS files, screened, and quality controlled. Retained studies were classified by application scenario, evidence level, and translational features. Core evidence records were assigned to five operational levels, from material preparation and physicochemical characterization to disease-microenvironment intervention, long-term functional integration, and clinical or advanced translational evidence. Theme maturity and the convergence of smart material, additive manufacturing, and tissue-engineering relevance were further assessed. From 1,227 parsed records, 596 were retained, including 547 core evidence studies and 49 review or background records. In the core evidence set, Level 1 to Level 5 evidence included 93, 57, 140, 99, and 158 records, respectively. Level 1-3 evidence accounted for 53.0% of the core evidence set, whereas Level 4-5 evidence accounted for 47.0%, indicating a substantial but unevenly distributed translational component. In situ hydrogels and contact lens-based delivery systems represented the largest application categories, whereas retinal ganglion cell protection, trabecular meshwork modeling, anti-fibrosis after glaucoma surgery, GDD/MIGS-related interfaces, and 3D printing represented smaller but more disease-specific or integration-oriented domains. Glaucoma-related biomaterials are moving beyond passive delivery platforms, but their transition toward smart materials, additive manufacturing, and functional tissue engineering remains uneven. Future studies should emphasize reproducible material design, disease-relevant functional endpoints, outflow-pathway models, neuroprotection, and engineered surgical interfaces.",

A rat DR model was established and treated with BBR, and histological analyses, including hematoxylin and eosin staining, Nissl staining, and immunofluorescence, were executed to evaluate tissue changes. Core target genes were identified using the GeneCards database, Venn diagram analysis, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment, protein-protein interaction networks, and molecular docking. Validation of key genes was performed via reverse transcription-quantitative polymerase chain reaction (RT-qPCR), Western blot, and RNA interference. BBR improved retinal morphology, reduced edema, and restored the arrangement of retinal ganglion cells in DR rats. BBR significantly reduced the levels of pyroptosis markers such as IL-1\u03b2 and IL-18, which were elevated in DR. Network pharmacology identified 10 hub genes, with six genes (JUN, STAT3, AKT1, TP53, IL-1B, EGFR) further analyzed. BBR reversed DR-induced upregulation of JUN, STAT3, and AKT1 at both the mRNA and protein levels, as confirmed by RT-qPCR and Western blot. Silencing these genes enhanced cell viability and amplified BBR's protective effects. Altogether, BBR alleviates retinal inflammation and pyroptosis in diabetic retinal ganglion cells by targeting JUN, STAT3, and AKT1, providing insights into its therapeutic potential for DR.",

In a 20-week, multicentre, open-label extension study at 15 sites in India, safety and efficacy were assessed in 52 participants who received three doses (2\u2009mg intravitreal) of MYL-1701P either continuing on MYL-1701P (continuation arm) or switching to it from reference aflibercept (switch arm). The primary outcome was safety, assessed by the incidence of treatment-emergent adverse events (TEAEs). The secondary outcome was efficacy and included change in visual acuity (best corrected visual acuity (BCVA) based on Early Treatment Diabetic Retinopathy Study (ETDRS) letters) and central subfield thickness ((CST); by spectral-domain optical coherence tomography).

We aim to assess the neuroprotective efficacy of EGb for retinal disorders and to clarify its potential mechanisms of action through a systematic review. We searched original literature about laboratory experiments from four databases which were released until April 2024. The methodological quality of included in vivo studies was assessed using the SYRCLE risk of bias tool. The results showed that out of the 398 studies initially collected, 26 articles met the requirements for full-text review. 20 of them presented in vivo data, 2 detailed both in vitro and in vivo evidence, and 4 were in vitro experiments. Results demonstrated the protective effects of EGb against several retinal disorders, including retinal ganglion cell injury, retinal degeneration, ischemia, vitreo- or pre-retinal proliferative disorder, uveitis, and diabetic retinopathy. Based on SYRCLE's evaluation of bias risk, the in vivo studies' quality scores varied from 4 to 7 points. The data indicated that EGb preserved visual function by maintaining retinal morphology and structure in preclinical models. Its action mechanism may be associated with suppressing apoptosis, attenuating oxidative stress, reducing inflammation, inhibiting angiogenesis, and suppressing proteolysis. These preclinical findings suggest that EGb may be a promising neuroprotective agent for retinal disorders. However, the methodological limitations of the included studies necessitate cautious interpretation; to demonstrate the effectiveness and safety of EGb, more extensive clinical randomized controlled trials are required.",

Diabetic retinopathy (DR) is associated with progressive microvascular rarefaction, but the effect of lens status on OCTA-derived vascular metrics remains underexplored. In this prospective observational study, 107 diabetic eyes imaged between March and August 2025 at Drashti Netralaya underwent high-resolution OCTA using the Heidelberg Spectralis platform. OCTEVA software enabled automated segmentation of the superficial (SCP), intermediate (ICP), and deep capillary plexuses (DCP). Quantitative measurements included vessel area density, branchpoint density, fractal dimension, and FAZ area. Lens status was classified as phakic or pseudophakic. Between-group comparisons were performed using Mann-Whitney U tests with Holm correction for multiple comparisons, and Cohen's d was calculated for effect size. Pseudophakic eyes exhibited significantly reduced vascular density (SCP: 44.7 \u00b1 6.2% vs 48.5 \u00b1 5.9%, P = 0.004; ICP: 33.8 \u00b1 4.5% vs 36.7 \u00b1 4.3%, P = 0.008; DCP: 34.2 \u00b1 4.9% vs 37.9 \u00b1 5.1%, P = 0.005) and lower fractal dimension (SCP: 1.39 \u00b1 0.06 vs 1.42 \u00b1 0.05, P = 0.011). FAZ area was significantly larger in pseudophakic eyes (0.37 \u00b1 0.09 mm\u00b2 vs 0.32 \u00b1 0.08 mm\u00b2, P = 0.018). Central macular thickness was slightly increased in pseudophakic eyes but not statistically significant (P = 0.07). Pseudophakic eyes demonstrate measurable microvascular compromise and FAZ enlargement compared with phakic eyes, reflecting advanced diabetic disease burden. Lens status should be considered when interpreting OCTA biomarkers in DR research and clinical assessment.",
        "42379280": "ID: 42379280\nTitle: Metabolomics approach using UHPLC/QE-MS for the mechanism of He Xue Ming Mu tablets on non-proliferative diabetic retinopathy.\nAbstract: He Xue Ming Mu Tablets (HXMMT) are traditional Chinese medicine formulations used in clinical practice for the treatment of diabetic retinopathy. The primary purpose of this article is to illuminate the potential mechanistic pathways underlying its therapeutic efficacy in non-proliferative diabetic retinopathy. UHPLC/QE-MS was used for plasma metabolomics analysis of 10 HXMMT-treated NPDR patients, 10 untreated NPDR patients, and 10 healthy controls. To identify differential metabolites, principal component analysis (PCA) for visualizing metabolic variation and hierarchical clustering for grouping samples by metabolic profiles, were combined with Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis to investigate related biological pathways. Intraocular pressure (IOP), best-corrected visual acuity (BCVA), central foveal thickness (CFT), and inflammatory/angiogenic markers (IL-6, TNF-\u03b1, VEGF, Ang-2) were assessed, with correlations analyzed between altered metabolites and clinical indices. HXMMT significantly improved macular edema, reduced fundus hemorrhage, and attenuated retinal inflammation (P\u202f<\u202f0.05). Metabolomic profiling identified a total of 813 plasma metabolites, and 283 metabolites exhibited distinct expression patterns that effectively discriminated NPDR patients from healthy controls, while 39 metabolites were found to distinguish between untreated NPDR patients and those who received HXMMT treatment. Consequently, 12 key metabolites showed significant covariance with clinical parameters of NPDR (P\u202f<\u202f0.05), suggesting their potential role as critical mediators in the pharmacodynamic mechanism of HXMMT. HXMMT exerts therapeutic effects on NPDR by targeting 12 plasma metabolites, particularly via the glycerophospholipid metabolic axis, providing a mechanistic basis for its clinical use.",
        "42379864": "ID: 42379864\nTitle: [Construction of a regulated Crat overexpression system in mouse hippocampal neuronal HT22 cell line].\nAbstract: Objective: To construct an inducible carnitine acetyltransferase (Crat) gene expression system and provide a controllable experimental platform for research on neuroprotection in glaucoma. Methods: This experimental study was conducted from January 2025 to November 2025 using the mouse hippocampal neuronal HT22 cell line. A high-efficiency tetracycline-inducible lentiviral gene expression system was established by optimizing the multiplicity of infection (MOI) and polybrene concentration, as well as comparing the activities of the cytomegalovirus (CMV) promoter and the elongation factor 1\u03b1 (EF1A) promoter. According to promoter type, the cells were divided into two groups: the CMV promoter group, in which enhanced green fluorescent protein (EGFP) fluorescence was detected, and the EF1A promoter group, in which mCherry fluorescence was detected. Conditional Crat overexpression was induced by doxycycline (Dox). Unmodified HT22 cells were assigned to an uninfected control group and an uninfected Dox-treated group, whereas successfully constructed HT22-TRE-mCrat/rtTA cells were assigned to an infected non-Dox-treated group and an infected Dox-treated group. The neuroprotective effect of the Crat overexpression system was evaluated in an H2O2-induced oxidative injury model by measuring lactate dehydrogenase (LDH) release, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining, and the mRNA expression levels of apoptosis-related factors, including caspase-3, B-cell lymphoma 2-associated X protein (Bax), and B-cell lymphoma 2 (Bcl-2), using quantitative PCR (qPCR). Statistical analyses were performed using the independent-samples t-test or one-way analysis of variance, with Tukey's test for pairwise comparisons. Results: A tetracyline-inducible gene expression system was successfully constructed and stably established in HT22 cells. The EF1A promoter showed higher driving efficiency than the CMV promoter, with a significantly greater number of positive cells in the EF1A promoter group than in the CMV promoter group [(303.0\u00b128.0) vs. (88.7\u00b111.4) cells; t=17.37, P<0.001]. In the H\u2082O\u2082-induced oxidative injury model, the LDH release rate was significantly lower in the infected Dox-treated group than in the uninfected Dox-treated group (27.1%\u00b14.7% vs. 49.8%\u00b18.2%; P<0.001). The apoptotic cell rate determined by TUNEL staining was significantly lower in the infected Dox-treated group than in the uninfected Dox-treated group (14.1%\u00b13.4% vs. 41.3%\u00b14.1%; t=16.23, P<0.001). The caspase-3 mRNA level was significantly lower in the infected Dox-treated group than in the uninfected Dox-treated group (140.3\u00b117.1 vs. 192.0\u00b124.3; t=4.26, P=0.002). Bax mRNA expression was significantly lower in the infected Dox-treated group than in the uninfected Dox-treated group (132.0\u00b113.1 vs. 169.8\u00b112.6; t=5.09, P<0.001). Bcl-2 mRNA expression was significantly higher in the infected Dox-treated group than in the uninfected Dox-treated group (83.2\u00b16.9 vs. 58.3\u00b18.1; t=5.74, P<0.001). All of these differences were statistically significant. Conclusion: This study successfully established a controllable Crat overexpression platform using the mouse hippocampal neuronal HT22 cell line, enabling temporal regulation of Crat gene expression and cell-specific studies in this cell line. \u76ee\u7684\uff1a \u6784\u5efa\u53ef\u8c03\u63a7\u7684\u8089\u78b1\u4e59\u9170\u8f6c\u79fb\u9176\uff08Crat\uff09\u8fc7\u8868\u8fbe\u57fa\u56e0\u7cfb\u7edf\u3002 \u65b9\u6cd5\uff1a \u5b9e\u9a8c\u7814\u7a76\u3002\u4e8e2025\u5e741\u6708\u81f311\u6708\uff0c\u91c7\u7528\u5c0f\u9f20\u6d77\u9a6c\u795e\u7ecf\u5143\u7ec6\u80de\u7cfbHT22\u8fdb\u884c\u5b9e\u9a8c\u3002\u901a\u8fc7\u4f18\u5316\u6162\u75c5\u6bd2\u611f\u67d3\u590d\u6570\uff08MOI\uff09\u53ca\u805a\u51dd\u80fa\u6d53\u5ea6\uff0c\u6bd4\u8f83\u5de8\u7ec6\u80de\u75c5\u6bd2\uff08CMV\uff09\u4e0e\u5ef6\u4f38\u56e0\u5b501\u03b1\uff08EF1A\uff09\u542f\u52a8\u5b50\u9a71\u52a8\u6548\u7387\uff0c\u5efa\u7acb\u9ad8\u6548\u56db\u73af\u7d20\u8bf1\u5bfc\u578b\uff08Tet-On\uff09\u6162\u75c5\u6bd2\u57fa\u56e0\u8868\u8fbe\u7cfb\u7edf\u3002\u6839\u636e\u542f\u52a8\u5b50\u7c7b\u578b\uff0c\u5c06\u7ec6\u80de\u5206\u4e3a\u4e24\u7ec4\uff1aCMV\u542f\u52a8\u5b50\u7ec4\uff08\u68c0\u6d4bEGFP\u8367\u5149\uff09\u548cEF1A\u542f\u52a8\u5b50\u7ec4\uff08\u68c0\u6d4bmCherry\u8367\u5149\uff09\u3002\u7ecf\u591a\u897f\u73af\u7d20\uff08Dox\uff09\u8bf1\u5bfc\u540e\u5b9e\u73b0Crat\u6761\u4ef6\u6027\u8fc7\u8868\u8fbe\u3002\u5c06\u666e\u901aHT22\u7ec6\u80de\u5206\u4e3a\u672a\u611f\u67d3\u5bf9\u7167\u7ec4\u548c\u672a\u611f\u67d3\u6dfb\u52a0Dox\u7ec4\uff1b\u5c06\u5df2\u6210\u529f\u6784\u5efa\u7684HT22-TRE-mCrat/rtTA\u7ec6\u80de\u5206\u4e3a\u611f\u67d3\u672a\u6dfb\u52a0Dox\u7ec4\u53ca\u611f\u67d3\u6dfb\u52a0Dox\u7ec4\u3002\u5229\u7528H\u2082O\u2082\u8bf1\u5bfc\u7684\u6c27\u5316\u635f\u4f24\u6a21\u578b\uff0c\u901a\u8fc7\u4e73\u9178\u8131\u6c22\u9176\uff08LDH\uff09\u91ca\u653e\u3001\u672b\u7aef\u8131\u6c27\u6838\u82f7\u9178\u8f6c\u79fb\u9176\u6807\u8bb0\u6cd5\uff08TUNEL\uff09\u67d3\u8272\u53caqPCR\u68c0\u6d4b\u51cb\u4ea1\u76f8\u5173\u56e0\u5b50\u534a\u80f1\u5929\u51ac\u9176-3\uff08Caspase-3\uff09\u3001B\u6dcb\u5df4\u7ec6\u80de\u7624-2\u76f8\u5173X\u86cb\u767d\uff08Bax\uff09\u3001B\u6dcb\u5df4\u7ec6\u80de\u7624-2\uff08Bcl-2\uff09\u7684mRNA\u8868\u8fbe\u6c34\u5e73\uff0c\u8bc4\u4ef7Crat\u8fc7\u8868\u8fbe\u7cfb\u7edf\u7684\u795e\u7ecf\u4fdd\u62a4\u4f5c\u7528\u3002\u91c7\u7528\u72ec\u7acb\u6837\u672ct\u68c0\u9a8c\u548c\u5355\u56e0\u7d20\u65b9\u5dee\u5206\u6790\u8fdb\u884c\u7edf\u8ba1\u5b66\u5206\u6790\u3002 \u7ed3\u679c\uff1a \u6210\u529f\u5728HT22\u7ec6\u80de\u4e2d\u6784\u5efa\u5e76\u7a33\u5b9a\u8868\u8fbeTet-On\u53ef\u8bf1\u5bfc\u57fa\u56e0\u8868\u8fbe\u7cfb\u7edf\u3002EF1A\u542f\u52a8\u5b50\u9a71\u52a8\u6548\u7387\u4f18\u4e8eCMV\u542f\u52a8\u5b50\uff0cEF1A\u542f\u52a8\u5b50\u7ec4\u9633\u6027\u7ec6\u80de\u6570\uff3b\uff08303.0\u00b128.0\uff09\u4e2a\uff3d\u9ad8\u4e8eCMV\u542f\u52a8\u5b50\u7ec4\uff3b\uff0888.7\u00b111.4\uff09\u4e2a\uff3d\uff0c\u5dee\u5f02\u6709\u7edf\u8ba1\u5b66\u610f\u4e49\uff08t=17.37\uff0cP<0.001\uff09\u3002\u5728H\u2082O\u2082\u6c27\u5316\u635f\u4f24\u6a21\u578b\u4e2d\uff0c\u611f\u67d3\u6dfb\u52a0Dox\u7ec4LDH\u91ca\u653e\u7387\uff0827.1%\u00b14.7%\uff09\u4f4e\u4e8e\u672a\u611f\u67d3\u6dfb\u52a0Dox\u7ec4\uff0849.8%\u00b18.2%\uff09\uff0c\u5dee\u5f02\u6709\u7edf\u8ba1\u5b66\u610f\u4e49\uff08P<0.001\uff09\uff1bTUNEL\u67d3\u8272\u51cb\u4ea1\u7ec6\u80de\u7387\uff0814.1%\u00b13.4%\uff09\u4f4e\u4e8e\u672a\u611f\u67d3\u6dfb\u52a0Dox\u7ec4\uff0841.3%\u00b14.1%\uff09\uff0c\u5dee\u5f02\u6709\u7edf\u8ba1\u5b66\u610f\u4e49\uff08t=16.23\uff0cP<0.001\uff09\uff1bCaspase-3 mRNA\u6c34\u5e73\uff08140.3\u00b117.1\uff09\u4f4e\u4e8e\u672a\u611f\u67d3\u6dfb\u52a0Dox\u7ec4\uff08192.0\u00b124.3\uff1bt=4.26\uff0cP=0.002\uff09\uff1bBax mRNA\u8868\u8fbe\u6c34\u5e73\uff08132.0\u00b113.1\uff09\u4f4e\u4e8e\u672a\u611f\u67d3\u6dfb\u52a0Dox\u7ec4\uff08169.8\u00b112.6\uff1bt=5.09\uff0cP<0.001\uff09\uff1bBcl-2 mRNA\u8868\u8fbe\u6c34\u5e73\uff0883.2\u00b16.9\uff09\u9ad8\u4e8e\u672a\u611f\u67d3\u6dfb\u52a0Dox\u7ec4\uff0858.3\u00b18.1\uff1bt=5.74\uff0cP<0.001\uff09\u3002 \u7ed3\u8bba\uff1a \u91c7\u7528\u5c0f\u9f20\u6d77\u9a6c\u795e\u7ecf\u5143\u7ec6\u80de\u7cfbHT22\u6210\u529f\u5efa\u7acb\u4e86\u53ef\u63a7\u7684Crat\u8fc7\u8868\u8fbe\u5e73\u53f0\uff0c\u53ef\u5728\u8be5\u7ec6\u80de\u7cfb\u4e2d\u5b9e\u73b0\u5bf9Crat\u57fa\u56e0\u8868\u8fbe\u7684\u65f6\u5e8f\u8c03\u63a7\u4e0e\u7ec6\u80de\u7279\u5f02\u6027\u7814\u7a76\u3002.",
        "42379865": "ID: 42379865\nTitle: [Regulation of SARM1 on SNPH expression and its participation in glaucomatous optic neuropathy].\nAbstract: Objective: To investigate the molecular mechanism of toll-like receptor adaptor protein SARM1 in glaucomatous optic neuropathy. Methods: The experimental study was conducted from February 2024 to October 2025. A chronic ocular hypertension glaucoma model was established by injecting micro-magnetic beads into the anterior chamber of 8- to 10-week-old male Wistar rats. At 3 days, 1 week, and 2 weeks post-modeling, retinal and optic nerve tissues from 6 eyes of 6 rats were collected as the chronic ocular hypertension glaucoma model group, and 6 eyes from 6 wild-type rats that received an equal volume of saline via anterior chamber injection served as the control group. Intraocular pressure was measured using a TonoLab tonometer. Retinal whole-mounts were prepared and POU domain class 4 transcription factor 1 (POU4F1 or Brn3A) immunofluorescence staining was used to detect retinal ganglion cell loss. Western blotting was performed to detect the expression levels of SARM1 and SNPH in the rat retina and optic nerve. Immunofluorescence staining was used to examine their distribution in these tissues. Furthermore, CRISPR/Cas9 technology was used to knock down the expression of SARM1 and SNPH in mouse 661W retinal ganglion cells, respectively. Cells were collected 48 hours after transfection, and Western blotting was performed to detect the expression levels of SARM1 and SNPH. Normally distributed continuous data are presented as mean\u00b1SEM. Comparisons between two groups were performed using the Student's t-test, while comparisons among multiple groups were assessed by the one-way analysis of variance followed by the Tukey's multiple comparisons test. Results: Western blot analysis revealed that in the glaucoma model group, the relative expression level of SARM1 protein in the optic nerve at one week post-modeling (1.22\u00b10.06) was significantly higher than that in the control group (1.03\u00b10.01; P=0.027, q=4.38). In contrast, the expression level of SARM1 in the retina at three days post-modeling (0.79\u00b10.02) was significantly lower than that in the control group (1.04\u00b10.03; P<0.001, q=6.86). Concurrently, the expression level of SNPH at three days post-modeling (0.74\u00b10.01) was lower than that in the control group (1.03\u00b10.04; P=0.040, q=0.58), and its expression at one week post-modeling (1.19\u00b10.10; P=0.002, q=4.36) was significantly higher than that at three days (0.74\u00b10.01). Consistent with the Western blot results, immunofluorescence staining results showed that in the optic nerve of the glaucoma model group, the expression of SARM1 was significantly higher than that in the control group at one week post-modeling, while the expression of SNPH was lower than that in the control group at three days post-modeling. Both proteins partially co-localized with the neuronal marker \u03b23-tubulin. Immunofluorescence staining also revealed co-localization of these two proteins within axons. Additionally, SARM1 co-localized with the mitochondrial marker protein TOM20. Western blot results from 661W cells showed that the knockdown of SARM1 expression (0.54\u00b10.04) significantly reduced SNPH expression (0.54\u00b10.05; P=0.003, q=7.98), whereas the knockdown of SNPH expression (0.39\u00b10.06) did not markedly affect SARM1 levels (0.75\u00b10.05; P=0.010, q=6.39). Conclusion: The elevated expression of SARM1 protein in the axons of the rat glaucoma model can promote retinal ganglion cell axonal pathology by localizing to axonal mitochondria and regulating SNPH expression. \u76ee\u7684\uff1a \u63a2\u8ba8Toll\u6837\u53d7\u4f53\u9002\u914d\u86cb\u767d\u542b\u65e0\u83cc\u03b1\u57fa\u5e8f\u53caToll/\u767d\u4ecb\u7d20\u53d7\u4f53\u57fa\u5e8f\u86cb\u767d1\uff08SARM1\uff09\u8c03\u63a7\u8f74\u7a81\u7ebf\u7c92\u4f53\u951a\u5b9a\u86cb\u767d\uff08SNPH\uff09\u8868\u8fbe\u53c2\u4e0e\u9752\u5149\u773c\u89c6\u795e\u7ecf\u75c5\u53d8\u7684\u673a\u5236\u3002 \u65b9\u6cd5\uff1a \u5b9e\u9a8c\u7814\u7a76\uff0c\u4e8e2024\u5e742\u6708\u81f32025\u5e7410\u6708\u5f00\u5c55\u3002\u7528\u7b80\u5355\u968f\u673a\u6cd5\u5c068~10\u5468Wistar\u96c4\u6027\u5927\u9f20\u5206\u4e3a\u5bf9\u7167\u7ec4\u548c\u9752\u5149\u773c\u6a21\u578b\u7ec4\uff0c\u6bcf\u7ec46\u53ea\u52a8\u7269\uff0c\u5747\u53d6\u53f3\u773c\u7eb3\u5165\u5b9e\u9a8c\u3002\u6a21\u578b\u7ec4\u8fdb\u884c\u524d\u623f\u5fae\u7c92\u78c1\u73e0\u6ce8\u5c04\uff0c\u6784\u5efa\u6162\u6027\u9ad8\u773c\u538b\u9752\u5149\u773c\u6a21\u578b\uff0c\u5728\u9020\u6a21\u540e3 d\u30011\u5468\u548c2\u5468\u53d6\u89c6\u7f51\u819c\u548c\u89c6\u795e\u7ecf\u8fdb\u884c\u5b9e\u9a8c\uff1b\u5bf9\u7167\u7ec4\u5927\u9f20\u524d\u623f\u6ce8\u5c04\u7b49\u4f53\u79ef\u751f\u7406\u76d0\u6c34\u3002\u4f7f\u7528TonoLab\u773c\u538b\u8ba1\u6d4b\u91cf\u5927\u9f20\u773c\u538b\u3002\u91c7\u7528\u89c6\u7f51\u819c\u94fa\u7247Brn3A\u514d\u75ab\u8367\u5149\u67d3\u8272\u68c0\u6d4b\u89c6\u7f51\u819c\u795e\u7ecf\u8282\u7ec6\u80de\uff08RGC\uff09\u4e22\u5931\u60c5\u51b5\u3002\u91c7\u7528Western\u5370\u8ff9\u68c0\u6d4b\u5927\u9f20\u89c6\u7f51\u819c\u548c\u89c6\u795e\u7ecf\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\u60c5\u51b5\u3002\u91c7\u7528\u514d\u75ab\u8367\u5149\u67d3\u8272\u6cd5\u68c0\u6d4b\u5927\u9f20SARM1\u548cSNPH\u5728\u89c6\u7f51\u819c\u548c\u8f74\u7a81\u4e2d\u7684\u8868\u8fbe\u5206\u5e03\u60c5\u51b5\u3002\u5e76\u5229\u7528\u6210\u7c07\u89c4\u5f8b\u95f4\u9694\u77ed\u56de\u6587\u91cd\u590d\u5e8f\u5217\uff08CRISPR\uff09/\u6838\u9178\u5185\u5207\u91769\uff08Cas9\uff09\u6280\u672f\u5206\u522b\u964d\u4f4e\u5c0f\u9f20\u89c6\u7f51\u819c\u795e\u7ecf\u8282\u7ec6\u80de\u7cfb661W\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\uff0c\u8f6c\u67d348 h\u540e\u6536\u96c6\u7ec6\u80de\u3002\u91c7\u7528Western\u5370\u8ff9\u68c0\u6d4b\u7ec6\u80de\u4e2dSARM1\u548cSNPH\u7684\u8868\u8fbe\u60c5\u51b5\u3002\u91c7\u7528\u72ec\u7acb\u6837\u672ct\u68c0\u9a8c\u3001\u5355\u56e0\u7d20\u65b9\u5dee\u5206\u6790\u3001Tukey\u591a\u91cd\u6bd4\u8f83\u8fdb\u884c\u7edf\u8ba1\u5b66\u5206\u6790\u3002 \u7ed3\u679c\uff1a Western\u5370\u8ff9\u7ed3\u679c\u663e\u793a\uff0c\u6a21\u578b\u7ec4\u9020\u6a21\u540e1\u5468\uff0c\u89c6\u795e\u7ecf\u4e2d\u7684SARM1\u86cb\u767d\u7684\u76f8\u5bf9\u8868\u8fbe\u91cf\uff081.22\u00b10.06\uff09\u9ad8\u4e8e\u5bf9\u7167\u7ec4\uff081.03\u00b10.01\uff0cP=0.027\uff0cq=4.38\uff09\u3002\u800c\u89c6\u7f51\u819c\u4e2dSARM1\u86cb\u767d\u8868\u8fbe\u91cf\u5728\u9020\u6a21\u540e3 d\uff080.79\u00b10.02\uff09\u4f4e\u4e8e\u5bf9\u7167\u7ec4\uff081.04\u00b10.03\uff0cP<0.001\uff0cq=6.86\uff09\u3002SNPH\u7684\u8868\u8fbe\u91cf\u5728\u9020\u6a21\u540e3 d\uff080.74\u00b10.01\uff09\u4f4e\u4e8e\u5bf9\u7167\u7ec4\uff081.03\u00b10.04\uff0cP=0.040\uff0cq=0.58\uff09\uff0c\u5e76\u5728\u9020\u6a21\u540e1\u5468\uff081.19\u00b10.10\uff0cP=0.002\uff0cq=4.36\uff09\u8868\u8fbe\u91cf\u9ad8\u4e8e\u9020\u6a21\u540e3 d\uff080.74\u00b10.01\uff09\u3002\u514d\u75ab\u8367\u5149\u67d3\u8272\u7ed3\u679c\u663e\u793a\uff0c\u6a21\u578b\u7ec4RGC\u8f74\u7a81\u4e2dSARM1\u7684\u8868\u8fbe\u5728\u9020\u6a21\u540e1\u5468\u9ad8\u4e8e\u5bf9\u7167\u7ec4\uff0cSNPH\u7684\u8868\u8fbe\u5728\u9020\u6a21\u540e3 d\u4f4e\u4e8e\u5bf9\u7167\u7ec4\u4e0eWestern\u5370\u8ff9\u7ed3\u679c\u4e00\u81f4\u3002\u5e76\u4e14\u90fd\u4e0e\u795e\u7ecf\u5143\u6807\u5fd7\u7269\u5fae\u7ba1\u86cb\u767d\u90e8\u5206\u5171\u5b9a\u4f4d\u3002\u5e76\u4e14\u514d\u75ab\u8367\u5149\u67d3\u8272\u7ed3\u679c\u8fd8\u663e\u793a\u8fd9\u4e24\u79cd\u86cb\u767d\u5728\u89c6\u795e\u7ecf\u4e2d\u5171\u5b9a\u4f4d\u3002SARM1\u4e0e\u7ebf\u7c92\u4f53\u6807\u5fd7\u7269\u86cb\u767dTOM20\u5171\u5b9a\u4f4d\u3002661W\u7ec6\u80de\u4e2dWestern\u5370\u8ff9\u7ed3\u679c\u663e\u793a\uff0cSARM1\u8868\u8fbe\u964d\u4f4e\uff080.54\u00b10.04\uff09\u53ef\u964d\u4f4eSNPH\uff080.54\u00b10.05\uff0cP=0.003\uff0cq=7.98\uff09\u7684\u8868\u8fbe\uff0c\u4f46SNPH\u8868\u8fbe\u964d\u4f4e\uff080.39\u00b10.06\uff09\u5bf9SARM1\u8868\u8fbe\u5f71\u54cd\u8f83\u5c0f\uff080.75\u00b10.05\uff0cP=0.010\uff0cq=6.39\uff09\u3002 \u7ed3\u8bba\uff1a SARM1\u86cb\u767d\u5728\u5927\u9f20\u9752\u5149\u773c\u6a21\u578b\u7ec4\u4e2d\u7684\u89c6\u795e\u7ecf\u4e2d\u8868\u8fbe\u5347\u9ad8\uff0c\u901a\u8fc7\u5b9a\u4f4d\u4e8e\u7ebf\u7c92\u4f53\u8c03\u63a7SNPH\u8868\u8fbe\u53c2\u4e0eRGCs\u89c6\u795e\u7ecf\u75c5\u53d8\u3002.",

This study evaluated the long-term visual prognosis of patients with type 2 diabetes (T2D) by assessing real-world DME treatment outcomes. Patients with T2D and DME at Oulu University Hospital during 2010-2023 were included. The effect of DME intervention (anti-VEGF-agents, macular laser or both, intravitreal corticosteroids, observation) was evaluated by changes in visual acuity (VA) and residual edema. The dataset comprised additional variables, including age, sex, age at T2D diagnosis, timing of onset for diabetic retinopathy (DR) and DME, DR severity, glucose levels, other comorbidities, occurrences of treatment interruption, and adverse effects related to intravitreal therapy. Of 549 screened patients with T2D, 1145 DME episodes in 355 patients (560 eyes) were included. Mean ages at T2D, DR, and DME diagnosis were 51.0, 61.7, and 66.4 years, respectively. Mean HbA1c at DME treatment initiation was 64.3 mmol/mol; 93.0% had hypertension medication and 47.6% had diabetic nephropathy. DME was most treated with anti-VEGF injections alone (55.3%) or combined with laser (20.4%), yielding mean VA improvements of 3.8 [3.0-4.6] and 3.6 [2.5-4.6] ETDRS letters (both p\u2009<\u20090.001), respectively. Intravitreal corticosteroids (3.1%) resulted in a gain of 4.3 [1.2-7.4] letters (p\u2009=\u20090.014), whereas macular laser alone (12.8%) and observation (8.3%) showed no significant effect. Residual edema occurred in 38.1% (anti-VEGF), 43.2% (combination), 54.7% (observation), and 80.6% (corticosteroid) of cases. Adverse events related to any DME treatment were rare. Despite recurrent episodes of DME, most patients with T2D experienced improvement in visual acuity. Anti-VEGF agents alone or combined with macular laser appeared to be beneficial in terms of both visual gain and reduction of edema.",

Previous study has shown that adipose stem cell-derived extracellular vesicles (ADSC-EVs) can alleviate glutamate-induced retinal ganglion cells (RGCs) death by suppressing protein kinase C alpha (PKCA) pathway and increasing the expression of \u03b1-amino-3-hydroxy-5-methyl-4-isoxazoleproprionic acid receptors (AMPARs) subunit 2 (GluA2) on the cell membrane, but the mechanisms remain unexplored. To clarify the molecular processes involved in ADSC-EVs-mediated intracellular calcium balance, we isolated ADSC-EVs using ultrafiltration and ultracentrifugation, and characterized these vesicles by transmission electron microscopy, nanoparticle tracking analysis, and flow cytometry. Small RNA sequencing was performed on glutamate-injured rat retinal precursor (R28) cells pre-treated with ADSC-EVs or PBS. Through bioinformatic analysis, we identified candidate microRNAs and predicted their potential target genes. The regulatory effects of microRNA were confirmed using propidium iodide staining, Fluo-4AM staining, western blotting, and immunofluorescence. Additionally, the RGCs counting and visual function tests were employed to evaluate the therapeutic efficacy of the microRNA in the glutamate-induced SD rat - animal model. Our results demonstrated that pre-treatment with ADSC-EVs led to a significant increase in the expression levels of miR-127-3p, miR-181b-1-3p, miR-199a-3p/5p, miR-23a-5p, miR-23b-5p, and miR-486 in R28 cells. Bioinformatic analyses suggest that miR-23a-5p may contribute to regulating the calcium overload by inhibiting the expression of phospholipase C delta 1 (PLCD1). Overexpression of miR-23a-5p or pre-treatment with ADSC-EVs modulated the expression of GluA2 on the cell membrane through inhibiting the PLCD1/PKCA/GluA2 axis, thereby reducing intracellular calcium levels and diminishing R28 cell death. In contrast, inhibition of miR-23a-5p expression partially reversed the regulatory effects of ADSC-EVs on calcium concentration and cell viability. Furthermore, our findings suggest that overexpression of miR-23a-5p in retina alleviated glutamate-induced RGCs death and visual function impairment, whereas suppression of miR-23a-5p exacerbated glutamate-induced RGCs death. ADSC-EVs delived miR-23a-5p mitigate glutamate-induced RGCs damage by inhibiting the PLCD1/PKCA/GluA2 axis. Targeting this miR-23a-5p-mediated axis may therefore represent a promising therapeutic approach for excitotoxic RGCs injury.",

A publicly available five-class DR fundus dataset of 3,500 color photographs graded using the International Clinical Diabetic Retinopathy (ICDR) scale was used. A standardized workflow was applied across eight Convolutional Neural Network (CNN) architectures (AlexNet, Densely Connected Convolutional Network 121 (DenseNet121), Residual Network 50 (ResNet50), eXtreme Inception (Xception), Mobile Network Version 2 (MobileNetV2), Efficient Network Version 2 B2 (EfficientNetV2B2), Inception Version 3 (InceptionV3), Visual Geometry Group 16 (VGG16)), including a 70/20/10 train/validation/test split, optional histogram-based contrast enhancement, strong on-the-fly augmentations, and class-balanced sampling. Seven architectures (DenseNet121, ResNet50, Xception, MobileNetV2, EfficientNetV2B2, InceptionV3, and VGG16) were initialized using ImageNet-pretrained weights and trained using a two-stage transfer-learning strategy with backbone freezing followed by partial fine-tuning, while AlexNet was implemented as a custom architecture and trained from randomly initialized weights. For five-class grading, VGG16 achieved the highest accuracy (0.7686) and weighted Jaccard index (0.6572), while EfficientNetV2B2 provided the best balanced accuracy (0.6128) and macro Area Under the Receiver Operating Characteristic Curve (AUROC 0.9158). Misclassifications were concentrated between adjacent severity levels. For binary DR screening, modern backbones achieved \u22650.94 accuracy and balanced accuracy; selected models reached AUROC \u22480.982-0.990 and Area Under the Precision-Recall Curve (AUPRC)\u2009\u2248\u20090.987-0.992. The proposed DL pipeline delivers robust multiclass DR grading and highly discriminative binary screening using widely available CNN backbones. Operating-point calibration enables sensitivity-oriented triage or specificity-oriented confirmation, supporting teleophthalmology and task-shifted DR screening programs to expand coverage and reduce preventable vision loss.

Automated classification of DR stages from retinal fundus images can assist clinicians in timely diagnosis and management. This study proposes a hybrid approach that combines deep learning-based feature extraction with traditional machine learning classifiers for automatic DR stage classification. Two datasets were used: Dataset A (DiabeticRetinopathy_Messidor_EyePACS_Preprocessed) and Dataset B (APTOS 2019 Blindness Detection). Three hybrid architectures were evaluated: MobileNetV2 with Support Vector Machine (SVM), MobileNetV2 with Random Forest (RF), and VGG16 with SVM. The models exploit convolutional neural networks for extracting discriminative features and employ conventional classifiers for robust decision-making. Grad-CAM and Score-CAM techniques were applied to enhance interpretability by visualizing the regions influencing model predictions. Experimental results on Dataset B show that MobileNetV2\u2009+\u2009SVM achieved an accuracy of 85%, precision of 72%, recall of 75%, and F1 score of 73%, while MobileNetV2\u2009+\u2009RF achieved an accuracy of 85%, precision of 74%, recall of 72%, and F1 score of 73%. These results indicate that lightweight CNNs combined with traditional classifiers can produce reliable and interpretable DR stage predictions. The study highlights the potential of hybrid models for clinical deployment, offering accurate, transparent, and efficient tools to support ophthalmologists in DR screening and management. Future work will focus on addressing data imbalance, improving model generalizability, and integrating these methods into real-world clinical diagnostic systems.

In ophthalmology, aptamer-based platforms have emerged as effective solutions for managing retinal diseases, glaucoma, and ocular surface disorders. This review provides a comprehensive overview of aptamers that have received approval or are in experimental, preclinical, or clinical development stages for ocular diseases. A narrative literature search was conducted using PubMed, Scopus, Cochrane Library, Embase, and Web of Science databases, concentrating on aptamers that have reached experimental, preclinical, clinical, or FDA-approved stages. Studies published up to March 2026 were screened according to predefined inclusion and exclusion criteria, based on their reported efficacy, molecular targets, and relevance to ocular diseases. Twenty-four records were included, comprising 24 aptamer-based platforms. Across ocular diseases, aptamers were identified in three principal application domains: therapeutic intervention, diagnostic, and targeted drug delivery. In age-related macular degeneration, aptamers development was predominantly therapeutic, with agents targeting vascular endothelial growth factor, platelet-derived growth factor, fibroblast growth factor 2, complement components, nucleolin, CBF1, and CD44. In glaucoma, aptamers were mainly directed toward neuroprotection, antifibrotic modulation, aqueous humor outflow regulation, biomarker detection, and topical drug delivery. In ocular surface diseases, aptamers were primarily developed for antimicrobial and antiviral therapy, antiangiogenic treatment, anti-allergic modulation, corneal surface targeting, and controlled topical drug delivery. Overall, aptamers demonstrated broad translational versatility across both posterior and anterior segment diseases. The available evidence demonstrates a diverse and rapidly expanding repertoire of aptamers developed for ocular diseases, underscoring their versatile potential as next-generation platforms for therapeutic, biomarker-guided diagnosis, and targeted drug delivery in ophthalmology.",

Despite insufficient response to high-dose intravenous steroid therapy, teprotumumab led to marked improvement in proptosis, orbital inflammation, and visual function. However, treatment was associated with progressive and persistent sensorineural hearing loss after completing eight infusions. Auditory symptoms began after the fifth infusion with intermittent aural fullness and sound reverberation, progressing to mild down-sloping sensorineural hearing loss. Nine days after the final infusion, the four-frequency pure-tone average (PTA4) was 21.25 dB hearing level (HL) in the right ear and 27.50 dB HL in the left ear. Despite initiation of oral prednisolone therapy (40 mg/day with tapering), progressive hearing loss was observed in the right ear, particularly in the low- to mid-frequency range (250-2,000 Hz), with thresholds worsening to 90 dB HL. At twenty days after the final infusion, PTA4 had increased to 75.00 dB HL in the right ear and 31.25 dB HL in the left ear. Serial audiometric assessments at 107, 128, and 198 days after the final infusion demonstrated no recovery. The patient's history of sudden sensorineural hearing loss suggests increased susceptibility to teprotumumab-associated ototoxicity. This case underscores the importance of individualized risk assessment, careful audiologic monitoring, and shared decision-making when balancing visual recovery against the risk of potentially irreversible auditory toxicity.",

Most research focuses on model insects like fruit flies, while common agricultural pests remain underexplored. This review integrates current knowledge of insect visual phototransduction to identify molecular and neural targets for precision pest management. This review systematically outlines the complete phototransduction pathway in insect vision: compound eyes and visual lobes exhibit structural specialization adapted to different ecological niches; rhodopsin synthesis and opsin diversity form the molecular foundation; the 'opsin-phospholipase-transient receptor potential channels' pathway and histamine-acetylcholine dual-transmitter branching achieve signal cascading and functional differentiation. Current research has led to the development of three environmentally friendly pest control technologies, first, vision-based traps that capture pests by optimizing spectral, polarization, and color properties of materials; second, molecular tools such as CRISPR/Cas9, RNA interference, and anti-sense DNA to target visual genes; and third, multimodal devices that combine sensory synergy with smart optical technologies for physical interception. Existing vision-based pest control methods still face significant limitations in field applications and tend to be highly species-specific. Future efforts should integrate basic vision research with practical applications to drive the transition from chemical dependency to ecologically friendly and precision pest management. \u00a9 2026 Society of Chemical Industry.",

Upregulation of sirtuin 1 (SIRT1), a nicotinamide adenine dinucleotide (NAD)-dependent deacetylase, reduces RGC loss and vision deficits in TON models, but mechanisms underlying these effects are not well understood. This study examined if Nrf2, a transcription factor that regulates antioxidant enzymes, helps mediate neuroprotective effects of SIRT1 in TON. Wild-type (WT) and Nrf2-deficient mice received an intravitreal injection with adeno-associated virus type 2 (AAV2) expressing an RGC-selective promoter-driven human SIRT1, green fluorescent protein (GFP), or Nrf2. TON was induced by repetitive mild head impacts, and vision was assessed by optokinetic responses (OKRs). RGCs from isolated retinas were immunolabeled with Brn3a antibodies and counted to quantify Brn3a+ RGC numbers. TON resulted in decreased Brn3a labeling and decreased OKR scores in AAV2/synuclein gamma (SNCG)/GFP-injected WT mice as compared with unimpacted mice; AAV2/SNCG/SIRT1 treatment attenuated this loss. This protective effect was absent in Nrf2-deficient mice subjected to TON, as these mice had significant decreases in Brn3a-labeled cells and OKR scores whether they received AAV2/SNCG/GFP or AAV2/SNCG/SIRT1 therapy. AAV2/SNCG/Nrf2-injected WT mice exhibited similar decreases in Brn3a labeling and OKR scores as AAV2/SNCG/GFP-injected WT mice. Nrf2 is implicated as an important downstream effector of SIRT1-mediated therapeutic effects given that Nrf2-deficient mice are unable to recapitulate the neuroprotective effects of AAV-based SIRT1 gene therapy. However, Nrf2 is not sufficient to induce similar neuroprotective effects when overexpressed selectively in RGCs. Results of this study define an important mechanism of SIRT1 gene therapy mediating RGC neuroprotection.",

Although CLRN1 expression has been localized to M\u00fcller glia (MG), the pathogenic mechanisms linking glial CLRN1 deficiency to photoreceptor death remain undefined. We utilized a novel large-animal model to elucidate cell-type-specific pathogenesis at single-nucleus resolution. CLRN1-/- rabbits were generated via CRISPR/Cas9. Retinal phenotyping included longitudinal optical coherence tomography (OCT), electroretinography (ERG), and histology for up to 3 years. Single-nucleus RNA sequencing (snRNA-seq) was performed at a pre-symptomatic stage (10 months, n = 3/genotype). Differentially expressed genes (DEGs) were identified using pseudobulk DESeq2 and validated via immunofluorescence. CLRN1-/- rabbits exhibited progressive outer nuclear layer thinning and delayed ERG responses starting after 20 months, mimicking human clinical kinetics. The snRNA-seq revealed that CLRN1 is exclusively expressed in a discrete subset (\u223c24%) of MG. Mutant MG exhibited transcriptomic downregulation of the adherens junction component CTNNA2, which was validated at the protein level by immunofluorescence staining. Photoreceptors exhibit extensive non-cell-autonomous dysregulation (232 rod and 68 cone DEGs) characterized by loss of the cone synaptic organizer TENM2 and rod-specific splicing dysregulation (CWF19L2). Concurrently, inner retinal neurons mounted a robust proteostatic response via HSP90 family upregulation (HSP90AB1, HSP90AA1, HSP90B1), a defensive signature absent in vulnerable photoreceptors. Our findings suggest an \"anchor-shield\" mechanism: MG CLRN1 loss compromises the outer limiting membrane (OLM) adhesion complex (\"anchor\"), and photoreceptors lack the proteostatic response (\"shield\") seen in resilient inner neurons. Restoring CLRN1 in M\u00fcller glia or implementing photoreceptor neuroprotection represents promising therapeutic strategies for USH3A.",

Pixel-wise RNFL rates of change were computed from longitudinal optic disc OCT scans of 15,242 eyes (8419 adults with POAG; Massachusetts Eye and Ear, 1998-2023). A loss-only constraint zeroed all thickening values, reflecting the biological prior that adult RNFL does not regenerate. Non-negative matrix factorization decomposed these maps into spatial progression components (80% training set). Components were evaluated in a held-out set (20%) for retinotopic structure-function concordance, visual field progressor classification against global and quadrant RNFL rates, and enrichment of genetic association signals at established POAG loci. Six anatomically distinct progression patterns emerged, including diffuse circumferential loss, focal peripapillary defects, and arcuate bundle degeneration. Pattern-based models provided significant incremental predictive information over global RNFL rate (integrated discrimination improvement, 0.049; P = 0.003), with concordant gains in discrimination (area under the curve, 0.795 vs. 0.768) and variance explained (pseudo-R\u00b2, 0.382 vs. 0.311). Structure-function mapping confirmed retinotopic coherence. In an exploratory genetic analysis, spatial pattern weights showed stronger association signals than the global RNFL rate at the majority of established POAG susceptibility loci, consistent with the hypothesis that spatial decomposition may reduce phenotypic heterogeneity. Glaucomatous structural progression occurs through spatially distinct modes with independent structure-function and preliminary genetic signatures that conventional RNFL averaging obscures.",

ON is characterized by inflammation of the optic nerve, demyelination, axonal damage, and retinal ganglion cell (RGC) loss. Previously, we showed that spermine oxidase (SMOX), a polyamine catabolizing enzyme, modulates visual function in an experimental model of ON. Using proteomic analysis, the present study aimed to identify SMOX-regulated molecular pathways involved in ON-associated visual dysfunction. Experimental autoimmune encephalomyelitis (EAE) was induced in wild-type (WT) and SMOX-deficient (Smox KO) mice. Clinical scoring of mice was recorded daily. Optic nerves from WT and Smox KO EAE mice and their controls were collected and analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Pathway enrichment and comparative analyses were performed to identify key processes and pathways regulated by SMOX. Immunofluorescence was performed to detect changes in the expression of key proteins. Smox KO EAE mice showed delayed and reduced clinical scores. Pathway enrichment analysis identified several key processes affected in EAE, including regulation of the actin cytoskeleton, tight junction integrity, and platelet activation/aggregation. The comparative analysis of the WT EAE and Smox KO EAE proteomes, together with false discovery rate (FDR)-corrected pathway enrichment analysis, indicated attenuation of neuroinflammatory pathways in the SMOX-deficient optic nerve. Furthermore, SMOX deficiency restored key cytoskeletal and cellular-adhesion proteins essential for neuronal integrity. Immunofluorescence studies confirmed dysregulation of receptor for activated C kinase 1 (RACK1), actinin alpha 4 (ACTN4), high mobility group box 1 (HMGB1), and S100 calcium-binding protein B (S100B), critical proteins involved in immune signaling, cytoskeletal stability, and inflammation. These findings indicate the impact of SMOX on inflammation and cytoskeletal stabilization in ON and its potential as a therapeutic target in preserving vision in MS.",

This study assessed the impact of subretinal drusenoid deposits (SDDs) on EZ-based quantitative metrics in nonneovascular age-related macular degeneration (AMD). Spectral-domain optical coherence tomography volumes from 83 eyes (44 patients) with SDDs from the Amish Eye Study were analyzed. A semi-automated deep learning-based segmentation with manual correction delineated the inner EZ, inner RPE, and inner SDD surfaces. Photoreceptor outer segment (POS; EZ-SDD) thickness, SDD thickness, and EZ-RPE thickness were measured within Early Treatment Diabetic Retinopathy Study subfields. The proportional SDD contribution to EZ thickness (SDD/EZ ratio) and longitudinal changes over 2 years were evaluated. Mean POS and EZ-RPE thickness were 24.4 \u00b1 4.3 \u00b5m and 26.3 \u00b1 5.1 \u00b5m, respectively. Mean SDD thickness was 1.95 \u00b1 2.5 \u00b5m, increasing to 6.75 \u00b1 3.9 \u00b5m in SDD-dominant regions. The SDD/EZ ratio averaged 6.9% \u00b1 6.7% and exceeded 10% in 24% of eyes, mainly in the outer macular ring. Over 2 years, POS thickness and EZ-RPE thickness decreased significantly (\u0394POS = -2.59 \u00b5m; \u0394EZ-RPE = -2.86 \u00b5m; P = 0.002, P = 0.006, respectively) with a strong correlation (R2 = 0.79), which weakened in eyes with high SDD burden (R2 = 0.16). SDDs cause variable inflation of EZ-RPE thickness, particularly perifoveally. While EZ-RPE thinning reflects POS loss, its reliability may decrease with substantial SDDs. POS-specific metrics and SDD/EZ ratios may improve EZ-based endpoints in AMD trials.",

Adults aged 60 years or older; 2468 with gradable fundus data or fundus examination were analysed. Self-reported diabetes mellitus (DM), demographics, ocular/systemic history, and lifestyle factors. DR prevalence/severity graded from fundus photographs using a modified Airlie House system; clinically significant macular oedema (CSMO), vision-threatening retinopathy (VTR), and DR risk factors. Among 2468 participants, DR prevalence was 6.9% (170/2468; 95% CI, 6.0%-8.0%). Among 352 participants with self-reported diabetes, 31.0% (109/352; 95% CI, 26.4%-36.0%) had DR; mild, moderate, severe non-proliferative DR, and proliferative DR were observed in 13.6%, 7.1%, 7.4%, and 2.8%, respectively. CSMO and VTR were present in 6.5% and 11.9%, respectively. Increased DR risk was associated with male gender (OR\u2009=\u20092.64), insulin therapy (OR\u2009=\u20094.87), and longer antihyperglycaemic treatment duration (OR\u2009=\u20091.05/year).

Patients with mild to moderate non-proliferative DR were randomized to receive KRG extract or placebo for 90 days. Outcomes included changes in the best-corrected visual acuity (BCVA), intraocular pressure (IOP), central macular thickness (CMT), and optical coherence tomography angiography (OCTA) parameters, including the foveal avascular zone, vessel length density (VLD), and perfusion index (PI) in the superficial and deep capillary plexuses (SCP and DCP, respectively). The incidence of proliferative DR or diabetic macular edema (DME) was also monitored. Twenty-four patients were enrolled and 23 completed the study. The baseline BCVA, IOP, CMT, and OCTA parameters were comparable between the groups (all p\u00a0>\u00a00.05). No significant changes were observed in BCVA, CMT, DR severity stage, or incidence of DME over the 3-month follow-up period in either group.

No significant interaction effects were identified for SCP parameters or other DCP subfields. No adverse events were reported. KRG extract was associated with short-term, region-specific changes in OCTA-derived DCP perfusion metrics over 3 months. These findings reflect alterations in OCTA-derived microvascular parameters and do not establish modification of clinical outcomes such as DR progression or the development of DME.

Although current therapies effectively suppress pathological neovascularization, many patients continue to exhibit persistent visual dysfunction despite regression of active disease, highlighting an unmet need for neuroprotective interventions. Sigma 1 receptor (Sig1R), an endoplasmic reticulum-mitochondrial chaperone and regulator of cellular stress responses, has emerged as a promising therapeutic target in neurodegenerative and retinal diseases. Here, we investigated whether Sig1R activation confers sustained neuroprotection following neonatal ischemic retinal injury. Wild-type and Sig1R knockout mice were subjected to oxygen-induced retinopathy (OIR) and treated systemically with the high-affinity Sig1R agonist (+)-pentazocine [(+)-PTZ]. Retinal structure and visual function were assessed longitudinally through 20 weeks of age using visual acuity, contrast sensitivity, electroretinography (ERG), pattern ERG (PERG), spectral-domain optical coherence tomography (SD-OCT), and histological analyses. Chronic Sig1R activation significantly preserved visual acuity, contrast sensitivity, rod- and ganglion cell-mediated retinal function, retinal ganglion cell survival, and inner retinal architecture in OIR mice. These protective effects were abolished in Sig1R-deficient mice, demonstrating a requirement for Sig1R in mediating neuroprotection. Mechanistically, Sig1R activation reduced apoptotic signaling, attenuated oxidative and nitrosative stress, improved mitochondrial respiratory function, and enhanced endogenous antioxidant pathways. Collectively, these findings demonstrate that Sig1R activation provides durable, receptor-dependent neuroprotection following neonatal ischemic retinal injury by coordinating redox, mitochondrial, and cell-survival pathways. These results identify Sig1R as a promising therapeutic target for preserving retinal neuronal integrity and long-term visual function in retinopathy of prematurity.",

Optical coherence tomography angiography (OCTA) quantifies retinal perfusion, but its prognostic value in referable DR is not fully established. We aimed to validate baseline deep capillary plexus (DCP) OCTA metrics for predicting one-year complications in eyes with referable DR. In this prospective longitudinal study in 137 eyes of 96 participants, we assessed baseline predictors of DR complications, defined as best-corrected visual acuity (BCVA) loss (\u2265 10 letters on the ETDRS chart), center-involving diabetic macular edema, anti-VEGF injections, pan-retinal photocoagulation, or vitreous hemorrhage. Baseline variables included BCVA, low-luminance visual acuity (LLVA), ocular parameters, demographic characteristics, systemic variables, and OCTA metrics (foveal avascular zone area, vessel density [VD] and geometric perfusion deficit in the superficial capillary plexuses [SCP] and [DCP]). Logistic regression prioritized variables with pathophysiologic relevance while minimizing risk of collinearity. Receiver operating characteristic (ROC) curves assessed whether DCP OCTA metrics improved discrimination beyond a clinical model with traditional risk factors. Over one year, 34 eyes (24.8%) experienced one or more complications. Multivariate analysis including DR severity, DCP VD, and LLVA identified higher baseline DR severity (OR, 5.77; 95% CI: 1.93 to 17.27; P = 0.002) and lower DCP VD (OR, 0.59; 95% CI: 0.36 to 0.95; P = 0.031) as significant predictors. Adding DCP VD to the clinical model significantly improved discrimination. These findings support DCP OCTA metrics as capillary-level biomarkers for risk stratification in referable DR and highlight the need for larger longitudinal studies to confirm clinical utility.",

This study aimed to untangle the critical role and mechanism of mitochondrial fission in this process. We found that under HG conditions, the level of p-Drp1 was significantly elevated (P\u2009<\u20090.05), driving excessive mitochondrial fission. Functional experiments confirmed that artificially enhancing mitochondrial fission directly inhibited the Hippo signaling pathway (levels of core proteins p-MST1/2, p-LATS1, and p-YAP decreased, P\u2009<\u20090.05, and YAP translocated to the nucleus), thereby activating M\u00fcller cells (expression of marker proteins GS and Kir4.1 decreased, while expression of GFAP, AQP4, and inflammatory mediators IL-1\u03b2, IL-6, VEGF increased, P\u2009<\u20090.05). Key rescue experiments demonstrated that Drp1 silencing (reduced p-Drp1 level, P\u2009<\u20090.05) reversed the aforementioned activation; however, co-administration of the Hippo pathway inhibitor XMU-MP-1 re-induced cell activation, proving that the Hippo pathway is a necessary downstream mediator of mitochondrial fission. In a diabetic rat model, elevated p-Drp1, Hippo pathway inhibition, and cell activation were similarly observed; the mitochondrial fission inhibitor Mdivi-1 alleviated this pathological process, whereas XMU-MP-1 counteracted its protective effects. This study systematically elucidates, from ex vivo to in vivo, the causal regulatory axis of \"HG- mitochondrial fission- Hippo pathway inhibition-M\u00fcller cell activation,\" providing experimental evidence and a potential target for developing DR-targeted therapeutic strategies centered on intervening in mitochondrial dynamics.",

Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment.",

Sixty-three eyes of 56 patients with PDR were retrospectively studied. Patients with very severe proliferation were excluded in this study. Twenty-six patients (30 eyes) received CPRP and 30 patients (33 eyes) received modified PPRP in PPV. Preoperative and postoperative ophthalmologic examinations were performed. Best corrected visual acuity (BCVA) was performed at baseline and 3\u00a0months after surgery. Central macular thickness (CMT) was measured at 1\u00a0week and 3\u00a0months after surgery. Postoperative inflammation was examined at 1\u00a0day and 3\u00a0months after surgery. Other postoperative complications were also analyzed at 3\u00a0months after surgery. Of all the included eyes, 24 eyes (38.1%) were diagnosed with neovascularization elsewhere (NVE) and/or neovascularization of the disc (NVD) and 39 eyes (61.9%) were diagnosed with tractional retinal detachment (TRD) preoperatively. The number of laser spots in the CPRP group ranged from 858 to 2245, with an average of 1232 (1048,1369) spots. The number of laser spots in the PPRP group ranged from 394 to 992, with an average of 673 (579, 798) spots. The mean logMAR BCVA before surgery was 1.71\u2009\u00b1\u20090.57 in the CPRP group and 1.57\u2009\u00b1\u20090.64 in the modified PPRP group, with no statistical difference between the two groups (P\u2009=\u20090.476). The mean logMAR BCVA was 1.15\u2009\u00b1\u20090.74 in the CPRP group and 0.77\u2009\u00b1\u20090.54 in the PPRP group at 3\u00a0months after surgery, showing that the PPRP group had more visual acuity improvement than the CPRP group (P\u2009=\u20090.037). There was a significant correlation between BCVA and the number of laser spots (P\u2009=\u20090.006). The difference of CMT between the two groups was statistically significant at 1\u00a0week after surgery (P\u2009=\u20090.02), but not at 3\u00a0months after surgery (P\u2009=\u20090.587).

Such build-up forms A\u03b2 plaques and Tau neurofibrillary tangles, both of which are associated with synaptic loss, cognitive decline, and reduced cerebral blood flow in Alzheimer's disease (AD). Two ion channels in brain capillary endothelial cells (ECs)-the inwardly rectifying potassium channel Kir2.1 and the mechanosensitive channel Piezo1-are critical regulators of cerebral blood flow, and both display impaired activity in AD. Whether A\u03b2 and Tau affect these channels remains incompletely understood. Using patch-clamp electrophysiology and freshly isolated mouse brain capillary ECs, we examined whether A\u03b21-40 or Tau-441 directly modulate Kir2.1 or Piezo1 function. Exogenously applied A\u03b21-40 (10-100 nM) and Tau-441 (10-50 nM) had minimal effect on Kir2.1 current density, indicating that the Kir2.1 deficits observed in AD are less likely caused by direct interactions with A\u03b2 or Tau. In contrast, we previously demonstrated that nanomolar A\u03b21-40 enhanced Piezo1 function. We further show here that 50 nM Tau-441 significantly increased Piezo1 open probability, and this enhancement was abolished by the superoxide dismutase and catalase mimetic EUK-134. These data collectively suggest that altered Piezo1 function in neurodegenerative disease could involve a direct effect of A\u03b2 peptides or Tau proteins and further suggest that acute exposure to these proteins minimally impacts Kir2.1 activity. These novel findings present a new pathway through which Tau proteins could impair neurovascular function during neurodegeneration.",

Despite contemporary treatments, many patients still experience disease progression, with some ultimately losing vision. The purpose of this review is to demonstrate how derangements in mitochondrial biology underpin the pathophysiology of glaucoma, and to explore emerging therapeutic options. Literature searches were performed using multiple databases, aiming to identify recent developments in the scientific knowledge surrounding mitochondrial biology and glaucoma. Key words used in the primary literature search included combinations of \"glaucoma\", \"mitochondria\", \"oxidative stress\", \"metabolism\", \"inflammation\", \"transport\" and \"genetics\". Additional database searches were performed to further explore specific details identified in the primary search. Recent research points to mitochondrial insufficiencies as a primary culprit in the pathophysiology of glaucoma. Dysfunction of mitochondria occurs in a multitude of ways, and is an integral component of neuroinflammation, metabolic compromise, and disruption of axonal transport. This in part results from accumulated genetic factors, leading to generation of superoxides that damage retinal ganglion cells resulting in neurodegeneration of the optic nerve. Defects in mitochondrial biology among a range of ocular cell types contribute to the progression of glaucoma. With this understanding, emerging treatments targeting mitochondria, including gene therapies, tunneling nanotubules, and pharmacotherapeutics which enhance mitochondrial function and reduce oxidative stress, are likely the future of glaucoma management. By targeting mitochondrial insufficiencies as a root cause of glaucoma in addition to managing intraocular pressure, this new approach offers hope for preventing vision loss and potentially curing glaucoma.",

Registry.\nAbstract: We evaluated 24-month real-world outcomes of intravitreal aflibercept 2\u00a0mg for diabetic macular edema (DME) in treatment-naive eyes and eyes previously treated with macular thermal laser photocoagulation. This retrospective observational cohort study analyzed data from a prospectively designed treatment outcomes registry. We described outcomes separately in treatment-naive eyes and eyes previously treated with macular thermal laser photocoagulation, all of which received intravitreal aflibercept 2\u00a0mg for DME in routine clinical practice. Given the small number of eyes with prior macular laser, findings in this subgroup were considered descriptive and exploratory. The main functional outcome was change in visual acuity (VA) from baseline at 6, 12, and 24\u00a0months. The main anatomical outcome was change in central subfield thickness (CST) from baseline at the same time points. Secondary outcomes were injection and visit burden, changes in center-involving clinically significant macular edema activity, time to additional macular laser treatment, and ocular adverse events. The cohort included 122 eyes from 78 patients: 110 treatment-naive eyes and 12 eyes with prior macular laser. In treatment-naive eyes, mean VA improved from baseline by 5.5, 5.0, and 5.5 letters at 6, 12, and 24\u00a0months, respectively. Mean CST decreased by 105.9\u00a0\u00b5m, 90.4\u00a0\u00b5m, and 97.1\u00a0\u00b5m, respectively. In eyes with prior macular laser, changes in VA were not statistically significant at any follow-up point. CST decreased significantly at 6\u00a0months (-36.5\u00a0\u00b5m) and 12\u00a0months (-37.5\u00a0\u00b5m), but not at 24\u00a0months (-26.1\u00a0\u00b5m). By month 24, the median number of injections was 12 in treatment-naive eyes and 11 in eyes with prior macular laser. Additional macular laser was rarely needed, and ocular adverse events were rare. In routine clinical care, intravitreal aflibercept 2\u00a0mg for DME was associated with sustained anatomical improvement and modest, largely stable visual gains over 24\u00a0months, particularly in treatment-naive eyes. These findings support favorable real-world outcomes with aflibercept, although subgroup findings in eyes with prior macular laser should be interpreted cautiously.",

Individuals with multiple sclerosis show reduced PA levels, and open-label data have suggested beneficial immunomodulatory and clinical effects of supplementation. The Multiple sclerosis And DisAbility Improvement (MADAI) trial was a randomized, double-blind, placebo-controlled, single-centre, phase 2b study designed to evaluate the efficacy and safety of PA as an add-on therapy in adults with clinically stable multiple sclerosis. Between April 5 and 29 May 2024, 101 adults (64% women; mean age 45 years) were randomly assigned in a 2:1 ratio to receive PA 500\u2005mg twice daily or matching placebo for 90 days. The primary outcome was the change in serum neurofilament light chain (sNfL) concentration, a biomarker of neuroaxonal damage, adjusted for age, body mass index, creatinine, and baseline sNfL. Secondary outcomes included physical and cognitive performance measures and patient-reported outcomes, including fatigue and quality of life scores. sNfL levels were significantly reduced in the PA group {-17.9%; from 9.77\u2005pg/ml [95% confidence interval (CI) 9.00 to 10.60] to 8.02\u2005pg/ml (95% CI 7.36 to 8.73); mean difference 1.75\u2005pg/ml (95% CI 0.9 to 2.6); P = 0.000025}, while no significant change was observed in the placebo group. The adjusted mean difference in sNfL levels between the PA and placebo groups at follow-up was 0.91\u2005pg/ml (95% CI 0.02 to 1.79; P = 0.045). Reductions in sNfL were also observed among participants in the PA arm receiving moderate-to-high efficacy disease-modifying therapies (n = 41; P = 0.0001), including those on anti-CD20 treatment (n = 27; P = 0.0005). There was a trend towards improvement in motor fatigue in the PA group. No serious adverse events related to the study medication occurred. PA supplementation was well tolerated and associated with significant reductions in sNfL, suggesting attenuation of neuroaxonal injury in multiple sclerosis. These findings support further evaluation of PA as an add-on treatment in larger, long-term studies.",

In Australia, islet cell transplantation (ICT) is available for adults with T1D experiencing recurrent severe hypoglycemia. Rapid improvement in glycemia, which can occur post-ICT, may lead to \"early worsening\" of DR and warrants investigation. This study explored eye health outcomes among ICT recipients. This retrospective study examined all ICT recipients at a single tertiary institution in Victoria, Australia, 2007-2022 inclusive. Recipients of successful ICT, with available eye health information pre- and posttransplantation, were included. Eye health outcomes were assessed relative to ICT for changes in DR and other major retinal pathologies. Sixteen recipients (30 eyes) with T1D duration median 31 y (interquartile range, 26-44) were followed up for 5 y (interquartile range, 4-9). At 12 mo post-ICT, hemoglobin A1c improved by -1.2 percentage points (-1.9 to -0.5; P\u2005<\u20050.001). Pre-ICT, 9 of 16 recipients (56%) had DR, with 4 recipients having proliferative DR. During follow-up post-ICT, 4 of 16 recipients (25%) had worsening eye outcomes; there were no new cases of proliferative DR. Four recipients had \"early worsening\" signs, not associated with progression of DR. Recipients experiencing worsening eye outcomes post-ICT exhibited higher hemoglobin A1c and lower C-peptide levels during 12 mo compared with recipients who had stable eye outcomes (P\u2005=\u20050.02 and P\u2005=\u20050.01, respectively). These findings highlight the potential positive impact of ICT to stabilize eye health among a small group of ICT recipients with long-duration type 1 diabetes. An extended systematic evaluation of eye health pre- and post-ICT is required to monitor both short-term and long-term eye health among transplant recipients.",

Emerging evidence indicates that PANoptosis, an integrated inflammatory programmed cell death modality encompassing apoptosis, pyroptosis, and necroptosis, participates in the progression of diabetic retinal damage; however, the supporting evidence varies substantially across clinical specimens, diabetic animal models, high-glucose cultured retinal cells, and non-DR inflammatory disease models. This review systematically summarizes the latest advances in PANoptosis-associated mechanisms underlying DR pathogenesis, focusing on PANoptosome signaling networks, non-coding RNA-mediated regulation, and immune-metabolic crosstalk. We outline promising candidate biomarkers including PANoptosis-related gene signatures and inflammatory cell death molecules, and critically evaluate multiple translational therapeutic strategies covering small-molecule inhibitors, gene intervention, and nanomedicine delivery. Importantly, we further address context-dependent dual roles of PANoptosis, potential safety risks of non-selective PANoptosis blockade, challenges in blood-retinal barrier penetration, systemic immune side effects, and pathological heterogeneity among DR subtypes and disease stages. Since PANoptosis also fundamentally contributes to host defense and retinal innate immune homeostasis, DR therapeutic strategies should prioritize biomarker-guided, local ocular delivery, time-dependent stage intervention, and cell-type-specific fine tuning, rather than generalized systemic suppression. By reconciling mechanistic progress with unresolved translational bottlenecks, this review proposes that PANoptosis serves as a dynamic and evolving conceptual framework for interpreting inflammatory neurovascular degeneration in DR, instead of an entirely confirmed clinical therapeutic target. We emphasize the urgent need for DR-specific mechanistic verification, longitudinal biomarker cohort studies, and well-designed multicenter clinical trials to advance safe and precise targeted interventions.",
        "42405673": "ID: 42405673\nTitle: The Molecular Basis of Ocular Aging: Mechanisms, Pathologies, and Emerging Therapeutics.\nAbstract: Age-related eye diseases (AREDs)-including age-related macular degeneration (AMD), glaucoma, and diabetic retinopathy-are leading causes of permanent blindness. Current treatments manage clinical manifestations but do not halt the molecular processes that drive disease progression. This limitation has shifted attention toward \"geroscience,\" a strategy that targets the fundamental biology of aging rather than treating each disease in isolation. Four key hallmarks of aging-mitochondrial dysfunction, loss of proteostasis, cellular senescence, and epigenetic drift-are widely implicated in AREDs. We review evidence that these hallmarks do not act independently; instead, they form an interactive, self-reinforcing network. The way this network engages differs from tissue to tissue. In the high-energy environment of the retinal pigment epithelium, mitochondrial dysfunction dominates and drives AMD. In the mechanically stressed trabecular meshwork (TM), senescence and epigenetic drift take precedence, leading to glaucoma. In the neurovascular unit, chronic hyperglycemia routes the same network into a metabolic-epigenetic amplification loop that sustains diabetic retinopathy. The same aging mechanisms, routed through distinct tissue contexts, thus produce divergent clinical phenotypes. We also evaluate emerging therapies, including senolytics, mitochondria-targeted agents, and partial epigenetic reprogramming, and identify key intervention nodes such as NLRP3, p62, and NAD\u207a metabolism. Dismantling these pathological feedback loops offers a path beyond symptom management toward combination strategies that restore tissue resilience.",

We investigated the role of microglial protein-tyrosine phosphatase 1B (PTP1B) as a potential driver of neuropathology in chronic toxoplasmosis. Using a murine model, we demonstrate that PTP1B expression is elevated in the hippocampus following infection. Global genetic ablation or pharmacological inhibition of PTP1B rescued infection-induced cognitive deficits and mitigated neuroinflammation. Crucially, microglia-specific deletion of Ptp1b prevented synaptic loss and cognitive impairment. Mechanistically, we show that microglial PTP1B potentiates the nuclear factor-kappa B (NF-\u03baB) pathway, promoting complement component 1q (C1q)-mediated synaptic tagging and subsequent neuronal structural damage. Validating the clinical relevance of these findings, we observed significantly elevated PTP1B levels in peripheral blood mononuclear cells from T. gondii-seropositive individuals, which correlated with inflammatory markers. Overall, our findings identify microglial PTP1B as a pivotal mediator of T. gondii-associated neurodegeneration.",

Because the retina and kidney share similar microvascular architecture, renal dysfunction-routinely expressed as the estimated glomerular filtration rate (eGFR)-is biologically plausible as a marker of DR risk. However, the relationship between eGFR and DR remains controversial. This study aimed to investigate the association between eGFR and DR prevalence in diabetic patients with type 2 diabetes mellitus. This study represents a secondary analysis of data derived from a cross-sectional study. We included 2001 adults with diabetes mellitus (858 men and 1143 women; mean age 64.0\u2009\u00b1\u200911.3 years) who attended the internal-medicine outpatient clinics of two hospitals in southern Taiwan between April 2002 and November 2004. Demographic and clinical variables were recorded, and eGFR was calculated using the simplified MDRD equation. The association between eGFR and DR was examined with multivariable logistic regression, adjusting for potential confounders. To explore potential non-linear relationships, we further applied a generalized additive model (GAM) with smooth-spline fitting. Higher eGFR was inversely associated with the odds of DR across progressively adjusted models. When modeled as a continuous variable, higher eGFR was linked to lower DR odds in Model 1 (OR 0.88; 95% CI 0.83-0.92; P\u2009<\u20090.0001), Model 2 (OR 0.90; 95% CI 0.85-0.95; P\u2009<\u20090.0001), and remained significant after full adjustment in Model 3 (OR 0.92; 95% CI 0.87-0.98; P\u2009=\u20090.0056), indicating a robust inverse association. Compared with the lowest eGFR tertile (15.36-60.50 mL/min/1.73 m2), the highest tertile (76.68-141.22 mL/min/1.73 m2) showed a 30% lower risk of DR (adjusted OR 0.70, 95% CI 0.50-0.90). Smooth-spline analysis confirmed a linear inverse relationship, and no significant effect modification was observed across subgroups of age, sex, BMI, blood pressure, glycaemic control or cardiovascular comorbidities. This cross-sectional analysis demonstrates a clear dose-response pattern: each incremental increase in estimated glomerular filtration rate (eGFR) is associated with a proportional reduction in the likelihood of diabetic retinopathy among adults with type 2 diabetes mellitus. Future work should dissect the shared microvascular pathways linking the kidney and retina and determine whether interventions that preserve renal function can translate into meaningful reductions in retinopathy risk.",
        "42410910": "ID: 42410910\nTitle: Targeting the SNAI1-LAMP3 axis to restore lysosomal function and alleviate autophagic flux impairment to delay retinal degeneration.\nAbstract: Retinal degenerative diseases are a leading cause of irreversible blindness. Their pathogenesis is intricately linked to oxidative stress-induced dysfunction of retinal pigment epithelial (RPE) cells and subsequent retinal degeneration. Macroautophagy/autophagy, a critical cellular degradation pathway, plays a vital role in maintaining RPE homeostasis, yet its dysregulation in retinal degenerative diseases remains poorly understood. In this study, we observed that sodium iodate (NaIO3), an oxidative stress inducer, triggered lysosomal dysfunction via lysosomal membrane permeabilization (LMP), thereby impairing autophagic flux in RPE cells and exacerbating retinal degeneration. RNA sequencing identified LAMP3 (lysosomal-associated membrane protein 3) as a downregulated gene following NaIO3 treatment. Functionally, LAMP3 overexpression alleviated NaIO3-induced LMP, improved lysosomal function, and alleviated autophagic impairment. Furthermore, upregulation of LAMP3 reduced oxidative stress and apoptosis in RPE cells, while alleviating retinal degeneration in a NaIO3-induced mouse model. Mechanistically, our data suggested that NaIO3 upregulated the transcription factor SNAI1, which acts as a transcriptional repressor of LAMP3. SNAI1 knockdown increased LAMP3 expression, thereby facilitating the recovery of lysosomal function and the alleviation of autophagic impairment. Collectively, our findings indicate that the SNAI1-LAMP3 axis contributes to the regulation of the autophagy-lysosomal pathway in retinal degeneration, highlighting a potential therapeutic target for delaying disease progression.Abbreviations: AMD: age-related macular degeneration; AO: acridine orange; Baf A1: bafilomycin A1; BAX: BCL2-associated X protein; BCL2: B cell leukemia/lymphoma 2; BSA: bovine serum albumin; CCK-8: cell counting kit-8; ChIP: chromatin immunoprecipitation; CM-H2DCFDA: chloromethyl-2',7'-dichlorodihydrofluorescein diacetate; CTSD: cathepsin D; DAPI: 4',6-diamidino-2-phenylindole; DEGs: differentially expressed genes; DHE: dihydroethidium; EdU: 5-ethynyl-2'-deoxyuridine; ERG: electroretinography; GSEA: gene set enrichment analysis; H&E: hematoxylin and eosin; HsRPE: human primary retinal pigment epithelial; JC-1: 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolylcarbocyanine iodide; LAMP1: lysosomal-associated membrane protein 1; LAMP2: lysosomal-associated membrane protein 2; LAMP3: lysosomal-associated membrane protein 3; LGALS3: lectin, galactose binding, soluble 3; LLOMe: leu-leu methyl ester; LMP: lysosomal membrane permeabilization; MAP1LC3B/LC3B: microtubule-associated protein 1 light chain 3 beta; MMP: mitochondrial membrane potential; NAC: N-acetyl-L-cysteine; NaIO3: sodium iodte; NC: negative control; OCT: optical coherence tomography; PCA: principal component analysis; PI: propidium iodide; qRT-PCR: quantitative real-time polymerase chain reaction; Rapa: rapamycin; ROS: reactive oxygen species; RP: retinitis pigmentosa; RPE: retinal pigment epithelium; RPE65: retinal pigment epithelium 65; siRNA: small interfering RNA; SNAI1: snail family zinc finger 1; SQSTM1/p62: sequestosome 1; TJP1/ZO-1: tight junction protein 1; ZNF135: zinc finger protein 135.",

While mesenchymal stem cells (MSCs) hold therapeutic potential for various conditions, their clinical utility is constrained by challenges in sourcing and limited availability. This study investigated a novel therapeutic approach using trophoblast-derived mesenchymal-like stem cells (T-MSCs), which can be stably generated from commercially available embryonic stem cells, and the small extracellular vesicles (T-MSCs-sEVs) that they secrete. We explored the therapeutic effects against PD by inhibiting Caspase-8/Caspase-3-mediated apoptosis both in vitro and in vivo using experimental assays (e.g., flow cytometry (FCM) analysis, western blotting, and immunofluorescence staining). The selected cytokine Clusterin was validated via G-Series Mouse Cytokine Antibody Array 4000 (GSM-CAA-4000) using ELISA kits, which revealed its involvement in apoptosis during the PD process. Moreover, T-MSCs and T-MSCs-sEVs could alleviate dopaminergic (DA) neuron damage in vitro and in vivo by inhibiting the Caspase-8/Caspase-3-mediated apoptotic pathway. The results suggest that T-MSCs-sEVs represent a promising biological candidate for future therapeutic strategies aimed at treating PD.",

However, the mechanism underlying its action is not fully understood. Enhancing the function and frequency of peripheral regulatory T cells (Tregs) may mitigate dopaminergic degeneration. This study investigates the role of Tregs in icariin's neuroprotective effects in a rodent model of PD. PD was induced in mice via stereotactic injection of 6-hydroxydopamine (6-OHDA). Mice underwent pretreatment with saline, icariin, an androgen receptor inhibitor (ARI), or a combination of icariin and ARI. Motor function was assessed in each experimental group, and dopaminergic neuronal injury was evaluated using immunohistochemistry (IHC) staining for tyrosine-hydroxylase (TH) in the substantia nigra (SN) and striatum. IHC was used to quantify CD4+ T-cell infiltration in the SN. Neuroinflammation was assessed through mRNA levels of the pro-inflammatory M1 phenotype of microglia, the anti-inflammatory M2 phenotype of microglia, and the levels of indicated pro-inflammatory cytokines in the SN. The frequency of Tregs among peripheral blood mononuclear cells (PBMCs) was analyzed by flow cytometry, and with Tregs were depleted using PC61 monoclonal antibodies. In vitro androgen receptor (AR) knockdown using shRNA in na\u00efve CD4+ T cells was performed to validate the AR-dependent mechanism. The results revealed that icariin significantly alleviated dopaminergic degeneration. Mechanistically, icariin promotes the expansion of peripheral neuroprotective and immunosuppressive Tregs, thereby restricting CD4+ T cell migration into the SN. This improvement in the inflammatory microenvironment reduced neuroinflammation and mitigated neurodegeneration. However, the neuroprotective and anti-inflammatory effects of icariin were lost when combined with ARI. Additionally, Treg depletion before 6-OHDA injection reversed the positive effects observed in the PD model. Icariin protects against neurodegeneration and neuroinflammation by boosting Tregs expansion in an androgen receptor-dependent manner.",

Sinomenine (Sino), a bioactive alkaloid derived from Sinomenium acutum, exhibits anti-inflammatory and anti-apoptotic activities; however, its molecular targets and mechanisms in AIS remain unclear. This study aimed to identify potential targets and key pathways of Sino and validate its neuroprotective effects in AIS. A combined approach integrating network pharmacology, Mendelian randomization (MR), molecular docking, and in vivo validation was adopted. Potential targets of Sino and ischemic stroke were identified using public databases. Overlapping targets were analyzed through protein-protein interaction network construction and Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. Sprague-Dawley rats were randomly assigned to four groups, and a middle cerebral artery occlusion/reperfusion (MCAO/R) model was established (n = 12 per group): Sham, MCAO/R, Sino (20 mg/kg), and Sino +LY294002 (LY, 10 mg/kg). Sino and Sino + LY were administered intraperitoneally within 6 h after surgery and once daily thereafter for three days. Sham and MCAO groups were given the same amount of physiological saline undergoing the same procedures. Sino was administered intraperitoneally within 6 h after surgery and once daily thereafter for three days. Neurological deficits, infarct volume, neuronal injury, apoptosis, activation of the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) pathway, and inflammatory responses were assessed using behavioral tests, 2,3,5-Triphenyltetrazolium chloride (TTC)/Nissl/Terminal deoxynucleotidyl transferase dUTP Nick End Labeling (TUNEL) staining, Western blotting, immunofluorescence, enzyme-linked immunosorbent assay (ELISA). Twelve overlapping targets between Sino and ischemic stroke were identified, with Akt1 recognized as a central hub. Enrichment analysis highlighted the PI3K/Akt pathway as a critical signaling axis, while MR analysis indicated a nominal association between Akt1 and ischemic stroke. Molecular docking predicted stable binding between Sino and Akt1. In MCAO/R rats, Sino significantly improved neurological function, reduced infarct volumes, attenuated neuronal apoptosis, and increased neuronal survival. Mechanistically, Sino increased the p-PI3K/PI3K and p-Akt/Akt ratios, upregulated Bcl-2 expression, and decreased the expression of Bax, cleaved caspase-3, ionized calcium-binding adapter molecule 1 (Iba1), inducible nitric oxide synthase (iNOS), interleukin-1\u03b2 (IL-1\u03b2), interleukin-6 (IL-6), and tumor necrosis factor-\u03b1 (TNF-\u03b1). These beneficial effects were notably attenuated by LY. This study establishes PI3K/Akt as a functionally necessary mediator of Sino's neuroprotection against cerebral ischemia/reperfusion injury. The incomplete LY reversal indicates multi-target activity, supporting Sino's development as an adjunctive therapeutic candidate for ischemic stroke.",

Many molecules have been investigated for their potential ability to modify hemostasis and blood-brain barrier function in ICH. Vascular endothelial growth factor (VEGF) is highly expressed in some diseases and helps induce angiogenesis. VEGF serves as a key mediator of the angiogenic pathway and is now recognized as a major contributor to cerebrovascular diseases; many promising results have been obtained in animal therapeutic experiments. VEGF promotes blood vessel growth (angiogenesis) to increase oxygen and nutrient supply in damaged tissues, and exerts neuroprotective effects in processes including inflammation, apoptosis, neurotrophy, and protein clearance.

Currently, retinal neurodegeneration is regarded as an important feature of diabetic retinopathy (DR). The objective of this study was to investigate the neuroprotective effect of DAla2-GIP-Glu-PAL on diabetic retinopathy (DR), and its possible mechanisms, including regulation of microglia activation, inflammatory response, and oxidative stress. In this study, Type 2 diabetic db/db mice and wild-type (WT) mice were used. The morphology and structure of the retina and the ganglion cell layer were observed using histological methods. The levels of PSD95, IL-1\u03b2, IL-18, pNrf2, HO-1, MDA, SOD, NF-\u03baBp65, NLRP3, Cleaved-Caspase-1, and GSDMD were detected to evaluate retinal oxidative stress and neuroinflammation, and to observe the changes in levels of these indicators after the intravitreal injection of DAla2-GIP-Glu-PAL. The findings demonstrated that db/db mice exhibited significant retinal pathological changes, loss of ganglion cells, decreased synaptic transmission function, and excessive activation of microglia. In addition, the levels of NF-\u03baBp65, NLRP3, Cleaved-Caspase-1, GSDMD, L-1\u03b2, IL-18, and MDA increased, while the levels of pNrf2, HO-1, and SOD decreased. DAla2-GIP-Glu-PAL reversed the excessive activation of microglia and the expression of indicators related to inflammatory responses and oxidative stress, promoting the recovery of retinal neural structure and function.These results imply that DAla2-GIP-Glu-PAL exerted a neuroprotective effect on diabetic retinopathy in mice by inhibiting excessive activation of microglia, inflammatory response, and oxidative stress. Its underlying mechanisms may involve downregulating the NF-\u03baB/NLRP3 pathway and upregulating the Nrf2/HO-1 pathway.",

This review updates the 2004 compilation by Dardonville and Rozas on IR ligands, emphasizing promising ligands, subtype selectivity, and pharmacological profiling. Representative ligands for each subtype are analyzed to highlight key pharmacological aspects, including affinity, selectivity, and functional activity, integrating findings from preclinical and clinical studies. Critical molecular targets such as Nischarin/IRAS for I1R and MAO-B-associated sites for I2R are discussed in the context of ligand design and CNS penetration. I1R-selective ligands, exemplified by rilmenidine, show improved selectivity over \u03b12-adrenoceptors and exhibit antihypertensive, metabolic, and neuroprotective effects. I2R ligands display neuroprotective, anti-inflammatory, and analgesic activities, with CR4056 progressing to Phase II trials.

Behavioral tests, including NOR, MWM, and Y-maze, were conducted to assess cognitive function, followed by biochemical and immunofluorescence analyses. AA restored the BDNF/TrkB/Akt signaling axis disrupted by D-gal administration. Furthermore, immunoblotting for Nrf-2 and HO-1 revealed elevated expression in the mouse cortex and hippocampus. AA also enhanced antioxidant enzymes, including glutathione (GSH), glutathione S-transferase (GST), catalase (CAT), and superoxide dismutase (SOD), while reducing lipid peroxidation (LPO), thereby supporting its antioxidant role. Moreover, D-gal enhanced NF-kB-mediated neuroinflammation, apoptotic markers including caspase-3 and PARP-1, and suppressed synaptic proteins (SNAP-23 and PSD-95). Interestingly, these expression aberrations were reversed upon AA administration. Histological analyses using Nissl and Fluoro-Jade B staining further supported neuronal protection in the cortex and hippocampus. Collectively, these findings suggest that AA exerts neuroprotective effects against D-gal-induced aging and cognitive decline by reducing oxidative stress, neuroinflammation, neuronal apoptosis, and enhancing synaptic plasticity through BDNF/TrkB/Akt/CREB signaling.",

The limitations of current therapeutic modalities highlight the pressing need for continued innovation in therapeutic interventions. This review comprehensively delineated the knowledge architecture, research focal points, and emerging directions in DR therapeutics. Targeted biological agents have recently emerged as principal research directions in DR therapy and hold substantial promise. They are expected to achieve the goals of blocking disease progression more persistently, effectively, and less invasively than nonbiological therapeutics through multitarget synergy and long-acting sustained-release formulations. In clinical practice, the paradigm of DR therapy has shifted toward personalized and precision medicine, with optimized subthreshold micropulse laser as a promising adjunctive therapy for enhancing long-term treatment outcomes. Looking ahead, therapeutic monitoring in DR may evolve beyond conventional morphological grading to incorporate multimodal precision diagnostics, artificial intelligence-driven broad-spectrum screening, and biomarker-based early warning systems. This review concludes with a discussion on prospects and challenges in DR therapeutics, with special emphasis on emerging drug candidates, recent clinical trial findings, and novel insights that may inform the next generation of therapeutic interventions for DR.",

Beyond glycemic control, accumulating experimental and clinical evidence suggests that GLP-1RAs exert pleiotropic actions relevant to neurological diseases. Metabolic dysfunction, chronic inflammation, oxidative stress, mitochondrial impairment, and neurovascular injury represent convergent mechanisms that contribute to neurodegeneration, cerebrovascular pathology, and metabolism-related brain disorders. Notably, these processes overlap with pathways modulated by GLP-1 signaling across systemic and central compartments. GLP-1 receptors are expressed in neurons, glial cells, and components of the neurovascular unit, providing a biological basis for possible neurological effects. Preclinical studies suggest that GLP-1RAs can reduce neuroinflammation and oxidative stress, support mitochondrial function, and help maintain blood-brain barrier integrity. Clinical findings, however, remain inconsistent. Studies in Parkinson's disease have reported encouraging signals, but biomarker evidence for disease modification is still limited. In Alzheimer's disease, clinical trials have produced mixed or negative results. These differences may reflect disease stage, patient selection, drug-specific pharmacology, central nervous system exposure, endpoint sensitivity, and treatment duration. Overall, GLP-1RAs may influence neurological disease through metabolic, inflammatory, and vascular pathways, but their clinical role remains unsettled. Future studies should use biomarker-informed designs, prespecified neurological endpoints, appropriate drug selection, and sufficiently long follow-up to determine which patients and disease stages are most likely to benefit.",

Combining SO removal (SOR) with cataract surgery in a single procedure may improve patient convenience and outcomes. This study aims to evaluate the early postoperative outcomes of phacoemulsification with concurrent SOR in a tertiary eye care hospital of Bangladesh. \u00a0This prospective longitudinal study was conducted at Ispahani Islamia Eye Institute and Hospital, Dhaka, Bangladesh, from January 1, 2023, to June 30, 2023. Patients who had previous surgery due to retinal detachment (RD) or advanced diabetic eye disease with SO used as an internal tamponade with postoperative cataract formation and an attached retina, confirmed by indirect ophthalmoscopic examination or B scan, depending on media clarity, were included in the study. Phacoemulsification with intraocular lens implantation was performed, followed by SOR using the 23-gauge\u00a0pars plana method. Postoperative follow-ups were conducted at day 1, day 7, and at least after 1 month to record visual acuity, complications, and retinal status. \u00a0Out of 42 patients, a majority of patients (13, 31.0%) belonged to the age group of 50-59 years with a mean age of 44.38 \u00b1 14.4 years. The male-to-female ratio was 4:3. The primary pathology was tractional RD secondary to diabetic retinopathy in 24 eyes and rhegmatogenous RD in 18 eyes. There was an improvement in at least one-third of patients' visual acuity postoperatively as recorded by the Snellen chart. Retina was attached in 41 (97.6%) patients, while 1 (2.4%) patient had a redetached retina at the last follow-up. \u00a0Phacoemulsification with concurrent SOR is a useful method that is associated with acceptable visual and anatomical outcomes, and it eliminates the burden for another surgery for cataract extraction.",

This manuscript explores the pivotal role of autophagy impairment in AD pathogenesis, with a specific focus on the AMPK/mTOR signaling axis as a primary regulatory pathway. Findings revealed that while mTOR overactivation suppresses autophagic flux and promotes the buildup of toxic protein aggregates, the activation of AMPK serves to restore homeostatic degradation processes. The review highlights that various pharmacological agent including rapamycin, metformin, trehalose, and curcumin, as well as repurposed drugs like lithium and statins can effectively enhance autophagy to ameliorate cognitive decline and neuroinflammation. Furthermore, herbal formulations such as Danggui Shaoyao San and phytoconstituents like Icariin demonstrate significant neuroprotective potential by modulating these same molecular pathways. Targeting autophagy represents a translationally viable approach for combating AD progression, with drug repurposing offering a time-efficient and cost-effective strategy. To advance these findings, future research should prioritize large-scale clinical trials to validate the efficacy of autophagy-inducing agents in human subjects. Additionally, investigating synergistic combinations of traditional bioactives with synthetic drugs and utilizing innovative delivery systems, such as intranasal nanotechnology-based platforms to bypass the blood-brain barrier, represents a promising frontier for developing effective, multi-targeted treatments against AD.",

Similarly, physical exercise is a consolidated strategy on the prevention of cognitive deficits. Based on the systematic review conducted by Joseph et al. (2023), a study protocol was developed to ensure the combined effect of C. caudatus supplementation and exercise provided improvement against cognitive impairment. There are limitations on studies looking at combined effect of flavonoid and exercise where either one of the interventions provided improvement to the behavioural tests and biomarkers assessed but not when given in combination. Moreover, to our understanding, in the last five years there has been limited research done on the combined effect of flavonoid and exercise against cognitive impairment (based on Pubmed search on 10 June 24; ScienceDirect search on 10 June 24). Therefore, we elucidated a study protocol that looks at the combined effect of C. caudatus supplementation and exercise against AlCl3-induced cognitive impairment in rats and the possible mechanisms involved in its neuroprotective effects in male rats. Male Wistar rats will be divided into different groups: control, physical exercise (treadmill running), supplemented with C. caudatus or in combination. Consequently, neurobehavioural tests (novel object recognition test, open field test & Y-maze), biochemical tests and histology assessment will be determined to unravel the possible neuroprotective capability against AlCl3-induced neurotoxicity. The duration of exercise training is four weeks while C. caudatus is supplemented for 21 days. The primary outcomes will be neurobehaviour changes at baseline, after 21 days of AlCl3-induced rats and at the end of intervention. While the secondary outcomes will be biochemical profile (Oxidative stress markers, inflammatory markers) and brain histology of AlCl3-induced rats. Combining exercise training with C. caudatus supplementation will produce synergistic effects, leading to significant improvements in spatial memory impairment and oxidative stress. This combined approach is expected to be more effective than using either intervention alone, potentially restoring spatial memory and antioxidant levels to normal. Consequently, the findings of this study could hold significant value for aging adults, providing safe and cost-effective strategies for managing neurodegenerative disorders.",

Accumulating evidence indicates that mitochondrial abnormalities, including excessive reactive oxygen species (ROS) production, mitochondrial fragmentation, and inflammatory signaling, play a central role in AMD pathogenesis. In this study, we investigated the therapeutic potential of exogenous mitochondrial transplantation using a sodium iodate (SI)-induced retinal degeneration model that recapitulates key pathological features of dry AMD. In ARPE-19 cells, SI-induced oxidative stress triggered mitochondrial fragmentation, inflammasome activation, and tight junction disruption, whereas delivery of mitochondria isolated from bone marrow-derived mesenchymal stem cells attenuated mitochondrial dysfunction and preserved RPE barrier integrity by suppressing oxidative and inflammatory signaling. Consistent with these in vitro findings, intravitreal mitochondrial transplantation in SI-treated mice attenuated RPE shedding/migration and outer nuclear layer disorganization while suppressing retinal oxidative stress, inflammatory cytokine expression, and complement activation. Importantly, mitochondrial transplantation mitigated the decline in retinal function, as assessed by electroretinography and optokinetic response testing, without fully restoring responses to control levels. Collectively, these results support exogenous mitochondrial transplantation as a promising cell-free therapeutic strategy to attenuate oxidative stress-driven retinal degeneration by modulating mitochondrial dysfunction and associated inflammatory pathways in AMD.",

Soy lecithin contains up to 70% of biologically active phospholipids: phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, and phosphatidic acid. These compounds perform a spectrum of key cellular functions, including neuromediation processes, and ensure formation of the cellular membrane structures and vesicles. Previously, in the mouse model of chronic intestinal inflammation, behavioral changes were observed together with the significant increase in the relative content of several phospholipid classes in the intestinal epithelial cells. The animals fed with soy lecithin, which contains a mixture of these phospholipids, showed similar behavioral changes in the absence of inflammation: impaired social recognition and behavior, reduced signs of compulsivity and anxiety, and increased aggression in males. In this study, we found that reducing the dose of soy lecithin in short-term administration restores normal social recognition and behavior in the healthy C57BL/6 animals, while reduction in anxiety is maintained. Comparative electron microscopy analysis of the neurons and synapses in the amygdala, hypothalamus, and frontal motor cortex of the C57BL/6 animals treated with soy lecithin was conducted. Dose-dependent and region-specific changes were observed. High-dose lecithin administration, both long-term and short-term, reduced synapse density in the neuropil, and irregular synaptic vesicles were detected in the amygdala and hypothalamus. Threefold reduction in the lecithin dosage resulted in the increase in the number of vesicles per synapse in the hypothalamus and motor cortex. The obtained results demonstrate dose-dependent effect of soy lecithin on the synaptic ultrastructure in the hypothalamus, amygdala, and motor cortex of the frontal lobe, as well as on the behavioral patterns of the healthy C57BL/6 laboratory mice.",

The loss of vision caused by diabetes significantly reduces the quality of life and has a major impact on the overall burden of visual impairment. This study assessed the global burden of blindness and visual impairment caused by diabetes among the working population from 1990 to 2021, and predicted the future trends in 2050. Based on data from the Global Burden of Disease Study 2021, we analyzed trends from 1990 to 2021 in the burden of diabetes-related blindness and visual impairment. Key metrics included case numbers and rates of prevalence and years lived with disability (YLDs). Decomposition analysis identified drivers of burden changes, and health inequality analysis assessed disparities by socioeconomic status. We used ARIMA and exponential smoothing models to forecast prevalence and YLDs from 2022 to 2050. From 1990 to 2021, the global burden of blindness and visual impairment caused by diabetes among the working population significantly increased.From 1990 to 2021, the global burden of blindness and visual impairment caused by diabetes among the working population significantly increased. Comparative analysis shows that the number of cases of type 2 diabetes and the number of YLDs are much higher than those of type 1 diabetes. Moreover, the burden on women has always been higher than that on men. Among the working population, blindness and visual impairments caused by diabetes pose a serious and increasingly severe public health threat worldwide, with the impact on women being particularly significant.Among the working population, blindness and visual impairments caused by diabetes pose a serious and increasingly severe public health threat worldwide, with the impact on women being particularly significant.

Diabetic neuropathy is one of the prevalent complications of diabetes, which also includes diabetic nephropathy, retinopathy, cardiomyopathy, and diabetic foot diseases. The present study evaluated the protective effects of Ethiopian coffee beans (Coffea arabica) against glucose-induced brain tissue injury using in\u00a0vitro, ex\u00a0vivo, and in silico experimental models. Oxidative injury was induced by incubating brain tissue collected from normal male Sprague-Dawley rats in glucose solution and treated with the different concentrations of Ethiopian coffee bean extracts (hot and cold aqueous) for 2\u2009h at 37\u00b0C in a 95% O2 and 5% CO2 incubator. Induction of glucose-mediated (0.0111\u2009M glucose) oxidative injury led to significant depletion of reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), and total glycogen levels, while elevating malonaldehyde (MDA), nitric oxide (NO), glycogen phosphorylase, fructose-1,6-bisphosphatase, ATPase, and acetylcholinesterase (AChE) activity levels. Treatment with different concentrations of the aqueous extracts of coffee beans significantly restored the levels and activities of the biomarkers mentioned above. LC-MS analysis indicates the presence of chlorogenic acid (CGA), caffeic acid, quinic acid, caffeine, Cafestol, Kahweol, ferulic acid, and catechol in the coffee extracts. In silico analysis revealed a strong molecular interaction between CGA and the CAT, SOD, and AChE enzymes. The data from this study suggest that bioactive compounds from Coffea arabica have a potential neuroprotective effect against glucose-mediated oxidative neurodegeneration in rat brain tissue.",

Despite advances in acute stroke management, many patients continue to experience substantial neurological disability and incomplete recovery. Minocycline, a tetracycline antibiotic with anti-inflammatory and neuroprotective properties and good blood-brain barrier penetration, has been investigated as a potential adjunctive therapy in AIS. A systematic search of major databases was conducted identifying randomized controlled trials evaluating minocycline in patients with AIS. Outcomes included functional and neurological recovery assessed using the modified Rankin Scale (mRS), National Institutes of Health Stroke Scale (NIHSS), and Barthel index (BI), as well as mortality and vascular events. Pooled effect estimates were calculated using random-effects meta-analysis. Seven RCTs comprising 2197 patients were included, with 1093 receiving minocycline and 1104 receiving placebo or standard care. Functional independence at 3 months (mRS 0-2) showed no significant difference between groups (RR 1.28, 95% CI 0.97-1.69; I2 = 84.9%). Minocycline was associated with lower NIHSS scores (MD -2.45, 95% CI -4.32 to -0.59; I2 = 88.6%) and higher BI scores (MD 12.52, 95% CI 6.28-18.76; I2 = 47.0%). Mortality (RR 0.66, 95% CI 0.39-1.090 and stroke recurrence or MI showed no significant differences (RR 0.97, 95% CI 0.69-1.37). Although a consistent improvement in functional independence was not demonstrated, minocycline showed signals of benefit in selected neurological outcomes with a favorable safety profile. These findings support the need for adequately powered, multicenter randomized trials to clarify its therapeutic role.",

Cistanoside A (Cis A), a bioactive compound derived from Cistanches Herba, exhibits anti-inflammatory, antioxidant, and antiapoptotic effects. Given that these processes are implicated in AD progression, we propose that Cis A may be a promising candidate for AD therapy. We employed an okadaic acid (OA)-induced rat model in vivo and SH-SY5Y cells in vitro. Cognitive function was assessed using the Morris water maze and novel object recognition tests. Hematoxylin and eosin and Nissl staining were performed to evaluate histopathological changes. Neuronal damage was assessed using the Cell Counting Kit-8 assay for cell viability, TUNEL staining for apoptosis, and western blotting for protein expression. Mitochondrial damage was examined using JC-1 and MitoSOX Red staining. Cis A significantly improved cognitive deficits. It attenuated OA-induced apoptosis, restored mitochondrial membrane potential, and reduced reactive oxygen species levels in rats and SH-SY5Y cells by inhibiting hyperphosphorylation of Tau protein via the AKT/GSK3\u03b2 pathway. Furthermore, the protective effect of Cis A was attenuated by MK-2206 and AKT knockdown in vitro.

Although polydatin (PLD) possesses promising biological effects, no major study has yet explored its anti-neurodegenerative efficacy in the hippocampus. This study therefore aims to investigate the probable protective effects of PLD against hippocampal neurodegeneration in diabetic rats, as well as explore its in-silico inhibitory activity against two key enzymes implicated in the progression of AD. Experimental diabetes was induced in male albino rats then PLD was administered orally to the diabetic rats (50\u00a0mg/kg b.wt.) daily for four weeks. In silico molecular docking was used to predict the interactions of PLD against BACE1 and AChE. PLD treatment significantly improved diabetic parameters, lowering blood glucose and raising serum insulin. Excitingly, PLD markedly alleviated oxidative stress by reducing lipid peroxidation and nitric oxide levels while enhancing antioxidant defenses (elevated GPx activity and GSH content) in the hippocampus of diabetic rats. PLD also suppressed neuroinflammation by down-regulating NF-\u03baB, COX-2, and IL-6 mRNA expression. Furthermore, PLD significantly elevated the protein level of IDE while lowered A\u03b21-42 level. In silico, PLD revealed potent binding affinity for BACE1 (-8.6 Kcal/mol) and AChE (-10.5 Kcal/mol), interacting with key residues, indicating its inhibition potential. Overall, PLD effectively reduced neurodegeneration in the hippocampus of diabetic rats via inhibiting oxidative stress, inflammation, and A\u03b21-42 accumulation. PLD may act as a promising multi-target anti-neurodegenerative candidate, capable of simultaneously modulating multiple pathways and more experimental validation are needed in the future.",

However, the mechanisms by which microglia-M\u00fcller cell interactions influence retinal neuroinflammation and neurotrophic support during glaucoma remain unclear. Here, we aimed to identify glia-associated regulatory factors involved in microglia-M\u00fcller cell communication during glaucoma and to determine their contribution to retinal neurodegeneration. A chronic ocular hypertension (COH) mouse model and a conditioned medium (CM)-based inflammatory system were used to investigate microglia-M\u00fcller cell interactions and the role of fibroblast growth factor 1 (FGF1) in retinal neuroinflammation. Sustained intraocular pressure (IOP) elevation induced glial activation and progressive RGC degeneration in COH retinas. Transcriptomic profiling of M\u00fcller cells exposed to microglia-CM identified FGF1 as a significantly downregulated candidate neurotrophic factor, accompanied by enrichment of immune and inflammatory pathways. Functionally, M\u00fcller cell FGF1 deficiency exacerbated, whereas exogenous FGF1 attenuated, inflammation-induced RGC apoptosis in vitro. In vivo, intravitreal rFGF1 reduced RGC apoptosis, preserved RGC survival, and maintained retinal structure without affecting IOP. Consistently, reduced FGF1 expression was observed in M\u00fcller cell-enriched regions of human glaucomatous retinas. Together, these findings suggest that microglia-driven inflammation suppresses M\u00fcller cell FGF1 expression, thereby impairing neurotrophic support and increasing retinal vulnerability during COH. Restoration of FGF1 signaling confers neuroprotection independently of IOP reduction and may represent a promising glia-targeted therapeutic strategy for glaucoma.",
        "42426288": "ID: 42426288\nTitle: The emerging role of circular RNAs in neurodegenerative diseases and viral infections.\nAbstract: Circular RNAs (circRNAs) represent a class of highly stable, covalently closed RNA molecules increasingly recognized as important regulators of brain aging and neurodegenerative disease. Growing evidence also implies circRNAs in viral infection, suggesting a potential intersection between viral neuropathogenesis and neurodegeneration. However, no studies have yet directly integrated circRNAs, neurotropic viral infections, and neurodegenerative disorders within a single mechanistic framework. To date, specific circRNAs have been linked to the progression of Alzheimer's disease and Parkinson's disease, where they regulate central pathological processes including amyloid-\u03b2 clearance, neuroinflammation, synaptic plasticity, neuronal apoptosis, and oxidative stress. Moreover, it has been established that both host cells and viruses produce circRNAs during infection. Virus-derived circRNAs can enhance viral replication, promote immune evasion, and support latency. In contrast, host circRNAs contribute to antiviral defense by acting as microRNA sponges, interacting with viral proteins, or encoding peptides with antiviral activity, mechanisms particularly explored in viral oncogenesis. In this review, we will evaluate the most updated research evidence on the role of circRNAs in major neurodegenerative diseases and neurotropic viral infections. Considering the growing concern regarding the long-term neurological consequences of viral infections, including chronic neuroinflammation, viral reactivation, and post-viral syndromes, dysregulated circRNAs may represent a mechanistic link between viral infection and associated neurodegenerative processes. Finally, we will discuss future directions for identifying circRNAs-based biomarkers and developing circRNAs-targeted therapeutic strategies for age-related and virus-associated neurological disorders.",

The phase III BALATON and COMINO trials demonstrated non-inferiority to aflibercept at week 24, and several real-world cohorts have subsequently emerged. The aim of this systematic review and meta-analysis was to estimate the pooled effect of faricimab on visual acuity, treatment burden, anatomical outcomes, and safety in this indication. PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials were systematically searched from inception to 1 May 2026 for studies reporting outcomes following intravitreal faricimab. Risk of bias was assessed in duplicate using the Cochrane Risk of Bias 2 tool for the randomised evidence and the Risk Of Bias In Non-randomised Studies of Interventions tool for the observational evidence, with single-arm cohorts evaluated as pre-post comparisons. The primary visual acuity outcome was pooled using random-effects meta-analysis with Hartung-Knapp-Sidik-Jonkman adjustment, stratified by treatment status, while outcomes precluded from pooling by methodological heterogeneity were synthesised narratively. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation framework. Ten studies comprising 1,620 eyes met eligibility criteria, including the BALATON and COMINO randomised controlled trials and nine non-randomised cohorts. The pooled mean change in best-corrected visual acuity at approximately 6 months was +\u200916.89 Early Treatment Diabetic Retinopathy Study letters (95% confidence interval 16.05 to 17.72) in treatment-na\u00efve eyes and +\u20098.73 letters (95% confidence interval 4.75 to 12.71) in refractory switch cohorts, with negligible between-study heterogeneity in both analyses. Narrative synthesis was consistent with treatment interval extension following initiation of or switch to faricimab, statistically significant reductions in central retinal thickness across studies, and a short-term safety profile without identified retinal vasculitis events. The synthesis is consistent with intravitreal faricimab use being associated with visual and anatomical improvement in macular oedema secondary to retinal vein occlusion, with the treatment-na\u00efve pooled estimate primarily reflecting registration trial data and the switch cohort estimate characterising refractory phenotypes.",

Aflibercept is a standard treatment of DME; however, the benefit of combining it with laser therapy remains uncertain. A systematic review of randomized controlled trials (RCTs) comparing aflibercept alone with a combination of aflibercept plus laser therapy for management of DME was conducted. PubMed, Cochrane Library, and Embase were searched according to PRISMA guidelines. Primary outcomes were best corrected visual acuity (BCVA) and central macular thickness (CMT), while secondary outcome was treatment burden. Six RCTs involving 275 patients were included. At 12\u2009months, combination therapy yielded a modest improvement in BCVA (mean difference [MD]\u2009=\u20090.18; 95% CI: -0.17 to 0.52; p\u2009=\u20090.32) and a minor reduction in CMT (MD\u2009=\u20090.13\u2009\u03bcm; 95% CI: -0.13 to 0.39; p\u2009=\u20090.32). The number of aflibercept injections was slightly lower in the combination group (MD = -0.53 injections; 95% CI: -1.23 to 0.17; p = 0.14). The adjunctive use of laser therapy with aflibercept in DME does not provide statistically significant improvement in visual or anatomical outcomes over aflibercept alone. Diabetic macular edema (DME) is a common eye disease in diabetic patients, causing blurred vision and even vision loss. Aflibercept is a standard drug for DME treatment. Sometimes, laser treatment is also used along with aflibercept. This study explored whether adding laser therapy to aflibercept provides extra benefit in DME treatment. Systematic review of literature and meta-analysis showed that patients who received both aflibercept and laser therapy had slightly better vision and a small reduction in retinal swelling compared with those who received aflibercept alone. Moreover, patients receiving the combination treatment also required slightly fewer injections. In summary, adding laser therapy to aflibercept does not appear to provide clear additional benefit in improving vision or reducing retinal swelling. There may be a small reduction in the number of injections needed, but more research is required to confirm this finding.",

While the most common inherited retinal diseases (IRDs) involve defects in rod and/or cone function, another group (referred to as congenital stationary night blindness (CSNB)) results from defects in glutamate release from photoreceptors, or conversion of the glutamatergic signal in bipolar cells. One example results from mutations in the CACNA2D4 gene, which encodes a subunit of the voltage-gated calcium channel that is critical for glutamate release from both rod and cone photoreceptors. Mutations in CACNA2D4 result in a range of phenotypes in human patients, from incomplete CSNB to rod-cone dystrophy. In the CACNA2D4 knockout mouse ( \u03b12\u03b44 -/- ), there is slow photoreceptor degeneration, the photoreceptor-to-bipolar cell synapse is disorganized, and the retina lacks scotopic and photopic full-field electroretinogram b-waves; this also results in low visual acuity. Using adult \u03b12\u03b44 -/- mice, we show that recombinant adeno-associated virus (rAAV)-mediated gene therapy directed to rod photoreceptors prevents rod degeneration, restores synaptic organization, retinal function, and improves visual acuity under both light- and dark-adapted conditions. This rescue was maintained for up to 14 months post-treatment. Together, our results demonstrate that synaptic structure and function can be restored in the mature mouse retina in a model of complete synaptic disorganization. The results highlight the neuroprotective potential of targeting synaptic organizing proteins in retinal gene therapy.",

Dysregulated PKA signaling is implicated in diseases including neurodegeneration and cancer. PKA catalytic activity is regulated by two nonredundant regulatory subunits, Type I (RI\u03b1/RI\u03b2) and Type II (RII\u03b1/RII\u03b2), whose divergent functions are not fully understood. We generated double-knockout (KO) cell lines of RI\u03b1/RI\u03b2 and RII\u03b1/RII\u03b2 subunits and performed multiplexed MS-based proteomic and phosphoproteomic profiling under basal and glucose-perturbed conditions. We found that RI and RII loss drives distinct, and often opposite, remodeling of the cellular proteome and phosphoproteome. While both mutants blunted metabolic flexibility to glycolytic stressors and stimuli, RI and RII KO cells exhibited elevated and depressed glycolytic signaling, respectively. Interestingly, RI KO increased the abundance and kinase activity of the PKA catalytic subunit C\u03b1 isoform, leading to an increase in PKA substrate phosphorylation, whereas RII KO decreased the abundance, kinase activity, and substrate phosphorylation by the catalytic subunit C\u03b2 isoform. Notably, one of the most differentially affected PKA sites between RI and RII KOs maps to Tau, whose hyperphosphorylation is a hallmark of Alzheimer's disease. Loss of RI increased Tau phosphorylation, which was not only caused by increased PKA catalytic activity, but also a higher binding affinity of Tau to RII subunits on the negatively-charged flexible linker region. Overall, the present study demonstrates that PKA RI and RII subunits play nonredundant roles in modulating PKA activity, metabolic flexibility, and phospho-regulation of key disease-associated substrates such as Tau.",

Injury to the ON often triggers RGC death and subsequent loss of visual function. Despite its increasing prevalence worldwide, effective therapies for glaucoma remain elusive. Notably, the thirteen-lined ground squirrel (TLGS) exhibits intrinsic neuroprotection during hibernation; however, reproducing this protective state pharmacologically has proven challenging. To elucidate the metabolic mechanisms underlying this resilience, we conducted untargeted metabolomic analyses on TLGS retinas at 6 hours, 3 days, and 7 days following ON crush. Retinas from awake and hibernating animals were compared to identify temporal and state-dependent metabolic signatures. Distinct metabolomic profiles were observed in hibernating animals relative to their awake counterparts. Pathway analyses revealed coordinated regulation of amino acid, lipid, and purine metabolism that likely contributes to hibernation-induced resilience. Furthermore, our findings indicate that hibernating TLGS retinas increase exosome biogenesis, prompting in vitro validation using TLGS-derived exosomes, which demonstrated robust neuroprotective and anti-inflammatory effects. Proteomic and transcriptomic characterization of exosomal cargo identified conserved miRNAs, mRNAs, and proteins implicated in redox balance, cytoskeletal stabilization, and stress-response regulation. Collectively, these data support the hypothesis that metabolic reprogramming and exosome-mediated intercellular signaling underlie hibernation-associated neuroprotection. Modulating these pathways may provide a blueprint for novel therapeutic strategies to mitigate neurodegeneration and promote recovery following optic nerve injury.",

AD is characterized by progressive cognitive decline linked to neuroinflammation and neurodegeneration. Non-steroidal anti-inflammatory drugs (NSAIDs) have been explored as potential neuroprotective agents, particularly diclofenac, which has been proposed to modulate microglial inflammasome signaling. However, prior studies investigating NSAIDs in AD have yielded inconsistent findings. We therefore reexamined the relationship between selected NSAIDs and dementia outcomes in a large longitudinal cohort from the National Alzheimer's Coordinating Center (NACC). We analyzed cross-sectional and longitudinal data from the NACC database collected between 2005 and 2022. Associations between NSAID exposure and dementia, AD, and cognitive trajectories were examined. Propensity score matching was performed to compare NSAID users with matched non-users while adjusting for demographic and clinical confounders. Longitudinal mixed-effects models were used to assess cognitive decline based on Montreal Cognitive Assessment (MoCA) scores. Among 47,165 participants, diclofenac and naproxen use were associated with a lower prevalence of dementia and AD compared with matched non-users, whereas etodolac showed no significant associations. Diclofenac users demonstrated reduced odds of dementia and AD. Naproxen showed similar cross-sectional associations. In longitudinal modeling, diclofenac users had a significantly slower rate of cognitive decline than non-users. These findings suggest a compound-specific association between NSAID use and AD, with diclofenac potentially modulating disease progression through anti-inflammatory mechanisms. The observed modulation of longitudinal cognitive decline supports further investigation of inflammatory pathways, including microglial and inflammasome signaling, as therapeutic targets in biomarker-defined AD populations.",

Yes-associated protein (YAP), a Hippo pathway effector, is known to reprogram stress responses, yet its role in regulating oxidative stress during RGC degeneration is unclear. This study investigated the role of YAP in RGC injury using an in vivo optic nerve crush (ONC) model and an in vitro oxidative-stress model with primary RGCs. YAP expression was modulated pharmacologically and genetically. We assessed its effects on nuclear factor erythroid 2-related factor 2 (Nrf2) signaling-related outcomes; on oxidative stress markers, including superoxide dismutase-1/2 (SOD-1/2), NAD(P)H:quinone oxidoreductase 1 (Nqo-1), and reactive oxygen species (ROS); and on neuroinflammation (microglial and astrocytic activation) via quantitative reverse-transcription PCR and immunofluorescence. YAP activation demonstrated robust neuroprotection in both the in vivo ONC model and in vitro oxidative-stress paradigms, significantly enhancing RGC survival, whereas YAP suppression exacerbated RGC degeneration. Mechanistically, YAP activation was associated with elevated Nrf2 signaling activity, as indicated by upregulation of antioxidant effectors (Nqo-1, SOD-2) and reduced intracellular ROS. YAP activation attenuated neuroinflammation, characterized by decreased microglial reactivity and astrocytic activation, whereas inhibition of YAP reversed these effects. This study identified YAP as a neuroprotective regulator in both in vivo ONC and primary RGC models. YAP activation attenuated oxidative stress and neuroinflammation, which correlated with the activity of Nrf2-mediated antioxidant pathways, highlighting the potential relevance of YAP and Nrf2 interaction for therapeutic targeting in RGC injury.",

This study investigated whether oral lysozyme confers neuroprotection after TBI through gut microbiota-dependent metabolic reprogramming of tryptophan metabolism. In a severe TBI mouse model, neurological function, neuroinflammation, intestinal barrier integrity, and systemic immune homeostasis were assessed following oral lysozyme administration. Fecal untargeted metabolomics, antibiotic-mediated microbiota depletion, and fecal microbiota transplantation (FMT) were used to explore microbiota involvement. Cerebrospinal fluid (CSF) from 10 matched pairs of patients with severe TBI was analyzed for tryptophan pathway metabolites by liquid chromatography-mass spectrometry. Lysozyme improved neurological outcomes, attenuated neuronal apoptosis and neuroinflammation, and restored peripheral CD4+/CD8+ T cell homeostasis. Metabolomics revealed enrichment of fecal tryptophan metabolites (indole-3-carboxaldehyde, indolelactic acid, kynurenic acid [KYNA]) and a shift in cerebral kynurenine metabolism toward the KYNA branch. These associations were abolished by microbiota depletion and reproduced by FMT. Favorable clinical outcomes were associated with higher CSF KYNA and an elevated KYNA/QA ratio. Oral lysozyme was associated with attenuated TBI-induced neuroinflammation and brain injury, potentially through gut microbiota-dependent tryptophan metabolism reprogramming. Concordance between preclinical and clinical metabolomic data supports lysozyme as a candidate microbiota-targeted therapeutic strategy. The KYNA/QA ratio warrants further validation as a prognostic indicator in larger, longitudinal cohorts.",

This cross-sectional observational study included forty-eight diabetic subjects without diabetic retinopathy (NDR group), thirty-nine diabetic subjects with mild or moderate non proliferative diabetic retinopathy (DR group), and forty age- and sex-matched healthy adults (control group). Pupil size and pupillary light reflex were measured monocularly using a PLR-3000 dynamic pupillometer, and OCT/OCTA scans were acquired with a Van Gogh SS-OCTA device in all three groups. Both static and dynamic pupillary parameters differed significantly among the three groups (p <0.001). Pairwise comparisons showed that both basal and smallest pupil diameter were smaller in diabetes with or without retinopathy, compared to healthy control. Notably, pupillary dynamics didn't significantly reduce until retinopathy was present. Pupillary parameters showed a positive correlation with the thickness of the ganglion cell layer and inner plexiform layer in the parafovea, and the vessel density of the superficial vascular plexus and intermediate capillary plexus. Static pupillary abnormalities appear before clinical diabetic retinopathy. Both static and dynamic pupillary abnormalities worsen alongside retinal microvascular and neurodegenerative damages in the early stages of diabetes. Evaluation for autonomic nervous dysfunction is recommended for all patients with diabetic retinopathy.",

We examined the cellular basis for synaptic vulnerability in the auditory system, where three subtypes of spiral ganglion neurons (SGNs)-Ia, Ib, and Ic-carry acoustic information from the cochlea to the brain. In response to noise and aging, a subset of synapses between inner hair cells and SGNs are lost, but it is unclear how this loss varies across SGN subtypes. Using genetic labeling, we showed that Ia SGNs have larger post-synaptic densities (PSDs) than Ib and Ic SGNs and are the most resilient subtype. Ia PSD volumes increase with age and are unchanged after noise exposure. By contrast, average Ib/Ic PSD volumes do not change with age but decrease with noise. Genetic reprogramming of Ib/Ic neurons to a Ia-like identity provides significant protection against noise-induced synaptopathy, linking identity to resilience and providing an entry point for therapeutics.",

While glucagon-like peptide-1 receptor agonists (GLP-1 RAs) show neuroprotective promise in preclinical models, clinical trials have produced conflicting results. This meta-analysis systematically evaluates the efficacy and safety of GLP-1 RAs in PD, specifically distinguishing between symptomatic relief and potential disease modification. We searched PubMed, Scopus, Web of Science, Cochrane Library, and Embase through November 2025 for randomized, double-blind, placebo-controlled trials of GLP-1 RAs in idiopathic PD. The primary motor outcome, the Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III (motor examination), was analyzed using a random-effects model and strictly stratified by \"ON\" versus \"OFF\" medication states. We included four high-quality trials comprising 667 patients. GLP-1 RAs failed to significantly improve motor function in either the OFF-medication state (mean difference [MD]\u2009-\u20090.69; 95% confidence interval [CI]\u2009-\u20092.81 to 1.43; p\u2009=\u20090.52) or ON-medication state (MD\u2009-\u20090.86; 95% CI\u2009-\u20093.35 to 1.63; p\u2009=\u20090.50). Furthermore, no meaningful benefits emerged for non-motor symptoms, cognition, or quality of life. Conversely, treatment significantly increased gastrointestinal adverse events, including nausea (risk ratio [RR]\u2009=\u20092.48), vomiting (RR\u2009=\u20094.53), and clinically concerning weight loss (RR\u2009=\u20093.32). Synthesizing the latest phase 3 data, current GLP-1 RAs offer neither disease-modifying nor symptomatic motor benefits for the broader PD population. Given the pronounced risk of weight loss, their routine use is unwarranted. Future trials must shift focus toward biologically enriched subgroups or newer-generation incretin analogs.",

This pathogenesis is characterized by amyloid-\u03b2 (A\u03b2) aggregation, tau hyperphosphorylation, persistent neuroinflammation, oxidative stress, and synaptic dysfunction. Conventional single-target interventions have consistently failed against this complex interplay of molecular events, thereby highlighting the need for multitarget, systems pharmacology approaches capable of simultaneously modulating convergent pathways. Apremilast (APR), an FDA-approved, orally bioavailable phosphodiesterase-4 (PDE4) inhibitor, has recently emerged as a favorable drug repurposing candidate capable of elevating intracellular cAMP and triggering a cascade of neuroprotective mechanisms. Preclinical investigations from A\u03b2-challenged neuronal cultures to high-fat diet/streptozotocin-induced rodent models of AD demonstrate that APR attenuates A\u03b2-induced cytotoxicity, improves cognitive performance, and preserves neuronal and synaptic integrity. Mechanistically, APR mitigates NF-\u03baB-mediated neuroinflammation through I\u03baB\u03b1 stabilization, thereby reducing the release of proinflammatory cytokines such as TNF-\u03b1 and IL-6; activates the Nrf2/HO-1 antioxidant defense pathway, and, via cAMP-dependent PI3K/Akt signaling, inhibits GSK-3\u03b2 to prevent tau hyperphosphorylation, synaptic loss, and neuronal degeneration. This review synthesizes current mechanistic evidence supporting apremilast as a potential multitarget repurposing candidate in AD, thereby addressing key knowledge gaps in the current literature. All supporting evidence was compiled from peer-reviewed sources indexed in PubMed, Web of Science, and Scopus. Guided by network pharmacology and systems biology frameworks, APR's polypharmacological profile positions it as a compelling multitarget candidate for advanced in vivo validation, human iPSC-derived neuronal studies, and AI-driven therapeutic discovery pipelines.",

While amyloid-\u03b2 and tau pathologies have long dominated disease models, growing evidence highlights neuroinflammation as a critical driver of early pathological changes. In particular, microglia-mediated inflammatory signaling has emerged as a key regulator of synaptic integrity. This review focuses on the interleukin-1\u03b2 (IL-1\u03b2)-NLRP3 inflammasome axis as a central mechanism linking innate immune activation to aberrant synaptic pruning in early Alzheimer's disease. Activation of the NLRP3 inflammasome in microglia by amyloid-\u03b2 and related danger signals leads to caspase-1-dependent maturation and release of IL-1\u03b2. Elevated IL-1\u03b2 amplifies inflammatory signaling, alters microglial phenotype, and promotes complement-mediated tagging of synapses, resulting in excessive elimination of functional synaptic connections. Experimental evidence from in vitro systems, transgenic mouse models, and pharmacological inhibition studies supports a causal role for this axis in synapse loss, impaired synaptic plasticity, and cognitive deficits. Importantly, these inflammatory and synaptic alterations occur at early disease stages, underscoring their relevance to disease initiation rather than late-stage neurodegeneration. The review further discusses the impact of IL-1\u03b2-NLRP3 signaling on neuronal network function, hippocampal plasticity, and cognitive performance, as well as its translational implications. Therapeutic strategies targeting inflammasome activation or IL-1\u03b2 signaling show promise in preserving synaptic function in preclinical models. Overall, the IL-1\u03b2-NLRP3-synapse axis represents a compelling framework for understanding early Alzheimer's disease pathology and offers a rational target for early intervention strategies to slow disease progression.",

This prospective cross-sectional study included 38 healthy participants who underwent peripapillary RNFL imaging using 5 OCT devices: Heidelberg Spectralis, TowardPi BMIZAR 400\u2009kHz swept-source OCT, Huvitz HOCT-1/1F, NIDEK RS-1 Glauvas, and Topcon Maestro 2. RNFL thickness was analyzed in the superior, nasal, inferior, and temporal sectors, as well as global mean thickness. Three consecutive measurements were obtained for each eye with each device to assess intra-device repeatability. Repeatability was evaluated using repeated-measures analysis of variance. Inter-device reliability was assessed using intraclass correlation coefficients, with Heidelberg Spectralis as the reference. Agreement between devices was further evaluated using Bland-Altman analysis. Excellent intra-device repeatability was documented across all platforms. However, marked inter-device variability demonstrated sector-dependent patterns: global RNFL measurements showed moderate agreement (intraclass correlation coefficient: 0.346-0.805), while nasal and temporal sectors exhibited disproportionately higher variability (absolute percentage error up to 20.76% in the nasal sector; limits of agreement width ranging from 20.23% to 35.52% in temporal). Bland-Altman analyses revealed device-specific bias signatures (Huvitz HOCT-1/1F: -8.17% global bias; NIDEK RS-1 Glauvas: +10.59%; Topcon Maestro 2: -4.47%), indicating systematic, reproducible platform-inherent differences rather than random measurement noise. While intra-device repeatability is excellent, inter-device RNFL measurements remain substantially discordant, particularly in nasal and temporal sectors, where absolute percentage error reaches up to 20.76% and limits of agreement exceed 35%, a phenomenon termed sector-dependent device discordance. Global RNFL measurements may appear concordant while sectoral measurements diverge, creating a theoretically plausible risk for false progression detection, pending validation in glaucomatous eyes. RNFL measurements are not interchangeable across platforms and are particularly unreliable for sector-specific assessment. Device-consistent monitoring is essential for glaucoma follow-up; multicenter studies and device switching scenarios warrant platform-specific normalization strategies.",

A 42-year-old man presented with blurred vision and pain in his right eye. He used disposable soft contact lenses for 2 weeks with appropriate care. He had open-angle glaucoma, atopic dermatitis, and diabetes mellitus. At the initial presentation, a corneal epithelial defect, cell infiltration, strong hyperemia, hypopyon, and inflammation in the anterior chamber were observed. Anterior segment optical coherence tomography disclosed corneal edema and cloudiness, and the central corneal thickness had increased to 988\u2009\u03bcm. The best-corrected visual acuity was counting fingers at 10\u2009cm. The patient did not respond to the initial treatment with ofloxacin and steroids. The culture of the scraped sample from the contact lens case grew M. chelonae, and topical tobramycin was administered, which was effective based on antimicrobial susceptibility. It took 4 months to treat the keratitis, and the best-corrected visual acuity improved to 0.5, although anterior and posterior corneal irregularities remained. Nontuberculous M. chelonae should be considered in patients with treatment-resistant keratitis, especially in contact lens users. Topographic changes are important for evaluating corneal edema and irregular astigmatism, which impair visual function after keratitis.",

Plant-derived bioactive metabolites (e.g., quercetin, puerarin) have been reported to modulate multiple DR-relevant pathways in preclinical studies against DR pathogenesis, including modulation of angiogenesis, oxidative stress, and inflammation. However, their clinical translation is hindered by compound- and route-dependent pharmacokinetic challenges, including poor solubility, extensive metabolism, rapid ocular clearance, and restricted posterior-segment exposure. This review explores nanomaterial-enabled delivery systems to overcome these barriers, detailing platforms such as polymeric nanoparticles, lipid-based carriers, and exosomes engineered to enhance solubility, penetration, and sustained release. Key strategies including barrier-specific size optimization, surface engineering, and ligand functionalization are critically analyzed. Integrated preclinical frameworks utilizing in vitro models and in vivo rodent studies, along with pharmacokinetic and safety evaluations, are emphasized. Finally, regulatory considerations and clinical trial challenges are addressed.

Building on our previous findings that BPS induces anxiety-like behaviour and oxidative damage in zebrafish, the present study investigates the mechanistic basis of BPS-mediated neurotoxicity with a focus on stress-activated kinase signalling, antioxidant defences, and neurotrophic regulation. Adult zebrafish were exposed to a sub-lethal concentration of BPS (63.93 \u00b5M) for 7, 14, and 21 days, followed by neurobehavioral, biochemical, molecular, and histological analyses. Chronic BPS exposure resulted in pronounced anxiety-like behaviour and deficits in recognition memory, as evidenced by performance impairments in the novel tank diving test and novel object recognition test. These behavioural alterations coincided with elevated oxidative stress, including increased lipid peroxidation and protein carbonylation, alongside a progressive decline in superoxide dismutase activity. BPS also caused a significant, time-dependent rise in intracellular calcium levels, suggesting disrupted cellular homeostasis. Neuromorphological assessment revealed marked neuronal loss and pyknosis in the periventricular grey zone of the optic tectum, consistent with oxidative and excitotoxic damage. At the molecular level, western blot analysis showed robust activation of the c-Jun N-terminal kinase (JNK) pathway, evidenced by elevated phosphorylated c-Jun, accompanied by a substantial reduction in Nrf2 expression, indicating suppressed antioxidant defence capacity. In parallel, expression of brain-derived neurotrophic factor (BDNF) was significantly decreased following prolonged exposure, pointing to impaired neurotrophic support and synaptic plasticity. Together, these findings demonstrate that BPS induces neurobehavioral disturbances through a multifaceted mechanism involving oxidative stress, calcium dysregulation, activation of pro-apoptotic JNK signalling, suppression of Nrf2-mediated antioxidant activity, and inhibition of BDNF expression.",

Nevertheless, the regulatory mechanism by which Mel modulates mGluR1/glutamate signaling in retinal ischemia-reperfusion (I/R) injury and its downstream effects on ferroptosis and oxidative stress remain poorly understood. Here, bulk RNA sequencing identified that the Mel receptors Mt1/Mt2 and ferroptosis/iron-redox regulators (Gpx4, Fth1, and xCT) were significantly downregulated after retinal I/R. Mel improved retinal structural and visual function, visual-guidance behavior, and electrophysiological responses following I/R while concurrently reducing ferroptotic and inflammatory injury markers. These benefits were largely abolished by Mel membrane receptor antagonists. Mechanistically, Mel upregulated Homer1a in vivo and in vitro in a receptor-dependent manner. Conditional deletion of Homer1a in transgenic mice, as well as Homer1a knockdown in retinal ganglion cells (RGCs), abolished the protective effects of Mel on visual function, along with its anti-ferroptotic and anti-inflammatory activities. Molecular docking and immunoprecipitation assays demonstrated that Mel restored the interaction between Homer1a and mGluR1 and activated the xCT/GSH/Gpx4 antioxidant axis. Pharmacologic inhibition of xCT with the buthionine sulfoximine (BSO) simulation pr genetic interference with xCT expression counteracted the protective effects of Mel. Mel also enhanced Nrf2-mediated transcriptional expression of cCT in a Homer1a/mGluR1-dependent manner. Collectively, our results define a Mel-Homer1a/mGluR1-Nrf2/xCT signaling cascade that promotes RGCs survival after I/R by suppressing ferroptosis/iron-redox reactions, thereby providing a potential translatable strategy for receptor-targeted intervention in I/R-related retinal damage.",

Herein, we develop an engineered exosomal siRNA delivery platform for systemic, neuron-targeted RNA transport to the brain. The platform leverages exosomes derived from an immortalized mouse hippocampal neuronal cell line as a biomimetic and functionally privileged material source, enhancing neuronal uptake and intracellular delivery efficiency. Through surface functionalization with a rabies virus glycoprotein-derived peptide, the system enables receptor-mediated BBB transcytosis and programmable siRNA loading. In human cortical organoids, the platform achieves efficient cytosolic delivery and robust gene silencing in neurons, demonstrating high delivery precision and bioavailability. As a proof of concept, targeting receptor-interacting protein kinase 3 (RIPK3) modulates necroptosis, a key pathway in inflammatory neurodegeneration. In transgenic mouse models, systemic administration suppresses RIPK3/MLKL signaling, reduces neuronal loss, and alleviates neuroinflammation and tau-associated pathology. Transcriptomic analyses further indicate stabilization of neuronal homeostasis across vulnerable brain regions. Collectively, the study establishes a modular and programmable exosomal RNA delivery platform and highlights age-defined, cell-derived biomaterials as a generalizable strategy for overcoming delivery barriers in neurological diseases.",

Licochalcone A (LCA), has demonstrated antidiabetic and anti-inflammatory effects. This study aimed to evaluate its neuroprotective effects under metabolic syndrome conditions. For this purpose, male C57BL/6J mice were fed either with control (CT) or high-fat diet (HFD) from weaning. At eight months, animals received intraperitoneal LCA (15\u202fmg/kg/day) or saline three times per week for four weeks. The resulting groups were CT Saline, HFD Saline, and HFD LCA. Cognitive and metabolic alterations were assessed through behavioral tests and glucose/insulin tolerance assays. Peripheral and/or central markers of metabolism, amyloid burden, inflammation, and synapsis were analyzed using histological staining, immunohistochemistry, Golgi staining, Western blot, ELISA, and RT-PCR. The results demonstrated that LCA administration improved metabolic outcomes by reducing body and liver weight, enhancing glucose tolerance, and improving liver histology. These effects were associated with modulation of insulin signaling pathways, including PTP1B inhibition and AKT activation in the liver and the hippocampus. LCA also reduced HFD-induced A\u03b2 accumulation, which was accompanied by increased LRP1 expression, and attenuated the expression of inflammatory related markers, such as TLR4 and glial activation. Moreover, these improvements were associated with increased levels of synaptic proteins (BDNF, PSD95, DBN1), and synaptic plasticity markers (P-CREB and P-LIMK1), along with preservation of dendritic spine density and improved memory performance. In conclusion, these findings support LCA as a promising candidate for treating HFD-induced neurodegenerative conditions, acting through modulation of metabolic and inflammatory pathways across the liver-brain axis.",

Outcomes included incident DR, progression from mild/moderate nonproliferative DR to severe nonproliferative DR, proliferative DR, or interventions required in advanced DR, and incident DR complications. Hazard ratio (HR) and 95% confidence intervals (CI); significance threshold <0.9 or >1.1. After successful PSM, there were 110,495 (6-months), 99,187 (1-year), 63,194 (3-years), and 40,810 (5-years) DR-naive study patients with the respective GABAergic prescription durations of interest. Compared to 109,603 DR-naive control patients, study patients demonstrated a significantly reduced HR for DR development at all time points from 6-months (HR 0.61, 95% CI 0.57-0.65) to 5-years (HR 0.81, 95% CI 0.77-0.85). Study patients (n=14,644) with baseline mild/moderate nonproliferative DR had a significantly reduced hazard of progressing to severe nonproliferative DR, proliferative DR, or DR interventions with 6-months (HR 0.75, 95% CI 0.68-0.82) and 1-year (HR 0.69, 95% CI 0.73, 0.86) GABAergic exposure. Prescription for 6-months (HR 0.74, 95% CI 0.68-0.80) to 3-years (HR 0.80, 95% CI 0.84-0.86) was associated with a significantly reduced hazard for DR complications. Stratification by 4 specific medication indications consistently showed a reduced hazard for DR development with a 6-month prescription duration. GABAergic medication use, particularly short-term exposure, is associated with a reduced hazard of DR development, progression, and complications. These exploratory findings support a potential role of GABAergic modulation in diabetic retinal disease.",

This review provides a comprehensive synthesis of the structural, functional, and pharmacological landscapes of the CDK family, emphasizing their evolutionary diversification and expanding therapeutic relevance. We explored the conserved architecture of CDK catalytic cores and delineated isoform-specific regulatory adaptations that have evolved through gene duplication and sequence divergence. These evolutionary modifications have enabled the functional repurposing of CDKs across eukaryotic species, which play critical roles in immune modulation, metabolic control, and synaptic plasticity. We also analyzed activation mechanisms, cyclin-binding interfaces, and substrate-recognition features that govern CDK activity. We then examine the pathological consequences of CDK dysregulation in oncogenesis, neurodegeneration, and autoimmune disorders with a focus on drug resistance in current clinical approaches. We further highlighted emerging therapeutic strategies, including transcription-targeting CDK inhibitors, proteolysis-targeting chimeras (PROTACs), covalent inhibitors, and artificial intelligence-guided drug discovery platforms that promise to overcome these challenges. Special attention is given to understudied and emerging CDKs, notably CDK11 (cancer), CDK14 (development), and CDKL5 (neurodegeneration), which represent untapped therapeutic frontiers with disease-specific relevance. Collectively, this review repositions CDKs as cell cycle regulators and central signaling integrators within complex disease networks. We propose a structural and mechanistic framework to guide the rational targeting of CDKs in the precision medicine era, paving the way for the next generation of kinase-based therapeutics.",

Chronic disruption of intracellular Ca\u00b2\u207a homoeostasis is a convergent feature of neurodegenerative disorders, particularly Alzheimer's disease (AD) and Parkinson's disease (PD). In these conditions, sustained or repetitive Ca\u00b2\u207a elevations promote prolonged activation of the CaN/NFAT pathway, thereby linking Ca\u00b2\u207a dysregulation to persistent cellular responses. In this review, we summarise the molecular organisation and regulation of the Ca\u00b2\u207a/CaN/NFAT pathway and discuss its physiological roles in neurons and glial cells, including synaptic plasticity, neurodevelopment, neurogenesis, and neuroinflammatory responses. We critically examine experimental evidence linking CaN/NFAT signalling to AD and PD, distinguishing direct mechanistic roles from associative and model-dependent findings. Across disease contexts, the CaN/NFAT axis appears to function as a molecular node at which diverse insults, including amyloid-\u03b2 and tau aggregates, \u03b1-synuclein toxicity, mitochondrial dysfunction, and chronic inflammatory cues, converge under conditions of sustained Ca\u00b2\u207a dysregulation. We propose that the pathological relevance of CaN/NFAT lies less in pathway activation per se than in its capacity to convert chronic Ca\u00b2\u207a-dependent stress signals into persistent transcriptional states affecting synaptic integrity, inflammatory tone, and cellular resilience. We conclude by discussing current therapeutic strategies targeting this pathway, their limitations, and the need for temporally and cell-type-specific modulation.",

This study aimed to evaluate the protective effects of Pycnogenol in a rat model of thioacetamide-induced hepatic encephalopathy. Thirty-two rats were assigned to four groups: control, HE (TAA), and two treatment groups receiving Pycnogenol at 5\u00a0mg/kg and 10\u00a0mg/kg. HE was induced by intraperitoneal administration of TAA at 200\u00a0mg/kg for three consecutive days. Pycnogenol was administered orally for 14 days prior to and during TAA exposure. Behavioral tests (locomotor activity, elevated plus maze), histopathological evaluations, biochemical parameters, immunohistochemical staining, and gene expression analyses (qPCR) were performed. Pycnogenol administration resulted in significant improvements in locomotor activity, reductions in oxidative stress markers, and decreased expression of IL-1\u03b2, TNF-\u03b1, NF-\u03baB, and caspase-3. Histopathological examination revealed alleviation of hepatic and neuronal degeneration. Immunohistochemistry confirmed reduced GFAP and iNOS staining in brain tissues. Pycnogenol demonstrated neuroprotective and hepatoprotective effects in this experimental model, likely through modulation of oxidative stress and inflammatory pathways. Although these findings highlight the potential translational relevance of Pycnogenol as a supportive strategy for hepatic encephalopathy, further studies in chronic models and clinical settings are required to confirm its therapeutic applicability.",

Although dexmedetomidine, an \u03b12 receptor agonist, exhibits neuroprotective effects, it remains unknown whether it improves post-resection cognitive function by modulating the mTOR pathway. To discuss the influence of dexmedetomidine on the mTOR signaling pathway in the hippocampus of POCD rats after partial hepatectomy. Thirty Wistar rats were randomly divided into three equal groups: normal, model and treatment. The treatment group received dexmedetomidine, whereas the other two groups received saline. Histopathology, cognitive function and related gene/protein expression were compared among groups received saline. The treatment group showed improved hippocampal neuronal structure and arrangement compared to the model group, though still below normal levels; neural apoptosis was significantly reduced (P<0.05), and spatial learning and memory were enhanced; Akt expression was partially restored, while mTOR, NF-\u03baB and TNF-\u03b1 expression (protein/mRNA) remained higher than normal but significantly lower than in the model group (P<0.05). Dexmedetomidine ameliorates postoperative cognitive dysfunction in rats after liver resection by inhibiting the hippocampal mTOR pathway, reducing neuronal damage and inflammation.",

Loss-of-function mutations abolish intraretinal capillary formation in mice. In humans, mutations in NDP, which encodes norrin, cause Norrie disease, characterized by retinal hypovascularization and congenital blindness, and X-linked familial exudative vitreoretinopathy (FEVR), resembling retinopathy of prematurity (ROP). We evaluated adeno-associated viral (AAV) vectors expressing norrin as gene therapy for Norrie disease, FEVR, and ROP. AAV2-7m8 and AAV-ShH10 were tested in juvenile wild-type and norrin-deficient (Ndp KO) mice via intravitreal injection at postnatal day 7, with some mice subjected to oxygen-induced retinopathy (OIR). AAV2-7m8 transduced M\u00fcller glia, while AAV-ShH10 targeted retinal ganglion cells. Both vectors fully restored intraretinal capillary growth in Ndp KO mice, normalizing vessel density and plexus organization, preserving the blood-retinal barrier, and rescuing visual function. In OIR, scAAV2-7m8-huNorrin reduced vaso-obliteration and neovascular tuft formation, increasing deep plexus coverage, and suppressed Vegfa164 and Ang-2 upregulation. The findings demonstrate that AAV-mediated norrin delivery efficiently targets retinal glia and neurons, restores vascular structure and function, stabilizes the blood-retinal barrier, and mitigates OIR-induced pathological angiogenesis, supporting its potential as a therapeutic strategy for Norrie-related retinopathies and ROP.",

Calcium interactions at the first retinal synapse are necessary for normal retinal development and vision. Calcium binding protein 4 (CaBP4) modulates these interactions, and mutations in CaBP4 or the voltage-gated calcium channel lead to similar forms of visual impairment. We identified a spontaneous mutation in CaBP4 in dogs that results in synaptic loss of function, immaturity of synaptic ribbons, and disorganization and thinning of the outer plexiform layer (OPL). Adeno-associated virus (AAV)-mediated gene augmentation therapy restored synaptic function and vision and led to synaptic ribbon maturation and elongation. Therapy also resulted in retinal layer preservation and re-organization, including expansion of the previously thin adult OPL. We show that the restoration of calcium regulation is, therefore, requisite for retinal plasticity and remodeling. This first naturally occurring large-animal model of mutant CaBP4 recapitulates components of the human disease and illustrates the potency of gene therapy in reversing blindness caused by the loss of CaBP4, paving the way for a cure. Structural and molecular changes following gene therapy demonstrate the phenomenal plasticity of the OPL and its synaptic machinery, highlighting the potential of neuroplasticity in the mammalian central nervous system.",

However, the neuroprotective effect of 3,6-DHF on MPTP-induced oxidative stress and neuroinflammation in a PD mouse model has not yet been investigated. In this study, we investigated whether 3,6-dihydroxyphenylhydrazine (3,6-DHF) is protective against MPTP-induced oxidative stress and neuroinflammation and explored its potential neuroprotective mechanism. 3,6-DHF was administered orally at doses of 5, 10, and 20\u2009mg/kg/day for 7 days. MPTP was administered at 30\u2009mg/kg/day via intraperitoneal injection, once daily, for 4 consecutive days, from day 4 to day 7. In vitro, 3,6-DHF enhanced cell survival and suppressed inflammatory markers and NF-\u03baB/MAPK signaling pathways associated with microglial activation in LPS-stimulated BV-2 cells. In the in vivo study, 3,6-DHF reduced PD motor deficits and enhanced motor performance in the open field test, beam walking, rotarod, pole, and grip strength tests. 3,6-DHF significantly reduced neuronal oxidative stress by decreasing lipid peroxidation, which in turn helped restore impaired antioxidant enzyme activity, while also enhancing the expression of Nrf2 and HO-1 proteins. It also increased the expression levels of the TH protein, reduced the expression of inflammatory mediators, and inhibited the activation of microglia and astrocytes induced by MPTP. These results suggest that 3,6-DHF effectively modulates neuroprotective, antioxidant, and neuroinflammatory processes and improves motor functions, highlighting its potential for further exploration in PD treatment.",

Its treatment is a clinical challenge due to the risk of reperfusion injury and the limited efficacy of thrombolytic therapies; therefore, novel therapeutic approaches are needed. Histone deacetylase inhibitors (HDACi) have emerged as neuroprotective agents in stroke models, but their effect on preserving BBB integrity is unexplored. Our aim was to investigate the effects of the HDACi, suberoylanilide hydroxamic acid (SAHA), on BBB changes in a cell culture model of ischaemic stroke. The effects of SAHA were tested on a human BBB co-culture model following a 6-h oxygen-glucose deprivation (OGD) under normoxia and during a 24 h reoxygenation (OGD/R). SAHA treatment ameliorated the OGD/R-induced loss of BBB integrity, as shown by an increase in transendothelial electrical resistance and reduced BBB permeability. The expression of genes involved in cell proliferation decreased, whereas an increase was measured for basement membrane protein, glycocalyx-synthesis enzyme and Wnt signalling-related genes. SAHA treatment elevated the claudin-5 protein expression and a metabolic shift from glycolysis to aerobic respiration was observed. Our results suggest that SAHA could be a potential adjunctive therapeutic drug for the treatment of ischaemia-reperfusion injury via BBB protection. Because SAHA has already been approved for human use as the anticancer drug vorinostat, its repurposing to restore BBB functions and prevent poststroke damages may be greatly facilitated.",

In this study, we evaluated A\u03b2 aggregation inhibitory activity of synthesized naphthoquinone derivatives as well as improvement in cognitive functions and metabolite profiling of brain tissues using scopolamine (SCO)-induced mice. Compound 888 (2-(4-(2,3,4-trimethoxybenzyl)piperazin-1-yl)naphthalene-1,4-dione, [TPN]) showed the highest A\u03b2 aggregation inhibitory activity (IC50\u2009=\u20090.14\u2009\u03bcM), and was more potent than the reference compound curcumin (IC50\u2009=\u20091.63\u2009\u03bcM). Compound TPN showed effective monoamine oxidase (MAO)-A, MAO-B, acetylcholinesterase, and butyrylcholinesterase inhibitions at 10\u2009\u03bcM, likely as candidates for multitarget-directed ligands. TPN was permeable through the blood-brain barrier, and non-toxic to MDCK and SH-SY5Y cells. TPN displayed prolonged and stable interactions with A\u03b242 during molecular dynamics simulations, in contrast to the short-lived contacts observed for curcumin. Cognitive impairment was significantly improved by TPN-treatment in behavioral tests. TPN treatment attenuated A\u03b2-related protein expression, inflammatory responses, oxidative stress-related changes, and apoptosis-related alterations, while preserving hippocampal pyramidal neurons and their typical morphology. In metabolite profiling, TPN modulated a narrower set of pathways mainly related to amino acid and kynurenine metabolism, whereas donepezil induced broader adjustments involving amino acid, mitochondrial/energy, and lipid-related pathways compared to those in the serum and cortex of the SCO group, in contrast to those in the hippocampus. Collectively, a potent A\u03b2 aggregation inhibitor TPN showed significant cognitive improvement, accompanying by neuroprotective effects, decreasing inflammation, and retaining neuron structures, exhibiting changed metabolic profiles compared to the control treatments. These findings suggest that TPN has cognitive-protective and neuroprotective potential under scopolamine-induced impairment conditions and warrants further validation in AD-relevant models.",

Nicotine disrupts neuronal firing in the brain's reward system, an effect regulated by estrogen. In this study, we hypothesized that exposing human female neurons to both nicotine and estrogen would activate distinct signaling pathways. We treated human female SH-SY5Y neurons with nicotine and estrogen, and compared these to treatments with each substance alone or vehicle control. Using PamGene PamStation technology, we created an atlas of over 500 kinase activities per sample. We found that nicotine modulates MAP kinase pathways in a dichotomous manner. Estrogen showed unique kinase effects, and in combination with nicotine, elicited diverse pathway responses-some kinases becoming hyperactive and others hypoactive. Bioinformatics analysis highlighted several kinases as central to this combined signaling, including PKC\u0269 and TAO, which showed higher kinase activity only with combined treatment and have known links to behavior in rodent models. Conversely, kinases such as the insulin receptor (INSR), HER2, FAK1, and ABL1 exhibited decreased activity under combined treatment. These findings reveal nicotine-specific kinase mechanisms and suggest potential targets for pharmacotherapy aimed particularly at females with high estrogen levels and nicotine use disorder.",

From the UK Biobank, we identified glaucoma cases (n = 1465) and 10-fold age- and sex-matched controls (n = 14,650). Magnetic resonance imaging modalities comprised T1-weighted structural, diffusion tensor imaging, and neurite orientation dispersion and density imaging. Associations with glaucoma status and ophthalmic measures (RNFL, GCL, and IOP) were assessed using regression models adjusted for age, sex, polygenic risk score, and Townsend Deprivation Index, with false discovery rate correction. Glaucoma was associated with reduced gray matter volume in primary visual regions (lateral geniculate nucleus, optic chiasm, intracalcarine cortex, and occipital pole) and diffusion tensor imaging/neurite orientation dispersion and density imaging abnormalities in the posterior thalamic radiation (all P < 0.001). Glaucoma was also associated with secondary regions (lateral occipital cortex, lingual gyrus, and occipital fusiform gyrus) and microstructural changes in the inferior fronto-occipital and inferior longitudinal fasciculus (all P < 0.001). Higher-order and supporting regions were also associated with glaucoma, including the right putamen and paracingulate gyrus (P < 0.05). The RNFL (P < 0.05) and GCL (P < 0.01) correlated linearly with most primary visual regions, whereas the IOP showed no significant associations. Glaucoma is associated with structural and microstructural brain changes beyond the eye to primary, secondary, and higher-order brain regions. These changes correlate with RNFL and GCL thinning but not IOP. Involvement of the occipital pole is consistent with the plausibility of trans-synaptic degeneration in glaucoma.",

This study investigated the potential neuroprotective effects of a combined treatment consisting of artemisinin, N-acetylcysteine, resveratrol, and hesperidin in a streptozotocin (STZ)-induced intracerebroventricular (ICV) rat model of AD. Twenty 8-week-old rats were divided into four groups: control, SHAM, STZ-ICV, and STZ-ICV receiving oral administration of the compound combination for 30 days. Cognitive performance was evaluated using the Morris water maze and passive avoidance tests. Neurodegenerative and molecular changes were assessed through Western blot analysis of phosphorylated tau, amyloid-\u03b2-related markers, and apoptosis- and inflammation-associated proteins. Histological analyses included Nissl staining and immunofluorescence for amyloid deposition and caspase-3 expression. Results demonstrated that STZ-ICV administration induced significant cognitive impairment, neuronal loss, and increased amyloid-\u03b2 and phosphorylated tau levels. Treatment with the combined compounds partially improved behavioral performance and was associated with reductions in amyloid-\u03b2 deposition, tau phosphorylation, and caspase-3 expression, along with improved neuronal preservation in the hippocampus. These findings suggest that the combined administration of artemisinin, N-acetylcysteine, resveratrol, and hesperidin exerts multi-target neuroprotective effects in an experimental AD model, potentially through modulation of oxidative stress, neuroinflammation, and apoptotic pathways. However, further studies are required to evaluate pharmacokinetics, safety, and translational relevance before clinical application.",

Rather than representing biochemical redundancy, coexistence reflects a conserved organizational strategy that expands neural coding capacity through chemical multiplexing. Dual vesicular architecture-small clear vesicles for rapid synaptic transmission and large dense-core vesicles for activity-dependent peptide release-creates stimulus-intensity-dependent recruitment of distinct signaling layers. Classical transmitters primarily mediate millisecond-scale synaptic precision, whereas peptides engage slower G-protein-coupled receptor pathways that modulate excitability, plasticity, gene expression, and neuron-glia interactions. Across mammalian circuits, cotransmission regulates oscillatory coherence, learning and memory, motivational states, endocrine integration, sensory gain control, and autonomic balance. Peptidergic signaling is transcriptionally regulated and dynamically remodeled during development, stress, injury, and disease. Dysregulation contributes to chronic pain, addiction, stress-related disorders, epilepsy, cardiovascular dysfunction, and neurodegeneration. Therefore, neuropeptide-neurotransmitter coexistence constitutes a core computational principle of the nervous system, enabling temporal stratification and adaptive plasticity without expanding anatomical connectivity. Understanding chemical multiplexing is essential for linking molecular dynamics to circuit stability and vulnerability in health and disease.",

To address this, this study investigates the PARthanatos pathway, a form of regulated cell death triggered by DNA damage. Utilizing MNNG-induced cellular PARthanatos models, we screened a library of 2,939 traditional Chinese medicine monomers and identified Bruceine E, a natural product derived from Brucea javanica (bitterwood), as a potent inhibitor of PARthanatos at nanomolar concentrations, acting via the inhibition of PARP-1 overactivation. Bruceine E effectively prevents the accumulation of PAR-modified proteins, mitigates mitochondrial membrane potential collapse, and inhibits AIF nuclear translocation. Mechanistically, molecular docking, molecular dynamics simulations, surface plasmon resonance (SPR), and thermal stability assays demonstrate that Bruceine E interacts with the NAD + catalytic pocket of PARP-1 through six hydrogen bonds, exhibiting fast-binding and slow-dissociation kinetics. Furthermore, PARP1 overexpression rescue experiments confirmed that PARP1 overexpression markedly reversed the neuroprotective effect of Bruceine E, indicating that its pharmacological action is specifically dependent on PARP1 regulation. In a permanent distal middle cerebral artery occlusion (pdMCAO) model of C57BL/6 mice, a single intraperitoneal injection of 10\u00a0mg/kg Bruceine E administered 4.5\u00a0h after occlusion reduced infarct volume by approximately 80.2%, histological evidence confirmed that a single intraperitoneal administration of BE provided effective neuroprotection against ischemic brain injury.",

Multiple studies have further suggested a key role for herpesviruses, such as cytomegalovirus (CMV). Using transgenic 3xTg-AD mice, we demonstrate that systemic infection with the \u03b2-herpesvirus murine CMV (MCMV) accelerates the development of cognitive decline, tauopathy and synaptic loss in the hippocampus, all of which are key features of AD. Accelerated disease progression after infection was associated with substantial lymphocyte infiltration into the brain, dominated by MCMV-specific effector memory CD8+ T cells expressing CXCR3. T cell receptor analyses revealed that clonally diverse virus-specific CD8+ T cells were selectively recruited into the brain during the development of AD. T cell depletion or treatment with the antiviral drug valganciclovir during chronic infection reduced lymphocytic infiltrates in the brain and reversed cognitive decline. These data provide a mechanistic link between chronic viral infections and the development of AD.",

However, identifying inhibitors that selectively inhibit LIMK1 over LIM domain kinase 2 (LIMK2) has proven to be challenging. A viable strategy to overcome this difficulty is the development of covalent inhibitors, which can offer both potency and selectivity for LIMK1 due to a reactive cysteine, C349, near the active site absent in its paralog LIMK2. Here we identify an irreversible covalent inhibitor of LIMK1 (cLIMK1i), which is highly selective for LIMK1 over both LIMK2 and a panel of over 100 kinases. A crystal structure of LIMK1 soaked with cLIMK1i reveals it is a type I inhibitor occupying the ATP-binding site with its acrylamide moiety oriented toward the P-loop where C349 resides. Computational modeling supports that the P-loop of LIMK1 can adopt a conformation compatible with covalent bond formation. Biochemical and biophysical characterization of the interaction of cLIMK1i with LIMK1 demonstrates that the covalent bond with LIMK1-C349 is essential for its potent inhibition. These results support covalent inhibition of LIMK1 as a viable strategy for selectively inhibiting LIMK1 over LIMK2 and other kinases.",

Reduced slow-wave sleep, increased fragmentation, and circadian instability may facilitate amyloid-\u03b2 accumulation, tau propagation, neuroinflammation, oxidative stress, and impaired glymphatic clearance. Yet the physiological factors that predispose older adults to unstable sleep remain insufficiently integrated into models of brain aging. This Review advances a sleep-muscle-brain framework in which sarcopenia, sarcopenic obesity, and insulin resistance are conceptualized as modifiable muscle-metabolic conditions that may bias sleep continuity and shape the biological impact of sleep disruption. We examine irisin/FNDC5-BDNF signaling as a hypothesis-generating candidate modifier of metabolic regulation, neurotrophic support, and brain resilience, while emphasizing that direct evidence for a causal role in human sleep regulation remains insufficient. Irisin-related pathways intersect with insulin sensitivity, inflammatory control, and BDNF-dependent synaptic plasticity, all of which are relevant to the physiological context in which sleep disruption may influence Alzheimer's disease pathophysiology. We propose that age-related attenuation of muscle endocrine signaling, together with insulin resistance and low-grade inflammation, may lower the threshold at which sleep fragmentation translates into amyloid/tau dyshomeostasis, glial activation, and network dysfunction. Rather than treating sleep disturbance as an isolated brain-centered risk factor, this framework positions sleep as a biobehavioral hub through which peripheral aging processes can modulate neurodegenerative resilience. The Review integrates evidence from sleep neuroscience, geroscience, metabolism, and neurodegeneration, and identifies experimentally testable predictions. A sleep-muscle-brain perspective may help refine risk stratification and guide multimodal interventions combining sleep optimization, resistance exercise, metabolic targeting, and Alzheimer's disease biomarker monitoring.",

Among them, compound 1 is a unique C16-type eudesmane sesquiterpenoid featuring a 6/6/5-membered scaffold, 2-3 are nor-eudesmane sesquiterpenoids and 5 contains a rare 6/6/3/5 tetracyclic skeleton. Their structures including absolute configurations were elucidated by extensive spectroscopic methods, single-crystal X-ray crystallographic and ECD calculation. All compounds were evaluated for their inhibitory effect on nitric oxide (NO) production induced by lipopolysaccharide (LPS) in BV-2 cells and neuroprotective effect induced by H2O2 in PC12 cells. The results showed that four compounds exhibited significant NO inhibitory effects, with IC50 values ranging from 0.76 to 3.72 \u03bcM. Among them, compound 2 showed significant inhibitory effect, which significantly suppressed the production of IL-6, IL-1\u03b2, and iNOS in a concentration-dependent manner. The PC12 cells damage induced by H2O2 was attenuated by compounds 2, 10, 11, 13, 15, and 23. Moreover, compounds 2 and 11 delayed H2O2 induced damage, stabilized reactive oxygen species (ROS), mitochondrial membrane potential (MMP) and apoptosis expression levels.

They transmit the light information to the brain through complex circuits serving both non-image-forming and image-forming functions. Of the total population, there are four main ipRGCs, such as M2, M4, M5 and M6 that project substantially to the image-forming visual pathway and target the dorsal lateral geniculate nucleus (dLGN). Recent research has shown that they can modulate the excitatory and inhibitory balance in the primary visual cortex (V1) and thereby boost cortical computations for orientation discrimination. However, the projections of these ipRGCs to the V1 and how they integrate melanopsin signals with the conventional retinal ganglion cells is not yet clear. In this review, we summarize the morphological, physiological and behavioural characteristics of the ipRGC population that project to dLGN and contribute to image processing. Further research to understand how they can potentially enhance sensory representations in the visual cortex would offer therapeutic advantage in several eye diseases causing blindness.",

Aim of this review is to update the knowledge of Nrf2 as neuroprotective agent of PD. Activation of Nrf2, a transcription factor that regulates the expression of antioxidant and cytoprotective genes, has emerged as a promising therapeutic strategy for PD. Nrf2 is a master regulator of the cellular antioxidant response and is responsible for activating the expression of genes that encode antioxidant enzymes such as superoxidedismutase, catalase, and glutathione peroxidase. Pharmacological agents such as sulforaphane, curcumin, and resveratrol have been shown to activate Nrf2 and upregulate the expression of antioxidant genes in preclinical PD models. Clinical trials are currently underway to evaluate the efficacy of these pharmacological agents in patients with PD. While the neuroprotective role of Nrf2 in PD holds great promise for the development of novel therapies, there are several challenges and limitations that need to be addressed in order to harness the full potential of this pathway in the clinic. Overcoming these obstacles will require interdisciplinary collaborations, innovative research approaches, and a greater understanding of the complex pathophysiology of PD. By addressing these challenges, we can move closer to developing effective neuroprotective therapies that can slow or stop the progression of PD and improve the quality of life for patients with this devastating disease.",

Despite over a century of research, effective disease-modifying therapies remain elusive owing to its conundrum pathophysiology. In recent years, AD is increasingly recognised as a complex metabolic disorder characterised by impaired cerebral glucose metabolism, insulin resistance, and mitochondrial dysfunction. These interconnected metabolic disturbances emerge early in the disease state and collectively potentiate other pathologies such as accumulation of amyloid-\u03b2 (A\u03b2) plaques, tau hyperphosphorylation, oxidative stress, neuroinflammation, and synaptic dysfunction, thereby establishing bioenergetic failure as a primary factor governing AD progression rather than a downstream phenomenon. While traditional drug development strategies targeting A\u03b2 have failed in clinical trials (limited to monoclonal antibodies), emerging therapeutic models integrating energy failure, thiamine signalling, and insulin-like growth factor (IGF) signalling as upstream events show significant promise in countering downstream neurodegeneration. This chapter summarises the mechanistic framework linking bioenergetic breakdown to AD pathology, with potential therapeutic opportunities aimed at restoring mitochondrial function, enhancing glucose utilisation, and correcting insulin signalling, further opening new avenues for multimodal interventions and identification of progressive metabolic dysfunction biomarkers to aid diagnostic processes.",

Biflavonoids are predominant in the Order Cycadales (cycads). Among cycads, five Encephalartos species, E. ferox, E. kisambo, E. laurentianus, E. natalensis, and E. villosus, were selected to assess the neuroprotective potential by estimation of the antioxidant and acetylcholinesterase (AChE) inhibition activities. E. natalensis and E. ferox strongly inhibited AChE (IC50=1.349\u2009\u00b1\u20090.041 and 1.948\u2009\u00b1\u20090.06\u00a0\u00b5g/mL respectively), while E. kisambo and E. ferox were the most potent antioxidant. Accordingly, E. ferox was selected for further investigation. Chromatographic isolation of the ethyl acetate fraction afforded amentoflavone (1), bilobetin (2), ginkgetin (3), naringenin (6), and apigenin(7). The isolated biflavonoids (1-3) showed potent AChE inhibitory activity with IC50= 2.146\u2009\u00b1\u20090.086, 0.762\u2009\u00b1\u20090.039, and 1.474\u2009\u00b1\u20090.061\u00a0\u00b5g/mL respectively compared to rivastigmine, the positive control (IC50= 3.357\u2009\u00b1\u20090.103\u00a0\u00b5g/mL). A validated high-performance liquid chromatography with diode array detection (HPLC-DAD) method was developed for the simultaneous estimation of five biflavonoids: amentoflavone, bilobetin, ginkgetin, isoginkgetin and sciadopitysin in the five Encephalartos species and Ginkgo biloba. In addition, total phenolic and total flavonoid contents were estimated in the selected plants.

This makes it very important to find it early to stop vision loss. Manually evaluating retinal fundus images frequently necessitates considerable effort and is prone to observer-dependent discrepancies. To address these constraints, a new automated method for detecting glaucoma is presented. It combines fractal-inspired Sierpinski triangle spatial decomposition with multi-scale triangular segmentation to reliably identify clinically important areas of the retina. Handcrafted descriptors that include statistical, frequency-domain, wavelet, morphological, and texture-uniformity data are taken from small areas, giving a detailed and unique picture of the structures in the retina. A hybrid deep learning system that combines bidirectional LSTM, bidirectional GRU, and CNN with Bi-LSTM models that have attention layers captures spatial-temporal connections while highlighting essential visual cues for diagnosis. The Harris Hawks Optimizer, Grey Wolf Optimizer, Red Fox Optimizer, and Social Feature Optimizer are all examples of meta-heuristic algorithms that improve the feature subset. The HHO-based version gives the best results. A thorough examination using benchmark datasets shows that the system works very well, with 98.48% accuracy on Drishti-GS, 98.99% on Origa, 97.44% on RimOne-V2, 97.80% on HVD Binary-Class, 99.02% on HVD-Advance, 98.05% on HVD-Early, and 97.11% on HVD Multi-Class trials. The proposed system shows high reliability and stability in glaucoma diagnosis, delivering consistent performance across multiple datasets. It provides a scalable, non-invasive, and efficient solution for automatic detection, supporting doctors in early treatment and improving patients chances of recovery.",

Cumulative exposure was defined as reporting loneliness or social isolation at two time points (0, 1, or 2 times). In CHARLS (median follow-up: loneliness 4.90 years, social isolation 4.89 years; incident glaucoma cases: loneliness 185, social isolation 221), one-time loneliness (HR 1.49; 95% CI 1.01-2.20) and two-time loneliness (HR 1.99; 95% CI 1.39-2.86) were associated with a higher risk of self-reported incident glaucoma. Similar associations were observed for one-time social isolation (HR 1.47; 95% CI 1.01-2.15) and two-time social isolation (HR 1.77; 95% CI 1.14-2.76). In HRS (median follow-up: loneliness 4.86 years, social isolation 5.09 years; incident glaucoma cases: loneliness 566, social isolation 347), only two-time cumulative exposure was significantly associated with a higher risk of self-reported incident glaucoma: loneliness (HR 1.38; 95% CI 1.05-1.83) and social isolation (HR 1.30; 95% CI 1.01-1.66). These observational findings suggest that cumulative loneliness and social isolation may be relevant psychosocial markers for future eye-health research and should be interpreted as associative and hypothesis-generating.",

These processes lead to high mortality rates and long-term disabilities, imposing substantial socioeconomic burdens. Although reperfusion therapies have improved patient outcomes, many remain ineligible due to narrow therapeutic windows or clinical contraindications. Consequently, developing novel neuroprotective strategies is of significant clinical importance. Elamipretide (SS-31) and nicotinamide mononucleotide (NMN) are well-documented neuroprotective agents operating through distinct mechanisms; however, their combined efficacy and underlying mechanisms in ischemic stroke remain elusive. This study investigated the neuroprotective efficacy of SS-31 and NMN, alone or in combination, in a mouse model of ischemic stroke, with a specific focus on their modulation of triggering receptor expressed on myeloid cells 2 (TREM2)-mediated neuroinflammatory and apoptotic pathways. A middle cerebral artery occlusion/reperfusion (MCAO/R) model was established in male mice, followed by treatment with SS-31, NMN, or their combination. Therapeutic outcomes were evaluated using neurobehavioral scoring, histopathological staining, transcriptomic sequencing, and protein expression analyses. TREM2 overexpression experiments and specific pharmacological inhibition of the NF-\u03baB pathway were conducted to elucidate the specific molecular mechanisms. Co-administration of SS-31 and NMN significantly attenuated post-ischemic brain damage and ameliorated neurological deficits (P\u2009<\u20090.0001), demonstrating effects markedly superior to either monotherapy. Transcriptomic profiling revealed that the combination therapy specifically modulated innate immune and apoptotic pathways, concomitant with a significant downregulation of TREM2. Mechanistically, the combination therapy effectively inhibited NF-\u03baB (p65) activation, thereby downregulating TREM2 expression. This suppression attenuated microglial activation, reduced the expression of canonical pro-inflammatory cytokines (IL-1\u03b2, TNF-\u03b1, and IL-6), and rebalanced the Bcl-2/Bax apoptotic axis. Overexpression of TREM2 entirely reversed these neuroprotective benefits. Combination therapy with SS-31 and NMN provides robust neuroprotection against ischemic stroke by suppressing the NF-\u03baB/TREM2 signaling axis, thereby combinatorially modulating post-stroke neuroinflammation and apoptosis. These findings highlight a novel, multi-targeted strategy for precision stroke interventions.",

While minimally invasive glaucoma surgery (MIGS) has focused attention on enhancing conventional outflow, increasing evidence suggests that the sclera represents a biologically active and potentially modifiable interface influencing unconventional aqueous drainage and transscleral drug delivery. Traditionally regarded as a passive structural barrier, the sclera is now recognized as a spatially heterogeneous, mechanosensitive tissue with region-specific extracellular matrix composition and biomechanical properties. Emerging data demonstrate that pharmacologic agents such as prostaglandin analogues can remodel scleral extracellular matrix architecture, increasing molecular permeability and facilitating uveoscleral outflow. At the same time, advances in transscleral drug delivery including iontophoresis, ultrasound-assisted diffusion, biodegradable matrices, and extracellular vesicle-based platforms highlight the sclera's dual role as both a hydraulic regulator and a therapeutic conduit. However, translational challenges including diffusion-dominated transport, episcleral clearance, fibrotic encapsulation, and dose variability have, to date, limited the widespread clinical adoption of transscleral strategies. In this review, we synthesize structural, biomechanical, pharmacologic, and translational evidence to propose a refined framework: the sclera as a dynamically remodeling hydraulic interface that may be selectively modulated to influence aqueous outflow and enable targeted posterior segment delivery. This integrative perspective expands the therapeutic paradigm for glaucoma beyond trabecular intervention alone.",

This study aims to evaluate the therapeutic potential of GSPE against PWMI and the underlying mechanisms. GSPE (20\u00a0mg/Kg) was taken orally by the mouse after PWMI modeling. The survival rate, incidence of macroscopic lesions, body weight change were calculated. The myelin damage was evaluated. Mitochondrial homeostasis\u200c was detected in PWMI model mice and cultured oligodendrocyte precursor cells (OPCs). Brain tissues from mice groups underwent RNA-seq.\u00a0A dual-luciferase reporter assay was employed to validate the direct binding interaction between miR-153 and IMMP2L mRNA. The results showed that treatment of GSPE ameliorated cerebral ischemic injury in PWMI mice and improved behaviour ability and cognition deficits. GSPE restored mitochondria homeostasis in both PWMI mice and OPCs. Additionally, IMMP2L was found to be increased, while ROS was diminished by GSPE intervention. KEGG analysis showed that Wnt signaling pathway, the downstream of IMMP2L, changed significantly in PWMI group, while GSPE reversed it. The dual-luciferase reporter assay demonstrated that miR-153-3p directly suppressed IMMP2L expression through these binding sites. In summary, our findings revealed that GSPE treatment alleviated PWMI and restored mitochondrial homeostasis in mice.These beneficial effects are likely be attributed to the improvement of the activity of IMMP2L-related signaling pathways by GSPE.",

In Japan, DPP-4 inhibitors have been widely used, but since 2022 the pharmacotherapy algorithm has shifted: DPP-4 inhibitors and biguanides for BMI < 25 kg/m   2  , and biguanides and SGLT2 inhibitors for BMI \u2265 25 kg/m   2  . However, real-world factors influencing prescribing decisions between biguanides and SGLT2 inhibitors remain unclear. This study investigates factors influencing the choice between biguanides and SGLT2 inhibitors in clinical practice. We also compare glycemic efficacy and medication persistence while accounting for baseline characteristics. This retrospective cohort study used the Millennium Medical Record Database, primarily capturing care from large hospitals. Adults aged \u2265 18 years who received a first prescription of a biguanide or a SGLT2 inhibitor between July 2019 and April 2023 were included. Patients were categorized as 1st-line or 2nd-line therapy. Confounding was addressed using coarsened exact matching with classification tree modeling. HbA1c changes were analyzed using mixed models for repeated measures, and persistence using Kaplan-Meier methods. A total of 1925 patients were included. In the 1st-line cohort (n\u00a0=\u00a01440), key selection factors were diuretic use, lipid-modifying agents, and baseline HbA1c. At 24 weeks, HbA1c decreased in both groups (biguanide: -1.37 percentage points, 95% CI -1.48 to -1.26; SGLT2 inhibitor: -1.16 percentage points, 95% CI -1.29 to -1.02); the between-group difference was -0.21 percentage points (95% CI -0.38 to -0.04). Persistence at 48 weeks was 47.0% (95% CI 42.7-51.2) for biguanides and 56.2% (95% CI 51.2-61.2) for SGLT2 inhibitors. In the 2nd-line cohort (n\u00a0=\u00a0485), selection factors were baseline HbA1c, BMI, and diuretic use. HbA1c decreased at 24 weeks (biguanide: -2.26 percentage points, 95% CI -2.47 to -2.05; SGLT2 inhibitor: -1.79 percentage points, 95% CI -2.04 to -1.54); the between-group difference was -0.47 percentage points (95% CI -0.80 to -0.15). Persistence at 48 weeks was 51.8% (95% CI 45.2-58.4) for biguanides and 49.4% (95% CI 40.3-58.6) for SGLT2 inhibitors. In Japanese patients with type 2 diabetes, treatment selection was mainly associated with concomitant cardiovascular medication use. BMI influenced choice, particularly in the 2nd-line setting, but was not the predominant determinant. Biguanides were associated with greater HbA1c reductions. In intention-to-treat analyses, persistence over 48 weeks was higher with SGLT2 inhibitors in the 1st-line cohort, while persistence was comparable in the 2nd-line cohort.",

Despite its impact, therapeutic strategies remain disproportionately conservative, often delaying effective intervention. In contrast, treatment algorithms for other chronic diseases, such as type 2 diabetes and rheumatoid arthritis, have adopted remission-oriented approaches aimed at suppressing disease activity rather than merely attenuating progression. In this context, we propose a remission-oriented paradigm for obesity. Remission is defined as a sustained, multidimensional state characterized by the achievement of clinically meaningful adiposity targets, alleviation of obesity-related complications, restoration of functional capacity, and improvement in psychological well-being. Importantly, remission is conceptualized as a continuum, analogous to glycemic states, and may be maintained with ongoing pharmacotherapy. We further propose an induction-remission-maintenance model that prioritizes early, effective intervention. This framework explicitly acknowledges the chronic nature of the disease of obesity, even in the presence of potent therapies, underscoring the need for ongoing monitoring and long-term disease surveillance. Despite challenges related to access, cost, and long-term adherence, this approach offers a structured, disease-centered model with the potential to improve clinical outcomes and reduce healthcare burden.",

Contemporary obesity pharmacotherapies extend beyond weight reduction, with evidence for improvements across multiple obesity-related complications, supporting a shift toward phenotype-guided, complication-centric care. A systematic literature search of the Medline database using MeSH terms and keywords related to new-generation obesity pharmacotherapy was conducted to identify articles published between 2021 and 2026. Reference lists of relevant reviews were screened to identify additional eligible studies. Phase 2 and 3 clinical trials evaluating emerging obesity pharmacotherapies in adults and reporting outcomes, including weight loss and obesity-related complications, were included. Entero-pancreatic hormone-based therapies targeting GLP-1, GIP, amylin, and glucagon pathways demonstrate substantial efficacy beyond weight reduction. These hormones act through complementary mechanisms regulating appetite, energy balance, and metabolic homeostasis. GLP-1 based agents achieve approximately 10-15% weight loss, whereas agents targeting multiple pathways demonstrate greater efficacy. Tirzepatide, CagriSema, and amycretin achieved weight reductions exceeding 20% and the triple agonist retatrutide produced reductions exceeding 25%. Beyond weight loss, these agents improve glycemia, support diabetes prevention, and produce organ-specific benefits, including reduced cardiovascular events, improved heart failure symptoms, decreased obstructive sleep apnea severity, improvement of metabolic dysfunction-associated steatohepatitis, slowing chronic kidney disease progression, and reduced osteoarthritis-related pain. Next-generation obesity pharmacotherapies represent a major advance in obesity management and support a treat-to-target approach prioritizing improvement in obesity-related complications and metabolic health. Effective implementation will require individualized therapy and attention to long-term safety, access, and equitable delivery of care.",

It can lead to significant cognitive impairment, neurological deficits, and increased mortality. As radiotherapy techniques advance and patient survival improves, effective prevention and management of RBN have become critical clinical priorities. This review systematically summarizes the current understanding of RBN pathogenesis, highlighting the central roles of vascular injury (endothelial damage, HIF-1\u03b1/VEGF dysregulation) and neuroinflammation (microglial activation, cytokine release). We discuss recent advances in preventive strategies, including refined radiotherapy modalities such as intensity-modulated radiotherapy (IMRT), fractionated stereotactic radiosurgery (fSRS), and FLASH ultra-high-dose-rate radiotherapy, as well as pharmacological prophylaxis using bevacizumab and neuroprotective agents (NGF, GM1, edaravone). Established and emerging treatment options are reviewed, including corticosteroids, bevacizumab, hyperbaric oxygen therapy (HBOT), laser interstitial thermal therapy (LITT), and Colony Stimulating Factor 1 Receptor(CSF1R) inhibitors.

This retrospective case series included 15 patients (25 eyes) with POAG who underwent GATT at the Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Chengdu University of Traditional Chinese Medicine, between January 2019 and January 2022 and completed pre- and postoperative 24-h IOP monitoring. Postoperative monitoring was performed at 3-6 months after surgery, after IOP-lowering medications had been discontinued for at least 7 days. Patients were followed for 2 years. Outcomes included pre- and postoperative 24-h IOP parameters, office IOP and medication burden at baseline and 2 years, and gonioscopic findings. The 24-h IOP peak decreased significantly from 26.16 \u00b1 1.44 mmHg preoperatively to 21.16 \u00b1 0.60 mmHg postoperatively (mean \u00b1 SD; P = 0.001). The trough IOP decreased from 17.52 \u00b1 0.66 mmHg to 16.25 \u00b1 0.42 mmHg (mean \u00b1 SD; P = 0.098). IOP fluctuation decreased significantly from 8.68 \u00b1 0.98 mmHg to 4.91 \u00b1 0.34 mmHg (mean \u00b1 SD; P < 0.001). Mean office IOP decreased from 21.58 \u00b1 1.03 mmHg at baseline to 18.45 \u00b1 0.51 mmHg at 2 years (mean \u00b1 SD; P = 0.005), while the median number of medications decreased from 3 (2, 4) to 0 (0, 1). Gonioscopy showed no significant change in Spaeth angle grading across quadrants. Peripheral anterior synechiae were significantly more frequent postoperatively in the nasal and temporal quadrants, while trabecular meshwork pigmentation grade changed significantly in the nasal, temporal, and superior quadrants. In this small retrospective case series of POAG eyes, GATT was associated with reductions in 24-h IOP peak and fluctuation, sustained office IOP lowering, and marked medication reduction. Gonioscopy showed stable overall angle configuration, more frequent postoperative PAS in the nasal and temporal quadrants, and postoperative changes in trabecular meshwork pigmentation grade in some quadrants. These findings should be interpreted cautiously and confirmed in larger prospective studies.",

The disorder often produces a distinctive \"shredded wheat\" appearance from iris fibers floating in the anterior chamber, and it commonly coexists with angle-closure glaucoma and cataracts. We present two cases where combined surgical management proved effective. The first case was an 81-year-old woman with bilateral iridoschisis complicated by cataract. Following laser peripheral iridotomy (LPI), gonioscopic examination indicated continued angle closure. Combined phacoemulsification and goniosynechialysis surgery achieved normalized IOP and visual improvement through 18-month follow-up. The second patient was an 82-year-old man with bilateral iridoschisis and narrow angles. The first eye underwent standard cataract surgery. When operating on the second eye, intraoperative gonioscopy identified peripheral anterior synechiae, leading us to add goniosynechialysis. Postoperatively, both eyes showed excellent visual outcomes and stable IOP. For iridoschisis patients, the dual procedure of phacoemulsification and goniosynechialysis addresses two problems simultaneously: the cataract and the anatomical cause of angle closure. The combination thus offers a practical solution for complex iridoschisis cases.",

Particular emphasis was placed on evaluating whether BHD pretreatment could prevent or attenuate hypobaric hypoxia-induced neurological dysfunction and hippocampal injury, and on clarifying its potential mechanisms from the perspectives of inflammatory responses, metabolic regulation, and HIF-1/PI3K-Akt-related pathways. A mouse model of hypobaric hypoxia-induced brain injury was established by exposure to a simulated high-altitude hypoxic environment equivalent to an altitude of 6000\u00a0m for 72\u00a0h. Mice were assigned to the normal control, model, BHD-pretreated, and acetazolamide-positive control groups. BHD and acetazolamide were administered once daily by intragastric gavage, starting 4 days before hypobaric hypoxia exposure and continuing during the 72\u00a0h exposure period. Open field testing was performed to assess spontaneous locomotor activity and exploratory behavior. Hippocampal injury was evaluated by hematoxylin and eosin staining, Nissl staining, and HIF-1\u03b1 immunofluorescence staining. Non-targeted serum metabolomics, network pharmacology, hippocampal transcriptomics, and RT-qPCR validation were integrated to explore the potential mechanisms of BHD pretreatment. BHD pretreatment prevented hypobaric hypoxia-induced behavioral abnormalities and alleviated hippocampal pathological injury, neuronal loss, and Nissl body reduction. BHD also reduced excessive hippocampal HIF-1\u03b1 expression. Multi-omics analyses suggested that the protective effect of BHD was associated with the regulation of inflammatory responses, metabolic disturbances, and HIF-1/PI3K-Akt-related signaling. RT-qPCR validation showed that BHD modulated the abnormal expression of HIF-1\u03b1, IL-6, VEGFA, NF-\u03baB1, and STX1A in hippocampal tissue. BHD exerts a preventive neuroprotective effect against hypobaric hypoxia-induced brain injury in mice. Its effects may involve coordinated regulation of hypoxic responses, inflammatory signaling, metabolic remodeling, and HIF-1/PI3K-Akt-related pathways.",

Importantly, growing efforts are directed toward disease-modifying therapies, including \u03b1-synuclein immunotherapy, inhibitors of protein misfolding and aggregation, glucocerebrosidase-targeted interventions, and neuroprotective agents that modulate mitochondrial dysfunction, oxidative stress, inflammation, and metabolic signaling. Although many candidates have shown encouraging preclinical or early clinical results, definitive disease-modifying efficacy remains to be established. This review summarizes recent progress in PD pharmacotherapy, highlights translational challenges, and discusses future directions toward precision medicine and combination strategies for achieving sustained symptomatic control and disease modification.",
        "42445281": "ID: 42445281\nTitle: Advances in research on pharmacological mechanisms of anatabine: from nicotinic modulation to multitarget therapeutic potential.\nAbstract: Anatabine, a characteristic minor alkaloid derived from tobacco byproducts, exhibits unique structural analogy to nicotine but possesses a superior safety profile and lower addictive liability, rendering it a promising natural multi-target therapeutic candidate. Accumulating preclinical evidence has demonstrated that anatabine exerts neuroprotective, anti-inflammatory, and antioxidant effects mainly through modulating \u03b17/\u03b14\u03b22 nicotinic acetylcholine receptors, suppressing NF-\u03baB/STAT3 inflammatory signaling, and activating the Nrf2-mediated antioxidant pathway. It effectively ameliorates typical pathological alterations, including \u03b2-amyloid deposition, tau hyperphosphorylation, and microglial overactivation, thereby improving cognitive and behavioral deficits in neurodegenerative disease models. Additionally, anatabine displays broad pharmacological potentials in chronic inflammation, autoimmune thyroiditis, asthma, and hypertension. Differing from previous reviews that merely focused on single receptor regulation, the present work systematically summarizes the multi-target pharmacological characteristics of anatabine, comprehensively collates its preclinical efficacy across multiple disease categories, and highlights its advantages over nicotine in safety and addiction risk. Furthermore, we analyze the current limitations, druggability optimization challenges, and clinical translation prospects, and propose sustainable strategies for high-value utilization of tobacco byproducts. This review provides an updated and systematic theoretical basis for further mechanism exploration and therapeutic development of anatabine.",

We investigated whether a biomarker-based metabolic vulnerability index (MVX) was associated with incident age-related ocular diseases and whether joint consideration of MVX and genetic susceptibility may help characterize relative risk patterns. A prospective population-based cohort of 206,311 participants from the UK Biobank was analyzed. MVX was evaluated as the primary exposure. Incident age-related macular degeneration (AMD), cataract, diabetic retinopathy (DR), and glaucoma were ascertained as outcomes. Associations were examined using Cox proportional hazards models, with hazard ratios (HRs) and 95% confidence intervals (CIs) estimated per 1-standard deviation (SD) increase in MVX. As secondary exploratory analyses, polygenic risk score (PRS) analyses were performed to explore whether metabolic vulnerability and genetic susceptibility jointly characterized relative risk patterns. During follow-up, 4,144 participants developed AMD, 13,574 cataract, 1,483 DR, and 5,525 glaucoma. After multivariable adjustment for demographic, socioeconomic, clinical, and lifestyle factors, each 1-SD increase in MVX was associated with higher risks of incident AMD (HR = 1.07; 95% CI: 1.03-1.11), cataract (HR = 1.04; 95% CI: 1.02-1.06), and DR (HR = 1.11; 95% CI: 1.05-1.18), whereas no significant association was observed for glaucoma (HR = 1.00; 95% CI: 0.97-1.03). In joint analyses, individuals with both high genetic risk and elevated MVX exhibited the greatest risks of AMD (HR = 2.32; 95% CI: 2.01-2.67), cataract (HR = 1.62; 95% CI: 1.49-1.76), and DR (HR = 3.84; 95% CI: 2.91-5.06), compared with those with low genetic risk and low MVX. These findings suggest that MVX may be relevant to population-level patterns of risk for several age-related eye diseases. However, further studies are needed to determine whether MVX provides meaningful predictive value or clinical utility beyond conventional risk factors.",

A 40-year-old intravenous drug user was presented to the emergency department after injuring his right eye with a used hypodermic needle 4 days previously. Slit-lamp examination revealed an intense anterior segment reaction with corneal edema, limiting the view to deeper structures. UBM allowed lens visualization, which demonstrated a crescent hyperechoic anterior subcapsular shadow, which was not present in the fellow eye. As the anterior segment inflammation and corneal edema cleared with topical steroid treatment and antibiotic treatment, the traumatic cataract, posterior synechiae, and lens particles in the anterior chamber became evident. A review of published literature demonstrated a similar sign of crescent hyperechoic anterior subcapsular shadow that has been documented in two previous cases with disrupted anterior capsules and lens-particle glaucoma. UBM can be used for assessing anterior lenticular integrity and may aid in diagnosing lenticular injuries where a direct view is impossible. Lens crescent sign is a UBM finding that suggests lenticular injuries.",

It involves microglia, astrocytes, and cytokines. The aim of this study was to investigate the effects of neuroprotectors on morphology of microglial cell during lipopolysaccharide (LPS)-induced neuroinflammation. Immunocytochemical detection of microglia using the IBA1 marker in glial cell cultures obtained from rat cerebral cortex revealed the presence of a significant number of microglial cells in the studied culture. In the control, microglial cells possessed a large number of processes typical of nonactivated cells. In cultures treated with LPS (10 \u03bcg/ml, 24 h), microglia had a flattened amoeboid morphology, characteristic of activated cells. Furthermore, LPS treatment also resulted in an increase in the profile field area of the cell body, while the perimeter did not increase significantly, indicating a more rounded cell body shape compared to the control. In cultures treated with methylene blue (1 \u03bcM, 24 h) in the presence of LPS, microglial cells had a larger number of processes and a smaller body profile area than microglia treated with LPS alone, and their perimeter did not differ significantly from that of control cells. In the case of menadione (1 \u03bcM, 24 h) in the presence of LPS, the cells retained an amoeboid shape, and their size did not change significantly compared to the LPS group. Microglia treated with methylene blue alone did not differ from control microglia in morphology, body profile area, or perimeter, whereas menadione caused a significant increase in the cell's body profile area and a shift in their morphology toward an activated phenotype. Methylene blue, a substance whose anti-inflammatory action is associated with Nrf2 activation, is capable of not only reducing the production of proinflammatory cytokines but also preventing the transition of microglia to the activated phenotype.",

However, many existing endotamponades tend to disperse or fragment during injection, making it difficult to form a stable structure within the vitreous cavity and thereby severely limiting their functional performance and clinical applicability. Consequently, the development of injectable endotamponades with controlled viscosity and in situ gelation remains a critical challenge. In this study, we present an injectable polyethylene glycol (PEG) hydrogel incorporating high-molecular-weight hyaluronic acid (HA), designed to mimic key physicochemical features of the human vitreous. The hydrogel forms a three-dimensional network via covalent crosslinking between eight-arm PEG-thiol (8sPEG-SH) and eight-arm PEG-maleimide (8sPEG-MAL), while incorporating high-molecular-weight HA enables viscosity regulation and imparts vitreous-like mechanical properties. The hydrogel exhibits a storage modulus of 15 Pa and an adjustable in situ gelation time of approximately 3 minutes, together with good optical transparency, appropriate surface tension, and a low swelling ratio. In vivo studies in rabbit eyes further demonstrate that the hydrogel can be smoothly injected and subsequently form a stable structure within the vitreous cavity, confirming its practical operability for intraocular application. This work introduces a tunable PEG hydrogel system with controllable in situ gelation via a double-chamber syringe, offering a new strategy for preliminary evaluation of vitreous substitutes with favorable intraocular biocompatibility.",

Using distributed lag non-linear models (DLNM), the study first analyzed air pollution and temperature data in Shenyang (2013-2021), revealing that ambient temperature did not show significant short-term effects on glaucoma incidence. In contrast, NO2 was significantly associated with short-term increases in glaucoma risk, particularly within a few days following exposure. PM2.5 demonstrated short-term effects, with a stronger risk observed during colder months, when pollutant levels were elevated. PM10 also exhibited a delayed impact on glaucoma risk, although its effect was less pronounced. Further analysis using CHARLS data confirmed these findings, with long-term exposure to PM2.5 and NO2 associated with higher odds and hazard of developing glaucoma, especially among smokers. To assess causality, Mendelian randomization analyses provided genetic evidence that genetically predicted exposure to PM2.5 (IVW OR\u2009=\u20091.367) and NO\u2082 (IVW OR\u2009=\u20091.463) were causally linked to an increased risk of glaucoma. The study found no significant causal association with PM10 or workplace (indoor) temperature exposure. Overall, this study underscores the critical role of air pollution, particularly PM2.5 and NO2, in glaucoma risk. It highlights the importance of environmental policies aimed at improving air quality, particularly for vulnerable populations such as smokers, and suggests further investigation into the underlying biological mechanisms of pollutant-induced glaucoma.",

A retrospective study was conducted on 30 eyes of 28 patients with aphakic glaucoma who underwent implantation of PGI (n\u2009=\u200910) or AGV (n\u2009=\u200920). Primary outcomes included surgical failure and success (complete or qualified). Secondary outcomes included intraocular pressure (IOP) reduction, best-corrected visual acuity (BCVA), medication use, and postoperative complications. Kaplan-Meier survival analysis was applied, with failure defined as IOP\u2009>\u200921 mmHg on two consecutive visits, implant removal, additional glaucoma surgery, or vision loss. At 12 months, surgical success was achieved in 90% of PGI eyes and 75% of AGV eyes (p\u2009=\u20090.766). Complete success occurred in 30% (PGI) and 25% (AGV), while failure occurred in one PGI eye and five AGV eyes. Kaplan-Meier analysis revealed comparable cumulative success rates (p\u2009=\u20090.475). Mean IOP at 12 months was similar between groups (16.0 vs. 16.4 mmHg; p\u2009=\u20090.854), with significant reductions from baseline (PGI: p\u2009=\u20090.002; AGV: p\u2009<\u20090.001). Both groups showed reduced medication burden (p\u2009<\u20090.001), with PGI requiring fewer agents at 1-2 months (p\u2009=\u20090.024). BCVA remained stable. One complication was recorded, a case of choroidal haemorrhage in the AGV group; the hypotony episode was not classified as a complication as it resolved without visual loss or further surgical intervention.). PGI and AGV both effectively managed aphakic glaucoma. PGI demonstrated a trend toward higher success rates and fewer complications; however, these differences were not statistically significant. These findings suggest that PGI may be a favourable alternative, although larger prospective studies are needed to confirm this potential advantage.",

Despite decades of intensive investigation, existing therapeutic options provide only modest symptomatic relief and fail to prevent or slow disease progression, emphasizing the critical need for interventions that target the fundamental molecular mechanisms of neurodegeneration. Pathologically, Alzheimer's disease is characterized by extracellular accumulation of amyloid-\u03b2 plaques, intracellular neurofibrillary tangles formed by hyperphosphorylated tau, profound synaptic loss, chronic neuroinflammation, and extensive neuronal degeneration. Although amyloid-focused strategies have long dominated drug development, their limited clinical benefit and safety liabilities highlight the multifactorial nature of AD and the need to move beyond amyloid-centric paradigms. Protein kinases have emerged as key integrators of multiple pathogenic processes in AD, governing tau phosphorylation, amyloid precursor protein processing, synaptic signaling, and neuroimmune responses. Aberrant kinase signaling drives tau pathology and propagation, promotes amyloidogenic pathways, disrupts synaptic function, and perpetuates inflammatory cascades. While extensive work on kinases such as GSK-3\u03b2, CDK5, JNKs, and CSF1R has firmly established the relevance of kinase dysregulation in AD, no kinase-directed therapy has yet translated into clinical success. This review highlights emerging kinase targets beyond these classical pathways, including Fyn, Casein Kinase 1 Delta (CK1\u03b4), Tau-Tubulin Kinase 1 (TTBK1), and Dual Leucine Zipper Kinase (DLK), which are supported by mechanistic insights and compelling preclinical evidence. Continued advances in brain-penetrant, isoform-selective, and mechanism-driven kinase inhibitor design may enable the development of next-generation disease-modifying therapies for Alzheimer's disease.",

A retrospective case review including best-corrected visual acuity (BCVA), color vision testing, fundus photography, spectral-domain optical coherence tomography (SD-OCT), full-field electroretinography (ERG), and next-generation sequencing with parental segregation analysis. Variant pathogenicity was assessed using in-silico prediction models (PolyPhen-2 HumDiv and HumVar), and findings were integrated with clinical and imaging data. A sixteen-year-old male reported lifelong nyctalopia and stable difficulty seeing in dim. BCVA was 20/30 OD and 20/25 OS with normal color vision. Fundus examination revealed multiple white-yellow flecks along the arcades and mid-periphery with macular sparing. SD-OCT demonstrated preserved outer retinal architecture and an intact ellipsoid zone, and full-field ERG showed preserved rod and cone responses. Genetic testing identified two RPE65 missense variants: c.433G>A (p.Ala145Thr), likely pathogenic, and c.946A>G (p.Asn316Asp), reported as a VUS. PolyPhen-2 analysis classified p.Asn316Asp as damaging (HumDiv/HumVar score 1.000), and parental segregation demonstrated the variants in trans. Integration of genotype and phenotype supports p.Asn316Asp as likely pathogenic. Compound heterozygosity for hypomorphic RPE65 variants can produce a stationary fundus albipunctatus-like phenotype rather than progressive retinal degeneration. Careful integration of multimodal phenotyping and variant interpretation was essential for confirming disease causality.",

However, its effects on pentylenetetrazole (PTZ)-induced seizure and associated oxidative brain damage remain unclear. To evaluate the anticonvulsant effects of nerolidol on PTZ-induced seizures in mice and to investigate its impact on oxidative and nitrosative stress markers in the hippocampus and cortex. Male mice were divided into 5 groups: control, PTZ, and PTZ pretreated with nerolidol (25, 50, or 100\u2009mg/kg, orally) 30\u2009minutes before PTZ administration. Seizure activity was assessed by measuring latencies to minimal clonic seizures (MCSs) and generalized tonic-clonic seizures (GTCSs). After a behavioral evaluation, hippocampal and cortical tissues were analyzed for malondialdehyde (MDA), nitric oxide (NO) metabolites, superoxide dismutase (SOD), catalase (CT), and total thiol content. Nerolidol significantly increased MCS and GTCS latencies compared with the PTZ group. In the hippocampus, all doses reduced MDA levels, while in the cortex this effect was observed at 50 and 100\u2009mg/kg. Nitric oxide metabolites were decreased by the two higher doses in both brain regions. The PTZ-induced reductions in SOD and CT activities were reversed by nerolidol at all doses, and total thiol levels were restored at 50 and 100\u2009mg/kg. Nerolidol exhibits anticonvulsant and neuroprotective effects on PTZ-induced seizures, likely mediated by reduced oxidative and nitrosative stress and enhancement of endogenous antioxidant defenses.",

In China, due to population aging, lifestyle changes, and advances in medical diagnostic technology, the incidence and detection rate of DR have been increasing year by year. Therefore, exploring effective management and follow-up models for DR is of paramount importance in reducing the blindness rate caused by DR and improving the quality of life of patients. Based on the KPAI theory, a questionnaire for postoperative follow-up needs of patients with diabetic retinopathy was developed to determine the effectiveness of the questionnaire. The content of intelligent follow-up was adjusted based on the results of the needs questionnaire survey, and the changes in disease knowledge, physical, psychological, and social aspects of postoperative follow-up patients were evaluated. A total of 1372 patients with diabetic retinopathy who received treatment in our hospital's wards from January 2023 to December 2023 were selected. Among them, 278 patients underwent a postoperative follow-up needs survey, with 347 patients undergoing routine follow-up and 445 patients undergoing intelligent follow-up, with a follow-up time of one week after surgery. In the first participation of patients in intelligent follow-up, 20 patients were randomly selected for follow-up one month and three months after surgery to assess changes in patient indicators. The scale finally determined 16 items, including information acquisition, postoperative self-management, psychological emotions, and social integration, with a Cronbach's \u03b1 coefficient of 0.662, I-CVI range of 0.714 to 1, and an S-CVI value of 0.929.

Delicaflavone, a natural biflavonoid, possesses antioxidant, anti-inflammatory, and neuroprotective effects; however, its neuroprotective potential against rotenone-induced Parkinson's disease warrants exploration. To induce Parkinson's disease in rats, 0.5\u00a0mg/kg of rotenone was administered subcutaneously for 28\u00a0days, and delicaflavone was administered orally at different doses (10, 20, and 40\u00a0mg/kg). In addition to behavioral tests, neurochemical parameters, oxidative stress, mitochondrial function, inflammatory cytokines, and apoptosis were assessed. Delicaflavone treatment increased square-crossed activity and rotarod performance and reduced catalepsy time.

Ficus deltoidea (FD), a medicinal plant rich in flavonoids vitexin and isovitexin, possesses potent antioxidant and anti-inflammatory properties, yet its neuroprotective efficacy in AD remains incompletely characterized. This study investigated the protective effects of FD in a D-galactose- and aluminum chloride (AlCl3)-induced oxidative stress-driven AD-like rat model using behavioral, histological, ultrastructural, and biochemical approaches. Fifty-four male Wistar rats were assigned to six groups: control, AD-like model, donepezil (1\u00a0mg/kg), and FD-treated groups (50, 100, and 200\u00a0mg/kg) for 10\u00a0weeks. Anxiety-like behavior and spatial working memory were assessed using the elevated plus maze (EPM) and T-maze tests, respectively. Hippocampal neuronal integrity was evaluated by hematoxylin and eosin (H&E) staining and transmission electron microscopy (TEM), while oxidative stress biomarkers (MDA, CAT, T-SOD, CuZn-SOD, and HO-1) were quantified using ELISA. FD treatment, particularly at 200\u00a0mg/kg, significantly improved spatial working memory and normalized anxiety-related behavior, with treatment responses approaching those observed in the donepezil-treated group. Histological analyses revealed preservation of pyramidal neurons across CA1, CA2, CA3, and dentate gyrus subregions, while ultrastructural studies demonstrated marked protection of mitochondrial integrity, myelin sheath organization, and smooth endoplasmic reticulum morphology. Biochemically, FD significantly reduced lipid peroxidation and enhanced endogenous antioxidant defenses. In conclusion, FD exerted significant neuroprotective effects characterized by preservation of hippocampal structure, maintenance of neuronal ultrastructure, and restoration of redox homeostasis in an oxidative stress-driven AD-like model. These findings demonstrate that FD mitigates oxidative stress-associated neuronal injury and cognitive impairment in a D-galactose and AlCl3-induced AD-like rat model, supporting its potential as a phytotherapeutic candidate for oxidative stress-related neurodegeneration. However, further studies are required to determine its effects on canonical Alzheimer's disease pathologies, including amyloid and tau abnormalities.",

Methylglyoxal (MG), a highly reactive dicarbonyl compound and precursor of advanced glycation end products, contributes to oxidative stress, tau hyperphosphorylation and amyloid-\u03b2 (A\u03b2) accumulation, which are key events linking diabetes to Alzheimer's disease. In this study, an acetylated derivative of nobiletin, 5-acetoxy-6,7,8,3',4'-pentamethoxyflavone (5-AN), was evaluated for its neuroprotective and gut microbiota-modulating effects against MG-induced Alzheimer-like cognitive deficits in mice. Oral administration of 5-AN (10 and 20\u2009mg\u2009kg-1\u2009day-1 for 13\u2009weeks) improved behavioral performance in MG-treated mice, with the 20\u2009mg\u2009kg-1 group showing significant improvement in spatial learning, recognition memory and anxiety-like behavior. Immunohistochemical and Western blot analyses showed that 5-AN reduced hippocampal tau phosphorylation and A\u03b2 accumulation at the same time as restoring phosphoinositide 3-kinase (PI3K)/Akt/glycogen synthase kinase-3\u03b2 signaling, enhancing brain-derived neurotrophic factor expression and reducing cleaved caspase-3 expression. Gut microbiota analysis showed that MG exposure induced dysbiosis, characterized by reduced Bacteroides_H acidifaciens and increased MG-associated taxa such as Alistipes and Dysosmobacter, whereas 5-AN supplementation significantly reversed these alterations. Functional prediction analysis further indicated that MG-induced dysbiosis was associated with disruptions in neuroimmune-related pathways, including circadian entrainment, Th17 cell differentiation, interleukin-17 signaling and PI3K/Akt signaling, whereas 5-AN supplementation significantly restored these pathways. These findings indicate that acetylated nobiletin may serve as a promising food-derived bioactive compound for mitigating cognitive impairment through coordinated modulation of neuronal function and gut microbiota. \u00a9 2026 Society of Chemical Industry.",

Vessel detection using deep-learning approaches could enable more objective measures. We aimed to evaluate vascular metrics derived from automated vessel detection and compare these metrics with manual severity gradings. Methods: Slit lamp images from 139 glaucoma patients were included. Images from 103 participants were used as the primary development dataset and the remaining as a validation subset. The images were independently graded by two graders for conjunctival hyperemia using the Efron Grading Scheme. Conjunctival vessels were detected using an automated vessel detection pipeline based on semi-supervised learning. Vessel density, fractal dimension and tortuosity were calculated and compared with the manual Efron grades. Results: Grading of conjunctival hyperemia between the two graders were consistent (Spearman's rho: 0.79; ICC: 0.79 [95%CI: 0.72-0.84]) but showed significant differences with a higher proportion of differences in the moderate grades. Of the vascular metrics, vessel density showed significant associations with the individual Efron grading and against the mean Efron grading (0.78, p < 0.001). Fractal dimension was significantly associated with the mean Efron grading (0.55, p < 0.001). Agreements were similar in the subset (vessel density, 0.80, p < 0.001; fractal dimension 0.62, p < 0.001). Vessel tortuosity showed lower agreements (<0.23). Conclusions: Vessel density and fractal dimension showed significant associations with manual Efron gradings. These metrics could be potentially used to enable more objective and interpretable measures of conjunctival hyperemia severity.",

Given the limited efficacy of conventional chemotherapy in this setting, alternative targeted therapeutics are needed. Mirvetuximab soravtansine (MIRV) is an antibody-drug conjugate designed to deliver the cytotoxic maytansinoid DM4 to folate receptor alpha (FR\u03b1)-overexpressing cells. This systematic review of PubMed, ClinicalKey, and SpringerLink databases (2019-2026) evaluates five publications across three clinical trials (one phase II, two phase III) encompassing 925 patients with platinum-resistant disease. Notably, the phase III MIRASOL trial demonstrated improved survival outcomes with MIRV over standard chemotherapy, extending median overall survival (16.46 vs. 12.75 months; HR 0.67) and progression-free survival (5.62 vs. 3.98 months; HR 0.65), with an objective response rate (ORR) of 42.3% versus 15.9%. Furthermore, the single-arm phase II SORAYA trial reported an ORR of 32.4% in pretreated patients, including those with prior PARP inhibitor and bevacizumab exposure. Although the preceding FORWARD I trial missed its primary endpoint in the unselected population, its high-FR\u03b1 subgroup analysis revealed a clinical benefit that influenced subsequent biomarker-driven enrollment strategies. From a safety perspective, MIRV exhibited lower rates of severe neutropenia and anemia than chemotherapy, with toxicities primarily consisting of manageable, reversible ocular events. Ultimately, MIRV serves as a therapeutic option for platinum-resistant, FR\u03b1-positive ovarian cancer, offering survival advantages; however, rigorous biomarker-based screening remains necessary to optimize therapeutic outcomes.",

Oxidative stress and impaired neurotrophic signalling contribute to PD pathogenesis. Oleuropein (Ole), a phenolic compound found in olives and olive leaves, exhibits antioxidant and cytoprotective properties that may counteract neuronal injury. This study investigated the neuroprotective effects of Ole in differentiated dopaminergic neurons (dDCNs) derived from the human ReNcell VM model exposed to 6-hydroxydopamine (6-OHDA). Ole significantly attenuated 6-OHDA-induced cytotoxicity, restoring cell viability following post- and pre-treatment compared with toxin-treated cells. Tyrosine hydroxylase expression was preserved, indicating maintenance of the dopaminergic phenotype. Ole also reduced lipid peroxidation and restored total antioxidant capacity, supporting a role in redox homeostasis. Molecular docking suggested a stable interaction between Ole and the RET receptor tyrosine kinase, suggesting a potential involvement of RET-associated survival signalling pathways that requires further experimental validation. In addition, 6-OHDA altered extracellular vesicle (EV) release and EV-associated transcripts related to Wnt signalling (Wnt3a, Wnt5a, GSK3), while Ole partially restored EV release profiles and EV-associated Wnt signalling-related transcripts. Collectively, these findings indicate that Ole protects dDCNs from oxidative stress and highlight its potential as a neuroprotective agent against dopaminergic neuronal injury.",

This review systematically explores how the interplay between brain insulin resistance (BIR) and neuroinflammation contributes to the pathogenesis of DE. BIR refers to the diminished responsiveness of the CNS to insulin signaling, resulting in the suppression of the PI3K/Akt and MAPK pathways, impaired glucose metabolism, and dysfunction across multiple neural cell types-including neurons, astrocytes, microglia, brain endothelial cells, and oligodendrocytes. These disturbances manifest as impaired energy metabolism, compromised synaptic plasticity, disruption of the blood-brain barrier, and reduced myelination. Importantly, BIR and neuroinflammation form a vicious cycle within these cells, mutually exacerbating each other and jointly driving the pathological progression of DE. Finally, we have compiled a list of currently available drugs that can improve BIR and suppress neuroinflammation, along with the latest progress in clinical trials, to provide new insights for the future of precision treatment for DE.",

Currently, there is a notable absence of effective pharmacological agents to prevent or treat neuroinflammatory processes associated with AD. Heat shock protein 70 (HSP70) is pivotal in the progression of neuroinflammation. In this study, we explored the potential of maltol, a Maillard reaction product derived from red ginseng, as a therapeutic agent for neuroinflammation. Methods: In vitro, HMC3 microglial cell models were developed to examine the regulatory effects of gradient concentrations of maltol (12.5, 25, 50 \u03bcM) on the TLR4/MyD88/NF-\u03baB p65 signaling pathway, neuroinflammation, and pyroptosis. Analyses of the GEO database and Gene Set Enrichment Analysis (GSEA) were performed to identify the core targets of maltol, followed by HSP70 gene silencing experiments to validate the targeted regulatory mechanism. Results: Maltol significantly mitigated LPS-induced neuronal damage and cognitive deficits in mice. It effectively suppressed microglia-mediated neuroinflammation and pyroptosis, reversed oxidative stress-induced neuronal ferroptosis, and inhibited neuronal apoptosis. In vitro experiments demonstrated that maltol obstructed TLR4/MyD88 binding, thereby inhibiting NF-\u03baB p65-mediated neuroinflammation and pyroptosis, while also alleviating excessive ROS accumulation to enhance oxidative stress and ferroptosis. Bioinformatics analysis identified HSP70 as a crucial target for the anti-inflammatory and antioxidant effects of maltol. Subsequent gene silencing experiments confirmed that maltol exerted its inhibitory effects on LPS-induced neuroinflammation and pyroptosis in an HSP70-dependent manner. Conclusions: Maltol exhibits significant protective effects against Alzheimer's disease-related neuroinflammation, oxidative stress, pyroptosis, and ferroptosis through the targeting of HSP70. This study elucidates the molecular mechanisms by which maltol improves neuroinflammatory injury and provides a novel theoretical foundation and therapeutic strategy for the intervention of Alzheimer's disease neuroinflammation using traditional Chinese medicine.",

Purpose: This study aims to validate the hypothesis that Scu extract improves cerebral ischemia-reperfusion injury (CIRI) by inhibiting ferroptosis through the PI3K/AKT signaling pathway. Methods: This study employed middle cerebral artery occlusion (MCAO) in male Sprague-Dawley (SD) rats and oxygen-glucose deprivation/reoxygenation (OGD/R) models to evaluate the protective effects of Scu extract against CIRI. Multiple approaches were integrated to elucidate the underlying mechanisms. Furthermore, a range of experimental techniques, including neurological function assessment, TTC staining, histopathological analysis, biochemical assays, qPCR, transmission electron microscopy (TEM), reactive oxygen species (ROS) detection, Western blotting, and immunofluorescence, were used to comprehensively validate its neuroprotective effects. Results: Scu extract significantly improved neurological outcomes and attenuated brain injury in MCAO rats. Proteomic analysis revealed significant enrichment of ferroptosis-related pathways, which was supported by reduced mitochondrial damage, decreased iron accumulation, and restoration of the SLC7A11/GPX4 axis. Subsequently, UPLC/Q-TOF-MS analysis revealed that four major bioactive components were absorbed in MCAO rats. KEGG pathway analysis based on network pharmacology further indicated that the PI3K/AKT signaling pathway is a key regulatory target. Notably, pharmacological inhibition of PI3K with LY294002 markedly abolished the anti-ferroptotic effects of Scu extract, which was further confirmed in vitro. Conclusions: This study demonstrates that Scu extract confers neuroprotection against CIRI in MCAO rats potentially through inhibiting ferroptosis via activation of the PI3K/AKT pathway.",

Recent evidence suggests that vitamin D signaling contributes to the pathogenesis and progression of several neurodegenerative disorders. Vitamin D exerts neuroprotective effects through multiple mechanisms, including regulation of calcium homeostasis, modulation of immune responses, reduction in oxidative stress, stimulation of neurotrophic factors, and maintenance of blood-brain barrier (BBB) integrity. Vitamin D receptors and metabolizing enzymes are widely distributed across several brain regions, highlighting their direct involvement in neuronal function. This review summarizes the biosynthesis, metabolism, and signaling pathways of vitamin D. It explores its role in neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), stroke, and traumatic brain injury (TBI). Evidence from experimental and clinical studies indicates that vitamin D deficiency is associated with an increased risk and severity of these conditions, while supplementation may provide therapeutic benefits.",

Emerging evidence demonstrates that polyphenol-rich plant foods are potential complementary therapies for AD. In this study, we investigated crude polyphenol extracts (CPEs) and purified polyphenol extracts (PPEs) from three sorghum genotypes for their ability to inhibit A\u03b242-induced toxicity in MC-65 cells. Thioflavin T fluorescence, cell viability, mitochondrial function, oxidative stress assays, and Western blotting, along with RNA sequencing and computational analyses, were used to characterise both functional and transcriptomic responses of the cells to polyphenol treatments. CPEs and PPEs inhibited A\u03b242 aggregation by 67-76% and significantly reduced A\u03b2 oligomer species. The extracts increased cell viability against A\u03b2-induced toxicity by more than 70%, decreased intracellular oxidative stress, and enhanced mitochondrial activity by over 80%. Transcriptomic profiling revealed differential modulation of genes associated with ferroptosis and MAPK/NF- \u03baB signalling pathways, indicating regulation of inflammatory and oxidative-stress responses are mechanisms underlying the observed neuroprotection. This study demonstrates that polyphenol extracts from black and red sorghum genotypes exert strong multitarget neuroprotection against A\u03b242 toxicity in MC-65 cells. These findings support further evaluation of sorghum-derived polyphenols as complementary therapeutic candidates for AD, with in vivo studies required to establish efficacy and translational potential.",

Genistein, a soybean-derived isoflavone with antioxidant and neuroprotective potential, may counter heavy metal-induced neural injury; however, whether its efficacy is associated with redox-metabolic remodeling is unclear. Here, we evaluated genistein in lead-exposed C57BL/6J mice and lead-challenged HT22 hippocampal neurons. Genistein improved novel-arm exploration and spatial memory without altering locomotor or swimming performance, and attenuated neuronal disorganization and apoptosis in hippocampal CA1, CA3 and dentate gyrus regions. These protective effects were accompanied by reduced blood and hippocampal lead accumulation, restored glutathione redox balance, enhanced antioxidant capacity, preserved mitochondrial integrity, and suppressed Bax/Caspase-3-associated apoptotic signaling. Importantly, because genistein also reduced hippocampal lead accumulation, the in vivo neuroprotection may reflect both reduced target-tissue lead burden and improved glutathione-related redox homeostasis. Untargeted metabolomics identified 59 genistein-responsive metabolites enriched mainly in glutathione metabolism, oxidative phosphorylation, and ascorbate/aldarate metabolism, linking metabolic remodeling to behavioral recovery and reduced oxidative-apoptotic injury. In HT22 cells, blockade of glutathione synthesis by buthionine sulfoximine markedly weakened genistein-mediated cytoprotection, mitochondrial membrane potential recovery, and apoptosis inhibition. Collectively, genistein mitigates lead-induced hippocampal neurotoxicity and cognitive impairment by restoring glutathione-centered redox-mitochondrial homeostasis, supporting its further development as a mechanistically defined dietary candidate for environmental pollutant-associated neural injury.",

Growing evidence suggests that indole-derived compounds have significant neuroprotective potential due to their antioxidant, anti-inflammatory, and redox-modulating properties. This review summarizes the structural and biological significance of indole scaffolds, focusing on the mechanisms by which natural, endogenous, microbiota-derived, and synthetic indole compounds protect neuronal networks. Indole-3-carbinol, 3,3'-diindolylmethane, indole-3-propionic acid, and melatonin are major indole derivatives that control important neuroprotective pathways like Nrf2/ARE signaling, mitochondrial bioenergetics, neurotrophic factor expression, apoptotic regulation, and suppression of proinflammatory mediators. These compounds also maintain synaptic plasticity, reduce reactive oxygen species production, and improve neuronal survival in neurodegenerative disease models. Additionally, updated information from translational and clinical research indicates that indole-based compounds may have promising therapeutic applications; however, obstacles like low bioavailability, metabolic instability, and blood-brain barrier penetration continue to be major obstacles to clinical application. Development in nanoparticle delivery systems, microbiome-targeted interventions, and rational structural optimization may improve therapeutic efficacy and translational potential. Overall, indole-derived compounds are a versatile class of redox modulators with potential applications in the prevention and treatment of neurodegenerative diseases via integrated antioxidant and neuroprotective mechanisms.",

This review explores the intranasal (IN) route as a promising strategy for targeting both the anterior and posterior segments of the eye. The IN route leverages several distinct pathways: the nasolacrimal reflex for remote physiological stimulation; the \"neural bridge\" through the cribriform plate, allowing direct perineural and vascular transport via the olfactory and trigeminal nerves to bypass the blood-retinal barrier; and systemic absorption that avoids hepatic first-pass metabolism. Pre-clinical evidence indicates that IN administration of agents such as erythropoietin, nerve growth factor, and insulin achieves superior retinal concentrations compared to topical or systemic dosing, offering neuroprotection in models of retinal degeneration and glaucoma. Clinically, varenicline nasal spray is already FDA-approved for dry eye disease, while intranasal steroids demonstrate a favorable ocular safety profile without significantly increasing intraocular pressure. Although limited by mucociliary clearance and small delivery volumes, the IN route offers a painless, non-invasive alternative to intraocular injections, potentially enhancing patient compliance. Future advancements in mucoadhesive nanocarriers are essential to optimize drug residence time and realize the full potential of nose-to-eye delivery in chronic ophthalmic care.",

Methods: In this prospective, non-randomized comparative study, 65 eyes of 65 patients underwent combined cataract and micro-invasive glaucoma surgery with either iStent or Hydrus implantation. Intraocular pressure (IOP), number of glaucoma medications, best-corrected visual acuity (BCVA), surgical success, postoperative complications, and subsequent glaucoma procedures were analyzed over a 60-month follow-up. Results: At 60 months, outcome data were available for 47 eyes (72.3%), including 25 eyes in the iStent group and 22 eyes in the Hydrus group. Baseline characteristics did not differ significantly between groups. Mean IOP at 60 months was similar after iStent and Hydrus implantation (16.7 \u00b1 1.8 mmHg vs. 16.5 \u00b1 1.9 mmHg, respectively). The mean number of glaucoma medications decreased from 1.86 \u00b1 0.94 to 1.36 \u00b1 1.08 in the iStent group and from 1.60 \u00b1 0.72 to 0.36 \u00b1 0.49 in the Hydrus group, with significantly fewer medications required after Hydrus implantation at 60 months. Medication-free complete surgical success using the IOP \u2264 18 mmHg criterion was achieved in 20.0% of iStent-treated eyes and 63.6% of Hydrus-treated eyes. No eye underwent additional glaucoma surgery or selective laser trabeculoplasty during follow-up. Conclusions: In this prospective non-randomized comparative cohort, both procedures provided comparable long-term treated IOP control when combined with phacoemulsification. Hydrus implantation was associated with a greater medication-sparing effect and a higher proportion of medication-free complete surgical success at 5 years; however, these findings should be interpreted in the context of the non-randomized design and available-case follow-up.",

Methods: This retrospective cohort study included 187 eyes from patients aged \u226550 years that underwent cataract surgery alone or combined cataract-glaucoma surgery (goniotomy or Ahmed retrobulbar/intraconal tube) at a single center in Queens, New York. Preoperative and \u22653-month postoperative data included IOP, visual acuity (logMAR), medication burden, visual field mean deviation, and anterior segment biometry. Patients were stratified by surgical type, diagnosis, and glaucoma risk. Associations between LT and postoperative IOP reduction were analyzed. Results: Mean LT was 4.53 mm. Greater LT was associated with increased postoperative IOP reduction across all groups. Eyes with LT \u22654.5 mm showed greater IOP reduction compared to LT \u22644.2 mm (2.63 vs. 1.19 mmHg). Combined procedures yielded greater IOP reduction than cataract surgery alone, with the largest decrease in the Ahmed group (-4.56 mmHg). Cataract surgery alone produced smaller but significant reductions (-1.58 mmHg) and the greatest visual acuity improvement. Medication burden decreased substantially in the combined groups. Patients with angle-closure glaucoma had the highest LT. High-risk patients demonstrated greater IOP reduction than low-risk patients. Conclusions: Increased LT may serve as a predictive biomarker for postoperative IOP reduction. Incorporating LT and the Laroche Glaucoma Risk Calculator into preoperative planning may enhance surgical decision-making and outcomes, particularly in underserved populations.",

However, the relationships between comprehensive geriatric assessment (CGA) results and specific adherence-related problems remain poorly understood. This study investigated the associations between CGA results and glaucoma eye drop adherence-related problems using the newly developed Shimane University Glaucoma Eye Drop Adherence Questionnaire (SU-GAQ). Methods: This retrospective study included 187 consecutive glaucoma patients who underwent CGA and completed the SU-GAQ at Shimane University Hospital. The SU-GAQ consists of Knowledge (Q1-Q5) and Technique (Q6-Q15) domains. CGA included the Mini-Cog, G8, and Age-Adjusted Charlson Comorbidity Index (ACCI). Associations between questionnaire responses and CGA results were evaluated using Spearman's rank correlation and generalized regression analyses. Exploratory factor analysis (EFA) based on tetrachoric correlations was performed to evaluate the questionnaire structure. Results: Lower Mini-Cog scores were significantly associated with higher Knowledge-domain scores (\u03c1 = -0.27, p = 0.0002) and higher overall questionnaire scores (\u03c1 = -0.23, p = 0.002). In multivariate analysis, Mini-Cog remained independently associated with the Knowledge domain (estimate = -0.31, p < 0.0001) and total score (estimate = -0.44, p = 0.002). Higher ACCI scores were associated with higher Technique-domain scores (\u03c1 = 0.19, p = 0.009) and remained significant in multivariate analysis (estimate = 0.16, p = 0.02). G8 scores were not significantly associated with questionnaire outcomes. EFA identified a two-factor structure corresponding to the predefined Knowledge and Technique domains, accounting for 71.2% of the total variance. Conclusions: Lower cognitive function was primarily associated with knowledge-related barriers to glaucoma medication adherence, whereas greater comorbidity burden was associated with technical difficulties in eye drop instillation. The SU-GAQ demonstrated a clinically meaningful two-domain structure and may facilitate identification of specific adherence-related barriers in glaucoma patients.",
        "42452675": "ID: 42452675\nTitle: The Pathophysiological Association Between Obstructive Sleep Apnea and Glaucoma: A Current Update.\nAbstract: Glaucoma is a chronic, progressive optic neuropathy and the second leading cause of irreversible blindness worldwide. Although elevated intraocular pressure (IOP) remains the principal modifiable risk factor, it is neither necessary nor sufficient for disease development. The literature indicates that systemic conditions such as obstructive sleep apnea (OSA) may contribute to its pathogenesis. The pathophysiology of glaucoma is supported by several theories, primarily the mechanical and vascular theories. This review describes the pathophysiological links between OSA and glaucoma considering current theories. The principal connecting mechanism appears to be chronic intermittent hypoxia and reduced ocular perfusion pressure, which trigger optic nerve head hypoxia, oxidative stress, and biomechanical remodeling of the lamina cribrosa. These processes interact within a vicious cycle that progressively compromises the metabolic support of optic nerve axons. The mechanisms described are particularly relevant to normal-tension glaucoma, which may be associated with OSA. Retinal nerve fiber layer thinning appears among the earliest markers of optic nerve vulnerability, whereas IOP and visual field changes are more variable. These observations underscore the clinical relevance of the OSA-glaucoma relationship and support a multidisciplinary approach incorporating routine ophthalmic screening for subclinical optic nerve damage.",
        "42452694": "ID: 42452694\nTitle: Evolving Landscape of Regenerative Therapies: Cell-Based and Cell-Free Approaches for Chronic Low Back Pain.\nAbstract: Background: Chronic low back pain (CLBP) is the leading cause of years lived with disability globally, affecting over 600 million individuals. Intervertebral disc degeneration (IVDD) is a principal structural contributor, yet conventional treatments, including pharmacotherapy, physical therapy, and surgical intervention, do not reverse the underlying degenerative pathology. Regenerative medicine has introduced a spectrum of biological therapies for IVDD, including cell-based mesenchymal stromal cell (MSC) therapy, platelet-derived products such as platelet-rich plasma (PRP) and platelet lysate, extracellular vesicle-based approaches using MSC-derived extracellular vesicles (EVs), and secretome-based therapies using MSC-derived secretomes. However, these approaches have largely been studied in isolation, without a unified framework to compare their respective advantages and limitations in CLBP secondary to IVDD. Accordingly, this narrative review aims to provide an integrated and comparative evaluation of these regenerative strategies within a single translational and clinical context. Methods: For this narrative review, PubMed, Scopus, and Web of Science were searched from January 2000 to January 2026 using terms combining regenerative modalities with intervertebral disc degeneration, and chronic low back pain. Randomized controlled trials (RCTs), prospective cohort studies, systematic reviews, and preclinical studies with translational relevance were included. Results: Intradiscal MSC therapy has demonstrated safety across multiple phase I-III trials, but two recent landmark RCTs (RESPINE and the Mesoblast phase III trial) failed to meet primary efficacy endpoints, highlighting the gap between preclinical promise and clinical outcomes. PRP has the largest clinical evidence base, with level II evidence supporting short- to medium-term pain relief for discogenic pain, although standardization remains a critical barrier. Platelet lysate, MSC-derived EVs, and MSC-derived secretomes show compelling preclinical data, including extracellular matrix restoration, anti-inflammatory modulation, and attenuation of nucleus pulposus cell apoptosis, but remain at early translational stages for spinal applications, with no completed RCTs. The hostile disc microenvironment (avascular, hypoxic, acidic, and nutrient-poor) poses unique challenges for all regenerative modalities, differing fundamentally from other musculoskeletal applications. Conclusions: The studies included in this narrative review suggest that no single regenerative modality has yet shown consistent and unequivocal efficacy for CLBP secondary to IVDD across clinical trials. Cell-free approaches offer manufacturing, scalability, and safety advantages over cell-based therapies, but lack clinical validation. Future progress requires standardized preparation protocols, disc-specific delivery systems, patient phenotyping strategies, and rigorously designed comparative clinical trials. This narrative review provides a framework for researchers and clinicians to evaluate these therapies in context rather than isolation.",
        "42453098": "ID: 42453098\nTitle: Cutaneous laser treatment of port-wine stains and its impact on ocular manifestations in Sturge-Weber syndrome.\nAbstract: Sturge-Weber Syndrome (SWS) is a rare neurocutaneous disorder characterized by the presence of port-wine stains (PWS) and ophthalmologic complications, including glaucoma and choroidal hemangiomas. These manifestations result from somatic mutations in the GNAQ gene, leading to vascular malformations that affect both the skin and ocular tissues. This review aims to evaluate the impact of laser treatment for PWS on ocular manifestations in SWS, considering both clinical outcomes and underlying biological mechanisms. PWS are common in SWS patients and significantly impair quality of life (QoL) and necessitate effective treatment strategies. Pulsed dye laser (PDL) therapy, which targets the abnormal blood vessels within PWS, has been established as an effective method for reducing the size and appearance of these stains. Clinical studies suggest that PDL therapy not only improves dermatologic outcomes but may also have possible association with ocular vascular dynamics such as reducing intraocular pressure and ameliorating choroidal hemangiomas. The review evaluates data from various studies and highlights changes in intraocular pressure, the incidence of glaucoma, and modifications in choroidal hemangiomas following laser treatment. Mechanistic insights suggest that laser therapy may improve dermatologic and ocular symptoms by modulating sebaceous gland activity and enhancing the skin's barrier function, thereby indirectly affecting ocular health. Additionally, the review discusses the safety profiles of different laser systems, the importance of multidisciplinary care, and the need for standardized treatment protocols to minimize risks and optimize patient outcomes. Integrated dermatologic and ophthalmologic care remains crucial in improving the overall health and QoL for patients with SWS.",

A novel, polyherbal ethanol extract (PHE) formulation from Tinospora cordifolia, Commiphora wightii, Cinnamomum zeylanicum, and Paeonia officinalis was evaluated for antidiabetic and organ-protective effects at different levels for multi-targeting in a streptozotocin (STZ)-induced rat model. Male Wistar rats were made diabetic using intraperitoneal administration of streptozotocin (55\u00a0mg/kg) and randomly segregated into five groups: Normal, STZ-induced diabetic, STZ + PHE (200\u00a0mg/kg/day), Normal + PHE, and STZ + metformin (Met; 300\u00a0mg/kg/day). After 8 weeks of treatment, FBG, HbA1c, insulin, lipid profile, proinflammatory cytokines (TNF-\u03b1, IL-1\u03b2), oxidative stress biomarkers, and liver function markers were determined. Histological examination was performed on liver and pancreatic tissues with H&E staining, along with assessment of pancreatic insulin immunoreactivity. GC-MS analysis was conducted to characterize the phytochemical constituents of PHE. PHE treatment significantly reduced FBG by 33%, HbA1c by 15%, and restored serum insulin levels (+34%) versus untreated diabetics (p < 0.05). Dyslipidemia was corrected, with LDL-C reduced by 30% and HDL-C increased by 46%. Hepatic ALT and AST levels were also attenuated after PHE treatment. Oxidative stress was alleviated, and TNF-\u03b1 and IL-1\u03b2 levels in the liver and pancreas were markedly suppressed. Histology showed preserved hepatocyte integrity and islet morphology, and immunohistochemistry confirmed improved \u03b2-cell integrity and enhanced insulin immunoreactivity. The polyherbal preparation produced impressive control over glycemia, strong antioxidant and anti-inflammatory effects, and protection of liver and pancreatic architecture. These effects translate into its potential as a phytotherapeutic candidate for safely managing diabetes and its complications, warranting further molecular and clinical research.",

The study aimed to investigate the efficacy of Avastin in improving visual acuity (VA) and reducing central foveal (CFT) and parafoveal thicknesses (PFT) in participants with DR. A cross-sectional observational study was conducted at a tertiary hospital in the Gauteng Province (South Africa). A total of 55 participants were included in the study, with VA's that were less than 0.5 LogMAR units and CFT's greater than 300 microns (\u00b5m). Measurements of VA's, CFT (\u00b5m), and PFT (\u00b5m) were conducted at baseline, after three and six months of receiving Avastin treatment. Numerical data were collected and analysed using IBM SPSS Version 28, and non-parametric tests were used to compare the means of the variables. The mean VA improved from 1.00\u00b10.71 LogMAR at baseline to 0.66\u00b10.51 and 0.57\u00b10.48 LogMAR at 3 and 6 months, respectively (p <0.001).

At 6 months, the decrease in the NPFT was statistically significant (p <0.025) in improving VA. Early administration of Avastin treatment in diabetic patients is effective in reducing the mean CFT, NPFT, and improving the mean VA.",

A 67-year-old male with primary open-angle glaucoma developed endophthalmitis 2\u2009months after XEN45 implantation. Upon referral to our tertiary care center, he underwent urgent implant removal, penetrating keratoplasty with temporary keratoprosthesis, and pars plana vitrectomy with intravitreal antibiotics. Cultures grew Streptococcus gordonii. A second corneal transplant with fresh donor tissue was performed 4\u2009months later. Despite vision limited to light perception, the infection resolved and the eye was preserved. This is the first reported case of XEN45 Gel Stent-associated endophthalmitis which was successfully controlled with combined keratoplasty and vitrectomy. Our review of published cases identified 45 minimally invasive glaucoma surgery-related endophthalmitis cases, with XEN45 accounting for 58%. Potential risk factors included the XEN45 stent's susceptibility to exposure after conjunctival erosion, pool water exposure, and ab externo insertion during implantation.

This retrospective study included\u00a040 eyes of 31 patients\u00a0undergoing PreserFlo MicroShunt implantation performed by two experienced surgeons using a standard ab-externo technique with mitomycin C (0.04% for 3\u00a0minutes) and a structured postoperative corticosteroid tapering regimen. Outcomes assessed at 12 months included intraocular pressure (IOP), number of topical glaucoma medications, visual acuity, optic nerve and retinal nerve fibre layer parameters, visual field indices, complications, and surgical success.\u00a0Complete success\u00a0was defined as achieving target IOP without medications, while\u00a0qualified success\u00a0allowed adjunctive medications. Mean IOP was reduced from a preoperative median of 19.0 mmHg to 11.5 mmHg at 12 months\u00a0(p < 0.001). The median number of glaucoma medications decreased from 3.8 to 0.2 drops. At one-year,\u00a0complete surgical success was achieved in 82.5% of eyes, while\u00a0qualified success was 95.0%. Surgical failure occurred in\u00a05.0%\u00a0of eyes. Early postoperative hypotony (IOP \u22645 mmHg) occurred in\u00a017.5%, with persistent hypotony at one year in\u00a02.5%, none of which resulted in vision loss. No cases of sight-threatening complications such as endophthalmitis, corneal decompensation, or loss of light perception were observed. Structural and functional glaucoma parameters remained stable over the follow-up period. Postoperative interventions were required in a proportion of eyes during follow-up. PreserFlo MicroShunt implantation was associated with reductions in IOP and glaucoma medication burden at one year, with generally acceptable short-term safety outcomes. These findings support its role as an effective bleb-forming minimally invasive glaucoma surgery option for patients requiring lower target IOPs, including those with advanced glaucoma. However, the results should be interpreted in the context of the modest sample size, retrospective design, absence of a comparator group, and need for postoperative interventions. This study provides\u00a0the first Malaysian real-world data\u00a0on PreserFlo MicroShunt outcomes and adds to the growing regional evidence base for its use.",

From NCBI dbSNP database, we recently identified a previously uncharacterized single nucleotide variant (SNV) R881S in NBCe1, located in hydrophilic helix 4. R881S NBCe1-A showed intracellular retention in human embryonic kidney 293 cells and its plasma membrane expression was profoundly reduced in polarized Madin-Darby canine kidney cells. Unlike WT and R881C NBCe1-A (which causes pRTA), Western blot analysis demonstrated that the R881S NBCe1-A showed a single, low-molecular-weight signal at above 100kDa. Deglycosylation study showed that R881S NBCe1-A was scarcely deglycosylated by PNGase F. Coimmunoprecipitation study demonstrated that wild-type and R881S NBCe1-A did not form heterodimer. Moreover, functional analysis using Xenopus oocytes revealed that the R881S variant had markedly reduced transport activity compared with wild-type NBCe1-A. Thus, R881S NBCe1-A shows no detectable transport activity, likely due to defective trafficking and reduced glycosylation. In contrast to the R881C mutant, however, R881S NBCe1-A fails to form dimers with wild-type NBCe1-A, suggesting the absence of a dominant-negative effect and underscoring the need for functional characterization of reported genetic variants.",
        "42454630": "ID: 42454630\nTitle: Finite Element Modeling of Aqueous Outflow and Trabeculotomy in Glaucomatous Eyes With Resistive and Segmented Schlemm's Canal.\nAbstract: A novel open-angle glaucoma treatment procedure, femtosecond laser image-guided high-precision trabeculotomy (FLIGHT), non-invasively creates aqueous humor (AH) drainage channels from the anterior chamber (AC) to Schlemm's canal (SC) through the trabecular meshwork (TM). The channels decrease AH outflow resistance, thus decreasing intraocular pressure (IOP). The effect of the procedure greatly depends on the condition of the SC segment where the drainage channel ends. The purpose of this study was to develop a 3D finite element model (FEM) of the FLIGHT procedure in the case of resistive flow of the AH in the SC, including cases of segmental flow resulting from blocked or collapsed segments of the SC. We adopted the 3D FEM of the intact glaucomatous eye, including drainage system parameters, from our previous paper to simulate the FLIGHT treatment in eyes with resistive and segmental flow in the SC. The TM, SC and collector channels (CCs) were modeled as porous materials, with assigned permeability, to approximate the outflow resistance found in these tissues in-vivo. The permeability of segments of the SC was varied to model resistive and segmental flow within the SC. The FLIGHT treatment was simulated by removing block-like pieces of the TM to create channels that connected the AC to the SC. The size and locations of collapsed segments of SC in the FEM were varied to investigate their impact on IOP reduction following simulated FLIGHT. The FEM simulation results showed that the IOP reduction was maximized when FLIGHT drainage channels were in \"free flow\" segments of SC. Conversely, channels connecting the AC to blocked or collapsed regions of SC had a significantly diminished effect on IOP reduction. However, this was mitigated by replacing a single drainage channel with multiple channels that bypass the TM in different locations, including \"free flow\" segments. The condition of SC distal to the FLIGHT drainage channels has a significant influence on IOP reduction. The importance of multiple drainage channels targeting more segments of the SC is highlighted to mitigate the effect of collapsed segments of the SC.",
        "42454727": "ID: 42454727\nTitle: Beyond Acute Cytotoxicity: A Repair-Exhaustion Framework for Chronic Sublethal Benzalkonium Chloride Toxicity in Repeated Ophthalmic Exposure.\nAbstract: Benzalkonium chloride (BAK), a common preservative in multi-dose ophthalmic products, is often studied under acute high-dose exposure, which highlights overt damage to corneal epithelial cells. These studies tend to exaggerate the maximum cytotoxic effects and do not accurately reflect the gradual, cumulative damage seen during long-term use. By reviewing clinical, animal, and cellular data, we argue that repeated low-dose BAK exposure leads to barrier dysfunction, energy depletion, priming of inflammation, and impaired regeneration before significant cell death occurs. We suggest a repair-exhaustion model: minor injuries from repeated exposure are initially managed by membrane resealing and epithelial renewal, but over time, repair capacity becomes exhausted. This has two main implications: (i) long-term toxicity should be evaluated using functional measures such as barrier integrity, mitochondrial health, inflammation, and repair ability, and not cell viability alone; (ii) there may be a window during which reducing preservative levels or adding barrier-supporting and mitochondrial-protective agents can minimize cumulative damage. Instead of simply using or avoiding the preservative, this approach encourages formulation and clinical strategies that maintain antimicrobial effects while strengthening tissue resilience.",

Forty-three eyes were evaluated. Intraocular pressures at baseline and at the first, third, and sixth months after transscleral diode laser cyclophotocoagulation were compared. Ciliary body thickness, ciliary muscle thickness, ciliary process thickness, iris root thickness, and scleral thickness were assessed at baseline and at the third and sixth months post-treatment. Reductions in intraocular pressure were significant between baseline and the first month (p=0.018), third month (p<0.001), and sixth month (p<0.001) as well as between the first and third months (p=0.034) and the first and sixth months (p=0.036). Compared with baseline, intraocular pressure reduction rates at the first, third, and sixth months were 34.6%, 56.5%, and 55.3%, respectively, while success rates were 30.2%, 62.8%, and 55.8%, respectively. Decreases in ciliary body thickness, ciliary muscle thickness, and ciliary process thickness were significant between baseline and the third month (p<0.05) and between baseline and the sixth month (p<0.05), whereas changes between the third and sixth months were not significant (p>0.05). Iris root and scleral thicknesses did not change after treatment (p>0.05). At the third and sixth months, significant positive correlations were observed between changes in intraocular pressure and changes in ciliary body thickness and ciliary process thickness (p<0.05). To the best of our knowledge, this is one of the few studies comprehensively investigating structural changes after transscleral diode laser cyclophotocoagulation using ultrasound biomicroscopy. Moreover, the relationships between intraocular pressure changes and variations in the ciliary body, ciliary muscle, ciliary process, iris root, and scleral thicknesses were examined in detail. Single-session treatment did not affect iris root or scleral thickness but significantly reduced ciliary body, ciliary muscle, and ciliary process thicknesses. Greater reductions in ciliary body and ciliary process thickness may contribute to more pronounced intraocular pressure reduction.",

Patients who underwent gonioscopy-assisted transluminal trabeculotomy (at least 90\u00b0) for open-angle glaucoma and had a follow-up period of at least 12 months were included. Patients were grouped according to trabeculotomy degree (Group 1: 90\u00b0<\u03b8\u2264180\u00b0; Group 2: 180\u00b0<\u03b8<360\u00b0; Group 3: \u03b8=360\u00b0). Ophthalmic examination findings, intraocular pressure measurements, number of antiglaucoma medications, and complications were recorded. Surgical success was defined as intraocular pressure <15 mmHg with at least a 20% reduction; surgical failure was defined as failure to meet this criterion or the need for additional surgery. A total of 100 patients were included: 20 in Group 1, 24 in Group 2, and 56 in Group 3. Intraocular pressure levels differed significantly only in the first postoperative month (p=0.013). At 12 months, intraocular pressure levels, percentage reduction in intraocular pressure, and mean number of antiglaucoma medications did not differ significantly (p>0.05). No correlation was found between trabeculotomy degree and percentage intraocular pressure reduction (p=0.173). At 12 months, surgical success rates were similar (60.0%, 58.3%, and 64.3% for Groups 1, 2, and 3, respectively). Complication rates were also comparable among the groups. The degree of trabeculotomy did not affect surgical success over a 12-month follow-up period. Although early intraocular pressure reduction may differ with 360\u00b0 trabeculotomy, a complete 360\u00b0 incision may not be necessary to achieve optimal pressure reduction.",

Here, we adopted an integrated approach using behavioral, biochemical, histological, molecular, and in silico methods, exploring the neuroprotective efficacy of vitamin D against D-galactose-induced oxidative stress, neuroinflammation, and neurodegeneration. Chronic D-galactose administration (150\u00a0mg/kg, s.c) led to profound deficits in spatial learning, working memory, and recognition memory, besides increased oxidative stress, reduced antioxidant enzyme activity, suppression of Nrf2 and heme oxygenase-1 (HO-1) expression, and frank hippocampal neurodegeneration, as revealed by nissl staining. Vitamin D treatment (5\u00a0\u00b5g/kg i.p) significantly improved such deficits by restoring cognitive performance, reducing ROS and lipid peroxidation, enhancing endogenous antioxidant activities such as superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH) and glutathione peroxidase (GPx), and upregulating Nrf2 and HO-1 expression comparable to positive control, dimethyl fumarate (DMF). Co-administration of all-trans retinoic acid (ATRA), an antagonist for Nrf2, abrogated these protective effects, confirming the pathway specificity. Molecular docking studies have shown a strong binding affinity of Vitamin D to the regulatory domain of Nrf2, supporting a direct stabilizing interaction that may facilitate the activation of Nrf2. Nissl quantification has further demonstrated substantial preservation of neuronal integrity in hippocampal CA1, CA3, and DG regions following the treatment with vitamin D. Altogether, findings from this study show that vitamin D confers robust neuroprotection through Nrf2-dependent antioxidant mechanisms and mitigates aging-related neurodegeneration induced by D-galactose. The results highlighted vitamin D as a readily accessible therapeutic candidate for mitigating oxidative stress-driven cognitive decline.",

Nonpenetrating deep sclerectomy (NPDS) is theoretically safer than conventional penetrating surgery, yet comparative evidence lacks systematic synthesis. We systematically searched seven databases through December 2025. Eligible studies compared NPDS with conventional surgery in children with PCG aged under 4 years with\u2009\u2265\u20096\u00a0months follow-up. Two reviewers independently screened and extracted data; risk of bias was assessed with ROBINS-I and RoB 2.0. A random-effects meta-analysis [REML with Hartung-Knapp-Sidik-Jonkman (HKSJ) correction] was performed. Five studies [seven arms, 356 eyes; one randomized controlled trial (RCT), four observational] were included. Mean intraocular pressure (IOP) reduction was 10.34\u00a0mmHg (HKSJ 95% CI 7.54-13.14; 95% PI: 2.25-18.43\u00a0mmHg; I2\u2009=\u200997.2%, indicating substantial between-study variability driven primarily by differences in baseline IOP [\u03b2\u2009= +0.61\u00a0mmHg; P\u2009=\u20090.004], adjuvant use, and surgical technique; P\u2009<\u20090.001). Surgical success was achieved in 77.1% of eyes (95% CI 65.3-85.8%). Visual acuity improved by 0.329 LogMAR (approximately three Snellen lines; 95% CI 0.220-0.438; P\u2009=\u20090.001). The composite complication rate was 13.2% (95% CI 8.7-19.4%), with I2\u2009=\u20090% for hypotony, shallow anterior chamber, and hyphema. NPDS resulted in significantly fewer reinterventions (7.4% versus 14.1%; P\u2009=\u20090.046) and better corneal clarity preservation (92.4% versus 83.4%; P\u2009=\u20090.013) than non-NPDS procedures. Evidence comparing NPDS and conventional surgery in PCG remains limited. Surgery achieved a mean IOP reduction of 10.34\u00a0mmHg (HKSJ 95% CI 7.54-13.14), though estimates showed substantial heterogeneity (I2\u2009=\u200997.2%). While NPDS may be associated with lower reintervention rates and improved corneal clarity, no definitive differences in primary efficacy were observed. These findings require confirmation in well-designed prospective studies. PROSPERO registration: CRD420251121650. Primary congenital glaucoma damages the optic nerve from birth by obstructing aqueous outflow, and surgery, not medication, is the only way to prevent blindness. Standard operations (trabeculotomy, trabeculectomy) create a drainage channel by cutting through the full thickness of the ocular wall, whereas nonpenetrating deep sclerectomy (NPDS) dissects to the inner trabecular layer without breaching it, with the theoretical benefit of avoiding sudden postoperative hypotony and reducing lifetime infection risk. Whether this anatomical compromise preserves efficacy was the question we set out to answer. Searching seven databases through December 2025, we identified five comparative studies involving 356 eyes across four countries, all with at least 6 months\u2019 follow-up. Pooled analysis showed a mean intraocular pressure (IOP) reduction of 10.34\u00a0mmHg (95% CI 7.54\u201313.14), surgical success in 77% of eyes, and a mean visual acuity improvement of 0.33 LogMAR. The results are broadly comparable to conventional surgery, yet interstudy heterogeneity was extreme (I2\u2009=\u200997.2%), driven more by differences in baseline IOP, adjuvant mitomycin use, and surgeon experience than by anything intrinsic to the technique itself. The evidence has real limits: only one randomized trial was found, two studies carried serious risk of bias, and success was defined differently across centers. NPDS appears effective and safe. Whether it is better than conventional surgery, or in which patients it should be preferred, remains genuinely open. Answering that will require larger randomized trials with standardized outcome criteria.",

Survey of glaucoma patients to assess the level of awareness about the disease and its treatment. The questionnaire consisted of 11\u00a0specific questions that asked about education and satisfaction with treatment for glaucoma. It was developed by the Federal Association Glaucoma Self-help (Bundesverband Glaukom-Selbsthilfe e.\u202fV). in collaboration with the Glaucoma Section of the German Society of Ophthalmology (DOG) and made available to members of the association as well via the website and patient forums and in waiting rooms. A total of 334 glaucoma patients participated in the survey between July 2024 and June 2025. Of the respondents 15.5% stated that they were very well informed, while 40.1% reported they had been inadequately informed. There was a\u00a0lack of information on treatment options and side effects as well as on the prescribed eye drops. Patients therefore sought alternative sources of information (e.g., the internet). Results were also mixed when it came to information about treatment use and side effects and 89.5% said they knew how to use their treatment. Approximately 50% were able to discuss changes to their treatment or information about alternative treatments with their doctor. The findings from this survey should be used to develop more targeted patient education strategies in the future. Patient-centered understandable and continuous education should be a\u00a0central component of treatment. This would contribute to improved adherence and thus also to the quality of life of those affected. HINTERGRUND: Das Glaukom ist eine der h\u00e4ufigsten Erblindungsursachen weltweit, so auch in Deutschland. Dennoch ist unklar, ob alle Betroffenen ausreichend \u00fcber ihre Erkrankung sowie m\u00f6gliche Therapien und deren Nebenwirkungen informiert sind. Umfrage unter GlaukompatientInnen, um den Stand der Aufkl\u00e4rung \u00fcber die Erkrankung und m\u00f6gliche Therapien zu erfassen. Der Fragenbogen bestand aus 11\u00a0Fragen zur Aufkl\u00e4rung und Therapiezufriedenheit bez\u00fcglich des Glaukoms. Er wurde vom Bundesverband Glaukom-Selbsthilfe e.\u202fV. in Zusammenarbeit mit der Sektion Glaukom der Deutschen Ophthalmologischen Gesellschaft (DOG) entwickelt. Der Fragebogen wurde den Mitgliedern des Bundesverbandes sowie \u00fcber die Homepage und Patientenforen zug\u00e4nglich gemacht und in Wartezimmern ausgelegt. Es nahmen 334 GlaukompatientInnen von Juli 2024 bis Juni 2025 an der Umfrage teil; 15,5\u202f% der Befragten gaben an sehr gut aufgekl\u00e4rt zu sein, 40,1\u202f% gaben an, dass sie unzureichend aufgekl\u00e4rt wurden. Es fehlten Informationen zu Therapieoptionen und Nebenwirkungen sowie zu den verschriebenen Tropfen. Daher suchten PatientInnen nach alternativen Informationsquellen (z.\u202fB. Internet). Auch bei der Aufkl\u00e4rung \u00fcber die Therapieanwendung und Nebenwirkungen zeigten sich heterogene Ergebnisse; 89,5\u202f% gaben an zu wissen, wie sie ihre Therapie anwenden m\u00fcssen. \u00c4nderung der Therapie oder Informationen zu alternativen Therapien konnten ca.\u00a050\u202f% der Teilnehmenden mit ihrem Arzt besprechen. Durch die Erkenntnisse aus dieser Umfrage sollen zuk\u00fcnftig gezieltere Aufkl\u00e4rungsstrategien entwickelt werden. Eine patientenzentrierte, verst\u00e4ndliche sowie kontinuierliche Aufkl\u00e4rung sollte ein zentraler Bestandteil der Therapie sein. Dies w\u00fcrde zu einer Verbesserung der Adh\u00e4renz und somit auch der Lebensqualit\u00e4t der Betroffenen beitragen.",

This review provides a mechanistic overview of medicinal plants and probiotics in modulating key pathological processes underlying disorders such as Alzheimer's disease, epilepsy, autism spectrum disorder, and major depressive disorder. A systematic literature search was conducted across PubMed, Scopus, and Web of Science databases to identify relevant studies examining the neuroprotective, metabolic, and anti-inflammatory effects of plant-derived compounds, probiotics, and SGLT2 inhibitors. The findings highlight shared mechanisms, including attenuation of oxidative stress, suppression of neuroinflammation, modulation of mitochondrial function, and regulation of the gut-brain axis. Bioactive compounds such as polyphenols, flavonoids, alkaloids, and terpenoids demonstrate significant potential in improving neuronal survival and synaptic plasticity. Probiotics further contribute through microbiota-mediated regulation of neurotransmitters and immune responses. SGLT2 inhibitors are discussed as a comparative pharmacological model exhibiting overlapping mechanisms. Collectively, these integrative approaches provide a mechanistic framework for understanding how plant-derived compounds, probiotics, and metabolically active pharmacological models may influence shared pathways involved in neurological and psychiatric disorders. However, most proposed neuroprotective and synergistic effects require further validation through standardized formulations, well-designed clinical trials, and careful safety assessment before they can be translated into routine clinical practice.",

In primary open-angle glaucoma (POAG), pathological stimuli induce oxidative damage and promote excessive extracellular matrix (ECM) deposition in HTMCs, thereby hindering aqueous humor outflow. Salidroside (Sal), a compound with diverse pharmacological activities, has been reported to inhibit oxidative stress and reduce ECM accumulation. This study aimed to investigate whether Sal exerts its antioxidant effects by regulating matrix metalloproteinase 3 (MMP3) expression via the TNF signaling pathway. Potential targets of salidroside and glaucoma were predicted using SwissTargetPrediction and GeneCards online databases, and overlapping targets were identified. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed on these intersecting targets. Meanwhile, the glaucoma GEO dataset (GSE27276) was downloaded for differential gene expression analysis, and the results were further compared with the intersecting targets to identify key genes. An oxidative damage model of HTMCs was established using hydrogen peroxide (H\u2082O\u2082) induction. Cell viability was assessed using the MTT assay to determine the appropriate H\u2082O\u2082 concentration for modeling, as well as the safe dosage and treatment duration of Sal. Oxidative stress markers were measured as follows: superoxide dismutase (SOD) and malondialdehyde (MDA) levels were determined by enzyme-linked immunosorbent assay (ELISA), while reactive oxygen species (ROS) levels were assessed using DCFH-DA staining. Furthermore, the expression of ECM proteins such as collagen type I (COL-I), fibronectin (FN), and laminin (LN), as well as MMP3 and TNF signaling pathway-related proteins, was detected by Western blot and immunofluorescence (IF). Rescue experiments were performed using the TNF inhibitor R7050 and the broad-spectrum MMP inhibitor GM6001. In addition, a rat glaucoma model was established by injecting microbeads into the anterior chamber of SD rats. Intraocular pressure changes were monitored using a TonoLab tonometer. Retinal tissue morphology was observed by hematoxylin-eosin (H&E) staining. Retinal ganglion cell apoptosis was detected by TUNEL assay. The expression of oxidative stress markers and ECM-related proteins in the retina and serum was measured by Western blot and ELISA. A total of 68 intersecting targets were identified from the database analyses. Enrichment analysis indicated that these targets were primarily involved in biological processes such as oxidative stress and ECM regulation, as well as the TNF signaling pathway. Experimental results further demonstrated that Sal significantly increased the viability of H\u2082O\u2082-damaged HTMCs and effectively inhibited intracellular oxidative stress and ECM protein expression. Moreover, the TNF signaling pathway inhibitor R7050 enhanced the inhibitory effects of Sal on oxidative stress and ECM deposition in HTMCs. Screening of the GEO database identified MMP3 as a key gene. Western blot results showed that Sal upregulated MMP3 expression in H\u2082O\u2082-treated HTMCs. Furthermore, the MMP3 inhibitor GM6001 reversed the protective effects of Sal against oxidative stress and ECM deposition. Interestingly, in the presence of Sal, co-treatment with R7050 and GM6001 revealed that GM6001 reversed the effects of R7050 on oxidative stress and ECM, suggesting that Sal may act through the TNF/MMP3 axis. In vivo experiments further confirmed that Sal effectively reduced IOP in glaucomatous rats, alleviated retinal pathology, and significantly decreased oxidative stress levels and ECM deposition. Sal, both in vitro and in vivo, promotes MMP3 expression by inhibiting the activation of the TNF signaling pathway, thereby suppressing ECM deposition and mitigating oxidative damage in trabecular meshwork cells.",

We conducted an integrated epidemiological and experimental study combining a time-stratified case-crossover analysis of 4090 glaucoma patients in Shanghai with multivariable linear regression and mechanistic experiments. Extreme cold exposure was associated with increased glaucoma outpatient visits, and lower ambient temperature was associated with higher IOP across multiple lag days after adjustment for demographic, meteorological, and air pollution factors. In vivo, chronic cold exposure (4 \u00b0C, 22\u202fh/day, 4 weeks) was associated with sustained IOP elevation and anterior segment changes, accompanied by increased extracellular matrix (ECM) deposition, enhanced trabecular meshwork contractility, and elevated serum glucocorticoid and norepinephrine levels. In vitro, dexamethasone increased \u03b1-smooth muscle actin (\u03b1SMA) and collagen type I alpha 1 chain (COL1A1), while norepinephrine increased myosin regulatory light chain 2 (MLC2) phosphorylation. Transcriptomic analysis identified 5168 differentially expressed genes enriched in ECM organization, TGF-\u03b2 signaling, calcium signaling, and cGMP-PKG pathways. In conclusion, extreme cold exposure was associated with glaucoma-related outcomes and IOP elevation, and integrated evidence suggests that cold-related neuroendocrine activation may contribute to extracellular matrix remodeling and trabecular meshwork dysfunction, potentially affecting aqueous humor outflow and IOP regulation.",

G protein-coupled receptor 75 (GPR75), an orphan receptor, is a novel regulator of metabolic diseases. However, the role and mechanisms of GPR75 underlying diabetic RGCs mitochondrial dysfunction have not been reported. To investigate the function of GPR75, we knockdown the receptor in streptozotocin (STZ) mice and high glucose (HG)-treated primary RGCs. Our investigations revealed an upregulation of GPR75 in DR. Furthermore, we demonstrated that GPR75 knockdown could mitigate the progression of DR, with its protective effects associated with the inhibition of mitochondrial dysfunction in RGCs. Adenosine-5'-monophosphate (AMP)-activated protein kinase (AMPK), a regulator of mitochondrial function and a cellular energy sensor, was identified as a novel target of GPR75. Immunofluorescence and co-immunoprecipitation (CO-IP) analyses confirmed the co-localization and interaction between GPR75 and AMPK in RGCs. Mechanistically, the upregulation of GPR75 inhibits AMPK-mediated mitochondrial homeostasis, resulting in impaired mitochondrial dynamics, disrupted energy metabolism, and elevated reactive oxygen species (ROS), which ultimately trigger pyroptosis and apoptosis in RGCs. Notably, the AMPK-activator AICAR mitigates GPR75-induced mitochondrial dysfunction, pyroptosis, and apoptosis. In summary, our findings suggest that the targeted inhibition of GPR75 may represent a promising therapeutic strategy for DR.",
        "42456876": "ID: 42456876\nTitle: SPG302 Mitigates Diabetic Retinal Neuropathy and Inner Retinal Damage in a Genetic Mouse Model of Diabetes.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss stemming from vascular and neurodegenerative sequelae of impaired glucose metabolism. Diabetic retinal neuropathy (DRN), an early feature of DR that can precede the microvasculopathy, is characterized by inner retinal degeneration with loss of ganglion cells (GCs) and impaired GC function, decreased inner retina synaptic markers, and increased reactive gliosis and cell death. Loss of glutamatergic synapses in the retina precedes, and may contribute to, overt neuron loss in DR, thus offering a potential new point for therapeutic intervention. SPG302, a novel pegylated benzothiazole derivative, promotes glutamatergic synaptogenesis and protects the inner retina in a mouse model of glaucoma, another leading cause of blindness associated with early synapse loss in the retina. To evaluate potential protective effects of SPG302 in DR, db/db mice (a diabetic mouse model with an inactivation mutation in the leptin receptor) were treated with intraperitoneal SPG302 or vehicle for 8 weeks (16-24 weeks of age). Db/+ mice served as an additional control. Db/db mice demonstrated weight gain, hyperglycemia, insulin intolerance, and glucose intolerance, while db/+ mice did not. SPG302 treatment did not change these metabolic parameters. Following treatment, GC function was assessed using electroretinography (ERG). Mice were then euthanized for quantification of retinal GCs, synaptic markers, glial markers, and markers of cell death using immunofluorescence staining and Western blot methods. Db/db mice demonstrated significant loss of GC ERG signal and GC cell number, decreased PSD95 and synaptophysin expression indicative of synapse loss, as well as increased reactive gliosis and expression of cell death markers such as pBAD and BAX. SPG302 treatment effectively preserved retinal integrity by reversing these changes. Thus, SPG302 has therapeutic potential for protecting the inner retina and mitigating DRN in diabetes.",

Cross-sectional study SUBJECTS: All residents of Malm\u00f6, Sweden, aged 77-89 years were eligible for participation, except individuals with a prior glaucoma diagnosis at Sk\u00e5ne University Hospital. A total of 1957 individuals were invited, of whom 602 (30.8%) attended the screening. The screening procedure included intraocular pressure measurement using an Icare tonometer, visual field screening using the Frequency Doubling Technology (FDT) perimeter, and fundus photography. Subjects with positive screening results were offered a post-screening visit with a full ophthalmological examination, including threshold perimetry using the SITA Standard 24-2 program of the Humphrey Field Analyzer. The severity of disease was evaluated based on the perimetric mean deviation (MD) index. Prevalence of previously undetected open-angle glaucoma in individuals 77-89 years old (%) and the magnitude of visual field defects expressed as proportions (%) of patients in 5 different disease severity stages. The prevalence of previously undetected open-angle glaucoma was 5.98% (95% CI: 4.2%-8.2%), n= 35 patients. The condition was unilateral in 74% of patients. The severity of disease was early in 66% and moderate in 20%, while 14% of patients had advanced or severe disease. No patient had developed end-stage disease. The median intraocular pressure in glaucoma patients was 16 mmHg (IQR: 14-19 mmHg). The prevalence of previously undetected open-angle glaucoma was high in this age category, 5.98%, but most patients had early or moderate disease, and no patient had end-stage disease.",

In our preclinical studies, we demonstrated that a single Cerium-Oxide Nanoparticles (CeO2-NPs) intravitreal injection in a light-induced degeneration model, was able to counteract the retinal degeneration. Our aim was to investigate whether neuroprotection activity could be correlated with mitochondrial morpho-functional preservation. Bulk transcriptomic profiling of whole retinal tissue revealed that light-induced retinal injury was associated with suppression of mitochondrial-related gene networks, including components of the electron transport chain and regulators of mitochondrial dynamics, whereas CeO2-NPs treatment restored the expression of antioxidant and mitochondrial biogenesis-related genes. Ultrastructural analysis by electron microscopy showed preservation of Retinal Pigmented Epithelial mitochondria's morphology and by high-resolution crystallographic analysis confirmed the intracellular localization of CeO2-NPs in proximity to mitochondria. Furthermore, Western blot analysis demonstrated that CeO2-NPs maintained mitophagy markers at basal levels, preventing excessive activation of mitochondrial quality-control pathways. Together, these findings support mitochondrial preservation as a key mechanism underlying nanoceria-mediated retinal neuroprotection and highlight CeO2-NPs as promising candidates for maintaining retinal homeostasis in AMD.",

A systematic review was conducted using MEDLINE, Embase, Cochrane CENTRAL, and Web of Science from inception to March 2026. Eligible studies included adult glaucoma patients assessed with validated cognitive tools. Meta-analysis was performed for the Mini-Mental State Examination (MMSE), with pooled mean differences (MD) calculated using random-effects models. Indirect subgroup comparisons were performed by glaucoma subtype, geography, and age. Narrative synthesis was performed for MoCA and cognitive domain-specific assessments. Twenty-four studies (n\u202f=\u202f16 569) were included. MMSE meta-analysis suggested lower MMSE scores among glaucoma patients compared with controls (MD: -2.85; 95% CI: -3.36 to -2.34; p < .001), although substantial heterogeneity was present (I\u00b2\u202f=\u202f94.5%). Exploratory study stratification suggested greater MMSE reductions in developing countries (MD: -3.79; p < .001) than in developed countries (MD: -0.74; p > .05). Despite lower MMSE performance, scores remained above commonly used thresholds for CI. Narrative synthesis found that MoCA-based studies demonstrated inconsistent findings without a clear difference between glaucoma and comparator groups. Among domain-specific areas, deficits in verbal fluency, visuospatial skills, and memory were suggested. Interpretation of these findings was limited by the visual dependence of cognitive assessments, raising the possibility that visual impairment may reduce scores. Current evidence suggests a hypothesis-generating association that glaucoma may reduce performance on cognitive assessments. However, interpretation is limited by substantial heterogeneity and the visual dependence of cognitive assessments, highlighting the need for standardized, longitudinal studies to better define the scope and mechanisms of this relationship.",

Steroid-induced glaucoma and ocular hypertension often occur in medically complex eyes that may require continued corticosteroid therapy. Selective laser trabeculoplasty may provide intraocular pressure control while reducing dependence on topical glaucoma medications. This systematic review was registered with PROSPERO (CRD420251274498) and conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (or PRISMA) guidelines. Ovid MEDLINE, Embase, and the Cochrane Library were searched from inception to December 28, 2025. Eligible studies included patients with steroid-induced glaucoma or ocular hypertension treated with selective laser trabeculoplasty and reporting intraocular pressure outcomes. Two reviewers independently performed screening, full-text review, data extraction, and Risk Of Bias In Non-randomized Studies of Interventions-I (or ROBINS-I) risk-of-bias assessment. Because of heterogeneity in design, follow-up, and outcome reporting, results were synthesized descriptively. Nine studies comprising 162 eyes were included. Most were retrospective, with sample sizes ranging from 4 to 35 eyes and follow-up from 1 to 24 months. Baseline intraocular pressure ranged from 21.7 \u00b1 0.9 to 38.4 \u00b1 7.3 mm Hg, and final intraocular pressure ranged from 13.3 to 16.1 \u00b1 3.4 mm Hg. Reported intraocular pressure reduction ranged from 27.7% to 59.1%, with sustained effects beyond 12 months in several studies. Seven studies reported a reduced glaucoma medication burden after treatment. No major sight-threatening adverse events were identified. Risk of bias was moderate to serious in most studies. Selective laser trabeculoplasty appears to be a promising and generally safe option for steroid-induced glaucoma and ocular hypertension, but higher-quality prospective comparative studies are needed.",

Socioeconomic status (SES) may influence hypertension management; however, evidence on its associations with pharmacotherapy, lifestyle modification, and self-management education remains limited. In this study, the association between SES and hypertension-related outcomes in the Republic of Korea was investigated. In this nationwide cross-sectional study, data from the 2023 Korea Community Health Survey were analyzed, comprising 231,584 and 228,608 adults for educational attainment and household income analyses, respectively. Hypertension-related outcomes included diagnosed hypertension, pharmacotherapy, lifestyle modification, and self-management education. Crude and age- and sex-adjusted rates were calculated, followed by multivariable logistic regression analyses, adjusting for potential confounders. Overall, the prevalence of diagnosed hypertension was 31.3%. Among participants with hypertension, the rates of pharmacotherapy, lifestyle modification, and self-management education were 95.9%, 23.8%, and 15.5%, respectively. The multivariable analyses showed a dose-response relationship between SES and outcomes: participants with primary school education or less had higher odds of diagnosed hypertension (odds ratio, 1.79; 95% confidence interval, 1.71-1.88) and pharmacotherapy use (2.04; 1.67-2.50) but lower odds of lifestyle modification engagement (0.47; 0.43-0.50) and receiving self-management education (0.34; 0.31-0.38) compared to those with college degree or higher. Notably, these socioeconomic gradients remained robustly consistent across all strata, while significantly steeper gradients were observed among females and younger adults (<\u200965\u00a0years). Analyses by household income showed similar patterns of associations, although with slightly weaker magnitudes. Lower SES was associated with a higher prevalence of diagnosed hypertension and pharmacotherapy use but lower participation in lifestyle modifications and self-management education. Strengthening tailored self-management education and lifestyle modification support for socioeconomically disadvantaged groups may be an important strategy to reduce hypertension-related disparities.",

Stx4 is predominantly localized at the postsynaptic membrane of neurons and in glial cells, where it is essential for synaptic plasticity and the maintenance of neuronal homeostasis. Stx4 facilitates the activity-dependent exocytosis of glutamatergic receptors, thereby governing the balance between Long-Term Potentiation (LTP) and Long-Term Depression (LTD). Emerging evidence suggests that dysregulation of Stx4 is intricately linked to the pathogenesis of neurodegenerative diseases. In Alzheimer's disease, Stx4 is involved in synaptic dysfunction and cognitive impairment through its interactions with amyloid-\u03b2 (A\u03b2) and tau pathologies, affecting receptor recruitment at dendritic spines. In Parkinson's Disease (PD), Stx4 contributes to \u03b1-synuclein proteostasis, dopaminergic signaling, neuroinflammation, and the maintenance of blood-brain barrier integrity. While its presence in cerebrospinal fluid highlights its potential as a candidate biomarker for these diseases, further validation is required to establish clinical utility. This review summarizes current mechanistic insights into Stx4's multifaceted roles in the neurodegenerative disorders and explores the therapeutic prospects of targeting Stx4-mediated pathways due to its translational potential.",
        "42459363": "ID: 42459363\nTitle: Inhibiting the uPAR/FPR1 interactions reduces blood-retinal barrier breakdown and improves retinal function in a rat model of diabetes.\nAbstract: Diabetic retinopathy (DR) is a leading cause of blindness characterized by early neurovascular damage driven by hyperglycemia-induced mechanisms, including inflammation. The system composed of the urokinase-type plasminogen activator (uPA) and its receptor (uPAR) has previously emerged as a potential regulator of the pro-inflammatory events in DR, possibly through the interaction of uPAR with its lateral partners, such as formyl peptide receptors (FPRs). This study explored whether the inhibition of uPAR/FPR1 crosstalk may reduce early neurovascular alterations in DR by targeting inflammation. To this aim, the new FPR1 antagonist N-19004 was tested in a rat model of streptozotocin-induced diabetes. N-19004 was administered subcutaneously for 7\u202fdays at 1\u202fmonth from diabetes onset. Immunofluorescence, RT-qPCR, Western blot and Evans blue perfusion were performed to evaluate the effects of N-19004 on inflammation, reactive gliosis, blood-retinal barrier (BRB) integrity and apoptosis. In addition, electroretinogram (ERG) was used to assess N-19004 efficacy on retinal function. N-19004 inhibited the activation of inflammation-related transcription factors, including nuclear factor kappa-light-chain-enhancer of activated B cells and signal transducer and activator of transcription 3, leading to reduced interleukin-1\u03b2 and tumor necrosis factor-\u03b1 expression. The attenuation of inflammatory processes resulted in reduced glial activation, as indicated by lower glial fibrillary acidic protein expression and M\u00fcller cell gliosis. The anti-inflammatory activity of N-19004 was accompanied by decreased BRB breakdown, as demonstrated by N-19004-mediated reduction of vascular endothelial growth factor, increased levels of tight junction components and diminished vessel leakage. The amelioration of BRB integrity was associated with reduced activation of caspase 3 and partial preservation of scotopic ERG a- and b-wave amplitudes, thereby improving retinal viability and function in N-19004-treated STZ rats. These results support the possible involvement of uPAR/FPR1 interactions in the regulation of DR-related inflammation and suggest a novel therapeutic target for the management of the early phases of disease.",

The endocannabinoid system comprises endogenous ligands, termed endocannabinoids, and two principal receptors, cannabinoid receptor type 1 and type 2 (CB1R and CB2R). While CB1R is predominantly associated with the central nervous system and mediates the psychotropic effects of cannabis-derived compounds, CB2R was initially considered mainly peripheral. However, growing evidence over the last decades has highlighted a pivotal role for CB2R in central nervous system homeostasis and pathology. Importantly, the lack of psychotropic effects associated with CB2R signaling has positioned this receptor as a promising therapeutic target for several brain-related disorders, including neuroinflammatory, neurodegenerative, neuropsychiatric, and neurovascular conditions. Here, we provide a structured review of experimental studies published over the last 3 years investigating CB2R modulation in the central nervous system, with a particular focus on disease mechanisms and emerging therapeutic strategies.",
        "42460019": "ID: 42460019\nTitle: The influence of magnesium ions on the electrophysiological, analgesic, and BDNF-induced neuromodulation of morphine effects in diabetic rats.\nAbstract: Neuropathic pain is difficult to treat due to the involvement of multiple signaling pathways, including increased expression of sodium channels, decreased expression of potassium channels, heightened neuronal excitability from the activation of N-methyl-D-aspartate receptors (NMDARs), nerve damage leading to changes in neurotrophic factor levels, and reduced opioid efficacy. As a result, the treatment of neuropathic pain often requires a multifaceted approach. It has been shown that magnesium ions (Mg2+), which act as physiological antagonists of NMDARs, can augment opioid analgesia in chronic pain. The aim of this study was to assess the influence of Mg2+ on the electrophysiological, analgesic, and brain-derived neurotrophic factor (BDNF)-induced neuromodulation of the morphine profile in diabetic rats. Diabetes in male Wistar rats was induced by a single intramuscular injection of streptozotocin (STZ). The Plantar Test was used to assess the effect of Mg2+ and morphine co-treatment on STZ-induced hyperalgesia, expressed as increased warm sensitivity of the experimental rat hind paw. Ex vivo whole-cell recordings from ventrolateral periaqueductal gray (vlPAG) neurons were conducted to evaluate the frequency of action potentials evoked by incremental depolarizing current steps (current-clamp, 1-s steps). To assess glutamatergic signaling, neurons were voltage-clamped to measure NBQX-sensitive current at -70\u00a0mV and NMDA-evoked currents during depolarization in the presence of NMDA/glycine. Changes in BDNF concentrations in PAG structures were measured using an enzyme-linked immunosorbent assay. The results of our study suggest that although magnesium sulfate shows limited analgesic properties when administered alone, it can significantly enhance opioid efficacy when used as an adjunct. Moreover, the co-administration of morphine with magnesium sulfate resulted in a greater reduction in NMDA-evoked currents in diabetic rats compared to either agent alone. Overall, our findings support the concurrent use of Mg2+ and morphine in the treatment of neuropathic pain as a mechanism-informed adjunct strategy.",

A 29-year-old man with PIS and medically refractory chronic angle-closure glaucoma underwent an uneventful left-eye CLE, goniosynechiolysis, implantation of a toric extended depth-of-focus (EDOF) IOL, and insertion of three iStent infinite\u00ae\u00a0(Glaukos Corporation, Aliso Viejo, CA, USA) devices. Five weeks postoperatively, he presented with blurred vision, asthenopia, and binocular diplopia associated with a sudden -2.50 D myopic surprise. Dynamic slit-lamp examination revealed localized posterior synechiae extending from 1 to 5 o'clock. These adhesions exerted asymmetrical traction on the capsular bag, resulting in anterior displacement and temporal tilt of the IOL complex without pupillary block. The patient subsequently underwent targeted synechiolysis under local anesthesia. Postoperative biometry demonstrated an increase in anterior chamber depth (ACD) from 2.90 mm to 3.02 mm, confirming posterior repositioning of the IOL. Restoration of the effective lens position (ELP) reversed the myopic shift and resolved the patient's symptoms. This case highlights localized posterior synechiae as a rare but reversible cause of postoperative refractive surprise and underscores the importance of meticulous dynamic slit-lamp evaluation and ACD monitoring in patients with complex anterior segment conditions presenting with unexpected refractive outcomes. Timely synechiolysis may serve as a definitive and restorative intervention.",

While diagnostic tools are based on Caucasian cohorts, Whole Exome Sequencing (WES) studies are needed to identify new genes in non-Caucasians, as up to 77% of patients do not harbor variants of significance in MODY-known genes. No WES studies have addressed the genomic landscape of MODY beyond its canonical genes in Latino populations. We aimed to characterize the genomic landscape of MODY through WES in a Mexican cohort, comparing cases with type 2 diabetes mellitus (T2DM) patients and healthy controls (HC). WES was performed in 17 patients with MODY, 17 with T2DM and 17 HC. We compared the single nucleotide variant landscape across groups in MODY-known genes and searched for genetic variants with differential enrichment across groups. MODY genes used for routine diagnosis showed low discrimination utility, as patients with MODY, T2DM and HC harbored genetic variants in MODY-known genes at similar frequencies in most cases. We found 14 genes with variants capable of distinguishing MODY from T2DM and HC. Variants in genes such as MAP2K3, SYT15, KCNJ12, PEX5, and TPTE were found in 75-100% of MODY cases while absent in T2DM and HC. Enrichment analysis revealed involvement in synaptic vesicle trafficking, insulin/IGF pathway-mitogen activated protein kinase kinase/MAPK, and insulin/IGF pathway-protein kinase B/AKT signaling. MODY presents a complex genetic architecture in the Mexican population. Besides improving our understanding of glycemic regulation pathways, identified genes may serve as diagnostic biomarkers.",

Although DR has traditionally been classified as a microvascular complication, it is now increasingly recognized as a neurovascular degenerative disorder involving coordinated injury to neuronal, glial, vascular, and extracellular matrix components of the retinal neurovascular unit (NVU). The NVU provides the structural and functional basis for coupling neuronal activity to local blood flow and for maintaining retinal immune and barrier homeostasis. In diabetes, chronic hyperglycemia, oxidative stress, inflammation, metabolic dysregulation, impaired vascular endothelial growth factor (VEGF)/angiopoietin-Tie (Ang/Tie) signaling, abnormal intercellular communication, and epigenetic memory progressively disrupt the coordinated interactions among NVU components, leading to neurovascular uncoupling. This concept helps explain why retinal functional abnormalities and neurodegenerative changes may precede clinically visible vascular lesions. In this review, we summarize cell-specific NVU alterations and the molecular mechanisms that drive neurovascular uncoupling in DR. We also discuss how this framework may support earlier diagnosis, mechanism-based phenotyping, and stage-adapted treatment strategies. Established therapies, including anti-vascular endothelial growth factor (anti-VEGF) agents, corticosteroids, and angiopoietin-2 (Ang-2)/Tie-2-directed vascular stabilization, are considered together with investigational approaches targeting oxidative stress, inflammation, neuroprotection, metabolic reprogramming, epigenetic regulation, and drug delivery. Reframing DR as a diabetes-driven disorder of early NVU uncoupling may help shift clinical thinking from late vascular rescue toward mechanism-based neurovascular protection, precision phenotyping, and stage-adapted intervention.",

However, existing 2D segmentation methods often suffer from slice-to-slice inconsistencies due to the lack of contextual information across adjacent B-scans. 3D segmentation methods are better for capturing slice-to-slice context, but they require expensive computational resources. To address these limitations, we propose a 2.5D segmentation framework that incorporates a novel cross-slice feature fusion (CFF) module into a U-Net-like architecture. The CFF module fuses inter-slice features to effectively capture contextual information, enabling consistent boundary detection across slices and improved robustness in noisy regions. The framework was validated on both a clinical dataset and the publicly available DUKE DME dataset. Compared to other segmentation methods without the CFF module, the proposed method achieved an 8.56% reduction in mean absolute distance and a 13.92% reduction in root mean square error, demonstrating improved segmentation accuracy and robustness. Overall, the proposed 2.5D framework balances contextual awareness and computational efficiency, enabling anatomically reliable retinal layer delineation for automated glaucoma evaluation and potential clinical applications.",

We used three nationwide health examination surveys conducted in 2000, 2011 and 2017, with a total of 18\u2009966 participants representing the Finnish population aged 18\u2009years and older. All surveys were linked to national health registers covering diagnoses related to diabetes and DR between 2000 and 2017. All surveys included a health examination, in which distance and near VAs were measured. All data were analysed at the individual level. The prevalence of type 2 diabetes increased from 2.6% to 9.6% between 2000 and 2017, while its annual incidence increased from 0.5% to 0.7%. The annual incidence of DR among type 2 diabetes patients decreased from 1.4% to 0.3% between 2000 and 2017. Both distance and near VA were the best among individuals without diabetes, significantly worse among type 2 diabetes patients without DR, and the worst among type 2 diabetes patients with DR. Both distance and near VAs significantly improved between 2000 and 2017 in these study groups. The prevalence of type 2 diabetes has increased during the 2000s, which can be explained by the improved screening and unfavourable changes in lifestyle. However, the incidence of DR has decreased among type 2 diabetes patients, indicating the successful development and effectiveness of screening and therapies for both diabetes and DR.",

Retrospective, observational study of patients with bilateral Acute Retinal Necrosis (BARN) at a tertiary care center in South India from 2016 to 2025. Data collected included demographics, systemic and ocular history, BCVA (converted to logMAR for analysis), treatment modalities (medical and surgical), and complications such as retinal detachment, glaucoma, and phthisis bulbi. BARN was noted in 41 patients out of a total of 319 clinical records of ARN (12.8%). One-third patients (36.5%) had a history of HIV. The mean BCVA improved from 1.37 logMAR at presentation to 1.18 logMAR after a mean follow-up of 38.4\u2009months. Rhegmatogenous retinal detachment (RRD) was the most common complication, affecting 36.5% (30/82) of eyes, with 8 eyes presenting with RRD and 22 developing it during follow-up. Exudative retinal detachment was noted in 7 eyes. Other complications included optic atrophy (10.9%), phthisis bulbi (4.8%), glaucoma (2.4%), and epiretinal membrane (1.2%).

Bilateral acute retinal necrosis is uncommon but has more severe course and results in significant ocular complications and poor visual outcomes underscoring the aggressive nature of the disease.",
        "42461304": "ID: 42461304\nTitle: Global, regional, and national burden of glaucoma, 1990-2023: a systematic analysis of the Global Burden of Disease Study 2023.\nAbstract: This study aims to characterize the spatiotemporal trends in the global glaucoma burden from 1990 to 2023 and project future trends to 2050, informing tailored prevention and control strategies across countries. Age-standardized disability-adjusted life-year (AS-DALY) rates for glaucoma were extracted from the Global Burden of Disease Study 2023 database for 204 countries and territories. Temporal trends from 1990 to 2023 were quantified using the estimated annual percentage change (EAPC), and joinpoint regression was applied to identify significant changes in trend, with average annual percentage change (AAPC) used to summarize overall long-term patterns. Future burden from 2024 to 2050 was projected using an exponential smoothing state-space (ETS/EMS) model. Associations between burden and socio-demographic development were assessed using both Pearson and Spearman correlations with the Socio-demographic Index (SDI). An age-period-cohort framework was further used to evaluate age, period, and cohort effects on glaucoma burden. In 2023, the global glaucoma AS-DALY rate was 7.46 per 100,000, reflecting a 39% decline (-\u20094.74 units) since 1990, despite a 52% rise in absolute DALYs due to population aging. Males exhibited a steeper decline (EAPC\u2009-\u20091.58%) than females (-\u20091.25%). High- and middle-SDI countries neared the minimum burden by 2000 and 2010, respectively, while low-SDI countries showed persistent high rates with partial rebounds. The period 2000-2015 accounted for 41% of the total reduction. Forecasts suggest a mean annual AS-DALY decline of 1.2% from 2023 to 2050, yielding a 27.8% reduction without rebound. Glaucoma exhibits a trajectory of rising cases but declining rates, with significant SDI-related disparities. Low-SDI countries require AI-enabled mass screening and access to generic medications, middle-SDI countries need risk-stratified management and laser trabeculoplasty, and high-SDI countries should focus on normal-tension glaucoma in the elderly. WHAT IS KNOWN: \u25cf Glaucoma remains a leading cause of irreversible blindness worldwide, with its burden historically influenced by aging populations and healthcare disparities across regions. \u25cf Despite a 52% increase in absolute DALYs due to aging, the global age-standardized DALY rate for glaucoma fell by 39% from 1990 to 2023, with males experiencing a steeper decline than females. \u25cf Significant inequalities persist: high-and middle-SDI countries approached minimal burden levels years ago, while low-SDI countries continue to face high rates with occasional rebounds. \u25cf Forecasts predict a continued annual decline of 1.2% in age-standardized burden to 2050, and the study provides specific, tailored prevention strategies for countries at different development levels.",
        "42461351": "ID: 42461351\nTitle: NREP is involved in xenon's protection against ischemic stroke injury through modulating microglial M1 polarization and neuroinflammation.\nAbstract: Ischemic stroke (IS) is associated with high mortality and disability rates, and secondary neuroinflammation is a key driver of exacerbated neuronal damage. Xenon (Xe) exhibits neuroprotective effects, yet the specific mechanism by which it regulates microglia remains unclear. Public transcriptome datasets of human stroke cortex (GSE56267) and Xe-treated microglia (GSE273575) were analyzed, and key genes were screened using machine learning. An oxygen-glucose deprivation/reoxygenation (OGD/R) model was established with human microglial cells (HMC3). NREP expression, microglial polarization, and inflammatory responses were assessed via Western blot, flow cytometry, and ELISA. HMC3 cells were co-cultured with human cortical neurons using Transwell inserts, and neuronal damage was evaluated by CCK-8 assay, kit-based detection, and flow cytometry. Finally, a middle cerebral artery occlusion (MCAO) model was established in rats to investigate the potential involvement of NREP in the neuroprotective effects of Xe in vivo. NREP was identified as a key regulatory gene that was downregulated after stroke and upregulated following Xe treatment. In the OGD/R model, Xe upregulated NREP expression in HMC3 cells, inhibited M1 polarization and proinflammatory cytokine release, and this effect could be partially reversed by NREP silencing. Xe-treated HMC3 cells mitigated apoptosis and oxidative stress in co-cultured neurons, which appeared to be, at least in part, dependent on NREP. In MCAO rats, Xe upregulated NREP in the brain and reduced infarct volume and neuroinflammation. Critically, in vivo knockdown of NREP significantly reversed these neuroprotective and anti-inflammatory effects of Xe. Xe treatment upregulated NREP expression, inhibited M1 polarization of microglia and neuroinflammation, and alleviated cerebral ischemia-reperfusion injury in experimental models. These findings suggest that NREP contributes to xenon-mediated neuroprotection and may serve as a potential therapeutic target, providing preliminary experimental evidence for subsequent translational research of IS.",
        "42461534": "ID: 42461534\nTitle: A hybrid model for early diagnosis of ophthalmology diseases leveraging CNNs, SBOA optimization, and XAI for visualization.\nAbstract: Ophthalmology diseases are among the leading causes of vision loss worldwide. Glaucoma, diabetic retinopathy, and cataracts are the most common diseases and can lead to permanent vision loss if left untreated. In this paper, a new hybrid model has been proposed with the methods accepted in the literature used in the early diagnosis of these diseases. The relationships between imaging analyses and clinical evaluations performed in the diagnostic processes of glaucoma, diabetic retinopathy, and cataract are discussed, and the methods that help to identify diseases in the early stages are emphasized. In addition, the contributions of advanced technologies and imaging systems used in diagnosing these diseases to the developments in the field of eye health are discussed. This article proposes a hybrid model for eye disease detection that combines Convolutional Neural Networks (CNNs) with a metaheuristic optimization algorithm. This model uses ShuffleNet and ResNet101 models as feature extractors, while the Secretary Bird Optimization Algorithm (SBOA) is used for feature selection. Then, the extracted feature maps were combined with ShuffleNet and ResNet101 and optimized with SBOA. The feature fusion process aimed to improve the performance of the developed model by combining different features of the same image. The combined feature map optimized with SBOA was classified into six different classifiers so that the model could work faster and more effectively. Competitive results were produced in the developed model. Finally, explainable artificial intelligence methods were used to visualize the decisions of the developed hybrid model and understand the internal working principle of the model.",

To evaluate baseline anterior segment risk factors associated with progression from PACS to PAC over 5 years. This post hoc analysis involves data from a randomized clinical trial (Singapore Asymptomatic Narrow Angles-Laser Iridotomy Study) conducted at 5 tertiary eye hospitals from November 1, 2004, to October 31, 2018. The original enrollment included 480 participants. Data analysis for this report was conducted from May to July 2025. All participants underwent comprehensive ocular examinations, including anterior segment optical coherence tomography (AS-OCT) and ultrasound biomicroscopy (UBM) at baseline, before laser peripheral iridotomy (LPI), and LPI in 1 randomly selected eye. PACS was diagnosed if the pigmented trabecular meshwork was not visualized for 2 or more quadrants on nonindentation gonioscopy. Progression was defined as development of PAC (intraocular pressure [IOP] >24 mm Hg and/or \u22651 clock hour of peripheral anterior synechiae, or an episode of acute angle closure). Risk factors for progression were assessed using univariable and multivariable generalized linear models (GLMs) with generalized estimating equations and Cox regression models clustered by participant. We estimated odds ratios (ORs) with 95% CI using GLM and hazard ratios (HRs) with 95% CI using Cox regression. Of the 480 participants originally enrolled, 161 (33.5%) underwent baseline AS-OCT and UBM. Among these participants, 123 (76.4%) were female and 38 (23.6%) male; the mean (SD) age was 62.9 (7.2) years. Overall, 16 of 322 eyes (5.0%, 7 with LPI and 9 without LPI) progressed. In the multivariable GLM model (area under the receiver operating characteristic curve\u2009=\u20090.83), higher baseline IOP (OR, 1.6 per 1 mm Hg; 95% CI, 1.2-2.1; P\u2009=\u2009.003) or a higher number of plateau iris quadrants on UBM (OR, 4.5 per quadrant; 95% CI, 1.6-13.0; P\u2009=\u2009.005) were associated with progression. In the multivariable Cox model adjusted for baseline IOP, trabecular-iris space area (TISA750; HR, 3.1 per -0.1 mm2; 95% CI, 1.3-7.5; P\u2009=\u2009.02) or the presence of plateau iris in \u22651 quadrant (HR, 11.1; 95% CI, 3.3-37.7; P\u2009=\u2009.001) were independently associated with greater risk of progression. An additional Cox model adjusting for iris curvature confirmed the associations of TISA750 (HR, 3.3; 95% CI, 1.3-8.6; P\u2009=\u2009.02) or plateau iris (HR, 12.5; 95% CI, 3.8-40.4; P\u2009<\u2009.001) with progression. Narrower anterior chamber angles, plateau iris configuration in more than 1 quadrant, or higher baseline IOP were associated with greater risk of progression.

Ocular involvement often occurs early and may be a prominent, sight-threatening feature. Despite this, COS is sparsely described in the literature. This case series aims to characterise the ocular manifestations, complications, and outcomes in COS. A review of patients diagnosed with COS under a tertiary paediatric uveitis service. Data collected included age at onset, clinical findings, diagnostic methods, treatments, ocular complications, and visual acuity (VA) at presentation and last follow-up. Six patients were identified, all of whom presented with granulomatous uveitis. Four had posterior segment involvement including choroiditis and optic disc swelling. The mean age of ocular disease onset was 7\u2009years. Diagnosis was supported by elevated serum angiotensin converting enzyme (ACE) followed by lymph node biopsy (n\u2009=\u20093), skin biopsy (n\u2009=\u20092), and/or NOD2 mutation (n\u2009=\u20093). All received systemic immunosuppression: methotrexate (n\u2009=\u20096), adalimumab (n\u2009=\u20095), mycophenolate (n\u2009=\u20092), oral corticosteroids (n\u2009=\u20093), and infliximab (n\u2009=\u20091). Complications included uveitic glaucoma (n\u2009=\u20092), cataract (n\u2009=\u20093), and chorioretinal scarring (n\u2009=\u20091). VA improved or remained stable in most, with one case of persistent visual impairment.

Careful ophthalmic screening in children with known or suspected sarcoidosis is critical.",
        "42461929": "ID: 42461929\nTitle: Long-Acting RXR Agonism Preserves Retinal Function and Modulates Inflammation in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss and is associated with reduced nuclear retinoid X receptor (RXR) activity. Retinal explants exposed to high glucose showed downregulation of RXR, peroxisome proliferator-activated receptor (PPAR), and liver X receptor-\u03b2 and their lipid metabolism targets (Abca1, Scd1, and Acox1). Supplementation with the RXR agonist UAB126 restored nuclear receptor signaling and preferentially activated RXR/PPAR heterodimers. We evaluated UAB126 microparticles (UAB126-MP), a sustained-release RXR agonist formulation, for pharmacokinetic, molecular, and functional effects in db/db mouse retinas. A single intravitreal injection of UAB126-MP provided extended drug exposure for up to 6 months and increased retinal RXR\u03b1 expression. Functionally, UAB126-MP preserved scotopic and photopic electroretinographic responses at 2 months and sustained cone photoreceptor function at 6 months. However, it did not reduce acellular capillaries. At 6 months, immunostaining and flow cytometry revealed decreased retinal macrophage/microglial infiltration and reduced CD45-positive myeloid cells and monocytes. These findings indicate that RXR agonism supports neuronal protection and immune modulation but does not prevent vasodegeneration, suggesting primarily neuroprotective and anti-inflammatory actions. Collectively, UAB126-MP confers durable retinal protection through nuclear receptor-mediated pathways, underscoring its potential as a long-acting therapeutic strategy for DR. High glucose exposure of retinal explants reduces expression of nuclear receptors retinoid X receptor (RXR), peroxisome proliferator-activated receptor, and liver X receptor-\u03b2, and treatment with UAB126 increases the formation of RXR-peroxisome proliferator-activated receptor heterodimers. Sustained release of UAB126-loaded microparticles enables intravitreal drug delivery for up to 6 months. Intravitreal UAB126 microparticles injection in diabetic mice confers long-term neuroprotection and anti-inflammatory benefits. RXR-targeted therapy represents a promising approach strategy for managing diabetic retinopathy.",
        "42461932": "ID: 42461932\nTitle: Structure function relationships differ between optic neuritis and glaucoma with comparable optical coherence tomography findings.\nAbstract: This retrospective study compared structure-function relationships between patients with optic neuritis (ON) and primary open-angle glaucoma (POAG), focusing on the extent of retinal nerve fiber layer (RNFL) and ganglion cell-inner plexiform layer (GCIPL) damage and its correlation with visual field (VF) defects. We included 194 patients (ON: 47; POAG: 147) referred to Yonsei University Severance Eye Hospital between 2017 and 2023. RNFL and GCIPL thickness, VF indices, and the relationship between structural and functional measures were assessed. Despite comparable RNFL and GCIPL thinning, ON demonstrated significantly better VF performance than POAG (mean deviation: -2.26 dB vs. -7.32 dB; VF index: 95.48% vs. 80.43%; both p\u2009<\u20090.001). In POAG, VF loss was strongly correlated with structural parameters, whereas in ON, VF remained preserved even at low RNFL and GCIPL values. Linear regression with robust error estimation confirmed significant interaction between disease type and structure-function slopes (p\u2009<\u20090.01). These findings persisted after 1:2 propensity score matching for age and comorbidities (ON: n\u2009=\u200929; POAG: n\u2009=\u200958; all interaction p\u2009<\u20090.05), age-adjusted multivariable regression, and a sensitivity analysis restricted to non-diabetic participants (ON: n\u2009=\u200945; POAG: n\u2009=\u2009124; all interaction p\u2009<\u20090.001). This dissociation was evident at RNFL <90 \u00b5m and GCIPL <80 \u00b5m, where ON showed better VF indices than POAG with similar structural loss. The differences in structure-function relationships underscore the importance of disease-specific diagnostic approaches and unraveling the distinct mechanisms underlying ON and POAG to improve the management of visual impairments."
