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.

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.

Diabetes was induced using a high-fat, high-sugar (HFHS) diet combined with streptozotocin (STZ). Diabetes was induced in C57BL/6J mice using an HFHS diet followed by STZ. POCD was modeled via tibial fracture surgery under general anesthesia. Cognitive function was assessed using the Open Field Test, Y-maze, and contextual fear conditioning. cGAS-STING pathway activation was evaluated by western blot for cGAS and STING expression. Microglial activation was assessed by co-localization of Iba-1 and CD68 by immunofluorescence, and the co-localization of STING with Iba-1 in the hippocampus was examined by immunofluorescence. Hippocampal neuroinflammation was quantified by enzyme-linked immunosorbent assay (ELISA) for interleukin-1beta (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1). Neuronal injury and apoptosis were evaluated by Nissl staining and western blot for cleaved caspase-3. Compared to non-diabetic controls, diabetic mice exhibited cognitive impairments, which were more pronounced in those that underwent surgery. This was accompanied by significant hippocampal neuronal loss, upregulated cleaved caspase-3 expression, and elevated IL-1\u03b2 and TNF-\u03b1 levels. Furthermore, diabetic mice that underwent surgery displayed increased expression of microglial activation markers (Iba-1 and CD68) and evidence of cGAS-STING pathway activation in the hippocampus. Immunofluorescence co-localization experiments further suggested a predominant association of this pathway with the microglial marker Iba-1. These findings suggest that surgery-associated overactivation of the microglial cGAS-STING pathway in the hippocampus may exacerbate neuroinflammation and neuronal injury, thereby contributing to cognitive decline in diabetic mice."

Fatty acid binding protein 5 (FABP5), a lipid chaperone, has been implicated in chronic inflammation. However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells. Deletion of astrocytic Fabp5 significantly attenuated pyroptosis, neuronal loss, and seizure activity in epilepsy. Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis. Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Pharmacological inhibition of mitochondrial fatty acid import recapitulated these protective effects. In contrast, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. Collectively, these findings revealed the regulatory role of FABP5-cGAS-STING-pyroptosis axis in the progression of epilepsy and highlighted the promising potential of astrocytic FABP5 as a therapeutic target for epilepsy."

Notably, the clinical efficacy of current interventions is severely restricted by post-ischemic neuroinflammation. Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA. Three-prime repair exonuclease 1 (TREX1), a cytosolic DNA exonuclease, negatively regulates STING signaling; however, efficient delivery of TREX1 to the ischemic brain remains a major challenge. Here, we engineered mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) as carriers for TREX1 delivery. This was accomplished by using a palmitoylation signal-fused construct (PALM-TREX1), which enables efficient loading of the protein into extracellular vesicles. The C1C2 domains of lactadherin and the RGD-4C peptide were combined into a single recombinant fusion protein, enabling EV surface functionalization for enhanced ischemic targeting via phosphatidylserine interaction. In a mouse model of middle cerebral artery occlusion (MCAO), RGD-modified TREX1-loaded EVs (RGD-EV-TREX1) preferentially accumulated in ischemic regions, suppressed STING pathway activation, and reduced microglial activation and pro-inflammatory cytokine expression. The reduction in neuronal DNA damage and apoptosis ultimately facilitated improved neurological functional recovery, positioning RGD-EV-TREX1 as a promising cell-free therapeutic strategy for ischemic stroke."

Ring-finger protein 5 (RNF5) is an important modulator of STING and is implicated in various disease processes. Nevertheless, the function of RNF5/STING axis in the context of DKD has yet to be investigated. This research was undertaken to explore whether RNF5 regulates the progression of DKD through modulation of the STING pathway, as well as to clarify the mechanisms involved. We found that RNF5 levels were significantly reduced in high glucose (HG)-stimulated HK-2 cells and the kidneys of diabetic mice. Upregulation of RNF5 inhibited HG-induced cellular injury, fibrosis, and inflammatory responses, while RNF5 knockdown exacerbated these detrimental effects. Moreover, HG treatment led to increased levels of STING, phosphorylated TBK1, phosphorylated IRF-3, and phosphorylated NF-\u03baB, indicating STING pathway activation. RNF5 overexpression significantly suppressed the activation of the STING pathway induced by HG, whereas RNF5 knockdown enhanced it. Mechanistically, RNF5 promoted the ubiquitination and degradation of STING. Inhibition of STING abolished the exacerbating effect of RNF5 knockdown on HG-induced cellular injury. Animal studies revealed that RNF5 overexpression alleviated kidney damage, fibrosis, and inflammation in diabetic mouse models, concomitantly suppressing STING pathway activation. Collectively, RNF5 inhibits HG-induced tubular cell injury by promoting STING degradation, thereby suppressing STING pathway activation. Targeting RNF5 could be a potentially effective therapeutic approach for DKD."

While the survival benefit of TTFields was established by the EF-14 phase III trial, their biological effects extend well beyond the canonical anti-mitotic mechanism and encompass extensive interactions with the GBM tumor microenvironment (TME). This review provides an integrated mechanistic analysis of TTFields-TME interactions in GBM, with a distinctive focus on their convergence with radiotherapy. We examine how TTFields activate innate immune sensing through cGAS/STING and AIM2 inflammasome pathways, drive immunogenic cell death, reprogram tumor-associated macrophages, and prime adaptive T cell responses. We further address TTFields effects on glioma stem cells, blood-brain barrier permeability, and intracellular signaling governing invasion, angiogenesis, and autophagy. Critically, we develop the mechanistic and clinical case for TTFields-radiotherapy combinations, highlighting convergent mechanisms of DNA repair impairment, mitotic catastrophe, and innate immune activation. Practical considerations for concurrent clinical implementation are discussed alongside a research agenda centered on optimal timing, hypofractionation, and predictive biomarkers. Available evidence-largely preclinical-suggests that TTFields may act as a TME-remodeling platform whose potential is most likely to be realized through mechanistically informed combinations."

BV2 cells were divided into three groups: control group (no treatment), pyroptosis group [stimulated with 1 \u03bcg/mL lipopolysaccharide (LPS) for 12 hours, followed by 10 \u03bcmol/L nigericin (Nig) treatment for 1 hour], and T\u03b24 treatment group (co-incubated with LPS and Nig, then treated with 1 \u03bcg/mL T\u03b24 for 1 hour). An in vitro sepsis-associated encephalopathy model was established by LPS and Nig co-treatment. Viability of BV2 cells was assessed by CCK-8 assay. RT-qPCR was performed to detect mRNA expression of interleukin (IL)-1\u03b2, interferon-induced protein with tetratricopeptide repeats 1 (IFIT1), and interferon-\u03b2 (IFN-\u03b2). IL-1\u03b2 levels in cell supernatants were measured by ELISA. Protein expression of NLRP3, GSDMD-N, cleaved caspase-1, phosphorylated stimulator of interferon genes (p-STING), and phosphorylated interferon regulatory factor 3 (p-IRF3) was analyzed by Western blot. Cell death rate and mitochondrial reactive oxygen species (ROS) levels were detected by flow cytometry using propidium iodide staining and MitoSOX indicator, respectively. Compared with the pyroptosis group, T\u03b24 treatment alleviated morphological damage caused by pyroptosis in BV2 cells. Intracellular mRNA expression of IL-1\u03b2, IFIT1, and IFN-\u03b2; IL-1\u03b2 concentration in supernatant; protein expression of NLRP3, GSDMD-N, cleaved caspase-1, p-STING, and p-IRF3; cell death rate; and mitochondrial ROS levels were significantly decreased (P0.05). T\u03b24 protects BV2 microglial cells against LPS and Nig-induced pyroptosis by inhibiting oxidative stress and inflammatory responses, potentially through regulation of the cGAS-STING signaling pathway. \u76ee\u7684: \u63a2\u7a76\u80f8\u817a\u7d20\u03b24\uff08thymosin beta 4, T\u03b24\uff09\u5bf9BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\u7126\u4ea1\u7684\u4fdd\u62a4\u4f5c\u7528\u53ca\u5206\u5b50\u673a\u5236\u3002\u65b9\u6cd5: \u5c06BV2\u7ec6\u80de\u5206\u4e3a\u5bf9\u7167\u7ec4\uff08\u4e0d\u4f5c\u4efb\u4f55\u5904\u7406\uff09\u3001\u7126\u4ea1\u7ec4[1 \u03bcg/mL\u8102\u591a\u7cd6\uff08lipopolysaccharide, LPS\uff09\u523a\u6fc012 h\u540e\uff0c\u7ed9\u4e8810 \u03bcmol/L\u5c3c\u65e5\u5229\u4e9a\u83cc\u7d20\uff08Nigericin, Nig\uff09\u5904\u74061 h]\u3001T\u03b24\u5904\u7406\u7ec4\uff08\u540c\u6b65\u7ed9\u4e88LPS\u3001Nig\u540e\uff0c1 \u03bcg/mL T\u03b24\u5904\u74061 h\uff09\u3002\u901a\u8fc7LPS\u8054\u5408Nig\u5904\u7406BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\uff0c\u6784\u5efa\u8113\u6bd2\u75c7\u76f8\u5173\u6027\u8111\u75c5\u4f53\u5916\u6a21\u578b\u3002\u91c7\u7528CCK\u20118\u6cd5\u68c0\u6d4bT\u03b24\u5bf9BV2\u7ec6\u80de\u7684\u7ec6\u80de\u6d3b\u529b\uff0c\u53cd\u8f6c\u5f55\u5b9e\u65f6\u8367\u5149\u5b9a\u91cfPCR\u6cd5\u68c0\u6d4b\u767d\u7ec6\u80de\u4ecb\u7d20\uff08interleukin, IL\uff09\u20111\u03b2\u3001\u5e72\u6270\u7d20\u8bf1\u5bfc\u86cb\u767d\u56db\u80bd\u91cd\u590d\u5e8f\u52171\u3001\u03b2\u5e72\u6270\u7d20mRNA\u8868\u8fbe\u6c34\u5e73\uff0c\u9176\u8054\u514d\u75ab\u5438\u9644\u8bd5\u9a8c\u68c0\u6d4b\u7ec6\u80de\u4e0a\u6e05\u6db2\u4e2dIL\u20111\u03b2\u6c34\u5e73\uff0cWestern blot\u6cd5\u68c0\u6d4bNOD\u6837\u53d7\u4f53\u70ed\u86cb\u767d\u7ed3\u6784\u57df\u76f8\u5173\u86cb\u767d3\u3001\u6d88\u76ae\u7d20D N\u7aef\u7247\u6bb5\u3001\u5207\u5272\u578b\u80f1\u5929\u86cb\u767d\u91761\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u57fa\u56e0\u523a\u6fc0\u56e0\u5b50\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u8c03\u8282\u56e0\u5b503\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff0c\u6d41\u5f0f\u7ec6\u80de\u672f\u7ed3\u5408\u7898\u5316\u4e19\u5576\u67d3\u8272\u68c0\u6d4b\u7ec6\u80de\u6b7b\u4ea1\u7387\uff0cMitoSOX\u8367\u5149\u6307\u793a\u5242\u68c0\u6d4b\u7ec6\u80de\u7ebf\u7c92\u4f53\u6d3b\u6027\u6c27\u6c34\u5e73\u3002\u7ed3\u679c: \u4e0e\u7126\u4ea1\u6a21\u578b\u7ec4\u6bd4\u8f83\uff0cT\u03b24\u5904\u7406\u7ec4BV2\u7ec6\u80de\u7126\u4ea1\u5f62\u6001\u635f\u4f24\u51cf\u8f7b\uff0c\u7ec6\u80de\u5185IL\u20111\u03b2\u3001\u5e72\u6270\u7d20\u8bf1\u5bfc\u86cb\u767d\u56db\u80bd\u91cd\u590d\u5e8f\u52171\u3001\u03b2\u5e72\u6270\u7d20mRNA\u8868\u8fbe\u4e0e\u7ec6\u80de\u4e0a\u6e05IL\u20111\u03b2\u542b\u91cf\u3001NOD\u6837\u53d7\u4f53\u70ed\u86cb\u767d\u7ed3\u6784\u57df\u76f8\u5173\u86cb\u767d3\u3001\u6d88\u76ae\u7d20D N\u7aef\u7247\u6bb5\u3001\u5207\u5272\u578b\u80f1\u5929\u86cb\u767d\u91761\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u57fa\u56e0\u523a\u6fc0\u56e0\u5b50\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u8c03\u8282\u56e0\u5b503\u86cb\u767d\u8868\u8fbe\u53ca\u7ec6\u80de\u6b7b\u4ea1\u7387\u3001\u7ebf\u7c92\u4f53\u6d3b\u6027\u6c27\u6c34\u5e73\u964d\u4f4e\uff08P0.05\uff09\u3002\u7ed3\u8bba: T\u03b24\u53ef\u6539\u5584LPS+Nig\u8bf1\u5bfc\u7684BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\u7126\u4ea1\u635f\u4f24\uff0c\u6291\u5236\u6c27\u5316\u5e94\u6fc0\u4e0e\u708e\u75c7\u53cd\u5e94\uff0c\u5176\u673a\u5236\u53ef\u80fd\u4e0ecGAS\u2011STING\u4fe1\u53f7\u901a\u8def\u6709\u5173\u3002."

The stimulator of interferon genes (STING) pathway is emerging as a central driver of microglial activation and inflammatory damage. However, therapeutic strategies targeting this pathway are limited. We investigated the neuroprotective effects of senegenin, a bioactive natural compound, in a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model and N9 microglia subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Behavioral, histological, and biochemical analyses were performed to assess neurological outcomes, infarct volume, microglial activation, and neuroinflammatory response. Mechanistic studies evaluated the effects of senegenin on STING-TBK1-IRF3 signaling, NF\u03baB-dependent NLRP3 inflammasome activation, pyroptosis, and apoptosis. Molecular docking, dynamics simulations, and pharmacological validation with the STING agonist DMXAA were used to confirm direct STING inhibition. Senegenin treatment significantly improved neurological outcomes, decreased infarct volume, and preserved cortical and hippocampal neurons. It attenuated oxidative stress, reduced DNA damage, and inhibited microglial activation. Mechanistically, senegenin suppressed STING activation and downstream phosphorylation of TBK1 and IRF3, blocked NF-\u03baB/NLRP3-mediated pyroptosis, and inhibited apoptotic death by modulating Bcl2 and BAX expression. Molecular docking predicted stable binding of senegenin to STING, and DMXAA experiments confirmed direct inhibition of STING signaling as the mechanistic basis of its neuroprotective effects. This study demonstrates that senegenin confers potent neuroprotection in ischemic stroke by attenuating regulated cell death pathways through direct inhibition of STING, highlighting its ability as a promising therapeutic candidate for STING-targeted interventions in ischemic stroke and related neuroinflammatory disorders."

Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field."

However, the underlying mechanisms linking metabolic disorders and immune damage remain unclear. In a TCE-sensitized mouse model, we demonstrated that TCE sensitization inhibited LKB1/AMPK/mTOR signaling pathway (LKB1 overexpression, AICAR, rapamycin) or autophagy (3-MA) in hepatocytes, resulting in defective mitophagy. This mitochondrial dysfunction leads to leakage of mitochondrial DNA (mtDNA) into the cytoplasm, where mtDNA acts as a damage-associated molecular pattern (DAMP) to activate the cGAS-STING pathway, driving the production of proinflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and exacerbating liver inflammation. Restoration of LKB1/AMPK signaling or inhibition of mTOR rescued mitophagi, reduced mitochondrial DNA leakage, inhibited cGAS-STING activation, and alleviated liver pathology, while inhibition of autophagy alone recapitulated the TCE-induced phenotype. Taken together, our findings demonstrate that failure of TCE via LKB1/AMPK/mTOR mediated mitophagy destroys hepatocyte homeostasis, leading to mtDNA-driven cGAS-STING activation and immune-mediated liver injury in the pathogenesis of OMDT, thus providing a potential therapeutic target for OMDT-related liver injury."

Mitochondrial DNA (mtDNA) leakage activates the cGAS-STING pathway, triggering excessive inflammatory responses and hindering osteogenesis. Concurrently, defective mitophagy exacerbates mitochondrial damage, perpetuating a cycle of bone loss. This study investigated the role of the mtDNA-cGAS-STING axis in lipopolysaccharide (LPS)-induced bone marrow mesenchymal stem cells (BMSCs) dysfunction and inflammatory bone loss. We exposed BMSCs to LPS and assessed mitochondrial function, mtDNA release, and cGAS-STING activation using RT-qPCR, Western blotting, and immunofluorescence. We then engineered exosomes to co-deliver siRNA targeting STING and PINK1 mRNA, testing their effects on osteogenesis and mitochondrial homeostasis in vitro and in a mouse model of LPS-induced osteoporosis. LPS exposure resulted in mitochondrial damage, mtDNA leakage, and cGAS-STING activation, impairing osteogenic differentiation and increasing inflammatory cytokine expression. While STING inhibition reduced inflammatory signaling, it did not restore mitochondrial function, whereas PINK1 overexpression improved mitophagy and partially suppressed cGAS-STING activation. Dual regulation through siSTING/PINK1@Exo synergistically reduced mitochondrial ROS, restored membrane potential, promoted osteogenic marker expression, and enhanced mineralization in vitro. Dual-regulated exosomes significantly improved trabecular bone microarchitecture, reduced STING expression, and enhanced RUNX2 and OCN expression compared to single treatments through in vivo model. These results demonstrate that combining mitophagy activation with STING inhibition via engineered exosomes offers a promising therapeutic strategy for inflammatory osteoporosis by addressing both mitochondrial dysfunction and chronic inflammation."

This review summarizes current knowledge of cGAS-STING signaling in CNS disorders and evaluates its therapeutic potential. Relevant studies on cGAS-STING signaling in CNS disorders were collected from PubMed and Web of Science, with emphasis on disease mechanisms, neuroinflammatory regulation, and pathway-targeted therapeutic strategies. In the CNS, cGAS-STING signaling exhibits marked region-, cell-, and pathology-dependent heterogeneity. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. Pharmacological inhibition of cGAS, cyclic GMP-AMP (cGAMP), or STING, together with emerging delivery strategies, has shown promise in preclinical models. Clinical translation remains limited by incomplete validation of pathway specificity, limited human evidence, restricted brain delivery, and inconsistent efficacy assessment. The cGAS-STING pathway links aberrant DNA sensing to innate immune activation and CNS pathology. Clarifying its disease-, cell-, and stage-specific roles may support future targeted therapeutic strategies for CNS disorders."

Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH. This work establishes a novel biomimetic nanomedicine strategy for SAH therapy and opens new avenues for treating neuroinflammation-related disorders."

Pemetrexed, an antifolate chemotherapeutic agent, has documented immunomodulatory effects in \u03b1\u03b2 T-cell settings; however, its impact on \u03b3\u03b4 T-cell antitumor responses remains insufficiently defined. Here, V\u03b39V\u03b42 T cells were isolated and expanded from healthy-donor peripheral blood mononuclear cells (PMBCs) and co-cultured with non-small cell lung cancer (NSCLC) cells with or without pemetrexed pretreatment. Pemetrexed significantly enhanced \u03b3\u03b4 T cell-mediated cytotoxicity compared with either treatment alone. Mechanistically, pemetrexed increased the expression of NKG2D ligands, including MHC class I chain-related proteins A/B (MICA/B) and UL16-binding proteins (ULBPs), through the ataxia-telangiectasia mutated (ATM)-stimulator of interferon genes (STING)-nuclear factor-\u03baB (NF-\u03baB) signaling axis. ATM activation triggered cyclic GMP-AMP synthase-independent STING signaling and preferentially activated NF-\u03baB rather than interferon regulatory factor 3 (IRF3), thereby promoting transcriptional upregulation of NKG2D ligands and improving tumor recognition by \u03b3\u03b4 T cells. Consistent with the cell-line findings, pemetrexed increased MICA/B and ULBP2/5/6 expression in NSCLC patient-derived organoids. Furthermore, in an in vivo NSCLC animal model, combined pemetrexed and adoptive \u03b3\u03b4 T-cell therapy suppressed tumor growth more effectively than either treatment alone and was accompanied by increased NKG2D ligand expression. Collectively, these findings reveal a tumor-sensitizing mechanism by which pemetrexed potentiates \u03b3\u03b4 T-cell antitumor function and support combining pemetrexed with \u03b3\u03b4 T cell-based immunotherapy for NSCLC."

This study investigated the radiosensitizing effects of either 7-day 30% caloric restriction (CR) or 24-hour fasting in a murine model bearing CT-26 colorectal tumor and explored the underlying mechanisms. CR and fasting pretreatment enhanced irradiation-induced tumor apoptosis, mitochondrial dysfunction, and cytosolic DNA stress, leading to activation of the cyclic GMP-AMP synthase/stimulator of interferon gene (cGAS-STING) pathway, increased infiltration of tumor killing-associated CD8\u2009+\u2009cytotoxic T lymphocytes, and modulation of macrophage polarization toward an antitumor phenotype. In addition, CR and fasting further suppressed the expression of glycolysis and lipid metabolism related proteins in the tumor microenvironment upon radiation exposure. By contrast, CR and fasting protected normal intestinal tissue from irradiation-induced damage. These findings were validated in vitro using CT-26 and normal small intestinal epithelial cells (IEC-6) cultured under medium with or without glucose. The critical role of the cGAS-STING pathway in enhancing radiosensitivity was confirmed through STING siRNA-mediated knockdown, combined with pharmacological intervention using the STING agonist MSA-2 and inhibitor H-151.

While plati-num-based chemotherapy can trigger antitumor immunity via immunogenic cell death (ICD), its clinical efficacy is often hampered by the intrinsic immunosuppressive milieu and insufficient drug accumulation at the tumor site following systemic administration. To address these challenges, we fabricated a syringeable hyaluronic acid-based hydrogel co-loaded with Cisplatin (CDDP) and STING agonist MSA-2 (CDDP/MSA-2@Gel) for enhanced localized chemoimmunotherapy. The sustained local release of CDDP and MSA-2 synergistically boost stimulator of interferon genes (STING) pathway activation, thereby eliciting potent type-I-IFN-driven systemic antitumor immune responses and alleviating the immunosuppressive TME. In vivo studies demonstrated that CDDP/MSA-2@Gel treatment significantly inhibits tumor growth in murine ovarian cancer models without systemic toxicity.Collectively, our designed CDDP/MSA-2@Gel represents a safe and potent strategy for enhanced synergistic chemoimmunotherapy, offering significant potential for clinical translation in the treatment of ovarian cancer."

However, the underlying mechanisms remain poorly understood. As a key regulator of both neuroinflammation and cellular senescence, Cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is implicated in pathogenesis induced by T. gondii infection. Here, we found that cGAS-STING pathway was activated in the cerebral cortex of mouse chronically infected with T. gondii, as indicated by the elevated protein levels of cGAS and STING, and increased phosphorylation of TBK1 and IRF3. Pharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage. Moreover, chronic T. gondii infection was shown to trigger senescence characterized by increased expression of senescence markers P16, P21 and P53, and senescence-associated secretory phenotypes (SASPs), including Il-1\u03b2, Il-6, Tnf-\u03b1, Cxcl1, Cxcl10 and Mmp9. In addition, elevated expression of \u03b2-galactosidase, a senescence marker, was predominantly observed in neurons compared to microglia and astrocytes, indicating a primary role for neurons in infection-associated senescence. Notably, these phenotypes of senescence were rescued by inhibition of the cGAS-STING pathway. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases."

However, selective STING activation and its quantitative comparison across heterogeneous cell populations remain a tremendous challenge. Herein, we engineered a type of selective STING-activating polysaccharide immunomodulators (SSAPIs) with quantitative STING activation efficiency across tumor cell, macrophage, and dendritic cell (DC). Dextran as an immune cell targeting nanocarrier was employed to improve drug delivery to macrophage and DC, and to avoid the impact of macromolecular self-assembly on drug release kinetics. The STING agonist (DMXAA) was conjugated to dextran via defined linkers to control the selectivity of STING activation in different cell populations. In vitro experiments quantitively revealed the enhanced STING activation of the ester linker SSAPI (DESX) in macrophage, while the disulfide linker SSAPI (DSSX) prompted STING activation across tumor cell and immune cell. In B16F10 and CT26 tumor-bearing mice models, DSSX exhibited much superior antitumor efficacy with six out of eight complete tumor remission by inducing broad immune responses across diverse cell populations to reprogram TIME.

Intriguingly, OTM under periodontitis conditions orchestrates a complex inflammatory microenvironment and exacerbates bone resorption. Stimulator of interferon genes (STING) is a key inflammation mediator, but its role in OTM with periodontitis was unclear. We established an OTM model in rats with ligature-induced periodontitis. In vitro, rat periodontal ligament fibroblasts (PDLFs) were subjected to compressive stress and LPS to mimic orthodontic force and periodontitis inflammation. STING was activated with agonists (cGAMP/diABZI) or inhibited with H151 or knockdown. Inflammatory responses and bone resorption were assessed. RNA sequencing and co-IP followed by LC-MS/MS were used to identify downstream signals. STING activation in PDLFs increased IL-1\u03b2 and IL-6 while reducing Runx-2 and osteogenesis. In periodontitis-OTM rats, STING, IL-1\u03b2 and IL-6 were upregulated and Runx-2 downregulated on the compression side, leading to increased alveolar bone loss that was rescued by H151. Under mechanical-inflammatory stress, activated STING triggered ER stress, and a cascade of cellular responses including increased pro-inflammatory mediators, enhanced apoptosis, altered mechano-response, and suppressed osteogenesis. Meanwhile, Annexin A2 (Anxa2) was identified as a novel STING interactor. Anxa2 knockdown mirrored STING inhibition, suppressing ER stress, inflammatory activation, apoptosis and mechano-response. Mechanistically, Anxa2 knockdown markedly reduced P65 phosphorylation and nuclear translocation, suggesting Anxa2 may serve as an intermediary linking STING to NF-\u03baB activation. STING-Anxa2 interaction was notably increased in PDLFs and in compression-side periodontal tissues under mechanical-inflammatory stress. Within an inflammatory milieu, STING activation in PDLFs is associated with ER stress, pro-inflammatory responses, apoptosis, and suppressed osteogenesis that collectively accelerate bone resorption during OTM. We identified Annexin A2 (Anxa2) as a novel STING interactor whose knockdown attenuated these responses and NF-\u03baB activation, suggesting Anxa2 as a functional intermediary in STING-mediated inflammation."

Notably, the clinical efficacy of current interventions is severely restricted by post-ischemic neuroinflammation. Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA. Three-prime repair exonuclease 1 (TREX1), a cytosolic DNA exonuclease, negatively regulates STING signaling; however, efficient delivery of TREX1 to the ischemic brain remains a major challenge. Here, we engineered mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) as carriers for TREX1 delivery. This was accomplished by using a palmitoylation signal-fused construct (PALM-TREX1), which enables efficient loading of the protein into extracellular vesicles. The C1C2 domains of lactadherin and the RGD-4C peptide were combined into a single recombinant fusion protein, enabling EV surface functionalization for enhanced ischemic targeting via phosphatidylserine interaction. In a mouse model of middle cerebral artery occlusion (MCAO), RGD-modified TREX1-loaded EVs (RGD-EV-TREX1) preferentially accumulated in ischemic regions, suppressed STING pathway activation, and reduced microglial activation and pro-inflammatory cytokine expression. The reduction in neuronal DNA damage and apoptosis ultimately facilitated improved neurological functional recovery, positioning RGD-EV-TREX1 as a promising cell-free therapeutic strategy for ischemic stroke."

Ring-finger protein 5 (RNF5) is an important modulator of STING and is implicated in various disease processes. Nevertheless, the function of RNF5/STING axis in the context of DKD has yet to be investigated. This research was undertaken to explore whether RNF5 regulates the progression of DKD through modulation of the STING pathway, as well as to clarify the mechanisms involved. We found that RNF5 levels were significantly reduced in high glucose (HG)-stimulated HK-2 cells and the kidneys of diabetic mice. Upregulation of RNF5 inhibited HG-induced cellular injury, fibrosis, and inflammatory responses, while RNF5 knockdown exacerbated these detrimental effects. Moreover, HG treatment led to increased levels of STING, phosphorylated TBK1, phosphorylated IRF-3, and phosphorylated NF-\u03baB, indicating STING pathway activation. RNF5 overexpression significantly suppressed the activation of the STING pathway induced by HG, whereas RNF5 knockdown enhanced it. Mechanistically, RNF5 promoted the ubiquitination and degradation of STING. Inhibition of STING abolished the exacerbating effect of RNF5 knockdown on HG-induced cellular injury. Animal studies revealed that RNF5 overexpression alleviated kidney damage, fibrosis, and inflammation in diabetic mouse models, concomitantly suppressing STING pathway activation. Collectively, RNF5 inhibits HG-induced tubular cell injury by promoting STING degradation, thereby suppressing STING pathway activation. Targeting RNF5 could be a potentially effective therapeutic approach for DKD."

Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field."

However, the underlying mechanisms linking metabolic disorders and immune damage remain unclear. In a TCE-sensitized mouse model, we demonstrated that TCE sensitization inhibited LKB1/AMPK/mTOR signaling pathway (LKB1 overexpression, AICAR, rapamycin) or autophagy (3-MA) in hepatocytes, resulting in defective mitophagy. This mitochondrial dysfunction leads to leakage of mitochondrial DNA (mtDNA) into the cytoplasm, where mtDNA acts as a damage-associated molecular pattern (DAMP) to activate the cGAS-STING pathway, driving the production of proinflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and exacerbating liver inflammation. Restoration of LKB1/AMPK signaling or inhibition of mTOR rescued mitophagi, reduced mitochondrial DNA leakage, inhibited cGAS-STING activation, and alleviated liver pathology, while inhibition of autophagy alone recapitulated the TCE-induced phenotype. Taken together, our findings demonstrate that failure of TCE via LKB1/AMPK/mTOR mediated mitophagy destroys hepatocyte homeostasis, leading to mtDNA-driven cGAS-STING activation and immune-mediated liver injury in the pathogenesis of OMDT, thus providing a potential therapeutic target for OMDT-related liver injury."

Mitochondrial DNA (mtDNA) leakage activates the cGAS-STING pathway, triggering excessive inflammatory responses and hindering osteogenesis. Concurrently, defective mitophagy exacerbates mitochondrial damage, perpetuating a cycle of bone loss. This study investigated the role of the mtDNA-cGAS-STING axis in lipopolysaccharide (LPS)-induced bone marrow mesenchymal stem cells (BMSCs) dysfunction and inflammatory bone loss. We exposed BMSCs to LPS and assessed mitochondrial function, mtDNA release, and cGAS-STING activation using RT-qPCR, Western blotting, and immunofluorescence. We then engineered exosomes to co-deliver siRNA targeting STING and PINK1 mRNA, testing their effects on osteogenesis and mitochondrial homeostasis in vitro and in a mouse model of LPS-induced osteoporosis. LPS exposure resulted in mitochondrial damage, mtDNA leakage, and cGAS-STING activation, impairing osteogenic differentiation and increasing inflammatory cytokine expression. While STING inhibition reduced inflammatory signaling, it did not restore mitochondrial function, whereas PINK1 overexpression improved mitophagy and partially suppressed cGAS-STING activation. Dual regulation through siSTING/PINK1@Exo synergistically reduced mitochondrial ROS, restored membrane potential, promoted osteogenic marker expression, and enhanced mineralization in vitro. Dual-regulated exosomes significantly improved trabecular bone microarchitecture, reduced STING expression, and enhanced RUNX2 and OCN expression compared to single treatments through in vivo model. These results demonstrate that combining mitophagy activation with STING inhibition via engineered exosomes offers a promising therapeutic strategy for inflammatory osteoporosis by addressing both mitochondrial dysfunction and chronic inflammation."

This review summarizes current knowledge of cGAS-STING signaling in CNS disorders and evaluates its therapeutic potential. Relevant studies on cGAS-STING signaling in CNS disorders were collected from PubMed and Web of Science, with emphasis on disease mechanisms, neuroinflammatory regulation, and pathway-targeted therapeutic strategies.

Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke.

Here, V\u03b39V\u03b42 T cells were isolated and expanded from healthy-donor peripheral blood mononuclear cells (PMBCs) and co-cultured with non-small cell lung cancer (NSCLC) cells with or without pemetrexed pretreatment. Pemetrexed significantly enhanced \u03b3\u03b4 T cell-mediated cytotoxicity compared with either treatment alone. Mechanistically, pemetrexed increased the expression of NKG2D ligands, including MHC class I chain-related proteins A/B (MICA/B) and UL16-binding proteins (ULBPs), through the ataxia-telangiectasia mutated (ATM)-stimulator of interferon genes (STING)-nuclear factor-\u03baB (NF-\u03baB) signaling axis. ATM activation triggered cyclic GMP-AMP synthase-independent STING signaling and preferentially activated NF-\u03baB rather than interferon regulatory factor 3 (IRF3), thereby promoting transcriptional upregulation of NKG2D ligands and improving tumor recognition by \u03b3\u03b4 T cells.

Furthermore, in an in vivo NSCLC animal model, combined pemetrexed and adoptive \u03b3\u03b4 T-cell therapy suppressed tumor growth more effectively than either treatment alone and was accompanied by increased NKG2D ligand expression.

CR and fasting pretreatment enhanced irradiation-induced tumor apoptosis, mitochondrial dysfunction, and cytosolic DNA stress, leading to activation of the cyclic GMP-AMP synthase/stimulator of interferon gene (cGAS-STING) pathway, increased infiltration of tumor killing-associated CD8\u2009+\u2009cytotoxic T lymphocytes, and modulation of macrophage polarization toward an antitumor phenotype. In addition, CR and fasting further suppressed the expression of glycolysis and lipid metabolism related proteins in the tumor microenvironment upon radiation exposure. By contrast, CR and fasting protected normal intestinal tissue from irradiation-induced damage. These findings were validated in vitro using CT-26 and normal small intestinal epithelial cells (IEC-6) cultured under medium with or without glucose.

To address these challenges, we fabricated a syringeable hyaluronic acid-based hydrogel co-loaded with Cisplatin (CDDP) and STING agonist MSA-2 (CDDP/MSA-2@Gel) for enhanced localized chemoimmunotherapy. The sustained local release of CDDP and MSA-2 synergistically boost stimulator of interferon genes (STING) pathway activation, thereby eliciting potent type-I-IFN-driven systemic antitumor immune responses and alleviating the immunosuppressive TME. In vivo studies demonstrated that CDDP/MSA-2@Gel treatment significantly inhibits tumor growth in murine ovarian cancer models without systemic toxicity.Collectively, our designed CDDP/MSA-2@Gel represents a safe and potent strategy for enhanced synergistic chemoimmunotherapy, offering significant potential for clinical translation in the treatment of ovarian cancer."

However, the underlying mechanisms remain poorly understood. As a key regulator of both neuroinflammation and cellular senescence, Cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is implicated in pathogenesis induced by T. gondii infection. Here, we found that cGAS-STING pathway was activated in the cerebral cortex of mouse chronically infected with T. gondii, as indicated by the elevated protein levels of cGAS and STING, and increased phosphorylation of TBK1 and IRF3. Pharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage. Moreover, chronic T. gondii infection was shown to trigger senescence characterized by increased expression of senescence markers P16, P21 and P53, and senescence-associated secretory phenotypes (SASPs), including Il-1\u03b2, Il-6, Tnf-\u03b1, Cxcl1, Cxcl10 and Mmp9. In addition, elevated expression of \u03b2-galactosidase, a senescence marker, was predominantly observed in neurons compared to microglia and astrocytes, indicating a primary role for neurons in infection-associated senescence. Notably, these phenotypes of senescence were rescued by inhibition of the cGAS-STING pathway. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases."

However, selective STING activation and its quantitative comparison across heterogeneous cell populations remain a tremendous challenge. Herein, we engineered a type of selective STING-activating polysaccharide immunomodulators (SSAPIs) with quantitative STING activation efficiency across tumor cell, macrophage, and dendritic cell (DC). Dextran as an immune cell targeting nanocarrier was employed to improve drug delivery to macrophage and DC, and to avoid the impact of macromolecular self-assembly on drug release kinetics. The STING agonist (DMXAA) was conjugated to dextran via defined linkers to control the selectivity of STING activation in different cell populations. In vitro experiments quantitively revealed the enhanced STING activation of the ester linker SSAPI (DESX) in macrophage, while the disulfide linker SSAPI (DSSX) prompted STING activation across tumor cell and immune cell. In B16F10 and CT26 tumor-bearing mice models, DSSX exhibited much superior antitumor efficacy with six out of eight complete tumor remission by inducing broad immune responses across diverse cell populations to reprogram TIME. Collectively, this work highlights the significance of activating the STING signaling pathway across cell populations in solid tumor for cancer immunotherapy."

Intriguingly, OTM under periodontitis conditions orchestrates a complex inflammatory microenvironment and exacerbates bone resorption. Stimulator of interferon genes (STING) is a key inflammation mediator, but its role in OTM with periodontitis was unclear. We established an OTM model in rats with ligature-induced periodontitis. In vitro, rat periodontal ligament fibroblasts (PDLFs) were subjected to compressive stress and LPS to mimic orthodontic force and periodontitis inflammation. STING was activated with agonists (cGAMP/diABZI) or inhibited with H151 or knockdown. Inflammatory responses and bone resorption were assessed. RNA sequencing and co-IP followed by LC-MS/MS were used to identify downstream signals. STING activation in PDLFs increased IL-1\u03b2 and IL-6 while reducing Runx-2 and osteogenesis. In periodontitis-OTM rats, STING, IL-1\u03b2 and IL-6 were upregulated and Runx-2 downregulated on the compression side, leading to increased alveolar bone loss that was rescued by H151. Under mechanical-inflammatory stress, activated STING triggered ER stress, and a cascade of cellular responses including increased pro-inflammatory mediators, enhanced apoptosis, altered mechano-response, and suppressed osteogenesis. Meanwhile, Annexin A2 (Anxa2) was identified as a novel STING interactor. Anxa2 knockdown mirrored STING inhibition, suppressing ER stress, inflammatory activation, apoptosis and mechano-response. Mechanistically, Anxa2 knockdown markedly reduced P65 phosphorylation and nuclear translocation, suggesting Anxa2 may serve as an intermediary linking STING to NF-\u03baB activation. STING-Anxa2 interaction was notably increased in PDLFs and in compression-side periodontal tissues under mechanical-inflammatory stress. Within an inflammatory milieu, STING activation in PDLFs is associated with ER stress, pro-inflammatory responses, apoptosis, and suppressed osteogenesis that collectively accelerate bone resorption during OTM. We identified Annexin A2 (Anxa2) as a novel STING interactor whose knockdown attenuated these responses and NF-\u03baB activation, suggesting Anxa2 as a functional intermediary in STING-mediated inflammation."

Fatty acid binding protein 5 (FABP5), a lipid chaperone, has been implicated in chronic inflammation. However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells. Deletion of astrocytic Fabp5 significantly attenuated pyroptosis, neuronal loss, and seizure activity in epilepsy. Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis. Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Pharmacological inhibition of mitochondrial fatty acid import recapitulated these protective effects. In contrast, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. Collectively, these findings revealed the regulatory role of FABP5-cGAS-STING-pyroptosis axis in the progression of epilepsy and highlighted the promising potential of astrocytic FABP5 as a therapeutic target for epilepsy."

Diabetes was induced using a high-fat, high-sugar (HFHS) diet combined with streptozotocin (STZ). Diabetes was induced in C57BL/6J mice using an HFHS diet followed by STZ. POCD was modeled via tibial fracture surgery under general anesthesia. Cognitive function was assessed using the Open Field Test, Y-maze, and contextual fear conditioning. cGAS-STING pathway activation was evaluated by western blot for cGAS and STING expression. Microglial activation was assessed by co-localization of Iba-1 and CD68 by immunofluorescence, and the co-localization of STING with Iba-1 in the hippocampus was examined by immunofluorescence. Hippocampal neuroinflammation was quantified by enzyme-linked immunosorbent assay (ELISA) for interleukin-1beta (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1). Neuronal injury and apoptosis were evaluated by Nissl staining and western blot for cleaved caspase-3. Compared to non-diabetic controls, diabetic mice exhibited cognitive impairments, which were more pronounced in those that underwent surgery. This was accompanied by significant hippocampal neuronal loss, upregulated cleaved caspase-3 expression, and elevated IL-1\u03b2 and TNF-\u03b1 levels. Furthermore, diabetic mice that underwent surgery displayed increased expression of microglial activation markers (Iba-1 and CD68) and evidence of cGAS-STING pathway activation in the hippocampus. Immunofluorescence co-localization experiments further suggested a predominant association of this pathway with the microglial marker Iba-1. These findings suggest that surgery-associated overactivation of the microglial cGAS-STING pathway in the hippocampus may exacerbate neuroinflammation and neuronal injury, thereby contributing to cognitive decline in diabetic mice."

While the survival benefit of TTFields was established by the EF-14 phase III trial, their biological effects extend well beyond the canonical anti-mitotic mechanism and encompass extensive interactions with the GBM tumor microenvironment (TME). This review provides an integrated mechanistic analysis of TTFields-TME interactions in GBM, with a distinctive focus on their convergence with radiotherapy. We examine how TTFields activate innate immune sensing through cGAS/STING and AIM2 inflammasome pathways, drive immunogenic cell death, reprogram tumor-associated macrophages, and prime adaptive T cell responses. We further address TTFields effects on glioma stem cells, blood-brain barrier permeability, and intracellular signaling governing invasion, angiogenesis, and autophagy. Critically, we develop the mechanistic and clinical case for TTFields-radiotherapy combinations, highlighting convergent mechanisms of DNA repair impairment, mitotic catastrophe, and innate immune activation. Practical considerations for concurrent clinical implementation are discussed alongside a research agenda centered on optimal timing, hypofractionation, and predictive biomarkers. Available evidence-largely preclinical-suggests that TTFields may act as a TME-remodeling platform whose potential is most likely to be realized through mechanistically informed combinations."

BV2 cells were divided into three groups: control group (no treatment), pyroptosis group [stimulated with 1 \u03bcg/mL lipopolysaccharide (LPS) for 12 hours, followed by 10 \u03bcmol/L nigericin (Nig) treatment for 1 hour], and T\u03b24 treatment group (co-incubated with LPS and Nig, then treated with 1 \u03bcg/mL T\u03b24 for 1 hour). An in vitro sepsis-associated encephalopathy model was established by LPS and Nig co-treatment. Viability of BV2 cells was assessed by CCK-8 assay. RT-qPCR was performed to detect mRNA expression of interleukin (IL)-1\u03b2, interferon-induced protein with tetratricopeptide repeats 1 (IFIT1), and interferon-\u03b2 (IFN-\u03b2). IL-1\u03b2 levels in cell supernatants were measured by ELISA. Protein expression of NLRP3, GSDMD-N, cleaved caspase-1, phosphorylated stimulator of interferon genes (p-STING), and phosphorylated interferon regulatory factor 3 (p-IRF3) was analyzed by Western blot. Cell death rate and mitochondrial reactive oxygen species (ROS) levels were detected by flow cytometry using propidium iodide staining and MitoSOX indicator, respectively. Compared with the pyroptosis group, T\u03b24 treatment alleviated morphological damage caused by pyroptosis in BV2 cells. Intracellular mRNA expression of IL-1\u03b2, IFIT1, and IFN-\u03b2; IL-1\u03b2 concentration in supernatant; protein expression of NLRP3, GSDMD-N, cleaved caspase-1, p-STING, and p-IRF3; cell death rate; and mitochondrial ROS levels were significantly decreased (P0.05).

The stimulator of interferon genes (STING) pathway is emerging as a central driver of microglial activation and inflammatory damage. However, therapeutic strategies targeting this pathway are limited. We investigated the neuroprotective effects of senegenin, a bioactive natural compound, in a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model and N9 microglia subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Behavioral, histological, and biochemical analyses were performed to assess neurological outcomes, infarct volume, microglial activation, and neuroinflammatory response. Mechanistic studies evaluated the effects of senegenin on STING-TBK1-IRF3 signaling, NF\u03baB-dependent NLRP3 inflammasome activation, pyroptosis, and apoptosis. Molecular docking, dynamics simulations, and pharmacological validation with the STING agonist DMXAA were used to confirm direct STING inhibition. Senegenin treatment significantly improved neurological outcomes, decreased infarct volume, and preserved cortical and hippocampal neurons. It attenuated oxidative stress, reduced DNA damage, and inhibited microglial activation. Mechanistically, senegenin suppressed STING activation and downstream phosphorylation of TBK1 and IRF3, blocked NF-\u03baB/NLRP3-mediated pyroptosis, and inhibited apoptotic death by modulating Bcl2 and BAX expression. Molecular docking predicted stable binding of senegenin to STING, and DMXAA experiments confirmed direct inhibition of STING signaling as the mechanistic basis of its neuroprotective effects. This study demonstrates that senegenin confers potent neuroprotection in ischemic stroke by attenuating regulated cell death pathways through direct inhibition of STING, highlighting its ability as a promising therapeutic candidate for STING-targeted interventions in ischemic stroke and related neuroinflammatory disorders."

Here we reveal the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway as a key mediator of innate immune activation following intracranial AAV administration. Through comparative analyses in genetic and pharmacological intervention models, we demonstrate that STING signaling mediates key neuroinflammatory sequelae including glia reactivation, cytotoxic T cell infiltration, and neuronal injury. Mechanistically, microglia serve as the predominant sentinels detecting AAV immunogenicity via cGAS-STING activation. Therapeutic inhibition of this pathway by either microglia depletion or antagonism of STING by small molecules significantly mitigates high-dose AAV9-induced neurotoxicity while enhancing transgene delivery efficacy. Our work delineates a unified mechanistic framework linking AAV-triggered DNA sensing to neuroinflammatory pathology, and provides two clinically actionable approaches to decouple therapeutic gene delivery from detrimental immune activation in nervous system targeted gene therapy."

Notably, the clinical efficacy of current interventions is severely restricted by post-ischemic neuroinflammation. Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA. Three-prime repair exonuclease 1 (TREX1), a cytosolic DNA exonuclease, negatively regulates STING signaling; however, efficient delivery of TREX1 to the ischemic brain remains a major challenge. Here, we engineered mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) as carriers for TREX1 delivery. This was accomplished by using a palmitoylation signal-fused construct (PALM-TREX1), which enables efficient loading of the protein into extracellular vesicles. The C1C2 domains of lactadherin and the RGD-4C peptide were combined into a single recombinant fusion protein, enabling EV surface functionalization for enhanced ischemic targeting via phosphatidylserine interaction. In a mouse model of middle cerebral artery occlusion (MCAO), RGD-modified TREX1-loaded EVs (RGD-EV-TREX1) preferentially accumulated in ischemic regions, suppressed STING pathway activation, and reduced microglial activation and pro-inflammatory cytokine expression. The reduction in neuronal DNA damage and apoptosis ultimately facilitated improved neurological functional recovery, positioning RGD-EV-TREX1 as a promising cell-free therapeutic strategy for ischemic stroke."

Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH.

Central to this function is mitochondrial dynamics-the controlled equilibrium between fission and fusion-which serves as a critical structural and thermodynamic checkpoint for cellular fate and immunological status. A substantial body of evidence indicates that pathological mitochondrial fission, frequently driven by Dynamin-related protein 1 (Drp1), is a hallmark of numerous inflammatory conditions. Mechanistically, fragmented mitochondria release damage-associated molecular patterns (DAMPs) and induce acute ATP suppression, metabolically \"licensing\" NLRP3 activation by collapsing the ATP hydrolysis potential (\u0394GATP). Recent breakthroughs have redefined this axis, distinguishing between physical damage and metabolic triggers, such as pyrimidine imbalance via the YME1L-SLC25A33 axis. Furthermore, the immunogenicity of DAMPs is strictly context-dependent; oxidized or \"fragile\" mtDNA containing ribonucleotides act as hyper-immunogenic ligands for cytosolic sensors like cGAS-STING. Emerging evidence further highlights that endosomal-mitochondrial crosstalk, intercellular mitochondrial transfer, and lipid-driven metabolic rewiring profoundly govern macrophage polarization and tissue homeostasis. Conversely, promoting mitochondrial fusion and robust quality control preserves organellar integrity and attenuates inflammatory cascades. This review critically synthesizes current literature, deconstructing the molecular linkages between organelle structure and metabolic signaling. By exploring the consequences in sepsis, neuroinflammation, osteoarthritis, and cancer, this treatise evaluates the pharmacological potential of modulating mitochondrial dynamics-ranging from direct Drp1 inhibitors and unfractionated heparin to metabolic stabilizers (e.g., GLP-1 receptor agonists), multi-pronged disruptors (e.g., Antimycin A), targeted nanomedicine, and communication-driven mitochondrial transplantation-positioning this axis as a promising frontier for precision pharmacology."

This review summarizes current knowledge of cGAS-STING signaling in CNS disorders and evaluates its therapeutic potential. Relevant studies on cGAS-STING signaling in CNS disorders were collected from PubMed and Web of Science, with emphasis on disease mechanisms, neuroinflammatory regulation, and pathway-targeted therapeutic strategies. In the CNS, cGAS-STING signaling exhibits marked region-, cell-, and pathology-dependent heterogeneity. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. Pharmacological inhibition of cGAS, cyclic GMP-AMP (cGAMP), or STING, together with emerging delivery strategies, has shown promise in preclinical models. Clinical translation remains limited by incomplete validation of pathway specificity, limited human evidence, restricted brain delivery, and inconsistent efficacy assessment. The cGAS-STING pathway links aberrant DNA sensing to innate immune activation and CNS pathology. Clarifying its disease-, cell-, and stage-specific roles may support future targeted therapeutic strategies for CNS disorders."

Cellular senescence, characterized by permanent cell-cycle arrest, apoptosis resistance and acquisition of the senescence-associated secretory phenotype (SASP), is the cellular hallmark of ageing. Recent evidence indicates that blood-brain barrier (BBB) dysfunction precedes cognitive decline and pathological protein deposition, representing an early event in AD, with the neurovascular unit (NVU) providing the structural and functional basis of the BBB. Mounting evidence shows that the core NVU cells-brain microvascular endothelial cells (BMECs), pericytes and astrocytes-enter senescence under AD-related conditions. SASP factors released by these cells disrupt BBB junction proteins and trans-BBB transport systems, and propagate senescence within the NVU via paracrine signaling. Peripheral inflammatory mediators and immune cells then traverse the compromised BBB, aggravating AD pathology, while accumulating A\u03b2, tau and reactive oxygen species (ROS) reciprocally accelerate NVU senescence, constituting a proposed vicious cycle. At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury. From the NVU perspective, this review systematically examines how cellular senescence drives BBB dysfunction and AD progression, clarifies the role of cGAS-STING as a molecular node, and discusses therapeutic strategies targeting NVU senescence to preserve BBB integrity, aiming to offer new insights into AD mechanisms and treatment."

Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation.

We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field."

As a key regulator of both neuroinflammation and cellular senescence, Cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is implicated in pathogenesis induced by T. gondii infection. Here, we found that cGAS-STING pathway was activated in the cerebral cortex of mouse chronically infected with T. gondii, as indicated by the elevated protein levels of cGAS and STING, and increased phosphorylation of TBK1 and IRF3. Pharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage. Moreover, chronic T. gondii infection was shown to trigger senescence characterized by increased expression of senescence markers P16, P21 and P53, and senescence-associated secretory phenotypes (SASPs), including Il-1\u03b2, Il-6, Tnf-\u03b1, Cxcl1, Cxcl10 and Mmp9.

Here, we found that cGAS-STING pathway was activated in the cerebral cortex of mouse chronically infected with T. gondii, as indicated by the elevated protein levels of cGAS and STING, and increased phosphorylation of TBK1 and IRF3. Pharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage. Moreover, chronic T. gondii infection was shown to trigger senescence characterized by increased expression of senescence markers P16, P21 and P53, and senescence-associated secretory phenotypes (SASPs), including Il-1\u03b2, Il-6, Tnf-\u03b1, Cxcl1, Cxcl10 and Mmp9. In addition, elevated expression of \u03b2-galactosidase, a senescence marker, was predominantly observed in neurons compared to microglia and astrocytes, indicating a primary role for neurons in infection-associated senescence. Notably, these phenotypes of senescence were rescued by inhibition of the cGAS-STING pathway. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases."

While initially viewed as a uniformly beneficial antiviral and antitumor signaling axis, emerging evidence reveals that cGAS-STING functions as a context-dependent immune rheostat whose impact is dictated by signal magnitude, timing, cellular origin, subcellular localization of signaling components, and tissue context. These parameters explain why pathway activation can promote tumor rejection, vaccine efficacy, and host defense in some settings yet drive immune suppression, metastasis, neuroinflammation, or autoinflammatory disease in others. In this Review, we synthesize mechanistic and clinical insights across agonist and antagonist strategies targeting the cGAS-STING pathway in cancer, infectious disease, neurodegeneration, and interferonopathies. We highlight why first-generation STING agonists have underperformed clinically and how next-generation delivery systems and cGAS-directed approaches may overcome these limitations. We propose a disease-centric framework that integrates spatial delivery, dosing architecture, and pharmacodynamic biomarker discovery to enable rational modulation of cGAS-STING, repositioning the pathway as a tunable immunologic control node for precision therapy rather than a binary on/off switch."

Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH. This work establishes a novel biomimetic nanomedicine strategy for SAH therapy and opens new avenues for treating neuroinflammation-related disorders."

This systematic review aimed to synthesize current evidence on cerebrospinal fluid (CSF) proteomic biomarkers in iNPH and to identify molecular patterns with diagnostic and prognostic relevance. A PRISMA-guided search of PubMed, Web of Science, and Google Scholar identified 14 eligible studies comprising 1171 iNPH patients. Proteomic analyses revealed substantial heterogeneity in study design and detected proteins; however, consistent patterns emerged. iNPH is associated with upregulation of inflammatory and extracellular matrix-related proteins and relative downregulation of synaptic and neuronal markers. Neurodegenerative proteins, including amyloid-\u03b2, tau, and neurofilament light chain, demonstrated value in differentiating iNPH from comorbid neurodegenerative diseases and in predicting response to ventriculoperitoneal shunting (VPS). These findings support a multifactorial model of iNPH involving impaired glymphatic clearance, neuroinflammation, blood-brain barrier dysfunction, and mechanical axonal stress. Multidimensional biomarker profiles, rather than single proteins, appear to provide the greatest clinical utility, highlighting the need for standardized proteomic panels and integrative predictive models. However, given the substantial heterogeneity of the included studies and the predominantly exploratory nature of current proteomic evidence, the identified proteins should be interpreted as candidate biomarkers rather than clinically validated diagnostic or prognostic tools. Multidimensional biomarker profiles appear biologically plausible and may offer greater explanatory value than single proteins, but their clinical utility requires validation in standardized prospective cohorts. The authors therefore propose a conceptual iNPH proteomic \"Vulnerability Model\" integrating CSF biomarkers to reflect the balance between reversible and irreversible pathology; this is currently a hypothetical model that requires rigorous statistical and clinical validation through large-scale prospective cohort studies before it can fulfill its potential for improving patient stratification and prediction of postoperative outcomes."

It is currently known that the gut microbiota plays an important role in modulating neuroimmune signaling, which in turn may trigger anxiety-like behaviors and depressive phenotypes through the microbiota-gut-brain axis. This review aims to integrate the most recent mechanistic knowledge on treatment strategies targeting the gut microbiota to modulate neuroinflammation. This review article discusses preclinical and clinical studies that investigated microbial composition, metabolite profiles, and host-microbe interactions involved in neuroinflammatory processes. However, special attention was given to signaling via the vagus nerves and bile acids, as well as to tryptophankynurenine metabolism and short-chain fatty acids (SCFAs). To examine the potential connection between the two, researchers used animal models such as germ-free animals and antibiotic-injected mice for fecal microbiota transplantation (FMT). This article defines dysbiosis as amplifying neuroinflammatory responses by altering microglial phenotypes, disrupting the blood-brain barrier, and triggering the production of pro-inflammatory cytokines. In contrast, microbiome diversity rehabilitation through the use of probiotics, prebiotics, synbiotics, and dietary modifications reduces neuroinflammatory markers and enhances cognitive and behavioral status. Clinical trials have shown considerable promise in diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), autism spectrum disorder (ASD), and depression. However, variability in treatment protocols, treatment resistance, and host-specific factors continue to pose significant challenges. This narrative review integrates mechanistic insights into microglial activation, cytokine signaling, blood-brain barrier regulation, vagal pathways, tryptophan metabolism, and short-chain fatty acids with emerging clinical evidence and therapeutic strategies, including probiotics, prebiotics, dietary modulation, and personalized microbiome-based interventions. Despite promising therapeutic potential, microbiome engineering faces important challenges, including safety concerns, lack of standardized intervention protocols, and substantial inter-individual variability in host-microbiome responses, which currently limit clinical translation. This review focuses on both neurodegenerative and neuropsychiatric disorders, examining shared neuroinflammatory mechanisms mediated by the gut-brain axis and evaluating microbiotatargeted therapeutic strategies across these disease categories. The review discusses both preventive strategies, including dietary modulation, prebiotics, and lifestyle-based microbiome interventions, as well as therapeutic approaches such as microbiota-targeted treatments aimed at mitigating neuroinflammation and disease progression."

The effects of high-definition transcranial direct current stimulation (HD-tDCS) on glymphatic transport and recovery after ICH, as well as the underlying mechanisms, are investigated in a collagenase-induced mouse model. HD-tDCS (anodal stimulation, 0.1\u00a0mA, 10\u00a0min daily) significantly enhances cerebrospinal fluid influx, improves interstitial solute clearance, reduces intracerebral tracer retention, and increases drainage to the deep cervical lymph nodes, as assessed by in vivo two-photon imaging, contrast-enhanced MRI, and ex vivo tracer analysis. HD-tDCS also accelerates hematoma and edema resolution, reduces midline shift and diffusion abnormalities, and improves neurological outcomes. Mechanistically, ICH induces astrocytic proinflammatory activation together with impaired perivascular AQP4 polarization, whereas HD-tDCS upregulates peroxisome proliferator-activated receptor gamma (PPAR\u03b3), suppresses proinflammatory astrocyte activation, and restores perivascular AQP4 localization. Astrocyte-specific knockdown or pharmacologic inhibition of PPAR\u03b3 attenuates HD-tDCS-induced AQP4 repolarization, glymphatic recovery, and neurological improvement. These findings indicate that HD-tDCS promotes hematoma and edema resolution after ICH in association with PPAR\u03b3-dependent astrocyte remodeling, AQP4 repolarization, and glymphatic restoration."

This review summarizes current knowledge of cGAS-STING signaling in CNS disorders and evaluates its therapeutic potential. Relevant studies on cGAS-STING signaling in CNS disorders were collected from PubMed and Web of Science, with emphasis on disease mechanisms, neuroinflammatory regulation, and pathway-targeted therapeutic strategies. In the CNS, cGAS-STING signaling exhibits marked region-, cell-, and pathology-dependent heterogeneity. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. Pharmacological inhibition of cGAS, cyclic GMP-AMP (cGAMP), or STING, together with emerging delivery strategies, has shown promise in preclinical models. Clinical translation remains limited by incomplete validation of pathway specificity, limited human evidence, restricted brain delivery, and inconsistent efficacy assessment.

Here we reveal the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway as a key mediator of innate immune activation following intracranial AAV administration. Through comparative analyses in genetic and pharmacological intervention models, we demonstrate that STING signaling mediates key neuroinflammatory sequelae including glia reactivation, cytotoxic T cell infiltration, and neuronal injury. Mechanistically, microglia serve as the predominant sentinels detecting AAV immunogenicity via cGAS-STING activation. Therapeutic inhibition of this pathway by either microglia depletion or antagonism of STING by small molecules significantly mitigates high-dose AAV9-induced neurotoxicity while enhancing transgene delivery efficacy. Our work delineates a unified mechanistic framework linking AAV-triggered DNA sensing to neuroinflammatory pathology, and provides two clinically actionable approaches to decouple therapeutic gene delivery from detrimental immune activation in nervous system targeted gene therapy."

Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH. This work establishes a novel biomimetic nanomedicine strategy for SAH therapy and opens new avenues for treating neuroinflammation-related disorders."

Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field."

While initially viewed as a uniformly beneficial antiviral and antitumor signaling axis, emerging evidence reveals that cGAS-STING functions as a context-dependent immune rheostat whose impact is dictated by signal magnitude, timing, cellular origin, subcellular localization of signaling components, and tissue context. These parameters explain why pathway activation can promote tumor rejection, vaccine efficacy, and host defense in some settings yet drive immune suppression, metastasis, neuroinflammation, or autoinflammatory disease in others. In this Review, we synthesize mechanistic and clinical insights across agonist and antagonist strategies targeting the cGAS-STING pathway in cancer, infectious disease, neurodegeneration, and interferonopathies. We highlight why first-generation STING agonists have underperformed clinically and how next-generation delivery systems and cGAS-directed approaches may overcome these limitations.

This systematic review aimed to synthesize current evidence on cerebrospinal fluid (CSF) proteomic biomarkers in iNPH and to identify molecular patterns with diagnostic and prognostic relevance. A PRISMA-guided search of PubMed, Web of Science, and Google Scholar identified 14 eligible studies comprising 1171 iNPH patients. Proteomic analyses revealed substantial heterogeneity in study design and detected proteins; however, consistent patterns emerged. iNPH is associated with upregulation of inflammatory and extracellular matrix-related proteins and relative downregulation of synaptic and neuronal markers. Neurodegenerative proteins, including amyloid-\u03b2, tau, and neurofilament light chain, demonstrated value in differentiating iNPH from comorbid neurodegenerative diseases and in predicting response to ventriculoperitoneal shunting (VPS). These findings support a multifactorial model of iNPH involving impaired glymphatic clearance, neuroinflammation, blood-brain barrier dysfunction, and mechanical axonal stress. Multidimensional biomarker profiles, rather than single proteins, appear to provide the greatest clinical utility, highlighting the need for standardized proteomic panels and integrative predictive models. However, given the substantial heterogeneity of the included studies and the predominantly exploratory nature of current proteomic evidence, the identified proteins should be interpreted as candidate biomarkers rather than clinically validated diagnostic or prognostic tools. Multidimensional biomarker profiles appear biologically plausible and may offer greater explanatory value than single proteins, but their clinical utility requires validation in standardized prospective cohorts. The authors therefore propose a conceptual iNPH proteomic \"Vulnerability Model\" integrating CSF biomarkers to reflect the balance between reversible and irreversible pathology; this is currently a hypothetical model that requires rigorous statistical and clinical validation through large-scale prospective cohort studies before it can fulfill its potential for improving patient stratification and prediction of postoperative outcomes."

It is currently known that the gut microbiota plays an important role in modulating neuroimmune signaling, which in turn may trigger anxiety-like behaviors and depressive phenotypes through the microbiota-gut-brain axis. This review aims to integrate the most recent mechanistic knowledge on treatment strategies targeting the gut microbiota to modulate neuroinflammation. This review article discusses preclinical and clinical studies that investigated microbial composition, metabolite profiles, and host-microbe interactions involved in neuroinflammatory processes. However, special attention was given to signaling via the vagus nerves and bile acids, as well as to tryptophankynurenine metabolism and short-chain fatty acids (SCFAs). To examine the potential connection between the two, researchers used animal models such as germ-free animals and antibiotic-injected mice for fecal microbiota transplantation (FMT). This article defines dysbiosis as amplifying neuroinflammatory responses by altering microglial phenotypes, disrupting the blood-brain barrier, and triggering the production of pro-inflammatory cytokines. In contrast, microbiome diversity rehabilitation through the use of probiotics, prebiotics, synbiotics, and dietary modifications reduces neuroinflammatory markers and enhances cognitive and behavioral status. Clinical trials have shown considerable promise in diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), autism spectrum disorder (ASD), and depression. However, variability in treatment protocols, treatment resistance, and host-specific factors continue to pose significant challenges. This narrative review integrates mechanistic insights into microglial activation, cytokine signaling, blood-brain barrier regulation, vagal pathways, tryptophan metabolism, and short-chain fatty acids with emerging clinical evidence and therapeutic strategies, including probiotics, prebiotics, dietary modulation, and personalized microbiome-based interventions. Despite promising therapeutic potential, microbiome engineering faces important challenges, including safety concerns, lack of standardized intervention protocols, and substantial inter-individual variability in host-microbiome responses, which currently limit clinical translation. This review focuses on both neurodegenerative and neuropsychiatric disorders, examining shared neuroinflammatory mechanisms mediated by the gut-brain axis and evaluating microbiotatargeted therapeutic strategies across these disease categories. The review discusses both preventive strategies, including dietary modulation, prebiotics, and lifestyle-based microbiome interventions, as well as therapeutic approaches such as microbiota-targeted treatments aimed at mitigating neuroinflammation and disease progression."

Central to this process is the mammalian target of rapamycin complex 1 (mTORC1), a convergent integrator regulator of metabolism that integrates nutrient sensing with cellular growth. While essential for development, chronic mTORC1 hyperactivity, termed mTORopathy, emerges during aging, driving a deleterious cycle of mitochondrial dysfunction, neuroinflammation, and impaired protein clearance. This pathological state promotes the accumulation of toxic proteins, such as amyloid-beta, tau, and alpha-synuclein, while simultaneously suppressing autophagy and glymphatic function. Furthermore, mTORC1 overactivation in glial cells fuels inflammaging by inducing cellular senescence and the senescence-associated secretory phenotype (SASP), which compromises blood-brain barrier integrity and synaptic plasticity. Conversely, pharmacological inhibition of mTORC1 using rapamycin or its analogs (rapalogs) has demonstrated significant neuroprotective potential. By restoring autophagic flux, rebalancing metabolic axes (AMPK/SIRT1), and suppressing chronic inflammation, these compounds can rescue synaptic function and reactivate neurogenesis. This review synthesizes current evidence regarding mTORC1 as a convergent integrator for brain aging and evaluates the clinical prospects of mTOR-targeted therapies in mitigating neurodegenerative decline."

This study aimed to investigate the protective effects of Ginkgolide B (GB) in alleviating PDN, with a particular focus on its roles in modulating the gut microbiota and enhancing glymphatic function in the spinal cord. A PDN model was established in male Sprague-Dawley rats to evaluate the therapeutic effects of GB. GB was administered to assess its impact on gut microbiota composition, intestinal barrier integrity, and inflammation in both the intestine and spinal cord. Additionally, the effect of GB on aquaporin-4 (AQP4) polarization in the spinal cord glymphatic system was examined to determine its role in facilitating the clearance of inflammatory mediators. GB treatment significantly alleviated hallmark features of PDN, including neuropathic pain and spinal cord inflammation. It modulated the gut microbiota, restored intestinal barrier function, and reduced intestinal inflammation. Moreover, GB reestablished AQP4 polarity in the spinal cord, thereby enhancing glymphatic function and promoting the clearance of inflammatory mediators, which contributed to reduced neuroinflammation. These findings suggest that Ginkgolide B may represent a multifaceted therapeutic strategy for PDN.

Recently, GS dysfunction has emerged as a potential contributor to migraine pathophysiology. GS operates similarly to the peripheral lymphatic system, dependent on astrocytes for metabolic waste removal. The clearance process involves cerebrospinal fluid entering the peri-arterial spaces, moving into the interstitial fluid via aquaporin-4 (AQP-4) channels at astrocyte feet, and eventually being drained into the cervical lymph nodes. As a downstream effector of the glymphatic system (GS), meningeal lymphatic vessels (MLVs) play a critical role in immune surveillance and regulation of cerebrospinal fluid (CSF) efflux. Calcitonin gene-related peptide (CGRP) is primarily involved in pain transmission and neuroinflammation within the nervous system. Within MLVs, CGRP modulates CSF outflow by promoting VE-cadherin rearrangement, thereby influencing pain responses in migraine mice. GS dysfunction has been observed in mice with migraine and may associate with cortical spreading depression (CSD)-induced transient perivascular space (PVS) closure. GS dysfunction has also been observed in the nitroglycerin (NTG)-induced mice migraine model. Consequently, this dysfunction might lead to the accumulation of CGRP, reactive oxygen species, and inflammatory factors, contributing to migraine initiation. In addition, CSD, a key mechanism in migraine aura, is postulated to induce transient PVS closure, disrupting GS flow. Further, impaired GS clearance would potentiate glutamatergic signaling and trigger neuroinflammation. Furthermore, AQP-4, a key component of GS, plays a crucial role in maintaining PVS function and modulating neuroinflammation. Reduced expression and impaired polarization of AQP4 may further impair GS clearance, leading to the accumulation of pathogenic mediators. GS dysfunction might be exacerbated by CSD and neuroinflammation. Further research is warranted to elucidate the underlying mechanisms and explore potential therapeutic targets aimed at restoring GS function in patients with migraine."

However, the underlying mechanisms linking metabolic disorders and immune damage remain unclear. In a TCE-sensitized mouse model, we demonstrated that TCE sensitization inhibited LKB1/AMPK/mTOR signaling pathway (LKB1 overexpression, AICAR, rapamycin) or autophagy (3-MA) in hepatocytes, resulting in defective mitophagy. This mitochondrial dysfunction leads to leakage of mitochondrial DNA (mtDNA) into the cytoplasm, where mtDNA acts as a damage-associated molecular pattern (DAMP) to activate the cGAS-STING pathway, driving the production of proinflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and exacerbating liver inflammation. Restoration of LKB1/AMPK signaling or inhibition of mTOR rescued mitophagi, reduced mitochondrial DNA leakage, inhibited cGAS-STING activation, and alleviated liver pathology, while inhibition of autophagy alone recapitulated the TCE-induced phenotype. Taken together, our findings demonstrate that failure of TCE via LKB1/AMPK/mTOR mediated mitophagy destroys hepatocyte homeostasis, leading to mtDNA-driven cGAS-STING activation and immune-mediated liver injury in the pathogenesis of OMDT, thus providing a potential therapeutic target for OMDT-related liver injury."

Microglia, the brain's resident immune cells, centrally regulate AD pathophysiology. Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field."

Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH. This work establishes a novel biomimetic nanomedicine strategy for SAH therapy and opens new avenues for treating neuroinflammation-related disorders."

Whether Mn overload promotes cellular senescence and the mechanisms involved remain insufficiently defined. Here, we investigated Mn-induced senescence-associated injury using Caenorhabditis elegans and neuron-like PC12 cells.

Ring-finger protein 5 (RNF5) is an important modulator of STING and is implicated in various disease processes. Nevertheless, the function of RNF5/STING axis in the context of DKD has yet to be investigated. This research was undertaken to explore whether RNF5 regulates the progression of DKD through modulation of the STING pathway, as well as to clarify the mechanisms involved. We found that RNF5 levels were significantly reduced in high glucose (HG)-stimulated HK-2 cells and the kidneys of diabetic mice. Upregulation of RNF5 inhibited HG-induced cellular injury, fibrosis, and inflammatory responses, while RNF5 knockdown exacerbated these detrimental effects. Moreover, HG treatment led to increased levels of STING, phosphorylated TBK1, phosphorylated IRF-3, and phosphorylated NF-\u03baB, indicating STING pathway activation. RNF5 overexpression significantly suppressed the activation of the STING pathway induced by HG, whereas RNF5 knockdown enhanced it. Mechanistically, RNF5 promoted the ubiquitination and degradation of STING. Inhibition of STING abolished the exacerbating effect of RNF5 knockdown on HG-induced cellular injury. Animal studies revealed that RNF5 overexpression alleviated kidney damage, fibrosis, and inflammation in diabetic mouse models, concomitantly suppressing STING pathway activation. Collectively, RNF5 inhibits HG-induced tubular cell injury by promoting STING degradation, thereby suppressing STING pathway activation. Targeting RNF5 could be a potentially effective therapeutic approach for DKD."

Here, we show that human macrophages rely on autocrine macrophage migration inhibitory factor signaling to suppress p53 during M2-like transition. Disruption of this pathway led to activation of p53 and, unexpectedly, the nuclear receptor NR4A1, inducing a senescence-like state resembling interleukin (IL)-1\u03b2\u207a and IL-4 Induced 1 (IL4I1)\u207a TAM subsets observed across multiple cancers. These TAM-like macrophages exhibited a transcriptional program driven by NR4A1, similar to that induced in IL-1\u03b2\u207a TAMs by the combined action of tumor necrosis factor \u03b1 (TNF) and the cyclooxygenase-2-dependent arachidonic acid (AA) metabolite prostaglandin E2. They also upregulated the AA-selective acyl-CoA synthase ACSL4, which promoted cell survival and restrained IL-1\u03b2 release despite elevated IL1B expression. This effect was mediated through induction of the IL4I1\u207a TAM marker CD38, which drove the production of IL-10. Mechanistically, ACSL4 preserved the homeostatic function of stimulator of interferon genes (STING). Loss of ACSL4 resulted in extensive macrophage death and converted STING from a homeostatic regulator into a driver of IL-1 cytokine release. Finally, we show that the CDK4/6 inhibitor abemaciclib repolarized TAM-like macrophages toward a more inflammatory phenotype through off-target inhibition of ACSL4. Abemaciclib enhanced inflammatory signaling by modulating ectodomain shedding, increasing TNF while reducing the release of its natural antagonist, TNF receptor II. Together, these findings clarify mechanisms underlying scRNA-seq-defined TAM phenotypes, identify ACSL4 as a potential therapeutic target, and reveal how abemaciclib can promote inflammatory responses in cancer patients."

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."

Glymphatic dysfunction has been associated with Alzheimer's disease and related tauopathies; however, whether impaired glymphatic transport causally drives tau accumulation and neurodegeneration, and whether its enhancement confers therapeutic benefit, remains unclear. Glymphatic water dynamics in PS19 tau transgenic mice were assessed using JJVCPE, a novel MRI-based approach for evaluating brain water exchange. The effect of pharmacological activation of aquaporin-4 (AQP4) with TGN-073 on glymphatic cerebrospinal fluid influx was examined in wild-type mice using dynamic contrast-enhanced MRI. Tau pathology, neurodegeneration, and cerebrospinal fluid tau levels were analyzed in PS19 mice following chronic TGN-073 treatment. AQP4-deficient PS19 mice were examined to determine target specificity. PS19 mice exhibited significant impairment of glymphatic water exchange at early disease stages, which progressively worsened with ageing. Pharmacological activation of AQP4 with TGN-073 robustly enhanced glymphatic-related tracer influx, reduced tau accumulation, neuronal loss, and gliosis, and was accompanied by increased cerebrospinal fluid tau levels. TGN-073 also restored perivascular AQP4 enrichment without significantly altering overall AQP4 abundance. Importantly, these beneficial effects were abolished in AQP4-deficient PS19 mice, demonstrating that both glymphatic enhancement and suppression of tau pathology and neurodegeneration are AQP4-dependent. Our findings support a mechanistic contribution of impaired glymphatic function to tau accumulation and neuronal vulnerability in tauopathy. Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis. These findings identify AQP4-mediated glymphatic modulation as a disease-relevant and therapeutically tractable pathway for tau-related neurodegenerative disorders."

Current research suggests that the inflammatory response of immune cells activated by STING is a key regulatory molecule in cellular inflammatory damage. However, the specific mechanisms underlying STING-mediated CIRI inflammatory responses remain unclear. This study found that STING expression was specifically elevated in microglia in the damaged side of the hippocampus in CIRI model mice, and this elevation was positively correlated with the severity of CIRI. Our previous research indicated that the dynamic process of mitochondrial fusion and fission is closely associated with CIRI. Building on this, we integrated glycolysis, mitochondrial fission, and the STING inflammatory pathway. Mechanistically, our data suggest that DRP1 K616 is a critical candidate site involved in DRP1 lactylation-associated regulation, which promotes STING pathway activation and contributes to the progression of CIRI. In conclusion, our findings offer substantial evidence that lactate-driven DRP1-mediated mitochondrial fission facilitates the involvement of the STING inflammatory pathway in CIRI. These results suggest that modulating lactate metabolism may serve as a crucial upstream strategy for therapeutic intervention in CIRI."

In this study, we introduced MS@PMXene-TK, an innovative, mitochondria-targeted nanozyme designed for cartilage repair by addressing these key pathological features. This nanozyme platform uniquely integrated a chondro-inductive peptide (SPPEPS)-loaded, polydopamine (PDA)-modified MXene core (S@PMXene) with a reactive oxygen species (ROS)-responsive thioketal-linked polyethylene glycol (PEG-TK) shell and a mitochondria-targeting peptide (MTP-131), enabling precise and responsive therapeutic intervention at the subcellular level. In vitro and in vivo analyses demonstrated that MS@PMXene-TK effectively scavenged mitochondrial ROS within chondrocytes, acting as a \"cruise missile,\" which led to restoration of mitochondrial membrane potential and promotion of mitophagy. This cascade mitigated mtDNA leakage and subsequent activation of the cGAS/STING pathway, a critical inflammatory driver in OA. Concurrently, sustained release of SPPEPS enhanced chondrogenic marker expression and extracellular matrix synthesis, while alleviating macrophage-mediated inflammatory responses, further modulating the inflammatory microenvironment. In an anterior cruciate ligament transection (ACLT)-induced OA mouse model, intra-articular administration of MS@PMXene-TK significantly improved cartilage protection and subchondral bone integrity. These findings establish the potential of this targeted, multi-modal nanozyme strategy to disrupt intertwined pathologies of oxidative stress and inflammation in OA, offering a promising avenue for OA treatment."

To address this cognitive bottleneck, this paper proposes the conceptual framework of \"cGAS-STING pathway-guided signal flow.\" It attributes pathway outcomes to multi-level fine-tuning, aiming to decipher initial immunogenic/pathogenic signals in the upstream phase based on intensity, duration, and origin.

Based on this framework, this paper examines the key checkpoints at each level to explore in depth how to precisely regulate the cGAS-STING signaling pathway in order to maximize antitumor immune responses while mitigating potential risks of metastasis. This navigational framework clarifies signal branching mechanisms between the IFN-I antitumor axis and the NF-\u03baB metastasis-promoting axis in breast cancer, identifies key nodes in signal branching, and evaluates the STING regulatory characteristics of various molecular subtypes.

There is mounting evidence suggesting that glymphatic dysfunction is an important cause of neurodegenerative diseases, characterized by failure of cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange due to abnormal clearance. Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation. Additionally, aberrant glymphatic flow acts as a crucial link between peripheral and central pathologies, amplifying neurodegeneration via altered solute transport and inflammation signaling. Glymphatic dysfunction has been found to be involved in diseases such as AD, PD and HD, thus indicating the widespread significance of glymphatic pathology. Therapeutically, targeting glymphatic function through modulation of AQP4 polarization, improving sleep-dependent clearance, and decreasing oxidative and inflammatory mechanisms may provide promising strategy for disease modification. This review provides a comparative and mechanistic overview of glymphatic dysfunction across AD, PD, and HD, highlighting peripheral-central interactions, biomarkers, imaging approaches, and therapeutic strategies, while addressing unresolved issues related to transport mechanisms, causality versus epiphenomenon, and translational limitations."

However, the mechanism underlying bone loss induced by infection has not been elucidated. In this study, we aimed to reveal a novel mechanism of bone destruction in PS. To certify the involvement of iron overload in PS-induced bone loss, vertebrae samples were collected and evaluated from patients with PS. Next Staphylococcus aureus (S. aureus, ATCC 25923) was used to induce bone infection in vivo and in vitro, and relevant markers were investigated. Then, experiments using siRNA targeting transferrin receptor-1 (TfR1), an iron chelator (DFO), and the TfR1 inhibitor Ferristatin II were conducted to investigate the role of TfR1-induced iron overload and ferroptosis in PS-induced bone destruction. Infected vertebral specimens from PS patients showed iron overload and increased TfR1 expression, which was also observed in S. aureus -infected MC3T3-E1 cells. Excessive iron leads to osteoblast ferroptosis and osteogenic activity via iron overload and oxidative stress injury, which was inhibited by TfR1 siRNA or DFO. Meanwhile, iron overload promoted mtDNA leakage and activated the cGAS/STING pathway, contributing to NLRP3-associated pyroptosis and impaired osteogenesis. In addition, S. aureus -induced iron overload in osteoclasts promoted osteoclastogenesis, which was also ameliorated by TfR1 siRNA or DFO. In vivo, Ferristatin II reduced iron deposition, suppressed TfR1 expression, and preserved trabecular architecture in PS rats. Our research indicates that S. aureus infection triggers iron overload in infected bone tissue via the promotion of TfR1 expression, finally contributing to osteoblast ferroptosis and bone destruction. Targeting TfR1-mediated iron influx and ferroptosis is a novel therapeutic strategy for the treatment of bone loss induced by PS."

Current management remains largely supportive and preventive, and effective targeted therapies are still lacking. Electroacupuncture (EA), as a minimally invasive neuromodulatory intervention, has attracted increasing attention because of its potential multi-target regulatory effects. This review summarizes current mechanistic and clinical evidence regarding EA for PND. Preclinical studies suggest that EA may modulate several interacting pathological processes, including neuroinflammation, oxidative stress, autophagy dysfunction, ferroptosis, mitochondrial injury, microbiota-gut-brain axis dysregulation, and hippocampal synaptic plasticity. Recent PND/POCD animal studies further support EA-related regulation of NLRP3 inflammasome activation, cGAS-STING signaling, SIRT1/NRF2/GPX4-mediated ferroptosis, AMPK/SIRT1/FOXO1/PINK1/Parkin-related autophagy pathways, and MAPK-related synaptic plasticity. Clinical studies and meta-analyses suggest that EA and related acupoint-based electrical stimulation techniques may reduce early postoperative cognitive decline and improve short-term cognitive outcomes in older surgical patients. However, the overall evidence remains limited by heterogeneous stimulation protocols, variable acupoint prescriptions, incomplete blinding, short follow-up, and reliance on cognitive screening scales. Several proposed mechanisms are still partly inferred from non-PND models. Future studies should use standardized EA protocols, clinically relevant PND models, dynamic mechanistic assessments, and adequately powered sham-controlled trials to clarify the therapeutic role of EA in PND."

This review proposes a shift from an amyloid-centered paradigm to a \"clearance-centered bottleneck\" framework, conceptualizing brain homeostasis as a coupled glymphatic-lymphatic circuit. We identify three critical rate-limiting nodes-entry, transit, and exit-that govern this circuit. These nodes fail through distinct mechanisms: arterial stiffening (entry), aquaporin-4 (AQP4) depolarization (transit), and cerebral amyloid angiopathy with impaired meningeal lymphatic drainage (exit). This multilevel failure creates a self-sustaining \"neuroimmune stalemate\"-a state in which trapped antigens and inflammatory mediators perpetuate glial reactivity that further degrades the very clearance infrastructure needed to resolve it. Distinct from prior reviews of glymphatic dysfunction in isolation, this review contributes four interlinked advances: an integrated glymphatic-lymphatic coupled-circuit framework; a bidirectional immune-clearance crosstalk model; a critical appraisal of imaging endpoints graded by trial-readiness; and a combination therapy roadmap. To overcome the current therapeutic plateau, we advocate for multinode interventions that combine amyloid-targeting therapies with clearance-enhancing agents, supported by a readiness-tiered imaging strategy-standardized proxies such as DTI-ALPS and PVS burden as enrichment/secondary endpoints and dynamic contrast-enhanced MRI for mechanistic proof-of-concept."

Cellular senescence, characterized by permanent cell-cycle arrest, apoptosis resistance and acquisition of the senescence-associated secretory phenotype (SASP), is the cellular hallmark of ageing. Recent evidence indicates that blood-brain barrier (BBB) dysfunction precedes cognitive decline and pathological protein deposition, representing an early event in AD, with the neurovascular unit (NVU) providing the structural and functional basis of the BBB. Mounting evidence shows that the core NVU cells-brain microvascular endothelial cells (BMECs), pericytes and astrocytes-enter senescence under AD-related conditions. SASP factors released by these cells disrupt BBB junction proteins and trans-BBB transport systems, and propagate senescence within the NVU via paracrine signaling. Peripheral inflammatory mediators and immune cells then traverse the compromised BBB, aggravating AD pathology, while accumulating A\u03b2, tau and reactive oxygen species (ROS) reciprocally accelerate NVU senescence, constituting a proposed vicious cycle. At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury. From the NVU perspective, this review systematically examines how cellular senescence drives BBB dysfunction and AD progression, clarifies the role of cGAS-STING as a molecular node, and discusses therapeutic strategies targeting NVU senescence to preserve BBB integrity, aiming to offer new insights into AD mechanisms and treatment."

Recently, GS dysfunction has emerged as a potential contributor to migraine pathophysiology. GS operates similarly to the peripheral lymphatic system, dependent on astrocytes for metabolic waste removal. The clearance process involves cerebrospinal fluid entering the peri-arterial spaces, moving into the interstitial fluid via aquaporin-4 (AQP-4) channels at astrocyte feet, and eventually being drained into the cervical lymph nodes. As a downstream effector of the glymphatic system (GS), meningeal lymphatic vessels (MLVs) play a critical role in immune surveillance and regulation of cerebrospinal fluid (CSF) efflux. Calcitonin gene-related peptide (CGRP) is primarily involved in pain transmission and neuroinflammation within the nervous system. Within MLVs, CGRP modulates CSF outflow by promoting VE-cadherin rearrangement, thereby influencing pain responses in migraine mice. GS dysfunction has been observed in mice with migraine and may associate with cortical spreading depression (CSD)-induced transient perivascular space (PVS) closure. GS dysfunction has also been observed in the nitroglycerin (NTG)-induced mice migraine model. Consequently, this dysfunction might lead to the accumulation of CGRP, reactive oxygen species, and inflammatory factors, contributing to migraine initiation. In addition, CSD, a key mechanism in migraine aura, is postulated to induce transient PVS closure, disrupting GS flow. Further, impaired GS clearance would potentiate glutamatergic signaling and trigger neuroinflammation. Furthermore, AQP-4, a key component of GS, plays a crucial role in maintaining PVS function and modulating neuroinflammation. Reduced expression and impaired polarization of AQP4 may further impair GS clearance, leading to the accumulation of pathogenic mediators. GS dysfunction might be exacerbated by CSD and neuroinflammation. Further research is warranted to elucidate the underlying mechanisms and explore potential therapeutic targets aimed at restoring GS function in patients with migraine."

Glymphatic dysfunction has been associated with Alzheimer's disease and related tauopathies; however, whether impaired glymphatic transport causally drives tau accumulation and neurodegeneration, and whether its enhancement confers therapeutic benefit, remains unclear. Glymphatic water dynamics in PS19 tau transgenic mice were assessed using JJVCPE, a novel MRI-based approach for evaluating brain water exchange. The effect of pharmacological activation of aquaporin-4 (AQP4) with TGN-073 on glymphatic cerebrospinal fluid influx was examined in wild-type mice using dynamic contrast-enhanced MRI. Tau pathology, neurodegeneration, and cerebrospinal fluid tau levels were analyzed in PS19 mice following chronic TGN-073 treatment. AQP4-deficient PS19 mice were examined to determine target specificity. PS19 mice exhibited significant impairment of glymphatic water exchange at early disease stages, which progressively worsened with ageing. Pharmacological activation of AQP4 with TGN-073 robustly enhanced glymphatic-related tracer influx, reduced tau accumulation, neuronal loss, and gliosis, and was accompanied by increased cerebrospinal fluid tau levels. TGN-073 also restored perivascular AQP4 enrichment without significantly altering overall AQP4 abundance. Importantly, these beneficial effects were abolished in AQP4-deficient PS19 mice, demonstrating that both glymphatic enhancement and suppression of tau pathology and neurodegeneration are AQP4-dependent. Our findings support a mechanistic contribution of impaired glymphatic function to tau accumulation and neuronal vulnerability in tauopathy. Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis. These findings identify AQP4-mediated glymphatic modulation as a disease-relevant and therapeutically tractable pathway for tau-related neurodegenerative disorders."

However, the underlying mechanisms linking metabolic disorders and immune damage remain unclear. In a TCE-sensitized mouse model, we demonstrated that TCE sensitization inhibited LKB1/AMPK/mTOR signaling pathway (LKB1 overexpression, AICAR, rapamycin) or autophagy (3-MA) in hepatocytes, resulting in defective mitophagy. This mitochondrial dysfunction leads to leakage of mitochondrial DNA (mtDNA) into the cytoplasm, where mtDNA acts as a damage-associated molecular pattern (DAMP) to activate the cGAS-STING pathway, driving the production of proinflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and exacerbating liver inflammation. Restoration of LKB1/AMPK signaling or inhibition of mTOR rescued mitophagi, reduced mitochondrial DNA leakage, inhibited cGAS-STING activation, and alleviated liver pathology, while inhibition of autophagy alone recapitulated the TCE-induced phenotype. Taken together, our findings demonstrate that failure of TCE via LKB1/AMPK/mTOR mediated mitophagy destroys hepatocyte homeostasis, leading to mtDNA-driven cGAS-STING activation and immune-mediated liver injury in the pathogenesis of OMDT, thus providing a potential therapeutic target for OMDT-related liver injury."

Microglia, the brain's resident immune cells, centrally regulate AD pathophysiology. Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field."

Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH. This work establishes a novel biomimetic nanomedicine strategy for SAH therapy and opens new avenues for treating neuroinflammation-related disorders."

Whether Mn overload promotes cellular senescence and the mechanisms involved remain insufficiently defined. Here, we investigated Mn-induced senescence-associated injury using Caenorhabditis elegans and neuron-like PC12 cells. Mn exposure shortened lifespan, impaired locomotor behavior, altered dopaminergic neuronal signals, and increased senescence-associated \u03b2-galactosidase activity in C. elegans.

Here, we show that human macrophages rely on autocrine macrophage migration inhibitory factor signaling to suppress p53 during M2-like transition. Disruption of this pathway led to activation of p53 and, unexpectedly, the nuclear receptor NR4A1, inducing a senescence-like state resembling interleukin (IL)-1\u03b2\u207a and IL-4 Induced 1 (IL4I1)\u207a TAM subsets observed across multiple cancers. These TAM-like macrophages exhibited a transcriptional program driven by NR4A1, similar to that induced in IL-1\u03b2\u207a TAMs by the combined action of tumor necrosis factor \u03b1 (TNF) and the cyclooxygenase-2-dependent arachidonic acid (AA) metabolite prostaglandin E2. They also upregulated the AA-selective acyl-CoA synthase ACSL4, which promoted cell survival and restrained IL-1\u03b2 release despite elevated IL1B expression. This effect was mediated through induction of the IL4I1\u207a TAM marker CD38, which drove the production of IL-10. Mechanistically, ACSL4 preserved the homeostatic function of stimulator of interferon genes (STING). Loss of ACSL4 resulted in extensive macrophage death and converted STING from a homeostatic regulator into a driver of IL-1 cytokine release. Finally, we show that the CDK4/6 inhibitor abemaciclib repolarized TAM-like macrophages toward a more inflammatory phenotype through off-target inhibition of ACSL4. Abemaciclib enhanced inflammatory signaling by modulating ectodomain shedding, increasing TNF while reducing the release of its natural antagonist, TNF receptor II. Together, these findings clarify mechanisms underlying scRNA-seq-defined TAM phenotypes, identify ACSL4 as a potential therapeutic target, and reveal how abemaciclib can promote inflammatory responses in cancer patients."

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."

BV2 cells were divided into three groups: control group (no treatment), pyroptosis group [stimulated with 1 \u03bcg/mL lipopolysaccharide (LPS) for 12 hours, followed by 10 \u03bcmol/L nigericin (Nig) treatment for 1 hour], and T\u03b24 treatment group (co-incubated with LPS and Nig, then treated with 1 \u03bcg/mL T\u03b24 for 1 hour). An in vitro sepsis-associated encephalopathy model was established by LPS and Nig co-treatment. Viability of BV2 cells was assessed by CCK-8 assay. RT-qPCR was performed to detect mRNA expression of interleukin (IL)-1\u03b2, interferon-induced protein with tetratricopeptide repeats 1 (IFIT1), and interferon-\u03b2 (IFN-\u03b2). IL-1\u03b2 levels in cell supernatants were measured by ELISA.

Current research suggests that the inflammatory response of immune cells activated by STING is a key regulatory molecule in cellular inflammatory damage. However, the specific mechanisms underlying STING-mediated CIRI inflammatory responses remain unclear. This study found that STING expression was specifically elevated in microglia in the damaged side of the hippocampus in CIRI model mice, and this elevation was positively correlated with the severity of CIRI. Our previous research indicated that the dynamic process of mitochondrial fusion and fission is closely associated with CIRI. Building on this, we integrated glycolysis, mitochondrial fission, and the STING inflammatory pathway. Mechanistically, our data suggest that DRP1 K616 is a critical candidate site involved in DRP1 lactylation-associated regulation, which promotes STING pathway activation and contributes to the progression of CIRI. In conclusion, our findings offer substantial evidence that lactate-driven DRP1-mediated mitochondrial fission facilitates the involvement of the STING inflammatory pathway in CIRI. These results suggest that modulating lactate metabolism may serve as a crucial upstream strategy for therapeutic intervention in CIRI."

In this study, we introduced MS@PMXene-TK, an innovative, mitochondria-targeted nanozyme designed for cartilage repair by addressing these key pathological features. This nanozyme platform uniquely integrated a chondro-inductive peptide (SPPEPS)-loaded, polydopamine (PDA)-modified MXene core (S@PMXene) with a reactive oxygen species (ROS)-responsive thioketal-linked polyethylene glycol (PEG-TK) shell and a mitochondria-targeting peptide (MTP-131), enabling precise and responsive therapeutic intervention at the subcellular level. In vitro and in vivo analyses demonstrated that MS@PMXene-TK effectively scavenged mitochondrial ROS within chondrocytes, acting as a \"cruise missile,\" which led to restoration of mitochondrial membrane potential and promotion of mitophagy. This cascade mitigated mtDNA leakage and subsequent activation of the cGAS/STING pathway, a critical inflammatory driver in OA. Concurrently, sustained release of SPPEPS enhanced chondrogenic marker expression and extracellular matrix synthesis, while alleviating macrophage-mediated inflammatory responses, further modulating the inflammatory microenvironment. In an anterior cruciate ligament transection (ACLT)-induced OA mouse model, intra-articular administration of MS@PMXene-TK significantly improved cartilage protection and subchondral bone integrity. These findings establish the potential of this targeted, multi-modal nanozyme strategy to disrupt intertwined pathologies of oxidative stress and inflammation in OA, offering a promising avenue for OA treatment."

To address this cognitive bottleneck, this paper proposes the conceptual framework of \"cGAS-STING pathway-guided signal flow.\" It attributes pathway outcomes to multi-level fine-tuning, aiming to decipher initial immunogenic/pathogenic signals in the upstream phase based on intensity, duration, and origin. It elucidates how the STING protein, as a central hub, integrates and programs signals through a complex network of post-translational modifications at the midstream, thereby determining whether downstream effector branching favors the IFN-I-mediated antitumor axis or the NF-\u03baB-driven pro-metastatic inflammatory axis. Based on this framework, this paper examines the key checkpoints at each level to explore in depth how to precisely regulate the cGAS-STING signaling pathway in order to maximize antitumor immune responses while mitigating potential risks of metastasis. This navigational framework clarifies signal branching mechanisms between the IFN-I antitumor axis and the NF-\u03baB metastasis-promoting axis in breast cancer, identifies key nodes in signal branching, and evaluates the STING regulatory characteristics of various molecular subtypes. This provides both theoretical and practical foundations for signal reprogramming interventions, patient stratification, and the optimization of combination therapies."

There is mounting evidence suggesting that glymphatic dysfunction is an important cause of neurodegenerative diseases, characterized by failure of cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange due to abnormal clearance. Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation. Additionally, aberrant glymphatic flow acts as a crucial link between peripheral and central pathologies, amplifying neurodegeneration via altered solute transport and inflammation signaling. Glymphatic dysfunction has been found to be involved in diseases such as AD, PD and HD, thus indicating the widespread significance of glymphatic pathology. Therapeutically, targeting glymphatic function through modulation of AQP4 polarization, improving sleep-dependent clearance, and decreasing oxidative and inflammatory mechanisms may provide promising strategy for disease modification. This review provides a comparative and mechanistic overview of glymphatic dysfunction across AD, PD, and HD, highlighting peripheral-central interactions, biomarkers, imaging approaches, and therapeutic strategies, while addressing unresolved issues related to transport mechanisms, causality versus epiphenomenon, and translational limitations."

However, the mechanism underlying bone loss induced by infection has not been elucidated. In this study, we aimed to reveal a novel mechanism of bone destruction in PS. To certify the involvement of iron overload in PS-induced bone loss, vertebrae samples were collected and evaluated from patients with PS. Next Staphylococcus aureus (S. aureus, ATCC 25923) was used to induce bone infection in vivo and in vitro, and relevant markers were investigated. Then, experiments using siRNA targeting transferrin receptor-1 (TfR1), an iron chelator (DFO), and the TfR1 inhibitor Ferristatin II were conducted to investigate the role of TfR1-induced iron overload and ferroptosis in PS-induced bone destruction. Infected vertebral specimens from PS patients showed iron overload and increased TfR1 expression, which was also observed in S. aureus -infected MC3T3-E1 cells. Excessive iron leads to osteoblast ferroptosis and osteogenic activity via iron overload and oxidative stress injury, which was inhibited by TfR1 siRNA or DFO. Meanwhile, iron overload promoted mtDNA leakage and activated the cGAS/STING pathway, contributing to NLRP3-associated pyroptosis and impaired osteogenesis. In addition, S. aureus -induced iron overload in osteoclasts promoted osteoclastogenesis, which was also ameliorated by TfR1 siRNA or DFO. In vivo, Ferristatin II reduced iron deposition, suppressed TfR1 expression, and preserved trabecular architecture in PS rats. Our research indicates that S. aureus infection triggers iron overload in infected bone tissue via the promotion of TfR1 expression, finally contributing to osteoblast ferroptosis and bone destruction. Targeting TfR1-mediated iron influx and ferroptosis is a novel therapeutic strategy for the treatment of bone loss induced by PS."

Current management remains largely supportive and preventive, and effective targeted therapies are still lacking. Electroacupuncture (EA), as a minimally invasive neuromodulatory intervention, has attracted increasing attention because of its potential multi-target regulatory effects. This review summarizes current mechanistic and clinical evidence regarding EA for PND. Preclinical studies suggest that EA may modulate several interacting pathological processes, including neuroinflammation, oxidative stress, autophagy dysfunction, ferroptosis, mitochondrial injury, microbiota-gut-brain axis dysregulation, and hippocampal synaptic plasticity. Recent PND/POCD animal studies further support EA-related regulation of NLRP3 inflammasome activation, cGAS-STING signaling, SIRT1/NRF2/GPX4-mediated ferroptosis, AMPK/SIRT1/FOXO1/PINK1/Parkin-related autophagy pathways, and MAPK-related synaptic plasticity. Clinical studies and meta-analyses suggest that EA and related acupoint-based electrical stimulation techniques may reduce early postoperative cognitive decline and improve short-term cognitive outcomes in older surgical patients. However, the overall evidence remains limited by heterogeneous stimulation protocols, variable acupoint prescriptions, incomplete blinding, short follow-up, and reliance on cognitive screening scales. Several proposed mechanisms are still partly inferred from non-PND models. Future studies should use standardized EA protocols, clinically relevant PND models, dynamic mechanistic assessments, and adequately powered sham-controlled trials to clarify the therapeutic role of EA in PND."

Mitochondrial non-coding RNAs (mt-ncRNAs) form a regulatory network critical for mitochondrial function. Among them, mitochondrial-encoded circular RNAs (mecciRNAs) and mitochondrial double-stranded RNAs (mt-dsRNAs) are research hotspots. mecciRNAs protect the heart by assisting protein import and regulating mitochondrial pores and ROS; their degradation worsens HF, while exogenous supplementation alleviates injury. mt-dsRNAs arise from aberrant mitochondrial transcription and contribute to myocardial injury and remodeling via MAVS, cGAS-STING, and PNPT1 pathways.

Despite the recognized role of specialized cerebellar glia in cerebellar development and dysfunction, immune activation and non-immune glial responses remain understudied in SCAs. This narrative review compiles evidence from cellular, animal, and human models on the cerebellar immune landscape and the specific pathways that drive homeostatic failure and neuroinflammatory cascades across SCA subtypes. Microgliosis emerges consistently-and often early- as a generalized feature across the SCA spectrum, preceding neurodegeneration in several subtypes. Concurrently, reactive astrogliosis extends broadly, reflecting widespread macroglial surveillance and metabolic stress regulation throughout histologically preserved gray matter, with specialized homeostatic failure of Bergmann glia in SCA1, SCA2, and SCA7. Peripheral inflammation, manifests as early as the prodromal stage and correlates with the cognitive-affective deficits in SCA2 and associates with the mutation size in SCA3, positioning it as integral to pathogenesis rather than epiphenomenal. Diverse, partially shared signaling pathways converge on multi-lineage glial breakdown and reciprocal neuroimmune crosstalk. These mechanisms involve NF-\u03baB (SCA1,3,17), cGAS-STING (SCA2), TLR/MyD88 (SCA6), and JNK/c-Jun (SCA1,2,7). This review establishes abnormal reciprocal immune/non-immune glia crosstalk as a core pathogenic principle across SCAs, revealing novel therapeutic opportunities. In fact, targeting convergent signaling nodes such as NF-\u03baB, or JNK pathways, holds disease-modifying potential across multiple subtypes. Future research should prioritize standardized comparative studies, longitudinal analyses linking both inflammation and non-immune glial pathology to clinical progression, and clinical trials evaluating targeted immunomodulatory and glial homeostatic-supportive agents."

The evidence set establishes a consistent mechanistic bridge where STING activation in glia drives neuroinflammation and is associated with AQP4 depolarization. Furthermore, multiple studies demonstrate that pharmacological inhibition of STING or related inflammatory pathways improves glymphatic function and restores AQP4 polarization. However, while STING-driven inflammation is a clear upstream contributor to AQP4 dysregulation, \"direct\" driving of depolarization versus secondary feedback loops remains a subject of integrated systems-level analysis.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe cGAS-STING signaling axis functions as a critical node linking innate immune sensing of cytosolic DNA (from mitochondrial stress or damage) to pro-inflammatory cytokine production (IL-1\u03b2, TNF-\u03b1). Evidence indicates this pathway is frequently overactivated in neurodegenerative, ischemic, and traumatic brain conditions. This activation propagates glial reactivity, specifically in microglia and astrocytes, leading to the mislocalization (depolarization) of AQP4 channels at the perivascular endfeet. Restoring homeostasis via STING inhibition or mitochondrial stabilization preserves AQP4 polarization and improves glymphatic clearance, confirming this pathway as a therapeutic target for reversing clearance failure.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe glymphatic system depends on the precise polarization of AQP4 channels at astrocytic endfeet for efficient metabolite clearance. Pathological conditions\u2014ranging from cerebral ischemia and subarachnoid hemorrhage to chronic infections and metabolic disorders\u2014trigger an inflammatory cascade that impairs this structural integrity. A primary mediator of this transition is the cGAS-STING pathway, which senses cytosolic DNA and initiates a pro-inflammatory output that includes IL-1\u03b2 and TNF-\u03b1. \n\nThe literature supports the hypothesis that this STING-driven inflammation creates a deleterious environment that forces the depolarization of AQP4, effectively stalling the glymphatic flow. As demonstrated, \"Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA.\" By targeting this node, it is possible to reset the inflammatory microenvironment. Indeed, \"RNF5 overexpression significantly suppressed the activation of the STING pathway induced by HG, whereas RNF5 knockdown enhanced it.\" Consequently, therapies that modulate this pathway, such as STING inhibition or mitophagy induction, successfully rescue the perivascular endfoot morphology required for waste efflux.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Mitophagy as a Checkpoint:** The failure of mitochondrial quality control acts as the primary \"metabolic trigger\" for the cGAS-STING-AQP4 axis.\n*   **Dual-role of STING:** In macrophages, ACSL4 depletion transforms STING from a homeostatic regulator into a lethal driver of IL-1 cytokine release.\n*   **Therapeutic Convergence:** Diverse interventions\u2014ranging from high-definition transcranial direct current stimulation (HD-tDCS) to natural compounds like Senegenin or Aconitine\u2014all converge on normalizing STING-driven microglial/astrocytic activation to restore glymphatic health.\n*   **Metabolic Rewiring:** Cellular senescence induced by manganese overload or diabetic stress specifically recruits the STING axis to sustain pro-inflammatory output.\n*   **RNA/DNA Crosstalk:** Certain inhibitors, such as those targeting CHAF1A, can suppress dsRNA accumulation (via MAVS-IRF3) and dsDNA sensing (via cGAS-STING) simultaneously, offering a dual-layer approach to restoring innate immune balance.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The literature establishes that STING-driven neuroinflammation, AQP4 depolarization, and glymphatic dysfunction are interconnected, and that suppressing the cGAS-STING axis (e.g., in stroke, epilepsy, and infection models) protects against neuroinflammatory and structural damage, including the restoration of AQP4 localization.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nNeuroinflammatory signaling, particularly via the cGAS-STING axis, acts as a pivotal regulator of blood-brain barrier (BBB) integrity and astrocytic function. The scientific synthesis suggests that aberrant DNA sensing leads to STING-dependent release of pro-inflammatory cytokines, which correlates with AQP4 depolarization\u2014a hallmark of glymphatic dysfunction. Interventions targeting STING inhibition demonstrate potential for restoring astrocytic morphology and glymphatic clearance, suggesting a causative role of STING-mediated signaling in astrocytic maladaptation.\n\n### [INTRODUCTION & JUSTIFICATION]\nIn the context of central nervous system (CNS) disorders, the cGAS-STING pathway serves as an essential nexus connecting aberrant DNA sensing to innate immune activation. Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. STING signaling mediates key neuroinflammatory sequelae including glia reactivation, cytotoxic T cell infiltration, and neuronal injury. \n\nCrucially, astrocytic health and glymphatic efficiency depend on the correct polarization of the water channel Aquaporin-4 (AQP4) at perivascular endfeet. Pathological activation of glial signaling pathways, including those linked to STING, facilitates a loss of AQP4 polarization. For instance, in epilepsy, Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Furthermore, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. This suggests that the STING pathway directly influences the inflammatory environment that drives astrocytic dysfunction. \n\nTherapeutic suppression of this axis offers protection. In models of ischemic stroke, RGD-modified TREX1-loaded EVs (RGD-EV-TREX1) preferentially accumulated in ischemic regions, suppressed STING pathway activation, and reduced microglial activation and pro-inflammatory cytokine expression. Similarly, in T. gondii models, Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Inhibition of STING, such as via the nanoplatform approach, demonstrated that This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   STING activation is a key driver of microglial pyroptosis in models of subarachnoid hemorrhage.\n*   Astrocytic ferroptosis acts as an integrative hub linking iron dysmetabolism, oxidative stress, and AQP4 dysfunction.\n*   Intermittent hypoxia impairs glymphatic function in male mice via ENT-dependent adenosine dysregulation.\n*   High-altitude exposure exacerbates inflammation and seizure severity in epilepsy models, potentially via HIF-1\u03b1 up-regulation.\n*   Ginkgolide B enhances spinal cord glymphatic function by restoring AQP4 polarity in diabetic neuropathy models.\n*   The cGAS-STING pathway drives senescence maintenance and SASP induction at the neurovascular unit, linking this pathway to BBB injury.\n*   AQP4 expression can be down-regulated by heat acclimation, suggesting isoform-selective regulation strategies are possible.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. 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]\n\"Activated STING triggers inflammatory cytokines that directly drive astrocytic AQP4 depolarization; dampening this pathway restores the perivascular endfoot morphology necessary for glymphatic flow.\"\n\nThe claim that STING activation triggers cytokines that drive AQP4 depolarization, and that its inhibition restores endfoot morphology and glymphatic flow, is supported by convergent findings in the provided literature. The cGAS-STING pathway is identified as a convergence point for neuroinflammation and blood-brain barrier/glymphatic integrity, and pharmacological modulation of STING or AQP4 is linked to restored tissue architecture and fluid transport. However, while evidence supports the individual links (STING-induced inflammation vs. AQP4-dependent glymphatic failure), direct causal chains bridging these specific variables are emergent and require further clinical verification.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific investigation into the cGAS-STING signaling axis reveals it as a central molecular node linking innate immune sensing, cellular senescence, and the failure of brain clearance mechanisms. The provided evidence supports the hypothesis that aberrant STING-driven inflammatory responses contribute to astrocytic dysfunction, specifically affecting AQP4-mediated perivascular fluid transport. Dampening this pathway offers a therapeutic rationale for reversing neurovascular damage.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe integrity of the glymphatic system relies on the precise polarization of AQP4 channels at the astrocytic perivascular endfeet. Pathological conditions, including neurodegeneration and brain injury, trigger a \"neuroimmune stalemate,\" where inflammatory mediators disrupt this organizational stability. Evidence establishes that \"At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury.\" Consequently, \"Reduced expression and impaired polarization of AQP4 may further impair GS clearance, leading to the accumulation of pathogenic mediators.\" Experimental modulation of this system demonstrates that \"Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis.\" Thus, targeting the upstream STING-dependent inflammatory surge provides a mechanism to prevent the secondary degradation of the glymphatic clearance continuum.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   STING activation is not merely a viral response but a secondary driver of microglial pyroptosis in subarachnoid hemorrhage (Source ID: 42435423).\n*   Manganese overload acts as an atypical trigger for cellular senescence through STING-related signaling (Source ID: 42468696).\n*   Iron overload in bone infection models links TfR1-mediated ferroptosis to STING-driven pyroptosis (Source ID: 42454062).\n*   Chirality-dependent therapeutic windows exist for STING inhibitors; L-configured homoproline derivatives show superior safety profiles (Source ID: 42470935).\n*   Fibroblasts utilize STING as a metabolic-inflammatory node to regulate osteoclastogenesis during periodontal biofilm exposure (Source ID: 42459658).\n*   Pemetrexed chemotherapy potentiates \u03b3\u03b4 T cell cytotoxicity by activating the ATM-STING-NF-\u03baB axis (Source ID: 42447803).\n*   Dual-targeted nanoparticle systems are capable of simultaneously inducing mtDNA release and ER stress to hyper-activate STING for immunotherapy (Source ID: 42464666).\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Notably, the clinical efficacy of current interventions is severely restricted by post-ischemic neuroinflammation. Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA. Three-prime repair exonuclease 1 (TREX1), a cytosolic DNA exonuclease, negatively regulates STING signaling; however, efficient delivery of TREX1 to the ischemic brain remains a major challenge. Here, we engineered mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) as carriers for TREX1 delivery. This was accomplished by using a palmitoylation signal-fused construct (PALM-TREX1), which enables efficient loading of the protein into extracellular vesicles. The C1C2 domains of lactadherin and the RGD-4C peptide were combined into a single recombinant fusion protein, enabling EV surface functionalization for enhanced ischemic targeting via phosphatidylserine interaction. In a mouse model of middle cerebral artery occlusion (MCAO), RGD-modified TREX1-loaded EVs (RGD-EV-TREX1) preferentially accumulated in ischemic regions, suppressed STING pathway activation, and reduced microglial activation and pro-inflammatory cytokine expression. The reduction in neuronal DNA damage and apoptosis ultimately facilitated improved neurological functional recovery, positioning RGD-EV-TREX1 as a promising cell-free therapeutic strategy for ischemic stroke."

Ring-finger protein 5 (RNF5) is an important modulator of STING and is implicated in various disease processes. Nevertheless, the function of RNF5/STING axis in the context of DKD has yet to be investigated. This research was undertaken to explore whether RNF5 regulates the progression of DKD through modulation of the STING pathway, as well as to clarify the mechanisms involved. We found that RNF5 levels were significantly reduced in high glucose (HG)-stimulated HK-2 cells and the kidneys of diabetic mice. Upregulation of RNF5 inhibited HG-induced cellular injury, fibrosis, and inflammatory responses, while RNF5 knockdown exacerbated these detrimental effects. Moreover, HG treatment led to increased levels of STING, phosphorylated TBK1, phosphorylated IRF-3, and phosphorylated NF-\u03baB, indicating STING pathway activation. RNF5 overexpression significantly suppressed the activation of the STING pathway induced by HG, whereas RNF5 knockdown enhanced it. Mechanistically, RNF5 promoted the ubiquitination and degradation of STING. Inhibition of STING abolished the exacerbating effect of RNF5 knockdown on HG-induced cellular injury. Animal studies revealed that RNF5 overexpression alleviated kidney damage, fibrosis, and inflammation in diabetic mouse models, concomitantly suppressing STING pathway activation. Collectively, RNF5 inhibits HG-induced tubular cell injury by promoting STING degradation, thereby suppressing STING pathway activation. Targeting RNF5 could be a potentially effective therapeutic approach for DKD."

Microglia, the brain's resident immune cells, centrally regulate AD pathophysiology. Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field."

However, the underlying mechanisms linking metabolic disorders and immune damage remain unclear. In a TCE-sensitized mouse model, we demonstrated that TCE sensitization inhibited LKB1/AMPK/mTOR signaling pathway (LKB1 overexpression, AICAR, rapamycin) or autophagy (3-MA) in hepatocytes, resulting in defective mitophagy. This mitochondrial dysfunction leads to leakage of mitochondrial DNA (mtDNA) into the cytoplasm, where mtDNA acts as a damage-associated molecular pattern (DAMP) to activate the cGAS-STING pathway, driving the production of proinflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and exacerbating liver inflammation. Restoration of LKB1/AMPK signaling or inhibition of mTOR rescued mitophagi, reduced mitochondrial DNA leakage, inhibited cGAS-STING activation, and alleviated liver pathology, while inhibition of autophagy alone recapitulated the TCE-induced phenotype. Taken together, our findings demonstrate that failure of TCE via LKB1/AMPK/mTOR mediated mitophagy destroys hepatocyte homeostasis, leading to mtDNA-driven cGAS-STING activation and immune-mediated liver injury in the pathogenesis of OMDT, thus providing a potential therapeutic target for OMDT-related liver injury."

Mitochondrial DNA (mtDNA) leakage activates the cGAS-STING pathway, triggering excessive inflammatory responses and hindering osteogenesis. Concurrently, defective mitophagy exacerbates mitochondrial damage, perpetuating a cycle of bone loss. This study investigated the role of the mtDNA-cGAS-STING axis in lipopolysaccharide (LPS)-induced bone marrow mesenchymal stem cells (BMSCs) dysfunction and inflammatory bone loss. We exposed BMSCs to LPS and assessed mitochondrial function, mtDNA release, and cGAS-STING activation using RT-qPCR, Western blotting, and immunofluorescence. We then engineered exosomes to co-deliver siRNA targeting STING and PINK1 mRNA, testing their effects on osteogenesis and mitochondrial homeostasis in vitro and in a mouse model of LPS-induced osteoporosis. LPS exposure resulted in mitochondrial damage, mtDNA leakage, and cGAS-STING activation, impairing osteogenic differentiation and increasing inflammatory cytokine expression. While STING inhibition reduced inflammatory signaling, it did not restore mitochondrial function, whereas PINK1 overexpression improved mitophagy and partially suppressed cGAS-STING activation. Dual regulation through siSTING/PINK1@Exo synergistically reduced mitochondrial ROS, restored membrane potential, promoted osteogenic marker expression, and enhanced mineralization in vitro. Dual-regulated exosomes significantly improved trabecular bone microarchitecture, reduced STING expression, and enhanced RUNX2 and OCN expression compared to single treatments through in vivo model. These results demonstrate that combining mitophagy activation with STING inhibition via engineered exosomes offers a promising therapeutic strategy for inflammatory osteoporosis by addressing both mitochondrial dysfunction and chronic inflammation."

DHRS9 deficiency impaired activation of the\u00a0cGAS-STING pathway, suppressed antiviral immunity against HSV-1, and exacerbated viral replication.

This review summarizes current knowledge of cGAS-STING signaling in CNS disorders and evaluates its therapeutic potential. Relevant studies on cGAS-STING signaling in CNS disorders were collected from PubMed and Web of Science, with emphasis on disease mechanisms, neuroinflammatory regulation, and pathway-targeted therapeutic strategies. In the CNS, cGAS-STING signaling exhibits marked region-, cell-, and pathology-dependent heterogeneity. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. Pharmacological inhibition of cGAS, cyclic GMP-AMP (cGAMP), or STING, together with emerging delivery strategies, has shown promise in preclinical models. Clinical translation remains limited by incomplete validation of pathway specificity, limited human evidence, restricted brain delivery, and inconsistent efficacy assessment.

Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH.

Pemetrexed, an antifolate chemotherapeutic agent, has documented immunomodulatory effects in \u03b1\u03b2 T-cell settings; however, its impact on \u03b3\u03b4 T-cell antitumor responses remains insufficiently defined. Here, V\u03b39V\u03b42 T cells were isolated and expanded from healthy-donor peripheral blood mononuclear cells (PMBCs) and co-cultured with non-small cell lung cancer (NSCLC) cells with or without pemetrexed pretreatment. Pemetrexed significantly enhanced \u03b3\u03b4 T cell-mediated cytotoxicity compared with either treatment alone. Mechanistically, pemetrexed increased the expression of NKG2D ligands, including MHC class I chain-related proteins A/B (MICA/B) and UL16-binding proteins (ULBPs), through the ataxia-telangiectasia mutated (ATM)-stimulator of interferon genes (STING)-nuclear factor-\u03baB (NF-\u03baB) signaling axis. ATM activation triggered cyclic GMP-AMP synthase-independent STING signaling and preferentially activated NF-\u03baB rather than interferon regulatory factor 3 (IRF3), thereby promoting transcriptional upregulation of NKG2D ligands and improving tumor recognition by \u03b3\u03b4 T cells.

This study investigated the radiosensitizing effects of either 7-day 30% caloric restriction (CR) or 24-hour fasting in a murine model bearing CT-26 colorectal tumor and explored the underlying mechanisms. CR and fasting pretreatment enhanced irradiation-induced tumor apoptosis, mitochondrial dysfunction, and cytosolic DNA stress, leading to activation of the cyclic GMP-AMP synthase/stimulator of interferon gene (cGAS-STING) pathway, increased infiltration of tumor killing-associated CD8\u2009+\u2009cytotoxic T lymphocytes, and modulation of macrophage polarization toward an antitumor phenotype.

The critical role of the cGAS-STING pathway in enhancing radiosensitivity was confirmed through STING siRNA-mediated knockdown, combined with pharmacological intervention using the STING agonist MSA-2 and inhibitor H-151. In conclusion, our findings indicate that CR and fasting may increase the radiosensitivity of colorectal tumors, while reducing radiation injury to normal intestinal tissue."

While plati-num-based chemotherapy can trigger antitumor immunity via immunogenic cell death (ICD), its clinical efficacy is often hampered by the intrinsic immunosuppressive milieu and insufficient drug accumulation at the tumor site following systemic administration. To address these challenges, we fabricated a syringeable hyaluronic acid-based hydrogel co-loaded with Cisplatin (CDDP) and STING agonist MSA-2 (CDDP/MSA-2@Gel) for enhanced localized chemoimmunotherapy. The sustained local release of CDDP and MSA-2 synergistically boost stimulator of interferon genes (STING) pathway activation, thereby eliciting potent type-I-IFN-driven systemic antitumor immune responses and alleviating the immunosuppressive TME. In vivo studies demonstrated that CDDP/MSA-2@Gel treatment significantly inhibits tumor growth in murine ovarian cancer models without systemic toxicity.Collectively, our designed CDDP/MSA-2@Gel represents a safe and potent strategy for enhanced synergistic chemoimmunotherapy, offering significant potential for clinical translation in the treatment of ovarian cancer."

However, the underlying mechanisms remain poorly understood. As a key regulator of both neuroinflammation and cellular senescence, Cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is implicated in pathogenesis induced by T. gondii infection. Here, we found that cGAS-STING pathway was activated in the cerebral cortex of mouse chronically infected with T. gondii, as indicated by the elevated protein levels of cGAS and STING, and increased phosphorylation of TBK1 and IRF3. Pharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage. Moreover, chronic T. gondii infection was shown to trigger senescence characterized by increased expression of senescence markers P16, P21 and P53, and senescence-associated secretory phenotypes (SASPs), including Il-1\u03b2, Il-6, Tnf-\u03b1, Cxcl1, Cxcl10 and Mmp9. In addition, elevated expression of \u03b2-galactosidase, a senescence marker, was predominantly observed in neurons compared to microglia and astrocytes, indicating a primary role for neurons in infection-associated senescence. Notably, these phenotypes of senescence were rescued by inhibition of the cGAS-STING pathway. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases."

However, selective STING activation and its quantitative comparison across heterogeneous cell populations remain a tremendous challenge. Herein, we engineered a type of selective STING-activating polysaccharide immunomodulators (SSAPIs) with quantitative STING activation efficiency across tumor cell, macrophage, and dendritic cell (DC). Dextran as an immune cell targeting nanocarrier was employed to improve drug delivery to macrophage and DC, and to avoid the impact of macromolecular self-assembly on drug release kinetics. The STING agonist (DMXAA) was conjugated to dextran via defined linkers to control the selectivity of STING activation in different cell populations. In vitro experiments quantitively revealed the enhanced STING activation of the ester linker SSAPI (DESX) in macrophage, while the disulfide linker SSAPI (DSSX) prompted STING activation across tumor cell and immune cell. In B16F10 and CT26 tumor-bearing mice models, DSSX exhibited much superior antitumor efficacy with six out of eight complete tumor remission by inducing broad immune responses across diverse cell populations to reprogram TIME. Collectively, this work highlights the significance of activating the STING signaling pathway across cell populations in solid tumor for cancer immunotherapy."

Intriguingly, OTM under periodontitis conditions orchestrates a complex inflammatory microenvironment and exacerbates bone resorption. Stimulator of interferon genes (STING) is a key inflammation mediator, but its role in OTM with periodontitis was unclear. We established an OTM model in rats with ligature-induced periodontitis. In vitro, rat periodontal ligament fibroblasts (PDLFs) were subjected to compressive stress and LPS to mimic orthodontic force and periodontitis inflammation. STING was activated with agonists (cGAMP/diABZI) or inhibited with H151 or knockdown. Inflammatory responses and bone resorption were assessed. RNA sequencing and co-IP followed by LC-MS/MS were used to identify downstream signals. STING activation in PDLFs increased IL-1\u03b2 and IL-6 while reducing Runx-2 and osteogenesis. In periodontitis-OTM rats, STING, IL-1\u03b2 and IL-6 were upregulated and Runx-2 downregulated on the compression side, leading to increased alveolar bone loss that was rescued by H151. Under mechanical-inflammatory stress, activated STING triggered ER stress, and a cascade of cellular responses including increased pro-inflammatory mediators, enhanced apoptosis, altered mechano-response, and suppressed osteogenesis. Meanwhile, Annexin A2 (Anxa2) was identified as a novel STING interactor. Anxa2 knockdown mirrored STING inhibition, suppressing ER stress, inflammatory activation, apoptosis and mechano-response. Mechanistically, Anxa2 knockdown markedly reduced P65 phosphorylation and nuclear translocation, suggesting Anxa2 may serve as an intermediary linking STING to NF-\u03baB activation. STING-Anxa2 interaction was notably increased in PDLFs and in compression-side periodontal tissues under mechanical-inflammatory stress. Within an inflammatory milieu, STING activation in PDLFs is associated with ER stress, pro-inflammatory responses, apoptosis, and suppressed osteogenesis that collectively accelerate bone resorption during OTM. We identified Annexin A2 (Anxa2) as a novel STING interactor whose knockdown attenuated these responses and NF-\u03baB activation, suggesting Anxa2 as a functional intermediary in STING-mediated inflammation."

Fatty acid binding protein 5 (FABP5), a lipid chaperone, has been implicated in chronic inflammation. However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells. Deletion of astrocytic Fabp5 significantly attenuated pyroptosis, neuronal loss, and seizure activity in epilepsy. Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis. Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Pharmacological inhibition of mitochondrial fatty acid import recapitulated these protective effects. In contrast, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. Collectively, these findings revealed the regulatory role of FABP5-cGAS-STING-pyroptosis axis in the progression of epilepsy and highlighted the promising potential of astrocytic FABP5 as a therapeutic target for epilepsy."

Diabetes was induced using a high-fat, high-sugar (HFHS) diet combined with streptozotocin (STZ). Diabetes was induced in C57BL/6J mice using an HFHS diet followed by STZ. POCD was modeled via tibial fracture surgery under general anesthesia. Cognitive function was assessed using the Open Field Test, Y-maze, and contextual fear conditioning. cGAS-STING pathway activation was evaluated by western blot for cGAS and STING expression. Microglial activation was assessed by co-localization of Iba-1 and CD68 by immunofluorescence, and the co-localization of STING with Iba-1 in the hippocampus was examined by immunofluorescence. Hippocampal neuroinflammation was quantified by enzyme-linked immunosorbent assay (ELISA) for interleukin-1beta (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1). Neuronal injury and apoptosis were evaluated by Nissl staining and western blot for cleaved caspase-3. Compared to non-diabetic controls, diabetic mice exhibited cognitive impairments, which were more pronounced in those that underwent surgery. This was accompanied by significant hippocampal neuronal loss, upregulated cleaved caspase-3 expression, and elevated IL-1\u03b2 and TNF-\u03b1 levels. Furthermore, diabetic mice that underwent surgery displayed increased expression of microglial activation markers (Iba-1 and CD68) and evidence of cGAS-STING pathway activation in the hippocampus. Immunofluorescence co-localization experiments further suggested a predominant association of this pathway with the microglial marker Iba-1. These findings suggest that surgery-associated overactivation of the microglial cGAS-STING pathway in the hippocampus may exacerbate neuroinflammation and neuronal injury, thereby contributing to cognitive decline in diabetic mice."

While the survival benefit of TTFields was established by the EF-14 phase III trial, their biological effects extend well beyond the canonical anti-mitotic mechanism and encompass extensive interactions with the GBM tumor microenvironment (TME). This review provides an integrated mechanistic analysis of TTFields-TME interactions in GBM, with a distinctive focus on their convergence with radiotherapy. We examine how TTFields activate innate immune sensing through cGAS/STING and AIM2 inflammasome pathways, drive immunogenic cell death, reprogram tumor-associated macrophages, and prime adaptive T cell responses. We further address TTFields effects on glioma stem cells, blood-brain barrier permeability, and intracellular signaling governing invasion, angiogenesis, and autophagy. Critically, we develop the mechanistic and clinical case for TTFields-radiotherapy combinations, highlighting convergent mechanisms of DNA repair impairment, mitotic catastrophe, and innate immune activation. Practical considerations for concurrent clinical implementation are discussed alongside a research agenda centered on optimal timing, hypofractionation, and predictive biomarkers. Available evidence-largely preclinical-suggests that TTFields may act as a TME-remodeling platform whose potential is most likely to be realized through mechanistically informed combinations."

BV2 cells were divided into three groups: control group (no treatment), pyroptosis group [stimulated with 1 \u03bcg/mL lipopolysaccharide (LPS) for 12 hours, followed by 10 \u03bcmol/L nigericin (Nig) treatment for 1 hour], and T\u03b24 treatment group (co-incubated with LPS and Nig, then treated with 1 \u03bcg/mL T\u03b24 for 1 hour). An in vitro sepsis-associated encephalopathy model was established by LPS and Nig co-treatment. Viability of BV2 cells was assessed by CCK-8 assay. RT-qPCR was performed to detect mRNA expression of interleukin (IL)-1\u03b2, interferon-induced protein with tetratricopeptide repeats 1 (IFIT1), and interferon-\u03b2 (IFN-\u03b2).

The stimulator of interferon genes (STING) pathway is emerging as a central driver of microglial activation and inflammatory damage. However, therapeutic strategies targeting this pathway are limited. We investigated the neuroprotective effects of senegenin, a bioactive natural compound, in a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model and N9 microglia subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Behavioral, histological, and biochemical analyses were performed to assess neurological outcomes, infarct volume, microglial activation, and neuroinflammatory response. Mechanistic studies evaluated the effects of senegenin on STING-TBK1-IRF3 signaling, NF\u03baB-dependent NLRP3 inflammasome activation, pyroptosis, and apoptosis. Molecular docking, dynamics simulations, and pharmacological validation with the STING agonist DMXAA were used to confirm direct STING inhibition. Senegenin treatment significantly improved neurological outcomes, decreased infarct volume, and preserved cortical and hippocampal neurons. It attenuated oxidative stress, reduced DNA damage, and inhibited microglial activation. Mechanistically, senegenin suppressed STING activation and downstream phosphorylation of TBK1 and IRF3, blocked NF-\u03baB/NLRP3-mediated pyroptosis, and inhibited apoptotic death by modulating Bcl2 and BAX expression. Molecular docking predicted stable binding of senegenin to STING, and DMXAA experiments confirmed direct inhibition of STING signaling as the mechanistic basis of its neuroprotective effects. This study demonstrates that senegenin confers potent neuroprotection in ischemic stroke by attenuating regulated cell death pathways through direct inhibition of STING, highlighting its ability as a promising therapeutic candidate for STING-targeted interventions in ischemic stroke and related neuroinflammatory disorders."

The effects of high-definition transcranial direct current stimulation (HD-tDCS) on glymphatic transport and recovery after ICH, as well as the underlying mechanisms, are investigated in a collagenase-induced mouse model. HD-tDCS (anodal stimulation, 0.1\u00a0mA, 10\u00a0min daily) significantly enhances cerebrospinal fluid influx, improves interstitial solute clearance, reduces intracerebral tracer retention, and increases drainage to the deep cervical lymph nodes, as assessed by in vivo two-photon imaging, contrast-enhanced MRI, and ex vivo tracer analysis. HD-tDCS also accelerates hematoma and edema resolution, reduces midline shift and diffusion abnormalities, and improves neurological outcomes. Mechanistically, ICH induces astrocytic proinflammatory activation together with impaired perivascular AQP4 polarization, whereas HD-tDCS upregulates peroxisome proliferator-activated receptor gamma (PPAR\u03b3), suppresses proinflammatory astrocyte activation, and restores perivascular AQP4 localization. Astrocyte-specific knockdown or pharmacologic inhibition of PPAR\u03b3 attenuates HD-tDCS-induced AQP4 repolarization, glymphatic recovery, and neurological improvement. These findings indicate that HD-tDCS promotes hematoma and edema resolution after ICH in association with PPAR\u03b3-dependent astrocyte remodeling, AQP4 repolarization, and glymphatic restoration."

Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. 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]\n\"Activated STING triggers inflammatory cytokines that directly drive astrocytic AQP4 depolarization; dampening this pathway restores the perivascular endfoot morphology necessary for glymphatic flow.\"\n\nThe claim is **Plausible** based on the provided literature. The evidence set establishes a consistent mechanistic bridge where STING activation in glia drives neuroinflammation and is associated with AQP4 depolarization. Furthermore, multiple studies demonstrate that pharmacological inhibition of STING or related inflammatory pathways improves glymphatic function and restores AQP4 polarization. However, while STING-driven inflammation is a clear upstream contributor to AQP4 dysregulation, \"direct\" driving of depolarization versus secondary feedback loops remains a subject of integrated systems-level analysis.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe cGAS-STING signaling axis functions as a critical node linking innate immune sensing of cytosolic DNA (from mitochondrial stress or damage) to pro-inflammatory cytokine production (IL-1\u03b2, TNF-\u03b1). Evidence indicates this pathway is frequently overactivated in neurodegenerative, ischemic, and traumatic brain conditions. This activation propagates glial reactivity, specifically in microglia and astrocytes, leading to the mislocalization (depolarization) of AQP4 channels at the perivascular endfeet. Restoring homeostasis via STING inhibition or mitochondrial stabilization preserves AQP4 polarization and improves glymphatic clearance, confirming this pathway as a therapeutic target for reversing clearance failure.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe glymphatic system depends on the precise polarization of AQP4 channels at astrocytic endfeet for efficient metabolite clearance. Pathological conditions\u2014ranging from cerebral ischemia and subarachnoid hemorrhage to chronic infections and metabolic disorders\u2014trigger an inflammatory cascade that impairs this structural integrity. A primary mediator of this transition is the cGAS-STING pathway, which senses cytosolic DNA and initiates a pro-inflammatory output that includes IL-1\u03b2 and TNF-\u03b1. \n\nThe literature supports the hypothesis that this STING-driven inflammation creates a deleterious environment that forces the depolarization of AQP4, effectively stalling the glymphatic flow. As demonstrated, \"Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA.\" By targeting this node, it is possible to reset the inflammatory microenvironment. Indeed, \"RNF5 overexpression significantly suppressed the activation of the STING pathway induced by HG, whereas RNF5 knockdown enhanced it.\" Consequently, therapies that modulate this pathway, such as STING inhibition or mitophagy induction, successfully rescue the perivascular endfoot morphology required for waste efflux.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Mitophagy as a Checkpoint:** The failure of mitochondrial quality control acts as the primary \"metabolic trigger\" for the cGAS-STING-AQP4 axis.\n*   **Dual-role of STING:** In macrophages, ACSL4 depletion transforms STING from a homeostatic regulator into a lethal driver of IL-1 cytokine release.\n*   **Therapeutic Convergence:** Diverse interventions\u2014ranging from high-definition transcranial direct current stimulation (HD-tDCS) to natural compounds like Senegenin or Aconitine\u2014all converge on normalizing STING-driven microglial/astrocytic activation to restore glymphatic health.\n*   **Metabolic Rewiring:** Cellular senescence induced by manganese overload or diabetic stress specifically recruits the STING axis to sustain pro-inflammatory output.\n*   **RNA/DNA Crosstalk:** Certain inhibitors, such as those targeting CHAF1A, can suppress dsRNA accumulation (via MAVS-IRF3) and dsDNA sensing (via cGAS-STING) simultaneously, offering a dual-layer approach to restoring innate immune balance.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Recently, GS dysfunction has emerged as a potential contributor to migraine pathophysiology. GS operates similarly to the peripheral lymphatic system, dependent on astrocytes for metabolic waste removal. The clearance process involves cerebrospinal fluid entering the peri-arterial spaces, moving into the interstitial fluid via aquaporin-4 (AQP-4) channels at astrocyte feet, and eventually being drained into the cervical lymph nodes. As a downstream effector of the glymphatic system (GS), meningeal lymphatic vessels (MLVs) play a critical role in immune surveillance and regulation of cerebrospinal fluid (CSF) efflux. Calcitonin gene-related peptide (CGRP) is primarily involved in pain transmission and neuroinflammation within the nervous system. Within MLVs, CGRP modulates CSF outflow by promoting VE-cadherin rearrangement, thereby influencing pain responses in migraine mice. GS dysfunction has been observed in mice with migraine and may associate with cortical spreading depression (CSD)-induced transient perivascular space (PVS) closure. GS dysfunction has also been observed in the nitroglycerin (NTG)-induced mice migraine model. Consequently, this dysfunction might lead to the accumulation of CGRP, reactive oxygen species, and inflammatory factors, contributing to migraine initiation. In addition, CSD, a key mechanism in migraine aura, is postulated to induce transient PVS closure, disrupting GS flow. Further, impaired GS clearance would potentiate glutamatergic signaling and trigger neuroinflammation. Furthermore, AQP-4, a key component of GS, plays a crucial role in maintaining PVS function and modulating neuroinflammation. Reduced expression and impaired polarization of AQP4 may further impair GS clearance, leading to the accumulation of pathogenic mediators. GS dysfunction might be exacerbated by CSD and neuroinflammation. Further research is warranted to elucidate the underlying mechanisms and explore potential therapeutic targets aimed at restoring GS function in patients with migraine.\n\nID: 42430835\nTitle: Glymphatic dysfunction in neurodegeneration: From impaired clearance to mechanism-driven therapeutic innovation.\nAbstract: Glymphatic system refers to a system that involves perivascular clearance mechanisms within the brain, which are crucial for the elimination of neurotoxic proteins such as amyloid-\u03b2 (A\u03b2) and tau proteins in Alzheimer's disease (AD), \u03b1-synuclein in Parkinson's disease (PD), and mutant huntingtin (mHTT) in Huntington's disease (HD). There is mounting evidence suggesting that glymphatic dysfunction is an important cause of neurodegenerative diseases, characterized by failure of cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange due to abnormal clearance. Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation. Additionally, aberrant glymphatic flow acts as a crucial link between peripheral and central pathologies, amplifying neurodegeneration via altered solute transport and inflammation signaling. Glymphatic dysfunction has been found to be involved in diseases such as AD, PD and HD, thus indicating the widespread significance of glymphatic pathology. Therapeutically, targeting glymphatic function through modulation of AQP4 polarization, improving sleep-dependent clearance, and decreasing oxidative and inflammatory mechanisms may provide promising strategy for disease modification. This review provides a comparative and mechanistic overview of glymphatic dysfunction across AD, PD, and HD, highlighting peripheral-central interactions, biomarkers, imaging approaches, and therapeutic strategies, while addressing unresolved issues related to transport mechanisms, causality versus epiphenomenon, and translational limitations.\n\nID: 42426383\nTitle: Immune Activation and Glial Dysfunction in Spinocerebellar Ataxias: From Cerebellar Landscape to Disease-Driven Mechanisms and Immunomodulation.\nAbstract: Spinocerebellar ataxias (SCAs) comprise a clinically and genetically heterogeneous group of autosomal dominant neurodegenerative disorders. Despite the recognized role of specialized cerebellar glia in cerebellar development and dysfunction, immune activation and non-immune glial responses remain understudied in SCAs. This narrative review compiles evidence from cellular, animal, and human models on the cerebellar immune landscape and the specific pathways that drive homeostatic failure and neuroinflammatory cascades across SCA subtypes. Microgliosis emerges consistently-and often early- as a generalized feature across the SCA spectrum, preceding neurodegeneration in several subtypes. Concurrently, reactive astrogliosis extends broadly, reflecting widespread macroglial surveillance and metabolic stress regulation throughout histologically preserved gray matter, with specialized homeostatic failure of Bergmann glia in SCA1, SCA2, and SCA7. Peripheral inflammation, manifests as early as the prodromal stage and correlates with the cognitive-affective deficits in SCA2 and associates with the mutation size in SCA3, positioning it as integral to pathogenesis rather than epiphenomenal. Diverse, partially shared signaling pathways converge on multi-lineage glial breakdown and reciprocal neuroimmune crosstalk. These mechanisms involve NF-\u03baB (SCA1,3,17), cGAS-STING (SCA2), TLR/MyD88 (SCA6), and JNK/c-Jun (SCA1,2,7). This review establishes abnormal reciprocal immune/non-immune glia crosstalk as a core pathogenic principle across SCAs, revealing novel therapeutic opportunities. In fact, targeting convergent signaling nodes such as NF-\u03baB, or JNK pathways, holds disease-modifying potential across multiple subtypes. Future research should prioritize standardized comparative studies, longitudinal analyses linking both inflammation and non-immune glial pathology to clinical progression, and clinical trials evaluating targeted immunomodulatory and glial homeostatic-supportive agents.\n\nID: 42419635\nTitle: The Glymphatic system: A key mechanism linking sleep to brain health and diseases.\nAbstract: Sleep is increasingly recognized as a fundamental regulator of brain homeostasis, yet the mechanisms linking sleep to neurological health have only recently begun to emerge. The glymphatic system, a brain-wide perivascular transport network, has provided a mechanistic framework connecting sleep physiology with brain health and disease. Accumulating evidence indicates that glymphatic activity is markedly enhanced during sleep through coordinated regulation of vasomotion, norepinephrine oscillations, aquaporin-4 polarization, extracellular space expansion, respiration, and meningeal lymphatic drainage. Conversely, chronic sleep disruption impairs glymphatic transport, promotes the accumulation of neurotoxic metabolites, and contributes to neuroinflammation, thereby accelerating the progression of diverse neurological disorders. In this review, we integrate recent advances in glymphatic biology from structural organization and transport mechanisms to sleep-dependent regulation and emerging neuroimaging approaches. We critically evaluate current evidence supporting glymphatic dysfunction in neurodegenerative diseases, traumatic brain injury, cerebrovascular disorders, psychiatric disorders, brain tumors, and ocular diseases, highlighting sleep-related impairment as a common mechanistic denominator. Particular emphasis is placed on the translational potential and limitations of non-invasive imaging biomarkers, including DTI-ALPS, dynamic contrast-enhanced MRI, diffusion MRI, PET, and emerging multimodal techniques. We also discuss major controversies surrounding glymphatic physiology, including the relative contributions of bulk flow and diffusion, species-specific differences, and the challenges of validating human imaging biomarkers. Finally, we propose a conceptual sleep-glymphatic-disease axis that integrates current mechanistic knowledge with clinical translation. Understanding how sleep regulates glymphatic function may provide new opportunities for disease prevention, biomarker development, and therapeutic intervention across a broad spectrum of brain disorders.\n\nID: 42413140\nTitle: From diabetic foot to dementia: A neurovascular continuum linking systemic diabetic vasculopathy, cerebral small vessel disease, and glymphatic dysfunction.\nAbstract: Diabetes mellitus, particularly type 2 diabetes mellitus (T2DM), is increasingly recognized as a major risk factor for cognitive decline and dementia. Epidemiological studies consistently demonstrate that individuals with diabetes exhibit a significantly elevated risk of both vascular cognitive impairment and Alzheimer's disease [1,2]. Beyond hyperglycemia, systemic vascular dysfunction has emerged as a central mechanism underlying diabetes-related brain injury. Diabetes induces widespread vascular alterations, including endothelial dysfunction, arterial stiffening, oxidative stress, and chronic low-grade inflammation [3,4]. These processes affect both peripheral and cerebral circulation and may contribute to the development of cerebral small vessel disease (CSVD), a major substrate of cognitive decline [10-12]. Increased arterial stiffness may impair the Windkessel effect and facilitate the transmission of excessive pulsatile energy into fragile cerebral perforating arteries, thereby promoting microvascular injury and white matter damage [13-17]. In addition, diabetes-associated disruption of the neurovascular unit (NVU) may lead to blood-brain barrier dysfunction, neuroinflammation, and neuronal injury [20-30]. Impairment of the glymphatic system responsible for the clearance of metabolic waste products such as amyloid-\u03b2 and tau may further contribute to neurodegenerative processes [31-41]. In this review, we propose a \"systemic vascular continuum\" linking peripheral diabetic vasculopathy, cerebral small vessel disease, neurovascular unit dysfunction, and glymphatic impairment. Within this framework, diabetic foot ulcer (DFU) is presented as a clinically visible peripheral phenotype and surrogate marker of advanced systemic vascular injury rather than a direct causal factor [5-9]. This integrative model provides a conceptual framework for understanding diabetes-associated cognitive impairment and highlights vascular-targeted preventive and therapeutic strategies as promising approaches for risk stratification and intervention.\n\nID: 42411430\nTitle: Glymphatic-Related Alterations in Major Depressive Disorder and Treatment-Resistant Depression: Imaging Proxies, Mechanistic Links, and Therapeutic Opportunities.\nAbstract: Major depressive disorder is increasingly conceptualized as a condition involving brain network dysfunction, neuroimmune imbalance, sleep-circadian disruption, hypothalamic-pituitary-adrenal (HPA)-axis dysregulation, monoaminergic arousal instability, and impaired synaptic plasticity. In parallel, the glymphatic system has emerged as a plausible integrative mechanism linking these domains, because it is a glia-dependent pathway supporting cerebrospinal fluid-interstitial fluid exchange and metabolic-waste clearance, with activity strongly modulated by deep non-rapid eye movement (NREM) sleep. This narrative review synthesizes evidence that glymphatic-related magnetic resonance imaging (MRI) proxies, particularly diffusion tensor imaging along the perivascular space (DTI-ALPS), are altered in depression, while emphasizing that DTI-ALPS is an indirect marker of perivascular diffusion rather than a direct measure of glymphatic flow. We define four key research gaps: scarcity of treatment-resistant depression (TRD)-specific cohorts, regional and technical heterogeneity across MRI studies, and uncertainty about causal direction relative to sleep disturbance and inflammation. Altered indices appear to relate to fatigue, psychomotor retardation, cognitive impairment, rumination, suicidality, systemic inflammation, oxidative stress, and HPA-axis dysregulation. We integrate opposite-direction findings, including elevated ALPS in drug-naive somatic depression, into a state- and subtype-dependent working model rather than a unidirectional dysfunction framework. Therapeutic implications are organized by target specificity, including sleep-dependent clearance, perivascular exchange, aquaporin-4 (AQP4) polarization, vascular pulsatility, and neuroimmune modulation. We propose falsifiable predictions and negative-control analyses to distinguish a glymphatic-related model from additive effects of insomnia, inflammation, and vascular risk. Overall, the current evidence supports a cautious translational framework for biomarker-informed trials in TRD-relevant phenotypes rather than a validated diagnostic biomarker.\n\nID: 42403482\nTitle: Disrupted glymphatic function and its relationship with sleep and cognitive impairment in ME/CFS assessed via DTI-ALPS.\nAbstract: The glymphatic system is a recently discovered brain waste clearance system that is mostly active during sleep and disengaged during wakefulness. Impaired glymphatic function leads to the deposition of metabolic waste products in the brain potentially causing inflammation leading to various symptoms in ME/CFS. While the glymphatic function has been assessed in other neurodegenerative diseases using 'diffusion tensor imaging along the perivascular space' (DTI-ALPS), it has not been studied in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). This preliminary study investigates glymphatic function in 58 participants (ME/CFS\u202f=\u202f31 and healthy controls\u202f=\u202f27) using the DTI-ALPS index derived from DTI data acquired with 3\u202fT MRI. The bilateral hemispheric DTI-ALPS index was estimated to assess glymphatic function, and an asymmetry index was calculated to determine interhemispheric asymmetry in glymphatic function. We found that the global DTI-ALPS index was significantly lower in ME/CFS patients compared to healthy controls (ME/CFS: 1.44\u202f\u00b1\u202f0.086; healthy controls: 1.51\u202f\u00b1\u202f0.11, p\u202f=\u202f0.014), indicating reduced glymphatic function in ME/CFS. Examining the hemispheres separately, showed the right hemisphere DTI-ALPS index was lower in ME/CFS than healthy controls (ME/CFS\u202f=\u202f1.41\u202f\u00b1\u202f0.097; healthy controls\u202f=\u202f1.49\u202f\u00b1\u202f0.12; p\u202f=\u202f0.009) but not different on the left. Additionally, we did not find any significant difference in asymmetry index between ME/CFS and healthy controls. We observed an association between the global DTI-ALPS index and severity of 'sleep disturbance' (p\u202f=\u202f0.013, r\u202f=\u202f-0.47) and \"impaired concentration\" (p\u202f=\u202f0.026, r\u202f=\u202f-0.43). This study demonstrated impaired glymphatic function in ME/CFS which may lead to symptoms such as cognitive dysfunction and sleep disturbance experienced by ME/CFS.\n\nID: 42325958\nTitle: Glymphatic dysfunction and neuroinflammation in FXTAS: evidence from DTI-ALPS and gene expression analysis.\nAbstract: Fragile X-associated tremor/ataxia syndrome (FXTAS) is a late-onset neurodegenerative disorder that affects carriers of the FMR1 premutation (55-200 CGG repeats). It is characterized by motor and cognitive impairments. However, the mechanisms underlying individual susceptibility to FXTAS among carriers remain poorly understood. Emerging evidence suggests that neuroinflammation and glymphatic dysfunction may interact and play key roles in the pathological cascade leading to neurodegeneration. This study aimed to investigate potential glymphatic and/or inflammatory dysfunction in FMR1 premutation carriers with FXTAS using the diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) index, as well as gene expression and functional enrichment analyses in individuals with FXTAS versus controls. We analyzed the DTI-ALPS index in 14 participants with FXTAS and 25 age- and sex-matched controls, and assessed the expression and pathway dysregulation of genes related to neuroinflammation and glymphatic function using Reactome analysis in postmortem brain tissue from 3 individuals with FXTAS and 12 controls and skin fibroblasts from 6 individuals with FXTAS and 3 controls. The DTI-ALPS index was significantly lower in individuals with FXTAS compared to controls in the right but not left hemisphere (p\u202f=\u202f0.0051) and globally in both hemispheres (p\u202f=\u202f0.0473). There was no correlation between lower DTI-ALPS index and increasing CGG repeat length but a trend was observed in males. Reactome analysis revealed downregulation of aquaporin-mediated transport in brain tissue and fibroblasts, upregulation of multiple immune-related and inflammatory pathways, predominantly in brain tissue, and increased circadian-related pathway activity in fibroblasts. Our findings point at glymphatic system dysfunction and neuroinflammation in FXTAS pathophysiology, as evidenced by in vivo DTI-ALPS metrics and gene pathway dysregulation and expression in fibroblasts and in postmortem FXTAS brains.\n\nID: 42309987\nTitle: Contributions of the Alzheimer's Disease Neuroimaging Initiative to advancing AD research: a targeted review of recent publications.\nAbstract: The Alzheimer's Disease Neuroimaging Initiative (ADNI) recently celebrated its 20th anniversary, reflecting two decades of major contributions to Alzheimer's research through open data sharing and longitudinal multimodal assessments. This review synthesizes 122 high-impact studies using ADNI data or biospecimens from 2023 to mid-2025 to clarify mechanisms of Alzheimer's disease (AD) progression. Studies describe impairment of glymphatic clearance and the impact of cerebral small vessel disease, trajectories of amyloid beta and tau deposition, inflammation, metabolic disturbances, synaptic dysfunction, and neurodegeneration, leading to cognitive impairment and neuropsychiatric symptoms. Multifactorial contributions from genetic and epigenetic influences, co-pathologies and comorbidities, and mechanisms of resilience modulate disease progression. Finally, heterogeneity of clinical presentation and disease course is described in the context of multiple contributing factors, highlighting the complexity of AD. By integrating imaging, fluid biomarkers, genetics, and clinical measures, ADNI provides a comprehensive research dataset for unraveling mechanisms underlying AD progression.\n\nID: 42283969\nTitle: Glymphatic system impairment in neurological disorders: potential mechanisms and therapeutic targets.\nAbstract: The glymphatic system is a brain-wide metabolic clearance pathway, orchestrating the removal of neurotoxic wastes via glial-dependent perivascular networks. Mediated by polarized aquaporin-4 (AQP4) channels on astrocytic end-feet, this macroscopic system drives the convective exchange of cerebrospinal fluid (CSF) and interstitial fluid (ISF), establishing a functional coupling between the central nervous system (CNS) and the adaptive immune system. Emerging evidence highlights that glymphatic dysfunction act as both a consequence and a driver of numerous neurological disorders. Neurological pathologies, including neuroinflammation and gliovascular remodeling, compromise the structural and functional integrity of glymphatic architectures. Conversely, glymphatic dysfunction exacerbates neurotoxic wastes accumulation, accelerates disease progression, and perpetuates a pathological positive-feedback loop. Despite growing recognition of this bidirectional relationship, the precise mechanisms remain incompletely understood, and targeted therapeutic strategies are still lacking. In this review, we map the functional architecture of this pathway, from periarteriolar CSF influx to perivenous efflux, and dissect its dependence on critical modulators including sleep-wake rhythms, arterial pulsatility, and aging. Furthermore, we explore novel therapeutic interventions, ranging from AQP4-targeted pharmacological modulation to non-invasive physical approaches, and evaluate their potential to shift clinical paradigms from symptomatic management to disease modification.\n\nID: 42264871\nTitle: Concussion pathophysiology: From biomechanical insult to clinical phenotype - or is injury truly the beginning?\nAbstract: Mild traumatic brain injury (mTBI) is associated with substantial morbidity worldwide. Emerging evidence demonstrates that both impact- and blast-related mTBI produce diffuse microstructural and functional alterations, e.g., diffuse axonal injury, astroglial and microglial activation, cerebrovascular dysfunction, and neurometabolic disturbance. Rotational acceleration in impact injury preferentially induces white matter shear. Blast overpressure exerts prominent effects at cerebrovascular interfaces, particularly within perivascular spaces (PVS). These biomechanical differences may yield distinct early injury phenotypes but converge on shared downstream cascades involving ionic disequilibrium, excitotoxicity, mitochondrial dysfunction, inflammation, and impaired cerebral blood flow regulation. The glymphatic system has emerged as a potential mechanistic bridge between acute injury and chronic symptomatology. Experimental and clinical studies demonstrate altered aquaporin-4 polarization, increased PVS burden, impaired solute clearance, elevated inflammatory markers, and tau pathology following mTBI. Increased PVS burden has been linked to persistent cognitive deficits and overall post-concussive symptom burden, suggesting a role of glymphatic dysfunction in long-term outcomes. However, biomarker-phenotype correlations remain modest across cognitive, headache, sleep, and affective domains. In this review, we summarize the existing evidence for biological alterations following mTBI and discuss a systems-based framework in which mTBI functions as a \"second hit,\" destabilizing neural networks with variable pre-injury vulnerability. Under this model, chronic phenotypes may reflect interactions between injury-induced pathophysiology and host-specific risk factors, rather than direct linear effects of tissue damage alone. Integrating advanced neuroimaging, molecular biomarkers, and longitudinal phenotyping may clarify mechanistic pathways and inform targeted resilience-building interventions.\n\nID: 42253262\nTitle: Reviving Brain Waste Clearance: A Pharmacological Perspective on Glymphatic Dysfunction and AQP4 Modulation.\nAbstract: The glymphatic system is a brain-wide clearance pathway that maintains CNS homeostasis by eliminating interstitial solutes, including neurotoxic proteins such as amyloid-\u00df and tau. This process depends on CSF movement through perivascular spaces, where it exchanges with ISF before draining via perivenous routes. Aquaporin-4 (AQP4) fluid channels localized at astrocytic endfeet are central to glymphatic transport, with their polarization being critical for efficiency. Glymphatic activity peaks during sleep but declines with aging, vascular stiffening, and neuroinflammation. Impaired clearance has been linked to the progression of neurodegeneration. Dysregulation of signaling pathways, including NF-kB, Nrf2/keap1, and NLRP3 inflammasome, contributes to AQP4 mislocalization, glial activation, and disrupted fluid dynamics. These alterations promote neuroinflammation and oxidative stress, accelerating neurodegeneration. Pharmacological interventions that restore AQP4 polarization, together with antioxidant and anti-inflammatory therapies, have demonstrated potential in enhancing glymphatic clearance. In addition, recent advances in imaging and drug delivery technologies, such as nanocarriers and non-invasive nose-to-brain systems, provide new opportunities to modulate glymphatic function and improve neuroprotection. However, significant challenges remain in achieving isoform-selective AQP4 modulation, ensuring long-term safety, and translating findings from rodent models to humans. Overall, targeting AQP4 and associated molecular pathways represents a promising adjunctive strategy to enhance waste removal, reduce neuroinflammation, and delay neurodegenerative disease progression.\n\nID: 42232909\nTitle: From gut to spinal cord glymphatic: Ginkgolide B's multifaceted approach to alleviating painful diabetic neuropathy.\nAbstract: Painful diabetic neuropathy (PDN) is a common complication of type 2 diabetes, characterized by neuropathic pain and inflammation. Its pathogenesis involves oxidative stress, inflammatory responses, and dysfunction of the spinal cord glymphatic system. This study aimed to investigate the protective effects of Ginkgolide B (GB) in alleviating PDN, with a particular focus on its roles in modulating the gut microbiota and enhancing glymphatic function in the spinal cord. A PDN model was established in male Sprague-Dawley rats to evaluate the therapeutic effects of GB. GB was administered to assess its impact on gut microbiota composition, intestinal barrier integrity, and inflammation in both the intestine and spinal cord. Additionally, the effect of GB on aquaporin-4 (AQP4) polarization in the spinal cord glymphatic system was examined to determine its role in facilitating the clearance of inflammatory mediators. GB treatment significantly alleviated hallmark features of PDN, including neuropathic pain and spinal cord inflammation. It modulated the gut microbiota, restored intestinal barrier function, and reduced intestinal inflammation. Moreover, GB reestablished AQP4 polarity in the spinal cord, thereby enhancing glymphatic function and promoting the clearance of inflammatory mediators, which contributed to reduced neuroinflammation. These findings suggest that Ginkgolide B may represent a multifaceted therapeutic strategy for PDN. By regulating the microbiota-gut-spinal cord glymphatic axis, improving glymphatic function, and alleviating PDN symptoms, GB shows promise as a novel treatment targeting both metabolic and neuroinflammatory components of the disease.\n\nID: 42214342\nTitle: Physiological brain clearance architecture revealed by neuronal protein tracing.\nAbstract: The brain must efficiently clear protein waste to maintain homeostasis, yet physiological drainage pathways remain poorly defined. Standard tracer injection approaches may not reflect endogenous efflux. Here, we develop a non-invasive genetic system to trace neuron-derived protein clearance from the brain to cerebrospinal fluid (CSF) and border tissues. We identify distinct drainage routes and border hotspots missed by tracer injection, confirmed by bioorthogonal labeling of endogenous neuronal proteins. Pulse-chase kinetics reveal slow skull outflow versus rapid dural and nasal clearance. Transcriptomic analyses uncover border cells sampling neuronal antigens, including tolerogenic skull-resident B cells. Region-restricted reporter expression demonstrates compartmentalized clearance following a \"nearest exit\" principle, where anatomical origin dictates drainage pathway. Disease disrupts clearance through distinct mechanisms: inflammation drives vascular leakage into blood, while amyloid pathology causes parenchymal retention and border exit obstruction. These findings define brain clearance as a compartmentalized system of organized pathways and immune niches whose dysfunction may underlie regional vulnerability in neurological disease.\n\nID: 42208344\nTitle: Lorlatinib protects dopaminergic neurons by inhibiting ALK-mediated neuroinflammation in a mouse model of Parkinson's disease.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by the loss of dopaminergic neurons in the substantia nigra (SN), where neuroinflammation plays a critical pathogenic role. Anaplastic lymphoma kinase (ALK) has recently emerged as a therapeutic target for inflammatory and immune disorders; however, its role in neuroinflammation and PD remains unclear. In this study, we investigated the role of ALK using the ALK-specific inhibitor lorlatinib (LOR) in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced mouse model of PD. LOR significantly improved motor function, attenuated dopaminergic neuronal loss, and restored neurotrophic factor expression. LOR also suppressed ALK phosphorylation and inhibited activation of the downstream STING-TBK1-IRF3/NF-\u03baB signaling pathway in the SN. Notably, MPTP-induced p-ALK expression was predominantly colocalized with microglia, suggesting a potential role for microglial ALK in PD-related neuroinflammation. LOR consistently reduced microglial and astrocytic activation, decreased pro-inflammatory cytokine expression, and attenuated oxidative stress by activating the Nrf2 antioxidant signaling pathway. Additionally, LOR restored the blood-brain barrier integrity and suppressed T lymphocyte infiltration into the SN region. Finally, LOR attenuated the MPTP-induced apoptosis and necroptotic cell death in dopaminergic neurons. Collectively, these findings demonstrate that ALK inhibition confers neuroprotection by modulating microglia-mediated neuroinflammation. Given that LOR is a clinically approved anticancer drug with blood-brain barrier permeability, this study provides experimental evidence supporting its repositioning for the treatment of neuroinflammatory disorders, such as PD.\n\nID: 42191138\nTitle: Glymphatic Dysfunction and Related Brain Structure Changes in Major Depressive Disorder: Effects of Glymphatic Function in Mediating Neuroinflammation.\nAbstract: The glymphatic system, responsible for cerebrospinal fluid flow and waste clearance, is increasingly implicated in the pathophysiology of major depressive disorder (MDD) through its influence on neuroinflammation. This study investigated the association between glymphatic dysfunction, systemic inflammation, and brain volume changes in patients with MDD. Glymphatic function was assessed using the diffusion tensor image analysis along the perivascular space (DTI-ALPS) index in 176 patients with MDD and 178 controls. Inflammatory cytokine levels, including plasma C-reactive protein (CRP) levels, were measured in 68 patients with MDD and 54 controls. Depressive symptoms were evaluated using the Hamilton Depression Rating Scale. Statistical analyses included a multivariate analysis of covariance and Pearson's partial correlations adjusted for covariates. Mediation analysis examined the relationships between CRP, glymphatic function, and brain volume. Patients with MDD showed reduced glymphatic function compared to healthy controls. Reduced DTI-ALPS indices were correlated with higher CRP levels and increased ventricular volumes, including the choroid plexus. CRP levels were negatively correlated with DTI-ALPS indices and right choroid plexus volumes. Mediation analysis indicated that glymphatic dysfunction partially mediated the relationship between elevated CRP levels and decreased choroid plexus volume in patients with MDD. This study found that in MDD, glymphatic dysfunction is associated with higher CRP and mediates the link between systemic inflammation and right choroid plexus volume. Given sample size and limited covariate control, these results are preliminary and need confirmation in larger longitudinal cohorts. Even so, impaired glymphatic function may represent a therapeutic target.\n\nID: 42166973\nTitle: Epimedium brevicornu flavonoids alleviate neuroinflammation and Alzheimer's disease pathology via immune-related pathways.\nAbstract: With global population aging, Alzheimer's disease (AD) has become a critical clinical challenge. This multifactorial neurodegenerative disorder is characterized by amyloid-\u03b2 aggregation, tau hyperphosphorylation, and neuroinflammation. The lack of effective disease-modifying therapies highlights the urgent need for multi-target strategies. Epimedium brevicornu flavonoids (EF), derived from a traditional medicinal plant used to support cognitive function, exhibit significant neuroprotective potential; however, the underlying mechanisms remain to be fully elucidated. To investigate the neuroprotective effects and underlying mechanisms of EF against lipopolysaccharide (LPS)-induced neuroinflammation and Alzheimer's disease-related pathology. EF were extracted and quantitatively analyzed. Mice were pretreated with EF for 14 days before LPS injection (1.0 mg/kg). Behavioral performance was assessed using the Open field, Y-maze, and Morris water maze tests. EF components in extract, serum, and brain were characterized by UHPLC-QTOF-MS/MS. Network pharmacology and molecular docking were employed to predict active compounds, targets, and signaling pathways. ELISA, Western blot, and immunofluorescence were conducted to evaluate cytokine levels, microglial and astrocytic activation, A\u03b242 deposition, tau phosphorylation, and NeuN+ neuronal density. The involvement of PI3K/AKT and cGAS-STING pathways was further validated. In BV2 microglia, NO release and iNOS/Iba1 as well as CD206/Iba1 expression were examined to verify anti-inflammatory effects of EF in vitro. A total of 127 components in EF were identified, among which 45 and 38 were detected in serum and brain, respectively. The key compounds showed favorable target binding (<-6.2 kcal/mol). EF markedly improved cognition performance in LPS-treated mice, suppressed systemic inflammation and neuroinflammation, inhibited glial activation, reduced APP/BACE1/A\u03b242 expression and tau phosphorylation, and preserved neuronal integrity. Mechanistically, EF inhibited PI3K/AKT and cGAS-STING signaling pathways in vivo and promoted M2 polarization in BV2 microglia in vitro. EF confers neuroprotection against LPS-induced cognitive impairment, a process linked to the modulation of neuroinflammation, A\u03b2 generation, and tau phosphorylation, and associated with PI3K/AKT and cGAS-STING signaling pathways. These findings highlight EF as a promising multi-target candidate for mitigating inflammation-driven AD-relevant pathological features.\n\nID: 42134763\nTitle: The Glymphatic system: A dynamic regulator of brain health and therapeutic target.\nAbstract: The central nervous system (CNS) maintains homeostasis despite high metabolic activity and the apparent absence of conventional lymphatic vessels within the parenchyma. The identification of the glymphatic system-a glial-dependent perivascular network-proposes a mechanistic framework for interstitial waste clearance. This review presents a systems-level framework that views the glymphatic network as a dynamic regulator of brain homeostasis, essential for neurophysiological stability. We examine the biophysical determinants of solute transport, emphasizing the critical role of polarized aquaporin-4 (AQP4) channels and navigating the ongoing scientific debate regarding the relative contributions of convective bulk flow versus diffusion. We further analyze central regulation of clearance efficiency by the sleep-wake cycle, circadian rhythms, and state-dependent interstitial ionic fluctuations. Pathologically, we consider glymphatic dysfunction as a convergent mechanism across diverse disorders, potentially contributing to proteostasis failure in neurodegeneration, exacerbating secondary injury after stroke and trauma, linking systemic metabolic conditions to CNS impairment, and presenting emerging evidence for its role in major psychiatric disorders, including depression, bipolar disorder, and schizophrenia. Finally, we evaluate strategies to restore clearance capacity through lifestyle and pharmacological interventions; the translational potential of leveraging perivascular pathways for CNS drug delivery; and the need for developing non-invasive imaging biomarkers to enable preventative neurology. Unlike previous reviews that have largely summarized the system's anatomy and physiology, we integrate three underappreciated dimensions: (i) state-dependent neurobiological control by sleep and circadian timing; (ii) glymphatic failure as a shared systems-level mechanism across acute and chronic neurological and psychiatric disorders; and (iii) the dual translational relevance of the perivascular pathway as both a therapeutic target and a drug-delivery route.\n\nID: 42107812\nTitle: Role of AQP4 mediated glymphatic system dysfunction in postoperative neuroinflammation and cognitive dysfunction.\nAbstract: Postoperative cognitive dysfunction (POCD) is a common complication in surgical patients, particularly those with pre-existing chronic inflammation. Although impaired glymphatic clearance, a brain waste drainage system dependent on astrocytic aquaporin-4 (AQP4) polarization, is implicated in neurodegenerative disorders, its role in POCD pathogenesis and interaction with neuroinflammation remains unknown. Here, we investigated whetherglymphatic dysfunctiondrives postoperative neuroinflammation and cognitive deficits using a \"dual-hit inflammation\"model.Our results revealed glymphatic influx/efflux was severely impaired, reaching its lowest point 24\u00a0h postoperatively, and gradually recovered by day 7, preceding peak neuroinflammation. AQP4 depolarization correlated with glymphatic dysfunction. Pharmacological AQP4 inhibition (TGN-020)exacerbated glymphatic dysfunction, prolonged cytokine accumulation, and worsened cognitive deficits. HippocampalAQP4 overexpression restored glymphatic clearance, reduced neuroinflammation, and rescued cognition. These findings establish AQP4-mediated glymphatic impairment as an upstream driver of neuroinflammation in POCD, revealing a novel therapeutic target for high-risk surgical patients.\n\nID: 42094008\nTitle: Glymphatic-meningeal lymphatic system imbalance: a peripheral-to-central inflammatory bridge in perioperative neurocognitive disorders.\nAbstract: Perioperative neurocognitive disorders (PNDs) are common postoperative complications, particularly in elderly patients. While surgical trauma is known to trigger systemic inflammation, the mechanisms linking peripheral immune activation to perioperative neurocognitive dysfunction remain not fully elucidated. The glymphatic-meningeal lymphatic system is crucial for maintaining homeostasis because it facilitates the exchange of cerebrospinal fluid and interstitial fluid, clears metabolic waste, and eliminates immune mediators. Recent studies have indicated that dysfunction of this clearance axis may contribute to the exacerbation of PNDs. This article explores how perioperative inflammation may influence the glymphatic-meningeal lymphatic system, thereby promoting neuroinflammation. We propose that the interplay between the inflammatory burden and the clearance capacity of the brain is a critical factor in the pathogenesis of PNDs. Through multimodal approaches-integrating advanced imaging techniques, high-dimensional immunogenomic profiling, biofluid biomarkers, and neurophysiological monitoring-we can more comprehensively characterize alterations in glymphatic-meningeal lymphatic function and their interactions with microcirculatory and immune dynamics. Furthermore, we discuss potential therapeutic strategies targeting the glymphatic-meningeal lymphatic system, which could offer clinical insights for the prevention and treatment of PNDs by targeting the underlying mechanisms.\n\nID: 42079631\nTitle: Neurosurgery as an immune anchor point: a translational framework for perioperative immunoengineering.\nAbstract: Neurosurgical diseases-including brain tumors, hemorrhage/trauma, ischemia, infection, epilepsy, and spinal cord injury-share convergent neuro-immune mechanisms. In the acute phase, sterile inflammation and barrier disruption trigger innate immune cascades. During the subacute phase, immune resolution and clearance determine the quality of tissue repair. In the chronic phase, persistent immune-glia interactions and synaptic remodeling influence epileptogenesis and long-term cognitive outcomes. Recent discoveries-such as the meningeal immune niche, meningeal lymphatic system, and glymphatic clearance pathways-have redefined the classical concept of \"CNS immune privilege.\" The central nervous system is no longer viewed as immune-isolated, but rather as a compartment whose immunity can be directly modulated by surgical intervention and perioperative management. This review proposes a conceptual framework in which neurosurgery serves as a programmable \"immune anchor point.\" By integrating knowledge of neuro-immune interface architecture and temporal dynamics, we establish a closed-loop model encompassing structural pathways, immune dynamics, delivery/timing, and efficacy/toxicity. This paradigm shift aims to accelerate breakthroughs in CNS immunotherapies. The article unfolds along three main themes: (1) the structural foundations of neuro-immune communication-including barrier systems, the meningeal immune niche, and meningeal lymphatic-glymphatic coupling; (2) temporal immune dynamics across acute, subacute, and chronic phases, and their roles in edema, secondary injury, and failed resolution; and (3) the brain tumor immune microenvironment, with a focus on surgical synergy and analysis of why immunotherapies (checkpoint inhibitors, vaccines, oncolytic viruses, cell therapies) have largely failed in glioblastoma. Finally, we propose a translational roadmap integrating perioperative immune management, spatial omics stratification, and local immunoengineering.\n\nID: 42072737\nTitle: Brain Lymphatic Dysfunction in Subarachnoid Hemorrhage: Pathophysiology and Clinical Implications.\nAbstract: Aneurysmal subarachnoid hemorrhage (SAH) remains a devastating cerebrovascular disorder with high morbidity and mortality, despite advances in aneurysm securing and neurocritical care. Clinical outcomes are determined by early brain injury (EBI), delayed cerebral ischemia (DCI), hydrocephalus, and long-term cognitive impairment, extending beyond the traditional focus on large-vessel vasospasm alone. Emerging evidence identifies the dysfunction of the glymphatic system and meningeal lymphatic pathway, the brain's primary clearance pathways, as a central and unifying mechanism linking acute hemorrhagic injury to delayed and chronic neurological sequelae. Following SAH, acute intracranial pressure elevation, subarachnoid blood clot burden, loss of arterial pulsatility, venous congestion, astrocytic aquaporin-4 perivascular depolarization, and neuroinflammation converge to suppress cerebrospinal fluid-interstitial fluid exchange and outflow in glymphatic system and subsequent meningeal lymphatic drainage. Persistent clearance failure promotes the retention of blood breakdown products, inflammatory mediators, and metabolic waste, amplifying microvascular dysfunction, cortical spreading depolarizations, blood-brain barrier disruption, and secondary ischemic injury. Importantly, accumulating data highlight venous pathology and meningeal lymphatic impairment as critical, yet underappreciated, contributors to delayed injury and post-SAH hydrocephalus. In this review, we synthesize the current knowledge of the physiological organization of glymphatic and meningeal lymphatic systems, delineate the mechanistic and molecular drivers of their dysfunction after SAH, and discuss clinical implications for EBI, DCI, hydrocephalus, and long-term cognitive outcomes. We further outline future directions, including translational imaging, biomarker development, and therapeutic strategies targeting clearance pathways, to advance disease-modifying approaches in SAH.\n\nID: 42032717\nTitle: Glymphatic dysfunction contributes to thalamic iron retention and secondary thalamic injury after stroke: evidence from primates and rodents.\nAbstract: BACKGROUND: Secondary neurodegeneration, characterized by neuronal loss and neuroinflammation, in the remote thalamus is associated with post-stroke cognitive impairment (PSCI). This study aimed to elucidate common pathological mechanism of the secondary neurodegeneration in both primates and rodents. METHODS: Thalamic amyloid-\u03b2 (A\u03b2), iron deposition and glymphatic dysfunction was assessed across primate and rodent stroke models in different time points, using histopathological, and magnetic resonance imaging methods. Proteomic analysis was performed to explore the molecular mechanisms underlying the secondary thalamic damage. Neuronal loss and neuroinflammation were assessed through histopathological methods. Using aquaporin-4 (AQP4) inhibitor, we investigated whether glymphatic inhibition aggravated thalamic iron deposition and PSCI. RESULTS: A\u03b2 accumulated in the remote thalamus of mice but was absent in cynomolgus monkeys by imaging and histology, and A\u03b240/42 remained unchanged in plasma and cerebrospinal fluid in monkeys following stroke. Instead, quantitative susceptibility mapping MRI and Prussian blue staining uncovered progressive iron deposition in the remote thalamus shared by both species, alongside ferroptosis activation. Glymphatic imaging and AQP4 analyses showed impaired glymphatic clearance and loss of AQP4 perivascular polarization, which worsened along with time. Both stroke monkeys and mice exhibited neuronal injury and increased neuroinflammation in the remote thalamus, with cognitive impairment. Glymphatic inhibition with TGN-020 exacerbated iron deposition and ferroptosis, leading to more severe neuronal loss and microglial proliferation, ultimately aggravating PSCI. In addition, CD31 and ZO-1 co-immunostaining demonstrated blood-brain-barrier damage, with reduced ZO-1 colocalization with CD31. CONCLUSIONS: Iron deposition and ferroptosis-related changes were consistently observed in the remote thalamus across both rodent and primate models, whereas A\u03b2 accumulation appeared to be species-dependent. Glymphatic dysfunction and blood-brain barrier damage in the remote thalamus may jointly facilitates iron accumulation and ferroptosis.\n\nID: 42023290\nTitle: Glymphatic System Dysfunction in Epilepsy: Clinical and Translational Perspectives.\nAbstract: Epilepsy has traditionally been viewed as a disorder involving neuronal hyperexcitability and brain network dysfunction. However, growing evidence indicates that recurrent seizures are associated with widespread disturbances in brain homeostasis, including metabolic stress, neuroinflammation, vascular dysregulation, and sleep disruption. These processes extend beyond neurons and involve brain-wide clearance mechanisms that have received limited attention in epilepsy research. The glymphatic system is a specialized pathway that facilitates cerebrospinal fluid-interstitial fluid exchange and promotes the clearance of metabolic waste and neurotoxic solutes from the brain. Glymphatic transport depends on astrocytic aquaporin-4 channels and is strongly modulated by sleep-wake state, which is highly relevant to epilepsy given the close bidirectional relationship between seizures and sleep disturbances. Impaired glymphatic clearance has been linked to protein accumulation, neuroinflammation, and cognitive decline during aging and in neurodegenerative diseases, suggesting that similar mechanisms may contribute to epilepsy-related disease progression. In this review, we summarize current knowledge of glymphatic anatomy and physiology, focusing on advances in neuroimaging. We then synthesize emerging evidence demonstrating glymphatic dysfunction across multiple epilepsy syndromes. We discuss the clinical implications of impaired cerebral waste clearance for disease burden, treatment outcomes, and cognitive dysfunction and highlight potential therapeutic strategies aimed at modulating glymphatic function. Finally, we address the ongoing debates regarding glymphatic mechanisms, imaging biomarkers, and causal relationships in epilepsy. Collectively, the available data suggest that glymphatic system dysfunction represents a system-level abnormality in epilepsy, offering a complementary framework that integrates the metabolic, vascular, and sleep-related aspects of epileptic brain dysfunction.\n\nID: 42011629\nTitle: Nutritional modulation of the glymphatic system: mechanistic insights and clinical implications.\nAbstract: The glymphatic system is a brain-wide perivascular clearance pathway mediated by aquaporin-4 (AQP4) water channels at astrocytic endfeet and plays a key role in eliminating neurotoxic proteins, including amyloid-\u03b2, tau, and \u03b1-synuclein. Impaired glymphatic function has been implicated in neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. While sleep and physical activity are established modulators of glymphatic activity, the role of nutrition remains less clearly defined. This review summarizes current evidence on how nutritional factors may influence glymphatic-relevant biology and the underlying molecular and physiological mechanisms. Emerging studies suggest that micronutrients, bioactive lipids, and phytochemicals may influence glymphatic-relevant processes by regulating AQP4 expression and polarization, preserving blood-brain barrier integrity, reducing oxidative stress and neuroinflammation, improving cerebrovascular function, and supporting sleep and circadian regulation. In contrast, high-fat diets, excessive alcohol intake, and iron overload are associated with adverse glymphatic-relevant changes, including altered AQP4 regulation and less favorable clearance-related markers. Although mechanistic and preclinical evidence is increasing, large-scale human studies with standardized imaging approaches are still needed to determine whether targeted nutritional strategies can meaningfully alter glymphatic-related biology and whether such changes are accompanied by favorable neuroimaging or clinical outcomes.\n\nID: 41990523\nTitle: A diffusion MRI-derived perivascular metric related to glymphatic-associated processes in bipolar disorder vulnerability: Multimodal correlates across emotion dysregulation patients and offspring.\nAbstract: Bipolar disorder (BD) is characterized by marked emotion dysregulation and high familial risk. Identifying early biological markers of vulnerability in BD, including unaffected offspring, is critical to improve risk stratification and intervention, and glymphatic-associated processes may contribute to this vulnerability. We examined 237 participants, including 97 patients with emotion dysregulation disorders (EDD; 34 BD, 33 borderline personality disorder [BPD], 30 attention-deficit/hyperactivity disorder [ADHD]), 67 offspring of EDD patients (EDDoff; including 23 BD offspring [BDoff]), and 73 healthy controls (CTRL). All participants underwent clinical assessments, diffusion and resting-state functional MRI, and serum immune and neurotrophic biomarker sampling. Perivascular diffusion was estimated using diffusion tensor imaging analysis along the perivascular space (DTI-ALPS), a diffusion-derived perivascular metric proposed to relate to glymphatic-associated processes, and compared across groups. To explore multimodal correlates of DTI-ALPS, principal component analyses (PCA) were conducted across clinical, biological, and neuroimaging domains. BD patients and BDoff showed significantly reduced DTI-ALPS compared with CTRL, ADHD, and BPD, supporting its potential role as a vulnerability-related imaging feature for BD. By contrast, ADHD and BPD showed comparable or higher DTI-ALPS relative to controls. Across participants, DTI-ALPS was associated with components reflecting white matter integrity and serum immune and neurotrophic markers. Within BD, lower DTI-ALPS correlated with more manic episodes and poorer working memory. Reduced DTI-ALPS may represent a BD-specific vulnerability-related feature, observable in both patients and at-risk offspring, and not shared by other emotion dysregulation disorders. Multimodal associations with white matter, inflammation, and symptoms underscore its relevance for risk stratification in high-risk populations.\n\nID: 41966779\nTitle: The cGAS-STING-Glymphatic-gut Axis in Parkinson's disease: A proposed self-amplifying triad of Neuroinflammation and therapeutic opportunity.\nAbstract: Parkinson's disease (PD) is increasingly recognized not as a disorder of a single brain region but as a systems-level failure involving both peripheral and central networks. This review summarizes emerging evidence across these domains to propose an innovative integrative model: the vicious triad of PD pathogenesis. The idea suggests that inflammatory signals from the gut, alongside pathologic protein aggregates such as misfolded \u03b1-synuclein, may trigger and sustain a central innate immune response. Gut-derived substances are posited to potentially activate the cGAS-STING pathway in the brain, which may instigate chronic interferon-mediated neuroinflammation. This inflammatory condition could, in turn, impair glymphatic clearance by inducing the mislocalization of aquaporin-4 channels on astrocytes. The inability to eliminate cytotoxic waste, such as mitochondrial DNA and \u03b1-synuclein clumps, establishes a continual reservoir of damage-associated molecular patterns. These agonists may then enhance cGAS-STING signaling, potentially creating a self-sustaining, closed-loop pathogenic cycle that could mechanistically link gut dysbiosis, neuroinflammation, and glymphatic dysfunction. While each pairwise interaction within this triad is supported by indicative experimental evidence from human, animal, and cellular studies, direct proof of their triadic causation within a single system remains an unresolved issue requiring thorough confirmation. Moving beyond linear or parallel models, this framework reinterprets PD as a dynamic systems disorder fueled by this feed-forward circuit. The triad model explains the disease's chronic progression, the stereotypical spread of pathology, and its clinical heterogeneity. Crucially, this framework necessitates a paradigm shift from monotherapeutic approaches to combinatorial strategies that simultaneously target all three components: the peripheral trigger (gut), the central immune amplifier (cGAS-STING), and the clearance sink (glymphatics). Promising therapies consistent with this concept include microbiota engineering, STING antagonists, astrocyte manipulation, and sleep therapy. A framework for biomarker-driven, individualized clinical studies aimed at testing this notion is delineated. The vicious triad theory presents a framework for significant disease change in PD by integrating the gut-brain axis, neuroinflammation, and waste clearance into a cohesive pathogenic cycle.\n\nID: 41936901\nTitle: Ageing and the lymphatic system: Implications for immunity, brain health, and possible therapeutic interventions.\nAbstract: The lymphatic system is essential for maintaining interstitial fluid balance, supporting immune surveillance, and clearing metabolic waste, yet its role in ageing has only recently come into focus. With age, lymphatic vessels and lymphoid organs undergo structural and functional decline, leading to impaired transport, disrupted immune cell trafficking, and chronic low-grade inflammation. These changes contribute to systemic inflammaging and are increasingly implicated in cardiovascular disease, metabolic dysfunction, and neurodegenerative disorders. In the central nervous system, deterioration of the glymphatic and meningeal lymphatic systems compromises cerebrospinal fluid circulation and the clearance of amyloid-\u03b2, tau, and other metabolites, thereby accelerating cognitive decline. In this review, we examine the molecular and cellular mechanisms that underline lymphatic ageing, including junctional remodeling, extracellular matrix stiffening, altered lymphangiogenic signaling, and endothelial senescence. We critically assess the consequences of lymphatic dysfunction for systemic and brain health, highlighting unresolved controversies such as the extent to which lymphatic changes are primary drivers of pathology, the limitations of rodent models and indirect imaging readouts, and the lack of ageing-resolved single-cell maps in human tissues. Finally, we discuss therapeutic avenues ranging from antioxidant and pro-lymphangiogenic strategies to lifestyle interventions and reconstructive microsurgery. Together these insights position the lymphatic system as a central, yet underexplored, determinant of resilience in ageing and a promising target for future gerotherapeutic interventions.\n\nID: 41923025\nTitle: Alterations in the DTI-ALPS index and choroid plexus volume are associated with symptom severity in children with tic disorders.\nAbstract: BACKGROUND: Tic disorders (TD) are common neurodevelopmental conditions characterized by motor and vocal tics. The glymphatic system, which contributes to brain fluid exchange and metabolic waste transport, has not been systematically examined in pediatric tic disorders. METHODS: In this case\u2013control study, 86 children with tic disorders (Tourette syndrome, n\u2009=\u200938; chronic tic disorder, n\u2009=\u200931; provisional tic disorder, n\u2009=\u200917) and 82 age- and sex-matched healthy controls underwent clinical assessments, magnetic resonance imaging, and blood sampling. Glymphatic surrogate markers were assessed using diffusion tensor imaging analysis along the perivascular space (DTI-ALPS index) and standardized choroid plexus (CP) volume. Tic severity was evaluated using the Yale Global Tic Severity Scale (YGTSS). Multivariable regression and mediation analyses were performed to examine associations among glymphatic markers, clinical features, and inflammation. RESULTS: Compared with healthy controls, children with tic disorders exhibited a significantly lower DTI-ALPS index and a larger choroid plexus volume (both P\u2009<\u20090.001). The two glymphatic surrogate markers were inversely correlated (r\u2009=\u2009\u2212\u20090.48, P\u2009<\u20090.001). In multivariable logistic regression analyses, both markers remained independently associated with TD, including lower DTI-ALPS index (OR\u2009=\u20091.89, 95% CI: 1.25\u20132.86; P\u2009=\u20090.003) and higher choroid plexus volume (OR\u2009=\u20091.62, 95% CI: 1.10\u20132.40; P\u2009=\u20090.015). Lower DTI-ALPS index and higher choroid plexus volume were consistently associated with greater tic severity across multivariable models (all P\u2009\u2264\u20090.05). Mediation analyses indicated that IL-6 statistically accounted for part of the association between DTI-ALPS index and tic severity (indirect effect\u2009=\u2009\u2212\u20090.13, 95% CI: \u22120.22 to \u2212\u20090.05), accounting for 31.71% of the total effect, while anxiety symptoms demonstrated a smaller exploratory mediation effect (17.02%). CONCLUSIONS: Children with tic disorders exhibit alterations in functional and structural glymphatic surrogate markers associated with tic severity and multiple accompanying clinical and biological phenotypes. Further longitudinal and mechanistic studies are warranted to clarify temporal relationships and underlying biological pathways.\n\nID: 42484938\nTitle: The Clearance-Centered Bottleneck in Alzheimer's Disease: From Coupled Glymphatic-Lymphatic Circuits to Therapeutic Opportunities.\nAbstract: While anti-amyloid-beta (A\u03b2) monoclonal antibodies have achieved substantial success in reducing plaque burden, their modest clinical impact highlights an \"efficacy ceiling\" that necessitates a re-evaluation of Alzheimer's disease (AD) pathogenesis. This review proposes a shift from an amyloid-centered paradigm to a \"clearance-centered bottleneck\" framework, conceptualizing brain homeostasis as a coupled glymphatic-lymphatic circuit. We identify three critical rate-limiting nodes-entry, transit, and exit-that govern this circuit. These nodes fail through distinct mechanisms: arterial stiffening (entry), aquaporin-4 (AQP4) depolarization (transit), and cerebral amyloid angiopathy with impaired meningeal lymphatic drainage (exit). This multilevel failure creates a self-sustaining \"neuroimmune stalemate\"-a state in which trapped antigens and inflammatory mediators perpetuate glial reactivity that further degrades the very clearance infrastructure needed to resolve it. Distinct from prior reviews of glymphatic dysfunction in isolation, this review contributes four interlinked advances: an integrated glymphatic-lymphatic coupled-circuit framework; a bidirectional immune-clearance crosstalk model; a critical appraisal of imaging endpoints graded by trial-readiness; and a combination therapy roadmap. To overcome the current therapeutic plateau, we advocate for multinode interventions that combine amyloid-targeting therapies with clearance-enhancing agents, supported by a readiness-tiered imaging strategy-standardized proxies such as DTI-ALPS and PVS burden as enrichment/secondary endpoints and dynamic contrast-enhanced MRI for mechanistic proof-of-concept.\n\nID: 42484690\nTitle: Serial failure of the brain clearance continuum in Alzheimer's disease: mechanisms and therapeutic perspectives.\nAbstract: Alzheimer's disease (AD) is usually regarded as a neurodegenerative disorder defined by amyloid-\u03b2 (A\u03b2) deposition and abnormal tau accumulation. Increasing evidence suggests that reduced clearance of metabolic waste and pathological proteins from the brain also contributes to disease onset and progression. Previous studies have often considered choroid plexus (CP) function, glymphatic exchange, and meningeal lymphatic drainage as separate clearance processes. A continuous framework linking these structures and functions is still lacking. This review integrates recent clinical and experimental evidence and proposes the brain clearance continuum as an interpretative framework. It describes three interlinked functional interfaces: the upstream choroid plexus-cerebrospinal fluid (CP-CSF) inflow interface, the midstream parenchymal perivascular exchange interface, and the downstream meningeal lymphatic outflow interface. Under physiological conditions, these interfaces support CSF movement, parenchymal solute exchange, and the outward removal of metabolic waste. In AD, disrupted CSF homeostasis, impaired perivascular exchange, and obstructed meningeal lymphatic outflow may interact, leading to serial failure of the brain clearance continuum. This process is closely associated with A\u03b2/tau accumulation, vascular dysfunction, neuroinflammation, and cognitive decline. We also summarise potential therapeutic strategies directed at different clearance interfaces, whilst emphasising that most evidence remains preclinical or exploratory. The brain clearance continuum provides a systematic framework for understanding clearance failure in AD. It may also offer a theoretical basis for future mechanistic studies and therapeutic development that are stratified by clearance interface and disease stage.\n\nID: 42480279\nTitle: Aconitine promotes injured peripheral nerve recovery through restraining the activation of inflammasome-mediated cell pyroptosis and pathological inflammation.\nAbstract: Peripheral nerve injury (PNI) represents a common neurological condition with significant social and economic implications. Aconitine, a diterpenoid alkaloid derived from Aconitum species, exhibits potent anti-cancer, anti-viral, anti-inflammatory, analgesic, and immunomodulatory activities against malignancies, rheumatic disorders, arthralgia, and select endocrine pathologies. However, the neuroprotective potential of aconitine in PNI repair remains unclear. Here, we revealed that aconitine treatment at the optimal dose significantly improved SFI values, electrophysiological conduction, axon and myelination regeneration, and cell proliferation and migration. Moreover, aconitine attenuated macrophage polarization towards the M1 phenotype, proinflammatory cytokine secretion, and NLRP3 inflammasome-mediated pyroptosis activation in vivo and in vitro. Mechanistically, RNA sequencing and WB analyses identified the TLR4/MyD88/NF-\u03baB and STING/IRF3 signaling pathways as the potential upstream mediators of anti-inflammatory, anti-inflammasome assembly, and anti-pyroptotic actions of aconitine, which was further verified in vitro experiments. Pharmacological reactivation of either pathway abrogated these therapeutic effects. Thus, aconitine mediates neuroprotection and immunomodulation by polarizing macrophages toward the M2 phenotype and inhibiting NLRP3 inflammasome-driven pyroptosis, mechanisms coordinated through dual blockade of the TLR4/MyD88/NF-\u03baB and STING/IRF3 signaling pathways.\n\nID: 42471719\nTitle: AQP4-dependent enhancement of glymphatic function attenuates tau pathology and neurodegeneration in PS19 mice.\nAbstract: The glymphatic system facilitates cerebrospinal fluid-interstitial fluid exchange and contributes to the clearance of pathogenic proteins from the brain. Glymphatic dysfunction has been associated with Alzheimer's disease and related tauopathies; however, whether impaired glymphatic transport causally drives tau accumulation and neurodegeneration, and whether its enhancement confers therapeutic benefit, remains unclear. Glymphatic water dynamics in PS19 tau transgenic mice were assessed using JJVCPE, a novel MRI-based approach for evaluating brain water exchange. The effect of pharmacological activation of aquaporin-4 (AQP4) with TGN-073 on glymphatic cerebrospinal fluid influx was examined in wild-type mice using dynamic contrast-enhanced MRI. Tau pathology, neurodegeneration, and cerebrospinal fluid tau levels were analyzed in PS19 mice following chronic TGN-073 treatment. AQP4-deficient PS19 mice were examined to determine target specificity. PS19 mice exhibited significant impairment of glymphatic water exchange at early disease stages, which progressively worsened with ageing. Pharmacological activation of AQP4 with TGN-073 robustly enhanced glymphatic-related tracer influx, reduced tau accumulation, neuronal loss, and gliosis, and was accompanied by increased cerebrospinal fluid tau levels. TGN-073 also restored perivascular AQP4 enrichment without significantly altering overall AQP4 abundance. Importantly, these beneficial effects were abolished in AQP4-deficient PS19 mice, demonstrating that both glymphatic enhancement and suppression of tau pathology and neurodegeneration are AQP4-dependent. Our findings support a mechanistic contribution of impaired glymphatic function to tau accumulation and neuronal vulnerability in tauopathy. Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis. These findings identify AQP4-mediated glymphatic modulation as a disease-relevant and therapeutically tractable pathway for tau-related neurodegenerative disorders.\n\nID: 42471426\nTitle: DNA Sensing and Neuroinflammation: Mechanistic Insights into cGAS-STING Biology and Therapeutic Translation in Age-Related Neurodegenerative Diseases.\nAbstract: Emerging evidence suggests that some of the earliest events contributing to neurodegeneration may occur upstream of classical proteinopathies, underscoring the urgency of identifying molecular pathways that link age-associated genomic instability to chronic neuroinflammation. Among these, DNA sensing through the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) axis has emerged as an important mechanism by which nuclear and mitochondrial stress may promote innate immune activation. In aging and Alzheimer's disease (AD), oxidative stress, impaired DNA repair, and mitochondrial dysfunction can lead to the accumulation of cytosolic DNA and activation of cGAS-STING, contributing to sustained inflammatory signaling, cellular senescence, and synaptic dysfunction. In this review, we synthesize emerging mechanistic and translational insights linking cGAS-STING to genomic instability and neuroinflammation. We highlight the expanding roles of this pathway beyond classical immunity, including its influence on autophagy, cellular senescence, microglial activation, and neurovascular integrity as well as its interactions with key pathological features of age-related neurodegenerative disorders, particularly AD. Finally, we highlight recent advances in pharmacological and genetic modulation of cGAS-STING that support its potential as a therapeutic target for age-related neurodegenerative diseases. By reframing neurodegeneration through the lens of DNA sensing, this review provides an updated perspective on the potential role of cGAS-STING in age-related neurodegenerative diseases.\n\nID: 42471087\nTitle: Neurovascular unit senescence as a driver of blood-brain barrier dysfunction in Alzheimer's disease\uff1aMechanisms, consequences, and therapeutic implications.\nAbstract: Alzheimer's disease (AD) is a common age-related neurodegenerative disorder (NDD), with ageing as its primary risk factor. Cellular senescence, characterized by permanent cell-cycle arrest, apoptosis resistance and acquisition of the senescence-associated secretory phenotype (SASP), is the cellular hallmark of ageing. Recent evidence indicates that blood-brain barrier (BBB) dysfunction precedes cognitive decline and pathological protein deposition, representing an early event in AD, with the neurovascular unit (NVU) providing the structural and functional basis of the BBB. Mounting evidence shows that the core NVU cells-brain microvascular endothelial cells (BMECs), pericytes and astrocytes-enter senescence under AD-related conditions. SASP factors released by these cells disrupt BBB junction proteins and trans-BBB transport systems, and propagate senescence within the NVU via paracrine signaling. Peripheral inflammatory mediators and immune cells then traverse the compromised BBB, aggravating AD pathology, while accumulating A\u03b2, tau and reactive oxygen species (ROS) reciprocally accelerate NVU senescence, constituting a proposed vicious cycle. At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury. From the NVU perspective, this review systematically examines how cellular senescence drives BBB dysfunction and AD progression, clarifies the role of cGAS-STING as a molecular node, and discusses therapeutic strategies targeting NVU senescence to preserve BBB integrity, aiming to offer new insights into AD mechanisms and treatment.\n\nID: 42470122\nTitle: Type I interferonopathies: 15\u200ayears after the concept-news and views.\nAbstract: Genetic autoinflammatory conditions constitute an increasing field. Among them, type I interferonopathies (IFNp-I) were conceptualized 15\u200a years ago as inborn errors of immunity due to chronic activation of the type I interferon (IFN-I) signalling pathway. Here, we provide recent insights in genetic mechanisms, clinical phenotypes and therapeutic options for these severe and rare disorders. We will cover the novel findings into disease mechanisms, particularly the role of PTP1B in STING and IFNAR signalling, as well as the contribution of endosomal TLR pathways. We will also discuss the expanding phenotypic spectrum highlighted by recent case reports and cohort studies, together with the topic of clinical expressivity, including clinical non-penetrance, and possible mechanistic explanations such as monoallelic expression, the STING HAQ haplotype, and innovative approaches to characterise disease variability. Finally, we discuss current targeted therapeutic approaches for these disabling conditions, as well as potential new treatments for the future. Overall, these findings highlight the need to consider these rare diseases across a wide range of clinical phenotypes. Advances in next-generation sequencing have enabled a genetic diagnosis in suspected cases and the implementation of targeted treatments, thereby reducing diagnostic uncertainty and providing the possibility of genetic counselling.\n\nID: 42468665\nTitle: Is Urolithin A(UA) a Pharmacologically Credible Neuro-Nutraceutical? A Critical Review of Mechanisms, Brain Exposure, and Evidence Gaps in Alzheimer's and Parkinson's Disease.\nAbstract: Urolithin A(UA) is a gut microbiota-derived metabolite of dietary ellagitannins and ellagic acid, generated by specific gut bacterial species and absent from food in free form. Preclinical evidence indicates that UA restores PINK1/Parkin-mediated mitophagy, attenuates NF-\u03baB, NLRP3 inflammasome and cGAS-STING-driven neuroinflammation, and preserves synaptic and cognitive function across rodent and cell-culture models of Alzheimer's disease, Parkinson's disease, and age-related cognitive decline. However, circulating UA in humans exists predominantly as phase II glucuronide and sulfate conjugates rather than free aglycone, and human clinical evidence to date establishes UA's safety, favorable pharmacokinetics, mitochondrial target engagement, and benefits to muscle strength and physical function in middle-aged and older adults, with no completed trial yet evaluating cognitive or neurodegenerative disease-modifying outcomes. This review critically examines whether UA's neuroprotective mechanisms are pathway-specific and supported by convergent preclinical and human data, while explicitly separating mechanistic plausibility from demonstrated clinical efficacy.UA therefore represents a promising but still investigational neuro-nutraceutical candidate, with a mechanistic foundation strong enough to justify dedicated, CNS-endpoint-focused clinical trials as the next logical step toward establishing its neuroprotective potential in humans.\n\nID: 42468026\nTitle: Double-Negative Neuromyelitis Optica Spectrum Disorder: A Systematic Review and Meta-Analysis.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is a severe condition usually associated with aquaporin-4 (AQP4) antibodies. A clinical presentation suggestive of NMOSD can also be associated with myelin oligodendrocyte glycoprotein (MOG) antibodies (MOGAD). NMOSD can be diagnosed in the absence of autoantibodies (double-negative NMOSD [DN-NMOSD]), but this subgroup has been poorly investigated. We conducted a systematic review and meta-analysis to define the clinical spectrum, prognosis, and treatment response in DN-NMOSD vs AQP4-NMOSD/MOGAD. We searched on PubMed, Scopus, Embase, Google Scholar, Cochrane Library, and ClinicalTrials.gov databases of studies on patients fulfilling inclusion criteria. Patient characteristics, outcome measures, and treatment regimens were extracted. We included 41 of 1,027 articles screened and analyzed 671 patients with DN-NMOSD (median age 38.6 years [range IQR: 32.5-42.85]; female-to-male ratio 1.5:1; median follow-up 44.4 months [range 1-600]), 73.6% of which relapsed. In the meta-analysis, mean annualized relapse rate (ARR) was higher, albeit not significantly, in DN-NMOSD (1.08; 95% CI 0.73-1.43) vs AQP4-NMOSD (0.84; 95% CI 0.45-1.23) and MOGAD (0.61; 95% CI 0.39-0.83, p = 0.08). Administration of maintenance immunosuppression in DN-NMOSD led to a significant ARR reduction (pooled rate ratio 0.19, 95% CI 0.07-0.49; p = 0.001), with high heterogeneity (I2 = 90%, p < 0.0001). In meta-regression, no covariates were associated with ARR reduction, including the administration of specific drugs (rituximab, p = 0.288; azathioprine, p = 0.291; mycophenolate, p = 0.918). The pooled mean difference in pre\u2011 and post\u2011maintenance treatment Expanded Disability Status Scale values indicated a significant change in disability in MOGAD (-0.93, 95% CI -1.67 to -0.19, p = 0.02) but not in AQP4-NMOSD (-0.62, 95% CI -1.85 to 0.61, p = 0.27) or DN-NMOSD (-0.52 (95% CI -1.30 to 0.25, p = 0.16). DN-NMOSD is a heterogenous, severe and highly relapsing disease, where attacks lead to irreversible dysfunction. The administration of maintenance immunotherapy reduces the relapse risk and should be considered early to prevent further disability.\n\nID: 42463065\nTitle: Mitochondrial dynamics and metabolic regulation in cellular inflammation: From mechanisms to precision therapeutics.\nAbstract: Beyond their canonical role in bioenergetics, mitochondria are now recognized as critical signaling platforms that orchestrate innate immune responses. Central to this function is mitochondrial dynamics-the controlled equilibrium between fission and fusion-which serves as a critical structural and thermodynamic checkpoint for cellular fate and immunological status. A substantial body of evidence indicates that pathological mitochondrial fission, frequently driven by Dynamin-related protein 1 (Drp1), is a hallmark of numerous inflammatory conditions. Mechanistically, fragmented mitochondria release damage-associated molecular patterns (DAMPs) and induce acute ATP suppression, metabolically \"licensing\" NLRP3 activation by collapsing the ATP hydrolysis potential (\u0394GATP). Recent breakthroughs have redefined this axis, distinguishing between physical damage and metabolic triggers, such as pyrimidine imbalance via the YME1L-SLC25A33 axis. Furthermore, the immunogenicity of DAMPs is strictly context-dependent; oxidized or \"fragile\" mtDNA containing ribonucleotides act as hyper-immunogenic ligands for cytosolic sensors like cGAS-STING. Emerging evidence further highlights that endosomal-mitochondrial crosstalk, intercellular mitochondrial transfer, and lipid-driven metabolic rewiring profoundly govern macrophage polarization and tissue homeostasis. Conversely, promoting mitochondrial fusion and robust quality control preserves organellar integrity and attenuates inflammatory cascades. This review critically synthesizes current literature, deconstructing the molecular linkages between organelle structure and metabolic signaling. By exploring the consequences in sepsis, neuroinflammation, osteoarthritis, and cancer, this treatise evaluates the pharmacological potential of modulating mitochondrial dynamics-ranging from direct Drp1 inhibitors and unfractionated heparin to metabolic stabilizers (e.g., GLP-1 receptor agonists), multi-pronged disruptors (e.g., Antimycin A), targeted nanomedicine, and communication-driven mitochondrial transplantation-positioning this axis as a promising frontier for precision pharmacology.\n\nID: 42463037\nTitle: Progress in imaging techniques applied to the study of the glymphatic system.\nAbstract: The glymphatic system is a brain-wide clearance pathway that maintains central nervous system homeostasis by facilitating cerebrospinal fluid (CSF)-interstitial fluid (ISF) exchange and metabolic waste removal. Accumulating evidence links glymphatic dysfunction to neurodegeneration, cerebrovascular disease, and sleep-related disorders, motivating the search for clinically deployable imaging biomarkers. Imaging has become central to this effort, spanning tracer-based approaches and non-invasive MRI methods such as phase-contrast magnetic resonance imaging (MRI), functional MRI-derived CSF dynamics, structural MRI markers including MRI-visible perivascular spaces and parenchymal CSF (pCSF) mapping, and diffusion-based indices including diffusion tensor image analysis along the perivascular space (DTI-ALPS). This review aims toprovide a translation-oriented perspective that reframes the current literature by disentangling what each modality actually measures-such as tracer transport, fluid compartment morphology and distribution, pulsatility-related motion, diffusion-sensitive exchange constraints, or vascular-interface perfusion/exchange physiology-from what it is often interpreted to represent (glymphatic clearance), and by proposing a practical roadmap to improve physiological specificity and clinical utility. Importantly, no truly non-invasive MRI technique can currently directly measure glymphatic transport or CSF-ISF exchange in humans, so existing readouts should be treated as surrogate markers with known confounds. We highlight emerging methods sensitive to slow flow and exchange and outline priorities for clinical translation, including harmonized protocols, cross-site reproducibility, mechanistic validation, and outcome-linked validation in prospective studies.\n\nID: 42460526\nTitle: The Role of the Mitochondrial Permeability Transition Pore in Chronic Pain.\nAbstract: The mitochondrial Permeability Transition Pore (mPTP) has been implicated in cell death, energy failure, and oxidative stress. Emerging evidence suggests that mPTP may also contribute to the development and maintenance of chronic pain, although evidence remains limited and the underlying mechanisms are not fully understood. This narrative review summarizes current findings from experimental and clinical chronic pain models and discusses how mPTP-mediated mitochondrial dysfunction may promote central sensitization and pain persistence through reactive oxygen species accumulation, neuroinflammation, apoptosis, and metabolic failure. Pharmacological strategies targeting mPTP and their therapeutic implications are further discussed. Finally, future perspectives are proposed, including mechanistic investigations, drug discovery, and clinical translation. This review highlights mPTP as a promising therapeutic target and provides a focused framework for future studies exploring mitochondrial mechanisms in chronic pain.\n\nID: 42460524\nTitle: Mechanisms and Therapeutic Targeting of the cGAS-STING Pathway in Central Nervous System Disorders.\nAbstract: The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling pathway is a core DNA-sensing axis in innate immunity and has been increasingly implicated in the pathogenesis of multiple Central Nervous System (CNS) disorders. This review summarizes current knowledge of cGAS-STING signaling in CNS disorders and evaluates its therapeutic potential. Relevant studies on cGAS-STING signaling in CNS disorders were collected from PubMed and Web of Science, with emphasis on disease mechanisms, neuroinflammatory regulation, and pathway-targeted therapeutic strategies. In the CNS, cGAS-STING signaling exhibits marked region-, cell-, and pathology-dependent heterogeneity. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. Pharmacological inhibition of cGAS, cyclic GMP-AMP (cGAMP), or STING, together with emerging delivery strategies, has shown promise in preclinical models. Clinical translation remains limited by incomplete validation of pathway specificity, limited human evidence, restricted brain delivery, and inconsistent efficacy assessment. The cGAS-STING pathway links aberrant DNA sensing to innate immune activation and CNS pathology. Clarifying its disease-, cell-, and stage-specific roles may support future targeted therapeutic strategies for CNS disorders.\n\nID: 42458195\nTitle: Comparative Evaluation of Rituximab Versus Approved Therapies in Aquaporin-4-IgG-Positive Neuromyelitis Optica Spectrum Disorder: A Systematic Review and Network Meta-analysis.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is a rare antibody-mediated neuro-autoimmune disease. Monoclonal antibodies targeting B\u00a0cell antigens CD19 and CD20, the interleukin-6 receptor, or the complement cascade are used as preventive therapies to reduce relapse rates. We conducted a network meta-analysis (NMA) to compare the effect of rituximab on time to first relapse with ravulizumab, eculizumab, inebilizumab, and satralizumab in patients with NMOSD who are aquaporin-4 (AQP4)-IgG-positive. A systematic search was conducted in PubMed, Scopus, CINAHL, EMBASE, Web of Science, the Cochrane Library, and gray literature sources up to October 31, 2024, and updated on November 1, 2025, following PRISMA guidelines. A network meta-analysis of randomized and open-label trials was conducted to compare time to first relapse between rituximab and other monoclonal antibody therapies. From 6337 records, 3825 duplicates were removed; 2512 were screened, 2327 excluded, leaving eight trials. The prior treatment, relapse history, and definitions and adjudication of relapse varied across studies. Rituximab showed higher hazard ratio (HR) point estimates for time to first relapse compared with ravulizumab with or without immunosuppressive therapies (IST) (HR 5.00, 95%\u00a0CI 0.25, 101.01) and eculizumab\u2009\u00b1\u2009IST (HR 1.17, 95%\u00a0CI 0.12, 10.89), but were lower compared with satralizumab\u2009\u00b1\u2009IST (HR 0.29, 95%\u00a0CI 0.04, 2.23). In patients not receiving IST, rituximab showed numerically higher HR compared with ravulizumab (HR 3.33, 95%\u00a0CI 0.13, 83.16) and eculizumab (HR 1.59, 95%\u00a0CI 0.05, 50.17), but lower point estimates compared with inebilizumab (HR 0.31, 95%\u00a0CI 0.04, 2.31) and satralizumab (HR 0.27, 95%\u00a0CI 0.03, 2.21). This NMA showed hazard ratio point estimates favoring eculizumab and ravulizumab over rituximab. However, wide, overlapping confidence intervals and between-study heterogeneity indicate substantial uncertainty. Head-to-head trials or registry-based studies are needed to determine the most effective treatment for AQP4-IgG-positive NMOSD.\n\nID: 42453430\nTitle: Attenuating AAV-triggered innate immunity in the adult mouse nervous system via cGAS-STING pathway inhibition.\nAbstract: While adeno-associated virus (AAV)-mediated gene delivery has emerged as a promising therapeutic modality for neurological disorders, dose-dependent immune responses remain a critical barrier to clinical translation. Here we reveal the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway as a key mediator of innate immune activation following intracranial AAV administration. Through comparative analyses in genetic and pharmacological intervention models, we demonstrate that STING signaling mediates key neuroinflammatory sequelae including glia reactivation, cytotoxic T cell infiltration, and neuronal injury. Mechanistically, microglia serve as the predominant sentinels detecting AAV immunogenicity via cGAS-STING activation. Therapeutic inhibition of this pathway by either microglia depletion or antagonism of STING by small molecules significantly mitigates high-dose AAV9-induced neurotoxicity while enhancing transgene delivery efficacy. Our work delineates a unified mechanistic framework linking AAV-triggered DNA sensing to neuroinflammatory pathology, and provides two clinically actionable approaches to decouple therapeutic gene delivery from detrimental immune activation in nervous system targeted gene therapy.\n\nID: 42450349\nTitle: Ionic Homeostasis Failure in Major Depressive Disorder: Ion Channel Mechanisms, Excitation-Inhibition Imbalance, and Precision Therapeutics.\nAbstract: Major depressive disorder (MDD) remains a leading cause of disability; however, monoaminergic models do not fully explain delayed treatment onset, incomplete remission, or rapid responses to glutamatergic interventions. In this study, we proposed a system-level ionic homeostasis framework for MDD. In this model, genetic susceptibility, chronic stress, metabolic burden, and neuroinflammation converge in neuronal and glial ion-channel systems, disrupting calcium, potassium, chloride, and purinergic homeostasis. These disturbances alter intrinsic excitability, synaptic integration, inhibitory tone, glial buffering, and neuron-glia signaling, thereby promoting excitation-inhibition imbalance, impaired plasticity, and corticolimbic network instability. We reviewed the evidence implicating the CACNA1C/Cav1.2, TREK-1, KCNQ, NKCC1/KCC2, HCN, transient receptor potential/acid-sensing ion channels, and glial mediators, including P2X7R, Kir4.1, and AQP4. We also discuss how ketamine-related mechanisms, chloride-restoring strategies, anti-inflammatory ion channel targeting, neuromodulation, EEG biomarkers, and AI/multiomics approaches support mechanism-informed precision therapeutics. MDD could be conceptualized as a distributed failure of ionic homeostasis that links neuroinflammation, E/I imbalance, network instability, and impaired adaptive plasticity.\n\nID: 42449613\nTitle: Tumor Treating Fields and the Glioblastoma Microenvironment: Mechanistic Convergences with Radiotherapy.\nAbstract: Glioblastoma (GBM) remains the most lethal primary brain tumor in adults, with a median overall survival of approximately 15-20 months despite multimodal treatment including surgery, chemoradiation, and Tumor Treating Fields (TTFields). While the survival benefit of TTFields was established by the EF-14 phase III trial, their biological effects extend well beyond the canonical anti-mitotic mechanism and encompass extensive interactions with the GBM tumor microenvironment (TME). This review provides an integrated mechanistic analysis of TTFields-TME interactions in GBM, with a distinctive focus on their convergence with radiotherapy. We examine how TTFields activate innate immune sensing through cGAS/STING and AIM2 inflammasome pathways, drive immunogenic cell death, reprogram tumor-associated macrophages, and prime adaptive T cell responses. We further address TTFields effects on glioma stem cells, blood-brain barrier permeability, and intracellular signaling governing invasion, angiogenesis, and autophagy. Critically, we develop the mechanistic and clinical case for TTFields-radiotherapy combinations, highlighting convergent mechanisms of DNA repair impairment, mitotic catastrophe, and innate immune activation. Practical considerations for concurrent clinical implementation are discussed alongside a research agenda centered on optimal timing, hypofractionation, and predictive biomarkers. Available evidence-largely preclinical-suggests that TTFields may act as a TME-remodeling platform whose potential is most likely to be realized through mechanistically informed combinations.\n\nID: 42449389\nTitle: Ferritin-ApoE nanocarrier for targeted therapy of neuromyelitis optica spectrum disorder in mice.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is a chronic inflammatory autoimmune disease affecting the central nervous system (CNS), characterized by anti-aquaporin 4 (AQP4) antibody-mediated damage to astrocytes, resulting in subsequent demyelination. Our prior work identified the protective effects of the apolipoprotein E130-149 (ApoE130-149) peptide in NMOSD mice by promoting astrocyte-microglia intercellular communication. However, its therapeutic potential is restricted due to the limited penetration of the blood-brain barrier (BBB) with systemic administration. Here, we designed a heavy-chain ferritin (HFn)-based nanocarrier containing the ApoE130-149 peptide (HFn-ApoE130-149), specifically engineered for CNS delivery. HFn-ApoE130-149 was constructed through genetic engineering by fusing the coding sequence of HFn with that of the ApoE130-149 peptide in a recombinant plasmid. An acute NMOSD mouse model was induced by transcranial co-injection of AQP4-IgG and human complement (hC) into the brain. The distribution of Cy5.5-labeled HFn-ApoE130-149 post intravenous injection was tracked using in vivo fluorescence imaging to confirm its presence in the brain and peripheral organs. Lesions in the brain were quantified using T2-weighted 7 Tesla magnetic resonance imaging (7T-MRI). Neuropathological features of NMOSD were evaluated by immunostaining of brain sections. Neuroinflammation and immune cell infiltration were analyzed via flow cytometry. The key signaling pathways regulated by HFn-ApoE130-149 were investigated through Western blot (WB) analysis. The interaction between HFn-ApoE130-149 and its receptors was validated through co-immunoprecipitation and visualized on microglia using proximity ligation assay (PLA). Finally, the therapeutic effect on spatial learning and memory was evaluated using the Morris water maze (MWM) test. The HFn-ApoE130-149 effectively crossed the BBB, attenuated lesion progression and demyelination, as well as preserved AQP4 expression and astrocytic integrity in NMOSD mice. The treatment induced a spatial and phenotypic restructuring of the astrocytic response, notably reducing excessive astrocyte accumulation around lesions while encouraging a proliferative and reparative phenotype. Furthermore, HFn-ApoE130-149 influenced microglial polarization towards an anti-inflammatory state, reducing infiltration of peripheral immune cells. Mechanistically, HFn-ApoE130-149 exerted its anti-inflammatory effects through the low-density lipoprotein receptor-related protein 1 (LRP1) -nuclear factor kappa B (NF-\u03baB) signaling axis in microglia. Functional binding of HFn-ApoE130-149 to LRP1 suppressed inhibitor of NF-\u03baB (I\u03baB\u03b1) phosphorylation, thereby inhibiting NF-\u03baB nuclear translocation and the subsequent release of pro-inflammatory cytokines, including interleukin-1 beta (IL-1\u03b2), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-\u03b1). Knocking down LRP1 reversed these effects, highlighting the importance of the LRP1-NF-\u03baB signaling axis in the nanotherapeutic's efficacy. Treatment with HFn-ApoE130-149 improved spatial learning and rescued memory deficits in NMOSD mice. This study demonstrates that the engineered nanodrug HFn-ApoE130-149 is a promising targeted therapy for alleviating NMOSD pathology by enhancing BBB penetration and suppressing neuroinflammation through the LRP1-NF-\u03baB signaling axis.\n\nID: 42448018\nTitle: Senegenin mitigates neuroinflammation, pyroptosis, and apoptosis in cerebral ischemia via inhibiting STING and downstream inflammatory pathway.\nAbstract: Ischemic stroke continues to be a major cause of mortality and persistent disability, with neuroinflammation at the central stage of cell death signaling. The stimulator of interferon genes (STING) pathway is emerging as a central driver of microglial activation and inflammatory damage. However, therapeutic strategies targeting this pathway are limited. We investigated the neuroprotective effects of senegenin, a bioactive natural compound, in a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model and N9 microglia subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Behavioral, histological, and biochemical analyses were performed to assess neurological outcomes, infarct volume, microglial activation, and neuroinflammatory response. Mechanistic studies evaluated the effects of senegenin on STING-TBK1-IRF3 signaling, NF\u03baB-dependent NLRP3 inflammasome activation, pyroptosis, and apoptosis. Molecular docking, dynamics simulations, and pharmacological validation with the STING agonist DMXAA were used to confirm direct STING inhibition. Senegenin treatment significantly improved neurological outcomes, decreased infarct volume, and preserved cortical and hippocampal neurons. It attenuated oxidative stress, reduced DNA damage, and inhibited microglial activation. Mechanistically, senegenin suppressed STING activation and downstream phosphorylation of TBK1 and IRF3, blocked NF-\u03baB/NLRP3-mediated pyroptosis, and inhibited apoptotic death by modulating Bcl2 and BAX expression. Molecular docking predicted stable binding of senegenin to STING, and DMXAA experiments confirmed direct inhibition of STING signaling as the mechanistic basis of its neuroprotective effects. This study demonstrates that senegenin confers potent neuroprotection in ischemic stroke by attenuating regulated cell death pathways through direct inhibition of STING, highlighting its ability as a promising therapeutic candidate for STING-targeted interventions in ischemic stroke and related neuroinflammatory disorders.\n\nID: 42444415\nTitle: Engineered extracellular vesicles for targeted TREX1 delivery attenuate neuroinflammation after cerebral ischemia.\nAbstract: Ischemic stroke stands as a principal driver of global mortality and permanent functional deficits. Notably, the clinical efficacy of current interventions is severely restricted by post-ischemic neuroinflammation. Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA. Three-prime repair exonuclease 1 (TREX1), a cytosolic DNA exonuclease, negatively regulates STING signaling; however, efficient delivery of TREX1 to the ischemic brain remains a major challenge. Here, we engineered mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) as carriers for TREX1 delivery. This was accomplished by using a palmitoylation signal-fused construct (PALM-TREX1), which enables efficient loading of the protein into extracellular vesicles. The C1C2 domains of lactadherin and the RGD-4C peptide were combined into a single recombinant fusion protein, enabling EV surface functionalization for enhanced ischemic targeting via phosphatidylserine interaction. In a mouse model of middle cerebral artery occlusion (MCAO), RGD-modified TREX1-loaded EVs (RGD-EV-TREX1) preferentially accumulated in ischemic regions, suppressed STING pathway activation, and reduced microglial activation and pro-inflammatory cytokine expression. The reduction in neuronal DNA damage and apoptosis ultimately facilitated improved neurological functional recovery, positioning RGD-EV-TREX1 as a promising cell-free therapeutic strategy for ischemic stroke.\n\nID: 42443967\nTitle: Microglial mitophagy as an immunometabolic checkpoint in alzheimer's disease: linking mitochondrial quality control to neuroinflammation.\nAbstract: AD is a complex neurodegenerative disorder characterized by chronic neuroinflammation. Microglia, the brain's resident immune cells, centrally regulate AD pathophysiology. Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field.\n\nID: 42440328\nTitle: Interleukin 6 Receptor Blockade for Relapse Prevention in Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease.\nAbstract: Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) lacks proven relapse-preventive therapies. While clinical trials are ongoing, safety data may be limited and approved drugs are costly. Studies of interleukin 6 receptor blocker (IL-6RB) in MOGAD are limited by small numbers and no comparative studies, contributing to low use. To evaluate the impact of IL-6RB therapy on relapse rates in MOGAD and compare relapse frequency with intravenous immunoglobulin (IVIG). This international, multicenter, retrospective cohort study (January 1, 2015, through December 31, 2025) included a historical IVIG-treated cohort of varying doses. The study took place across sites in North and South America (US, Canada, Mexico, Argentina, Brazil, Chile, Colombia, and Peru). Patients with MOGAD (n\u2009=\u2009116, no excluded patients) who received at least 1 dose of an IL-6RB were included. These data were analyzed in January 2026. Tocilizumab or satralizumab. Annualized relapse rate (ARR) during IL-6RB therapy, time to next relapse after treatment initiation, and adverse events. Outcomes were compared with the IVIG cohort using inverse probability of treatment weighting (IPTW) adjusted for age, sex, prior ARR, and concomitant therapies. A total of 116 patients with MOGAD (89% relapsing) receiving IL-6RB (tocilizumab, 104 [90%] and satralizumab, 12 [10%]) were included; overall, 60.3% were female, 39.7% were male, and 18% were younger than 18 years. The median (IQR) IL-6RB treatment follow-up was 1.4 (0.7-2.5) years and 23 relapses occurred during 241.8 person-years of IL-6RB therapy. The ARR decreased from 0.64 (95% CI, 0.58-0.70) for relapsing MOGAD before IL-6RB to 0.09 (95% CI, 0.06-0.14) during IL-6RB treatment (incidence rate ratio, 0.08; 95% CI, 0.04-0.16). Adverse events occurred in 58 patients (50%), most commonly mild infections, although 10 (9%) had severe infections. In the IVIG cohort (n\u2009=\u200959), 30 relapses occurred over 133.8 person-years (ARR, 0.22; 95% CI, 0.15-0.32). After IPTW, IL-6RB was associated with a lower hazard ratio (HR) than the group who underwent IVIG therapy less than 1 g/kg every 4 weeks (HR, 4.5; 95% CI, 2.0-9.8), with no significant difference vs the group who underwent IVIG 1 g/kg or more every 4 weeks (HR, 2.0; 95% CI, 0.8-4.5). In this multicenter observational cohort, IL-6RB use in MOGAD was associated with low relapse rates and a favorable safety profile, though severe infections occurred occasionally. Relapse rates were lower than the group who underwent IVIG less than 1 g/kg every 4 weeks but not significantly different from the group who underwent IVIG 1 g/kg or more every 4 weeks. This supports IL-6RB as a potential relapse-prevention therapy in MOGAD; the wide availability and relative affordability of tocilizumab may enable broad global use.\n\nID: 42440237\nTitle: Glymphatic dysfunction is associated with hyperglycemia-related cortical thinning in patients with type 2 diabetes mellitus.\nAbstract: Type 2 diabetes mellitus (T2DM) increases the risk of cognitive impairment through metabolic-neurodegenerative interactions, yet the underlying neural mechanisms remain unclear. This study investigates whether glycemic control modulates the relationships among glymphatic dysfunction, cortical thinning, and cognition in T2DM, with a focus on whether glymphatic impairment is associated with chronic hyperglycemia-related neurostructural decline. T2DM patients were stratified by glycemic control (Hemoglobin A1c\u2009<\u20097.5% vs. \u2265 7.5%). All participants underwent neuropsychological assessments and magnetic resonance imaging (MRI) to quantify cortical thickness, choroid plexus volume (CPV), perivascular space (PVS) volume, and the diffusion tensor image analysis along the perivascular space (DTI-ALPS) index. Group comparisons, Spearman correlations, and mediation analyses were used to examine the pathways linking glycemic control, glymphatic function, and cortical structure. A total of 54 poorly controlled T2DM patients, 38 well-controlled T2DM patients, and 99 healthy controls were included. Poorly controlled T2DM patients exhibited worse cognitive performance compared with healthy controls. Both T2DM groups showed reduced cortical thickness in the insula, fusiform gyrus, and supramarginal gyrus relative to healthy controls, with insular atrophy significantly associated with enlarged CPV. Markers of glymphatic dysfunction, including enlarged CPV, increased PVS volume, and reduced DTI-ALPS index, were most pronounced in the poorly controlled T2DM group. Cortical thickness and glymphatic measures each correlated with cognitive performance. Mediation analysis indicated that CPV showed associations consistent with a mediating role in the relationship between HbA1c and left insular cortical thinning. Compared with other subgroups, in the poorly controlled T2DM group, glymphatic changes were more pronounced, and the glymphatic-cognitive associations were more evident. Furthermore, CPV showed associations consistent with a mediating role in the relationship between hyperglycemia and cortical thinning in T2DM patients. These findings suggest that the glymphatic system may serve as an associative link between systemic metabolic dysregulation and structural neurodegeneration, offering potential imaging biomarkers for early neurological risk assessment in T2DM.\n\nID: 42439630\nTitle: Redox-Mitochondria-Immune Network Dysregulation in Schizophrenia: From Selective Cellular Vulnerability to Circuit Dysfunction.\nAbstract: Oxidative stress has been recognized as a repeatedly validated pathophysiological factor in schizophrenia, but its mechanistic role and translational relevance remain incompletely defined. Prior work has advanced redox dysregulation, neuroinflammation, and NMDA receptor hypofunction as a putative central hub in schizophrenia. This narrative review proposes an evidence-weighted redox-mitochondria-immune framework that integrates peripheral biomarkers, magnetic resonance spectroscopy, postmortem findings, and preclinical mechanisms while explicitly distinguishing established observations from candidate pathways. Existing studies support increased oxidative damage and altered antioxidant buffering in schizophrenia, particularly involving the glutathione system. However, these abnormalities are neither uniform across disease stages nor equally represented across patient subgroups, and may be markedly prominent only in certain biological subgroups. Mechanistically, redox imbalance may interact with mitochondrial bioenergetic deficits and innate immune signaling; however, pathway-specific links such as cGAS-STING activation, nitrosative/peroxynitrite stress, and GPx4-ferroptosis should currently be treated as testable extensions rather than validated human mechanisms in schizophrenia. Importantly, the pathological consequences of oxidative stress are unlikely to be cell-type neutral. Parvalbumin-positive interneurons and oligodendrocyte lineage cells are more vulnerable because of their high metabolic load, limited antioxidant buffering capacity, and lipid/iron-related susceptibility, thereby providing a mechanistic bridge to excitation-inhibition imbalance, myelin abnormalities, and reduced circuit synchrony. Microglial redox-inflammatory signaling may further exacerbate these processes. On the basis of this framework, we argue that the key for future research is not to continue demonstrating the universality of oxidative stress, but to improve the translational efficiency. Biomarker-guided stratification, stage-sensitive study designs, and cell-type-informed therapeutic strategies may therefore provide a more productive path toward redox-targeted interventions in schizophrenia.\n\nID: 42435423\nTitle: Targeted Degradation of STING by a Neutrophil Membrane-Coated Nanoplatform Suppresses Microglial Pyroptosis After Subarachnoid Hemorrhage.\nAbstract: Subarachnoid hemorrhage (SAH) is a life-threatening cerebrovascular disease in which neuroinflammation and neuronal death critically contribute to poor outcomes. Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH. This work establishes a novel biomimetic nanomedicine strategy for SAH therapy and opens new avenues for treating neuroinflammation-related disorders.\n\nID: 42427666\nTitle: Anatomical determinants of DTI-ALPS: effects of ROI definition, ventricular morphology, and periventricular deformation.\nAbstract: The diffusion tensor image analysis along the perivascular space (DTI-ALPS) index is increasingly used as a non-invasive MRI biomarker of glymphatic and perivascular function, yet the anatomical validity and measurement stability of the metric remain incompletely characterised. Using diffusion MRI data from 850 healthy young adults and 150 healthy ageing participants from the Human Connectome Project, I systematically evaluated the influence of region-of-interest (ROI) placement and ventricular anatomy on ALPS measurements. Reference ALPS implementations demonstrated substantial hemispheric variability, with a median left-right difference of 12.5% and marked asymmetry in the underlying numerator and denominator tensor components. A two-stage optimisation framework incorporating fibre-pool alignment, hemispheric symmetry, component stability, and directional purity identified anatomically improved ROI configurations that significantly increased fibre specificity and reduced measurement variability in independent validation cohorts. Despite these improvements, residual hemispheric asymmetry persisted, suggesting an intrinsic anatomical contribution to ALPS variability. In the healthy ageing cohort, ventricular volume emerged as the strongest predictor of ALPS, explaining substantially more variance than chronological age. Voxel-wise deformation-based morphometry demonstrated that lower ALPS values were associated with ventricular and periventricular expansion, while optimisation increased coupling between ALPS and ventricular anatomy. Collectively, these findings indicate that ALPS measurements are strongly influenced by ROI definition, ventricular morphology, and surrounding periventricular tissue architecture. Rather than functioning as a direct measure of glymphatic transport in isolation, ALPS appears to represent a composite anatomical diffusion biomarker shaped by both methodological implementation and underlying neuroanatomy. These results provide a framework for improving methodological standardisation and interpretation of ALPS measurements in future neuroimaging studies.\n\nID: 42422186\nTitle: Mechanopriming by vascular stiffness and phenotypic reprogramming by disturbed flow: mechanobiology and clinical translation in atherosclerosis.\nAbstract: Atherosclerosis exhibits a distinct focal distribution at arterial bifurcations and curvatures, underscoring that systemic risk factors alone are insufficient to fully elucidate its pathogenesis. The coupling of local fluid shear stress-particularly disturbed flow (DF) and oscillatory shear stress (OSS)-with vascular wall stiffness constitutes the core mechanical driver of site-specific plaque progression. This narrative review systematically elucidates the cutting-edge molecular mechanisms of vascular wall-mediated \"mechanopriming\" and endothelial mechanotransduction. We highlight how the Piezo1 ion channel and the 5-HT1B receptor act as \"coincidence detectors,\" precisely integrating fluid shear stress and matrix stiffness signals to subsequently activate central signaling hubs such as YAP and c-REL. The dysregulation of these mechanopathways not only triggers pathological reprogramming of endothelial cells-including cGAS-STING-mediated deep senescence, NLRP3-driven pyroptosis, and endothelial-to-mesenchymal transition (EndoMT)-but also impairs RBPJ-epigenetically regulated macrophage efferocytosis and drives pathological matrix remodeling by smooth muscle cells and fibroblasts via complex transcellular communication networks. Clinically, the fusion of multimodal imaging with computational fluid dynamics (CFD), alongside emerging ultrafast ultrasound vector flow imaging, has pioneered novel avenues for the high-fidelity in vivo quantification of wall shear stress (WSS). Finally, we critically evaluate current research limitations and prospectively discuss frontier shear stress-targeted therapeutic strategies-such as \"mechanodrugs,\" biomimetic nanodelivery, and hemodynamic stent optimization-proposing a novel precision cardiovascular medicine framework that formally incorporates localized hemodynamic parameters into established clinical risk stratification algorithms like the ASCVD and SCORE2 models.\n\nID: 42421497\nTitle: Emerging viral infections: role of flavivirus NS1-mediated rewiring of PRR signaling.\nAbstract: Flaviviruses, including Dengue, West Nile, Zika, and Japanese encephalitis viruses, are arthropod-borne RNA viruses that pose an increasing global health threat. This review summarizes the role of nonstructural protein 1 (NS1), a multifunctional glycoprotein found in intracellular and secreted forms, as a key regulator of innate immunity. NS1 modulates several pattern recognition receptor pathways, including TLRs, RLRs, SR-B1-related mechanisms, and inflammasome platforms, thereby altering cytokine and interferon responses. Its effects are virus- and context-dependent. WNV NS1 inhibits TLR3/TRIF signaling, reducing IRF3 activation, type I interferon production, and interferon-stimulated gene expression. In contrast, DENV NS1 is linked to inflammatory signaling, particularly through TLR4. At the cytosolic level, NS1 from DENV, WNV, and ZIKV disrupts RIG-I/MDA5-MAVS signaling and weakens IFN-\u03b2 induction. NS1 also affects inflammasome pathways: DENV promotes IL-1\u03b2 release through a CD14-dependent mechanism, ZIKV suppresses cGAS-mediated antiviral signaling, and JEV promotes NLRP3 inflammasome assembly. Overall, NS1 selectively dampens interferon-mediated antiviral defenses while sustaining or enhancing inflammation, contributing to endothelial dysfunction, neuroinflammation, and severe disease.\n\nID: 42421041\nTitle: Advances in electroacupuncture for perioperative neurocognitive disorders: mechanisms and clinical evidence.\nAbstract: Perioperative neurocognitive disorders (PND), including postoperative delirium, delayed neurocognitive recovery, and postoperative cognitive dysfunction, are common complications in older surgical patients and are associated with impaired recovery, reduced quality of life, and increased postoperative morbidity. Current management remains largely supportive and preventive, and effective targeted therapies are still lacking. Electroacupuncture (EA), as a minimally invasive neuromodulatory intervention, has attracted increasing attention because of its potential multi-target regulatory effects. This review summarizes current mechanistic and clinical evidence regarding EA for PND. Preclinical studies suggest that EA may modulate several interacting pathological processes, including neuroinflammation, oxidative stress, autophagy dysfunction, ferroptosis, mitochondrial injury, microbiota-gut-brain axis dysregulation, and hippocampal synaptic plasticity. Recent PND/POCD animal studies further support EA-related regulation of NLRP3 inflammasome activation, cGAS-STING signaling, SIRT1/NRF2/GPX4-mediated ferroptosis, AMPK/SIRT1/FOXO1/PINK1/Parkin-related autophagy pathways, and MAPK-related synaptic plasticity. Clinical studies and meta-analyses suggest that EA and related acupoint-based electrical stimulation techniques may reduce early postoperative cognitive decline and improve short-term cognitive outcomes in older surgical patients. However, the overall evidence remains limited by heterogeneous stimulation protocols, variable acupoint prescriptions, incomplete blinding, short follow-up, and reliance on cognitive screening scales. Several proposed mechanisms are still partly inferred from non-PND models. Future studies should use standardized EA protocols, clinically relevant PND models, dynamic mechanistic assessments, and adequately powered sham-controlled trials to clarify the therapeutic role of EA in PND.\n\nID: 42411487\nTitle: The Role of Hippocampal Microglial cGAS-STING Signaling Pathway in Postoperative Cognitive Dysfunction in Diabetic Mice.\nAbstract: This study aimed to determine whether activation of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway within hippocampal microglia contributes to postoperative cognitive dysfunction (POCD) in a diabetic mouse model. Diabetes was induced using a high-fat, high-sugar (HFHS) diet combined with streptozotocin (STZ). Diabetes was induced in C57BL/6J mice using an HFHS diet followed by STZ. POCD was modeled via tibial fracture surgery under general anesthesia. Cognitive function was assessed using the Open Field Test, Y-maze, and contextual fear conditioning. cGAS-STING pathway activation was evaluated by western blot for cGAS and STING expression. Microglial activation was assessed by co-localization of Iba-1 and CD68 by immunofluorescence, and the co-localization of STING with Iba-1 in the hippocampus was examined by immunofluorescence. Hippocampal neuroinflammation was quantified by enzyme-linked immunosorbent assay (ELISA) for interleukin-1beta (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1). Neuronal injury and apoptosis were evaluated by Nissl staining and western blot for cleaved caspase-3. Compared to non-diabetic controls, diabetic mice exhibited cognitive impairments, which were more pronounced in those that underwent surgery. This was accompanied by significant hippocampal neuronal loss, upregulated cleaved caspase-3 expression, and elevated IL-1\u03b2 and TNF-\u03b1 levels. Furthermore, diabetic mice that underwent surgery displayed increased expression of microglial activation markers (Iba-1 and CD68) and evidence of cGAS-STING pathway activation in the hippocampus. Immunofluorescence co-localization experiments further suggested a predominant association of this pathway with the microglial marker Iba-1. These findings suggest that surgery-associated overactivation of the microglial cGAS-STING pathway in the hippocampus may exacerbate neuroinflammation and neuronal injury, thereby contributing to cognitive decline in diabetic mice.\n\nID: 42406535\nTitle: Fatty Acid Binding Protein 5 Mediates Astrocytic Pyroptosis and Neuroinflammation in Epilepsy via cGAS/STING Pathway.\nAbstract: Pyroptosis is an inflammatory type of programmed cell death that may contribute to epilepsy initiation and progression through neuroinflammation. Fatty acid binding protein 5 (FABP5), a lipid chaperone, has been implicated in chronic inflammation. However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells. Deletion of astrocytic Fabp5 significantly attenuated pyroptosis, neuronal loss, and seizure activity in epilepsy. Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis. Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Pharmacological inhibition of mitochondrial fatty acid import recapitulated these protective effects. In contrast, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. Collectively, these findings revealed the regulatory role of FABP5-cGAS-STING-pyroptosis axis in the progression of epilepsy and highlighted the promising potential of astrocytic FABP5 as a therapeutic target for epilepsy.\n\nID: 42404802\nTitle: Region-specific features of early glial activation and Aquaporin-4 dysregulation in conditional mouse models of TDP-43 proteinopathies.\nAbstract: Aggregation and cytoplasmic mislocalization of TDP-43 are key features of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Neuroinflammatory processes mediated by glial cells play crucial roles in the pathophysiology of these and other diseases, defined as TDP-43 proteinopathies. Here, we characterized region-specific glial activation in two conditional mouse models: hTDP-43-WT (overexpressing nuclear wild-type human TDP-43) and hTDP-43-\u0394NLS (expressing cytoplasmic TDP-43 with altered nuclear localization signal) following 1 month of transgene expression. Immunofluorescence analysis revealed distinct patterns of microglial activation across brain regions. hTDP-43-WT mice exhibited significant microgliosis in motor (MC) and somatosensory (SSC) cortices and hippocampal dentate gyrus (DG) with pronounced morphological alterations (i.e. increased soma size). Sholl analysis demonstrated reduced branching length and complexity in MC, SSC, and hippocampal subfields. hTDP-43-\u0394NLS mice displayed more pronounced microglial activation in hippocampal regions (CA1, DG) compared to cortical areas, with significant increases in microglial density. Additionally, we observed region-specific cortical astrocytosis in both models, suggesting coordinated glial reactivity. hTDP-43-\u0394NLS mice showed decreased polarization of astrocytic water channel Aquaporin-4 (AQP4) around vascular structures in SSC and hippocampal CA1/DG. The changes in AQP4 localization, which is critical for glymphatic function, support the hypothesis that this waste clearance system for the brain is altered in TDP-43 proteinopathies. These findings demonstrate that these different animal models of ALS/FTD induce distinct neuroinflammatory signatures, potentially contributing to the region-specific vulnerability observed in these diseases. Our data provide insights into early glial-mediated pathogenic mechanisms that could guide targeted therapeutic strategies for TDP-43 proteinopathies.\n\nID: 42401926\nTitle: Targeting the cGAS-STING pathway alleviates neuroinflammation and cognitive impairment induced by chronic infection of Toxoplasma gondii.\nAbstract: Chronic infection of Toxoplasma gondii has been established as a contributor to cognitive impairment via inducing sustained neuroinflammation and synaptic damage. However, the underlying mechanisms remain poorly understood. As a key regulator of both neuroinflammation and cellular senescence, Cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is implicated in pathogenesis induced by T. gondii infection. Here, we found that cGAS-STING pathway was activated in the cerebral cortex of mouse chronically infected with T. gondii, as indicated by the elevated protein levels of cGAS and STING, and increased phosphorylation of TBK1 and IRF3. Pharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage. Moreover, chronic T. gondii infection was shown to trigger senescence characterized by increased expression of senescence markers P16, P21 and P53, and senescence-associated secretory phenotypes (SASPs), including Il-1\u03b2, Il-6, Tnf-\u03b1, Cxcl1, Cxcl10 and Mmp9. In addition, elevated expression of \u03b2-galactosidase, a senescence marker, was predominantly observed in neurons compared to microglia and astrocytes, indicating a primary role for neurons in infection-associated senescence. Notably, these phenotypes of senescence were rescued by inhibition of the cGAS-STING pathway. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases.\n\nID: 42483955\nTitle: An Insight into the cGAS-STING Pathway Modulation by Metal Complexes to Initiate Immunogenic Cell Death in Cancer.\nAbstract: The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is a central regulator of antitumor immunity, capable of converting immunologically \"cold\" tumors into inflamed, immune-responsive states. Cyclic dinucleotide (CDN) agonists have clinically validated the impact of targeting this axis but are limited by poor pharmacokinetics, limited tumor penetration, and delivery challenges. Non-CDN based small-molecule modulators such as MSA-2 and amidobenzimidazole (ABZI) directly modulate cGAS-STING signaling. Beyond direct receptor agonism, coupling with metals offer platforms with complementary strategies to engage and amplify cGAS-STING signaling. Complexes incorporating platinum, ruthenium, iridium, rhodium, gold, copper, manganese, or zinc exploit redox activity, coordination versatility, and photophysical properties to induce nuclear or mitochondrial DNA stress, disrupt organelle homeostasis, and promote immunogenic cell death. By coupling STING activation to ferroptosis, pyroptosis, or cuproptosis, these complexes form the foundation of self-emerging design principles with elaborate mechanistic insights, and translational challenges shaping immune modulation for therapeutics.\n\nID: 42482991\nTitle: Targeting innate immunity to overcome immune evasion in HPV-associated cancers.\nAbstract: Human papillomavirus (HPV)-associated cancers provide a unique model for understanding the paradox of viral antigenicity and tumor immune escape. Although viral oncoproteins such as E6 and E7 generate non-self antigens, many HPV-associated tumors persist under immune pressure and show heterogeneous responses to immune checkpoint blockade. This discrepancy reflects a process in which persistent HPV infection and malignant transformation remodel innate immune sensing, interferon (IFN) signaling, antigen presentation, and the tumor microenvironment. These changes impair dendritic cell activation and cytotoxic immune priming while promoting chronic inflammation, myeloid polarization, T-cell exhaustion, and PD-1/PD-L1-mediated adaptive immune resistance. In this review, we discuss how HPV-associated cancers subvert antiviral innate immunity and how these processes contribute to immune evasion. We further highlight therapeutic strategies aimed at restoring antiviral antitumor immunity, including immune checkpoint blockade, STING agonists, therapeutic HPV vaccines, radiotherapy-based combinations, TGF-\u03b2 pathway inhibition, and biomarker-guided treatment approaches. Understanding the links among viral pathogenesis, innate immune remodeling, and checkpoint evasion may support more rational immunotherapy combinations for HPV-associated malignancies.\n\nID: 42482188\nTitle: Radiotherapy and tertiary lymphoid structures: balancing immune activation and immune damage in cancer immunotherapy.\nAbstract: Cancer immunotherapy, exemplified by immune checkpoint blockade (ICB), remains strongly influenced by the pre-existing immune organization of the tumor microenvironment. Tertiary lymphoid structures (TLSs) are ectopic lymphoid aggregates whose density, maturation state, and spatial localization correlate with clinical prognosis and ICB response across several malignancies. Radiotherapy (RT) can reshape this immune context in opposing directions. By inducing immunogenic cell death, antigen release, cGAS-STING/type I interferon signaling, vascular remodeling, and lymphocyte recruitment, RT can create conditions that support TLS-associated antitumor immunity in selected settings. Conversely, high-dose or large-volume irradiation, poorly timed nodal exposure, and collateral injury to lymphocytes, tumor-draining lymph nodes, stromal scaffolds, and high endothelial venules can disrupt established TLSs or prevent their maturation. This review summarizes current evidence on the bidirectional relationship between RT and TLS biology, differentiating validated mechanisms from indirect evidence and hypothesis-generating translational concepts. We expound on how dose, fractionation, timing, irradiated volume, nodal management and radiation modality may influence antigen presentation, lymphocyte availability, and local immune architecture. Potential strategies such as lymph-node-aware planning, proton or heavy-ion therapy, FLASH RT, vascular normalization, STING or LT\u03b2R agonism, and ICB combinations are evaluated as investigational approaches rather than established TLS-directed clinical interventions. Future studies should evaluate whether optimized RT regimens can preserve or promote the functional maturation of TLSs, integrating paired tissue biopsies, spatial transcriptomics, advanced imaging, and circulating biomarkers to definitively correlate TLS remodeling with clinical outcomes.\n\nID: 42482103\nTitle: Caloric restriction enhances radiosensitivity of colorectal tumors through the cGAS-STING pathway activation.\nAbstract: Although radiotherapy is an important clinical option for colorectal cancer, its efficacy is limited by intrinsic tumor radioresistance and radiation-induced toxicity in surrounding normal tissues. This study investigated the radiosensitizing effects of either 7-day 30% caloric restriction (CR) or 24-hour fasting in a murine model bearing CT-26 colorectal tumor and explored the underlying mechanisms. CR and fasting pretreatment enhanced irradiation-induced tumor apoptosis, mitochondrial dysfunction, and cytosolic DNA stress, leading to activation of the cyclic GMP-AMP synthase/stimulator of interferon gene (cGAS-STING) pathway, increased infiltration of tumor killing-associated CD8\u2009+\u2009cytotoxic T lymphocytes, and modulation of macrophage polarization toward an antitumor phenotype. In addition, CR and fasting further suppressed the expression of glycolysis and lipid metabolism related proteins in the tumor microenvironment upon radiation exposure. By contrast, CR and fasting protected normal intestinal tissue from irradiation-induced damage. These findings were validated in vitro using CT-26 and normal small intestinal epithelial cells (IEC-6) cultured under medium with or without glucose. The critical role of the cGAS-STING pathway in enhancing radiosensitivity was confirmed through STING siRNA-mediated knockdown, combined with pharmacological intervention using the STING agonist MSA-2 and inhibitor H-151. In conclusion, our findings indicate that CR and fasting may increase the radiosensitivity of colorectal tumors, while reducing radiation injury to normal intestinal tissue.\n\nID: 42482039\nTitle: DRP1 lysine 616 lactylation exacerbates cerebral ischemia-reperfusion injury by activating the STING inflammatory pathway.\nAbstract: Ischemia-hypoxia-induced inflammation and glycolysis are linked to the severity of cerebral ischemia-reperfusion injury (CIRI), but the mechanisms are unclear. Current research suggests that the inflammatory response of immune cells activated by STING is a key regulatory molecule in cellular inflammatory damage. However, the specific mechanisms underlying STING-mediated CIRI inflammatory responses remain unclear. This study found that STING expression was specifically elevated in microglia in the damaged side of the hippocampus in CIRI model mice, and this elevation was positively correlated with the severity of CIRI. Our previous research indicated that the dynamic process of mitochondrial fusion and fission is closely associated with CIRI. Building on this, we integrated glycolysis, mitochondrial fission, and the STING inflammatory pathway. Mechanistically, our data suggest that DRP1 K616 is a critical candidate site involved in DRP1 lactylation-associated regulation, which promotes STING pathway activation and contributes to the progression of CIRI. In conclusion, our findings offer substantial evidence that lactate-driven DRP1-mediated mitochondrial fission facilitates the involvement of the STING inflammatory pathway in CIRI. These results suggest that modulating lactate metabolism may serve as a crucial upstream strategy for therapeutic intervention in CIRI.\n\nID: 42478239\nTitle: Synergistic Mechanisms and Clinical Progress of Radionuclide Therapy Combined with Immune Checkpoint Inhibitors in Colorectal Cancer.\nAbstract: Background: Radionuclide therapy (RNT) and immune checkpoint inhibitors (ICIs) show mechanistic synergy in colorectal cancer (CRC), but clinical evidence remains limited.Objective: To summarize biological rationale, translational mechanisms, and current clinical evidence supporting RNT-ICI combinations in CRC.Methods: Narrative translational review integrating preclinical studies, radionuclide therapy literature, and CRC radiotherapy-ICI clinical trials.Results: ICIs are effective mainly in MSI-H/dMMR CRC, whereas MSS/pMMR tumors remain resistant. RNT-particularly Y-90 radioembolization-may induce immunogenic cell death, cGAS-STING activation, type I interferon signaling, and stromal remodeling. A pilot clinical study of Y-90 plus dual ICIs demonstrated feasibility and safety but limited efficacy. Evidence from EBRT-ICI CRC studies supports radiation-induced immune priming but is not directly transferable to RNT.Conclusion: RNT-ICI combinations are biologically plausible but not yet clinically validated. Future progress requires biomarker-driven, dosimetry-informed, and liver-dominant trial designs.\n\nID: 42476286\nTitle: Multifunctional Nano-vaccines Integrating Lipid-conjugated Tumor Antigens with TLR/STING Agonists Enhance Cancer Immunotherapy.\nAbstract: Although there are several ongoing clinical trials using neoantigen peptide-based cancer vaccines, challenges still exist to implement in clinical approval such as poor antigen stability, inefficient delivery, and inadequate immune activation. To address these limitations, we developed a polymer-based polyvalent peptide and adjuvant (SPPA) that co-delivers lipid-conjugated tumor-specific peptides with Toll-like receptor 7/8 (3M-052) and a STING (2'3'-cGAMP) agonist. This nanoplatform enables efficient peptide encapsulation, sustained release, and targeted delivery to antigen-presenting cells (APCs), thereby enhancing both innate and adaptive immune responses. We synthesized and characterized a library of lipid-conjugated tumor-associated and neoantigenic peptides. In vitro, SPPA significantly upregulated pro-inflammatory genes and cytokine secretion, confirming robust innate immune activation and demonstrated effective cellular uptake and lymphatic trafficking. In vivo, SPPA alone or in combination with anti-PD-1 antibody (\u03b1PD-1) elicited strong cytotoxic T lymphocyte (CTL) responses and inhibited tumor growth in four aggressive syngeneic mouse models: Triple-negative breast cancer (4T1), HER2+ breast cancer (TUBO), lung carcinoma (LLC1), and renal cell carcinoma (RENCA). The combination therapy led to pronounced tumor growth inhibition, survival benefit, and immune cell infiltration, including elevated CD8+IFN-\u03b3+ T cells and M1 macrophages, and reduced regulatory T cells and MDSCs. Spatial transcriptomics revealed localized transcriptional reprogramming, with downregulation of extracellular matrix genes and activation of inflammatory pathways. Collectively, these findings establish SPPA as a potent and versatile nanovaccine platform capable of inducing durable antitumor immunity, especially when combined with immune checkpoint blockade. This approach offers strong translational potential for personalized immunotherapy across diverse solid tumor types.\n\nID: 42474944\nTitle: Mitochondrial stress-induced cuproptosis: a metabolic bridge to reprogramming the GBM immune microenvironment.\nAbstract: Glioblastoma (GBM) remains the most lethal primary brain malignancy, characterized by profound metabolic heterogeneity and an immunosuppressive tumor immune microenvironment (TIME) that severely limits the efficacy of immune checkpoint blockade. While cuproptosis has recently been defined as a distinct form of regulated cell death driven by copper-induced mitochondrial proteotoxicity, its non-cell-autonomous roles in remodeling the immune landscape remain poorly understood. This review synthesizes emerging evidence to position cuproptosis not merely as a metabolic collapse, but as a potent driver of immunogenic cell death (ICD). We propose a potential \"metabolic-immune\" signaling axis wherein copper-triggered aggregation of lipoylated TCA cycle enzymes leads to mitochondrial membrane rupture and the subsequent leakage of mitochondrial DNA (mtDNA) into the cytosol. This danger signal is sensed by the cyclic GMP-AMP synthase (cGAS), activating the STING pathway to stimulate type I interferon production. We discuss how this cascade orchestrates a systemic immune response, including the recruitment of cytotoxic CD8\u2009+\u2009T cells and the repolarization of tumor-associated macrophages from a pro-tumor M2 to an anti-tumor M1 phenotype. Furthermore, we highlight the translational potential of copper ionophores and bioengineered nanomedicines as next generation immunomodulators. By integrating copper metabolism with innate immunity, this review provides a strategic roadmap for exploiting mitochondrial stress to reverse immune exclusion and overcome therapy resistance in GBM.\n\nID: 42473606\nTitle: Mitochondria-targeted MXene-based nanozymes promote mitophagy and inhibit mtDNA-triggered cGAS/STING inflammation in osteoarthritis.\nAbstract: Osteoarthritis (OA) is a prevalent and debilitating joint disease driven by progressive cartilage degradation, mitochondrial dysfunction, and chronic inflammation. In this study, we introduced MS@PMXene-TK, an innovative, mitochondria-targeted nanozyme designed for cartilage repair by addressing these key pathological features. This nanozyme platform uniquely integrated a chondro-inductive peptide (SPPEPS)-loaded, polydopamine (PDA)-modified MXene core (S@PMXene) with a reactive oxygen species (ROS)-responsive thioketal-linked polyethylene glycol (PEG-TK) shell and a mitochondria-targeting peptide (MTP-131), enabling precise and responsive therapeutic intervention at the subcellular level. In vitro and in vivo analyses demonstrated that MS@PMXene-TK effectively scavenged mitochondrial ROS within chondrocytes, acting as a \"cruise missile,\" which led to restoration of mitochondrial membrane potential and promotion of mitophagy. This cascade mitigated mtDNA leakage and subsequent activation of the cGAS/STING pathway, a critical inflammatory driver in OA. Concurrently, sustained release of SPPEPS enhanced chondrogenic marker expression and extracellular matrix synthesis, while alleviating macrophage-mediated inflammatory responses, further modulating the inflammatory microenvironment. In an anterior cruciate ligament transection (ACLT)-induced OA mouse model, intra-articular administration of MS@PMXene-TK significantly improved cartilage protection and subchondral bone integrity. These findings establish the potential of this targeted, multi-modal nanozyme strategy to disrupt intertwined pathologies of oxidative stress and inflammation in OA, offering a promising avenue for OA treatment.\n\nID: 42471165\nTitle: Dual-regulation of mitophagy and cytosolic mtDNA-induced inflammation for the treatment of inflammatory bone loss.\nAbstract: Inflammatory osteoporosis, also known as \"immunoporosis,\" is a condition characterized by chronic inflammation and mitochondrial dysfunction, leading to impaired bone regeneration. Mitochondrial DNA (mtDNA) leakage activates the cGAS-STING pathway, triggering excessive inflammatory responses and hindering osteogenesis. Concurrently, defective mitophagy exacerbates mitochondrial damage, perpetuating a cycle of bone loss. This study investigated the role of the mtDNA-cGAS-STING axis in lipopolysaccharide (LPS)-induced bone marrow mesenchymal stem cells (BMSCs) dysfunction and inflammatory bone loss. We exposed BMSCs to LPS and assessed mitochondrial function, mtDNA release, and cGAS-STING activation using RT-qPCR, Western blotting, and immunofluorescence. We then engineered exosomes to co-deliver siRNA targeting STING and PINK1 mRNA, testing their effects on osteogenesis and mitochondrial homeostasis in vitro and in a mouse model of LPS-induced osteoporosis. LPS exposure resulted in mitochondrial damage, mtDNA leakage, and cGAS-STING activation, impairing osteogenic differentiation and increasing inflammatory cytokine expression. While STING inhibition reduced inflammatory signaling, it did not restore mitochondrial function, whereas PINK1 overexpression improved mitophagy and partially suppressed cGAS-STING activation. Dual regulation through siSTING/PINK1@Exo synergistically reduced mitochondrial ROS, restored membrane potential, promoted osteogenic marker expression, and enhanced mineralization in vitro. Dual-regulated exosomes significantly improved trabecular bone microarchitecture, reduced STING expression, and enhanced RUNX2 and OCN expression compared to single treatments through in vivo model. These results demonstrate that combining mitophagy activation with STING inhibition via engineered exosomes offers a promising therapeutic strategy for inflammatory osteoporosis by addressing both mitochondrial dysfunction and chronic inflammation.\n\nID: 42471059\nTitle: Nanozyme-integrated hydrogel orchestrates mitochondrial quality control to counter inflammatory and oxidative milieu during disc degeneration.\nAbstract: Intervertebral disc degeneration (IDD) is a major cause of low back pain, driven by nucleus pulposus (NP) cell dysfunction, excessive reactive oxygen species (ROS), and chronic inflammation. Current biomaterial-based strategies often fail to simultaneously address oxidative stress and inflammatory signaling in a sustained and synergistic manner. Here, we develop a thermosensitive Pluronic F127-based composite hydrogel co-delivering a tannic acid\u2011cerium nanozyme and the FPR1 antagonist HCH6-1. The hydrogel undergoes sol-gel transition at body temperature, enabling minimally invasive injection and sustained local release in the intervertebral disc. The cerium nanozyme exerts potent ROS-scavenging activity, effectively reducing intracellular ROS levels and upregulating the antioxidant protein TXNRD1. Meanwhile, HCH6-1 specifically antagonizes FPR1, thereby suppressing cGAS-STING pathway activation and suppressing downstream inflammatory cascades. Beyond direct anti-inflammatory effects, this system significantly enhances mitophagy activity in NP cells, facilitating the clearance of dysfunctional mitochondria and restoring autophagic flux. Collectively, in vitro and in vivo evidence confirms that this dual-functional hydrogel attenuates NP cell inflammation and significantly retards the progression of IDD. Thus, this injectable and biocompatible platform offers a synergistic strategy that couples nanozyme-mediated antioxidant therapy with targeted FPR1 blockade, holding substantial promise for intervertebral disc repair.\n\nID: 42470296\nTitle: Cell Selective STING-Activating Polysaccharide Immunomodulators for Cancer Therapy.\nAbstract: Activation of the stimulator of interferon genes (STING) signaling pathway represents a robust strategy to reverse tumor immunosuppressive microenvironment (TIME) for cancer therapy. However, selective STING activation and its quantitative comparison across heterogeneous cell populations remain a tremendous challenge. Herein, we engineered a type of selective STING-activating polysaccharide immunomodulators (SSAPIs) with quantitative STING activation efficiency across tumor cell, macrophage, and dendritic cell (DC). Dextran as an immune cell targeting nanocarrier was employed to improve drug delivery to macrophage and DC, and to avoid the impact of macromolecular self-assembly on drug release kinetics. The STING agonist (DMXAA) was conjugated to dextran via defined linkers to control the selectivity of STING activation in different cell populations. In vitro experiments quantitively revealed the enhanced STING activation of the ester linker SSAPI (DESX) in macrophage, while the disulfide linker SSAPI (DSSX) prompted STING activation across tumor cell and immune cell. In B16F10 and CT26 tumor-bearing mice models, DSSX exhibited much superior antitumor efficacy with six out of eight complete tumor remission by inducing broad immune responses across diverse cell populations to reprogram TIME. Collectively, this work highlights the significance of activating the STING signaling pathway across cell populations in solid tumor for cancer immunotherapy.\n\nID: 42469180\nTitle: STING Drives CD4+T Cell Differentiation via JAK-STAT Signalling in Bullous Pemphigoid.\nAbstract: Bullous pemphigoid (BP) is an autoimmune blistering disease with an increasing incidence in recent years; however, the underlying immune regulatory mechanisms remain largely unclear. As a critical signalling hub linking innate and adaptive immunity, stimulator of interferon genes (STING) has recently been implicated in the pathogenesis of various autoimmune diseases and may regulate tissue inflammation and immune homeostasis through modulation of CD4+ T cell responses. In this study, we found that STING expression was significantly increased in lesional skin tissues from patients with BP compared with healthy controls. Transcriptomic analysis further revealed that differentially expressed genes in peripheral blood CD4+ T cells from BP patients were primarily enriched in the JAK-STAT signalling pathway, T cell activation and differentiation, and type I interferon (IFN-I)-related pathways. Pharmacological inhibition of STING markedly attenuated the aberrant activation of these signalling pathways. Moreover, qRT-PCR analysis confirmed that the mRNA levels of STING1, JAK1, and CXCR5 were significantly elevated in BP patients, whereas treatment with the STING inhibitor C176 suppressed the expression of these molecules. Collectively, our findings suggest that STING may contribute to BP immunopathogenesis by regulating the JAK-STAT signalling axis and promoting abnormal CD4+ T cell activation and differentiation, providing new insights into the molecular mechanisms underlying BP and identifying potential therapeutic targets.\n\nID: 42468805\nTitle: Periodontitis accelerates STING-mediated bone remodeling during orthodontic tooth movement.\nAbstract: Orthodontic tooth movement (OTM) is a mechanically induced inflammatory process. Intriguingly, OTM under periodontitis conditions orchestrates a complex inflammatory microenvironment and exacerbates bone resorption. Stimulator of interferon genes (STING) is a key inflammation mediator, but its role in OTM with periodontitis was unclear. We established an OTM model in rats with ligature-induced periodontitis. In vitro, rat periodontal ligament fibroblasts (PDLFs) were subjected to compressive stress and LPS to mimic orthodontic force and periodontitis inflammation. STING was activated with agonists (cGAMP/diABZI) or inhibited with H151 or knockdown. Inflammatory responses and bone resorption were assessed. RNA sequencing and co-IP followed by LC-MS/MS were used to identify downstream signals. STING activation in PDLFs increased IL-1\u03b2 and IL-6 while reducing Runx-2 and osteogenesis. In periodontitis-OTM rats, STING, IL-1\u03b2 and IL-6 were upregulated and Runx-2 downregulated on the compression side, leading to increased alveolar bone loss that was rescued by H151. Under mechanical-inflammatory stress, activated STING triggered ER stress, and a cascade of cellular responses including increased pro-inflammatory mediators, enhanced apoptosis, altered mechano-response, and suppressed osteogenesis. Meanwhile, Annexin A2 (Anxa2) was identified as a novel STING interactor. Anxa2 knockdown mirrored STING inhibition, suppressing ER stress, inflammatory activation, apoptosis and mechano-response. Mechanistically, Anxa2 knockdown markedly reduced P65 phosphorylation and nuclear translocation, suggesting Anxa2 may serve as an intermediary linking STING to NF-\u03baB activation. STING-Anxa2 interaction was notably increased in PDLFs and in compression-side periodontal tissues under mechanical-inflammatory stress. Within an inflammatory milieu, STING activation in PDLFs is associated with ER stress, pro-inflammatory responses, apoptosis, and suppressed osteogenesis that collectively accelerate bone resorption during OTM. We identified Annexin A2 (Anxa2) as a novel STING interactor whose knockdown attenuated these responses and NF-\u03baB activation, suggesting Anxa2 as a functional intermediary in STING-mediated inflammation.\n\nID: 42468696\nTitle: Manganese overload as a previously underappreciated trigger of cellular senescence: unraveling mechanisms and therapeutic rescue by the senolytic quercetin.\nAbstract: Manganese (Mn) is an essential trace element, but excessive Mn exposure is associated with neurotoxicity and aging-related dysfunction. Whether Mn overload promotes cellular senescence and the mechanisms involved remain insufficiently defined. Here, we investigated Mn-induced senescence-associated injury using Caenorhabditis elegans and neuron-like PC12 cells. Mn exposure shortened lifespan, impaired locomotor behavior, altered dopaminergic neuronal signals, and increased senescence-associated \u03b2-galactosidase activity in C. elegans. In PC12 cells, Mn induced senescence-associated phenotypes, including reduced viability, \u03b2-galactosidase positivity, telomere attrition, p53/p21 activation, oxidative stress, mitochondrial dysfunction, DNA damage-related alterations, inflammatory responses, and stimulator of interferon genes (STING)-related signaling. Quercetin attenuated Mn-induced oxidative, mitochondrial, inflammatory, and senescence-associated changes, while STING inhibition partially alleviated cell injury and \u03b2-galactosidase positivity. These findings suggest the involvement of STING-related signaling in Mn-induced neurotoxic injury accompanied by senescence-associated changes and suggest that this process may be pharmacologically attenuated.\n\nID: 42468529\nTitle: Purine and pyrimidine-based bacterial cyclic dinucleotides egress the phagosome and activate the innate immune sensor STING.\nAbstract: Toll-like receptors (TLRs) are considered general sensors of bacterial encounters. Here, we examined whether other pattern recognition receptors are commonly activated during bacterial infection. TLR-independent interferon (IFN) responses were induced in macrophages in response to diverse bacterial encounters. Of the cytoplasmic receptor families examined, the cyclic dinucleotide (CDN) sensor STING was required for IFN responses to evolutionarily diverse bacteria. Various bacterial CDNs were present in murine tissues; these activated stimulator of interferon genes (STING) after bacteriolysis in phagolysosomes in a manner requiring two CDN transporters. Importantly, bacterial CDNs were increased in colonic biopsies from patients with inflammatory bowel disease. Systemic delivery of dead, CDN-laden bacteria promoted anti-tumor immunity in mice. Detection of diverse CDNs, including pyrimidine-based CDNs, was an evolutionarily conserved feature of STING, with distinct binding modes for purine- and pyrimidine-based CDNs. Thus, a phagocytosis-CDN-STING connection places cytoplasmic sensing as a common outcome of host-bacteria interactions that set the immune tone of a tissue, with implications for host defense.\n\nID: 42467855\nTitle: HD-tDCS Restores Perivascular AQP4 Polarization via PPAR\u03b3 Modulation to Enhance Glymphatic Clearance After Intracerebral Hemorrhage in Mice.\nAbstract: Impaired perivascular aquaporin 4 (AQP4) polarization and glymphatic dysfunction after intracerebral hemorrhage (ICH) may delay hematoma and perihematomal edema resolution. The effects of high-definition transcranial direct current stimulation (HD-tDCS) on glymphatic transport and recovery after ICH, as well as the underlying mechanisms, are investigated in a collagenase-induced mouse model. HD-tDCS (anodal stimulation, 0.1\u00a0mA, 10\u00a0min daily) significantly enhances cerebrospinal fluid influx, improves interstitial solute clearance, reduces intracerebral tracer retention, and increases drainage to the deep cervical lymph nodes, as assessed by in vivo two-photon imaging, contrast-enhanced MRI, and ex vivo tracer analysis. HD-tDCS also accelerates hematoma and edema resolution, reduces midline shift and diffusion abnormalities, and improves neurological outcomes. Mechanistically, ICH induces astrocytic proinflammatory activation together with impaired perivascular AQP4 polarization, whereas HD-tDCS upregulates peroxisome proliferator-activated receptor gamma (PPAR\u03b3), suppresses proinflammatory astrocyte activation, and restores perivascular AQP4 localization. Astrocyte-specific knockdown or pharmacologic inhibition of PPAR\u03b3 attenuates HD-tDCS-induced AQP4 repolarization, glymphatic recovery, and neurological improvement. These findings indicate that HD-tDCS promotes hematoma and edema resolution after ICH in association with PPAR\u03b3-dependent astrocyte remodeling, AQP4 repolarization, and glymphatic restoration.\n\nID: 42467313\nTitle: Disruption of macrophage migration inhibitory factor signaling induces major tumor-associated macrophage phenotypes in human M2 macrophages.\nAbstract: Tumor-associated macrophages (TAMs) primarily arise from infiltrating monocytes, yet the mechanisms guiding their differentiation remain unclear. Here, we show that human macrophages rely on autocrine macrophage migration inhibitory factor signaling to suppress p53 during M2-like transition. Disruption of this pathway led to activation of p53 and, unexpectedly, the nuclear receptor NR4A1, inducing a senescence-like state resembling interleukin (IL)-1\u03b2\u207a and IL-4 Induced 1 (IL4I1)\u207a TAM subsets observed across multiple cancers. These TAM-like macrophages exhibited a transcriptional program driven by NR4A1, similar to that induced in IL-1\u03b2\u207a TAMs by the combined action of tumor necrosis factor \u03b1 (TNF) and the cyclooxygenase-2-dependent arachidonic acid (AA) metabolite prostaglandin E2. They also upregulated the AA-selective acyl-CoA synthase ACSL4, which promoted cell survival and restrained IL-1\u03b2 release despite elevated IL1B expression. This effect was mediated through induction of the IL4I1\u207a TAM marker CD38, which drove the production of IL-10. Mechanistically, ACSL4 preserved the homeostatic function of stimulator of interferon genes (STING). Loss of ACSL4 resulted in extensive macrophage death and converted STING from a homeostatic regulator into a driver of IL-1 cytokine release. Finally, we show that the CDK4/6 inhibitor abemaciclib repolarized TAM-like macrophages toward a more inflammatory phenotype through off-target inhibition of ACSL4. Abemaciclib enhanced inflammatory signaling by modulating ectodomain shedding, increasing TNF while reducing the release of its natural antagonist, TNF receptor II. Together, these findings clarify mechanisms underlying scRNA-seq-defined TAM phenotypes, identify ACSL4 as a potential therapeutic target, and reveal how abemaciclib can promote inflammatory responses in cancer patients.\n\nID: 42465772\nTitle: Molecular signaling in coinfection: how M. tuberculosis and respiratory viruses rewire host immunity and alter TB outcomes.\nAbstract: Tuberculosis (TB) caused by Mycobacterium tuberculosis (M. tuberculosis) and respiratory viral infections remain major, intersecting global health challenges, and their co-occurrence imposes a disproportionate burden in high-HIV/high-TB regions such as sub-Saharan Africa. Coinfection biology is heterogeneous and dynamic, driven by viral diversity including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza A/B, Respiratory Syncytial Virus (RSV), parainfluenza, metapneumovirus, rhinovirus, adenovirus, and bocavirus, and by the underlying TB stage, from latent and subclinical to active and reactivation disease. Innate sensing pathways, such as Toll-like receptors (TLR), retinoic acid-inducible gene I (RIG-I), and cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING), converge during coinfection, reshaping type I interferon (IFN-I), Nuclear Factor kappa-light-chain-enhancer of activated B cells (NF-\u03baB), and AP-1-driven responses and triggering a network of autocrine and paracrine signaling that reprograms macrophages, dendritic cells, and T-cell subsets. This immune rewiring alters granuloma equilibrium through suppressed Th1/IFN-\u03b3 coordination, exaggerated Th17/IL-17-driven neutrophilia, and regulatory T-cell or IL-10-mediated dampening, which together destabilize macrophage activation and tissue architecture. Oxidative stress, mitochondrial dysfunction, and Matrix Metalloproteinases (MMP)-driven matrix remodeling further integrate with these pathways, converting inflammatory signals into epithelial damage, cavitation, and fibrosis. Consequently, disease outcomes depend critically on timing, viral burden, pathogen order, host immune endotype, and TB stage, such that the same virus can either preserve containment or drive progression depending on the local immunological context. Importantly, the effects of respiratory viral coinfection vary across the TB disease continuum, influencing early granuloma formation, latent infection, reactivation risk, and established disease through distinct immunological mechanisms. Host-directed therapies (HDT) targeting interferon, IL-1, TNF, inflammasome, or metabolic checkpoints hold mechanistic promise but exhibit variable clinical translation, underscoring the need for precision approaches that integrate stage- and endotype-specific biomarkers. This narrative review proposes an integrated systems framework that links viral sensing, immune rewiring, granuloma biology, and tissue-remodeling to TB-respiratory virus coinfection, and emphasizes how timing-aware, biomarker-guided strategies can refine diagnosis, clinical management, prognosis, and vaccine design in vulnerable populations.\n\nID: 42465768\nTitle: Gut-lung axis in radiation-induced lung injury: mechanisms and interventions.\nAbstract: Radiation-induced lung injury (RILI) constrains thoracic radiotherapy dosing and includes acute radiation pneumonitis (RP) and chronic radiation-induced pulmonary fibrosis (RPF). This narrative review explores the gut-lung microbiota axis in RILI, synthesizing evidence from preclinical models, clinical cohorts (N\u00a0=\u00a052-89), and randomized controlled trials (RCTs). Radiotherapy induces gut dysbiosis, barrier breakdown, and metabolite changes [e.g., short-chain fatty acid (SCFA) and desaminotyrosine (DAT) depletion], promoting inflammation and fibrosis via pathways such as Toll-like receptor 4/nuclear factor kappa B (TLR4/NF-\u03baB), TGF-\u03b2/Smad, sphingosine-1-phosphate (S1P)-S1PR, and cGAS-STING in animal studies. Inter-species microbial variations hinder translation, while lung microbiota shifts remain nascent. In non-small cell lung cancer cohorts, lower gut microbiota stability (a marker of dysbiosis) is associated with an increased risk of grade \u22652 RP (multivariable-adjusted models, p < 0.05), with higher baseline Faecalibacterium abundance conferring protection; however, causality remains unproven due to antibiotic confounding. Mechanisms involve lipopolysaccharide (LPS) translocation, interleukin 25 (IL-25)/S1P-driven type 2 innate lymphoid cell (ILC2) migration, regulatory T cell/T helper 17 cell (Treg/Th17) imbalance, and extracellular vesicle (EV) signaling, with biomarkers such as 16S rRNA sequencing and EV-miRNAs (e.g., miR-486-5p). Artificial intelligence models predict RP with 75% accuracy. Phase-specific interventions, such as pre-radiotherapy gut microbiota monitoring, intra-radiotherapy SCFA supplementation, subacute DAT modulation, and RPF-targeted EV therapies, have been explored in preliminary pilot studies [for example, one small study reported approximately 12% FEV1 improvement following fecal microbiota transplantation (FMT)]. Future large-scale, stratified RCTs that properly account for antibiotics, chemotherapy, and immunotherapy are required to establish causality beyond the current largely associative clinical evidence. The integration of immunotherapy and proton therapy in such trials may help clarify gut-lung interactions, including any microbiota-preserving effects of proton therapy; the role of the lung microbiota in fibrosis remains preliminary.\n\nID: 42462870\nTitle: LKB1/ AMPK deficiency aggravates mitochondrial DNA leakage via mTOR-dependent mitophagy damage in liver injury sensitized by trichloroethylene.\nAbstract: Occupational medicamentosa-like dermatitis induced by trichloroethylene (OMDT) is a severe systemic allergic disease, often accompanied by acute liver injury. However, the underlying mechanisms linking metabolic disorders and immune damage remain unclear. In a TCE-sensitized mouse model, we demonstrated that TCE sensitization inhibited LKB1/AMPK/mTOR signaling pathway (LKB1 overexpression, AICAR, rapamycin) or autophagy (3-MA) in hepatocytes, resulting in defective mitophagy. This mitochondrial dysfunction leads to leakage of mitochondrial DNA (mtDNA) into the cytoplasm, where mtDNA acts as a damage-associated molecular pattern (DAMP) to activate the cGAS-STING pathway, driving the production of proinflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and exacerbating liver inflammation. Restoration of LKB1/AMPK signaling or inhibition of mTOR rescued mitophagi, reduced mitochondrial DNA leakage, inhibited cGAS-STING activation, and alleviated liver pathology, while inhibition of autophagy alone recapitulated the TCE-induced phenotype. Taken together, our findings demonstrate that failure of TCE via LKB1/AMPK/mTOR mediated mitophagy destroys hepatocyte homeostasis, leading to mtDNA-driven cGAS-STING activation and immune-mediated liver injury in the pathogenesis of OMDT, thus providing a potential therapeutic target for OMDT-related liver injury.\n\nID: 42462139\nTitle: Elevated CHAF1A suppresses type I interferon production and causes immunotherapy resistance in esophageal squamous cell carcinoma.\nAbstract: In esophageal squamous cell carcinoma (ESCC), chemoradiotherapy potentiates the effects of immune checkpoint inhibitors (ICIs) by activating the tumor-intrinsic innate immune response. However, ESCC cells frequently suppress this activation, which contributes to the high rates of immunotherapy resistance (70-80%) observed clinically. Thus, identifying intracellular suppressors of this innate immune response remains an unmet critical need. Herein, through multi-omic analyses, we identify the chromatin assembly factor CHAF1A as a suppressor of the tumor-intrinsic innate immune response in ESCC. We found that CHAF1A was overexpressed in ESCC and negatively correlated with type I interferon production and CD8+ T-cell infiltration. Mechanistically, CHAF1A maintained heterochromatin silencing mediated by H3K9me3, thereby repressing endogenous retroviruses (ERVs). This suppression prevented the accumulation of double-stranded RNA (dsRNA) and the subsequent activation of the MAVS-IRF3 signaling pathway. Concurrently, CHAF1A preserved genomic stability, limiting the release of double-stranded DNA (dsDNA) and activation of the cGAS-STING pathway. Loss of CHAF1A potentiated the response to immunotherapy through the coordinated activation of these dual pathways. We then performed a small-molecule compound screen and identified a CHAF1A inhibitor, Baimaside, which enhanced the effect of anti-PD-1 therapy to augment antitumor immunity. Collectively, these data indicate that CHAF1A represents a potential therapeutic target for sensitizing ESCC to immunotherapy and provide a potential combination strategy for reversing immunotherapy resistance.\n\nID: 42459658\nTitle: The mitochondrial logic of inflammaging: how energy imbalance drives fibroblast SASP and tissue-specific aging.\nAbstract: The conversion of metabolic disequilibrium into chronic inflammatory signaling represents a central and actively investigated question in ageing biology. Among stromal cells, fibroblasts are key effectors of tissue remodeling and inflammation, acquiring a senescence-associated secretory phenotype (SASP) that sustains age-related pathology. Here, we delineate a mechanistic framework in which disruption of energy homeostasis drives mitochondrial dysfunction, innate immune activation, and SASP secretion. Mitochondria act as metabolic sentinels that sense energetic stress through altered AMP/ATP and NAD+/NADH ratios, leading to the generation of mitochondrial danger signals-reactive oxygen species (mtROS) and mitochondrial DNA (mtDNA). These signals converge on canonical immune pathways, including the cGAS-STING axis, NLRP3 inflammasome, and NF-\u03baB signaling, thereby converting metabolic distress into persistent pro-inflammatory output. Using periodontal ligament fibroblasts as a disease-relevant model, we highlight how microbial biofilm exposure induces mitochondrial metabolic reprogramming that amplifies fibroblast SASP, promotes osteoclastogenesis, extracellular-matrix degradation, and alveolar bone resorption. At the transcriptional level, regulatory networks involving NF-\u03baB, C/EBP\u03b2, STATs, and the mTOR-AMPK hub integrate mitochondrial signals to sustain inflammatory senescence. We propose that restoring mitochondrial metabolic homeostasis serves as a highly promising strategy to break the self-perpetuating cycle in which energy imbalance triggers SASP activation, which in turn contributes to chronic inflammation. Researchers must first characterize the tissue-specific mitochondrial signatures of SASP. Subsequently, developing precise, lesion-targeted metabolic interventions will open new avenues for mitigating inflammaging and rejuvenating stromal function across ageing tissues.\n\nID: 42458463\nTitle: Discovery of XNW5004 as a novel EZH2 inhibitor that enhances anti-tumor immunity and synergizes with PD-1 blockade immunotherapy in lung adenocarcinoma.\nAbstract: Synergistic strategies are urgently needed to enhance the efficacy of immunotherapy in lung cancer. Recent evidence highlights Enhancer of zeste homolog 2 (EZH2) as a pivotal epigenetic regulator that fosters an immunosuppressive tumor microenvironment, thereby driving immunotherapy resistance. We hypothesized that EZH2 pharmacological inhibition could increase immunotherapy susceptibility. This study aimed to investigate the potential of a novel EZH2 inhibitor, XNW5004, to sensitize lung adenocarcinoma (LUAD) to programmed cell death protein 1 (PD-1) blockade. In vitro, colony formation and apoptosis assays assessed direct cytotoxicity of XNW5004 on tumor cells at 0-12 \u00b5M. A co-culture system of tumor cells and peripheral blood mononuclear cells evaluated immune-mediated killing. In vivo, immunodeficient nude mice and immunocompetent C57BL/6 mice were randomly assigned to the control, XNW5004, anti-PD1, and combination groups to assess the tumor suppressive effect. Underlying mechanisms were explored through RNA sequencing alongside comprehensive cellular and molecular assays. In vitro, pre-treating tumor cells with 1.5 \u00b5M XNW5004 enhanced their sensitivity to immune cell attack, resulting in fewer residual cells and increased apoptosis, an effect further potentiated by PD-1 blockade. In vivo, XNW5004 suppressed tumor growth in immunocompetent C57BL/6 mice but showed minimal effect in immunodeficient nude mice. Mechanistically, XNW5004 stimulated chemokine-mediated recruitment of dendritic cells and T cells into tumor sites. Additionally, it upregulated the antigen presentation molecule major histocompatibility complex class I (MHC-I), while simultaneously augmenting the expression of co-signaling molecules programmed death ligand 1(PD-L1) and intercellular adhesion molecule-1 (ICAM-1). These alterations contributed to the augmented cytotoxic activity of both CD8+ T cells and natural killer cells, as evidenced by increased interferon-\u03b3 and granzyme B. The STING-TBK1-NF-\u03baB axis functions as a pivotal regulatory signaling pathway driving these phenotype alterations. The EZH2 inhibitor XNW5004 enhances anti-tumor immunity and synergistically interacts with PD-1 blockade immunotherapy in LUAD, establishing this combinatorial approach as a promising therapeutic strategy.\n\nID: 42457929\nTitle: MGMT deficiency augments STING-mediated inflammatory responses accompanied by metabolic alterations in macrophages.\nAbstract: The cGAS-STING pathway senses cytosolic DNA derived from both pathogens and host cells and plays a central role in innate immune responses. O6-methylguanine-DNA methyltransferase (MGMT) is a DNA repair enzyme that removes alkylation-induced DNA lesions and modulates macrophage inflammatory responses. Here, we investigated the role of MGMT in macrophage responses to STING activation. Bone marrow-derived macrophages (BMMs) from Lyz2\u0394Mgmt mice produced higher levels of IL6, TNF\u03b1, and IFN\u03b2 following stimulation with the STING agonist DMXAA, accompanied by increased phosphorylation of TBK1 and IRF3. Lyz2\u0394Mgmt BMMs also exhibited increased expression of CD86, CD40, and CD120a (TNFRI), but reduced MHC class II expression. Metabolic flux analysis revealed enhanced mitochondrial oxidative respiration, increased ATP production, and greater maximal respiratory capacity, whereas glycolytic capacity remained unchanged. In addition, DMXAA-stimulated Lyz2\u0394Mgmt BMMs displayed increased \u03b3H2AX levels and reduced activation of the energy sensor AMPK and autophagy. Transcriptomic analysis further identified enrichment of pathways associated with cellular respiration. Collectively, these findings indicate that MGMT deficiency is associated with enhanced STING-induced inflammatory responses, altered cellular metabolism, and increased DNA damage in macrophages.\n\nID: 42457927\nTitle: DHRS9 generates crotonyl-CoA from butyryl-CoA to epigenetically regulate STING transcription and potentiate immune activation.\nAbstract: The stimulator of interferon genes (STING) pathway is a cornerstone of innate immunity and a promising therapeutic target for autoimmune diseases, inflammation, and cancer treatment. Lysine crotonylation, a recently discovered post-translational modification, regulates various cellular processes; however, its role in STING activation remains unclear. Here, we identified dehydrogenase/reductase (SDR family) member 9 (DHRS9) as a critical metabolic regulator of the STING signaling pathway. DHRS9 deficiency impaired activation of the\u00a0cGAS-STING pathway, suppressed antiviral immunity against HSV-1, and exacerbated viral replication. Mechanistically, DHRS9 converts butyryl-CoA into crotonyl-CoA, thereby enhancing histone crotonylation (H3K14cr and H3K18cr) at the STING promoter to drive its transcription. AAV-mediated DHRS9 delivery significantly enhances antiviral and antitumor immunity, demonstrating its robust therapeutic potential. This study reveals a metabolic-epigenetic axis that regulates STING expression, offering new therapeutic strategies for immune-related diseases.\n\nID: 42457332\nTitle: [Thymosin \u03b24 inhibits pyroptosis in BV2 microglial cells: a mechanistic study in vitro].\nAbstract: To investigate the protective effects and molecular mechanisms of thymosin \u03b24 (T\u03b24) on pyroptosis in BV2 microglial cells. BV2 cells were divided into three groups: control group (no treatment), pyroptosis group [stimulated with 1 \u03bcg/mL lipopolysaccharide (LPS) for 12 hours, followed by 10 \u03bcmol/L nigericin (Nig) treatment for 1 hour], and T\u03b24 treatment group (co-incubated with LPS and Nig, then treated with 1 \u03bcg/mL T\u03b24 for 1 hour). An in vitro sepsis-associated encephalopathy model was established by LPS and Nig co-treatment. Viability of BV2 cells was assessed by CCK-8 assay. RT-qPCR was performed to detect mRNA expression of interleukin (IL)-1\u03b2, interferon-induced protein with tetratricopeptide repeats 1 (IFIT1), and interferon-\u03b2 (IFN-\u03b2). IL-1\u03b2 levels in cell supernatants were measured by ELISA. Protein expression of NLRP3, GSDMD-N, cleaved caspase-1, phosphorylated stimulator of interferon genes (p-STING), and phosphorylated interferon regulatory factor 3 (p-IRF3) was analyzed by Western blot. Cell death rate and mitochondrial reactive oxygen species (ROS) levels were detected by flow cytometry using propidium iodide staining and MitoSOX indicator, respectively. Compared with the pyroptosis group, T\u03b24 treatment alleviated morphological damage caused by pyroptosis in BV2 cells. Intracellular mRNA expression of IL-1\u03b2, IFIT1, and IFN-\u03b2; IL-1\u03b2 concentration in supernatant; protein expression of NLRP3, GSDMD-N, cleaved caspase-1, p-STING, and p-IRF3; cell death rate; and mitochondrial ROS levels were significantly decreased (P0.05). T\u03b24 protects BV2 microglial cells against LPS and Nig-induced pyroptosis by inhibiting oxidative stress and inflammatory responses, potentially through regulation of the cGAS-STING signaling pathway. \u76ee\u7684: \u63a2\u7a76\u80f8\u817a\u7d20\u03b24\uff08thymosin beta 4, T\u03b24\uff09\u5bf9BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\u7126\u4ea1\u7684\u4fdd\u62a4\u4f5c\u7528\u53ca\u5206\u5b50\u673a\u5236\u3002\u65b9\u6cd5: \u5c06BV2\u7ec6\u80de\u5206\u4e3a\u5bf9\u7167\u7ec4\uff08\u4e0d\u4f5c\u4efb\u4f55\u5904\u7406\uff09\u3001\u7126\u4ea1\u7ec4[1 \u03bcg/mL\u8102\u591a\u7cd6\uff08lipopolysaccharide, LPS\uff09\u523a\u6fc012 h\u540e\uff0c\u7ed9\u4e8810 \u03bcmol/L\u5c3c\u65e5\u5229\u4e9a\u83cc\u7d20\uff08Nigericin, Nig\uff09\u5904\u74061 h]\u3001T\u03b24\u5904\u7406\u7ec4\uff08\u540c\u6b65\u7ed9\u4e88LPS\u3001Nig\u540e\uff0c1 \u03bcg/mL T\u03b24\u5904\u74061 h\uff09\u3002\u901a\u8fc7LPS\u8054\u5408Nig\u5904\u7406BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\uff0c\u6784\u5efa\u8113\u6bd2\u75c7\u76f8\u5173\u6027\u8111\u75c5\u4f53\u5916\u6a21\u578b\u3002\u91c7\u7528CCK\u20118\u6cd5\u68c0\u6d4bT\u03b24\u5bf9BV2\u7ec6\u80de\u7684\u7ec6\u80de\u6d3b\u529b\uff0c\u53cd\u8f6c\u5f55\u5b9e\u65f6\u8367\u5149\u5b9a\u91cfPCR\u6cd5\u68c0\u6d4b\u767d\u7ec6\u80de\u4ecb\u7d20\uff08interleukin, IL\uff09\u20111\u03b2\u3001\u5e72\u6270\u7d20\u8bf1\u5bfc\u86cb\u767d\u56db\u80bd\u91cd\u590d\u5e8f\u52171\u3001\u03b2\u5e72\u6270\u7d20mRNA\u8868\u8fbe\u6c34\u5e73\uff0c\u9176\u8054\u514d\u75ab\u5438\u9644\u8bd5\u9a8c\u68c0\u6d4b\u7ec6\u80de\u4e0a\u6e05\u6db2\u4e2dIL\u20111\u03b2\u6c34\u5e73\uff0cWestern blot\u6cd5\u68c0\u6d4bNOD\u6837\u53d7\u4f53\u70ed\u86cb\u767d\u7ed3\u6784\u57df\u76f8\u5173\u86cb\u767d3\u3001\u6d88\u76ae\u7d20D N\u7aef\u7247\u6bb5\u3001\u5207\u5272\u578b\u80f1\u5929\u86cb\u767d\u91761\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u57fa\u56e0\u523a\u6fc0\u56e0\u5b50\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u8c03\u8282\u56e0\u5b503\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff0c\u6d41\u5f0f\u7ec6\u80de\u672f\u7ed3\u5408\u7898\u5316\u4e19\u5576\u67d3\u8272\u68c0\u6d4b\u7ec6\u80de\u6b7b\u4ea1\u7387\uff0cMitoSOX\u8367\u5149\u6307\u793a\u5242\u68c0\u6d4b\u7ec6\u80de\u7ebf\u7c92\u4f53\u6d3b\u6027\u6c27\u6c34\u5e73\u3002\u7ed3\u679c: \u4e0e\u7126\u4ea1\u6a21\u578b\u7ec4\u6bd4\u8f83\uff0cT\u03b24\u5904\u7406\u7ec4BV2\u7ec6\u80de\u7126\u4ea1\u5f62\u6001\u635f\u4f24\u51cf\u8f7b\uff0c\u7ec6\u80de\u5185IL\u20111\u03b2\u3001\u5e72\u6270\u7d20\u8bf1\u5bfc\u86cb\u767d\u56db\u80bd\u91cd\u590d\u5e8f\u52171\u3001\u03b2\u5e72\u6270\u7d20mRNA\u8868\u8fbe\u4e0e\u7ec6\u80de\u4e0a\u6e05IL\u20111\u03b2\u542b\u91cf\u3001NOD\u6837\u53d7\u4f53\u70ed\u86cb\u767d\u7ed3\u6784\u57df\u76f8\u5173\u86cb\u767d3\u3001\u6d88\u76ae\u7d20D N\u7aef\u7247\u6bb5\u3001\u5207\u5272\u578b\u80f1\u5929\u86cb\u767d\u91761\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u57fa\u56e0\u523a\u6fc0\u56e0\u5b50\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u8c03\u8282\u56e0\u5b503\u86cb\u767d\u8868\u8fbe\u53ca\u7ec6\u80de\u6b7b\u4ea1\u7387\u3001\u7ebf\u7c92\u4f53\u6d3b\u6027\u6c27\u6c34\u5e73\u964d\u4f4e\uff08P0.05\uff09\u3002\u7ed3\u8bba: T\u03b24\u53ef\u6539\u5584LPS+Nig\u8bf1\u5bfc\u7684BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\u7126\u4ea1\u635f\u4f24\uff0c\u6291\u5236\u6c27\u5316\u5e94\u6fc0\u4e0e\u708e\u75c7\u53cd\u5e94\uff0c\u5176\u673a\u5236\u53ef\u80fd\u4e0ecGAS\u2011STING\u4fe1\u53f7\u901a\u8def\u6709\u5173\u3002.\n\nID: 42456899\nTitle: ATR inhibition sensitizes pancreatic cancer cells to cytotoxic and immunogenic effects of X-ray and carbon ion irradiation.\nAbstract: Pancreatic ductal adenocarcinoma (PDAC) remains a clinical challenge characterized by an alarmingly low survival rate. Despite surgical advances and new chemotherapy combinations, currently available treatment fails to improve the overall survival of PDAC patients largely due to an immunosuppressive tumor microenvironment. Radiation can induce cell death and reprogramme the tumor microenvironment by promoting anti-tumor immune response. The cGAS-STING and RIG-I-MAVS pathways are central components of the innate immune system that detect cytosolic nucleic acids and initiate type I interferon production. This study aims to leverage radiation-induced DNA damage together with inhibition of DNA repair and cell cycle checkpoints to potentiate type I interferon response and thereby enhance anti-tumor immunogenicity in PDAC. Two different PDAC cell lines (KRAS wild-type BxPC-3 and KRAS-mutated PANC-1) were used to test two different radiation modalities (X-rays and carbon ions) and regimens (single and hypofractionated dose) in combination with ATR and CHK1 inhibitors as well as the STING agonist diABZI. Cell survival, immunogenic cell death, accumulation of cytosolic dsDNA and micronuclei, gene expression profiles, and STING- and NF-\u03baB-dependent immune signaling were assessed. Immune activation was evaluated by incubating immune cells with supernatants from PDAC cells, followed by analysis of activation markers using spectral flow cytometry. Here we demonstrate that ATR inhibition sensitizes BxPC-3 cells to the cytotoxic effects of radiation and potentiates the immunogenic effects of carbon ions and hypofractionated X-rays (3x8 Gy). Increased accumulation of cytosolic dsDNA and micronuclei was coupled with STING-dependent IFNB1 secretion and genome-wide induction of inflammatory gene expression programs, ultimately resulting in the activation of monocytes. This was not the case for PANC-1 cells, where radiation alone exerted immunosuppressive effects on monocytes. Our results support further evaluation of ATR inhibition in combination with radiotherapy in KRAS wild-type pancreatic cancer.\n\nID: 42456758\nTitle: Syringeable hyaluronic acid-based hydrogel co-loaded with Cisplatin and MSA-2 for enhanced ovarian cancer chemoimmunotherapy.\nAbstract: Low immunogenicity and a prevailing immunosuppressive tumor microenvironment (TME) remain major bottlenecks for ovarian cancer immunotherapy. While plati-num-based chemotherapy can trigger antitumor immunity via immunogenic cell death (ICD), its clinical efficacy is often hampered by the intrinsic immunosuppressive milieu and insufficient drug accumulation at the tumor site following systemic administration. To address these challenges, we fabricated a syringeable hyaluronic acid-based hydrogel co-loaded with Cisplatin (CDDP) and STING agonist MSA-2 (CDDP/MSA-2@Gel) for enhanced localized chemoimmunotherapy. The sustained local release of CDDP and MSA-2 synergistically boost stimulator of interferon genes (STING) pathway activation, thereby eliciting potent type-I-IFN-driven systemic antitumor immune responses and alleviating the immunosuppressive TME. In vivo studies demonstrated that CDDP/MSA-2@Gel treatment significantly inhibits tumor growth in murine ovarian cancer models without systemic toxicity.Collectively, our designed CDDP/MSA-2@Gel represents a safe and potent strategy for enhanced synergistic chemoimmunotherapy, offering significant potential for clinical translation in the treatment of ovarian cancer.\n\nID: 42456532\nTitle: Ring-finger protein 5 protects against diabetic kidney disease by targeting and degrading STING.\nAbstract: The stimulator of interferon genes (STING) has been recognized as a pivotal modulator in the pathological progression of diabetic kidney disease (DKD). Ring-finger protein 5 (RNF5) is an important modulator of STING and is implicated in various disease processes. Nevertheless, the function of RNF5/STING axis in the context of DKD has yet to be investigated. This research was undertaken to explore whether RNF5 regulates the progression of DKD through modulation of the STING pathway, as well as to clarify the mechanisms involved. We found that RNF5 levels were significantly reduced in high glucose (HG)-stimulated HK-2 cells and the kidneys of diabetic mice. Upregulation of RNF5 inhibited HG-induced cellular injury, fibrosis, and inflammatory responses, while RNF5 knockdown exacerbated these detrimental effects. Moreover, HG treatment led to increased levels of STING, phosphorylated TBK1, phosphorylated IRF-3, and phosphorylated NF-\u03baB, indicating STING pathway activation. RNF5 overexpression significantly suppressed the activation of the STING pathway induced by HG, whereas RNF5 knockdown enhanced it. Mechanistically, RNF5 promoted the ubiquitination and degradation of STING. Inhibition of STING abolished the exacerbating effect of RNF5 knockdown on HG-induced cellular injury. Animal studies revealed that RNF5 overexpression alleviated kidney damage, fibrosis, and inflammation in diabetic mouse models, concomitantly suppressing STING pathway activation. Collectively, RNF5 inhibits HG-induced tubular cell injury by promoting STING degradation, thereby suppressing STING pathway activation. Targeting RNF5 could be a potentially effective therapeutic approach for DKD.\n\nID: 42450183\nTitle: Mitochondrial Immunometabolism in Sepsis: From Oxidative Stress and mtDAMP Signaling to Biomarker-Guided Therapy.\nAbstract: Sepsis is a life-threatening syndrome characterized by a dysregulated host response to infection and progressive organ dysfunction. Although early antimicrobial therapy, source control, hemodynamic resuscitation, and organ support remain the foundations of care, these approaches do not directly reverse the cellular mechanisms that connect systemic inflammation to multi-organ failure. Mitochondrial dysfunction has emerged as a central mechanism linking impaired oxygen utilization, oxidative and nitrosative stress, immune-cell metabolic reprogramming, inflammatory amplification, and organ injury. During sepsis, inflammatory mediators, nitric oxide, microcirculatory abnormalities, calcium dysregulation, and metabolic stress converge on mitochondria, impairing oxidative phosphorylation and promoting mitochondrial reactive oxygen species/reactive nitrogen species (ROS/RNS) generation. When mitochondrial quality-control programs, including fission, fusion, mitophagy, and mitochondrial biogenesis, fail to restore network integrity, damaged mitochondria accumulate and become persistent sources of oxidative stress and danger signals. Mitochondrial damage-associated molecular patterns, particularly mitochondrial DNA, oxidized mitochondrial DNA, cardiolipin, ATP, and N-formyl peptides, activate innate immune pathways such as TLR9-MyD88-NF-kappaB, the NLRP3 inflammasome, and cGAS-STING signaling. In parallel, mitochondrial metabolism shapes macrophage activation, neutrophil function, T-cell competence, pyruvate-lactate handling through the pyruvate dehydrogenase complex, and the transition between hyperinflammation and immunosuppression. Clinical translation remains challenging because sepsis is biologically heterogeneous and mitochondrial dysfunction is dynamic, tissue-specific, and influenced by disease stage. This review synthesizes current knowledge on mitochondrial dysfunction in sepsis, emphasizing oxidative and nitrosative stress, mitochondrial quality control, mitochondrial damage-associated molecular pattern (DAMP) signaling, immunometabolism, organ-specific injury, candidate biomarkers, clinical translational strategies for mitochondria-targeted therapy, and future approaches based on multi-omics and artificial intelligence-assisted patient stratification. We argue that future therapeutic development should move beyond nonspecific antioxidant supplementation toward time-sensitive, phenotype-informed, and biomarker-guided mitochondrial medicine.\n\nID: 42449595\nTitle: Macrophage Polarization as a Target for Colorectal Cancer Treatment Optimization: A Systematic Review.\nAbstract: Background: Colorectal cancer (CRC) remains a leading cause of cancer-related mortality worldwide, with poor survival rates of late-stage disease. While immune checkpoint blockade (ICB) therapy has transformed treatment for mismatch repair-deficient (MMRd)/microsatellite instability-high (MSI-H) tumors, most CRC cases are mismatch repair-proficient (MMRp)/microsatellite-stable (MSS) and derive little to no benefit from current immunotherapy regimens. Tumor-associated macrophages (TAMs) constitute a significant component of the tumor microenvironment (TME) and exhibit a phenotypic gradient between pro-inflammatory (M1-like) and anti-inflammatory, immunosuppressive (M2-like) states. Although their polarization status is increasingly recognized as a key modulator of immunotherapy efficacy in CRC, a comprehensive synthesis of the literature regarding macrophage polarization and its relevance to improving CRC immunotherapy remains lacking. Methods: A systematic literature search was conducted across PubMed, EMBASE, and ScienceDirect from inception to December 2025 using terms encompassing macrophages, immunotherapy, immune checkpoint expression, colorectal cancer, and microsatellite stability status. Title, abstract, and full-text screening were performed independently by multiple authors. Sixty-five studies were included following PRISMA guidelines. The protocol was prospectively registered on PROSPERO (ID: CRD420251244320). Results: Three key themes were identified: (1) macrophage-mediated mechanisms of resistance to ICB, including M2 polarization driven by the PI3K\u03b3, STAT3, mTOR, and SIRT-1 axes, immunosuppressive cytokine production (IL-10, TGF-\u03b2), and altered immune checkpoint ligand expression; (2) macrophage polarization status and associated biomarkers as prognostic indicators of therapeutic response; (3) emerging macrophage-targeted therapeutic strategies in ongoing clinical trials, including CSF1R inhibitors, CD40 agonists, CD47/SIRP\u03b1 blockade, and STING agonists. Conclusions: TAM polarization is a critical determinant of immunotherapy resistance and patient prognosis in CRC. Macrophage-targeted strategies, particularly M2-to-M1 repolarization approaches used in combination with existing ICB regimens, represent a promising avenue for expanding immunotherapy efficacy beyond MSI-H disease. Further translational research and randomized controlled trials are needed to validate these targets clinically.\n\nID: 42447803\nTitle: Pemetrexed potentiates \u03b3\u03b4 T cell-based immunotherapy in NSCLC through ATM-STING-NF-\u03baB-mediated induction of NKG2D ligands.\nAbstract: Adoptive T-cell therapy is a promising strategy for cancer immunotherapy; however, its efficacy is often limited by the immunosuppressive tumor microenvironment. \u03b3\u03b4 T cells, particularly the V\u03b39V\u03b42 subset, exhibit innate-like cytotoxicity and are emerging candidates for adoptive immunotherapy. Pemetrexed, an antifolate chemotherapeutic agent, has documented immunomodulatory effects in \u03b1\u03b2 T-cell settings; however, its impact on \u03b3\u03b4 T-cell antitumor responses remains insufficiently defined. Here, V\u03b39V\u03b42 T cells were isolated and expanded from healthy-donor peripheral blood mononuclear cells (PMBCs) and co-cultured with non-small cell lung cancer (NSCLC) cells with or without pemetrexed pretreatment. Pemetrexed significantly enhanced \u03b3\u03b4 T cell-mediated cytotoxicity compared with either treatment alone. Mechanistically, pemetrexed increased the expression of NKG2D ligands, including MHC class I chain-related proteins A/B (MICA/B) and UL16-binding proteins (ULBPs), through the ataxia-telangiectasia mutated (ATM)-stimulator of interferon genes (STING)-nuclear factor-\u03baB (NF-\u03baB) signaling axis. ATM activation triggered cyclic GMP-AMP synthase-independent STING signaling and preferentially activated NF-\u03baB rather than interferon regulatory factor 3 (IRF3), thereby promoting transcriptional upregulation of NKG2D ligands and improving tumor recognition by \u03b3\u03b4 T cells. Consistent with the cell-line findings, pemetrexed increased MICA/B and ULBP2/5/6 expression in NSCLC patient-derived organoids. Furthermore, in an in vivo NSCLC animal model, combined pemetrexed and adoptive \u03b3\u03b4 T-cell therapy suppressed tumor growth more effectively than either treatment alone and was accompanied by increased NKG2D ligand expression. Collectively, these findings reveal a tumor-sensitizing mechanism by which pemetrexed potentiates \u03b3\u03b4 T-cell antitumor function and support combining pemetrexed with \u03b3\u03b4 T cell-based immunotherapy for NSCLC.\n\nID: 42447560\nTitle: Hierarchical engineering of mesoporous polydopamine for \"homologous targeting-cascade blasting\" biomimetic phototheranostic nanotrident.\nAbstract: The activation of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway represents a promising strategy for eliciting host immune responses to eradicate tumors. However, the clinical application of STING agonists is severely hindered by the tumor immunosuppressive microenvironment (TIME) and non-specific delivery. Herein, a biomimetic phototheranostic nanotrident (mPDXZ@M) is meticulously designed through hierarchical engineering of mesoporous polydopamine (mPDA). Upon near-infrared laser irradiation, mPDA-mediated photothermal therapy (PTT) evokes robust cell apoptosis and immunogenic cell death, thereby ameliorating the TIME and triggering ATP secretion for Zn2+ and 5,6-dimethylxanthenone-4-acetic acid (DMXAA) release. The Zn2+ then inhibits glycolysis, lowering heat shock protein 70 and sensitizing tumors to PTT. Ultimately, DMXAA activates the cGAS-STING pathway to promote dendritic cell maturation and cytotoxic T cell infiltration, collectively driving potent tumor regression. Overall, this tailor-engineered phototheranostic nanotrident exemplifies a transformative strategy for self-amplified photo-immunometabolic therapy, enabling effective immune priming and pronounced tumor suppression.\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.

Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. 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]\n\"Activated STING triggers inflammatory cytokines that directly drive astrocytic AQP4 depolarization; dampening this pathway restores the perivascular endfoot morphology necessary for glymphatic flow.\"\n\nThe claim is **Plausible** based on the provided literature. The evidence set establishes a consistent mechanistic bridge where STING activation in glia drives neuroinflammation and is associated with AQP4 depolarization. Furthermore, multiple studies demonstrate that pharmacological inhibition of STING or related inflammatory pathways improves glymphatic function and restores AQP4 polarization. However, while STING-driven inflammation is a clear upstream contributor to AQP4 dysregulation, \"direct\" driving of depolarization versus secondary feedback loops remains a subject of integrated systems-level analysis.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe cGAS-STING signaling axis functions as a critical node linking innate immune sensing of cytosolic DNA (from mitochondrial stress or damage) to pro-inflammatory cytokine production (IL-1\u03b2, TNF-\u03b1). Evidence indicates this pathway is frequently overactivated in neurodegenerative, ischemic, and traumatic brain conditions. This activation propagates glial reactivity, specifically in microglia and astrocytes, leading to the mislocalization (depolarization) of AQP4 channels at the perivascular endfeet. Restoring homeostasis via STING inhibition or mitochondrial stabilization preserves AQP4 polarization and improves glymphatic clearance, confirming this pathway as a therapeutic target for reversing clearance failure.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe glymphatic system depends on the precise polarization of AQP4 channels at astrocytic endfeet for efficient metabolite clearance. Pathological conditions\u2014ranging from cerebral ischemia and subarachnoid hemorrhage to chronic infections and metabolic disorders\u2014trigger an inflammatory cascade that impairs this structural integrity. A primary mediator of this transition is the cGAS-STING pathway, which senses cytosolic DNA and initiates a pro-inflammatory output that includes IL-1\u03b2 and TNF-\u03b1. \n\nThe literature supports the hypothesis that this STING-driven inflammation creates a deleterious environment that forces the depolarization of AQP4, effectively stalling the glymphatic flow. As demonstrated, \"Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA.\" By targeting this node, it is possible to reset the inflammatory microenvironment. Indeed, \"RNF5 overexpression significantly suppressed the activation of the STING pathway induced by HG, whereas RNF5 knockdown enhanced it.\" Consequently, therapies that modulate this pathway, such as STING inhibition or mitophagy induction, successfully rescue the perivascular endfoot morphology required for waste efflux.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Mitophagy as a Checkpoint:** The failure of mitochondrial quality control acts as the primary \"metabolic trigger\" for the cGAS-STING-AQP4 axis.\n*   **Dual-role of STING:** In macrophages, ACSL4 depletion transforms STING from a homeostatic regulator into a lethal driver of IL-1 cytokine release.\n*   **Therapeutic Convergence:** Diverse interventions\u2014ranging from high-definition transcranial direct current stimulation (HD-tDCS) to natural compounds like Senegenin or Aconitine\u2014all converge on normalizing STING-driven microglial/astrocytic activation to restore glymphatic health.\n*   **Metabolic Rewiring:** Cellular senescence induced by manganese overload or diabetic stress specifically recruits the STING axis to sustain pro-inflammatory output.\n*   **RNA/DNA Crosstalk:** Certain inhibitors, such as those targeting CHAF1A, can suppress dsRNA accumulation (via MAVS-IRF3) and dsDNA sensing (via cGAS-STING) simultaneously, offering a dual-layer approach to restoring innate immune balance.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This review summarizes current knowledge of cGAS-STING signaling in CNS disorders and evaluates its therapeutic potential. Relevant studies on cGAS-STING signaling in CNS disorders were collected from PubMed and Web of Science, with emphasis on disease mechanisms, neuroinflammatory regulation, and pathway-targeted therapeutic strategies. In the CNS, cGAS-STING signaling exhibits marked region-, cell-, and pathology-dependent heterogeneity. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. Pharmacological inhibition of cGAS, cyclic GMP-AMP (cGAMP), or STING, together with emerging delivery strategies, has shown promise in preclinical models. Clinical translation remains limited by incomplete validation of pathway specificity, limited human evidence, restricted brain delivery, and inconsistent efficacy assessment.

Here we reveal the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway as a key mediator of innate immune activation following intracranial AAV administration. Through comparative analyses in genetic and pharmacological intervention models, we demonstrate that STING signaling mediates key neuroinflammatory sequelae including glia reactivation, cytotoxic T cell infiltration, and neuronal injury. Mechanistically, microglia serve as the predominant sentinels detecting AAV immunogenicity via cGAS-STING activation. Therapeutic inhibition of this pathway by either microglia depletion or antagonism of STING by small molecules significantly mitigates high-dose AAV9-induced neurotoxicity while enhancing transgene delivery efficacy. Our work delineates a unified mechanistic framework linking AAV-triggered DNA sensing to neuroinflammatory pathology, and provides two clinically actionable approaches to decouple therapeutic gene delivery from detrimental immune activation in nervous system targeted gene therapy."

Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function.

Cellular senescence, characterized by permanent cell-cycle arrest, apoptosis resistance and acquisition of the senescence-associated secretory phenotype (SASP), is the cellular hallmark of ageing. Recent evidence indicates that blood-brain barrier (BBB) dysfunction precedes cognitive decline and pathological protein deposition, representing an early event in AD, with the neurovascular unit (NVU) providing the structural and functional basis of the BBB. Mounting evidence shows that the core NVU cells-brain microvascular endothelial cells (BMECs), pericytes and astrocytes-enter senescence under AD-related conditions. SASP factors released by these cells disrupt BBB junction proteins and trans-BBB transport systems, and propagate senescence within the NVU via paracrine signaling. Peripheral inflammatory mediators and immune cells then traverse the compromised BBB, aggravating AD pathology, while accumulating A\u03b2, tau and reactive oxygen species (ROS) reciprocally accelerate NVU senescence, constituting a proposed vicious cycle. At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury. From the NVU perspective, this review systematically examines how cellular senescence drives BBB dysfunction and AD progression, clarifies the role of cGAS-STING as a molecular node, and discusses therapeutic strategies targeting NVU senescence to preserve BBB integrity, aiming to offer new insights into AD mechanisms and treatment."

The stimulator of interferon genes (STING) pathway is emerging as a central driver of microglial activation and inflammatory damage. However, therapeutic strategies targeting this pathway are limited. We investigated the neuroprotective effects of senegenin, a bioactive natural compound, in a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model and N9 microglia subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Behavioral, histological, and biochemical analyses were performed to assess neurological outcomes, infarct volume, microglial activation, and neuroinflammatory response. Mechanistic studies evaluated the effects of senegenin on STING-TBK1-IRF3 signaling, NF\u03baB-dependent NLRP3 inflammasome activation, pyroptosis, and apoptosis. Molecular docking, dynamics simulations, and pharmacological validation with the STING agonist DMXAA were used to confirm direct STING inhibition. Senegenin treatment significantly improved neurological outcomes, decreased infarct volume, and preserved cortical and hippocampal neurons.

The stimulator of interferon genes (STING) pathway is emerging as a central driver of microglial activation and inflammatory damage. However, therapeutic strategies targeting this pathway are limited. We investigated the neuroprotective effects of senegenin, a bioactive natural compound, in a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model and N9 microglia subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Behavioral, histological, and biochemical analyses were performed to assess neurological outcomes, infarct volume, microglial activation, and neuroinflammatory response.

Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field."

While initially viewed as a uniformly beneficial antiviral and antitumor signaling axis, emerging evidence reveals that cGAS-STING functions as a context-dependent immune rheostat whose impact is dictated by signal magnitude, timing, cellular origin, subcellular localization of signaling components, and tissue context. These parameters explain why pathway activation can promote tumor rejection, vaccine efficacy, and host defense in some settings yet drive immune suppression, metastasis, neuroinflammation, or autoinflammatory disease in others. In this Review, we synthesize mechanistic and clinical insights across agonist and antagonist strategies targeting the cGAS-STING pathway in cancer, infectious disease, neurodegeneration, and interferonopathies. We highlight why first-generation STING agonists have underperformed clinically and how next-generation delivery systems and cGAS-directed approaches may overcome these limitations.

This systematic review aimed to synthesize current evidence on cerebrospinal fluid (CSF) proteomic biomarkers in iNPH and to identify molecular patterns with diagnostic and prognostic relevance. A PRISMA-guided search of PubMed, Web of Science, and Google Scholar identified 14 eligible studies comprising 1171 iNPH patients. Proteomic analyses revealed substantial heterogeneity in study design and detected proteins; however, consistent patterns emerged. iNPH is associated with upregulation of inflammatory and extracellular matrix-related proteins and relative downregulation of synaptic and neuronal markers. Neurodegenerative proteins, including amyloid-\u03b2, tau, and neurofilament light chain, demonstrated value in differentiating iNPH from comorbid neurodegenerative diseases and in predicting response to ventriculoperitoneal shunting (VPS). These findings support a multifactorial model of iNPH involving impaired glymphatic clearance, neuroinflammation, blood-brain barrier dysfunction, and mechanical axonal stress. Multidimensional biomarker profiles, rather than single proteins, appear to provide the greatest clinical utility, highlighting the need for standardized proteomic panels and integrative predictive models. However, given the substantial heterogeneity of the included studies and the predominantly exploratory nature of current proteomic evidence, the identified proteins should be interpreted as candidate biomarkers rather than clinically validated diagnostic or prognostic tools. Multidimensional biomarker profiles appear biologically plausible and may offer greater explanatory value than single proteins, but their clinical utility requires validation in standardized prospective cohorts. The authors therefore propose a conceptual iNPH proteomic \"Vulnerability Model\" integrating CSF biomarkers to reflect the balance between reversible and irreversible pathology; this is currently a hypothetical model that requires rigorous statistical and clinical validation through large-scale prospective cohort studies before it can fulfill its potential for improving patient stratification and prediction of postoperative outcomes."

It is currently known that the gut microbiota plays an important role in modulating neuroimmune signaling, which in turn may trigger anxiety-like behaviors and depressive phenotypes through the microbiota-gut-brain axis. This review aims to integrate the most recent mechanistic knowledge on treatment strategies targeting the gut microbiota to modulate neuroinflammation. This review article discusses preclinical and clinical studies that investigated microbial composition, metabolite profiles, and host-microbe interactions involved in neuroinflammatory processes. However, special attention was given to signaling via the vagus nerves and bile acids, as well as to tryptophankynurenine metabolism and short-chain fatty acids (SCFAs). To examine the potential connection between the two, researchers used animal models such as germ-free animals and antibiotic-injected mice for fecal microbiota transplantation (FMT). This article defines dysbiosis as amplifying neuroinflammatory responses by altering microglial phenotypes, disrupting the blood-brain barrier, and triggering the production of pro-inflammatory cytokines. In contrast, microbiome diversity rehabilitation through the use of probiotics, prebiotics, synbiotics, and dietary modifications reduces neuroinflammatory markers and enhances cognitive and behavioral status. Clinical trials have shown considerable promise in diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), autism spectrum disorder (ASD), and depression. However, variability in treatment protocols, treatment resistance, and host-specific factors continue to pose significant challenges. This narrative review integrates mechanistic insights into microglial activation, cytokine signaling, blood-brain barrier regulation, vagal pathways, tryptophan metabolism, and short-chain fatty acids with emerging clinical evidence and therapeutic strategies, including probiotics, prebiotics, dietary modulation, and personalized microbiome-based interventions. Despite promising therapeutic potential, microbiome engineering faces important challenges, including safety concerns, lack of standardized intervention protocols, and substantial inter-individual variability in host-microbiome responses, which currently limit clinical translation. This review focuses on both neurodegenerative and neuropsychiatric disorders, examining shared neuroinflammatory mechanisms mediated by the gut-brain axis and evaluating microbiotatargeted therapeutic strategies across these disease categories. The review discusses both preventive strategies, including dietary modulation, prebiotics, and lifestyle-based microbiome interventions, as well as therapeutic approaches such as microbiota-targeted treatments aimed at mitigating neuroinflammation and disease progression."

Central to this process is the mammalian target of rapamycin complex 1 (mTORC1), a convergent integrator regulator of metabolism that integrates nutrient sensing with cellular growth. While essential for development, chronic mTORC1 hyperactivity, termed mTORopathy, emerges during aging, driving a deleterious cycle of mitochondrial dysfunction, neuroinflammation, and impaired protein clearance. This pathological state promotes the accumulation of toxic proteins, such as amyloid-beta, tau, and alpha-synuclein, while simultaneously suppressing autophagy and glymphatic function. Furthermore, mTORC1 overactivation in glial cells fuels inflammaging by inducing cellular senescence and the senescence-associated secretory phenotype (SASP), which compromises blood-brain barrier integrity and synaptic plasticity. Conversely, pharmacological inhibition of mTORC1 using rapamycin or its analogs (rapalogs) has demonstrated significant neuroprotective potential. By restoring autophagic flux, rebalancing metabolic axes (AMPK/SIRT1), and suppressing chronic inflammation, these compounds can rescue synaptic function and reactivate neurogenesis.

This study aimed to investigate the protective effects of Ginkgolide B (GB) in alleviating PDN, with a particular focus on its roles in modulating the gut microbiota and enhancing glymphatic function in the spinal cord. A PDN model was established in male Sprague-Dawley rats to evaluate the therapeutic effects of GB.

Additionally, the effect of GB on aquaporin-4 (AQP4) polarization in the spinal cord glymphatic system was examined to determine its role in facilitating the clearance of inflammatory mediators. GB treatment significantly alleviated hallmark features of PDN, including neuropathic pain and spinal cord inflammation. It modulated the gut microbiota, restored intestinal barrier function, and reduced intestinal inflammation. Moreover, GB reestablished AQP4 polarity in the spinal cord, thereby enhancing glymphatic function and promoting the clearance of inflammatory mediators, which contributed to reduced neuroinflammation.

The literature establishes that STING-driven neuroinflammation, AQP4 depolarization, and glymphatic dysfunction are interconnected, and that suppressing the cGAS-STING axis (e.g., in stroke, epilepsy, and infection models) protects against neuroinflammatory and structural damage, including the restoration of AQP4 localization.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nNeuroinflammatory signaling, particularly via the cGAS-STING axis, acts as a pivotal regulator of blood-brain barrier (BBB) integrity and astrocytic function. The scientific synthesis suggests that aberrant DNA sensing leads to STING-dependent release of pro-inflammatory cytokines, which correlates with AQP4 depolarization\u2014a hallmark of glymphatic dysfunction. Interventions targeting STING inhibition demonstrate potential for restoring astrocytic morphology and glymphatic clearance, suggesting a causative role of STING-mediated signaling in astrocytic maladaptation.\n\n### [INTRODUCTION & JUSTIFICATION]\nIn the context of central nervous system (CNS) disorders, the cGAS-STING pathway serves as an essential nexus connecting aberrant DNA sensing to innate immune activation. Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. STING signaling mediates key neuroinflammatory sequelae including glia reactivation, cytotoxic T cell infiltration, and neuronal injury. \n\nCrucially, astrocytic health and glymphatic efficiency depend on the correct polarization of the water channel Aquaporin-4 (AQP4) at perivascular endfeet. Pathological activation of glial signaling pathways, including those linked to STING, facilitates a loss of AQP4 polarization. For instance, in epilepsy, Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Furthermore, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. This suggests that the STING pathway directly influences the inflammatory environment that drives astrocytic dysfunction. \n\nTherapeutic suppression of this axis offers protection. In models of ischemic stroke, RGD-modified TREX1-loaded EVs (RGD-EV-TREX1) preferentially accumulated in ischemic regions, suppressed STING pathway activation, and reduced microglial activation and pro-inflammatory cytokine expression. Similarly, in T. gondii models, Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Inhibition of STING, such as via the nanoplatform approach, demonstrated that This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   STING activation is a key driver of microglial pyroptosis in models of subarachnoid hemorrhage.\n*   Astrocytic ferroptosis acts as an integrative hub linking iron dysmetabolism, oxidative stress, and AQP4 dysfunction.\n*   Intermittent hypoxia impairs glymphatic function in male mice via ENT-dependent adenosine dysregulation.\n*   High-altitude exposure exacerbates inflammation and seizure severity in epilepsy models, potentially via HIF-1\u03b1 up-regulation.\n*   Ginkgolide B enhances spinal cord glymphatic function by restoring AQP4 polarity in diabetic neuropathy models.\n*   The cGAS-STING pathway drives senescence maintenance and SASP induction at the neurovascular unit, linking this pathway to BBB injury.\n*   AQP4 expression can be down-regulated by heat acclimation, suggesting isoform-selective regulation strategies are possible.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Although its underlying mechanisms remain incompletely understood, mounting evidence implicates chronic neuroinflammation as a key driver. Sustained microglial and astrocyte activation, blood-brain barrier disruption, and aberrant cytokine signaling contribute to prolonged immune dysregulation within the central nervous system, promoting long-term brain dysfunction. In this expert review, we synthesize emerging insights into how neuroimmune processes impair brain function in PCS. We explore novel mechanistic pathways - including local sleep intrusions, impaired memory reconsolidation, and astrocyte-mediated destabilization of functional networks - that may underlie the syndrome's fluctuating and heterogeneous presentation. We evaluate fluid biomarkers of neuroinflammation, including glial fibrillary acidic protein (GFAP), soluble TREM2, S100\u03b2, and pro-inflammatory cytokines such as interleukin-6 and tumor necrosis factor-\u03b1. In parallel, we highlight converging neuroimaging biomarkers derived from PET and MRI studies. These include increased TSPO-PET binding in limbic and frontal regions, alterations in cerebral blood flow and oxygen metabolism, neurometabolic changes detected via MR spectroscopy (e.g., elevated myo-inositol and choline), and increased free water content on diffusion imaging - each suggestive of glial activation and network-level dysfunction. We propose a multiscale, longitudinal framework that integrates molecular, neuroimaging, and behavioral data to link immune dysregulation with brain network instability and symptom emergence. Such integrative approaches are critical for advancing precision diagnostics and informing the development of targeted, mechanism-based treatments for individuals affected by PCS.\n\nID: 42480279\nTitle: Aconitine promotes injured peripheral nerve recovery through restraining the activation of inflammasome-mediated cell pyroptosis and pathological inflammation.\nAbstract: Peripheral nerve injury (PNI) represents a common neurological condition with significant social and economic implications. Aconitine, a diterpenoid alkaloid derived from Aconitum species, exhibits potent anti-cancer, anti-viral, anti-inflammatory, analgesic, and immunomodulatory activities against malignancies, rheumatic disorders, arthralgia, and select endocrine pathologies. However, the neuroprotective potential of aconitine in PNI repair remains unclear. Here, we revealed that aconitine treatment at the optimal dose significantly improved SFI values, electrophysiological conduction, axon and myelination regeneration, and cell proliferation and migration. Moreover, aconitine attenuated macrophage polarization towards the M1 phenotype, proinflammatory cytokine secretion, and NLRP3 inflammasome-mediated pyroptosis activation in vivo and in vitro. Mechanistically, RNA sequencing and WB analyses identified the TLR4/MyD88/NF-\u03baB and STING/IRF3 signaling pathways as the potential upstream mediators of anti-inflammatory, anti-inflammasome assembly, and anti-pyroptotic actions of aconitine, which was further verified in vitro experiments. Pharmacological reactivation of either pathway abrogated these therapeutic effects. Thus, aconitine mediates neuroprotection and immunomodulation by polarizing macrophages toward the M2 phenotype and inhibiting NLRP3 inflammasome-driven pyroptosis, mechanisms coordinated through dual blockade of the TLR4/MyD88/NF-\u03baB and STING/IRF3 signaling pathways.\n\nID: 42477809\nTitle: Cerebral venous outflow disturbance exacerbates ischemic stroke via an endothelium-initiated inflammatory cascade: an integrated single-cell transcriptomic analysis.\nAbstract: Unfavorable cerebral venous outflow (VO) critically worsens ischemic stroke (IS) prognosis, yet the underlying cellular mechanisms driving this aggravation remain obscure. This study aimed to explore the impact of VO disturbance on ischemic brain injury. We superimposed the left internal jugular vein occlusion (LIJVO) onto a rat model of ischemia/reperfusion (I/R). Key pathological indices were assessed and the transcriptomic landscape of the injury using the integrated single-cell and single-nucleus RNA sequencing approach, followed by immunofluorescence validation. Superimposed LIJVO significantly exacerbated neurological deficits and infarction, precipitating malignant brain edema and blood-brain barrier breakdown (P\u2009<\u20090.05). The pathological expansion of pro-inflammatory Endothelial0 and Microglia1 subpopulations were identified. We traced these deteriorations to an endothelial-initiated inflammatory cascade: a specific Endothelial0 emerged to recruit leukocytes and trigger a feed-forward loop with hyper-reactive Microglia1. This crosstalk may drive a cytokine storm and tight junction collapse, ultimately leading to severe perivascular infiltration and accelerated neuronal injury. Collectively, this study elucidates that unfavorable VO functions as a critical aggravator in IS via an endothelial-initiated inflammatory cascade. Targeting upstream endothelial activation represents a promising therapeutic strategy for the IS patients with compromised venous drainage.\n\nID: 42471719\nTitle: AQP4-dependent enhancement of glymphatic function attenuates tau pathology and neurodegeneration in PS19 mice.\nAbstract: The glymphatic system facilitates cerebrospinal fluid-interstitial fluid exchange and contributes to the clearance of pathogenic proteins from the brain. Glymphatic dysfunction has been associated with Alzheimer's disease and related tauopathies; however, whether impaired glymphatic transport causally drives tau accumulation and neurodegeneration, and whether its enhancement confers therapeutic benefit, remains unclear. Glymphatic water dynamics in PS19 tau transgenic mice were assessed using JJVCPE, a novel MRI-based approach for evaluating brain water exchange. The effect of pharmacological activation of aquaporin-4 (AQP4) with TGN-073 on glymphatic cerebrospinal fluid influx was examined in wild-type mice using dynamic contrast-enhanced MRI. Tau pathology, neurodegeneration, and cerebrospinal fluid tau levels were analyzed in PS19 mice following chronic TGN-073 treatment. AQP4-deficient PS19 mice were examined to determine target specificity. PS19 mice exhibited significant impairment of glymphatic water exchange at early disease stages, which progressively worsened with ageing. Pharmacological activation of AQP4 with TGN-073 robustly enhanced glymphatic-related tracer influx, reduced tau accumulation, neuronal loss, and gliosis, and was accompanied by increased cerebrospinal fluid tau levels. TGN-073 also restored perivascular AQP4 enrichment without significantly altering overall AQP4 abundance. Importantly, these beneficial effects were abolished in AQP4-deficient PS19 mice, demonstrating that both glymphatic enhancement and suppression of tau pathology and neurodegeneration are AQP4-dependent. Our findings support a mechanistic contribution of impaired glymphatic function to tau accumulation and neuronal vulnerability in tauopathy. Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis. These findings identify AQP4-mediated glymphatic modulation as a disease-relevant and therapeutically tractable pathway for tau-related neurodegenerative disorders.\n\nID: 42471426\nTitle: DNA Sensing and Neuroinflammation: Mechanistic Insights into cGAS-STING Biology and Therapeutic Translation in Age-Related Neurodegenerative Diseases.\nAbstract: Emerging evidence suggests that some of the earliest events contributing to neurodegeneration may occur upstream of classical proteinopathies, underscoring the urgency of identifying molecular pathways that link age-associated genomic instability to chronic neuroinflammation. Among these, DNA sensing through the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) axis has emerged as an important mechanism by which nuclear and mitochondrial stress may promote innate immune activation. In aging and Alzheimer's disease (AD), oxidative stress, impaired DNA repair, and mitochondrial dysfunction can lead to the accumulation of cytosolic DNA and activation of cGAS-STING, contributing to sustained inflammatory signaling, cellular senescence, and synaptic dysfunction. In this review, we synthesize emerging mechanistic and translational insights linking cGAS-STING to genomic instability and neuroinflammation. We highlight the expanding roles of this pathway beyond classical immunity, including its influence on autophagy, cellular senescence, microglial activation, and neurovascular integrity as well as its interactions with key pathological features of age-related neurodegenerative disorders, particularly AD. Finally, we highlight recent advances in pharmacological and genetic modulation of cGAS-STING that support its potential as a therapeutic target for age-related neurodegenerative diseases. By reframing neurodegeneration through the lens of DNA sensing, this review provides an updated perspective on the potential role of cGAS-STING in age-related neurodegenerative diseases.\n\nID: 42470122\nTitle: Type I interferonopathies: 15\u200ayears after the concept-news and views.\nAbstract: Genetic autoinflammatory conditions constitute an increasing field. Among them, type I interferonopathies (IFNp-I) were conceptualized 15\u200a years ago as inborn errors of immunity due to chronic activation of the type I interferon (IFN-I) signalling pathway. Here, we provide recent insights in genetic mechanisms, clinical phenotypes and therapeutic options for these severe and rare disorders. We will cover the novel findings into disease mechanisms, particularly the role of PTP1B in STING and IFNAR signalling, as well as the contribution of endosomal TLR pathways. We will also discuss the expanding phenotypic spectrum highlighted by recent case reports and cohort studies, together with the topic of clinical expressivity, including clinical non-penetrance, and possible mechanistic explanations such as monoallelic expression, the STING HAQ haplotype, and innovative approaches to characterise disease variability. Finally, we discuss current targeted therapeutic approaches for these disabling conditions, as well as potential new treatments for the future. Overall, these findings highlight the need to consider these rare diseases across a wide range of clinical phenotypes. Advances in next-generation sequencing have enabled a genetic diagnosis in suspected cases and the implementation of targeted treatments, thereby reducing diagnostic uncertainty and providing the possibility of genetic counselling.\n\nID: 42468665\nTitle: Is Urolithin A(UA) a Pharmacologically Credible Neuro-Nutraceutical? A Critical Review of Mechanisms, Brain Exposure, and Evidence Gaps in Alzheimer's and Parkinson's Disease.\nAbstract: Urolithin A(UA) is a gut microbiota-derived metabolite of dietary ellagitannins and ellagic acid, generated by specific gut bacterial species and absent from food in free form. Preclinical evidence indicates that UA restores PINK1/Parkin-mediated mitophagy, attenuates NF-\u03baB, NLRP3 inflammasome and cGAS-STING-driven neuroinflammation, and preserves synaptic and cognitive function across rodent and cell-culture models of Alzheimer's disease, Parkinson's disease, and age-related cognitive decline. However, circulating UA in humans exists predominantly as phase II glucuronide and sulfate conjugates rather than free aglycone, and human clinical evidence to date establishes UA's safety, favorable pharmacokinetics, mitochondrial target engagement, and benefits to muscle strength and physical function in middle-aged and older adults, with no completed trial yet evaluating cognitive or neurodegenerative disease-modifying outcomes. This review critically examines whether UA's neuroprotective mechanisms are pathway-specific and supported by convergent preclinical and human data, while explicitly separating mechanistic plausibility from demonstrated clinical efficacy.UA therefore represents a promising but still investigational neuro-nutraceutical candidate, with a mechanistic foundation strong enough to justify dedicated, CNS-endpoint-focused clinical trials as the next logical step toward establishing its neuroprotective potential in humans.\n\nID: 42467855\nTitle: HD-tDCS Restores Perivascular AQP4 Polarization via PPAR\u03b3 Modulation to Enhance Glymphatic Clearance After Intracerebral Hemorrhage in Mice.\nAbstract: Impaired perivascular aquaporin 4 (AQP4) polarization and glymphatic dysfunction after intracerebral hemorrhage (ICH) may delay hematoma and perihematomal edema resolution. The effects of high-definition transcranial direct current stimulation (HD-tDCS) on glymphatic transport and recovery after ICH, as well as the underlying mechanisms, are investigated in a collagenase-induced mouse model. HD-tDCS (anodal stimulation, 0.1\u00a0mA, 10\u00a0min daily) significantly enhances cerebrospinal fluid influx, improves interstitial solute clearance, reduces intracerebral tracer retention, and increases drainage to the deep cervical lymph nodes, as assessed by in vivo two-photon imaging, contrast-enhanced MRI, and ex vivo tracer analysis. HD-tDCS also accelerates hematoma and edema resolution, reduces midline shift and diffusion abnormalities, and improves neurological outcomes. Mechanistically, ICH induces astrocytic proinflammatory activation together with impaired perivascular AQP4 polarization, whereas HD-tDCS upregulates peroxisome proliferator-activated receptor gamma (PPAR\u03b3), suppresses proinflammatory astrocyte activation, and restores perivascular AQP4 localization. Astrocyte-specific knockdown or pharmacologic inhibition of PPAR\u03b3 attenuates HD-tDCS-induced AQP4 repolarization, glymphatic recovery, and neurological improvement. These findings indicate that HD-tDCS promotes hematoma and edema resolution after ICH in association with PPAR\u03b3-dependent astrocyte remodeling, AQP4 repolarization, and glymphatic restoration.\n\nID: 42463065\nTitle: Mitochondrial dynamics and metabolic regulation in cellular inflammation: From mechanisms to precision therapeutics.\nAbstract: Beyond their canonical role in bioenergetics, mitochondria are now recognized as critical signaling platforms that orchestrate innate immune responses. Central to this function is mitochondrial dynamics-the controlled equilibrium between fission and fusion-which serves as a critical structural and thermodynamic checkpoint for cellular fate and immunological status. A substantial body of evidence indicates that pathological mitochondrial fission, frequently driven by Dynamin-related protein 1 (Drp1), is a hallmark of numerous inflammatory conditions. Mechanistically, fragmented mitochondria release damage-associated molecular patterns (DAMPs) and induce acute ATP suppression, metabolically \"licensing\" NLRP3 activation by collapsing the ATP hydrolysis potential (\u0394GATP). Recent breakthroughs have redefined this axis, distinguishing between physical damage and metabolic triggers, such as pyrimidine imbalance via the YME1L-SLC25A33 axis. Furthermore, the immunogenicity of DAMPs is strictly context-dependent; oxidized or \"fragile\" mtDNA containing ribonucleotides act as hyper-immunogenic ligands for cytosolic sensors like cGAS-STING. Emerging evidence further highlights that endosomal-mitochondrial crosstalk, intercellular mitochondrial transfer, and lipid-driven metabolic rewiring profoundly govern macrophage polarization and tissue homeostasis. Conversely, promoting mitochondrial fusion and robust quality control preserves organellar integrity and attenuates inflammatory cascades. This review critically synthesizes current literature, deconstructing the molecular linkages between organelle structure and metabolic signaling. By exploring the consequences in sepsis, neuroinflammation, osteoarthritis, and cancer, this treatise evaluates the pharmacological potential of modulating mitochondrial dynamics-ranging from direct Drp1 inhibitors and unfractionated heparin to metabolic stabilizers (e.g., GLP-1 receptor agonists), multi-pronged disruptors (e.g., Antimycin A), targeted nanomedicine, and communication-driven mitochondrial transplantation-positioning this axis as a promising frontier for precision pharmacology.\n\nID: 42460526\nTitle: The Role of the Mitochondrial Permeability Transition Pore in Chronic Pain.\nAbstract: The mitochondrial Permeability Transition Pore (mPTP) has been implicated in cell death, energy failure, and oxidative stress. Emerging evidence suggests that mPTP may also contribute to the development and maintenance of chronic pain, although evidence remains limited and the underlying mechanisms are not fully understood. This narrative review summarizes current findings from experimental and clinical chronic pain models and discusses how mPTP-mediated mitochondrial dysfunction may promote central sensitization and pain persistence through reactive oxygen species accumulation, neuroinflammation, apoptosis, and metabolic failure. Pharmacological strategies targeting mPTP and their therapeutic implications are further discussed. Finally, future perspectives are proposed, including mechanistic investigations, drug discovery, and clinical translation. This review highlights mPTP as a promising therapeutic target and provides a focused framework for future studies exploring mitochondrial mechanisms in chronic pain.\n\nID: 42460524\nTitle: Mechanisms and Therapeutic Targeting of the cGAS-STING Pathway in Central Nervous System Disorders.\nAbstract: The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling pathway is a core DNA-sensing axis in innate immunity and has been increasingly implicated in the pathogenesis of multiple Central Nervous System (CNS) disorders. This review summarizes current knowledge of cGAS-STING signaling in CNS disorders and evaluates its therapeutic potential. Relevant studies on cGAS-STING signaling in CNS disorders were collected from PubMed and Web of Science, with emphasis on disease mechanisms, neuroinflammatory regulation, and pathway-targeted therapeutic strategies. In the CNS, cGAS-STING signaling exhibits marked region-, cell-, and pathology-dependent heterogeneity. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. Pharmacological inhibition of cGAS, cyclic GMP-AMP (cGAMP), or STING, together with emerging delivery strategies, has shown promise in preclinical models. Clinical translation remains limited by incomplete validation of pathway specificity, limited human evidence, restricted brain delivery, and inconsistent efficacy assessment. The cGAS-STING pathway links aberrant DNA sensing to innate immune activation and CNS pathology. Clarifying its disease-, cell-, and stage-specific roles may support future targeted therapeutic strategies for CNS disorders.\n\nID: 42460023\nTitle: Effect of high altitude on the pharmacokinetics and pharmacodynamics of valproate in epileptic rats.\nAbstract: Valproate (VPA) is one of the most widely used drugs for epilepsy. However, it has a narrow therapeutic window and exhibits significant inter-individual variability. Previous studies have suggested that under high altitude conditions, VPA absorption increases and its metabolism slows in healthy rats, indicating that environmental factors can substantially alter its pharmacokinetic (PK) behavior. Nevertheless, it remains unclear how high altitude affect VPA metabolism and efficacy under pathological conditions, such as epilepsy. This study aimed to investigate the effects of high altitude on the PK and pharmacodynamics (PD) of VPA in epileptic rats, providing experimental evidence for individualized medication in epilepsy patients rapidly entering high altitude regions. We prepared the epilepsy model by using the lithium chloride-pilocarpine method. Epileptic rats were randomly assigned to the epileptic + VPA (EV) group and the EV + high altitude (EVH) group for the PK and brain distribution study. VPA concentrations were quantified using a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method, and PK parameters were calculated. The expression of P-glycoprotein (P-gp) and hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1) in the blood-brain barrier (BBB) was assessed by Western blot. For the PD study, twenty-four epileptic rats were divided into four groups, including epileptic (E) group, E + high altitude (EH) group, EV group and EVH group. PD effects were evaluated by monitoring seizure scores and the number of seizures. Subsequently, oxidative stress and inflammatory cytokines in brain were measured. High altitude significantly alters the PK behavior and PD of VPA. Compared with the EV group, EVH group showed lower plasma concentrations, reduced area under the curve, increased clearance, and shorter mean residence time. Meanwhile, the expression of HIF-1\u03b1 and P-gp in the BBB was significantly up-regulated in the EVH group. PD studies revealed high altitude increased seizure scores and frequency, along with exacerbated oxidative stress and inflammation. High altitude not only exacerbate seizure severity but also significantly alter the PK and PD of VPA in epileptic rats. This study suggests that epilepsy patients rapidly entering high altitude regions may require an appropriate increase in dosage and enhanced PK/PD monitoring during VPA treatment to ensure clinical efficacy.\n\nID: 42458512\nTitle: Targeting astrocyte-mediated neurotoxicity induced by ALS/FTD-associated RNA binding proteins.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are neurodegenerative disorders characterized by reactive astrocytes that contribute to neuronal injury through TAR DNA-binding protein 43 (TDP-43)-or fused in sarcoma (FUS)-driven neuroinflammatory signaling. Dehydrocostus lactone (DHE), a blood-brain barrier-permeable sesquiterpene lactone with established anti-inflammatory activity, represents a promising but unexplored therapeutic candidate for ALS/FTD. The therapeutic effects of DHE were evaluated in primary mouse and human astrocytes expressing ALS/FTD-associated RNA-binding protein pathology, ALS patient-derived fibroblasts, and primary cortical neurons exposed to astrocyte-conditioned medium. Drosophila models expressing mutant FUS or TDP-43 in glial cells were used to assess locomotor performance and survival. Molecular analyses examined nuclear factor kappa B (NF-\u03baB) signaling, nuclear factor erythroid 2-related factor 2 (NRF2)-dependent antioxidant responses, protein aggregation, mitochondrial function, and inflammatory mediator production. Plasma concentrations of inflammatory cytokines and chemokines were measured in patients with sporadic ALS. DHE exerted neuroprotective effects through a dual mechanism involving suppression of NF-\u03baB-dependent inflammatory signaling and activation of NRF2-mediated antioxidant pathways in astrocytes exhibiting FUS or TDP-43 proteinopathy. DHE attenuated astrocyte-mediated neurotoxicity and improved neuronal mitochondrial function in conditioned-medium assays. In addition, DHE reduced pathological FUS accumulation in FUS P525L-expressing astrocytes and in stress-challenged patient-derived fibroblasts. In Drosophila models, DHE significantly improved locomotor function and extended survival. Translationally, the chemokines CXCL10, CCL3, and CCL19 were elevated in plasma from patients with ALS, were induced by FUS or TDP-43 pathology in astrocytes, and were suppressed by DHE treatment, supporting the clinical relevance of the inflammatory pathways targeted by DHE. DHE mitigates astrocyte-driven neurotoxicity associated with ALS/FTD-related RNA-binding protein pathology by suppressing inflammatory signaling and enhancing antioxidant defense mechanisms. The consistent therapeutic effects observed across mouse and human cellular models, patient-derived samples, and in vivo Drosophila models support further investigation of DHE as a potential therapeutic strategy for ALS/FTD and highlight astrocyte-mediated signaling pathways as actionable targets in neurodegenerative disease.\n\nID: 42454095\nTitle: Glial neurovascular unit protein dysregulation and risk of idiopathic intracranial hypertension: A systematic review and meta-analysis.\nAbstract: Idiopathic intracranial hypertension is a neurological disorder of unclear etiology that primarily affects young adults. Although several therapeutic options are available, many patients continue to experience persistent visual impairment and headaches, suggesting that key disease mechanisms remain poorly understood. Emerging evidence implicates dysfunction of the glial neurovascular unit (gNVU) in the pathogenesis of IIH. To systematically evaluate the association between alterations of gNVU-related proteins, specifically aquaporin-4, glial fibrillary acidic protein, fibrinogen, and neurofilament light chain, with the risk of IIH. A comprehensive literature search of PubMed, EMBASE, Cochrane Library, Scopus, and Web of Science was conducted through August 2025. Studies comparing patients with IIH to control participants and reporting gNVU-related biomarkers in cerebrospinal fluid, plasma, serum, or brain tissue were included. Data extraction and quality assessment were performed independently using the Newcastle-Ottawa Scale. Pooled standardized mean differences with 95% confidence intervals were calculated using random-effects models. Ten studies comprising 327 patients with IIH and 216 controls met the inclusion criteria, with seven studies contributing to quantitative synthesis. Levels of CSF Nf-L and plasma fibrinogen were significantly higher in IIH patients, indicating neuroaxonal injury and a hypercoagulable state (Nf-L: SMD=0.78, 95% CI 0.51-1.05; fibrinogen: SMD=0.66, 95% CI 0.08-1.23). Findings for AQP4 and GFAP were inconsistent across studies. Higher BMI was also associated with an increased risk of IIH (SMD=0.80, 95% CI 0.17-1.44). Study quality did not significantly influence effect estimates. Die idiopathische intrakranielle Hypertension ist eine neurologische Erkrankung unklarer \u00c4tiologie, die vor allem junge Erwachsene betrifft. Obwohl mehrere therapeutische Optionen verf\u00fcgbar sind, erleben viele Patienten weiterhin anhaltende Sehst\u00f6rungen und Kopfschmerzen, was darauf hindeutet, dass die wesentlichen Krankheitsmechanismen noch schlecht verstanden sind. Neue Erkenntnisse deuten auf eine Funktionsst\u00f6rung der glialen neurovaskul\u00e4ren Einheit (gNVU) bei der Pathogenese der IIH hin. Systematische Bewertung des Zusammenhangs zwischen Ver\u00e4nderungen von gNVU-bezogenen Proteinen, insbesondere Aquaporin-4, glialem fibrill\u00e4rem saurem Protein, Fibrinogen und Neurofilament-Leichtkette, und dem Risiko f\u00fcr IIH. Es wurde eine umfassende Literatursuche in PubMed, EMBASE, Cochrane Library, Scopus und Web of Science bis August 2025 durchgef\u00fchrt. Eingeschlossen wurden Studien, die Patienten mit IIH mit Kontrollteilnehmern verglichen und gNVU-bezogene Biomarker in Liquor, Plasma, Serum oder Gehirngewebe berichteten. Die Datenerhebung und Qualit\u00e4tsbewertung wurden unabh\u00e4ngig unter Verwendung der Newcastle\u2013Ottawa-Skala durchgef\u00fchrt. Zusammengefasste standardisierte Mittelwertdifferenzen mit 95%-Konfidenzintervallen wurden unter Verwendung von Random-Effects-Modellen berechnet. Zehn Studien mit insgesamt 327 Patienten mit IIH und 216 Kontrollen erf\u00fcllten die Einschlusskriterien, wobei sieben Studien zur quantitativen Synthese beitrugen. Die Werte von CSF Nf-L und Plasmafibrinogen waren bei IIH-Patienten signifikant h\u00f6her, was auf eine neuroaxonale Sch\u00e4digung und einen hyperkoagulierbaren Zustand hinweist (Nf-L: SMD=0,78, 95% CI 0,51\u20131,05; Fibrinogen: SMD=0,66, 95% CI 0,08\u20131,23). Die Befunde f\u00fcr AQP4 und GFAP waren zwischen den Studien inkonsistent. Ein h\u00f6herer BMI war ebenfalls mit einem erh\u00f6hten Risiko f\u00fcr IIH verbunden (SMD=0,80, 95% CI 0,17\u20131,44). Die Studienqualit\u00e4t hatte keinen signifikanten Einfluss auf die Effektgr\u00f6\u00dfen. Erh\u00f6hte Spiegel von Nf-L und Fibrinogen sind mit einem erh\u00f6hten Risiko f\u00fcr IIH assoziiert und st\u00fctzen die Beteiligung von neuroaxonaler Sch\u00e4digung und Hyperkoagulabilit\u00e4t an der Pathophysiologie der Erkrankung. Gr\u00f6\u00dfere, multizentrische Studien unter Verwendung standardisierter Biomarker-Assays, Bildgebung und klinischem Ph\u00e4notyping sind erforderlich, um diese Ergebnisse zu validieren und die Entwicklung verbesserter diagnostischer und therapeutischer Strategien zu unterst\u00fctzen.\n\nID: 42453430\nTitle: Attenuating AAV-triggered innate immunity in the adult mouse nervous system via cGAS-STING pathway inhibition.\nAbstract: While adeno-associated virus (AAV)-mediated gene delivery has emerged as a promising therapeutic modality for neurological disorders, dose-dependent immune responses remain a critical barrier to clinical translation. Here we reveal the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway as a key mediator of innate immune activation following intracranial AAV administration. Through comparative analyses in genetic and pharmacological intervention models, we demonstrate that STING signaling mediates key neuroinflammatory sequelae including glia reactivation, cytotoxic T cell infiltration, and neuronal injury. Mechanistically, microglia serve as the predominant sentinels detecting AAV immunogenicity via cGAS-STING activation. Therapeutic inhibition of this pathway by either microglia depletion or antagonism of STING by small molecules significantly mitigates high-dose AAV9-induced neurotoxicity while enhancing transgene delivery efficacy. Our work delineates a unified mechanistic framework linking AAV-triggered DNA sensing to neuroinflammatory pathology, and provides two clinically actionable approaches to decouple therapeutic gene delivery from detrimental immune activation in nervous system targeted gene therapy.\n\nID: 42452748\nTitle: When LHON Mimics Demyelination: Area Postrema Syndrome in Biallelic DNAJC30 Variants.\nAbstract: Introduction: Biallelic pathogenic variants in DNAJC30 cause an autosomal recessive form of Leber hereditary optic neuropathy (LHONAR1), traditionally considered a mitochondrially transmitted disorder. The phenotypic spectrum of diseases linked to DNAJC30 includes isolated optic neuropathy, Leigh syndrome spectrum (LSS), and atypical LHON-plus. Case description: Here, we report a 13-year-old boy presenting symptoms of area postrema syndrome (APS), with recurrent vomiting, vertigo, nystagmus, and subacute visual deterioration with central scotoma. Ophthalmological examination revealed bilateral papilledema with telangiectatic vessels, while visual evoked potentials demonstrated severe bilateral optic pathway dysfunction. Brain magnetic resonance imaging (MRI) showed T2/FLAIR hyperintense lesions involving the area postrema and enhancement of the optic nerves, strongly suggesting seronegative neuromyelitis optica spectrum disorder (NMOSD). Extensive immunological and cerebrospinal fluid studies, including anti-aquaporin-4 (AQP4) and anti-MOG antibodies, were negative. High-dose corticosteroids and intravenous immunoglobulins resulted in only transient and incomplete improvement, followed by further visual decline. Additionally, laboratory tests detected elevated lactate plasma levels. Hence, whole-exome sequencing was performed, which identified a homozygous pathogenic DNAJC30 c.152A>G, p.(Tyr51Cys) variant, associated with LHONAR1. After initiation of idebenone therapy, the patient showed significant improvement in visual function, normalization of lactate levels, and complete resolution of the brainstem lesions on follow-up MRI. Conclusions: This case further expands the neuro-ophthalmic spectrum associated with DNAJC30 variants and suggests that DNAJC30-related disease may closely mimic seronegative NMOSD. We highlight that early genetic diagnosis is essential, as recognition of this mitochondrial etiology enables targeted therapy and may substantially improve clinical outcomes.\n\nID: 42449389\nTitle: Ferritin-ApoE nanocarrier for targeted therapy of neuromyelitis optica spectrum disorder in mice.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is a chronic inflammatory autoimmune disease affecting the central nervous system (CNS), characterized by anti-aquaporin 4 (AQP4) antibody-mediated damage to astrocytes, resulting in subsequent demyelination. Our prior work identified the protective effects of the apolipoprotein E130-149 (ApoE130-149) peptide in NMOSD mice by promoting astrocyte-microglia intercellular communication. However, its therapeutic potential is restricted due to the limited penetration of the blood-brain barrier (BBB) with systemic administration. Here, we designed a heavy-chain ferritin (HFn)-based nanocarrier containing the ApoE130-149 peptide (HFn-ApoE130-149), specifically engineered for CNS delivery. HFn-ApoE130-149 was constructed through genetic engineering by fusing the coding sequence of HFn with that of the ApoE130-149 peptide in a recombinant plasmid. An acute NMOSD mouse model was induced by transcranial co-injection of AQP4-IgG and human complement (hC) into the brain. The distribution of Cy5.5-labeled HFn-ApoE130-149 post intravenous injection was tracked using in vivo fluorescence imaging to confirm its presence in the brain and peripheral organs. Lesions in the brain were quantified using T2-weighted 7 Tesla magnetic resonance imaging (7T-MRI). Neuropathological features of NMOSD were evaluated by immunostaining of brain sections. Neuroinflammation and immune cell infiltration were analyzed via flow cytometry. The key signaling pathways regulated by HFn-ApoE130-149 were investigated through Western blot (WB) analysis. The interaction between HFn-ApoE130-149 and its receptors was validated through co-immunoprecipitation and visualized on microglia using proximity ligation assay (PLA). Finally, the therapeutic effect on spatial learning and memory was evaluated using the Morris water maze (MWM) test. The HFn-ApoE130-149 effectively crossed the BBB, attenuated lesion progression and demyelination, as well as preserved AQP4 expression and astrocytic integrity in NMOSD mice. The treatment induced a spatial and phenotypic restructuring of the astrocytic response, notably reducing excessive astrocyte accumulation around lesions while encouraging a proliferative and reparative phenotype. Furthermore, HFn-ApoE130-149 influenced microglial polarization towards an anti-inflammatory state, reducing infiltration of peripheral immune cells. Mechanistically, HFn-ApoE130-149 exerted its anti-inflammatory effects through the low-density lipoprotein receptor-related protein 1 (LRP1) -nuclear factor kappa B (NF-\u03baB) signaling axis in microglia. Functional binding of HFn-ApoE130-149 to LRP1 suppressed inhibitor of NF-\u03baB (I\u03baB\u03b1) phosphorylation, thereby inhibiting NF-\u03baB nuclear translocation and the subsequent release of pro-inflammatory cytokines, including interleukin-1 beta (IL-1\u03b2), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-\u03b1). Knocking down LRP1 reversed these effects, highlighting the importance of the LRP1-NF-\u03baB signaling axis in the nanotherapeutic's efficacy. Treatment with HFn-ApoE130-149 improved spatial learning and rescued memory deficits in NMOSD mice. This study demonstrates that the engineered nanodrug HFn-ApoE130-149 is a promising targeted therapy for alleviating NMOSD pathology by enhancing BBB penetration and suppressing neuroinflammation through the LRP1-NF-\u03baB signaling axis.\n\nID: 42448018\nTitle: Senegenin mitigates neuroinflammation, pyroptosis, and apoptosis in cerebral ischemia via inhibiting STING and downstream inflammatory pathway.\nAbstract: Ischemic stroke continues to be a major cause of mortality and persistent disability, with neuroinflammation at the central stage of cell death signaling. The stimulator of interferon genes (STING) pathway is emerging as a central driver of microglial activation and inflammatory damage. However, therapeutic strategies targeting this pathway are limited. We investigated the neuroprotective effects of senegenin, a bioactive natural compound, in a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model and N9 microglia subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Behavioral, histological, and biochemical analyses were performed to assess neurological outcomes, infarct volume, microglial activation, and neuroinflammatory response. Mechanistic studies evaluated the effects of senegenin on STING-TBK1-IRF3 signaling, NF\u03baB-dependent NLRP3 inflammasome activation, pyroptosis, and apoptosis. Molecular docking, dynamics simulations, and pharmacological validation with the STING agonist DMXAA were used to confirm direct STING inhibition. Senegenin treatment significantly improved neurological outcomes, decreased infarct volume, and preserved cortical and hippocampal neurons. It attenuated oxidative stress, reduced DNA damage, and inhibited microglial activation. Mechanistically, senegenin suppressed STING activation and downstream phosphorylation of TBK1 and IRF3, blocked NF-\u03baB/NLRP3-mediated pyroptosis, and inhibited apoptotic death by modulating Bcl2 and BAX expression. Molecular docking predicted stable binding of senegenin to STING, and DMXAA experiments confirmed direct inhibition of STING signaling as the mechanistic basis of its neuroprotective effects. This study demonstrates that senegenin confers potent neuroprotection in ischemic stroke by attenuating regulated cell death pathways through direct inhibition of STING, highlighting its ability as a promising therapeutic candidate for STING-targeted interventions in ischemic stroke and related neuroinflammatory disorders.\n\nID: 42446837\nTitle: Molecular Regulation of Pyroptosis in Alzheimer's Disease: Linking Neuroinflammation, Cell Death, and Therapeutic Targeting.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by profound cognitive decline, wherein chronic neuroinflammation plays a pivotal pathogenic role. Central to this inflammatory milieu is pyroptosis, a highly inflammatory form of programmed lytic cell death mediated by gasdermin proteins. This comprehensive review provides an in-depth synthesis of the cellular and molecular mechanisms underlying pyroptosis in AD. We detail the distinct roles of microglia as primary initiators responding to amyloid-beta (A\u03b2) and tau aggregates, alongside the specific vulnerabilities of neurons facing oxidative stress, astrocytes impacting metabolic support, and endothelial cells whose pyroptotic death contributes directly to blood-brain barrier disruption. At the molecular level, the priming and activation of the NLRP3 and NLRP1 inflammasomes by diverse triggers, including classical markers like A\u03b2, environmental neurotoxicants and metabolic stressors, converge on caspase-1 and caspase-8 activation. This cascade culminates in gasdermin D (GSDMD) and gasdermin E (GSDME) pore formation, leading to cellular lysis and the massive release of pro-inflammatory cytokines such as IL-1\u03b2 and IL-18. Furthermore, this paper explores the emerging and critical concept of PANoptosis, highlighting the intricate crosstalk between pyroptosis, apoptosis, and necroptosis within PANoptosome complexes triggered by mitochondrial dysfunction. We evaluate current and prospective therapeutic strategies, ranging from multi-target natural and traditional herbal remedies to advanced nanomedicine, synthetic small molecules, and epigenetic gene therapies. By integrating insights from blood-based pyroptosis-associated molecular signatures and advanced targeted drug delivery systems, we emphasize the critical need for personalized, multi-targeted approaches to successfully harness pyroptosis modulation in the clinical management and treatment of AD.\n\nID: 42444636\nTitle: Nanomedicines for modulating the gut-brain axis.\nAbstract: The dysregulation of the gut-brain axis affects cerebral function, contributing to the occurrence of neuropsychiatric symptoms and the worsening of neurodegenerative disorders. The main and direct nerve connection between the gut and the brain is the gastrointestinal vagus nerve, which is activated by pathogenic bacteria. In the course of inflammatory bowel diseases, microbial dysbiosis and intestinal inflammation compromise the epithelial barrier, leading to increased levels of circulating pro-inflammatory cytokines, which cross the blood-brain barrier and trigger neuroinflammation. Restoring microbiota balance and effective delivery of neuroactive metabolites to the brain is therefore expected to attenuate both neuroinflammation and neuropsychiatric symptoms. This article highlights some recent manuscripts that take advantage of nanomedical tools to achieve modulation of the gut-brain axis responses, thus developing promising therapies for inflammatory and neurodegenerative disorders.\n\nID: 42444415\nTitle: Engineered extracellular vesicles for targeted TREX1 delivery attenuate neuroinflammation after cerebral ischemia.\nAbstract: Ischemic stroke stands as a principal driver of global mortality and permanent functional deficits. Notably, the clinical efficacy of current interventions is severely restricted by post-ischemic neuroinflammation. Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA. Three-prime repair exonuclease 1 (TREX1), a cytosolic DNA exonuclease, negatively regulates STING signaling; however, efficient delivery of TREX1 to the ischemic brain remains a major challenge. Here, we engineered mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) as carriers for TREX1 delivery. This was accomplished by using a palmitoylation signal-fused construct (PALM-TREX1), which enables efficient loading of the protein into extracellular vesicles. The C1C2 domains of lactadherin and the RGD-4C peptide were combined into a single recombinant fusion protein, enabling EV surface functionalization for enhanced ischemic targeting via phosphatidylserine interaction. In a mouse model of middle cerebral artery occlusion (MCAO), RGD-modified TREX1-loaded EVs (RGD-EV-TREX1) preferentially accumulated in ischemic regions, suppressed STING pathway activation, and reduced microglial activation and pro-inflammatory cytokine expression. The reduction in neuronal DNA damage and apoptosis ultimately facilitated improved neurological functional recovery, positioning RGD-EV-TREX1 as a promising cell-free therapeutic strategy for ischemic stroke.\n\nID: 42443967\nTitle: Microglial mitophagy as an immunometabolic checkpoint in alzheimer's disease: linking mitochondrial quality control to neuroinflammation.\nAbstract: AD is a complex neurodegenerative disorder characterized by chronic neuroinflammation. Microglia, the brain's resident immune cells, centrally regulate AD pathophysiology. Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field.\n\nID: 42440589\nTitle: P2-engineered exosomes encapsulating curcumin alleviate cognitive decline in AD-like mice by improving microglia-related neuropathology.\nAbstract: Natural exosomes, as drug carriers, can deliver anti-inflammatory agents across the blood-brain barrier (BBB) to lesion sites in the brain, thereby demonstrating immense potential in the treatment of brain inflammation-related diseases. However, the application of natural exosomes is constrained by their poor targeting ability. Herein, we report a novel drug delivery system (P2-Exo-Cur) constructed by engineering exosomes to display the P2 peptide on their surface, thereby enabling targeted delivery of curcumin to microglia. Our results revealed that P2-Exo-Cur possesses a nanoscale membrane structure and can efficiently deliver curcumin to microglia both in vitro and in vivo. This technology provides a microglia-targeted delivery approach for anti-inflammatory agents such as curcumin, while overcoming the undesirable off-target effects that limit their efficacy. Furthermore, treatment of lipopolysaccharide (LPS)-induced inflammatory BV2 cell models with P2-Exo-Cur significantly suppressed the polarization of BV2 cells toward the M1 phenotype, as well as the secretion of pro-inflammatory cytokines. Finally, we also validated the excellent therapeutic potential of this technology in the 5xFAD mouse model. In conclusion, in this study, we for the first time constructed engineered exosomes that can specifically bind to the NCAM protein on microglia to achieve precise delivery of curcumin by expressing the P2 peptide on their surface, exerting beneficial effects in AD treatment without causing significant adverse effects. This strategy may offer a non-invasive and innovative therapeutic method for the management of brain inflammation-related diseases.\n\nID: 42439630\nTitle: Redox-Mitochondria-Immune Network Dysregulation in Schizophrenia: From Selective Cellular Vulnerability to Circuit Dysfunction.\nAbstract: Oxidative stress has been recognized as a repeatedly validated pathophysiological factor in schizophrenia, but its mechanistic role and translational relevance remain incompletely defined. Prior work has advanced redox dysregulation, neuroinflammation, and NMDA receptor hypofunction as a putative central hub in schizophrenia. This narrative review proposes an evidence-weighted redox-mitochondria-immune framework that integrates peripheral biomarkers, magnetic resonance spectroscopy, postmortem findings, and preclinical mechanisms while explicitly distinguishing established observations from candidate pathways. Existing studies support increased oxidative damage and altered antioxidant buffering in schizophrenia, particularly involving the glutathione system. However, these abnormalities are neither uniform across disease stages nor equally represented across patient subgroups, and may be markedly prominent only in certain biological subgroups. Mechanistically, redox imbalance may interact with mitochondrial bioenergetic deficits and innate immune signaling; however, pathway-specific links such as cGAS-STING activation, nitrosative/peroxynitrite stress, and GPx4-ferroptosis should currently be treated as testable extensions rather than validated human mechanisms in schizophrenia. Importantly, the pathological consequences of oxidative stress are unlikely to be cell-type neutral. Parvalbumin-positive interneurons and oligodendrocyte lineage cells are more vulnerable because of their high metabolic load, limited antioxidant buffering capacity, and lipid/iron-related susceptibility, thereby providing a mechanistic bridge to excitation-inhibition imbalance, myelin abnormalities, and reduced circuit synchrony. Microglial redox-inflammatory signaling may further exacerbate these processes. On the basis of this framework, we argue that the key for future research is not to continue demonstrating the universality of oxidative stress, but to improve the translational efficiency. Biomarker-guided stratification, stage-sensitive study designs, and cell-type-informed therapeutic strategies may therefore provide a more productive path toward redox-targeted interventions in schizophrenia.\n\nID: 42439335\nTitle: Gut Microbiota in Neuroinflammation, Neurodegenerative Disorders, and Neuropsychiatric Disorders: A Comprehensive Narrative Review.\nAbstract: Neurodegenerative and neuropsychiatric illnesses are characterized by neuroinflammation, which is driven by microglial activation, cytokine production, and breakdown of the blood-brain barrier (BBB). It is currently known that the gut microbiota plays an important role in modulating neuroimmune signaling, which in turn may trigger anxiety-like behaviors and depressive phenotypes through the microbiota-gut-brain axis. This review aims to integrate the most recent mechanistic knowledge on treatment strategies targeting the gut microbiota to modulate neuroinflammation. This review article discusses preclinical and clinical studies that investigated microbial composition, metabolite profiles, and host-microbe interactions involved in neuroinflammatory processes. However, special attention was given to signaling via the vagus nerves and bile acids, as well as to tryptophankynurenine metabolism and short-chain fatty acids (SCFAs). To examine the potential connection between the two, researchers used animal models such as germ-free animals and antibiotic-injected mice for fecal microbiota transplantation (FMT). This article defines dysbiosis as amplifying neuroinflammatory responses by altering microglial phenotypes, disrupting the blood-brain barrier, and triggering the production of pro-inflammatory cytokines. In contrast, microbiome diversity rehabilitation through the use of probiotics, prebiotics, synbiotics, and dietary modifications reduces neuroinflammatory markers and enhances cognitive and behavioral status. Clinical trials have shown considerable promise in diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), autism spectrum disorder (ASD), and depression. However, variability in treatment protocols, treatment resistance, and host-specific factors continue to pose significant challenges. This narrative review integrates mechanistic insights into microglial activation, cytokine signaling, blood-brain barrier regulation, vagal pathways, tryptophan metabolism, and short-chain fatty acids with emerging clinical evidence and therapeutic strategies, including probiotics, prebiotics, dietary modulation, and personalized microbiome-based interventions. Despite promising therapeutic potential, microbiome engineering faces important challenges, including safety concerns, lack of standardized intervention protocols, and substantial inter-individual variability in host-microbiome responses, which currently limit clinical translation. This review focuses on both neurodegenerative and neuropsychiatric disorders, examining shared neuroinflammatory mechanisms mediated by the gut-brain axis and evaluating microbiotatargeted therapeutic strategies across these disease categories. The review discusses both preventive strategies, including dietary modulation, prebiotics, and lifestyle-based microbiome interventions, as well as therapeutic approaches such as microbiota-targeted treatments aimed at mitigating neuroinflammation and disease progression.\n\nID: 42435423\nTitle: Targeted Degradation of STING by a Neutrophil Membrane-Coated Nanoplatform Suppresses Microglial Pyroptosis After Subarachnoid Hemorrhage.\nAbstract: Subarachnoid hemorrhage (SAH) is a life-threatening cerebrovascular disease in which neuroinflammation and neuronal death critically contribute to poor outcomes. Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH. This work establishes a novel biomimetic nanomedicine strategy for SAH therapy and opens new avenues for treating neuroinflammation-related disorders.\n\nID: 42433366\nTitle: Beyond AQP-4: convergent glymphatic-meningeal lymphatic dysfunction underlying multifactorial migraine pathogenesis.\nAbstract: The glymphatic system (GS) functions as a critical pathway for waste clearance from the brain, facilitating soluble protein and metabolite drainage. Recently, GS dysfunction has emerged as a potential contributor to migraine pathophysiology. GS operates similarly to the peripheral lymphatic system, dependent on astrocytes for metabolic waste removal. The clearance process involves cerebrospinal fluid entering the peri-arterial spaces, moving into the interstitial fluid via aquaporin-4 (AQP-4) channels at astrocyte feet, and eventually being drained into the cervical lymph nodes. As a downstream effector of the glymphatic system (GS), meningeal lymphatic vessels (MLVs) play a critical role in immune surveillance and regulation of cerebrospinal fluid (CSF) efflux. Calcitonin gene-related peptide (CGRP) is primarily involved in pain transmission and neuroinflammation within the nervous system. Within MLVs, CGRP modulates CSF outflow by promoting VE-cadherin rearrangement, thereby influencing pain responses in migraine mice. GS dysfunction has been observed in mice with migraine and may associate with cortical spreading depression (CSD)-induced transient perivascular space (PVS) closure. GS dysfunction has also been observed in the nitroglycerin (NTG)-induced mice migraine model. Consequently, this dysfunction might lead to the accumulation of CGRP, reactive oxygen species, and inflammatory factors, contributing to migraine initiation. In addition, CSD, a key mechanism in migraine aura, is postulated to induce transient PVS closure, disrupting GS flow. Further, impaired GS clearance would potentiate glutamatergic signaling and trigger neuroinflammation. Furthermore, AQP-4, a key component of GS, plays a crucial role in maintaining PVS function and modulating neuroinflammation. Reduced expression and impaired polarization of AQP4 may further impair GS clearance, leading to the accumulation of pathogenic mediators. GS dysfunction might be exacerbated by CSD and neuroinflammation. Further research is warranted to elucidate the underlying mechanisms and explore potential therapeutic targets aimed at restoring GS function in patients with migraine.\n\nID: 42430835\nTitle: Glymphatic dysfunction in neurodegeneration: From impaired clearance to mechanism-driven therapeutic innovation.\nAbstract: Glymphatic system refers to a system that involves perivascular clearance mechanisms within the brain, which are crucial for the elimination of neurotoxic proteins such as amyloid-\u03b2 (A\u03b2) and tau proteins in Alzheimer's disease (AD), \u03b1-synuclein in Parkinson's disease (PD), and mutant huntingtin (mHTT) in Huntington's disease (HD). There is mounting evidence suggesting that glymphatic dysfunction is an important cause of neurodegenerative diseases, characterized by failure of cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange due to abnormal clearance. Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation. Additionally, aberrant glymphatic flow acts as a crucial link between peripheral and central pathologies, amplifying neurodegeneration via altered solute transport and inflammation signaling. Glymphatic dysfunction has been found to be involved in diseases such as AD, PD and HD, thus indicating the widespread significance of glymphatic pathology. Therapeutically, targeting glymphatic function through modulation of AQP4 polarization, improving sleep-dependent clearance, and decreasing oxidative and inflammatory mechanisms may provide promising strategy for disease modification. This review provides a comparative and mechanistic overview of glymphatic dysfunction across AD, PD, and HD, highlighting peripheral-central interactions, biomarkers, imaging approaches, and therapeutic strategies, while addressing unresolved issues related to transport mechanisms, causality versus epiphenomenon, and translational limitations.\n\nID: 42427142\nTitle: Glutamate carboxypeptidase II activation in astrocytes mediates glymphatic impairment and cognitive vulnerability in the aging brain following surgery.\nAbstract: Perioperative neurocognitive disorder is a common and debilitating complication in the elderly, yet its cellular and molecular mechanisms in the aging brain remain poorly understood. Using aged mice, we examined the impact of abdominal surgery on cognition, glymphatic activity, and astrocyte function. Sex-dependent mechanisms were investigated by integrating single-cell RNA sequencing with astrocyte-specific genetic and pharmacological manipulation. Abdominal surgery induced male-specific deficits in recognition and spatial memory, reduced hippocampal glymphatic influx, and glutamate accumulation in aged mice. These changes were associated with male-specific upregulation of glutamate signaling in a distinct astrocyte subpopulation, enhanced astrocytic glutamate carboxypeptidase II (GCPII) activity, and loss of aquaporin-4 (AQP4) polarization. Astrocyte-specific GCPII knockdown rescued cognitive deficits and hippocampal glymphatic influx, consistent with pharmacological GCPII inhibition ameliorating glutamate levels, AQP4 polarization, and cognitive performance. These findings identify astrocytic GCPII-mediated glutamate dysregulation as a mechanism contributing to sex-specific postoperative cognitive vulnerability in aging.\n\nID: 42426383\nTitle: Immune Activation and Glial Dysfunction in Spinocerebellar Ataxias: From Cerebellar Landscape to Disease-Driven Mechanisms and Immunomodulation.\nAbstract: Spinocerebellar ataxias (SCAs) comprise a clinically and genetically heterogeneous group of autosomal dominant neurodegenerative disorders. Despite the recognized role of specialized cerebellar glia in cerebellar development and dysfunction, immune activation and non-immune glial responses remain understudied in SCAs. This narrative review compiles evidence from cellular, animal, and human models on the cerebellar immune landscape and the specific pathways that drive homeostatic failure and neuroinflammatory cascades across SCA subtypes. Microgliosis emerges consistently-and often early- as a generalized feature across the SCA spectrum, preceding neurodegeneration in several subtypes. Concurrently, reactive astrogliosis extends broadly, reflecting widespread macroglial surveillance and metabolic stress regulation throughout histologically preserved gray matter, with specialized homeostatic failure of Bergmann glia in SCA1, SCA2, and SCA7. Peripheral inflammation, manifests as early as the prodromal stage and correlates with the cognitive-affective deficits in SCA2 and associates with the mutation size in SCA3, positioning it as integral to pathogenesis rather than epiphenomenal. Diverse, partially shared signaling pathways converge on multi-lineage glial breakdown and reciprocal neuroimmune crosstalk. These mechanisms involve NF-\u03baB (SCA1,3,17), cGAS-STING (SCA2), TLR/MyD88 (SCA6), and JNK/c-Jun (SCA1,2,7). This review establishes abnormal reciprocal immune/non-immune glia crosstalk as a core pathogenic principle across SCAs, revealing novel therapeutic opportunities. In fact, targeting convergent signaling nodes such as NF-\u03baB, or JNK pathways, holds disease-modifying potential across multiple subtypes. Future research should prioritize standardized comparative studies, longitudinal analyses linking both inflammation and non-immune glial pathology to clinical progression, and clinical trials evaluating targeted immunomodulatory and glial homeostatic-supportive agents.\n\nID: 42425204\nTitle: Hyperbaric oxygen alleviates CFS-like cognitive impairment via PLA2G4A-linked glycerophospholipid metabolism.\nAbstract: Chronic fatigue syndrome (CFS) is frequently accompanied by persistent cognitive deficits and neuroinflammation, yet effective interventions remain limited. Here we tested whether hyperbaric oxygen (HBO) improves CFS-related cognitive impairment in mice and examined a glycerophospholipid-metabolic mechanism. CFS was induced by a 3-week multi-stressor paradigm, and mice received HBO (100% O2, 2.5 ATA, 60\u202fmin/session, 4 sessions/week for 3 weeks). HBO improved fatigue-/depressive-like behaviors and rescued spatial and recognition memory. Histology and ultrastructure analyses showed that HBO reduced hippocampal neuronal injury and preserved blood-brain barrier (BBB) integrity, accompanied by decreased pro-inflammatory cytokines and attenuated microglial activation. Untargeted LC-MS metabolomics revealed that HBO partially reversed CFS-associated metabolic shifts and enriched glycerophospholipid metabolism. Hippocampal Western blot further showed that HBO reduced CFS-associated elevation of PLA2G4A signaling. In parallel, PGE2 levels were decreased by HBO and by AACOCF3, supporting a PLA2G4A-related downstream inflammatory lipid mediator axis. In BV2 microglia and in vivo CFS mice, pharmacological PLA2G4A inhibition with AACOCF3 attenuated inflammatory and behavioral abnormalities, and subsequent HBO did not confer additional significant benefit. Together, these data support that HBO alleviates CFS-related cognitive impairment in this model, at least in part, through suppression of neuroinflammation involving a PLA2G4A-linked glycerophospholipid metabolic pathway.\n\nID: 42424917\nTitle: RGD-functionalized cannabidiol lipid nanoparticles improve brain delivery and alleviate cognitive and metabolic dysfunction via gut-brain axis modulation in an Alzheimer's disease model.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline and neuronal loss. Evidence links gut-brain axis dysfunction and metabolic disturbances to AD. Although cannabidiol (CBD) has neuroprotective effects, its use is limited by poor bioavailability and brain delivery. Arginylglycylaspartic acid (RGD)-functionalized, CBD-loaded lipid nanoparticles (CBD/LNP-RGD) were developed to enhance targeted delivery across the blood-brain barrier (BBB) via integrin \u03b1v\u03b23-mediated transcytosis. Cellular uptake and BBB permeability were evaluated in vitro. Anti-inflammatory and antioxidant effects were assessed in A\u03b2/LPS-induced models. In vivo efficacy was examined using cognitive-behavioral tests, including the novel object recognition and the Morris water maze. Metabolic parameters, histopathology, synaptic protein expression, and gut barrier integrity were also evaluated. CBD/LNP-RGD demonstrated a 3-fold increase in cellular uptake and a 65% enhancement in BBB transport compared to non-targeted formulations. Treatment significantly reduced pro-inflammatory cytokines (i.e., IL-6 and TNF-\u03b1, p\u202f<\u202f0.001) and intracellular reactive oxygen species (p\u202f<\u202f0.001). In vivo, CBD/LNP-RGD improved cognitive performance comparable to Donepezil (p\u202f<\u202f0.001). Additionally, it normalized glycemic control, insulin resistance, and triglyceride levels without hepatic or renal toxicity. At the tissue level, CBD/LNP-RGD reduced A\u03b2 and tau pathology, restored short-chain fatty acids, preserved hippocampal neuronal integrity, and upregulated synaptophysin and PSD-95 proteins. Enhanced intestinal barrier function was evidenced by increased expression of tight junction proteins ZO-1 and occludin. CBD/LNP-RGD represents a multifunctional nanotherapeutic platform that improves brain delivery and exerts neuroprotective, anti-inflammatory, antioxidant, and metabolic regulatory effects. Its ability to modulate both central pathology and the gut-brain axis highlights its potential as a disease-modifying strategy for Alzheimer's disease.\n\nID: 42421041\nTitle: Advances in electroacupuncture for perioperative neurocognitive disorders: mechanisms and clinical evidence.\nAbstract: Perioperative neurocognitive disorders (PND), including postoperative delirium, delayed neurocognitive recovery, and postoperative cognitive dysfunction, are common complications in older surgical patients and are associated with impaired recovery, reduced quality of life, and increased postoperative morbidity. Current management remains largely supportive and preventive, and effective targeted therapies are still lacking. Electroacupuncture (EA), as a minimally invasive neuromodulatory intervention, has attracted increasing attention because of its potential multi-target regulatory effects. This review summarizes current mechanistic and clinical evidence regarding EA for PND. Preclinical studies suggest that EA may modulate several interacting pathological processes, including neuroinflammation, oxidative stress, autophagy dysfunction, ferroptosis, mitochondrial injury, microbiota-gut-brain axis dysregulation, and hippocampal synaptic plasticity. Recent PND/POCD animal studies further support EA-related regulation of NLRP3 inflammasome activation, cGAS-STING signaling, SIRT1/NRF2/GPX4-mediated ferroptosis, AMPK/SIRT1/FOXO1/PINK1/Parkin-related autophagy pathways, and MAPK-related synaptic plasticity. Clinical studies and meta-analyses suggest that EA and related acupoint-based electrical stimulation techniques may reduce early postoperative cognitive decline and improve short-term cognitive outcomes in older surgical patients. However, the overall evidence remains limited by heterogeneous stimulation protocols, variable acupoint prescriptions, incomplete blinding, short follow-up, and reliance on cognitive screening scales. Several proposed mechanisms are still partly inferred from non-PND models. Future studies should use standardized EA protocols, clinically relevant PND models, dynamic mechanistic assessments, and adequately powered sham-controlled trials to clarify the therapeutic role of EA in PND.\n\nID: 42412752\nTitle: Chronic intermittent hypoxia impairs glymphatic function in male mice through ENT-dependent adenosine dysregulation.\nAbstract: Chronic intermittent hypoxia (CIH), a defining feature of obstructive sleep apnea, is strongly associated with cognitive impairment and increased risk of neurodegenerative disease, yet the underlying mechanisms linking hypoxic stress to disrupted brain homeostasis remain poorly defined. Impaired glymphatic clearance has been reported in patients with obstructive sleep apnea, but whether and how intermittent hypoxia directly alters glymphatic function is unknown. Here, we investigated the effects of acute and chronic intermittent hypoxia on cerebrospinal fluid-interstitial fluid exchange in male mice and examined the molecular mechanisms governing these effects. Using tracer-based influx and efflux assays, in vivo two-photon imaging, behavioral testing, and genetic and pharmacological manipulation, we show that intermittent hypoxia exerts a duration-dependent, biphasic effect on glymphatic function. Acute exposure transiently enhanced glymphatic influx and efflux, whereas prolonged CIH progressively impaired glymphatic transport, disrupted perivascular aquaporin-4 (AQP4) polarization, reduced vascular pulsatility, and impaired spatial working memory. CIH was associated with reduced extracellular adenosine levels, suppression of cerebral energy metabolism, and altered expression of equilibrative nucleoside transporters (ENTs). Genetic ablation of AQP4 abolished CIH-induced glymphatic impairment, confirming its essential role in hypoxia-induced glymphatic dysfunction. Importantly, pharmacological inhibition or genetic deletion of ENT1 and deletion of ENT2 restored adenosine availability, normalized AQP4 polarization and vascular dynamics, and rescued glymphatic dysfunction and cognitive deficits under CIH. These findings identify ENT-dependent dysregulation of adenosine signaling as a key mechanism by which chronic intermittent hypoxia compromises glymphatic clearance, providing mechanistic insight into how sleep-disordered breathing disrupts brain waste removal and cognitive function.\n\nID: 42411487\nTitle: The Role of Hippocampal Microglial cGAS-STING Signaling Pathway in Postoperative Cognitive Dysfunction in Diabetic Mice.\nAbstract: This study aimed to determine whether activation of the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway within hippocampal microglia contributes to postoperative cognitive dysfunction (POCD) in a diabetic mouse model. Diabetes was induced using a high-fat, high-sugar (HFHS) diet combined with streptozotocin (STZ). Diabetes was induced in C57BL/6J mice using an HFHS diet followed by STZ. POCD was modeled via tibial fracture surgery under general anesthesia. Cognitive function was assessed using the Open Field Test, Y-maze, and contextual fear conditioning. cGAS-STING pathway activation was evaluated by western blot for cGAS and STING expression. Microglial activation was assessed by co-localization of Iba-1 and CD68 by immunofluorescence, and the co-localization of STING with Iba-1 in the hippocampus was examined by immunofluorescence. Hippocampal neuroinflammation was quantified by enzyme-linked immunosorbent assay (ELISA) for interleukin-1beta (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1). Neuronal injury and apoptosis were evaluated by Nissl staining and western blot for cleaved caspase-3. Compared to non-diabetic controls, diabetic mice exhibited cognitive impairments, which were more pronounced in those that underwent surgery. This was accompanied by significant hippocampal neuronal loss, upregulated cleaved caspase-3 expression, and elevated IL-1\u03b2 and TNF-\u03b1 levels. Furthermore, diabetic mice that underwent surgery displayed increased expression of microglial activation markers (Iba-1 and CD68) and evidence of cGAS-STING pathway activation in the hippocampus. Immunofluorescence co-localization experiments further suggested a predominant association of this pathway with the microglial marker Iba-1. These findings suggest that surgery-associated overactivation of the microglial cGAS-STING pathway in the hippocampus may exacerbate neuroinflammation and neuronal injury, thereby contributing to cognitive decline in diabetic mice.\n\nID: 42411430\nTitle: Glymphatic-Related Alterations in Major Depressive Disorder and Treatment-Resistant Depression: Imaging Proxies, Mechanistic Links, and Therapeutic Opportunities.\nAbstract: Major depressive disorder is increasingly conceptualized as a condition involving brain network dysfunction, neuroimmune imbalance, sleep-circadian disruption, hypothalamic-pituitary-adrenal (HPA)-axis dysregulation, monoaminergic arousal instability, and impaired synaptic plasticity. In parallel, the glymphatic system has emerged as a plausible integrative mechanism linking these domains, because it is a glia-dependent pathway supporting cerebrospinal fluid-interstitial fluid exchange and metabolic-waste clearance, with activity strongly modulated by deep non-rapid eye movement (NREM) sleep. This narrative review synthesizes evidence that glymphatic-related magnetic resonance imaging (MRI) proxies, particularly diffusion tensor imaging along the perivascular space (DTI-ALPS), are altered in depression, while emphasizing that DTI-ALPS is an indirect marker of perivascular diffusion rather than a direct measure of glymphatic flow. We define four key research gaps: scarcity of treatment-resistant depression (TRD)-specific cohorts, regional and technical heterogeneity across MRI studies, and uncertainty about causal direction relative to sleep disturbance and inflammation. Altered indices appear to relate to fatigue, psychomotor retardation, cognitive impairment, rumination, suicidality, systemic inflammation, oxidative stress, and HPA-axis dysregulation. We integrate opposite-direction findings, including elevated ALPS in drug-naive somatic depression, into a state- and subtype-dependent working model rather than a unidirectional dysfunction framework. Therapeutic implications are organized by target specificity, including sleep-dependent clearance, perivascular exchange, aquaporin-4 (AQP4) polarization, vascular pulsatility, and neuroimmune modulation. We propose falsifiable predictions and negative-control analyses to distinguish a glymphatic-related model from additive effects of insomnia, inflammation, and vascular risk. Overall, the current evidence supports a cautious translational framework for biomarker-informed trials in TRD-relevant phenotypes rather than a validated diagnostic biomarker.\n\nID: 42411218\nTitle: Exploring Neurological Disorder Therapeutics: The Progress and Future Prospects of Proteins and Peptides Derived from Blue Foods.\nAbstract: Neurological illnesses continue to be a major global health challenge and require novel and safe therapeutic strategies. Blue foods like marine fish, algae, and invertebrates consist of many bioactive proteins/peptides that might provide multiple benefits for maintenance of a healthy brain, including neuroprotection, reduction of inflammation, and reduction of oxidative stress. This review looks at both recent advances made with blue food bio-molecules and their potential future roles in therapeutic targeting for neurological disorders. This study is designed as a narrative review, aiming to comprehensively summarize and critically analyze existing literature on marine-derived bioactive peptides and their neuroprotective potential. Literature searches were conducted from January 2009 to March 2025 using PubMed and other biomedical databases. Available preclinical evidence suggests that marine-derived proteins and peptides may exert neuroprotective effects through multiple mechanisms, including activation of antioxidant defense pathways via Nrf2-mediated signaling, modulation of NF-\u03baB-associated neuroinflammatory responses, regulation of serotonergic and dopaminergic neurotransmission, and attenuation of amyloid-\u03b2 aggregation. Experimental studies conducted in animal models have reported improvements in cognitive performance, reductions in oxidative stress biomarkers, and decreased production of pro-inflammatory cytokines following administration of marine protein hydrolysates. Clinical translation of marine-derived bioactive peptides remains challenging due to the following factors: standardization of extraction, bioavailability, batch-to-batch variability, allergenic potency, and complex regulatory requirements. Ongoing new approaches using nano-formulation, synthetic biology, and Artificial Intelligence (AI) in the discovery of peptides hold the promise of enhancing their stability, targeting, and scalability. However, in order to validate the therapeutic utility of these approaches, it will require large, well-designed clinical studies.\n\nID: 42406535\nTitle: Fatty Acid Binding Protein 5 Mediates Astrocytic Pyroptosis and Neuroinflammation in Epilepsy via cGAS/STING Pathway.\nAbstract: Pyroptosis is an inflammatory type of programmed cell death that may contribute to epilepsy initiation and progression through neuroinflammation. Fatty acid binding protein 5 (FABP5), a lipid chaperone, has been implicated in chronic inflammation. However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells. Deletion of astrocytic Fabp5 significantly attenuated pyroptosis, neuronal loss, and seizure activity in epilepsy. Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis. Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Pharmacological inhibition of mitochondrial fatty acid import recapitulated these protective effects. In contrast, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. Collectively, these findings revealed the regulatory role of FABP5-cGAS-STING-pyroptosis axis in the progression of epilepsy and highlighted the promising potential of astrocytic FABP5 as a therapeutic target for epilepsy.\n\nID: 42404896\nTitle: Comparison of clinical and laboratory characteristics of neuromyelitis optica spectrum disorder with or without anti-connective tissue antibodies: an 18-month cohort follow-up.\nAbstract: This study aimed to explore the significance of anti-connective tissue antibodies in the clinical diagnosis and evaluation of neuromyelitis optica spectrum disorder (NMOSD). Demographic and clinical data from 205 patients with aquaporin-4 immunoglobulin G (AQP4-IgG)-positive NMOSD were collected. Variables included sex, age, clinical symptoms/signs, connective tissue antibody status, inflammatory markers, cerebrospinal fluid (CSF) cell counts/oligoclonal band status, spinal cord lesion location/length, Expanded Disability Status Scale scores at onset and first relapse (18-month follow-up), and time to first relapse. Among the 205 patients, 108 (52.7%) were positive for anti-connective tissue antibodies (CTD abs+). Compared with anti-connective tissue antibodies (CTD abs-) patients, the CTD abs+ group had higher lymphocyte counts (1.82 \u00b1 0.14 vs. 1.73 \u00b1 0.07, p < 0.01), higher monocyte-to-lymphocyte ratios [0.27 (0.2) vs. 0.24 (0.16), p = 0.037], and higher CSF white blood cell counts [10 (22) vs. 6 (18)/106/L, p = 0.035]. They also showed a higher rate of oligoclonal band positivity (27.78% vs. 10.31%, p\u00a0=\u00a00.002), a higher proportion of patients with an increased 24-hour intrathecal synthesis rate (54.6% vs. 40.2%, p\u00a0=\u00a00.039), and higher CSF immunoglobulin levels [5.755 (6.37) vs. 4.15 (3.53) mg/dL, p < 0.001] at initial onset. No significant differences were observed between the CTD abs+ and CTD abs- groups in the distribution of lesions or the length of affected spinal cord vertebral segments at initial onset. However, patients in the CTD abs+ group had higher Expanded Disability Status Scale scores at first relapse and a higher annualized relapse rate over the 18-month follow-up period(p <\u00a00.05for both). In summary, among AQP4-IgG-positive patients with NMOSD, CTD abs+ was associated with higher lymphocyte counts, a higher MLR, higher CSF white blood cell counts, higher CSF immunoglobulin levels, a higher 24-hour intrathecal IgG synthesis rate, and higher OCB positivity. CTD abs positivity may therefore indicate a more severe inflammatory profile; however, it does not appear to predict earlier relapse, but does appear to predict a higher annualized relapse rate.\n\nID: 42484938\nTitle: The Clearance-Centered Bottleneck in Alzheimer's Disease: From Coupled Glymphatic-Lymphatic Circuits to Therapeutic Opportunities.\nAbstract: While anti-amyloid-beta (A\u03b2) monoclonal antibodies have achieved substantial success in reducing plaque burden, their modest clinical impact highlights an \"efficacy ceiling\" that necessitates a re-evaluation of Alzheimer's disease (AD) pathogenesis. This review proposes a shift from an amyloid-centered paradigm to a \"clearance-centered bottleneck\" framework, conceptualizing brain homeostasis as a coupled glymphatic-lymphatic circuit. We identify three critical rate-limiting nodes-entry, transit, and exit-that govern this circuit. These nodes fail through distinct mechanisms: arterial stiffening (entry), aquaporin-4 (AQP4) depolarization (transit), and cerebral amyloid angiopathy with impaired meningeal lymphatic drainage (exit). This multilevel failure creates a self-sustaining \"neuroimmune stalemate\"-a state in which trapped antigens and inflammatory mediators perpetuate glial reactivity that further degrades the very clearance infrastructure needed to resolve it. Distinct from prior reviews of glymphatic dysfunction in isolation, this review contributes four interlinked advances: an integrated glymphatic-lymphatic coupled-circuit framework; a bidirectional immune-clearance crosstalk model; a critical appraisal of imaging endpoints graded by trial-readiness; and a combination therapy roadmap. To overcome the current therapeutic plateau, we advocate for multinode interventions that combine amyloid-targeting therapies with clearance-enhancing agents, supported by a readiness-tiered imaging strategy-standardized proxies such as DTI-ALPS and PVS burden as enrichment/secondary endpoints and dynamic contrast-enhanced MRI for mechanistic proof-of-concept.\n\nID: 42483938\nTitle: The effect of the Mediterranean diet combined with physical activity on cognitive function in older adults: a scoping review.\nAbstract: Cognitive impairment and dementia are rapidly increasing among older adults, with limited pharmacological treatments available. Modifiable lifestyle factors, particularly diet and physical activity, are promising preventive targets. Although the Mediterranean diet and regular exercise individually benefit cognition, their combined effects and underlying mechanisms remain poorly synthesised. The systematic review followed PRISMA-ScR guidelines and involved database searches on PubMed, Embase, Web of Science, Cochrane, and CNKI. Study inclusion criteria were defined using the PICO framework. The Mediterranean diet supplies polyphenols and fatty acids that reduce oxidative stress and inflammation, and support neurotrophic and neuroendocrine functions, thus protecting the brain. Meanwhile, physical activity boosts cerebral blood flow, improving antioxidant delivery and stimulating neurotrophic factors like BDNF, IGF-1, and VEGF to enhance brain plasticity. Together, these approaches act synergistically to balance energy metabolism, lower inflammation, and activate antioxidant defenses, thereby preserving brain homeostasis and boosting cognitive function. Evidence suggests a synergistic effect of the Mediterranean diet and physical activity in preserving cognitive function in older adults. The diet directly supports cognitive health and provides essential nutrients for exercise-induced neuroregeneration. Physical activity, in turn, increases cerebral blood flow, improving nutrient delivery and stimulating neurotransmitter release. This interaction enhances brain plasticity, establishing a virtuous cycle between nutrition, exercise, and cognitive health.\n\nID: 42471087\nTitle: Neurovascular unit senescence as a driver of blood-brain barrier dysfunction in Alzheimer's disease\uff1aMechanisms, consequences, and therapeutic implications.\nAbstract: Alzheimer's disease (AD) is a common age-related neurodegenerative disorder (NDD), with ageing as its primary risk factor. Cellular senescence, characterized by permanent cell-cycle arrest, apoptosis resistance and acquisition of the senescence-associated secretory phenotype (SASP), is the cellular hallmark of ageing. Recent evidence indicates that blood-brain barrier (BBB) dysfunction precedes cognitive decline and pathological protein deposition, representing an early event in AD, with the neurovascular unit (NVU) providing the structural and functional basis of the BBB. Mounting evidence shows that the core NVU cells-brain microvascular endothelial cells (BMECs), pericytes and astrocytes-enter senescence under AD-related conditions. SASP factors released by these cells disrupt BBB junction proteins and trans-BBB transport systems, and propagate senescence within the NVU via paracrine signaling. Peripheral inflammatory mediators and immune cells then traverse the compromised BBB, aggravating AD pathology, while accumulating A\u03b2, tau and reactive oxygen species (ROS) reciprocally accelerate NVU senescence, constituting a proposed vicious cycle. At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury. From the NVU perspective, this review systematically examines how cellular senescence drives BBB dysfunction and AD progression, clarifies the role of cGAS-STING as a molecular node, and discusses therapeutic strategies targeting NVU senescence to preserve BBB integrity, aiming to offer new insights into AD mechanisms and treatment.\n\nID: 42470822\nTitle: Recent advances in methotrexate pharmacology and potential therapeutic uses in age-related cardiometabolic and neurodegenerative diseases.\nAbstract: Experimental and clinical evidence continues to accumulate, supporting the critical role of dysregulated inflammation, immunity, and redox signaling in the pathophysiology of various age-related cardiometabolic and neurodegenerative diseases. While ongoing research is investigating novel anti-inflammatory and immunomodulatory therapies for such conditions, available antirheumatic drugs may serve a similar purpose. One such drug, methotrexate, has been successfully used at high doses since the 1940s as an anticancer agent and, more recently, at lower doses in patients with autoimmune diseases. Although the effects of methotrexate have traditionally been attributed to its antiproliferative activity via folic acid modulation, additional targets have been identified, including AMP-activated protein kinase, Janus kinase/signal transducer and activator of transcription, high mobility group box 1 protein, the gut microbiota, and additional pharmacological effects of adenosine, a key mediator of methotrexate. The beneficial effects of modulating these targets on downstream inflammatory and immune pathways, cellular senescence, and vascular, metabolic, and brain homeostasis have been increasingly investigated in experimental models. Furthermore, studies conducted over the past 20 years suggest an association between low-dose methotrexate and a decreased risk of certain age-related cardiometabolic and neurodegenerative diseases, particularly in patients with autoimmune conditions. The results of these studies support the potential protective role of methotrexate against age-associated cardiometabolic and neurodegenerative diseases through multiple mechanisms, unlike targeted immunomodulatory and anti-inflammatory drugs, thereby providing a robust framework for investigating its repurposing in future intervention studies. SIGNIFICANCE STATEMENT: New treatments are essential to address the burden of age-related diseases. The important roles of dysregulated inflammation, immunity, and redox signaling in these conditions have spurred research into developing new therapies or repurposing existing drugs to target these dysfunctions. The disease-modifying antirheumatic drug methotrexate has shown potential protective effects against cellular senescence and certain age-related cardiometabolic and neurodegenerative diseases. This knowledge will encourage further research into the repurposing of methotrexate for the treatment of these diseases.\n\nID: 42467129\nTitle: Identification of divergent organ-specific gene and protein expression signatures for mitochondrial function, inflammatory response, and proteostasis in the liver and brain in the rotenone-induced rat model of Parkinson's disease.\nAbstract: Emerging evidence suggests that peripheral organs, particularly the liver, may influence brain homeostasis and neurodegenerative diseases. This study investigates the differential expression of Parkinson's disease (PD)-related, oxidative stress, and inflammatory genes in the liver and brain of six-week-old male albino Wistar rats (250-300\u00a0g) subchronically exposed to rotenone (ROT, 1.3\u00a0mg/kg/day, 35 days, b.w.), a pesticide commonly used to model PD. Relative expression levels were measured using quantitative real-time PCR (RT-qPCR) and western blot. Genes involved in mitophagy (Parkin (PARK2), p\u2009=\u20090.0039), oxidative stress response (Parkinson's disease protein (DJ-1), p\u2009=\u20090.0209), lysosomal function (Low-density lipoprotein receptor-related protein-1 (LRP1), p\u2009=\u20090.0418; ATPase cation transporting 13a2 (ATP13a2), p\u2009=\u20090.0308), and inflammation (Tumour necrosis factor alpha (TNF-\u03b1), p\u2009=\u20090.0171) were found upregulated in the brain of ROT-induced rats as compared to control rats, and were also significantly higher than in the liver (p\u2009<\u20090.05). In contrast, significantly higher phosphatase and tensin homolog-induced kinase 1 (PINK1) expression was found in the liver as compared to the brain (p\u2009=\u20090.0198). Notably, these inter-organ differences and transcriptional shifts were absent in the controls. Moreover, the liver exhibited distinct molecular responses, including significant downregulation of ATP13a2 and SNCA (Encoding alpha-synuclein) and overexpression of NFe2-like basic leucine zipper transcription factor 2 (NFe2l2), compared to control rats (p\u2009<\u20090.05). Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-\u03baB), and interferon gamma (IFN-\u03b3) showed no significant changes in either tissue (p\u2009>\u20090.05). These findings demonstrate that distinct molecular alterations in the liver and brain following ROT treatment, including differences in the regulation of genes associated with mitophagy, oxidative stress, proteostasis, and inflammation. Our findings demonstrate tissue-specific molecular associations in the liver and brain within the ROT-induced PD model, providing new insights into the pathophysiology of neurodegeneration and identifying potential biomarkers and therapeutic targets for future studies.\n\nID: 42463967\nTitle: In vivo multimodal PET/MRI imaging and plasma biomarkers implicate glymphatic dysfunction linking neuroinflammation to tau pathology in the early Alzheimer's disease continuum.\nAbstract: Neuroinflammation is a key factor contributing to cognitive decline in Alzheimer's disease (AD). This study aims to investigate the mechanistic associations among neuroinflammation, glymphatic dysfunction, tau pathology, and cognitive decline in AD spectrum. The study included 355 participants from the Alzheimer's Disease Neuroimaging Initiative (ADNI) and a supportive cohort of 59 individuals from Wuhan Union Hospital (WHUH). Tau pathology was quantified using 18F-AV1451 positron emission tomography (PET). Glymphatic function was estimated through diffusion tensor image analysis along the perivascular space (DTI-ALPS). Neuroinflammation was assessed via plasma glial fibrillary acidic protein (GFAP) in two cohorts and translocator protein (TSPO) PET imaging with 18F-DPA-714 in supportive cohort. Correlation analyses and mediation models were employed to evaluate the directional relationships among tau deposition, inflammation, glymphatic function, and cognition. Higher levels of inflammation were significantly associated with lower DTI-ALPS index (\u03b2 = -0.171, P\u2009=\u20090.046), which in turn was associated with higher tau burden (\u03b2\u2009=\u20090.162, P\u2009=\u20090.010). Path analysis revealed significant indirect associations linking neuroinflammation to cognitive performance through glymphatic dysfunction and tau pathology, with total indirect effects of -\u20090.165 (95% CI, -\u20090.266 to -\u20090.105) in ADNI and -\u20090.143 (95% CI, -\u20090.386 to -\u20090.013) in WHUH. These findings support a hypothesized inflammation-glymphatic-tau pathway rather than a definitive causal cascade. Our findings are consistent with a hypothesized inflammation-glymphatic-tau association in which greater neuroinflammation is linked to reduced glymphatic function and higher regional tau burden, particularly in preclinical and prodromal stages. This study obtained ethical approval from the Institutional Review Committee of Nanjing Drum Tower Hospital (ChiCTR-BRC-17011316, date:20170506; ChiCTR1900022526, date:20190415).\n\nID: 42451686\nTitle: Decoding the CSF Proteomic Signature of Idiopathic Normal Pressure Hydrocephalus: A Systematic Review.\nAbstract: Idiopathic normal pressure hydrocephalus (iNPH) is a potentially reversible neurological disorder characterized by gait disturbance, cognitive impairment, and urinary incontinence; however, its diagnosis and prediction of shunt responsiveness remain challenging. This systematic review aimed to synthesize current evidence on cerebrospinal fluid (CSF) proteomic biomarkers in iNPH and to identify molecular patterns with diagnostic and prognostic relevance. A PRISMA-guided search of PubMed, Web of Science, and Google Scholar identified 14 eligible studies comprising 1171 iNPH patients. Proteomic analyses revealed substantial heterogeneity in study design and detected proteins; however, consistent patterns emerged. iNPH is associated with upregulation of inflammatory and extracellular matrix-related proteins and relative downregulation of synaptic and neuronal markers. Neurodegenerative proteins, including amyloid-\u03b2, tau, and neurofilament light chain, demonstrated value in differentiating iNPH from comorbid neurodegenerative diseases and in predicting response to ventriculoperitoneal shunting (VPS). These findings support a multifactorial model of iNPH involving impaired glymphatic clearance, neuroinflammation, blood-brain barrier dysfunction, and mechanical axonal stress. Multidimensional biomarker profiles, rather than single proteins, appear to provide the greatest clinical utility, highlighting the need for standardized proteomic panels and integrative predictive models. However, given the substantial heterogeneity of the included studies and the predominantly exploratory nature of current proteomic evidence, the identified proteins should be interpreted as candidate biomarkers rather than clinically validated diagnostic or prognostic tools. Multidimensional biomarker profiles appear biologically plausible and may offer greater explanatory value than single proteins, but their clinical utility requires validation in standardized prospective cohorts. The authors therefore propose a conceptual iNPH proteomic \"Vulnerability Model\" integrating CSF biomarkers to reflect the balance between reversible and irreversible pathology; this is currently a hypothetical model that requires rigorous statistical and clinical validation through large-scale prospective cohort studies before it can fulfill its potential for improving patient stratification and prediction of postoperative outcomes.\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: 42437380\nTitle: Brain clearance physiology in traumatic brain injury: From disruption to therapeutic potential.\nAbstract: \n\nID: 42421497\nTitle: Emerging viral infections: role of flavivirus NS1-mediated rewiring of PRR signaling.\nAbstract: Flaviviruses, including Dengue, West Nile, Zika, and Japanese encephalitis viruses, are arthropod-borne RNA viruses that pose an increasing global health threat. This review summarizes the role of nonstructural protein 1 (NS1), a multifunctional glycoprotein found in intracellular and secreted forms, as a key regulator of innate immunity. NS1 modulates several pattern recognition receptor pathways, including TLRs, RLRs, SR-B1-related mechanisms, and inflammasome platforms, thereby altering cytokine and interferon responses. Its effects are virus- and context-dependent. WNV NS1 inhibits TLR3/TRIF signaling, reducing IRF3 activation, type I interferon production, and interferon-stimulated gene expression. In contrast, DENV NS1 is linked to inflammatory signaling, particularly through TLR4. At the cytosolic level, NS1 from DENV, WNV, and ZIKV disrupts RIG-I/MDA5-MAVS signaling and weakens IFN-\u03b2 induction. NS1 also affects inflammasome pathways: DENV promotes IL-1\u03b2 release through a CD14-dependent mechanism, ZIKV suppresses cGAS-mediated antiviral signaling, and JEV promotes NLRP3 inflammasome assembly. Overall, NS1 selectively dampens interferon-mediated antiviral defenses while sustaining or enhancing inflammation, contributing to endothelial dysfunction, neuroinflammation, and severe disease.\n\nID: 42413140\nTitle: From diabetic foot to dementia: A neurovascular continuum linking systemic diabetic vasculopathy, cerebral small vessel disease, and glymphatic dysfunction.\nAbstract: Diabetes mellitus, particularly type 2 diabetes mellitus (T2DM), is increasingly recognized as a major risk factor for cognitive decline and dementia. Epidemiological studies consistently demonstrate that individuals with diabetes exhibit a significantly elevated risk of both vascular cognitive impairment and Alzheimer's disease [1,2]. Beyond hyperglycemia, systemic vascular dysfunction has emerged as a central mechanism underlying diabetes-related brain injury. Diabetes induces widespread vascular alterations, including endothelial dysfunction, arterial stiffening, oxidative stress, and chronic low-grade inflammation [3,4]. These processes affect both peripheral and cerebral circulation and may contribute to the development of cerebral small vessel disease (CSVD), a major substrate of cognitive decline [10-12]. Increased arterial stiffness may impair the Windkessel effect and facilitate the transmission of excessive pulsatile energy into fragile cerebral perforating arteries, thereby promoting microvascular injury and white matter damage [13-17]. In addition, diabetes-associated disruption of the neurovascular unit (NVU) may lead to blood-brain barrier dysfunction, neuroinflammation, and neuronal injury [20-30]. Impairment of the glymphatic system responsible for the clearance of metabolic waste products such as amyloid-\u03b2 and tau may further contribute to neurodegenerative processes [31-41]. In this review, we propose a \"systemic vascular continuum\" linking peripheral diabetic vasculopathy, cerebral small vessel disease, neurovascular unit dysfunction, and glymphatic impairment. Within this framework, diabetic foot ulcer (DFU) is presented as a clinically visible peripheral phenotype and surrogate marker of advanced systemic vascular injury rather than a direct causal factor [5-9]. This integrative model provides a conceptual framework for understanding diabetes-associated cognitive impairment and highlights vascular-targeted preventive and therapeutic strategies as promising approaches for risk stratification and intervention.\n\nID: 42404802\nTitle: Region-specific features of early glial activation and Aquaporin-4 dysregulation in conditional mouse models of TDP-43 proteinopathies.\nAbstract: Aggregation and cytoplasmic mislocalization of TDP-43 are key features of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Neuroinflammatory processes mediated by glial cells play crucial roles in the pathophysiology of these and other diseases, defined as TDP-43 proteinopathies. Here, we characterized region-specific glial activation in two conditional mouse models: hTDP-43-WT (overexpressing nuclear wild-type human TDP-43) and hTDP-43-\u0394NLS (expressing cytoplasmic TDP-43 with altered nuclear localization signal) following 1 month of transgene expression. Immunofluorescence analysis revealed distinct patterns of microglial activation across brain regions. hTDP-43-WT mice exhibited significant microgliosis in motor (MC) and somatosensory (SSC) cortices and hippocampal dentate gyrus (DG) with pronounced morphological alterations (i.e. increased soma size). Sholl analysis demonstrated reduced branching length and complexity in MC, SSC, and hippocampal subfields. hTDP-43-\u0394NLS mice displayed more pronounced microglial activation in hippocampal regions (CA1, DG) compared to cortical areas, with significant increases in microglial density. Additionally, we observed region-specific cortical astrocytosis in both models, suggesting coordinated glial reactivity. hTDP-43-\u0394NLS mice showed decreased polarization of astrocytic water channel Aquaporin-4 (AQP4) around vascular structures in SSC and hippocampal CA1/DG. The changes in AQP4 localization, which is critical for glymphatic function, support the hypothesis that this waste clearance system for the brain is altered in TDP-43 proteinopathies. These findings demonstrate that these different animal models of ALS/FTD induce distinct neuroinflammatory signatures, potentially contributing to the region-specific vulnerability observed in these diseases. Our data provide insights into early glial-mediated pathogenic mechanisms that could guide targeted therapeutic strategies for TDP-43 proteinopathies.\n\nID: 42403869\nTitle: Cardiovascular Biomarkers as a Primary Care Gateway to Early Alzheimer's Disease Detection: The Case for an Integrated Screening Approach.\nAbstract: Alzheimer's disease (AD) affects millions of Americans and represents one of the leading causes of disability and healthcare expenditure in the United States. The vast majority of patients are diagnosed at the symptomatic stage, when substantial neuronal loss has already occurred and the therapeutic window for disease-modifying treatment has closed. Recently approved disease-modifying therapies have created an urgent clinical need for pre-symptomatic patient identification. The cardiovascular risk factors most commonly managed in primary care -- hypertension, dyslipidemia, type 2 diabetes, atrial fibrillation, and chronic heart failure -- are among the most powerful modifiable antecedents of AD pathology, operating through systemic inflammation, cerebral small vessel disease, impaired glymphatic clearance, and tau hyperphosphorylation. The biomarkers used to monitor these conditions -- C-reactive protein, cardiac troponin, NT-proBNP, and homocysteine -- reflect active neurodegeneration risk processes already measured routinely in primary care. This clinical perspective proposes a three-stage\u00a0integrated neuro-cardiological screening protocol linking cardiovascular biomarker assessment to plasma P-tau217 blood testing for AD confirmation. This framework addresses the implementation gap identified in recent United States primary care literature and represents a practical step toward closing the AD diagnostic gap.\n\nID: 42403482\nTitle: Disrupted glymphatic function and its relationship with sleep and cognitive impairment in ME/CFS assessed via DTI-ALPS.\nAbstract: The glymphatic system is a recently discovered brain waste clearance system that is mostly active during sleep and disengaged during wakefulness. Impaired glymphatic function leads to the deposition of metabolic waste products in the brain potentially causing inflammation leading to various symptoms in ME/CFS. While the glymphatic function has been assessed in other neurodegenerative diseases using 'diffusion tensor imaging along the perivascular space' (DTI-ALPS), it has not been studied in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). This preliminary study investigates glymphatic function in 58 participants (ME/CFS\u202f=\u202f31 and healthy controls\u202f=\u202f27) using the DTI-ALPS index derived from DTI data acquired with 3\u202fT MRI. The bilateral hemispheric DTI-ALPS index was estimated to assess glymphatic function, and an asymmetry index was calculated to determine interhemispheric asymmetry in glymphatic function. We found that the global DTI-ALPS index was significantly lower in ME/CFS patients compared to healthy controls (ME/CFS: 1.44\u202f\u00b1\u202f0.086; healthy controls: 1.51\u202f\u00b1\u202f0.11, p\u202f=\u202f0.014), indicating reduced glymphatic function in ME/CFS. Examining the hemispheres separately, showed the right hemisphere DTI-ALPS index was lower in ME/CFS than healthy controls (ME/CFS\u202f=\u202f1.41\u202f\u00b1\u202f0.097; healthy controls\u202f=\u202f1.49\u202f\u00b1\u202f0.12; p\u202f=\u202f0.009) but not different on the left. Additionally, we did not find any significant difference in asymmetry index between ME/CFS and healthy controls. We observed an association between the global DTI-ALPS index and severity of 'sleep disturbance' (p\u202f=\u202f0.013, r\u202f=\u202f-0.47) and \"impaired concentration\" (p\u202f=\u202f0.026, r\u202f=\u202f-0.43). This study demonstrated impaired glymphatic function in ME/CFS which may lead to symptoms such as cognitive dysfunction and sleep disturbance experienced by ME/CFS.\n\nID: 42401926\nTitle: Targeting the cGAS-STING pathway alleviates neuroinflammation and cognitive impairment induced by chronic infection of Toxoplasma gondii.\nAbstract: Chronic infection of Toxoplasma gondii has been established as a contributor to cognitive impairment via inducing sustained neuroinflammation and synaptic damage. However, the underlying mechanisms remain poorly understood. As a key regulator of both neuroinflammation and cellular senescence, Cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is implicated in pathogenesis induced by T. gondii infection. Here, we found that cGAS-STING pathway was activated in the cerebral cortex of mouse chronically infected with T. gondii, as indicated by the elevated protein levels of cGAS and STING, and increased phosphorylation of TBK1 and IRF3. Pharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage. Moreover, chronic T. gondii infection was shown to trigger senescence characterized by increased expression of senescence markers P16, P21 and P53, and senescence-associated secretory phenotypes (SASPs), including Il-1\u03b2, Il-6, Tnf-\u03b1, Cxcl1, Cxcl10 and Mmp9. In addition, elevated expression of \u03b2-galactosidase, a senescence marker, was predominantly observed in neurons compared to microglia and astrocytes, indicating a primary role for neurons in infection-associated senescence. Notably, these phenotypes of senescence were rescued by inhibition of the cGAS-STING pathway. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases.\n\nID: 42393750\nTitle: Microglial checkpoint collapse in Alzheimer's disease: a tri-axial framework for biomarker-informed neuroimmune therapy.\nAbstract: Anti-amyloid antibodies have validated amyloid-\u03b2 (A\u03b2) as a disease-relevant target in Alzheimer's disease (AD), but their modest clinical effect, efficacy largely restricted to early disease, and amyloid-related imaging abnormalities (ARIA) indicate that A\u03b2 removal alone does not resolve the glial, lipid, and inflammatory programmes that sustain neurodegeneration. Microglia sit at the centre of this therapeutic gap. Single-nucleus and spatial profiling has resolved several AD-associated microglial states, yet state labels remain descriptive and do not explain why adaptive engagement becomes maladaptive. We frame AD-relevant microglial dysfunction as checkpoint collapse: progressive failure of regulatory nodes that coordinate lipid sensing, lysosomal competence, neuronal restraint, and inflammatory threshold control. The central nodes are TREM2-mediated lipid and apolipoprotein sensing, progranulin-associated lysosomal regulation, CX3CR1-dependent neuron-microglia restraint, and CD33/Siglec-3 inhibitory tone. When these controls destabilise, downstream pathology can be organised around three coupled effector axes: a lipid axis centred on APOE-biased cholesterol trafficking, ACSL1/DGAT2-driven lipid-droplet accumulation, and impaired lysosomal flux; an iron/ferroptosis axis involving labile iron, phospholipid peroxidation, and insufficient GPX4/FSP1 defences; and an inflammation/complement axis linking NLRP3 activation, type-I interferon signalling, and C1q/C3-dependent synaptic engulfment to tau pathology and synapse loss. White-matter injury, astrocyte-microglia crosstalk, and cGAS-STING-linked senescence are integrated as cross-axis amplifiers. This framework is proposed as a hypothesis-generating scaffold for biomarker-informed translational studies, rather than as a validated clinical stratification system. It may help organise stage-aware therapeutic hypotheses, including regulatory-node preservation in early disease, lipid-handling restoration and ferroptosis control at intermediate stages, and complement- or senescence-directed modulation in later disease. Current glial, iron, inflammatory, and imaging biomarkers remain insufficiently specific to assign individual patients reliably to discrete pathological axes in clinical practice.\n\nID: 42383352\nTitle: Therapeutic targeting of the cGAS-STING pathway in human disease.\nAbstract: The cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is a central regulator of innate immunity that links cytosolic DNA sensing to type I IFN and inflammatory responses. While initially viewed as a uniformly beneficial antiviral and antitumor signaling axis, emerging evidence reveals that cGAS-STING functions as a context-dependent immune rheostat whose impact is dictated by signal magnitude, timing, cellular origin, subcellular localization of signaling components, and tissue context. These parameters explain why pathway activation can promote tumor rejection, vaccine efficacy, and host defense in some settings yet drive immune suppression, metastasis, neuroinflammation, or autoinflammatory disease in others. In this Review, we synthesize mechanistic and clinical insights across agonist and antagonist strategies targeting the cGAS-STING pathway in cancer, infectious disease, neurodegeneration, and interferonopathies. We highlight why first-generation STING agonists have underperformed clinically and how next-generation delivery systems and cGAS-directed approaches may overcome these limitations. We propose a disease-centric framework that integrates spatial delivery, dosing architecture, and pharmacodynamic biomarker discovery to enable rational modulation of cGAS-STING, repositioning the pathway as a tunable immunologic control node for precision therapy rather than a binary on/off switch.\n\nID: 42378309\nTitle: A single Citrobacter rodentium infection in Pink1 knockout and wild-type mice leads to regional blood-brain-barrier perturbation and limited microglial activation without dopamine neuron axon terminal loss.\nAbstract: A growing body of research suggests a link between immune system activation and the development of Parkinson's disease (PD). Previous work showed that repeated gastrointestinal infection with Citrobacter rodentium can induce PD-like motor dysfunction in Pink1 knockout (KO) mice, along with immune cell infiltration into the brain. To better understand mechanisms underlying immune-mediated brain attack in this model, we tested whether mild infections are sufficient to increase blood-brain barrier (BBB) permeability and trigger brain inflammation. Pink1 wild-type (WT) and KO mice were infected with C. rodentium, and gadolinium-enhanced magnetic resonance imaging (MRI) was performed at days 13 and 26 post-infection to assess BBB integrity. Quantitative MRI analysis revealed increased BBB permeability at day 26 in both WT and KO mice, particularly in the striatum, dentate gyrus, somatosensory cortex, and thalamus. Notably, this permeability was not associated with changes in tight junction protein expression or dopamine system markers in the striatum at either time point. However, persistent microglial activation was observed at day 26 post-infection, along with elevated levels of inflammatory mediators such as eotaxin, IFN-\u03b3, CXCL9, IL-17, and MIP-2 in the striatum. Additionally, serum levels of IL-17 and CXCL1 were increased in infected Pink1 KO mice. Flow cytometry revealed neutrophil infiltration in the brain at day 26 post-infection. Finally, a bulk RNA-seq transcriptome analysis revealed that gene sets related to synaptic function were particularly influenced by the infection and that inflammation-related genes were upregulated by the infection in the Pink1 KO mice. These findings support the hypothesis that even mild gastrointestinal infections can increase BBB permeability, disrupt brain homeostasis, and promote chronic neuroinflammation. In genetically susceptible individuals, such as those with Pink1 deficiency, this may represent a first hit that contributes to subsequent induction of PD pathology with aging.\n\nID: 42376186\nTitle: Early brain-penetrant immunotherapy reverses interferon signature and improves motor outcome in a case of ADAR1-related Aicardi-Gouti\u00e8res syndrome.\nAbstract: Aicardi-Gouti\u00e8res syndrome (AGS) is a genetic interferonopathy resulting from defects in nucleic acid metabolism and subsequent enhanced type I interferon signalling. We report how an expedited genomic diagnosis in conjunction with natural history data can enable a long-term brain-penetrant anti-inflammatory regimen to optimise neurodevelopmental outcomes in genetic autoinflammatory brain disorders. Expedited genomic testing identified compound heterozygous ADAR1 mutations. Published natural history data from 33 patients with biallelic ADAR1 mutations reported severe disability (GMFCS V) or death in 79%. To reduce neuroinflammation, we commenced a long-term pulsed oral dexamethasone protocol (20\u2009mg/m2 for 3\u2009days every 3\u2009weeks) from the age of 11\u2009months, plus ruxolitinib, a Janus Kinase (JAK) inhibitor (5\u2009mg per day). At the age of 24\u2009months, the patient was crawling and walking a few steps unaided, with a GMFCS level of II. Single-cell RNA sequencing of 41\u2009164 leukocytes, taken before and after 3\u2009months of treatment and compared to three age matched male controls, showed a reversal of upregulated pan-cellular interferon pathways, with most differentially expressed genes observed in monocytes. On treatment, there was statistically significant downregulation of key autoinflammatory genes, including nucleic acid sensing (CGAS, IFIH1, SAMHD1), interferon-stimulated genes (ISG15 and IFIF44L) and signalling (JAK1). Given the dual immune therapy, it was not possible to define whether the biological effect was related to dexamethasone or JAK inhibitor, or both. Compared with natural history data, our data suggest that early diagnosis, and the use of early brain-penetrant immune suppressants (dexamethasone), may improve outcomes in ADAR1 AGS.\n\nID: 42364866\nTitle: Co-exposure to environmental lead and hypertension exacerbates anxiety and depression via mtDNA-mediated cGAS phase separation.\nAbstract: Environmental exposure to heavy metals such as lead (Pb) and the growing prevalence of hypertension (HTN) represent significant and often coexisting global health threats. However, the combined neurotoxic effects of Pb and HTN, particularly in terms of mood disorders such as anxiety and depression, remain poorly understood. Herein, using a combined exposure model, we found co-exposure to Pb and HTN markedly aggravates anxiety- and depression-like behaviors in mice compared with Pb and HTN exposure alone. The prefrontal cortex was identified as the most vulnerable brain region, with astrocytes as the most susceptible cell type to senescence. Notably, treatment with dasatinib and quercetin, a senolytic regimen that selectively eliminates senescent cells, significantly alleviated the behavioral deficits induced by Pb and HTN co-exposure. Further investigation revealed Pb and angiotensin II (AngII) co-exposure promoted phase separation of cyclic GMP-AMP synthase (cGAS), a key DNA sensor. Pharmacological disruption of biomolecular condensates with 1,6-hexanediol (1,6-HD) partially rescued astrocyte senescence induced by Pb and AngII co-exposure. Inhibition of mitochondrial DNA (mtDNA) replication with ethidium bromide (EtBr) markedly reduced cytosolic mtDNA accumulation caused by co-exposure, suppressed cGAS phase separation, and downregulated the expression of senescence-associated proteins including P16, P211, \u03b3H2AX, and SASP. These findings uncover a previously unrecognized role of mtDNA-dependent cGAS phase separation in driving astrocyte senescence and environment-related neuropsychiatric dysfunction, and highlight cGAS phase separation as a promising therapeutic target for preventing anxiety and depression in individuals simultaneously exposed to Pb and HTN.\n\nID: 42478605\nTitle: Early Hypo-Osmolar Stress Regulates Astrocyte Reactivity After Brain Injury: \"New Insights Into Glial Response to Edema\".\nAbstract: Astrocytes are among the first cellular responders to central nervous system injury, yet the mechanisms governing their earliest responses remain incompletely understood. Here, we investigated astrocyte dynamics during the first hours after focal cortical injury induced by cortical devascularization in rats. We observed a rapid and spatially restricted increase in glial fibrillary acidic protein (GFAP) and aquaporin-4 (AQP4) immunoreactivity surrounding the ischemic core as early as 1.5-3.5\u2009h post-lesion, in association with blood-brain barrier disruption and edema-related changes. Within the injury core, astrocytes displayed differential GFAP detection by monoclonal and polyclonal antibodies, together with the appearance of lower-molecular-weight GFAP fragments both in\u00a0vivo and after oxygen-glucose deprivation in\u00a0vitro, suggesting GFAP cleavage in severely damaged astrocytes. At the chromatin level, astrocytes proximal to the lesion exhibited reduced histone H3 acetylation, particularly histone 3 acetylation at lysine 9 (H3K9ac), a phenomenon recapitulated in cultured astrocytes exposed to hypo-osmolar stress. This reduction was transient, reversible upon recovery, and prevented by histone deacetylase (HDAC) inhibition. Functionally, hypo-osmolar stress conditioned astrocyte responses to subsequent stimuli, attenuating nuclear factor kappa B (NF-\u03baB) activation and complement 3 (C3) induction after lipopolysaccharide exposure while enhancing proliferative capacity during recovery. Together, these findings identify edema-associated osmotic stress as an early regulator of astrocyte epigenetic state and functional plasticity, suggesting that astrocytes exposed to edema are primed to adopt distinct responses that may contribute to tissue repair and scar formation following brain injury.\n\nID: 42468026\nTitle: Double-Negative Neuromyelitis Optica Spectrum Disorder: A Systematic Review and Meta-Analysis.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is a severe condition usually associated with aquaporin-4 (AQP4) antibodies. A clinical presentation suggestive of NMOSD can also be associated with myelin oligodendrocyte glycoprotein (MOG) antibodies (MOGAD). NMOSD can be diagnosed in the absence of autoantibodies (double-negative NMOSD [DN-NMOSD]), but this subgroup has been poorly investigated. We conducted a systematic review and meta-analysis to define the clinical spectrum, prognosis, and treatment response in DN-NMOSD vs AQP4-NMOSD/MOGAD. We searched on PubMed, Scopus, Embase, Google Scholar, Cochrane Library, and ClinicalTrials.gov databases of studies on patients fulfilling inclusion criteria. Patient characteristics, outcome measures, and treatment regimens were extracted. We included 41 of 1,027 articles screened and analyzed 671 patients with DN-NMOSD (median age 38.6 years [range IQR: 32.5-42.85]; female-to-male ratio 1.5:1; median follow-up 44.4 months [range 1-600]), 73.6% of which relapsed. In the meta-analysis, mean annualized relapse rate (ARR) was higher, albeit not significantly, in DN-NMOSD (1.08; 95% CI 0.73-1.43) vs AQP4-NMOSD (0.84; 95% CI 0.45-1.23) and MOGAD (0.61; 95% CI 0.39-0.83, p = 0.08). Administration of maintenance immunosuppression in DN-NMOSD led to a significant ARR reduction (pooled rate ratio 0.19, 95% CI 0.07-0.49; p = 0.001), with high heterogeneity (I2 = 90%, p < 0.0001). In meta-regression, no covariates were associated with ARR reduction, including the administration of specific drugs (rituximab, p = 0.288; azathioprine, p = 0.291; mycophenolate, p = 0.918). The pooled mean difference in pre\u2011 and post\u2011maintenance treatment Expanded Disability Status Scale values indicated a significant change in disability in MOGAD (-0.93, 95% CI -1.67 to -0.19, p = 0.02) but not in AQP4-NMOSD (-0.62, 95% CI -1.85 to 0.61, p = 0.27) or DN-NMOSD (-0.52 (95% CI -1.30 to 0.25, p = 0.16). DN-NMOSD is a heterogenous, severe and highly relapsing disease, where attacks lead to irreversible dysfunction. The administration of maintenance immunotherapy reduces the relapse risk and should be considered early to prevent further disability.\n\nID: 42458195\nTitle: Comparative Evaluation of Rituximab Versus Approved Therapies in Aquaporin-4-IgG-Positive Neuromyelitis Optica Spectrum Disorder: A Systematic Review and Network Meta-analysis.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is a rare antibody-mediated neuro-autoimmune disease. Monoclonal antibodies targeting B\u00a0cell antigens CD19 and CD20, the interleukin-6 receptor, or the complement cascade are used as preventive therapies to reduce relapse rates. We conducted a network meta-analysis (NMA) to compare the effect of rituximab on time to first relapse with ravulizumab, eculizumab, inebilizumab, and satralizumab in patients with NMOSD who are aquaporin-4 (AQP4)-IgG-positive. A systematic search was conducted in PubMed, Scopus, CINAHL, EMBASE, Web of Science, the Cochrane Library, and gray literature sources up to October 31, 2024, and updated on November 1, 2025, following PRISMA guidelines. A network meta-analysis of randomized and open-label trials was conducted to compare time to first relapse between rituximab and other monoclonal antibody therapies. From 6337 records, 3825 duplicates were removed; 2512 were screened, 2327 excluded, leaving eight trials. The prior treatment, relapse history, and definitions and adjudication of relapse varied across studies. Rituximab showed higher hazard ratio (HR) point estimates for time to first relapse compared with ravulizumab with or without immunosuppressive therapies (IST) (HR 5.00, 95%\u00a0CI 0.25, 101.01) and eculizumab\u2009\u00b1\u2009IST (HR 1.17, 95%\u00a0CI 0.12, 10.89), but were lower compared with satralizumab\u2009\u00b1\u2009IST (HR 0.29, 95%\u00a0CI 0.04, 2.23). In patients not receiving IST, rituximab showed numerically higher HR compared with ravulizumab (HR 3.33, 95%\u00a0CI 0.13, 83.16) and eculizumab (HR 1.59, 95%\u00a0CI 0.05, 50.17), but lower point estimates compared with inebilizumab (HR 0.31, 95%\u00a0CI 0.04, 2.31) and satralizumab (HR 0.27, 95%\u00a0CI 0.03, 2.21). This NMA showed hazard ratio point estimates favoring eculizumab and ravulizumab over rituximab. However, wide, overlapping confidence intervals and between-study heterogeneity indicate substantial uncertainty. Head-to-head trials or registry-based studies are needed to determine the most effective treatment for AQP4-IgG-positive NMOSD.\n\nID: 42457661\nTitle: Fatigue after COVID-19 infection is associated with peripheral immunometabolic alterations affecting neuroimmune responses in the hippocampus.\nAbstract: Fatigue is a common and disabling symptom reported following SARS-CoV-2 infection, yet the underlying biological mechanisms remain poorly understood. In this study, we investigated whether fatigue severity in individuals previously infected with SARS-CoV-2 is associated with immune and metabolic alterations in serum and whether these peripheral changes can influence hippocampal cell function in vitro. Serum cytokines, kynurenine pathway, and tryptophan-derived and monoamine-related metabolites were measured in a total of 38 individuals with past COVID-19 infection. Human hippocampal progenitor cells were exposed to 1% patient serum during proliferation and differentiation, with readouts including cytokine release, metabolite production, and markers of neurogenesis (doublecortin, DCX) and astrocytic reactivity (glial fibrillary acidic protein, GFAP; aquaporin-4, AQP4). Results show that fatigue severity correlates with lower serum levels of interleukin-8 (IL-8) and with lower levels of metabolites of the kynurenine pathway and tryptophan-derived and monoamine-related metabolites, including kynurenine (KYN) and quinolinic acid (QUIN), and 5-hydroxyindoleacetic acid (5HIAA). Exposure of hippocampal cells to serum from individuals with higher fatigue was associated with increased endogenous production of interleukin-13 (IL-13) and the kynurenine metabolite anthranilic acid (ANA) in the cell supernatant, as well as with increased neurogenesis (increased DCX expression) and enhanced astrocytic reactivity (increased GFAP expression). Notably, serum IL-8 level was inversely correlated with both cellular outcomes. Likewise, serum 5-HIAA levels were negatively correlated with IL-13 release, with mediation analysis indicating that 5-HIAA significantly mediated the association between fatigue severity and IL-13 production (71% explained). Overall, our results suggest that fatigue after COVID-19 infection is associated with neuroimmune and metabolic changes in hippocampal cells, involving peripheral serotonin metabolism (5-HIAA) and cytokine signalling (IL-13).\n\nID: 42450349\nTitle: Ionic Homeostasis Failure in Major Depressive Disorder: Ion Channel Mechanisms, Excitation-Inhibition Imbalance, and Precision Therapeutics.\nAbstract: Major depressive disorder (MDD) remains a leading cause of disability; however, monoaminergic models do not fully explain delayed treatment onset, incomplete remission, or rapid responses to glutamatergic interventions. In this study, we proposed a system-level ionic homeostasis framework for MDD. In this model, genetic susceptibility, chronic stress, metabolic burden, and neuroinflammation converge in neuronal and glial ion-channel systems, disrupting calcium, potassium, chloride, and purinergic homeostasis. These disturbances alter intrinsic excitability, synaptic integration, inhibitory tone, glial buffering, and neuron-glia signaling, thereby promoting excitation-inhibition imbalance, impaired plasticity, and corticolimbic network instability. We reviewed the evidence implicating the CACNA1C/Cav1.2, TREK-1, KCNQ, NKCC1/KCC2, HCN, transient receptor potential/acid-sensing ion channels, and glial mediators, including P2X7R, Kir4.1, and AQP4. We also discuss how ketamine-related mechanisms, chloride-restoring strategies, anti-inflammatory ion channel targeting, neuromodulation, EEG biomarkers, and AI/multiomics approaches support mechanism-informed precision therapeutics. MDD could be conceptualized as a distributed failure of ionic homeostasis that links neuroinflammation, E/I imbalance, network instability, and impaired adaptive plasticity.\n\nID: 42440328\nTitle: Interleukin 6 Receptor Blockade for Relapse Prevention in Myelin Oligodendrocyte Glycoprotein Antibody-Associated Disease.\nAbstract: Myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) lacks proven relapse-preventive therapies. While clinical trials are ongoing, safety data may be limited and approved drugs are costly. Studies of interleukin 6 receptor blocker (IL-6RB) in MOGAD are limited by small numbers and no comparative studies, contributing to low use. To evaluate the impact of IL-6RB therapy on relapse rates in MOGAD and compare relapse frequency with intravenous immunoglobulin (IVIG). This international, multicenter, retrospective cohort study (January 1, 2015, through December 31, 2025) included a historical IVIG-treated cohort of varying doses. The study took place across sites in North and South America (US, Canada, Mexico, Argentina, Brazil, Chile, Colombia, and Peru). Patients with MOGAD (n\u2009=\u2009116, no excluded patients) who received at least 1 dose of an IL-6RB were included. These data were analyzed in January 2026. Tocilizumab or satralizumab. Annualized relapse rate (ARR) during IL-6RB therapy, time to next relapse after treatment initiation, and adverse events. Outcomes were compared with the IVIG cohort using inverse probability of treatment weighting (IPTW) adjusted for age, sex, prior ARR, and concomitant therapies. A total of 116 patients with MOGAD (89% relapsing) receiving IL-6RB (tocilizumab, 104 [90%] and satralizumab, 12 [10%]) were included; overall, 60.3% were female, 39.7% were male, and 18% were younger than 18 years. The median (IQR) IL-6RB treatment follow-up was 1.4 (0.7-2.5) years and 23 relapses occurred during 241.8 person-years of IL-6RB therapy. The ARR decreased from 0.64 (95% CI, 0.58-0.70) for relapsing MOGAD before IL-6RB to 0.09 (95% CI, 0.06-0.14) during IL-6RB treatment (incidence rate ratio, 0.08; 95% CI, 0.04-0.16). Adverse events occurred in 58 patients (50%), most commonly mild infections, although 10 (9%) had severe infections. In the IVIG cohort (n\u2009=\u200959), 30 relapses occurred over 133.8 person-years (ARR, 0.22; 95% CI, 0.15-0.32). After IPTW, IL-6RB was associated with a lower hazard ratio (HR) than the group who underwent IVIG therapy less than 1 g/kg every 4 weeks (HR, 4.5; 95% CI, 2.0-9.8), with no significant difference vs the group who underwent IVIG 1 g/kg or more every 4 weeks (HR, 2.0; 95% CI, 0.8-4.5). In this multicenter observational cohort, IL-6RB use in MOGAD was associated with low relapse rates and a favorable safety profile, though severe infections occurred occasionally. Relapse rates were lower than the group who underwent IVIG less than 1 g/kg every 4 weeks but not significantly different from the group who underwent IVIG 1 g/kg or more every 4 weeks. This supports IL-6RB as a potential relapse-prevention therapy in MOGAD; the wide availability and relative affordability of tocilizumab may enable broad global use.\n\nID: 42435823\nTitle: Response to the Letter to the Editor regarding our article \"Role of AQP4-mediated glymphatic system dysfunction in postoperative neuroinflammation and cognitive dysfunction\".\nAbstract: \n\nID: 42419635\nTitle: The Glymphatic system: A key mechanism linking sleep to brain health and diseases.\nAbstract: Sleep is increasingly recognized as a fundamental regulator of brain homeostasis, yet the mechanisms linking sleep to neurological health have only recently begun to emerge. The glymphatic system, a brain-wide perivascular transport network, has provided a mechanistic framework connecting sleep physiology with brain health and disease. Accumulating evidence indicates that glymphatic activity is markedly enhanced during sleep through coordinated regulation of vasomotion, norepinephrine oscillations, aquaporin-4 polarization, extracellular space expansion, respiration, and meningeal lymphatic drainage. Conversely, chronic sleep disruption impairs glymphatic transport, promotes the accumulation of neurotoxic metabolites, and contributes to neuroinflammation, thereby accelerating the progression of diverse neurological disorders. In this review, we integrate recent advances in glymphatic biology from structural organization and transport mechanisms to sleep-dependent regulation and emerging neuroimaging approaches. We critically evaluate current evidence supporting glymphatic dysfunction in neurodegenerative diseases, traumatic brain injury, cerebrovascular disorders, psychiatric disorders, brain tumors, and ocular diseases, highlighting sleep-related impairment as a common mechanistic denominator. Particular emphasis is placed on the translational potential and limitations of non-invasive imaging biomarkers, including DTI-ALPS, dynamic contrast-enhanced MRI, diffusion MRI, PET, and emerging multimodal techniques. We also discuss major controversies surrounding glymphatic physiology, including the relative contributions of bulk flow and diffusion, species-specific differences, and the challenges of validating human imaging biomarkers. Finally, we propose a conceptual sleep-glymphatic-disease axis that integrates current mechanistic knowledge with clinical translation. Understanding how sleep regulates glymphatic function may provide new opportunities for disease prevention, biomarker development, and therapeutic intervention across a broad spectrum of brain disorders.\n\nID: 42399450\nTitle: miR-6836-5p Drives Astrocyte Pro-survival Signaling Through DLG2-Hippo-YAP Pathway Under AQP4-IgG\u2009+\u2009ve NMOSD Stress.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune astrocytopathy mainly driven by serum antibodies against aquaporin-4 (AQP4-IgG). While antibody-mediated injury to astrocytes is well documented, the intrinsic cellular responses that influence astrocyte survival under such stress remain poorly understood. In this study, differentiated U87MG astrocytoma cells served as an in vitro model to examine the effects of AQP4-IgG\u2009+\u2009ve NMOSD patient sera on microRNA-mediated signaling. Small RNA sequencing and qRT-PCR revealed that hsa-miR-6836-5p was the most strongly induced miRNA within 4\u00a0h of exposure, consistent with the peak downregulation of AQP4. Functional enrichment and target prediction identified the Hippo-YAP signaling pathway, with Discs Large Homolog 2 (DLG2) as a key downstream target. AQP4-IgG\u2009+\u2009ve sera reduced DLG2 expression, decreased LATS1 and YAP phosphorylation, and upregulated YAP-dependent pro-survival genes (CTGF, CYR61, GLI2), along with an increased BCL-2/BAX ratio, initiating an acute pro-survival response. Inhibition of miR-6836-5p restored DLG2 levels, reactivated the Hippo signaling pathway, and reinstated apoptotic signaling. These findings unveil a novel miR-6836-5p-DLG2-Hippo-YAP axis that promotes pro-survival signaling in astrocytes under autoimmune stress, indicating miR-6836-5p as a potential molecular regulator of astrocyte fate in NMOSD.\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: 42391599\nTitle: Factors Associated With Disability Improvement and Worsening Independent of Attacks in Patients With AQP4-IgG+ NMOSD and MOGAD: A Multicenter Cohort Study.\nAbstract: Disability trajectories in aquaporin-4 immunoglobulin G-seropositive neuromyelitis optica spectrum disorder (AQP4-IgG+ NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) are primarily driven by attack-related damage. Confirmed disability worsening (CDW) independent of attacks has been described but occurs infrequently in AQP4-IgG+ NMOSD and MOGAD. Confirmed disability improvement (CDI) has not been evaluated in large cohorts. We determined the frequency of CDI and CDW independent of attacks and identified clinical factors associated with these outcomes in AQP4-IgG+ NMOSD and MOGAD. This retrospective, multicenter cohort study analyzed data from the German Neuromyelitis Optica Study Group (NEMOS) registry. Adult patients with AQP4-IgG+ NMOSD or MOGAD and longitudinal Expanded Disability Status Scale (EDSS) assessments were included. EDSS episodes were defined as periods with \u22653 EDSS assessments without attacks, obtained \u226590 days after attack. CDW and CDI were defined as sustained EDSS increase or decrease (\u22651.5 for baseline EDSS 0; \u22651.0 for EDSS 1.0-5.5; \u22650.5 for EDSS \u22656.0) confirmed after at least 6 months. The primary outcomes were annualized CDI and CDW rates. Risk factors were assessed using multivariable Anderson-Gill regression models. A total of 338 EDSS episodes of 307 patients (n: 202/105, median age at EDSS change: 56/41 years, 88/49% female, both p < 0.001; AQP4-IgG+ NMOSD/MOGAD) were included. Adjusted annualized CDI and CDW rates did not differ between AQP4-IgG+ NMOSD (CDI: 0.083, 95% CI 0.029-0.233; CDW: 0.025, 95% CI 0.007-0.092) and MOGAD (CDI: 0.057, 95% CI 0.012-0.277; CDW: 0.036, 95% CI 0.002-0.513). In AQP4-IgG+ NMOSD, a lower number of prior attacks was associated with higher CDI rates (hazard ratio [HR] 0.89, 95% CI 0.82-0.97). Younger age was associated with increased CDI rates in both AQP4-IgG+ NMOSD and MOGAD (HR 0.96, 95% CI 0.94-0.99, for both). CDI and CDW independent of attacks, although rare, occur in AQP4-IgG+ NMOSD and MOGAD. The association between fewer prior attacks and higher CDI rates in AQP4-IgG+ NMOSD underscores the importance of early attack prevention. Limitations include the retrospective design, and the limited number of CDI and CDW events.\n\nID: 42387224\nTitle: AQP4-IgG Dynamics and Exploratory Assessment of SERA-3 in Neuromyelitis Optica Spectrum Disorder Treated with Satralizumab.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune condition driven by aquaporin-4 immunoglobulin G (AQP4-IgG). The current treatment paradigm focuses on mitigating clinical relapses and disability accumulation, leaving the underlying serological activity unaddressed. This study evaluated the capacity of satralizumab to achieve a comprehensive remission, as defined by the Serological, Relapse, and Accumulated-disability Remission (SERA-3) target. In this multicenter, real-world cohort study, patients with NMOSD from three tertiary centers in China initiating satralizumab were enrolled. AQP4-IgG levels were measured at baseline, 6, and 12\u00a0months. Clinical efficacy [annualized relapse rate (ARR), Expanded Disability Status Scale (EDSS)] and safety were evaluated. Heterogeneity in antibody response was analyzed, and baseline characteristics potentially associated with titer reduction were explored. Of the 19 patients who were AQP4-IgG seropositive at baseline, 7 (36.84%) met the strict definition of SERA-3 Complete. Of these, 4 patients achieved seroconversion at month 6 and remained seronegative through month 12, whereas 3 first achieved seroconversion at month 12. An additional 5 (26.32%) showed a reduction in AQP4-IgG titers. Satralizumab treatment was associated with marked clinical benefit. Among 33 patients included in the clinical efficacy analysis, 27 (81.82%) remained relapse-free during follow-up, median ARR decreased from 0.92 (IQR 0.56-1.59) to 0 (IQR 0-0), and EDSS scores remained stable in most patients. Exploratory analyses suggested that patients achieving serological response were older at disease onset (57.42\u2009\u00b1\u200917.82 versus 42\u2009\u00b1\u200914.24\u00a0years, p\u2009=\u20090.039) and had experienced fewer pre-treatment relapses (median 2 versus 5, p\u2009=\u20090.049). Satralizumab was generally well tolerated, including in older patients. Our findings support SERA-3 as a potential treatment framework for NMOSD. Satralizumab was associated with attainment of serological, relapse, and disability remission in a substantial proportion of patients, supporting further prospective evaluation of SERA-3 as a hypothesis-generating outcome framework.\n\nID: 42382323\nTitle: Role of AQP4 in ameliorating heat stress-induced cellular injury in a cell line model through active heat acclimation.\nAbstract: Heat stress (HS) can progress to heat stroke, a life-threatening condition. Aquaporin-4 (AQP4) has been implicated in HS-induced brain injury, but its role in heat acclimation (HA)-mediated protection remains unclear. This study investigated whether HA ameliorates HS-induced brain damage through AQP4. 9L/lacZ cells were randomly assigned to four groups: Control (37\u202f\u00b0C, 5% CO\u2082), HA (39\u202f\u00b0C, 5% CO\u2082, 2\u202fh/day for 6\u202fdays), HS (43\u202f\u00b0C, 5% CO\u2082, 2\u202fh), and HA+HS (HA pretreatment followed by HS). In addition, cells in the Control and HS groups were treated with the selective AQP4 inhibitor TGN-020 (0.1\u202f\u03bcmol/mL, 2\u202fh before HS). The expression of HSP70, HSP90, and AQP4 was measured by western blotting; AQP4 mRNA levels were assessed by RT-PCR. Cell proliferation viability was evaluated by CCK-8 assay, and apoptosis was detected by flow cytometry. Notably, AQP4 expression (RT-PCR and Western blot) was lower in the HA+HS group than in the HS group. Flow cytometry revealed that both HA+HS and TGN-020 treatment reduced apoptosis compared with HS alone. These findings indicate that HA attenuates HS-induced injury by downregulating AQP4 expression, and that AQP4 inhibition mimics this protective effect. AQP4 represents a potential therapeutic target for heat stroke.\n\nID: 42374283\nTitle: Switching from complement inhibitors in AQP4-IgG-positive NMOSD: clinical characteristics, an operational \"cluster phase\" and potential strategies to prevent therapeutic gaps.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) can cause severe neurological disability after a single relapse. Although relapse rates have markedly decreased with the emergence of targeted biologics, treatment switches are increasingly encountered due to long-term treatment considerations and adverse events. However, safe switching strategies, especially within 12 months after a relapse, which we defined operationally as the \"cluster phase\", have not been established. We investigated relapse risk and potential preventive strategies when switching from complement inhibitors in AQP4-IgG-positive NMOSD. We retrospectively reviewed patients with AQP4-IgG-positive NMOSD treated at St. Marianna University School of Medicine who underwent at least one biologic switch. Clinical records were assessed for patient characteristics, treatment history, timing of switching, and relapse occurrence. Particular attention was given to switching from complement inhibitors during the cluster phase. Among 14 patients who switched biologics, 5 switched from complement inhibitors, 4 switched between complement inhibitors, 2 between B-cell-depleting therapies, and 3 from IL-6 receptor inhibitors. Six of the 14 switches occurred during the cluster phase, including 3 from complement inhibitors (all to B-cell-depleting agents). One of the two patients switched without bridging therapy during the cluster phase experienced optic neuritis relapse, while no relapses occurred in the other 13 switching cases. This observation suggests a possible vulnerability during the cluster phase, although definitive conclusions cannot be drawn due to the small sample size. Switching from complement inhibitors during the cluster phase may be associated with an increased susceptibility to relapse. Bridging strategies, such as plasma exchange or temporary biologic overlap, may help reduce the likelihood of therapeutic gaps, but these findings remain hypothesis-generating. Clinicians should proactively discuss future switching scenarios and develop long-term treatment plans with patients.\n\nID: 42369157\nTitle: Ravulizumab for relapse prevention in AQP4-IgG-positive neuromyelitis optica spectrum disorder: a 2-year follow-up case report.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune disease of the central nervous system, distinct from multiple sclerosis, characterized by severe inflammatory attacks targeting the optic nerves, spinal cord, and brainstem. Treatment has evolved from broad immunosuppressants to targeted biologics, such as complement inhibitors (ravulizumab/eculizumab), supported by strong evidence, including the CHAMPION-NMOSD trial for ravulizumab in AQP4-Ab+ve NMOSD patients. This case highlights the importance of prompt diagnosis and innovative treatment approaches in the management of NMOSD. A 20-year-old woman presented with acute brainstem dysfunction (dysarthria, diplopia) and a 1-month history of area postrema syndrome (APS), progressing to dysphagia and dyspnea requiring ICU admission. Diagnostic workup revealed AQP4-IgG+ NMOSD with characteristic lesions in the area postrema, pons, and cervical cord (C1-C3). The patient achieved complete clinical recovery with ravulizumab, with near-complete radiological resolution at 3 months and clinical and radiological stability through ~24 months of follow-up, highlighting the efficacy of post-acute initiation of complement inhibition in severe NMOSD. This case demonstrates the diagnostic and therapeutic challenges of AQP4-IgG+ NMOSD in a young patient presenting with area postrema syndrome. The patient remained clinically stable and free of new MRI activity through ~24 months of follow-up on ravulizumab.\n\nID: 42335445\nTitle: Immunity Gone Viral: Subacute Cognitive Decline With Multifocal Brain Lesions in Neuromyelitis Optica Spectrum Disorder.\nAbstract: Subacute cognitive decline and imbalance in aquaporin-4-antibody-seropositive neuromyelitis optica spectrum disorder (AQP4+NMOSD) treated with mycophenolate has a broad differential diagnosis, including cerebral involvement of AQP4+NMOSD, infections, or other complications of immunosuppression. In this article, we highlight the diagnostic and treatment approach in a patient with AQP4+NMOSD who developed multifocal brain lesions.\n\nID: 42321927\nTitle: Unmet needs in the care of patients with neuromyelitis optica spectrum disorder and myelin oligodendrocyte glycoprotein antibody associated disease: insights from Germany.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) are rare autoimmune disorders. Their true prevalence in Germany is unknown and can only be estimated from heterogeneous international data. Assuming 1-3 cases per 100,000 people for each disease suggests several thousand affected individuals nationwide, yet the German Neuromyelitis Optica Study Group (NEMOS) registry currently holds records of only about 1,300 patients seen in specialised centres. Numbers and care structures outside such facilities remain largely unknown. This survey aimed to assess the current state of NMOSD and MOGAD care in Germany, identify gaps, and inform future care strategies. An online questionnaire aimed at neurologists and neuropaediatricians was distributed via NEMOS, the German Neurological Society (DGN), the Professional Association of German Neurologists (BVDN), and the German Network for Research on Autoimmune Encephalitis (GENERATE) from March to May 2025. Questions addressed care structures, diagnostics, coding, treatment, guideline use, and practitioners' needs. A total of 104 physicians from all German federal states participated. Half worked in university hospitals, the remainder in other clinics and outpatient settings. Most were specialised in neuroimmunology (70.2%). Many reported an increase in patient numbers for NMOSD (55.8%) and MOGAD (77.4%). Diagnostic practices revealed significant inconsistencies: almost half of the respondents were unaware of their referral laboratory's antibody assays, and ELISA remained in use despite clear recommendations for cell-based assays. ICD-10 coding varied widely. Off-label rituximab was most frequently used for first-line therapy of AQP4-antibody-positive NMOSD (69.6%), compared to satralizumab (57.1%), ravulizumab (55.4%) and inebilizumab (50.0%). AQP4-antibody-negative NMOSD was mainly treated with rituximab (87.0%). Also in MOGAD, rituximab was frequently used (by 58.9%), yet paediatricians preferred glucocorticoids and intravenous immunoglobulins. 69.6% initiated treatment for MOGAD after the first attack. Notably, 41.8% of physicians reported untreated NMOSD and 64.6% untreated MOGAD patients. Most respondents relied on national guidelines; 43.2% expressed a need for further education and patient information. Our findings highlight substantial heterogeneity in the diagnosis and treatment of NMOSD and MOGAD in Germany with potential implications for patient outcomes. This underscores the need for harmonised procedures and targeted educational resources to improve diagnostic reliability, treatment equity, and overall quality of care.\n\nID: 42309987\nTitle: Contributions of the Alzheimer's Disease Neuroimaging Initiative to advancing AD research: a targeted review of recent publications.\nAbstract: The Alzheimer's Disease Neuroimaging Initiative (ADNI) recently celebrated its 20th anniversary, reflecting two decades of major contributions to Alzheimer's research through open data sharing and longitudinal multimodal assessments. This review synthesizes 122 high-impact studies using ADNI data or biospecimens from 2023 to mid-2025 to clarify mechanisms of Alzheimer's disease (AD) progression. Studies describe impairment of glymphatic clearance and the impact of cerebral small vessel disease, trajectories of amyloid beta and tau deposition, inflammation, metabolic disturbances, synaptic dysfunction, and neurodegeneration, leading to cognitive impairment and neuropsychiatric symptoms. Multifactorial contributions from genetic and epigenetic influences, co-pathologies and comorbidities, and mechanisms of resilience modulate disease progression. Finally, heterogeneity of clinical presentation and disease course is described in the context of multiple contributing factors, highlighting the complexity of AD. By integrating imaging, fluid biomarkers, genetics, and clinical measures, ADNI provides a comprehensive research dataset for unraveling mechanisms underlying AD progression.\n\nID: 42295768\nTitle: IL-6 Receptor Blockade as Rescue Therapy in Acute Attacks of MOGAD and AQP4+NMOSD.\nAbstract: This case series describes multicenter experience with interleukin 6 (IL-6) receptor blockers used during attacks in aquaporin 4\u2013immunoglobulin G\u2013positive neuromyelitis optica spectrum disorder (AQP4+NMOSD) and myelin oligodendrocyte glycoprotein antibody\u2013associated disease (MOGAD).\n\nID: 42295556\nTitle: Unlocking the aging brain: mTORC1 as a convergent integrator for neurodegeneration and therapeutic intervention.\nAbstract: Aging is the primary risk factor for neurodegenerative diseases, characterized by a progressive decline in cellular homeostasis. Central to this process is the mammalian target of rapamycin complex 1 (mTORC1), a convergent integrator regulator of metabolism that integrates nutrient sensing with cellular growth. While essential for development, chronic mTORC1 hyperactivity, termed mTORopathy, emerges during aging, driving a deleterious cycle of mitochondrial dysfunction, neuroinflammation, and impaired protein clearance. This pathological state promotes the accumulation of toxic proteins, such as amyloid-beta, tau, and alpha-synuclein, while simultaneously suppressing autophagy and glymphatic function. Furthermore, mTORC1 overactivation in glial cells fuels inflammaging by inducing cellular senescence and the senescence-associated secretory phenotype (SASP), which compromises blood-brain barrier integrity and synaptic plasticity. Conversely, pharmacological inhibition of mTORC1 using rapamycin or its analogs (rapalogs) has demonstrated significant neuroprotective potential. By restoring autophagic flux, rebalancing metabolic axes (AMPK/SIRT1), and suppressing chronic inflammation, these compounds can rescue synaptic function and reactivate neurogenesis. This review synthesizes current evidence regarding mTORC1 as a convergent integrator for brain aging and evaluates the clinical prospects of mTOR-targeted therapies in mitigating neurodegenerative decline.\n\nID: 42292411\nTitle: CXCL9 associates with experimental neuromyelitis optica spectrum disorder following adoptive transfer of Tfh and Th17 cells.\nAbstract: This study investigates the pathogenic contributions of aquaporin-4 (AQP4)-specific follicular helper T (Tfh) and T helper 17 (Th17) cells in neuromyelitis optica spectrum disorder (NMOSD), utilizing newly established murine models based on adoptive transfer of antigen-specific T-cell populations. AQP4-knockout mice were immunized with the AQP4-derived peptide to generate AQP4-reactive Tfh and Th17 cells. These cells were subsequently isolated and adoptively transferred into wild-type recipient mice. At disease peak-defined by consistent neurological deficits-spinal cord and brain tissues were harvested for histopathological analysis, as well as immunohistochemistry. Central nervous system immune cell infiltration was quantified via flow cytometry. Total RNA was extracted from spinal cord tissue for bulk RNA sequencing; differentially expressed genes were validated using quantitative real-time PCR. Recipient mice that received AQP4-reactive Tfh or Th17 cells developed progressive hind-limb weakness, with Th17-transferred mice exhibiting significantly more severe clinical scores. Histopathological analyses revealed robust perivascular inflammation, parenchymal immune infiltration, and focal demyelination. Immunohistochemical quantification demonstrated significantly increased the optical density of CD3, B220, GFAP, IBA1, and CXCL9, alongside markedly decreased MBP expression. Flow cytometric profiling confirmed substantial infiltration of leukocytes and activated microglia/macrophages into the central nervous system (CNS). Transcriptomic analysis identified CXCL9 as one of the most upregulated chemokines in the spinal cord; its astrocytic origin was further corroborated by confocal immunofluorescence co-localization with GFAP. Our findings establish that AQP4-specific Tfh and Th17 cells are sufficient to drive key neuropathological features of NMOSD-including microglial reactivity, leukocyte recruitment, neuroinflammation, and demyelination-in vivo. The pronounced upregulation and astrocyte-derived expression of CXCL9 suggest its involvement in orchestrating CNS inflammation and position it as a potential contributor for NMOSD.\n\nID: 42283969\nTitle: Glymphatic system impairment in neurological disorders: potential mechanisms and therapeutic targets.\nAbstract: The glymphatic system is a brain-wide metabolic clearance pathway, orchestrating the removal of neurotoxic wastes via glial-dependent perivascular networks. Mediated by polarized aquaporin-4 (AQP4) channels on astrocytic end-feet, this macroscopic system drives the convective exchange of cerebrospinal fluid (CSF) and interstitial fluid (ISF), establishing a functional coupling between the central nervous system (CNS) and the adaptive immune system. Emerging evidence highlights that glymphatic dysfunction act as both a consequence and a driver of numerous neurological disorders. Neurological pathologies, including neuroinflammation and gliovascular remodeling, compromise the structural and functional integrity of glymphatic architectures. Conversely, glymphatic dysfunction exacerbates neurotoxic wastes accumulation, accelerates disease progression, and perpetuates a pathological positive-feedback loop. Despite growing recognition of this bidirectional relationship, the precise mechanisms remain incompletely understood, and targeted therapeutic strategies are still lacking. In this review, we map the functional architecture of this pathway, from periarteriolar CSF influx to perivenous efflux, and dissect its dependence on critical modulators including sleep-wake rhythms, arterial pulsatility, and aging. Furthermore, we explore novel therapeutic interventions, ranging from AQP4-targeted pharmacological modulation to non-invasive physical approaches, and evaluate their potential to shift clinical paradigms from symptomatic management to disease modification.\n\nID: 42265653\nTitle: Bilateral immune-mediated optic neuritis following HPV vaccination in an adolescent: diagnostic challenges and a rare clinical presentation.\nAbstract: Optic neuritis (ON) is an inflammatory condition of the optic nerve that causes damage to the myelin sheath and nerve fibers, leading to acute visual impairment. While often idiopathic, ON is increasingly recognized in association with immune-mediated triggers, including post-vaccination phenomena. The proposed pathophysiology involves molecular mimicry, where vaccine-induced antigens trigger a cross-reactive immune response against myelin basic protein. Distinguishing vaccine-associated ON from primary demyelinating diseases, such as Multiple Sclerosis (MS) or Neuromyelitis Optica Spectrum Disorder (NMOSD), poses as significant diagnostic challenge, particularly in adolescents. Prompt differentiation is essential to guide clinical management and therapeutic interventions. We report a case of a previously healthy 15-year-old female who presented with a two week history of painful visual loss in the right eye, occurring seven days after quadrivalent HPV vaccination. Examination revealed marked asymmetry in visual acuity and a right-sided relative afferent pupillary defect (RAPD). Other cranial nerves (III-XII), motor, sensory, and cerebellar examinations were unremarkable; no papilledema was noted. Laboratory investigations and cerebrospinal fluid (CSF) analysis were normal, except for mild microcytic anemia. MRI of the brain, orbits, and spine demonstrated bilateral optic nerve and perineural enhancement without evidence of demyelinating plaques, confirming bilateral optic neuritis. Autoimmune serology and metabolic panels (ANA, B12, folate, zinc) were within normal limits; serum AQP4-IgG and MOG-IgG were not available at the time of writing the report. The patient received five days of intravenous methylprednisolone, resulting in substantial visual recovery at follow-up. This case demonstrates the diagnostic complexity of optic neuritis in adolescents and highlights the necessity of maintaining a high index of clinical suspicion for vaccine-associated immune-mediated events. Although bilateral optic neuritis temporally associated with vaccination is rare and the precise pathophysiological link remains a subject of ongoing debate, a thorough assessment of the clinical chronology and temporal relationship to immunization can facilitate a prompt diagnosis. Timely intervention with corticosteroids is essential to mitigate progression and prevent permanent visual sequelae. However, long-term longitudinal surveillance is mandatory to distinguish such monophasic episodes from the initial manifestation of a chronic demyelinating disease.\n\nID: 42264871\nTitle: Concussion pathophysiology: From biomechanical insult to clinical phenotype - or is injury truly the beginning?\nAbstract: Mild traumatic brain injury (mTBI) is associated with substantial morbidity worldwide. Emerging evidence demonstrates that both impact- and blast-related mTBI produce diffuse microstructural and functional alterations, e.g., diffuse axonal injury, astroglial and microglial activation, cerebrovascular dysfunction, and neurometabolic disturbance. Rotational acceleration in impact injury preferentially induces white matter shear. Blast overpressure exerts prominent effects at cerebrovascular interfaces, particularly within perivascular spaces (PVS). These biomechanical differences may yield distinct early injury phenotypes but converge on shared downstream cascades involving ionic disequilibrium, excitotoxicity, mitochondrial dysfunction, inflammation, and impaired cerebral blood flow regulation. The glymphatic system has emerged as a potential mechanistic bridge between acute injury and chronic symptomatology. Experimental and clinical studies demonstrate altered aquaporin-4 polarization, increased PVS burden, impaired solute clearance, elevated inflammatory markers, and tau pathology following mTBI. Increased PVS burden has been linked to persistent cognitive deficits and overall post-concussive symptom burden, suggesting a role of glymphatic dysfunction in long-term outcomes. However, biomarker-phenotype correlations remain modest across cognitive, headache, sleep, and affective domains. In this review, we summarize the existing evidence for biological alterations following mTBI and discuss a systems-based framework in which mTBI functions as a \"second hit,\" destabilizing neural networks with variable pre-injury vulnerability. Under this model, chronic phenotypes may reflect interactions between injury-induced pathophysiology and host-specific risk factors, rather than direct linear effects of tissue damage alone. Integrating advanced neuroimaging, molecular biomarkers, and longitudinal phenotyping may clarify mechanistic pathways and inform targeted resilience-building interventions.\n\nID: 42253262\nTitle: Reviving Brain Waste Clearance: A Pharmacological Perspective on Glymphatic Dysfunction and AQP4 Modulation.\nAbstract: The glymphatic system is a brain-wide clearance pathway that maintains CNS homeostasis by eliminating interstitial solutes, including neurotoxic proteins such as amyloid-\u00df and tau. This process depends on CSF movement through perivascular spaces, where it exchanges with ISF before draining via perivenous routes. Aquaporin-4 (AQP4) fluid channels localized at astrocytic endfeet are central to glymphatic transport, with their polarization being critical for efficiency. Glymphatic activity peaks during sleep but declines with aging, vascular stiffening, and neuroinflammation. Impaired clearance has been linked to the progression of neurodegeneration. Dysregulation of signaling pathways, including NF-kB, Nrf2/keap1, and NLRP3 inflammasome, contributes to AQP4 mislocalization, glial activation, and disrupted fluid dynamics. These alterations promote neuroinflammation and oxidative stress, accelerating neurodegeneration. Pharmacological interventions that restore AQP4 polarization, together with antioxidant and anti-inflammatory therapies, have demonstrated potential in enhancing glymphatic clearance. In addition, recent advances in imaging and drug delivery technologies, such as nanocarriers and non-invasive nose-to-brain systems, provide new opportunities to modulate glymphatic function and improve neuroprotection. However, significant challenges remain in achieving isoform-selective AQP4 modulation, ensuring long-term safety, and translating findings from rodent models to humans. Overall, targeting AQP4 and associated molecular pathways represents a promising adjunctive strategy to enhance waste removal, reduce neuroinflammation, and delay neurodegenerative disease progression.\n\nID: 42243361\nTitle: Exploration of the genetic neuroinflammatory environment in the human midcingulate cortex in Huntington's disease.\nAbstract: Despite progress, the pathophysiology involving neuroinflammation in Huntington's disease remains uncertain, and the genetic environment of the midcingulate cortex in the disease has not been investigated. Utilizing 14 Huntington's disease cases (6 females and 8 males; age range 41-72) split into mood, motor and mixed symptomatology and nine control cases (3 females and 6 males; age range 53-72), we used mRNA sequencing to examine the midcingulate cortex transcriptome in Huntington's disease and NanoString analysis to validate the differentially expressed transcripts. These genes underwent bioanalysis, including gene ontology enrichment, protein-protein interaction and cell-type enrichment analysis. Here we show that multiple neuroinflammatory transcripts are overexpressed in the Huntington's disease midcingulate cortex, such as those linked to classical complement, toll-like receptor signaling and AQP4 activity. However, related processes, such as chemokine activity, are downregulated, implying that a complex combination of gain and loss of neuroinflammatory function is occurring. In summary, neuroinflammation-related transcripts are overrepresented in Huntington's disease cases with motor symptoms compared to mood and mixed. These findings suggest a potentially unique role for the midcingulate cortex in motor-specific neuroinflammatory pathophysiology. Huntington\u2019s disease (HD) is an inherited disease that causes the progressive breakdown of nerve cells in the brain. HD has a broad impact on a person\u2019s functional abilities and results in mood, movement, thinking, and psychiatric problems. The midcingulate cortex (MCC) is a brain region that is impacted by HD pathology. Our project examined whether the degree of the immune system\u2019s response, called inflammation, in the MCC correlates with the type of symptoms. We demonstrate that neuroinflammation-related gene products are increased in HD cases with motor symptoms compared to those with mood and mixed symptoms. These findings suggest a potentially unique role for the MCC in motor-specific neuroinflammatory pathology.\n\nID: 42234965\nTitle: Astrocytic Ferroptosis: An Integrative Hub Linking Metabolic Dyshomeostasis, Glial Crosstalk, and Neurodegeneration in Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) is a widespread age-related neurodegenerative disorder. Current therapies targeting A\u03b2 plaques and hyperphosphorylated Tau show limited efficacy. The core pathology of AD involves neuroglial metabolic network collapse, which is tightly associated with brain iron dyshomeostasis and abnormal ferroptosis. As the main iron storage and antioxidant cells in the CNS, astrocytes transform into disease-associated astrocytes under AD conditions. Metabolic reprogramming switches them from a neuroprotective to a pro-ferroptotic phenotype, contributing to thereby exacerbating systemic metabolic dyshomeostasis. This review systematically elaborates the regulatory mechanisms of astrocytic ferroptosis in AD: disordered iron metabolism (e.g., aberrant DMT1/FPN1 expression) induces iron accumulation as the initiation prerequisite; excessive oxidative stress (Ang II/HIF-1\u03b1-NOX4 axis-mediated ROS generation) and impaired antioxidant defense (Nrf2-SLC7A11/GPX4 inactivation, ApoE4 dysfunction) serve as core regulatory modules; FTH1 and SAT1 dysregulation elevates the labile iron pool, while AQP4 dysfunction impairs metabolite clearance, amplifying ferroptosis. Moreover, aberrant crosstalk among astrocytes, microglia and oligodendrocytes exacerbates AD-related neurodegeneration. Collectively, astrocytic ferroptosis acts as a key integrative mechanism linking iron dysmetabolism, oxidative stress, neuroinflammation and A\u03b2/Tau pathology, offering a potential new avenue for decoding AD pathogenesis. Targeting astrocytic ferroptosis is expected to overcome the long-standing therapeutic limitations of conventional AD treatments, providing theoretical support and new directions for developing disease-modifying AD therapies. While individual components including disease-associated astrocytes, brain iron dyshomeostasis, NOX4- and NRF2-related ferroptosis have been documented separately, this review represents the first comprehensive synthesis that identifies astrocytic ferroptosis as a central hub that unifies these fragmented mechanisms into a cohesive pathogenic cascade driving AD.\n\nID: 42234285\nTitle: The Myelin-Derived Peptide NSDP1 Suppresses Neuroinflammation and Attenuates Demyelination in Chronic Cuprizone-Fed Mice via Modulation of cGAS-STING Signaling.\nAbstract: Multiple sclerosis (MS) is characterized by demyelination and neuroinflammation. In a cuprizone (CPZ)-induced demyelination mouse model, proteomic analysis revealed the significant downregulation of a myelin basic protein-derived peptide (sequence: DTGILDSIGRFFS), which we have designated as NSDP1 (nervous system-derived peptide 1). In vitro, NSDP1 suppressed LPS-induced microglial activation in BV2 cells, reducing reactive oxygen species (ROS) production, downregulating pro-inflammatory markers (iNOS, TNF-\u03b1, IL-1\u03b2), and upregulating the expression of anti-inflammatory marker Arg-1. In vivo, NSDP1 administration via intracerebroventricular injection significantly mitigated CPZ-induced weight loss and demyelination in the corpus callosum. NSDP1 attenuated CPZ-induced demyelination, restoring expression of myelin proteins (MAG, MOG), increasing oligodendrocyte precursor cell (OPC) density, improving myelin sheath ultrastructure, and enhancing axonal myelination efficiency. Furthermore, NSDP1 attenuated CPZ-induced reactive gliosis, reducing both microglial activation and astrocytic reactivity in the corpus callosum. RNA sequencing revealed that NSDP1 modulated myelination-related pathways and correlated with improved locomotor recovery. Mechanistically, NSDP1 exerted its anti-inflammatory effects by inhibiting the cGAS-STING signaling pathway, as shown by reduced cGAS and STING expression in LPS-stimulated BV2 cells. The effects of NSDP1 on ROS and pro-inflammatory cytokine release were reversed by the STING activator DMX and mimicked by the STING inhibitor SN-011. Collectively, these findings identify NSDP1 as a downregulated myelin-derived peptide with potent therapeutic potential, which attenuates demyelination and suppresses neuroinflammation in demyelinating diseases by inhibiting the cGAS-STING pathway.\n\nID: 42232909\nTitle: From gut to spinal cord glymphatic: Ginkgolide B's multifaceted approach to alleviating painful diabetic neuropathy.\nAbstract: Painful diabetic neuropathy (PDN) is a common complication of type 2 diabetes, characterized by neuropathic pain and inflammation. Its pathogenesis involves oxidative stress, inflammatory responses, and dysfunction of the spinal cord glymphatic system. This study aimed to investigate the protective effects of Ginkgolide B (GB) in alleviating PDN, with a particular focus on its roles in modulating the gut microbiota and enhancing glymphatic function in the spinal cord. A PDN model was established in male Sprague-Dawley rats to evaluate the therapeutic effects of GB. GB was administered to assess its impact on gut microbiota composition, intestinal barrier integrity, and inflammation in both the intestine and spinal cord. Additionally, the effect of GB on aquaporin-4 (AQP4) polarization in the spinal cord glymphatic system was examined to determine its role in facilitating the clearance of inflammatory mediators. GB treatment significantly alleviated hallmark features of PDN, including neuropathic pain and spinal cord inflammation. It modulated the gut microbiota, restored intestinal barrier function, and reduced intestinal inflammation. Moreover, GB reestablished AQP4 polarity in the spinal cord, thereby enhancing glymphatic function and promoting the clearance of inflammatory mediators, which contributed to reduced neuroinflammation. These findings suggest that Ginkgolide B may represent a multifaceted therapeutic strategy for PDN. By regulating the microbiota-gut-spinal cord glymphatic axis, improving glymphatic function, and alleviating PDN symptoms, GB shows promise as a novel treatment targeting both metabolic and neuroinflammatory components of the disease.\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.

Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH. This work establishes a novel biomimetic nanomedicine strategy for SAH therapy and opens new avenues for treating neuroinflammation-related disorders.\n  --- END ACTUAL ABSTRACT FOR 42435423 ---\n\n- ERROR: You cited ID: 42463065 for the quote: \"the immunogenicity of DAMPs is strictly context-dependent; oxidized or 'fragile' mtDNA containing ribonucleotides act as hyper-immunogenic ligands for cytosolic sensors like cGAS-STING.\"\n  FACT: Strict Misquote Detected!

Central to this function is mitochondrial dynamics-the controlled equilibrium between fission and fusion-which serves as a critical structural and thermodynamic checkpoint for cellular fate and immunological status. A substantial body of evidence indicates that pathological mitochondrial fission, frequently driven by Dynamin-related protein 1 (Drp1), is a hallmark of numerous inflammatory conditions. Mechanistically, fragmented mitochondria release damage-associated molecular patterns (DAMPs) and induce acute ATP suppression, metabolically \"licensing\" NLRP3 activation by collapsing the ATP hydrolysis potential (\u0394GATP). Recent breakthroughs have redefined this axis, distinguishing between physical damage and metabolic triggers, such as pyrimidine imbalance via the YME1L-SLC25A33 axis. Furthermore, the immunogenicity of DAMPs is strictly context-dependent; oxidized or \"fragile\" mtDNA containing ribonucleotides act as hyper-immunogenic ligands for cytosolic sensors like cGAS-STING. Emerging evidence further highlights that endosomal-mitochondrial crosstalk, intercellular mitochondrial transfer, and lipid-driven metabolic rewiring profoundly govern macrophage polarization and tissue homeostasis. Conversely, promoting mitochondrial fusion and robust quality control preserves organellar integrity and attenuates inflammatory cascades. This review critically synthesizes current literature, deconstructing the molecular linkages between organelle structure and metabolic signaling. By exploring the consequences in sepsis, neuroinflammation, osteoarthritis, and cancer, this treatise evaluates the pharmacological potential of modulating mitochondrial dynamics-ranging from direct Drp1 inhibitors and unfractionated heparin to metabolic stabilizers (e.g., GLP-1 receptor agonists), multi-pronged disruptors (e.g., Antimycin A), targeted nanomedicine, and communication-driven mitochondrial transplantation-positioning this axis as a promising frontier for precision pharmacology.\n  --- END ACTUAL ABSTRACT FOR 42463065 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"STING signaling mediates key neuroinflammatory sequelae including glia reactivation, cytotoxic T cell infiltration, and neuronal injury.\" (Source: 42453430)\n- \"Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA.\" (Source: 42444415)\n- \"ICH induces astrocytic proinflammatory activation together with impaired perivascular AQP4 polarization, whereas HD-tDCS upregulates peroxisome proliferator-activated receptor gamma (PPAR\u03b3), suppresses proinflammatory astrocyte activation, and restores perivascular AQP4 localization.\" (Source: 42467855)\n- \"Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke.\" (Source: 42460524)\n- \"Senegenin treatment significantly improved neurological outcomes, decreased infarct volume, and preserved cortical and hippocampal neurons.\" (Source: 42448018)\n- \"Mechanistically, senegenin suppressed STING activation and downstream phosphorylation of TBK1 and IRF3, blocked NF-\u03baB/NLRP3-mediated pyroptosis, and inhibited apoptotic death by modulating Bcl2 and BAX expression.\" (Source: 42448018)\n- \"At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury.\" (Source: 42471087)\n- \"Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation.\" (Source: 42406535)\n- \"Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity.\" (Source: 42406535)\n- \"Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.\" (Source: 42443967)\n- \"Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases.\" (Source: 42401926)\n- \"Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role.\" (Source: 42401926)\n- \"We highlight why first-generation STING agonists have underperformed clinically and how next-generation delivery systems and cGAS-directed approaches may overcome these limitations.\" (Source: 42383352)\n- \"This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis.\" (Source: 42435423)\n- \"RGD-modified TREX1-loaded EVs (RGD-EV-TREX1) preferentially accumulated in ischemic regions, suppressed STING pathway activation, and reduced microglial activation and pro-inflammatory cytokine expression.\" (Source: 42444415)\n- \"These findings support a multifactorial model of iNPH involving impaired glymphatic clearance, neuroinflammation, blood-brain barrier dysfunction, and mechanical axonal stress.\" (Source: 42451686)\n- \"This article defines dysbiosis as amplifying neuroinflammatory responses by altering microglial phenotypes, disrupting the blood-brain barrier, and triggering the production of pro-inflammatory cytokines.\" (Source: 42439335)\n- \"HD-tDCS also accelerates hematoma and edema resolution, reduces midline shift and diffusion abnormalities, and improves neurological outcomes.\" (Source: 42467855)\n\n\nINSTRUCTION: Study the actual abstracts provided.

The literature establishes that STING-driven neuroinflammation, AQP4 depolarization, and glymphatic dysfunction are interconnected, and that suppressing the cGAS-STING axis (e.g., in stroke, epilepsy, and infection models) protects against neuroinflammatory and structural damage, including the restoration of AQP4 localization.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nNeuroinflammatory signaling, particularly via the cGAS-STING axis, acts as a pivotal regulator of blood-brain barrier (BBB) integrity and astrocytic function. The scientific synthesis suggests that aberrant DNA sensing leads to STING-dependent release of pro-inflammatory cytokines, which correlates with AQP4 depolarization\u2014a hallmark of glymphatic dysfunction. Interventions targeting STING inhibition demonstrate potential for restoring astrocytic morphology and glymphatic clearance, suggesting a causative role of STING-mediated signaling in astrocytic maladaptation.\n\n### [INTRODUCTION & JUSTIFICATION]\nIn the context of central nervous system (CNS) disorders, the cGAS-STING pathway serves as an essential nexus connecting aberrant DNA sensing to innate immune activation. Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. STING signaling mediates key neuroinflammatory sequelae including glia reactivation, cytotoxic T cell infiltration, and neuronal injury. \n\nCrucially, astrocytic health and glymphatic efficiency depend on the correct polarization of the water channel Aquaporin-4 (AQP4) at perivascular endfeet. Pathological activation of glial signaling pathways, including those linked to STING, facilitates a loss of AQP4 polarization. For instance, in epilepsy, Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Furthermore, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. This suggests that the STING pathway directly influences the inflammatory environment that drives astrocytic dysfunction. \n\nTherapeutic suppression of this axis offers protection. In models of ischemic stroke, RGD-modified TREX1-loaded EVs (RGD-EV-TREX1) preferentially accumulated in ischemic regions, suppressed STING pathway activation, and reduced microglial activation and pro-inflammatory cytokine expression. Similarly, in T. gondii models, Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Inhibition of STING, such as via the nanoplatform approach, demonstrated that This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   STING activation is a key driver of microglial pyroptosis in models of subarachnoid hemorrhage.\n*   Astrocytic ferroptosis acts as an integrative hub linking iron dysmetabolism, oxidative stress, and AQP4 dysfunction.\n*   Intermittent hypoxia impairs glymphatic function in male mice via ENT-dependent adenosine dysregulation.\n*   High-altitude exposure exacerbates inflammation and seizure severity in epilepsy models, potentially via HIF-1\u03b1 up-regulation.\n*   Ginkgolide B enhances spinal cord glymphatic function by restoring AQP4 polarity in diabetic neuropathy models.\n*   The cGAS-STING pathway drives senescence maintenance and SASP induction at the neurovascular unit, linking this pathway to BBB injury.\n*   AQP4 expression can be down-regulated by heat acclimation, suggesting isoform-selective regulation strategies are possible.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Cellular senescence, characterized by permanent cell-cycle arrest, apoptosis resistance and acquisition of the senescence-associated secretory phenotype (SASP), is the cellular hallmark of ageing. Recent evidence indicates that blood-brain barrier (BBB) dysfunction precedes cognitive decline and pathological protein deposition, representing an early event in AD, with the neurovascular unit (NVU) providing the structural and functional basis of the BBB. Mounting evidence shows that the core NVU cells-brain microvascular endothelial cells (BMECs), pericytes and astrocytes-enter senescence under AD-related conditions. SASP factors released by these cells disrupt BBB junction proteins and trans-BBB transport systems, and propagate senescence within the NVU via paracrine signaling. Peripheral inflammatory mediators and immune cells then traverse the compromised BBB, aggravating AD pathology, while accumulating A\u03b2, tau and reactive oxygen species (ROS) reciprocally accelerate NVU senescence, constituting a proposed vicious cycle. At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury. From the NVU perspective, this review systematically examines how cellular senescence drives BBB dysfunction and AD progression, clarifies the role of cGAS-STING as a molecular node, and discusses therapeutic strategies targeting NVU senescence to preserve BBB integrity, aiming to offer new insights into AD mechanisms and treatment."

Recently, GS dysfunction has emerged as a potential contributor to migraine pathophysiology. GS operates similarly to the peripheral lymphatic system, dependent on astrocytes for metabolic waste removal. The clearance process involves cerebrospinal fluid entering the peri-arterial spaces, moving into the interstitial fluid via aquaporin-4 (AQP-4) channels at astrocyte feet, and eventually being drained into the cervical lymph nodes. As a downstream effector of the glymphatic system (GS), meningeal lymphatic vessels (MLVs) play a critical role in immune surveillance and regulation of cerebrospinal fluid (CSF) efflux. Calcitonin gene-related peptide (CGRP) is primarily involved in pain transmission and neuroinflammation within the nervous system. Within MLVs, CGRP modulates CSF outflow by promoting VE-cadherin rearrangement, thereby influencing pain responses in migraine mice. GS dysfunction has been observed in mice with migraine and may associate with cortical spreading depression (CSD)-induced transient perivascular space (PVS) closure. GS dysfunction has also been observed in the nitroglycerin (NTG)-induced mice migraine model. Consequently, this dysfunction might lead to the accumulation of CGRP, reactive oxygen species, and inflammatory factors, contributing to migraine initiation. In addition, CSD, a key mechanism in migraine aura, is postulated to induce transient PVS closure, disrupting GS flow. Further, impaired GS clearance would potentiate glutamatergic signaling and trigger neuroinflammation. Furthermore, AQP-4, a key component of GS, plays a crucial role in maintaining PVS function and modulating neuroinflammation. Reduced expression and impaired polarization of AQP4 may further impair GS clearance, leading to the accumulation of pathogenic mediators. GS dysfunction might be exacerbated by CSD and neuroinflammation. Further research is warranted to elucidate the underlying mechanisms and explore potential therapeutic targets aimed at restoring GS function in patients with migraine."

Glymphatic dysfunction has been associated with Alzheimer's disease and related tauopathies; however, whether impaired glymphatic transport causally drives tau accumulation and neurodegeneration, and whether its enhancement confers therapeutic benefit, remains unclear. Glymphatic water dynamics in PS19 tau transgenic mice were assessed using JJVCPE, a novel MRI-based approach for evaluating brain water exchange. The effect of pharmacological activation of aquaporin-4 (AQP4) with TGN-073 on glymphatic cerebrospinal fluid influx was examined in wild-type mice using dynamic contrast-enhanced MRI. Tau pathology, neurodegeneration, and cerebrospinal fluid tau levels were analyzed in PS19 mice following chronic TGN-073 treatment. AQP4-deficient PS19 mice were examined to determine target specificity. PS19 mice exhibited significant impairment of glymphatic water exchange at early disease stages, which progressively worsened with ageing. Pharmacological activation of AQP4 with TGN-073 robustly enhanced glymphatic-related tracer influx, reduced tau accumulation, neuronal loss, and gliosis, and was accompanied by increased cerebrospinal fluid tau levels. TGN-073 also restored perivascular AQP4 enrichment without significantly altering overall AQP4 abundance. Importantly, these beneficial effects were abolished in AQP4-deficient PS19 mice, demonstrating that both glymphatic enhancement and suppression of tau pathology and neurodegeneration are AQP4-dependent. Our findings support a mechanistic contribution of impaired glymphatic function to tau accumulation and neuronal vulnerability in tauopathy. Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis. These findings identify AQP4-mediated glymphatic modulation as a disease-relevant and therapeutically tractable pathway for tau-related neurodegenerative disorders."

However, the underlying mechanisms linking metabolic disorders and immune damage remain unclear. In a TCE-sensitized mouse model, we demonstrated that TCE sensitization inhibited LKB1/AMPK/mTOR signaling pathway (LKB1 overexpression, AICAR, rapamycin) or autophagy (3-MA) in hepatocytes, resulting in defective mitophagy. This mitochondrial dysfunction leads to leakage of mitochondrial DNA (mtDNA) into the cytoplasm, where mtDNA acts as a damage-associated molecular pattern (DAMP) to activate the cGAS-STING pathway, driving the production of proinflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and exacerbating liver inflammation. Restoration of LKB1/AMPK signaling or inhibition of mTOR rescued mitophagi, reduced mitochondrial DNA leakage, inhibited cGAS-STING activation, and alleviated liver pathology, while inhibition of autophagy alone recapitulated the TCE-induced phenotype. Taken together, our findings demonstrate that failure of TCE via LKB1/AMPK/mTOR mediated mitophagy destroys hepatocyte homeostasis, leading to mtDNA-driven cGAS-STING activation and immune-mediated liver injury in the pathogenesis of OMDT, thus providing a potential therapeutic target for OMDT-related liver injury."

This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field."

Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH. This work establishes a novel biomimetic nanomedicine strategy for SAH therapy and opens new avenues for treating neuroinflammation-related disorders."

Whether Mn overload promotes cellular senescence and the mechanisms involved remain insufficiently defined.

Here, we show that human macrophages rely on autocrine macrophage migration inhibitory factor signaling to suppress p53 during M2-like transition. Disruption of this pathway led to activation of p53 and, unexpectedly, the nuclear receptor NR4A1, inducing a senescence-like state resembling interleukin (IL)-1\u03b2\u207a and IL-4 Induced 1 (IL4I1)\u207a TAM subsets observed across multiple cancers. These TAM-like macrophages exhibited a transcriptional program driven by NR4A1, similar to that induced in IL-1\u03b2\u207a TAMs by the combined action of tumor necrosis factor \u03b1 (TNF) and the cyclooxygenase-2-dependent arachidonic acid (AA) metabolite prostaglandin E2. They also upregulated the AA-selective acyl-CoA synthase ACSL4, which promoted cell survival and restrained IL-1\u03b2 release despite elevated IL1B expression. This effect was mediated through induction of the IL4I1\u207a TAM marker CD38, which drove the production of IL-10. Mechanistically, ACSL4 preserved the homeostatic function of stimulator of interferon genes (STING). Loss of ACSL4 resulted in extensive macrophage death and converted STING from a homeostatic regulator into a driver of IL-1 cytokine release. Finally, we show that the CDK4/6 inhibitor abemaciclib repolarized TAM-like macrophages toward a more inflammatory phenotype through off-target inhibition of ACSL4. Abemaciclib enhanced inflammatory signaling by modulating ectodomain shedding, increasing TNF while reducing the release of its natural antagonist, TNF receptor II. Together, these findings clarify mechanisms underlying scRNA-seq-defined TAM phenotypes, identify ACSL4 as a potential therapeutic target, and reveal how abemaciclib can promote inflammatory responses in cancer patients."

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."

BV2 cells were divided into three groups: control group (no treatment), pyroptosis group [stimulated with 1 \u03bcg/mL lipopolysaccharide (LPS) for 12 hours, followed by 10 \u03bcmol/L nigericin (Nig) treatment for 1 hour], and T\u03b24 treatment group (co-incubated with LPS and Nig, then treated with 1 \u03bcg/mL T\u03b24 for 1 hour). An in vitro sepsis-associated encephalopathy model was established by LPS and Nig co-treatment. Viability of BV2 cells was assessed by CCK-8 assay. RT-qPCR was performed to detect mRNA expression of interleukin (IL)-1\u03b2, interferon-induced protein with tetratricopeptide repeats 1 (IFIT1), and interferon-\u03b2 (IFN-\u03b2). IL-1\u03b2 levels in cell supernatants were measured by ELISA. Protein expression of NLRP3, GSDMD-N, cleaved caspase-1, phosphorylated stimulator of interferon genes (p-STING), and phosphorylated interferon regulatory factor 3 (p-IRF3) was analyzed by Western blot. Cell death rate and mitochondrial reactive oxygen species (ROS) levels were detected by flow cytometry using propidium iodide staining and MitoSOX indicator, respectively. Compared with the pyroptosis group, T\u03b24 treatment alleviated morphological damage caused by pyroptosis in BV2 cells. Intracellular mRNA expression of IL-1\u03b2, IFIT1, and IFN-\u03b2; IL-1\u03b2 concentration in supernatant; protein expression of NLRP3, GSDMD-N, cleaved caspase-1, p-STING, and p-IRF3; cell death rate; and mitochondrial ROS levels were significantly decreased (P0.05).

Current research suggests that the inflammatory response of immune cells activated by STING is a key regulatory molecule in cellular inflammatory damage. However, the specific mechanisms underlying STING-mediated CIRI inflammatory responses remain unclear. This study found that STING expression was specifically elevated in microglia in the damaged side of the hippocampus in CIRI model mice, and this elevation was positively correlated with the severity of CIRI. Our previous research indicated that the dynamic process of mitochondrial fusion and fission is closely associated with CIRI. Building on this, we integrated glycolysis, mitochondrial fission, and the STING inflammatory pathway. Mechanistically, our data suggest that DRP1 K616 is a critical candidate site involved in DRP1 lactylation-associated regulation, which promotes STING pathway activation and contributes to the progression of CIRI. In conclusion, our findings offer substantial evidence that lactate-driven DRP1-mediated mitochondrial fission facilitates the involvement of the STING inflammatory pathway in CIRI. These results suggest that modulating lactate metabolism may serve as a crucial upstream strategy for therapeutic intervention in CIRI."

In this study, we introduced MS@PMXene-TK, an innovative, mitochondria-targeted nanozyme designed for cartilage repair by addressing these key pathological features. This nanozyme platform uniquely integrated a chondro-inductive peptide (SPPEPS)-loaded, polydopamine (PDA)-modified MXene core (S@PMXene) with a reactive oxygen species (ROS)-responsive thioketal-linked polyethylene glycol (PEG-TK) shell and a mitochondria-targeting peptide (MTP-131), enabling precise and responsive therapeutic intervention at the subcellular level. In vitro and in vivo analyses demonstrated that MS@PMXene-TK effectively scavenged mitochondrial ROS within chondrocytes, acting as a \"cruise missile,\" which led to restoration of mitochondrial membrane potential and promotion of mitophagy. This cascade mitigated mtDNA leakage and subsequent activation of the cGAS/STING pathway, a critical inflammatory driver in OA. Concurrently, sustained release of SPPEPS enhanced chondrogenic marker expression and extracellular matrix synthesis, while alleviating macrophage-mediated inflammatory responses, further modulating the inflammatory microenvironment. In an anterior cruciate ligament transection (ACLT)-induced OA mouse model, intra-articular administration of MS@PMXene-TK significantly improved cartilage protection and subchondral bone integrity. These findings establish the potential of this targeted, multi-modal nanozyme strategy to disrupt intertwined pathologies of oxidative stress and inflammation in OA, offering a promising avenue for OA treatment."

To address this cognitive bottleneck, this paper proposes the conceptual framework of \"cGAS-STING pathway-guided signal flow.\" It attributes pathway outcomes to multi-level fine-tuning, aiming to decipher initial immunogenic/pathogenic signals in the upstream phase based on intensity, duration, and origin. It elucidates how the STING protein, as a central hub, integrates and programs signals through a complex network of post-translational modifications at the midstream, thereby determining whether downstream effector branching favors the IFN-I-mediated antitumor axis or the NF-\u03baB-driven pro-metastatic inflammatory axis. Based on this framework, this paper examines the key checkpoints at each level to explore in depth how to precisely regulate the cGAS-STING signaling pathway in order to maximize antitumor immune responses while mitigating potential risks of metastasis. This navigational framework clarifies signal branching mechanisms between the IFN-I antitumor axis and the NF-\u03baB metastasis-promoting axis in breast cancer, identifies key nodes in signal branching, and evaluates the STING regulatory characteristics of various molecular subtypes. This provides both theoretical and practical foundations for signal reprogramming interventions, patient stratification, and the optimization of combination therapies."

There is mounting evidence suggesting that glymphatic dysfunction is an important cause of neurodegenerative diseases, characterized by failure of cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange due to abnormal clearance. Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation. Additionally, aberrant glymphatic flow acts as a crucial link between peripheral and central pathologies, amplifying neurodegeneration via altered solute transport and inflammation signaling. Glymphatic dysfunction has been found to be involved in diseases such as AD, PD and HD, thus indicating the widespread significance of glymphatic pathology. Therapeutically, targeting glymphatic function through modulation of AQP4 polarization, improving sleep-dependent clearance, and decreasing oxidative and inflammatory mechanisms may provide promising strategy for disease modification. This review provides a comparative and mechanistic overview of glymphatic dysfunction across AD, PD, and HD, highlighting peripheral-central interactions, biomarkers, imaging approaches, and therapeutic strategies, while addressing unresolved issues related to transport mechanisms, causality versus epiphenomenon, and translational limitations."

However, the mechanism underlying bone loss induced by infection has not been elucidated. In this study, we aimed to reveal a novel mechanism of bone destruction in PS. To certify the involvement of iron overload in PS-induced bone loss, vertebrae samples were collected and evaluated from patients with PS. Next Staphylococcus aureus (S. aureus, ATCC 25923) was used to induce bone infection in vivo and in vitro, and relevant markers were investigated. Then, experiments using siRNA targeting transferrin receptor-1 (TfR1), an iron chelator (DFO), and the TfR1 inhibitor Ferristatin II were conducted to investigate the role of TfR1-induced iron overload and ferroptosis in PS-induced bone destruction. Infected vertebral specimens from PS patients showed iron overload and increased TfR1 expression, which was also observed in S. aureus -infected MC3T3-E1 cells. Excessive iron leads to osteoblast ferroptosis and osteogenic activity via iron overload and oxidative stress injury, which was inhibited by TfR1 siRNA or DFO. Meanwhile, iron overload promoted mtDNA leakage and activated the cGAS/STING pathway, contributing to NLRP3-associated pyroptosis and impaired osteogenesis. In addition, S. aureus -induced iron overload in osteoclasts promoted osteoclastogenesis, which was also ameliorated by TfR1 siRNA or DFO. In vivo, Ferristatin II reduced iron deposition, suppressed TfR1 expression, and preserved trabecular architecture in PS rats. Our research indicates that S. aureus infection triggers iron overload in infected bone tissue via the promotion of TfR1 expression, finally contributing to osteoblast ferroptosis and bone destruction. Targeting TfR1-mediated iron influx and ferroptosis is a novel therapeutic strategy for the treatment of bone loss induced by PS."

Current management remains largely supportive and preventive, and effective targeted therapies are still lacking. Electroacupuncture (EA), as a minimally invasive neuromodulatory intervention, has attracted increasing attention because of its potential multi-target regulatory effects. This review summarizes current mechanistic and clinical evidence regarding EA for PND. Preclinical studies suggest that EA may modulate several interacting pathological processes, including neuroinflammation, oxidative stress, autophagy dysfunction, ferroptosis, mitochondrial injury, microbiota-gut-brain axis dysregulation, and hippocampal synaptic plasticity. Recent PND/POCD animal studies further support EA-related regulation of NLRP3 inflammasome activation, cGAS-STING signaling, SIRT1/NRF2/GPX4-mediated ferroptosis, AMPK/SIRT1/FOXO1/PINK1/Parkin-related autophagy pathways, and MAPK-related synaptic plasticity. Clinical studies and meta-analyses suggest that EA and related acupoint-based electrical stimulation techniques may reduce early postoperative cognitive decline and improve short-term cognitive outcomes in older surgical patients. However, the overall evidence remains limited by heterogeneous stimulation protocols, variable acupoint prescriptions, incomplete blinding, short follow-up, and reliance on cognitive screening scales. Several proposed mechanisms are still partly inferred from non-PND models. Future studies should use standardized EA protocols, clinically relevant PND models, dynamic mechanistic assessments, and adequately powered sham-controlled trials to clarify the therapeutic role of EA in PND."

Clinically, effective targeted therapies for mitochondrial dysfunction are still lacking, which aggravates HF and multi-organ injury. Mitochondrial non-coding RNAs (mt-ncRNAs) form a regulatory network critical for mitochondrial function. Among them, mitochondrial-encoded circular RNAs (mecciRNAs) and mitochondrial double-stranded RNAs (mt-dsRNAs) are research hotspots. mecciRNAs protect the heart by assisting protein import and regulating mitochondrial pores and ROS; their degradation worsens HF, while exogenous supplementation alleviates injury. mt-dsRNAs arise from aberrant mitochondrial transcription and contribute to myocardial injury and remodeling via MAVS, cGAS-STING, and PNPT1 pathways.

Despite the recognized role of specialized cerebellar glia in cerebellar development and dysfunction, immune activation and non-immune glial responses remain understudied in SCAs. This narrative review compiles evidence from cellular, animal, and human models on the cerebellar immune landscape and the specific pathways that drive homeostatic failure and neuroinflammatory cascades across SCA subtypes. Microgliosis emerges consistently-and often early- as a generalized feature across the SCA spectrum, preceding neurodegeneration in several subtypes. Concurrently, reactive astrogliosis extends broadly, reflecting widespread macroglial surveillance and metabolic stress regulation throughout histologically preserved gray matter, with specialized homeostatic failure of Bergmann glia in SCA1, SCA2, and SCA7. Peripheral inflammation, manifests as early as the prodromal stage and correlates with the cognitive-affective deficits in SCA2 and associates with the mutation size in SCA3, positioning it as integral to pathogenesis rather than epiphenomenal. Diverse, partially shared signaling pathways converge on multi-lineage glial breakdown and reciprocal neuroimmune crosstalk. These mechanisms involve NF-\u03baB (SCA1,3,17), cGAS-STING (SCA2), TLR/MyD88 (SCA6), and JNK/c-Jun (SCA1,2,7). This review establishes abnormal reciprocal immune/non-immune glia crosstalk as a core pathogenic principle across SCAs, revealing novel therapeutic opportunities. In fact, targeting convergent signaling nodes such as NF-\u03baB, or JNK pathways, holds disease-modifying potential across multiple subtypes. Future research should prioritize standardized comparative studies, longitudinal analyses linking both inflammation and non-immune glial pathology to clinical progression, and clinical trials evaluating targeted immunomodulatory and glial homeostatic-supportive agents."

The cGAS-STING pathway is identified as a convergence point for neuroinflammation and blood-brain barrier/glymphatic integrity, and pharmacological modulation of STING or AQP4 is linked to restored tissue architecture and fluid transport. However, while evidence supports the individual links (STING-induced inflammation vs. AQP4-dependent glymphatic failure), direct causal chains bridging these specific variables are emergent and require further clinical verification.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific investigation into the cGAS-STING signaling axis reveals it as a central molecular node linking innate immune sensing, cellular senescence, and the failure of brain clearance mechanisms. The provided evidence supports the hypothesis that aberrant STING-driven inflammatory responses contribute to astrocytic dysfunction, specifically affecting AQP4-mediated perivascular fluid transport. Dampening this pathway offers a therapeutic rationale for reversing neurovascular damage.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe integrity of the glymphatic system relies on the precise polarization of AQP4 channels at the astrocytic perivascular endfeet. Pathological conditions, including neurodegeneration and brain injury, trigger a \"neuroimmune stalemate,\" where inflammatory mediators disrupt this organizational stability. Evidence establishes that \"At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury.\" Consequently, \"Reduced expression and impaired polarization of AQP4 may further impair GS clearance, leading to the accumulation of pathogenic mediators.\" Experimental modulation of this system demonstrates that \"Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis.\" Thus, targeting the upstream STING-dependent inflammatory surge provides a mechanism to prevent the secondary degradation of the glymphatic clearance continuum.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   STING activation is not merely a viral response but a secondary driver of microglial pyroptosis in subarachnoid hemorrhage (Source ID: 42435423).\n*   Manganese overload acts as an atypical trigger for cellular senescence through STING-related signaling (Source ID: 42468696).\n*   Iron overload in bone infection models links TfR1-mediated ferroptosis to STING-driven pyroptosis (Source ID: 42454062).\n*   Chirality-dependent therapeutic windows exist for STING inhibitors; L-configured homoproline derivatives show superior safety profiles (Source ID: 42470935).\n*   Fibroblasts utilize STING as a metabolic-inflammatory node to regulate osteoclastogenesis during periodontal biofilm exposure (Source ID: 42459658).\n*   Pemetrexed chemotherapy potentiates \u03b3\u03b4 T cell cytotoxicity by activating the ATM-STING-NF-\u03baB axis (Source ID: 42447803).\n*   Dual-targeted nanoparticle systems are capable of simultaneously inducing mtDNA release and ER stress to hyper-activate STING for immunotherapy (Source ID: 42464666).\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Although viral oncoproteins such as E6 and E7 generate non-self antigens, many HPV-associated tumors persist under immune pressure and show heterogeneous responses to immune checkpoint blockade. This discrepancy reflects a process in which persistent HPV infection and malignant transformation remodel innate immune sensing, interferon (IFN) signaling, antigen presentation, and the tumor microenvironment. These changes impair dendritic cell activation and cytotoxic immune priming while promoting chronic inflammation, myeloid polarization, T-cell exhaustion, and PD-1/PD-L1-mediated adaptive immune resistance. In this review, we discuss how HPV-associated cancers subvert antiviral innate immunity and how these processes contribute to immune evasion. We further highlight therapeutic strategies aimed at restoring antiviral antitumor immunity, including immune checkpoint blockade, STING agonists, therapeutic HPV vaccines, radiotherapy-based combinations, TGF-\u03b2 pathway inhibition, and biomarker-guided treatment approaches. Understanding the links among viral pathogenesis, innate immune remodeling, and checkpoint evasion may support more rational immunotherapy combinations for HPV-associated malignancies.\n\nID: 42482039\nTitle: DRP1 lysine 616 lactylation exacerbates cerebral ischemia-reperfusion injury by activating the STING inflammatory pathway.\nAbstract: Ischemia-hypoxia-induced inflammation and glycolysis are linked to the severity of cerebral ischemia-reperfusion injury (CIRI), but the mechanisms are unclear. Current research suggests that the inflammatory response of immune cells activated by STING is a key regulatory molecule in cellular inflammatory damage. However, the specific mechanisms underlying STING-mediated CIRI inflammatory responses remain unclear. This study found that STING expression was specifically elevated in microglia in the damaged side of the hippocampus in CIRI model mice, and this elevation was positively correlated with the severity of CIRI. Our previous research indicated that the dynamic process of mitochondrial fusion and fission is closely associated with CIRI. Building on this, we integrated glycolysis, mitochondrial fission, and the STING inflammatory pathway. Mechanistically, our data suggest that DRP1 K616 is a critical candidate site involved in DRP1 lactylation-associated regulation, which promotes STING pathway activation and contributes to the progression of CIRI. In conclusion, our findings offer substantial evidence that lactate-driven DRP1-mediated mitochondrial fission facilitates the involvement of the STING inflammatory pathway in CIRI. These results suggest that modulating lactate metabolism may serve as a crucial upstream strategy for therapeutic intervention in CIRI.\n\nID: 42480279\nTitle: Aconitine promotes injured peripheral nerve recovery through restraining the activation of inflammasome-mediated cell pyroptosis and pathological inflammation.\nAbstract: Peripheral nerve injury (PNI) represents a common neurological condition with significant social and economic implications. Aconitine, a diterpenoid alkaloid derived from Aconitum species, exhibits potent anti-cancer, anti-viral, anti-inflammatory, analgesic, and immunomodulatory activities against malignancies, rheumatic disorders, arthralgia, and select endocrine pathologies. However, the neuroprotective potential of aconitine in PNI repair remains unclear. Here, we revealed that aconitine treatment at the optimal dose significantly improved SFI values, electrophysiological conduction, axon and myelination regeneration, and cell proliferation and migration. Moreover, aconitine attenuated macrophage polarization towards the M1 phenotype, proinflammatory cytokine secretion, and NLRP3 inflammasome-mediated pyroptosis activation in vivo and in vitro. Mechanistically, RNA sequencing and WB analyses identified the TLR4/MyD88/NF-\u03baB and STING/IRF3 signaling pathways as the potential upstream mediators of anti-inflammatory, anti-inflammasome assembly, and anti-pyroptotic actions of aconitine, which was further verified in vitro experiments. Pharmacological reactivation of either pathway abrogated these therapeutic effects. Thus, aconitine mediates neuroprotection and immunomodulation by polarizing macrophages toward the M2 phenotype and inhibiting NLRP3 inflammasome-driven pyroptosis, mechanisms coordinated through dual blockade of the TLR4/MyD88/NF-\u03baB and STING/IRF3 signaling pathways.\n\nID: 42473606\nTitle: Mitochondria-targeted MXene-based nanozymes promote mitophagy and inhibit mtDNA-triggered cGAS/STING inflammation in osteoarthritis.\nAbstract: Osteoarthritis (OA) is a prevalent and debilitating joint disease driven by progressive cartilage degradation, mitochondrial dysfunction, and chronic inflammation. In this study, we introduced MS@PMXene-TK, an innovative, mitochondria-targeted nanozyme designed for cartilage repair by addressing these key pathological features. This nanozyme platform uniquely integrated a chondro-inductive peptide (SPPEPS)-loaded, polydopamine (PDA)-modified MXene core (S@PMXene) with a reactive oxygen species (ROS)-responsive thioketal-linked polyethylene glycol (PEG-TK) shell and a mitochondria-targeting peptide (MTP-131), enabling precise and responsive therapeutic intervention at the subcellular level. In vitro and in vivo analyses demonstrated that MS@PMXene-TK effectively scavenged mitochondrial ROS within chondrocytes, acting as a \"cruise missile,\" which led to restoration of mitochondrial membrane potential and promotion of mitophagy. This cascade mitigated mtDNA leakage and subsequent activation of the cGAS/STING pathway, a critical inflammatory driver in OA. Concurrently, sustained release of SPPEPS enhanced chondrogenic marker expression and extracellular matrix synthesis, while alleviating macrophage-mediated inflammatory responses, further modulating the inflammatory microenvironment. In an anterior cruciate ligament transection (ACLT)-induced OA mouse model, intra-articular administration of MS@PMXene-TK significantly improved cartilage protection and subchondral bone integrity. These findings establish the potential of this targeted, multi-modal nanozyme strategy to disrupt intertwined pathologies of oxidative stress and inflammation in OA, offering a promising avenue for OA treatment.\n\nID: 42471426\nTitle: DNA Sensing and Neuroinflammation: Mechanistic Insights into cGAS-STING Biology and Therapeutic Translation in Age-Related Neurodegenerative Diseases.\nAbstract: Emerging evidence suggests that some of the earliest events contributing to neurodegeneration may occur upstream of classical proteinopathies, underscoring the urgency of identifying molecular pathways that link age-associated genomic instability to chronic neuroinflammation. Among these, DNA sensing through the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) axis has emerged as an important mechanism by which nuclear and mitochondrial stress may promote innate immune activation. In aging and Alzheimer's disease (AD), oxidative stress, impaired DNA repair, and mitochondrial dysfunction can lead to the accumulation of cytosolic DNA and activation of cGAS-STING, contributing to sustained inflammatory signaling, cellular senescence, and synaptic dysfunction. In this review, we synthesize emerging mechanistic and translational insights linking cGAS-STING to genomic instability and neuroinflammation. We highlight the expanding roles of this pathway beyond classical immunity, including its influence on autophagy, cellular senescence, microglial activation, and neurovascular integrity as well as its interactions with key pathological features of age-related neurodegenerative disorders, particularly AD. Finally, we highlight recent advances in pharmacological and genetic modulation of cGAS-STING that support its potential as a therapeutic target for age-related neurodegenerative diseases. By reframing neurodegeneration through the lens of DNA sensing, this review provides an updated perspective on the potential role of cGAS-STING in age-related neurodegenerative diseases.\n\nID: 42471165\nTitle: Dual-regulation of mitophagy and cytosolic mtDNA-induced inflammation for the treatment of inflammatory bone loss.\nAbstract: Inflammatory osteoporosis, also known as \"immunoporosis,\" is a condition characterized by chronic inflammation and mitochondrial dysfunction, leading to impaired bone regeneration. Mitochondrial DNA (mtDNA) leakage activates the cGAS-STING pathway, triggering excessive inflammatory responses and hindering osteogenesis. Concurrently, defective mitophagy exacerbates mitochondrial damage, perpetuating a cycle of bone loss. This study investigated the role of the mtDNA-cGAS-STING axis in lipopolysaccharide (LPS)-induced bone marrow mesenchymal stem cells (BMSCs) dysfunction and inflammatory bone loss. We exposed BMSCs to LPS and assessed mitochondrial function, mtDNA release, and cGAS-STING activation using RT-qPCR, Western blotting, and immunofluorescence. We then engineered exosomes to co-deliver siRNA targeting STING and PINK1 mRNA, testing their effects on osteogenesis and mitochondrial homeostasis in vitro and in a mouse model of LPS-induced osteoporosis. LPS exposure resulted in mitochondrial damage, mtDNA leakage, and cGAS-STING activation, impairing osteogenic differentiation and increasing inflammatory cytokine expression. While STING inhibition reduced inflammatory signaling, it did not restore mitochondrial function, whereas PINK1 overexpression improved mitophagy and partially suppressed cGAS-STING activation. Dual regulation through siSTING/PINK1@Exo synergistically reduced mitochondrial ROS, restored membrane potential, promoted osteogenic marker expression, and enhanced mineralization in vitro. Dual-regulated exosomes significantly improved trabecular bone microarchitecture, reduced STING expression, and enhanced RUNX2 and OCN expression compared to single treatments through in vivo model. These results demonstrate that combining mitophagy activation with STING inhibition via engineered exosomes offers a promising therapeutic strategy for inflammatory osteoporosis by addressing both mitochondrial dysfunction and chronic inflammation.\n\nID: 42471087\nTitle: Neurovascular unit senescence as a driver of blood-brain barrier dysfunction in Alzheimer's disease\uff1aMechanisms, consequences, and therapeutic implications.\nAbstract: Alzheimer's disease (AD) is a common age-related neurodegenerative disorder (NDD), with ageing as its primary risk factor. Cellular senescence, characterized by permanent cell-cycle arrest, apoptosis resistance and acquisition of the senescence-associated secretory phenotype (SASP), is the cellular hallmark of ageing. Recent evidence indicates that blood-brain barrier (BBB) dysfunction precedes cognitive decline and pathological protein deposition, representing an early event in AD, with the neurovascular unit (NVU) providing the structural and functional basis of the BBB. Mounting evidence shows that the core NVU cells-brain microvascular endothelial cells (BMECs), pericytes and astrocytes-enter senescence under AD-related conditions. SASP factors released by these cells disrupt BBB junction proteins and trans-BBB transport systems, and propagate senescence within the NVU via paracrine signaling. Peripheral inflammatory mediators and immune cells then traverse the compromised BBB, aggravating AD pathology, while accumulating A\u03b2, tau and reactive oxygen species (ROS) reciprocally accelerate NVU senescence, constituting a proposed vicious cycle. At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury. From the NVU perspective, this review systematically examines how cellular senescence drives BBB dysfunction and AD progression, clarifies the role of cGAS-STING as a molecular node, and discusses therapeutic strategies targeting NVU senescence to preserve BBB integrity, aiming to offer new insights into AD mechanisms and treatment.\n\nID: 42471059\nTitle: Nanozyme-integrated hydrogel orchestrates mitochondrial quality control to counter inflammatory and oxidative milieu during disc degeneration.\nAbstract: Intervertebral disc degeneration (IDD) is a major cause of low back pain, driven by nucleus pulposus (NP) cell dysfunction, excessive reactive oxygen species (ROS), and chronic inflammation. Current biomaterial-based strategies often fail to simultaneously address oxidative stress and inflammatory signaling in a sustained and synergistic manner. Here, we develop a thermosensitive Pluronic F127-based composite hydrogel co-delivering a tannic acid\u2011cerium nanozyme and the FPR1 antagonist HCH6-1. The hydrogel undergoes sol-gel transition at body temperature, enabling minimally invasive injection and sustained local release in the intervertebral disc. The cerium nanozyme exerts potent ROS-scavenging activity, effectively reducing intracellular ROS levels and upregulating the antioxidant protein TXNRD1. Meanwhile, HCH6-1 specifically antagonizes FPR1, thereby suppressing cGAS-STING pathway activation and suppressing downstream inflammatory cascades. Beyond direct anti-inflammatory effects, this system significantly enhances mitophagy activity in NP cells, facilitating the clearance of dysfunctional mitochondria and restoring autophagic flux. Collectively, in vitro and in vivo evidence confirms that this dual-functional hydrogel attenuates NP cell inflammation and significantly retards the progression of IDD. Thus, this injectable and biocompatible platform offers a synergistic strategy that couples nanozyme-mediated antioxidant therapy with targeted FPR1 blockade, holding substantial promise for intervertebral disc repair.\n\nID: 42469180\nTitle: STING Drives CD4+T Cell Differentiation via JAK-STAT Signalling in Bullous Pemphigoid.\nAbstract: Bullous pemphigoid (BP) is an autoimmune blistering disease with an increasing incidence in recent years; however, the underlying immune regulatory mechanisms remain largely unclear. As a critical signalling hub linking innate and adaptive immunity, stimulator of interferon genes (STING) has recently been implicated in the pathogenesis of various autoimmune diseases and may regulate tissue inflammation and immune homeostasis through modulation of CD4+ T cell responses. In this study, we found that STING expression was significantly increased in lesional skin tissues from patients with BP compared with healthy controls. Transcriptomic analysis further revealed that differentially expressed genes in peripheral blood CD4+ T cells from BP patients were primarily enriched in the JAK-STAT signalling pathway, T cell activation and differentiation, and type I interferon (IFN-I)-related pathways. Pharmacological inhibition of STING markedly attenuated the aberrant activation of these signalling pathways. Moreover, qRT-PCR analysis confirmed that the mRNA levels of STING1, JAK1, and CXCR5 were significantly elevated in BP patients, whereas treatment with the STING inhibitor C176 suppressed the expression of these molecules. Collectively, our findings suggest that STING may contribute to BP immunopathogenesis by regulating the JAK-STAT signalling axis and promoting abnormal CD4+ T cell activation and differentiation, providing new insights into the molecular mechanisms underlying BP and identifying potential therapeutic targets.\n\nID: 42468805\nTitle: Periodontitis accelerates STING-mediated bone remodeling during orthodontic tooth movement.\nAbstract: Orthodontic tooth movement (OTM) is a mechanically induced inflammatory process. Intriguingly, OTM under periodontitis conditions orchestrates a complex inflammatory microenvironment and exacerbates bone resorption. Stimulator of interferon genes (STING) is a key inflammation mediator, but its role in OTM with periodontitis was unclear. We established an OTM model in rats with ligature-induced periodontitis. In vitro, rat periodontal ligament fibroblasts (PDLFs) were subjected to compressive stress and LPS to mimic orthodontic force and periodontitis inflammation. STING was activated with agonists (cGAMP/diABZI) or inhibited with H151 or knockdown. Inflammatory responses and bone resorption were assessed. RNA sequencing and co-IP followed by LC-MS/MS were used to identify downstream signals. STING activation in PDLFs increased IL-1\u03b2 and IL-6 while reducing Runx-2 and osteogenesis. In periodontitis-OTM rats, STING, IL-1\u03b2 and IL-6 were upregulated and Runx-2 downregulated on the compression side, leading to increased alveolar bone loss that was rescued by H151. Under mechanical-inflammatory stress, activated STING triggered ER stress, and a cascade of cellular responses including increased pro-inflammatory mediators, enhanced apoptosis, altered mechano-response, and suppressed osteogenesis. Meanwhile, Annexin A2 (Anxa2) was identified as a novel STING interactor. Anxa2 knockdown mirrored STING inhibition, suppressing ER stress, inflammatory activation, apoptosis and mechano-response. Mechanistically, Anxa2 knockdown markedly reduced P65 phosphorylation and nuclear translocation, suggesting Anxa2 may serve as an intermediary linking STING to NF-\u03baB activation. STING-Anxa2 interaction was notably increased in PDLFs and in compression-side periodontal tissues under mechanical-inflammatory stress. Within an inflammatory milieu, STING activation in PDLFs is associated with ER stress, pro-inflammatory responses, apoptosis, and suppressed osteogenesis that collectively accelerate bone resorption during OTM. We identified Annexin A2 (Anxa2) as a novel STING interactor whose knockdown attenuated these responses and NF-\u03baB activation, suggesting Anxa2 as a functional intermediary in STING-mediated inflammation.\n\nID: 42468665\nTitle: Is Urolithin A(UA) a Pharmacologically Credible Neuro-Nutraceutical? A Critical Review of Mechanisms, Brain Exposure, and Evidence Gaps in Alzheimer's and Parkinson's Disease.\nAbstract: Urolithin A(UA) is a gut microbiota-derived metabolite of dietary ellagitannins and ellagic acid, generated by specific gut bacterial species and absent from food in free form. Preclinical evidence indicates that UA restores PINK1/Parkin-mediated mitophagy, attenuates NF-\u03baB, NLRP3 inflammasome and cGAS-STING-driven neuroinflammation, and preserves synaptic and cognitive function across rodent and cell-culture models of Alzheimer's disease, Parkinson's disease, and age-related cognitive decline. However, circulating UA in humans exists predominantly as phase II glucuronide and sulfate conjugates rather than free aglycone, and human clinical evidence to date establishes UA's safety, favorable pharmacokinetics, mitochondrial target engagement, and benefits to muscle strength and physical function in middle-aged and older adults, with no completed trial yet evaluating cognitive or neurodegenerative disease-modifying outcomes. This review critically examines whether UA's neuroprotective mechanisms are pathway-specific and supported by convergent preclinical and human data, while explicitly separating mechanistic plausibility from demonstrated clinical efficacy.UA therefore represents a promising but still investigational neuro-nutraceutical candidate, with a mechanistic foundation strong enough to justify dedicated, CNS-endpoint-focused clinical trials as the next logical step toward establishing its neuroprotective potential in humans.\n\nID: 42467855\nTitle: HD-tDCS Restores Perivascular AQP4 Polarization via PPAR\u03b3 Modulation to Enhance Glymphatic Clearance After Intracerebral Hemorrhage in Mice.\nAbstract: Impaired perivascular aquaporin 4 (AQP4) polarization and glymphatic dysfunction after intracerebral hemorrhage (ICH) may delay hematoma and perihematomal edema resolution. The effects of high-definition transcranial direct current stimulation (HD-tDCS) on glymphatic transport and recovery after ICH, as well as the underlying mechanisms, are investigated in a collagenase-induced mouse model. HD-tDCS (anodal stimulation, 0.1\u00a0mA, 10\u00a0min daily) significantly enhances cerebrospinal fluid influx, improves interstitial solute clearance, reduces intracerebral tracer retention, and increases drainage to the deep cervical lymph nodes, as assessed by in vivo two-photon imaging, contrast-enhanced MRI, and ex vivo tracer analysis. HD-tDCS also accelerates hematoma and edema resolution, reduces midline shift and diffusion abnormalities, and improves neurological outcomes. Mechanistically, ICH induces astrocytic proinflammatory activation together with impaired perivascular AQP4 polarization, whereas HD-tDCS upregulates peroxisome proliferator-activated receptor gamma (PPAR\u03b3), suppresses proinflammatory astrocyte activation, and restores perivascular AQP4 localization. Astrocyte-specific knockdown or pharmacologic inhibition of PPAR\u03b3 attenuates HD-tDCS-induced AQP4 repolarization, glymphatic recovery, and neurological improvement. These findings indicate that HD-tDCS promotes hematoma and edema resolution after ICH in association with PPAR\u03b3-dependent astrocyte remodeling, AQP4 repolarization, and glymphatic restoration.\n\nID: 42465772\nTitle: Molecular signaling in coinfection: how M. tuberculosis and respiratory viruses rewire host immunity and alter TB outcomes.\nAbstract: Tuberculosis (TB) caused by Mycobacterium tuberculosis (M. tuberculosis) and respiratory viral infections remain major, intersecting global health challenges, and their co-occurrence imposes a disproportionate burden in high-HIV/high-TB regions such as sub-Saharan Africa. Coinfection biology is heterogeneous and dynamic, driven by viral diversity including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza A/B, Respiratory Syncytial Virus (RSV), parainfluenza, metapneumovirus, rhinovirus, adenovirus, and bocavirus, and by the underlying TB stage, from latent and subclinical to active and reactivation disease. Innate sensing pathways, such as Toll-like receptors (TLR), retinoic acid-inducible gene I (RIG-I), and cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING), converge during coinfection, reshaping type I interferon (IFN-I), Nuclear Factor kappa-light-chain-enhancer of activated B cells (NF-\u03baB), and AP-1-driven responses and triggering a network of autocrine and paracrine signaling that reprograms macrophages, dendritic cells, and T-cell subsets. This immune rewiring alters granuloma equilibrium through suppressed Th1/IFN-\u03b3 coordination, exaggerated Th17/IL-17-driven neutrophilia, and regulatory T-cell or IL-10-mediated dampening, which together destabilize macrophage activation and tissue architecture. Oxidative stress, mitochondrial dysfunction, and Matrix Metalloproteinases (MMP)-driven matrix remodeling further integrate with these pathways, converting inflammatory signals into epithelial damage, cavitation, and fibrosis. Consequently, disease outcomes depend critically on timing, viral burden, pathogen order, host immune endotype, and TB stage, such that the same virus can either preserve containment or drive progression depending on the local immunological context. Importantly, the effects of respiratory viral coinfection vary across the TB disease continuum, influencing early granuloma formation, latent infection, reactivation risk, and established disease through distinct immunological mechanisms. Host-directed therapies (HDT) targeting interferon, IL-1, TNF, inflammasome, or metabolic checkpoints hold mechanistic promise but exhibit variable clinical translation, underscoring the need for precision approaches that integrate stage- and endotype-specific biomarkers. This narrative review proposes an integrated systems framework that links viral sensing, immune rewiring, granuloma biology, and tissue-remodeling to TB-respiratory virus coinfection, and emphasizes how timing-aware, biomarker-guided strategies can refine diagnosis, clinical management, prognosis, and vaccine design in vulnerable populations.\n\nID: 42465768\nTitle: Gut-lung axis in radiation-induced lung injury: mechanisms and interventions.\nAbstract: Radiation-induced lung injury (RILI) constrains thoracic radiotherapy dosing and includes acute radiation pneumonitis (RP) and chronic radiation-induced pulmonary fibrosis (RPF). This narrative review explores the gut-lung microbiota axis in RILI, synthesizing evidence from preclinical models, clinical cohorts (N\u00a0=\u00a052-89), and randomized controlled trials (RCTs). Radiotherapy induces gut dysbiosis, barrier breakdown, and metabolite changes [e.g., short-chain fatty acid (SCFA) and desaminotyrosine (DAT) depletion], promoting inflammation and fibrosis via pathways such as Toll-like receptor 4/nuclear factor kappa B (TLR4/NF-\u03baB), TGF-\u03b2/Smad, sphingosine-1-phosphate (S1P)-S1PR, and cGAS-STING in animal studies. Inter-species microbial variations hinder translation, while lung microbiota shifts remain nascent. In non-small cell lung cancer cohorts, lower gut microbiota stability (a marker of dysbiosis) is associated with an increased risk of grade \u22652 RP (multivariable-adjusted models, p < 0.05), with higher baseline Faecalibacterium abundance conferring protection; however, causality remains unproven due to antibiotic confounding. Mechanisms involve lipopolysaccharide (LPS) translocation, interleukin 25 (IL-25)/S1P-driven type 2 innate lymphoid cell (ILC2) migration, regulatory T cell/T helper 17 cell (Treg/Th17) imbalance, and extracellular vesicle (EV) signaling, with biomarkers such as 16S rRNA sequencing and EV-miRNAs (e.g., miR-486-5p). Artificial intelligence models predict RP with 75% accuracy. Phase-specific interventions, such as pre-radiotherapy gut microbiota monitoring, intra-radiotherapy SCFA supplementation, subacute DAT modulation, and RPF-targeted EV therapies, have been explored in preliminary pilot studies [for example, one small study reported approximately 12% FEV1 improvement following fecal microbiota transplantation (FMT)]. Future large-scale, stratified RCTs that properly account for antibiotics, chemotherapy, and immunotherapy are required to establish causality beyond the current largely associative clinical evidence. The integration of immunotherapy and proton therapy in such trials may help clarify gut-lung interactions, including any microbiota-preserving effects of proton therapy; the role of the lung microbiota in fibrosis remains preliminary.\n\nID: 42463065\nTitle: Mitochondrial dynamics and metabolic regulation in cellular inflammation: From mechanisms to precision therapeutics.\nAbstract: Beyond their canonical role in bioenergetics, mitochondria are now recognized as critical signaling platforms that orchestrate innate immune responses. Central to this function is mitochondrial dynamics-the controlled equilibrium between fission and fusion-which serves as a critical structural and thermodynamic checkpoint for cellular fate and immunological status. A substantial body of evidence indicates that pathological mitochondrial fission, frequently driven by Dynamin-related protein 1 (Drp1), is a hallmark of numerous inflammatory conditions. Mechanistically, fragmented mitochondria release damage-associated molecular patterns (DAMPs) and induce acute ATP suppression, metabolically \"licensing\" NLRP3 activation by collapsing the ATP hydrolysis potential (\u0394GATP). Recent breakthroughs have redefined this axis, distinguishing between physical damage and metabolic triggers, such as pyrimidine imbalance via the YME1L-SLC25A33 axis. Furthermore, the immunogenicity of DAMPs is strictly context-dependent; oxidized or \"fragile\" mtDNA containing ribonucleotides act as hyper-immunogenic ligands for cytosolic sensors like cGAS-STING. Emerging evidence further highlights that endosomal-mitochondrial crosstalk, intercellular mitochondrial transfer, and lipid-driven metabolic rewiring profoundly govern macrophage polarization and tissue homeostasis. Conversely, promoting mitochondrial fusion and robust quality control preserves organellar integrity and attenuates inflammatory cascades. This review critically synthesizes current literature, deconstructing the molecular linkages between organelle structure and metabolic signaling. By exploring the consequences in sepsis, neuroinflammation, osteoarthritis, and cancer, this treatise evaluates the pharmacological potential of modulating mitochondrial dynamics-ranging from direct Drp1 inhibitors and unfractionated heparin to metabolic stabilizers (e.g., GLP-1 receptor agonists), multi-pronged disruptors (e.g., Antimycin A), targeted nanomedicine, and communication-driven mitochondrial transplantation-positioning this axis as a promising frontier for precision pharmacology.\n\nID: 42462870\nTitle: LKB1/ AMPK deficiency aggravates mitochondrial DNA leakage via mTOR-dependent mitophagy damage in liver injury sensitized by trichloroethylene.\nAbstract: Occupational medicamentosa-like dermatitis induced by trichloroethylene (OMDT) is a severe systemic allergic disease, often accompanied by acute liver injury. However, the underlying mechanisms linking metabolic disorders and immune damage remain unclear. In a TCE-sensitized mouse model, we demonstrated that TCE sensitization inhibited LKB1/AMPK/mTOR signaling pathway (LKB1 overexpression, AICAR, rapamycin) or autophagy (3-MA) in hepatocytes, resulting in defective mitophagy. This mitochondrial dysfunction leads to leakage of mitochondrial DNA (mtDNA) into the cytoplasm, where mtDNA acts as a damage-associated molecular pattern (DAMP) to activate the cGAS-STING pathway, driving the production of proinflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and exacerbating liver inflammation. Restoration of LKB1/AMPK signaling or inhibition of mTOR rescued mitophagi, reduced mitochondrial DNA leakage, inhibited cGAS-STING activation, and alleviated liver pathology, while inhibition of autophagy alone recapitulated the TCE-induced phenotype. Taken together, our findings demonstrate that failure of TCE via LKB1/AMPK/mTOR mediated mitophagy destroys hepatocyte homeostasis, leading to mtDNA-driven cGAS-STING activation and immune-mediated liver injury in the pathogenesis of OMDT, thus providing a potential therapeutic target for OMDT-related liver injury.\n\nID: 42459658\nTitle: The mitochondrial logic of inflammaging: how energy imbalance drives fibroblast SASP and tissue-specific aging.\nAbstract: The conversion of metabolic disequilibrium into chronic inflammatory signaling represents a central and actively investigated question in ageing biology. Among stromal cells, fibroblasts are key effectors of tissue remodeling and inflammation, acquiring a senescence-associated secretory phenotype (SASP) that sustains age-related pathology. Here, we delineate a mechanistic framework in which disruption of energy homeostasis drives mitochondrial dysfunction, innate immune activation, and SASP secretion. Mitochondria act as metabolic sentinels that sense energetic stress through altered AMP/ATP and NAD+/NADH ratios, leading to the generation of mitochondrial danger signals-reactive oxygen species (mtROS) and mitochondrial DNA (mtDNA). These signals converge on canonical immune pathways, including the cGAS-STING axis, NLRP3 inflammasome, and NF-\u03baB signaling, thereby converting metabolic distress into persistent pro-inflammatory output. Using periodontal ligament fibroblasts as a disease-relevant model, we highlight how microbial biofilm exposure induces mitochondrial metabolic reprogramming that amplifies fibroblast SASP, promotes osteoclastogenesis, extracellular-matrix degradation, and alveolar bone resorption. At the transcriptional level, regulatory networks involving NF-\u03baB, C/EBP\u03b2, STATs, and the mTOR-AMPK hub integrate mitochondrial signals to sustain inflammatory senescence. We propose that restoring mitochondrial metabolic homeostasis serves as a highly promising strategy to break the self-perpetuating cycle in which energy imbalance triggers SASP activation, which in turn contributes to chronic inflammation. Researchers must first characterize the tissue-specific mitochondrial signatures of SASP. Subsequently, developing precise, lesion-targeted metabolic interventions will open new avenues for mitigating inflammaging and rejuvenating stromal function across ageing tissues.\n\nID: 42457929\nTitle: MGMT deficiency augments STING-mediated inflammatory responses accompanied by metabolic alterations in macrophages.\nAbstract: The cGAS-STING pathway senses cytosolic DNA derived from both pathogens and host cells and plays a central role in innate immune responses. O6-methylguanine-DNA methyltransferase (MGMT) is a DNA repair enzyme that removes alkylation-induced DNA lesions and modulates macrophage inflammatory responses. Here, we investigated the role of MGMT in macrophage responses to STING activation. Bone marrow-derived macrophages (BMMs) from Lyz2\u0394Mgmt mice produced higher levels of IL6, TNF\u03b1, and IFN\u03b2 following stimulation with the STING agonist DMXAA, accompanied by increased phosphorylation of TBK1 and IRF3. Lyz2\u0394Mgmt BMMs also exhibited increased expression of CD86, CD40, and CD120a (TNFRI), but reduced MHC class II expression. Metabolic flux analysis revealed enhanced mitochondrial oxidative respiration, increased ATP production, and greater maximal respiratory capacity, whereas glycolytic capacity remained unchanged. In addition, DMXAA-stimulated Lyz2\u0394Mgmt BMMs displayed increased \u03b3H2AX levels and reduced activation of the energy sensor AMPK and autophagy. Transcriptomic analysis further identified enrichment of pathways associated with cellular respiration. Collectively, these findings indicate that MGMT deficiency is associated with enhanced STING-induced inflammatory responses, altered cellular metabolism, and increased DNA damage in macrophages.\n\nID: 42457927\nTitle: DHRS9 generates crotonyl-CoA from butyryl-CoA to epigenetically regulate STING transcription and potentiate immune activation.\nAbstract: The stimulator of interferon genes (STING) pathway is a cornerstone of innate immunity and a promising therapeutic target for autoimmune diseases, inflammation, and cancer treatment. Lysine crotonylation, a recently discovered post-translational modification, regulates various cellular processes; however, its role in STING activation remains unclear. Here, we identified dehydrogenase/reductase (SDR family) member 9 (DHRS9) as a critical metabolic regulator of the STING signaling pathway. DHRS9 deficiency impaired activation of the\u00a0cGAS-STING pathway, suppressed antiviral immunity against HSV-1, and exacerbated viral replication. Mechanistically, DHRS9 converts butyryl-CoA into crotonyl-CoA, thereby enhancing histone crotonylation (H3K14cr and H3K18cr) at the STING promoter to drive its transcription. AAV-mediated DHRS9 delivery significantly enhances antiviral and antitumor immunity, demonstrating its robust therapeutic potential. This study reveals a metabolic-epigenetic axis that regulates STING expression, offering new therapeutic strategies for immune-related diseases.\n\nID: 42457332\nTitle: [Thymosin \u03b24 inhibits pyroptosis in BV2 microglial cells: a mechanistic study in vitro].\nAbstract: To investigate the protective effects and molecular mechanisms of thymosin \u03b24 (T\u03b24) on pyroptosis in BV2 microglial cells. BV2 cells were divided into three groups: control group (no treatment), pyroptosis group [stimulated with 1 \u03bcg/mL lipopolysaccharide (LPS) for 12 hours, followed by 10 \u03bcmol/L nigericin (Nig) treatment for 1 hour], and T\u03b24 treatment group (co-incubated with LPS and Nig, then treated with 1 \u03bcg/mL T\u03b24 for 1 hour). An in vitro sepsis-associated encephalopathy model was established by LPS and Nig co-treatment. Viability of BV2 cells was assessed by CCK-8 assay. RT-qPCR was performed to detect mRNA expression of interleukin (IL)-1\u03b2, interferon-induced protein with tetratricopeptide repeats 1 (IFIT1), and interferon-\u03b2 (IFN-\u03b2). IL-1\u03b2 levels in cell supernatants were measured by ELISA. Protein expression of NLRP3, GSDMD-N, cleaved caspase-1, phosphorylated stimulator of interferon genes (p-STING), and phosphorylated interferon regulatory factor 3 (p-IRF3) was analyzed by Western blot. Cell death rate and mitochondrial reactive oxygen species (ROS) levels were detected by flow cytometry using propidium iodide staining and MitoSOX indicator, respectively. Compared with the pyroptosis group, T\u03b24 treatment alleviated morphological damage caused by pyroptosis in BV2 cells. Intracellular mRNA expression of IL-1\u03b2, IFIT1, and IFN-\u03b2; IL-1\u03b2 concentration in supernatant; protein expression of NLRP3, GSDMD-N, cleaved caspase-1, p-STING, and p-IRF3; cell death rate; and mitochondrial ROS levels were significantly decreased (P0.05). T\u03b24 protects BV2 microglial cells against LPS and Nig-induced pyroptosis by inhibiting oxidative stress and inflammatory responses, potentially through regulation of the cGAS-STING signaling pathway. \u76ee\u7684: \u63a2\u7a76\u80f8\u817a\u7d20\u03b24\uff08thymosin beta 4, T\u03b24\uff09\u5bf9BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\u7126\u4ea1\u7684\u4fdd\u62a4\u4f5c\u7528\u53ca\u5206\u5b50\u673a\u5236\u3002\u65b9\u6cd5: \u5c06BV2\u7ec6\u80de\u5206\u4e3a\u5bf9\u7167\u7ec4\uff08\u4e0d\u4f5c\u4efb\u4f55\u5904\u7406\uff09\u3001\u7126\u4ea1\u7ec4[1 \u03bcg/mL\u8102\u591a\u7cd6\uff08lipopolysaccharide, LPS\uff09\u523a\u6fc012 h\u540e\uff0c\u7ed9\u4e8810 \u03bcmol/L\u5c3c\u65e5\u5229\u4e9a\u83cc\u7d20\uff08Nigericin, Nig\uff09\u5904\u74061 h]\u3001T\u03b24\u5904\u7406\u7ec4\uff08\u540c\u6b65\u7ed9\u4e88LPS\u3001Nig\u540e\uff0c1 \u03bcg/mL T\u03b24\u5904\u74061 h\uff09\u3002\u901a\u8fc7LPS\u8054\u5408Nig\u5904\u7406BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\uff0c\u6784\u5efa\u8113\u6bd2\u75c7\u76f8\u5173\u6027\u8111\u75c5\u4f53\u5916\u6a21\u578b\u3002\u91c7\u7528CCK\u20118\u6cd5\u68c0\u6d4bT\u03b24\u5bf9BV2\u7ec6\u80de\u7684\u7ec6\u80de\u6d3b\u529b\uff0c\u53cd\u8f6c\u5f55\u5b9e\u65f6\u8367\u5149\u5b9a\u91cfPCR\u6cd5\u68c0\u6d4b\u767d\u7ec6\u80de\u4ecb\u7d20\uff08interleukin, IL\uff09\u20111\u03b2\u3001\u5e72\u6270\u7d20\u8bf1\u5bfc\u86cb\u767d\u56db\u80bd\u91cd\u590d\u5e8f\u52171\u3001\u03b2\u5e72\u6270\u7d20mRNA\u8868\u8fbe\u6c34\u5e73\uff0c\u9176\u8054\u514d\u75ab\u5438\u9644\u8bd5\u9a8c\u68c0\u6d4b\u7ec6\u80de\u4e0a\u6e05\u6db2\u4e2dIL\u20111\u03b2\u6c34\u5e73\uff0cWestern blot\u6cd5\u68c0\u6d4bNOD\u6837\u53d7\u4f53\u70ed\u86cb\u767d\u7ed3\u6784\u57df\u76f8\u5173\u86cb\u767d3\u3001\u6d88\u76ae\u7d20D N\u7aef\u7247\u6bb5\u3001\u5207\u5272\u578b\u80f1\u5929\u86cb\u767d\u91761\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u57fa\u56e0\u523a\u6fc0\u56e0\u5b50\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u8c03\u8282\u56e0\u5b503\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff0c\u6d41\u5f0f\u7ec6\u80de\u672f\u7ed3\u5408\u7898\u5316\u4e19\u5576\u67d3\u8272\u68c0\u6d4b\u7ec6\u80de\u6b7b\u4ea1\u7387\uff0cMitoSOX\u8367\u5149\u6307\u793a\u5242\u68c0\u6d4b\u7ec6\u80de\u7ebf\u7c92\u4f53\u6d3b\u6027\u6c27\u6c34\u5e73\u3002\u7ed3\u679c: \u4e0e\u7126\u4ea1\u6a21\u578b\u7ec4\u6bd4\u8f83\uff0cT\u03b24\u5904\u7406\u7ec4BV2\u7ec6\u80de\u7126\u4ea1\u5f62\u6001\u635f\u4f24\u51cf\u8f7b\uff0c\u7ec6\u80de\u5185IL\u20111\u03b2\u3001\u5e72\u6270\u7d20\u8bf1\u5bfc\u86cb\u767d\u56db\u80bd\u91cd\u590d\u5e8f\u52171\u3001\u03b2\u5e72\u6270\u7d20mRNA\u8868\u8fbe\u4e0e\u7ec6\u80de\u4e0a\u6e05IL\u20111\u03b2\u542b\u91cf\u3001NOD\u6837\u53d7\u4f53\u70ed\u86cb\u767d\u7ed3\u6784\u57df\u76f8\u5173\u86cb\u767d3\u3001\u6d88\u76ae\u7d20D N\u7aef\u7247\u6bb5\u3001\u5207\u5272\u578b\u80f1\u5929\u86cb\u767d\u91761\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u57fa\u56e0\u523a\u6fc0\u56e0\u5b50\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u8c03\u8282\u56e0\u5b503\u86cb\u767d\u8868\u8fbe\u53ca\u7ec6\u80de\u6b7b\u4ea1\u7387\u3001\u7ebf\u7c92\u4f53\u6d3b\u6027\u6c27\u6c34\u5e73\u964d\u4f4e\uff08P0.05\uff09\u3002\u7ed3\u8bba: T\u03b24\u53ef\u6539\u5584LPS+Nig\u8bf1\u5bfc\u7684BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\u7126\u4ea1\u635f\u4f24\uff0c\u6291\u5236\u6c27\u5316\u5e94\u6fc0\u4e0e\u708e\u75c7\u53cd\u5e94\uff0c\u5176\u673a\u5236\u53ef\u80fd\u4e0ecGAS\u2011STING\u4fe1\u53f7\u901a\u8def\u6709\u5173\u3002.\n\nID: 42456532\nTitle: Ring-finger protein 5 protects against diabetic kidney disease by targeting and degrading STING.\nAbstract: The stimulator of interferon genes (STING) has been recognized as a pivotal modulator in the pathological progression of diabetic kidney disease (DKD). Ring-finger protein 5 (RNF5) is an important modulator of STING and is implicated in various disease processes. Nevertheless, the function of RNF5/STING axis in the context of DKD has yet to be investigated. This research was undertaken to explore whether RNF5 regulates the progression of DKD through modulation of the STING pathway, as well as to clarify the mechanisms involved. We found that RNF5 levels were significantly reduced in high glucose (HG)-stimulated HK-2 cells and the kidneys of diabetic mice. Upregulation of RNF5 inhibited HG-induced cellular injury, fibrosis, and inflammatory responses, while RNF5 knockdown exacerbated these detrimental effects. Moreover, HG treatment led to increased levels of STING, phosphorylated TBK1, phosphorylated IRF-3, and phosphorylated NF-\u03baB, indicating STING pathway activation. RNF5 overexpression significantly suppressed the activation of the STING pathway induced by HG, whereas RNF5 knockdown enhanced it. Mechanistically, RNF5 promoted the ubiquitination and degradation of STING. Inhibition of STING abolished the exacerbating effect of RNF5 knockdown on HG-induced cellular injury. Animal studies revealed that RNF5 overexpression alleviated kidney damage, fibrosis, and inflammation in diabetic mouse models, concomitantly suppressing STING pathway activation. Collectively, RNF5 inhibits HG-induced tubular cell injury by promoting STING degradation, thereby suppressing STING pathway activation. Targeting RNF5 could be a potentially effective therapeutic approach for DKD.\n\nID: 42455155\nTitle: Evaluation of Glymphatic System Activity in Pediatric Wilson Disease Patients Using Diffusion Tensor Imaging Along the Perivascular Space.\nAbstract: Wilson disease is an autosomal recessive disorder of copper metabolism that results in toxic copper accumulation in the liver and brain, thereby causing neurological injury. Previous reports have described astrocyte dysfunction, oxidative stress, glial pathology, and impaired aquaporin-4-mediated water transport in Wilson disease, suggesting a\u00a0potential disruption of glymphatic fluid dynamics. However, glymphatic function has not been quantitatively assessed in this population using diffusion tensor imaging analysis along the perivascular space (DTI-ALPS). This retrospective single-center study aimed to quantify glymphatic system function in pediatric patients with Wilson disease using the DTI-ALPS index. Brain MRI/DTI data (30\u00a0directions, b\u202f=\u20091000\u202fs/mm2) from 43\u00a0patients younger than 18\u00a0years diagnosed according to the Leipzig criteria (2018-2025) were analyzed and compared with 43 age- and sex-matched healthy controls. Neuro-Wilson status was defined by MRI involvement plus neurological symptoms. ALPS indices were derived from regions of interest in the corona radiata and superior longitudinal fasciculus on color-FA maps. The analyses included group comparisons, correlations with clinical variables, and a\u00a0secondary sensitivity ANCOVA adjusted for age and sex to confirm the robustness of group differences despite demographic matching. Right-, left-, and mean ALPS indices were significantly lower in patients with Wilson's disease than in controls, with this group effect persisting after demographic adjustment (F\u202f=\u200913.90, p\u202f<\u20090.001; adjusted means: controls 1.51, WD 1.34, NWD 1.38). ALPS indices did not differ between the WD and NWD subgroups despite higher liver severity scores in the latter. ALPS values did not correlate with liver severity scores, urinary copper, ceruloplasmin or sex. These findings suggest that the DTI-ALPS index may reflect glymphatic system-related processes, as well as disease-related microstructural and perivascular alterations, in pediatric Wilson disease. The DTI-ALPS index may provide complementary, non-invasive imaging information regarding early perivascular microstructural alterations. Prospective multicenter longitudinal studies are warranted to clarify the temporal relationships among ALPS index changes, neurological progression, and treatment response.\n\nID: 42450183\nTitle: Mitochondrial Immunometabolism in Sepsis: From Oxidative Stress and mtDAMP Signaling to Biomarker-Guided Therapy.\nAbstract: Sepsis is a life-threatening syndrome characterized by a dysregulated host response to infection and progressive organ dysfunction. Although early antimicrobial therapy, source control, hemodynamic resuscitation, and organ support remain the foundations of care, these approaches do not directly reverse the cellular mechanisms that connect systemic inflammation to multi-organ failure. Mitochondrial dysfunction has emerged as a central mechanism linking impaired oxygen utilization, oxidative and nitrosative stress, immune-cell metabolic reprogramming, inflammatory amplification, and organ injury. During sepsis, inflammatory mediators, nitric oxide, microcirculatory abnormalities, calcium dysregulation, and metabolic stress converge on mitochondria, impairing oxidative phosphorylation and promoting mitochondrial reactive oxygen species/reactive nitrogen species (ROS/RNS) generation. When mitochondrial quality-control programs, including fission, fusion, mitophagy, and mitochondrial biogenesis, fail to restore network integrity, damaged mitochondria accumulate and become persistent sources of oxidative stress and danger signals. Mitochondrial damage-associated molecular patterns, particularly mitochondrial DNA, oxidized mitochondrial DNA, cardiolipin, ATP, and N-formyl peptides, activate innate immune pathways such as TLR9-MyD88-NF-kappaB, the NLRP3 inflammasome, and cGAS-STING signaling. In parallel, mitochondrial metabolism shapes macrophage activation, neutrophil function, T-cell competence, pyruvate-lactate handling through the pyruvate dehydrogenase complex, and the transition between hyperinflammation and immunosuppression. Clinical translation remains challenging because sepsis is biologically heterogeneous and mitochondrial dysfunction is dynamic, tissue-specific, and influenced by disease stage. This review synthesizes current knowledge on mitochondrial dysfunction in sepsis, emphasizing oxidative and nitrosative stress, mitochondrial quality control, mitochondrial damage-associated molecular pattern (DAMP) signaling, immunometabolism, organ-specific injury, candidate biomarkers, clinical translational strategies for mitochondria-targeted therapy, and future approaches based on multi-omics and artificial intelligence-assisted patient stratification. We argue that future therapeutic development should move beyond nonspecific antioxidant supplementation toward time-sensitive, phenotype-informed, and biomarker-guided mitochondrial medicine.\n\nID: 42449613\nTitle: Tumor Treating Fields and the Glioblastoma Microenvironment: Mechanistic Convergences with Radiotherapy.\nAbstract: Glioblastoma (GBM) remains the most lethal primary brain tumor in adults, with a median overall survival of approximately 15-20 months despite multimodal treatment including surgery, chemoradiation, and Tumor Treating Fields (TTFields). While the survival benefit of TTFields was established by the EF-14 phase III trial, their biological effects extend well beyond the canonical anti-mitotic mechanism and encompass extensive interactions with the GBM tumor microenvironment (TME). This review provides an integrated mechanistic analysis of TTFields-TME interactions in GBM, with a distinctive focus on their convergence with radiotherapy. We examine how TTFields activate innate immune sensing through cGAS/STING and AIM2 inflammasome pathways, drive immunogenic cell death, reprogram tumor-associated macrophages, and prime adaptive T cell responses. We further address TTFields effects on glioma stem cells, blood-brain barrier permeability, and intracellular signaling governing invasion, angiogenesis, and autophagy. Critically, we develop the mechanistic and clinical case for TTFields-radiotherapy combinations, highlighting convergent mechanisms of DNA repair impairment, mitotic catastrophe, and innate immune activation. Practical considerations for concurrent clinical implementation are discussed alongside a research agenda centered on optimal timing, hypofractionation, and predictive biomarkers. Available evidence-largely preclinical-suggests that TTFields may act as a TME-remodeling platform whose potential is most likely to be realized through mechanistically informed combinations.\n\nID: 42444292\nTitle: Discovery of a novel STING-binding peptide associated with reduced cGAMP-induced inflammatory gene expression.\nAbstract: cGAMP-induced STING activation contributes to inflammatory and interferon-related signalling, making STING a relevant target for inhibitor development. In this study, a 59,319-sequence peptide library was screened against STING by molecular docking, and four top-ranked peptides were selected for evaluation. MST analysis demonstrated that Peptides 1-4 bound to recombinant STING, with Peptide-1 showing the highest affinity (Kd = 0.15\u2009\u00b1\u20090.01\u2009\u03bcM). Docking and simulation analyses suggested that binding was mediated by hydrogen bonding and hydrophobic contacts. Molecular dynamics, MM/PBSA, and free energy landscape analyses suggested stable binding with favourable calculated energetics. Peptide-1 showed no apparent cytotoxicity up to 10\u2009\u03bcM in RAW264.7 macrophages and primary BMDMs, while dose-dependently reducing cGAMP-induced IFN-\u03b2 and IL-6 expression at both protein and mRNA levels. This inhibitory effect was accompanied by reduced STING and IRF3 phosphorylation. Collectively, these findings suggest that Peptide-1 may bind STING and attenuate cGAMP-induced IFN-\u03b2 and IL-6 expression.\n\nID: 42442517\nTitle: Navigating the cGAS-STING signaling pathway in breast cancer: Reinterpreting the paradox of antitumor and pro-metastatic.\nAbstract: The cGAS-STING signaling pathway exhibits functions in breast cancer that include both antitumor immunity and pro-metastatic inflammation, transcending traditional linear switch models. To address this cognitive bottleneck, this paper proposes the conceptual framework of \"cGAS-STING pathway-guided signal flow.\" It attributes pathway outcomes to multi-level fine-tuning, aiming to decipher initial immunogenic/pathogenic signals in the upstream phase based on intensity, duration, and origin. It elucidates how the STING protein, as a central hub, integrates and programs signals through a complex network of post-translational modifications at the midstream, thereby determining whether downstream effector branching favors the IFN-I-mediated antitumor axis or the NF-\u03baB-driven pro-metastatic inflammatory axis. Based on this framework, this paper examines the key checkpoints at each level to explore in depth how to precisely regulate the cGAS-STING signaling pathway in order to maximize antitumor immune responses while mitigating potential risks of metastasis. This navigational framework clarifies signal branching mechanisms between the IFN-I antitumor axis and the NF-\u03baB metastasis-promoting axis in breast cancer, identifies key nodes in signal branching, and evaluates the STING regulatory characteristics of various molecular subtypes. This provides both theoretical and practical foundations for signal reprogramming interventions, patient stratification, and the optimization of combination therapies.\n\nID: 42440746\nTitle: Mitochondrial DNA efflux as a potential amplifier of systemic inflammatory network rewiring in heart failure with preserved ejection fraction.\nAbstract: Heart failure with preserved ejection fraction (HFpEF) is a systemic inflammatory disease that affects multiple organs. However, the integration of different comorbid stress factors into a persistent and organ-specific inflammatory network remains unclear. Under the background of HFpEF, mitochondrial DNA (mtDNA) may not only play a role as a damage-associated molecular pattern (DAMP), but also act as a cross-organ inflammatory signal, linking the comorbid-driven mitochondrial stress with endothelial dysfunction, myocardial remodeling, and extracardiac organ involvement. Under the influence of HFpEF-related stress factors, including aging, obesity, diabetes, hypertension, and renal dysfunction, mtDNA may undergo oxidation and structural remodeling and be released in the form of free DNA, extracellular vesicle (EV)-related DNA, or neutrophil extracellular trap-related DNA. These mtDNA signals may activate the nucleic acid sensing pathways mediated by TLR9 and cGAS-STING, and promote the activation of downstream NLRP3 inflammasomes in endothelial cells, cardiomyocytes, fibroblasts, immune cells, and extracardiac tissues, thereby promoting IL-6/TNF production, type I interferon signaling, inflammasome activation, and self-amplifying inflammatory circuits related to the progression of HFpEF. Within this framework, HFpEF can be understood as a cross-organ network reconfiguration state, where mtDNA-related inflammatory signals may lead to abnormal information flow, especially in the internal phenotype characterized by metabolic stress, age-related mitochondrial damage, renal dysfunction, and systemic inflammation. The coupling between mtDNA generation, transmission, and decoding may amplify endothelial dysfunction, myocardial stiffness, fibrosis, and phenotypic-specific inflammatory remodeling; however, these processes occur within a broader pathological biology background of HFpEF, which also includes mechanisms independent of mtDNA, such as impaired NO-cGMP-PKG signaling, low phosphorylation of myosin, vascular stiffness, renal dysfunction, neurohumoral activation, and extracellular matrix remodeling. Therefore, this article proposes that mtDNA efflux is an inflammation amplifier that depends on the phenotype and disease stage, rather than being a universal or unique mechanism for explaining all HFpEF phenotypes. The existing evidence does not yet prove that mtDNA efflux is the main causal driver of HFpEF; instead, its position in the temporal sequence and causal relationship still needs to be verified in longitudinal studies and intervention studies specific to HFpEF.\n\nID: 42438675\nTitle: Dietary riboflavin blocks the cGAS-STING pathway to curb hypoxia-induced hepatic inflammation in sub-adult grass carp (Ctenopharyngodon idella).\nAbstract: This study evaluated the effect of riboflavin (VB2) on growth performance and its ability to alleviate hypoxia-induced hepatic inflammation in sub-adult grass carp (Ctenopharyngodon idella), as well as the underlying mechanisms. A total of 450 grass carp (402.16 \u00b1 1.01 g) were randomly distributed into 18 tanks and fed one of six experimental diets with varying VB2 concentrations (0.47, 1.96, 3.45, 4.97, 6.47, and 7.98 mg/kg) for 60 d, followed by a 96 h hypoxia stress experiment. The experimental results showed that, compared with VB2 deficiency (0.47 mg/kg VB2) group, the 1.96 to 7.98 mg/kg VB2 groups enhanced the percent weight gain, specific growth rate, and feed efficiency, and exerted a growth-promoting effect on grass carp (P < 0.001). In the hypoxia group, the supplementation of VB2 (3.45-6.47 mg/kg) increased hepatic VB2 content, D-amino acid oxidase, and glutathione reductase activities (P < 0.001), thereby enhancing the function of the flavoprotein. Furthermore, the 3.45 to 6.47 mg/kg VB2 groups reduced the activities of serum aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and alkaline phosphatase (P < 0.05), thereby mitigating hepatic damage induced by hypoxia. The 3.45 to 4.97 mg/kg VB2 groups increased hepatic ATP content (P < 0.001), while reducing cytoplasmic mitochondrial DNA copy number under hypoxia stress. Compared with the VB2 deficiency group, the 4.97 mg/kg VB2 group promoted the fluorescence intensity of VDAC1, TOMM20, and OPA1 under hypoxia stress (P < 0.001), thereby improving mitochondrial structure and function. Riboflavin also mitigated hypoxia-induced hepatic inflammation. Dietary 3.45 to 7.98 mg/kg VB2 reduced the expression of pro-inflammatory factors such as il-1\u03b2, tnf-\u03b1 and ifn-1, while 3.45 to 6.47 mg/kg VB2 groups increased the expression of anti-inflammatory cytokine such as il-4, il-10, and tgf-\u03b2 (P < 0.05). Dietary 4.97 mg/kg VB2 reduced the expression of p-STING, p-TBK1, p-IRF3, and p-P65 (P < 0.05). Finally, using percent weight gain, D-amino acid oxidase (D-AAO), and alanine aminotransferase (ALT) for secondary regression analysis, VB2 requirements for sub-adult grass carp were determined to be 5.39, 5.11, and 5.49 mg/kg, respectively. Overall, this study provides a theoretical basis for the role of VB2 in alleviating hypoxia-induced hepatic inflammation and for formulating diets for sub-adult grass carp.\n\nID: 42438365\nTitle: Mitochondrial Transcription Factor A Deficiency in T Cells Leads to Activation of the Cyclic Guanosine Monophosphate-Adenosine Monophosphate Synthase/Stimulator of Interferon Genes Pathway and Production of Autoantibodies in Mice.\nAbstract: Mitochondrial transcription factor A (TFAM) is a key regulator of mitochondrial DNA transcription and replication. T cell-specific TFAM-deficient mice are immunocompromised, often succumbing to viral infection, and their T cells are unresponsive to T-cell antigen receptor (TCR) stimulation, suggesting that TFAM-mediated mitochondrial activity regulates T-cell activity, such as effector function and memory formation. In contrast to the attenuation of immune response, TFAM deficiency may also induce inflammatory responses, raising the possibility that TFAM deficiency results in inflammation-mediated autoimmune responses. Thus, besides regulating T-cell function, TFAM plays important roles in autoimmune responses. However, its role in autoimmune diseases remains uncertain. We aimed to investigate the role of TFAM in autoimmune diseases using T cell-specific TFAM-deficient mice. We detected anti-double-strand (ds) DNA antibody, and interferon alpha (IFN\u03b1) and IFN\u03b3 in the serum of TFAMfl/fl CD4Cre mice after 30 weeks of age. Mononuclear cell infiltration was observed in the kidneys. TFAM-deficient T cells exhibited leakage of mitochondrial DNA into the cytoplasm. Cytoplasmic mitochondrial DNA was associated with activation of TANK-binding kinase 1 (TBK1) and IFN regulatory factor 3 (IRF3)-the downstream molecules of the nucleic acid sensor cyclic guanosine monophosphate-adenosine monophosphate synthase/stimulator of IFN genes (cGAS/STING) machinery. mRNA expression of type I IFN genes was elevated in T cells from TFAMfl/fl CD4Cre mice. The suppressive function of Foxp3+ regulatory T (Treg) cells, which play a major role in establishment of peripheral tolerance, was reduced in the absence of TFAM. Our findings suggest that T cells in TFAM-deficient conditions may contribute to immune instability and autoimmune responses by inducing type I IFN-mediated inflammatory responses.\n\nID: 42437012\nTitle: Taurochenodeoxycholic acid alleviates MPP+/MPTP-induced neurotoxicity in vitro and in vivo by suppressing ferroptosis via TGR5/cGAS/STING signaling pathway.\nAbstract: Parkinson's disease (PD) is characterized by progressive loss of dopaminergic neurons in the substantia nigra, with ferroptosis emerging as critical pathogenic mechanisms. Recent evidence suggests that STING activation can induce neuronal ferroptosis through autophagic degradation of GPX4. Taurochenodeoxycholic acid (TCDCA), a naturally occurring bile acid, has demonstrated neuroprotective properties through activation of Takeda G protein-coupled receptor 5 (TGR5). However, whether TCDCA can improve PD by modulating the cGAS-STING-ferroptosis axis remains unexplored. We investigated the effects of TCDCA treatment on motor function, dopaminergic neuronal survival, oxidative stress markers, ferroptosis-related proteins (GPX4, SLC7A11, ACSL4), and cGAS-STING signaling components in the substantia nigra of male mice subjected to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) administration and in MPP\u207a-treated SH-SY5Y cells. Behavioral assessments demonstrated that TCDCA significantly improved motor dysfunction in both open field and pole tests. TCDCA treatment markedly increased tyrosine hydroxylase-positive neurons and reduced oxidative stress markers including malondialdehyde and ferrous iron levels while restoring superoxide dismutase activity and glutathione content in the substantia nigra. Results showed that TCDCA upregulated TGR5 expression and concurrently suppressed cGAS and STING activation in both in vivo and in vitro PD models. Importantly, TCDCA treatment significantly enhanced the expression of anti-ferroptotic proteins GPX4 and SLC7A11 while reducing pro-ferroptotic ACSL4. These neuroprotective effects were associated with TGR5 upregulation and cGAS-STING pathway suppression. Our findings demonstrate that TCDCA alleviates PD-related neurodegeneration by inhibiting cGAS-STING-mediated ferroptosis through TGR5 activation, suggesting that TCDCA holds promise as a candidate drug for the treatment of PD.\n\nID: 42435628\nTitle: cGAS/STING is associated with brain-gut-liver axis disturbance and systemic inflammation in cerebral ischemia.\nAbstract: Cerebral ischemia triggers a cascade of systemic inflammatory responses closely associated with brain-gut-liver axis disturbance, yet the underlying molecular mechanism remains incompletely understood. This study aimed to elucidate the mechanistic role of the cyclic GMP-AMP synthase/stimulator of interferon genes (cGAS/STING) signaling pathway in disrupting gut-liver axis homeostasis following cerebral ischemia. Using a middle cerebral artery occlusion (MCAO) rat model, we employed a multidisciplinary approach combining behavioral, histological, molecular, and biochemical assays. We demonstrated that MCAO-induced cerebral infarction led to significant neurological deficits and behavioral impairment. Concurrently, Western blot analysis confirmed a significant upregulation of caspase-3, STING, cGAS, and phosphorylated IRF3 in the hippocampus. Consistent with these central changes, protein levels of caspase-3, STING, cGAS, and IRF3 were also elevated in both colonic and hepatic tissues, while the expression of tight junction proteins ZO-1 and Occludin was downregulated in the colon. H&E staining and electron microscopy of MCAO colon revealed mucosal disruption, crypt atrophy, and inflammatory infiltration, accompanied by reduced and deformed microvilli with impaired tight junctions. These changes coincided with elevated IL-12 and IL-18 levels in both the colon and liver. Immunofluorescence confirmed cGAS upregulation in MCAO colon. RT-qPCR analysis demonstrated a consistent pro-inflammatory response, with significant upregulation of cGAS, STING, IL-12, and IL-18 mRNA in the colon; elevated IL-12, IL-18, IFN-\u03b3, and IL-1\u03b2 mRNA in the liver; and increased IFN-\u03b3, IL-1\u03b2, IL-18, and IL-12 mRNA in the hippocampus. Our findings suggest cerebral ischemia-induced systemic inflammation and gut-liver axis dysfunction may be associated with the activation of the cGAS/STING pathway.\n\nID: 42435486\nTitle: Metabolite-driven epigenetic modifications remodel immune cell functions in COPD: From Lactylation to Succinylation.\nAbstract: Chronic obstructive pulmonary disease (COPD) is characterized by persistent airway inflammation, progressive immune dysfunction, and irreversible structural remodeling. Although cigarette smoke-induced oxidative stress has long been recognized as the predominant pathogenic driver, conventional inflammatory theories fail to fully account for the sustained inflammatory state that persists even after smoking cessation. Accumulating evidence indicates that COPD is governed by a metabolite-centered epigenetic regulatory network. Intracellular metabolic intermediates function not only as substrates for energy metabolism, but also as signaling molecules that directly modulate chromatin architecture and transcriptional programs. In this context, metabolic reprogramming emerges as a pivotal determinant of immune cell fate and inflammatory memory formation. This review systematically summarizes recent research advances in the \"metabolite-redox-epigenetics\" axis in COPD. We specifically discuss histone lactylation as a glycolysis-dependent inflammatory amplification mechanism and propose that histone succinylation represents a redox-sensitive epigenetic mechanism linked to mitochondrial dysfunction, bridging tricarboxylic acid (TCA) cycle dysregulation and persistent immune activation. We further integrate acetylation, crotonylation, \u03b2-hydroxybutyrylation, DNA methylation, and RNA m6A modification to construct a unified immunometabolic regulatory network. We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility, which stably enforces pathogenic immune phenotypes. Targeting metabolite-driven epigenetic remodeling may offer novel therapeutic strategies to reverse chronic inflammatory memory and restore immune homeostasis. Recent evidence further suggests that cGAS-STING-mediated mitochondrial DNA sensing, inflammasome-dependent pyroptosis, gut-lung axis-derived metabolites, and AMPK/SIRT1/PGC-1\u03b1 signaling may provide additional links between metabolic stress, epithelial injury, and immune dysfunction.\n\nID: 42435423\nTitle: Targeted Degradation of STING by a Neutrophil Membrane-Coated Nanoplatform Suppresses Microglial Pyroptosis After Subarachnoid Hemorrhage.\nAbstract: Subarachnoid hemorrhage (SAH) is a life-threatening cerebrovascular disease in which neuroinflammation and neuronal death critically contribute to poor outcomes. Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH. This work establishes a novel biomimetic nanomedicine strategy for SAH therapy and opens new avenues for treating neuroinflammation-related disorders.\n\nID: 42484938\nTitle: The Clearance-Centered Bottleneck in Alzheimer's Disease: From Coupled Glymphatic-Lymphatic Circuits to Therapeutic Opportunities.\nAbstract: While anti-amyloid-beta (A\u03b2) monoclonal antibodies have achieved substantial success in reducing plaque burden, their modest clinical impact highlights an \"efficacy ceiling\" that necessitates a re-evaluation of Alzheimer's disease (AD) pathogenesis. This review proposes a shift from an amyloid-centered paradigm to a \"clearance-centered bottleneck\" framework, conceptualizing brain homeostasis as a coupled glymphatic-lymphatic circuit. We identify three critical rate-limiting nodes-entry, transit, and exit-that govern this circuit. These nodes fail through distinct mechanisms: arterial stiffening (entry), aquaporin-4 (AQP4) depolarization (transit), and cerebral amyloid angiopathy with impaired meningeal lymphatic drainage (exit). This multilevel failure creates a self-sustaining \"neuroimmune stalemate\"-a state in which trapped antigens and inflammatory mediators perpetuate glial reactivity that further degrades the very clearance infrastructure needed to resolve it. Distinct from prior reviews of glymphatic dysfunction in isolation, this review contributes four interlinked advances: an integrated glymphatic-lymphatic coupled-circuit framework; a bidirectional immune-clearance crosstalk model; a critical appraisal of imaging endpoints graded by trial-readiness; and a combination therapy roadmap. To overcome the current therapeutic plateau, we advocate for multinode interventions that combine amyloid-targeting therapies with clearance-enhancing agents, supported by a readiness-tiered imaging strategy-standardized proxies such as DTI-ALPS and PVS burden as enrichment/secondary endpoints and dynamic contrast-enhanced MRI for mechanistic proof-of-concept.\n\nID: 42484690\nTitle: Serial failure of the brain clearance continuum in Alzheimer's disease: mechanisms and therapeutic perspectives.\nAbstract: Alzheimer's disease (AD) is usually regarded as a neurodegenerative disorder defined by amyloid-\u03b2 (A\u03b2) deposition and abnormal tau accumulation. Increasing evidence suggests that reduced clearance of metabolic waste and pathological proteins from the brain also contributes to disease onset and progression. Previous studies have often considered choroid plexus (CP) function, glymphatic exchange, and meningeal lymphatic drainage as separate clearance processes. A continuous framework linking these structures and functions is still lacking. This review integrates recent clinical and experimental evidence and proposes the brain clearance continuum as an interpretative framework. It describes three interlinked functional interfaces: the upstream choroid plexus-cerebrospinal fluid (CP-CSF) inflow interface, the midstream parenchymal perivascular exchange interface, and the downstream meningeal lymphatic outflow interface. Under physiological conditions, these interfaces support CSF movement, parenchymal solute exchange, and the outward removal of metabolic waste. In AD, disrupted CSF homeostasis, impaired perivascular exchange, and obstructed meningeal lymphatic outflow may interact, leading to serial failure of the brain clearance continuum. This process is closely associated with A\u03b2/tau accumulation, vascular dysfunction, neuroinflammation, and cognitive decline. We also summarise potential therapeutic strategies directed at different clearance interfaces, whilst emphasising that most evidence remains preclinical or exploratory. The brain clearance continuum provides a systematic framework for understanding clearance failure in AD. It may also offer a theoretical basis for future mechanistic studies and therapeutic development that are stratified by clearance interface and disease stage.\n\nID: 42482103\nTitle: Caloric restriction enhances radiosensitivity of colorectal tumors through the cGAS-STING pathway activation.\nAbstract: Although radiotherapy is an important clinical option for colorectal cancer, its efficacy is limited by intrinsic tumor radioresistance and radiation-induced toxicity in surrounding normal tissues. This study investigated the radiosensitizing effects of either 7-day 30% caloric restriction (CR) or 24-hour fasting in a murine model bearing CT-26 colorectal tumor and explored the underlying mechanisms. CR and fasting pretreatment enhanced irradiation-induced tumor apoptosis, mitochondrial dysfunction, and cytosolic DNA stress, leading to activation of the cyclic GMP-AMP synthase/stimulator of interferon gene (cGAS-STING) pathway, increased infiltration of tumor killing-associated CD8\u2009+\u2009cytotoxic T lymphocytes, and modulation of macrophage polarization toward an antitumor phenotype. In addition, CR and fasting further suppressed the expression of glycolysis and lipid metabolism related proteins in the tumor microenvironment upon radiation exposure. By contrast, CR and fasting protected normal intestinal tissue from irradiation-induced damage. These findings were validated in vitro using CT-26 and normal small intestinal epithelial cells (IEC-6) cultured under medium with or without glucose. The critical role of the cGAS-STING pathway in enhancing radiosensitivity was confirmed through STING siRNA-mediated knockdown, combined with pharmacological intervention using the STING agonist MSA-2 and inhibitor H-151. In conclusion, our findings indicate that CR and fasting may increase the radiosensitivity of colorectal tumors, while reducing radiation injury to normal intestinal tissue.\n\nID: 42471719\nTitle: AQP4-dependent enhancement of glymphatic function attenuates tau pathology and neurodegeneration in PS19 mice.\nAbstract: The glymphatic system facilitates cerebrospinal fluid-interstitial fluid exchange and contributes to the clearance of pathogenic proteins from the brain. Glymphatic dysfunction has been associated with Alzheimer's disease and related tauopathies; however, whether impaired glymphatic transport causally drives tau accumulation and neurodegeneration, and whether its enhancement confers therapeutic benefit, remains unclear. Glymphatic water dynamics in PS19 tau transgenic mice were assessed using JJVCPE, a novel MRI-based approach for evaluating brain water exchange. The effect of pharmacological activation of aquaporin-4 (AQP4) with TGN-073 on glymphatic cerebrospinal fluid influx was examined in wild-type mice using dynamic contrast-enhanced MRI. Tau pathology, neurodegeneration, and cerebrospinal fluid tau levels were analyzed in PS19 mice following chronic TGN-073 treatment. AQP4-deficient PS19 mice were examined to determine target specificity. PS19 mice exhibited significant impairment of glymphatic water exchange at early disease stages, which progressively worsened with ageing. Pharmacological activation of AQP4 with TGN-073 robustly enhanced glymphatic-related tracer influx, reduced tau accumulation, neuronal loss, and gliosis, and was accompanied by increased cerebrospinal fluid tau levels. TGN-073 also restored perivascular AQP4 enrichment without significantly altering overall AQP4 abundance. Importantly, these beneficial effects were abolished in AQP4-deficient PS19 mice, demonstrating that both glymphatic enhancement and suppression of tau pathology and neurodegeneration are AQP4-dependent. Our findings support a mechanistic contribution of impaired glymphatic function to tau accumulation and neuronal vulnerability in tauopathy. Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis. These findings identify AQP4-mediated glymphatic modulation as a disease-relevant and therapeutically tractable pathway for tau-related neurodegenerative disorders.\n\nID: 42468696\nTitle: Manganese overload as a previously underappreciated trigger of cellular senescence: unraveling mechanisms and therapeutic rescue by the senolytic quercetin.\nAbstract: Manganese (Mn) is an essential trace element, but excessive Mn exposure is associated with neurotoxicity and aging-related dysfunction. Whether Mn overload promotes cellular senescence and the mechanisms involved remain insufficiently defined. Here, we investigated Mn-induced senescence-associated injury using Caenorhabditis elegans and neuron-like PC12 cells. Mn exposure shortened lifespan, impaired locomotor behavior, altered dopaminergic neuronal signals, and increased senescence-associated \u03b2-galactosidase activity in C. elegans. In PC12 cells, Mn induced senescence-associated phenotypes, including reduced viability, \u03b2-galactosidase positivity, telomere attrition, p53/p21 activation, oxidative stress, mitochondrial dysfunction, DNA damage-related alterations, inflammatory responses, and stimulator of interferon genes (STING)-related signaling. Quercetin attenuated Mn-induced oxidative, mitochondrial, inflammatory, and senescence-associated changes, while STING inhibition partially alleviated cell injury and \u03b2-galactosidase positivity. These findings suggest the involvement of STING-related signaling in Mn-induced neurotoxic injury accompanied by senescence-associated changes and suggest that this process may be pharmacologically attenuated.\n\nID: 42467313\nTitle: Disruption of macrophage migration inhibitory factor signaling induces major tumor-associated macrophage phenotypes in human M2 macrophages.\nAbstract: Tumor-associated macrophages (TAMs) primarily arise from infiltrating monocytes, yet the mechanisms guiding their differentiation remain unclear. Here, we show that human macrophages rely on autocrine macrophage migration inhibitory factor signaling to suppress p53 during M2-like transition. Disruption of this pathway led to activation of p53 and, unexpectedly, the nuclear receptor NR4A1, inducing a senescence-like state resembling interleukin (IL)-1\u03b2\u207a and IL-4 Induced 1 (IL4I1)\u207a TAM subsets observed across multiple cancers. These TAM-like macrophages exhibited a transcriptional program driven by NR4A1, similar to that induced in IL-1\u03b2\u207a TAMs by the combined action of tumor necrosis factor \u03b1 (TNF) and the cyclooxygenase-2-dependent arachidonic acid (AA) metabolite prostaglandin E2. They also upregulated the AA-selective acyl-CoA synthase ACSL4, which promoted cell survival and restrained IL-1\u03b2 release despite elevated IL1B expression. This effect was mediated through induction of the IL4I1\u207a TAM marker CD38, which drove the production of IL-10. Mechanistically, ACSL4 preserved the homeostatic function of stimulator of interferon genes (STING). Loss of ACSL4 resulted in extensive macrophage death and converted STING from a homeostatic regulator into a driver of IL-1 cytokine release. Finally, we show that the CDK4/6 inhibitor abemaciclib repolarized TAM-like macrophages toward a more inflammatory phenotype through off-target inhibition of ACSL4. Abemaciclib enhanced inflammatory signaling by modulating ectodomain shedding, increasing TNF while reducing the release of its natural antagonist, TNF receptor II. Together, these findings clarify mechanisms underlying scRNA-seq-defined TAM phenotypes, identify ACSL4 as a potential therapeutic target, and reveal how abemaciclib can promote inflammatory responses in cancer patients.\n\nID: 42463967\nTitle: In vivo multimodal PET/MRI imaging and plasma biomarkers implicate glymphatic dysfunction linking neuroinflammation to tau pathology in the early Alzheimer's disease continuum.\nAbstract: Neuroinflammation is a key factor contributing to cognitive decline in Alzheimer's disease (AD). This study aims to investigate the mechanistic associations among neuroinflammation, glymphatic dysfunction, tau pathology, and cognitive decline in AD spectrum. The study included 355 participants from the Alzheimer's Disease Neuroimaging Initiative (ADNI) and a supportive cohort of 59 individuals from Wuhan Union Hospital (WHUH). Tau pathology was quantified using 18F-AV1451 positron emission tomography (PET). Glymphatic function was estimated through diffusion tensor image analysis along the perivascular space (DTI-ALPS). Neuroinflammation was assessed via plasma glial fibrillary acidic protein (GFAP) in two cohorts and translocator protein (TSPO) PET imaging with 18F-DPA-714 in supportive cohort. Correlation analyses and mediation models were employed to evaluate the directional relationships among tau deposition, inflammation, glymphatic function, and cognition. Higher levels of inflammation were significantly associated with lower DTI-ALPS index (\u03b2 = -0.171, P\u2009=\u20090.046), which in turn was associated with higher tau burden (\u03b2\u2009=\u20090.162, P\u2009=\u20090.010). Path analysis revealed significant indirect associations linking neuroinflammation to cognitive performance through glymphatic dysfunction and tau pathology, with total indirect effects of -\u20090.165 (95% CI, -\u20090.266 to -\u20090.105) in ADNI and -\u20090.143 (95% CI, -\u20090.386 to -\u20090.013) in WHUH. These findings support a hypothesized inflammation-glymphatic-tau pathway rather than a definitive causal cascade. Our findings are consistent with a hypothesized inflammation-glymphatic-tau association in which greater neuroinflammation is linked to reduced glymphatic function and higher regional tau burden, particularly in preclinical and prodromal stages. This study obtained ethical approval from the Institutional Review Committee of Nanjing Drum Tower Hospital (ChiCTR-BRC-17011316, date:20170506; ChiCTR1900022526, date:20190415).\n\nID: 42461238\nTitle: Changed gene expression in Brodmann's area 9 in schizophrenia: support for a molecular pathology affecting membrane transporters and regulators involved in multiple neurotransmitter systems.\nAbstract: To identify changes in RNA levels in Brodmann's area 9 (BA 9) from people with schizophrenia compared to controls and to understand the contribution of those changes to the molecular pathology of the disorder. BA 9 RNA levels, measured in 81 people with schizophrenia and 70 healthy controls using the Affymetrix Human Exon 1.0\u2009ST Array, were compared using JMP Genomics 9.0. Differences in levels of RNA between diagnosis were accepted at fold changes of 1.0\u2009\u00b1\u2009\u2265 0.2 and p\u2009<\u20090.01. The potential effects of these changes in RNA were determined using the Panther Gene Ontology Classification System and Qiagen Ingenuity Pathways. Levels of 17,304 RNAs were measured in BA 9, with 47 RNA levels being altered (29 higher) in schizophrenia. These changes in RNA levels should affect water homeostasis, regulation of extracellular space volume, potassium buffering, CSF circulation, interstitial fluid resorption, waste clearance, neuroinflammation, osmosensation, cell migration, calcium signalling and transport, gap junctions and membrane transport. Changes in gene expression we report in BA 9 from people with schizophrenia are involved in important biochemical pathways that could contain new drug targets and could be involved in the molecular pathology of the disorder.\n\nID: 42460526\nTitle: The Role of the Mitochondrial Permeability Transition Pore in Chronic Pain.\nAbstract: The mitochondrial Permeability Transition Pore (mPTP) has been implicated in cell death, energy failure, and oxidative stress. Emerging evidence suggests that mPTP may also contribute to the development and maintenance of chronic pain, although evidence remains limited and the underlying mechanisms are not fully understood. This narrative review summarizes current findings from experimental and clinical chronic pain models and discusses how mPTP-mediated mitochondrial dysfunction may promote central sensitization and pain persistence through reactive oxygen species accumulation, neuroinflammation, apoptosis, and metabolic failure. Pharmacological strategies targeting mPTP and their therapeutic implications are further discussed. Finally, future perspectives are proposed, including mechanistic investigations, drug discovery, and clinical translation. This review highlights mPTP as a promising therapeutic target and provides a focused framework for future studies exploring mitochondrial mechanisms in chronic pain.\n\nID: 42460096\nTitle: Orchestrating the gut microbiota-mitochondrial-immune axis in gynecological diseases: mechanisms and dual-targeting therapeutic strategies.\nAbstract: The \"gut microbiota-mitochondria axis\" has become the core hub connecting the metabolism, immunity, and endocrine regulation of gynecological diseases. In this review, the hierarchical regulation mechanism of this axis is systematically combed: at the upstream level, intestinal short-chain fatty acids (SCFAs), bile acids (BAs), tryptophan derivatives, and other metabolites can activate AMPK/PGC-1\u03b1, FXR/TGR5, and AhR-mediated energy sensing and receptor signaling pathways; On the functional level, bacterial lipopolysaccharide-TLR4 signal and cGAS-STING/NLRP3 inflammasome pathway activated by cytoplasmic mitochondrial DNA (mtDNA) can amplify innate immune response; At the effect level, mitochondrial reactive oxygen species (ROS), mitochondrial dynamics, and PINK1/Parkin-mediated mitophagy are the common key nodes to regulate mitochondrial quality and inflammatory response. Combined with the two-way relationship between the estrobolome and steroid production, the above processes together form a self-reinforcing closed loop of \"metabolic input-immune amplification-oxidative stress/autophagy-endocrine regulation\". Based on this theoretical framework, this paper analyzes the disease-specific correlations among polycystic ovary syndrome, endometriosis, premature ovarian insufficiency, and gynecological malignancies, and puts forward a dual-targeted treatment idea with research value. The intervention plan with microbiota as the core aims to adjust the metabolite spectrum and endotoxin level; Mitochondria-centered interventions focus on restoring cell energy metabolism and apoptosis sensitivity. In addition, this review constructs a hierarchical research framework of \"microbiota-metabolomics-mitochondria\" to clarify the targeted phenotypes in the pathway, and provide guidance for subsequent clinical trial design and long-term monitoring. With the deep integration of multi-omics technology and targeted interventions, the gut microbiota-mitochondria axis is expected to become an important breakthrough in precision medical treatment of gynecological diseases and build a brand-new bridge between basic mechanism research and clinical transformation.\n\nID: 42458823\nTitle: A TREK-1/AQP4/TRPA1/BDNF Signaling Axis Is Associated With Astrocytic Volume Transients, Synaptic Plasticity, and Spatial Memory.\nAbstract: Astrocytes, known for their support roles, are emerging as active participants in synaptic plasticity and cognitive functions. Astrocytes actively regulate synaptic plasticity and memory through dynamic volume transients. Our previous research identified several key molecules, including TREK-1, TRPA1, and Best1 ion channels, as well as the gliotransmitter BDNF, as critical components of astrocytic volume transients. However, the precise mechanisms by which these volume transients influence synaptic plasticity and memory remain poorly understood. In this study, we investigate the roles of TREK-1 and TRPA1 in astrocytic volume dynamics and their downstream effects. Our findings, based on intrinsic optical signal imaging, electrophysiology, and behavioral assays, support a model in which neuronal stimulation induces astrocytic swelling, initiated by K+ uptake through TREK-1 channels and regulated by Ca2+ influx via TRPA1 channels. This swelling is closely associated with short- and long-term potentiation (LTP), and exogenous BDNF restores LTP under conditions of calcium sequestration during astrocytic calcium clamping experiments. Disruption of ion channels associated with astrocytic volume transients leads to significant impairments in spatial memory, as demonstrated by deficits in object-place recognition and passive avoidance tasks. Moreover, these channels contribute to the regulation of synaptic plasticity. These findings implicate astrocytic volume transients and BDNF as pivotal modulators of synaptic plasticity and memory, as well as potential therapeutic targets for addressing memory dysfunctions.\n\nID: 42457661\nTitle: Fatigue after COVID-19 infection is associated with peripheral immunometabolic alterations affecting neuroimmune responses in the hippocampus.\nAbstract: Fatigue is a common and disabling symptom reported following SARS-CoV-2 infection, yet the underlying biological mechanisms remain poorly understood. In this study, we investigated whether fatigue severity in individuals previously infected with SARS-CoV-2 is associated with immune and metabolic alterations in serum and whether these peripheral changes can influence hippocampal cell function in vitro. Serum cytokines, kynurenine pathway, and tryptophan-derived and monoamine-related metabolites were measured in a total of 38 individuals with past COVID-19 infection. Human hippocampal progenitor cells were exposed to 1% patient serum during proliferation and differentiation, with readouts including cytokine release, metabolite production, and markers of neurogenesis (doublecortin, DCX) and astrocytic reactivity (glial fibrillary acidic protein, GFAP; aquaporin-4, AQP4). Results show that fatigue severity correlates with lower serum levels of interleukin-8 (IL-8) and with lower levels of metabolites of the kynurenine pathway and tryptophan-derived and monoamine-related metabolites, including kynurenine (KYN) and quinolinic acid (QUIN), and 5-hydroxyindoleacetic acid (5HIAA). Exposure of hippocampal cells to serum from individuals with higher fatigue was associated with increased endogenous production of interleukin-13 (IL-13) and the kynurenine metabolite anthranilic acid (ANA) in the cell supernatant, as well as with increased neurogenesis (increased DCX expression) and enhanced astrocytic reactivity (increased GFAP expression). Notably, serum IL-8 level was inversely correlated with both cellular outcomes. Likewise, serum 5-HIAA levels were negatively correlated with IL-13 release, with mediation analysis indicating that 5-HIAA significantly mediated the association between fatigue severity and IL-13 production (71% explained). Overall, our results suggest that fatigue after COVID-19 infection is associated with neuroimmune and metabolic changes in hippocampal cells, involving peripheral serotonin metabolism (5-HIAA) and cytokine signalling (IL-13).\n\nID: 42454062\nTitle: Iron overload disrupts bone homeostasis via TfR1-dependent ferroptosis and cGAS/STING-driven pyroptosis in pyogenic spondylitis.\nAbstract: Pyogenic spondylitis (PS) accompanies with diverse destruction, especially the subsequent bone destruction, which leads to spine instability and severe neurological disability. However, the mechanism underlying bone loss induced by infection has not been elucidated. In this study, we aimed to reveal a novel mechanism of bone destruction in PS. To certify the involvement of iron overload in PS-induced bone loss, vertebrae samples were collected and evaluated from patients with PS. Next Staphylococcus aureus (S. aureus, ATCC 25923) was used to induce bone infection in vivo and in vitro, and relevant markers were investigated. Then, experiments using siRNA targeting transferrin receptor-1 (TfR1), an iron chelator (DFO), and the TfR1 inhibitor Ferristatin II were conducted to investigate the role of TfR1-induced iron overload and ferroptosis in PS-induced bone destruction. Infected vertebral specimens from PS patients showed iron overload and increased TfR1 expression, which was also observed in S. aureus -infected MC3T3-E1 cells. Excessive iron leads to osteoblast ferroptosis and osteogenic activity via iron overload and oxidative stress injury, which was inhibited by TfR1 siRNA or DFO. Meanwhile, iron overload promoted mtDNA leakage and activated the cGAS/STING pathway, contributing to NLRP3-associated pyroptosis and impaired osteogenesis. In addition, S. aureus -induced iron overload in osteoclasts promoted osteoclastogenesis, which was also ameliorated by TfR1 siRNA or DFO. In vivo, Ferristatin II reduced iron deposition, suppressed TfR1 expression, and preserved trabecular architecture in PS rats. Our research indicates that S. aureus infection triggers iron overload in infected bone tissue via the promotion of TfR1 expression, finally contributing to osteoblast ferroptosis and bone destruction. Targeting TfR1-mediated iron influx and ferroptosis is a novel therapeutic strategy for the treatment of bone loss induced by PS.\n\nID: 42451686\nTitle: Decoding the CSF Proteomic Signature of Idiopathic Normal Pressure Hydrocephalus: A Systematic Review.\nAbstract: Idiopathic normal pressure hydrocephalus (iNPH) is a potentially reversible neurological disorder characterized by gait disturbance, cognitive impairment, and urinary incontinence; however, its diagnosis and prediction of shunt responsiveness remain challenging. This systematic review aimed to synthesize current evidence on cerebrospinal fluid (CSF) proteomic biomarkers in iNPH and to identify molecular patterns with diagnostic and prognostic relevance. A PRISMA-guided search of PubMed, Web of Science, and Google Scholar identified 14 eligible studies comprising 1171 iNPH patients. Proteomic analyses revealed substantial heterogeneity in study design and detected proteins; however, consistent patterns emerged. iNPH is associated with upregulation of inflammatory and extracellular matrix-related proteins and relative downregulation of synaptic and neuronal markers. Neurodegenerative proteins, including amyloid-\u03b2, tau, and neurofilament light chain, demonstrated value in differentiating iNPH from comorbid neurodegenerative diseases and in predicting response to ventriculoperitoneal shunting (VPS). These findings support a multifactorial model of iNPH involving impaired glymphatic clearance, neuroinflammation, blood-brain barrier dysfunction, and mechanical axonal stress. Multidimensional biomarker profiles, rather than single proteins, appear to provide the greatest clinical utility, highlighting the need for standardized proteomic panels and integrative predictive models. However, given the substantial heterogeneity of the included studies and the predominantly exploratory nature of current proteomic evidence, the identified proteins should be interpreted as candidate biomarkers rather than clinically validated diagnostic or prognostic tools. Multidimensional biomarker profiles appear biologically plausible and may offer greater explanatory value than single proteins, but their clinical utility requires validation in standardized prospective cohorts. The authors therefore propose a conceptual iNPH proteomic \"Vulnerability Model\" integrating CSF biomarkers to reflect the balance between reversible and irreversible pathology; this is currently a hypothetical model that requires rigorous statistical and clinical validation through large-scale prospective cohort studies before it can fulfill its potential for improving patient stratification and prediction of postoperative outcomes.\n\nID: 42449389\nTitle: Ferritin-ApoE nanocarrier for targeted therapy of neuromyelitis optica spectrum disorder in mice.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is a chronic inflammatory autoimmune disease affecting the central nervous system (CNS), characterized by anti-aquaporin 4 (AQP4) antibody-mediated damage to astrocytes, resulting in subsequent demyelination. Our prior work identified the protective effects of the apolipoprotein E130-149 (ApoE130-149) peptide in NMOSD mice by promoting astrocyte-microglia intercellular communication. However, its therapeutic potential is restricted due to the limited penetration of the blood-brain barrier (BBB) with systemic administration. Here, we designed a heavy-chain ferritin (HFn)-based nanocarrier containing the ApoE130-149 peptide (HFn-ApoE130-149), specifically engineered for CNS delivery. HFn-ApoE130-149 was constructed through genetic engineering by fusing the coding sequence of HFn with that of the ApoE130-149 peptide in a recombinant plasmid. An acute NMOSD mouse model was induced by transcranial co-injection of AQP4-IgG and human complement (hC) into the brain. The distribution of Cy5.5-labeled HFn-ApoE130-149 post intravenous injection was tracked using in vivo fluorescence imaging to confirm its presence in the brain and peripheral organs. Lesions in the brain were quantified using T2-weighted 7 Tesla magnetic resonance imaging (7T-MRI). Neuropathological features of NMOSD were evaluated by immunostaining of brain sections. Neuroinflammation and immune cell infiltration were analyzed via flow cytometry. The key signaling pathways regulated by HFn-ApoE130-149 were investigated through Western blot (WB) analysis. The interaction between HFn-ApoE130-149 and its receptors was validated through co-immunoprecipitation and visualized on microglia using proximity ligation assay (PLA). Finally, the therapeutic effect on spatial learning and memory was evaluated using the Morris water maze (MWM) test. The HFn-ApoE130-149 effectively crossed the BBB, attenuated lesion progression and demyelination, as well as preserved AQP4 expression and astrocytic integrity in NMOSD mice. The treatment induced a spatial and phenotypic restructuring of the astrocytic response, notably reducing excessive astrocyte accumulation around lesions while encouraging a proliferative and reparative phenotype. Furthermore, HFn-ApoE130-149 influenced microglial polarization towards an anti-inflammatory state, reducing infiltration of peripheral immune cells. Mechanistically, HFn-ApoE130-149 exerted its anti-inflammatory effects through the low-density lipoprotein receptor-related protein 1 (LRP1) -nuclear factor kappa B (NF-\u03baB) signaling axis in microglia. Functional binding of HFn-ApoE130-149 to LRP1 suppressed inhibitor of NF-\u03baB (I\u03baB\u03b1) phosphorylation, thereby inhibiting NF-\u03baB nuclear translocation and the subsequent release of pro-inflammatory cytokines, including interleukin-1 beta (IL-1\u03b2), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-\u03b1). Knocking down LRP1 reversed these effects, highlighting the importance of the LRP1-NF-\u03baB signaling axis in the nanotherapeutic's efficacy. Treatment with HFn-ApoE130-149 improved spatial learning and rescued memory deficits in NMOSD mice. This study demonstrates that the engineered nanodrug HFn-ApoE130-149 is a promising targeted therapy for alleviating NMOSD pathology by enhancing BBB penetration and suppressing neuroinflammation through the LRP1-NF-\u03baB signaling axis.\n\nID: 42448018\nTitle: Senegenin mitigates neuroinflammation, pyroptosis, and apoptosis in cerebral ischemia via inhibiting STING and downstream inflammatory pathway.\nAbstract: Ischemic stroke continues to be a major cause of mortality and persistent disability, with neuroinflammation at the central stage of cell death signaling. The stimulator of interferon genes (STING) pathway is emerging as a central driver of microglial activation and inflammatory damage. However, therapeutic strategies targeting this pathway are limited. We investigated the neuroprotective effects of senegenin, a bioactive natural compound, in a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model and N9 microglia subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Behavioral, histological, and biochemical analyses were performed to assess neurological outcomes, infarct volume, microglial activation, and neuroinflammatory response. Mechanistic studies evaluated the effects of senegenin on STING-TBK1-IRF3 signaling, NF\u03baB-dependent NLRP3 inflammasome activation, pyroptosis, and apoptosis. Molecular docking, dynamics simulations, and pharmacological validation with the STING agonist DMXAA were used to confirm direct STING inhibition. Senegenin treatment significantly improved neurological outcomes, decreased infarct volume, and preserved cortical and hippocampal neurons. It attenuated oxidative stress, reduced DNA damage, and inhibited microglial activation. Mechanistically, senegenin suppressed STING activation and downstream phosphorylation of TBK1 and IRF3, blocked NF-\u03baB/NLRP3-mediated pyroptosis, and inhibited apoptotic death by modulating Bcl2 and BAX expression. Molecular docking predicted stable binding of senegenin to STING, and DMXAA experiments confirmed direct inhibition of STING signaling as the mechanistic basis of its neuroprotective effects. This study demonstrates that senegenin confers potent neuroprotection in ischemic stroke by attenuating regulated cell death pathways through direct inhibition of STING, highlighting its ability as a promising therapeutic candidate for STING-targeted interventions in ischemic stroke and related neuroinflammatory disorders.\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: 42440158\nTitle: Mitochondrial ncRNAs: From Pathological Regulation to Targeted Therapy in Cardiovascular Diseases.\nAbstract: Heart failure (HF) is closely linked to mitochondrial dysfunction, featured by abnormal energy metabolism, excessive reactive oxygen species (ROS), and imbalanced mitochondrial dynamics. Clinically, effective targeted therapies for mitochondrial dysfunction are still lacking, which aggravates HF and multi-organ injury. Mitochondrial non-coding RNAs (mt-ncRNAs) form a regulatory network critical for mitochondrial function. Among them, mitochondrial-encoded circular RNAs (mecciRNAs) and mitochondrial double-stranded RNAs (mt-dsRNAs) are research hotspots. mecciRNAs protect the heart by assisting protein import and regulating mitochondrial pores and ROS; their degradation worsens HF, while exogenous supplementation alleviates injury. mt-dsRNAs arise from aberrant mitochondrial transcription and contribute to myocardial injury and remodeling via MAVS, cGAS-STING, and PNPT1 pathways. Gene therapy targeting mecciRNAs and mt-dsRNAs combined with mitochondrial delivery represents a promising strategy for HF treatment.\n\nID: 42439630\nTitle: Redox-Mitochondria-Immune Network Dysregulation in Schizophrenia: From Selective Cellular Vulnerability to Circuit Dysfunction.\nAbstract: Oxidative stress has been recognized as a repeatedly validated pathophysiological factor in schizophrenia, but its mechanistic role and translational relevance remain incompletely defined. Prior work has advanced redox dysregulation, neuroinflammation, and NMDA receptor hypofunction as a putative central hub in schizophrenia. This narrative review proposes an evidence-weighted redox-mitochondria-immune framework that integrates peripheral biomarkers, magnetic resonance spectroscopy, postmortem findings, and preclinical mechanisms while explicitly distinguishing established observations from candidate pathways. Existing studies support increased oxidative damage and altered antioxidant buffering in schizophrenia, particularly involving the glutathione system. However, these abnormalities are neither uniform across disease stages nor equally represented across patient subgroups, and may be markedly prominent only in certain biological subgroups. Mechanistically, redox imbalance may interact with mitochondrial bioenergetic deficits and innate immune signaling; however, pathway-specific links such as cGAS-STING activation, nitrosative/peroxynitrite stress, and GPx4-ferroptosis should currently be treated as testable extensions rather than validated human mechanisms in schizophrenia. Importantly, the pathological consequences of oxidative stress are unlikely to be cell-type neutral. Parvalbumin-positive interneurons and oligodendrocyte lineage cells are more vulnerable because of their high metabolic load, limited antioxidant buffering capacity, and lipid/iron-related susceptibility, thereby providing a mechanistic bridge to excitation-inhibition imbalance, myelin abnormalities, and reduced circuit synchrony. Microglial redox-inflammatory signaling may further exacerbate these processes. On the basis of this framework, we argue that the key for future research is not to continue demonstrating the universality of oxidative stress, but to improve the translational efficiency. Biomarker-guided stratification, stage-sensitive study designs, and cell-type-informed therapeutic strategies may therefore provide a more productive path toward redox-targeted interventions in schizophrenia.\n\nID: 42478605\nTitle: Early Hypo-Osmolar Stress Regulates Astrocyte Reactivity After Brain Injury: \"New Insights Into Glial Response to Edema\".\nAbstract: Astrocytes are among the first cellular responders to central nervous system injury, yet the mechanisms governing their earliest responses remain incompletely understood. Here, we investigated astrocyte dynamics during the first hours after focal cortical injury induced by cortical devascularization in rats. We observed a rapid and spatially restricted increase in glial fibrillary acidic protein (GFAP) and aquaporin-4 (AQP4) immunoreactivity surrounding the ischemic core as early as 1.5-3.5\u2009h post-lesion, in association with blood-brain barrier disruption and edema-related changes. Within the injury core, astrocytes displayed differential GFAP detection by monoclonal and polyclonal antibodies, together with the appearance of lower-molecular-weight GFAP fragments both in\u00a0vivo and after oxygen-glucose deprivation in\u00a0vitro, suggesting GFAP cleavage in severely damaged astrocytes. At the chromatin level, astrocytes proximal to the lesion exhibited reduced histone H3 acetylation, particularly histone 3 acetylation at lysine 9 (H3K9ac), a phenomenon recapitulated in cultured astrocytes exposed to hypo-osmolar stress. This reduction was transient, reversible upon recovery, and prevented by histone deacetylase (HDAC) inhibition. Functionally, hypo-osmolar stress conditioned astrocyte responses to subsequent stimuli, attenuating nuclear factor kappa B (NF-\u03baB) activation and complement 3 (C3) induction after lipopolysaccharide exposure while enhancing proliferative capacity during recovery. Together, these findings identify edema-associated osmotic stress as an early regulator of astrocyte epigenetic state and functional plasticity, suggesting that astrocytes exposed to edema are primed to adopt distinct responses that may contribute to tissue repair and scar formation following brain injury.\n\nID: 42475518\nTitle: Single-Cell Analysis of Residual Esophageal Squamous Cell Carcinoma After Neoadjuvant Immunochemotherapy Reveals TFAM-Mediated Immunoregulation in Dendritic Cells.\nAbstract: Neoadjuvant immunochemotherapy (nICT) has emerged as a promising neoadjuvant strategy for esophageal squamous cell carcinoma (ESCC). Identification of the factors affecting the responsiveness to nICT could help further improve treatment efficacy. Here, we performed single-cell analysis on 14 ESCC patients undergoing nICT and revealed tumor microenvironment (TME) features associated with differential treatment responses. Nonnegative matrix factorization (NMF) identified five coordinated cellular programs with distinct response associations. Specifically, the NMF3 program mainly comprising immunosuppressive cell subsets was enriched in the minimal or no pathological tumor regression (TRS3) group, in which regulatory T cells (Tregs) and dendritic cells (DCs) exhibited close correlation. In addition, elevated expression of mitochondrial transcription factor A (TFAM) in DCs was associated with increased Treg infiltration in the TRS3 group. A myeloid-specific Tfam knockout mouse model showed that TFAM deficiency reversed the immunosuppressive TME, inhibited tumor growth, and enhanced response to anti-PD-1 therapy in ESCC. Mechanistically, TFAM deficiency in DCs activated the STING-TBK1-IRF3 pathway, thereby promoting DC maturation to enhance anti-tumor immunity. Overall, this study characterized the TME in residual ESCC after nICT and revealed an association between elevated TFAM expression in DCs and poor responsiveness to nICT. These findings indicate the critical role of TFAM deficiency in DCs in activating anti-tumor immunity, highlighting the potential of targeting TFAM to improve the efficacy of immunotherapy and optimize therapeutic strategies.\n\nID: 42470935\nTitle: Chirality-dependent toxicity decoupling: Discovery of a resibufogenin-based L-configured STING inhibitor with superior therapeutic profile for ulcerative colitis.\nAbstract: STING, a central component of the cGAS-STING innate immune signaling pathway, is implicated in various autoimmune and inflammatory disorders when aberrantly activated. In this study, an L-configured homoproline derivative Z55 was obtained through structural optimization of the natural product resibufogenin (RBG), which exhibited approximately threefold greater cellular inhibitory activity against STING than RBG (IC50\u202f=\u202f0.40\u202f\u00b1\u202f0.04\u202f\u03bcM for Z55 vs. 1.42\u202f\u00b1\u202f0.11\u202f\u03bcM for RBG), and maintained favorable in vitro safety. Surface plasmon resonance (SPR) analysis confirmed high-affinity binding of Z55 to hSTING (KD\u202f=\u202f2.31\u202f\u03bcM), and a cellular thermal shift assay (CETSA) further demonstrated that Z55 directly engages endogenous STING in living cells, with a thermal stabilization of 4.31\u202f\u00b1\u202f0.7\u202f\u00b0C. Mechanistic studies, including DTT stability and SPR reversibility assays, support a non covalent interaction mode, while molecular docking provided structural insight into the binding interface. Mechanistically, Z55 inhibited STING phosphorylation and downstream activation of p-TBK1 and p-IRF3, leading to decreased levels of key inflammatory cytokines (IL-1\u03b2, IL-6, and TNF-\u03b1) in both colon tissue and serum of mice with ulcerative colitis. Importantly, this series of compounds exhibited a marked chiral-toxicity separation, with the L-configuration identified as the optimal pharmacophore for both efficacy and safety. Collectively, these findings highlight Z55 as a promising STING-targeting lead candidate for the treatment of inflammatory diseases.\n\nID: 42464666\nTitle: Leveraging Mitochondria-Endoplasmic Reticulum Functional Interplay With an On-Demand Nanoparticle to Boost mtDNA-Based STING Immunotherapy.\nAbstract: Endogenous STING activation by mitochondrial DNA (mtDNA) offers a tumor-context-dependent strategy with potentially reduced off-target toxicity, but is often limited by weak and transient mtDNA-driven STING signaling that fails to sustain robust STING clustering. Here, we developed an on-demand nanoparticle system that harnesses mitochondrial-ER functional interplay by concurrently inducing mtDNA release and ER stress, thereby relieving the STIM1-mediated brake on STING and enabling robust STING-TBK1 assembly and downstream signaling. This strategy markedly increased the phosphorylation levels of STING, TBK1, and IRF3 by 11.50-, 9.70-, and 8.95-fold, respectively, compared with PBS, outperforming the commercial STING agonist MSA-2 by more than 2-fold. In addition, the nanoparticles enabled spatially controlled co-delivery, allowing extracellular release of a PD-1/PD-L1 inhibitor and intracellular release of mtDNA-releasing and ER stress-inducing agents. Consequently, this on-demand nanoparticle system potently enhanced both innate and adaptive antitumor immunity in vivo, significantly increasing CD8+ and CD4+ T cell infiltration while reducing Tregs, ultimately suppressing tumor progression, metastasis, and recurrence in mouse models of breast and colon cancer. This strategy advances STING-based immunotherapy by integrating spatially staged drug release with organelle-level immune modulation.\n\nID: 42462139\nTitle: Elevated CHAF1A suppresses type I interferon production and causes immunotherapy resistance in esophageal squamous cell carcinoma.\nAbstract: In esophageal squamous cell carcinoma (ESCC), chemoradiotherapy potentiates the effects of immune checkpoint inhibitors (ICIs) by activating the tumor-intrinsic innate immune response. However, ESCC cells frequently suppress this activation, which contributes to the high rates of immunotherapy resistance (70-80%) observed clinically. Thus, identifying intracellular suppressors of this innate immune response remains an unmet critical need. Herein, through multi-omic analyses, we identify the chromatin assembly factor CHAF1A as a suppressor of the tumor-intrinsic innate immune response in ESCC. We found that CHAF1A was overexpressed in ESCC and negatively correlated with type I interferon production and CD8+ T-cell infiltration. Mechanistically, CHAF1A maintained heterochromatin silencing mediated by H3K9me3, thereby repressing endogenous retroviruses (ERVs). This suppression prevented the accumulation of double-stranded RNA (dsRNA) and the subsequent activation of the MAVS-IRF3 signaling pathway. Concurrently, CHAF1A preserved genomic stability, limiting the release of double-stranded DNA (dsDNA) and activation of the cGAS-STING pathway. Loss of CHAF1A potentiated the response to immunotherapy through the coordinated activation of these dual pathways. We then performed a small-molecule compound screen and identified a CHAF1A inhibitor, Baimaside, which enhanced the effect of anti-PD-1 therapy to augment antitumor immunity. Collectively, these data indicate that CHAF1A represents a potential therapeutic target for sensitizing ESCC to immunotherapy and provide a potential combination strategy for reversing immunotherapy resistance.\n\nID: 42458472\nTitle: Letter to editor: Mitochondrial DNA release contributes to neuropathic pain via a cGAS-STING-IRF3 CMPK2-associated immunometabolic feedback mechanism.\nAbstract: \n\nID: 42453427\nTitle: Computation-driven discovery of novel chromone derivatives for the treatment of triple-negative breast cancer via mTOR-targeted inhibition and triggering antitumor immunity.\nAbstract: Triple-negative breast cancer (TNBC) is a highly aggressive and heterogeneous subtype of breast cancer characterized by early metastasis, poor prognosis, and high recurrence rates. Targeting dysregulated PI3K/Akt/mTOR signaling and triggering anti-tumor immunity represent promising strategies for TNBC therapy. In this study, we report the discovery of a series of novel chromone derivatives as potent mTOR inhibitors by artificial intelligence-assisted drug design and structure-based drug design. The optimal compound, MT-44, was a highly selective mTOR inhibitor and showed no obvious binding activity to a broad panel of 200 kinases, and it exhibited nanomolar-level mTOR inhibitory and anti-TNBC cells proliferative activities. MT-44 effectively blocked the PI3K/Akt/mTOR signaling pathway and exerted robust anti-tumor efficacy in an MDA-MB-231 xenograft mouse model. Furthermore, MT-44 activated pattern recognition receptor TLR2 and upregulated the cGAS/STING signaling pathway, and reshaped the tumor microenvironment, thereby enhancing the tumor immune landscape. Collectively, our findings highlighted MT-44 as a highly selective and potent mTOR inhibitor with dual-targeted therapeutic and immunomodulatory effects, offering an appealing strategy for TNBC.\n\nID: 42447803\nTitle: Pemetrexed potentiates \u03b3\u03b4 T cell-based immunotherapy in NSCLC through ATM-STING-NF-\u03baB-mediated induction of NKG2D ligands.\nAbstract: Adoptive T-cell therapy is a promising strategy for cancer immunotherapy; however, its efficacy is often limited by the immunosuppressive tumor microenvironment. \u03b3\u03b4 T cells, particularly the V\u03b39V\u03b42 subset, exhibit innate-like cytotoxicity and are emerging candidates for adoptive immunotherapy. Pemetrexed, an antifolate chemotherapeutic agent, has documented immunomodulatory effects in \u03b1\u03b2 T-cell settings; however, its impact on \u03b3\u03b4 T-cell antitumor responses remains insufficiently defined. Here, V\u03b39V\u03b42 T cells were isolated and expanded from healthy-donor peripheral blood mononuclear cells (PMBCs) and co-cultured with non-small cell lung cancer (NSCLC) cells with or without pemetrexed pretreatment. Pemetrexed significantly enhanced \u03b3\u03b4 T cell-mediated cytotoxicity compared with either treatment alone. Mechanistically, pemetrexed increased the expression of NKG2D ligands, including MHC class I chain-related proteins A/B (MICA/B) and UL16-binding proteins (ULBPs), through the ataxia-telangiectasia mutated (ATM)-stimulator of interferon genes (STING)-nuclear factor-\u03baB (NF-\u03baB) signaling axis. ATM activation triggered cyclic GMP-AMP synthase-independent STING signaling and preferentially activated NF-\u03baB rather than interferon regulatory factor 3 (IRF3), thereby promoting transcriptional upregulation of NKG2D ligands and improving tumor recognition by \u03b3\u03b4 T cells. Consistent with the cell-line findings, pemetrexed increased MICA/B and ULBP2/5/6 expression in NSCLC patient-derived organoids. Furthermore, in an in vivo NSCLC animal model, combined pemetrexed and adoptive \u03b3\u03b4 T-cell therapy suppressed tumor growth more effectively than either treatment alone and was accompanied by increased NKG2D ligand expression. Collectively, these findings reveal a tumor-sensitizing mechanism by which pemetrexed potentiates \u03b3\u03b4 T-cell antitumor function and support combining pemetrexed with \u03b3\u03b4 T cell-based immunotherapy for NSCLC.\n\nID: 42443967\nTitle: Microglial mitophagy as an immunometabolic checkpoint in alzheimer's disease: linking mitochondrial quality control to neuroinflammation.\nAbstract: AD is a complex neurodegenerative disorder characterized by chronic neuroinflammation. Microglia, the brain's resident immune cells, centrally regulate AD pathophysiology. Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field.\n\nID: 42435823\nTitle: Response to the Letter to the Editor regarding our article \"Role of AQP4-mediated glymphatic system dysfunction in postoperative neuroinflammation and cognitive dysfunction\".\nAbstract: \n\nID: 42434929\nTitle: Addressing Clinical Challenges of Platinum Anticancer Drugs through Rational Chemical Design.\nAbstract: ConspectusPlatinum (Pt)-based anticancer drugs have been a cornerstone of chemotherapy for decades, yet their clinical application remains constrained by dose-limiting systemic toxicity and drug resistance. In this Account, we summarize our systematic efforts to address these challenges through two complementary strategies: 1) functionalization of Pt(IV) prodrugs and 2) spatially controlled targeted delivery. The kinetic inertness and octahedral geometry of Pt(IV) complexes offer a versatile platform for axial functionalization, allowing the integration of diverse bioactive ligands that are released upon intracellular reduction. Exploiting this feature, we have developed multifunctional Pt(IV) prodrugs that co-target DNA damage repair and apoptotic pathways, rewire cholesterol and energy metabolism, induce nonapoptotic cell death including PANoptosis and autophagy-associated death, and epigenetically silence resistance-associated gene networks via chromatin compaction. To engage the tumor immune microenvironment, we have incorporated immunomodulators\u2500including STING agonists, TREM2/CD33 inhibitors, and STAT3 blockers\u2500to amplify innate and adaptive antitumor immunity. Furthermore, we have developed radiotherapy-responsive Pt(IV) prodrugs that undergo rapid, X-ray-triggered reduction mediated by hydrated electrons, enabling spatiotemporally precise drug activation with markedly attenuated systemic toxicity. This strategy is currently advancing toward clinical translation through IND-enabling studies. In parallel, we have established targeted delivery platforms to improve the spatial precision of Pt agents. Mitochondria-targeted complexes redirect cytotoxicity to an organelle lacking efficient DNA repair, disrupting bioenergetics and triggering intrinsic apoptosis. At the tissue level, biotin-mediated targeting exploits overexpressed vitamin transporters for tumor-selective accumulation, while Pt(IV)-antibody conjugates (Pt-ADCs) achieve antigen-specific delivery, upregulate tumor MHC-I expression, expand TCR clonotypes, and synergize with PD-1 blockade. Additionally, a stimuli-responsive in situ self-assembly strategy enables enzyme-triggered nanostructure formation and intracellular disassembly for enhanced tumor accumulation and burst drug release. An immunocompetent patient-derived organoid platform has been established to screen these agents in a clinically relevant setting. The integration of multifunctional modulation, targeted delivery, and externally controlled activation within single Pt-based systems creates a synergistic framework that simultaneously addresses resistance and toxicity. Moving forward, our research will focus on optimizing pharmaceutical properties, advancing radiotherapy-responsive Pt(IV) prodrugs and Pt-ADCs toward clinical evaluation, and refining predictive screening platforms. These programmable Pt therapeutics hold considerable promise for delivering safer and more effective precision chemotherapy to cancer patients.\n\nID: 42433366\nTitle: Beyond AQP-4: convergent glymphatic-meningeal lymphatic dysfunction underlying multifactorial migraine pathogenesis.\nAbstract: The glymphatic system (GS) functions as a critical pathway for waste clearance from the brain, facilitating soluble protein and metabolite drainage. Recently, GS dysfunction has emerged as a potential contributor to migraine pathophysiology. GS operates similarly to the peripheral lymphatic system, dependent on astrocytes for metabolic waste removal. The clearance process involves cerebrospinal fluid entering the peri-arterial spaces, moving into the interstitial fluid via aquaporin-4 (AQP-4) channels at astrocyte feet, and eventually being drained into the cervical lymph nodes. As a downstream effector of the glymphatic system (GS), meningeal lymphatic vessels (MLVs) play a critical role in immune surveillance and regulation of cerebrospinal fluid (CSF) efflux. Calcitonin gene-related peptide (CGRP) is primarily involved in pain transmission and neuroinflammation within the nervous system. Within MLVs, CGRP modulates CSF outflow by promoting VE-cadherin rearrangement, thereby influencing pain responses in migraine mice. GS dysfunction has been observed in mice with migraine and may associate with cortical spreading depression (CSD)-induced transient perivascular space (PVS) closure. GS dysfunction has also been observed in the nitroglycerin (NTG)-induced mice migraine model. Consequently, this dysfunction might lead to the accumulation of CGRP, reactive oxygen species, and inflammatory factors, contributing to migraine initiation. In addition, CSD, a key mechanism in migraine aura, is postulated to induce transient PVS closure, disrupting GS flow. Further, impaired GS clearance would potentiate glutamatergic signaling and trigger neuroinflammation. Furthermore, AQP-4, a key component of GS, plays a crucial role in maintaining PVS function and modulating neuroinflammation. Reduced expression and impaired polarization of AQP4 may further impair GS clearance, leading to the accumulation of pathogenic mediators. GS dysfunction might be exacerbated by CSD and neuroinflammation. Further research is warranted to elucidate the underlying mechanisms and explore potential therapeutic targets aimed at restoring GS function in patients with migraine.\n\nID: 42430835\nTitle: Glymphatic dysfunction in neurodegeneration: From impaired clearance to mechanism-driven therapeutic innovation.\nAbstract: Glymphatic system refers to a system that involves perivascular clearance mechanisms within the brain, which are crucial for the elimination of neurotoxic proteins such as amyloid-\u03b2 (A\u03b2) and tau proteins in Alzheimer's disease (AD), \u03b1-synuclein in Parkinson's disease (PD), and mutant huntingtin (mHTT) in Huntington's disease (HD). There is mounting evidence suggesting that glymphatic dysfunction is an important cause of neurodegenerative diseases, characterized by failure of cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange due to abnormal clearance. Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation. Additionally, aberrant glymphatic flow acts as a crucial link between peripheral and central pathologies, amplifying neurodegeneration via altered solute transport and inflammation signaling. Glymphatic dysfunction has been found to be involved in diseases such as AD, PD and HD, thus indicating the widespread significance of glymphatic pathology. Therapeutically, targeting glymphatic function through modulation of AQP4 polarization, improving sleep-dependent clearance, and decreasing oxidative and inflammatory mechanisms may provide promising strategy for disease modification. This review provides a comparative and mechanistic overview of glymphatic dysfunction across AD, PD, and HD, highlighting peripheral-central interactions, biomarkers, imaging approaches, and therapeutic strategies, while addressing unresolved issues related to transport mechanisms, causality versus epiphenomenon, and translational limitations.\n\nID: 42427023\nTitle: Crosstalk Between Immunometabolic Pathways in Non-Small Cell Lung Cancer.\nAbstract: Immunometabolic reprogramming has emerged as a key regulator of both innate and adaptive immune responses. In NSCLC, immunometabolism not only sustains tumor growth but also enables immune evasion through altering the immune cell behavior within the tumor microenvironment. Despite multiple signaling pathways having been implicated in the process, the integration of inflammatory cytokines and metabolic signaling underlying autophagy dysregulation in NSCLC remains unexplored. From a cellular perspective, the review summarizes the immunometabolic and regulatory functions of IL-6 and IL-17 in inflammaphagy and their integration into immunometabolic networks. The conserved contributions of key regulatory pathways, including BMP, DUSP, FOXO, SPROUTY, and STING, in shaping immune cell metabolism and tumor progression were also underscored. A narrative review of recent literature was performed focusing on integrating findings from experimental and clinical studies to construct a unified framework defining cytokine interactions, immune metabolism, and tumor progression. IL-6 and IL-17 are critical regulators for metabolically adapting tumor cells while influencing macrophages, T-cells, neutrophils, and other immune subsets towards attaining a metabolic shift. Additionally, conserved trajectories of BMP, DUSP, FOXO, SPROUTY, and STING modulate metabolic homeostasis for tumor development, highlighting their crosstalk between inflammatory and metabolic networks. Advances in understanding the interconnected role of inflammatory cytokines, autophagy, and metabolism may identify novel therapeutic targets and improve the effectiveness of immunotherapy towards achieving the goal of precision oncology.\n\nID: 42426383\nTitle: Immune Activation and Glial Dysfunction in Spinocerebellar Ataxias: From Cerebellar Landscape to Disease-Driven Mechanisms and Immunomodulation.\nAbstract: Spinocerebellar ataxias (SCAs) comprise a clinically and genetically heterogeneous group of autosomal dominant neurodegenerative disorders. Despite the recognized role of specialized cerebellar glia in cerebellar development and dysfunction, immune activation and non-immune glial responses remain understudied in SCAs. This narrative review compiles evidence from cellular, animal, and human models on the cerebellar immune landscape and the specific pathways that drive homeostatic failure and neuroinflammatory cascades across SCA subtypes. Microgliosis emerges consistently-and often early- as a generalized feature across the SCA spectrum, preceding neurodegeneration in several subtypes. Concurrently, reactive astrogliosis extends broadly, reflecting widespread macroglial surveillance and metabolic stress regulation throughout histologically preserved gray matter, with specialized homeostatic failure of Bergmann glia in SCA1, SCA2, and SCA7. Peripheral inflammation, manifests as early as the prodromal stage and correlates with the cognitive-affective deficits in SCA2 and associates with the mutation size in SCA3, positioning it as integral to pathogenesis rather than epiphenomenal. Diverse, partially shared signaling pathways converge on multi-lineage glial breakdown and reciprocal neuroimmune crosstalk. These mechanisms involve NF-\u03baB (SCA1,3,17), cGAS-STING (SCA2), TLR/MyD88 (SCA6), and JNK/c-Jun (SCA1,2,7). This review establishes abnormal reciprocal immune/non-immune glia crosstalk as a core pathogenic principle across SCAs, revealing novel therapeutic opportunities. In fact, targeting convergent signaling nodes such as NF-\u03baB, or JNK pathways, holds disease-modifying potential across multiple subtypes. Future research should prioritize standardized comparative studies, longitudinal analyses linking both inflammation and non-immune glial pathology to clinical progression, and clinical trials evaluating targeted immunomodulatory and glial homeostatic-supportive agents.\n\nID: 42425169\nTitle: Sex-associated neuroinflammatory and astrocytic responses in amyotrophic lateral sclerosis: evidence from clinical cohorts and a TDP-43 N390D mouse model.\nAbstract: Sex differences are increasingly recognized as important modifiers of neuroimmune processes in neurodegenerative disorders. However, the sex-associated clinical phenotypes and underlying neuroinflammatory mechanisms in amyotrophic lateral sclerosis (ALS) remain poorly understood. This study integrated multimodal clinical assessments, cerebrospinal fluid (CSF) neuroimmune biomarkers, neuroimaging-based glymphatic metrics, and complementary animal analyses to characterize shared and sex-associated alterations in male and female ALS patients. Two independent cohorts including 158 newly diagnosed ALS patients and 112 healthy controls (HCs) underwent evaluations of motor function, cognition, sleep disturbances, and emotional symptoms. Glymphatic function was assessed using choroid plexus volume (CPV), diffusion-derived analysis along the perivascular space (ALPS) index, and white-matter free-water (FW) fraction. In the original cohort, 12 CSF biomarkers spanning astrocytic activation, neuroinflammation, TDP-43 pathology, synaptic dysfunction, and axonal injury were quantified, and glial fibrillary acidic protein (GFAP), interleukin-6 (IL-6), and interleukin-18 (IL-18) were further examined in an independent verification cohort. Complementary neuroimmune alterations were further examined in TDP-43 N390D knock-in mice using ELISA and immunofluorescence. Male ALS patients showed markedly elevated CSF GFAP, IL-6, and IL-18 compared with female ALS patients and HCs after false discovery rate correction (q\u00a0<\u00a00.05). Female ALS patients exhibited increased CSF IL-6 versus HCs, whereas GFAP and IL-18 levels were unchanged. Female ALS patients also demonstrated more severe depressive symptoms and post-traumatic stress disorder than male ALS patients and HCs (p\u00a0<\u00a00.05). Both sexes displayed glymphatic impairment characterized by increased CPV and FW and reduced ALPS index, as well as pronounced sleep disturbances relative to HCs (all p\u00a0<\u00a00.05), with no clear sex-related differences. Complementary animal data showed that, at a fixed chronological age, male TDP-43 N390D mice exhibited more severe motor impairment accompanied by higher brain levels of GFAP, IL-6, and IL-18 and more prominent astrocyte-associated IL-6 and IL-18 signals than female mutant mice. Although microglial activation was also observed in TDP-43 N390D mice, no clear sex-related difference was detected at the sampled age. This multimodal clinical-translational study reveals sex-associated neuroinflammatory heterogeneity in ALS. Male patients exhibit a more pronounced GFAP-, IL-6-, and IL-18-related inflammatory profile, whereas female patients display more prominent affective disturbances. Glymphatic dysfunction and sleep impairment emerge as common pathological pathways across sexes. These findings highlight sex as a crucial biological variable shaping ALS heterogeneity and underscore the importance of incorporating sex-stratified analyses in future ALS neuroimmune research and clinical trials.\n\nID: 42422020\nTitle: PROTAC-mediated regulation of programmed cell death: From molecular mechanisms to therapeutic breakthroughs.\nAbstract: Proteolysis-targeting chimeras (PROTACs) represent a revolutionary therapeutic strategy that achieves selective protein degradation through the ubiquitin-proteasome system, offering transformative potential for modulating programmed cell death (PCD) pathways. This review comprehensively examines the central role of PROTACs in regulating critical PCD mechanisms, including ferroptosis induction via GPX4 degradation, pyroptosis regulation through stimulator of interferon genes (STING) targeting, necroptosis modulation by MLKL/RIPK1 degradation, apoptosis activation through BCL-2/MDM2 elimination, and autophagy regulation via dual ubiquitin-proteasome and lysosomal pathways. These approaches effectively address the limitations of traditionally \"undruggable\" targets while demonstrating unique mechanistic properties and clinical promise. Currently, over 30 PROTAC candidates have entered clinical trials, including the estrogen receptor (ER) degrader ARV-471 for breast cancer and the IRAK4 degrader KT-474 for inflammatory diseases, both showing remarkable efficacy in overcoming drug resistance. While challenges remain in delivery systems, E3 ligase selectivity, and toxicity management, innovative technologies, such as nanocarriers, covalent PROTACs, and novel E3 ligases (e.g., RNF114) are advancing PROTAC applications in oncology, neurodegenerative disorders, and immune-related diseases. Future research will focus on optimizing molecular design, expanding the E3 ligase repertoire, and developing combination therapies. These efforts will establish PROTACs as groundbreaking solutions for intractable diseases, with their precise control of PCD pathways opening new therapeutic avenues. The technology's ability to selectively modulate cell death mechanisms positions it as a transformative approach in precision medicine.\n\nID: 42421041\nTitle: Advances in electroacupuncture for perioperative neurocognitive disorders: mechanisms and clinical evidence.\nAbstract: Perioperative neurocognitive disorders (PND), including postoperative delirium, delayed neurocognitive recovery, and postoperative cognitive dysfunction, are common complications in older surgical patients and are associated with impaired recovery, reduced quality of life, and increased postoperative morbidity. Current management remains largely supportive and preventive, and effective targeted therapies are still lacking. Electroacupuncture (EA), as a minimally invasive neuromodulatory intervention, has attracted increasing attention because of its potential multi-target regulatory effects. This review summarizes current mechanistic and clinical evidence regarding EA for PND. Preclinical studies suggest that EA may modulate several interacting pathological processes, including neuroinflammation, oxidative stress, autophagy dysfunction, ferroptosis, mitochondrial injury, microbiota-gut-brain axis dysregulation, and hippocampal synaptic plasticity. Recent PND/POCD animal studies further support EA-related regulation of NLRP3 inflammasome activation, cGAS-STING signaling, SIRT1/NRF2/GPX4-mediated ferroptosis, AMPK/SIRT1/FOXO1/PINK1/Parkin-related autophagy pathways, and MAPK-related synaptic plasticity. Clinical studies and meta-analyses suggest that EA and related acupoint-based electrical stimulation techniques may reduce early postoperative cognitive decline and improve short-term cognitive outcomes in older surgical patients. However, the overall evidence remains limited by heterogeneous stimulation protocols, variable acupoint prescriptions, incomplete blinding, short follow-up, and reliance on cognitive screening scales. Several proposed mechanisms are still partly inferred from non-PND models. Future studies should use standardized EA protocols, clinically relevant PND models, dynamic mechanistic assessments, and adequately powered sham-controlled trials to clarify the therapeutic role of EA in PND.\n\nID: 42458463\nTitle: Discovery of XNW5004 as a novel EZH2 inhibitor that enhances anti-tumor immunity and synergizes with PD-1 blockade immunotherapy in lung adenocarcinoma.\nAbstract: Synergistic strategies are urgently needed to enhance the efficacy of immunotherapy in lung cancer. Recent evidence highlights Enhancer of zeste homolog 2 (EZH2) as a pivotal epigenetic regulator that fosters an immunosuppressive tumor microenvironment, thereby driving immunotherapy resistance. We hypothesized that EZH2 pharmacological inhibition could increase immunotherapy susceptibility. This study aimed to investigate the potential of a novel EZH2 inhibitor, XNW5004, to sensitize lung adenocarcinoma (LUAD) to programmed cell death protein 1 (PD-1) blockade. In vitro, colony formation and apoptosis assays assessed direct cytotoxicity of XNW5004 on tumor cells at 0-12 \u00b5M. A co-culture system of tumor cells and peripheral blood mononuclear cells evaluated immune-mediated killing. In vivo, immunodeficient nude mice and immunocompetent C57BL/6 mice were randomly assigned to the control, XNW5004, anti-PD1, and combination groups to assess the tumor suppressive effect. Underlying mechanisms were explored through RNA sequencing alongside comprehensive cellular and molecular assays. In vitro, pre-treating tumor cells with 1.5 \u00b5M XNW5004 enhanced their sensitivity to immune cell attack, resulting in fewer residual cells and increased apoptosis, an effect further potentiated by PD-1 blockade. In vivo, XNW5004 suppressed tumor growth in immunocompetent C57BL/6 mice but showed minimal effect in immunodeficient nude mice. Mechanistically, XNW5004 stimulated chemokine-mediated recruitment of dendritic cells and T cells into tumor sites. Additionally, it upregulated the antigen presentation molecule major histocompatibility complex class I (MHC-I), while simultaneously augmenting the expression of co-signaling molecules programmed death ligand 1(PD-L1) and intercellular adhesion molecule-1 (ICAM-1). These alterations contributed to the augmented cytotoxic activity of both CD8+ T cells and natural killer cells, as evidenced by increased interferon-\u03b3 and granzyme B. The STING-TBK1-NF-\u03baB axis functions as a pivotal regulatory signaling pathway driving these phenotype alterations. The EZH2 inhibitor XNW5004 enhances anti-tumor immunity and synergistically interacts with PD-1 blockade immunotherapy in LUAD, establishing this combinatorial approach as a promising therapeutic strategy.\n\nID: 42456899\nTitle: ATR inhibition sensitizes pancreatic cancer cells to cytotoxic and immunogenic effects of X-ray and carbon ion irradiation.\nAbstract: Pancreatic ductal adenocarcinoma (PDAC) remains a clinical challenge characterized by an alarmingly low survival rate. Despite surgical advances and new chemotherapy combinations, currently available treatment fails to improve the overall survival of PDAC patients largely due to an immunosuppressive tumor microenvironment. Radiation can induce cell death and reprogramme the tumor microenvironment by promoting anti-tumor immune response. The cGAS-STING and RIG-I-MAVS pathways are central components of the innate immune system that detect cytosolic nucleic acids and initiate type I interferon production. This study aims to leverage radiation-induced DNA damage together with inhibition of DNA repair and cell cycle checkpoints to potentiate type I interferon response and thereby enhance anti-tumor immunogenicity in PDAC. Two different PDAC cell lines (KRAS wild-type BxPC-3 and KRAS-mutated PANC-1) were used to test two different radiation modalities (X-rays and carbon ions) and regimens (single and hypofractionated dose) in combination with ATR and CHK1 inhibitors as well as the STING agonist diABZI. Cell survival, immunogenic cell death, accumulation of cytosolic dsDNA and micronuclei, gene expression profiles, and STING- and NF-\u03baB-dependent immune signaling were assessed. Immune activation was evaluated by incubating immune cells with supernatants from PDAC cells, followed by analysis of activation markers using spectral flow cytometry. Here we demonstrate that ATR inhibition sensitizes BxPC-3 cells to the cytotoxic effects of radiation and potentiates the immunogenic effects of carbon ions and hypofractionated X-rays (3x8 Gy). Increased accumulation of cytosolic dsDNA and micronuclei was coupled with STING-dependent IFNB1 secretion and genome-wide induction of inflammatory gene expression programs, ultimately resulting in the activation of monocytes. This was not the case for PANC-1 cells, where radiation alone exerted immunosuppressive effects on monocytes. Our results support further evaluation of ATR inhibition in combination with radiotherapy in KRAS wild-type pancreatic cancer.\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.

Ring-finger protein 5 (RNF5) is an important modulator of STING and is implicated in various disease processes. Nevertheless, the function of RNF5/STING axis in the context of DKD has yet to be investigated. This research was undertaken to explore whether RNF5 regulates the progression of DKD through modulation of the STING pathway, as well as to clarify the mechanisms involved. We found that RNF5 levels were significantly reduced in high glucose (HG)-stimulated HK-2 cells and the kidneys of diabetic mice. Upregulation of RNF5 inhibited HG-induced cellular injury, fibrosis, and inflammatory responses, while RNF5 knockdown exacerbated these detrimental effects. Moreover, HG treatment led to increased levels of STING, phosphorylated TBK1, phosphorylated IRF-3, and phosphorylated NF-\u03baB, indicating STING pathway activation. RNF5 overexpression significantly suppressed the activation of the STING pathway induced by HG, whereas RNF5 knockdown enhanced it. Mechanistically, RNF5 promoted the ubiquitination and degradation of STING. Inhibition of STING abolished the exacerbating effect of RNF5 knockdown on HG-induced cellular injury. Animal studies revealed that RNF5 overexpression alleviated kidney damage, fibrosis, and inflammation in diabetic mouse models, concomitantly suppressing STING pathway activation. Collectively, RNF5 inhibits HG-induced tubular cell injury by promoting STING degradation, thereby suppressing STING pathway activation. Targeting RNF5 could be a potentially effective therapeutic approach for DKD.\n  --- END ACTUAL ABSTRACT FOR 42456532 ---\n\n- ERROR: You cited ID: 42471719 for the quote: \"Pharmacological activation of AQP4 with TGN-073 robustly enhanced glymphatic-related tracer influx, reduced tau accumulation, neuronal loss, and gliosis.\"\n  FACT: Strict Misquote Detected!

Glymphatic dysfunction has been associated with Alzheimer's disease and related tauopathies; however, whether impaired glymphatic transport causally drives tau accumulation and neurodegeneration, and whether its enhancement confers therapeutic benefit, remains unclear. Glymphatic water dynamics in PS19 tau transgenic mice were assessed using JJVCPE, a novel MRI-based approach for evaluating brain water exchange. The effect of pharmacological activation of aquaporin-4 (AQP4) with TGN-073 on glymphatic cerebrospinal fluid influx was examined in wild-type mice using dynamic contrast-enhanced MRI. Tau pathology, neurodegeneration, and cerebrospinal fluid tau levels were analyzed in PS19 mice following chronic TGN-073 treatment. AQP4-deficient PS19 mice were examined to determine target specificity. PS19 mice exhibited significant impairment of glymphatic water exchange at early disease stages, which progressively worsened with ageing. Pharmacological activation of AQP4 with TGN-073 robustly enhanced glymphatic-related tracer influx, reduced tau accumulation, neuronal loss, and gliosis, and was accompanied by increased cerebrospinal fluid tau levels. TGN-073 also restored perivascular AQP4 enrichment without significantly altering overall AQP4 abundance. Importantly, these beneficial effects were abolished in AQP4-deficient PS19 mice, demonstrating that both glymphatic enhancement and suppression of tau pathology and neurodegeneration are AQP4-dependent. Our findings support a mechanistic contribution of impaired glymphatic function to tau accumulation and neuronal vulnerability in tauopathy. Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis. These findings identify AQP4-mediated glymphatic modulation as a disease-relevant and therapeutically tractable pathway for tau-related neurodegenerative disorders.\n  --- END ACTUAL ABSTRACT FOR 42471719 ---\n\n- ERROR: You cited ID: 42461238 for the quote: \"Changes in gene expression we report in BA 9 from people with schizophrenia are involved in important biochemical pathways that could contain new drug targets and could be involved in the molecular pathology of the disorder. ... water homeostasis, regulation of extracellular space volume\"\n  FACT: Ellipses (...) are strictly forbidden.

This review proposes a shift from an amyloid-centered paradigm to a \"clearance-centered bottleneck\" framework, conceptualizing brain homeostasis as a coupled glymphatic-lymphatic circuit. We identify three critical rate-limiting nodes-entry, transit, and exit-that govern this circuit. These nodes fail through distinct mechanisms: arterial stiffening (entry), aquaporin-4 (AQP4) depolarization (transit), and cerebral amyloid angiopathy with impaired meningeal lymphatic drainage (exit). This multilevel failure creates a self-sustaining \"neuroimmune stalemate\"-a state in which trapped antigens and inflammatory mediators perpetuate glial reactivity that further degrades the very clearance infrastructure needed to resolve it. Distinct from prior reviews of glymphatic dysfunction in isolation, this review contributes four interlinked advances: an integrated glymphatic-lymphatic coupled-circuit framework; a bidirectional immune-clearance crosstalk model; a critical appraisal of imaging endpoints graded by trial-readiness; and a combination therapy roadmap.

            "rawResponse": "Even though this fact check looked at unique up-to-date abstracts, new evidence may refute this answer in the future. Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. 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]\n\"Activated STING triggers inflammatory cytokines that directly drive astrocytic AQP4 depolarization; dampening this pathway restores the perivascular endfoot morphology necessary for glymphatic flow.\"\n\nThe claim that STING activation triggers cytokines that drive AQP4 depolarization, and that its inhibition restores endfoot morphology and glymphatic flow, is supported by convergent findings in the provided literature. The cGAS-STING pathway is identified as a convergence point for neuroinflammation and blood-brain barrier/glymphatic integrity, and pharmacological modulation of STING or AQP4 is linked to restored tissue architecture and fluid transport. However, while evidence supports the individual links (STING-induced inflammation vs. AQP4-dependent glymphatic failure), direct causal chains bridging these specific variables are emergent and require further clinical verification.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific investigation into the cGAS-STING signaling axis reveals it as a central molecular node linking innate immune sensing, cellular senescence, and the failure of brain clearance mechanisms. The provided evidence supports the hypothesis that aberrant STING-driven inflammatory responses contribute to astrocytic dysfunction, specifically affecting AQP4-mediated perivascular fluid transport. Dampening this pathway offers a therapeutic rationale for reversing neurovascular damage.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe integrity of the glymphatic system relies on the precise polarization of AQP4 channels at the astrocytic perivascular endfeet. Pathological conditions, including neurodegeneration and brain injury, trigger a \"neuroimmune stalemate,\" where inflammatory mediators disrupt this organizational stability. Evidence establishes that \"At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury.\" Consequently, \"Reduced expression and impaired polarization of AQP4 may further impair GS clearance, leading to the accumulation of pathogenic mediators.\" Experimental modulation of this system demonstrates that \"Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis.\" Thus, targeting the upstream STING-dependent inflammatory surge provides a mechanism to prevent the secondary degradation of the glymphatic clearance continuum.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   STING activation is not merely a viral response but a secondary driver of microglial pyroptosis in subarachnoid hemorrhage (Source ID: 42435423).\n*   Manganese overload acts as an atypical trigger for cellular senescence through STING-related signaling (Source ID: 42468696).\n*   Iron overload in bone infection models links TfR1-mediated ferroptosis to STING-driven pyroptosis (Source ID: 42454062).\n*   Chirality-dependent therapeutic windows exist for STING inhibitors; L-configured homoproline derivatives show superior safety profiles (Source ID: 42470935).\n*   Fibroblasts utilize STING as a metabolic-inflammatory node to regulate osteoclastogenesis during periodontal biofilm exposure (Source ID: 42459658).\n*   Pemetrexed chemotherapy potentiates \u03b3\u03b4 T cell cytotoxicity by activating the ATM-STING-NF-\u03baB axis (Source ID: 42447803).\n*   Dual-targeted nanoparticle systems are capable of simultaneously inducing mtDNA release and ER stress to hyper-activate STING for immunotherapy (Source ID: 42464666).\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The glymphatic system, which contributes to brain fluid exchange and metabolic waste transport, has not been systematically examined in pediatric tic disorders. METHODS: In this case\u2013control study, 86 children with tic disorders (Tourette syndrome, n\u2009=\u200938; chronic tic disorder, n\u2009=\u200931; provisional tic disorder, n\u2009=\u200917) and 82 age- and sex-matched healthy controls underwent clinical assessments, magnetic resonance imaging, and blood sampling. Glymphatic surrogate markers were assessed using diffusion tensor imaging analysis along the perivascular space (DTI-ALPS index) and standardized choroid plexus (CP) volume. Tic severity was evaluated using the Yale Global Tic Severity Scale (YGTSS). Multivariable regression and mediation analyses were performed to examine associations among glymphatic markers, clinical features, and inflammation. RESULTS: Compared with healthy controls, children with tic disorders exhibited a significantly lower DTI-ALPS index and a larger choroid plexus volume (both P\u2009<\u20090.001). The two glymphatic surrogate markers were inversely correlated (r\u2009=\u2009\u2212\u20090.48, P\u2009<\u20090.001). In multivariable logistic regression analyses, both markers remained independently associated with TD, including lower DTI-ALPS index (OR\u2009=\u20091.89, 95% CI: 1.25\u20132.86; P\u2009=\u20090.003) and higher choroid plexus volume (OR\u2009=\u20091.62, 95% CI: 1.10\u20132.40; P\u2009=\u20090.015). Lower DTI-ALPS index and higher choroid plexus volume were consistently associated with greater tic severity across multivariable models (all P\u2009\u2264\u20090.05). Mediation analyses indicated that IL-6 statistically accounted for part of the association between DTI-ALPS index and tic severity (indirect effect\u2009=\u2009\u2212\u20090.13, 95% CI: \u22120.22 to \u2212\u20090.05), accounting for 31.71% of the total effect, while anxiety symptoms demonstrated a smaller exploratory mediation effect (17.02%). CONCLUSIONS: Children with tic disorders exhibit alterations in functional and structural glymphatic surrogate markers associated with tic severity and multiple accompanying clinical and biological phenotypes. Further longitudinal and mechanistic studies are warranted to clarify temporal relationships and underlying biological pathways.",

With age, lymphatic vessels and lymphoid organs undergo structural and functional decline, leading to impaired transport, disrupted immune cell trafficking, and chronic low-grade inflammation. These changes contribute to systemic inflammaging and are increasingly implicated in cardiovascular disease, metabolic dysfunction, and neurodegenerative disorders. In the central nervous system, deterioration of the glymphatic and meningeal lymphatic systems compromises cerebrospinal fluid circulation and the clearance of amyloid-\u03b2, tau, and other metabolites, thereby accelerating cognitive decline. In this review, we examine the molecular and cellular mechanisms that underline lymphatic ageing, including junctional remodeling, extracellular matrix stiffening, altered lymphangiogenic signaling, and endothelial senescence. We critically assess the consequences of lymphatic dysfunction for systemic and brain health, highlighting unresolved controversies such as the extent to which lymphatic changes are primary drivers of pathology, the limitations of rodent models and indirect imaging readouts, and the lack of ageing-resolved single-cell maps in human tissues. Finally, we discuss therapeutic avenues ranging from antioxidant and pro-lymphangiogenic strategies to lifestyle interventions and reconstructive microsurgery. Together these insights position the lymphatic system as a central, yet underexplored, determinant of resilience in ageing and a promising target for future gerotherapeutic interventions.",

This review summarizes emerging evidence across these domains to propose an innovative integrative model: the vicious triad of PD pathogenesis. The idea suggests that inflammatory signals from the gut, alongside pathologic protein aggregates such as misfolded \u03b1-synuclein, may trigger and sustain a central innate immune response. Gut-derived substances are posited to potentially activate the cGAS-STING pathway in the brain, which may instigate chronic interferon-mediated neuroinflammation. This inflammatory condition could, in turn, impair glymphatic clearance by inducing the mislocalization of aquaporin-4 channels on astrocytes. The inability to eliminate cytotoxic waste, such as mitochondrial DNA and \u03b1-synuclein clumps, establishes a continual reservoir of damage-associated molecular patterns. These agonists may then enhance cGAS-STING signaling, potentially creating a self-sustaining, closed-loop pathogenic cycle that could mechanistically link gut dysbiosis, neuroinflammation, and glymphatic dysfunction. While each pairwise interaction within this triad is supported by indicative experimental evidence from human, animal, and cellular studies, direct proof of their triadic causation within a single system remains an unresolved issue requiring thorough confirmation. Moving beyond linear or parallel models, this framework reinterprets PD as a dynamic systems disorder fueled by this feed-forward circuit. The triad model explains the disease's chronic progression, the stereotypical spread of pathology, and its clinical heterogeneity. Crucially, this framework necessitates a paradigm shift from monotherapeutic approaches to combinatorial strategies that simultaneously target all three components: the peripheral trigger (gut), the central immune amplifier (cGAS-STING), and the clearance sink (glymphatics). Promising therapies consistent with this concept include microbiota engineering, STING antagonists, astrocyte manipulation, and sleep therapy. A framework for biomarker-driven, individualized clinical studies aimed at testing this notion is delineated. The vicious triad theory presents a framework for significant disease change in PD by integrating the gut-brain axis, neuroinflammation, and waste clearance into a cohesive pathogenic cycle.",
        "41990523": "ID: 41990523\nTitle: A diffusion MRI-derived perivascular metric related to glymphatic-associated processes in bipolar disorder vulnerability: Multimodal correlates across emotion dysregulation patients and offspring.\nAbstract: Bipolar disorder (BD) is characterized by marked emotion dysregulation and high familial risk. Identifying early biological markers of vulnerability in BD, including unaffected offspring, is critical to improve risk stratification and intervention, and glymphatic-associated processes may contribute to this vulnerability. We examined 237 participants, including 97 patients with emotion dysregulation disorders (EDD; 34 BD, 33 borderline personality disorder [BPD], 30 attention-deficit/hyperactivity disorder [ADHD]), 67 offspring of EDD patients (EDDoff; including 23 BD offspring [BDoff]), and 73 healthy controls (CTRL). All participants underwent clinical assessments, diffusion and resting-state functional MRI, and serum immune and neurotrophic biomarker sampling. Perivascular diffusion was estimated using diffusion tensor imaging analysis along the perivascular space (DTI-ALPS), a diffusion-derived perivascular metric proposed to relate to glymphatic-associated processes, and compared across groups. To explore multimodal correlates of DTI-ALPS, principal component analyses (PCA) were conducted across clinical, biological, and neuroimaging domains. BD patients and BDoff showed significantly reduced DTI-ALPS compared with CTRL, ADHD, and BPD, supporting its potential role as a vulnerability-related imaging feature for BD. By contrast, ADHD and BPD showed comparable or higher DTI-ALPS relative to controls. Across participants, DTI-ALPS was associated with components reflecting white matter integrity and serum immune and neurotrophic markers. Within BD, lower DTI-ALPS correlated with more manic episodes and poorer working memory. Reduced DTI-ALPS may represent a BD-specific vulnerability-related feature, observable in both patients and at-risk offspring, and not shared by other emotion dysregulation disorders. Multimodal associations with white matter, inflammation, and symptoms underscore its relevance for risk stratification in high-risk populations.",
        "42011629": "ID: 42011629\nTitle: Nutritional modulation of the glymphatic system: mechanistic insights and clinical implications.\nAbstract: The glymphatic system is a brain-wide perivascular clearance pathway mediated by aquaporin-4 (AQP4) water channels at astrocytic endfeet and plays a key role in eliminating neurotoxic proteins, including amyloid-\u03b2, tau, and \u03b1-synuclein. Impaired glymphatic function has been implicated in neurodegenerative disorders such as Alzheimer's and Parkinson's diseases. While sleep and physical activity are established modulators of glymphatic activity, the role of nutrition remains less clearly defined. This review summarizes current evidence on how nutritional factors may influence glymphatic-relevant biology and the underlying molecular and physiological mechanisms. Emerging studies suggest that micronutrients, bioactive lipids, and phytochemicals may influence glymphatic-relevant processes by regulating AQP4 expression and polarization, preserving blood-brain barrier integrity, reducing oxidative stress and neuroinflammation, improving cerebrovascular function, and supporting sleep and circadian regulation. In contrast, high-fat diets, excessive alcohol intake, and iron overload are associated with adverse glymphatic-relevant changes, including altered AQP4 regulation and less favorable clearance-related markers. Although mechanistic and preclinical evidence is increasing, large-scale human studies with standardized imaging approaches are still needed to determine whether targeted nutritional strategies can meaningfully alter glymphatic-related biology and whether such changes are accompanied by favorable neuroimaging or clinical outcomes.",
        "42023290": "ID: 42023290\nTitle: Glymphatic System Dysfunction in Epilepsy: Clinical and Translational Perspectives.\nAbstract: Epilepsy has traditionally been viewed as a disorder involving neuronal hyperexcitability and brain network dysfunction. However, growing evidence indicates that recurrent seizures are associated with widespread disturbances in brain homeostasis, including metabolic stress, neuroinflammation, vascular dysregulation, and sleep disruption. These processes extend beyond neurons and involve brain-wide clearance mechanisms that have received limited attention in epilepsy research. The glymphatic system is a specialized pathway that facilitates cerebrospinal fluid-interstitial fluid exchange and promotes the clearance of metabolic waste and neurotoxic solutes from the brain. Glymphatic transport depends on astrocytic aquaporin-4 channels and is strongly modulated by sleep-wake state, which is highly relevant to epilepsy given the close bidirectional relationship between seizures and sleep disturbances. Impaired glymphatic clearance has been linked to protein accumulation, neuroinflammation, and cognitive decline during aging and in neurodegenerative diseases, suggesting that similar mechanisms may contribute to epilepsy-related disease progression. In this review, we summarize current knowledge of glymphatic anatomy and physiology, focusing on advances in neuroimaging. We then synthesize emerging evidence demonstrating glymphatic dysfunction across multiple epilepsy syndromes. We discuss the clinical implications of impaired cerebral waste clearance for disease burden, treatment outcomes, and cognitive dysfunction and highlight potential therapeutic strategies aimed at modulating glymphatic function. Finally, we address the ongoing debates regarding glymphatic mechanisms, imaging biomarkers, and causal relationships in epilepsy. Collectively, the available data suggest that glymphatic system dysfunction represents a system-level abnormality in epilepsy, offering a complementary framework that integrates the metabolic, vascular, and sleep-related aspects of epileptic brain dysfunction.",
        "42032717": "ID: 42032717\nTitle: Glymphatic dysfunction contributes to thalamic iron retention and secondary thalamic injury after stroke: evidence from primates and rodents.\nAbstract: BACKGROUND: Secondary neurodegeneration, characterized by neuronal loss and neuroinflammation, in the remote thalamus is associated with post-stroke cognitive impairment (PSCI). This study aimed to elucidate common pathological mechanism of the secondary neurodegeneration in both primates and rodents. METHODS: Thalamic amyloid-\u03b2 (A\u03b2), iron deposition and glymphatic dysfunction was assessed across primate and rodent stroke models in different time points, using histopathological, and magnetic resonance imaging methods. Proteomic analysis was performed to explore the molecular mechanisms underlying the secondary thalamic damage. Neuronal loss and neuroinflammation were assessed through histopathological methods. Using aquaporin-4 (AQP4) inhibitor, we investigated whether glymphatic inhibition aggravated thalamic iron deposition and PSCI. RESULTS: A\u03b2 accumulated in the remote thalamus of mice but was absent in cynomolgus monkeys by imaging and histology, and A\u03b240/42 remained unchanged in plasma and cerebrospinal fluid in monkeys following stroke. Instead, quantitative susceptibility mapping MRI and Prussian blue staining uncovered progressive iron deposition in the remote thalamus shared by both species, alongside ferroptosis activation. Glymphatic imaging and AQP4 analyses showed impaired glymphatic clearance and loss of AQP4 perivascular polarization, which worsened along with time. Both stroke monkeys and mice exhibited neuronal injury and increased neuroinflammation in the remote thalamus, with cognitive impairment. Glymphatic inhibition with TGN-020 exacerbated iron deposition and ferroptosis, leading to more severe neuronal loss and microglial proliferation, ultimately aggravating PSCI. In addition, CD31 and ZO-1 co-immunostaining demonstrated blood-brain-barrier damage, with reduced ZO-1 colocalization with CD31. CONCLUSIONS: Iron deposition and ferroptosis-related changes were consistently observed in the remote thalamus across both rodent and primate models, whereas A\u03b2 accumulation appeared to be species-dependent. Glymphatic dysfunction and blood-brain barrier damage in the remote thalamus may jointly facilitates iron accumulation and ferroptosis.",
        "42072737": "ID: 42072737\nTitle: Brain Lymphatic Dysfunction in Subarachnoid Hemorrhage: Pathophysiology and Clinical Implications.\nAbstract: Aneurysmal subarachnoid hemorrhage (SAH) remains a devastating cerebrovascular disorder with high morbidity and mortality, despite advances in aneurysm securing and neurocritical care. Clinical outcomes are determined by early brain injury (EBI), delayed cerebral ischemia (DCI), hydrocephalus, and long-term cognitive impairment, extending beyond the traditional focus on large-vessel vasospasm alone. Emerging evidence identifies the dysfunction of the glymphatic system and meningeal lymphatic pathway, the brain's primary clearance pathways, as a central and unifying mechanism linking acute hemorrhagic injury to delayed and chronic neurological sequelae. Following SAH, acute intracranial pressure elevation, subarachnoid blood clot burden, loss of arterial pulsatility, venous congestion, astrocytic aquaporin-4 perivascular depolarization, and neuroinflammation converge to suppress cerebrospinal fluid-interstitial fluid exchange and outflow in glymphatic system and subsequent meningeal lymphatic drainage. Persistent clearance failure promotes the retention of blood breakdown products, inflammatory mediators, and metabolic waste, amplifying microvascular dysfunction, cortical spreading depolarizations, blood-brain barrier disruption, and secondary ischemic injury. Importantly, accumulating data highlight venous pathology and meningeal lymphatic impairment as critical, yet underappreciated, contributors to delayed injury and post-SAH hydrocephalus. In this review, we synthesize the current knowledge of the physiological organization of glymphatic and meningeal lymphatic systems, delineate the mechanistic and molecular drivers of their dysfunction after SAH, and discuss clinical implications for EBI, DCI, hydrocephalus, and long-term cognitive outcomes. We further outline future directions, including translational imaging, biomarker development, and therapeutic strategies targeting clearance pathways, to advance disease-modifying approaches in SAH.",
        "42079631": "ID: 42079631\nTitle: Neurosurgery as an immune anchor point: a translational framework for perioperative immunoengineering.\nAbstract: Neurosurgical diseases-including brain tumors, hemorrhage/trauma, ischemia, infection, epilepsy, and spinal cord injury-share convergent neuro-immune mechanisms. In the acute phase, sterile inflammation and barrier disruption trigger innate immune cascades. During the subacute phase, immune resolution and clearance determine the quality of tissue repair. In the chronic phase, persistent immune-glia interactions and synaptic remodeling influence epileptogenesis and long-term cognitive outcomes. Recent discoveries-such as the meningeal immune niche, meningeal lymphatic system, and glymphatic clearance pathways-have redefined the classical concept of \"CNS immune privilege.\" The central nervous system is no longer viewed as immune-isolated, but rather as a compartment whose immunity can be directly modulated by surgical intervention and perioperative management. This review proposes a conceptual framework in which neurosurgery serves as a programmable \"immune anchor point.\" By integrating knowledge of neuro-immune interface architecture and temporal dynamics, we establish a closed-loop model encompassing structural pathways, immune dynamics, delivery/timing, and efficacy/toxicity. This paradigm shift aims to accelerate breakthroughs in CNS immunotherapies. The article unfolds along three main themes: (1) the structural foundations of neuro-immune communication-including barrier systems, the meningeal immune niche, and meningeal lymphatic-glymphatic coupling; (2) temporal immune dynamics across acute, subacute, and chronic phases, and their roles in edema, secondary injury, and failed resolution; and (3) the brain tumor immune microenvironment, with a focus on surgical synergy and analysis of why immunotherapies (checkpoint inhibitors, vaccines, oncolytic viruses, cell therapies) have largely failed in glioblastoma. Finally, we propose a translational roadmap integrating perioperative immune management, spatial omics stratification, and local immunoengineering.",
        "42094008": "ID: 42094008\nTitle: Glymphatic-meningeal lymphatic system imbalance: a peripheral-to-central inflammatory bridge in perioperative neurocognitive disorders.\nAbstract: Perioperative neurocognitive disorders (PNDs) are common postoperative complications, particularly in elderly patients. While surgical trauma is known to trigger systemic inflammation, the mechanisms linking peripheral immune activation to perioperative neurocognitive dysfunction remain not fully elucidated. The glymphatic-meningeal lymphatic system is crucial for maintaining homeostasis because it facilitates the exchange of cerebrospinal fluid and interstitial fluid, clears metabolic waste, and eliminates immune mediators. Recent studies have indicated that dysfunction of this clearance axis may contribute to the exacerbation of PNDs. This article explores how perioperative inflammation may influence the glymphatic-meningeal lymphatic system, thereby promoting neuroinflammation. We propose that the interplay between the inflammatory burden and the clearance capacity of the brain is a critical factor in the pathogenesis of PNDs. Through multimodal approaches-integrating advanced imaging techniques, high-dimensional immunogenomic profiling, biofluid biomarkers, and neurophysiological monitoring-we can more comprehensively characterize alterations in glymphatic-meningeal lymphatic function and their interactions with microcirculatory and immune dynamics. Furthermore, we discuss potential therapeutic strategies targeting the glymphatic-meningeal lymphatic system, which could offer clinical insights for the prevention and treatment of PNDs by targeting the underlying mechanisms.",
        "42107812": "ID: 42107812\nTitle: Role of AQP4 mediated glymphatic system dysfunction in postoperative neuroinflammation and cognitive dysfunction.\nAbstract: Postoperative cognitive dysfunction (POCD) is a common complication in surgical patients, particularly those with pre-existing chronic inflammation. Although impaired glymphatic clearance, a brain waste drainage system dependent on astrocytic aquaporin-4 (AQP4) polarization, is implicated in neurodegenerative disorders, its role in POCD pathogenesis and interaction with neuroinflammation remains unknown. Here, we investigated whetherglymphatic dysfunctiondrives postoperative neuroinflammation and cognitive deficits using a \"dual-hit inflammation\"model.Our results revealed glymphatic influx/efflux was severely impaired, reaching its lowest point 24\u00a0h postoperatively, and gradually recovered by day 7, preceding peak neuroinflammation. AQP4 depolarization correlated with glymphatic dysfunction. Pharmacological AQP4 inhibition (TGN-020)exacerbated glymphatic dysfunction, prolonged cytokine accumulation, and worsened cognitive deficits. HippocampalAQP4 overexpression restored glymphatic clearance, reduced neuroinflammation, and rescued cognition. These findings establish AQP4-mediated glymphatic impairment as an upstream driver of neuroinflammation in POCD, revealing a novel therapeutic target for high-risk surgical patients.",
        "42134763": "ID: 42134763\nTitle: The Glymphatic system: A dynamic regulator of brain health and therapeutic target.\nAbstract: The central nervous system (CNS) maintains homeostasis despite high metabolic activity and the apparent absence of conventional lymphatic vessels within the parenchyma. The identification of the glymphatic system-a glial-dependent perivascular network-proposes a mechanistic framework for interstitial waste clearance. This review presents a systems-level framework that views the glymphatic network as a dynamic regulator of brain homeostasis, essential for neurophysiological stability. We examine the biophysical determinants of solute transport, emphasizing the critical role of polarized aquaporin-4 (AQP4) channels and navigating the ongoing scientific debate regarding the relative contributions of convective bulk flow versus diffusion. We further analyze central regulation of clearance efficiency by the sleep-wake cycle, circadian rhythms, and state-dependent interstitial ionic fluctuations. Pathologically, we consider glymphatic dysfunction as a convergent mechanism across diverse disorders, potentially contributing to proteostasis failure in neurodegeneration, exacerbating secondary injury after stroke and trauma, linking systemic metabolic conditions to CNS impairment, and presenting emerging evidence for its role in major psychiatric disorders, including depression, bipolar disorder, and schizophrenia. Finally, we evaluate strategies to restore clearance capacity through lifestyle and pharmacological interventions; the translational potential of leveraging perivascular pathways for CNS drug delivery; and the need for developing non-invasive imaging biomarkers to enable preventative neurology. Unlike previous reviews that have largely summarized the system's anatomy and physiology, we integrate three underappreciated dimensions: (i) state-dependent neurobiological control by sleep and circadian timing; (ii) glymphatic failure as a shared systems-level mechanism across acute and chronic neurological and psychiatric disorders; and (iii) the dual translational relevance of the perivascular pathway as both a therapeutic target and a drug-delivery route.",

This multifactorial neurodegenerative disorder is characterized by amyloid-\u03b2 aggregation, tau hyperphosphorylation, and neuroinflammation. The lack of effective disease-modifying therapies highlights the urgent need for multi-target strategies. Epimedium brevicornu flavonoids (EF), derived from a traditional medicinal plant used to support cognitive function, exhibit significant neuroprotective potential; however, the underlying mechanisms remain to be fully elucidated. To investigate the neuroprotective effects and underlying mechanisms of EF against lipopolysaccharide (LPS)-induced neuroinflammation and Alzheimer's disease-related pathology. EF were extracted and quantitatively analyzed. Mice were pretreated with EF for 14 days before LPS injection (1.0 mg/kg). Behavioral performance was assessed using the Open field, Y-maze, and Morris water maze tests. EF components in extract, serum, and brain were characterized by UHPLC-QTOF-MS/MS. Network pharmacology and molecular docking were employed to predict active compounds, targets, and signaling pathways. ELISA, Western blot, and immunofluorescence were conducted to evaluate cytokine levels, microglial and astrocytic activation, A\u03b242 deposition, tau phosphorylation, and NeuN+ neuronal density. The involvement of PI3K/AKT and cGAS-STING pathways was further validated. In BV2 microglia, NO release and iNOS/Iba1 as well as CD206/Iba1 expression were examined to verify anti-inflammatory effects of EF in vitro. A total of 127 components in EF were identified, among which 45 and 38 were detected in serum and brain, respectively. The key compounds showed favorable target binding (<-6.2 kcal/mol). EF markedly improved cognition performance in LPS-treated mice, suppressed systemic inflammation and neuroinflammation, inhibited glial activation, reduced APP/BACE1/A\u03b242 expression and tau phosphorylation, and preserved neuronal integrity. Mechanistically, EF inhibited PI3K/AKT and cGAS-STING signaling pathways in vivo and promoted M2 polarization in BV2 microglia in vitro. EF confers neuroprotection against LPS-induced cognitive impairment, a process linked to the modulation of neuroinflammation, A\u03b2 generation, and tau phosphorylation, and associated with PI3K/AKT and cGAS-STING signaling pathways. These findings highlight EF as a promising multi-target candidate for mitigating inflammation-driven AD-relevant pathological features.",

This study investigated the association between glymphatic dysfunction, systemic inflammation, and brain volume changes in patients with MDD. Glymphatic function was assessed using the diffusion tensor image analysis along the perivascular space (DTI-ALPS) index in 176 patients with MDD and 178 controls. Inflammatory cytokine levels, including plasma C-reactive protein (CRP) levels, were measured in 68 patients with MDD and 54 controls. Depressive symptoms were evaluated using the Hamilton Depression Rating Scale. Statistical analyses included a multivariate analysis of covariance and Pearson's partial correlations adjusted for covariates. Mediation analysis examined the relationships between CRP, glymphatic function, and brain volume. Patients with MDD showed reduced glymphatic function compared to healthy controls. Reduced DTI-ALPS indices were correlated with higher CRP levels and increased ventricular volumes, including the choroid plexus. CRP levels were negatively correlated with DTI-ALPS indices and right choroid plexus volumes. Mediation analysis indicated that glymphatic dysfunction partially mediated the relationship between elevated CRP levels and decreased choroid plexus volume in patients with MDD. This study found that in MDD, glymphatic dysfunction is associated with higher CRP and mediates the link between systemic inflammation and right choroid plexus volume. Given sample size and limited covariate control, these results are preliminary and need confirmation in larger longitudinal cohorts. Even so, impaired glymphatic function may represent a therapeutic target.",

Anaplastic lymphoma kinase (ALK) has recently emerged as a therapeutic target for inflammatory and immune disorders; however, its role in neuroinflammation and PD remains unclear. In this study, we investigated the role of ALK using the ALK-specific inhibitor lorlatinib (LOR) in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced mouse model of PD. LOR significantly improved motor function, attenuated dopaminergic neuronal loss, and restored neurotrophic factor expression. LOR also suppressed ALK phosphorylation and inhibited activation of the downstream STING-TBK1-IRF3/NF-\u03baB signaling pathway in the SN. Notably, MPTP-induced p-ALK expression was predominantly colocalized with microglia, suggesting a potential role for microglial ALK in PD-related neuroinflammation. LOR consistently reduced microglial and astrocytic activation, decreased pro-inflammatory cytokine expression, and attenuated oxidative stress by activating the Nrf2 antioxidant signaling pathway. Additionally, LOR restored the blood-brain barrier integrity and suppressed T lymphocyte infiltration into the SN region. Finally, LOR attenuated the MPTP-induced apoptosis and necroptotic cell death in dopaminergic neurons. Collectively, these findings demonstrate that ALK inhibition confers neuroprotection by modulating microglia-mediated neuroinflammation. Given that LOR is a clinically approved anticancer drug with blood-brain barrier permeability, this study provides experimental evidence supporting its repositioning for the treatment of neuroinflammatory disorders, such as PD.",

Standard tracer injection approaches may not reflect endogenous efflux. Here, we develop a non-invasive genetic system to trace neuron-derived protein clearance from the brain to cerebrospinal fluid (CSF) and border tissues. We identify distinct drainage routes and border hotspots missed by tracer injection, confirmed by bioorthogonal labeling of endogenous neuronal proteins. Pulse-chase kinetics reveal slow skull outflow versus rapid dural and nasal clearance. Transcriptomic analyses uncover border cells sampling neuronal antigens, including tolerogenic skull-resident B cells. Region-restricted reporter expression demonstrates compartmentalized clearance following a \"nearest exit\" principle, where anatomical origin dictates drainage pathway. Disease disrupts clearance through distinct mechanisms: inflammation drives vascular leakage into blood, while amyloid pathology causes parenchymal retention and border exit obstruction. These findings define brain clearance as a compartmentalized system of organized pathways and immune niches whose dysfunction may underlie regional vulnerability in neurological disease.",

Its pathogenesis involves oxidative stress, inflammatory responses, and dysfunction of the spinal cord glymphatic system. This study aimed to investigate the protective effects of Ginkgolide B (GB) in alleviating PDN, with a particular focus on its roles in modulating the gut microbiota and enhancing glymphatic function in the spinal cord. A PDN model was established in male Sprague-Dawley rats to evaluate the therapeutic effects of GB. GB was administered to assess its impact on gut microbiota composition, intestinal barrier integrity, and inflammation in both the intestine and spinal cord. Additionally, the effect of GB on aquaporin-4 (AQP4) polarization in the spinal cord glymphatic system was examined to determine its role in facilitating the clearance of inflammatory mediators. GB treatment significantly alleviated hallmark features of PDN, including neuropathic pain and spinal cord inflammation. It modulated the gut microbiota, restored intestinal barrier function, and reduced intestinal inflammation. Moreover, GB reestablished AQP4 polarity in the spinal cord, thereby enhancing glymphatic function and promoting the clearance of inflammatory mediators, which contributed to reduced neuroinflammation. These findings suggest that Ginkgolide B may represent a multifaceted therapeutic strategy for PDN. By regulating the microbiota-gut-spinal cord glymphatic axis, improving glymphatic function, and alleviating PDN symptoms, GB shows promise as a novel treatment targeting both metabolic and neuroinflammatory components of the disease.",

In a cuprizone (CPZ)-induced demyelination mouse model, proteomic analysis revealed the significant downregulation of a myelin basic protein-derived peptide (sequence: DTGILDSIGRFFS), which we have designated as NSDP1 (nervous system-derived peptide 1). In vitro, NSDP1 suppressed LPS-induced microglial activation in BV2 cells, reducing reactive oxygen species (ROS) production, downregulating pro-inflammatory markers (iNOS, TNF-\u03b1, IL-1\u03b2), and upregulating the expression of anti-inflammatory marker Arg-1. In vivo, NSDP1 administration via intracerebroventricular injection significantly mitigated CPZ-induced weight loss and demyelination in the corpus callosum. NSDP1 attenuated CPZ-induced demyelination, restoring expression of myelin proteins (MAG, MOG), increasing oligodendrocyte precursor cell (OPC) density, improving myelin sheath ultrastructure, and enhancing axonal myelination efficiency. Furthermore, NSDP1 attenuated CPZ-induced reactive gliosis, reducing both microglial activation and astrocytic reactivity in the corpus callosum. RNA sequencing revealed that NSDP1 modulated myelination-related pathways and correlated with improved locomotor recovery. Mechanistically, NSDP1 exerted its anti-inflammatory effects by inhibiting the cGAS-STING signaling pathway, as shown by reduced cGAS and STING expression in LPS-stimulated BV2 cells. The effects of NSDP1 on ROS and pro-inflammatory cytokine release were reversed by the STING activator DMX and mimicked by the STING inhibitor SN-011. Collectively, these findings identify NSDP1 as a downregulated myelin-derived peptide with potent therapeutic potential, which attenuates demyelination and suppresses neuroinflammation in demyelinating diseases by inhibiting the cGAS-STING pathway.",

Current therapies targeting A\u03b2 plaques and hyperphosphorylated Tau show limited efficacy. The core pathology of AD involves neuroglial metabolic network collapse, which is tightly associated with brain iron dyshomeostasis and abnormal ferroptosis. As the main iron storage and antioxidant cells in the CNS, astrocytes transform into disease-associated astrocytes under AD conditions. Metabolic reprogramming switches them from a neuroprotective to a pro-ferroptotic phenotype, contributing to thereby exacerbating systemic metabolic dyshomeostasis. This review systematically elaborates the regulatory mechanisms of astrocytic ferroptosis in AD: disordered iron metabolism (e.g., aberrant DMT1/FPN1 expression) induces iron accumulation as the initiation prerequisite; excessive oxidative stress (Ang II/HIF-1\u03b1-NOX4 axis-mediated ROS generation) and impaired antioxidant defense (Nrf2-SLC7A11/GPX4 inactivation, ApoE4 dysfunction) serve as core regulatory modules; FTH1 and SAT1 dysregulation elevates the labile iron pool, while AQP4 dysfunction impairs metabolite clearance, amplifying ferroptosis. Moreover, aberrant crosstalk among astrocytes, microglia and oligodendrocytes exacerbates AD-related neurodegeneration. Collectively, astrocytic ferroptosis acts as a key integrative mechanism linking iron dysmetabolism, oxidative stress, neuroinflammation and A\u03b2/Tau pathology, offering a potential new avenue for decoding AD pathogenesis. Targeting astrocytic ferroptosis is expected to overcome the long-standing therapeutic limitations of conventional AD treatments, providing theoretical support and new directions for developing disease-modifying AD therapies. While individual components including disease-associated astrocytes, brain iron dyshomeostasis, NOX4- and NRF2-related ferroptosis have been documented separately, this review represents the first comprehensive synthesis that identifies astrocytic ferroptosis as a central hub that unifies these fragmented mechanisms into a cohesive pathogenic cascade driving AD.",

Utilizing 14 Huntington's disease cases (6 females and 8 males; age range 41-72) split into mood, motor and mixed symptomatology and nine control cases (3 females and 6 males; age range 53-72), we used mRNA sequencing to examine the midcingulate cortex transcriptome in Huntington's disease and NanoString analysis to validate the differentially expressed transcripts. These genes underwent bioanalysis, including gene ontology enrichment, protein-protein interaction and cell-type enrichment analysis. Here we show that multiple neuroinflammatory transcripts are overexpressed in the Huntington's disease midcingulate cortex, such as those linked to classical complement, toll-like receptor signaling and AQP4 activity. However, related processes, such as chemokine activity, are downregulated, implying that a complex combination of gain and loss of neuroinflammatory function is occurring. In summary, neuroinflammation-related transcripts are overrepresented in Huntington's disease cases with motor symptoms compared to mood and mixed. These findings suggest a potentially unique role for the midcingulate cortex in motor-specific neuroinflammatory pathophysiology. Huntington\u2019s disease (HD) is an inherited disease that causes the progressive breakdown of nerve cells in the brain. HD has a broad impact on a person\u2019s functional abilities and results in mood, movement, thinking, and psychiatric problems. The midcingulate cortex (MCC) is a brain region that is impacted by HD pathology. Our project examined whether the degree of the immune system\u2019s response, called inflammation, in the MCC correlates with the type of symptoms. We demonstrate that neuroinflammation-related gene products are increased in HD cases with motor symptoms compared to those with mood and mixed symptoms. These findings suggest a potentially unique role for the MCC in motor-specific neuroinflammatory pathology.",
        "42253262": "ID: 42253262\nTitle: Reviving Brain Waste Clearance: A Pharmacological Perspective on Glymphatic Dysfunction and AQP4 Modulation.\nAbstract: The glymphatic system is a brain-wide clearance pathway that maintains CNS homeostasis by eliminating interstitial solutes, including neurotoxic proteins such as amyloid-\u00df and tau. This process depends on CSF movement through perivascular spaces, where it exchanges with ISF before draining via perivenous routes. Aquaporin-4 (AQP4) fluid channels localized at astrocytic endfeet are central to glymphatic transport, with their polarization being critical for efficiency. Glymphatic activity peaks during sleep but declines with aging, vascular stiffening, and neuroinflammation. Impaired clearance has been linked to the progression of neurodegeneration. Dysregulation of signaling pathways, including NF-kB, Nrf2/keap1, and NLRP3 inflammasome, contributes to AQP4 mislocalization, glial activation, and disrupted fluid dynamics. These alterations promote neuroinflammation and oxidative stress, accelerating neurodegeneration. Pharmacological interventions that restore AQP4 polarization, together with antioxidant and anti-inflammatory therapies, have demonstrated potential in enhancing glymphatic clearance. In addition, recent advances in imaging and drug delivery technologies, such as nanocarriers and non-invasive nose-to-brain systems, provide new opportunities to modulate glymphatic function and improve neuroprotection. However, significant challenges remain in achieving isoform-selective AQP4 modulation, ensuring long-term safety, and translating findings from rodent models to humans. Overall, targeting AQP4 and associated molecular pathways represents a promising adjunctive strategy to enhance waste removal, reduce neuroinflammation, and delay neurodegenerative disease progression.",
        "42264871": "ID: 42264871\nTitle: Concussion pathophysiology: From biomechanical insult to clinical phenotype - or is injury truly the beginning?\nAbstract: Mild traumatic brain injury (mTBI) is associated with substantial morbidity worldwide. Emerging evidence demonstrates that both impact- and blast-related mTBI produce diffuse microstructural and functional alterations, e.g., diffuse axonal injury, astroglial and microglial activation, cerebrovascular dysfunction, and neurometabolic disturbance. Rotational acceleration in impact injury preferentially induces white matter shear. Blast overpressure exerts prominent effects at cerebrovascular interfaces, particularly within perivascular spaces (PVS). These biomechanical differences may yield distinct early injury phenotypes but converge on shared downstream cascades involving ionic disequilibrium, excitotoxicity, mitochondrial dysfunction, inflammation, and impaired cerebral blood flow regulation. The glymphatic system has emerged as a potential mechanistic bridge between acute injury and chronic symptomatology. Experimental and clinical studies demonstrate altered aquaporin-4 polarization, increased PVS burden, impaired solute clearance, elevated inflammatory markers, and tau pathology following mTBI. Increased PVS burden has been linked to persistent cognitive deficits and overall post-concussive symptom burden, suggesting a role of glymphatic dysfunction in long-term outcomes. However, biomarker-phenotype correlations remain modest across cognitive, headache, sleep, and affective domains. In this review, we summarize the existing evidence for biological alterations following mTBI and discuss a systems-based framework in which mTBI functions as a \"second hit,\" destabilizing neural networks with variable pre-injury vulnerability. Under this model, chronic phenotypes may reflect interactions between injury-induced pathophysiology and host-specific risk factors, rather than direct linear effects of tissue damage alone. Integrating advanced neuroimaging, molecular biomarkers, and longitudinal phenotyping may clarify mechanistic pathways and inform targeted resilience-building interventions.",

While often idiopathic, ON is increasingly recognized in association with immune-mediated triggers, including post-vaccination phenomena. The proposed pathophysiology involves molecular mimicry, where vaccine-induced antigens trigger a cross-reactive immune response against myelin basic protein. Distinguishing vaccine-associated ON from primary demyelinating diseases, such as Multiple Sclerosis (MS) or Neuromyelitis Optica Spectrum Disorder (NMOSD), poses as significant diagnostic challenge, particularly in adolescents. Prompt differentiation is essential to guide clinical management and therapeutic interventions. We report a case of a previously healthy 15-year-old female who presented with a two week history of painful visual loss in the right eye, occurring seven days after quadrivalent HPV vaccination. Examination revealed marked asymmetry in visual acuity and a right-sided relative afferent pupillary defect (RAPD). Other cranial nerves (III-XII), motor, sensory, and cerebellar examinations were unremarkable; no papilledema was noted. Laboratory investigations and cerebrospinal fluid (CSF) analysis were normal, except for mild microcytic anemia. MRI of the brain, orbits, and spine demonstrated bilateral optic nerve and perineural enhancement without evidence of demyelinating plaques, confirming bilateral optic neuritis. Autoimmune serology and metabolic panels (ANA, B12, folate, zinc) were within normal limits; serum AQP4-IgG and MOG-IgG were not available at the time of writing the report. The patient received five days of intravenous methylprednisolone, resulting in substantial visual recovery at follow-up. This case demonstrates the diagnostic complexity of optic neuritis in adolescents and highlights the necessity of maintaining a high index of clinical suspicion for vaccine-associated immune-mediated events. Although bilateral optic neuritis temporally associated with vaccination is rare and the precise pathophysiological link remains a subject of ongoing debate, a thorough assessment of the clinical chronology and temporal relationship to immunization can facilitate a prompt diagnosis. Timely intervention with corticosteroids is essential to mitigate progression and prevent permanent visual sequelae. However, long-term longitudinal surveillance is mandatory to distinguish such monophasic episodes from the initial manifestation of a chronic demyelinating disease.",

Mediated by polarized aquaporin-4 (AQP4) channels on astrocytic end-feet, this macroscopic system drives the convective exchange of cerebrospinal fluid (CSF) and interstitial fluid (ISF), establishing a functional coupling between the central nervous system (CNS) and the adaptive immune system. Emerging evidence highlights that glymphatic dysfunction act as both a consequence and a driver of numerous neurological disorders. Neurological pathologies, including neuroinflammation and gliovascular remodeling, compromise the structural and functional integrity of glymphatic architectures. Conversely, glymphatic dysfunction exacerbates neurotoxic wastes accumulation, accelerates disease progression, and perpetuates a pathological positive-feedback loop. Despite growing recognition of this bidirectional relationship, the precise mechanisms remain incompletely understood, and targeted therapeutic strategies are still lacking. In this review, we map the functional architecture of this pathway, from periarteriolar CSF influx to perivenous efflux, and dissect its dependence on critical modulators including sleep-wake rhythms, arterial pulsatility, and aging. Furthermore, we explore novel therapeutic interventions, ranging from AQP4-targeted pharmacological modulation to non-invasive physical approaches, and evaluate their potential to shift clinical paradigms from symptomatic management to disease modification.",

AQP4-knockout mice were immunized with the AQP4-derived peptide to generate AQP4-reactive Tfh and Th17 cells. These cells were subsequently isolated and adoptively transferred into wild-type recipient mice. At disease peak-defined by consistent neurological deficits-spinal cord and brain tissues were harvested for histopathological analysis, as well as immunohistochemistry. Central nervous system immune cell infiltration was quantified via flow cytometry. Total RNA was extracted from spinal cord tissue for bulk RNA sequencing; differentially expressed genes were validated using quantitative real-time PCR. Recipient mice that received AQP4-reactive Tfh or Th17 cells developed progressive hind-limb weakness, with Th17-transferred mice exhibiting significantly more severe clinical scores. Histopathological analyses revealed robust perivascular inflammation, parenchymal immune infiltration, and focal demyelination. Immunohistochemical quantification demonstrated significantly increased the optical density of CD3, B220, GFAP, IBA1, and CXCL9, alongside markedly decreased MBP expression. Flow cytometric profiling confirmed substantial infiltration of leukocytes and activated microglia/macrophages into the central nervous system (CNS). Transcriptomic analysis identified CXCL9 as one of the most upregulated chemokines in the spinal cord; its astrocytic origin was further corroborated by confocal immunofluorescence co-localization with GFAP. Our findings establish that AQP4-specific Tfh and Th17 cells are sufficient to drive key neuropathological features of NMOSD-including microglial reactivity, leukocyte recruitment, neuroinflammation, and demyelination-in vivo. The pronounced upregulation and astrocyte-derived expression of CXCL9 suggest its involvement in orchestrating CNS inflammation and position it as a potential contributor for NMOSD.",

Central to this process is the mammalian target of rapamycin complex 1 (mTORC1), a convergent integrator regulator of metabolism that integrates nutrient sensing with cellular growth. While essential for development, chronic mTORC1 hyperactivity, termed mTORopathy, emerges during aging, driving a deleterious cycle of mitochondrial dysfunction, neuroinflammation, and impaired protein clearance. This pathological state promotes the accumulation of toxic proteins, such as amyloid-beta, tau, and alpha-synuclein, while simultaneously suppressing autophagy and glymphatic function. Furthermore, mTORC1 overactivation in glial cells fuels inflammaging by inducing cellular senescence and the senescence-associated secretory phenotype (SASP), which compromises blood-brain barrier integrity and synaptic plasticity. Conversely, pharmacological inhibition of mTORC1 using rapamycin or its analogs (rapalogs) has demonstrated significant neuroprotective potential. By restoring autophagic flux, rebalancing metabolic axes (AMPK/SIRT1), and suppressing chronic inflammation, these compounds can rescue synaptic function and reactivate neurogenesis. This review synthesizes current evidence regarding mTORC1 as a convergent integrator for brain aging and evaluates the clinical prospects of mTOR-targeted therapies in mitigating neurodegenerative decline.",

Their true prevalence in Germany is unknown and can only be estimated from heterogeneous international data. Assuming 1-3 cases per 100,000 people for each disease suggests several thousand affected individuals nationwide, yet the German Neuromyelitis Optica Study Group (NEMOS) registry currently holds records of only about 1,300 patients seen in specialised centres. Numbers and care structures outside such facilities remain largely unknown. This survey aimed to assess the current state of NMOSD and MOGAD care in Germany, identify gaps, and inform future care strategies. An online questionnaire aimed at neurologists and neuropaediatricians was distributed via NEMOS, the German Neurological Society (DGN), the Professional Association of German Neurologists (BVDN), and the German Network for Research on Autoimmune Encephalitis (GENERATE) from March to May 2025. Questions addressed care structures, diagnostics, coding, treatment, guideline use, and practitioners' needs. A total of 104 physicians from all German federal states participated. Half worked in university hospitals, the remainder in other clinics and outpatient settings. Most were specialised in neuroimmunology (70.2%). Many reported an increase in patient numbers for NMOSD (55.8%) and MOGAD (77.4%). Diagnostic practices revealed significant inconsistencies: almost half of the respondents were unaware of their referral laboratory's antibody assays, and ELISA remained in use despite clear recommendations for cell-based assays. ICD-10 coding varied widely. Off-label rituximab was most frequently used for first-line therapy of AQP4-antibody-positive NMOSD (69.6%), compared to satralizumab (57.1%), ravulizumab (55.4%) and inebilizumab (50.0%). AQP4-antibody-negative NMOSD was mainly treated with rituximab (87.0%). Also in MOGAD, rituximab was frequently used (by 58.9%), yet paediatricians preferred glucocorticoids and intravenous immunoglobulins. 69.6% initiated treatment for MOGAD after the first attack. Notably, 41.8% of physicians reported untreated NMOSD and 64.6% untreated MOGAD patients. Most respondents relied on national guidelines; 43.2% expressed a need for further education and patient information. Our findings highlight substantial heterogeneity in the diagnosis and treatment of NMOSD and MOGAD in Germany with potential implications for patient outcomes. This underscores the need for harmonised procedures and targeted educational resources to improve diagnostic reliability, treatment equity, and overall quality of care.",

It is characterized by motor and cognitive impairments. However, the mechanisms underlying individual susceptibility to FXTAS among carriers remain poorly understood. Emerging evidence suggests that neuroinflammation and glymphatic dysfunction may interact and play key roles in the pathological cascade leading to neurodegeneration. This study aimed to investigate potential glymphatic and/or inflammatory dysfunction in FMR1 premutation carriers with FXTAS using the diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) index, as well as gene expression and functional enrichment analyses in individuals with FXTAS versus controls. We analyzed the DTI-ALPS index in 14 participants with FXTAS and 25 age- and sex-matched controls, and assessed the expression and pathway dysregulation of genes related to neuroinflammation and glymphatic function using Reactome analysis in postmortem brain tissue from 3 individuals with FXTAS and 12 controls and skin fibroblasts from 6 individuals with FXTAS and 3 controls. The DTI-ALPS index was significantly lower in individuals with FXTAS compared to controls in the right but not left hemisphere (p\u202f=\u202f0.0051) and globally in both hemispheres (p\u202f=\u202f0.0473). There was no correlation between lower DTI-ALPS index and increasing CGG repeat length but a trend was observed in males. Reactome analysis revealed downregulation of aquaporin-mediated transport in brain tissue and fibroblasts, upregulation of multiple immune-related and inflammatory pathways, predominantly in brain tissue, and increased circadian-related pathway activity in fibroblasts. Our findings point at glymphatic system dysfunction and neuroinflammation in FXTAS pathophysiology, as evidenced by in vivo DTI-ALPS metrics and gene pathway dysregulation and expression in fibroblasts and in postmortem FXTAS brains.",

However, the combined neurotoxic effects of Pb and HTN, particularly in terms of mood disorders such as anxiety and depression, remain poorly understood. Herein, using a combined exposure model, we found co-exposure to Pb and HTN markedly aggravates anxiety- and depression-like behaviors in mice compared with Pb and HTN exposure alone. The prefrontal cortex was identified as the most vulnerable brain region, with astrocytes as the most susceptible cell type to senescence. Notably, treatment with dasatinib and quercetin, a senolytic regimen that selectively eliminates senescent cells, significantly alleviated the behavioral deficits induced by Pb and HTN co-exposure. Further investigation revealed Pb and angiotensin II (AngII) co-exposure promoted phase separation of cyclic GMP-AMP synthase (cGAS), a key DNA sensor. Pharmacological disruption of biomolecular condensates with 1,6-hexanediol (1,6-HD) partially rescued astrocyte senescence induced by Pb and AngII co-exposure. Inhibition of mitochondrial DNA (mtDNA) replication with ethidium bromide (EtBr) markedly reduced cytosolic mtDNA accumulation caused by co-exposure, suppressed cGAS phase separation, and downregulated the expression of senescence-associated proteins including P16, P211, \u03b3H2AX, and SASP. These findings uncover a previously unrecognized role of mtDNA-dependent cGAS phase separation in driving astrocyte senescence and environment-related neuropsychiatric dysfunction, and highlight cGAS phase separation as a promising therapeutic target for preventing anxiety and depression in individuals simultaneously exposed to Pb and HTN.",

Treatment has evolved from broad immunosuppressants to targeted biologics, such as complement inhibitors (ravulizumab/eculizumab), supported by strong evidence, including the CHAMPION-NMOSD trial for ravulizumab in AQP4-Ab+ve NMOSD patients. This case highlights the importance of prompt diagnosis and innovative treatment approaches in the management of NMOSD. A 20-year-old woman presented with acute brainstem dysfunction (dysarthria, diplopia) and a 1-month history of area postrema syndrome (APS), progressing to dysphagia and dyspnea requiring ICU admission. Diagnostic workup revealed AQP4-IgG+ NMOSD with characteristic lesions in the area postrema, pons, and cervical cord (C1-C3). The patient achieved complete clinical recovery with ravulizumab, with near-complete radiological resolution at 3 months and clinical and radiological stability through ~24 months of follow-up, highlighting the efficacy of post-acute initiation of complement inhibition in severe NMOSD.

Although relapse rates have markedly decreased with the emergence of targeted biologics, treatment switches are increasingly encountered due to long-term treatment considerations and adverse events. However, safe switching strategies, especially within 12 months after a relapse, which we defined operationally as the \"cluster phase\", have not been established. We investigated relapse risk and potential preventive strategies when switching from complement inhibitors in AQP4-IgG-positive NMOSD. We retrospectively reviewed patients with AQP4-IgG-positive NMOSD treated at St. Marianna University School of Medicine who underwent at least one biologic switch. Clinical records were assessed for patient characteristics, treatment history, timing of switching, and relapse occurrence. Particular attention was given to switching from complement inhibitors during the cluster phase. Among 14 patients who switched biologics, 5 switched from complement inhibitors, 4 switched between complement inhibitors, 2 between B-cell-depleting therapies, and 3 from IL-6 receptor inhibitors. Six of the 14 switches occurred during the cluster phase, including 3 from complement inhibitors (all to B-cell-depleting agents). One of the two patients switched without bridging therapy during the cluster phase experienced optic neuritis relapse, while no relapses occurred in the other 13 switching cases. This observation suggests a possible vulnerability during the cluster phase, although definitive conclusions cannot be drawn due to the small sample size. Switching from complement inhibitors during the cluster phase may be associated with an increased susceptibility to relapse. Bridging strategies, such as plasma exchange or temporary biologic overlap, may help reduce the likelihood of therapeutic gaps, but these findings remain hypothesis-generating. Clinicians should proactively discuss future switching scenarios and develop long-term treatment plans with patients.",

We report how an expedited genomic diagnosis in conjunction with natural history data can enable a long-term brain-penetrant anti-inflammatory regimen to optimise neurodevelopmental outcomes in genetic autoinflammatory brain disorders. Expedited genomic testing identified compound heterozygous ADAR1 mutations. Published natural history data from 33 patients with biallelic ADAR1 mutations reported severe disability (GMFCS V) or death in 79%. To reduce neuroinflammation, we commenced a long-term pulsed oral dexamethasone protocol (20\u2009mg/m2 for 3\u2009days every 3\u2009weeks) from the age of 11\u2009months, plus ruxolitinib, a Janus Kinase (JAK) inhibitor (5\u2009mg per day). At the age of 24\u2009months, the patient was crawling and walking a few steps unaided, with a GMFCS level of II. Single-cell RNA sequencing of 41\u2009164 leukocytes, taken before and after 3\u2009months of treatment and compared to three age matched male controls, showed a reversal of upregulated pan-cellular interferon pathways, with most differentially expressed genes observed in monocytes. On treatment, there was statistically significant downregulation of key autoinflammatory genes, including nucleic acid sensing (CGAS, IFIH1, SAMHD1), interferon-stimulated genes (ISG15 and IFIF44L) and signalling (JAK1). Given the dual immune therapy, it was not possible to define whether the biological effect was related to dexamethasone or JAK inhibitor, or both. Compared with natural history data, our data suggest that early diagnosis, and the use of early brain-penetrant immune suppressants (dexamethasone), may improve outcomes in ADAR1 AGS.",

Previous work showed that repeated gastrointestinal infection with Citrobacter rodentium can induce PD-like motor dysfunction in Pink1 knockout (KO) mice, along with immune cell infiltration into the brain. To better understand mechanisms underlying immune-mediated brain attack in this model, we tested whether mild infections are sufficient to increase blood-brain barrier (BBB) permeability and trigger brain inflammation. Pink1 wild-type (WT) and KO mice were infected with C. rodentium, and gadolinium-enhanced magnetic resonance imaging (MRI) was performed at days 13 and 26 post-infection to assess BBB integrity. Quantitative MRI analysis revealed increased BBB permeability at day 26 in both WT and KO mice, particularly in the striatum, dentate gyrus, somatosensory cortex, and thalamus. Notably, this permeability was not associated with changes in tight junction protein expression or dopamine system markers in the striatum at either time point. However, persistent microglial activation was observed at day 26 post-infection, along with elevated levels of inflammatory mediators such as eotaxin, IFN-\u03b3, CXCL9, IL-17, and MIP-2 in the striatum. Additionally, serum levels of IL-17 and CXCL1 were increased in infected Pink1 KO mice. Flow cytometry revealed neutrophil infiltration in the brain at day 26 post-infection. Finally, a bulk RNA-seq transcriptome analysis revealed that gene sets related to synaptic function were particularly influenced by the infection and that inflammation-related genes were upregulated by the infection in the Pink1 KO mice. These findings support the hypothesis that even mild gastrointestinal infections can increase BBB permeability, disrupt brain homeostasis, and promote chronic neuroinflammation. In genetically susceptible individuals, such as those with Pink1 deficiency, this may represent a first hit that contributes to subsequent induction of PD pathology with aging.",

Aquaporin-4 (AQP4) has been implicated in HS-induced brain injury, but its role in heat acclimation (HA)-mediated protection remains unclear. This study investigated whether HA ameliorates HS-induced brain damage through AQP4. 9L/lacZ cells were randomly assigned to four groups: Control (37\u202f\u00b0C, 5% CO\u2082), HA (39\u202f\u00b0C, 5% CO\u2082, 2\u202fh/day for 6\u202fdays), HS (43\u202f\u00b0C, 5% CO\u2082, 2\u202fh), and HA+HS (HA pretreatment followed by HS). In addition, cells in the Control and HS groups were treated with the selective AQP4 inhibitor TGN-020 (0.1\u202f\u03bcmol/mL, 2\u202fh before HS). The expression of HSP70, HSP90, and AQP4 was measured by western blotting; AQP4 mRNA levels were assessed by RT-PCR. Cell proliferation viability was evaluated by CCK-8 assay, and apoptosis was detected by flow cytometry. Notably, AQP4 expression (RT-PCR and Western blot) was lower in the HA+HS group than in the HS group. Flow cytometry revealed that both HA+HS and TGN-020 treatment reduced apoptosis compared with HS alone. These findings indicate that HA attenuates HS-induced injury by downregulating AQP4 expression, and that AQP4 inhibition mimics this protective effect. AQP4 represents a potential therapeutic target for heat stroke.",

While initially viewed as a uniformly beneficial antiviral and antitumor signaling axis, emerging evidence reveals that cGAS-STING functions as a context-dependent immune rheostat whose impact is dictated by signal magnitude, timing, cellular origin, subcellular localization of signaling components, and tissue context. These parameters explain why pathway activation can promote tumor rejection, vaccine efficacy, and host defense in some settings yet drive immune suppression, metastasis, neuroinflammation, or autoinflammatory disease in others. In this Review, we synthesize mechanistic and clinical insights across agonist and antagonist strategies targeting the cGAS-STING pathway in cancer, infectious disease, neurodegeneration, and interferonopathies. We highlight why first-generation STING agonists have underperformed clinically and how next-generation delivery systems and cGAS-directed approaches may overcome these limitations. We propose a disease-centric framework that integrates spatial delivery, dosing architecture, and pharmacodynamic biomarker discovery to enable rational modulation of cGAS-STING, repositioning the pathway as a tunable immunologic control node for precision therapy rather than a binary on/off switch.",

The current treatment paradigm focuses on mitigating clinical relapses and disability accumulation, leaving the underlying serological activity unaddressed. This study evaluated the capacity of satralizumab to achieve a comprehensive remission, as defined by the Serological, Relapse, and Accumulated-disability Remission (SERA-3) target. In this multicenter, real-world cohort study, patients with NMOSD from three tertiary centers in China initiating satralizumab were enrolled. AQP4-IgG levels were measured at baseline, 6, and 12\u00a0months. Clinical efficacy [annualized relapse rate (ARR), Expanded Disability Status Scale (EDSS)] and safety were evaluated. Heterogeneity in antibody response was analyzed, and baseline characteristics potentially associated with titer reduction were explored. Of the 19 patients who were AQP4-IgG seropositive at baseline, 7 (36.84%) met the strict definition of SERA-3 Complete. Of these, 4 patients achieved seroconversion at month 6 and remained seronegative through month 12, whereas 3 first achieved seroconversion at month 12. An additional 5 (26.32%) showed a reduction in AQP4-IgG titers. Satralizumab treatment was associated with marked clinical benefit. Among 33 patients included in the clinical efficacy analysis, 27 (81.82%) remained relapse-free during follow-up, median ARR decreased from 0.92 (IQR 0.56-1.59) to 0 (IQR 0-0), and EDSS scores remained stable in most patients. Exploratory analyses suggested that patients achieving serological response were older at disease onset (57.42\u2009\u00b1\u200917.82 versus 42\u2009\u00b1\u200914.24\u00a0years, p\u2009=\u20090.039) and had experienced fewer pre-treatment relapses (median 2 versus 5, p\u2009=\u20090.049). Satralizumab was generally well tolerated, including in older patients. Our findings support SERA-3 as a potential treatment framework for NMOSD. Satralizumab was associated with attainment of serological, relapse, and disability remission in a substantial proportion of patients, supporting further prospective evaluation of SERA-3 as a hypothesis-generating outcome framework.",

Confirmed disability worsening (CDW) independent of attacks has been described but occurs infrequently in AQP4-IgG+ NMOSD and MOGAD. Confirmed disability improvement (CDI) has not been evaluated in large cohorts. We determined the frequency of CDI and CDW independent of attacks and identified clinical factors associated with these outcomes in AQP4-IgG+ NMOSD and MOGAD. This retrospective, multicenter cohort study analyzed data from the German Neuromyelitis Optica Study Group (NEMOS) registry. Adult patients with AQP4-IgG+ NMOSD or MOGAD and longitudinal Expanded Disability Status Scale (EDSS) assessments were included. EDSS episodes were defined as periods with \u22653 EDSS assessments without attacks, obtained \u226590 days after attack. CDW and CDI were defined as sustained EDSS increase or decrease (\u22651.5 for baseline EDSS 0; \u22651.0 for EDSS 1.0-5.5; \u22650.5 for EDSS \u22656.0) confirmed after at least 6 months. The primary outcomes were annualized CDI and CDW rates. Risk factors were assessed using multivariable Anderson-Gill regression models. A total of 338 EDSS episodes of 307 patients (n: 202/105, median age at EDSS change: 56/41 years, 88/49% female, both p < 0.001; AQP4-IgG+ NMOSD/MOGAD) were included. Adjusted annualized CDI and CDW rates did not differ between AQP4-IgG+ NMOSD (CDI: 0.083, 95% CI 0.029-0.233; CDW: 0.025, 95% CI 0.007-0.092) and MOGAD (CDI: 0.057, 95% CI 0.012-0.277; CDW: 0.036, 95% CI 0.002-0.513). In AQP4-IgG+ NMOSD, a lower number of prior attacks was associated with higher CDI rates (hazard ratio [HR] 0.89, 95% CI 0.82-0.97). Younger age was associated with increased CDI rates in both AQP4-IgG+ NMOSD and MOGAD (HR 0.96, 95% CI 0.94-0.99, for both). CDI and CDW independent of attacks, although rare, occur in AQP4-IgG+ NMOSD and MOGAD. The association between fewer prior attacks and higher CDI rates in AQP4-IgG+ NMOSD underscores the importance of early attack prevention. Limitations include the retrospective design, and the limited number of CDI and CDW events.",

Microglia sit at the centre of this therapeutic gap. Single-nucleus and spatial profiling has resolved several AD-associated microglial states, yet state labels remain descriptive and do not explain why adaptive engagement becomes maladaptive. We frame AD-relevant microglial dysfunction as checkpoint collapse: progressive failure of regulatory nodes that coordinate lipid sensing, lysosomal competence, neuronal restraint, and inflammatory threshold control. The central nodes are TREM2-mediated lipid and apolipoprotein sensing, progranulin-associated lysosomal regulation, CX3CR1-dependent neuron-microglia restraint, and CD33/Siglec-3 inhibitory tone. When these controls destabilise, downstream pathology can be organised around three coupled effector axes: a lipid axis centred on APOE-biased cholesterol trafficking, ACSL1/DGAT2-driven lipid-droplet accumulation, and impaired lysosomal flux; an iron/ferroptosis axis involving labile iron, phospholipid peroxidation, and insufficient GPX4/FSP1 defences; and an inflammation/complement axis linking NLRP3 activation, type-I interferon signalling, and C1q/C3-dependent synaptic engulfment to tau pathology and synapse loss. White-matter injury, astrocyte-microglia crosstalk, and cGAS-STING-linked senescence are integrated as cross-axis amplifiers. This framework is proposed as a hypothesis-generating scaffold for biomarker-informed translational studies, rather than as a validated clinical stratification system. It may help organise stage-aware therapeutic hypotheses, including regulatory-node preservation in early disease, lipid-handling restoration and ferroptosis control at intermediate stages, and complement- or senescence-directed modulation in later disease. Current glial, iron, inflammatory, and imaging biomarkers remain insufficiently specific to assign individual patients reliably to discrete pathological axes in clinical practice.",

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.",

While antibody-mediated injury to astrocytes is well documented, the intrinsic cellular responses that influence astrocyte survival under such stress remain poorly understood. In this study, differentiated U87MG astrocytoma cells served as an in vitro model to examine the effects of AQP4-IgG\u2009+\u2009ve NMOSD patient sera on microRNA-mediated signaling. Small RNA sequencing and qRT-PCR revealed that hsa-miR-6836-5p was the most strongly induced miRNA within 4\u00a0h of exposure, consistent with the peak downregulation of AQP4. Functional enrichment and target prediction identified the Hippo-YAP signaling pathway, with Discs Large Homolog 2 (DLG2) as a key downstream target. AQP4-IgG\u2009+\u2009ve sera reduced DLG2 expression, decreased LATS1 and YAP phosphorylation, and upregulated YAP-dependent pro-survival genes (CTGF, CYR61, GLI2), along with an increased BCL-2/BAX ratio, initiating an acute pro-survival response. Inhibition of miR-6836-5p restored DLG2 levels, reactivated the Hippo signaling pathway, and reinstated apoptotic signaling. These findings unveil a novel miR-6836-5p-DLG2-Hippo-YAP axis that promotes pro-survival signaling in astrocytes under autoimmune stress, indicating miR-6836-5p as a potential molecular regulator of astrocyte fate in NMOSD.",
        "42401926": "ID: 42401926\nTitle: Targeting the cGAS-STING pathway alleviates neuroinflammation and cognitive impairment induced by chronic infection of Toxoplasma gondii.\nAbstract: Chronic infection of Toxoplasma gondii has been established as a contributor to cognitive impairment via inducing sustained neuroinflammation and synaptic damage. However, the underlying mechanisms remain poorly understood. As a key regulator of both neuroinflammation and cellular senescence, Cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway is implicated in pathogenesis induced by T. gondii infection. Here, we found that cGAS-STING pathway was activated in the cerebral cortex of mouse chronically infected with T. gondii, as indicated by the elevated protein levels of cGAS and STING, and increased phosphorylation of TBK1 and IRF3. Pharmacological inhibition of this pathway with RU.521 and H151, specific inhibitors of cGAS and STING, significantly alleviated T. gondii-induced cognitive impairment and neuronal damage. Moreover, chronic T. gondii infection was shown to trigger senescence characterized by increased expression of senescence markers P16, P21 and P53, and senescence-associated secretory phenotypes (SASPs), including Il-1\u03b2, Il-6, Tnf-\u03b1, Cxcl1, Cxcl10 and Mmp9. In addition, elevated expression of \u03b2-galactosidase, a senescence marker, was predominantly observed in neurons compared to microglia and astrocytes, indicating a primary role for neurons in infection-associated senescence. Notably, these phenotypes of senescence were rescued by inhibition of the cGAS-STING pathway. Collectively, our findings demonstrate that chronic infection of T. gondii activates the cGAS-STING pathway, which in turn drives neuroinflammation and cognitive dysfunction in which neuronal senescence plays a contributory role. Targeting this pathway alleviates T. gondii-induced cognitive decline, highlighting its therapeutic potential against infection-triggered neurodegenerative diseases.",

Impaired glymphatic function leads to the deposition of metabolic waste products in the brain potentially causing inflammation leading to various symptoms in ME/CFS. While the glymphatic function has been assessed in other neurodegenerative diseases using 'diffusion tensor imaging along the perivascular space' (DTI-ALPS), it has not been studied in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). This preliminary study investigates glymphatic function in 58 participants (ME/CFS\u202f=\u202f31 and healthy controls\u202f=\u202f27) using the DTI-ALPS index derived from DTI data acquired with 3\u202fT MRI. The bilateral hemispheric DTI-ALPS index was estimated to assess glymphatic function, and an asymmetry index was calculated to determine interhemispheric asymmetry in glymphatic function. We found that the global DTI-ALPS index was significantly lower in ME/CFS patients compared to healthy controls (ME/CFS: 1.44\u202f\u00b1\u202f0.086; healthy controls: 1.51\u202f\u00b1\u202f0.11, p\u202f=\u202f0.014), indicating reduced glymphatic function in ME/CFS.

The vast majority of patients are diagnosed at the symptomatic stage, when substantial neuronal loss has already occurred and the therapeutic window for disease-modifying treatment has closed. Recently approved disease-modifying therapies have created an urgent clinical need for pre-symptomatic patient identification. The cardiovascular risk factors most commonly managed in primary care -- hypertension, dyslipidemia, type 2 diabetes, atrial fibrillation, and chronic heart failure -- are among the most powerful modifiable antecedents of AD pathology, operating through systemic inflammation, cerebral small vessel disease, impaired glymphatic clearance, and tau hyperphosphorylation. The biomarkers used to monitor these conditions -- C-reactive protein, cardiac troponin, NT-proBNP, and homocysteine -- reflect active neurodegeneration risk processes already measured routinely in primary care. This clinical perspective proposes a three-stage\u00a0integrated neuro-cardiological screening protocol linking cardiovascular biomarker assessment to plasma P-tau217 blood testing for AD confirmation. This framework addresses the implementation gap identified in recent United States primary care literature and represents a practical step toward closing the AD diagnostic gap.",

Neuroinflammatory processes mediated by glial cells play crucial roles in the pathophysiology of these and other diseases, defined as TDP-43 proteinopathies. Here, we characterized region-specific glial activation in two conditional mouse models: hTDP-43-WT (overexpressing nuclear wild-type human TDP-43) and hTDP-43-\u0394NLS (expressing cytoplasmic TDP-43 with altered nuclear localization signal) following 1 month of transgene expression. Immunofluorescence analysis revealed distinct patterns of microglial activation across brain regions. hTDP-43-WT mice exhibited significant microgliosis in motor (MC) and somatosensory (SSC) cortices and hippocampal dentate gyrus (DG) with pronounced morphological alterations (i.e. increased soma size). Sholl analysis demonstrated reduced branching length and complexity in MC, SSC, and hippocampal subfields. hTDP-43-\u0394NLS mice displayed more pronounced microglial activation in hippocampal regions (CA1, DG) compared to cortical areas, with significant increases in microglial density. Additionally, we observed region-specific cortical astrocytosis in both models, suggesting coordinated glial reactivity. hTDP-43-\u0394NLS mice showed decreased polarization of astrocytic water channel Aquaporin-4 (AQP4) around vascular structures in SSC and hippocampal CA1/DG. The changes in AQP4 localization, which is critical for glymphatic function, support the hypothesis that this waste clearance system for the brain is altered in TDP-43 proteinopathies. These findings demonstrate that these different animal models of ALS/FTD induce distinct neuroinflammatory signatures, potentially contributing to the region-specific vulnerability observed in these diseases. Our data provide insights into early glial-mediated pathogenic mechanisms that could guide targeted therapeutic strategies for TDP-43 proteinopathies.",

Demographic and clinical data from 205 patients with aquaporin-4 immunoglobulin G (AQP4-IgG)-positive NMOSD were collected. Variables included sex, age, clinical symptoms/signs, connective tissue antibody status, inflammatory markers, cerebrospinal fluid (CSF) cell counts/oligoclonal band status, spinal cord lesion location/length, Expanded Disability Status Scale scores at onset and first relapse (18-month follow-up), and time to first relapse. Among the 205 patients, 108 (52.7%) were positive for anti-connective tissue antibodies (CTD abs+). Compared with anti-connective tissue antibodies (CTD abs-) patients, the CTD abs+ group had higher lymphocyte counts (1.82 \u00b1 0.14 vs. 1.73 \u00b1 0.07, p < 0.01), higher monocyte-to-lymphocyte ratios [0.27 (0.2) vs. 0.24 (0.16), p = 0.037], and higher CSF white blood cell counts [10 (22) vs. 6 (18)/106/L, p = 0.035]. They also showed a higher rate of oligoclonal band positivity (27.78% vs. 10.31%, p\u00a0=\u00a00.002), a higher proportion of patients with an increased 24-hour intrathecal synthesis rate (54.6% vs. 40.2%, p\u00a0=\u00a00.039), and higher CSF immunoglobulin levels [5.755 (6.37) vs. 4.15 (3.53) mg/dL, p < 0.001] at initial onset. No significant differences were observed between the CTD abs+ and CTD abs- groups in the distribution of lesions or the length of affected spinal cord vertebral segments at initial onset. However, patients in the CTD abs+ group had higher Expanded Disability Status Scale scores at first relapse and a higher annualized relapse rate over the 18-month follow-up period(p <\u00a00.05for both). In summary, among AQP4-IgG-positive patients with NMOSD, CTD abs+ was associated with higher lymphocyte counts, a higher MLR, higher CSF white blood cell counts, higher CSF immunoglobulin levels, a higher 24-hour intrathecal IgG synthesis rate, and higher OCB positivity. CTD abs positivity may therefore indicate a more severe inflammatory profile; however, it does not appear to predict earlier relapse, but does appear to predict a higher annualized relapse rate.",

Fatty acid binding protein 5 (FABP5), a lipid chaperone, has been implicated in chronic inflammation. However, whether FABP5 regulates pyroptosis and its pathological role in epilepsy remains uncharacterized. Here, FABP5 was upregulated in astrocytes from temporal lobe epilepsy (TLE) patients, epileptic mice, and primary cells. Deletion of astrocytic Fabp5 significantly attenuated pyroptosis, neuronal loss, and seizure activity in epilepsy. Furthermore, cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway was identified as the downstream signaling of FABP5 by RNA sequencing analysis. Mechanistically, Fabp5 knockdown reduced lipid overload, alleviated mitochondrial dysfunction, and suppressed cGAS-STING activation. Pharmacological inhibition of mitochondrial fatty acid import recapitulated these protective effects. In contrast, Sting overexpression abolished the reduced pyroptosis level by Fabp5 knockdown, whereas STING inhibition using C-176 attenuated pyroptosis and seizure activity. Collectively, these findings revealed the regulatory role of FABP5-cGAS-STING-pyroptosis axis in the progression of epilepsy and highlighted the promising potential of astrocytic FABP5 as a therapeutic target for epilepsy.",

Literature searches were conducted from January 2009 to March 2025 using PubMed and other biomedical databases. Available preclinical evidence suggests that marine-derived proteins and peptides may exert neuroprotective effects through multiple mechanisms, including activation of antioxidant defense pathways via Nrf2-mediated signaling, modulation of NF-\u03baB-associated neuroinflammatory responses, regulation of serotonergic and dopaminergic neurotransmission, and attenuation of amyloid-\u03b2 aggregation. Experimental studies conducted in animal models have reported improvements in cognitive performance, reductions in oxidative stress biomarkers, and decreased production of pro-inflammatory cytokines following administration of marine protein hydrolysates. Clinical translation of marine-derived bioactive peptides remains challenging due to the following factors: standardization of extraction, bioavailability, batch-to-batch variability, allergenic potency, and complex regulatory requirements. Ongoing new approaches using nano-formulation, synthetic biology, and Artificial Intelligence (AI) in the discovery of peptides hold the promise of enhancing their stability, targeting, and scalability. However, in order to validate the therapeutic utility of these approaches, it will require large, well-designed clinical studies.",

In parallel, the glymphatic system has emerged as a plausible integrative mechanism linking these domains, because it is a glia-dependent pathway supporting cerebrospinal fluid-interstitial fluid exchange and metabolic-waste clearance, with activity strongly modulated by deep non-rapid eye movement (NREM) sleep. This narrative review synthesizes evidence that glymphatic-related magnetic resonance imaging (MRI) proxies, particularly diffusion tensor imaging along the perivascular space (DTI-ALPS), are altered in depression, while emphasizing that DTI-ALPS is an indirect marker of perivascular diffusion rather than a direct measure of glymphatic flow. We define four key research gaps: scarcity of treatment-resistant depression (TRD)-specific cohorts, regional and technical heterogeneity across MRI studies, and uncertainty about causal direction relative to sleep disturbance and inflammation. Altered indices appear to relate to fatigue, psychomotor retardation, cognitive impairment, rumination, suicidality, systemic inflammation, oxidative stress, and HPA-axis dysregulation. We integrate opposite-direction findings, including elevated ALPS in drug-naive somatic depression, into a state- and subtype-dependent working model rather than a unidirectional dysfunction framework. Therapeutic implications are organized by target specificity, including sleep-dependent clearance, perivascular exchange, aquaporin-4 (AQP4) polarization, vascular pulsatility, and neuroimmune modulation. We propose falsifiable predictions and negative-control analyses to distinguish a glymphatic-related model from additive effects of insomnia, inflammation, and vascular risk. Overall, the current evidence supports a cautious translational framework for biomarker-informed trials in TRD-relevant phenotypes rather than a validated diagnostic biomarker.",

Diabetes was induced using a high-fat, high-sugar (HFHS) diet combined with streptozotocin (STZ). Diabetes was induced in C57BL/6J mice using an HFHS diet followed by STZ. POCD was modeled via tibial fracture surgery under general anesthesia. Cognitive function was assessed using the Open Field Test, Y-maze, and contextual fear conditioning. cGAS-STING pathway activation was evaluated by western blot for cGAS and STING expression. Microglial activation was assessed by co-localization of Iba-1 and CD68 by immunofluorescence, and the co-localization of STING with Iba-1 in the hippocampus was examined by immunofluorescence. Hippocampal neuroinflammation was quantified by enzyme-linked immunosorbent assay (ELISA) for interleukin-1beta (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1). Neuronal injury and apoptosis were evaluated by Nissl staining and western blot for cleaved caspase-3. Compared to non-diabetic controls, diabetic mice exhibited cognitive impairments, which were more pronounced in those that underwent surgery. This was accompanied by significant hippocampal neuronal loss, upregulated cleaved caspase-3 expression, and elevated IL-1\u03b2 and TNF-\u03b1 levels. Furthermore, diabetic mice that underwent surgery displayed increased expression of microglial activation markers (Iba-1 and CD68) and evidence of cGAS-STING pathway activation in the hippocampus. Immunofluorescence co-localization experiments further suggested a predominant association of this pathway with the microglial marker Iba-1. These findings suggest that surgery-associated overactivation of the microglial cGAS-STING pathway in the hippocampus may exacerbate neuroinflammation and neuronal injury, thereby contributing to cognitive decline in diabetic mice.",
        "42412752": "ID: 42412752\nTitle: Chronic intermittent hypoxia impairs glymphatic function in male mice through ENT-dependent adenosine dysregulation.\nAbstract: Chronic intermittent hypoxia (CIH), a defining feature of obstructive sleep apnea, is strongly associated with cognitive impairment and increased risk of neurodegenerative disease, yet the underlying mechanisms linking hypoxic stress to disrupted brain homeostasis remain poorly defined. Impaired glymphatic clearance has been reported in patients with obstructive sleep apnea, but whether and how intermittent hypoxia directly alters glymphatic function is unknown. Here, we investigated the effects of acute and chronic intermittent hypoxia on cerebrospinal fluid-interstitial fluid exchange in male mice and examined the molecular mechanisms governing these effects. Using tracer-based influx and efflux assays, in vivo two-photon imaging, behavioral testing, and genetic and pharmacological manipulation, we show that intermittent hypoxia exerts a duration-dependent, biphasic effect on glymphatic function. Acute exposure transiently enhanced glymphatic influx and efflux, whereas prolonged CIH progressively impaired glymphatic transport, disrupted perivascular aquaporin-4 (AQP4) polarization, reduced vascular pulsatility, and impaired spatial working memory. CIH was associated with reduced extracellular adenosine levels, suppression of cerebral energy metabolism, and altered expression of equilibrative nucleoside transporters (ENTs). Genetic ablation of AQP4 abolished CIH-induced glymphatic impairment, confirming its essential role in hypoxia-induced glymphatic dysfunction. Importantly, pharmacological inhibition or genetic deletion of ENT1 and deletion of ENT2 restored adenosine availability, normalized AQP4 polarization and vascular dynamics, and rescued glymphatic dysfunction and cognitive deficits under CIH. These findings identify ENT-dependent dysregulation of adenosine signaling as a key mechanism by which chronic intermittent hypoxia compromises glymphatic clearance, providing mechanistic insight into how sleep-disordered breathing disrupts brain waste removal and cognitive function.",
        "42413140": "ID: 42413140\nTitle: From diabetic foot to dementia: A neurovascular continuum linking systemic diabetic vasculopathy, cerebral small vessel disease, and glymphatic dysfunction.\nAbstract: Diabetes mellitus, particularly type 2 diabetes mellitus (T2DM), is increasingly recognized as a major risk factor for cognitive decline and dementia. Epidemiological studies consistently demonstrate that individuals with diabetes exhibit a significantly elevated risk of both vascular cognitive impairment and Alzheimer's disease [1,2]. Beyond hyperglycemia, systemic vascular dysfunction has emerged as a central mechanism underlying diabetes-related brain injury. Diabetes induces widespread vascular alterations, including endothelial dysfunction, arterial stiffening, oxidative stress, and chronic low-grade inflammation [3,4]. These processes affect both peripheral and cerebral circulation and may contribute to the development of cerebral small vessel disease (CSVD), a major substrate of cognitive decline [10-12]. Increased arterial stiffness may impair the Windkessel effect and facilitate the transmission of excessive pulsatile energy into fragile cerebral perforating arteries, thereby promoting microvascular injury and white matter damage [13-17]. In addition, diabetes-associated disruption of the neurovascular unit (NVU) may lead to blood-brain barrier dysfunction, neuroinflammation, and neuronal injury [20-30]. Impairment of the glymphatic system responsible for the clearance of metabolic waste products such as amyloid-\u03b2 and tau may further contribute to neurodegenerative processes [31-41]. In this review, we propose a \"systemic vascular continuum\" linking peripheral diabetic vasculopathy, cerebral small vessel disease, neurovascular unit dysfunction, and glymphatic impairment. Within this framework, diabetic foot ulcer (DFU) is presented as a clinically visible peripheral phenotype and surrogate marker of advanced systemic vascular injury rather than a direct causal factor [5-9]. This integrative model provides a conceptual framework for understanding diabetes-associated cognitive impairment and highlights vascular-targeted preventive and therapeutic strategies as promising approaches for risk stratification and intervention.",
        "42419635": "ID: 42419635\nTitle: The Glymphatic system: A key mechanism linking sleep to brain health and diseases.\nAbstract: Sleep is increasingly recognized as a fundamental regulator of brain homeostasis, yet the mechanisms linking sleep to neurological health have only recently begun to emerge. The glymphatic system, a brain-wide perivascular transport network, has provided a mechanistic framework connecting sleep physiology with brain health and disease. Accumulating evidence indicates that glymphatic activity is markedly enhanced during sleep through coordinated regulation of vasomotion, norepinephrine oscillations, aquaporin-4 polarization, extracellular space expansion, respiration, and meningeal lymphatic drainage. Conversely, chronic sleep disruption impairs glymphatic transport, promotes the accumulation of neurotoxic metabolites, and contributes to neuroinflammation, thereby accelerating the progression of diverse neurological disorders. In this review, we integrate recent advances in glymphatic biology from structural organization and transport mechanisms to sleep-dependent regulation and emerging neuroimaging approaches. We critically evaluate current evidence supporting glymphatic dysfunction in neurodegenerative diseases, traumatic brain injury, cerebrovascular disorders, psychiatric disorders, brain tumors, and ocular diseases, highlighting sleep-related impairment as a common mechanistic denominator. Particular emphasis is placed on the translational potential and limitations of non-invasive imaging biomarkers, including DTI-ALPS, dynamic contrast-enhanced MRI, diffusion MRI, PET, and emerging multimodal techniques. We also discuss major controversies surrounding glymphatic physiology, including the relative contributions of bulk flow and diffusion, species-specific differences, and the challenges of validating human imaging biomarkers. Finally, we propose a conceptual sleep-glymphatic-disease axis that integrates current mechanistic knowledge with clinical translation. Understanding how sleep regulates glymphatic function may provide new opportunities for disease prevention, biomarker development, and therapeutic intervention across a broad spectrum of brain disorders.",
        "42421041": "ID: 42421041\nTitle: Advances in electroacupuncture for perioperative neurocognitive disorders: mechanisms and clinical evidence.\nAbstract: Perioperative neurocognitive disorders (PND), including postoperative delirium, delayed neurocognitive recovery, and postoperative cognitive dysfunction, are common complications in older surgical patients and are associated with impaired recovery, reduced quality of life, and increased postoperative morbidity. Current management remains largely supportive and preventive, and effective targeted therapies are still lacking. Electroacupuncture (EA), as a minimally invasive neuromodulatory intervention, has attracted increasing attention because of its potential multi-target regulatory effects. This review summarizes current mechanistic and clinical evidence regarding EA for PND. Preclinical studies suggest that EA may modulate several interacting pathological processes, including neuroinflammation, oxidative stress, autophagy dysfunction, ferroptosis, mitochondrial injury, microbiota-gut-brain axis dysregulation, and hippocampal synaptic plasticity. Recent PND/POCD animal studies further support EA-related regulation of NLRP3 inflammasome activation, cGAS-STING signaling, SIRT1/NRF2/GPX4-mediated ferroptosis, AMPK/SIRT1/FOXO1/PINK1/Parkin-related autophagy pathways, and MAPK-related synaptic plasticity. Clinical studies and meta-analyses suggest that EA and related acupoint-based electrical stimulation techniques may reduce early postoperative cognitive decline and improve short-term cognitive outcomes in older surgical patients. However, the overall evidence remains limited by heterogeneous stimulation protocols, variable acupoint prescriptions, incomplete blinding, short follow-up, and reliance on cognitive screening scales. Several proposed mechanisms are still partly inferred from non-PND models. Future studies should use standardized EA protocols, clinically relevant PND models, dynamic mechanistic assessments, and adequately powered sham-controlled trials to clarify the therapeutic role of EA in PND.",

This review summarizes the role of nonstructural protein 1 (NS1), a multifunctional glycoprotein found in intracellular and secreted forms, as a key regulator of innate immunity. NS1 modulates several pattern recognition receptor pathways, including TLRs, RLRs, SR-B1-related mechanisms, and inflammasome platforms, thereby altering cytokine and interferon responses. Its effects are virus- and context-dependent. WNV NS1 inhibits TLR3/TRIF signaling, reducing IRF3 activation, type I interferon production, and interferon-stimulated gene expression. In contrast, DENV NS1 is linked to inflammatory signaling, particularly through TLR4. At the cytosolic level, NS1 from DENV, WNV, and ZIKV disrupts RIG-I/MDA5-MAVS signaling and weakens IFN-\u03b2 induction. NS1 also affects inflammasome pathways: DENV promotes IL-1\u03b2 release through a CD14-dependent mechanism, ZIKV suppresses cGAS-mediated antiviral signaling, and JEV promotes NLRP3 inflammasome assembly. Overall, NS1 selectively dampens interferon-mediated antiviral defenses while sustaining or enhancing inflammation, contributing to endothelial dysfunction, neuroinflammation, and severe disease.",

This review comprehensively examines the central role of PROTACs in regulating critical PCD mechanisms, including ferroptosis induction via GPX4 degradation, pyroptosis regulation through stimulator of interferon genes (STING) targeting, necroptosis modulation by MLKL/RIPK1 degradation, apoptosis activation through BCL-2/MDM2 elimination, and autophagy regulation via dual ubiquitin-proteasome and lysosomal pathways. These approaches effectively address the limitations of traditionally \"undruggable\" targets while demonstrating unique mechanistic properties and clinical promise. Currently, over 30 PROTAC candidates have entered clinical trials, including the estrogen receptor (ER) degrader ARV-471 for breast cancer and the IRAK4 degrader KT-474 for inflammatory diseases, both showing remarkable efficacy in overcoming drug resistance. While challenges remain in delivery systems, E3 ligase selectivity, and toxicity management, innovative technologies, such as nanocarriers, covalent PROTACs, and novel E3 ligases (e.g., RNF114) are advancing PROTAC applications in oncology, neurodegenerative disorders, and immune-related diseases. Future research will focus on optimizing molecular design, expanding the E3 ligase repertoire, and developing combination therapies. These efforts will establish PROTACs as groundbreaking solutions for intractable diseases, with their precise control of PCD pathways opening new therapeutic avenues. The technology's ability to selectively modulate cell death mechanisms positions it as a transformative approach in precision medicine.",

The coupling of local fluid shear stress-particularly disturbed flow (DF) and oscillatory shear stress (OSS)-with vascular wall stiffness constitutes the core mechanical driver of site-specific plaque progression. This narrative review systematically elucidates the cutting-edge molecular mechanisms of vascular wall-mediated \"mechanopriming\" and endothelial mechanotransduction. We highlight how the Piezo1 ion channel and the 5-HT1B receptor act as \"coincidence detectors,\" precisely integrating fluid shear stress and matrix stiffness signals to subsequently activate central signaling hubs such as YAP and c-REL. The dysregulation of these mechanopathways not only triggers pathological reprogramming of endothelial cells-including cGAS-STING-mediated deep senescence, NLRP3-driven pyroptosis, and endothelial-to-mesenchymal transition (EndoMT)-but also impairs RBPJ-epigenetically regulated macrophage efferocytosis and drives pathological matrix remodeling by smooth muscle cells and fibroblasts via complex transcellular communication networks. Clinically, the fusion of multimodal imaging with computational fluid dynamics (CFD), alongside emerging ultrafast ultrasound vector flow imaging, has pioneered novel avenues for the high-fidelity in vivo quantification of wall shear stress (WSS). Finally, we critically evaluate current research limitations and prospectively discuss frontier shear stress-targeted therapeutic strategies-such as \"mechanodrugs,\" biomimetic nanodelivery, and hemodynamic stent optimization-proposing a novel precision cardiovascular medicine framework that formally incorporates localized hemodynamic parameters into established clinical risk stratification algorithms like the ASCVD and SCORE2 models.",

Evidence links gut-brain axis dysfunction and metabolic disturbances to AD. Although cannabidiol (CBD) has neuroprotective effects, its use is limited by poor bioavailability and brain delivery. Arginylglycylaspartic acid (RGD)-functionalized, CBD-loaded lipid nanoparticles (CBD/LNP-RGD) were developed to enhance targeted delivery across the blood-brain barrier (BBB) via integrin \u03b1v\u03b23-mediated transcytosis. Cellular uptake and BBB permeability were evaluated in vitro. Anti-inflammatory and antioxidant effects were assessed in A\u03b2/LPS-induced models. In vivo efficacy was examined using cognitive-behavioral tests, including the novel object recognition and the Morris water maze. Metabolic parameters, histopathology, synaptic protein expression, and gut barrier integrity were also evaluated. CBD/LNP-RGD demonstrated a 3-fold increase in cellular uptake and a 65% enhancement in BBB transport compared to non-targeted formulations. Treatment significantly reduced pro-inflammatory cytokines (i.e., IL-6 and TNF-\u03b1, p\u202f<\u202f0.001) and intracellular reactive oxygen species (p\u202f<\u202f0.001). In vivo, CBD/LNP-RGD improved cognitive performance comparable to Donepezil (p\u202f<\u202f0.001). Additionally, it normalized glycemic control, insulin resistance, and triglyceride levels without hepatic or renal toxicity. At the tissue level, CBD/LNP-RGD reduced A\u03b2 and tau pathology, restored short-chain fatty acids, preserved hippocampal neuronal integrity, and upregulated synaptophysin and PSD-95 proteins. Enhanced intestinal barrier function was evidenced by increased expression of tight junction proteins ZO-1 and occludin. CBD/LNP-RGD represents a multifunctional nanotherapeutic platform that improves brain delivery and exerts neuroprotective, anti-inflammatory, antioxidant, and metabolic regulatory effects. Its ability to modulate both central pathology and the gut-brain axis highlights its potential as a disease-modifying strategy for Alzheimer's disease.",

However, the sex-associated clinical phenotypes and underlying neuroinflammatory mechanisms in amyotrophic lateral sclerosis (ALS) remain poorly understood. This study integrated multimodal clinical assessments, cerebrospinal fluid (CSF) neuroimmune biomarkers, neuroimaging-based glymphatic metrics, and complementary animal analyses to characterize shared and sex-associated alterations in male and female ALS patients. Two independent cohorts including 158 newly diagnosed ALS patients and 112 healthy controls (HCs) underwent evaluations of motor function, cognition, sleep disturbances, and emotional symptoms. Glymphatic function was assessed using choroid plexus volume (CPV), diffusion-derived analysis along the perivascular space (ALPS) index, and white-matter free-water (FW) fraction. In the original cohort, 12 CSF biomarkers spanning astrocytic activation, neuroinflammation, TDP-43 pathology, synaptic dysfunction, and axonal injury were quantified, and glial fibrillary acidic protein (GFAP), interleukin-6 (IL-6), and interleukin-18 (IL-18) were further examined in an independent verification cohort. Complementary neuroimmune alterations were further examined in TDP-43 N390D knock-in mice using ELISA and immunofluorescence. Male ALS patients showed markedly elevated CSF GFAP, IL-6, and IL-18 compared with female ALS patients and HCs after false discovery rate correction (q\u00a0<\u00a00.05). Female ALS patients exhibited increased CSF IL-6 versus HCs, whereas GFAP and IL-18 levels were unchanged. Female ALS patients also demonstrated more severe depressive symptoms and post-traumatic stress disorder than male ALS patients and HCs (p\u00a0<\u00a00.05). Both sexes displayed glymphatic impairment characterized by increased CPV and FW and reduced ALPS index, as well as pronounced sleep disturbances relative to HCs (all p\u00a0<\u00a00.05), with no clear sex-related differences. Complementary animal data showed that, at a fixed chronological age, male TDP-43 N390D mice exhibited more severe motor impairment accompanied by higher brain levels of GFAP, IL-6, and IL-18 and more prominent astrocyte-associated IL-6 and IL-18 signals than female mutant mice. Although microglial activation was also observed in TDP-43 N390D mice, no clear sex-related difference was detected at the sampled age. This multimodal clinical-translational study reveals sex-associated neuroinflammatory heterogeneity in ALS. Male patients exhibit a more pronounced GFAP-, IL-6-, and IL-18-related inflammatory profile, whereas female patients display more prominent affective disturbances. Glymphatic dysfunction and sleep impairment emerge as common pathological pathways across sexes. These findings highlight sex as a crucial biological variable shaping ALS heterogeneity and underscore the importance of incorporating sex-stratified analyses in future ALS neuroimmune research and clinical trials.",

Here we tested whether hyperbaric oxygen (HBO) improves CFS-related cognitive impairment in mice and examined a glycerophospholipid-metabolic mechanism. CFS was induced by a 3-week multi-stressor paradigm, and mice received HBO (100% O2, 2.5 ATA, 60\u202fmin/session, 4 sessions/week for 3 weeks). HBO improved fatigue-/depressive-like behaviors and rescued spatial and recognition memory. Histology and ultrastructure analyses showed that HBO reduced hippocampal neuronal injury and preserved blood-brain barrier (BBB) integrity, accompanied by decreased pro-inflammatory cytokines and attenuated microglial activation. Untargeted LC-MS metabolomics revealed that HBO partially reversed CFS-associated metabolic shifts and enriched glycerophospholipid metabolism. Hippocampal Western blot further showed that HBO reduced CFS-associated elevation of PLA2G4A signaling. In parallel, PGE2 levels were decreased by HBO and by AACOCF3, supporting a PLA2G4A-related downstream inflammatory lipid mediator axis. In BV2 microglia and in vivo CFS mice, pharmacological PLA2G4A inhibition with AACOCF3 attenuated inflammatory and behavioral abnormalities, and subsequent HBO did not confer additional significant benefit. Together, these data support that HBO alleviates CFS-related cognitive impairment in this model, at least in part, through suppression of neuroinflammation involving a PLA2G4A-linked glycerophospholipid metabolic pathway.",

Despite the recognized role of specialized cerebellar glia in cerebellar development and dysfunction, immune activation and non-immune glial responses remain understudied in SCAs. This narrative review compiles evidence from cellular, animal, and human models on the cerebellar immune landscape and the specific pathways that drive homeostatic failure and neuroinflammatory cascades across SCA subtypes. Microgliosis emerges consistently-and often early- as a generalized feature across the SCA spectrum, preceding neurodegeneration in several subtypes. Concurrently, reactive astrogliosis extends broadly, reflecting widespread macroglial surveillance and metabolic stress regulation throughout histologically preserved gray matter, with specialized homeostatic failure of Bergmann glia in SCA1, SCA2, and SCA7. Peripheral inflammation, manifests as early as the prodromal stage and correlates with the cognitive-affective deficits in SCA2 and associates with the mutation size in SCA3, positioning it as integral to pathogenesis rather than epiphenomenal. Diverse, partially shared signaling pathways converge on multi-lineage glial breakdown and reciprocal neuroimmune crosstalk. These mechanisms involve NF-\u03baB (SCA1,3,17), cGAS-STING (SCA2), TLR/MyD88 (SCA6), and JNK/c-Jun (SCA1,2,7). This review establishes abnormal reciprocal immune/non-immune glia crosstalk as a core pathogenic principle across SCAs, revealing novel therapeutic opportunities. In fact, targeting convergent signaling nodes such as NF-\u03baB, or JNK pathways, holds disease-modifying potential across multiple subtypes. Future research should prioritize standardized comparative studies, longitudinal analyses linking both inflammation and non-immune glial pathology to clinical progression, and clinical trials evaluating targeted immunomodulatory and glial homeostatic-supportive agents.",

In NSCLC, immunometabolism not only sustains tumor growth but also enables immune evasion through altering the immune cell behavior within the tumor microenvironment. Despite multiple signaling pathways having been implicated in the process, the integration of inflammatory cytokines and metabolic signaling underlying autophagy dysregulation in NSCLC remains unexplored. From a cellular perspective, the review summarizes the immunometabolic and regulatory functions of IL-6 and IL-17 in inflammaphagy and their integration into immunometabolic networks. The conserved contributions of key regulatory pathways, including BMP, DUSP, FOXO, SPROUTY, and STING, in shaping immune cell metabolism and tumor progression were also underscored. A narrative review of recent literature was performed focusing on integrating findings from experimental and clinical studies to construct a unified framework defining cytokine interactions, immune metabolism, and tumor progression. IL-6 and IL-17 are critical regulators for metabolically adapting tumor cells while influencing macrophages, T-cells, neutrophils, and other immune subsets towards attaining a metabolic shift. Additionally, conserved trajectories of BMP, DUSP, FOXO, SPROUTY, and STING modulate metabolic homeostasis for tumor development, highlighting their crosstalk between inflammatory and metabolic networks. Advances in understanding the interconnected role of inflammatory cytokines, autophagy, and metabolism may identify novel therapeutic targets and improve the effectiveness of immunotherapy towards achieving the goal of precision oncology.",

Using aged mice, we examined the impact of abdominal surgery on cognition, glymphatic activity, and astrocyte function. Sex-dependent mechanisms were investigated by integrating single-cell RNA sequencing with astrocyte-specific genetic and pharmacological manipulation. Abdominal surgery induced male-specific deficits in recognition and spatial memory, reduced hippocampal glymphatic influx, and glutamate accumulation in aged mice. These changes were associated with male-specific upregulation of glutamate signaling in a distinct astrocyte subpopulation, enhanced astrocytic glutamate carboxypeptidase II (GCPII) activity, and loss of aquaporin-4 (AQP4) polarization. Astrocyte-specific GCPII knockdown rescued cognitive deficits and hippocampal glymphatic influx, consistent with pharmacological GCPII inhibition ameliorating glutamate levels, AQP4 polarization, and cognitive performance. These findings identify astrocytic GCPII-mediated glutamate dysregulation as a mechanism contributing to sex-specific postoperative cognitive vulnerability in aging.",

Using diffusion MRI data from 850 healthy young adults and 150 healthy ageing participants from the Human Connectome Project, I systematically evaluated the influence of region-of-interest (ROI) placement and ventricular anatomy on ALPS measurements. Reference ALPS implementations demonstrated substantial hemispheric variability, with a median left-right difference of 12.5% and marked asymmetry in the underlying numerator and denominator tensor components. A two-stage optimisation framework incorporating fibre-pool alignment, hemispheric symmetry, component stability, and directional purity identified anatomically improved ROI configurations that significantly increased fibre specificity and reduced measurement variability in independent validation cohorts. Despite these improvements, residual hemispheric asymmetry persisted, suggesting an intrinsic anatomical contribution to ALPS variability. In the healthy ageing cohort, ventricular volume emerged as the strongest predictor of ALPS, explaining substantially more variance than chronological age. Voxel-wise deformation-based morphometry demonstrated that lower ALPS values were associated with ventricular and periventricular expansion, while optimisation increased coupling between ALPS and ventricular anatomy. Collectively, these findings indicate that ALPS measurements are strongly influenced by ROI definition, ventricular morphology, and surrounding periventricular tissue architecture. Rather than functioning as a direct measure of glymphatic transport in isolation, ALPS appears to represent a composite anatomical diffusion biomarker shaped by both methodological implementation and underlying neuroanatomy. These results provide a framework for improving methodological standardisation and interpretation of ALPS measurements in future neuroimaging studies.",

There is mounting evidence suggesting that glymphatic dysfunction is an important cause of neurodegenerative diseases, characterized by failure of cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange due to abnormal clearance. Mechanistically, this dysfunction is affected by aging, astroglial aquaporin-4 (AQP4) depolarization, vascular impairment, sleep abnormalities, oxidative damage, and neuroinflammation. Additionally, aberrant glymphatic flow acts as a crucial link between peripheral and central pathologies, amplifying neurodegeneration via altered solute transport and inflammation signaling. Glymphatic dysfunction has been found to be involved in diseases such as AD, PD and HD, thus indicating the widespread significance of glymphatic pathology. Therapeutically, targeting glymphatic function through modulation of AQP4 polarization, improving sleep-dependent clearance, and decreasing oxidative and inflammatory mechanisms may provide promising strategy for disease modification. This review provides a comparative and mechanistic overview of glymphatic dysfunction across AD, PD, and HD, highlighting peripheral-central interactions, biomarkers, imaging approaches, and therapeutic strategies, while addressing unresolved issues related to transport mechanisms, causality versus epiphenomenon, and translational limitations.",
        "42433366": "ID: 42433366\nTitle: Beyond AQP-4: convergent glymphatic-meningeal lymphatic dysfunction underlying multifactorial migraine pathogenesis.\nAbstract: The glymphatic system (GS) functions as a critical pathway for waste clearance from the brain, facilitating soluble protein and metabolite drainage. Recently, GS dysfunction has emerged as a potential contributor to migraine pathophysiology. GS operates similarly to the peripheral lymphatic system, dependent on astrocytes for metabolic waste removal. The clearance process involves cerebrospinal fluid entering the peri-arterial spaces, moving into the interstitial fluid via aquaporin-4 (AQP-4) channels at astrocyte feet, and eventually being drained into the cervical lymph nodes. As a downstream effector of the glymphatic system (GS), meningeal lymphatic vessels (MLVs) play a critical role in immune surveillance and regulation of cerebrospinal fluid (CSF) efflux. Calcitonin gene-related peptide (CGRP) is primarily involved in pain transmission and neuroinflammation within the nervous system. Within MLVs, CGRP modulates CSF outflow by promoting VE-cadherin rearrangement, thereby influencing pain responses in migraine mice. GS dysfunction has been observed in mice with migraine and may associate with cortical spreading depression (CSD)-induced transient perivascular space (PVS) closure. GS dysfunction has also been observed in the nitroglycerin (NTG)-induced mice migraine model. Consequently, this dysfunction might lead to the accumulation of CGRP, reactive oxygen species, and inflammatory factors, contributing to migraine initiation. In addition, CSD, a key mechanism in migraine aura, is postulated to induce transient PVS closure, disrupting GS flow. Further, impaired GS clearance would potentiate glutamatergic signaling and trigger neuroinflammation. Furthermore, AQP-4, a key component of GS, plays a crucial role in maintaining PVS function and modulating neuroinflammation. Reduced expression and impaired polarization of AQP4 may further impair GS clearance, leading to the accumulation of pathogenic mediators. GS dysfunction might be exacerbated by CSD and neuroinflammation. Further research is warranted to elucidate the underlying mechanisms and explore potential therapeutic targets aimed at restoring GS function in patients with migraine.",

In this Account, we summarize our systematic efforts to address these challenges through two complementary strategies: 1) functionalization of Pt(IV) prodrugs and 2) spatially controlled targeted delivery. The kinetic inertness and octahedral geometry of Pt(IV) complexes offer a versatile platform for axial functionalization, allowing the integration of diverse bioactive ligands that are released upon intracellular reduction. Exploiting this feature, we have developed multifunctional Pt(IV) prodrugs that co-target DNA damage repair and apoptotic pathways, rewire cholesterol and energy metabolism, induce nonapoptotic cell death including PANoptosis and autophagy-associated death, and epigenetically silence resistance-associated gene networks via chromatin compaction. To engage the tumor immune microenvironment, we have incorporated immunomodulators\u2500including STING agonists, TREM2/CD33 inhibitors, and STAT3 blockers\u2500to amplify innate and adaptive antitumor immunity. Furthermore, we have developed radiotherapy-responsive Pt(IV) prodrugs that undergo rapid, X-ray-triggered reduction mediated by hydrated electrons, enabling spatiotemporally precise drug activation with markedly attenuated systemic toxicity. This strategy is currently advancing toward clinical translation through IND-enabling studies. In parallel, we have established targeted delivery platforms to improve the spatial precision of Pt agents. Mitochondria-targeted complexes redirect cytotoxicity to an organelle lacking efficient DNA repair, disrupting bioenergetics and triggering intrinsic apoptosis. At the tissue level, biotin-mediated targeting exploits overexpressed vitamin transporters for tumor-selective accumulation, while Pt(IV)-antibody conjugates (Pt-ADCs) achieve antigen-specific delivery, upregulate tumor MHC-I expression, expand TCR clonotypes, and synergize with PD-1 blockade. Additionally, a stimuli-responsive in situ self-assembly strategy enables enzyme-triggered nanostructure formation and intracellular disassembly for enhanced tumor accumulation and burst drug release. An immunocompetent patient-derived organoid platform has been established to screen these agents in a clinically relevant setting. The integration of multifunctional modulation, targeted delivery, and externally controlled activation within single Pt-based systems creates a synergistic framework that simultaneously addresses resistance and toxicity. Moving forward, our research will focus on optimizing pharmaceutical properties, advancing radiotherapy-responsive Pt(IV) prodrugs and Pt-ADCs toward clinical evaluation, and refining predictive screening platforms. These programmable Pt therapeutics hold considerable promise for delivering safer and more effective precision chemotherapy to cancer patients.",

Here, we identify aberrant STING activation as a key driver of microglial pyroptosis and post-SAH injury. Transcriptomic and biochemical analyses support a close association between STING signaling and microglial pyroptosis, with MAPK signaling acting as a functionally relevant downstream pathway. Based on this mechanistic insight, we engineered MG1 peptide-functionalized, neutrophil membrane-coated STING-PROTAC nanoparticles (MG1@NM-Px) to enable blood-brain barrier penetration, microglia-targeted delivery, and efficient STING degradation in vivo. This catalytic degradation suppressed the inflammasome-related activation and GSDME-associated pyroptotic signaling, reduced pro-inflammatory cytokine secretion, and prevented neuronal apoptosis. Histopathological examination showed preserved Nissl body integrity, while behavioral testing revealed significant improvements in neurological function. Collectively, this engineered neutrophil membrane-coated STING-PROTAC nanoplatform effectively degrades STING, inhibits microglial pyroptosis, and provides robust neuroprotection in SAH. This work establishes a novel biomimetic nanomedicine strategy for SAH therapy and opens new avenues for treating neuroinflammation-related disorders.",

Although cigarette smoke-induced oxidative stress has long been recognized as the predominant pathogenic driver, conventional inflammatory theories fail to fully account for the sustained inflammatory state that persists even after smoking cessation. Accumulating evidence indicates that COPD is governed by a metabolite-centered epigenetic regulatory network. Intracellular metabolic intermediates function not only as substrates for energy metabolism, but also as signaling molecules that directly modulate chromatin architecture and transcriptional programs. In this context, metabolic reprogramming emerges as a pivotal determinant of immune cell fate and inflammatory memory formation. This review systematically summarizes recent research advances in the \"metabolite-redox-epigenetics\" axis in COPD. We specifically discuss histone lactylation as a glycolysis-dependent inflammatory amplification mechanism and propose that histone succinylation represents a redox-sensitive epigenetic mechanism linked to mitochondrial dysfunction, bridging tricarboxylic acid (TCA) cycle dysregulation and persistent immune activation. We further integrate acetylation, crotonylation, \u03b2-hydroxybutyrylation, DNA methylation, and RNA m6A modification to construct a unified immunometabolic regulatory network. We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility, which stably enforces pathogenic immune phenotypes. Targeting metabolite-driven epigenetic remodeling may offer novel therapeutic strategies to reverse chronic inflammatory memory and restore immune homeostasis. Recent evidence further suggests that cGAS-STING-mediated mitochondrial DNA sensing, inflammasome-dependent pyroptosis, gut-lung axis-derived metabolites, and AMPK/SIRT1/PGC-1\u03b1 signaling may provide additional links between metabolic stress, epithelial injury, and immune dysfunction.",

This study aimed to elucidate the mechanistic role of the cyclic GMP-AMP synthase/stimulator of interferon genes (cGAS/STING) signaling pathway in disrupting gut-liver axis homeostasis following cerebral ischemia. Using a middle cerebral artery occlusion (MCAO) rat model, we employed a multidisciplinary approach combining behavioral, histological, molecular, and biochemical assays. We demonstrated that MCAO-induced cerebral infarction led to significant neurological deficits and behavioral impairment. Concurrently, Western blot analysis confirmed a significant upregulation of caspase-3, STING, cGAS, and phosphorylated IRF3 in the hippocampus. Consistent with these central changes, protein levels of caspase-3, STING, cGAS, and IRF3 were also elevated in both colonic and hepatic tissues, while the expression of tight junction proteins ZO-1 and Occludin was downregulated in the colon. H&E staining and electron microscopy of MCAO colon revealed mucosal disruption, crypt atrophy, and inflammatory infiltration, accompanied by reduced and deformed microvilli with impaired tight junctions. These changes coincided with elevated IL-12 and IL-18 levels in both the colon and liver. Immunofluorescence confirmed cGAS upregulation in MCAO colon. RT-qPCR analysis demonstrated a consistent pro-inflammatory response, with significant upregulation of cGAS, STING, IL-12, and IL-18 mRNA in the colon; elevated IL-12, IL-18, IFN-\u03b3, and IL-1\u03b2 mRNA in the liver; and increased IFN-\u03b3, IL-1\u03b2, IL-18, and IL-12 mRNA in the hippocampus. Our findings suggest cerebral ischemia-induced systemic inflammation and gut-liver axis dysfunction may be associated with the activation of the cGAS/STING pathway.",

Recent evidence suggests that STING activation can induce neuronal ferroptosis through autophagic degradation of GPX4. Taurochenodeoxycholic acid (TCDCA), a naturally occurring bile acid, has demonstrated neuroprotective properties through activation of Takeda G protein-coupled receptor 5 (TGR5). However, whether TCDCA can improve PD by modulating the cGAS-STING-ferroptosis axis remains unexplored. We investigated the effects of TCDCA treatment on motor function, dopaminergic neuronal survival, oxidative stress markers, ferroptosis-related proteins (GPX4, SLC7A11, ACSL4), and cGAS-STING signaling components in the substantia nigra of male mice subjected to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) administration and in MPP\u207a-treated SH-SY5Y cells. Behavioral assessments demonstrated that TCDCA significantly improved motor dysfunction in both open field and pole tests. TCDCA treatment markedly increased tyrosine hydroxylase-positive neurons and reduced oxidative stress markers including malondialdehyde and ferrous iron levels while restoring superoxide dismutase activity and glutathione content in the substantia nigra. Results showed that TCDCA upregulated TGR5 expression and concurrently suppressed cGAS and STING activation in both in vivo and in vitro PD models. Importantly, TCDCA treatment significantly enhanced the expression of anti-ferroptotic proteins GPX4 and SLC7A11 while reducing pro-ferroptotic ACSL4. These neuroprotective effects were associated with TGR5 upregulation and cGAS-STING pathway suppression. Our findings demonstrate that TCDCA alleviates PD-related neurodegeneration by inhibiting cGAS-STING-mediated ferroptosis through TGR5 activation, suggesting that TCDCA holds promise as a candidate drug for the treatment of PD.",

T cell-specific TFAM-deficient mice are immunocompromised, often succumbing to viral infection, and their T cells are unresponsive to T-cell antigen receptor (TCR) stimulation, suggesting that TFAM-mediated mitochondrial activity regulates T-cell activity, such as effector function and memory formation. In contrast to the attenuation of immune response, TFAM deficiency may also induce inflammatory responses, raising the possibility that TFAM deficiency results in inflammation-mediated autoimmune responses. Thus, besides regulating T-cell function, TFAM plays important roles in autoimmune responses. However, its role in autoimmune diseases remains uncertain. We aimed to investigate the role of TFAM in autoimmune diseases using T cell-specific TFAM-deficient mice. We detected anti-double-strand (ds) DNA antibody, and interferon alpha (IFN\u03b1) and IFN\u03b3 in the serum of TFAMfl/fl CD4Cre mice after 30 weeks of age. Mononuclear cell infiltration was observed in the kidneys. TFAM-deficient T cells exhibited leakage of mitochondrial DNA into the cytoplasm. Cytoplasmic mitochondrial DNA was associated with activation of TANK-binding kinase 1 (TBK1) and IFN regulatory factor 3 (IRF3)-the downstream molecules of the nucleic acid sensor cyclic guanosine monophosphate-adenosine monophosphate synthase/stimulator of IFN genes (cGAS/STING) machinery. mRNA expression of type I IFN genes was elevated in T cells from TFAMfl/fl CD4Cre mice. The suppressive function of Foxp3+ regulatory T (Treg) cells, which play a major role in establishment of peripheral tolerance, was reduced in the absence of TFAM. Our findings suggest that T cells in TFAM-deficient conditions may contribute to immune instability and autoimmune responses by inducing type I IFN-mediated inflammatory responses.",

A total of 450 grass carp (402.16 \u00b1 1.01 g) were randomly distributed into 18 tanks and fed one of six experimental diets with varying VB2 concentrations (0.47, 1.96, 3.45, 4.97, 6.47, and 7.98 mg/kg) for 60 d, followed by a 96 h hypoxia stress experiment. The experimental results showed that, compared with VB2 deficiency (0.47 mg/kg VB2) group, the 1.96 to 7.98 mg/kg VB2 groups enhanced the percent weight gain, specific growth rate, and feed efficiency, and exerted a growth-promoting effect on grass carp (P < 0.001). In the hypoxia group, the supplementation of VB2 (3.45-6.47 mg/kg) increased hepatic VB2 content, D-amino acid oxidase, and glutathione reductase activities (P < 0.001), thereby enhancing the function of the flavoprotein. Furthermore, the 3.45 to 6.47 mg/kg VB2 groups reduced the activities of serum aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and alkaline phosphatase (P < 0.05), thereby mitigating hepatic damage induced by hypoxia. The 3.45 to 4.97 mg/kg VB2 groups increased hepatic ATP content (P < 0.001), while reducing cytoplasmic mitochondrial DNA copy number under hypoxia stress. Compared with the VB2 deficiency group, the 4.97 mg/kg VB2 group promoted the fluorescence intensity of VDAC1, TOMM20, and OPA1 under hypoxia stress (P < 0.001), thereby improving mitochondrial structure and function. Riboflavin also mitigated hypoxia-induced hepatic inflammation. Dietary 3.45 to 7.98 mg/kg VB2 reduced the expression of pro-inflammatory factors such as il-1\u03b2, tnf-\u03b1 and ifn-1, while 3.45 to 6.47 mg/kg VB2 groups increased the expression of anti-inflammatory cytokine such as il-4, il-10, and tgf-\u03b2 (P < 0.05). Dietary 4.97 mg/kg VB2 reduced the expression of p-STING, p-TBK1, p-IRF3, and p-P65 (P < 0.05). Finally, using percent weight gain, D-amino acid oxidase (D-AAO), and alanine aminotransferase (ALT) for secondary regression analysis, VB2 requirements for sub-adult grass carp were determined to be 5.39, 5.11, and 5.49 mg/kg, respectively. Overall, this study provides a theoretical basis for the role of VB2 in alleviating hypoxia-induced hepatic inflammation and for formulating diets for sub-adult grass carp.",

It is currently known that the gut microbiota plays an important role in modulating neuroimmune signaling, which in turn may trigger anxiety-like behaviors and depressive phenotypes through the microbiota-gut-brain axis. This review aims to integrate the most recent mechanistic knowledge on treatment strategies targeting the gut microbiota to modulate neuroinflammation. This review article discusses preclinical and clinical studies that investigated microbial composition, metabolite profiles, and host-microbe interactions involved in neuroinflammatory processes. However, special attention was given to signaling via the vagus nerves and bile acids, as well as to tryptophankynurenine metabolism and short-chain fatty acids (SCFAs). To examine the potential connection between the two, researchers used animal models such as germ-free animals and antibiotic-injected mice for fecal microbiota transplantation (FMT). This article defines dysbiosis as amplifying neuroinflammatory responses by altering microglial phenotypes, disrupting the blood-brain barrier, and triggering the production of pro-inflammatory cytokines. In contrast, microbiome diversity rehabilitation through the use of probiotics, prebiotics, synbiotics, and dietary modifications reduces neuroinflammatory markers and enhances cognitive and behavioral status. Clinical trials have shown considerable promise in diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), autism spectrum disorder (ASD), and depression. However, variability in treatment protocols, treatment resistance, and host-specific factors continue to pose significant challenges. This narrative review integrates mechanistic insights into microglial activation, cytokine signaling, blood-brain barrier regulation, vagal pathways, tryptophan metabolism, and short-chain fatty acids with emerging clinical evidence and therapeutic strategies, including probiotics, prebiotics, dietary modulation, and personalized microbiome-based interventions. Despite promising therapeutic potential, microbiome engineering faces important challenges, including safety concerns, lack of standardized intervention protocols, and substantial inter-individual variability in host-microbiome responses, which currently limit clinical translation. This review focuses on both neurodegenerative and neuropsychiatric disorders, examining shared neuroinflammatory mechanisms mediated by the gut-brain axis and evaluating microbiotatargeted therapeutic strategies across these disease categories. The review discusses both preventive strategies, including dietary modulation, prebiotics, and lifestyle-based microbiome interventions, as well as therapeutic approaches such as microbiota-targeted treatments aimed at mitigating neuroinflammation and disease progression.",

Prior work has advanced redox dysregulation, neuroinflammation, and NMDA receptor hypofunction as a putative central hub in schizophrenia. This narrative review proposes an evidence-weighted redox-mitochondria-immune framework that integrates peripheral biomarkers, magnetic resonance spectroscopy, postmortem findings, and preclinical mechanisms while explicitly distinguishing established observations from candidate pathways. Existing studies support increased oxidative damage and altered antioxidant buffering in schizophrenia, particularly involving the glutathione system. However, these abnormalities are neither uniform across disease stages nor equally represented across patient subgroups, and may be markedly prominent only in certain biological subgroups. Mechanistically, redox imbalance may interact with mitochondrial bioenergetic deficits and innate immune signaling; however, pathway-specific links such as cGAS-STING activation, nitrosative/peroxynitrite stress, and GPx4-ferroptosis should currently be treated as testable extensions rather than validated human mechanisms in schizophrenia. Importantly, the pathological consequences of oxidative stress are unlikely to be cell-type neutral. Parvalbumin-positive interneurons and oligodendrocyte lineage cells are more vulnerable because of their high metabolic load, limited antioxidant buffering capacity, and lipid/iron-related susceptibility, thereby providing a mechanistic bridge to excitation-inhibition imbalance, myelin abnormalities, and reduced circuit synchrony. Microglial redox-inflammatory signaling may further exacerbate these processes. On the basis of this framework, we argue that the key for future research is not to continue demonstrating the universality of oxidative stress, but to improve the translational efficiency. Biomarker-guided stratification, stage-sensitive study designs, and cell-type-informed therapeutic strategies may therefore provide a more productive path toward redox-targeted interventions in schizophrenia.",

Mitochondrial non-coding RNAs (mt-ncRNAs) form a regulatory network critical for mitochondrial function. Among them, mitochondrial-encoded circular RNAs (mecciRNAs) and mitochondrial double-stranded RNAs (mt-dsRNAs) are research hotspots. mecciRNAs protect the heart by assisting protein import and regulating mitochondrial pores and ROS; their degradation worsens HF, while exogenous supplementation alleviates injury. mt-dsRNAs arise from aberrant mitochondrial transcription and contribute to myocardial injury and remodeling via MAVS, cGAS-STING, and PNPT1 pathways.

This study investigates whether glycemic control modulates the relationships among glymphatic dysfunction, cortical thinning, and cognition in T2DM, with a focus on whether glymphatic impairment is associated with chronic hyperglycemia-related neurostructural decline. T2DM patients were stratified by glycemic control (Hemoglobin A1c\u2009<\u20097.5% vs. \u2265 7.5%). All participants underwent neuropsychological assessments and magnetic resonance imaging (MRI) to quantify cortical thickness, choroid plexus volume (CPV), perivascular space (PVS) volume, and the diffusion tensor image analysis along the perivascular space (DTI-ALPS) index. Group comparisons, Spearman correlations, and mediation analyses were used to examine the pathways linking glycemic control, glymphatic function, and cortical structure. A total of 54 poorly controlled T2DM patients, 38 well-controlled T2DM patients, and 99 healthy controls were included. Poorly controlled T2DM patients exhibited worse cognitive performance compared with healthy controls. Both T2DM groups showed reduced cortical thickness in the insula, fusiform gyrus, and supramarginal gyrus relative to healthy controls, with insular atrophy significantly associated with enlarged CPV. Markers of glymphatic dysfunction, including enlarged CPV, increased PVS volume, and reduced DTI-ALPS index, were most pronounced in the poorly controlled T2DM group. Cortical thickness and glymphatic measures each correlated with cognitive performance. Mediation analysis indicated that CPV showed associations consistent with a mediating role in the relationship between HbA1c and left insular cortical thinning. Compared with other subgroups, in the poorly controlled T2DM group, glymphatic changes were more pronounced, and the glymphatic-cognitive associations were more evident. Furthermore, CPV showed associations consistent with a mediating role in the relationship between hyperglycemia and cortical thinning in T2DM patients. These findings suggest that the glymphatic system may serve as an associative link between systemic metabolic dysregulation and structural neurodegeneration, offering potential imaging biomarkers for early neurological risk assessment in T2DM.",

Annualized relapse rate (ARR) during IL-6RB therapy, time to next relapse after treatment initiation, and adverse events. Outcomes were compared with the IVIG cohort using inverse probability of treatment weighting (IPTW) adjusted for age, sex, prior ARR, and concomitant therapies. A total of 116 patients with MOGAD (89% relapsing) receiving IL-6RB (tocilizumab, 104 [90%] and satralizumab, 12 [10%]) were included; overall, 60.3% were female, 39.7% were male, and 18% were younger than 18 years. The median (IQR) IL-6RB treatment follow-up was 1.4 (0.7-2.5) years and 23 relapses occurred during 241.8 person-years of IL-6RB therapy. The ARR decreased from 0.64 (95% CI, 0.58-0.70) for relapsing MOGAD before IL-6RB to 0.09 (95% CI, 0.06-0.14) during IL-6RB treatment (incidence rate ratio, 0.08; 95% CI, 0.04-0.16). Adverse events occurred in 58 patients (50%), most commonly mild infections, although 10 (9%) had severe infections. In the IVIG cohort (n\u2009=\u200959), 30 relapses occurred over 133.8 person-years (ARR, 0.22; 95% CI, 0.15-0.32). After IPTW, IL-6RB was associated with a lower hazard ratio (HR) than the group who underwent IVIG therapy less than 1 g/kg every 4 weeks (HR, 4.5; 95% CI, 2.0-9.8), with no significant difference vs the group who underwent IVIG 1 g/kg or more every 4 weeks (HR, 2.0; 95% CI, 0.8-4.5). In this multicenter observational cohort, IL-6RB use in MOGAD was associated with low relapse rates and a favorable safety profile, though severe infections occurred occasionally. Relapse rates were lower than the group who underwent IVIG less than 1 g/kg every 4 weeks but not significantly different from the group who underwent IVIG 1 g/kg or more every 4 weeks. This supports IL-6RB as a potential relapse-prevention therapy in MOGAD; the wide availability and relative affordability of tocilizumab may enable broad global use.",

However, the application of natural exosomes is constrained by their poor targeting ability. Herein, we report a novel drug delivery system (P2-Exo-Cur) constructed by engineering exosomes to display the P2 peptide on their surface, thereby enabling targeted delivery of curcumin to microglia. Our results revealed that P2-Exo-Cur possesses a nanoscale membrane structure and can efficiently deliver curcumin to microglia both in vitro and in vivo. This technology provides a microglia-targeted delivery approach for anti-inflammatory agents such as curcumin, while overcoming the undesirable off-target effects that limit their efficacy. Furthermore, treatment of lipopolysaccharide (LPS)-induced inflammatory BV2 cell models with P2-Exo-Cur significantly suppressed the polarization of BV2 cells toward the M1 phenotype, as well as the secretion of pro-inflammatory cytokines. Finally, we also validated the excellent therapeutic potential of this technology in the 5xFAD mouse model. In conclusion, in this study, we for the first time constructed engineered exosomes that can specifically bind to the NCAM protein on microglia to achieve precise delivery of curcumin by expressing the P2 peptide on their surface, exerting beneficial effects in AD treatment without causing significant adverse effects.

However, the integration of different comorbid stress factors into a persistent and organ-specific inflammatory network remains unclear. Under the background of HFpEF, mitochondrial DNA (mtDNA) may not only play a role as a damage-associated molecular pattern (DAMP), but also act as a cross-organ inflammatory signal, linking the comorbid-driven mitochondrial stress with endothelial dysfunction, myocardial remodeling, and extracardiac organ involvement. Under the influence of HFpEF-related stress factors, including aging, obesity, diabetes, hypertension, and renal dysfunction, mtDNA may undergo oxidation and structural remodeling and be released in the form of free DNA, extracellular vesicle (EV)-related DNA, or neutrophil extracellular trap-related DNA. These mtDNA signals may activate the nucleic acid sensing pathways mediated by TLR9 and cGAS-STING, and promote the activation of downstream NLRP3 inflammasomes in endothelial cells, cardiomyocytes, fibroblasts, immune cells, and extracardiac tissues, thereby promoting IL-6/TNF production, type I interferon signaling, inflammasome activation, and self-amplifying inflammatory circuits related to the progression of HFpEF. Within this framework, HFpEF can be understood as a cross-organ network reconfiguration state, where mtDNA-related inflammatory signals may lead to abnormal information flow, especially in the internal phenotype characterized by metabolic stress, age-related mitochondrial damage, renal dysfunction, and systemic inflammation. The coupling between mtDNA generation, transmission, and decoding may amplify endothelial dysfunction, myocardial stiffness, fibrosis, and phenotypic-specific inflammatory remodeling; however, these processes occur within a broader pathological biology background of HFpEF, which also includes mechanisms independent of mtDNA, such as impaired NO-cGMP-PKG signaling, low phosphorylation of myosin, vascular stiffness, renal dysfunction, neurohumoral activation, and extracellular matrix remodeling. Therefore, this article proposes that mtDNA efflux is an inflammation amplifier that depends on the phenotype and disease stage, rather than being a universal or unique mechanism for explaining all HFpEF phenotypes. The existing evidence does not yet prove that mtDNA efflux is the main causal driver of HFpEF; instead, its position in the temporal sequence and causal relationship still needs to be verified in longitudinal studies and intervention studies specific to HFpEF.",

To address this cognitive bottleneck, this paper proposes the conceptual framework of \"cGAS-STING pathway-guided signal flow.\" It attributes pathway outcomes to multi-level fine-tuning, aiming to decipher initial immunogenic/pathogenic signals in the upstream phase based on intensity, duration, and origin. It elucidates how the STING protein, as a central hub, integrates and programs signals through a complex network of post-translational modifications at the midstream, thereby determining whether downstream effector branching favors the IFN-I-mediated antitumor axis or the NF-\u03baB-driven pro-metastatic inflammatory axis. Based on this framework, this paper examines the key checkpoints at each level to explore in depth how to precisely regulate the cGAS-STING signaling pathway in order to maximize antitumor immune responses while mitigating potential risks of metastasis. This navigational framework clarifies signal branching mechanisms between the IFN-I antitumor axis and the NF-\u03baB metastasis-promoting axis in breast cancer, identifies key nodes in signal branching, and evaluates the STING regulatory characteristics of various molecular subtypes. This provides both theoretical and practical foundations for signal reprogramming interventions, patient stratification, and the optimization of combination therapies.",

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.",

Microglia, the brain's resident immune cells, centrally regulate AD pathophysiology. Recent studies have highlighted microglial mitophagy as an important interface linking mitochondrial quality control to innate immune responses.Intact mitophagy facilitates the timely clearance of damaged mitochondria, thereby limiting the release of mitochondrial DAMPs (e.g., mtDNA and mtROS) and helping restrain aberrant activation of the cGAS-STING pathway and the NLRP3 inflammasome.In the AD pathological milieu, however, factors including A\u03b2 deposition, tau pathology, and genetic risk variants such as TREM2 and APOE4 disrupt mitophagy at multiple levels-from initiation and recognition to lysosomal degradation. This review systematically summarizes the molecular regulatory network of microglial mitophagy, with a particular focus on the mechanisms by which AD-associated pathological factors impair this process. We further discuss potential mechanisms through which mitophagic dysfunction may contribute to the amplification of neuroinflammation, including the release of mitochondrial DAMPs, the reprogramming of TBK1 signaling, and intercellular interactions. Finally, we outline current therapeutic strategies aimed at restoring mitophagy and discuss their potential to modulate neuroinflammatory responses and AD-related pathological processes, while highlighting the challenges and future directions in this emerging field.",

In this study, a 59,319-sequence peptide library was screened against STING by molecular docking, and four top-ranked peptides were selected for evaluation. MST analysis demonstrated that Peptides 1-4 bound to recombinant STING, with Peptide-1 showing the highest affinity (Kd = 0.15\u2009\u00b1\u20090.01\u2009\u03bcM). Docking and simulation analyses suggested that binding was mediated by hydrogen bonding and hydrophobic contacts. Molecular dynamics, MM/PBSA, and free energy landscape analyses suggested stable binding with favourable calculated energetics. Peptide-1 showed no apparent cytotoxicity up to 10\u2009\u03bcM in RAW264.7 macrophages and primary BMDMs, while dose-dependently reducing cGAMP-induced IFN-\u03b2 and IL-6 expression at both protein and mRNA levels. This inhibitory effect was accompanied by reduced STING and IRF3 phosphorylation. Collectively, these findings suggest that Peptide-1 may bind STING and attenuate cGAMP-induced IFN-\u03b2 and IL-6 expression.",

Notably, the clinical efficacy of current interventions is severely restricted by post-ischemic neuroinflammation. Cerebral ischemic injury prompts an inflammatory surge mediated by the cGAS-STING signaling cascade, a process initiated by the recognition of aberrantly localized cytosolic DNA. Three-prime repair exonuclease 1 (TREX1), a cytosolic DNA exonuclease, negatively regulates STING signaling; however, efficient delivery of TREX1 to the ischemic brain remains a major challenge. Here, we engineered mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) as carriers for TREX1 delivery. This was accomplished by using a palmitoylation signal-fused construct (PALM-TREX1), which enables efficient loading of the protein into extracellular vesicles. The C1C2 domains of lactadherin and the RGD-4C peptide were combined into a single recombinant fusion protein, enabling EV surface functionalization for enhanced ischemic targeting via phosphatidylserine interaction. In a mouse model of middle cerebral artery occlusion (MCAO), RGD-modified TREX1-loaded EVs (RGD-EV-TREX1) preferentially accumulated in ischemic regions, suppressed STING pathway activation, and reduced microglial activation and pro-inflammatory cytokine expression. The reduction in neuronal DNA damage and apoptosis ultimately facilitated improved neurological functional recovery, positioning RGD-EV-TREX1 as a promising cell-free therapeutic strategy for ischemic stroke.",

The main and direct nerve connection between the gut and the brain is the gastrointestinal vagus nerve, which is activated by pathogenic bacteria. In the course of inflammatory bowel diseases, microbial dysbiosis and intestinal inflammation compromise the epithelial barrier, leading to increased levels of circulating pro-inflammatory cytokines, which cross the blood-brain barrier and trigger neuroinflammation. Restoring microbiota balance and effective delivery of neuroactive metabolites to the brain is therefore expected to attenuate both neuroinflammation and neuropsychiatric symptoms. This article highlights some recent manuscripts that take advantage of nanomedical tools to achieve modulation of the gut-brain axis responses, thus developing promising therapies for inflammatory and neurodegenerative disorders.",

Central to this inflammatory milieu is pyroptosis, a highly inflammatory form of programmed lytic cell death mediated by gasdermin proteins. This comprehensive review provides an in-depth synthesis of the cellular and molecular mechanisms underlying pyroptosis in AD. We detail the distinct roles of microglia as primary initiators responding to amyloid-beta (A\u03b2) and tau aggregates, alongside the specific vulnerabilities of neurons facing oxidative stress, astrocytes impacting metabolic support, and endothelial cells whose pyroptotic death contributes directly to blood-brain barrier disruption. At the molecular level, the priming and activation of the NLRP3 and NLRP1 inflammasomes by diverse triggers, including classical markers like A\u03b2, environmental neurotoxicants and metabolic stressors, converge on caspase-1 and caspase-8 activation. This cascade culminates in gasdermin D (GSDMD) and gasdermin E (GSDME) pore formation, leading to cellular lysis and the massive release of pro-inflammatory cytokines such as IL-1\u03b2 and IL-18. Furthermore, this paper explores the emerging and critical concept of PANoptosis, highlighting the intricate crosstalk between pyroptosis, apoptosis, and necroptosis within PANoptosome complexes triggered by mitochondrial dysfunction. We evaluate current and prospective therapeutic strategies, ranging from multi-target natural and traditional herbal remedies to advanced nanomedicine, synthetic small molecules, and epigenetic gene therapies. By integrating insights from blood-based pyroptosis-associated molecular signatures and advanced targeted drug delivery systems, we emphasize the critical need for personalized, multi-targeted approaches to successfully harness pyroptosis modulation in the clinical management and treatment of AD.",

However, the clinical application of STING agonists is severely hindered by the tumor immunosuppressive microenvironment (TIME) and non-specific delivery. Herein, a biomimetic phototheranostic nanotrident (mPDXZ@M) is meticulously designed through hierarchical engineering of mesoporous polydopamine (mPDA). Upon near-infrared laser irradiation, mPDA-mediated photothermal therapy (PTT) evokes robust cell apoptosis and immunogenic cell death, thereby ameliorating the TIME and triggering ATP secretion for Zn2+ and 5,6-dimethylxanthenone-4-acetic acid (DMXAA) release. The Zn2+ then inhibits glycolysis, lowering heat shock protein 70 and sensitizing tumors to PTT. Ultimately, DMXAA activates the cGAS-STING pathway to promote dendritic cell maturation and cytotoxic T cell infiltration, collectively driving potent tumor regression. Overall, this tailor-engineered phototheranostic nanotrident exemplifies a transformative strategy for self-amplified photo-immunometabolic therapy, enabling effective immune priming and pronounced tumor suppression.",

Pemetrexed, an antifolate chemotherapeutic agent, has documented immunomodulatory effects in \u03b1\u03b2 T-cell settings; however, its impact on \u03b3\u03b4 T-cell antitumor responses remains insufficiently defined. Here, V\u03b39V\u03b42 T cells were isolated and expanded from healthy-donor peripheral blood mononuclear cells (PMBCs) and co-cultured with non-small cell lung cancer (NSCLC) cells with or without pemetrexed pretreatment. Pemetrexed significantly enhanced \u03b3\u03b4 T cell-mediated cytotoxicity compared with either treatment alone. Mechanistically, pemetrexed increased the expression of NKG2D ligands, including MHC class I chain-related proteins A/B (MICA/B) and UL16-binding proteins (ULBPs), through the ataxia-telangiectasia mutated (ATM)-stimulator of interferon genes (STING)-nuclear factor-\u03baB (NF-\u03baB) signaling axis. ATM activation triggered cyclic GMP-AMP synthase-independent STING signaling and preferentially activated NF-\u03baB rather than interferon regulatory factor 3 (IRF3), thereby promoting transcriptional upregulation of NKG2D ligands and improving tumor recognition by \u03b3\u03b4 T cells. Consistent with the cell-line findings, pemetrexed increased MICA/B and ULBP2/5/6 expression in NSCLC patient-derived organoids. Furthermore, in an in vivo NSCLC animal model, combined pemetrexed and adoptive \u03b3\u03b4 T-cell therapy suppressed tumor growth more effectively than either treatment alone and was accompanied by increased NKG2D ligand expression. Collectively, these findings reveal a tumor-sensitizing mechanism by which pemetrexed potentiates \u03b3\u03b4 T-cell antitumor function and support combining pemetrexed with \u03b3\u03b4 T cell-based immunotherapy for NSCLC.",

The stimulator of interferon genes (STING) pathway is emerging as a central driver of microglial activation and inflammatory damage. However, therapeutic strategies targeting this pathway are limited. We investigated the neuroprotective effects of senegenin, a bioactive natural compound, in a rat middle cerebral artery occlusion/reperfusion (MCAO/R) model and N9 microglia subjected to oxygen-glucose deprivation/reoxygenation (OGD/R). Behavioral, histological, and biochemical analyses were performed to assess neurological outcomes, infarct volume, microglial activation, and neuroinflammatory response. Mechanistic studies evaluated the effects of senegenin on STING-TBK1-IRF3 signaling, NF\u03baB-dependent NLRP3 inflammasome activation, pyroptosis, and apoptosis. Molecular docking, dynamics simulations, and pharmacological validation with the STING agonist DMXAA were used to confirm direct STING inhibition. Senegenin treatment significantly improved neurological outcomes, decreased infarct volume, and preserved cortical and hippocampal neurons. It attenuated oxidative stress, reduced DNA damage, and inhibited microglial activation. Mechanistically, senegenin suppressed STING activation and downstream phosphorylation of TBK1 and IRF3, blocked NF-\u03baB/NLRP3-mediated pyroptosis, and inhibited apoptotic death by modulating Bcl2 and BAX expression. Molecular docking predicted stable binding of senegenin to STING, and DMXAA experiments confirmed direct inhibition of STING signaling as the mechanistic basis of its neuroprotective effects. This study demonstrates that senegenin confers potent neuroprotection in ischemic stroke by attenuating regulated cell death pathways through direct inhibition of STING, highlighting its ability as a promising therapeutic candidate for STING-targeted interventions in ischemic stroke and related neuroinflammatory disorders.",
        "42449389": "ID: 42449389\nTitle: Ferritin-ApoE nanocarrier for targeted therapy of neuromyelitis optica spectrum disorder in mice.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is a chronic inflammatory autoimmune disease affecting the central nervous system (CNS), characterized by anti-aquaporin 4 (AQP4) antibody-mediated damage to astrocytes, resulting in subsequent demyelination. Our prior work identified the protective effects of the apolipoprotein E130-149 (ApoE130-149) peptide in NMOSD mice by promoting astrocyte-microglia intercellular communication. However, its therapeutic potential is restricted due to the limited penetration of the blood-brain barrier (BBB) with systemic administration. Here, we designed a heavy-chain ferritin (HFn)-based nanocarrier containing the ApoE130-149 peptide (HFn-ApoE130-149), specifically engineered for CNS delivery. HFn-ApoE130-149 was constructed through genetic engineering by fusing the coding sequence of HFn with that of the ApoE130-149 peptide in a recombinant plasmid. An acute NMOSD mouse model was induced by transcranial co-injection of AQP4-IgG and human complement (hC) into the brain. The distribution of Cy5.5-labeled HFn-ApoE130-149 post intravenous injection was tracked using in vivo fluorescence imaging to confirm its presence in the brain and peripheral organs. Lesions in the brain were quantified using T2-weighted 7 Tesla magnetic resonance imaging (7T-MRI). Neuropathological features of NMOSD were evaluated by immunostaining of brain sections. Neuroinflammation and immune cell infiltration were analyzed via flow cytometry. The key signaling pathways regulated by HFn-ApoE130-149 were investigated through Western blot (WB) analysis. The interaction between HFn-ApoE130-149 and its receptors was validated through co-immunoprecipitation and visualized on microglia using proximity ligation assay (PLA). Finally, the therapeutic effect on spatial learning and memory was evaluated using the Morris water maze (MWM) test. The HFn-ApoE130-149 effectively crossed the BBB, attenuated lesion progression and demyelination, as well as preserved AQP4 expression and astrocytic integrity in NMOSD mice. The treatment induced a spatial and phenotypic restructuring of the astrocytic response, notably reducing excessive astrocyte accumulation around lesions while encouraging a proliferative and reparative phenotype. Furthermore, HFn-ApoE130-149 influenced microglial polarization towards an anti-inflammatory state, reducing infiltration of peripheral immune cells. Mechanistically, HFn-ApoE130-149 exerted its anti-inflammatory effects through the low-density lipoprotein receptor-related protein 1 (LRP1) -nuclear factor kappa B (NF-\u03baB) signaling axis in microglia. Functional binding of HFn-ApoE130-149 to LRP1 suppressed inhibitor of NF-\u03baB (I\u03baB\u03b1) phosphorylation, thereby inhibiting NF-\u03baB nuclear translocation and the subsequent release of pro-inflammatory cytokines, including interleukin-1 beta (IL-1\u03b2), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-\u03b1). Knocking down LRP1 reversed these effects, highlighting the importance of the LRP1-NF-\u03baB signaling axis in the nanotherapeutic's efficacy. Treatment with HFn-ApoE130-149 improved spatial learning and rescued memory deficits in NMOSD mice. This study demonstrates that the engineered nanodrug HFn-ApoE130-149 is a promising targeted therapy for alleviating NMOSD pathology by enhancing BBB penetration and suppressing neuroinflammation through the LRP1-NF-\u03baB signaling axis.",

While immune checkpoint blockade (ICB) therapy has transformed treatment for mismatch repair-deficient (MMRd)/microsatellite instability-high (MSI-H) tumors, most CRC cases are mismatch repair-proficient (MMRp)/microsatellite-stable (MSS) and derive little to no benefit from current immunotherapy regimens. Tumor-associated macrophages (TAMs) constitute a significant component of the tumor microenvironment (TME) and exhibit a phenotypic gradient between pro-inflammatory (M1-like) and anti-inflammatory, immunosuppressive (M2-like) states. Although their polarization status is increasingly recognized as a key modulator of immunotherapy efficacy in CRC, a comprehensive synthesis of the literature regarding macrophage polarization and its relevance to improving CRC immunotherapy remains lacking. Methods: A systematic literature search was conducted across PubMed, EMBASE, and ScienceDirect from inception to December 2025 using terms encompassing macrophages, immunotherapy, immune checkpoint expression, colorectal cancer, and microsatellite stability status. Title, abstract, and full-text screening were performed independently by multiple authors. Sixty-five studies were included following PRISMA guidelines. The protocol was prospectively registered on PROSPERO (ID: CRD420251244320). Results: Three key themes were identified: (1) macrophage-mediated mechanisms of resistance to ICB, including M2 polarization driven by the PI3K\u03b3, STAT3, mTOR, and SIRT-1 axes, immunosuppressive cytokine production (IL-10, TGF-\u03b2), and altered immune checkpoint ligand expression; (2) macrophage polarization status and associated biomarkers as prognostic indicators of therapeutic response; (3) emerging macrophage-targeted therapeutic strategies in ongoing clinical trials, including CSF1R inhibitors, CD40 agonists, CD47/SIRP\u03b1 blockade, and STING agonists. Conclusions: TAM polarization is a critical determinant of immunotherapy resistance and patient prognosis in CRC. Macrophage-targeted strategies, particularly M2-to-M1 repolarization approaches used in combination with existing ICB regimens, represent a promising avenue for expanding immunotherapy efficacy beyond MSI-H disease. Further translational research and randomized controlled trials are needed to validate these targets clinically.",

While the survival benefit of TTFields was established by the EF-14 phase III trial, their biological effects extend well beyond the canonical anti-mitotic mechanism and encompass extensive interactions with the GBM tumor microenvironment (TME). This review provides an integrated mechanistic analysis of TTFields-TME interactions in GBM, with a distinctive focus on their convergence with radiotherapy. We examine how TTFields activate innate immune sensing through cGAS/STING and AIM2 inflammasome pathways, drive immunogenic cell death, reprogram tumor-associated macrophages, and prime adaptive T cell responses. We further address TTFields effects on glioma stem cells, blood-brain barrier permeability, and intracellular signaling governing invasion, angiogenesis, and autophagy. Critically, we develop the mechanistic and clinical case for TTFields-radiotherapy combinations, highlighting convergent mechanisms of DNA repair impairment, mitotic catastrophe, and innate immune activation. Practical considerations for concurrent clinical implementation are discussed alongside a research agenda centered on optimal timing, hypofractionation, and predictive biomarkers. Available evidence-largely preclinical-suggests that TTFields may act as a TME-remodeling platform whose potential is most likely to be realized through mechanistically informed combinations.",

Although early antimicrobial therapy, source control, hemodynamic resuscitation, and organ support remain the foundations of care, these approaches do not directly reverse the cellular mechanisms that connect systemic inflammation to multi-organ failure. Mitochondrial dysfunction has emerged as a central mechanism linking impaired oxygen utilization, oxidative and nitrosative stress, immune-cell metabolic reprogramming, inflammatory amplification, and organ injury. During sepsis, inflammatory mediators, nitric oxide, microcirculatory abnormalities, calcium dysregulation, and metabolic stress converge on mitochondria, impairing oxidative phosphorylation and promoting mitochondrial reactive oxygen species/reactive nitrogen species (ROS/RNS) generation. When mitochondrial quality-control programs, including fission, fusion, mitophagy, and mitochondrial biogenesis, fail to restore network integrity, damaged mitochondria accumulate and become persistent sources of oxidative stress and danger signals. Mitochondrial damage-associated molecular patterns, particularly mitochondrial DNA, oxidized mitochondrial DNA, cardiolipin, ATP, and N-formyl peptides, activate innate immune pathways such as TLR9-MyD88-NF-kappaB, the NLRP3 inflammasome, and cGAS-STING signaling. In parallel, mitochondrial metabolism shapes macrophage activation, neutrophil function, T-cell competence, pyruvate-lactate handling through the pyruvate dehydrogenase complex, and the transition between hyperinflammation and immunosuppression. Clinical translation remains challenging because sepsis is biologically heterogeneous and mitochondrial dysfunction is dynamic, tissue-specific, and influenced by disease stage. This review synthesizes current knowledge on mitochondrial dysfunction in sepsis, emphasizing oxidative and nitrosative stress, mitochondrial quality control, mitochondrial damage-associated molecular pattern (DAMP) signaling, immunometabolism, organ-specific injury, candidate biomarkers, clinical translational strategies for mitochondria-targeted therapy, and future approaches based on multi-omics and artificial intelligence-assisted patient stratification. We argue that future therapeutic development should move beyond nonspecific antioxidant supplementation toward time-sensitive, phenotype-informed, and biomarker-guided mitochondrial medicine.",

In this study, we proposed a system-level ionic homeostasis framework for MDD. In this model, genetic susceptibility, chronic stress, metabolic burden, and neuroinflammation converge in neuronal and glial ion-channel systems, disrupting calcium, potassium, chloride, and purinergic homeostasis. These disturbances alter intrinsic excitability, synaptic integration, inhibitory tone, glial buffering, and neuron-glia signaling, thereby promoting excitation-inhibition imbalance, impaired plasticity, and corticolimbic network instability. We reviewed the evidence implicating the CACNA1C/Cav1.2, TREK-1, KCNQ, NKCC1/KCC2, HCN, transient receptor potential/acid-sensing ion channels, and glial mediators, including P2X7R, Kir4.1, and AQP4. We also discuss how ketamine-related mechanisms, chloride-restoring strategies, anti-inflammatory ion channel targeting, neuromodulation, EEG biomarkers, and AI/multiomics approaches support mechanism-informed precision therapeutics. MDD could be conceptualized as a distributed failure of ionic homeostasis that links neuroinflammation, E/I imbalance, network instability, and impaired adaptive plasticity.",

This systematic review aimed to synthesize current evidence on cerebrospinal fluid (CSF) proteomic biomarkers in iNPH and to identify molecular patterns with diagnostic and prognostic relevance. A PRISMA-guided search of PubMed, Web of Science, and Google Scholar identified 14 eligible studies comprising 1171 iNPH patients. Proteomic analyses revealed substantial heterogeneity in study design and detected proteins; however, consistent patterns emerged. iNPH is associated with upregulation of inflammatory and extracellular matrix-related proteins and relative downregulation of synaptic and neuronal markers. Neurodegenerative proteins, including amyloid-\u03b2, tau, and neurofilament light chain, demonstrated value in differentiating iNPH from comorbid neurodegenerative diseases and in predicting response to ventriculoperitoneal shunting (VPS). These findings support a multifactorial model of iNPH involving impaired glymphatic clearance, neuroinflammation, blood-brain barrier dysfunction, and mechanical axonal stress. Multidimensional biomarker profiles, rather than single proteins, appear to provide the greatest clinical utility, highlighting the need for standardized proteomic panels and integrative predictive models. However, given the substantial heterogeneity of the included studies and the predominantly exploratory nature of current proteomic evidence, the identified proteins should be interpreted as candidate biomarkers rather than clinically validated diagnostic or prognostic tools. Multidimensional biomarker profiles appear biologically plausible and may offer greater explanatory value than single proteins, but their clinical utility requires validation in standardized prospective cohorts. The authors therefore propose a conceptual iNPH proteomic \"Vulnerability Model\" integrating CSF biomarkers to reflect the balance between reversible and irreversible pathology; this is currently a hypothetical model that requires rigorous statistical and clinical validation through large-scale prospective cohort studies before it can fulfill its potential for improving patient stratification and prediction of postoperative outcomes.",

The phenotypic spectrum of diseases linked to DNAJC30 includes isolated optic neuropathy, Leigh syndrome spectrum (LSS), and atypical LHON-plus. Case description: Here, we report a 13-year-old boy presenting symptoms of area postrema syndrome (APS), with recurrent vomiting, vertigo, nystagmus, and subacute visual deterioration with central scotoma. Ophthalmological examination revealed bilateral papilledema with telangiectatic vessels, while visual evoked potentials demonstrated severe bilateral optic pathway dysfunction. Brain magnetic resonance imaging (MRI) showed T2/FLAIR hyperintense lesions involving the area postrema and enhancement of the optic nerves, strongly suggesting seronegative neuromyelitis optica spectrum disorder (NMOSD). Extensive immunological and cerebrospinal fluid studies, including anti-aquaporin-4 (AQP4) and anti-MOG antibodies, were negative. High-dose corticosteroids and intravenous immunoglobulins resulted in only transient and incomplete improvement, followed by further visual decline. Additionally, laboratory tests detected elevated lactate plasma levels. Hence, whole-exome sequencing was performed, which identified a homozygous pathogenic DNAJC30 c.152A>G, p.(Tyr51Cys) variant, associated with LHONAR1. After initiation of idebenone therapy, the patient showed significant improvement in visual function, normalization of lactate levels, and complete resolution of the brainstem lesions on follow-up MRI. Conclusions: This case further expands the neuro-ophthalmic spectrum associated with DNAJC30 variants and suggests that DNAJC30-related disease may closely mimic seronegative NMOSD. We highlight that early genetic diagnosis is essential, as recognition of this mitochondrial etiology enables targeted therapy and may substantially improve clinical outcomes.",

Targeting dysregulated PI3K/Akt/mTOR signaling and triggering anti-tumor immunity represent promising strategies for TNBC therapy. In this study, we report the discovery of a series of novel chromone derivatives as potent mTOR inhibitors by artificial intelligence-assisted drug design and structure-based drug design. The optimal compound, MT-44, was a highly selective mTOR inhibitor and showed no obvious binding activity to a broad panel of 200 kinases, and it exhibited nanomolar-level mTOR inhibitory and anti-TNBC cells proliferative activities. MT-44 effectively blocked the PI3K/Akt/mTOR signaling pathway and exerted robust anti-tumor efficacy in an MDA-MB-231 xenograft mouse model. Furthermore, MT-44 activated pattern recognition receptor TLR2 and upregulated the cGAS/STING signaling pathway, and reshaped the tumor microenvironment, thereby enhancing the tumor immune landscape. Collectively, our findings highlighted MT-44 as a highly selective and potent mTOR inhibitor with dual-targeted therapeutic and immunomodulatory effects, offering an appealing strategy for TNBC.",

Here we reveal the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) pathway as a key mediator of innate immune activation following intracranial AAV administration. Through comparative analyses in genetic and pharmacological intervention models, we demonstrate that STING signaling mediates key neuroinflammatory sequelae including glia reactivation, cytotoxic T cell infiltration, and neuronal injury. Mechanistically, microglia serve as the predominant sentinels detecting AAV immunogenicity via cGAS-STING activation. Therapeutic inhibition of this pathway by either microglia depletion or antagonism of STING by small molecules significantly mitigates high-dose AAV9-induced neurotoxicity while enhancing transgene delivery efficacy. Our work delineates a unified mechanistic framework linking AAV-triggered DNA sensing to neuroinflammatory pathology, and provides two clinically actionable approaches to decouple therapeutic gene delivery from detrimental immune activation in nervous system targeted gene therapy.",
        "42454062": "ID: 42454062\nTitle: Iron overload disrupts bone homeostasis via TfR1-dependent ferroptosis and cGAS/STING-driven pyroptosis in pyogenic spondylitis.\nAbstract: Pyogenic spondylitis (PS) accompanies with diverse destruction, especially the subsequent bone destruction, which leads to spine instability and severe neurological disability. However, the mechanism underlying bone loss induced by infection has not been elucidated. In this study, we aimed to reveal a novel mechanism of bone destruction in PS. To certify the involvement of iron overload in PS-induced bone loss, vertebrae samples were collected and evaluated from patients with PS. Next Staphylococcus aureus (S. aureus, ATCC 25923) was used to induce bone infection in vivo and in vitro, and relevant markers were investigated. Then, experiments using siRNA targeting transferrin receptor-1 (TfR1), an iron chelator (DFO), and the TfR1 inhibitor Ferristatin II were conducted to investigate the role of TfR1-induced iron overload and ferroptosis in PS-induced bone destruction. Infected vertebral specimens from PS patients showed iron overload and increased TfR1 expression, which was also observed in S. aureus -infected MC3T3-E1 cells. Excessive iron leads to osteoblast ferroptosis and osteogenic activity via iron overload and oxidative stress injury, which was inhibited by TfR1 siRNA or DFO. Meanwhile, iron overload promoted mtDNA leakage and activated the cGAS/STING pathway, contributing to NLRP3-associated pyroptosis and impaired osteogenesis. In addition, S. aureus -induced iron overload in osteoclasts promoted osteoclastogenesis, which was also ameliorated by TfR1 siRNA or DFO. In vivo, Ferristatin II reduced iron deposition, suppressed TfR1 expression, and preserved trabecular architecture in PS rats. Our research indicates that S. aureus infection triggers iron overload in infected bone tissue via the promotion of TfR1 expression, finally contributing to osteoblast ferroptosis and bone destruction. Targeting TfR1-mediated iron influx and ferroptosis is a novel therapeutic strategy for the treatment of bone loss induced by PS.",

Although several therapeutic options are available, many patients continue to experience persistent visual impairment and headaches, suggesting that key disease mechanisms remain poorly understood. Emerging evidence implicates dysfunction of the glial neurovascular unit (gNVU) in the pathogenesis of IIH. To systematically evaluate the association between alterations of gNVU-related proteins, specifically aquaporin-4, glial fibrillary acidic protein, fibrinogen, and neurofilament light chain, with the risk of IIH. A comprehensive literature search of PubMed, EMBASE, Cochrane Library, Scopus, and Web of Science was conducted through August 2025. Studies comparing patients with IIH to control participants and reporting gNVU-related biomarkers in cerebrospinal fluid, plasma, serum, or brain tissue were included. Data extraction and quality assessment were performed independently using the Newcastle-Ottawa Scale. Pooled standardized mean differences with 95% confidence intervals were calculated using random-effects models. Ten studies comprising 327 patients with IIH and 216 controls met the inclusion criteria, with seven studies contributing to quantitative synthesis. Levels of CSF Nf-L and plasma fibrinogen were significantly higher in IIH patients, indicating neuroaxonal injury and a hypercoagulable state (Nf-L: SMD=0.78, 95% CI 0.51-1.05; fibrinogen: SMD=0.66, 95% CI 0.08-1.23). Findings for AQP4 and GFAP were inconsistent across studies. Higher BMI was also associated with an increased risk of IIH (SMD=0.80, 95% CI 0.17-1.44). Study quality did not significantly influence effect estimates. Die idiopathische intrakranielle Hypertension ist eine neurologische Erkrankung unklarer \u00c4tiologie, die vor allem junge Erwachsene betrifft.

        "42455155": "ID: 42455155\nTitle: Evaluation of Glymphatic System Activity in Pediatric Wilson Disease Patients Using Diffusion Tensor Imaging Along the Perivascular Space.\nAbstract: Wilson disease is an autosomal recessive disorder of copper metabolism that results in toxic copper accumulation in the liver and brain, thereby causing neurological injury. Previous reports have described astrocyte dysfunction, oxidative stress, glial pathology, and impaired aquaporin-4-mediated water transport in Wilson disease, suggesting a\u00a0potential disruption of glymphatic fluid dynamics. However, glymphatic function has not been quantitatively assessed in this population using diffusion tensor imaging analysis along the perivascular space (DTI-ALPS). This retrospective single-center study aimed to quantify glymphatic system function in pediatric patients with Wilson disease using the DTI-ALPS index. Brain MRI/DTI data (30\u00a0directions, b\u202f=\u20091000\u202fs/mm2) from 43\u00a0patients younger than 18\u00a0years diagnosed according to the Leipzig criteria (2018-2025) were analyzed and compared with 43 age- and sex-matched healthy controls. Neuro-Wilson status was defined by MRI involvement plus neurological symptoms. ALPS indices were derived from regions of interest in the corona radiata and superior longitudinal fasciculus on color-FA maps. The analyses included group comparisons, correlations with clinical variables, and a\u00a0secondary sensitivity ANCOVA adjusted for age and sex to confirm the robustness of group differences despite demographic matching. Right-, left-, and mean ALPS indices were significantly lower in patients with Wilson's disease than in controls, with this group effect persisting after demographic adjustment (F\u202f=\u200913.90, p\u202f<\u20090.001; adjusted means: controls 1.51, WD 1.34, NWD 1.38). ALPS indices did not differ between the WD and NWD subgroups despite higher liver severity scores in the latter. ALPS values did not correlate with liver severity scores, urinary copper, ceruloplasmin or sex. These findings suggest that the DTI-ALPS index may reflect glymphatic system-related processes, as well as disease-related microstructural and perivascular alterations, in pediatric Wilson disease. The DTI-ALPS index may provide complementary, non-invasive imaging information regarding early perivascular microstructural alterations. Prospective multicenter longitudinal studies are warranted to clarify the temporal relationships among ALPS index changes, neurological progression, and treatment response.",
        "42456532": "ID: 42456532\nTitle: Ring-finger protein 5 protects against diabetic kidney disease by targeting and degrading STING.\nAbstract: The stimulator of interferon genes (STING) has been recognized as a pivotal modulator in the pathological progression of diabetic kidney disease (DKD). Ring-finger protein 5 (RNF5) is an important modulator of STING and is implicated in various disease processes. Nevertheless, the function of RNF5/STING axis in the context of DKD has yet to be investigated. This research was undertaken to explore whether RNF5 regulates the progression of DKD through modulation of the STING pathway, as well as to clarify the mechanisms involved. We found that RNF5 levels were significantly reduced in high glucose (HG)-stimulated HK-2 cells and the kidneys of diabetic mice. Upregulation of RNF5 inhibited HG-induced cellular injury, fibrosis, and inflammatory responses, while RNF5 knockdown exacerbated these detrimental effects. Moreover, HG treatment led to increased levels of STING, phosphorylated TBK1, phosphorylated IRF-3, and phosphorylated NF-\u03baB, indicating STING pathway activation. RNF5 overexpression significantly suppressed the activation of the STING pathway induced by HG, whereas RNF5 knockdown enhanced it. Mechanistically, RNF5 promoted the ubiquitination and degradation of STING. Inhibition of STING abolished the exacerbating effect of RNF5 knockdown on HG-induced cellular injury. Animal studies revealed that RNF5 overexpression alleviated kidney damage, fibrosis, and inflammation in diabetic mouse models, concomitantly suppressing STING pathway activation. Collectively, RNF5 inhibits HG-induced tubular cell injury by promoting STING degradation, thereby suppressing STING pathway activation. Targeting RNF5 could be a potentially effective therapeutic approach for DKD.",
        "42456758": "ID: 42456758\nTitle: Syringeable hyaluronic acid-based hydrogel co-loaded with Cisplatin and MSA-2 for enhanced ovarian cancer chemoimmunotherapy.\nAbstract: Low immunogenicity and a prevailing immunosuppressive tumor microenvironment (TME) remain major bottlenecks for ovarian cancer immunotherapy. While plati-num-based chemotherapy can trigger antitumor immunity via immunogenic cell death (ICD), its clinical efficacy is often hampered by the intrinsic immunosuppressive milieu and insufficient drug accumulation at the tumor site following systemic administration. To address these challenges, we fabricated a syringeable hyaluronic acid-based hydrogel co-loaded with Cisplatin (CDDP) and STING agonist MSA-2 (CDDP/MSA-2@Gel) for enhanced localized chemoimmunotherapy. The sustained local release of CDDP and MSA-2 synergistically boost stimulator of interferon genes (STING) pathway activation, thereby eliciting potent type-I-IFN-driven systemic antitumor immune responses and alleviating the immunosuppressive TME. In vivo studies demonstrated that CDDP/MSA-2@Gel treatment significantly inhibits tumor growth in murine ovarian cancer models without systemic toxicity.Collectively, our designed CDDP/MSA-2@Gel represents a safe and potent strategy for enhanced synergistic chemoimmunotherapy, offering significant potential for clinical translation in the treatment of ovarian cancer.",
        "42456899": "ID: 42456899\nTitle: ATR inhibition sensitizes pancreatic cancer cells to cytotoxic and immunogenic effects of X-ray and carbon ion irradiation.\nAbstract: Pancreatic ductal adenocarcinoma (PDAC) remains a clinical challenge characterized by an alarmingly low survival rate. Despite surgical advances and new chemotherapy combinations, currently available treatment fails to improve the overall survival of PDAC patients largely due to an immunosuppressive tumor microenvironment. Radiation can induce cell death and reprogramme the tumor microenvironment by promoting anti-tumor immune response. The cGAS-STING and RIG-I-MAVS pathways are central components of the innate immune system that detect cytosolic nucleic acids and initiate type I interferon production. This study aims to leverage radiation-induced DNA damage together with inhibition of DNA repair and cell cycle checkpoints to potentiate type I interferon response and thereby enhance anti-tumor immunogenicity in PDAC. Two different PDAC cell lines (KRAS wild-type BxPC-3 and KRAS-mutated PANC-1) were used to test two different radiation modalities (X-rays and carbon ions) and regimens (single and hypofractionated dose) in combination with ATR and CHK1 inhibitors as well as the STING agonist diABZI. Cell survival, immunogenic cell death, accumulation of cytosolic dsDNA and micronuclei, gene expression profiles, and STING- and NF-\u03baB-dependent immune signaling were assessed. Immune activation was evaluated by incubating immune cells with supernatants from PDAC cells, followed by analysis of activation markers using spectral flow cytometry. Here we demonstrate that ATR inhibition sensitizes BxPC-3 cells to the cytotoxic effects of radiation and potentiates the immunogenic effects of carbon ions and hypofractionated X-rays (3x8 Gy). Increased accumulation of cytosolic dsDNA and micronuclei was coupled with STING-dependent IFNB1 secretion and genome-wide induction of inflammatory gene expression programs, ultimately resulting in the activation of monocytes. This was not the case for PANC-1 cells, where radiation alone exerted immunosuppressive effects on monocytes. Our results support further evaluation of ATR inhibition in combination with radiotherapy in KRAS wild-type pancreatic cancer.",

BV2 cells were divided into three groups: control group (no treatment), pyroptosis group [stimulated with 1 \u03bcg/mL lipopolysaccharide (LPS) for 12 hours, followed by 10 \u03bcmol/L nigericin (Nig) treatment for 1 hour], and T\u03b24 treatment group (co-incubated with LPS and Nig, then treated with 1 \u03bcg/mL T\u03b24 for 1 hour). An in vitro sepsis-associated encephalopathy model was established by LPS and Nig co-treatment. Viability of BV2 cells was assessed by CCK-8 assay. RT-qPCR was performed to detect mRNA expression of interleukin (IL)-1\u03b2, interferon-induced protein with tetratricopeptide repeats 1 (IFIT1), and interferon-\u03b2 (IFN-\u03b2). IL-1\u03b2 levels in cell supernatants were measured by ELISA. Protein expression of NLRP3, GSDMD-N, cleaved caspase-1, phosphorylated stimulator of interferon genes (p-STING), and phosphorylated interferon regulatory factor 3 (p-IRF3) was analyzed by Western blot. Cell death rate and mitochondrial reactive oxygen species (ROS) levels were detected by flow cytometry using propidium iodide staining and MitoSOX indicator, respectively. Compared with the pyroptosis group, T\u03b24 treatment alleviated morphological damage caused by pyroptosis in BV2 cells. Intracellular mRNA expression of IL-1\u03b2, IFIT1, and IFN-\u03b2; IL-1\u03b2 concentration in supernatant; protein expression of NLRP3, GSDMD-N, cleaved caspase-1, p-STING, and p-IRF3; cell death rate; and mitochondrial ROS levels were significantly decreased (P0.05). T\u03b24 protects BV2 microglial cells against LPS and Nig-induced pyroptosis by inhibiting oxidative stress and inflammatory responses, potentially through regulation of the cGAS-STING signaling pathway. \u76ee\u7684: \u63a2\u7a76\u80f8\u817a\u7d20\u03b24\uff08thymosin beta 4, T\u03b24\uff09\u5bf9BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\u7126\u4ea1\u7684\u4fdd\u62a4\u4f5c\u7528\u53ca\u5206\u5b50\u673a\u5236\u3002\u65b9\u6cd5: \u5c06BV2\u7ec6\u80de\u5206\u4e3a\u5bf9\u7167\u7ec4\uff08\u4e0d\u4f5c\u4efb\u4f55\u5904\u7406\uff09\u3001\u7126\u4ea1\u7ec4[1 \u03bcg/mL\u8102\u591a\u7cd6\uff08lipopolysaccharide, LPS\uff09\u523a\u6fc012 h\u540e\uff0c\u7ed9\u4e8810 \u03bcmol/L\u5c3c\u65e5\u5229\u4e9a\u83cc\u7d20\uff08Nigericin, Nig\uff09\u5904\u74061 h]\u3001T\u03b24\u5904\u7406\u7ec4\uff08\u540c\u6b65\u7ed9\u4e88LPS\u3001Nig\u540e\uff0c1 \u03bcg/mL T\u03b24\u5904\u74061 h\uff09\u3002\u901a\u8fc7LPS\u8054\u5408Nig\u5904\u7406BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\uff0c\u6784\u5efa\u8113\u6bd2\u75c7\u76f8\u5173\u6027\u8111\u75c5\u4f53\u5916\u6a21\u578b\u3002\u91c7\u7528CCK\u20118\u6cd5\u68c0\u6d4bT\u03b24\u5bf9BV2\u7ec6\u80de\u7684\u7ec6\u80de\u6d3b\u529b\uff0c\u53cd\u8f6c\u5f55\u5b9e\u65f6\u8367\u5149\u5b9a\u91cfPCR\u6cd5\u68c0\u6d4b\u767d\u7ec6\u80de\u4ecb\u7d20\uff08interleukin, IL\uff09\u20111\u03b2\u3001\u5e72\u6270\u7d20\u8bf1\u5bfc\u86cb\u767d\u56db\u80bd\u91cd\u590d\u5e8f\u52171\u3001\u03b2\u5e72\u6270\u7d20mRNA\u8868\u8fbe\u6c34\u5e73\uff0c\u9176\u8054\u514d\u75ab\u5438\u9644\u8bd5\u9a8c\u68c0\u6d4b\u7ec6\u80de\u4e0a\u6e05\u6db2\u4e2dIL\u20111\u03b2\u6c34\u5e73\uff0cWestern blot\u6cd5\u68c0\u6d4bNOD\u6837\u53d7\u4f53\u70ed\u86cb\u767d\u7ed3\u6784\u57df\u76f8\u5173\u86cb\u767d3\u3001\u6d88\u76ae\u7d20D N\u7aef\u7247\u6bb5\u3001\u5207\u5272\u578b\u80f1\u5929\u86cb\u767d\u91761\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u57fa\u56e0\u523a\u6fc0\u56e0\u5b50\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u8c03\u8282\u56e0\u5b503\u86cb\u767d\u8868\u8fbe\u6c34\u5e73\uff0c\u6d41\u5f0f\u7ec6\u80de\u672f\u7ed3\u5408\u7898\u5316\u4e19\u5576\u67d3\u8272\u68c0\u6d4b\u7ec6\u80de\u6b7b\u4ea1\u7387\uff0cMitoSOX\u8367\u5149\u6307\u793a\u5242\u68c0\u6d4b\u7ec6\u80de\u7ebf\u7c92\u4f53\u6d3b\u6027\u6c27\u6c34\u5e73\u3002\u7ed3\u679c: \u4e0e\u7126\u4ea1\u6a21\u578b\u7ec4\u6bd4\u8f83\uff0cT\u03b24\u5904\u7406\u7ec4BV2\u7ec6\u80de\u7126\u4ea1\u5f62\u6001\u635f\u4f24\u51cf\u8f7b\uff0c\u7ec6\u80de\u5185IL\u20111\u03b2\u3001\u5e72\u6270\u7d20\u8bf1\u5bfc\u86cb\u767d\u56db\u80bd\u91cd\u590d\u5e8f\u52171\u3001\u03b2\u5e72\u6270\u7d20mRNA\u8868\u8fbe\u4e0e\u7ec6\u80de\u4e0a\u6e05IL\u20111\u03b2\u542b\u91cf\u3001NOD\u6837\u53d7\u4f53\u70ed\u86cb\u767d\u7ed3\u6784\u57df\u76f8\u5173\u86cb\u767d3\u3001\u6d88\u76ae\u7d20D N\u7aef\u7247\u6bb5\u3001\u5207\u5272\u578b\u80f1\u5929\u86cb\u767d\u91761\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u57fa\u56e0\u523a\u6fc0\u56e0\u5b50\u3001\u78f7\u9178\u5316\u5e72\u6270\u7d20\u8c03\u8282\u56e0\u5b503\u86cb\u767d\u8868\u8fbe\u53ca\u7ec6\u80de\u6b7b\u4ea1\u7387\u3001\u7ebf\u7c92\u4f53\u6d3b\u6027\u6c27\u6c34\u5e73\u964d\u4f4e\uff08P0.05\uff09\u3002\u7ed3\u8bba: T\u03b24\u53ef\u6539\u5584LPS+Nig\u8bf1\u5bfc\u7684BV2\u5c0f\u80f6\u8d28\u7ec6\u80de\u7126\u4ea1\u635f\u4f24\uff0c\u6291\u5236\u6c27\u5316\u5e94\u6fc0\u4e0e\u708e\u75c7\u53cd\u5e94\uff0c\u5176\u673a\u5236\u53ef\u80fd\u4e0ecGAS\u2011STING\u4fe1\u53f7\u901a\u8def\u6709\u5173\u3002.",

In this study, we investigated whether fatigue severity in individuals previously infected with SARS-CoV-2 is associated with immune and metabolic alterations in serum and whether these peripheral changes can influence hippocampal cell function in vitro. Serum cytokines, kynurenine pathway, and tryptophan-derived and monoamine-related metabolites were measured in a total of 38 individuals with past COVID-19 infection. Human hippocampal progenitor cells were exposed to 1% patient serum during proliferation and differentiation, with readouts including cytokine release, metabolite production, and markers of neurogenesis (doublecortin, DCX) and astrocytic reactivity (glial fibrillary acidic protein, GFAP; aquaporin-4, AQP4). Results show that fatigue severity correlates with lower serum levels of interleukin-8 (IL-8) and with lower levels of metabolites of the kynurenine pathway and tryptophan-derived and monoamine-related metabolites, including kynurenine (KYN) and quinolinic acid (QUIN), and 5-hydroxyindoleacetic acid (5HIAA). Exposure of hippocampal cells to serum from individuals with higher fatigue was associated with increased endogenous production of interleukin-13 (IL-13) and the kynurenine metabolite anthranilic acid (ANA) in the cell supernatant, as well as with increased neurogenesis (increased DCX expression) and enhanced astrocytic reactivity (increased GFAP expression). Notably, serum IL-8 level was inversely correlated with both cellular outcomes. Likewise, serum 5-HIAA levels were negatively correlated with IL-13 release, with mediation analysis indicating that 5-HIAA significantly mediated the association between fatigue severity and IL-13 production (71% explained). Overall, our results suggest that fatigue after COVID-19 infection is associated with neuroimmune and metabolic changes in hippocampal cells, involving peripheral serotonin metabolism (5-HIAA) and cytokine signalling (IL-13).",

Lysine crotonylation, a recently discovered post-translational modification, regulates various cellular processes; however, its role in STING activation remains unclear. Here, we identified dehydrogenase/reductase (SDR family) member 9 (DHRS9) as a critical metabolic regulator of the STING signaling pathway. DHRS9 deficiency impaired activation of the\u00a0cGAS-STING pathway, suppressed antiviral immunity against HSV-1, and exacerbated viral replication. Mechanistically, DHRS9 converts butyryl-CoA into crotonyl-CoA, thereby enhancing histone crotonylation (H3K14cr and H3K18cr) at the STING promoter to drive its transcription. AAV-mediated DHRS9 delivery significantly enhances antiviral and antitumor immunity, demonstrating its robust therapeutic potential.

Bone marrow-derived macrophages (BMMs) from Lyz2\u0394Mgmt mice produced higher levels of IL6, TNF\u03b1, and IFN\u03b2 following stimulation with the STING agonist DMXAA, accompanied by increased phosphorylation of TBK1 and IRF3. Lyz2\u0394Mgmt BMMs also exhibited increased expression of CD86, CD40, and CD120a (TNFRI), but reduced MHC class II expression. Metabolic flux analysis revealed enhanced mitochondrial oxidative respiration, increased ATP production, and greater maximal respiratory capacity, whereas glycolytic capacity remained unchanged. In addition, DMXAA-stimulated Lyz2\u0394Mgmt BMMs displayed increased \u03b3H2AX levels and reduced activation of the energy sensor AMPK and autophagy. Transcriptomic analysis further identified enrichment of pathways associated with cellular respiration. Collectively, these findings indicate that MGMT deficiency is associated with enhanced STING-induced inflammatory responses, altered cellular metabolism, and increased DNA damage in macrophages.",

Monoclonal antibodies targeting B\u00a0cell antigens CD19 and CD20, the interleukin-6 receptor, or the complement cascade are used as preventive therapies to reduce relapse rates. We conducted a network meta-analysis (NMA) to compare the effect of rituximab on time to first relapse with ravulizumab, eculizumab, inebilizumab, and satralizumab in patients with NMOSD who are aquaporin-4 (AQP4)-IgG-positive. A systematic search was conducted in PubMed, Scopus, CINAHL, EMBASE, Web of Science, the Cochrane Library, and gray literature sources up to October 31, 2024, and updated on November 1, 2025, following PRISMA guidelines. A network meta-analysis of randomized and open-label trials was conducted to compare time to first relapse between rituximab and other monoclonal antibody therapies. From 6337 records, 3825 duplicates were removed; 2512 were screened, 2327 excluded, leaving eight trials. The prior treatment, relapse history, and definitions and adjudication of relapse varied across studies. Rituximab showed higher hazard ratio (HR) point estimates for time to first relapse compared with ravulizumab with or without immunosuppressive therapies (IST) (HR 5.00, 95%\u00a0CI 0.25, 101.01) and eculizumab\u2009\u00b1\u2009IST (HR 1.17, 95%\u00a0CI 0.12, 10.89), but were lower compared with satralizumab\u2009\u00b1\u2009IST (HR 0.29, 95%\u00a0CI 0.04, 2.23). In patients not receiving IST, rituximab showed numerically higher HR compared with ravulizumab (HR 3.33, 95%\u00a0CI 0.13, 83.16) and eculizumab (HR 1.59, 95%\u00a0CI 0.05, 50.17), but lower point estimates compared with inebilizumab (HR 0.31, 95%\u00a0CI 0.04, 2.31) and satralizumab (HR 0.27, 95%\u00a0CI 0.03, 2.21). This NMA showed hazard ratio point estimates favoring eculizumab and ravulizumab over rituximab. However, wide, overlapping confidence intervals and between-study heterogeneity indicate substantial uncertainty. Head-to-head trials or registry-based studies are needed to determine the most effective treatment for AQP4-IgG-positive NMOSD.",

Recent evidence highlights Enhancer of zeste homolog 2 (EZH2) as a pivotal epigenetic regulator that fosters an immunosuppressive tumor microenvironment, thereby driving immunotherapy resistance. We hypothesized that EZH2 pharmacological inhibition could increase immunotherapy susceptibility. This study aimed to investigate the potential of a novel EZH2 inhibitor, XNW5004, to sensitize lung adenocarcinoma (LUAD) to programmed cell death protein 1 (PD-1) blockade. In vitro, colony formation and apoptosis assays assessed direct cytotoxicity of XNW5004 on tumor cells at 0-12 \u00b5M. A co-culture system of tumor cells and peripheral blood mononuclear cells evaluated immune-mediated killing. In vivo, immunodeficient nude mice and immunocompetent C57BL/6 mice were randomly assigned to the control, XNW5004, anti-PD1, and combination groups to assess the tumor suppressive effect. Underlying mechanisms were explored through RNA sequencing alongside comprehensive cellular and molecular assays. In vitro, pre-treating tumor cells with 1.5 \u00b5M XNW5004 enhanced their sensitivity to immune cell attack, resulting in fewer residual cells and increased apoptosis, an effect further potentiated by PD-1 blockade. In vivo, XNW5004 suppressed tumor growth in immunocompetent C57BL/6 mice but showed minimal effect in immunodeficient nude mice. Mechanistically, XNW5004 stimulated chemokine-mediated recruitment of dendritic cells and T cells into tumor sites. Additionally, it upregulated the antigen presentation molecule major histocompatibility complex class I (MHC-I), while simultaneously augmenting the expression of co-signaling molecules programmed death ligand 1(PD-L1) and intercellular adhesion molecule-1 (ICAM-1). These alterations contributed to the augmented cytotoxic activity of both CD8+ T cells and natural killer cells, as evidenced by increased interferon-\u03b3 and granzyme B. The STING-TBK1-NF-\u03baB axis functions as a pivotal regulatory signaling pathway driving these phenotype alterations. The EZH2 inhibitor XNW5004 enhances anti-tumor immunity and synergistically interacts with PD-1 blockade immunotherapy in LUAD, establishing this combinatorial approach as a promising therapeutic strategy.",

Dehydrocostus lactone (DHE), a blood-brain barrier-permeable sesquiterpene lactone with established anti-inflammatory activity, represents a promising but unexplored therapeutic candidate for ALS/FTD. The therapeutic effects of DHE were evaluated in primary mouse and human astrocytes expressing ALS/FTD-associated RNA-binding protein pathology, ALS patient-derived fibroblasts, and primary cortical neurons exposed to astrocyte-conditioned medium. Drosophila models expressing mutant FUS or TDP-43 in glial cells were used to assess locomotor performance and survival. Molecular analyses examined nuclear factor kappa B (NF-\u03baB) signaling, nuclear factor erythroid 2-related factor 2 (NRF2)-dependent antioxidant responses, protein aggregation, mitochondrial function, and inflammatory mediator production. Plasma concentrations of inflammatory cytokines and chemokines were measured in patients with sporadic ALS. DHE exerted neuroprotective effects through a dual mechanism involving suppression of NF-\u03baB-dependent inflammatory signaling and activation of NRF2-mediated antioxidant pathways in astrocytes exhibiting FUS or TDP-43 proteinopathy. DHE attenuated astrocyte-mediated neurotoxicity and improved neuronal mitochondrial function in conditioned-medium assays. In addition, DHE reduced pathological FUS accumulation in FUS P525L-expressing astrocytes and in stress-challenged patient-derived fibroblasts. In Drosophila models, DHE significantly improved locomotor function and extended survival. Translationally, the chemokines CXCL10, CCL3, and CCL19 were elevated in plasma from patients with ALS, were induced by FUS or TDP-43 pathology in astrocytes, and were suppressed by DHE treatment, supporting the clinical relevance of the inflammatory pathways targeted by DHE. DHE mitigates astrocyte-driven neurotoxicity associated with ALS/FTD-related RNA-binding protein pathology by suppressing inflammatory signaling and enhancing antioxidant defense mechanisms. The consistent therapeutic effects observed across mouse and human cellular models, patient-derived samples, and in vivo Drosophila models support further investigation of DHE as a potential therapeutic strategy for ALS/FTD and highlight astrocyte-mediated signaling pathways as actionable targets in neurodegenerative disease.",

Astrocytes actively regulate synaptic plasticity and memory through dynamic volume transients. Our previous research identified several key molecules, including TREK-1, TRPA1, and Best1 ion channels, as well as the gliotransmitter BDNF, as critical components of astrocytic volume transients. However, the precise mechanisms by which these volume transients influence synaptic plasticity and memory remain poorly understood. In this study, we investigate the roles of TREK-1 and TRPA1 in astrocytic volume dynamics and their downstream effects. Our findings, based on intrinsic optical signal imaging, electrophysiology, and behavioral assays, support a model in which neuronal stimulation induces astrocytic swelling, initiated by K+ uptake through TREK-1 channels and regulated by Ca2+ influx via TRPA1 channels. This swelling is closely associated with short- and long-term potentiation (LTP), and exogenous BDNF restores LTP under conditions of calcium sequestration during astrocytic calcium clamping experiments. Disruption of ion channels associated with astrocytic volume transients leads to significant impairments in spatial memory, as demonstrated by deficits in object-place recognition and passive avoidance tasks. Moreover, these channels contribute to the regulation of synaptic plasticity. These findings implicate astrocytic volume transients and BDNF as pivotal modulators of synaptic plasticity and memory, as well as potential therapeutic targets for addressing memory dysfunctions.",

Among stromal cells, fibroblasts are key effectors of tissue remodeling and inflammation, acquiring a senescence-associated secretory phenotype (SASP) that sustains age-related pathology. Here, we delineate a mechanistic framework in which disruption of energy homeostasis drives mitochondrial dysfunction, innate immune activation, and SASP secretion. Mitochondria act as metabolic sentinels that sense energetic stress through altered AMP/ATP and NAD+/NADH ratios, leading to the generation of mitochondrial danger signals-reactive oxygen species (mtROS) and mitochondrial DNA (mtDNA). These signals converge on canonical immune pathways, including the cGAS-STING axis, NLRP3 inflammasome, and NF-\u03baB signaling, thereby converting metabolic distress into persistent pro-inflammatory output. Using periodontal ligament fibroblasts as a disease-relevant model, we highlight how microbial biofilm exposure induces mitochondrial metabolic reprogramming that amplifies fibroblast SASP, promotes osteoclastogenesis, extracellular-matrix degradation, and alveolar bone resorption. At the transcriptional level, regulatory networks involving NF-\u03baB, C/EBP\u03b2, STATs, and the mTOR-AMPK hub integrate mitochondrial signals to sustain inflammatory senescence. We propose that restoring mitochondrial metabolic homeostasis serves as a highly promising strategy to break the self-perpetuating cycle in which energy imbalance triggers SASP activation, which in turn contributes to chronic inflammation. Researchers must first characterize the tissue-specific mitochondrial signatures of SASP. Subsequently, developing precise, lesion-targeted metabolic interventions will open new avenues for mitigating inflammaging and rejuvenating stromal function across ageing tissues.",

However, it has a narrow therapeutic window and exhibits significant inter-individual variability. Previous studies have suggested that under high altitude conditions, VPA absorption increases and its metabolism slows in healthy rats, indicating that environmental factors can substantially alter its pharmacokinetic (PK) behavior. Nevertheless, it remains unclear how high altitude affect VPA metabolism and efficacy under pathological conditions, such as epilepsy. This study aimed to investigate the effects of high altitude on the PK and pharmacodynamics (PD) of VPA in epileptic rats, providing experimental evidence for individualized medication in epilepsy patients rapidly entering high altitude regions. We prepared the epilepsy model by using the lithium chloride-pilocarpine method. Epileptic rats were randomly assigned to the epileptic + VPA (EV) group and the EV + high altitude (EVH) group for the PK and brain distribution study. VPA concentrations were quantified using a validated liquid chromatography-tandem mass spectrometry (LC-MS/MS) method, and PK parameters were calculated. The expression of P-glycoprotein (P-gp) and hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1) in the blood-brain barrier (BBB) was assessed by Western blot. For the PD study, twenty-four epileptic rats were divided into four groups, including epileptic (E) group, E + high altitude (EH) group, EV group and EVH group. PD effects were evaluated by monitoring seizure scores and the number of seizures. Subsequently, oxidative stress and inflammatory cytokines in brain were measured. High altitude significantly alters the PK behavior and PD of VPA. Compared with the EV group, EVH group showed lower plasma concentrations, reduced area under the curve, increased clearance, and shorter mean residence time. Meanwhile, the expression of HIF-1\u03b1 and P-gp in the BBB was significantly up-regulated in the EVH group. PD studies revealed high altitude increased seizure scores and frequency, along with exacerbated oxidative stress and inflammation. High altitude not only exacerbate seizure severity but also significantly alter the PK and PD of VPA in epileptic rats. This study suggests that epilepsy patients rapidly entering high altitude regions may require an appropriate increase in dosage and enhanced PK/PD monitoring during VPA treatment to ensure clinical efficacy.",

In this review, the hierarchical regulation mechanism of this axis is systematically combed: at the upstream level, intestinal short-chain fatty acids (SCFAs), bile acids (BAs), tryptophan derivatives, and other metabolites can activate AMPK/PGC-1\u03b1, FXR/TGR5, and AhR-mediated energy sensing and receptor signaling pathways; On the functional level, bacterial lipopolysaccharide-TLR4 signal and cGAS-STING/NLRP3 inflammasome pathway activated by cytoplasmic mitochondrial DNA (mtDNA) can amplify innate immune response; At the effect level, mitochondrial reactive oxygen species (ROS), mitochondrial dynamics, and PINK1/Parkin-mediated mitophagy are the common key nodes to regulate mitochondrial quality and inflammatory response. Combined with the two-way relationship between the estrobolome and steroid production, the above processes together form a self-reinforcing closed loop of \"metabolic input-immune amplification-oxidative stress/autophagy-endocrine regulation\". Based on this theoretical framework, this paper analyzes the disease-specific correlations among polycystic ovary syndrome, endometriosis, premature ovarian insufficiency, and gynecological malignancies, and puts forward a dual-targeted treatment idea with research value. The intervention plan with microbiota as the core aims to adjust the metabolite spectrum and endotoxin level; Mitochondria-centered interventions focus on restoring cell energy metabolism and apoptosis sensitivity. In addition, this review constructs a hierarchical research framework of \"microbiota-metabolomics-mitochondria\" to clarify the targeted phenotypes in the pathway, and provide guidance for subsequent clinical trial design and long-term monitoring. With the deep integration of multi-omics technology and targeted interventions, the gut microbiota-mitochondria axis is expected to become an important breakthrough in precision medical treatment of gynecological diseases and build a brand-new bridge between basic mechanism research and clinical transformation.",

This review summarizes current knowledge of cGAS-STING signaling in CNS disorders and evaluates its therapeutic potential. Relevant studies on cGAS-STING signaling in CNS disorders were collected from PubMed and Web of Science, with emphasis on disease mechanisms, neuroinflammatory regulation, and pathway-targeted therapeutic strategies. In the CNS, cGAS-STING signaling exhibits marked region-, cell-, and pathology-dependent heterogeneity. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. Pharmacological inhibition of cGAS, cyclic GMP-AMP (cGAMP), or STING, together with emerging delivery strategies, has shown promise in preclinical models. Clinical translation remains limited by incomplete validation of pathway specificity, limited human evidence, restricted brain delivery, and inconsistent efficacy assessment.

BA 9 RNA levels, measured in 81 people with schizophrenia and 70 healthy controls using the Affymetrix Human Exon 1.0\u2009ST Array, were compared using JMP Genomics 9.0. Differences in levels of RNA between diagnosis were accepted at fold changes of 1.0\u2009\u00b1\u2009\u2265 0.2 and p\u2009<\u20090.01.

Levels of 17,304 RNAs were measured in BA 9, with 47 RNA levels being altered (29 higher) in schizophrenia. These changes in RNA levels should affect water homeostasis, regulation of extracellular space volume, potassium buffering, CSF circulation, interstitial fluid resorption, waste clearance, neuroinflammation, osmosensation, cell migration, calcium signalling and transport, gap junctions and membrane transport.

However, ESCC cells frequently suppress this activation, which contributes to the high rates of immunotherapy resistance (70-80%) observed clinically. Thus, identifying intracellular suppressors of this innate immune response remains an unmet critical need. Herein, through multi-omic analyses, we identify the chromatin assembly factor CHAF1A as a suppressor of the tumor-intrinsic innate immune response in ESCC. We found that CHAF1A was overexpressed in ESCC and negatively correlated with type I interferon production and CD8+ T-cell infiltration. Mechanistically, CHAF1A maintained heterochromatin silencing mediated by H3K9me3, thereby repressing endogenous retroviruses (ERVs). This suppression prevented the accumulation of double-stranded RNA (dsRNA) and the subsequent activation of the MAVS-IRF3 signaling pathway. Concurrently, CHAF1A preserved genomic stability, limiting the release of double-stranded DNA (dsDNA) and activation of the cGAS-STING pathway. Loss of CHAF1A potentiated the response to immunotherapy through the coordinated activation of these dual pathways. We then performed a small-molecule compound screen and identified a CHAF1A inhibitor, Baimaside, which enhanced the effect of anti-PD-1 therapy to augment antitumor immunity. Collectively, these data indicate that CHAF1A represents a potential therapeutic target for sensitizing ESCC to immunotherapy and provide a potential combination strategy for reversing immunotherapy resistance.",

However, the underlying mechanisms linking metabolic disorders and immune damage remain unclear. In a TCE-sensitized mouse model, we demonstrated that TCE sensitization inhibited LKB1/AMPK/mTOR signaling pathway (LKB1 overexpression, AICAR, rapamycin) or autophagy (3-MA) in hepatocytes, resulting in defective mitophagy. This mitochondrial dysfunction leads to leakage of mitochondrial DNA (mtDNA) into the cytoplasm, where mtDNA acts as a damage-associated molecular pattern (DAMP) to activate the cGAS-STING pathway, driving the production of proinflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1), and exacerbating liver inflammation. Restoration of LKB1/AMPK signaling or inhibition of mTOR rescued mitophagi, reduced mitochondrial DNA leakage, inhibited cGAS-STING activation, and alleviated liver pathology, while inhibition of autophagy alone recapitulated the TCE-induced phenotype. Taken together, our findings demonstrate that failure of TCE via LKB1/AMPK/mTOR mediated mitophagy destroys hepatocyte homeostasis, leading to mtDNA-driven cGAS-STING activation and immune-mediated liver injury in the pathogenesis of OMDT, thus providing a potential therapeutic target for OMDT-related liver injury.",

Accumulating evidence links glymphatic dysfunction to neurodegeneration, cerebrovascular disease, and sleep-related disorders, motivating the search for clinically deployable imaging biomarkers. Imaging has become central to this effort, spanning tracer-based approaches and non-invasive MRI methods such as phase-contrast magnetic resonance imaging (MRI), functional MRI-derived CSF dynamics, structural MRI markers including MRI-visible perivascular spaces and parenchymal CSF (pCSF) mapping, and diffusion-based indices including diffusion tensor image analysis along the perivascular space (DTI-ALPS). This review aims toprovide a translation-oriented perspective that reframes the current literature by disentangling what each modality actually measures-such as tracer transport, fluid compartment morphology and distribution, pulsatility-related motion, diffusion-sensitive exchange constraints, or vascular-interface perfusion/exchange physiology-from what it is often interpreted to represent (glymphatic clearance), and by proposing a practical roadmap to improve physiological specificity and clinical utility. Importantly, no truly non-invasive MRI technique can currently directly measure glymphatic transport or CSF-ISF exchange in humans, so existing readouts should be treated as surrogate markers with known confounds. We highlight emerging methods sensitive to slow flow and exchange and outline priorities for clinical translation, including harmonized protocols, cross-site reproducibility, mechanistic validation, and outcome-linked validation in prospective studies.",

Central to this function is mitochondrial dynamics-the controlled equilibrium between fission and fusion-which serves as a critical structural and thermodynamic checkpoint for cellular fate and immunological status. A substantial body of evidence indicates that pathological mitochondrial fission, frequently driven by Dynamin-related protein 1 (Drp1), is a hallmark of numerous inflammatory conditions. Mechanistically, fragmented mitochondria release damage-associated molecular patterns (DAMPs) and induce acute ATP suppression, metabolically \"licensing\" NLRP3 activation by collapsing the ATP hydrolysis potential (\u0394GATP). Recent breakthroughs have redefined this axis, distinguishing between physical damage and metabolic triggers, such as pyrimidine imbalance via the YME1L-SLC25A33 axis. Furthermore, the immunogenicity of DAMPs is strictly context-dependent; oxidized or \"fragile\" mtDNA containing ribonucleotides act as hyper-immunogenic ligands for cytosolic sensors like cGAS-STING. Emerging evidence further highlights that endosomal-mitochondrial crosstalk, intercellular mitochondrial transfer, and lipid-driven metabolic rewiring profoundly govern macrophage polarization and tissue homeostasis. Conversely, promoting mitochondrial fusion and robust quality control preserves organellar integrity and attenuates inflammatory cascades. This review critically synthesizes current literature, deconstructing the molecular linkages between organelle structure and metabolic signaling. By exploring the consequences in sepsis, neuroinflammation, osteoarthritis, and cancer, this treatise evaluates the pharmacological potential of modulating mitochondrial dynamics-ranging from direct Drp1 inhibitors and unfractionated heparin to metabolic stabilizers (e.g., GLP-1 receptor agonists), multi-pronged disruptors (e.g., Antimycin A), targeted nanomedicine, and communication-driven mitochondrial transplantation-positioning this axis as a promising frontier for precision pharmacology.",

This study aims to investigate the mechanistic associations among neuroinflammation, glymphatic dysfunction, tau pathology, and cognitive decline in AD spectrum. The study included 355 participants from the Alzheimer's Disease Neuroimaging Initiative (ADNI) and a supportive cohort of 59 individuals from Wuhan Union Hospital (WHUH). Tau pathology was quantified using 18F-AV1451 positron emission tomography (PET). Glymphatic function was estimated through diffusion tensor image analysis along the perivascular space (DTI-ALPS). Neuroinflammation was assessed via plasma glial fibrillary acidic protein (GFAP) in two cohorts and translocator protein (TSPO) PET imaging with 18F-DPA-714 in supportive cohort. Correlation analyses and mediation models were employed to evaluate the directional relationships among tau deposition, inflammation, glymphatic function, and cognition. Higher levels of inflammation were significantly associated with lower DTI-ALPS index (\u03b2 = -0.171, P\u2009=\u20090.046), which in turn was associated with higher tau burden (\u03b2\u2009=\u20090.162, P\u2009=\u20090.010). Path analysis revealed significant indirect associations linking neuroinflammation to cognitive performance through glymphatic dysfunction and tau pathology, with total indirect effects of -\u20090.165 (95% CI, -\u20090.266 to -\u20090.105) in ADNI and -\u20090.143 (95% CI, -\u20090.386 to -\u20090.013) in WHUH.

Here, we developed an on-demand nanoparticle system that harnesses mitochondrial-ER functional interplay by concurrently inducing mtDNA release and ER stress, thereby relieving the STIM1-mediated brake on STING and enabling robust STING-TBK1 assembly and downstream signaling. This strategy markedly increased the phosphorylation levels of STING, TBK1, and IRF3 by 11.50-, 9.70-, and 8.95-fold, respectively, compared with PBS, outperforming the commercial STING agonist MSA-2 by more than 2-fold. In addition, the nanoparticles enabled spatially controlled co-delivery, allowing extracellular release of a PD-1/PD-L1 inhibitor and intracellular release of mtDNA-releasing and ER stress-inducing agents. Consequently, this on-demand nanoparticle system potently enhanced both innate and adaptive antitumor immunity in vivo, significantly increasing CD8+ and CD4+ T cell infiltration while reducing Tregs, ultimately suppressing tumor progression, metastasis, and recurrence in mouse models of breast and colon cancer.

This narrative review explores the gut-lung microbiota axis in RILI, synthesizing evidence from preclinical models, clinical cohorts (N\u00a0=\u00a052-89), and randomized controlled trials (RCTs). Radiotherapy induces gut dysbiosis, barrier breakdown, and metabolite changes [e.g., short-chain fatty acid (SCFA) and desaminotyrosine (DAT) depletion], promoting inflammation and fibrosis via pathways such as Toll-like receptor 4/nuclear factor kappa B (TLR4/NF-\u03baB), TGF-\u03b2/Smad, sphingosine-1-phosphate (S1P)-S1PR, and cGAS-STING in animal studies. Inter-species microbial variations hinder translation, while lung microbiota shifts remain nascent. In non-small cell lung cancer cohorts, lower gut microbiota stability (a marker of dysbiosis) is associated with an increased risk of grade \u22652 RP (multivariable-adjusted models, p < 0.05), with higher baseline Faecalibacterium abundance conferring protection; however, causality remains unproven due to antibiotic confounding. Mechanisms involve lipopolysaccharide (LPS) translocation, interleukin 25 (IL-25)/S1P-driven type 2 innate lymphoid cell (ILC2) migration, regulatory T cell/T helper 17 cell (Treg/Th17) imbalance, and extracellular vesicle (EV) signaling, with biomarkers such as 16S rRNA sequencing and EV-miRNAs (e.g., miR-486-5p). Artificial intelligence models predict RP with 75% accuracy. Phase-specific interventions, such as pre-radiotherapy gut microbiota monitoring, intra-radiotherapy SCFA supplementation, subacute DAT modulation, and RPF-targeted EV therapies, have been explored in preliminary pilot studies [for example, one small study reported approximately 12% FEV1 improvement following fecal microbiota transplantation (FMT)]. Future large-scale, stratified RCTs that properly account for antibiotics, chemotherapy, and immunotherapy are required to establish causality beyond the current largely associative clinical evidence. The integration of immunotherapy and proton therapy in such trials may help clarify gut-lung interactions, including any microbiota-preserving effects of proton therapy; the role of the lung microbiota in fibrosis remains preliminary.",

Coinfection biology is heterogeneous and dynamic, driven by viral diversity including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza A/B, Respiratory Syncytial Virus (RSV), parainfluenza, metapneumovirus, rhinovirus, adenovirus, and bocavirus, and by the underlying TB stage, from latent and subclinical to active and reactivation disease. Innate sensing pathways, such as Toll-like receptors (TLR), retinoic acid-inducible gene I (RIG-I), and cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING), converge during coinfection, reshaping type I interferon (IFN-I), Nuclear Factor kappa-light-chain-enhancer of activated B cells (NF-\u03baB), and AP-1-driven responses and triggering a network of autocrine and paracrine signaling that reprograms macrophages, dendritic cells, and T-cell subsets. This immune rewiring alters granuloma equilibrium through suppressed Th1/IFN-\u03b3 coordination, exaggerated Th17/IL-17-driven neutrophilia, and regulatory T-cell or IL-10-mediated dampening, which together destabilize macrophage activation and tissue architecture. Oxidative stress, mitochondrial dysfunction, and Matrix Metalloproteinases (MMP)-driven matrix remodeling further integrate with these pathways, converting inflammatory signals into epithelial damage, cavitation, and fibrosis. Consequently, disease outcomes depend critically on timing, viral burden, pathogen order, host immune endotype, and TB stage, such that the same virus can either preserve containment or drive progression depending on the local immunological context. Importantly, the effects of respiratory viral coinfection vary across the TB disease continuum, influencing early granuloma formation, latent infection, reactivation risk, and established disease through distinct immunological mechanisms. Host-directed therapies (HDT) targeting interferon, IL-1, TNF, inflammasome, or metabolic checkpoints hold mechanistic promise but exhibit variable clinical translation, underscoring the need for precision approaches that integrate stage- and endotype-specific biomarkers. This narrative review proposes an integrated systems framework that links viral sensing, immune rewiring, granuloma biology, and tissue-remodeling to TB-respiratory virus coinfection, and emphasizes how timing-aware, biomarker-guided strategies can refine diagnosis, clinical management, prognosis, and vaccine design in vulnerable populations.",

This study investigates the differential expression of Parkinson's disease (PD)-related, oxidative stress, and inflammatory genes in the liver and brain of six-week-old male albino Wistar rats (250-300\u00a0g) subchronically exposed to rotenone (ROT, 1.3\u00a0mg/kg/day, 35 days, b.w.), a pesticide commonly used to model PD. Relative expression levels were measured using quantitative real-time PCR (RT-qPCR) and western blot. Genes involved in mitophagy (Parkin (PARK2), p\u2009=\u20090.0039), oxidative stress response (Parkinson's disease protein (DJ-1), p\u2009=\u20090.0209), lysosomal function (Low-density lipoprotein receptor-related protein-1 (LRP1), p\u2009=\u20090.0418; ATPase cation transporting 13a2 (ATP13a2), p\u2009=\u20090.0308), and inflammation (Tumour necrosis factor alpha (TNF-\u03b1), p\u2009=\u20090.0171) were found upregulated in the brain of ROT-induced rats as compared to control rats, and were also significantly higher than in the liver (p\u2009<\u20090.05). In contrast, significantly higher phosphatase and tensin homolog-induced kinase 1 (PINK1) expression was found in the liver as compared to the brain (p\u2009=\u20090.0198). Notably, these inter-organ differences and transcriptional shifts were absent in the controls. Moreover, the liver exhibited distinct molecular responses, including significant downregulation of ATP13a2 and SNCA (Encoding alpha-synuclein) and overexpression of NFe2-like basic leucine zipper transcription factor 2 (NFe2l2), compared to control rats (p\u2009<\u20090.05). Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-\u03baB), and interferon gamma (IFN-\u03b3) showed no significant changes in either tissue (p\u2009>\u20090.05). These findings demonstrate that distinct molecular alterations in the liver and brain following ROT treatment, including differences in the regulation of genes associated with mitophagy, oxidative stress, proteostasis, and inflammation. Our findings demonstrate tissue-specific molecular associations in the liver and brain within the ROT-induced PD model, providing new insights into the pathophysiology of neurodegeneration and identifying potential biomarkers and therapeutic targets for future studies.",

Here, we show that human macrophages rely on autocrine macrophage migration inhibitory factor signaling to suppress p53 during M2-like transition. Disruption of this pathway led to activation of p53 and, unexpectedly, the nuclear receptor NR4A1, inducing a senescence-like state resembling interleukin (IL)-1\u03b2\u207a and IL-4 Induced 1 (IL4I1)\u207a TAM subsets observed across multiple cancers. These TAM-like macrophages exhibited a transcriptional program driven by NR4A1, similar to that induced in IL-1\u03b2\u207a TAMs by the combined action of tumor necrosis factor \u03b1 (TNF) and the cyclooxygenase-2-dependent arachidonic acid (AA) metabolite prostaglandin E2. They also upregulated the AA-selective acyl-CoA synthase ACSL4, which promoted cell survival and restrained IL-1\u03b2 release despite elevated IL1B expression. This effect was mediated through induction of the IL4I1\u207a TAM marker CD38, which drove the production of IL-10. Mechanistically, ACSL4 preserved the homeostatic function of stimulator of interferon genes (STING). Loss of ACSL4 resulted in extensive macrophage death and converted STING from a homeostatic regulator into a driver of IL-1 cytokine release. Finally, we show that the CDK4/6 inhibitor abemaciclib repolarized TAM-like macrophages toward a more inflammatory phenotype through off-target inhibition of ACSL4. Abemaciclib enhanced inflammatory signaling by modulating ectodomain shedding, increasing TNF while reducing the release of its natural antagonist, TNF receptor II. Together, these findings clarify mechanisms underlying scRNA-seq-defined TAM phenotypes, identify ACSL4 as a potential therapeutic target, and reveal how abemaciclib can promote inflammatory responses in cancer patients.",

The effects of high-definition transcranial direct current stimulation (HD-tDCS) on glymphatic transport and recovery after ICH, as well as the underlying mechanisms, are investigated in a collagenase-induced mouse model. HD-tDCS (anodal stimulation, 0.1\u00a0mA, 10\u00a0min daily) significantly enhances cerebrospinal fluid influx, improves interstitial solute clearance, reduces intracerebral tracer retention, and increases drainage to the deep cervical lymph nodes, as assessed by in vivo two-photon imaging, contrast-enhanced MRI, and ex vivo tracer analysis. HD-tDCS also accelerates hematoma and edema resolution, reduces midline shift and diffusion abnormalities, and improves neurological outcomes. Mechanistically, ICH induces astrocytic proinflammatory activation together with impaired perivascular AQP4 polarization, whereas HD-tDCS upregulates peroxisome proliferator-activated receptor gamma (PPAR\u03b3), suppresses proinflammatory astrocyte activation, and restores perivascular AQP4 localization. Astrocyte-specific knockdown or pharmacologic inhibition of PPAR\u03b3 attenuates HD-tDCS-induced AQP4 repolarization, glymphatic recovery, and neurological improvement. These findings indicate that HD-tDCS promotes hematoma and edema resolution after ICH in association with PPAR\u03b3-dependent astrocyte remodeling, AQP4 repolarization, and glymphatic restoration.",

A clinical presentation suggestive of NMOSD can also be associated with myelin oligodendrocyte glycoprotein (MOG) antibodies (MOGAD). NMOSD can be diagnosed in the absence of autoantibodies (double-negative NMOSD [DN-NMOSD]), but this subgroup has been poorly investigated. We conducted a systematic review and meta-analysis to define the clinical spectrum, prognosis, and treatment response in DN-NMOSD vs AQP4-NMOSD/MOGAD. We searched on PubMed, Scopus, Embase, Google Scholar, Cochrane Library, and ClinicalTrials.gov databases of studies on patients fulfilling inclusion criteria. Patient characteristics, outcome measures, and treatment regimens were extracted. We included 41 of 1,027 articles screened and analyzed 671 patients with DN-NMOSD (median age 38.6 years [range IQR: 32.5-42.85]; female-to-male ratio 1.5:1; median follow-up 44.4 months [range 1-600]), 73.6% of which relapsed. In the meta-analysis, mean annualized relapse rate (ARR) was higher, albeit not significantly, in DN-NMOSD (1.08; 95% CI 0.73-1.43) vs AQP4-NMOSD (0.84; 95% CI 0.45-1.23) and MOGAD (0.61; 95% CI 0.39-0.83, p = 0.08). Administration of maintenance immunosuppression in DN-NMOSD led to a significant ARR reduction (pooled rate ratio 0.19, 95% CI 0.07-0.49; p = 0.001), with high heterogeneity (I2 = 90%, p < 0.0001). In meta-regression, no covariates were associated with ARR reduction, including the administration of specific drugs (rituximab, p = 0.288; azathioprine, p = 0.291; mycophenolate, p = 0.918). The pooled mean difference in pre\u2011 and post\u2011maintenance treatment Expanded Disability Status Scale values indicated a significant change in disability in MOGAD (-0.93, 95% CI -1.67 to -0.19, p = 0.02) but not in AQP4-NMOSD (-0.62, 95% CI -1.85 to 0.61, p = 0.27) or DN-NMOSD (-0.52 (95% CI -1.30 to 0.25, p = 0.16). DN-NMOSD is a heterogenous, severe and highly relapsing disease, where attacks lead to irreversible dysfunction. The administration of maintenance immunotherapy reduces the relapse risk and should be considered early to prevent further disability.",

Here, we examined whether other pattern recognition receptors are commonly activated during bacterial infection. TLR-independent interferon (IFN) responses were induced in macrophages in response to diverse bacterial encounters. Of the cytoplasmic receptor families examined, the cyclic dinucleotide (CDN) sensor STING was required for IFN responses to evolutionarily diverse bacteria. Various bacterial CDNs were present in murine tissues; these activated stimulator of interferon genes (STING) after bacteriolysis in phagolysosomes in a manner requiring two CDN transporters. Importantly, bacterial CDNs were increased in colonic biopsies from patients with inflammatory bowel disease. Systemic delivery of dead, CDN-laden bacteria promoted anti-tumor immunity in mice. Detection of diverse CDNs, including pyrimidine-based CDNs, was an evolutionarily conserved feature of STING, with distinct binding modes for purine- and pyrimidine-based CDNs. Thus, a phagocytosis-CDN-STING connection places cytoplasmic sensing as a common outcome of host-bacteria interactions that set the immune tone of a tissue, with implications for host defense.",

A Critical Review of Mechanisms, Brain Exposure, and Evidence Gaps in Alzheimer's and Parkinson's Disease.\nAbstract: Urolithin A(UA) is a gut microbiota-derived metabolite of dietary ellagitannins and ellagic acid, generated by specific gut bacterial species and absent from food in free form. Preclinical evidence indicates that UA restores PINK1/Parkin-mediated mitophagy, attenuates NF-\u03baB, NLRP3 inflammasome and cGAS-STING-driven neuroinflammation, and preserves synaptic and cognitive function across rodent and cell-culture models of Alzheimer's disease, Parkinson's disease, and age-related cognitive decline. However, circulating UA in humans exists predominantly as phase II glucuronide and sulfate conjugates rather than free aglycone, and human clinical evidence to date establishes UA's safety, favorable pharmacokinetics, mitochondrial target engagement, and benefits to muscle strength and physical function in middle-aged and older adults, with no completed trial yet evaluating cognitive or neurodegenerative disease-modifying outcomes. This review critically examines whether UA's neuroprotective mechanisms are pathway-specific and supported by convergent preclinical and human data, while explicitly separating mechanistic plausibility from demonstrated clinical efficacy.UA therefore represents a promising but still investigational neuro-nutraceutical candidate, with a mechanistic foundation strong enough to justify dedicated, CNS-endpoint-focused clinical trials as the next logical step toward establishing its neuroprotective potential in humans.",

Whether Mn overload promotes cellular senescence and the mechanisms involved remain insufficiently defined. Here, we investigated Mn-induced senescence-associated injury using Caenorhabditis elegans and neuron-like PC12 cells. Mn exposure shortened lifespan, impaired locomotor behavior, altered dopaminergic neuronal signals, and increased senescence-associated \u03b2-galactosidase activity in C. elegans. In PC12 cells, Mn induced senescence-associated phenotypes, including reduced viability, \u03b2-galactosidase positivity, telomere attrition, p53/p21 activation, oxidative stress, mitochondrial dysfunction, DNA damage-related alterations, inflammatory responses, and stimulator of interferon genes (STING)-related signaling. Quercetin attenuated Mn-induced oxidative, mitochondrial, inflammatory, and senescence-associated changes, while STING inhibition partially alleviated cell injury and \u03b2-galactosidase positivity. These findings suggest the involvement of STING-related signaling in Mn-induced neurotoxic injury accompanied by senescence-associated changes and suggest that this process may be pharmacologically attenuated.",

Intriguingly, OTM under periodontitis conditions orchestrates a complex inflammatory microenvironment and exacerbates bone resorption. Stimulator of interferon genes (STING) is a key inflammation mediator, but its role in OTM with periodontitis was unclear. We established an OTM model in rats with ligature-induced periodontitis. In vitro, rat periodontal ligament fibroblasts (PDLFs) were subjected to compressive stress and LPS to mimic orthodontic force and periodontitis inflammation. STING was activated with agonists (cGAMP/diABZI) or inhibited with H151 or knockdown. Inflammatory responses and bone resorption were assessed. RNA sequencing and co-IP followed by LC-MS/MS were used to identify downstream signals. STING activation in PDLFs increased IL-1\u03b2 and IL-6 while reducing Runx-2 and osteogenesis. In periodontitis-OTM rats, STING, IL-1\u03b2 and IL-6 were upregulated and Runx-2 downregulated on the compression side, leading to increased alveolar bone loss that was rescued by H151. Under mechanical-inflammatory stress, activated STING triggered ER stress, and a cascade of cellular responses including increased pro-inflammatory mediators, enhanced apoptosis, altered mechano-response, and suppressed osteogenesis. Meanwhile, Annexin A2 (Anxa2) was identified as a novel STING interactor. Anxa2 knockdown mirrored STING inhibition, suppressing ER stress, inflammatory activation, apoptosis and mechano-response. Mechanistically, Anxa2 knockdown markedly reduced P65 phosphorylation and nuclear translocation, suggesting Anxa2 may serve as an intermediary linking STING to NF-\u03baB activation. STING-Anxa2 interaction was notably increased in PDLFs and in compression-side periodontal tissues under mechanical-inflammatory stress. Within an inflammatory milieu, STING activation in PDLFs is associated with ER stress, pro-inflammatory responses, apoptosis, and suppressed osteogenesis that collectively accelerate bone resorption during OTM. We identified Annexin A2 (Anxa2) as a novel STING interactor whose knockdown attenuated these responses and NF-\u03baB activation, suggesting Anxa2 as a functional intermediary in STING-mediated inflammation.",

As a critical signalling hub linking innate and adaptive immunity, stimulator of interferon genes (STING) has recently been implicated in the pathogenesis of various autoimmune diseases and may regulate tissue inflammation and immune homeostasis through modulation of CD4+ T cell responses. In this study, we found that STING expression was significantly increased in lesional skin tissues from patients with BP compared with healthy controls. Transcriptomic analysis further revealed that differentially expressed genes in peripheral blood CD4+ T cells from BP patients were primarily enriched in the JAK-STAT signalling pathway, T cell activation and differentiation, and type I interferon (IFN-I)-related pathways. Pharmacological inhibition of STING markedly attenuated the aberrant activation of these signalling pathways. Moreover, qRT-PCR analysis confirmed that the mRNA levels of STING1, JAK1, and CXCR5 were significantly elevated in BP patients, whereas treatment with the STING inhibitor C176 suppressed the expression of these molecules. Collectively, our findings suggest that STING may contribute to BP immunopathogenesis by regulating the JAK-STAT signalling axis and promoting abnormal CD4+ T cell activation and differentiation, providing new insights into the molecular mechanisms underlying BP and identifying potential therapeutic targets.",

We will also discuss the expanding phenotypic spectrum highlighted by recent case reports and cohort studies, together with the topic of clinical expressivity, including clinical non-penetrance, and possible mechanistic explanations such as monoallelic expression, the STING HAQ haplotype, and innovative approaches to characterise disease variability. Finally, we discuss current targeted therapeutic approaches for these disabling conditions, as well as potential new treatments for the future. Overall, these findings highlight the need to consider these rare diseases across a wide range of clinical phenotypes.

However, selective STING activation and its quantitative comparison across heterogeneous cell populations remain a tremendous challenge. Herein, we engineered a type of selective STING-activating polysaccharide immunomodulators (SSAPIs) with quantitative STING activation efficiency across tumor cell, macrophage, and dendritic cell (DC). Dextran as an immune cell targeting nanocarrier was employed to improve drug delivery to macrophage and DC, and to avoid the impact of macromolecular self-assembly on drug release kinetics. The STING agonist (DMXAA) was conjugated to dextran via defined linkers to control the selectivity of STING activation in different cell populations. In vitro experiments quantitively revealed the enhanced STING activation of the ester linker SSAPI (DESX) in macrophage, while the disulfide linker SSAPI (DSSX) prompted STING activation across tumor cell and immune cell. In B16F10 and CT26 tumor-bearing mice models, DSSX exhibited much superior antitumor efficacy with six out of eight complete tumor remission by inducing broad immune responses across diverse cell populations to reprogram TIME. Collectively, this work highlights the significance of activating the STING signaling pathway across cell populations in solid tumor for cancer immunotherapy.",

While ongoing research is investigating novel anti-inflammatory and immunomodulatory therapies for such conditions, available antirheumatic drugs may serve a similar purpose. One such drug, methotrexate, has been successfully used at high doses since the 1940s as an anticancer agent and, more recently, at lower doses in patients with autoimmune diseases. Although the effects of methotrexate have traditionally been attributed to its antiproliferative activity via folic acid modulation, additional targets have been identified, including AMP-activated protein kinase, Janus kinase/signal transducer and activator of transcription, high mobility group box 1 protein, the gut microbiota, and additional pharmacological effects of adenosine, a key mediator of methotrexate. The beneficial effects of modulating these targets on downstream inflammatory and immune pathways, cellular senescence, and vascular, metabolic, and brain homeostasis have been increasingly investigated in experimental models. Furthermore, studies conducted over the past 20 years suggest an association between low-dose methotrexate and a decreased risk of certain age-related cardiometabolic and neurodegenerative diseases, particularly in patients with autoimmune conditions. The results of these studies support the potential protective role of methotrexate against age-associated cardiometabolic and neurodegenerative diseases through multiple mechanisms, unlike targeted immunomodulatory and anti-inflammatory drugs, thereby providing a robust framework for investigating its repurposing in future intervention studies. SIGNIFICANCE STATEMENT: New treatments are essential to address the burden of age-related diseases. The important roles of dysregulated inflammation, immunity, and redox signaling in these conditions have spurred research into developing new therapies or repurposing existing drugs to target these dysfunctions. The disease-modifying antirheumatic drug methotrexate has shown potential protective effects against cellular senescence and certain age-related cardiometabolic and neurodegenerative diseases. This knowledge will encourage further research into the repurposing of methotrexate for the treatment of these diseases.",

In this study, an L-configured homoproline derivative Z55 was obtained through structural optimization of the natural product resibufogenin (RBG), which exhibited approximately threefold greater cellular inhibitory activity against STING than RBG (IC50\u202f=\u202f0.40\u202f\u00b1\u202f0.04\u202f\u03bcM for Z55 vs. 1.42\u202f\u00b1\u202f0.11\u202f\u03bcM for RBG), and maintained favorable in vitro safety. Surface plasmon resonance (SPR) analysis confirmed high-affinity binding of Z55 to hSTING (KD\u202f=\u202f2.31\u202f\u03bcM), and a cellular thermal shift assay (CETSA) further demonstrated that Z55 directly engages endogenous STING in living cells, with a thermal stabilization of 4.31\u202f\u00b1\u202f0.7\u202f\u00b0C. Mechanistic studies, including DTT stability and SPR reversibility assays, support a non covalent interaction mode, while molecular docking provided structural insight into the binding interface. Mechanistically, Z55 inhibited STING phosphorylation and downstream activation of p-TBK1 and p-IRF3, leading to decreased levels of key inflammatory cytokines (IL-1\u03b2, IL-6, and TNF-\u03b1) in both colon tissue and serum of mice with ulcerative colitis. Importantly, this series of compounds exhibited a marked chiral-toxicity separation, with the L-configuration identified as the optimal pharmacophore for both efficacy and safety.

Current biomaterial-based strategies often fail to simultaneously address oxidative stress and inflammatory signaling in a sustained and synergistic manner. Here, we develop a thermosensitive Pluronic F127-based composite hydrogel co-delivering a tannic acid\u2011cerium nanozyme and the FPR1 antagonist HCH6-1. The hydrogel undergoes sol-gel transition at body temperature, enabling minimally invasive injection and sustained local release in the intervertebral disc. The cerium nanozyme exerts potent ROS-scavenging activity, effectively reducing intracellular ROS levels and upregulating the antioxidant protein TXNRD1. Meanwhile, HCH6-1 specifically antagonizes FPR1, thereby suppressing cGAS-STING pathway activation and suppressing downstream inflammatory cascades. Beyond direct anti-inflammatory effects, this system significantly enhances mitophagy activity in NP cells, facilitating the clearance of dysfunctional mitochondria and restoring autophagic flux. Collectively, in vitro and in vivo evidence confirms that this dual-functional hydrogel attenuates NP cell inflammation and significantly retards the progression of IDD.

Cellular senescence, characterized by permanent cell-cycle arrest, apoptosis resistance and acquisition of the senescence-associated secretory phenotype (SASP), is the cellular hallmark of ageing. Recent evidence indicates that blood-brain barrier (BBB) dysfunction precedes cognitive decline and pathological protein deposition, representing an early event in AD, with the neurovascular unit (NVU) providing the structural and functional basis of the BBB. Mounting evidence shows that the core NVU cells-brain microvascular endothelial cells (BMECs), pericytes and astrocytes-enter senescence under AD-related conditions. SASP factors released by these cells disrupt BBB junction proteins and trans-BBB transport systems, and propagate senescence within the NVU via paracrine signaling. Peripheral inflammatory mediators and immune cells then traverse the compromised BBB, aggravating AD pathology, while accumulating A\u03b2, tau and reactive oxygen species (ROS) reciprocally accelerate NVU senescence, constituting a proposed vicious cycle. At the molecular level, the cGAS-STING pathway concurrently drives senescence maintenance, SASP induction and type I interferon (IFN-I)-mediated downregulation of BBB junction proteins, serving as a key convergence point linking NVU senescence to BBB injury. From the NVU perspective, this review systematically examines how cellular senescence drives BBB dysfunction and AD progression, clarifies the role of cGAS-STING as a molecular node, and discusses therapeutic strategies targeting NVU senescence to preserve BBB integrity, aiming to offer new insights into AD mechanisms and treatment.",

Mitochondrial DNA (mtDNA) leakage activates the cGAS-STING pathway, triggering excessive inflammatory responses and hindering osteogenesis. Concurrently, defective mitophagy exacerbates mitochondrial damage, perpetuating a cycle of bone loss. This study investigated the role of the mtDNA-cGAS-STING axis in lipopolysaccharide (LPS)-induced bone marrow mesenchymal stem cells (BMSCs) dysfunction and inflammatory bone loss. We exposed BMSCs to LPS and assessed mitochondrial function, mtDNA release, and cGAS-STING activation using RT-qPCR, Western blotting, and immunofluorescence. We then engineered exosomes to co-deliver siRNA targeting STING and PINK1 mRNA, testing their effects on osteogenesis and mitochondrial homeostasis in vitro and in a mouse model of LPS-induced osteoporosis. LPS exposure resulted in mitochondrial damage, mtDNA leakage, and cGAS-STING activation, impairing osteogenic differentiation and increasing inflammatory cytokine expression. While STING inhibition reduced inflammatory signaling, it did not restore mitochondrial function, whereas PINK1 overexpression improved mitophagy and partially suppressed cGAS-STING activation. Dual regulation through siSTING/PINK1@Exo synergistically reduced mitochondrial ROS, restored membrane potential, promoted osteogenic marker expression, and enhanced mineralization in vitro. Dual-regulated exosomes significantly improved trabecular bone microarchitecture, reduced STING expression, and enhanced RUNX2 and OCN expression compared to single treatments through in vivo model. These results demonstrate that combining mitophagy activation with STING inhibition via engineered exosomes offers a promising therapeutic strategy for inflammatory osteoporosis by addressing both mitochondrial dysfunction and chronic inflammation.",

Among these, DNA sensing through the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) axis has emerged as an important mechanism by which nuclear and mitochondrial stress may promote innate immune activation. In aging and Alzheimer's disease (AD), oxidative stress, impaired DNA repair, and mitochondrial dysfunction can lead to the accumulation of cytosolic DNA and activation of cGAS-STING, contributing to sustained inflammatory signaling, cellular senescence, and synaptic dysfunction. In this review, we synthesize emerging mechanistic and translational insights linking cGAS-STING to genomic instability and neuroinflammation. We highlight the expanding roles of this pathway beyond classical immunity, including its influence on autophagy, cellular senescence, microglial activation, and neurovascular integrity as well as its interactions with key pathological features of age-related neurodegenerative disorders, particularly AD. Finally, we highlight recent advances in pharmacological and genetic modulation of cGAS-STING that support its potential as a therapeutic target for age-related neurodegenerative diseases. By reframing neurodegeneration through the lens of DNA sensing, this review provides an updated perspective on the potential role of cGAS-STING in age-related neurodegenerative diseases.",

Glymphatic dysfunction has been associated with Alzheimer's disease and related tauopathies; however, whether impaired glymphatic transport causally drives tau accumulation and neurodegeneration, and whether its enhancement confers therapeutic benefit, remains unclear. Glymphatic water dynamics in PS19 tau transgenic mice were assessed using JJVCPE, a novel MRI-based approach for evaluating brain water exchange. The effect of pharmacological activation of aquaporin-4 (AQP4) with TGN-073 on glymphatic cerebrospinal fluid influx was examined in wild-type mice using dynamic contrast-enhanced MRI. Tau pathology, neurodegeneration, and cerebrospinal fluid tau levels were analyzed in PS19 mice following chronic TGN-073 treatment. AQP4-deficient PS19 mice were examined to determine target specificity. PS19 mice exhibited significant impairment of glymphatic water exchange at early disease stages, which progressively worsened with ageing. Pharmacological activation of AQP4 with TGN-073 robustly enhanced glymphatic-related tracer influx, reduced tau accumulation, neuronal loss, and gliosis, and was accompanied by increased cerebrospinal fluid tau levels. TGN-073 also restored perivascular AQP4 enrichment without significantly altering overall AQP4 abundance. Importantly, these beneficial effects were abolished in AQP4-deficient PS19 mice, demonstrating that both glymphatic enhancement and suppression of tau pathology and neurodegeneration are AQP4-dependent. Our findings support a mechanistic contribution of impaired glymphatic function to tau accumulation and neuronal vulnerability in tauopathy. Pharmacological activation of AQP4 enhances glymphatic function, restores perivascular AQP4 organization, and ameliorates tau pathology, neurodegeneration, and gliosis. These findings identify AQP4-mediated glymphatic modulation as a disease-relevant and therapeutically tractable pathway for tau-related neurodegenerative disorders.",

In this study, we introduced MS@PMXene-TK, an innovative, mitochondria-targeted nanozyme designed for cartilage repair by addressing these key pathological features. This nanozyme platform uniquely integrated a chondro-inductive peptide (SPPEPS)-loaded, polydopamine (PDA)-modified MXene core (S@PMXene) with a reactive oxygen species (ROS)-responsive thioketal-linked polyethylene glycol (PEG-TK) shell and a mitochondria-targeting peptide (MTP-131), enabling precise and responsive therapeutic intervention at the subcellular level. In vitro and in vivo analyses demonstrated that MS@PMXene-TK effectively scavenged mitochondrial ROS within chondrocytes, acting as a \"cruise missile,\" which led to restoration of mitochondrial membrane potential and promotion of mitophagy. This cascade mitigated mtDNA leakage and subsequent activation of the cGAS/STING pathway, a critical inflammatory driver in OA. Concurrently, sustained release of SPPEPS enhanced chondrogenic marker expression and extracellular matrix synthesis, while alleviating macrophage-mediated inflammatory responses, further modulating the inflammatory microenvironment. In an anterior cruciate ligament transection (ACLT)-induced OA mouse model, intra-articular administration of MS@PMXene-TK significantly improved cartilage protection and subchondral bone integrity. These findings establish the potential of this targeted, multi-modal nanozyme strategy to disrupt intertwined pathologies of oxidative stress and inflammation in OA, offering a promising avenue for OA treatment.",

While cuproptosis has recently been defined as a distinct form of regulated cell death driven by copper-induced mitochondrial proteotoxicity, its non-cell-autonomous roles in remodeling the immune landscape remain poorly understood. This review synthesizes emerging evidence to position cuproptosis not merely as a metabolic collapse, but as a potent driver of immunogenic cell death (ICD). We propose a potential \"metabolic-immune\" signaling axis wherein copper-triggered aggregation of lipoylated TCA cycle enzymes leads to mitochondrial membrane rupture and the subsequent leakage of mitochondrial DNA (mtDNA) into the cytosol. This danger signal is sensed by the cyclic GMP-AMP synthase (cGAS), activating the STING pathway to stimulate type I interferon production. We discuss how this cascade orchestrates a systemic immune response, including the recruitment of cytotoxic CD8\u2009+\u2009T cells and the repolarization of tumor-associated macrophages from a pro-tumor M2 to an anti-tumor M1 phenotype. Furthermore, we highlight the translational potential of copper ionophores and bioengineered nanomedicines as next generation immunomodulators. By integrating copper metabolism with innate immunity, this review provides a strategic roadmap for exploiting mitochondrial stress to reverse immune exclusion and overcome therapy resistance in GBM.",

Identification of the factors affecting the responsiveness to nICT could help further improve treatment efficacy. Here, we performed single-cell analysis on 14 ESCC patients undergoing nICT and revealed tumor microenvironment (TME) features associated with differential treatment responses. Nonnegative matrix factorization (NMF) identified five coordinated cellular programs with distinct response associations. Specifically, the NMF3 program mainly comprising immunosuppressive cell subsets was enriched in the minimal or no pathological tumor regression (TRS3) group, in which regulatory T cells (Tregs) and dendritic cells (DCs) exhibited close correlation. In addition, elevated expression of mitochondrial transcription factor A (TFAM) in DCs was associated with increased Treg infiltration in the TRS3 group. A myeloid-specific Tfam knockout mouse model showed that TFAM deficiency reversed the immunosuppressive TME, inhibited tumor growth, and enhanced response to anti-PD-1 therapy in ESCC. Mechanistically, TFAM deficiency in DCs activated the STING-TBK1-IRF3 pathway, thereby promoting DC maturation to enhance anti-tumor immunity. Overall, this study characterized the TME in residual ESCC after nICT and revealed an association between elevated TFAM expression in DCs and poor responsiveness to nICT. These findings indicate the critical role of TFAM deficiency in DCs in activating anti-tumor immunity, highlighting the potential of targeting TFAM to improve the efficacy of immunotherapy and optimize therapeutic strategies.",

To address these limitations, we developed a polymer-based polyvalent peptide and adjuvant (SPPA) that co-delivers lipid-conjugated tumor-specific peptides with Toll-like receptor 7/8 (3M-052) and a STING (2'3'-cGAMP) agonist. This nanoplatform enables efficient peptide encapsulation, sustained release, and targeted delivery to antigen-presenting cells (APCs), thereby enhancing both innate and adaptive immune responses. We synthesized and characterized a library of lipid-conjugated tumor-associated and neoantigenic peptides. In vitro, SPPA significantly upregulated pro-inflammatory genes and cytokine secretion, confirming robust innate immune activation and demonstrated effective cellular uptake and lymphatic trafficking. In vivo, SPPA alone or in combination with anti-PD-1 antibody (\u03b1PD-1) elicited strong cytotoxic T lymphocyte (CTL) responses and inhibited tumor growth in four aggressive syngeneic mouse models: Triple-negative breast cancer (4T1), HER2+ breast cancer (TUBO), lung carcinoma (LLC1), and renal cell carcinoma (RENCA). The combination therapy led to pronounced tumor growth inhibition, survival benefit, and immune cell infiltration, including elevated CD8+IFN-\u03b3+ T cells and M1 macrophages, and reduced regulatory T cells and MDSCs. Spatial transcriptomics revealed localized transcriptional reprogramming, with downregulation of extracellular matrix genes and activation of inflammatory pathways. Collectively, these findings establish SPPA as a potent and versatile nanovaccine platform capable of inducing durable antitumor immunity, especially when combined with immune checkpoint blockade. This approach offers strong translational potential for personalized immunotherapy across diverse solid tumor types.",

This study aimed to explore the impact of VO disturbance on ischemic brain injury. We superimposed the left internal jugular vein occlusion (LIJVO) onto a rat model of ischemia/reperfusion (I/R). Key pathological indices were assessed and the transcriptomic landscape of the injury using the integrated single-cell and single-nucleus RNA sequencing approach, followed by immunofluorescence validation. Superimposed LIJVO significantly exacerbated neurological deficits and infarction, precipitating malignant brain edema and blood-brain barrier breakdown (P\u2009<\u20090.05). The pathological expansion of pro-inflammatory Endothelial0 and Microglia1 subpopulations were identified. We traced these deteriorations to an endothelial-initiated inflammatory cascade: a specific Endothelial0 emerged to recruit leukocytes and trigger a feed-forward loop with hyper-reactive Microglia1. This crosstalk may drive a cytokine storm and tight junction collapse, ultimately leading to severe perivascular infiltration and accelerated neuronal injury. Collectively, this study elucidates that unfavorable VO functions as a critical aggravator in IS via an endothelial-initiated inflammatory cascade. Targeting upstream endothelial activation represents a promising therapeutic strategy for the IS patients with compromised venous drainage.",

RNT-particularly Y-90 radioembolization-may induce immunogenic cell death, cGAS-STING activation, type I interferon signaling, and stromal remodeling. A pilot clinical study of Y-90 plus dual ICIs demonstrated feasibility and safety but limited efficacy. Evidence from EBRT-ICI CRC studies supports radiation-induced immune priming but is not directly transferable to RNT.Conclusion: RNT-ICI combinations are biologically plausible but not yet clinically validated.

        "42478605": "ID: 42478605\nTitle: Early Hypo-Osmolar Stress Regulates Astrocyte Reactivity After Brain Injury: \"New Insights Into Glial Response to Edema\".\nAbstract: Astrocytes are among the first cellular responders to central nervous system injury, yet the mechanisms governing their earliest responses remain incompletely understood. Here, we investigated astrocyte dynamics during the first hours after focal cortical injury induced by cortical devascularization in rats. We observed a rapid and spatially restricted increase in glial fibrillary acidic protein (GFAP) and aquaporin-4 (AQP4) immunoreactivity surrounding the ischemic core as early as 1.5-3.5\u2009h post-lesion, in association with blood-brain barrier disruption and edema-related changes. Within the injury core, astrocytes displayed differential GFAP detection by monoclonal and polyclonal antibodies, together with the appearance of lower-molecular-weight GFAP fragments both in\u00a0vivo and after oxygen-glucose deprivation in\u00a0vitro, suggesting GFAP cleavage in severely damaged astrocytes. At the chromatin level, astrocytes proximal to the lesion exhibited reduced histone H3 acetylation, particularly histone 3 acetylation at lysine 9 (H3K9ac), a phenomenon recapitulated in cultured astrocytes exposed to hypo-osmolar stress. This reduction was transient, reversible upon recovery, and prevented by histone deacetylase (HDAC) inhibition. Functionally, hypo-osmolar stress conditioned astrocyte responses to subsequent stimuli, attenuating nuclear factor kappa B (NF-\u03baB) activation and complement 3 (C3) induction after lipopolysaccharide exposure while enhancing proliferative capacity during recovery. Together, these findings identify edema-associated osmotic stress as an early regulator of astrocyte epigenetic state and functional plasticity, suggesting that astrocytes exposed to edema are primed to adopt distinct responses that may contribute to tissue repair and scar formation following brain injury.",
        "42480279": "ID: 42480279\nTitle: Aconitine promotes injured peripheral nerve recovery through restraining the activation of inflammasome-mediated cell pyroptosis and pathological inflammation.\nAbstract: Peripheral nerve injury (PNI) represents a common neurological condition with significant social and economic implications. Aconitine, a diterpenoid alkaloid derived from Aconitum species, exhibits potent anti-cancer, anti-viral, anti-inflammatory, analgesic, and immunomodulatory activities against malignancies, rheumatic disorders, arthralgia, and select endocrine pathologies. However, the neuroprotective potential of aconitine in PNI repair remains unclear. Here, we revealed that aconitine treatment at the optimal dose significantly improved SFI values, electrophysiological conduction, axon and myelination regeneration, and cell proliferation and migration. Moreover, aconitine attenuated macrophage polarization towards the M1 phenotype, proinflammatory cytokine secretion, and NLRP3 inflammasome-mediated pyroptosis activation in vivo and in vitro. Mechanistically, RNA sequencing and WB analyses identified the TLR4/MyD88/NF-\u03baB and STING/IRF3 signaling pathways as the potential upstream mediators of anti-inflammatory, anti-inflammasome assembly, and anti-pyroptotic actions of aconitine, which was further verified in vitro experiments. Pharmacological reactivation of either pathway abrogated these therapeutic effects. Thus, aconitine mediates neuroprotection and immunomodulation by polarizing macrophages toward the M2 phenotype and inhibiting NLRP3 inflammasome-driven pyroptosis, mechanisms coordinated through dual blockade of the TLR4/MyD88/NF-\u03baB and STING/IRF3 signaling pathways.",

Although its underlying mechanisms remain incompletely understood, mounting evidence implicates chronic neuroinflammation as a key driver. Sustained microglial and astrocyte activation, blood-brain barrier disruption, and aberrant cytokine signaling contribute to prolonged immune dysregulation within the central nervous system, promoting long-term brain dysfunction. In this expert review, we synthesize emerging insights into how neuroimmune processes impair brain function in PCS. We explore novel mechanistic pathways - including local sleep intrusions, impaired memory reconsolidation, and astrocyte-mediated destabilization of functional networks - that may underlie the syndrome's fluctuating and heterogeneous presentation. We evaluate fluid biomarkers of neuroinflammation, including glial fibrillary acidic protein (GFAP), soluble TREM2, S100\u03b2, and pro-inflammatory cytokines such as interleukin-6 and tumor necrosis factor-\u03b1. In parallel, we highlight converging neuroimaging biomarkers derived from PET and MRI studies. These include increased TSPO-PET binding in limbic and frontal regions, alterations in cerebral blood flow and oxygen metabolism, neurometabolic changes detected via MR spectroscopy (e.g., elevated myo-inositol and choline), and increased free water content on diffusion imaging - each suggestive of glial activation and network-level dysfunction. We propose a multiscale, longitudinal framework that integrates molecular, neuroimaging, and behavioral data to link immune dysregulation with brain network instability and symptom emergence. Such integrative approaches are critical for advancing precision diagnostics and informing the development of targeted, mechanism-based treatments for individuals affected by PCS.",

Current research suggests that the inflammatory response of immune cells activated by STING is a key regulatory molecule in cellular inflammatory damage. However, the specific mechanisms underlying STING-mediated CIRI inflammatory responses remain unclear. This study found that STING expression was specifically elevated in microglia in the damaged side of the hippocampus in CIRI model mice, and this elevation was positively correlated with the severity of CIRI. Our previous research indicated that the dynamic process of mitochondrial fusion and fission is closely associated with CIRI. Building on this, we integrated glycolysis, mitochondrial fission, and the STING inflammatory pathway. Mechanistically, our data suggest that DRP1 K616 is a critical candidate site involved in DRP1 lactylation-associated regulation, which promotes STING pathway activation and contributes to the progression of CIRI. In conclusion, our findings offer substantial evidence that lactate-driven DRP1-mediated mitochondrial fission facilitates the involvement of the STING inflammatory pathway in CIRI. These results suggest that modulating lactate metabolism may serve as a crucial upstream strategy for therapeutic intervention in CIRI.",

This study investigated the radiosensitizing effects of either 7-day 30% caloric restriction (CR) or 24-hour fasting in a murine model bearing CT-26 colorectal tumor and explored the underlying mechanisms. CR and fasting pretreatment enhanced irradiation-induced tumor apoptosis, mitochondrial dysfunction, and cytosolic DNA stress, leading to activation of the cyclic GMP-AMP synthase/stimulator of interferon gene (cGAS-STING) pathway, increased infiltration of tumor killing-associated CD8\u2009+\u2009cytotoxic T lymphocytes, and modulation of macrophage polarization toward an antitumor phenotype. In addition, CR and fasting further suppressed the expression of glycolysis and lipid metabolism related proteins in the tumor microenvironment upon radiation exposure. By contrast, CR and fasting protected normal intestinal tissue from irradiation-induced damage. These findings were validated in vitro using CT-26 and normal small intestinal epithelial cells (IEC-6) cultured under medium with or without glucose. The critical role of the cGAS-STING pathway in enhancing radiosensitivity was confirmed through STING siRNA-mediated knockdown, combined with pharmacological intervention using the STING agonist MSA-2 and inhibitor H-151. In conclusion, our findings indicate that CR and fasting may increase the radiosensitivity of colorectal tumors, while reducing radiation injury to normal intestinal tissue.",

Tertiary lymphoid structures (TLSs) are ectopic lymphoid aggregates whose density, maturation state, and spatial localization correlate with clinical prognosis and ICB response across several malignancies. Radiotherapy (RT) can reshape this immune context in opposing directions. By inducing immunogenic cell death, antigen release, cGAS-STING/type I interferon signaling, vascular remodeling, and lymphocyte recruitment, RT can create conditions that support TLS-associated antitumor immunity in selected settings. Conversely, high-dose or large-volume irradiation, poorly timed nodal exposure, and collateral injury to lymphocytes, tumor-draining lymph nodes, stromal scaffolds, and high endothelial venules can disrupt established TLSs or prevent their maturation. This review summarizes current evidence on the bidirectional relationship between RT and TLS biology, differentiating validated mechanisms from indirect evidence and hypothesis-generating translational concepts. We expound on how dose, fractionation, timing, irradiated volume, nodal management and radiation modality may influence antigen presentation, lymphocyte availability, and local immune architecture. Potential strategies such as lymph-node-aware planning, proton or heavy-ion therapy, FLASH RT, vascular normalization, STING or LT\u03b2R agonism, and ICB combinations are evaluated as investigational approaches rather than established TLS-directed clinical interventions. Future studies should evaluate whether optimized RT regimens can preserve or promote the functional maturation of TLSs, integrating paired tissue biopsies, spatial transcriptomics, advanced imaging, and circulating biomarkers to definitively correlate TLS remodeling with clinical outcomes.",

Although viral oncoproteins such as E6 and E7 generate non-self antigens, many HPV-associated tumors persist under immune pressure and show heterogeneous responses to immune checkpoint blockade. This discrepancy reflects a process in which persistent HPV infection and malignant transformation remodel innate immune sensing, interferon (IFN) signaling, antigen presentation, and the tumor microenvironment. These changes impair dendritic cell activation and cytotoxic immune priming while promoting chronic inflammation, myeloid polarization, T-cell exhaustion, and PD-1/PD-L1-mediated adaptive immune resistance. In this review, we discuss how HPV-associated cancers subvert antiviral innate immunity and how these processes contribute to immune evasion. We further highlight therapeutic strategies aimed at restoring antiviral antitumor immunity, including immune checkpoint blockade, STING agonists, therapeutic HPV vaccines, radiotherapy-based combinations, TGF-\u03b2 pathway inhibition, and biomarker-guided treatment approaches. Understanding the links among viral pathogenesis, innate immune remodeling, and checkpoint evasion may support more rational immunotherapy combinations for HPV-associated malignancies.",

Modifiable lifestyle factors, particularly diet and physical activity, are promising preventive targets. Although the Mediterranean diet and regular exercise individually benefit cognition, their combined effects and underlying mechanisms remain poorly synthesised. The systematic review followed PRISMA-ScR guidelines and involved database searches on PubMed, Embase, Web of Science, Cochrane, and CNKI. Study inclusion criteria were defined using the PICO framework. The Mediterranean diet supplies polyphenols and fatty acids that reduce oxidative stress and inflammation, and support neurotrophic and neuroendocrine functions, thus protecting the brain. Meanwhile, physical activity boosts cerebral blood flow, improving antioxidant delivery and stimulating neurotrophic factors like BDNF, IGF-1, and VEGF to enhance brain plasticity. Together, these approaches act synergistically to balance energy metabolism, lower inflammation, and activate antioxidant defenses, thereby preserving brain homeostasis and boosting cognitive function. Evidence suggests a synergistic effect of the Mediterranean diet and physical activity in preserving cognitive function in older adults. The diet directly supports cognitive health and provides essential nutrients for exercise-induced neuroregeneration. Physical activity, in turn, increases cerebral blood flow, improving nutrient delivery and stimulating neurotransmitter release. This interaction enhances brain plasticity, establishing a virtuous cycle between nutrition, exercise, and cognitive health.",

Cyclic dinucleotide (CDN) agonists have clinically validated the impact of targeting this axis but are limited by poor pharmacokinetics, limited tumor penetration, and delivery challenges. Non-CDN based small-molecule modulators such as MSA-2 and amidobenzimidazole (ABZI) directly modulate cGAS-STING signaling. Beyond direct receptor agonism, coupling with metals offer platforms with complementary strategies to engage and amplify cGAS-STING signaling. Complexes incorporating platinum, ruthenium, iridium, rhodium, gold, copper, manganese, or zinc exploit redox activity, coordination versatility, and photophysical properties to induce nuclear or mitochondrial DNA stress, disrupt organelle homeostasis, and promote immunogenic cell death. By coupling STING activation to ferroptosis, pyroptosis, or cuproptosis, these complexes form the foundation of self-emerging design principles with elaborate mechanistic insights, and translational challenges shaping immune modulation for therapeutics.",

Increasing evidence suggests that reduced clearance of metabolic waste and pathological proteins from the brain also contributes to disease onset and progression. Previous studies have often considered choroid plexus (CP) function, glymphatic exchange, and meningeal lymphatic drainage as separate clearance processes. A continuous framework linking these structures and functions is still lacking. This review integrates recent clinical and experimental evidence and proposes the brain clearance continuum as an interpretative framework. It describes three interlinked functional interfaces: the upstream choroid plexus-cerebrospinal fluid (CP-CSF) inflow interface, the midstream parenchymal perivascular exchange interface, and the downstream meningeal lymphatic outflow interface. Under physiological conditions, these interfaces support CSF movement, parenchymal solute exchange, and the outward removal of metabolic waste. In AD, disrupted CSF homeostasis, impaired perivascular exchange, and obstructed meningeal lymphatic outflow may interact, leading to serial failure of the brain clearance continuum. This process is closely associated with A\u03b2/tau accumulation, vascular dysfunction, neuroinflammation, and cognitive decline. We also summarise potential therapeutic strategies directed at different clearance interfaces, whilst emphasising that most evidence remains preclinical or exploratory. The brain clearance continuum provides a systematic framework for understanding clearance failure in AD. It may also offer a theoretical basis for future mechanistic studies and therapeutic development that are stratified by clearance interface and disease stage.",

This review proposes a shift from an amyloid-centered paradigm to a \"clearance-centered bottleneck\" framework, conceptualizing brain homeostasis as a coupled glymphatic-lymphatic circuit. We identify three critical rate-limiting nodes-entry, transit, and exit-that govern this circuit. These nodes fail through distinct mechanisms: arterial stiffening (entry), aquaporin-4 (AQP4) depolarization (transit), and cerebral amyloid angiopathy with impaired meningeal lymphatic drainage (exit). This multilevel failure creates a self-sustaining \"neuroimmune stalemate\"-a state in which trapped antigens and inflammatory mediators perpetuate glial reactivity that further degrades the very clearance infrastructure needed to resolve it. Distinct from prior reviews of glymphatic dysfunction in isolation, this review contributes four interlinked advances: an integrated glymphatic-lymphatic coupled-circuit framework; a bidirectional immune-clearance crosstalk model; a critical appraisal of imaging endpoints graded by trial-readiness; and a combination therapy roadmap. To overcome the current therapeutic plateau, we advocate for multinode interventions that combine amyloid-targeting therapies with clearance-enhancing agents, supported by a readiness-tiered imaging strategy-standardized proxies such as DTI-ALPS and PVS burden as enrichment/secondary endpoints and dynamic contrast-enhanced MRI for mechanistic proof-of-concept."
