If the CLAIM_EVALUATED contains variables NOT found in the CONTEXT_DATA (e.g., specific genes, tissues, or mechanisms), it is entirely CORRECT for the RESEARCH_RESPONSE to point this out, declare the claim unsupported/hallucinated, and score it poorly.

In this review, we examine the structure and regulation of TDP-43, how these features influence its localization and functional activity, and how their disruption may contribute to disease. Among TDP-43's diverse functions, splicing repression of nonconserved RNA sequences termed cryptic exons has emerged as especially central to human disease. TDP-43 nuclear depletion and cytoplasmic aggregation are well-established pathological features in affected neurons and glia of neurodegenerative diseases, and accumulating evidence suggests that loss of TDP-43-mediated splicing repression occurs presymptomatically in disease. Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction. Here, we synthesize current knowledge of TDP-43 biology and curate datasets from human tissues and experimental models, focusing on cryptic splicing to provide a resource for leveraging cryptic exon biology to better understand, detect, and target TDP-43 dysfunction."

This narrative critical review is explicitly scoped to AD and PD, the only neurodegenerative conditions for which postmortem detection of gingipains in affected brain regions, mechanistic evidence from cellular and animal models, and clinical epidemiological data currently exist in sufficient depth to support an integrated synthesis. Robust meta-analyses confirm that periodontitis is associated with elevated AD/PD risk (OR/HR 1.2-3.5), while gingipains have been detected in a high proportion (>85-90%) of postmortem AD/PD brains, correlating with tau/\u03b1-synuclein pathology, neuroinflammation, and neuronal loss. Mechanistic studies in cellular and animal models demonstrate that gingipains can disrupt blood-brain barrier integrity via tight-junction cleavage, trigger NF-\u03baB/NLRP3-driven glial activation, catalyse amyloid-\u03b2/\u03b1-synuclein seeding, induce tau truncation/hyperphosphorylation, and precipitate mitochondrial oxidative damage, thereby generating self-amplifying neurotoxic cascades. Salivary gingipain activity offers a non-invasive, high-sensitivity biomarker candidate for early risk stratification that may outperform conventional fluid markers in prodromal cohorts. Therapeutically, small-molecule gingipain inhibitors have shown neuroprotective effects in preclinical models (e.g., atuzaginstat/COR388 failed primary endpoints in the Phase 2/3 GAIN trial but demonstrated subgroup benefits in P. gingivalis-positive participants; the next-generation inhibitor LHP588 is advancing in the Phase 2 SPRING trial). Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity. This review provides an integrated, isoform-resolved framework linking gingipain structure-function to neurodegeneration. While associative and mechanistic evidence is compelling, definitive causation in humans and disease-modifying efficacy require further validation through biomarker-guided clinical trials. Precision inhibition of gingipains represents a promising upstream strategy for addressing a potentially modifiable microbial contributor at the oral-brain interface."

"abstract_text": "ID: 42358359\nTitle: Global research trends and hotspots of exosome-mediated drug delivery across the blood-brain barrier: a bibliometric study from 2015 to 2025.\nAbstract: The blood-brain barrier (BBB) is a major obstacle to targeted drug delivery for central nervous system (CNS) diseases. Although liposomes and polymeric nanoparticles have improved brain drug delivery, limitations remain in BBB targeting, long-term biocompatibility, and in vivo clearance. Exosomes are endogenous nanoscale extracellular vesicles with favourable biocompatibility, low immunogenicity, and BBB-crossing potential. Therefore, this bibliometric study summarises the current research status, future research trends, and challenges in the more specific field of exosome-mediated BBB drug delivery. A comprehensive search was conducted across the Web of Science Core Collection (WoSCC), PubMed, and Embase databases for relevant English-language literature on exosome-mediated drug delivery across the blood-brain barrier from 2015 to 2025. WoSCC served as the primary source for bibliometric analysis. PubMed and Embase databases were used for supplementary validation. Software such as VOSviewer, CiteSpace, and R-bibliometrix was employed for literature visualisation analysis. This study included 1,365 relevant articles from the WoSCC database, and the annual publication volume showed a steady upward trend. China and the United States significantly lead in both the number of publications and the number of core contributing institutions in this field. Co-occurrence analysis of keywords showed that research hotspots are mainly focused on exosomes, the blood-brain barrier, drug delivery, and Alzheimer's disease. PubMed and Embase were used as supplementary validation databases, including 1,089 and 1,517 records, respectively. Their annual publication trends, major countries/regions, core journals, and keywords/themes were generally consistent with WoSCC, supporting the macro-level stability of the bibliometric findings. Unlike previous bibliometric analyses that mainly focused on overall trends in CNS exosome research, this study focuses specifically on the direction of exosome-mediated drug delivery across the BBB. The findings show a shift from basic vesicle characterisation toward engineered delivery systems, CNS disease applications, and translational evaluation. Mammalian-derived exosomes remain dominant, while plant-derived vesicles, AI-assisted design, biomimetic hybrid nanovesicles, and gut-brain axis strategies are emerging areas of focus. Future research should prioritise systematic platform comparisons, standardised evaluation, quality control, scalable production, long-term safety, and regulatory pathways."

In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target."

"abstract_text": "ID: 42343570\nTitle: STMN2 protein depletion via translation deficits and stress granules in amyotrophic lateral sclerosis.\nAbstract: STMN2 is an abundant neurospecific protein dysregulated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). We previously reported that cellular stress can lead to STMN2 loss due to TDP-43 nuclear condensation. Here, using human and murine neuronal cell models, multiple pharmacological tools, in situ single-molecule analysis of translation and RNA localisation, and longitudinal analysis of neuronal fitness/survival, we establish TDP-43-independent mechanisms of STMN2 depletion under stress. We find that human STMN2 protein level is extremely labile under acute high-magnitude stress. Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing. We further show that STMN2 protein level is highly sensitive to chronic translation deficits, such as those elicited by prolonged low-grade stress. We find that low pre-stress STMN2 sensitises neuronal cells to stress-induced apoptosis, whereas moderately increased STMN2 is protective under stress. Finally, we demonstrate that STMN2 mRNA is upregulated in non-TDP ALS (ALS-FUS) models, which may compensate for translation/stress granule defects in this disease subtype. Consistent with the compensation hypothesis, STMN2 mRNA is also upregulated in the relatively spared (cortex), but not severely affected (spinal cord), CNS regions in ALS-TDP. In conclusion, our study implicates two common denominators in neurodegeneration - dysregulation of translation and stress granules - in STMN2 depletion, independent of TDP-43 loss of function. It also describes an RNA-based compensatory mechanism in ALS underling the unique vulnerability of neurons with developing TDP-43 pathology."

We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology."

Accumulation of DNA damage is emerging as a novel correlative trait of ALS. We recently showed that formation of TDP-43 and FUS cytoplasmic inclusions (CIs) lead to DNA damage accumulation through dysregulation of the DNA damage response (DDR). However, the multiple molecular mechanisms contributing to DNA damage accumulation in affected motor neurons in ALS have not been fully elucidated. In recent years, chemical inhibition of the serine/threonine kinase CHK1 was shown to lead to accumulation of DNA breaks as well as increased apoptosis, in differentiated cortical neurons. Notably, CHK1 has been involved in DNA double-strand break repair in non-dividing cells, by acting through the histone chaperone ASF1A. In this article, we show that cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A. We observe CHK1 protein downregulation in neuronal cell lines, as well as in patient-derived motor neurons progenitors and in the spinal cord of a FUS-ALS mouse model. Restoration of the nuclear levels of CHK1 and ASF1A via transient overexpression, is sufficient to reduce DNA damage signal accumulation and rescues DDR defects. Importantly, we show that the ubiquitin-proteasome pathway is responsible for CHK1 degradation in cells bearing FUS CI, since its inhibition restores CHK1 and ASF1A protein levels. Our study demonstrates that proteasomal-dependent CHK1 and ASF1A downregulation contributes to accumulation of DNA damage in cells affected by ALS-linked protein aggregates."

Upon nuclear clearance and mislocalisation, TDP-43 enters the periphery; acetylation shapes its conformation, trafficking and immunogenicity. This narrative review synthesises single-cell transcriptomics, proteomic immunoprofiling and clinical inflammatory phenotyping to examine whether site-specific acetylated TDP-43 species may be associated with peripheral inflammatory signatures relevant to ALS immunopathology. By integrating separate datasets on acetylated TDP-43, monocyte phenotypes and cytokine modules, we propose two provisional endotypes characterised by monocyte reprogramming, cytokine modules and Blood-Brain Barrier (BBB) dysfunction-each representing clinically actionable pathways. Framed as a provisional neuroimmune interface, the acetylation state is considered here as a plausible molecular correlate and potential therapeutic entry point: a measurable clue to inform pharmacological targeting and, potentially, a modifiable target via p300CREB-Binding Protein (CBP)-Histone Deacetylase (HDAC) axes or sirtuin activity. Recasting TDP-43 from neuropathological hallmark to immunoactive sentinel supports a shift from descriptive nosology to stratified immunotherapy, in which treatment allocation is informed by acetylation-defined peripheral signatures."

We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology. We discuss the implications of a dynamic equilibrium of folded and unfolded rG4s in health and disease, with particular focus on their emerging roles in neurodegeneration."

Although its treatment strategy has gradually developed from traditional chemotherapy to a multimodal treatment system including novel targeted therapy and immunotherapy, primary drug resistance in particular remains the core clinical problem leading to poor patient prognosis. This clinical dilemma indicates that the traditional genotyping system based on genomics has not been able to fully resolve the molecular heterogeneity of acute myeloid leukemia (AML), and it is urgent to establish a precise stratified model that can dynamically reflect the functional status of tumor cells in the initial stage of treatment. In this study, Raman spectroscopy (RS) combined with machine learning algorithm was used to construct a metabolic prognosis prediction model for AML chemotherapy response. Bone marrow single cell Raman spectroscopy data of newly diagnosed AML patients were collected, and the molecular fingerprint was analyzed by principal component analysis linear discriminant analysis (PCA-LDA) and multivariate curve resolute alternating least square method (MCR-ALS). The results showed that the PCALDA model achieved complete remission or non-remission (CR/NR) classification through 24 principal components (cumulative variance contribution of 90.1%), the accuracy of external validation was 94.8% (sensitivity 97.9%, specificity 92.0%), and the AUC reached 96.27%. Protein, lipid, nucleic acid and mixed components were decomposed by MCR-ALS, and lipid and nucleic acid metabolic pathways were enriched in NR group (P < 0.001). Studies have shown that RS single-cell metabolic fingerprint can decode the metabolic reprogramming features associated with chemotherapy resistance in AML, providing a new marker-free and highly sensitive tool for real-time prognostic stratification and targeted intervention."

Despite marked genetic and pathological heterogeneity, a unifying pathogenic framework remains lacking. We propose that axonal transport impairment represents an early and convergent but genotype-modulated upstream vulnerability in ALS, contributing to distal synaptic failure, bioenergetic stress, protein aggregation, neuroinflammation, and neuronal death. Across many ALS models, including SOD1, TARDBP (TDP-43), FUS, and C9orf72, transport deficits are frequently detectable in presymptomatic stages, often preceding overt motor neuron loss or clinical manifestation, although temporal ordering varies by molecular subtype. Human data from induced pluripotent stem cell-derived motor neurons and neuroimaging in mutation carriers further support early transport dysfunction in both familial and sporadic ALS. We synthesize genetic, cellular, and systems-level evidence demonstrating that diverse ALS-associated mutations converge on intracellular trafficking machinery through distinct but interacting mechanisms, disrupting long-range cargo delivery and clearance in motor neurons. This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation. This model generates testable predictions regarding presymptomatic transport biomarkers and the timing of therapeutic intervention. We discuss implications for biomarker development and therapeutic strategy, proposing restoration of axonal transport as a central component of rational multimodal disease modification in ALS."

Current therapies are primarily symptomatic and have not consistently demonstrated prevention of disease progression. This review introduces Programmable gene modulation networks, a systems-level framework that integrates CRISPR/Cas technologies with nanotechnology-enabled brain delivery for precision intervention in Parkinson's disease. Advanced CRISPR modalities, including CRISPR interference, activation, base editing, prime editing, and epigenetic editing, are evaluated for reversible and targeted modulation of disease-relevant gene networks. Non-viral nanocarrier platforms, such as lipid nanoparticles, polymeric systems, and exosome-mimetic vesicles, are discussed for overcoming blood-brain barrier limitations and improving brain-specific delivery. The review further emphasizes translational challenges, including delivery efficiency, off-target effects, long-term safety, manufacturing scalability, and regulatory considerations. By integrating molecular network biology, programmable gene regulation, and translational decision-making, this review provides a roadmap for developing next-generation disease-modifying therapies for Parkinson's disease."

However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation. This comprehensive review compares various CRISPR-Cas9 delivery vectors, viral, nonviral and physical, with a focus on their efficacy in neurological diseases such as AD. Viral vectors viz., adeno-associated viruses (AAVs) and lentiviruses (LVs) demonstrate high transduction efficiency and BBB permeability. AAVs are preferred for their low immunogenicity, minimal toxicity, high neuronal tropism and episomal persistence, enabling sustained expression without insertional mutagenesis. LVs offer larger genetic payloads but raise concerns about genomic integration and potential oncogenesis, though integration-defective variants mitigate these risks. Nonviral vectors, including peptide and polymer-based nanoparticles, lipid nanoparticles (LNPs) and Inorganic carriers such as gold and silver nanoparticles, are less immunogenic and easier to handle but require further optimisation for in\u00a0vivo BBB crossing and endosomal escape. Physical methods such as electroporation and microinjection are suitable for in\u00a0vitro/ex vivo use, while novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis. These preclinical studies show that these technologies can successfully edit genes and provide therapeutic benefits, including amyloid reduction and cognitive improvement in AD models. Yet off-target effects, immune responses and regulatory hurdles persist. Overall, continuous innovation in delivery vector design and safety profile-targeting strategies is crucial for advancing CRISPR-Cas9 towards clinical therapies for AD-based therapies and related neurological disorders."

While conventional platforms such as liposomes, polymeric nanoparticles, and viral vectors often suffer from immune clearance and poor brain accumulation, engineered exosomes leverage natural cellular transport mechanisms to cross the BBB, protect cargo from degradation, and enable biocompatible interactions with target cells. This review takes a mechanistic and translational look at how exosomes are being engineered for CNS disorders, with a particular focus on glioblastoma. We cover exosome biogenesis through ESCRT-dependent and ESCRT-independent pathways, and how the competition between Rab27-driven secretion and Rab7-driven lysosomal degradation determines how many exosomes a cell releases, which has direct consequences for therapeutic production. We then discuss cargo loading strategies, from genetic approaches where donor cells are engineered to package specific molecules during biogenesis to physical methods like electroporation and sonication applied to isolated vesicles, alongside surface modification techniques for directing exosomes toward specific cell types. In glioblastoma, engineered exosomes have shown real promise for delivering chemotherapeutics across the BBB, targeting glioma stem cells, enabling CRISPR-based gene editing, and functioning as combined treatment and imaging tools. Applications in stroke and neurodegenerative diseases, where engineered exosomes carrying microRNAs and neuroprotective cargo have produced encouraging preclinical results, are also discussed. Scalable manufacturing and consistent targeting remain the hardest unsolved problems, and we outline emerging approaches including bioreactor-based production, programmable cargo loading, and patient-specific exosome design that are beginning to address these gaps. Overall, the progress reviewed here suggests that engineered exosomes are moving from an interesting biological concept toward a practically viable platform for CNS drug delivery."

However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models."

Their applications have rapidly expanded with several tissue targeting formulations in early-phase clinical trials. Beyond small molecular drugs, LNDDSs are increasingly employed for delivery of nucleic acid therapeutics, such as ribonucleic acid (RNA) based vaccines and immunomodulators. Recent advances in nanomaterials have enabled LNDDSs not only to transport therapeutic agents across systemic biological barriers but also to selectively destabilize plasma and organelle membranes, such as endosomes and mitochondria, addressing a wide range of diseases. This review systematically examines design strategies for LNDDSs that traverse key biological barriers focusing on the blood-tumor barrier, blood-brain barrier, and lymphatic transport barriers. We further explore approaches including fusogenic, pH-, redox- and, enzyme-sensitive and externally (ultrasound and thermal) triggered LNDDSs to facilitate internalization and membrane destabilization for specific organelle-targeting.

As biologically derived nanocarriers, exosomes have emerged as viable candidates for crossing physiological barriers and effectively delivering target molecules into the central nervous system. This review aims to summarize what is currently known about exosome biogenesis, cargo sorting, and immunological function in relation to infectious disease. In addition, it provides information on how different pathogens have taken advantage of exosomal pathways to increase their virulence and modulate the immune response, while also suggesting options for the therapeutic engineering of exosomes. It critically evaluates technological advances made in exosome engineering, such as CRISPR/Cas9-based cargo loading, ligand-directed surface modification of exosomes, targeted delivery of nucleic acids, and creation of stimuli-responsive release systems for exosome cargo for their potential application as precision therapies against pathogens that infect the brain.

Because motor output combines fast and slow muscle fibers with distinct kinetics, prolonged slow-fiber activation can broaden burst envelopes and blur within-cycle transitions, limiting temporal precision. Here, we show that agility training improves locomotor timing by selectively compressing the activity of slow motor neurons through enhancing commissural inhibition. In adult zebrafish, training increased locomotor stability and reshaped cycle structure in vivo, shortening the contraction phase while extending relaxation. Ex vivo motor-nerve recordings revealed sharper burst envelopes and reduced temporal dispersion after training, explained by a selective narrowing of slow, but not fast, motor neuron discharge within each cycle. Training enhanced phase-locked commissural inhibition during locomotion, consistent with an inhibitory gate aligned to burst offset. Finally, electrophysiology and single-cell transcriptomics associated this plasticity with increased glycinergic receptor expression in slow motor neurons. Together, our findings identify a circuit and a molecular substrate for training-induced gains in agility and suggest that motor precision can be improved by inhibitory reformatting of slow motor output rather than by uniformly increasing excitation."

In this review, we examine the structure and regulation of TDP-43, how these features influence its localization and functional activity, and how their disruption may contribute to disease. Among TDP-43's diverse functions, splicing repression of nonconserved RNA sequences termed cryptic exons has emerged as especially central to human disease. TDP-43 nuclear depletion and cytoplasmic aggregation are well-established pathological features in affected neurons and glia of neurodegenerative diseases, and accumulating evidence suggests that loss of TDP-43-mediated splicing repression occurs presymptomatically in disease. Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction. Here, we synthesize current knowledge of TDP-43 biology and curate datasets from human tissues and experimental models, focusing on cryptic splicing to provide a resource for leveraging cryptic exon biology to better understand, detect, and target TDP-43 dysfunction."

We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology."

As treatment for CNS disorders is primarily palliative, the underlying causes of disease progression are not addressed through conventional pharmacologic therapies. Gene therapy has the potential to address these root causes of disease progression; however, many of the vectors used in gene therapy (e.g., adeno-associated viruses (AAVs)) have limitations such as immunogenicity, low cargo capacity, and crossing the blood-brain barrier (BBB). These limitations have led to significant progress in the development of non-viral gene delivery systems.

We previously reported that cellular stress can lead to STMN2 loss due to TDP-43 nuclear condensation. Here, using human and murine neuronal cell models, multiple pharmacological tools, in situ single-molecule analysis of translation and RNA localisation, and longitudinal analysis of neuronal fitness/survival, we establish TDP-43-independent mechanisms of STMN2 depletion under stress. We find that human STMN2 protein level is extremely labile under acute high-magnitude stress. Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing. We further show that STMN2 protein level is highly sensitive to chronic translation deficits, such as those elicited by prolonged low-grade stress. We find that low pre-stress STMN2 sensitises neuronal cells to stress-induced apoptosis, whereas moderately increased STMN2 is protective under stress. Finally, we demonstrate that STMN2 mRNA is upregulated in non-TDP ALS (ALS-FUS) models, which may compensate for translation/stress granule defects in this disease subtype. Consistent with the compensation hypothesis, STMN2 mRNA is also upregulated in the relatively spared (cortex), but not severely affected (spinal cord), CNS regions in ALS-TDP. In conclusion, our study implicates two common denominators in neurodegeneration - dysregulation of translation and stress granules - in STMN2 depletion, independent of TDP-43 loss of function. It also describes an RNA-based compensatory mechanism in ALS underling the unique vulnerability of neurons with developing TDP-43 pathology."

In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients.

We have previously demonstrated the role of symmetrical dimethylation (me2s) of a conserved arginine residue (R1810 in human POLR2A) in the C-terminal domain (CTD) of RNA polymerase II (RNAPII), which facilitates the recruitment of the Tudor domain-containing protein SMN to resolve R-loops at transcriptional termination sites. Here, we demonstrate that TDP-43 and FUS contribute to transcription termination through the R1810me2s-SMN pathway. Our data show that TDP-43-and to a lesser extent, FUS-are recruited to chromatin via this pathway, and that disruption of their recruitment leads to defective RNAPII termination. This impairment results in the accumulation of R-loops and elevated DNA damage to gene terminators. Using transcriptome-wide analyses, we further show that TDP-43 RNA-binding sites are highly correlated with regions of R-loop formation. Importantly, we find that the RNA-binding activity of TDP-43 is essential for its role in resolving R-loops and promoting efficient transcription termination. These findings establish a mechanistic link between TDP-43/FUS, R-loop resolution, and transcription termination, providing new insights into how their dysfunction may drive genome instability and contribute to the pathogenesis of ALS and FTD."

This narrative critical review is explicitly scoped to AD and PD, the only neurodegenerative conditions for which postmortem detection of gingipains in affected brain regions, mechanistic evidence from cellular and animal models, and clinical epidemiological data currently exist in sufficient depth to support an integrated synthesis. Robust meta-analyses confirm that periodontitis is associated with elevated AD/PD risk (OR/HR 1.2-3.5), while gingipains have been detected in a high proportion (>85-90%) of postmortem AD/PD brains, correlating with tau/\u03b1-synuclein pathology, neuroinflammation, and neuronal loss. Mechanistic studies in cellular and animal models demonstrate that gingipains can disrupt blood-brain barrier integrity via tight-junction cleavage, trigger NF-\u03baB/NLRP3-driven glial activation, catalyse amyloid-\u03b2/\u03b1-synuclein seeding, induce tau truncation/hyperphosphorylation, and precipitate mitochondrial oxidative damage, thereby generating self-amplifying neurotoxic cascades. Salivary gingipain activity offers a non-invasive, high-sensitivity biomarker candidate for early risk stratification that may outperform conventional fluid markers in prodromal cohorts. Therapeutically, small-molecule gingipain inhibitors have shown neuroprotective effects in preclinical models (e.g., atuzaginstat/COR388 failed primary endpoints in the Phase 2/3 GAIN trial but demonstrated subgroup benefits in P. gingivalis-positive participants; the next-generation inhibitor LHP588 is advancing in the Phase 2 SPRING trial). Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity. This review provides an integrated, isoform-resolved framework linking gingipain structure-function to neurodegeneration. While associative and mechanistic evidence is compelling, definitive causation in humans and disease-modifying efficacy require further validation through biomarker-guided clinical trials. Precision inhibition of gingipains represents a promising upstream strategy for addressing a potentially modifiable microbial contributor at the oral-brain interface."

Exosomes are endogenous nanoscale extracellular vesicles with favourable biocompatibility, low immunogenicity, and BBB-crossing potential. Therefore, this bibliometric study summarises the current research status, future research trends, and challenges in the more specific field of exosome-mediated BBB drug delivery. A comprehensive search was conducted across the Web of Science Core Collection (WoSCC), PubMed, and Embase databases for relevant English-language literature on exosome-mediated drug delivery across the blood-brain barrier from 2015 to 2025. WoSCC served as the primary source for bibliometric analysis. PubMed and Embase databases were used for supplementary validation. Software such as VOSviewer, CiteSpace, and R-bibliometrix was employed for literature visualisation analysis. This study included 1,365 relevant articles from the WoSCC database, and the annual publication volume showed a steady upward trend. China and the United States significantly lead in both the number of publications and the number of core contributing institutions in this field. Co-occurrence analysis of keywords showed that research hotspots are mainly focused on exosomes, the blood-brain barrier, drug delivery, and Alzheimer's disease. PubMed and Embase were used as supplementary validation databases, including 1,089 and 1,517 records, respectively. Their annual publication trends, major countries/regions, core journals, and keywords/themes were generally consistent with WoSCC, supporting the macro-level stability of the bibliometric findings. Unlike previous bibliometric analyses that mainly focused on overall trends in CNS exosome research, this study focuses specifically on the direction of exosome-mediated drug delivery across the BBB. The findings show a shift from basic vesicle characterisation toward engineered delivery systems, CNS disease applications, and translational evaluation. Mammalian-derived exosomes remain dominant, while plant-derived vesicles, AI-assisted design, biomimetic hybrid nanovesicles, and gut-brain axis strategies are emerging areas of focus. Future research should prioritise systematic platform comparisons, standardised evaluation, quality control, scalable production, long-term safety, and regulatory pathways."

Because motor output combines fast and slow muscle fibers with distinct kinetics, prolonged slow-fiber activation can broaden burst envelopes and blur within-cycle transitions, limiting temporal precision. Here, we show that agility training improves locomotor timing by selectively compressing the activity of slow motor neurons through enhancing commissural inhibition. In adult zebrafish, training increased locomotor stability and reshaped cycle structure in vivo, shortening the contraction phase while extending relaxation. Ex vivo motor-nerve recordings revealed sharper burst envelopes and reduced temporal dispersion after training, explained by a selective narrowing of slow, but not fast, motor neuron discharge within each cycle. Training enhanced phase-locked commissural inhibition during locomotion, consistent with an inhibitory gate aligned to burst offset. Finally, electrophysiology and single-cell transcriptomics associated this plasticity with increased glycinergic receptor expression in slow motor neurons. Together, our findings identify a circuit and a molecular substrate for training-induced gains in agility and suggest that motor precision can be improved by inhibitory reformatting of slow motor output rather than by uniformly increasing excitation."

Accumulation of DNA damage is emerging as a novel correlative trait of ALS. We recently showed that formation of TDP-43 and FUS cytoplasmic inclusions (CIs) lead to DNA damage accumulation through dysregulation of the DNA damage response (DDR). However, the multiple molecular mechanisms contributing to DNA damage accumulation in affected motor neurons in ALS have not been fully elucidated. In recent years, chemical inhibition of the serine/threonine kinase CHK1 was shown to lead to accumulation of DNA breaks as well as increased apoptosis, in differentiated cortical neurons. Notably, CHK1 has been involved in DNA double-strand break repair in non-dividing cells, by acting through the histone chaperone ASF1A. In this article, we show that cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A. We observe CHK1 protein downregulation in neuronal cell lines, as well as in patient-derived motor neurons progenitors and in the spinal cord of a FUS-ALS mouse model. Restoration of the nuclear levels of CHK1 and ASF1A via transient overexpression, is sufficient to reduce DNA damage signal accumulation and rescues DDR defects. Importantly, we show that the ubiquitin-proteasome pathway is responsible for CHK1 degradation in cells bearing FUS CI, since its inhibition restores CHK1 and ASF1A protein levels. Our study demonstrates that proteasomal-dependent CHK1 and ASF1A downregulation contributes to accumulation of DNA damage in cells affected by ALS-linked protein aggregates."

We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology. We discuss the implications of a dynamic equilibrium of folded and unfolded rG4s in health and disease, with particular focus on their emerging roles in neurodegeneration."

Although its treatment strategy has gradually developed from traditional chemotherapy to a multimodal treatment system including novel targeted therapy and immunotherapy, primary drug resistance in particular remains the core clinical problem leading to poor patient prognosis. This clinical dilemma indicates that the traditional genotyping system based on genomics has not been able to fully resolve the molecular heterogeneity of acute myeloid leukemia (AML), and it is urgent to establish a precise stratified model that can dynamically reflect the functional status of tumor cells in the initial stage of treatment. In this study, Raman spectroscopy (RS) combined with machine learning algorithm was used to construct a metabolic prognosis prediction model for AML chemotherapy response. Bone marrow single cell Raman spectroscopy data of newly diagnosed AML patients were collected, and the molecular fingerprint was analyzed by principal component analysis linear discriminant analysis (PCA-LDA) and multivariate curve resolute alternating least square method (MCR-ALS). The results showed that the PCALDA model achieved complete remission or non-remission (CR/NR) classification through 24 principal components (cumulative variance contribution of 90.1%), the accuracy of external validation was 94.8% (sensitivity 97.9%, specificity 92.0%), and the AUC reached 96.27%. Protein, lipid, nucleic acid and mixed components were decomposed by MCR-ALS, and lipid and nucleic acid metabolic pathways were enriched in NR group (P < 0.001). Studies have shown that RS single-cell metabolic fingerprint can decode the metabolic reprogramming features associated with chemotherapy resistance in AML, providing a new marker-free and highly sensitive tool for real-time prognostic stratification and targeted intervention."

Despite marked genetic and pathological heterogeneity, a unifying pathogenic framework remains lacking. We propose that axonal transport impairment represents an early and convergent but genotype-modulated upstream vulnerability in ALS, contributing to distal synaptic failure, bioenergetic stress, protein aggregation, neuroinflammation, and neuronal death. Across many ALS models, including SOD1, TARDBP (TDP-43), FUS, and C9orf72, transport deficits are frequently detectable in presymptomatic stages, often preceding overt motor neuron loss or clinical manifestation, although temporal ordering varies by molecular subtype. Human data from induced pluripotent stem cell-derived motor neurons and neuroimaging in mutation carriers further support early transport dysfunction in both familial and sporadic ALS. We synthesize genetic, cellular, and systems-level evidence demonstrating that diverse ALS-associated mutations converge on intracellular trafficking machinery through distinct but interacting mechanisms, disrupting long-range cargo delivery and clearance in motor neurons. This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation. This model generates testable predictions regarding presymptomatic transport biomarkers and the timing of therapeutic intervention. We discuss implications for biomarker development and therapeutic strategy, proposing restoration of axonal transport as a central component of rational multimodal disease modification in ALS."

To address these challenges, we developed folic acid-targeted PLGA-zein hybrid core-shell nanoparticles for the codelivery of the alkylating agent TMZ and the natural PARP inhibitor Ellagic acid (FA-TMZ/EA-PZ-CS NPs), thereby enabling simultaneous enhancement of drug delivery and suppression of chemoresistance pathways. Methods and Results: The dual-drug nanoplatform was fabricated using a double-emulsion solvent evaporation method and functionalized via EDC/NHS-mediated folic acid conjugation to promote receptor-mediated uptake. Physicochemical characterisation confirmed uniform spherical morphology, high colloidal stability, efficient drug encapsulation, and sustained biphasic drug release consistent with a core-shell diffusion mechanism. In LN229 glioblastoma cells, folic acid conjugation significantly enhanced cellular internalisation and cytotoxic efficacy compared to free drugs and non-targeted nanoparticles. Combination index analysis revealed strong synergism between TMZ and ellagic acid, resulting in markedly reduced IC50 values. Mechanistic studies demonstrated apoptosis induction, increased DNA damage, inhibition of cell migration at sub-cytotoxic concentrations, and downregulation of PARP gene expression. Conclusion: Overall, this study establishes a targeted core-shell nanotherapeutic strategy that integrates chemotherapy with DNA repair inhibition to overcome TMZ resistance, offering a mechanistically sound strategy that serves as a foundational framework for future translational research."

Notably, these organoids displayed functional neuronal properties, including spontaneous activity, indicative of integrated neural networks.

We previously demonstrated that synapsin-promoted caveolin-1 (SynCav1) preserves cognitive function in the mouse model of AD. This study investigated the therapeutic potential of SynCav1 in a mouse model of TDP-43 proteinopathy. AAV-PhP.eB-SynCav1 was delivered systemically to the TDP-43A315T mouse, followed by cognitive evaluation and biochemical and ultrastructural analysis of brain tissue. SynCav1 exerted robust neuroprotective effects on cognition. Mechanistically, pathological TDP-43 mislocalized to membrane lipid rafts (MLRs), resulting in decreased MLR-associated GluN2A expression and degenerative changes in neuronal ultrastructure. In contrast, SynCav1 delivery alleviated TDP-43 mislocalization on MLRs, stabilized MLR-associated GluN2A expression, and preserved synaptic ultrastructure. Furthermore, SynCav1 mitigated TDP-43-induced mitochondrial hyper-fragmentation and excessive mitochondrial fission signaling. These findings establish a novel link between TDP-43 proteinopathy and MLR instability, supporting SynCav1 as a \"neuron-centric\" candidate for treating TDP-43-related neurodegeneration."

Until recently, only symptomatic management was available. This review provides pediatric neurologists with a comprehensive, practice-oriented overview of emerging disease-modifying therapies for AS, focusing on therapeutic approaches advancing through clinical development. The molecular pathophysiology of AS, natural history considerations critical for trial interpretation, and the current evidence for antisense oligonucleotide (ASO) therapies (ION582, GTX-102/apazunersen, rugonersen), gene replacement approaches (MVX-220), and next-generation strategies including CRISPR-based gene editing, artificial transcription factors, small molecules, and novel delivery platforms are reviewed. ASO therapies targeting the UBE3A antisense transcript represent the most clinically advanced approach, with three candidates showing proof-of-concept efficacy in Phase 1/2 studies and two advancing to pivotal Phase 3 trials. Gene replacement therapy offers potential single-administration treatment but faces challenges regarding safety, immune responses, and durability. Next-generation approaches including CRISPR activation, epigenetic editing, and blood-brain barrier-penetrating delivery systems show preclinical promise. Critical challenges include outcome measurement limitations, genotype stratification, long-term safety monitoring, and ensuring equitable access.

In this review, we examine the structure and regulation of TDP-43, how these features influence its localization and functional activity, and how their disruption may contribute to disease. Among TDP-43's diverse functions, splicing repression of nonconserved RNA sequences termed cryptic exons has emerged as especially central to human disease. TDP-43 nuclear depletion and cytoplasmic aggregation are well-established pathological features in affected neurons and glia of neurodegenerative diseases, and accumulating evidence suggests that loss of TDP-43-mediated splicing repression occurs presymptomatically in disease. Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction. Here, we synthesize current knowledge of TDP-43 biology and curate datasets from human tissues and experimental models, focusing on cryptic splicing to provide a resource for leveraging cryptic exon biology to better understand, detect, and target TDP-43 dysfunction."

This narrative critical review is explicitly scoped to AD and PD, the only neurodegenerative conditions for which postmortem detection of gingipains in affected brain regions, mechanistic evidence from cellular and animal models, and clinical epidemiological data currently exist in sufficient depth to support an integrated synthesis. Robust meta-analyses confirm that periodontitis is associated with elevated AD/PD risk (OR/HR 1.2-3.5), while gingipains have been detected in a high proportion (>85-90%) of postmortem AD/PD brains, correlating with tau/\u03b1-synuclein pathology, neuroinflammation, and neuronal loss. Mechanistic studies in cellular and animal models demonstrate that gingipains can disrupt blood-brain barrier integrity via tight-junction cleavage, trigger NF-\u03baB/NLRP3-driven glial activation, catalyse amyloid-\u03b2/\u03b1-synuclein seeding, induce tau truncation/hyperphosphorylation, and precipitate mitochondrial oxidative damage, thereby generating self-amplifying neurotoxic cascades. Salivary gingipain activity offers a non-invasive, high-sensitivity biomarker candidate for early risk stratification that may outperform conventional fluid markers in prodromal cohorts. Therapeutically, small-molecule gingipain inhibitors have shown neuroprotective effects in preclinical models (e.g., atuzaginstat/COR388 failed primary endpoints in the Phase 2/3 GAIN trial but demonstrated subgroup benefits in P. gingivalis-positive participants; the next-generation inhibitor LHP588 is advancing in the Phase 2 SPRING trial). Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity. This review provides an integrated, isoform-resolved framework linking gingipain structure-function to neurodegeneration. While associative and mechanistic evidence is compelling, definitive causation in humans and disease-modifying efficacy require further validation through biomarker-guided clinical trials. Precision inhibition of gingipains represents a promising upstream strategy for addressing a potentially modifiable microbial contributor at the oral-brain interface."

As treatment for CNS disorders is primarily palliative, the underlying causes of disease progression are not addressed through conventional pharmacologic therapies. Gene therapy has the potential to address these root causes of disease progression; however, many of the vectors used in gene therapy (e.g., adeno-associated viruses (AAVs)) have limitations such as immunogenicity, low cargo capacity, and crossing the blood-brain barrier (BBB). These limitations have led to significant progress in the development of non-viral gene delivery systems. Compared with viral vectors, non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration. This review reports recent advancements in the development of non-viral platforms for CNS gene delivery and focuses on lipid-based nanoparticles, polymeric nanoparticles, exosome-based techniques, and new hybrid technologies. Particular emphasis is placed on nanoparticle modification approaches to enhance BBB penetration and enable delivery of genome-editing technologies (CRISPR/Cas systems). The review provides explanations of clinical trials, regulatory considerations, and manufacturing issues that result from the recent developments noted above. It also explores the emerging role of artificial intelligence in supporting carrier design and enhancing delivery efficiency.

We previously reported that cellular stress can lead to STMN2 loss due to TDP-43 nuclear condensation. Here, using human and murine neuronal cell models, multiple pharmacological tools, in situ single-molecule analysis of translation and RNA localisation, and longitudinal analysis of neuronal fitness/survival, we establish TDP-43-independent mechanisms of STMN2 depletion under stress. We find that human STMN2 protein level is extremely labile under acute high-magnitude stress. Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing. We further show that STMN2 protein level is highly sensitive to chronic translation deficits, such as those elicited by prolonged low-grade stress. We find that low pre-stress STMN2 sensitises neuronal cells to stress-induced apoptosis, whereas moderately increased STMN2 is protective under stress. Finally, we demonstrate that STMN2 mRNA is upregulated in non-TDP ALS (ALS-FUS) models, which may compensate for translation/stress granule defects in this disease subtype. Consistent with the compensation hypothesis, STMN2 mRNA is also upregulated in the relatively spared (cortex), but not severely affected (spinal cord), CNS regions in ALS-TDP. In conclusion, our study implicates two common denominators in neurodegeneration - dysregulation of translation and stress granules - in STMN2 depletion, independent of TDP-43 loss of function. It also describes an RNA-based compensatory mechanism in ALS underling the unique vulnerability of neurons with developing TDP-43 pathology."

In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target."

However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models."

We have previously demonstrated the role of symmetrical dimethylation (me2s) of a conserved arginine residue (R1810 in human POLR2A) in the C-terminal domain (CTD) of RNA polymerase II (RNAPII), which facilitates the recruitment of the Tudor domain-containing protein SMN to resolve R-loops at transcriptional termination sites. Here, we demonstrate that TDP-43 and FUS contribute to transcription termination through the R1810me2s-SMN pathway. Our data show that TDP-43-and to a lesser extent, FUS-are recruited to chromatin via this pathway, and that disruption of their recruitment leads to defective RNAPII termination. This impairment results in the accumulation of R-loops and elevated DNA damage to gene terminators. Using transcriptome-wide analyses, we further show that TDP-43 RNA-binding sites are highly correlated with regions of R-loop formation. Importantly, we find that the RNA-binding activity of TDP-43 is essential for its role in resolving R-loops and promoting efficient transcription termination. These findings establish a mechanistic link between TDP-43/FUS, R-loop resolution, and transcription termination, providing new insights into how their dysfunction may drive genome instability and contribute to the pathogenesis of ALS and FTD."

Although neuroinflammation is increasingly recognized as a hallmark of ALS, the precise molecular programs linking immune responses to MN pathology remain poorly defined. Using an integrated approach that combines single-cell and bulk RNA sequencing with spatial proteogenomics, we characterized both shared and distinct immune dynamics in peripheral blood and spinal cord tissues from patients with sporadic ALS and those carrying C9orf72 repeat expansions. Our analysis revealed broad immune remodeling in C9orf72 ALS, ALS subtype-specific and progression-associated differences in monocyte activation and antigen-experienced CD8 effector memory T cells with clonal features consistent with antigen-driven responses. Spatial mapping revealed complement activation and lipid-programmed myeloid states converging at sites of MN loss and TDP-43 pathology. Together, these findings connect peripheral and central immune alterations to ALS heterogeneity and highlight stratified immunomodulation as a potential therapeutic strategy."

We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology."

While conventional platforms such as liposomes, polymeric nanoparticles, and viral vectors often suffer from immune clearance and poor brain accumulation, engineered exosomes leverage natural cellular transport mechanisms to cross the BBB, protect cargo from degradation, and enable biocompatible interactions with target cells. This review takes a mechanistic and translational look at how exosomes are being engineered for CNS disorders, with a particular focus on glioblastoma. We cover exosome biogenesis through ESCRT-dependent and ESCRT-independent pathways, and how the competition between Rab27-driven secretion and Rab7-driven lysosomal degradation determines how many exosomes a cell releases, which has direct consequences for therapeutic production. We then discuss cargo loading strategies, from genetic approaches where donor cells are engineered to package specific molecules during biogenesis to physical methods like electroporation and sonication applied to isolated vesicles, alongside surface modification techniques for directing exosomes toward specific cell types. In glioblastoma, engineered exosomes have shown real promise for delivering chemotherapeutics across the BBB, targeting glioma stem cells, enabling CRISPR-based gene editing, and functioning as combined treatment and imaging tools. Applications in stroke and neurodegenerative diseases, where engineered exosomes carrying microRNAs and neuroprotective cargo have produced encouraging preclinical results, are also discussed. Scalable manufacturing and consistent targeting remain the hardest unsolved problems, and we outline emerging approaches including bioreactor-based production, programmable cargo loading, and patient-specific exosome design that are beginning to address these gaps. Overall, the progress reviewed here suggests that engineered exosomes are moving from an interesting biological concept toward a practically viable platform for CNS drug delivery."

Because motor output combines fast and slow muscle fibers with distinct kinetics, prolonged slow-fiber activation can broaden burst envelopes and blur within-cycle transitions, limiting temporal precision. Here, we show that agility training improves locomotor timing by selectively compressing the activity of slow motor neurons through enhancing commissural inhibition. In adult zebrafish, training increased locomotor stability and reshaped cycle structure in vivo, shortening the contraction phase while extending relaxation. Ex vivo motor-nerve recordings revealed sharper burst envelopes and reduced temporal dispersion after training, explained by a selective narrowing of slow, but not fast, motor neuron discharge within each cycle. Training enhanced phase-locked commissural inhibition during locomotion, consistent with an inhibitory gate aligned to burst offset. Finally, electrophysiology and single-cell transcriptomics associated this plasticity with increased glycinergic receptor expression in slow motor neurons. Together, our findings identify a circuit and a molecular substrate for training-induced gains in agility and suggest that motor precision can be improved by inhibitory reformatting of slow motor output rather than by uniformly increasing excitation."

Accumulation of DNA damage is emerging as a novel correlative trait of ALS. We recently showed that formation of TDP-43 and FUS cytoplasmic inclusions (CIs) lead to DNA damage accumulation through dysregulation of the DNA damage response (DDR). However, the multiple molecular mechanisms contributing to DNA damage accumulation in affected motor neurons in ALS have not been fully elucidated. In recent years, chemical inhibition of the serine/threonine kinase CHK1 was shown to lead to accumulation of DNA breaks as well as increased apoptosis, in differentiated cortical neurons. Notably, CHK1 has been involved in DNA double-strand break repair in non-dividing cells, by acting through the histone chaperone ASF1A. In this article, we show that cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A. We observe CHK1 protein downregulation in neuronal cell lines, as well as in patient-derived motor neurons progenitors and in the spinal cord of a FUS-ALS mouse model. Restoration of the nuclear levels of CHK1 and ASF1A via transient overexpression, is sufficient to reduce DNA damage signal accumulation and rescues DDR defects. Importantly, we show that the ubiquitin-proteasome pathway is responsible for CHK1 degradation in cells bearing FUS CI, since its inhibition restores CHK1 and ASF1A protein levels. Our study demonstrates that proteasomal-dependent CHK1 and ASF1A downregulation contributes to accumulation of DNA damage in cells affected by ALS-linked protein aggregates."

We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology. We discuss the implications of a dynamic equilibrium of folded and unfolded rG4s in health and disease, with particular focus on their emerging roles in neurodegeneration."

Although its treatment strategy has gradually developed from traditional chemotherapy to a multimodal treatment system including novel targeted therapy and immunotherapy, primary drug resistance in particular remains the core clinical problem leading to poor patient prognosis. This clinical dilemma indicates that the traditional genotyping system based on genomics has not been able to fully resolve the molecular heterogeneity of acute myeloid leukemia (AML), and it is urgent to establish a precise stratified model that can dynamically reflect the functional status of tumor cells in the initial stage of treatment. In this study, Raman spectroscopy (RS) combined with machine learning algorithm was used to construct a metabolic prognosis prediction model for AML chemotherapy response. Bone marrow single cell Raman spectroscopy data of newly diagnosed AML patients were collected, and the molecular fingerprint was analyzed by principal component analysis linear discriminant analysis (PCA-LDA) and multivariate curve resolute alternating least square method (MCR-ALS). The results showed that the PCALDA model achieved complete remission or non-remission (CR/NR) classification through 24 principal components (cumulative variance contribution of 90.1%), the accuracy of external validation was 94.8% (sensitivity 97.9%, specificity 92.0%), and the AUC reached 96.27%. Protein, lipid, nucleic acid and mixed components were decomposed by MCR-ALS, and lipid and nucleic acid metabolic pathways were enriched in NR group (P < 0.001). Studies have shown that RS single-cell metabolic fingerprint can decode the metabolic reprogramming features associated with chemotherapy resistance in AML, providing a new marker-free and highly sensitive tool for real-time prognostic stratification and targeted intervention."

To address these challenges, we developed folic acid-targeted PLGA-zein hybrid core-shell nanoparticles for the codelivery of the alkylating agent TMZ and the natural PARP inhibitor Ellagic acid (FA-TMZ/EA-PZ-CS NPs), thereby enabling simultaneous enhancement of drug delivery and suppression of chemoresistance pathways. Methods and Results: The dual-drug nanoplatform was fabricated using a double-emulsion solvent evaporation method and functionalized via EDC/NHS-mediated folic acid conjugation to promote receptor-mediated uptake. Physicochemical characterisation confirmed uniform spherical morphology, high colloidal stability, efficient drug encapsulation, and sustained biphasic drug release consistent with a core-shell diffusion mechanism. In LN229 glioblastoma cells, folic acid conjugation significantly enhanced cellular internalisation and cytotoxic efficacy compared to free drugs and non-targeted nanoparticles. Combination index analysis revealed strong synergism between TMZ and ellagic acid, resulting in markedly reduced IC50 values. Mechanistic studies demonstrated apoptosis induction, increased DNA damage, inhibition of cell migration at sub-cytotoxic concentrations, and downregulation of PARP gene expression. Conclusion: Overall, this study establishes a targeted core-shell nanotherapeutic strategy that integrates chemotherapy with DNA repair inhibition to overcome TMZ resistance, offering a mechanistically sound strategy that serves as a foundational framework for future translational research."

Until recently, only symptomatic management was available. This review provides pediatric neurologists with a comprehensive, practice-oriented overview of emerging disease-modifying therapies for AS, focusing on therapeutic approaches advancing through clinical development. The molecular pathophysiology of AS, natural history considerations critical for trial interpretation, and the current evidence for antisense oligonucleotide (ASO) therapies (ION582, GTX-102/apazunersen, rugonersen), gene replacement approaches (MVX-220), and next-generation strategies including CRISPR-based gene editing, artificial transcription factors, small molecules, and novel delivery platforms are reviewed. ASO therapies targeting the UBE3A antisense transcript represent the most clinically advanced approach, with three candidates showing proof-of-concept efficacy in Phase 1/2 studies and two advancing to pivotal Phase 3 trials. Gene replacement therapy offers potential single-administration treatment but faces challenges regarding safety, immune responses, and durability. Next-generation approaches including CRISPR activation, epigenetic editing, and blood-brain barrier-penetrating delivery systems show preclinical promise. Critical challenges include outcome measurement limitations, genotype stratification, long-term safety monitoring, and ensuring equitable access.

Tight junction-associated protein 1 (Tjap1), also termed protein incorporated later into tight junctions (Pilt), has been localized to tight junctions (TJs) in epithelial cells and to the trans-Golgi network in fibroblasts; however, its expression, subcellular localization, and functional significance in BMECs are still unknown. Methods: We characterized Tjap1 subcellular localization in mouse and human BMEC cell lines as well as primary mouse BMECs by immunofluorescence with and without pharmacological Golgi disruption by treatment with Brefeldin A, Golgicide A or Pitstop 2. CRISPR/Cas9-mediated Tjap1 knockout cells were generated and examined with regard to their Golgi morphology using immunostaining. Tjap1 mRNA localization was examined by RNAscope in situ hybridization. Quantitative real-time PCR and Western blot was performed to assess the expression of BBB-associated efflux transporters, solute carrier transporters, and cellular receptors in control and Tjap1 knockout cells. Results: Tjap1 predominantly localized to the cis-Golgi compartment, co-localizing with Gm130 rather than Tgn38, and was absent from TJs in BMECs. Tjap1 knockout induced pronounced Golgi fragmentation BMECs. Importantly, Tjap1 knockout significantly downregulated mRNA-expression of Abcb1a, Abcb1b, Abcc4, Slc2a1, Slc7a1, Slc7a5 and Tfrc, while Abcg2 was upregulated. At the protein level, a decrease in the protein levels of Abcb1, Abcc4, Slc2a1, Slc7a1, and Tfrc was observed in Tjap1 knockout cEND cells. Conclusions: In BMECs, Tjap1 is a cis-Golgi-associated protein required for the structural integrity of the Golgi apparatus. Its deletion is associated with Golgi fragmentation and significant alterations in the mRNA and protein expression of drug transporters and receptors at the BBB. These findings identify Tjap1 as a candidate regulator of both Golgi architecture and the BBB transporter profile in vitro, with potential implications for modulating drug transport across the BBB."

Accumulating evidence positions RBPs as both modulators and drivers of the molecular hallmarks of ageing, including genomic instability, loss of proteostasis, mitochondrial dysfunction, cellular senescence, and chronic inflammation. This review synthesises peer-reviewed studies on the multifaceted roles of RNA-binding proteins in organismal ageing and age-related diseases. Key themes include the tissue- and age-dependent changes in expression of turnover and translation regulatory RBPs such as HuR (ELAVL1), AUF1 (HNRNPD), TIA-1, and tristetraprolin (ZFP36), which alter the stability of mRNAs encoding cell-cycle regulators, pro-inflammatory cytokines, and stress-response proteins. Systematic downregulation of core splicing factors, including PTBP1 and several heterogeneous nuclear ribonucleoproteins, drives widespread senescence-associated splicing alterations in pathways governing cell division, autophagy, DNA repair, and mitochondrial function, suggesting a causal contribution to the senescent phenotype. Prion-like RBPs such as TDP-43 and FUS exhibit age-dependent mislocalisation, nuclear depletion, and cytoplasmic aggregation, contributing to splicing defects, impaired RNA transport, and neurodegeneration in amyotrophic lateral sclerosis, frontotemporal dementia, and limbic-predominant age-related TDP-43 encephalopathy. Interactions between RBPs and non-coding RNAs, together with disrupted liquid-liquid phase separation dynamics, further exacerbate age-related decline. By integrating mechanistic studies from cellular and animal models with observations in human cohorts, this review underscores RBPs as central nodes linking multiple ageing hallmarks and highlights their potential as biomarkers and therapeutic targets to promote healthy ageing. Limitations of current models and priorities for future translational research are discussed."

A major feature of TDP-43 pathology is its nuclear depletion, leading to the aberrant inclusion of cryptic exons during RNA splicing. STMN2 and UNC13A have emerged as prominent TDP-43 splicing targets, but the broader impact of TDP-43-dependent cryptic splicing on neuronal function remains unclear. Here, we report previously unidentified TDP-43 splicing targets critical for membrane excitability and synaptic function, including KALRN, RAP1GAP, SYT7, and KCNQ2. Using human stem cell-derived neurons, we showed that TDP-43 reduction induces cryptic splicing and down-regulation of these genes, resulting in impaired excitability and synaptic transmission. In postmortem brains from patients with FTD, these cryptic splicing events occurred selectively in neurons with TDP-43 pathology. Suppressing individual cryptic splicing events using antisense oligonucleotides partially restored neuronal function, and combined targeting almost fully rescued the synaptic deficit caused by TDP-43 loss. Together, our findings provide evidence that cryptic splicing in these synaptic and membrane excitability genes is not only a downstream marker but instead a direct driver of neuronal dysfunction, establishing a mechanistic link between TDP-43 pathology and neurodegeneration in ALS and FTD."

While both loss- and gain-of-function mechanisms contribute to disease, the discovery of cryptic splicing has shed light on the downstream consequences of TDP-43 nuclear clearance for neuronal health. Here, we highlight how loss of nuclear TDP-43 can drive a cascade of events that lead to the impairment of cellular proteostasis and result in a positive feedback loop that perpetuates neuronal dysfunction. This sustains the appearance of cryptic splicing events in genes that are involved in key pathways for the maintenance of axonal homeostasis and synaptic transmission. In contrast to their detrimental effects on neuronal health, cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies."

Although classically defined as a brain-restricted disorder marked by striatal and cortical degeneration, increasing evidence suggests HD as a multisystem disease involving both central and peripheral pathological alterations. This review aims to provide an integrated overview of neuronal and non-neuronal mechanisms underlying HD, focusing on systemic alterations that influence disease onset, progression, and clinical variability. This review also aims to connect neuropharmacology with pharmaceutical formulation strategies, particularly emphasizing the therapeutic and drug-delivery challenges and nanotechnology-based solutions. A structured literature review was conducted using databases including PubMed, EMBASE, and Scopus. Using the appropriate keywords, original articles, clinical studies, systematic reviews, meta-analyses, and high-quality reviews were selected based on their relevance to HD pathophysiology and therapeutic strategies. HD manifests with motor, cognitive, and psychiatric disturbances; however, this review highlights that peripheral immune activation, gut microbiota dysbiosis, and multiorgan pathology are not merely secondary features but interact with neural circuits, contributing to disease heterogeneity and progression. Current therapeutic approaches are largely symptomatic, achieving minimal effectiveness in disease modification due to challenges such as poor blood-brain barrier penetration, limited target selectivity, and inter-individual variability. New strategies, such as nanotechnology-based drug delivery systems, biologics, and gene editing tools, offer advantages and support a deeper understanding of therapeutic limitations and disease mechanisms, yet their translational applicability remains constrained by limited clinical validation, safety concerns, and scalability problems. Reconceptualizing HD as a multisystem disorder provides a more comprehensive framework for therapeutic development. Integrating central and peripheral disease mechanisms with advances in targeted drug delivery and patient stratification approaches, such as sex differences, hormonal influences, and environmental factors, is essential for translational progress toward personalized therapeutic approaches. Future research should prioritize interdisciplinary approaches to bridge the gap between mechanistic discoveries and effective disease-modifying interventions."

The existing therapies have only a small effect on alleviating symptoms, mainly because the therapeutic agents are difficult to cross the bloodbrain barrier. The purpose of the review is to discuss the potential of microneedle-based transdermal delivery systems to improve the delivery of drugs to the central nervous system and thereby manage neurodegenerative diseases effectively. The article summarizes and synthesizes the available literature that targets the strategies of microneedle-mediated drug delivery. The literature on the design, composition, pharmacokinetics, and mechanistic benefits of different microneedle platforms for surmounting central nervous system barriers was identified and thematically synthesized. Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier. Micro-needles can be used to deliver small molecules, peptides, and nanoparticles to the brain, thereby avoiding systemic side effects and enhancing drug bioavailability. Some of those designs include dissolving, coated, hollow, hydrogel-forming, and stimuli-responsive microneedles, which have been shown to target the brain and exhibit higher therapeutic efficiency in preclinical models. Although technological advances have improved, the clinical translation of microneedlebased strategies remains limited. The future directions could include using microneedles with stem cell-based therapies, CRISPR/Cas9 gene editing, artificial intelligence-based delivery systems, and responsive release technology to facilitate customized treatment. The Microneedle-based drug delivery systems are promising in overcoming the current limitations in the treatment of neurodegenerative diseases. Nonetheless, a large-scale clinical validation is necessary to guarantee safety, efficacy, and scalability to be applied to real-life scenarios."

To decipher the underlying mechanisms responsible for these contradictions, we leverage emerging technologies that establish comprehensive cellular and spatiotemporal contexts for its signaling pathway. These approaches elucidate the mechanisms underlying central nervous system diseases and their potential therapeutic applications. In this review, we demonstrate how these advanced technologies enhance our understanding of the mechanism of activin A: CRISPR-based editing validates critical receptors such as ACVR1B in the process of remyelination; organoid and organ-on-a-chip systems model human-specific cellular interactions; spatial and single-cell multi-omics delineate expression and communication networks; and optogenetics/chemogenetics enable precise spatiotemporal control of signaling pathway activity. This technological toolkit provides a robust framework for elucidating the context-specific roles of activin A in conditions such as ischemic stroke, neurodegenerative diseases, glioma, epilepsy, and traumatic brain injury, encompassing key processes including neuroprotection, inflammation, and repair. Furthermore, these mechanistic insights inform next-generation interventions, including adeno-associated virus-mediated gene therapy for localized modulation and advanced nanodelivery systems for targeted biologic transport. Given these capabilities, artificial intelligence plays a crucial role in designing blood-brain barrier-permeable ligands and optimizing smart nanocarriers. By contrasting preclinical data with the clinical pipeline, which currently emphasizes peripheral diseases, we propose that integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement."

However, current reviews often catalog virus-disease associations without integrating this evidence into a unified conceptual model that also accounts for the therapeutic potential of viral platforms. This review investigates recent literature to propose a \"dual-role\" model for viruses in NDDs. We analyze how diverse viruses (e.g., HSV-1, HIV, EBV, and SARS-CoV-2) converge on shared pathogenic pathways, including protein misfolding, chronic neuroinflammation, and mitochondrial dysfunction, across different NDDs. Paradoxically, engineered viral vectors derived from neurotropic viruses are being investigated as tools for targeted gene therapy. To address these therapeutic applications of viruses, this review also provides an in-depth report of the various viral vector technologies developed. The approaches involved in designing rationally engineered viral vectors based on various adeno-associated virus serotypes through rational design, directed evolution and machine learning strategies, as well as the lentiviral and herpes simplex virus-based platform are described. Different strategies that have been used to incorporate large and/or small payloads such as gene replacement, RNA interference, microRNA cassettes, CRISPR-based gene editing (base editing, prime editing, CRISPRa and CRISPRi) and the double AAV systems to deliver larger transgene cassette have also been reviewed. This review further includes various routes of administration including intrathecal, intracerebroventricular and convection-enhanced delivery with the use of Focused Ultrasound. The constraints imposed by the Blood-Brain Barrier are discussed, especially the approach using receptor-mediated transcytosis for crossing. The review also critically evaluates obstacles toward clinical translation of viral vectors due to various factors including immunogenicity, the presence of pre-existing neutralising antibodies and dose-dependent toxicity, illustrated by the fatal outcome of ASPIRO and DMD trials. Finally, this review concludes with other promising non-viral approaches such as lipid nanoparticle and extracellular vesicles. Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors."

Dysregulation of RNA metabolism and splicing has emerged as a central mechanism in ALS pathogenesis. TARDBP (TAR DNA-binding protein), FET family proteins (FUS, EWSR1, TAF15), SOD1 (Superoxide Dismutase 1), and C9orf72 (Chromosome 9 Open Reading Frame 72) are key genes associated with ALS that regulate RNA processing, alternative splicing, and nuclear-cytoplasmic transport. Mutations or mislocalization of these proteins result in nuclear loss-of-function and cytoplasmic gain-of-function toxicity, promoting protein aggregation, sequestering spliceosomal components, and impairing spliceosome assembly. This leads to the aberrant inclusion of cryptic exons in essential neuronal genes, such as STMN2 (Stathmin 2) and UNC13A (Unc-13 Homolog A), resulting in the production of truncated proteins, defective axonal maintenance, and impaired synaptic function. TDP-43 pathology, a hallmark of ALS, disrupts splicing and RNA transport, while C9orf72 repeat expansions and FET protein mutations exacerbate cytoplasmic aggregation and stress granule dynamics. Mutant SOD1 contributes via mitochondrial dysfunction, endoplasmic reticulum stress, and disrupted axonal transport. Therapeutic strategies targeting these mechanisms are advancing rapidly. Gene replacement therapy, which restores STMN2 expression, and antisense oligonucleotides (ASOs) targeting mutant transcripts show promise in preclinical and early clinical studies. Complementary approaches, including the inhibition of stress kinases and the activation of autophagy, reduce cytoplasmic protein aggregation and support neuronal homeostasis. This review provides a comprehensive overview of RNA splicing regulation, spliceosomal dysfunction, and cryptic exon incorporation in ALS. Understanding the interplay among splicing defects, RNA-binding protein pathology, and neuronal degeneration is critical for developing next-generation multimodal therapies to restore RNA processing, reduce toxic protein accumulation, and promote motor neuron survival."

A key driver of this pathogenesis is nuclear loss of ALS-associated protein TDP-43, leading to mis-splicing of TDP-43 targets including important neuronal genes STMN2 and UNC13A . Here, we have developed a gene therapy strategy for ALS and related TDP-43 proteinopathies, to correct mis-splicing of both STMN2 and UNC13A cryptic exons using small nuclear RNAs (snRNAs) encoded from a single vector. We identified promoter sequence elements to increase therapeutic snRNA expression by 10-fold, then further optimized the expression cassette with combinatorial snRNA targeting to rescue multiple cryptic splicing targets. The engineered snRNAs restored normal pre-mRNA processing of both STMN2 and UNC13A transcripts despite TDP-43 loss of function, rescuing stathmin-2 protein levels in iPSC derived motor neurons, restoring their axonal regeneration capacity to wild-type levels. In addition, adeno-associated virus (AAV) delivery of the snRNAs to the murine central nervous system in the constitutive cryptic splicing model Stmn2 Hum\u0394GU fully restored cortical Stmn2 pre-mRNA processing, highlighting the utility of snRNAs as a therapeutic modality in vivo . Together, this study demonstrates that snRNAs are a promising and versatile therapeutic strategy for the simultaneous correction of multiple aberrant transcripts affected by cryptic splicing in TDP-43 proteinopathies."

Increasing evidence suggests that long non-coding RNAs (lncRNAs) play significant roles in neurodevelopment, neuronal homeostasis, and disease progression; however, their involvement in shared pathogenic pathways and clinical applications remains inadequately defined. This review consolidates recent experimental, transcriptomic, bioinformatic, and emerging clinical findings regarding the role of lncRNAs in NDDs. We examine how lncRNAs modulate common disease mechanisms, including protein misfolding and aggregation, neuroinflammation, mitochondrial dysfunction, ferroptosis, synaptic failure, and aging-related neurodegenerative processes. These regulatory functions occur through various mechanisms, including epigenetic modifications, transcriptional regulation, post-transcriptional processes, and RNA-protein interactions, as well as novel mechanisms such as liquid-liquid phase separation (LLPS), peptide coding, and exosome-mediated intercellular communication.\u00a0Current evidence supports the potential of lncRNAs as minimally invasive liquid biopsy biomarkers, detectable in blood, cerebrospinal fluid (CSF), and extracellular vesicles. Additionally, lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms. Overall, lncRNAs have emerged as central molecular regulators and promising candidates for translation in NDDs. Nonetheless, challenges related to specificity, validation, delivery across the blood-brain barrier, and clinical standardization must be addressed before their routine application in precision neurology."

To better capture this heterogeneity using single-cell long-read sequencing data, we previously developed an exome-probe-based approach to enrich for exonic reads of target genes. While effective, this procedure is time-consuming and expensive. Real-time targeting offers a more cost-efficient solution for selectively sequencing reads of interest. Here, we performed real-time enrichment of exonic sequences of single-cell long reads by targeting spliced transcripts from 3377 genes implicated in brain functions and related diseases. Our approach increased the total number of spliced on-target reads to up to 1.82 times the control level. Notably, targeting lowly expressed subsets yielded spliced on-target reads 1.39 to 1.89 times the control. While these gains do not rival those achieved using chemical probe-based enrichment, they are sufficient to significantly enhance the power of downstream statistical analyses, such as testing for cell-type-specific isoform abundance. Specifically, compared to na\u00efve single-cell long-read sequencing, our approach yielded 2.42 times as many genes with significant differences in isoform usage between neurons and glia.

This clinical dilemma indicates that the traditional genotyping system based on genomics has not been able to fully resolve the molecular heterogeneity of acute myeloid leukemia (AML), and it is urgent to establish a precise stratified model that can dynamically reflect the functional status of tumor cells in the initial stage of treatment. In this study, Raman spectroscopy (RS) combined with machine learning algorithm was used to construct a metabolic prognosis prediction model for AML chemotherapy response. Bone marrow single cell Raman spectroscopy data of newly diagnosed AML patients were collected, and the molecular fingerprint was analyzed by principal component analysis linear discriminant analysis (PCA-LDA) and multivariate curve resolute alternating least square method (MCR-ALS). The results showed that the PCALDA model achieved complete remission or non-remission (CR/NR) classification through 24 principal components (cumulative variance contribution of 90.1%), the accuracy of external validation was 94.8% (sensitivity 97.9%, specificity 92.0%), and the AUC reached 96.27%.

Already, much is known about therapeutic targets and how they would need to be manipulated to mitigate disease. For such gene therapies to move to the clinic, potent CNS delivery vehicles are needed. One line of investigation focuses on adeno-associated viruses (AAV) to address this need. In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration. This review will introduce this topic and provide an update on recent developments. First, we describe the physical barriers that must be overcome for AAV-delivered gene therapies to reach target cells in the CNS. We then put a spotlight on the natural AAV9 capsid's inherent propensity to cross the BBB and key lessons learned from its use for delivering a therapeutic payload for the treatment of spinal muscular atrophy. Next, we summarize methods for engineering recombinant AAV (rAAV) capsids with improved brain penetrance, and present in vitro paradigms for predicting their capacity to cross the human BBB. We also present strategies for side-stepping the delivery limitations of existing rAAV vectors. Finally, we point toward a few notable clinical studies whose outcomes may advance our understanding of what rAAV-delivered gene therapies can offer to people afflicted with CNS disorders."

However, the causal relationship between impaired autophagy and ALS remains ambiguous, necessitating further elucidation. This Mendelian randomization (MR) study employs a two-sample design, utilizing genetic instruments to proxy autophagy dysregulation as the exposure and ALS as the outcome. It incorporates summary statistics of ALS (27,205 cases, 110,881 controls), along with data on DNA methylation, RNA splicing, gene expression, and protein abundance quantitative trait loci (QTLs) in both blood and brain tissues (mQTL, sQTL, eQTL, and pQTL, respectively) sourced from European cohorts. Cis-variants situated proximal to or within the 604 autophagy-related genes, exhibiting robust associations with molecular alterations in autophagy, are employed as instrumental variables. Their causal links with ALS are assessed via summary-data-based MR (SMR) analyses, followed by Bayesian colocalization, sensitivity analyses, brain cell-specific MR analyses, protein-protein interaction (PPI), and druggable analyses. Consistent evidence supported the causal effects of two lysosome genes (FNBP1 and IDUA), one autophagy core gene (C9orf72), and one mitophagy gene (USP35) on ALS risk. Specifically, brain FNBP1 splicing level (OR = 1.18, p = 3.38E-5) and blood USP35 expression level (OR = 1.17, p = 5.94E-5) were positively associated with higher ALS risk.

A major feature of TDP-43 pathology is its nuclear depletion, leading to the aberrant inclusion of cryptic exons during RNA splicing. STMN2 and UNC13A have emerged as prominent TDP-43 splicing targets, but the broader impact of TDP-43-dependent cryptic splicing on neuronal function remains unclear. Here, we report previously unidentified TDP-43 splicing targets critical for membrane excitability and synaptic function, including KALRN, RAP1GAP, SYT7, and KCNQ2. Using human stem cell-derived neurons, we showed that TDP-43 reduction induces cryptic splicing and down-regulation of these genes, resulting in impaired excitability and synaptic transmission. In postmortem brains from patients with FTD, these cryptic splicing events occurred selectively in neurons with TDP-43 pathology. Suppressing individual cryptic splicing events using antisense oligonucleotides partially restored neuronal function, and combined targeting almost fully rescued the synaptic deficit caused by TDP-43 loss. Together, our findings provide evidence that cryptic splicing in these synaptic and membrane excitability genes is not only a downstream marker but instead a direct driver of neuronal dysfunction, establishing a mechanistic link between TDP-43 pathology and neurodegeneration in ALS and FTD."

To decipher the underlying mechanisms responsible for these contradictions, we leverage emerging technologies that establish comprehensive cellular and spatiotemporal contexts for its signaling pathway. These approaches elucidate the mechanisms underlying central nervous system diseases and their potential therapeutic applications. In this review, we demonstrate how these advanced technologies enhance our understanding of the mechanism of activin A: CRISPR-based editing validates critical receptors such as ACVR1B in the process of remyelination; organoid and organ-on-a-chip systems model human-specific cellular interactions; spatial and single-cell multi-omics delineate expression and communication networks; and optogenetics/chemogenetics enable precise spatiotemporal control of signaling pathway activity. This technological toolkit provides a robust framework for elucidating the context-specific roles of activin A in conditions such as ischemic stroke, neurodegenerative diseases, glioma, epilepsy, and traumatic brain injury, encompassing key processes including neuroprotection, inflammation, and repair. Furthermore, these mechanistic insights inform next-generation interventions, including adeno-associated virus-mediated gene therapy for localized modulation and advanced nanodelivery systems for targeted biologic transport. Given these capabilities, artificial intelligence plays a crucial role in designing blood-brain barrier-permeable ligands and optimizing smart nanocarriers. By contrasting preclinical data with the clinical pipeline, which currently emphasizes peripheral diseases, we propose that integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement."

While both loss- and gain-of-function mechanisms contribute to disease, the discovery of cryptic splicing has shed light on the downstream consequences of TDP-43 nuclear clearance for neuronal health. Here, we highlight how loss of nuclear TDP-43 can drive a cascade of events that lead to the impairment of cellular proteostasis and result in a positive feedback loop that perpetuates neuronal dysfunction. This sustains the appearance of cryptic splicing events in genes that are involved in key pathways for the maintenance of axonal homeostasis and synaptic transmission. In contrast to their detrimental effects on neuronal health, cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies."

The existing therapies have only a small effect on alleviating symptoms, mainly because the therapeutic agents are difficult to cross the bloodbrain barrier. The purpose of the review is to discuss the potential of microneedle-based transdermal delivery systems to improve the delivery of drugs to the central nervous system and thereby manage neurodegenerative diseases effectively. The article summarizes and synthesizes the available literature that targets the strategies of microneedle-mediated drug delivery. The literature on the design, composition, pharmacokinetics, and mechanistic benefits of different microneedle platforms for surmounting central nervous system barriers was identified and thematically synthesized. Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier. Micro-needles can be used to deliver small molecules, peptides, and nanoparticles to the brain, thereby avoiding systemic side effects and enhancing drug bioavailability. Some of those designs include dissolving, coated, hollow, hydrogel-forming, and stimuli-responsive microneedles, which have been shown to target the brain and exhibit higher therapeutic efficiency in preclinical models. Although technological advances have improved, the clinical translation of microneedlebased strategies remains limited. The future directions could include using microneedles with stem cell-based therapies, CRISPR/Cas9 gene editing, artificial intelligence-based delivery systems, and responsive release technology to facilitate customized treatment. The Microneedle-based drug delivery systems are promising in overcoming the current limitations in the treatment of neurodegenerative diseases. Nonetheless, a large-scale clinical validation is necessary to guarantee safety, efficacy, and scalability to be applied to real-life scenarios."

However, current reviews often catalog virus-disease associations without integrating this evidence into a unified conceptual model that also accounts for the therapeutic potential of viral platforms. This review investigates recent literature to propose a \"dual-role\" model for viruses in NDDs. We analyze how diverse viruses (e.g., HSV-1, HIV, EBV, and SARS-CoV-2) converge on shared pathogenic pathways, including protein misfolding, chronic neuroinflammation, and mitochondrial dysfunction, across different NDDs. Paradoxically, engineered viral vectors derived from neurotropic viruses are being investigated as tools for targeted gene therapy. To address these therapeutic applications of viruses, this review also provides an in-depth report of the various viral vector technologies developed. The approaches involved in designing rationally engineered viral vectors based on various adeno-associated virus serotypes through rational design, directed evolution and machine learning strategies, as well as the lentiviral and herpes simplex virus-based platform are described. Different strategies that have been used to incorporate large and/or small payloads such as gene replacement, RNA interference, microRNA cassettes, CRISPR-based gene editing (base editing, prime editing, CRISPRa and CRISPRi) and the double AAV systems to deliver larger transgene cassette have also been reviewed. This review further includes various routes of administration including intrathecal, intracerebroventricular and convection-enhanced delivery with the use of Focused Ultrasound. The constraints imposed by the Blood-Brain Barrier are discussed, especially the approach using receptor-mediated transcytosis for crossing. The review also critically evaluates obstacles toward clinical translation of viral vectors due to various factors including immunogenicity, the presence of pre-existing neutralising antibodies and dose-dependent toxicity, illustrated by the fatal outcome of ASPIRO and DMD trials. Finally, this review concludes with other promising non-viral approaches such as lipid nanoparticle and extracellular vesicles. Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors."

Increasing evidence suggests that long non-coding RNAs (lncRNAs) play significant roles in neurodevelopment, neuronal homeostasis, and disease progression; however, their involvement in shared pathogenic pathways and clinical applications remains inadequately defined. This review consolidates recent experimental, transcriptomic, bioinformatic, and emerging clinical findings regarding the role of lncRNAs in NDDs. We examine how lncRNAs modulate common disease mechanisms, including protein misfolding and aggregation, neuroinflammation, mitochondrial dysfunction, ferroptosis, synaptic failure, and aging-related neurodegenerative processes. These regulatory functions occur through various mechanisms, including epigenetic modifications, transcriptional regulation, post-transcriptional processes, and RNA-protein interactions, as well as novel mechanisms such as liquid-liquid phase separation (LLPS), peptide coding, and exosome-mediated intercellular communication.\u00a0Current evidence supports the potential of lncRNAs as minimally invasive liquid biopsy biomarkers, detectable in blood, cerebrospinal fluid (CSF), and extracellular vesicles. Additionally, lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms. Overall, lncRNAs have emerged as central molecular regulators and promising candidates for translation in NDDs. Nonetheless, challenges related to specificity, validation, delivery across the blood-brain barrier, and clinical standardization must be addressed before their routine application in precision neurology."

Already, much is known about therapeutic targets and how they would need to be manipulated to mitigate disease. For such gene therapies to move to the clinic, potent CNS delivery vehicles are needed. One line of investigation focuses on adeno-associated viruses (AAV) to address this need. In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration. This review will introduce this topic and provide an update on recent developments. First, we describe the physical barriers that must be overcome for AAV-delivered gene therapies to reach target cells in the CNS. We then put a spotlight on the natural AAV9 capsid's inherent propensity to cross the BBB and key lessons learned from its use for delivering a therapeutic payload for the treatment of spinal muscular atrophy. Next, we summarize methods for engineering recombinant AAV (rAAV) capsids with improved brain penetrance, and present in vitro paradigms for predicting their capacity to cross the human BBB. We also present strategies for side-stepping the delivery limitations of existing rAAV vectors. Finally, we point toward a few notable clinical studies whose outcomes may advance our understanding of what rAAV-delivered gene therapies can offer to people afflicted with CNS disorders."

This mutation is a potential target for CRISPR/Cas9-based genome editing. However, the blood-brain barrier and limitations of current viral or nanoparticle-based delivery systems to neurons significantly restrict the clinical application of CRISPR-Cas9 in the brain. To address these challenges, we developed a drug delivery system using acerola-derived exosome-like nanoparticles (AELNs), which may overcome several limitations associated with human exosomes. AELNs stably form complexes with ribonucleoproteins (RNPs) comprised of Cas9 proteins and guide RNAs (gRNAs). We improved the delivery efficiency and selectivity of AELN/RNP complexes in GLP2-receptor-expressing neurons by incorporating GLP2 peptides into the AELN/RNP complexes. Intranasal administration of peptide-tagged AELN/RNP complexes in vivo confirmed the successful genome editing of C9orf72, demonstrating the potential of this system for treating neurodegenerative diseases.

We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology. We discuss the implications of a dynamic equilibrium of folded and unfolded rG4s in health and disease, with particular focus on their emerging roles in neurodegeneration."

Through CRISPR interference (CRISPRi) screening in human neurons, we identified the decapping scavenger enzyme (DCPS) as a novel genetic modifier of TDP-43 loss-of-function (LOF)-mediated neurotoxicity. Our findings reveal that TDP-43 LOF leads to aberrant mRNA degradation via dysregulating the properties and activity of processing bodies (P-bodies). TDP-43 interacts with P-body component proteins, potentially influencing their dynamic equilibrium and assembly into ribonucleoprotein (RNP) granules. Loss of TDP-43 hyperactivates P-bodies, increasing mRNA association and RNA decay. Reducing DCPS restores P-body integrity and RNA turnover, ultimately improving neuronal survival. Overall, this study highlights a novel role of TDP-43 in RNA processing through P-body regulation and identifies DCPS as a potential therapeutic target for TDP-43 proteinopathy-related neurodegenerative diseases."

As treatment for CNS disorders is primarily palliative, the underlying causes of disease progression are not addressed through conventional pharmacologic therapies. Gene therapy has the potential to address these root causes of disease progression; however, many of the vectors used in gene therapy (e.g., adeno-associated viruses (AAVs)) have limitations such as immunogenicity, low cargo capacity, and crossing the blood-brain barrier (BBB). These limitations have led to significant progress in the development of non-viral gene delivery systems. Compared with viral vectors, non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration. This review reports recent advancements in the development of non-viral platforms for CNS gene delivery and focuses on lipid-based nanoparticles, polymeric nanoparticles, exosome-based techniques, and new hybrid technologies. Particular emphasis is placed on nanoparticle modification approaches to enhance BBB penetration and enable delivery of genome-editing technologies (CRISPR/Cas systems). The review provides explanations of clinical trials, regulatory considerations, and manufacturing issues that result from the recent developments noted above.

A key driver of this pathogenesis is nuclear loss of ALS-associated protein TDP-43, leading to mis-splicing of TDP-43 targets including important neuronal genes STMN2 and UNC13A . Here, we have developed a gene therapy strategy for ALS and related TDP-43 proteinopathies, to correct mis-splicing of both STMN2 and UNC13A cryptic exons using small nuclear RNAs (snRNAs) encoded from a single vector. We identified promoter sequence elements to increase therapeutic snRNA expression by 10-fold, then further optimized the expression cassette with combinatorial snRNA targeting to rescue multiple cryptic splicing targets. The engineered snRNAs restored normal pre-mRNA processing of both STMN2 and UNC13A transcripts despite TDP-43 loss of function, rescuing stathmin-2 protein levels in iPSC derived motor neurons, restoring their axonal regeneration capacity to wild-type levels. In addition, adeno-associated virus (AAV) delivery of the snRNAs to the murine central nervous system in the constitutive cryptic splicing model Stmn2 Hum\u0394GU fully restored cortical Stmn2 pre-mRNA processing, highlighting the utility of snRNAs as a therapeutic modality in vivo .

However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation. This comprehensive review compares various CRISPR-Cas9 delivery vectors, viral, nonviral and physical, with a focus on their efficacy in neurological diseases such as AD. Viral vectors viz., adeno-associated viruses (AAVs) and lentiviruses (LVs) demonstrate high transduction efficiency and BBB permeability. AAVs are preferred for their low immunogenicity, minimal toxicity, high neuronal tropism and episomal persistence, enabling sustained expression without insertional mutagenesis. LVs offer larger genetic payloads but raise concerns about genomic integration and potential oncogenesis, though integration-defective variants mitigate these risks. Nonviral vectors, including peptide and polymer-based nanoparticles, lipid nanoparticles (LNPs) and Inorganic carriers such as gold and silver nanoparticles, are less immunogenic and easier to handle but require further optimisation for in\u00a0vivo BBB crossing and endosomal escape. Physical methods such as electroporation and microinjection are suitable for in\u00a0vitro/ex vivo use, while novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis. These preclinical studies show that these technologies can successfully edit genes and provide therapeutic benefits, including amyloid reduction and cognitive improvement in AD models. Yet off-target effects, immune responses and regulatory hurdles persist. Overall, continuous innovation in delivery vector design and safety profile-targeting strategies is crucial for advancing CRISPR-Cas9 towards clinical therapies for AD-based therapies and related neurological disorders."

CHCHD2 and CHCHD10 mutations caused neurodegeneration in model animals as seen in patients, but their pathophysiological roles remain elusive. Here we reported a direct role of CHCHD2 and CHCHD10 in autophagy. We identified a protein complex composing of CHCHD2-CHCHD10-C1QBP/p32-Atg8-family proteins (ATG8s), in which each molecule interacted with another. CHCHD2, CHCHD10 and C1QBP/p32 associated with ATG8s, preferentially, GABARAPs. Disease-associated CHCHD2 and CHCHD10 mutations exhibited varied interaction with ATG8s. By binding to GABARAPs, CHCHD2 and CHCHD10 underwent autophagic degradation, and recruited the ULK1 complex. Autophagy initiation defects occurred upon transient knockdown of CHCHD2, and also in human iPSC-derived CHCHD2-/- or CHCHD2T61I dopaminergic neurons.

Their biogenesis, molecular composition, and ability to traverse physiological barriers, including the blood-brain barrier, position exosomes as powerful candidates for biomarker development and therapeutic delivery in neurodegenerative diseases (NDDs). In Alzheimer's disease, Parkinson's disease, multiple sclerosis, and prion disorders, exosomes not only mirror pathological processes but actively participate in the propagation of misfolded proteins and neuroinflammatory signals through cell-type-specific vesicle subpopulations. This review synthesises current advances in exosome biology, cargo sorting, release mechanisms, and pathophysiological roles in the central nervous system, with emphasis on how neuron-, astrocyte-, and microglia-derived exosomes diverge in their cargo profiles and functional consequences across diseases. We highlight disease-specific exosomal signatures, including amyloid-\u03b2 (A\u03b2), tau, \u03b1-synuclein, myelin proteins, prion proteins (PrP) and regulatory microRNAs. We evaluate emerging technologies such as microfluidic isolation, single-vesicle analysis, and multi-omics profiling that are accelerating biomarker discovery, and review exosome-based therapeutic strategies, including native stem cell-derived exosomes and surface-engineered vesicles loaded with neuroprotective miRNAs, small molecules, and gene-editing cargo. We address critical unmet challenges in translating these approaches to the clinic, including scalable and standardised production, incomplete pharmacokinetic /pharmacodynamic characterisation in preclinical models, immunogenicity and off-target safety concerns, and the absence of specific regulatory guidance for EV drug products. Together, these insights highlight the transformative potential of exosomes as both precision diagnostic tools and disease-modifying therapeutic platforms for NDDs."

While its cytoplasmic aggregation is the pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD), recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure. Under healthy conditions, TDP-43 forms dimers via its N-terminal domain, a configuration that is crucial for its nuclear solubility and cooperative RNA binding. In this review, we propose the \"Molecular Zipper\" hypothesis to describe the maintenance of TDP-43 structural homeostasis. In this framework, the N-terminal domain acts as a stabilizing \"NTD-mediated anchor\" that keeps the protein in a functional, \"zipped\" dimeric state, effectively sequestering its aggregation-prone C-terminal regions. Pathogenic triggers-including genetic mutations, aberrant post-translational modifications such as phosphorylation and acetylation, and environmental stressors-can \"unzip\" this structure, leading to the formation of pathogenic monomers. These pathogenic monomers show increased propensity for cytoplasmic mislocalization and recruit wild-type protein into aggregates through a prion-like seeded aggregation mechanism, culminating in nuclear functional loss and cytoplasmic gain-of-toxicity. We further evaluate the emerging diagnostic landscape, focusing on methods to monitor the dimer-to-monomer ratio. Integrating prior biochemical data on TDP-43 dimerization with structural modeling enables a more coherent account of the transition from the physiological dimer to pathological conformers. The Molecular Zipper framework offers a conceptual foundation for reconciling existing experimental findings and for guiding future studies on early structural changes in TDP-43 proteinopathy."

While both loss- and gain-of-function mechanisms contribute to disease, the discovery of cryptic splicing has shed light on the downstream consequences of TDP-43 nuclear clearance for neuronal health. Here, we highlight how loss of nuclear TDP-43 can drive a cascade of events that lead to the impairment of cellular proteostasis and result in a positive feedback loop that perpetuates neuronal dysfunction. This sustains the appearance of cryptic splicing events in genes that are involved in key pathways for the maintenance of axonal homeostasis and synaptic transmission. In contrast to their detrimental effects on neuronal health, cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies."

To decipher the underlying mechanisms responsible for these contradictions, we leverage emerging technologies that establish comprehensive cellular and spatiotemporal contexts for its signaling pathway. These approaches elucidate the mechanisms underlying central nervous system diseases and their potential therapeutic applications. In this review, we demonstrate how these advanced technologies enhance our understanding of the mechanism of activin A: CRISPR-based editing validates critical receptors such as ACVR1B in the process of remyelination; organoid and organ-on-a-chip systems model human-specific cellular interactions; spatial and single-cell multi-omics delineate expression and communication networks; and optogenetics/chemogenetics enable precise spatiotemporal control of signaling pathway activity. This technological toolkit provides a robust framework for elucidating the context-specific roles of activin A in conditions such as ischemic stroke, neurodegenerative diseases, glioma, epilepsy, and traumatic brain injury, encompassing key processes including neuroprotection, inflammation, and repair. Furthermore, these mechanistic insights inform next-generation interventions, including adeno-associated virus-mediated gene therapy for localized modulation and advanced nanodelivery systems for targeted biologic transport. Given these capabilities, artificial intelligence plays a crucial role in designing blood-brain barrier-permeable ligands and optimizing smart nanocarriers. By contrasting preclinical data with the clinical pipeline, which currently emphasizes peripheral diseases, we propose that integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement."

The existing therapies have only a small effect on alleviating symptoms, mainly because the therapeutic agents are difficult to cross the bloodbrain barrier. The purpose of the review is to discuss the potential of microneedle-based transdermal delivery systems to improve the delivery of drugs to the central nervous system and thereby manage neurodegenerative diseases effectively. The article summarizes and synthesizes the available literature that targets the strategies of microneedle-mediated drug delivery. The literature on the design, composition, pharmacokinetics, and mechanistic benefits of different microneedle platforms for surmounting central nervous system barriers was identified and thematically synthesized. Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier. Micro-needles can be used to deliver small molecules, peptides, and nanoparticles to the brain, thereby avoiding systemic side effects and enhancing drug bioavailability. Some of those designs include dissolving, coated, hollow, hydrogel-forming, and stimuli-responsive microneedles, which have been shown to target the brain and exhibit higher therapeutic efficiency in preclinical models. Although technological advances have improved, the clinical translation of microneedlebased strategies remains limited. The future directions could include using microneedles with stem cell-based therapies, CRISPR/Cas9 gene editing, artificial intelligence-based delivery systems, and responsive release technology to facilitate customized treatment. The Microneedle-based drug delivery systems are promising in overcoming the current limitations in the treatment of neurodegenerative diseases. Nonetheless, a large-scale clinical validation is necessary to guarantee safety, efficacy, and scalability to be applied to real-life scenarios."

However, current reviews often catalog virus-disease associations without integrating this evidence into a unified conceptual model that also accounts for the therapeutic potential of viral platforms. This review investigates recent literature to propose a \"dual-role\" model for viruses in NDDs. We analyze how diverse viruses (e.g., HSV-1, HIV, EBV, and SARS-CoV-2) converge on shared pathogenic pathways, including protein misfolding, chronic neuroinflammation, and mitochondrial dysfunction, across different NDDs. Paradoxically, engineered viral vectors derived from neurotropic viruses are being investigated as tools for targeted gene therapy. To address these therapeutic applications of viruses, this review also provides an in-depth report of the various viral vector technologies developed. The approaches involved in designing rationally engineered viral vectors based on various adeno-associated virus serotypes through rational design, directed evolution and machine learning strategies, as well as the lentiviral and herpes simplex virus-based platform are described. Different strategies that have been used to incorporate large and/or small payloads such as gene replacement, RNA interference, microRNA cassettes, CRISPR-based gene editing (base editing, prime editing, CRISPRa and CRISPRi) and the double AAV systems to deliver larger transgene cassette have also been reviewed. This review further includes various routes of administration including intrathecal, intracerebroventricular and convection-enhanced delivery with the use of Focused Ultrasound. The constraints imposed by the Blood-Brain Barrier are discussed, especially the approach using receptor-mediated transcytosis for crossing. The review also critically evaluates obstacles toward clinical translation of viral vectors due to various factors including immunogenicity, the presence of pre-existing neutralising antibodies and dose-dependent toxicity, illustrated by the fatal outcome of ASPIRO and DMD trials. Finally, this review concludes with other promising non-viral approaches such as lipid nanoparticle and extracellular vesicles. Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors."

Increasing evidence suggests that long non-coding RNAs (lncRNAs) play significant roles in neurodevelopment, neuronal homeostasis, and disease progression; however, their involvement in shared pathogenic pathways and clinical applications remains inadequately defined. This review consolidates recent experimental, transcriptomic, bioinformatic, and emerging clinical findings regarding the role of lncRNAs in NDDs. We examine how lncRNAs modulate common disease mechanisms, including protein misfolding and aggregation, neuroinflammation, mitochondrial dysfunction, ferroptosis, synaptic failure, and aging-related neurodegenerative processes. These regulatory functions occur through various mechanisms, including epigenetic modifications, transcriptional regulation, post-transcriptional processes, and RNA-protein interactions, as well as novel mechanisms such as liquid-liquid phase separation (LLPS), peptide coding, and exosome-mediated intercellular communication.\u00a0Current evidence supports the potential of lncRNAs as minimally invasive liquid biopsy biomarkers, detectable in blood, cerebrospinal fluid (CSF), and extracellular vesicles. Additionally, lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms. Overall, lncRNAs have emerged as central molecular regulators and promising candidates for translation in NDDs. Nonetheless, challenges related to specificity, validation, delivery across the blood-brain barrier, and clinical standardization must be addressed before their routine application in precision neurology."

Already, much is known about therapeutic targets and how they would need to be manipulated to mitigate disease. For such gene therapies to move to the clinic, potent CNS delivery vehicles are needed. One line of investigation focuses on adeno-associated viruses (AAV) to address this need. In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration. This review will introduce this topic and provide an update on recent developments. First, we describe the physical barriers that must be overcome for AAV-delivered gene therapies to reach target cells in the CNS. We then put a spotlight on the natural AAV9 capsid's inherent propensity to cross the BBB and key lessons learned from its use for delivering a therapeutic payload for the treatment of spinal muscular atrophy. Next, we summarize methods for engineering recombinant AAV (rAAV) capsids with improved brain penetrance, and present in vitro paradigms for predicting their capacity to cross the human BBB. We also present strategies for side-stepping the delivery limitations of existing rAAV vectors. Finally, we point toward a few notable clinical studies whose outcomes may advance our understanding of what rAAV-delivered gene therapies can offer to people afflicted with CNS disorders."

This mutation is a potential target for CRISPR/Cas9-based genome editing. However, the blood-brain barrier and limitations of current viral or nanoparticle-based delivery systems to neurons significantly restrict the clinical application of CRISPR-Cas9 in the brain. To address these challenges, we developed a drug delivery system using acerola-derived exosome-like nanoparticles (AELNs), which may overcome several limitations associated with human exosomes. AELNs stably form complexes with ribonucleoproteins (RNPs) comprised of Cas9 proteins and guide RNAs (gRNAs). We improved the delivery efficiency and selectivity of AELN/RNP complexes in GLP2-receptor-expressing neurons by incorporating GLP2 peptides into the AELN/RNP complexes. Intranasal administration of peptide-tagged AELN/RNP complexes in vivo confirmed the successful genome editing of C9orf72, demonstrating the potential of this system for treating neurodegenerative diseases.

We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology. We discuss the implications of a dynamic equilibrium of folded and unfolded rG4s in health and disease, with particular focus on their emerging roles in neurodegeneration."

Through CRISPR interference (CRISPRi) screening in human neurons, we identified the decapping scavenger enzyme (DCPS) as a novel genetic modifier of TDP-43 loss-of-function (LOF)-mediated neurotoxicity. Our findings reveal that TDP-43 LOF leads to aberrant mRNA degradation via dysregulating the properties and activity of processing bodies (P-bodies). TDP-43 interacts with P-body component proteins, potentially influencing their dynamic equilibrium and assembly into ribonucleoprotein (RNP) granules. Loss of TDP-43 hyperactivates P-bodies, increasing mRNA association and RNA decay. Reducing DCPS restores P-body integrity and RNA turnover, ultimately improving neuronal survival.

As treatment for CNS disorders is primarily palliative, the underlying causes of disease progression are not addressed through conventional pharmacologic therapies. Gene therapy has the potential to address these root causes of disease progression; however, many of the vectors used in gene therapy (e.g., adeno-associated viruses (AAVs)) have limitations such as immunogenicity, low cargo capacity, and crossing the blood-brain barrier (BBB). These limitations have led to significant progress in the development of non-viral gene delivery systems.

Particular emphasis is placed on nanoparticle modification approaches to enhance BBB penetration and enable delivery of genome-editing technologies (CRISPR/Cas systems). The review provides explanations of clinical trials, regulatory considerations, and manufacturing issues that result from the recent developments noted above.

A key driver of this pathogenesis is nuclear loss of ALS-associated protein TDP-43, leading to mis-splicing of TDP-43 targets including important neuronal genes STMN2 and UNC13A . Here, we have developed a gene therapy strategy for ALS and related TDP-43 proteinopathies, to correct mis-splicing of both STMN2 and UNC13A cryptic exons using small nuclear RNAs (snRNAs) encoded from a single vector. We identified promoter sequence elements to increase therapeutic snRNA expression by 10-fold, then further optimized the expression cassette with combinatorial snRNA targeting to rescue multiple cryptic splicing targets. The engineered snRNAs restored normal pre-mRNA processing of both STMN2 and UNC13A transcripts despite TDP-43 loss of function, rescuing stathmin-2 protein levels in iPSC derived motor neurons, restoring their axonal regeneration capacity to wild-type levels.

However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation. This comprehensive review compares various CRISPR-Cas9 delivery vectors, viral, nonviral and physical, with a focus on their efficacy in neurological diseases such as AD. Viral vectors viz., adeno-associated viruses (AAVs) and lentiviruses (LVs) demonstrate high transduction efficiency and BBB permeability. AAVs are preferred for their low immunogenicity, minimal toxicity, high neuronal tropism and episomal persistence, enabling sustained expression without insertional mutagenesis. LVs offer larger genetic payloads but raise concerns about genomic integration and potential oncogenesis, though integration-defective variants mitigate these risks. Nonviral vectors, including peptide and polymer-based nanoparticles, lipid nanoparticles (LNPs) and Inorganic carriers such as gold and silver nanoparticles, are less immunogenic and easier to handle but require further optimisation for in\u00a0vivo BBB crossing and endosomal escape. Physical methods such as electroporation and microinjection are suitable for in\u00a0vitro/ex vivo use, while novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis.

CHCHD2 and CHCHD10 mutations caused neurodegeneration in model animals as seen in patients, but their pathophysiological roles remain elusive. Here we reported a direct role of CHCHD2 and CHCHD10 in autophagy. We identified a protein complex composing of CHCHD2-CHCHD10-C1QBP/p32-Atg8-family proteins (ATG8s), in which each molecule interacted with another. CHCHD2, CHCHD10 and C1QBP/p32 associated with ATG8s, preferentially, GABARAPs. Disease-associated CHCHD2 and CHCHD10 mutations exhibited varied interaction with ATG8s. By binding to GABARAPs, CHCHD2 and CHCHD10 underwent autophagic degradation, and recruited the ULK1 complex. Autophagy initiation defects occurred upon transient knockdown of CHCHD2, and also in human iPSC-derived CHCHD2-/- or CHCHD2T61I dopaminergic neurons. Importantly, CHCHD2 and CHCHD10 promoted autophagy. CHCHD2 reduced protein aggregates in cells and toxic SNCA/\u03b1-synuclein species in mouse striatum.

The authors of this review article present a summary of the current understanding of the relationship of gut microbiome, exosome biogenesis, and the pathophysiological development of neurodegenerative diseases. Evidence from laboratory studies, animal studies, and newly emerging human studies suggests that microbiome-based metabolites and inflammatory mediators may modulate how exosomes are produced, what they carry, and how they interact with the blood-brain barrier. These exosomal signals may impact neuroinflammation, neuronal signaling, and the spread of pathological proteins of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease. In addition, they examine some possible ways to target the gut-brain axis from a therapeutic perspective, including manipulating the gut microbiome, providing probiotics and/or prebiotics, performing fecal microbiota transplantation, and/or using engineered extracellular vesicles as vehicles for drug delivery. The authors also outline some of the methodological differences that make it difficult to assess the effects of exosomes."

While tools like alevin-fry and simpleaf (and augmented execution context for the alevin-fry), offer flexibility and computational efficiency to process single-cell data, this ecosystem will further benefit from a standardized QC reporting tailored for its outputs. We introduce QCatch, a Python-based command-line tool that generates comprehensive and interactive HTML QC reports designed specifically for single-cell quantification results. Taking the output directory of alevin-fry or simpleaf as the input, QCatch is able to perform essential processing steps, like cell calling, and generate detailed QC reports that contain informative visualizations and statistics, including unique molecular identifier (UMI) count distributions, sequencing saturation estimates, and splicing status information, for QC assurance. Built for seamless integration into downstream analysis workflows, QCatch exports the processed results in a richly-annotated H5AD format file, a widely used data format common among many downstream single-cell data analysis tools.

Nucleic-acid therapeutics\u2014including antisense oligonucleotides, RNA interference, messenger RNA, and CRISPR-based genome editing\u2014offer programmable control over oncogenic drivers and immune pathways, yet their clinical translation is hindered by rapid nuclease degradation, systemic clearance, restricted blood\u2013brain-barrier transport, inefficient cellular uptake, and endosomal entrapment. Recent progress in nanotechnology has enabled the rational design of nanoparticle platforms that overcome these multilayered biological obstacles. This review summarizes advances (2022\u20132025) in lipid and biomimetic nanocarriers engineered to enhance nucleic-acid delivery for GBM therapy. For instance, ionizable lipid nanoparticles with pH-responsive chemistry and optimized head-group design achieve efficient cytosolic release with improved biocompatibility, while biomimetic systems, such as cell-membrane-, lipoprotein-, virus-, DNA-, and exosome-mimicking platforms, leverage natural transport and recognition pathways for tumor-specific targeting and immune evasion. Finally, we discuss translational considerations, including GMP-compatible manufacturing, batch consistency, long-term safety and immunogenicity, and advanced model selection, and outline future opportunities in high-throughput lipid discovery, AI-assisted ligand design, hydrogel-mediated spatiotemporal release, and patient-tailored nanotherapies. Collectively, these emerging nanocarriers offer a convergent strategy to navigate physiological barriers and advance precision nucleic-acid therapeutics against glioblastoma."

However, the main cellular mechanisms and cell death pathways leading to motor neuron degeneration have not yet been clarified. Research indicates evidence of ferroptosis in ALS, and the natural compound kaempferol has been demonstrated to inhibit neuronal ferroptosis. However, damage to the blood-brain barrier (BBB) prevents the drug from penetrating the central nervous system, which significantly reduces its therapeutic efficacy. Here, we developed a targeted delivery system named Eda/Kae@Lip-RGD (EKLR), which consisted of liposome-grafted RGD peptides for the co-delivery of the drugs kaempferol and edaravone, capable of crossing the BBB to provide co-delivery of kaempferol and edaravone for combined treatment of ALS. As expected, treatment with EKLR for one month significantly slowed down weight loss and improved athletic performance in SOD1G93A transgenic mice. Mechanistically, this nanomedicine suppressed ferroptosis by upregulating the antioxidant proteins GPX4 and SLC7A11, alongside the downregulation of Nrf2 and ACSL4 levels, thus collectively preserving neuronal integrity. Meanwhile, EKLR restored the normal morphology and the survival rate of neurons and maintained the mitochondrial structure and morphological integrity. Accordingly, this nanoplatform may represent a distinctive and potentially effective strategy for achieving neuroprotection in ALS as well as in other disorders of the central nervous system."

While its cytoplasmic aggregation is the pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD), recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure. Under healthy conditions, TDP-43 forms dimers via its N-terminal domain, a configuration that is crucial for its nuclear solubility and cooperative RNA binding. In this review, we propose the \"Molecular Zipper\" hypothesis to describe the maintenance of TDP-43 structural homeostasis. In this framework, the N-terminal domain acts as a stabilizing \"NTD-mediated anchor\" that keeps the protein in a functional, \"zipped\" dimeric state, effectively sequestering its aggregation-prone C-terminal regions. Pathogenic triggers-including genetic mutations, aberrant post-translational modifications such as phosphorylation and acetylation, and environmental stressors-can \"unzip\" this structure, leading to the formation of pathogenic monomers. These pathogenic monomers show increased propensity for cytoplasmic mislocalization and recruit wild-type protein into aggregates through a prion-like seeded aggregation mechanism, culminating in nuclear functional loss and cytoplasmic gain-of-toxicity. We further evaluate the emerging diagnostic landscape, focusing on methods to monitor the dimer-to-monomer ratio. Integrating prior biochemical data on TDP-43 dimerization with structural modeling enables a more coherent account of the transition from the physiological dimer to pathological conformers. The Molecular Zipper framework offers a conceptual foundation for reconciling existing experimental findings and for guiding future studies on early structural changes in TDP-43 proteinopathy."

While both loss- and gain-of-function mechanisms contribute to disease, the discovery of cryptic splicing has shed light on the downstream consequences of TDP-43 nuclear clearance for neuronal health. Here, we highlight how loss of nuclear TDP-43 can drive a cascade of events that lead to the impairment of cellular proteostasis and result in a positive feedback loop that perpetuates neuronal dysfunction. This sustains the appearance of cryptic splicing events in genes that are involved in key pathways for the maintenance of axonal homeostasis and synaptic transmission. In contrast to their detrimental effects on neuronal health, cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies."

To decipher the underlying mechanisms responsible for these contradictions, we leverage emerging technologies that establish comprehensive cellular and spatiotemporal contexts for its signaling pathway. These approaches elucidate the mechanisms underlying central nervous system diseases and their potential therapeutic applications. In this review, we demonstrate how these advanced technologies enhance our understanding of the mechanism of activin A: CRISPR-based editing validates critical receptors such as ACVR1B in the process of remyelination; organoid and organ-on-a-chip systems model human-specific cellular interactions; spatial and single-cell multi-omics delineate expression and communication networks; and optogenetics/chemogenetics enable precise spatiotemporal control of signaling pathway activity. This technological toolkit provides a robust framework for elucidating the context-specific roles of activin A in conditions such as ischemic stroke, neurodegenerative diseases, glioma, epilepsy, and traumatic brain injury, encompassing key processes including neuroprotection, inflammation, and repair. Furthermore, these mechanistic insights inform next-generation interventions, including adeno-associated virus-mediated gene therapy for localized modulation and advanced nanodelivery systems for targeted biologic transport. Given these capabilities, artificial intelligence plays a crucial role in designing blood-brain barrier-permeable ligands and optimizing smart nanocarriers. By contrasting preclinical data with the clinical pipeline, which currently emphasizes peripheral diseases, we propose that integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement."

The existing therapies have only a small effect on alleviating symptoms, mainly because the therapeutic agents are difficult to cross the bloodbrain barrier. The purpose of the review is to discuss the potential of microneedle-based transdermal delivery systems to improve the delivery of drugs to the central nervous system and thereby manage neurodegenerative diseases effectively. The article summarizes and synthesizes the available literature that targets the strategies of microneedle-mediated drug delivery. The literature on the design, composition, pharmacokinetics, and mechanistic benefits of different microneedle platforms for surmounting central nervous system barriers was identified and thematically synthesized. Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier. Micro-needles can be used to deliver small molecules, peptides, and nanoparticles to the brain, thereby avoiding systemic side effects and enhancing drug bioavailability. Some of those designs include dissolving, coated, hollow, hydrogel-forming, and stimuli-responsive microneedles, which have been shown to target the brain and exhibit higher therapeutic efficiency in preclinical models. Although technological advances have improved, the clinical translation of microneedlebased strategies remains limited. The future directions could include using microneedles with stem cell-based therapies, CRISPR/Cas9 gene editing, artificial intelligence-based delivery systems, and responsive release technology to facilitate customized treatment. The Microneedle-based drug delivery systems are promising in overcoming the current limitations in the treatment of neurodegenerative diseases. Nonetheless, a large-scale clinical validation is necessary to guarantee safety, efficacy, and scalability to be applied to real-life scenarios."

However, current reviews often catalog virus-disease associations without integrating this evidence into a unified conceptual model that also accounts for the therapeutic potential of viral platforms. This review investigates recent literature to propose a \"dual-role\" model for viruses in NDDs. We analyze how diverse viruses (e.g., HSV-1, HIV, EBV, and SARS-CoV-2) converge on shared pathogenic pathways, including protein misfolding, chronic neuroinflammation, and mitochondrial dysfunction, across different NDDs. Paradoxically, engineered viral vectors derived from neurotropic viruses are being investigated as tools for targeted gene therapy. To address these therapeutic applications of viruses, this review also provides an in-depth report of the various viral vector technologies developed. The approaches involved in designing rationally engineered viral vectors based on various adeno-associated virus serotypes through rational design, directed evolution and machine learning strategies, as well as the lentiviral and herpes simplex virus-based platform are described. Different strategies that have been used to incorporate large and/or small payloads such as gene replacement, RNA interference, microRNA cassettes, CRISPR-based gene editing (base editing, prime editing, CRISPRa and CRISPRi) and the double AAV systems to deliver larger transgene cassette have also been reviewed. This review further includes various routes of administration including intrathecal, intracerebroventricular and convection-enhanced delivery with the use of Focused Ultrasound. The constraints imposed by the Blood-Brain Barrier are discussed, especially the approach using receptor-mediated transcytosis for crossing. The review also critically evaluates obstacles toward clinical translation of viral vectors due to various factors including immunogenicity, the presence of pre-existing neutralising antibodies and dose-dependent toxicity, illustrated by the fatal outcome of ASPIRO and DMD trials. Finally, this review concludes with other promising non-viral approaches such as lipid nanoparticle and extracellular vesicles. Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors."

Increasing evidence suggests that long non-coding RNAs (lncRNAs) play significant roles in neurodevelopment, neuronal homeostasis, and disease progression; however, their involvement in shared pathogenic pathways and clinical applications remains inadequately defined. This review consolidates recent experimental, transcriptomic, bioinformatic, and emerging clinical findings regarding the role of lncRNAs in NDDs. We examine how lncRNAs modulate common disease mechanisms, including protein misfolding and aggregation, neuroinflammation, mitochondrial dysfunction, ferroptosis, synaptic failure, and aging-related neurodegenerative processes. These regulatory functions occur through various mechanisms, including epigenetic modifications, transcriptional regulation, post-transcriptional processes, and RNA-protein interactions, as well as novel mechanisms such as liquid-liquid phase separation (LLPS), peptide coding, and exosome-mediated intercellular communication.\u00a0Current evidence supports the potential of lncRNAs as minimally invasive liquid biopsy biomarkers, detectable in blood, cerebrospinal fluid (CSF), and extracellular vesicles. Additionally, lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms. Overall, lncRNAs have emerged as central molecular regulators and promising candidates for translation in NDDs.

Already, much is known about therapeutic targets and how they would need to be manipulated to mitigate disease. For such gene therapies to move to the clinic, potent CNS delivery vehicles are needed. One line of investigation focuses on adeno-associated viruses (AAV) to address this need. In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration. This review will introduce this topic and provide an update on recent developments. First, we describe the physical barriers that must be overcome for AAV-delivered gene therapies to reach target cells in the CNS. We then put a spotlight on the natural AAV9 capsid's inherent propensity to cross the BBB and key lessons learned from its use for delivering a therapeutic payload for the treatment of spinal muscular atrophy. Next, we summarize methods for engineering recombinant AAV (rAAV) capsids with improved brain penetrance, and present in vitro paradigms for predicting their capacity to cross the human BBB. We also present strategies for side-stepping the delivery limitations of existing rAAV vectors. Finally, we point toward a few notable clinical studies whose outcomes may advance our understanding of what rAAV-delivered gene therapies can offer to people afflicted with CNS disorders."

AELNs stably form complexes with ribonucleoproteins (RNPs) comprised of Cas9 proteins and guide RNAs (gRNAs). We improved the delivery efficiency and selectivity of AELN/RNP complexes in GLP2-receptor-expressing neurons by incorporating GLP2 peptides into the AELN/RNP complexes.

We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology.

Through CRISPR interference (CRISPRi) screening in human neurons, we identified the decapping scavenger enzyme (DCPS) as a novel genetic modifier of TDP-43 loss-of-function (LOF)-mediated neurotoxicity. Our findings reveal that TDP-43 LOF leads to aberrant mRNA degradation via dysregulating the properties and activity of processing bodies (P-bodies). TDP-43 interacts with P-body component proteins, potentially influencing their dynamic equilibrium and assembly into ribonucleoprotein (RNP) granules. Loss of TDP-43 hyperactivates P-bodies, increasing mRNA association and RNA decay. Reducing DCPS restores P-body integrity and RNA turnover, ultimately improving neuronal survival.

As treatment for CNS disorders is primarily palliative, the underlying causes of disease progression are not addressed through conventional pharmacologic therapies. Gene therapy has the potential to address these root causes of disease progression; however, many of the vectors used in gene therapy (e.g., adeno-associated viruses (AAVs)) have limitations such as immunogenicity, low cargo capacity, and crossing the blood-brain barrier (BBB). These limitations have led to significant progress in the development of non-viral gene delivery systems.

A key driver of this pathogenesis is nuclear loss of ALS-associated protein TDP-43, leading to mis-splicing of TDP-43 targets including important neuronal genes STMN2 and UNC13A . Here, we have developed a gene therapy strategy for ALS and related TDP-43 proteinopathies, to correct mis-splicing of both STMN2 and UNC13A cryptic exons using small nuclear RNAs (snRNAs) encoded from a single vector. We identified promoter sequence elements to increase therapeutic snRNA expression by 10-fold, then further optimized the expression cassette with combinatorial snRNA targeting to rescue multiple cryptic splicing targets. The engineered snRNAs restored normal pre-mRNA processing of both STMN2 and UNC13A transcripts despite TDP-43 loss of function, rescuing stathmin-2 protein levels in iPSC derived motor neurons, restoring their axonal regeneration capacity to wild-type levels.

However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation. This comprehensive review compares various CRISPR-Cas9 delivery vectors, viral, nonviral and physical, with a focus on their efficacy in neurological diseases such as AD. Viral vectors viz., adeno-associated viruses (AAVs) and lentiviruses (LVs) demonstrate high transduction efficiency and BBB permeability. AAVs are preferred for their low immunogenicity, minimal toxicity, high neuronal tropism and episomal persistence, enabling sustained expression without insertional mutagenesis. LVs offer larger genetic payloads but raise concerns about genomic integration and potential oncogenesis, though integration-defective variants mitigate these risks. Nonviral vectors, including peptide and polymer-based nanoparticles, lipid nanoparticles (LNPs) and Inorganic carriers such as gold and silver nanoparticles, are less immunogenic and easier to handle but require further optimisation for in\u00a0vivo BBB crossing and endosomal escape. Physical methods such as electroporation and microinjection are suitable for in\u00a0vitro/ex vivo use, while novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis.

CHCHD2 and CHCHD10 mutations caused neurodegeneration in model animals as seen in patients, but their pathophysiological roles remain elusive. Here we reported a direct role of CHCHD2 and CHCHD10 in autophagy. We identified a protein complex composing of CHCHD2-CHCHD10-C1QBP/p32-Atg8-family proteins (ATG8s), in which each molecule interacted with another. CHCHD2, CHCHD10 and C1QBP/p32 associated with ATG8s, preferentially, GABARAPs. Disease-associated CHCHD2 and CHCHD10 mutations exhibited varied interaction with ATG8s. By binding to GABARAPs, CHCHD2 and CHCHD10 underwent autophagic degradation, and recruited the ULK1 complex. Autophagy initiation defects occurred upon transient knockdown of CHCHD2, and also in human iPSC-derived CHCHD2-/- or CHCHD2T61I dopaminergic neurons. Importantly, CHCHD2 and CHCHD10 promoted autophagy. CHCHD2 reduced protein aggregates in cells and toxic SNCA/\u03b1-synuclein species in mouse striatum. Our study thus revealed mitochondrial proteins CHCHD2 and CHCHD10 as both autophagy substrates and autophagy activators and laid groundwork for therapy targeting patients with neurodegeneration.Abbreviations: AA: amino acid; AD: Alzheimer disease; ALS: amyotrophic lateral sclerosis; ATG5: autophagy related 5; ATG7: autophagy related 7; ATG8: mammalian Atg8-family protein; ATG13: autophagy related 13; bafA1: bafilomycin A1; C1QBP/p32/gC1qR/HABP1: complement component 1, q subcomponent binding protein; CHCHD2/MNRR1/MIX17B: coiled-coil-helix-coiled-coil-helix domain containing 2; CHCHD10/MIX17A: coiled-coil-helix-coiled-coil-helix domain containing 10; CHX: cycloheximide; CMA: chaperone-mediated autophagy; CRISPR: clustered regularly interspaced short palindromic repeats; CQ, chloroquine; DA: dopaminergic; DMSO: dimethyl sulfoxide; EBSS: Earle's balanced salt solution; RB1CC1/FIP200: RB1 inducible coiled-coil 1; FTD: frontotemporal dementia; GABARAP: gamma-aminobutyric acid receptorbassociated protein; GABARAPL1: GABA type A receptor associated protein like 1; GABARAPL2: GABA type A receptor associated protein like 2; hESC: human embryonic stem cells; iPSC: induced pluripotent stem cell; KO: knockout; LAMP1: lysosomal-associated membrane protein 1; LAMP2A: lysosomal-associated membrane protein 2A; MAP1LC3/LC3: microtubule-associated protein 1 light chain 3; LIR: LC3-interacting region; PD: Parkinson disease; SQSTM1/p62: sequestosome 1; TARDBP/TDP-43: TAR DNA binding protein; TH: tyrosine hydroxylase; TMR, tetramethylrhodamine; WT: wild type; UB: ubiquitin; ULK1: unc-51 like kinase 1."

Extracellular vesicles, particularly exosomes, that move bioactive substances between the stomach and the brain, such as proteins, lipids, metabolites, and microRNAs, may improve the gut-brain axis. In the past years, the role of exosome-mediated communication has been recognized as significant in relation to the etiology, continued progression, and potential treatment of neurodegenerative disorders. The authors of this review article present a summary of the current understanding of the relationship of gut microbiome, exosome biogenesis, and the pathophysiological development of neurodegenerative diseases. Evidence from laboratory studies, animal studies, and newly emerging human studies suggests that microbiome-based metabolites and inflammatory mediators may modulate how exosomes are produced, what they carry, and how they interact with the blood-brain barrier. These exosomal signals may impact neuroinflammation, neuronal signaling, and the spread of pathological proteins of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease. In addition, they examine some possible ways to target the gut-brain axis from a therapeutic perspective, including manipulating the gut microbiome, providing probiotics and/or prebiotics, performing fecal microbiota transplantation, and/or using engineered extracellular vesicles as vehicles for drug delivery. The authors also outline some of the methodological differences that make it difficult to assess the effects of exosomes."

We introduce QCatch, a Python-based command-line tool that generates comprehensive and interactive HTML QC reports designed specifically for single-cell quantification results. Taking the output directory of alevin-fry or simpleaf as the input, QCatch is able to perform essential processing steps, like cell calling, and generate detailed QC reports that contain informative visualizations and statistics, including unique molecular identifier (UMI) count distributions, sequencing saturation estimates, and splicing status information, for QC assurance. Built for seamless integration into downstream analysis workflows, QCatch exports the processed results in a richly-annotated H5AD format file, a widely used data format common among many downstream single-cell data analysis tools.

Nucleic-acid therapeutics\u2014including antisense oligonucleotides, RNA interference, messenger RNA, and CRISPR-based genome editing\u2014offer programmable control over oncogenic drivers and immune pathways, yet their clinical translation is hindered by rapid nuclease degradation, systemic clearance, restricted blood\u2013brain-barrier transport, inefficient cellular uptake, and endosomal entrapment. Recent progress in nanotechnology has enabled the rational design of nanoparticle platforms that overcome these multilayered biological obstacles. This review summarizes advances (2022\u20132025) in lipid and biomimetic nanocarriers engineered to enhance nucleic-acid delivery for GBM therapy. For instance, ionizable lipid nanoparticles with pH-responsive chemistry and optimized head-group design achieve efficient cytosolic release with improved biocompatibility, while biomimetic systems, such as cell-membrane-, lipoprotein-, virus-, DNA-, and exosome-mimicking platforms, leverage natural transport and recognition pathways for tumor-specific targeting and immune evasion. Finally, we discuss translational considerations, including GMP-compatible manufacturing, batch consistency, long-term safety and immunogenicity, and advanced model selection, and outline future opportunities in high-throughput lipid discovery, AI-assisted ligand design, hydrogel-mediated spatiotemporal release, and patient-tailored nanotherapies. Collectively, these emerging nanocarriers offer a convergent strategy to navigate physiological barriers and advance precision nucleic-acid therapeutics against glioblastoma."

In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target."

While its cytoplasmic aggregation is the pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD), recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure. Under healthy conditions, TDP-43 forms dimers via its N-terminal domain, a configuration that is crucial for its nuclear solubility and cooperative RNA binding. In this review, we propose the \"Molecular Zipper\" hypothesis to describe the maintenance of TDP-43 structural homeostasis. In this framework, the N-terminal domain acts as a stabilizing \"NTD-mediated anchor\" that keeps the protein in a functional, \"zipped\" dimeric state, effectively sequestering its aggregation-prone C-terminal regions. Pathogenic triggers-including genetic mutations, aberrant post-translational modifications such as phosphorylation and acetylation, and environmental stressors-can \"unzip\" this structure, leading to the formation of pathogenic monomers. These pathogenic monomers show increased propensity for cytoplasmic mislocalization and recruit wild-type protein into aggregates through a prion-like seeded aggregation mechanism, culminating in nuclear functional loss and cytoplasmic gain-of-toxicity. We further evaluate the emerging diagnostic landscape, focusing on methods to monitor the dimer-to-monomer ratio. Integrating prior biochemical data on TDP-43 dimerization with structural modeling enables a more coherent account of the transition from the physiological dimer to pathological conformers. The Molecular Zipper framework offers a conceptual foundation for reconciling existing experimental findings and for guiding future studies on early structural changes in TDP-43 proteinopathy."

While both loss- and gain-of-function mechanisms contribute to disease, the discovery of cryptic splicing has shed light on the downstream consequences of TDP-43 nuclear clearance for neuronal health. Here, we highlight how loss of nuclear TDP-43 can drive a cascade of events that lead to the impairment of cellular proteostasis and result in a positive feedback loop that perpetuates neuronal dysfunction. This sustains the appearance of cryptic splicing events in genes that are involved in key pathways for the maintenance of axonal homeostasis and synaptic transmission. In contrast to their detrimental effects on neuronal health, cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies."

To decipher the underlying mechanisms responsible for these contradictions, we leverage emerging technologies that establish comprehensive cellular and spatiotemporal contexts for its signaling pathway. These approaches elucidate the mechanisms underlying central nervous system diseases and their potential therapeutic applications. In this review, we demonstrate how these advanced technologies enhance our understanding of the mechanism of activin A: CRISPR-based editing validates critical receptors such as ACVR1B in the process of remyelination; organoid and organ-on-a-chip systems model human-specific cellular interactions; spatial and single-cell multi-omics delineate expression and communication networks; and optogenetics/chemogenetics enable precise spatiotemporal control of signaling pathway activity. This technological toolkit provides a robust framework for elucidating the context-specific roles of activin A in conditions such as ischemic stroke, neurodegenerative diseases, glioma, epilepsy, and traumatic brain injury, encompassing key processes including neuroprotection, inflammation, and repair. Furthermore, these mechanistic insights inform next-generation interventions, including adeno-associated virus-mediated gene therapy for localized modulation and advanced nanodelivery systems for targeted biologic transport. Given these capabilities, artificial intelligence plays a crucial role in designing blood-brain barrier-permeable ligands and optimizing smart nanocarriers. By contrasting preclinical data with the clinical pipeline, which currently emphasizes peripheral diseases, we propose that integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement."

The existing therapies have only a small effect on alleviating symptoms, mainly because the therapeutic agents are difficult to cross the bloodbrain barrier. The purpose of the review is to discuss the potential of microneedle-based transdermal delivery systems to improve the delivery of drugs to the central nervous system and thereby manage neurodegenerative diseases effectively. The article summarizes and synthesizes the available literature that targets the strategies of microneedle-mediated drug delivery. The literature on the design, composition, pharmacokinetics, and mechanistic benefits of different microneedle platforms for surmounting central nervous system barriers was identified and thematically synthesized. Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier. Micro-needles can be used to deliver small molecules, peptides, and nanoparticles to the brain, thereby avoiding systemic side effects and enhancing drug bioavailability. Some of those designs include dissolving, coated, hollow, hydrogel-forming, and stimuli-responsive microneedles, which have been shown to target the brain and exhibit higher therapeutic efficiency in preclinical models. Although technological advances have improved, the clinical translation of microneedlebased strategies remains limited. The future directions could include using microneedles with stem cell-based therapies, CRISPR/Cas9 gene editing, artificial intelligence-based delivery systems, and responsive release technology to facilitate customized treatment. The Microneedle-based drug delivery systems are promising in overcoming the current limitations in the treatment of neurodegenerative diseases. Nonetheless, a large-scale clinical validation is necessary to guarantee safety, efficacy, and scalability to be applied to real-life scenarios."

However, current reviews often catalog virus-disease associations without integrating this evidence into a unified conceptual model that also accounts for the therapeutic potential of viral platforms. This review investigates recent literature to propose a \"dual-role\" model for viruses in NDDs. We analyze how diverse viruses (e.g., HSV-1, HIV, EBV, and SARS-CoV-2) converge on shared pathogenic pathways, including protein misfolding, chronic neuroinflammation, and mitochondrial dysfunction, across different NDDs. Paradoxically, engineered viral vectors derived from neurotropic viruses are being investigated as tools for targeted gene therapy. To address these therapeutic applications of viruses, this review also provides an in-depth report of the various viral vector technologies developed. The approaches involved in designing rationally engineered viral vectors based on various adeno-associated virus serotypes through rational design, directed evolution and machine learning strategies, as well as the lentiviral and herpes simplex virus-based platform are described. Different strategies that have been used to incorporate large and/or small payloads such as gene replacement, RNA interference, microRNA cassettes, CRISPR-based gene editing (base editing, prime editing, CRISPRa and CRISPRi) and the double AAV systems to deliver larger transgene cassette have also been reviewed. This review further includes various routes of administration including intrathecal, intracerebroventricular and convection-enhanced delivery with the use of Focused Ultrasound. The constraints imposed by the Blood-Brain Barrier are discussed, especially the approach using receptor-mediated transcytosis for crossing. The review also critically evaluates obstacles toward clinical translation of viral vectors due to various factors including immunogenicity, the presence of pre-existing neutralising antibodies and dose-dependent toxicity, illustrated by the fatal outcome of ASPIRO and DMD trials. Finally, this review concludes with other promising non-viral approaches such as lipid nanoparticle and extracellular vesicles. Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors."

Increasing evidence suggests that long non-coding RNAs (lncRNAs) play significant roles in neurodevelopment, neuronal homeostasis, and disease progression; however, their involvement in shared pathogenic pathways and clinical applications remains inadequately defined. This review consolidates recent experimental, transcriptomic, bioinformatic, and emerging clinical findings regarding the role of lncRNAs in NDDs. We examine how lncRNAs modulate common disease mechanisms, including protein misfolding and aggregation, neuroinflammation, mitochondrial dysfunction, ferroptosis, synaptic failure, and aging-related neurodegenerative processes. These regulatory functions occur through various mechanisms, including epigenetic modifications, transcriptional regulation, post-transcriptional processes, and RNA-protein interactions, as well as novel mechanisms such as liquid-liquid phase separation (LLPS), peptide coding, and exosome-mediated intercellular communication.\u00a0Current evidence supports the potential of lncRNAs as minimally invasive liquid biopsy biomarkers, detectable in blood, cerebrospinal fluid (CSF), and extracellular vesicles.

Already, much is known about therapeutic targets and how they would need to be manipulated to mitigate disease. For such gene therapies to move to the clinic, potent CNS delivery vehicles are needed. One line of investigation focuses on adeno-associated viruses (AAV) to address this need. In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration. This review will introduce this topic and provide an update on recent developments. First, we describe the physical barriers that must be overcome for AAV-delivered gene therapies to reach target cells in the CNS. We then put a spotlight on the natural AAV9 capsid's inherent propensity to cross the BBB and key lessons learned from its use for delivering a therapeutic payload for the treatment of spinal muscular atrophy. Next, we summarize methods for engineering recombinant AAV (rAAV) capsids with improved brain penetrance, and present in vitro paradigms for predicting their capacity to cross the human BBB. We also present strategies for side-stepping the delivery limitations of existing rAAV vectors. Finally, we point toward a few notable clinical studies whose outcomes may advance our understanding of what rAAV-delivered gene therapies can offer to people afflicted with CNS disorders."

This mutation is a potential target for CRISPR/Cas9-based genome editing. However, the blood-brain barrier and limitations of current viral or nanoparticle-based delivery systems to neurons significantly restrict the clinical application of CRISPR-Cas9 in the brain.

AELNs stably form complexes with ribonucleoproteins (RNPs) comprised of Cas9 proteins and guide RNAs (gRNAs). We improved the delivery efficiency and selectivity of AELN/RNP complexes in GLP2-receptor-expressing neurons by incorporating GLP2 peptides into the AELN/RNP complexes. Intranasal administration of peptide-tagged AELN/RNP complexes in vivo confirmed the successful genome editing of C9orf72, demonstrating the potential of this system for treating neurodegenerative diseases.

We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology.

Through CRISPR interference (CRISPRi) screening in human neurons, we identified the decapping scavenger enzyme (DCPS) as a novel genetic modifier of TDP-43 loss-of-function (LOF)-mediated neurotoxicity. Our findings reveal that TDP-43 LOF leads to aberrant mRNA degradation via dysregulating the properties and activity of processing bodies (P-bodies). TDP-43 interacts with P-body component proteins, potentially influencing their dynamic equilibrium and assembly into ribonucleoprotein (RNP) granules. Loss of TDP-43 hyperactivates P-bodies, increasing mRNA association and RNA decay. Reducing DCPS restores P-body integrity and RNA turnover, ultimately improving neuronal survival. Overall, this study highlights a novel role of TDP-43 in RNA processing through P-body regulation and identifies DCPS as a potential therapeutic target for TDP-43 proteinopathy-related neurodegenerative diseases."

As treatment for CNS disorders is primarily palliative, the underlying causes of disease progression are not addressed through conventional pharmacologic therapies. Gene therapy has the potential to address these root causes of disease progression; however, many of the vectors used in gene therapy (e.g., adeno-associated viruses (AAVs)) have limitations such as immunogenicity, low cargo capacity, and crossing the blood-brain barrier (BBB). These limitations have led to significant progress in the development of non-viral gene delivery systems.

Particular emphasis is placed on nanoparticle modification approaches to enhance BBB penetration and enable delivery of genome-editing technologies (CRISPR/Cas systems).

A key driver of this pathogenesis is nuclear loss of ALS-associated protein TDP-43, leading to mis-splicing of TDP-43 targets including important neuronal genes STMN2 and UNC13A . Here, we have developed a gene therapy strategy for ALS and related TDP-43 proteinopathies, to correct mis-splicing of both STMN2 and UNC13A cryptic exons using small nuclear RNAs (snRNAs) encoded from a single vector. We identified promoter sequence elements to increase therapeutic snRNA expression by 10-fold, then further optimized the expression cassette with combinatorial snRNA targeting to rescue multiple cryptic splicing targets. The engineered snRNAs restored normal pre-mRNA processing of both STMN2 and UNC13A transcripts despite TDP-43 loss of function, rescuing stathmin-2 protein levels in iPSC derived motor neurons, restoring their axonal regeneration capacity to wild-type levels. In addition, adeno-associated virus (AAV) delivery of the snRNAs to the murine central nervous system in the constitutive cryptic splicing model Stmn2 Hum\u0394GU fully restored cortical Stmn2 pre-mRNA processing, highlighting the utility of snRNAs as a therapeutic modality in vivo . Together, this study demonstrates that snRNAs are a promising and versatile therapeutic strategy for the simultaneous correction of multiple aberrant transcripts affected by cryptic splicing in TDP-43 proteinopathies."

"abstract_text": "ID: 42108387\nTitle: Rational Design and Optimisation of CRISPR-Cas9 Delivery Systems for Targeted Genomic Transformation.\nAbstract: The CRISPR-Cas9 genome-editing technique offers a promising therapeutic strategy for genetic disorders, including neurodegenerative diseases like Alzheimer's disease (AD), characterised by inherited susceptibility and progressive cognitive decline, as well as other hallmarks such as amyloid beta (A\u03b21-42) plaques and neurofibril tangles (NFTs). However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation. This comprehensive review compares various CRISPR-Cas9 delivery vectors, viral, nonviral and physical, with a focus on their efficacy in neurological diseases such as AD. Viral vectors viz., adeno-associated viruses (AAVs) and lentiviruses (LVs) demonstrate high transduction efficiency and BBB permeability. AAVs are preferred for their low immunogenicity, minimal toxicity, high neuronal tropism and episomal persistence, enabling sustained expression without insertional mutagenesis. LVs offer larger genetic payloads but raise concerns about genomic integration and potential oncogenesis, though integration-defective variants mitigate these risks. Nonviral vectors, including peptide and polymer-based nanoparticles, lipid nanoparticles (LNPs) and Inorganic carriers such as gold and silver nanoparticles, are less immunogenic and easier to handle but require further optimisation for in\u00a0vivo BBB crossing and endosomal escape. Physical methods such as electroporation and microinjection are suitable for in\u00a0vitro/ex vivo use, while novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis. These preclinical studies show that these technologies can successfully edit genes and provide therapeutic benefits, including amyloid reduction and cognitive improvement in AD models. Yet off-target effects, immune responses and regulatory hurdles persist. Overall, continuous innovation in delivery vector design and safety profile-targeting strategies is crucial for advancing CRISPR-Cas9 towards clinical therapies for AD-based therapies and related neurological disorders."

CHCHD2 and CHCHD10 mutations caused neurodegeneration in model animals as seen in patients, but their pathophysiological roles remain elusive. Here we reported a direct role of CHCHD2 and CHCHD10 in autophagy. We identified a protein complex composing of CHCHD2-CHCHD10-C1QBP/p32-Atg8-family proteins (ATG8s), in which each molecule interacted with another. CHCHD2, CHCHD10 and C1QBP/p32 associated with ATG8s, preferentially, GABARAPs. Disease-associated CHCHD2 and CHCHD10 mutations exhibited varied interaction with ATG8s. By binding to GABARAPs, CHCHD2 and CHCHD10 underwent autophagic degradation, and recruited the ULK1 complex. Autophagy initiation defects occurred upon transient knockdown of CHCHD2, and also in human iPSC-derived CHCHD2-/- or CHCHD2T61I dopaminergic neurons. Importantly, CHCHD2 and CHCHD10 promoted autophagy. CHCHD2 reduced protein aggregates in cells and toxic SNCA/\u03b1-synuclein species in mouse striatum.

Extracellular vesicles, particularly exosomes, that move bioactive substances between the stomach and the brain, such as proteins, lipids, metabolites, and microRNAs, may improve the gut-brain axis. In the past years, the role of exosome-mediated communication has been recognized as significant in relation to the etiology, continued progression, and potential treatment of neurodegenerative disorders. The authors of this review article present a summary of the current understanding of the relationship of gut microbiome, exosome biogenesis, and the pathophysiological development of neurodegenerative diseases. Evidence from laboratory studies, animal studies, and newly emerging human studies suggests that microbiome-based metabolites and inflammatory mediators may modulate how exosomes are produced, what they carry, and how they interact with the blood-brain barrier. These exosomal signals may impact neuroinflammation, neuronal signaling, and the spread of pathological proteins of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease. In addition, they examine some possible ways to target the gut-brain axis from a therapeutic perspective, including manipulating the gut microbiome, providing probiotics and/or prebiotics, performing fecal microbiota transplantation, and/or using engineered extracellular vesicles as vehicles for drug delivery.

This review summarizes advances (2022\u20132025) in lipid and biomimetic nanocarriers engineered to enhance nucleic-acid delivery for GBM therapy. For instance, ionizable lipid nanoparticles with pH-responsive chemistry and optimized head-group design achieve efficient cytosolic release with improved biocompatibility, while biomimetic systems, such as cell-membrane-, lipoprotein-, virus-, DNA-, and exosome-mimicking platforms, leverage natural transport and recognition pathways for tumor-specific targeting and immune evasion. Finally, we discuss translational considerations, including GMP-compatible manufacturing, batch consistency, long-term safety and immunogenicity, and advanced model selection, and outline future opportunities in high-throughput lipid discovery, AI-assisted ligand design, hydrogel-mediated spatiotemporal release, and patient-tailored nanotherapies.

Despite major advances in understanding its molecular basis, currently approved therapies remain largely symptomatic and fail to halt or reverse neurodegeneration, emphasizing the urgent need for disease-modifying strategies. In this comprehensive state-of-the-art review, we examine the rapidly evolving landscape of CRISPR-Cas9 and next-generation gene-editing technologies, including base editors and prime editors, as innovative therapeutic platforms for precisely modulating AD-associated genetic and molecular pathways. We discuss targeting of critical genes such as APOE4, APP, PSEN1, PSEN2, and MAPT, which play central roles in amyloid processing, tau pathology, lipid metabolism, and neuroinflammatory cascades, and evaluate strategies for allele-specific correction, gene silencing, and transcriptional regulation using CRISPR interference/activation and epigenome editing tools. The review further explores multiplex editing approaches that simultaneously target interconnected pathogenic networks underlying A\u03b2 accumulation, tau hyperphosphorylation, microglial activation, and synaptic dysfunction. A central focus is placed on overcoming delivery barriers to the central nervous system, particularly the blood-brain barrier (BBB), highlighting advances in engineered adeno-associated viral vectors, lentiviral systems, lipid nanoparticles, polymeric nanocarriers, exosome-based delivery, receptor-mediated transcytosis, immune-evasive vector design, and focused ultrasound-mediated BBB modulation.

Nuclear depletion and cytoplasmic aggregation of the RNA splicing protein TAR DNA-binding protein 43 (TDP-43) are observed in most ALS and FTD patients. Here we show that TDP-43 dysfunction causes mis-splicing of KCNQ2, which encodes a voltage-gated potassium channel (Kv7.2) that regulates neuronal excitability. Using iPSC-derived neurons and postmortem ALS/FTD brain and spinal cord tissue we find widespread, disease-specific and TDP-43-specific skipping of an exon encoding the KCNQ2 pore domain. The mis-spliced mRNA escapes degradation and is translated into a nonfunctional protein with severely reduced ion conductance that aggregates in the endoplasmic reticulum and causes intrinsic hyperexcitability in ALS neuronal models. This event, which correlates with higher phosphorylated TDP-43 levels and earlier age of disease onset in patients, can be rescued by splice-modulating antisense oligonucleotides that dampen hyperexcitability in induced pluripotent stem cell cortical neurons and spinal motor neurons with TDP-43 depletion. Our work reveals that nuclear TDP-43 maintains the fidelity of KCNQ2 expression and function and provides a mechanistic link between established excitability disruption in ALS/FTD patients and TDP-43 dysfunction."

A major feature of TDP-43 pathology is its nuclear depletion, leading to the aberrant inclusion of cryptic exons during RNA splicing. STMN2 and UNC13A have emerged as prominent TDP-43 splicing targets, but the broader impact of TDP-43-dependent cryptic splicing on neuronal function remains unclear. Here, we report previously unidentified TDP-43 splicing targets critical for membrane excitability and synaptic function, including KALRN, RAP1GAP, SYT7, and KCNQ2. Using human stem cell-derived neurons, we showed that TDP-43 reduction induces cryptic splicing and down-regulation of these genes, resulting in impaired excitability and synaptic transmission. In postmortem brains from patients with FTD, these cryptic splicing events occurred selectively in neurons with TDP-43 pathology. Suppressing individual cryptic splicing events using antisense oligonucleotides partially restored neuronal function, and combined targeting almost fully rescued the synaptic deficit caused by TDP-43 loss. Together, our findings provide evidence that cryptic splicing in these synaptic and membrane excitability genes is not only a downstream marker but instead a direct driver of neuronal dysfunction, establishing a mechanistic link between TDP-43 pathology and neurodegeneration in ALS and FTD."

In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target."

The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS."

However, current computational tools exhibit limited predictive capability beyond canonical GT-AG splice sites, making accurate assessment of noncanonical SAV pathogenicity a considerable challenge. To address this limitation, we developed MOSAIC (multimodal feature fusion for noncanonical splice-altering variants pathogenicity prediction), a deep learning framework designed for precise assessment of noncanonical SAV pathogenicity. MOSAIC integrates long-range contextual signals derived from a pretrained DNA language model, local sequence features captured from multi-scale convolutional neural networks, and functional annotations. By employing a transformer encoder and a gated fusion module, the model adaptively integrates these multimodal features. Benchmarking across multiple independent datasets demonstrated that MOSAIC consistently outperforms existing state-of-the-art methods, such as CADD and SpliceAI. It remains highly accurate and robust when evaluated on rare variants, gene-independent contexts, and the largest subset where all comparative methods yielded outputs. Furthermore, feature importance analysis revealed that long-range dependencies in DNA sequences and transformer-based integration were critical contributors to model performance. Interpretability analyses indicated that MOSAIC could identify key regulatory sequence motifs associated with transcription factors and RNA-binding proteins, offering mechanistic insight into how noncanonical SAVs disrupt splicing regulation and contribute to pathogenic processes. Overall, MOSAIC offers an accurate and interpretable framework for predicting the pathogenicity of noncanonical SAVs, thereby serving as a dependable computational tool for genetic diagnostics and precision medicine applications.

Although single-cell transcriptomics offers high-resolution profiling, translating these insights into clinical drug response prediction remains challenging. Recently, transfer learning approaches have attempted to predict patient drug response by leveraging pre-clinical data. However, these approaches operate at the bulk level, often masking the cellular heterogeneity essential for prediction. In this study, we propose scTAPE, a disentangled transfer learning framework to predict patient drug response using tumor single-cell transcriptomics. scTAPE follows a pre-training and fine-tuning paradigm. During the pre-training stage, scTAPE uses a disentangled learning strategy to extract intrinsic pharmacological signals masked by confounding factors from the matched bulk and single-cell expression profiles. Subsequently, a supervised drug response model is trained on labeled cell-line data to fine-tune the aligned common embedding, thereby achieving cross-domain generalization to unseen datasets. Experimental results demonstrate that scTAPE successfully predicts drug response across cell-line datasets and two independent clinical cohorts, outperforming state-of-the-art single-cell-based predictors. Furthermore, by analyzing tumor cell subpopulations, scTAPE not only predicts patient drug response to both single and combination treatments but also identifies potential therapeutic agents targeting drug-resistant subpopulations. The implementation of scTAPE is available via https://github.com/xinliangSun/scTAPE."

While open-source implementations have been published with author-reported comparisons, independent benchmarking across diverse datasets is needed to establish equivalence. We compared the original SpliceAI with two open-source implementations (OpenSpliceAI and CI-SpliceAI) and a legacy ensemble baseline across six datasets: a curated set of 1,316 validated variants, 213 variants with splice-assay data, 99,601 variants from the SPiP splicing prediction study, 242 manually curated deep intronic pathogenic variants, and two ClinVar-derived datasets comprising 53,600 intronic variants and 58,064 variants spanning all genomic contexts. The deep learning models were also evaluated against an ensemble of four legacy splice-prediction tools. Across all datasets, the deep learning algorithms outperformed the legacy ensemble. All three deep learning algorithms showed similar performance on the larger datasets dominated by canonical splice site variants (balanced accuracies 0.889-0.977). On the deep intronic benchmark, the original SpliceAI achieved the highest balanced accuracy (0.940), outperforming both CI-SpliceAI (0.890) and OpenSpliceAI (0.841). Critically, optimal thresholds for deep intronic variants were an order of magnitude lower than standard recommendations, indicating that default thresholds would miss the majority of pathogenic deep intronic variants. A correlation analysis showed that CI-SpliceAI maintained balanced concordance across event types, whereas OpenSpliceAI showed stronger correlation for loss events than gain events. Both implementations showed high positional agreement with SpliceAI, with exact splice-site match rates exceeding 90% across event types. Together, these results demonstrate that both open-source reimplementations of SpliceAI successfully reproduce the predictive behavior of the original algorithm across multiple evaluation contexts, while consistently outperforming traditional splice prediction methods. However, performance diverges on deeply intronic variants, and standard score thresholds are poorly calibrated for this variant class regardless of algorithm choice."

Here, to address this, we developed HELIX, a hierarchical deep learning framework that integrates pre-mRNA sequence and RNA-binding protein expression profiles to predict tissue- and condition-specific splicing patterns and transcript isoform usage simultaneously. By leveraging both short-read and long-read RNA sequencing data during training, HELIX achieves greater accuracy than existing splicing prediction models and conventional short-read-based methods in predicting differential splicing events, splicing strength at highly regulated splice sites, and isoform usage. The model enables systematic identification of tissue-specific splicing quantitative trait loci and their functional impacts. Furthermore, HELIX predicts patient-specific splicing dysregulation with quantitative attribution to genetic variants and abnormal RNA-binding protein expression in colon cancer cohorts. Through transfer learning, the HELIX model can be adapted to single-cell RNA sequencing data, thereby enabling the prediction of cell-type-specific isoforms."

Widespread usage of new technology that impacts the therapeutic process has outpaced an analysis of how that technology might affect the meaning and effectiveness of that process. Lawsuits assume such technology causes harm, while limited data and the literature has been more mixed. From Frankenstein to CRISPR, new technology always has its cheerleaders and its detractors. The more the technology seems to impact a topic especially connected to our humanity, the deeper the convictions will be on both sides. Certainly, when it comes to psychotherapy, the introduction of new technologies such as telepsychiatry to Therabots has provoked discussion. We argue that while new technologies offer practical advantages, they risk functioning as structural defenses against the vulnerability and authentic intimacy essential to transformative psychotherapy. Through analysis of the therapeutic alliance, relational dynamics, and the psychology of vulnerability, this paper contends that the structural form of telepsychiatry does not alter the inherent nature of the therapeutic experience, whereas AI-mediated therapy may collude with maladaptive defenses, fundamentally altering the nature of the therapeutic encounter."

In this work, we define how short, specific RNAs solubilize TDP-43. These short RNAs engage and stabilize the TDP-43 RNA recognition motifs, which allosterically destabilizes a conserved helical region in the prion-like domain, thereby promoting aggregation-resistant conformers. Sequence-space mining identified short RNA chaperones with enhanced activity against TDP-43 and disease-linked variants. Enhanced short RNA chaperones mitigated aberrant TDP-43 phenotypes in optogenetic models and in ALS patient-derived and control motor neurons. In mice with cytoplasmic TDP-43 aggregation and motor neuron loss, an enhanced short RNA chaperone reduced pathological aggregation, restored TDP-43 function, and conferred neuroprotection. These results define a mechanistic and therapeutic framework for RNA-based strategies to counter TDP-43 proteinopathies."

Its integration across the surgical pathway can improve clinical outcomes, efficiency, and patient safety. This narrative review provides an overview of the current and emerging applications of AI in SDM. A structured search of electronic databases was conducted using PubMed, Scopus, Web of Science, and Google Scholar. The search primarily focused on peer-reviewed publications from 2015 to 2025. AI applications include radiologic image analysis for preoperative planning, electronic health record mining for individualized surgical strategies, risk and immunological response prediction, and genomic analysis to guide treatment selection. Intraoperative, AI-based video, image, and physiological data processing can support real-time decision-making by improving precision, identifying anatomical targets, and predicting complications earlier. Postoperatively, AI systems can monitor patient data to detect complications, evaluate outcomes, and tailor follow-up therapy. Despite these advantages, challenges remain, including data quality and availability, model explainability, and others. Overcoming these barriers requires explainable and secure AI models, scalable infrastructures, clinician engagement, and robust regulatory frameworks.

It is unknown whether the analysis of routine laboratory tests and vitals using artificial intelligence presents a scalable and portable system for capturing the spectral nature of common diseases. We constructed and validated machine learning models targeting seven common diseases-atrial fibrillation, breast cancer, coronary artery disease, migraine, rheumatoid arthritis, schizophrenia, and type 2 diabetes-using routine clinical measurements from 394,957 electronic health records (EHRs) in the BioMe Biobank and UK Biobank. The Resulting model outputs, termed spectral health index from machine measurements of electronic records (SHIMMER), were assessed for association with disease diagnosis, risk factors, biomarkers, onset, survival, complications, and medications in two cohorts. SHIMMER was associated with disease diagnosis, known risk factors, and biomarkers in expected directions in both cohorts. With greater SHIMMER, the prevalence of risk factors, complications, and medications continuously increased; for instance, age and hypertension, stroke risk and cardiac arrest, and beta blockers increased, respectively, with atrial fibrillation SHIMMER. Biomarker levels for type 2 diabetes, such as glucose, hemoglobin A1c, C-reactive protein, and triglycerides, changed stepwise as SHIMMER increased. Rising SHIMMER also revealed gradations of earlier disease onset and decreased survival, particularly for coronary artery disease and schizophrenia. A holistic, non-invasive marker derived from machine learning trained on routine clinical measurements snapshots multiple common diseases on a spectrum, quantifying disease risk, severity, onset, survival, sequela, and treatment.

Increasing evidence suggests that dysregulation of these modifications contributes to cancer progression, immune evasion, therapeutic resistance, and metabolic disorders, suggesting their potential as therapeutic targets. This review summarizes recent advances in endogenous epitranscriptomic RNA modifications and discusses their relevance in cancer immunotherapy and metabolic diseases. In addition, emerging therapeutic approaches targeting RNA-modifying enzymes, including writers, erasers, and readers, are discussed along with the development of antisense oligonucleotides, RNA-based therapeutics, and delivery systems. Recent progress in lipid nanoparticles, polymeric carriers, and targeted delivery platforms has improved the stability, specificity, and translational potential of RNA-targeted therapies.

The literature underscores that these technologies, when combined with non-viral delivery platforms, provide a roadmap for early-stage (presymptomatic) therapeutic intervention in ALS.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe synthesis of high-throughput multi-omics data, including single-cell transcriptomics and AI-driven structural modeling, provides a quantitative basis for identifying TDP-43-dependent cryptic splicing in motor neurons. Integrating these diagnostic insights with advanced delivery vectors (lipid nanoparticles, engineered exosomes) allows for the targeted, brain-penetrant correction of pathogenic molecular programs before significant neurodegeneration ensues.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm shift in treating amyotrophic lateral sclerosis (ALS) relies on identifying the convergence of genomic instability and RNA metabolism. TDP-43, an RNA-binding protein, regulates splicing to repress non-conserved cryptic exons. Loss of nuclear TDP-43 leads to the upregulation of these cryptic exons, serving as a sensitive diagnostic biomarker. Recent advances show that \"Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction.\" This diagnostic precision facilitates targeting: \"Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity.\" \n\nThe challenge of neurotoxicity is addressed by identifying these events presymptomatically, as \"This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation.\" To enable treatment, \"non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration.\" Furthermore, AI/computational approaches are optimizing these systems, as \"The findings show a shift from basic vesicle characterisation toward engineered delivery systems, CNS disease applications, and translational evaluation.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Cryptic splicing in genes like *STMN2* is a direct driver of neuronal dysfunction, not merely a downstream marker.\n* PDI-mediated pathways offer a therapeutic target for disassembling pathogenic TDP-43 condensates.\n* Single-cell Raman spectroscopy serves as a label-free prognostic tool for metabolic status in disease models.\n* Non-viral nanocarriers can be functionally modified with peptides to achieve receptor-mediated transcytosis across the BBB.\n* Early intervention is feasible because transport deficits and molecular signatures often precede clinical motor neuron loss.\n* cGAS-mediated innate immune signaling acts as an upstream modulator of TDP-43-driven splicing errors.\n* Inhibiting kinases like SGK1 can improve microglial phagocytosis and debris clearance in ALS models.\n* Biomimetic nanoplatforms derived from neural stem cells can be used for precise, site-specific therapeutic delivery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The provided literature confirms that AI-integrated frameworks are actively being developed to resolve transcriptomic heterogeneity and identify biomarkers of TDP-43 dysfunction. Single-cell RNA sequencing (scRNA-seq) and associated computational pipelines are established tools for mapping cryptic splicing events\u2014such as those in *STMN2* and *UNC13A*\u2014that drive neuronal dysfunction in amyotrophic lateral sclerosis (ALS). Furthermore, the literature explicitly supports the development of BBB-penetrant CRISPR systems to target genetic drivers of neurodegeneration, though clinical implementation remains a challenge requiring ongoing innovation in delivery vector design and safety protocols.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe convergence of AI, spatial transcriptomics, and CRISPR technology offers a comprehensive paradigm for addressing TDP-43 proteinopathy. By mapping the full-length transcriptomic landscape of neurons harboring TDP-43-dependent cryptic exons, researchers can refine precise therapeutic interventions. Integrating these insights with advanced BBB-crossing nanocarriers and CRISPR systems provides a potential roadmap for preemptive, personalized gene editing.\n\n### [INTRODUCTION & JUSTIFICATION]\nTDP-43 pathology, characterized by nuclear depletion and cytoplasmic aggregation, serves as the primary driver of RNA splicing failure in ALS. The literature demonstrates that \"TDP-43 dysfunction causes mis-splicing of KCNQ2, which encodes a voltage-gated potassium channel (Kv7.2) that regulates neuronal excitability.\" This mis-splicing event is not a passive consequence but a \"direct driver of neuronal dysfunction,\" establishing a mechanistic link between TDP-43 pathology and disease onset. Advanced AI methodologies, including hierarchical transformers and graph-based models, enable \"capturing subtle sequence patterns and contextual dependencies\" to predict these splicing disruptions with high accuracy. When paired with \"biomimetic nanoparticles\" or \"focused ultrasound-mediated\" BBB opening, these CRISPR-based strategies hold \"transformative potential\" for addressing the \"root genetic causes\" of neurodegeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **Cryptic Exon Stability:** Abberant transcripts resulting from TDP-43-dependent cryptic splicing often \"escape nonsense-mediated decay and are translated into truncated peptides,\" which act as stable, neurotoxic polypeptides.\n* **Transcriptional Snapshots:** Technologies like \"IsoRefiner\" leverage long-read RNA-seq to define full-length structures of cryptic-exon-containing transcripts, which are otherwise invisible in short-read datasets.\n* **Protein-Disulfide Interaction:** PDI (Protein Disulfide Isomerase) acts as a chaperone that \"antagonizes TDP-43 pathological aggregates\" by disassembling TDP-43/G3BP1 condensates.\n* **S-Acylation Regulation:** Reduced S-acylation of TDP-43 promotes aggregation, suggesting that lipid modifications represent an overlooked regulatory layer for stabilizing TDP-43.\n* **Microbial/Viral Intersection:** Air pollutants like toluene may interact with interferon-related immune proteins, suggesting potential environmental triggers for TB that intersect with known neuroinflammatory signaling pathways.\n* **AI-Histopathology:** Deep convolutional neural networks can detect \"learnable tissue morphologies\" from routine histopathology (e.g., fibrosis or inflammation) that correlate with specific genetic genotypes (e.g., Nurr1 haplo-insufficiency).\n* **Multi-branch Transformer Fusion:** Models such as CRISPR-MBTF utilize attention mechanisms to model complex biological contexts, outperforming traditional heuristic scoring for off-target prediction.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"finalResponse": "Amyotrophic lateral sclerosis (ALS) is a devastating condition often linked to a protein called TDP-43, which normally helps manage our cells' genetic instructions. In patients with ALS, this protein stops working correctly, leading to \"cryptic splicing errors\"\u2014think of these as typos in the cell's internal blueprints that cause vital parts of the body to malfunction.\n\nScientists are now using three main tools to tackle this:\n\n1. **Mapping with AI and Genetics:** By using \"single-cell RNA sequencing,\" researchers can look at individual cells in the brain to see exactly where these \"typos\" are happening. AI acts as a super-powered filter, allowing scientists to spot patterns in this massive amount of data that a human could never see on their own.\n2. **Precision Repair (CRISPR):** Once they find the exact location of a genetic \"typo,\" scientists are working on CRISPR\u2014a tool that acts like a pair of molecular scissors\u2014to cut out or fix the error, essentially editing the blueprint back to normal.\n3. **Getting Past the Guardrail:** The brain has a natural filter called the Blood-Brain Barrier (BBB) that usually blocks most medicines. Researchers are currently developing tiny, engineered \"delivery vehicles\"\u2014such as special nanoparticles\u2014that act like a key to bypass this filter, ensuring the repair tools reach the damaged neurons directly.\n\nIn short, the goal is to catch these genetic errors early, use AI to identify the specific damage, and then use advanced delivery technology to send \"repair kits\" into the brain before the neurons stop working.",

Integrating these diagnostic insights with advanced delivery vectors (lipid nanoparticles, engineered exosomes) allows for the targeted, brain-penetrant correction of pathogenic molecular programs before significant neurodegeneration ensues.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm shift in treating amyotrophic lateral sclerosis (ALS) relies on identifying the convergence of genomic instability and RNA metabolism. TDP-43, an RNA-binding protein, regulates splicing to repress non-conserved cryptic exons. Loss of nuclear TDP-43 leads to the upregulation of these cryptic exons, serving as a sensitive diagnostic biomarker. Recent advances show that \"Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction.\" This diagnostic precision facilitates targeting: \"Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity.\" \n\nThe challenge of neurotoxicity is addressed by identifying these events presymptomatically, as \"This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation.\" To enable treatment, \"non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration.\" Furthermore, AI/computational approaches are optimizing these systems, as \"The findings show a shift from basic vesicle characterisation toward engineered delivery systems, CNS disease applications, and translational evaluation.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Cryptic splicing in genes like *STMN2* is a direct driver of neuronal dysfunction, not merely a downstream marker.\n* PDI-mediated pathways offer a therapeutic target for disassembling pathogenic TDP-43 condensates.\n* Single-cell Raman spectroscopy serves as a label-free prognostic tool for metabolic status in disease models.\n* Non-viral nanocarriers can be functionally modified with peptides to achieve receptor-mediated transcytosis across the BBB.\n* Early intervention is feasible because transport deficits and molecular signatures often precede clinical motor neuron loss.\n* cGAS-mediated innate immune signaling acts as an upstream modulator of TDP-43-driven splicing errors.\n* Inhibiting kinases like SGK1 can improve microglial phagocytosis and debris clearance in ALS models.\n* Biomimetic nanoplatforms derived from neural stem cells can be used for precise, site-specific therapeutic delivery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The provided literature confirms that AI-integrated frameworks are actively being developed to resolve transcriptomic heterogeneity and identify biomarkers of TDP-43 dysfunction. Single-cell RNA sequencing (scRNA-seq) and associated computational pipelines are established tools for mapping cryptic splicing events\u2014such as those in *STMN2* and *UNC13A*\u2014that drive neuronal dysfunction in amyotrophic lateral sclerosis (ALS). Furthermore, the literature explicitly supports the development of BBB-penetrant CRISPR systems to target genetic drivers of neurodegeneration, though clinical implementation remains a challenge requiring ongoing innovation in delivery vector design and safety protocols.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe convergence of AI, spatial transcriptomics, and CRISPR technology offers a comprehensive paradigm for addressing TDP-43 proteinopathy. By mapping the full-length transcriptomic landscape of neurons harboring TDP-43-dependent cryptic exons, researchers can refine precise therapeutic interventions. Integrating these insights with advanced BBB-crossing nanocarriers and CRISPR systems provides a potential roadmap for preemptive, personalized gene editing.\n\n### [INTRODUCTION & JUSTIFICATION]\nTDP-43 pathology, characterized by nuclear depletion and cytoplasmic aggregation, serves as the primary driver of RNA splicing failure in ALS. The literature demonstrates that \"TDP-43 dysfunction causes mis-splicing of KCNQ2, which encodes a voltage-gated potassium channel (Kv7.2) that regulates neuronal excitability.\" This mis-splicing event is not a passive consequence but a \"direct driver of neuronal dysfunction,\" establishing a mechanistic link between TDP-43 pathology and disease onset. Advanced AI methodologies, including hierarchical transformers and graph-based models, enable \"capturing subtle sequence patterns and contextual dependencies\" to predict these splicing disruptions with high accuracy. When paired with \"biomimetic nanoparticles\" or \"focused ultrasound-mediated\" BBB opening, these CRISPR-based strategies hold \"transformative potential\" for addressing the \"root genetic causes\" of neurodegeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **Cryptic Exon Stability:** Abberant transcripts resulting from TDP-43-dependent cryptic splicing often \"escape nonsense-mediated decay and are translated into truncated peptides,\" which act as stable, neurotoxic polypeptides.\n* **Transcriptional Snapshots:** Technologies like \"IsoRefiner\" leverage long-read RNA-seq to define full-length structures of cryptic-exon-containing transcripts, which are otherwise invisible in short-read datasets.\n* **Protein-Disulfide Interaction:** PDI (Protein Disulfide Isomerase) acts as a chaperone that \"antagonizes TDP-43 pathological aggregates\" by disassembling TDP-43/G3BP1 condensates.\n* **S-Acylation Regulation:** Reduced S-acylation of TDP-43 promotes aggregation, suggesting that lipid modifications represent an overlooked regulatory layer for stabilizing TDP-43.\n* **Microbial/Viral Intersection:** Air pollutants like toluene may interact with interferon-related immune proteins, suggesting potential environmental triggers for TB that intersect with known neuroinflammatory signaling pathways.\n* **AI-Histopathology:** Deep convolutional neural networks can detect \"learnable tissue morphologies\" from routine histopathology (e.g., fibrosis or inflammation) that correlate with specific genetic genotypes (e.g., Nurr1 haplo-insufficiency).\n* **Multi-branch Transformer Fusion:** Models such as CRISPR-MBTF utilize attention mechanisms to model complex biological contexts, outperforming traditional heuristic scoring for off-target prediction.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In this review, we examine the structure and regulation of TDP-43, how these features influence its localization and functional activity, and how their disruption may contribute to disease. Among TDP-43's diverse functions, splicing repression of nonconserved RNA sequences termed cryptic exons has emerged as especially central to human disease. TDP-43 nuclear depletion and cytoplasmic aggregation are well-established pathological features in affected neurons and glia of neurodegenerative diseases, and accumulating evidence suggests that loss of TDP-43-mediated splicing repression occurs presymptomatically in disease. Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction. Here, we synthesize current knowledge of TDP-43 biology and curate datasets from human tissues and experimental models, focusing on cryptic splicing to provide a resource for leveraging cryptic exon biology to better understand, detect, and target TDP-43 dysfunction."

This narrative critical review is explicitly scoped to AD and PD, the only neurodegenerative conditions for which postmortem detection of gingipains in affected brain regions, mechanistic evidence from cellular and animal models, and clinical epidemiological data currently exist in sufficient depth to support an integrated synthesis. Robust meta-analyses confirm that periodontitis is associated with elevated AD/PD risk (OR/HR 1.2-3.5), while gingipains have been detected in a high proportion (>85-90%) of postmortem AD/PD brains, correlating with tau/\u03b1-synuclein pathology, neuroinflammation, and neuronal loss. Mechanistic studies in cellular and animal models demonstrate that gingipains can disrupt blood-brain barrier integrity via tight-junction cleavage, trigger NF-\u03baB/NLRP3-driven glial activation, catalyse amyloid-\u03b2/\u03b1-synuclein seeding, induce tau truncation/hyperphosphorylation, and precipitate mitochondrial oxidative damage, thereby generating self-amplifying neurotoxic cascades. Salivary gingipain activity offers a non-invasive, high-sensitivity biomarker candidate for early risk stratification that may outperform conventional fluid markers in prodromal cohorts. Therapeutically, small-molecule gingipain inhibitors have shown neuroprotective effects in preclinical models (e.g., atuzaginstat/COR388 failed primary endpoints in the Phase 2/3 GAIN trial but demonstrated subgroup benefits in P. gingivalis-positive participants; the next-generation inhibitor LHP588 is advancing in the Phase 2 SPRING trial). Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity. This review provides an integrated, isoform-resolved framework linking gingipain structure-function to neurodegeneration. While associative and mechanistic evidence is compelling, definitive causation in humans and disease-modifying efficacy require further validation through biomarker-guided clinical trials. Precision inhibition of gingipains represents a promising upstream strategy for addressing a potentially modifiable microbial contributor at the oral-brain interface."

Despite marked genetic and pathological heterogeneity, a unifying pathogenic framework remains lacking. We propose that axonal transport impairment represents an early and convergent but genotype-modulated upstream vulnerability in ALS, contributing to distal synaptic failure, bioenergetic stress, protein aggregation, neuroinflammation, and neuronal death. Across many ALS models, including SOD1, TARDBP (TDP-43), FUS, and C9orf72, transport deficits are frequently detectable in presymptomatic stages, often preceding overt motor neuron loss or clinical manifestation, although temporal ordering varies by molecular subtype. Human data from induced pluripotent stem cell-derived motor neurons and neuroimaging in mutation carriers further support early transport dysfunction in both familial and sporadic ALS. We synthesize genetic, cellular, and systems-level evidence demonstrating that diverse ALS-associated mutations converge on intracellular trafficking machinery through distinct but interacting mechanisms, disrupting long-range cargo delivery and clearance in motor neurons. This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation. This model generates testable predictions regarding presymptomatic transport biomarkers and the timing of therapeutic intervention. We discuss implications for biomarker development and therapeutic strategy, proposing restoration of axonal transport as a central component of rational multimodal disease modification in ALS."

As treatment for CNS disorders is primarily palliative, the underlying causes of disease progression are not addressed through conventional pharmacologic therapies. Gene therapy has the potential to address these root causes of disease progression; however, many of the vectors used in gene therapy (e.g., adeno-associated viruses (AAVs)) have limitations such as immunogenicity, low cargo capacity, and crossing the blood-brain barrier (BBB). These limitations have led to significant progress in the development of non-viral gene delivery systems. Compared with viral vectors, non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration. This review reports recent advancements in the development of non-viral platforms for CNS gene delivery and focuses on lipid-based nanoparticles, polymeric nanoparticles, exosome-based techniques, and new hybrid technologies. Particular emphasis is placed on nanoparticle modification approaches to enhance BBB penetration and enable delivery of genome-editing technologies (CRISPR/Cas systems). The review provides explanations of clinical trials, regulatory considerations, and manufacturing issues that result from the recent developments noted above. It also explores the emerging role of artificial intelligence in supporting carrier design and enhancing delivery efficiency. Both artificial intelligence and non-viral platforms have the potential to facilitate the advancement of safe, effective, and repeatably administered gene therapies for patients with CNS disorders."

Although liposomes and polymeric nanoparticles have improved brain drug delivery, limitations remain in BBB targeting, long-term biocompatibility, and in vivo clearance. Exosomes are endogenous nanoscale extracellular vesicles with favourable biocompatibility, low immunogenicity, and BBB-crossing potential. Therefore, this bibliometric study summarises the current research status, future research trends, and challenges in the more specific field of exosome-mediated BBB drug delivery. A comprehensive search was conducted across the Web of Science Core Collection (WoSCC), PubMed, and Embase databases for relevant English-language literature on exosome-mediated drug delivery across the blood-brain barrier from 2015 to 2025. WoSCC served as the primary source for bibliometric analysis. PubMed and Embase databases were used for supplementary validation. Software such as VOSviewer, CiteSpace, and R-bibliometrix was employed for literature visualisation analysis. This study included 1,365 relevant articles from the WoSCC database, and the annual publication volume showed a steady upward trend. China and the United States significantly lead in both the number of publications and the number of core contributing institutions in this field. Co-occurrence analysis of keywords showed that research hotspots are mainly focused on exosomes, the blood-brain barrier, drug delivery, and Alzheimer's disease. PubMed and Embase were used as supplementary validation databases, including 1,089 and 1,517 records, respectively. Their annual publication trends, major countries/regions, core journals, and keywords/themes were generally consistent with WoSCC, supporting the macro-level stability of the bibliometric findings. Unlike previous bibliometric analyses that mainly focused on overall trends in CNS exosome research, this study focuses specifically on the direction of exosome-mediated drug delivery across the BBB. The findings show a shift from basic vesicle characterisation toward engineered delivery systems, CNS disease applications, and translational evaluation. Mammalian-derived exosomes remain dominant, while plant-derived vesicles, AI-assisted design, biomimetic hybrid nanovesicles, and gut-brain axis strategies are emerging areas of focus. Future research should prioritise systematic platform comparisons, standardised evaluation, quality control, scalable production, long-term safety, and regulatory pathways."

We previously reported that cellular stress can lead to STMN2 loss due to TDP-43 nuclear condensation. Here, using human and murine neuronal cell models, multiple pharmacological tools, in situ single-molecule analysis of translation and RNA localisation, and longitudinal analysis of neuronal fitness/survival, we establish TDP-43-independent mechanisms of STMN2 depletion under stress. We find that human STMN2 protein level is extremely labile under acute high-magnitude stress. Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing. We further show that STMN2 protein level is highly sensitive to chronic translation deficits, such as those elicited by prolonged low-grade stress. We find that low pre-stress STMN2 sensitises neuronal cells to stress-induced apoptosis, whereas moderately increased STMN2 is protective under stress. Finally, we demonstrate that STMN2 mRNA is upregulated in non-TDP ALS (ALS-FUS) models, which may compensate for translation/stress granule defects in this disease subtype. Consistent with the compensation hypothesis, STMN2 mRNA is also upregulated in the relatively spared (cortex), but not severely affected (spinal cord), CNS regions in ALS-TDP. In conclusion, our study implicates two common denominators in neurodegeneration - dysregulation of translation and stress granules - in STMN2 depletion, independent of TDP-43 loss of function. It also describes an RNA-based compensatory mechanism in ALS underling the unique vulnerability of neurons with developing TDP-43 pathology."

In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target."

However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models."

We have previously demonstrated the role of symmetrical dimethylation (me2s) of a conserved arginine residue (R1810 in human POLR2A) in the C-terminal domain (CTD) of RNA polymerase II (RNAPII), which facilitates the recruitment of the Tudor domain-containing protein SMN to resolve R-loops at transcriptional termination sites. Here, we demonstrate that TDP-43 and FUS contribute to transcription termination through the R1810me2s-SMN pathway. Our data show that TDP-43-and to a lesser extent, FUS-are recruited to chromatin via this pathway, and that disruption of their recruitment leads to defective RNAPII termination. This impairment results in the accumulation of R-loops and elevated DNA damage to gene terminators. Using transcriptome-wide analyses, we further show that TDP-43 RNA-binding sites are highly correlated with regions of R-loop formation. Importantly, we find that the RNA-binding activity of TDP-43 is essential for its role in resolving R-loops and promoting efficient transcription termination. These findings establish a mechanistic link between TDP-43/FUS, R-loop resolution, and transcription termination, providing new insights into how their dysfunction may drive genome instability and contribute to the pathogenesis of ALS and FTD."

Although neuroinflammation is increasingly recognized as a hallmark of ALS, the precise molecular programs linking immune responses to MN pathology remain poorly defined. Using an integrated approach that combines single-cell and bulk RNA sequencing with spatial proteogenomics, we characterized both shared and distinct immune dynamics in peripheral blood and spinal cord tissues from patients with sporadic ALS and those carrying C9orf72 repeat expansions. Our analysis revealed broad immune remodeling in C9orf72 ALS, ALS subtype-specific and progression-associated differences in monocyte activation and antigen-experienced CD8 effector memory T cells with clonal features consistent with antigen-driven responses. Spatial mapping revealed complement activation and lipid-programmed myeloid states converging at sites of MN loss and TDP-43 pathology. Together, these findings connect peripheral and central immune alterations to ALS heterogeneity and highlight stratified immunomodulation as a potential therapeutic strategy."

We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology."

While conventional platforms such as liposomes, polymeric nanoparticles, and viral vectors often suffer from immune clearance and poor brain accumulation, engineered exosomes leverage natural cellular transport mechanisms to cross the BBB, protect cargo from degradation, and enable biocompatible interactions with target cells. This review takes a mechanistic and translational look at how exosomes are being engineered for CNS disorders, with a particular focus on glioblastoma. We cover exosome biogenesis through ESCRT-dependent and ESCRT-independent pathways, and how the competition between Rab27-driven secretion and Rab7-driven lysosomal degradation determines how many exosomes a cell releases, which has direct consequences for therapeutic production. We then discuss cargo loading strategies, from genetic approaches where donor cells are engineered to package specific molecules during biogenesis to physical methods like electroporation and sonication applied to isolated vesicles, alongside surface modification techniques for directing exosomes toward specific cell types. In glioblastoma, engineered exosomes have shown real promise for delivering chemotherapeutics across the BBB, targeting glioma stem cells, enabling CRISPR-based gene editing, and functioning as combined treatment and imaging tools. Applications in stroke and neurodegenerative diseases, where engineered exosomes carrying microRNAs and neuroprotective cargo have produced encouraging preclinical results, are also discussed. Scalable manufacturing and consistent targeting remain the hardest unsolved problems, and we outline emerging approaches including bioreactor-based production, programmable cargo loading, and patient-specific exosome design that are beginning to address these gaps. Overall, the progress reviewed here suggests that engineered exosomes are moving from an interesting biological concept toward a practically viable platform for CNS drug delivery."

Because motor output combines fast and slow muscle fibers with distinct kinetics, prolonged slow-fiber activation can broaden burst envelopes and blur within-cycle transitions, limiting temporal precision. Here, we show that agility training improves locomotor timing by selectively compressing the activity of slow motor neurons through enhancing commissural inhibition. In adult zebrafish, training increased locomotor stability and reshaped cycle structure in vivo, shortening the contraction phase while extending relaxation. Ex vivo motor-nerve recordings revealed sharper burst envelopes and reduced temporal dispersion after training, explained by a selective narrowing of slow, but not fast, motor neuron discharge within each cycle. Training enhanced phase-locked commissural inhibition during locomotion, consistent with an inhibitory gate aligned to burst offset. Finally, electrophysiology and single-cell transcriptomics associated this plasticity with increased glycinergic receptor expression in slow motor neurons. Together, our findings identify a circuit and a molecular substrate for training-induced gains in agility and suggest that motor precision can be improved by inhibitory reformatting of slow motor output rather than by uniformly increasing excitation."

Accumulation of DNA damage is emerging as a novel correlative trait of ALS. We recently showed that formation of TDP-43 and FUS cytoplasmic inclusions (CIs) lead to DNA damage accumulation through dysregulation of the DNA damage response (DDR). However, the multiple molecular mechanisms contributing to DNA damage accumulation in affected motor neurons in ALS have not been fully elucidated. In recent years, chemical inhibition of the serine/threonine kinase CHK1 was shown to lead to accumulation of DNA breaks as well as increased apoptosis, in differentiated cortical neurons. Notably, CHK1 has been involved in DNA double-strand break repair in non-dividing cells, by acting through the histone chaperone ASF1A. In this article, we show that cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A. We observe CHK1 protein downregulation in neuronal cell lines, as well as in patient-derived motor neurons progenitors and in the spinal cord of a FUS-ALS mouse model. Restoration of the nuclear levels of CHK1 and ASF1A via transient overexpression, is sufficient to reduce DNA damage signal accumulation and rescues DDR defects. Importantly, we show that the ubiquitin-proteasome pathway is responsible for CHK1 degradation in cells bearing FUS CI, since its inhibition restores CHK1 and ASF1A protein levels. Our study demonstrates that proteasomal-dependent CHK1 and ASF1A downregulation contributes to accumulation of DNA damage in cells affected by ALS-linked protein aggregates."

We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology. We discuss the implications of a dynamic equilibrium of folded and unfolded rG4s in health and disease, with particular focus on their emerging roles in neurodegeneration."

Although its treatment strategy has gradually developed from traditional chemotherapy to a multimodal treatment system including novel targeted therapy and immunotherapy, primary drug resistance in particular remains the core clinical problem leading to poor patient prognosis. This clinical dilemma indicates that the traditional genotyping system based on genomics has not been able to fully resolve the molecular heterogeneity of acute myeloid leukemia (AML), and it is urgent to establish a precise stratified model that can dynamically reflect the functional status of tumor cells in the initial stage of treatment. In this study, Raman spectroscopy (RS) combined with machine learning algorithm was used to construct a metabolic prognosis prediction model for AML chemotherapy response. Bone marrow single cell Raman spectroscopy data of newly diagnosed AML patients were collected, and the molecular fingerprint was analyzed by principal component analysis linear discriminant analysis (PCA-LDA) and multivariate curve resolute alternating least square method (MCR-ALS). The results showed that the PCALDA model achieved complete remission or non-remission (CR/NR) classification through 24 principal components (cumulative variance contribution of 90.1%), the accuracy of external validation was 94.8% (sensitivity 97.9%, specificity 92.0%), and the AUC reached 96.27%. Protein, lipid, nucleic acid and mixed components were decomposed by MCR-ALS, and lipid and nucleic acid metabolic pathways were enriched in NR group (P < 0.001). Studies have shown that RS single-cell metabolic fingerprint can decode the metabolic reprogramming features associated with chemotherapy resistance in AML, providing a new marker-free and highly sensitive tool for real-time prognostic stratification and targeted intervention."

To address these challenges, we developed folic acid-targeted PLGA-zein hybrid core-shell nanoparticles for the codelivery of the alkylating agent TMZ and the natural PARP inhibitor Ellagic acid (FA-TMZ/EA-PZ-CS NPs), thereby enabling simultaneous enhancement of drug delivery and suppression of chemoresistance pathways. Methods and Results: The dual-drug nanoplatform was fabricated using a double-emulsion solvent evaporation method and functionalized via EDC/NHS-mediated folic acid conjugation to promote receptor-mediated uptake. Physicochemical characterisation confirmed uniform spherical morphology, high colloidal stability, efficient drug encapsulation, and sustained biphasic drug release consistent with a core-shell diffusion mechanism. In LN229 glioblastoma cells, folic acid conjugation significantly enhanced cellular internalisation and cytotoxic efficacy compared to free drugs and non-targeted nanoparticles. Combination index analysis revealed strong synergism between TMZ and ellagic acid, resulting in markedly reduced IC50 values. Mechanistic studies demonstrated apoptosis induction, increased DNA damage, inhibition of cell migration at sub-cytotoxic concentrations, and downregulation of PARP gene expression. Conclusion: Overall, this study establishes a targeted core-shell nanotherapeutic strategy that integrates chemotherapy with DNA repair inhibition to overcome TMZ resistance, offering a mechanistically sound strategy that serves as a foundational framework for future translational research."

Through immunofluorescent labelling and single-cell RNA sequencing analyses of these lumbar spinal cord organoids, we identified an enriched neuronal population complemented by a diverse array of glial subtypes that successfully recapitulate the ventral spinal cord, demonstrating greater anatomical relevance than conventional 2D motor neuron cultures. Notably, these organoids displayed functional neuronal properties, including spontaneous activity, indicative of integrated neural networks.

Until recently, only symptomatic management was available. This review provides pediatric neurologists with a comprehensive, practice-oriented overview of emerging disease-modifying therapies for AS, focusing on therapeutic approaches advancing through clinical development. The molecular pathophysiology of AS, natural history considerations critical for trial interpretation, and the current evidence for antisense oligonucleotide (ASO) therapies (ION582, GTX-102/apazunersen, rugonersen), gene replacement approaches (MVX-220), and next-generation strategies including CRISPR-based gene editing, artificial transcription factors, small molecules, and novel delivery platforms are reviewed. ASO therapies targeting the UBE3A antisense transcript represent the most clinically advanced approach, with three candidates showing proof-of-concept efficacy in Phase 1/2 studies and two advancing to pivotal Phase 3 trials. Gene replacement therapy offers potential single-administration treatment but faces challenges regarding safety, immune responses, and durability. Next-generation approaches including CRISPR activation, epigenetic editing, and blood-brain barrier-penetrating delivery systems show preclinical promise. Critical challenges include outcome measurement limitations, genotype stratification, long-term safety monitoring, and ensuring equitable access. These advances herald a transformation in AS clinical care and represent a milestone in precision pediatric neurology."

"abstract_text": "ID: 42357281\nTitle: Tjap1/Pilt Is a cis-Golgi-Associated Protein Required for Golgi Integrity and Normal Drug Transporter Expression in Brain Microvascular Endothelial Cells In Vitro.\nAbstract: Background: Brain microvascular endothelial cells (BMECs) form the blood-brain barrier (BBB), a highly selective interface that restricts paracellular diffusion and regulates the transport of nutrients and drugs into the central nervous system via specialized transporters and receptors. Tight junction-associated protein 1 (Tjap1), also termed protein incorporated later into tight junctions (Pilt), has been localized to tight junctions (TJs) in epithelial cells and to the trans-Golgi network in fibroblasts; however, its expression, subcellular localization, and functional significance in BMECs are still unknown. Methods: We characterized Tjap1 subcellular localization in mouse and human BMEC cell lines as well as primary mouse BMECs by immunofluorescence with and without pharmacological Golgi disruption by treatment with Brefeldin A, Golgicide A or Pitstop 2. CRISPR/Cas9-mediated Tjap1 knockout cells were generated and examined with regard to their Golgi morphology using immunostaining. Tjap1 mRNA localization was examined by RNAscope in situ hybridization. Quantitative real-time PCR and Western blot was performed to assess the expression of BBB-associated efflux transporters, solute carrier transporters, and cellular receptors in control and Tjap1 knockout cells. Results: Tjap1 predominantly localized to the cis-Golgi compartment, co-localizing with Gm130 rather than Tgn38, and was absent from TJs in BMECs. Tjap1 knockout induced pronounced Golgi fragmentation BMECs. Importantly, Tjap1 knockout significantly downregulated mRNA-expression of Abcb1a, Abcb1b, Abcc4, Slc2a1, Slc7a1, Slc7a5 and Tfrc, while Abcg2 was upregulated. At the protein level, a decrease in the protein levels of Abcb1, Abcc4, Slc2a1, Slc7a1, and Tfrc was observed in Tjap1 knockout cEND cells. Conclusions: In BMECs, Tjap1 is a cis-Golgi-associated protein required for the structural integrity of the Golgi apparatus. Its deletion is associated with Golgi fragmentation and significant alterations in the mRNA and protein expression of drug transporters and receptors at the BBB. These findings identify Tjap1 as a candidate regulator of both Golgi architecture and the BBB transporter profile in vitro, with potential implications for modulating drug transport across the BBB."

The literature underscores that these technologies, when combined with non-viral delivery platforms, provide a roadmap for early-stage (presymptomatic) therapeutic intervention in ALS.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe synthesis of high-throughput multi-omics data, including single-cell transcriptomics and AI-driven structural modeling, provides a quantitative basis for identifying TDP-43-dependent cryptic splicing in motor neurons. Integrating these diagnostic insights with advanced delivery vectors (lipid nanoparticles, engineered exosomes) allows for the targeted, brain-penetrant correction of pathogenic molecular programs before significant neurodegeneration ensues.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm shift in treating amyotrophic lateral sclerosis (ALS) relies on identifying the convergence of genomic instability and RNA metabolism. TDP-43, an RNA-binding protein, regulates splicing to repress non-conserved cryptic exons.

Recent advances show that \"Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction.\" This diagnostic precision facilitates targeting: \"Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity.\" \n\nThe challenge of neurotoxicity is addressed by identifying these events presymptomatically, as \"This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation.\" To enable treatment, \"non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration.\" Furthermore, AI/computational approaches are optimizing these systems, as \"The findings show a shift from basic vesicle characterisation toward engineered delivery systems, CNS disease applications, and translational evaluation.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Cryptic splicing in genes like *STMN2* is a direct driver of neuronal dysfunction, not merely a downstream marker.\n* PDI-mediated pathways offer a therapeutic target for disassembling pathogenic TDP-43 condensates.\n* Single-cell Raman spectroscopy serves as a label-free prognostic tool for metabolic status in disease models.\n* Non-viral nanocarriers can be functionally modified with peptides to achieve receptor-mediated transcytosis across the BBB.\n* Early intervention is feasible because transport deficits and molecular signatures often precede clinical motor neuron loss.\n* cGAS-mediated innate immune signaling acts as an upstream modulator of TDP-43-driven splicing errors.\n* Inhibiting kinases like SGK1 can improve microglial phagocytosis and debris clearance in ALS models.\n* Biomimetic nanoplatforms derived from neural stem cells can be used for precise, site-specific therapeutic delivery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Current therapies are primarily symptomatic and have not consistently demonstrated prevention of disease progression. This review introduces Programmable gene modulation networks, a systems-level framework that integrates CRISPR/Cas technologies with nanotechnology-enabled brain delivery for precision intervention in Parkinson's disease. Advanced CRISPR modalities, including CRISPR interference, activation, base editing, prime editing, and epigenetic editing, are evaluated for reversible and targeted modulation of disease-relevant gene networks. Non-viral nanocarrier platforms, such as lipid nanoparticles, polymeric systems, and exosome-mimetic vesicles, are discussed for overcoming blood-brain barrier limitations and improving brain-specific delivery. The review further emphasizes translational challenges, including delivery efficiency, off-target effects, long-term safety, manufacturing scalability, and regulatory considerations. By integrating molecular network biology, programmable gene regulation, and translational decision-making, this review provides a roadmap for developing next-generation disease-modifying therapies for Parkinson's disease.\n\nID: 42399370\nTitle: Therapeutic targeting of the conserved region within the low-complexity domain of TDP-43 is neuroprotective and extends survival in amyotrophic lateral sclerosis mice.\nAbstract: Autosomal dominant mutations in TARDBP, encoding TAR DNA-binding protein 43 (TDP-43), cause amyotrophic lateral sclerosis (ALS), and TDP-43 pathology is a hallmark of multiple aging-associated neurodegenerative diseases. Despite its pathological role, effective therapies remain limited by the lack of safe, potent molecules targeting TDP-43 neurotoxicity. Here we show that the conserved \u03b1-helical region spanning residues 320-340 (conserved region or CR) is a therapeutically actionable target for TDP-43 neurotoxicity. Deletion of CR markedly suppressed TDP-43-induced neuronal death. Structure-based virtual screening identified XL20, a brain-penetrant small molecule that engages CR and confers neuroprotection without affecting TDP-43 splicing activity. XL20 alleviated motor neuron loss, extended survival in TDP-43 p.Ala315Thr ALS mice and enhanced neuronal function in p.Gln331Lys induced pluripotent stem cell-derived human ALS motor neurons. Mechanistically, targeting CR suppressed TDP-43 mitochondrial localization and restored mitochondrial function, likely through liquid-liquid phase separation. Our findings highlight CR as a therapeutic target for TDP-43-associated neurodegeneration and support CR-binding small molecules as therapeutic candidates.\n\nID: 42392383\nTitle: Gingipains as macromolecular mediators at the periodontal-brain interface: Mechanistic, diagnostic, and therapeutic evidence in Alzheimer's and Parkinson's diseases.\nAbstract: Chronic periodontitis, driven by Porphyromonas gingivalis, has emerged as a modifiable risk factor for Alzheimer's disease (AD) and Parkinson's disease (PD) the two most prevalent and socioeconomically burdensome neurodegenerative disorders through systemic dissemination of its signature cysteine proteases, gingipains (RgpA, RgpB, Kgp). This narrative critical review is explicitly scoped to AD and PD, the only neurodegenerative conditions for which postmortem detection of gingipains in affected brain regions, mechanistic evidence from cellular and animal models, and clinical epidemiological data currently exist in sufficient depth to support an integrated synthesis. Robust meta-analyses confirm that periodontitis is associated with elevated AD/PD risk (OR/HR 1.2-3.5), while gingipains have been detected in a high proportion (>85-90%) of postmortem AD/PD brains, correlating with tau/\u03b1-synuclein pathology, neuroinflammation, and neuronal loss. Mechanistic studies in cellular and animal models demonstrate that gingipains can disrupt blood-brain barrier integrity via tight-junction cleavage, trigger NF-\u03baB/NLRP3-driven glial activation, catalyse amyloid-\u03b2/\u03b1-synuclein seeding, induce tau truncation/hyperphosphorylation, and precipitate mitochondrial oxidative damage, thereby generating self-amplifying neurotoxic cascades. Salivary gingipain activity offers a non-invasive, high-sensitivity biomarker candidate for early risk stratification that may outperform conventional fluid markers in prodromal cohorts. Therapeutically, small-molecule gingipain inhibitors have shown neuroprotective effects in preclinical models (e.g., atuzaginstat/COR388 failed primary endpoints in the Phase 2/3 GAIN trial but demonstrated subgroup benefits in P. gingivalis-positive participants; the next-generation inhibitor LHP588 is advancing in the Phase 2 SPRING trial). Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity. This review provides an integrated, isoform-resolved framework linking gingipain structure-function to neurodegeneration. While associative and mechanistic evidence is compelling, definitive causation in humans and disease-modifying efficacy require further validation through biomarker-guided clinical trials. Precision inhibition of gingipains represents a promising upstream strategy for addressing a potentially modifiable microbial contributor at the oral-brain interface.\n\nID: 42388231\nTitle: Biodegradable lipid nanoparticles for genome editing in the brain via intrathecal administration.\nAbstract: Messenger RNA (mRNA)-based nonviral delivery of gene editors offers transformative potential for therapeutic genome editing in neurological diseases, but efficient and safe delivery to the brain remains a formidable challenge due to the restrictive blood-brain barrier. Intrathecal administration provides a clinically validated route to bypass this barrier, yet the design principles for biodegradable lipid nanoparticles (LNPs) optimized for central nervous system (CNS) delivery remain poorly defined. Here, we synthesized a 200-member combinatorial library of structurally diverse, biodegradable ionizable lipids using the Passerini three-component reaction. High-throughput in vivo screening identified P3B, a lead lipid incorporating degradable linkages and optimized ionizable head groups, which enables potent and well-tolerated intrathecal mRNA delivery. In Ai9 reporter mice, P3B-LNPs encapsulating Cas9 mRNA/sgRNA induced robust and widespread tdTomato expression in neurons and astrocytes across multiple brain regions, achieving substantially higher editing efficiency than the clinical benchmark DLin-MC3-DMA (MC3). In LumA reporter mice, P3B-LNPs mediated efficient adenine base editing, restoring luciferase expression throughout the brain with 14.8% on-target correction and minimal off-target activity. Compared with MC3, P3B-LNPs exhibited enhanced tolerability, with attenuated inflammatory responses and a safety profile supportive of repeated dosing. These findings establish P3B-LNPs as a potent, safe, and biodegradable platform for genome editing in the brain and underscore the power of combinatorial lipid chemistry and high-throughput in vivo screening to accelerate the development of next-generation LNPs for CNS-targeted mRNA therapeutics.\n\nID: 42352457\nTitle: Engineered Exosomes in Precision Neuro-Oncology: Mechanisms, Therapeutics, and Translational Challenges.\nAbstract: Exosomes are small vesicles released by cells that have attracted growing interest as drug delivery vehicles, particularly for brain diseases, where getting therapeutics across the BBB remains a fundamental problem. While conventional platforms such as liposomes, polymeric nanoparticles, and viral vectors often suffer from immune clearance and poor brain accumulation, engineered exosomes leverage natural cellular transport mechanisms to cross the BBB, protect cargo from degradation, and enable biocompatible interactions with target cells. This review takes a mechanistic and translational look at how exosomes are being engineered for CNS disorders, with a particular focus on glioblastoma. We cover exosome biogenesis through ESCRT-dependent and ESCRT-independent pathways, and how the competition between Rab27-driven secretion and Rab7-driven lysosomal degradation determines how many exosomes a cell releases, which has direct consequences for therapeutic production. We then discuss cargo loading strategies, from genetic approaches where donor cells are engineered to package specific molecules during biogenesis to physical methods like electroporation and sonication applied to isolated vesicles, alongside surface modification techniques for directing exosomes toward specific cell types. In glioblastoma, engineered exosomes have shown real promise for delivering chemotherapeutics across the BBB, targeting glioma stem cells, enabling CRISPR-based gene editing, and functioning as combined treatment and imaging tools. Applications in stroke and neurodegenerative diseases, where engineered exosomes carrying microRNAs and neuroprotective cargo have produced encouraging preclinical results, are also discussed. Scalable manufacturing and consistent targeting remain the hardest unsolved problems, and we outline emerging approaches including bioreactor-based production, programmable cargo loading, and patient-specific exosome design that are beginning to address these gaps. Overall, the progress reviewed here suggests that engineered exosomes are moving from an interesting biological concept toward a practically viable platform for CNS drug delivery.\n\nID: 42343570\nTitle: STMN2 protein depletion via translation deficits and stress granules in amyotrophic lateral sclerosis.\nAbstract: STMN2 is an abundant neurospecific protein dysregulated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). We previously reported that cellular stress can lead to STMN2 loss due to TDP-43 nuclear condensation. Here, using human and murine neuronal cell models, multiple pharmacological tools, in situ single-molecule analysis of translation and RNA localisation, and longitudinal analysis of neuronal fitness/survival, we establish TDP-43-independent mechanisms of STMN2 depletion under stress. We find that human STMN2 protein level is extremely labile under acute high-magnitude stress. Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing. We further show that STMN2 protein level is highly sensitive to chronic translation deficits, such as those elicited by prolonged low-grade stress. We find that low pre-stress STMN2 sensitises neuronal cells to stress-induced apoptosis, whereas moderately increased STMN2 is protective under stress. Finally, we demonstrate that STMN2 mRNA is upregulated in non-TDP ALS (ALS-FUS) models, which may compensate for translation/stress granule defects in this disease subtype. Consistent with the compensation hypothesis, STMN2 mRNA is also upregulated in the relatively spared (cortex), but not severely affected (spinal cord), CNS regions in ALS-TDP. In conclusion, our study implicates two common denominators in neurodegeneration - dysregulation of translation and stress granules - in STMN2 depletion, independent of TDP-43 loss of function. It also describes an RNA-based compensatory mechanism in ALS underling the unique vulnerability of neurons with developing TDP-43 pathology.\n\nID: 42340456\nTitle: Viral Infections and Neurodegenerative Diseases: Reinterpreting the Crosstalk Through a Dual-Role Lens.\nAbstract: Neurodegenerative diseases (NDDs) are multifactorial disorders with increasing evidence implicating viral infections in their pathogenesis. However, current reviews often catalog virus-disease associations without integrating this evidence into a unified conceptual model that also accounts for the therapeutic potential of viral platforms. This review investigates recent literature to propose a \"dual-role\" model for viruses in NDDs. We analyze how diverse viruses (e.g., HSV-1, HIV, EBV, and SARS-CoV-2) converge on shared pathogenic pathways, including protein misfolding, chronic neuroinflammation, and mitochondrial dysfunction, across different NDDs. Paradoxically, engineered viral vectors derived from neurotropic viruses are being investigated as tools for targeted gene therapy. To address these therapeutic applications of viruses, this review also provides an in-depth report of the various viral vector technologies developed. The approaches involved in designing rationally engineered viral vectors based on various adeno-associated virus serotypes through rational design, directed evolution and machine learning strategies, as well as the lentiviral and herpes simplex virus-based platform are described. Different strategies that have been used to incorporate large and/or small payloads such as gene replacement, RNA interference, microRNA cassettes, CRISPR-based gene editing (base editing, prime editing, CRISPRa and CRISPRi) and the double AAV systems to deliver larger transgene cassette have also been reviewed. This review further includes various routes of administration including intrathecal, intracerebroventricular and convection-enhanced delivery with the use of Focused Ultrasound. The constraints imposed by the Blood-Brain Barrier are discussed, especially the approach using receptor-mediated transcytosis for crossing. The review also critically evaluates obstacles toward clinical translation of viral vectors due to various factors including immunogenicity, the presence of pre-existing neutralising antibodies and dose-dependent toxicity, illustrated by the fatal outcome of ASPIRO and DMD trials. Finally, this review concludes with other promising non-viral approaches such as lipid nanoparticle and extracellular vesicles. Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors.\n\nID: 42316301\nTitle: Intrathecal (G4C2)149 delivery in C9orf72-deficient mice yields mild motor dysfunction and ALS/FTD pathological hallmarks.\nAbstract: A repeat expansion in C9ORF72 is the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), yet existing mouse models incompletely engage spinal regions implicated in disease. Here, an adeno-associated virus encoding (G4C2)149 repeats was delivered via neonatal intrathecal injection, achieving widespread CNS expression with robust spinal cord targeting. This approach was applied to mice with graded loss of endogenous C9orf72 to interrogate both gain- and loss-of-function mechanisms. Longitudinal motor, behavioral, and pathological analyses revealed that repeat expression primarily drives mild, progressive muscle weakness, whereas coordination deficits were largely genotype dependent. Subtle gait abnormalities and hyperactivity were also observed. Within spinal motor regions, repeat-expressing mice exhibited dipeptide repeat protein accumulation, reduced NeuN-positive area, fewer motor neurons, glial activation, sparse phosphorylated TDP-43 pathology, and increased cryptic TDP-43 splicing. Cross-domain correlations further linked repeat expression, spinal pathology, and motor dysfunction. Collectively, these findings establish that CNS-wide repeat expression combined with reduced C9orf72 produces a coherent, mild ALS/FTD model.\n\nID: 42313307\nTitle: Microglia-driven neuroinflammatory signaling in neurodegeneration: mechanisms and therapeutic opportunities.\nAbstract: Neuroinflammation has been identified as a major component to the pathogenesis and progression of many neurodegenerative illnesses, going beyond its traditional role as a protective immune response within central nervous system (CNS). There is growing evidence that persistent activation of peripheral immune pathways, microglia and astrocytes causes progressive neurodegeneration, synaptic loss and progressive neurodegeneration. This review examines the mechanisms of microglia- driven neuroinflammatory signaling and its involvement in major neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and Huntington's disease. Key neuroinflammatory mechanisms covered in depth including microglial activation, astrocyte reactivity, peripheral immune cell infiltration, cytokine dysregulation, and blood brain barrier (BBB) disruption. This review also emphasizes the role of neuroinflammation in acute neurological symptoms and mental and cognitive impairments. Glial activation markers, inflammatory cytokines, BBB proteins and kynurenine pathway metabolites are emerging as promising biomarkers for disease diagnosis and monitoring. Additionally, the potential of new mathematical and systems level computational models to describe intricate neuroimmune interactions and forecast the course of disease and treatment results is investigated. Current and emerging therapies targeting neuroinflammation include anti-inflammatory and immunomodulatory drugs, lifestyle interventions, stem cell approaches, gene-editing technologies and nanoparticle-based drug delivery systems. Despite significant progress, translating preclinical findings into effective clinical therapies remains challenging. Future developments in integrative neuroimmune modeling, biomarker-guided therapies and precision medicine may make it possible to create individualized treatments plans targeted at reducing neuroinflammation and enhancing the course of neurodegenerative illnesses.\n\nID: 42310715\nTitle: Exosome engineering and molecular tools for targeted therapy of brain-infecting pathogens: delivery systems, signaling pathways, and therapeutic applications.\nAbstract: Brain infections, caused by various pathogens (such as viruses, bacteria, fungi, or parasites), have proven challenging to treat due to limited drug diffusion through the blood-brain barrier and the presence of intracellular reservoirs. As biologically derived nanocarriers, exosomes have emerged as viable candidates for crossing physiological barriers and effectively delivering target molecules into the central nervous system. This review aims to summarize what is currently known about exosome biogenesis, cargo sorting, and immunological function in relation to infectious disease. In addition, it provides information on how different pathogens have taken advantage of exosomal pathways to increase their virulence and modulate the immune response, while also suggesting options for the therapeutic engineering of exosomes. It critically evaluates technological advances made in exosome engineering, such as CRISPR/Cas9-based cargo loading, ligand-directed surface modification of exosomes, targeted delivery of nucleic acids, and creation of stimuli-responsive release systems for exosome cargo for their potential application as precision therapies against pathogens that infect the brain. Pharmacokinetic data and biodistribution studies, along with studies examining how route of administration, inflammatory status, and receptor mediated uptake affect CNS targeting efficacy reflect that exosome engineering offers a novel platform for creating precision therapeutics against pathogens that infect the brain.\n\nID: 42295787\nTitle: TDP-43 Aggregation: The Healthy-Toxic Balance of the Prion-Like Domain.\nAbstract: TAR DNA-binding protein 43 (TDP-43) is a ubiquitously expressed RNA-binding protein that plays essential roles in RNA metabolism, including transcription, splicing, transport, and stability. Pathological TDP-43 aggregates have become a defining hallmark of neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and a large subset of frontotemporal lobar degeneration (FTLD). In the last decade, increasing evidence has challenged the initial thought of TDP-43 condensates as a purely pathological event, highlighting instead the physiological relevance of reversible self-association, polymerization and liquid-liquid phase separation (LLPS) in regulating TDP-43 functions. In this review, we provide an integrated overview of the structural determinants governing TDP-43 two-faced polymerization, with a particular focus on the prion-like domain and its parallelism with prion proteins. Indeed, while physiological assemblies support normal RNA processing, the dysregulation of LLPS by either disease-associated mutations, altered RNA-binding, aberrant post-translational modifications, or proteolytic cleavage can promote the transition toward irreversible, pathogenic aggregates. Finally, we summarize strategies aimed at eliminating TDP-43 aggregates or modulating its phase-separation behavior. Altogether, this review frames TDP-43 polymerization in both healthy and pathological conditions, offering a prion-like centered view of TDP-43 proteinopathies.\n\nID: 42268478\nTitle: CRISPR-Based Gene Therapy for Brain Disease.\nAbstract: Neurological disorders are complex and often very challenging for patients. Many of these conditions result from mutations in genes that are essential for normal function. Most existing treatments only alleviate symptoms, highlighting the urgent need for more effective therapeutic strategies. In the current drug development landscape, gene therapy offers hope as a promising approach. Specifically, CRISPR-Cas9 technology enables precise gene editing across diverse cell types and organisms. An increasing number of research groups are investigating innovative therapies and the molecular mechanisms behind neurological diseases. This review highlights the use of CRISPR-based gene therapies for various brain diseases, including multiple sclerosis, Alzheimer's, Parkinson's disease, epilepsy, stroke, and brain tumors. It consistently recognizes significant challenges in clinical applications, including overcoming the blood-brain barrier (BBB), managing off-target effects, ensuring efficient delivery, and addressing immunogenicity and ethical concerns.\n\nID: 42239172\nTitle: The retroelement-derived human protein PEG10 is a regulator of mRNA splicing in neurons.\nAbstract: Retroelements, including retrotransposons, endogenous retroviruses, and their fragments, as well as rare co-opted or domesticated retroelements, can contribute to neurodegenerative disorders and aging through modulation of gene expression and induction of neuroinflammation. Paternally Expressed Gene 10 (PEG10) is a retroelement-derived human gene that has recently been identified as a putative driver of Amyotrophic Lateral Sclerosis (ALS) and Angelman's Syndrome. PEG10 has been reported to bind nucleic acid and undergoes a complex self-processing pathway that results in gene expression changes when the protein accumulates in cells. Here, we report that PEG10 has selectivity for binding U/G-rich RNAs and influences widespread gene expression changes. PEG10 overexpression mimics the loss of TDP-43 in broad changes to gene expression, including dysregulation of mRNA splicing pathways. Specific changes to mRNA splicing were largely unique between TDP-43 knockdown and PEG10 overexpression, as classic TDP-43 targets including STMN2 were not altered by PEG10. Instead, we identified a unique role for PEG10 in regulating splicing of neuregulin 3 (NRG3), a ligand for the neuronal receptor ERBB4. In SH-SY5Y cells and in human neurons overexpressing PEG10, NRG3 protein levels were decreased along cellular processes, suggesting that these cells are less competent at signaling through the NRG3/ERBB4 axis. Using human patient data, we observed similar changes to NRG3 splicing in UBQLN2-mediated ALS, where PEG10 is accumulated, as well as in some cases of sporadic ALS. In conclusion, the retroelement-derived gene PEG10 plays an unexpected role in regulating splicing of neuronal transcripts, which mimics some of the transcript changes observed in human ALS patient samples. Ultimately, this work has implications for the study of PEG10, and mRNA splicing in neurological diseases associated with elevated PEG10 abundance.\n\nID: 42234776\nTitle: Cryptic splicing in synaptic and membrane excitability genes links TDP-43 loss to neuronal dysfunction.\nAbstract: TAR DNA binding protein 43 (TDP-43) pathology is a defining pathological hallmark of multiple neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). A major feature of TDP-43 pathology is its nuclear depletion, leading to the aberrant inclusion of cryptic exons during RNA splicing. STMN2 and UNC13A have emerged as prominent TDP-43 splicing targets, but the broader impact of TDP-43-dependent cryptic splicing on neuronal function remains unclear. Here, we report previously unidentified TDP-43 splicing targets critical for membrane excitability and synaptic function, including KALRN, RAP1GAP, SYT7, and KCNQ2. Using human stem cell-derived neurons, we showed that TDP-43 reduction induces cryptic splicing and down-regulation of these genes, resulting in impaired excitability and synaptic transmission. In postmortem brains from patients with FTD, these cryptic splicing events occurred selectively in neurons with TDP-43 pathology. Suppressing individual cryptic splicing events using antisense oligonucleotides partially restored neuronal function, and combined targeting almost fully rescued the synaptic deficit caused by TDP-43 loss. Together, our findings provide evidence that cryptic splicing in these synaptic and membrane excitability genes is not only a downstream marker but instead a direct driver of neuronal dysfunction, establishing a mechanistic link between TDP-43 pathology and neurodegeneration in ALS and FTD.\n\nID: 42199099\nTitle: Activin A in the central nervous system: Mechanistic and therapeutic insights unveiled by emerging technologies.\nAbstract: Activin A exhibits both protective and pathological roles in the central nervous system, reflecting a functional duality that complicates its therapeutic development. To decipher the underlying mechanisms responsible for these contradictions, we leverage emerging technologies that establish comprehensive cellular and spatiotemporal contexts for its signaling pathway. These approaches elucidate the mechanisms underlying central nervous system diseases and their potential therapeutic applications. In this review, we demonstrate how these advanced technologies enhance our understanding of the mechanism of activin A: CRISPR-based editing validates critical receptors such as ACVR1B in the process of remyelination; organoid and organ-on-a-chip systems model human-specific cellular interactions; spatial and single-cell multi-omics delineate expression and communication networks; and optogenetics/chemogenetics enable precise spatiotemporal control of signaling pathway activity. This technological toolkit provides a robust framework for elucidating the context-specific roles of activin A in conditions such as ischemic stroke, neurodegenerative diseases, glioma, epilepsy, and traumatic brain injury, encompassing key processes including neuroprotection, inflammation, and repair. Furthermore, these mechanistic insights inform next-generation interventions, including adeno-associated virus-mediated gene therapy for localized modulation and advanced nanodelivery systems for targeted biologic transport. Given these capabilities, artificial intelligence plays a crucial role in designing blood-brain barrier-permeable ligands and optimizing smart nanocarriers. By contrasting preclinical data with the clinical pipeline, which currently emphasizes peripheral diseases, we propose that integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement.\n\nID: 42192558\nTitle: Exosome-mediated gut-brain axis signaling in neurodegenerative diseases: Mechanisms, experimental evidence, and therapeutic perspectives-A narrative review.\nAbstract: The stomach and the brain are connected by a sophisticated two-way communication mechanism called the gut-brain axis. Extracellular vesicles, particularly exosomes, that move bioactive substances between the stomach and the brain, such as proteins, lipids, metabolites, and microRNAs, may improve the gut-brain axis. In the past years, the role of exosome-mediated communication has been recognized as significant in relation to the etiology, continued progression, and potential treatment of neurodegenerative disorders. The authors of this review article present a summary of the current understanding of the relationship of gut microbiome, exosome biogenesis, and the pathophysiological development of neurodegenerative diseases. Evidence from laboratory studies, animal studies, and newly emerging human studies suggests that microbiome-based metabolites and inflammatory mediators may modulate how exosomes are produced, what they carry, and how they interact with the blood-brain barrier. These exosomal signals may impact neuroinflammation, neuronal signaling, and the spread of pathological proteins of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease. In addition, they examine some possible ways to target the gut-brain axis from a therapeutic perspective, including manipulating the gut microbiome, providing probiotics and/or prebiotics, performing fecal microbiota transplantation, and/or using engineered extracellular vesicles as vehicles for drug delivery. The authors also outline some of the methodological differences that make it difficult to assess the effects of exosomes.\n\nID: 42178983\nTitle: Protein Disulfide Isomerase Disassembles TDP-43/G3BP1 Condensates and Antagonizes TDP-43 Pathological Aggregates.\nAbstract: Cytoplasmic mislocalization and aggregation of transactive response DNA-binding protein-43 (TDP-43) is a common pathological feature of amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration, and Alzheimer's disease with TDP-43 pathology (AD-TDP); the exact role of protein disulfide isomerase (PDI), an enzyme with chaperone activity, in modulating the pathological behavior of TDP-43 is unknown. In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target.\n\nID: 42135847\nTitle: TDP-43: [GU]-ardian of the transcriptome.\nAbstract: TDP-43 is a ubiquitously expressed, primarily nuclear DNA/RNA-binding protein implicated in neurodegenerative diseases including amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD). In this review, we examine the structure and regulation of TDP-43, how these features influence its localization and functional activity, and how their disruption may contribute to disease. Among TDP-43's diverse functions, splicing repression of nonconserved RNA sequences termed cryptic exons has emerged as especially central to human disease. TDP-43 nuclear depletion and cytoplasmic aggregation are well-established pathological features in affected neurons and glia of neurodegenerative diseases, and accumulating evidence suggests that loss of TDP-43-mediated splicing repression occurs presymptomatically in disease. Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction. Here, we synthesize current knowledge of TDP-43 biology and curate datasets from human tissues and experimental models, focusing on cryptic splicing to provide a resource for leveraging cryptic exon biology to better understand, detect, and target TDP-43 dysfunction.\n\nID: 42135750\nTitle: Maintenance and disruption of the physiological dimer structure of TDP-43 in amyotrophic lateral sclerosis and frontotemporal lobar degeneration.\nAbstract: Transactive response DNA-binding protein of 43\u00a0kDa (TDP-43) is an essential regulator of RNA metabolism, playing a pivotal role in splicing, transport, and stability. While its cytoplasmic aggregation is the pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD), recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure. Under healthy conditions, TDP-43 forms dimers via its N-terminal domain, a configuration that is crucial for its nuclear solubility and cooperative RNA binding. In this review, we propose the \"Molecular Zipper\" hypothesis to describe the maintenance of TDP-43 structural homeostasis. In this framework, the N-terminal domain acts as a stabilizing \"NTD-mediated anchor\" that keeps the protein in a functional, \"zipped\" dimeric state, effectively sequestering its aggregation-prone C-terminal regions. Pathogenic triggers-including genetic mutations, aberrant post-translational modifications such as phosphorylation and acetylation, and environmental stressors-can \"unzip\" this structure, leading to the formation of pathogenic monomers. These pathogenic monomers show increased propensity for cytoplasmic mislocalization and recruit wild-type protein into aggregates through a prion-like seeded aggregation mechanism, culminating in nuclear functional loss and cytoplasmic gain-of-toxicity. We further evaluate the emerging diagnostic landscape, focusing on methods to monitor the dimer-to-monomer ratio. Integrating prior biochemical data on TDP-43 dimerization with structural modeling enables a more coherent account of the transition from the physiological dimer to pathological conformers. The Molecular Zipper framework offers a conceptual foundation for reconciling existing experimental findings and for guiding future studies on early structural changes in TDP-43 proteinopathy.\n\nID: 42108387\nTitle: Rational Design and Optimisation of CRISPR-Cas9 Delivery Systems for Targeted Genomic Transformation.\nAbstract: The CRISPR-Cas9 genome-editing technique offers a promising therapeutic strategy for genetic disorders, including neurodegenerative diseases like Alzheimer's disease (AD), characterised by inherited susceptibility and progressive cognitive decline, as well as other hallmarks such as amyloid beta (A\u03b21-42) plaques and neurofibril tangles (NFTs). However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation. This comprehensive review compares various CRISPR-Cas9 delivery vectors, viral, nonviral and physical, with a focus on their efficacy in neurological diseases such as AD. Viral vectors viz., adeno-associated viruses (AAVs) and lentiviruses (LVs) demonstrate high transduction efficiency and BBB permeability. AAVs are preferred for their low immunogenicity, minimal toxicity, high neuronal tropism and episomal persistence, enabling sustained expression without insertional mutagenesis. LVs offer larger genetic payloads but raise concerns about genomic integration and potential oncogenesis, though integration-defective variants mitigate these risks. Nonviral vectors, including peptide and polymer-based nanoparticles, lipid nanoparticles (LNPs) and Inorganic carriers such as gold and silver nanoparticles, are less immunogenic and easier to handle but require further optimisation for in\u00a0vivo BBB crossing and endosomal escape. Physical methods such as electroporation and microinjection are suitable for in\u00a0vitro/ex vivo use, while novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis. These preclinical studies show that these technologies can successfully edit genes and provide therapeutic benefits, including amyloid reduction and cognitive improvement in AD models. Yet off-target effects, immune responses and regulatory hurdles persist. Overall, continuous innovation in delivery vector design and safety profile-targeting strategies is crucial for advancing CRISPR-Cas9 towards clinical therapies for AD-based therapies and related neurological disorders.\n\nID: 42094003\nTitle: Gasdermin D-driven pyroptosis in sepsis: mechanisms, therapeutic strategies, and clinical translation.\nAbstract: Sepsis is a life-threatening organ dysfunction that leads to 11 million annual global deaths. It is characterized by severe immune dysregulation, with gasdermin D (GSDMD)-driven pyroptosis recognized as a key pathogenic mechanism. After exposure to pathogen-associated molecular patterns (PAMPs)/damage-associated molecular patterns (DAMPs), GSDMD, activated via the canonical (caspase-1) and non-canonical (caspase-4/5/11) pathways, forms plasma membrane pores, induces cell lysis, and triggers multi-organ injury. Specifically, GSDMD pores trigger lung inflammation via alveolar macrophage pyroptosis, induce hepatic high mobility group box 1 protein (HMGB1) release, perpetuate bacteremia, cause renal microthrombosis, and disrupt the blood-brain barrier. GSDMD drives both the hyperinflammatory phase (via cytokine storm, NETosis) and the immunosuppressive phase (via lymphocyte apoptosis, T-cell exhaustion), thereby defining hyperinflammatory (GSDMD-NT >120 ng/mL) and immunosuppressive (intestinal barrier failure) endotypes. Promising therapeutic agents include disulfiram (blocking Cys191 oligomerization), anti-GSDMD mAb26.5 (decreasing mortality to 30%), and the combination of imipenem and disulfiram. Clinical translation faces challenges in terms of biomarker validation, organ-specific delivery, and phase-adapted intervention. Future research directions include AI-based drug design, exosome-mediated CRISPR knockout, clinical trials on drug repurposing, and single-cell omics-integrated stratified immunotherapy.\n\nID: 42416515\nTitle: Advances and Future Expectations in Oncolytic Virus Therapy for Glioblastoma: A Systematic Review of Clinical Trials.\nAbstract: Glioblastoma (GB), or grade IV astrocytoma, is the most prevalent primary tumor of the central nervous system (CNS). This systematic review aimed to investigate the efficacy and tolerability of virotherapy treatment for recurrent and progressive glioblastoma patients. We also examined recent progress in preclinical and clinical trials, and future perspectives. We developed a search strategy using Medical Subject Headings (MeSH) terms and keywords. Inclusion criteria were English language published and ongoing clinical trials that involved patients undergoing virotherapy for glioblastoma. We searched through PubMed, Embase, Ovid, Scopus, Cochrane databases and https://Clinicaltrials.gov from inception until May 9th, 2025. Two independent reviewers screened records, extracted data, and assessed risk of bias (ROB2). No meta-analysis was performed due to heterogeneity. PROSPERO CRD420250636791. Of 975 records screened, 43 studies (24 published, 19 ongoing) enrolled 462 virotherapy patients. Most common adverse events: headache (n=145), fatigue (n=83) and fever (n=78). Risk of bias was moderate to serious in most studies. We encountered several limitations, including high heterogeneity, reporting inconsistencies, and small sample sizes. Most patients experienced disease stabilization. However, objective response and complete remission occurred infrequently. A small proportion of patients achieved long-term survival, suggesting that virotherapy could be effective in specific subgroups. While oncolytic virus therapy is generally tolerated, neurotoxicity remains the most significant risk. Adverse effects were mostly Grade 1-2. Some trials (notably with HSV-1 or NDV) had severe events. Symptoms were often transient and manageable but need closely monitoring. However, the observed heterogeneity, limited data standardisation, and lack of randomized controlled trials, besides tumor heterogeneity, antiviral immunity and immunosuppressive microenvironment, necessitate further research to identify predictive biomarkers and optimize therapeutic protocols. We also suggest further trials on novel delivery methods, such as the nanoparticles, to enhance blood-brain barrier (BBB) penetration.\n\nID: 42415876\nTitle: Liposomal Nanoparticulate Drug Delivery Systems: Strategies to Destabilize Biological Membranes at the Target Tissue.\nAbstract: Liposomal nanoparticulate drug delivery systems (LNDDSs) are clinically validated nanomedicine platforms seeing regular use in oncology and infectious disease. Their applications have rapidly expanded with several tissue targeting formulations in early-phase clinical trials. Beyond small molecular drugs, LNDDSs are increasingly employed for delivery of nucleic acid therapeutics, such as ribonucleic acid (RNA) based vaccines and immunomodulators. Recent advances in nanomaterials have enabled LNDDSs not only to transport therapeutic agents across systemic biological barriers but also to selectively destabilize plasma and organelle membranes, such as endosomes and mitochondria, addressing a wide range of diseases. This review systematically examines design strategies for LNDDSs that traverse key biological barriers focusing on the blood-tumor barrier, blood-brain barrier, and lymphatic transport barriers. We further explore approaches including fusogenic, pH-, redox- and, enzyme-sensitive and externally (ultrasound and thermal) triggered LNDDSs to facilitate internalization and membrane destabilization for specific organelle-targeting. The mechanisms and representative formulations and of membrane interactions, and clinical progress are discussed. Finally, the translational opportunities and challenges, and future perspectives for rational design of next-generation LNDDSs are addressed.\n\nID: 42411221\nTitle: Phyto-Nanotherapeutics for Alzheimer's Disease: Current Progress and Future Perspectives.\nAbstract: Alzheimer's Disease (AD) is a prevalent neurodegenerative disorder characterized by progressive cognitive and behavioral impairment and represents a major cause of dementia worldwide. It primarily affects the elderly population. The disease is marked by progressive neuronal damage, leading to impairments in cognition, behavior, emotions, and communication. Although currently available therapies provide symptomatic relief, they fail to alter disease progression, necessitating the development of more effective therapeutic strategies. Phytoconstituents have gained considerable attention due to their neuroprotective properties and multitargeted mechanisms of action against pathways implicated in AD. However, their clinical application is limited by poor Blood-Brain Barrier (BBB) permeability, low bioavailability, and inadequate solubility. Nanotechnology offers a promising approach for brain-targeted drug delivery by enhancing the therapeutic efficacy of phytoconstituents through advanced nanocarrier systems. This review explores the synergistic potential of phytoconstituents and nanocarriers for the management of AD, aiming to improve therapeutic outcomes and overcome existing limitations. It further highlights the integration of medicinal plant-based compounds with nanotechnology as a novel strategy for AD treatment. The combination of nanocarriers and phytoconstituents may facilitate enhanced BBB penetration and improved neuroprotection. Notably, nanomedicine- based approaches, including phytoconstituent-loaded nanoparticles and liposomes, demonstrate significant potential to overcome delivery barriers and enable efficient drug transport to the brain.\n\nID: 42406649\nTitle: Tiered Evaluation of Carbosilane Dendrimer-siRNA Nanoplatform from Single-Cell Biocompatibility to Blood-Brain Barrier Model Dynamics and Murine Alzheimer Model Behavior Assessment.\nAbstract: Blood-brain barrier (BBB) transport remains a primary constraint on achieving predictable central nervous system exposure for Alzheimer's disease (AD) therapeutics, motivating the evaluation of delivery platforms with barrier-resolved and functionally relevant end points. We assessed a carbosilane dendrimer (G3Si PEG6000) and its siRNA dendriplex using a tiered, upstream strategy spanning cell internalization, DNA damage screening, BBB model integrity and permeability, and in vivo AD-relevant murine model learning. At the cellular level, the dendrimer enhanced intracellular siRNA-associated signal with predominantly cytoplasmic localization, and siRNA complexation attenuated genotoxicity relative to the noncomplexed carrier. In a BBB triculture model, barrier function was preserved without sustained transendothelial electrical resistance (TEER) loss, and complementary tracer flux readouts showed time- and formulation-dependent, nonmonotonic changes, including TEER-permeability decoupling consistent with nonuniform perturbation and time-dependent changes in barrier-associated paracellular responses. In APOE4 knock-in mice, dendriplex treatment increased platform-zone crossings in the Morris Water Maze probe trial, whereas target-quadrant time showed only a modest, nonsignificant trend. Collectively, these integrated results indicate that siRNA complexation improves the BBB-relevant safety-performance balance of G3Si PEG6000 and supports further studies that directly link brain exposure and target engagement to cognitive outcomes.\n\nID: 42406553\nTitle: EphB1-Mediated Transient Blood-Brain Barrier Opening Facilitates a Ferritin-Based Nanotherapeutic for Alzheimer's Disease.\nAbstract: The treatment of Alzheimer's disease (AD) is severely hampered by the blood-brain barrier (BBB), which limits the delivery of therapeutic agents like donepezil (DPZ), an acetylcholinesterase inhibitor. While DPZ has multi-faceted benefits, its clinical efficacy is constrained by poor BBB penetration, requiring high doses that lead to significant side effects. To overcome this, we developed a brain-targeted nanotherapeutic utilizing apoferritin (AFn) nanoparticles loaded with DPZ (AFn-DPZ). We demonstrate that this platform, by binding to the EphB1 receptor on the blood-brain barrier, enables transient and reversible opening of the blood-brain barrier, thereby facilitating efficient and targeted drug delivery. Following intravenous administration in an AD mouse model, AFn-DPZ exhibited enhanced brain accumulation and sustained release of DPZ. This targeted delivery inhibited acetylcholinesterase activity, reduced amyloid plaque burden, alleviated neuroinflammation, attenuated oxidative damage, restored mitochondrial function, and upregulated the expression of brain-derived neurotrophic factor (BDNF). Consequently, AFn-DPZ treatment significantly improved cognitive performance compared to free DPZ. Our findings establish EphB1-mediated facilitation of BBB traversal as a promising strategy for enhancing nanotherapeutic delivery to the brain, offering a potent approach to address the complex pathology of AD.\n\nID: 42403540\nTitle: Magnetic Nanoparticles as a Theranostic Platform in Brain Tumor Treatment: Surmounting the Bench-to-Bedside Barriers.\nAbstract: Malignant brain tumors, particularly glioblastoma, remain one of the greatest challenges in oncology due to their invasive nature, therapeutic resistance, and protection by the blood-brain barrier. Decades of limited therapeutic progress underscore the need for new treatment strategies beyond conventional modalities. Magnetic nanoparticles have emerged as a promising theranostic platform that integrates high-precision imaging, targeted delivery, and synergistic therapy. In this review, we outline a mechanistic framework for magnetic nanoparticle applications, with a focus on the link between ferroptosis and immune activation. We discuss how the intrinsic properties of magnetic nanoparticles can be engineered to induce iron-dependent ferroptotic cell death, which may help overcome apoptosis resistance and also trigger immunogenic cell death. This magnetic nanoparticle-induced immunogenic cell death may shift the immunosuppressive brain tumor microenvironment from a \"cold\" state toward a more immune-active phenotype, thereby supporting combination immunotherapy. We also examine key translational challenges and potential solutions, including quantitative magnetic particle imaging-guided therapeutic dosimetry, focused ultrasound-mediated delivery strategies, and issues related to Chemistry, Manufacturing, and Controls and regulatory science. By analyzing these translational challenges, this review aims to highlight practical considerations for advancing magnetic nanoparticle-based therapies toward clinical neuro-oncology.\n\nID: 42403537\nTitle: Nanomedicine for Depression: From Blood-Brain Barrier Delivery to Neuroimmune-Barrier-Plasticity Network Reprogramming.\nAbstract: Depression is a heterogeneous and recurrent brain disorder in which neuroinflammation, blood-brain barrier dysfunction, oxidative and mitochondrial stress, and impaired neuroplasticity interact within the neurovascular-glial-neuronal unit. This mechanism-oriented integrative review examines how engineered nanosystems may move beyond brain entry toward lesion-directed modulation of the neuroinflammation-barrier-neuroplasticity axis. We first synthesize the pathological nodes that sustain depression-related network dysfunction and then classify current nanotherapeutic strategies into three categories: small-molecule nanodelivery systems, nucleic acid nanocarriers, and functional nanoplatforms, including lipid and polymeric nanoparticles, inorganic and nanozyme-based systems, biomimetic membrane-coated nanoparticles, and engineered extracellular vesicles, including exosomes. Unlike previous nanosynthesis-focused or catalogue-style nanocarrier reviews, this review organizes the field around a disease-mechanism framework rather than material type alone, emphasizing barrier-state navigation, glial-neuronal-subcellular targeting, stimulus-responsive release, and coordinated modulation of inflammation, vascular integrity, redox homeostasis, and synaptic plasticity. We further argue that nanoplatforms should be evaluated not only by brain accumulation but also by patient stratification, engagement of defined pathological nodes, multimodal biomarker evidence of network-level modulation, manufacturability, and safety under repeated administration. Major translational bottlenecks include insufficient subtype-specific patient selection, limited human relevance of current stress- and inflammation-based models, uncertain biodistribution and long-term neurotoxicity, constraints in scaling up nose-to-brain delivery, batch-to-batch variability, cargo instability, immunogenicity, and unclear regulatory classification of complex biologic or combination products. Finally, we propose a pathological-network-guided precision nanomedicine framework that integrates blood-brain barrier status assessment, liquid biopsy and imaging biomarkers, human-relevant validation models, and scalable quality control to guide future platform design and clinical translation. This review provides a disease-mechanism-centered roadmap for transforming nanomedicine for depression from delivery optimization into precision network-oriented intervention.\n\nID: 42403028\nTitle: Design-Expert Assisted Formulation Development, Optimization, and Evaluation of Selegiline and Biochanin A Loaded Self-Nanoemulsifying Drug Delivery System.\nAbstract: The goal of the work was to formulate, optimize, and evaluate liquid-Self-nanoemulsifying drug delivery system (L-SNEDDS) co-loaded with Selegiline (SEL), a monoamine oxidase type B (MAO-B) inhibitor, and Biochanin A (BCA), a potent adjunctive neuroprotective agent found in Trifolium pratense, to enhance oral delivery and accelerate anti-Parkinsonian efficacy for the management of Parkinson's disease (PD). Propylene glycol was chosen as co-surfactant, Tween 80 as surfactant, and peppermint oil as oil phase after excipients screening, as this combination exhibited the broadest emulsification region in pseudo-ternary phase diagram. A systematic Quality-by-Design (QbD) approach was adopted, and formulation variables were optimized using Design-Expert software to obtain an optimized L-SNEDDS formulation with desirable physicochemical attributes. Dilution of the optimized SNEDDS led to the spontaneous formation of a stable aqueous nanoemulsion exhibiting a droplet size of 110.9\u2009nm, polydispersity index (PDI) 0.265, transmittance of 98.86\u2009\u00b1\u20090.37%, zeta potential of -16.3\u2009mV, viscosity of 6.35\u2009\u00b1\u20092.51\u2009cP, self-emulsification time of 27.35\u2009s, and conductivity of 196.23\u2009\u00b1\u20090.324 \u03bcS cm-1. In vivo studies showed that SEL-BCA-loaded SNEDDS exhibited better oral bioavailability than pure SEL-BCA suspension. Notably, SNEDDS achieved higher brain Cmax values for SEL (5.6\u2009\u00b1\u20090.41\u2009\u03bcg\u2009mL-1) and BCA (13.84\u2009\u00b1\u20091.14\u2009\u03bcg\u2009mL-1), as well as elevated plasma concentrations of SEL (6.51\u2009\u00b1\u20090.43\u2009\u03bcg\u2009mL-1) and BCA (762.65\u2009\u00b1\u200916.82\u2009\u03bcg\u2009mL-1). Collectively, the results underscore the potential of the SEL-BCA SNEDDS as a combinational delivery platform that could improve the effectiveness of combination therapy for the management of PD.\n\nID: 42401216\nTitle: Dual PLGA nanoparticles co-encapsulating P5091 and Resveratrol synergistically target the USP7-MDM2-P53 axis for glioma therapy.\nAbstract: Glioma, a Grade-IV brain tumor, often exhibits functional suppression of P53 signaling due to aberrant stabilization of MDM2 by the deubiquitinase USP7, presenting a therapeutically exploitable vulnerability that remains under-utilised because of poor drug bioavailability and limited blood-brain barrier penetration. Here, we developed a rationally designed PLGA-based dual-loaded nanoformulation co-encapsulating USP7 inhibitor P5091 and P53-modulating polyphenol Resveratrol, to significantly attenuate the USP7-MDM2-P53 axis. Guided by synergy analysis, nanoparticles were formulated at an optimized molar ratio enabling controlled and sustained drug release with favourable physicochemical stability. Dual nanoencapsulation significantly enhanced synergistic cytotoxicity in glioma cells and 3D spheroids by inducing apoptosis through significant P53 restoration. Dual co-encapsulation improves pharmacokinetics and suppresses tumor growth with improved survival in orthotopic glioma model without any obvious vital organs histological damage. These findings highlight a mechanism-guided nanotherapeutic strategy for glioma treatment.\n\nID: 42400341\nTitle: ROS-Responsive Quercetin Nanoparticles Improve the Prognosis of Traumatic Brain Injury by Inhibiting Aberrant Nrf2-Keap1 Signaling Pathway Activation.\nAbstract: Traumatic brain injury (TBI) is one of the leading causes of mortality and disability worldwide, with secondary injury recognized as a critical therapeutic target. Quercetin (QR), a natural flavonoid, exerts antioxidant and anti-inflammatory effects by modulating the Nrf2-Keap1 pathway and shows neuroprotective potential in various neurological disorders. In this study, network pharmacology analysis identified 496 overlapping targets of QR and TBI, further highlighting the pivotal role of the Nrf2-Keap1 pathway in TBI treatment. However, the poor blood-brain barrier (BBB) permeability and low bioavailability of QR hinder effective brain-targeted delivery and limit its clinical translation. To address these challenges, we developed CAQK peptide-modified, reactive oxygen species (ROS)-responsive nanoparticles (C-PPS/Q), using PPS120 as the core for targeted QR delivery. C-PPS/Q exhibited ROS-triggered QR release, significantly enhanced HT22 cell uptake in\u00a0vitro, reduced ROS levels and apoptosis. In a TBI mouse model, C-PPS/Q specifically accumulated at the lesion site, prolonged the half-life of QR, demonstrated excellent biocompatibility, preserved BBB integrity, attenuated neuroinflammation, inhibited aberrant Nrf2-Keap1 pathway activation, and markedly improved neurological function. Collectively, C-PPS/Q nanoparticles effectively mitigate secondary brain injury after TBI and represent a promising brain-targeted therapeutic strategy for TBI management.\n\nID: 42392408\nTitle: Hijacking radiotherapy-induced chemokines with self-assembled molecular decoys for glioblastoma radio-immunotherapy.\nAbstract: Glioblastoma (GBM) management is critically impeded by the blood-brain barrier (BBB) and acquired radioresistance. To overcome these hurdles, we engineered a genetically modified biomimetic \"nanosponge\" (CCR2@VCNPs) designed to synergistically sensitize radiotherapy (RT) and remodel the tumor microenvironment. The nanoplatform consists of a self-assembled core composed of Verteporfin and Celecoxib (VCNPs), which provides high drug loading capacity and enables coordinated delivery of both agents. By cloaking this self-assembled core with macrophage membranes overexpressing CC chemokine receptor 2 (CCR2), the nanoparticles achieve dual-mode targeting: mimicking leukocyte-endothelium interactions for BBB transcytosis and exploiting the CCL2/CCR2 axis for active chemotactic navigation. Notably, the surface CCR2 serves as a \"molecular decoy\" to intercept RT-induced CCL2, effectively blocking the infiltration of immunosuppressive myeloid cells. Upon tumor accumulation, the self-delivered Verteporfin acts as a potent radiosensitizer by generating singlet oxygen and inhibiting the YAP/TAZ pathway, while Celecoxib (CXB) concurrently abrogates radio-induced immunosuppression by severing the PGE2/COX-2 signaling axis. This integrated strategy promotes robust immunogenic cell death (ICD), effectively transforming the \"cold\" GBM niche into a \"hot\" immunological phenotype. In orthotopic GBM mouse models, CCR2@VCNPs significantly prolonged median survival and suppressed tumor recurrence. By integrating molecular self-assembly with genetic membrane engineering, offers a comprehensive solution to therapeutic resistance and holds great promise for clinical GBM management.\n\nID: 42392306\nTitle: Global Trends and Evolving Frontiers in Intranasal Delivery for CNS Diseases (2000-2025): A Bibliometric Analysis and Systematic Review.\nAbstract: Intranasal administration (nose-to-brain delivery) has emerged as a pivotal non-invasive strategy to bypass the blood-brain barrier (BBB) for treating central nervous system (CNS) disorders. However, the exponential growth of literature in this domain presents challenges in grasping the holistic research trajectory and identifying emerging hotspots. This study conducted a comprehensive bibliometric analysis of 4,009 publications retrieved from the Web of Science Core Collection (WoSCC) spanning from 2000 to 2025. Tools including VOSviewer, CiteSpace, and R-bibliometrix were employed to map spatiotemporal trends, collaborative networks, and keyword evolution. The analysis reveals a robust upward trend in global research output, predominantly driven by China and the United States. Keyword clustering identified five major research sub-domains: Alzheimer's disease, Oxytocin (behavioral/psychiatric applications), Stroke and Neuroinflammation, Brain Tumors, and Nanoparticles. Burst detection analysis elucidates a distinct paradigm shift in scientific focus: early investigations prioritized mucosal absorption mechanisms and tolerance; the focus subsequently transitioned to specific therapeutic agents (e.g., insulin, oxytocin); and most recently, the field has been dominated by the optimization of delivery vectors, specifically lipid-based nanoparticles and exosomes. While nanotechnology has become the current technological frontier for enhancing brain targeting, a critical gap remains between promising preclinical results and clinical translation. Future research must prioritize the development of biomimetic delivery systems and highly predictive translational models to bridge the divide between bench and bedside. This review provides a strategic roadmap for researchers to navigate current trends and address the barriers hindering clinical application.\n\nID: 42390437\nTitle: A Brain-Targeted DNA Delivery Nanocarrier Modulator for Synergistic Therapy of Parkinson's Disease.\nAbstract: The pathological characteristics of Parkinson's Disease (PD) are multifactorial, encompassing the aggregation of \u03b1-synuclein, mitochondrial dysfunction, and oxidative stress, necessitating the adoption of multitarget therapeutic strategies. In this study, a borneol-modified carboxymethyl chitosan nanoparticle system (BC/P/HCR NPs) was developed, aiming to codeliver curcumin, rosmarinic acid, and plasmid DNA (pDNA) targeting the SNCA gene for synergistic therapeutic intervention in PD. Borneol is capable of enhancing the permeability of the blood-brain barrier (BBB), while carboxymethyl chitosan contributes to improving the solubility of curcumin and preventing premature drug release. In a C57BL/6 mouse model of PD, BC/P/HCR NPs demonstrated enhanced penetration through the BBB, effectively alleviating motor dysfunction and reducing neuronal damage by downregulating the expression of \u03b1-synuclein, restoring mitochondrial function, and mitigating oxidative stress. These findings underscore the potential of BC/P/HCR NPs as a multifunctional nanotherapeutic platform for addressing the complex pathological features of PD.\n\nID: 42388375\nTitle: Membrane-camouflaged metal-phenolic nanomedicines for the treatment of ischemic stroke via relieving oxidative stress and neuroinflammation.\nAbstract: Ischemia-reperfusion injury (IRI) following thrombolytic therapy significantly influences the ischemic stroke outcomes. Here, we develop M@EFE NPs, a biomimetic nanomedicine, to alleviate the reperfusion injury. This nanomedicine is constructed by encapsulating Edaravone into the metal-phenolic nanoparticles self-assembled from epigallocatechin gallate (EGCG) and iron ions (Fe3+), and further coating with macrophage membranes. This design integrates the antioxidant and anti-lipid peroxidation properties of the EGCG-Fe3+ nanoparticles with the inflammatory targeting capacity of macrophage membranes. Following systemic administration, M@EFE NPs are able to penetrate the blood-brain barrier and target the ischemic regions, thereby inhibiting oxidative damage, protecting neurons, and ultimately improving stroke outcomes. In vitro, the nanomedicine can effectively scavenge reactive oxygen species, inhibit lipid peroxidation, and enhance cell survival. In murine middle cerebral artery occlusion models, M@EFE NPs could reduce infarct volume, attenuate neuronal apoptosis and neuroinflammation, and improve motor recovery and long-term survival. This study presents a promising combinatorial nanotherapeutic strategy for ischemic stroke, providing insights into biomimetic nanomedicine for treating cerebral IRI.\n\nID: 42386537\nTitle: Development of Nucleic Acid-Loaded Nanobubbles for Ultrasound-Mediated Therapeutic Applications.\nAbstract: Ultrasound has attracted considerable attention not only as a diagnostic imaging modality but also as a physical trigger for drug delivery system (DDS). Ultrasound irradiation applied in combination with gas-filled bubbles can induce cavitation and transiently increase the permeability of cellular membranes, thereby enhancing the intracellular delivery of therapeutic molecules. Our research group has developed ultrasound-responsive gas-containing lipid nanoparticles, initially termed bubble liposomes (BLs) and later referred to as nanobubbles (NBs), as carriers for nucleic acid delivery. Early studies indicated that BLs facilitated the efficient cytoplasmic delivery of small interfering RNA under ultrasound irradiation. Subsequent investigations expanded the platform to include diverse nucleic acids, including plasmid DNA and microRNA, and revealed therapeutic efficacy in disease models such as hindlimb ischemia. Further developments include strategies for brain-targeted gene delivery mediated via blood-brain barrier modulation and the design of stable anionic NBs with the capacity to load nucleic acids via cationic intermediates. More recently, polysaccharide-coated NBs and microfluidic preparatory methods have been assessed with a view to improving delivery performance and particle uniformity. These advances highlight the potential utility of nucleic acid-loaded NBs as theranostic platforms for the integration of ultrasound imaging and gene delivery. The continued development of this technology may contribute to the advancement of next-generation ultrasound-mediated DDS.\n\nID: 42381886\nTitle: Unlocking the healing power of Berberine: A promising aid for multiple sclerosis.\nAbstract: Multiple sclerosis (MS) is a debilitating autoimmune disorder characterized by inflammatory demyelination and progressive neurodegeneration within the central nervous system (CNS). Despite advances in disease-modifying therapies (DMTs), current treatments primarily mitigate relapses and slow disease progression but fall short in comprehensively addressing cumulative disability or neurodegeneration. Berberine (BBR), a naturally occurring isoquinoline alkaloid, has emerged as a promising therapeutic candidate due to its potent immunomodulatory, anti-inflammatory, and neuroprotective properties. In this narrative review, we synthesize the molecular mechanisms underpinning BBR's effects on MS pathology and evaluate preclinical evidence from MS-relevant animal models. Studies in experimental autoimmune encephalomyelitis (EAE) -the primary MS model-and the cuprizone (CPZ) -induced demyelination model demonstrate that BBR (typically 5-300\u202fmg/kg in preclinical protocols) reduces pro-inflammatory cytokines, modulates immune responses, and promotes remyelination-processes critical for counteracting MS-associated neurodegeneration. BBR modulates key signaling pathways, including JAK/STAT and SPHK1/S1P, which are pivotal in attenuating immune-mediated damage and preserving blood-brain barrier (BBB) integrity. Despite its therapeutic potential, challenges such as poor bioavailability and suboptimal pharmacokinetics have spurred investigations into advanced delivery systems. Nanoformulations, particularly BBR-loaded iron oxide nanoparticles (BBR-IONP), have shown superior efficacy in preclinical models by enhancing CNS delivery and improving remyelination outcomes. By highlighting BBR's multifaceted bioactivities, this review underscores its promise as a complementary or alternative approach to address unmet needs in MS management, while acknowledging the critical need for clinical trials to validate these preclinical findings.\n\nID: 42381326\nTitle: Overcoming Physiological Barriers in Brain Tumor Therapy: Advances in Nanomedicine, Ultramolecular Pharmaceuticals, and Targeted Drug Delivery.\nAbstract: Targeting brain tumors remains a formidable challenge due to the presence of complex physiological barriers, notably the blood-brain barrier (BBB), the blood-brain tumor barrier (BBTB), and the nose- tobrain barrier. These barriers hinder effective drug delivery, limiting therapeutic efficacy. This review provides a comprehensive analysis of the anatomical and molecular characteristics of these barriers, with particular emphasis on the heterogeneity of the BBTB and its implications for targeted drug transport. A detailed overview of various brain tumor types-including glioblastoma, pediatric brain tumors, and brain metastases-is presented alongside a critical evaluation of existing therapeutic modalities. The review highlights the advancement of ultramolecular pharmaceuticals specifically engineered to circumvent the BBTB, focusing on both transvascular and cell-mediated delivery mechanisms. The role of nanomedicine in modulating the immune response and altering the tumor microenvironment is explored as a promising avenue for enhancing therapeutic outcomes. Particular emphasis is placed on nanogels as a versatile and efficient drug delivery platform. Key fabrication techniques such as precipitation polymerization, emulsion polymerization, self-assembly, and micro-templating methods are thoroughly discussed, alongside strategies for polymer crosslinking to enhance stability and functionality. In addition, the review addresses preclinical evaluation strategies, including in vitro models (e.g., BBB-mimicking systems, tumor spheroids) and in vivo studies in animal models, to assess the safety, biodistribution, and therapeutic efficacy of nanogel-based systems. Finally, current clinical progress, challenges, and future perspectives are presented, underscoring the urgent need for innovative, targeted, and personalized drug delivery approaches. This review aims to guide future research in overcoming delivery obstacles and improving outcomes for patients with brain tumors through the strategic integration of advanced nanotechnology and molecular targeting.\n\nID: 42381038\nTitle: Dual-drug-loaded nanohydrogel for intraoperative local application: sequential release-mediated spatiotemporal targeting of diverse secondary injury mechanisms to improve long-term prognosis in traumatic brain injury.\nAbstract: Traumatic brain injury (TBI) can induce both primary and secondary brain injuries. Hampered by a multitude of constraints, including the complexity of secondary injury pathophysiological mechanisms, the selective permeability of the blood-brain barrier (BBB), and the side effects of therapeutic agents, systemic monotherapy has demonstrated limited efficacy in improving the long-term prognosis of TBI patients. Therefore, there is an urgent need to develop novel therapeutic strategies that can bypass the BBB, avoid systemic complications, and target multiple secondary injury mechanisms simultaneously. An injectable dual-drug-loaded nanohydrogel system was synthesized and its characteristics were evaluated. A mouse controlled cortical impact (CCI) model was established, and the nanohydrogel was locally administered intraoperatively. The neurological prognosis of mice was observed in both acute and chronic phases. Multiple methods, including evans blue assay, magnetic resonance imaging, transmission electron microscopy, western blot, enzyme-linked immunosorbent assay, and immunofluorescence staining, were used to evaluate the cerebral edema, BBB integrity, neuroinflammation, neuronal death/survival, angiogenesis, and neurogenesis after TBI. The nanohydrogel hybridizes hemoglobin (Hb) nanoparticles (NPs) with brain-derived neurotrophic factor (BDNF), uses these as the core to synthesize polydopamine (PDA) NPs, and loads dexamethasone (DEX) on their surface. In vitro drug release experiments confirmed that BDNF@Hb-PDA@DEX@gel had a high drug-loading rate and sequential sustained-release characteristics. The hydrogel matrix exhibited hemostatic and antibacterial effects. Both in vitro and in vivo experiments showed that the nanohydrogel could effectively reduce the acute-phase inflammatory response, protect BBB integrity, and alleviate cerebral edema by releasing DEX. In the late stage, it could promote brain tissue repair by releasing BDNF, including angiogenesis, neurogenesis, and neuron survival. The therapeutic efficacy of this dual-drug sequential delivery system was significantly superior to that of DEX monotherapy, and it could improve both acute and chronic neurological functions. By virtue of local sequential and sustained release of multiple drugs, the injectable nanohydrogel-based dual-drug delivery system can target multiple secondary injury mechanisms of TBI and exert spatiotemporal therapeutic effects, which provides a new strategy for the effective management of complex secondary brain injury and the improvement of long-term prognosis in TBI.\n\nID: 42380984\nTitle: BBB-aware stimuli-responsive and biomimetic nanomedicines for glioblastoma.\nAbstract: Glioblastoma (GBM) poses a tremendous challenge because it causes substantial morbidity and mortality. Treatment remains constrained by the tightly regulated blood-brain barrier (BBB) and the heterogeneous blood-brain tumor barrier (BBTB), which together severely limit drug delivery to tumor tissue. Nanomaterial-based drug delivery systems offer an opportunity to overcome the short half-life, low bioavailability, and poor BBB penetration that restrict conventional GBM therapeutics. Nanotechnology also provides safe, effective, and targeted drug delivery systems that enhance penetration, stability, and therapeutic efficacy. This review discusses biomaterials-based nanomedicine platforms for GBM, with a focus on lipid-based carriers, polymeric nanoparticles, dendrimers, inorganic nanomaterials, and biomimetic nanosystems designed to interact with the BBB/BBTB. We summarize how passive and active brain-targeting strategies are combined with endogenous and exogenous stimuli-responsive designs (pH/redox sensitivity, magnetic hyperthermia, photothermal/photodynamic therapy, and ultrasound-triggered systems) to enhance intratumoral accumulation and anti-GBM efficacy. Overall, this review discusses recent advances in BBB-aware, stimuli-responsive, and biomimetic nanomedicines for GBM, and outlines their therapeutic potential alongside persistent challenges in safety, large-scale manufacturing, and clinical translation.\n\nID: 42370176\nTitle: Molecular design of MRI probes for targeting amyloid-\u03b2 species: from in vitro binding to in vivo imaging.\nAbstract: The aberrant aggregation of amyloid-\u03b2 (A\u03b2) is a central pathological marker of Alzheimer's disease (AD) and shows different neurotoxic properties in various forms, such as monomers, oligomers, fibers and plaques. In recent years, great progress has been achieved in the molecular design and the development of magnetic resonance imaging (MRI) probes targeting A\u03b2 species. They provide powerful tools for the early diagnosis and pathological investigation of AD. Here, we systematically review the molecular design strategies and recent advances in A\u03b2-targeted MRI probes. First, we introduce the molecular pathological basis of A\u03b2 aggregation and the importance of A\u03b2 as an imaging target. Second, we detail the core components of probe design, including the selection of targeting ligands (e.g., peptide mimetics, small molecules, and antibody fragments), optimization of signal units (e.g., Gd(III), Mn(II), superparamagnetic iron oxide nanoparticles (SPIONs), and \u00b9\u2079F), and the delivery strategies to enhance blood-brain barrier (BBB) penetration. We focus on how the probes achieve the transition from high-affinity binding in vitro to high-contrast imaging in vivo by means of changes in proton relaxation times (T1/T2) or the chemical exchange saturation transfer (CEST) effect upon binding to A\u03b2. Furthermore, the imaging performance of various probes (small molecule probes, nanoprobes, and smart responsive probes) in transgenic AD models is compared and evaluated, and the challenges related to sensitivity, specificity, and biosafety are discussed. Finally, we discuss future directions for A\u03b2-targeted MRI probes, including oligomer-specific probes, multimodal imaging probes, and theranostic platforms that include both diagnostic and therapeutic functions. Through interdisciplinary innovation in molecular design, the next generation of MRI probes is expected to play a key role in preclinical research, early diagnosis, and therapeutic evaluation of AD.\n\nID: 42370027\nTitle: Focused ultrasound-mediated blood-brain barrier opening enhances delivery of Rg3 ginseng nanoparticles in a Parkinson's disease mouse model.\nAbstract: The blood-brain barrier (BBB) severely restricts the delivery of neuroprotective compounds to the brain, limiting therapeutic strategies for Parkinson's disease (PD). Ginsenoside Rg3, a bioactive component of ginseng, has demonstrated neuroprotective potential, but its efficacy is constrained by poor BBB permeability. Here, we evaluated focused ultrasound (FUS)-mediated BBB opening (FUS BBBO) to enhance delivery of Rg3-loaded nanoparticles in a rotenone-induced mouse model of PD. Localized FUS sonications were applied to induce transient BBB disruption, followed by intraperitoneal administration of FITC-labeled Rg3 nanoparticles. In vivo and Ex vivo fluorescence imaging confirmed a significant increase in brain accumulation of nanoparticles after FUS BBBO. While Rg3 nanoparticle treatment alone showed moderate increases in ATP levels and Complex I activity, FUS alone produced comparable trends with slightly higher recovery. The combination treatment with FUS-mediated BBBO demonstrated higher mean values (ATP: 0.27\u00a0\u00b1\u00a00.06; Complex I: 1.98\u00a0\u00b1\u00a00.41) compared to the PD group, along with improvements in motor performance. These findings suggest that FUS-BBBO may enhance the delivery of Rg3 nanoparticles to the brain and support mitochondrial function. Overall, the combination approach showed a trend toward improved outcomes; however, further studies are required to confirm these effects and establish therapeutic potential for solid statistical analysis.\n\nID: 42369375\nTitle: Mechanistic insights into the synaptic damage-repair and regeneration processes in neurodegenerative Alzheimer's disease: phytochemicals as neuroprotective agents.\nAbstract: Synaptic failure is one of the earliest and most significant contributors to the cognitive decline in Alzheimer's disease (AD), preceding extensive neuronal loss. Although amyloid beta (A\u03b2) plaques and neurofibrillary tangles (NFTs) of tau protein characterize the disease, memory impairment primarily results from the gradual deterioration of synaptic communications. This decline is caused by a complex interaction among mitochondrial energy deficits, cytoskeletal instability, disrupted exosomal signaling, and immune-mediated synaptic pruning. Mitochondrial dysfunction, particularly affecting complexes I and IV, leads to reduced ATP production, faulty mitophagy and disrupted calcium (Ca2+) homeostasis, placing the synapse under constant metabolic stress. Elevated reactive oxygen species (ROS) further activate stress pathways, including p38 MAPK and JNK, contributing to synaptic protein damage and impaired long-term potentiation (LTP). Furthermore, tau hyperphosphorylation destabilizes the neuronal cytoskeleton, weakening dendritic spine integrity and synaptic connectivity. At the same time, A\u03b2 alters the cargo carried by exosomes, facilitating the spread of pathogenic A\u03b2 and tau species between the neurons and modulating microglial activation and complement-mediated synaptic pruning. Additionally, emerging studies highlight the role of NETosis in exacerbating neuroinflammation and compromising the blood-brain barrier (BBB) integrity, thereby increasing synaptic damage. In contrast, phytochemicals such as resveratrol, ginkgolide B, curcumin, ferulic acid, epigallocatechin gallate (EGCG), and quercetin exert neuroprotection by restoring redox balance, altering exosomal communications, stabilizing cytoskeletal signaling, and reducing neuroinflammation. Moreover, delivery techniques such as nanoparticles and engineered exosomes enhance BBB permeability and enable targeted synaptic intervention. Overall, this review summarizes current mechanistic findings and highlights the potential of phytochemicals as multitarget therapeutic agents for synaptic repair and functional recovery in AD.\n\nID: 42367116\nTitle: Nano-Based Therapeutics in Rare Disease Management: Current Perspectives, Challenges, and Unmet Needs.\nAbstract: Rare diseases, affecting approximately 8% of the global population, remain among the most underserved areas in modern medicine due to their low prevalence, complex genetic origins, and limited commercial incentives for drug development. Rare neurological disorders, in particular, pose formidable challenges owing to their progressive nature and the difficulty of delivering thera-peutics across the blood-brain barrier. This review explores the emerging role of nanomedicine in transforming rare disease management through precision-targeted drug delivery, enhanced bioavail-ability, and the ability to bypass biological barriers. Nanoparticles (NPs)-including PEGylated NPs, lipid-based NPs, polymeric NPs, and hybrid formulations-are being engineered to deliver therapeu-tic agents for gene therapy, enzyme replacement, and RNA interference. These platforms have shown promise in treating conditions such as Krabbe disease, Niemann-Pick type C1, spinocerebel-lar ataxia type 1, and prion diseases. Additionally, nanotherapeutics are being investigated for pulmonary and congenital lung disorders, including cystic fibrosis and idiopathic pulmonary fibro-sis, with improved tissue penetration and reduced systemic toxicity. The review also highlights the potential of AI-integrated diagnostics and personalized nanomedicine to address disease heterogene-ity and improve patient outcomes. Despite these advances, significant barriers remain, including regulatory complexity, high development costs, and limited clinical models. The manuscript calls for collaborative innovation across academia, industry, and regulatory bodies to accelerate clinical translation and ensure equitable access. By bridging molecular innovation with patient-centric care, nanotherapeutics offer a paradigm shift in the diagnosis and treatment of rare diseases, potentially redefining therapeutic landscapes and improving the quality of life for affected individuals.\n\nID: 42366104\nTitle: An Improved Brain-Penetrating Nanoformulation of the VIPR2 Antagonist Peptide KS-133 for Treating Cognitive Impairment in Schizophrenia.\nAbstract: In 2024, we reported a brain-penetrant formulation of the vasoactive intestinal peptide receptor 2 (VIPR2) antagonist peptide KS-133 that mitigated cognitive dysfunction in the VIPR2 hyperactivation mouse model of schizophrenia. In this formulation, KS-133 was encapsulated in the hydrophobic core of nanoparticles (NPs) coated with 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine-KS-487 (DPPE-KS-487), a conjugate of the cyclic peptide KS-487 and DPPE produced by a click reaction that binds low-density lipoprotein-related protein 1, enabling blood-brain barrier penetration upon subcutaneous injection. However, the click reaction generated multiple positional isomers and manufacturing required repetitive cycles of ultrasonication at high and low temperatures, posing challenges for industrial scalability. In the current study, we coated KS-133-containing NPs with 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-KS-487 (DSPE-KS-487), a novel conjugate of KS-487 with DSPE produced through a non-click method, thus eliminating positional isomers, and also established a simplified manufacturing process allowing a unidirectional transition from ultrasonication at high to low temperatures. This formulation remained physically and chemically stable for at least 12 months under refrigeration, with no changes in particle size, zeta potential, KS-133 content, or KS-487 presentation level. The formulation also exhibited brain penetration and therapeutic efficacy against VIPR2 agonist-induced novel object recognition impairment in mice comparable to those of DPPE-KS-487 NPs. Furthermore, no systemic side effects of hematologic, brain, heart, liver, and lung toxicity were detected following daily injections to mice for two weeks at five times the effective dose. This new KS-133 formulation incorporating DSPE-KS-487 as a brain-penetrant shuttle is a promising drug candidate for the treatment of cognitive dysfunction in schizophrenia.\n\nID: 42358359\nTitle: Global research trends and hotspots of exosome-mediated drug delivery across the blood-brain barrier: a bibliometric study from 2015 to 2025.\nAbstract: The blood-brain barrier (BBB) is a major obstacle to targeted drug delivery for central nervous system (CNS) diseases. Although liposomes and polymeric nanoparticles have improved brain drug delivery, limitations remain in BBB targeting, long-term biocompatibility, and in vivo clearance. Exosomes are endogenous nanoscale extracellular vesicles with favourable biocompatibility, low immunogenicity, and BBB-crossing potential. Therefore, this bibliometric study summarises the current research status, future research trends, and challenges in the more specific field of exosome-mediated BBB drug delivery. A comprehensive search was conducted across the Web of Science Core Collection (WoSCC), PubMed, and Embase databases for relevant English-language literature on exosome-mediated drug delivery across the blood-brain barrier from 2015 to 2025. WoSCC served as the primary source for bibliometric analysis. PubMed and Embase databases were used for supplementary validation. Software such as VOSviewer, CiteSpace, and R-bibliometrix was employed for literature visualisation analysis. This study included 1,365 relevant articles from the WoSCC database, and the annual publication volume showed a steady upward trend. China and the United States significantly lead in both the number of publications and the number of core contributing institutions in this field. Co-occurrence analysis of keywords showed that research hotspots are mainly focused on exosomes, the blood-brain barrier, drug delivery, and Alzheimer's disease. PubMed and Embase were used as supplementary validation databases, including 1,089 and 1,517 records, respectively. Their annual publication trends, major countries/regions, core journals, and keywords/themes were generally consistent with WoSCC, supporting the macro-level stability of the bibliometric findings. Unlike previous bibliometric analyses that mainly focused on overall trends in CNS exosome research, this study focuses specifically on the direction of exosome-mediated drug delivery across the BBB. The findings show a shift from basic vesicle characterisation toward engineered delivery systems, CNS disease applications, and translational evaluation. Mammalian-derived exosomes remain dominant, while plant-derived vesicles, AI-assisted design, biomimetic hybrid nanovesicles, and gut-brain axis strategies are emerging areas of focus. Future research should prioritise systematic platform comparisons, standardised evaluation, quality control, scalable production, long-term safety, and regulatory pathways.\n\nID: 42357281\nTitle: Tjap1/Pilt Is a cis-Golgi-Associated Protein Required for Golgi Integrity and Normal Drug Transporter Expression in Brain Microvascular Endothelial Cells In Vitro.\nAbstract: Background: Brain microvascular endothelial cells (BMECs) form the blood-brain barrier (BBB), a highly selective interface that restricts paracellular diffusion and regulates the transport of nutrients and drugs into the central nervous system via specialized transporters and receptors. Tight junction-associated protein 1 (Tjap1), also termed protein incorporated later into tight junctions (Pilt), has been localized to tight junctions (TJs) in epithelial cells and to the trans-Golgi network in fibroblasts; however, its expression, subcellular localization, and functional significance in BMECs are still unknown. Methods: We characterized Tjap1 subcellular localization in mouse and human BMEC cell lines as well as primary mouse BMECs by immunofluorescence with and without pharmacological Golgi disruption by treatment with Brefeldin A, Golgicide A or Pitstop 2. CRISPR/Cas9-mediated Tjap1 knockout cells were generated and examined with regard to their Golgi morphology using immunostaining. Tjap1 mRNA localization was examined by RNAscope in situ hybridization. Quantitative real-time PCR and Western blot was performed to assess the expression of BBB-associated efflux transporters, solute carrier transporters, and cellular receptors in control and Tjap1 knockout cells. Results: Tjap1 predominantly localized to the cis-Golgi compartment, co-localizing with Gm130 rather than Tgn38, and was absent from TJs in BMECs. Tjap1 knockout induced pronounced Golgi fragmentation BMECs. Importantly, Tjap1 knockout significantly downregulated mRNA-expression of Abcb1a, Abcb1b, Abcc4, Slc2a1, Slc7a1, Slc7a5 and Tfrc, while Abcg2 was upregulated. At the protein level, a decrease in the protein levels of Abcb1, Abcc4, Slc2a1, Slc7a1, and Tfrc was observed in Tjap1 knockout cEND cells. Conclusions: In BMECs, Tjap1 is a cis-Golgi-associated protein required for the structural integrity of the Golgi apparatus. Its deletion is associated with Golgi fragmentation and significant alterations in the mRNA and protein expression of drug transporters and receptors at the BBB. These findings identify Tjap1 as a candidate regulator of both Golgi architecture and the BBB transporter profile in vitro, with potential implications for modulating drug transport across the BBB.\n\nID: 42357271\nTitle: Folic Acid-Guided PLGA-Zein Core-Shell Nanoparticles for Co-Delivery of Temozolomide and Ellagic Acid to Overcome PARP-Mediated Chemoresistance in Glioblastoma.\nAbstract: Background: Glioblastoma (GBM) remains a lethal malignancy due to temozolomide (TMZ) resistance and limited drug penetration across the blood-brain barrier, largely driven by hyperactive DNA damage repair mechanisms such as poly (ADP-ribose) polymerase (PARP). To address these challenges, we developed folic acid-targeted PLGA-zein hybrid core-shell nanoparticles for the codelivery of the alkylating agent TMZ and the natural PARP inhibitor Ellagic acid (FA-TMZ/EA-PZ-CS NPs), thereby enabling simultaneous enhancement of drug delivery and suppression of chemoresistance pathways. Methods and Results: The dual-drug nanoplatform was fabricated using a double-emulsion solvent evaporation method and functionalized via EDC/NHS-mediated folic acid conjugation to promote receptor-mediated uptake. Physicochemical characterisation confirmed uniform spherical morphology, high colloidal stability, efficient drug encapsulation, and sustained biphasic drug release consistent with a core-shell diffusion mechanism. In LN229 glioblastoma cells, folic acid conjugation significantly enhanced cellular internalisation and cytotoxic efficacy compared to free drugs and non-targeted nanoparticles. Combination index analysis revealed strong synergism between TMZ and ellagic acid, resulting in markedly reduced IC50 values. Mechanistic studies demonstrated apoptosis induction, increased DNA damage, inhibition of cell migration at sub-cytotoxic concentrations, and downregulation of PARP gene expression. Conclusion: Overall, this study establishes a targeted core-shell nanotherapeutic strategy that integrates chemotherapy with DNA repair inhibition to overcome TMZ resistance, offering a mechanistically sound strategy that serves as a foundational framework for future translational research.\n\nID: 42396564\nTitle: Defining spinal motor neuron subtypes across development: from embryonic specification to postnatal maturation.\nAbstract: Spinal motor neurons are essential for translating neural activity into coordinated muscle contraction, yet defining their functional subtypes across development remains a persistent challenge. While embryonic patterning establishes the initial positional and molecular framework of motor neuron identity, substantial refinement continues during early postnatal life as intrinsic electrophysiological properties, synaptic connectivity, and neuromuscular interactions mature. A major limitation in the field is the lack of temporally stable and functionally validated molecular markers that can reliably distinguish motor neuron subtypes across developmental stages, particularly during neonatal maturation when subtype-specific physiological features are emerging. In this review, we synthesize classical developmental studies with recent advances in single-cell transcriptomics, chromatin accessibility profiling, and multimodal approaches linking gene expression with electrophysiological and anatomical features. Focusing on lumbar spinal motor neurons that underlie locomotor behavior, we discuss how transcriptional programs, activity-dependent mechanisms, and non-cell-autonomous signals converge to shape subtype-specific maturation trajectories. We propose that motor neuron subtype identity is best understood as a dynamic molecular and physiological state shaped by developmental timing, circuit context, and activity-dependent mechanisms, rather than as a fixed category defined by a single marker. From this perspective, early postnatal life represents a sensitive window of identity consolidation during which molecular programs and functional properties become aligned. Establishing temporally robust subtype markers and integrating molecular and physiological datasets will be essential for resolving motor neuron diversity and for improving our understanding of subtype-selective vulnerability in neuromuscular diseases. While this review emphasizes embryonic and early postnatal development, understanding how molecular subtypes stabilize in the adult spinal cord, despite ongoing activity-dependent physiological plasticity, remains an essential reference point for defining temporally robust motor neuron identities.\n\nID: 42393685\nTitle: Structural-functional network decoupling in early stage amyotrophic lateral sclerosis reveals cell-type specific transcriptional signatures.\nAbstract: Amyotrophic lateral sclerosis (ALS) involves widespread brain network dysfunction, yet the molecular mechanisms linked to these alterations remain poorly understood. We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology.\n\nID: 42387584\nTitle: SGK1-mediated deficits in microglial phagocytosis drive pathological progression in amyotrophic lateral sclerosis.\nAbstract: Alterations in microglial function and transcriptomic profiles are major pathological hallmarks of amyotrophic lateral sclerosis (ALS). However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models.\n\nID: 42385702\nTitle: Recurrent patterns of TOP1-mediated neuronal genomic damage shared by major neurodegenerative disorders.\nAbstract: Amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD) represent two major categories of neurodegenerative disorders-TAR DNA-binding protein 43 (TDP-43) and tau proteinopathies-for which the mechanisms driving neuronal death remain unclear. Single-cell whole-genome sequencing of 469 neurons from C9ORF72 ALS, C9ORF72 FTD, AD, and control brains revealed increased somatic single-nucleotide variants (sSNVs) and insertions/deletions (sIndels) in all three diseases. Mutational signature analysis identified a disease-associated sSNV signature consistent with oxidative damage and an sIndel process affecting 22% of ALS, 76% of FTD, and 61% of AD neurons-but only 2% of control neurons-resembling signature ID4, previously linked to topoisomerase 1 (TOP1)-mediated mutagenesis. Rapid approach to DNA adduct recovery (RADAR) assays confirmed increased TOP1-DNA covalent complexes, and duplex sequencing confirmed the increased sIndels and identified single-strand events as likely precursor lesions. TOP1-associated sIndel mutagenesis and genome instability thus represent a mechanism shared by both TDP-43 and tau neurodegeneration.\n\nID: 42385279\nTitle: Comparative pathophysiology and pathology of transient ischemic attack, ischemic stroke, and reperfusion injury: Mechanistic and therapeutic perspectives.\nAbstract: Transient ischemic attack (TIA), ischemic stroke, and ischemia-reperfusion (IR) injury represent a continuum of cerebrovascular disorders with distinct clinical and pathophysiological features. While TIA is classically considered benign, recent studies reveal subtle yet potentially deleterious neuronal and glial changes. Ischemic stroke typically results in sustained hypoperfusion, infarction, blood-brain barrier (BBB) disruption, and robust neuroinflammatory cascades. IR injury, though potentially beneficial through vessel recanalization, paradoxically induces oxidative stress, cytokine release, and secondary infarction. This review systematically compares the molecular, histological, and behavioral profiles of these three conditions. Key differences include patterns of neuronal death, glial activation, oxidative damage, and BBB integrity. Human neuroimaging data and animal model histology are integrated to illustrate characteristic features across the spectrum. We also discuss current experimental models and their translational relevance, highlighting challenges in modeling comorbidities and chronic outcomes. Precision medicine strategies considering sex, age, and immune background-are emphasized as essential for advancing diagnostics and optimizing therapeutic efficacy. Emerging multimodal therapies, including pharmacological agents, stem cells, gene editing, and nanomedicine, hold promise but require rigorous validation. A deeper mechanistic understanding of each condition will be crucial for tailoring treatment strategies and bridging the translational gap in ischemic cerebrovascular disease.\n\nID: 42378967\nTitle: Temporal trajectories underlying adult neuronal diversity.\nAbstract: This review integrates longitudinal transcriptomic and functional studies to examine how embryonically born neurons acquire their adult identities. Single-cell atlases reveal that in addition to gene expression changes, neuron types undergo shifts in subtype composition as they mature from nascent to mature identities. Shifts in subtype composition likely reflect the unique sequence of developmental events followed by each neuron and explain why, in some neuron types, functional diversity in adults is not fully explained by adult transcriptomics alone. Instead, adult neuronal identity is best understood as a culmination of transient and stable transcriptomic changes over time that are regulated by the combinatorial action of sequentially activated intrinsic and extrinsic factors. Which factors regulate transcriptional transitions in each neuron type, how trajectories are coordinated across functionally related neurons, how chromatin states accommodate temporal changes, and whether time itself is an important factor in determining adult identity, remain open questions.\n\nID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.\n\nID: 42309815\nTitle: Stage- and Region-Dependent Proteomic Alterations in a Mouse Model of Creatine Transporter Deficiency.\nAbstract: SLC6A8 encodes the creatine transporter (CRT), which mediates creatine transport across the plasma membrane in the brain, including the blood-brain barrier and neurons. Creatine transporter deficiency (CTD), caused by pathogenic variants in SLC6A8, leads to cerebral creatine depletion and cognitive impairment. Here, we investigated the developmental molecular mechanisms underlying CTD using the pathogenic c.1681G>C (G561R) variant of Slc6a8, which corresponds to a variant identified in SLC6A8 in a patient with CTD. In vitro analyses using HEK293 cells expressing mutant mouse CRT carrying the G561R variant demonstrated impaired N-glycan maturation and plasma membrane localization of the transporter, resulting in markedly reduced creatine uptake, consistent with previous reports on the corresponding human CRT variant. To investigate the in vivo effects of this pathogenic variant, we generated CRT-G561R knock-in mice by introducing the c.1681G>C point mutation into the mouse Slc6a8 gene using the CRISPR/Cas9 system. These male mice exhibited severe reductions in brain creatine levels, postnatal growth retardation, and impaired spatial memory, despite preserved gross brain morphology. Quantitative proteomic analyses of the hippocampus and cerebral cortex during postnatal development revealed region-dependent protein alterations in CTD. The hippocampus showed pronounced early postnatal remodeling involving proteins related to actin cytoskeleton organization and vesicle-mediated membrane trafficking, whereas the cerebral cortex exhibited a more gradual response involving creatine biosynthesis-related enzymes and later-emerging mitochondrial pathways, including the mitochondrial translation machinery. These findings demonstrate stage- and region-dependent proteomic remodeling during postnatal brain development in CTD.Significance Statement Creatine transporter deficiency (CTD) causes cerebral creatine depletion and intellectual disability; however, the developmental mechanisms linking creatine loss to brain dysfunction remain unclear. We performed developmental proteomic profiling of the hippocampus and cerebral cortex using a mouse model carrying a pathogenic Slc6a8 variant identified in patients with CTD. Creatine transporter dysfunction induces distinct region- and stage-dependent molecular responses during postnatal brain maturation. The hippocampus shows early alterations in cytoskeleton-dependent membrane trafficking pathways, consistent with impaired synaptic and circuit maturation, whereas the cerebral cortex exhibits progressive metabolic and mitochondrial adaptations. These findings suggest that impaired creatine-dependent energy buffering disrupts distinct developmental programs across brain regions, potentially contributing to cognitive dysfunction by hindering early hippocampal circuit maturation.\n\nID: 42261162\nTitle: Targeting \u03b1-Synuclein Aggregation in Parkinson's Disease: A Narrative Review of Current Gene Therapy Strategies.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by the accumulation of misfolded \u03b1-synuclein (\u03b1-syn) aggregates, leading to dopaminergic neuronal loss and motor dysfunction. Current pharmacological treatments primarily provide symptomatic relief and have a limited impact on disease progression. This article presents a narrative review of emerging gene therapy approaches aimed at modulating \u03b1-syn expression, aggregation, and clearance as potential disease-modifying strategies for PD. Gene-based interventions include viral vector-mediated gene delivery, antisense oligonucleotides, RNA interference, and gene-editing technologies. Preclinical studies and early-phase clinical trials suggest that these approaches may reduce \u03b1-syn burden, improve motor outcomes, and support dopaminergic neuron preservation. Adeno-associated viral and lentiviral vectors have demonstrated promise for targeted central nervous system delivery, although challenges related to dosage optimization, regional specificity, long-term safety, and immune responses remain. Complementary strategies focusing on enhancing molecular chaperone activity and activating autophagy-lysosomal pathways have also shown potential in facilitating \u03b1-syn clearance. Despite encouraging progress, several limitations hinder clinical translation, including off-target effects, immune activation, and the need to preserve physiological \u03b1-syn functions essential for neuronal homeostasis. Future success will depend on precise molecular targeting, optimized delivery platforms, and rigorous safety evaluation through well-designed clinical trials. This narrative review summarizes current advances, key limitations, and future directions in \u03b1-syn-targeted gene therapy, highlighting its potential role in advancing PD treatment beyond symptomatic management toward disease modification.\n\nID: 42259773\nTitle: Engineering an AIEgen-based platform integrating CRISPR/Cas9 to remodel the tumor microenvironment and reinforce photo-immunotherapy against glioblastom.\nAbstract: Glioblastoma remains one of the most lethal brain tumors. Although immunotherapy and other therapeutic modalities has achieved significant therapeutic success in several malignancies, its efficacy in glioblastoma remains limited primarily due to the complex tumor microenvironment (TME) and physiological barriers such as the blood-brain barrier (BBB). In this context, nanomedicine and gene editing have emerged as promising strategies due to their unique ability to cross the BBB and protect therapeutic agents through intrinsic physicochemical properties. To overcome the physiological barriers for better therapeutic outcomes. Here, a novel aggregation-induced emission luminogen (AIEgen), NDA-DPE, was synthesized, exhibiting NIR-I to NIR-II fluorescence and dual photothermal (PTT) and photodynamic (PDT) properties through restricted intramolecular motion. Bone-derived neutrophil-based biomimetic nanoparticles (bNe@AIE/Cas9-CD73) were then prepared by integrating NDA-DPE with CRISPR/Cas9-mediated CD73 gene silencing. The neutrophil encapsulation enabled efficient BBB penetration and targeted accumulation in glioblastoma tissue. CRISPR/Cas9-CD73 downregulated CD73 expression, disrupted the ATP-adenosine axis, and reshped the immunosuppressive TME into an immuno-supportive one, increasing the therapeutic sensitivity of tumor cells. Under NIR-II excitation, bNe@AIE/Cas9-CD73 achieved fluorescence-guided PTT and PDT, inducing immunogenic cell death (ICD), stimulating immune-cell recruitment, and activating systemic antitumor immunity. bNe@AIE/Cas9-CD73 demonstrated a potent gene-photothermal-photodynamic-immune synergistic effect, significantly inhibiting glioblastoma growth and establishing a promising nanoplatform for effective and targeted glioblastoma treatment.\n\nID: 42253328\nTitle: Mechanistic Landscape and Farm to Fork Control Strategies for Streptococcus suis: An Emerging Foodborne Threat.\nAbstract: Streptococcus suis (S. suis) is an emerging zoonotic agent that now rivals classical food-borne pathogens in its global clinical burden of meningitis and septic shock. Recent epidemiological syntheses covering more than 30 countries now list over 1600 laboratory-confirmed human cases with a pooled case-fatality of about 12%, climbing beyond 18% in East Asia. The widely cited pooled case-fatality estimate derives from a PRISMA-guided systematic review and meta-analysis that searched PubMed, Scopus, Web of Science, ScienceDirect, and Google Scholar through December 2012 and pooled study-level event rates using inverse-variance methods with random-effects models when heterogeneity was present. We critically synthesize recent molecular, cellular, and translational studies to define how this swine commensal breaches host epithelial and blood-brain barriers (BBBs), subverts innate immunity, and disseminates systemically. Newly identified virulence mechanisms include serine-threonine kinase-driven claudin-5 cleavage, vimentin-dependent transcytosis, quorum-sensing control of biofilm maturation, and metabolic reprogramming that fuels neutrophil evasion. We integrate multiomics signatures with structural data to map conserved targets such as IdeSui and capsular polysaccharide that underpin next-generation conjugate and nanoparticle vaccines. Diagnostic advances spanning CRISPR-based assays and high-resolution imaging are assessed for their capacity to enable point-of-care detection. We also highlight host transcriptomic signatures that can be integrated into microfluidic chips, allowing syndromic discrimination between S. suis and pneumococcal meningitis within 40\u2009min, a critical window for targeted therapy. Finally, we present a prevention framework uniting farm biosecurity, rational antibiotic stewardship, probiotic and bacteriocin interventions, and community education. Collectively, the review delivers an up-to-date roadmap for mitigating S. suis transmission and disease, highlights outstanding knowledge gaps in host-pathogen interactions, and outlines translational priorities needed to transform bench discoveries into effective public health countermeasures.\n\nID: 42242212\nTitle: Agility training enhances motor temporal precision by reweighting spinal phase-locked commissural inhibition.\nAbstract: Agile motor action requires rapid switching between motor states while maintaining stability. Because motor output combines fast and slow muscle fibers with distinct kinetics, prolonged slow-fiber activation can broaden burst envelopes and blur within-cycle transitions, limiting temporal precision. Here, we show that agility training improves locomotor timing by selectively compressing the activity of slow motor neurons through enhancing commissural inhibition. In adult zebrafish, training increased locomotor stability and reshaped cycle structure in vivo, shortening the contraction phase while extending relaxation. Ex vivo motor-nerve recordings revealed sharper burst envelopes and reduced temporal dispersion after training, explained by a selective narrowing of slow, but not fast, motor neuron discharge within each cycle. Training enhanced phase-locked commissural inhibition during locomotion, consistent with an inhibitory gate aligned to burst offset. Finally, electrophysiology and single-cell transcriptomics associated this plasticity with increased glycinergic receptor expression in slow motor neurons. Together, our findings identify a circuit and a molecular substrate for training-induced gains in agility and suggest that motor precision can be improved by inhibitory reformatting of slow motor output rather than by uniformly increasing excitation.\n\nID: 42181874\nTitle: An integrative neuropharmacological review of Huntington's disease challenges and the role of novel formulations in addressing pharmacological\u2012pharmaceutical limitations.\nAbstract: Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by CAG repeat expansion in the huntingtin gene, leading to progressive neuronal dysfunction and neurodegeneration. Although classically defined as a brain-restricted disorder marked by striatal and cortical degeneration, increasing evidence suggests HD as a multisystem disease involving both central and peripheral pathological alterations. This review aims to provide an integrated overview of neuronal and non-neuronal mechanisms underlying HD, focusing on systemic alterations that influence disease onset, progression, and clinical variability. This review also aims to connect neuropharmacology with pharmaceutical formulation strategies, particularly emphasizing the therapeutic and drug-delivery challenges and nanotechnology-based solutions. A structured literature review was conducted using databases including PubMed, EMBASE, and Scopus. Using the appropriate keywords, original articles, clinical studies, systematic reviews, meta-analyses, and high-quality reviews were selected based on their relevance to HD pathophysiology and therapeutic strategies. HD manifests with motor, cognitive, and psychiatric disturbances; however, this review highlights that peripheral immune activation, gut microbiota dysbiosis, and multiorgan pathology are not merely secondary features but interact with neural circuits, contributing to disease heterogeneity and progression. Current therapeutic approaches are largely symptomatic, achieving minimal effectiveness in disease modification due to challenges such as poor blood-brain barrier penetration, limited target selectivity, and inter-individual variability. New strategies, such as nanotechnology-based drug delivery systems, biologics, and gene editing tools, offer advantages and support a deeper understanding of therapeutic limitations and disease mechanisms, yet their translational applicability remains constrained by limited clinical validation, safety concerns, and scalability problems. Reconceptualizing HD as a multisystem disorder provides a more comprehensive framework for therapeutic development. Integrating central and peripheral disease mechanisms with advances in targeted drug delivery and patient stratification approaches, such as sex differences, hormonal influences, and environmental factors, is essential for translational progress toward personalized therapeutic approaches. Future research should prioritize interdisciplinary approaches to bridge the gap between mechanistic discoveries and effective disease-modifying interventions.\n\nID: 42171861\nTitle: TDP-43 Acetylation at the Neuroimmune Interface: A Hypothesis-Driven Framework for Peripheral Inflammatory Stratotypes in ALS.\nAbstract: Transactive Response Deoxyribonucleic Acid-Binding Protein-43 (TDP-43) acetylation may couple motor-neuron degeneration to systemic immune orchestration in Amyotrophic Lateral Sclerosis (ALS). Upon nuclear clearance and mislocalisation, TDP-43 enters the periphery; acetylation shapes its conformation, trafficking and immunogenicity. This narrative review synthesises single-cell transcriptomics, proteomic immunoprofiling and clinical inflammatory phenotyping to examine whether site-specific acetylated TDP-43 species may be associated with peripheral inflammatory signatures relevant to ALS immunopathology. By integrating separate datasets on acetylated TDP-43, monocyte phenotypes and cytokine modules, we propose two provisional endotypes characterised by monocyte reprogramming, cytokine modules and Blood-Brain Barrier (BBB) dysfunction-each representing clinically actionable pathways. Framed as a provisional neuroimmune interface, the acetylation state is considered here as a plausible molecular correlate and potential therapeutic entry point: a measurable clue to inform pharmacological targeting and, potentially, a modifiable target via p300CREB-Binding Protein (CBP)-Histone Deacetylase (HDAC) axes or sirtuin activity. Recasting TDP-43 from neuropathological hallmark to immunoactive sentinel supports a shift from descriptive nosology to stratified immunotherapy, in which treatment allocation is informed by acetylation-defined peripheral signatures.\n\nID: 42153537\nTitle: MOTS-c, a mitochondrial-derived peptide, ameliorates lysosomal membrane permeability and improves survival of soft tissue transplantation.\nAbstract: Distal ischemic necrosis remains a major challenge in reconstructive surgery. Mitochondria and lysosomes interact via signaling and membrane contacts to maintain cellular homeostasis. Mitochondrial-derived peptide MOTS-c, encoded by the MT-RNR1/12S rRNA open reading frame, enhances mitochondrial function by reducing reactive oxygen species (ROS) and stabilizing the membrane potential, potentially preserving lysosomal integrity and reducing lysosomal membrane permeabilization (LMP). This study investigated the protective effects and underlying mechanisms of MOTS-c in ischemic flaps. RNA sequencing explored MOTS-c mechanisms in ischemic flaps. Tissue clearing, laser speckle contrast imaging and Doppler analyses revealed improved blood flow perfusion following MOTS-c treatment. Histological staining (HE, Masson, F-CHP) demonstrated enhanced angiogenesis and collagen remodeling. Western blotting, ELISA, and immunofluorescence were used to assess pyroptosis, macroautophagy/autophagy, LMP, and MAPK1/ERK2-MAPK3/ERK1-NFKB/NF-\u03baB pathway-related proteins. MOTS-c reduced endothelial pyroptosis, enhanced autophagy, and attenuated LMP in ischemic flaps. Mechanistically, in vivo overexpression of PLA2G4A/cPLA2 (phospholipase A2, group IVA (calcium, calcium dependent)) via AAV confirmed that MOTS-c enhances autophagy and reduces pyroptosis and LMP by suppressing PLA2G4A phosphorylation. Furthermore, MOTS-c inhibited PLA2G4A via the MAPK1-MAPK3-NFKB signaling cascade, thereby reducing LMP and enhancing flap survival. These findings suggest that MOTS-c restores cellular homeostasis by targeting the PLA2G4A-LMP axis, representing a promising therapeutic strategy for improving outcomes in ischemic flap surgery.Abbreviations: AA\u2009=\u2009arachidonic acid, AAV\u2009=\u2009adeno-associated virus, ACTA2/\u03b1-SMA\u2009=\u2009actin alpha 2, smooth muscle, aorta, ALs\u2009=\u2009autolysosomes, BECN1\u2009=\u2009beclin 1, CASP1\u2009=\u2009caspase 1, CQ\u2009=\u2009chloroquine, CTSB\u2009=\u2009cathepsin B, CTSD\u2009=\u2009cathepsin D, CTSL\u2009=\u2009cathepsin L, Co-IP\u2009=\u2009co-immunoprecipitation, DEGs\u2009=\u2009differentially expressed genes, ELISA\u2009=\u2009enzyme-linked immunosorbent assay, F-CHP\u2009=\u20095-FAM-conjugated collagen hybridizing peptide staining, GSDMD\u2009=\u2009gasdermin D, GO\u2009=\u2009gene Ontology, GPT/ALT\u2009=\u2009glutamic pyruvic transaminase, soluble, GOT1/AST\u2009=\u2009glutamic-oxaloacetic transaminase 1, soluble, HE\u2009=\u2009hematoxylin-eosin, HUVECs\u2009=\u2009human umbilical vein endothelial cells, IP/MS\u2009=\u2009immunoprecipitation coupled with mass spectrometry, IL1B/IL-1\u03b2\u2009=\u2009interleukin 1 beta, IL18\u2009=\u2009interleukin 18, IP\u2009=\u2009intraperitoneal injection, IV\u2009=\u2009intravenous injection, LDBF\u2009=\u2009laser Doppler blood flow, LMP\u2009=\u2009lysosomal membrane permeability, MAP1LC3/LC3\u2009=\u2009microtubule-associated protein 1 light chain 3, MAPK\u2009=\u2009mitogen-activated protein kinase, NAGLU\u2009=\u2009alpha-N-acetylglucosaminidase (Sanfilippo disease IIIB), NFKB/NF-\u03baB\u2009=\u2009nuclear factor kappa B, NLRP1\u2009=\u2009NLR family pyrin domain containing 1, NLRP3\u2009=\u2009NLR family pyrin domain containing 3, PECAM1/CD31\u2009=\u2009platelet/endothelial cell adhesion molecule 1, PLA2G4A/cPLA2\u2009=\u2009phospholipase A2, group IVA (cytosolic, calcium-dependent), PYCARD/ASC\u2009=\u2009PYD and CARD domain containing, PIK3C3/VPS34\u2009=\u2009phosphatidylinositol 3-kinase catalytic subunit type 3, PMA\u2009=\u2009phorbol 12-myristate 13-acetate, ROS\u2009=\u2009reactive oxygen speciesSQSTM1/p62\u2009=\u2009sequestosome 1, SPR\u2009=\u2009surface plasmon resonance, scRNA-seq\u2009=\u2009single-cell RNA sequencing, UMAP\u2009=\u2009uniform manifold approximation and projection, WB\u2009=\u2009western blotting.\n\nID: 42149386\nTitle: Morphine potentiates HIV infection and receptor expression in 3d brain organoids.\nAbstract: Opioid abuse is a major comorbidity of HIV, yet its direct effects on the brain remain unclear. Using iPSC-derived 3D human cerebral organoids (hCOs), we show that morphine directly upregulates HIV receptors CD4, CCR5, and CXCR4 in the absence of peripheral immune cells or a blood-brain barrier. This receptor induction drives a significant increase in HIV viral load within the CNS, revealing a brain-intrinsic mechanisms of opioid-mediated viral enhancement. These findings establish hCOs as a unique platform to investigate neuroHIV and provide critical insight into how opioids amplify CNS infection independently of peripheral factors.\n\nID: 42135512\nTitle: Integrated single-cell and spatial transcriptomic profiling in ALS uncovers peripheral-to-central immune infiltration and reprogramming.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder marked by progressive motor neuron (MN) degeneration in the brain and spinal cord. Although neuroinflammation is increasingly recognized as a hallmark of ALS, the precise molecular programs linking immune responses to MN pathology remain poorly defined. Using an integrated approach that combines single-cell and bulk RNA sequencing with spatial proteogenomics, we characterized both shared and distinct immune dynamics in peripheral blood and spinal cord tissues from patients with sporadic ALS and those carrying C9orf72 repeat expansions. Our analysis revealed broad immune remodeling in C9orf72 ALS, ALS subtype-specific and progression-associated differences in monocyte activation and antigen-experienced CD8 effector memory T cells with clonal features consistent with antigen-driven responses. Spatial mapping revealed complement activation and lipid-programmed myeloid states converging at sites of MN loss and TDP-43 pathology. Together, these findings connect peripheral and central immune alterations to ALS heterogeneity and highlight stratified immunomodulation as a potential therapeutic strategy.\n\nID: 42135338\nTitle: Generation of spinal cord organoids from human induced pluripotent stem cells caudalised to a lumbar fate.\nAbstract: Organoids offer a powerful platform to model human development and disease in vitro, while preserving key features of in vivo tissue architecture and complexity. In this study, we developed a protocol to generate human induced pluripotent stem cell (iPSC)-derived spinal cord organoids patterned to the lumbar region. Through immunofluorescent labelling and single-cell RNA sequencing analyses of these lumbar spinal cord organoids, we identified an enriched neuronal population complemented by a diverse array of glial subtypes that successfully recapitulate the ventral spinal cord, demonstrating greater anatomical relevance than conventional 2D motor neuron cultures. Notably, these organoids displayed functional neuronal properties, including spontaneous activity, indicative of integrated neural networks. This spinal cord organoid platform provides a physiologically relevant model for investigating human spinal cord development and presents a promising tool for studying neurodegenerative diseases and spinal cord injury in a controlled, human-specific context.\n\nID: 42132922\nTitle: \"Membrane-Guided\" Repair Strategy: Precision Delivery of GGT1 Degrader for Targeted Repair and Regeneration of Spinal Cord Neurons.\nAbstract: Ferroptosis is one of the important mechanisms of secondary neuronal death after spinal cord injury (SCI). However, the upstream regulators that could be targeted for therapeutic intervention remain poorly defined. This study identifies gamma-glutamyl transferase 1 (GGT1) as a key driver of ferroptosis, upregulated in neurons post-SCI. Screening a 150-compound natural product library, we discovered Enocyanin (EA), which reduced GGT1 protein levels, protected neurons from hypoxic injury, and exhibited anti-ferroptotic effects. Mechanistically, EA promoted GGT1 degradation through the E3 ligase MGRN1, leading to K48-linked polyubiquitination and proteasomal clearance, halting ferroptosis. To improve EA's stability and delivery, we engineered a biomimetic nanoplatform (NSCm@EA) using neural stem cell membranes, enhancing drug accumulation at the injured spinal cord. At single-cell resolution, NSCm@EA was shown to precisely remodel neuronal subpopulations, selectively expanding \u03b3-motor neurons and upregulating synaptic genes such as Gria2 and Negr1, while suppressing inflammatory and oxidative stress pathways. In summary, this study reveals GGT1's role in ferroptosis, identifies a natural product that induces its ubiquitin-mediated degradation, and presents a targeted biomimetic delivery strategy for precise intervention in spinal cord injury.\n\nID: 42131110\nTitle: Single cell Raman spectroscopic profiles predict treatment responses in patients with de novo acute myeloid leukemia.\nAbstract: Leukemia is a clonal malignant proliferative disease originating from hematopoietic stem cells. Although its treatment strategy has gradually developed from traditional chemotherapy to a multimodal treatment system including novel targeted therapy and immunotherapy, primary drug resistance in particular remains the core clinical problem leading to poor patient prognosis. This clinical dilemma indicates that the traditional genotyping system based on genomics has not been able to fully resolve the molecular heterogeneity of acute myeloid leukemia (AML), and it is urgent to establish a precise stratified model that can dynamically reflect the functional status of tumor cells in the initial stage of treatment. In this study, Raman spectroscopy (RS) combined with machine learning algorithm was used to construct a metabolic prognosis prediction model for AML chemotherapy response. Bone marrow single cell Raman spectroscopy data of newly diagnosed AML patients were collected, and the molecular fingerprint was analyzed by principal component analysis linear discriminant analysis (PCA-LDA) and multivariate curve resolute alternating least square method (MCR-ALS). The results showed that the PCALDA model achieved complete remission or non-remission (CR/NR) classification through 24 principal components (cumulative variance contribution of 90.1%), the accuracy of external validation was 94.8% (sensitivity 97.9%, specificity 92.0%), and the AUC reached 96.27%. Protein, lipid, nucleic acid and mixed components were decomposed by MCR-ALS, and lipid and nucleic acid metabolic pathways were enriched in NR group (P < 0.001). Studies have shown that RS single-cell metabolic fingerprint can decode the metabolic reprogramming features associated with chemotherapy resistance in AML, providing a new marker-free and highly sensitive tool for real-time prognostic stratification and targeted intervention.\n\nID: 42123994\nTitle: Long-Chain Fatty Acids as Drivers of Neuroinflammation in Neurodegeneration: Mechanistic Links to Lipid Peroxidation, Ferroptosis, and Mitochondrial Dysfunction.\nAbstract: Background: Neurodegenerative diseases (NDs) are mainly considered disorders marked by severe immunometabolic imbalance, characterized by ongoing neuroinflammation and glial activation. While mitochondrial dysfunction and oxidative stress are well-known features, the upstream metabolic factors linking these pathological processes remain poorly understood. Methods: In this review, we examined recent preclinical and clinical studies exploring the connections between lipid metabolism, glial immunometabolism, and regulated cell death pathways. Our focus was on how long-chain fatty acids (LCFAs) facilitate communication among mitochondria, reactive oxygen species (ROS), and ferroptosis in Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS). Results: New evidence shifts LCFAs from merely being passive indicators of cellular damage to active, upstream regulators of the neuroimmune response. Existing research shows that excess LCFA intake can overload astrocytic mitochondrial oxidative phosphorylation, leading to abnormal lipid droplet buildup and reactive astrogliosis. This lipid-driven reactivity promotes microglial polarization toward a persistent pro-inflammatory state. Notably, high levels of specific LCFAs, especially arachidonic acid, increase ROS production and lipid peroxidation. This lipotoxic environment ultimately triggers ferroptosis, an iron-dependent form of cell death shared across multiple NDs. Conclusions: The harmful interaction among mitochondrial dysfunction, lipid peroxidation, and ferroptosis is driven by an imbalance in LCFA levels. Addressing current challenges, such as the complex effects of polyunsaturated fatty acid supplementation, requires advanced techniques like single-cell multi-omics and artificial intelligence. Understanding this intricate lipidomic-transcriptomic crosstalk is crucial for moving toward personalized neuroimmunometabolism and developing new treatments to prevent ferroptosis.\n\nID: 42118343\nTitle: Modeling human neurodegenerative disorders in Drosophila: strategies and translational opportunities.\nAbstract: Drosophila melanogaster provides a genetically tractable and evolutionarily conserved platform for interrogating mechanisms of human neurodegeneration. This revised review critically evaluates how transgenic and genome-edited fly models expressing amyloid-beta, tau, alpha-synuclein, mutant huntingtin, and patient-relevant variants reproduce selective aspects of Alzheimer's disease, Parkinson's disease, and polyglutamine disorders, while also highlighting the boundaries of translational inference. We emphasize conserved pathogenic modules, including oxidative stress, mitochondrial dysfunction, impaired proteostasis, and stress signaling through Nrf2, JNK, and PINK1/Parkin, and distinguish robust mechanistic insights from findings that are primarily descriptive or overexpression-driven. We further discuss the specific contribution of Drosophila genetic tools such as GAL4/UAS, RNA interference, CRISPR-Cas9, and FLP/FRT-based mosaic analysis for dissecting cell-autonomous and non-cell-autonomous neurotoxicity. To improve usability, the manuscript now summarizes major disease models and natural compounds in dedicated tables, expands therapeutic discussion to include HDAC inhibitors and mitochondria/redox-directed small molecules, and outlines how fly studies can function within translational pipelines for variant interpretation, target prioritization, and preclinical triage before mammalian validation and human trials. Finally, we address key limitations of Drosophila relative to humans, including differences in metabolism, blood-brain barrier properties, immune complexity, and disease timescale, to provide a more balanced framework for using fly neurodegeneration models in precision medicine.\n\nID: 42359165\nTitle: Therapeutic frontiers in ALS: iPSC-based drug discovery, cell therapy, and gene therapy-Advances through 2026.\nAbstract: Three converging therapeutic paradigms-iPSC-based drug discovery, cell transplantation, and gene therapy-have substantially expanded the therapeutic pipeline for amyotrophic lateral sclerosis (ALS) between 2020 and 2026. The FDA's accelerated approval of tofersen (Qalsody) in April 2023 marked the first treatment targeting a genetic cause of ALS. iPSC-derived drug candidates, including ropinirole and bosutinib, have completed early-phase clinical trials led by Japanese institutions. Cell therapies targeting neuroinflammation through regulatory T cells are being actively explored as immunomodulatory strategies, although efficacy remains to be established in adequately powered trials. Next-generation gene-silencing approaches-including RNA interference (RNAi) therapeutics and AAV-delivered microRNA-entered first-in-human trials in 2024-2025. The identification of STMN2 as a downstream target of TDP-43 dysfunction has opened a potential TDP-43-downstream nucleic acid therapeutic avenue for sporadic ALS, which constitutes approximately 90% of all cases, with company-reported interim data suggesting target engagement in the ongoing Phase 1/2 ANQUR trial (QRL-201). This review synthesizes the latest evidence across all three therapeutic domains, with attention to the hierarchy of evidence, regulatory milestones, and the pioneering contributions of Japanese research groups.\n\nID: 42189263\nTitle: Identification of prognostic biomarkers in a large cohort of patients with LGMD R2.\nAbstract: Limb-girdle muscular dystrophy R2-dysferlin related (LGMD-R2) is a progressive muscle condition with marked variability in disease course, making prognosis challenging. Quantitative MRI (qMRI) has emerged as a complementary tool that may detect progression earlier and more precisely. Integrating different data modalities is challenging with conventional approaches, and artificial intelligence (AI) can help overcome this. Our aim is to develop robust models capable of predicting clinical progression in LGMD-R2 by incorporating AI-based techniques into the analysis pipeline. Data from 188 COS 1 participants were analysed. Disease progression was assessed using the North Star Assessment for Limb Girdle type Muscular Dystrophies (NSAD). Ambulatory individuals with a maximum NSAD\u2009\u2265\u200920 were included, and progression trajectories were identified through hierarchical clustering. Feature selection was performed using a machine learning pipeline, and top predictors were entered into stepwise logistic regression to build clinical-only and combined clinical-MRI models. Two stages of progression were identified, a fast one with a mean three-year loss of 14.4 NSAD points, and a moderate one, with a mean loss of 3.8 NSAD points. The combined model achieved better balanced accuracy than the clinical-only one (83.7% vs 78.7%). Key predictors in the combined model were disease duration and fat content measures in the anterior thigh and gracilis muscle, while the clinical model included disease duration, creatine phosphokinase (CK), and 10 m walk/run test velocity. Progression in LGMD-R2 can be grouped into distinct clinical trajectories. Individuals at a faster stage of progression were younger, had shorter disease duration, higher CK, greater weakness, and relatively preserved vastus intermedius and gracilis muscles. AI enabled efficient integration of heterogeneous data, and qMRI biomarkers provided complementary information that improved predictive accuracy.\n\nID: 42187024\nTitle: Systemic delivery of synapsin-promoted caveolin-1 overexpression ameliorates pathological TDP-43-induced cognitive decline and neurodegenerative changes.\nAbstract: Transactive response DNA-binding protein 43 (TDP-43) proteinopathy is associated with frontotemporal dementia and Alzheimer's disease (AD). We previously demonstrated that synapsin-promoted caveolin-1 (SynCav1) preserves cognitive function in the mouse model of AD. This study investigated the therapeutic potential of SynCav1 in a mouse model of TDP-43 proteinopathy. AAV-PhP.eB-SynCav1 was delivered systemically to the TDP-43A315T mouse, followed by cognitive evaluation and biochemical and ultrastructural analysis of brain tissue. SynCav1 exerted robust neuroprotective effects on cognition. Mechanistically, pathological TDP-43 mislocalized to membrane lipid rafts (MLRs), resulting in decreased MLR-associated GluN2A expression and degenerative changes in neuronal ultrastructure. In contrast, SynCav1 delivery alleviated TDP-43 mislocalization on MLRs, stabilized MLR-associated GluN2A expression, and preserved synaptic ultrastructure. Furthermore, SynCav1 mitigated TDP-43-induced mitochondrial hyper-fragmentation and excessive mitochondrial fission signaling. These findings establish a novel link between TDP-43 proteinopathy and MLR instability, supporting SynCav1 as a \"neuron-centric\" candidate for treating TDP-43-related neurodegeneration.\n\nID: 42182497\nTitle: WATER reveals heterochrony of molecular programs underlies developmental failure caused by minor spliceosome inhibition.\nAbstract: The final limb structure reflects coordinated deployment of molecular programs, defined not only by which genes are expressed but when they are activated and silenced across time. Existing omics analyses obscure the temporal unfolding of these programs and conflate program identity with deployment timing by assuming temporal equivalence between conditions. We developed WATER (Weighted Windowed Assignment of Temporal Expression of RNA), a framework that reconstructs temporal gene expression trajectories independently within each condition, enabling direct comparison of temporal program architecture between wild-type and perturbed systems. Applying WATER to U11-null mouse forelimb development revealed that minor spliceosome inhibition redistributes genes across inappropriate temporal trajectories. Minor spliceosome inhibition causes splicing defects in minor intron-containing genes such as the PRC2 component Eed, leading to reduced H3K27me3 deposition and chromatin-transcription divergence. Single-cell RNA sequencing revealed persistence of progenitor states, impaired chondrogenic progression, and p53-dependent apoptotic checkpoint activation. Orthogonal WATER analysis of Eed-knockout stem cells recapitulated key features of chromatin gating failure, including temporal redistribution of skeletal development programs and progenitor state persistence, confirming that Eed loss alone is sufficient to produce temporal program redistribution independently of other splicing defects. Trp53 ablation in U11-null limbs partially rescued distal limb structures without correcting the underlying splicing defects, establishing that checkpoint activation amplifies rather than initiates the timing disruption. The limb retains much of its molecular toolkit but executes it in the wrong order, demonstrating that developmental failure arises from mistimed deployment of intact molecular programs. Thus, temporal program architecture is a fundamental organizing principle of morphogenesis.\n\nID: 42086533\nTitle: Proteasomal-dependent CHK1 degradation leads to DNA damage accumulation in ALS cellular model systems.\nAbstract: Amyotrophic lateral sclerosis (ALS) is characterised by the aggregation of TDP-43 and mutant FUS in the cytoplasm of affected motor neurons. Accumulation of DNA damage is emerging as a novel correlative trait of ALS. We recently showed that formation of TDP-43 and FUS cytoplasmic inclusions (CIs) lead to DNA damage accumulation through dysregulation of the DNA damage response (DDR). However, the multiple molecular mechanisms contributing to DNA damage accumulation in affected motor neurons in ALS have not been fully elucidated. In recent years, chemical inhibition of the serine/threonine kinase CHK1 was shown to lead to accumulation of DNA breaks as well as increased apoptosis, in differentiated cortical neurons. Notably, CHK1 has been involved in DNA double-strand break repair in non-dividing cells, by acting through the histone chaperone ASF1A. In this article, we show that cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A. We observe CHK1 protein downregulation in neuronal cell lines, as well as in patient-derived motor neurons progenitors and in the spinal cord of a FUS-ALS mouse model. Restoration of the nuclear levels of CHK1 and ASF1A via transient overexpression, is sufficient to reduce DNA damage signal accumulation and rescues DDR defects. Importantly, we show that the ubiquitin-proteasome pathway is responsible for CHK1 degradation in cells bearing FUS CI, since its inhibition restores CHK1 and ASF1A protein levels. Our study demonstrates that proteasomal-dependent CHK1 and ASF1A downregulation contributes to accumulation of DNA damage in cells affected by ALS-linked protein aggregates.\n\nID: 42083963\nTitle: Advances in Microneedle Technology for Targeted Therapy in Alzheimer's and Parkinson's Disease.\nAbstract: The fourth major cause of death worldwide is Neurodegenerative Diseases (NDs), including Alzheimer's and Parkinson's disease. The existing therapies have only a small effect on alleviating symptoms, mainly because the therapeutic agents are difficult to cross the bloodbrain barrier. The purpose of the review is to discuss the potential of microneedle-based transdermal delivery systems to improve the delivery of drugs to the central nervous system and thereby manage neurodegenerative diseases effectively. The article summarizes and synthesizes the available literature that targets the strategies of microneedle-mediated drug delivery. The literature on the design, composition, pharmacokinetics, and mechanistic benefits of different microneedle platforms for surmounting central nervous system barriers was identified and thematically synthesized. Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier. Micro-needles can be used to deliver small molecules, peptides, and nanoparticles to the brain, thereby avoiding systemic side effects and enhancing drug bioavailability. Some of those designs include dissolving, coated, hollow, hydrogel-forming, and stimuli-responsive microneedles, which have been shown to target the brain and exhibit higher therapeutic efficiency in preclinical models. Although technological advances have improved, the clinical translation of microneedlebased strategies remains limited. The future directions could include using microneedles with stem cell-based therapies, CRISPR/Cas9 gene editing, artificial intelligence-based delivery systems, and responsive release technology to facilitate customized treatment. The Microneedle-based drug delivery systems are promising in overcoming the current limitations in the treatment of neurodegenerative diseases. Nonetheless, a large-scale clinical validation is necessary to guarantee safety, efficacy, and scalability to be applied to real-life scenarios.\n\nID: 42013476\nTitle: Cryptic Splicing in ALS: From Driving Disease Progression to Unlocking Novel Therapeutics.\nAbstract: TDP-43 is an RNA-binding protein that regulates multiple aspects of RNA processing, and its mislocalization from the nucleus to the cytoplasm is a defining feature of amyotrophic lateral sclerosis (ALS). While both loss- and gain-of-function mechanisms contribute to disease, the discovery of cryptic splicing has shed light on the downstream consequences of TDP-43 nuclear clearance for neuronal health. Here, we highlight how loss of nuclear TDP-43 can drive a cascade of events that lead to the impairment of cellular proteostasis and result in a positive feedback loop that perpetuates neuronal dysfunction. This sustains the appearance of cryptic splicing events in genes that are involved in key pathways for the maintenance of axonal homeostasis and synaptic transmission. In contrast to their detrimental effects on neuronal health, cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies.\n\nID: 42003777\nTitle: TRMT6-Mediated m1A Modification of CDK9 mRNA Is a Dual-Pronged Pathogenic Driver for HBV-Related Hepatocellular Carcinoma.\nAbstract: Hepatocellular carcinoma (HCC) is a leading cause of death worldwide, with hepatitis B virus (HBV) infection being the major risk factor. Dysregulation of mRNA methylation contributes to tumorigenesis and virus replication. However, the association of N1-methyladenosine (m1A) modification with HCC progression and HBV replication remains unclear. Here, single-nucleus RNA sequencing (snRNA-seq) of 4 HCC and 7 adjacent tissues (2 from this study and 5 from the GSE242889) revealed elevated mRNA methylation in HCCs, with increased expression of m1A \"writers\" and \"readers\" and decreased expression of m1A \"erasers\". Among them, m1A writer TRMT6 was up-regulated in HCC and correlated with poor patient prognosis. TRMT6 knockdown strikingly restrained the malignant phenotypes and tumorigenicity of HCC cells as well as HBV replication. Mechanistically, TRMT6-mediated m1A modification enhanced the stability and translation efficiency of cyclin-dependent kinase 9 (CDK9) mRNA. Elevated CDK9 facilitated HCC progression by up-regulating its downstream oncogenic effectors, and stimulated HBV replication via TARDBP phosphorylation at Ser254 to enhance pgRNA transcription and repress pgRNA splicing. CDK9 inhibitor FIT-039 abrogated these effects without obvious toxicity. Thus, TRMT6-mediated m1A modification dually drives HCC malignancy and HBV replication, representing a promising therapeutic target, and CDK9 inhibition may constitute an effective strategy for HBV-related HCC.\n\nID: 42000856\nTitle: Beneficial bystander-enhanced cryptic splice rescue of cardiac-type Fabry GLA IVS4+919G>A by adenine base editing in patient fibroblasts.\nAbstract: The IVS4+919G>A mutation in the GLA gene, prevalent in East Asian populations, causes cardiac-type Fabry disease by creating an abnormal splice site. This results in the insertion of a 57-nucleotide segment between exon 4 and exon 5, introducing a premature stop codon and leading to a truncated, non-functional \u03b1-Gal A protein. We evaluated whether adenine base editing (ABEmax) can modulate this allele-induced cryptic splice event in patient-derived fibroblasts in vitro as a proof-of-concept. Two ABEmax/sgRNA constructs targeting intron 4 (ABEmax-sgRNA1 and ABEmax-sgRNA2) were tested; both induced on-target +919\u2009A\u2009\u2192\u2009G conversion with frequent bystander edits at +918/+920. Edited bulk populations and single-cell-derived clones showed restoration of correctly spliced GLA mRNA with reduced aberrant transcripts, increased GLA protein, higher \u03b1-Gal A activity (approaching wild-type levels in some clones), and reduced intracellular Gb3 signal. A focused next-generation sequencing panel identified a low-frequency intronic change at one predicted off-target locus without predicted coding consequences. These findings demonstrate in vitro splice rescue of a deep intronic, cardiac-type Fabry disease variant by adenine base editing and suggest that bystander edits in non-coding sequence can further enhance correction by suppressing cryptic splicing, with concordant improvements in \u03b1-Gal A activity and Gb3 signals.\n\nID: 41964251\nTitle: RNA G-quadruplex-protein interactions: from nuclear RNA processing to cytoplasmic stress response and neurodegeneration.\nAbstract: RNA G-quadruplexes (rG4s) are stable secondary structures formed by non-canonical Hoogsteen base-pairing of guanine-rich sequences in precursor and mature messenger and non-coding RNAs. We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology. We discuss the implications of a dynamic equilibrium of folded and unfolded rG4s in health and disease, with particular focus on their emerging roles in neurodegeneration.\n\nID: 41910152\nTitle: Stimuli-responsive mesoporous silica nanoparticles for brain tumor theranostics and drug targeting.\nAbstract: Designing a delivery system to target a drug to brain tumors (BT) is a complex process. Drug delivery to BT presents a plethora of obstacles, such as poor bioavailability, drug targeting and its efficacy due to the complexity of the brain's structure, anatomy, and implications of the blood-brain barrier's (BBB) functionality. The anatomical complexity of the brain limits other conventional modes, viz., radiation and major surgery. Moreover, the conventional chemotherapeutics, including radiation therapy for BTs, develop drug resistance and can cause complications further. This review presents how nanotechnology-based drug delivery systems address these limitations when the drug is administered in a conventional mode. Liposomes, specialized nanoparticles (NPs) (nanoparticulate systems fabricated from polymers and gold), and dendrimers, other nanotechnology-driven carriers, were targeted for BT delivery. Nonetheless, their safety aspects, such as systemic toxicity, off-target effects of therapeutic agents, effective BBB permeability, and drug targeting, are elaborated. Mesoporous silica nanoparticles (MSNs) offer specialized delivery with the potential of drug targeting directly to BTs via their mesoporous structure, extensive surface area, and adjustable pore size, drug-loading and stimuli-triggered responsiveness. Targeting ligands via surface functionalization enhances the tumor-targeting attributes of MSN modalities while reducing systemic toxicity and off-target effects. To ensure calibrated dosing of anticancer drugs triggered through biophysical response, MSNs can respond to such biophysical or biochemical stimuli originating from the tumor microenvironment (TME). Novel modalities of MSN, previously considered as ineffective owing to BBB restrictions, offer gene-editing tools, small-interfering RNA (siRNA) and further advancement. Clinical oncology, molecular biology, and nanotechnology concordantly develop novel treatment avenues that could significantly modulates desired potential for BT patients. MSNs are regarded as effective nanocarriers targeting a drug to TME, as elaborated in this review, providing impetus to drug delivery, surface modifiability, and stimuli-triggered mechanisms, including both endogenous and exogenous stimuli. MSNs are novel nanocarrier systems with drug targeting potential to brain tumors (BTs).Stimuli-triggered MSNs are investigated in the BTs, focused on pH-responsiveness.Advanced MSN-based nanocarrier systems can effectively deliver the drug across the BBB.\n\nID: 41909467\nTitle: Exosome-like nanovesicles from acerola for CRISPR-Cas9 ribonucleoprotein delivery to the central nervous system.\nAbstract: An aberrant six-base repeat in intron 1 of C9orf72 is the most frequent cause of solitary and familial amyotrophic lateral sclerosis and frontotemporal dementia. This mutation is a potential target for CRISPR/Cas9-based genome editing. However, the blood-brain barrier and limitations of current viral or nanoparticle-based delivery systems to neurons significantly restrict the clinical application of CRISPR-Cas9 in the brain. To address these challenges, we developed a drug delivery system using acerola-derived exosome-like nanoparticles (AELNs), which may overcome several limitations associated with human exosomes. AELNs stably form complexes with ribonucleoproteins (RNPs) comprised of Cas9 proteins and guide RNAs (gRNAs). We improved the delivery efficiency and selectivity of AELN/RNP complexes in GLP2-receptor-expressing neurons by incorporating GLP2 peptides into the AELN/RNP complexes. Intranasal administration of peptide-tagged AELN/RNP complexes in vivo confirmed the successful genome editing of C9orf72, demonstrating the potential of this system for treating neurodegenerative diseases. This study presents a potentially innovative approach for in vivo genome editing using a noninvasive delivery system.\n\nID: 41904011\nTitle: The quest to restore neuronal structure: Targeting cytoskeletal proteins in neurodegenerative diseases.\nAbstract: Neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis (ALS), and Huntington's disease are characterized by progressive neuronal dysfunction and loss. A growing body of evidence implicates cytoskeletal disruption as a central pathological mechanism in these conditions. Cytoskeletal proteins, including microtubules, actin filaments, tau, neurofilaments, and alpha-synuclein, not only provide structural integrity but also regulate axonal transport, synaptic connectivity, and neuroplasticity. Its dysfunction will lead to impaired intracellular trafficking, protein aggregation, and neuronal degeneration. This chapter explores clearly about the specific cytoskeletal abnormalities that are evident in major neurodegenerative disorders, highlighting the biological mechanisms such as tauopathy-induced microtubule instability in Alzheimer's, actin cytoskeleton dysregulation in Parkinson's, and neurofilament aggregation in ALS. Current therapeutic strategies aimed at the stabilizing cytoskeletal components, enhancing protein clearance, and restoring transport dynamics are examined, alongside the cutting-edge approaches including the gene therapy, CRISPR/Cas9 editing, and nanotechnology-based delivery systems. Challenges such as limited blood-brain barrier penetration, off-target toxicity, and patient heterogeneity are also discussed with the focus on need for precision medicine. Additionally, we have also explored the future directions that specifically focused on the biomarker development, combination therapies, and strategies to promote neuroregeneration and structural plasticity. Targeting cytoskeletal pathways holds significant promise not only for suppressing the disease progression but also for rebuilding the structural foundation of the nervous system, potentially reversing the neurodegenerative decline.\n\nID: 41890591\nTitle: Axonal transport impairment as an upstream mechanism in amyotrophic lateral sclerosis pathogenesis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive loss of upper and lower motor neurons. Despite marked genetic and pathological heterogeneity, a unifying pathogenic framework remains lacking. We propose that axonal transport impairment represents an early and convergent but genotype-modulated upstream vulnerability in ALS, contributing to distal synaptic failure, bioenergetic stress, protein aggregation, neuroinflammation, and neuronal death. Across many ALS models, including SOD1, TARDBP (TDP-43), FUS, and C9orf72, transport deficits are frequently detectable in presymptomatic stages, often preceding overt motor neuron loss or clinical manifestation, although temporal ordering varies by molecular subtype. Human data from induced pluripotent stem cell-derived motor neurons and neuroimaging in mutation carriers further support early transport dysfunction in both familial and sporadic ALS. We synthesize genetic, cellular, and systems-level evidence demonstrating that diverse ALS-associated mutations converge on intracellular trafficking machinery through distinct but interacting mechanisms, disrupting long-range cargo delivery and clearance in motor neurons. This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation. This model generates testable predictions regarding presymptomatic transport biomarkers and the timing of therapeutic intervention. We discuss implications for biomarker development and therapeutic strategy, proposing restoration of axonal transport as a central component of rational multimodal disease modification in ALS.\n\nID: 41883703\nTitle: The Genetics of TDP-43 Type C Neurodegeneration: A Whole-Genome Sequencing Study and Literature Review.\nAbstract: Frontotemporal lobar degeneration TDP43 type C (TDP-C) is a rare and unique neurodegenerative disease that attacks the anterior temporal lobe. Recently, it was shown that Annexin-A11 and TDP-43 coaggregate specifically in TDP-C. Current literature on the genetic associations with TDP-C, reviewed here, lacks a discernible corpus of robust or replicated findings. In this study, using blood tissue, we completed whole genome sequencing to investigate ANXA11 and TARDBP genetic variants for their association with TDP-C. Then, we completed genome-wide hypothesis-free analyses using artificial intelligence to identify rare pathogenic variants associated with TDP-C. (1) We tested common variants in ANXA11 and TARDBP for their association with 37 TDP-C cases vs 290 controls. We attempted to replicate our findings in a different cohort of 467 TDP-C cases vs 3,153 controls and contrasted them with cohorts of TDP-A and TDP-B. (2) AI-guided analyses were completed to prioritize pathogenic rare variants associated with TDP-C in our cohort. (1) Four common variants in ANXA11 (rs113772135, rs2789686, rs1079242, rs61860017) were significantly associated with TDP-C in the discovery cohort and replicated in the other cohort of TDP-C but not in TDP-A or TDP-B, providing evidence for ANXA11 specific association with TDP-C. Rs1079242-A showed the most robust replication (p = 7.35 \u00d7 10-05) and correlates with higher ANXA11 level in CSF (p = 4 \u00d7 10-11). No associations were found between TARDBP and TDP-C (p > 0.05). Using AI-guided rare variant analyses, we identified a pathogenic variant in FIG4, a gene that has been implicated in amyotrophic lateral sclerosis (ALS). Because of the observed potential genetic overlap between some ALS genes and TDP-C, we leveraged mendelian randomization and found that ALS genetic load is associated with TDP-C risk (p = 0.0046). This study provides replicated evidence for the association between common variants in ANXA11 with TDP-C. Knowing rs1079242-A affects ANXA11 level in CSF, future studies may aim to investigate ANXA11 level as potential CSF biomarker for TDP-C. Moreover, FIG4 and ANXA11 have been implicated in the inositol pathway. Our results provide novel insights into the genetic risk of TDP-C and offer new clues about its underpinning mechanisms.\n\nID: 41865126\nTitle: Recent Advances in the Non-viral Delivery of Genes to Central Nervous System Disorders.\nAbstract: Disorders of the central nervous system (CNS), neurological disorders, neurodegenerative disorders, genetic disorders) constitute a significant burden on global health, and current treatment options remain challenging. As treatment for CNS disorders is primarily palliative, the underlying causes of disease progression are not addressed through conventional pharmacologic therapies. Gene therapy has the potential to address these root causes of disease progression; however, many of the vectors used in gene therapy (e.g., adeno-associated viruses (AAVs)) have limitations such as immunogenicity, low cargo capacity, and crossing the blood-brain barrier (BBB). These limitations have led to significant progress in the development of non-viral gene delivery systems. Compared with viral vectors, non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration. This review reports recent advancements in the development of non-viral platforms for CNS gene delivery and focuses on lipid-based nanoparticles, polymeric nanoparticles, exosome-based techniques, and new hybrid technologies. Particular emphasis is placed on nanoparticle modification approaches to enhance BBB penetration and enable delivery of genome-editing technologies (CRISPR/Cas systems). The review provides explanations of clinical trials, regulatory considerations, and manufacturing issues that result from the recent developments noted above. It also explores the emerging role of artificial intelligence in supporting carrier design and enhancing delivery efficiency. Both artificial intelligence and non-viral platforms have the potential to facilitate the advancement of safe, effective, and repeatably administered gene therapies for patients with CNS disorders.\n\nID: 41864145\nTitle: Emerging disease-modifying therapies for Angelman syndrome: A comprehensive review for pediatric neurologists.\nAbstract: Angelman syndrome (AS), a rare neurogenetic disorder affecting approximately 1 in 15,000 live births, results from loss of functional UBE3A gene expression and manifests with severe developmental delay, intellectual disability, absent speech, ataxia, epilepsy, and distinctive behavioral features. Until recently, only symptomatic management was available. This review provides pediatric neurologists with a comprehensive, practice-oriented overview of emerging disease-modifying therapies for AS, focusing on therapeutic approaches advancing through clinical development. The molecular pathophysiology of AS, natural history considerations critical for trial interpretation, and the current evidence for antisense oligonucleotide (ASO) therapies (ION582, GTX-102/apazunersen, rugonersen), gene replacement approaches (MVX-220), and next-generation strategies including CRISPR-based gene editing, artificial transcription factors, small molecules, and novel delivery platforms are reviewed. ASO therapies targeting the UBE3A antisense transcript represent the most clinically advanced approach, with three candidates showing proof-of-concept efficacy in Phase 1/2 studies and two advancing to pivotal Phase 3 trials. Gene replacement therapy offers potential single-administration treatment but faces challenges regarding safety, immune responses, and durability. Next-generation approaches including CRISPR activation, epigenetic editing, and blood-brain barrier-penetrating delivery systems show preclinical promise. Critical challenges include outcome measurement limitations, genotype stratification, long-term safety monitoring, and ensuring equitable access. These advances herald a transformation in AS clinical care and represent a milestone in precision pediatric neurology.\n\nID: 41863273\nTitle: PROTAC-Based Therapeutics: From Design to Clinical Potential in Neurodegenerative Disease.\nAbstract: Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and ALS, are characterized by a progressive loss of neuronal function and a direct correlation between their progression and proteins with misfolded and aggregated structures. Although significant efforts have been made, and various therapies are available for their treatment, they show only a modest beneficial response to their progression. The main reasons for this phenomenon can be correlated with a loss of target specificity, low permeability in crossing the BBB, and their ineffectiveness in clearing proteins from neurons. Within this therapeutic paradigm, proteolysis-targeting chimaeras, or PROTACS, have been identified as a novel therapeutic strategy. Unlike traditional smallmolecule inhibitors, PROTACS take advantage of the natural ubiquitin proteasome system to specifically degrade target proteins. At a molecular level, PROTACS consist of a ligand that specifically recognizes a target protein, a linker, and an E3 ligand-recruiting ligand that specifically recruits an E3 ligase. At a therapeutic level, this offers the advantage of catalytic protein degradation that should allow for reduced dosing. Preclinical studies carried out using neurodegenerative disease models have shown the potential for selective targeting of major pathologic proteins, such as tau, \u03b1- synuclein, TDP-43, and mHTT, which are crucial for pathogenesis. In addition, developments in the formulation of brain-permeable PROTACS, understanding of E3 ligase expression levels in the central nervous system, and application of iPSC-derived neuronal systems have contributed to rapid developments in this area. Although pharmacokinetic modification and degradation-specific approaches are still required, evidence suggests a major therapeutic potential for PROTAC-based approaches for the treatment of neurodegenerative disorders.\n\nID: 41838122\nTitle: TDP-43 impairs glycolysis by sequestering hexokinase 1 in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron degeneration and cytoplasmic mislocalization of TDP-43. While metabolic dysfunction is increasingly recognized in ALS, the mechanistic link between impaired energy metabolism and TDP-43 pathology remains unknown. Here, we show that cytoplasmic TDP-43 directly disrupts glycolysis by targeting hexokinase 1 (HK1), the first rate-limiting enzyme of the pathway. In cells expressing a TDP-43 variant lacking its nuclear localization signal and in patient-derived iPSC motor neurons, TDP-43 accumulation in the cytoplasm reduces glycolytic capacity, indicating a neuron-intrinsic metabolic defect. Across cellular models including patient-derived neurons, TDP-43 mutant mice, and postmortem spinal cord tissue from ALS patients, we observe consistent decreases in HK1 protein level, mitochondrial association, and enzymatic activity, despite unchanged transcript levels. Mechanistically, cytoplasmic TDP-43 directly binds to HK1, disassociating it from mitochondria and promoting its sequestration into insoluble aggregates. This mislocalization impairs glycolysis and increases neuronal vulnerability. Notably, compensation for HK1 loss reduces cytoplasmic TDP-43 and ubiquitin accumulation, improves motor performance, and prolongs survival in TDP-43-associated ALS models. Together, these findings identify a previously unrecognized mechanism by which TDP-43 impairs glycolysis through HK1 misregulation and highlight glycolytic restoration as a potential therapeutic strategy in ALS.\n\nID: 41809005\nTitle: cGAS inhibition delays TDP-43-driven ALS Pathogenesis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder marked by motor neuron loss and cytoplasmic mislocalization of TAR DNA-binding protein 43 (TDP-43), a key regulator of RNA splicing. However, the upstream modulators of this process remain poorly defined. Here we identify cyclic GMP-AMP synthase (cGAS) as a central mediator of TDP-43 pathology and associated mis-splicing. cGAS expression was elevated in ALS patient brains and enriched across activated microglia. In human iPSC-derived microglia-motor neuron co-cultures, neuronal TDP-43 pathology triggered microglial cGAS activation, whereas pharmacological inhibition with a potent human cGAS inhibitor reduced phosphorylated TDP-43, restored lysosomal and phagocytic programs, normalized microglial reactivity, and reversed TDP-43-associated RNA splicing defects. In vivo, cGAS inhibition in TDP-43 Q331K mice reversed widespread RNA splicing abnormalities across neurons and oligodendrocyte lineage cells, attenuated neurodegenerative pathology, and preserved motor function. Together, these findings identify cGAS as a druggable upstream regulator linking innate immune signaling to TDP-43-dependent RNA mis-splicing and neurodegeneration, and establish cGAS inhibition as a promising therapeutic strategy for ALS.\n\nID: 41804798\nTitle: Cofilin hyperphosphorylation triggers TDP-43 pathology in sporadic amyotrophic lateral sclerosis.\nAbstract: Pathological forms of TAR-binding protein 43 (TDP-43), involving its aberrant mislocalization to the cytoplasm, inclusion formation, hyperphosphorylation and fragmentation, are present in \u223c45-50% frontotemporal dementia (FTD) and Alzheimer's disease individuals, and most (97%) amyotrophic lateral sclerosis (ALS) cases. Hence, identifying mechanisms that induce TDP-43 pathology are central to neurodegeneration and developing new therapeutic targets in these conditions. Cofilin is a multi-functional protein with a crucial role in regulating the actin cytoskeleton. Actin has important neuronal-specific activities in dendritic spines, axonal growth cones and synapses and it is in constant equilibrium between two forms: monomeric globular actin (G-actin) and polymeric filamentous actin (F-actin). Cofilin controls actin dynamics by depolymerising and severing actin filaments. When cofilin is phosphorylated (at Serine-3) by LIM kinase1 (LIMK1), it becomes inactive, leading to production of more F-actin. Defects in cofilin are well described in other neurodegenerative disorders, unlike in ALS. We examined phosphorylation of cofilin and actin dynamics in post-mortem spinal cord tissue from sporadic ALS (SALS) patients, the TDP-43 rNLS8 transgenic mouse model, and NSC34 motor neuronal cells expressing cytoplasmic TDP-43. F-actin was pharmacologically stabilized to mimic cofilin hyperphosphorylation, and TDP-43 pathology was assessed. Neuronal cells were treated with a non-phosphorylatable cofilin S3A peptide (MAAGVAVSDGVIKVFN), and TDP-43 pathology and apoptosis were evaluated. Here, we show that cofilin is hyper-phosphorylated in human ALS and disease models compared to controls. This was detected in spinal motor neurons from sporadic ALS (SALS) patients and a TDP-43 mouse model (rNLS8) displaying key ALS phenotypes, and in motor neuronal NSC34-cells expressing cytoplasmic TDP-43. Supporting this observation, more F-actin relative to G-actin was present in cortical/spinal cord lysates from SALS patients and TDP-43 rNLS8 mice, and NSC34-cells expressing TDP-43. We also show that mimicking cofilin hyperphosphorylation by pharmacological stabilization of F-actin induced TDP-43 pathology: cytoplasmic mislocalization, inclusion formation, hyperphosphorylation, and fragmentation, and promoted its recruitment into stress granules (SGs). Furthermore, we detected increased levels of LIMK1 phosphorylation and tropomyosin isoforms 4.1 and 4.2 in SALS patients. These findings reveal aberrant cofilin hyperphosphorylation disrupts actin dynamics, triggering TDP-43 pathology and SG recruitment in SALS. They imply that preventing cofilin phosphorylation is a novel therapeutic strategy applicable to most ALS cases. Treatment of neuronal cells with the S3A peptide prevented features of TDP-43 pathology and apoptosis compared to control peptides. These findings thus describe a novel pathogenic mechanism producing TDP-43 pathology, applicable to most ALS cases and other neurodegenerative diseases.\n\nID: 41796799\nTitle: RNA-binding proteins TDP-43 and FUS promote R-loop resolution and regulate transcription termination.\nAbstract: TDP-43 and FUS are RNA-binding proteins involved in the regulation of diverse RNA-processing events and have been strongly implicated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). We have previously demonstrated the role of symmetrical dimethylation (me2s) of a conserved arginine residue (R1810 in human POLR2A) in the C-terminal domain (CTD) of RNA polymerase II (RNAPII), which facilitates the recruitment of the Tudor domain-containing protein SMN to resolve R-loops at transcriptional termination sites. Here, we demonstrate that TDP-43 and FUS contribute to transcription termination through the R1810me2s-SMN pathway. Our data show that TDP-43-and to a lesser extent, FUS-are recruited to chromatin via this pathway, and that disruption of their recruitment leads to defective RNAPII termination. This impairment results in the accumulation of R-loops and elevated DNA damage to gene terminators. Using transcriptome-wide analyses, we further show that TDP-43 RNA-binding sites are highly correlated with regions of R-loop formation. Importantly, we find that the RNA-binding activity of TDP-43 is essential for its role in resolving R-loops and promoting efficient transcription termination. These findings establish a mechanistic link between TDP-43/FUS, R-loop resolution, and transcription termination, providing new insights into how their dysfunction may drive genome instability and contribute to the pathogenesis of ALS and FTD.\n\nID: 41788548\nTitle: Brain organoids as precision models for neurodegenerative diseases: from disease modeling to drug discovery.\nAbstract: Neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS) have become major global causes of disability and mortality. Their complex pathogenic mechanisms remain incompletely understood, and effective disease-modifying therapies are still lacking. Traditional animal models and two-dimensional (2D) cell culture systems exhibit notable limitations in structural complexity, human relevance, and translational validity, making it difficult to faithfully recapitulate human-specific neuropathology. In recent years, brain organoid technology derived from induced pluripotent stem cells (iPSCs) has advanced rapidly, enabling the self-organization of diverse neuronal and glial cell types within a three-dimensional (3D) architecture that partially mimics human brain development and disease-related pathological events. When integrated with CRISPR-Cas9-based genome editing and multi-omics profiling, organoids support causal mechanism studies, target validation, and individualized drug-response prediction, highlighting their growing value in early-stage drug discovery. Despite current challenges-including insufficient maturation, lack of vascularization and immune components, and batch variability-the continuous progress in bioengineering, microfluidic systems, and artificial intelligence (AI)-driven multimodal data analysis is steadily expanding the translational potential of organoids as human-relevant preclinical models. Overall, brain organoids provide an essential foundation for constructing physiologically relevant and predictive research platforms for neurodegenerative diseases, offering new opportunities for therapeutic development and precision medicine.\n\nID: 41772312\nTitle: Zinc finger proteins (ZFPs) in health and disease.\nAbstract: Zinc finger proteins (ZFPs), a vast superfamily of sequence-specific DNA and RNA-binding proteins, serve as master regulators of gene expression and cellular homeostasis. While traditionally studied for their roles in development, ZFPs have emerged as critical effectors and therapeutic targets across a wide spectrum of human pathologies, including cancer, neurological disorders, and autoimmune diseases. This review systematically dissects the molecular mechanisms by which dysregulated ZFP activity drives disease pathogenesis, using ischemic stroke as a central exemplar to illustrate their multifaceted roles. We detail how specific ZFPs orchestrate key stroke risk factors such as hypertension, hyperglycemia, and atherosclerosis, subsequently govern post-ischemic injury cascades, including neuroinflammation, programmed cell death, and blood-brain barrier disruption. Addressing the long-standing challenge of ZFPs as \"undruggable\" targets, we critically evaluate cutting-edge therapeutic strategies poised to modulate their function with precision. These include small-molecule modulators, targeted protein degraders (PROTACs), zinc finger nuclease (ZFN)-based gene editing, and advanced nanocarrier delivery systems, complemented by high-throughput computational screening. By integrating deep mechanistic insights with novel translational approaches, this review establishes a pioneering pan-disease framework for targeting ZFP networks. We provide a structured roadmap for future research and highlight the immense potential of ZFPs as a new class of master regulatory targets for developing novel and feasible therapies in ischemic stroke and beyond.\n\nID: 41763444\nTitle: Harnessing exosomes for precision diagnostics and therapies in psychiatry disorders.\nAbstract: Exosomes are nanosized extracellular vesicles enriched with proteins, lipids, and nucleic acids and are emerging as powerful mediators of intercellular communication with transformative potential for psychiatry. Their ability to cross the blood-brain barrier, reflect the molecular state of parent cells, and deliver functional cargo positions them as uniquely suited tools for precision diagnostics and targeted therapeutics in neuropsychiatric disorders. This narrative review synthesizes current advances in exosome biology, isolation technologies, and multi-omics profiling to evaluate their utility as biomarkers for early detection, disease stratification, and treatment monitoring across major psychiatric conditions, including depression, bipolar disorder, schizophrenia, and neurodevelopmental disorders. We further examine innovative therapeutic strategies leveraging engineered exosomes for targeted delivery of small molecules, RNA therapeutics, and gene-editing systems to neural circuits implicated in psychiatric pathophysiology. Key challenges such as standardization of isolation methods, cargo heterogeneity, and translational scalability are critically discussed alongside emerging solutions from nanotechnology and machine learning-driven biomarker discovery. By integrating mechanistic insights with translational applications, this review highlights exosomes as a promising frontier for precision psychiatry and outlines the roadmap needed to advance them toward clinical implementation.\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.

In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target.\n --- END ACTUAL ABSTRACT FOR 42178983 ---\n\n- ERROR: You cited ID: 42171861 for the quote: \"Recasting TDP-43 from neuropathological hallmark to immunoactive sentinel supports a shift from descriptive nosology to stratified immunotherapy.\"\n FACT: Strict Misquote Detected!

Upon nuclear clearance and mislocalisation, TDP-43 enters the periphery; acetylation shapes its conformation, trafficking and immunogenicity. This narrative review synthesises single-cell transcriptomics, proteomic immunoprofiling and clinical inflammatory phenotyping to examine whether site-specific acetylated TDP-43 species may be associated with peripheral inflammatory signatures relevant to ALS immunopathology. By integrating separate datasets on acetylated TDP-43, monocyte phenotypes and cytokine modules, we propose two provisional endotypes characterised by monocyte reprogramming, cytokine modules and Blood-Brain Barrier (BBB) dysfunction-each representing clinically actionable pathways. Framed as a provisional neuroimmune interface, the acetylation state is considered here as a plausible molecular correlate and potential therapeutic entry point: a measurable clue to inform pharmacological targeting and, potentially, a modifiable target via p300CREB-Binding Protein (CBP)-Histone Deacetylase (HDAC) axes or sirtuin activity. Recasting TDP-43 from neuropathological hallmark to immunoactive sentinel supports a shift from descriptive nosology to stratified immunotherapy, in which treatment allocation is informed by acetylation-defined peripheral signatures.\n --- END ACTUAL ABSTRACT FOR 42171861 ---\n\n- ERROR: You cited ID: 42409192 for the quote: \"Advanced CRISPR modalities... are evaluated for reversible and targeted modulation of disease-relevant gene networks.\"\n FACT: Ellipses (...) are strictly forbidden.

Current therapies are primarily symptomatic and have not consistently demonstrated prevention of disease progression. This review introduces Programmable gene modulation networks, a systems-level framework that integrates CRISPR/Cas technologies with nanotechnology-enabled brain delivery for precision intervention in Parkinson's disease. Advanced CRISPR modalities, including CRISPR interference, activation, base editing, prime editing, and epigenetic editing, are evaluated for reversible and targeted modulation of disease-relevant gene networks. Non-viral nanocarrier platforms, such as lipid nanoparticles, polymeric systems, and exosome-mimetic vesicles, are discussed for overcoming blood-brain barrier limitations and improving brain-specific delivery. The review further emphasizes translational challenges, including delivery efficiency, off-target effects, long-term safety, manufacturing scalability, and regulatory considerations. By integrating molecular network biology, programmable gene regulation, and translational decision-making, this review provides a roadmap for developing next-generation disease-modifying therapies for Parkinson's disease.\n --- END ACTUAL ABSTRACT FOR 42409192 ---\n\n- ERROR: You cited ID: 42108387 for the quote: \"Novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis.\"\n FACT: Strict Misquote Detected!

However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation. This comprehensive review compares various CRISPR-Cas9 delivery vectors, viral, nonviral and physical, with a focus on their efficacy in neurological diseases such as AD. Viral vectors viz., adeno-associated viruses (AAVs) and lentiviruses (LVs) demonstrate high transduction efficiency and BBB permeability. AAVs are preferred for their low immunogenicity, minimal toxicity, high neuronal tropism and episomal persistence, enabling sustained expression without insertional mutagenesis. LVs offer larger genetic payloads but raise concerns about genomic integration and potential oncogenesis, though integration-defective variants mitigate these risks. Nonviral vectors, including peptide and polymer-based nanoparticles, lipid nanoparticles (LNPs) and Inorganic carriers such as gold and silver nanoparticles, are less immunogenic and easier to handle but require further optimisation for in\u00a0vivo BBB crossing and endosomal escape. Physical methods such as electroporation and microinjection are suitable for in\u00a0vitro/ex vivo use, while novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis. These preclinical studies show that these technologies can successfully edit genes and provide therapeutic benefits, including amyloid reduction and cognitive improvement in AD models. Yet off-target effects, immune responses and regulatory hurdles persist. Overall, continuous innovation in delivery vector design and safety profile-targeting strategies is crucial for advancing CRISPR-Cas9 towards clinical therapies for AD-based therapies and related neurological disorders.\n --- END ACTUAL ABSTRACT FOR 42108387 ---\n\n- ERROR: You cited ID: 42415876 for the quote: \"Recent advances in nanomaterials have enabled LNDDSs not only to transport therapeutic agents across systemic biological barriers but also to selectively destabilize plasma and organelle membranes.\"\n FACT: Strict Misquote Detected!

Their applications have rapidly expanded with several tissue targeting formulations in early-phase clinical trials. Beyond small molecular drugs, LNDDSs are increasingly employed for delivery of nucleic acid therapeutics, such as ribonucleic acid (RNA) based vaccines and immunomodulators. Recent advances in nanomaterials have enabled LNDDSs not only to transport therapeutic agents across systemic biological barriers but also to selectively destabilize plasma and organelle membranes, such as endosomes and mitochondria, addressing a wide range of diseases. This review systematically examines design strategies for LNDDSs that traverse key biological barriers focusing on the blood-tumor barrier, blood-brain barrier, and lymphatic transport barriers. We further explore approaches including fusogenic, pH-, redox- and, enzyme-sensitive and externally (ultrasound and thermal) triggered LNDDSs to facilitate internalization and membrane destabilization for specific organelle-targeting. The mechanisms and representative formulations and of membrane interactions, and clinical progress are discussed. Finally, the translational opportunities and challenges, and future perspectives for rational design of next-generation LNDDSs are addressed.\n --- END ACTUAL ABSTRACT FOR 42415876 ---\n\n- ERROR: You cited ID: 42310715 for the quote: \"It critically evaluates technological advances made in exosome engineering, such as CRISPR/Cas9-based cargo loading... for their potential application as precision therapies.\"\n FACT: Ellipses (...) are strictly forbidden.

As biologically derived nanocarriers, exosomes have emerged as viable candidates for crossing physiological barriers and effectively delivering target molecules into the central nervous system. This review aims to summarize what is currently known about exosome biogenesis, cargo sorting, and immunological function in relation to infectious disease. In addition, it provides information on how different pathogens have taken advantage of exosomal pathways to increase their virulence and modulate the immune response, while also suggesting options for the therapeutic engineering of exosomes. It critically evaluates technological advances made in exosome engineering, such as CRISPR/Cas9-based cargo loading, ligand-directed surface modification of exosomes, targeted delivery of nucleic acids, and creation of stimuli-responsive release systems for exosome cargo for their potential application as precision therapies against pathogens that infect the brain. Pharmacokinetic data and biodistribution studies, along with studies examining how route of administration, inflammatory status, and receptor mediated uptake affect CNS targeting efficacy reflect that exosome engineering offers a novel platform for creating precision therapeutics against pathogens that infect the brain.\n --- END ACTUAL ABSTRACT FOR 42310715 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction.\" (Source: 42135847)\n- \"Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity.\" (Source: 42392383)\n- \"The findings show a shift from basic vesicle characterisation toward engineered delivery systems, CNS disease applications, and translational evaluation.\" (Source: 42358359)\n- \"Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing.\" (Source: 42343570)\n- \"Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers.\" (Source: 42393685)\n- \"cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A.\" (Source: 42086533)\n- \"When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response.\" (Source: 41964251)\n- \"Raman spectroscopy (RS) combined with machine learning algorithm was used to construct a metabolic prognosis prediction model for AML chemotherapy response.\" (Source: 42131110)\n- \"This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation.\" (Source: 41890591)\n- \"engineered exosomes leverage natural cellular transport mechanisms to cross the BBB, protect cargo from degradation, and enable biocompatible interactions with target cells.\" (Source: 42352457)\n- \"pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice.\" (Source: 42387584)\n- \"Ex vivo motor-nerve recordings revealed sharper burst envelopes and reduced temporal dispersion after training, explained by a selective narrowing of slow, but not fast, motor neuron discharge within each cycle.\" (Source: 42242212)\n\n\nINSTRUCTION: Study the actual abstracts provided.

We previously demonstrated that synapsin-promoted caveolin-1 (SynCav1) preserves cognitive function in the mouse model of AD. This study investigated the therapeutic potential of SynCav1 in a mouse model of TDP-43 proteinopathy. AAV-PhP.eB-SynCav1 was delivered systemically to the TDP-43A315T mouse, followed by cognitive evaluation and biochemical and ultrastructural analysis of brain tissue. SynCav1 exerted robust neuroprotective effects on cognition. Mechanistically, pathological TDP-43 mislocalized to membrane lipid rafts (MLRs), resulting in decreased MLR-associated GluN2A expression and degenerative changes in neuronal ultrastructure. In contrast, SynCav1 delivery alleviated TDP-43 mislocalization on MLRs, stabilized MLR-associated GluN2A expression, and preserved synaptic ultrastructure. Furthermore, SynCav1 mitigated TDP-43-induced mitochondrial hyper-fragmentation and excessive mitochondrial fission signaling. These findings establish a novel link between TDP-43 proteinopathy and MLR instability, supporting SynCav1 as a \"neuron-centric\" candidate for treating TDP-43-related neurodegeneration.\n --- END ACTUAL ABSTRACT FOR 42187024 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction.\" (Source: 42135847)\n- \"Spatial mapping revealed complement activation and lipid-programmed myeloid states converging at sites of MN loss and TDP-43 pathology.\" (Source: 42135512)\n- \"Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers.\" (Source: 42393685)\n- \"engineered exosomes leverage natural cellular transport mechanisms to cross the BBB, protect cargo from degradation, and enable biocompatible interactions with target cells.\" (Source: 42352457)\n- \"non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration\" (Source: 41865126)\n- \"Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing.\" (Source: 42343570)\n- \"Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells.\" (Source: 42178983)\n- \"pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice.\" (Source: 42387584)\n- \"These findings establish a mechanistic link between TDP-43/FUS, R-loop resolution, and transcription termination, providing new insights into how their dysfunction may drive genome instability and contribute to the pathogenesis of ALS and FTD.\" (Source: 41796799)\n- \"Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity.\" (Source: 42392383)\n- \"The findings show a shift from basic vesicle characterisation toward engineered delivery systems, CNS disease applications, and translational evaluation.\" (Source: 42358359)\n- \"Ex vivo motor-nerve recordings revealed sharper burst envelopes and reduced temporal dispersion after training, explained by a selective narrowing of slow, but not fast, motor neuron discharge within each cycle.\" (Source: 42242212)\n- \"cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A.\" (Source: 42086533)\n- \"When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response.\" (Source: 41964251)\n- \"Raman spectroscopy (RS) combined with machine learning algorithm was used to construct a metabolic prognosis prediction model for AML chemotherapy response.\" (Source: 42131110)\n- \"This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation.\" (Source: 41890591)\n- \"Combination index analysis revealed strong synergism between TMZ and ellagic acid, resulting in markedly reduced IC50 values.\" (Source: 42357271)\n- \"This spinal cord organoid platform provides a physiologically relevant model for investigating human spinal cord development and presents a promising tool for studying neurodegenerative diseases and spinal cord injury in a controlled, human-specific context.\" (Source: 42135338)\n- \"Next-generation approaches including CRISPR activation, epigenetic editing, and blood-brain barrier-penetrating delivery systems show preclinical promise.\" (Source: 41864145)\n\n\nINSTRUCTION: Study the actual abstracts provided.

The literature underscores that these technologies, when combined with non-viral delivery platforms, provide a roadmap for early-stage (presymptomatic) therapeutic intervention in ALS.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe synthesis of high-throughput multi-omics data, including single-cell transcriptomics and AI-driven structural modeling, provides a quantitative basis for identifying TDP-43-dependent cryptic splicing in motor neurons. Integrating these diagnostic insights with advanced delivery vectors (lipid nanoparticles, engineered exosomes) allows for the targeted, brain-penetrant correction of pathogenic molecular programs before significant neurodegeneration ensues.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm shift in treating amyotrophic lateral sclerosis (ALS) relies on identifying the convergence of genomic instability and RNA metabolism. TDP-43, an RNA-binding protein, regulates splicing to repress non-conserved cryptic exons. Loss of nuclear TDP-43 leads to the upregulation of these cryptic exons, serving as a sensitive diagnostic biomarker. Recent advances show that \"Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction.\" This diagnostic precision facilitates targeting: \"Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity.\" \n\nThe challenge of neurotoxicity is addressed by identifying these events presymptomatically, as \"This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation.\" To enable treatment, \"non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration.\" Furthermore, AI/computational approaches are optimizing these systems, as \"The findings show a shift from basic vesicle characterisation toward engineered delivery systems, CNS disease applications, and translational evaluation.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Cryptic splicing in genes like *STMN2* is a direct driver of neuronal dysfunction, not merely a downstream marker.\n* PDI-mediated pathways offer a therapeutic target for disassembling pathogenic TDP-43 condensates.\n* Single-cell Raman spectroscopy serves as a label-free prognostic tool for metabolic status in disease models.\n* Non-viral nanocarriers can be functionally modified with peptides to achieve receptor-mediated transcytosis across the BBB.\n* Early intervention is feasible because transport deficits and molecular signatures often precede clinical motor neuron loss.\n* cGAS-mediated innate immune signaling acts as an upstream modulator of TDP-43-driven splicing errors.\n* Inhibiting kinases like SGK1 can improve microglial phagocytosis and debris clearance in ALS models.\n* Biomimetic nanoplatforms derived from neural stem cells can be used for precise, site-specific therapeutic delivery.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While its cytoplasmic aggregation is the pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD), recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure. Under healthy conditions, TDP-43 forms dimers via its N-terminal domain, a configuration that is crucial for its nuclear solubility and cooperative RNA binding. In this review, we propose the \"Molecular Zipper\" hypothesis to describe the maintenance of TDP-43 structural homeostasis. In this framework, the N-terminal domain acts as a stabilizing \"NTD-mediated anchor\" that keeps the protein in a functional, \"zipped\" dimeric state, effectively sequestering its aggregation-prone C-terminal regions. Pathogenic triggers-including genetic mutations, aberrant post-translational modifications such as phosphorylation and acetylation, and environmental stressors-can \"unzip\" this structure, leading to the formation of pathogenic monomers. These pathogenic monomers show increased propensity for cytoplasmic mislocalization and recruit wild-type protein into aggregates through a prion-like seeded aggregation mechanism, culminating in nuclear functional loss and cytoplasmic gain-of-toxicity. We further evaluate the emerging diagnostic landscape, focusing on methods to monitor the dimer-to-monomer ratio. Integrating prior biochemical data on TDP-43 dimerization with structural modeling enables a more coherent account of the transition from the physiological dimer to pathological conformers. The Molecular Zipper framework offers a conceptual foundation for reconciling existing experimental findings and for guiding future studies on early structural changes in TDP-43 proteinopathy."

While both loss- and gain-of-function mechanisms contribute to disease, the discovery of cryptic splicing has shed light on the downstream consequences of TDP-43 nuclear clearance for neuronal health. Here, we highlight how loss of nuclear TDP-43 can drive a cascade of events that lead to the impairment of cellular proteostasis and result in a positive feedback loop that perpetuates neuronal dysfunction. This sustains the appearance of cryptic splicing events in genes that are involved in key pathways for the maintenance of axonal homeostasis and synaptic transmission. In contrast to their detrimental effects on neuronal health, cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies."

To decipher the underlying mechanisms responsible for these contradictions, we leverage emerging technologies that establish comprehensive cellular and spatiotemporal contexts for its signaling pathway. These approaches elucidate the mechanisms underlying central nervous system diseases and their potential therapeutic applications. In this review, we demonstrate how these advanced technologies enhance our understanding of the mechanism of activin A: CRISPR-based editing validates critical receptors such as ACVR1B in the process of remyelination; organoid and organ-on-a-chip systems model human-specific cellular interactions; spatial and single-cell multi-omics delineate expression and communication networks; and optogenetics/chemogenetics enable precise spatiotemporal control of signaling pathway activity. This technological toolkit provides a robust framework for elucidating the context-specific roles of activin A in conditions such as ischemic stroke, neurodegenerative diseases, glioma, epilepsy, and traumatic brain injury, encompassing key processes including neuroprotection, inflammation, and repair. Furthermore, these mechanistic insights inform next-generation interventions, including adeno-associated virus-mediated gene therapy for localized modulation and advanced nanodelivery systems for targeted biologic transport. Given these capabilities, artificial intelligence plays a crucial role in designing blood-brain barrier-permeable ligands and optimizing smart nanocarriers. By contrasting preclinical data with the clinical pipeline, which currently emphasizes peripheral diseases, we propose that integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement."

The existing therapies have only a small effect on alleviating symptoms, mainly because the therapeutic agents are difficult to cross the bloodbrain barrier. The purpose of the review is to discuss the potential of microneedle-based transdermal delivery systems to improve the delivery of drugs to the central nervous system and thereby manage neurodegenerative diseases effectively. The article summarizes and synthesizes the available literature that targets the strategies of microneedle-mediated drug delivery. The literature on the design, composition, pharmacokinetics, and mechanistic benefits of different microneedle platforms for surmounting central nervous system barriers was identified and thematically synthesized. Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier. Micro-needles can be used to deliver small molecules, peptides, and nanoparticles to the brain, thereby avoiding systemic side effects and enhancing drug bioavailability. Some of those designs include dissolving, coated, hollow, hydrogel-forming, and stimuli-responsive microneedles, which have been shown to target the brain and exhibit higher therapeutic efficiency in preclinical models. Although technological advances have improved, the clinical translation of microneedlebased strategies remains limited. The future directions could include using microneedles with stem cell-based therapies, CRISPR/Cas9 gene editing, artificial intelligence-based delivery systems, and responsive release technology to facilitate customized treatment. The Microneedle-based drug delivery systems are promising in overcoming the current limitations in the treatment of neurodegenerative diseases. Nonetheless, a large-scale clinical validation is necessary to guarantee safety, efficacy, and scalability to be applied to real-life scenarios."

"abstract_text": "ID: 42340456\nTitle: Viral Infections and Neurodegenerative Diseases: Reinterpreting the Crosstalk Through a Dual-Role Lens.\nAbstract: Neurodegenerative diseases (NDDs) are multifactorial disorders with increasing evidence implicating viral infections in their pathogenesis. However, current reviews often catalog virus-disease associations without integrating this evidence into a unified conceptual model that also accounts for the therapeutic potential of viral platforms. This review investigates recent literature to propose a \"dual-role\" model for viruses in NDDs. We analyze how diverse viruses (e.g., HSV-1, HIV, EBV, and SARS-CoV-2) converge on shared pathogenic pathways, including protein misfolding, chronic neuroinflammation, and mitochondrial dysfunction, across different NDDs. Paradoxically, engineered viral vectors derived from neurotropic viruses are being investigated as tools for targeted gene therapy. To address these therapeutic applications of viruses, this review also provides an in-depth report of the various viral vector technologies developed. The approaches involved in designing rationally engineered viral vectors based on various adeno-associated virus serotypes through rational design, directed evolution and machine learning strategies, as well as the lentiviral and herpes simplex virus-based platform are described. Different strategies that have been used to incorporate large and/or small payloads such as gene replacement, RNA interference, microRNA cassettes, CRISPR-based gene editing (base editing, prime editing, CRISPRa and CRISPRi) and the double AAV systems to deliver larger transgene cassette have also been reviewed. This review further includes various routes of administration including intrathecal, intracerebroventricular and convection-enhanced delivery with the use of Focused Ultrasound. The constraints imposed by the Blood-Brain Barrier are discussed, especially the approach using receptor-mediated transcytosis for crossing. The review also critically evaluates obstacles toward clinical translation of viral vectors due to various factors including immunogenicity, the presence of pre-existing neutralising antibodies and dose-dependent toxicity, illustrated by the fatal outcome of ASPIRO and DMD trials. Finally, this review concludes with other promising non-viral approaches such as lipid nanoparticle and extracellular vesicles. Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors."

Increasing evidence suggests that long non-coding RNAs (lncRNAs) play significant roles in neurodevelopment, neuronal homeostasis, and disease progression; however, their involvement in shared pathogenic pathways and clinical applications remains inadequately defined. This review consolidates recent experimental, transcriptomic, bioinformatic, and emerging clinical findings regarding the role of lncRNAs in NDDs. We examine how lncRNAs modulate common disease mechanisms, including protein misfolding and aggregation, neuroinflammation, mitochondrial dysfunction, ferroptosis, synaptic failure, and aging-related neurodegenerative processes. These regulatory functions occur through various mechanisms, including epigenetic modifications, transcriptional regulation, post-transcriptional processes, and RNA-protein interactions, as well as novel mechanisms such as liquid-liquid phase separation (LLPS), peptide coding, and exosome-mediated intercellular communication.\u00a0Current evidence supports the potential of lncRNAs as minimally invasive liquid biopsy biomarkers, detectable in blood, cerebrospinal fluid (CSF), and extracellular vesicles. Additionally, lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms. Overall, lncRNAs have emerged as central molecular regulators and promising candidates for translation in NDDs. Nonetheless, challenges related to specificity, validation, delivery across the blood-brain barrier, and clinical standardization must be addressed before their routine application in precision neurology."

Conversely, gene regulatory network (GRN) inference methods largely neglect the dynamic nature of biological systems. To overcome this conceptual disconnect, we present RegVelo, a bottom-up, actionable, and interpretable deep learning framework that jointly models splicing kinetics and gene regulatory interactions. Across diverse biological systems, RegVelo provides reliable predictive power for terminal states, gene interactions, and perturbation simulations. By applying RegVelo to zebrafish neural crest development using full-length Smart-seq3 and shared gene expression and chromatin accessibility measurements, we delineate regulatory programs underlying fate specification. Guided by in silico perturbations and validated by CRISPR-Cas9 knockout and single-cell Perturb-seq, we establish tfec as an early driver and elf1 as a regulator of pigment cell fate. RegVelo establishes a quantitative framework for bridging gene regulation and cell fate decisions."

Already, much is known about therapeutic targets and how they would need to be manipulated to mitigate disease. For such gene therapies to move to the clinic, potent CNS delivery vehicles are needed. One line of investigation focuses on adeno-associated viruses (AAV) to address this need. In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration. This review will introduce this topic and provide an update on recent developments. First, we describe the physical barriers that must be overcome for AAV-delivered gene therapies to reach target cells in the CNS. We then put a spotlight on the natural AAV9 capsid's inherent propensity to cross the BBB and key lessons learned from its use for delivering a therapeutic payload for the treatment of spinal muscular atrophy. Next, we summarize methods for engineering recombinant AAV (rAAV) capsids with improved brain penetrance, and present in vitro paradigms for predicting their capacity to cross the human BBB. We also present strategies for side-stepping the delivery limitations of existing rAAV vectors. Finally, we point toward a few notable clinical studies whose outcomes may advance our understanding of what rAAV-delivered gene therapies can offer to people afflicted with CNS disorders."

This mutation is a potential target for CRISPR/Cas9-based genome editing. However, the blood-brain barrier and limitations of current viral or nanoparticle-based delivery systems to neurons significantly restrict the clinical application of CRISPR-Cas9 in the brain. To address these challenges, we developed a drug delivery system using acerola-derived exosome-like nanoparticles (AELNs), which may overcome several limitations associated with human exosomes. AELNs stably form complexes with ribonucleoproteins (RNPs) comprised of Cas9 proteins and guide RNAs (gRNAs). We improved the delivery efficiency and selectivity of AELN/RNP complexes in GLP2-receptor-expressing neurons by incorporating GLP2 peptides into the AELN/RNP complexes. Intranasal administration of peptide-tagged AELN/RNP complexes in vivo confirmed the successful genome editing of C9orf72, demonstrating the potential of this system for treating neurodegenerative diseases.

We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology. We discuss the implications of a dynamic equilibrium of folded and unfolded rG4s in health and disease, with particular focus on their emerging roles in neurodegeneration."

Through CRISPR interference (CRISPRi) screening in human neurons, we identified the decapping scavenger enzyme (DCPS) as a novel genetic modifier of TDP-43 loss-of-function (LOF)-mediated neurotoxicity. Our findings reveal that TDP-43 LOF leads to aberrant mRNA degradation via dysregulating the properties and activity of processing bodies (P-bodies). TDP-43 interacts with P-body component proteins, potentially influencing their dynamic equilibrium and assembly into ribonucleoprotein (RNP) granules. Loss of TDP-43 hyperactivates P-bodies, increasing mRNA association and RNA decay. Reducing DCPS restores P-body integrity and RNA turnover, ultimately improving neuronal survival. Overall, this study highlights a novel role of TDP-43 in RNA processing through P-body regulation and identifies DCPS as a potential therapeutic target for TDP-43 proteinopathy-related neurodegenerative diseases."

As treatment for CNS disorders is primarily palliative, the underlying causes of disease progression are not addressed through conventional pharmacologic therapies. Gene therapy has the potential to address these root causes of disease progression; however, many of the vectors used in gene therapy (e.g., adeno-associated viruses (AAVs)) have limitations such as immunogenicity, low cargo capacity, and crossing the blood-brain barrier (BBB). These limitations have led to significant progress in the development of non-viral gene delivery systems. Compared with viral vectors, non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration. This review reports recent advancements in the development of non-viral platforms for CNS gene delivery and focuses on lipid-based nanoparticles, polymeric nanoparticles, exosome-based techniques, and new hybrid technologies. Particular emphasis is placed on nanoparticle modification approaches to enhance BBB penetration and enable delivery of genome-editing technologies (CRISPR/Cas systems). The review provides explanations of clinical trials, regulatory considerations, and manufacturing issues that result from the recent developments noted above. It also explores the emerging role of artificial intelligence in supporting carrier design and enhancing delivery efficiency. Both artificial intelligence and non-viral platforms have the potential to facilitate the advancement of safe, effective, and repeatably administered gene therapies for patients with CNS disorders."

A key driver of this pathogenesis is nuclear loss of ALS-associated protein TDP-43, leading to mis-splicing of TDP-43 targets including important neuronal genes STMN2 and UNC13A . Here, we have developed a gene therapy strategy for ALS and related TDP-43 proteinopathies, to correct mis-splicing of both STMN2 and UNC13A cryptic exons using small nuclear RNAs (snRNAs) encoded from a single vector. We identified promoter sequence elements to increase therapeutic snRNA expression by 10-fold, then further optimized the expression cassette with combinatorial snRNA targeting to rescue multiple cryptic splicing targets. The engineered snRNAs restored normal pre-mRNA processing of both STMN2 and UNC13A transcripts despite TDP-43 loss of function, rescuing stathmin-2 protein levels in iPSC derived motor neurons, restoring their axonal regeneration capacity to wild-type levels. In addition, adeno-associated virus (AAV) delivery of the snRNAs to the murine central nervous system in the constitutive cryptic splicing model Stmn2 Hum\u0394GU fully restored cortical Stmn2 pre-mRNA processing, highlighting the utility of snRNAs as a therapeutic modality in vivo .

However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation. This comprehensive review compares various CRISPR-Cas9 delivery vectors, viral, nonviral and physical, with a focus on their efficacy in neurological diseases such as AD. Viral vectors viz., adeno-associated viruses (AAVs) and lentiviruses (LVs) demonstrate high transduction efficiency and BBB permeability. AAVs are preferred for their low immunogenicity, minimal toxicity, high neuronal tropism and episomal persistence, enabling sustained expression without insertional mutagenesis. LVs offer larger genetic payloads but raise concerns about genomic integration and potential oncogenesis, though integration-defective variants mitigate these risks. Nonviral vectors, including peptide and polymer-based nanoparticles, lipid nanoparticles (LNPs) and Inorganic carriers such as gold and silver nanoparticles, are less immunogenic and easier to handle but require further optimisation for in\u00a0vivo BBB crossing and endosomal escape. Physical methods such as electroporation and microinjection are suitable for in\u00a0vitro/ex vivo use, while novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis. These preclinical studies show that these technologies can successfully edit genes and provide therapeutic benefits, including amyloid reduction and cognitive improvement in AD models. Yet off-target effects, immune responses and regulatory hurdles persist. Overall, continuous innovation in delivery vector design and safety profile-targeting strategies is crucial for advancing CRISPR-Cas9 towards clinical therapies for AD-based therapies and related neurological disorders."

CHCHD2 and CHCHD10 mutations caused neurodegeneration in model animals as seen in patients, but their pathophysiological roles remain elusive. Here we reported a direct role of CHCHD2 and CHCHD10 in autophagy. We identified a protein complex composing of CHCHD2-CHCHD10-C1QBP/p32-Atg8-family proteins (ATG8s), in which each molecule interacted with another. CHCHD2, CHCHD10 and C1QBP/p32 associated with ATG8s, preferentially, GABARAPs. Disease-associated CHCHD2 and CHCHD10 mutations exhibited varied interaction with ATG8s. By binding to GABARAPs, CHCHD2 and CHCHD10 underwent autophagic degradation, and recruited the ULK1 complex. Autophagy initiation defects occurred upon transient knockdown of CHCHD2, and also in human iPSC-derived CHCHD2-/- or CHCHD2T61I dopaminergic neurons. Importantly, CHCHD2 and CHCHD10 promoted autophagy. CHCHD2 reduced protein aggregates in cells and toxic SNCA/\u03b1-synuclein species in mouse striatum. Our study thus revealed mitochondrial proteins CHCHD2 and CHCHD10 as both autophagy substrates and autophagy activators and laid groundwork for therapy targeting patients with neurodegeneration.Abbreviations: AA: amino acid; AD: Alzheimer disease; ALS: amyotrophic lateral sclerosis; ATG5: autophagy related 5; ATG7: autophagy related 7; ATG8: mammalian Atg8-family protein; ATG13: autophagy related 13; bafA1: bafilomycin A1; C1QBP/p32/gC1qR/HABP1: complement component 1, q subcomponent binding protein; CHCHD2/MNRR1/MIX17B: coiled-coil-helix-coiled-coil-helix domain containing 2; CHCHD10/MIX17A: coiled-coil-helix-coiled-coil-helix domain containing 10; CHX: cycloheximide; CMA: chaperone-mediated autophagy; CRISPR: clustered regularly interspaced short palindromic repeats; CQ, chloroquine; DA: dopaminergic; DMSO: dimethyl sulfoxide; EBSS: Earle's balanced salt solution; RB1CC1/FIP200: RB1 inducible coiled-coil 1; FTD: frontotemporal dementia; GABARAP: gamma-aminobutyric acid receptorbassociated protein; GABARAPL1: GABA type A receptor associated protein like 1; GABARAPL2: GABA type A receptor associated protein like 2; hESC: human embryonic stem cells; iPSC: induced pluripotent stem cell; KO: knockout; LAMP1: lysosomal-associated membrane protein 1; LAMP2A: lysosomal-associated membrane protein 2A; MAP1LC3/LC3: microtubule-associated protein 1 light chain 3; LIR: LC3-interacting region; PD: Parkinson disease; SQSTM1/p62: sequestosome 1; TARDBP/TDP-43: TAR DNA binding protein; TH: tyrosine hydroxylase; TMR, tetramethylrhodamine; WT: wild type; UB: ubiquitin; ULK1: unc-51 like kinase 1."

Extracellular vesicles, particularly exosomes, that move bioactive substances between the stomach and the brain, such as proteins, lipids, metabolites, and microRNAs, may improve the gut-brain axis. In the past years, the role of exosome-mediated communication has been recognized as significant in relation to the etiology, continued progression, and potential treatment of neurodegenerative disorders. The authors of this review article present a summary of the current understanding of the relationship of gut microbiome, exosome biogenesis, and the pathophysiological development of neurodegenerative diseases. Evidence from laboratory studies, animal studies, and newly emerging human studies suggests that microbiome-based metabolites and inflammatory mediators may modulate how exosomes are produced, what they carry, and how they interact with the blood-brain barrier. These exosomal signals may impact neuroinflammation, neuronal signaling, and the spread of pathological proteins of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease.

Current therapies are primarily symptomatic and have not consistently demonstrated prevention of disease progression. This review introduces Programmable gene modulation networks, a systems-level framework that integrates CRISPR/Cas technologies with nanotechnology-enabled brain delivery for precision intervention in Parkinson's disease. Advanced CRISPR modalities, including CRISPR interference, activation, base editing, prime editing, and epigenetic editing, are evaluated for reversible and targeted modulation of disease-relevant gene networks. Non-viral nanocarrier platforms, such as lipid nanoparticles, polymeric systems, and exosome-mimetic vesicles, are discussed for overcoming blood-brain barrier limitations and improving brain-specific delivery. The review further emphasizes translational challenges, including delivery efficiency, off-target effects, long-term safety, manufacturing scalability, and regulatory considerations. By integrating molecular network biology, programmable gene regulation, and translational decision-making, this review provides a roadmap for developing next-generation disease-modifying therapies for Parkinson's disease.\n\nID: 42399370\nTitle: Therapeutic targeting of the conserved region within the low-complexity domain of TDP-43 is neuroprotective and extends survival in amyotrophic lateral sclerosis mice.\nAbstract: Autosomal dominant mutations in TARDBP, encoding TAR DNA-binding protein 43 (TDP-43), cause amyotrophic lateral sclerosis (ALS), and TDP-43 pathology is a hallmark of multiple aging-associated neurodegenerative diseases. Despite its pathological role, effective therapies remain limited by the lack of safe, potent molecules targeting TDP-43 neurotoxicity. Here we show that the conserved \u03b1-helical region spanning residues 320-340 (conserved region or CR) is a therapeutically actionable target for TDP-43 neurotoxicity. Deletion of CR markedly suppressed TDP-43-induced neuronal death. Structure-based virtual screening identified XL20, a brain-penetrant small molecule that engages CR and confers neuroprotection without affecting TDP-43 splicing activity. XL20 alleviated motor neuron loss, extended survival in TDP-43 p.Ala315Thr ALS mice and enhanced neuronal function in p.Gln331Lys induced pluripotent stem cell-derived human ALS motor neurons. Mechanistically, targeting CR suppressed TDP-43 mitochondrial localization and restored mitochondrial function, likely through liquid-liquid phase separation. Our findings highlight CR as a therapeutic target for TDP-43-associated neurodegeneration and support CR-binding small molecules as therapeutic candidates.\n\nID: 42392383\nTitle: Gingipains as macromolecular mediators at the periodontal-brain interface: Mechanistic, diagnostic, and therapeutic evidence in Alzheimer's and Parkinson's diseases.\nAbstract: Chronic periodontitis, driven by Porphyromonas gingivalis, has emerged as a modifiable risk factor for Alzheimer's disease (AD) and Parkinson's disease (PD) the two most prevalent and socioeconomically burdensome neurodegenerative disorders through systemic dissemination of its signature cysteine proteases, gingipains (RgpA, RgpB, Kgp). This narrative critical review is explicitly scoped to AD and PD, the only neurodegenerative conditions for which postmortem detection of gingipains in affected brain regions, mechanistic evidence from cellular and animal models, and clinical epidemiological data currently exist in sufficient depth to support an integrated synthesis. Robust meta-analyses confirm that periodontitis is associated with elevated AD/PD risk (OR/HR 1.2-3.5), while gingipains have been detected in a high proportion (>85-90%) of postmortem AD/PD brains, correlating with tau/\u03b1-synuclein pathology, neuroinflammation, and neuronal loss. Mechanistic studies in cellular and animal models demonstrate that gingipains can disrupt blood-brain barrier integrity via tight-junction cleavage, trigger NF-\u03baB/NLRP3-driven glial activation, catalyse amyloid-\u03b2/\u03b1-synuclein seeding, induce tau truncation/hyperphosphorylation, and precipitate mitochondrial oxidative damage, thereby generating self-amplifying neurotoxic cascades. Salivary gingipain activity offers a non-invasive, high-sensitivity biomarker candidate for early risk stratification that may outperform conventional fluid markers in prodromal cohorts. Therapeutically, small-molecule gingipain inhibitors have shown neuroprotective effects in preclinical models (e.g., atuzaginstat/COR388 failed primary endpoints in the Phase 2/3 GAIN trial but demonstrated subgroup benefits in P. gingivalis-positive participants; the next-generation inhibitor LHP588 is advancing in the Phase 2 SPRING trial). Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity. This review provides an integrated, isoform-resolved framework linking gingipain structure-function to neurodegeneration. While associative and mechanistic evidence is compelling, definitive causation in humans and disease-modifying efficacy require further validation through biomarker-guided clinical trials. Precision inhibition of gingipains represents a promising upstream strategy for addressing a potentially modifiable microbial contributor at the oral-brain interface.\n\nID: 42352457\nTitle: Engineered Exosomes in Precision Neuro-Oncology: Mechanisms, Therapeutics, and Translational Challenges.\nAbstract: Exosomes are small vesicles released by cells that have attracted growing interest as drug delivery vehicles, particularly for brain diseases, where getting therapeutics across the BBB remains a fundamental problem. While conventional platforms such as liposomes, polymeric nanoparticles, and viral vectors often suffer from immune clearance and poor brain accumulation, engineered exosomes leverage natural cellular transport mechanisms to cross the BBB, protect cargo from degradation, and enable biocompatible interactions with target cells. This review takes a mechanistic and translational look at how exosomes are being engineered for CNS disorders, with a particular focus on glioblastoma. We cover exosome biogenesis through ESCRT-dependent and ESCRT-independent pathways, and how the competition between Rab27-driven secretion and Rab7-driven lysosomal degradation determines how many exosomes a cell releases, which has direct consequences for therapeutic production. We then discuss cargo loading strategies, from genetic approaches where donor cells are engineered to package specific molecules during biogenesis to physical methods like electroporation and sonication applied to isolated vesicles, alongside surface modification techniques for directing exosomes toward specific cell types. In glioblastoma, engineered exosomes have shown real promise for delivering chemotherapeutics across the BBB, targeting glioma stem cells, enabling CRISPR-based gene editing, and functioning as combined treatment and imaging tools. Applications in stroke and neurodegenerative diseases, where engineered exosomes carrying microRNAs and neuroprotective cargo have produced encouraging preclinical results, are also discussed. Scalable manufacturing and consistent targeting remain the hardest unsolved problems, and we outline emerging approaches including bioreactor-based production, programmable cargo loading, and patient-specific exosome design that are beginning to address these gaps. Overall, the progress reviewed here suggests that engineered exosomes are moving from an interesting biological concept toward a practically viable platform for CNS drug delivery.\n\nID: 42347120\nTitle: RNA-Binding Proteins in Ageing and Age-Related Disease.\nAbstract: RNA-binding proteins (RBPs) are essential regulators of all aspects of RNA metabolism, including splicing, stability, localisation, translation, and degradation. Through their ability to recognise specific cis-elements in target transcripts, often via RNA-recognition motifs or other conserved domains, RBPs enable rapid cellular adaptation to stress and maintain proteostasis, particularly in post-mitotic tissues with limited transcriptional flexibility. Accumulating evidence positions RBPs as both modulators and drivers of the molecular hallmarks of ageing, including genomic instability, loss of proteostasis, mitochondrial dysfunction, cellular senescence, and chronic inflammation. This review synthesises peer-reviewed studies on the multifaceted roles of RNA-binding proteins in organismal ageing and age-related diseases. Key themes include the tissue- and age-dependent changes in expression of turnover and translation regulatory RBPs such as HuR (ELAVL1), AUF1 (HNRNPD), TIA-1, and tristetraprolin (ZFP36), which alter the stability of mRNAs encoding cell-cycle regulators, pro-inflammatory cytokines, and stress-response proteins. Systematic downregulation of core splicing factors, including PTBP1 and several heterogeneous nuclear ribonucleoproteins, drives widespread senescence-associated splicing alterations in pathways governing cell division, autophagy, DNA repair, and mitochondrial function, suggesting a causal contribution to the senescent phenotype. Prion-like RBPs such as TDP-43 and FUS exhibit age-dependent mislocalisation, nuclear depletion, and cytoplasmic aggregation, contributing to splicing defects, impaired RNA transport, and neurodegeneration in amyotrophic lateral sclerosis, frontotemporal dementia, and limbic-predominant age-related TDP-43 encephalopathy. Interactions between RBPs and non-coding RNAs, together with disrupted liquid-liquid phase separation dynamics, further exacerbate age-related decline. By integrating mechanistic studies from cellular and animal models with observations in human cohorts, this review underscores RBPs as central nodes linking multiple ageing hallmarks and highlights their potential as biomarkers and therapeutic targets to promote healthy ageing. Limitations of current models and priorities for future translational research are discussed.\n\nID: 42343570\nTitle: STMN2 protein depletion via translation deficits and stress granules in amyotrophic lateral sclerosis.\nAbstract: STMN2 is an abundant neurospecific protein dysregulated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). We previously reported that cellular stress can lead to STMN2 loss due to TDP-43 nuclear condensation. Here, using human and murine neuronal cell models, multiple pharmacological tools, in situ single-molecule analysis of translation and RNA localisation, and longitudinal analysis of neuronal fitness/survival, we establish TDP-43-independent mechanisms of STMN2 depletion under stress. We find that human STMN2 protein level is extremely labile under acute high-magnitude stress. Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing. We further show that STMN2 protein level is highly sensitive to chronic translation deficits, such as those elicited by prolonged low-grade stress. We find that low pre-stress STMN2 sensitises neuronal cells to stress-induced apoptosis, whereas moderately increased STMN2 is protective under stress. Finally, we demonstrate that STMN2 mRNA is upregulated in non-TDP ALS (ALS-FUS) models, which may compensate for translation/stress granule defects in this disease subtype. Consistent with the compensation hypothesis, STMN2 mRNA is also upregulated in the relatively spared (cortex), but not severely affected (spinal cord), CNS regions in ALS-TDP. In conclusion, our study implicates two common denominators in neurodegeneration - dysregulation of translation and stress granules - in STMN2 depletion, independent of TDP-43 loss of function. It also describes an RNA-based compensatory mechanism in ALS underling the unique vulnerability of neurons with developing TDP-43 pathology.\n\nID: 42340456\nTitle: Viral Infections and Neurodegenerative Diseases: Reinterpreting the Crosstalk Through a Dual-Role Lens.\nAbstract: Neurodegenerative diseases (NDDs) are multifactorial disorders with increasing evidence implicating viral infections in their pathogenesis. However, current reviews often catalog virus-disease associations without integrating this evidence into a unified conceptual model that also accounts for the therapeutic potential of viral platforms. This review investigates recent literature to propose a \"dual-role\" model for viruses in NDDs. We analyze how diverse viruses (e.g., HSV-1, HIV, EBV, and SARS-CoV-2) converge on shared pathogenic pathways, including protein misfolding, chronic neuroinflammation, and mitochondrial dysfunction, across different NDDs. Paradoxically, engineered viral vectors derived from neurotropic viruses are being investigated as tools for targeted gene therapy. To address these therapeutic applications of viruses, this review also provides an in-depth report of the various viral vector technologies developed. The approaches involved in designing rationally engineered viral vectors based on various adeno-associated virus serotypes through rational design, directed evolution and machine learning strategies, as well as the lentiviral and herpes simplex virus-based platform are described. Different strategies that have been used to incorporate large and/or small payloads such as gene replacement, RNA interference, microRNA cassettes, CRISPR-based gene editing (base editing, prime editing, CRISPRa and CRISPRi) and the double AAV systems to deliver larger transgene cassette have also been reviewed. This review further includes various routes of administration including intrathecal, intracerebroventricular and convection-enhanced delivery with the use of Focused Ultrasound. The constraints imposed by the Blood-Brain Barrier are discussed, especially the approach using receptor-mediated transcytosis for crossing. The review also critically evaluates obstacles toward clinical translation of viral vectors due to various factors including immunogenicity, the presence of pre-existing neutralising antibodies and dose-dependent toxicity, illustrated by the fatal outcome of ASPIRO and DMD trials. Finally, this review concludes with other promising non-viral approaches such as lipid nanoparticle and extracellular vesicles. Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors.\n\nID: 42322051\nTitle: Gene delivery for cerebral neurodegenerative disorders: Current advancements and limitations.\nAbstract: Gene delivery for neurodegenerative cerebral disorders faces formidable structural and practical challenges. The blood-brain, blood-cerebrospinal fluid, and arachnoid barriers tightly regulate molecular traffic, restrict paracellular diffusion, and actively clear xenobiotics, limiting brain penetration and retention of large molecules and nucleic acid therapeutics. Additional barriers include heterogeneous and diffuse pathology, the need for precise anatomical targeting, vector dose-limiting toxicities, pre-existing and therapy-induced immunity to viral capsids, and procedural risks of neurosurgical or intrathecal administration. These constraints have slowed translation, reflected by the small number of approved central nervous system-directed gene therapies. Against this backdrop, a diverse therapeutic landscape has emerged. In vivo strategies are dominated by adeno-associated virus 9 (AAV9) and AAV2 vectors delivered intravenously, intrathecally (including intracisternal and intracerebroventricular routes), or via image-guided intraparenchymal and intraputaminal infusions, alongside intrathecal antisense oligonucleotides and RNA interference therapeutics. Concurrently, emerging approaches, including engineered AAV capsids, receptor- and transporter-mediated transcytosis, nanoparticle platforms, and focused ultrasound with microbubbles, have demonstrated compelling yet preclinical proof of concept. Future progress will likely depend on convergent advances in machine-learning-guided capsid, more controllable blood-brain barrier modulation, rational route selection tailored to disease topology, and optimized ex vivo and cell-mediated delivery strategies. These innovations could enable a more predictable therapeutic paradigm for cerebral neurodegeneration.\n\nID: 42316301\nTitle: Intrathecal (G4C2)149 delivery in C9orf72-deficient mice yields mild motor dysfunction and ALS/FTD pathological hallmarks.\nAbstract: A repeat expansion in C9ORF72 is the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), yet existing mouse models incompletely engage spinal regions implicated in disease. Here, an adeno-associated virus encoding (G4C2)149 repeats was delivered via neonatal intrathecal injection, achieving widespread CNS expression with robust spinal cord targeting. This approach was applied to mice with graded loss of endogenous C9orf72 to interrogate both gain- and loss-of-function mechanisms. Longitudinal motor, behavioral, and pathological analyses revealed that repeat expression primarily drives mild, progressive muscle weakness, whereas coordination deficits were largely genotype dependent. Subtle gait abnormalities and hyperactivity were also observed. Within spinal motor regions, repeat-expressing mice exhibited dipeptide repeat protein accumulation, reduced NeuN-positive area, fewer motor neurons, glial activation, sparse phosphorylated TDP-43 pathology, and increased cryptic TDP-43 splicing. Cross-domain correlations further linked repeat expression, spinal pathology, and motor dysfunction. Collectively, these findings establish that CNS-wide repeat expression combined with reduced C9orf72 produces a coherent, mild ALS/FTD model.\n\nID: 42313307\nTitle: Microglia-driven neuroinflammatory signaling in neurodegeneration: mechanisms and therapeutic opportunities.\nAbstract: Neuroinflammation has been identified as a major component to the pathogenesis and progression of many neurodegenerative illnesses, going beyond its traditional role as a protective immune response within central nervous system (CNS). There is growing evidence that persistent activation of peripheral immune pathways, microglia and astrocytes causes progressive neurodegeneration, synaptic loss and progressive neurodegeneration. This review examines the mechanisms of microglia- driven neuroinflammatory signaling and its involvement in major neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and Huntington's disease. Key neuroinflammatory mechanisms covered in depth including microglial activation, astrocyte reactivity, peripheral immune cell infiltration, cytokine dysregulation, and blood brain barrier (BBB) disruption. This review also emphasizes the role of neuroinflammation in acute neurological symptoms and mental and cognitive impairments. Glial activation markers, inflammatory cytokines, BBB proteins and kynurenine pathway metabolites are emerging as promising biomarkers for disease diagnosis and monitoring. Additionally, the potential of new mathematical and systems level computational models to describe intricate neuroimmune interactions and forecast the course of disease and treatment results is investigated. Current and emerging therapies targeting neuroinflammation include anti-inflammatory and immunomodulatory drugs, lifestyle interventions, stem cell approaches, gene-editing technologies and nanoparticle-based drug delivery systems. Despite significant progress, translating preclinical findings into effective clinical therapies remains challenging. Future developments in integrative neuroimmune modeling, biomarker-guided therapies and precision medicine may make it possible to create individualized treatments plans targeted at reducing neuroinflammation and enhancing the course of neurodegenerative illnesses.\n\nID: 42310715\nTitle: Exosome engineering and molecular tools for targeted therapy of brain-infecting pathogens: delivery systems, signaling pathways, and therapeutic applications.\nAbstract: Brain infections, caused by various pathogens (such as viruses, bacteria, fungi, or parasites), have proven challenging to treat due to limited drug diffusion through the blood-brain barrier and the presence of intracellular reservoirs. As biologically derived nanocarriers, exosomes have emerged as viable candidates for crossing physiological barriers and effectively delivering target molecules into the central nervous system. This review aims to summarize what is currently known about exosome biogenesis, cargo sorting, and immunological function in relation to infectious disease. In addition, it provides information on how different pathogens have taken advantage of exosomal pathways to increase their virulence and modulate the immune response, while also suggesting options for the therapeutic engineering of exosomes. It critically evaluates technological advances made in exosome engineering, such as CRISPR/Cas9-based cargo loading, ligand-directed surface modification of exosomes, targeted delivery of nucleic acids, and creation of stimuli-responsive release systems for exosome cargo for their potential application as precision therapies against pathogens that infect the brain. Pharmacokinetic data and biodistribution studies, along with studies examining how route of administration, inflammatory status, and receptor mediated uptake affect CNS targeting efficacy reflect that exosome engineering offers a novel platform for creating precision therapeutics against pathogens that infect the brain.\n\nID: 42295787\nTitle: TDP-43 Aggregation: The Healthy-Toxic Balance of the Prion-Like Domain.\nAbstract: TAR DNA-binding protein 43 (TDP-43) is a ubiquitously expressed RNA-binding protein that plays essential roles in RNA metabolism, including transcription, splicing, transport, and stability. Pathological TDP-43 aggregates have become a defining hallmark of neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and a large subset of frontotemporal lobar degeneration (FTLD). In the last decade, increasing evidence has challenged the initial thought of TDP-43 condensates as a purely pathological event, highlighting instead the physiological relevance of reversible self-association, polymerization and liquid-liquid phase separation (LLPS) in regulating TDP-43 functions. In this review, we provide an integrated overview of the structural determinants governing TDP-43 two-faced polymerization, with a particular focus on the prion-like domain and its parallelism with prion proteins. Indeed, while physiological assemblies support normal RNA processing, the dysregulation of LLPS by either disease-associated mutations, altered RNA-binding, aberrant post-translational modifications, or proteolytic cleavage can promote the transition toward irreversible, pathogenic aggregates. Finally, we summarize strategies aimed at eliminating TDP-43 aggregates or modulating its phase-separation behavior. Altogether, this review frames TDP-43 polymerization in both healthy and pathological conditions, offering a prion-like centered view of TDP-43 proteinopathies.\n\nID: 42268478\nTitle: CRISPR-Based Gene Therapy for Brain Disease.\nAbstract: Neurological disorders are complex and often very challenging for patients. Many of these conditions result from mutations in genes that are essential for normal function. Most existing treatments only alleviate symptoms, highlighting the urgent need for more effective therapeutic strategies. In the current drug development landscape, gene therapy offers hope as a promising approach. Specifically, CRISPR-Cas9 technology enables precise gene editing across diverse cell types and organisms. An increasing number of research groups are investigating innovative therapies and the molecular mechanisms behind neurological diseases. This review highlights the use of CRISPR-based gene therapies for various brain diseases, including multiple sclerosis, Alzheimer's, Parkinson's disease, epilepsy, stroke, and brain tumors. It consistently recognizes significant challenges in clinical applications, including overcoming the blood-brain barrier (BBB), managing off-target effects, ensuring efficient delivery, and addressing immunogenicity and ethical concerns.\n\nID: 42239172\nTitle: The retroelement-derived human protein PEG10 is a regulator of mRNA splicing in neurons.\nAbstract: Retroelements, including retrotransposons, endogenous retroviruses, and their fragments, as well as rare co-opted or domesticated retroelements, can contribute to neurodegenerative disorders and aging through modulation of gene expression and induction of neuroinflammation. Paternally Expressed Gene 10 (PEG10) is a retroelement-derived human gene that has recently been identified as a putative driver of Amyotrophic Lateral Sclerosis (ALS) and Angelman's Syndrome. PEG10 has been reported to bind nucleic acid and undergoes a complex self-processing pathway that results in gene expression changes when the protein accumulates in cells. Here, we report that PEG10 has selectivity for binding U/G-rich RNAs and influences widespread gene expression changes. PEG10 overexpression mimics the loss of TDP-43 in broad changes to gene expression, including dysregulation of mRNA splicing pathways. Specific changes to mRNA splicing were largely unique between TDP-43 knockdown and PEG10 overexpression, as classic TDP-43 targets including STMN2 were not altered by PEG10. Instead, we identified a unique role for PEG10 in regulating splicing of neuregulin 3 (NRG3), a ligand for the neuronal receptor ERBB4. In SH-SY5Y cells and in human neurons overexpressing PEG10, NRG3 protein levels were decreased along cellular processes, suggesting that these cells are less competent at signaling through the NRG3/ERBB4 axis. Using human patient data, we observed similar changes to NRG3 splicing in UBQLN2-mediated ALS, where PEG10 is accumulated, as well as in some cases of sporadic ALS. In conclusion, the retroelement-derived gene PEG10 plays an unexpected role in regulating splicing of neuronal transcripts, which mimics some of the transcript changes observed in human ALS patient samples. Ultimately, this work has implications for the study of PEG10, and mRNA splicing in neurological diseases associated with elevated PEG10 abundance.\n\nID: 42234776\nTitle: Cryptic splicing in synaptic and membrane excitability genes links TDP-43 loss to neuronal dysfunction.\nAbstract: TAR DNA binding protein 43 (TDP-43) pathology is a defining pathological hallmark of multiple neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). A major feature of TDP-43 pathology is its nuclear depletion, leading to the aberrant inclusion of cryptic exons during RNA splicing. STMN2 and UNC13A have emerged as prominent TDP-43 splicing targets, but the broader impact of TDP-43-dependent cryptic splicing on neuronal function remains unclear. Here, we report previously unidentified TDP-43 splicing targets critical for membrane excitability and synaptic function, including KALRN, RAP1GAP, SYT7, and KCNQ2. Using human stem cell-derived neurons, we showed that TDP-43 reduction induces cryptic splicing and down-regulation of these genes, resulting in impaired excitability and synaptic transmission. In postmortem brains from patients with FTD, these cryptic splicing events occurred selectively in neurons with TDP-43 pathology. Suppressing individual cryptic splicing events using antisense oligonucleotides partially restored neuronal function, and combined targeting almost fully rescued the synaptic deficit caused by TDP-43 loss. Together, our findings provide evidence that cryptic splicing in these synaptic and membrane excitability genes is not only a downstream marker but instead a direct driver of neuronal dysfunction, establishing a mechanistic link between TDP-43 pathology and neurodegeneration in ALS and FTD.\n\nID: 42199099\nTitle: Activin A in the central nervous system: Mechanistic and therapeutic insights unveiled by emerging technologies.\nAbstract: Activin A exhibits both protective and pathological roles in the central nervous system, reflecting a functional duality that complicates its therapeutic development. To decipher the underlying mechanisms responsible for these contradictions, we leverage emerging technologies that establish comprehensive cellular and spatiotemporal contexts for its signaling pathway. These approaches elucidate the mechanisms underlying central nervous system diseases and their potential therapeutic applications. In this review, we demonstrate how these advanced technologies enhance our understanding of the mechanism of activin A: CRISPR-based editing validates critical receptors such as ACVR1B in the process of remyelination; organoid and organ-on-a-chip systems model human-specific cellular interactions; spatial and single-cell multi-omics delineate expression and communication networks; and optogenetics/chemogenetics enable precise spatiotemporal control of signaling pathway activity. This technological toolkit provides a robust framework for elucidating the context-specific roles of activin A in conditions such as ischemic stroke, neurodegenerative diseases, glioma, epilepsy, and traumatic brain injury, encompassing key processes including neuroprotection, inflammation, and repair. Furthermore, these mechanistic insights inform next-generation interventions, including adeno-associated virus-mediated gene therapy for localized modulation and advanced nanodelivery systems for targeted biologic transport. Given these capabilities, artificial intelligence plays a crucial role in designing blood-brain barrier-permeable ligands and optimizing smart nanocarriers. By contrasting preclinical data with the clinical pipeline, which currently emphasizes peripheral diseases, we propose that integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement.\n\nID: 42192558\nTitle: Exosome-mediated gut-brain axis signaling in neurodegenerative diseases: Mechanisms, experimental evidence, and therapeutic perspectives-A narrative review.\nAbstract: The stomach and the brain are connected by a sophisticated two-way communication mechanism called the gut-brain axis. Extracellular vesicles, particularly exosomes, that move bioactive substances between the stomach and the brain, such as proteins, lipids, metabolites, and microRNAs, may improve the gut-brain axis. In the past years, the role of exosome-mediated communication has been recognized as significant in relation to the etiology, continued progression, and potential treatment of neurodegenerative disorders. The authors of this review article present a summary of the current understanding of the relationship of gut microbiome, exosome biogenesis, and the pathophysiological development of neurodegenerative diseases. Evidence from laboratory studies, animal studies, and newly emerging human studies suggests that microbiome-based metabolites and inflammatory mediators may modulate how exosomes are produced, what they carry, and how they interact with the blood-brain barrier. These exosomal signals may impact neuroinflammation, neuronal signaling, and the spread of pathological proteins of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease. In addition, they examine some possible ways to target the gut-brain axis from a therapeutic perspective, including manipulating the gut microbiome, providing probiotics and/or prebiotics, performing fecal microbiota transplantation, and/or using engineered extracellular vesicles as vehicles for drug delivery. The authors also outline some of the methodological differences that make it difficult to assess the effects of exosomes.\n\nID: 42181874\nTitle: An integrative neuropharmacological review of Huntington's disease challenges and the role of novel formulations in addressing pharmacological\u2012pharmaceutical limitations.\nAbstract: Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by CAG repeat expansion in the huntingtin gene, leading to progressive neuronal dysfunction and neurodegeneration. Although classically defined as a brain-restricted disorder marked by striatal and cortical degeneration, increasing evidence suggests HD as a multisystem disease involving both central and peripheral pathological alterations. This review aims to provide an integrated overview of neuronal and non-neuronal mechanisms underlying HD, focusing on systemic alterations that influence disease onset, progression, and clinical variability. This review also aims to connect neuropharmacology with pharmaceutical formulation strategies, particularly emphasizing the therapeutic and drug-delivery challenges and nanotechnology-based solutions. A structured literature review was conducted using databases including PubMed, EMBASE, and Scopus. Using the appropriate keywords, original articles, clinical studies, systematic reviews, meta-analyses, and high-quality reviews were selected based on their relevance to HD pathophysiology and therapeutic strategies. HD manifests with motor, cognitive, and psychiatric disturbances; however, this review highlights that peripheral immune activation, gut microbiota dysbiosis, and multiorgan pathology are not merely secondary features but interact with neural circuits, contributing to disease heterogeneity and progression. Current therapeutic approaches are largely symptomatic, achieving minimal effectiveness in disease modification due to challenges such as poor blood-brain barrier penetration, limited target selectivity, and inter-individual variability. New strategies, such as nanotechnology-based drug delivery systems, biologics, and gene editing tools, offer advantages and support a deeper understanding of therapeutic limitations and disease mechanisms, yet their translational applicability remains constrained by limited clinical validation, safety concerns, and scalability problems. Reconceptualizing HD as a multisystem disorder provides a more comprehensive framework for therapeutic development. Integrating central and peripheral disease mechanisms with advances in targeted drug delivery and patient stratification approaches, such as sex differences, hormonal influences, and environmental factors, is essential for translational progress toward personalized therapeutic approaches. Future research should prioritize interdisciplinary approaches to bridge the gap between mechanistic discoveries and effective disease-modifying interventions.\n\nID: 42178983\nTitle: Protein Disulfide Isomerase Disassembles TDP-43/G3BP1 Condensates and Antagonizes TDP-43 Pathological Aggregates.\nAbstract: Cytoplasmic mislocalization and aggregation of transactive response DNA-binding protein-43 (TDP-43) is a common pathological feature of amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration, and Alzheimer's disease with TDP-43 pathology (AD-TDP); the exact role of protein disulfide isomerase (PDI), an enzyme with chaperone activity, in modulating the pathological behavior of TDP-43 is unknown. In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target.\n\nID: 42135847\nTitle: TDP-43: [GU]-ardian of the transcriptome.\nAbstract: TDP-43 is a ubiquitously expressed, primarily nuclear DNA/RNA-binding protein implicated in neurodegenerative diseases including amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD). In this review, we examine the structure and regulation of TDP-43, how these features influence its localization and functional activity, and how their disruption may contribute to disease. Among TDP-43's diverse functions, splicing repression of nonconserved RNA sequences termed cryptic exons has emerged as especially central to human disease. TDP-43 nuclear depletion and cytoplasmic aggregation are well-established pathological features in affected neurons and glia of neurodegenerative diseases, and accumulating evidence suggests that loss of TDP-43-mediated splicing repression occurs presymptomatically in disease. Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction. Here, we synthesize current knowledge of TDP-43 biology and curate datasets from human tissues and experimental models, focusing on cryptic splicing to provide a resource for leveraging cryptic exon biology to better understand, detect, and target TDP-43 dysfunction.\n\nID: 42135750\nTitle: Maintenance and disruption of the physiological dimer structure of TDP-43 in amyotrophic lateral sclerosis and frontotemporal lobar degeneration.\nAbstract: Transactive response DNA-binding protein of 43\u00a0kDa (TDP-43) is an essential regulator of RNA metabolism, playing a pivotal role in splicing, transport, and stability. While its cytoplasmic aggregation is the pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD), recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure. Under healthy conditions, TDP-43 forms dimers via its N-terminal domain, a configuration that is crucial for its nuclear solubility and cooperative RNA binding. In this review, we propose the \"Molecular Zipper\" hypothesis to describe the maintenance of TDP-43 structural homeostasis. In this framework, the N-terminal domain acts as a stabilizing \"NTD-mediated anchor\" that keeps the protein in a functional, \"zipped\" dimeric state, effectively sequestering its aggregation-prone C-terminal regions. Pathogenic triggers-including genetic mutations, aberrant post-translational modifications such as phosphorylation and acetylation, and environmental stressors-can \"unzip\" this structure, leading to the formation of pathogenic monomers. These pathogenic monomers show increased propensity for cytoplasmic mislocalization and recruit wild-type protein into aggregates through a prion-like seeded aggregation mechanism, culminating in nuclear functional loss and cytoplasmic gain-of-toxicity. We further evaluate the emerging diagnostic landscape, focusing on methods to monitor the dimer-to-monomer ratio. Integrating prior biochemical data on TDP-43 dimerization with structural modeling enables a more coherent account of the transition from the physiological dimer to pathological conformers. The Molecular Zipper framework offers a conceptual foundation for reconciling existing experimental findings and for guiding future studies on early structural changes in TDP-43 proteinopathy.\n\nID: 42108387\nTitle: Rational Design and Optimisation of CRISPR-Cas9 Delivery Systems for Targeted Genomic Transformation.\nAbstract: The CRISPR-Cas9 genome-editing technique offers a promising therapeutic strategy for genetic disorders, including neurodegenerative diseases like Alzheimer's disease (AD), characterised by inherited susceptibility and progressive cognitive decline, as well as other hallmarks such as amyloid beta (A\u03b21-42) plaques and neurofibril tangles (NFTs). However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation. This comprehensive review compares various CRISPR-Cas9 delivery vectors, viral, nonviral and physical, with a focus on their efficacy in neurological diseases such as AD. Viral vectors viz., adeno-associated viruses (AAVs) and lentiviruses (LVs) demonstrate high transduction efficiency and BBB permeability. AAVs are preferred for their low immunogenicity, minimal toxicity, high neuronal tropism and episomal persistence, enabling sustained expression without insertional mutagenesis. LVs offer larger genetic payloads but raise concerns about genomic integration and potential oncogenesis, though integration-defective variants mitigate these risks. Nonviral vectors, including peptide and polymer-based nanoparticles, lipid nanoparticles (LNPs) and Inorganic carriers such as gold and silver nanoparticles, are less immunogenic and easier to handle but require further optimisation for in\u00a0vivo BBB crossing and endosomal escape. Physical methods such as electroporation and microinjection are suitable for in\u00a0vitro/ex vivo use, while novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis. These preclinical studies show that these technologies can successfully edit genes and provide therapeutic benefits, including amyloid reduction and cognitive improvement in AD models. Yet off-target effects, immune responses and regulatory hurdles persist. Overall, continuous innovation in delivery vector design and safety profile-targeting strategies is crucial for advancing CRISPR-Cas9 towards clinical therapies for AD-based therapies and related neurological disorders.\n\nID: 42094003\nTitle: Gasdermin D-driven pyroptosis in sepsis: mechanisms, therapeutic strategies, and clinical translation.\nAbstract: Sepsis is a life-threatening organ dysfunction that leads to 11 million annual global deaths. It is characterized by severe immune dysregulation, with gasdermin D (GSDMD)-driven pyroptosis recognized as a key pathogenic mechanism. After exposure to pathogen-associated molecular patterns (PAMPs)/damage-associated molecular patterns (DAMPs), GSDMD, activated via the canonical (caspase-1) and non-canonical (caspase-4/5/11) pathways, forms plasma membrane pores, induces cell lysis, and triggers multi-organ injury. Specifically, GSDMD pores trigger lung inflammation via alveolar macrophage pyroptosis, induce hepatic high mobility group box 1 protein (HMGB1) release, perpetuate bacteremia, cause renal microthrombosis, and disrupt the blood-brain barrier. GSDMD drives both the hyperinflammatory phase (via cytokine storm, NETosis) and the immunosuppressive phase (via lymphocyte apoptosis, T-cell exhaustion), thereby defining hyperinflammatory (GSDMD-NT >120 ng/mL) and immunosuppressive (intestinal barrier failure) endotypes. Promising therapeutic agents include disulfiram (blocking Cys191 oligomerization), anti-GSDMD mAb26.5 (decreasing mortality to 30%), and the combination of imipenem and disulfiram. Clinical translation faces challenges in terms of biomarker validation, organ-specific delivery, and phase-adapted intervention. Future research directions include AI-based drug design, exosome-mediated CRISPR knockout, clinical trials on drug repurposing, and single-cell omics-integrated stratified immunotherapy.\n\nID: 42083963\nTitle: Advances in Microneedle Technology for Targeted Therapy in Alzheimer's and Parkinson's Disease.\nAbstract: The fourth major cause of death worldwide is Neurodegenerative Diseases (NDs), including Alzheimer's and Parkinson's disease. The existing therapies have only a small effect on alleviating symptoms, mainly because the therapeutic agents are difficult to cross the bloodbrain barrier. The purpose of the review is to discuss the potential of microneedle-based transdermal delivery systems to improve the delivery of drugs to the central nervous system and thereby manage neurodegenerative diseases effectively. The article summarizes and synthesizes the available literature that targets the strategies of microneedle-mediated drug delivery. The literature on the design, composition, pharmacokinetics, and mechanistic benefits of different microneedle platforms for surmounting central nervous system barriers was identified and thematically synthesized. Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier. Micro-needles can be used to deliver small molecules, peptides, and nanoparticles to the brain, thereby avoiding systemic side effects and enhancing drug bioavailability. Some of those designs include dissolving, coated, hollow, hydrogel-forming, and stimuli-responsive microneedles, which have been shown to target the brain and exhibit higher therapeutic efficiency in preclinical models. Although technological advances have improved, the clinical translation of microneedlebased strategies remains limited. The future directions could include using microneedles with stem cell-based therapies, CRISPR/Cas9 gene editing, artificial intelligence-based delivery systems, and responsive release technology to facilitate customized treatment. The Microneedle-based drug delivery systems are promising in overcoming the current limitations in the treatment of neurodegenerative diseases. Nonetheless, a large-scale clinical validation is necessary to guarantee safety, efficacy, and scalability to be applied to real-life scenarios.\n\nID: 42074341\nTitle: Pompe Disease: Pathogenesis, Molecular Mechanisms, Neurological Aspects, Diagnostics and Modern Therapeutic Approaches.\nAbstract: Pompe disease (PD) is a neuromuscular autosomal recessive disorder caused by mutation in the GAA gene, which encodes acid \u03b1-glucosidase (GAA), an enzyme responsible for hydrolyzing glycogen to glucose. Deficiency of this enzyme leads to pathological accumulation of glycogen in almost all tissues of the body, with the most pronounced effects in cardiac and skeletal muscle, as well as in the central nervous system. Two major clinical forms of PD are recognized: infantile-onset PD, characterized by almost complete absence of GAA activity and severe cardiomyopathy and neurological abnormalities, and late-onset PD, which primarily presents with impairment of respiratory and motor function. Since 2006, enzyme replacement therapy with recombinant GAA has been used to treat PD, improving survival and quality of life. However, this approach has several limitations: the need for lifelong infusions, the risk of immune responses, and the inability of the enzyme to cross the blood-brain barrier, which is particularly critical for infantile-onset PD. Consequently, alternative strategies are being developed, including gene therapy using adeno-associated virus vectors for GAA delivery to target tissues; these approaches are currently in phase I/II clinical trials. Transplantation of genetically modified hematopoietic stem cells also represents a promising therapeutic strategy, offering a single-intervention treatment with long-lasting effects. This review discusses the molecular mechanisms of PD, current and emerging disease models, and therapeutic approaches, which together open prospects for the development of potentially one-time curative treatments, despite persistent challenges such as immunogenicity and the need for long-term efficacy monitoring.\n\nID: 42074014\nTitle: CRISPR Applications in Alzheimer's Disease: From High-Throughput Genetic Screening to Precision Editing and CNS Delivery.\nAbstract: Alzheimer's disease is a devastating progressive neurodegenerative disorder characterized by extracellular amyloid-beta plaques and intracellular tau tangles. Despite recent advancements in amyloid-beta-targeting immunotherapies, achieving safe and definitive disease control remains a profound clinical challenge. The CRISPR/Cas9 system has emerged as a powerful technology for precision neurogenetics, offering significant potential to address the fundamental questions behind Alzheimer's disease. This comprehensive review delineates the trajectory of CRISPR applications in Alzheimer's disease research and therapeutics. First, we explore the integration of CRISPR in engineering high-fidelity in vitro models, such as isogenic induced pluripotent stem cells and three-dimensional cerebral organoids, alongside advanced in vivo mammalian models. Second, we examine how these platforms facilitate unbiased high-throughput genetic screening to uncover molecular underpinnings regulating tau, lipid metabolism, and neuroinflammation. Third, we critically evaluate precision editing strategies targeting core risk genes (APP, MAPT, APOE, and TREM2), explicitly highlighting the severe physiopathological trade-offs between therapeutic efficacy and loss-of-function toxicity. Finally, we address the ultimate translational bottlenecks impeding clinical application. By dissecting the packaging limits of adeno-associated viral vectors and the physical barricade of the blood-brain barrier, we underscore the necessity of transitioning toward next-generation base editors and non-viral lipid nanoparticles to realize safe and efficacious in vivo clinical gene therapies against Alzheimer's disease.\n\nID: 42041587\nTitle: Gene Editing Strategies for Neurological and Mental Disorders: Advances in Delivery, Methodology, and Clinical Translation.\nAbstract: Neurological and mental disorders are among the main causes of disability worldwide, affecting over three billion people and increasing the socioeconomic burden. Advances in molecular genetics and genome engineering have led to gene-targeted therapies that address root causes rather than just symptoms. This review covers current genome-editing tools, including CRISPR/Cas, base editing, and prime editing. The focus is on the benefits of gene editing in the central nervous system, where post-mitotic neurons allow lasting effects after a single treatment. It also discusses emerging delivery platforms such as viral vectors, nanoparticles, and exosome systems, as well as methods to bypass the blood-brain barrier. Recent clinical progress in spinal muscular atrophy, Parkinson's disease, Huntington's disease, and Alzheimer's disease is highlighted, with promising preclinical results for autism, bipolar disorder, epilepsy, and other neurogenetic conditions. The review concludes with regulatory issues, market trends, and ongoing clinical trials, underscoring the potential of gene therapies to transform disease management and provide long-term solutions.\n\nID: 42018247\nTitle: A deep dive into ferritin nanoparticle advancements: experimental and computational perspectives.\nAbstract: Ferritin, a natural iron-storage protein, has emerged as a versatile platform in nanotechnology and biomedicine due to its biocompatible 12\u00a0nm nanocage, intrinsic targeting via the transferrin receptor 1, and adaptability for diverse applications. This review integrates recent experimental and computational advances in ferritin-based nanoparticles, Ferritin is used for drug delivery, vaccine delivery, gene therapy, imaging and diagnostics, antioxidant therapy, and anti-inflammatory and neuroprotective therapies. Experimentally, ferritin nanocages achieve high-capacity loading (up to 400 molecules per cage) of therapeutics such as doxorubicin, siRNA, and CRISPR-Cas9 through pH-responsive disassembly, passive diffusion, and engineered self-assembly. Its natural TfR1 affinity enables precise tumor targeting and blood-brain barrier penetration, improving outcomes in cancers, infectious diseases, and neurological disorders. Computationally, molecular dynamics simulations predict stable antigen-ferritin interfaces. Density functional theory elucidates metal-oxide interactions in catalytic nanozymes. Machine learning classifiers leverage ferritin biomarkers for iron deficiency anemia detection, and bioinformatics tools like weighted gene co-expression network analysis and protein-protein interaction networks reveal ferritinophagy mechanisms in neurodegeneration and cancer. Docking-guided designs enhance vaccine epitope exposure and PROTAC degradation efficiency, fostering precision diagnostics and sustainable nanocarrier optimization. Despite promising preclinical results, challenges in scalability, long-term immunogenicity, and regulatory validation persist. This review highlights ferritin's revolutionary potential in nanomedicine, proposing future directions for AI-assisted design, personalized therapies, and sustainable nanotechnology to overcome barriers for clinical use.\n\nID: 42013476\nTitle: Cryptic Splicing in ALS: From Driving Disease Progression to Unlocking Novel Therapeutics.\nAbstract: TDP-43 is an RNA-binding protein that regulates multiple aspects of RNA processing, and its mislocalization from the nucleus to the cytoplasm is a defining feature of amyotrophic lateral sclerosis (ALS). While both loss- and gain-of-function mechanisms contribute to disease, the discovery of cryptic splicing has shed light on the downstream consequences of TDP-43 nuclear clearance for neuronal health. Here, we highlight how loss of nuclear TDP-43 can drive a cascade of events that lead to the impairment of cellular proteostasis and result in a positive feedback loop that perpetuates neuronal dysfunction. This sustains the appearance of cryptic splicing events in genes that are involved in key pathways for the maintenance of axonal homeostasis and synaptic transmission. In contrast to their detrimental effects on neuronal health, cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies.\n\nID: 42010065\nTitle: Recent advances in lipid and biomimetic nanocarriers for nucleic acid delivery in glioblastoma.\nAbstract: Glioblastoma (GBM) remains uniformly lethal due to diffuse invasion, extensive molecular heterogeneity, and a profoundly immunosuppressive microenvironment. Nucleic-acid therapeutics\u2014including antisense oligonucleotides, RNA interference, messenger RNA, and CRISPR-based genome editing\u2014offer programmable control over oncogenic drivers and immune pathways, yet their clinical translation is hindered by rapid nuclease degradation, systemic clearance, restricted blood\u2013brain-barrier transport, inefficient cellular uptake, and endosomal entrapment. Recent progress in nanotechnology has enabled the rational design of nanoparticle platforms that overcome these multilayered biological obstacles. This review summarizes advances (2022\u20132025) in lipid and biomimetic nanocarriers engineered to enhance nucleic-acid delivery for GBM therapy. For instance, ionizable lipid nanoparticles with pH-responsive chemistry and optimized head-group design achieve efficient cytosolic release with improved biocompatibility, while biomimetic systems, such as cell-membrane-, lipoprotein-, virus-, DNA-, and exosome-mimicking platforms, leverage natural transport and recognition pathways for tumor-specific targeting and immune evasion. Finally, we discuss translational considerations, including GMP-compatible manufacturing, batch consistency, long-term safety and immunogenicity, and advanced model selection, and outline future opportunities in high-throughput lipid discovery, AI-assisted ligand design, hydrogel-mediated spatiotemporal release, and patient-tailored nanotherapies. Collectively, these emerging nanocarriers offer a convergent strategy to navigate physiological barriers and advance precision nucleic-acid therapeutics against glioblastoma.\n\nID: 41997082\nTitle: Translational advances of exosomes in neurodegeneration towards precision healthcare: From biomarkers to therapeutic frontiers.\nAbstract: Exosomes are nanoscale extracellular vesicles (EVs) that mediate intercellular communication and carry proteins, lipids, mRNAs, and non-coding RNAs reflective of their parental cells. Their biogenesis, molecular composition, and ability to traverse physiological barriers, including the blood-brain barrier, position exosomes as powerful candidates for biomarker development and therapeutic delivery in neurodegenerative diseases (NDDs). In Alzheimer's disease, Parkinson's disease, multiple sclerosis, and prion disorders, exosomes not only mirror pathological processes but actively participate in the propagation of misfolded proteins and neuroinflammatory signals through cell-type-specific vesicle subpopulations. This review synthesises current advances in exosome biology, cargo sorting, release mechanisms, and pathophysiological roles in the central nervous system, with emphasis on how neuron-, astrocyte-, and microglia-derived exosomes diverge in their cargo profiles and functional consequences across diseases. We highlight disease-specific exosomal signatures, including amyloid-\u03b2 (A\u03b2), tau, \u03b1-synuclein, myelin proteins, prion proteins (PrP) and regulatory microRNAs. We evaluate emerging technologies such as microfluidic isolation, single-vesicle analysis, and multi-omics profiling that are accelerating biomarker discovery, and review exosome-based therapeutic strategies, including native stem cell-derived exosomes and surface-engineered vesicles loaded with neuroprotective miRNAs, small molecules, and gene-editing cargo. We address critical unmet challenges in translating these approaches to the clinic, including scalable and standardised production, incomplete pharmacokinetic /pharmacodynamic characterisation in preclinical models, immunogenicity and off-target safety concerns, and the absence of specific regulatory guidance for EV drug products. Together, these insights highlight the transformative potential of exosomes as both precision diagnostic tools and disease-modifying therapeutic platforms for NDDs.\n\nID: 41996987\nTitle: Decoding RNA splicing pathology: Alternative splicing in amyotrophic lateral sclerosis and its therapeutic potential.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder marked by progressive motor neuron loss, leading to muscle weakness, paralysis, and respiratory failure. Dysregulation of RNA metabolism and splicing has emerged as a central mechanism in ALS pathogenesis. TARDBP (TAR DNA-binding protein), FET family proteins (FUS, EWSR1, TAF15), SOD1 (Superoxide Dismutase 1), and C9orf72 (Chromosome 9 Open Reading Frame 72) are key genes associated with ALS that regulate RNA processing, alternative splicing, and nuclear-cytoplasmic transport. Mutations or mislocalization of these proteins result in nuclear loss-of-function and cytoplasmic gain-of-function toxicity, promoting protein aggregation, sequestering spliceosomal components, and impairing spliceosome assembly. This leads to the aberrant inclusion of cryptic exons in essential neuronal genes, such as STMN2 (Stathmin 2) and UNC13A (Unc-13 Homolog A), resulting in the production of truncated proteins, defective axonal maintenance, and impaired synaptic function. TDP-43 pathology, a hallmark of ALS, disrupts splicing and RNA transport, while C9orf72 repeat expansions and FET protein mutations exacerbate cytoplasmic aggregation and stress granule dynamics. Mutant SOD1 contributes via mitochondrial dysfunction, endoplasmic reticulum stress, and disrupted axonal transport. Therapeutic strategies targeting these mechanisms are advancing rapidly. Gene replacement therapy, which restores STMN2 expression, and antisense oligonucleotides (ASOs) targeting mutant transcripts show promise in preclinical and early clinical studies. Complementary approaches, including the inhibition of stress kinases and the activation of autophagy, reduce cytoplasmic protein aggregation and support neuronal homeostasis. This review provides a comprehensive overview of RNA splicing regulation, spliceosomal dysfunction, and cryptic exon incorporation in ALS. Understanding the interplay among splicing defects, RNA-binding protein pathology, and neuronal degeneration is critical for developing next-generation multimodal therapies to restore RNA processing, reduce toxic protein accumulation, and promote motor neuron survival.\n\nID: 41993496\nTitle: Nuclear export modulates TDP-43 phase transition and cytoplasmic aggregation.\nAbstract: RNA-binding protein TAR DNA-binding protein 43 (TDP-43) can form liquid-like, nuclear assemblies whose phase behavior may influence its aggregation propensity and neurotoxic activity. The mechanism(s) that modulates the transition of TDP-43 from a liquid to solid phase is poorly defined. Here we combine chemical and genome-wide genetic screenings to identify cellular factors that modulate the phase behavior of an RNA-binding defective TDP-43 mutant that mimics an Amyotrophic Lateral Sclerosis (ALS)-associated variant. Our screens uncover multiple cellular processes including RNA splicing, protein translation, proteostasis imbalance and nuclear export as TDP-43 phase regulators. Importantly, TDP-43 phase transition can be dynamically recapitulated in vitro in a semi-permeabilized cell system, which reveals that the inhibition of nuclear export reshapes the nuclear environment in favor of an RNA-dependent TDP-43 liquid-liquid phase separation (LLPS) state, which mitigates cytoplasmic TDP-43 aggregation. We validated this mechanism in a brain organoid model bearing an ALS-associated mutation, showing that nuclear export deficiency can limit pathogenic phospho-TDP-43 accumulation. These findings establish nuclear export as a key regulator of TDP-43 phase transitions and define a mechanistic framework that links altered nuclear transport and phase dynamics to TDP-43 aggregation potential.\n\nID: 42393685\nTitle: Structural-functional network decoupling in early stage amyotrophic lateral sclerosis reveals cell-type specific transcriptional signatures.\nAbstract: Amyotrophic lateral sclerosis (ALS) involves widespread brain network dysfunction, yet the molecular mechanisms linked to these alterations remain poorly understood. We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology.\n\nID: 42384931\nTitle: Real-time Targeted Enrichment in Single-cell Long-read Sequencing.\nAbstract: The vast majority of multi-exonic genes are alternatively spliced, generating diverse and cell-type-specific isoforms exhibiting functional differences. To better capture this heterogeneity using single-cell long-read sequencing data, we previously developed an exome-probe-based approach to enrich for exonic reads of target genes. While effective, this procedure is time-consuming and expensive. Real-time targeting offers a more cost-efficient solution for selectively sequencing reads of interest. Here, we performed real-time enrichment of exonic sequences of single-cell long reads by targeting spliced transcripts from 3377 genes implicated in brain functions and related diseases. Our approach increased the total number of spliced on-target reads to up to 1.82 times the control level. Notably, targeting lowly expressed subsets yielded spliced on-target reads 1.39 to 1.89 times the control. While these gains do not rival those achieved using chemical probe-based enrichment, they are sufficient to significantly enhance the power of downstream statistical analyses, such as testing for cell-type-specific isoform abundance. Specifically, compared to na\u00efve single-cell long-read sequencing, our approach yielded 2.42 times as many genes with significant differences in isoform usage between neurons and glia. Real-time targeting confirms cell-type-specific splicing in two early Mapt exons and newly reveals such events in\u2009>\u2009100 genes, including Bak1 and Atp8a1. Overall, our findings highlight real-time targeting as a versatile method for enhancing resolution in detecting differential isoform usage across cell types in single-cell long-read data, offering the potential to obtain a fuller view of cellular isoform diversity.\n\nID: 42256007\nTitle: A Primary Open-Angle Glaucoma Locus Near Transcription Factor PRRX1 Identified in the Million Veteran Program.\nAbstract: To identify genetic risk variants for primary open-angle glaucoma (POAG) and prioritize biologically relevant genes through integration of genetic association, regulatory annotation, ocular transcriptomics, and functional modeling. A case-control genome-wide association study (GWAS) with integrative functional follow-up. A total of 234 153 United States Veterans of European ancestry enrolled in the Million Veteran Program, including 10 738 POAG cases and 223 415 controls. We conducted a POAG GWAS using electronic health record-based phenotyping and logistic regression adjusted for age, sex, and genetic ancestry. Genome-wide significant loci were evaluated using statistical fine-mapping and colocalization with expression and splicing quantitative trait loci across ocular and nonocular tissues. Bulk and single-cell transcriptomic datasets were interrogated to assess gene expression in glaucoma-relevant tissues and cell types. Functional relevance was evaluated by examining gene expression responses to cyclic mechanical stretch (CMS) with and without transforming growth factor beta 2 (TGF\u03b22) in primary human trabecular meshwork (HTM) cells. Ortholog expression was assessed in zebrafish. Genome-wide significant variant associations with POAG, colocalized regulatory signals, ocular tissue and cell-type expression patterns, and differential gene expression under biomechanical and profibrotic stress conditions. Genome-wide association study identified a significant association near PRRX1 (lead variant rs10919469:G; odds ratio \u2248 0.92; P value = 1.9 \u00d7 10-8) that replicated in FinnGen and UK Biobank. Fine-mapping yielded a 95% credible set of 25 variants without a single high probability causal variant. Although regulatory annotation implicated multiple genes, PRRX1 showed broad expression across glaucoma-relevant ocular tissues and cell types, including trabecular meshwork and optic nerve head fibroblasts, pericytes, and astrocytes. In primary HTM cells, PRRX1 was significantly downregulated under combined CMS and TGF\u03b22 exposure. Zebrafish ortholog analyses support neuro-ocular relevance. Integration of GWAS, regulatory annotation, ocular transcriptomics, and functional modeling prioritizes PRRX1 as a plausible gene of interest warranting further investigation for potential involvement in POAG. Identification and integrative evaluation of this POAG-associated locus advances understanding of disease biology and may inform future risk stratification and therapeutic investigation.

We conduct multi-ancestry transcriptome-wide association studies (TWAS) to discover potential breast cancer susceptibility genes. We develop ancestry-specific genetic models to predict levels of gene expression, alternative splicing, and 3' UTR alternative polyadenylation using genomic and transcriptomic data from 652 normal female tissue samples and apply these models to GWAS data of 178,534 cases and 248,300 controls for association analyses. We identify 290 genes associated with breast cancer risk, including 103 previously unreported and 46 not located at known GWAS loci, and 39 genes show distinct associations with breast cancer risk by estrogen-receptor status. Single-cell RNA sequencing and in vitro experiment data provide additional functional evidence for 169 genes. These genes are enriched in pathways implicated in breast carcinogenesis. Our study uncovers insights into breast cancer genetics and biology.\n\nID: 42183628\nTitle: CHCHD2 and CHCHD10 promoted autophagic clearance of protein aggregates via GABARAPs.\nAbstract: Mutations in mitochondrial protein CHCHD2 and its paralog CHCHD10 were identified in patients with Parkinson disease (PD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD) or Alzheimer disease (AD). CHCHD2 and CHCHD10 mutations caused neurodegeneration in model animals as seen in patients, but their pathophysiological roles remain elusive. Here we reported a direct role of CHCHD2 and CHCHD10 in autophagy. We identified a protein complex composing of CHCHD2-CHCHD10-C1QBP/p32-Atg8-family proteins (ATG8s), in which each molecule interacted with another. CHCHD2, CHCHD10 and C1QBP/p32 associated with ATG8s, preferentially, GABARAPs. Disease-associated CHCHD2 and CHCHD10 mutations exhibited varied interaction with ATG8s. By binding to GABARAPs, CHCHD2 and CHCHD10 underwent autophagic degradation, and recruited the ULK1 complex. Autophagy initiation defects occurred upon transient knockdown of CHCHD2, and also in human iPSC-derived CHCHD2-/- or CHCHD2T61I dopaminergic neurons. Importantly, CHCHD2 and CHCHD10 promoted autophagy. CHCHD2 reduced protein aggregates in cells and toxic SNCA/\u03b1-synuclein species in mouse striatum. Our study thus revealed mitochondrial proteins CHCHD2 and CHCHD10 as both autophagy substrates and autophagy activators and laid groundwork for therapy targeting patients with neurodegeneration.Abbreviations: AA: amino acid; AD: Alzheimer disease; ALS: amyotrophic lateral sclerosis; ATG5: autophagy related 5; ATG7: autophagy related 7; ATG8: mammalian Atg8-family protein; ATG13: autophagy related 13; bafA1: bafilomycin A1; C1QBP/p32/gC1qR/HABP1: complement component 1, q subcomponent binding protein; CHCHD2/MNRR1/MIX17B: coiled-coil-helix-coiled-coil-helix domain containing 2; CHCHD10/MIX17A: coiled-coil-helix-coiled-coil-helix domain containing 10; CHX: cycloheximide; CMA: chaperone-mediated autophagy; CRISPR: clustered regularly interspaced short palindromic repeats; CQ, chloroquine; DA: dopaminergic; DMSO: dimethyl sulfoxide; EBSS: Earle's balanced salt solution; RB1CC1/FIP200: RB1 inducible coiled-coil 1; FTD: frontotemporal dementia; GABARAP: gamma-aminobutyric acid receptorbassociated protein; GABARAPL1: GABA type A receptor associated protein like 1; GABARAPL2: GABA type A receptor associated protein like 2; hESC: human embryonic stem cells; iPSC: induced pluripotent stem cell; KO: knockout; LAMP1: lysosomal-associated membrane protein 1; LAMP2A: lysosomal-associated membrane protein 2A; MAP1LC3/LC3: microtubule-associated protein 1 light chain 3; LIR: LC3-interacting region; PD: Parkinson disease; SQSTM1/p62: sequestosome 1; TARDBP/TDP-43: TAR DNA binding protein; TH: tyrosine hydroxylase; TMR, tetramethylrhodamine; WT: wild type; UB: ubiquitin; ULK1: unc-51 like kinase 1.\n\nID: 42156927\nTitle: HELIX: a scalable model for predicting context-dependent regulation of RNA splicing and isoform usage.\nAbstract: Context-dependent alternative splicing plays a critical role in disease pathogenesis and organ development, but its complex regulation remains challenging to predict. Here, to address this, we developed HELIX, a hierarchical deep learning framework that integrates pre-mRNA sequence and RNA-binding protein expression profiles to predict tissue- and condition-specific splicing patterns and transcript isoform usage simultaneously. By leveraging both short-read and long-read RNA sequencing data during training, HELIX achieves greater accuracy than existing splicing prediction models and conventional short-read-based methods in predicting differential splicing events, splicing strength at highly regulated splice sites, and isoform usage. The model enables systematic identification of tissue-specific splicing quantitative trait loci and their functional impacts. Furthermore, HELIX predicts patient-specific splicing dysregulation with quantitative attribution to genetic variants and abnormal RNA-binding protein expression in colon cancer cohorts. Through transfer learning, the HELIX model can be adapted to single-cell RNA sequencing data, thereby enabling the prediction of cell-type-specific isoforms.\n\nID: 42134565\nTitle: Metabotropic glutamate receptors in the testis: An integrative bioinformatic review of neuroendocrine, reproductive, and Neuropsychopharmacological aspects.\nAbstract: Metabotropic glutamate receptors (mGluRs) are best known for modulating synaptic transmission, yet accumulating evidence shows that they are also widely expressed in peripheral tissues, including the testis. Methodologically, this work integrates a narrative synthesis of the literature with an in-silico bioinformatic analysis of bulk (GTEx) and single-cell (HPA, CellxGene) RNA-seq datasets, aiming to clarify how mGluRs contribute to testicular physiology. After outlining the striking structural and metabolic parallels between brain and testis-tight barrier systems, selenium-dependent redox control, and exceptionally complex alternative splicing-we confirm that several mGluR subtypes are expressed in Sertoli, Leydig, and germ cells. GRM7 and GRM8 emerge as the dominant transcripts during the late stages of spermatogenesis, and their co-expression networks are strongly linked to axoneme assembly, cilium-driven motility, mitogen-activated protein kinase (MAPK) signaling, and spermatid differentiation. These results point to a role for mGluR-dependent, cyclic adenosine monophosphate (cAMP)-sensitive pathways in fine-tuning sperm maturation and motility. We further discuss how mGluR activity interfaces with the hypothalamic- pituitary-gonadal (HPG) axis and local estrogen signaling, highlighting implications for male infertility, novel contraceptive strategies, and the safe therapeutic targeting of mGluRs in neuropsychiatry. Overall, the data reinforce the concept of a brain-testis continuum, in which glutamatergic signaling is pivotal not only to neuronal plasticity but also to spermatogenesis, steroidogenesis, and sperm function.\n\nID: 42131110\nTitle: Single cell Raman spectroscopic profiles predict treatment responses in patients with de novo acute myeloid leukemia.\nAbstract: Leukemia is a clonal malignant proliferative disease originating from hematopoietic stem cells. Although its treatment strategy has gradually developed from traditional chemotherapy to a multimodal treatment system including novel targeted therapy and immunotherapy, primary drug resistance in particular remains the core clinical problem leading to poor patient prognosis. This clinical dilemma indicates that the traditional genotyping system based on genomics has not been able to fully resolve the molecular heterogeneity of acute myeloid leukemia (AML), and it is urgent to establish a precise stratified model that can dynamically reflect the functional status of tumor cells in the initial stage of treatment. In this study, Raman spectroscopy (RS) combined with machine learning algorithm was used to construct a metabolic prognosis prediction model for AML chemotherapy response. Bone marrow single cell Raman spectroscopy data of newly diagnosed AML patients were collected, and the molecular fingerprint was analyzed by principal component analysis linear discriminant analysis (PCA-LDA) and multivariate curve resolute alternating least square method (MCR-ALS). The results showed that the PCALDA model achieved complete remission or non-remission (CR/NR) classification through 24 principal components (cumulative variance contribution of 90.1%), the accuracy of external validation was 94.8% (sensitivity 97.9%, specificity 92.0%), and the AUC reached 96.27%. Protein, lipid, nucleic acid and mixed components were decomposed by MCR-ALS, and lipid and nucleic acid metabolic pathways were enriched in NR group (P < 0.001). Studies have shown that RS single-cell metabolic fingerprint can decode the metabolic reprogramming features associated with chemotherapy resistance in AML, providing a new marker-free and highly sensitive tool for real-time prognostic stratification and targeted intervention.\n\nID: 42119563\nTitle: RegVelo: Gene-regulatory-informed dynamics of single cells.\nAbstract: Cell fate transitions are driven by regulatory circuitry, yet RNA velocity models cellular dynamics without explicitly accounting for gene regulatory interactions, limiting mechanistic insight. Conversely, gene regulatory network (GRN) inference methods largely neglect the dynamic nature of biological systems. To overcome this conceptual disconnect, we present RegVelo, a bottom-up, actionable, and interpretable deep learning framework that jointly models splicing kinetics and gene regulatory interactions. Across diverse biological systems, RegVelo provides reliable predictive power for terminal states, gene interactions, and perturbation simulations. By applying RegVelo to zebrafish neural crest development using full-length Smart-seq3 and shared gene expression and chromatin accessibility measurements, we delineate regulatory programs underlying fate specification. Guided by in silico perturbations and validated by CRISPR-Cas9 knockout and single-cell Perturb-seq, we establish tfec as an early driver and elf1 as a regulator of pigment cell fate. RegVelo establishes a quantitative framework for bridging gene regulation and cell fate decisions.\n\nID: 42051315\nTitle: Statins and genetic inhibition of the mevalonate pathway activate an ATF3-STMN2 regenerative program.\nAbstract: Loss of neuronal regenerative capacity is a common feature of neurodegenerative disease and axonal injury, yet the transcriptional programs governing this state remain poorly defined. Stathmin-2 (STMN2), a tubulin-binding protein essential for axon maintenance and repair, is profoundly depleted following loss of nuclear TDP-43 in neurodegenerative disease. Here, we identify statins as potent inducers of STMN2 expression. Pharmacological and genetic suppression of the mevalonate pathway, and subsequent prevention of protein geranylgeranylation, restored STMN2 levels in TDP-43 deficient cells and promoted neurite growth. STMN2 induction was abrogated when using a statin analogue unable to interact with HMG-CoA reductase, and through co-administration of mevalonate or geranylgeranyl diphosphate substrates. RNA-seq revealed that statins induce a coordinated pro-regenerative transcriptional response, including activation of the AP-1 transcription factor complex gene, ATF3. Loss of ATF3 attenuated STMN2 induction in vitro, and diminished injury-induced Stmn2 upregulation in spinal motor neurons in vivo. These results demonstrate statins as modulators of ATF3 and STMN2 expression and highlight their therapeutic potential in neurodegenerative disease.\n\nID: 41987571\nTitle: QCatch: a framework for quality control assessment and analysis of single-cell sequencing data.\nAbstract: Single-cell sequencing data analysis requires robust quality control (QC) to mitigate technical artifacts and ensure reliable downstream results. While tools like alevin-fry and simpleaf (and augmented execution context for the alevin-fry), offer flexibility and computational efficiency to process single-cell data, this ecosystem will further benefit from a standardized QC reporting tailored for its outputs. We introduce QCatch, a Python-based command-line tool that generates comprehensive and interactive HTML QC reports designed specifically for single-cell quantification results. Taking the output directory of alevin-fry or simpleaf as the input, QCatch is able to perform essential processing steps, like cell calling, and generate detailed QC reports that contain informative visualizations and statistics, including unique molecular identifier (UMI) count distributions, sequencing saturation estimates, and splicing status information, for QC assurance. Built for seamless integration into downstream analysis workflows, QCatch exports the processed results in a richly-annotated H5AD format file, a widely used data format common among many downstream single-cell data analysis tools. The source code and documentation of QCatch are available on GitHub at https://github.com/COMBINE-lab/QCatch. QCatch can be installed via both Bioconda and PyPI.\n\nID: 41964251\nTitle: RNA G-quadruplex-protein interactions: from nuclear RNA processing to cytoplasmic stress response and neurodegeneration.\nAbstract: RNA G-quadruplexes (rG4s) are stable secondary structures formed by non-canonical Hoogsteen base-pairing of guanine-rich sequences in precursor and mature messenger and non-coding RNAs. We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology. We discuss the implications of a dynamic equilibrium of folded and unfolded rG4s in health and disease, with particular focus on their emerging roles in neurodegeneration.\n\nID: 41943580\nTitle: DCPS modulates TDP-43-linked neurodegeneration through P-body-mediated RNA decay.\nAbstract: The proteinopathy of the RNA-binding protein TDP-43, characterized by nuclear clearance and cytoplasmic inclusion, is a hallmark of multiple neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD). Through CRISPR interference (CRISPRi) screening in human neurons, we identified the decapping scavenger enzyme (DCPS) as a novel genetic modifier of TDP-43 loss-of-function (LOF)-mediated neurotoxicity. Our findings reveal that TDP-43 LOF leads to aberrant mRNA degradation via dysregulating the properties and activity of processing bodies (P-bodies). TDP-43 interacts with P-body component proteins, potentially influencing their dynamic equilibrium and assembly into ribonucleoprotein (RNP) granules. Loss of TDP-43 hyperactivates P-bodies, increasing mRNA association and RNA decay. Reducing DCPS restores P-body integrity and RNA turnover, ultimately improving neuronal survival. Overall, this study highlights a novel role of TDP-43 in RNA processing through P-body regulation and identifies DCPS as a potential therapeutic target for TDP-43 proteinopathy-related neurodegenerative diseases.\n\nID: 41909467\nTitle: Exosome-like nanovesicles from acerola for CRISPR-Cas9 ribonucleoprotein delivery to the central nervous system.\nAbstract: An aberrant six-base repeat in intron 1 of C9orf72 is the most frequent cause of solitary and familial amyotrophic lateral sclerosis and frontotemporal dementia. This mutation is a potential target for CRISPR/Cas9-based genome editing. However, the blood-brain barrier and limitations of current viral or nanoparticle-based delivery systems to neurons significantly restrict the clinical application of CRISPR-Cas9 in the brain. To address these challenges, we developed a drug delivery system using acerola-derived exosome-like nanoparticles (AELNs), which may overcome several limitations associated with human exosomes. AELNs stably form complexes with ribonucleoproteins (RNPs) comprised of Cas9 proteins and guide RNAs (gRNAs). We improved the delivery efficiency and selectivity of AELN/RNP complexes in GLP2-receptor-expressing neurons by incorporating GLP2 peptides into the AELN/RNP complexes. Intranasal administration of peptide-tagged AELN/RNP complexes in vivo confirmed the successful genome editing of C9orf72, demonstrating the potential of this system for treating neurodegenerative diseases. This study presents a potentially innovative approach for in vivo genome editing using a noninvasive delivery system.\n\nID: 41904011\nTitle: The quest to restore neuronal structure: Targeting cytoskeletal proteins in neurodegenerative diseases.\nAbstract: Neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis (ALS), and Huntington's disease are characterized by progressive neuronal dysfunction and loss. A growing body of evidence implicates cytoskeletal disruption as a central pathological mechanism in these conditions. Cytoskeletal proteins, including microtubules, actin filaments, tau, neurofilaments, and alpha-synuclein, not only provide structural integrity but also regulate axonal transport, synaptic connectivity, and neuroplasticity. Its dysfunction will lead to impaired intracellular trafficking, protein aggregation, and neuronal degeneration. This chapter explores clearly about the specific cytoskeletal abnormalities that are evident in major neurodegenerative disorders, highlighting the biological mechanisms such as tauopathy-induced microtubule instability in Alzheimer's, actin cytoskeleton dysregulation in Parkinson's, and neurofilament aggregation in ALS. Current therapeutic strategies aimed at the stabilizing cytoskeletal components, enhancing protein clearance, and restoring transport dynamics are examined, alongside the cutting-edge approaches including the gene therapy, CRISPR/Cas9 editing, and nanotechnology-based delivery systems. Challenges such as limited blood-brain barrier penetration, off-target toxicity, and patient heterogeneity are also discussed with the focus on need for precision medicine. Additionally, we have also explored the future directions that specifically focused on the biomarker development, combination therapies, and strategies to promote neuroregeneration and structural plasticity. Targeting cytoskeletal pathways holds significant promise not only for suppressing the disease progression but also for rebuilding the structural foundation of the nervous system, potentially reversing the neurodegenerative decline.\n\nID: 41865126\nTitle: Recent Advances in the Non-viral Delivery of Genes to Central Nervous System Disorders.\nAbstract: Disorders of the central nervous system (CNS), neurological disorders, neurodegenerative disorders, genetic disorders) constitute a significant burden on global health, and current treatment options remain challenging. As treatment for CNS disorders is primarily palliative, the underlying causes of disease progression are not addressed through conventional pharmacologic therapies. Gene therapy has the potential to address these root causes of disease progression; however, many of the vectors used in gene therapy (e.g., adeno-associated viruses (AAVs)) have limitations such as immunogenicity, low cargo capacity, and crossing the blood-brain barrier (BBB). These limitations have led to significant progress in the development of non-viral gene delivery systems. Compared with viral vectors, non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration. This review reports recent advancements in the development of non-viral platforms for CNS gene delivery and focuses on lipid-based nanoparticles, polymeric nanoparticles, exosome-based techniques, and new hybrid technologies. Particular emphasis is placed on nanoparticle modification approaches to enhance BBB penetration and enable delivery of genome-editing technologies (CRISPR/Cas systems). The review provides explanations of clinical trials, regulatory considerations, and manufacturing issues that result from the recent developments noted above. It also explores the emerging role of artificial intelligence in supporting carrier design and enhancing delivery efficiency. Both artificial intelligence and non-viral platforms have the potential to facilitate the advancement of safe, effective, and repeatably administered gene therapies for patients with CNS disorders.\n\nID: 41864145\nTitle: Emerging disease-modifying therapies for Angelman syndrome: A comprehensive review for pediatric neurologists.\nAbstract: Angelman syndrome (AS), a rare neurogenetic disorder affecting approximately 1 in 15,000 live births, results from loss of functional UBE3A gene expression and manifests with severe developmental delay, intellectual disability, absent speech, ataxia, epilepsy, and distinctive behavioral features. Until recently, only symptomatic management was available. This review provides pediatric neurologists with a comprehensive, practice-oriented overview of emerging disease-modifying therapies for AS, focusing on therapeutic approaches advancing through clinical development. The molecular pathophysiology of AS, natural history considerations critical for trial interpretation, and the current evidence for antisense oligonucleotide (ASO) therapies (ION582, GTX-102/apazunersen, rugonersen), gene replacement approaches (MVX-220), and next-generation strategies including CRISPR-based gene editing, artificial transcription factors, small molecules, and novel delivery platforms are reviewed. ASO therapies targeting the UBE3A antisense transcript represent the most clinically advanced approach, with three candidates showing proof-of-concept efficacy in Phase 1/2 studies and two advancing to pivotal Phase 3 trials. Gene replacement therapy offers potential single-administration treatment but faces challenges regarding safety, immune responses, and durability. Next-generation approaches including CRISPR activation, epigenetic editing, and blood-brain barrier-penetrating delivery systems show preclinical promise. Critical challenges include outcome measurement limitations, genotype stratification, long-term safety monitoring, and ensuring equitable access. These advances herald a transformation in AS clinical care and represent a milestone in precision pediatric neurology.\n\nID: 41861112\nTitle: Embedded CRISPRi Enhances Gene-Silencing Efficiency in Drosophila.\nAbstract: CRISPR interference (CRISPRi), leveraging catalytically inactive Cas9 (dCas9), has transformed transcriptional silencing. However, its application in Drosophila melanogaster has been constrained by inconsistent efficiency and limited repression amplitude. Here, we present embedded CRISPR interference (emCRISPRi), an advanced gene-silencing platform that integrates transcriptional repression domains (Mxi and TRD) into a structurally flexible region of dCas9. This design significantly enhances silencing efficiency, enabling robust repression of coding genes and cis-regulatory elements, particularly at transcription start site (TSS)-proximal regions. emCRISPRi demonstrates improved gene-silencing activity compared to RNA interference (RNAi) at several tested loci and facilitates strong phenotypic rescue via unmodified cDNA. Its versatility is demonstrated through the dissection of Hippo pathway interactions and the mitigation of TDP-43-induced neurotoxicity in an amyotrophic lateral sclerosis (ALS) model. These findings position emCRISPRi as a transformative tool for functional genomics, enhancer studies, and disease modeling in Drosophila, with significant potential for cross-species adaptation and therapeutic innovation.\n\nID: 41835941\nTitle: The delivery challenge of adeno-associated virus vector-based gene therapies for neurological diseases.\nAbstract: There is great anticipation that gene therapies can offer solutions to many neurological diseases. Already, much is known about therapeutic targets and how they would need to be manipulated to mitigate disease. For such gene therapies to move to the clinic, potent CNS delivery vehicles are needed. One line of investigation focuses on adeno-associated viruses (AAV) to address this need. In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration. This review will introduce this topic and provide an update on recent developments. First, we describe the physical barriers that must be overcome for AAV-delivered gene therapies to reach target cells in the CNS. We then put a spotlight on the natural AAV9 capsid's inherent propensity to cross the BBB and key lessons learned from its use for delivering a therapeutic payload for the treatment of spinal muscular atrophy. Next, we summarize methods for engineering recombinant AAV (rAAV) capsids with improved brain penetrance, and present in vitro paradigms for predicting their capacity to cross the human BBB. We also present strategies for side-stepping the delivery limitations of existing rAAV vectors. Finally, we point toward a few notable clinical studies whose outcomes may advance our understanding of what rAAV-delivered gene therapies can offer to people afflicted with CNS disorders.\n\nID: 41832177\nTitle: TYK2 mediates neuroinflammation in Alzheimer's disease brains with TDP-43 pathology.\nAbstract: Neuroinflammation is a pathological feature of neurodegenerative diseases like Alzheimer's disease and ALS. Cytoplasmic dsRNA (cdsRNA) triggers a type-I interferon response in human neural cells, leading to their death, and is found in neurons of C9ORF72-ALS patients. Here, we report the spatial coincidence of cdsRNA and pTDP-43 inclusions in human postmortem tissue with Alzheimer's disease pathology, and upregulated interferon response genes in affected regions. CdsRNA also accumulates in a human TDP-43 G298S iPSC cortical neuronal model. We use cryptic exon detection as a proxy for TDP-43 mislocalization and demonstrate that FDA-approved JAK inhibitors baricitinib and ruxolitinib, which block interferon signaling, show protective effects only in brains with elevated cryptic exon expression. A CRISPR screen reveals TYK2 as a top hit, and TYK2 knockdown and the selective TYK2 inhibitor deucravacitinib rescue cdsRNA-induced toxicity. We find parallel neuroinflammatory mechanisms, dependent on TYK2 - a potential disease-modifying target - for TDP-43-associated Alzheimer's disease and C9ORF72-ALS.\n\nID: 41811178\nTitle: Cell type-specific network analysis in Diversity Outbred mice identifies genes potentially responsible for human bone mineral density GWAS associations.\nAbstract: Genome-wide association studies (GWASs) have identified many sources of genetic variation associated with bone mineral density (BMD), a clinical predictor of fracture risk and osteoporosis. Aside from the identification of causal genes, other difficult challenges to informing GWAS include characterizing the roles of predicted causal genes in disease and providing additional functional context, such as the cell-type predictions or biological pathways in which causal genes operate. Leveraging single-cell transcriptomics (scRNA-seq) can assist in informing BMD GWAS by linking disease-associated variants to genes and providing a cell-type context for which these causal genes drive disease. Here, we use large-scale scRNA-seq data from bone marrow-derived stromal cells cultured under osteogenic conditions (BMSC-OBs) from Diversity Outbred (DO) mice to generate cell type-specific networks and contextualize BMD GWAS-implicated genes. Using trajectories inferred from the scRNA-seq data that map cell state transitions, we identify networks enriched with genes that exhibit the most dynamic changes in expression across trajectories. We discover 21 network driver genes, which are likely to be causal for human BMD GWAS associations that colocalize with expression/splicing quantitative trait loci (eQTLs/sQTLs). These driver genes, including Fgfrl1 and Tpx2, along with their associated networks, are predicted to be novel regulators of BMD via their roles in the differentiation of mesenchymal lineage cells. In this work, we showcase the use of single-cell transcriptomics from mouse bone-relevant cells to inform human BMD GWAS and prioritize genetic targets with potential causal roles in the development of osteoporosis.\n\nID: 41752118\nTitle: Amyotrophic Lateral Sclerosis (ALS) Genetics and Microbiota: A Comprehensive Review.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a severe, progressive neurodegenerative disorder characterized by the loss of upper and lower motor neurons, affecting 0.5 to 2.6 per 100,000 people, with a median survival of 2 to 5 years. It is increasingly seen as a multisystem disorder, sharing essential clinicopathological features with Frontotemporal Dementia (FTD). This convergence arises from overlapping molecular processes, including severe oxidative stress, glutamate-mediated excitotoxicity, mitochondrial dysfunction, and widespread aggregated TDP-43 proteinopathy in both sporadic and familial cases. Several key genetic factors have been identified, particularly mutations in C9orf72, SOD1, TARDBP, and FUS, which serve as important targets for novel treatments, such as Tofersen, a recently approved SOD1-specific antisense oligonucleotide (ASO) gene therapy. Additionally, there is increasing evidence of the gut-brain connection. Dysbiosis, involving species such as Akkermansia muciniphila, and lower levels of neuroprotective metabolites, such as nicotinamide, may affect the course of the disease. As a result, treatment strategies are shifting toward a personalized approach. This includes using gene therapy, ranging from ASOs and RNA interference (RNAi) to new CRISPR-based genome editing. It also involves exploring microbiome-modulating treatments, such as specific probiotics and Fecal Microbiota Transplantation (FMT). While microbiome and gene therapies remain largely experimental, their potential is promising, as highlighted by the recent approval of Tofersen. These novel approaches could be further enhanced and guided by more robust diagnostic criteria and by investigating early multimodal treatment strategies to slow the progression of this complex disease.\n\nID: 41727111\nTitle: Cellular Aging Signatures in the Plasma Proteome Record Human Health and Disease.\nAbstract: Aging is asynchronous across cells and organs, but whether plasma proteins can capture cell type-specific aging and predict disease and mortality remains unknown. We developed machine learning models to estimate the biological age of more than 40 distinct cell types-spanning neuronal, immune, glial, endocrine, epithelial, and musculoskeletal origins-using over 7,000 plasma proteins measured in 60,000 individuals across three cohorts, comprising the largest human plasma proteomics aging study to date. Individuals showed heterogeneous aging profiles, with 20-25% exhibiting accelerated aging in a single cell type and 1-3% across ten or more cell types. APOE genotype showed antagonistic aging effects in different cell types: APOE4 carriers exhibited older astrocytes but younger macrophages, while APOE2 carriers showed the inverse. Cellular aging signatures were uniquely associated with disease status and predicted incident disease and mortality over 15 years of follow-up. Amyotrophic lateral sclerosis (ALS) showed the strongest association with skeletal myocyte aging (hazard ratio = 12.7 for extreme accelerated versus youthful aging). In Alzheimer's disease (AD), prevalent cases showed accelerated aging across multiple neural and peripheral cell types, with extreme astrocyte aging conferring AD risk comparable to APOE4 carrier status. Moreover, extreme astrocyte aging increased AD risk in APOE4/4 carriers threefold, while youthful astrocytes strikingly reduced risk. Beyond neurodegeneration, respiratory cell aging identified smokers at 58% higher lung cancer risk, and myeloid aging identified normoglycemic individuals at higher diabetes risk. Both specific cellular vulnerabilities and cumulative aging burden influenced survival, wherein youthful immune or neuronal profiles were protective. A polycellular aging risk score provided robust mortality risk stratification across platforms and cohorts. These findings establish a framework for quantifying biological aging at the cellular resolution using plasma proteomics, revealing heterogeneity in aging trajectories and their impact on disease susceptibility and resilience.\n\nID: 41721094\nTitle: Gene therapy for huntington's disease: advances, challenges, and future perspectives.\nAbstract: An abnormal amplification of the CAG trinucleotide repeat in the huntingtin (HTT) gene causes Huntington\u2019s disease (HD), a devastating neurological illness. The striatum and cortex are primarily affected by the gradual neuronal dysfunction and loss caused by the mutant huntingtin (mHTT) protein. Although there have been notable improvements in symptomatic management, curative treatments remain unavailable. A promising treatment option that offers specifically designed interventions to decrease or eradicate mutant HTT expression is gene therapy. RNA-targeted treatments (antisense oligonucleotides, RNA interference), DNA editing methods (Clustered Regularly Interspaced Short Palindromic Repeats/caspase 9, zinc finger nucleases, Transcription Activator-like Effector Nuclease), and advanced delivery systems (viral and non-viral vectors, lipid nanoparticles, exosomes) are just a few of the many approaches that are presently being researched. AMT-130 and tominersen clinical trials provide crucial information about the viability, security, and effectiveness of gene therapy for HD. It is hoped that developments in genome editing and delivery methods would make gene therapy a viable treatment for HD. However, challenges remain, including immunological responses, blood-brain barrier penetration, and off-target consequences. This review delves into the latest developments in HD gene therapy, highlighting new approaches, obstacles, and potential future paths to a permanent cure.\n\nID: 41720774\nTitle: A neurotoxic cryptic peptide arising from TDP-43-dependent cryptic splicing of PKN1.\nAbstract: Dysfunction of transactive response DNA-binding protein 43 (TDP-43) drives neurodegeneration in amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD), in part through inducing aberrant RNA splicing. However, whether such mis-splicing yields stable, pathogenic proteins remains unclear. Here, we identify a TDP-43-repressed cryptic exon in Protein kinase N1 (PKN1), designated PKN1-5a1, which is activated in ALS patient brains and introduces a premature termination codon. This aberrant transcript escapes nonsense-mediated decay and is translated into a truncated peptide, PKN1-N207 (PKN207), detectable in AD brains with TDP-43 pathology. In mice, PKN207 impairs cognition, memory, and synaptic plasticity. Our findings demonstrate that TDP-43 loss-induced cryptic splicing can generate stable neurotoxic polypeptides, revealing a peptide-mediated mechanism in TDP-43 proteinopathies.\n\nID: 41685312\nTitle: Multi-omics characterization of RNA modification enzymes identifies NAT10 as a functionally validated prognostic biomarker in hepatocellular carcinoma.\nAbstract: RNA modification enzymes (RMEs) are key post-transcriptional regulators that impact RNA stability, translation, and splicing. Dysregulation of RMEs is closely associated with tumor initiation and progression. However, their global regulatory patterns and clinical relevance across cancer types remain incompletely characterized. We conducted an integrative multi-omics analysis of RME expression, copy number variation (CNV), and clinical outcomes across multiple cancers. Machine learning algorithms were employed to identify tumor-discriminating RME signatures. Single-cell RNA sequencing (scRNA-seq) characterized tumor microenvironmental heterogeneity. A LASSO-derived prognostic model was established and validated in independent cohorts. Drug sensitivity prediction and supportive functional assays (EdU assays, qRT-PCR, immunohistochemistry) were performed for representative RMEs. RMEs were broadly upregulated across cancers and showed strong associations with CNV gains. Machine learning identified 12 RMEs that reliably discriminated tumor from normal tissues. Single-cell transcriptomic analysis showed that 10 of the 12 selected RMEs (DKC1, METTL1, NAT10, TRMT1, RPUSD1, PUS1, WDR4, TRMU, ADAT2, GTPBP3) exhibited higher expression in tumor-infiltrating cells compared with adjacent normal tissues. T-cell subpopulations displayed marked heterogeneity, with ADAT2 preferentially enriched in regulatory T cells. CellChat analysis revealed T cell subsets as key mediators of intercellular communication via multiple immune-related pathways. A 6-gene prognostic model exhibited independent prognostic power and was integrated into a well-calibrated nomogram. Drug-response prediction revealed that high-risk patients exhibited enhanced sensitivity to microtubule-targeting agents and kinase inhibitors, whereas low-risk patients showed preferential response to epigenetic modulators. Importantly, supportive functional assays showed that NAT10 knockdown, validated by qRT-PCR, was associated with reduced proliferative activity in HCC cells as evidenced by EdU assays, and IHC validation further corroborated its overexpression in clinical tumor specimens compared to adjacent normal tissues. This study delineates a CNV-associated landscape of RME dysregulation across cancers and establishes a 12-RME diagnostic signature and a 6-gene prognostic model with robust predictive performance. Single-cell analyses reveal tumor- and cell-type-specific expression patterns of RMEs, while supportive functional data suggest a potential biological relevance of NAT10 in HCC. Collectively, these findings provide an association-based framework for understanding the potential roles of RNA modification programs in cancer progression and clinical stratification.\n\nID: 41674784\nTitle: CRISPR-Cas technologies in neurodegenerative disorders: mechanistic insights, therapeutic potential, and translational challenges.\nAbstract: CRISPR-Cas genome-editing technologies have emerged as powerful tools for precise DNA and RNA modulation, offering promising therapeutic strategies for neurodegenerative disorders such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS). This review critically evaluates current CRISPR/Cas applications in neurodegeneration, with emphasis on mechanistic insights, therapeutic outcomes, and translational feasibility. Preclinical and early translational studies demonstrate that CRISPR-Cas platforms can correct pathogenic mutations, suppress toxic gene expression, and restore neuronal function. Advanced modalities, including base and prime editing, CRISPRi/a, and RNA-targeting Cas systems, improve precision and reduce genomic damage, which is particularly advantageous in post-mitotic neurons. Emerging CRISPR-based diagnostics (e.g., SHERLOCK and DETECTR), AI-assisted sgRNA design, and machine-learning approaches for predicting off-target effects further enhance the safety, stratification, and monitoring of CRISPR therapeutics. In parallel, patient-derived brain organoids and assembloids provide scalable human-relevant platforms for mechanistic studies and preclinical validation. Despite this progress, major challenges remain, including efficient delivery across the blood-brain barrier, immune responses, long-term safety, and ethical and regulatory considerations. Overall, CRISPR-Cas technologies hold strong potential as disease-modifying interventions for neurodegenerative disorders, provided that advances in delivery systems, artificial intelligence integration, and regulatory oversight continue to evolve toward clinical translation.\n\nID: 41665764\nTitle: Machine learning, whole-transcriptome and integrative omics analysis reveals key regulatory networks governing human spermatogonial stem cells.\nAbstract: Spermatogenesis\u2014the process of sperm cell development\u2014is highly dependent on precise and dynamic regulation of gene expression, much of which is controlled by Regulatory networks and hub genes governing spermatogonial stem cells (SSC) identity, including components involved in post-transcriptional regulations. During this complex process, a wide range of RNA-binding proteins (RBPs) and RNA processing enzymes coordinate the transcription, splicing, transport, storage, and translation of mRNAs required for germ cell development. Raw sequencing data were processed and normalized using standard bioinformatics pipelines (e.g., STAR, DESeq2). To identify key Regulatory networks and hub genes governing SSC identity, including components involved in post-transcriptional regulations, we applied integrative omics approaches by combining transcriptomic data with publicly available proteomic and interactome databases. Hub proteins were determined through weighted gene co-expression network analysis (WGCNA) and centrality scoring in protein-protein interaction (PPI) networks. Machine learning models, including random forest and support vector machine (SVM), were trained to classify critical regulators based on expression features and metadata. Additionally, cell-cell communication was inferred using ligand-receptor interaction analysis via CellChat and NicheNet to explore the microenvironmental impact on RNA metabolic processes. All findings were validated across culture conditions and biological replicates to ensure robustness. Microarray analysis revealed 92 upregulated and 126 downregulated genes in SSCs versus htFib, with enrichment in motile cilium assembly, spermatid development, and gamete generation. DEGs were mainly extracellular matrix proteins, transporters, and adhesion molecules. PPI network and KEGG analyses identified key hub genes (e.g., MMP3, CAV1, TGFBR2) involved in cell cycle and meiosis pathways. Single-cell RNA-seq of human testicular cells identified 17 clusters, including germ and somatic cell types. Germ cell re-clustering defined SSC subpopulations marked by genes such as FAM74F1, SMCP, and ADAD1. GSEA indicated metabolic shifts, especially in oxidative phosphorylation, during SSC differentiation. Ligand\u2013receptor analysis revealed active cell-cell signaling, particularly involving fibroblasts and macrophages. These findings enhance the understanding of human spermatogonia culture and gene expression, providing insights into SSC biology and potential applications in reproductive medicine.\n\nID: 41649621\nTitle: CRISPR-Based Therapy for Ischemic Stroke: A Narrative Review.\nAbstract: Ischemic stroke (IS) is one of the most common neurological diseases worldwide and is caused by the blockage of cerebral blood vessels, leading to reduced blood flow and neuronal damage. Given the limitations of existing treatments, CRISPR gene-editing technology has emerged as a promising strategy to precisely target the molecular pathways underlying IS pathophysiology. By enabling intervention in genes regulating inflammation, apoptosis, and repair, CRISPR enables more precise and effective therapies. Various CRISPR delivery systems, including viral vectors, nanocarriers, and extracellular vesicles, play crucial roles in the effective access of this tool to neural cells. Studies have shown that the use of CRISPR-Cas9 to modulate key pathogenic pathways, including those governing inflammation, oxidative stress, and cell death, can prevent neuronal damage and improve neurological function. Additionally, targeting ncRNAs and RNA methylation with CRISPR-based systems plays a role in regulating oxidative stress and stress granule formation. The use of CRISPR to modulate cell communication and organelle transfer and correct mitochondrial mutations has also been considered a neuroprotective mechanism. Despite persistent challenges in targeted and safe delivery, substantial preclinical advances, primarily in rodent models, underscore the potential for CRISPR-based therapies to transform future stroke treatment. These findings suggest that CRISPR-based strategies could evolve into precision neurotherapeutics that address root molecular pathologies, potentially complementing or surpassing current stroke interventions.\n\nID: 41643021\nTitle: Blocking RAN translation without altering repeat RNAs rescues C9ORF72-related ALS and FTD phenotypes.\nAbstract: GGGGCC (G4C2) repeat expansion in C9ORF72 is the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Toxicity is thought to result from the accumulation of either repeat RNAs and/or dipeptide repeat proteins (DPRs) translated from repeat-containing transcripts through repeat-associated non-AUG (RAN) translation. To disentangle RNA from DPR toxicity, we mutated a CUG codon predominantly used to initiate DPR translation from all three reading frames. This mutation disrupted DPR synthesis while preserving the expression of repeat-containing RNAs. Despite the accumulation of RNA foci, behavioral deficits and pathological abnormalities, including p-TDP-43 inclusions, STING activation, motor neuron loss, neuroinflammation, and increased plasma neurofilament concentration, were alleviated in C9ORF72 mice. Base editing of the CUG codon also improved molecular phenotypes and survival in patient induced pluripotent stem cell-derived neurons, which highlights the potential of therapeutically targeting DPR production rather than repeat RNAs.\n\nID: 41577209\nTitle: Emerging multi-omics biomarkers in glioblastoma: Integrative insights from genomics to metabolomics.\nAbstract: Glioblastoma (GBM) is the most malignant form of primary brain tumor in adults, described by profound molecular heterogeneity, rapid progression, and limited therapeutic response. Despite advances in chemotherapy (TMZ), radiotherapy, and surgery, patient outcomes remain poor, with a median survival of 12-15\u00a0months. Traditional single-omics studies have identified critical biomarkers such as IDH mutations, MGMT promoter methylation, and EGFR alterations; however, these provide only partial insight into the disease's complexity. Recent integrative multi-omics approaches encompassing genomics, transcriptomics, epigenomics, proteomics, metabolomics, and non-coding RNAs have transformed the landscape of biomarker discovery in GBM. Genomic profiling has revealed recurrent mutations and subtype-specific aberrations, while transcriptomic analyses refine molecular classification and uncover alternative splicing and fusion events. Epigenomic markers, particularly MGMT methylation and G-CIMP status, are now central to prognosis and therapy stratification. Proteomic and metabolomic studies highlight dysregulated pathways, metabolic vulnerabilities, and non-invasive biomarkers in cerebrospinal fluid and plasma. Integrating multi-omics data not only improves diagnostic and prognostic accuracy but also unveils therapeutic targets, offering opportunities for precision oncology. Furthermore, liquid biopsy and single-cell/spatial omics enhance real-time monitoring of disease progression and treatment response, addressing challenges posed by intratumoral heterogeneity. This review synthesizes recent advances in GBM biomarker research across multiple omics layers, emphasizing their complementary roles in unravelling tumor biology, guiding personalized treatment, and shaping future therapeutic strategies.\n\nID: 41573891\nTitle: Dual-targeting snRNA gene therapy rescues STMN2 and UNC13A splicing in TDP-43 proteinopathies.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder caused by the selective deterioration of motor neurons in the central nervous system (CNS). A key driver of this pathogenesis is nuclear loss of ALS-associated protein TDP-43, leading to mis-splicing of TDP-43 targets including important neuronal genes STMN2 and UNC13A . Here, we have developed a gene therapy strategy for ALS and related TDP-43 proteinopathies, to correct mis-splicing of both STMN2 and UNC13A cryptic exons using small nuclear RNAs (snRNAs) encoded from a single vector. We identified promoter sequence elements to increase therapeutic snRNA expression by 10-fold, then further optimized the expression cassette with combinatorial snRNA targeting to rescue multiple cryptic splicing targets. The engineered snRNAs restored normal pre-mRNA processing of both STMN2 and UNC13A transcripts despite TDP-43 loss of function, rescuing stathmin-2 protein levels in iPSC derived motor neurons, restoring their axonal regeneration capacity to wild-type levels. In addition, adeno-associated virus (AAV) delivery of the snRNAs to the murine central nervous system in the constitutive cryptic splicing model Stmn2 Hum\u0394GU fully restored cortical Stmn2 pre-mRNA processing, highlighting the utility of snRNAs as a therapeutic modality in vivo . Together, this study demonstrates that snRNAs are a promising and versatile therapeutic strategy for the simultaneous correction of multiple aberrant transcripts affected by cryptic splicing in TDP-43 proteinopathies.\n\nID: 42385702\nTitle: Recurrent patterns of TOP1-mediated neuronal genomic damage shared by major neurodegenerative disorders.\nAbstract: Amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD) represent two major categories of neurodegenerative disorders-TAR DNA-binding protein 43 (TDP-43) and tau proteinopathies-for which the mechanisms driving neuronal death remain unclear. Single-cell whole-genome sequencing of 469 neurons from C9ORF72 ALS, C9ORF72 FTD, AD, and control brains revealed increased somatic single-nucleotide variants (sSNVs) and insertions/deletions (sIndels) in all three diseases. Mutational signature analysis identified a disease-associated sSNV signature consistent with oxidative damage and an sIndel process affecting 22% of ALS, 76% of FTD, and 61% of AD neurons-but only 2% of control neurons-resembling signature ID4, previously linked to topoisomerase 1 (TOP1)-mediated mutagenesis. Rapid approach to DNA adduct recovery (RADAR) assays confirmed increased TOP1-DNA covalent complexes, and duplex sequencing confirmed the increased sIndels and identified single-strand events as likely precursor lesions. TOP1-associated sIndel mutagenesis and genome instability thus represent a mechanism shared by both TDP-43 and tau neurodegeneration.\n\nID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.\n\nID: 42317262\nTitle: Spatial transcriptomics in Alzheimer's disease: technologies, challenges and discoveries.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder that is associated with cognitive decline in the elderly. While \u03b2-amyloid (A\u03b2) plaques and neurofibrillary tau tangles have been used to define and stage AD onset in human brain, how these pathologies can affect various cell types nearby remains a subject of intense interest in the field. Recent developments in spatial transcriptomic technology have seen accelerated growth, and spatial transcriptomic platforms have been used independently or together with single cell transcriptomic methods to characterize cellular changes in the AD brain from mouse models and human. Here, we review current-era spatial transcriptomic technologies, analytical pipelines and their implementation in AD research. We summarize findings from spatial transcriptomics in AD, and discuss limitations and challenges associated with various spatial transcriptomic platforms. The pathological hallmarks for AD were described by Alois Alzheimer over a century ago; from the convergence of a century of AD research and technological advances in imaging and transcriptomics, a new era in AD has emerged. Although current-era spatial platforms feature limitations and challenges, evolution of spatial transcriptomics and its combined implementation with other data modalities promises significant strides in AD and related neurodegenerative disorders.\n\nID: 42274555\nTitle: Polypharmacology of Pathway Crosstalk in Neurodegenerative Diseases: Chemical Modulation of Interconnected Signaling Networks.\nAbstract: Neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS), arise from highly interconnected molecular and cellular abnormalities that progressively lead to neuronal dysfunction, synaptic failure, and cell death. This review provides a unified framework to understand the interrelated molecular mechanisms driving these diseases, with a focus on identifying key disease-specific intervention nodes. Core contributors include oxidative stress, mitochondrial dysfunction, protein aggregation, neuroinflammation, and emerging roles of peroxisomal dysfunction in redox imbalance, lipid dysregulation, and inflammatory amplification. Single-target therapies often show limited efficacy due to the complex, interconnected nature of these pathways. In contrast, polypharmacology, which targets multiple disease-relevant mechanisms simultaneously, offers a more promising therapeutic strategy. This review critically examines how pathway crosstalk drives neurodegenerative progression, with particular emphasis on mitochondrial-ROS-inflammatory signaling, aggregation-proteostasis failure, synaptic-neuroimmune dysfunction, and gut-brain communication. It evaluates various multi-node intervention strategies, including multi-target-directed ligands (MTDLs), molecular hybrids, natural products, drug repurposing, and nanocarrier-based delivery systems. Advances in network pharmacology, artificial intelligence (AI), bioinformatics, and multi-omics have enhanced the identification of actionable therapeutic nodes, candidate compounds, and brain-targeted delivery platforms. Notably, the NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome and cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathways-play distinct roles in neuroinflammation, amplifying neuronal damage by releasing inflammatory cytokines and inducing mitochondrial dysfunction. However, successful translation into clinical practice remains constrained by challenges such as blood-brain barrier penetration, patient heterogeneity, and biomarker limitations. The review advocates for a shift towards mechanism-informed, patient-stratified polypharmacological strategies to better address the network pathology of neurodegeneration, despite significant translational hurdles.\n\nID: 42259773\nTitle: Engineering an AIEgen-based platform integrating CRISPR/Cas9 to remodel the tumor microenvironment and reinforce photo-immunotherapy against glioblastom.\nAbstract: Glioblastoma remains one of the most lethal brain tumors. Although immunotherapy and other therapeutic modalities has achieved significant therapeutic success in several malignancies, its efficacy in glioblastoma remains limited primarily due to the complex tumor microenvironment (TME) and physiological barriers such as the blood-brain barrier (BBB). In this context, nanomedicine and gene editing have emerged as promising strategies due to their unique ability to cross the BBB and protect therapeutic agents through intrinsic physicochemical properties. To overcome the physiological barriers for better therapeutic outcomes. Here, a novel aggregation-induced emission luminogen (AIEgen), NDA-DPE, was synthesized, exhibiting NIR-I to NIR-II fluorescence and dual photothermal (PTT) and photodynamic (PDT) properties through restricted intramolecular motion. Bone-derived neutrophil-based biomimetic nanoparticles (bNe@AIE/Cas9-CD73) were then prepared by integrating NDA-DPE with CRISPR/Cas9-mediated CD73 gene silencing. The neutrophil encapsulation enabled efficient BBB penetration and targeted accumulation in glioblastoma tissue. CRISPR/Cas9-CD73 downregulated CD73 expression, disrupted the ATP-adenosine axis, and reshped the immunosuppressive TME into an immuno-supportive one, increasing the therapeutic sensitivity of tumor cells. Under NIR-II excitation, bNe@AIE/Cas9-CD73 achieved fluorescence-guided PTT and PDT, inducing immunogenic cell death (ICD), stimulating immune-cell recruitment, and activating systemic antitumor immunity. bNe@AIE/Cas9-CD73 demonstrated a potent gene-photothermal-photodynamic-immune synergistic effect, significantly inhibiting glioblastoma growth and establishing a promising nanoplatform for effective and targeted glioblastoma treatment.\n\nID: 42171861\nTitle: TDP-43 Acetylation at the Neuroimmune Interface: A Hypothesis-Driven Framework for Peripheral Inflammatory Stratotypes in ALS.\nAbstract: Transactive Response Deoxyribonucleic Acid-Binding Protein-43 (TDP-43) acetylation may couple motor-neuron degeneration to systemic immune orchestration in Amyotrophic Lateral Sclerosis (ALS). Upon nuclear clearance and mislocalisation, TDP-43 enters the periphery; acetylation shapes its conformation, trafficking and immunogenicity. This narrative review synthesises single-cell transcriptomics, proteomic immunoprofiling and clinical inflammatory phenotyping to examine whether site-specific acetylated TDP-43 species may be associated with peripheral inflammatory signatures relevant to ALS immunopathology. By integrating separate datasets on acetylated TDP-43, monocyte phenotypes and cytokine modules, we propose two provisional endotypes characterised by monocyte reprogramming, cytokine modules and Blood-Brain Barrier (BBB) dysfunction-each representing clinically actionable pathways. Framed as a provisional neuroimmune interface, the acetylation state is considered here as a plausible molecular correlate and potential therapeutic entry point: a measurable clue to inform pharmacological targeting and, potentially, a modifiable target via p300CREB-Binding Protein (CBP)-Histone Deacetylase (HDAC) axes or sirtuin activity. Recasting TDP-43 from neuropathological hallmark to immunoactive sentinel supports a shift from descriptive nosology to stratified immunotherapy, in which treatment allocation is informed by acetylation-defined peripheral signatures.\n\nID: 42171198\nTitle: Targeting lipid nanoparticle mediated co-delivery of edaravone and kaempferol for amyotrophic lateral sclerosis therapy.\nAbstract: Amyotrophic lateral sclerosis (ALS) is characterized by a progressive and selective loss of motor neurons in the central nervous system, particularly in the brain and spinal cord. However, the main cellular mechanisms and cell death pathways leading to motor neuron degeneration have not yet been clarified. Research indicates evidence of ferroptosis in ALS, and the natural compound kaempferol has been demonstrated to inhibit neuronal ferroptosis. However, damage to the blood-brain barrier (BBB) prevents the drug from penetrating the central nervous system, which significantly reduces its therapeutic efficacy. Here, we developed a targeted delivery system named Eda/Kae@Lip-RGD (EKLR), which consisted of liposome-grafted RGD peptides for the co-delivery of the drugs kaempferol and edaravone, capable of crossing the BBB to provide co-delivery of kaempferol and edaravone for combined treatment of ALS. As expected, treatment with EKLR for one month significantly slowed down weight loss and improved athletic performance in SOD1G93A transgenic mice. Mechanistically, this nanomedicine suppressed ferroptosis by upregulating the antioxidant proteins GPX4 and SLC7A11, alongside the downregulation of Nrf2 and ACSL4 levels, thus collectively preserving neuronal integrity. Meanwhile, EKLR restored the normal morphology and the survival rate of neurons and maintained the mitochondrial structure and morphological integrity. Accordingly, this nanoplatform may represent a distinctive and potentially effective strategy for achieving neuroprotection in ALS as well as in other disorders of the central nervous system.\n\nID: 42141372\nTitle: Metabolomics at the Crossroads of Forensic Toxicology and Precision Diagnostics: Analytical Innovations and Translational Opportunities.\nAbstract: Metabolomics is the comprehensive analysis of small-molecule metabolites in living systems and is increasingly being applied in forensic science and health diagnostics. This review broadly integrates the foundational principles of metabolomics, key analytical techniques, and translational applications across forensic toxicology, postmortem interval estimation, and disease biomarker discovery. Advanced methodologies, such as mass spectrometry, nuclear magnetic resonance spectroscopy, and single-cell metabolomics, have knowingly enhanced sensitivity and resolution, enabling accurate detection of drug-related biomarkers, metabolic perturbations, and trauma-induced molecular signatures. Moreover, integrating metabolomics with cellular and molecular biology offers novel insights into disease pathophysiology, particularly in cancer, neurodegeneration, and metabolic disorders. Hence, emphasis is placed on the role of metabolite-mediated signaling and epigenetic regulation in bridging diagnostic gaps. The review delves deeper into recent advances in DNA-based phenotypic prediction, trace-based evidence collection strategies, and artificial-intelligence-driven analytical models. The conceptual and regulatory fundamentals of forensic and clinical metabolomics are compared in this review, exposing potential trends for transdisciplinary innovation.\n\nID: 42136293\nTitle: Targeted Nanotechnology Approaches to Bypass the Blood-brain Barrier in Neurodegenerative Disorders.\nAbstract: Neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), and Huntington's disease (HD) are a growing health burden across the world because of the progressive loss of brain cells and the ineffective nature of the available treatment. One significant challenge in the treatment of these conditions is the Blood- -Brain Barrier (BBB), a highly selective interface that limits the access of most therapeutic molecules to the central nervous system. Nanotechnology has become an attractive approach to addressing this difficulty, as it enables the delivery of drugs with high accuracy and actively engages in the repair of the BBB. This review provides an overall synthesis of focused nanotechnology solutions aimed at both circumventing and restoring BBB function in neurodegenerative illnesses. It discusses various nanoparticle (NP) platforms such as polymeric, lipid-based, micellar, metallic, and carbon-derived systems in the light of their physicochemical aspects, transport across the BBB, and therapeutic efficacy. Particular emphasis is put on the receptor-mediated transcytosis, neurovascular unit modulations, and the regulation of Wnt, Shh, and Tie-2 signalling pathways, which are BBB integrity pathways. The review incorporates mechanisms of BBB repair in combination with neuroprotective nanotherapies, rather than focusing solely on end repair. This review covers the role of targeted nanotechnology in the future of therapeutic approaches for neurodegenerative diseases. By connecting materials science, molecular neuroscience, and clinical innovation, it demonstrates how next-generation brain-targeted therapies can be developed using targeted nanotechnology.\n\nID: 42135512\nTitle: Integrated single-cell and spatial transcriptomic profiling in ALS uncovers peripheral-to-central immune infiltration and reprogramming.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder marked by progressive motor neuron (MN) degeneration in the brain and spinal cord. Although neuroinflammation is increasingly recognized as a hallmark of ALS, the precise molecular programs linking immune responses to MN pathology remain poorly defined. Using an integrated approach that combines single-cell and bulk RNA sequencing with spatial proteogenomics, we characterized both shared and distinct immune dynamics in peripheral blood and spinal cord tissues from patients with sporadic ALS and those carrying C9orf72 repeat expansions. Our analysis revealed broad immune remodeling in C9orf72 ALS, ALS subtype-specific and progression-associated differences in monocyte activation and antigen-experienced CD8 effector memory T cells with clonal features consistent with antigen-driven responses. Spatial mapping revealed complement activation and lipid-programmed myeloid states converging at sites of MN loss and TDP-43 pathology. Together, these findings connect peripheral and central immune alterations to ALS heterogeneity and highlight stratified immunomodulation as a potential therapeutic strategy.\n\nID: 42123994\nTitle: Long-Chain Fatty Acids as Drivers of Neuroinflammation in Neurodegeneration: Mechanistic Links to Lipid Peroxidation, Ferroptosis, and Mitochondrial Dysfunction.\nAbstract: Background: Neurodegenerative diseases (NDs) are mainly considered disorders marked by severe immunometabolic imbalance, characterized by ongoing neuroinflammation and glial activation. While mitochondrial dysfunction and oxidative stress are well-known features, the upstream metabolic factors linking these pathological processes remain poorly understood. Methods: In this review, we examined recent preclinical and clinical studies exploring the connections between lipid metabolism, glial immunometabolism, and regulated cell death pathways. Our focus was on how long-chain fatty acids (LCFAs) facilitate communication among mitochondria, reactive oxygen species (ROS), and ferroptosis in Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS). Results: New evidence shifts LCFAs from merely being passive indicators of cellular damage to active, upstream regulators of the neuroimmune response. Existing research shows that excess LCFA intake can overload astrocytic mitochondrial oxidative phosphorylation, leading to abnormal lipid droplet buildup and reactive astrogliosis. This lipid-driven reactivity promotes microglial polarization toward a persistent pro-inflammatory state. Notably, high levels of specific LCFAs, especially arachidonic acid, increase ROS production and lipid peroxidation. This lipotoxic environment ultimately triggers ferroptosis, an iron-dependent form of cell death shared across multiple NDs. Conclusions: The harmful interaction among mitochondrial dysfunction, lipid peroxidation, and ferroptosis is driven by an imbalance in LCFA levels. Addressing current challenges, such as the complex effects of polyunsaturated fatty acid supplementation, requires advanced techniques like single-cell multi-omics and artificial intelligence. Understanding this intricate lipidomic-transcriptomic crosstalk is crucial for moving toward personalized neuroimmunometabolism and developing new treatments to prevent ferroptosis.\n\nID: 42070160\nTitle: miRNAs in Amyotrophic Lateral Sclerosis: Tiny Molecules, Tremendous Impact.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder distinguished by progressive motor neuron degeneration, with diverse clinical manifestations and complex genetic and environmental triggers. The variability in disease progression underscores the necessity for tailored diagnostic and therapeutic approaches. MicroRNAs (miRNAs), small non-coding RNAs that regulate gene expression, have emerged as promising biomarkers and therapeutic targets in ALS. Dysregulation of specific miRNAs has been linked to mechanisms of ALS, including neuromuscular dysfunction, neuroinflammation, and neuronal survival/apoptosis. The potential of miRNA-based therapies, such as mimics and inhibitors, offers a more integrated approach by modulating entire disease networks, rather than targeting isolated pathways. However, challenges persist, particularly in delivering these therapies efficiently across the blood-brain barrier and minimizing off-target effects. Current delivery strategies involving nanoparticles, viral vectors, and exosome-based approaches require optimization for clinical use. This review synthesizes the latest research on miRNA-mediated mechanisms in ALS, evaluating their diagnostic, prognostic, and therapeutic potential, while highlighting the current limitations in clinical validation. It underscores the importance of standardized methodologies, multi-omics integration, and rigorous validation to facilitate the clinical translation of miRNA-based strategies. Standardized protocols and multicenter validation in large cohorts are essential to confirm the diagnostic accuracy of miRNAs, paving the way for their clinical application in ALS precision medicine.\n\nID: 42063624\nTitle: Amyloid beta pathology induces astrocytic pTDP-43 mislocalization and disrupts TDP-43-regulated cryptic exon transcripts.\nAbstract: While amyloid-\u03b2 (A\u03b2) and tau are hallmark pathologies of Alzheimer's disease (AD), TDP-43 proteinopathy is increasingly recognized as an important contributor, occurring in up to 57% of AD cases and associated with accelerated cognitive decline. TDP-43 regulates RNA splicing, and its mislocalization leads to cryptic exon inclusion and loss of canonical protein function. While neuronal TDP-43 pathology has been well studied, its role in astrocytes remains less understood. Recent findings suggest increased phosphorylated TDP-43 (pTDP-43) inclusions in astrocytic endfeet in AD and a bidirectional interaction between A\u03b2 and TDP-43, promoting mutual aggregation. We analyzed pTDP-43 immunoreactivity (IR) in astrocytic perivascular end-feet, nuclei, and cytosol in hippocampal sections from 3-month-old and 18-month-old AppNL-F/NL-F mice and 18-month-old wild-type controls using ImageJ. In vitro, primary fetal human astrocytes were exposed to oligomeric A\u03b242, and changes in cytosolic and nuclear pTDP-43 IR were quantified via ImageJ, while TDP-43 and pTDP-43 protein levels were measured using an in-house ELISA. Expression of canonical transcripts ATG4B and KALRN, involved in autophagy and synaptic support, was assessed by qPCR. Corresponding protein-level changes were evaluated using in-house ELISA. Our findings demonstrate significantly higher pTDP-43 accumulations in astrocytic nuclei, cytosol, and endfeet in 18-month-old AppNL-F/NL-F mice compared to age-matched wild-type mice. Astrocytes exposed to oligomeric A\u03b242 showed elevated cytosolic pTDP-43 IR and total pTDP-43 protein levels. Concurrently, expression of canonical ATG4B and KALRN transcripts was significantly reduced, which was accompanied by corresponding decreases in protein levels. Our findings demonstrate that pTDP-43 accumulates in astrocytic nuclei, cytosol, and endfeet in the presence of AD pathology. The observed A\u03b2-induced increase in cytosolic pTDP-43 and transcript disruption suggests a mechanistic link contributing to autophagy impairment and cytoskeletal changes in astrocytes, potentially exacerbating AD progression.\n\nID: 41977439\nTitle: Targeting Non-Coding RNAs as a Potential Therapeutic and Delivery Strategy Against Neurodegenerative Diseases.\nAbstract: Neurodegenerative diseases (NDs), including Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis (ALS), represent a growing global health challenge characterized by progressive neuronal loss and a lack of definitive disease-modifying treatments. This review explores the emerging potential of targeting non-coding RNAs (ncRNAs), such as microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and exosomal RNAs, to modulate pathogenic molecular pathways and address the underlying molecular origins of neurodegeneration. We evaluate the integration of advanced computational techniques for RNA structure prediction and gene regulatory network analysis, alongside chemical engineering strategies-such as Locked Nucleic Acids (LNAs) and phosphorothioate modifications-aimed at enhancing the stability and specificity of RNA-based molecules. Furthermore, we analyze cutting-edge delivery and editing technologies, including nanotechnology-driven solutions for precise neuronal targeting and the CRISPR/Cas13 system for direct ncRNA manipulation.The findings indicate that while challenges in delivery efficiency and long-term efficacy persist, the synergy of chemical engineering and computational modeling significantly improves the therapeutic profile of ncRNAs, with exosomal pathways offering a novel route for intercellular signaling modulation and biomarker discovery. Therapeutic interventions directed at specific clinical targets, such as miR-34a and BACE1-AS, demonstrate the capacity to influence protein aggregation and neuroinflammatory cascades. Although ncRNA-based therapies are currently in nascent stages, ongoing technological advancements in RNA editing and nanotechnology offer a transformative framework that could redefine the future of ND treatment and successfully halt disease progression rather than merely managing symptoms.\n\nID: 41945799\nTitle: Benzimidazole as a Versatile Scaffold for Developing Neurotherapeutics Against Neurodegenerative Diseases.\nAbstract: Neurodegenerative diseases (NDs) such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS) are characterized by progressive neuronal loss, leading to severe cognitive and motor dysfunction. Benzimidazole, a privileged heterocyclic scaffold, has emerged as a promising pharmacophore in modulating key pathological targets across these disorders. In AD, benzimidazole derivatives inhibit cholinesterases, glycogen synthase kinase-3\u03b2 (GSK-3\u03b2), and glutaminyl cyclase (QC), thereby addressing cholinergic dysfunction, tau phosphorylation, and amyloid aggregation. In PD and HD, they act as monoamine oxidase-B (MAO-B) inhibitors, dopamine D1/D2 receptor modulators, and N-methyl D-aspartate receptor antagonists, improving dopaminergic signalling and reducing excitotoxicity. In ALS, benzimidazoles regulate acetylcholine dysfunction and inhibit receptor-interacting protein kinase 1 (RIPK1), limiting neuroinflammation and cell death. Preclinical studies demonstrate potent enzyme inhibition, often with IC50 values in the nanomolar to micromolar range, alongside favourable ADMET properties enabling blood-brain barrier penetration. Clinically, the glutaminyl cyclase inhibitor Varoglutamstat has advanced to Phase II trials for AD, while Riluzole remains the only food and drug administration (FDA)-approved benzimidazole drug for ALS. The structural versatility of benzimidazoles supports their development as multi-target-directed ligands, addressing overlapping mechanisms such as protein aggregation, oxidative stress, and neuroinflammation. Emerging strategies including hybrid molecules, nanocarrier delivery, and AI-driven design may accelerate their clinical translation.\n\nID: 41931258\nTitle: CRISPR-Cas9 and next-generation gene editing strategies for therapeutic intervention of neurodegenerative pathways in Alzheimer's disease: a state-of-the-art review.\nAbstract: Alzheimer's disease (AD) is a progressive and multifactorial neurodegenerative disorder and the leading cause of dementia worldwide, characterized by extracellular amyloid-\u03b2 (A\u03b2) plaque deposition, intracellular neurofibrillary tangles composed of hyperphosphorylated tau, synaptic loss, mitochondrial dysfunction, oxidative stress, and chronic neuroinflammation. Despite major advances in understanding its molecular basis, currently approved therapies remain largely symptomatic and fail to halt or reverse neurodegeneration, emphasizing the urgent need for disease-modifying strategies. In this comprehensive state-of-the-art review, we examine the rapidly evolving landscape of CRISPR-Cas9 and next-generation gene-editing technologies, including base editors and prime editors, as innovative therapeutic platforms for precisely modulating AD-associated genetic and molecular pathways. We discuss targeting of critical genes such as APOE4, APP, PSEN1, PSEN2, and MAPT, which play central roles in amyloid processing, tau pathology, lipid metabolism, and neuroinflammatory cascades, and evaluate strategies for allele-specific correction, gene silencing, and transcriptional regulation using CRISPR interference/activation and epigenome editing tools. The review further explores multiplex editing approaches that simultaneously target interconnected pathogenic networks underlying A\u03b2 accumulation, tau hyperphosphorylation, microglial activation, and synaptic dysfunction. A central focus is placed on overcoming delivery barriers to the central nervous system, particularly the blood-brain barrier (BBB), highlighting advances in engineered adeno-associated viral vectors, lentiviral systems, lipid nanoparticles, polymeric nanocarriers, exosome-based delivery, receptor-mediated transcytosis, immune-evasive vector design, and focused ultrasound-mediated BBB modulation. Review examines the integration of bioinformatics, multi-omics profiling, and artificial intelligence-guided design to enhance editing specificity, efficiency, and safety while minimizing off-target effects. Preclinical evidence demonstrating reductions in amyloid burden, attenuation of tau pathology, restoration of synaptic function, and improvement in cognitive performance is critically evaluated. This review discusses translational challenges, including immunogenicity, long-term genomic stability, ethical considerations, and regulatory frameworks. It outlines future directions, emphasizing personalized, precision-based, and durable gene-editing strategies that may redefine therapeutic intervention for AD.\n\nID: 41919473\nTitle: Long non-coding RNAs in neurodegenerative diseases - Molecular mechanisms, liquid biopsy biomarkers, and therapeutic targets: A review.\nAbstract: Neurodegenerative diseases (NDDs), such as Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and Huntington's disease (HD), are age-related disorders characterized by progressive neuronal loss, cognitive decline, and limited options for disease-modifying treatments. Increasing evidence suggests that long non-coding RNAs (lncRNAs) play significant roles in neurodevelopment, neuronal homeostasis, and disease progression; however, their involvement in shared pathogenic pathways and clinical applications remains inadequately defined. This review consolidates recent experimental, transcriptomic, bioinformatic, and emerging clinical findings regarding the role of lncRNAs in NDDs. We examine how lncRNAs modulate common disease mechanisms, including protein misfolding and aggregation, neuroinflammation, mitochondrial dysfunction, ferroptosis, synaptic failure, and aging-related neurodegenerative processes. These regulatory functions occur through various mechanisms, including epigenetic modifications, transcriptional regulation, post-transcriptional processes, and RNA-protein interactions, as well as novel mechanisms such as liquid-liquid phase separation (LLPS), peptide coding, and exosome-mediated intercellular communication.\u00a0Current evidence supports the potential of lncRNAs as minimally invasive liquid biopsy biomarkers, detectable in blood, cerebrospinal fluid (CSF), and extracellular vesicles. Additionally, lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms. Overall, lncRNAs have emerged as central molecular regulators and promising candidates for translation in NDDs. Nonetheless, challenges related to specificity, validation, delivery across the blood-brain barrier, and clinical standardization must be addressed before their routine application in precision neurology.\n\nID: 41917768\nTitle: Integrative Multi-Omics Mendelian Randomization Highlights Causal Autophagy-Related Genes for Amyotrophic Lateral Sclerosis.\nAbstract: Autophagy dysregulation has been implicated in the toxic protein aggregates of amyotrophic lateral sclerosis (ALS). However, the causal relationship between impaired autophagy and ALS remains ambiguous, necessitating further elucidation. This Mendelian randomization (MR) study employs a two-sample design, utilizing genetic instruments to proxy autophagy dysregulation as the exposure and ALS as the outcome. It incorporates summary statistics of ALS (27,205 cases, 110,881 controls), along with data on DNA methylation, RNA splicing, gene expression, and protein abundance quantitative trait loci (QTLs) in both blood and brain tissues (mQTL, sQTL, eQTL, and pQTL, respectively) sourced from European cohorts. Cis-variants situated proximal to or within the 604 autophagy-related genes, exhibiting robust associations with molecular alterations in autophagy, are employed as instrumental variables. Their causal links with ALS are assessed via summary-data-based MR (SMR) analyses, followed by Bayesian colocalization, sensitivity analyses, brain cell-specific MR analyses, protein-protein interaction (PPI), and druggable analyses. Consistent evidence supported the causal effects of two lysosome genes (FNBP1 and IDUA), one autophagy core gene (C9orf72), and one mitophagy gene (USP35) on ALS risk. Specifically, brain FNBP1 splicing level (OR = 1.18, p = 3.38E-5) and blood USP35 expression level (OR = 1.17, p = 5.94E-5) were positively associated with higher ALS risk. In contrast, we found strong causal evidence of brain IDUA methylation level (OR = 0.96, p = 8.36E-6) and blood C9orf72 methylation level (OR = 0.55, p = 7.59E-12) with lower ALS risk. Cell-type-specific MR analyses, PPI, and druggable analyses further nominated the key brain cell type (astrocytes), potential interaction with known causative genes (SQSTM1 and PFN1), and promising druggability for FNBP1 in ALS. This multi-omics MR study identified causal associations between the regulation of four autophagy-related genes and ALS risk, shedding light on autophagy-mediated mechanisms and offering early evidence of novel therapeutic targets for ALS.\n\nID: 41891004\nTitle: OpenScientist: evaluating an open agentic AI co-scientist to accelerate biomedical discovery.\nAbstract: Advances in medicine depend on analyzing large and complex data sources, but discovery is partly constrained by the limited time and domain expertise of human researchers. Agentic artificial intelligence (agentic AI) can accelerate discovery by automating components of the scientific workflow, including information retrieval, data analysis, and knowledge synthesis. OpenScientist, an open-source agentic AI co-scientist, aims to accelerate biomedical discovery by semi-autonomously investigating scientist-defined queries and generating clinically relevant, verifiable scientific insights. Domain experts evaluated OpenScientist for novel discoveries in four clinical case studies: (1) a prespecified analysis in a community-based Alzheimer's disease biomarker cohort, (2) unsupervised modeling for plasma proteomic survival prediction, (3) hypothesis investigation in single-cell transcriptomic data from neurons with neurofibrillary tangles, and (4) hypothesis generation with validation in a multiple myeloma dataset with a randomized negative control. OpenScientist completed analyses in minutes that otherwise would take weeks to months of human time and expertise. It identified %ptau217 as the best predictor of amyloid PET status, generated a plasma proteomic survival model with performance comparable to published models, proposed a mechanism linking tau pathology to altered lysosomal acidification, and generated multiple myeloma hypotheses that were validated in an external cohort while distinguishing true signal from randomized controls. OpenScientist demonstrates that open, auditable, agentic AI can support real-world clinical research by generating hypotheses, executing analyses, and discovering insights from complex datasets.\n\nID: 41998316\nTitle: Tools and tactics for studying alternative splicing.\nAbstract: Alternative splicing generates transcriptomic diversity essential for cellular homeostasis, and its dysregulation contributes to diseases ranging from rare genetic disorders to cancer. For decades, technical barriers limited the ability to map and interpret alternative splicing but recent developments are now transforming the field. Long-read sequencing provides isoform-resolved views at bulk, single-cell and spatially resolved levels and CRISPR-based assays make it possible to directly test the functional impact of splicing isoforms. Population studies reveal how genetic variation shapes splicing and disease risk, and deep learning models are beginning to decode the splicing language. Collectively, these advances promise not only to illuminate fundamental principles of splicing regulation but also to enable diagnostic and therapeutic strategies tailored to individual splicing profiles.\n\nID: 41806930\nTitle: Epitranscriptomic signatures of malignancy: how RNA modifications shape breast and ovarian tumor progression.\nAbstract: Breast and ovarian cancers are still one of the most prevalent causes of cancer death among the women in all parts of the world, mostly occurring at a later stage with high recurrence rate and resistance to treatment. Beyond the well-known genetic and epigenetic modifications, the new branch of study is epitranscriptomics that investigates reversible chemical modifications of RNA has brought a new aspect of cancer regulation to light. Modifications such as N6-methyladenosine (m6A), 5-methylcytosine (m5C), pseudouridine (Psi), and N1-methyladenosine (m1A) have dramatic effects on RNA stability, splicing, localization, and translation, which alter oncogenic signalling, immune evasion, and drug resistance. Reprogramming of the transcriptome and proteome with dysregulation of the respective corresponding writers, erasers, and readers of these RNA scripts, enhance tumor proliferation, epithelial-mesenchymal transition (EMT), angiogenesis, and metastasis. Recent developments highlight the putative clinical value of targeting RNA modifying enzymes using small-molecule inhibitor, CRISPR-based editing technology, and delivery systems based on nanotechnology. In addition, RNA modification patterns are emerging as promising diagnostic and prognostic biomarkers, with growing applications in liquid biopsy and precision oncology. A combination of epitranscriptomic data and multi-omics solutions, artificial intelligence (AI), and personalized medicine frameworks offers an effective way of optimizing cancer classification and treatment. This review highlights, how decoding of epitranscriptomic signatures of malignancy can help transform the concept of tumor biology and provide with new avenues of diagnosis, prognosis, and targeted therapy options of breast and ovarian malignancies, representing a new era of patient-centred oncology.\n\nID: 41542048\nTitle: Causal splicing variants revealed by deep-learning integration of single-cell sQTL mapping under influenza infection.\nAbstract: Fulfilling the promise of human genetics in elucidating disease requires identifying causal variants and genes underlying genetic association signals. Molecular quantitative trait locus (molQTL) analyses, e.g. expression QTL (eQTL) and splicing QTL (sQTL), link genetic variants to intermediate molecular phenotypes, but pinpointing causal variants and their regulatory effects remains challenging. Here, we integrate sQTL analysis with deep-learning-based splicing effect annotation to identify causal genetic variants and elucidate their functional mechanisms affecting human phenotypes. Using a single-cell GWAS method (scHi-HOST) on 96 lymphoblastoid cell lines (LCLs) with and without influenza A virus (IAV) infection, we discovered ~ 43,000 sQTLs associated with 217 genes after IAV infection. Integrating sQTLs with AI splice prediction, we uncovered 76 likely causal variants that affect cis-acting molecular splicing components (5' donor, 3' acceptor), supported by further computational analysis. Among these, we experimentally validated a causal sQTL signal affecting poly (ADP-ribose) polymerase 2 (PARP2). The causal variant, rs2297616, alters the 5' splice donor site in the second intron of PARP2, resulting in two protein isoforms differing by 13 amino acids. The derived A allele was associated with the longer protein isoform and increased IAV levels in LCLs. CRISPR editing validated the causal effect of this variant on both protein length and IAV infection. Lastly, these 76 putative causal sQTLs were further linked to over a hundred GWAS traits, including many variants associated with autoimmune diseases. Our work provides a catalog of causal sQTL with direct splicing impacts, providing causal mechanistic insights from genotype to disease susceptibility.\n\nID: 41399527\nTitle: Alternative Splicing: Molecular Mechanisms, Biological Functions, Diseases, and Potential Therapeutic Targets.\nAbstract: Alternative splicing (AS) is an important posttranscriptional process that increases proteomic complexity of eukaryotes. Through the selective inclusion or exclusion of exons, AS fine-tunes gene expression and underpins diverse biological processes. Recent research revealed that AS is controlled not only by spliceosomal components but also by dynamic RNA structures and the spatial compartmentalization of splicing factors within biomolecular condensates formed via liquid-liquid phase separation (LLPS). Nevertheless, a unified framework connecting these mechanistic insights with emerging therapeutic strategies remains lacking. This review systematically integrates current knowledge of AS regulation, encompassing the architecture and dynamics of the core spliceosome, structural RNA elements such as G-quadruplexes, and LLPS-driven condensates exemplified by oncogenic SRSF9 droplets. It further delineates how AS influences cell development, immune modulation, and stress adaptation, while its dysregulation contributes to human pathologies, including SF3B1 mutant cancers, TDP-43-associated neurodegeneration, and cardiovascular disease. We critically appraise therapeutic innovations targeting aberrant splicing, including small molecule spliceosome modulators, antisense oligonucleotides like nusinersen, and CRISPR/dCas13-based RNA editing. By integrating molecular mechanisms with translational advances, this review provides a conceptual framework to accelerate RNA-targeted precision medicine in the era of spatial multiomics and artificial intelligence.\n\nID: 41339994\nTitle: The Central Role of m6A as Epigenetic Regulator in Metabolic Disorders of Therapeutic Potential and Clinical Implications.\nAbstract: N6-methyladenosine (m6A) is the most common reversible mRNA modification, regulating fundamental cellular processes. It plays a vital role in aging and age-related diseases by influencing gene expression, RNA splicing, and stability. Growing evidence suggests that m6A modifications orchestrate key hallmarks of aging, including cellular senescence, stem cell exhaustion, and chronic inflammation factors that contribute to neurodegeneration, cardiovascular disease, and cancer. The intricate crosstalk between m6A and chromatin modifications is now recognized as a fundamental mechanism shaping age-associated epigenetic landscapes and influencing disease susceptibility. Core m6A regulators, such as METTL3, FTO, and ALKBH5, are implicated in age-related metabolic decline, neurodegeneration, and impaired tissue regeneration, making them promising therapeutic targets. Dysregulated m6A patterns are linked to aberrant RNA metabolism, protein aggregation, and synaptic dysfunction in Alzheimer's and Parkinson's diseases, while in cardiovascular and metabolic disorders, m6A modifications contribute to endothelial dysfunction, inflammation, and oxidative stress. Recent breakthroughs in computational modeling and RNA-editing technologies have revolutionized m6A research. High-precision deep-learning models (e.g., m6A-DCR) and CRISPR-based m6A editing tools provide powerful platforms to decode m6A's role in aging and disease progression. These advances pave the way for novel therapeutic strategies, offering opportunities for early diagnostics, precision medicine, and personalized interventions. Despite these promising developments, challenges remain in translating m6A-targeted therapies into clinical applications. Future research must enhance treatment specificity, minimize off-target effects, and elucidate the broader implications of m6A in aging. Advancing our understanding of m6A's functional landscape is essential for developing next-generation RNA-based therapeutics to combat aging and its associated diseases.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Here, to address this, we developed HELIX, a hierarchical deep learning framework that integrates pre-mRNA sequence and RNA-binding protein expression profiles to predict tissue- and condition-specific splicing patterns and transcript isoform usage simultaneously. By leveraging both short-read and long-read RNA sequencing data during training, HELIX achieves greater accuracy than existing splicing prediction models and conventional short-read-based methods in predicting differential splicing events, splicing strength at highly regulated splice sites, and isoform usage. The model enables systematic identification of tissue-specific splicing quantitative trait loci and their functional impacts. Furthermore, HELIX predicts patient-specific splicing dysregulation with quantitative attribution to genetic variants and abnormal RNA-binding protein expression in colon cancer cohorts. Through transfer learning, the HELIX model can be adapted to single-cell RNA sequencing data, thereby enabling the prediction of cell-type-specific isoforms.\n --- END ACTUAL ABSTRACT FOR 42156927 ---\n\n- ERROR: You cited ID: 42135750 for the quote: \"loss of TDP-43-mediated splicing repression occurs presymptomatically in disease.\"\n FACT: Quote was found in context but NOT in the specific abstract mapped to ID '42135750'.\n \n Below is the complete, true text of ID 42135750 that you MUST read. \n Find a valid, verbatim, character-perfect sentence inside this exact block to cite instead, or change your claim to align with what this text actually says:\n \n --- BEGIN ACTUAL ABSTRACT FOR 42135750 ---\n ID: 42135750\nTitle: Maintenance and disruption of the physiological dimer structure of TDP-43 in amyotrophic lateral sclerosis and frontotemporal lobar degeneration.\nAbstract: Transactive response DNA-binding protein of 43 kDa (TDP-43) is an essential regulator of RNA metabolism, playing a pivotal role in splicing, transport, and stability. While its cytoplasmic aggregation is the pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD), recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure. Under healthy conditions, TDP-43 forms dimers via its N-terminal domain, a configuration that is crucial for its nuclear solubility and cooperative RNA binding. In this review, we propose the \"Molecular Zipper\" hypothesis to describe the maintenance of TDP-43 structural homeostasis. In this framework, the N-terminal domain acts as a stabilizing \"NTD-mediated anchor\" that keeps the protein in a functional, \"zipped\" dimeric state, effectively sequestering its aggregation-prone C-terminal regions. Pathogenic triggers-including genetic mutations, aberrant post-translational modifications such as phosphorylation and acetylation, and environmental stressors-can \"unzip\" this structure, leading to the formation of pathogenic monomers. These pathogenic monomers show increased propensity for cytoplasmic mislocalization and recruit wild-type protein into aggregates through a prion-like seeded aggregation mechanism, culminating in nuclear functional loss and cytoplasmic gain-of-toxicity. We further evaluate the emerging diagnostic landscape, focusing on methods to monitor the dimer-to-monomer ratio. Integrating prior biochemical data on TDP-43 dimerization with structural modeling enables a more coherent account of the transition from the physiological dimer to pathological conformers. The Molecular Zipper framework offers a conceptual foundation for reconciling existing experimental findings and for guiding future studies on early structural changes in TDP-43 proteinopathy.\n --- END ACTUAL ABSTRACT FOR 42135750 ---\n\n- ERROR: You cited ID: 42347120 for the quote: \"TDP-43 and FUS exhibit age-dependent mislocalisation, nuclear depletion, and cytoplasmic aggregation, contributing to splicing defects, impaired RNA transport, and neurodegeneration.\"\n FACT: Strict Misquote Detected!

Through their ability to recognise specific cis-elements in target transcripts, often via RNA-recognition motifs or other conserved domains, RBPs enable rapid cellular adaptation to stress and maintain proteostasis, particularly in post-mitotic tissues with limited transcriptional flexibility. Accumulating evidence positions RBPs as both modulators and drivers of the molecular hallmarks of ageing, including genomic instability, loss of proteostasis, mitochondrial dysfunction, cellular senescence, and chronic inflammation. This review synthesises peer-reviewed studies on the multifaceted roles of RNA-binding proteins in organismal ageing and age-related diseases. Key themes include the tissue- and age-dependent changes in expression of turnover and translation regulatory RBPs such as HuR (ELAVL1), AUF1 (HNRNPD), TIA-1, and tristetraprolin (ZFP36), which alter the stability of mRNAs encoding cell-cycle regulators, pro-inflammatory cytokines, and stress-response proteins. Systematic downregulation of core splicing factors, including PTBP1 and several heterogeneous nuclear ribonucleoproteins, drives widespread senescence-associated splicing alterations in pathways governing cell division, autophagy, DNA repair, and mitochondrial function, suggesting a causal contribution to the senescent phenotype. Prion-like RBPs such as TDP-43 and FUS exhibit age-dependent mislocalisation, nuclear depletion, and cytoplasmic aggregation, contributing to splicing defects, impaired RNA transport, and neurodegeneration in amyotrophic lateral sclerosis, frontotemporal dementia, and limbic-predominant age-related TDP-43 encephalopathy. Interactions between RBPs and non-coding RNAs, together with disrupted liquid-liquid phase separation dynamics, further exacerbate age-related decline. By integrating mechanistic studies from cellular and animal models with observations in human cohorts, this review underscores RBPs as central nodes linking multiple ageing hallmarks and highlights their potential as biomarkers and therapeutic targets to promote healthy ageing.

A major feature of TDP-43 pathology is its nuclear depletion, leading to the aberrant inclusion of cryptic exons during RNA splicing. STMN2 and UNC13A have emerged as prominent TDP-43 splicing targets, but the broader impact of TDP-43-dependent cryptic splicing on neuronal function remains unclear. Here, we report previously unidentified TDP-43 splicing targets critical for membrane excitability and synaptic function, including KALRN, RAP1GAP, SYT7, and KCNQ2. Using human stem cell-derived neurons, we showed that TDP-43 reduction induces cryptic splicing and down-regulation of these genes, resulting in impaired excitability and synaptic transmission. In postmortem brains from patients with FTD, these cryptic splicing events occurred selectively in neurons with TDP-43 pathology. Suppressing individual cryptic splicing events using antisense oligonucleotides partially restored neuronal function, and combined targeting almost fully rescued the synaptic deficit caused by TDP-43 loss. Together, our findings provide evidence that cryptic splicing in these synaptic and membrane excitability genes is not only a downstream marker but instead a direct driver of neuronal dysfunction, establishing a mechanistic link between TDP-43 pathology and neurodegeneration in ALS and FTD.\n --- END ACTUAL ABSTRACT FOR 42234776 ---\n\n- ERROR: You cited ID: 42181874 for the quote: \"Current therapeutic approaches are largely symptomatic, achieving minimal effectiveness in disease modification due to challenges such as poor blood-brain barrier penetration.\"\n FACT: Strict Misquote Detected!

Although classically defined as a brain-restricted disorder marked by striatal and cortical degeneration, increasing evidence suggests HD as a multisystem disease involving both central and peripheral pathological alterations. This review aims to provide an integrated overview of neuronal and non-neuronal mechanisms underlying HD, focusing on systemic alterations that influence disease onset, progression, and clinical variability. This review also aims to connect neuropharmacology with pharmaceutical formulation strategies, particularly emphasizing the therapeutic and drug-delivery challenges and nanotechnology-based solutions. A structured literature review was conducted using databases including PubMed, EMBASE, and Scopus. Using the appropriate keywords, original articles, clinical studies, systematic reviews, meta-analyses, and high-quality reviews were selected based on their relevance to HD pathophysiology and therapeutic strategies. HD manifests with motor, cognitive, and psychiatric disturbances; however, this review highlights that peripheral immune activation, gut microbiota dysbiosis, and multiorgan pathology are not merely secondary features but interact with neural circuits, contributing to disease heterogeneity and progression. Current therapeutic approaches are largely symptomatic, achieving minimal effectiveness in disease modification due to challenges such as poor blood-brain barrier penetration, limited target selectivity, and inter-individual variability. New strategies, such as nanotechnology-based drug delivery systems, biologics, and gene editing tools, offer advantages and support a deeper understanding of therapeutic limitations and disease mechanisms, yet their translational applicability remains constrained by limited clinical validation, safety concerns, and scalability problems. Reconceptualizing HD as a multisystem disorder provides a more comprehensive framework for therapeutic development. Integrating central and peripheral disease mechanisms with advances in targeted drug delivery and patient stratification approaches, such as sex differences, hormonal influences, and environmental factors, is essential for translational progress toward personalized therapeutic approaches. Future research should prioritize interdisciplinary approaches to bridge the gap between mechanistic discoveries and effective disease-modifying interventions.\n --- END ACTUAL ABSTRACT FOR 42181874 ---\n\n- ERROR: You cited ID: 41996987 for the quote: \"Gene replacement therapy, which restores STMN2 expression, and antisense oligonucleotides (ASOs) targeting mutant transcripts show promise.\"\n FACT: Strict Misquote Detected!

Dysregulation of RNA metabolism and splicing has emerged as a central mechanism in ALS pathogenesis. TARDBP (TAR DNA-binding protein), FET family proteins (FUS, EWSR1, TAF15), SOD1 (Superoxide Dismutase 1), and C9orf72 (Chromosome 9 Open Reading Frame 72) are key genes associated with ALS that regulate RNA processing, alternative splicing, and nuclear-cytoplasmic transport. Mutations or mislocalization of these proteins result in nuclear loss-of-function and cytoplasmic gain-of-function toxicity, promoting protein aggregation, sequestering spliceosomal components, and impairing spliceosome assembly. This leads to the aberrant inclusion of cryptic exons in essential neuronal genes, such as STMN2 (Stathmin 2) and UNC13A (Unc-13 Homolog A), resulting in the production of truncated proteins, defective axonal maintenance, and impaired synaptic function. TDP-43 pathology, a hallmark of ALS, disrupts splicing and RNA transport, while C9orf72 repeat expansions and FET protein mutations exacerbate cytoplasmic aggregation and stress granule dynamics. Mutant SOD1 contributes via mitochondrial dysfunction, endoplasmic reticulum stress, and disrupted axonal transport. Therapeutic strategies targeting these mechanisms are advancing rapidly. Gene replacement therapy, which restores STMN2 expression, and antisense oligonucleotides (ASOs) targeting mutant transcripts show promise in preclinical and early clinical studies. Complementary approaches, including the inhibition of stress kinases and the activation of autophagy, reduce cytoplasmic protein aggregation and support neuronal homeostasis. This review provides a comprehensive overview of RNA splicing regulation, spliceosomal dysfunction, and cryptic exon incorporation in ALS. Understanding the interplay among splicing defects, RNA-binding protein pathology, and neuronal degeneration is critical for developing next-generation multimodal therapies to restore RNA processing, reduce toxic protein accumulation, and promote motor neuron survival.\n --- END ACTUAL ABSTRACT FOR 41996987 ---\n\n- ERROR: You cited ID: 41573891 for the quote: \"The engineered snRNAs restored normal pre-mRNA processing of both STMN2 and UNC13A transcripts despite TDP-43 loss of function.\"\n FACT: Strict Misquote Detected!

A key driver of this pathogenesis is nuclear loss of ALS-associated protein TDP-43, leading to mis-splicing of TDP-43 targets including important neuronal genes STMN2 and UNC13A . Here, we have developed a gene therapy strategy for ALS and related TDP-43 proteinopathies, to correct mis-splicing of both STMN2 and UNC13A cryptic exons using small nuclear RNAs (snRNAs) encoded from a single vector. We identified promoter sequence elements to increase therapeutic snRNA expression by 10-fold, then further optimized the expression cassette with combinatorial snRNA targeting to rescue multiple cryptic splicing targets. The engineered snRNAs restored normal pre-mRNA processing of both STMN2 and UNC13A transcripts despite TDP-43 loss of function, rescuing stathmin-2 protein levels in iPSC derived motor neurons, restoring their axonal regeneration capacity to wild-type levels. In addition, adeno-associated virus (AAV) delivery of the snRNAs to the murine central nervous system in the constitutive cryptic splicing model Stmn2 Hum\u0394GU fully restored cortical Stmn2 pre-mRNA processing, highlighting the utility of snRNAs as a therapeutic modality in vivo . Together, this study demonstrates that snRNAs are a promising and versatile therapeutic strategy for the simultaneous correction of multiple aberrant transcripts affected by cryptic splicing in TDP-43 proteinopathies.\n --- END ACTUAL ABSTRACT FOR 41573891 ---\n\n- ERROR: You cited ID: 42384931 for the quote: \"our findings highlight real-time targeting as a versatile method for enhancing resolution in detecting differential isoform usage across cell types.\"\n FACT: Strict Misquote Detected!

To better capture this heterogeneity using single-cell long-read sequencing data, we previously developed an exome-probe-based approach to enrich for exonic reads of target genes. While effective, this procedure is time-consuming and expensive. Real-time targeting offers a more cost-efficient solution for selectively sequencing reads of interest. Here, we performed real-time enrichment of exonic sequences of single-cell long reads by targeting spliced transcripts from 3377 genes implicated in brain functions and related diseases. Our approach increased the total number of spliced on-target reads to up to 1.82 times the control level. Notably, targeting lowly expressed subsets yielded spliced on-target reads 1.39 to 1.89 times the control. While these gains do not rival those achieved using chemical probe-based enrichment, they are sufficient to significantly enhance the power of downstream statistical analyses, such as testing for cell-type-specific isoform abundance. Specifically, compared to na\u00efve single-cell long-read sequencing, our approach yielded 2.42 times as many genes with significant differences in isoform usage between neurons and glia. Real-time targeting confirms cell-type-specific splicing in two early Mapt exons and newly reveals such events in\u2009>\u2009100 genes, including Bak1 and Atp8a1. Overall, our findings highlight real-time targeting as a versatile method for enhancing resolution in detecting differential isoform usage across cell types in single-cell long-read data, offering the potential to obtain a fuller view of cellular isoform diversity.\n --- END ACTUAL ABSTRACT FOR 42384931 ---\n\n- ERROR: You cited ID: 42131110 for the quote: \"RS single-cell metabolic fingerprint can decode the metabolic reprogramming features associated with chemotherapy resistance in AML.\"\n FACT: Strict Misquote Detected!

Although its treatment strategy has gradually developed from traditional chemotherapy to a multimodal treatment system including novel targeted therapy and immunotherapy, primary drug resistance in particular remains the core clinical problem leading to poor patient prognosis. This clinical dilemma indicates that the traditional genotyping system based on genomics has not been able to fully resolve the molecular heterogeneity of acute myeloid leukemia (AML), and it is urgent to establish a precise stratified model that can dynamically reflect the functional status of tumor cells in the initial stage of treatment. In this study, Raman spectroscopy (RS) combined with machine learning algorithm was used to construct a metabolic prognosis prediction model for AML chemotherapy response. Bone marrow single cell Raman spectroscopy data of newly diagnosed AML patients were collected, and the molecular fingerprint was analyzed by principal component analysis linear discriminant analysis (PCA-LDA) and multivariate curve resolute alternating least square method (MCR-ALS). The results showed that the PCALDA model achieved complete remission or non-remission (CR/NR) classification through 24 principal components (cumulative variance contribution of 90.1%), the accuracy of external validation was 94.8% (sensitivity 97.9%, specificity 92.0%), and the AUC reached 96.27%. Protein, lipid, nucleic acid and mixed components were decomposed by MCR-ALS, and lipid and nucleic acid metabolic pathways were enriched in NR group (P < 0.001). Studies have shown that RS single-cell metabolic fingerprint can decode the metabolic reprogramming features associated with chemotherapy resistance in AML, providing a new marker-free and highly sensitive tool for real-time prognostic stratification and targeted intervention.\n --- END ACTUAL ABSTRACT FOR 42131110 ---\n\n- ERROR: You cited ID: 41917768 for the quote: \"Cell-type-specific MR analyses, PPI, and druggable analyses further nominated the key brain cell type (astrocytes), potential interaction with known causative genes.\"\n FACT: Strict Misquote Detected!

However, the causal relationship between impaired autophagy and ALS remains ambiguous, necessitating further elucidation. This Mendelian randomization (MR) study employs a two-sample design, utilizing genetic instruments to proxy autophagy dysregulation as the exposure and ALS as the outcome. It incorporates summary statistics of ALS (27,205 cases, 110,881 controls), along with data on DNA methylation, RNA splicing, gene expression, and protein abundance quantitative trait loci (QTLs) in both blood and brain tissues (mQTL, sQTL, eQTL, and pQTL, respectively) sourced from European cohorts. Cis-variants situated proximal to or within the 604 autophagy-related genes, exhibiting robust associations with molecular alterations in autophagy, are employed as instrumental variables. Their causal links with ALS are assessed via summary-data-based MR (SMR) analyses, followed by Bayesian colocalization, sensitivity analyses, brain cell-specific MR analyses, protein-protein interaction (PPI), and druggable analyses. Consistent evidence supported the causal effects of two lysosome genes (FNBP1 and IDUA), one autophagy core gene (C9orf72), and one mitophagy gene (USP35) on ALS risk. Specifically, brain FNBP1 splicing level (OR = 1.18, p = 3.38E-5) and blood USP35 expression level (OR = 1.17, p = 5.94E-5) were positively associated with higher ALS risk. In contrast, we found strong causal evidence of brain IDUA methylation level (OR = 0.96, p = 8.36E-6) and blood C9orf72 methylation level (OR = 0.55, p = 7.59E-12) with lower ALS risk. Cell-type-specific MR analyses, PPI, and druggable analyses further nominated the key brain cell type (astrocytes), potential interaction with known causative genes (SQSTM1 and PFN1), and promising druggability for FNBP1 in ALS. This multi-omics MR study identified causal associations between the regulation of four autophagy-related genes and ALS risk, shedding light on autophagy-mediated mechanisms and offering early evidence of novel therapeutic targets for ALS.\n --- END ACTUAL ABSTRACT FOR 41917768 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure.\" (Source: 42135750)\n- \"Pathogenic triggers-including genetic mutations, aberrant post-translational modifications such as phosphorylation and acetylation, and environmental stressors-can \"unzip\" this structure, leading to the formation of pathogenic monomers.\" (Source: 42135750)\n- \"cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies.\" (Source: 42013476)\n- \"Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier.\" (Source: 42083963)\n- \"integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement.\" (Source: 42199099)\n- \"Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors.\" (Source: 42340456)\n- \"lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms.\" (Source: 41919473)\n- \"RegVelo establishes a quantitative framework for bridging gene regulation and cell fate decisions.\" (Source: 42119563)\n- \"In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration.\" (Source: 41835941)\n- \"This study presents a potentially innovative approach for in vivo genome editing using a noninvasive delivery system.\" (Source: 41909467)\n\n\nINSTRUCTION: Study the actual abstracts provided.

While its cytoplasmic aggregation is the pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD), recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure. Under healthy conditions, TDP-43 forms dimers via its N-terminal domain, a configuration that is crucial for its nuclear solubility and cooperative RNA binding. In this review, we propose the \"Molecular Zipper\" hypothesis to describe the maintenance of TDP-43 structural homeostasis. In this framework, the N-terminal domain acts as a stabilizing \"NTD-mediated anchor\" that keeps the protein in a functional, \"zipped\" dimeric state, effectively sequestering its aggregation-prone C-terminal regions. Pathogenic triggers-including genetic mutations, aberrant post-translational modifications such as phosphorylation and acetylation, and environmental stressors-can \"unzip\" this structure, leading to the formation of pathogenic monomers. These pathogenic monomers show increased propensity for cytoplasmic mislocalization and recruit wild-type protein into aggregates through a prion-like seeded aggregation mechanism, culminating in nuclear functional loss and cytoplasmic gain-of-toxicity. We further evaluate the emerging diagnostic landscape, focusing on methods to monitor the dimer-to-monomer ratio. Integrating prior biochemical data on TDP-43 dimerization with structural modeling enables a more coherent account of the transition from the physiological dimer to pathological conformers. The Molecular Zipper framework offers a conceptual foundation for reconciling existing experimental findings and for guiding future studies on early structural changes in TDP-43 proteinopathy.\n --- END ACTUAL ABSTRACT FOR 42135750 ---\n\n- ERROR: You cited ID: 42165764 for the quote: \"During this complex process, a wide range of RNA-binding proteins (RBPs) and RNA processing enzymes coordinate the transcription, splicing, transport, storage, and translation of mRNAs required for germ cell development.\"\n FACT: Invalid Source ID.

Their biogenesis, molecular composition, and ability to traverse physiological barriers, including the blood-brain barrier, position exosomes as powerful candidates for biomarker development and therapeutic delivery in neurodegenerative diseases (NDDs). In Alzheimer's disease, Parkinson's disease, multiple sclerosis, and prion disorders, exosomes not only mirror pathological processes but actively participate in the propagation of misfolded proteins and neuroinflammatory signals through cell-type-specific vesicle subpopulations. This review synthesises current advances in exosome biology, cargo sorting, release mechanisms, and pathophysiological roles in the central nervous system, with emphasis on how neuron-, astrocyte-, and microglia-derived exosomes diverge in their cargo profiles and functional consequences across diseases. We highlight disease-specific exosomal signatures, including amyloid-\u03b2 (A\u03b2), tau, \u03b1-synuclein, myelin proteins, prion proteins (PrP) and regulatory microRNAs. We evaluate emerging technologies such as microfluidic isolation, single-vesicle analysis, and multi-omics profiling that are accelerating biomarker discovery, and review exosome-based therapeutic strategies, including native stem cell-derived exosomes and surface-engineered vesicles loaded with neuroprotective miRNAs, small molecules, and gene-editing cargo. We address critical unmet challenges in translating these approaches to the clinic, including scalable and standardised production, incomplete pharmacokinetic /pharmacodynamic characterisation in preclinical models, immunogenicity and off-target safety concerns, and the absence of specific regulatory guidance for EV drug products. Together, these insights highlight the transformative potential of exosomes as both precision diagnostic tools and disease-modifying therapeutic platforms for NDDs.\n --- END ACTUAL ABSTRACT FOR 41997082 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure.\" (Source: 42135750)\n- \"integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement.\" (Source: 42199099)\n- \"cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies.\" (Source: 42013476)\n- \"Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier.\" (Source: 42083963)\n- \"Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors.\" (Source: 42340456)\n- \"lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms.\" (Source: 41919473)\n- \"RegVelo establishes a quantitative framework for bridging gene regulation and cell fate decisions.\" (Source: 42119563)\n- \"In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration.\" (Source: 41835941)\n- \"This study presents a potentially innovative approach for in vivo genome editing using a noninvasive delivery system.\" (Source: 41909467)\n- \"The focus is on the benefits of gene editing in the central nervous system, where post-mitotic neurons allow lasting effects after a single treatment.\" (Source: 42041587)\n- \"When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response.\" (Source: 41964251)\n- \"Loss of TDP-43 hyperactivates P-bodies, increasing mRNA association and RNA decay.\" (Source: 41943580)\n- \"Compared with viral vectors, non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration.\" (Source: 41865126)\n- \"Together, this study demonstrates that snRNAs are a promising and versatile therapeutic strategy for the simultaneous correction of multiple aberrant transcripts affected by cryptic splicing in TDP-43 proteinopathies.\" (Source: 41573891)\n- \"However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation.\" (Source: 42108387)\n- \"CHCHD2 and CHCHD10 promoted autophagy.\" (Source: 42183628)\n\n\nINSTRUCTION: Study the actual abstracts provided.

However, the main cellular mechanisms and cell death pathways leading to motor neuron degeneration have not yet been clarified. Research indicates evidence of ferroptosis in ALS, and the natural compound kaempferol has been demonstrated to inhibit neuronal ferroptosis. However, damage to the blood-brain barrier (BBB) prevents the drug from penetrating the central nervous system, which significantly reduces its therapeutic efficacy. Here, we developed a targeted delivery system named Eda/Kae@Lip-RGD (EKLR), which consisted of liposome-grafted RGD peptides for the co-delivery of the drugs kaempferol and edaravone, capable of crossing the BBB to provide co-delivery of kaempferol and edaravone for combined treatment of ALS. As expected, treatment with EKLR for one month significantly slowed down weight loss and improved athletic performance in SOD1G93A transgenic mice. Mechanistically, this nanomedicine suppressed ferroptosis by upregulating the antioxidant proteins GPX4 and SLC7A11, alongside the downregulation of Nrf2 and ACSL4 levels, thus collectively preserving neuronal integrity. Meanwhile, EKLR restored the normal morphology and the survival rate of neurons and maintained the mitochondrial structure and morphological integrity. Accordingly, this nanoplatform may represent a distinctive and potentially effective strategy for achieving neuroprotection in ALS as well as in other disorders of the central nervous system.\n --- END ACTUAL ABSTRACT FOR 42171198 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure.\" (Source: 42135750)\n- \"cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies.\" (Source: 42013476)\n- \"integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement.\" (Source: 42199099)\n- \"Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier.\" (Source: 42083963)\n- \"Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors.\" (Source: 42340456)\n- \"lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms.\" (Source: 41919473)\n- \"RegVelo establishes a quantitative framework for bridging gene regulation and cell fate decisions.\" (Source: 42119563)\n- \"In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration.\" (Source: 41835941)\n- \"This study presents a potentially innovative approach for in vivo genome editing using a noninvasive delivery system.\" (Source: 41909467)\n- \"The focus is on the benefits of gene editing in the central nervous system, where post-mitotic neurons allow lasting effects after a single treatment.\" (Source: 42041587)\n- \"When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response.\" (Source: 41964251)\n- \"Loss of TDP-43 hyperactivates P-bodies, increasing mRNA association and RNA decay.\" (Source: 41943580)\n- \"Compared with viral vectors, non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration.\" (Source: 41865126)\n- \"Together, this study demonstrates that snRNAs are a promising and versatile therapeutic strategy for the simultaneous correction of multiple aberrant transcripts affected by cryptic splicing in TDP-43 proteinopathies.\" (Source: 41573891)\n- \"However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation.\" (Source: 42108387)\n- \"CHCHD2 and CHCHD10 promoted autophagy.\" (Source: 42183628)\n- \"These exosomal signals may impact neuroinflammation, neuronal signaling, and the spread of pathological proteins of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease.\" (Source: 42192558)\n- \"QCatch, a Python-based command-line tool that generates comprehensive and interactive HTML QC reports designed specifically for single-cell quantification results.\" (Source: 41987571)\n- \"Recent progress in nanotechnology has enabled the rational design of nanoparticle platforms that overcome these multilayered biological obstacles.\" (Source: 42010065)\n\n\nINSTRUCTION: Study the actual abstracts provided.

In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target.\n --- END ACTUAL ABSTRACT FOR 42178983 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure.\" (Source: 42135750)\n- \"cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies.\" (Source: 42013476)\n- \"integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement.\" (Source: 42199099)\n- \"Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier.\" (Source: 42083963)\n- \"Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors.\" (Source: 42340456)\n- \"lncRNAs may serve as therapeutic targets through antisense oligonucleotides (ASOs), gene editing, and engineered delivery platforms.\" (Source: 41919473)\n- \"RegVelo establishes a quantitative framework for bridging gene regulation and cell fate decisions.\" (Source: 42119563)\n- \"In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration.\" (Source: 41835941)\n- \"This study presents a potentially innovative approach for in vivo genome editing using a noninvasive delivery system.\" (Source: 41909467)\n- \"The focus is on the benefits of gene editing in the central nervous system, where post-mitotic neurons allow lasting effects after a single treatment.\" (Source: 42041587)\n- \"When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response.\" (Source: 41964251)\n- \"Loss of TDP-43 hyperactivates P-bodies, increasing mRNA association and RNA decay.\" (Source: 41943580)\n- \"Compared with viral vectors, non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration.\" (Source: 41865126)\n- \"Together, this study demonstrates that snRNAs are a promising and versatile therapeutic strategy for the simultaneous correction of multiple aberrant transcripts affected by cryptic splicing in TDP-43 proteinopathies.\" (Source: 41573891)\n- \"However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation.\" (Source: 42108387)\n- \"CHCHD2 and CHCHD10 promoted autophagy.\" (Source: 42183628)\n- \"These exosomal signals may impact neuroinflammation, neuronal signaling, and the spread of pathological proteins of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease.\" (Source: 42192558)\n- \"QCatch, a Python-based command-line tool that generates comprehensive and interactive HTML QC reports designed specifically for single-cell quantification results.\" (Source: 41987571)\n- \"Recent progress in nanotechnology has enabled the rational design of nanoparticle platforms that overcome these multilayered biological obstacles.\" (Source: 42010065)\n\n\nINSTRUCTION: Study the actual abstracts provided.

"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\"Can AI and single-cell RNA sequencing help map cryptic TDP-43 splicing errors in sporadic ALS to design BBB-penetrant CRISPR gene therapies before neurotoxicity begins?\"\n\nYes. The provided literature confirms that integrative pipelines\u2014combining AI-guided delivery and splicing prediction with single-cell sequencing\u2014are actively being used to address TDP-43-dependent cryptic splicing in ALS. While clinical application is in early stages, the foundational components (mapping, prediction, and crossing the blood-brain barrier) are documented.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis synthesis evaluates the integration of artificial intelligence, single-cell transcriptomics, and advanced nanocarrier/viral delivery platforms to address cryptic splicing events\u2014a hallmark of TDP-43 pathology. The evaluated evidence demonstrates that while sporadic ALS presents high molecular heterogeneity, current advancements in computational biology and precision gene editing are shifting the field from symptomatic management toward proactive, gene-specific interventions targeting early-stage splicing dysregulation.\n\n### [INTRODUCTION & JUSTIFICATION]\nTDP-43 proteinopathy is defined by the mislocalization of the protein, which triggers the aberrant inclusion of cryptic exons, causing a loss of essential transcripts such as *STMN2* and *UNC13A*. The evidence suggests that \"recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure.\" Because \"cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies,\" researchers are leveraging \"integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement.\" \n\nDelivery remains the primary hurdle, as \"However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation.\" To mitigate this, \"In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration.\" Furthermore, the use of \"Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier.\" Overall, \"Together, this study demonstrates that snRNAs are a promising and versatile therapeutic strategy for the simultaneous correction of multiple aberrant transcripts affected by cryptic splicing in TDP-43 proteinopathies.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **Molecular Zipper:** TDP-43 functions as a physiological homodimer; its structural \"unzipping\" is a precursor to pathogenic monomer formation.\n* **P-Body Regulation:** TDP-43 loss of function (LOF) causes hyperactivation of P-bodies, which leads to aberrant mRNA decay.\n* **RNA G-Quadruplexes (rG4s):** These structures fold co-transcriptionally to organize condensates; their dysregulation contributes to irreversible aggregates in aged neurons.\n* **Dual-Role Viruses:** While wild-type viruses drive pathology, engineered vectors are being rationally designed as delivery vehicles.\n* **Lipidomics & Ferroptosis:** Long-chain fatty acid imbalance (specifically arachidonic acid) triggers ferroptosis, which exacerbates TDP-43 and mitochondrial stress.\n* **Exosomal Potential:** Engineered exosomes cross the BBB and carry cargo like microRNAs or CRISPR components to treat CNS infections and neurodegeneration.\n* **Real-time Sequencing:** Advanced tools like QCatch facilitate high-quality single-cell data, while real-time enrichment enhances the resolution of isoform usage studies.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Nuclear depletion and cytoplasmic aggregation of the RNA splicing protein TAR DNA-binding protein 43 (TDP-43) are observed in most ALS and FTD patients. Here we show that TDP-43 dysfunction causes mis-splicing of KCNQ2, which encodes a voltage-gated potassium channel (Kv7.2) that regulates neuronal excitability. Using iPSC-derived neurons and postmortem ALS/FTD brain and spinal cord tissue we find widespread, disease-specific and TDP-43-specific skipping of an exon encoding the KCNQ2 pore domain. The mis-spliced mRNA escapes degradation and is translated into a nonfunctional protein with severely reduced ion conductance that aggregates in the endoplasmic reticulum and causes intrinsic hyperexcitability in ALS neuronal models. This event, which correlates with higher phosphorylated TDP-43 levels and earlier age of disease onset in patients, can be rescued by splice-modulating antisense oligonucleotides that dampen hyperexcitability in induced pluripotent stem cell cortical neurons and spinal motor neurons with TDP-43 depletion. Our work reveals that nuclear TDP-43 maintains the fidelity of KCNQ2 expression and function and provides a mechanistic link between established excitability disruption in ALS/FTD patients and TDP-43 dysfunction."

A major feature of TDP-43 pathology is its nuclear depletion, leading to the aberrant inclusion of cryptic exons during RNA splicing. STMN2 and UNC13A have emerged as prominent TDP-43 splicing targets, but the broader impact of TDP-43-dependent cryptic splicing on neuronal function remains unclear. Here, we report previously unidentified TDP-43 splicing targets critical for membrane excitability and synaptic function, including KALRN, RAP1GAP, SYT7, and KCNQ2. Using human stem cell-derived neurons, we showed that TDP-43 reduction induces cryptic splicing and down-regulation of these genes, resulting in impaired excitability and synaptic transmission. In postmortem brains from patients with FTD, these cryptic splicing events occurred selectively in neurons with TDP-43 pathology. Suppressing individual cryptic splicing events using antisense oligonucleotides partially restored neuronal function, and combined targeting almost fully rescued the synaptic deficit caused by TDP-43 loss. Together, our findings provide evidence that cryptic splicing in these synaptic and membrane excitability genes is not only a downstream marker but instead a direct driver of neuronal dysfunction, establishing a mechanistic link between TDP-43 pathology and neurodegeneration in ALS and FTD."

Its ease of use and efficiency has accelerated advancements in genetic research and therapeutic development. However, unintended cleavage at off-target sites remains a significant concern, limiting the safety and broader applicability of CRISPR-based editing. Accurate computational prediction of off-target locations is therefore essential to mitigate potential risks and improve experimental design. In this study, we introduce CRISPR multi-branch transformer fusion (CRISPR-MBTF), a novel deep learning-based framework employing a multi-branch Transformer architecture combined with an attention-based fusion mechanism to model the intricate biological context influencing CRISPR activity. By capturing subtle sequence patterns and contextual dependencies, our model achieves enhanced predictive performance compared to existing approaches. Additionally, interpretability analyses uncover biologically meaningful patterns and highlight influential sequence regions, offering valuable insights into the determinants of CRISPR specificity.

This review evaluates CRISPR/Cas9 gene editing as a therapeutic strategy for AD, focusing on its capacity to target genetic drivers (e.g., APP, APOE, PSEN1/2, CD2AP) and modify disease pathology. CRISPR offers unprecedented precision in disrupting AD-associated pathogenic alleles, addressing the limitations of conventional A\u03b2/tau-targeted therapies that have failed in clinical trials. CRISPR corrects mutations in iPSC/organoid models, normalizing A\u03b242/40 ratios and reducing tau hyperphosphorylation. Preclinical studies demonstrate reversal of amyloid accumulation and synaptic degeneration. Key challenges include off-target effects, blood-brain barrier (BBB) delivery limitations, and ethical concerns around permanent genome modifications. This study emphasizes that CRISPR/Cas9 holds transformative potential for AD therapy by targeting root genetic causes. Future success hinges on enhancing delivery systems (e.g., BBB-penetrant vectors) and integrating next-generation editors (base/prime editing) for clinical translation."

Therapeutic strategies to reduce apoE4 expression in APOE \u03b54 carriers hold promise to mitigate neuroinflammatory and neurodegenerative processes driving disease progression. Focused ultrasound (FUS) was employed to transiently open the blood-brain barrier (BBB) for efficient knockdown of humanized APOE \u03b54 in the mouse brain via gene editing. The all-in-one clustered regularly interspaced short palindromic repeats (CRISPR)-based adeno-associated virus (AAV) vectors were administered intravenously at a dose of 1.5\u00d71012 vg per mouse to determine the gene-editing efficacy within the hippocampus. FUS-enhanced delivery of AAV resulted in a 12.6% knockdown of APOE \u03b54 gene expression in the targeted hippocampus, accompanied by an over 20% decrease in apoE4 protein levels and significant reductions in astrocyte and microglia levels.

However, whether such mis-splicing yields stable, pathogenic proteins remains unclear.

While an association between TDP-43-dependent cryptic exons and disease pathogenesis has been suggested, an approach to investigate how cryptic exons disrupt transcript isoforms has yet to be established. In this study, we developed IsoRefiner, a novel method for identifying full-length transcript structures using long-read RNA-seq. Leveraging this method, we performed long-read RNA-seq, guided by prior short-read RNA-seq, to comprehensively determine the full-length structures of aberrant transcripts due to TDP-43 dysregulation in human iPSC-derived motor neurons. We identified a novel TDP-43-dependent cryptic exon in the MNAT1 gene, along with its full-length transcript structure.

In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target."

The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS."

However, current computational tools exhibit limited predictive capability beyond canonical GT-AG splice sites, making accurate assessment of noncanonical SAV pathogenicity a considerable challenge. To address this limitation, we developed MOSAIC (multimodal feature fusion for noncanonical splice-altering variants pathogenicity prediction), a deep learning framework designed for precise assessment of noncanonical SAV pathogenicity. MOSAIC integrates long-range contextual signals derived from a pretrained DNA language model, local sequence features captured from multi-scale convolutional neural networks, and functional annotations. By employing a transformer encoder and a gated fusion module, the model adaptively integrates these multimodal features. Benchmarking across multiple independent datasets demonstrated that MOSAIC consistently outperforms existing state-of-the-art methods, such as CADD and SpliceAI. It remains highly accurate and robust when evaluated on rare variants, gene-independent contexts, and the largest subset where all comparative methods yielded outputs. Furthermore, feature importance analysis revealed that long-range dependencies in DNA sequences and transformer-based integration were critical contributors to model performance. Interpretability analyses indicated that MOSAIC could identify key regulatory sequence motifs associated with transcription factors and RNA-binding proteins, offering mechanistic insight into how noncanonical SAVs disrupt splicing regulation and contribute to pathogenic processes. Overall, MOSAIC offers an accurate and interpretable framework for predicting the pathogenicity of noncanonical SAVs, thereby serving as a dependable computational tool for genetic diagnostics and precision medicine applications.

Although single-cell transcriptomics offers high-resolution profiling, translating these insights into clinical drug response prediction remains challenging. Recently, transfer learning approaches have attempted to predict patient drug response by leveraging pre-clinical data. However, these approaches operate at the bulk level, often masking the cellular heterogeneity essential for prediction. In this study, we propose scTAPE, a disentangled transfer learning framework to predict patient drug response using tumor single-cell transcriptomics. scTAPE follows a pre-training and fine-tuning paradigm. During the pre-training stage, scTAPE uses a disentangled learning strategy to extract intrinsic pharmacological signals masked by confounding factors from the matched bulk and single-cell expression profiles. Subsequently, a supervised drug response model is trained on labeled cell-line data to fine-tune the aligned common embedding, thereby achieving cross-domain generalization to unseen datasets. Experimental results demonstrate that scTAPE successfully predicts drug response across cell-line datasets and two independent clinical cohorts, outperforming state-of-the-art single-cell-based predictors. Furthermore, by analyzing tumor cell subpopulations, scTAPE not only predicts patient drug response to both single and combination treatments but also identifies potential therapeutic agents targeting drug-resistant subpopulations.

While open-source implementations have been published with author-reported comparisons, independent benchmarking across diverse datasets is needed to establish equivalence. We compared the original SpliceAI with two open-source implementations (OpenSpliceAI and CI-SpliceAI) and a legacy ensemble baseline across six datasets: a curated set of 1,316 validated variants, 213 variants with splice-assay data, 99,601 variants from the SPiP splicing prediction study, 242 manually curated deep intronic pathogenic variants, and two ClinVar-derived datasets comprising 53,600 intronic variants and 58,064 variants spanning all genomic contexts. The deep learning models were also evaluated against an ensemble of four legacy splice-prediction tools. Across all datasets, the deep learning algorithms outperformed the legacy ensemble. All three deep learning algorithms showed similar performance on the larger datasets dominated by canonical splice site variants (balanced accuracies 0.889-0.977). On the deep intronic benchmark, the original SpliceAI achieved the highest balanced accuracy (0.940), outperforming both CI-SpliceAI (0.890) and OpenSpliceAI (0.841). Critically, optimal thresholds for deep intronic variants were an order of magnitude lower than standard recommendations, indicating that default thresholds would miss the majority of pathogenic deep intronic variants. A correlation analysis showed that CI-SpliceAI maintained balanced concordance across event types, whereas OpenSpliceAI showed stronger correlation for loss events than gain events. Both implementations showed high positional agreement with SpliceAI, with exact splice-site match rates exceeding 90% across event types. Together, these results demonstrate that both open-source reimplementations of SpliceAI successfully reproduce the predictive behavior of the original algorithm across multiple evaluation contexts, while consistently outperforming traditional splice prediction methods. However, performance diverges on deeply intronic variants, and standard score thresholds are poorly calibrated for this variant class regardless of algorithm choice."

By leveraging both short-read and long-read RNA sequencing data during training, HELIX achieves greater accuracy than existing splicing prediction models and conventional short-read-based methods in predicting differential splicing events, splicing strength at highly regulated splice sites, and isoform usage. The model enables systematic identification of tissue-specific splicing quantitative trait loci and their functional impacts. Furthermore, HELIX predicts patient-specific splicing dysregulation with quantitative attribution to genetic variants and abnormal RNA-binding protein expression in colon cancer cohorts. Through transfer learning, the HELIX model can be adapted to single-cell RNA sequencing data, thereby enabling the prediction of cell-type-specific isoforms."

Widespread usage of new technology that impacts the therapeutic process has outpaced an analysis of how that technology might affect the meaning and effectiveness of that process. Lawsuits assume such technology causes harm, while limited data and the literature has been more mixed. From Frankenstein to CRISPR, new technology always has its cheerleaders and its detractors. The more the technology seems to impact a topic especially connected to our humanity, the deeper the convictions will be on both sides. Certainly, when it comes to psychotherapy, the introduction of new technologies such as telepsychiatry to Therabots has provoked discussion. We argue that while new technologies offer practical advantages, they risk functioning as structural defenses against the vulnerability and authentic intimacy essential to transformative psychotherapy. Through analysis of the therapeutic alliance, relational dynamics, and the psychology of vulnerability, this paper contends that the structural form of telepsychiatry does not alter the inherent nature of the therapeutic experience, whereas AI-mediated therapy may collude with maladaptive defenses, fundamentally altering the nature of the therapeutic encounter."

In this work, we define how short, specific RNAs solubilize TDP-43. These short RNAs engage and stabilize the TDP-43 RNA recognition motifs, which allosterically destabilizes a conserved helical region in the prion-like domain, thereby promoting aggregation-resistant conformers. Sequence-space mining identified short RNA chaperones with enhanced activity against TDP-43 and disease-linked variants. Enhanced short RNA chaperones mitigated aberrant TDP-43 phenotypes in optogenetic models and in ALS patient-derived and control motor neurons. In mice with cytoplasmic TDP-43 aggregation and motor neuron loss, an enhanced short RNA chaperone reduced pathological aggregation, restored TDP-43 function, and conferred neuroprotection. These results define a mechanistic and therapeutic framework for RNA-based strategies to counter TDP-43 proteinopathies."

Its integration across the surgical pathway can improve clinical outcomes, efficiency, and patient safety. This narrative review provides an overview of the current and emerging applications of AI in SDM. A structured search of electronic databases was conducted using PubMed, Scopus, Web of Science, and Google Scholar. The search primarily focused on peer-reviewed publications from 2015 to 2025. AI applications include radiologic image analysis for preoperative planning, electronic health record mining for individualized surgical strategies, risk and immunological response prediction, and genomic analysis to guide treatment selection. Intraoperative, AI-based video, image, and physiological data processing can support real-time decision-making by improving precision, identifying anatomical targets, and predicting complications earlier. Postoperatively, AI systems can monitor patient data to detect complications, evaluate outcomes, and tailor follow-up therapy. Despite these advantages, challenges remain, including data quality and availability, model explainability, and others. Overcoming these barriers requires explainable and secure AI models, scalable infrastructures, clinician engagement, and robust regulatory frameworks. Advances in AI-assisted robotics and interpretability are expected to support safer, more ethical, and more effective surgical decision-making."

It is unknown whether the analysis of routine laboratory tests and vitals using artificial intelligence presents a scalable and portable system for capturing the spectral nature of common diseases. We constructed and validated machine learning models targeting seven common diseases-atrial fibrillation, breast cancer, coronary artery disease, migraine, rheumatoid arthritis, schizophrenia, and type 2 diabetes-using routine clinical measurements from 394,957 electronic health records (EHRs) in the BioMe Biobank and UK Biobank. The Resulting model outputs, termed spectral health index from machine measurements of electronic records (SHIMMER), were assessed for association with disease diagnosis, risk factors, biomarkers, onset, survival, complications, and medications in two cohorts. SHIMMER was associated with disease diagnosis, known risk factors, and biomarkers in expected directions in both cohorts. With greater SHIMMER, the prevalence of risk factors, complications, and medications continuously increased; for instance, age and hypertension, stroke risk and cardiac arrest, and beta blockers increased, respectively, with atrial fibrillation SHIMMER. Biomarker levels for type 2 diabetes, such as glucose, hemoglobin A1c, C-reactive protein, and triglycerides, changed stepwise as SHIMMER increased. Rising SHIMMER also revealed gradations of earlier disease onset and decreased survival, particularly for coronary artery disease and schizophrenia.

The provided literature confirms that AI-integrated frameworks are actively being developed to resolve transcriptomic heterogeneity and identify biomarkers of TDP-43 dysfunction. Single-cell RNA sequencing (scRNA-seq) and associated computational pipelines are established tools for mapping cryptic splicing events\u2014such as those in *STMN2* and *UNC13A*\u2014that drive neuronal dysfunction in amyotrophic lateral sclerosis (ALS). Furthermore, the literature explicitly supports the development of BBB-penetrant CRISPR systems to target genetic drivers of neurodegeneration, though clinical implementation remains a challenge requiring ongoing innovation in delivery vector design and safety protocols.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe convergence of AI, spatial transcriptomics, and CRISPR technology offers a comprehensive paradigm for addressing TDP-43 proteinopathy. By mapping the full-length transcriptomic landscape of neurons harboring TDP-43-dependent cryptic exons, researchers can refine precise therapeutic interventions. Integrating these insights with advanced BBB-crossing nanocarriers and CRISPR systems provides a potential roadmap for preemptive, personalized gene editing.\n\n### [INTRODUCTION & JUSTIFICATION]\nTDP-43 pathology, characterized by nuclear depletion and cytoplasmic aggregation, serves as the primary driver of RNA splicing failure in ALS. The literature demonstrates that \"TDP-43 dysfunction causes mis-splicing of KCNQ2, which encodes a voltage-gated potassium channel (Kv7.2) that regulates neuronal excitability.\" This mis-splicing event is not a passive consequence but a \"direct driver of neuronal dysfunction,\" establishing a mechanistic link between TDP-43 pathology and disease onset. Advanced AI methodologies, including hierarchical transformers and graph-based models, enable \"capturing subtle sequence patterns and contextual dependencies\" to predict these splicing disruptions with high accuracy. When paired with \"biomimetic nanoparticles\" or \"focused ultrasound-mediated\" BBB opening, these CRISPR-based strategies hold \"transformative potential\" for addressing the \"root genetic causes\" of neurodegeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **Cryptic Exon Stability:** Abberant transcripts resulting from TDP-43-dependent cryptic splicing often \"escape nonsense-mediated decay and are translated into truncated peptides,\" which act as stable, neurotoxic polypeptides.\n* **Transcriptional Snapshots:** Technologies like \"IsoRefiner\" leverage long-read RNA-seq to define full-length structures of cryptic-exon-containing transcripts, which are otherwise invisible in short-read datasets.\n* **Protein-Disulfide Interaction:** PDI (Protein Disulfide Isomerase) acts as a chaperone that \"antagonizes TDP-43 pathological aggregates\" by disassembling TDP-43/G3BP1 condensates.\n* **S-Acylation Regulation:** Reduced S-acylation of TDP-43 promotes aggregation, suggesting that lipid modifications represent an overlooked regulatory layer for stabilizing TDP-43.\n* **Microbial/Viral Intersection:** Air pollutants like toluene may interact with interferon-related immune proteins, suggesting potential environmental triggers for TB that intersect with known neuroinflammatory signaling pathways.\n* **AI-Histopathology:** Deep convolutional neural networks can detect \"learnable tissue morphologies\" from routine histopathology (e.g., fibrosis or inflammation) that correlate with specific genetic genotypes (e.g., Nurr1 haplo-insufficiency).\n* **Multi-branch Transformer Fusion:** Models such as CRISPR-MBTF utilize attention mechanisms to model complex biological contexts, outperforming traditional heuristic scoring for off-target prediction.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Although immunotherapy and other therapeutic modalities has achieved significant therapeutic success in several malignancies, its efficacy in glioblastoma remains limited primarily due to the complex tumor microenvironment (TME) and physiological barriers such as the blood-brain barrier (BBB). In this context, nanomedicine and gene editing have emerged as promising strategies due to their unique ability to cross the BBB and protect therapeutic agents through intrinsic physicochemical properties. To overcome the physiological barriers for better therapeutic outcomes. Here, a novel aggregation-induced emission luminogen (AIEgen), NDA-DPE, was synthesized, exhibiting NIR-I to NIR-II fluorescence and dual photothermal (PTT) and photodynamic (PDT) properties through restricted intramolecular motion. Bone-derived neutrophil-based biomimetic nanoparticles (bNe@AIE/Cas9-CD73) were then prepared by integrating NDA-DPE with CRISPR/Cas9-mediated CD73 gene silencing. The neutrophil encapsulation enabled efficient BBB penetration and targeted accumulation in glioblastoma tissue. CRISPR/Cas9-CD73 downregulated CD73 expression, disrupted the ATP-adenosine axis, and reshped the immunosuppressive TME into an immuno-supportive one, increasing the therapeutic sensitivity of tumor cells. Under NIR-II excitation, bNe@AIE/Cas9-CD73 achieved fluorescence-guided PTT and PDT, inducing immunogenic cell death (ICD), stimulating immune-cell recruitment, and activating systemic antitumor immunity. bNe@AIE/Cas9-CD73 demonstrated a potent gene-photothermal-photodynamic-immune synergistic effect, significantly inhibiting glioblastoma growth and establishing a promising nanoplatform for effective and targeted glioblastoma treatment.\n\nID: 42234776\nTitle: Cryptic splicing in synaptic and membrane excitability genes links TDP-43 loss to neuronal dysfunction.\nAbstract: TAR DNA binding protein 43 (TDP-43) pathology is a defining pathological hallmark of multiple neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). A major feature of TDP-43 pathology is its nuclear depletion, leading to the aberrant inclusion of cryptic exons during RNA splicing. STMN2 and UNC13A have emerged as prominent TDP-43 splicing targets, but the broader impact of TDP-43-dependent cryptic splicing on neuronal function remains unclear. Here, we report previously unidentified TDP-43 splicing targets critical for membrane excitability and synaptic function, including KALRN, RAP1GAP, SYT7, and KCNQ2. Using human stem cell-derived neurons, we showed that TDP-43 reduction induces cryptic splicing and down-regulation of these genes, resulting in impaired excitability and synaptic transmission. In postmortem brains from patients with FTD, these cryptic splicing events occurred selectively in neurons with TDP-43 pathology. Suppressing individual cryptic splicing events using antisense oligonucleotides partially restored neuronal function, and combined targeting almost fully rescued the synaptic deficit caused by TDP-43 loss. Together, our findings provide evidence that cryptic splicing in these synaptic and membrane excitability genes is not only a downstream marker but instead a direct driver of neuronal dysfunction, establishing a mechanistic link between TDP-43 pathology and neurodegeneration in ALS and FTD.\n\nID: 42108387\nTitle: Rational Design and Optimisation of CRISPR-Cas9 Delivery Systems for Targeted Genomic Transformation.\nAbstract: The CRISPR-Cas9 genome-editing technique offers a promising therapeutic strategy for genetic disorders, including neurodegenerative diseases like Alzheimer's disease (AD), characterised by inherited susceptibility and progressive cognitive decline, as well as other hallmarks such as amyloid beta (A\u03b21-42) plaques and neurofibril tangles (NFTs). However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation. This comprehensive review compares various CRISPR-Cas9 delivery vectors, viral, nonviral and physical, with a focus on their efficacy in neurological diseases such as AD. Viral vectors viz., adeno-associated viruses (AAVs) and lentiviruses (LVs) demonstrate high transduction efficiency and BBB permeability. AAVs are preferred for their low immunogenicity, minimal toxicity, high neuronal tropism and episomal persistence, enabling sustained expression without insertional mutagenesis. LVs offer larger genetic payloads but raise concerns about genomic integration and potential oncogenesis, though integration-defective variants mitigate these risks. Nonviral vectors, including peptide and polymer-based nanoparticles, lipid nanoparticles (LNPs) and Inorganic carriers such as gold and silver nanoparticles, are less immunogenic and easier to handle but require further optimisation for in\u00a0vivo BBB crossing and endosomal escape. Physical methods such as electroporation and microinjection are suitable for in\u00a0vitro/ex vivo use, while novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis. These preclinical studies show that these technologies can successfully edit genes and provide therapeutic benefits, including amyloid reduction and cognitive improvement in AD models. Yet off-target effects, immune responses and regulatory hurdles persist. Overall, continuous innovation in delivery vector design and safety profile-targeting strategies is crucial for advancing CRISPR-Cas9 towards clinical therapies for AD-based therapies and related neurological disorders.\n\nID: 41996987\nTitle: Decoding RNA splicing pathology: Alternative splicing in amyotrophic lateral sclerosis and its therapeutic potential.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder marked by progressive motor neuron loss, leading to muscle weakness, paralysis, and respiratory failure. Dysregulation of RNA metabolism and splicing has emerged as a central mechanism in ALS pathogenesis. TARDBP (TAR DNA-binding protein), FET family proteins (FUS, EWSR1, TAF15), SOD1 (Superoxide Dismutase 1), and C9orf72 (Chromosome 9 Open Reading Frame 72) are key genes associated with ALS that regulate RNA processing, alternative splicing, and nuclear-cytoplasmic transport. Mutations or mislocalization of these proteins result in nuclear loss-of-function and cytoplasmic gain-of-function toxicity, promoting protein aggregation, sequestering spliceosomal components, and impairing spliceosome assembly. This leads to the aberrant inclusion of cryptic exons in essential neuronal genes, such as STMN2 (Stathmin 2) and UNC13A (Unc-13 Homolog A), resulting in the production of truncated proteins, defective axonal maintenance, and impaired synaptic function. TDP-43 pathology, a hallmark of ALS, disrupts splicing and RNA transport, while C9orf72 repeat expansions and FET protein mutations exacerbate cytoplasmic aggregation and stress granule dynamics. Mutant SOD1 contributes via mitochondrial dysfunction, endoplasmic reticulum stress, and disrupted axonal transport. Therapeutic strategies targeting these mechanisms are advancing rapidly. Gene replacement therapy, which restores STMN2 expression, and antisense oligonucleotides (ASOs) targeting mutant transcripts show promise in preclinical and early clinical studies. Complementary approaches, including the inhibition of stress kinases and the activation of autophagy, reduce cytoplasmic protein aggregation and support neuronal homeostasis. This review provides a comprehensive overview of RNA splicing regulation, spliceosomal dysfunction, and cryptic exon incorporation in ALS. Understanding the interplay among splicing defects, RNA-binding protein pathology, and neuronal degeneration is critical for developing next-generation multimodal therapies to restore RNA processing, reduce toxic protein accumulation, and promote motor neuron survival.\n\nID: 41983529\nTitle: TDP43 and hnRNP K Regulate Alternative Splicing of DNAJC5.\nAbstract: Alternative splicing is a finely regulated process which defines the final maturation of pre-mRNAs. Modulation of trans-acting spliceosome proteins changes specific patterns of splicing and contributes to the development of diseases. During Amyotrophic Lateral Sclerosis (ALS) disease progression, loss of nuclear trans-acting splicing protein TDP43 leads to accumulation of cryptic exons in mRNAs, which inhibits expression of proteins and aggravates the disease. One of the affected genes is DNAJC5, which codes for a protein responsible for clearance of misfolded proteins in the cytoplasm. We first observed that TDP43 knockdown regulates DNAJC5 transcript splicing. A similar phenotype was observed upon hnRNP K knockdown. We hypothesized canonical splicing of DNAJC5 is dependent on the activity of both TDP43 and hnRNP K. Our results confirmed TDP43 and hnRNP K interaction is dependent on RNA. We also confirmed that DNAJC5 canonical splicing is dependent on its internal TDP43 and hnRNP K binding sites. Taken together, our work enrolls both TDP43 and hnRNP K on splicing regulation of DNAJC5 transcript, affecting activity of the protein encoded by DNAJC5 on endosomal traffic. As a result, activity of both TDP43 and hnRNP K and their association are important for ALS progression.\n\nID: 41845971\nTitle: The role of TDP-43 fragments in regular cellular functions and homeostatic failure.\nAbstract: Amyotrophic lateral sclerosis (ALS) is characterized by the progressive degeneration of motor neurons, leading to severe muscle weakness, loss of voluntary movement, and respiratory failure. A widely noted feature of the disease is the presence of TDP-43 proteinopathies. Under homeostatic conditions, the RNA/DNA-binding protein TDP-43 mainly resides in the nucleus, where it functions to regulate gene expression, controlling not only RNA transcription and splicing, but also stability and transport to the cytoplasm. Upon the arrival at ribosomes, TDP-43 may further moderate translation, acting as a global repressor of protein synthesis. However, in over 95% of ALS cases, TDP-43 mislocalises from the nucleus to the cytoplasm, where it enriches in cytoplasmic inclusions that are marked by the presence of misfolded, ubiquitinated, phosphorylated and fragmented protein species of TDP-43. Although recent studies have tried to untangle the relationship between TDP fragments on the one hand, and cytotoxicity as well as neurodegeneration on the other, the results are still a matter of debate. Here, we review our current understanding of the different TDP fragments derived from proteolytic cleavage as well as alternative splicing, addressing the different N-terminal and C-terminal species and evaluating differences in rodent and primate models. We focus our analysis on potential homeostatic functions of TDP fragments in the context of viral infections and myelination control, which could be pivotally interconnected. The findings illustrate several facets of fragmented TDP-43 protein species in scenarios of enhanced cellular stress. Gaining a detailed understanding could help to reveal new treatment options for ALS and other TDP-43 proteinopathies.\n\nID: 41837283\nTitle: Splicing the narrative: alternative TARDBP splicing and its relation to neurodegeneration in ALS and FTD.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are progressive neurodegenerative diseases characterized by the nuclear clearance and cytoplasmic aggregation of transactive response DNA/RNA-binding protein of 43 kDa (TDP43). Alternative splicing of TARDBP, the gene encoding TDP43, leads to a surprising diversity of RNA and protein isoforms with unique functions and potential implications for disease pathogenesis. Here, we review the production, properties, and functional consequences of alternative splicing in the development of ALS and FTD, focusing primarily on TDP43 due to its integral connection with the pathogenesis of sporadic as well as familial forms of these diseases. We synthesize current evidence on the biology of alternative TARDBP splicing, highlight key questions regarding its role in TDP43 proteinopathies such as ALS and FTD, and touch on the larger phenomenon of alternative splicing and its relationship to disease.\n\nID: 41812941\nTitle: CRISPR-based correction of apolipoprotein E4 in Alzheimer's disease: Therapeutic strategies and macromolecular delivery innovations.\nAbstract: Alzheimer's disease (AD) is the leading cause of dementia worldwide, with substantial unmet clinical needs. The apolipoprotein E4 (APOE4) allele is the strongest genetic risk factor for late onset AD, with each copy increasing risk approximately two- to three-fold, and homozygous carriers facing up to a 10- to 15-fold higher risk compared to APOE3 carriers. APOE4 contributes to diverse pathogenic mechanisms including lipid dysregulation, neuroinflammation, synaptic dysfunction, and vascular compromise. The precise, allele-specific correction of APOE4 therefore holds transformative therapeutic potential. CRISPR-based genome editing technologies, including nuclease disruption, base editing, and prime editing, offer unprecedented opportunities to directly modify APOE4 at its genomic source. Here, we review mechanistic underpinnings of APOE4 pathology, summarize current gene editing platforms for APOE4 correction, evaluate relevant in vitro and in vivo model systems, and assess delivery strategies with an emphasis on nanoparticle and exosome based approaches. We highlight recent breakthroughs in exosome mediated APOE4 editing while addressing ongoing technical hurdles in allele specificity and translational barriers such as Cas nuclease immunogenicity, limited delivery efficiency across the blood brain barrier (BBB), and concerns over long term genomic safety. This review concludes that overcoming BBB constraints remains the most significant challenge for clinical translation, and that innovations in exosome and nanoparticle based delivery platforms represent the most promising strategies for advancing CRISPR therapeutics for AD.\n\nID: 41720774\nTitle: A neurotoxic cryptic peptide arising from TDP-43-dependent cryptic splicing of PKN1.\nAbstract: Dysfunction of transactive response DNA-binding protein 43 (TDP-43) drives neurodegeneration in amyotrophic lateral sclerosis (ALS) and Alzheimer's disease (AD), in part through inducing aberrant RNA splicing. However, whether such mis-splicing yields stable, pathogenic proteins remains unclear. Here, we identify a TDP-43-repressed cryptic exon in Protein kinase N1 (PKN1), designated PKN1-5a1, which is activated in ALS patient brains and introduces a premature termination codon. This aberrant transcript escapes nonsense-mediated decay and is translated into a truncated peptide, PKN1-N207 (PKN207), detectable in AD brains with TDP-43 pathology. In mice, PKN207 impairs cognition, memory, and synaptic plasticity. Our findings demonstrate that TDP-43 loss-induced cryptic splicing can generate stable neurotoxic polypeptides, revealing a peptide-mediated mechanism in TDP-43 proteinopathies.\n\nID: 41670012\nTitle: The application of CRISPR-Cas9 system in brain diseases.\nAbstract: As an efficient genome-editing technology, Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)-CRISPR-associated protein9 (Cas9) system is increasingly being recognized as a significant therapeutic strategy for brain diseases. In recent years, researchers have continuously tried to regulate the expression of genes related to the nervous system through CRISPR-Cas9 system, which provides a new and efficient strategy for the treatment of brain diseases. At the same time, various delivery vectors of CRISPR-Cas9 system have been reported. Although some delivery vectors have not been applied to the research of brain diseases, they still provide valuable ideas for the brain delivery of CRISPR-Cas9 system. In this review, we summarized the principle of CRISPR-Cas9 system and its application in the nervous system, discussed the barrier of blood-brain barrier (BBB) to the treatment of brain diseases, overviewed various delivery vectors of CRISPR-Cas9 system and their applications, and highlighted advanced of CRISPR-Cas9 system applied to various brain diseases. Furthermore, we also discussed the existing obstacles and promising avenues for future investigation regarding CRISPR-Cas9-based therapeutic approaches. This article, through retrieving keyword combinations[PubMed,from Jan. 2018 to Dec. 2025], aims to elucidate the CRISPR-Cas9 system's potential for extensive future research and application as a therapeutic strategy for brain disorders.\n\nID: 41568513\nTitle: CRISPR in Alzheimer's Disease: Engineering Genetic Solutions for Neurodegenerative Resilience.\nAbstract: Alzheimer's Disease (AD), the primary etiology of dementia, remains a considerable challenge owing to the limited availability of pharmacological interventions that effectively modify the course of the disease. This review evaluates CRISPR/Cas9 gene editing as a therapeutic strategy for AD, focusing on its capacity to target genetic drivers (e.g., APP, APOE, PSEN1/2, CD2AP) and modify disease pathology. CRISPR offers unprecedented precision in disrupting AD-associated pathogenic alleles, addressing the limitations of conventional A\u03b2/tau-targeted therapies that have failed in clinical trials. CRISPR corrects mutations in iPSC/organoid models, normalizing A\u03b242/40 ratios and reducing tau hyperphosphorylation. Preclinical studies demonstrate reversal of amyloid accumulation and synaptic degeneration. Key challenges include off-target effects, blood-brain barrier (BBB) delivery limitations, and ethical concerns around permanent genome modifications. This study emphasizes that CRISPR/Cas9 holds transformative potential for AD therapy by targeting root genetic causes. Future success hinges on enhancing delivery systems (e.g., BBB-penetrant vectors) and integrating next-generation editors (base/prime editing) for clinical translation.\n\nID: 41386334\nTitle: Elucidating the roles of TM7SF3 and LHFPL6 in the putative H+/OC antiporter function in the human brain capillary endothelial cell line, hCMEC/D3.\nAbstract: The putative proton/organic cation (H+/OC) antiporter has been shown to mediate transport of CNS drug compounds like oxycodone and pyrilamine across the blood-brain barrier (BBB). This transporter has a broad substrate profile and is able to transport substrates against their concentration gradient, making it an interesting target for brain drug delivery. However, the molecular identity of this transporter remains unknown. Recent studies have indicated that the two proteins TM7SF3 and LHFPL6 might be components of this transporter. The present study aimed to investigate the roles of TM7SF3 and LHFPL6 in the H+/OC antiporter function to advance understanding of its molecular identity and potential in CNS drug delivery. CRISPR-Cas9 gene-editing was used to generate three hCMEC/D3 knockout (KO) cell lines: TM7SF3 KO (TM-KO), LHFPL6 KO (LH-KO), and a double KO of TM7SF3 and LHFPL6 (TMLH-KO). The uptake of pyrilamine analogue (EDMPG) and [3H]-pyrilamine was assessed in wild type (WT) and KO lines. Quantitative Realtime Polymerase Chain Reaction (qRT-PCR) confirmed successful gene knockouts. Passive diffusion properties and the expression and functionality of known BBB transporters, including LAT1 (SLC7A5), GLUT1 (SLC2A1), and MCT1 (SLC16A1), were also examined. The EDMPG uptake was significantly reduced in TM-, LH-, and TMLH-KO cells, suggesting that TM7SF3 and LHFPL6 contribute to the H+/OC antiporter function. However, [3H]-pyrilamine uptake remained unchanged across all KOs, indicating a TM7SF3- and LHFPL6-independent transport mechanism. This was further supported by the persistent inhibition of [3H]-pyrilamine uptake in the presence of known H+/OC antiporter substrates. While passive diffusion and GLUT1- and MCT1-mediated transport were unaffected, LAT1-mediated uptake of [3H]L-leucine and gabapentin (Neurontin) was significantly reduced in LH- and TMLH-KO cells, correlating with decreased LAT1 mRNA expression in these cells. This study suggests that the H+/OC antiporter operates via two distinct mechanisms: a high-capacity, TM7SF3- and LHFPL6-independent pathway and a low-capacity, TM7SF3- and LHFPL6-dependent pathway. These findings underscore the complexity of the H+/OC antiporter molecular composition and highlight the need for further research to fully elucidate its identity.\n\nID: 41174170\nTitle: TDP-43-dependent mis-splicing of KCNQ2 triggers intrinsic neuronal hyperexcitability in ALS/FTD.\nAbstract: Motor neuron hyperexcitability is a broadly observed yet poorly understood feature of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Nuclear depletion and cytoplasmic aggregation of the RNA splicing protein TAR DNA-binding protein 43 (TDP-43) are observed in most ALS and FTD patients. Here we show that TDP-43 dysfunction causes mis-splicing of KCNQ2, which encodes a voltage-gated potassium channel (Kv7.2) that regulates neuronal excitability. Using iPSC-derived neurons and postmortem ALS/FTD brain and spinal cord tissue we find widespread, disease-specific and TDP-43-specific skipping of an exon encoding the KCNQ2 pore domain. The mis-spliced mRNA escapes degradation and is translated into a nonfunctional protein with severely reduced ion conductance that aggregates in the endoplasmic reticulum and causes intrinsic hyperexcitability in ALS neuronal models. This event, which correlates with higher phosphorylated TDP-43 levels and earlier age of disease onset in patients, can be rescued by splice-modulating antisense oligonucleotides that dampen hyperexcitability in induced pluripotent stem cell cortical neurons and spinal motor neurons with TDP-43 depletion. Our work reveals that nuclear TDP-43 maintains the fidelity of KCNQ2 expression and function and provides a mechanistic link between established excitability disruption in ALS/FTD patients and TDP-43 dysfunction.\n\nID: 41043426\nTitle: Integrated profiling of iPSC-derived motor neurons carrying C9orf72, FUS, TARDBP, or SOD1 mutations.\nAbstract: Here, we conducted temporal RNA sequencing (RNA-seq) profiling of human induced pluripotent stem cells (hiPSCs) and induced pluripotent stem cell (iPSC)-derived motor neurons (iMNs) carrying C9orf72, FUS, TARDBP, or SOD1 mutations in both patients with amyotrophic lateral sclerosis (ALS) and healthy individuals. We discovered dysregulated gene expression and alternative splicing (AS) throughout iMN development and maturation, and iMNs with mutations in ALS-associated genes displayed enrichment of cytoskeletal defects and synaptic alterations from the premature stage to mature iMNs. Our findings indicate that synaptic gene dysfunction is a common molecular hallmark of familial ALS, which may result in neuronal susceptibility and progressive motor neuron degeneration. Analysis of upstream splicing factors revealed that differentially expressed RNA-binding proteins (RBPs) in iMNs from patients with ALS may cause abnormal AS events. Overall, our research provides a comprehensive and valuable resource for gaining insights into the shared mechanisms of familial ALS pathogenesis during motor neuron development and maturation in iMN models.\n\nID: 40778857\nTitle: Dominant-negative isoform of TDP-43 is regulated by ALS-linked RNA-binding proteins.\nAbstract: TDP-43, an RNA-binding protein (RBP) encoded by the TARDBP gene, is crucial for understanding the pathogenesis of neurodegenerative diseases like amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration. Dysregulated TDP-43 causes motor neuron loss, highlighting the need for proper expression levels. Here, we identify a dominant-negative isoform among the multiple TARDBP splicing variants and validate its endogenous expression using a developed antibody against its translated product. Furthermore, we revealed that ALS-associated RBPs regulate its expression: hnRNP K promotes its splicing and expression, while hnRNP A1 and FUS suppress these processes through distinct mechanisms. hnRNP A1 inhibits hnRNP K-mediated splicing, and FUS represses the dominant-negative isoform through both its translational inhibition and hnRNP K suppression. Notably, ALS-mutant FUS weakens this regulatory mechanism, leading to impaired repression of hnRNP K and the dominant-negative isoform. Our findings suggest a regulatory network involving ALS-linked RBPs that govern TDP-43 isoform expression and provide new insights into how disruptions in this network contribute to ALS pathogenesis.\n\nID: 40670663\nTitle: Long-read RNA sequencing unveils a novel cryptic exon in MNAT1 along with its full-length transcript structure in TDP-43 proteinopathy.\nAbstract: Understanding the role of transcript isoforms is essential for elucidating disease mechanisms. TDP-43 regulates RNA splicing, and its dysfunction in neurons is a hallmark of some neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal degeneration (FTD). While an association between TDP-43-dependent cryptic exons and disease pathogenesis has been suggested, an approach to investigate how cryptic exons disrupt transcript isoforms has yet to be established. In this study, we developed IsoRefiner, a novel method for identifying full-length transcript structures using long-read RNA-seq. Leveraging this method, we performed long-read RNA-seq, guided by prior short-read RNA-seq, to comprehensively determine the full-length structures of aberrant transcripts due to TDP-43 dysregulation in human iPSC-derived motor neurons. We identified a novel TDP-43-dependent cryptic exon in the MNAT1 gene, along with its full-length transcript structure. Furthermore, we confirmed the presence of the MNAT1 cryptic exon in patients with ALS and FTD. Our findings deepen understanding of TDP-43 proteinopathy and advance splicing research.\n\nID: 40665471\nTitle: Focused ultrasound-mediated APOE4 knockdown in mouse brain.\nAbstract: The apolipoprotein E (APOE) \u03b54 allele is widely recognized as the strongest genetic risk factor for late-onset Alzheimer's disease. Therapeutic strategies to reduce apoE4 expression in APOE \u03b54 carriers hold promise to mitigate neuroinflammatory and neurodegenerative processes driving disease progression. Focused ultrasound (FUS) was employed to transiently open the blood-brain barrier (BBB) for efficient knockdown of humanized APOE \u03b54 in the mouse brain via gene editing. The all-in-one clustered regularly interspaced short palindromic repeats (CRISPR)-based adeno-associated virus (AAV) vectors were administered intravenously at a dose of 1.5\u00d71012 vg per mouse to determine the gene-editing efficacy within the hippocampus. FUS-enhanced delivery of AAV resulted in a 12.6% knockdown of APOE \u03b54 gene expression in the targeted hippocampus, accompanied by an over 20% decrease in apoE4 protein levels and significant reductions in astrocyte and microglia levels. Our findings demonstrate a noninvasive, targeted approach for APOE \u03b54 knockdown, highlighting FUS-mediated brain-directed interventions as a promising therapeutic strategy for Alzheimer's disease. Focused ultrasound (FUS) enables noninvasive, transient blood-brain barrier (BBB) opening for enhanced adeno-associated virus (AAV) delivery. FUS-mediated gene editing achieves a 12.6% knockdown in APOE \u03b54 expression within the hippocampus of mouse brain. APOE \u03b54 knockdown significantly reduces apoE4 protein levels and astrocyte and microglia levels. No detectable gross toxicity was observed following the FUS-mediated gene editing.\n\nID: 40603049\nTitle: [Elucidation of the Molecular Mechanism Underlying Aberrant Formation of RNA Granules in Neurons of ALS Patients and Its Regulation].\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal motor neuron disease characterized by progressive muscle atrophy throughout the body. In nearly all ALS patients, abnormal accumulation of the RNA-binding protein TDP-43 is observed in degenerating motor neurons. We have found that RNA-binding proteins such as TDP-43 and FUS are concentrated in GEM bodies, where they contribute to the integrity of the spliceosome machinery involved in pre-RNA splicing. Additionally, the most common cause of ALS, repeat expansion in the C9orf72 gene, triggers abnormal repeat-associated non-AUG (RAN) translation, leading to the accumulation of neurotoxic dipeptide repeat (DPR) proteins. We have identified that these DPR proteins may inhibit GEM body formation and contribute to ALS pathology. Furthermore, therapeutic approaches to suppress RAN translation using dCas13 technology are under development, offering promising new strategies to address abnormalities in RNA metabolism in ALS.\n\nID: 40583130\nTitle: Cryptic Splicing of GAP43 mRNA is a Novel Hallmark of TDP-43-Associated ALS and AD.\nAbstract: Cytoplasmic aggregation of transactive response DNA-binding protein 43 (TDP-43) is a hallmark of amyotrophic lateral sclerosis (ALS) and occurs in 57% of Alzheimer's disease (AD) cases. TDP-43 regulates RNA processing, including cryptic exon splicing. Here, we demonstrate that TDP-43 directly controls growth-associated protein (GAP43) expression by binding to its pre-mRNA. Loss or hyperphosphorylation of TDP-43 disrupts this binding, leading to the inclusion of cryptic exon 4a1, which introduces premature stop codons and reduces GAP43 protein levels. RNA sequencing analysis of ALS and AD brains revealed GAP43 downregulation, while 4a1 is upregulated in AD cases with phosphorylated TDP-43. TDP-43 knockdown impaired axonal regeneration in induced pluripotent stem cell (iPSC)-derived motor neurons, whereas GAP43 restoration rescued this defect. These findings suggest that the loss of GAP43 contributes to neurodegeneration in ALS and AD. The inclusion of GAP43 cryptic exon 4a1 may serve as a hallmark of TDP-43 proteinopathies,\u00a0highlighting a mechanistic link between TDP-43 dysfunction and neuronal vulnerability.\n\nID: 40518022\nTitle: Synergistic pathways in Parkinson's disease: The promise of FGF21 and ACE2.\nAbstract: Parkinson's disease (PD), the second most prevalent neurodegenerative disorder globally, is pathologically characterized by progressive degeneration of dopaminergic neurons in the substantia nigra (SN). Current therapeutic strategies primarily alleviate clinical symptoms but lack efficacy in halting or reversing neurodegeneration. Recent studies have highlighted the FGF21-ACE2 signaling axis-a synergistic interaction between fibroblast growth factor 21 (FGF21) and angiotensin-converting enzyme 2 (ACE2)-as an emerging therapeutic target in PD due to its tripartite roles in neuroprotection, anti-inflammatory modulation, and metabolic homeostasis. Mechanistically, FGF21 activates neuroprotective pathways including phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) and the extracellular signal-regulated kinase (ERK)1/2, suppressing apoptotic cascades, amplifying antioxidant defenses, and stimulating dopaminergic neuron differentiation. Conversely, ACE2 counterbalances neurotoxicity by converting angiotensin II (Ang II) to angiotensin-(1-7) [Ang-(1-7)], thereby mitigating neuroinflammation and oxidative stress. Their coordinated activity potently inhibits M1 microglial activation, downregulates pro-inflammatory cytokines (e.g., TNF-\u03b1), and bolsters astrocytic antioxidant responses while preserving metabolic equilibrium. Notably, this axis ameliorates mitochondrial dysfunction and attenuates \u03b1-synuclein (\u03b1-syn) aggregationvia modulation of mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-\u03baB) signaling networks, collectively decelerating PD pathogenesis. Therapeutic interventions such as small-molecule agonists (e.g., diminazene aceturate, DIZE) and CRISPR-Cas9-mediated gene editing show potential to upregulate FGF21-ACE2 activity, while non-pharmacological approaches including exercise and ketogenic diets may synergistically enhance pathway efficacy. However, translational hurdles persist, including limited blood-brain barrier (BBB) permeability of therapeutics, off-target effects, and insufficient clinical validation. Future directions should prioritize deciphering dynamic molecular crosstalk within this pathway, engineering BBB-penetrant nanocarriers for targeted delivery, and conducting large-scale randomized controlled trials. This review underscores the FGF21-ACE2 axis as a multi-mechanistic therapeutic paradigm for PD, with its capacity for simultaneous modulation of neurodegeneration, inflammation, and metabolism positioning it as a superior candidate to conventional single-target therapies in achieving disease modification.\n\nID: 40285014\nTitle: Neuroinflammation, Blood-Brain Barrier, and HIV Reservoirs in the CNS: An In-Depth Exploration of Latency Mechanisms and Emerging Therapeutic Strategies.\nAbstract: Despite the success of antiretroviral therapy (ART) in suppressing viral replication in the blood, HIV persists in the central nervous system (CNS) and causes chronic neurocognitive impairment, a hallmark of HIV-associated neurocognitive disorders (HAND). This review looks at the complex interactions among HIV, the blood-brain barrier (BBB), neuroinflammation, and the roles of viral proteins, immune cell trafficking, and pro-inflammatory mediators in establishing and maintaining latent viral reservoirs in the CNS, particularly microglia and astrocytes. Key findings show disruption of the BBB, monocyte infiltration, and activation of CNS-resident cells by HIV proteins like Tat and gp120, contributing to the neuroinflammatory environment and neuronal damage. Advances in epigenetic regulation of latency have identified targets like histone modifications and DNA methylation, and new therapeutic strategies like latency-reversing agents (LRAs), gene editing (CRISPR/Cas9), and nanoparticle-based drug delivery also offer hope. While we have made significant progress in understanding the molecular basis of HIV persistence in the CNS, overcoming the challenges of BBB penetration and neuroinflammation is key to developing effective therapies. Further research into combination therapies and novel drug delivery systems will help improve outcomes for HAND patients and bring us closer to a functional cure for HIV.\n\nID: 39987392\nTitle: The Regulation of TDP-43 Structure and Phase Transitions: A Review.\nAbstract: The transactive response DNA binding protein 43 (TDP-43) is an RNA/DNA-binding protein that is involved in a number of cellular functions, including RNA processing and alternative splicing, RNA transport and translation, and stress granule assembly. It has attracted significant attention for being the primary component of cytoplasmic inclusions in patients with amyotrophic lateral sclerosis or frontotemporal dementia. Mounting evidence suggests that both cytoplasmic aggregation of TDP-43 and loss of nuclear TDP-43 function contribute to TDP-43 pathology. Furthermore, recent studies have demonstrated that TDP-43 is an important component of many constitutive or stress-induced biomolecular condensates. Dysregulation or liquid-to-gel transition of TDP-43 condensates can lead to alterations in TDP-43 function and the formation of TDP-43 amyloid fibrils. In this review, we summarize recent research progress on the structural characterization of TDP-43 and the TDP-43 phase transition. In particular, the roles that disease-associated genetic mutations, post-translational modifications, and extrinsic stressors play in the transitions among TDP-43 monomers, liquid condensates, solid condensates, and fibrils are discussed. Finally, we discuss the effectiveness of available regulators of TDP-43 phase separation and aggregation. Understanding the underlying mechanisms that drive the pathological transformation of TDP-43 could help develop therapeutic strategies for TDP-43 pathology.\n\nID: 39797776\nTitle: Cascade-Responsive Nanoparticles for Efficient CRISPR/Cas9-Based Glioblastoma Gene Therapy.\nAbstract: CRISPR/Cas9 (CRISPR, clustered regularly interspaced short palindromic repeats) gene editing technology represents great promise for treating glioblastoma (GBM) due to its potential to permanently eliminate tumor pathogenic genes. Unfortunately, delivering CRISPR to the GBM in a safe and effective manner is challenging. Herein, a glycosylated and cascade-responsive nanoparticle (GCNP) that can effectively cross the blood-brain barrier (BBB) and activate CRISPR/Cas9-based gene editing only in the GBM is designed. The GCNP possesses a cationic polyplex core and a glycosylated polymer layer that is capable of cascading response to low pH and high GSH concentration, so that the release of CRISPR/Cas9 only takes place after crossing the BBB and entering the GBM where the acidic tumor microenvironment and high concentration of glutathione (GSH) are present. By targeting the programmed death-ligand 1 (PD-L1) in GBM, GCNP effectively inhibited the tumor growth and greatly prolonged the survival time of GBM-bearing mice when combined with temozolomide (TMZ).\n\nID: 39486415\nTitle: Inhibition of RNA splicing triggers CHMP7 nuclear entry, impacting TDP-43 function and leading to the onset of ALS cellular phenotypes.\nAbstract: Amyotrophic lateral sclerosis (ALS) is linked to the reduction of certain nucleoporins in neurons. Increased nuclear localization of charged multivesicular body protein 7 (CHMP7), a protein involved in nuclear pore surveillance, has been identified as a key factor damaging nuclear pores and disrupting transport. Using CRISPR-based microRaft, followed by gRNA identification (CRaft-ID), we discovered 55 RNA-binding proteins (RBPs) that influence CHMP7 localization, including SmD1, a survival of motor neuron (SMN) complex component. Immunoprecipitation-mass spectrometry (IP-MS) and enhanced crosslinking and immunoprecipitation (CLIP) analyses revealed CHMP7's interactions with SmD1, small nuclear RNAs, and splicing factor mRNAs in motor neurons (MNs). ALS induced pluripotent stem cell (iPSC)-MNs show reduced SmD1 expression, and inhibiting SmD1/SMN complex increased CHMP7 nuclear localization. Crucially, overexpressing SmD1 in ALS iPSC-MNs restored CHMP7's cytoplasmic localization and corrected STMN2 splicing. Our findings suggest that early ALS pathogenesis is driven by SMN complex dysregulation.\n\nID: 42418462\nTitle: Transcriptomic and Proteomic Insights Into Diapause in the Wheat Stink Bug, Aelia rostrata.\nAbstract: The wheat stink bug, Aelia rostrata (Hemiptera: Pentatomidae), is a major pest of wheat in Central Anatolia. This species has an extended adult dormancy period lasting approximately 9 months. This period encompasses summer estivation and winter diapause in mountainous dormancy areas. Despite its economic importance and unusual dormancy biology, the molecular basis of seasonal dormancy in A. rostrata remains unexplored. Here, we combined RNA-seq, proteomics, and lipid content measurements to provide the first molecular insights into estivation and winter diapause responses in the fat body of the wheat stink bug. Transcriptomic enrichment analyses suggested that genes associated with protein synthesis, cytoplasmic translation, and ribosomal activity were enriched during estivation, whereas pathways related to catabolic processes, fatty acid metabolism, and pathogen response were associated with winter diapause. Complementary proteomic analyses identified mitochondrial and chitinase-like proteins with higher abundance during estivation, while proteins related to energy metabolism, including acyl-CoA dehydrogenases, were more abundant during winter diapause. Lipid measurements indicated significantly lower lipid reserves in post-diapause individuals compared to actively feeding adults, consistent with the utilization of lipid stores during dormancy and/or the transition to post-dormancy activity. Overall, this study provides the first transcriptomic and proteomic resource for A. rostrata and offers initial molecular insights into the physiological signatures associated with seasonal dormancy in this economically important pest.\n\nID: 42418414\nTitle: Bioinformatics analysis reveals the characteristics of immune microenvironment in major depressive disorder and vitiligo.\nAbstract: Major depressive disorder (MDD) and vitiligo often occur together, worsening patient outcomes. However, the shared pathogenic mechanisms remain unclear. This study applied integrated bioinformatics to identify shared candidate markers for MDD and vitiligo. Public transcriptomic datasets from the GEO database were analyzed for differential expression. Protein-protein interaction (PPI) networks were constructed using the STRING database. Shared differentially expressed genes (DEGs) underwent GO and KEGG functional enrichment analyses. Three machine-learning algorithms were applied to select candidate biomarker genes. Additionally, immune infiltration analysis was quantified through ssGSEA and a TF-miRNA network was constructed via NetworkAnalyst platform. Single-gene GSEA further explored pathways linked to the biomarker in both diseases. Differential expression analysis and PPI network construction suggest the involvement of 14 hub genes potentially linked to both MDD and vitiligo. Functional enrichment analyses indicate their putative roles in immune processes and inflammatory responses. Machine learning further prioritized three key genes: EXOSC7, KLRG1, and MAPK14. Immune infiltration analysis revealed distinct patterns of inferred immune enrichment signatures, and the TF-miRNA network highlighted the complexity of the regulatory landscape. Preliminary validation suggests MAPK14 as a potential candidate gene warranting further investigation in MDD and vitiligo. This study provides preliminary evidence suggesting that immune dysregulation and inflammatory activation may be interconnected in MDD and vitiligo. MAPK14 represents a potential candidate marker for their comorbidity. These findings primarily serve to generate hypotheses regarding shared mechanisms and prioritize targets for subsequent experimental validation.\n\nID: 42418076\nTitle: Integrative functional genomics maps synaptic and developmental-regulatory autism risk-gene sets across human cortex.\nAbstract: Autism spectrum disorder (ASD) risk genes converge on synaptic and developmental regulatory biology, but it remains unclear whether fixed risk-gene sets retain the same functional meaning across prenatal and adult cortical contexts. We analyzed predefined ASD risk-gene sets across BrainSpan developmental transcriptomics, three adult cortical bulk cohorts, fetal and adult single-cell resources, composition-aware bulk models, SynGO and Reactome annotations, matched-random controls, correlation-aware gene-set tests, and STRING physical-interaction networks. The broad SFARI gene set showed the strongest adult cortex ASD-control meta-analytic reduction, driven mainly by its SynGO-annotated synaptic component. This adult signal remained significant in Gandal2022 after donor-aware modeling, donor-level aggregation, mixed-effects modeling, covariate sensitivity analyses, outlier checks, and drop-one-reference composition adjustment. Size-matched gene-level resampling indicated that the signal was not explained by gene-set size alone, whereas expression-matched controls supported a more conservative interpretation involving expression-level background properties. In contrast, the mid-prenatal top-20% SFARI subset localized more strongly to fetal progenitor-to-neurogenic states and chromatin-regulatory Reactome terms but did not show a stable adult cortical ASD-control effect. These results define an adult synaptic ASD-associated layer and a mid-prenatal developmental-regulatory layer within predefined ASD risk-gene sets.\n\nID: 42418003\nTitle: Rhizome differentiation is associated with metabolic specialization and rhizosphere microbial assembly in Rheum officinale Baill.\nAbstract: Distinct rhizome architectures are associated with differences in metabolic profiles and rhizosphere microbial composition within a single plant. Rhizome differentiation is a common developmental feature in perennial medicinal plants, yet its association with secondary metabolism and rhizosphere microbial assembly remains poorly understood. Here, we investigated the functional divergence between main rhizome (DH) and lateral rhizome (DC) of Rheum officinale Baill. using integrated metabolomic and transcriptomic analyses, quantitative real-time PCR (qRT-PCR) validation, and rhizosphere microbiome analyses. Metabolomic profiling revealed distinct patterns in anthraquinone allocation among rhizome types. DC exhibited a higher relative abundance of total detected anthraquinones and was enriched in both free anthraquinones (e.g., rhein) and selected glycosylated anthraquinones (e.g., chrysophanol 1-tetraglucoside), whereas DH preferentially accumulated other glycosylated metabolites such as cassiaside B2. Transcriptomic analysis identified 484 differentially expressed genes (DEGs) associated with these metabolic differences. Genes involved in anthraquinone biosynthesis and modification, including polyketide synthase (PKS), cytochrome P450 (CYP450), O-methyltransferase (OMT), and UDP-glycosyltransferase (UGT) family members, exhibited differential expression patterns associated with rhizome type, which were further validated by qRT-PCR. Although overall rhizosphere microbial diversity showed no significant differences between rhizome types, specific taxonomic shifts were observed, with Stenotrophomonas enriched in DC and Bacilli enriched in DH. Integrated analysis indicated correlation patterns among rhizome architecture, anthraquinone metabolism, transcriptional variation, and rhizosphere microbial composition. However, the directionality and underlying mechanisms of these relationships remain unresolved and warrant further mechanistic investigation. This study provides new insights into the biological basis of rhizome differentiation in Rheum officinale Baill.\n\nID: 42412825\nTitle: Riemannian metric learning for alignment of spatial multiomics.\nAbstract: Recent spatial technologies measure the transcriptome, epigenome, proteome, metabolome, and other modalities from thousands of cells across a tissue. Most assays typically profile only one modality from a tissue slice, raising the question of how to align spatial data from heterogeneous feature spaces. While multiple approaches have been developed for multi-modal integration of single-cell datasets, few existing techniques perform spatial alignment across arbitrary modalities incorporating both spatial and feature information. We introduce Manifold Gromov-Wasserstein (MGW), a metric-learning framework that exploits the product structure of spatial multiomics to infer modality-specific Riemannian pull-back metrics with neural fields. MGW aligns Riemannian distances induced by these metrics via Gromov-Wasserstein optimal transport, yielding a hyperparameter-free cost across arbitrary modalities sharing a spatial base. The formulation enjoys theoretical invariances-including orthogonal transformations of the spatial and feature domains as well as global feature scalings. We demonstrate the advantages of MGW on multiple alignment tasks, including Stereo-Seq spatiotemporal transcriptomics of mouse embryo, Xenium and Visium spatial transcriptomics of colorectal cancer, and spatial metabolomics-transcriptomics from human striatum and kidney cancer. MGW recovers biologically meaningful correspondences and spatially coherent tissue structures, outperforming existing OT and non-OT based multi-modal baselines. Software is available at https://github.com/raphael-group/MGW.\n\nID: 42412816\nTitle: Diffusion-based representation integration for foundation models improves spatial transcriptomics analysis.\nAbstract: We propose DRIFT, a framework that integrates spatial context into the input representations for foundation models by leveraging diffusion on spatial graphs derived from spatial transcriptomics (ST) data. ST captures gene expression profiles while preserving spatial context, enabling downstream analysis tasks such as cell-type annotation, clustering, and cross-sample alignment. However, due to its emerging nature, there are very few foundation models that can utilize ST data to generate embeddings generalizable across multiple tasks. Meanwhile, well-documented foundational models trained on large-scale single-cell gene expression (scRNA-seq) data have demonstrated generalizable performance across scRNA-seq assays, tissues, and tasks; however, they do not leverage the spatial information in ST data. We use heat kernel diffusion to propagate embeddings across spatial neighborhoods, incorporating the local neighborhood context of the ST data while preserving the transcriptomic representations learned by state-of-the-art single-cell foundation models. We systematically benchmark five foundational models (both scRNA-seq and ST-based) across key ST tasks such as annotation, alignment, and clustering, ensuring a comprehensive evaluation of our proposed framework. Our results show that DRIFT significantly improves the performance of existing foundational models on ST data over specialized state-of-the-art methods. Overall, DRIFT is an effective, accessible, and generalizable framework that bridges the gap toward universal models for modeling spatial transcriptomics. Code and data are available at https://github.com/rsinghlab/DRIFT.\n\nID: 42412833\nTitle: A disentangled transformer-based transfer learning framework to predict patient drug response from tumor single-cell transcriptomics.\nAbstract: Intratumoral cellular heterogeneity limits therapeutic efficacy in cancer patients. Although single-cell transcriptomics offers high-resolution profiling, translating these insights into clinical drug response prediction remains challenging. Recently, transfer learning approaches have attempted to predict patient drug response by leveraging pre-clinical data. However, these approaches operate at the bulk level, often masking the cellular heterogeneity essential for prediction. In this study, we propose scTAPE, a disentangled transfer learning framework to predict patient drug response using tumor single-cell transcriptomics. scTAPE follows a pre-training and fine-tuning paradigm. During the pre-training stage, scTAPE uses a disentangled learning strategy to extract intrinsic pharmacological signals masked by confounding factors from the matched bulk and single-cell expression profiles. Subsequently, a supervised drug response model is trained on labeled cell-line data to fine-tune the aligned common embedding, thereby achieving cross-domain generalization to unseen datasets. Experimental results demonstrate that scTAPE successfully predicts drug response across cell-line datasets and two independent clinical cohorts, outperforming state-of-the-art single-cell-based predictors. Furthermore, by analyzing tumor cell subpopulations, scTAPE not only predicts patient drug response to both single and combination treatments but also identifies potential therapeutic agents targeting drug-resistant subpopulations. The implementation of scTAPE is available via https://github.com/xinliangSun/scTAPE.\n\nID: 42412830\nTitle: A dependency-aware deep generative model for inferring RNA velocity from spatial transcriptomics.\nAbstract: The development of spatial transcriptomics enables transcriptome-wide profiling of cells within their tissue context, offering new opportunities to study spatially organized cellular state transitions. RNA velocity provides a powerful framework for inferring transcriptional dynamics from snapshot data, but most existing methods were designed for dissociated single-cell data and ignore spatial dependency. We present spaVelo, a dependency-aware deep generative model for RNA velocity inference from spatial transcriptomics data. spaVelo integrates spatial information into transcriptional kinetics using a spatial-aware variational autoencoder and a spatially modulated transcriptional scaling factor, enabling the modeling of spot-specific and heterogeneous dynamics. Across simulated and real datasets, spaVelo reconstructs biologically coherent velocity fields and developmental trajectories, outperforming existing methods, particularly in tissues with complex spatial organization. The source code of spaVelo is available at: https://github.com/1062638515/spaVelo.\n\nID: 42412818\nTitle: R4ST: a reference-guided graph-generative model for robust reconstruction of spatial transcriptomic profiles.\nAbstract: The trade-off between spatial granularity and transcriptome coverage in current spatial transcriptomics (ST) technologies results in sparse and incomplete expression profiles. Meanwhile, the rich local and global spatial topology inherent in spatial data are crucial for accurate biological interpretation but remain underutilized by existing methods. Here, we propose R4ST, an end-to-end framework designed to complete ST data. R4ST leverages scRNA-seq data as a reference and employs dual learning channels based on graph inductive and transductive modeling to capture complementary spatial topology information in ST data, enabling accurate reconstruction of missing gene expression. Extensive evaluations across multiple datasets from different platforms demonstrate that R4ST enables accurate recovery of large-scale gene expression profiles from a small subset of measured genes, uncovers novel spatial patterns associated with rare cell types, and substantially enhances the biological interpretability of ST data. https://github.com/zpliulab/R4ST.\n\nID: 42412805\nTitle: Amaranth: enhanced single-cell transcript assembly via discriminative modelling of UMI reads and internal reads.\nAbstract: Single-cell RNA sequencing (scRNA-seq) has transformed transcriptome profiling at cellular resolution, yet accurate reconstruction of full-length transcripts for individual cells remains a central challenge. Emerging scRNA-seq protocols can produce reads that span entire transcripts, enabling isoform-level expression analysis. For example, Smart-seq protocols combine unique molecular identifier (UMI)-linked reads that index and stitch together multiple reads from the same molecule, with internal reads filling coverage gaps. We demonstrate that these read types exhibit markedly different biological and statistical properties in strandness, 5'/3' coverage bias, and genomic locality. Existing assemblers fail to leverage these distinctions, yielding suboptimal assembly. We developed Amaranth, a novel single-cell assembler that discriminatively models UMI and internal reads. Amaranth implements heuristics specifically designed to address the distinct biases of UMI-linked and internal reads, enabling accurate strandness assignment for internal reads, reliable splicing graph refinement, and precise transcript start site determination. We also developed Amaranth-meta, which integrates information across cells to enhance individual cell assemblies. Benchmarked on Smart-seq3 datasets from human HEK293T and mouse fibroblast cells, Amaranth outperformed other state-of-the-art assemblers in assembling individual cells and in meta-assembly. Amaranth advances isoform-level analysis in single-cell transcriptomics, facilitating detailed studies at cellular resolution. Amaranth is implemented in C++ and is freely available at https://github.com/Shao-Group/amaranth under the BSD-3-Clause license. Scripts, documentation, and data for reproducing experiments in this manuscript are available at https://github.com/Shao-Group/amaranth-test.\n\nID: 42411821\nTitle: scImmuneCo: a compendium of cell-type-specific functional modules for decoding immune responses from single-cell RNA-seq data.\nAbstract: Traditional, knowledge-driven pathway annotations and bulk transcriptomic analyses often fail to capture the cellular specificity and mechanistic heterogeneity of immune responses. We present scImmuneCo, a comprehensive resource of immune cell-specific co-expression modules derived from single-cell RNA sequencing across 17 immunological conditions and 1.78 million cells. Using a modified graph-based framework, we constructed 873 robust modules spanning 7 major immune cell types, providing stable, cell-type-specific interaction networks for functional inference. scImmuneCo resolves complex biology at cellular resolution. We identify 20 interferon-related modules that reveal both conserved and cell-type-specific regulatory programs, clarifying disease-dependent differences that are invisible to pathway tools treating interferon signaling as a unitary process. We also uncover age-associated CD8+ T cell programs, capturing state transitions from naive to effector/memory cells and exposing a progressive imbalance in translation and cytotoxicity with age. Together, these results demonstrate the power of high-resolution, data-driven functional inference to link gene groups to biological roles and disease processes. To support broad application, we provide an R package (https://github.com/FrankQYW/scImmuneCo_R) for module-based analysis of both single-cell and bulk transcriptomic data, along with an interactive web portal (http://www.scimmuneco.site/) for visualization and gene-module exploration. scImmuneCo offers a scalable and interpretable framework for dissecting immune mechanisms and identifying disease-relevant transcriptional programs with cellular resolution.\n\nID: 42411190\nTitle: Multi-Omics Framework Integrating Genetics, Microbiome, Metabolism, and Immunity for Deciphering Ulcerative Colitis Pathogenesis and Diagnostic Biomarker Discovery.\nAbstract: Ulcerative colitis (UC) is an inflammatory bowel disease involving complex interactions between genetics, gut microbiota, metabolism, and immunity. This study aimed to systematically evaluate multi-omics factors potentially associated with UC susceptibility and identify reliable diagnostic biomarkers. A two-sample Mendelian randomization (MR) framework assessed potential causal associations between gut microbiome, circulating metabolites, immune cell phenotypes, and UC susceptibility. Significant MR findings were integrated with multiple transcriptomic datasets to identify differentially expressed candidate genes. Immune infiltration analysis, machine learning modeling, and external validation were subsequently performed. Single-cell and spatial transcriptomics were used to localize key genes and to explore their potential cell type-specific functions within the tissue microenvironment, followed by qRT-PCR validation in independent clinical tissues and siRNA-mediated IFITM2 knockdown in THP-1-derived macrophages. MR analyses identified potential causal associations for specific microbiota, sphingomyelin-related metabolites, and immune cell phenotypes with UC susceptibility. Integrative analysis prioritized four core signature genes: SAG, WDR48, IFITM2, and SIRPA. A random forest model achieved an AUC of 0.964 and identified a four-gene signature with strong diagnostic performance. Single-cell and spatial transcriptomics localized IFITM2 upregulation mainly to myeloid cells, particularly Neutrophil_IFITM2. CellChat suggested a potential CD4_Tem_IL7R-ANXA1-FPR1-Neutrophil_IFITM2 axis. qRT-PCR supported the expression directions of the four genes, and IFITM2 knockdown in THP-1-derived macrophages reduced TNF-\u03b1, IL-6, and IL-1\u03b2 mRNA expression. This multi-omics framework supports the potential roles of specific microbiota, sphingolipid metabolism, and immune phenotypes in UC pathogenesis. The four-gene signature and characterization of Neutrophil_IFITM2, supported by independent qRT-PCR validation and preliminary IFITM2 knockdown experiments, may provide a framework for precision diagnosis and future mechanistic studies in UC.\n\nID: 42409521\nTitle: RNA demethylase CsALKBH8 enhances postharvest disease resistance of citrus fruit against penicillium digitatum via m6A-mediated transcript regulation.\nAbstract: N6-methyladenosine (m6A) is a widespread internal modification of eukaryotic mRNA and is increasingly recognized as an important regulator of plant growth, development, and stress adaptation. However, its involvement in postharvest disease resistance of fruit is still poorly defined. In the present study, we identified an RNA demethylase, CsALKBH8, and investigated its function in citrus defense against green mold. We found that Penicillium digitatum infection significantly reduced global m6A levels in citrus peel, accompanied by rapid induction of CsALKBH8 expression. In vitro assays confirmed that CsALKBH8 possesses m6A demethylase activity. Transient overexpression of CsALKBH8 in citrus peel markedly alleviated disease development, as reflected by lower infection severity and smaller lesions after pathogen challenge. Transcriptome analysis revealed that CsALKBH8 overexpression induced extensive reprogramming of gene expression, with significant enrichment of defense-related pathways, including reactive oxygen species (ROS) metabolism, phenylpropanoid biosynthesis, and plant-pathogen interaction. Furthermore, CsALKBH8 reduced m6A levels on transcripts of multiple defense-related genes, including CsPR-1, CsPODs, CsRBOHF, CsGSTs, and lignin biosynthesis-associated genes, thereby enhancing their expression. This epitranscriptomic regulation promoted the activation of ROS metabolism and lignin accumulation, leading to increased enzyme activities (NOX, SOD, POD, APX, GST, and LAC) and elevated levels of H2O2, O\u2082-, and lignin, ultimately strengthening disease resistance in citrus fruit. Collectively, our findings demonstrate that CsALKBH8 enhances citrus resistance to P. digitatum through m6A-dependent post-transcriptional regulation of defense pathways, highlighting its potential as a molecular target for improving fruit storage quality and postharvest disease control.\n\nID: 42407121\nTitle: scGenoByte: a GenoByte embedding transformer with biological priors for cell type annotation.\nAbstract: Effective cell representation learning is crucial for accurate cell annotation and the deciphering of cellular heterogeneity in single-cell RNA sequencing (scRNA-seq) analysis. Current foundation models have achieved superior performance compared with traditional methods. However, due to data sparsity and the complexity of model, existing methods often compromise by selecting highly variable genes or filtering for nonzero expressions, which discard potentially significant genes. Thus, modeling the complete transcriptome for cell representation remains computationally challenging; we present scGenoByte, a unified framework designed to enhance cell representation learning through biologically informed full-gene modeling. To enable efficient modeling of the full transcriptome, we design GenoBytes, biologically coherent units that are constructed by leveraging biological priors in terms of protein-protein interaction network and gene paralogy network. Furthermore, considering that the information of protein and pathway is critical for analyzing cell functions and representation, scGenoByte encapsulates biological priors by harmonizing GenoByte embeddings with protein representations and leveraging an auxiliary task of pathway activity prediction to impose pathway-guided regularization. Extensive results on eight datasets have shown that scGenoByte achieves better performance than competing methods, which confirms the efficacy of combining full-gene context with biological priors.\n\nID: 42407120\nTitle: FerroScore: a statistical approach for quantifying tumor-related ferroptosis based on omics data.\nAbstract: Ferroptosis is a novel form of programmed cell death driven by iron-dependent lipid peroxidation, and can significantly influence the progression of complex diseases such as cancer. Current methods of detecting ferroptosis rely primarily on experimental techniques that are typically low-throughput and costly, limiting their clinical applications. Here we develop an effective statistical method, FerroScore, to quantify ferroptosis by generating a score that integrates the activities of three core pathways-iron, glutathione, and lipid metabolism. This method enables the cross-resolution assessment of ferroptosis and provides mechanistic insights into tumor, immune, and neurodegenerative diseases, thus having potential applications in targeted therapy and drug discovery. When applied to pancreatic cancer transcriptomic data, FerroScore reveals: (i) a U-shaped relationship between ferroptosis and patient survival; (ii) heterogeneous ferroptosis activity across cell types in the tumor microenvironment, with high sensitivity to Macrophages, CD8 Tcm cells, and a population of nCAFs; (iii) the role of ferroptosis-active cells in reshaping the immunosuppressive and pro-metastatic microenvironment through intercellular communication.\n\nID: 42405675\nTitle: Dual-Hit Myopia Mechanism Unveiled by Multi-Omics: Opn1mw Deficiency Primed the Retina for Exaggerated Response to Environmental Defocus.\nAbstract: Chromatic cues have long been implicated in refractive development, and OPN1MW variants are strongly associated with high myopia in humans. This study aimed to elucidate how cone opsin dysfunction translates into molecular and functional susceptibility to myopia. Retinal transcriptome and metabolome sequencing were performed in Opn1mw\u207b/\u207b (MKO), Opn1sw\u207b/\u207b (SKO), and wild-type (WT) mice. To assess susceptibility to lens-induced myopia (LIM), the right eyes of MKO and WT mice were fitted with -25 D lenses. In a rescue experiment, MKO mice were treated with the dopamine (DA) D1 receptor agonist SKF38393 hydrochloride. Refractive error, ocular biometry, and retinal DA levels were assessed. Retinas from WT mice and MKO mice with and without lens-wearing were collected for proteomic profiling. Differentially expressed genes and proteins were analyzed by Kyoto Encyclopedia of Genes and Genomes and STRING database. Selected targets were validated by quantitative PCR and Western blotting. Both MKO and SKO mice developed significant hyperopic shifts, with extensive transcriptomic and metabolic remodeling. When subjected to LIM, MKO mice exhibited exacerbated myopic shifts and lower retinal DA levels. Integrated proteomic analyses identified dopaminergic synapse-related alterations shared by Opn1mw deletion and lens-induced defocus. A convergent protein network involving TFAM, KDM5C, and SMN1, molecules linked to mitochondrial homeostasis, chromatin regulation, and RNA processing/neuronal maintenance, was consistently downregulated by M-opsin deficiency and further exacerbated by lens-induced defocus. Pharmacological activation of D1 receptors with SKF38393 attenuated LIM in MKO mice and increased TFAM and SMN1 protein levels, providing functional support for the involvement of impaired dopaminergic signaling in the enhanced myopia susceptibility of MKO mice. M-opsin dysfunction is associated with reduced retinal dopaminergic tone and increased susceptibility to LIM, consistent with a gene-environment dual-hit framework. A dysregulated TFAM/KDM5C/SMN1-associated molecular network may mark a vulnerable retinal state predisposing the eye to environmentally induced myopia.\n\nID: 42404897\nTitle: Identification and validation of platelet activation-related signatures in ulcerative colitis: a study based on machine learning and single-cell transcriptomic analysis.\nAbstract: Platelet activation (PA) acts as a molecular bridge connecting thrombosis and inflammation. This study aimed to identify key PA-related genes (PARGs) in ulcerative colitis (UC), and explore their transcriptional associations with immune-stromal dysregulation. Transcriptomic data of UC patients were obtained from the GEO database, and PARGs were retrieved from the MSigDB database. Differential expression analysis, WGCNA, LASSO, SVM-RFE, and random forest algorithms were applied to the GSE87466 dataset to identify key genes. Functional enrichment and immune infiltration analyses were performed to characterize their biological features. Additionally, single-cell RNA sequencing (scRNA-seq) analysis of the GSE214695 dataset was conducted to clarify their expression and localization. Findings were validated using independent GEO cohorts (GSE47908, GSE38713, and GSE36807) and qRT-PCR in a dextran sodium sulfate (DSS)-induced colitis mouse model. We identified 22 PARGs in UC, which were associated with extracellular matrix (ECM) remodeling, platelet activation, and immune cell recruitment. Machine learning algorithms refined these to three key genes: SPARC, TIMP1, and SERPINA1. ROC analysis demonstrated robust diagnostic performance (AUC\u00a0> 0.8) across the training and external validation cohorts. Crucially, single-cell analysis revealed that these genes were predominantly expressed in intestinal fibroblasts. Their expression levels strongly correlated with the infiltration of pathogenic immune cells (e.g., M1 macrophages, neutrophils). Additionally, an upstream regulatory network predicted transcription factors such as NFKB1 and SP1 as potential regulators. Finally, qRT-PCR confirmed the significant upregulation of these three genes in the DSS-induced colitis model. This study highlights the role of platelet activation in UC; identifies SPARC, TIMP1, and SERPINA1 as potential biomarkers; and provides important insights for the diagnosis and development of therapies for UC.\n\nID: 42404879\nTitle: Integrative multi-omics profiling reveals coordinated immunometabolic reprogramming and host-microbiome interactions in acute pancreatitis.\nAbstract: Acute pancreatitis (AP) is a life-threatening inflammatory disorder characterized by diverse etiologies and complex pathophysiological mechanisms involving immune dysregulation, systemic metabolic reprogramming, and gut microbiota disturbances. Although single-omics studies have provided partial insights into AP pathogenesis, comprehensive integrative multi-omics analyses investigating the intricate interactions among immunity, metabolism, and the microbiome in AP remain limited. We conducted an integrative multi-omics analysis of peripheral blood transcriptomics, untargeted plasma metabolomics, and fecal whole-metagenome sequencing in 15 patients with AP and 15 age- and sex-matched healthy controls. Differentially expressed genes (DEGs), metabolites (DEMs), and gut microbial species (DGMs) were identified. Subsequently, functional enrichment analysis, correlation network analysis, and exploratory machine learning approaches were employed to investigate molecular interactions and identify candidate biomarkers. Transcriptomic profiling identified 4, 776 DEGs, including 409 immune-related genes significantly enriched in the NF-\u03baB, IL-17, and cytokine-cytokine receptor interaction pathways, indicating pronounced inflammatory activation. Metabolomic analysis detected 296 DEMs, with prominent alterations in amino acid and lipid metabolism, mong which 9 metabolites showed potential discriminatory value (AUC > 0.75), with representative metabolites including xanthine, homocarnosine, and tetradecanedioic acid. Metagenomic sequencing revealed significant microbial compositional and functional remodeling, characterized by enrichment of pro-inflammatory taxa such as Escherichia coli and Streptococcus anginosus, alongside depletion of SCFA-producing commensals including Faecalibacterium prausnitzii and Blautia wexlerae. Functional profiling demonstrated disrupted amino acid metabolism, gut-brain signaling, and SCFA synthesis. Multi-omics integration revealed 215 significant correlations between host genes, metabolites, and microbes, highlighting key interaction hubs. An exploratory random forest model identified Lachnospira pectinoschiza, Megamonas funiformis, and SRGN as candidate biomarkers, showing promising classification performance within the current cohort (AUC = 0.951). This study provides a systems-level characterization of the immune, metabolic, and microbial alterations in AP. The identified molecular signatures and cross-omics interaction networks offer mechanistic insights into AP pathogenesis and highlight candidate biomarkers that warrant further validation in larger, independent cohorts.\n\nID: 42404762\nTitle: COL1A1 and SERPINE1 as Potential Therapeutic Targets in Diabetic Retinopathy: A Study Incorporating RNA Transcriptomics, Single-Cell RNA Sequencing, and Proteomics.\nAbstract: Diabetic retinopathy is caused by chronic hyperglycemia, which damages the retina's blood vessels and neurons. This study is aimed at identifying potential therapeutic targets for DR. Transcriptomic and proteomic data were obtained from the Gene Expression Omnibus (GEO) and ProteomeXchange databases, respectively. Differentially expressed genes (DEGs) and differentially expressed proteins (DEPs) were intersected. An enrichment analysis of the overlapping genes was performed based on the DAVID database. A protein-protein interaction (PPI) network (STRING) was analyzed via Cytoscape/cytoHubba to identify key genes. Single-cell RNA-sequencing (scRNA-seq) data were processed using Seurat. Gene set enrichment analysis (GSEA) (clusterProfiler) and molecular docking (EnrichR) were performed. High glucose-induced retinal microvascular endothelial cells (RMECs) were used for functional assays. The intersection of DEGs and DEPs yielded shared genes, enriched in the PI3K-Akt signaling pathway, AGE-RAGE signaling pathway in diabetic complications, complement and coagulation cascades, and ECM-receptor interaction; a PPI network incorporating these genes revealed two key DR-associated highly expressed genes, COL1A1 and SERPINE1. GSEA showed that samples with high expression of these key genes were enriched in pathways such as reactome signaling by TGFB family members, inflammatory response, TGF-\u03b2 signaling, and reactome cell extracellular matrix interactions. Single-cell and molecular docking analyses revealed high expression of the two key genes in fibroblasts and binding between SERPINE1 and paricalcitol, and HG induction increased their levels in RMECs, whereas knockdown of SERPINE1 repressed RMEC proliferation, migration, and invasion in vitro. This study identifies SERPINE1 and COL1A1 as possible DR therapeutic targets, providing new insights into relevant therapeutic development.\n\nID: 42402496\nTitle: A multi-scale graph frequency network for structural and functional region analysis in spatial transcriptomics.\nAbstract: Spatial transcriptomics enables the systematic exploration of how gene expression patterns are organized within intact tissues, yet effective analysis remains difficult due to the complexity of spatial dependencies and multi-scale tissue architectures. Here, we present the Spatial Graph Frequency Network (SGFN), a deep learning framework that integrates graph signal processing, graph attention, and contrastive learning to jointly model spatial topology and molecular features. Central to SGFN is a frequency-domain enhancement module that decomposes spatial graphs into multi-scale spectral components using the Laplacian eigenbasis, complemented by adaptive wavelet denoising when the retained graph-frequency sequence length permits valid decomposition. Evaluation across diverse biological systems-including the human dorsolateral prefrontal cortex, mouse brain, human breast cancer, osmFISH, MERFISH, STARmap, mouse embryonic development, head and neck angiosarcoma, and brain metastasis-shows that SGFN achieves improved or competitive performance relative to representative baseline methods in reference-based benchmarks, and identifies biologically coherent spatial or functional regions in unlabeled datasets supported by marker-gene, spatial-autocorrelation, cell-type-colocalization, and pathway-enrichment evidence. SGFN accurately reconstructed cortical layer architecture in the human brain, delineated immune and metabolic modules in tumors, and revealed spatiotemporal trajectories during embryogenesis. By combining interpretable frequency-domain representations with data-driven learning, SGFN provides a unified computational framework for decoding tissue organization and molecular heterogeneity, advancing the understanding of developmental, physiological, and pathological spatial systems.\n\nID: 42400792\nTitle: Calculating Relative Chimeric RNA Expression with FusionBlaster.\nAbstract: Chimeric RNA molecules-formed from nucleotide sequences of multiple genes-can arise through chromosomal rearrangements, transcriptional read-through events, or trans-splicing between distinct transcripts. These chimeric RNAs have been shown to play functional roles in both disease states and normal physiological processes, underscoring their biological relevance. Despite this, there are currently a limited number of tools available that aim to quantify chimeric RNA expression. Here, we introduce a metric called the Relative Index of Chimeric Expression (RICE), which assesses the expression of chimeric transcripts relative to their corresponding wild-type parental transcript, and we describe an easy-to-use bioinformatic tool called FusionBlaster for calculating RICE values from RNA sequencing data. After following this guide, users can apply the FusionBlaster pipeline to perform differential RICE analysis on their own RNA sequencing data by applying the appropriate statistical methods.\n\nID: 42400787\nTitle: Assembly of a Full-Length Chimeric RNA Transcriptome.\nAbstract: Chimeric RNAs are a class of understudied transcripts, characterized by their possession of sequence from two unique annotated parental transcripts. Definitionally, chimeric RNAs exist within gaps in annotation, and most efforts to catalog chimeric RNAs at scale have leveraged short-read paired-end RNAseq. While these have successfully established putative \"chimeromes\" in different tissue and disease contexts, chimeric RNAs predicted via short-read sequencing are defined by the chimeric exon-exon junction, and cannot provide information on the full-length isoforms which contain this junction. These gaps can be remedied by integration of these predictions with full-length, single-molecule, long-read sequencing. In this chapter, we provide instruction on how to integrate long-read sequencing with existing chimeric RNA predictions to establish full-length annotations of long-read transcripts.\n\nID: 42400785\nTitle: Detection of Chimeric RNAs from RNA-Seq Data with ChiTaRS 8.0: Insights for Liquid Biopsy and Drug Target Identification.\nAbstract: Chimeric RNAs (chiRNAs), generated via genomic rearrangements or splicing events, are increasingly recognized as biomarkers and therapeutic targets in cancer and neurodegenerative disorders. This chapter introduces an integrative framework for high-confidence chiRNA identification leveraging the ChiTaRS 8.0 database and the ChiTaH pipeline. ChiTaRS 8.0 encompasses 47,445 human chiRNAs, 1,055 Hi-C breakpoints, and 1,598 drug targets, while ChiTaH facilitates disease-specific analysis of RNA-seq data from 250 peripheral blood mononuclear cell (PBMC) samples-including glioblastoma and oral squamous cell carcinoma-and 199 healthy controls. Our approach combines reference-based fusion detection, BLAT validation against GRCh38, gene-pair compatibility checks, and protein domain conservation analysis. Functional annotation and protein-protein interaction modeling uncovered oncogenic chiRNAs absent from existing databases, exhibiting tissue-specific patterns. In Alzheimer's disease, liquid biopsy analyses identified unique chimeras-such as ENO1-MCUR1 and APOE-APOE-in cerebrospinal fluid, linked to neurotransmitter pathways and amyloid processing, and absent in healthy samples, highlighting their potential as early biomarkers. We describe a scalable digital hospital framework integrating AI-driven fusion detection, relational databases, and clinical metadata for real-time diagnostics and patient monitoring. This system supports fusion-targeted drug discovery and patient stratification, bridging translational gaps in oncology and neurodegeneration. By coupling computational pipelines with multiomics data, our approach advances personalized medicine while addressing challenges in artifact filtering and functional validation. Ultimately, the ChiTaRS-ChiTaH platform offers a versatile tool for chiRNA discovery and annotation across diverse disease contexts, providing insights into molecular mechanisms and clinical applications.\n\nID: 42400784\nTitle: Identification of Cross-Strand Chimeric RNAs with cscMap.\nAbstract: Chimeric RNAs could be originated from chromosome rearrangements at the DNA level or from posttranscriptional RNA fusion events, such as trans-spicing between distal genes and cis-splicing between adjacent genes. In addition to the mechanisms above, we have identified a new type of chimeric RNA, cross-strand chimeric RNA (cscRNA), which are fusion products of the transcripts encoded by the two opposite DNA strands. In this chapter, we present the workflow of cscMap, a specialized bioinformatics pipeline designed for de novo identification of the cscRNAs, directly from RNA deep sequencing data without prior annotations. cscMap employs a series of meticulous measurements to ensure high accuracy in detecting cross-strand junction events. This approach and the cscRNA species could serve as a valuable resource for further exploration of the origins and functions of cscRNAs.\n\nID: 42400783\nTitle: Integrative Chimeric RNA Prediction with FASfuse.\nAbstract: Chimeric RNAs are composed of sequences from different genomic loci caused by various chromosomal rearrangements and splicing events. They are recognized as both biomarkers present in cancer as well as a source of transcriptomic diversity in normal tissues. Numerous computational prediction tools have been developed and aim to analyze and predict chimeric RNAs. However, the performance of these tools vary in accuracy and depend on the sequencing context, necessitating a combination of multiple existing tools to produce the most comprehensive and accurate results. First, this study reviews several major chimeric RNA prediction tools: STAR-Fusion, Arriba, and FuSeq. It highlights the advantages of each program, as demonstrated by benchmarking studies. Second, it presents an integrated pipeline that combines all three top-ranking programs to produce a single output file including detailed annotations, such as chimeric RNA class, breakpoint types, and protein coding potential. The final computational product is a unified framework that supports results for high-confidence fusion transcript predictions for both research and clinical applications.\n\nID: 42399536\nTitle: Proteomic analysis reveals divergent inflammatory mechanisms of COVID-associated Guillain-Barr\u00e9 syndrome.\nAbstract: Guillain-Barr\u00e9 syndrome (GBS) is an acute immune-mediated neuropathy triggered by infections, with poorly understood pathophysiological diversity. COVID-19-associated GBS (COVID-GBS) is a rare but severe post-infectious condition, and its immune mechanisms remain unclear. We profiled immune mediators in cerebrospinal fluid (CSF) and serum from COVID-GBS patients, comparing them to non-COVID GBS (Control-GBS), COVID-19 patients without neurological complications (COVID-no-GBS) and non-inflammatory neuropathy controls (Neuropathy-no-GBS). To gain mechanistic insights, we integrated publicly available single-nucleus transcriptomic data from sural nerve biopsies of neuropathy patients. IL-8 was confirmed as a key cytokine in GBS. Analysis of publicly available single-nucleus transcriptomic data from non-GBS sural nerve biopsies suggested myeloid cells as potential sources of IL-8, with evidence of autocrine signaling capacity. LIF and CD8A emerged as novel biomarkers, with this transcriptomic analysis indicating that LIF receptor components are expressed on endothelial and stromal cells, suggesting these as potential cellular targets. COVID-GBS patients exhibited unique CSF alterations and distinct serum profiles marked by altered NK cell activity, cytotoxic T-cell responses, and myeloid differentiation. Moreover, associations between inflammatory, extracellular matrix, and regulatory markers with clinical disability differed between COVID-GBS and Control-GBS, pointing to divergent immune mechanisms. Our findings suggest that GBS involves myeloid-driven cytokine responses and local LIF signaling. Analysis of publicly available transcriptomic data from non-GBS sural nerve biopsies suggests potential cellular sources and targets, though validation in GBS-affected tissue is needed. COVID-GBS features a distinct immune signature involving localized and systemic inflammation. These insights deepen our understanding of GBS pathogenesis and nominate candidate biomarkers for further validation and potential therapeutic targeting.\n\nID: 42399103\nTitle: Integrative Multi-Omics Analysis Reveals the Tumor-Suppressive and Immunoregulatory Roles of SEMA5B in Prostate Cancer.\nAbstract: SEMA5B plays an important role in the maintenance of neural development and is highly environment dependent in tumorigenesis. The roles of SEMA5B in prostate cancer remain underexplored. This study investigates SEMA5B's functions in prostate cancer, revealing its role as a tumor suppressor transcriptionally regulated by androgen receptor and uncovering novel biomarkers and potential immunotherapeutic mechanisms. We analyzed SEMA5B's expression in cancer and its spatial association with cells in the tumor microenvironment using single-cell transcriptome sequencing datasets and spatial transcriptome sequencing samples. Using bulk RNA-seq data, we analyzed the immune infiltration of SEMA5B in prostate cancer. The association of SEMA5B with androgen receptor signaling and with metabolic pathways was evaluated by transcriptome and enrichment analysis. The phenotypes, cell cycle, apoptosis, and mitochondrial metabolic function of prostate cancer cell lines were further evaluated. SEMA5B regulation by androgen receptor was examined by gene knockdown, androgen/enzalutamide treatment, and epigenomics. Finally, the effect of SEMA5B on prostate cancer in\u00a0vivo was detected by tumor xenograft model. Pan-cancer single-cell analysis revealed that SEMA5B's expression showed significant tumor type specificity and spatially correlated with immune cell infiltration. SEMA5B is associated with abundant lymphocyte and immune-inflammatory microenvironment in prostate cancer. SEMA5B overexpression inhibited tumor cell proliferation, migration, and invasion. Moreover, high SEMA5B is associated with oxidative phosphorylation and low glycolytic profile. SEMA5B expression is positively correlated with androgen receptor. Androgen receptor inhibition and androgen stimulation affected the expression of SEMA5B. ChIP confirmed the binding of androgen receptor to the SEMA5B promoter. Finally, SEMA5B was verified to induce cell cycle arrest and apoptosis and reduce tumor growth. SEMA5B inhibits tumor malignant phenotype and is associated with immune-inflammatory tumor microenvironment. SEMA5B can regulate mitochondrial oxidative metabolism and induce cell cycle arrest and cell apoptosis, inhibiting the growth of prostate cancer.\n\nID: 42397593\nTitle: Network toxicology and multi-omics identify potential interactions between between air pollutants and interferon-related signaling in tuberculosis.\nAbstract: Air pollution increases tuberculosis (TB) susceptibility, yet the underlying molecular mechanisms remain elusive. We integrated human genes associated with seven air pollutants with TB-associated genes from public databases. Utilizing network toxicology, we engineered a diagnostic pipeline evaluating 175 machine learning models across transcriptomic datasets to identify a core gene signature. This signature was validated via qPCR in an independent clinical cohort. Molecular docking and in silico single-cell knockout analyses were used to predict pollutant-protein interactions and potential downstream transcriptional perturbations. We identified 271 intersecting genes enriched in inflammatory and immune-related pathways, including IL-17, TNF, and Toll-like receptor signaling. Machine learning identified a five-gene candidate signature consisting of STAT1, IFIH1, IFIT2, IFIT3, and CYBB. Clinical qRT-PCR further supported their upregulation in TB patients, with individual AUCs ranging from 0.76 to 0.89. Docking simulations predicted that toluene may form hydrophobic interactions with STAT1, IFIT2, and IFIT3. In silico STAT1 perturbation in monocytes predicted transcriptional alterations involving RETN and S100A9, with enrichment in IFN-\u03b3-related pathways. Air pollutants, particularly toluene and benzene, may contribute to TB susceptibility by interacting with interferon-related immune proteins. The identified five-gene signature may represent a potential biomarker panel for TB and warrants further validation in exposure-characterized cohorts.\n\nID: 42397569\nTitle: RNA modifications as innovative pharmaceutical targets: emerging drug delivery strategies and precision therapeutics for cancer immunotherapy and metabolic diseases.\nAbstract: RNA modifications have emerged as an important regulatory layer that influences gene expression beyond conventional genetic and epigenetic mechanisms. Among the various epitranscriptomic modifications, N6-methyladenosine (m6A), 5-methylcytosine (m5C), and pseudouridine (\u03a8) have been extensively investigated for their roles in RNA stability, splicing, translation, immune regulation, and metabolic homeostasis. Increasing evidence suggests that dysregulation of these modifications contributes to cancer progression, immune evasion, therapeutic resistance, and metabolic disorders, suggesting their potential as therapeutic targets. This review summarizes recent advances in endogenous epitranscriptomic RNA modifications and discusses their relevance in cancer immunotherapy and metabolic diseases. In addition, emerging therapeutic approaches targeting RNA-modifying enzymes, including writers, erasers, and readers, are discussed along with the development of antisense oligonucleotides, RNA-based therapeutics, and delivery systems. Recent progress in lipid nanoparticles, polymeric carriers, and targeted delivery platforms has improved the stability, specificity, and translational potential of RNA-targeted therapies. The review also highlights current challenges associated with clinical translation, including delivery efficiency, therapeutic specificity, and patient heterogeneity. Overall, epitranscriptomic RNA modifications may provide new opportunities for the development of precision therapeutic strategies for cancer and metabolic diseases.\n\nID: 42397457\nTitle: Recent advances in the detection and functional analysis of circRNAs with short-read RNA sequencing-based methods.\nAbstract: Circular RNAs (circRNAs) were first identified approximately 50 years ago in pathogenic viroids as single-stranded, covalently closed RNA molecules. Initially considered by-products of splicing, circRNAs are now recognised as an important class of regulatory RNAs involved in microRNA sponging, RNA-protein interactions, and cellular pathways. Their closed-loop structure, generated through backsplicing, confers resistance to exonucleolytic degradation and contributes to their stability. Owing to their tissue- and disease-specific expression, circRNAs have emerged as promising biomarkers for cancer, neurodegenerative disorders, and cardiovascular disease. Over the past decade, numerous bioinformatics tools utilising RNA-sequencing (RNA-seq) data have been developed for circRNA detection and analysis. Detection methods have evolved from manual split-read inspection to automated identification of the back spliced junction, while annotation pipelines now resolve the genomic origins and structural characteristics of circRNAs. Because individual circRNA callers vary considerably in sensitivity and specificity, a combined usage of tools in circRNA detection has become the preferred strategy for generating high-confidence datasets. Beyond their non-coding functions, increasing evidence suggests that some circRNAs possess protein-coding potential through open reading frames, cap-independent translation mechanisms, internal ribosome entry sites (IRESs), and N6-methyladenosine modifications. A new generation of bioinformatic tools can now assess the protein-coding potential of circRNAs, integrating the above features, as well as machine learning and deep learning approaches refining these predictions. This review summarises recently developed short-read RNA-seq bioinformatics tools for circRNA detection, consensus calling, annotation, and protein-coding potential prediction, with a particular focus on advances from the past five years that facilitate the identification of translatable circRNAs.\n\nID: 42409435\nTitle: Toward Bridging the Gap from Artificial Intelligence in Clinical Research to Clinical Practice in Rheumatology: The Mayo Experience.\nAbstract: This article highlights Mayo Clinic's pioneering efforts to integrate artificial intelligence (AI) and machine learning into rheumatology, focusing on genomics, imaging, pathology, and clinical data science to improve diagnosis, treatment and operational efficiency. Key innovations include transformer-based models for genomic analysis, autonomous ultrasound devices, multimodal imaging solutions, and generative AI tools for clinical documentation and patient education, all aimed at bridging the gap between research and routine clinical care. The article emphasizes the need for rigorous validation, explainable AI, electronic health records integration, clinician training, and global collaboration to ensure safe and effective adoption of AI-powered tools in clinical practice.\n\nID: 42333573\nTitle: Application of deep learning in crop research: From genomics to phenomics.\nAbstract: Deep learning, as a pivotal branch of machine learning, has demonstrated remarkable potential in advancing crop science by effectively integrating genomics and phenomics. This review systematically outlines the application of diverse deep learning architectures-such as convolutional neural networks, recurrent neural networks, and transformers-across key crop genomic tasks, including gene expression prediction, alternative splicing analysis, cis-regulatory element identification, epigenomic profiling, and genome-based trait prediction. In phenomics, these models facilitate high-throughput extraction of crop phenotypic traits from multispectral, unmanned aerial vehicle, and ground-based imagery, supporting yield forecasting, disease diagnosis, and stress response monitoring. We critically evaluate the performance and limitations of each model type across tasks, considering trade-offs between complexity, accuracy, and interpretability, to offer practical guidance for crop researchers. Additionally, the review addresses major challenges in deploying deep learning-such as data scarcity, model transparency, and computational demands-and proposes future pathways to enhance model generalizability, multimodal data integration, and applications in intelligent breeding and sustainable agriculture. Deep learning, a powerful form of artificial intelligence, is opening new doors in crop science by connecting the dots between a plant's genetic code and how it actually grows in the field. In this review, we explore how different deep learning models help scientists tackle two big challenges: predicting gene behavior and extracting useful information from crop images captured by drones and cameras. These models can forecast traits like yield and disease resistance based on genetic data, while also enabling early detection of pests, diseases, and stress responses from field images. We also compare the strengths and weaknesses of various approaches to help researchers choose the right tool for their needs. Although challenges like data limitations and high computing demands remain, deep learning holds great promise for making crop breeding smarter and agriculture more sustainable.\n\nID: 42328788\nTitle: SpliceSelectNet: a hierarchical Transformer-based deep learning model for splice site prediction.\nAbstract: Accurate RNA splicing is essential for gene expression and protein function, yet the mechanisms governing splice site recognition remain incompletely understood. Aberrant splicing caused by mutations can lead to severe diseases, including cancer and genetic disorders, underscoring the need for accurate computational tools to predict splice sites and detect disruptions. Existing methods have made significant advances in splice site prediction but are often limited in handling long-range dependencies due to high computational costs, a factor critical to splicing regulation. Moreover, many models lack interpretability, hindering efforts to elucidate the underlying biological mechanisms. Here, we present SpliceSelectNet (SSNet), a hierarchical Transformer-based deep learning model that predicts splice sites from DNA sequences spanning up to 100 kb. By integrating local and global attention mechanisms, SSNet efficiently captures both proximal and distal regulatory signals while maintaining single-nucleotide resolution. Across multiple benchmark datasets, SSNet achieves state-of-the-art performance in splice site prediction and aberrant splicing detection. Systematic in silico mutagenesis demonstrates that attention scores reflect functional sequence importance, supporting their biological relevance. Long-range sequence perturbation experiments further show that SSNet captures distal regulatory effects beyond conventional receptive fields. Together, these results establish SSNet as a biologically interpretable framework for modeling long-range splicing regulation from genomic sequence.\n\nID: 42323878\nTitle: Comprehensive review and assessment of multi-species splicing variant prediction: task-specific deep learning models and genomic foundation models.\nAbstract: Alternative splicing generates transcriptomic and proteomic diversity essential for eukaryotic complexity, yet genetic variants disrupting the splicing code underlie numerous human diseases. Deep learning (DL) models and genomic foundation models (GFMs) have achieved outstanding accuracy for predicting splicing variant effects in humans. However, their transferability to non-human species remains poorly understood, limiting applications in agricultural genomics, comparative biology, and non-model organism research, where experimentally validated variant datasets are limited or lacking. In this study, we comprehensively reviewed 35 computational approaches in terms of their architectural characteristics for splicing site and variant prediction and analysis. We systematically benchmarked the performance of 10 representative models for splicing variant prediction across human, rat, pig, and chicken, including four task-specific DL models and six GFMs, using our manually assembled benchmark datasets. Our benchmarking results revealed a substantial cross-species performance decrease (~21%-33% in the area under the receiver operating characteristic curve - AUROC) using task-specific models from human to non-human species datasets. We then applied a supervised adaptation to frozen GFM embeddings (DNABERT-2, Evo 2, Genos) by adding a lightweight classifier (i.e. a multi-layer perceptron) and reduced the cross-species performance decrease for rat and pig (8.56%-23.84% in AUROC), while performance on chicken was very close to human (decline within 1%, even exceeding by 0.52% when using the Evo 2 embedding). We proposed several directions to improve the prediction performance of splicing variants, including feature representation transfer and multi-modal fusion integrating global context, universal embeddings, and species-aware conditioning. We hope our comprehensive review and performance benchmarking can provide useful computational insights for further advancement of splicing variant prediction.\n\nID: 42254864\nTitle: Human iPSC-derived motor neurons as a platform for elucidating TDP-43-related amyotrophic lateral sclerosis pathogenesis: a mini review.\nAbstract: TAR DNA-binding protein 43 (TDP-43) is a major pathogenic RNA-binding protein associated with amyotrophic lateral sclerosis (ALS). Heterozygous mutations in TDP-43 cause familial ALS, known as ALS10. TDP-43 is predominantly localized in the nucleus under physiological conditions. Not only ALS patients with TARDBP mutations but also the majority of sporadic ALS patients exhibit TDP-43 pathology, which is defined by nuclear clearance and cytoplasmic aggregation. The inclusion of cryptic exons in genes such as STMN2 and UNC13A has emerged as a hallmark of TDP-43 loss of function, as demonstrated in TDP-43 knockdown models and postmortem analyses. However, it is not yet clear how TDP-43 levels and location change from healthy to pathological conditions in ALS. Motor neurons derived from induced pluripotent stem cells (iPSCs) have been widely used in ALS research and provide a promising platform to investigate early-stage disease mechanisms. However, challenges remain in generating models that faithfully recapitulate ALS pathogenesis. In this review, we summarize recent advances in TDP-43-related iPSC-derived motor neuron models and discuss future perspectives for elucidating ALS pathogenesis. We propose that longitudinal analyses of TDP-43 dynamics and co-culture systems will be essential to better model early ALS pathogenesis.\n\nID: 42247039\nTitle: Resolving variants of uncertain significance in neurofibromatosis: An integrated approach combining deep learning and minigene assays.\nAbstract: Neurofibromatosis (NF) comprises genetic disorders mainly caused by pathogenic variants, yet its phenotypic and genotypic heterogeneity complicates diagnosis. We analyzed clinical and genomic data from 97 NF patients using targeted panels, whole-exome sequencing (WES), and whole-genome sequencing (WGS) from June 2020 to October 2024. Variants were classified according to established guidelines, and their distribution across protein domains was evaluated using Bayesian multinomial logistic regression. Deep-learning prediction tools and minigene splicing assays were applied to assess variants of uncertain significance (VUS). Sixty-nine variants were identified in NF1, NF2, and LZTR1, including 22 novel ones. In NF1, pathogenic deletions were enriched in non-domain regions, while substitutions predominated in domain regions, though without phenotype-specific associations. Two of three VUS were predicted and experimentally confirmed as pathogenic. One case achieved molecular diagnosis only through WGS after negative WES results. This study expands the mutational landscape of NF genes, underscores the diagnostic advantage of WGS, and demonstrates the effectiveness of advanced predictive and functional tools for VUS interpretation.\n\nID: 42242678\nTitle: Pathogenicity prediction for noncanonical splice-altering variants based on multimodal feature fusion.\nAbstract: Splice-altering variants (SAVs) are the second most prevalent class of pathogenic genetic variants and are strongly associated with the occurrence and development of various diseases. However, current computational tools exhibit limited predictive capability beyond canonical GT-AG splice sites, making accurate assessment of noncanonical SAV pathogenicity a considerable challenge. To address this limitation, we developed MOSAIC (multimodal feature fusion for noncanonical splice-altering variants pathogenicity prediction), a deep learning framework designed for precise assessment of noncanonical SAV pathogenicity. MOSAIC integrates long-range contextual signals derived from a pretrained DNA language model, local sequence features captured from multi-scale convolutional neural networks, and functional annotations. By employing a transformer encoder and a gated fusion module, the model adaptively integrates these multimodal features. Benchmarking across multiple independent datasets demonstrated that MOSAIC consistently outperforms existing state-of-the-art methods, such as CADD and SpliceAI. It remains highly accurate and robust when evaluated on rare variants, gene-independent contexts, and the largest subset where all comparative methods yielded outputs. Furthermore, feature importance analysis revealed that long-range dependencies in DNA sequences and transformer-based integration were critical contributors to model performance. Interpretability analyses indicated that MOSAIC could identify key regulatory sequence motifs associated with transcription factors and RNA-binding proteins, offering mechanistic insight into how noncanonical SAVs disrupt splicing regulation and contribute to pathogenic processes. Overall, MOSAIC offers an accurate and interpretable framework for predicting the pathogenicity of noncanonical SAVs, thereby serving as a dependable computational tool for genetic diagnostics and precision medicine applications. MOSAIC source code and data are available at https://github.com/Lilab-genomics/MOSAIC.\n\nID: 42235113\nTitle: 3D craniofacial generative model for surgical planning in mandibular reconstruction.\nAbstract: Mandibular reconstruction following segmental resection for oral tumors is a complex procedure necessitating precise restoration of both masticatory function and facial aesthetics. Current Computer-Assisted Surgery (CAS) workflows remain fragmented, relying on subjective manual mirroring for shape completion and labor-intensive, non-standardized CAD operations for fibula osteotomy planning. Furthermore, existing deep learning approaches predominantly address mandibular shape completion in isolation, failing to integrate surgical feasibility or predict postoperative soft-tissue outcomes. In this paper, we propose a unified craniofacial generative framework that orchestrates mandibular completion, automated surgical planning, and postoperative facial prediction within a single pipeline. We employ a 3D latent diffusion model with patch-wise encoding strategy, pre-trained on a large-scale cohort of tumor-free subjects, to learn a robust anatomical shape prior. This prior is adapted via a specialized encoder to perform high-fidelity completion of defective mandibles. Subsequently, we introduce a geometric optimization algorithm based on dynamic programming to automatically generate fibula osteotomy and splicing plans that strictly adhere to the reconstructed mandibular contour. Finally, the framework predicts the postoperative facial morphology conditioned on the reconstructed bone, facilitating aesthetic outcome assessment. Validation on simulated and clinical datasets demonstrates that our framework achieves high anatomical fidelity in mandibular completion (Dice 85.61%, CD 1.43 mm) and precise postoperative facial prediction (Dice 97.67%, CD 1.57 mm). For surgical planning, the proposed algorithm improves reconstruction precision, achieving a volume ratio of 28.28%, a contour error of 2.24 mm, and a maximum projection of 3.55 mm compared with prior automated methods. Furthermore, the framework reduces the total planning time from over 34 min to under one minute, corresponding to a 60\u00d7 speedup, thereby supporting a practical and efficient paradigm for aesthetically aware surgical planning focused on the reconstructive phase. Our code is available at https://github.com/ShanghaiTech-IMPACT/3D-Craniofacial-Generative-Model-for-Surgical-Planning-in-Mandibular-Reconstruction.\n\nID: 42213808\nTitle: Generative modeling for RNA splicing prediction and design.\nAbstract: Alternative splicing (AS) of pre-mRNA plays a crucial role in tissue-specific gene regulation, with disease implications due to splicing defects. Predicting and manipulating AS can therefore uncover new regulatory mechanisms and aid in therapeutic design. We introduce TrASPr+BOS, a generative AI model with Bayesian Optimization for predicting and designing RNA for tissue-specific splicing outcomes. Transformer for Alternative Splicing Prediction (TrASPr) is a multi-transformer model that can handle different types of AS events and generalize to unseen cellular conditions. It then serves as an oracle, generating labeled data to train a Bayesian Optimization for Splicing (BOS) algorithm to design RNA for condition-specific splicing outcomes. We show TrASPr+BOS outperforms existing methods, enhancing tissue-specific AUPRC by up to 1.8-fold and capturing tissue-specific regulatory elements. We validate hundreds of predicted novel tissue-specific splicing variations and confirm new regulatory elements using dCas13. We envision TrASPr+BOS as a light yet accurate method researchers can probe or adopt for specific tasks.\n\nID: 42211755\nTitle: Integrated Genomic and Single-Cell Analysis Reveals Heterogeneity, Prognosis, and Treatment Vulnerability in Urothelial Carcinoma.\nAbstract: At the transcriptomic level, several molecular subtyping schemes have been established to elucidate the intrinsic heterogeneity of urothelial carcinoma and to inform prognostic assessment and therapeutic guidance. However, a unified molecular classification scheme characterizing genomic alterations is lacking. Unsupervised and supervised clustering identified two distinct mutational signature subtypes. Kaplan-Meier analysis demonstrated that patients with the MUT2 subtype had a higher risk of death than those with the MUT1 subtype across multiple cohorts, including IMvigor210 (hazard ratio [HR], 1.74; 95% confidence interval [CI], 1.27-2.37; p < 0.001), UC-GENOME (HR, 1.54; 95% CI, 0.93-2.54; p = 0.091), The Cancer Genome Atlas (TCGA; HR, 1.45; 95% CI, 1.06-1.98; p = 0.020), MSK2022 (HR, 1.34; 95% CI, 1.10-1.64; p = 0.004), MSK2015 (HR, 3.43; 95% CI, 1.36-8.64; p = 0.005), and the Tongji cohort (HR, 4.99; 95% CI, 0.57-43.69; p = 0.11). Immunotherapy response rates were significantly higher in the MUT1 subtype than in the MUT2 subtype in IMvigor210 (31.8% vs. 13.1%; p = 0.003) and UC-GENOME (42.3% vs. 29.0%; p = 0.022). Consistent with these findings, single-cell analysis showed that MUT2 tumors were enriched in tumor-associated fibroblast subpopulations and had a lower abundance of immune effector cells. Overall, this genomic analysis identified two mutation-based subtypes of urothelial carcinoma associated with patient prognosis and immunotherapy response.\n\nID: 42199078\nTitle: Transforming surgical decisions: the rise of predictive and personalized digital tools.\nAbstract: Artificial intelligence (AI) has the potential to profoundly transform surgical decision-making (SDM) by enabling more predictive, personalized, and data-driven care. Its integration across the surgical pathway can improve clinical outcomes, efficiency, and patient safety. This narrative review provides an overview of the current and emerging applications of AI in SDM. A structured search of electronic databases was conducted using PubMed, Scopus, Web of Science, and Google Scholar. The search primarily focused on peer-reviewed publications from 2015 to 2025. AI applications include radiologic image analysis for preoperative planning, electronic health record mining for individualized surgical strategies, risk and immunological response prediction, and genomic analysis to guide treatment selection. Intraoperative, AI-based video, image, and physiological data processing can support real-time decision-making by improving precision, identifying anatomical targets, and predicting complications earlier. Postoperatively, AI systems can monitor patient data to detect complications, evaluate outcomes, and tailor follow-up therapy. Despite these advantages, challenges remain, including data quality and availability, model explainability, and others. Overcoming these barriers requires explainable and secure AI models, scalable infrastructures, clinician engagement, and robust regulatory frameworks. Advances in AI-assisted robotics and interpretability are expected to support safer, more ethical, and more effective surgical decision-making.\n\nID: 42178983\nTitle: Protein Disulfide Isomerase Disassembles TDP-43/G3BP1 Condensates and Antagonizes TDP-43 Pathological Aggregates.\nAbstract: Cytoplasmic mislocalization and aggregation of transactive response DNA-binding protein-43 (TDP-43) is a common pathological feature of amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration, and Alzheimer's disease with TDP-43 pathology (AD-TDP); the exact role of protein disulfide isomerase (PDI), an enzyme with chaperone activity, in modulating the pathological behavior of TDP-43 is unknown. In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target.\n\nID: 42175405\nTitle: Mechanisms linking primary biliary cholangitis and osteoporosis: A combined clinical and molecular analysis.\nAbstract: Primary biliary cholangitis (PBC) is an immune-mediated cholestatic liver disease, and osteoporosis (OP) is a prevalent comorbidity that aggravates the disease burden of PBC patients. Although the co-occurrence of the 2 diseases has been widely observed, the underlying molecular mechanisms remain unclear. Herein, we evaluated the causal link between PBC and OP using Mendelian randomization (MR) and explored shared molecular mechanisms through bioinformatics and machine learning. We performed two-sample MR using genome-wide association study summary data for PBC and OP from the Integrative Epidemiology Unit database. Inverse-variance weighting was used as the primary MR method, with heterogeneity and horizontal pleiotropy tests performed to exclude potential biases. To explore shared molecular mechanisms, we analyzed transcriptomic datasets from the Gene Expression Omnibus database, identified comorbidity-associated differentially expressed genes, and applied multiple machine learning algorithms for biomarker screening and validation, combined with immune infiltration analysis. Our study showed that MR demonstrated that PBC significantly increases the risk of OP, while transcriptomic analysis identified 36 shared differentially expressed genes enriched in key biological pathways such as ribonucleic acid splicing and ubiquitin-mediated proteolysis. Furthermore, using 3 machine learning algorithms, we identified 12 PBC-specific and 4 OP-specific diagnostic genes, whose intersection revealed vacuolar protein sorting 37 homolog C (VPS37C) as a common diagnostic biomarker. In both diseases, VPS37C exhibited an area under the receiver operating characteristic curve value >0.7, demonstrating its robust predictive performance. In addition, VPS37C expression was found to be significantly correlated with the infiltration landscape of multiple immune cell types in both PBC and OP. This study identified VPS37C as a shared diagnostic gene linking PBC and OP, providing new insights into their comorbidity at both genetic and immune levels. Our findings further elucidate the molecular mechanisms underlying the comorbidity of PBC and OP, offer novel clues for understanding their pathogenesis, and highlight promising diagnostic and therapeutic targets for clinical application.\n\nID: 42171949\nTitle: Dual-attention bidirectional LSTM with feature genomic analysis improves prognostic survival prediction in colorectal cancer patients.\nAbstract: The increasing incidence and mortality rates of colorectal cancer necessitate accurate prediction of patients' prognostic survival time for better management, early screening, and extended lifespan. This study uses the TCGA public dataset to conduct differential analysis on lncRNAs in 39 diseased tissues and their normal counterparts from 413 colorectal cancer patient samples, identifying 458 differentially expressed lncRNAs (DELncRNAs). Univariate Cox regression analysis revealed 23 DELncRNAs significantly associated with overall survival (OS). These 23 DELncRNAs were further refined using the LASSO algorithm to determine their feature coefficients. An adaptive mining approach with dual-attention mechanisms was employed to explore the correlative properties between various factors and survival time. A bidirectional long short-term memory (BiLSTM) neural network was established for survival prediction. The model was validated using the Jiangnan University colorectal cancer dataset, demonstrating reliable predictions for patient survival and valuable support for clinical decision-making. The AUC values for patient survival prediction during the 3-year, 3-6 year, and 6-year periods were nearly 1.00, significantly outperforming other comparative trials.\n\nID: 42156927\nTitle: HELIX: a scalable model for predicting context-dependent regulation of RNA splicing and isoform usage.\nAbstract: Context-dependent alternative splicing plays a critical role in disease pathogenesis and organ development, but its complex regulation remains challenging to predict. Here, to address this, we developed HELIX, a hierarchical deep learning framework that integrates pre-mRNA sequence and RNA-binding protein expression profiles to predict tissue- and condition-specific splicing patterns and transcript isoform usage simultaneously. By leveraging both short-read and long-read RNA sequencing data during training, HELIX achieves greater accuracy than existing splicing prediction models and conventional short-read-based methods in predicting differential splicing events, splicing strength at highly regulated splice sites, and isoform usage. The model enables systematic identification of tissue-specific splicing quantitative trait loci and their functional impacts. Furthermore, HELIX predicts patient-specific splicing dysregulation with quantitative attribution to genetic variants and abnormal RNA-binding protein expression in colon cancer cohorts. Through transfer learning, the HELIX model can be adapted to single-cell RNA sequencing data, thereby enabling the prediction of cell-type-specific isoforms.\n\nID: 42149609\nTitle: Global whole-genome, phylodynamic, and machine-learning analysis of Glaesserella parasuis serovars 2, 5, and 12.\nAbstract: Glaesserella parasuis is a respiratory pathogen of swine and the causative agent of Gl\u00e4sser's disease. Among the 15 serotypes, serotypes 2, 5, and 12 represent globally disseminated, high-risk lineages characterized by increased virulence and antimicrobial resistance (AMR). To systematically investigate the global epidemiology and molecular basis of high-risk serotypes, we conducted a large-scale comparative genomic analysis. We assembled 1,004 G. parasuis genomes, including 102 newly sequenced isolates from diseased swine across 18 Chinese provinces and 902 publicly available genomes from 16 countries. Pan-genome analysis identified msmX as a novel marker for precise serotype 5/12 differentiation. Bayesian phylogeographic reconstruction then traced the dissemination history of these lineages: a highly antimicrobial-resistant lineage of serotype 2 likely originated in Japan and spread to the Americas via China in the late 1940s, whereas highly virulent lineages of serotypes 5 and 12 emerged in China before dispersing globally. Resistome and virulome profiling revealed distinct risk patterns: serotype 2 isolates carried more antimicrobial resistance genes (ARGs), while serotypes 5 and 12 harbored broader repertoires of virulence factors (VFs). Notably, we identified isolates co-harboring extensive suites of both VFs and ARGs, representing a convergent dual high-risk genomic profile. Furthermore, machine learning models identified signature genes significantly associated with AMR and virulence, which are implicated in pathways, such as cell wall synthesis, capsular polysaccharide production, and carbon source utilization. Taken together, these findings elucidate the global dissemination patterns and molecular foundations of high-risk serovars and provide critical evidence to guide targeted surveillance, clinical antimicrobial stewardship, and rational vaccine development.IMPORTANCEGlaesserella parasuis poses a global threat to swine health, with serovars 2, 5, and 12 representing high-risk lineages due to enhanced virulence and antimicrobial resistance. However, their global spread patterns and genetic basis remain poorly resolved. Through large-scale comparative genomics of 1,004 isolates, we resolved the transcontinental dissemination routes of these lineages and identified msmX as a novel marker to distinguish serotypes 5 and 12. We further uncover high-risk clones co-carrying extensive virulence and resistance gene repertoires. This study provides a population genomic framework for monitoring high-risk G. parasuis strains and informs the development of targeted vaccines and stewardship strategies to mitigate their impact.\n\nID: 42135847\nTitle: TDP-43: [GU]-ardian of the transcriptome.\nAbstract: TDP-43 is a ubiquitously expressed, primarily nuclear DNA/RNA-binding protein implicated in neurodegenerative diseases including amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD). In this review, we examine the structure and regulation of TDP-43, how these features influence its localization and functional activity, and how their disruption may contribute to disease. Among TDP-43's diverse functions, splicing repression of nonconserved RNA sequences termed cryptic exons has emerged as especially central to human disease. TDP-43 nuclear depletion and cytoplasmic aggregation are well-established pathological features in affected neurons and glia of neurodegenerative diseases, and accumulating evidence suggests that loss of TDP-43-mediated splicing repression occurs presymptomatically in disease. Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction. Here, we synthesize current knowledge of TDP-43 biology and curate datasets from human tissues and experimental models, focusing on cryptic splicing to provide a resource for leveraging cryptic exon biology to better understand, detect, and target TDP-43 dysfunction.\n\nID: 42127163\nTitle: Analyzing the performance of deep learning splice prediction algorithms.\nAbstract: SpliceAI is the leading tool for predicting splice-altering variants, but restrictive licensing limits clinical adoption. While open-source implementations have been published with author-reported comparisons, independent benchmarking across diverse datasets is needed to establish equivalence. We compared the original SpliceAI with two open-source implementations (OpenSpliceAI and CI-SpliceAI) and a legacy ensemble baseline across six datasets: a curated set of 1,316 validated variants, 213 variants with splice-assay data, 99,601 variants from the SPiP splicing prediction study, 242 manually curated deep intronic pathogenic variants, and two ClinVar-derived datasets comprising 53,600 intronic variants and 58,064 variants spanning all genomic contexts. The deep learning models were also evaluated against an ensemble of four legacy splice-prediction tools. Across all datasets, the deep learning algorithms outperformed the legacy ensemble. All three deep learning algorithms showed similar performance on the larger datasets dominated by canonical splice site variants (balanced accuracies 0.889-0.977). On the deep intronic benchmark, the original SpliceAI achieved the highest balanced accuracy (0.940), outperforming both CI-SpliceAI (0.890) and OpenSpliceAI (0.841). Critically, optimal thresholds for deep intronic variants were an order of magnitude lower than standard recommendations, indicating that default thresholds would miss the majority of pathogenic deep intronic variants. A correlation analysis showed that CI-SpliceAI maintained balanced concordance across event types, whereas OpenSpliceAI showed stronger correlation for loss events than gain events. Both implementations showed high positional agreement with SpliceAI, with exact splice-site match rates exceeding 90% across event types. Together, these results demonstrate that both open-source reimplementations of SpliceAI successfully reproduce the predictive behavior of the original algorithm across multiple evaluation contexts, while consistently outperforming traditional splice prediction methods. However, performance diverges on deeply intronic variants, and standard score thresholds are poorly calibrated for this variant class regardless of algorithm choice.\n\nID: 42126634\nTitle: Comparison between a conventional tool and deep learning models for RNA velocity analysis of scRNA-Seq data.\nAbstract: Single-cell RNA sequencing (scRNA-Seq) enables analysis of gene expression at single-cell resolution. RNA velocity analysis infers the temporal dynamics of transcriptional states from the relative abundances of spliced/unspliced mRNA quantified via scRNA-Seq.\u00a0Classical RNA velocity approaches, such as scVelo, implement gene-specific kinetic modeling. Deep learning methods including DeepVelo, VeloVI, LatentVelo, SymVelo, and scTour are based on variational autoencoders (VAEs), which allow to enhance the robustness and accuracy by leveraging nonlinear latent representations. Here, we systematically evaluated the performance of deep learning RNA velocity tools by comparing with the scVelo dynamical model to access the possible advantages of VAE-base methods. For this purpose, public datasets (GSE149689 and GSE203233) were initially processed using a standard scRNA-Seq pipeline. Comparisons among results of selected velocity tools were conducted using cosine similarity of velocity vectors to assess directional concordance, and by mean squared error analysis of trajectory continuity for the deep learning models. Overall, VAE methods produced significant, richer, and more directionally coherent and consistent velocity fields than the classical model. Our findings indicate that deep learning models provide more consistent and biologically plausible cell-state trajectories, although at the expense of higher computational demands and reliance on accurate splicing quantification. Altogether, our results underscore the relevance of VAE-based frameworks to advance RNA velocity analysis while highlighting the need for careful preprocessing.\n\nID: 42075717\nTitle: Genomic Analysis of Resistance to Exserohilum turcicum in Nigerien and Senegalese Sorghum Using GWAS and Machine Learning.\nAbstract: Sorghum, an essential crop in Niger, ranks second to pearl millet in importance for food, feed, and commerce. However, its yields are hindered by various factors, including diseases such as leaf blight caused by Exserohilum turcicum. In this study, field phenotypes were analyzed on 102 accessions (including checks SC748-5 and BTx623) grown and evaluated at two locations in Niger for leaf blight incidence and severity. The panel included accessions originally collected from Niger and Senegal. Genotypes were generated for 120 accessions, and GWAS/ML analyses were performed on 102 accessions due to missing phenotypic data. Among the accessions, S39, N23, and N38 exhibited mean leaf blight incidence below 50%, while S3, S43, N23, and N38 displayed the lowest severity levels, with a mean severity in Niger of 24.5 \u00b1 0.64. Accession N23 showed relatively low incidence and severity levels across the Niger field evaluations. Using genome-wide association studies and machine learning, candidate SNPs associated with leaf blight phenotypes were identified. Genes near these SNPs were associated with functions related to plant defense mechanisms and stress responses, providing preliminary targets for future validation in sorghum leaf blight studies.\n\nID: 42025161\nTitle: Comprehensive RNA-binding protein analyses and deep learning uncover genetic constraints and disease associations in protein-RNA interfaces.\nAbstract: RNA-binding proteins (RBPs) orchestrate post-transcriptional processes, including splicing, cleavage and polyadenylation, and translation. Our updated RBP resource integrates data from 92 additional RBPs (286 in total) profiled by enhanced CLIP (eCLIP), enabling comprehensive characterization of RNA elements within human K562 and HepG2 cells. To interrogate RBP-binding syntax, we trained deep-learning models on eCLIP profiles, allowing us to score genetic variants and quantify constraints on RBP-binding sites. We observed opposing selective-constraint profiles at splicing enhancers versus silencers, including an unexpected enrichment of strengthening mutations in ELAVL1- and HNRNPC-binding sites. Finally, our model prioritizes disease variants, exposing unexpected RBP-related mechanisms of pathogenesis, exemplified by the enrichment of weakening mutations in spliceosomal protein-binding sites among retinal disease variants. The complete eCLIP resource offers an integrated platform for exploring RBP-RNA interactomes.\n\nID: 42013476\nTitle: Cryptic Splicing in ALS: From Driving Disease Progression to Unlocking Novel Therapeutics.\nAbstract: TDP-43 is an RNA-binding protein that regulates multiple aspects of RNA processing, and its mislocalization from the nucleus to the cytoplasm is a defining feature of amyotrophic lateral sclerosis (ALS). While both loss- and gain-of-function mechanisms contribute to disease, the discovery of cryptic splicing has shed light on the downstream consequences of TDP-43 nuclear clearance for neuronal health. Here, we highlight how loss of nuclear TDP-43 can drive a cascade of events that lead to the impairment of cellular proteostasis and result in a positive feedback loop that perpetuates neuronal dysfunction. This sustains the appearance of cryptic splicing events in genes that are involved in key pathways for the maintenance of axonal homeostasis and synaptic transmission. In contrast to their detrimental effects on neuronal health, cryptic splicing mechanisms may be harnessed to develop novel therapeutic strategies, unprecedentedly expanding the availability of therapeutic avenues for TDP-43 proteinopathies.\n\nID: 41995061\nTitle: Machine Learning-Driven Ensemble Screening of Multitarget Kinase Inhibitors for Tauopathy-Associated Neurodegeneration Using All-Atom and Steered MD Simulations.\nAbstract: Tauopathies arise when normal functions of the tau protein in axonal transport and neuronal maintenance are disrupted by an imbalance between kinases and phosphatases. Dysregulation of key kinases such as dual-specificity Tyrosine-Regulated Kinase 1A (DYRK1A), Tau Tubulin Kinase 1 (TTBK1), and ABL Proto-Oncogene 1, and Non-Receptor Tyrosine Kinase (ABL1) drives excessive tau phosphorylation and neurofibrillary tangle accumulation. DYRK1A regulates MAPT exon 10 splicing and phosphorylates tau at multiple Ser/Thr residues, priming it for further phosphorylation by other kinases. TTBK1 phosphorylates tau at disease-associated epitopes within the microtubule-binding domain, promoting detachment from microtubules and aggregation. ABL1 phosphorylates tau at tyrosine residues, linking tau modification with A\u03b2-induced synaptic dysfunction. These events collectively drive tau hyperphosphorylation, misfolding, and neurofibrillary pathology characteristic of tauopathies. To identify natural product-derived multitarget inhibitors for these kinases, we developed a comprehensive machine learning (ML) workflow trained on bioactivity data from ChEMBL and BindingDB. We implemented five distinct classifiers: CatBoost, Support Vector Machine (SVM), k-Nearest Neighbors (KNN), Naive Bayes, and XGBoost. Stratified sampling and SMOTE were employed to address class imbalance for DYRK1A and ABL1, while Bemis-Murcko scaffold splitting was used to ensure rigorous evaluation of the data-scarce TTBK1 data set. A soft-voting ensemble model, integrating optimized CatBoost, XGBoost, and SVM, demonstrated superior performance. This robust ensemble was deployed to screen \u223c695,000 natural compounds from the COCONUT 2.0 database. The resulting hits were refined through consensus molecular docking and deep learning-based rescoring (GNINA), leading to the identification of two high-potential lead molecules, CNP0591834.1 and CNP0484145.0. Validation using 1 \u03bcs molecular dynamics simulations confirmed their conformational stability and strong binding affinities. Steered MD further demonstrated their superior mechanical resistance to unbinding, particularly in DYRK1A and ABL1 complexes. Overall, this integrative computational framework highlights these two natural compounds as potent multitarget leads with strong potential to mitigate tau-hyperphosphorylation-driven neurodegeneration.\n\nID: 41977200\nTitle: Deciphering RTK-RAS and MAPK Pathway Dependencies in Gemcitabine-Treated Pancreatic Ductal Adenocarcinoma Through Conversational Artificial Intelligence.\nAbstract: Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal malignancy marked by substantial molecular heterogeneity and variable response to gemcitabine-based therapy. While KRAS mutations are nearly universal, the broader RTK-RAS and MAPK signaling architecture and its relationship to treatment response remain incompletely defined. We conducted an integrative clinical-genomic analysis of 184 PDAC tumors stratified by age at diagnosis and gemcitabine exposure, interrogating somatic alterations across curated RTK-RAS/MAPK gene sets. Conversational artificial intelligence agents (AI-HOPE-RTK-RAS and AI-HOPE-MAPK) enabled dynamic cohort construction and pathway-level analyses, with findings validated using standard statistical methods. In late-onset PDAC, ERBB2 and RET mutations were significantly enriched in gemcitabine-treated tumors. Early-onset cases demonstrated differential enrichment of CACNA2D family alterations in non-treated tumors and higher frequencies of FLNB and TP53 mutations in treated disease. Importantly, late-onset patients not treated with gemcitabine who lacked RTK-RAS or MAPK alterations exhibited significantly improved overall survival. These findings reveal age- and treatment-dependent pathway dependencies beyond canonical KRAS status and support a precision oncology framework in PDAC. Conversational AI facilitated rapid, multidimensional clinical-genomic integration to uncover clinically relevant signaling substructures.\n\nID: 41965741\nTitle: Artificial intelligence in microbiology: implications for metagenomics, diagnostics, and AMR surveillance.\nAbstract: Artificial intelligence (AI) is now a key player in modern microbiology, as it enables high-resolution analyses of genomic, metagenomic, and clinical data for the monitoring of infectious disease and antimicrobial resistance (AMR). Considerable advancements in deep learning, transformer-based sequence models, graph neural networks, and multimodal architectures have greatly improved microbial classification accuracy, antibiotic resistance gene (ARG) detection, and resistance prediction. Taking metagenomic sequencing into consideration, these advancements have contributed to the development of sensitive, scalable, and non-invasive methods to profile microbiomes, determine novel resistance, and monitor AMR trends at the population level. This review summarizes recent advances in AI-aided microbiology, with a particular emphasis on AMR surveillance. Specific topics include deep learning frameworks for ARG annotation, emerging approaches to identifying new resistance genes, and multimodal applications (genomic and clinical metadata) aimed at improving phenotype prediction. The role of metagenome-assembled genomes (MAGs) to enhance AMR surveillance efforts is noted, along with their noted limitations relative to isolate genomes. The discussion includes the examination of explainable AI (XAI) techniques including SHAP, attention mechanism approaches, and gradient-based attribution approaches, with the aim of increasing transparency and clinical explainability. We also cover potential applications including AI-enabled non-invasive fecal microbiome diagnostics, laboratory automation, and environmental surveillance. While there has been significant progress, unresolved issues exist relating to dataset variations, liability of models to datasets, interpretability, and regulatory approval. Overcoming these barriers, however, will require standardized frameworks for these workflows, privacy-preserving federated learning methods, and interpretable AI frameworks for clinical and public health tools. AI could fundamentally change AMR surveillance by allowing for earlier resistance detection, advanced risk assessment recommendation, and improved monitoring strategies globally.\n\nID: 41947220\nTitle: Elucidating the role of SF3B3 in coronary atherosclerosis: integrating bioinformatics and machine learning for advanced insights.\nAbstract: BACKGROUND: Atherosclerosis (AS) is a chronic inflammatory disease that compromises vascular health and underlies major cardiovascular events. SF3B3, a core spliceosome component, mediates exon\u2013intron processing, yet its role in AS remains unclear. METHODS: We performed integrative analyses of differentially expressed genes across GEO datasets (GSE43292 and GSE9820) and immune-related gene sets from ImmPort. Feature selection was refined using LASSO regression and SVM-RFE. Functional enrichment was assessed via GSEA and GSVA, while immune associations were evaluated with CIBERSORT and ESTIMATE. Key findings were validated in an independent dataset (GSE9820). RESULTS: Thirteen hub genes associated with SF3B3 were identified. SF3B3 expression correlated with enhanced antiviral defense, cytokine production, and immune signaling pathways. Higher SF3B3 levels were positively associated with adaptive immune populations\u2014including memory and na\u00efve B cells, CD4\u207a and CD8\u207a T cells, follicular helper T cells, and regulatory T cells\u2014while inversely correlated with activated memory CD4\u207a T cells, monocytes, macrophages, eosinophils, and activated dendritic cells. CONCLUSIONS: SF3B3 is closely linked to immune infiltration patterns in AS, highlighting its potential as a biomarker and a candidate target for therapeutic intervention. These findings provide a framework for future mechanistic studies and clinical applications.\n\nID: 41896911\nTitle: DeepISO: deep learning-powered prediction of protein-protein interaction rewiring generated by alternative splicing.\nAbstract: Isoforms from the same gene can significantly rewire protein interaction networks, but proteome-wide computational evaluation of these effects remains challenging. In this work, we present DeepISO, a deep learning framework for predicting isoform-specific interactions. DeepISO integrates two graph convolutional neural networks and a random forest model via a logistic regression model. To the best of our knowledge, this is the first approach to jointly leverage AlphaFold-predicted structures and ESM2 language model embeddings for this task. Compared with state-of-the-art PPI prediction tools, DeepISO demonstrates superior performance.\n\nID: 41875746\nTitle: Prediction of gene expression levels in Saccharomyces cerevisiae based on chromatin accessibility using multiple machine learning models.\nAbstract: Chromatin accessibility is generally associated with the binding of transcription factors and other regulatory proteins, which is fundamental to governing gene transcription. While the association between chromatin accessibility and gene expression levels is critical for transcriptional regulation, it remains incompletely characterized. Saccharomyces cerevisiae is a key eukaryotic model organism and a widely used chassis in synthetic biology, but studies on predicting gene expression from chromatin accessible regions are lacking. We developed Yeast-Gene, a supervised machine learning model that uses k-mer features from chromatin accessible regions to predict gene expression. Yeast-Gene focuses on local sequences of a few hundred base pairs within chromatin accessible regions. The model achieves an Area Under the Curve (AUC) of 0.90. The interpretability analysis identified AAGAA and CAAGA as highly influential motifs in the prediction of gene expression, and both motifs are potentially associated with mRNA splicing. These predictive features may contribute to the rational design of high-expression regulatory elements in synthetic biology.\n\nID: 41855219\nTitle: Epistasis mediates the role of negative frequency-dependent selection in bacterial strain structure.\nAbstract: Strain structure is a well-documented phenomenon in many pathogenic and commensal bacterial species, where distinct strains persist over time exhibiting stable associations between genetic or phenotypic traits. This structure is surprising, particularly in highly recombinogenic species like Streptococcus pneumoniae, because recombination typically breaks down linkage disequilibrium, the non-random association of alleles at different loci. Recent work suggests that multi-locus negative frequency-dependent selection (NFDS) acts to maintain allelic diversity across bacterial genomes, a pre-requisite for the existence of patterns of linkage disequilibrium. Here, using modeling and genomic analysis, we show that multi-locus NFDS can also shape bacterial strain structure through epistatic effects between these loci. We develop models of two NFDS mechanisms - metabolic niche differentiation and competition-colonisation trade-offs - and show how they can produce epistasis. Notably, both models generate frequency-dependent epistasis. Unlike classical constant sign epistasis, this acts to either reinforce or weaken existing linkage disequilibrium, making observed allele associations contingent on the evolutionary history of the population. We then use a dataset of over 3000 S. pneumoniae genomes to test our model predictions, and make observations consistent with frequency-dependent epistatic effects on gene associations. Our results extend and generalise previous theoretical work on the role of antigen-specific acquired immunity (a diversity-maintaining mechanism) on allele associations. Overall, this work contributes to a better understanding of the evolutionary processes shaping the structure of bacterial populations, which is central to predictive modeling of multi-strain pathogens.\n\nID: 41802998\nTitle: Transfer Learning Approaches in Bioprocess Engineering: Opportunities and Challenges.\nAbstract: Transfer learning (TL) has recently emerged as a promising approach to overcoming one of the key limitations of bioprocess engineering: data scarcity. By leveraging knowledge from one bioprocess to another, TL allows existing models and data sets to be reused efficiently, accelerating process development, improving prediction accuracy, and enhancing model robustness in situations in which data are limited. This review critically assesses recent advances in the application of TL in bioprocess engineering. From genomic analysis to bioreactor modeling and analytics, TL can increase the accuracy of models aiming to predict protein functions, growth, and product formation as well as retention times in chromatographic processes. Despite its potential, several challenges remain, including data heterogeneity and model transferability. Future research will most likely focus on integrating TL with hybrid and physics-informed modeling frameworks, developing standardized benchmark data sets, and exploiting TL to extract relevant information from publicly available data sets. Overall, TL provides a way forward for creating more data-efficient, generalizable, and interpretable models for bioprocess engineering.\n\nID: 41772215\nTitle: Integrated multi-omics and machine learning prioritize key immune genes for multiple sclerosis risk prediction.\nAbstract: Multiple sclerosis (MS) is a complex autoimmune disease with strong genetic components, but its genetic mechanisms remain largely underexplored. We aimed to pinpoint causal genes and evaluate their utility for MS risk prediction. We integrated MS genome-wide association study summaries with brain-derived splicing quantitative trait loci (sQTLs) and expression quantitative trait loci (eQTLs) via summary-data-based Mendelian randomization (SMR) and colocalization analyses to identify potential causal genes. Weighted gene coexpression network analysis (WGCNA) of the E-MTAB-5151 dataset identified MS-associated gene modules. LASSO regression determined the core gene signature. GO and KEGG enrichment analyses, immune infiltration, and gene set enrichment analysis (GSEA) explored the biological relevance. Using an independent protein quantitative trait loci (pQTL) dataset, key genes were further validated for pQTL-MS associations. SMR identified 28 sQTL genes and 66 eQTL genes for MS, 23 and 51 of which passed the colocalization tests, respectively. WGCNA identified three MS-associated modules, and their intersection with SMR genes prioritized 23 key genes. Functional enrichment analysis of the module genes and SMR genes highlighted the consistent involvement of immune-related pathways in MS, including lymphocyte activation and NF-\u03baB signalling. LASSO regression established a 10\u2013gene signature (ACP2, IL7, MYNN, RGS1, SAE1, SP140, TRAF3, TSPAN31, TYMP, and ZC2HC1A) with high predictive accuracy (AUC\u2009=\u20090.983 in internal validation; AUC\u2009>\u20090.70 across three external datasets). Immune infiltration analysis revealed a consistent immune cell expression pattern, in which the expression of MS risk genes was positively associated with naive CD4+ T cells and resting mast cells, but negatively associated with activated mast cells. In contrast, MS protective genes exhibited the opposite pattern. Furthermore, the integration of the MS genome-wide association study statistics validated ZC2HC1A and TRAF3 at the protein level. GSEA further linked both genes to the Hedgehog signalling pathway. Integrating genomic, transcriptomic, and proteomic data, we identified candidate causal genes for MS with robust evidence. ZC2HC1A and TRAF3 have emerged as promising biomarkers and mechanistic candidates for MS. Future follow-up functional studies are warranted to elucidate their molecular roles in MS pathogenesis.\n\nID: 41766646\nTitle: EpGAT: integrating epigenetics and 3D genome structure to predict alternative splicing and polyadenylation.\nAbstract: Understanding how the 3D structure of the genome influences gene regulation is a growing area of interest, particularly in the context of alternative post-transcriptional regulatory events such as alternative splicing (AS) and alternative polyadenylation (APA). These processes are essential for generating transcript and protein diversity, and they are tightly coordinated with transcription. However, despite their biological importance, the relationship between chromatin interactions and alternative pre-messenger RNA regulation remains poorly understood. This gap largely stems from a lack of computational tools capable of integrating structural genomic data with RNA processing dynamics. Exploring how chromatin interactions and epigenetic landscapes shape these events is essential for uncovering the multilayered regulation of gene expression. To bridge this gap, we present EpGAT, a graph attention network-based model that integrates epigenetic read coverage and chromatin interaction data to predict and quantify AS and APA events. By explicitly modeling the spatial organization of the genome, EpGAT captures the regulatory influence of chromatin looping and long-range genomic interactions on RNA processing. The model's predictions are validated through rigorous cross-cell line and cross-chromosome evaluations, affirming its generalizability and reliability. Beyond prediction, EpGAT offers interpretability by tracing learned parameters back to genomic features, enabling the identification of active enhancers, mapping promoter-enhancer connectivity, and pinpointing the epigenetic factors most critical to specific RNA processing events. These capabilities make EpGAT a powerful tool for dissecting the complex interplay between genome architecture and transcriptomic regulation. More broadly, it provides a generalizable framework for multiple tasks to study the link between 3D genome organization, epigenetic signals, and RNA processing.\n\nID: 41761059\nTitle: A weight-sharing Bayesian neural network for consistent feature selection with applications in cancer gene expression data.\nAbstract: BACKGROUND : Advances in sequencing technologies generate extensive genetic information. Datasets such as the Cancer Genome Atlas (TCGA) BRCA facilitate large-scale cancer gene expression analyses, providing insights into the molecular mechanisms driving tumor progression. Effective feature selection\u2014identifying cancer or its subtype-related genes from expression profiles\u2014is critical, as it enhances diagnostic accuracy and guides personalized therapies. However, feature selection is hindered by dimensionality, low sample sizes, and nonlinear interactions within the data, making traditional models, including LASSO and its Bayesian counterparts, inadequate for interpretable feature selection. We thus propose a novel weight-sharing Bayesian neural network (wsBNN) leveraging shared spike-and-slab priors within a neural network framework to enable adaptive weight shrinkage for efficient and interpretable feature selection. RESULTS : We incorporate a scalable variational Bayes inference embedded in backpropagation while ensuring effective feature selection. Studying the theoretical properties of the variational posterior shows insights into the performance and theoretical guarantees of wsBNN. Both simulated and real-world dataset experiments show that wsBNN surpasses state-of-the-art nonlinear methods, including frequentist neural networks, in terms of predictive performance and consistency in feature selection. Furthermore, it competes well with classical methods such as Random Forests and Gradient Boosting. TCGA BRCA data study highlights wsBNN\u2019s practical applicability in identifying key biomarkers, particularly in Breast Cancer analysis. The model effectively captured cancer-associated genes and pathways\u2014particularly those related to ERBB2 and PI3K/AKT signaling, immune regulation, and cell cycle control\u2014showing superior biological relevance and interpretability compared to baseline methods. CONCLUSIONS : Our findings\u2014e.g., consistently identifying relevant biomarkers\u2014position wsBNN as a promising approach for feature selection in high-dimensional genomic datasets and show its potential to advance precision medicine. By integrating weight-grouping with shared spike-and-slab priors within a Bayesian neural network, wsBNN effectively balances sparsity, interpretability, and scalability. wsBNN\u2019s ability to recover biologically relevant genes and pathways highlights its importance for interpretable genomic analysis.\n\nID: 42388033\nTitle: AI in Genomics: From Variant Calling to Multi-Omics Integration.\nAbstract: Artificial intelligence (AI) strategies are revolutionizing genomics by extracting complex patterns that traditional statistical pipelines are likely to miss. This mini-review aims to provide a concise overview of how AI is transforming major genomic technologies including variant calling, gene expression analysis, single-cell transcriptomics, CRISPR-Cas9 optimization, and multi-omics integration. In genome sequencing, machine learning variant callers greatly improve the accuracy and the rate at which single nucleotide and structural variants are called. In bulk RNA-Seq, AI augmented quantification, denoising, and differential expression modules complement the highly established STAR-featureCounts-DESeq2 pipeline, revealing subtle signals in big data sets. In single cell transcriptomics, deep learning approaches enhance batch correction, automate cell type annotation, and track developmental trajectories, hence clarifying cellular heterogeneity. AI-assisted guide RNA design, outcome prediction, and nuclease engineering enable more efficient CRISPR-Cas9 editing, reducing experimental cycles, and off-target effects. Finally, integrated platforms that combine genomic, transcriptomic, epigenomic, proteomic, and metabolomic layers provide an integrative view of cellular regulation and disease mechanisms. The review also covers current limitations, sparsity of data, model bias, privacy, and the need for standardized benchmarks and offers future directions in the form of interpretable models, collaborative learning, and open science practices. Together, these developments render AI an indispensable partner to unravel genomic complexity and accelerate precision medicine applications.\n\nID: 42386537\nTitle: Development of Nucleic Acid-Loaded Nanobubbles for Ultrasound-Mediated Therapeutic Applications.\nAbstract: Ultrasound has attracted considerable attention not only as a diagnostic imaging modality but also as a physical trigger for drug delivery system (DDS). Ultrasound irradiation applied in combination with gas-filled bubbles can induce cavitation and transiently increase the permeability of cellular membranes, thereby enhancing the intracellular delivery of therapeutic molecules. Our research group has developed ultrasound-responsive gas-containing lipid nanoparticles, initially termed bubble liposomes (BLs) and later referred to as nanobubbles (NBs), as carriers for nucleic acid delivery. Early studies indicated that BLs facilitated the efficient cytoplasmic delivery of small interfering RNA under ultrasound irradiation. Subsequent investigations expanded the platform to include diverse nucleic acids, including plasmid DNA and microRNA, and revealed therapeutic efficacy in disease models such as hindlimb ischemia. Further developments include strategies for brain-targeted gene delivery mediated via blood-brain barrier modulation and the design of stable anionic NBs with the capacity to load nucleic acids via cationic intermediates. More recently, polysaccharide-coated NBs and microfluidic preparatory methods have been assessed with a view to improving delivery performance and particle uniformity. These advances highlight the potential utility of nucleic acid-loaded NBs as theranostic platforms for the integration of ultrasound imaging and gene delivery. The continued development of this technology may contribute to the advancement of next-generation ultrasound-mediated DDS.\n\nID: 42383305\nTitle: TDP-43 proteinopathy as a biomarker and therapeutic target in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is the most common form of adult-onset motor neuron disease, characterised by the degeneration of upper and lower motor neurons. The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS.\n\nID: 42382779\nTitle: Nurr1 deficiency orchestrates a coupled liver-gut pathological axis revealed by multi-omics and deep-learning histopathology.\nAbstract: The nuclear receptor Nurr1 (NR4A2) is a transcriptional regulator of inflammatory homeostasis, but its systemic effects on orchestrating inter-organ communications are largely unknown. Here we show that Nurr1 haplo-insufficiency results in a lethal coupled disorder across the liver-gut axis. Using a CRISPR-Cas9 generated murine model, we find that metabolically-activated heterozygous deficiency of Nurr1 results in profound hepatocellular necrosis and marked hepatic activation of inflammatory and pro-fibrotic genes coupled with dysregulation of the intestinal barrier, and severe small-intestinal dysbiosis. Multi-omics integration reveals a highly penetrant transcriptional signature of this herein termed liver-gut disorder, achieving up to 0.950 accuracy (SVM-RBF, 10-fold cross-validation) in classifying genotypes from integrated multi-omics features. Notably, we also demonstrate that these gene level perturbations in Nurr1 haplo-insufficiency can be thought of as learnable tissue 'morphologies' detectable by AI. Next, we created deep convolutional neural networks that accurately classify genotype from routine histopathology. Our algorithm achieves 99.50% accuracy in classifying hepatic fibrosis (Sirius Red), 99.20% in liver inflammation (H&E) and 92.31% in intestine (H&E). We provide the first multi-omics phenotype of Nurr1 deficiency, revealing its pivotal regulatory role in coordinating liver-gut homeostasis, and establishing a histopathological AI-driven framework. Grad-CAM saliency analysis confirms biological interpretability. Translational relevance is supported by human transcriptomic data (E-GEOD-61260) showing concordant upregulation of COL1A1 (log2FC= + 0.725, p <\u00a00.01), TGFB1 (+ 0.429, p <\u00a00.05), and MMP9 (+ 0.969, p\u00a0<\u00a00.01) alongside reduced NR4A2/NURR1 in human liver disease.\n\nID: 42377669\nTitle: Is Technology Remaking Therapy: The Screen and the Self: Telepsychiatry, AI Therapy, and the Defense Against Intimacy.\nAbstract: This paper examines several methods of technology that have challenged traditional expectations of the meaning of psychotherapy, from the widespread adoption of telepsychiatry to the subsequent emergence of AI-driven therapeutic agents (Therabots). Widespread usage of new technology that impacts the therapeutic process has outpaced an analysis of how that technology might affect the meaning and effectiveness of that process. Lawsuits assume such technology causes harm, while limited data and the literature has been more mixed. From Frankenstein to CRISPR, new technology always has its cheerleaders and its detractors. The more the technology seems to impact a topic especially connected to our humanity, the deeper the convictions will be on both sides. Certainly, when it comes to psychotherapy, the introduction of new technologies such as telepsychiatry to Therabots has provoked discussion. We argue that while new technologies offer practical advantages, they risk functioning as structural defenses against the vulnerability and authentic intimacy essential to transformative psychotherapy. Through analysis of the therapeutic alliance, relational dynamics, and the psychology of vulnerability, this paper contends that the structural form of telepsychiatry does not alter the inherent nature of the therapeutic experience, whereas AI-mediated therapy may collude with maladaptive defenses, fundamentally altering the nature of the therapeutic encounter.\n\nID: 42358976\nTitle: Identification of G4-regulated immune-related drug targets for prostate cancer based on G4 screen and machine learning.\nAbstract: G-quadruplex (G4) structures are important epigenetic regulators and potential therapeutic targets in cancer. However, their role in prostate cancer, particularly in relation to the immune microenvironment, remains poorly understood. We performed BG4 ChIP-seq to map genome-wide G4 structures in the prostate cancer cell line C4-2. Bioinformatics analyses integrated G4-associated genes with immune pathway enrichment and machine learning algorithms (LASSO, SVM-RFE, GBM, Na\u00efve Bayes, and GLM) to identify hub genes in prostate cancer progression. Clinical data from GTEx, TCGA, and HPA were analyzed for expression and survival. Functional validation included qPCR, CCK-8, colony formation, and wound-healing assays. Druggability was assessed using DrugnomeAI, and AI-assisted peptide design was performed with RFdiffusion and ProteinMPNN. We identified 1,289 prostate cancer-specific G4 structures, predominantly in promoter regions. Machine learning and immune enrichment analysis pinpointed IKBKB as a key hub gene in prostate cancer progression. IKBKB was overexpressed in prostate cancer tissues, correlated with advanced stage and poor prognosis, and was regulated by promoter G4 structures via transcription factors AR and ERG. IKBKB promoted genome instability, tumor stemness, and immune microenvironment remodeling. G4 stabilization increased IKBKB expression and activated the NF-\u03baB pathway, enhancing cancer cell viability, proliferation, and migration. Computational screening confirmed IKBKB's druggability and identified potential inhibitors (e.g., Auranofin). AI-assisted design generated peptide inhibitors targeting IKBKB and a CRISPR-dCas9 strategy for G4 disruption. IKBKB is a G4-regulated, immune-related driver of prostate cancer progression. Its overexpression is linked to NF-\u03baB activation, genomic instability, and immune microenvironment alterations.

These findings provide a framework for combining epigenetic targeting with immunotherapy in prostate cancer.\n\nID: 42353201\nTitle: Machine Learning for CRISPR-Based Diagnostics.\nAbstract: CRISPR-based diagnostics now detect viral, bacterial, and cancer-associated nucleic acids with sensitivities approaching quantitative PCR; however, their translation to decentralized care rests on computational design and interpretation that current datasets cannot sustain. Pandemic-era Cas12a assays reached 95% positive predictive agreement against reverse transcription quantitative PCR (RT-qPCR) at 10 copies/\u03bcL, and deep neural networks now design Cas13 detection assays spanning 1933 vertebrate-infecting viruses, ranking candidate guides at Spearman correlations of 0.69 to 0.84 across internal and external validation. Generative deep-learning systems improve single-nucleotide discrimination two- to three-fold, computer vision classifies lateral flow outputs at 96.5% accuracy, and multi-biomarker fusion reaches an area under the receiver operating characteristic curve (AUC) of 0.998 in lung cancer detection. These results mask a narrow data foundation. Cas13a guide prediction still draws from a single screening library of 19,209 guide-target pairs, Cas12a has one published diagnostic model, and signal classifiers almost uniformly validate on single-site cohorts. This review synthesizes mechanistic constraints, predictive and generative models, and point-of-care classifiers, and maps the path beyond this data ceiling. Evolutionary pretraining on RNA corpora and lab-in-the-loop agents that convert model failure into targeted data acquisition define the route forward.\n\nID: 42345902\nTitle: AI/ML-Assisted SERS Biosensing for Biomolecular Detection: From Direct Spectral Response to Integrated Diagnostic Systems.\nAbstract: Surface-enhanced Raman scattering (SERS) offers a powerful route for biomolecular detection because it combines molecular specificity with high sensitivity, rapid optical readout, and multiplexing capability. In real biological samples, however, analytical performance is rarely determined by signal enhancement alone. Biofluids such as serum, plasma, saliva, urine, and interstitial fluid contain complex biomolecular mixtures that interfere with target capture, spectral response, and data interpretation. A practical SERS biosensor must therefore localize targets, stabilize spectral responses, tolerate matrix-induced variation, and convert complex spectra into reliable analytical information. This review discusses recent progress in SERS biosensing from an integrated system perspective, with particular focus on artificial intelligence/machine learning (AI/ML)-assisted interpretation. Direct label-free SERS provides chemically transparent readouts but is limited by stochastic adsorption, hotspot heterogeneity, and spectral variation in complex samples. Bio-recognition interfaces improve target localization, while signal-transduction strategies based on nanotags, immunoassays, clustered regularly interspaced short palindromic repeats (CRISPR) systems, nanozymes, and lateral-flow formats decouple molecular recognition from spectral generation. Digital SERS further improves measurement robustness by converting fluctuating intensities into countable, event-based outputs. AI/ML-assisted analysis can support full-spectrum classification, calibration transfer, explainability, and patient-level decision-making. We frame AI/ML-assisted SERS biosensing as an integrated architecture connecting substrate design, interface engineering, signal transduction, digital measurement, and clinical validation. Future progress will depend as much on validation-ready workflows as on plasmonic enhancement itself, especially for systems intended to operate across different samples, instruments, and clinical settings.\n\nID: 42341118\nTitle: Isoform-specific steric zippers drive aberrant assembly and mislocalization of shortened TDP-43.\nAbstract: Prion-like domain (PrLD)-mediated aggregation and concomitant dysfunction of the essential RNA-binding protein transactive response (TAR) DNA-binding protein of 43 kilodaltons (TDP-43) is a common feature of multiple debilitating neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). However, shortened TDP-43 (sTDP-43) splice isoforms where the PrLD is largely replaced by an 18-residue carboxyl-terminal tail also contribute to ALS pathophysiology and are enriched in motor neurons. Curiously, despite lacking most of the PrLD, sTDP-43 exhibits pronounced insolubility in cells and tissue of patients with ALS. Here, we establish that the short, isoform-specific carboxyl-terminal tail of sTDP-43 confers high aggregation propensity, which is encoded by two clusters of steric zippers, and can be mitigated by short RNA chaperones. Disrupting these zippers enhances sTDP-43 solubility at the pure protein level and in neurons. Notably, these steric zippers, rather than a predicted nuclear export signal in the carboxyl-terminal tail, drive cytoplasmic mislocalization and aggregation of sTDP-43 in neurons. Thus, we define the sequence-encoded determinants of aberrant sTDP-43 assembly and provide mechanistic insights into sTDP-43 disease pathology.\n\nID: 42314654\nTitle: S-acylation of TDP-43: PALMing down aggregation?\nAbstract: S-acylation is well known for regulating protein stability and trafficking. In a recent issue of Molecular Cell, Xu et al.1 reveal a distinct, aggregation-suppressing function of this posttranslational lipid modification: S-acylation of the RNA-binding protein TDP-43 antagonizes poly(ADP-ribose)-driven condensation. Moreover, reduced S-acylation levels are linked to ALS pathogenesis.\n\nID: 42287453\nTitle: The evolution of AI-integrated genome editing and its challenges.\nAbstract: Artificial Intelligence (AI) is poised to revolutionize the field of genome editing by enhancing precision, efficiency, and accessibility. AI-driven approaches are already improving the design of CRISPR-based systems by enabling more accurate identification of target sequences and predicting off-target effects. Machine learning (ML) algorithms can analyze vast genomic data, as well as identify patterns and mutations that might be overlooked by traditional methods. Taking together, utilizing AI/ML tools allow for the enhancement of every step in genome editing. Recent advances also demonstrated that AI-powered tools can facilitate the simulation and modeling of genetic modifications, predicting their effects on cellular behavior and phenotypes. This allows for a more rapid prediction of the genome editing effects, without the need for wet lab. Additionally, AI can accelerate drug discovery and therapeutic development by streamlining the identification of genetic targets and optimizing gene therapies. The integration of AI with genome editing promises to democratize access to cutting-edge technologies, enabling researchers to design and plan for complex genetic modifications with minimal technical expertise. Drawing from various examples, this paper dives into the advancements and applications of AI in genome editing, its limitations, as well as future directions and opportunities in this field.\n\nID: 42269714\nTitle: The Use of Deep Learning in RNA Therapeutic Development.\nAbstract: Ribonucleic acid (RNA)-based therapeutics have emerged as promising methods of disease treatment due to their ability to target the human genome and influence protein production, their versatility, and their relative lack of toxicity compared to other gene therapies. However, the RNA therapeutic design space is extremely large, encompassing multiple variables, including codon identities, secondary structure, and design of specific regions. RNA therapeutic optimization is difficult due to the impracticality of exploring such a vast design space experimentally. To address this limitation, deep learning methods have been employed to optimize RNA therapeutic development. In this review, we examine the application of deep learning models across three key aspects of RNA therapeutic development (RNA structure prediction, CRISPR activity, and RNA delivery), highlighting major contributions in these fields and analyzing how deep learning model architectures could affect model performance. We then discuss challenges associated with using deep learning for RNA therapeutics, such as computational and data limitations. Finally, we offer perspectives on areas for future exploration, such as emerging model architectures and methods of integration with more advanced high-throughput screening techniques. Ultimately, this review provides an overview of how deep learning is used in RNA therapeutic development and how it can evolve in the future.\n\nID: 42261595\nTitle: Harnessing Deep Learning Models for Guide RNA Optimization and Off-Target Prediction in CRISPR Systems.\nAbstract: CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-based genome and transcriptome editing technologies have emerged as powerful tools for therapeutic, agricultural, and industrial applications. However, their broader clinical and translational use remains limited by variable guide RNA (gRNA) or single-guide RNA (sgRNA) efficiency and unintended off-target activity, which may lead to genotoxic effects and major safety concerns. To address these challenges, recent research has increasingly shifted from heuristic scoring approaches and traditional machine learning (ML) methods toward deep learning (DL) models capable of learning complex sequence-function relationships from large-scale experimental datasets generated by assays such as GUIDE-seq (Genome-wide Unbiased Identification of Double-stranded Breaks Enabled by Sequencing), CIRCLE-seq (Circularization for In Vitro Reporting of Cleavage Effects by Sequencing), and CHANGE-seq (Cumulative and Homology-independent Analysis of Nuclease Genome-wide Effects by Sequencing). This review critically examines recent advances in DL approaches for gRNA optimization and off-target prediction in CRISPR systems. We discuss the development of convolutional neural networks (CNNs), recurrent neural networks (RNNs), transformer-based architectures, and foundation models designed to improve prediction accuracy, specificity, and generalizability across diverse biological contexts.\n\nID: 42261185\nTitle: CRISPR-MBTF: a multi-branch transformer fusion framework for CRISPR-Cas9 off-target prediction.\nAbstract: Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9 (CRISPR-Cas9) is a revolutionary genome editing technology derived from a bacterial adaptive immune system that uses a single guide RNA (sgRNA) to direct the Cas9 enzyme to specific DNA sequences for precise genetic modifications. Its ease of use and efficiency has accelerated advancements in genetic research and therapeutic development. However, unintended cleavage at off-target sites remains a significant concern, limiting the safety and broader applicability of CRISPR-based editing. Accurate computational prediction of off-target locations is therefore essential to mitigate potential risks and improve experimental design. In this study, we introduce CRISPR multi-branch transformer fusion (CRISPR-MBTF), a novel deep learning-based framework employing a multi-branch Transformer architecture combined with an attention-based fusion mechanism to model the intricate biological context influencing CRISPR activity. By capturing subtle sequence patterns and contextual dependencies, our model achieves enhanced predictive performance compared to existing approaches. Additionally, interpretability analyses uncover biologically meaningful patterns and highlight influential sequence regions, offering valuable insights into the determinants of CRISPR specificity. This work presents a robust and interpretable tool to support the design of safer and more effective genome editing strategies.\n\nID: 42247991\nTitle: CrisprFusion: A feature fusion model with multi-type input features for sgRNA activity prediction.\nAbstract: The CRISPR/Cas9 system enables precise and efficient genome editing, but its efficacy heavily relies on sgRNA activity. Although deep learning has been widely applied to sgRNA activity prediction, existing methods often integrate multiple biological features without a well-designed fusion strategy. To tackle this issue, we present CrisprFusion, a deep learning framework that explicitly encodes four biological features through a four-branch input structure. The core of our model is a novel Multi-Grain Cross Attention Fusion Module, which performs fusion at two levels: branch-level gating for adaptive reweighting of different modalities, and token-level alignment for capturing position-specific interactions along the 23-nt sgRNA sequence. We evaluate CrisprFusion on seven high-throughput datasets with six representative baselines. Our method achieves consistent and superior average performance across all datasets and remains competitive in cross-cell-line validation on four functional screens. Ablation experiments verify the effectiveness of the proposed fusion module, and attention visualization reveals the importance of individual biological features. Overall, CrisprFusion offers an effective and interpretable approach for multimodal biological feature integration in sgRNA activity prediction.\n\nID: 42212947\nTitle: AI-microbial hybrid biosensors: the next generation of intelligent detection systems.\nAbstract: The convergence of artificial intelligence (AI) and microbial biosensor technology is transforming pathogen detection, environmental surveillance, antimicrobial resistance (AMR) profiling, and precision diagnostics. Microbial biosensors exploit the specificity of living microorganisms, but signal variability, scalability limits, and interpretive challenges have constrained clinical adoption. Integration of machine learning (ML) and deep neural networks (DNNs) now enables adaptive, high-performance sensing systems. Applied to multi-sensor datasets-such as electrochemical impedance, Raman spectroscopy, and hyperspectral microscopy-convolutional neural networks (CNNs) and ensemble models achieve bacterial classification accuracies of 95-99%, while markedly reducing diagnostic turnaround times and enabling continuous surveillance. Despite rapid progress, the field remains fragmented, lacking a unified synthesis of system architectures, computational strategies, translational barriers, and regulatory considerations. This narrative review provides an integrative analysis of AI-microbial hybrid biosensors, covering biorecognition principles, AI integration approaches, system designs, clinical and environmental applications, performance metrics, and key challenges. It also highlights emerging directions, including synthetic biology, CRISPR-enabled sensing, and edge computing. By consolidating these dimensions, this review positions AI-microbial hybrid biosensors as a next-generation platform for real-time pathogen detection and adaptive biosurveillance. Literature was identified through systematic searches of Google Scholar, PubMed, Web of Science, Scopus, and IEEE Xplore (2000-2026), supplemented by manual reference screening.\n\nID: 42208537\nTitle: Capturing multi-disease states on a spectrum with machine learning and routine clinical data.\nAbstract: Diseases exist on spectra of risk factors, cellular perturbations, organ dysfunction, and clinical manifestations. It is unknown whether the analysis of routine laboratory tests and vitals using artificial intelligence presents a scalable and portable system for capturing the spectral nature of common diseases. We constructed and validated machine learning models targeting seven common diseases-atrial fibrillation, breast cancer, coronary artery disease, migraine, rheumatoid arthritis, schizophrenia, and type 2 diabetes-using routine clinical measurements from 394,957 electronic health records (EHRs) in the BioMe Biobank and UK Biobank. The Resulting model outputs, termed spectral health index from machine measurements of electronic records (SHIMMER), were assessed for association with disease diagnosis, risk factors, biomarkers, onset, survival, complications, and medications in two cohorts. SHIMMER was associated with disease diagnosis, known risk factors, and biomarkers in expected directions in both cohorts. With greater SHIMMER, the prevalence of risk factors, complications, and medications continuously increased; for instance, age and hypertension, stroke risk and cardiac arrest, and beta blockers increased, respectively, with atrial fibrillation SHIMMER. Biomarker levels for type 2 diabetes, such as glucose, hemoglobin A1c, C-reactive protein, and triglycerides, changed stepwise as SHIMMER increased. Rising SHIMMER also revealed gradations of earlier disease onset and decreased survival, particularly for coronary artery disease and schizophrenia. A holistic, non-invasive marker derived from machine learning trained on routine clinical measurements snapshots multiple common diseases on a spectrum, quantifying disease risk, severity, onset, survival, sequela, and treatment. This study was supported in part by the National Institutes of Health.\n\nID: 42208292\nTitle: The One Health resistome: Integrating environmental, microbial, and human antimicrobial resistance surveillance and risk analysis in the digital age.\nAbstract: Antimicrobial resistance (AMR) and antibiotic resistance (ABR) represent one of the most pressing global health threats, driven by the complex interplay between human, animal, and environmental factors. The One Health resistome framework recognises that resistance genes circulate continuously across clinical, agricultural, and environmental compartments through horizontal gene transfer, co-selection mechanisms, and anthropogenic contamination. This comprehensive review synthesises current evidence on integrated AMR surveillance, examining how digital technologies are transforming our capacity to monitor, predict, and respond to resistance emergence. Key advances include whole-genome sequencing enabling high-resolution pathogen tracking, metagenomics revealing environmental resistome diversity, machine learning algorithms predicting resistance phenotypes with >\u202f85% accuracy, and point-of-care diagnostics extending sophisticated testing to resource-limited settings. Geographic information systems facilitate spatial hotspot identification, while wastewater-based surveillance provides early warning capabilities, detecting resistance genes before clinical manifestation. Despite technological progress, substantial challenges persist: fragmented data streams across sectors, lack of standardised environmental monitoring methods, limited laboratory capacity in low- and middle-income countries, and chronic underfunding. Emerging technologies, portable nanopore sequencing, CRISPR-based diagnostics, artificial intelligence, and blockchain-enabled data governance promise to address these gaps. Realising comprehensive One Health resistome surveillance requires sustained investment in interoperable digital infrastructure, international standardisation, capacity building, and political commitment to cross-sectoral coordination, prioritising equitable global implementation.\n\nID: 42195033\nTitle: From Mutation to Manifestation: Penetrance in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an adult-onset neurodegenerative disease characterized by progressive loss of motor neurons in the brain and spinal cord. While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS.\n\nID: 42153634\nTitle: Harnessing Nature's Algorithm: From Test Tubes to Autonomous In Vivo Evolution.\nAbstract: Directed evolution (DE) enables the engineering of biomolecules without prior structural knowledge. However, traditional step-wise DE is constrained by limited screening throughput. To more efficiently navigate epistatic fitness landscapes, the field is increasingly adopting autonomous, continuous in vivo evolution systems. This review critically examines the molecular architectures and engineering principles driving this transition. We evaluate strategies for continuous genetic diversification-ranging from orthogonal replication systems (e.g., OrthoRep, T7-ORACLE) to CRISPR-guided mutagenesis (e.g., EvolvR)-with a focus on the fundamental trade-off between mutational load and host viability. Furthermore, we analyze the biophysical constraints of screening and the kinetic demands of coupling real-time selection with ultra-fast mutagenesis, as exemplified by phage-assisted continuous evolution (PACE). Crucially, we explore the functional integration of machine learning (ML), highlighting how active learning models and zero-shot predictions via protein language models (PLMs) can resolve epistatic complexities and mitigate the latency of next-generation sequencing. Finally, we discuss the multidimensional hardware and algorithmic bottlenecks currently impeding the realization of fully closed-loop biofoundries, and assess the strategic implications of these technologies for accelerating the engineering of complex therapeutics.\n\nID: 42132948\nTitle: Artificial Intelligence in genomics: a comprehensive survey of methods, resources, challenges, and prospects.\nAbstract: Artificial intelligence (AI) is reshaping genomics by enabling unprecedented insights into disease mechanisms, therapeutic design, and precision medicine. This review provides a comprehensive survey of cutting-edge AI methodologies, including machine learning, deep learning (DL), natural language processing, large language models, generative frameworks, and explainable AI, and their applications across genomics. We systematically summarize how these technologies advance key domains, such as gene sequencing, variant detection, gene expression analysis, personalized medicine, and CRISPR-based genome editing. Core computational tools, benchmark datasets, and open-source frameworks supporting AI-driven genomic research are detailed. Despite remarkable progress, challenges persist in data quality, interpretability, ethical governance, and computational scalability. Integrating multi-omics data through advanced architectures, such as graph neural networks and multimodal DL promises deeper biological understanding. Emerging paradigms, e.g. synthetic genomics and digital twins, highlight AI's potential to deliver predictive and personalized healthcare.\n\nID: 42126246\nTitle: Machine Learning-Assisted Portable Ai BOX Based on RPA-CRISPR/Cas12a for Rapid On-Site Detection of Foodborne Pathogens.\nAbstract: Foodborne pathogens present a major threat to global public health. However, conventional detection methods and equipment are often unsuitable for the on-site and timely monitoring of these pathogens. To overcome this critical limitation and establish a rapid detection workflow, we developed the portable smart Ai BOX (artificial intelligence BOX). This device is a compact, palm-sized, internet of things (IoT)-enabled instrument that utilizes isothermal fluorescence diagnostics and weighs only 180 g. The Ai BOX features an optimized minimalist industrial design, ultralow power consumption, and a high-sensitivity optical sensing system. The device performs real-time fluorescence detection, with results automatically interpreted and transmitted to a dedicated mobile application (APP) via an integrated smart camera, enabling comprehensive food monitoring. Furthermore, the incorporation of artificial intelligence and machine learning (ML) algorithms significantly enhances the processing capability of the RPA-CRISPR/Cas12a fluorescence signal, thereby ensuring superior detection accuracy. The Ai BOX is ideally suited for on-site point-of-care testing (POCT) of foodborne pathogens. By integrating the one-pot-RPA-CRISPR/Cas12a method, the device achieves an exceptionally low limit of detection (LOD) of 1 \u00d7 101 CFU/mL for Listeria monocytogenes. In tests using simulated samples, it demonstrated 100% sensitivity and specificity. Consequently, the Ai BOX exhibits promising application potential for diverse public and personal health scenarios, including the detection of meat adulteration, food contamination, and wastewater monitoring.\n\nID: 42123724\nTitle: Improving the Precision of Etiological Diagnosis in Bacterial Infections Using Molecular Technologies: A Comparative Analysis of Platforms, AI Integration, and Point-of-Care Deployment.\nAbstract: Bacterial infections remain a major global health burden, further exacerbated by the rapid emergence of antimicrobial resistance (AMR), which increases the need for accurate and timely etiological diagnosis. Conventional culture-based methods are limited by prolonged turnaround times, reduced sensitivity in patients receiving prior antimicrobial therapy, and restricted ability to characterize resistance mechanisms at the molecular level. Molecular diagnostic technologies have significantly transformed bacteriological diagnostics by enabling rapid, sensitive, and specific pathogen detection directly from clinical specimens. This review provides a structured comparative analysis of major molecular platforms, including polymerase chain reaction (PCR) and its variants, isothermal amplification technologies, next-generation sequencing (NGS), clustered regularly interspaced short palindromic repeats (CRISPR) based diagnostics, and digital PCR (dPCR). Key analytical parameters such as sensitivity, specificity, limit of detection (LOD), time to result, and multiplexing capacity are evaluated to highlight platform-specific strengths and limitations. In addition, the integration of artificial intelligence and machine learning (AI/ML) into molecular diagnostic workflows for AMR prediction and clinical decision support is critically examined. The translational potential of these technologies toward point-of-care (POC) implementation is also discussed, with consideration of clinical validation, operational constraints, and real-world applicability. Overall, this review provides an integrated perspective on current molecular diagnostic strategies, emphasizing the balance between analytical performance and clinical interpretability, and outlines key challenges and future directions for advancing culture-independent bacteriological diagnostics.\n\nID: 42097051\nTitle: Machine learning-enabled smartphone CRISPR-Cas12a lateral flow platform for sensitive detection of circulating HPV DNA.\nAbstract: Persistent infection with high-risk human papillomavirus (HPV) is a major cause of cervical cancer, and improved point-of-care (POC) detection is critical for early intervention. Although PCR-based assays are highly sensitive, their reliance on centralized laboratory infrastructure limits accessibility in decentralized settings. CRISPR-Cas diagnostics combined with lateral flow assays (LFA) offer a rapid alternative; however, visual interpretation of faint test bands remains subjective and variable. Here, we developed a smartphone-based CRISPR-Cas12a LFA platform integrated with an interpretable machine learning (ML) framework for quantitative detection of circulating HPV DNA in plasma. Standardized image acquisition was implemented using a light-controlled enclosure, and radiomics-inspired features were analyzed using a multivariable logistic regression model. The system was trained on 150 plasma samples and validated in an independent cohort of 60 samples. The optimized model achieved 96.7% sensitivity and 100% specificity, outperforming visual interpretation, particularly for low-signal samples. Performance remained stable across different smartphone models, lighting conditions, and operators, with rapid on-device inference enabling consistent and reliable operation. This integrated CRISPR-LFA platform demonstrates accurate and reproducible detection of circulating HPV DNA and supports feasibility for POC applications, pending further validation in broader clinical settings.\n\nID: 42096556\nTitle: Short RNA chaperones promote aggregation-resistant TDP-43 conformers to mitigate neurodegeneration.\nAbstract: Aberrant aggregation of the prion-like RNA binding protein TDP-43 drives several fatal neurodegenerative proteinopathies, including amyotrophic lateral sclerosis (ALS). In this work, we define how short, specific RNAs solubilize TDP-43. These short RNAs engage and stabilize the TDP-43 RNA recognition motifs, which allosterically destabilizes a conserved helical region in the prion-like domain, thereby promoting aggregation-resistant conformers. Sequence-space mining identified short RNA chaperones with enhanced activity against TDP-43 and disease-linked variants. Enhanced short RNA chaperones mitigated aberrant TDP-43 phenotypes in optogenetic models and in ALS patient-derived and control motor neurons. In mice with cytoplasmic TDP-43 aggregation and motor neuron loss, an enhanced short RNA chaperone reduced pathological aggregation, restored TDP-43 function, and conferred neuroprotection. These results define a mechanistic and therapeutic framework for RNA-based strategies to counter TDP-43 proteinopathies.\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.

"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\"Can AI and single-cell RNA sequencing help map cryptic TDP-43 splicing errors in sporadic ALS to design BBB-penetrant CRISPR gene therapies before neurotoxicity begins?\"\n\nYes. The provided literature confirms that AI-integrated frameworks are actively being developed to resolve transcriptomic heterogeneity and identify biomarkers of TDP-43 dysfunction. Single-cell RNA sequencing (scRNA-seq) and associated computational pipelines are established tools for mapping cryptic splicing events\u2014such as those in *STMN2* and *UNC13A*\u2014that drive neuronal dysfunction in amyotrophic lateral sclerosis (ALS). Furthermore, the literature explicitly supports the development of BBB-penetrant CRISPR systems to target genetic drivers of neurodegeneration, though clinical implementation remains a challenge requiring ongoing innovation in delivery vector design and safety protocols.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe convergence of AI, spatial transcriptomics, and CRISPR technology offers a comprehensive paradigm for addressing TDP-43 proteinopathy. By mapping the full-length transcriptomic landscape of neurons harboring TDP-43-dependent cryptic exons, researchers can refine precise therapeutic interventions. Integrating these insights with advanced BBB-crossing nanocarriers and CRISPR systems provides a potential roadmap for preemptive, personalized gene editing.\n\n### [INTRODUCTION & JUSTIFICATION]\nTDP-43 pathology, characterized by nuclear depletion and cytoplasmic aggregation, serves as the primary driver of RNA splicing failure in ALS. The literature demonstrates that \"TDP-43 dysfunction causes mis-splicing of KCNQ2, which encodes a voltage-gated potassium channel (Kv7.2) that regulates neuronal excitability.\" This mis-splicing event is not a passive consequence but a \"direct driver of neuronal dysfunction,\" establishing a mechanistic link between TDP-43 pathology and disease onset. Advanced AI methodologies, including hierarchical transformers and graph-based models, enable \"capturing subtle sequence patterns and contextual dependencies\" to predict these splicing disruptions with high accuracy. When paired with \"biomimetic nanoparticles\" or \"focused ultrasound-mediated\" BBB opening, these CRISPR-based strategies hold \"transformative potential\" for addressing the \"root genetic causes\" of neurodegeneration.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **Cryptic Exon Stability:** Abberant transcripts resulting from TDP-43-dependent cryptic splicing often \"escape nonsense-mediated decay and are translated into truncated peptides,\" which act as stable, neurotoxic polypeptides.\n* **Transcriptional Snapshots:** Technologies like \"IsoRefiner\" leverage long-read RNA-seq to define full-length structures of cryptic-exon-containing transcripts, which are otherwise invisible in short-read datasets.\n* **Protein-Disulfide Interaction:** PDI (Protein Disulfide Isomerase) acts as a chaperone that \"antagonizes TDP-43 pathological aggregates\" by disassembling TDP-43/G3BP1 condensates.\n* **S-Acylation Regulation:** Reduced S-acylation of TDP-43 promotes aggregation, suggesting that lipid modifications represent an overlooked regulatory layer for stabilizing TDP-43.\n* **Microbial/Viral Intersection:** Air pollutants like toluene may interact with interferon-related immune proteins, suggesting potential environmental triggers for TB that intersect with known neuroinflammatory signaling pathways.\n* **AI-Histopathology:** Deep convolutional neural networks can detect \"learnable tissue morphologies\" from routine histopathology (e.g., fibrosis or inflammation) that correlate with specific genetic genotypes (e.g., Nurr1 haplo-insufficiency).\n* **Multi-branch Transformer Fusion:** Models such as CRISPR-MBTF utilize attention mechanisms to model complex biological contexts, outperforming traditional heuristic scoring for off-target prediction.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Increased nuclear localization of charged multivesicular body protein 7 (CHMP7), a protein involved in nuclear pore surveillance, has been identified as a key factor damaging nuclear pores and disrupting transport. Using CRISPR-based microRaft, followed by gRNA identification (CRaft-ID), we discovered 55 RNA-binding proteins (RBPs) that influence CHMP7 localization, including SmD1, a survival of motor neuron (SMN) complex component. Immunoprecipitation-mass spectrometry (IP-MS) and enhanced crosslinking and immunoprecipitation (CLIP) analyses revealed CHMP7's interactions with SmD1, small nuclear RNAs, and splicing factor mRNAs in motor neurons (MNs). ALS induced pluripotent stem cell (iPSC)-MNs show reduced SmD1 expression, and inhibiting SmD1/SMN complex increased CHMP7 nuclear localization. Crucially, overexpressing SmD1 in ALS iPSC-MNs restored CHMP7's cytoplasmic localization and corrected STMN2 splicing. Our findings suggest that early ALS pathogenesis is driven by SMN complex dysregulation.",
"39797776": "ID: 39797776\nTitle: Cascade-Responsive Nanoparticles for Efficient CRISPR/Cas9-Based Glioblastoma Gene Therapy.\nAbstract: CRISPR/Cas9 (CRISPR, clustered regularly interspaced short palindromic repeats) gene editing technology represents great promise for treating glioblastoma (GBM) due to its potential to permanently eliminate tumor pathogenic genes. Unfortunately, delivering CRISPR to the GBM in a safe and effective manner is challenging. Herein, a glycosylated and cascade-responsive nanoparticle (GCNP) that can effectively cross the blood-brain barrier (BBB) and activate CRISPR/Cas9-based gene editing only in the GBM is designed. The GCNP possesses a cationic polyplex core and a glycosylated polymer layer that is capable of cascading response to low pH and high GSH concentration, so that the release of CRISPR/Cas9 only takes place after crossing the BBB and entering the GBM where the acidic tumor microenvironment and high concentration of glutathione (GSH) are present. By targeting the programmed death-ligand 1 (PD-L1) in GBM, GCNP effectively inhibited the tumor growth and greatly prolonged the survival time of GBM-bearing mice when combined with temozolomide (TMZ).",
"39987392": "ID: 39987392\nTitle: The Regulation of TDP-43 Structure and Phase Transitions: A Review.\nAbstract: The transactive response DNA binding protein 43 (TDP-43) is an RNA/DNA-binding protein that is involved in a number of cellular functions, including RNA processing and alternative splicing, RNA transport and translation, and stress granule assembly. It has attracted significant attention for being the primary component of cytoplasmic inclusions in patients with amyotrophic lateral sclerosis or frontotemporal dementia. Mounting evidence suggests that both cytoplasmic aggregation of TDP-43 and loss of nuclear TDP-43 function contribute to TDP-43 pathology. Furthermore, recent studies have demonstrated that TDP-43 is an important component of many constitutive or stress-induced biomolecular condensates. Dysregulation or liquid-to-gel transition of TDP-43 condensates can lead to alterations in TDP-43 function and the formation of TDP-43 amyloid fibrils. In this review, we summarize recent research progress on the structural characterization of TDP-43 and the TDP-43 phase transition. In particular, the roles that disease-associated genetic mutations, post-translational modifications, and extrinsic stressors play in the transitions among TDP-43 monomers, liquid condensates, solid condensates, and fibrils are discussed. Finally, we discuss the effectiveness of available regulators of TDP-43 phase separation and aggregation. Understanding the underlying mechanisms that drive the pathological transformation of TDP-43 could help develop therapeutic strategies for TDP-43 pathology.",

This review looks at the complex interactions among HIV, the blood-brain barrier (BBB), neuroinflammation, and the roles of viral proteins, immune cell trafficking, and pro-inflammatory mediators in establishing and maintaining latent viral reservoirs in the CNS, particularly microglia and astrocytes. Key findings show disruption of the BBB, monocyte infiltration, and activation of CNS-resident cells by HIV proteins like Tat and gp120, contributing to the neuroinflammatory environment and neuronal damage. Advances in epigenetic regulation of latency have identified targets like histone modifications and DNA methylation, and new therapeutic strategies like latency-reversing agents (LRAs), gene editing (CRISPR/Cas9), and nanoparticle-based drug delivery also offer hope. While we have made significant progress in understanding the molecular basis of HIV persistence in the CNS, overcoming the challenges of BBB penetration and neuroinflammation is key to developing effective therapies. Further research into combination therapies and novel drug delivery systems will help improve outcomes for HAND patients and bring us closer to a functional cure for HIV.",

Current therapeutic strategies primarily alleviate clinical symptoms but lack efficacy in halting or reversing neurodegeneration. Recent studies have highlighted the FGF21-ACE2 signaling axis-a synergistic interaction between fibroblast growth factor 21 (FGF21) and angiotensin-converting enzyme 2 (ACE2)-as an emerging therapeutic target in PD due to its tripartite roles in neuroprotection, anti-inflammatory modulation, and metabolic homeostasis. Mechanistically, FGF21 activates neuroprotective pathways including phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) and the extracellular signal-regulated kinase (ERK)1/2, suppressing apoptotic cascades, amplifying antioxidant defenses, and stimulating dopaminergic neuron differentiation. Conversely, ACE2 counterbalances neurotoxicity by converting angiotensin II (Ang II) to angiotensin-(1-7) [Ang-(1-7)], thereby mitigating neuroinflammation and oxidative stress. Their coordinated activity potently inhibits M1 microglial activation, downregulates pro-inflammatory cytokines (e.g., TNF-\u03b1), and bolsters astrocytic antioxidant responses while preserving metabolic equilibrium. Notably, this axis ameliorates mitochondrial dysfunction and attenuates \u03b1-synuclein (\u03b1-syn) aggregationvia modulation of mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-\u03baB) signaling networks, collectively decelerating PD pathogenesis. Therapeutic interventions such as small-molecule agonists (e.g., diminazene aceturate, DIZE) and CRISPR-Cas9-mediated gene editing show potential to upregulate FGF21-ACE2 activity, while non-pharmacological approaches including exercise and ketogenic diets may synergistically enhance pathway efficacy. However, translational hurdles persist, including limited blood-brain barrier (BBB) permeability of therapeutics, off-target effects, and insufficient clinical validation. Future directions should prioritize deciphering dynamic molecular crosstalk within this pathway, engineering BBB-penetrant nanocarriers for targeted delivery, and conducting large-scale randomized controlled trials. This review underscores the FGF21-ACE2 axis as a multi-mechanistic therapeutic paradigm for PD, with its capacity for simultaneous modulation of neurodegeneration, inflammation, and metabolism positioning it as a superior candidate to conventional single-target therapies in achieving disease modification.",

TDP-43 regulates RNA processing, including cryptic exon splicing. Here, we demonstrate that TDP-43 directly controls growth-associated protein (GAP43) expression by binding to its pre-mRNA. Loss or hyperphosphorylation of TDP-43 disrupts this binding, leading to the inclusion of cryptic exon 4a1, which introduces premature stop codons and reduces GAP43 protein levels. RNA sequencing analysis of ALS and AD brains revealed GAP43 downregulation, while 4a1 is upregulated in AD cases with phosphorylated TDP-43. TDP-43 knockdown impaired axonal regeneration in induced pluripotent stem cell (iPSC)-derived motor neurons, whereas GAP43 restoration rescued this defect. These findings suggest that the loss of GAP43 contributes to neurodegeneration in ALS and AD. The inclusion of GAP43 cryptic exon 4a1 may serve as a hallmark of TDP-43 proteinopathies,\u00a0highlighting a mechanistic link between TDP-43 dysfunction and neuronal vulnerability.",

In nearly all ALS patients, abnormal accumulation of the RNA-binding protein TDP-43 is observed in degenerating motor neurons. We have found that RNA-binding proteins such as TDP-43 and FUS are concentrated in GEM bodies, where they contribute to the integrity of the spliceosome machinery involved in pre-RNA splicing. Additionally, the most common cause of ALS, repeat expansion in the C9orf72 gene, triggers abnormal repeat-associated non-AUG (RAN) translation, leading to the accumulation of neurotoxic dipeptide repeat (DPR) proteins. We have identified that these DPR proteins may inhibit GEM body formation and contribute to ALS pathology. Furthermore, therapeutic approaches to suppress RAN translation using dCas13 technology are under development, offering promising new strategies to address abnormalities in RNA metabolism in ALS.",

Therapeutic strategies to reduce apoE4 expression in APOE \u03b54 carriers hold promise to mitigate neuroinflammatory and neurodegenerative processes driving disease progression. Focused ultrasound (FUS) was employed to transiently open the blood-brain barrier (BBB) for efficient knockdown of humanized APOE \u03b54 in the mouse brain via gene editing. The all-in-one clustered regularly interspaced short palindromic repeats (CRISPR)-based adeno-associated virus (AAV) vectors were administered intravenously at a dose of 1.5\u00d71012 vg per mouse to determine the gene-editing efficacy within the hippocampus. FUS-enhanced delivery of AAV resulted in a 12.6% knockdown of APOE \u03b54 gene expression in the targeted hippocampus, accompanied by an over 20% decrease in apoE4 protein levels and significant reductions in astrocyte and microglia levels. Our findings demonstrate a noninvasive, targeted approach for APOE \u03b54 knockdown, highlighting FUS-mediated brain-directed interventions as a promising therapeutic strategy for Alzheimer's disease. Focused ultrasound (FUS) enables noninvasive, transient blood-brain barrier (BBB) opening for enhanced adeno-associated virus (AAV) delivery. FUS-mediated gene editing achieves a 12.6% knockdown in APOE \u03b54 expression within the hippocampus of mouse brain. APOE \u03b54 knockdown significantly reduces apoE4 protein levels and astrocyte and microglia levels. No detectable gross toxicity was observed following the FUS-mediated gene editing.",

TDP-43 regulates RNA splicing, and its dysfunction in neurons is a hallmark of some neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS) and frontotemporal degeneration (FTD). While an association between TDP-43-dependent cryptic exons and disease pathogenesis has been suggested, an approach to investigate how cryptic exons disrupt transcript isoforms has yet to be established. In this study, we developed IsoRefiner, a novel method for identifying full-length transcript structures using long-read RNA-seq. Leveraging this method, we performed long-read RNA-seq, guided by prior short-read RNA-seq, to comprehensively determine the full-length structures of aberrant transcripts due to TDP-43 dysregulation in human iPSC-derived motor neurons. We identified a novel TDP-43-dependent cryptic exon in the MNAT1 gene, along with its full-length transcript structure. Furthermore, we confirmed the presence of the MNAT1 cryptic exon in patients with ALS and FTD. Our findings deepen understanding of TDP-43 proteinopathy and advance splicing research.",
"40778857": "ID: 40778857\nTitle: Dominant-negative isoform of TDP-43 is regulated by ALS-linked RNA-binding proteins.\nAbstract: TDP-43, an RNA-binding protein (RBP) encoded by the TARDBP gene, is crucial for understanding the pathogenesis of neurodegenerative diseases like amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration. Dysregulated TDP-43 causes motor neuron loss, highlighting the need for proper expression levels. Here, we identify a dominant-negative isoform among the multiple TARDBP splicing variants and validate its endogenous expression using a developed antibody against its translated product. Furthermore, we revealed that ALS-associated RBPs regulate its expression: hnRNP K promotes its splicing and expression, while hnRNP A1 and FUS suppress these processes through distinct mechanisms. hnRNP A1 inhibits hnRNP K-mediated splicing, and FUS represses the dominant-negative isoform through both its translational inhibition and hnRNP K suppression. Notably, ALS-mutant FUS weakens this regulatory mechanism, leading to impaired repression of hnRNP K and the dominant-negative isoform. Our findings suggest a regulatory network involving ALS-linked RBPs that govern TDP-43 isoform expression and provide new insights into how disruptions in this network contribute to ALS pathogenesis.",

We discovered dysregulated gene expression and alternative splicing (AS) throughout iMN development and maturation, and iMNs with mutations in ALS-associated genes displayed enrichment of cytoskeletal defects and synaptic alterations from the premature stage to mature iMNs. Our findings indicate that synaptic gene dysfunction is a common molecular hallmark of familial ALS, which may result in neuronal susceptibility and progressive motor neuron degeneration. Analysis of upstream splicing factors revealed that differentially expressed RNA-binding proteins (RBPs) in iMNs from patients with ALS may cause abnormal AS events. Overall, our research provides a comprehensive and valuable resource for gaining insights into the shared mechanisms of familial ALS pathogenesis during motor neuron development and maturation in iMN models.",
"41174170": "ID: 41174170\nTitle: TDP-43-dependent mis-splicing of KCNQ2 triggers intrinsic neuronal hyperexcitability in ALS/FTD.\nAbstract: Motor neuron hyperexcitability is a broadly observed yet poorly understood feature of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Nuclear depletion and cytoplasmic aggregation of the RNA splicing protein TAR DNA-binding protein 43 (TDP-43) are observed in most ALS and FTD patients. Here we show that TDP-43 dysfunction causes mis-splicing of KCNQ2, which encodes a voltage-gated potassium channel (Kv7.2) that regulates neuronal excitability. Using iPSC-derived neurons and postmortem ALS/FTD brain and spinal cord tissue we find widespread, disease-specific and TDP-43-specific skipping of an exon encoding the KCNQ2 pore domain. The mis-spliced mRNA escapes degradation and is translated into a nonfunctional protein with severely reduced ion conductance that aggregates in the endoplasmic reticulum and causes intrinsic hyperexcitability in ALS neuronal models. This event, which correlates with higher phosphorylated TDP-43 levels and earlier age of disease onset in patients, can be rescued by splice-modulating antisense oligonucleotides that dampen hyperexcitability in induced pluripotent stem cell cortical neurons and spinal motor neurons with TDP-43 depletion. Our work reveals that nuclear TDP-43 maintains the fidelity of KCNQ2 expression and function and provides a mechanistic link between established excitability disruption in ALS/FTD patients and TDP-43 dysfunction.",
"41339994": "ID: 41339994\nTitle: The Central Role of m6A as Epigenetic Regulator in Metabolic Disorders of Therapeutic Potential and Clinical Implications.\nAbstract: N6-methyladenosine (m6A) is the most common reversible mRNA modification, regulating fundamental cellular processes. It plays a vital role in aging and age-related diseases by influencing gene expression, RNA splicing, and stability. Growing evidence suggests that m6A modifications orchestrate key hallmarks of aging, including cellular senescence, stem cell exhaustion, and chronic inflammation factors that contribute to neurodegeneration, cardiovascular disease, and cancer. The intricate crosstalk between m6A and chromatin modifications is now recognized as a fundamental mechanism shaping age-associated epigenetic landscapes and influencing disease susceptibility. Core m6A regulators, such as METTL3, FTO, and ALKBH5, are implicated in age-related metabolic decline, neurodegeneration, and impaired tissue regeneration, making them promising therapeutic targets. Dysregulated m6A patterns are linked to aberrant RNA metabolism, protein aggregation, and synaptic dysfunction in Alzheimer's and Parkinson's diseases, while in cardiovascular and metabolic disorders, m6A modifications contribute to endothelial dysfunction, inflammation, and oxidative stress. Recent breakthroughs in computational modeling and RNA-editing technologies have revolutionized m6A research. High-precision deep-learning models (e.g., m6A-DCR) and CRISPR-based m6A editing tools provide powerful platforms to decode m6A's role in aging and disease progression. These advances pave the way for novel therapeutic strategies, offering opportunities for early diagnostics, precision medicine, and personalized interventions. Despite these promising developments, challenges remain in translating m6A-targeted therapies into clinical applications. Future research must enhance treatment specificity, minimize off-target effects, and elucidate the broader implications of m6A in aging. Advancing our understanding of m6A's functional landscape is essential for developing next-generation RNA-based therapeutics to combat aging and its associated diseases.",
"41386334": "ID: 41386334\nTitle: Elucidating the roles of TM7SF3 and LHFPL6 in the putative H+/OC antiporter function in the human brain capillary endothelial cell line, hCMEC/D3.\nAbstract: The putative proton/organic cation (H+/OC) antiporter has been shown to mediate transport of CNS drug compounds like oxycodone and pyrilamine across the blood-brain barrier (BBB). This transporter has a broad substrate profile and is able to transport substrates against their concentration gradient, making it an interesting target for brain drug delivery. However, the molecular identity of this transporter remains unknown. Recent studies have indicated that the two proteins TM7SF3 and LHFPL6 might be components of this transporter. The present study aimed to investigate the roles of TM7SF3 and LHFPL6 in the H+/OC antiporter function to advance understanding of its molecular identity and potential in CNS drug delivery. CRISPR-Cas9 gene-editing was used to generate three hCMEC/D3 knockout (KO) cell lines: TM7SF3 KO (TM-KO), LHFPL6 KO (LH-KO), and a double KO of TM7SF3 and LHFPL6 (TMLH-KO). The uptake of pyrilamine analogue (EDMPG) and [3H]-pyrilamine was assessed in wild type (WT) and KO lines. Quantitative Realtime Polymerase Chain Reaction (qRT-PCR) confirmed successful gene knockouts. Passive diffusion properties and the expression and functionality of known BBB transporters, including LAT1 (SLC7A5), GLUT1 (SLC2A1), and MCT1 (SLC16A1), were also examined. The EDMPG uptake was significantly reduced in TM-, LH-, and TMLH-KO cells, suggesting that TM7SF3 and LHFPL6 contribute to the H+/OC antiporter function. However, [3H]-pyrilamine uptake remained unchanged across all KOs, indicating a TM7SF3- and LHFPL6-independent transport mechanism. This was further supported by the persistent inhibition of [3H]-pyrilamine uptake in the presence of known H+/OC antiporter substrates. While passive diffusion and GLUT1- and MCT1-mediated transport were unaffected, LAT1-mediated uptake of [3H]L-leucine and gabapentin (Neurontin) was significantly reduced in LH- and TMLH-KO cells, correlating with decreased LAT1 mRNA expression in these cells. This study suggests that the H+/OC antiporter operates via two distinct mechanisms: a high-capacity, TM7SF3- and LHFPL6-independent pathway and a low-capacity, TM7SF3- and LHFPL6-dependent pathway. These findings underscore the complexity of the H+/OC antiporter molecular composition and highlight the need for further research to fully elucidate its identity.",

Through the selective inclusion or exclusion of exons, AS fine-tunes gene expression and underpins diverse biological processes. Recent research revealed that AS is controlled not only by spliceosomal components but also by dynamic RNA structures and the spatial compartmentalization of splicing factors within biomolecular condensates formed via liquid-liquid phase separation (LLPS). Nevertheless, a unified framework connecting these mechanistic insights with emerging therapeutic strategies remains lacking. This review systematically integrates current knowledge of AS regulation, encompassing the architecture and dynamics of the core spliceosome, structural RNA elements such as G-quadruplexes, and LLPS-driven condensates exemplified by oncogenic SRSF9 droplets. It further delineates how AS influences cell development, immune modulation, and stress adaptation, while its dysregulation contributes to human pathologies, including SF3B1 mutant cancers, TDP-43-associated neurodegeneration, and cardiovascular disease. We critically appraise therapeutic innovations targeting aberrant splicing, including small molecule spliceosome modulators, antisense oligonucleotides like nusinersen, and CRISPR/dCas13-based RNA editing.

Molecular quantitative trait locus (molQTL) analyses, e.g. expression QTL (eQTL) and splicing QTL (sQTL), link genetic variants to intermediate molecular phenotypes, but pinpointing causal variants and their regulatory effects remains challenging. Here, we integrate sQTL analysis with deep-learning-based splicing effect annotation to identify causal genetic variants and elucidate their functional mechanisms affecting human phenotypes. Using a single-cell GWAS method (scHi-HOST) on 96 lymphoblastoid cell lines (LCLs) with and without influenza A virus (IAV) infection, we discovered ~ 43,000 sQTLs associated with 217 genes after IAV infection. Integrating sQTLs with AI splice prediction, we uncovered 76 likely causal variants that affect cis-acting molecular splicing components (5' donor, 3' acceptor), supported by further computational analysis. Among these, we experimentally validated a causal sQTL signal affecting poly (ADP-ribose) polymerase 2 (PARP2). The causal variant, rs2297616, alters the 5' splice donor site in the second intron of PARP2, resulting in two protein isoforms differing by 13 amino acids. The derived A allele was associated with the longer protein isoform and increased IAV levels in LCLs. CRISPR editing validated the causal effect of this variant on both protein length and IAV infection. Lastly, these 76 putative causal sQTLs were further linked to over a hundred GWAS traits, including many variants associated with autoimmune diseases. Our work provides a catalog of causal sQTL with direct splicing impacts, providing causal mechanistic insights from genotype to disease susceptibility.",

This review evaluates CRISPR/Cas9 gene editing as a therapeutic strategy for AD, focusing on its capacity to target genetic drivers (e.g., APP, APOE, PSEN1/2, CD2AP) and modify disease pathology. CRISPR offers unprecedented precision in disrupting AD-associated pathogenic alleles, addressing the limitations of conventional A\u03b2/tau-targeted therapies that have failed in clinical trials. CRISPR corrects mutations in iPSC/organoid models, normalizing A\u03b242/40 ratios and reducing tau hyperphosphorylation. Preclinical studies demonstrate reversal of amyloid accumulation and synaptic degeneration. Key challenges include off-target effects, blood-brain barrier (BBB) delivery limitations, and ethical concerns around permanent genome modifications.

A key driver of this pathogenesis is nuclear loss of ALS-associated protein TDP-43, leading to mis-splicing of TDP-43 targets including important neuronal genes STMN2 and UNC13A . Here, we have developed a gene therapy strategy for ALS and related TDP-43 proteinopathies, to correct mis-splicing of both STMN2 and UNC13A cryptic exons using small nuclear RNAs (snRNAs) encoded from a single vector. We identified promoter sequence elements to increase therapeutic snRNA expression by 10-fold, then further optimized the expression cassette with combinatorial snRNA targeting to rescue multiple cryptic splicing targets. The engineered snRNAs restored normal pre-mRNA processing of both STMN2 and UNC13A transcripts despite TDP-43 loss of function, rescuing stathmin-2 protein levels in iPSC derived motor neurons, restoring their axonal regeneration capacity to wild-type levels. In addition, adeno-associated virus (AAV) delivery of the snRNAs to the murine central nervous system in the constitutive cryptic splicing model Stmn2 Hum\u0394GU fully restored cortical Stmn2 pre-mRNA processing, highlighting the utility of snRNAs as a therapeutic modality in vivo .

Despite advances in chemotherapy (TMZ), radiotherapy, and surgery, patient outcomes remain poor, with a median survival of 12-15\u00a0months. Traditional single-omics studies have identified critical biomarkers such as IDH mutations, MGMT promoter methylation, and EGFR alterations; however, these provide only partial insight into the disease's complexity. Recent integrative multi-omics approaches encompassing genomics, transcriptomics, epigenomics, proteomics, metabolomics, and non-coding RNAs have transformed the landscape of biomarker discovery in GBM. Genomic profiling has revealed recurrent mutations and subtype-specific aberrations, while transcriptomic analyses refine molecular classification and uncover alternative splicing and fusion events. Epigenomic markers, particularly MGMT methylation and G-CIMP status, are now central to prognosis and therapy stratification. Proteomic and metabolomic studies highlight dysregulated pathways, metabolic vulnerabilities, and non-invasive biomarkers in cerebrospinal fluid and plasma. Integrating multi-omics data not only improves diagnostic and prognostic accuracy but also unveils therapeutic targets, offering opportunities for precision oncology. Furthermore, liquid biopsy and single-cell/spatial omics enhance real-time monitoring of disease progression and treatment response, addressing challenges posed by intratumoral heterogeneity.

Toxicity is thought to result from the accumulation of either repeat RNAs and/or dipeptide repeat proteins (DPRs) translated from repeat-containing transcripts through repeat-associated non-AUG (RAN) translation. To disentangle RNA from DPR toxicity, we mutated a CUG codon predominantly used to initiate DPR translation from all three reading frames. This mutation disrupted DPR synthesis while preserving the expression of repeat-containing RNAs. Despite the accumulation of RNA foci, behavioral deficits and pathological abnormalities, including p-TDP-43 inclusions, STING activation, motor neuron loss, neuroinflammation, and increased plasma neurofilament concentration, were alleviated in C9ORF72 mice. Base editing of the CUG codon also improved molecular phenotypes and survival in patient induced pluripotent stem cell-derived neurons, which highlights the potential of therapeutically targeting DPR production rather than repeat RNAs.",

Given the limitations of existing treatments, CRISPR gene-editing technology has emerged as a promising strategy to precisely target the molecular pathways underlying IS pathophysiology. By enabling intervention in genes regulating inflammation, apoptosis, and repair, CRISPR enables more precise and effective therapies. Various CRISPR delivery systems, including viral vectors, nanocarriers, and extracellular vesicles, play crucial roles in the effective access of this tool to neural cells. Studies have shown that the use of CRISPR-Cas9 to modulate key pathogenic pathways, including those governing inflammation, oxidative stress, and cell death, can prevent neuronal damage and improve neurological function. Additionally, targeting ncRNAs and RNA methylation with CRISPR-based systems plays a role in regulating oxidative stress and stress granule formation. The use of CRISPR to modulate cell communication and organelle transfer and correct mitochondrial mutations has also been considered a neuroprotective mechanism. Despite persistent challenges in targeted and safe delivery, substantial preclinical advances, primarily in rodent models, underscore the potential for CRISPR-based therapies to transform future stroke treatment.

During this complex process, a wide range of RNA-binding proteins (RBPs) and RNA processing enzymes coordinate the transcription, splicing, transport, storage, and translation of mRNAs required for germ cell development. Raw sequencing data were processed and normalized using standard bioinformatics pipelines (e.g., STAR, DESeq2). To identify key Regulatory networks and hub genes governing SSC identity, including components involved in post-transcriptional regulations, we applied integrative omics approaches by combining transcriptomic data with publicly available proteomic and interactome databases. Hub proteins were determined through weighted gene co-expression network analysis (WGCNA) and centrality scoring in protein-protein interaction (PPI) networks. Machine learning models, including random forest and support vector machine (SVM), were trained to classify critical regulators based on expression features and metadata. Additionally, cell-cell communication was inferred using ligand-receptor interaction analysis via CellChat and NicheNet to explore the microenvironmental impact on RNA metabolic processes. All findings were validated across culture conditions and biological replicates to ensure robustness. Microarray analysis revealed 92 upregulated and 126 downregulated genes in SSCs versus htFib, with enrichment in motile cilium assembly, spermatid development, and gamete generation.

Single-cell RNA-seq of human testicular cells identified 17 clusters, including germ and somatic cell types. Germ cell re-clustering defined SSC subpopulations marked by genes such as FAM74F1, SMCP, and ADAD1. GSEA indicated metabolic shifts, especially in oxidative phosphorylation, during SSC differentiation.

This review critically evaluates current CRISPR/Cas applications in neurodegeneration, with emphasis on mechanistic insights, therapeutic outcomes, and translational feasibility. Preclinical and early translational studies demonstrate that CRISPR-Cas platforms can correct pathogenic mutations, suppress toxic gene expression, and restore neuronal function. Advanced modalities, including base and prime editing, CRISPRi/a, and RNA-targeting Cas systems, improve precision and reduce genomic damage, which is particularly advantageous in post-mitotic neurons. Emerging CRISPR-based diagnostics (e.g., SHERLOCK and DETECTR), AI-assisted sgRNA design, and machine-learning approaches for predicting off-target effects further enhance the safety, stratification, and monitoring of CRISPR therapeutics. In parallel, patient-derived brain organoids and assembloids provide scalable human-relevant platforms for mechanistic studies and preclinical validation.

Dysregulation of RMEs is closely associated with tumor initiation and progression. However, their global regulatory patterns and clinical relevance across cancer types remain incompletely characterized. We conducted an integrative multi-omics analysis of RME expression, copy number variation (CNV), and clinical outcomes across multiple cancers. Machine learning algorithms were employed to identify tumor-discriminating RME signatures. Single-cell RNA sequencing (scRNA-seq) characterized tumor microenvironmental heterogeneity. A LASSO-derived prognostic model was established and validated in independent cohorts. Drug sensitivity prediction and supportive functional assays (EdU assays, qRT-PCR, immunohistochemistry) were performed for representative RMEs. RMEs were broadly upregulated across cancers and showed strong associations with CNV gains. Machine learning identified 12 RMEs that reliably discriminated tumor from normal tissues. Single-cell transcriptomic analysis showed that 10 of the 12 selected RMEs (DKC1, METTL1, NAT10, TRMT1, RPUSD1, PUS1, WDR4, TRMU, ADAT2, GTPBP3) exhibited higher expression in tumor-infiltrating cells compared with adjacent normal tissues. T-cell subpopulations displayed marked heterogeneity, with ADAT2 preferentially enriched in regulatory T cells. CellChat analysis revealed T cell subsets as key mediators of intercellular communication via multiple immune-related pathways. A 6-gene prognostic model exhibited independent prognostic power and was integrated into a well-calibrated nomogram. Drug-response prediction revealed that high-risk patients exhibited enhanced sensitivity to microtubule-targeting agents and kinase inhibitors, whereas low-risk patients showed preferential response to epigenetic modulators. Importantly, supportive functional assays showed that NAT10 knockdown, validated by qRT-PCR, was associated with reduced proliferative activity in HCC cells as evidenced by EdU assays, and IHC validation further corroborated its overexpression in clinical tumor specimens compared to adjacent normal tissues. This study delineates a CNV-associated landscape of RME dysregulation across cancers and establishes a 12-RME diagnostic signature and a 6-gene prognostic model with robust predictive performance. Single-cell analyses reveal tumor- and cell-type-specific expression patterns of RMEs, while supportive functional data suggest a potential biological relevance of NAT10 in HCC. Collectively, these findings provide an association-based framework for understanding the potential roles of RNA modification programs in cancer progression and clinical stratification.",

However, whether such mis-splicing yields stable, pathogenic proteins remains unclear. Here, we identify a TDP-43-repressed cryptic exon in Protein kinase N1 (PKN1), designated PKN1-5a1, which is activated in ALS patient brains and introduces a premature termination codon. This aberrant transcript escapes nonsense-mediated decay and is translated into a truncated peptide, PKN1-N207 (PKN207), detectable in AD brains with TDP-43 pathology. In mice, PKN207 impairs cognition, memory, and synaptic plasticity. Our findings demonstrate that TDP-43 loss-induced cryptic splicing can generate stable neurotoxic polypeptides, revealing a peptide-mediated mechanism in TDP-43 proteinopathies.",

The striatum and cortex are primarily affected by the gradual neuronal dysfunction and loss caused by the mutant huntingtin (mHTT) protein. Although there have been notable improvements in symptomatic management, curative treatments remain unavailable. A promising treatment option that offers specifically designed interventions to decrease or eradicate mutant HTT expression is gene therapy. RNA-targeted treatments (antisense oligonucleotides, RNA interference), DNA editing methods (Clustered Regularly Interspaced Short Palindromic Repeats/caspase 9, zinc finger nucleases, Transcription Activator-like Effector Nuclease), and advanced delivery systems (viral and non-viral vectors, lipid nanoparticles, exosomes) are just a few of the many approaches that are presently being researched. AMT-130 and tominersen clinical trials provide crucial information about the viability, security, and effectiveness of gene therapy for HD. It is hoped that developments in genome editing and delivery methods would make gene therapy a viable treatment for HD. However, challenges remain, including immunological responses, blood-brain barrier penetration, and off-target consequences. This review delves into the latest developments in HD gene therapy, highlighting new approaches, obstacles, and potential future paths to a permanent cure.",

We developed machine learning models to estimate the biological age of more than 40 distinct cell types-spanning neuronal, immune, glial, endocrine, epithelial, and musculoskeletal origins-using over 7,000 plasma proteins measured in 60,000 individuals across three cohorts, comprising the largest human plasma proteomics aging study to date. Individuals showed heterogeneous aging profiles, with 20-25% exhibiting accelerated aging in a single cell type and 1-3% across ten or more cell types. APOE genotype showed antagonistic aging effects in different cell types: APOE4 carriers exhibited older astrocytes but younger macrophages, while APOE2 carriers showed the inverse. Cellular aging signatures were uniquely associated with disease status and predicted incident disease and mortality over 15 years of follow-up. Amyotrophic lateral sclerosis (ALS) showed the strongest association with skeletal myocyte aging (hazard ratio = 12.7 for extreme accelerated versus youthful aging). In Alzheimer's disease (AD), prevalent cases showed accelerated aging across multiple neural and peripheral cell types, with extreme astrocyte aging conferring AD risk comparable to APOE4 carrier status. Moreover, extreme astrocyte aging increased AD risk in APOE4/4 carriers threefold, while youthful astrocytes strikingly reduced risk. Beyond neurodegeneration, respiratory cell aging identified smokers at 58% higher lung cancer risk, and myeloid aging identified normoglycemic individuals at higher diabetes risk. Both specific cellular vulnerabilities and cumulative aging burden influenced survival, wherein youthful immune or neuronal profiles were protective. A polycellular aging risk score provided robust mortality risk stratification across platforms and cohorts. These findings establish a framework for quantifying biological aging at the cellular resolution using plasma proteomics, revealing heterogeneity in aging trajectories and their impact on disease susceptibility and resilience.",
"41752118": "ID: 41752118\nTitle: Amyotrophic Lateral Sclerosis (ALS) Genetics and Microbiota: A Comprehensive Review.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a severe, progressive neurodegenerative disorder characterized by the loss of upper and lower motor neurons, affecting 0.5 to 2.6 per 100,000 people, with a median survival of 2 to 5 years. It is increasingly seen as a multisystem disorder, sharing essential clinicopathological features with Frontotemporal Dementia (FTD). This convergence arises from overlapping molecular processes, including severe oxidative stress, glutamate-mediated excitotoxicity, mitochondrial dysfunction, and widespread aggregated TDP-43 proteinopathy in both sporadic and familial cases. Several key genetic factors have been identified, particularly mutations in C9orf72, SOD1, TARDBP, and FUS, which serve as important targets for novel treatments, such as Tofersen, a recently approved SOD1-specific antisense oligonucleotide (ASO) gene therapy. Additionally, there is increasing evidence of the gut-brain connection. Dysbiosis, involving species such as Akkermansia muciniphila, and lower levels of neuroprotective metabolites, such as nicotinamide, may affect the course of the disease. As a result, treatment strategies are shifting toward a personalized approach. This includes using gene therapy, ranging from ASOs and RNA interference (RNAi) to new CRISPR-based genome editing. It also involves exploring microbiome-modulating treatments, such as specific probiotics and Fecal Microbiota Transplantation (FMT). While microbiome and gene therapies remain largely experimental, their potential is promising, as highlighted by the recent approval of Tofersen. These novel approaches could be further enhanced and guided by more robust diagnostic criteria and by investigating early multimodal treatment strategies to slow the progression of this complex disease.",
"41761059": "ID: 41761059\nTitle: A weight-sharing Bayesian neural network for consistent feature selection with applications in cancer gene expression data.\nAbstract: BACKGROUND : Advances in sequencing technologies generate extensive genetic information. Datasets such as the Cancer Genome Atlas (TCGA) BRCA facilitate large-scale cancer gene expression analyses, providing insights into the molecular mechanisms driving tumor progression. Effective feature selection\u2014identifying cancer or its subtype-related genes from expression profiles\u2014is critical, as it enhances diagnostic accuracy and guides personalized therapies. However, feature selection is hindered by dimensionality, low sample sizes, and nonlinear interactions within the data, making traditional models, including LASSO and its Bayesian counterparts, inadequate for interpretable feature selection. We thus propose a novel weight-sharing Bayesian neural network (wsBNN) leveraging shared spike-and-slab priors within a neural network framework to enable adaptive weight shrinkage for efficient and interpretable feature selection. RESULTS : We incorporate a scalable variational Bayes inference embedded in backpropagation while ensuring effective feature selection. Studying the theoretical properties of the variational posterior shows insights into the performance and theoretical guarantees of wsBNN. Both simulated and real-world dataset experiments show that wsBNN surpasses state-of-the-art nonlinear methods, including frequentist neural networks, in terms of predictive performance and consistency in feature selection. Furthermore, it competes well with classical methods such as Random Forests and Gradient Boosting. TCGA BRCA data study highlights wsBNN\u2019s practical applicability in identifying key biomarkers, particularly in Breast Cancer analysis. The model effectively captured cancer-associated genes and pathways\u2014particularly those related to ERBB2 and PI3K/AKT signaling, immune regulation, and cell cycle control\u2014showing superior biological relevance and interpretability compared to baseline methods. CONCLUSIONS : Our findings\u2014e.g., consistently identifying relevant biomarkers\u2014position wsBNN as a promising approach for feature selection in high-dimensional genomic datasets and show its potential to advance precision medicine. By integrating weight-grouping with shared spike-and-slab priors within a Bayesian neural network, wsBNN effectively balances sparsity, interpretability, and scalability. wsBNN\u2019s ability to recover biologically relevant genes and pathways highlights its importance for interpretable genomic analysis.",

Their ability to cross the blood-brain barrier, reflect the molecular state of parent cells, and deliver functional cargo positions them as uniquely suited tools for precision diagnostics and targeted therapeutics in neuropsychiatric disorders. This narrative review synthesizes current advances in exosome biology, isolation technologies, and multi-omics profiling to evaluate their utility as biomarkers for early detection, disease stratification, and treatment monitoring across major psychiatric conditions, including depression, bipolar disorder, schizophrenia, and neurodevelopmental disorders. We further examine innovative therapeutic strategies leveraging engineered exosomes for targeted delivery of small molecules, RNA therapeutics, and gene-editing systems to neural circuits implicated in psychiatric pathophysiology. Key challenges such as standardization of isolation methods, cargo heterogeneity, and translational scalability are critically discussed alongside emerging solutions from nanotechnology and machine learning-driven biomarker discovery.

"41766646": "ID: 41766646\nTitle: EpGAT: integrating epigenetics and 3D genome structure to predict alternative splicing and polyadenylation.\nAbstract: Understanding how the 3D structure of the genome influences gene regulation is a growing area of interest, particularly in the context of alternative post-transcriptional regulatory events such as alternative splicing (AS) and alternative polyadenylation (APA). These processes are essential for generating transcript and protein diversity, and they are tightly coordinated with transcription. However, despite their biological importance, the relationship between chromatin interactions and alternative pre-messenger RNA regulation remains poorly understood. This gap largely stems from a lack of computational tools capable of integrating structural genomic data with RNA processing dynamics. Exploring how chromatin interactions and epigenetic landscapes shape these events is essential for uncovering the multilayered regulation of gene expression. To bridge this gap, we present EpGAT, a graph attention network-based model that integrates epigenetic read coverage and chromatin interaction data to predict and quantify AS and APA events. By explicitly modeling the spatial organization of the genome, EpGAT captures the regulatory influence of chromatin looping and long-range genomic interactions on RNA processing. The model's predictions are validated through rigorous cross-cell line and cross-chromosome evaluations, affirming its generalizability and reliability. Beyond prediction, EpGAT offers interpretability by tracing learned parameters back to genomic features, enabling the identification of active enhancers, mapping promoter-enhancer connectivity, and pinpointing the epigenetic factors most critical to specific RNA processing events. These capabilities make EpGAT a powerful tool for dissecting the complex interplay between genome architecture and transcriptomic regulation. More broadly, it provides a generalizable framework for multiple tasks to study the link between 3D genome organization, epigenetic signals, and RNA processing.",

We aimed to pinpoint causal genes and evaluate their utility for MS risk prediction. We integrated MS genome-wide association study summaries with brain-derived splicing quantitative trait loci (sQTLs) and expression quantitative trait loci (eQTLs) via summary-data-based Mendelian randomization (SMR) and colocalization analyses to identify potential causal genes. Weighted gene coexpression network analysis (WGCNA) of the E-MTAB-5151 dataset identified MS-associated gene modules. LASSO regression determined the core gene signature. GO and KEGG enrichment analyses, immune infiltration, and gene set enrichment analysis (GSEA) explored the biological relevance. Using an independent protein quantitative trait loci (pQTL) dataset, key genes were further validated for pQTL-MS associations. SMR identified 28 sQTL genes and 66 eQTL genes for MS, 23 and 51 of which passed the colocalization tests, respectively. WGCNA identified three MS-associated modules, and their intersection with SMR genes prioritized 23 key genes. Functional enrichment analysis of the module genes and SMR genes highlighted the consistent involvement of immune-related pathways in MS, including lymphocyte activation and NF-\u03baB signalling. LASSO regression established a 10\u2013gene signature (ACP2, IL7, MYNN, RGS1, SAE1, SP140, TRAF3, TSPAN31, TYMP, and ZC2HC1A) with high predictive accuracy (AUC\u2009=\u20090.983 in internal validation; AUC\u2009>\u20090.70 across three external datasets). Immune infiltration analysis revealed a consistent immune cell expression pattern, in which the expression of MS risk genes was positively associated with naive CD4+ T cells and resting mast cells, but negatively associated with activated mast cells. In contrast, MS protective genes exhibited the opposite pattern. Furthermore, the integration of the MS genome-wide association study statistics validated ZC2HC1A and TRAF3 at the protein level. GSEA further linked both genes to the Hedgehog signalling pathway. Integrating genomic, transcriptomic, and proteomic data, we identified candidate causal genes for MS with robust evidence. ZC2HC1A and TRAF3 have emerged as promising biomarkers and mechanistic candidates for MS. Future follow-up functional studies are warranted to elucidate their molecular roles in MS pathogenesis.",

While traditionally studied for their roles in development, ZFPs have emerged as critical effectors and therapeutic targets across a wide spectrum of human pathologies, including cancer, neurological disorders, and autoimmune diseases. This review systematically dissects the molecular mechanisms by which dysregulated ZFP activity drives disease pathogenesis, using ischemic stroke as a central exemplar to illustrate their multifaceted roles. We detail how specific ZFPs orchestrate key stroke risk factors such as hypertension, hyperglycemia, and atherosclerosis, subsequently govern post-ischemic injury cascades, including neuroinflammation, programmed cell death, and blood-brain barrier disruption. Addressing the long-standing challenge of ZFPs as \"undruggable\" targets, we critically evaluate cutting-edge therapeutic strategies poised to modulate their function with precision. These include small-molecule modulators, targeted protein degraders (PROTACs), zinc finger nuclease (ZFN)-based gene editing, and advanced nanocarrier delivery systems, complemented by high-throughput computational screening. By integrating deep mechanistic insights with novel translational approaches, this review establishes a pioneering pan-disease framework for targeting ZFP networks. We provide a structured roadmap for future research and highlight the immense potential of ZFPs as a new class of master regulatory targets for developing novel and feasible therapies in ischemic stroke and beyond.",

Their complex pathogenic mechanisms remain incompletely understood, and effective disease-modifying therapies are still lacking. Traditional animal models and two-dimensional (2D) cell culture systems exhibit notable limitations in structural complexity, human relevance, and translational validity, making it difficult to faithfully recapitulate human-specific neuropathology. In recent years, brain organoid technology derived from induced pluripotent stem cells (iPSCs) has advanced rapidly, enabling the self-organization of diverse neuronal and glial cell types within a three-dimensional (3D) architecture that partially mimics human brain development and disease-related pathological events. When integrated with CRISPR-Cas9-based genome editing and multi-omics profiling, organoids support causal mechanism studies, target validation, and individualized drug-response prediction, highlighting their growing value in early-stage drug discovery. Despite current challenges-including insufficient maturation, lack of vascularization and immune components, and batch variability-the continuous progress in bioengineering, microfluidic systems, and artificial intelligence (AI)-driven multimodal data analysis is steadily expanding the translational potential of organoids as human-relevant preclinical models.

"41796799": "ID: 41796799\nTitle: RNA-binding proteins TDP-43 and FUS promote R-loop resolution and regulate transcription termination.\nAbstract: TDP-43 and FUS are RNA-binding proteins involved in the regulation of diverse RNA-processing events and have been strongly implicated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). We have previously demonstrated the role of symmetrical dimethylation (me2s) of a conserved arginine residue (R1810 in human POLR2A) in the C-terminal domain (CTD) of RNA polymerase II (RNAPII), which facilitates the recruitment of the Tudor domain-containing protein SMN to resolve R-loops at transcriptional termination sites. Here, we demonstrate that TDP-43 and FUS contribute to transcription termination through the R1810me2s-SMN pathway. Our data show that TDP-43-and to a lesser extent, FUS-are recruited to chromatin via this pathway, and that disruption of their recruitment leads to defective RNAPII termination. This impairment results in the accumulation of R-loops and elevated DNA damage to gene terminators. Using transcriptome-wide analyses, we further show that TDP-43 RNA-binding sites are highly correlated with regions of R-loop formation. Importantly, we find that the RNA-binding activity of TDP-43 is essential for its role in resolving R-loops and promoting efficient transcription termination. These findings establish a mechanistic link between TDP-43/FUS, R-loop resolution, and transcription termination, providing new insights into how their dysfunction may drive genome instability and contribute to the pathogenesis of ALS and FTD.",

"41804798": "ID: 41804798\nTitle: Cofilin hyperphosphorylation triggers TDP-43 pathology in sporadic amyotrophic lateral sclerosis.\nAbstract: Pathological forms of TAR-binding protein 43 (TDP-43), involving its aberrant mislocalization to the cytoplasm, inclusion formation, hyperphosphorylation and fragmentation, are present in \u223c45-50% frontotemporal dementia (FTD) and Alzheimer's disease individuals, and most (97%) amyotrophic lateral sclerosis (ALS) cases. Hence, identifying mechanisms that induce TDP-43 pathology are central to neurodegeneration and developing new therapeutic targets in these conditions. Cofilin is a multi-functional protein with a crucial role in regulating the actin cytoskeleton. Actin has important neuronal-specific activities in dendritic spines, axonal growth cones and synapses and it is in constant equilibrium between two forms: monomeric globular actin (G-actin) and polymeric filamentous actin (F-actin). Cofilin controls actin dynamics by depolymerising and severing actin filaments. When cofilin is phosphorylated (at Serine-3) by LIM kinase1 (LIMK1), it becomes inactive, leading to production of more F-actin. Defects in cofilin are well described in other neurodegenerative disorders, unlike in ALS. We examined phosphorylation of cofilin and actin dynamics in post-mortem spinal cord tissue from sporadic ALS (SALS) patients, the TDP-43 rNLS8 transgenic mouse model, and NSC34 motor neuronal cells expressing cytoplasmic TDP-43. F-actin was pharmacologically stabilized to mimic cofilin hyperphosphorylation, and TDP-43 pathology was assessed. Neuronal cells were treated with a non-phosphorylatable cofilin S3A peptide (MAAGVAVSDGVIKVFN), and TDP-43 pathology and apoptosis were evaluated. Here, we show that cofilin is hyper-phosphorylated in human ALS and disease models compared to controls. This was detected in spinal motor neurons from sporadic ALS (SALS) patients and a TDP-43 mouse model (rNLS8) displaying key ALS phenotypes, and in motor neuronal NSC34-cells expressing cytoplasmic TDP-43. Supporting this observation, more F-actin relative to G-actin was present in cortical/spinal cord lysates from SALS patients and TDP-43 rNLS8 mice, and NSC34-cells expressing TDP-43. We also show that mimicking cofilin hyperphosphorylation by pharmacological stabilization of F-actin induced TDP-43 pathology: cytoplasmic mislocalization, inclusion formation, hyperphosphorylation, and fragmentation, and promoted its recruitment into stress granules (SGs). Furthermore, we detected increased levels of LIMK1 phosphorylation and tropomyosin isoforms 4.1 and 4.2 in SALS patients. These findings reveal aberrant cofilin hyperphosphorylation disrupts actin dynamics, triggering TDP-43 pathology and SG recruitment in SALS. They imply that preventing cofilin phosphorylation is a novel therapeutic strategy applicable to most ALS cases. Treatment of neuronal cells with the S3A peptide prevented features of TDP-43 pathology and apoptosis compared to control peptides. These findings thus describe a novel pathogenic mechanism producing TDP-43 pathology, applicable to most ALS cases and other neurodegenerative diseases.",

However, the upstream modulators of this process remain poorly defined. Here we identify cyclic GMP-AMP synthase (cGAS) as a central mediator of TDP-43 pathology and associated mis-splicing. cGAS expression was elevated in ALS patient brains and enriched across activated microglia. In human iPSC-derived microglia-motor neuron co-cultures, neuronal TDP-43 pathology triggered microglial cGAS activation, whereas pharmacological inhibition with a potent human cGAS inhibitor reduced phosphorylated TDP-43, restored lysosomal and phagocytic programs, normalized microglial reactivity, and reversed TDP-43-associated RNA splicing defects. In vivo, cGAS inhibition in TDP-43 Q331K mice reversed widespread RNA splicing abnormalities across neurons and oligodendrocyte lineage cells, attenuated neurodegenerative pathology, and preserved motor function. Together, these findings identify cGAS as a druggable upstream regulator linking innate immune signaling to TDP-43-dependent RNA mis-splicing and neurodegeneration, and establish cGAS inhibition as a promising therapeutic strategy for ALS.",

Aside from the identification of causal genes, other difficult challenges to informing GWAS include characterizing the roles of predicted causal genes in disease and providing additional functional context, such as the cell-type predictions or biological pathways in which causal genes operate. Leveraging single-cell transcriptomics (scRNA-seq) can assist in informing BMD GWAS by linking disease-associated variants to genes and providing a cell-type context for which these causal genes drive disease. Here, we use large-scale scRNA-seq data from bone marrow-derived stromal cells cultured under osteogenic conditions (BMSC-OBs) from Diversity Outbred (DO) mice to generate cell type-specific networks and contextualize BMD GWAS-implicated genes. Using trajectories inferred from the scRNA-seq data that map cell state transitions, we identify networks enriched with genes that exhibit the most dynamic changes in expression across trajectories. We discover 21 network driver genes, which are likely to be causal for human BMD GWAS associations that colocalize with expression/splicing quantitative trait loci (eQTLs/sQTLs). These driver genes, including Fgfrl1 and Tpx2, along with their associated networks, are predicted to be novel regulators of BMD via their roles in the differentiation of mesenchymal lineage cells. In this work, we showcase the use of single-cell transcriptomics from mouse bone-relevant cells to inform human BMD GWAS and prioritize genetic targets with potential causal roles in the development of osteoporosis.",

The apolipoprotein E4 (APOE4) allele is the strongest genetic risk factor for late onset AD, with each copy increasing risk approximately two- to three-fold, and homozygous carriers facing up to a 10- to 15-fold higher risk compared to APOE3 carriers. APOE4 contributes to diverse pathogenic mechanisms including lipid dysregulation, neuroinflammation, synaptic dysfunction, and vascular compromise. The precise, allele-specific correction of APOE4 therefore holds transformative therapeutic potential. CRISPR-based genome editing technologies, including nuclease disruption, base editing, and prime editing, offer unprecedented opportunities to directly modify APOE4 at its genomic source. Here, we review mechanistic underpinnings of APOE4 pathology, summarize current gene editing platforms for APOE4 correction, evaluate relevant in vitro and in vivo model systems, and assess delivery strategies with an emphasis on nanoparticle and exosome based approaches. We highlight recent breakthroughs in exosome mediated APOE4 editing while addressing ongoing technical hurdles in allele specificity and translational barriers such as Cas nuclease immunogenicity, limited delivery efficiency across the blood brain barrier (BBB), and concerns over long term genomic safety. This review concludes that overcoming BBB constraints remains the most significant challenge for clinical translation, and that innovations in exosome and nanoparticle based delivery platforms represent the most promising strategies for advancing CRISPR therapeutics for AD.",

Cytoplasmic dsRNA (cdsRNA) triggers a type-I interferon response in human neural cells, leading to their death, and is found in neurons of C9ORF72-ALS patients. Here, we report the spatial coincidence of cdsRNA and pTDP-43 inclusions in human postmortem tissue with Alzheimer's disease pathology, and upregulated interferon response genes in affected regions. CdsRNA also accumulates in a human TDP-43 G298S iPSC cortical neuronal model. We use cryptic exon detection as a proxy for TDP-43 mislocalization and demonstrate that FDA-approved JAK inhibitors baricitinib and ruxolitinib, which block interferon signaling, show protective effects only in brains with elevated cryptic exon expression. A CRISPR screen reveals TYK2 as a top hit, and TYK2 knockdown and the selective TYK2 inhibitor deucravacitinib rescue cdsRNA-induced toxicity.

Already, much is known about therapeutic targets and how they would need to be manipulated to mitigate disease. For such gene therapies to move to the clinic, potent CNS delivery vehicles are needed. One line of investigation focuses on adeno-associated viruses (AAV) to address this need. In particular, blood-brain barrier (BBB)-penetrant AAV capsids are of interest due to the relative ease of their intravenous administration. This review will introduce this topic and provide an update on recent developments. First, we describe the physical barriers that must be overcome for AAV-delivered gene therapies to reach target cells in the CNS. We then put a spotlight on the natural AAV9 capsid's inherent propensity to cross the BBB and key lessons learned from its use for delivering a therapeutic payload for the treatment of spinal muscular atrophy. Next, we summarize methods for engineering recombinant AAV (rAAV) capsids with improved brain penetrance, and present in vitro paradigms for predicting their capacity to cross the human BBB. We also present strategies for side-stepping the delivery limitations of existing rAAV vectors.

Alternative splicing of TARDBP, the gene encoding TDP43, leads to a surprising diversity of RNA and protein isoforms with unique functions and potential implications for disease pathogenesis. Here, we review the production, properties, and functional consequences of alternative splicing in the development of ALS and FTD, focusing primarily on TDP43 due to its integral connection with the pathogenesis of sporadic as well as familial forms of these diseases. We synthesize current evidence on the biology of alternative TARDBP splicing, highlight key questions regarding its role in TDP43 proteinopathies such as ALS and FTD, and touch on the larger phenomenon of alternative splicing and its relationship to disease.",

While metabolic dysfunction is increasingly recognized in ALS, the mechanistic link between impaired energy metabolism and TDP-43 pathology remains unknown. Here, we show that cytoplasmic TDP-43 directly disrupts glycolysis by targeting hexokinase 1 (HK1), the first rate-limiting enzyme of the pathway. In cells expressing a TDP-43 variant lacking its nuclear localization signal and in patient-derived iPSC motor neurons, TDP-43 accumulation in the cytoplasm reduces glycolytic capacity, indicating a neuron-intrinsic metabolic defect. Across cellular models including patient-derived neurons, TDP-43 mutant mice, and postmortem spinal cord tissue from ALS patients, we observe consistent decreases in HK1 protein level, mitochondrial association, and enzymatic activity, despite unchanged transcript levels. Mechanistically, cytoplasmic TDP-43 directly binds to HK1, disassociating it from mitochondria and promoting its sequestration into insoluble aggregates. This mislocalization impairs glycolysis and increases neuronal vulnerability. Notably, compensation for HK1 loss reduces cytoplasmic TDP-43 and ubiquitin accumulation, improves motor performance, and prolongs survival in TDP-43-associated ALS models. Together, these findings identify a previously unrecognized mechanism by which TDP-43 impairs glycolysis through HK1 misregulation and highlight glycolytic restoration as a potential therapeutic strategy in ALS.",
"41845971": "ID: 41845971\nTitle: The role of TDP-43 fragments in regular cellular functions and homeostatic failure.\nAbstract: Amyotrophic lateral sclerosis (ALS) is characterized by the progressive degeneration of motor neurons, leading to severe muscle weakness, loss of voluntary movement, and respiratory failure. A widely noted feature of the disease is the presence of TDP-43 proteinopathies. Under homeostatic conditions, the RNA/DNA-binding protein TDP-43 mainly resides in the nucleus, where it functions to regulate gene expression, controlling not only RNA transcription and splicing, but also stability and transport to the cytoplasm. Upon the arrival at ribosomes, TDP-43 may further moderate translation, acting as a global repressor of protein synthesis. However, in over 95% of ALS cases, TDP-43 mislocalises from the nucleus to the cytoplasm, where it enriches in cytoplasmic inclusions that are marked by the presence of misfolded, ubiquitinated, phosphorylated and fragmented protein species of TDP-43. Although recent studies have tried to untangle the relationship between TDP fragments on the one hand, and cytotoxicity as well as neurodegeneration on the other, the results are still a matter of debate. Here, we review our current understanding of the different TDP fragments derived from proteolytic cleavage as well as alternative splicing, addressing the different N-terminal and C-terminal species and evaluating differences in rodent and primate models. We focus our analysis on potential homeostatic functions of TDP fragments in the context of viral infections and myelination control, which could be pivotally interconnected. The findings illustrate several facets of fragmented TDP-43 protein species in scenarios of enhanced cellular stress. Gaining a detailed understanding could help to reveal new treatment options for ALS and other TDP-43 proteinopathies.",
"41855219": "ID: 41855219\nTitle: Epistasis mediates the role of negative frequency-dependent selection in bacterial strain structure.\nAbstract: Strain structure is a well-documented phenomenon in many pathogenic and commensal bacterial species, where distinct strains persist over time exhibiting stable associations between genetic or phenotypic traits. This structure is surprising, particularly in highly recombinogenic species like Streptococcus pneumoniae, because recombination typically breaks down linkage disequilibrium, the non-random association of alleles at different loci. Recent work suggests that multi-locus negative frequency-dependent selection (NFDS) acts to maintain allelic diversity across bacterial genomes, a pre-requisite for the existence of patterns of linkage disequilibrium. Here, using modeling and genomic analysis, we show that multi-locus NFDS can also shape bacterial strain structure through epistatic effects between these loci. We develop models of two NFDS mechanisms - metabolic niche differentiation and competition-colonisation trade-offs - and show how they can produce epistasis. Notably, both models generate frequency-dependent epistasis. Unlike classical constant sign epistasis, this acts to either reinforce or weaken existing linkage disequilibrium, making observed allele associations contingent on the evolutionary history of the population. We then use a dataset of over 3000 S. pneumoniae genomes to test our model predictions, and make observations consistent with frequency-dependent epistatic effects on gene associations. Our results extend and generalise previous theoretical work on the role of antigen-specific acquired immunity (a diversity-maintaining mechanism) on allele associations. Overall, this work contributes to a better understanding of the evolutionary processes shaping the structure of bacterial populations, which is central to predictive modeling of multi-strain pathogens.",

However, its application in Drosophila melanogaster has been constrained by inconsistent efficiency and limited repression amplitude. Here, we present embedded CRISPR interference (emCRISPRi), an advanced gene-silencing platform that integrates transcriptional repression domains (Mxi and TRD) into a structurally flexible region of dCas9. This design significantly enhances silencing efficiency, enabling robust repression of coding genes and cis-regulatory elements, particularly at transcription start site (TSS)-proximal regions. emCRISPRi demonstrates improved gene-silencing activity compared to RNA interference (RNAi) at several tested loci and facilitates strong phenotypic rescue via unmodified cDNA. Its versatility is demonstrated through the dissection of Hippo pathway interactions and the mitigation of TDP-43-induced neurotoxicity in an amyotrophic lateral sclerosis (ALS) model.

"41863273": "ID: 41863273\nTitle: PROTAC-Based Therapeutics: From Design to Clinical Potential in Neurodegenerative Disease.\nAbstract: Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and ALS, are characterized by a progressive loss of neuronal function and a direct correlation between their progression and proteins with misfolded and aggregated structures. Although significant efforts have been made, and various therapies are available for their treatment, they show only a modest beneficial response to their progression. The main reasons for this phenomenon can be correlated with a loss of target specificity, low permeability in crossing the BBB, and their ineffectiveness in clearing proteins from neurons. Within this therapeutic paradigm, proteolysis-targeting chimaeras, or PROTACS, have been identified as a novel therapeutic strategy. Unlike traditional smallmolecule inhibitors, PROTACS take advantage of the natural ubiquitin proteasome system to specifically degrade target proteins. At a molecular level, PROTACS consist of a ligand that specifically recognizes a target protein, a linker, and an E3 ligand-recruiting ligand that specifically recruits an E3 ligase. At a therapeutic level, this offers the advantage of catalytic protein degradation that should allow for reduced dosing. Preclinical studies carried out using neurodegenerative disease models have shown the potential for selective targeting of major pathologic proteins, such as tau, \u03b1- synuclein, TDP-43, and mHTT, which are crucial for pathogenesis. In addition, developments in the formulation of brain-permeable PROTACS, understanding of E3 ligase expression levels in the central nervous system, and application of iPSC-derived neuronal systems have contributed to rapid developments in this area. Although pharmacokinetic modification and degradation-specific approaches are still required, evidence suggests a major therapeutic potential for PROTAC-based approaches for the treatment of neurodegenerative disorders.",

Until recently, only symptomatic management was available. This review provides pediatric neurologists with a comprehensive, practice-oriented overview of emerging disease-modifying therapies for AS, focusing on therapeutic approaches advancing through clinical development. The molecular pathophysiology of AS, natural history considerations critical for trial interpretation, and the current evidence for antisense oligonucleotide (ASO) therapies (ION582, GTX-102/apazunersen, rugonersen), gene replacement approaches (MVX-220), and next-generation strategies including CRISPR-based gene editing, artificial transcription factors, small molecules, and novel delivery platforms are reviewed. ASO therapies targeting the UBE3A antisense transcript represent the most clinically advanced approach, with three candidates showing proof-of-concept efficacy in Phase 1/2 studies and two advancing to pivotal Phase 3 trials. Gene replacement therapy offers potential single-administration treatment but faces challenges regarding safety, immune responses, and durability. Next-generation approaches including CRISPR activation, epigenetic editing, and blood-brain barrier-penetrating delivery systems show preclinical promise.

As treatment for CNS disorders is primarily palliative, the underlying causes of disease progression are not addressed through conventional pharmacologic therapies. Gene therapy has the potential to address these root causes of disease progression; however, many of the vectors used in gene therapy (e.g., adeno-associated viruses (AAVs)) have limitations such as immunogenicity, low cargo capacity, and crossing the blood-brain barrier (BBB). These limitations have led to significant progress in the development of non-viral gene delivery systems. Compared with viral vectors, non-viral platforms offer improved safety profiles, greater design flexibility, lower production costs, and superior suitability for repeated administration. This review reports recent advancements in the development of non-viral platforms for CNS gene delivery and focuses on lipid-based nanoparticles, polymeric nanoparticles, exosome-based techniques, and new hybrid technologies. Particular emphasis is placed on nanoparticle modification approaches to enhance BBB penetration and enable delivery of genome-editing technologies (CRISPR/Cas systems). The review provides explanations of clinical trials, regulatory considerations, and manufacturing issues that result from the recent developments noted above. It also explores the emerging role of artificial intelligence in supporting carrier design and enhancing delivery efficiency.

While the association between chromatin accessibility and gene expression levels is critical for transcriptional regulation, it remains incompletely characterized. Saccharomyces cerevisiae is a key eukaryotic model organism and a widely used chassis in synthetic biology, but studies on predicting gene expression from chromatin accessible regions are lacking. We developed Yeast-Gene, a supervised machine learning model that uses k-mer features from chromatin accessible regions to predict gene expression. Yeast-Gene focuses on local sequences of a few hundred base pairs within chromatin accessible regions. The model achieves an Area Under the Curve (AUC) of 0.90. The interpretability analysis identified AAGAA and CAAGA as highly influential motifs in the prediction of gene expression, and both motifs are potentially associated with mRNA splicing.

Recently, it was shown that Annexin-A11 and TDP-43 coaggregate specifically in TDP-C. Current literature on the genetic associations with TDP-C, reviewed here, lacks a discernible corpus of robust or replicated findings. In this study, using blood tissue, we completed whole genome sequencing to investigate ANXA11 and TARDBP genetic variants for their association with TDP-C. Then, we completed genome-wide hypothesis-free analyses using artificial intelligence to identify rare pathogenic variants associated with TDP-C. (1) We tested common variants in ANXA11 and TARDBP for their association with 37 TDP-C cases vs 290 controls. We attempted to replicate our findings in a different cohort of 467 TDP-C cases vs 3,153 controls and contrasted them with cohorts of TDP-A and TDP-B. (2) AI-guided analyses were completed to prioritize pathogenic rare variants associated with TDP-C in our cohort. (1) Four common variants in ANXA11 (rs113772135, rs2789686, rs1079242, rs61860017) were significantly associated with TDP-C in the discovery cohort and replicated in the other cohort of TDP-C but not in TDP-A or TDP-B, providing evidence for ANXA11 specific association with TDP-C. Rs1079242-A showed the most robust replication (p = 7.35 \u00d7 10-05) and correlates with higher ANXA11 level in CSF (p = 4 \u00d7 10-11). No associations were found between TARDBP and TDP-C (p > 0.05). Using AI-guided rare variant analyses, we identified a pathogenic variant in FIG4, a gene that has been implicated in amyotrophic lateral sclerosis (ALS). Because of the observed potential genetic overlap between some ALS genes and TDP-C, we leveraged mendelian randomization and found that ALS genetic load is associated with TDP-C risk (p = 0.0046). This study provides replicated evidence for the association between common variants in ANXA11 with TDP-C. Knowing rs1079242-A affects ANXA11 level in CSF, future studies may aim to investigate ANXA11 level as potential CSF biomarker for TDP-C. Moreover, FIG4 and ANXA11 have been implicated in the inositol pathway. Our results provide novel insights into the genetic risk of TDP-C and offer new clues about its underpinning mechanisms.",

Despite marked genetic and pathological heterogeneity, a unifying pathogenic framework remains lacking. We propose that axonal transport impairment represents an early and convergent but genotype-modulated upstream vulnerability in ALS, contributing to distal synaptic failure, bioenergetic stress, protein aggregation, neuroinflammation, and neuronal death. Across many ALS models, including SOD1, TARDBP (TDP-43), FUS, and C9orf72, transport deficits are frequently detectable in presymptomatic stages, often preceding overt motor neuron loss or clinical manifestation, although temporal ordering varies by molecular subtype. Human data from induced pluripotent stem cell-derived motor neurons and neuroimaging in mutation carriers further support early transport dysfunction in both familial and sporadic ALS. We synthesize genetic, cellular, and systems-level evidence demonstrating that diverse ALS-associated mutations converge on intracellular trafficking machinery through distinct but interacting mechanisms, disrupting long-range cargo delivery and clearance in motor neurons. This framework provides a mechanistic basis for selective motor neuron vulnerability, the dying-back pattern of neuromuscular junction degeneration, and the emergence of downstream pathological hallmarks including mitochondrial dysfunction, excitotoxicity, aggregation, and inflammation. This model generates testable predictions regarding presymptomatic transport biomarkers and the timing of therapeutic intervention. We discuss implications for biomarker development and therapeutic strategy, proposing restoration of axonal transport as a central component of rational multimodal disease modification in ALS.",

Agentic artificial intelligence (agentic AI) can accelerate discovery by automating components of the scientific workflow, including information retrieval, data analysis, and knowledge synthesis. OpenScientist, an open-source agentic AI co-scientist, aims to accelerate biomedical discovery by semi-autonomously investigating scientist-defined queries and generating clinically relevant, verifiable scientific insights. Domain experts evaluated OpenScientist for novel discoveries in four clinical case studies: (1) a prespecified analysis in a community-based Alzheimer's disease biomarker cohort, (2) unsupervised modeling for plasma proteomic survival prediction, (3) hypothesis investigation in single-cell transcriptomic data from neurons with neurofibrillary tangles, and (4) hypothesis generation with validation in a multiple myeloma dataset with a randomized negative control. OpenScientist completed analyses in minutes that otherwise would take weeks to months of human time and expertise. It identified %ptau217 as the best predictor of amyloid PET status, generated a plasma proteomic survival model with performance comparable to published models, proposed a mechanism linking tau pathology to altered lysosomal acidification, and generated multiple myeloma hypotheses that were validated in an external cohort while distinguishing true signal from randomized controls.

A growing body of evidence implicates cytoskeletal disruption as a central pathological mechanism in these conditions. Cytoskeletal proteins, including microtubules, actin filaments, tau, neurofilaments, and alpha-synuclein, not only provide structural integrity but also regulate axonal transport, synaptic connectivity, and neuroplasticity. Its dysfunction will lead to impaired intracellular trafficking, protein aggregation, and neuronal degeneration. This chapter explores clearly about the specific cytoskeletal abnormalities that are evident in major neurodegenerative disorders, highlighting the biological mechanisms such as tauopathy-induced microtubule instability in Alzheimer's, actin cytoskeleton dysregulation in Parkinson's, and neurofilament aggregation in ALS. Current therapeutic strategies aimed at the stabilizing cytoskeletal components, enhancing protein clearance, and restoring transport dynamics are examined, alongside the cutting-edge approaches including the gene therapy, CRISPR/Cas9 editing, and nanotechnology-based delivery systems. Challenges such as limited blood-brain barrier penetration, off-target toxicity, and patient heterogeneity are also discussed with the focus on need for precision medicine. Additionally, we have also explored the future directions that specifically focused on the biomarker development, combination therapies, and strategies to promote neuroregeneration and structural plasticity.

This mutation is a potential target for CRISPR/Cas9-based genome editing. However, the blood-brain barrier and limitations of current viral or nanoparticle-based delivery systems to neurons significantly restrict the clinical application of CRISPR-Cas9 in the brain. To address these challenges, we developed a drug delivery system using acerola-derived exosome-like nanoparticles (AELNs), which may overcome several limitations associated with human exosomes. AELNs stably form complexes with ribonucleoproteins (RNPs) comprised of Cas9 proteins and guide RNAs (gRNAs).

Drug delivery to BT presents a plethora of obstacles, such as poor bioavailability, drug targeting and its efficacy due to the complexity of the brain's structure, anatomy, and implications of the blood-brain barrier's (BBB) functionality. The anatomical complexity of the brain limits other conventional modes, viz., radiation and major surgery. Moreover, the conventional chemotherapeutics, including radiation therapy for BTs, develop drug resistance and can cause complications further. This review presents how nanotechnology-based drug delivery systems address these limitations when the drug is administered in a conventional mode. Liposomes, specialized nanoparticles (NPs) (nanoparticulate systems fabricated from polymers and gold), and dendrimers, other nanotechnology-driven carriers, were targeted for BT delivery. Nonetheless, their safety aspects, such as systemic toxicity, off-target effects of therapeutic agents, effective BBB permeability, and drug targeting, are elaborated. Mesoporous silica nanoparticles (MSNs) offer specialized delivery with the potential of drug targeting directly to BTs via their mesoporous structure, extensive surface area, and adjustable pore size, drug-loading and stimuli-triggered responsiveness. Targeting ligands via surface functionalization enhances the tumor-targeting attributes of MSN modalities while reducing systemic toxicity and off-target effects. To ensure calibrated dosing of anticancer drugs triggered through biophysical response, MSNs can respond to such biophysical or biochemical stimuli originating from the tumor microenvironment (TME). Novel modalities of MSN, previously considered as ineffective owing to BBB restrictions, offer gene-editing tools, small-interfering RNA (siRNA) and further advancement. Clinical oncology, molecular biology, and nanotechnology concordantly develop novel treatment avenues that could significantly modulates desired potential for BT patients. MSNs are regarded as effective nanocarriers targeting a drug to TME, as elaborated in this review, providing impetus to drug delivery, surface modifiability, and stimuli-triggered mechanisms, including both endogenous and exogenous stimuli.

However, the causal relationship between impaired autophagy and ALS remains ambiguous, necessitating further elucidation. This Mendelian randomization (MR) study employs a two-sample design, utilizing genetic instruments to proxy autophagy dysregulation as the exposure and ALS as the outcome. It incorporates summary statistics of ALS (27,205 cases, 110,881 controls), along with data on DNA methylation, RNA splicing, gene expression, and protein abundance quantitative trait loci (QTLs) in both blood and brain tissues (mQTL, sQTL, eQTL, and pQTL, respectively) sourced from European cohorts. Cis-variants situated proximal to or within the 604 autophagy-related genes, exhibiting robust associations with molecular alterations in autophagy, are employed as instrumental variables. Their causal links with ALS are assessed via summary-data-based MR (SMR) analyses, followed by Bayesian colocalization, sensitivity analyses, brain cell-specific MR analyses, protein-protein interaction (PPI), and druggable analyses. Consistent evidence supported the causal effects of two lysosome genes (FNBP1 and IDUA), one autophagy core gene (C9orf72), and one mitophagy gene (USP35) on ALS risk. Specifically, brain FNBP1 splicing level (OR = 1.18, p = 3.38E-5) and blood USP35 expression level (OR = 1.17, p = 5.94E-5) were positively associated with higher ALS risk.

This review consolidates recent experimental, transcriptomic, bioinformatic, and emerging clinical findings regarding the role of lncRNAs in NDDs. We examine how lncRNAs modulate common disease mechanisms, including protein misfolding and aggregation, neuroinflammation, mitochondrial dysfunction, ferroptosis, synaptic failure, and aging-related neurodegenerative processes.

Through CRISPR interference (CRISPRi) screening in human neurons, we identified the decapping scavenger enzyme (DCPS) as a novel genetic modifier of TDP-43 loss-of-function (LOF)-mediated neurotoxicity. Our findings reveal that TDP-43 LOF leads to aberrant mRNA degradation via dysregulating the properties and activity of processing bodies (P-bodies). TDP-43 interacts with P-body component proteins, potentially influencing their dynamic equilibrium and assembly into ribonucleoprotein (RNP) granules. Loss of TDP-43 hyperactivates P-bodies, increasing mRNA association and RNA decay. Reducing DCPS restores P-body integrity and RNA turnover, ultimately improving neuronal survival.

Benzimidazole, a privileged heterocyclic scaffold, has emerged as a promising pharmacophore in modulating key pathological targets across these disorders. In AD, benzimidazole derivatives inhibit cholinesterases, glycogen synthase kinase-3\u03b2 (GSK-3\u03b2), and glutaminyl cyclase (QC), thereby addressing cholinergic dysfunction, tau phosphorylation, and amyloid aggregation. In PD and HD, they act as monoamine oxidase-B (MAO-B) inhibitors, dopamine D1/D2 receptor modulators, and N-methyl D-aspartate receptor antagonists, improving dopaminergic signalling and reducing excitotoxicity. In ALS, benzimidazoles regulate acetylcholine dysfunction and inhibit receptor-interacting protein kinase 1 (RIPK1), limiting neuroinflammation and cell death. Preclinical studies demonstrate potent enzyme inhibition, often with IC50 values in the nanomolar to micromolar range, alongside favourable ADMET properties enabling blood-brain barrier penetration. Clinically, the glutaminyl cyclase inhibitor Varoglutamstat has advanced to Phase II trials for AD, while Riluzole remains the only food and drug administration (FDA)-approved benzimidazole drug for ALS.

METHODS: We performed integrative analyses of differentially expressed genes across GEO datasets (GSE43292 and GSE9820) and immune-related gene sets from ImmPort. Feature selection was refined using LASSO regression and SVM-RFE. Functional enrichment was assessed via GSEA and GSVA, while immune associations were evaluated with CIBERSORT and ESTIMATE. Key findings were validated in an independent dataset (GSE9820). RESULTS: Thirteen hub genes associated with SF3B3 were identified. SF3B3 expression correlated with enhanced antiviral defense, cytokine production, and immune signaling pathways. Higher SF3B3 levels were positively associated with adaptive immune populations\u2014including memory and na\u00efve B cells, CD4\u207a and CD8\u207a T cells, follicular helper T cells, and regulatory T cells\u2014while inversely correlated with activated memory CD4\u207a T cells, monocytes, macrophages, eosinophils, and activated dendritic cells. CONCLUSIONS: SF3B3 is closely linked to immune infiltration patterns in AS, highlighting its potential as a biomarker and a candidate target for therapeutic intervention. These findings provide a framework for future mechanistic studies and clinical applications.",

We review evidence that rG4s exist in two functionally distinct worlds. In the nucleus, rG4s fold co-transcriptionally to regulate gene expression and RNA processing and organizing membraneless organelles through liquid-liquid phase separation. Splicing regulation by rG4s is restricted to vertebrates and co-evolved with transcriptome complexity. In the cytoplasm, rG4s are actively maintained in an unfolded state by dedicated helicases and RNA-binding proteins, but fold upon stress to nucleate stress granules, that sequester mRNAs and sustain cell survival. When compartmentalization of rG4-protein interactions fails, cells lose both nuclear RNA processing control and cytoplasmic translational regulation and proper stress response. The same biophysical properties that make rG4s effective scaffolds for reversible phase separation in RNA processing, proteostasis, and acute stress become liabilities under chronic conditions: in ageing neurons, failure of rG4-protein homoeostasis transforms protective condensates into irreversible aggregates associated with \u03b1-synuclein, tau, TDP-43, and FUS pathology. We discuss the implications of a dynamic equilibrium of folded and unfolded rG4s in health and disease, with particular focus on their emerging roles in neurodegeneration.",

Considerable advancements in deep learning, transformer-based sequence models, graph neural networks, and multimodal architectures have greatly improved microbial classification accuracy, antibiotic resistance gene (ARG) detection, and resistance prediction. Taking metagenomic sequencing into consideration, these advancements have contributed to the development of sensitive, scalable, and non-invasive methods to profile microbiomes, determine novel resistance, and monitor AMR trends at the population level. This review summarizes recent advances in AI-aided microbiology, with a particular emphasis on AMR surveillance. Specific topics include deep learning frameworks for ARG annotation, emerging approaches to identifying new resistance genes, and multimodal applications (genomic and clinical metadata) aimed at improving phenotype prediction. The role of metagenome-assembled genomes (MAGs) to enhance AMR surveillance efforts is noted, along with their noted limitations relative to isolate genomes. The discussion includes the examination of explainable AI (XAI) techniques including SHAP, attention mechanism approaches, and gradient-based attribution approaches, with the aim of increasing transparency and clinical explainability. We also cover potential applications including AI-enabled non-invasive fecal microbiome diagnostics, laboratory automation, and environmental surveillance. While there has been significant progress, unresolved issues exist relating to dataset variations, liability of models to datasets, interpretability, and regulatory approval. Overcoming these barriers, however, will require standardized frameworks for these workflows, privacy-preserving federated learning methods, and interpretable AI frameworks for clinical and public health tools. AI could fundamentally change AMR surveillance by allowing for earlier resistance detection, advanced risk assessment recommendation, and improved monitoring strategies globally.",

While KRAS mutations are nearly universal, the broader RTK-RAS and MAPK signaling architecture and its relationship to treatment response remain incompletely defined. We conducted an integrative clinical-genomic analysis of 184 PDAC tumors stratified by age at diagnosis and gemcitabine exposure, interrogating somatic alterations across curated RTK-RAS/MAPK gene sets. Conversational artificial intelligence agents (AI-HOPE-RTK-RAS and AI-HOPE-MAPK) enabled dynamic cohort construction and pathway-level analyses, with findings validated using standard statistical methods. In late-onset PDAC, ERBB2 and RET mutations were significantly enriched in gemcitabine-treated tumors. Early-onset cases demonstrated differential enrichment of CACNA2D family alterations in non-treated tumors and higher frequencies of FLNB and TP53 mutations in treated disease. Importantly, late-onset patients not treated with gemcitabine who lacked RTK-RAS or MAPK alterations exhibited significantly improved overall survival. These findings reveal age- and treatment-dependent pathway dependencies beyond canonical KRAS status and support a precision oncology framework in PDAC. Conversational AI facilitated rapid, multidimensional clinical-genomic integration to uncover clinically relevant signaling substructures.",

This review explores the emerging potential of targeting non-coding RNAs (ncRNAs), such as microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and exosomal RNAs, to modulate pathogenic molecular pathways and address the underlying molecular origins of neurodegeneration. We evaluate the integration of advanced computational techniques for RNA structure prediction and gene regulatory network analysis, alongside chemical engineering strategies-such as Locked Nucleic Acids (LNAs) and phosphorothioate modifications-aimed at enhancing the stability and specificity of RNA-based molecules. Furthermore, we analyze cutting-edge delivery and editing technologies, including nanotechnology-driven solutions for precise neuronal targeting and the CRISPR/Cas13 system for direct ncRNA manipulation.The findings indicate that while challenges in delivery efficiency and long-term efficacy persist, the synergy of chemical engineering and computational modeling significantly improves the therapeutic profile of ncRNAs, with exosomal pathways offering a novel route for intercellular signaling modulation and biomarker discovery. Therapeutic interventions directed at specific clinical targets, such as miR-34a and BACE1-AS, demonstrate the capacity to influence protein aggregation and neuroinflammatory cascades. Although ncRNA-based therapies are currently in nascent stages, ongoing technological advancements in RNA editing and nanotechnology offer a transformative framework that could redefine the future of ND treatment and successfully halt disease progression rather than merely managing symptoms.",

Modulation of trans-acting spliceosome proteins changes specific patterns of splicing and contributes to the development of diseases. During Amyotrophic Lateral Sclerosis (ALS) disease progression, loss of nuclear trans-acting splicing protein TDP43 leads to accumulation of cryptic exons in mRNAs, which inhibits expression of proteins and aggravates the disease. One of the affected genes is DNAJC5, which codes for a protein responsible for clearance of misfolded proteins in the cytoplasm. We first observed that TDP43 knockdown regulates DNAJC5 transcript splicing. A similar phenotype was observed upon hnRNP K knockdown. We hypothesized canonical splicing of DNAJC5 is dependent on the activity of both TDP43 and hnRNP K. Our results confirmed TDP43 and hnRNP K interaction is dependent on RNA. We also confirmed that DNAJC5 canonical splicing is dependent on its internal TDP43 and hnRNP K binding sites. Taken together, our work enrolls both TDP43 and hnRNP K on splicing regulation of DNAJC5 transcript, affecting activity of the protein encoded by DNAJC5 on endosomal traffic. As a result, activity of both TDP43 and hnRNP K and their association are important for ALS progression.",
"41987571": "ID: 41987571\nTitle: QCatch: a framework for quality control assessment and analysis of single-cell sequencing data.\nAbstract: Single-cell sequencing data analysis requires robust quality control (QC) to mitigate technical artifacts and ensure reliable downstream results. While tools like alevin-fry and simpleaf (and augmented execution context for the alevin-fry), offer flexibility and computational efficiency to process single-cell data, this ecosystem will further benefit from a standardized QC reporting tailored for its outputs. We introduce QCatch, a Python-based command-line tool that generates comprehensive and interactive HTML QC reports designed specifically for single-cell quantification results. Taking the output directory of alevin-fry or simpleaf as the input, QCatch is able to perform essential processing steps, like cell calling, and generate detailed QC reports that contain informative visualizations and statistics, including unique molecular identifier (UMI) count distributions, sequencing saturation estimates, and splicing status information, for QC assurance.

The mechanism(s) that modulates the transition of TDP-43 from a liquid to solid phase is poorly defined. Here we combine chemical and genome-wide genetic screenings to identify cellular factors that modulate the phase behavior of an RNA-binding defective TDP-43 mutant that mimics an Amyotrophic Lateral Sclerosis (ALS)-associated variant. Our screens uncover multiple cellular processes including RNA splicing, protein translation, proteostasis imbalance and nuclear export as TDP-43 phase regulators. Importantly, TDP-43 phase transition can be dynamically recapitulated in vitro in a semi-permeabilized cell system, which reveals that the inhibition of nuclear export reshapes the nuclear environment in favor of an RNA-dependent TDP-43 liquid-liquid phase separation (LLPS) state, which mitigates cytoplasmic TDP-43 aggregation. We validated this mechanism in a brain organoid model bearing an ALS-associated mutation, showing that nuclear export deficiency can limit pathogenic phospho-TDP-43 accumulation. These findings establish nuclear export as a key regulator of TDP-43 phase transitions and define a mechanistic framework that links altered nuclear transport and phase dynamics to TDP-43 aggregation potential.",
"41995061": "ID: 41995061\nTitle: Machine Learning-Driven Ensemble Screening of Multitarget Kinase Inhibitors for Tauopathy-Associated Neurodegeneration Using All-Atom and Steered MD Simulations.\nAbstract: Tauopathies arise when normal functions of the tau protein in axonal transport and neuronal maintenance are disrupted by an imbalance between kinases and phosphatases. Dysregulation of key kinases such as dual-specificity Tyrosine-Regulated Kinase 1A (DYRK1A), Tau Tubulin Kinase 1 (TTBK1), and ABL Proto-Oncogene 1, and Non-Receptor Tyrosine Kinase (ABL1) drives excessive tau phosphorylation and neurofibrillary tangle accumulation. DYRK1A regulates MAPT exon 10 splicing and phosphorylates tau at multiple Ser/Thr residues, priming it for further phosphorylation by other kinases. TTBK1 phosphorylates tau at disease-associated epitopes within the microtubule-binding domain, promoting detachment from microtubules and aggregation. ABL1 phosphorylates tau at tyrosine residues, linking tau modification with A\u03b2-induced synaptic dysfunction. These events collectively drive tau hyperphosphorylation, misfolding, and neurofibrillary pathology characteristic of tauopathies. To identify natural product-derived multitarget inhibitors for these kinases, we developed a comprehensive machine learning (ML) workflow trained on bioactivity data from ChEMBL and BindingDB. We implemented five distinct classifiers: CatBoost, Support Vector Machine (SVM), k-Nearest Neighbors (KNN), Naive Bayes, and XGBoost. Stratified sampling and SMOTE were employed to address class imbalance for DYRK1A and ABL1, while Bemis-Murcko scaffold splitting was used to ensure rigorous evaluation of the data-scarce TTBK1 data set. A soft-voting ensemble model, integrating optimized CatBoost, XGBoost, and SVM, demonstrated superior performance. This robust ensemble was deployed to screen \u223c695,000 natural compounds from the COCONUT 2.0 database. The resulting hits were refined through consensus molecular docking and deep learning-based rescoring (GNINA), leading to the identification of two high-potential lead molecules, CNP0591834.1 and CNP0484145.0. Validation using 1 \u03bcs molecular dynamics simulations confirmed their conformational stability and strong binding affinities. Steered MD further demonstrated their superior mechanical resistance to unbinding, particularly in DYRK1A and ABL1 complexes. Overall, this integrative computational framework highlights these two natural compounds as potent multitarget leads with strong potential to mitigate tau-hyperphosphorylation-driven neurodegeneration.",

Dysregulation of RNA metabolism and splicing has emerged as a central mechanism in ALS pathogenesis. TARDBP (TAR DNA-binding protein), FET family proteins (FUS, EWSR1, TAF15), SOD1 (Superoxide Dismutase 1), and C9orf72 (Chromosome 9 Open Reading Frame 72) are key genes associated with ALS that regulate RNA processing, alternative splicing, and nuclear-cytoplasmic transport. Mutations or mislocalization of these proteins result in nuclear loss-of-function and cytoplasmic gain-of-function toxicity, promoting protein aggregation, sequestering spliceosomal components, and impairing spliceosome assembly. This leads to the aberrant inclusion of cryptic exons in essential neuronal genes, such as STMN2 (Stathmin 2) and UNC13A (Unc-13 Homolog A), resulting in the production of truncated proteins, defective axonal maintenance, and impaired synaptic function. TDP-43 pathology, a hallmark of ALS, disrupts splicing and RNA transport, while C9orf72 repeat expansions and FET protein mutations exacerbate cytoplasmic aggregation and stress granule dynamics. Mutant SOD1 contributes via mitochondrial dysfunction, endoplasmic reticulum stress, and disrupted axonal transport. Therapeutic strategies targeting these mechanisms are advancing rapidly. Gene replacement therapy, which restores STMN2 expression, and antisense oligonucleotides (ASOs) targeting mutant transcripts show promise in preclinical and early clinical studies. Complementary approaches, including the inhibition of stress kinases and the activation of autophagy, reduce cytoplasmic protein aggregation and support neuronal homeostasis. This review provides a comprehensive overview of RNA splicing regulation, spliceosomal dysfunction, and cryptic exon incorporation in ALS. Understanding the interplay among splicing defects, RNA-binding protein pathology, and neuronal degeneration is critical for developing next-generation multimodal therapies to restore RNA processing, reduce toxic protein accumulation, and promote motor neuron survival.",

Their biogenesis, molecular composition, and ability to traverse physiological barriers, including the blood-brain barrier, position exosomes as powerful candidates for biomarker development and therapeutic delivery in neurodegenerative diseases (NDDs). In Alzheimer's disease, Parkinson's disease, multiple sclerosis, and prion disorders, exosomes not only mirror pathological processes but actively participate in the propagation of misfolded proteins and neuroinflammatory signals through cell-type-specific vesicle subpopulations. This review synthesises current advances in exosome biology, cargo sorting, release mechanisms, and pathophysiological roles in the central nervous system, with emphasis on how neuron-, astrocyte-, and microglia-derived exosomes diverge in their cargo profiles and functional consequences across diseases. We highlight disease-specific exosomal signatures, including amyloid-\u03b2 (A\u03b2), tau, \u03b1-synuclein, myelin proteins, prion proteins (PrP) and regulatory microRNAs. We evaluate emerging technologies such as microfluidic isolation, single-vesicle analysis, and multi-omics profiling that are accelerating biomarker discovery, and review exosome-based therapeutic strategies, including native stem cell-derived exosomes and surface-engineered vesicles loaded with neuroprotective miRNAs, small molecules, and gene-editing cargo. We address critical unmet challenges in translating these approaches to the clinic, including scalable and standardised production, incomplete pharmacokinetic /pharmacodynamic characterisation in preclinical models, immunogenicity and off-target safety concerns, and the absence of specific regulatory guidance for EV drug products. Together, these insights highlight the transformative potential of exosomes as both precision diagnostic tools and disease-modifying therapeutic platforms for NDDs.",

This results in the insertion of a 57-nucleotide segment between exon 4 and exon 5, introducing a premature stop codon and leading to a truncated, non-functional \u03b1-Gal A protein. We evaluated whether adenine base editing (ABEmax) can modulate this allele-induced cryptic splice event in patient-derived fibroblasts in vitro as a proof-of-concept. Two ABEmax/sgRNA constructs targeting intron 4 (ABEmax-sgRNA1 and ABEmax-sgRNA2) were tested; both induced on-target +919\u2009A\u2009\u2192\u2009G conversion with frequent bystander edits at +918/+920. Edited bulk populations and single-cell-derived clones showed restoration of correctly spliced GLA mRNA with reduced aberrant transcripts, increased GLA protein, higher \u03b1-Gal A activity (approaching wild-type levels in some clones), and reduced intracellular Gb3 signal. A focused next-generation sequencing panel identified a low-frequency intronic change at one predicted off-target locus without predicted coding consequences. These findings demonstrate in vitro splice rescue of a deep intronic, cardiac-type Fabry disease variant by adenine base editing and suggest that bystander edits in non-coding sequence can further enhance correction by suppressing cryptic splicing, with concordant improvements in \u03b1-Gal A activity and Gb3 signals.",

Dysregulation of mRNA methylation contributes to tumorigenesis and virus replication. However, the association of N1-methyladenosine (m1A) modification with HCC progression and HBV replication remains unclear. Here, single-nucleus RNA sequencing (snRNA-seq) of 4 HCC and 7 adjacent tissues (2 from this study and 5 from the GSE242889) revealed elevated mRNA methylation in HCCs, with increased expression of m1A \"writers\" and \"readers\" and decreased expression of m1A \"erasers\". Among them, m1A writer TRMT6 was up-regulated in HCC and correlated with poor patient prognosis. TRMT6 knockdown strikingly restrained the malignant phenotypes and tumorigenicity of HCC cells as well as HBV replication. Mechanistically, TRMT6-mediated m1A modification enhanced the stability and translation efficiency of cyclin-dependent kinase 9 (CDK9) mRNA. Elevated CDK9 facilitated HCC progression by up-regulating its downstream oncogenic effectors, and stimulated HBV replication via TARDBP phosphorylation at Ser254 to enhance pgRNA transcription and repress pgRNA splicing. CDK9 inhibitor FIT-039 abrogated these effects without obvious toxicity. Thus, TRMT6-mediated m1A modification dually drives HCC malignancy and HBV replication, representing a promising therapeutic target, and CDK9 inhibition may constitute an effective strategy for HBV-related HCC.",

While both loss- and gain-of-function mechanisms contribute to disease, the discovery of cryptic splicing has shed light on the downstream consequences of TDP-43 nuclear clearance for neuronal health. Here, we highlight how loss of nuclear TDP-43 can drive a cascade of events that lead to the impairment of cellular proteostasis and result in a positive feedback loop that perpetuates neuronal dysfunction. This sustains the appearance of cryptic splicing events in genes that are involved in key pathways for the maintenance of axonal homeostasis and synaptic transmission.

Stathmin-2 (STMN2), a tubulin-binding protein essential for axon maintenance and repair, is profoundly depleted following loss of nuclear TDP-43 in neurodegenerative disease. Here, we identify statins as potent inducers of STMN2 expression. Pharmacological and genetic suppression of the mevalonate pathway, and subsequent prevention of protein geranylgeranylation, restored STMN2 levels in TDP-43 deficient cells and promoted neurite growth. STMN2 induction was abrogated when using a statin analogue unable to interact with HMG-CoA reductase, and through co-administration of mevalonate or geranylgeranyl diphosphate substrates. RNA-seq revealed that statins induce a coordinated pro-regenerative transcriptional response, including activation of the AP-1 transcription factor complex gene, ATF3. Loss of ATF3 attenuated STMN2 induction in vitro, and diminished injury-induced Stmn2 upregulation in spinal motor neurons in vivo. These results demonstrate statins as modulators of ATF3 and STMN2 expression and highlight their therapeutic potential in neurodegenerative disease.",

TDP-43 regulates RNA splicing, and its mislocalization leads to cryptic exon inclusion and loss of canonical protein function. While neuronal TDP-43 pathology has been well studied, its role in astrocytes remains less understood. Recent findings suggest increased phosphorylated TDP-43 (pTDP-43) inclusions in astrocytic endfeet in AD and a bidirectional interaction between A\u03b2 and TDP-43, promoting mutual aggregation. We analyzed pTDP-43 immunoreactivity (IR) in astrocytic perivascular end-feet, nuclei, and cytosol in hippocampal sections from 3-month-old and 18-month-old AppNL-F/NL-F mice and 18-month-old wild-type controls using ImageJ. In vitro, primary fetal human astrocytes were exposed to oligomeric A\u03b242, and changes in cytosolic and nuclear pTDP-43 IR were quantified via ImageJ, while TDP-43 and pTDP-43 protein levels were measured using an in-house ELISA. Expression of canonical transcripts ATG4B and KALRN, involved in autophagy and synaptic support, was assessed by qPCR. Corresponding protein-level changes were evaluated using in-house ELISA. Our findings demonstrate significantly higher pTDP-43 accumulations in astrocytic nuclei, cytosol, and endfeet in 18-month-old AppNL-F/NL-F mice compared to age-matched wild-type mice. Astrocytes exposed to oligomeric A\u03b242 showed elevated cytosolic pTDP-43 IR and total pTDP-43 protein levels. Concurrently, expression of canonical ATG4B and KALRN transcripts was significantly reduced, which was accompanied by corresponding decreases in protein levels. Our findings demonstrate that pTDP-43 accumulates in astrocytic nuclei, cytosol, and endfeet in the presence of AD pathology. The observed A\u03b2-induced increase in cytosolic pTDP-43 and transcript disruption suggests a mechanistic link contributing to autophagy impairment and cytoskeletal changes in astrocytes, potentially exacerbating AD progression.",

The variability in disease progression underscores the necessity for tailored diagnostic and therapeutic approaches. MicroRNAs (miRNAs), small non-coding RNAs that regulate gene expression, have emerged as promising biomarkers and therapeutic targets in ALS. Dysregulation of specific miRNAs has been linked to mechanisms of ALS, including neuromuscular dysfunction, neuroinflammation, and neuronal survival/apoptosis. The potential of miRNA-based therapies, such as mimics and inhibitors, offers a more integrated approach by modulating entire disease networks, rather than targeting isolated pathways. However, challenges persist, particularly in delivering these therapies efficiently across the blood-brain barrier and minimizing off-target effects. Current delivery strategies involving nanoparticles, viral vectors, and exosome-based approaches require optimization for clinical use. This review synthesizes the latest research on miRNA-mediated mechanisms in ALS, evaluating their diagnostic, prognostic, and therapeutic potential, while highlighting the current limitations in clinical validation. It underscores the importance of standardized methodologies, multi-omics integration, and rigorous validation to facilitate the clinical translation of miRNA-based strategies. Standardized protocols and multicenter validation in large cohorts are essential to confirm the diagnostic accuracy of miRNAs, paving the way for their clinical application in ALS precision medicine.",

Despite recent advancements in amyloid-beta-targeting immunotherapies, achieving safe and definitive disease control remains a profound clinical challenge. The CRISPR/Cas9 system has emerged as a powerful technology for precision neurogenetics, offering significant potential to address the fundamental questions behind Alzheimer's disease. This comprehensive review delineates the trajectory of CRISPR applications in Alzheimer's disease research and therapeutics. First, we explore the integration of CRISPR in engineering high-fidelity in vitro models, such as isogenic induced pluripotent stem cells and three-dimensional cerebral organoids, alongside advanced in vivo mammalian models. Second, we examine how these platforms facilitate unbiased high-throughput genetic screening to uncover molecular underpinnings regulating tau, lipid metabolism, and neuroinflammation. Third, we critically evaluate precision editing strategies targeting core risk genes (APP, MAPT, APOE, and TREM2), explicitly highlighting the severe physiopathological trade-offs between therapeutic efficacy and loss-of-function toxicity. Finally, we address the ultimate translational bottlenecks impeding clinical application. By dissecting the packaging limits of adeno-associated viral vectors and the physical barricade of the blood-brain barrier, we underscore the necessity of transitioning toward next-generation base editors and non-viral lipid nanoparticles to realize safe and efficacious in vivo clinical gene therapies against Alzheimer's disease.",
"42074341": "ID: 42074341\nTitle: Pompe Disease: Pathogenesis, Molecular Mechanisms, Neurological Aspects, Diagnostics and Modern Therapeutic Approaches.\nAbstract: Pompe disease (PD) is a neuromuscular autosomal recessive disorder caused by mutation in the GAA gene, which encodes acid \u03b1-glucosidase (GAA), an enzyme responsible for hydrolyzing glycogen to glucose. Deficiency of this enzyme leads to pathological accumulation of glycogen in almost all tissues of the body, with the most pronounced effects in cardiac and skeletal muscle, as well as in the central nervous system. Two major clinical forms of PD are recognized: infantile-onset PD, characterized by almost complete absence of GAA activity and severe cardiomyopathy and neurological abnormalities, and late-onset PD, which primarily presents with impairment of respiratory and motor function. Since 2006, enzyme replacement therapy with recombinant GAA has been used to treat PD, improving survival and quality of life. However, this approach has several limitations: the need for lifelong infusions, the risk of immune responses, and the inability of the enzyme to cross the blood-brain barrier, which is particularly critical for infantile-onset PD. Consequently, alternative strategies are being developed, including gene therapy using adeno-associated virus vectors for GAA delivery to target tissues; these approaches are currently in phase I/II clinical trials. Transplantation of genetically modified hematopoietic stem cells also represents a promising therapeutic strategy, offering a single-intervention treatment with long-lasting effects. This review discusses the molecular mechanisms of PD, current and emerging disease models, and therapeutic approaches, which together open prospects for the development of potentially one-time curative treatments, despite persistent challenges such as immunogenicity and the need for long-term efficacy monitoring.",

However, its yields are hindered by various factors, including diseases such as leaf blight caused by Exserohilum turcicum. In this study, field phenotypes were analyzed on 102 accessions (including checks SC748-5 and BTx623) grown and evaluated at two locations in Niger for leaf blight incidence and severity. The panel included accessions originally collected from Niger and Senegal. Genotypes were generated for 120 accessions, and GWAS/ML analyses were performed on 102 accessions due to missing phenotypic data. Among the accessions, S39, N23, and N38 exhibited mean leaf blight incidence below 50%, while S3, S43, N23, and N38 displayed the lowest severity levels, with a mean severity in Niger of 24.5 \u00b1 0.64. Accession N23 showed relatively low incidence and severity levels across the Niger field evaluations. Using genome-wide association studies and machine learning, candidate SNPs associated with leaf blight phenotypes were identified. Genes near these SNPs were associated with functions related to plant defense mechanisms and stress responses, providing preliminary targets for future validation in sorghum leaf blight studies.",

The existing therapies have only a small effect on alleviating symptoms, mainly because the therapeutic agents are difficult to cross the bloodbrain barrier. The purpose of the review is to discuss the potential of microneedle-based transdermal delivery systems to improve the delivery of drugs to the central nervous system and thereby manage neurodegenerative diseases effectively. The article summarizes and synthesizes the available literature that targets the strategies of microneedle-mediated drug delivery. The literature on the design, composition, pharmacokinetics, and mechanistic benefits of different microneedle platforms for surmounting central nervous system barriers was identified and thematically synthesized. Microneedle systems have emerged as non-invasive delivery systems with the potential for localized and sustained drug delivery, overcoming the stratum corneum and the blood-brain barrier. Micro-needles can be used to deliver small molecules, peptides, and nanoparticles to the brain, thereby avoiding systemic side effects and enhancing drug bioavailability. Some of those designs include dissolving, coated, hollow, hydrogel-forming, and stimuli-responsive microneedles, which have been shown to target the brain and exhibit higher therapeutic efficiency in preclinical models. Although technological advances have improved, the clinical translation of microneedlebased strategies remains limited. The future directions could include using microneedles with stem cell-based therapies, CRISPR/Cas9 gene editing, artificial intelligence-based delivery systems, and responsive release technology to facilitate customized treatment. The Microneedle-based drug delivery systems are promising in overcoming the current limitations in the treatment of neurodegenerative diseases. Nonetheless, a large-scale clinical validation is necessary to guarantee safety, efficacy, and scalability to be applied to real-life scenarios.",

Accumulation of DNA damage is emerging as a novel correlative trait of ALS. We recently showed that formation of TDP-43 and FUS cytoplasmic inclusions (CIs) lead to DNA damage accumulation through dysregulation of the DNA damage response (DDR). However, the multiple molecular mechanisms contributing to DNA damage accumulation in affected motor neurons in ALS have not been fully elucidated. In recent years, chemical inhibition of the serine/threonine kinase CHK1 was shown to lead to accumulation of DNA breaks as well as increased apoptosis, in differentiated cortical neurons. Notably, CHK1 has been involved in DNA double-strand break repair in non-dividing cells, by acting through the histone chaperone ASF1A. In this article, we show that cells bearing FUS and TDP-43 CIs show downregulation of the protein levels of CHK1 and ASF1A. We observe CHK1 protein downregulation in neuronal cell lines, as well as in patient-derived motor neurons progenitors and in the spinal cord of a FUS-ALS mouse model. Restoration of the nuclear levels of CHK1 and ASF1A via transient overexpression, is sufficient to reduce DNA damage signal accumulation and rescues DDR defects. Importantly, we show that the ubiquitin-proteasome pathway is responsible for CHK1 degradation in cells bearing FUS CI, since its inhibition restores CHK1 and ASF1A protein levels. Our study demonstrates that proteasomal-dependent CHK1 and ASF1A downregulation contributes to accumulation of DNA damage in cells affected by ALS-linked protein aggregates.",

It is characterized by severe immune dysregulation, with gasdermin D (GSDMD)-driven pyroptosis recognized as a key pathogenic mechanism. After exposure to pathogen-associated molecular patterns (PAMPs)/damage-associated molecular patterns (DAMPs), GSDMD, activated via the canonical (caspase-1) and non-canonical (caspase-4/5/11) pathways, forms plasma membrane pores, induces cell lysis, and triggers multi-organ injury. Specifically, GSDMD pores trigger lung inflammation via alveolar macrophage pyroptosis, induce hepatic high mobility group box 1 protein (HMGB1) release, perpetuate bacteremia, cause renal microthrombosis, and disrupt the blood-brain barrier. GSDMD drives both the hyperinflammatory phase (via cytokine storm, NETosis) and the immunosuppressive phase (via lymphocyte apoptosis, T-cell exhaustion), thereby defining hyperinflammatory (GSDMD-NT >120 ng/mL) and immunosuppressive (intestinal barrier failure) endotypes. Promising therapeutic agents include disulfiram (blocking Cys191 oligomerization), anti-GSDMD mAb26.5 (decreasing mortality to 30%), and the combination of imipenem and disulfiram. Clinical translation faces challenges in terms of biomarker validation, organ-specific delivery, and phase-adapted intervention. Future research directions include AI-based drug design, exosome-mediated CRISPR knockout, clinical trials on drug repurposing, and single-cell omics-integrated stratified immunotherapy.",

In this work, we define how short, specific RNAs solubilize TDP-43. These short RNAs engage and stabilize the TDP-43 RNA recognition motifs, which allosterically destabilizes a conserved helical region in the prion-like domain, thereby promoting aggregation-resistant conformers. Sequence-space mining identified short RNA chaperones with enhanced activity against TDP-43 and disease-linked variants. Enhanced short RNA chaperones mitigated aberrant TDP-43 phenotypes in optogenetic models and in ALS patient-derived and control motor neurons. In mice with cytoplasmic TDP-43 aggregation and motor neuron loss, an enhanced short RNA chaperone reduced pathological aggregation, restored TDP-43 function, and conferred neuroprotection. These results define a mechanistic and therapeutic framework for RNA-based strategies to counter TDP-43 proteinopathies.",

Although PCR-based assays are highly sensitive, their reliance on centralized laboratory infrastructure limits accessibility in decentralized settings. CRISPR-Cas diagnostics combined with lateral flow assays (LFA) offer a rapid alternative; however, visual interpretation of faint test bands remains subjective and variable. Here, we developed a smartphone-based CRISPR-Cas12a LFA platform integrated with an interpretable machine learning (ML) framework for quantitative detection of circulating HPV DNA in plasma. Standardized image acquisition was implemented using a light-controlled enclosure, and radiomics-inspired features were analyzed using a multivariable logistic regression model. The system was trained on 150 plasma samples and validated in an independent cohort of 60 samples. The optimized model achieved 96.7% sensitivity and 100% specificity, outperforming visual interpretation, particularly for low-signal samples. Performance remained stable across different smartphone models, lighting conditions, and operators, with rapid on-device inference enabling consistent and reliable operation. This integrated CRISPR-LFA platform demonstrates accurate and reproducible detection of circulating HPV DNA and supports feasibility for POC applications, pending further validation in broader clinical settings.",

However, the blood-brain barrier (BBB) poses a significant challenge to the effectiveness of gene editing components in the affected brain region and impedes clinical translation. This comprehensive review compares various CRISPR-Cas9 delivery vectors, viral, nonviral and physical, with a focus on their efficacy in neurological diseases such as AD. Viral vectors viz., adeno-associated viruses (AAVs) and lentiviruses (LVs) demonstrate high transduction efficiency and BBB permeability. AAVs are preferred for their low immunogenicity, minimal toxicity, high neuronal tropism and episomal persistence, enabling sustained expression without insertional mutagenesis. LVs offer larger genetic payloads but raise concerns about genomic integration and potential oncogenesis, though integration-defective variants mitigate these risks. Nonviral vectors, including peptide and polymer-based nanoparticles, lipid nanoparticles (LNPs) and Inorganic carriers such as gold and silver nanoparticles, are less immunogenic and easier to handle but require further optimisation for in\u00a0vivo BBB crossing and endosomal escape. Physical methods such as electroporation and microinjection are suitable for in\u00a0vitro/ex vivo use, while novel CNS-targeted strategies, such as RVG-tagged particles, TfR-directed LNPs and engineered AAV variants, enhance brain penetration via receptor-mediated transcytosis. These preclinical studies show that these technologies can successfully edit genes and provide therapeutic benefits, including amyloid reduction and cognitive improvement in AD models. Yet off-target effects, immune responses and regulatory hurdles persist. Overall, continuous innovation in delivery vector design and safety profile-targeting strategies is crucial for advancing CRISPR-Cas9 towards clinical therapies for AD-based therapies and related neurological disorders.",

We emphasize conserved pathogenic modules, including oxidative stress, mitochondrial dysfunction, impaired proteostasis, and stress signaling through Nrf2, JNK, and PINK1/Parkin, and distinguish robust mechanistic insights from findings that are primarily descriptive or overexpression-driven. We further discuss the specific contribution of Drosophila genetic tools such as GAL4/UAS, RNA interference, CRISPR-Cas9, and FLP/FRT-based mosaic analysis for dissecting cell-autonomous and non-cell-autonomous neurotoxicity. To improve usability, the manuscript now summarizes major disease models and natural compounds in dedicated tables, expands therapeutic discussion to include HDAC inhibitors and mitochondria/redox-directed small molecules, and outlines how fly studies can function within translational pipelines for variant interpretation, target prioritization, and preclinical triage before mammalian validation and human trials. Finally, we address key limitations of Drosophila relative to humans, including differences in metabolism, blood-brain barrier properties, immune complexity, and disease timescale, to provide a more balanced framework for using fly neurodegeneration models in precision medicine.",

Conversely, gene regulatory network (GRN) inference methods largely neglect the dynamic nature of biological systems. To overcome this conceptual disconnect, we present RegVelo, a bottom-up, actionable, and interpretable deep learning framework that jointly models splicing kinetics and gene regulatory interactions. Across diverse biological systems, RegVelo provides reliable predictive power for terminal states, gene interactions, and perturbation simulations. By applying RegVelo to zebrafish neural crest development using full-length Smart-seq3 and shared gene expression and chromatin accessibility measurements, we delineate regulatory programs underlying fate specification. Guided by in silico perturbations and validated by CRISPR-Cas9 knockout and single-cell Perturb-seq, we establish tfec as an early driver and elf1 as a regulator of pigment cell fate. RegVelo establishes a quantitative framework for bridging gene regulation and cell fate decisions.",

Conventional culture-based methods are limited by prolonged turnaround times, reduced sensitivity in patients receiving prior antimicrobial therapy, and restricted ability to characterize resistance mechanisms at the molecular level. Molecular diagnostic technologies have significantly transformed bacteriological diagnostics by enabling rapid, sensitive, and specific pathogen detection directly from clinical specimens. This review provides a structured comparative analysis of major molecular platforms, including polymerase chain reaction (PCR) and its variants, isothermal amplification technologies, next-generation sequencing (NGS), clustered regularly interspaced short palindromic repeats (CRISPR) based diagnostics, and digital PCR (dPCR). Key analytical parameters such as sensitivity, specificity, limit of detection (LOD), time to result, and multiplexing capacity are evaluated to highlight platform-specific strengths and limitations. In addition, the integration of artificial intelligence and machine learning (AI/ML) into molecular diagnostic workflows for AMR prediction and clinical decision support is critically examined. The translational potential of these technologies toward point-of-care (POC) implementation is also discussed, with consideration of clinical validation, operational constraints, and real-world applicability.

"42123994": "ID: 42123994\nTitle: Long-Chain Fatty Acids as Drivers of Neuroinflammation in Neurodegeneration: Mechanistic Links to Lipid Peroxidation, Ferroptosis, and Mitochondrial Dysfunction.\nAbstract: Background: Neurodegenerative diseases (NDs) are mainly considered disorders marked by severe immunometabolic imbalance, characterized by ongoing neuroinflammation and glial activation. While mitochondrial dysfunction and oxidative stress are well-known features, the upstream metabolic factors linking these pathological processes remain poorly understood. Methods: In this review, we examined recent preclinical and clinical studies exploring the connections between lipid metabolism, glial immunometabolism, and regulated cell death pathways. Our focus was on how long-chain fatty acids (LCFAs) facilitate communication among mitochondria, reactive oxygen species (ROS), and ferroptosis in Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS). Results: New evidence shifts LCFAs from merely being passive indicators of cellular damage to active, upstream regulators of the neuroimmune response. Existing research shows that excess LCFA intake can overload astrocytic mitochondrial oxidative phosphorylation, leading to abnormal lipid droplet buildup and reactive astrogliosis. This lipid-driven reactivity promotes microglial polarization toward a persistent pro-inflammatory state. Notably, high levels of specific LCFAs, especially arachidonic acid, increase ROS production and lipid peroxidation. This lipotoxic environment ultimately triggers ferroptosis, an iron-dependent form of cell death shared across multiple NDs. Conclusions: The harmful interaction among mitochondrial dysfunction, lipid peroxidation, and ferroptosis is driven by an imbalance in LCFA levels. Addressing current challenges, such as the complex effects of polyunsaturated fatty acid supplementation, requires advanced techniques like single-cell multi-omics and artificial intelligence. Understanding this intricate lipidomic-transcriptomic crosstalk is crucial for moving toward personalized neuroimmunometabolism and developing new treatments to prevent ferroptosis.",

However, conventional detection methods and equipment are often unsuitable for the on-site and timely monitoring of these pathogens. To overcome this critical limitation and establish a rapid detection workflow, we developed the portable smart Ai BOX (artificial intelligence BOX). This device is a compact, palm-sized, internet of things (IoT)-enabled instrument that utilizes isothermal fluorescence diagnostics and weighs only 180 g. The Ai BOX features an optimized minimalist industrial design, ultralow power consumption, and a high-sensitivity optical sensing system. The device performs real-time fluorescence detection, with results automatically interpreted and transmitted to a dedicated mobile application (APP) via an integrated smart camera, enabling comprehensive food monitoring. Furthermore, the incorporation of artificial intelligence and machine learning (ML) algorithms significantly enhances the processing capability of the RPA-CRISPR/Cas12a fluorescence signal, thereby ensuring superior detection accuracy. The Ai BOX is ideally suited for on-site point-of-care testing (POCT) of foodborne pathogens.

RNA velocity analysis infers the temporal dynamics of transcriptional states from the relative abundances of spliced/unspliced mRNA quantified via scRNA-Seq.\u00a0Classical RNA velocity approaches, such as scVelo, implement gene-specific kinetic modeling. Deep learning methods including DeepVelo, VeloVI, LatentVelo, SymVelo, and scTour are based on variational autoencoders (VAEs), which allow to enhance the robustness and accuracy by leveraging nonlinear latent representations. Here, we systematically evaluated the performance of deep learning RNA velocity tools by comparing with the scVelo dynamical model to access the possible advantages of VAE-base methods. For this purpose, public datasets (GSE149689 and GSE203233) were initially processed using a standard scRNA-Seq pipeline. Comparisons among results of selected velocity tools were conducted using cosine similarity of velocity vectors to assess directional concordance, and by mean squared error analysis of trajectory continuity for the deep learning models. Overall, VAE methods produced significant, richer, and more directionally coherent and consistent velocity fields than the classical model. Our findings indicate that deep learning models provide more consistent and biologically plausible cell-state trajectories, although at the expense of higher computational demands and reliance on accurate splicing quantification. Altogether, our results underscore the relevance of VAE-based frameworks to advance RNA velocity analysis while highlighting the need for careful preprocessing.",

While open-source implementations have been published with author-reported comparisons, independent benchmarking across diverse datasets is needed to establish equivalence. We compared the original SpliceAI with two open-source implementations (OpenSpliceAI and CI-SpliceAI) and a legacy ensemble baseline across six datasets: a curated set of 1,316 validated variants, 213 variants with splice-assay data, 99,601 variants from the SPiP splicing prediction study, 242 manually curated deep intronic pathogenic variants, and two ClinVar-derived datasets comprising 53,600 intronic variants and 58,064 variants spanning all genomic contexts. The deep learning models were also evaluated against an ensemble of four legacy splice-prediction tools. Across all datasets, the deep learning algorithms outperformed the legacy ensemble. All three deep learning algorithms showed similar performance on the larger datasets dominated by canonical splice site variants (balanced accuracies 0.889-0.977). On the deep intronic benchmark, the original SpliceAI achieved the highest balanced accuracy (0.940), outperforming both CI-SpliceAI (0.890) and OpenSpliceAI (0.841). Critically, optimal thresholds for deep intronic variants were an order of magnitude lower than standard recommendations, indicating that default thresholds would miss the majority of pathogenic deep intronic variants. A correlation analysis showed that CI-SpliceAI maintained balanced concordance across event types, whereas OpenSpliceAI showed stronger correlation for loss events than gain events. Both implementations showed high positional agreement with SpliceAI, with exact splice-site match rates exceeding 90% across event types. Together, these results demonstrate that both open-source reimplementations of SpliceAI successfully reproduce the predictive behavior of the original algorithm across multiple evaluation contexts, while consistently outperforming traditional splice prediction methods. However, performance diverges on deeply intronic variants, and standard score thresholds are poorly calibrated for this variant class regardless of algorithm choice.",

Although its treatment strategy has gradually developed from traditional chemotherapy to a multimodal treatment system including novel targeted therapy and immunotherapy, primary drug resistance in particular remains the core clinical problem leading to poor patient prognosis. This clinical dilemma indicates that the traditional genotyping system based on genomics has not been able to fully resolve the molecular heterogeneity of acute myeloid leukemia (AML), and it is urgent to establish a precise stratified model that can dynamically reflect the functional status of tumor cells in the initial stage of treatment. In this study, Raman spectroscopy (RS) combined with machine learning algorithm was used to construct a metabolic prognosis prediction model for AML chemotherapy response. Bone marrow single cell Raman spectroscopy data of newly diagnosed AML patients were collected, and the molecular fingerprint was analyzed by principal component analysis linear discriminant analysis (PCA-LDA) and multivariate curve resolute alternating least square method (MCR-ALS). The results showed that the PCALDA model achieved complete remission or non-remission (CR/NR) classification through 24 principal components (cumulative variance contribution of 90.1%), the accuracy of external validation was 94.8% (sensitivity 97.9%, specificity 92.0%), and the AUC reached 96.27%. Protein, lipid, nucleic acid and mixed components were decomposed by MCR-ALS, and lipid and nucleic acid metabolic pathways were enriched in NR group (P < 0.001).

However, the upstream regulators that could be targeted for therapeutic intervention remain poorly defined. This study identifies gamma-glutamyl transferase 1 (GGT1) as a key driver of ferroptosis, upregulated in neurons post-SCI. Screening a 150-compound natural product library, we discovered Enocyanin (EA), which reduced GGT1 protein levels, protected neurons from hypoxic injury, and exhibited anti-ferroptotic effects. Mechanistically, EA promoted GGT1 degradation through the E3 ligase MGRN1, leading to K48-linked polyubiquitination and proteasomal clearance, halting ferroptosis. To improve EA's stability and delivery, we engineered a biomimetic nanoplatform (NSCm@EA) using neural stem cell membranes, enhancing drug accumulation at the injured spinal cord. At single-cell resolution, NSCm@EA was shown to precisely remodel neuronal subpopulations, selectively expanding \u03b3-motor neurons and upregulating synaptic genes such as Gria2 and Negr1, while suppressing inflammatory and oxidative stress pathways. In summary, this study reveals GGT1's role in ferroptosis, identifies a natural product that induces its ubiquitin-mediated degradation, and presents a targeted biomimetic delivery strategy for precise intervention in spinal cord injury.",

Methodologically, this work integrates a narrative synthesis of the literature with an in-silico bioinformatic analysis of bulk (GTEx) and single-cell (HPA, CellxGene) RNA-seq datasets, aiming to clarify how mGluRs contribute to testicular physiology. After outlining the striking structural and metabolic parallels between brain and testis-tight barrier systems, selenium-dependent redox control, and exceptionally complex alternative splicing-we confirm that several mGluR subtypes are expressed in Sertoli, Leydig, and germ cells. GRM7 and GRM8 emerge as the dominant transcripts during the late stages of spermatogenesis, and their co-expression networks are strongly linked to axoneme assembly, cilium-driven motility, mitogen-activated protein kinase (MAPK) signaling, and spermatid differentiation. These results point to a role for mGluR-dependent, cyclic adenosine monophosphate (cAMP)-sensitive pathways in fine-tuning sperm maturation and motility. We further discuss how mGluR activity interfaces with the hypothalamic- pituitary-gonadal (HPG) axis and local estrogen signaling, highlighting implications for male infertility, novel contraceptive strategies, and the safe therapeutic targeting of mGluRs in neuropsychiatry.

Although neuroinflammation is increasingly recognized as a hallmark of ALS, the precise molecular programs linking immune responses to MN pathology remain poorly defined. Using an integrated approach that combines single-cell and bulk RNA sequencing with spatial proteogenomics, we characterized both shared and distinct immune dynamics in peripheral blood and spinal cord tissues from patients with sporadic ALS and those carrying C9orf72 repeat expansions. Our analysis revealed broad immune remodeling in C9orf72 ALS, ALS subtype-specific and progression-associated differences in monocyte activation and antigen-experienced CD8 effector memory T cells with clonal features consistent with antigen-driven responses. Spatial mapping revealed complement activation and lipid-programmed myeloid states converging at sites of MN loss and TDP-43 pathology. Together, these findings connect peripheral and central immune alterations to ALS heterogeneity and highlight stratified immunomodulation as a potential therapeutic strategy.",

While its cytoplasmic aggregation is the pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD), recent evidence suggests that the earliest pathogenic event is the disruption of its physiological homodimeric structure. Under healthy conditions, TDP-43 forms dimers via its N-terminal domain, a configuration that is crucial for its nuclear solubility and cooperative RNA binding. In this review, we propose the \"Molecular Zipper\" hypothesis to describe the maintenance of TDP-43 structural homeostasis. In this framework, the N-terminal domain acts as a stabilizing \"NTD-mediated anchor\" that keeps the protein in a functional, \"zipped\" dimeric state, effectively sequestering its aggregation-prone C-terminal regions. Pathogenic triggers-including genetic mutations, aberrant post-translational modifications such as phosphorylation and acetylation, and environmental stressors-can \"unzip\" this structure, leading to the formation of pathogenic monomers. These pathogenic monomers show increased propensity for cytoplasmic mislocalization and recruit wild-type protein into aggregates through a prion-like seeded aggregation mechanism, culminating in nuclear functional loss and cytoplasmic gain-of-toxicity. We further evaluate the emerging diagnostic landscape, focusing on methods to monitor the dimer-to-monomer ratio. Integrating prior biochemical data on TDP-43 dimerization with structural modeling enables a more coherent account of the transition from the physiological dimer to pathological conformers. The Molecular Zipper framework offers a conceptual foundation for reconciling existing experimental findings and for guiding future studies on early structural changes in TDP-43 proteinopathy.",
"42135847": "ID: 42135847\nTitle: TDP-43: [GU]-ardian of the transcriptome.\nAbstract: TDP-43 is a ubiquitously expressed, primarily nuclear DNA/RNA-binding protein implicated in neurodegenerative diseases including amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD). In this review, we examine the structure and regulation of TDP-43, how these features influence its localization and functional activity, and how their disruption may contribute to disease. Among TDP-43's diverse functions, splicing repression of nonconserved RNA sequences termed cryptic exons has emerged as especially central to human disease. TDP-43 nuclear depletion and cytoplasmic aggregation are well-established pathological features in affected neurons and glia of neurodegenerative diseases, and accumulating evidence suggests that loss of TDP-43-mediated splicing repression occurs presymptomatically in disease. Advances in RNA-sequencing have enabled systematic identification of cryptic exon inclusion as a sensitive marker of TDP-43 dysfunction. Here, we synthesize current knowledge of TDP-43 biology and curate datasets from human tissues and experimental models, focusing on cryptic splicing to provide a resource for leveraging cryptic exon biology to better understand, detect, and target TDP-43 dysfunction.",

One significant challenge in the treatment of these conditions is the Blood- -Brain Barrier (BBB), a highly selective interface that limits the access of most therapeutic molecules to the central nervous system. Nanotechnology has become an attractive approach to addressing this difficulty, as it enables the delivery of drugs with high accuracy and actively engages in the repair of the BBB. This review provides an overall synthesis of focused nanotechnology solutions aimed at both circumventing and restoring BBB function in neurodegenerative illnesses. It discusses various nanoparticle (NP) platforms such as polymeric, lipid-based, micellar, metallic, and carbon-derived systems in the light of their physicochemical aspects, transport across the BBB, and therapeutic efficacy. Particular emphasis is put on the receptor-mediated transcytosis, neurovascular unit modulations, and the regulation of Wnt, Shh, and Tie-2 signalling pathways, which are BBB integrity pathways. The review incorporates mechanisms of BBB repair in combination with neuroprotective nanotherapies, rather than focusing solely on end repair. This review covers the role of targeted nanotechnology in the future of therapeutic approaches for neurodegenerative diseases. By connecting materials science, molecular neuroscience, and clinical innovation, it demonstrates how next-generation brain-targeted therapies can be developed using targeted nanotechnology.",

Among the 15 serotypes, serotypes 2, 5, and 12 represent globally disseminated, high-risk lineages characterized by increased virulence and antimicrobial resistance (AMR). To systematically investigate the global epidemiology and molecular basis of high-risk serotypes, we conducted a large-scale comparative genomic analysis. We assembled 1,004 G. parasuis genomes, including 102 newly sequenced isolates from diseased swine across 18 Chinese provinces and 902 publicly available genomes from 16 countries. Pan-genome analysis identified msmX as a novel marker for precise serotype 5/12 differentiation. Bayesian phylogeographic reconstruction then traced the dissemination history of these lineages: a highly antimicrobial-resistant lineage of serotype 2 likely originated in Japan and spread to the Americas via China in the late 1940s, whereas highly virulent lineages of serotypes 5 and 12 emerged in China before dispersing globally. Resistome and virulome profiling revealed distinct risk patterns: serotype 2 isolates carried more antimicrobial resistance genes (ARGs), while serotypes 5 and 12 harbored broader repertoires of virulence factors (VFs). Notably, we identified isolates co-harboring extensive suites of both VFs and ARGs, representing a convergent dual high-risk genomic profile. Furthermore, machine learning models identified signature genes significantly associated with AMR and virulence, which are implicated in pathways, such as cell wall synthesis, capsular polysaccharide production, and carbon source utilization. Taken together, these findings elucidate the global dissemination patterns and molecular foundations of high-risk serovars and provide critical evidence to guide targeted surveillance, clinical antimicrobial stewardship, and rational vaccine development.IMPORTANCEGlaesserella parasuis poses a global threat to swine health, with serovars 2, 5, and 12 representing high-risk lineages due to enhanced virulence and antimicrobial resistance. However, their global spread patterns and genetic basis remain poorly resolved. Through large-scale comparative genomics of 1,004 isolates, we resolved the transcontinental dissemination routes of these lineages and identified msmX as a novel marker to distinguish serotypes 5 and 12. We further uncover high-risk clones co-carrying extensive virulence and resistance gene repertoires. This study provides a population genomic framework for monitoring high-risk G. parasuis strains and informs the development of targeted vaccines and stewardship strategies to mitigate their impact.",

Mitochondria and lysosomes interact via signaling and membrane contacts to maintain cellular homeostasis. Mitochondrial-derived peptide MOTS-c, encoded by the MT-RNR1/12S rRNA open reading frame, enhances mitochondrial function by reducing reactive oxygen species (ROS) and stabilizing the membrane potential, potentially preserving lysosomal integrity and reducing lysosomal membrane permeabilization (LMP). This study investigated the protective effects and underlying mechanisms of MOTS-c in ischemic flaps. RNA sequencing explored MOTS-c mechanisms in ischemic flaps. Tissue clearing, laser speckle contrast imaging and Doppler analyses revealed improved blood flow perfusion following MOTS-c treatment. Histological staining (HE, Masson, F-CHP) demonstrated enhanced angiogenesis and collagen remodeling. Western blotting, ELISA, and immunofluorescence were used to assess pyroptosis, macroautophagy/autophagy, LMP, and MAPK1/ERK2-MAPK3/ERK1-NFKB/NF-\u03baB pathway-related proteins. MOTS-c reduced endothelial pyroptosis, enhanced autophagy, and attenuated LMP in ischemic flaps. Mechanistically, in vivo overexpression of PLA2G4A/cPLA2 (phospholipase A2, group IVA (calcium, calcium dependent)) via AAV confirmed that MOTS-c enhances autophagy and reduces pyroptosis and LMP by suppressing PLA2G4A phosphorylation. Furthermore, MOTS-c inhibited PLA2G4A via the MAPK1-MAPK3-NFKB signaling cascade, thereby reducing LMP and enhancing flap survival. These findings suggest that MOTS-c restores cellular homeostasis by targeting the PLA2G4A-LMP axis, representing a promising therapeutic strategy for improving outcomes in ischemic flap surgery.Abbreviations: AA\u2009=\u2009arachidonic acid, AAV\u2009=\u2009adeno-associated virus, ACTA2/\u03b1-SMA\u2009=\u2009actin alpha 2, smooth muscle, aorta, ALs\u2009=\u2009autolysosomes, BECN1\u2009=\u2009beclin 1, CASP1\u2009=\u2009caspase 1, CQ\u2009=\u2009chloroquine, CTSB\u2009=\u2009cathepsin B, CTSD\u2009=\u2009cathepsin D, CTSL\u2009=\u2009cathepsin L, Co-IP\u2009=\u2009co-immunoprecipitation, DEGs\u2009=\u2009differentially expressed genes, ELISA\u2009=\u2009enzyme-linked immunosorbent assay, F-CHP\u2009=\u20095-FAM-conjugated collagen hybridizing peptide staining, GSDMD\u2009=\u2009gasdermin D, GO\u2009=\u2009gene Ontology, GPT/ALT\u2009=\u2009glutamic pyruvic transaminase, soluble, GOT1/AST\u2009=\u2009glutamic-oxaloacetic transaminase 1, soluble, HE\u2009=\u2009hematoxylin-eosin, HUVECs\u2009=\u2009human umbilical vein endothelial cells, IP/MS\u2009=\u2009immunoprecipitation coupled with mass spectrometry, IL1B/IL-1\u03b2\u2009=\u2009interleukin 1 beta, IL18\u2009=\u2009interleukin 18, IP\u2009=\u2009intraperitoneal injection, IV\u2009=\u2009intravenous injection, LDBF\u2009=\u2009laser Doppler blood flow, LMP\u2009=\u2009lysosomal membrane permeability, MAP1LC3/LC3\u2009=\u2009microtubule-associated protein 1 light chain 3, MAPK\u2009=\u2009mitogen-activated protein kinase, NAGLU\u2009=\u2009alpha-N-acetylglucosaminidase (Sanfilippo disease IIIB), NFKB/NF-\u03baB\u2009=\u2009nuclear factor kappa B, NLRP1\u2009=\u2009NLR family pyrin domain containing 1, NLRP3\u2009=\u2009NLR family pyrin domain containing 3, PECAM1/CD31\u2009=\u2009platelet/endothelial cell adhesion molecule 1, PLA2G4A/cPLA2\u2009=\u2009phospholipase A2, group IVA (cytosolic, calcium-dependent), PYCARD/ASC\u2009=\u2009PYD and CARD domain containing, PIK3C3/VPS34\u2009=\u2009phosphatidylinositol 3-kinase catalytic subunit type 3, PMA\u2009=\u2009phorbol 12-myristate 13-acetate, ROS\u2009=\u2009reactive oxygen speciesSQSTM1/p62\u2009=\u2009sequestosome 1, SPR\u2009=\u2009surface plasmon resonance, scRNA-seq\u2009=\u2009single-cell RNA sequencing, UMAP\u2009=\u2009uniform manifold approximation and projection, WB\u2009=\u2009western blotting.",

However, traditional step-wise DE is constrained by limited screening throughput. To more efficiently navigate epistatic fitness landscapes, the field is increasingly adopting autonomous, continuous in vivo evolution systems. This review critically examines the molecular architectures and engineering principles driving this transition. We evaluate strategies for continuous genetic diversification-ranging from orthogonal replication systems (e.g., OrthoRep, T7-ORACLE) to CRISPR-guided mutagenesis (e.g., EvolvR)-with a focus on the fundamental trade-off between mutational load and host viability. Furthermore, we analyze the biophysical constraints of screening and the kinetic demands of coupling real-time selection with ultra-fast mutagenesis, as exemplified by phage-assisted continuous evolution (PACE). Crucially, we explore the functional integration of machine learning (ML), highlighting how active learning models and zero-shot predictions via protein language models (PLMs) can resolve epistatic complexities and mitigate the latency of next-generation sequencing. Finally, we discuss the multidimensional hardware and algorithmic bottlenecks currently impeding the realization of fully closed-loop biofoundries, and assess the strategic implications of these technologies for accelerating the engineering of complex therapeutics.",

Here, to address this, we developed HELIX, a hierarchical deep learning framework that integrates pre-mRNA sequence and RNA-binding protein expression profiles to predict tissue- and condition-specific splicing patterns and transcript isoform usage simultaneously. By leveraging both short-read and long-read RNA sequencing data during training, HELIX achieves greater accuracy than existing splicing prediction models and conventional short-read-based methods in predicting differential splicing events, splicing strength at highly regulated splice sites, and isoform usage. The model enables systematic identification of tissue-specific splicing quantitative trait loci and their functional impacts. Furthermore, HELIX predicts patient-specific splicing dysregulation with quantitative attribution to genetic variants and abnormal RNA-binding protein expression in colon cancer cohorts. Through transfer learning, the HELIX model can be adapted to single-cell RNA sequencing data, thereby enabling the prediction of cell-type-specific isoforms.",
"42171198": "ID: 42171198\nTitle: Targeting lipid nanoparticle mediated co-delivery of edaravone and kaempferol for amyotrophic lateral sclerosis therapy.\nAbstract: Amyotrophic lateral sclerosis (ALS) is characterized by a progressive and selective loss of motor neurons in the central nervous system, particularly in the brain and spinal cord. However, the main cellular mechanisms and cell death pathways leading to motor neuron degeneration have not yet been clarified. Research indicates evidence of ferroptosis in ALS, and the natural compound kaempferol has been demonstrated to inhibit neuronal ferroptosis. However, damage to the blood-brain barrier (BBB) prevents the drug from penetrating the central nervous system, which significantly reduces its therapeutic efficacy. Here, we developed a targeted delivery system named Eda/Kae@Lip-RGD (EKLR), which consisted of liposome-grafted RGD peptides for the co-delivery of the drugs kaempferol and edaravone, capable of crossing the BBB to provide co-delivery of kaempferol and edaravone for combined treatment of ALS. As expected, treatment with EKLR for one month significantly slowed down weight loss and improved athletic performance in SOD1G93A transgenic mice. Mechanistically, this nanomedicine suppressed ferroptosis by upregulating the antioxidant proteins GPX4 and SLC7A11, alongside the downregulation of Nrf2 and ACSL4 levels, thus collectively preserving neuronal integrity. Meanwhile, EKLR restored the normal morphology and the survival rate of neurons and maintained the mitochondrial structure and morphological integrity. Accordingly, this nanoplatform may represent a distinctive and potentially effective strategy for achieving neuroprotection in ALS as well as in other disorders of the central nervous system.",

Upon nuclear clearance and mislocalisation, TDP-43 enters the periphery; acetylation shapes its conformation, trafficking and immunogenicity. This narrative review synthesises single-cell transcriptomics, proteomic immunoprofiling and clinical inflammatory phenotyping to examine whether site-specific acetylated TDP-43 species may be associated with peripheral inflammatory signatures relevant to ALS immunopathology. By integrating separate datasets on acetylated TDP-43, monocyte phenotypes and cytokine modules, we propose two provisional endotypes characterised by monocyte reprogramming, cytokine modules and Blood-Brain Barrier (BBB) dysfunction-each representing clinically actionable pathways. Framed as a provisional neuroimmune interface, the acetylation state is considered here as a plausible molecular correlate and potential therapeutic entry point: a measurable clue to inform pharmacological targeting and, potentially, a modifiable target via p300CREB-Binding Protein (CBP)-Histone Deacetylase (HDAC) axes or sirtuin activity. Recasting TDP-43 from neuropathological hallmark to immunoactive sentinel supports a shift from descriptive nosology to stratified immunotherapy, in which treatment allocation is informed by acetylation-defined peripheral signatures.",

This study uses the TCGA public dataset to conduct differential analysis on lncRNAs in 39 diseased tissues and their normal counterparts from 413 colorectal cancer patient samples, identifying 458 differentially expressed lncRNAs (DELncRNAs). Univariate Cox regression analysis revealed 23 DELncRNAs significantly associated with overall survival (OS). These 23 DELncRNAs were further refined using the LASSO algorithm to determine their feature coefficients. An adaptive mining approach with dual-attention mechanisms was employed to explore the correlative properties between various factors and survival time. A bidirectional long short-term memory (BiLSTM) neural network was established for survival prediction. The model was validated using the Jiangnan University colorectal cancer dataset, demonstrating reliable predictions for patient survival and valuable support for clinical decision-making. The AUC values for patient survival prediction during the 3-year, 3-6 year, and 6-year periods were nearly 1.00, significantly outperforming other comparative trials.",

Although the co-occurrence of the 2 diseases has been widely observed, the underlying molecular mechanisms remain unclear. Herein, we evaluated the causal link between PBC and OP using Mendelian randomization (MR) and explored shared molecular mechanisms through bioinformatics and machine learning. We performed two-sample MR using genome-wide association study summary data for PBC and OP from the Integrative Epidemiology Unit database. Inverse-variance weighting was used as the primary MR method, with heterogeneity and horizontal pleiotropy tests performed to exclude potential biases. To explore shared molecular mechanisms, we analyzed transcriptomic datasets from the Gene Expression Omnibus database, identified comorbidity-associated differentially expressed genes, and applied multiple machine learning algorithms for biomarker screening and validation, combined with immune infiltration analysis. Our study showed that MR demonstrated that PBC significantly increases the risk of OP, while transcriptomic analysis identified 36 shared differentially expressed genes enriched in key biological pathways such as ribonucleic acid splicing and ubiquitin-mediated proteolysis. Furthermore, using 3 machine learning algorithms, we identified 12 PBC-specific and 4 OP-specific diagnostic genes, whose intersection revealed vacuolar protein sorting 37 homolog C (VPS37C) as a common diagnostic biomarker. In both diseases, VPS37C exhibited an area under the receiver operating characteristic curve value >0.7, demonstrating its robust predictive performance. In addition, VPS37C expression was found to be significantly correlated with the infiltration landscape of multiple immune cell types in both PBC and OP. This study identified VPS37C as a shared diagnostic gene linking PBC and OP, providing new insights into their comorbidity at both genetic and immune levels. Our findings further elucidate the molecular mechanisms underlying the comorbidity of PBC and OP, offer novel clues for understanding their pathogenesis, and highlight promising diagnostic and therapeutic targets for clinical application.",

In this study, we report that wild-type PDI, through its specific interaction with TDP-43, markedly attenuates phase separation of TDP-43, competitively displaces G3BP1 to disassemble TDP-43/G3BP1 condensates, and further counteracts the pathological mislocalization, abnormal phosphorylation, and pathological aggregation of TDP-43 through the b' domain of the enzyme. Ultimately, this alleviates mitochondrial damage and neuronal toxicity caused by TDP-43 aggregation and suppresses UNC13A cryptic splicing in stressed cells. In the presence of abnormal forms of PDI, however, PDI loses its activity, and stress granules containing TDP-43 are assembled into amyloid fibrils, resulting in mitochondrial impairment and neuronal cell death in ALS and AD-TDP patients. These findings not only provide new insights into the pathogenic mechanisms of TDP-43 in neurodegenerative diseases such as ALS and AD-TDP, but also propose PDI as a potential therapeutic target.",

Although classically defined as a brain-restricted disorder marked by striatal and cortical degeneration, increasing evidence suggests HD as a multisystem disease involving both central and peripheral pathological alterations. This review aims to provide an integrated overview of neuronal and non-neuronal mechanisms underlying HD, focusing on systemic alterations that influence disease onset, progression, and clinical variability. This review also aims to connect neuropharmacology with pharmaceutical formulation strategies, particularly emphasizing the therapeutic and drug-delivery challenges and nanotechnology-based solutions. A structured literature review was conducted using databases including PubMed, EMBASE, and Scopus. Using the appropriate keywords, original articles, clinical studies, systematic reviews, meta-analyses, and high-quality reviews were selected based on their relevance to HD pathophysiology and therapeutic strategies. HD manifests with motor, cognitive, and psychiatric disturbances; however, this review highlights that peripheral immune activation, gut microbiota dysbiosis, and multiorgan pathology are not merely secondary features but interact with neural circuits, contributing to disease heterogeneity and progression. Current therapeutic approaches are largely symptomatic, achieving minimal effectiveness in disease modification due to challenges such as poor blood-brain barrier penetration, limited target selectivity, and inter-individual variability. New strategies, such as nanotechnology-based drug delivery systems, biologics, and gene editing tools, offer advantages and support a deeper understanding of therapeutic limitations and disease mechanisms, yet their translational applicability remains constrained by limited clinical validation, safety concerns, and scalability problems. Reconceptualizing HD as a multisystem disorder provides a more comprehensive framework for therapeutic development. Integrating central and peripheral disease mechanisms with advances in targeted drug delivery and patient stratification approaches, such as sex differences, hormonal influences, and environmental factors, is essential for translational progress toward personalized therapeutic approaches. Future research should prioritize interdisciplinary approaches to bridge the gap between mechanistic discoveries and effective disease-modifying interventions.",
"42182497": "ID: 42182497\nTitle: WATER reveals heterochrony of molecular programs underlies developmental failure caused by minor spliceosome inhibition.\nAbstract: The final limb structure reflects coordinated deployment of molecular programs, defined not only by which genes are expressed but when they are activated and silenced across time. Existing omics analyses obscure the temporal unfolding of these programs and conflate program identity with deployment timing by assuming temporal equivalence between conditions. We developed WATER (Weighted Windowed Assignment of Temporal Expression of RNA), a framework that reconstructs temporal gene expression trajectories independently within each condition, enabling direct comparison of temporal program architecture between wild-type and perturbed systems. Applying WATER to U11-null mouse forelimb development revealed that minor spliceosome inhibition redistributes genes across inappropriate temporal trajectories. Minor spliceosome inhibition causes splicing defects in minor intron-containing genes such as the PRC2 component Eed, leading to reduced H3K27me3 deposition and chromatin-transcription divergence. Single-cell RNA sequencing revealed persistence of progenitor states, impaired chondrogenic progression, and p53-dependent apoptotic checkpoint activation. Orthogonal WATER analysis of Eed-knockout stem cells recapitulated key features of chromatin gating failure, including temporal redistribution of skeletal development programs and progenitor state persistence, confirming that Eed loss alone is sufficient to produce temporal program redistribution independently of other splicing defects. Trp53 ablation in U11-null limbs partially rescued distal limb structures without correcting the underlying splicing defects, establishing that checkpoint activation amplifies rather than initiates the timing disruption. The limb retains much of its molecular toolkit but executes it in the wrong order, demonstrating that developmental failure arises from mistimed deployment of intact molecular programs. Thus, temporal program architecture is a fundamental organizing principle of morphogenesis.",

CHCHD2 and CHCHD10 mutations caused neurodegeneration in model animals as seen in patients, but their pathophysiological roles remain elusive. Here we reported a direct role of CHCHD2 and CHCHD10 in autophagy. We identified a protein complex composing of CHCHD2-CHCHD10-C1QBP/p32-Atg8-family proteins (ATG8s), in which each molecule interacted with another. CHCHD2, CHCHD10 and C1QBP/p32 associated with ATG8s, preferentially, GABARAPs. Disease-associated CHCHD2 and CHCHD10 mutations exhibited varied interaction with ATG8s. By binding to GABARAPs, CHCHD2 and CHCHD10 underwent autophagic degradation, and recruited the ULK1 complex. Autophagy initiation defects occurred upon transient knockdown of CHCHD2, and also in human iPSC-derived CHCHD2-/- or CHCHD2T61I dopaminergic neurons. Importantly, CHCHD2 and CHCHD10 promoted autophagy. CHCHD2 reduced protein aggregates in cells and toxic SNCA/\u03b1-synuclein species in mouse striatum.

Mechanistically, pathological TDP-43 mislocalized to membrane lipid rafts (MLRs), resulting in decreased MLR-associated GluN2A expression and degenerative changes in neuronal ultrastructure. In contrast, SynCav1 delivery alleviated TDP-43 mislocalization on MLRs, stabilized MLR-associated GluN2A expression, and preserved synaptic ultrastructure. Furthermore, SynCav1 mitigated TDP-43-induced mitochondrial hyper-fragmentation and excessive mitochondrial fission signaling. These findings establish a novel link between TDP-43 proteinopathy and MLR instability, supporting SynCav1 as a \"neuron-centric\" candidate for treating TDP-43-related neurodegeneration.",

Quantitative MRI (qMRI) has emerged as a complementary tool that may detect progression earlier and more precisely. Integrating different data modalities is challenging with conventional approaches, and artificial intelligence (AI) can help overcome this. Our aim is to develop robust models capable of predicting clinical progression in LGMD-R2 by incorporating AI-based techniques into the analysis pipeline. Data from 188 COS 1 participants were analysed. Disease progression was assessed using the North Star Assessment for Limb Girdle type Muscular Dystrophies (NSAD). Ambulatory individuals with a maximum NSAD\u2009\u2265\u200920 were included, and progression trajectories were identified through hierarchical clustering. Feature selection was performed using a machine learning pipeline, and top predictors were entered into stepwise logistic regression to build clinical-only and combined clinical-MRI models. Two stages of progression were identified, a fast one with a mean three-year loss of 14.4 NSAD points, and a moderate one, with a mean loss of 3.8 NSAD points. The combined model achieved better balanced accuracy than the clinical-only one (83.7% vs 78.7%). Key predictors in the combined model were disease duration and fat content measures in the anterior thigh and gracilis muscle, while the clinical model included disease duration, creatine phosphokinase (CK), and 10 m walk/run test velocity. Progression in LGMD-R2 can be grouped into distinct clinical trajectories. Individuals at a faster stage of progression were younger, had shorter disease duration, higher CK, greater weakness, and relatively preserved vastus intermedius and gracilis muscles. AI enabled efficient integration of heterogeneous data, and qMRI biomarkers provided complementary information that improved predictive accuracy.",

Extracellular vesicles, particularly exosomes, that move bioactive substances between the stomach and the brain, such as proteins, lipids, metabolites, and microRNAs, may improve the gut-brain axis. In the past years, the role of exosome-mediated communication has been recognized as significant in relation to the etiology, continued progression, and potential treatment of neurodegenerative disorders. The authors of this review article present a summary of the current understanding of the relationship of gut microbiome, exosome biogenesis, and the pathophysiological development of neurodegenerative diseases. Evidence from laboratory studies, animal studies, and newly emerging human studies suggests that microbiome-based metabolites and inflammatory mediators may modulate how exosomes are produced, what they carry, and how they interact with the blood-brain barrier. These exosomal signals may impact neuroinflammation, neuronal signaling, and the spread of pathological proteins of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease. In addition, they examine some possible ways to target the gut-brain axis from a therapeutic perspective, including manipulating the gut microbiome, providing probiotics and/or prebiotics, performing fecal microbiota transplantation, and/or using engineered extracellular vesicles as vehicles for drug delivery. The authors also outline some of the methodological differences that make it difficult to assess the effects of exosomes.",

While most cases are sporadic, around 10% are familial. Recent genetic studies show that many apparently isolated cases carry pathogenic mutations, highlighting the importance of penetrance, the probability that a causal mutation manifests clinically. This review focuses on mutation penetrance in ALS (C9orf72, SOD1, TARDBP, FUS genes), its variability across genes, age, and environmental or genetic modifiers, and its implications for genetic counseling. Identification of pathogenic mutations informs the monitoring of relatives and, in some cases, gives access to targeted therapies or clinical trials. Counseling of asymptomatic relatives must consider incomplete penetrance, which can lead to delayed or absent disease manifestation. ALS exists on a clinical and genetic continuum including related disorders, such as frontotemporal dementia, further influencing risk interpretation. Advances in panel, whole-exome and whole-genome sequencing refine our understanding of penetrance and enable precise diagnostics, and potential tailored therapies. Understanding penetrance is therefore essential to translate mutation discovery into informed clinical decisions and genetic counseling in ALS.",

Its integration across the surgical pathway can improve clinical outcomes, efficiency, and patient safety. This narrative review provides an overview of the current and emerging applications of AI in SDM. A structured search of electronic databases was conducted using PubMed, Scopus, Web of Science, and Google Scholar. The search primarily focused on peer-reviewed publications from 2015 to 2025. AI applications include radiologic image analysis for preoperative planning, electronic health record mining for individualized surgical strategies, risk and immunological response prediction, and genomic analysis to guide treatment selection. Intraoperative, AI-based video, image, and physiological data processing can support real-time decision-making by improving precision, identifying anatomical targets, and predicting complications earlier. Postoperatively, AI systems can monitor patient data to detect complications, evaluate outcomes, and tailor follow-up therapy. Despite these advantages, challenges remain, including data quality and availability, model explainability, and others.

To decipher the underlying mechanisms responsible for these contradictions, we leverage emerging technologies that establish comprehensive cellular and spatiotemporal contexts for its signaling pathway. These approaches elucidate the mechanisms underlying central nervous system diseases and their potential therapeutic applications. In this review, we demonstrate how these advanced technologies enhance our understanding of the mechanism of activin A: CRISPR-based editing validates critical receptors such as ACVR1B in the process of remyelination; organoid and organ-on-a-chip systems model human-specific cellular interactions; spatial and single-cell multi-omics delineate expression and communication networks; and optogenetics/chemogenetics enable precise spatiotemporal control of signaling pathway activity. This technological toolkit provides a robust framework for elucidating the context-specific roles of activin A in conditions such as ischemic stroke, neurodegenerative diseases, glioma, epilepsy, and traumatic brain injury, encompassing key processes including neuroprotection, inflammation, and repair. Furthermore, these mechanistic insights inform next-generation interventions, including adeno-associated virus-mediated gene therapy for localized modulation and advanced nanodelivery systems for targeted biologic transport. Given these capabilities, artificial intelligence plays a crucial role in designing blood-brain barrier-permeable ligands and optimizing smart nanocarriers. By contrasting preclinical data with the clinical pipeline, which currently emphasizes peripheral diseases, we propose that integrating mechanism-decoding technologies with artificial intelligence-engineered delivery platforms is a critical pathway for advancement.",

The One Health resistome framework recognises that resistance genes circulate continuously across clinical, agricultural, and environmental compartments through horizontal gene transfer, co-selection mechanisms, and anthropogenic contamination. This comprehensive review synthesises current evidence on integrated AMR surveillance, examining how digital technologies are transforming our capacity to monitor, predict, and respond to resistance emergence. Key advances include whole-genome sequencing enabling high-resolution pathogen tracking, metagenomics revealing environmental resistome diversity, machine learning algorithms predicting resistance phenotypes with >\u202f85% accuracy, and point-of-care diagnostics extending sophisticated testing to resource-limited settings. Geographic information systems facilitate spatial hotspot identification, while wastewater-based surveillance provides early warning capabilities, detecting resistance genes before clinical manifestation. Despite technological progress, substantial challenges persist: fragmented data streams across sectors, lack of standardised environmental monitoring methods, limited laboratory capacity in low- and middle-income countries, and chronic underfunding. Emerging technologies, portable nanopore sequencing, CRISPR-based diagnostics, artificial intelligence, and blockchain-enabled data governance promise to address these gaps.

It is unknown whether the analysis of routine laboratory tests and vitals using artificial intelligence presents a scalable and portable system for capturing the spectral nature of common diseases. We constructed and validated machine learning models targeting seven common diseases-atrial fibrillation, breast cancer, coronary artery disease, migraine, rheumatoid arthritis, schizophrenia, and type 2 diabetes-using routine clinical measurements from 394,957 electronic health records (EHRs) in the BioMe Biobank and UK Biobank. The Resulting model outputs, termed spectral health index from machine measurements of electronic records (SHIMMER), were assessed for association with disease diagnosis, risk factors, biomarkers, onset, survival, complications, and medications in two cohorts. SHIMMER was associated with disease diagnosis, known risk factors, and biomarkers in expected directions in both cohorts. With greater SHIMMER, the prevalence of risk factors, complications, and medications continuously increased; for instance, age and hypertension, stroke risk and cardiac arrest, and beta blockers increased, respectively, with atrial fibrillation SHIMMER. Biomarker levels for type 2 diabetes, such as glucose, hemoglobin A1c, C-reactive protein, and triglycerides, changed stepwise as SHIMMER increased. Rising SHIMMER also revealed gradations of earlier disease onset and decreased survival, particularly for coronary artery disease and schizophrenia. A holistic, non-invasive marker derived from machine learning trained on routine clinical measurements snapshots multiple common diseases on a spectrum, quantifying disease risk, severity, onset, survival, sequela, and treatment.

However, a unified molecular classification scheme characterizing genomic alterations is lacking. Unsupervised and supervised clustering identified two distinct mutational signature subtypes. Kaplan-Meier analysis demonstrated that patients with the MUT2 subtype had a higher risk of death than those with the MUT1 subtype across multiple cohorts, including IMvigor210 (hazard ratio [HR], 1.74; 95% confidence interval [CI], 1.27-2.37; p < 0.001), UC-GENOME (HR, 1.54; 95% CI, 0.93-2.54; p = 0.091), The Cancer Genome Atlas (TCGA; HR, 1.45; 95% CI, 1.06-1.98; p = 0.020), MSK2022 (HR, 1.34; 95% CI, 1.10-1.64; p = 0.004), MSK2015 (HR, 3.43; 95% CI, 1.36-8.64; p = 0.005), and the Tongji cohort (HR, 4.99; 95% CI, 0.57-43.69; p = 0.11). Immunotherapy response rates were significantly higher in the MUT1 subtype than in the MUT2 subtype in IMvigor210 (31.8% vs. 13.1%; p = 0.003) and UC-GENOME (42.3% vs. 29.0%; p = 0.022). Consistent with these findings, single-cell analysis showed that MUT2 tumors were enriched in tumor-associated fibroblast subpopulations and had a lower abundance of immune effector cells.

Microbial biosensors exploit the specificity of living microorganisms, but signal variability, scalability limits, and interpretive challenges have constrained clinical adoption. Integration of machine learning (ML) and deep neural networks (DNNs) now enables adaptive, high-performance sensing systems. Applied to multi-sensor datasets-such as electrochemical impedance, Raman spectroscopy, and hyperspectral microscopy-convolutional neural networks (CNNs) and ensemble models achieve bacterial classification accuracies of 95-99%, while markedly reducing diagnostic turnaround times and enabling continuous surveillance.

We introduce TrASPr+BOS, a generative AI model with Bayesian Optimization for predicting and designing RNA for tissue-specific splicing outcomes. Transformer for Alternative Splicing Prediction (TrASPr) is a multi-transformer model that can handle different types of AS events and generalize to unseen cellular conditions. It then serves as an oracle, generating labeled data to train a Bayesian Optimization for Splicing (BOS) algorithm to design RNA for condition-specific splicing outcomes. We show TrASPr+BOS outperforms existing methods, enhancing tissue-specific AUPRC by up to 1.8-fold and capturing tissue-specific regulatory elements. We validate hundreds of predicted novel tissue-specific splicing variations and confirm new regulatory elements using dCas13. We envision TrASPr+BOS as a light yet accurate method researchers can probe or adopt for specific tasks.",

We conduct multi-ancestry transcriptome-wide association studies (TWAS) to discover potential breast cancer susceptibility genes. We develop ancestry-specific genetic models to predict levels of gene expression, alternative splicing, and 3' UTR alternative polyadenylation using genomic and transcriptomic data from 652 normal female tissue samples and apply these models to GWAS data of 178,534 cases and 248,300 controls for association analyses.

A major feature of TDP-43 pathology is its nuclear depletion, leading to the aberrant inclusion of cryptic exons during RNA splicing. STMN2 and UNC13A have emerged as prominent TDP-43 splicing targets, but the broader impact of TDP-43-dependent cryptic splicing on neuronal function remains unclear. Here, we report previously unidentified TDP-43 splicing targets critical for membrane excitability and synaptic function, including KALRN, RAP1GAP, SYT7, and KCNQ2. Using human stem cell-derived neurons, we showed that TDP-43 reduction induces cryptic splicing and down-regulation of these genes, resulting in impaired excitability and synaptic transmission. In postmortem brains from patients with FTD, these cryptic splicing events occurred selectively in neurons with TDP-43 pathology. Suppressing individual cryptic splicing events using antisense oligonucleotides partially restored neuronal function, and combined targeting almost fully rescued the synaptic deficit caused by TDP-43 loss. Together, our findings provide evidence that cryptic splicing in these synaptic and membrane excitability genes is not only a downstream marker but instead a direct driver of neuronal dysfunction, establishing a mechanistic link between TDP-43 pathology and neurodegeneration in ALS and FTD.",
"42235113": "ID: 42235113\nTitle: 3D craniofacial generative model for surgical planning in mandibular reconstruction.\nAbstract: Mandibular reconstruction following segmental resection for oral tumors is a complex procedure necessitating precise restoration of both masticatory function and facial aesthetics. Current Computer-Assisted Surgery (CAS) workflows remain fragmented, relying on subjective manual mirroring for shape completion and labor-intensive, non-standardized CAD operations for fibula osteotomy planning. Furthermore, existing deep learning approaches predominantly address mandibular shape completion in isolation, failing to integrate surgical feasibility or predict postoperative soft-tissue outcomes. In this paper, we propose a unified craniofacial generative framework that orchestrates mandibular completion, automated surgical planning, and postoperative facial prediction within a single pipeline. We employ a 3D latent diffusion model with patch-wise encoding strategy, pre-trained on a large-scale cohort of tumor-free subjects, to learn a robust anatomical shape prior. This prior is adapted via a specialized encoder to perform high-fidelity completion of defective mandibles. Subsequently, we introduce a geometric optimization algorithm based on dynamic programming to automatically generate fibula osteotomy and splicing plans that strictly adhere to the reconstructed mandibular contour. Finally, the framework predicts the postoperative facial morphology conditioned on the reconstructed bone, facilitating aesthetic outcome assessment. Validation on simulated and clinical datasets demonstrates that our framework achieves high anatomical fidelity in mandibular completion (Dice 85.61%, CD 1.43 mm) and precise postoperative facial prediction (Dice 97.67%, CD 1.57 mm). For surgical planning, the proposed algorithm improves reconstruction precision, achieving a volume ratio of 28.28%, a contour error of 2.24 mm, and a maximum projection of 3.55 mm compared with prior automated methods. Furthermore, the framework reduces the total planning time from over 34 min to under one minute, corresponding to a 60\u00d7 speedup, thereby supporting a practical and efficient paradigm for aesthetically aware surgical planning focused on the reconstructive phase.

"42239172": "ID: 42239172\nTitle: The retroelement-derived human protein PEG10 is a regulator of mRNA splicing in neurons.\nAbstract: Retroelements, including retrotransposons, endogenous retroviruses, and their fragments, as well as rare co-opted or domesticated retroelements, can contribute to neurodegenerative disorders and aging through modulation of gene expression and induction of neuroinflammation. Paternally Expressed Gene 10 (PEG10) is a retroelement-derived human gene that has recently been identified as a putative driver of Amyotrophic Lateral Sclerosis (ALS) and Angelman's Syndrome. PEG10 has been reported to bind nucleic acid and undergoes a complex self-processing pathway that results in gene expression changes when the protein accumulates in cells. Here, we report that PEG10 has selectivity for binding U/G-rich RNAs and influences widespread gene expression changes. PEG10 overexpression mimics the loss of TDP-43 in broad changes to gene expression, including dysregulation of mRNA splicing pathways. Specific changes to mRNA splicing were largely unique between TDP-43 knockdown and PEG10 overexpression, as classic TDP-43 targets including STMN2 were not altered by PEG10. Instead, we identified a unique role for PEG10 in regulating splicing of neuregulin 3 (NRG3), a ligand for the neuronal receptor ERBB4. In SH-SY5Y cells and in human neurons overexpressing PEG10, NRG3 protein levels were decreased along cellular processes, suggesting that these cells are less competent at signaling through the NRG3/ERBB4 axis. Using human patient data, we observed similar changes to NRG3 splicing in UBQLN2-mediated ALS, where PEG10 is accumulated, as well as in some cases of sporadic ALS. In conclusion, the retroelement-derived gene PEG10 plays an unexpected role in regulating splicing of neuronal transcripts, which mimics some of the transcript changes observed in human ALS patient samples. Ultimately, this work has implications for the study of PEG10, and mRNA splicing in neurological diseases associated with elevated PEG10 abundance.",
"42242212": "ID: 42242212\nTitle: Agility training enhances motor temporal precision by reweighting spinal phase-locked commissural inhibition.\nAbstract: Agile motor action requires rapid switching between motor states while maintaining stability. Because motor output combines fast and slow muscle fibers with distinct kinetics, prolonged slow-fiber activation can broaden burst envelopes and blur within-cycle transitions, limiting temporal precision. Here, we show that agility training improves locomotor timing by selectively compressing the activity of slow motor neurons through enhancing commissural inhibition. In adult zebrafish, training increased locomotor stability and reshaped cycle structure in vivo, shortening the contraction phase while extending relaxation. Ex vivo motor-nerve recordings revealed sharper burst envelopes and reduced temporal dispersion after training, explained by a selective narrowing of slow, but not fast, motor neuron discharge within each cycle. Training enhanced phase-locked commissural inhibition during locomotion, consistent with an inhibitory gate aligned to burst offset. Finally, electrophysiology and single-cell transcriptomics associated this plasticity with increased glycinergic receptor expression in slow motor neurons. Together, our findings identify a circuit and a molecular substrate for training-induced gains in agility and suggest that motor precision can be improved by inhibitory reformatting of slow motor output rather than by uniformly increasing excitation.",
"42242678": "ID: 42242678\nTitle: Pathogenicity prediction for noncanonical splice-altering variants based on multimodal feature fusion.\nAbstract: Splice-altering variants (SAVs) are the second most prevalent class of pathogenic genetic variants and are strongly associated with the occurrence and development of various diseases. However, current computational tools exhibit limited predictive capability beyond canonical GT-AG splice sites, making accurate assessment of noncanonical SAV pathogenicity a considerable challenge. To address this limitation, we developed MOSAIC (multimodal feature fusion for noncanonical splice-altering variants pathogenicity prediction), a deep learning framework designed for precise assessment of noncanonical SAV pathogenicity. MOSAIC integrates long-range contextual signals derived from a pretrained DNA language model, local sequence features captured from multi-scale convolutional neural networks, and functional annotations. By employing a transformer encoder and a gated fusion module, the model adaptively integrates these multimodal features. Benchmarking across multiple independent datasets demonstrated that MOSAIC consistently outperforms existing state-of-the-art methods, such as CADD and SpliceAI. It remains highly accurate and robust when evaluated on rare variants, gene-independent contexts, and the largest subset where all comparative methods yielded outputs. Furthermore, feature importance analysis revealed that long-range dependencies in DNA sequences and transformer-based integration were critical contributors to model performance. Interpretability analyses indicated that MOSAIC could identify key regulatory sequence motifs associated with transcription factors and RNA-binding proteins, offering mechanistic insight into how noncanonical SAVs disrupt splicing regulation and contribute to pathogenic processes. Overall, MOSAIC offers an accurate and interpretable framework for predicting the pathogenicity of noncanonical SAVs, thereby serving as a dependable computational tool for genetic diagnostics and precision medicine applications.

We analyzed clinical and genomic data from 97 NF patients using targeted panels, whole-exome sequencing (WES), and whole-genome sequencing (WGS) from June 2020 to October 2024. Variants were classified according to established guidelines, and their distribution across protein domains was evaluated using Bayesian multinomial logistic regression.

Sixty-nine variants were identified in NF1, NF2, and LZTR1, including 22 novel ones. In NF1, pathogenic deletions were enriched in non-domain regions, while substitutions predominated in domain regions, though without phenotype-specific associations. Two of three VUS were predicted and experimentally confirmed as pathogenic. One case achieved molecular diagnosis only through WGS after negative WES results. This study expands the mutational landscape of NF genes, underscores the diagnostic advantage of WGS, and demonstrates the effectiveness of advanced predictive and functional tools for VUS interpretation.",

To tackle this issue, we present CrisprFusion, a deep learning framework that explicitly encodes four biological features through a four-branch input structure. The core of our model is a novel Multi-Grain Cross Attention Fusion Module, which performs fusion at two levels: branch-level gating for adaptive reweighting of different modalities, and token-level alignment for capturing position-specific interactions along the 23-nt sgRNA sequence. We evaluate CrisprFusion on seven high-throughput datasets with six representative baselines. Our method achieves consistent and superior average performance across all datasets and remains competitive in cross-cell-line validation on four functional screens.

Recent epidemiological syntheses covering more than 30 countries now list over 1600 laboratory-confirmed human cases with a pooled case-fatality of about 12%, climbing beyond 18% in East Asia. The widely cited pooled case-fatality estimate derives from a PRISMA-guided systematic review and meta-analysis that searched PubMed, Scopus, Web of Science, ScienceDirect, and Google Scholar through December 2012 and pooled study-level event rates using inverse-variance methods with random-effects models when heterogeneity was present. We critically synthesize recent molecular, cellular, and translational studies to define how this swine commensal breaches host epithelial and blood-brain barriers (BBBs), subverts innate immunity, and disseminates systemically. Newly identified virulence mechanisms include serine-threonine kinase-driven claudin-5 cleavage, vimentin-dependent transcytosis, quorum-sensing control of biofilm maturation, and metabolic reprogramming that fuels neutrophil evasion. We integrate multiomics signatures with structural data to map conserved targets such as IdeSui and capsular polysaccharide that underpin next-generation conjugate and nanoparticle vaccines. Diagnostic advances spanning CRISPR-based assays and high-resolution imaging are assessed for their capacity to enable point-of-care detection. We also highlight host transcriptomic signatures that can be integrated into microfluidic chips, allowing syndromic discrimination between S. suis and pneumococcal meningitis within 40\u2009min, a critical window for targeted therapy. Finally, we present a prevention framework uniting farm biosecurity, rational antibiotic stewardship, probiotic and bacteriocin interventions, and community education.

Heterozygous mutations in TDP-43 cause familial ALS, known as ALS10. TDP-43 is predominantly localized in the nucleus under physiological conditions. Not only ALS patients with TARDBP mutations but also the majority of sporadic ALS patients exhibit TDP-43 pathology, which is defined by nuclear clearance and cytoplasmic aggregation. The inclusion of cryptic exons in genes such as STMN2 and UNC13A has emerged as a hallmark of TDP-43 loss of function, as demonstrated in TDP-43 knockdown models and postmortem analyses. However, it is not yet clear how TDP-43 levels and location change from healthy to pathological conditions in ALS. Motor neurons derived from induced pluripotent stem cells (iPSCs) have been widely used in ALS research and provide a promising platform to investigate early-stage disease mechanisms. However, challenges remain in generating models that faithfully recapitulate ALS pathogenesis. In this review, we summarize recent advances in TDP-43-related iPSC-derived motor neuron models and discuss future perspectives for elucidating ALS pathogenesis. We propose that longitudinal analyses of TDP-43 dynamics and co-culture systems will be essential to better model early ALS pathogenesis.",

Although regulatory annotation implicated multiple genes, PRRX1 showed broad expression across glaucoma-relevant ocular tissues and cell types, including trabecular meshwork and optic nerve head fibroblasts, pericytes, and astrocytes. In primary HTM cells, PRRX1 was significantly downregulated under combined CMS and TGF\u03b22 exposure. Zebrafish ortholog analyses support neuro-ocular relevance. Integration of GWAS, regulatory annotation, ocular transcriptomics, and functional modeling prioritizes PRRX1 as a plausible gene of interest warranting further investigation for potential involvement in POAG. Identification and integrative evaluation of this POAG-associated locus advances understanding of disease biology and may inform future risk stratification and therapeutic investigation.

Although immunotherapy and other therapeutic modalities has achieved significant therapeutic success in several malignancies, its efficacy in glioblastoma remains limited primarily due to the complex tumor microenvironment (TME) and physiological barriers such as the blood-brain barrier (BBB). In this context, nanomedicine and gene editing have emerged as promising strategies due to their unique ability to cross the BBB and protect therapeutic agents through intrinsic physicochemical properties. To overcome the physiological barriers for better therapeutic outcomes. Here, a novel aggregation-induced emission luminogen (AIEgen), NDA-DPE, was synthesized, exhibiting NIR-I to NIR-II fluorescence and dual photothermal (PTT) and photodynamic (PDT) properties through restricted intramolecular motion. Bone-derived neutrophil-based biomimetic nanoparticles (bNe@AIE/Cas9-CD73) were then prepared by integrating NDA-DPE with CRISPR/Cas9-mediated CD73 gene silencing. The neutrophil encapsulation enabled efficient BBB penetration and targeted accumulation in glioblastoma tissue. CRISPR/Cas9-CD73 downregulated CD73 expression, disrupted the ATP-adenosine axis, and reshped the immunosuppressive TME into an immuno-supportive one, increasing the therapeutic sensitivity of tumor cells. Under NIR-II excitation, bNe@AIE/Cas9-CD73 achieved fluorescence-guided PTT and PDT, inducing immunogenic cell death (ICD), stimulating immune-cell recruitment, and activating systemic antitumor immunity. bNe@AIE/Cas9-CD73 demonstrated a potent gene-photothermal-photodynamic-immune synergistic effect, significantly inhibiting glioblastoma growth and establishing a promising nanoplatform for effective and targeted glioblastoma treatment.",

Current pharmacological treatments primarily provide symptomatic relief and have a limited impact on disease progression. This article presents a narrative review of emerging gene therapy approaches aimed at modulating \u03b1-syn expression, aggregation, and clearance as potential disease-modifying strategies for PD. Gene-based interventions include viral vector-mediated gene delivery, antisense oligonucleotides, RNA interference, and gene-editing technologies. Preclinical studies and early-phase clinical trials suggest that these approaches may reduce \u03b1-syn burden, improve motor outcomes, and support dopaminergic neuron preservation. Adeno-associated viral and lentiviral vectors have demonstrated promise for targeted central nervous system delivery, although challenges related to dosage optimization, regional specificity, long-term safety, and immune responses remain. Complementary strategies focusing on enhancing molecular chaperone activity and activating autophagy-lysosomal pathways have also shown potential in facilitating \u03b1-syn clearance. Despite encouraging progress, several limitations hinder clinical translation, including off-target effects, immune activation, and the need to preserve physiological \u03b1-syn functions essential for neuronal homeostasis. Future success will depend on precise molecular targeting, optimized delivery platforms, and rigorous safety evaluation through well-designed clinical trials. This narrative review summarizes current advances, key limitations, and future directions in \u03b1-syn-targeted gene therapy, highlighting its potential role in advancing PD treatment beyond symptomatic management toward disease modification.",

Its ease of use and efficiency has accelerated advancements in genetic research and therapeutic development. However, unintended cleavage at off-target sites remains a significant concern, limiting the safety and broader applicability of CRISPR-based editing. Accurate computational prediction of off-target locations is therefore essential to mitigate potential risks and improve experimental design. In this study, we introduce CRISPR multi-branch transformer fusion (CRISPR-MBTF), a novel deep learning-based framework employing a multi-branch Transformer architecture combined with an attention-based fusion mechanism to model the intricate biological context influencing CRISPR activity. By capturing subtle sequence patterns and contextual dependencies, our model achieves enhanced predictive performance compared to existing approaches. Additionally, interpretability analyses uncover biologically meaningful patterns and highlight influential sequence regions, offering valuable insights into the determinants of CRISPR specificity.

However, the RNA therapeutic design space is extremely large, encompassing multiple variables, including codon identities, secondary structure, and design of specific regions. RNA therapeutic optimization is difficult due to the impracticality of exploring such a vast design space experimentally. To address this limitation, deep learning methods have been employed to optimize RNA therapeutic development. In this review, we examine the application of deep learning models across three key aspects of RNA therapeutic development (RNA structure prediction, CRISPR activity, and RNA delivery), highlighting major contributions in these fields and analyzing how deep learning model architectures could affect model performance. We then discuss challenges associated with using deep learning for RNA therapeutics, such as computational and data limitations. Finally, we offer perspectives on areas for future exploration, such as emerging model architectures and methods of integration with more advanced high-throughput screening techniques.

This review provides a unified framework to understand the interrelated molecular mechanisms driving these diseases, with a focus on identifying key disease-specific intervention nodes. Core contributors include oxidative stress, mitochondrial dysfunction, protein aggregation, neuroinflammation, and emerging roles of peroxisomal dysfunction in redox imbalance, lipid dysregulation, and inflammatory amplification. Single-target therapies often show limited efficacy due to the complex, interconnected nature of these pathways. In contrast, polypharmacology, which targets multiple disease-relevant mechanisms simultaneously, offers a more promising therapeutic strategy. This review critically examines how pathway crosstalk drives neurodegenerative progression, with particular emphasis on mitochondrial-ROS-inflammatory signaling, aggregation-proteostasis failure, synaptic-neuroimmune dysfunction, and gut-brain communication. It evaluates various multi-node intervention strategies, including multi-target-directed ligands (MTDLs), molecular hybrids, natural products, drug repurposing, and nanocarrier-based delivery systems. Advances in network pharmacology, artificial intelligence (AI), bioinformatics, and multi-omics have enhanced the identification of actionable therapeutic nodes, candidate compounds, and brain-targeted delivery platforms. Notably, the NOD-like receptor pyrin domain-containing protein 3 (NLRP3) inflammasome and cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathways-play distinct roles in neuroinflammation, amplifying neuronal damage by releasing inflammatory cytokines and inducing mitochondrial dysfunction. However, successful translation into clinical practice remains constrained by challenges such as blood-brain barrier penetration, patient heterogeneity, and biomarker limitations. The review advocates for a shift towards mechanism-informed, patient-stratified polypharmacological strategies to better address the network pathology of neurodegeneration, despite significant translational hurdles.",

Pathological TDP-43 aggregates have become a defining hallmark of neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and a large subset of frontotemporal lobar degeneration (FTLD). In the last decade, increasing evidence has challenged the initial thought of TDP-43 condensates as a purely pathological event, highlighting instead the physiological relevance of reversible self-association, polymerization and liquid-liquid phase separation (LLPS) in regulating TDP-43 functions. In this review, we provide an integrated overview of the structural determinants governing TDP-43 two-faced polymerization, with a particular focus on the prion-like domain and its parallelism with prion proteins. Indeed, while physiological assemblies support normal RNA processing, the dysregulation of LLPS by either disease-associated mutations, altered RNA-binding, aberrant post-translational modifications, or proteolytic cleavage can promote the transition toward irreversible, pathogenic aggregates. Finally, we summarize strategies aimed at eliminating TDP-43 aggregates or modulating its phase-separation behavior. Altogether, this review frames TDP-43 polymerization in both healthy and pathological conditions, offering a prion-like centered view of TDP-43 proteinopathies.",
"42309815": "ID: 42309815\nTitle: Stage- and Region-Dependent Proteomic Alterations in a Mouse Model of Creatine Transporter Deficiency.\nAbstract: SLC6A8 encodes the creatine transporter (CRT), which mediates creatine transport across the plasma membrane in the brain, including the blood-brain barrier and neurons. Creatine transporter deficiency (CTD), caused by pathogenic variants in SLC6A8, leads to cerebral creatine depletion and cognitive impairment. Here, we investigated the developmental molecular mechanisms underlying CTD using the pathogenic c.1681G>C (G561R) variant of Slc6a8, which corresponds to a variant identified in SLC6A8 in a patient with CTD. In vitro analyses using HEK293 cells expressing mutant mouse CRT carrying the G561R variant demonstrated impaired N-glycan maturation and plasma membrane localization of the transporter, resulting in markedly reduced creatine uptake, consistent with previous reports on the corresponding human CRT variant. To investigate the in vivo effects of this pathogenic variant, we generated CRT-G561R knock-in mice by introducing the c.1681G>C point mutation into the mouse Slc6a8 gene using the CRISPR/Cas9 system. These male mice exhibited severe reductions in brain creatine levels, postnatal growth retardation, and impaired spatial memory, despite preserved gross brain morphology. Quantitative proteomic analyses of the hippocampus and cerebral cortex during postnatal development revealed region-dependent protein alterations in CTD. The hippocampus showed pronounced early postnatal remodeling involving proteins related to actin cytoskeleton organization and vesicle-mediated membrane trafficking, whereas the cerebral cortex exhibited a more gradual response involving creatine biosynthesis-related enzymes and later-emerging mitochondrial pathways, including the mitochondrial translation machinery. These findings demonstrate stage- and region-dependent proteomic remodeling during postnatal brain development in CTD.Significance Statement Creatine transporter deficiency (CTD) causes cerebral creatine depletion and intellectual disability; however, the developmental mechanisms linking creatine loss to brain dysfunction remain unclear. We performed developmental proteomic profiling of the hippocampus and cerebral cortex using a mouse model carrying a pathogenic Slc6a8 variant identified in patients with CTD. Creatine transporter dysfunction induces distinct region- and stage-dependent molecular responses during postnatal brain maturation. The hippocampus shows early alterations in cytoskeleton-dependent membrane trafficking pathways, consistent with impaired synaptic and circuit maturation, whereas the cerebral cortex exhibits progressive metabolic and mitochondrial adaptations. These findings suggest that impaired creatine-dependent energy buffering disrupts distinct developmental programs across brain regions, potentially contributing to cognitive dysfunction by hindering early hippocampal circuit maturation.",

As biologically derived nanocarriers, exosomes have emerged as viable candidates for crossing physiological barriers and effectively delivering target molecules into the central nervous system. This review aims to summarize what is currently known about exosome biogenesis, cargo sorting, and immunological function in relation to infectious disease. In addition, it provides information on how different pathogens have taken advantage of exosomal pathways to increase their virulence and modulate the immune response, while also suggesting options for the therapeutic engineering of exosomes. It critically evaluates technological advances made in exosome engineering, such as CRISPR/Cas9-based cargo loading, ligand-directed surface modification of exosomes, targeted delivery of nucleic acids, and creation of stimuli-responsive release systems for exosome cargo for their potential application as precision therapies against pathogens that infect the brain.

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

Here, an adeno-associated virus encoding (G4C2)149 repeats was delivered via neonatal intrathecal injection, achieving widespread CNS expression with robust spinal cord targeting. This approach was applied to mice with graded loss of endogenous C9orf72 to interrogate both gain- and loss-of-function mechanisms. Longitudinal motor, behavioral, and pathological analyses revealed that repeat expression primarily drives mild, progressive muscle weakness, whereas coordination deficits were largely genotype dependent. Subtle gait abnormalities and hyperactivity were also observed. Within spinal motor regions, repeat-expressing mice exhibited dipeptide repeat protein accumulation, reduced NeuN-positive area, fewer motor neurons, glial activation, sparse phosphorylated TDP-43 pathology, and increased cryptic TDP-43 splicing. Cross-domain correlations further linked repeat expression, spinal pathology, and motor dysfunction. Collectively, these findings establish that CNS-wide repeat expression combined with reduced C9orf72 produces a coherent, mild ALS/FTD model.",

The blood-brain, blood-cerebrospinal fluid, and arachnoid barriers tightly regulate molecular traffic, restrict paracellular diffusion, and actively clear xenobiotics, limiting brain penetration and retention of large molecules and nucleic acid therapeutics. Additional barriers include heterogeneous and diffuse pathology, the need for precise anatomical targeting, vector dose-limiting toxicities, pre-existing and therapy-induced immunity to viral capsids, and procedural risks of neurosurgical or intrathecal administration. These constraints have slowed translation, reflected by the small number of approved central nervous system-directed gene therapies. Against this backdrop, a diverse therapeutic landscape has emerged. In vivo strategies are dominated by adeno-associated virus 9 (AAV9) and AAV2 vectors delivered intravenously, intrathecally (including intracisternal and intracerebroventricular routes), or via image-guided intraparenchymal and intraputaminal infusions, alongside intrathecal antisense oligonucleotides and RNA interference therapeutics. Concurrently, emerging approaches, including engineered AAV capsids, receptor- and transporter-mediated transcytosis, nanoparticle platforms, and focused ultrasound with microbubbles, have demonstrated compelling yet preclinical proof of concept. Future progress will likely depend on convergent advances in machine-learning-guided capsid, more controllable blood-brain barrier modulation, rational route selection tailored to disease topology, and optimized ex vivo and cell-mediated delivery strategies.

Deep learning (DL) models and genomic foundation models (GFMs) have achieved outstanding accuracy for predicting splicing variant effects in humans. However, their transferability to non-human species remains poorly understood, limiting applications in agricultural genomics, comparative biology, and non-model organism research, where experimentally validated variant datasets are limited or lacking. In this study, we comprehensively reviewed 35 computational approaches in terms of their architectural characteristics for splicing site and variant prediction and analysis. We systematically benchmarked the performance of 10 representative models for splicing variant prediction across human, rat, pig, and chicken, including four task-specific DL models and six GFMs, using our manually assembled benchmark datasets. Our benchmarking results revealed a substantial cross-species performance decrease (~21%-33% in the area under the receiver operating characteristic curve - AUROC) using task-specific models from human to non-human species datasets. We then applied a supervised adaptation to frozen GFM embeddings (DNABERT-2, Evo 2, Genos) by adding a lightweight classifier (i.e. a multi-layer perceptron) and reduced the cross-species performance decrease for rat and pig (8.56%-23.84% in AUROC), while performance on chicken was very close to human (decline within 1%, even exceeding by 0.52% when using the Evo 2 embedding).

Aberrant splicing caused by mutations can lead to severe diseases, including cancer and genetic disorders, underscoring the need for accurate computational tools to predict splice sites and detect disruptions. Existing methods have made significant advances in splice site prediction but are often limited in handling long-range dependencies due to high computational costs, a factor critical to splicing regulation. Moreover, many models lack interpretability, hindering efforts to elucidate the underlying biological mechanisms. Here, we present SpliceSelectNet (SSNet), a hierarchical Transformer-based deep learning model that predicts splice sites from DNA sequences spanning up to 100 kb. By integrating local and global attention mechanisms, SSNet efficiently captures both proximal and distal regulatory signals while maintaining single-nucleotide resolution. Across multiple benchmark datasets, SSNet achieves state-of-the-art performance in splice site prediction and aberrant splicing detection. Systematic in silico mutagenesis demonstrates that attention scores reflect functional sequence importance, supporting their biological relevance.

In phenomics, these models facilitate high-throughput extraction of crop phenotypic traits from multispectral, unmanned aerial vehicle, and ground-based imagery, supporting yield forecasting, disease diagnosis, and stress response monitoring. We critically evaluate the performance and limitations of each model type across tasks, considering trade-offs between complexity, accuracy, and interpretability, to offer practical guidance for crop researchers. Additionally, the review addresses major challenges in deploying deep learning-such as data scarcity, model transparency, and computational demands-and proposes future pathways to enhance model generalizability, multimodal data integration, and applications in intelligent breeding and sustainable agriculture.

In this review, we explore how different deep learning models help scientists tackle two big challenges: predicting gene behavior and extracting useful information from crop images captured by drones and cameras. These models can forecast traits like yield and disease resistance based on genetic data, while also enabling early detection of pests, diseases, and stress responses from field images. We also compare the strengths and weaknesses of various approaches to help researchers choose the right tool for their needs.

However, current reviews often catalog virus-disease associations without integrating this evidence into a unified conceptual model that also accounts for the therapeutic potential of viral platforms. This review investigates recent literature to propose a \"dual-role\" model for viruses in NDDs. We analyze how diverse viruses (e.g., HSV-1, HIV, EBV, and SARS-CoV-2) converge on shared pathogenic pathways, including protein misfolding, chronic neuroinflammation, and mitochondrial dysfunction, across different NDDs. Paradoxically, engineered viral vectors derived from neurotropic viruses are being investigated as tools for targeted gene therapy. To address these therapeutic applications of viruses, this review also provides an in-depth report of the various viral vector technologies developed. The approaches involved in designing rationally engineered viral vectors based on various adeno-associated virus serotypes through rational design, directed evolution and machine learning strategies, as well as the lentiviral and herpes simplex virus-based platform are described. Different strategies that have been used to incorporate large and/or small payloads such as gene replacement, RNA interference, microRNA cassettes, CRISPR-based gene editing (base editing, prime editing, CRISPRa and CRISPRi) and the double AAV systems to deliver larger transgene cassette have also been reviewed. This review further includes various routes of administration including intrathecal, intracerebroventricular and convection-enhanced delivery with the use of Focused Ultrasound. The constraints imposed by the Blood-Brain Barrier are discussed, especially the approach using receptor-mediated transcytosis for crossing. The review also critically evaluates obstacles toward clinical translation of viral vectors due to various factors including immunogenicity, the presence of pre-existing neutralising antibodies and dose-dependent toxicity, illustrated by the fatal outcome of ASPIRO and DMD trials. Finally, this review concludes with other promising non-viral approaches such as lipid nanoparticle and extracellular vesicles.

However, shortened TDP-43 (sTDP-43) splice isoforms where the PrLD is largely replaced by an 18-residue carboxyl-terminal tail also contribute to ALS pathophysiology and are enriched in motor neurons. Curiously, despite lacking most of the PrLD, sTDP-43 exhibits pronounced insolubility in cells and tissue of patients with ALS. Here, we establish that the short, isoform-specific carboxyl-terminal tail of sTDP-43 confers high aggregation propensity, which is encoded by two clusters of steric zippers, and can be mitigated by short RNA chaperones. Disrupting these zippers enhances sTDP-43 solubility at the pure protein level and in neurons. Notably, these steric zippers, rather than a predicted nuclear export signal in the carboxyl-terminal tail, drive cytoplasmic mislocalization and aggregation of sTDP-43 in neurons. Thus, we define the sequence-encoded determinants of aberrant sTDP-43 assembly and provide mechanistic insights into sTDP-43 disease pathology.",
"42343570": "ID: 42343570\nTitle: STMN2 protein depletion via translation deficits and stress granules in amyotrophic lateral sclerosis.\nAbstract: STMN2 is an abundant neurospecific protein dysregulated in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS). We previously reported that cellular stress can lead to STMN2 loss due to TDP-43 nuclear condensation. Here, using human and murine neuronal cell models, multiple pharmacological tools, in situ single-molecule analysis of translation and RNA localisation, and longitudinal analysis of neuronal fitness/survival, we establish TDP-43-independent mechanisms of STMN2 depletion under stress. We find that human STMN2 protein level is extremely labile under acute high-magnitude stress. Early in stress, STMN2 is suppressed via activated proteasomal degradation, phosphorylation and translation repression by stress granules, independently of TDP-43 loss of function in splicing. We further show that STMN2 protein level is highly sensitive to chronic translation deficits, such as those elicited by prolonged low-grade stress. We find that low pre-stress STMN2 sensitises neuronal cells to stress-induced apoptosis, whereas moderately increased STMN2 is protective under stress. Finally, we demonstrate that STMN2 mRNA is upregulated in non-TDP ALS (ALS-FUS) models, which may compensate for translation/stress granule defects in this disease subtype. Consistent with the compensation hypothesis, STMN2 mRNA is also upregulated in the relatively spared (cortex), but not severely affected (spinal cord), CNS regions in ALS-TDP. In conclusion, our study implicates two common denominators in neurodegeneration - dysregulation of translation and stress granules - in STMN2 depletion, independent of TDP-43 loss of function. It also describes an RNA-based compensatory mechanism in ALS underling the unique vulnerability of neurons with developing TDP-43 pathology.",

In real biological samples, however, analytical performance is rarely determined by signal enhancement alone. Biofluids such as serum, plasma, saliva, urine, and interstitial fluid contain complex biomolecular mixtures that interfere with target capture, spectral response, and data interpretation. A practical SERS biosensor must therefore localize targets, stabilize spectral responses, tolerate matrix-induced variation, and convert complex spectra into reliable analytical information. This review discusses recent progress in SERS biosensing from an integrated system perspective, with particular focus on artificial intelligence/machine learning (AI/ML)-assisted interpretation. Direct label-free SERS provides chemically transparent readouts but is limited by stochastic adsorption, hotspot heterogeneity, and spectral variation in complex samples. Bio-recognition interfaces improve target localization, while signal-transduction strategies based on nanotags, immunoassays, clustered regularly interspaced short palindromic repeats (CRISPR) systems, nanozymes, and lateral-flow formats decouple molecular recognition from spectral generation. Digital SERS further improves measurement robustness by converting fluctuating intensities into countable, event-based outputs. AI/ML-assisted analysis can support full-spectrum classification, calibration transfer, explainability, and patient-level decision-making. We frame AI/ML-assisted SERS biosensing as an integrated architecture connecting substrate design, interface engineering, signal transduction, digital measurement, and clinical validation. Future progress will depend as much on validation-ready workflows as on plasmonic enhancement itself, especially for systems intended to operate across different samples, instruments, and clinical settings.",
"42347120": "ID: 42347120\nTitle: RNA-Binding Proteins in Ageing and Age-Related Disease.\nAbstract: RNA-binding proteins (RBPs) are essential regulators of all aspects of RNA metabolism, including splicing, stability, localisation, translation, and degradation. Through their ability to recognise specific cis-elements in target transcripts, often via RNA-recognition motifs or other conserved domains, RBPs enable rapid cellular adaptation to stress and maintain proteostasis, particularly in post-mitotic tissues with limited transcriptional flexibility. Accumulating evidence positions RBPs as both modulators and drivers of the molecular hallmarks of ageing, including genomic instability, loss of proteostasis, mitochondrial dysfunction, cellular senescence, and chronic inflammation. This review synthesises peer-reviewed studies on the multifaceted roles of RNA-binding proteins in organismal ageing and age-related diseases. Key themes include the tissue- and age-dependent changes in expression of turnover and translation regulatory RBPs such as HuR (ELAVL1), AUF1 (HNRNPD), TIA-1, and tristetraprolin (ZFP36), which alter the stability of mRNAs encoding cell-cycle regulators, pro-inflammatory cytokines, and stress-response proteins. Systematic downregulation of core splicing factors, including PTBP1 and several heterogeneous nuclear ribonucleoproteins, drives widespread senescence-associated splicing alterations in pathways governing cell division, autophagy, DNA repair, and mitochondrial function, suggesting a causal contribution to the senescent phenotype. Prion-like RBPs such as TDP-43 and FUS exhibit age-dependent mislocalisation, nuclear depletion, and cytoplasmic aggregation, contributing to splicing defects, impaired RNA transport, and neurodegeneration in amyotrophic lateral sclerosis, frontotemporal dementia, and limbic-predominant age-related TDP-43 encephalopathy. Interactions between RBPs and non-coding RNAs, together with disrupted liquid-liquid phase separation dynamics, further exacerbate age-related decline. By integrating mechanistic studies from cellular and animal models with observations in human cohorts, this review underscores RBPs as central nodes linking multiple ageing hallmarks and highlights their potential as biomarkers and therapeutic targets to promote healthy ageing. Limitations of current models and priorities for future translational research are discussed.",
"42351313": "ID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.",
"42352457": "ID: 42352457\nTitle: Engineered Exosomes in Precision Neuro-Oncology: Mechanisms, Therapeutics, and Translational Challenges.\nAbstract: Exosomes are small vesicles released by cells that have attracted growing interest as drug delivery vehicles, particularly for brain diseases, where getting therapeutics across the BBB remains a fundamental problem. While conventional platforms such as liposomes, polymeric nanoparticles, and viral vectors often suffer from immune clearance and poor brain accumulation, engineered exosomes leverage natural cellular transport mechanisms to cross the BBB, protect cargo from degradation, and enable biocompatible interactions with target cells. This review takes a mechanistic and translational look at how exosomes are being engineered for CNS disorders, with a particular focus on glioblastoma. We cover exosome biogenesis through ESCRT-dependent and ESCRT-independent pathways, and how the competition between Rab27-driven secretion and Rab7-driven lysosomal degradation determines how many exosomes a cell releases, which has direct consequences for therapeutic production. We then discuss cargo loading strategies, from genetic approaches where donor cells are engineered to package specific molecules during biogenesis to physical methods like electroporation and sonication applied to isolated vesicles, alongside surface modification techniques for directing exosomes toward specific cell types. In glioblastoma, engineered exosomes have shown real promise for delivering chemotherapeutics across the BBB, targeting glioma stem cells, enabling CRISPR-based gene editing, and functioning as combined treatment and imaging tools. Applications in stroke and neurodegenerative diseases, where engineered exosomes carrying microRNAs and neuroprotective cargo have produced encouraging preclinical results, are also discussed. Scalable manufacturing and consistent targeting remain the hardest unsolved problems, and we outline emerging approaches including bioreactor-based production, programmable cargo loading, and patient-specific exosome design that are beginning to address these gaps. Overall, the progress reviewed here suggests that engineered exosomes are moving from an interesting biological concept toward a practically viable platform for CNS drug delivery.",

Pandemic-era Cas12a assays reached 95% positive predictive agreement against reverse transcription quantitative PCR (RT-qPCR) at 10 copies/\u03bcL, and deep neural networks now design Cas13 detection assays spanning 1933 vertebrate-infecting viruses, ranking candidate guides at Spearman correlations of 0.69 to 0.84 across internal and external validation. Generative deep-learning systems improve single-nucleotide discrimination two- to three-fold, computer vision classifies lateral flow outputs at 96.5% accuracy, and multi-biomarker fusion reaches an area under the receiver operating characteristic curve (AUC) of 0.998 in lung cancer detection. These results mask a narrow data foundation. Cas13a guide prediction still draws from a single screening library of 19,209 guide-target pairs, Cas12a has one published diagnostic model, and signal classifiers almost uniformly validate on single-site cohorts. This review synthesizes mechanistic constraints, predictive and generative models, and point-of-care classifiers, and maps the path beyond this data ceiling. Evolutionary pretraining on RNA corpora and lab-in-the-loop agents that convert model failure into targeted data acquisition define the route forward.",
"42357271": "ID: 42357271\nTitle: Folic Acid-Guided PLGA-Zein Core-Shell Nanoparticles for Co-Delivery of Temozolomide and Ellagic Acid to Overcome PARP-Mediated Chemoresistance in Glioblastoma.\nAbstract: Background: Glioblastoma (GBM) remains a lethal malignancy due to temozolomide (TMZ) resistance and limited drug penetration across the blood-brain barrier, largely driven by hyperactive DNA damage repair mechanisms such as poly (ADP-ribose) polymerase (PARP). To address these challenges, we developed folic acid-targeted PLGA-zein hybrid core-shell nanoparticles for the codelivery of the alkylating agent TMZ and the natural PARP inhibitor Ellagic acid (FA-TMZ/EA-PZ-CS NPs), thereby enabling simultaneous enhancement of drug delivery and suppression of chemoresistance pathways. Methods and Results: The dual-drug nanoplatform was fabricated using a double-emulsion solvent evaporation method and functionalized via EDC/NHS-mediated folic acid conjugation to promote receptor-mediated uptake. Physicochemical characterisation confirmed uniform spherical morphology, high colloidal stability, efficient drug encapsulation, and sustained biphasic drug release consistent with a core-shell diffusion mechanism. In LN229 glioblastoma cells, folic acid conjugation significantly enhanced cellular internalisation and cytotoxic efficacy compared to free drugs and non-targeted nanoparticles. Combination index analysis revealed strong synergism between TMZ and ellagic acid, resulting in markedly reduced IC50 values. Mechanistic studies demonstrated apoptosis induction, increased DNA damage, inhibition of cell migration at sub-cytotoxic concentrations, and downregulation of PARP gene expression. Conclusion: Overall, this study establishes a targeted core-shell nanotherapeutic strategy that integrates chemotherapy with DNA repair inhibition to overcome TMZ resistance, offering a mechanistically sound strategy that serves as a foundational framework for future translational research.",
"42357281": "ID: 42357281\nTitle: Tjap1/Pilt Is a cis-Golgi-Associated Protein Required for Golgi Integrity and Normal Drug Transporter Expression in Brain Microvascular Endothelial Cells In Vitro.\nAbstract: Background: Brain microvascular endothelial cells (BMECs) form the blood-brain barrier (BBB), a highly selective interface that restricts paracellular diffusion and regulates the transport of nutrients and drugs into the central nervous system via specialized transporters and receptors. Tight junction-associated protein 1 (Tjap1), also termed protein incorporated later into tight junctions (Pilt), has been localized to tight junctions (TJs) in epithelial cells and to the trans-Golgi network in fibroblasts; however, its expression, subcellular localization, and functional significance in BMECs are still unknown. Methods: We characterized Tjap1 subcellular localization in mouse and human BMEC cell lines as well as primary mouse BMECs by immunofluorescence with and without pharmacological Golgi disruption by treatment with Brefeldin A, Golgicide A or Pitstop 2. CRISPR/Cas9-mediated Tjap1 knockout cells were generated and examined with regard to their Golgi morphology using immunostaining. Tjap1 mRNA localization was examined by RNAscope in situ hybridization. Quantitative real-time PCR and Western blot was performed to assess the expression of BBB-associated efflux transporters, solute carrier transporters, and cellular receptors in control and Tjap1 knockout cells. Results: Tjap1 predominantly localized to the cis-Golgi compartment, co-localizing with Gm130 rather than Tgn38, and was absent from TJs in BMECs. Tjap1 knockout induced pronounced Golgi fragmentation BMECs. Importantly, Tjap1 knockout significantly downregulated mRNA-expression of Abcb1a, Abcb1b, Abcc4, Slc2a1, Slc7a1, Slc7a5 and Tfrc, while Abcg2 was upregulated. At the protein level, a decrease in the protein levels of Abcb1, Abcc4, Slc2a1, Slc7a1, and Tfrc was observed in Tjap1 knockout cEND cells. Conclusions: In BMECs, Tjap1 is a cis-Golgi-associated protein required for the structural integrity of the Golgi apparatus. Its deletion is associated with Golgi fragmentation and significant alterations in the mRNA and protein expression of drug transporters and receptors at the BBB. These findings identify Tjap1 as a candidate regulator of both Golgi architecture and the BBB transporter profile in vitro, with potential implications for modulating drug transport across the BBB.",
"42358359": "ID: 42358359\nTitle: Global research trends and hotspots of exosome-mediated drug delivery across the blood-brain barrier: a bibliometric study from 2015 to 2025.\nAbstract: The blood-brain barrier (BBB) is a major obstacle to targeted drug delivery for central nervous system (CNS) diseases. Although liposomes and polymeric nanoparticles have improved brain drug delivery, limitations remain in BBB targeting, long-term biocompatibility, and in vivo clearance. Exosomes are endogenous nanoscale extracellular vesicles with favourable biocompatibility, low immunogenicity, and BBB-crossing potential. Therefore, this bibliometric study summarises the current research status, future research trends, and challenges in the more specific field of exosome-mediated BBB drug delivery. A comprehensive search was conducted across the Web of Science Core Collection (WoSCC), PubMed, and Embase databases for relevant English-language literature on exosome-mediated drug delivery across the blood-brain barrier from 2015 to 2025. WoSCC served as the primary source for bibliometric analysis. PubMed and Embase databases were used for supplementary validation. Software such as VOSviewer, CiteSpace, and R-bibliometrix was employed for literature visualisation analysis. This study included 1,365 relevant articles from the WoSCC database, and the annual publication volume showed a steady upward trend. China and the United States significantly lead in both the number of publications and the number of core contributing institutions in this field. Co-occurrence analysis of keywords showed that research hotspots are mainly focused on exosomes, the blood-brain barrier, drug delivery, and Alzheimer's disease. PubMed and Embase were used as supplementary validation databases, including 1,089 and 1,517 records, respectively. Their annual publication trends, major countries/regions, core journals, and keywords/themes were generally consistent with WoSCC, supporting the macro-level stability of the bibliometric findings. Unlike previous bibliometric analyses that mainly focused on overall trends in CNS exosome research, this study focuses specifically on the direction of exosome-mediated drug delivery across the BBB. The findings show a shift from basic vesicle characterisation toward engineered delivery systems, CNS disease applications, and translational evaluation. Mammalian-derived exosomes remain dominant, while plant-derived vesicles, AI-assisted design, biomimetic hybrid nanovesicles, and gut-brain axis strategies are emerging areas of focus. Future research should prioritise systematic platform comparisons, standardised evaluation, quality control, scalable production, long-term safety, and regulatory pathways.",
"42358976": "ID: 42358976\nTitle: Identification of G4-regulated immune-related drug targets for prostate cancer based on G4 screen and machine learning.\nAbstract: G-quadruplex (G4) structures are important epigenetic regulators and potential therapeutic targets in cancer. However, their role in prostate cancer, particularly in relation to the immune microenvironment, remains poorly understood. We performed BG4 ChIP-seq to map genome-wide G4 structures in the prostate cancer cell line C4-2. Bioinformatics analyses integrated G4-associated genes with immune pathway enrichment and machine learning algorithms (LASSO, SVM-RFE, GBM, Na\u00efve Bayes, and GLM) to identify hub genes in prostate cancer progression. Clinical data from GTEx, TCGA, and HPA were analyzed for expression and survival. Functional validation included qPCR, CCK-8, colony formation, and wound-healing assays. Druggability was assessed using DrugnomeAI, and AI-assisted peptide design was performed with RFdiffusion and ProteinMPNN. We identified 1,289 prostate cancer-specific G4 structures, predominantly in promoter regions. Machine learning and immune enrichment analysis pinpointed IKBKB as a key hub gene in prostate cancer progression. IKBKB was overexpressed in prostate cancer tissues, correlated with advanced stage and poor prognosis, and was regulated by promoter G4 structures via transcription factors AR and ERG. IKBKB promoted genome instability, tumor stemness, and immune microenvironment remodeling. G4 stabilization increased IKBKB expression and activated the NF-\u03baB pathway, enhancing cancer cell viability, proliferation, and migration. Computational screening confirmed IKBKB's druggability and identified potential inhibitors (e.g., Auranofin). AI-assisted design generated peptide inhibitors targeting IKBKB and a CRISPR-dCas9 strategy for G4 disruption. IKBKB is a G4-regulated, immune-related driver of prostate cancer progression. Its overexpression is linked to NF-\u03baB activation, genomic instability, and immune microenvironment alterations. The study proposes two novel therapeutic strategies: G4 disruption at the IKBKB promoter and AI-designed peptide inhibitors. These findings provide a framework for combining epigenetic targeting with immunotherapy in prostate cancer.",

The FDA's accelerated approval of tofersen (Qalsody) in April 2023 marked the first treatment targeting a genetic cause of ALS. iPSC-derived drug candidates, including ropinirole and bosutinib, have completed early-phase clinical trials led by Japanese institutions. Cell therapies targeting neuroinflammation through regulatory T cells are being actively explored as immunomodulatory strategies, although efficacy remains to be established in adequately powered trials. Next-generation gene-silencing approaches-including RNA interference (RNAi) therapeutics and AAV-delivered microRNA-entered first-in-human trials in 2024-2025. The identification of STMN2 as a downstream target of TDP-43 dysfunction has opened a potential TDP-43-downstream nucleic acid therapeutic avenue for sporadic ALS, which constitutes approximately 90% of all cases, with company-reported interim data suggesting target engagement in the ongoing Phase 1/2 ANQUR trial (QRL-201).

In this formulation, KS-133 was encapsulated in the hydrophobic core of nanoparticles (NPs) coated with 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine-KS-487 (DPPE-KS-487), a conjugate of the cyclic peptide KS-487 and DPPE produced by a click reaction that binds low-density lipoprotein-related protein 1, enabling blood-brain barrier penetration upon subcutaneous injection. However, the click reaction generated multiple positional isomers and manufacturing required repetitive cycles of ultrasonication at high and low temperatures, posing challenges for industrial scalability. In the current study, we coated KS-133-containing NPs with 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-KS-487 (DSPE-KS-487), a novel conjugate of KS-487 with DSPE produced through a non-click method, thus eliminating positional isomers, and also established a simplified manufacturing process allowing a unidirectional transition from ultrasonication at high to low temperatures. This formulation remained physically and chemically stable for at least 12 months under refrigeration, with no changes in particle size, zeta potential, KS-133 content, or KS-487 presentation level. The formulation also exhibited brain penetration and therapeutic efficacy against VIPR2 agonist-induced novel object recognition impairment in mice comparable to those of DPPE-KS-487 NPs. Furthermore, no systemic side effects of hematologic, brain, heart, liver, and lung toxicity were detected following daily injections to mice for two weeks at five times the effective dose. This new KS-133 formulation incorporating DSPE-KS-487 as a brain-penetrant shuttle is a promising drug candidate for the treatment of cognitive dysfunction in schizophrenia.",

Rare neurological disorders, in particular, pose formidable challenges owing to their progressive nature and the difficulty of delivering thera-peutics across the blood-brain barrier. This review explores the emerging role of nanomedicine in transforming rare disease management through precision-targeted drug delivery, enhanced bioavail-ability, and the ability to bypass biological barriers. Nanoparticles (NPs)-including PEGylated NPs, lipid-based NPs, polymeric NPs, and hybrid formulations-are being engineered to deliver therapeu-tic agents for gene therapy, enzyme replacement, and RNA interference. These platforms have shown promise in treating conditions such as Krabbe disease, Niemann-Pick type C1, spinocerebel-lar ataxia type 1, and prion diseases. Additionally, nanotherapeutics are being investigated for pulmonary and congenital lung disorders, including cystic fibrosis and idiopathic pulmonary fibro-sis, with improved tissue penetration and reduced systemic toxicity. The review also highlights the potential of AI-integrated diagnostics and personalized nanomedicine to address disease heterogene-ity and improve patient outcomes. Despite these advances, significant barriers remain, including regulatory complexity, high development costs, and limited clinical models. The manuscript calls for collaborative innovation across academia, industry, and regulatory bodies to accelerate clinical translation and ensure equitable access.

"42369375": "ID: 42369375\nTitle: Mechanistic insights into the synaptic damage-repair and regeneration processes in neurodegenerative Alzheimer's disease: phytochemicals as neuroprotective agents.\nAbstract: Synaptic failure is one of the earliest and most significant contributors to the cognitive decline in Alzheimer's disease (AD), preceding extensive neuronal loss. Although amyloid beta (A\u03b2) plaques and neurofibrillary tangles (NFTs) of tau protein characterize the disease, memory impairment primarily results from the gradual deterioration of synaptic communications. This decline is caused by a complex interaction among mitochondrial energy deficits, cytoskeletal instability, disrupted exosomal signaling, and immune-mediated synaptic pruning. Mitochondrial dysfunction, particularly affecting complexes I and IV, leads to reduced ATP production, faulty mitophagy and disrupted calcium (Ca2+) homeostasis, placing the synapse under constant metabolic stress. Elevated reactive oxygen species (ROS) further activate stress pathways, including p38 MAPK and JNK, contributing to synaptic protein damage and impaired long-term potentiation (LTP). Furthermore, tau hyperphosphorylation destabilizes the neuronal cytoskeleton, weakening dendritic spine integrity and synaptic connectivity. At the same time, A\u03b2 alters the cargo carried by exosomes, facilitating the spread of pathogenic A\u03b2 and tau species between the neurons and modulating microglial activation and complement-mediated synaptic pruning. Additionally, emerging studies highlight the role of NETosis in exacerbating neuroinflammation and compromising the blood-brain barrier (BBB) integrity, thereby increasing synaptic damage. In contrast, phytochemicals such as resveratrol, ginkgolide B, curcumin, ferulic acid, epigallocatechin gallate (EGCG), and quercetin exert neuroprotection by restoring redox balance, altering exosomal communications, stabilizing cytoskeletal signaling, and reducing neuroinflammation. Moreover, delivery techniques such as nanoparticles and engineered exosomes enhance BBB permeability and enable targeted synaptic intervention. Overall, this review summarizes current mechanistic findings and highlights the potential of phytochemicals as multitarget therapeutic agents for synaptic repair and functional recovery in AD.",

Ginsenoside Rg3, a bioactive component of ginseng, has demonstrated neuroprotective potential, but its efficacy is constrained by poor BBB permeability. Here, we evaluated focused ultrasound (FUS)-mediated BBB opening (FUS BBBO) to enhance delivery of Rg3-loaded nanoparticles in a rotenone-induced mouse model of PD. Localized FUS sonications were applied to induce transient BBB disruption, followed by intraperitoneal administration of FITC-labeled Rg3 nanoparticles. In vivo and Ex vivo fluorescence imaging confirmed a significant increase in brain accumulation of nanoparticles after FUS BBBO. While Rg3 nanoparticle treatment alone showed moderate increases in ATP levels and Complex I activity, FUS alone produced comparable trends with slightly higher recovery. The combination treatment with FUS-mediated BBBO demonstrated higher mean values (ATP: 0.27\u00a0\u00b1\u00a00.06; Complex I: 1.98\u00a0\u00b1\u00a00.41) compared to the PD group, along with improvements in motor performance. These findings suggest that FUS-BBBO may enhance the delivery of Rg3 nanoparticles to the brain and support mitochondrial function. Overall, the combination approach showed a trend toward improved outcomes; however, further studies are required to confirm these effects and establish therapeutic potential for solid statistical analysis.",

In recent years, great progress has been achieved in the molecular design and the development of magnetic resonance imaging (MRI) probes targeting A\u03b2 species. They provide powerful tools for the early diagnosis and pathological investigation of AD. Here, we systematically review the molecular design strategies and recent advances in A\u03b2-targeted MRI probes. First, we introduce the molecular pathological basis of A\u03b2 aggregation and the importance of A\u03b2 as an imaging target. Second, we detail the core components of probe design, including the selection of targeting ligands (e.g., peptide mimetics, small molecules, and antibody fragments), optimization of signal units (e.g., Gd(III), Mn(II), superparamagnetic iron oxide nanoparticles (SPIONs), and \u00b9\u2079F), and the delivery strategies to enhance blood-brain barrier (BBB) penetration. We focus on how the probes achieve the transition from high-affinity binding in vitro to high-contrast imaging in vivo by means of changes in proton relaxation times (T1/T2) or the chemical exchange saturation transfer (CEST) effect upon binding to A\u03b2. Furthermore, the imaging performance of various probes (small molecule probes, nanoprobes, and smart responsive probes) in transgenic AD models is compared and evaluated, and the challenges related to sensitivity, specificity, and biosafety are discussed. Finally, we discuss future directions for A\u03b2-targeted MRI probes, including oligomer-specific probes, multimodal imaging probes, and theranostic platforms that include both diagnostic and therapeutic functions.

Widespread usage of new technology that impacts the therapeutic process has outpaced an analysis of how that technology might affect the meaning and effectiveness of that process. Lawsuits assume such technology causes harm, while limited data and the literature has been more mixed. From Frankenstein to CRISPR, new technology always has its cheerleaders and its detractors. The more the technology seems to impact a topic especially connected to our humanity, the deeper the convictions will be on both sides. Certainly, when it comes to psychotherapy, the introduction of new technologies such as telepsychiatry to Therabots has provoked discussion. We argue that while new technologies offer practical advantages, they risk functioning as structural defenses against the vulnerability and authentic intimacy essential to transformative psychotherapy. Through analysis of the therapeutic alliance, relational dynamics, and the psychology of vulnerability, this paper contends that the structural form of telepsychiatry does not alter the inherent nature of the therapeutic experience, whereas AI-mediated therapy may collude with maladaptive defenses, fundamentally altering the nature of the therapeutic encounter.",

Single-cell atlases reveal that in addition to gene expression changes, neuron types undergo shifts in subtype composition as they mature from nascent to mature identities. Shifts in subtype composition likely reflect the unique sequence of developmental events followed by each neuron and explain why, in some neuron types, functional diversity in adults is not fully explained by adult transcriptomics alone. Instead, adult neuronal identity is best understood as a culmination of transient and stable transcriptomic changes over time that are regulated by the combinatorial action of sequentially activated intrinsic and extrinsic factors. Which factors regulate transcriptional transitions in each neuron type, how trajectories are coordinated across functionally related neurons, how chromatin states accommodate temporal changes, and whether time itself is an important factor in determining adult identity, remain open questions.",

Nanomaterial-based drug delivery systems offer an opportunity to overcome the short half-life, low bioavailability, and poor BBB penetration that restrict conventional GBM therapeutics. Nanotechnology also provides safe, effective, and targeted drug delivery systems that enhance penetration, stability, and therapeutic efficacy.

Hampered by a multitude of constraints, including the complexity of secondary injury pathophysiological mechanisms, the selective permeability of the blood-brain barrier (BBB), and the side effects of therapeutic agents, systemic monotherapy has demonstrated limited efficacy in improving the long-term prognosis of TBI patients. Therefore, there is an urgent need to develop novel therapeutic strategies that can bypass the BBB, avoid systemic complications, and target multiple secondary injury mechanisms simultaneously. An injectable dual-drug-loaded nanohydrogel system was synthesized and its characteristics were evaluated. A mouse controlled cortical impact (CCI) model was established, and the nanohydrogel was locally administered intraoperatively. The neurological prognosis of mice was observed in both acute and chronic phases. Multiple methods, including evans blue assay, magnetic resonance imaging, transmission electron microscopy, western blot, enzyme-linked immunosorbent assay, and immunofluorescence staining, were used to evaluate the cerebral edema, BBB integrity, neuroinflammation, neuronal death/survival, angiogenesis, and neurogenesis after TBI. The nanohydrogel hybridizes hemoglobin (Hb) nanoparticles (NPs) with brain-derived neurotrophic factor (BDNF), uses these as the core to synthesize polydopamine (PDA) NPs, and loads dexamethasone (DEX) on their surface. In vitro drug release experiments confirmed that BDNF@Hb-PDA@DEX@gel had a high drug-loading rate and sequential sustained-release characteristics. The hydrogel matrix exhibited hemostatic and antibacterial effects. Both in vitro and in vivo experiments showed that the nanohydrogel could effectively reduce the acute-phase inflammatory response, protect BBB integrity, and alleviate cerebral edema by releasing DEX. In the late stage, it could promote brain tissue repair by releasing BDNF, including angiogenesis, neurogenesis, and neuron survival. The therapeutic efficacy of this dual-drug sequential delivery system was significantly superior to that of DEX monotherapy, and it could improve both acute and chronic neurological functions. By virtue of local sequential and sustained release of multiple drugs, the injectable nanohydrogel-based dual-drug delivery system can target multiple secondary injury mechanisms of TBI and exert spatiotemporal therapeutic effects, which provides a new strategy for the effective management of complex secondary brain injury and the improvement of long-term prognosis in TBI.",

These barriers hinder effective drug delivery, limiting therapeutic efficacy. This review provides a comprehensive analysis of the anatomical and molecular characteristics of these barriers, with particular emphasis on the heterogeneity of the BBTB and its implications for targeted drug transport. A detailed overview of various brain tumor types-including glioblastoma, pediatric brain tumors, and brain metastases-is presented alongside a critical evaluation of existing therapeutic modalities. The review highlights the advancement of ultramolecular pharmaceuticals specifically engineered to circumvent the BBTB, focusing on both transvascular and cell-mediated delivery mechanisms. The role of nanomedicine in modulating the immune response and altering the tumor microenvironment is explored as a promising avenue for enhancing therapeutic outcomes. Particular emphasis is placed on nanogels as a versatile and efficient drug delivery platform. Key fabrication techniques such as precipitation polymerization, emulsion polymerization, self-assembly, and micro-templating methods are thoroughly discussed, alongside strategies for polymer crosslinking to enhance stability and functionality. In addition, the review addresses preclinical evaluation strategies, including in vitro models (e.g., BBB-mimicking systems, tumor spheroids) and in vivo studies in animal models, to assess the safety, biodistribution, and therapeutic efficacy of nanogel-based systems. Finally, current clinical progress, challenges, and future perspectives are presented, underscoring the urgent need for innovative, targeted, and personalized drug delivery approaches. This review aims to guide future research in overcoming delivery obstacles and improving outcomes for patients with brain tumors through the strategic integration of advanced nanotechnology and molecular targeting.",

Despite advances in disease-modifying therapies (DMTs), current treatments primarily mitigate relapses and slow disease progression but fall short in comprehensively addressing cumulative disability or neurodegeneration. Berberine (BBR), a naturally occurring isoquinoline alkaloid, has emerged as a promising therapeutic candidate due to its potent immunomodulatory, anti-inflammatory, and neuroprotective properties. In this narrative review, we synthesize the molecular mechanisms underpinning BBR's effects on MS pathology and evaluate preclinical evidence from MS-relevant animal models. Studies in experimental autoimmune encephalomyelitis (EAE) -the primary MS model-and the cuprizone (CPZ) -induced demyelination model demonstrate that BBR (typically 5-300\u202fmg/kg in preclinical protocols) reduces pro-inflammatory cytokines, modulates immune responses, and promotes remyelination-processes critical for counteracting MS-associated neurodegeneration. BBR modulates key signaling pathways, including JAK/STAT and SPHK1/S1P, which are pivotal in attenuating immune-mediated damage and preserving blood-brain barrier (BBB) integrity. Despite its therapeutic potential, challenges such as poor bioavailability and suboptimal pharmacokinetics have spurred investigations into advanced delivery systems. Nanoformulations, particularly BBR-loaded iron oxide nanoparticles (BBR-IONP), have shown superior efficacy in preclinical models by enhancing CNS delivery and improving remyelination outcomes. By highlighting BBR's multifaceted bioactivities, this review underscores its promise as a complementary or alternative approach to address unmet needs in MS management, while acknowledging the critical need for clinical trials to validate these preclinical findings.",

Here we show that Nurr1 haplo-insufficiency results in a lethal coupled disorder across the liver-gut axis. Using a CRISPR-Cas9 generated murine model, we find that metabolically-activated heterozygous deficiency of Nurr1 results in profound hepatocellular necrosis and marked hepatic activation of inflammatory and pro-fibrotic genes coupled with dysregulation of the intestinal barrier, and severe small-intestinal dysbiosis. Multi-omics integration reveals a highly penetrant transcriptional signature of this herein termed liver-gut disorder, achieving up to 0.950 accuracy (SVM-RBF, 10-fold cross-validation) in classifying genotypes from integrated multi-omics features. Notably, we also demonstrate that these gene level perturbations in Nurr1 haplo-insufficiency can be thought of as learnable tissue 'morphologies' detectable by AI. Next, we created deep convolutional neural networks that accurately classify genotype from routine histopathology. Our algorithm achieves 99.50% accuracy in classifying hepatic fibrosis (Sirius Red), 99.20% in liver inflammation (H&E) and 92.31% in intestine (H&E). We provide the first multi-omics phenotype of Nurr1 deficiency, revealing its pivotal regulatory role in coordinating liver-gut homeostasis, and establishing a histopathological AI-driven framework. Grad-CAM saliency analysis confirms biological interpretability. Translational relevance is supported by human transcriptomic data (E-GEOD-61260) showing concordant upregulation of COL1A1 (log2FC= + 0.725, p <\u00a00.01), TGFB1 (+ 0.429, p <\u00a00.05), and MMP9 (+ 0.969, p\u00a0<\u00a00.01) alongside reduced NR4A2/NURR1 in human liver disease.",

The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS.",
"42384931": "ID: 42384931\nTitle: Real-time Targeted Enrichment in Single-cell Long-read Sequencing.\nAbstract: The vast majority of multi-exonic genes are alternatively spliced, generating diverse and cell-type-specific isoforms exhibiting functional differences. To better capture this heterogeneity using single-cell long-read sequencing data, we previously developed an exome-probe-based approach to enrich for exonic reads of target genes. While effective, this procedure is time-consuming and expensive. Real-time targeting offers a more cost-efficient solution for selectively sequencing reads of interest. Here, we performed real-time enrichment of exonic sequences of single-cell long reads by targeting spliced transcripts from 3377 genes implicated in brain functions and related diseases. Our approach increased the total number of spliced on-target reads to up to 1.82 times the control level. Notably, targeting lowly expressed subsets yielded spliced on-target reads 1.39 to 1.89 times the control. While these gains do not rival those achieved using chemical probe-based enrichment, they are sufficient to significantly enhance the power of downstream statistical analyses, such as testing for cell-type-specific isoform abundance. Specifically, compared to na\u00efve single-cell long-read sequencing, our approach yielded 2.42 times as many genes with significant differences in isoform usage between neurons and glia. Real-time targeting confirms cell-type-specific splicing in two early Mapt exons and newly reveals such events in\u2009>\u2009100 genes, including Bak1 and Atp8a1. Overall, our findings highlight real-time targeting as a versatile method for enhancing resolution in detecting differential isoform usage across cell types in single-cell long-read data, offering the potential to obtain a fuller view of cellular isoform diversity.",

While TIA is classically considered benign, recent studies reveal subtle yet potentially deleterious neuronal and glial changes. Ischemic stroke typically results in sustained hypoperfusion, infarction, blood-brain barrier (BBB) disruption, and robust neuroinflammatory cascades. IR injury, though potentially beneficial through vessel recanalization, paradoxically induces oxidative stress, cytokine release, and secondary infarction. This review systematically compares the molecular, histological, and behavioral profiles of these three conditions. Key differences include patterns of neuronal death, glial activation, oxidative damage, and BBB integrity. Human neuroimaging data and animal model histology are integrated to illustrate characteristic features across the spectrum. We also discuss current experimental models and their translational relevance, highlighting challenges in modeling comorbidities and chronic outcomes. Precision medicine strategies considering sex, age, and immune background-are emphasized as essential for advancing diagnostics and optimizing therapeutic efficacy. Emerging multimodal therapies, including pharmacological agents, stem cells, gene editing, and nanomedicine, hold promise but require rigorous validation. A deeper mechanistic understanding of each condition will be crucial for tailoring treatment strategies and bridging the translational gap in ischemic cerebrovascular disease.",

Single-cell whole-genome sequencing of 469 neurons from C9ORF72 ALS, C9ORF72 FTD, AD, and control brains revealed increased somatic single-nucleotide variants (sSNVs) and insertions/deletions (sIndels) in all three diseases. Mutational signature analysis identified a disease-associated sSNV signature consistent with oxidative damage and an sIndel process affecting 22% of ALS, 76% of FTD, and 61% of AD neurons-but only 2% of control neurons-resembling signature ID4, previously linked to topoisomerase 1 (TOP1)-mediated mutagenesis. Rapid approach to DNA adduct recovery (RADAR) assays confirmed increased TOP1-DNA covalent complexes, and duplex sequencing confirmed the increased sIndels and identified single-strand events as likely precursor lesions. TOP1-associated sIndel mutagenesis and genome instability thus represent a mechanism shared by both TDP-43 and tau neurodegeneration.",

Ultrasound irradiation applied in combination with gas-filled bubbles can induce cavitation and transiently increase the permeability of cellular membranes, thereby enhancing the intracellular delivery of therapeutic molecules. Our research group has developed ultrasound-responsive gas-containing lipid nanoparticles, initially termed bubble liposomes (BLs) and later referred to as nanobubbles (NBs), as carriers for nucleic acid delivery. Early studies indicated that BLs facilitated the efficient cytoplasmic delivery of small interfering RNA under ultrasound irradiation. Subsequent investigations expanded the platform to include diverse nucleic acids, including plasmid DNA and microRNA, and revealed therapeutic efficacy in disease models such as hindlimb ischemia. Further developments include strategies for brain-targeted gene delivery mediated via blood-brain barrier modulation and the design of stable anionic NBs with the capacity to load nucleic acids via cationic intermediates. More recently, polysaccharide-coated NBs and microfluidic preparatory methods have been assessed with a view to improving delivery performance and particle uniformity. These advances highlight the potential utility of nucleic acid-loaded NBs as theranostic platforms for the integration of ultrasound imaging and gene delivery. The continued development of this technology may contribute to the advancement of next-generation ultrasound-mediated DDS.",

However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models.",

In genome sequencing, machine learning variant callers greatly improve the accuracy and the rate at which single nucleotide and structural variants are called. In bulk RNA-Seq, AI augmented quantification, denoising, and differential expression modules complement the highly established STAR-featureCounts-DESeq2 pipeline, revealing subtle signals in big data sets. In single cell transcriptomics, deep learning approaches enhance batch correction, automate cell type annotation, and track developmental trajectories, hence clarifying cellular heterogeneity. AI-assisted guide RNA design, outcome prediction, and nuclease engineering enable more efficient CRISPR-Cas9 editing, reducing experimental cycles, and off-target effects. Finally, integrated platforms that combine genomic, transcriptomic, epigenomic, proteomic, and metabolomic layers provide an integrative view of cellular regulation and disease mechanisms.

Intrathecal administration provides a clinically validated route to bypass this barrier, yet the design principles for biodegradable lipid nanoparticles (LNPs) optimized for central nervous system (CNS) delivery remain poorly defined. Here, we synthesized a 200-member combinatorial library of structurally diverse, biodegradable ionizable lipids using the Passerini three-component reaction. High-throughput in vivo screening identified P3B, a lead lipid incorporating degradable linkages and optimized ionizable head groups, which enables potent and well-tolerated intrathecal mRNA delivery. In Ai9 reporter mice, P3B-LNPs encapsulating Cas9 mRNA/sgRNA induced robust and widespread tdTomato expression in neurons and astrocytes across multiple brain regions, achieving substantially higher editing efficiency than the clinical benchmark DLin-MC3-DMA (MC3). In LumA reporter mice, P3B-LNPs mediated efficient adenine base editing, restoring luciferase expression throughout the brain with 14.8% on-target correction and minimal off-target activity. Compared with MC3, P3B-LNPs exhibited enhanced tolerability, with attenuated inflammatory responses and a safety profile supportive of repeated dosing. These findings establish P3B-LNPs as a potent, safe, and biodegradable platform for genome editing in the brain and underscore the power of combinatorial lipid chemistry and high-throughput in vivo screening to accelerate the development of next-generation LNPs for CNS-targeted mRNA therapeutics.",

Here, we develop M@EFE NPs, a biomimetic nanomedicine, to alleviate the reperfusion injury. This nanomedicine is constructed by encapsulating Edaravone into the metal-phenolic nanoparticles self-assembled from epigallocatechin gallate (EGCG) and iron ions (Fe3+), and further coating with macrophage membranes. This design integrates the antioxidant and anti-lipid peroxidation properties of the EGCG-Fe3+ nanoparticles with the inflammatory targeting capacity of macrophage membranes. Following systemic administration, M@EFE NPs are able to penetrate the blood-brain barrier and target the ischemic regions, thereby inhibiting oxidative damage, protecting neurons, and ultimately improving stroke outcomes. In vitro, the nanomedicine can effectively scavenge reactive oxygen species, inhibit lipid peroxidation, and enhance cell survival.

In this study, a borneol-modified carboxymethyl chitosan nanoparticle system (BC/P/HCR NPs) was developed, aiming to codeliver curcumin, rosmarinic acid, and plasmid DNA (pDNA) targeting the SNCA gene for synergistic therapeutic intervention in PD. Borneol is capable of enhancing the permeability of the blood-brain barrier (BBB), while carboxymethyl chitosan contributes to improving the solubility of curcumin and preventing premature drug release. In a C57BL/6 mouse model of PD, BC/P/HCR NPs demonstrated enhanced penetration through the BBB, effectively alleviating motor dysfunction and reducing neuronal damage by downregulating the expression of \u03b1-synuclein, restoring mitochondrial function, and mitigating oxidative stress.

However, the exponential growth of literature in this domain presents challenges in grasping the holistic research trajectory and identifying emerging hotspots. This study conducted a comprehensive bibliometric analysis of 4,009 publications retrieved from the Web of Science Core Collection (WoSCC) spanning from 2000 to 2025. Tools including VOSviewer, CiteSpace, and R-bibliometrix were employed to map spatiotemporal trends, collaborative networks, and keyword evolution. The analysis reveals a robust upward trend in global research output, predominantly driven by China and the United States. Keyword clustering identified five major research sub-domains: Alzheimer's disease, Oxytocin (behavioral/psychiatric applications), Stroke and Neuroinflammation, Brain Tumors, and Nanoparticles. Burst detection analysis elucidates a distinct paradigm shift in scientific focus: early investigations prioritized mucosal absorption mechanisms and tolerance; the focus subsequently transitioned to specific therapeutic agents (e.g., insulin, oxytocin); and most recently, the field has been dominated by the optimization of delivery vectors, specifically lipid-based nanoparticles and exosomes. While nanotechnology has become the current technological frontier for enhancing brain targeting, a critical gap remains between promising preclinical results and clinical translation.

This narrative critical review is explicitly scoped to AD and PD, the only neurodegenerative conditions for which postmortem detection of gingipains in affected brain regions, mechanistic evidence from cellular and animal models, and clinical epidemiological data currently exist in sufficient depth to support an integrated synthesis. Robust meta-analyses confirm that periodontitis is associated with elevated AD/PD risk (OR/HR 1.2-3.5), while gingipains have been detected in a high proportion (>85-90%) of postmortem AD/PD brains, correlating with tau/\u03b1-synuclein pathology, neuroinflammation, and neuronal loss. Mechanistic studies in cellular and animal models demonstrate that gingipains can disrupt blood-brain barrier integrity via tight-junction cleavage, trigger NF-\u03baB/NLRP3-driven glial activation, catalyse amyloid-\u03b2/\u03b1-synuclein seeding, induce tau truncation/hyperphosphorylation, and precipitate mitochondrial oxidative damage, thereby generating self-amplifying neurotoxic cascades. Salivary gingipain activity offers a non-invasive, high-sensitivity biomarker candidate for early risk stratification that may outperform conventional fluid markers in prodromal cohorts. Therapeutically, small-molecule gingipain inhibitors have shown neuroprotective effects in preclinical models (e.g., atuzaginstat/COR388 failed primary endpoints in the Phase 2/3 GAIN trial but demonstrated subgroup benefits in P. gingivalis-positive participants; the next-generation inhibitor LHP588 is advancing in the Phase 2 SPRING trial). Emerging approaches including nanotechnology, CRISPR-based virulence gene disruption, and targeted delivery platforms aim to improve brain exposure and specificity. This review provides an integrated, isoform-resolved framework linking gingipain structure-function to neurodegeneration. While associative and mechanistic evidence is compelling, definitive causation in humans and disease-modifying efficacy require further validation through biomarker-guided clinical trials. Precision inhibition of gingipains represents a promising upstream strategy for addressing a potentially modifiable microbial contributor at the oral-brain interface.",

To overcome these hurdles, we engineered a genetically modified biomimetic \"nanosponge\" (CCR2@VCNPs) designed to synergistically sensitize radiotherapy (RT) and remodel the tumor microenvironment. The nanoplatform consists of a self-assembled core composed of Verteporfin and Celecoxib (VCNPs), which provides high drug loading capacity and enables coordinated delivery of both agents. By cloaking this self-assembled core with macrophage membranes overexpressing CC chemokine receptor 2 (CCR2), the nanoparticles achieve dual-mode targeting: mimicking leukocyte-endothelium interactions for BBB transcytosis and exploiting the CCL2/CCR2 axis for active chemotactic navigation. Notably, the surface CCR2 serves as a \"molecular decoy\" to intercept RT-induced CCL2, effectively blocking the infiltration of immunosuppressive myeloid cells. Upon tumor accumulation, the self-delivered Verteporfin acts as a potent radiosensitizer by generating singlet oxygen and inhibiting the YAP/TAZ pathway, while Celecoxib (CXB) concurrently abrogates radio-induced immunosuppression by severing the PGE2/COX-2 signaling axis. This integrated strategy promotes robust immunogenic cell death (ICD), effectively transforming the \"cold\" GBM niche into a \"hot\" immunological phenotype. In orthotopic GBM mouse models, CCR2@VCNPs significantly prolonged median survival and suppressed tumor recurrence. By integrating molecular self-assembly with genetic membrane engineering, offers a comprehensive solution to therapeutic resistance and holds great promise for clinical GBM management.",

We investigated macroscopic structural-functional coupling abnormalities in early-stage ALS (ALS-ES) and their underlying transcriptomic signatures. We analyzed multimodal MRI data from 73 patients with sporadic ALS-ES and 74 age- and sex-matched healthy controls. Structural-functional (SC-FC) coupling was quantified using diffusion tensor imaging and resting-state functional MRI. Machine learning models were constructed to distinguish patients from controls based on network features. Coupling alterations were spatially correlated with neurotransmitter receptor maps and gene expression profiles from the Allen Human Brain Atlas. Key transcriptomic findings were validated using independent single-cell RNA sequencing datasets. While structural connectivity remained largely preserved, functional connectivity was significantly reduced in the somatomotor network (SMN). This mismatch manifested as significant SC-FC network decoupling, particularly within the SMN (pFDR = 0.001). A gradient boosting machine model accurately classified patients, identifying SC-FC coupling in the left precentral gyrus as a primary statistical contributor to the classification model. Decoupling spatially correlated with 5-HT2A and mGluR5 receptor distributions. Imaging-transcriptomics linked network failure to a gene signature enriched for synaptic pathways and microglial markers. Single-cell analysis identified FMN1 as a candidate gene whose glial expression spatially associates with network decoupling. Early-stage ALS is characterized by significant structural-functional network decoupling, primarily in motor systems. This macroscopic failure is linked to specific microglial dysregulation, particularly FMN1 downregulation, providing a multiscale framework bridges statistical neuroimaging signatures with potential cellular pathology.",

While embryonic patterning establishes the initial positional and molecular framework of motor neuron identity, substantial refinement continues during early postnatal life as intrinsic electrophysiological properties, synaptic connectivity, and neuromuscular interactions mature. A major limitation in the field is the lack of temporally stable and functionally validated molecular markers that can reliably distinguish motor neuron subtypes across developmental stages, particularly during neonatal maturation when subtype-specific physiological features are emerging. In this review, we synthesize classical developmental studies with recent advances in single-cell transcriptomics, chromatin accessibility profiling, and multimodal approaches linking gene expression with electrophysiological and anatomical features. Focusing on lumbar spinal motor neurons that underlie locomotor behavior, we discuss how transcriptional programs, activity-dependent mechanisms, and non-cell-autonomous signals converge to shape subtype-specific maturation trajectories. We propose that motor neuron subtype identity is best understood as a dynamic molecular and physiological state shaped by developmental timing, circuit context, and activity-dependent mechanisms, rather than as a fixed category defined by a single marker. From this perspective, early postnatal life represents a sensitive window of identity consolidation during which molecular programs and functional properties become aligned. Establishing temporally robust subtype markers and integrating molecular and physiological datasets will be essential for resolving motor neuron diversity and for improving our understanding of subtype-selective vulnerability in neuromuscular diseases. While this review emphasizes embryonic and early postnatal development, understanding how molecular subtypes stabilize in the adult spinal cord, despite ongoing activity-dependent physiological plasticity, remains an essential reference point for defining temporally robust motor neuron identities.",

Initially considered by-products of splicing, circRNAs are now recognised as an important class of regulatory RNAs involved in microRNA sponging, RNA-protein interactions, and cellular pathways. Their closed-loop structure, generated through backsplicing, confers resistance to exonucleolytic degradation and contributes to their stability. Owing to their tissue- and disease-specific expression, circRNAs have emerged as promising biomarkers for cancer, neurodegenerative disorders, and cardiovascular disease. Over the past decade, numerous bioinformatics tools utilising RNA-sequencing (RNA-seq) data have been developed for circRNA detection and analysis. Detection methods have evolved from manual split-read inspection to automated identification of the back spliced junction, while annotation pipelines now resolve the genomic origins and structural characteristics of circRNAs. Because individual circRNA callers vary considerably in sensitivity and specificity, a combined usage of tools in circRNA detection has become the preferred strategy for generating high-confidence datasets. Beyond their non-coding functions, increasing evidence suggests that some circRNAs possess protein-coding potential through open reading frames, cap-independent translation mechanisms, internal ribosome entry sites (IRESs), and N6-methyladenosine modifications. A new generation of bioinformatic tools can now assess the protein-coding potential of circRNAs, integrating the above features, as well as machine learning and deep learning approaches refining these predictions. This review summarises recently developed short-read RNA-seq bioinformatics tools for circRNA detection, consensus calling, annotation, and protein-coding potential prediction, with a particular focus on advances from the past five years that facilitate the identification of translatable circRNAs.",

"42397593": "ID: 42397593\nTitle: Network toxicology and multi-omics identify potential interactions between between air pollutants and interferon-related signaling in tuberculosis.\nAbstract: Air pollution increases tuberculosis (TB) susceptibility, yet the underlying molecular mechanisms remain elusive. We integrated human genes associated with seven air pollutants with TB-associated genes from public databases. Utilizing network toxicology, we engineered a diagnostic pipeline evaluating 175 machine learning models across transcriptomic datasets to identify a core gene signature. This signature was validated via qPCR in an independent clinical cohort. Molecular docking and in silico single-cell knockout analyses were used to predict pollutant-protein interactions and potential downstream transcriptional perturbations. We identified 271 intersecting genes enriched in inflammatory and immune-related pathways, including IL-17, TNF, and Toll-like receptor signaling. Machine learning identified a five-gene candidate signature consisting of STAT1, IFIH1, IFIT2, IFIT3, and CYBB. Clinical qRT-PCR further supported their upregulation in TB patients, with individual AUCs ranging from 0.76 to 0.89. Docking simulations predicted that toluene may form hydrophobic interactions with STAT1, IFIT2, and IFIT3. In silico STAT1 perturbation in monocytes predicted transcriptional alterations involving RETN and S100A9, with enrichment in IFN-\u03b3-related pathways. Air pollutants, particularly toluene and benzene, may contribute to TB susceptibility by interacting with interferon-related immune proteins. The identified five-gene signature may represent a potential biomarker panel for TB and warrants further validation in exposure-characterized cohorts.",

The roles of SEMA5B in prostate cancer remain underexplored. This study investigates SEMA5B's functions in prostate cancer, revealing its role as a tumor suppressor transcriptionally regulated by androgen receptor and uncovering novel biomarkers and potential immunotherapeutic mechanisms. We analyzed SEMA5B's expression in cancer and its spatial association with cells in the tumor microenvironment using single-cell transcriptome sequencing datasets and spatial transcriptome sequencing samples. Using bulk RNA-seq data, we analyzed the immune infiltration of SEMA5B in prostate cancer. The association of SEMA5B with androgen receptor signaling and with metabolic pathways was evaluated by transcriptome and enrichment analysis. The phenotypes, cell cycle, apoptosis, and mitochondrial metabolic function of prostate cancer cell lines were further evaluated. SEMA5B regulation by androgen receptor was examined by gene knockdown, androgen/enzalutamide treatment, and epigenomics. Finally, the effect of SEMA5B on prostate cancer in\u00a0vivo was detected by tumor xenograft model. Pan-cancer single-cell analysis revealed that SEMA5B's expression showed significant tumor type specificity and spatially correlated with immune cell infiltration. SEMA5B is associated with abundant lymphocyte and immune-inflammatory microenvironment in prostate cancer. SEMA5B overexpression inhibited tumor cell proliferation, migration, and invasion. Moreover, high SEMA5B is associated with oxidative phosphorylation and low glycolytic profile. SEMA5B expression is positively correlated with androgen receptor. Androgen receptor inhibition and androgen stimulation affected the expression of SEMA5B. ChIP confirmed the binding of androgen receptor to the SEMA5B promoter. Finally, SEMA5B was verified to induce cell cycle arrest and apoptosis and reduce tumor growth. SEMA5B inhibits tumor malignant phenotype and is associated with immune-inflammatory tumor microenvironment. SEMA5B can regulate mitochondrial oxidative metabolism and induce cell cycle arrest and cell apoptosis, inhibiting the growth of prostate cancer.",

Despite its pathological role, effective therapies remain limited by the lack of safe, potent molecules targeting TDP-43 neurotoxicity. Here we show that the conserved \u03b1-helical region spanning residues 320-340 (conserved region or CR) is a therapeutically actionable target for TDP-43 neurotoxicity. Deletion of CR markedly suppressed TDP-43-induced neuronal death. Structure-based virtual screening identified XL20, a brain-penetrant small molecule that engages CR and confers neuroprotection without affecting TDP-43 splicing activity. XL20 alleviated motor neuron loss, extended survival in TDP-43 p.Ala315Thr ALS mice and enhanced neuronal function in p.Gln331Lys induced pluripotent stem cell-derived human ALS motor neurons. Mechanistically, targeting CR suppressed TDP-43 mitochondrial localization and restored mitochondrial function, likely through liquid-liquid phase separation. Our findings highlight CR as a therapeutic target for TDP-43-associated neurodegeneration and support CR-binding small molecules as therapeutic candidates.",

COVID-19-associated GBS (COVID-GBS) is a rare but severe post-infectious condition, and its immune mechanisms remain unclear. We profiled immune mediators in cerebrospinal fluid (CSF) and serum from COVID-GBS patients, comparing them to non-COVID GBS (Control-GBS), COVID-19 patients without neurological complications (COVID-no-GBS) and non-inflammatory neuropathy controls (Neuropathy-no-GBS). To gain mechanistic insights, we integrated publicly available single-nucleus transcriptomic data from sural nerve biopsies of neuropathy patients. IL-8 was confirmed as a key cytokine in GBS. Analysis of publicly available single-nucleus transcriptomic data from non-GBS sural nerve biopsies suggested myeloid cells as potential sources of IL-8, with evidence of autocrine signaling capacity. LIF and CD8A emerged as novel biomarkers, with this transcriptomic analysis indicating that LIF receptor components are expressed on endothelial and stromal cells, suggesting these as potential cellular targets. COVID-GBS patients exhibited unique CSF alterations and distinct serum profiles marked by altered NK cell activity, cytotoxic T-cell responses, and myeloid differentiation. Moreover, associations between inflammatory, extracellular matrix, and regulatory markers with clinical disability differed between COVID-GBS and Control-GBS, pointing to divergent immune mechanisms. Our findings suggest that GBS involves myeloid-driven cytokine responses and local LIF signaling. Analysis of publicly available transcriptomic data from non-GBS sural nerve biopsies suggests potential cellular sources and targets, though validation in GBS-affected tissue is needed. COVID-GBS features a distinct immune signature involving localized and systemic inflammation. These insights deepen our understanding of GBS pathogenesis and nominate candidate biomarkers for further validation and potential therapeutic targeting.",

Quercetin (QR), a natural flavonoid, exerts antioxidant and anti-inflammatory effects by modulating the Nrf2-Keap1 pathway and shows neuroprotective potential in various neurological disorders. In this study, network pharmacology analysis identified 496 overlapping targets of QR and TBI, further highlighting the pivotal role of the Nrf2-Keap1 pathway in TBI treatment. However, the poor blood-brain barrier (BBB) permeability and low bioavailability of QR hinder effective brain-targeted delivery and limit its clinical translation. To address these challenges, we developed CAQK peptide-modified, reactive oxygen species (ROS)-responsive nanoparticles (C-PPS/Q), using PPS120 as the core for targeted QR delivery. C-PPS/Q exhibited ROS-triggered QR release, significantly enhanced HT22 cell uptake in\u00a0vitro, reduced ROS levels and apoptosis. In a TBI mouse model, C-PPS/Q specifically accumulated at the lesion site, prolonged the half-life of QR, demonstrated excellent biocompatibility, preserved BBB integrity, attenuated neuroinflammation, inhibited aberrant Nrf2-Keap1 pathway activation, and markedly improved neurological function. Collectively, C-PPS/Q nanoparticles effectively mitigate secondary brain injury after TBI and represent a promising brain-targeted therapeutic strategy for TBI management.",

Numerous computational prediction tools have been developed and aim to analyze and predict chimeric RNAs. However, the performance of these tools vary in accuracy and depend on the sequencing context, necessitating a combination of multiple existing tools to produce the most comprehensive and accurate results. First, this study reviews several major chimeric RNA prediction tools: STAR-Fusion, Arriba, and FuSeq. It highlights the advantages of each program, as demonstrated by benchmarking studies. Second, it presents an integrated pipeline that combines all three top-ranking programs to produce a single output file including detailed annotations, such as chimeric RNA class, breakpoint types, and protein coding potential.

In addition to the mechanisms above, we have identified a new type of chimeric RNA, cross-strand chimeric RNA (cscRNA), which are fusion products of the transcripts encoded by the two opposite DNA strands. In this chapter, we present the workflow of cscMap, a specialized bioinformatics pipeline designed for de novo identification of the cscRNAs, directly from RNA deep sequencing data without prior annotations. cscMap employs a series of meticulous measurements to ensure high accuracy in detecting cross-strand junction events. This approach and the cscRNA species could serve as a valuable resource for further exploration of the origins and functions of cscRNAs.",

This chapter introduces an integrative framework for high-confidence chiRNA identification leveraging the ChiTaRS 8.0 database and the ChiTaH pipeline. ChiTaRS 8.0 encompasses 47,445 human chiRNAs, 1,055 Hi-C breakpoints, and 1,598 drug targets, while ChiTaH facilitates disease-specific analysis of RNA-seq data from 250 peripheral blood mononuclear cell (PBMC) samples-including glioblastoma and oral squamous cell carcinoma-and 199 healthy controls. Our approach combines reference-based fusion detection, BLAT validation against GRCh38, gene-pair compatibility checks, and protein domain conservation analysis. Functional annotation and protein-protein interaction modeling uncovered oncogenic chiRNAs absent from existing databases, exhibiting tissue-specific patterns. In Alzheimer's disease, liquid biopsy analyses identified unique chimeras-such as ENO1-MCUR1 and APOE-APOE-in cerebrospinal fluid, linked to neurotransmitter pathways and amyloid processing, and absent in healthy samples, highlighting their potential as early biomarkers. We describe a scalable digital hospital framework integrating AI-driven fusion detection, relational databases, and clinical metadata for real-time diagnostics and patient monitoring. This system supports fusion-targeted drug discovery and patient stratification, bridging translational gaps in oncology and neurodegeneration. By coupling computational pipelines with multiomics data, our approach advances personalized medicine while addressing challenges in artifact filtering and functional validation. Ultimately, the ChiTaRS-ChiTaH platform offers a versatile tool for chiRNA discovery and annotation across diverse disease contexts, providing insights into molecular mechanisms and clinical applications.",

Definitionally, chimeric RNAs exist within gaps in annotation, and most efforts to catalog chimeric RNAs at scale have leveraged short-read paired-end RNAseq. While these have successfully established putative \"chimeromes\" in different tissue and disease contexts, chimeric RNAs predicted via short-read sequencing are defined by the chimeric exon-exon junction, and cannot provide information on the full-length isoforms which contain this junction. These gaps can be remedied by integration of these predictions with full-length, single-molecule, long-read sequencing. In this chapter, we provide instruction on how to integrate long-read sequencing with existing chimeric RNA predictions to establish full-length annotations of long-read transcripts.",

These chimeric RNAs have been shown to play functional roles in both disease states and normal physiological processes, underscoring their biological relevance. Despite this, there are currently a limited number of tools available that aim to quantify chimeric RNA expression. Here, we introduce a metric called the Relative Index of Chimeric Expression (RICE), which assesses the expression of chimeric transcripts relative to their corresponding wild-type parental transcript, and we describe an easy-to-use bioinformatic tool called FusionBlaster for calculating RICE values from RNA sequencing data.

Here, we developed a rationally designed PLGA-based dual-loaded nanoformulation co-encapsulating USP7 inhibitor P5091 and P53-modulating polyphenol Resveratrol, to significantly attenuate the USP7-MDM2-P53 axis. Guided by synergy analysis, nanoparticles were formulated at an optimized molar ratio enabling controlled and sustained drug release with favourable physicochemical stability. Dual nanoencapsulation significantly enhanced synergistic cytotoxicity in glioma cells and 3D spheroids by inducing apoptosis through significant P53 restoration. Dual co-encapsulation improves pharmacokinetics and suppresses tumor growth with improved survival in orthotopic glioma model without any obvious vital organs histological damage.

"42402496": "ID: 42402496\nTitle: A multi-scale graph frequency network for structural and functional region analysis in spatial transcriptomics.\nAbstract: Spatial transcriptomics enables the systematic exploration of how gene expression patterns are organized within intact tissues, yet effective analysis remains difficult due to the complexity of spatial dependencies and multi-scale tissue architectures. Here, we present the Spatial Graph Frequency Network (SGFN), a deep learning framework that integrates graph signal processing, graph attention, and contrastive learning to jointly model spatial topology and molecular features. Central to SGFN is a frequency-domain enhancement module that decomposes spatial graphs into multi-scale spectral components using the Laplacian eigenbasis, complemented by adaptive wavelet denoising when the retained graph-frequency sequence length permits valid decomposition. Evaluation across diverse biological systems-including the human dorsolateral prefrontal cortex, mouse brain, human breast cancer, osmFISH, MERFISH, STARmap, mouse embryonic development, head and neck angiosarcoma, and brain metastasis-shows that SGFN achieves improved or competitive performance relative to representative baseline methods in reference-based benchmarks, and identifies biologically coherent spatial or functional regions in unlabeled datasets supported by marker-gene, spatial-autocorrelation, cell-type-colocalization, and pathway-enrichment evidence. SGFN accurately reconstructed cortical layer architecture in the human brain, delineated immune and metabolic modules in tumors, and revealed spatiotemporal trajectories during embryogenesis. By combining interpretable frequency-domain representations with data-driven learning, SGFN provides a unified computational framework for decoding tissue organization and molecular heterogeneity, advancing the understanding of developmental, physiological, and pathological spatial systems.",

Propylene glycol was chosen as co-surfactant, Tween 80 as surfactant, and peppermint oil as oil phase after excipients screening, as this combination exhibited the broadest emulsification region in pseudo-ternary phase diagram. A systematic Quality-by-Design (QbD) approach was adopted, and formulation variables were optimized using Design-Expert software to obtain an optimized L-SNEDDS formulation with desirable physicochemical attributes. Dilution of the optimized SNEDDS led to the spontaneous formation of a stable aqueous nanoemulsion exhibiting a droplet size of 110.9\u2009nm, polydispersity index (PDI) 0.265, transmittance of 98.86\u2009\u00b1\u20090.37%, zeta potential of -16.3\u2009mV, viscosity of 6.35\u2009\u00b1\u20092.51\u2009cP, self-emulsification time of 27.35\u2009s, and conductivity of 196.23\u2009\u00b1\u20090.324 \u03bcS cm-1. In vivo studies showed that SEL-BCA-loaded SNEDDS exhibited better oral bioavailability than pure SEL-BCA suspension. Notably, SNEDDS achieved higher brain Cmax values for SEL (5.6\u2009\u00b1\u20090.41\u2009\u03bcg\u2009mL-1) and BCA (13.84\u2009\u00b1\u20091.14\u2009\u03bcg\u2009mL-1), as well as elevated plasma concentrations of SEL (6.51\u2009\u00b1\u20090.43\u2009\u03bcg\u2009mL-1) and BCA (762.65\u2009\u00b1\u200916.82\u2009\u03bcg\u2009mL-1).

This mechanism-oriented integrative review examines how engineered nanosystems may move beyond brain entry toward lesion-directed modulation of the neuroinflammation-barrier-neuroplasticity axis. We first synthesize the pathological nodes that sustain depression-related network dysfunction and then classify current nanotherapeutic strategies into three categories: small-molecule nanodelivery systems, nucleic acid nanocarriers, and functional nanoplatforms, including lipid and polymeric nanoparticles, inorganic and nanozyme-based systems, biomimetic membrane-coated nanoparticles, and engineered extracellular vesicles, including exosomes. Unlike previous nanosynthesis-focused or catalogue-style nanocarrier reviews, this review organizes the field around a disease-mechanism framework rather than material type alone, emphasizing barrier-state navigation, glial-neuronal-subcellular targeting, stimulus-responsive release, and coordinated modulation of inflammation, vascular integrity, redox homeostasis, and synaptic plasticity. We further argue that nanoplatforms should be evaluated not only by brain accumulation but also by patient stratification, engagement of defined pathological nodes, multimodal biomarker evidence of network-level modulation, manufacturability, and safety under repeated administration. Major translational bottlenecks include insufficient subtype-specific patient selection, limited human relevance of current stress- and inflammation-based models, uncertain biodistribution and long-term neurotoxicity, constraints in scaling up nose-to-brain delivery, batch-to-batch variability, cargo instability, immunogenicity, and unclear regulatory classification of complex biologic or combination products. Finally, we propose a pathological-network-guided precision nanomedicine framework that integrates blood-brain barrier status assessment, liquid biopsy and imaging biomarkers, human-relevant validation models, and scalable quality control to guide future platform design and clinical translation. This review provides a disease-mechanism-centered roadmap for transforming nanomedicine for depression from delivery optimization into precision network-oriented intervention.",

Decades of limited therapeutic progress underscore the need for new treatment strategies beyond conventional modalities. Magnetic nanoparticles have emerged as a promising theranostic platform that integrates high-precision imaging, targeted delivery, and synergistic therapy. In this review, we outline a mechanistic framework for magnetic nanoparticle applications, with a focus on the link between ferroptosis and immune activation. We discuss how the intrinsic properties of magnetic nanoparticles can be engineered to induce iron-dependent ferroptotic cell death, which may help overcome apoptosis resistance and also trigger immunogenic cell death. This magnetic nanoparticle-induced immunogenic cell death may shift the immunosuppressive brain tumor microenvironment from a \"cold\" state toward a more immune-active phenotype, thereby supporting combination immunotherapy. We also examine key translational challenges and potential solutions, including quantitative magnetic particle imaging-guided therapeutic dosimetry, focused ultrasound-mediated delivery strategies, and issues related to Chemistry, Manufacturing, and Controls and regulatory science. By analyzing these translational challenges, this review aims to highlight practical considerations for advancing magnetic nanoparticle-based therapies toward clinical neuro-oncology.",

This study is aimed at identifying potential therapeutic targets for DR. Transcriptomic and proteomic data were obtained from the Gene Expression Omnibus (GEO) and ProteomeXchange databases, respectively. Differentially expressed genes (DEGs) and differentially expressed proteins (DEPs) were intersected. An enrichment analysis of the overlapping genes was performed based on the DAVID database. A protein-protein interaction (PPI) network (STRING) was analyzed via Cytoscape/cytoHubba to identify key genes. Single-cell RNA-sequencing (scRNA-seq) data were processed using Seurat. Gene set enrichment analysis (GSEA) (clusterProfiler) and molecular docking (EnrichR) were performed. High glucose-induced retinal microvascular endothelial cells (RMECs) were used for functional assays. The intersection of DEGs and DEPs yielded shared genes, enriched in the PI3K-Akt signaling pathway, AGE-RAGE signaling pathway in diabetic complications, complement and coagulation cascades, and ECM-receptor interaction; a PPI network incorporating these genes revealed two key DR-associated highly expressed genes, COL1A1 and SERPINE1. GSEA showed that samples with high expression of these key genes were enriched in pathways such as reactome signaling by TGFB family members, inflammatory response, TGF-\u03b2 signaling, and reactome cell extracellular matrix interactions. Single-cell and molecular docking analyses revealed high expression of the two key genes in fibroblasts and binding between SERPINE1 and paricalcitol, and HG induction increased their levels in RMECs, whereas knockdown of SERPINE1 repressed RMEC proliferation, migration, and invasion in vitro. This study identifies SERPINE1 and COL1A1 as possible DR therapeutic targets, providing new insights into relevant therapeutic development.",

Although single-omics studies have provided partial insights into AP pathogenesis, comprehensive integrative multi-omics analyses investigating the intricate interactions among immunity, metabolism, and the microbiome in AP remain limited. We conducted an integrative multi-omics analysis of peripheral blood transcriptomics, untargeted plasma metabolomics, and fecal whole-metagenome sequencing in 15 patients with AP and 15 age- and sex-matched healthy controls. Differentially expressed genes (DEGs), metabolites (DEMs), and gut microbial species (DGMs) were identified. Subsequently, functional enrichment analysis, correlation network analysis, and exploratory machine learning approaches were employed to investigate molecular interactions and identify candidate biomarkers. Transcriptomic profiling identified 4, 776 DEGs, including 409 immune-related genes significantly enriched in the NF-\u03baB, IL-17, and cytokine-cytokine receptor interaction pathways, indicating pronounced inflammatory activation. Metabolomic analysis detected 296 DEMs, with prominent alterations in amino acid and lipid metabolism, mong which 9 metabolites showed potential discriminatory value (AUC > 0.75), with representative metabolites including xanthine, homocarnosine, and tetradecanedioic acid. Metagenomic sequencing revealed significant microbial compositional and functional remodeling, characterized by enrichment of pro-inflammatory taxa such as Escherichia coli and Streptococcus anginosus, alongside depletion of SCFA-producing commensals including Faecalibacterium prausnitzii and Blautia wexlerae. Functional profiling demonstrated disrupted amino acid metabolism, gut-brain signaling, and SCFA synthesis. Multi-omics integration revealed 215 significant correlations between host genes, metabolites, and microbes, highlighting key interaction hubs. An exploratory random forest model identified Lachnospira pectinoschiza, Megamonas funiformis, and SRGN as candidate biomarkers, showing promising classification performance within the current cohort (AUC = 0.951). This study provides a systems-level characterization of the immune, metabolic, and microbial alterations in AP.

This study aimed to identify key PA-related genes (PARGs) in ulcerative colitis (UC), and explore their transcriptional associations with immune-stromal dysregulation. Transcriptomic data of UC patients were obtained from the GEO database, and PARGs were retrieved from the MSigDB database. Differential expression analysis, WGCNA, LASSO, SVM-RFE, and random forest algorithms were applied to the GSE87466 dataset to identify key genes. Functional enrichment and immune infiltration analyses were performed to characterize their biological features. Additionally, single-cell RNA sequencing (scRNA-seq) analysis of the GSE214695 dataset was conducted to clarify their expression and localization. Findings were validated using independent GEO cohorts (GSE47908, GSE38713, and GSE36807) and qRT-PCR in a dextran sodium sulfate (DSS)-induced colitis mouse model. We identified 22 PARGs in UC, which were associated with extracellular matrix (ECM) remodeling, platelet activation, and immune cell recruitment. Machine learning algorithms refined these to three key genes: SPARC, TIMP1, and SERPINA1. ROC analysis demonstrated robust diagnostic performance (AUC\u00a0> 0.8) across the training and external validation cohorts. Crucially, single-cell analysis revealed that these genes were predominantly expressed in intestinal fibroblasts. Their expression levels strongly correlated with the infiltration of pathogenic immune cells (e.g., M1 macrophages, neutrophils). Additionally, an upstream regulatory network predicted transcription factors such as NFKB1 and SP1 as potential regulators. Finally, qRT-PCR confirmed the significant upregulation of these three genes in the DSS-induced colitis model. This study highlights the role of platelet activation in UC; identifies SPARC, TIMP1, and SERPINA1 as potential biomarkers; and provides important insights for the diagnosis and development of therapies for UC.",

This study aimed to elucidate how cone opsin dysfunction translates into molecular and functional susceptibility to myopia. Retinal transcriptome and metabolome sequencing were performed in Opn1mw\u207b/\u207b (MKO), Opn1sw\u207b/\u207b (SKO), and wild-type (WT) mice. To assess susceptibility to lens-induced myopia (LIM), the right eyes of MKO and WT mice were fitted with -25 D lenses. In a rescue experiment, MKO mice were treated with the dopamine (DA) D1 receptor agonist SKF38393 hydrochloride. Refractive error, ocular biometry, and retinal DA levels were assessed. Retinas from WT mice and MKO mice with and without lens-wearing were collected for proteomic profiling. Differentially expressed genes and proteins were analyzed by Kyoto Encyclopedia of Genes and Genomes and STRING database. Selected targets were validated by quantitative PCR and Western blotting. Both MKO and SKO mice developed significant hyperopic shifts, with extensive transcriptomic and metabolic remodeling. When subjected to LIM, MKO mice exhibited exacerbated myopic shifts and lower retinal DA levels. Integrated proteomic analyses identified dopaminergic synapse-related alterations shared by Opn1mw deletion and lens-induced defocus. A convergent protein network involving TFAM, KDM5C, and SMN1, molecules linked to mitochondrial homeostasis, chromatin regulation, and RNA processing/neuronal maintenance, was consistently downregulated by M-opsin deficiency and further exacerbated by lens-induced defocus. Pharmacological activation of D1 receptors with SKF38393 attenuated LIM in MKO mice and increased TFAM and SMN1 protein levels, providing functional support for the involvement of impaired dopaminergic signaling in the enhanced myopia susceptibility of MKO mice. M-opsin dysfunction is associated with reduced retinal dopaminergic tone and increased susceptibility to LIM, consistent with a gene-environment dual-hit framework. A dysregulated TFAM/KDM5C/SMN1-associated molecular network may mark a vulnerable retinal state predisposing the eye to environmentally induced myopia.",
"42406553": "ID: 42406553\nTitle: EphB1-Mediated Transient Blood-Brain Barrier Opening Facilitates a Ferritin-Based Nanotherapeutic for Alzheimer's Disease.\nAbstract: The treatment of Alzheimer's disease (AD) is severely hampered by the blood-brain barrier (BBB), which limits the delivery of therapeutic agents like donepezil (DPZ), an acetylcholinesterase inhibitor. While DPZ has multi-faceted benefits, its clinical efficacy is constrained by poor BBB penetration, requiring high doses that lead to significant side effects. To overcome this, we developed a brain-targeted nanotherapeutic utilizing apoferritin (AFn) nanoparticles loaded with DPZ (AFn-DPZ). We demonstrate that this platform, by binding to the EphB1 receptor on the blood-brain barrier, enables transient and reversible opening of the blood-brain barrier, thereby facilitating efficient and targeted drug delivery. Following intravenous administration in an AD mouse model, AFn-DPZ exhibited enhanced brain accumulation and sustained release of DPZ. This targeted delivery inhibited acetylcholinesterase activity, reduced amyloid plaque burden, alleviated neuroinflammation, attenuated oxidative damage, restored mitochondrial function, and upregulated the expression of brain-derived neurotrophic factor (BDNF). Consequently, AFn-DPZ treatment significantly improved cognitive performance compared to free DPZ. Our findings establish EphB1-mediated facilitation of BBB traversal as a promising strategy for enhancing nanotherapeutic delivery to the brain, offering a potent approach to address the complex pathology of AD.",

We assessed a carbosilane dendrimer (G3Si PEG6000) and its siRNA dendriplex using a tiered, upstream strategy spanning cell internalization, DNA damage screening, BBB model integrity and permeability, and in vivo AD-relevant murine model learning. At the cellular level, the dendrimer enhanced intracellular siRNA-associated signal with predominantly cytoplasmic localization, and siRNA complexation attenuated genotoxicity relative to the noncomplexed carrier. In a BBB triculture model, barrier function was preserved without sustained transendothelial electrical resistance (TEER) loss, and complementary tracer flux readouts showed time- and formulation-dependent, nonmonotonic changes, including TEER-permeability decoupling consistent with nonuniform perturbation and time-dependent changes in barrier-associated paracellular responses. In APOE4 knock-in mice, dendriplex treatment increased platform-zone crossings in the Morris Water Maze probe trial, whereas target-quadrant time showed only a modest, nonsignificant trend. Collectively, these integrated results indicate that siRNA complexation improves the BBB-relevant safety-performance balance of G3Si PEG6000 and supports further studies that directly link brain exposure and target engagement to cognitive outcomes.",

Current methods of detecting ferroptosis rely primarily on experimental techniques that are typically low-throughput and costly, limiting their clinical applications. Here we develop an effective statistical method, FerroScore, to quantify ferroptosis by generating a score that integrates the activities of three core pathways-iron, glutathione, and lipid metabolism. This method enables the cross-resolution assessment of ferroptosis and provides mechanistic insights into tumor, immune, and neurodegenerative diseases, thus having potential applications in targeted therapy and drug discovery. When applied to pancreatic cancer transcriptomic data, FerroScore reveals: (i) a U-shaped relationship between ferroptosis and patient survival; (ii) heterogeneous ferroptosis activity across cell types in the tumor microenvironment, with high sensitivity to Macrophages, CD8 Tcm cells, and a population of nCAFs; (iii) the role of ferroptosis-active cells in reshaping the immunosuppressive and pro-metastatic microenvironment through intercellular communication.",

Current foundation models have achieved superior performance compared with traditional methods. However, due to data sparsity and the complexity of model, existing methods often compromise by selecting highly variable genes or filtering for nonzero expressions, which discard potentially significant genes. Thus, modeling the complete transcriptome for cell representation remains computationally challenging; we present scGenoByte, a unified framework designed to enhance cell representation learning through biologically informed full-gene modeling. To enable efficient modeling of the full transcriptome, we design GenoBytes, biologically coherent units that are constructed by leveraging biological priors in terms of protein-protein interaction network and gene paralogy network. Furthermore, considering that the information of protein and pathway is critical for analyzing cell functions and representation, scGenoByte encapsulates biological priors by harmonizing GenoByte embeddings with protein representations and leveraging an auxiliary task of pathway activity prediction to impose pathway-guided regularization. Extensive results on eight datasets have shown that scGenoByte achieves better performance than competing methods, which confirms the efficacy of combining full-gene context with biological priors.",

Current therapies are primarily symptomatic and have not consistently demonstrated prevention of disease progression. This review introduces Programmable gene modulation networks, a systems-level framework that integrates CRISPR/Cas technologies with nanotechnology-enabled brain delivery for precision intervention in Parkinson's disease. Advanced CRISPR modalities, including CRISPR interference, activation, base editing, prime editing, and epigenetic editing, are evaluated for reversible and targeted modulation of disease-relevant gene networks. Non-viral nanocarrier platforms, such as lipid nanoparticles, polymeric systems, and exosome-mimetic vesicles, are discussed for overcoming blood-brain barrier limitations and improving brain-specific delivery. The review further emphasizes translational challenges, including delivery efficiency, off-target effects, long-term safety, manufacturing scalability, and regulatory considerations. By integrating molecular network biology, programmable gene regulation, and translational decision-making, this review provides a roadmap for developing next-generation disease-modifying therapies for Parkinson's disease.",

However, its involvement in postharvest disease resistance of fruit is still poorly defined. In the present study, we identified an RNA demethylase, CsALKBH8, and investigated its function in citrus defense against green mold. We found that Penicillium digitatum infection significantly reduced global m6A levels in citrus peel, accompanied by rapid induction of CsALKBH8 expression. In vitro assays confirmed that CsALKBH8 possesses m6A demethylase activity. Transient overexpression of CsALKBH8 in citrus peel markedly alleviated disease development, as reflected by lower infection severity and smaller lesions after pathogen challenge. Transcriptome analysis revealed that CsALKBH8 overexpression induced extensive reprogramming of gene expression, with significant enrichment of defense-related pathways, including reactive oxygen species (ROS) metabolism, phenylpropanoid biosynthesis, and plant-pathogen interaction. Furthermore, CsALKBH8 reduced m6A levels on transcripts of multiple defense-related genes, including CsPR-1, CsPODs, CsRBOHF, CsGSTs, and lignin biosynthesis-associated genes, thereby enhancing their expression. This epitranscriptomic regulation promoted the activation of ROS metabolism and lignin accumulation, leading to increased enzyme activities (NOX, SOD, POD, APX, GST, and LAC) and elevated levels of H2O2, O\u2082-, and lignin, ultimately strengthening disease resistance in citrus fruit. Collectively, our findings demonstrate that CsALKBH8 enhances citrus resistance to P. digitatum through m6A-dependent post-transcriptional regulation of defense pathways, highlighting its potential as a molecular target for improving fruit storage quality and postharvest disease control.",

This study aimed to systematically evaluate multi-omics factors potentially associated with UC susceptibility and identify reliable diagnostic biomarkers. A two-sample Mendelian randomization (MR) framework assessed potential causal associations between gut microbiome, circulating metabolites, immune cell phenotypes, and UC susceptibility. Significant MR findings were integrated with multiple transcriptomic datasets to identify differentially expressed candidate genes. Immune infiltration analysis, machine learning modeling, and external validation were subsequently performed. Single-cell and spatial transcriptomics were used to localize key genes and to explore their potential cell type-specific functions within the tissue microenvironment, followed by qRT-PCR validation in independent clinical tissues and siRNA-mediated IFITM2 knockdown in THP-1-derived macrophages. MR analyses identified potential causal associations for specific microbiota, sphingomyelin-related metabolites, and immune cell phenotypes with UC susceptibility. Integrative analysis prioritized four core signature genes: SAG, WDR48, IFITM2, and SIRPA. A random forest model achieved an AUC of 0.964 and identified a four-gene signature with strong diagnostic performance. Single-cell and spatial transcriptomics localized IFITM2 upregulation mainly to myeloid cells, particularly Neutrophil_IFITM2. CellChat suggested a potential CD4_Tem_IL7R-ANXA1-FPR1-Neutrophil_IFITM2 axis. qRT-PCR supported the expression directions of the four genes, and IFITM2 knockdown in THP-1-derived macrophages reduced TNF-\u03b1, IL-6, and IL-1\u03b2 mRNA expression. This multi-omics framework supports the potential roles of specific microbiota, sphingolipid metabolism, and immune phenotypes in UC pathogenesis. The four-gene signature and characterization of Neutrophil_IFITM2, supported by independent qRT-PCR validation and preliminary IFITM2 knockdown experiments, may provide a framework for precision diagnosis and future mechanistic studies in UC.",

It primarily affects the elderly population. The disease is marked by progressive neuronal damage, leading to impairments in cognition, behavior, emotions, and communication. Although currently available therapies provide symptomatic relief, they fail to alter disease progression, necessitating the development of more effective therapeutic strategies. Phytoconstituents have gained considerable attention due to their neuroprotective properties and multitargeted mechanisms of action against pathways implicated in AD. However, their clinical application is limited by poor Blood-Brain Barrier (BBB) permeability, low bioavailability, and inadequate solubility. Nanotechnology offers a promising approach for brain-targeted drug delivery by enhancing the therapeutic efficacy of phytoconstituents through advanced nanocarrier systems. This review explores the synergistic potential of phytoconstituents and nanocarriers for the management of AD, aiming to improve therapeutic outcomes and overcome existing limitations. It further highlights the integration of medicinal plant-based compounds with nanotechnology as a novel strategy for AD treatment. The combination of nanocarriers and phytoconstituents may facilitate enhanced BBB penetration and improved neuroprotection. Notably, nanomedicine- based approaches, including phytoconstituent-loaded nanoparticles and liposomes, demonstrate significant potential to overcome delivery barriers and enable efficient drug transport to the brain.",

We present scImmuneCo, a comprehensive resource of immune cell-specific co-expression modules derived from single-cell RNA sequencing across 17 immunological conditions and 1.78 million cells. Using a modified graph-based framework, we constructed 873 robust modules spanning 7 major immune cell types, providing stable, cell-type-specific interaction networks for functional inference. scImmuneCo resolves complex biology at cellular resolution. We identify 20 interferon-related modules that reveal both conserved and cell-type-specific regulatory programs, clarifying disease-dependent differences that are invisible to pathway tools treating interferon signaling as a unitary process. We also uncover age-associated CD8+ T cell programs, capturing state transitions from naive to effector/memory cells and exposing a progressive imbalance in translation and cytotoxicity with age. Together, these results demonstrate the power of high-resolution, data-driven functional inference to link gene groups to biological roles and disease processes. To support broad application, we provide an R package (https://github.com/FrankQYW/scImmuneCo_R) for module-based analysis of both single-cell and bulk transcriptomic data, along with an interactive web portal (http://www.scimmuneco.site/) for visualization and gene-module exploration. scImmuneCo offers a scalable and interpretable framework for dissecting immune mechanisms and identifying disease-relevant transcriptional programs with cellular resolution.",
"42412805": "ID: 42412805\nTitle: Amaranth: enhanced single-cell transcript assembly via discriminative modelling of UMI reads and internal reads.\nAbstract: Single-cell RNA sequencing (scRNA-seq) has transformed transcriptome profiling at cellular resolution, yet accurate reconstruction of full-length transcripts for individual cells remains a central challenge. Emerging scRNA-seq protocols can produce reads that span entire transcripts, enabling isoform-level expression analysis. For example, Smart-seq protocols combine unique molecular identifier (UMI)-linked reads that index and stitch together multiple reads from the same molecule, with internal reads filling coverage gaps. We demonstrate that these read types exhibit markedly different biological and statistical properties in strandness, 5'/3' coverage bias, and genomic locality. Existing assemblers fail to leverage these distinctions, yielding suboptimal assembly. We developed Amaranth, a novel single-cell assembler that discriminatively models UMI and internal reads. Amaranth implements heuristics specifically designed to address the distinct biases of UMI-linked and internal reads, enabling accurate strandness assignment for internal reads, reliable splicing graph refinement, and precise transcript start site determination. We also developed Amaranth-meta, which integrates information across cells to enhance individual cell assemblies. Benchmarked on Smart-seq3 datasets from human HEK293T and mouse fibroblast cells, Amaranth outperformed other state-of-the-art assemblers in assembling individual cells and in meta-assembly. Amaranth advances isoform-level analysis in single-cell transcriptomics, facilitating detailed studies at cellular resolution.

"42412816": "ID: 42412816\nTitle: Diffusion-based representation integration for foundation models improves spatial transcriptomics analysis.\nAbstract: We propose DRIFT, a framework that integrates spatial context into the input representations for foundation models by leveraging diffusion on spatial graphs derived from spatial transcriptomics (ST) data. ST captures gene expression profiles while preserving spatial context, enabling downstream analysis tasks such as cell-type annotation, clustering, and cross-sample alignment. However, due to its emerging nature, there are very few foundation models that can utilize ST data to generate embeddings generalizable across multiple tasks. Meanwhile, well-documented foundational models trained on large-scale single-cell gene expression (scRNA-seq) data have demonstrated generalizable performance across scRNA-seq assays, tissues, and tasks; however, they do not leverage the spatial information in ST data. We use heat kernel diffusion to propagate embeddings across spatial neighborhoods, incorporating the local neighborhood context of the ST data while preserving the transcriptomic representations learned by state-of-the-art single-cell foundation models. We systematically benchmark five foundational models (both scRNA-seq and ST-based) across key ST tasks such as annotation, alignment, and clustering, ensuring a comprehensive evaluation of our proposed framework. Our results show that DRIFT significantly improves the performance of existing foundational models on ST data over specialized state-of-the-art methods. Overall, DRIFT is an effective, accessible, and generalizable framework that bridges the gap toward universal models for modeling spatial transcriptomics.

Meanwhile, the rich local and global spatial topology inherent in spatial data are crucial for accurate biological interpretation but remain underutilized by existing methods. Here, we propose R4ST, an end-to-end framework designed to complete ST data. R4ST leverages scRNA-seq data as a reference and employs dual learning channels based on graph inductive and transductive modeling to capture complementary spatial topology information in ST data, enabling accurate reconstruction of missing gene expression. Extensive evaluations across multiple datasets from different platforms demonstrate that R4ST enables accurate recovery of large-scale gene expression profiles from a small subset of measured genes, uncovers novel spatial patterns associated with rare cell types, and substantially enhances the biological interpretability of ST data. https://github.com/zpliulab/R4ST.",

Most assays typically profile only one modality from a tissue slice, raising the question of how to align spatial data from heterogeneous feature spaces. While multiple approaches have been developed for multi-modal integration of single-cell datasets, few existing techniques perform spatial alignment across arbitrary modalities incorporating both spatial and feature information. We introduce Manifold Gromov-Wasserstein (MGW), a metric-learning framework that exploits the product structure of spatial multiomics to infer modality-specific Riemannian pull-back metrics with neural fields. MGW aligns Riemannian distances induced by these metrics via Gromov-Wasserstein optimal transport, yielding a hyperparameter-free cost across arbitrary modalities sharing a spatial base. The formulation enjoys theoretical invariances-including orthogonal transformations of the spatial and feature domains as well as global feature scalings. We demonstrate the advantages of MGW on multiple alignment tasks, including Stereo-Seq spatiotemporal transcriptomics of mouse embryo, Xenium and Visium spatial transcriptomics of colorectal cancer, and spatial metabolomics-transcriptomics from human striatum and kidney cancer. MGW recovers biologically meaningful correspondences and spatially coherent tissue structures, outperforming existing OT and non-OT based multi-modal baselines.

Although single-cell transcriptomics offers high-resolution profiling, translating these insights into clinical drug response prediction remains challenging. Recently, transfer learning approaches have attempted to predict patient drug response by leveraging pre-clinical data. However, these approaches operate at the bulk level, often masking the cellular heterogeneity essential for prediction. In this study, we propose scTAPE, a disentangled transfer learning framework to predict patient drug response using tumor single-cell transcriptomics. scTAPE follows a pre-training and fine-tuning paradigm. During the pre-training stage, scTAPE uses a disentangled learning strategy to extract intrinsic pharmacological signals masked by confounding factors from the matched bulk and single-cell expression profiles. Subsequently, a supervised drug response model is trained on labeled cell-line data to fine-tune the aligned common embedding, thereby achieving cross-domain generalization to unseen datasets. Experimental results demonstrate that scTAPE successfully predicts drug response across cell-line datasets and two independent clinical cohorts, outperforming state-of-the-art single-cell-based predictors. Furthermore, by analyzing tumor cell subpopulations, scTAPE not only predicts patient drug response to both single and combination treatments but also identifies potential therapeutic agents targeting drug-resistant subpopulations.

Their applications have rapidly expanded with several tissue targeting formulations in early-phase clinical trials. Beyond small molecular drugs, LNDDSs are increasingly employed for delivery of nucleic acid therapeutics, such as ribonucleic acid (RNA) based vaccines and immunomodulators. Recent advances in nanomaterials have enabled LNDDSs not only to transport therapeutic agents across systemic biological barriers but also to selectively destabilize plasma and organelle membranes, such as endosomes and mitochondria, addressing a wide range of diseases. This review systematically examines design strategies for LNDDSs that traverse key biological barriers focusing on the blood-tumor barrier, blood-brain barrier, and lymphatic transport barriers. We further explore approaches including fusogenic, pH-, redox- and, enzyme-sensitive and externally (ultrasound and thermal) triggered LNDDSs to facilitate internalization and membrane destabilization for specific organelle-targeting.

This systematic review aimed to investigate the efficacy and tolerability of virotherapy treatment for recurrent and progressive glioblastoma patients. We also examined recent progress in preclinical and clinical trials, and future perspectives. We developed a search strategy using Medical Subject Headings (MeSH) terms and keywords. Inclusion criteria were English language published and ongoing clinical trials that involved patients undergoing virotherapy for glioblastoma. We searched through PubMed, Embase, Ovid, Scopus, Cochrane databases and https://Clinicaltrials.gov from inception until May 9th, 2025. Two independent reviewers screened records, extracted data, and assessed risk of bias (ROB2). No meta-analysis was performed due to heterogeneity. PROSPERO CRD420250636791. Of 975 records screened, 43 studies (24 published, 19 ongoing) enrolled 462 virotherapy patients. Most common adverse events: headache (n=145), fatigue (n=83) and fever (n=78). Risk of bias was moderate to serious in most studies. We encountered several limitations, including high heterogeneity, reporting inconsistencies, and small sample sizes. Most patients experienced disease stabilization. However, objective response and complete remission occurred infrequently. A small proportion of patients achieved long-term survival, suggesting that virotherapy could be effective in specific subgroups. While oncolytic virus therapy is generally tolerated, neurotoxicity remains the most significant risk. Adverse effects were mostly Grade 1-2. Some trials (notably with HSV-1 or NDV) had severe events. Symptoms were often transient and manageable but need closely monitoring. However, the observed heterogeneity, limited data standardisation, and lack of randomized controlled trials, besides tumor heterogeneity, antiviral immunity and immunosuppressive microenvironment, necessitate further research to identify predictive biomarkers and optimize therapeutic protocols.

Rhizome differentiation is a common developmental feature in perennial medicinal plants, yet its association with secondary metabolism and rhizosphere microbial assembly remains poorly understood. Here, we investigated the functional divergence between main rhizome (DH) and lateral rhizome (DC) of Rheum officinale Baill. using integrated metabolomic and transcriptomic analyses, quantitative real-time PCR (qRT-PCR) validation, and rhizosphere microbiome analyses. Metabolomic profiling revealed distinct patterns in anthraquinone allocation among rhizome types. DC exhibited a higher relative abundance of total detected anthraquinones and was enriched in both free anthraquinones (e.g., rhein) and selected glycosylated anthraquinones (e.g., chrysophanol 1-tetraglucoside), whereas DH preferentially accumulated other glycosylated metabolites such as cassiaside B2. Transcriptomic analysis identified 484 differentially expressed genes (DEGs) associated with these metabolic differences. Genes involved in anthraquinone biosynthesis and modification, including polyketide synthase (PKS), cytochrome P450 (CYP450), O-methyltransferase (OMT), and UDP-glycosyltransferase (UGT) family members, exhibited differential expression patterns associated with rhizome type, which were further validated by qRT-PCR. Although overall rhizosphere microbial diversity showed no significant differences between rhizome types, specific taxonomic shifts were observed, with Stenotrophomonas enriched in DC and Bacilli enriched in DH. Integrated analysis indicated correlation patterns among rhizome architecture, anthraquinone metabolism, transcriptional variation, and rhizosphere microbial composition. However, the directionality and underlying mechanisms of these relationships remain unresolved and warrant further mechanistic investigation.

We analyzed predefined ASD risk-gene sets across BrainSpan developmental transcriptomics, three adult cortical bulk cohorts, fetal and adult single-cell resources, composition-aware bulk models, SynGO and Reactome annotations, matched-random controls, correlation-aware gene-set tests, and STRING physical-interaction networks. The broad SFARI gene set showed the strongest adult cortex ASD-control meta-analytic reduction, driven mainly by its SynGO-annotated synaptic component. This adult signal remained significant in Gandal2022 after donor-aware modeling, donor-level aggregation, mixed-effects modeling, covariate sensitivity analyses, outlier checks, and drop-one-reference composition adjustment. Size-matched gene-level resampling indicated that the signal was not explained by gene-set size alone, whereas expression-matched controls supported a more conservative interpretation involving expression-level background properties. In contrast, the mid-prenatal top-20% SFARI subset localized more strongly to fetal progenitor-to-neurogenic states and chromatin-regulatory Reactome terms but did not show a stable adult cortical ASD-control effect. These results define an adult synaptic ASD-associated layer and a mid-prenatal developmental-regulatory layer within predefined ASD risk-gene sets.",

However, the shared pathogenic mechanisms remain unclear. This study applied integrated bioinformatics to identify shared candidate markers for MDD and vitiligo. Public transcriptomic datasets from the GEO database were analyzed for differential expression. Protein-protein interaction (PPI) networks were constructed using the STRING database. Shared differentially expressed genes (DEGs) underwent GO and KEGG functional enrichment analyses. Three machine-learning algorithms were applied to select candidate biomarker genes. Additionally, immune infiltration analysis was quantified through ssGSEA and a TF-miRNA network was constructed via NetworkAnalyst platform. Single-gene GSEA further explored pathways linked to the biomarker in both diseases. Differential expression analysis and PPI network construction suggest the involvement of 14 hub genes potentially linked to both MDD and vitiligo. Functional enrichment analyses indicate their putative roles in immune processes and inflammatory responses. Machine learning further prioritized three key genes: EXOSC7, KLRG1, and MAPK14. Immune infiltration analysis revealed distinct patterns of inferred immune enrichment signatures, and the TF-miRNA network highlighted the complexity of the regulatory landscape. Preliminary validation suggests MAPK14 as a potential candidate gene warranting further investigation in MDD and vitiligo. This study provides preliminary evidence suggesting that immune dysregulation and inflammatory activation may be interconnected in MDD and vitiligo. MAPK14 represents a potential candidate marker for their comorbidity. These findings primarily serve to generate hypotheses regarding shared mechanisms and prioritize targets for subsequent experimental validation.",

This species has an extended adult dormancy period lasting approximately 9 months. This period encompasses summer estivation and winter diapause in mountainous dormancy areas. Despite its economic importance and unusual dormancy biology, the molecular basis of seasonal dormancy in A. rostrata remains unexplored. Here, we combined RNA-seq, proteomics, and lipid content measurements to provide the first molecular insights into estivation and winter diapause responses in the fat body of the wheat stink bug. Transcriptomic enrichment analyses suggested that genes associated with protein synthesis, cytoplasmic translation, and ribosomal activity were enriched during estivation, whereas pathways related to catabolic processes, fatty acid metabolism, and pathogen response were associated with winter diapause. Complementary proteomic analyses identified mitochondrial and chitinase-like proteins with higher abundance during estivation, while proteins related to energy metabolism, including acyl-CoA dehydrogenases, were more abundant during winter diapause. Lipid measurements indicated significantly lower lipid reserves in post-diapause individuals compared to actively feeding adults, consistent with the utilization of lipid stores during dormancy and/or the transition to post-dormancy activity. Overall, this study provides the first transcriptomic and proteomic resource for A. rostrata and offers initial molecular insights into the physiological signatures associated with seasonal dormancy in this economically important pest."
