ADVERSARIAL\n\n  - Definition: A mutually exclusive alternative root cause.\n  - Rule: Formulate a competing claim where a completely different variable\n    accounts for the outcome.\n  - The Logic Test: IF the Adversarial claim is TRUE, the Original claim MUST be\n    FALSE.

ID: 12345 - Application: The text discusses ... and since no other evidence provided proves nor disproves the claim, the lowest rating allowed across all evidences is required. ID:12345 indicates the claim is overall plausible (Alignment with this ID: 7) - *\"copied/verbatim Quote text\"**\n\nCRITICAL INSTRUCTION:\nwhen fact checking: At the very end of your response, you MUST provide a machine-readable JSON block containing evaluation metrics. \nIt MUST be enclosed exactly between ###JSON_START### and ###JSON_END###. Ensure the JSON is valid. \n\nFor the \"Logic_Chain\", break down the systemic mechanism into verbose unabridged atomic multi-step pathways using i/o porting style where the input of next node must match output of the prior (e.g., A -> B, B->C, C->D). Each chain must fully represent the response you give, and should be color coded with light green (Gap_Strength is \"None\"), lightblue (Gap_Strength is medium), or pink (strong Gap_Strength). Logic_Chain MUST be a JSON array of objects. Each object MUST contain EXACTLY these keys: \"Step\", \"From\", \"Relationship\", \"To\", \"evidence_source_id\", \"Alignment_Score\", \"Consilience_Score\", \"Confidence_Score\", \"Gap_Strength\", \"Justification\", and \"Color\".

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

Exosomes have emerged as key mediators of central nervous system communication and are increasingly central to the biology of neurodegeneration. These nanoscale vesicles transport proteins, lipids, and nucleic acids across cellular and anatomical barriers, influencing synaptic function, immune signaling, and metabolic homeostasis. Under pathological conditions, exosomes facilitate the spread of misfolded proteins such as amyloid-\u03b2, p-tau, \u03b1-synuclein, and TDP-43, thereby accelerating network-level degeneration. At the same time, their cargo exhibits disease-specific molecular signatures detectable in peripheral biofluids, supporting their development as minimally invasive biomarkers for early diagnosis and longitudinal monitoring. Advances in exosome engineering further underscore their potential as therapeutic delivery vehicles capable of crossing the blood-brain barrier and targeting pathogenic pathways with RNA-based therapeutics, proteins, or gene-editing systems. Together, these findings position exosomes as pivotal contributors to both the mechanistic progression and translational targeting of neurodegenerative diseases."

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

Although autophagy dysfunction, glial senescence, and inflammasome activation are well-established contributors to progressive neurodegeneration, these processes are often analysed independently or through pairwise interactions, leaving their collective contribution to persistent neuroinflammation and disease progression insufficiently defined. Here, we synthesise emerging evidence supporting an integrated 'Autophagy-Senescence-Inflammasome (ASI) axis', in which reciprocal interactions among impaired autophagy, senescent glia, and inflammasome signalling establish a self-sustaining cycle of neuroinflammation. We discuss how defective autophagy promotes mitochondrial dysfunction, oxidative stress, and danger signalling, while senescent astrocytes and microglia amplify inflammatory responses through the senescence-associated secretory phenotype (SASP). These intertwined processes converge on chronic inflammasome activation, with mitochondrial dysfunction emerging as a central mechanistic hub. Evidence across Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, stroke, and chronic neuropathic pain highlight the broad relevance of this pathological network. We further analyse current therapeutic strategies targeting autophagy, senescence, and inflammasome pathways, emphasising the limitations of single-target approaches and the potential of multi-target interventions. By integrating these processes into a unified framework, this review provides new insights into the possible molecular mechanisms underlying neuroinflammaging and identifies the 'ASI axis' as a promising target for neurodegenerative disease-modifying therapies."

This review aims to explore the use of blood-based NfL as an endpoint in clinical trials of neurodegenerative conditions. A database search of MEDLINE and EMBASE was conducted to identify interventional clinical trials and/or related post hoc analyses for neurodegenerative diseases, published between 2013 and 2024 that reported the use of serum or plasma NfL as an endpoint. Additional studies from reference lists of included trials were manually considered for inclusion where relevant. Data were charted descriptively by disease type and summarised. 49 studies were included, 29 in multiple sclerosis (MS), eight in amyotrophic lateral sclerosis (ALS), six in Alzheimer's disease (AD), and six in other diseases. Across studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response. However, several studies demonstrated a lack of concordance between change in NfL and in clinical outcomes, some of which may be related to the non-disease-modifying mechanisms of the interventions studied. This necessitates careful consideration when applying blood-based NfL as a biomarker endpoint for studies involving such interventions. Blood NfL is a promising biomarker with potential utility as a surrogate endpoint in neurological clinical trials, particularly for diseases with active axonal injury. Further validation, particularly around disease- and intervention-specific interpretation, is needed before blood NfL can be incorporated more routinely as a clinical endpoint."

While Secretory leukocyte protease inhibitor (SLPI) is known for its immunomodulatory properties, its specific role in ALS pathogenesis has not been fully established. This study aimed to characterize the expression patterns and functional significance of SLPI in ALS models. The study utilized SOD1G93A mice to analyze the spatiotemporal dynamics of SLPI expression in the gastrocnemius muscle, lumbar spinal cord, and serum across different disease stages. In vitro functional assays were conducted using siRNA-mediated knockdown of SLPI in BV2 (microglia), MA (astrocytes), and NSC-34 (motor neurons) cell lines. Additionally, recombinant SLPI protein was applied to LPS-stimulated BV2 cells to investigate its effect on the TLR4/ NF-\u03baB signaling pathway. In SOD1G93A mice, SLPI was significantly upregulated in the gastrocnemius muscle from the pre-symptomatic stage (60 days) through the late stage (130 days). In the lumbar spinal cord, SLPI showed a transient initial increase but declined sharply by the end-stage; a similar significant reduction was observed in late-stage serum levels. In vitro, SLPI knockdown exacerbated pro-inflammatory cytokine production in all three cell types and impaired the antioxidant capacity of NSC-34 motor neurons. Mechanistically, recombinant SLPI attenuated inflammation in BV2 cells by modulating the TLR4/NF-\u03baB pathway. The dynamic changes in SLPI levels suggest its potential relevance as a candidate molecule for disease staging. Meanwhile, its protective effects in regulating inflammation suggest that it could be a promising therapeutic candidate for mitigating ALS-associated neuroinflammation."

The transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) plays pivotal roles in the cellular defense system against oxidative and xenobiotic stress, making NRF2 activation a promising therapeutic target for ocular neurodegenerative disorders. Covalent NRF2 activators have been extensively studied in clinical trials, leading to the approval of two drugs. However, no non-covalent NRF2- Kelch-like ECH-associated protein 1 (KEAP1) protein-protein interaction (PPI) inhibitors are currently in clinical development, despite their potential for selective and reversible KEAP1 inhibition with fewer side effects. In this study, to develop high potency compounds with suitable properties for an eye drop preparation, we modified the structure of known NRF2-KEAP1 PPI inhibitors. The newly identified compound, SLOS-1811-06 tR1, exhibited neuroprotective effects at concentrations \u22650.01\u202fnM in a hypoxia-induced neurodegeneration model using human-induced pluripotent stem cell (hiPSC)-derived RGCs. It showed high aqueous solubility (21.04\u202f\u00b1\u202f0.08\u202fmg/mL), enabling easy formulation as an eye drop. One hour after a single topical dose of a 0.5% SLOS-1811-06 tR1 solution in rabbits, its concentration in the posterior retina/choroid was 4.4\u202f\u00b1\u202f2.7\u202fnM, exceeding the effective level observed in vitro. These findings highlight the potential of SLOS-1811-06 tR1 as a promising topical drug candidate for treating oxidative stress-related glaucoma."

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

This chapter elucidates their utility in detecting biomarkers for the diagnosis and monitoring of progression and response to treatment in different prevalent neurologic conditions. The retina, an extension of the central nervous system, presents a unique opportunity for monitoring brain pathology due to its accessibility. Through highly resolved scans of the retina and optic nerve, OCT and OCTA facilitate the identification of subtle clinical changes occurring during neuroinflammatory, neurodegenerative, and ischemic processes in disorders like multiple sclerosis, Alzheimer and Parkinson disease, anterior ischemic optic neuropathies, and papilledema. Peripapillary nerve fiber layer and macular internal retinal layer thickness on OCT, and vessel density in the superficial retina on OCTA seem to be the most sensitive parameters in detecting axonal injury and neurodegeneration. These metrics hold promise as surrogate markers for cerebral alterations. While OCT and OCTA show considerable potential, continued research is necessary to validate their reliability and clinical significance, considering potential confounding factors such as concurrent ophthalmic pathologies. Nonetheless, these advancements represent significant progress toward enhancing the diagnosis, management, and prediction of outcomes in various neuro-ophthalmic disorders."

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

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

The ubiquitin-proteasome system (UPS), a major pathway for selective intracellular protein degradation, is essential for maintaining neuronal protein homeostasis. Proteasome dysfunction has been implicated in several major neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and Huntington's disease (HD), although its extent and mechanisms vary across disease contexts. In this review, we examine current evidence for proteasome dysfunction in neurodegeneration and discuss how disease-associated proteins impair proteasome function through direct inhibition, defective substrate processing, and sequestration into protein aggregates. We also address the contribution of oxidative stress, neuroinflammation, and aging to proteasome dysregulation. Finally, we highlight emerging therapeutic strategies aimed at restoring proteasome function, including pharmacological activation, modulation of proteasome assembly and stability, and targeted protein degradation approaches. Understanding the context-dependent nature of proteasome dysfunction will be important for developing effective proteostasis-based therapies."

Neurons are particularly vulnerable to these processes due to their post-mitotic nature and complex architecture. Autophagy and the endolysosomal system constitute the primary degradative pathways responsible for maintaining neuronal homeostasis. However, increasing evidence indicates that their effective function critically depends on coordination with the endosomal sorting complexes required for transport (ESCRT). Beyond their canonical role in multivesicular body biogenesis and membrane scission, ESCRT components are now recognized as essential regulators of autophagosome closure, amphisome formation, autophagosome-lysosome fusion, and endolysosomal membrane repair. Disruption of this ESCRT-autophagy interface has emerged as a common pathological feature across major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis/frontotemporal dementia. This review synthesizes evidence from genetic, biochemical, and neuropathological studies to highlight shared molecular nodes, such as ESCRT-III components, the VPS4 ATPase, the adaptor protein ALIX, and late endosomal regulators, including Rab7, that couple membrane remodeling to autophagic flux. Failure of these regulatory checkpoints destabilizes endolysosomal integrity, arrests autophagic maturation, and promotes the accumulation of toxic protein species, thereby driving progressive neuronal degeneration. By framing neurodegeneration through the lens of ESCRT-autophagy coupling failure, this review provides a unified mechanistic perspective that links diverse pathogenic proteins to shared cellular vulnerabilities and identifies ESCRT-mediated membrane dynamics as a critical determinant of neuronal survival."

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

However, there is limited understanding of how HERV-K is trafficked in peripheral biofluids, and the role of exosomes, nano-sized extracellular vesicles, in this process remains largely unexplored. Exosomes offer a stable and cell-specific cargo reservoir that may reflect central pathogenic processes and serve as a minimally invasive biomarker source. In this study, we isolated plasma-derived exosomes from ALS patients (n\u2009=\u200921) and healthy controls (n\u2009=\u200916), and quantified exosomal HERV-K gag, env, and pol transcript levels using SYBR Green qPCR with RNase treatment and normalization to both traditional and exosome-enriched reference genes. HERV-K pol expression was significantly elevated in ALS, with fold-changes ranging from 1.59 to 1.85 (P\u2009=\u20090.037-0.051). env and gag also showed increased expression, though with greater variability. Normalization to the exosome-specific gene SOD2 provided the most consistent signal. These findings suggest that exosomal HERV-K transcripts, particularly pol, could serve as accessible biomarkers for patient stratification and treatment monitoring in HERV-K-targeted ALS trials. This work establishes proof-of-concept for using exosomal cargo to track endogenous retroviral activity in neurodegeneration and supports further investigation of liquid biopsy approaches in ALS precision medicine."

Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease."

We integrated clinical data from the National Health and Nutrition Examination Survey (NHANES) with an independent hospital cohort (Nantong First People's Hospital). A multi-stage feature selection pipeline (Boruta algorithm and LASSO regression) was utilized to identify core predictors. Eight ML algorithms were benchmarked. To transcend conventional \"black-box\" predictions, we coupled SHAP (SHapley Additive exPlanations) for personalized interpretability with a Bayesian Network Directed Acyclic Graph (DAG) to map the probabilistic dependency structure among the selected systemic biomarkers. The LightGBM algorithm outperformed other classifiers, yielding a robust external validation AUC of 0.841 (95% CI: 0.809-0.862). Fourteen key routine predictors were identified, spanning glycemic control, renal function, and lipid metabolism. Crucially, probabilistic dependency structure via the Bayesian Network revealed a hierarchical pathogenetic topology: rather than parallel associations, latent renal impairment markers (urine protein, BUN, and urine creatinine) and chronic glycemic toxicity (HbA1c) emerged as direct upstream dependency drivers of DR. This structural evidence suggests a probabilistic dependency consistent with the 'kidney-eye crosstalk' hypothesis. We successfully deployed a high-performing, non-invasive LightGBM model for early DR screening. By integrating predictive ML with probabilistic dependency structure, this framework not only delivers an accessible, web-based clinical decision support system (CDSS) for resource-constrained settings but also provides preliminary insights into the potential systemic microvascular interplay driving diabetic retinopathy."

Multidomain lifestyle interventions might delay cognitive decline, but populations from Latin America remain under-represented in dementia prevention trials. We aimed to investigate the feasibility of a culturally adapted, multidomain, systematic lifestyle intervention and investigate its effects on global cognitive function in at-risk older adults (aged 60-77 years). The LatAm-FINGERS Initiative for Cognitive Change (hereafter referred to as LatAm-FINGERS) was a single-blind, multicentre, randomised clinical trial conducted in 11 Latin American countries (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Peru, and Uruguay). Individuals aged 60-77 years with high risk of dementia (cardiovascular risk factors, ageing, and dementia risk score \u22656), and suboptimal cognitive performance were randomly assigned (1:1) to receive either a 2-year systematic lifestyle intervention (SLI group) or a flexible lifestyle intervention (FLI group). Randomisation was stratified by the study centre to ensure balance and implemented using permuted blocks of eight. Participants and intervention staff were not masked to group assignment, but individuals who assessed outcomes were masked throughout the trial. The SLI provided structured multidomain lifestyle interventions with supervised support and monitoring; FLI offered health advice. Primary outcomes were trial feasibility (evaluated using selected RE-AIM measures: Reach, Implementation, and Maintenance) and the intervention's effects on global cognitive composite trajectories over 2 years (change in the global cognitive composite score over 2 years). This trial is registered at ClinicalTrials.gov (NCT06492967) and has been completed. Participants were enrolled between Oct 27, 2021, and July 7, 2023; the last participant completed follow-up on Nov 7, 2025. Among 1719 assessed, 1065 participants included in the analytic sample were randomly assigned to the SLI group (n=539) or the FLI group (n=526). Mean age was 67\u00b75 years (SD 4\u00b77), 795 (75%) of 1065 participants were women, and 270 (25%) were men. Self-reported race and ethnicity were: 624 (59%) Mestizo, 288 (27%) White, 72 (7%) Mulatto, 25 (2%) Mixed or other, 18 (2%) Black, 14 (1%) Indigenous, and 24 (2%) did not report race or ethnicity. 877 (82\u00b73%) of 1065 completed the 2-year follow-up. Recruitment effectiveness (Reach) was 62\u00b70%; mean adherence to the SLI group (Implementation) was 71\u00b76% over the entire trial; and frequencies of complete cognitive outcomes data (Maintenance) were 87\u00b79% at 6 months, 85\u00b73% at 12 months, 81\u00b74% at 18 months, and 84\u00b78% at 24 months in the SLI group compared with 86\u00b73% at 6 months, 78\u00b79% at 12 months, 73\u00b74% at 18 months, and 79\u00b78% at 24 months in the FLI group. Dropouts were higher in the FLI group than in the SLI group (20\u00b72% vs 15\u00b72%; p=0\u00b7042). Global cognitive composite scores increased over time in both groups, with a mean annual change of 0\u00b731 SD (95% CI 0\u00b728-0\u00b734) per year in the SLI group and 0\u00b720 SD (0\u00b717-0\u00b723) per year in the FLI group (mean between-group difference of 0\u00b711 SD per year [0\u00b706-0\u00b715; p<0\u00b70001]). Overall, 478 adverse events were reported (412 in the SLI group and 66 in the FLI group). The most common adverse events were musculoskeletal symptoms (113 [21%] in the SLI group, 13 [2%] in the FLI group), upper respiratory infections (50 [9%] in the SLI group, one [<1%] in the FLI group), and COVID-19 infection (31 [6%] events in the SLI group). Serious adverse events occurred in 50 (9%) participants in the SLI group and 24 (5%) participants in the FLI group; none were related to the intervention. There were eight deaths (three in the SLI group and five in the FLI group), and none were related to the intervention. A culturally adapted multidomain lifestyle intervention was feasible across Latin America and resulted in greater cognitive improvements than a flexible health-advice intervention in older adults at risk of cognitive decline. These findings extend the evidence base for multidomain lifestyle interventions to populations historically under-represented in dementia research, supporting their feasibility and scalability as strategies to reduce cognitive decline risk amid the rapidly growing burden of dementia in low-income and middle-income countries.

Although autophagy dysfunction, glial senescence, and inflammasome activation are well-established contributors to progressive neurodegeneration, these processes are often analysed independently or through pairwise interactions, leaving their collective contribution to persistent neuroinflammation and disease progression insufficiently defined. Here, we synthesise emerging evidence supporting an integrated 'Autophagy-Senescence-Inflammasome (ASI) axis', in which reciprocal interactions among impaired autophagy, senescent glia, and inflammasome signalling establish a self-sustaining cycle of neuroinflammation. We discuss how defective autophagy promotes mitochondrial dysfunction, oxidative stress, and danger signalling, while senescent astrocytes and microglia amplify inflammatory responses through the senescence-associated secretory phenotype (SASP). These intertwined processes converge on chronic inflammasome activation, with mitochondrial dysfunction emerging as a central mechanistic hub. Evidence across Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, stroke, and chronic neuropathic pain highlight the broad relevance of this pathological network. We further analyse current therapeutic strategies targeting autophagy, senescence, and inflammasome pathways, emphasising the limitations of single-target approaches and the potential of multi-target interventions. By integrating these processes into a unified framework, this review provides new insights into the possible molecular mechanisms underlying neuroinflammaging and identifies the 'ASI axis' as a promising target for neurodegenerative disease-modifying therapies."

Data were charted descriptively by disease type and summarised. 49 studies were included, 29 in multiple sclerosis (MS), eight in amyotrophic lateral sclerosis (ALS), six in Alzheimer's disease (AD), and six in other diseases. Across studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response. However, several studies demonstrated a lack of concordance between change in NfL and in clinical outcomes, some of which may be related to the non-disease-modifying mechanisms of the interventions studied. This necessitates careful consideration when applying blood-based NfL as a biomarker endpoint for studies involving such interventions. Blood NfL is a promising biomarker with potential utility as a surrogate endpoint in neurological clinical trials, particularly for diseases with active axonal injury. Further validation, particularly around disease- and intervention-specific interpretation, is needed before blood NfL can be incorporated more routinely as a clinical endpoint."

While Secretory leukocyte protease inhibitor (SLPI) is known for its immunomodulatory properties, its specific role in ALS pathogenesis has not been fully established. This study aimed to characterize the expression patterns and functional significance of SLPI in ALS models. The study utilized SOD1G93A mice to analyze the spatiotemporal dynamics of SLPI expression in the gastrocnemius muscle, lumbar spinal cord, and serum across different disease stages. In vitro functional assays were conducted using siRNA-mediated knockdown of SLPI in BV2 (microglia), MA (astrocytes), and NSC-34 (motor neurons) cell lines. Additionally, recombinant SLPI protein was applied to LPS-stimulated BV2 cells to investigate its effect on the TLR4/ NF-\u03baB signaling pathway. In SOD1G93A mice, SLPI was significantly upregulated in the gastrocnemius muscle from the pre-symptomatic stage (60 days) through the late stage (130 days). In the lumbar spinal cord, SLPI showed a transient initial increase but declined sharply by the end-stage; a similar significant reduction was observed in late-stage serum levels. In vitro, SLPI knockdown exacerbated pro-inflammatory cytokine production in all three cell types and impaired the antioxidant capacity of NSC-34 motor neurons. Mechanistically, recombinant SLPI attenuated inflammation in BV2 cells by modulating the TLR4/NF-\u03baB pathway. The dynamic changes in SLPI levels suggest its potential relevance as a candidate molecule for disease staging. Meanwhile, its protective effects in regulating inflammation suggest that it could be a promising therapeutic candidate for mitigating ALS-associated neuroinflammation."

The transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) plays pivotal roles in the cellular defense system against oxidative and xenobiotic stress, making NRF2 activation a promising therapeutic target for ocular neurodegenerative disorders. Covalent NRF2 activators have been extensively studied in clinical trials, leading to the approval of two drugs. However, no non-covalent NRF2- Kelch-like ECH-associated protein 1 (KEAP1) protein-protein interaction (PPI) inhibitors are currently in clinical development, despite their potential for selective and reversible KEAP1 inhibition with fewer side effects. In this study, to develop high potency compounds with suitable properties for an eye drop preparation, we modified the structure of known NRF2-KEAP1 PPI inhibitors. The newly identified compound, SLOS-1811-06 tR1, exhibited neuroprotective effects at concentrations \u22650.01\u202fnM in a hypoxia-induced neurodegeneration model using human-induced pluripotent stem cell (hiPSC)-derived RGCs.

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

This chapter elucidates their utility in detecting biomarkers for the diagnosis and monitoring of progression and response to treatment in different prevalent neurologic conditions. The retina, an extension of the central nervous system, presents a unique opportunity for monitoring brain pathology due to its accessibility. Through highly resolved scans of the retina and optic nerve, OCT and OCTA facilitate the identification of subtle clinical changes occurring during neuroinflammatory, neurodegenerative, and ischemic processes in disorders like multiple sclerosis, Alzheimer and Parkinson disease, anterior ischemic optic neuropathies, and papilledema. Peripapillary nerve fiber layer and macular internal retinal layer thickness on OCT, and vessel density in the superficial retina on OCTA seem to be the most sensitive parameters in detecting axonal injury and neurodegeneration. These metrics hold promise as surrogate markers for cerebral alterations. While OCT and OCTA show considerable potential, continued research is necessary to validate their reliability and clinical significance, considering potential confounding factors such as concurrent ophthalmic pathologies. Nonetheless, these advancements represent significant progress toward enhancing the diagnosis, management, and prediction of outcomes in various neuro-ophthalmic disorders."

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

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

Neurons are particularly vulnerable to these processes due to their post-mitotic nature and complex architecture. Autophagy and the endolysosomal system constitute the primary degradative pathways responsible for maintaining neuronal homeostasis. However, increasing evidence indicates that their effective function critically depends on coordination with the endosomal sorting complexes required for transport (ESCRT). Beyond their canonical role in multivesicular body biogenesis and membrane scission, ESCRT components are now recognized as essential regulators of autophagosome closure, amphisome formation, autophagosome-lysosome fusion, and endolysosomal membrane repair. Disruption of this ESCRT-autophagy interface has emerged as a common pathological feature across major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis/frontotemporal dementia. This review synthesizes evidence from genetic, biochemical, and neuropathological studies to highlight shared molecular nodes, such as ESCRT-III components, the VPS4 ATPase, the adaptor protein ALIX, and late endosomal regulators, including Rab7, that couple membrane remodeling to autophagic flux. Failure of these regulatory checkpoints destabilizes endolysosomal integrity, arrests autophagic maturation, and promotes the accumulation of toxic protein species, thereby driving progressive neuronal degeneration. By framing neurodegeneration through the lens of ESCRT-autophagy coupling failure, this review provides a unified mechanistic perspective that links diverse pathogenic proteins to shared cellular vulnerabilities and identifies ESCRT-mediated membrane dynamics as a critical determinant of neuronal survival."

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

However, there is limited understanding of how HERV-K is trafficked in peripheral biofluids, and the role of exosomes, nano-sized extracellular vesicles, in this process remains largely unexplored. Exosomes offer a stable and cell-specific cargo reservoir that may reflect central pathogenic processes and serve as a minimally invasive biomarker source. In this study, we isolated plasma-derived exosomes from ALS patients (n\u2009=\u200921) and healthy controls (n\u2009=\u200916), and quantified exosomal HERV-K gag, env, and pol transcript levels using SYBR Green qPCR with RNase treatment and normalization to both traditional and exosome-enriched reference genes. HERV-K pol expression was significantly elevated in ALS, with fold-changes ranging from 1.59 to 1.85 (P\u2009=\u20090.037-0.051). env and gag also showed increased expression, though with greater variability. Normalization to the exosome-specific gene SOD2 provided the most consistent signal. These findings suggest that exosomal HERV-K transcripts, particularly pol, could serve as accessible biomarkers for patient stratification and treatment monitoring in HERV-K-targeted ALS trials. This work establishes proof-of-concept for using exosomal cargo to track endogenous retroviral activity in neurodegeneration and supports further investigation of liquid biopsy approaches in ALS precision medicine."

Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease."

We integrated clinical data from the National Health and Nutrition Examination Survey (NHANES) with an independent hospital cohort (Nantong First People's Hospital). A multi-stage feature selection pipeline (Boruta algorithm and LASSO regression) was utilized to identify core predictors. Eight ML algorithms were benchmarked. To transcend conventional \"black-box\" predictions, we coupled SHAP (SHapley Additive exPlanations) for personalized interpretability with a Bayesian Network Directed Acyclic Graph (DAG) to map the probabilistic dependency structure among the selected systemic biomarkers. The LightGBM algorithm outperformed other classifiers, yielding a robust external validation AUC of 0.841 (95% CI: 0.809-0.862).

Multidomain lifestyle interventions might delay cognitive decline, but populations from Latin America remain under-represented in dementia prevention trials. We aimed to investigate the feasibility of a culturally adapted, multidomain, systematic lifestyle intervention and investigate its effects on global cognitive function in at-risk older adults (aged 60-77 years). The LatAm-FINGERS Initiative for Cognitive Change (hereafter referred to as LatAm-FINGERS) was a single-blind, multicentre, randomised clinical trial conducted in 11 Latin American countries (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Peru, and Uruguay). Individuals aged 60-77 years with high risk of dementia (cardiovascular risk factors, ageing, and dementia risk score \u22656), and suboptimal cognitive performance were randomly assigned (1:1) to receive either a 2-year systematic lifestyle intervention (SLI group) or a flexible lifestyle intervention (FLI group). Randomisation was stratified by the study centre to ensure balance and implemented using permuted blocks of eight. Participants and intervention staff were not masked to group assignment, but individuals who assessed outcomes were masked throughout the trial. The SLI provided structured multidomain lifestyle interventions with supervised support and monitoring; FLI offered health advice.

Among 1719 assessed, 1065 participants included in the analytic sample were randomly assigned to the SLI group (n=539) or the FLI group (n=526). Mean age was 67\u00b75 years (SD 4\u00b77), 795 (75%) of 1065 participants were women, and 270 (25%) were men. Self-reported race and ethnicity were: 624 (59%) Mestizo, 288 (27%) White, 72 (7%) Mulatto, 25 (2%) Mixed or other, 18 (2%) Black, 14 (1%) Indigenous, and 24 (2%) did not report race or ethnicity. 877 (82\u00b73%) of 1065 completed the 2-year follow-up. Recruitment effectiveness (Reach) was 62\u00b70%; mean adherence to the SLI group (Implementation) was 71\u00b76% over the entire trial; and frequencies of complete cognitive outcomes data (Maintenance) were 87\u00b79% at 6 months, 85\u00b73% at 12 months, 81\u00b74% at 18 months, and 84\u00b78% at 24 months in the SLI group compared with 86\u00b73% at 6 months, 78\u00b79% at 12 months, 73\u00b74% at 18 months, and 79\u00b78% at 24 months in the FLI group. Dropouts were higher in the FLI group than in the SLI group (20\u00b72% vs 15\u00b72%; p=0\u00b7042). Global cognitive composite scores increased over time in both groups, with a mean annual change of 0\u00b731 SD (95% CI 0\u00b728-0\u00b734) per year in the SLI group and 0\u00b720 SD (0\u00b717-0\u00b723) per year in the FLI group (mean between-group difference of 0\u00b711 SD per year [0\u00b706-0\u00b715; p<0\u00b70001]). Overall, 478 adverse events were reported (412 in the SLI group and 66 in the FLI group). The most common adverse events were musculoskeletal symptoms (113 [21%] in the SLI group, 13 [2%] in the FLI group), upper respiratory infections (50 [9%] in the SLI group, one [<1%] in the FLI group), and COVID-19 infection (31 [6%] events in the SLI group). Serious adverse events occurred in 50 (9%) participants in the SLI group and 24 (5%) participants in the FLI group; none were related to the intervention. There were eight deaths (three in the SLI group and five in the FLI group), and none were related to the intervention. A culturally adapted multidomain lifestyle intervention was feasible across Latin America and resulted in greater cognitive improvements than a flexible health-advice intervention in older adults at risk of cognitive decline. These findings extend the evidence base for multidomain lifestyle interventions to populations historically under-represented in dementia research, supporting their feasibility and scalability as strategies to reduce cognitive decline risk amid the rapidly growing burden of dementia in low-income and middle-income countries.

Extracellular vesicles (EVs) have emerged as critical mediators of intercellular communication and are increasingly implicated in the pathogenesis and progression of diabetes. This review summarizes current knowledge on EV biology, including their classification, cellular sources, biogenesis, uptake mechanisms, and molecular cargo. We discuss the contribution of EV-associated microRNAs to immune dysregulation and \u03b2-cell damage in type 1 diabetes mellitus (T1DM), as well as the role of EVs in insulin resistance, metabolic signaling, and vascular dysfunction in type 2 diabetes mellitus (T2DM). Particular emphasis is placed on EV-mediated modulation of endothelial function, angiogenesis, and tissue repair, alongside their involvement in the impairment of insulin receptor integrity. We further explore how lifestyle factors may influence EV composition and function, highlighting their potential integration into preventive strategies. Finally, we evaluate the emerging therapeutic potential of EVs as biomarkers and delivery systems, while addressing current limitations and future directions. Collectively, EVs represent a promising frontier in understanding diabetes pathophysiology and developing innovative diagnostic and therapeutic approaches. Unlike previous reviews that examine EVs separately as biomarkers or therapeutic vehicles, this review integrates emerging evidence supporting EVs as mediators of systemic communication linking pancreatic islets, adipose tissue, immune cells, vascular endothelium, kidney, heart, and retina throughout diabetes progression.

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

Assessment of BCVA was done using Snellen charts, and subjective refraction was done to achieve a BCVA for distance and near. Measurement of intraocular pressure (IOP) was done with Goldman applanation tonometry. Stereoscopic fundus examination was performed using a 90D lens to assess the status of the optic nerve and retina, ruling out any ocular pathology. The patients were then subjected to OCT scanning to measure optic nerve head and macular parameters. Optical coherence tomography was performed using CIRRUS\u2122 HD OCT (500-21822) (version 8.0.0.518) (Carl Zeiss Meditec, Dublin, CA, USA). The analyzed area was centered manually, and the absence of segmentation errors was confirmed for each scan. RE Avg RNFL and LE Avg RNFL showed weak correlations with ALSFRS, indicated by Pearson Correlation coefficients of 0.073 and -0.026, respectively. The p-values (0.637 and 0.86) suggested that these correlations were not statistically significant. RE Avg GCL and LE Avg GCL, on the other hand, exhibited moderate positive correlations with ALSFRS scores, with correlation coefficients of 0.337 (RE) and 0.389 (LE). These correlations were statistically significant, as indicated by p-values of 0.021 and 0.006, respectively, suggesting a substantial association between GCL thickness and ALS functional outcomes. All patients in our study were clinically diagnosed cases of ALS, as per the El Escorial criteria. Age group-wise analysis showed statistically significant thinning overall as well as quadrant-wise RNFL parameters in patients less than 50 years compared to age-matched controls, indicating that the pathological process occurring in larger motor neurons in ALS might also be happening in smaller sensory neurons of the retina, causing thinning, which was not due to age-related process. Although GCIPL thinning was occurring in our cases, though statistically not significant compared to control, the significant positive correlation observed between GCIPL and ALS functional outcome and between RNFL and GCIPL measurements highlighted the fact that though the axonal degeneration in retinal neurons might not be translating to the same extent in ganglion cells in ALS, the subtle thinning of GCIPL correlated strongly with functional disability in patients with ALS, implying better functional scores with higher values of GCIPL parameters. In summary, GCL measurements in both eyes showed a notable relationship with ALSFRS, whereas RNFL did not appear to correlate significantly."

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies."

Mural cell loss or malfunction has been associated with numerous diseases including diabetic retinopathy, stroke and amyotrophic lateral sclerosis. In this work, we investigate the role of CDC42 in mural cells in vivo, using the developing mouse retina as a model. In this study, we generated a mouse model for Cdc42 deletion in mural cells by crossing Pdgfrb-CreERT2 mice with Cdc42flox/flox mice. This model (Cdc42i\u0394MC) allowed us to investigate the role of CDC42 in pericytes and smooth muscle cells in the developing and adult retinal vasculature. We find that, during postnatal development, CDC42 is required in both, pericytes and smooth muscle cells to maintain proper cell morphology, mural cell coverage and distribution. During retinal angiogenesis, Cdc42-depleted pericytes lag behind the sprouting front and exhibit decreased proliferation. Consequently, capillaries at the sprouting front remain pericyte deprived, become dilated and are prone to increased vascular leakage. In addition, arteries and arterioles deviate from their normal growth directions and trajectory. While in the adult retina, mural cell coverage normalizes and pericytes adopt a normal morphology, smooth muscle cell morphologies remain abnormal and arteriolar branching angles are markedly reduced. Our findings demonstrate that CDC42 is required for mural cell migration and proliferation and suggest that mural cells are essential for normal morphogenesis and patterning of the developing retinal vasculature."

Beyond its physiological roles, the dysregulation of NPY expression has been documented in several neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Machado-Joseph disease, and retinal disorders such as diabetic retinopathy and glaucoma. These alterations in NPY levels and receptor activity highlight its potential not only as a biomarker for disease progression but also as a promising therapeutic target. Previous evidence revealed that NPY exerts neuroprotection by alleviating excitotoxicity, oxidative stress, mitochondrial dysfunction, and neuroinflammation while concurrently facilitating neurogenesis, synaptic plasticity, and cellular resilience. NPY activates receptor-mediated intracellular signaling cascades like PI3K/Akt, MAPK/ERK, and p38K, that control cellular survival, proteostasis, and inflammation and thereby influence disease trajectories. Understanding NPY operation with these mechanisms can unveil new avenues for targeted therapy. Current insights into the complex roles of NPY in neurodegeneration are discussed in this review, and their implications in diagnostic and treatment strategies are addressed."

Since the retina is ontogenically brain-derived, we hypothesised that retinal biomarkers could be used, alone or in combination with other simple tests, to screen for MCI in people with diabetes. Baseline data from participants screened for RECOGNISED, a Horizon 2020-funded European project, were analysed. Main eligibility criteria for RECOGNISED included age \u226565 years, type 2 diabetes of over 5 years standing, no previous history of stroke or neurodegenerative disease, and no overt diabetic retinopathy or only mild-to-moderate non-proliferative diabetic retinopathy. Baseline characteristics of participants, including scores from the Montreal Cognitive Assessment test (MoCA) and Self-Administered Gerocognitive Examination, the Diabetes Specific Dementia Risk Score (DSDRS) and ophthalmological endpoints gathered from standardised seven field colour fundus photography, spectral domain optical coherence tomography, microperimetry and a hand-held portable electroretinography device (RETeval), were obtained and used in the work presented here as potential screening predictors for presence of MCI. MCI and normocognition (NC) were determined based on a full neuropsychological test battery and the Clinical Dementia Rating score. A stepwise selection of variables, based on Akaike's information criterion, and logistic regression models for predicting MCI were undertaken. Area under the receiver-operating characteristic curve analyses were used to predict the probability of the presence of MCI as well as sensitivity and specificity cut-off points. A total of 313 people living with diabetes (128 with NC and 185 with MCI) were included. People with diabetes with MCI were older (p=0.006) and had fewer years of education (p<0.001), lower retinal sensitivity (p=0.01) and less capacity of gaze fixation (p\u22640.001) than those with NC. Statistically significant differences in pupillary area ratio (p=0.002) and photopic b-wave amplitude (p=0.03) were detected between people with diabetes with NC and with MCI. Multivariable logistic regression showed that the best model to identify people with diabetes with MCI was that combining retinal sensitivity, gaze fixation, photopic b-wave amplitude and pupillary size change following stimulation, years of education, DSDRS and MoCA score, with an AUC of 0.84 (sensitivity 79.9, specificity 79.0). The visuo-construction domain was the most affected in people with diabetes with MCI and its impairment was independently related to retinal sensitivity and gaze fixation. The assessment of retinal neurodysfunction in combination with simple clinical variables appears useful to identify people with diabetes with MCI. This strategy could optimise current screening of MCI in people living with diabetes."

DNA damage is elevated in both sALS and FTD3 neurons, leading to increased phosphorylation of p53 at Serine 15 and elevated levels of Ku80. Knockdown of either p53 or Ku80 rescues neurodegeneration and increases SIRT1 levels in these neurons. Moreover, ectopic expression of SIRT1 or genetic knockdown of either p53 or Ku80 suppresses retinal neurodegeneration caused by FTD3-associated mutant CHMP2B protein in an in vivo Drosophila model. These findings identify a dysregulated SIRT1-p53 feedback loop as a common pathogenic mechanism and promising therapeutic target in both sporadic and familial ALS/FTD."

A peculiarity of the neurodegenerative processes is the variable susceptibility among distinct neuronal populations, exemplified by the contrasting resilience of motor neurons innervating the ocular motor system and the more vulnerable facial and hypoglossal motor neurons. The crucial role of vascular endothelial growth factor (VEGF) as a neuroprotective factor in the nervous system is well-established since a deficit of VEGF has been related to motoneuronal degeneration. In this study, we investigated the survival of ocular, facial, and hypoglossal motor neurons utilizing the murine SOD1G93A ALS model at various stages of the disease. Our primary objective was to determine whether the survival of the different brainstem motor neurons was linked to disparate VEGF expression levels in resilient and susceptible motor neurons throughout neurodegeneration. Our findings revealed a selective loss of motor neurons exclusively within the vulnerable nuclei. Furthermore, a significantly higher level of VEGF was detected in the more resistant motor neurons, the extraocular ones. We also examined whether TDP-43 dynamics in the brainstem motor neuron of SOD mice was altered. Our data suggests that the increased VEGF levels observed in extraocular motor neurons may potentially underlie their resistance during the neurodegenerative processes in ALS in a TDP-43-independent manner. Our work might help to better understand the underlying mechanisms of selective vulnerability of motor neurons in ALS."

This review aims to explore the use of blood-based NfL as an endpoint in clinical trials of neurodegenerative conditions. A database search of MEDLINE and EMBASE was conducted to identify interventional clinical trials and/or related post hoc analyses for neurodegenerative diseases, published between 2013 and 2024 that reported the use of serum or plasma NfL as an endpoint. Additional studies from reference lists of included trials were manually considered for inclusion where relevant. Data were charted descriptively by disease type and summarised. 49 studies were included, 29 in multiple sclerosis (MS), eight in amyotrophic lateral sclerosis (ALS), six in Alzheimer's disease (AD), and six in other diseases. Across studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response. However, several studies demonstrated a lack of concordance between change in NfL and in clinical outcomes, some of which may be related to the non-disease-modifying mechanisms of the interventions studied. This necessitates careful consideration when applying blood-based NfL as a biomarker endpoint for studies involving such interventions. Blood NfL is a promising biomarker with potential utility as a surrogate endpoint in neurological clinical trials, particularly for diseases with active axonal injury. Further validation, particularly around disease- and intervention-specific interpretation, is needed before blood NfL can be incorporated more routinely as a clinical endpoint."

This study identified elevated serum retinol-binding protein 4 (RBP4) as a risk factor for DR, because it induces retinal neuronal injuries and exacerbates vascular defects. Vitreous RBP4 levels were significantly elevated in patients with DR compared with those with macular disease. Elevated vitreous and serum RBP4 levels exacerbated hyperglycemia-induced endothelial inflammation, retinal vascular leakage, pericyte loss, and acellular capillaries in streptozotocin-induced diabetic mice. Progressive retinal degeneration and impaired electroretinography function were exhibited with RBP4 overexpression, likely through inducing retinal microglial activation and phagocytosis. Microglial depletion via PLX3397 (CSF-1R inhibitor) or inhibition using minocycline (anti-inflammatory tetracycline) significantly mitigated retinal degeneration in RBP4 transgenic (RBP4-Tg) mice. Furthermore, minocycline abolished the enhanced phagocytosis of zymosan in murine microglial BV2 cells induced by RBP4. The application of TAK242 or use of microglia-specific TLR4 knockout markedly reduced retinal neuroinflammation and degeneration in RBP4-Tg mice. Overall, these results suggest that elevated serum and vitreous RBP4 levels may be a risk factor for DR by exacerbating retinal neuronal and vascular injuries. Retinol-binding protein 4 (RBP4) levels are elevated in the vitreous humor of patients with diabetic retinopathy (DR) and in RBP4 transgenic mice. Elevated vitreous RBP4 exacerbates both vascular and neuronal deficits associated with DR in streptozotocin-induced diabetic mice. Hyperglycemia augments the RBP4-induced inflammatory response in retinal microvascular endothelial cells to exacerbate DR-related vascular pathologies. RBP4 triggers retinal microglial activation and phagocytosis via TLR4/nuclear factor-\u03baB/mitogen-activated protein kinase pathway, and microglial depletion or inhibition alleviates RBP4-induced retinal neurodegeneration."

It is caused primarily by pathogenic variants in the WFS1 gene, which encodes a transmembrane endoplasmic reticulum-resident protein involved in the unfolded protein response and cellular calcium homeostasis. Although multiple rodent models of Wolfram syndrome have been developed and shown to exhibit visual defects, some studies have reported significant vision loss prior to any detectable axonal degeneration or myelin abnormalities, and the mechanisms underlying these early visual deficits remain poorly understood. Recent in vitro studies have demonstrated altered synaptic contacts and aberrant neurite morphology in WFS1-deficient cerebral organoids and human iPSC-derived neurons, respectively. These findings prompted us to investigate, for the first time in vivo, whether synaptic and dendritic abnormalities occur in the retina of Wfs1 knockout mice. Using confocal microscopy, we examined retinal and optic nerve histology in Wfs1 knockout mice at 4 and 7 months of age. Our analysis reveals progressive synaptic alterations in the inner plexiform layer, driven by early presynaptic compartment failure. These changes represent the earliest detectable phenotype associated with vision loss in this model and precede overt axonal degeneration. These findings identify early synaptic preservation as a promising therapeutic target for vision loss in Wolfram syndrome."

Common neurodegenerative disorders are Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), spinocerebellar ataxia (SCA), and supranuclear palsy. There is a lack of effective treatment for neurodegenerative diseases, and scientists are putting their efforts into developing therapies against them. Stem cell therapy has emerged as a hope for neurodegenerative disorders since it is not only the damaged neurons that might be replaced, but other neuromodulators and neuroprotectors are secreted. Stem cell terminal differentiation before implantation ensures the implantation of correct cells and molecular markers like carbonic anhydrase II, CNPase (2',3'-cyclic nucleotide 3'-phosphohydrolase), myelin basic protein (MBP), and myelin oligodendrocyte glycoprotein (MOG) elucidate the differentiation. Secretion of various growth factors like epidermal growth factor (EGF), keratinocyte growth factor (KGF), vascular endothelial growth factor-\u03b1 (VEGF-\u03b1), transforming growth factor (TGF), and macrophage inflammatory protein (MIP) supports cell survival, cell proliferation, blood vessel formation, axon regeneration, and neuroglial functional connection formation at the site of degeneration. Adverse effects of stem cell therapy, like teratogenicity and differentiation in different cells other than the desired one under the influence of microenvironment, are a few key concerns. Post-transplantation improved synaptic plasticity, apoptosis inhibition, and reduction in tau-phosphorylation and amyloid beta (A\u03b2) production has been observed in Alzheimer's patients. A large number of experimental, preclinical, and clinical studies have been conducted, and encouraging results have been obtained.

Diffusion tensor imaging analysis of fractional anisotropy (FA) was performed along the length of 50 white matter tracts. We included 2404 eligible participants who underwent brain magnetic resonance imaging (NDC, n\u00a0=\u00a01803 and DM, n\u00a0=\u00a0601). Participants with DM had a mean (\u00b1standard deviation) diagnostic duration of 18\u00a0\u00b1\u00a011\u00a0years, with adequate glycaemic control (HbA1C 52\u00a0\u00b1\u00a013\u00a0mmol/mol), low prevalence of microvascular complications (diabetic retinopathy prevalence, 5.8%), comparable cognitive function to controls but greater self-reported pain.

This analysis suggests that anatomic differences in brain regions are present in a cohort with adequately controlled glycaemia without prevalent microvascular disease when compared with volunteers without diabetes.

Early diagnosis remains challenging due to the absence of reliable and validated biomarkers. Calprotectin, a well-established inflammatory marker in various neuroinflammatory conditions, has paradoxically been found at reduced levels in the blood of ALS patients in a limited number of studies, raising the hypothesis of immune dysregulation rather than classical neuroinflammation. However, these findings are primarily derived from small patient cohorts and have yet to be independently replicated.

While calprotectin may reflect a distinct immunological profile, its standalone diagnostic value remains unclear. Nonetheless, its integration into a multi-analyte biomarker panel could enhance diagnostic precision and biological insight. The review also explores underlying immunological mechanisms, including receptor interactions (RAGE, TLR4, CD33), cellular mediators (microglia, lymphocytes, monocytes), and therapeutic implications. Future research should prioritize mechanistic investigation of calprotectin modulation in ALS, longitudinal validation in larger cohorts, and integration within multimodal biomarker frameworks. A better understanding of disease-specific immune alterations may contribute to earlier diagnosis, stratified patient monitoring, and targeted therapeutic development."

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

This model (Cdc42i\u0394MC) allowed us to investigate the role of CDC42 in pericytes and smooth muscle cells in the developing and adult retinal vasculature. We find that, during postnatal development, CDC42 is required in both, pericytes and smooth muscle cells to maintain proper cell morphology, mural cell coverage and distribution. During retinal angiogenesis, Cdc42-depleted pericytes lag behind the sprouting front and exhibit decreased proliferation. Consequently, capillaries at the sprouting front remain pericyte deprived, become dilated and are prone to increased vascular leakage. In addition, arteries and arterioles deviate from their normal growth directions and trajectory. While in the adult retina, mural cell coverage normalizes and pericytes adopt a normal morphology, smooth muscle cell morphologies remain abnormal and arteriolar branching angles are markedly reduced. Our findings demonstrate that CDC42 is required for mural cell migration and proliferation and suggest that mural cells are essential for normal morphogenesis and patterning of the developing retinal vasculature."

Beyond its physiological roles, the dysregulation of NPY expression has been documented in several neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Machado-Joseph disease, and retinal disorders such as diabetic retinopathy and glaucoma. These alterations in NPY levels and receptor activity highlight its potential not only as a biomarker for disease progression but also as a promising therapeutic target. Previous evidence revealed that NPY exerts neuroprotection by alleviating excitotoxicity, oxidative stress, mitochondrial dysfunction, and neuroinflammation while concurrently facilitating neurogenesis, synaptic plasticity, and cellular resilience. NPY activates receptor-mediated intracellular signaling cascades like PI3K/Akt, MAPK/ERK, and p38K, that control cellular survival, proteostasis, and inflammation and thereby influence disease trajectories. Understanding NPY operation with these mechanisms can unveil new avenues for targeted therapy. Current insights into the complex roles of NPY in neurodegeneration are discussed in this review, and their implications in diagnostic and treatment strategies are addressed."

Since the retina is ontogenically brain-derived, we hypothesised that retinal biomarkers could be used, alone or in combination with other simple tests, to screen for MCI in people with diabetes. Baseline data from participants screened for RECOGNISED, a Horizon 2020-funded European project, were analysed. Main eligibility criteria for RECOGNISED included age \u226565 years, type 2 diabetes of over 5 years standing, no previous history of stroke or neurodegenerative disease, and no overt diabetic retinopathy or only mild-to-moderate non-proliferative diabetic retinopathy. Baseline characteristics of participants, including scores from the Montreal Cognitive Assessment test (MoCA) and Self-Administered Gerocognitive Examination, the Diabetes Specific Dementia Risk Score (DSDRS) and ophthalmological endpoints gathered from standardised seven field colour fundus photography, spectral domain optical coherence tomography, microperimetry and a hand-held portable electroretinography device (RETeval), were obtained and used in the work presented here as potential screening predictors for presence of MCI. MCI and normocognition (NC) were determined based on a full neuropsychological test battery and the Clinical Dementia Rating score. A stepwise selection of variables, based on Akaike's information criterion, and logistic regression models for predicting MCI were undertaken. Area under the receiver-operating characteristic curve analyses were used to predict the probability of the presence of MCI as well as sensitivity and specificity cut-off points. A total of 313 people living with diabetes (128 with NC and 185 with MCI) were included. People with diabetes with MCI were older (p=0.006) and had fewer years of education (p<0.001), lower retinal sensitivity (p=0.01) and less capacity of gaze fixation (p\u22640.001) than those with NC. Statistically significant differences in pupillary area ratio (p=0.002) and photopic b-wave amplitude (p=0.03) were detected between people with diabetes with NC and with MCI. Multivariable logistic regression showed that the best model to identify people with diabetes with MCI was that combining retinal sensitivity, gaze fixation, photopic b-wave amplitude and pupillary size change following stimulation, years of education, DSDRS and MoCA score, with an AUC of 0.84 (sensitivity 79.9, specificity 79.0). The visuo-construction domain was the most affected in people with diabetes with MCI and its impairment was independently related to retinal sensitivity and gaze fixation. The assessment of retinal neurodysfunction in combination with simple clinical variables appears useful to identify people with diabetes with MCI. This strategy could optimise current screening of MCI in people living with diabetes."

Although many existing reviews focus on the link between BBB disruption and neuronal degeneration in the brain, a similar analysis of the BRB integrity in retinal degeneration is currently unavailable. Like the BBB, the inner BRB is established by retinal blood vessels encapsulated in a neurovascular unit. The retinal neurovascular unit and BRB are affected not only in retina-specific neurodegenerative diseases (eg, diabetic retinopathy and retinitis pigmentosa) but also in neurodegenerative diseases that primarily affect the brain (eg, Alzheimer disease and Parkinson disease).

Here we show that SIRT1 levels are decreased and acetylated p53 levels are increased in iPSC-derived neurons from sALS patients and with the FTD3-causing CHMP2B mutation. Ectopic expression of SIRT1 in these patient neurons rescues neurodegeneration and reduces acetylated p53 levels. DNA damage is elevated in both sALS and FTD3 neurons, leading to increased phosphorylation of p53 at Serine 15 and elevated levels of Ku80. Knockdown of either p53 or Ku80 rescues neurodegeneration and increases SIRT1 levels in these neurons. Moreover, ectopic expression of SIRT1 or genetic knockdown of either p53 or Ku80 suppresses retinal neurodegeneration caused by FTD3-associated mutant CHMP2B protein in an in vivo Drosophila model. These findings identify a dysregulated SIRT1-p53 feedback loop as a common pathogenic mechanism and promising therapeutic target in both sporadic and familial ALS/FTD."

A peculiarity of the neurodegenerative processes is the variable susceptibility among distinct neuronal populations, exemplified by the contrasting resilience of motor neurons innervating the ocular motor system and the more vulnerable facial and hypoglossal motor neurons. The crucial role of vascular endothelial growth factor (VEGF) as a neuroprotective factor in the nervous system is well-established since a deficit of VEGF has been related to motoneuronal degeneration. In this study, we investigated the survival of ocular, facial, and hypoglossal motor neurons utilizing the murine SOD1G93A ALS model at various stages of the disease. Our primary objective was to determine whether the survival of the different brainstem motor neurons was linked to disparate VEGF expression levels in resilient and susceptible motor neurons throughout neurodegeneration. Our findings revealed a selective loss of motor neurons exclusively within the vulnerable nuclei. Furthermore, a significantly higher level of VEGF was detected in the more resistant motor neurons, the extraocular ones. We also examined whether TDP-43 dynamics in the brainstem motor neuron of SOD mice was altered. Our data suggests that the increased VEGF levels observed in extraocular motor neurons may potentially underlie their resistance during the neurodegenerative processes in ALS in a TDP-43-independent manner. Our work might help to better understand the underlying mechanisms of selective vulnerability of motor neurons in ALS."

This review aims to explore the use of blood-based NfL as an endpoint in clinical trials of neurodegenerative conditions. A database search of MEDLINE and EMBASE was conducted to identify interventional clinical trials and/or related post hoc analyses for neurodegenerative diseases, published between 2013 and 2024 that reported the use of serum or plasma NfL as an endpoint. Additional studies from reference lists of included trials were manually considered for inclusion where relevant. Data were charted descriptively by disease type and summarised. 49 studies were included, 29 in multiple sclerosis (MS), eight in amyotrophic lateral sclerosis (ALS), six in Alzheimer's disease (AD), and six in other diseases. Across studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response. However, several studies demonstrated a lack of concordance between change in NfL and in clinical outcomes, some of which may be related to the non-disease-modifying mechanisms of the interventions studied. This necessitates careful consideration when applying blood-based NfL as a biomarker endpoint for studies involving such interventions. Blood NfL is a promising biomarker with potential utility as a surrogate endpoint in neurological clinical trials, particularly for diseases with active axonal injury. Further validation, particularly around disease- and intervention-specific interpretation, is needed before blood NfL can be incorporated more routinely as a clinical endpoint."

Several antidepressants have been observed to reduce REM sleep fraction on polysomnography. We investigated whether prescription of REM-suppressing antidepressants (RSAs) versus non-REM-suppressing antidepressants (NRSAs) is associated with differential survival in patients with amyotrophic lateral sclerosis (ALS). Using the U.S. Collaborative Network of the TriNetX Analytics platform, we compared 1-year mortality in ALS patients prescribed RSAs or NRSAs within 3 months of diagnosis, identified by ICD-10-CM-coded encounter diagnoses with riluzole prescription between May 2014 and May 2024. We used Cox proportional hazards models, Kaplan-Meier analysis, and risk difference analysis, with and without propensity score matching (PSM). Among 14,441 patients with ALS and riluzole prescription, 5,057 were prescribed either RSAs (N = 4,177) or NRSAs (N = 880).

RSA prescription was associated with modestly better survival, but this association weakened markedly after matching and cannot establish causation; residual confounding, particularly by indication, cannot be excluded. These findings are hypothesis-generating, and prospective studies incorporating polysomnography and ALS-specific prognostic factors are needed."

This study identified elevated serum retinol-binding protein 4 (RBP4) as a risk factor for DR, because it induces retinal neuronal injuries and exacerbates vascular defects. Vitreous RBP4 levels were significantly elevated in patients with DR compared with those with macular disease. Elevated vitreous and serum RBP4 levels exacerbated hyperglycemia-induced endothelial inflammation, retinal vascular leakage, pericyte loss, and acellular capillaries in streptozotocin-induced diabetic mice. Progressive retinal degeneration and impaired electroretinography function were exhibited with RBP4 overexpression, likely through inducing retinal microglial activation and phagocytosis. Microglial depletion via PLX3397 (CSF-1R inhibitor) or inhibition using minocycline (anti-inflammatory tetracycline) significantly mitigated retinal degeneration in RBP4 transgenic (RBP4-Tg) mice. Furthermore, minocycline abolished the enhanced phagocytosis of zymosan in murine microglial BV2 cells induced by RBP4. The application of TAK242 or use of microglia-specific TLR4 knockout markedly reduced retinal neuroinflammation and degeneration in RBP4-Tg mice. Overall, these results suggest that elevated serum and vitreous RBP4 levels may be a risk factor for DR by exacerbating retinal neuronal and vascular injuries. Retinol-binding protein 4 (RBP4) levels are elevated in the vitreous humor of patients with diabetic retinopathy (DR) and in RBP4 transgenic mice. Elevated vitreous RBP4 exacerbates both vascular and neuronal deficits associated with DR in streptozotocin-induced diabetic mice. Hyperglycemia augments the RBP4-induced inflammatory response in retinal microvascular endothelial cells to exacerbate DR-related vascular pathologies. RBP4 triggers retinal microglial activation and phagocytosis via TLR4/nuclear factor-\u03baB/mitogen-activated protein kinase pathway, and microglial depletion or inhibition alleviates RBP4-induced retinal neurodegeneration."

It is caused primarily by pathogenic variants in the WFS1 gene, which encodes a transmembrane endoplasmic reticulum-resident protein involved in the unfolded protein response and cellular calcium homeostasis. Although multiple rodent models of Wolfram syndrome have been developed and shown to exhibit visual defects, some studies have reported significant vision loss prior to any detectable axonal degeneration or myelin abnormalities, and the mechanisms underlying these early visual deficits remain poorly understood. Recent in vitro studies have demonstrated altered synaptic contacts and aberrant neurite morphology in WFS1-deficient cerebral organoids and human iPSC-derived neurons, respectively. These findings prompted us to investigate, for the first time in vivo, whether synaptic and dendritic abnormalities occur in the retina of Wfs1 knockout mice. Using confocal microscopy, we examined retinal and optic nerve histology in Wfs1 knockout mice at 4 and 7 months of age. Our analysis reveals progressive synaptic alterations in the inner plexiform layer, driven by early presynaptic compartment failure. These changes represent the earliest detectable phenotype associated with vision loss in this model and precede overt axonal degeneration. These findings identify early synaptic preservation as a promising therapeutic target for vision loss in Wolfram syndrome."

Common neurodegenerative disorders are Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), spinocerebellar ataxia (SCA), and supranuclear palsy. There is a lack of effective treatment for neurodegenerative diseases, and scientists are putting their efforts into developing therapies against them. Stem cell therapy has emerged as a hope for neurodegenerative disorders since it is not only the damaged neurons that might be replaced, but other neuromodulators and neuroprotectors are secreted. Stem cell terminal differentiation before implantation ensures the implantation of correct cells and molecular markers like carbonic anhydrase II, CNPase (2',3'-cyclic nucleotide 3'-phosphohydrolase), myelin basic protein (MBP), and myelin oligodendrocyte glycoprotein (MOG) elucidate the differentiation. Secretion of various growth factors like epidermal growth factor (EGF), keratinocyte growth factor (KGF), vascular endothelial growth factor-\u03b1 (VEGF-\u03b1), transforming growth factor (TGF), and macrophage inflammatory protein (MIP) supports cell survival, cell proliferation, blood vessel formation, axon regeneration, and neuroglial functional connection formation at the site of degeneration. Adverse effects of stem cell therapy, like teratogenicity and differentiation in different cells other than the desired one under the influence of microenvironment, are a few key concerns. Post-transplantation improved synaptic plasticity, apoptosis inhibition, and reduction in tau-phosphorylation and amyloid beta (A\u03b2) production has been observed in Alzheimer's patients. A large number of experimental, preclinical, and clinical studies have been conducted, and encouraging results have been obtained.

In this case-controlled biobank study, we aimed to ascertain differences in grey and white matter anatomy in people with DM compared with non-diabetic controls (NDC). This study utilises the UK Biobank prospective, population-based, multicentre study of UK residents. Participants with diabetes and age/gender-matched controls without diabetes were selected in a three-to-one ratio. We excluded people with underlying neurological/neurodegenerative disease. Whole brain, cortical, and subcortical volumes (188 regions) were compared between participants with diabetes against NDC corrected for age, sex, and intracranial volume using univariate regression models, with adjustment for multiple comparisons. Diffusion tensor imaging analysis of fractional anisotropy (FA) was performed along the length of 50 white matter tracts. We included 2404 eligible participants who underwent brain magnetic resonance imaging (NDC, n\u00a0=\u00a01803 and DM, n\u00a0=\u00a0601). Participants with DM had a mean (\u00b1standard deviation) diagnostic duration of 18\u00a0\u00b1\u00a011\u00a0years, with adequate glycaemic control (HbA1C 52\u00a0\u00b1\u00a013\u00a0mmol/mol), low prevalence of microvascular complications (diabetic retinopathy prevalence, 5.8%), comparable cognitive function to controls but greater self-reported pain. Univariate volumetric analyses revealed significant reductions in grey matter volume (whole brain, total, and subcortical grey matter), with mean percentage differences ranging from 2.2% to 7% in people with DM relative to NDC (all p\u00a0<\u00a00.0002). The subcortical (bilateral cerebellar cortex, brainstem, thalamus, central corpus callosum, putamen, and pallidum) and cortical regions linked to sensorimotor (bilateral superior frontal, middle frontal, precentral, and postcentral gyri) and visual functions (bilateral middle and superior occipital gyri), all had lower grey matter volumes in people with DM relative to NDC. People with DM had significantly reduced FA along the length of the thalamocortical radiations, thalamostriatal projections, and commissural fibres of the corpus callosum (all; p\u00a0<\u00a00\u00b7001). This analysis suggests that anatomic differences in brain regions are present in a cohort with adequately controlled glycaemia without prevalent microvascular disease when compared with volunteers without diabetes. We hypothesise that these differences may predate overt end-organ damage and complications such as diabetic neuropathy and retinopathy. Central nervous system alterations/neuroplasticity may occur early in the natural history of microvascular complications; therefore, brain imaging should be considered in future mechanistic and interventional studies of DM."

Early diagnosis remains challenging due to the absence of reliable and validated biomarkers. Calprotectin, a well-established inflammatory marker in various neuroinflammatory conditions, has paradoxically been found at reduced levels in the blood of ALS patients in a limited number of studies, raising the hypothesis of immune dysregulation rather than classical neuroinflammation. However, these findings are primarily derived from small patient cohorts and have yet to be independently replicated. This review critically assesses the emerging role of calprotectin in ALS by comparing it with other candidate biomarkers, including vascular endothelial growth factor (VEGF), apolipoprotein A1 (ApoA1), interleukin-8 (IL-8), interleukin-7 (IL-7), and interleukin-10 (IL-10). While calprotectin may reflect a distinct immunological profile, its standalone diagnostic value remains unclear. Nonetheless, its integration into a multi-analyte biomarker panel could enhance diagnostic precision and biological insight. The review also explores underlying immunological mechanisms, including receptor interactions (RAGE, TLR4, CD33), cellular mediators (microglia, lymphocytes, monocytes), and therapeutic implications. Future research should prioritize mechanistic investigation of calprotectin modulation in ALS, longitudinal validation in larger cohorts, and integration within multimodal biomarker frameworks. A better understanding of disease-specific immune alterations may contribute to earlier diagnosis, stratified patient monitoring, and targeted therapeutic development."

While anti-vascular endothelial growth factor (anti-VEGF) therapy, corticosteroids, laser photocoagulation, and vitreoretinal surgery have improved outcomes, none can permanently prevent disease progression. The complex pathophysiology of DR, which includes inflammation, oxidative stress, and neurodegeneration, highlights the need for additional systemic strategies. This narrative review was informed by a structured search of PubMed, Scopus, and Web of Science covering the period from January 2000 to September 10, 2025. Original studies, systematic reviews, and meta-analyses were included, whereas case reports and editorials were excluded. Findings were synthesized qualitatively. Preclinical models suggest that sodium-glucose cotransporter 2 (SGLT2) inhibitors exert neuroprotective, anti-inflammatory, and antioxidant effects on the retina, preserve the blood-retinal barrier, and reduce vascular endothelial growth factor (VEGF) expression. However, whether these retinal effects are only partially independent of glycemic control remains speculative, as clinical studies have not adequately controlled for changes in glycated hemoglobin (HbA1c) or for differences in concomitant glucose-lowering therapies. Observational clinical studies have associated SGLT2 inhibitor use with a lower risk of DR progression, a reduced incidence of proliferative DR, and fewer vision-threatening interventions compared with some other antihyperglycemic agents. Owing to the established indications in heart failure and chronic kidney disease associated with SGLT2 inhibitors, these agents appear promising for DR prevention and risk modification. However, current clinical evidence is based mainly on observational and retrospective studies and remains vulnerable to confounding and selection bias. Prospective randomized studies with ophthalmic endpoints are needed before firm conclusions can be drawn."

Although many existing reviews focus on the link between BBB disruption and neuronal degeneration in the brain, a similar analysis of the BRB integrity in retinal degeneration is currently unavailable. Like the BBB, the inner BRB is established by retinal blood vessels encapsulated in a neurovascular unit. The retinal neurovascular unit and BRB are affected not only in retina-specific neurodegenerative diseases (eg, diabetic retinopathy and retinitis pigmentosa) but also in neurodegenerative diseases that primarily affect the brain (eg, Alzheimer disease and Parkinson disease). In this review, the link between vascular abnormalities (including BRB disruption) and retinal neurodegeneration in these diseases will be discussed to highlight the pivotal role of BRB integrity in neuronal homeostasis and health."

Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface."

Pericyte loss or dysfunction represents a central pathological feature in diabetic retinopathy (DR) and is increasingly recognized in neurodegenerative diseases as well as in poor stroke outcomes, underscoring an urgent need for therapies that restore pericyte function or promote their regeneration. Here, we utilized a Frizzled4 (FZD4) and Low-Density Lipoprotein Receptor-Related Protein 5 (LRP5) agonist antibody (F4L5.13) to investigate the functional consequences of mimicking \u03b2-catenin-dependent signaling in CNS endothelial cells (ECs), which is physiologically induced by Norrin or WNT7A/B. In platelet-derived growth factor subunit B (Pdgfb) EC-specific knockout (ECKO) mice, a model of severe developmental pericyte deficiency with secondary blood-retina barrier (BRB) defects and hemorrhages, F4L5.13 significantly promoted retinal pericyte/mural cell proliferation and coverage, improved BRB function, reduced hemorrhages, and normalized vascular morphology. F4L5.13 restored Pdgfb mRNA expression levels from non-recombined cells in Pdgfb ECKO retinas. These findings highlight interactions of \u03b2-catenin-dependent signaling and PDGFB production, identify a key pharmacodynamic action of F4L5.13 distinct from anti-VEGF therapies, and suggest that FZD4/LRP5 agonists may have uses as a regenerative pharmacology approach that promotes pericyte coverage in the neurovascular unit."

PANoptosis contributes to the development of various diseases, including bacterial and viral infections, tumors, inflammatory diseases, and neurodegenerative diseases, which offers insights into the pathological mechanisms of these diseases and potential treatments. Retinal ganglion cells (RGCs) are nerve cells located in the final segment of the retina, which belongs to the central nervous system. The loss of RGCs caused by various diseases cannot be reversed. Consequently, safeguarding RGCs from loss is a crucial goal in the treatment of diseases that cause RGCs death (such as trauma, glaucoma, and diabetic retinopathy). Research on the multiple modes of death of RGCs has made some progress and, recently, PANoptosis has been observed during the death of RGCs in different models. In this article, we first give an overview of PANoptosis and summarize the fundamental mechanisms and crosstalk between apoptosis, necroptosis, and pyroptosis, as well as the characteristics of these three modes of cell death that occur in RGCs. Finally, we discuss the current status of research on PANoptosis in neurons and RGCs to establish a theoretical basis for the mechanism of PANoptosis as a novel target for safeguarding RGCs from loss."

We previously showed that the anti-amyotrophic lateral sclerosis (ALS) drug riluzole functions as a PKC inhibitor. Here, we examined the effects of riluzole on pathological changes in diabetic retinopathy. Pathological endpoints examined in vivo included the number of pericytes and integrity of retinal vessels in streptozotocin (STZ)-induced diabetic mice. In addition, PKC activation and the induction of monocyte chemotactic protein (MCP1) were assessed in diabetic mice and in human retinal pericytes exposed to advanced glycation end product (AGE) or modified low-density lipoprotein (mLDL). The diameter of retinal vessels and the number of pericytes were severely reduced, and the levels of MCP1 and PKC were increased in STZ-induced diabetic mice. Administration of riluzole reversed all of these changes. Furthermore, the increased expression of MCP1 in AGE- or mLDL-treated cultured retinal pericytes was inhibited by treatment with riluzole or the PKC inhibitor GF109203X. In silico modeling showed that riluzole fits well within the catalytic pocket of PKC. Taken together, our results demonstrate that riluzole attenuates both MCP1 induction and pericyte loss in diabetic retinopathy, likely through its direct inhibitory effect on PKC."

Retinal sections were evaluated with periodic acid Schiff and phosphorylated (P-NF) and nonphosphorylated (NP-NF) forms of neurofilament with SMI 31 and 32 antibodies. Spheroids identified in the retinal nerve fiber layer were counted and their overall density was calculated in central, peripheral, and peripapillary regions. P-NF intensity was quantified. Morphometric features of ALS cases were compared with age-matched controls using the exact Wilcoxon matched-pairs signed-rank test. Distinct periodic acid Schiff-positive round profiles were identified in the retinal nerve fiber layer of patients with ALS and were most commonly observed in the peripapillary and peripheral retina. The density of periodic acid Schiff-positive spheroids was significantly greater in patients with ALS compared with controls (P = 0.027), with increased density in the peripapillary region (P = 0.047). Spheroids positive for P-NF and NP-NF were detected. P-NF-positive spheroid density was significantly increased in patients with ALS (P = 0.004), while the density of NP-NF spheroids did not differ significantly between ALS and control groups (P > 0.05). P-NF immunoreactivity in the retinal nerve fiber layer was significantly greater in patients with ALS than in controls (P = 0.002). Retinal spheroids and axon pathology discovered in patients with ALS, similar to hallmark findings in spinal cord motor neurons, point to disrupted axon transport as a shared pathogenesis. Retinal manifestations detected in ALS suggest a novel biomarker detectable by noninvasive retinal imaging to help to diagnose and monitor ALS disease."

The OCT parameters of macular retinal thickness (MRT) and ganglion cell-inner plexiform layer (GCIPL) thicknesses were evaluated between diabetic and normal eyes. The receiver operating characteristics (ROC) curve was generated to evaluate the discrimination power of early diabetes. Correlation and multiple regression analysis were performed between ophthalmological parameters and T2DM-related demographic and anthropometric variables, and serum biomarkers and homeostasis model assessment of insulin resistance (HOMA-IR) scores. MRT and GCIPL thicknesses showed significant thinning in patients, especially in inferotemporal area. High body mass index (BMI) correlated with decreased GCIPL thicknesses and elevated intraocular pressure (IOP). A negative correlation between waist-to-hip circumference ratio (WHR) and GCIPL thicknesses was also found. High-density lipoprotein (HDL) and fasting C-peptide (CP0) were associated with GCIPL thickness but only in inferotemporal region (r = 0.20, p = 0.04; r = -0.20, p = 0.05, respectively). Multiple regression analysis showed that increased HOMA-IR scores independently predicted both average (\u03b2 = -0.30, p = 0.05) and inferotemporal (\u03b2 = -0.34, p = 0.03) GCIPL thinning. Retinal thinning in early T2DM was associated with obesity-related metabolic disorders. IR as an independent risk factor for retinal neurodegeneration may increase the risk of developing glaucoma."

A reduction in retinal thickness is an early indicator of diabetic retinopathy (DR), with progressive loss of neuroglia corresponding to DR severity. The brain undergoes similar pathophysiological events as the retina, which contribute to T2D-related cognitive decline. This study explored the relationship between retinal thinning and cognitive decline in the LepR db/db model of T2D. Diabetic db/db and non-diabetic db/+ mice aged 14 and 28 weeks underwent cognitive testing in short and long-term memory domains and in vivo retinal imaging using optical coherence tomography (OCT), followed by plasma metabolic measures and ex vivo quantification of neuroinflammation, oxidative stress and microvascular leakage. At 28 weeks, mice exhibited retinal thinning in the ganglion cell complex and inner nuclear layer, concomitant with diabetic insulin resistance, memory deficits, increased expression of inflammation markers and cerebrovascular leakage. Interestingly, alterations in retinal thickness at both experimental timepoints were correlated with cognitive decline and elevated immune response in the brain and retina. These results suggest that changes in retinal thickness quantified with in vivo OCT imaging may be an indicator of diabetic cognitive dysfunction and neuroinflammation."

This was a cross-sectional observational study. We evaluated retinal layer thickness in 134 ALS patients and 66 HCs using optical coherence tomography (OCT). Particularly, we focused on the macular region and peripapillary retinal nerve fiber layer (p-RNFL). The examination of retinal layers in ALS patients revealed a significant change in the inner nuclear layer (INL), with a pattern of initial thickening followed by thinning, which correlated with disease stages, most notably in the inner nasal quadrant. Moreover, the p-RNFL in the temporal quadrant was thinner in ALS patients compared to HCs. In addition, ALS patients who developed bulbar symptoms exhibited marginally thinner p-RNFL in the temporal quadrant compared to those without bulbar symptoms. Interestingly, a thinner p-RNFL in the temporal quadrant did not correlate with faster disease progression. This study reveals notable changes in the INL and p-RNFL thickness in ALS patients, highlighting the intricate relationship between retinal changes and ALS progression. Despite these retinal alterations, no correlation with disease progression rate was observed. These findings suggest that while OCT shows potential in monitoring ALS, its role in predicting disease course requires further investigation with long-term longitudinal studies and diverse patient cohorts."

Moreover, whether retinal atrophy has a clinical (diagnostic and prognostic) value in these diseases remains unclear. To add light on the pathological significance and clinical value of retinal atrophy in patients with amyotrophic lateral sclerosis (ALS) and Kennedy's disease (KD). Thirty-five ALS, thirty-seven KD, and forty-nine age-matched healthy controls (HC) were included in a one-year longitudinal study. Spectrum-domain optical coherence tomography (OCT) was performed at study entry (T0) and after 12\u00a0months (T1). Disease duration and functional rating scale (FRS) for ALS and KD patients were correlated to retinal thicknesses. Compared to HC, peripapillary retinal nerve fiber layer (pRNFL) thickness was significantly thinner in both ALS (p\u2009=\u20090.034) and KD (p\u2009=\u20090.003). pRNFL was thinner in KD compared to ALS, but the difference was not significant. In KD, pRNFL atrophy significantly correlated with both disease severity (r\u2009=\u20090.296, p\u2009=\u20090.035) and disease duration (r\u2009=\u2009-\u20090.308, p\u2009=\u20090.013) while no significant correlation was found in ALS (disease severity: r\u2009=\u20090.147, p\u2009=\u20090.238; disease duration: r\u2009=\u2009-\u20090.093, p\u2009=\u20090.459). During the follow-up, pRNFL thickness remained stable in KD while significantly decreased in ALS (p\u2009=\u20090.043). Our study provides evidence of retinal atrophy in both ALS and KD and suggests that retinal thinning is a primary local phenomenon in motoneuron diseases. The clinical value of pRNFL atrophy in KD is worthy of further investigation."

A direct assessment of brain SBVs in vivo is currently not feasible. Retinal vessels are considered a \"mirror\" of brain SBVs. In this study, we used optic coherence tomography (OCT)-based measurements to detect changes in retinal blood vessels of ALS patients compared to those of healthy controls. We analysed Spectralis-OCT images of 34 ALS patients and 20 HCs. The inner wall thickness (IWT), outer wall thickness (OWT), and lumen diameter (LD) of retinal vessels were assessed using intensity-based measurements. In addition, the different retinal layers were analysed using automated segmentation software. The correlations between the various retinal layers and clinical parameters [e.g., disease duration and revised ALS functional rating scale (ALS-FRS-R)] were examined. The OWT of retinal vessels was higher in ALS patients than in HCs (p\u00a0=\u00a00.04). There were no differences in the IWT, LD. ALS patients showed a thinning of the outer nuclear layer (ONL) compared to HCs (median 1.63 vs. 1.77, p\u00a0=\u00a00.002). The whole retinal thickness negatively correlated with the ALS-FRS scale (r\u00a0=\u00a00.3, p\u00a0=\u00a00.03). Our study reports retinal vessel pathology in ALS patients. These changes may be related to those observed in SBVs in skin and muscle biopsies.

Pericytes play a key role in maintaining blood-CNS barriers. The BSCB is damaged in patients with amyotrophic lateral sclerosis (ALS). Moreover, transgenic ALS rodents and pericyte-deficient mice develop BSCB disruption with erythrocyte extravasation preceding motor neuron dysfunction. Here, we studied whether BSCB disruption with erythrocyte extravasation and pericyte loss are present in human ALS. We show that 11 of 11 cervical cords from ALS patients, but 0 of 5 non-neurodegenerative disorders controls, possess perivascular deposits of erythrocyte-derived hemoglobin and hemosiderin typically 10-50 \u03bcm in diameter suggestive of erythrocyte extravasation. Immunostaining for CD235a, a specific marker for erythrocytes, confirmed sporadic erythrocyte extravasation in ALS, but not controls. Quantitative analysis revealed a 3.1-fold increase in perivascular hemoglobin deposits in ALS compared to controls showing hemoglobin confined within the vascular lumen, which correlated with 2.5-fold increase in hemosiderin deposits (r = 0.82, p < 0.01). Spinal cord parenchymal accumulation of plasma-derived immunoglobulin G, fibrin and thrombin was demonstrated in ALS, but not controls. Immunostaining for platelet-derived growth factor receptor-\u03b2, a specific marker for CNS pericytes, indicated a 54 % (p < 0.01) reduction in pericyte number in ALS patients compared to controls. Pericyte reduction correlated negatively with the magnitude of BSCB damage as determined by hemoglobin abundance (r = -0.75, p < 0.01). Thus, the BSCB disruption with erythrocyte extravasation and pericyte reductions is present in ALS. Whether similar findings occur in motor cortex and affected brainstem motor nuclei remain to be seen."

Success was reported with adult stem cells (vascular progenitors or adipose stem cells), as well as induced pluripotent stem cells from cord blood. The cells were able to associate with damaged vessels in both pericyte and endothelial lining positions in models of DR and ischemia-reperfusion. In some diabetic models, functional amelioration of vasculature and electroretinograms was noted. Another approach for endogenous progenitor cell therapy is to normalize dysfunctional diabetic bone marrow and residing endothelial progenitors using NO donors, PPAR-\u03b4 and -\u03b3 agonists, or inhibition of TGF-\u03b2. A potentially important strategy would be to reduce neuropathy by stem cell inoculations, either na\u00efve (e.g., paracrine-acting adipose stem cells) or secreting specific neuroprotectants, such as ciliary neurotrophic factor or brain-derived neurotrophic factor that showed benefit in amyotrophic lateral sclerosis and Parkinson's disease. Recent advances in stem cell therapies for diabetic retinal microangiopathy may form the basis of first clinical trials in the near future. Additionally, stem cell therapies may prove beneficial for diabetic corneal disease (diabetic keratopathy) with pronounced epithelial stem cell dysfunction."

This study aimed to identify novel genetic variants associated with DR and evaluate interactions between polygenic risk scores (PRS) and lifestyle factors in a Korean diabetic cohort. Methods: After excluding subjects with non-diabetic retinopathy eye diseases (n = 2519), we analyzed data from 50,361 non-diabetic controls, 4873 diabetic participants without retinopathy (DM-NR), and 165 with diabetic retinopathy (DM-DR). We conducted genome-wide association studies comparing DM-NR and DM-DR groups, performed generalized multifactor dimensionality reduction (GMDR) analysis for epistatic interactions, developed unweighted PRS models, and examined PRS-lifestyle interactions using two-way analysis of covariance. Results: DM-DR prevalence showed strong associations with metabolic syndrome and its components. Five novel genetic variants were identified: ABCA4_rs17110929, MMP2-AS1_rs2576531, FOXP1_rs557869288, MRPS33_rs1533933, and DRD2_rs4936270. A significant three-way epistatic interaction among the first three variants was discovered through GMDR analysis. High-PRS individuals (scores 5-6) showed a 49-fold higher odds ratio of DM-DR compared to low-PRS individuals (scores 0-2; p < 0.0001). MAGMA analysis revealed enrichment in pathways related to protein degradation, vascular function, and neuronal signaling, with predominant upregulation in brain tissues. Significant PRS \u00d7 lifestyle interactions were identified for fruit intake, coffee consumption, alcohol intake, eating duration, and physical activity, with lifestyle factors modifying genetic risk effects (all p < 0.003). Conclusions: These findings identify novel genetic variants and epistatic interactions in DM-DR pathogenesis, supporting the use of PRS-based risk stratification for intensive monitoring and personalized lifestyle interventions. The discovery of brain tissue-enriched pathways suggests DM-DR shares mechanisms with neurodegenerative diseases, expanding therapeutic targets beyond traditional vascular approaches."

SMA is caused by insufficient levels of the Survival Motor Neuron (SMN) protein, which operates as part of the multiprotein SMN complex that includes the DEAD-box RNA helicase Gemin3/DDX20/DP103. C9orf72, SOD1, TDP-43 and FUS are ranked as the four major genes causing familial ALS. Accumulating evidence has revealed a surprising molecular overlap between SMA and ALS. Here, we ask the question of whether Drosophila can also be exploited to study shared pathogenic pathways. Focusing on motor behaviour, muscle mass and survival, we show that disruption of either TBPH/TDP-43 or Caz/FUS enhance defects associated with Gemin3 loss-of-function. Gemin3-associated neuromuscular junction overgrowth was however suppressed. Sod1 depletion had a modifying effect in late adulthood. We also show that Gemin3 self-interacts and Gem3\u0394N, a helicase domain deletion mutant, retains the ability to interact with its wild-type counterpart. Importantly, mutant:wild-type dimers are favoured more than wild-type:wild-type dimers. In addition to reinforcing the link between SMA and ALS, further exploration of mechanistic overlaps is now possible in a genetically tractable model organism. Notably, Gemin3 can be elevated to a candidate for modifying motor neuron degeneration."

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies."

Several such proteins, e.g. TDP-43, aggregate and are toxic when expressed in yeast. Deletion of the ATXN2 ortholog, PBP1, reduces yeast TDP-43 toxicity, which led to identification of ATXN2 as an amyotrophic lateral sclerosis (ALS) risk factor and therapeutic target. Likewise, new yeast neurodegenerative disease models could facilitate identification of other risk factors and targets. Mutations in SS18L1, encoding the calcium-responsive transactivator (CREST) chromatin-remodeling protein, are associated with ALS. We show that CREST is toxic in yeast and forms nuclear and occasionally cytoplasmic foci that stain with Thioflavin-T, a dye indicative of amyloid-like protein. Like the yeast chromatin-remodeling factor SWI1, CREST inhibits silencing of FLO genes. Toxicity of CREST is enhanced by the [PIN+] prion and reduced by deletion of the HSP104 chaperone required for the propagation of many yeast prions. Likewise, deletion of PBP1 reduced CREST toxicity and aggregation. In accord with the yeast data, we show that the Drosophila ortholog of human ATXN2, dAtx2, is a potent enhancer of CREST toxicity. Downregulation of dAtx2 in flies overexpressing CREST in retinal ganglion cells was sufficient to largely rescue the severe degenerative phenotype induced by human CREST. Overexpression caused considerable co-localization of CREST and PBP1/ATXN2 in cytoplasmic foci in both yeast and mammalian cells. Thus, co-aggregation of CREST and PBP1/ATXN2 may serve as one of the mechanisms of PBP1/ATXN2-mediated toxicity. These results extend the spectrum of ALS associated proteins whose toxicity is regulated by PBP1/ATXN2, suggesting that therapies targeting ATXN2 may be effective for a wide range of neurodegenerative diseases."

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."

We previously showed that the anti-amyotrophic lateral sclerosis (ALS) drug riluzole functions as a PKC inhibitor. Here, we examined the effects of riluzole on pathological changes in diabetic retinopathy. Pathological endpoints examined in vivo included the number of pericytes and integrity of retinal vessels in streptozotocin (STZ)-induced diabetic mice. In addition, PKC activation and the induction of monocyte chemotactic protein (MCP1) were assessed in diabetic mice and in human retinal pericytes exposed to advanced glycation end product (AGE) or modified low-density lipoprotein (mLDL). The diameter of retinal vessels and the number of pericytes were severely reduced, and the levels of MCP1 and PKC were increased in STZ-induced diabetic mice. Administration of riluzole reversed all of these changes. Furthermore, the increased expression of MCP1 in AGE- or mLDL-treated cultured retinal pericytes was inhibited by treatment with riluzole or the PKC inhibitor GF109203X. In silico modeling showed that riluzole fits well within the catalytic pocket of PKC. Taken together, our results demonstrate that riluzole attenuates both MCP1 induction and pericyte loss in diabetic retinopathy, likely through its direct inhibitory effect on PKC."

Pericyte loss or dysfunction represents a central pathological feature in diabetic retinopathy (DR) and is increasingly recognized in neurodegenerative diseases as well as in poor stroke outcomes, underscoring an urgent need for therapies that restore pericyte function or promote their regeneration. Here, we utilized a Frizzled4 (FZD4) and Low-Density Lipoprotein Receptor-Related Protein 5 (LRP5) agonist antibody (F4L5.13) to investigate the functional consequences of mimicking \u03b2-catenin-dependent signaling in CNS endothelial cells (ECs), which is physiologically induced by Norrin or WNT7A/B. In platelet-derived growth factor subunit B (Pdgfb) EC-specific knockout (ECKO) mice, a model of severe developmental pericyte deficiency with secondary blood-retina barrier (BRB) defects and hemorrhages, F4L5.13 significantly promoted retinal pericyte/mural cell proliferation and coverage, improved BRB function, reduced hemorrhages, and normalized vascular morphology. F4L5.13 restored Pdgfb mRNA expression levels from non-recombined cells in Pdgfb ECKO retinas. These findings highlight interactions of \u03b2-catenin-dependent signaling and PDGFB production, identify a key pharmacodynamic action of F4L5.13 distinct from anti-VEGF therapies, and suggest that FZD4/LRP5 agonists may have uses as a regenerative pharmacology approach that promotes pericyte coverage in the neurovascular unit."

PANoptosis contributes to the development of various diseases, including bacterial and viral infections, tumors, inflammatory diseases, and neurodegenerative diseases, which offers insights into the pathological mechanisms of these diseases and potential treatments. Retinal ganglion cells (RGCs) are nerve cells located in the final segment of the retina, which belongs to the central nervous system. The loss of RGCs caused by various diseases cannot be reversed. Consequently, safeguarding RGCs from loss is a crucial goal in the treatment of diseases that cause RGCs death (such as trauma, glaucoma, and diabetic retinopathy). Research on the multiple modes of death of RGCs has made some progress and, recently, PANoptosis has been observed during the death of RGCs in different models. In this article, we first give an overview of PANoptosis and summarize the fundamental mechanisms and crosstalk between apoptosis, necroptosis, and pyroptosis, as well as the characteristics of these three modes of cell death that occur in RGCs. Finally, we discuss the current status of research on PANoptosis in neurons and RGCs to establish a theoretical basis for the mechanism of PANoptosis as a novel target for safeguarding RGCs from loss."

Retinal sections were evaluated with periodic acid Schiff and phosphorylated (P-NF) and nonphosphorylated (NP-NF) forms of neurofilament with SMI 31 and 32 antibodies. Spheroids identified in the retinal nerve fiber layer were counted and their overall density was calculated in central, peripheral, and peripapillary regions. P-NF intensity was quantified. Morphometric features of ALS cases were compared with age-matched controls using the exact Wilcoxon matched-pairs signed-rank test. Distinct periodic acid Schiff-positive round profiles were identified in the retinal nerve fiber layer of patients with ALS and were most commonly observed in the peripapillary and peripheral retina. The density of periodic acid Schiff-positive spheroids was significantly greater in patients with ALS compared with controls (P = 0.027), with increased density in the peripapillary region (P = 0.047). Spheroids positive for P-NF and NP-NF were detected. P-NF-positive spheroid density was significantly increased in patients with ALS (P = 0.004), while the density of NP-NF spheroids did not differ significantly between ALS and control groups (P > 0.05). P-NF immunoreactivity in the retinal nerve fiber layer was significantly greater in patients with ALS than in controls (P = 0.002). Retinal spheroids and axon pathology discovered in patients with ALS, similar to hallmark findings in spinal cord motor neurons, point to disrupted axon transport as a shared pathogenesis.

The OCT parameters of macular retinal thickness (MRT) and ganglion cell-inner plexiform layer (GCIPL) thicknesses were evaluated between diabetic and normal eyes. The receiver operating characteristics (ROC) curve was generated to evaluate the discrimination power of early diabetes. Correlation and multiple regression analysis were performed between ophthalmological parameters and T2DM-related demographic and anthropometric variables, and serum biomarkers and homeostasis model assessment of insulin resistance (HOMA-IR) scores. MRT and GCIPL thicknesses showed significant thinning in patients, especially in inferotemporal area. High body mass index (BMI) correlated with decreased GCIPL thicknesses and elevated intraocular pressure (IOP). A negative correlation between waist-to-hip circumference ratio (WHR) and GCIPL thicknesses was also found. High-density lipoprotein (HDL) and fasting C-peptide (CP0) were associated with GCIPL thickness but only in inferotemporal region (r = 0.20, p = 0.04; r = -0.20, p = 0.05, respectively). Multiple regression analysis showed that increased HOMA-IR scores independently predicted both average (\u03b2 = -0.30, p = 0.05) and inferotemporal (\u03b2 = -0.34, p = 0.03) GCIPL thinning. Retinal thinning in early T2DM was associated with obesity-related metabolic disorders. IR as an independent risk factor for retinal neurodegeneration may increase the risk of developing glaucoma."

A reduction in retinal thickness is an early indicator of diabetic retinopathy (DR), with progressive loss of neuroglia corresponding to DR severity. The brain undergoes similar pathophysiological events as the retina, which contribute to T2D-related cognitive decline. This study explored the relationship between retinal thinning and cognitive decline in the LepR db/db model of T2D. Diabetic db/db and non-diabetic db/+ mice aged 14 and 28 weeks underwent cognitive testing in short and long-term memory domains and in vivo retinal imaging using optical coherence tomography (OCT), followed by plasma metabolic measures and ex vivo quantification of neuroinflammation, oxidative stress and microvascular leakage. At 28 weeks, mice exhibited retinal thinning in the ganglion cell complex and inner nuclear layer, concomitant with diabetic insulin resistance, memory deficits, increased expression of inflammation markers and cerebrovascular leakage. Interestingly, alterations in retinal thickness at both experimental timepoints were correlated with cognitive decline and elevated immune response in the brain and retina. These results suggest that changes in retinal thickness quantified with in vivo OCT imaging may be an indicator of diabetic cognitive dysfunction and neuroinflammation."

This was a cross-sectional observational study. We evaluated retinal layer thickness in 134 ALS patients and 66 HCs using optical coherence tomography (OCT). Particularly, we focused on the macular region and peripapillary retinal nerve fiber layer (p-RNFL). The examination of retinal layers in ALS patients revealed a significant change in the inner nuclear layer (INL), with a pattern of initial thickening followed by thinning, which correlated with disease stages, most notably in the inner nasal quadrant. Moreover, the p-RNFL in the temporal quadrant was thinner in ALS patients compared to HCs. In addition, ALS patients who developed bulbar symptoms exhibited marginally thinner p-RNFL in the temporal quadrant compared to those without bulbar symptoms. Interestingly, a thinner p-RNFL in the temporal quadrant did not correlate with faster disease progression. This study reveals notable changes in the INL and p-RNFL thickness in ALS patients, highlighting the intricate relationship between retinal changes and ALS progression. Despite these retinal alterations, no correlation with disease progression rate was observed. These findings suggest that while OCT shows potential in monitoring ALS, its role in predicting disease course requires further investigation with long-term longitudinal studies and diverse patient cohorts."

Moreover, whether retinal atrophy has a clinical (diagnostic and prognostic) value in these diseases remains unclear. To add light on the pathological significance and clinical value of retinal atrophy in patients with amyotrophic lateral sclerosis (ALS) and Kennedy's disease (KD). Thirty-five ALS, thirty-seven KD, and forty-nine age-matched healthy controls (HC) were included in a one-year longitudinal study. Spectrum-domain optical coherence tomography (OCT) was performed at study entry (T0) and after 12\u00a0months (T1). Disease duration and functional rating scale (FRS) for ALS and KD patients were correlated to retinal thicknesses. Compared to HC, peripapillary retinal nerve fiber layer (pRNFL) thickness was significantly thinner in both ALS (p\u2009=\u20090.034) and KD (p\u2009=\u20090.003). pRNFL was thinner in KD compared to ALS, but the difference was not significant. In KD, pRNFL atrophy significantly correlated with both disease severity (r\u2009=\u20090.296, p\u2009=\u20090.035) and disease duration (r\u2009=\u2009-\u20090.308, p\u2009=\u20090.013) while no significant correlation was found in ALS (disease severity: r\u2009=\u20090.147, p\u2009=\u20090.238; disease duration: r\u2009=\u2009-\u20090.093, p\u2009=\u20090.459). During the follow-up, pRNFL thickness remained stable in KD while significantly decreased in ALS (p\u2009=\u20090.043). Our study provides evidence of retinal atrophy in both ALS and KD and suggests that retinal thinning is a primary local phenomenon in motoneuron diseases. The clinical value of pRNFL atrophy in KD is worthy of further investigation."

A direct assessment of brain SBVs in vivo is currently not feasible. Retinal vessels are considered a \"mirror\" of brain SBVs. In this study, we used optic coherence tomography (OCT)-based measurements to detect changes in retinal blood vessels of ALS patients compared to those of healthy controls. We analysed Spectralis-OCT images of 34 ALS patients and 20 HCs. The inner wall thickness (IWT), outer wall thickness (OWT), and lumen diameter (LD) of retinal vessels were assessed using intensity-based measurements. In addition, the different retinal layers were analysed using automated segmentation software. The correlations between the various retinal layers and clinical parameters [e.g., disease duration and revised ALS functional rating scale (ALS-FRS-R)] were examined. The OWT of retinal vessels was higher in ALS patients than in HCs (p\u00a0=\u00a00.04). There were no differences in the IWT, LD. ALS patients showed a thinning of the outer nuclear layer (ONL) compared to HCs (median 1.63 vs. 1.77, p\u00a0=\u00a00.002). The whole retinal thickness negatively correlated with the ALS-FRS scale (r\u00a0=\u00a00.3, p\u00a0=\u00a00.03). Our study reports retinal vessel pathology in ALS patients. These changes may be related to those observed in SBVs in skin and muscle biopsies.

Pericytes play a key role in maintaining blood-CNS barriers. The BSCB is damaged in patients with amyotrophic lateral sclerosis (ALS). Moreover, transgenic ALS rodents and pericyte-deficient mice develop BSCB disruption with erythrocyte extravasation preceding motor neuron dysfunction. Here, we studied whether BSCB disruption with erythrocyte extravasation and pericyte loss are present in human ALS. We show that 11 of 11 cervical cords from ALS patients, but 0 of 5 non-neurodegenerative disorders controls, possess perivascular deposits of erythrocyte-derived hemoglobin and hemosiderin typically 10-50 \u03bcm in diameter suggestive of erythrocyte extravasation. Immunostaining for CD235a, a specific marker for erythrocytes, confirmed sporadic erythrocyte extravasation in ALS, but not controls. Quantitative analysis revealed a 3.1-fold increase in perivascular hemoglobin deposits in ALS compared to controls showing hemoglobin confined within the vascular lumen, which correlated with 2.5-fold increase in hemosiderin deposits (r = 0.82, p < 0.01). Spinal cord parenchymal accumulation of plasma-derived immunoglobulin G, fibrin and thrombin was demonstrated in ALS, but not controls. Immunostaining for platelet-derived growth factor receptor-\u03b2, a specific marker for CNS pericytes, indicated a 54 % (p < 0.01) reduction in pericyte number in ALS patients compared to controls. Pericyte reduction correlated negatively with the magnitude of BSCB damage as determined by hemoglobin abundance (r = -0.75, p < 0.01). Thus, the BSCB disruption with erythrocyte extravasation and pericyte reductions is present in ALS. Whether similar findings occur in motor cortex and affected brainstem motor nuclei remain to be seen."

Success was reported with adult stem cells (vascular progenitors or adipose stem cells), as well as induced pluripotent stem cells from cord blood. The cells were able to associate with damaged vessels in both pericyte and endothelial lining positions in models of DR and ischemia-reperfusion. In some diabetic models, functional amelioration of vasculature and electroretinograms was noted. Another approach for endogenous progenitor cell therapy is to normalize dysfunctional diabetic bone marrow and residing endothelial progenitors using NO donors, PPAR-\u03b4 and -\u03b3 agonists, or inhibition of TGF-\u03b2. A potentially important strategy would be to reduce neuropathy by stem cell inoculations, either na\u00efve (e.g., paracrine-acting adipose stem cells) or secreting specific neuroprotectants, such as ciliary neurotrophic factor or brain-derived neurotrophic factor that showed benefit in amyotrophic lateral sclerosis and Parkinson's disease. Recent advances in stem cell therapies for diabetic retinal microangiopathy may form the basis of first clinical trials in the near future. Additionally, stem cell therapies may prove beneficial for diabetic corneal disease (diabetic keratopathy) with pronounced epithelial stem cell dysfunction."

This study aimed to identify novel genetic variants associated with DR and evaluate interactions between polygenic risk scores (PRS) and lifestyle factors in a Korean diabetic cohort. Methods: After excluding subjects with non-diabetic retinopathy eye diseases (n = 2519), we analyzed data from 50,361 non-diabetic controls, 4873 diabetic participants without retinopathy (DM-NR), and 165 with diabetic retinopathy (DM-DR). We conducted genome-wide association studies comparing DM-NR and DM-DR groups, performed generalized multifactor dimensionality reduction (GMDR) analysis for epistatic interactions, developed unweighted PRS models, and examined PRS-lifestyle interactions using two-way analysis of covariance. Results: DM-DR prevalence showed strong associations with metabolic syndrome and its components. Five novel genetic variants were identified: ABCA4_rs17110929, MMP2-AS1_rs2576531, FOXP1_rs557869288, MRPS33_rs1533933, and DRD2_rs4936270. A significant three-way epistatic interaction among the first three variants was discovered through GMDR analysis. High-PRS individuals (scores 5-6) showed a 49-fold higher odds ratio of DM-DR compared to low-PRS individuals (scores 0-2; p < 0.0001). MAGMA analysis revealed enrichment in pathways related to protein degradation, vascular function, and neuronal signaling, with predominant upregulation in brain tissues. Significant PRS \u00d7 lifestyle interactions were identified for fruit intake, coffee consumption, alcohol intake, eating duration, and physical activity, with lifestyle factors modifying genetic risk effects (all p < 0.003). Conclusions: These findings identify novel genetic variants and epistatic interactions in DM-DR pathogenesis, supporting the use of PRS-based risk stratification for intensive monitoring and personalized lifestyle interventions. The discovery of brain tissue-enriched pathways suggests DM-DR shares mechanisms with neurodegenerative diseases, expanding therapeutic targets beyond traditional vascular approaches."

SMA is caused by insufficient levels of the Survival Motor Neuron (SMN) protein, which operates as part of the multiprotein SMN complex that includes the DEAD-box RNA helicase Gemin3/DDX20/DP103. C9orf72, SOD1, TDP-43 and FUS are ranked as the four major genes causing familial ALS. Accumulating evidence has revealed a surprising molecular overlap between SMA and ALS. Here, we ask the question of whether Drosophila can also be exploited to study shared pathogenic pathways. Focusing on motor behaviour, muscle mass and survival, we show that disruption of either TBPH/TDP-43 or Caz/FUS enhance defects associated with Gemin3 loss-of-function. Gemin3-associated neuromuscular junction overgrowth was however suppressed. Sod1 depletion had a modifying effect in late adulthood. We also show that Gemin3 self-interacts and Gem3\u0394N, a helicase domain deletion mutant, retains the ability to interact with its wild-type counterpart. Importantly, mutant:wild-type dimers are favoured more than wild-type:wild-type dimers. In addition to reinforcing the link between SMA and ALS, further exploration of mechanistic overlaps is now possible in a genetically tractable model organism. Notably, Gemin3 can be elevated to a candidate for modifying motor neuron degeneration."

Several such proteins, e.g. TDP-43, aggregate and are toxic when expressed in yeast. Deletion of the ATXN2 ortholog, PBP1, reduces yeast TDP-43 toxicity, which led to identification of ATXN2 as an amyotrophic lateral sclerosis (ALS) risk factor and therapeutic target. Likewise, new yeast neurodegenerative disease models could facilitate identification of other risk factors and targets. Mutations in SS18L1, encoding the calcium-responsive transactivator (CREST) chromatin-remodeling protein, are associated with ALS. We show that CREST is toxic in yeast and forms nuclear and occasionally cytoplasmic foci that stain with Thioflavin-T, a dye indicative of amyloid-like protein. Like the yeast chromatin-remodeling factor SWI1, CREST inhibits silencing of FLO genes. Toxicity of CREST is enhanced by the [PIN+] prion and reduced by deletion of the HSP104 chaperone required for the propagation of many yeast prions. Likewise, deletion of PBP1 reduced CREST toxicity and aggregation. In accord with the yeast data, we show that the Drosophila ortholog of human ATXN2, dAtx2, is a potent enhancer of CREST toxicity. Downregulation of dAtx2 in flies overexpressing CREST in retinal ganglion cells was sufficient to largely rescue the severe degenerative phenotype induced by human CREST. Overexpression caused considerable co-localization of CREST and PBP1/ATXN2 in cytoplasmic foci in both yeast and mammalian cells. Thus, co-aggregation of CREST and PBP1/ATXN2 may serve as one of the mechanisms of PBP1/ATXN2-mediated toxicity. These results extend the spectrum of ALS associated proteins whose toxicity is regulated by PBP1/ATXN2, suggesting that therapies targeting ATXN2 may be effective for a wide range of neurodegenerative diseases."

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."

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches.

Based on the provided literature, there is no evidence identifying a recent NPDR clinical trial that investigates or reveals specific data concerning ALS. However, both conditions are characterized as neurodegenerative disorders sharing common pathological mechanisms, including neuroinflammation, mitochondrial dysfunction, and the potential utility of extracellular vesicles (EVs) as biomarkers.\n\n### [INTRODUCTION & JUSTIFICATION]\nCurrent scientific literature posits that diabetic retinopathy (DR) is increasingly classified as a neurovascular degenerative disorder, where neurodegenerative changes frequently precede clinically observable vascular lesions. Similarly, amyotrophic lateral sclerosis (ALS) is defined by progressive motor neuron loss involving chronic neuroinflammation and glial dysfunction. While the provided dataset discusses these pathologies as sharing underlying molecular vulnerabilities, it contains no reports of NPDR clinical trials that directly examine ALS. The integration of these fields is primarily found in the search for shared biomarkers, such as neurofilament light chain (NfL), and the investigation of common pathways like the \"Autophagy-Senescence-Inflammasome (ASI) axis.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Diabetic retinopathy and ALS share a reliance on the ubiquitin-proteasome system (UPS) for neuronal homeostasis; failure in this pathway is a common feature across major neurodegenerative diseases.\n*   Retinal pigment epithelium (RPE) cells in diabetes models demonstrate insulin secretion capabilities, suggesting a metabolic reprogramming analogous to processes involved in other neurodegenerative diseases.\n*   Extracellular vesicles (EVs) are identified as systemic mediators of communication between the retina and other tissues in diabetes, mirroring their role in spreading proteopathic seeds in ALS.\n*   C9ORF72 deficiency, the most common genetic cause of ALS, has been shown to induce tissue-specific neuronal loss in the zebrafish retina, including disturbances in outer segment structure.\n*   Mitochondrial aging and the production of reactive oxygen species (ROS) act as a central mechanistic hub for inflammation in both the neural retina and the CNS motor neurons.\n*   Both conditions feature sex-associated heterogeneity in their neuroinflammatory profiles, emphasizing the need for precision-based, sex-stratified clinical research.\n*   The cGAS-STING signaling pathway is increasingly implicated in both DR progression and ALS, representing a potential cross-disease therapeutic target for reducing neuroinflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

However, the literature identifies significant mechanistic overlaps and commonalities in their respective pathologies, particularly concerning the retinal neurovascular unit. Evidence confirms that retinal neurodegeneration is a shared feature in both conditions, and specific proteins\u2014such as VEGF, calprotectin, and NPY\u2014are implicated in the neurodegenerative processes of both the retina and motor neurons. While there is no direct clinical trial overlap, the datasets strongly support a conceptual intersection regarding neurovascular vulnerability and biomarker development.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific investigation into the potential for shared biomarkers and therapeutic targets between NPDR and ALS highlights a convergent pathology.

While the provided studies do not describe a single clinical trial concurrently testing a drug on both NPDR patients and ALS patients simultaneously, they demonstrate that the retinal neurovascular unit pathology in diabetes\u2014often analyzed during NPDR studies\u2014shares fundamental molecular mechanisms (such as pericyte loss, blood-retinal barrier breakdown, and microglial activation) with ALS.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific investigation of diabetic retinopathy and amyotrophic lateral sclerosis (ALS) highlights shared neurovascular and neurodegenerative pathology. Research indicates that pharmacological interventions effective in ALS, such as riluzole, show protective effects against retinal damage in diabetic models, suggesting that the retina may serve as a diagnostic and therapeutic surrogate for motor neuron disease studies.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe convergence of ocular and neurodegenerative research has identified the retina as an accessible extension of the central nervous system, sharing embryological and pathological features with motor neuron diseases. Diabetic retinopathy (DR), particularly its early non-proliferative stage, is defined by neurodegenerative processes, including the loss of retinal ganglion cells and pericytes, mirroring systemic neurodegeneration seen in ALS.\n\nThe pathophysiological link is robust; pericyte loss is identified as a hallmark of both DR and ALS, with studies confirming that the \"blood-brain barrier and blood-spinal cord barrier (BSCB) limit the entry of plasma components and erythrocytes into the central nervous system (CNS). Pericytes play a key role in maintaining blood-CNS barriers.\" Because the \"retina is considered as an extension of the central nervous system (CNS) as it displays similarities to the brain, the inner blood-retinal barrier, and the blood-brain barrier,\" researchers have begun repurposing ALS therapeutics. A primary example is the utilization of riluzole, where \"We previously showed that the anti-amyotrophic lateral sclerosis (ALS) drug riluzole functions as a PKC inhibitor. Here, we examined the effects of riluzole on pathological changes in diabetic retinopathy.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Retinal imaging, specifically OCT, can document structural modifications in retinal layers, serving as a non-invasive window into systemic neurodegenerative diseases.\n*   Riluzole, designed for ALS, has been successfully repurposed in streptozotocin-induced diabetic mouse models to attenuate pericyte dropout and reduce PKC activation.\n*   The retinal pigment epithelium (RPE) and retinal ganglion cells (RGCs) are common sites of degeneration in both diabetes and ALS, suggesting shared mitochondrial and transport pathway vulnerabilities.\n*   Retinal microglial activation, specifically the M1 pro-inflammatory phenotype, is a conserved response in both the SOD1G93A ALS model and DR.\n*   Elevated markers of inflammation such as LCN2 are implicated in both diabetic retinal neurodegeneration and systemic neurodegenerative conditions.\n*   The depletion of specific ALS-linked proteins like TDP-43 or FUS enhances degenerative defects in neuronal models, showing genetic overlap in regulatory pathways.\n*   High-myopic eyes with longer axial length demonstrate microvascular density alterations that parallel the rarefaction seen in neurodegenerative vascular units.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

ID: 42304926.\n\n\n--- VALIDATED QUOTES ---\nNeurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis, are defined by progressive neuronal loss, protein misfolding, and chronic neuroinflammation, yet effective disease-modifying therapies remain absent.\nDiabetic retinal disease (DRD) has classically been defined as a microvascular complication of diabetes; however, the recent evidence highlighted the key role of neuronal degeneration during the earliest stages of its pathogenesis.\nHere, we synthesise emerging evidence supporting an integrated 'Autophagy-Senescence-Inflammasome (ASI) axis', in which reciprocal interactions among impaired autophagy, senescent glia, and inflammasome signalling establish a self-sustaining cycle of neuroinflammation.\nNeurofilament light chain (NfL) is a structural axonal protein measurable in CSF and blood, increasingly investigated as a biomarker of neuroaxonal injury in clinical and research contexts.\nAmyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder driven by neuroinflammation involving activated microglia and astrocytes, which accelerates the loss of motor neurons.\nOxidative stress is a major contributor to retinal degeneration in ocular neurodegenerative diseases, including glaucoma, where the loss of retinal ganglion cells (RGCs) leads to vision loss.\nReframing DR as a diabetes-driven disorder of early NVU uncoupling may help shift clinical thinking from late vascular rescue toward mechanism-based neurovascular protection, precision phenotyping, and stage-adapted intervention.\nThe retina, an extension of the central nervous system, presents a unique opportunity for monitoring brain pathology due to its accessibility.\nDHE mitigates astrocyte-driven neurotoxicity associated with ALS/FTD-related RNA-binding protein pathology by suppressing inflammatory signaling and enhancing antioxidant defense mechanisms.\nHyperglycemia is a key driver of neuroinflammation in DR. Hyperglycemia results in VDAC1 O-GlcNAcylation in M\u00fcller glia, leading to mtDNA release and ZBP1 activation, thereby linking metabolic stress to neuroinflammation in DR.\nVitamin D exerts neuroprotective effects through multiple mechanisms, including regulation of calcium homeostasis, modulation of immune responses, reduction in oxidative stress, stimulation of neurotrophic factors, and maintenance of blood-brain barrier (BBB) integrity.\nDisruption of this ESCRT-autophagy interface has emerged as a common pathological feature across major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis/frontotemporal dementia.\nGlaucoma is associated with structural and microstructural brain changes beyond the eye to primary, secondary, and higher-order brain regions.\nHuman endogenous retrovirus-K (HERV-K) reactivation is increasingly implicated in amyotrophic lateral sclerosis (ALS), with ongoing clinical trials investigating antiretroviral therapies.\nCSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS.\nTumor necrosis factor alpha (TNF\u03b1) has been implicated in ALS pathogenesis and is considered to exert both neuroprotective and neurotoxic effects, depending on the differential expression of its receptors in distinct regions of the central nervous system.\nCrucially, probabilistic dependency structure via the Bayesian Network revealed a hierarchical pathogenetic topology: rather than parallel associations, latent renal impairment markers (urine protein, BUN, and urine creatinine) and chronic glycemic toxicity (HbA1c) emerged as direct upstream dependency drivers of DR.\nA culturally adapted multidomain lifestyle intervention was feasible across Latin America and resulted in greater cognitive improvements than a flexible health-advice intervention in older adults at risk of cognitive decline.\nUnlike previous reviews that examine EVs separately as biomarkers or therapeutic vehicles, this review integrates emerging evidence supporting EVs as mediators of systemic communication linking pancreatic islets, adipose tissue, immune cells, vascular endothelium, kidney, heart, and retina throughout diabetes progression.\nNeurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis, are defined by progressive neuronal loss, protein misfolding, and chronic neuroinflammation, yet effective disease-modifying therapies remain absent.\nDiabetic retinal disease (DRD) has classically been defined as a microvascular complication of diabetes; however, the recent evidence highlighted the key role of neuronal degeneration during the earliest stages of its pathogenesis.\nHere, we synthesise emerging evidence supporting an integrated 'Autophagy-Senescence-Inflammasome (ASI) axis', in which reciprocal interactions among impaired autophagy, senescent glia, and inflammasome signalling establish a self-sustaining cycle of neuroinflammation.\nNeurofilament light chain (NfL) is a structural axonal protein measurable in CSF and blood, increasingly investigated as a biomarker of neuroaxonal injury in clinical and research contexts.\nAmyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder driven by neuroinflammation involving activated microglia and astrocytes, which accelerates the loss of motor neurons.\nOxidative stress is a major contributor to retinal degeneration in ocular neurodegenerative diseases, including glaucoma, where the loss of retinal ganglion cells (RGCs) leads to vision loss.\nReframing DR as a diabetes-driven disorder of early NVU uncoupling may help shift clinical thinking from late vascular rescue toward mechanism-based neurovascular protection, precision phenotyping, and stage-adapted intervention.\nThe retina, an extension of the central nervous system, presents a unique opportunity for monitoring brain pathology due to its accessibility.\nDHE mitigates astrocyte-driven neurotoxicity associated with ALS/FTD-related RNA-binding protein pathology by suppressing inflammatory signaling and enhancing antioxidant defense mechanisms.\nHyperglycemia is a key driver of neuroinflammation in DR.

However, detailed examination of adult female c9orf72-/- retinas showed prominent neurodegenerative features, including a decrease in retinal thickness, gliosis, and an overall reduction in neurons of all subtypes.\nretinal neurodegeneration is also crucial in DR pathogenesis\nMural cell loss or malfunction has been associated with numerous diseases including diabetic retinopathy, stroke and amyotrophic lateral sclerosis.\nBeyond its physiological roles, the dysregulation of NPY expression has been documented in several neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Machado-Joseph disease, and retinal disorders such as diabetic retinopathy and glaucoma.\nSince the retina is ontogenically brain-derived, we hypothesised that retinal biomarkers could be used, alone or in combination with other simple tests, to screen for MCI in people with diabetes.\nThe retinal neurovascular unit and BRB are affected not only in retina-specific neurodegenerative diseases (eg, diabetic retinopathy and retinitis pigmentosa) but also in neurodegenerative diseases that primarily affect the brain (eg, Alzheimer disease and Parkinson disease).\nMoreover, ectopic expression of SIRT1 or genetic knockdown of either p53 or Ku80 suppresses retinal neurodegeneration caused by FTD3-associated mutant CHMP2B protein in an in vivo Drosophila model.\nThe crucial role of vascular endothelial growth factor (VEGF) as a neuroprotective factor in the nervous system is well-established since a deficit of VEGF has been related to motoneuronal degeneration.\nAcross studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response.\nAmong 14,441 patients with ALS and riluzole prescription, 5,057 were prescribed either RSAs (N = 4,177) or NRSAs (N = 880). The NRSA cohort had a higher risk of death (HR 1.28, 95% CI 1.11 - 1.46), with 1-year survival of 60.73% versus 68.61% for RSAs (log-rank p<0.001).\nOverall, these results suggest that elevated serum and vitreous RBP4 levels may be a risk factor for DR by exacerbating retinal neuronal and vascular injuries.\nThese findings identify early synaptic preservation as a promising therapeutic target for vision loss in Wolfram syndrome.\nWhile AI shows promise in controlled clinical settings (e.g., stroke imaging, melanoma detection), consumer-facing tools often provide overconfident, context-free diagnostic assertions (e.g., 'definitive evidence of ALS'), leading to premature and potentially harmful life-altering decisions.\nInfants with unfavorable neurovascular outcomes had higher baseline levels than those with favorable outcomes (p < 0.05).\nA positron emission tomography (PET) tracer targeting TDP-43 aggregates could improve early diagnosis and guide treatment development for TDP-43-related conditions.\nThere is a lack of effective treatment for neurodegenerative diseases, and scientists are putting their efforts into developing therapies against them.\nThis analysis suggests that anatomic differences in brain regions are present in a cohort with adequately controlled glycaemia without prevalent microvascular disease when compared with volunteers without diabetes.\nThis review critically assesses the emerging role of calprotectin in ALS by comparing it with other candidate biomarkers, including vascular endothelial growth factor (VEGF), apolipoprotein A1 (ApoA1), interleukin-8 (IL-8), interleukin-7 (IL-7), and interleukin-10 (IL-10).\nretinal neurodegeneration is also crucial in DR pathogenesis\nMural cell loss or malfunction has been associated with numerous diseases including diabetic retinopathy, stroke and amyotrophic lateral sclerosis.\nBeyond its physiological roles, the dysregulation of NPY expression has been documented in several neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Machado-Joseph disease, and retinal disorders such as diabetic retinopathy and glaucoma.\nSince the retina is ontogenically brain-derived, we hypothesised that retinal biomarkers could be used, alone or in combination with other simple tests, to screen for MCI in people with diabetes.\nThe retinal neurovascular unit and BRB are affected not only in retina-specific neurodegenerative diseases (eg, diabetic retinopathy and retinitis pigmentosa) but also in neurodegenerative diseases that primarily affect the brain (eg, Alzheimer disease and Parkinson disease).\nMoreover, ectopic expression of SIRT1 or genetic knockdown of either p53 or Ku80 suppresses retinal neurodegeneration caused by FTD3-associated mutant CHMP2B protein in an in vivo Drosophila model.\nThe crucial role of vascular endothelial growth factor (VEGF) as a neuroprotective factor in the nervous system is well-established since a deficit of VEGF has been related to motoneuronal degeneration.\nAcross studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response.\nAmong 14,441 patients with ALS and riluzole prescription, 5,057 were prescribed either RSAs (N = 4,177) or NRSAs (N = 880).

Consequently, safeguarding RGCs from loss is a crucial goal in the treatment of diseases that cause RGCs death (such as trauma, glaucoma, and diabetic retinopathy).\nSeveral scientific results suggest a neurovascular impairment in ALS providing perspectives for the development of new biomarkers and treatments.\nRetinal changes have also been recently highlighted without significant alteration of the visual pathways. Despite the peripheral location of the retina, it is considered as an extension of the central nervous system (CNS) as it displays similarities to the brain, the inner blood-retinal barrier, and the blood-brain barrier.\nWe previously showed that the anti-amyotrophic lateral sclerosis (ALS) drug riluzole functions as a PKC inhibitor. Here, we examined the effects of riluzole on pathological changes in diabetic retinopathy.\nRetinal spheroids and axon pathology discovered in patients with ALS, similar to hallmark findings in spinal cord motor neurons, point to disrupted axon transport as a shared pathogenesis.\nOCT can non-invasively document changes in single retina layer thickness and structure due to neuronal and retinal glial cells (RGC) modifications in systemic and local inflammatory and neurodegenerative diseases.\nIR as an independent risk factor for retinal neurodegeneration may increase the risk of developing glaucoma.\nThe brain undergoes similar pathophysiological events as the retina, which contribute to T2D-related cognitive decline.\nThe examination of retinal layers in ALS patients revealed a significant change in the inner nuclear layer (INL), with a pattern of initial thickening followed by thinning, which correlated with disease stages\nOur study provides evidence of retinal atrophy in both ALS and KD and suggests that retinal thinning is a primary local phenomenon in motoneuron diseases.\nOur study reports retinal vessel pathology in ALS patients. These changes may be related to those observed in SBVs in skin and muscle biopsies.\nThe blood-brain barrier and blood-spinal cord barrier (BSCB) limit the entry of plasma components and erythrocytes into the central nervous system (CNS). Pericytes play a key role in maintaining blood-CNS barriers.\nSuccess was reported with adult stem cells (vascular progenitors or adipose stem cells), as well as induced pluripotent stem cells from cord blood. The cells were able to associate with damaged vessels in both pericyte and endothelial lining positions in models of DR and ischemia-reperfusion.\nThe discovery of brain tissue-enriched pathways suggests DM-DR shares mechanisms with neurodegenerative diseases, expanding therapeutic targets beyond traditional vascular approaches.\nIn conclusion, in the SOD1G93A model (at 120 days), retinal microglial activation occurred, taking a pro-inflammatory phenotype M1, which affected the OPL and inner retinal layers and could be related to RGC loss.\nFocusing on motor behaviour, muscle mass and survival, we show that disruption of either TBPH/TDP-43 or Caz/FUS enhance defects associated with Gemin3 loss-of-function.\nDownregulation of dAtx2 in flies overexpressing CREST in retinal ganglion cells was sufficient to largely rescue the severe degenerative phenotype induced by human CREST.\nIncreasing evidence suggests that long non-coding RNAs (lncRNAs) play significant roles in neurodevelopment, neuronal homeostasis, and disease progression\nWe previously showed that the anti-amyotrophic lateral sclerosis (ALS) drug riluzole functions as a PKC inhibitor.

Exosomes have emerged as key mediators of central nervous system communication and are increasingly central to the biology of neurodegeneration. These nanoscale vesicles transport proteins, lipids, and nucleic acids across cellular and anatomical barriers, influencing synaptic function, immune signaling, and metabolic homeostasis. Under pathological conditions, exosomes facilitate the spread of misfolded proteins such as amyloid-\u03b2, p-tau, \u03b1-synuclein, and TDP-43, thereby accelerating network-level degeneration. At the same time, their cargo exhibits disease-specific molecular signatures detectable in peripheral biofluids, supporting their development as minimally invasive biomarkers for early diagnosis and longitudinal monitoring. Advances in exosome engineering further underscore their potential as therapeutic delivery vehicles capable of crossing the blood-brain barrier and targeting pathogenic pathways with RNA-based therapeutics, proteins, or gene-editing systems. Together, these findings position exosomes as pivotal contributors to both the mechanistic progression and translational targeting of neurodegenerative diseases."

Although autophagy dysfunction, glial senescence, and inflammasome activation are well-established contributors to progressive neurodegeneration, these processes are often analysed independently or through pairwise interactions, leaving their collective contribution to persistent neuroinflammation and disease progression insufficiently defined. Here, we synthesise emerging evidence supporting an integrated 'Autophagy-Senescence-Inflammasome (ASI) axis', in which reciprocal interactions among impaired autophagy, senescent glia, and inflammasome signalling establish a self-sustaining cycle of neuroinflammation. We discuss how defective autophagy promotes mitochondrial dysfunction, oxidative stress, and danger signalling, while senescent astrocytes and microglia amplify inflammatory responses through the senescence-associated secretory phenotype (SASP). These intertwined processes converge on chronic inflammasome activation, with mitochondrial dysfunction emerging as a central mechanistic hub. Evidence across Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, stroke, and chronic neuropathic pain highlight the broad relevance of this pathological network. We further analyse current therapeutic strategies targeting autophagy, senescence, and inflammasome pathways, emphasising the limitations of single-target approaches and the potential of multi-target interventions. By integrating these processes into a unified framework, this review provides new insights into the possible molecular mechanisms underlying neuroinflammaging and identifies the 'ASI axis' as a promising target for neurodegenerative disease-modifying therapies."

This review aims to explore the use of blood-based NfL as an endpoint in clinical trials of neurodegenerative conditions. A database search of MEDLINE and EMBASE was conducted to identify interventional clinical trials and/or related post hoc analyses for neurodegenerative diseases, published between 2013 and 2024 that reported the use of serum or plasma NfL as an endpoint. Additional studies from reference lists of included trials were manually considered for inclusion where relevant. Data were charted descriptively by disease type and summarised. 49 studies were included, 29 in multiple sclerosis (MS), eight in amyotrophic lateral sclerosis (ALS), six in Alzheimer's disease (AD), and six in other diseases. Across studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response. However, several studies demonstrated a lack of concordance between change in NfL and in clinical outcomes, some of which may be related to the non-disease-modifying mechanisms of the interventions studied. This necessitates careful consideration when applying blood-based NfL as a biomarker endpoint for studies involving such interventions. Blood NfL is a promising biomarker with potential utility as a surrogate endpoint in neurological clinical trials, particularly for diseases with active axonal injury. Further validation, particularly around disease- and intervention-specific interpretation, is needed before blood NfL can be incorporated more routinely as a clinical endpoint."

While Secretory leukocyte protease inhibitor (SLPI) is known for its immunomodulatory properties, its specific role in ALS pathogenesis has not been fully established. This study aimed to characterize the expression patterns and functional significance of SLPI in ALS models. The study utilized SOD1G93A mice to analyze the spatiotemporal dynamics of SLPI expression in the gastrocnemius muscle, lumbar spinal cord, and serum across different disease stages. In vitro functional assays were conducted using siRNA-mediated knockdown of SLPI in BV2 (microglia), MA (astrocytes), and NSC-34 (motor neurons) cell lines. Additionally, recombinant SLPI protein was applied to LPS-stimulated BV2 cells to investigate its effect on the TLR4/ NF-\u03baB signaling pathway. In SOD1G93A mice, SLPI was significantly upregulated in the gastrocnemius muscle from the pre-symptomatic stage (60 days) through the late stage (130 days). In the lumbar spinal cord, SLPI showed a transient initial increase but declined sharply by the end-stage; a similar significant reduction was observed in late-stage serum levels. In vitro, SLPI knockdown exacerbated pro-inflammatory cytokine production in all three cell types and impaired the antioxidant capacity of NSC-34 motor neurons. Mechanistically, recombinant SLPI attenuated inflammation in BV2 cells by modulating the TLR4/NF-\u03baB pathway. The dynamic changes in SLPI levels suggest its potential relevance as a candidate molecule for disease staging. Meanwhile, its protective effects in regulating inflammation suggest that it could be a promising therapeutic candidate for mitigating ALS-associated neuroinflammation."

The transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) plays pivotal roles in the cellular defense system against oxidative and xenobiotic stress, making NRF2 activation a promising therapeutic target for ocular neurodegenerative disorders. Covalent NRF2 activators have been extensively studied in clinical trials, leading to the approval of two drugs. However, no non-covalent NRF2- Kelch-like ECH-associated protein 1 (KEAP1) protein-protein interaction (PPI) inhibitors are currently in clinical development, despite their potential for selective and reversible KEAP1 inhibition with fewer side effects. In this study, to develop high potency compounds with suitable properties for an eye drop preparation, we modified the structure of known NRF2-KEAP1 PPI inhibitors. The newly identified compound, SLOS-1811-06 tR1, exhibited neuroprotective effects at concentrations \u22650.01\u202fnM in a hypoxia-induced neurodegeneration model using human-induced pluripotent stem cell (hiPSC)-derived RGCs.

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

This chapter elucidates their utility in detecting biomarkers for the diagnosis and monitoring of progression and response to treatment in different prevalent neurologic conditions. The retina, an extension of the central nervous system, presents a unique opportunity for monitoring brain pathology due to its accessibility. Through highly resolved scans of the retina and optic nerve, OCT and OCTA facilitate the identification of subtle clinical changes occurring during neuroinflammatory, neurodegenerative, and ischemic processes in disorders like multiple sclerosis, Alzheimer and Parkinson disease, anterior ischemic optic neuropathies, and papilledema. Peripapillary nerve fiber layer and macular internal retinal layer thickness on OCT, and vessel density in the superficial retina on OCTA seem to be the most sensitive parameters in detecting axonal injury and neurodegeneration. These metrics hold promise as surrogate markers for cerebral alterations. While OCT and OCTA show considerable potential, continued research is necessary to validate their reliability and clinical significance, considering potential confounding factors such as concurrent ophthalmic pathologies. Nonetheless, these advancements represent significant progress toward enhancing the diagnosis, management, and prediction of outcomes in various neuro-ophthalmic disorders."

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

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

Neurons are particularly vulnerable to these processes due to their post-mitotic nature and complex architecture. Autophagy and the endolysosomal system constitute the primary degradative pathways responsible for maintaining neuronal homeostasis. However, increasing evidence indicates that their effective function critically depends on coordination with the endosomal sorting complexes required for transport (ESCRT). Beyond their canonical role in multivesicular body biogenesis and membrane scission, ESCRT components are now recognized as essential regulators of autophagosome closure, amphisome formation, autophagosome-lysosome fusion, and endolysosomal membrane repair. Disruption of this ESCRT-autophagy interface has emerged as a common pathological feature across major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis/frontotemporal dementia. This review synthesizes evidence from genetic, biochemical, and neuropathological studies to highlight shared molecular nodes, such as ESCRT-III components, the VPS4 ATPase, the adaptor protein ALIX, and late endosomal regulators, including Rab7, that couple membrane remodeling to autophagic flux. Failure of these regulatory checkpoints destabilizes endolysosomal integrity, arrests autophagic maturation, and promotes the accumulation of toxic protein species, thereby driving progressive neuronal degeneration. By framing neurodegeneration through the lens of ESCRT-autophagy coupling failure, this review provides a unified mechanistic perspective that links diverse pathogenic proteins to shared cellular vulnerabilities and identifies ESCRT-mediated membrane dynamics as a critical determinant of neuronal survival."

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

However, there is limited understanding of how HERV-K is trafficked in peripheral biofluids, and the role of exosomes, nano-sized extracellular vesicles, in this process remains largely unexplored. Exosomes offer a stable and cell-specific cargo reservoir that may reflect central pathogenic processes and serve as a minimally invasive biomarker source. In this study, we isolated plasma-derived exosomes from ALS patients (n\u2009=\u200921) and healthy controls (n\u2009=\u200916), and quantified exosomal HERV-K gag, env, and pol transcript levels using SYBR Green qPCR with RNase treatment and normalization to both traditional and exosome-enriched reference genes. HERV-K pol expression was significantly elevated in ALS, with fold-changes ranging from 1.59 to 1.85 (P\u2009=\u20090.037-0.051). env and gag also showed increased expression, though with greater variability. Normalization to the exosome-specific gene SOD2 provided the most consistent signal. These findings suggest that exosomal HERV-K transcripts, particularly pol, could serve as accessible biomarkers for patient stratification and treatment monitoring in HERV-K-targeted ALS trials. This work establishes proof-of-concept for using exosomal cargo to track endogenous retroviral activity in neurodegeneration and supports further investigation of liquid biopsy approaches in ALS precision medicine."

Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease."

We integrated clinical data from the National Health and Nutrition Examination Survey (NHANES) with an independent hospital cohort (Nantong First People's Hospital). A multi-stage feature selection pipeline (Boruta algorithm and LASSO regression) was utilized to identify core predictors. Eight ML algorithms were benchmarked. To transcend conventional \"black-box\" predictions, we coupled SHAP (SHapley Additive exPlanations) for personalized interpretability with a Bayesian Network Directed Acyclic Graph (DAG) to map the probabilistic dependency structure among the selected systemic biomarkers. The LightGBM algorithm outperformed other classifiers, yielding a robust external validation AUC of 0.841 (95% CI: 0.809-0.862). Fourteen key routine predictors were identified, spanning glycemic control, renal function, and lipid metabolism. Crucially, probabilistic dependency structure via the Bayesian Network revealed a hierarchical pathogenetic topology: rather than parallel associations, latent renal impairment markers (urine protein, BUN, and urine creatinine) and chronic glycemic toxicity (HbA1c) emerged as direct upstream dependency drivers of DR. This structural evidence suggests a probabilistic dependency consistent with the 'kidney-eye crosstalk' hypothesis. We successfully deployed a high-performing, non-invasive LightGBM model for early DR screening. By integrating predictive ML with probabilistic dependency structure, this framework not only delivers an accessible, web-based clinical decision support system (CDSS) for resource-constrained settings but also provides preliminary insights into the potential systemic microvascular interplay driving diabetic retinopathy."

Multidomain lifestyle interventions might delay cognitive decline, but populations from Latin America remain under-represented in dementia prevention trials. We aimed to investigate the feasibility of a culturally adapted, multidomain, systematic lifestyle intervention and investigate its effects on global cognitive function in at-risk older adults (aged 60-77 years). The LatAm-FINGERS Initiative for Cognitive Change (hereafter referred to as LatAm-FINGERS) was a single-blind, multicentre, randomised clinical trial conducted in 11 Latin American countries (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Peru, and Uruguay). Individuals aged 60-77 years with high risk of dementia (cardiovascular risk factors, ageing, and dementia risk score \u22656), and suboptimal cognitive performance were randomly assigned (1:1) to receive either a 2-year systematic lifestyle intervention (SLI group) or a flexible lifestyle intervention (FLI group). Randomisation was stratified by the study centre to ensure balance and implemented using permuted blocks of eight. Participants and intervention staff were not masked to group assignment, but individuals who assessed outcomes were masked throughout the trial. The SLI provided structured multidomain lifestyle interventions with supervised support and monitoring; FLI offered health advice. Primary outcomes were trial feasibility (evaluated using selected RE-AIM measures: Reach, Implementation, and Maintenance) and the intervention's effects on global cognitive composite trajectories over 2 years (change in the global cognitive composite score over 2 years). This trial is registered at ClinicalTrials.gov (NCT06492967) and has been completed. Participants were enrolled between Oct 27, 2021, and July 7, 2023; the last participant completed follow-up on Nov 7, 2025. Among 1719 assessed, 1065 participants included in the analytic sample were randomly assigned to the SLI group (n=539) or the FLI group (n=526). Mean age was 67\u00b75 years (SD 4\u00b77), 795 (75%) of 1065 participants were women, and 270 (25%) were men. Self-reported race and ethnicity were: 624 (59%) Mestizo, 288 (27%) White, 72 (7%) Mulatto, 25 (2%) Mixed or other, 18 (2%) Black, 14 (1%) Indigenous, and 24 (2%) did not report race or ethnicity. 877 (82\u00b73%) of 1065 completed the 2-year follow-up. Recruitment effectiveness (Reach) was 62\u00b70%; mean adherence to the SLI group (Implementation) was 71\u00b76% over the entire trial; and frequencies of complete cognitive outcomes data (Maintenance) were 87\u00b79% at 6 months, 85\u00b73% at 12 months, 81\u00b74% at 18 months, and 84\u00b78% at 24 months in the SLI group compared with 86\u00b73% at 6 months, 78\u00b79% at 12 months, 73\u00b74% at 18 months, and 79\u00b78% at 24 months in the FLI group. Dropouts were higher in the FLI group than in the SLI group (20\u00b72% vs 15\u00b72%; p=0\u00b7042). Global cognitive composite scores increased over time in both groups, with a mean annual change of 0\u00b731 SD (95% CI 0\u00b728-0\u00b734) per year in the SLI group and 0\u00b720 SD (0\u00b717-0\u00b723) per year in the FLI group (mean between-group difference of 0\u00b711 SD per year [0\u00b706-0\u00b715; p<0\u00b70001]). Overall, 478 adverse events were reported (412 in the SLI group and 66 in the FLI group). The most common adverse events were musculoskeletal symptoms (113 [21%] in the SLI group, 13 [2%] in the FLI group), upper respiratory infections (50 [9%] in the SLI group, one [<1%] in the FLI group), and COVID-19 infection (31 [6%] events in the SLI group). Serious adverse events occurred in 50 (9%) participants in the SLI group and 24 (5%) participants in the FLI group; none were related to the intervention. There were eight deaths (three in the SLI group and five in the FLI group), and none were related to the intervention. A culturally adapted multidomain lifestyle intervention was feasible across Latin America and resulted in greater cognitive improvements than a flexible health-advice intervention in older adults at risk of cognitive decline. These findings extend the evidence base for multidomain lifestyle interventions to populations historically under-represented in dementia research, supporting their feasibility and scalability as strategies to reduce cognitive decline risk amid the rapidly growing burden of dementia in low-income and middle-income countries.

This review summarizes current knowledge on EV biology, including their classification, cellular sources, biogenesis, uptake mechanisms, and molecular cargo. We discuss the contribution of EV-associated microRNAs to immune dysregulation and \u03b2-cell damage in type 1 diabetes mellitus (T1DM), as well as the role of EVs in insulin resistance, metabolic signaling, and vascular dysfunction in type 2 diabetes mellitus (T2DM). Particular emphasis is placed on EV-mediated modulation of endothelial function, angiogenesis, and tissue repair, alongside their involvement in the impairment of insulin receptor integrity. We further explore how lifestyle factors may influence EV composition and function, highlighting their potential integration into preventive strategies. Finally, we evaluate the emerging therapeutic potential of EVs as biomarkers and delivery systems, while addressing current limitations and future directions. Collectively, EVs represent a promising frontier in understanding diabetes pathophysiology and developing innovative diagnostic and therapeutic approaches.

However, detailed examination of adult female c9orf72-/- retinas showed prominent neurodegenerative features, including a decrease in retinal thickness, gliosis, and an overall reduction in neurons of all subtypes.

Based on the provided literature, there is no evidence identifying a recent NPDR clinical trial that investigates or reveals specific data concerning ALS. However, both conditions are characterized as neurodegenerative disorders sharing common pathological mechanisms, including neuroinflammation, mitochondrial dysfunction, and the potential utility of extracellular vesicles (EVs) as biomarkers.\n\n### [INTRODUCTION & JUSTIFICATION]\nCurrent scientific literature posits that diabetic retinopathy (DR) is increasingly classified as a neurovascular degenerative disorder, where neurodegenerative changes frequently precede clinically observable vascular lesions. Similarly, amyotrophic lateral sclerosis (ALS) is defined by progressive motor neuron loss involving chronic neuroinflammation and glial dysfunction. While the provided dataset discusses these pathologies as sharing underlying molecular vulnerabilities, it contains no reports of NPDR clinical trials that directly examine ALS. The integration of these fields is primarily found in the search for shared biomarkers, such as neurofilament light chain (NfL), and the investigation of common pathways like the \"Autophagy-Senescence-Inflammasome (ASI) axis.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Diabetic retinopathy and ALS share a reliance on the ubiquitin-proteasome system (UPS) for neuronal homeostasis; failure in this pathway is a common feature across major neurodegenerative diseases.\n*   Retinal pigment epithelium (RPE) cells in diabetes models demonstrate insulin secretion capabilities, suggesting a metabolic reprogramming analogous to processes involved in other neurodegenerative diseases.\n*   Extracellular vesicles (EVs) are identified as systemic mediators of communication between the retina and other tissues in diabetes, mirroring their role in spreading proteopathic seeds in ALS.\n*   C9ORF72 deficiency, the most common genetic cause of ALS, has been shown to induce tissue-specific neuronal loss in the zebrafish retina, including disturbances in outer segment structure.\n*   Mitochondrial aging and the production of reactive oxygen species (ROS) act as a central mechanistic hub for inflammation in both the neural retina and the CNS motor neurons.\n*   Both conditions feature sex-associated heterogeneity in their neuroinflammatory profiles, emphasizing the need for precision-based, sex-stratified clinical research.\n*   The cGAS-STING signaling pathway is increasingly implicated in both DR progression and ALS, representing a potential cross-disease therapeutic target for reducing neuroinflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This cross-sectional observational study included forty-eight diabetic subjects without diabetic retinopathy (NDR group), thirty-nine diabetic subjects with mild or moderate non proliferative diabetic retinopathy (DR group), and forty age- and sex-matched healthy adults (control group). Pupil size and pupillary light reflex were measured monocularly using a PLR-3000 dynamic pupillometer, and OCT/OCTA scans were acquired with a Van Gogh SS-OCTA device in all three groups. Both static and dynamic pupillary parameters differed significantly among the three groups (p <0.001). Pairwise comparisons showed that both basal and smallest pupil diameter were smaller in diabetes with or without retinopathy, compared to healthy control. Notably, pupillary dynamics didn't significantly reduce until retinopathy was present. Pupillary parameters showed a positive correlation with the thickness of the ganglion cell layer and inner plexiform layer in the parafovea, and the vessel density of the superficial vascular plexus and intermediate capillary plexus. Static pupillary abnormalities appear before clinical diabetic retinopathy. Both static and dynamic pupillary abnormalities worsen alongside retinal microvascular and neurodegenerative damages in the early stages of diabetes. Evaluation for autonomic nervous dysfunction is recommended for all patients with diabetic retinopathy.\n\nID: 42380113\nTitle: A natural programmable metamaterial controls 3D curvature of compound eyes.\nAbstract: Panoramic vision of the convex compound eyes, common to insects and crustaceans, relies on micrometer-scale curvature variations. These variations generate specialized visual zones adapted to specific tasks, including detecting prey, mates, or predators. However, how such fine-scale curvature is encoded during development remains unknown. We find in Drosophila melanogaster that the basal surface of the developing retina is organized as a supracellular triangular mesh where the size of these triangles is distributed in a species-specific 2D pattern. Functional experiments using genetic perturbations, together with computational modeling, support the notion that this pattern guides adult eye local curvature. A similar pattern in the Drosophila mauritania developing retina indicates an evolutionary conservation of this mechanism. Our findings identify a mechanism of morphogenesis where fine-scale 3D curvature is programmed in the 2D patterning of a tissue with metamaterial properties. This mechanism provides a framework for designing shape-programmable 3D biological surfaces, with broad implications from synthetic morphogenesis to clinical applications.\n\nID: 42356426\nTitle: Neuroprotective Indole Diterpenoids from the Fungus Tolypocladium album DWS131.\nAbstract: Context/Objective: Fungi of the genus Tolypocladium are known for their diverse metabolic capabilities and medicinal potential. Indole diterpenoids (IDTs) represent a structurally unique class of fungal metabolites. Beyond their established roles as mycotoxins, these compounds have recently shown promise for neuroprotective effects. The objective of this study was to isolate and characterize novel IDTs from Tolypocladium album DWS131 and evaluate their neuroprotective activities and underlying mechanisms. Methods: IDTs were isolated through comprehensive chromatographic techniques. Their structures were elucidated using HRESIMS data, 1D/2D NMR spectra, and quantum chemical calculations. Neuroprotective effects were evaluated using glutamate (Glu)-induced R28 cells in vitro and N-methyl-D-aspartic acid-induced mouse models in vivo. A total of 48 mice were utilized for in vivo evaluations, divided into two separate experimental cohorts. In each cohort, mice were randomly assigned to four groups (n = 6 per group). Post-intravitreal injection, retinal survival and visual function were assessed via Brn3a-stained flat-mounts, H&E staining, f-VEP, f-ERG, and OptoDrum. Mechanisms involving the SLC7A11/GPX4/ACSL4 axis were investigated by Western blotting and immunofluorescence. Results: Seven previously undescribed paxilline-type IDTs, tolypindoles A-G (1-7), and two known analogues (8-9) were identified. Compounds 8 and 9 exhibited significant neuroprotection closely associated with the attenuation of oxidative stress and the modulation of ferroptosis-related pathways in Glu-induced R28 cells. In vivo, they preserved retinal ganglion cells, maintained retinal structure, and protected visual function, with compound 8 demonstrating superior efficacy. Mechanistic investigations revealed that both compounds modulate the SLC7A11/GPX4/ACSL4 signaling axis. Conclusions: This study expands the chemical diversity of T. album DWS131. Compounds 8 and 9, characterized by isopentenyl moieties, highlight a promising therapeutic potential for retinal neurodegenerative diseases such as glaucoma.\n\nID: 42353267\nTitle: Neuroprotection in Early Diabetic Retinal Disease Using Eyedrop Delivery.\nAbstract: Diabetic retinal disease (DRD) has classically been defined as a microvascular complication of diabetes; however, the recent evidence highlighted the key role of neuronal degeneration during the earliest stages of its pathogenesis. Therefore, neuroprotection has emerged as a promising therapeutic strategy to prevent disease progression. Topical administration via eyedrops represents a non-invasive approach to deliver neuroprotective agents directly to the retina. This review summarizes the current advances in the field of neuroprotective therapies against early DRD with a special focus on topical delivery, including preclinical and clinical evidence, while discussing the relevance of the transscleral route of absorption in all of them. In this review, the most promising neuroprotective compounds under development will be discussed, highlighting the opportunity that they represent for treating early stages of DRD.\n\nID: 42346801\nTitle: Marine-Derived Fucoidan Modulates Pathways Associated with Age-Related Macular Degeneration in Cellular and Zebrafish Models.\nAbstract: Fucoidan, a sulfated polysaccharide, is known for its beneficial bioactive effects, for example antioxidant, anti-inflammatory, and vascular modulatory effects. Such a bioactive compound may also be useful for treating neurodegenerative diseases like age-related macular degeneration (AMD). Our research focuses on AMD-related pathomechanisms using primary porcine retinal pigment epithelium (RPE) cells in vitro and zebrafish (Danio rerio) models in vivo. We tested the bioactivity of a commercially available fucoidan (FVs) from bladderwrack with regard to pathomechanisms of AMD. We performed multiplex assays, RT-qPCR and fluorescence-based assays for the formation of nitric oxide (DAF-FM assay) and reactive oxygen species (DCF-DA assay) to analyze angiogenesis-related chemokines and pro-inflammatory cytokines as well as protection against oxidative stress and inflammatory insult. Our results showed that FVs significantly reduced the secretion of pro-angiogenic vascular endothelial growth factor A (VEGF-A) and follistatin as well as the pro-inflammatory cytokines interleukin 8 (IL-8) after lipopolysaccharide (LPS) and polyinosinic/polycytidylic acid (PIC) induction. Interleukin 6 (IL-6) was also reduced in the supernatant of the RPE cells. Additionally, in zebrafish, fucoidan decreased the production of NO and ROS. Gene expression of zebrafish embryos revealed anti-inflammatory effects by suppressing pro-inflammatory genes and significantly downregulating, e.g., interleukin 1 beta (IL-1\u03b2). These findings indicate modulation of oxidative stress, inflammatory responses, and VEGF secretion of the used FVs. This study demonstrates that fucoidan possesses AMD-relevant bioactivities in vitro and in vivo, suggesting fucoidan warrants further investigation in AMD-related research and related pathological mechanisms.\n\nID: 42333946\nTitle: Humanin Mitigates A\u03b2-Induced Retinal Pigment Epithelium Injury via AMPK-Beclin1-Dependent Mitophagy.\nAbstract: Amyloid beta (A\u03b2), a key component of drusen in age-related macular degeneration (AMD), induces oxidative stress, mitochondrial dysfunction, and degeneration in the retinal pigment epithelium (RPE), contributing to progressive vision loss in the elderly. We investigated the protective role of Humanin (HN), a mitochondria-derived peptide with known neuroprotective effects in A\u03b2-related neurodegenerative diseases, in retinal pathology induced by subretinal injection of FITC-labeled A\u03b2. HN enhanced the clearance of A\u03b2-accumulated mitochondria in the RPE while preserving retinal function and RPE barrier integrity. In ARPE-19 cells, HN activated AMP-activated protein kinase (AMPK), leading to phosphorylation of ULK1 and Beclin1, which promoted the interaction between Beclin1 and Parkin and their translocation to mitochondria. This process facilitated the removal of A\u03b2-accumulated mitochondria in the RPE. Our results demonstrate that targeting mitophagy in the RPE with HN may offer a promising therapeutic strategy for AMD.\n\nID: 42314860\nTitle: Predicting the progression of proliferative diabetic retinopathy: Pathophysiology, imaging phenotypes, and determinants of disease persistence despite therapy.\nAbstract: Proliferative diabetic retinopathy (PDR) is a leading cause of severe vision loss in working-aged adults and represents the end stage of chronic neurovascular injury in diabetes. Despite advances in screening and treatment, including panretinal photocoagulation (PRP), intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents, and pars plana vitrectomy (PPV), outcomes remain heterogeneous: many eyes stabilise, whereas others progress to vitreous hemorrhage, tractional retinal detachment, or neovascular glaucoma despite apparently adequate therapy. This review synthesizes current knowledge on the pathophysiology, morphological phenotypes and treatment paradigms of PDR, with a specific focus on predictors of onset, progression, and recurrence. PDR is contextualised as a multifactorial neurovascular and inflammatory disease, integrating data on hypoxia-driven angiogenesis, glial activation, microvascular rarefaction, neurodegeneration, and vitreoretinal interface remodeling. Histopathological and multimodal imaging characteristics of neovascular complexes and the vitreoretinal interface are described, highlighting how phenotypes on color fundus photography, widefield fluorescein angiography, optical coherence tomography (OCT), and OCT angiography relate to ischemic burden and clinical behaviour. Systemic, ocular, imaging, biomarker, and genetic factors associated with progression from non-proliferative diabetic retinopathy to PDR and with progression within established PDR after PRP, anti-VEGF therapy, and PPV are critically appraised. Across modalities, younger age, diabetes duration, poor glycemic control, renal disease, extensive non-perfusion, high neovascular burden, complex fibrovascular proliferation, and incomplete or unsustained treatment consistently emerge as determinants of guarded outcomes. Outstanding gaps in mechanistic understanding, risk stratification, regenerative therapy, and implementation are identified, alongside a proposed research agenda aimed at delivering mechanistically grounded risk-prediction tools and disease-modifying interventions for PDR.\n\nID: 42304076\nTitle: Multi-omic analysis of deep learning-derived phenotypes links ophthalmic imaging to cardiovascular and neurological traits.\nAbstract: The eye is a recognized source of biomarkers for cardiovascular and neurodegenerative disease risk. Here we characterize the breadth of these associations and identify biological axes that may mediate them. Using UK Biobank data, we developed a multi-omic analysis pipeline integrating physiological, radiomic, metabolomic and genomic information. We trained retinal adversarial autoencoders to represent optical coherence tomography images and color fundus photographs as 256-dimensional embeddings. Retinal adversarial autoencoder-derived embeddings were associated with a range of cardiovascular and neurodegenerative diseases, including ischemic heart disease, cerebrovascular disease, Parkinson's disease and dementia. Examining associations across diverse omics datasets, we provide evidence linking ophthalmic imaging features to neurological and cardiovascular anatomy and function, lipid metabolism and gene sets associated with neurodegenerative pathology. Collectively, our findings show that ophthalmic features reflect complex, multisystem biological processes and reinforce the role of the eye as a composite indicator of systemic health.\n\nID: 42289610\nTitle: Ultrastructural response of the retinal cells and neurovascular unit to neuroinflammation induced by lipopolysaccharide.\nAbstract: Inflammation within the central nervous system (CNS) plays a pivotal role in neuronal survival and degeneration. Lipopolysaccharide (LPS) is a widely used agent for inducing systemic and localized inflammation in mammals, providing a model for studying neurodegenerative processes. While previous research has documented neuronal loss due to LPS-induced neurodegeneration, the progressive morphological changes in neurons remain insufficiently characterized, particularly in retinal tissues. This study addresses this gap by establishing acute and chronic retinal inflammation models in mice using single and repeated intraperitoneal LPS injections. Through ultrastructural analyses using electron microscopy, we observed significant pathological changes in retinal neurons, glial cells, and blood-retinal barrier (BRB) components. Acute LPS exposure resulted in lipid droplet accumulation and membrane disruption in retinal pigment epithelium (RPE), as well as abnormal neuronal and vascular ultrastructures. Chronic LPS exposure amplified these effects, causing more pronounced damage to neurons and exacerbating BRB dysfunction. This study provides, for the first time, detailed ultrastructural insights into LPS-induced acute and chronic retinal inflammation. These findings advance our understanding of retinal pathology in inflammatory conditions and support the development of novel therapeutic strategies for retinal and CNS neurodegenerative diseases.\n\nID: 42246542\nTitle: Diosgenin Attenuates Photoreceptor Degeneration in an N-Methyl-N-Nitrosourea-Induced Mouse Model of Retinal Degeneration.\nAbstract: Retinitis pigmentosa (RP) is a hereditary retinal disorder distinguished by progressive photoreceptor cell (PRC) loss, in which glial activation can accelerate degeneration. Diosgenin, a natural steroidal sapogenin with potent anti-inflammatory properties, has shown therapeutic potential for ocular and neurodegenerative diseases but has not been explored for retinal degeneration. This study examined the protective role of diosgenin against PRC degeneration and explored potential anti-inflammatory mechanisms in an N-methyl-N-nitrosourea (MNU)-induced mouse model of retinal degeneration. The model was established by intraperitoneal injection of 50 mg/kg MNU, followed by oral gavage of diosgenin/lutein (positive control)/vehicle. The effects of diosgenin on PRC structure, apoptosis, retinal function, and glial activation were evaluated. Network pharmacology and molecular docking were used to investigate potential mechanisms. Diosgenin preserved retinal integrity and function in MNU-induced mice, with relative preservation of the outer nuclear layer thickness and outer segment (OS) length of rods and cones. Disorganization of OS membrane discs and abnormal morphology of organelles were attenuated, while fundus photographs showed fewer lesions. Furthermore, diosgenin mitigated PRC apoptosis and maintained retinal light responses. Mechanistically, diosgenin ameliorated reactive gliosis of M\u00fcller glial cells (MGCs), attenuated the expression levels of inflammatory cytokines and chemokines, and mitigated activation of the IL6ST/JAK2/STAT3 pathway. Diosgenin attenuated PRC degeneration in MNU-induced mice, and one of its mechanisms may involve the attenuation of reactive gliosis in MGCs and inflammatory responses, with possible involvement of the IL6ST/JAK2/STAT3 pathway. Diosgenin may serve as a potential intervention candidate for retinal degenerative diseases, such as RP.\n\nID: 42239431\nTitle: Mesenchymal-derived neural progenitors underlie local insulin production and neuronal transdifferentiation during retina regeneration.\nAbstract: In humans, retinal-neuron death, optic-nerve injuries, and associated neurodegenerative diseases, such as glaucoma and age-related macular degeneration, often lead to permanent vision loss. While the capacity for regeneration is low in the human nervous system, including the retina, some non-mammalian vertebrate species, including zebrafish, are capable of endogenous neuronal regeneration after injury. Unlike mammals, zebrafish do not form a scar that inhibits axonal and neuronal regeneration after injury. Rather, they harbor neural progenitor and stem-cell populations allowing regeneration of entire parts of the nervous system and restoration of tissue integrity and function. In the zebrafish retina, cycling neural progenitor cells of the ciliary marginal zone and quiescent resident neural stem cells (the latter of which are also called M\u00fcller glial cells) participate in neuronal regeneration following different types of injury. In this study, we report the identification of a novel, additional cellular source participating in neuronal regeneration of neurons in the zebrafish retina after genetic ablation of retinal ganglion cells. Before injury, these progenitor cells express molecular markers of neural-crest-cell and/or fibroblast identity, such as sox10, pdgfrb, and eya2, while after neuronal ablation they also express proneural factors including the ascl1a and olig2 genes. Combining genetic ablation of neurons with photoconversion or Cre/Lox-dependent genetic lineage tracing of sox10-expressing cells, we demonstrated that these cells can differentiate into post-mitotic retinal neurons in the ganglion cell layer (GCL) in the absence of cell proliferation. We also showed, surprisingly, that this progenitor population locally produces insulin mRNA, and that insulin signaling is involved in the accumulation of mesenchymal-derived neural progenitors in the GCL and in their subsequent transdifferentiation into RGCs. This work reveals an unexpected and novel cellular mechanism of transdifferentiation, dependent on a neural-crest-derived mesenchymal cell population, participating in neuronal regeneration in the zebrafish retina. The discovery of this plastic cell population could potentially lead to new strategies to promote the formation of new neurons in the mammalian retina.\n\nID: 42217970\nTitle: Optical coherence tomography and OCT-angiography in neurologic and neuro-ophthalmologic diseases: Current applications and future perspectives.\nAbstract: Optical coherence tomography (OCT) and OCT-angiography (OCTA) have emerged as useful tools for noninvasive imaging in the neurologic field. This chapter elucidates their utility in detecting biomarkers for the diagnosis and monitoring of progression and response to treatment in different prevalent neurologic conditions. The retina, an extension of the central nervous system, presents a unique opportunity for monitoring brain pathology due to its accessibility. Through highly resolved scans of the retina and optic nerve, OCT and OCTA facilitate the identification of subtle clinical changes occurring during neuroinflammatory, neurodegenerative, and ischemic processes in disorders like multiple sclerosis, Alzheimer and Parkinson disease, anterior ischemic optic neuropathies, and papilledema. Peripapillary nerve fiber layer and macular internal retinal layer thickness on OCT, and vessel density in the superficial retina on OCTA seem to be the most sensitive parameters in detecting axonal injury and neurodegeneration. These metrics hold promise as surrogate markers for cerebral alterations. While OCT and OCTA show considerable potential, continued research is necessary to validate their reliability and clinical significance, considering potential confounding factors such as concurrent ophthalmic pathologies. Nonetheless, these advancements represent significant progress toward enhancing the diagnosis, management, and prediction of outcomes in various neuro-ophthalmic disorders.\n\nID: 42216554\nTitle: NF-\u03baB Involvement in Glaucoma-Associated Neuroinflammation: Focus on Glial Cells.\nAbstract: Glaucoma is a complex neurodegenerative disease characterized by the progressive loss of retinal ganglion cells (RGCs) and optic nerve damage. Both mechanical and vascular factors are believed to contribute to the etiology of glaucoma. However, the underlying pathogenic mechanisms are not yet fully understood. In this article, although it is a single component of a multifactorial condition, we argue that neuroinflammation is a significant factor in glaucoma pathogenesis. Glaucoma, at present, is recognized as a neurodegenerative disorder sharing common neuroinflammatory mechanisms with classical neurodegenerative diseases. The involvement of classical immune signaling pathways, such as TLRs and NF-\u03baB, as well as proinflammatory cytokines like TNF-\u03b1, aligns glaucoma with other neurodegenerative diseases where inflammation is pivotal (e.g., Parkinson's and Alzheimer's diseases). As such, glaucoma should be considered not only an ocular pressure disorder but also a neurodegenerative condition with a strong immune component. This perspective opens new avenues for novel therapeutic intervention, including the targeting of glial cells or modulators of inflammatory signaling. However, the complexity of microglial phenotypes and the timing of their activation relative to astrocytes remain areas that require further clarification. The current M1/M2 paradigm is acknowledged as overly simplistic, highlighting the need for more refined and nuanced models. Although oxidative stress and other interconnected signaling, such as STAT3, are involved in the pathogenesis of glaucoma, here, we focus on the role of the NF-\u03baB signaling pathway within the glaucomatous condition with a special focus on the main characters fostering the neuroinflammation.\n\nID: 42162725\nTitle: A novel NRF2 activator designed for an ophthalmic solution.\nAbstract: Oxidative stress is a major contributor to retinal degeneration in ocular neurodegenerative diseases, including glaucoma, where the loss of retinal ganglion cells (RGCs) leads to vision loss. The transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) plays pivotal roles in the cellular defense system against oxidative and xenobiotic stress, making NRF2 activation a promising therapeutic target for ocular neurodegenerative disorders. Covalent NRF2 activators have been extensively studied in clinical trials, leading to the approval of two drugs. However, no non-covalent NRF2- Kelch-like ECH-associated protein 1 (KEAP1) protein-protein interaction (PPI) inhibitors are currently in clinical development, despite their potential for selective and reversible KEAP1 inhibition with fewer side effects. In this study, to develop high potency compounds with suitable properties for an eye drop preparation, we modified the structure of known NRF2-KEAP1 PPI inhibitors. The newly identified compound, SLOS-1811-06 tR1, exhibited neuroprotective effects at concentrations \u22650.01\u202fnM in a hypoxia-induced neurodegeneration model using human-induced pluripotent stem cell (hiPSC)-derived RGCs. It showed high aqueous solubility (21.04\u202f\u00b1\u202f0.08\u202fmg/mL), enabling easy formulation as an eye drop. One hour after a single topical dose of a 0.5% SLOS-1811-06 tR1 solution in rabbits, its concentration in the posterior retina/choroid was 4.4\u202f\u00b1\u202f2.7\u202fnM, exceeding the effective level observed in vitro. These findings highlight the potential of SLOS-1811-06 tR1 as a promising topical drug candidate for treating oxidative stress-related glaucoma.\n\nID: 42105166\nTitle: Intriguing roles of M\u00fcller glia: a special emphasis on the development and pathology of M\u00fcller glia cells in the retina.\nAbstract: The aspiration of this review is to discuss the intricate development of M\u00fcller glial cells (MGCs) and their indispensable neuroprotective and regenerative roles, as well as novel avenues of treatment for retinal neurodegenerative diseases. MGCs are the principal radial glial cells of the vertebrate retina, extending from what is composed of a characteristic funnel-shaped morphology spanning throughout the retinal thickness. Their cell bodies are in the inner nuclear layer (INL), and their processes span from the outer limiting membrane to the inner limiting membrane, where they strongly associate with neurons, blood vessels, and the extracellular matrix across all layers of retinal structure. These cells preserve ionic and water homeostasis, control neurotransmitter uptake, and participate in constructing the blood retinal barrier (BRB), as well as deliver crucial metabolic help to neurons by means of the glutamate-glutamine cycle, thus excluding excitotoxic injury. First, we analysed the molecular processes underlying MGCs activation: pro-inflammatory molecules, Reactive oxygen species (ROS), and survival pathways. Special notice was made of changes in gene expression upon activation and the recrudescence of embryonic developmental programs that permit cell-cycle re-entry and retinal regeneration. Systematic searches of Google Scholar and PubMed to find relevant literature. Upon activation, M\u00fcller's glia, a type of retinal support cell, commence the expression of protective genes, such as Zfp36, Mt1, and Slc14a1. Some creatures could regenerate; however, in mammals, this capacity is limited, which is particularly evident in the retina, where, despite the activation of M\u00fcller's glia, full regeneration of damaged photoreceptors is not achieved. MGCs produces retinal progenitors that assist photoreceptors and interneurons while maintaining retinal integrity. MGCs contain progenitor cells that can differentiate into both neurons and other retinal cell types. Molecular targets for retinal therapeutics that utilize MGCs include pathways that regulate inflammation and oxidative stress. M\u00fcller glial cells are essential for maintaining retinal health, safeguarding neurons, and facilitating their regeneration. Targeted molecular therapy is addressed as a promising strategy for retinal neurodegenerative diseases, using their regenerative and protective potential.\n\nID: 42097407\nTitle: Retinal thinning and dorsal visual stream degeneration in neuronal intranuclear inclusion disease: Multimodal MRI/OCT evidence with network and mediation analyses.\nAbstract: To determine whether retinal thinning in neuronal intranuclear inclusion disease (NIID) is associated with multilevel abnormalities across the visual system and with clinical severity. Forty patients with NIID and 40 healthy controls underwent optical coherence tomography to measure peripapillary retinal nerve fiber layer (RNFL) and macular ganglion cell complex (GCC) thickness. Among patients with NIID, 37 underwent structural MRI for quantification of visual-region volumes and 30 underwent resting-state functional MRI for graph-theoretical assessment of visual-network topology. Cognitive function and activities of daily living were evaluated in the NIID cohort. Partial correlation and exploratory mediation analyses were used to examine associations among retinal, neuroimaging, and clinical measures. Patients with NIID showed diffuse thinning of the RNFL and GCC relative to controls, with mean GCC showing the best discrimination between groups. Thinner retinal measures were associated with poorer cognition, worse daily function, and lower mean cortical thickness. Structural MRI identified volume abnormalities in selected visual-system regions, particularly the lateral geniculate nucleus, early visual cortex, and dorsal/parietal regions, and retinal thickness correlated positively with the volumes of several visual regions. Poorer daily function was associated with a lower clustering coefficient of the visual network. Left V3d, the dorsal part of area V3 in the occipital visual cortex, partially mediated the association between retinal thinning and functional impairment. These findings support coordinated retina-brain involvement in NIID across retinal, structural, and network levels, and identify OCT-derived RNFL and GCC thickness as accessible, noninvasive candidate biomarkers of disease severity.\n\nID: 42067699\nTitle: Insulin production in the retina drives autocrine signalling and metabolism reprogramming of the ARPE-19, a retinal pigment epithelium cellular model.\nAbstract: The retinal pigment epithelium (RPE) plays a pivotal role in retinal homeostasis and energy metabolism. A recent study demonstrates that RPE cells release insulin in response to photoreceptor outer segment (POS) phagocytosis and starvation conditions. However, the downstream signalling pathway of this local insulin production has not yet been identified. Therefore, using the ARPE-19 cell line as an in vitro model of human RPE, we have investigated insulin signalling in basal conditions and after rod OS phagocytosis. Our data show that ARPE-19 cells express key pancreatic \u03b2-cell markers, including the transcription factor Pancreatic and Duodenal Homeobox-1 (PDX-1), which translocates to the nucleus in response to phagocytosis, and prohormone convertase 1/3 (PC1/3). In addition, ARPE-19 cells synthesize and secrete insulin already in basal conditions, increasing their release after phagocytosis. The RPE-secreted insulin acts in an autocrine manner, activating the canonical insulin signalling pathway and leading to increased phosphorylation of insulin receptor (IR), insulin receptor substrate-1 (IRS-1), and AKT. An upregulation of the insulin-responsive glucose transporter GLUT4 and increased glucose uptake was also observed, fueling the ARPE-19 cells' oxidative energy metabolism, incrementing the oxidative phosphorylation activity, probably to sustain the high energy demand associated with phagocytosis. At the same time, a decrease in lactate release has been observed. These features may have important implications for understanding retinal energy metabolism and developing novel therapeutic strategies for retinal neurodegenerative diseases.\n\nID: 42060940\nTitle: Retinal nerve fiber layer thickness as a marker of neurodegeneration in epilepsy.\nAbstract: The relationship between epilepsy and neurodegeneration has recently been a subject of debate, particularly regarding whether neurodegeneration is a cause or a consequence of epilepsy. Given that the retina is an extension of the brain and closely connected to it, retinal layer thickness can serve as a biological marker of neurodegeneration. The aim of this work was to measure retinal nerve fiber layer (RNFL) thickness in patients with epilepsy in comparison to healthy controls, and to study the impact of epilepsy duration and seizure frequency on RNFL thickness in those patients. This case-control study was conducted on 53 patients matched clinical definition of epilepsy established by the International League Against Epilepsy (ILAE) 2017, and 50 healthy controls. Cognitive assessment using Montreal cognitive assessment scale (MOCA), and measurement of RNFL thickness using Spectral domain Optical Coherence Tomography (SD-OCT), were done to all included patients and controls. The peripapillary RNFL thickness (superior, inferior & average) were all significantly reduced in both eyes in epileptic patients compared to healthy controls (p-value <0.05). There was a statistically significant difference between epileptic patients and controls regarding MOCA score. There was no statistically significant impact of seizure control, history of status epilepticus, anti-epileptic drugs, seizure frequency, or disease duration on RNFL thickness. There was a statistically significant reduction of the retinal nerve fiber layer thickness in epileptic patients in comparison to healthy controls. Epileptic patients had significant impairment in cognitive functions in comparison to healthy controls.\n\nID: 42036466\nTitle: Multiple attention based deep multimodal fusion network for glaucoma and neurodegenerative disease diagnosis.\nAbstract: Glaucoma and other neurodegenerative diseases involve progressive damage to the optic disc (OD) and can be identified using visual field (VF) tests, colour fundus photographs (CFP) and optical coherence tomography (OCT). However, most studies overlook neurodegenerative cohorts and primarily rely on unimodal approaches, thus failing to leverage advanced deep multimodal fusion techniques to capture modality-specific features and cross-modal interactions. To address the issue, this study aims to design a multi-attention-based deep multimodal network to fuse functional VF with structural CFP and OCT. Using data from 354 eyes with neuropathies (glaucoma, ischaemic optic neuropathy, dementia and Parkinson\u2019s) and 228 normal eyes, we developed novel deep learning techniques for disc segmentation, fovea localisation, disc-fovea angle calculation and alignment, and multi-attention-based deep intermediate multimodal fusion incorporating different combinations of spatial, self- and cross-modal attention mechanisms. The results indicate that our proposed multi-attention-multimodal fusion network (MAM-Fusion-Net) achieved an area under the sensitivity\u2013specificity curve (AUC) of 0.998 (95% CI 0.996\u20131.000) for diagnosing neuropathy versus normal participants and 0.981 (95% CI 0.966\u20130.996) for glaucoma versus non-glaucoma, surpassing state-of-the-art uni- and multi-modal models. This multi-attention-based deep fusion strategy applied to multimodal images shows potential in glaucoma and neurodegenerative disease diagnosis to assist eye care practitioners.\n\nID: 42035927\nTitle: Modulating primary cilia and cilia-dependent Shh signaling increases retinal ganglion cell survival by repressing astrocyte reactivity after optic nerve injury.\nAbstract: The primary cilia and cilia-dependent signaling are key regulators of neurodegenerative diseases. However, their roles in glaucoma and optic nerve injury remain largely unexplored. Here, we reported that astrocyte primary cilia elongated after optic nerve injury, and genetic ablation or shortening of these cilia significantly increased retinal ganglion cell (RGC) survival. Furthermore, single-cell transcriptomic analysis identified astrocytes as the predominant cell type transducing Sonic hedgehog (Shh) signaling. Activation of canonical Shh signaling, which is transduced through primary cilium, downregulated the expression of reactive astrocyte markers, including glial fibrillary acidic protein (GFAP) and complement component 3 (C3). Using adeno-associated virus (AAV)-mediated gene delivery, we further demonstrated that activating astrocytic Shh signaling or shortening their primary cilia promoted RGC survival by suppressing astrocyte reactivity. Together, our findings reveal a critical role for primary cilia and cilia-dependent Shh signaling in modulating astrocyte reactivity to promote RGC survival after optic nerve injury.\n\nID: 42034182\nTitle: Circadian disruption exacerbates oxidative stress and degeneration in the rd10 mouse model of retinitis pigmentosa.\nAbstract: Eye disorders and vision loss have been associated with circadian misalignment and disruption. Nevertheless, growing evidence supports a bidirectional interaction between circadian dysfunction and neurodegeneration, leading to the proposal of circadian disruption as a significant contributing factor to neurodegenerative disorders. This study aimed to assess the impact of disrupting lighting conditions on the circadian rhythmicity and the retinal degenerative process in retinitis pigmentosa mice. Homozygous rd10 mice were maintained under a conventional 12:12\u00a0h LD cycle or under an ultradian 3:3\u00a0h LD cycle from P19 to P27. Spontaneous locomotor activity was continuously recorded during this period. At P27, retinal responsiveness was assessed by electroretinography, retinal thickness was measured by OCT, and the oxidative stress of the retina was evaluated. Locomotor activity recordings showed deterioration in the circadian rhythmicity of LD 3:3 mice, with small circadian amplitude, low phase homogeneity and loss of circadian periodicity. Besides, retinal responsiveness decreased in LD 3:3 mice, with significant differences between the two groups for b-wave amplitudes. Mean retinal thickness also decreased in LD 3:3 mice. Finally, LD 3:3 mice showed increased levels of DHE fluorescence at the photoreceptor plane, indicating increased oxidative stress. This study provides evidence that exposure to LD 3:3 cycles induces circadian disruption, enhances oxidative stress in photoreceptors and exacerbates retinal degeneration in retinitis pigmentosa mice.\n\nID: 42477692\nTitle: Pharmacological manipulation of Sema4D by salvianolic acid A mitigates diabetic retinopathy via inhibiting PlexinB1/RhoA/ROCK/pMLC2 signaling cascade involved in endothelial dysfunction.\nAbstract: Diabetic retinopathy (DR) is a leading cause of blindness. While anti-vascular endothelial growth factor (VEGF) therapy is effective, its utility is limited by variable patient response and the need for frequent injections. Therefore, identifying new therapeutic targets for DR is imperative. Emerging evidence indicates that astrocytes contribute to endothelial dysfunction in DR, suggesting that targeting astrocyte-endothelial cell crosstalk represents a promising therapeutic strategy. To evaluate the therapeutic potential of Salvianolic acid A (Sal A) for DR, elucidate the molecular mechanisms by which it modulates astrocyte-endothelial cell interactions, and develop a liposome-based nanodelivery system to enhance its efficacy. The protective effects and mechanisms of Sal A were systematically investigated using a streptozotocin (STZ)-induced diabetic mouse model, complemented by a suite of in vitro and molecular approaches including co-culture models, transcriptomic analysis, and target validation assays. Retinal vascular structure and barrier function were assessed in vivo via immunofluorescence staining and Evans Blue leakage assays. Endothelial cell behaviors were examined in vitro using wound healing, Transwell migration, tube formation, and spheroid sprouting assays. Transcriptomic profiling was performed by RNA sequencing (RNA-seq). The direct target of Sal A was identified and validated using MS-based drug-affinity responsive target stability (DARTS) screening, cellular thermal shift assay (CETSA), and microscale thermophoresis (MST). Expression of key signaling molecules was measured by western blotting, enzyme-linked immunosorbent assay (ELISA), and quantitative real-time PCR (qRT-PCR). Liposome@Sal A was prepared and characterized for its physicochemical properties (dynamic light scattering, transmission electron microscopy), stability, and therapeutic efficacy in vitro and in vivo. Sal A treatment ameliorated retinal vascular abnormalities in diabetic mice, evidenced by increased VE-cadherin and NG2 expression, decreased \u03b1-smooth muscle actin (\u03b1-SMA) expression, and reduced acellular capillary formation, collectively restoring vascular integrity. Mechanistically, astrocyte-derived soluble Semaphorin 4D (sSema4D) promoted endothelial hyperactivation via the PlexinB1/RhoA/ROCK/pMLC2 signaling cascade. Sal A directly bound to the Arg92 residue of membrane-bound Sema4D on astrocytes, significantly inhibiting sSema4D shedding and its subsequent deleterious effects on endothelial cells. Furthermore, Liposome@Sal A enhanced retinal drug delivery and demonstrated superior therapeutic efficacy compared to free Sal A in diabetic mice. Sal A preserves retinal vascular structure and function in DR by binding to astrocytic Sema4D at Arg92, thereby inhibiting sSema4D shedding and downstream PlexinB1/RhoA/ROCK/pMLC2 signaling, which modulates astrocyte-endothelial cell crosstalk. Liposomal encapsulation significantly potentiates the therapeutic efficacy of Sal A, positioning it as a promising drug candidate for DR treatment.\n\nID: 42476327\nTitle: Exploring shared genetic pathways and gene interplay in major neurodegenerative diseases: a comprehensive review.\nAbstract: Neurodegenerative diseases are progressive disorders that involve the loss and dysfunction of neurons. Alzheimer's disease, Parkinson's disease, Amyotrophic lateral sclerosis, Huntington's disease, Frontotemporal dementia are examples of diseases. While different clinically, these disorders have a common genetic, molecular and cellular basis. This review examines the common genetic pathways, along with the interactions between genes of major neurodegenerative diseases, with a focus on the key genes, such as APOE, SNCA, MAPT, TARDBP, LRRK2 and HTT. The common pathogenic mechanisms considered to play a major role in disease progression include protein misfolding and aggregation, mitochondrial dysfunction, oxidative stress, neuroinflammation, diminished autophagy, and impaired lysosomal function, as well as synaptic degeneration. The review also emphasizes the role of systems biology strategies, such as genome-wide association studies, transcriptomics, proteomics, metabolomics, interactome analysis, and multi-omics integration, to unveiling complex molecular networks in neurodegeneration. Furthermore, the emerging biomarker strategies and therapeutic strategies targeting convergence signaling pathways including NF-\u03baB, PI3K-Akt-mTOR, MAPK and Wnt/\u03b2-catenin are summarized. The common genetic basis and the cross-connecting molecular mechanisms of the various neurodegenerative diseases could help in the discovery of new biomarkers and pan-therapeutic targets. Further advances in molecular genetics, computational biology and precision medicine are needed to enhance early detection and the creation of effective disease-modifying treatments.\n\nID: 42474271\nTitle: VDAC1 O-GlcNAcylation Promotes mtDNA Release and Activates ZBP1-Dependent Neuroinflammation in Diabetic Retinopathy.\nAbstract: The limited efficacy of anti-VEGF therapy in diabetic retinopathy (DR) highlights the importance of nonvascular mechanisms in disease progression. Hyperglycemia is a key driver of neuroinflammation in DR. Hyperglycemia results in VDAC1 O-GlcNAcylation in M\u00fcller glia, leading to mtDNA release and ZBP1 activation, thereby linking metabolic stress to neuroinflammation in DR. Targeting VDAC1-mediated mtDNA release or using vitreous mtDNA as a biomarker may enable earlier diagnosis and novel therapeutic strategies for DR.\n\nID: 42470951\nTitle: Targeting myoferlin by 6-shogaol inhibition regulates hyperglycemia-induced retinal vascular dysfunction.\nAbstract: Hyperglycemic stress induces the dysfunction of endothelial cells, disrupting the microvascular stabilization and remodeling. Our previous study found that Ginger-Coptis formula, a traditional Chinese medicine (TCM) formula, significantly ameliorated diabetic retinopathy, and 6-shogaol was identified as one of the possible contributive compounds. This study aims to investigate the pharmacological effects of 6-shogaol, a key bioactive compound in ginger (Zingiber officinal Roscoe), as a novel inhibitor for myoferlin (MYOF). It also proposes to demonstrate the regulatory effects of 6-shogaol on vascular endothelial growth factor receptor 2 (VEGFR2)/ protein kinase B (Akt)/endothelial nitric oxide synthase (eNOS) signaling in hyperglycemia-induced retinal vasculature as potential molecular mechanisms. The stable isotope labeling by amino acids in cell culture (SILAC) was used to identify the direct binding protein by 6-shogaol under high glucose. The inhibitory activity of 6-shogaol on MYOF was evaluated by cellular assays. Both in vitro assays and streptozotocin-induced diabetic mouse models were used to investigate the effects of 6-shogaol. A structure-activity relationship was conducted to explore the structural basis of 6-shogaol that may contribute to the inhibition of targeted protein function and the angiogenic response to high glucose. The mechanisms were further confirmed by overexpression of targeted proteins in vivo. 6-Shogaol potentially targeted MYOF in retinal endothelial cells and inhibited its function on the regulating the stability and activity of VEGFR2, which reduced the angiogenic responses in the retinal endothelial cells under high glucose. The potential mechanism involved the downregulation of VEGFR2/Akt/eNOS pathway. These effects of 6-shogaol might be associated with structural features such as its \u03b1,\u03b2-unsaturated ketone moiety. 6-Shogaol had the therapeutic potential of alleviating the retinal vascular dysfunction in diabetic mice. Our study demonstrated 6-shogaol as a promising therapeutic candidate and highlighted MYOF as a druggable target for the diabetic retinopathy treatment.\n\nID: 42469634\nTitle: Secretory leukocyte protease inhibitor (SLPI) attenuates TLR4/NF-\u03baB-mediated neuroinflammation in amyotrophic lateral sclerosis: a candidate molecule associated with neuro-pathology.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder driven by neuroinflammation involving activated microglia and astrocytes, which accelerates the loss of motor neurons. While Secretory leukocyte protease inhibitor (SLPI) is known for its immunomodulatory properties, its specific role in ALS pathogenesis has not been fully established. This study aimed to characterize the expression patterns and functional significance of SLPI in ALS models. The study utilized SOD1G93A mice to analyze the spatiotemporal dynamics of SLPI expression in the gastrocnemius muscle, lumbar spinal cord, and serum across different disease stages. In vitro functional assays were conducted using siRNA-mediated knockdown of SLPI in BV2 (microglia), MA (astrocytes), and NSC-34 (motor neurons) cell lines. Additionally, recombinant SLPI protein was applied to LPS-stimulated BV2 cells to investigate its effect on the TLR4/ NF-\u03baB signaling pathway. In SOD1G93A mice, SLPI was significantly upregulated in the gastrocnemius muscle from the pre-symptomatic stage (60 days) through the late stage (130 days). In the lumbar spinal cord, SLPI showed a transient initial increase but declined sharply by the end-stage; a similar significant reduction was observed in late-stage serum levels. In vitro, SLPI knockdown exacerbated pro-inflammatory cytokine production in all three cell types and impaired the antioxidant capacity of NSC-34 motor neurons. Mechanistically, recombinant SLPI attenuated inflammation in BV2 cells by modulating the TLR4/NF-\u03baB pathway. The dynamic changes in SLPI levels suggest its potential relevance as a candidate molecule for disease staging. Meanwhile, its protective effects in regulating inflammation suggest that it could be a promising therapeutic candidate for mitigating ALS-associated neuroinflammation.\n\nID: 42468243\nTitle: Retinal neuroaxonal degeneration in NMOSD vs. MS and unaffected controls: A systematic review and meta-analysis of OCT biomarkers.\nAbstract: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease characterized by optic neuritis and myelitis, often misdiagnosed as multiple sclerosis (MS). Optical coherence tomography (OCT) provides noninvasive quantification of retinal layer damage, offering potential for NMOSD diagnosis and differentiation from MS. Fifty-five articles were included in this meta-analysis. All patients underwent OCT examination, with at least one measurement recorded for retinal assessment. This review is reported according to the Meta-analysis of Observational Studies in Epidemiology guidelines and assessed the risk of bias of the included studies. Subgroup analysis assessed the clinical utility of OCT biomarkers across predefined subgroups. Sensitivity analysis was used to evaluate stability of results. Begg's and Egger's test and funnel plot were applied to assess publication bias. The results showed that the thickness of peripapillary retinal nerve fiber layer (pRNFL) (WMD\u202f=\u202f-17.73, p\u202f<\u202f0.001), macular RNFL (WMD\u202f=\u202f-5.35, p\u202f<\u202f0.001), superior RNFL (RNFL-S) (WMD\u202f=\u202f-32.91, p\u202f<\u202f0.001), inferior RNFL (RNFL-I) (WMD\u202f=\u202f-39.21, p\u202f<\u202f0.001), temporal RNFL (RNFL-T) (WMD\u202f=\u202f-17.74, p\u202f<\u202f0.001), nasal RNFL (RNFL-N) (WMD\u202f=\u202f-13.59, p\u202f<\u202f0.001), superotemporal RNFL (WMD\u202f=\u202f-25.60, p\u202f<\u202f0.001), inferotemporal RNFL (WMD\u202f=\u202f-26.97, p\u202f=\u202f0.001), superonasal RNFL (WMD\u202f=\u202f-19.84, p\u202f<\u202f0.001), inferonasal RNFL (WMD\u202f=\u202f-23.31, p\u202f<\u202f0.001), ganglion cell and inner plexiform layer (GCIPL) (WMD\u202f=\u202f-14.03, p\u202f<\u202f0.001), ganglion cell layer (WMD\u202f=\u202f-9.34, p\u202f<\u202f0.001), inner plexiform layer (WMD\u202f=\u202f-6.02, p\u202f<\u202f0.001), outer nuclear layer (WMD\u202f=\u202f-2.03, p\u202f<\u202f0.001), foveal (WMD\u202f=\u202f-12.95, p\u202f<\u202f0.001) and GCIPL volume (WMD\u202f=\u202f-0.11, p\u202f<\u202f0.001) in NMOSD were significantly thinner than those in the normal population, but no significant changes were found in the outer plexiform layer and photorreceptor layer. On the other hand, compared with MS, NMOSD had significantly thinner pRNFL (WMD\u202f=\u202f-11.68, p\u202f<\u202f0.001), RNFL-S (WMD\u202f=\u202f-18.09, p\u202f=\u202f0.017) /RNFL-I (WMD\u202f=\u202f-21.25, p\u202f=\u202f0.008)/ RNFL-T (WMD\u202f=\u202f-6.47, p\u202f<\u202f0.001)/RNFL-N (WMD\u202f=\u202f-2.38, p\u202f=\u202f0.048) and GCIPL (WMD\u202f=\u202f-4.22, p\u202f<\u202f0.001). Similarly, NMOSD patients had reduced macular volume compared with NC and MS (WMD\u202f=\u202f-0.32, p\u202f<\u202f0.001), with no difference in inner nuclear layer thickness. OCT serves as a validated imaging biomarker for detecting NMOSD-specific intraretinal neurodegeneration, delineating pathological mechanisms and enhancing differential diagnosis, prognostication, and therapeutic monitoring.\n\nID: 42467293\nTitle: Resveratrol and neuroprotection: modulation of cellular dynamics and signaling networks in neurodegenerative diseases.\nAbstract: Progressive loss of neurons, oxidative stress, neuroinflammation, and mitochondrial dysfunction are hallmarks of neurodegenerative diseases (NDs), such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS). Resveratrol, a polyphenolic phytoalexin mainly found in grapes and red wine, is a promising treatment candidate due to its diverse biological effects and neuroprotective properties. This review demonstrates the regulatory effects of resveratrol on cellular signaling pathways linked to NDs and its neuroprotective mechanisms. Resveratrol enhances neuronal survival, boosts mitochondrial biogenesis, and mitigates oxidative stress by affecting key molecular pathways, including SIRT1/AMPK, PI3K/Akt, MAPK, and Nrf2/ARE. The PI3K/Akt and ERK1/2 pathways promote neuronal regeneration by modulating pro-apoptotic and anti-apoptotic factors. Resveratrol inhibits NF-\u03baB, reducing cytokine release and microglial activation, thereby exhibiting anti-inflammatory properties. It improves cognitive function, synaptic plasticity, and neuronal survival. Despite an increasing pharmacological profile, its practical applicability is limited by inadequate bioavailability, rapid metabolism, and restricted brain penetration. This review demonstrates resveratrol's effect on interconnected signaling networks related to neurodegeneration. We critically compare evidence from preclinical and clinical studies, demonstrating both therapeutic potential and translational limitations. Emerging nanotechnology-based delivery strategies are demonstrated to overcome bioavailability and blood-brain barrier penetration challenges. These insights provide a translational perspective for the future development of resveratrol-based interventions in NDs.\n\nID: 42465739\nTitle: Development and efficacy of ex vivo expanded autologous regulatory T cells for the treatment of amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with limited therapeutic options, in which neuroinflammation critically drives disease progression. Regulatory T cells (Tregs) exert potent immunosuppressive and neuroprotective effects, offering great potential for ALS treatment. However, clinical application of Treg therapy is hampered by low peripheral cell abundance and unstable expansion quality. Here, we established and optimized a GMP-grade protocol for sorting and expanding peripheral blood-derived Tregs, and validated cryopreserved apheresis products as feasikble starting materials. Although ALS patient-derived Tregs showed reduced expansion capacity compared with healthy donor counterparts, they maintained comparable purity, stable regulatory phenotypes, and robust immunosuppressive function. Transcriptomic analysis confirmed the lineage fidelity and low pro-inflammatory characteristics of expanded Tregs. Therapeutic efficacy was verified in SOD1G93A ALS and GvHD mouse models with delayed disease progression and relieved inflammation. This study provides standardized GMP manufacturing strategies and solid preclinical evidence to support the ongoing clinical trial (NCT06671236) and facilitate Treg immunotherapy translation for ALS.\n\nID: 42462180\nTitle: Multiplex Panel Detects Glial and Inflammatory Biomarker Signatures in Sporadic and C9orf72-ALS.\nAbstract: CSF proteomics has emerged as a valuable strategy for identifying diagnostic and prognostic biomarkers in amyotrophic lateral sclerosis (ALS). However, the limited availability and volumes of CSF samples restrict the broader clinical application of CSF-based biomarker panels. To address this challenge, we investigated whether the novel nucleic acid-linked immuno-sandwich assay (NULISA) multiplex platform-capable of quantifying multiple neural, glial, and inflammatory markers from minimal biofluid volumes-could validate previously proposed biomarkers and identify additional candidates relevant to ALS. Using this platform, we measured a targeted panel of 131 biomarkers in cohorts of patients with C9orf72-associated ALS, sporadic ALS (sALS), and matched healthy controls. The 6 markers neurofilament heavy chain (NEFH) and neurofilament light chain (NEFL), chitinases-particularly chitotriosidase-1 (CHIT1) and chitinase-3-like protein-1 (CHI3L1), and chemokines CCL2 and CCL3 were significantly elevated in both ALS groups compared with controls. These biomarkers correlated with disease progression and demonstrated strong diagnostic performance when combined into aggregate scores, as reflected by a high area under the receiver operating characteristic curve for ALS. Notably, C9orf72-ALS patients exhibited higher levels of the oxidative stress-related markers PRDX6 and ENO2, compared with sALS patients, suggesting a genotype-specific molecular signature. Overall, our findings support the use of a multiplexed panel of diverse, inflammatory, glial, and neurodegeneration-associated biomarkers as a complementary diagnostic and prognostic tool alongside established measurements of neurofilaments. This approach may enhance biomarker robustness while minimizing CSF volume requirements, thereby improving clinical feasibility in ALS research and care.\n\nID: 42460524\nTitle: Mechanisms and Therapeutic Targeting of the cGAS-STING Pathway in Central Nervous System Disorders.\nAbstract: The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) signaling pathway is a core DNA-sensing axis in innate immunity and has been increasingly implicated in the pathogenesis of multiple Central Nervous System (CNS) disorders. This review summarizes current knowledge of cGAS-STING signaling in CNS disorders and evaluates its therapeutic potential. Relevant studies on cGAS-STING signaling in CNS disorders were collected from PubMed and Web of Science, with emphasis on disease mechanisms, neuroinflammatory regulation, and pathway-targeted therapeutic strategies. In the CNS, cGAS-STING signaling exhibits marked region-, cell-, and pathology-dependent heterogeneity. Aberrant DNA sensing activates this pathway and amplifies neuroinflammation, cellular stress, and tissue injury in Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), ataxia-telangiectasia (A-T), and ischemic and hemorrhagic stroke. Pharmacological inhibition of cGAS, cyclic GMP-AMP (cGAMP), or STING, together with emerging delivery strategies, has shown promise in preclinical models. Clinical translation remains limited by incomplete validation of pathway specificity, limited human evidence, restricted brain delivery, and inconsistent efficacy assessment. The cGAS-STING pathway links aberrant DNA sensing to innate immune activation and CNS pathology. Clarifying its disease-, cell-, and stage-specific roles may support future targeted therapeutic strategies for CNS disorders.\n\nID: 42460327\nTitle: Neurovascular unit uncoupling in diabetic retinopathy: molecular mechanisms and stage-adapted therapeutic strategies.\nAbstract: Diabetic retinopathy (DR) is a major neurovascular complication of diabetes and remains a leading cause of vision loss among working-age adults worldwide. Although DR has traditionally been classified as a microvascular complication, it is now increasingly recognized as a neurovascular degenerative disorder involving coordinated injury to neuronal, glial, vascular, and extracellular matrix components of the retinal neurovascular unit (NVU). The NVU provides the structural and functional basis for coupling neuronal activity to local blood flow and for maintaining retinal immune and barrier homeostasis. In diabetes, chronic hyperglycemia, oxidative stress, inflammation, metabolic dysregulation, impaired vascular endothelial growth factor (VEGF)/angiopoietin-Tie (Ang/Tie) signaling, abnormal intercellular communication, and epigenetic memory progressively disrupt the coordinated interactions among NVU components, leading to neurovascular uncoupling. This concept helps explain why retinal functional abnormalities and neurodegenerative changes may precede clinically visible vascular lesions. In this review, we summarize cell-specific NVU alterations and the molecular mechanisms that drive neurovascular uncoupling in DR. We also discuss how this framework may support earlier diagnosis, mechanism-based phenotyping, and stage-adapted treatment strategies. Established therapies, including anti-vascular endothelial growth factor (anti-VEGF) agents, corticosteroids, and angiopoietin-2 (Ang-2)/Tie-2-directed vascular stabilization, are considered together with investigational approaches targeting oxidative stress, inflammation, neuroprotection, metabolic reprogramming, epigenetic regulation, and drug delivery. Reframing DR as a diabetes-driven disorder of early NVU uncoupling may help shift clinical thinking from late vascular rescue toward mechanism-based neurovascular protection, precision phenotyping, and stage-adapted intervention.\n\nID: 42459857\nTitle: Experimental evidence of electroacupuncture in ALS mouse models: a systematic review and meta-analysis.\nAbstract: This study aimed to systematically evaluate the therapeutic efficacy of electroacupuncture (EA) in amyotrophic lateral sclerosis (ALS) and to elucidate the underlying neurobiological mechanisms by synthesizing preclinical evidence. According to the PICOS principle, relevant studies were searched in the following databases: PubMed, Web of Science, Embase, Cochrane Library, Scopus, and CNKI. Search terms and strategies were determined based on MeSH terms. The methodological quality of the included studies was assessed using the SYRCLE's Risk of Bias tool and the CAMARADES checklist. Meta-analysis was performed using Stata 15.0 and Rstudio software. Seventeen studies involving 372 animals were included. The quality scores of the included studies ranged from 5 to 8, with an average score of 7. The meta-analysis of the primary outcome, the rotarod test score, showed a significant improvement in the EA group compared to the control group [SMD\u202f=\u202f3.31, 95% CI (2.05, 4.57), Z\u202f=\u202f5.151, p\u202f<\u202f0.001], indicating that EA can enhance motor function in ALS mice. Regarding secondary outcomes, EA intervention alleviated neuroinflammation, promoted neuronal survival, improved axonal regeneration inhibition, and stabilized RNA metabolism homeostasis. Consequently, it slowed disease progression, improved motor performance, prolonged survival time, and effectively protected motor neurons at the histopathological level (p\u202f<\u202f0.05). These findings underscore the potential of EA as a promising multimodal therapeutic strategy for ALS. For the heterogeneity observed in the rotarod test, sensitivity analysis, subgroup analysis, and meta-regression did not identify its source. However, potential publication bias was detected, which might contribute to the heterogeneity. The heterogeneity for other outcome measures might originate from differences in stimulation parameters (e.g., waveform), acupoint selection, or treatment duration. This meta-analysis demonstrates that EA confers significant neuroprotective benefits in preclinical ALS models, primarily through multi-target modulation of key pathological processes such as neuroinflammation, aberrant cell death signaling, and RNA metabolism. These preclinical findings underscore the potential of electroacupuncture as a complementary neuroprotective strategy and warrant further investigation in rigorous clinical trials. https://www.crd.york.ac.uk/PROSPERO/view/CRD420251229183.\n\nID: 42459525\nTitle: Imaging biomarkers in neurodegenerative diseases: advances and challenges.\nAbstract: Neurodegenerative diseases (NDDs), including Alzheimer's disease (AD), Parkinson's disease (PD), frontotemporal dementia (FTD), and amyotrophic lateral sclerosis (ALS), represent a major global health burden. Imaging biomarkers have emerged as important tools for improving the diagnosis, monitoring, and biological characterization of neurodegenerative diseases. Structural MRI, diffusion tensor imaging (DTI), functional MRI (fMRI), positron emission tomography (PET), hybrid PET/MRI and molecular imaging have transformed our ability to investigate neurodegeneration in vivo non-invasively. This review highlights updated information on how each imaging modality offers a unique window into different disease pathophysiology including regional atrophy, amyloid-\u03b2, tau, dopaminergic terminal degeneration, synaptic density (SV2A), and neuroinflammation. We also focused on the translational and evidence supporting biomarkers, appropriate use criteria for amyloid and tau PET imaging, and standardized quantification methods such as the Centiloid scale. The growing role of multimodal fusion, where imaging is increasingly integrated with scalable fluid biomarkers to enable \"blood-first\" strategies where high-risk patients are selectively referred to advanced imaging, improving feasibility and equity. Despite tremendous progress, there are still issues with their standardization, sensitivity, specificity, and clinical translation. Moreover, the review emphasizes the frontiers of \u03b1-synuclein and glial state-specific PET ligands, advanced diffusion models, and dynamic connectivity analysis to support precision medicine and mechanism-based trial design for NDDs.\n\nID: 42459363\nTitle: Inhibiting the uPAR/FPR1 interactions reduces blood-retinal barrier breakdown and improves retinal function in a rat model of diabetes.\nAbstract: Diabetic retinopathy (DR) is a leading cause of blindness characterized by early neurovascular damage driven by hyperglycemia-induced mechanisms, including inflammation. The system composed of the urokinase-type plasminogen activator (uPA) and its receptor (uPAR) has previously emerged as a potential regulator of the pro-inflammatory events in DR, possibly through the interaction of uPAR with its lateral partners, such as formyl peptide receptors (FPRs). This study explored whether the inhibition of uPAR/FPR1 crosstalk may reduce early neurovascular alterations in DR by targeting inflammation. To this aim, the new FPR1 antagonist N-19004 was tested in a rat model of streptozotocin-induced diabetes. N-19004 was administered subcutaneously for 7\u202fdays at 1\u202fmonth from diabetes onset. Immunofluorescence, RT-qPCR, Western blot and Evans blue perfusion were performed to evaluate the effects of N-19004 on inflammation, reactive gliosis, blood-retinal barrier (BRB) integrity and apoptosis. In addition, electroretinogram (ERG) was used to assess N-19004 efficacy on retinal function. N-19004 inhibited the activation of inflammation-related transcription factors, including nuclear factor kappa-light-chain-enhancer of activated B cells and signal transducer and activator of transcription 3, leading to reduced interleukin-1\u03b2 and tumor necrosis factor-\u03b1 expression. The attenuation of inflammatory processes resulted in reduced glial activation, as indicated by lower glial fibrillary acidic protein expression and M\u00fcller cell gliosis. The anti-inflammatory activity of N-19004 was accompanied by decreased BRB breakdown, as demonstrated by N-19004-mediated reduction of vascular endothelial growth factor, increased levels of tight junction components and diminished vessel leakage. The amelioration of BRB integrity was associated with reduced activation of caspase 3 and partial preservation of scotopic ERG a- and b-wave amplitudes, thereby improving retinal viability and function in N-19004-treated STZ rats. These results support the possible involvement of uPAR/FPR1 interactions in the regulation of DR-related inflammation and suggest a novel therapeutic target for the management of the early phases of disease.\n\nID: 42458512\nTitle: Targeting astrocyte-mediated neurotoxicity induced by ALS/FTD-associated RNA binding proteins.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are neurodegenerative disorders characterized by reactive astrocytes that contribute to neuronal injury through TAR DNA-binding protein 43 (TDP-43)-or fused in sarcoma (FUS)-driven neuroinflammatory signaling. Dehydrocostus lactone (DHE), a blood-brain barrier-permeable sesquiterpene lactone with established anti-inflammatory activity, represents a promising but unexplored therapeutic candidate for ALS/FTD. The therapeutic effects of DHE were evaluated in primary mouse and human astrocytes expressing ALS/FTD-associated RNA-binding protein pathology, ALS patient-derived fibroblasts, and primary cortical neurons exposed to astrocyte-conditioned medium. Drosophila models expressing mutant FUS or TDP-43 in glial cells were used to assess locomotor performance and survival. Molecular analyses examined nuclear factor kappa B (NF-\u03baB) signaling, nuclear factor erythroid 2-related factor 2 (NRF2)-dependent antioxidant responses, protein aggregation, mitochondrial function, and inflammatory mediator production. Plasma concentrations of inflammatory cytokines and chemokines were measured in patients with sporadic ALS. DHE exerted neuroprotective effects through a dual mechanism involving suppression of NF-\u03baB-dependent inflammatory signaling and activation of NRF2-mediated antioxidant pathways in astrocytes exhibiting FUS or TDP-43 proteinopathy. DHE attenuated astrocyte-mediated neurotoxicity and improved neuronal mitochondrial function in conditioned-medium assays. In addition, DHE reduced pathological FUS accumulation in FUS P525L-expressing astrocytes and in stress-challenged patient-derived fibroblasts. In Drosophila models, DHE significantly improved locomotor function and extended survival. Translationally, the chemokines CXCL10, CCL3, and CCL19 were elevated in plasma from patients with ALS, were induced by FUS or TDP-43 pathology in astrocytes, and were suppressed by DHE treatment, supporting the clinical relevance of the inflammatory pathways targeted by DHE. DHE mitigates astrocyte-driven neurotoxicity associated with ALS/FTD-related RNA-binding protein pathology by suppressing inflammatory signaling and enhancing antioxidant defense mechanisms. The consistent therapeutic effects observed across mouse and human cellular models, patient-derived samples, and in vivo Drosophila models support further investigation of DHE as a potential therapeutic strategy for ALS/FTD and highlight astrocyte-mediated signaling pathways as actionable targets in neurodegenerative disease.\n\nID: 42455475\nTitle: Exosome Biology at the Interface of Neurodegeneration and Therapeutic Innovation.\nAbstract: Neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis, are defined by progressive neuronal loss, protein misfolding, and chronic neuroinflammation, yet effective disease-modifying therapies remain absent. Exosomes have emerged as key mediators of central nervous system communication and are increasingly central to the biology of neurodegeneration. These nanoscale vesicles transport proteins, lipids, and nucleic acids across cellular and anatomical barriers, influencing synaptic function, immune signaling, and metabolic homeostasis. Under pathological conditions, exosomes facilitate the spread of misfolded proteins such as amyloid-\u03b2, p-tau, \u03b1-synuclein, and TDP-43, thereby accelerating network-level degeneration. At the same time, their cargo exhibits disease-specific molecular signatures detectable in peripheral biofluids, supporting their development as minimally invasive biomarkers for early diagnosis and longitudinal monitoring. Advances in exosome engineering further underscore their potential as therapeutic delivery vehicles capable of crossing the blood-brain barrier and targeting pathogenic pathways with RNA-based therapeutics, proteins, or gene-editing systems. Together, these findings position exosomes as pivotal contributors to both the mechanistic progression and translational targeting of neurodegenerative diseases.\n\nID: 42451691\nTitle: Indole-Derived Compounds as Redox-Modulators: Antioxidant Mechanisms in Neuronal Protection.\nAbstract: Neurodegenerative diseases, such as Alzheimer's, Parkinson's, and Amyotrophic lateral sclerosis, are distinguished by progressive neuronal dysfunction caused primarily by oxidative stress, mitochondrial impairment, neuroinflammation, and redox imbalance. Growing evidence suggests that indole-derived compounds have significant neuroprotective potential due to their antioxidant, anti-inflammatory, and redox-modulating properties. This review summarizes the structural and biological significance of indole scaffolds, focusing on the mechanisms by which natural, endogenous, microbiota-derived, and synthetic indole compounds protect neuronal networks. Indole-3-carbinol, 3,3'-diindolylmethane, indole-3-propionic acid, and melatonin are major indole derivatives that control important neuroprotective pathways like Nrf2/ARE signaling, mitochondrial bioenergetics, neurotrophic factor expression, apoptotic regulation, and suppression of proinflammatory mediators. These compounds also maintain synaptic plasticity, reduce reactive oxygen species production, and improve neuronal survival in neurodegenerative disease models. Additionally, updated information from translational and clinical research indicates that indole-based compounds may have promising therapeutic applications; however, obstacles like low bioavailability, metabolic instability, and blood-brain barrier penetration continue to be major obstacles to clinical application. Development in nanoparticle delivery systems, microbiome-targeted interventions, and rational structural optimization may improve therapeutic efficacy and translational potential. Overall, indole-derived compounds are a versatile class of redox modulators with potential applications in the prevention and treatment of neurodegenerative diseases via integrated antioxidant and neuroprotective mechanisms.\n\nID: 42451086\nTitle: Vitamin D Signaling in Neurodegenerative Disorders: Mechanisms, Therapeutic Potential, and Clinical Implications.\nAbstract: Vitamin D has long been recognized for its role in calcium homeostasis and bone metabolism; however, it is now emerging as an important regulator of central nervous system (CNS) function. Recent evidence suggests that vitamin D signaling contributes to the pathogenesis and progression of several neurodegenerative disorders. Vitamin D exerts neuroprotective effects through multiple mechanisms, including regulation of calcium homeostasis, modulation of immune responses, reduction in oxidative stress, stimulation of neurotrophic factors, and maintenance of blood-brain barrier (BBB) integrity. Vitamin D receptors and metabolizing enzymes are widely distributed across several brain regions, highlighting their direct involvement in neuronal function. This review summarizes the biosynthesis, metabolism, and signaling pathways of vitamin D. It explores its role in neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), stroke, and traumatic brain injury (TBI). Evidence from experimental and clinical studies indicates that vitamin D deficiency is associated with an increased risk and severity of these conditions, while supplementation may provide therapeutic benefits.\n\nID: 42450002\nTitle: Proteasome Dysfunction and Aggregation-Prone Proteins in Neurodegenerative Diseases: From Mechanisms to Therapeutic Opportunities.\nAbstract: Neurodegenerative diseases are characterized by the accumulation of misfolded and aggregation-prone proteins, reflecting a failure of proteostasis. The ubiquitin-proteasome system (UPS), a major pathway for selective intracellular protein degradation, is essential for maintaining neuronal protein homeostasis. Proteasome dysfunction has been implicated in several major neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and Huntington's disease (HD), although its extent and mechanisms vary across disease contexts. In this review, we examine current evidence for proteasome dysfunction in neurodegeneration and discuss how disease-associated proteins impair proteasome function through direct inhibition, defective substrate processing, and sequestration into protein aggregates. We also address the contribution of oxidative stress, neuroinflammation, and aging to proteasome dysregulation. Finally, we highlight emerging therapeutic strategies aimed at restoring proteasome function, including pharmacological activation, modulation of proteasome assembly and stability, and targeted protein degradation approaches. Understanding the context-dependent nature of proteasome dysfunction will be important for developing effective proteostasis-based therapies.\n\nID: 42449449\nTitle: Quantitative evaluation of pigment epithelial encapsulation using polarization-sensitive optical coherence tomography after anti-VEGF therapy for myopic choroidal neovascularization.\nAbstract: We aimed to investigate the association between post-treatment changes in polarimetric entropy (PE), which is a noninvasive surrogate marker of structural heterogeneity associated with pigment epithelial remodeling and measured by polarization-sensitive optical coherence tomography (PS-OCT), and the need for multiple anti-vascular endothelial growth factor (VEGF)-injections in myopic choroidal neovascularization (mCNV). We retrospectively analyzed 11 eyes that received intra-vitreal anti-VEGF injections for treatment-na\u00efve mCNV. Based on treatment response during the first 3 months, eyes were categorized into the single-injection (n\u2009=\u20099) and multiple-injection (n\u2009=\u20092) groups. PS-OCT en face PE maps (6\u2009\u00d7\u20096\u00a0mm) were obtained at baseline and 3 months after treatment, with the analysis area manually centered over the CNV using a 3-mm Early Treatment Diabetic Retinopathy Study (ETDRS) grid. PE values were extracted from the central 1-mm circle (CNV core) and surrounding 1-3-mm annulus (periphery), and the differences before and after treatment were calculated. Intergroup comparisons were conducted using Wilcoxon rank-sum test. PE within the CNV core increased after treatment (p\u2009=\u20090.0037). The multiple-injection group showed a greater PE increase than the single-injection group (p\u2009=\u20090.0347), although this finding should be interpreted cautiously given the small and imbalanced sample size. Exploratory analysis suggested a positive association between the magnitude of PE change in the CNV core and injection number during the 3-month period. High post-treatment entropy may reflect structural heterogeneity associated with pigment epithelial remodeling during the early healing phase. These findings suggest that PS-OCT entropy imaging may serve as a retrospective indicator of tissue response rather than a predictive biomarker in the present dataset. Given the very small and imbalanced sample size, the results should be interpreted as exploratory and hypothesis-generating.\n\nID: 42448407\nTitle: Small molecular therapeutic targets for neurodegenerative diseases.\nAbstract: Neurodegenerative diseases such as Alzheimer's, Parkinson's, Huntington's, and amyotrophic lateral sclerosis disease are characterized by progressive neuronal loss, protein aggregation, and synaptic dysfunction. These diseases share common pathological mechanisms including oxidative stress, mitochondrial impairment, chronic neuroinflammation, protein misfolding, and epigenetic dysregulation. Current therapies offer only symptomatic relief and fail to halt disease progression. Recent advances in transcriptomics and proteomics have enabled the identification of shared molecular pathways and druggable targets across multiple neurodegenerative diseases. The key targets, such as BDNF-TrkB, TREM2, SIRT1, PINK1-Parkin, GSK-3\u03b2, NLRP3, and mTOR have shown promise in preclinical models, offering opportunities for broad-spectrum therapeutic development. Importantly, blood-brain barrier disruption and neuroinflammatory crosstalk exacerbate disease pathology and hinder drug delivery. Innovative strategies involving nanocarriers, gene therapy, and epigenetic modulation are emerging to overcome these barriers. This review highlights the convergence of disease mechanisms, discusses common molecular signatures and therapeutic vulnerabilities, and explores novel small molecular interventions targeting shared pathways mainly in AD and PD. A deeper understanding of aging-associated molecular dysfunction is essential to design sustainable, disease-modifying therapeutics with cross-disease relevance.\n\nID: 42442908\nTitle: Role of ESCRT pathway and autophagy in neurodegenerative diseases.\nAbstract: Neurodegenerative diseases are characterized by progressive neuronal dysfunction and loss resulting from impaired proteostasis and vesicular trafficking. Neurons are particularly vulnerable to these processes due to their post-mitotic nature and complex architecture. Autophagy and the endolysosomal system constitute the primary degradative pathways responsible for maintaining neuronal homeostasis. However, increasing evidence indicates that their effective function critically depends on coordination with the endosomal sorting complexes required for transport (ESCRT). Beyond their canonical role in multivesicular body biogenesis and membrane scission, ESCRT components are now recognized as essential regulators of autophagosome closure, amphisome formation, autophagosome-lysosome fusion, and endolysosomal membrane repair. Disruption of this ESCRT-autophagy interface has emerged as a common pathological feature across major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis/frontotemporal dementia. This review synthesizes evidence from genetic, biochemical, and neuropathological studies to highlight shared molecular nodes, such as ESCRT-III components, the VPS4 ATPase, the adaptor protein ALIX, and late endosomal regulators, including Rab7, that couple membrane remodeling to autophagic flux. Failure of these regulatory checkpoints destabilizes endolysosomal integrity, arrests autophagic maturation, and promotes the accumulation of toxic protein species, thereby driving progressive neuronal degeneration. By framing neurodegeneration through the lens of ESCRT-autophagy coupling failure, this review provides a unified mechanistic perspective that links diverse pathogenic proteins to shared cellular vulnerabilities and identifies ESCRT-mediated membrane dynamics as a critical determinant of neuronal survival.\n\nID: 42439604\nTitle: Neurodegeneration in Glaucoma: Microstructural Magnetic Resonance Imaging Evidence Within and Beyond the Visual Pathway.\nAbstract: To investigate structural and microstructural brain changes in glaucoma using multimodal magnetic resonance imaging across primary, secondary, and higher-order visual brain regions, and their associations with glaucoma diagnosis, optical coherence tomography-derived retinal nerve fiber layer (RNFL) thickness, ganglion cell layer (GCL) thickness, and/or IOP. From the UK Biobank, we identified glaucoma cases (n = 1465) and 10-fold age- and sex-matched controls (n = 14,650). Magnetic resonance imaging modalities comprised T1-weighted structural, diffusion tensor imaging, and neurite orientation dispersion and density imaging. Associations with glaucoma status and ophthalmic measures (RNFL, GCL, and IOP) were assessed using regression models adjusted for age, sex, polygenic risk score, and Townsend Deprivation Index, with false discovery rate correction. Glaucoma was associated with reduced gray matter volume in primary visual regions (lateral geniculate nucleus, optic chiasm, intracalcarine cortex, and occipital pole) and diffusion tensor imaging/neurite orientation dispersion and density imaging abnormalities in the posterior thalamic radiation (all P < 0.001). Glaucoma was also associated with secondary regions (lateral occipital cortex, lingual gyrus, and occipital fusiform gyrus) and microstructural changes in the inferior fronto-occipital and inferior longitudinal fasciculus (all P < 0.001). Higher-order and supporting regions were also associated with glaucoma, including the right putamen and paracingulate gyrus (P < 0.05). The RNFL (P < 0.05) and GCL (P < 0.01) correlated linearly with most primary visual regions, whereas the IOP showed no significant associations. Glaucoma is associated with structural and microstructural brain changes beyond the eye to primary, secondary, and higher-order brain regions. These changes correlate with RNFL and GCL thinning but not IOP. Involvement of the occipital pole is consistent with the plausibility of trans-synaptic degeneration in glaucoma.\n\nID: 42434808\nTitle: Brain targeting and trafficking of extracellular vesicles in central nervous system diseases: a therapeutic roadmap.\nAbstract: Extracellular vesicles (EVs) mediate intercellular signaling in the central nervous system (CNS) by transferring lipids, proteins, and nucleic acids among neurons, glia, endothelium, and immune cells. Brain targeting depends on a linked sequence: EV ligands and adsorbed protein coronas engage receptor modules, select endocytic routes, determine intracellular fate, and define the therapeutic readouts. These fates include lysosomal degradation, recycling, rare cytosolic delivery, or transport across the blood-brain barrier (BBB). In disease, the same pathways can disseminate proteopathic seeds and amplify neuroinflammation. Heparan sulfate proteoglycans (HSPGs) and LDL receptor family members, including low-density lipoprotein receptor-related protein 1 (LRP1), regulate tau, \u03b1-synuclein, and amyloid-\u03b2 handling. Phosphatidylserine readers and complement shape myeloid sink capture and inflammatory output. Integrin, tetraspanin, and ICAM-1 nanoclusters influence avidity, organotropism, and immune suppression. At the BBB, endothelial HSPGs, LRP1, and transferrin receptor (TfR) support receptor-mediated uptake, motivating engineered ligands such as rabies virus glycoprotein-derived peptides, Angiopep-2, and TfR binders. However, endosomal escape remains a major kinetic barrier to nucleic acid delivery. We synthesize these principles across Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, glioblastoma, and demyelinating disease, and outline design and assay standards needed to translate EV biology into safe, manufacturable CNS therapeutics.\n\nID: 42430091\nTitle: The Role of PGC-1\u03b1 in Neurodegenerative Diseases: Molecular Mechanisms, Translational Challenges, and Therapeutic Potential.\nAbstract: Neurodegenerative diseases (NDDs) are progressive disorders in which mitochondrial dysfunction, oxidative stress, proteostasis failure, neuroinflammation, and synaptic damage progressively interact to drive neuronal vulnerability. Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1\u03b1) links metabolic adaptation to stress-response pathways that are repeatedly disrupted in Alzheimer's disease, Parkinson's disease, Huntington's disease, polyglutamine (PolyQ) disorders, and amyotrophic lateral sclerosis. Rather than providing only an updated catalogue of studies, this review organizes the evidence into a cross-disease rheostat framework that explains why PGC-1\u03b1 modulation is protective in some settings but incomplete or maladaptive in others. Current findings indicate that PGC-1\u03b1 supports mitochondrial biogenesis, oxidative phosphorylation, antioxidant defense, mitophagy, autophagy, protein quality control, and inflammatory balance. However, its effects are highly context dependent. In several models, restoration of PGC-1\u03b1-related signaling improves mitochondrial function and reduces neuronal injury, whereas broad, sustained, or cell-inappropriate activation may produce limited benefit or undesirable outcomes. These observations suggest that PGC-1\u03b1 is not a simple neuroprotective switch, but a flexible regulatory hub whose therapeutic value depends on cell type, isoform profile, disease stage, and activation level. Emerging strategies, including small-molecule modulators, gene delivery, antisense-based approaches, nanoparticle systems, and exercise-related interventions, remain largely preclinical and face major barriers related to CNS delivery, pathway selectivity, dose and cell-type control, peripheral safety, and validated target-engagement biomarkers. Nevertheless, clinical translation requires stronger causal validation, reliable target-engagement biomarkers, selective delivery methods, and long-term safety assessment. Future research should focus on precision-based modulation of PGC-1\u03b1 to determine when and how this pathway can be safely used for disease modification. Such a careful approach may help transform PGC-1\u03b1 from a broad experimental target into a clinically relevant strategy for well-defined neurodegenerative phenotypes.\n\nID: 42428879\nTitle: From Air to Brain: Environmental Nanoparticles as Modifiable Risk Factors for Neurodevelopmental, Neurodegenerative, and Mental Disorders.\nAbstract: Ultrafine particles (\u2264100 nm) and other environmental nanoparticles have emerged as biologically active pollutants that can cross biological barriers, including the blood-brain barrier and the placenta. Growing evidence implicates ultrafine particles in a wide range of neuropsychiatric conditions, yet their effects remain poorly integrated into clinical and public health frameworks. In this review, we distinguish between size-defined ultrafine particles (UFPs, \u2264100 nm), composition-defined environmental nanoparticles originating from combustion and secondary formation processes, and engineered nanomaterials (ENPs), which differ in physicochemical properties, exposure scenarios, and regulatory status. This narrative systematic review synthesizes findings from human and experimental studies on the neuropsychiatric and neurodevelopmental effects of environmental nanopollutants. A structured search was conducted in PubMed, Web of Science, Scopus, and Google Scholar up to November 2025, following explicit inclusion and exclusion criteria. Eligible studies included peer-reviewed human and animal research assessing mental health or neurological outcomes of nanopollutant exposure. Epidemiological studies\ue5f8primarily involving traffic-related air pollution and mixed combustion-derived ultrafine particle exposures\ue5f8suggest associations with increased risk of cognitive impairment, autism spectrum disorder, depression, schizophrenia, and neurodegenerative diseases, including Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis. Prenatal and early life exposures were linked to cortical thinning, altered neurodevelopmental trajectories, and early proteinopathies. Underlying mechanisms include neuroinflammation, oxidative stress, and protein aggregation. Despite methodological heterogeneity, the evidence supports the urgent need for regulation and prevention. Environmental nanopollutants constitute an under-recognized, modifiable risk factor for neuropsychiatric and neurodegenerative conditions. A paradigm shift is needed to incorporate environmental exposure history into mental health research, risk assessment, and prevention strategies. Regulatory action targeting nanopollutant emission and exposure, particularly in vulnerable populations, is critical to mitigating long-term neurological consequences.\n\nID: 42426919\nTitle: Effectiveness and safety of intravitreal faricimab for macular oedema secondary to retinal vein occlusion: a systematic review and meta-analysis.\nAbstract: Faricimab is a bispecific monoclonal antibody targeting both vascular endothelial growth factor A and angiopoietin-2, approved for macular oedema secondary to retinal vein occlusion in 2023. The phase III BALATON and COMINO trials demonstrated non-inferiority to aflibercept at week 24, and several real-world cohorts have subsequently emerged. The aim of this systematic review and meta-analysis was to estimate the pooled effect of faricimab on visual acuity, treatment burden, anatomical outcomes, and safety in this indication. PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials were systematically searched from inception to 1 May 2026 for studies reporting outcomes following intravitreal faricimab. Risk of bias was assessed in duplicate using the Cochrane Risk of Bias 2 tool for the randomised evidence and the Risk Of Bias In Non-randomised Studies of Interventions tool for the observational evidence, with single-arm cohorts evaluated as pre-post comparisons. The primary visual acuity outcome was pooled using random-effects meta-analysis with Hartung-Knapp-Sidik-Jonkman adjustment, stratified by treatment status, while outcomes precluded from pooling by methodological heterogeneity were synthesised narratively. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation framework. Ten studies comprising 1,620 eyes met eligibility criteria, including the BALATON and COMINO randomised controlled trials and nine non-randomised cohorts. The pooled mean change in best-corrected visual acuity at approximately 6 months was +\u200916.89 Early Treatment Diabetic Retinopathy Study letters (95% confidence interval 16.05 to 17.72) in treatment-na\u00efve eyes and +\u20098.73 letters (95% confidence interval 4.75 to 12.71) in refractory switch cohorts, with negligible between-study heterogeneity in both analyses. Narrative synthesis was consistent with treatment interval extension following initiation of or switch to faricimab, statistically significant reductions in central retinal thickness across studies, and a short-term safety profile without identified retinal vasculitis events. The synthesis is consistent with intravitreal faricimab use being associated with visual and anatomical improvement in macular oedema secondary to retinal vein occlusion, with the treatment-na\u00efve pooled estimate primarily reflecting registration trial data and the switch cohort estimate characterising refractory phenotypes.\n\nID: 42425169\nTitle: Sex-associated neuroinflammatory and astrocytic responses in amyotrophic lateral sclerosis: evidence from clinical cohorts and a TDP-43 N390D mouse model.\nAbstract: Sex differences are increasingly recognized as important modifiers of neuroimmune processes in neurodegenerative disorders. However, the sex-associated clinical phenotypes and underlying neuroinflammatory mechanisms in amyotrophic lateral sclerosis (ALS) remain poorly understood. This study integrated multimodal clinical assessments, cerebrospinal fluid (CSF) neuroimmune biomarkers, neuroimaging-based glymphatic metrics, and complementary animal analyses to characterize shared and sex-associated alterations in male and female ALS patients. Two independent cohorts including 158 newly diagnosed ALS patients and 112 healthy controls (HCs) underwent evaluations of motor function, cognition, sleep disturbances, and emotional symptoms. Glymphatic function was assessed using choroid plexus volume (CPV), diffusion-derived analysis along the perivascular space (ALPS) index, and white-matter free-water (FW) fraction. In the original cohort, 12 CSF biomarkers spanning astrocytic activation, neuroinflammation, TDP-43 pathology, synaptic dysfunction, and axonal injury were quantified, and glial fibrillary acidic protein (GFAP), interleukin-6 (IL-6), and interleukin-18 (IL-18) were further examined in an independent verification cohort. Complementary neuroimmune alterations were further examined in TDP-43 N390D knock-in mice using ELISA and immunofluorescence. Male ALS patients showed markedly elevated CSF GFAP, IL-6, and IL-18 compared with female ALS patients and HCs after false discovery rate correction (q\u00a0<\u00a00.05). Female ALS patients exhibited increased CSF IL-6 versus HCs, whereas GFAP and IL-18 levels were unchanged. Female ALS patients also demonstrated more severe depressive symptoms and post-traumatic stress disorder than male ALS patients and HCs (p\u00a0<\u00a00.05). Both sexes displayed glymphatic impairment characterized by increased CPV and FW and reduced ALPS index, as well as pronounced sleep disturbances relative to HCs (all p\u00a0<\u00a00.05), with no clear sex-related differences. Complementary animal data showed that, at a fixed chronological age, male TDP-43 N390D mice exhibited more severe motor impairment accompanied by higher brain levels of GFAP, IL-6, and IL-18 and more prominent astrocyte-associated IL-6 and IL-18 signals than female mutant mice. Although microglial activation was also observed in TDP-43 N390D mice, no clear sex-related difference was detected at the sampled age. This multimodal clinical-translational study reveals sex-associated neuroinflammatory heterogeneity in ALS. Male patients exhibit a more pronounced GFAP-, IL-6-, and IL-18-related inflammatory profile, whereas female patients display more prominent affective disturbances. Glymphatic dysfunction and sleep impairment emerge as common pathological pathways across sexes. These findings highlight sex as a crucial biological variable shaping ALS heterogeneity and underscore the importance of incorporating sex-stratified analyses in future ALS neuroimmune research and clinical trials.\n\nID: 42419491\nTitle: The autophagy-senescence-inflammasome axis: A novel triad in neurodegenerative diseases?\nAbstract: Chronic neuroinflammation is a defining feature of brain ageing and neurodegenerative disorders, yet the molecular mechanisms responsible for its persistence remain incompletely understood. Although autophagy dysfunction, glial senescence, and inflammasome activation are well-established contributors to progressive neurodegeneration, these processes are often analysed independently or through pairwise interactions, leaving their collective contribution to persistent neuroinflammation and disease progression insufficiently defined. Here, we synthesise emerging evidence supporting an integrated 'Autophagy-Senescence-Inflammasome (ASI) axis', in which reciprocal interactions among impaired autophagy, senescent glia, and inflammasome signalling establish a self-sustaining cycle of neuroinflammation. We discuss how defective autophagy promotes mitochondrial dysfunction, oxidative stress, and danger signalling, while senescent astrocytes and microglia amplify inflammatory responses through the senescence-associated secretory phenotype (SASP). These intertwined processes converge on chronic inflammasome activation, with mitochondrial dysfunction emerging as a central mechanistic hub. Evidence across Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, stroke, and chronic neuropathic pain highlight the broad relevance of this pathological network. We further analyse current therapeutic strategies targeting autophagy, senescence, and inflammasome pathways, emphasising the limitations of single-target approaches and the potential of multi-target interventions. By integrating these processes into a unified framework, this review provides new insights into the possible molecular mechanisms underlying neuroinflammaging and identifies the 'ASI axis' as a promising target for neurodegenerative disease-modifying therapies.\n\nID: 42415469\nTitle: Proteomic Profile Analysis of Plasma and Aqueous Humor from Glaucoma and Nonglaucomatous Patients.\nAbstract: Glaucoma, a multifactorial ocular neuropathy, can lead to irreversible vision loss. Diagnosis involves assessing optic cupping (increased cup-to-disc ratios) and structural changes (like retinal nerve fiber layer thinning) through clinical imaging. Elevated intraocular pressure (IOP) is commonly associated with glaucoma but is not universally present. However, understanding disease progression is hindered by limited access to donor ocular tissue and consistent clinical data. We hypothesized that the proteomes of aqueous humor (AH) and plasma may be altered in disease and correlate with clinical parameters such as IOP and cup-to-disc ratios. AH and plasma samples were collected from 36 glaucoma patients (17 male, 19 female) and 35 nonglaucomatous control patients (16 male, 19 female) undergoing cataract surgery. Protein profiles was compared using the SOMAscan\u00ae assay system for proteome profiling. From glaucomatous donors, correlations between IOP and cup-to-disc ratios to proteome differences were determined. Overall proteomics profiles between both AH and plasma were compared by combining all samples (glaucoma and nonglaucoma) and then performing correlation analyses. This study revealed similar protein abundance in the two biological fluids. Additionally, it identified different abundance of proteins in plasma and AH between glaucoma and nonglaucoma samples. The differential proteins identified were involved in pathways related to vascular integrity, inflammation, immune response, cell adhesion, and complement activation. Generally, glaucomatous AH showed higher protein levels. Neurofilament light chain protein correlated with elevated IOP and inflammatory markers but not with cup-to-disc ratio. Together, our data demonstrate that the proteins identified in this study from glaucomatous donors correspond to markers of neurodegeneration and those that may inhibit cell proliferation or disrupt vascular integrity.\n\nID: 42474734\nTitle: Use of blood-based neurofilament light chain as an endpoint in clinical trials of neurodegenerative conditions: a scoping review.\nAbstract: Neurofilament light chain (NfL) is a structural axonal protein measurable in CSF and blood, increasingly investigated as a biomarker of neuroaxonal injury in clinical and research contexts. This review aims to explore the use of blood-based NfL as an endpoint in clinical trials of neurodegenerative conditions. A database search of MEDLINE and EMBASE was conducted to identify interventional clinical trials and/or related post hoc analyses for neurodegenerative diseases, published between 2013 and 2024 that reported the use of serum or plasma NfL as an endpoint. Additional studies from reference lists of included trials were manually considered for inclusion where relevant. Data were charted descriptively by disease type and summarised. 49 studies were included, 29 in multiple sclerosis (MS), eight in amyotrophic lateral sclerosis (ALS), six in Alzheimer's disease (AD), and six in other diseases. Across studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response. However, several studies demonstrated a lack of concordance between change in NfL and in clinical outcomes, some of which may be related to the non-disease-modifying mechanisms of the interventions studied. This necessitates careful consideration when applying blood-based NfL as a biomarker endpoint for studies involving such interventions. Blood NfL is a promising biomarker with potential utility as a surrogate endpoint in neurological clinical trials, particularly for diseases with active axonal injury. Further validation, particularly around disease- and intervention-specific interpretation, is needed before blood NfL can be incorporated more routinely as a clinical endpoint.\n\nID: 42460325\nTitle: Deep learning-derived retinal biomarker associated with diabetes-related amputation in type 2 diabetes.\nAbstract: Diabetic foot (DF)-related amputation remains a major cause of morbidity in patients with type 2 diabetes, yet biomarkers associated with amputation risk remain limited. We aimed to assess the independent association between a deep learning (DL)-derived retinal biomarker using coronary artery calcification (Dr. Noon CVD) and DF-related amputation in patients with type 2 diabetes. This retrospective observational study conducted in a university hospital in South Korea included 392 individuals with type 2 diabetes receiving ophthalmic care (79 with DF-related amputation and 313 without). Participants were randomly split into training (70%) and validation (30%) sets. Model performance in relation to DF-related amputation was assessed using area under the receiver operating characteristic curve (AUC), continuous net reclassification index (cNRI), and integrated discrimination improvement (IDI). Prespecified rule-out (sensitivity \u22650.85) and rule-in (specificity \u22650.90) thresholds were also applied. Adding the retinal biomarker to a basic clinical model showed incremental association with DF-related amputation in the validation set (AUC 0.146, 95% CI: 0.046-0.249; cNRI 0.629, 95% CI: 0.184-1.027; IDI 0.062, 95% CI: 0.012-0.110). The full model achieved an AUC of 0.791, and the association remained consistent across sensitivity analyses using DF risk score derived from the external dataset. Under a 27% amputation prevalence (based on the reported prevalence of amputation among patients with diabetic foot), sensitivity was 87.5% with a negative predictive value of 92.6% at the rule-out cutoff; specificity was 90.4% with a positive predictive value of 56.3% at the rule-in cutoff. A DL-derived retinal biomarker shows meaningful association with DF-related amputation beyond conventional diabetes variables.\n\nID: 42447123\nTitle: Neuromuscular ultrasound as a biomarker in the SOD1 mouse model of amyotrophic lateral sclerosis.\nAbstract: A progression marker that indicates early disease-related changes and treatment responses in the to date incurable neurodegenerative disease amyotrophic lateral sclerosis (ALS) is highly desirable. Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies.\n\nID: 42442374\nTitle: Multidomain lifestyle intervention for the prevention of cognitive decline in at-risk older adults in Latin America (LatAm-FINGERS): a single-blind, multicentre, randomised controlled trial.\nAbstract: Latin America faces a high dementia burden, with increased prevalence of factors associated with cognitive decline. Multidomain lifestyle interventions might delay cognitive decline, but populations from Latin America remain under-represented in dementia prevention trials. We aimed to investigate the feasibility of a culturally adapted, multidomain, systematic lifestyle intervention and investigate its effects on global cognitive function in at-risk older adults (aged 60-77 years). The LatAm-FINGERS Initiative for Cognitive Change (hereafter referred to as LatAm-FINGERS) was a single-blind, multicentre, randomised clinical trial conducted in 11 Latin American countries (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Peru, and Uruguay). Individuals aged 60-77 years with high risk of dementia (cardiovascular risk factors, ageing, and dementia risk score \u22656), and suboptimal cognitive performance were randomly assigned (1:1) to receive either a 2-year systematic lifestyle intervention (SLI group) or a flexible lifestyle intervention (FLI group). Randomisation was stratified by the study centre to ensure balance and implemented using permuted blocks of eight. Participants and intervention staff were not masked to group assignment, but individuals who assessed outcomes were masked throughout the trial. The SLI provided structured multidomain lifestyle interventions with supervised support and monitoring; FLI offered health advice. Primary outcomes were trial feasibility (evaluated using selected RE-AIM measures: Reach, Implementation, and Maintenance) and the intervention's effects on global cognitive composite trajectories over 2 years (change in the global cognitive composite score over 2 years). This trial is registered at ClinicalTrials.gov (NCT06492967) and has been completed. Participants were enrolled between Oct 27, 2021, and July 7, 2023; the last participant completed follow-up on Nov 7, 2025. Among 1719 assessed, 1065 participants included in the analytic sample were randomly assigned to the SLI group (n=539) or the FLI group (n=526). Mean age was 67\u00b75 years (SD 4\u00b77), 795 (75%) of 1065 participants were women, and 270 (25%) were men. Self-reported race and ethnicity were: 624 (59%) Mestizo, 288 (27%) White, 72 (7%) Mulatto, 25 (2%) Mixed or other, 18 (2%) Black, 14 (1%) Indigenous, and 24 (2%) did not report race or ethnicity. 877 (82\u00b73%) of 1065 completed the 2-year follow-up. Recruitment effectiveness (Reach) was 62\u00b70%; mean adherence to the SLI group (Implementation) was 71\u00b76% over the entire trial; and frequencies of complete cognitive outcomes data (Maintenance) were 87\u00b79% at 6 months, 85\u00b73% at 12 months, 81\u00b74% at 18 months, and 84\u00b78% at 24 months in the SLI group compared with 86\u00b73% at 6 months, 78\u00b79% at 12 months, 73\u00b74% at 18 months, and 79\u00b78% at 24 months in the FLI group. Dropouts were higher in the FLI group than in the SLI group (20\u00b72% vs 15\u00b72%; p=0\u00b7042). Global cognitive composite scores increased over time in both groups, with a mean annual change of 0\u00b731 SD (95% CI 0\u00b728-0\u00b734) per year in the SLI group and 0\u00b720 SD (0\u00b717-0\u00b723) per year in the FLI group (mean between-group difference of 0\u00b711 SD per year [0\u00b706-0\u00b715; p<0\u00b70001]). Overall, 478 adverse events were reported (412 in the SLI group and 66 in the FLI group). The most common adverse events were musculoskeletal symptoms (113 [21%] in the SLI group, 13 [2%] in the FLI group), upper respiratory infections (50 [9%] in the SLI group, one [<1%] in the FLI group), and COVID-19 infection (31 [6%] events in the SLI group). Serious adverse events occurred in 50 (9%) participants in the SLI group and 24 (5%) participants in the FLI group; none were related to the intervention. There were eight deaths (three in the SLI group and five in the FLI group), and none were related to the intervention. A culturally adapted multidomain lifestyle intervention was feasible across Latin America and resulted in greater cognitive improvements than a flexible health-advice intervention in older adults at risk of cognitive decline. These findings extend the evidence base for multidomain lifestyle interventions to populations historically under-represented in dementia research, supporting their feasibility and scalability as strategies to reduce cognitive decline risk amid the rapidly growing burden of dementia in low-income and middle-income countries.

However, there is limited understanding of how HERV-K is trafficked in peripheral biofluids, and the role of exosomes, nano-sized extracellular vesicles, in this process remains largely unexplored. Exosomes offer a stable and cell-specific cargo reservoir that may reflect central pathogenic processes and serve as a minimally invasive biomarker source. In this study, we isolated plasma-derived exosomes from ALS patients (n\u2009=\u200921) and healthy controls (n\u2009=\u200916), and quantified exosomal HERV-K gag, env, and pol transcript levels using SYBR Green qPCR with RNase treatment and normalization to both traditional and exosome-enriched reference genes. HERV-K pol expression was significantly elevated in ALS, with fold-changes ranging from 1.59 to 1.85 (P\u2009=\u20090.037-0.051). env and gag also showed increased expression, though with greater variability. Normalization to the exosome-specific gene SOD2 provided the most consistent signal. These findings suggest that exosomal HERV-K transcripts, particularly pol, could serve as accessible biomarkers for patient stratification and treatment monitoring in HERV-K-targeted ALS trials. This work establishes proof-of-concept for using exosomal cargo to track endogenous retroviral activity in neurodegeneration and supports further investigation of liquid biopsy approaches in ALS precision medicine.\n\nID: 42432891\nTitle: Risk factors for distal symmetric polyneuropathy in patients with type 2 diabetes mellitus: A retrospective study.\nAbstract: The pathophysiology of distal symmetric polyneuropathy (DSPN) is multifactorial, involving chronic hyperglycemia, oxidative stress, accumulation of advanced glycation end products, impaired microvascular perfusion, metabolic toxicity, and nutritional deficiencies. Although previous studies have identified various risk factors, substantial heterogeneity exists across regions and populations, and most investigations have not comprehensively integrated metabolic markers, microvascular damage, and electrophysiological data. Therefore, a multidimensional assessment of DSPN risk factors is essential to improve early screening and risk-prediction strategies. A total of 120 patients with type 2 diabetes mellitus (T2DM) were enrolled, including 60 with DSPN and 60 without. Compared with the non-DSPN group, patients with DSPN were older, had longer diabetes duration, and demonstrated a higher prevalence of smoking, diabetic retinopathy (DR), and diabetic kidney disease. DSPN patients exhibited poorer glycemic control (higher fasting blood glucose, 2-hour postprandial blood glucose, and hemoglobin A1c [HbA1c]), more pronounced dyslipidemia (elevated triglycerides, reduced high-density lipoprotein cholesterol), and abnormalities in inflammatory and nutritional markers (elevated C-reactive protein and homocysteine [HCY], reduced vitamin B12). Renal function parameters (serum creatinine, estimated glomerular filtration rate, urine albumin-creatinine ratio) indicated more severe microvascular impairment in the DSPN group. Electrophysiological testing showed reduced sensory and motor nerve conduction velocities, decreased amplitudes, and prolonged latencies. Multivariable logistic regression identified diabetes duration, DR, elevated HbA1c, elevated HCY, and reduced sural nerve amplitude as independent risk factors for DSPN. Longer diabetes duration, DR, elevated HbA1c, elevated HCY levels, and reduced sural nerve amplitude were independently associated with DSPN in patients with T2DM. These findings may contribute to improved risk stratification and support further investigation of multidimensional approaches for early DSPN identification. This single-center retrospective cohort study included patients with T2DM treated at our hospital between June 2023 and June 2025. DSPN was diagnosed based on American Diabetes Association, European Federation of Neurological Societies, and diabetic neuropathy working group criteria using a combination of clinical symptoms, neurological signs, and nerve conduction studies. Demographic characteristics, lifestyle factors, diabetes-related complications, glucose and lipid metabolism indicators, renal function, inflammatory and nutritional markers, and electrophysiological parameters were collected. Group differences were assessed using the t-test, Mann-Whitney U test, or \u03c72 test. Variables with P\u2005<\u2005.10 in univariate analyses were entered into multivariable logistic regression to identify independent risk factors for DSPN. Sensitivity analyses and collinearity diagnostics were performed to assess the robustness of the findings.\n\nID: 42430965\nTitle: Can we identify people with Alzheimer's disease from examination of the eye? A bidirectional Mendelian randomization (MR) study.\nAbstract: Neurodegeneration in Alzheimer's disease (AD) is thought to be driven by amyloid-beta and tau deposition in the cerebral vasculature and brain. As the eye is an extension of the central nervous system, this study aimed to determine which neurovascular and neuroretinal changes in the eye are caused by AD rather than associations of the disease. Bidirectional two-sample univariable and multivariable Mendelian randomization (MR) methods were applied. Instrumental variables were derived from genome-wide association studies (GWAS) of AD and the following ocular features: thickness measurements of central macula (MT), retinal nerve fibre layer (mRNFL), ganglion cell-inner plexiform layer (mGCIPL), outer nuclear layer (ONL), inner segment layer (IS), and outer segment (OS) from macular region OCT scans; arteriolar tortuosity (AT), venular tortuosity (VT), venular width (VW), fractal dimension (FD), vertical cup-to-disc ratio (VCDR), optic cup area (OCA), and optic disc area (ODA) derived from other imaging methods. There was strong evidence that genetic liability to AD affected the retinal vasculature by specifically increasing AT (\u03b2 = 0.007;95%CI=0.002,0.011;p-value=0.005) in UK Biobank participants (n=52,798). AD may influence the mRNFL (\u03b2=-0.047,95%CI=-0.119,0.023,p-value=0.18) and mGCIPL (\u03b2=-0.061;95%CI=-0.14,0.025,p-value=0.16) of the inner retina and OS layer (\u03b2 = 0.044;95%CI=-0.0001,0.08;p-value=0.05) but the evidence was weak. Multivariable MR analysis showed that a causal relationship between optic disc area and AD (OR=0.76;95%CI=0.62,0.93,p-value=0.009) was probably mediated by refractive error. Early cerebrovascular signs of AD may be detected by examination of the eye. Further investigation is required to determine the clinical utility of eye screening for dementia.\n\nID: 42414714\nTitle: 3D OCT-Based Retinal Biomarker Analysis for Automatic Regional-Wise Characterization of Neurodegenerative Diseases.\nAbstract: Neurodegenerative diseases (NDDs) such as Alzheimer's disease (AD), essential tremor (ET), multiple sclerosis (MS), and Parkinson's disease (PD) are complex disorders that often exhibit overlapping symptoms, leading to diagnostic challenges. Given the increasing interest in retinal imaging as a non-invasive biomarker for neurodegeneration, this study proposes a fully automated machine learning pipeline for disease characterization using optical coherence tomography (OCT). We analyze macular thickness patterns across three key and relevant retinal elements: retinal nerve fibre layer (RNFL), ganglion cell layer to Bruch's membrane (GCL-BM), and the total retina. These are processed by two complementary regional layouts: the standard ETDRS scheme and a custom 3 \u00d7 3 quadrant grid. These measurements are used to train multiple classifiers to distinguish between healthy controls and NDDs either collectively or individually. The proposed method processes 34,375 OCT B-scans from 353 subjects and highlights disease-specific thickness patterns with a pathological distinction score ranging up to 0.71 depending on the retinal region, disease, and classifier. Sector-based grids generally outperform quadrant-based ones, revealing highly localized pathological signatures. Our findings demonstrate that each disease manifests distinct retinal alterations, aligning with current clinical literature while offering novel insights for ET and PD. The study reinforces the potential of grid-based OCT analysis as a discriminative and fully automatic screening tool, paving the way for improved early diagnosis and differential analysis of NDDs through retinal biomarkers.\n\nID: 42411943\nTitle: Intraoperative Lipoproteins Associated with Postoperative Delirium in a Prospective Observational Study of Older Adults Undergoing Cardiac Surgery.\nAbstract: To evaluate serum lipoproteins and other metabolites and their potential associations with the development of postoperative delirium. Prospective observational cohort study. Single-site academic medical hospital. Patients age 60 years and older scheduled for major cardiac surgery with cardiopulmonary bypass (CPB). Delirium assessments were performed at baseline and twice daily up to postoperative day 3. The primary outcome evaluated serum collected before surgery, at the start and end of CPB, and on postoperative day 1. Sixty-five patients were recruited, with 18% of subjects developing postoperative delirium within 3 days of surgery (10 of 57 subjects with complete cognitive assessments). Metabolomic analysis of serum revealed an association between the abundance of cholesterol in large high-density lipoprotein (L-HDL-C%) at the start of CPB and the development of postoperative delirium (odds ratio per standard deviation increment in biomarker concentration, 0.23; 95% confidence interval [CI], 0.08-0.66). Serum neurofilament light chain was inversely correlated with L-HDL-C% levels at the same time point (Spearman \u03c1, -0.39; 95% CI, -0.59 to -0.15) and was significantly higher at the end of CPB in subjects who developed delirium compared to subjects who did not develop delirium (median, 20.4 [interquartile range (IQR),16.1-25.4] pg/mL vs 11.9 [IQR, 7.9-16.9] pg/mL). Circulating blood biomarkers during surgery may provide insight into postoperative cognitive outcomes and should be evaluated in larger cohorts.\n\nID: 42404883\nTitle: PANoptosis in diabetic retinopathy: immunological insights into mechanisms and translational therapies.\nAbstract: Diabetic retinopathy (DR), a leading cause of blindness, is driven by hyperglycemia-induced neurovascular damage. Emerging evidence indicates that PANoptosis, an integrated inflammatory programmed cell death modality encompassing apoptosis, pyroptosis, and necroptosis, participates in the progression of diabetic retinal damage; however, the supporting evidence varies substantially across clinical specimens, diabetic animal models, high-glucose cultured retinal cells, and non-DR inflammatory disease models. This review systematically summarizes the latest advances in PANoptosis-associated mechanisms underlying DR pathogenesis, focusing on PANoptosome signaling networks, non-coding RNA-mediated regulation, and immune-metabolic crosstalk. We outline promising candidate biomarkers including PANoptosis-related gene signatures and inflammatory cell death molecules, and critically evaluate multiple translational therapeutic strategies covering small-molecule inhibitors, gene intervention, and nanomedicine delivery. Importantly, we further address context-dependent dual roles of PANoptosis, potential safety risks of non-selective PANoptosis blockade, challenges in blood-retinal barrier penetration, systemic immune side effects, and pathological heterogeneity among DR subtypes and disease stages. Since PANoptosis also fundamentally contributes to host defense and retinal innate immune homeostasis, DR therapeutic strategies should prioritize biomarker-guided, local ocular delivery, time-dependent stage intervention, and cell-type-specific fine tuning, rather than generalized systemic suppression. By reconciling mechanistic progress with unresolved translational bottlenecks, this review proposes that PANoptosis serves as a dynamic and evolving conceptual framework for interpreting inflammatory neurovascular degeneration in DR, instead of an entirely confirmed clinical therapeutic target. We emphasize the urgent need for DR-specific mechanistic verification, longitudinal biomarker cohort studies, and well-designed multicenter clinical trials to advance safe and precise targeted interventions.\n\nID: 42404345\nTitle: Development of a risk stratification tool for rapidly progressive diabetic retinopathy in type 2 diabetes.\nAbstract: The progression of rapidly progressive diabetic retinopathy (PDR) in type 2 diabetes mellitus (T2DM) is characterized by substantial inter-individual variability. To develop and validate a nomogram for individualized risk prediction and stratification of rapidly progressive PDR in T2DM by incorporating diabetes duration, glycated hemoglobin (HbA1c), 24-hour urinary protein quantification, growth differentiation factor 15 (GDF15), Diabetic Retinopathy Severity Scale (DRSS) grade, and foveal avascular zone area. This retrospective study enrolled 342 patients with T2DM (1999 WHO criteria), randomly assigned to training (n=240) and validation (n=102) sets (7:3 ratio). Baseline demographic, clinical, metabolic, renal, inflammatory biomarker, and ophthalmic imaging data were collected. Predictive variables were selected via univariate analysis and least absolute shrinkage and selection operator (LASSO) regression. Independent predictors identified by multivariable logistic regression were incorporated into a nomogram. For comparison, Random Forest, multivariable logistic regression, and Gradient Boosting Machine models were also developed. Model performance was assessed using the area under the receiver operating characteristic curve (AUC-ROC), calibration curves, and decision curve analysis (DCA). Univariate analysis identified six significant factors (all P\u00a0<\u00a00.05): diabetes duration, HbA1c, 24-hour urinary protein quantification, GDF15, DRSS grade, and foveal avascular zone area. LASSO regression retained all six, and multivariable logistic regression confirmed them as independent risk factors for rapidly progressive DR in T2DM (all P\u00a0<\u00a00.05). Three machine learning models were constructed. The Random Forest model achieved the numerically highest validation AUC (0.780) compared with Gradient Boosting Machine (0.741) and multivariable logistic regression (0.698), though the DeLong test showed no statistically significant difference between Random Forest and Gradient Boosting Machine (P\u00a0=\u00a00.38). Calibration curves showed good consistency between predicted and observed probabilities. DCA indicated high clinical net benefit of the model at 0.1-0.8 threshold probability vs other models and extreme strategies. A novel risk prediction model for rapidly progressive PDR in T2DM was developed and validated by integrating multidimensional parameters. Demonstrating favorable discrimination, calibration, and clinical utility, this model provides a promising tool for early identification of high-risk individuals and optimization of personalized intervention strategies.\n\nID: 42396530\nTitle: Sigma1 Receptor Activation Confers Durable Neuroprotection Following Neonatal Ischemic Retinal Injury.\nAbstract: Retinopathy of prematurity (ROP) remains a leading cause of childhood blindness. Although current therapies effectively suppress pathological neovascularization, many patients continue to exhibit persistent visual dysfunction despite regression of active disease, highlighting an unmet need for neuroprotective interventions. Sigma 1 receptor (Sig1R), an endoplasmic reticulum-mitochondrial chaperone and regulator of cellular stress responses, has emerged as a promising therapeutic target in neurodegenerative and retinal diseases. Here, we investigated whether Sig1R activation confers sustained neuroprotection following neonatal ischemic retinal injury. Wild-type and Sig1R knockout mice were subjected to oxygen-induced retinopathy (OIR) and treated systemically with the high-affinity Sig1R agonist (+)-pentazocine [(+)-PTZ]. Retinal structure and visual function were assessed longitudinally through 20 weeks of age using visual acuity, contrast sensitivity, electroretinography (ERG), pattern ERG (PERG), spectral-domain optical coherence tomography (SD-OCT), and histological analyses. Chronic Sig1R activation significantly preserved visual acuity, contrast sensitivity, rod- and ganglion cell-mediated retinal function, retinal ganglion cell survival, and inner retinal architecture in OIR mice. These protective effects were abolished in Sig1R-deficient mice, demonstrating a requirement for Sig1R in mediating neuroprotection. Mechanistically, Sig1R activation reduced apoptotic signaling, attenuated oxidative and nitrosative stress, improved mitochondrial respiratory function, and enhanced endogenous antioxidant pathways. Collectively, these findings demonstrate that Sig1R activation provides durable, receptor-dependent neuroprotection following neonatal ischemic retinal injury by coordinating redox, mitochondrial, and cell-survival pathways. These results identify Sig1R as a promising therapeutic target for preserving retinal neuronal integrity and long-term visual function in retinopathy of prematurity.\n\nID: 42390572\nTitle: Retinal imaging for cerebrovascular risk stratification: evidence, limitations, and practical thresholds for the ophthalmologist.\nAbstract: The retina shares developmental origin, microvascular anatomy, and barrier physiology with the brain, making non-invasive retinal imaging a candidate window onto cerebrovascular burden. Despite a growing body of association data, translational claims in this field have frequently outpaced the evidence, and clinically actionable guidance for the practising ophthalmologist remains sparse. This review asks a deliberately narrow question: which retinal imaging domains provide evidence mature enough to inform clinical decisions about cerebrovascular risk, and which remain investigational? Narrative review of the published literature on five retinal imaging domains: (1) classical fundus signs and quantitative vessel-calibre analysis; (2) retinal vessel geometry including fractal dimension and tortuosity; (3) optical coherence tomography (OCT) structural analysis; (4) optical coherence tomography angiography (OCTA); and (5) artificial intelligence (AI) and oculomics. Evidence was appraised with emphasis on study design, population size, confounding control, external validity, and translational distance from clinical practice. The literature search was updated to March 2026. Classical retinal microvascular abnormalities and quantitative vessel-calibre metrics carry the strongest and most reproducible evidence base, particularly for cumulative vascular burden, lacunar stroke phenotypes, and cerebral small-vessel disease (cSVD). Retinal vessel fractal dimension adds incremental signal for the cSVD phenotype, with recent Mendelian randomisation data suggesting causal rather than purely associative relationships between retinal vascular morphology and stroke. OCT structural analysis shows consistent associations with ischaemic stroke and cSVD-related neurodegeneration, but the absence of validated clinical thresholds limits immediate applicability. OCTA deepens neurovascular phenotyping but is constrained by device heterogeneity, segmentation variability, and ocular confounding. AI-based oculomics, including foundation-model approaches, demonstrates credible discrimination for silent brain infarction and stroke-risk enrichment, though no randomised controlled trial has yet demonstrated that retinal AI improves cerebrovascular outcomes, and current translational limits remain substantial. Retinal imaging is best positioned as a neurovascular phenotyping tool rather than a stand-alone stroke prediction instrument. The ophthalmologist's highest-value contribution is recognising when embolic, asymmetric, clustered, or disproportionate retinal findings should lower the threshold for broader vascular assessment or neurological referral. Integration with Doppler ultrasound vascular assessment - including ophthalmic artery flow evaluation, carotid haemodynamics, and orbital haemodynamic asymmetry - substantially extends the clinical reach of retinal phenotyping and is highlighted as a mechanistically complementary dimension of extracranial cerebrovascular evaluation. This review provides a practical, pattern-based framework applicable in routine ophthalmic care.\n\nID: 42388876\nTitle: A machine learning model for diabetic retinopathy risk stratification using routine blood and urine parameters: insights into kidney-eye crosstalk.\nAbstract: This study aimed to develop and externally validate an interpretable machine learning (ML) model for diabetic retinopathy (DR) risk stratification using routine clinical biomarkers, and to explore potential probabilistic dependencies and interactive pathways between clinical biomarkers and DR pathogenesis through Bayesian network modeling. We integrated clinical data from the National Health and Nutrition Examination Survey (NHANES) with an independent hospital cohort (Nantong First People's Hospital). A multi-stage feature selection pipeline (Boruta algorithm and LASSO regression) was utilized to identify core predictors. Eight ML algorithms were benchmarked. To transcend conventional \"black-box\" predictions, we coupled SHAP (SHapley Additive exPlanations) for personalized interpretability with a Bayesian Network Directed Acyclic Graph (DAG) to map the probabilistic dependency structure among the selected systemic biomarkers. The LightGBM algorithm outperformed other classifiers, yielding a robust external validation AUC of 0.841 (95% CI: 0.809-0.862). Fourteen key routine predictors were identified, spanning glycemic control, renal function, and lipid metabolism. Crucially, probabilistic dependency structure via the Bayesian Network revealed a hierarchical pathogenetic topology: rather than parallel associations, latent renal impairment markers (urine protein, BUN, and urine creatinine) and chronic glycemic toxicity (HbA1c) emerged as direct upstream dependency drivers of DR. This structural evidence suggests a probabilistic dependency consistent with the 'kidney-eye crosstalk' hypothesis. We successfully deployed a high-performing, non-invasive LightGBM model for early DR screening. By integrating predictive ML with probabilistic dependency structure, this framework not only delivers an accessible, web-based clinical decision support system (CDSS) for resource-constrained settings but also provides preliminary insights into the potential systemic microvascular interplay driving diabetic retinopathy.\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: 42367645\nTitle: Occurrence of amyotrophic lateral sclerosis during TNF inhibitor treatment in inflammatory rheumatic disease. What are the relationships?\nAbstract: Neurological adverse events have been reported in patients receiving tumor necrosis factor inhibitors (TNFi) for the treatment of inflammatory rheumatic diseases. The occurrence of amyotrophic lateral sclerosis (ALS) during TNFi therapy is rare but raises the question of a possible relationship. We report 2 cases of ALS diagnosed during TNFi treatment: the first in a patient with spondyloarthritis treated with adalimumab and the second in a patient with seronegative polyarthritis treated with infliximab. Tumor necrosis factor alpha (TNF\u03b1) has been implicated in ALS pathogenesis and is considered to exert both neuroprotective and neurotoxic effects, depending on the differential expression of its receptors in distinct regions of the central nervous system. We also review data from pharmacovigilance databases and discuss the potential influence of TNF\u03b1 inhibition on ALS development.\n\nID: 42360388\nTitle: Deletion of CEACAM1 does not affect retinal and choroidal morphology or transcriptome.\nAbstract: CEACAM1 (CC1) is an important mediator of cell proliferation and adhesion and serves as an angiogenic factor through interaction with VEGF. Although the role of CC1 has been extensively studied in organs such as the heart, liver and lung in which CC1 is considered an important regulator of various pathological conditions, little is known about the function of CEACAM1 in the eye. In this study, we investigated the expression and function of CC1 in the retina and choroid of healthy adult mice using immunohistochemistry, fluorescence activated cell sorting (FACS) and RNA sequencing. We found CC1 to be expressed in endothelial and myeloid cells of the retina and the choroid. However, deletion of CC1 did not result in vascular abnormalities of the retina and choroid or changes in retinal myeloid cell morphology and number. Furthermore, the retinal architecture was not affected and morphometric measurements of the thickness of the inner and outer retinal layers were not altered by deletion of CC1. Accordingly, we did not observe structural or transcriptomic changes in the choroid. Our data suggest that the role of CC1 in the adult eye during steady state is attenuated or can be compensated by other molecular mediators. However, one could speculate that CC1 may become functionally relevant during pathological conditions, such as in neovascular eye diseases like proliferative diabetic retinopathy or neovascular age-related macular degeneration.\n\nID: 42360043\nTitle: Comparison of Proteomic Analysis of Cerebrospinal Fluid From Neurological Patients With and Without Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterised by progressive muscle weakness in both bulbar and extremity muscles, leading to a diverse clinical phenotype with motor and non-motor symptoms. Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease.\n\nID: 42358678\nTitle: Early proteomic and metabolomic signatures in diabetes associated with progression to diabetic retinopathy over 1-2 years.\nAbstract: The progression from diabetes mellitus (DM) to diabetic retinopathy (DR) represents a dynamic pathological process in which vascular and metabolic alterations gradually lead to retinal damage. Understanding the molecular changes during this transition is critical for timely identification and intervention. We performed DIA-based proteomics and untargeted metabolomics on longitudinal paired plasma samples from 15 DM patients who developed DR during 1-2 years. Differential expression, pathway enrichment, and protein-metabolite correlation analyses were performed. Key proteins were validated by ELISA in an independent cohort of 22 DM patients without DR and 22 NPDR patients, and their predictive performance for DR progression was assessed using receiver operating characteristic (ROC) curve analysis. Proteomic analysis identified 57 differentially expressed proteins enriched in energy metabolism, detoxification, and cellular defense responses. Metabolomic profiling revealed 168 differential metabolites, primarily involved in taurine and hypotaurine metabolism, neuroactive ligand-receptor interaction, and tyrosine metabolism. Integrated proteomic-metabolomic analysis revealed significant correlations between proteins and metabolites. Eight candidate proteins were validated by ELISA, including three previously reported in DR (Annexin A1 (ANXA1), Glutathione Peroxidase 1 (GPX1), Glutathione S-transferase Mu 1 (GSTM1)) and five newly identified candidates (Aldehyde Dehydrogenase 18 family member A1 (ALDH18A1), Galactose-1-Phosphate Uridylyltransferase (GALT), Proteoglycan 2 (PRG2), Ubiquitin-activating Enzyme E1 (UBA1), Glucagon (GCG)). ROC analysis demonstrated strong discriminative performance for these proteins, with area under the curve (AUC) values ranging from 0.853 to 0.945. Our study reveals coordinated alterations in plasma proteins and metabolites during the progression from DM to DR. Integrated multi-omics analysis identified five novel candidate biomarkers, which may serve as potential targets for early detection and risk stratification of DR.\n\nID: 42356170\nTitle: Cup-to-Disc Ratio Is Associated with Disability in Multiple Sclerosis: A Combined OCT and Subjective Visual Vertical Study.\nAbstract: Background and Objectives: Non-invasive biomarkers reflecting neurodegeneration are increasingly important in multiple sclerosis (MS). Optical coherence tomography (OCT) provides quantitative measures of retinal structure, most commonly peripapillary retinal nerve fiber layer (pRNFL) thickness. However, the potential clinical relevance of optic nerve head morphology, including cup-to-disc ratio (CDR), remains insufficiently explored. We investigated associations between OCT-derived parameters, subjective visual vertical (SVV), and disability in MS. Materials and Methods: In this retrospective study, 100 patients with MS were included. OCT parameters (pRNFL thickness and area-based CDR) were analyzed at baseline and follow-up. Clinical disability was assessed using the Expanded Disability Status Scale (EDSS). Detailed optic neuritis history was not consistently available in the retrospective clinical records and therefore could not be systematically accounted for in the analyses. SVV was evaluated in 37 patients using a virtual reality-based protocol. Associations were assessed using Spearman correlation and linear regression analyses. Multivariable regression models were adjusted for age, sex, and follow-up duration. Results: pRNFL thickness was not associated with baseline EDSS (rho = -0.06, p = 0.55) or annualized EDSS change. Baseline CDR correlated with both baseline EDSS (rho = 0.30, p = 0.0065) and follow-up EDSS (rho = 0.46, p < 0.0001). In univariable regression analysis, baseline CDR was associated with follow-up EDSS (B = 3.33, R2 = 0.23, p < 0.0001), remaining significant after adjustment for age, sex, and follow-up duration (B = 2.59, 95% CI 1.26-3.92, p = 0.0002). No significant associations were observed between OCT parameters and SVV measures. Conclusions: Higher CDR values, but not pRNFL thickness, were associated with disability measures in this exploratory MS cohort. However, these findings should be interpreted cautiously because optic neuritis history could not be systematically accounted for and physiological optic disc variability may substantially influence CDR measurements.\n\nID: 42356165\nTitle: Foveal Density and Multi-Domain OCTA Biomarkers May Help Identify Preclinical Diabetic Microvasculopathy in Type 2 Diabetes Mellitus.\nAbstract: Background and Objectives: Type 2 diabetes mellitus (T2DM) causes retinal microvascular changes that precede clinically apparent diabetic retinopathy (DR). We aimed to identify which optical coherence tomography angiography (OCTA) biomarkers best distinguish eyes with T2DM without clinical DR from healthy controls and to evaluate machine learning classifiers trained on a comprehensive 68-parameter OCTA panel. Materials and Methods: In this prospective case-control study, 80 patients with T2DM without clinical DR and 33 controls underwent 3 \u00d7 3 mm macular OCTA using an Optovue RTVue Avanti System. After outlier screening, 221 eyes (155 T2DM, 66 controls) were analyzed. Sixty-eight OCTA parameters were extracted, covering FAZ morphometry (including foveal density FD-300), SCP and DCP vessel density and layer thickness, outer-retina and choriocapillaris flow, and a full retinal-thickness map. Between-group comparisons used the Mann-Whitney U test with Benjamini-Hochberg FDR correction. Logistic regression, random forest, and XGBoost classifiers were evaluated with patient-grouped 10-fold cross-validation; feature importance was quantified via SHAP. Results: Forty-two of 68 parameters reached FDR significance (q < 0.05). Deep capillary plexus vessel density was the most discriminative family (whole image rb = -0.66, q = 2.5 \u00d7 10-13; parafovea rb = -0.64). FD-300 was reduced in T2DM (median 47.55% vs. 51.86%; rb = -0.57; q = 1.0 \u00d7 10-10) and emerged as the top SHAP feature (mean |SHAP| = 0.81). FAZ circularity decreased without FAZ-area enlargement, and outer-retina flow was paradoxically elevated (rb = +0.39), consistent with a projection artifact. XGBoost using all 68 features achieved a patient-grouped cross-validated AUC of approximately 0.91, compared with 0.85 for conventional SCP + DCP whole-image density. No parameter correlated with current HbA1c in T2DM (all q > 0.98), and the well-controlled (<7%) and poorly controlled (\u22657%) subgroups were indistinguishable across five of six principal biomarkers, consistent with metabolic memory. FD-300 remained independent after adjustment for hypertension, hyperlipidemia, and age (OR = 0.76; 95% CI 0.69-0.84; p < 0.001). Conclusions: A multi-compartment OCTA panel outperforms conventional two-layer vessel-density metrics in detecting preclinical diabetic microvasculopathy, although external validation is required before clinical use. FD-300 is the single most informative biomarker, while choriocapillaris and retinal thickness measures provide complementary, compartment-specific signals. Because the OCTA signature is decoupled from the current HbA1c, screening should not be deferred in well-controlled T2DM.\n\nID: 42353250\nTitle: Microglial Dysfunction Induced by C9ORF72 Dipeptide Repeat Proteins: Biomarker and Therapeutic Perspectives.\nAbstract: The GGGGCC hexanucleotide repeat expansion (HRE) in C9ORF72 was recognized as the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Repeat-associated non-AUG (RAN) translation of the expanded repeat generated dipeptide repeat proteins (DPRs), which disrupted multiple cellular processes and contributed to neurodegeneration. Emerging evidence indicated that disease pathogenesis involved both gain-of-function (GOF) and loss-of-function (LOF) mechanisms. DPR-mediated GOF toxicity induced ribosomal dysfunction, nucleolar stress, proteostatic impairment, and neuronal injury, whereas C9ORF72 LOF disrupted lysosomal and autophagic pathways in microglia, impairing the immune homeostasis. Neuronal injury further promoted the release of damage-associated signals that triggered secondary microglial activations and chronic neuroinflammations. This review summarized current knowledge of DPR biology, microglial dysfunction, and their contributions to disease progression in C9ORF72-associated ALS/FTD. Therapeutic strategies targeting repeated RNA, DPR productions, proteostasis, autophagy, and neuroinflammatory pathways were also discussed. In addition, the potentials of fluid biomarkers, including cerebrospinal fluid poly (GP) and blood neurofilament light chain (NfL), for diagnosis, disease monitoring, and therapeutic assessment were shown. Together, these findings provided important insights into disease mechanisms and potential avenues for improved clinical management.\n\nID: 42352375\nTitle: Extracellular Vesicles and Diabetes Research: Current Status and Future Promise.\nAbstract: Diabetes mellitus represents a major global health challenge with rapidly increasing prevalence and substantial morbidity driven by metabolic and vascular complications. Extracellular vesicles (EVs) have emerged as critical mediators of intercellular communication and are increasingly implicated in the pathogenesis and progression of diabetes. This review summarizes current knowledge on EV biology, including their classification, cellular sources, biogenesis, uptake mechanisms, and molecular cargo. We discuss the contribution of EV-associated microRNAs to immune dysregulation and \u03b2-cell damage in type 1 diabetes mellitus (T1DM), as well as the role of EVs in insulin resistance, metabolic signaling, and vascular dysfunction in type 2 diabetes mellitus (T2DM). Particular emphasis is placed on EV-mediated modulation of endothelial function, angiogenesis, and tissue repair, alongside their involvement in the impairment of insulin receptor integrity. We further explore how lifestyle factors may influence EV composition and function, highlighting their potential integration into preventive strategies. Finally, we evaluate the emerging therapeutic potential of EVs as biomarkers and delivery systems, while addressing current limitations and future directions. Collectively, EVs represent a promising frontier in understanding diabetes pathophysiology and developing innovative diagnostic and therapeutic approaches. Unlike previous reviews that examine EVs separately as biomarkers or therapeutic vehicles, this review integrates emerging evidence supporting EVs as mediators of systemic communication linking pancreatic islets, adipose tissue, immune cells, vascular endothelium, kidney, heart, and retina throughout diabetes progression. We further critically evaluate translational barriers that currently limit clinical implementation of EV-based diagnostics and therapeutics.\n\nID: 42348200\nTitle: Neuroretinal Layer Thinning on OCT Imaging and Hemoglobin A1c in Youth With Type 1 Diabetes.\nAbstract: Diabetic retinal neurodegeneration precedes vascular changes associated with diabetic retinal disease (DRD). Studies in adults with type 1 diabetes (T1D) show there is retinal layer thinning with DRD, yet there are limited data in youth with T1D. To determine if retinal layer thickness changes on optical coherence tomography (OCT) imaging were associated with glycemic outcomes and DRD in youth. This prospective cohort study was conducted at an academic pediatric diabetes center among youth with T1D aged 9 to 21 years participating in the ACCESS2 (AI for Pediatric Diabetic Eye Exams Study 2) study. Participants were enrolled and data were collected July 11, 2022, and April 30, 2025. Data analysis was performed from June 2025 through October 2025. OCT imaging. The primary outcome was macular OCT volumes, which were segmented by the Topcon Maestro camera software and reviewed by the Wisconsin Reading Center for 3 neuroretinal layers: (1) retinal nerve fiber layer (RNFL) thickness, (2) ganglion cell and inner plexiform layer (GCL+IPL) thickness, and (3) GCL+IPL+RNFL thickness, as well as total retinal thickness. Layer thicknesses were analyzed for associations with glycemic outcomes and DRD and for potential covariates. A total of 294 youth with T1D (n\u2009=\u2009578 eyes), among whom mean (SD) age was 15.8 (2.8) years, 153 participants (52.0%) were female, and 108 participants (36.7%) had public insurance, were included. Participants had a median (IQR) duration of diabetes of 7.0 (4.6-10.1) years and a median (IQR) hemoglobin A1c (HbA1c) of 8.5% (7.5%-9.9%); 210 participants (71.4%) used an insulin pump. Of the total 578 eyes, 65 eyes (11.2%) had mild DRD and 10 eyes (1.73%) had moderate DRD. In adjusted analyses, moderate DRD vs no DRD was associated with RNFL thickness of -1.2 \u00b5m (95% CI, -2.9 to 0.5; P\u2009=\u2009.20), GCL+IPL thickness of -1.2 \u00b5m (95% CI, -2.8 to 0.4; P\u2009=\u2009.19), and outer retinal layer thickness of -0.8 \u00b5m (95% CI, -3.9 to 2.2; P\u2009=\u2009.80). In multivariable models, GCL+IPL and outer retinal layer thickness were associated with HbA1c (\u03b2\u2009=\u2009-0.39; 95% CI, -0.78 to -0.01; P\u2009=\u2009.04; and \u03b2\u2009=\u2009-0.81; 95% CI, -1.49 to -0.12; P\u2009=\u2009.02, respectively). In this prospective cohort study, neuroretinal layer thinning was observed in youth with T1D without clinically apparent DRD and was associated with higher HbA1c. These findings support elucidating the development of diabetic retinal neurodegeneration and its potential role as a biomarker of retinal vascular disease in youth.\n\nID: 42347979\nTitle: Levels of DEL-1 and IL-17 in the aqueous humor of cataract patients with diabetes without diabetic retinopathy.\nAbstract: This study aimed to investigate whether DEL-1 and IL-17 levels in the aqueous humor are elevated in patients with diabetic cataract and to evaluate the potential of these biomarkers for early diagnosis or for monitoring of ocular inflammation. IL-17 is a proinflammatory cytokine implicated in diabetes-related microvascular and ocular inflammatory processes, particularly in diabetic retinopathy, whereas DEL-1 is an endogenous anti-inflammatory molecule that counter-regulates IL-17-mediated immune responses and contributes to vascular and immune homeostasis. Aqueous humor samples were collected during cataract surgery from type 2 diabetic cataract patients without diabetic retinopathy (n\u2009=\u200933) and from non-diabetic cataract patients serving as controls (n\u2009=\u200928). DEL-1 and IL-17 concentrations were measured using enzyme-linked immunosorbent assay (ELISA). Correlation analyses were performed to explore the associations between biomarker levels and clinical parameters, including age, duration of diabetes, fasting blood glucose, HbA1c, and macular thickness. Mean aqueous humor DEL-1 levels were 0.27\u2009\u00b1\u20090.21\u00a0pg/mL in diabetic cataract patients without retinopathy and 0.36\u2009\u00b1\u20090.30\u00a0pg/mL in non-diabetic controls. Mean IL-17 levels were 59.82\u2009\u00b1\u200922.16\u00a0pg/mL and 59.78\u2009\u00b1\u200920.73\u00a0pg/mL, respectively. No statistically significant differences were observed between the groups for either biomarker (p\u2009=\u20090.305 for DEL-1; p\u2009=\u20090.839 for IL-17). Aqueous humor DEL-1 and IL-17 levels were not significantly elevated in diabetic cataract patients without diabetic retinopathy, and their potential diagnostic value for detecting subclinical ocular inflammation during the pre-diabetic retinopathy stage remains to be clarified. The findings indicate that local immune responses, rather than systemic diabetes alone, may play a more critical role. Further research is warranted to clarify their clinical applicability.\n\nID: 42344673\nTitle: Magnetoencephalography biomarkers for assessing myelin content and neuronal function in acute optic neuritis.\nAbstract: The visual pathway is an important model system for remyelination and neuroprotection trials in multiple sclerosis, due to its accessibility and the availability of validated methods including visual evoked potential and optical coherence tomography. However, visual evoked potentials are sometimes undetectable and demonstrate limited reliability after acute optic neuritis. This study aims to investigate novel magnetoencephalography markers for assessing myelin content and neuronal dysfunction in the early phase of optic neuritis and describes their inter-run reproducibility ('over a single visit') and association with short-term visual outcomes. Patients with unilateral acute optic neuritis were recruited and underwent ophthalmological assessments, brain MRI and magnetoencephalography. Magnetoencephalography data were acquired during visual stimulation with an alternating checkerboard pattern. We used source localization to reconstruct brain activity in the primary visual cortex (V1) and analysed it in the temporal and frequency domains. In the temporal domain, we focused on M100 latency-the magnetic counterpart of P100 latency. In the frequency domain, we assessed the spectral richness of the steady-state evoked field response by harmonic count, which reflects the diversity of frequency components present in the brain signal. Thirty-two patients were included at a median of 54 days [interquartile range = (37.5-78)] post-symptom onset of optic neuritis. Among patients with optic neuritis, visual evoked field recordings were detectable in 77% of cases, compared with 66% for visual evoked potential recordings. M100 latency demonstrated an excellent inter-run reproducibility for both fellow and affected eyes [intra-class correlation coefficient (ICC) >0.8, mean absolute inter-run difference of 2.99 \u00b1 6.53 and 3.76 \u00b1 7.53\u2005ms, respectively]. By comparison, the reproducibility of P100 latency was good for fellow eye (ICC = 0.7, mean absolute inter-run difference of 3.9 \u00b1 6.2\u2005ms) but moderate for affected eye (ICC = 0.6, mean absolute inter-run difference of 9.1 \u00b1 21.8\u2005ms). In the frequency domain, the harmonic count correlated strongly with ganglion cell layer volume (r = 0.68, P = 0.0001), likely reflecting functional consequences of neuronal loss. Measures reflecting demyelination (P100 and M100 latencies) correlated with measures of neuronal damage (ganglion cell layer volume and harmonic count) from both conventional and magnetoencephalography assessments. Visual impairment was associated with neuronal damage (parameter estimates: \u03b2 = 0.49, P = 0.017 for ganglion cell layer volume, \u03b2 = 0.57, P = 0.003 for harmonic count) but not with demyelination measures. Our results highlight magnetoencephalography as a reproducible and comprehensive tool to study both myelin content and neuronal dysfunction shortly after optic neuritis and suggest that, at this early stage, neuronal damage is already the main driver of visual outcome.\n\nID: 42149122\nTitle: cGAS-STING Pathway Mediates Retinal Pigmental Epithelial Dysfunction in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) is a predominant cause of vision impairment among working-age individuals, with a subset of patients responding poorly to current treatments. This study investigated alterations in double-stranded DNA (dsDNA) levels in the aqueous humor and retinal pigment epithelium (RPE) dysfunction in DR patients, exploring the potential role of the cyclic GMP-AMP synthase (cGAS)-STING pathway in DR progression. We found that DR patients showed significantly elevated dsDNA levels in the aqueous humor compared with control individuals. Fundus autofluorescence imaging revealed an increase in high-autofluorescence spots in DR patients, indicating early RPE dysfunction. In vivo and in\u00a0vitro models of DR demonstrated mitochondrial damage and dsDNA leakage in RPE cells, along with cGAS-STING pathway activation in the retina. Pharmacological inhibition of STING reduced cytoplasmic dsDNA accumulation and damaged mitochondria, alleviating inflammation in\u00a0vitro. In vivo, STING inhibition ameliorated RPE dysfunction and vascular changes. These findings highlight the critical role of the cGAS-STING pathway in DR pathogenesis and suggest that STING inhibition may serve as a promising therapeutic strategy to reduce retinal inflammation and slow the progression of DR. The retinal pigment epithelium (RPE) serves as the outer blood-retinal barrier, protecting the neural retina from systemic changes. We aimed to preserve RPE integrity through early intervention and inhibit DR progression. Our study focused on determining whether the involvement of the cyclic GMP-AMP synthase-STING pathway and mitochondrial damage drive RPE dysfunction. We found that mitochondrial dysfunction in the RPE under diabetic conditions triggers activation of the cyclic GMP-AMP synthase-STING pathway, leading to disruption of RPE and retinal vascular instability. Targeting this pathway restored RPE function and limited retinal deterioration. These findings highlight a promising therapeutic approach for preventing disease progression.\n\nID: 41631753\nTitle: Theophylline Inhibits Capillary Degeneration in Early Diabetic Retinopathy.\nAbstract: Recent evidence suggests that simultaneous inhibition of multiple diabetes-induced molecular abnormalities is a valuable approach toward inhibiting the development of early stages of diabetic retinopathy (DR). The methylxanthine, theophylline acts by multiple mechanisms in different diseases, and we investigated its effect on the development of lesions of early DR. Wild-type C57Bl/6J male mice were made diabetic with streptozotocin at two to three months of age, and some were given theophylline or structurally related analogs for one to two months to assess effects on visual function and biochemical and physiological abnormalities in the retina, or for eight months to assess retinal vascular histopathology. Effects of theophylline on leukocytes were examined ex vivo, because leukocytes contribute to the retinal vascular pathology of diabetes. Retinal superoxide generation, expression of inflammatory proteins, leukocyte-mediated cytotoxicity against retinal endothelial cells, and degeneration of retinal capillaries were significantly increased in retinas of control diabetic mice, and theophylline inhibited each of these abnormalities. Of recognized actions of theophylline (adenosine receptor antagonist, antioxidant and anti-inflammatory agent, inducer of histone deacetylase activity, inhibitor of phosphodiesterases), the inhibition of phosphodiesterases, oxidative stress and inflammation seem most likely to account for the beneficial effects of the drug in DR. In contrast to the beneficial effect of theophylline on capillary degeneration, it did not inhibit the diabetes-induced dysfunction of the neural retina. Theophylline significantly inhibited the degeneration of retinal capillaries in early DR and can help investigate mechanistic differences in the pathogenesis of retinal capillary degeneration and neural dysfunction in diabetes.\n\nID: 41513898\nTitle: Heterogeneous phenotype and cardiovascular comorbidities in Swedish patients with spinobulbar muscular atrophy.\nAbstract: Spinobulbar muscular atrophy (SBMA) is an X-linked neuromuscular disorder characterized by adult-onset progressive muscle atrophy, flaccid paresis, and bulbar palsy. In addition, increasing evidence indicates that SBMA is a multisystem disorder with prominent non-motor symptoms, such as sensory neuropathy, androgen insensitivity, and glucose intolerance. This study aimed to further characterize the clinical manifestations and biomarker profile in a large Swedish SBMA cohort. 49 genetically confirmed SBMA patients were identified from a motor neuron disease database at Ume\u00e5 University Hospital, Sweden. CAG repeat length in the androgen receptor (AR) gene was assessed by RP-PCR. Blood samples were analyzed for cardiovascular and muscle biomarkers. Clinical data were collected from medical records and interviews, with autopsy findings reviewed in two cases. The mean CAG repeat length was 43.1, with a mean age at motor symptom onset of 58.6\u00a0years. Notably, 19% of patients initially presented with sensory symptoms. High prevalence of hypertonia (70%), diabetes mellitus (39%), and cardiac disease (38%) was observed. Elevated troponin levels were common, and pNfL (neurofilament light chain in plasma) was elevated in seven patients, likely reflecting combined cerebrovascular and cardiovascular comorbidity. Importantly, two of these seven patients exhibited rapid disease progression, and a concomitant diagnosis of ALS was confirmed histopathologically. This cohort was characterized by a relatively low number of AR gene CAG repeats and a late onset of motor symptoms. Sensory symptoms frequently occurred before motor decline. Cardiovascular disease and diabetes were common comorbidities and, in some cases, preceded neurological symptoms. These findings underscore the need for improved clinical awareness of the heterogeneous presentation of SBMA and support routine cardiovascular monitoring to reduce diagnostic delays and prevent early mortality.\n\nID: 41493706\nTitle: MicroRNAs and Long Non-Coding RNAs Affect the Mechanisms Involved in Age-Related Neurodegeneration in a Manner Depending on RNA-Binding Proteins.\nAbstract: Neurodegenerative diseases (NDs), including Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and Huntington's disease (HD), are marked by progressive neuronal loss and aberrant protein aggregation, presenting substantial global healthcare challenges. Recent research has illuminated the pivotal roles of RNA-binding proteins (RBPs) and non-coding RNAs (ncRNAs), notably microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), in the molecular pathogenesis of age-related neurodegeneration. RBPs orchestrate RNA metabolism and engage extensively with miRNAs and lncRNAs to modulate gene expression at the post-transcriptional level. Dysregulation of these interactions precipitates pathological phenomena such as protein misfolding, stress granule formation, and disrupted RNA processing, thereby exacerbating neuronal dysfunction and death. Specific miRNAs have been implicated in regulating key neurodegenerative biomarkers, including tau and amyloid-\u03b2 in AD, motor neuron maintenance in ALS, and survival pathways in HD. Elucidating the intricate interplay between RBPs and ncRNAs holds significant promise for the development of therapeutic strategies aimed at ameliorating RNA-mediated mechanisms in neurodegenerative disorders.\n\nID: 41171761\nTitle: Phospho-proteome profiling in human neurons reveals targets of TBK1 in ALS/FTD-associated autophagy networks.\nAbstract: Loss-of-function variants in TBK1, encoding a protein kinase, are strongly associated with familial amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). However, how haploinsufficiency for TBK1 leads to age-related neurodegeneration remains unresolved. Here, we utilize sets of isogenic induced pluripotent stem cells (iPSCs) with loss of TBK1 or loss of optineurin (OPTN) for quantitative global proteomics and phospho-proteomics in both stem cells and excitatory neurons. We found that TBK1 sustains the abundance and phosphorylation of its interacting adapter proteins, AZI2/NAP1, TANK, and TBKBP1/SINTBAD. Moreover, TBK1 regulates the phosphorylation of endo-lysosomal proteins, such as GABARAPL2, the late-endosome GTPase RAB7A, and selective autophagy cargo receptor proteins-including novel phospho-sites in p62/SQSTM1-in neurons. Finally, we provide a census of the phospho-proteome in nascent human neurons for further studies. Overall, TBK1 serves as a point of convergence in ALS/FTD-linked endo-lysosomal networks that act in a cell-autonomous manner to maintain protein homeostasis in neurons.\n\nID: 41008559\nTitle: Mitochondrial Aging in the CNS: Unravelling Implications for Neurological Health and Disease.\nAbstract: Mitochondrial aging plays a central role in the functional decline of the central nervous system (CNS), with profound consequences for neurological health. As the brain is one of the most energy-demanding organs, neurons are particularly susceptible to mitochondrial dysfunction that arises with aging. Key features of mitochondrial aging include impaired mitochondrial dynamics, reduced mitophagy, increased production of reactive oxygen species (ROS), and accumulation of mitochondrial DNA (mtDNA) mutations. These alterations dramatically compromise neuronal bioenergetics, disrupt synaptic integrity, and promote oxidative stress and neuroinflammation, paving the path for the development of neurodegenerative diseases. This review also examines the complex mechanisms driving mitochondrial aging in the central nervous system (CNS), including the disruption of mitochondrial-organelle communication, and explores how mitochondrial dysfunction contributes to neurodegenerative diseases, such as Alzheimer's, Parkinson's, Huntington's, and amyotrophic lateral sclerosis. By synthesizing current evidence and identifying key knowledge gaps, we emphasize the urgent need for targeted strategies to restore mitochondrial function, maintain cognitive health, and delay or prevent age-related neurodegeneration.\n\nID: 40843317\nTitle: Upregulation of SQSTM1 Regulates Ferroptosis and Oxidative Stress in M\u00fcller Cells of the Diabetic Neural Retina by Modulating ACSL4.\nAbstract: Diabetic retinopathy (DR), a leading cause of vision impairment worldwide, is characterized by early neuronal damage in the retina, termed diabetic neuropathy in the retina (DNR). This condition is marked by neuronal apoptosis and glial activation. M\u00fcller glia are retinal cells highly susceptible to diabetic metabolic stress that may undergo ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation. However, the role of ferroptosis in DNR pathogenesis remains undefined. In this study, we investigated M\u00fcller cell injury under high-glucose and palmitic acid (HGP) conditions. The retinal tissues were obtained from normal rabbits and alloxan-induced diabetic rabbits. HGP exposure significantly reduced M\u00fcller cell viability, induced cell cycle arrest, and elevated proinflammatory cytokines. Ultrastructural analysis revealed mitochondrial damage, accompanied by decreased glutathione (GSH) and increased malondialdehyde (MDA), ferrous iron (Fe2+), and reactive oxygen species (ROS) levels. RNA sequencing (RNA-Seq) identified SQSTM1 as a ferroptosis-related differentially expressed gene, which was significantly upregulated in HGP-treated cells. In vivo, DNR rabbits exhibited oxidative stress, iron dysregulation, and elevated SQSTM1 expression that colocalized with GFAP+ M\u00fcller cells. Single-cell RNA-Seq of human proliferative diabetic retinopathy (PDR) retinas confirmed elevated SQSTM1 expression in M\u00fcller cells compared to healthy control (HC) retinas. Mechanistically, SQSTM1 knockdown attenuated ferroptosis, oxidative stress, and HGP-induced injury, while its overexpression exacerbated ferroptosis via ACSL4 upregulation. Overall, our findings suggest that SQSTM1 may serve as a critical mediator linking M\u00fcller cell dysfunction and ferroptosis in DNR pathogenesis, offering a novel potential therapeutic target.\n\nID: 40794446\nTitle: New Insights Into Diabetes-Induced Cell-Type-Specific Responses in the Neural Retina via Single-Cell Transcriptomics: A Report on Research Supported by Pathway to Stop Diabetes.\nAbstract: Diabetes triggers cell-type-specific responses in the retina, leading to vascular lesions, glial dysfunction, and neurodegeneration, all of which contribute to the progression of diabetic retinopathy (DR). However, the specific cell types involved in disease development and the molecular mechanisms driving their responses have not yet been fully clarified, impeding the creation of effective therapeutic strategies. Recent advancements in single-cell or single-nuclei transcriptomic technologies have provided a systematic approach to profile transcript-level alterations at single-cell resolution, allowing for an in-depth analysis of diabetes-induced retinal transcriptional changes across various animal models for DR. Here, in the context of research funded by the American Diabetes Association Pathway to Stop Diabetes program, we discuss the cell-type-specific responses in the neural retina identified through single-cell transcriptomic analyses. We emphasize new insights into neural retinal responses, potential therapeutic targets, and the limitations and unresolved topics that warrant further investigation. This article is part of a series of perspectives that report on research funded by the American Diabetes Association Pathway to Stop Diabetes program. Single-cell transcriptomics provides a powerful solution for dissecting diabetes-induced cell-type-specific responses in mammalian retina. This article summarizes key findings from recent single-cell transcriptomic studies regarding the mechanisms of diabetic retinopathy, with a particular emphasis on the neural retina. Specific retinal neuronal types/subtypes exhibit heightened sensitivity to diabetes at the transcriptional level. Retinal M\u00fcller glial cells are key contributors to diabetic retinopathy and promising therapeutic targets for retinal protection against diabetes.\n\nID: 40741597\nTitle: Ketosis-prone Diabetes as a Presentation of New-onset Diabetes in a Patient With Spinal Muscular Atrophy Type III.\nAbstract: Spinal muscular atrophy (SMA) is a genetic motor neuron disease that leads to reduced muscle mass and muscle weakness. Recent studies demonstrated that metabolic complications could develop as emerging complications among patients with SMA and long-term follow-up. Sarcopenia together with aberrant glucose and fatty acid metabolism can predispose those with SMA to develop diabetes and diabetic ketoacidosis. Here, we present a patient with SMA type III who presented with ketosis-prone diabetes as an initial presentation of diabetes. Pancreatic autoantibodies (anti-GAD and anti-IA2) and a monogenic diabetes genes panel revealed negative results. A polygenic risk score for type 2 diabetes revealed a low genetic risk for type 2 diabetes. After resolution of diabetic ketoacidosis, insulin therapy was successfully discontinued within 1 month after discharge and the patient has been treated with metformin in combination with thiazolidinedione. The possibility of metabolic abnormalities in patients with SMA should be considered among patients who live well into adulthood. Sarcopenia together with alterations in fatty acid and ketone metabolism could lead to ketosis-prone diabetes as an initial presentation of diabetes among patients with SMA.\n\nID: 40536048\nTitle: Establishment of a novel alloxan-induced rabbit model exhibiting unique diabetic retinal neuropathy features assessed via ERG + VEP.\nAbstract: Diabetic retinal neuropathy (DRN) leads to significant visual impairment; however, no existing animal model fully replicates its neural alterations, and inconsistent induction protocols with high mortality rates hinder long-term investigations. Adult male rabbits were randomly assigned to four experimental groups, each receiving a single intravenous injection of varying doses of alloxan and one control group. The safety and efficacy of alloxan in inducing diabetes were evaluated to determine the optimal dose. At 9\u2009weeks following injection with alloxan, retinal function was assessed using full-field electroretinography (ERG) and visual evoked potentials (VEPs). Retinal structure was examined in rabbits using spectral-domain optical coherence tomography (SD-OCT), Optos ultra-widefield (Optos UWF) false-color imaging, and widefield fundus fluorescein angiography (WF-FFA). Rabbits in the 80\u2009mg/kg alloxan group exhibited fewer complications, lower mortality, and a higher model success rate compared to other groups. At 9\u2009weeks post-injection, these rabbits demonstrated significantly elevated hemoglobin A1c and total cholesterol (p\u2009<\u20090.05) relative to controls. ERG revealed statistically significant reductions in oscillatory potential and b-wave amplitudes (p\u2009<\u20090.05), while VEP indicated decreased P2 amplitude (p\u2009<\u20090.001) and prolonged P2 latency (p\u2009<\u20090.05). SD-OCT, Optos UWF imaging, and WF-FFA demonstrated no significant changes in vascular abnormalities. Additionally, Hematoxylin and Eosin staining revealed retinal swelling (p\u2009<\u20090.05), and immunofluorescence confirmed glial activation and neuronal loss. A single intravenous injection of 80\u2009mg/kg alloxan effectively and safely induced DRN in rabbits, resulting in neural retina damage, thereby establishing this model as an ideal model for DRN research.\n\nID: 40530462\nTitle: Place of Death in Patients with Motor Neuron Disease and the Association with Comorbidities During the Coronavirus Disease 2019 Pandemic: A Population-Based Analysis.\nAbstract: ObjectiveMotor neuron disease (MND) is a progressive neurological disorder with no known cure that damages motor neurons. The purpose of this analysis is to examine the place of death for MND patients in the United States during the coronavirus disease 2019 (COVID-19) pandemic and to investigate the extent of specific comorbidities.MethodsWe obtained death certificate and associated comorbidities data for all U.S. MND deaths from 2018 to 2021 and conducted a population-based cross-sectional analysis of the deaths pre-COVID-19 (2018-2019) and during COVID-19 (2020-2021). We hypothesized that place of death and comorbidities associated with place of death for MND patients in the United States were altered during the COVID-19 pandemic in comparison to the 2 years period before the pandemic.ResultsWe analyzed 30\u2005066 MND deaths (14\u2005562 pre-COVID-19 and 15\u2005504 during COVID-19) aged 20 years and older. During COVID-19, MND deaths at home increased (54.4% vs 45.5% pre-COVID). Hispanic individuals had an increased likelihood of dying at home compared to a nursing home or hospice (OR\u2009=\u20091.57, 95%CI: 1.22-2.02), but a decreased likelihood compared to a hospital (OR\u2009=\u20090.61, 95% CI: 0.51-0.72). Among the top comorbidities listed, there was a 27.8% increase in diabetes mellitus and a 20.2% increase in essential hypertension during COVID-19. During COVID-19, diabetes mellitus was more commonly reported as a comorbidity for deaths occurring in hospitals (OR\u2009=\u20091.40, 95%CI: 1.03-1.89) or at home (OR\u2009=\u20091.26, 95%CI: 1.03-1.55), while essential hypertension was more commonly reported with deaths at home (OR\u2009=\u20091.17, 95%CI: 1.01-1.36).ConclusionOur analysis showed an increase in at-home MND deaths as well as certain comorbidities during the COVID-19 pandemic, suggesting MND patients had a higher likelihood of death from non-COVID-19 comorbidities.\n\nID: 40462740\nTitle: Red Blood Cell-Derived Exosomes as Mediators of Age-Related Neurodegeneration.\nAbstract: Age-associated neurodegenerative diseases (NDDs), including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis, are marked by progressive degeneration of the nervous system. Current diagnostic approaches, such as neuroimaging and cerebrospinal fluid biomarkers, are invasive, costly, and lack early diagnostic reliability. Recent studies highlight the potential of extracellular vesicles, particularly exosomes, derived from erythrocytes or red blood cells (RBCs), as emerging indicators of aging and age-associated diseases. Exosomes carry noncoding RNA, lipid, and protein molecules, and modulate cellular pathways at distant sites, providing neuroprotective and anti-inflammatory effects. In this study, we isolated RBC-derived exosomes of young and old mice. MicroRNA sequencing analysis revealed differential expression of several miRNA species between young and old mice. We report an upregulation of miR-125a-5p and a downregulation of miR-302a-5p in old mice that are potentially linked to neurodegenerative pathways. This study underscores the potential of RBC-derived exosomes as noninvasive biomarkers for NDDs.\n\nID: 40278411\nTitle: Lipid Metabolism and Statin Therapy in Neurodegenerative Diseases: An Endocrine View.\nAbstract: Background/aim: A growing body of evidence suggests a link between dyslipidemias and neurodegenerative diseases, highlighting the crucial role of lipid metabolism in the health of the central nervous system. The aim of our work was to provide an update on this topic, with a focus on clinical practice from an endocrinological point of view. Endocrinologists, being experts in the management of dyslipidemias, can play a key role in the prevention and treatment of neurodegenerative conditions, through precocious and effective lipid profile optimization. Methods: The literature was scanned to identify clinical trials and correlation studies on the association between dyslipidemia, statin therapy, and the following neurodegenerative diseases: Alzheimer's disease (AD), Parkisons's disease (PD), Multiple sclerosis (MS), and Amyotrophic lateral sclerosis (ALS). Results: Impaired lipid homeostasis, such as that frequently observed in patients affected by obesity and diabetes, is related to neurodegenerative diseases, such as AD, PD, and other cognitive deficits related to aging. AD and related dementias are now a real priority health problem. In the United States, there are approximately 7 million subjects aged 65 and older living with AD and related dementias, and this number is projected to grow to 12 million in the coming decades. Lipid-lowering therapy with statins is an effective strategy in reducing serum low-density lipoprotein cholesterol to normal range concentrations and, therefore, cardiovascular disease risk; moreover, statins have been reported to have a positive effect on neurodegenerative diseases. Conclusions: Several pieces of research have found inconsistent information following our review. There was no association between statin use and ALS incidence. More positive evidence has emerged regarding statin use and AD/PD. However, further large-scale prospective randomized control trials are required to properly understand this issue.\n\nID: 40037468\nTitle: 2024 VCP International Conference: Exploring multi-disciplinary approaches from basic science of valosin containing protein, an AAA+ ATPase protein, to the therapeutic advancement for VCP-associated multisystem proteinopathy.\nAbstract: Valosin-containing protein (VCP/p97) is a ubiquitously expressed AAA+ ATPase associated with numerous protein-protein interactions and critical cellular functions including protein degradation and clearance, mitochondrial homeostasis, DNA repair and replication, cell cycle regulation, endoplasmic reticulum-associated degradation, and lysosomal functions including autophagy and apoptosis. Autosomal-dominant missense mutations in the VCP gene may result in VCP-associated multisystem proteinopathy (VCP-MSP), a rare degenerative disorder linked to heterogeneous phenotypes including inclusion body myopathy (IBM) with Paget's disease of bone (PDB) and frontotemporal dementia (FTD) or IBMPFD, amyotrophic lateral sclerosis (ALS), Alzheimer's disease (AD), parkinsonism, Charcot-Marie Tooth disease (CMT), and spastic paraplegia. The complexity of VCP-MSP makes collaboration among stakeholders essential and necessitates a multi-disciplinary approach. The 2024 VCP International Conference was hosted at Caltech between February 22 and 25. Co-organized by Cure VCP Disease and Dr. Tsui-Fen Chou, the meeting aimed to center the patient as a research partner, harmonize diverse stakeholder engagement, and bridge the gap between basic and clinical neuroscience as it relates to VCP-MSP. Over 100 multi-disciplinary experts attended, ranging from basic scientists to clinicians to patient advocates. Attendees discussed genetics and clinical presentation, cellular and molecular mechanisms underlying disease, therapeutic approaches, and strategies for future VCP research. The conference included three roundtable discussions, 29 scientific presentations, 32 scientific posters, nine patient and caregiver posters, and a closing discussion forum. The following conference proceedings summarize these sessions, highlighting both the identified gaps in knowledge and the significant strides made towards understanding and treating VCP diseases.\n\nID: 39759580\nTitle: Association between cardiometabolic diseases and the risk and progression of motor neuron diseases in Sweden: a population-based case-control study.\nAbstract: The evidence on the link between cardiometabolic diseases (CMDs) and motor neuron diseases (MNDs) remains inconsistent. We aimed to determine whether there is an association of CMDs, namely, any cardiovascular disease, cardiac arrhythmia, heart failure, thromboembolic disease, hypertension, cerebrovascular disease, ischemic heart disease, diabetes mellitus type 2, and hypercholesterolemia with the risk and progression of MNDs. We included 1463 MND patients (amyotrophic lateral sclerosis (ALS), primary lateral sclerosis (PLS), progressive spinal muscular atrophy (PSMA), and unspecified MND) diagnosed from January 1, 2015, to July 1, 2023, in Sweden according to the Swedish Motor Neuron Disease Quality Registry (i.e., cases), up to 5 MND-free population controls per case (N\u00a0=\u00a07311) who were individually matched to the cases on age and sex, and the full siblings (N\u00a0=\u00a02002) and spouses (N\u00a0=\u00a01220) of MND patients (i.e., relative controls). Conditional logistic regression models were used to estimate the risk of MND diagnosis in relation to previous CMDs, through comparing MND patients to population controls or relative controls. MND patients were followed from diagnosis to assess the role of pre-diagnostic CMDs on disease progression. A joint longitudinal-survival model was used to estimate risk of mortality (or use of invasive ventilation) in relation to CMDs after taking into account the longitudinal changes of ALS functional rating scale-revised (ALSFRS-R) in the time-to-event analysis. Hierarchical clustering with the Ward's linkage and a dissimilarity matrix created by Gower's method was used to identify clusters of MND patients with distinct phenotypes. Among the CMDs studied, a history of diabetes mellitus type 2 (OR 0.75; 95% CI 0.62, 0.93) or hypercholesterolemia (OR 0.82; 95% CI 0.71, 0.94) more than one year before diagnosis was associated with a lower risk for MNDs. The associations persisted for more than five years before MND diagnosis. MND patients with a history of any cardiovascular disease (HR 1.43; 95% CI 1.13, 1.81), arrhythmia (HR 1.42; 95% CI 1.04, 1.93), heart failure (HR\u00a01.79; 95% CI 1.02, 3.14), hypertension (HR 1.41; 95% CI 1.12, 1.77), or hypercholesterolemia (HR 1.28; 95% CI 1.01, 1.62) had an increased mortality risk, compared to others, after taking into consideration the longitudinal changes in ALSFRS-R. Cluster analysis identified two clusters of MND patients, where one cluster demonstrated higher age, worse functional status, and higher prevalence of CMDs at the time of diagnosis as well as a higher mortality and faster functional decline during follow-up, compared to the ones included in the other cluster. Diabetes mellitus type 2 and hypercholesterolemia were associated with a lower future risk of MND. On the other hand, most of the CMDs were indicative of a poor disease progression after an MND diagnosis.

The application of MS-based proteomics advances our understanding of protein function, cellular signaling, and complex biological systems. MS data analysis is a critical process that includes identifying and quantifying proteins and peptides and then exploring their biological functions in downstream analyses. To address the complexities associated with MS data analysis, we developed ProtPipe to streamline and automate the processing and analysis of high-throughput proteomics and peptidomics datasets with DIA-NN preinstalled. The pipeline facilitates data quality control, sample filtering, and normalization, ensuring robust and reliable downstream analyses. ProtPipe provides downstream analyses, including protein and peptide differential abundance identification, pathway enrichment analysis, protein-protein interaction analysis, and major histocompatibility complex (MHC)-peptide binding affinity analysis. ProtPipe generates annotated tables and visualizations by performing statistical post-processing and calculating fold changes between predefined pairwise conditions in an experimental design. It is an open-source, well-documented tool available at https://github.com/NIH-CARD/ProtPipe, with a user-friendly web interface.\n\nID: 39478612\nTitle: Epidemiological characterization of rare diseases in Brazil: A retrospective\u00a0study of the Brazilian Rare Diseases Network.\nAbstract: The Brazilian Policy for Comprehensive Care for People with Rare Diseases was implemented in 2014; however, national epidemiological data on rare diseases (RDs) are scarce and mainly focused on specific disorders. To address this gap, University Hospitals, Reference Services for Neonatal Screening, and Reference Services for Rare Diseases, all of which are public health institutions, established the Brazilian Rare Diseases Network (RARAS) in 2020. The objective of this study was to perform a comprehensive nationwide epidemiological investigation of individuals with RDs in Brazil. This retrospective survey collected data from patients receiving care in 34 healthcare facilities affiliated with RARAS in 2018 and 2019. The survey included 12,530 participants with a median age of 15.0\u00a0years, with women representing 50.5% of the cohort. Classification according to skin color\u00a0demonstrated that 5044 (47.4%) participants\u00a0were admixed. Most had a confirmed diagnosis (63.2%), with a predominance of phenylketonuria (PKU), cystic fibrosis (CF), and acromegaly. Common clinical manifestations included global developmental delay and seizures. The average duration of the diagnostic odyssey was 5.4\u00a0years (\u00b1\u20097.9\u00a0years). Among\u00a0the confirmed diagnoses, 52.2% were etiological (biochemical: 42.5%; molecular: 30.9%), while 47.8% were clinical. Prenatal diagnoses accounted for 1.2%. Familial recurrence and consanguinity rates were 21.6% and 6.4%, respectively. Mainstay treatments included drug therapy (55.0%) and rehabilitation (15.6%). The Public Health System funded most diagnoses (84.2%) and treatments (86.7%). Hospitalizations were reported in 44.5% of cases, and the mortality rate was 1.5%, primarily\u00a0due to motor neuron disease and CF. This study marks a pioneering national-level data collection effort for rare diseases in Brazil, offering novel insights to advance the understanding, management, and resource allocation for RDs. It unveils an average diagnostic odyssey of 5.4\u00a0years and a higher prevalence of PKU and CF, possibly associated with the specialized services network, which included newborn screening services.\n\nID: 39462509\nTitle: A Million Person Study Innovation: Evaluating Cognitive Impairment and other Morbidity Outcomes from Chronic Radiation Exposure Through Linkages with the Centers for Medicaid and Medicare Services Assessment and Claims Data.\nAbstract: The study of One Million U.S. Radiation Workers and Veterans, the Million Person Study (MPS), examines the health consequences, both cancer and non-cancer, of exposure to ionizing radiation received gradually over time. Recently the MPS has focused on mortality patterns from neurological and behavioral conditions, e.g., Parkinson's disease, Alzheimer's disease, dementia, and motor neuron disease such as amyotrophic lateral sclerosis. A fuller picture of radiation-related late effects comes from studying both mortality and the occurrence (incidence) of conditions not leading to death. Accordingly, the MPS is identifying neurocognitive diagnoses from fee-for-service insurance claims from the Centers for Medicare and Medicaid Services (CMS), among Medicare beneficiaries beginning in 1999 (the earliest date claims data are available). Linkages to date have identified \u223c540,000 workers with available health information. Such linkages provide individual information on important co-factor and confounding variables such as smoking, alcohol consumption, blood pressure, obesity, diabetes and many other health and demographic characteristics. The total person-level set of time-dependent variables, outcomes, organ-specific dose measures, co-factors, and demographics will be massive and much too large to be evaluated with standard software. Thus, development of specialized open-source software designed for large datasets (Colossus) is nearly complete. The wealth of information available from CMS claims data, coupled with individual dose reconstructions, will thus greatly enhance the quality and precision of health evaluations for this new field of low-dose radiation and neurocognitive effects.\n\nID: 39453673\nTitle: Differential Effect of Aldosterone or Mineralocorticoid Receptor Overexpression on Retinal Inflammation.\nAbstract: Overactivation of the mineralocorticoid receptor (MR) pathway is proinflammatory and contributes to the pathogenesis of diabetic retinopathy and of age-related macular degeneration. Excess of aldosterone, the specific MR ligand, is known to stimulate the production of proinflammatory cytokines and chemokines in extrarenal tissues and cells. In the RPE/choroid complex, aldosterone upregulated genes encoding proteins of the inflammatory response and downregulated genes encoding proteins involved in synaptic activity and neurotransmitters. Yet, cortisol, which is the main MR ligand in the eye, is a potent anti-inflammatory endogenous glucocorticoid. The aim of the present work was to better understand the role of MR activation in retinal inflammation either by acute injection of aldosterone or overexpression of the receptor. We first analyzed the retinal transcriptomic regulation induced by acute intraocular injection of aldosterone in the rat. Then, we used a transgenic rat overexpressing human MR (hMR) to also conduct retinal transcriptomic analysis as well as histological evaluation of the retina, retinal pigment epithelium and choroid. Our results show that acute intravitreal injection of aldosterone is highly proinflammatory, upregulating pathways related to microglial activation, oxidative stress, cell death, and downregulating pathways related to glial/neuronal cells activity and proper neurotransmission. On the other hand, hMR overexpression mediates a low-grade inflammation in the retina, associated with notable choroidal inflammation and choroidal neuropathy. Consequences of hMR overexpression or aldosterone-injection on retinal transcriptome reveal very distinct pathological mechanisms, with only a few common genes regulated, most of them not being regulated in the same way. Although aldosterone is highly proinflammatory in the retina, MR overactivation in its physiologic milieu mediates a low-grade inflammation in the neural retina.\n\nID: 39328605\nTitle: Paraneoplastic Motor Neuron Disease in a Patient With Sigmoid Colon Adenocarcinoma: A Case Report.\nAbstract: Paraneoplastic neurological syndromes (PNS) are a rare and diverse group of disorders caused by immune-mediated effects of malignancies. These syndromes are very rare and often present diagnostic and therapeutic challenges. Motor neuron disease as a paraneoplastic condition is particularly uncommon, especially in association with gastrointestinal malignancies like sigmoid colon adenocarcinoma. A 62-year-old male with type 2 diabetes mellitus (T2DM) presented with chronic diarrhea and a three-year history of progressive bilateral limb weakness. Initial symptoms were attributed to diabetic neuropathy, but the rapid progression and severity warranted further investigation. Neurological examination revealed hypotonia, muscle wasting, and absent reflexes in all four limbs. Diagnostic tests, including electromyography (EMG) and nerve conduction studies, confirmed motor sensory axonal neuropathy. A colonoscopy revealed a mass in the sigmoid colon, and a biopsy confirmed adenocarcinoma. The patient was managed with surgical resection of the tumor, adjuvant chemotherapy, and immunomodulatory treatments, resulting in the stabilization of neurological symptoms. This case highlights the importance of considering paraneoplastic syndromes in patients with unexplained neurological symptoms, particularly when a malignancy is suspected or known. Early recognition and a multidisciplinary approach are crucial for improving patient outcomes. Further research is needed to understand the pathophysiological mechanisms and develop sensitive biomarkers for early detection.\n\nID: 39236857\nTitle: Dysfunctional mitochondria in age-related neurodegeneration: Utility of melatonin as an antioxidant treatment.\nAbstract: Mitochondria functionally degrade as neurons age. Degenerative changes cause inefficient oxidative phosphorylation (OXPHOS) and elevated electron leakage from the electron transport chain (ETC) promoting increased intramitochondrial generation of damaging reactive oxygen and reactive nitrogen species (ROS and RNS). The associated progressive accumulation of molecular damage causes an increasingly rapid decline in mitochondrial physiology contributing to aging. Melatonin, a multifunctional free radical scavenger and indirect antioxidant, is synthesized in the mitochondrial matrix of neurons. Melatonin reduces electron leakage from the ETC and elevates ATP production; it also detoxifies ROS/RNS and via the SIRT3/FOXO pathway it upregulates activities of superoxide dismutase 2 and glutathione peroxidase. Melatonin also influences glucose processing by neurons. In neurogenerative diseases, neurons often adopt Warburg-type metabolism which excludes pyruvate from the mitochondria causing reduced intramitochondrial acetyl coenzyme A production. Acetyl coenzyme A supports the citric acid cycle and OXPHOS. Additionally, acetyl coenzyme A is a required co-substrate for arylalkylamine-N-acetyl transferase, which rate limits melatonin synthesis; therefore, melatonin production is diminished in cells that experience Warburg-type metabolism making mitochondria more vulnerable to oxidative stress. Moreover, endogenously produced melatonin diminishes during aging, further increasing oxidative damage to mitochondrial components. More normal mitochondrial physiology is preserved in aging neurons with melatonin supplementation.\n\nID: 39009447\nTitle: Assembling a Coculture System to Prepare Highly Pure Induced Pluripotent Stem Cell-Derived Neurons at Late Maturation Stages.\nAbstract: Generation of human induced pluripotent stem cell (hiPSC)-derived motor neurons (MNs) offers an unprecedented approach to modeling movement disorders such as dystonia and amyotrophic lateral sclerosis. However, achieving survival poses a significant challenge when culturing induced MNs, especially when aiming to reach late maturation stages. Utilizing hiPSC-derived motor neurons and primary mouse astrocytes, we assembled two types of coculture systems: direct coculturing of neurons with astrocytes and indirect coculture using culture inserts that physically separate neurons and astrocytes. Both systems significantly enhance neuron survival. Compared with these two systems, no significant differences in neurodevelopment, maturation, and survival within 3\u2005weeks, allowing to prepare neurons at maturation stages. Using the indirect coculture system, we obtained highly pure MNs at the late mature stage from hiPSCs. Transcriptomic studies of hiPSC-derived MNs showed a typical neurodevelopmental switch in gene expression from the early immature stage to late maturation stages. Mature genes associated with neurodevelopment and synaptogenesis are highly enriched in MNs at late stages, demonstrating that these neurons achieve maturation. This study introduces a novel tool for the preparation of highly pure hiPSC-derived neurons, enabling the determination of neurological disease pathogenesis in neurons at late disease onset stages through biochemical approaches, which typically necessitate highly pure neurons. This advancement is particularly significant in modeling age-related neurodegeneration.\n\nID: 38968415\nTitle: Deciphering the Connection Between Microvascular Damage and Neurodegeneration in Early Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR), a common diabetes complication leading to vision loss, presents early clinical signs linked to retinal vasculature damage, affecting the neural retina at advanced stages. However, vascular changes and potential effects on neural cells before clinical diagnosis of DR are less well understood. To study the earliest stages of DR, we performed histological phenotyping and quantitative analysis on postmortem retinas from 10 donors with diabetes and without signs of DR (e.g., microaneurysms, hemorrhages), plus three control eyes and one donor eye with DR. We focused on capillary loss in the deeper vascular plexus (DVP) and superficial vascular plexus (SVP), and on neural retina effects. The eye with advanced DR had profound vascular and neural damage, whereas those of the 10 randomly selected donors with diabetes appeared superficially normal. The SVP was indistinguishable from those of the control eyes. In contrast, more than half of the retinas from donors with diabetes had capillary dropout in the DVP and increased capillary diameter. However, we could not detect any localized neural cell loss in the vicinity of dropout capillaries. Instead, we observed a subtle pan-retinal loss of inner nuclear layer cells in all diabetes cases (P < 0.05), independent of microvascular damage. In conclusion, our findings demonstrate a novel histological biomarker for early-stage diabetes-related damage in the human postmortem retina; the biomarker is common in people with diabetes before clinical DR diagnosis. Furthermore, the mismatch between capillary dropout and neural loss leads us to question the notion of microvascular loss directly causing neurodegeneration at the earliest stages of DR, so diabetes may affect the two readouts independently.\n\nID: 38960473\nTitle: Decoding genetic and pathophysiological mechanisms in amyotrophic lateral sclerosis and primary lateral sclerosis: A comparative study of differentially expressed genes and implicated pathways in motor neuron disorders.\nAbstract: Motor Neuron Disorders (MNDs), characterized by the degradation and loss of function of motor neurons, are recognized as fatal conditions with limited treatment options and no known cure. The present study aimed to identify the pathophysiological functions and affected genes in patients with MNDs, specifically Amyotrophic Lateral Sclerosis (ALS) and Primary Lateral Sclerosis (PLS). The GSE56808 dataset comprised three sample groups: six patients diagnosed with ALS (GSM1369650, GSM1369652, GSM1369654, GSM1369656, GSM1369657, GSM1369658), five patients diagnosed with PLS (GSM1369648, GSM1369649, GSM1369653, GSM1369655, GSM1369659), and six normal controls (GSM1369642, GSM1369643, GSM1369644, GSM1369645, GSM1369646, and GSM1369647). The application of computational analysis of microarray gene expression profiles enabled us to identify 346 significantly differentially expressed genes (DEGs), 169 genes for the ALS sample study, and 177 genes for the PLS sample study. Enrichment was carried out using MCODE, a Cytoscape plugin. Functional annotation of DEGs was carried out via ClueGO/CluePedia (v2.5.9) and further validated via the DAVID database. NRP2, SEMA3D, ROBO3 and, CACNB1, CACNG2 genes were identified as the gene of interest for ALS and PLS sample groups, respectively. Axonal guidance (GO:0007411) and calcium ion transmembrane transport (GO:0070588) were identified to be some of the significantly dysregulated gene ontology (GO) terms, with arrhythmogenic right ventricular cardiomyopathy (KEGG:05412) to be the top relevant KEGG pathway which is affected in MND patients. ROBO3 gene was observed to have distinctive roles in ALS and PLS-affected patients, hinting towards the differential progression of ALS from PLS. The insights derived from our comprehensive analysis accentuate the distinct variances in the underlying molecular pathogenesis of ALS and PLS. Further research should investigate the mechanistic roles of the identified DEGs and molecular pathways, leading to potential targeted therapies for ALS and PLS.\n\nID: 38891774\nTitle: Revisiting Glutamate Excitotoxicity in Amyotrophic Lateral Sclerosis and Age-Related Neurodegeneration.\nAbstract: Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disorder. While there are five FDA-approved drugs for treating this disease, each has only modest benefits. To design new and more effective therapies for ALS, particularly for sporadic ALS of unknown and diverse etiologies, we must identify key, convergent mechanisms of disease pathogenesis. This review focuses on the origin and effects of glutamate-mediated excitotoxicity in ALS (the cortical hyperexcitability hypothesis), in which increased glutamatergic signaling causes motor neurons to become hyperexcitable and eventually die. We characterize both primary and secondary contributions to excitotoxicity, referring to processes taking place at the synapse and within the cell, respectively. 'Primary pathways' include upregulation of calcium-permeable AMPA receptors, dysfunction of the EAAT2 astrocytic glutamate transporter, increased release of glutamate from the presynaptic terminal, and reduced inhibition by cortical interneurons-all of which have been observed in ALS patients and model systems. 'Secondary pathways' include changes to mitochondrial morphology and function, increased production of reactive oxygen species, and endoplasmic reticulum (ER) stress. By identifying key targets in the excitotoxicity cascade, we emphasize the importance of this pathway in the pathogenesis of ALS and suggest that intervening in this pathway could be effective for developing therapies for this disease.\n\nID: 38878106\nTitle: Lifestyle and medical conditions in relation to ALS risk and progression-an introduction to the Swedish ALSrisc Study.\nAbstract: This study was an introduction to the Swedish ALSrisc Study and explored the association of lifestyle and medical conditions, with risk and progression of amyotrophic lateral sclerosis (ALS). We included 265 newly diagnosed ALS patients during 2016-2022 in Stockholm and 207 ALS-free siblings and partners of the patients as controls. Information on body mass index (BMI), smoking, and history of head injuries, diabetes mellitus, hypercholesterolemia, and hypertension was obtained through the Euro-MOTOR questionnaire at recruitment. Patients were followed from diagnosis until death, invasive ventilation, or November 30, 2022. Higher BMI at recruitment was associated with lower risk for ALS (OR 0.89, 95%CI 0.83-0.95), especially among those diagnosed after 65\u00a0years. One unit increase in the average BMI during the 3 decades before diagnosis was associated with a lower risk for ALS (OR 0.94, 95%CI 0.89-0.99). Diabetes was associated with lower risk of ALS (OR 0.38, 95%CI 0.16-0.90), while hypercholesterolemia was associated with higher risk of ALS (OR 2.10, 95%CI 1.13-3.90). Higher BMI at diagnosis was associated with lower risk of death (HR 0.91, 95%CI 0.84-0.98), while the highest level of smoking exposure (in pack-years) (HR 1.90, 95%CI 1.20-3.00), hypercholesterolemia (HR 1.84, 95%CI 1.06-3.19), and hypertension (HR 1.76, 95%CI 1.03-3.01) were associated with higher risk of death, following ALS diagnosis. Higher BMI and diabetes were associated with lower risk of ALS. Higher BMI was associated with lower risk of death, whereas smoking (especially in high pack-years), hypercholesterolemia, and hypertension were associated with higher risk of death after ALS diagnosis.\n\nID: 38658168\nTitle: C9ORF72 Deficiency Results in Neurodegeneration in the Zebrafish Retina.\nAbstract: Hexanucleotide repeat expansions within the gene C9ORF72 are the most common cause of the neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). This disease-causing expansion leads to a reduction in C9ORF72 expression levels in patients, suggesting loss of C9ORF72 function could contribute to disease. To further understand the consequences of C9ORF72 deficiency in vivo, we generated a c9orf72 mutant zebrafish line. Analysis of the adult female spinal cords revealed no appreciable neurodegenerative pathology such as loss of motor neurons or increased levels of neuroinflammation. However, detailed examination of adult female c9orf72-/- retinas showed prominent neurodegenerative features, including a decrease in retinal thickness, gliosis, and an overall reduction in neurons of all subtypes. Analysis of rod and cone cells within the photoreceptor layer showed a disturbance in their outer segment structure and rhodopsin mislocalization from rod outer segments to their cell bodies and synaptic terminals. Thus, C9ORF72 may play a previously unappreciated role in retinal homeostasis and suggests C9ORF72 deficiency can induce tissue specific neuronal loss.\n\nID: 38581053\nTitle: Regulatory T cells limit age-associated retinal inflammation and neurodegeneration.\nAbstract: Ageing is the principal risk factor for retinal degenerative diseases, which are the commonest cause of blindness in the developed countries. These conditions include age-related macular degeneration or diabetic retinopathy. Regulatory T cells play a vital role in immunoregulation of the nervous system by limiting inflammation and tissue damage in health and disease. Because the retina was long-considered an immunoprivileged site, the precise contribution of regulatory T cells in retinal homeostasis and in age-related retinal diseases remains unknown. Regulatory T cells were selectively depleted in both young (2-4 months) and aged (18-23 months) FoxP3-DTR mice. We evaluated neuroretinal degeneration, gliosis, subretinal space phagocyte infiltration, and retinal pigmented epithelium morphology through immunofluorescence analysis. Subsequently, aged Treg depleted animals underwent adoptive transfer of both young and aged regulatory T cells from wild-type mice, and the resulting impact on neurodegeneration was assessed. Statistical analyses employed included the U-Mann Whitney test, and for comparisons involving more than two groups, 1-way ANOVA analysis followed by Bonferroni's post hoc test. Our study shows that regulatory T cell elimination leads to retinal pigment epithelium cell dysmorphology and accumulation of phagocytes in the subretinal space of young and aged mice. However, only aged mice experience retinal neurodegeneration and gliosis. Surprisingly, adoptive transfer of young but not aged regulatory T cells reverse these changes. Our findings demonstrate an essential role for regulatory T cells in maintaining age retinal homeostasis and preventing age-related neurodegeneration. This previously undescribed role of regulatory T cells in limiting retinal inflammation, RPE/choroid epithelium damage and subsequently photoreceptor loss with age, opens novel avenues to explore regulatory T cell neuroprotective and anti-inflammatory properties as potential therapeutic approaches for age-related retinal diseases.\n\nID: 38554281\nTitle: Depletion of Mettl3 in cholinergic neurons causes adult-onset neuromuscular degeneration.\nAbstract: Motor neuron (MN) demise is a hallmark of several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS). Post-transcriptional gene regulation can control RNA's fate, and defects in RNA processing are critical determinants of MN degeneration. N6-methyladenosine (m6A) is a post-transcriptional RNA modification that controls diverse aspects of RNA metabolism. To assess the m6A requirement in MNs, we depleted the m6A methyltransferase-like 3 (METTL3) in cells and mice. METTL3 depletion in embryonic stem cell-derived MNs has profound and selective effects on survival and neurite outgrowth. Mice with cholinergic neuron-specific METTL3 depletion display a progressive decline in motor behavior, accompanied by MN loss and muscle denervation, culminating in paralysis and death. Reader proteins convey m6A effects, and their silencing phenocopies METTL3 depletion. Among the m6A targets, we identified transactive response DNA-binding protein 43 (TDP-43) and discovered that its expression is under epitranscriptomic control. Thus, impaired m6A signaling disrupts MN homeostasis and triggers neurodegeneration conceivably through TDP-43 deregulation.\n\nID: 38551157\nTitle: Role of microglia/macrophage polarisation in intraocular diseases (Review).\nAbstract: Macrophages form a crucial component of the innate immune system, and their activation is indispensable for various aspects of immune and inflammatory processes, tissue repair, and maintenance of the balance of the body's state. Macrophages are found in all ocular tissues, spanning from the front surface, including the cornea, to the posterior pole, represented by the choroid/sclera. The neural retina is also populated by specialised resident macrophages called microglia. The plasticity of microglia/macrophages allows them to adopt different activation states in response to changes in the tissue microenvironment. When exposed to various factors, microglia/macrophages polarise into distinct phenotypes, each exhibiting unique characteristics and roles. Furthermore, extensive research has indicated a close association between microglia/macrophage polarisation and the development and reversal of various intraocular diseases. The present article provides a review of the recent findings on the association between microglia/macrophage polarisation and ocular pathological processes (including autoimmune uveitis, optic neuritis, sympathetic ophthalmia, retinitis pigmentosa, glaucoma, proliferative vitreoretinopathy, subretinal fibrosis, uveal melanoma, ischaemic optic neuropathy, retinopathy of prematurity and choroidal neovascularization). The paradoxical role of microglia/macrophage polarisation in retinopathy of prematurity is also discussed. Several studies have shown that microglia/macrophages are involved in the pathology of ocular diseases. However, it is required to further explore the relevant mechanisms and regulatory processes. The relationship between the functional diversity displayed by microglia/macrophage polarisation and intraocular diseases may provide a new direction for the treatment of intraocular diseases.\n\nID: 38467174\nTitle: Drp1-dependent mitochondrial fragmentation mediates photoreceptor abnormalities in type 1 diabetic retina.\nAbstract: Recent studies have highlighted that retinal neurodegeneration precedes microvascular changes in diabetic retinopathy (DR), but the specific mechanisms remain unclear. Given the pivotal role of dysfunctional mitochondria and oxidative stress in early DR, our objective was to observe mitochondria-related alterations in the neural retina of type one diabetic mellitus mice with no evidence of DR (T1DM-NDR). We aimed to identify the key mitochondrial-related proteins contributing to mitochondrial injury. Our study revealed that T1DM-NDR mice exhibited outer retina thinning, including the ellipsoid zone, inner segment, and outer segment. Additionally, there was an impaired amplitude of the b-wave in electroretinogram (ERG) and a disorganized arrangement of the photoreceptor layer. In both the retina of DM mice and high glucose (HG)-treated 661w cells, mitochondria appeared swollen and fragmented, with disrupted cristae, disorganized or shortened branches in the mitochondrial network, and decreased mitochondrial membrane potential. Among the mitochondrial-related proteins, dynamin-related protein 1 (Drp1) was upregulated, and the ratio of phosphorylated Drp1 protein at serine 616 (S616) and serine 637 (S637) sites significantly increased in the retina of DM mice. The administration of Mdivi-1 ameliorated high-glucose-induced dysfunctional mitochondria, thereby protecting T1DM-NDR mice retina from morphological and functional injuries. Our findings suggest that hyperglycemia promotes Drp1-mediated mitochondrial dysfunction, which may be a significant factor in the development of DR. The inhibition of high-glucose-induced mitochondrial fission emerges as a potential and innovative intervention strategy for preventing DR.\n\nID: 38313399\nTitle: Imaging Modalities for Assessing the Vascular Component of Diabetic Retinal Disease: Review and Consensus for an Updated Staging System.\nAbstract: To review the evidence for imaging modalities in assessing the vascular component of diabetic retinal disease (DRD), to inform updates to the DRD staging system. Standardized narrative review of the literature by an international expert workgroup, as part of the DRD Staging System Update Effort, a project of the Mary Tyler Moore Vision Initiative. Overall, there were 6 workgroups: Vascular Retina, Neural Retina, Systemic Health, Basic and Cellular Mechanisms, Visual Function, and Quality of Life. The Vascular Retina workgroup, including 16 participants from 4 countries. Literature review was conducted using standardized evidence grids for 5 modalities: standard color fundus photography (CFP), widefield color photography (WFCP), standard fluorescein angiography (FA), widefield FA (WFFA), and OCT angiography (OCTA). Summary levels of evidence were determined on a validated scale from I (highest) to V (lowest). Five virtual workshops were held for discussion and consensus. Level of evidence for each modality. Levels of evidence for standard CFP, WFCP, standard FA, WFFA, and OCTA were I, II, I, I, and II respectively. Traditional vascular lesions on standard CFP should continue to be included in an updated staging system, but more studies are required before they can be used in posttreatment eyes. Widefield color photographs can be used for severity grading within the area covered by standard CFPs, although these gradings may not be directly interchangeable with each other. Evaluation of the peripheral retina on WFCP can be considered, but the method of grading needs to be clarified and validated. Standard FA and WFFA provide independent prognostic value, but the need for dye administration should be considered. OCT angiography has significant potential for inclusion in the DRD staging system, but various barriers need to be addressed first. This study provides evidence-based recommendations on the utility of various imaging modalities for assessment of the vascular component of DRD, which can inform future updates to the DRD staging system. Although new imaging modalities offer a wealth of information, there are still major gaps and unmet research needs that need to be addressed before this potential can be realized.

The aim of our study was to analyze latency changes in a full-field electroretinogram (ERG) in patients with type 2 diabetes. This prospective study included 15 diabetic patients without DR, 16 diabetic patients with non-proliferative DR, 14 patients with pre-proliferative DR, 15 patients with proliferative DR, and 14 age-matched controls. All the participants underwent ophthalmologic examination and full-field ERGs. The ERGs were recorded with the Metrovision MonPackOne system. The latencies were analyzed for \"a\"- and \"b\"-waves in the dark-adapted (DA) 0.01 ERG, DA 3.0 ERG, DA oscillatory potentials, light-adapted (LA) 3.0 ERG, and 30 Hz flicker ERG. The delayed responses of healthy subjects compared to diabetic patients without DR were the DA oscillatory potentials (25.45 \u00b1 1.04 ms vs. 26.15 \u00b1 0.96 ms, p = 0.027). When comparing diabetic patients without DR and with non-proliferative DR, we did not obtain statistically significant delays. Significant delays in the DA 0.01 \"b\"-wave (61.91 \u00b1 5.52 ms vs. 66.36 \u00b1 8.12 ms, p = 0.029), DA 3.0 \"b\"-wave (41.01 \u00b1 2.50 ms vs. 44.16 \u00b1 3.78 ms, p = 0.035), and LA 3.0 \"a\"-wave (16.21 \u00b1 0.91 ms vs. 16.99 \u00b1 1.16 ms, p = 0.045) were found between non-proliferative DR and pre-proliferative DR. When comparing the groups of patients with pre-proliferative DR and proliferative DR, the LA 3.0 ERG \"b\"-wave (32. 63 \u00b1 2.53 ms vs. 36.19 \u00b1 3.21 ms, p < 0.0001), LA 30 Hz flicker ERG \"a\"-wave (19.56 \u00b1 3.59 vs. 21.75 \u00b1 4.74 ms, p= 0.025), and \"b\"-wave (32.23 \u00b1 4.02 vs. 36.68 \u00b1 3.48 ms, p = 0.017) were delayed. the electrophysiological findings from our study indicate that there is a substantial dysfunction of the neural retina in all stages of DR.\n\nID: 41488805\nTitle: Increased transmembrane protein 119 (TMEM119) levels in the cerebrospinal fluid of patients with mild cognitive impairment due to Alzheimer's disease suggest early microglial involvement.\nAbstract: We aimed to evaluate the potential of the microglial marker transmembrane protein 119 (TMEM119) in the cerebrospinal fluid (CSF) as a (differential) diagnostic biomarker for neurodegenerative diseases. Following assay validation, we used enzyme-linked immunosorbent assay to measure CSF TMEM119 in 174 patients from six diagnostic groups: Alzheimer's disease (AD, n\u00a0=\u00a035), amyotrophic lateral sclerosis (ALS, n\u00a0=\u00a033), cerebral microangiopathy (CM, n\u00a0=\u00a025), frontotemporal lobar degeneration (FTLD, n\u00a0=\u00a028), Lewy body diseases (n\u00a0=\u00a021), and non-neurodegenerative controls (n\u00a0=\u00a033). CSF TMEM119 levels were elevated in the AD group compared to the control (p\u00a0=\u00a00.004), CM (p\u00a0=\u00a00.005), and FTLD (p\u00a0=\u00a00.023) groups. Levels were higher in both mild cognitive impairment (MCI-AD) and dementia (ADD) subgroups when compared to controls. For the discrimination of AD from controls, the area under the curve (AUC) was 0.78. Our results indicate that CSF TMEM119 may have potential as a biomarker representing microglial involvement in early and later stages of AD. Elevated levels of TMEM119 were observed in the CSF of patients with AD.Increased CSF TMEM119 was seen in MCI-AD patients compared to controls.Elevated levels in MCI-AD underscore early microglial involvement in AD.In the AD group, an association was found between CSF TMEM119 and CSF total tau.CSF TMEM119 may provide valuable information on neuroinflammation.\n\nID: 41468784\nTitle: Neuropeptide Y at the crossroads of neurodegeneration: Mechanistic insights and emerging therapeutic strategies.\nAbstract: Neuropeptide Y (NPY), a widely distributed and highly conserved neuropeptide, plays a central role in the regulation of diverse physiological processes, including stress responses, energy homeostasis, vascular tone, and immune modulation, via activation of its receptor subtypes. Beyond its physiological roles, the dysregulation of NPY expression has been documented in several neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Machado-Joseph disease, and retinal disorders such as diabetic retinopathy and glaucoma. These alterations in NPY levels and receptor activity highlight its potential not only as a biomarker for disease progression but also as a promising therapeutic target. Previous evidence revealed that NPY exerts neuroprotection by alleviating excitotoxicity, oxidative stress, mitochondrial dysfunction, and neuroinflammation while concurrently facilitating neurogenesis, synaptic plasticity, and cellular resilience. NPY activates receptor-mediated intracellular signaling cascades like PI3K/Akt, MAPK/ERK, and p38K, that control cellular survival, proteostasis, and inflammation and thereby influence disease trajectories. Understanding NPY operation with these mechanisms can unveil new avenues for targeted therapy. Current insights into the complex roles of NPY in neurodegeneration are discussed in this review, and their implications in diagnostic and treatment strategies are addressed.\n\nID: 41169217\nTitle: Retinal proteomics in neurodegeneration: Insights into ocular and brain disorders.\nAbstract: Dysregulated proteome in the retina represents a promising avenue for discovering novel therapeutic targets and noninvasive diagnostic biomarkers for neurodegenerative diseases with ocular manifestations. Advanced mass spectrometry-based proteomics techniques have shown considerable potential in investigating the retinal proteome in diseases such as glaucoma, age-related macular degeneration, diabetic retinopathy, retinitis pigmentosa, as well as Alzheimer's disease, amyotrophic lateral sclerosis, and Parkinson's disease. Recent proteomics innovations are overcoming challenges such as limited sample size and protein coverage that previously hindered comprehensive retinal proteome analysis. Notably, the incorporation of artificial intelligence-driven computational pipelines, including Graphics Processing Unit-accelerated deep learning architectures, has markedly enhanced the precision and effectiveness of retinal proteomics. These advances facilitate high-resolution identification of novel protein signatures within large-scale multi-omics datasets. Furthermore, the integration of advanced artificial intelligence with state-of-the-art big data infrastructures supports the early detection of biomarkers and therapeutic targets in neurodegenerative diseases with ocular involvement, offering unprecedented disease specificity and sensitivity. In addition to these computational strides, emerging complementary and alternative technologies continue to provide valuable tools for retinal analysis, expanding the potential for identifying biomarker and therapeutic targets in both ophthalmic and neurodegenerative disorders. This review summarizes recent advancements in retinal proteomics, with a particular focus on neurodegenerative and ocular diseases.\n\nID: 40702789\nTitle: Synthetic microneurotrophins: Neurotrophin receptors for therapeutics of neurodegenerative diseases.\nAbstract: Neurodegenerative disorders are characterised by the chronic progressive degeneration of specific neuronal subtypes, neuroinflammation, myelin damage and synaptic loss. Despite their growing incidence, advancements in effective treatments remain limited, because of lack of knowledge for the aetiology of the diverse pathophysiology to design systematic therapies. Several studies highlight the role of neurotrophic factors (NTFs) as potential neuroprotective, regenerative therapies for these disorders. Although NTFs hold protective and regenerative potential for chronic neuroinflammatory and neurodegenerative conditions, major hurdles impair their clinical use, such as optimising the dosage of NTFs, minimising the invasiveness of delivery methods, overcoming blood-brain-barrier (BBB) impermeability and managing side effects. In the last two decades our group have synthesised and screened a large chemical library of steroidal analogues of dehydroepiandrosterone (DHEA), an endogenous steroid hormone, for their ability to mimic neurotrophin neuroprotective and neurogenic actions. Interestingly, DHEA was shown to interact with all neurotrophin receptors, acting most probably as an ancestral neurotrophin early in evolution. However, its chronic pharmacological use is questioned by its action as a major precursor of steroidogenesis. This review highlights the findings of numerous preclinical studies on these synthetic, non-toxic, BBB permeable DHEA derivatives, named microneurotrophins (MNTs), deprived of endocrine actions, activators of specific neurotrophin receptors. The multimodal actions of MNTs against neuronal death and activation of microglia, in addition to their beneficial effects in synaptogenesis and neurogenesis, place them as interesting lead molecules in the armamentarium of therapeutics for neurodegeneration.\n\nID: 40698100\nTitle: Ganglion Cell Layer Thickness as a Biomarker for Amyotrophic Lateral Sclerosis Functional Outcome: An OCT study.\nAbstract: This study aims to evaluate various optical coherence tomography (OCT) parameters in patients diagnosed with amyotrophic lateral sclerosis (ALS). Assessment of BCVA was done using Snellen charts, and subjective refraction was done to achieve a BCVA for distance and near. Measurement of intraocular pressure (IOP) was done with Goldman applanation tonometry. Stereoscopic fundus examination was performed using a 90D lens to assess the status of the optic nerve and retina, ruling out any ocular pathology. The patients were then subjected to OCT scanning to measure optic nerve head and macular parameters. Optical coherence tomography was performed using CIRRUS\u2122 HD OCT (500-21822) (version 8.0.0.518) (Carl Zeiss Meditec, Dublin, CA, USA). The analyzed area was centered manually, and the absence of segmentation errors was confirmed for each scan. RE Avg RNFL and LE Avg RNFL showed weak correlations with ALSFRS, indicated by Pearson Correlation coefficients of 0.073 and -0.026, respectively. The p-values (0.637 and 0.86) suggested that these correlations were not statistically significant. RE Avg GCL and LE Avg GCL, on the other hand, exhibited moderate positive correlations with ALSFRS scores, with correlation coefficients of 0.337 (RE) and 0.389 (LE). These correlations were statistically significant, as indicated by p-values of 0.021 and 0.006, respectively, suggesting a substantial association between GCL thickness and ALS functional outcomes. All patients in our study were clinically diagnosed cases of ALS, as per the El Escorial criteria. Age group-wise analysis showed statistically significant thinning overall as well as quadrant-wise RNFL parameters in patients less than 50 years compared to age-matched controls, indicating that the pathological process occurring in larger motor neurons in ALS might also be happening in smaller sensory neurons of the retina, causing thinning, which was not due to age-related process. Although GCIPL thinning was occurring in our cases, though statistically not significant compared to control, the significant positive correlation observed between GCIPL and ALS functional outcome and between RNFL and GCIPL measurements highlighted the fact that though the axonal degeneration in retinal neurons might not be translating to the same extent in ganglion cells in ALS, the subtle thinning of GCIPL correlated strongly with functional disability in patients with ALS, implying better functional scores with higher values of GCIPL parameters. In summary, GCL measurements in both eyes showed a notable relationship with ALSFRS, whereas RNFL did not appear to correlate significantly.\n\nID: 39971261\nTitle: Cdc42 is crucial for mural cell migration, proliferation and patterning of the retinal vasculature.\nAbstract: Mural cells constitute the outer lining of blood vessels and are essential for vascular development and function. Mural cell loss or malfunction has been associated with numerous diseases including diabetic retinopathy, stroke and amyotrophic lateral sclerosis. In this work, we investigate the role of CDC42 in mural cells in vivo, using the developing mouse retina as a model. In this study, we generated a mouse model for Cdc42 deletion in mural cells by crossing Pdgfrb-CreERT2 mice with Cdc42flox/flox mice. This model (Cdc42i\u0394MC) allowed us to investigate the role of CDC42 in pericytes and smooth muscle cells in the developing and adult retinal vasculature. We find that, during postnatal development, CDC42 is required in both, pericytes and smooth muscle cells to maintain proper cell morphology, mural cell coverage and distribution. During retinal angiogenesis, Cdc42-depleted pericytes lag behind the sprouting front and exhibit decreased proliferation. Consequently, capillaries at the sprouting front remain pericyte deprived, become dilated and are prone to increased vascular leakage. In addition, arteries and arterioles deviate from their normal growth directions and trajectory. While in the adult retina, mural cell coverage normalizes and pericytes adopt a normal morphology, smooth muscle cell morphologies remain abnormal and arteriolar branching angles are markedly reduced. Our findings demonstrate that CDC42 is required for mural cell migration and proliferation and suggest that mural cells are essential for normal morphogenesis and patterning of the developing retinal vasculature.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

The ubiquitin-proteasome system (UPS), a major pathway for selective intracellular protein degradation, is essential for maintaining neuronal protein homeostasis. Proteasome dysfunction has been implicated in several major neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and Huntington's disease (HD), although its extent and mechanisms vary across disease contexts. In this review, we examine current evidence for proteasome dysfunction in neurodegeneration and discuss how disease-associated proteins impair proteasome function through direct inhibition, defective substrate processing, and sequestration into protein aggregates. We also address the contribution of oxidative stress, neuroinflammation, and aging to proteasome dysregulation. Finally, we highlight emerging therapeutic strategies aimed at restoring proteasome function, including pharmacological activation, modulation of proteasome assembly and stability, and targeted protein degradation approaches. Understanding the context-dependent nature of proteasome dysfunction will be important for developing effective proteostasis-based therapies.\n  --- END ACTUAL ABSTRACT FOR 42450002 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis, are defined by progressive neuronal loss, protein misfolding, and chronic neuroinflammation, yet effective disease-modifying therapies remain absent.\" (Source: 42455475)\n- \"Diabetic retinal disease (DRD) has classically been defined as a microvascular complication of diabetes; however, the recent evidence highlighted the key role of neuronal degeneration during the earliest stages of its pathogenesis.\" (Source: 42353267)\n- \"Here, we synthesise emerging evidence supporting an integrated 'Autophagy-Senescence-Inflammasome (ASI) axis', in which reciprocal interactions among impaired autophagy, senescent glia, and inflammasome signalling establish a self-sustaining cycle of neuroinflammation.\" (Source: 42419491)\n- \"Neurofilament light chain (NfL) is a structural axonal protein measurable in CSF and blood, increasingly investigated as a biomarker of neuroaxonal injury in clinical and research contexts.\" (Source: 42474734)\n- \"Amyotrophic lateral sclerosis (ALS) is a progressive and fatal neurodegenerative disorder driven by neuroinflammation involving activated microglia and astrocytes, which accelerates the loss of motor neurons.\" (Source: 42469634)\n- \"Oxidative stress is a major contributor to retinal degeneration in ocular neurodegenerative diseases, including glaucoma, where the loss of retinal ganglion cells (RGCs) leads to vision loss.\" (Source: 42162725)\n- \"Reframing DR as a diabetes-driven disorder of early NVU uncoupling may help shift clinical thinking from late vascular rescue toward mechanism-based neurovascular protection, precision phenotyping, and stage-adapted intervention.\" (Source: 42460327)\n- \"The retina, an extension of the central nervous system, presents a unique opportunity for monitoring brain pathology due to its accessibility.\" (Source: 42217970)\n- \"DHE mitigates astrocyte-driven neurotoxicity associated with ALS/FTD-related RNA-binding protein pathology by suppressing inflammatory signaling and enhancing antioxidant defense mechanisms.\" (Source: 42458512)\n- \"Hyperglycemia is a key driver of neuroinflammation in DR.

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]\nDo any recent non-proliferative diabetic retinopathy clinical trials reveal anything about Amyotrophic Lateral Sclerosis?\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe query examines the potential overlap between clinical findings in non-proliferative diabetic retinopathy (NPDR) trials and amyotrophic lateral sclerosis (ALS). Based on the provided literature, there is no evidence identifying a recent NPDR clinical trial that investigates or reveals specific data concerning ALS. However, both conditions are characterized as neurodegenerative disorders sharing common pathological mechanisms, including neuroinflammation, mitochondrial dysfunction, and the potential utility of extracellular vesicles (EVs) as biomarkers.\n\n### [INTRODUCTION & JUSTIFICATION]\nCurrent scientific literature posits that diabetic retinopathy (DR) is increasingly classified as a neurovascular degenerative disorder, where neurodegenerative changes frequently precede clinically observable vascular lesions. Similarly, amyotrophic lateral sclerosis (ALS) is defined by progressive motor neuron loss involving chronic neuroinflammation and glial dysfunction. While the provided dataset discusses these pathologies as sharing underlying molecular vulnerabilities, it contains no reports of NPDR clinical trials that directly examine ALS. The integration of these fields is primarily found in the search for shared biomarkers, such as neurofilament light chain (NfL), and the investigation of common pathways like the \"Autophagy-Senescence-Inflammasome (ASI) axis.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Diabetic retinopathy and ALS share a reliance on the ubiquitin-proteasome system (UPS) for neuronal homeostasis; failure in this pathway is a common feature across major neurodegenerative diseases.\n*   Retinal pigment epithelium (RPE) cells in diabetes models demonstrate insulin secretion capabilities, suggesting a metabolic reprogramming analogous to processes involved in other neurodegenerative diseases.\n*   Extracellular vesicles (EVs) are identified as systemic mediators of communication between the retina and other tissues in diabetes, mirroring their role in spreading proteopathic seeds in ALS.\n*   C9ORF72 deficiency, the most common genetic cause of ALS, has been shown to induce tissue-specific neuronal loss in the zebrafish retina, including disturbances in outer segment structure.\n*   Mitochondrial aging and the production of reactive oxygen species (ROS) act as a central mechanistic hub for inflammation in both the neural retina and the CNS motor neurons.\n*   Both conditions feature sex-associated heterogeneity in their neuroinflammatory profiles, emphasizing the need for precision-based, sex-stratified clinical research.\n*   The cGAS-STING signaling pathway is increasingly implicated in both DR progression and ALS, representing a potential cross-disease therapeutic target for reducing neuroinflammation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

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

Mural cell loss or malfunction has been associated with numerous diseases including diabetic retinopathy, stroke and amyotrophic lateral sclerosis. In this work, we investigate the role of CDC42 in mural cells in vivo, using the developing mouse retina as a model. In this study, we generated a mouse model for Cdc42 deletion in mural cells by crossing Pdgfrb-CreERT2 mice with Cdc42flox/flox mice. This model (Cdc42i\u0394MC) allowed us to investigate the role of CDC42 in pericytes and smooth muscle cells in the developing and adult retinal vasculature. We find that, during postnatal development, CDC42 is required in both, pericytes and smooth muscle cells to maintain proper cell morphology, mural cell coverage and distribution. During retinal angiogenesis, Cdc42-depleted pericytes lag behind the sprouting front and exhibit decreased proliferation. Consequently, capillaries at the sprouting front remain pericyte deprived, become dilated and are prone to increased vascular leakage. In addition, arteries and arterioles deviate from their normal growth directions and trajectory. While in the adult retina, mural cell coverage normalizes and pericytes adopt a normal morphology, smooth muscle cell morphologies remain abnormal and arteriolar branching angles are markedly reduced. Our findings demonstrate that CDC42 is required for mural cell migration and proliferation and suggest that mural cells are essential for normal morphogenesis and patterning of the developing retinal vasculature."

Beyond its physiological roles, the dysregulation of NPY expression has been documented in several neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Machado-Joseph disease, and retinal disorders such as diabetic retinopathy and glaucoma. These alterations in NPY levels and receptor activity highlight its potential not only as a biomarker for disease progression but also as a promising therapeutic target. Previous evidence revealed that NPY exerts neuroprotection by alleviating excitotoxicity, oxidative stress, mitochondrial dysfunction, and neuroinflammation while concurrently facilitating neurogenesis, synaptic plasticity, and cellular resilience. NPY activates receptor-mediated intracellular signaling cascades like PI3K/Akt, MAPK/ERK, and p38K, that control cellular survival, proteostasis, and inflammation and thereby influence disease trajectories. Understanding NPY operation with these mechanisms can unveil new avenues for targeted therapy. Current insights into the complex roles of NPY in neurodegeneration are discussed in this review, and their implications in diagnostic and treatment strategies are addressed."

Since the retina is ontogenically brain-derived, we hypothesised that retinal biomarkers could be used, alone or in combination with other simple tests, to screen for MCI in people with diabetes. Baseline data from participants screened for RECOGNISED, a Horizon 2020-funded European project, were analysed. Main eligibility criteria for RECOGNISED included age \u226565 years, type 2 diabetes of over 5 years standing, no previous history of stroke or neurodegenerative disease, and no overt diabetic retinopathy or only mild-to-moderate non-proliferative diabetic retinopathy. Baseline characteristics of participants, including scores from the Montreal Cognitive Assessment test (MoCA) and Self-Administered Gerocognitive Examination, the Diabetes Specific Dementia Risk Score (DSDRS) and ophthalmological endpoints gathered from standardised seven field colour fundus photography, spectral domain optical coherence tomography, microperimetry and a hand-held portable electroretinography device (RETeval), were obtained and used in the work presented here as potential screening predictors for presence of MCI. MCI and normocognition (NC) were determined based on a full neuropsychological test battery and the Clinical Dementia Rating score. A stepwise selection of variables, based on Akaike's information criterion, and logistic regression models for predicting MCI were undertaken. Area under the receiver-operating characteristic curve analyses were used to predict the probability of the presence of MCI as well as sensitivity and specificity cut-off points. A total of 313 people living with diabetes (128 with NC and 185 with MCI) were included. People with diabetes with MCI were older (p=0.006) and had fewer years of education (p<0.001), lower retinal sensitivity (p=0.01) and less capacity of gaze fixation (p\u22640.001) than those with NC. Statistically significant differences in pupillary area ratio (p=0.002) and photopic b-wave amplitude (p=0.03) were detected between people with diabetes with NC and with MCI. Multivariable logistic regression showed that the best model to identify people with diabetes with MCI was that combining retinal sensitivity, gaze fixation, photopic b-wave amplitude and pupillary size change following stimulation, years of education, DSDRS and MoCA score, with an AUC of 0.84 (sensitivity 79.9, specificity 79.0). The visuo-construction domain was the most affected in people with diabetes with MCI and its impairment was independently related to retinal sensitivity and gaze fixation. The assessment of retinal neurodysfunction in combination with simple clinical variables appears useful to identify people with diabetes with MCI. This strategy could optimise current screening of MCI in people living with diabetes."

Here we show that SIRT1 levels are decreased and acetylated p53 levels are increased in iPSC-derived neurons from sALS patients and with the FTD3-causing CHMP2B mutation. Ectopic expression of SIRT1 in these patient neurons rescues neurodegeneration and reduces acetylated p53 levels. DNA damage is elevated in both sALS and FTD3 neurons, leading to increased phosphorylation of p53 at Serine 15 and elevated levels of Ku80. Knockdown of either p53 or Ku80 rescues neurodegeneration and increases SIRT1 levels in these neurons. Moreover, ectopic expression of SIRT1 or genetic knockdown of either p53 or Ku80 suppresses retinal neurodegeneration caused by FTD3-associated mutant CHMP2B protein in an in vivo Drosophila model. These findings identify a dysregulated SIRT1-p53 feedback loop as a common pathogenic mechanism and promising therapeutic target in both sporadic and familial ALS/FTD."

A peculiarity of the neurodegenerative processes is the variable susceptibility among distinct neuronal populations, exemplified by the contrasting resilience of motor neurons innervating the ocular motor system and the more vulnerable facial and hypoglossal motor neurons. The crucial role of vascular endothelial growth factor (VEGF) as a neuroprotective factor in the nervous system is well-established since a deficit of VEGF has been related to motoneuronal degeneration. In this study, we investigated the survival of ocular, facial, and hypoglossal motor neurons utilizing the murine SOD1G93A ALS model at various stages of the disease. Our primary objective was to determine whether the survival of the different brainstem motor neurons was linked to disparate VEGF expression levels in resilient and susceptible motor neurons throughout neurodegeneration. Our findings revealed a selective loss of motor neurons exclusively within the vulnerable nuclei. Furthermore, a significantly higher level of VEGF was detected in the more resistant motor neurons, the extraocular ones. We also examined whether TDP-43 dynamics in the brainstem motor neuron of SOD mice was altered. Our data suggests that the increased VEGF levels observed in extraocular motor neurons may potentially underlie their resistance during the neurodegenerative processes in ALS in a TDP-43-independent manner. Our work might help to better understand the underlying mechanisms of selective vulnerability of motor neurons in ALS."

This review aims to explore the use of blood-based NfL as an endpoint in clinical trials of neurodegenerative conditions. A database search of MEDLINE and EMBASE was conducted to identify interventional clinical trials and/or related post hoc analyses for neurodegenerative diseases, published between 2013 and 2024 that reported the use of serum or plasma NfL as an endpoint. Additional studies from reference lists of included trials were manually considered for inclusion where relevant. Data were charted descriptively by disease type and summarised. 49 studies were included, 29 in multiple sclerosis (MS), eight in amyotrophic lateral sclerosis (ALS), six in Alzheimer's disease (AD), and six in other diseases. Across studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response. However, several studies demonstrated a lack of concordance between change in NfL and in clinical outcomes, some of which may be related to the non-disease-modifying mechanisms of the interventions studied. This necessitates careful consideration when applying blood-based NfL as a biomarker endpoint for studies involving such interventions. Blood NfL is a promising biomarker with potential utility as a surrogate endpoint in neurological clinical trials, particularly for diseases with active axonal injury. Further validation, particularly around disease- and intervention-specific interpretation, is needed before blood NfL can be incorporated more routinely as a clinical endpoint."

This study identified elevated serum retinol-binding protein 4 (RBP4) as a risk factor for DR, because it induces retinal neuronal injuries and exacerbates vascular defects. Vitreous RBP4 levels were significantly elevated in patients with DR compared with those with macular disease. Elevated vitreous and serum RBP4 levels exacerbated hyperglycemia-induced endothelial inflammation, retinal vascular leakage, pericyte loss, and acellular capillaries in streptozotocin-induced diabetic mice. Progressive retinal degeneration and impaired electroretinography function were exhibited with RBP4 overexpression, likely through inducing retinal microglial activation and phagocytosis. Microglial depletion via PLX3397 (CSF-1R inhibitor) or inhibition using minocycline (anti-inflammatory tetracycline) significantly mitigated retinal degeneration in RBP4 transgenic (RBP4-Tg) mice. Furthermore, minocycline abolished the enhanced phagocytosis of zymosan in murine microglial BV2 cells induced by RBP4. The application of TAK242 or use of microglia-specific TLR4 knockout markedly reduced retinal neuroinflammation and degeneration in RBP4-Tg mice. Overall, these results suggest that elevated serum and vitreous RBP4 levels may be a risk factor for DR by exacerbating retinal neuronal and vascular injuries. Retinol-binding protein 4 (RBP4) levels are elevated in the vitreous humor of patients with diabetic retinopathy (DR) and in RBP4 transgenic mice. Elevated vitreous RBP4 exacerbates both vascular and neuronal deficits associated with DR in streptozotocin-induced diabetic mice. Hyperglycemia augments the RBP4-induced inflammatory response in retinal microvascular endothelial cells to exacerbate DR-related vascular pathologies. RBP4 triggers retinal microglial activation and phagocytosis via TLR4/nuclear factor-\u03baB/mitogen-activated protein kinase pathway, and microglial depletion or inhibition alleviates RBP4-induced retinal neurodegeneration."

It is caused primarily by pathogenic variants in the WFS1 gene, which encodes a transmembrane endoplasmic reticulum-resident protein involved in the unfolded protein response and cellular calcium homeostasis. Although multiple rodent models of Wolfram syndrome have been developed and shown to exhibit visual defects, some studies have reported significant vision loss prior to any detectable axonal degeneration or myelin abnormalities, and the mechanisms underlying these early visual deficits remain poorly understood. Recent in vitro studies have demonstrated altered synaptic contacts and aberrant neurite morphology in WFS1-deficient cerebral organoids and human iPSC-derived neurons, respectively. These findings prompted us to investigate, for the first time in vivo, whether synaptic and dendritic abnormalities occur in the retina of Wfs1 knockout mice. Using confocal microscopy, we examined retinal and optic nerve histology in Wfs1 knockout mice at 4 and 7 months of age. Our analysis reveals progressive synaptic alterations in the inner plexiform layer, driven by early presynaptic compartment failure. These changes represent the earliest detectable phenotype associated with vision loss in this model and precede overt axonal degeneration.

JNJ-TDP43-1 exhibited high binding affinity for pathological TDP-43 (Kd\u00a0=\u00a07.1\u00a0nM) and remarkable selectivity over other proteinopathies.

Common neurodegenerative disorders are Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), spinocerebellar ataxia (SCA), and supranuclear palsy. There is a lack of effective treatment for neurodegenerative diseases, and scientists are putting their efforts into developing therapies against them. Stem cell therapy has emerged as a hope for neurodegenerative disorders since it is not only the damaged neurons that might be replaced, but other neuromodulators and neuroprotectors are secreted. Stem cell terminal differentiation before implantation ensures the implantation of correct cells and molecular markers like carbonic anhydrase II, CNPase (2',3'-cyclic nucleotide 3'-phosphohydrolase), myelin basic protein (MBP), and myelin oligodendrocyte glycoprotein (MOG) elucidate the differentiation. Secretion of various growth factors like epidermal growth factor (EGF), keratinocyte growth factor (KGF), vascular endothelial growth factor-\u03b1 (VEGF-\u03b1), transforming growth factor (TGF), and macrophage inflammatory protein (MIP) supports cell survival, cell proliferation, blood vessel formation, axon regeneration, and neuroglial functional connection formation at the site of degeneration. Adverse effects of stem cell therapy, like teratogenicity and differentiation in different cells other than the desired one under the influence of microenvironment, are a few key concerns. Post-transplantation improved synaptic plasticity, apoptosis inhibition, and reduction in tau-phosphorylation and amyloid beta (A\u03b2) production has been observed in Alzheimer's patients. A large number of experimental, preclinical, and clinical studies have been conducted, and encouraging results have been obtained. The present review exhaustively discusses various kinds of stem cells, their usage in treating neurodegenerative disorders, limitations and challenges, and ethical issues related to stem cell therapy."

In this case-controlled biobank study, we aimed to ascertain differences in grey and white matter anatomy in people with DM compared with non-diabetic controls (NDC). This study utilises the UK Biobank prospective, population-based, multicentre study of UK residents. Participants with diabetes and age/gender-matched controls without diabetes were selected in a three-to-one ratio. We excluded people with underlying neurological/neurodegenerative disease. Whole brain, cortical, and subcortical volumes (188 regions) were compared between participants with diabetes against NDC corrected for age, sex, and intracranial volume using univariate regression models, with adjustment for multiple comparisons. Diffusion tensor imaging analysis of fractional anisotropy (FA) was performed along the length of 50 white matter tracts. We included 2404 eligible participants who underwent brain magnetic resonance imaging (NDC, n\u00a0=\u00a01803 and DM, n\u00a0=\u00a0601). Participants with DM had a mean (\u00b1standard deviation) diagnostic duration of 18\u00a0\u00b1\u00a011\u00a0years, with adequate glycaemic control (HbA1C 52\u00a0\u00b1\u00a013\u00a0mmol/mol), low prevalence of microvascular complications (diabetic retinopathy prevalence, 5.8%), comparable cognitive function to controls but greater self-reported pain. Univariate volumetric analyses revealed significant reductions in grey matter volume (whole brain, total, and subcortical grey matter), with mean percentage differences ranging from 2.2% to 7% in people with DM relative to NDC (all p\u00a0<\u00a00.0002). The subcortical (bilateral cerebellar cortex, brainstem, thalamus, central corpus callosum, putamen, and pallidum) and cortical regions linked to sensorimotor (bilateral superior frontal, middle frontal, precentral, and postcentral gyri) and visual functions (bilateral middle and superior occipital gyri), all had lower grey matter volumes in people with DM relative to NDC. People with DM had significantly reduced FA along the length of the thalamocortical radiations, thalamostriatal projections, and commissural fibres of the corpus callosum (all; p\u00a0<\u00a00\u00b7001). This analysis suggests that anatomic differences in brain regions are present in a cohort with adequately controlled glycaemia without prevalent microvascular disease when compared with volunteers without diabetes. We hypothesise that these differences may predate overt end-organ damage and complications such as diabetic neuropathy and retinopathy. Central nervous system alterations/neuroplasticity may occur early in the natural history of microvascular complications; therefore, brain imaging should be considered in future mechanistic and interventional studies of DM."

Early diagnosis remains challenging due to the absence of reliable and validated biomarkers. Calprotectin, a well-established inflammatory marker in various neuroinflammatory conditions, has paradoxically been found at reduced levels in the blood of ALS patients in a limited number of studies, raising the hypothesis of immune dysregulation rather than classical neuroinflammation. However, these findings are primarily derived from small patient cohorts and have yet to be independently replicated. This review critically assesses the emerging role of calprotectin in ALS by comparing it with other candidate biomarkers, including vascular endothelial growth factor (VEGF), apolipoprotein A1 (ApoA1), interleukin-8 (IL-8), interleukin-7 (IL-7), and interleukin-10 (IL-10). While calprotectin may reflect a distinct immunological profile, its standalone diagnostic value remains unclear. Nonetheless, its integration into a multi-analyte biomarker panel could enhance diagnostic precision and biological insight. The review also explores underlying immunological mechanisms, including receptor interactions (RAGE, TLR4, CD33), cellular mediators (microglia, lymphocytes, monocytes), and therapeutic implications. Future research should prioritize mechanistic investigation of calprotectin modulation in ALS, longitudinal validation in larger cohorts, and integration within multimodal biomarker frameworks. A better understanding of disease-specific immune alterations may contribute to earlier diagnosis, stratified patient monitoring, and targeted therapeutic development."

While anti-vascular endothelial growth factor (anti-VEGF) therapy, corticosteroids, laser photocoagulation, and vitreoretinal surgery have improved outcomes, none can permanently prevent disease progression. The complex pathophysiology of DR, which includes inflammation, oxidative stress, and neurodegeneration, highlights the need for additional systemic strategies. This narrative review was informed by a structured search of PubMed, Scopus, and Web of Science covering the period from January 2000 to September 10, 2025. Original studies, systematic reviews, and meta-analyses were included, whereas case reports and editorials were excluded. Findings were synthesized qualitatively. Preclinical models suggest that sodium-glucose cotransporter 2 (SGLT2) inhibitors exert neuroprotective, anti-inflammatory, and antioxidant effects on the retina, preserve the blood-retinal barrier, and reduce vascular endothelial growth factor (VEGF) expression. However, whether these retinal effects are only partially independent of glycemic control remains speculative, as clinical studies have not adequately controlled for changes in glycated hemoglobin (HbA1c) or for differences in concomitant glucose-lowering therapies. Observational clinical studies have associated SGLT2 inhibitor use with a lower risk of DR progression, a reduced incidence of proliferative DR, and fewer vision-threatening interventions compared with some other antihyperglycemic agents. Owing to the established indications in heart failure and chronic kidney disease associated with SGLT2 inhibitors, these agents appear promising for DR prevention and risk modification. However, current clinical evidence is based mainly on observational and retrospective studies and remains vulnerable to confounding and selection bias. Prospective randomized studies with ophthalmic endpoints are needed before firm conclusions can be drawn."

Although many existing reviews focus on the link between BBB disruption and neuronal degeneration in the brain, a similar analysis of the BRB integrity in retinal degeneration is currently unavailable. Like the BBB, the inner BRB is established by retinal blood vessels encapsulated in a neurovascular unit. The retinal neurovascular unit and BRB are affected not only in retina-specific neurodegenerative diseases (eg, diabetic retinopathy and retinitis pigmentosa) but also in neurodegenerative diseases that primarily affect the brain (eg, Alzheimer disease and Parkinson disease). In this review, the link between vascular abnormalities (including BRB disruption) and retinal neurodegeneration in these diseases will be discussed to highlight the pivotal role of BRB integrity in neuronal homeostasis and health."

Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface."

Its pathological mechanism is complex, involving the regulation of multiple processes such as abnormal neovascularization, nerve damage, oxidative stress, and chronic inflammation. As a key molecular mechanism for regulating protein function, post-translational modifications (PTMs) can dynamically modulate the activity and function of core cells (including retinal endothelial cells, M\u00fcller cells, and pericytes) and related signaling molecules including various forms (e.g., phosphorylation, glycosylation, acetylation, methylation, ubiquitination, and SUMOylation), thereby deeply participating in the pathological progression of DR. In addition, PTMs play a crucial role in the regulating signaling pathways, including PI3K/Akt, MAPK, AMPK, NF-\u03baB and JAK/STAT, in the development of DR. Moreover, increasing evidence demonstrates that targeting PTMs with small molecules, either as inhibitors or activators, can reverse protein misfolding and preserve neuroretinal integrity to halt the progression of DR. This review systematically summarizes the variation characteristics of different types of PTMs in DR, analyzes the involvement of PTMs on signaling cascade and cellular processes, reviews the association between ageing and PTMs, and sorts out the research progress of PTMs as potential diagnostic biomarkers and neuroprotective therapeutic targets for DR. It aims to offer a theoretical foundation for in-depth understanding of DR pathogenesis and the development of novel prevention and treatment strategies.\n\nID: 42431336\nTitle: Associationof Static and Dynamic Pupillary Abnormalities with Retinal Microvasculopathy and Neurodegeneration in Diabetics.\nAbstract: To investigate the characteristics of pupillary statics and dynamics and explore the relationship between pupillary abnormalities and microvascular as well as neurodegenerative changes of retina in the early stages of diabetes. This cross-sectional observational study included forty-eight diabetic subjects without diabetic retinopathy (NDR group), thirty-nine diabetic subjects with mild or moderate non proliferative diabetic retinopathy (DR group), and forty age- and sex-matched healthy adults (control group). Pupil size and pupillary light reflex were measured monocularly using a PLR-3000 dynamic pupillometer, and OCT/OCTA scans were acquired with a Van Gogh SS-OCTA device in all three groups. Both static and dynamic pupillary parameters differed significantly among the three groups (p <0.001). Pairwise comparisons showed that both basal and smallest pupil diameter were smaller in diabetes with or without retinopathy, compared to healthy control. Notably, pupillary dynamics didn't significantly reduce until retinopathy was present. Pupillary parameters showed a positive correlation with the thickness of the ganglion cell layer and inner plexiform layer in the parafovea, and the vessel density of the superficial vascular plexus and intermediate capillary plexus. Static pupillary abnormalities appear before clinical diabetic retinopathy. Both static and dynamic pupillary abnormalities worsen alongside retinal microvascular and neurodegenerative damages in the early stages of diabetes. Evaluation for autonomic nervous dysfunction is recommended for all patients with diabetic retinopathy.\n\nID: 42337644\nTitle: Outer nuclear layer thinning as an in vivo biomarker for discriminating probable FTLD-tau from probable FTLD-TDP with PET-supported subtyping.\nAbstract: Outer nuclear layer (ONL) thinning has been identified in frontotemporal lobar degeneration (FTLD); however, its utility for distinguishing the subtypes of FTLD-tauopathy (FTLD-tau) and TDP-43 proteinopathy (FTLD-TDP) remains unknown. We investigated whether ONL thickness provides a subtype-informative retinal signal for differentiating PET-supported probable FTLD-tau (pFTLD-tau) from probable FTLD-TDP (pFTLD-TDP) in vivo. Patients clinically diagnosed with FTLD were subtyped into pFTLD-tau and pFTLD-TDP groups based on multimodal PET and clinical criteria. Normal controls (NCs) were cognitively unimpaired on standardized testing and clinical evaluation. Macular images were acquired using swept-source OCT. A custom deep learning algorithm segmented the retina into eight sublayers. The thickness of each retinal sublayer was assessed across the eight sectors of the Early Treatment Diabetic Retinopathy Study (ETDRS) grid. Retinal thickness differences were analyzed using generalized estimating equations, and exploratory discrimination models were evaluated using age- and sex-adjusted stepwise logistic regression with apparent and bootstrap optimism-corrected AUCs reported. Exploratory partial correlation analysis was conducted to examine the associations between ONL thickness and cognitive scores. A total of 86 participants were included (21 pFTLD-tau, 27 pFTLD-TDP and 38 NCs). Widespread ONL thinning was observed in pFTLD-tau (Cohen's d= -0.753 to -1.268 vs. controls; -0.666 to -1.069 vs. pFTLD-TDP; all FDR-adjusted P\u2009<\u20090.05), while ONL in pFTLD-TDP remained preserved. A model combining retinal nerve fiber layer (RNFL), ONL, and myoid-ellipsoid zone (MEZ) thickness showed exploratory discrimination for differentiating pFTLD-tau from pFTLD-TDP (apparent AUC, 0.922; optimism-corrected AUC, 0.866). The outer thickness model yielded higher AUC estimates than the inner thickness model (0.884/0.835 vs. 0.713/0.630), and the individual ONL model showed moderate exploratory discrimination (0.808/0.765). ONL thickness was correlated with cognitive scores in pFTLD-tau (partial r\u2009=\u20090.433-0.483; all P\u2009<\u20090.05), whereas corresponding associations in pFTLD-TDP did not reach statistical significance. ONL thinning was preferentially observed in pFTLD-tau and contributed to exploratory discrimination between PET-supported probable FTLD subtypes. These findings suggest that ONL thickness may provide complementary, noninvasive information for probable FTLD subtype stratification, with potential to facilitate therapeutic trial enrollment and personalized management. Future studies incorporating neuropathological confirmation and fluid biomarkers are warranted to validate these findings.\n\nID: 42331015\nTitle: Malnutrition as a Risk Factor for Cerebral and Glaucomatous Neurodegeneration - Mechanisms and Therapeutic Strategies.\nAbstract: BACKGROUND: Neurodegenerative diseases are an increasing challenge for healthcare systems in the context of demographic change. They affect the central nervous system, including the brain-manifesting, for example, as dementia-as well as the retina, as seen in glaucoma or age-related macular degeneration. Malnutrition-defined as quantitative or qualitative under- or overnutrition-affects key mechanisms that contribute to neuronal and retinal neurodegeneration. OBJECTIVE: The aim of this study is to systematically present the pathophysiological mechanisms of malnutrition-related neurodegeneration, to evaluate the current evidence on dietary patterns and cognitive health, and to derive practical clinical strategies for nutritional optimization. METHODS: Narrative literature review based on peer-reviewed publications from the fields of nutritional medicine, geriatrics, neurology, ophthalmology, and public health. RESULTS: Malnutrition promotes oxidative stress, mitochondrial dysfunction, chronic neuroinflammation, and vascular dysregulation, and it influences neurotransmitter synthesis. These mechanisms are relevant to both cerebral and ocular neurodegenerative processes. The Mediterranean diet and the MIND diet are associated with a significantly reduced risk of cognitive impairment; for ocular diseases, interventional studies in age-related macular degeneration in particular demonstrate protective effects of antioxidant supplementation, whereas evidence for glaucoma is currently based predominantly on observational data. Screening approaches and micronutrient diagnostics enable early identification of at-risk individuals. Building on this, individualised dietary interventions and targeted supplementation of selected nutrients could be potentially preventive and stabilising therapeutic strategies. CONCLUSION: Malnutrition is a key modifiable risk factor for neurodegenerative diseases of the brain and retina. More intense integration of nutritional diagnostics and therapy into neurological, geriatric, and ophthalmological care structures appears warranted. Neurodegenerative Erkrankungen stellen angesichts des demografischen Wandels eine zunehmende Herausforderung f\u00fcr das Gesundheitswesen dar.

Despite advances in screening and treatment, including panretinal photocoagulation (PRP), intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents, and pars plana vitrectomy (PPV), outcomes remain heterogeneous: many eyes stabilise, whereas others progress to vitreous hemorrhage, tractional retinal detachment, or neovascular glaucoma despite apparently adequate therapy. This review synthesizes current knowledge on the pathophysiology, morphological phenotypes and treatment paradigms of PDR, with a specific focus on predictors of onset, progression, and recurrence. PDR is contextualised as a multifactorial neurovascular and inflammatory disease, integrating data on hypoxia-driven angiogenesis, glial activation, microvascular rarefaction, neurodegeneration, and vitreoretinal interface remodeling. Histopathological and multimodal imaging characteristics of neovascular complexes and the vitreoretinal interface are described, highlighting how phenotypes on color fundus photography, widefield fluorescein angiography, optical coherence tomography (OCT), and OCT angiography relate to ischemic burden and clinical behaviour. Systemic, ocular, imaging, biomarker, and genetic factors associated with progression from non-proliferative diabetic retinopathy to PDR and with progression within established PDR after PRP, anti-VEGF therapy, and PPV are critically appraised. Across modalities, younger age, diabetes duration, poor glycemic control, renal disease, extensive non-perfusion, high neovascular burden, complex fibrovascular proliferation, and incomplete or unsustained treatment consistently emerge as determinants of guarded outcomes. Outstanding gaps in mechanistic understanding, risk stratification, regenerative therapy, and implementation are identified, alongside a proposed research agenda aimed at delivering mechanistically grounded risk-prediction tools and disease-modifying interventions for PDR.\n\nID: 41791963\nTitle: Calprotectin as an immune-dysregulation biomarker in amyotrophic lateral sclerosis: Insights for diagnosis and therapy.\nAbstract: Motor neuron degeneration is a defining feature of amyotrophic lateral sclerosis (ALS), a progressive and fatal neurodegenerative disorder. Early diagnosis remains challenging due to the absence of reliable and validated biomarkers. Calprotectin, a well-established inflammatory marker in various neuroinflammatory conditions, has paradoxically been found at reduced levels in the blood of ALS patients in a limited number of studies, raising the hypothesis of immune dysregulation rather than classical neuroinflammation. However, these findings are primarily derived from small patient cohorts and have yet to be independently replicated. This review critically assesses the emerging role of calprotectin in ALS by comparing it with other candidate biomarkers, including vascular endothelial growth factor (VEGF), apolipoprotein A1 (ApoA1), interleukin-8 (IL-8), interleukin-7 (IL-7), and interleukin-10 (IL-10). While calprotectin may reflect a distinct immunological profile, its standalone diagnostic value remains unclear. Nonetheless, its integration into a multi-analyte biomarker panel could enhance diagnostic precision and biological insight. The review also explores underlying immunological mechanisms, including receptor interactions (RAGE, TLR4, CD33), cellular mediators (microglia, lymphocytes, monocytes), and therapeutic implications. Future research should prioritize mechanistic investigation of calprotectin modulation in ALS, longitudinal validation in larger cohorts, and integration within multimodal biomarker frameworks. A better understanding of disease-specific immune alterations may contribute to earlier diagnosis, stratified patient monitoring, and targeted therapeutic development.\n\nID: 41611978\nTitle: Relationship between retinal neurodysfunction and cognitive impairment in type 2 diabetes: results of the RECOGNISED cross-sectional study.\nAbstract: There are no robust, reliable and easy to administer tests to screen for mild cognitive impairment (MCI) in people living with diabetes. Since the retina is ontogenically brain-derived, we hypothesised that retinal biomarkers could be used, alone or in combination with other simple tests, to screen for MCI in people with diabetes. Baseline data from participants screened for RECOGNISED, a Horizon 2020-funded European project, were analysed. Main eligibility criteria for RECOGNISED included age \u226565 years, type 2 diabetes of over 5 years standing, no previous history of stroke or neurodegenerative disease, and no overt diabetic retinopathy or only mild-to-moderate non-proliferative diabetic retinopathy. Baseline characteristics of participants, including scores from the Montreal Cognitive Assessment test (MoCA) and Self-Administered Gerocognitive Examination, the Diabetes Specific Dementia Risk Score (DSDRS) and ophthalmological endpoints gathered from standardised seven field colour fundus photography, spectral domain optical coherence tomography, microperimetry and a hand-held portable electroretinography device (RETeval), were obtained and used in the work presented here as potential screening predictors for presence of MCI. MCI and normocognition (NC) were determined based on a full neuropsychological test battery and the Clinical Dementia Rating score. A stepwise selection of variables, based on Akaike's information criterion, and logistic regression models for predicting MCI were undertaken. Area under the receiver-operating characteristic curve analyses were used to predict the probability of the presence of MCI as well as sensitivity and specificity cut-off points. A total of 313 people living with diabetes (128 with NC and 185 with MCI) were included. People with diabetes with MCI were older (p=0.006) and had fewer years of education (p<0.001), lower retinal sensitivity (p=0.01) and less capacity of gaze fixation (p\u22640.001) than those with NC. Statistically significant differences in pupillary area ratio (p=0.002) and photopic b-wave amplitude (p=0.03) were detected between people with diabetes with NC and with MCI. Multivariable logistic regression showed that the best model to identify people with diabetes with MCI was that combining retinal sensitivity, gaze fixation, photopic b-wave amplitude and pupillary size change following stimulation, years of education, DSDRS and MoCA score, with an AUC of 0.84 (sensitivity 79.9, specificity 79.0). The visuo-construction domain was the most affected in people with diabetes with MCI and its impairment was independently related to retinal sensitivity and gaze fixation. The assessment of retinal neurodysfunction in combination with simple clinical variables appears useful to identify people with diabetes with MCI. This strategy could optimise current screening of MCI in people living with diabetes.\n\nID: 41515256\nTitle: Effects of a Red-Ginger-Based Multi-Nutrient Supplement on Optic Nerve Head Blood Flow in Open-Angle Glaucoma.\nAbstract: Objectives: Glaucoma is an age-related neurodegenerative disease, characterized by retinal ganglion cell loss and progressive visual field deterioration. Beyond intraocular pressure (IOP), vascular and metabolic dysregulation contributes to optic nerve head (ONH) ischemia and neuronal vulnerability. Nutritional factors with antioxidative and vasodilatory properties may help preserve ocular perfusion. This study investigated the acute and subacute effects of a single dose of a dietary supplement containing red ginger extract (Zingiber officinale var. rubra), lutein, and vitamin B6 on ONH blood flow in patients with open-angle glaucoma (OAG). Methods: A retrospective self-controlled study was conducted at Tohoku University Hospital between August 2023 and March 2025. ONH blood flow was quantified using a laser speckle flowgraphy (LSFG) baseline one hour after and one month after continuous oral supplementation in patients with OAG. Systemic parameters, ocular biometry, and concomitant glaucoma medications were recorded in medical charts. Relative mean blur rate (MBR) changes were analyzed using a linear mixed-effects model, accounting for repeated measures and inter-eye correlations. Results: Nineteen glaucoma patients (38 eyes) were included in the acute phase and 13 patients (26 eyes) completed the one-month follow-up. After adjusting for age and sex, a single oral dose of red ginger extract significantly increased the relative MBR at 1 h (106.9 \u00b1 3.1%; p < 0.05), and this enhancement increased after 1 month of continuous intake (115.4 \u00b1 6.7%; p < 0.05). Greater ONH perfusion was particularly prominent in eyes with shorter axial length. Conclusions: Oral supplementation was associated with acute and short-term increases in ONH blood flow in glaucomatous eyes. Although this study was a retrospective study without a placebo-controlled comparison group, our findings offer hypothesis-generating evidence that nutritional interventions may support ocular perfusion alongside conventional glaucoma management. Future prospective randomized controlled trials are required to confirm these associations.\n\nID: 41468784\nTitle: Neuropeptide Y at the crossroads of neurodegeneration: Mechanistic insights and emerging therapeutic strategies.\nAbstract: Neuropeptide Y (NPY), a widely distributed and highly conserved neuropeptide, plays a central role in the regulation of diverse physiological processes, including stress responses, energy homeostasis, vascular tone, and immune modulation, via activation of its receptor subtypes. Beyond its physiological roles, the dysregulation of NPY expression has been documented in several neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Machado-Joseph disease, and retinal disorders such as diabetic retinopathy and glaucoma. These alterations in NPY levels and receptor activity highlight its potential not only as a biomarker for disease progression but also as a promising therapeutic target. Previous evidence revealed that NPY exerts neuroprotection by alleviating excitotoxicity, oxidative stress, mitochondrial dysfunction, and neuroinflammation while concurrently facilitating neurogenesis, synaptic plasticity, and cellular resilience. NPY activates receptor-mediated intracellular signaling cascades like PI3K/Akt, MAPK/ERK, and p38K, that control cellular survival, proteostasis, and inflammation and thereby influence disease trajectories. Understanding NPY operation with these mechanisms can unveil new avenues for targeted therapy. Current insights into the complex roles of NPY in neurodegeneration are discussed in this review, and their implications in diagnostic and treatment strategies are addressed.\n\nID: 41422089\nTitle: The Ku80-p53-SIRT1 axis in DNA damage response contributes to sporadic and familial ALS and FTD.\nAbstract: Although TDP-43 pathology is found in most sporadic and familial ALS and FTD cases, other shared pathogenic mechanisms remain largely unknown. Here we show that SIRT1 levels are decreased and acetylated p53 levels are increased in iPSC-derived neurons from sALS patients and with the FTD3-causing CHMP2B mutation. Ectopic expression of SIRT1 in these patient neurons rescues neurodegeneration and reduces acetylated p53 levels. DNA damage is elevated in both sALS and FTD3 neurons, leading to increased phosphorylation of p53 at Serine 15 and elevated levels of Ku80. Knockdown of either p53 or Ku80 rescues neurodegeneration and increases SIRT1 levels in these neurons. Moreover, ectopic expression of SIRT1 or genetic knockdown of either p53 or Ku80 suppresses retinal neurodegeneration caused by FTD3-associated mutant CHMP2B protein in an in vivo Drosophila model. These findings identify a dysregulated SIRT1-p53 feedback loop as a common pathogenic mechanism and promising therapeutic target in both sporadic and familial ALS/FTD.\n\nID: 41409930\nTitle: Retinal Ganglion Cell Senescence Links Diabetes to Retinal Neurodegeneration.\nAbstract: Background Diabetic retinopathy (DR) is a leading cause of blindness worldwide and traditionally considered a microvascular complication. However, accumulating evidence indicates that retinal neurodegeneration is also crucial in DR pathogenesis. Retinal ganglion cells (RGCs), the output neurons of the retina, are particularly vulnerable to diabetic stress. Cellular senescence has been implicated in diabetes-related tissue damage, but its contribution to RGC degeneration remains unclear. We hypothesized that diabetes contributes to retinal neurodegeneration by inducing senescence in RGCs. Methods In streptozotocin (STZ)-induced diabetic mice, retinal function was assessed via full-field electroretinography (ERG), and molecular changes were evaluated in senescence markers. The expression of p16INK4a and monocyte chemotactic protein-1 (MCP-1) in retinal tissue was evaluated by enzyme-linked immunosorbent assay (ELISA) and quantitative real-time polymerase chain reaction (qRT-PCR), and the localization of p16INK4a was confirmed by immunostaining. To explore the direct effects of senescence, primary RGCs isolated from rat retina were exposed to oxidative stress or treated with the CDK4/6 inhibitor palbociclib. The isolated RGCs were analyzed via senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) staining and live-cell neurite imaging. Results The STZ-induced diabetic mice exhibited significant hyperglycemia without weight loss. ERG revealed markedly reduced amplitudes of the a-wave, b-wave, and oscillatory potentials, indicating impaired retinal neural function. Molecular analyses revealed significant upregulation of MCP-1 and p16INK4a at mRNA and protein levels. Immunostaining demonstrated p16INK4a co-expression in a subset of NeuN-positive cells within the ganglion cell layer, suggesting RGC senescence. Palbociclib-induced senescence (confirmed by SA-\u03b2-gal positivity) in vitroresulted in progressive neurite shortening in RGCs. Similarly, oxidative stress induced by antioxidant-free culture conditions caused neurite degeneration, highlighting the dual contributions of oxidative stress and senescence to RGC injury. Conclusions Cellular senescence was identified as a critical mechanism underlying RGC dysfunction in diabetes. Diabetes was found to induce retinal senescence and senescence-associated secretory phenotype activation, with RGCs exhibiting senescence-associated changes. Moreover, oxidative stress and pharmacologically induced senescence directly impaired RGC morphology and function in vitro. These results expanded our understanding of DR from a solely vascular disorder to a neurodegenerative disease, providing mechanistic insights into the role of senescence in retinal aging and neuronal susceptibility in diabetes.\n\nID: 41280004\nTitle: Riluzole as a Dual-Targeted Radiosensitizer for Osteosarcoma: Targeting Tumor Cells and Angiogenic Vasculature to Enhance Single High Dose Radiotherapy Efficacy.\nAbstract: Osteosarcoma is a highly aggressive bone malignancy primarily affecting children and young adults. It presents significant treatment challenges due to its inherent resistance to conventional fractionated radiotherapy (CFRT). Single high dose radiation therapy (SDRT) has promise for the treatment of radioresistant sarcomas, especially those characterized with extensive vascularity. However, its clinical application is severely constrained by toxicity to adjacent critical tissues. Radiosensitizers can enhance tumor cell susceptibility to radiation-induced DNA damage, improving therapeutic efficacy and potentially reducing collateral toxicity. Monotherapies targeting tumor vasculature alone in solid tumors have shown limited success as radiosensitizers in clinical settings. This highlights the importance of compounds that can simultaneously target both tumor cells and its associated microvasculature to maximize the therapeutic outcome to SDRT. Riluzole, the FDA-approved drug for Amyotrophic Lateral Sclerosis, is currently under investigation as a therapeutic agent for osteosarcoma. Riluzole acts to inhibit glutamate release, reduce glutathione levels in cancer cells, and mitigate tumor angiogenesis, positioning it as a potent radiosensitizing agent for the treatment of osteosarcoma. We hypothesize that Riluzole enhances osteosarcoma radiosensitivity to SDRT by simultaneously targeting intrinsic tumor radioresistance and pro-angiogenic signaling. Our findings demonstrate that Riluzole radiosensitizes osteosarcoma cells in vitro by reducing clonogenic survival and enhancing apoptosis. Mechanistically, Riluzole potentiates irradiation-induced reactive oxygen species (ROS) production, induces G2/M phase cell cycle arrest, inhibits DNA repair, and thereby amplifies radiation-induced DNA damage. Additionally, Riluzole suppresses radiation-induced Vascular Endothelial growth factor A (VEGFA) expression indicating its ability to overcome endothelial cell mediated radioresistance. Collectively, these results establish Riluzole as a promising radiosensitizer for osteosarcoma, with the potential to improve SDRT efficacy by overcoming both tumor-intrinsic and microvasculature-mediated radioresistance.\n\nID: 41228444\nTitle: Diet, Exercise, and Lifestyle in Glaucoma: Current Evidence and Future Perspectives.\nAbstract: Glaucoma is a major ocular neurodegenerative disease and a leading cause of irreversible blindness worldwide, with prevalence projected to exceed 110 million by 2040. Although lowering intraocular pressure (IOP) remains the only proven treatment, glaucoma arises from a complex interplay of genetic, local, and systemic factors-including oxidative stress, vascular dysregulation, mitochondrial dysfunction, and neuroinflammation. Emerging evidence suggests that modifiable lifestyle factors may influence these pathogenic pathways. In this review, higher dietary nitrate from leafy greens is consistently associated with lower primary open-angle glaucoma risk, aligning with nitric-oxide-mediated endothelial support and more stable ocular perfusion pressure. Flavonoids (anthocyanins and flavanols), carotenoids (lutein/zeaxanthin), and B vitamins have strong biological rationale for glaucoma prevention but have limited support from long-term, large population-based studies. The effect of polyunsaturated fats on glaucoma remains inconsistent and warrants source-(plant vs. animal) and substitution-based analyses. Consistent protective effects of aerobic exercise and high-quality sleep may be associated with favorable metabolic profiles and ocular perfusion, potentially mitigating retinal ganglion cell loss. Conversely, smoking and alcohol use are frequently coupled with poorer diet quality (e.g., lower vegetable intake) and heightened oxidative stress, which may exacerbate glaucomatous neurodegeneration. However, much of the current literature is constrained by cross-sectional designs, reliance on self-reported food frequency questionnaires, and insufficient use of structural endpoints such as retinal nerve fiber layer imaging. This review focuses on the potential of lifestyle modification and future directions in prevention and treatment strategies for glaucoma, highlighting the need for large-scale, multi-ethnic, genotype-stratified longitudinal studies and randomized controlled trials to establish causality and define optimal intervention strategies.\n\nID: 41169217\nTitle: Retinal proteomics in neurodegeneration: Insights into ocular and brain disorders.\nAbstract: Dysregulated proteome in the retina represents a promising avenue for discovering novel therapeutic targets and noninvasive diagnostic biomarkers for neurodegenerative diseases with ocular manifestations. Advanced mass spectrometry-based proteomics techniques have shown considerable potential in investigating the retinal proteome in diseases such as glaucoma, age-related macular degeneration, diabetic retinopathy, retinitis pigmentosa, as well as Alzheimer's disease, amyotrophic lateral sclerosis, and Parkinson's disease. Recent proteomics innovations are overcoming challenges such as limited sample size and protein coverage that previously hindered comprehensive retinal proteome analysis. Notably, the incorporation of artificial intelligence-driven computational pipelines, including Graphics Processing Unit-accelerated deep learning architectures, has markedly enhanced the precision and effectiveness of retinal proteomics. These advances facilitate high-resolution identification of novel protein signatures within large-scale multi-omics datasets. Furthermore, the integration of advanced artificial intelligence with state-of-the-art big data infrastructures supports the early detection of biomarkers and therapeutic targets in neurodegenerative diseases with ocular involvement, offering unprecedented disease specificity and sensitivity. In addition to these computational strides, emerging complementary and alternative technologies continue to provide valuable tools for retinal analysis, expanding the potential for identifying biomarker and therapeutic targets in both ophthalmic and neurodegenerative disorders. This review summarizes recent advancements in retinal proteomics, with a particular focus on neurodegenerative and ocular diseases.\n\nID: 41165792\nTitle: [Neurodegeneration and retinal changes-A\u00a0literature overview].\nAbstract: The eyes and the central nervous system (CNS) develop from the same embryonic tissue which explains why retinal changes have been observed in various neurological and neurodegenerative diseases. These changes can be visualized in vivo on a\u00a0cellular and subcellular level using optical coherence tomography (OCT). This article summarizes which retinal changes occur and how these could be used as potential biomarkers of neurodegenerative diseases. The article gives an overview of the literature on the relationship between neurodegeneration, OCT-based retinal characteristics and cognitive functions. A literature search was carried out in PubMed until February 2025. The search terms \"neurodegeneration\", \"dementia\", \"mild cognitive impairment\", \"mild neurocognitive disorder\", \"OCT\", \"OCT angiography (OCT-A)\", \"retinal biomarkers\", \"retinal layer\", \"RNFLT\", and \"GCL\" were used. Relevant publications were reviewed, analyzed and summarized. In OCT\u2011A Alzheimer's disease, frontotemporal dementia, vascular dementia, amyotrophic lateral sclerosis, multiple sclerosis (MS) and Parkinson's disease demonstrate an association with a\u00a0reduced retinal nerve fiber layer (RNFL) and the ganglion cell layer (GCL) thickness as well as an enlarged foveal avascular zone. So far retinal changes could not be specifically assigned to a\u00a0particular form of neurodegenerative disease,; however, they could be meaningful in neuropsychological/radiological examinations and for longitudinal monitoring, as already recommended for MS. Further longitudinal studies are needed to identify and validate retinal biomarkers (patterns). HINTERGRUND: Auge und Zentralnervensystem (ZNS) entwickeln sich aus demselben embryonalen Gewebe, weshalb Ver\u00e4nderungen der Retina bei verschiedenen neurologischen und neurodegenerativen Erkrankungen beobachtet werden. Diese k\u00f6nnen mithilfe der optischen Koh\u00e4renztomographie (OCT) auf zellul\u00e4rer und subzellul\u00e4rer Ebene in vivo dargestellt und vermessen werden. Welche retinalen Ver\u00e4nderungen auftreten, und wie diese als m\u00f6gliche Biomarker neurodegenerativer Erkrankungen zu nutzen w\u00e4ren, wird im vorliegenden Beitrag behandelt. \u00dcberblick \u00fcber die Literatur zur Beziehung zwischen Neurodegeneration, OCT-basierten retinalen Charakteristika und kognitiven Funktionen. In PubMed wurde eine Literaturrecherche bis Februar 2025 durchgef\u00fchrt, wobei die Suchbegriffe \u201eneurodegeneration\u201c, \u201edementia\u201c, \u201emild cognitive impairment\u201c, \u201emild neurocognitive disorder\u201c, \u201eOCT\u201c, \u201eOCT-Angiographie (OCT-A)\u201c, \u201eretinale Biomarker\u201c, \u201eretinale Schichten\u201c, \u201eRNFLT\u201c (\u201eretinal nerve fiber layer thickness\u201c) und \u201eGCL\u201c (\u201eganglion cell layer\u201c) verwendet wurden. Relevante Publikationen wurden gesichtet, analysiert und zusammengefasst. Alzheimer-, vaskul\u00e4re und frontotemporale Demenz sowie amyotrophe Lateralsklerose, multiple Sklerose (MS) und M.\u00a0Parkinson weisen in der OCT\u2011A eine Assoziation mit einer reduzierten RNFL und GCL-Dicke sowie einer vergr\u00f6\u00dferter fovealen avaskul\u00e4ren Zone auf. Bisher konnten retinale Ver\u00e4nderungen nicht spezifisch einer bestimmten neurodegenerativen Erkrankung zugeordnet werden. Im Rahmen von neuropsychologischen/-radiologischen Abkl\u00e4rungen und Verlaufsbeurteilungen k\u00f6nnten sie jedoch sinnvoll sein, wie bereits bei der MS empfohlen. Weitere longitudinale Studien sind erforderlich, um retinale Biomarker(-muster) zu identifizieren und zu validieren.\n\nID: 40802083\nTitle: Unveiling the limitations of OCT-based classification in diabetic epiretinal membranes: a call for integrative vascular and structural assessment with OCT-A.\nAbstract: Govetto's optical coherence tomography (OCT)-based staging system is widely used for idiopathic epiretinal membranes (ERMs), but its applicability to diabetic ERMs remains unclear. Given the distinct microvascular pathology in diabetes, this study evaluated the system's applicability in diabetic ERMs and compared structural and vascular features of diabetic and idiopathic ERMs using OCT and OCT-angiography (OCT-A). This retrospective study included 142 eyes with diabetic ERM, idiopathic ERM, and healthy controls. All subjects underwent comprehensive ophthalmic examination, OCT, and OCT-A imaging. ERMs were staged using Govetto et al.'s classification. Correlations between visual acuity (VA), ERM stage, OCT metrics, and OCT-A parameters were analyzed. The macular vessel density ratio (MVR) was also calculated. Ectopic inner foveal layer (EIFL), microcystoid changes, and retinal layer thicknesses were comparable across stages, with EIFL increasing as stages advanced in both groups. EIFL and outer foveal thickness showed no significant group differences, but EIFL was consistently thinner in diabetic cases. Diabetic ERMs had lower vessel densities (VD) and significantly reduced choriocapillaris flow area. Only in the diabetic group were strong correlations observed between outer retinal layer values and VD, as well as between VA, choriocapillaris flow, retinal thickness, and deep macular VD. Although Govetto's OCT-based classification aligns with structural progression in both ERM types, it does not reflect the vascular alterations seen in diabetic ERMs. These findings suggest that structural staging alone may be insufficient in diabetic cases. Awareness of vascular differences and integration of OCT-A parameters may improve interpretation and guide prognosis in diabetic ERMs.\n\nID: 40770000\nTitle: Glial fibrillary acidic protein in plasma and intraocular fluids and the correlation with cognitive function in patients with vitreoretinal disease.\nAbstract: Ocular imaging and fluid protein levels are emerging as biomarkers for neurodegenerative disease. Elevated levels of plasma glial fibrillary acidic protein (GFAP), a marker of astrogliosis, have been demonstrated early in the course of Alzheimer's Disease. In this study, we measured GFAP levels in the aqueous and vitreous humors and plasma of 79 participants undergoing vitrectomy surgery for retinal disease and correlated them with subject Mini Mental Status Exam (MMSE) and Trail Making Test part b (TMT-b) scores. Measured GFAP concentrations were higher in vitreous and aqueous than in plasma. Levels of GFAP within the aqueous and vitreous were correlated (r\u2009=\u20090.6; p\u2009<\u20090.0001); however, there was no association between GFAP levels in either ocular fluid and plasma. There was no significant correlation between GFAP levels in any of the measured ocular fluids and cognition as measured by MMSE and TMT-b scores. In plasma, higher GFAP levels were associated with lower TMT-b, but not MMSE, scores. Given that elevated GFAP levels are associated with a variety of vitreoretinal diseases, future studies evaluating its use as a potential biomarker for dementias should concentrate on recruiting subjects without a history of ocular disease.\n\nID: 40702789\nTitle: Synthetic microneurotrophins: Neurotrophin receptors for therapeutics of neurodegenerative diseases.\nAbstract: Neurodegenerative disorders are characterised by the chronic progressive degeneration of specific neuronal subtypes, neuroinflammation, myelin damage and synaptic loss. Despite their growing incidence, advancements in effective treatments remain limited, because of lack of knowledge for the aetiology of the diverse pathophysiology to design systematic therapies. Several studies highlight the role of neurotrophic factors (NTFs) as potential neuroprotective, regenerative therapies for these disorders. Although NTFs hold protective and regenerative potential for chronic neuroinflammatory and neurodegenerative conditions, major hurdles impair their clinical use, such as optimising the dosage of NTFs, minimising the invasiveness of delivery methods, overcoming blood-brain-barrier (BBB) impermeability and managing side effects. In the last two decades our group have synthesised and screened a large chemical library of steroidal analogues of dehydroepiandrosterone (DHEA), an endogenous steroid hormone, for their ability to mimic neurotrophin neuroprotective and neurogenic actions. Interestingly, DHEA was shown to interact with all neurotrophin receptors, acting most probably as an ancestral neurotrophin early in evolution. However, its chronic pharmacological use is questioned by its action as a major precursor of steroidogenesis. This review highlights the findings of numerous preclinical studies on these synthetic, non-toxic, BBB permeable DHEA derivatives, named microneurotrophins (MNTs), deprived of endocrine actions, activators of specific neurotrophin receptors. The multimodal actions of MNTs against neuronal death and activation of microglia, in addition to their beneficial effects in synaptogenesis and neurogenesis, place them as interesting lead molecules in the armamentarium of therapeutics for neurodegeneration.\n\nID: 40698100\nTitle: Ganglion Cell Layer Thickness as a Biomarker for Amyotrophic Lateral Sclerosis Functional Outcome: An OCT study.\nAbstract: This study aims to evaluate various optical coherence tomography (OCT) parameters in patients diagnosed with amyotrophic lateral sclerosis (ALS). Assessment of BCVA was done using Snellen charts, and subjective refraction was done to achieve a BCVA for distance and near. Measurement of intraocular pressure (IOP) was done with Goldman applanation tonometry. Stereoscopic fundus examination was performed using a 90D lens to assess the status of the optic nerve and retina, ruling out any ocular pathology. The patients were then subjected to OCT scanning to measure optic nerve head and macular parameters. Optical coherence tomography was performed using CIRRUS\u2122 HD OCT (500-21822) (version 8.0.0.518) (Carl Zeiss Meditec, Dublin, CA, USA). The analyzed area was centered manually, and the absence of segmentation errors was confirmed for each scan. RE Avg RNFL and LE Avg RNFL showed weak correlations with ALSFRS, indicated by Pearson Correlation coefficients of 0.073 and -0.026, respectively. The p-values (0.637 and 0.86) suggested that these correlations were not statistically significant. RE Avg GCL and LE Avg GCL, on the other hand, exhibited moderate positive correlations with ALSFRS scores, with correlation coefficients of 0.337 (RE) and 0.389 (LE). These correlations were statistically significant, as indicated by p-values of 0.021 and 0.006, respectively, suggesting a substantial association between GCL thickness and ALS functional outcomes. All patients in our study were clinically diagnosed cases of ALS, as per the El Escorial criteria. Age group-wise analysis showed statistically significant thinning overall as well as quadrant-wise RNFL parameters in patients less than 50 years compared to age-matched controls, indicating that the pathological process occurring in larger motor neurons in ALS might also be happening in smaller sensory neurons of the retina, causing thinning, which was not due to age-related process. Although GCIPL thinning was occurring in our cases, though statistically not significant compared to control, the significant positive correlation observed between GCIPL and ALS functional outcome and between RNFL and GCIPL measurements highlighted the fact that though the axonal degeneration in retinal neurons might not be translating to the same extent in ganglion cells in ALS, the subtle thinning of GCIPL correlated strongly with functional disability in patients with ALS, implying better functional scores with higher values of GCIPL parameters. In summary, GCL measurements in both eyes showed a notable relationship with ALSFRS, whereas RNFL did not appear to correlate significantly.\n\nID: 40536197\nTitle: Revolution of AAV in Drug Discovery: From Delivery System to Clinical Application.\nAbstract: Adeno-associated virus (AAV) is a non-enveloped DNA virus infecting a wide variety of species, tissues, and cell types, which is recognized as a safe and effective method for delivering therapeutic transgenes. AAV vector is the most popular viral gene delivery system in clinical delivery systems with unique and multiple advantages, such as tissue tropism, transduction specificity, long-lasting gene expression, low immune responses, and without host chromosome incorporation. Till now, four AAV-based gene therapy drugs have already been approved by the US Food and Drug Administration (FDA) or European Medicines Agency (EMA). Despite the success of AAV vectors, there are still some remaining challenges that limit further usage, such as poor packaging capacity, low organ specificity, pre-existing humoral immunity, and vector dose-dependent toxicity. In the present review, we address the different approaches to optimize AAV vector delivery system with a focus on capsid engineering, packaging capacity, and immune response at the clinical level. The review further investigates the potential of manipulating AAV vectors in preclinical applications and clinical translation, which emphasizes the challenges and prospects in viral vector selection, drug delivery strategies, immune reactions in cancer, neurodegenerative disease, retinal disease, SARS-CoV-2, and monkeypox. Finally, it forecasts future directions and potential challenges of artificial intelligence (AI), vaccines, and nanobodies, which emphasizes the need for ethical and secure approaches in AAV application.\n\nID: 39971261\nTitle: Cdc42 is crucial for mural cell migration, proliferation and patterning of the retinal vasculature.\nAbstract: Mural cells constitute the outer lining of blood vessels and are essential for vascular development and function. Mural cell loss or malfunction has been associated with numerous diseases including diabetic retinopathy, stroke and amyotrophic lateral sclerosis. In this work, we investigate the role of CDC42 in mural cells in vivo, using the developing mouse retina as a model. In this study, we generated a mouse model for Cdc42 deletion in mural cells by crossing Pdgfrb-CreERT2 mice with Cdc42flox/flox mice. This model (Cdc42i\u0394MC) allowed us to investigate the role of CDC42 in pericytes and smooth muscle cells in the developing and adult retinal vasculature. We find that, during postnatal development, CDC42 is required in both, pericytes and smooth muscle cells to maintain proper cell morphology, mural cell coverage and distribution. During retinal angiogenesis, Cdc42-depleted pericytes lag behind the sprouting front and exhibit decreased proliferation. Consequently, capillaries at the sprouting front remain pericyte deprived, become dilated and are prone to increased vascular leakage. In addition, arteries and arterioles deviate from their normal growth directions and trajectory. While in the adult retina, mural cell coverage normalizes and pericytes adopt a normal morphology, smooth muscle cell morphologies remain abnormal and arteriolar branching angles are markedly reduced. Our findings demonstrate that CDC42 is required for mural cell migration and proliferation and suggest that mural cells are essential for normal morphogenesis and patterning of the developing retinal vasculature.\n\nID: 39902055\nTitle: Semaglutide: Double-edged Sword with Risks and Benefits.\nAbstract: Type 2 Diabetes Mellitus therapy has evolved over the years to now include a new class of therapeutics, semaglutide. This article reviews the mechanism of action and formulation of semaglutide therapy, potential benefits, contraindications, adverse effects, and drug interactions. Oral and subcutaneous semaglutide therapies have shown effectiveness in improving glycemic control, weight loss, and reducing cardiovascular risks associated with diabetes mellitus. Semaglutide has also shown potential in being used as a therapeutic strategy in Alzheimer's disease due to its anti-neuroinflammatory effects and being used to treat polycystic ovary syndrome. However, semaglutide therapy is also associated with concerning adverse effects like acute pancreatitis, anesthetic risks like pulmonary aspiration or residual gastric content, acute kidney injury, acute gallbladder injury, nonarteritic anterior ischemic optic neuropathy and diabetic retinopathy. Contraindications of semaglutide include history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2, and pregnancy. Drug interactions to consider with semaglutide therapy include those also used in diabetes treatment, like metformin, as well as anti-psychotics, due to anti-psychotics associated weight gain. The findings of this article emphasize the need for a cross-disciplinary approach to understand the molecular mechanisms and clinical implications of semaglutide on patients with complex medical histories and treatment regimens. The potential anesthetic risks of semaglutide therapy warrant careful consideratiion with ethical concerns. Further studies can assess if there is a need to modify pre-operative guidelines to account for patient using semaglutide and how delayed gastric emptying and constitpation will affect surgical outcomes and complications. While semaglutide therapy for diabetes mellitus has been established, there is a need for extensive research on repurposing semaglutide in neurodegenerative disease treatment.\n\nID: 39778903\nTitle: Molecular Mechanisms of Vitamin E in Ocular Neurodegenerative Disorders: An Update on the Emerging Evidence and Therapeutic Implications.\nAbstract: Vitamin E is renowned for its potent antioxidant properties, crucial for shielding cells against oxidative stress and damage. Deficiency in this vitamin can lead to various health issues, including neurodegenerative diseases, due to its pivotal role in preserving cell membrane integrity and combating cellular oxidative damage. While its importance for overall health, including neurodegeneration, is acknowledged, the specific correlation between vitamin E deficiency and distinct ocular neurodegenerative disorders need to be further explored. This review delves into the molecular mechanisms of vitamin E in ocular neurodegenerative disorders; diabetic retinopathy, age-related macular degeneration, glaucoma, and cataracts, and emphasising the therapeutic implications drawn from existing evidence. Relationship between vitamin E and ocular neurodegenerative disorders is widely researched on, with its primary protective mechanisms attributed to its antioxidant and anti-inflammatory properties. However, studies on the supplementation of vitamin E among human subjects present mixed results, suggesting its complexities and variability depending on factors such as the specific disorder, disease stage, genetic differences, and form of vitamin E utilized. In conclusion, while vitamin E holds promise in mitigating ocular neurodegeneration through its antioxidant and anti-inflammatory properties, its supplementation's efficacy remains nuanced and context dependent. More research works are essential to elucidate its precise role and therapeutic potential in combating various ocular neurodegenerative disorders.\n\nID: 39705668\nTitle: Recent advances in stem cell therapy: efficacy, ethics, safety concerns, and future directions focusing on neurodegenerative disorders - a review.\nAbstract: Neurodegeneration refers to the gradual loss of neurons and extensive changes in glial cells like tau inclusions in astrocytes and oligodendrocytes, \u03b1-synuclein inclusions in oligodendrocytes and SOD1 aggregates in astrocytes along with deterioration in the motor, cognition, learning, and behavior. Common neurodegenerative disorders are Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), spinocerebellar ataxia (SCA), and supranuclear palsy. There is a lack of effective treatment for neurodegenerative diseases, and scientists are putting their efforts into developing therapies against them. Stem cell therapy has emerged as a hope for neurodegenerative disorders since it is not only the damaged neurons that might be replaced, but other neuromodulators and neuroprotectors are secreted. Stem cell terminal differentiation before implantation ensures the implantation of correct cells and molecular markers like carbonic anhydrase II, CNPase (2',3'-cyclic nucleotide 3'-phosphohydrolase), myelin basic protein (MBP), and myelin oligodendrocyte glycoprotein (MOG) elucidate the differentiation. Secretion of various growth factors like epidermal growth factor (EGF), keratinocyte growth factor (KGF), vascular endothelial growth factor-\u03b1 (VEGF-\u03b1), transforming growth factor (TGF), and macrophage inflammatory protein (MIP) supports cell survival, cell proliferation, blood vessel formation, axon regeneration, and neuroglial functional connection formation at the site of degeneration. Adverse effects of stem cell therapy, like teratogenicity and differentiation in different cells other than the desired one under the influence of microenvironment, are a few key concerns. Post-transplantation improved synaptic plasticity, apoptosis inhibition, and reduction in tau-phosphorylation and amyloid beta (A\u03b2) production has been observed in Alzheimer's patients. A large number of experimental, preclinical, and clinical studies have been conducted, and encouraging results have been obtained. The present review exhaustively discusses various kinds of stem cells, their usage in treating neurodegenerative disorders, limitations and challenges, and ethical issues related to stem cell therapy.\n\nID: 41532026\nTitle: Association between diabetic retinopathy and neurodegenerative diseases in the All of Us research program.\nAbstract: While diabetic retinopathy (DR) has previously been linked to neurodegenerative diseases, it remains unclear whether DR independently reflects neurodegenerative diseases beyond those attributable to diabetes itself. In this study, we leveraged data from the All of Us Research Program to assess whether DR serves as an independent marker of neurodegenerative disease among individuals with diabetes. A matched case-control, cross-sectional study was conducted using data from the All of Us Research Program (US-based EHR database). Three groups (exactly matched by age, sex, and race) were created and compared: individuals with both DR and DM (DR+DM, n = 7629), individuals with DM but no DR (DM-only, n = 22,887), and individuals without DM (n = 22,887). Outcomes included dementia, Alzheimer's disease (AD), Parkinson's disease (PD), and multiple sclerosis (MS). Univariate and multivariate logistic regression analyses were performed, adjusting for demographics, comorbidities and diabetes-related mediators. In multivariable analysis, DM-only was associated with increased odds of dementia (adjusted odds ratio [aOR] 1.28, 95 % CI: 1.08-1.51; p = 0.004). However, DR in the setting of DM (DM+DR vs. DM-only) was not associated with further increased odds of neurodegenerative disease outcome in multivariate models (aOR for dementia 1.18, 95 % CI: 0.94-1.49). No significant associations were identified for AD, PD, or MS (all p \u2265 0.10). Diabetic retinopathy was not associated with increased rates of neurodegenerative diseases beyond that conferred by diabetes itself, and the relationship may be mediated by diabetes severity and related comorbidities.\n\nID: 39446160\nTitle: Microvascular changes in eyes with non-proliferative diabetic retinopathy with or without macular microaneurysms: an OCT-angiography study.\nAbstract: To evaluate different quantitative non-invasive retinal biomarkers of microvascular impairment and neurodegeneration in patients affected by mild and moderate non proliferative diabetic retinopathy (NPDR) with or without macular microaneurysms (MAs). A cross-sectional case-control study. Ninety-seven eyes with NPDR, 49 with no central MAs and 48 with central MAs, underwent color fundus photography and optical coherence tomography (OCT)/OCT-angiography (OCT-A). Thickness of central macula, retinal nerve fiber layer (NFL), ganglion cell layer (GCL+) and NFL\u2009+\u2009GCL\u2009+\u2009was evaluated on OCT. FAZ metrics (ImageJ), perfusion and vessel density (PD/VD), and fractal dimension (FD) (MATLAB) were evaluated on 3\u2009\u00d7\u20093 OCT-A slabs of both superficial and deep capillary plexuses (SCP/DCP). All evaluations were performed on the full image and after subdivision in 4 quadrants. In the MA group, 77 MAs were detected (45.5% in the DCP). The MA group showed: increased FAZ area and perimeter in the SCP (p\u2009<\u20090.01) and DCP (p\u2009=\u20090.02), and reduced circularity index in the SCP (p\u2009=\u20090.03); reduced VD in the SCP (p\u2009<\u20090.01) and reduced PD, VD (p\u2009<\u20090.01) and FD (p\u2009=\u20090.02) in the DCP; decreased VD and FD in the SCP (p\u2009=\u20090.02 and p\u2009=\u20090.05), and in VD and FD in the DCP in the inferior quadrant (p\u2009=\u20090.04 and p\u2009=\u20090.03); a decrease in VD in the SCP in the nasal quadrant (p\u2009=\u20090.05). No differences have been detected in OCT parameters. Our results suggest that the presence of central MAs in patients with NPDR may correlate with more pronounced macular microvascular impairment, particularly during the mild and moderate stages of the disease.\n\nID: 39390534\nTitle: Is longer axial length protective of vision-threatening diabetic retinopathy across different ages? A multicenter cohort of 736 patients.\nAbstract: Vision-threatening diabetic retinopathy (VTDR) included severe non-proliferative diabetic retinopathy (NPDR), proliferative diabetic retinopathy (PDR) and clinically significant diabetic macular edema (DME). To compare the axial length (AL) and assess its influence on VTDR across different ages. A retrospective cohort study. Medical chart review was performed in 736 consecutive patients with VTDR. The patients were divided into young (\u2264\u200945\u00a0years) and elderly group (>\u200945\u00a0years) based on their age at the diagnosis of VTDR. After at least one year of standardized treatments, all eligible patients were followed up. The main outcome measures included the presence of tractional retinal detachment (TRD) involving foveal, final best-corrected visual acuity (BCVA), the development of neovascular glaucoma (NVG), and recurrent vitreous hemorrhage (VH) post-vitrectomy. ALs were compared between two age groups. The impact of AL on clinical outcomes was determined by logistic analyses after controlling for systemic parameters. The study included 144 patients\u2009\u2264\u200945\u00a0years and 592 patients\u2009>\u200945\u00a0years. Young patients had significantly longer AL than elderly participants (23.9\u00a0mm vs 23.0\u00a0mm, p\u2009<\u20090.001). Over a median follow-up of 25.9\u00a0months, a larger proportion of young patients developed TRD (34.7% vs 16.2%, p\u2009<\u20090.001) and recurrent VH (18.6% vs 10.3%, p\u2009=\u20090.040) than elderly patients. In elderly group, longer AL is an independent protective factor in preventing TRD (odds ratio [OR], 0.5; 95% confidence interval [CI], 0.4-0.7; P\u2009<\u20090.001). However, this beneficial effect was not observed in young patients. Young patients with VTDR exhibited significantly longer AL but more aggressive clinical signs with compromised prognosis. In elderly group, a longer AL independently reduced the risk of TRD, while this protective effect did not exist for young patients.\n\nID: 39232248\nTitle: Expanding the genotypic and phenotypic spectra with a novel variant in the ciliopathy gene, CFAP410, associated with selective cone degeneration.\nAbstract: CFAP410 (Cilia and Flagella Associated Protein 410) encodes a protein that has an important role in the development and function of cilia. In ophthalmology, pathogenic variants in CFAP410 have been described in association with cone rod dystrophy, retinitis pigmentosa, with or without macular staphyloma, or with systemic abnormalities such as skeletal dysplasia and amyotrophic lateral sclerosis. Herein, we report a consanguineous family with a novel homozygous CFAP410 c.335_346del variant with cone only degeneration and no systemic features. A retrospective analysis of ophthalmic history, examination, retinal imaging, electrophysiology and microperimetry was performed as well as genetic testing with in silico pathogenicity predictions and a literature review. A systemically well 28-year-old female of Pakistani ethnicity with parental consanguinity and no relevant family history, presented with childhood-onset poor central vision and photophobia. Best-corrected visual acuity and colour vision were reduced (0.5 LogMAR, 6/17 Ishihara plates (right) and 0.6 LogMAR, 3/17 Ishihara plates (left). Fundus examination showed no pigmentary retinopathy, no macular staphyloma and autofluorescence was unremarkable. Optical coherence tomography showed subtle signs of intermittent disruption of the ellipsoid zone. Microperimetry demonstrated a reduction in central retinal sensitivity. Electrodiagnostic testing confirmed a reduction in cone-driven responses. Whole-genome sequencing identified an in-frame homozygous deletion of 12 base pairs at c.335_346del in CFAP410. The non-syndromic cone dystrophy phenotype reported herein expands the genotypic and phenotypic spectra of CFAP410-associated ciliopathies and highlights the need for light of potential future genetic therapies.\n\nID: 39195519\nTitle: Metabolic Deficits in the Retina of a Familial Dysautonomia Mouse Model.\nAbstract: Neurodegenerative retinal diseases such as glaucoma, diabetic retinopathy, Leber's hereditary optic neuropathy (LHON), and dominant optic atrophy (DOA) are marked by progressive death of retinal ganglion cells (RGC). This decline is promoted by structural and functional mitochondrial deficits, including electron transport chain (ETC) impairments, increased oxidative stress, and reduced energy (ATP) production. These cellular mechanisms associated with progressive optic nerve atrophy have been similarly observed in familial dysautonomia (FD) patients, who experience gradual loss of visual acuity due to the degeneration of RGCs, which is thought to be caused by a breakdown of mitochondrial structures, and a disruption in ETC function. Retinal metabolism plays a crucial role in meeting the elevated energetic demands of this tissue, and recent characterizations of FD patients' serum and stool metabolomes have indicated alterations in central metabolic processes and potential systemic deficits of taurine, a small molecule essential for retina and overall eye health. The present study sought to elucidate metabolic alterations that contribute to the progressive degeneration of RGCs observed in FD. Additionally, a critical subpopulation of retinal interneurons, the dopaminergic amacrine cells, mediate the integration and modulation of visual information in a time-dependent manner to RGCs. As these cells have been associated with RGC loss in the neurodegenerative disease Parkinson's, which shares hallmarks with FD, a targeted analysis of the dopaminergic amacrine cells and their product, dopamine, was also undertaken. One dimensional (1D) proton (1H) nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry, and retinal histology methods were employed to characterize retinae from the retina-specific Elp1 conditional knockout (CKO) FD mouse model (Pax6-Cre; Elp1LoxP/LoxP). Metabolite alterations correlated temporally with progressive RGC degeneration and were associated with reduced mitochondrial function, alterations in ATP production through the Cahill and mini-Krebs cycles, and phospholipid metabolism. Dopaminergic amacrine cell populations were reduced at timepoints P30-P90, and dopamine levels were 25-35% lower in CKO retinae compared to control retinae at P60. Overall, this study has expanded upon our current understanding of retina pathology in FD. This knowledge may apply to other retinal diseases that share hallmark features with FD and may help guide new avenues for novel non-invasive therapeutics to mitigate the progressive optic neuropathy in FD.\n\nID: 38878068\nTitle: Associations of retinal neurovascular dysfunction with inner retinal layer thickness in non-proliferative diabetic retinopathy.\nAbstract: Neurovascular coupling impairment and inner retinal layer thinning are early detectable retinal changes in diabetes, and both worsen during progression of diabetic retinopathy (DR). However, direct interactions between these features have not been investigated so far. Therefore, we aimed to analyze associations between the retinal functional hyperemic response to light stimulation and the thickness of individual neuroretinal layers in eyes with early non-proliferative DR. Thirty patients with type 1 diabetes featuring mild (n\u2009=\u200915) or moderate (n\u2009=\u200915) non-proliferative DR and 14 healthy subjects were included in this cross-sectional study. Retinal vessel diameters were measured before and during illumination with flickering light using a dynamic vessel analyzer. Individual layer thickness in the macula was analyzed from spectral domain optical coherence tomography. Flicker light-induced vessel dilation was significantly reduced in patients compared to healthy controls (veins: 3.0% vs. 6.1%, p\u2009<\u20090.001; arteries: 1.3% vs. 5.1%, p\u2009=\u20090.005). Univariately, the response in retinal veins of diabetes patients correlated significantly with ganglion cell layer (GCL) thickness (r\u2009=\u20090.46, p\u2009=\u20090.010), and negatively with hemoglobin A1c (HbA1c) levels (r=-0.41, p\u2009=\u20090.023) and age (r=-0.38, p\u2009=\u20090.037), but not with baseline diameters, glucose levels, or diabetes duration. In a multiple regression model only GCL thickness (p\u2009=\u20090.017, \u03b2\u2009=\u20090.42) and HbA1c (p\u2009=\u20090.045, \u03b2=-0.35) remained significantly associated with the vascular flicker light response. The results indicate that thinner GCL and worse glycemic control both contribute to reduced retinal neurovascular coupling in patients with clinical signs of DR. Progression of neurovascular dysfunction in DR might be related to structural degeneration of the neurovascular complex in the inner retina.\n\nID: 38762243\nTitle: Tear biomarkers.\nAbstract: An extensive exploration of lacrimal fluid molecular biomarkers in understanding and diagnosing a spectrum of ocular and systemic diseases is presented. The chapter provides an overview of lacrimal fluid composition, elucidating the roles of proteins, lipids, metabolites, and nucleic acids within the tear film. Pooled versus single-tear analysis is discussed to underline the benefits and challenges associated with both approaches, offering insights into optimal strategies for tear sample analysis. Subsequently, an in-depth analysis of tear collection methods is presented, with a focus on Schirmer's test strips and microcapillary tubes methods. Alternative tear collection techniques are also explored, shedding light on their applicability and advantages. Variability factors, including age, sex, and diurnal fluctuations, are examined in the context of their impact on tear biomarker analysis. The main body of the chapter is dedicated to discussing specific biomarkers associated with ocular discomfort and a wide array of ocular diseases. From dry eye disease and thyroid-associated ophthalmopathy to keratoconus, age-related macular degeneration, diabetic retinopathy, and glaucoma, the intricate relationship between molecular biomarkers and these conditions is thoroughly dissected. Expanding beyond ocular pathologies, the chapter explores the applicability of tear biomarkers in diagnosing systemic diseases such as multiple sclerosis, amyotrophic lateral sclerosis, Alzheimer's disease, Parkinson's disease, and cancer. This broader perspective underscores the potential of lacrimal fluid analysis in offering non-invasive diagnostic tools for conditions with far-reaching implications.\n\nID: 38671842\nTitle: Progress in Understanding Oxidative Stress, Aging, and Aging-Related Diseases.\nAbstract: Under normal physiological conditions, reactive oxygen species (ROS) are produced through redox reactions as byproducts of respiratory and metabolic activities. However, due to various endogenous and exogenous factors, the body may produce excessive ROS, which leads to oxidative stress (OS). Numerous studies have shown that OS causes a variety of pathological changes in cells, including mitochondrial dysfunction, DNA damage, telomere shortening, lipid peroxidation, and protein oxidative modification, all of which can trigger apoptosis and senescence. OS also induces a variety of aging-related diseases, such as retinal disease, neurodegenerative disease, osteoarthritis, cardiovascular diseases, cancer, ovarian disease, and prostate disease. In this review, we aim to introduce the multiple internal and external triggers that mediate ROS levels in rodents and humans as well as the relationship between OS, aging, and aging-related diseases. Finally, we present a statistical analysis of effective antioxidant measures currently being developed and applied in the field of aging research.\n\nID: 38472048\nTitle: VEGF expression disparities in brainstem motor neurons of the SOD1G93A ALS model: Correlations with neuronal vulnerability.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rare neuromuscular disease characterized by severe muscle weakness mainly due to degeneration and death of motor neurons. A peculiarity of the neurodegenerative processes is the variable susceptibility among distinct neuronal populations, exemplified by the contrasting resilience of motor neurons innervating the ocular motor system and the more vulnerable facial and hypoglossal motor neurons. The crucial role of vascular endothelial growth factor (VEGF) as a neuroprotective factor in the nervous system is well-established since a deficit of VEGF has been related to motoneuronal degeneration. In this study, we investigated the survival of ocular, facial, and hypoglossal motor neurons utilizing the murine SOD1G93A ALS model at various stages of the disease. Our primary objective was to determine whether the survival of the different brainstem motor neurons was linked to disparate VEGF expression levels in resilient and susceptible motor neurons throughout neurodegeneration. Our findings revealed a selective loss of motor neurons exclusively within the vulnerable nuclei. Furthermore, a significantly higher level of VEGF was detected in the more resistant motor neurons, the extraocular ones. We also examined whether TDP-43 dynamics in the brainstem motor neuron of SOD mice was altered. Our data suggests that the increased VEGF levels observed in extraocular motor neurons may potentially underlie their resistance during the neurodegenerative processes in ALS in a TDP-43-independent manner. Our work might help to better understand the underlying mechanisms of selective vulnerability of motor neurons in ALS.\n\nID: 38387889\nTitle: Indirubin alleviates retinal neurodegeneration through the regulation of PI3K/AKT signaling.\nAbstract: Retinal neurodegenerative disease is a leading cause of blindness among the elderly in developed countries, including glaucoma, diabetic retinopathy, traumatic optic neuropathy and optic neuritis, etc. The current clinical treatment is not very effective. We investigated indirubin, one of the main bioactive components of the traditional Chinese medicine Danggui Longhui Pill, in the present study for its role in retinal neurodegeneration. Indirubin exhibited no detectable tissue toxicity in vivo or cytotoxicity in vitro. Moreover, indirubin improved visual function and ameliorated retinal neurodegeneration in mice after optic nerve crush injury in vivo. Furthermore, indirubin reduced the apoptosis of retinal ganglion cells induced by oxidative stress in vitro. In addition, indirubin significantly suppressed the increased production of intracellular reactive oxygen species and the decreased activity of superoxide dismutase induced by oxidative stress. Mechanically, indirubin played a neuroprotective role by regulating the PI3K/AKT/BAD/BCL-2 signaling. In conclusion, indirubin protected retinal ganglion cells from oxidative damage and alleviated retinal neurodegeneration induced by optic nerve crush injury. The present study provides a potential therapeutic medicine for retinal neurodegenerative diseases.\n\nID: 38363054\nTitle: Brain alterations in regions associated with end-organ diabetic microvascular disease in diabetes mellitus: A UK Biobank study.\nAbstract: Diabetes mellitus (DM) is associated with structural grey matter alterations in the brain, including changes in the somatosensory and pain processing regions seen in association with diabetic peripheral neuropathy. In this case-controlled biobank study, we aimed to ascertain differences in grey and white matter anatomy in people with DM compared with non-diabetic controls (NDC). This study utilises the UK Biobank prospective, population-based, multicentre study of UK residents. Participants with diabetes and age/gender-matched controls without diabetes were selected in a three-to-one ratio. We excluded people with underlying neurological/neurodegenerative disease. Whole brain, cortical, and subcortical volumes (188 regions) were compared between participants with diabetes against NDC corrected for age, sex, and intracranial volume using univariate regression models, with adjustment for multiple comparisons. Diffusion tensor imaging analysis of fractional anisotropy (FA) was performed along the length of 50 white matter tracts. We included 2404 eligible participants who underwent brain magnetic resonance imaging (NDC, n\u00a0=\u00a01803 and DM, n\u00a0=\u00a0601). Participants with DM had a mean (\u00b1standard deviation) diagnostic duration of 18\u00a0\u00b1\u00a011\u00a0years, with adequate glycaemic control (HbA1C 52\u00a0\u00b1\u00a013\u00a0mmol/mol), low prevalence of microvascular complications (diabetic retinopathy prevalence, 5.8%), comparable cognitive function to controls but greater self-reported pain. Univariate volumetric analyses revealed significant reductions in grey matter volume (whole brain, total, and subcortical grey matter), with mean percentage differences ranging from 2.2% to 7% in people with DM relative to NDC (all p\u00a0<\u00a00.0002). The subcortical (bilateral cerebellar cortex, brainstem, thalamus, central corpus callosum, putamen, and pallidum) and cortical regions linked to sensorimotor (bilateral superior frontal, middle frontal, precentral, and postcentral gyri) and visual functions (bilateral middle and superior occipital gyri), all had lower grey matter volumes in people with DM relative to NDC. People with DM had significantly reduced FA along the length of the thalamocortical radiations, thalamostriatal projections, and commissural fibres of the corpus callosum (all; p\u00a0<\u00a00\u00b7001). This analysis suggests that anatomic differences in brain regions are present in a cohort with adequately controlled glycaemia without prevalent microvascular disease when compared with volunteers without diabetes. We hypothesise that these differences may predate overt end-organ damage and complications such as diabetic neuropathy and retinopathy. Central nervous system alterations/neuroplasticity may occur early in the natural history of microvascular complications; therefore, brain imaging should be considered in future mechanistic and interventional studies of DM.\n\nID: 38255151\nTitle: Retinal Functional Impairment in Diabetic Retinopathy.\nAbstract: Diabetic retinopathy (DR) is a neurodegenerative disease of the retina. The aim of our study was to analyze latency changes in a full-field electroretinogram (ERG) in patients with type 2 diabetes. This prospective study included 15 diabetic patients without DR, 16 diabetic patients with non-proliferative DR, 14 patients with pre-proliferative DR, 15 patients with proliferative DR, and 14 age-matched controls. All the participants underwent ophthalmologic examination and full-field ERGs. The ERGs were recorded with the Metrovision MonPackOne system. The latencies were analyzed for \"a\"- and \"b\"-waves in the dark-adapted (DA) 0.01 ERG, DA 3.0 ERG, DA oscillatory potentials, light-adapted (LA) 3.0 ERG, and 30 Hz flicker ERG. The delayed responses of healthy subjects compared to diabetic patients without DR were the DA oscillatory potentials (25.45 \u00b1 1.04 ms vs. 26.15 \u00b1 0.96 ms, p = 0.027). When comparing diabetic patients without DR and with non-proliferative DR, we did not obtain statistically significant delays. Significant delays in the DA 0.01 \"b\"-wave (61.91 \u00b1 5.52 ms vs. 66.36 \u00b1 8.12 ms, p = 0.029), DA 3.0 \"b\"-wave (41.01 \u00b1 2.50 ms vs. 44.16 \u00b1 3.78 ms, p = 0.035), and LA 3.0 \"a\"-wave (16.21 \u00b1 0.91 ms vs. 16.99 \u00b1 1.16 ms, p = 0.045) were found between non-proliferative DR and pre-proliferative DR. When comparing the groups of patients with pre-proliferative DR and proliferative DR, the LA 3.0 ERG \"b\"-wave (32. 63 \u00b1 2.53 ms vs. 36.19 \u00b1 3.21 ms, p < 0.0001), LA 30 Hz flicker ERG \"a\"-wave (19.56 \u00b1 3.59 vs. 21.75 \u00b1 4.74 ms, p= 0.025), and \"b\"-wave (32.23 \u00b1 4.02 vs. 36.68 \u00b1 3.48 ms, p = 0.017) were delayed. the electrophysiological findings from our study indicate that there is a substantial dysfunction of the neural retina in all stages of DR.\n\nID: 38227526\nTitle: On implications of somatostatin in diabetic retinopathy.\nAbstract: Somatostatin, a naturally produced neuroprotective peptide, depresses excitatory neurotransmission and exerts anti-proliferative and anti-inflammatory effects on the retina. In this review, we summarize the progress of somatostatin treatment of diabetic retinopathy through analysis of relevant studies published from February 2019 to February 2023 extracted from the PubMed and Google Scholar databases. Insufficient neuroprotection, which occurs as a consequence of declined expression or dysregulation of retinal somatostatin in the very early stages of diabetic retinopathy, triggers retinal neurovascular unit impairment and microvascular damage. Somatostatin replacement is a promising treatment for retinal neurodegeneration in diabetic retinopathy. Numerous pre-clinical and clinical trials of somatostatin analog treatment for early diabetic retinopathy have been initiated. In one such trial (EUROCONDOR), topical administration of somatostatin was found to exert neuroprotective effects in patients with pre-existing retinal neurodysfunction, but had no impact on the onset of diabetic retinopathy. Overall, we concluded that somatostatin restoration may be especially beneficial for the growing population of patients with early-stage retinopathy. In order to achieve early prevention of diabetic retinopathy initiation, and thereby salvage visual function before the appearance of moderate non-proliferative diabetic retinopathy, several issues need to be addressed. These include the needs to: a) update and standardize the retinal screening scheme to incorporate the detection of early neurodegeneration, b) identify patient subgroups who would benefit from somatostatin analog supplementation, c) elucidate the interactions of somatostatin, particularly exogenously-delivered somatostatin analogs, with other retinal peptides in the context of hyperglycemia, and d) design safe, feasible, low cost, and effective administration routes.\n\nID: 37942487\nTitle: Efficacy of dual intracerebroventricular and intravitreal CLN5 gene therapy in sheep prompts the first clinical trial to treat CLN5 Batten disease.\nAbstract: Mutations in the CLN5 gene cause the fatal, pediatric, neurodegenerative disease CLN5 neuronal ceroid lipofuscinosis. Affected children suffer progressive neuronal loss, visual failure and premature death. Presently there is no treatment. This study evaluated dual intracerebroventricular (ICV) and intravitreal (IVT) administration of a self-complementary adeno-associated viral vector encoding ovine CLN5 (scAAV9/oCLN5) into CLN5 affected sheep (CLN5-/-) at various disease stages. CLN5 disease progression was slowed in pre-symptomatic sheep who received a moderate dose of scAAV9/oCLN5, whilst a higher ICV dose treatment in early and advanced symptomatic animals delayed or halted disease progression. Intracranial (brain) volume loss was attenuated in all treatment cohorts, and visual function was also sustained in both the early and advanced symptomatic treated sheep over the 24-month duration of the study. Robust CLN5 protein expression was detected throughout the brain and spinal cord, and improvements in central nervous system and retinal disease correlates were observed. These findings hold translational promise for extending and improving the quality of life in both pre-symptomatic and symptomatic CLN5 patients, and prompted the initiation of the first in-human Phase I/II clinical trial testing ICV/IVT administration of scAAV9 encoding human CLN5 (https://clinicaltrials.gov/; NCT05228145).\n\nID: 37916126\nTitle: Hyperlipidemia and lipid-lowering therapy in diabetic retinopathy (DR): A bibliometric study and visualization analysis in 1993-2023.\nAbstract: Diabetic retinopathy (DR) is a common complication in diabetic patients. DR is also a neurodegenerative disease. Patients with hyperglycemia, hyperlipidemia, and hypertension are vulnerable to retinopathy development. While the roles of blood glucose and blood pressure in the development of retinopathy have been extensively studied, the relationship between body fat and DR pathogenesis and the impact of lipid-reducing drugs on DR has just emerged as a research hotspot in DR study. We aim to visualize the contributions and cooperation of reporters, organizations, and nations, in addition to the research hotspots and trends in DR-related lipid research from 1993 to 2023, by bibliometric analysis. We extracted all publications about DR-related lipid research from 1993 to 2023 from the Web of Science Core Collection, and bibliometric features were studied using VOSviewer and the CiteSpace program. 1402 documents were retrieved. The number of studies has risen consistently for three decades, from an average of 16.8/year in the 1990s to 28.8/year in the 2000s, 64.5/year in 2010s, and reached 112/year in 2020-2022, confirming they are hot research topic in the field. These reports were from 93 nations/regions, with the USA, China, Japan, Australia, and England taking the leading positions. Diabetes Research and Clinical Practice was the journal that published the most studies, and Diabetes Care was the most quoted. We identified 6979 authors, with Wong TY having the most papers and being the most commonly co-cited. The most popular keyword, according to our research, is diabetic retinopathy. Oxidative stress, diabetic macular edema (DME), lipid peroxidation, and other topics have often been investigated. DR-related lipid research is conducted mainly in North America, Asia, Oceania, and Europe. Much study has centered on the relationship between lipid-lowering therapy and DR pathogenesis. These studies strongly support using lipid-reducing medications (fenofibrate, statins, and omega-3 PUFAs), combined with hyperglycemia and hypertension therapy, to prevent and treat DR. However, the impact of fenofibrate or statin on retinopathy is not correlated with their action on blood lipid profiles. Thus, more randomized clinical trials with primary endpoints related to DR in T1D or T2D are merited. In addition, the lipid biomarker for DR (lipid aldehydes, ALEs, and cholesterol crystals), the action of lipid-reducing medicines on retinopathy, the mechanism of lipid-lowering medications preventing or curing DR, and ocular delivery of lipid-lowering drugs to diabetic patients are predicted as the research focus in the future in the DR-related lipid research field.\n\nID: 42477295\nTitle: Ocular Manifestations of Metabolic Syndrome: A Systemic Vascular Phenotype.\nAbstract: Metabolic syndrome (MetS) is defined by central obesity, insulin resistance, hypertension and dyslipidemia. MetS affects over one-third of US adults. Beyond its cardiovascular burden, MetS has clinically relevant associations with ocular health and may contribute to a systemic vascular and neuro-metabolic phenotype involving the retina, optic nerve, lens, ocular surface and choroid. This narrative review searched PubMed through May 2026 using combinations of free-text and MeSH-based terms related to 'metabolic syndrome', 'insulin resistance', 'obesity', 'hypertension', 'dyslipidemia', 'diabetes', 'diabetic retinopathy', 'diabetic macular edema', 'glaucoma', 'cataract', 'dry eye', 'macular degeneration', 'retinal vascular occlusion' and 'optic neuropathy'. Reference lists of relevant reviews and primary studies were also screened. English-language human, translational, epidemiologic, clinical-trial, systematic-review and meta-analysis articles were prioritized. This was not designed as a systematic review, and formal PRISMA screening, risk-of-bias grading and meta-analysis were not performed. MetS and its components are associated with diabetic retinopathy, diabetic macular edema (DME), non-diabetic retinopathy, primary open-angle glaucoma, cataract, dry eye disease, age-related macular degeneration (AMD), retinal vascular occlusions and non-arteritic anterior ischemic optic neuropathy (NAION). Shared mechanisms include chronic inflammation, oxidative stress, endothelial dysfunction, insulin resistance-driven retinal neurodegeneration, dyslipidemia-related lipotoxicity, hypertension-related microvascular injury and microvascular rarefaction. Management requires both systemic risk-factor optimization and disease-specific ophthalmic therapy, including anti-VEGF therapy, intraocular pressure reduction, laser or surgical procedures when indicated, ocular surface-directed therapy and cataract surgery when visually significant. Ocular complications associated with MetS are common and may be vision-threatening. Risk-based ocular surveillance and metabolic optimization are justified, particularly in patients with diabetes, hypertension, dyslipidemia, visual symptoms or established vascular disease. However, the strength of disease-specific evidence varies: interventional evidence is strongest for diabetic retinopathy risk reduction and glaucoma treatment through intraocular pressure lowering, whereas evidence for AMD, NAION, RVO, cataract and dry eye disease is more frequently observational or indirect.\n\nID: 42472726\nTitle: Apolipoprotein E \u03b54 and type 2 diabetes cooperatively accelerate amyloid beta and tau neurodegeneration.\nAbstract: Both type 2 diabetes mellitus (T2DM) and Apolipoprotein E (APOE) \u025b4 allele are recognized risk factors for Alzheimer's disease (AD). However, the impact of the APOE \u025b4 allele on the accumulation of AD-related neuropathology in patients with T2DM remains unclear. We analyzed amyloid beta (A\u03b2) and tau deposition patterns via positron emission tomography (PET) imaging in 163 T2DM patients (64 \u025b4 carriers) and 1654 normal glucose metabolism subjects (687 \u025b4 carriers). Findings reveal that A\u03b2 deposition has a broader range of influence in diabetics carrying the \u025b4 allele, especially in the deep cortical areas. In terms of tau accumulation, diabetic carriers exhibit progression to the posterior and frontal cortices. Specifically, a greater A\u03b2 PET burden is associated with higher levels of plasma A\u03b242 and lower levels of cerebrospinal fluid (CSF) A\u03b242, A\u03b242/40, and A\u03b242/38. A significant positive correlation was observed between tau PET burden and CSF tau and phosphorylated tau (pTau), and plasma pTau181. Importantly, higher A\u03b2 and tau standardized uptake value ratio were associated with poorer memory performance and lower scores on the Montreal Cognitive Assessment. These findings highlight the allele's region-specific synergism with T2DM in driving AD-related pathology, potentially informing the development of a neuroimaging-based grading system to evaluate diabetic neuropathology severity and progression dynamics.\n\nID: 42467280\nTitle: Herbal and functional food phytochemicals in chronic disease: modulating oxidative stress and health outcomes.\nAbstract: Oxidative stress, described as an imbalance between the production of reactive oxygen species and antioxidant systems, has an important pathogenic role in many chronic diseases, such as cancer, cardiovascular disease, diabetes mellitus, stroke, and neurodegeneration. This narrative review investigates the effect of common herbal medicines and functional foods in oxidative stress, based on available experimental and clinical data. Curcuma longa, Emblica officinalis, Zingiber officinale, berries, and leafy vegetables, which contain bioactive molecules like polyphenols, flavonoids, and terpenoids, have been shown to have antioxidant and anti-inflammatory properties through activation of Nrf2 and NF-\u03baB signalling pathways. The important findings from this review suggest that curcumin and gingerol possess anticancer properties via the regulation of p53, MAPK, and ROS-JNK pathways, which induce apoptosis in cancer cells. Moreover, these bioactive compounds improve mitochondrial dysfunction and redox status in cardiovascular diseases. Bacosides and withanolides can be used for neuroprotection by preventing oxidative injury and protein aggregation in neurodegenerative diseases. The antioxidant-rich herbs and functional foods may have promising roles in oxidative stress-related disorders as preventative and supportive treatment options; however, further research is needed to establish their efficacy and safety in patients.\n\nID: 42440237\nTitle: Glymphatic dysfunction is associated with hyperglycemia-related cortical thinning in patients with type 2 diabetes mellitus.\nAbstract: Type 2 diabetes mellitus (T2DM) increases the risk of cognitive impairment through metabolic-neurodegenerative interactions, yet the underlying neural mechanisms remain unclear. This study investigates whether glycemic control modulates the relationships among glymphatic dysfunction, cortical thinning, and cognition in T2DM, with a focus on whether glymphatic impairment is associated with chronic hyperglycemia-related neurostructural decline. T2DM patients were stratified by glycemic control (Hemoglobin A1c\u2009<\u20097.5% vs. \u2265 7.5%). All participants underwent neuropsychological assessments and magnetic resonance imaging (MRI) to quantify cortical thickness, choroid plexus volume (CPV), perivascular space (PVS) volume, and the diffusion tensor image analysis along the perivascular space (DTI-ALPS) index. Group comparisons, Spearman correlations, and mediation analyses were used to examine the pathways linking glycemic control, glymphatic function, and cortical structure. A total of 54 poorly controlled T2DM patients, 38 well-controlled T2DM patients, and 99 healthy controls were included. Poorly controlled T2DM patients exhibited worse cognitive performance compared with healthy controls. Both T2DM groups showed reduced cortical thickness in the insula, fusiform gyrus, and supramarginal gyrus relative to healthy controls, with insular atrophy significantly associated with enlarged CPV. Markers of glymphatic dysfunction, including enlarged CPV, increased PVS volume, and reduced DTI-ALPS index, were most pronounced in the poorly controlled T2DM group. Cortical thickness and glymphatic measures each correlated with cognitive performance. Mediation analysis indicated that CPV showed associations consistent with a mediating role in the relationship between HbA1c and left insular cortical thinning. Compared with other subgroups, in the poorly controlled T2DM group, glymphatic changes were more pronounced, and the glymphatic-cognitive associations were more evident. Furthermore, CPV showed associations consistent with a mediating role in the relationship between hyperglycemia and cortical thinning in T2DM patients. These findings suggest that the glymphatic system may serve as an associative link between systemic metabolic dysregulation and structural neurodegeneration, offering potential imaging biomarkers for early neurological risk assessment in T2DM.\n\nID: 42435831\nTitle: Evaluation of the impact of gamma-aminobutyric acid on diabetic retinopathy in a large US population-based cohort.\nAbstract: To investigate how exposure to GABAergic medications affects diabetic retinopathy (DR) development, progression, and complications. Retrospective clinical cohort study using multi-institutional electronic health record data (TriNetX, US Collaborative Network) PARTICIPANTS: : Adults aged \u226518 years with type 2 diabetes mellitus with ophthalmology follow-up. Study cohorts had GABAergic prescription records for 6-months, 1-year, 3-years, or 5-years; control cohorts had no GABAergic prescriptions ever. Cohorts were propensity-score matched (PSM) on demographics, systemic comorbidities, common indications for GABAergic medications, and ophthalmic confounders. Outcomes included incident DR, progression from mild/moderate nonproliferative DR to severe nonproliferative DR, proliferative DR, or interventions required in advanced DR, and incident DR complications. Hazard ratio (HR) and 95% confidence intervals (CI); significance threshold <0.9 or >1.1. After successful PSM, there were 110,495 (6-months), 99,187 (1-year), 63,194 (3-years), and 40,810 (5-years) DR-naive study patients with the respective GABAergic prescription durations of interest. Compared to 109,603 DR-naive control patients, study patients demonstrated a significantly reduced HR for DR development at all time points from 6-months (HR 0.61, 95% CI 0.57-0.65) to 5-years (HR 0.81, 95% CI 0.77-0.85). Study patients (n=14,644) with baseline mild/moderate nonproliferative DR had a significantly reduced hazard of progressing to severe nonproliferative DR, proliferative DR, or DR interventions with 6-months (HR 0.75, 95% CI 0.68-0.82) and 1-year (HR 0.69, 95% CI 0.73, 0.86) GABAergic exposure. Prescription for 6-months (HR 0.74, 95% CI 0.68-0.80) to 3-years (HR 0.80, 95% CI 0.84-0.86) was associated with a significantly reduced hazard for DR complications. Stratification by 4 specific medication indications consistently showed a reduced hazard for DR development with a 6-month prescription duration. GABAergic medication use, particularly short-term exposure, is associated with a reduced hazard of DR development, progression, and complications. These exploratory findings support a potential role of GABAergic modulation in diabetic retinal disease.\n\nID: 42423809\nTitle: Polydatin inhibits hippocampal neurodegeneration in diabetic rats via modulation of oxidative stress and NF-kB/COX-2/IL-6 inflammatory pathway.\nAbstract: Impaired insulin function and persistent hyperglycemia damage the brain of diabetics and raise the risk of Alzheimer's disease (AD). Although polydatin (PLD) possesses promising biological effects, no major study has yet explored its anti-neurodegenerative efficacy in the hippocampus. This study therefore aims to investigate the probable protective effects of PLD against hippocampal neurodegeneration in diabetic rats, as well as explore its in-silico inhibitory activity against two key enzymes implicated in the progression of AD. Experimental diabetes was induced in male albino rats then PLD was administered orally to the diabetic rats (50\u00a0mg/kg b.wt.) daily for four weeks. In silico molecular docking was used to predict the interactions of PLD against BACE1 and AChE. PLD treatment significantly improved diabetic parameters, lowering blood glucose and raising serum insulin. Excitingly, PLD markedly alleviated oxidative stress by reducing lipid peroxidation and nitric oxide levels while enhancing antioxidant defenses (elevated GPx activity and GSH content) in the hippocampus of diabetic rats. PLD also suppressed neuroinflammation by down-regulating NF-\u03baB, COX-2, and IL-6 mRNA expression. Furthermore, PLD significantly elevated the protein level of IDE while lowered A\u03b21-42 level. In silico, PLD revealed potent binding affinity for BACE1 (-8.6 Kcal/mol) and AChE (-10.5 Kcal/mol), interacting with key residues, indicating its inhibition potential. Overall, PLD effectively reduced neurodegeneration in the hippocampus of diabetic rats via inhibiting oxidative stress, inflammation, and A\u03b21-42 accumulation. PLD may act as a promising multi-target anti-neurodegenerative candidate, capable of simultaneously modulating multiple pathways and more experimental validation are needed in the future.\n\nID: 42413647\nTitle: DAla2-GIP-Glu-PAL exerts neuroprotective effect on diabetic retinopathy by attenuating microglia activation and regulating NF-\u03baB/NLRP3 and Nrf2/HO-1 pathways.\nAbstract: DAla2-GIP-Glu-PAL, a kind of analogue of glucose-dependent insulinotropic polypeptide (GIP), has neuroprotective effects in the central nervous system. Currently, retinal neurodegeneration is regarded as an important feature of diabetic retinopathy (DR). The objective of this study was to investigate the neuroprotective effect of DAla2-GIP-Glu-PAL on diabetic retinopathy (DR), and its possible mechanisms, including regulation of microglia activation, inflammatory response, and oxidative stress. In this study, Type 2 diabetic db/db mice and wild-type (WT) mice were used. The morphology and structure of the retina and the ganglion cell layer were observed using histological methods. The levels of PSD95, IL-1\u03b2, IL-18, pNrf2, HO-1, MDA, SOD, NF-\u03baBp65, NLRP3, Cleaved-Caspase-1, and GSDMD were detected to evaluate retinal oxidative stress and neuroinflammation, and to observe the changes in levels of these indicators after the intravitreal injection of DAla2-GIP-Glu-PAL. The findings demonstrated that db/db mice exhibited significant retinal pathological changes, loss of ganglion cells, decreased synaptic transmission function, and excessive activation of microglia. In addition, the levels of NF-\u03baBp65, NLRP3, Cleaved-Caspase-1, GSDMD, L-1\u03b2, IL-18, and MDA increased, while the levels of pNrf2, HO-1, and SOD decreased. DAla2-GIP-Glu-PAL reversed the excessive activation of microglia and the expression of indicators related to inflammatory responses and oxidative stress, promoting the recovery of retinal neural structure and function.These results imply that DAla2-GIP-Glu-PAL exerted a neuroprotective effect on diabetic retinopathy in mice by inhibiting excessive activation of microglia, inflammatory response, and oxidative stress. Its underlying mechanisms may involve downregulating the NF-\u03baB/NLRP3 pathway and upregulating the Nrf2/HO-1 pathway.\n\nID: 42398881\nTitle: Mitochondrial Dysfunction and Diabetic Retinopathy: Research Progress from Pathogenic Mechanisms to Therapeutic Targets.\nAbstract: Diabetic retinopathy (DR) is one of the most common microvascular complications of diabetes mellitus (DM) and remains a major cause of visual impairment and blindness in adults. Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment.\n\nID: 42394935\nTitle: A convergence of global epidemics: diabetes as a modulator of neurodegenerative and neuro-inflammatory disorders.\nAbstract: Diabetes mellitus (DM) and neurological disorders are rapidly converging global health burdens, driven by population ageing, the growing prevalence of metabolic syndrome, and limited early detection and disease-modifying therapies for many neurological syndromes. Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface.\n\nID: 42390621\nTitle: Supra-additive neuroprotective effects of berberine-metformin combination in diabetic encephalopathy: Chou-Talalay synergy quantification, AMPK-Nrf2 axis modulation, and pharmacokinetic verification.\nAbstract: Type 2 diabetes mellitus (T2DM) increases the risk of hippocampal neurodegeneration and cognitive decline. Berberine and metformin independently activate AMPK and may engage Nrf2-mediated antioxidant defenses, yet their combined neuroprotective interaction has not been formally quantified using validated synergy frameworks, nor has its pharmacokinetic basis been verified. Streptozotocin-nicotinamide diabetic rats were allocated to twelve groups (n\u2009=\u200913/group) receiving berberine (50, 100, 150\u00a0mg/kg/day) or metformin (100, 200, 300\u00a0mg/kg/day) monotherapy, fixed-ratio 1:2 combinations, or vehicle controls (including a non-diabetic combination group) orally for six weeks. The novel object recognition (NOR) discrimination index served as the predefined primary endpoint for Chou-Talalay combination index (CI) analysis. Hippocampal mechanistic (n\u2009=\u20096/group) and satellite LC-MS/MS pharmacokinetic (n\u2009=\u20096/group) analyses were performed. Diabetes impaired NOR discrimination index (37.2\u2009\u00b1\u20093.8% vs. 68.4\u2009\u00b1\u20093.2%; p\u2009<\u20090.001). The reference combination (100\u2009+\u2009200\u00a0mg/kg) restored NOR to 67.1\u2009\u00b1\u20093.6% with CI\u2009=\u20090.65 (95% CI: 0.43-0.91), synergism maintained across the full effect range. All six neuroinflammatory endpoints achieved Benjamini-Hochberg-corrected significance (p_adj\u2009=\u20090.006-0.043; Tier 2). Non-diabetic combination animals showed reduced AMPK activation magnitude (1.53 vs. 2.31-fold; P_adj\u2009=\u20090.067; Tier 3, hypothesis-generating). LC-MS/MS verified bioequivalent drug exposure. Berberine-metformin co-treatment is associated with CI-quantified supra-additive recognition memory recovery in diabetic encephalopathy, with neuroinflammatory suppression as the most statistically robust mechanistic correlate. Pharmacokinetic findings are consistent with a pharmacodynamic rather than pharmacokinetic basis. Causal involvement of the AMPK-Nrf2 axis remains correlative pending direct loss-of-function validation.\n\nID: 42389857\nTitle: Adipokine dysregulation and oxidative stress in type 2 diabetes: Implications for neurodegeneration and neuroprotective eff ects of antidiabetic therapies.\nAbstract: Neurodegeneration is accelerated by Type 2 diabetes mellitus through adipokine dysregulation, insulin resistance, oxidative stress, and neuroinflammation. This could link metabolic imbalance to Alzheimer's disease, Parkinson's disease, and cognitive decline. The aim of this review is to clarify the roles of adipokines in type 2 diabetes-induced neurodegeneration, their molecular pathways, and the possible neuroprotective potential of antidiabetic agents. Literature was searched in PubMed, Google Scholar, and Scopus for Englishlanguage articles published up to November 2025, using keywords like adipokines, diabetes mellitus, neurodegeneration, neuroinfl ammation, and antidiabetics. Results highlight those elevated levels of pro-infl ammatory adipokines, such as TNF-\u03b1, IL-6, and resistin, together with reduced levels of neuroprotective adipokines, including adiponectin and leptin, may drive NF-kB activation, suppression of Nrf2 signaling, and amyloid and tau pathology. This is further exacerbated by oxidative stress and mitochondrial dysfunction. Antidiabetic agents like metformin, GLP-1 agonists, thiazolidinediones, and SGLT2 inhibitors restore adipokine balance, enhance AMPK/PPAR\u03b3 signaling, and show cognitive benefits in mild cognitive impairment cohorts per clinical trials. In conclusion, repurposing antidiabetics via biomarker-guided multiple therapies offers disease-modifying promise for type 2 diabetes-linked neurodegeneration, necessitating large randomized controlled trials in prediabetic populations.

The diffusion tensor imaging along the perivascular space (DTI-ALPS) index has been proposed as a non-invasive imaging surrogate that may reflect aspects of glymphatic system activity.ObjectiveWe investigated the relationship between ALPS index, cognition, brain structure, and plasma Alzheimer's disease biomarkers in T2DM patients.MethodsTwo independent cohorts were analyzed: Cohort 1 included 60 age, sex, and education matched participants (20 T2DM with MCI, 20 T2DM with normal cognition, and 20 healthy controls); Cohort 2 comprised 35 elderly T2DM patients assessed for plasma AD biomarkers. All participants underwent MRI for ALPS index calculation and structural imaging. Cognition was evaluated using the Mini-Mental State Examination and Montreal Cognitive Assessment.ResultsThe ALPS index was significantly lower in T2DM patients with MCI compared to cognitively normal T2DM patients and healthy controls, and showed discriminative ability for MCI. Lower ALPS index correlated with poorer cognitive scores and was associated with brain atrophy. Mediation analysis indicated that the volume of the right opercular inferior frontal gyrus mediated the relationship between ALPS index and cognition scores. Furthermore, the ALPS index negatively correlated with plasma pTau217 adjusted by age and sex in T2DM patients.ConclusionsA lower ALPS index is associated with cognitive impairment, brain atrophy, and plasma tauopathy, which may serve as a promising non-invasive imaging biomarker for early identification of neurodegeneration risk in T2DM patients.\n\nID: 42364841\nTitle: Chrononutrition as a modulator of retinal metabolic resilience: A translational framework linking circadian biology to ocular disease.\nAbstract: Chrononutrition-the alignment of feeding-fasting cycles with endogenous circadian rhythms-has emerged as a key determinant of systemic metabolic homeostasis. However, its relevance in ocular biology and retinal disease remains insufficiently defined within a translational framework. The retina, characterized by high energetic demand, intrinsic circadian oscillators, and tight coupling between mitochondrial function and redox balance, represents a uniquely vulnerable target to chrono-metabolic disruption. Here, we propose a mechanistically integrated model in which feeding timing acts as a systemic regulator of retinal metabolic resilience. We synthesize evidence demonstrating that circadian misalignment and irregular nutrient intake disrupt retinal bioenergetics, impair insulin signaling, and promote mitochondrial dysfunction and oxidative stress-hallmarks of major retinal diseases including diabetic retinopathy, age-related macular degeneration, and glaucomatous neurodegeneration. Particular emphasis is placed on nutrient-sensitive pathways, including peroxisome proliferator-activated receptors (PPARs), the AMPK/SIRT1 axis, and melatonin-mediated chronoregulation, as key interfaces linking metabolic cues with retinal circadian control. Importantly, we advance the concept that chrononutrition extends beyond dietary composition to function as a temporal modulator of disease-relevant pathways. Based on convergent experimental evidence, we outline a translational framework in which rhythm-aligned feeding patterns and time-dependent nutritional interventions may enhance mitochondrial efficiency, stabilize redox homeostasis, and improve retinal stress adaptation. Although direct clinical evidence remains limited, this paradigm provides a biologically grounded basis for the development of chrono-nutritional strategies as adjunctive approaches in retinal disease prevention and management.\n\nID: 42353267\nTitle: Neuroprotection in Early Diabetic Retinal Disease Using Eyedrop Delivery.\nAbstract: Diabetic retinal disease (DRD) has classically been defined as a microvascular complication of diabetes; however, the recent evidence highlighted the key role of neuronal degeneration during the earliest stages of its pathogenesis. Therefore, neuroprotection has emerged as a promising therapeutic strategy to prevent disease progression. Topical administration via eyedrops represents a non-invasive approach to deliver neuroprotective agents directly to the retina. This review summarizes the current advances in the field of neuroprotective therapies against early DRD with a special focus on topical delivery, including preclinical and clinical evidence, while discussing the relevance of the transscleral route of absorption in all of them. In this review, the most promising neuroprotective compounds under development will be discussed, highlighting the opportunity that they represent for treating early stages of DRD.\n\nID: 42353026\nTitle: The AGE-RAGE-DIAPH1 Axis in Type 2 Diabetes and Metabolic Dysfunction: From Carbonyl Stress to Diabetic Myocardial and Neuronal Injury.\nAbstract: Carbonyl stress, chronic inflammation, and progressive tissue injury accompany type 2 diabetes mellitus (T2DM) and obesity. Yet, the molecular systems that connect these processes with cardiac, vascular and neuronal complications are incompletely defined. This review examines the AGE-RAGE-DIAPH1 axis as a mechanistic link between metabolic dysfunction and diabetic myocardial and neuronal injury, with emphasis on vascular and myocardial remodeling and emerging implications for autonomic neuronal vulnerability. We summarize current evidence on the formation and accumulation of advanced glycation end-products and other RAGE ligands in metabolic disease, DIAPH1's structural and signaling role as an intracellular effector of RAGE, and the cellular consequences of pathway activation in vascular, neural, and cardiac tissues. Across experimental models, this signaling axis promotes oxidative stress and inflammatory activation, leading to endothelial dysfunction and barrier failure. Subsequent fibrotic remodeling provides a biologically plausible route through which metabolic stress may be translated into persistent organ injury. In the heart, these mechanisms are linked to coronary microvascular dysfunction, altered cardiomyocyte phenotype, calcium handling abnormalities, and myocardial fibrosis. In the autonomic nervous system, limited but emerging data connect RAGE activation to oxidative injury and mitochondrial dysfunction, abnormal neuronal excitability, and structural vulnerability. Direct evidence linking DIAPH1 to autonomic neurons is lacking. We also review biomarker candidates related to this pathway, including circulating AGEs and soluble RAGE isoforms, skin AGE measurements, imaging markers of myocardial remodeling, and autonomic functional measures. Finally, we discuss pharmacological and natural compounds that target AGE formation, ligand accumulation, RAGE signaling, or intracellular protein interactions linked to this axis. Overall, the available evidence supports the AGE-RAGE-DIAPH1 axis as a credible mechanistic concept and a potentially informative translational hypothesis in T2DM. However, the AGE-RAGE component is supported more strongly than DIAPH1-specific involvement in human diabetic myocardial disorder or cardiovascular autonomic neuropathy. The value of DIAPH1 as a biomarker or therapeutic target in these neurocardiac complications remains to be established.\n\nID: 42342866\nTitle: Bioenergetic failure in diabetic peripheral neuropathy: from glucotoxicity to multidimensional metabolic imbalance.\nAbstract: Diabetic peripheral neuropathy (DPN), particularly distal symmetric polyneuropathy, characterized by length\u2011dependent axonal damage, is a common chronic complication of type 2 diabetes mellitus. The pathogenesis of DPN is complicated, yet one thing is clear: long axons require a great deal of energy. When axonal transport is compromised by impaired energy metabolism, neuronal somata fall into an energy deficit that triggers neurodegeneration. While earlier work centered on hyperglycemia-induced cytotoxicity, recent studies have increasingly implicated dysregulation of glucose, lipid, and amino acid metabolism as key contributors to DPN. In this review, we integrate the anatomical organization of peripheral nerves, bioenergetic pathways, and axon-Schwann cell interactions to establish a framework for understanding how glucose, lipid, and amino acid dysregulation converge to induce bioenergetic failure in DPN. Based on these mechanisms, we further discuss novel strategies aimed at restoring metabolic homeostasis in neurons and Schwann cells. Importantly, correcting a single metabolic pathway is unlikely to halt or reverse DPN. Instead, restoring global energy homeostasis to rebalance axonal energy supply and demand may be essential for preserving peripheral nerve function.\n\nID: 42339074\nTitle: Redox regulation of PDE6 and cGMP signaling in diabetic retinal neurodegeneration.\nAbstract: Diabetic retinal neurodegeneration is increasingly recognized as an early and critical component of diabetic retinopathy, driven in part by persistent oxidative stress and dysregulated intracellular signaling. Among these pathways, cyclic guanosine monophosphate (cGMP) signaling plays a central role in photoreceptor function and survival. Phosphodiesterase 6 (PDE6), the key enzyme responsible for cGMP hydrolysis in photoreceptors, has been extensively studied in inherited retinal disorders; however, its regulation under diabetic and redox-imbalanced conditions remains insufficiently defined. In this review, we examine the emerging role of redox imbalance in modulating PDE6 activity and stability in the diabetic retina. We discuss how mitochondrial and non-mitochondrial sources of reactive oxygen species (ROS) may disrupt PDE6 through proteostasis-related mechanisms involving AIPL1-dependent maturation and FAT10-mediated degradation. These alterations may lead to cGMP dysregulation, impaired ion channel activity, calcium imbalance, and photoreceptor dysfunction. We propose that PDE6-cGMP signaling represents a redox-sensitive hub linking oxidative stress to early neuronal damage in diabetic retinopathy. This mechanistic framework highlights PDE6 as a potential molecular target and supports the development of redox-based strategies aimed at preserving retinal function and preventing neurodegeneration.\n\nID: 42334690\nTitle: Berberine attenuates hyperglycemia induced neurodegeneration in mice by modulation of Nrf2 expression.\nAbstract: Cognitive impairment is one of the complication associated with type 2 diabetes mellitus (T2DM), and patients with T2DM are more likely to develop memory-related neurodegenerative disorders. Berberine (BBR), a natural compound used in the treatment of diabetes and diabetes-associated cognitive dysfunction (DACD), although the underlying mode of action remains largely unknown. Herein, we investigated whether nuclear factor erythroid 2-related factor 2 (Nrf2), a redox-associated factor, is essential to the neuroprotective action of BBR. Streptozotocin (STZ; 100\u00a0mg/kg IP, single shot) was used for induction of T2DM in mice. BBR was administered before STZ administration in Pre-treatment group and after STZ administration in Post-treatment group for 4 weeks. Learning and memory was assessed using Y-maze test and Step through passive avoidance task. The impact of BBR on tight junction proteins, VEGF, GLUT receptors and Nrf2/HO-1 signaling in the hippocampus was analyzed using qPCR. Using standard biochemical tests, the activity of AChE and ChAT were assessed in the hippocampus of T2DM mice. Our findings indicate that BBR significantly improved cognition in T2DM mice. It significantly increased the gene expression of tight junction proteins and VEGF in the hippocampus of T2DM mice. Also, BBR improved glucose uptake by upregulating GLUT receptors. Furthermore, a marked elevation of AChE activity and decreased activity of ChAT was seen in STZ treated mice which upon treatment with BBR was reversed. Moreover, the expression of Nrf2 and its downstream genes was reduced in the diabetic group and was significantly reversed upon BBR treatment. Taken together, our results demonstrate that BBR may exerts protective effects against cognitive decline, by decreased BBB permeability, enhanced glucose uptake, enhanced neurogenesis and activation of Nrf2/HO-1 signaling in the hippocampus of T2DM mice. Our study may signify a new mode of action and a novel therapeutic target for DACD.\n\nID: 42321543\nTitle: Dopaminergic nigrostriatal vulnerability in Parkinson's Disease with diabetes: evidence from severity-matched cohorts.\nAbstract: Diabetes Mellitus (DM) has been recognized as a potential risk factor and disease-modifier in Parkinson's Disease (PD), being associated with worse motor and cognitive outcomes, and altered susceptibility of neural pathways. This study investigated the impact of DM on nigrostriatal dopaminergic vulnerability independently of disease severity in drug-na\u00efve PD patients. This study analyzed two independent cohorts of PD patients (multi-center PPMI n\u2009=\u2009174, single-center UniBS n\u2009=\u200995). Patients with and without DM were first compared and then matched for age, sex, and clinical severity. All patients underwent baseline 123I-FP-CIT imaging to quantify dopamine transporter binding. Dopaminergic binding, neural reserve index and molecular connectivity patterns were compared between severity-matched groups. Patients with DM were older, predominantly male, and exhibited worse non-motor and cognitive symptoms. After severity matching, PD-DM exhibited more preserved nigrostriatal dopamine uptake compared to PD-n. PD-DM also showed fewer nigrostriatal dopaminergic connectivity alterations (10% vs. 21%) and reduced neural reserve index in the left putamen and - only in the single-center cohort- whole striatum. In drug-na\u00efve PD patients, comorbid diabetes is associated with comparable clinical severity despite milder dopaminergic loss. This suggests an increased dopamine system vulnerability linked to DM, reducing the efficiency and compensatory mechanisms of nigrostriatal dopaminergic networks in PD.\n\nID: 42320189\nTitle: Minocycline as a therapeutic candidate in diabetic retinopathy: insights into pathophysiology and translational potential.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss worldwide and is increasingly recognized as a complex neurovascular disease characterized by early neuroinflammation, neurodegeneration, and microvascular dysfunction. Current therapies primarily target late-stage vascular complications and do not adequately address the upstream mechanisms involved in DR onset and progression. Minocycline, a second-generation semisynthetic tetracycline with high lipophilicity, has emerged as a promising therapeutic candidate because of its pleiotropic pharmacological effects beyond antimicrobial activity. Accumulating experimental evidence indicates that minocycline exerts anti-inflammatory, anti-apoptotic, mitochondrial-protective, and potentially epigenetic regulatory effects in diabetic retinal tissues and cellular models. Mechanistically, minocycline suppresses microglial activation, attenuates pro-inflammatory signaling, stabilizes the blood-retinal barrier, preserves mitochondrial function, inhibits matrix metalloproteinase activity, and has been associated with changes in histone acetylation and methylation under diabetic conditions. These actions may help preserve retinal neurovascular integrity and reduce neuronal and microvascular injury in experimental DR models. Despite promising preclinical findings, clinical evidence remains limited. Early-phase clinical studies indicate that oral minocycline is generally well tolerated; however, its efficacy has not been established in adequately powered clinical trials. This review summarizes the pharmacological properties of minocycline, critically examines its molecular mechanisms in DR pathogenesis, and discusses current clinical evidence, translational challenges, and future research directions. Although available data support further investigation of minocycline for DR, additional preclinical and clinical studies are needed to determine its therapeutic efficacy and clinical applicability.\n\nID: 42316561\nTitle: Role of Cholesterol Metabolism in the Link Between Diabetes and Alzheimer's Disease.\nAbstract: Type 2 Diabetes Mellitus (T2DM) and Alzheimer's Disease (AD) share complex metabolic disturbances, with cholesterol dysregulation emerging as a central mechanistic link. Although brain cholesterol metabolism operates largely independently of peripheral lipid pools, it is highly susceptible to disruption, particularly in the insulin-resistant ApoE4 genotype. This review follows a structured literature approach using PubMed, Scopus, and Web of Science (2000-2025) to critically evaluate mechanistic and translational evidence on cholesterol- T2DM-AD interplay. It critically evaluates current evidence on cholesterol production, transport, and elimination in the Central Nervous System (CNS), focusing on the roles of astrocytes, neurons, and transporters such as ATP-binding cassette transporter A1 (ABCA1). It also explores how peripheral metabolic stress in T2DM affects central cholesterol homeostasis and contributes to amyloid- beta (A\u03b2) accumulation and neurodegeneration. Pharmacological approaches targeting cholesterol regulation, including statins, liver X receptor (LXR) modulators, and glucagon-like peptide-1 (GLP-1) receptor agonists, are discussed. Findings indicate that impaired cholesterol regulation disrupts neuron-astrocyte interactions, enhances A\u03b2 deposition, and accelerates neurodegeneration. Controversies remain regarding the relative impact of peripheral vs. central cholesterol imbalance and Blood-Brain Barrier (BBB) permeability in therapy. In T2DM, peripheral insulin resistance and hypercholesterolemia exacerbate central cholesterol imbalance, thereby intensifying AD pathology. Emerging therapeutic studies suggest that modulation of cholesterol pathways may reduce neuroinflammation, promote A\u03b2 clearance, and slow cognitive decline. The overlap between T2DM and AD highlights cholesterol metabolism as a pivotal pathogenic axis. While peripheral factors worsen central dysregulation, CNS-specific disturbances independently drive disease progression. Targeted modulation of cholesterol pathways, through statins, LXR modulators, and GLP-1 agonists, shows promise but demands precision approaches tailored to genotype and BBB permeability. The cholesterol-AD-T2DM axis represents a promising therapeutic target. Addressing cholesterol dysregulation could enable novel, personalized strategies to mitigate neurodegeneration and cognitive decline.\n\nID: 42312374\nTitle: Metabolic context modulates neuroinflammation: Type 2 diabetes mellitus moderates the association of interleukin-8 with amyloid pathology and cognitive decline in mild cognitive impairment.\nAbstract: BackgroundInterleukin-8 (IL-8) exhibits dual roles in Alzheimer's disease (AD), yet how the metabolic milieu of type 2 diabetes mellitus (T2DM) influences its impact in mild cognitive impairment (MCI) remains unclear.ObjectiveThis study aimed to investigate how T2DM status moderates the longitudinal association between baseline plasma IL-8 levels and AD-related outcomes, including cognitive decline, amyloid-\u03b2 (A\u03b2) deposition, and neurodegeneration.MethodsData from 373 MCI participants (Alzheimer's Disease Neuroimaging Initiative cohort) were analyzed. Moderation analyses examined the IL-8\u2009\u00d7\u2009T2DM interaction on cognitive trajectories, amyloid-\u03b2 (A\u03b2) accumulation, and regional atrophy, adjusting for key covariates.ResultsIn the T2DM group, higher baseline IL-8 was significantly associated with a slower longitudinal increase in Clinical Dementia Rating-Sum of Boxes (p\u2009=\u20090.005), indicating preserved clinical function. Furthermore, elevated IL-8 in the T2DM cohort correlated with lower hippocampal A\u03b2 burden (p\u2009=\u20090.041) and attenuated atrophy rates in the parahippocampal cortex (p\u2009=\u20090.044). In contrast, no significant associations between IL-8 and any AD biomarkers or cognitive trajectories were observed in the non-T2DM group.ConclusionsThis research demonstrates that the role of IL-8 in MCI is \"context-dependent,\" contingent upon the patient's metabolic state. The author suggests that under chronic metabolic stress, IL-8 may reflect an adaptive immune response that mitigates amyloid pathology and slows neurodegeneration. These results emphasize the necessity of integrating metabolic profiles into the interpretation of neuroinflammatory biomarkers to facilitate personalized therapeutic strategies for AD.\n\nID: 42304926\nTitle: Linking Neurodegeneration and Age-related Macular Degeneration: Unified Pathways and Intervention Strategies.\nAbstract: Age-related macular degeneration (AMD) is caused by the degeneration of photoreceptors and retinal pigment epithelium (RPE) along with drusen deposition and is the leading cause of vision loss in older adults. Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.\n\nID: 42289507\nTitle: The effect of canagliflozin on hippocampal dendrite morphology in a model of Alzheimer's disease induced by intracerebroventricular injection of streptozotocin.\nAbstract: Alzheimer's disease (AD) and diabetes mellitus (DM) share common pathophysiological features. However, the effects of antidiabetic drugs on neurodegeneration are not completely known. Canagliflozin, a novel option for DM treatment, is a dual inhibitor of sodium glucose co-transporter type 2 (SGLT2) and acetylcholinesterase. The aim of this study is to examine the morphological features of dendrites and dendritic spines of pyramidal neurons in hippocampus of AD model treated with canagliflozin. The model of AD was obtained by intracerebroventricular injection of streptozotocin. Then, the rats were divided into 3 groups: vehicle, donepezil, and canagliflozin. The injections were i.c.v. administered for 7 days. Behavioral tests were performed to evaluate memory, anxiety, and motor functions. Brain tissues were processed by Golgi impregnation method. Pyramidal neurons in the CA1 region were examined using Neurolucida software. Dendritic branching, total dendrite length, dendritic spine density, and dendritic spine types were analyzed. Compared to the vehicle group, the donepezil group and the canagliflozin group exhibited significantly higher dendritic branches (p\u2009=\u20090.0273, p\u2009=\u20090.0195) and total dendrite length (p\u2009=\u20090.0171, p\u2009=\u20090.0360), respectively. The total dendritic spine density (p\u2009<\u20090.0001) and the mushroom-type dendritic spine density (p\u2009=\u20090.0001) were significantly low in the donepezil group compared to the vehicle group. However, canagliflozin did not induce any significant alterations in the dendritic spine density. Canagliflozin treatment was as effective as donepezil treatment on hippocampal dendrite morphology. This morphological framework, indicating dendritic plasticity and remodeling, serve to better understand the cellular effects of canagliflozin. Therefore, our study may contribute to the development of novel strategies for therapy of AD.\n\nID: 42286886\nTitle: The positive correlation between the progressive photoreceptor damage and the increased macular leakage indicating the severity of diabetic retinopathy.\nAbstract: To evaluate photoreceptor changes and their correlation with microvascular alterations in different stages of diabetic retinopathy (DR). Thirty-two treatment-na\u00efve DR patients (50 eyes) without clinically significant macular edema were graded into mild, moderate, and severe non-proliferative DR (NPDR) and proliferative DR (PDR). The macula was imaged using adaptive optics scanning laser ophthalmoscopy (AO-SLO) at five subsections. Mean/minimum photoreceptor density, cell regularity, dispersion, spacing, and dark areas were recorded. Central macular thickness (CMT) and macular leakage index (MLI) were measured. The percentage of dark areas increased gradually with DR severity: 1.86\u2009\u00b1\u20091.52 (mild NPDR), 3.32\u2009\u00b1\u20091.45 (moderate NPDR), 4.22\u2009\u00b1\u20092.11 (severe NPDR), and 5.92\u2009\u00b1\u20093.06 (PDR) (P\u2009=\u20090.007). MLI also progressively increased (P\u2009=\u20090.01): 0.31\u2009\u00b1\u20090.60%, 3.47\u2009\u00b1\u20094.70%, 6.92\u2009\u00b1\u20095.44%, and 8.98\u2009\u00b1\u20093.58%, respectively. MLI showed a positive correlation with the percentage of dark areas (r\u2009=\u20090.36, P\u2009=\u20090.01). No significant changes were observed in photoreceptor density, regularity, dispersion, spacing, CMT, or visual acuity. Dark areas observed by AO-SLO suggest photoreceptor abnormalities, indicating decreased waveguiding ability and localized dysfunction as DR progresses. The positive correlation between dark areas and macular vascular leakage implies early dysfunction of the retinal neurovascular unit (NVU) in DR, warranting further investigation.\n\nID: 42285402\nTitle: Epigenetic encoding of metabolic memory in diabetic retinopathy: From molecular imprinting to neurovascular network reprogramming.\nAbstract: Diabetic retinopathy (DR) is increasingly recognized not merely as a microvascular complication, but as a chronic neurodegenerative disorder of the central nervous system characterized by progressive neurovascular unit (NVU) dysregulation. In many individuals, DR continues to progress despite subsequent glycaemic normalization, a phenomenon known as metabolic memory. Emerging evidence indicates that transient hyperglycaemic stress is converted into durable transcriptional programs through epigenetic encoding mechanisms. In this Review, we propose a hierarchical framework in which early metabolic insults are written into chromatin via DNA methylation, histone modifications, and noncoding RNA networks. Crucially, these epigenetic storage systems do not act in isolation; they systematically disrupt the intricate intercellular crosstalk within the NVU. Epigenetic locking of microglia into pro-inflammatory phenotypes, coupled with M\u00fcller cell gliosis and the suppression of neural plasticity, drives sustained pathological shifts that transform localized cellular stress into a tissue-wide network collapse. Furthermore, we critically evaluate the potential of extracellular vesicle-mediated communication in amplifying this memory across the NVU. By targeting the fundamental epigenetic drivers of glial reactivity and neurodegeneration across the integrated NVU, this Review highlights innovative strategies, such as programmable epigenetic editing (CRISPR/dCas9), to reset homeostasis and offers a transformative paradigm for early intervention in DR.\n\nID: 42282664\nTitle: Inhibition of Soluble Epoxide Hydrolase Rescues Cognitive Deficits by Preserving Neurovascular Integrity and Attenuating Glial- and Neuropathology in Diabetic-Related Dementia.\nAbstract: Diabetes mellitus (DM) is a major risk factor contributing to the development of Alzheimer's disease-related dementias (ADRD). While one of the early symptoms of both Alzheimer's disease (AD) and DM-related ADRD is a reduction in cerebral blood flow, the underlying biological mechanisms driving this decline remain to be fully elucidated. Genome-wide association studies have linked AD/ADRD to single-nucleotide polymorphisms in the gene encoding soluble epoxide hydrolase (sEH), an enzyme we previously reported to be upregulated in the brains of an AD rat model. Our previous work also demonstrated that chronic inhibition of sEH with 1-trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl) urea (TPPU) preserves hippocampal-dependent spatial learning and memory and improves cerebral hemodynamics in both AD and DM-ADRD models. In the present study, we found that chronic TPPU treatment (1 mg/kg/day for 9 weeks) reduced brain sEH expression, improved cortical-based long-term non-spatial recognition memory involving both cortical and hippocampal networks, and reduced anxiety in DM-ADRD rats. TPPU improved brain perfusion and normalized impaired whisker-evoked functional hyperemia, an effect linked to upregulation of Kir2.1 expression in cerebral capillaries. Furthermore, TPPU restored tight junction proteins (ZO-1 and OCLN), mitigated capillary rarefaction, and suppressed astrocyte and microglial activation. At the cellular level, TPPU attenuated hippocampal neurodegeneration, restored the expression of synaptic proteins (PSD95 and SY38), and reduced levels of key pro-inflammatory chemokines, including MCP-1, RANTES, and MIP-1\u03b1, in DM-ADRD. In conclusion, TPPU preserves cognitive function in DM-ADRD by mitigating cerebrovascular dysfunction, neuroinflammation, and gliosis while protecting synaptic integrity and neuronal survival, representing a promising therapeutic strategy for DM-ADRD.\n\nID: 42281177\nTitle: Geroprotective Agents, Including Glucagon-Like Peptide-1 Receptor Agonists, for Ocular Health.\nAbstract: Aging has long been implicated in the onset and progression of major retinal diseases, including age-related macular degeneration (AMD), diabetic retinopathy (DR), and retinal vein occlusion (RVO). Glaucoma is likewise increasingly recognized as an age-related disorder. Across these conditions, converging patterns of neurodegeneration and microvascular injury contribute to age-associated ocular decline. Structural and neuronal degeneration of the retina, including loss of retinal ganglion cell axons, along with impaired microvascular circulation and chronic inflammation, contribute to the pathogenesis of glaucoma, AMD, DR, and RVO. Geroprotectors, a class of longevity-promoting pharmacologic agents investigated for systemic benefits in cardiovascular and neurological aging, have therefore drawn growing ophthalmic interest for their potential relevance to ocular health and the management of age-associated eye diseases. These agents are now frequently encountered as concomitant medications in ophthalmic practice, yet their ocular effects remain incompletely characterized, variably reported, and in some cases controversial. Glucagon-like peptide-1 (GLP-1) receptor agonists, widely used for glycemic control and increasingly for weight management, have been associated with reduced risk of age-related glaucoma but also with unconfirmed reports of severe nonarteritic anterior ischemic optic neuropathy. Similar uncertainties surround other geroprotective, metabolic, and weight-modifying therapies, creating challenges for clinicians attempting to incorporate evolving pharmacologic evidence without compromising patient safety. This review synthesizes reported therapeutic and adverse ocular outcomes across geroprotective agents to support clinical awareness, identify knowledge gaps, and guide future investigation. The agents reviewed include GLP-1 receptor agonists, metformin, sodium-glucose cotransporter-2 inhibitors, statins, cannabinoids, calcium channel blockers, spermidine, taurine, nicotinamide adenine dinucleotide precursors, rapamycin, and mifepristone.\n\nID: 42280391\nTitle: Maternal palmitoleic acid supplementation attenuates neurodegenerative programming in aged offspring exposed to gestational diabetes.\nAbstract: Background/Objectives: Maternal hyperglycemia is associated with adverse neurodevelopmental outcomes in offspring; however, its long-term effects on brain aging remain unclear. This study investigated whether maternal hyperglycemia induces persistent molecular and behavioral alterations in aged male offspring and whether maternal palmitoleic acid supplementation exerts protective effects. Methods: The pregnant rats were divided into four groups: PCM, PDM, PDM/CPA, and PDM/TPA. Male offspring were analyzed at 48 weeks of age. Results: Maternal hyperglycemia significantly increased cerebral RAGE expression (~1.6-fold) and tau phosphorylation (~1.8-fold), accompanied by reduced Akt phosphorylation, impaired Nrf2-related antioxidant responses, and increased inflammatory gene expression. These molecular alterations are associated with impaired recognition memory, as reflected by a marked reduction in the discrimination index in the novel object recognition test. Maternal CPA/TPA supplementation partially attenuated these abnormalities. Conclusions: These findings suggest that maternal hyperglycemia may induce long-lasting molecular alterations associated with neuroinflammation, impaired insulin-related signaling, and cognitive dysfunction in aged offspring. Maternal palmitoleic acid supplementation may partially mitigate the adverse developmental alterations associated with intrauterine hyperglycemic exposure.\n\nID: 42269219\nTitle: Alogliptin attenuates diabetes-associated cognitive impairment in rats via HMGB1/RAGE/TLR4-NF\u03baB pathway modulation.\nAbstract: Chronic hyperglycemia associated with diabetes mellitus (DM) induces systemic metabolic disturbances that progressively promote microvascular and macrovascular complications including the impairment of neuronal integrity and cognitive function. Accumulating evidence has supported that cognitive impairment and Type 2 Diabetes Mellitus (T2DM) share common pathological mechanisms. The current investigation explored potential benefits of alogliptin, a dipeptidyl peptidase IV (DPP-4) inhibitor, on diabetes induced cognitive impairment by revealing its role in attenuating neuroinflammatory pathways. T2DM was induced with a high-fat diet (HFD) for 8 weeks followed by a single low dose of streptozotocin (STZ, 30\u202fmg/kg I.P). Rats of the treatment groups received alogliptin at different doses (20\u202fmg/kg/day or 40\u202fmg/kg/day) for 28 days. Memory function was assessed using the Morris Water Maze (MWM) and Y-maze tests. Blood samples were withdrawn at the end of the experiment, and brain tissue was dissected for biochemical, immunohistochemical, and histopathological examination. Alogliptin reduced diabetes-induced cognitive impairment evident in memory tasks, alleviated histological changes in the brain and attenuated oxidative stress by increasing SOD, CAT and GSH levels while reducing MDA levels. Alogliptin also decreased neuroinflammatory signaling via reducing HMGB1, RAGE, TLR4/ NF-\u03baB which in turn decreased inflammatory cytokines TNF-\u03b1 and IL-1\u03b2. Alogliptin also refined mTOR signaling pathway and improved neuronal health. According to these findings, alogliptin reduces neuroinflammation and alters mTOR action leading to the improvement of neurodegeneration and memory function.\n\nID: 42263370\nTitle: Sensory abnormalities and entrapment neuropathies identified by nerve conduction studies in patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder primarily affecting motor neurons; however, non-motor symptoms, including sensory and autonomic disturbances, are increasingly recognized. This retrospective cross-sectional study evaluated the frequency of sensory and entrapment neuropathies in 114 patients with ALS using electrodiagnostic (EDX) studies. Demographic characteristics, comorbidities, and sensory and autonomic symptoms were documented. Electrophysiological evidence of sensory neuropathy was identified in 20 patients overall (20/114, 17.5%), including 10 patients without diabetes mellitus (DM), whereas entrapment neuropathy was detected in 28 patients overall (28/114, 24.6%), including 16 of those without DM or hypothyroidism. Sensory neuropathy was significantly associated with both DM and a history of chronic disease. In contrast, these comorbid conditions were not significantly associated with entrapment neuropathy. Furthermore, patient-reported symptoms showed no correlation with electrophysiological evidence of sensory involvement on EDX. Sensory neuropathy was more frequent in patients with spinal-onset than bulbar-onset disease, although the difference was not statistically significant. This study confirms that sensory involvement is not uncommon in ALS. Although clinical symptoms are poor predictors, electrophysiological abnormalities consistent with sensory and entrapment neuropathies are common. A significant proportion of these abnormalities are idiopathic and may directly reflect the disease process itself, particularly in spinal-onset cases.\n\nID: 42256312\nTitle: Neuroprotective effects of Platycladus orientalis ethyl acetate fraction on retinal M\u00fcller cells: modulation of AKT1/mTOR and Raf-1/MEK1/2 pathways via AMPK activation.\nAbstract: P. orientalis has previously demonstrated protective effects against diabetic microvascular complications but its specific role in mitigating neurodegenerative events in diabetic retinopathy remains unknown. This study investigates the neuroprotective effects of Platycladus orientalis ethyl acetate fraction (EAPO) on retinal M\u00fcller cells (rMc-1) under different glucose stress. Bioactive compounds in the EAPO were identified using liquid chromatography-mass spectrometry, while its cytotoxicity was assessed in vitro. The expression of gene and protein biomarkers related to neuronal survival like mammalian target of rapamycin (mTOR), mitogen-activated extracellular signal-regulated kinase 1/2 (MEK1/2), rapid accelerated fibrosarcoma-1 (Raf-1), serine/threonine kinase 1 (AKT1), vascular endothelial growth factor (VEGF), and VEGF receptor 2 (VEGFR2) in EAPO- treated rMc-1 were compared with control group under different glucose concentrations. Phytochemical analysis of EAPO revealed the presence of diterpenoids, monoterpene esters, phenolic glycosides, and saturated fatty acids. EAPO demonstrated low cytotoxicity (IC50 = 0.32 mg/mL) in rMc-1 under high-glucose stress conditions. Mechanistic study showed that EAPO treatment significantly mitigated glucose-induced cytotoxicity and neurodegeneration by downregulating the expression of VEGF, VEGFR2, mTOR, Raf-1, and MEK1/2, while enhancing phosphorylation of AKT1. Co-treatment with AICAR, an activator of AMP- activated protein kinase (AMPK), further amplified the neuroprotective effects of EAPO. In contrast, inhibition of AMPK using compound C exacerbated glucose-induced cytotoxicity and neurodegenerative signaling. The combination of EAPO and AICAR synergistically inhibited VEGF/VEGFR2 signaling and its downstream pathways (mTOR and Raf- 1/MEK1/2) while promoting AKT1-mediated neuronal survival. This study provides new mechanistic insight into the neuroprotective effects of P. orientalis on rMc-1 under diabetic stress. EAPO could attenuate high-glucose-induced neuronal toxicity in rMc-1 by modulating the AKT1/mTOR and Raf-1/MEK1/2 pathways through AMPK activation.\n\nID: 42255937\nTitle: Synaptic alterations are preceding the axonal loss in optic atrophy of Wolfram syndrome mouse model.\nAbstract: Wolfram syndrome is a rare autosomal recessive disorder characterized by antibody-negative early-onset diabetes mellitus, optic atrophy, sensorineural hearing loss, arginine-vasopressin deficiency, and progressive neurodegeneration of the brainstem and cerebellum. It is caused primarily by pathogenic variants in the WFS1 gene, which encodes a transmembrane endoplasmic reticulum-resident protein involved in the unfolded protein response and cellular calcium homeostasis. Although multiple rodent models of Wolfram syndrome have been developed and shown to exhibit visual defects, some studies have reported significant vision loss prior to any detectable axonal degeneration or myelin abnormalities, and the mechanisms underlying these early visual deficits remain poorly understood. Recent in vitro studies have demonstrated altered synaptic contacts and aberrant neurite morphology in WFS1-deficient cerebral organoids and human iPSC-derived neurons, respectively. These findings prompted us to investigate, for the first time in vivo, whether synaptic and dendritic abnormalities occur in the retina of Wfs1 knockout mice. Using confocal microscopy, we examined retinal and optic nerve histology in Wfs1 knockout mice at 4 and 7 months of age. Our analysis reveals progressive synaptic alterations in the inner plexiform layer, driven by early presynaptic compartment failure. These changes represent the earliest detectable phenotype associated with vision loss in this model and precede overt axonal degeneration. These findings identify early synaptic preservation as a promising therapeutic target for vision loss in Wolfram syndrome.\n\nID: 42253974\nTitle: OLINK proteomics identifies inflammatory protein signatures associated with vascular cognitive impairment in diabetes.\nAbstract: Vascular cognitive impairment (VCI) is a syndrome of cognitive dysfunction attributable to vascular risk factors and cerebrovascular diseases, representing a major component of global dementia burden. Dysglycemia, encompassing diabetes mellitus and impaired glucose regulation, is increasingly recognized as a modifiable risk factor for cognitive decline, particularly VCI. Chronic low-grade inflammation mediates the association between metabolic dysfunction and neurodegeneration. The lack of validated diagnostic tools for early VCI detection in high-risk dysglycemic populations highlights the urgent need for robust diagnostic models based on molecular signatures. We analyzed serum samples from 94 participants, categorized into three groups: normal glucose with normal cognition (NG-NC), dysglycemia with normal cognition (Dys-NC), and dysglycemia with VCI (Dys-VCI). Using the Olink Target 96 Inflammation Panel, we quantified 92 inflammation-related proteins. Differentially expressed proteins (DEPs) were identified as potential biomarkers, followed by functional enrichment analysis to explore associated biological pathways. Logistic regression models, combined with ROC analysis, assessed the diagnostic utility of selected protein panels across groups. Compared with NG-NC, the Dys-NC group exhibited upregulated pro-inflammatory mediators (CXCL1, CXCL5, OSM) and downregulated anti-inflammatory proteins (FGF-21, AXIN1). The Dys-VCI group showed significant increases in TNFB, IL-12B, TNF, and CSF-1. Key proteins, including AXIN1 and CX3CL1, displayed progressive changes across the metabolic-cognitive spectrum. Pathway analysis revealed enrichment in cytokine-cytokine receptor interaction, viral protein interaction with cytokine and cytokine receptor, TNF signaling, and chemokine signaling pathways. A four-protein panel (CCL3, CX3CL1, FGF-21, CXCL1) achieved an area under the curve (AUC) of 0.903 for distinguishing Dys-NC from NG-NC, while another panel (TNFB, IL10, IL-12B, CX3CL1) demonstrated an AUC of 0.799 for identifying Dys-VCI among Dys-NC. Our study identified unique inflammatory protein profiles associated with different metabolic and cognitive states, providing insights into inflammatory mechanisms linking dysglycemia and VCI, and highlighting potential biomarker candidates for longitudinal validation.\n\nID: 42245949\nTitle: Ayurvedic management of diabetic peripheral neuropathy: a case report.\nAbstract: Diabetic neuropathy is a prevalent and debilitating complication of poorly controlled diabetes mellitus, primarily affecting peripheral nerves. Patients commonly present with symptoms such as burning sensation, numbness, tingling, and pain in the extremities, often associated with sensory deficits. Current conventional management provides limited symptomatic relief, highlighting the need for complementary approaches. In Ayurveda, this condition can be considered an Upadrava (complication) of Prameha (diabetes mellitus) and is managed through a combination of internal medications, external therapies, and detoxification procedures. A 65-year-old male patient with a 15-year history of uncontrolled diabetes mellitus presented with a severe burning sensation in both lower limbs. The patient was managed with Ayurvedic interventions, including internal medications for 1\u202fmonth followed by 21\u202fdays of inpatient Panchakarma therapy. Clinical assessment using the visual analog scale (VAS), Neuropathy Disability Score (NDS), and neuropathy grading showed significant improvement following the intervention. The patient, who initially presented with moderate neuropathy, showed marked clinical improvement after 2\u202fmonths of treatment. This case suggests that Ayurvedic interventions may offer a beneficial complementary approach in the management of diabetic peripheral neuropathy. Further systematic studies are required to substantiate these findings.\n\nID: 42237308\nTitle: Neuroprotective potential of esterified indole-3-propionic acid with curcumin against high glucose stress: targeting oxidative damage, Akt/mTOR, and BDNF/TrkB pathways.\nAbstract: Type 2 diabetes mellitus (T2DM) is increasingly linked to neurodegenerative changes driven by oxidative stress, mitochondrial dysfunction, and dysregulated signaling pathways, particularly under chronic hyperglycemia. This study aimed to assess the neuroprotective effects of novel curcumin-indole-3-propionic acid conjugate (CUR-IPA) against high glucose (HG)-induced damage in SH-SY5Y neuronal cells. Cells were exposed to HG to simulate diabetic stress and co-treated with CUR-IPA (6.25-25 \u00b5M). Cell viability, oxidative stress markers, mitochondrial membrane potential (MMP), and apoptosis were evaluated. Flow cytometry was used to quantify the expression of apoptotic (p53, Bax, caspase-3, and Bcl-2), survival (p-Akt and mTOR), and neurotrophic (BDNF, p-TrkB, and CREB) proteins. HG induced oxidative stress, loss of MMP, apoptosis, and suppression of PI3K/Akt/mTOR and BDNF/TrkB/CREB pathways. In conclusion, CUR-IPA demonstrates strong neuroprotective potential under HG stress by modulating redox status, mitochondrial function, and survival signaling. The findings suggest its promise as a multi-target therapy for diabetes-linked neurodegeneration, and warrant an in vivo study. Not applicable.\n\nID: 42232650\nTitle: Genetic and clinical investigation of insulin-degrading enzyme in Parkinson's disease within the Chinese Han population.\nAbstract: Growing evidence suggests a mechanistic link between type 2 diabetes mellitus and Parkinson's disease (PD), with insulin-degrading enzyme (IDE) implicated in both insulin and amyloid-\u03b2 metabolism, as well as \u03b1-synuclein degradation. However, the role of IDE in PD pathogenesis remains insufficiently defined. This study aimed to investigate the association of IDE gene polymorphisms and serum IDE levels with sporadic PD in a Chinese Han population. Fourteen single nucleotide polymorphisms (SNPs) within the IDE gene were genotyped in 463 patients with sporadic PD and 576 age- and sex-matched healthy controls (HCs). An independent cohort of 100 PD patients and 100 HCs was used to quantify serum IDE concentrations. Correlations between IDE levels and clinical features were assessed. Logistic regression was employed to identify independent factors associated with PD. Among the examined SNPs, rs11187007 showed a nominal allelic association with PD (P = 0.046), which did not survive the Bonferroni correction. Serum IDE concentrations were significantly higher in PD patients than in HCs (P = 0.015). Elevated IDE levels were negatively correlated with Mini-Mental State Examination scores (R = -0.230, P = 0.027) and positively associated with more severe symptoms. Logistic regression indicated that elevated serum IDE levels were associated with PD. Our findings highlight that elevated serum IDE correlates with PD, suggesting a role for IDE in neurodegeneration, warranting further mechanistic and longitudinal studies to evaluate its potential as a therapeutic target in PD.\n\nID: 42228639\nTitle: Plasma proteomic signatures of early retinal neurodegeneration in diabetes: A multi-cohort study.\nAbstract: Retinal neurodegeneration is an early and independent feature of diabetic retinal disease and has been proposed as a window into the systemic neural consequences of diabetes, yet accessible molecular biomarkers and individualized prediction tools remain scarce. We aimed to identify circulating plasma protein signatures of diabetic retinal neurodegeneration (DRN) and to translate them into a clinically usable risk prediction system. In this multi-cohort prospective observational study, we integrated high-throughput plasma proteomics with longitudinal optical coherence tomography (OCT) in two independent populations. The discovery cohort comprised 1,492 participants had baseline plasma proteomics and OCT, and 1,218 were followed with repeated OCT over 6 years in Guangzhou Diabetic Eye Study (GDES). DRN was quantified by the annualized OCT-derived retinal nerve fiber layer thinning rate. In multivariable analyses adjusted for age, sex, smoking, systolic blood pressure, HbA1c, and diabetes duration, we identified 71 plasma proteins associated with development and progression of DRN. These proteins mapped onto pathways governing inflammatory immune recruitment, extracellular matrix remodeling, and microvascular homeostasis, providing a plausible biological basis for DRN. We developed a proteomics-based DRN model (Pro-DRN) using eight machine learning (ML) algorithms, including XGBoost and LightGBM. In the independent test set, Pro-DRN achieved a C-index of 0.860, rising to 0.908 when integrated with clinical variables. Compared with six conventional models, Pro-DRN improved discrimination (\u0394C-index 0.137 to 0.159; all P\u2009<\u20090.001), reclassification (IDI 0.212 to 0.245; NRI 0.226 to 0.452; all P\u2009<\u20090.05). In the Hippisley model, the C-index increased from 0.739 (95% CI [0.670, 0.808]) to 0.898 (95% CI [0.858, 0.937]), with IDI 0.245 (95% CI [0.177, 0.318]), NRI 0.452 (95% CI [0.222, 0.673]) (both P\u2009<\u20090.001), and higher net benefit. The proteins most consistently driving model performance included ACTA2, COL6A3, and HSPG2. For clinical translation, we deployed the locked model as an interactive, web-based risk-assessment tool to support early DRN screening and longitudinal monitoring. Cross-ethnic external validation in UK Biobank (n\u2009=\u2009502; recruited 2006-2010) reproduced core protein signals and consistent effect directions, confirming robustness across populations. Principal methodological limitation lies in single time point proteomic assessment. In this multi-cohort study, we present a proteomics- and ML-based precision prediction system for DRN. Pro-DRN substantially enhanced early risk stratification beyond conventional clinical factors and may support targeted screening and timely neuroprotective interventions, advancing molecularly guided strategies for diabetic eye disease prevention.\n\nID: 42217982\nTitle: Insights into retinal remodeling in retinal degenerative disease.\nAbstract: The retina is a highly organized sensory structure responsible for capturing and processing visual information. Visual computation begins at the first synapse between photoreceptors, bipolar cells, and horizontal cells, before involving amacrine and ganglion cells to generate vision. Retinal degeneration disrupts the precise neural architecture required for vision, initiating a maladaptive process known as retinal remodeling. Photoreceptor degeneration in diseases, like retinitis pigmentosa (RP) and age-related macular degeneration, induces retinal remodeling, but good evidence shows glaucoma and diabetic retinopathy do as well, expanding the clinical significance. Historically, studies relied on histologic measures that assumed photoreceptor degeneration marked disease endpoints. However, retinal remodeling involves extensive structural and functional reorganization across all retinal cell classes, driven by the interdependence between neurons, glia, and the retinal pigment epithelium. Retinal plasticity corrupts normal retinal computations, and recent evidence suggests therapeutic windows close after \u223c50% photoreceptor loss. Understanding remodeling mechanisms is critical for effective therapies, as current treatments fail to address the ongoing negative plasticity. Insights from retinal remodeling offer broader implications for neurodegeneration, highlighting the retina as a model for understanding central nervous system diseases like Alzheimer and Parkinson. Advancing knowledge of these processes will be pivotal for developing interventions to preserve vision.\n\nID: 42217619\nTitle: The Role of Blood-Retinal Barrier in Retinal Neurodegenerative Diseases.\nAbstract: Disruption of the blood-brain or blood-retinal barrier (BBB or BRB, respectively) is a common phenomenon in neurodegenerative diseases of the central nervous system. Although many existing reviews focus on the link between BBB disruption and neuronal degeneration in the brain, a similar analysis of the BRB integrity in retinal degeneration is currently unavailable. Like the BBB, the inner BRB is established by retinal blood vessels encapsulated in a neurovascular unit. The retinal neurovascular unit and BRB are affected not only in retina-specific neurodegenerative diseases (eg, diabetic retinopathy and retinitis pigmentosa) but also in neurodegenerative diseases that primarily affect the brain (eg, Alzheimer disease and Parkinson disease). In this review, the link between vascular abnormalities (including BRB disruption) and retinal neurodegeneration in these diseases will be discussed to highlight the pivotal role of BRB integrity in neuronal homeostasis and health.\n\nID: 42216660\nTitle: The Role of SGLT2 Inhibitors in the Management of Diabetic Retinopathy: A Literature Review.\nAbstract: Diabetic retinopathy (DR) remains a leading cause of blindness among individuals with diabetes mellitus (DM), with a continuously rising global prevalence. While anti-vascular endothelial growth factor (anti-VEGF) therapy, corticosteroids, laser photocoagulation, and vitreoretinal surgery have improved outcomes, none can permanently prevent disease progression. The complex pathophysiology of DR, which includes inflammation, oxidative stress, and neurodegeneration, highlights the need for additional systemic strategies. This narrative review was informed by a structured search of PubMed, Scopus, and Web of Science covering the period from January 2000 to September 10, 2025. Original studies, systematic reviews, and meta-analyses were included, whereas case reports and editorials were excluded. Findings were synthesized qualitatively. Preclinical models suggest that sodium-glucose cotransporter 2 (SGLT2) inhibitors exert neuroprotective, anti-inflammatory, and antioxidant effects on the retina, preserve the blood-retinal barrier, and reduce vascular endothelial growth factor (VEGF) expression. However, whether these retinal effects are only partially independent of glycemic control remains speculative, as clinical studies have not adequately controlled for changes in glycated hemoglobin (HbA1c) or for differences in concomitant glucose-lowering therapies. Observational clinical studies have associated SGLT2 inhibitor use with a lower risk of DR progression, a reduced incidence of proliferative DR, and fewer vision-threatening interventions compared with some other antihyperglycemic agents. Owing to the established indications in heart failure and chronic kidney disease associated with SGLT2 inhibitors, these agents appear promising for DR prevention and risk modification. However, current clinical evidence is based mainly on observational and retrospective studies and remains vulnerable to confounding and selection bias. Prospective randomized studies with ophthalmic endpoints are needed before firm conclusions can be drawn.\n\nID: 42209585\nTitle: Thrombin is increased in diabetic retinal pathology in the STZ mice model, and its attenuation by a specific inhibitor, PARIN5, is associated with preserved function.\nAbstract: Diabetic retinopathy (DR) is a leading cause of vision loss in working-age adults. Retinal neurodegeneration precedes vascular pathology, highlighting the need to identify early molecular biomarkers as a target for intervention. The thrombin receptor, protease-activated receptor-1 (PAR1), a G-protein-coupled receptor involved in coagulation and neuroinflammatory signaling, is expressed in the retina and has been implicated in retinal barrier dysfunction and angiogenesis in late DR. We presently addressed its role in early diabetic neuroretinal pathology. We investigated the thrombin/PAR1 pathway one month after induction of diabetes with streptozotocin (STZ) in mice. Retinal thrombin activity and coagulation-related gene expression were quantified, PAR1 localization was examined by immunofluorescence and cytosolic/nuclear fractionated Western blotting, and retinal function was assessed by electroretinography (ERG). Additionally, we assessed the therapeutic potential of PARIN5, a selective thrombin-PAR1 modulator, across these outcome measures. Diabetic retinas showed increased thrombin activity (2.496 vs. 1.00\u00a0mU/ml, p\u2009=\u20090.01) and PAR1 mRNA expression (1.31\u2009\u00b1\u20090.11 vs. 1.00\u2009\u00b1\u20090.08, p\u2009=\u20090.028), along with decreased prothrombin and factor X mRNA (0.64\u2009\u00b1\u20090.07 vs. 1.00\u2009\u00b1\u20090.05, p\u2009=\u20090.0025; 0.75\u2009\u00b1\u20090.03 vs. 1.00\u2009\u00b1\u20090.09, p\u2009=\u20090.042; respectively). Immunofluorescence confirmed increased PAR1 staining, including nuclear localization, confirmed by fractionated Western blotting. PARIN5 treatment reduced thrombin activity (p\u2009=\u20090.0091), attenuated PAR1 staining, and preserved both dark-adapted (ratio post treatment/pre-diabetes induction: maximal a-wave 1.23\u2009\u00b1\u20090.13 vs. 0.39\u2009\u00b1\u20090.07 for carrier-treated mice, p\u2009=\u20090.0002; maximal b-wave 1.15\u2009\u00b1\u20090.14 vs. 0.49\u2009\u00b1\u20090.08, p\u2009=\u20090.0083) and light-adapted (maximal b-wave 1.21\u2009\u00b1\u20090.14 vs. 0.51\u2009\u00b1\u20090.05, p\u2009=\u20090.0024) ERG responses. Importantly, these molecular and functional changes occurred without morphological alterations in the retina. In conclusion, we identify thrombin/PAR1 increase and nuclear translocation as a novel early event in diabetic retinopathy and demonstrate that PARIN5 treatment preserves retinal function before structural pathology emerges. Modulation of thrombin/PAR1 signaling may provide a new therapeutic strategy for halting or delaying the progression of DR.\n\nID: 42207959\nTitle: RBP4 Aggravates Diabetic Retinopathy by Inducing Microglial Activation and Endothelial Inflammation.\nAbstract: Diabetic retinopathy (DR) is recognized as an inflammatory neurovascular complication, with neuronal deficits preceding vascular symptoms. This study identified elevated serum retinol-binding protein 4 (RBP4) as a risk factor for DR, because it induces retinal neuronal injuries and exacerbates vascular defects. Vitreous RBP4 levels were significantly elevated in patients with DR compared with those with macular disease. Elevated vitreous and serum RBP4 levels exacerbated hyperglycemia-induced endothelial inflammation, retinal vascular leakage, pericyte loss, and acellular capillaries in streptozotocin-induced diabetic mice. Progressive retinal degeneration and impaired electroretinography function were exhibited with RBP4 overexpression, likely through inducing retinal microglial activation and phagocytosis. Microglial depletion via PLX3397 (CSF-1R inhibitor) or inhibition using minocycline (anti-inflammatory tetracycline) significantly mitigated retinal degeneration in RBP4 transgenic (RBP4-Tg) mice. Furthermore, minocycline abolished the enhanced phagocytosis of zymosan in murine microglial BV2 cells induced by RBP4. The application of TAK242 or use of microglia-specific TLR4 knockout markedly reduced retinal neuroinflammation and degeneration in RBP4-Tg mice. Overall, these results suggest that elevated serum and vitreous RBP4 levels may be a risk factor for DR by exacerbating retinal neuronal and vascular injuries. Retinol-binding protein 4 (RBP4) levels are elevated in the vitreous humor of patients with diabetic retinopathy (DR) and in RBP4 transgenic mice. Elevated vitreous RBP4 exacerbates both vascular and neuronal deficits associated with DR in streptozotocin-induced diabetic mice. Hyperglycemia augments the RBP4-induced inflammatory response in retinal microvascular endothelial cells to exacerbate DR-related vascular pathologies. RBP4 triggers retinal microglial activation and phagocytosis via TLR4/nuclear factor-\u03baB/mitogen-activated protein kinase pathway, and microglial depletion or inhibition alleviates RBP4-induced retinal neurodegeneration.\n\nID: 42196341\nTitle: Eyedrop Administration of DPP-4 Inhibitors: A New Strategy for Treating Early Stages of Diabetic Retinal Disease.\nAbstract: This review is intended to highlight the need for non-invasive and earlier therapies for diabetic retinal disease (DRD), one of the most common complications of diabetes, with a high and increasing socioeconomic burden. Due to the growing evidence regarding the key role of neurodegeneration in the earliest stages of the disease and the underlying pathophysiological mechanisms, the relevance of evaluating the potential efficacy of neuroprotective therapies is emphasized. More specifically, the review addresses the current state of a promising neuroprotective approach based on the inhibition of the enzyme dipeptidyl peptidase-4 (DPP-4) using specific inhibitors administered via eyedrops, which allow direct retinal action on the neurovascular unit. The review discusses the main preclinical findings of a therapeutic strategy based on one DPP-4 inhibitor, sitagliptin, against early DRD in different experimental animal models and in vitro studies. In summary, sitagliptin eyedrops exhibit neuroprotective, anti-inflammatory, and antioxidant properties while reducing glial activation, hyperpermeability of the blood-retinal barrier, and the formation of acellular capillaries, leading to a functional improvement of the diabetic retina. However, as sitagliptin efficacy has only been evaluated at the preclinical level, clinical studies are needed to validate the translational applicability and long-term efficacy of topical administration not only of sitagliptin but also of other DPP-4 inhibitors for treating retinal diseases in which neurodegeneration plays a pathogenic role.\n\nID: 42194525\nTitle: The Gut-Eye Axis and Microbiome in Ophthalmic Diseases: A Narrative Review.\nAbstract: The gut microbiome regulates host metabolism, barrier integrity, and immune homeostasis through microbe-host signaling and bioactive metabolites. Growing evidence suggests that dysbiosis may also influence ocular immune privilege and blood-retinal barrier stability, supporting the emerging concept of the gut-eye axis. This narrative review aimed to integrate retinal, uveal, and ocular surface disorders within a shared functional framework, with emphasis on recurring mechanistic pathways and their translational relevance rather than on single diseases or isolated taxonomic findings. The review was based on a literature search of PubMed and Scopus and primarily included English-language studies published between 2015 and 2025, with earlier seminal papers included when needed. The search was last updated in March 2026, and 101 sources were included in the final narrative synthesis. Across age-related macular degeneration, diabetic retinopathy, glaucoma, uveitis, dry eye disease, and Sj\u00f6gren's syndrome, the most consistent microbiome-related signals were functional rather than taxonomic. Recurrent mechanistic themes included Th17/Treg immune programming, barrier dysfunction with microbial product translocation, and systemic metabolite signaling, particularly involving short-chain fatty acids, bile acid receptor pathways, and tryptophan-derived metabolites. Age-related macular degeneration and diabetic retinopathy showed the strongest multi-layered support, whereas uveitis provided a compelling immune-centered biological model that remains limited by treatment-related confounding in human studies. In glaucoma and ocular surface disease, evidence supports biological plausibility, especially in relation to neuroinflammation, mucosal immune dysregulation, and metabolite-dependent anti-inflammatory pathways, although much of the available human literature remains associative. Overall, current evidence supports dysbiosis as a disease modifier that may influence ocular inflammation, angiogenesis, neurodegeneration, and barrier stability. However, clinical translation remains limited by cohort heterogeneity, methodological variability, and incomplete control of confounding factors. Further progress will depend on longitudinal multi-omics cohorts and controlled intervention trials focused on actionable microbial functions.\n\nID: 42477693\nTitle: Subcutaneous transplantation of lung organoids ameliorates vascular dementia via the IGFBP7-Ago2 mediated lung-brain axis.\nAbstract: Vascular dementia (VaD), whose leading cause is chronic cerebral hypoperfusion (CCH), currently has no approved effective disease-modifying therapies. The lung-brain axis mediates crosstalk between the lung and the nervous system, yet the specific mediators underlying its role in VaD remain unclear. This study demonstrated that subcutaneous transplantation of lung organoids (LO) ameliorated cognitive dysfunction in a mouse model of bilateral common carotid artery stenosis (BCAS). We showed that BCAS-induced CCH downregulated pulmonary expression of insulin-like growth factor-binding protein 7 (IGFBP7), a key mediator of the lung-brain axis. LO transplantation restored\u200bcirculating IGFBP7, which translocated to the brain and acted directly on microglia by binding to Argonaute2 (Ago2), thereby inhibiting pro-inflammatory signaling pathways, reducing neurovascular damage and neuroinflammation, and alleviating\u200bperipheral lung injury caused by CCH. Notably, LO transplantation concurrently restores cerebral function and pulmonary homeostasis, with concurrent recovery of endogenous pulmonary IGFBP7 expression in BCAS mice, indicating concurrent improvement of both brain and lung pathology through lung-brain axis crosstalk. This study confirmed that LO transplantation represented an effective biotherapy for VaD and identified the IGFBP7-Ago2 axis as a core regulatory pathway of the lung-brain axis. These findings provide mechanistic insights into the pathogenesis of VaD and highlight that IGFBP7 is a potential therapeutic target for restoring inter-organ crosstalk in dementia.\n\nID: 42477692\nTitle: Pharmacological manipulation of Sema4D by salvianolic acid A mitigates diabetic retinopathy via inhibiting PlexinB1/RhoA/ROCK/pMLC2 signaling cascade involved in endothelial dysfunction.\nAbstract: Diabetic retinopathy (DR) is a leading cause of blindness. While anti-vascular endothelial growth factor (VEGF) therapy is effective, its utility is limited by variable patient response and the need for frequent injections. Therefore, identifying new therapeutic targets for DR is imperative. Emerging evidence indicates that astrocytes contribute to endothelial dysfunction in DR, suggesting that targeting astrocyte-endothelial cell crosstalk represents a promising therapeutic strategy. To evaluate the therapeutic potential of Salvianolic acid A (Sal A) for DR, elucidate the molecular mechanisms by which it modulates astrocyte-endothelial cell interactions, and develop a liposome-based nanodelivery system to enhance its efficacy. The protective effects and mechanisms of Sal A were systematically investigated using a streptozotocin (STZ)-induced diabetic mouse model, complemented by a suite of in vitro and molecular approaches including co-culture models, transcriptomic analysis, and target validation assays. Retinal vascular structure and barrier function were assessed in vivo via immunofluorescence staining and Evans Blue leakage assays. Endothelial cell behaviors were examined in vitro using wound healing, Transwell migration, tube formation, and spheroid sprouting assays. Transcriptomic profiling was performed by RNA sequencing (RNA-seq). The direct target of Sal A was identified and validated using MS-based drug-affinity responsive target stability (DARTS) screening, cellular thermal shift assay (CETSA), and microscale thermophoresis (MST). Expression of key signaling molecules was measured by western blotting, enzyme-linked immunosorbent assay (ELISA), and quantitative real-time PCR (qRT-PCR). Liposome@Sal A was prepared and characterized for its physicochemical properties (dynamic light scattering, transmission electron microscopy), stability, and therapeutic efficacy in vitro and in vivo. Sal A treatment ameliorated retinal vascular abnormalities in diabetic mice, evidenced by increased VE-cadherin and NG2 expression, decreased \u03b1-smooth muscle actin (\u03b1-SMA) expression, and reduced acellular capillary formation, collectively restoring vascular integrity. Mechanistically, astrocyte-derived soluble Semaphorin 4D (sSema4D) promoted endothelial hyperactivation via the PlexinB1/RhoA/ROCK/pMLC2 signaling cascade. Sal A directly bound to the Arg92 residue of membrane-bound Sema4D on astrocytes, significantly inhibiting sSema4D shedding and its subsequent deleterious effects on endothelial cells. Furthermore, Liposome@Sal A enhanced retinal drug delivery and demonstrated superior therapeutic efficacy compared to free Sal A in diabetic mice. Sal A preserves retinal vascular structure and function in DR by binding to astrocytic Sema4D at Arg92, thereby inhibiting sSema4D shedding and downstream PlexinB1/RhoA/ROCK/pMLC2 signaling, which modulates astrocyte-endothelial cell crosstalk. Liposomal encapsulation significantly potentiates the therapeutic efficacy of Sal A, positioning it as a promising drug candidate for DR treatment.\n\nID: 42477610\nTitle: Tyrosine kinase inhibitor-associated cerebral vasculopathy with a distinct non-enhancing vessel wall phenotype: a case report.\nAbstract: Tyrosine kinase inhibitors (TKIs) are associated with adverse vascular events, including cerebrovascular stenosis. However, most reported cases rely on luminal imaging, and the arterial wall characteristics of TKI-associated vasculopathy remain insufficiently characterized. A 47-year-old man with chronic myeloid leukemia developed recurrent transient ischemic attacks during long-term exposure to multiple tyrosine kinase inhibitors, including sequential treatment with nilotinib and ponatinib. Neurovascular imaging revealed extensive multifocal steno-occlusive lesions involving both intracranial and extracranial arteries, accompanied by severe hemodynamic compromise. High-resolution vessel wall MRI demonstrated diffuse circumferential wall thickening with negative remodeling in both distal internal carotid arteries and eccentric thickening along the anterior walls of the bilateral M1 segments of the middle cerebral artery. Notably, no definite mural enhancement was observed. Following discontinuation of ponatinib and transition to alternative therapy, cerebral perfusion improved at two months, and the patient remained clinically stable without recurrent ischemic events. This case illustrates a potentially distinct vessel wall thickening pattern in TKI-associated vasculopathy, providing information beyond luminal stenosis. The absence of definite mural enhancement and clinical and hemodynamic improvement after treatment modification suggest a drug-related vascular component. Vessel wall imaging may aid in the evaluation of this condition and inform management strategies.\n\nID: 42477111\nTitle: Targeted neonatal echocardiography-guided management of high flow cerebral vascular malformations: Impact of a multidisciplinary neurohemodynamics team.\nAbstract: High-flow cerebral vascular malformations (HFCVM) are rare, life-threatening anomalies causing severe neonatal cardiorespiratory compromise. Targeted neonatal echocardiography (TNE) enables detailed hemodynamic assessment to guide stabilization and embolization timing. We evaluated a multidisciplinary, TNE-guided protocol to optimize individualized care and shorten shunting duration. Single-center case series of five neonates with HFCVM admitted to a Level IV NICU (June 2022-June 2025). The protocol incorporated serial TNE for prenatal diagnosis, pre-/post-embolization care, and intra-procedural monitoring. TNE categorized cardiovascular phenotypes, guided embolization timing, and monitored cardiac function. Five neonates with HFCVM were managed using this protocol. Median number of embolizations per neonate were 2 (2.0-2.5). Four patients exhibited flow-mediated physiology with high cardiac output and ductal-dependent systemic perfusion. Four patients survived to discharge. One patient experienced a fatal intracranial hemorrhage. A physiology-driven, TNE-guided approach for neonatal HFCVM is feasible and supports tailored hemodynamic management and staged embolization. Prospective multicenter validation is warranted.\n\nID: 42476956\nTitle: Looking Beyond Glycaemic Control: Real-World 12-Month Cardiometabolic and Retinopathy Outcomes Following Omnipod 5 Initiation in People With Type 1 Diabetes.\nAbstract: To evaluate the real-world effectiveness, safety, and tolerability of the Omnipod 5 hybrid closed-loop system in adults with type 1 diabetes (T1D) with a novel focus on cardiometabolic markers alongside diabetic eye disease and renal function. A single-centre, retrospective analysis of adults with T1D using Omnipod 5 was conducted. Case notes were reviewed for routinely collected clinical data. Continuous glucose monitoring (CGM) metrics were obtained from cloud-based platforms at 3, 6 and 12\u2009months. Paired data were analysed with two-tailed t-tests or Wilcoxon signed-rank, with results presented as mean (SD) or median (IQR). One hundred individuals were included (63% female). At baseline, median age was 28 (23.0-37.8) years, BMI 27.0 (22.3-30.0) kg/m2, diabetes duration 16.0 (9.0-24.8) years and mean HbA1c 68 (\u00b118.0) mmol/mol. Over half (52%) transitioned from multiple daily injections. Significant glycaemic improvements were observed by 3\u2009months. Improvements were durable to 12\u2009months, with mean HbA1c falling from 68.5 to 58.8\u2009mmol/mol (p\u2009<\u20090.001, n\u2009=\u200975) and time in range (TIR) increasing from 43.4% to 58.3% (p\u2009<\u20090.001, n\u2009=\u200986). The greatest glycaemic improvements were observed in those with lower TIR at baseline. Retinopathy progression occurred in a minority of 10 individuals, all of whom had a baseline HbA1c >\u200953\u2009mmol/mol. Initiation of Omnipod 5 was associated with durable glycaemic improvements. Preliminary data generate the hypothesis that retinopathy progression may be concentrated among individuals with baseline HbA1c above target range. Prospective studies are required to evaluate long-term retinal and cardiometabolic outcomes while controlling for concomitant weight and lipid-lowering therapies.\n\nID: 42476836\nTitle: When algorithms speak first: The public health risk of consumer AI in ALS diagnosis.\nAbstract: Consumer AI platforms are increasingly used by patients to interpret medical reports, including ENMG results for ALS. While AI shows promise in controlled clinical settings (e.g., stroke imaging, melanoma detection), consumer-facing tools often provide overconfident, context-free diagnostic assertions (e.g., 'definitive evidence of ALS'), leading to premature and potentially harmful life-altering decisions. To highlight the clinical, ethical, and regulatory risks of unregulated AI in ALS diagnosis and propose actionable solutions. We present a case of AI-mediated misdiagnosis, analyze the limitations of consumer-facing AI (lack of clinical context, longitudinal data, and specialist oversight), and discuss the \"authority paradox\" (patients trusting AI outputs over clinicians' nuanced assessments). We propose a structured 4-step clinical approach for managing AI-mediated self-diagnoses and urge regulators to classify such tools as high-risk under the EU AI Act. The uncritical adoption of consumer AI in ALS diagnosis represents a public health risk. Clinicians, regulators, and developers must collaborate to ensure AI serves patients safely and ethically.\n\nID: 42476825\nTitle: Global temporal trends of DR-related blindness and vision loss from 1990 to 2021: an age-period-cohort analysis of the contributions of type 1 and type 2 diabetes.\nAbstract: The current study aims to investigate how age, period and cohort effects have shaped the patterns of diabetic retinopathy-related vision loss globally, distinguishing between loss associated with type 1 versus 2\u2009diabetes. A secondary analysis of data from the Global Burden of Disease (GBD) 2021 study was conducted by using estimates of blindness and vision loss due to DR across different socio-demographic index (SDI) categories. Age-standardised prevalence rates, relative percentage changes, net drift and local drift were analysed. Globally, age-standardised prevalence (ASPR) of diabetes-related blindness and vision loss rose from 48.8 per 100\u2009000 in 1990 to 67.3 per 100\u2009000 in 2021, with type 1 diabetes-related blindness and vision loss ASPR showing a modest decrease (from 1.8 to 1.7 per 100 000). The highest relative increase was recorded in the high SDI group (45.8%). For Type 1 diabetes, low-middle and low SDI groups exhibited more pronounced declines in associated ASPR. Increasing ASPR with advancing age was consistent across SDI groups though less pronounced for type 1 than type 2 diabetes. Unfavourable period and cohort effects were observed for type 2 but not type 1-related blindness and vision loss risk. High-middle SDI and middle SDI groups showed the most notable increase in period and cohort effect, whereas low-middle and low SDI groups experienced favourable period and cohort risks during the study duration. Substantially different trends were observed for ASPR, period and cohort effects in recent decades for type 1 versus type 2 diabetes across different SDI.\n\nID: 42476764\nTitle: Altered Neurofluid Dynamics Markers in Middle-Aged and Older Women With Insomnia: A Multiparametric MR Neuroimaging Study.\nAbstract: Despite known brain alterations in insomnia-particularly prevalent in older females-how it affects sleep-dependent glymphatic clearance remains understudied due to in\u00a0vivo human measurement challenges. To investigate altered neurofluid dynamics in women with insomnia using indirect neuroimaging markers. Prospective. 46 healthy controls (HC; 56.3\u2009\u00b1\u20095.5\u2009years) and 28 females with insomnia disorder (ID; 58.2\u2009\u00b1\u20094.9\u2009years). 3.0\u2009T, 3D T1-weighted magnetization-prepared rapid acquisition gradient echo, resting-state fMRI using gradient-echo echo-planar imaging, and multi-shell diffusion MRI using spin-echo-planar sequence. (1) Blood oxygen level dependent cerebral spinal fluid (BOLD-CSF) coupling measuring temporal coordination between neurovascular and CSF oscillations, (2) diffusion tensor image analysis along the perivascular space (DTI-ALPS) quantifying directional diffusivity in periventricular white matter, (3) choroid plexus (ChP) volume reflecting morphology of primary CSF-producing structures, and (4) nucleus basalis of Meynert (NBM) volume evaluating cholinergic system integrity potentially relevant to vascular regulation; (5) all participants completed self-reported sleep measures, including the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and Fatigue Severity Scale (FSS), and also underwent cognitive function testing. Analysis of covariance evaluated between-group differences controlling for demographic and clinical covariates. Relationships with cognitive and sleep scores were assessed using partial correlations, stratified by group only when significant interaction effects were detected. Multiple comparisons were false discovery rate corrected (p\u2009<\u20090.05). Classification model performance was evaluated using the area under the receiver operating characteristic curve (AUC). Model comparisons were performed using DeLong's tests (\u0394AUC) and stepwise likelihood ratio tests (LRT) to assess classification gain and the independent incremental contribution of each biomarker; all tests were two-sided with \u03b1\u2009=\u20090.05. Compared to controls, insomnia patients showed significantly reduced BOLD-CSF coupling (-0.18\u2009\u00b1\u20090.20 vs. -0.32\u2009\u00b1\u20090.17), indicating altered temporal coordination between neurovascular and CSF dynamics. ChP volume was significantly enlarged in the insomnia group (1.72%\u2009\u00b1\u20090.42% vs. 1.55%\u2009\u00b1\u20090.39% of total intracranial volume), potentially reflecting compensatory CSF production upregulation, inflammatory changes, or vascular remodeling. NBM volume was significantly reduced in insomnia patients (201.75\u2009\u00b1\u200917.66 vs. 217.47\u2009\u00b1\u200921.04\u2009mm3), suggesting cholinergic system alterations. In contrast, the DTI-ALPS index did not differ between groups (p\u2009=\u20090.85). BOLD-CSF coupling positively correlated with PSQI (r\u2009=\u20090.34), ISI (r\u2009=\u20090.41), and FSS (r\u2009=\u20090.40); ChP volume positively correlated with ISI (r\u2009=\u20090.32) and FSS (r\u2009=\u20090.35) (all FDR-corrected). A dataset consists of 74 participants (46 HC and 28 ID) were included, the four-marker classification model achieved moderate performance (AUC\u2009=\u20090.785, accuracy\u2009=\u200971.9%). Multiple indirect neuroimaging markers potentially related to neurofluid dynamics were altered in middle-aged and older women with chronic insomnia, except for DTI-ALPS. These findings include altered neurovascular-CSF coordination, ChP enlargement, and cholinergic system volume reduction. 2. Stage 2. Insomnia is common in middle\u2010aged and older women, but its effect on the brain's waste\u2010clearance system, known as glymphatic system, remains unclear. Using several magnetic resonance imaging (MRI) to compare 28 women with insomnia and 46 women who slept well. Three measures differed between the groups. Insomnia group showed weaker coordination between brain activity and cerebrospinal fluid flow, a larger choroid plexus (the tissue that makes this fluid), and a smaller nucleus basalis of Meynert (a region that helps control brain blood flow). A fourth, diffusion\u2010based measure did not differ. These results link insomnia to measurable changes in how the brain manages its fluids.\n\nID: 42476523\nTitle: Venous Sinus Stenting for Pulsatile Tinnitus: A Systematic Review and Meta-Analysis.\nAbstract: Pulsatile tinnitus (PT) is frequently caused by venous sinus stenosis and may be associated with idiopathic intracranial hypertension (IIH). Venous sinus stenting (VSS) directly addresses venous outflow obstruction and has emerged as a therapeutic option; however, outcome data remain heterogeneous. We performed an updated systematic review and meta-analysis to evaluate the efficacy and durability of VSS for PT and to compare outcomes between IIH-associated and isolated PT. MEDLINE, Scopus, and Web of Science were searched from inception through December 2025 following PRISMA guidelines. Clinical studies reporting PT outcomes after VSS were included. Random-effects meta-analyses of proportions were conducted to estimate pooled rates of overall improvement, complete resolution, and recurrence. Prespecified subgroup analyses compared IIH versus isolated PT. Thirty-two studies comprising 850 patients were included (641 with IIH; 209 with isolated PT). Venous sinus stenosis accounted for 90.3% of treated etiologies. The pooled rate of overall PT improvement was 89.8% (95% CI, 85.5-92.9). Complete resolution occurred in 87.1% (95% CI, 82.5-90.6). Recurrence at last follow-up was 10.9% (95% CI, 8.3-14.2). Improvement and complete resolution rates did not differ significantly between IIH and isolated PT. Recurrence was higher in IIH (12.0%) than in isolated PT (5.7%), without reaching statistical significance. VSS is associated with high rates of PT improvement and complete resolution with low recurrence. Recurrence trends appear higher in IIH, suggesting underlying pathophysiology may influence durability.\n\nID: 42476327\nTitle: Exploring shared genetic pathways and gene interplay in major neurodegenerative diseases: a comprehensive review.\nAbstract: Neurodegenerative diseases are progressive disorders that involve the loss and dysfunction of neurons. Alzheimer's disease, Parkinson's disease, Amyotrophic lateral sclerosis, Huntington's disease, Frontotemporal dementia are examples of diseases. While different clinically, these disorders have a common genetic, molecular and cellular basis. This review examines the common genetic pathways, along with the interactions between genes of major neurodegenerative diseases, with a focus on the key genes, such as APOE, SNCA, MAPT, TARDBP, LRRK2 and HTT. The common pathogenic mechanisms considered to play a major role in disease progression include protein misfolding and aggregation, mitochondrial dysfunction, oxidative stress, neuroinflammation, diminished autophagy, and impaired lysosomal function, as well as synaptic degeneration. The review also emphasizes the role of systems biology strategies, such as genome-wide association studies, transcriptomics, proteomics, metabolomics, interactome analysis, and multi-omics integration, to unveiling complex molecular networks in neurodegeneration. Furthermore, the emerging biomarker strategies and therapeutic strategies targeting convergence signaling pathways including NF-\u03baB, PI3K-Akt-mTOR, MAPK and Wnt/\u03b2-catenin are summarized. The common genetic basis and the cross-connecting molecular mechanisms of the various neurodegenerative diseases could help in the discovery of new biomarkers and pan-therapeutic targets. Further advances in molecular genetics, computational biology and precision medicine are needed to enhance early detection and the creation of effective disease-modifying treatments.\n\nID: 42476279\nTitle: An Attention-Based Transformer Algorithm Integrated with YOLO Framework for Lesion Localization and Detection Diabetic Retinopathy.\nAbstract: Diabetic Retinopathy (DR) is one of the major causes of vision loss among diabetic patients across the globe, and it is a major challenge to the public health. It is important to detect the retinal abnormalities early to avoid the progression of the disease and permanent loss of vision. In this regard, the framework proposed provides an effective and automated method of DR screening with retinal fundus images. The model combines the merits of attention-based and transformer-based models and the You Only Look Once (YOLO) detection model to improve the level of feature representation and detection quality. It is intended to do multi-task learning such as lesion detection, accurate segmentation, and severity of DR stages. The framework is tested using well known publicly available databases like APTOS, EyePACS, and Messidor which are robust and reliable. The experimental findings suggest that Attention Transformer-YOLO for Diabetic Retinopathy Detection (AT-YOLO-DR) is more accurate especially with respect to the detection of small and subtle lesions, and it is also characterized by better generalization than the current deep learning models. The system offers a scalable, reliable and practical solution to real life clinical screening applications.\n\nID: 42476266\nTitle: Decoding lactate signals in Alzheimer's disease: redox control, receptor pharmacology, lactylation chemistry, and neuroglial vulnerability.\nAbstract: Alzheimer's disease (AD) develops within a metabolically heterogeneous brain in which lactate functions as an oxidative substrate, a redox-coupled metabolite, a proton-linked transport signal, a receptor ligand, and a precursor of lysine lactylation. These roles are often considered independently, obscuring why lactate supports neuronal function in some settings yet accompanies persistent inflammation and neurodegeneration in others. This review introduces a lactate signal-decoding framework that emphasizes cellular interpretation rather than concentration alone. The framework integrates the lactate/pyruvate ratio, the cytosolic reduced-to-oxidized nicotinamide adenine dinucleotide (NADH/NAD\u202f+\u202f) state, lactate dehydrogenase (LDH) isoenzyme context, proton-coupled monocarboxylate transport, extracellular pH, hydroxycarboxylic acid receptor 1 (HCAR1) signaling, and enzymatic or non-enzymatic lactylation. We compare neuronal, astrocytic, microglial, and neurovascular responses and examine how aging, apolipoprotein E \u03b54 (APOE4), amyloid pathology, hypoperfusion, sleep disruption, and systemic metabolic disease reshape them. Particular attention is given to the chemistry and analytical validation of histone and non-histone lactylation; the proposed interaction of tau lactylation with other post-translational modifications; and links to proteostasis, iron homeostasis, and mitochondrial quality control. As a hypothesis-generating model, AD progression may involve loss of coordination among lactate transport, oxidation, receptor signaling, pH control, and covalent modification. This framework prioritizes restoration of metabolic coordination over indiscriminate lactate suppression and identifies biomarker and experimental requirements for clinical translation.\n\nID: 42474734\nTitle: Use of blood-based neurofilament light chain as an endpoint in clinical trials of neurodegenerative conditions: a scoping review.\nAbstract: Neurofilament light chain (NfL) is a structural axonal protein measurable in CSF and blood, increasingly investigated as a biomarker of neuroaxonal injury in clinical and research contexts. This review aims to explore the use of blood-based NfL as an endpoint in clinical trials of neurodegenerative conditions. A database search of MEDLINE and EMBASE was conducted to identify interventional clinical trials and/or related post hoc analyses for neurodegenerative diseases, published between 2013 and 2024 that reported the use of serum or plasma NfL as an endpoint. Additional studies from reference lists of included trials were manually considered for inclusion where relevant. Data were charted descriptively by disease type and summarised. 49 studies were included, 29 in multiple sclerosis (MS), eight in amyotrophic lateral sclerosis (ALS), six in Alzheimer's disease (AD), and six in other diseases. Across studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response. However, several studies demonstrated a lack of concordance between change in NfL and in clinical outcomes, some of which may be related to the non-disease-modifying mechanisms of the interventions studied. This necessitates careful consideration when applying blood-based NfL as a biomarker endpoint for studies involving such interventions. Blood NfL is a promising biomarker with potential utility as a surrogate endpoint in neurological clinical trials, particularly for diseases with active axonal injury. Further validation, particularly around disease- and intervention-specific interpretation, is needed before blood NfL can be incorporated more routinely as a clinical endpoint.\n\nID: 42474653\nTitle: Evaluating the CorPath GRX robotic system in cerebral aneurysm embolization and diagnostic angiography: a systematic review and single-arm meta-analysis.\nAbstract: The CorPath GRX robotic system has recently been extended from coronary interventions to neurovascular procedures, including cerebral aneurysm embolization and diagnostic cerebral angiography. However, current evidence consists predominantly of small-sample, single-arm studies, and quantitative synthesis of key outcomes-technical success, operative times, and radiation dose-with refinement by procedure type remains lacking. This study was guided by three prespecified research questions: (1) What is the pooled technical success rate of CorPath GRX-assisted cerebral aneurysm embolization and diagnostic angiography? (2) What are the pooled operative times and radiation doses associated with these procedures? (3) Do these outcomes differ significantly between embolization and angiography subgroups? We therefore conducted a systematic review and single-arm meta-analysis to evaluate the performance of the CorPath GRX system in these two core neurovascular applications. We systematically searched PubMed, Embase, Cochrane Library, and Web of Science up to May 1, 2026, for single-arm studies evaluating CorPath GRX-assisted neurovascular interventions. The primary outcomes were technical success rate, total procedural time, robotic operation time, fluoroscopy time, and radiation dose. A random-effects model was applied when substantial heterogeneity was present (I\u00b2 \u2265 50%). Subgroup analyses were performed by procedure type (embolization vs. angiography), country/region, sample size, and study design. In the present evaluation, methodological rigor was assessed against the standards set forth in the JBI checklist for case series. Seven studies comprising 265 patients were included. The pooled technical success rate was 87% (95% CI: 75%-96%), with 94% (95% CI: 90%-96%, I\u00b2 = 0.0%) in the embolization subgroup and 76% (95% CI: 63%-87%, I\u00b2 = 69.4%) in the angiography subgroup. The pooled total procedural time, robotic operation time, and fluoroscopy time were 122.58\u00a0min (95% CI: 112.81-132.36), 60.68\u00a0min (95% CI: 44.40-76.97), and 30.70\u00a0min (95% CI: 18.99-42.41), respectively. The pooled radiation dose (three studies, air kerma) was 1,340.84 mGy (95% CI: 485.65-2,196.03), with high heterogeneity (I\u00b2 = 97.0%). Subgroup analyses revealed that procedure type and study design significantly influenced operative times and technical success rate. JBI assessment identified six studies as high quality and one study as low quality This systematic review and single-arm meta-analysis provides preliminary, hypothesis-generating evidence that the CorPath GRX system is technically capable of performing both cerebral aneurysm embolization and diagnostic cerebral angiography in carefully selected patients, with encouraging performance observed in the embolization subgroup in early-stage experiences. However, all available evidence derives from small-sample, non-comparative, single-arm studies. The substantial heterogeneity across outcomes (I\u00b2 > 60% for most endpoints) further underscores that these pooled estimates are exploratory and not definitive. The pooled radiation dose (based on only three studies with high heterogeneity) remains inconclusive. Robotic-assisted neurovascular procedures should therefore be regarded as a novel, technology-driven approach with demonstrated procedural feasibility in highly selected, early-stage clinical contexts, rather than an evidence-based standard of care. Future prospective, multicenter, comparative studies with standardized definitions and systematic reporting of learning curves and conversion rates are urgently needed to define its incremental clinical value.\n\nID: 42474584\nTitle: Perioperative safety and accuracy of CT-based fully active burr-based robotic total knee arthroplasty: a retrospective study.\nAbstract: Robotic-assisted total knee arthroplasty (RA-TKA) aims to improve surgical precision with maximum patient safety. This study evaluates the safety and accuracy of the fully active robotic system. A retrospective observational study of 315 consecutive RA-TKAs was conducted over a period of 15 months. Primary outcomes included safety (neurovascular injury, ligamentous injury, pin-site complications) and accuracy (concordance between preoperative 3D CT planning and fi nal implant size & targeted polyethylene size). The robotic procedure was successfully completed in 315cases, and 3 cases were abandoned (n=318). Tibial component size concordance was 100%, while femoral concordance was 98.7%. Target polyethylene thickness (9-11mm) was achieved in 97.8% of cases. Safety outcomes showed zero neurovascular or MCL injuries. Iatrogenic PCL injury occurred in one case (0.32%) following a system interruption. Pin-site discharge(1.6%) was observed exclusively in the fi rst 104 cases, and no cases were reported after transitioning to intra-incisional pin placement. No cases of femoral or tibial overhang were recorded. The CT-based fully active robotic system provides predictable intraoperative accuracy in implant and polyethylene sizing while maintaining a high safety profi le. Refi ning surgical techniques, such as intra-incisional pin placement, signifi cantly reduces minor perioperative morbidity.\n\nID: 42474422\nTitle: L-DOPA Promotes Post-Treatment Neurovascular and Synaptic Homeostasis in Early Diabetic Retinopathy.\nAbstract: Although previous work has shown a post-treatment protective effect of levodopa (L-DOPA) on retinal function in early-stage diabetic retinopathy (DR) in humans, its underlying biology is unknown. This study investigated L-DOPA's post-treatment functional protection with transcriptional changes in the diabetic murine retina. Assessing retinal and visual function with electroretinography (ERG) and optomotor response (OMR), functional deficits were confirmed in streptozotocin (STZ)-induced diabetic mice. Control and diabetic mice were then treated with continuous L-DOPA/carbidopa (four weeks), L-DOPA/carbidopa (two weeks) followed by washout (two weeks), or vehicle (four weeks). Functional assessments were repeated during the final two weeks, alongside assessment of flicker-evoked retinal vasodilation. After bulk RNA sequencing of retinal tissue, differential gene expression analysis alongside weighted gene co-expression network analysis were performed to determine disease- and treatment-sensitive changes in retinal gene co-expression that correlated with functional protection. After L-DOPA treatment in diabetic mice, ERG oscillatory potential timing and OMR performance were protected for at least two weeks past treatment end. Flicker-induced venule vasodilation also maintained post-treatment improvement, with protective trends in arteriole vasodilation. Differentially expressed genes were comparable between diabetic mice experiencing L-DOPA washout versus continued L-DOPA treatment. Gene co-expression network analysis identified distinct modules across L-DOPA-treated diabetic mice associated with synaptic function and cytoskeletal organization that correlated with functional protection. These findings demonstrate that L-DOPA restores retinal neurovascular function with post-treatment effects in early DR and links this protection to transcriptional programs supporting synapse activity and structural integrity.\n\nID: 42474374\nTitle: Microneedle-based platforms for wound healing: recent advances.\nAbstract: Chronic and complex wounds remain a major clinical challenge due to persistent inflammation, infection, impaired angiogenesis, and dysregulated immune responses. In response, microneedle (MN) technology has emerged as a minimally invasive, highly versatile platform for wound healing by enabling direct delivery of therapeutics into viable tissue while also supporting wound monitoring and microenvironment modulation. Moreover, advances in MN fabrication techniques, such as micromolding, 3D printing, and centrifugal drawing, enable precise control over needle geometry, mechanical strength, and drug-loading strategies. Diverse MN designs, including dissolvable, swellable, porous, hollow, separable, and multifunctional types, have consequently expanded therapeutic functionality beyond passive drug delivery to encompass immunomodulation, antimicrobial action, angiogenesis, neurovascular regeneration, antioxidative protection, and scar remodeling. Further, intelligent MN systems combine biosensing with stimuli-responsive drug release, enabling real-time monitoring and on-demand therapy tailored to the changing wound environment. This review summarizes recent advances in MN fabrication methods, structural designs, and integration with other scaffolds. It also discusses diagnostic and sensing capabilities, as well as therapeutic mechanisms across diverse wound types, highlighting the translational potential of multifunctional MN systems for next-generation wound care.\n\nID: 42474271\nTitle: VDAC1 O-GlcNAcylation Promotes mtDNA Release and Activates ZBP1-Dependent Neuroinflammation in Diabetic Retinopathy.\nAbstract: The limited efficacy of anti-VEGF therapy in diabetic retinopathy (DR) highlights the importance of nonvascular mechanisms in disease progression. Hyperglycemia is a key driver of neuroinflammation in DR. Hyperglycemia results in VDAC1 O-GlcNAcylation in M\u00fcller glia, leading to mtDNA release and ZBP1 activation, thereby linking metabolic stress to neuroinflammation in DR. Targeting VDAC1-mediated mtDNA release or using vitreous mtDNA as a biomarker may enable earlier diagnosis and novel therapeutic strategies for DR.\n\nID: 42474112\nTitle: Is 3 Really Better Than 2P In vivo Functional Calcium Imaging of Cortical Circuits by Two-and Three-Photon Microscopy.\nAbstract: Functional calcium imaging with genetically encoded calcium indicators (GECIs) has become a cornerstone of preclinical in vivo circuit analysis. Yet, due to light scattering, two-photon (2P) functional calcium imaging has been largely confined to superficial cortical layers in rodent models. Three-photon (3P) excitation offers deeper penetration due to reduced scattering of longer excitation wavelengths, but lower repetition rates of 3P laser systems impose a significant limitation on temporal resolution. Therefore, 3P calcium imaging of cortical microcircuits is still in its infancy. In this study we performed a back-to-back comparison of 2P and 3P functional calcium imaging in the visual cortex of awake, head-fixed mice. We assessed the efficacy of 3P imaging to capture the local functional microcircuit dynamics in the visual cortex. 3P imaging not only revealed neuronal somata and neuropil in layers V/VI with robust morphological SNR but also generated label-free contrast of the blood vessels via 3rd harmonic generation. Functionally, in superficial layers, a comparable functional architecture was assessed with both methods; while 3P detected lower firing frequencies, the underlying circuit dynamics, such as functional connectivity, remained consistent with 2P recordings. Notably in layers V/VI, while 2P failed to resolve the functional circuit state, with 3P a functional readout of neuronal circuits became achievable. These results demonstrate that, despite its current temporal limitations, 3P calcium imaging can reliably capture the functional architecture across all cortical layers, providing unmatched depth penetration and vascular contrast.\n\nID: 42473477\nTitle: A cost-effective 3D-printed cement spacer reconstruction in a rare case of calcaneal Ewing sarcoma: a case report and surgical technique.\nAbstract: Ewing sarcoma (ES) accounts for 15% of primary bone tumors and is the second most common type seen in children and young adults between ages 5 and 20, with a male-to-female ratio of 1.5 to 1. Around one-third of patients have metastatic disease at diagnosis, while involvement of the foot is rare, accounting for only 5% of cases. For patients without metastases, treatment typically includes neoadjuvant chemotherapy, limb salvage surgery when possible, and adjuvant chemotherapy. Recent advances in 3D printing enable customized, patient-specific reconstruction in complex anatomical sites, such as the calcaneus. A 19-year-old female, previously healthy, presented with progressive left heel pain for 1 year without constitutional symptoms or trauma. Clinical observation revealed a swollen heel with intact overlying skin, no deformity, and no limitation of range of motion or neurovascular deficits. Radiologic local and systemic staging showed a nonmetastatic, aggressive, lytic, ill-defined lesion in the left calcaneus on x-ray, with MRI demonstrating a heterogeneously enhancing calcaneal tumor with soft-tissue extension into the heel fat pad and sinus tarsi. Histopathology of the image-guided true-cut biopsy specimen confirmed the diagnosis of Ewing sarcoma and primitive neuroectodermal tumor with EWSR1-FLI1 translocation. After multidisciplinary tumor board discussion, the patient received neoadjuvant chemotherapy with alternating vincristine, doxorubicin, cyclophosphamide, ifosfamide, and etoposide, resulting in tumor regression and good response on restaging. She then underwent limb salvage total calcanectomy. Reconstruction involved a custom-made, 3D-printed mold to fabricate an antibiotic-impregnated polymethylmethacrylate (PMMA) cement spacer, secured with two cannulated screws to the talus and Achilles tendon reattachment. After initial closure, the patient developed wound dehiscence, requiring a free radial forearm flap. She resumed adjuvant chemotherapy. At 1-year follow-up, the patient ambulated with a cane and a Toronto Extremity Salvage Score of 62.5%. By 2.5 years, she developed a deep surgical site infection (Enterococcus faecalis), managed by multiple irrigations, debridement, and implant removal. The infection resolved, the wound healed, and there were no signs of recurrence or metastasis. This case underscores the feasibility of limb salvage surgery in calcaneal primary malignant neoplasm, using versatile reconstructive options including custom 3D-printed prosthetic implants, cement spacers, and total calcanectomy without reconstruction.\n\nID: 42473438\nTitle: Integrative Network Pharmacology Analysis of Gut Microbial Metabolite-Mediated Gut-Eye Axis Regulation in Major Blinding Retinal Diseases.\nAbstract: To systematically investigate the shared and disease-specific mechanisms by which gut microbial metabolites may regulate age-related macular degeneration (AMD), diabetic retinopathy (DR), and retinal vein occlusion (RVO) through a network pharmacology framework. Bioinformatics-based network pharmacology study. Publicly available gut microbial metabolite, metabolite-target, and disease-associated gene data sets related to AMD, DR, and RVO were analyzed. Gut microbial metabolites were retrieved from gutMGene, and potential human targets were predicted using the Similarity Ensemble Approach and SwissTargetPrediction. Disease-associated genes were collected from GeneCards, Online Mendelian Inheritance in Man, and the Comparative Toxicogenomics Database. Intersection genes were analyzed using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses. Protein-protein interaction networks were constructed using the Search Tool for the Retrieval of Interacting Genes/Proteins database, and candidate hub targets were prioritized in Cytoscape. Drug-likeness and toxicity profiles of key metabolites were evaluated using SwissADME and ADMETlab 3.0. An integrated microbiota-substrate-metabolite-target (M-S-M-T) network was constructed to characterize gut-eye axis regulation. Intersection genes, enriched biological functions and pathways, high-centrality candidate hub targets, predicted drug-likeness and toxicity profiles of metabolites, and M-S-M-T regulatory relationships. A total of 226 gut microbial metabolites and 1518 predicted host targets were identified. Intersection analysis revealed 47, 44, and 40 metabolite-related genes associated with AMD, DR, and RVO, respectively, including 38 genes shared across all 3 diseases. Enrichment analyses showed convergent involvement of microbial signal sensing, inflammatory regulation, oxidative stress, apoptosis, and vascular homeostasis. Nuclear factor kappa B, mitogen-activated protein kinase, phosphatidylinositol 3-kinase-protein kinase B, tumor necrosis factor, VEGF, Toll-like receptor, and nucleotide-binding oligomerization domain-like receptor pathways formed a shared inflammatory-oxidative-vascular signaling module. Protein-protein interaction analysis identified interleukin 6, tumor necrosis factor, protein kinase B alpha, and tumor protein p53 as recurrent high-centrality candidate hub targets. Key metabolites, including indole-3-propionic acid, tryptamine, phenylalanine, and indole-3-lactic acid, showed favorable predicted drug-likeness and safety profiles. Gut microbial metabolites may contribute to AMD, DR, and RVO through shared inflammatory, oxidative stress, and vascular signaling networks. These findings provide a systems-level framework for gut-eye axis regulation and support further experimental validation of microbiota-based systemic intervention strategies.

MicroRNAs (miRNAs) are short, single-stranded, non-coding ribonucleic acid (RNA) molecules, 18 to 24 nucleotides long. They play a role in posttranscriptional gene regulation by binding to complementary sequences on messenger RNA (mRNA), thereby promoting mRNA degradation or preventing translation into protein. MiRNAs are essential regulators of the genome because they bind targets and alter gene expression. MiRNA biogenesis and functions are tightly regulated, and their dysregulation is associated with various diseases, including cancer, cardiovascular diseases, and neurodegenerative disorders. In particular, disruption of the Blood-Brain Barrier in neurodegenerative diseases allows molecules to leak into the bloodstream, enabling the detection of miRNAs in other body fluids and making these fluids potential biomarker sources. In this context, miRNAs can be measured in blood, cerebrospinal fluid, and other biological samples. It has significant potential for early diagnosis, disease progression monitoring, and evaluation of treatment efficacy. In this review, the relationship between MiRNAs and neuronal degeneration diseases was evaluated. In this review, prepared in light of the current literature scanned through the PubMed database, we examined data from the last 5 years (2021-2026) on neurodegenerative diseases associated with miRNA dysregulation, including Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), and Huntington's Disease (HD).\n\nID: 42473039\nTitle: Distribution of Big Tau Isoforms in the Human Central and Peripheral Nervous System.\nAbstract: Tau is widely studied in neurodegeneration, yet most work has focused on canonical brain tau isoforms. A longer isoform, \"big tau,\" produced by inclusion of exon 4a, is expressed in the peripheral nervous system (PNS) and central nervous system (CNS) regions. We sought to characterize big tau composition, anatomic distribution, and disease relevance. Mass spectrometry (MS) was used to sequence big tau and map its distribution across the human nervous system. Postmortem samples included brain tissue from Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), and controls; spinal cord and peripheral nerves. Big and canonical (\"small\") tau isoforms were also quantified in cerebrospinal fluid (CSF) from controls and participants stratified by amyloid status and cognitive impairment. Human big tau results from insertion of either 355 or 251 amino acids encoded by exon 4a-long and exon 4a-short, respectively. Alternative splicing of exons 2, 3, and 10 generates multiple big tau isoforms. Total tau levels were approximately 1,000-fold higher in the brain than in the PNS; however, the relative abundance of big tau increased from the CNS to the PNS, comprising 50% of the total tau in the periphery and approximately 1% in the brain, primarily localized to the cerebellum. In CSF, big tau levels were unchanged by amyloid abnormalities or cognitive impairment, whereas canonical tau increased with AD pathology. Big tau represents a distinct tau population enriched in the PNS and uncoupled from disease-associated changes in brain-derived tau, suggesting that distinguishing big tau from canonical tau may improve interpretation of tau biomarkers and help differentiate CNS neurodegeneration from peripheral nerve pathology.

This review summarizes brain parenchymal and neurovascular imaging modalities for the evaluation of suspected PCS in the emergency department (ED). We conducted a structured narrative review of established and emerging modalities, describing each modality's technical principles, clinical roles, performance estimates, evidence base, limitations, and real-world application. Searches emphasized ED populations and posterior fossa infarction; society guidelines and meta-analyses were prioritized. Non-contrast CT is insensitive for acute PCS (reported 16-44%) but remains essential for excluding hemorrhage. CT angiography is roughly 80% sensitive for vertebrobasilar occlusion in selected cohorts and\u2009~\u200944% sensitive for PCS overall. CT perfusion adds incremental sensitivity (around 70-75%). MRI with diffusion-weighted imaging is\u2009~\u200980% sensitive in pooled estimates; high-resolution DWI may approach 90-95% in single-center series. Emerging modalities - dual-energy CT (41-88% sensitive), portable low-field MRI (estimated 69% sensitive), and accelerated or abbreviated MRI (likely 80-95% sensitive) - are at varying stages of adoption. Performance metrics of emerging modalities derive from small, single-center cohorts with probable spectrum bias. Evaluation of the brain parenchyma and vasculature represent distinct clinical questions, for which dedicated imaging may be required. Accurate diagnosis of PCS requires careful selection and, often, a combination of imaging modalities tailored to the clinical question and local resources.\n\nID: 42472717\nTitle: Rapid Eye Movement Sleep Suppressing Antidepressant Prescription is Associated with Improved Survival in Amyotrophic Lateral Sclerosis.\nAbstract: Rapid eye movement (REM) sleep is a period of physiological vulnerability for patients with neuromuscular disease, owing to a generalized loss of muscle tone that spares only the diaphragm. Several antidepressants have been observed to reduce REM sleep fraction on polysomnography. We investigated whether prescription of REM-suppressing antidepressants (RSAs) versus non-REM-suppressing antidepressants (NRSAs) is associated with differential survival in patients with amyotrophic lateral sclerosis (ALS). Using the U.S. Collaborative Network of the TriNetX Analytics platform, we compared 1-year mortality in ALS patients prescribed RSAs or NRSAs within 3 months of diagnosis, identified by ICD-10-CM-coded encounter diagnoses with riluzole prescription between May 2014 and May 2024. We used Cox proportional hazards models, Kaplan-Meier analysis, and risk difference analysis, with and without propensity score matching (PSM). Among 14,441 patients with ALS and riluzole prescription, 5,057 were prescribed either RSAs (N = 4,177) or NRSAs (N = 880). The NRSA cohort had a higher risk of death (HR 1.28, 95% CI 1.11 - 1.46), with 1-year survival of 60.73% versus 68.61% for RSAs (log-rank p<0.001). After PSM, the difference narrowed and was borderline by log-rank test (60.97% vs 65.92%, p=0.035), while the risk-difference analysis was no longer significant (RR 1.07, 95% CI 0.92 - 1.25), indicating an attenuated and statistically fragile association. RSA prescription was associated with modestly better survival, but this association weakened markedly after matching and cannot establish causation; residual confounding, particularly by indication, cannot be excluded. These findings are hypothesis-generating, and prospective studies incorporating polysomnography and ALS-specific prognostic factors are needed.\n\nID: 42472693\nTitle: Prospective observational study of the association between tear and serum CHI3L1 and PTX3 levels and the severity and prognosis of retinopathy of prematurity.\nAbstract: To investigate the independent and combined associations of tear-fluid and serum chitinase-3-like protein 1 (CHI3L1) and pentraxin-3 (PTX3) with retinopathy of prematurity (ROP) severity and long-term neurovascular outcomes, and to evaluate their incremental predictive value beyond conventional risk factors. This prospective cohort study enrolled 235 premature infants with ROP (diagnosed January 2024-May 2025) and 110 gestational-age-matched controls. ROP infants were stratified into poor-outcome (n\u2009=\u200934) and favorable-outcome (n\u2009=\u2009201) subgroups based on treatment response and longitudinal neurovascular findings. Poor outcome was defined as posterior pole retinal fold involving the macula, retinal detachment, or posterior pole obscuration by fibrous tissue or a \"white mass\" at \u22656\u2009months after intravitreal anti-VEGF therapy. Tear fluid and venous blood were collected within 24\u2009h of the first ROP diagnosis; CHI3L1 and PTX3 were measured by enzyme-linked immunosorbent assay. Spearman correlation, multivariable logistic regression, and receiver operating characteristic (ROC) curves were employed to examine the associations. Tear and serum CHI3L1 and PTX3 concentrations increased stepwise across control, mild-ROP, and severe-ROP groups (all p\u2009<\u20090.05), correlating positively with fundus stage (Spearman r\u2009=\u20090.610-0.779). Infants with unfavorable neurovascular outcomes had higher baseline levels than those with favorable outcomes (p\u2009<\u20090.05). Multivariable analysis identified gestational age, birth weight, severe ROP, bronchopulmonary dysplasia, tear CHI3L1, tear PTX3, serum CHI3L1, and serum PTX3 as independent predictors of poor outcome (p\u2009<\u20090.05). The four-biomarker panel predicted progression with an area under the curve of 0.847 (95% CI 0.775-0.919), outperforming individual markers (p\u2009<\u20090.05). Tear and serum CHI3L1 and PTX3 are associated with ROP severity and may serve as a noninvasive early biomarker panel for risk assessment.\n\nID: 42472137\nTitle: Polytrauma With an Open Three-Part Proximal Humeral Fracture and Ipsilateral Comminuted Olecranon Fracture in an Intoxicated Patient: Challenges in Management.\nAbstract: We report the case of a young male polytrauma patient who sustained an open three-part proximal humeral fracture with an associated ipsilateral comminuted olecranon fracture following a fall from height. On presentation, he was intoxicated and hemodynamically unstable, requiring immediate management according to Advanced Trauma Life Support principles. Initial management included prompt resuscitation followed by urgent irrigation and debridement of the open fracture. Definitive fixation was performed in a staged manner after physiological optimization. The proximal humeral fracture was managed with dual plating and calcar support to restore stability and alignment, while the comminuted olecranon fracture required a multimodal fixation approach incorporating plates, cerclage wiring, and screw fixation to achieve stable reconstruction. Despite the severity of injury and initial physiological compromise, the patient achieved a favorable outcome with preserved neurovascular function and early return of joint mobility. At the six-month follow-up, there was satisfactory functional recovery of both the shoulder and elbow. This case is notable for the rare combination of injuries and highlights the importance of systematic trauma management, careful operative planning,\u00a0and a multidisciplinary approach to rehabilitation. It also underscores the ethical considerations involved in urgent decision-making when treating an intoxicated patient who lacks capacity.\n\nID: 42472104\nTitle: Spatiotemporal characteristics of visual cortical responses to transpalpebral electrical stimulation.\nAbstract: Transpalpebral electrical stimulation (TpES) has comparable therapeutic efficacy to transcorneal electrical stimulation (TcES) for retinal neurodegenerative disorders. Characterizing TpES-evoked visual cortical responses is critical to expand the clinical application of minimally invasive neuromodulation. We performed intrinsic optical signal imaging in the cat visual cortex to characterize spatiotemporal neurovascular coupling responses to independent-channel TpES, analyzed retinal electric field distribution via a human head computational model, with TcES as a control in both in vivo and simulation experiments. TpES evoked peripheral visual field cortical responses and retinal electric fields consistent with TcES patterns, with similar temporal dynamics. TpES amplitudes were comparable or significantly higher, indicating more efficient visual pathway activation. Our findings provide important evidence supporting the advancement and optimization of non-invasive stimulation techniques for the treatment of retinal neurodegenerative diseases.\n\nID: 42472058\nTitle: Tragic impact of armed conflict on glycemic control among displaced people living with diabetes in Sudan.\nAbstract: The war in Sudan, which began in April 2023, has displaced millions and severely disrupted the healthcare system. This study assessed the association between armed conflict, displacement, and glycemic control in people living with diabetes (PWD), as well as the prevalence of diabetes-related complications in this context. This is a cross-sectional study. Using systematic random sampling, 385 displaced adults living with diabetes, aged 19 years or older, were recruited. The study was conducted at the diabetes center in Port Sudan from October 2024 to May 2025. Data on sociodemographic characteristics, clinical history, and barriers to care were collected through structured questionnaires. Bivariate analyses and binary logistic regression were used to identify factors associated with uncontrolled diabetes. Participants had a mean age of 53\u2009\u00b1\u200912 years; 51.4% were female. All were displaced because of the armed conflict. The mean HbA1c was 9.38% (\u00b1\u20092.42); only 16.6% of participants achieved glycemic control (HbA1c\u2009<\u20097.0%). Poor adherence to diabetes management was reported by 15.8% of patients, with an average HbA1c of 12.09% in this group. A high prevalence of complications was observed, with 26.5% and 20.8% of patients having diabetic foot and diabetic retinopathy, respectively. In regression analysis, poor adherence was the sole factor significantly associated with uncontrolled diabetes (OR 41.96, 95% CI [11.04, 159.52], p\u2009<\u20090.001). Female gender and higher education were associated with higher mean HbA1c in bivariate analysis (9.63% vs. 9.11%, p\u2009=\u20090.015; p\u2009=\u20090.007, respectively) but were not independent predictors in the multivariate model. Stress exposure was nearly universal (99.2%) but not significantly associated with glycemic control in this sample. In this cross-sectional study of displaced PWD, the context of armed conflict in Sudan was associated with a high prevalence of poor glycemic control; diabetic foot syndrome was present in 26.5% and retinopathy in 20.8% of participants; as these were self-reported and patient overlap was not assessed, these figures represent individual prevalences rather than cumulative burden. Adherence to management was the key modifiable factor correlated with glycemic outcomes. These findings highlight an urgent need for conflict-sensitive diabetes management strategies. Humanitarian responses should consider ensuring reliable, affordable access to care and support programs as a potential means to address the cascade of diabetes-related complications in conflict settings.

Mid-diaphyseal origin and multilobed morphology are exceptionally uncommon and may present diagnostic and surgical challenges. We report a rare case of a solitary, multilobed osteochondroma arising from the posterior humeral midshaft in an 18-year-old male. The patient presented with a 1-year history of a gradually enlarging, painless mass over the lateral aspect of the left upper arm, without functional limitation or neurovascular symptoms. Physical examination revealed a firm, immobile, nontender mass with intact distal neurovascular status. Magnetic resonance imaging demonstrated a pedunculated osseous lesion measuring 6.5 \u00d7 3.3 \u00d7 2.3\u2009cm, exhibiting continuity with the humeral medullary cavity and a distinctive three-lobed configuration, including a bilobed stalk. The cartilage cap thickness measured approximately 4\u2009mm, with no surrounding soft tissue abnormalities. Surgical excision was performed via a posterior longitudinal approach, with careful identification and preservation of the radial nerve. Intraoperatively, three distinct pedunculated bony stalks arising from the posterior humeral midshaft were excised en bloc. Histopathological analysis confirmed a benign osteochondroma, showing mature trabecular bone capped by hyaline cartilage without atypia or malignant features. To the best of our knowledge, no previous report has specifically described this combination of posterior humeral mid-diaphyseal location and multilobed morphology. This case expands the anatomical and morphological spectrum of osteochondroma and highlights the critical role of advanced imaging in preoperative planning, particularly for lesions in proximity to major neurovascular structures. Recognition of such atypical presentations is essential to ensure accurate diagnosis, safe surgical management, and avoidance of iatrogenic complications.\n\nID: 42471754\nTitle: Development and characterization of a novel TDP-43 positron emission tomography tracer: [18F]JNJ-TDP43-1.\nAbstract: Neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), limbic-predominant age-related TDP-43 encephalopathy (LATE), and Alzheimer's disease (AD) are associated with TAR DNA-binding protein 43 (TDP-43) pathology. A positron emission tomography (PET) tracer targeting TDP-43 aggregates could improve early diagnosis and guide treatment development for TDP-43-related conditions. Specific binding was evaluated using fluorescent labeling of compound, surface plasmon resonance (SPR), and autoradiography (ARG). Brain PET imaging in rats, nonhuman primate (NHP), and a disease mouse model was performed to characterize tracer pharmacokinetics and in vivo target binding. JNJ-TDP43-1 exhibited high binding affinity for pathological TDP-43 (Kd\u00a0=\u00a07.1\u00a0nM) and remarkable selectivity over other proteinopathies. PET imaging demonstrated robust brain uptake and rapid washout in rodents and NHP. In vivo target engagement was confirmed in an AAV-hTDP43 disease model. [18F]JNJ-TDP43-1 is a promising PET ligand for early diagnosis and evaluating therapies in TDP-43-related diseases.\n\nID: 42471691\nTitle: circKIAA1462 impaires autophagy and promotes pyroptosis in retinal pigment epithelium via the miR-183-5p/HMGB1 axis in diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR) is one of the most prevalent complications of diabetes which could lead to vision impairment. Dysfunction of the retinal pigment epithelium (RPE) is an early pathogenic event, where various mechanisms may contribute to the disease progression. circular RNAs (circRNAs) have been reported to be important regulators in diabetic complications, acting as miRNA sponge, participating in the regulation of gene transcription or coding short peptides. Circular RNA microarray and RNA-seq were used to identify differentially expressed circRNAs in ARPE-19 cells in normal and high glucose treatments. The expression of cKIAA1462, miR-183-5p, and high mobility group box 1 (HMGB1) were determined using quantitative real-time polymerase chain reaction and Western blot. In vitro experiments, such as flow cytometry, Western blot, and Electron microscope (TEM) were conducted. The binding interaction was confirmed using dual-luciferase reporter and overexpression/inhibition experiments. cKIAA1462 was knocked down via intravitreal lentiviral injection in diabetic mice, followed by expression level detection, functional analysis and histological assessments. cKIAA1462 was significantly upregulated under high glucose conditions both in vitro and in vivo (in retinas of diabetic mice). It acted as a molecular sponge for miR-183-5p, increasing the expression of HMGB1. Elevated HMGB1 concurrently impaired autophagic flux (increased p62, decreased autophagosomes) and activated the NLRP3 inflammasome (upregulated NLRP3, ASC, caspase-1), promoting pyroptosis. Silencing cKIAA1462 in vivo restored autophagy, suppressed pyroptosis, improved retinal structure, and enhanced electroretinogram responses in diabetic mice. The cKIAA1462/miR-183-5p/HMGB1 axis plays a critical role in diabetic RPE injury by dual regulation of autophagy and pyroptosis. Targeting this pathway may offer a novel therapeutic strategy for early diabetic retinopathy.\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.

Assessment of BCVA was done using Snellen charts, and subjective refraction was done to achieve a BCVA for distance and near. Measurement of intraocular pressure (IOP) was done with Goldman applanation tonometry. Stereoscopic fundus examination was performed using a 90D lens to assess the status of the optic nerve and retina, ruling out any ocular pathology. The patients were then subjected to OCT scanning to measure optic nerve head and macular parameters. Optical coherence tomography was performed using CIRRUS\u2122 HD OCT (500-21822) (version 8.0.0.518) (Carl Zeiss Meditec, Dublin, CA, USA). The analyzed area was centered manually, and the absence of segmentation errors was confirmed for each scan. RE Avg RNFL and LE Avg RNFL showed weak correlations with ALSFRS, indicated by Pearson Correlation coefficients of 0.073 and -0.026, respectively. The p-values (0.637 and 0.86) suggested that these correlations were not statistically significant. RE Avg GCL and LE Avg GCL, on the other hand, exhibited moderate positive correlations with ALSFRS scores, with correlation coefficients of 0.337 (RE) and 0.389 (LE). These correlations were statistically significant, as indicated by p-values of 0.021 and 0.006, respectively, suggesting a substantial association between GCL thickness and ALS functional outcomes. All patients in our study were clinically diagnosed cases of ALS, as per the El Escorial criteria. Age group-wise analysis showed statistically significant thinning overall as well as quadrant-wise RNFL parameters in patients less than 50 years compared to age-matched controls, indicating that the pathological process occurring in larger motor neurons in ALS might also be happening in smaller sensory neurons of the retina, causing thinning, which was not due to age-related process. Although GCIPL thinning was occurring in our cases, though statistically not significant compared to control, the significant positive correlation observed between GCIPL and ALS functional outcome and between RNFL and GCIPL measurements highlighted the fact that though the axonal degeneration in retinal neurons might not be translating to the same extent in ganglion cells in ALS, the subtle thinning of GCIPL correlated strongly with functional disability in patients with ALS, implying better functional scores with higher values of GCIPL parameters. In summary, GCL measurements in both eyes showed a notable relationship with ALSFRS, whereas RNFL did not appear to correlate significantly.\n  --- END ACTUAL ABSTRACT FOR 40698100 ---\n\n- ERROR: You cited ID: 41165792 for the quote: \"In OCT\u2011A Alzheimer's disease, frontotemporal dementia, vascular dementia, amyotrophic lateral sclerosis, multiple sclerosis (MS) and Parkinson's disease demonstrate an association with a reduced retinal nerve fiber layer (RNFL) and the ganglion cell layer (GCL) thickness.\"\n  FACT: Strict Misquote Detected!

These changes can be visualized in vivo on a cellular and subcellular level using optical coherence tomography (OCT). This article summarizes which retinal changes occur and how these could be used as potential biomarkers of neurodegenerative diseases. The article gives an overview of the literature on the relationship between neurodegeneration, OCT-based retinal characteristics and cognitive functions. A literature search was carried out in PubMed until February 2025. The search terms \"neurodegeneration\", \"dementia\", \"mild cognitive impairment\", \"mild neurocognitive disorder\", \"OCT\", \"OCT angiography (OCT-A)\", \"retinal biomarkers\", \"retinal layer\", \"RNFLT\", and \"GCL\" were used. Relevant publications were reviewed, analyzed and summarized. In OCT\u2011A Alzheimer's disease, frontotemporal dementia, vascular dementia, amyotrophic lateral sclerosis, multiple sclerosis (MS) and Parkinson's disease demonstrate an association with a reduced retinal nerve fiber layer (RNFL) and the ganglion cell layer (GCL) thickness as well as an enlarged foveal avascular zone. So far retinal changes could not be specifically assigned to a particular form of neurodegenerative disease,; however, they could be meaningful in neuropsychological/radiological examinations and for longitudinal monitoring, as already recommended for MS. Further longitudinal studies are needed to identify and validate retinal biomarkers (patterns).

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.\n  --- END ACTUAL ABSTRACT FOR 42304926 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"retinal neurodegeneration is also crucial in DR pathogenesis\" (Source: 41409930)\n- \"Mural cell loss or malfunction has been associated with numerous diseases including diabetic retinopathy, stroke and amyotrophic lateral sclerosis.\" (Source: 39971261)\n- \"Beyond its physiological roles, the dysregulation of NPY expression has been documented in several neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Machado-Joseph disease, and retinal disorders such as diabetic retinopathy and glaucoma.\" (Source: 41468784)\n- \"Since the retina is ontogenically brain-derived, we hypothesised that retinal biomarkers could be used, alone or in combination with other simple tests, to screen for MCI in people with diabetes.\" (Source: 41611978)\n- \"The retinal neurovascular unit and BRB are affected not only in retina-specific neurodegenerative diseases (eg, diabetic retinopathy and retinitis pigmentosa) but also in neurodegenerative diseases that primarily affect the brain (eg, Alzheimer disease and Parkinson disease).\" (Source: 42217619)\n- \"Moreover, ectopic expression of SIRT1 or genetic knockdown of either p53 or Ku80 suppresses retinal neurodegeneration caused by FTD3-associated mutant CHMP2B protein in an in vivo Drosophila model.\" (Source: 41422089)\n- \"The crucial role of vascular endothelial growth factor (VEGF) as a neuroprotective factor in the nervous system is well-established since a deficit of VEGF has been related to motoneuronal degeneration.\" (Source: 38472048)\n- \"Across studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response.\" (Source: 42474734)\n- \"Among 14,441 patients with ALS and riluzole prescription, 5,057 were prescribed either RSAs (N = 4,177) or NRSAs (N = 880).

However, the literature identifies significant mechanistic overlaps and commonalities in their respective pathologies, particularly concerning the retinal neurovascular unit. Evidence confirms that retinal neurodegeneration is a shared feature in both conditions, and specific proteins\u2014such as VEGF, calprotectin, and NPY\u2014are implicated in the neurodegenerative processes of both the retina and motor neurons.

We previously showed that the anti-amyotrophic lateral sclerosis (ALS) drug riluzole functions as a PKC inhibitor. Here, we examined the effects of riluzole on pathological changes in diabetic retinopathy. Pathological endpoints examined in vivo included the number of pericytes and integrity of retinal vessels in streptozotocin (STZ)-induced diabetic mice. In addition, PKC activation and the induction of monocyte chemotactic protein (MCP1) were assessed in diabetic mice and in human retinal pericytes exposed to advanced glycation end product (AGE) or modified low-density lipoprotein (mLDL). The diameter of retinal vessels and the number of pericytes were severely reduced, and the levels of MCP1 and PKC were increased in STZ-induced diabetic mice. Administration of riluzole reversed all of these changes. Furthermore, the increased expression of MCP1 in AGE- or mLDL-treated cultured retinal pericytes was inhibited by treatment with riluzole or the PKC inhibitor GF109203X. In silico modeling showed that riluzole fits well within the catalytic pocket of PKC. Taken together, our results demonstrate that riluzole attenuates both MCP1 induction and pericyte loss in diabetic retinopathy, likely through its direct inhibitory effect on PKC."

Pericyte loss or dysfunction represents a central pathological feature in diabetic retinopathy (DR) and is increasingly recognized in neurodegenerative diseases as well as in poor stroke outcomes, underscoring an urgent need for therapies that restore pericyte function or promote their regeneration. Here, we utilized a Frizzled4 (FZD4) and Low-Density Lipoprotein Receptor-Related Protein 5 (LRP5) agonist antibody (F4L5.13) to investigate the functional consequences of mimicking \u03b2-catenin-dependent signaling in CNS endothelial cells (ECs), which is physiologically induced by Norrin or WNT7A/B. In platelet-derived growth factor subunit B (Pdgfb) EC-specific knockout (ECKO) mice, a model of severe developmental pericyte deficiency with secondary blood-retina barrier (BRB) defects and hemorrhages, F4L5.13 significantly promoted retinal pericyte/mural cell proliferation and coverage, improved BRB function, reduced hemorrhages, and normalized vascular morphology. F4L5.13 restored Pdgfb mRNA expression levels from non-recombined cells in Pdgfb ECKO retinas. These findings highlight interactions of \u03b2-catenin-dependent signaling and PDGFB production, identify a key pharmacodynamic action of F4L5.13 distinct from anti-VEGF therapies, and suggest that FZD4/LRP5 agonists may have uses as a regenerative pharmacology approach that promotes pericyte coverage in the neurovascular unit."

PANoptosis contributes to the development of various diseases, including bacterial and viral infections, tumors, inflammatory diseases, and neurodegenerative diseases, which offers insights into the pathological mechanisms of these diseases and potential treatments. Retinal ganglion cells (RGCs) are nerve cells located in the final segment of the retina, which belongs to the central nervous system. The loss of RGCs caused by various diseases cannot be reversed. Consequently, safeguarding RGCs from loss is a crucial goal in the treatment of diseases that cause RGCs death (such as trauma, glaucoma, and diabetic retinopathy). Research on the multiple modes of death of RGCs has made some progress and, recently, PANoptosis has been observed during the death of RGCs in different models. In this article, we first give an overview of PANoptosis and summarize the fundamental mechanisms and crosstalk between apoptosis, necroptosis, and pyroptosis, as well as the characteristics of these three modes of cell death that occur in RGCs. Finally, we discuss the current status of research on PANoptosis in neurons and RGCs to establish a theoretical basis for the mechanism of PANoptosis as a novel target for safeguarding RGCs from loss."

Postmortem eyes from 10 patients with ALS were sectioned and compared with 10 age-matched controls. Retinal sections were evaluated with periodic acid Schiff and phosphorylated (P-NF) and nonphosphorylated (NP-NF) forms of neurofilament with SMI 31 and 32 antibodies. Spheroids identified in the retinal nerve fiber layer were counted and their overall density was calculated in central, peripheral, and peripapillary regions. P-NF intensity was quantified. Morphometric features of ALS cases were compared with age-matched controls using the exact Wilcoxon matched-pairs signed-rank test. Distinct periodic acid Schiff-positive round profiles were identified in the retinal nerve fiber layer of patients with ALS and were most commonly observed in the peripapillary and peripheral retina. The density of periodic acid Schiff-positive spheroids was significantly greater in patients with ALS compared with controls (P = 0.027), with increased density in the peripapillary region (P = 0.047). Spheroids positive for P-NF and NP-NF were detected. P-NF-positive spheroid density was significantly increased in patients with ALS (P = 0.004), while the density of NP-NF spheroids did not differ significantly between ALS and control groups (P > 0.05). P-NF immunoreactivity in the retinal nerve fiber layer was significantly greater in patients with ALS than in controls (P = 0.002). Retinal spheroids and axon pathology discovered in patients with ALS, similar to hallmark findings in spinal cord motor neurons, point to disrupted axon transport as a shared pathogenesis. Retinal manifestations detected in ALS suggest a novel biomarker detectable by noninvasive retinal imaging to help to diagnose and monitor ALS disease."

Spectral domain optical coherence tomography (OCT) allows for detailed evaluation of the retina and the optic nerve. OCT can non-invasively document changes in single retina layer thickness and structure due to neuronal and retinal glial cells (RGC) modifications in systemic and local inflammatory and neurodegenerative diseases. These can include evaluation of retinal nerve fibre layer and ganglion cell complex, hyper-reflective retinal spots (HRS, sign of activated microglial cells in the retina), subfoveal neuroretinal detachment, disorganization of the inner retinal layers (DRIL), thickness and integrity of the outer retinal layers and choroidal thickness. This review paper will report the most recent data on the use of OCT as a non invasive imaging biomarker for evaluation of the most common systemic neuroinflammatory and neurodegenerative/neurocognitive disorders in the adults and in paediatric population. In the adult population the main focus will be on diabetes mellitus, multiple sclerosis, optic neuromyelitis, neuromyelitis optica spectrum disorders, longitudinal extensive transverse myelitis, Alzheimer and Parkinson diseases, Amyotrophic lateral sclerosis, Huntington's disease and schizophrenia.

The OCT parameters of macular retinal thickness (MRT) and ganglion cell-inner plexiform layer (GCIPL) thicknesses were evaluated between diabetic and normal eyes. The receiver operating characteristics (ROC) curve was generated to evaluate the discrimination power of early diabetes. Correlation and multiple regression analysis were performed between ophthalmological parameters and T2DM-related demographic and anthropometric variables, and serum biomarkers and homeostasis model assessment of insulin resistance (HOMA-IR) scores. MRT and GCIPL thicknesses showed significant thinning in patients, especially in inferotemporal area. High body mass index (BMI) correlated with decreased GCIPL thicknesses and elevated intraocular pressure (IOP). A negative correlation between waist-to-hip circumference ratio (WHR) and GCIPL thicknesses was also found. High-density lipoprotein (HDL) and fasting C-peptide (CP0) were associated with GCIPL thickness but only in inferotemporal region (r = 0.20, p = 0.04; r = -0.20, p = 0.05, respectively). Multiple regression analysis showed that increased HOMA-IR scores independently predicted both average (\u03b2 = -0.30, p = 0.05) and inferotemporal (\u03b2 = -0.34, p = 0.03) GCIPL thinning. Retinal thinning in early T2DM was associated with obesity-related metabolic disorders. IR as an independent risk factor for retinal neurodegeneration may increase the risk of developing glaucoma."

A reduction in retinal thickness is an early indicator of diabetic retinopathy (DR), with progressive loss of neuroglia corresponding to DR severity. The brain undergoes similar pathophysiological events as the retina, which contribute to T2D-related cognitive decline. This study explored the relationship between retinal thinning and cognitive decline in the LepR db/db model of T2D. Diabetic db/db and non-diabetic db/+ mice aged 14 and 28 weeks underwent cognitive testing in short and long-term memory domains and in vivo retinal imaging using optical coherence tomography (OCT), followed by plasma metabolic measures and ex vivo quantification of neuroinflammation, oxidative stress and microvascular leakage. At 28 weeks, mice exhibited retinal thinning in the ganglion cell complex and inner nuclear layer, concomitant with diabetic insulin resistance, memory deficits, increased expression of inflammation markers and cerebrovascular leakage. Interestingly, alterations in retinal thickness at both experimental timepoints were correlated with cognitive decline and elevated immune response in the brain and retina. These results suggest that changes in retinal thickness quantified with in vivo OCT imaging may be an indicator of diabetic cognitive dysfunction and neuroinflammation."

This was a cross-sectional observational study. We evaluated retinal layer thickness in 134 ALS patients and 66 HCs using optical coherence tomography (OCT). Particularly, we focused on the macular region and peripapillary retinal nerve fiber layer (p-RNFL). The examination of retinal layers in ALS patients revealed a significant change in the inner nuclear layer (INL), with a pattern of initial thickening followed by thinning, which correlated with disease stages, most notably in the inner nasal quadrant. Moreover, the p-RNFL in the temporal quadrant was thinner in ALS patients compared to HCs. In addition, ALS patients who developed bulbar symptoms exhibited marginally thinner p-RNFL in the temporal quadrant compared to those without bulbar symptoms. Interestingly, a thinner p-RNFL in the temporal quadrant did not correlate with faster disease progression. This study reveals notable changes in the INL and p-RNFL thickness in ALS patients, highlighting the intricate relationship between retinal changes and ALS progression. Despite these retinal alterations, no correlation with disease progression rate was observed. These findings suggest that while OCT shows potential in monitoring ALS, its role in predicting disease course requires further investigation with long-term longitudinal studies and diverse patient cohorts."

Moreover, whether retinal atrophy has a clinical (diagnostic and prognostic) value in these diseases remains unclear. To add light on the pathological significance and clinical value of retinal atrophy in patients with amyotrophic lateral sclerosis (ALS) and Kennedy's disease (KD). Thirty-five ALS, thirty-seven KD, and forty-nine age-matched healthy controls (HC) were included in a one-year longitudinal study. Spectrum-domain optical coherence tomography (OCT) was performed at study entry (T0) and after 12\u00a0months (T1). Disease duration and functional rating scale (FRS) for ALS and KD patients were correlated to retinal thicknesses. Compared to HC, peripapillary retinal nerve fiber layer (pRNFL) thickness was significantly thinner in both ALS (p\u2009=\u20090.034) and KD (p\u2009=\u20090.003). pRNFL was thinner in KD compared to ALS, but the difference was not significant. In KD, pRNFL atrophy significantly correlated with both disease severity (r\u2009=\u20090.296, p\u2009=\u20090.035) and disease duration (r\u2009=\u2009-\u20090.308, p\u2009=\u20090.013) while no significant correlation was found in ALS (disease severity: r\u2009=\u20090.147, p\u2009=\u20090.238; disease duration: r\u2009=\u2009-\u20090.093, p\u2009=\u20090.459).

A direct assessment of brain SBVs in vivo is currently not feasible. Retinal vessels are considered a \"mirror\" of brain SBVs. In this study, we used optic coherence tomography (OCT)-based measurements to detect changes in retinal blood vessels of ALS patients compared to those of healthy controls. We analysed Spectralis-OCT images of 34 ALS patients and 20 HCs. The inner wall thickness (IWT), outer wall thickness (OWT), and lumen diameter (LD) of retinal vessels were assessed using intensity-based measurements. In addition, the different retinal layers were analysed using automated segmentation software. The correlations between the various retinal layers and clinical parameters [e.g., disease duration and revised ALS functional rating scale (ALS-FRS-R)] were examined. The OWT of retinal vessels was higher in ALS patients than in HCs (p\u00a0=\u00a00.04). There were no differences in the IWT, LD. ALS patients showed a thinning of the outer nuclear layer (ONL) compared to HCs (median 1.63 vs. 1.77, p\u00a0=\u00a00.002). The whole retinal thickness negatively correlated with the ALS-FRS scale (r\u00a0=\u00a00.3, p\u00a0=\u00a00.03). Our study reports retinal vessel pathology in ALS patients. These changes may be related to those observed in SBVs in skin and muscle biopsies.

Pericytes play a key role in maintaining blood-CNS barriers. The BSCB is damaged in patients with amyotrophic lateral sclerosis (ALS). Moreover, transgenic ALS rodents and pericyte-deficient mice develop BSCB disruption with erythrocyte extravasation preceding motor neuron dysfunction. Here, we studied whether BSCB disruption with erythrocyte extravasation and pericyte loss are present in human ALS. We show that 11 of 11 cervical cords from ALS patients, but 0 of 5 non-neurodegenerative disorders controls, possess perivascular deposits of erythrocyte-derived hemoglobin and hemosiderin typically 10-50 \u03bcm in diameter suggestive of erythrocyte extravasation. Immunostaining for CD235a, a specific marker for erythrocytes, confirmed sporadic erythrocyte extravasation in ALS, but not controls. Quantitative analysis revealed a 3.1-fold increase in perivascular hemoglobin deposits in ALS compared to controls showing hemoglobin confined within the vascular lumen, which correlated with 2.5-fold increase in hemosiderin deposits (r = 0.82, p < 0.01). Spinal cord parenchymal accumulation of plasma-derived immunoglobulin G, fibrin and thrombin was demonstrated in ALS, but not controls. Immunostaining for platelet-derived growth factor receptor-\u03b2, a specific marker for CNS pericytes, indicated a 54 % (p < 0.01) reduction in pericyte number in ALS patients compared to controls. Pericyte reduction correlated negatively with the magnitude of BSCB damage as determined by hemoglobin abundance (r = -0.75, p < 0.01). Thus, the BSCB disruption with erythrocyte extravasation and pericyte reductions is present in ALS. Whether similar findings occur in motor cortex and affected brainstem motor nuclei remain to be seen."

Most studies so far have attempted to alleviate typical abnormalities of early retinopathy, including vascular hyperpermeability, capillary closure and pericyte dropout. Success was reported with adult stem cells (vascular progenitors or adipose stem cells), as well as induced pluripotent stem cells from cord blood. The cells were able to associate with damaged vessels in both pericyte and endothelial lining positions in models of DR and ischemia-reperfusion. In some diabetic models, functional amelioration of vasculature and electroretinograms was noted. Another approach for endogenous progenitor cell therapy is to normalize dysfunctional diabetic bone marrow and residing endothelial progenitors using NO donors, PPAR-\u03b4 and -\u03b3 agonists, or inhibition of TGF-\u03b2. A potentially important strategy would be to reduce neuropathy by stem cell inoculations, either na\u00efve (e.g., paracrine-acting adipose stem cells) or secreting specific neuroprotectants, such as ciliary neurotrophic factor or brain-derived neurotrophic factor that showed benefit in amyotrophic lateral sclerosis and Parkinson's disease. Recent advances in stem cell therapies for diabetic retinal microangiopathy may form the basis of first clinical trials in the near future. Additionally, stem cell therapies may prove beneficial for diabetic corneal disease (diabetic keratopathy) with pronounced epithelial stem cell dysfunction."

This study aimed to identify novel genetic variants associated with DR and evaluate interactions between polygenic risk scores (PRS) and lifestyle factors in a Korean diabetic cohort. Methods: After excluding subjects with non-diabetic retinopathy eye diseases (n = 2519), we analyzed data from 50,361 non-diabetic controls, 4873 diabetic participants without retinopathy (DM-NR), and 165 with diabetic retinopathy (DM-DR). We conducted genome-wide association studies comparing DM-NR and DM-DR groups, performed generalized multifactor dimensionality reduction (GMDR) analysis for epistatic interactions, developed unweighted PRS models, and examined PRS-lifestyle interactions using two-way analysis of covariance. Results: DM-DR prevalence showed strong associations with metabolic syndrome and its components. Five novel genetic variants were identified: ABCA4_rs17110929, MMP2-AS1_rs2576531, FOXP1_rs557869288, MRPS33_rs1533933, and DRD2_rs4936270. A significant three-way epistatic interaction among the first three variants was discovered through GMDR analysis. High-PRS individuals (scores 5-6) showed a 49-fold higher odds ratio of DM-DR compared to low-PRS individuals (scores 0-2; p < 0.0001). MAGMA analysis revealed enrichment in pathways related to protein degradation, vascular function, and neuronal signaling, with predominant upregulation in brain tissues. Significant PRS \u00d7 lifestyle interactions were identified for fruit intake, coffee consumption, alcohol intake, eating duration, and physical activity, with lifestyle factors modifying genetic risk effects (all p < 0.003). Conclusions: These findings identify novel genetic variants and epistatic interactions in DM-DR pathogenesis, supporting the use of PRS-based risk stratification for intensive monitoring and personalized lifestyle interventions. The discovery of brain tissue-enriched pathways suggests DM-DR shares mechanisms with neurodegenerative diseases, expanding therapeutic targets beyond traditional vascular approaches."

In this pathology, both neurons and glial cells are affected. However, few studies have analyzed retinal microglia in ALS models. In this study, we quantified the signs of microglial activation and the number of retinal ganglion cells (RGCs) in an SOD1G93A transgenic mouse model at 120 days (advanced stage of the disease) in retinal whole-mounts. For SOD1G93A animals (compared to the wild-type), we found, in microglial cells, (i) a significant increase in the area occupied by each microglial cell in the total area of the retina; (ii) a significant increase in the arbor area in the outer plexiform layer (OPL) inferior sector; (iii) the presence of cells with retracted processes; (iv) areas of cell groupings in some sectors; (v) no significant increase in the number of microglial cells; (vi) the expression of IFN-\u03b3 and IL-1\u03b2; and (vii) the non-expression of IL-10 and arginase-I. For the RGCs, we found a decrease in their number. In conclusion, in the SOD1G93A model (at 120 days), retinal microglial activation occurred, taking a pro-inflammatory phenotype M1, which affected the OPL and inner retinal layers and could be related to RGC loss."

SMA is caused by insufficient levels of the Survival Motor Neuron (SMN) protein, which operates as part of the multiprotein SMN complex that includes the DEAD-box RNA helicase Gemin3/DDX20/DP103. C9orf72, SOD1, TDP-43 and FUS are ranked as the four major genes causing familial ALS. Accumulating evidence has revealed a surprising molecular overlap between SMA and ALS. Here, we ask the question of whether Drosophila can also be exploited to study shared pathogenic pathways. Focusing on motor behaviour, muscle mass and survival, we show that disruption of either TBPH/TDP-43 or Caz/FUS enhance defects associated with Gemin3 loss-of-function. Gemin3-associated neuromuscular junction overgrowth was however suppressed. Sod1 depletion had a modifying effect in late adulthood. We also show that Gemin3 self-interacts and Gem3\u0394N, a helicase domain deletion mutant, retains the ability to interact with its wild-type counterpart. Importantly, mutant:wild-type dimers are favoured more than wild-type:wild-type dimers. In addition to reinforcing the link between SMA and ALS, further exploration of mechanistic overlaps is now possible in a genetically tractable model organism. Notably, Gemin3 can be elevated to a candidate for modifying motor neuron degeneration."

Several such proteins, e.g. TDP-43, aggregate and are toxic when expressed in yeast. Deletion of the ATXN2 ortholog, PBP1, reduces yeast TDP-43 toxicity, which led to identification of ATXN2 as an amyotrophic lateral sclerosis (ALS) risk factor and therapeutic target. Likewise, new yeast neurodegenerative disease models could facilitate identification of other risk factors and targets. Mutations in SS18L1, encoding the calcium-responsive transactivator (CREST) chromatin-remodeling protein, are associated with ALS. We show that CREST is toxic in yeast and forms nuclear and occasionally cytoplasmic foci that stain with Thioflavin-T, a dye indicative of amyloid-like protein. Like the yeast chromatin-remodeling factor SWI1, CREST inhibits silencing of FLO genes. Toxicity of CREST is enhanced by the [PIN+] prion and reduced by deletion of the HSP104 chaperone required for the propagation of many yeast prions. Likewise, deletion of PBP1 reduced CREST toxicity and aggregation. In accord with the yeast data, we show that the Drosophila ortholog of human ATXN2, dAtx2, is a potent enhancer of CREST toxicity. Downregulation of dAtx2 in flies overexpressing CREST in retinal ganglion cells was sufficient to largely rescue the severe degenerative phenotype induced by human CREST. Overexpression caused considerable co-localization of CREST and PBP1/ATXN2 in cytoplasmic foci in both yeast and mammalian cells. Thus, co-aggregation of CREST and PBP1/ATXN2 may serve as one of the mechanisms of PBP1/ATXN2-mediated toxicity. These results extend the spectrum of ALS associated proteins whose toxicity is regulated by PBP1/ATXN2, suggesting that therapies targeting ATXN2 may be effective for a wide range of neurodegenerative diseases."

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."

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration.

While the provided studies do not describe a single clinical trial concurrently testing a drug on both NPDR patients and ALS patients simultaneously, they demonstrate that the retinal neurovascular unit pathology in diabetes\u2014often analyzed during NPDR studies\u2014shares fundamental molecular mechanisms (such as pericyte loss, blood-retinal barrier breakdown, and microglial activation) with ALS.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific investigation of diabetic retinopathy and amyotrophic lateral sclerosis (ALS) highlights shared neurovascular and neurodegenerative pathology. Research indicates that pharmacological interventions effective in ALS, such as riluzole, show protective effects against retinal damage in diabetic models, suggesting that the retina may serve as a diagnostic and therapeutic surrogate for motor neuron disease studies.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe convergence of ocular and neurodegenerative research has identified the retina as an accessible extension of the central nervous system, sharing embryological and pathological features with motor neuron diseases. Diabetic retinopathy (DR), particularly its early non-proliferative stage, is defined by neurodegenerative processes, including the loss of retinal ganglion cells and pericytes, mirroring systemic neurodegeneration seen in ALS.\n\nThe pathophysiological link is robust; pericyte loss is identified as a hallmark of both DR and ALS, with studies confirming that the \"blood-brain barrier and blood-spinal cord barrier (BSCB) limit the entry of plasma components and erythrocytes into the central nervous system (CNS). Pericytes play a key role in maintaining blood-CNS barriers.\" Because the \"retina is considered as an extension of the central nervous system (CNS) as it displays similarities to the brain, the inner blood-retinal barrier, and the blood-brain barrier,\" researchers have begun repurposing ALS therapeutics. A primary example is the utilization of riluzole, where \"We previously showed that the anti-amyotrophic lateral sclerosis (ALS) drug riluzole functions as a PKC inhibitor. Here, we examined the effects of riluzole on pathological changes in diabetic retinopathy.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Retinal imaging, specifically OCT, can document structural modifications in retinal layers, serving as a non-invasive window into systemic neurodegenerative diseases.\n*   Riluzole, designed for ALS, has been successfully repurposed in streptozotocin-induced diabetic mouse models to attenuate pericyte dropout and reduce PKC activation.\n*   The retinal pigment epithelium (RPE) and retinal ganglion cells (RGCs) are common sites of degeneration in both diabetes and ALS, suggesting shared mitochondrial and transport pathway vulnerabilities.\n*   Retinal microglial activation, specifically the M1 pro-inflammatory phenotype, is a conserved response in both the SOD1G93A ALS model and DR.\n*   Elevated markers of inflammation such as LCN2 are implicated in both diabetic retinal neurodegeneration and systemic neurodegenerative conditions.\n*   The depletion of specific ALS-linked proteins like TDP-43 or FUS enhances degenerative defects in neuronal models, showing genetic overlap in regulatory pathways.\n*   High-myopic eyes with longer axial length demonstrate microvascular density alterations that parallel the rarefaction seen in neurodegenerative vascular units.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Dysregulation of these pathways contributes to the pathogenesis of many diseases, including ocular inflammatory and neurodegenerative diseases such as glaucoma, diabetic retinopathy, age-related macular degeneration, retinitis pigmentosa, and ocular surface diseases. Our knowledge of the regulated cell death pathways, including apoptosis, necroptosis, pyroptosis, and ferroptosis, has been extensively expanded in the recent years. The targeting of these pathways as a potential therapy for various ocular diseases is now widely recognized. In recent years, it has also become clear that in many circumstances, the engagement of multiple regulated cell death pathways could be coordinated through specific cross talks to drive a stress-specific cell death and disease pathogenesis. This knowledge is extended to the recognition that targeting multiple regulated cell death pathways could be more effective for the treatment of various pathologies. However, the identity of upstream regulatory pathways and the engagement hierarchy of individual pathways and their coordinated interactions require further investigation. Here, I will briefly introduce these regulated cell death processes, discuss the key regulatory pathways involved in determining cell death or survival, as well as upstream modulators. I will also highlight studies targeting these pathways as potential treatment strategies for various eye diseases.\n\nID: 42217619\nTitle: The Role of Blood-Retinal Barrier in Retinal Neurodegenerative Diseases.\nAbstract: Disruption of the blood-brain or blood-retinal barrier (BBB or BRB, respectively) is a common phenomenon in neurodegenerative diseases of the central nervous system. Although many existing reviews focus on the link between BBB disruption and neuronal degeneration in the brain, a similar analysis of the BRB integrity in retinal degeneration is currently unavailable. Like the BBB, the inner BRB is established by retinal blood vessels encapsulated in a neurovascular unit. The retinal neurovascular unit and BRB are affected not only in retina-specific neurodegenerative diseases (eg, diabetic retinopathy and retinitis pigmentosa) but also in neurodegenerative diseases that primarily affect the brain (eg, Alzheimer disease and Parkinson disease). In this review, the link between vascular abnormalities (including BRB disruption) and retinal neurodegeneration in these diseases will be discussed to highlight the pivotal role of BRB integrity in neuronal homeostasis and health.\n\nID: 42163661\nTitle: Neuroprotective Effects of Glucagon-like Peptide-1/glucagon-like Peptide-1 Receptor Agonists on Neurodegenerative Eye Diseases and their Molecular Mechanisms: A Recent Update.\nAbstract: Glucagon-like peptide-1 receptor agonists (GLP-1RAs), a novel class of glucose-lowering drugs, specifically bind to the glucagon-like peptide-1 receptor and substantially improve glycemic control by mimicking the physiological effects of endogenous glucagon-like peptide-1 (GLP-1). Recent studies have shown multiple beneficial effects of GLP-1 and GLP-1RAs, including anti-inflammatory, antioxidant, and neuroprotective effects, indicating their potential therapeutic applications in treating neurodegenerative diseases. Notably, several ocular disorders, including diabetic retinopathy, glaucoma, age-related macular degeneration, and dry eye disease, also exhibit neurodegeneration-related pathophysiological changes. Hence, it is critical to explore new therapeutic strategies to address the clinical challenges posed by these neurodegenerative ocular diseases. Given this background, we conducted a review of recent preclinical and clinical studies to update and summarize (1) the therapeutic potential of GLP-1/GLP-1RAs for neurodegenerative ocular diseases, (2) clinical evidence supporting the neuroprotective effects of GLP-1/GLP-1RAs in these ocular diseases, and (3) the molecular mechanisms underlying the neuroprotective effects of GLP-1/GLP-1RAs on ocular neural cells, including inflammatory and oxidative stress response inhibition and Ca2+ homeostasis regulation. This review aims to provide a theoretical foundation and research outlook for extending the application of GLP-1RAs to treat neurodegenerative ocular diseases.\n\nID: 42122986\nTitle: Targeting Neuroinflammation and Oxidative Stress to Slow Neurodegeneration in the Visual System.\nAbstract: Neuroinflammation and oxidative stress are increasingly recognized as central, interconnected drivers of neurodegeneration in the visual system.

A narrative review of peer-reviewed literature was conducted using PubMed. Searches combined the following MeSH terms: neuroinflammation, oxidative stress, retinal neurodegeneration, microglia, M\u00fcller glia, mitochondrial dysfunction, glaucoma, age-related macular degeneration, diabetic retinopathy, and Alzheimer's disease. Priority was given to original research, systematic reviews, and high-impact publications from 2000 through 2025. However, seminal foundational works were included regardless of publication date. Studies were selected based on relevance to glial activation, mitochondrial dysfunction, reactive oxygen and nitrogen species, and disease-specific neuronal outcomes. Across all four diseases, persistent microglial and M\u00fcller glial activation, mitochondrial electron transport chain dysfunction, and excess reactive oxygen species (ROS) and reactive nitrogen species (RNS) production form a self-amplifying feed-forward loop that accelerates neuronal injury. In glaucoma, these mechanisms drive intraocular pressure-independent retinal ganglion cell loss. In AMD and DR, lipid dysregulation, complement activation, and chronic hyperglycemia sustain oxidative-inflammatory injury to the retinal pigment epithelium, photoreceptors, and neurovasculature. In AD, retinal amyloid deposition and oxidative stress mirror cortical pathology, positioning the retina as a noninvasive biomarker site. Neuroinflammation and oxidative stress constitute unifying upstream mechanisms across major vision-threatening neurodegenerative diseases. Combination therapeutic strategies that simultaneously modulate glial activation and restore redox homeostasis may offer superior neuroprotective efficacy compared to approaches targeting isolated downstream mediators.\n\nID: 41897380\nTitle: Mitochondrial ROS in Retinal Neurodegeneration: Thresholds, Quality Control Failure, and Precision Therapeutic Windows.\nAbstract: Mitochondrial reactive oxygen species (mtROS) play a dual role in retinal physiology, acting as essential redox signalling mediators under homeostatic conditions but driving oxidative damage and neurodegeneration once regulatory thresholds are exceeded. Owing to the exceptionally high energetic demands of retinal neurons and supporting cells, even subtle perturbations in mitochondrial redox balance can precipitate progressive retinal dysfunction. Increasing evidence indicates that retinal neurodegenerative diseases, including glaucoma, diabetic retinopathy (DR), age-related macular degeneration (AMD), and inherited optic neuropathies, are characterised not by uniform oxidative stress, but by disease- and stage-specific mtROS signatures shaped by mitochondrial quality control capacity. This review synthesises current insights into the sources, regulation, and signalling functions of mtROS in the retina, with particular emphasis on threshold-dependent redox transitions, reverse electron transport, and the progressive failure of mitochondrial quality control mechanisms, including mitophagy, mitochondrial dynamics, and redox-responsive transcriptional networks. The limitations of non-selective antioxidant strategies are critically examined, highlighting why indiscriminate ROS suppression has yielded limited clinical benefit. In contrast, emerging therapeutic approaches aimed at recalibrating mitochondrial redox homeostasis, rather than abolishing physiological signalling, are discussed in the context of disease stage, metabolic state, and mitochondrial competence. By integrating redox biology with mitochondrial quality control and precision medicine concepts, this review proposes a unifying framework in which retinal neurodegeneration is governed by regulated mtROS signalling and the progressive exhaustion of mitochondrial resilience. This model defines critical therapeutic windows for mitochondria-targeted intervention and provides a framework for biomarker-guided patient stratification.\n\nID: 41890033\nTitle: A FZD4/LRP5 agonist restores pericyte coverage and vascular integrity by increasing PDGFB signaling.\nAbstract: Pericytes, specialized mural cells of capillaries, fulfill crucial physiological functions including promoting endothelial barrier function and regulating angiogenesis. Pericyte loss or dysfunction represents a central pathological feature in diabetic retinopathy (DR) and is increasingly recognized in neurodegenerative diseases as well as in poor stroke outcomes, underscoring an urgent need for therapies that restore pericyte function or promote their regeneration. Here, we utilized a Frizzled4 (FZD4) and Low-Density Lipoprotein Receptor-Related Protein 5 (LRP5) agonist antibody (F4L5.13) to investigate the functional consequences of mimicking \u03b2-catenin-dependent signaling in CNS endothelial cells (ECs), which is physiologically induced by Norrin or WNT7A/B. In platelet-derived growth factor subunit B (Pdgfb) EC-specific knockout (ECKO) mice, a model of severe developmental pericyte deficiency with secondary blood-retina barrier (BRB) defects and hemorrhages, F4L5.13 significantly promoted retinal pericyte/mural cell proliferation and coverage, improved BRB function, reduced hemorrhages, and normalized vascular morphology. F4L5.13 restored Pdgfb mRNA expression levels from non-recombined cells in Pdgfb ECKO retinas. These findings highlight interactions of \u03b2-catenin-dependent signaling and PDGFB production, identify a key pharmacodynamic action of F4L5.13 distinct from anti-VEGF therapies, and suggest that FZD4/LRP5 agonists may have uses as a regenerative pharmacology approach that promotes pericyte coverage in the neurovascular unit.\n\nID: 41814099\nTitle: VEGF and Neurotrophins Interaction in the Retinal Neurovascular Unit Homeostasis: A Target for Ocular Disease Treatment and Management.\nAbstract: Emerging evidence underscores the central role of the retinal neurovascular unit (RNVU) in the pathogenesis of major retinal disorders, including diabetic retinopathy, age-related macular degeneration, and glaucoma. Traditionally considered as primarily vascular diseases, these conditions are now increasingly recognized to involve early neurodegenerative processes that may precede vascular dysfunction. Although anti-VEGF therapies have revolutionized the treatment of neovascular retinal diseases, long-term VEGF inhibition has been associated with adverse effects, including retinal atrophy and diminished neuroprotection, underscoring the need for more targeted strategies. Recent studies have highlighted the differential roles of VEGF-A splice isoforms, particularly the pro-angiogenic VEGF-Axxxa and the anti-angiogenic VEGF-Axxxb, in maintaining RNVU homeostasis and contributing to disease progression. In parallel, neurotrophins such as nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) have demonstrated the ability to exert neuroprotective, anti-inflammatory, and vasomodulatory effects, partly through modulation of VEGF-A signaling. Notably, we have recently demonstrated that NGF modulates VEGF-A isoform expression and VEGFR-2 levels in diabetic retinas, further supporting the hypothesis of a functional cross-talk between neurotrophins and angiogenic pathways. Based on this evidence, a new model is proposed, in which NGF and BDNF interact bidirectionally with VEGF-A to preserve RNVU integrity. This integrated therapeutic perspective, combining neurotrophic support with selective modulation of VEGF-A isoforms, may enhance treatment efficacy, reduce long-term side effects, and minimize the burden of care in chronic retinal neurodegenerative diseases.\n\nID: 41727276\nTitle: Prophylactic self-assembled nucleic acid hydrogel targeting retinal ganglion cell cuproptosis and microglial neuroinflammation for retinal ischemia-reperfusion injury.\nAbstract: Retinal ischemia-reperfusion (RIR) injury constitutes a common pathological pathway in glaucoma, diabetic retinopathy, and other neurodegenerative diseases, frequently leading to irreversible neuronal loss. This study identifies concurrent FDX1-dependent retinal ganglion cell (RGC) cuproptosis and MyD88-mediated microglial inflammation as key drivers of retinal neurodegeneration in RIR. To address this, we developed SAH-CIM, a self-assembled nucleic acid hydrogel for sustained co-delivery of siFdx1 and siMyd88. SAH-CIM effectively suppressed RGC cuproptosis via FDX1 knockdown and reduced pro-inflammatory cytokines by inhibiting the MyD88/TRAF6/NF-\u03baB pathway. In murine RIR models, prophylactic SAH-CIM administration preserved 25.3% more retinal ganglion cells than free siRNA controls, with structural integrity confirmed by histological analysis and optical coherence tomography. Functional recovery was evidenced by electroretinography and visual cliff tests, with SAH-CIM treated mice showing 36.6% reduced time on the cliff side. Crucially, the dual-targeting design demonstrated significantly superior therapeutic efficacy over single-target approaches. The highly biocompatible and self-assembled SAH-CIM presents a promising prophylactic resolution for RIR-related diseases with broad translational potential.\n\nID: 41663366\nTitle: Extraocular delivery of bioswitchable tri-miR-22-loaded tetrahedral DNA nanostructures for intraocular neovascular and neurodegenerative repair.\nAbstract: Ocular neovascular and neurodegenerative diseases, such as diabetic retinopathy and age-related macular degeneration, are characterized by abnormal angiogenesis, vascular leakage, and progressive retinal neurodegeneration, ultimately leading to irreversible vision loss. Here, we present a tetrahedral framework DNA-based bioswitchable Tri-miR-22 mimic delivery system (BiRDS), which is specifically engineered for extraocular administration. In vitro, BiRDS can penetrate the cell membrane within 24\u2009h and accumulate extensively in the cytoplasm. Through transscleral-choroidal-retinal penetration, BiRDS achieves robust delivery to the choroid and retina within 18\u2009h without the need for intravitreal injection in mice. The BiRDS can effectively inhibit the proliferation, tube formation and migration abilities of human umbilical vein endothelial cells. In murine models of choroidal neovascularization and oxygen-induced retinopathy, BiRDS not only suppresses retinal pathological neovascularization with efficacy comparable to that of current anti-VEGF agents, but also possesses unique effects that current agents lack, such as improved retinal perfusion and preserved neuronal integrity, thereby contributing to the protection of visual function. Furthermore, transcriptomic profiling and molecular validation revealed that BiRDS exerts its therapeutic efficacy by inhibiting the Wnt/\u03b2-catenin pathway, a key driver of mediating the aforementioned pathological processes. This study highlights BiRDS as a next-generation RNA nanotherapy with broad clinical potential, offering site specific, multitargeted modulation via a minimally invasive and patient-friendly route.\n\nID: 41563466\nTitle: [Liquid biopsy proteomics in ophthalmology : A\u00a0clinical and scientific perspective].\nAbstract: For many patients with age-related macular degeneration, diabetic retinopathy and other partially monogenetic retinal diseases as well as for tumors of the eye that are relatively rare but are usually associated with profound consequences for affected patients, there is still no effective treatment available. Metastatic melanoma, for example, remains poorly predictable with respect to disease progression, response to treatment and outcome. This illustrates the urgent need for a\u00a0deeper molecular understanding of the disease with the goal to develop novel therapeutic strategies. Liquid biopsies of the aqueous humor represent a\u00a0promising possibility for molecular analyses in the eyes of patients. A\u00a0clinical and scientific perspective with respect to potential fields of applications of liquid biopsy proteomics in ophthalmology is presented. A systematic literature search was carried out in PubMed and the personal experiences of the authors are presented. Aqueous humor proteomics offer a\u00a0plethora of potential applications in ophthalmology and could become a\u00a0key factor in personalized ophthalmology. Potential areas of application include the selection of treatment based on the activated biological signalling pathways, the selection of patients for clinical trials as well as the diagnostics, prognosis estimation and monitoring of the response to treatment. In addition, it can be a\u00a0valuable component of multimodal diagnostics and enable insights into neurodegenerative diseases, such as Alzheimer's or Parkinson's disease. HINTERGRUND: F\u00fcr viele Patienten mit altersabh\u00e4ngiger Makuladegeneration, diabetischer Retinopathie und anderen teils monogenetischen Netzhauterkrankungen wie auch f\u00fcr Tumorerkrankungen des Auges, die zwar relativ selten sind, aber in der Regel mit tiefgreifenden Konsequenzen f\u00fcr die betroffenen Patienten einhergehen, steht weiterhin keine wirksame Therapie zur Verf\u00fcgung.

We previously used a chronic low light (CLL) exposure to model slow photoreceptor degeneration in adult zebrafish. Here, we investigate transcriptional, morphological, and functional responses of microglia in the CLL model. Microglia-specific gene expression analysis was mined from our previously reported 3' RNA-seq data performed at 8 time points during 28 days of CLL exposure. Morphological changes were performed on retinas collected at various time points using immunohistochemistry. Microglial inhibition was accomplished pharmacologically with dexamethasone and genetically using the irf8-/- mutant fish. Finally, we returned the CLL-treated fish to normal light/dark conditions to test whether photoreceptors could recover in the context of chronic stress. CLL induced dynamic, time-dependent upregulation of microglia-specific genes consistent with pro-inflammatory and pro-resolving function. Dexamethasone treatment reduced microglial numbers and exacerbated rod and cone outer segment damage, whereas irf8-/- mutants exhibited partial protection against photoreceptor damage. Notably, despite prolonged stress and damage during the CLL exposure, photoreceptor outer segments returned to near-baseline morphology after 28 days of normal light/dark recovery conditions. Overall, these findings suggest that microglial function in chronic retinal injury is context-dependent as pharmacological and genetic methods of inhibition produced contrasting outcomes depending upon microglial polarization.\n\nID: 41468784\nTitle: Neuropeptide Y at the crossroads of neurodegeneration: Mechanistic insights and emerging therapeutic strategies.\nAbstract: Neuropeptide Y (NPY), a widely distributed and highly conserved neuropeptide, plays a central role in the regulation of diverse physiological processes, including stress responses, energy homeostasis, vascular tone, and immune modulation, via activation of its receptor subtypes. Beyond its physiological roles, the dysregulation of NPY expression has been documented in several neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Machado-Joseph disease, and retinal disorders such as diabetic retinopathy and glaucoma. These alterations in NPY levels and receptor activity highlight its potential not only as a biomarker for disease progression but also as a promising therapeutic target. Previous evidence revealed that NPY exerts neuroprotection by alleviating excitotoxicity, oxidative stress, mitochondrial dysfunction, and neuroinflammation while concurrently facilitating neurogenesis, synaptic plasticity, and cellular resilience. NPY activates receptor-mediated intracellular signaling cascades like PI3K/Akt, MAPK/ERK, and p38K, that control cellular survival, proteostasis, and inflammation and thereby influence disease trajectories. Understanding NPY operation with these mechanisms can unveil new avenues for targeted therapy. Current insights into the complex roles of NPY in neurodegeneration are discussed in this review, and their implications in diagnostic and treatment strategies are addressed.\n\nID: 41169217\nTitle: Retinal proteomics in neurodegeneration: Insights into ocular and brain disorders.\nAbstract: Dysregulated proteome in the retina represents a promising avenue for discovering novel therapeutic targets and noninvasive diagnostic biomarkers for neurodegenerative diseases with ocular manifestations. Advanced mass spectrometry-based proteomics techniques have shown considerable potential in investigating the retinal proteome in diseases such as glaucoma, age-related macular degeneration, diabetic retinopathy, retinitis pigmentosa, as well as Alzheimer's disease, amyotrophic lateral sclerosis, and Parkinson's disease. Recent proteomics innovations are overcoming challenges such as limited sample size and protein coverage that previously hindered comprehensive retinal proteome analysis. Notably, the incorporation of artificial intelligence-driven computational pipelines, including Graphics Processing Unit-accelerated deep learning architectures, has markedly enhanced the precision and effectiveness of retinal proteomics. These advances facilitate high-resolution identification of novel protein signatures within large-scale multi-omics datasets. Furthermore, the integration of advanced artificial intelligence with state-of-the-art big data infrastructures supports the early detection of biomarkers and therapeutic targets in neurodegenerative diseases with ocular involvement, offering unprecedented disease specificity and sensitivity. In addition to these computational strides, emerging complementary and alternative technologies continue to provide valuable tools for retinal analysis, expanding the potential for identifying biomarker and therapeutic targets in both ophthalmic and neurodegenerative disorders. This review summarizes recent advancements in retinal proteomics, with a particular focus on neurodegenerative and ocular diseases.\n\nID: 41158172\nTitle: Integrating plasma proteomics and genome-wide association data to identify therapeutic targets for retinal neurodegenerative diseases in Europeans.\nAbstract: To employ proteome-wide Mendelian randomization (MR) to explore novel protein and drug targets for retinal neurodegenerative diseases (RND) in individuals of European ancestry. This study used summary data-based MR to analyze the correlation between plasma protein levels and three RND, with protein data derived from two independent large-scale proteomics datasets. Potential drug targets were identified using Bayesian colocalization, followed by MR analysis, sensitivity testing, and external validation. Drug prediction and molecular docking were conducted to evaluate the druggability of the target proteins. The study identified six promising protein targets, each successfully replicated at least twice. The results included three proteins related to diabetic retinopathy (ICAM1, GCKR, WARS), two proteins related to age-related macular degeneration (WARS, BRD2), and two proteins related to glaucoma (SVEP1, NPTXR). Additionally, drug prediction and molecular docking indicated that five drugs (fenofibrate, trofinetide, ticagrelor, lifitegrast, acetaminophen) effectively bound to the target proteins. This study identified six potential protein targets for RND and five existing drugs with therapeutic potential. By integrating plasma proteomics with genetic data, it provides a cost-effective framework for drug discovery.\n\nID: 41010507\nTitle: Genetic Susceptibility and Genetic Variant-Diet Interactions in Diabetic Retinopathy: A Cross-Sectional Case-Control Study.\nAbstract: Background/Objectives: Diabetic retinopathy is a leading cause of blindness in diabetic patients, with disease susceptibility influenced by both genetic and environmental factors. This study aimed to identify novel genetic variants associated with DR and evaluate interactions between polygenic risk scores (PRS) and lifestyle factors in a Korean diabetic cohort. Methods: After excluding subjects with non-diabetic retinopathy eye diseases (n = 2519), we analyzed data from 50,361 non-diabetic controls, 4873 diabetic participants without retinopathy (DM-NR), and 165 with diabetic retinopathy (DM-DR). We conducted genome-wide association studies comparing DM-NR and DM-DR groups, performed generalized multifactor dimensionality reduction (GMDR) analysis for epistatic interactions, developed unweighted PRS models, and examined PRS-lifestyle interactions using two-way analysis of covariance. Results: DM-DR prevalence showed strong associations with metabolic syndrome and its components. Five novel genetic variants were identified: ABCA4_rs17110929, MMP2-AS1_rs2576531, FOXP1_rs557869288, MRPS33_rs1533933, and DRD2_rs4936270. A significant three-way epistatic interaction among the first three variants was discovered through GMDR analysis. High-PRS individuals (scores 5-6) showed a 49-fold higher odds ratio of DM-DR compared to low-PRS individuals (scores 0-2; p < 0.0001). MAGMA analysis revealed enrichment in pathways related to protein degradation, vascular function, and neuronal signaling, with predominant upregulation in brain tissues. Significant PRS \u00d7 lifestyle interactions were identified for fruit intake, coffee consumption, alcohol intake, eating duration, and physical activity, with lifestyle factors modifying genetic risk effects (all p < 0.003). Conclusions: These findings identify novel genetic variants and epistatic interactions in DM-DR pathogenesis, supporting the use of PRS-based risk stratification for intensive monitoring and personalized lifestyle interventions. The discovery of brain tissue-enriched pathways suggests DM-DR shares mechanisms with neurodegenerative diseases, expanding therapeutic targets beyond traditional vascular approaches.\n\nID: 40876568\nTitle: Potential role of endoplasmic reticulum quality control in retinal degenerative diseases.\nAbstract: The endoplasmic reticulum (ER) is the largest organelle in eukaryotic cells, and it plays a crucial role in regulating various biological processes, including protein folding, translation, and structural maturation. Accurate protein modification is essential for maintaining oxidative stress, apoptosis, and cellular senescence in the organism. The regulation of protein homeostasis involves three biological processes: endoplasmic reticulum stress (ERS), endoplasmic reticulum autophagy (ERPA), and endoplasmic reticulum-associated degradation (ERAD). Retinal degenerative disease (RDD) is a blinding eye conditions that cause severe vision loss. Although the pathogenesis of RDD is complex, previous data suggest that ER plays a key role in the development of a variety of eye diseases, such as diabetic retinopathy (DR), glaucoma, age-related macular degeneration (AMD), and axial myopia. Based on this, this paper will review the process of endoplasmic reticulum quality control (ERQC) and summarize the pathological mechanisms of the aforementioned eye diseases from the perspective of ERQC, providing new insights for the treatment of RDD.\n\nID: 40817731\nTitle: Insights from TPPP3 and its family member proteins in neuronal diseases.\nAbstract: Tubulin polymerization-promoting protein family member 3 (TPPP3) is a neuronal-specific protein involved in cytoskeletal stability, axonal maintenance, and neuronal survival. Dysregulation of TPPP3 is implicated in neurodegenerative diseases such as Parkinson's disease and diabetic retinopathy. Unlike TPPP1, which is oligodendrocyte-specific, TPPP3 was reported to primarily promote neuronal regeneration and serve as a therapeutic target for neurodegenerative diseases such as Parkinson's disease and glaucoma. Beyond the nervous system, TPPP3 has been linked to oncogenesis and tissue regeneration, suggesting potential roles in tumor suppression and wound healing. This review summarizes neuronal functions of TPPP3, therapeutic opportunities, and future research directions. Understanding the molecular mechanisms underlying function of TPPP3 could provide valuable insights into its therapeutic applications in neuroprotection.\n\nID: 40802083\nTitle: Unveiling the limitations of OCT-based classification in diabetic epiretinal membranes: a call for integrative vascular and structural assessment with OCT-A.\nAbstract: Govetto's optical coherence tomography (OCT)-based staging system is widely used for idiopathic epiretinal membranes (ERMs), but its applicability to diabetic ERMs remains unclear. Given the distinct microvascular pathology in diabetes, this study evaluated the system's applicability in diabetic ERMs and compared structural and vascular features of diabetic and idiopathic ERMs using OCT and OCT-angiography (OCT-A). This retrospective study included 142 eyes with diabetic ERM, idiopathic ERM, and healthy controls. All subjects underwent comprehensive ophthalmic examination, OCT, and OCT-A imaging. ERMs were staged using Govetto et al.'s classification. Correlations between visual acuity (VA), ERM stage, OCT metrics, and OCT-A parameters were analyzed. The macular vessel density ratio (MVR) was also calculated. Ectopic inner foveal layer (EIFL), microcystoid changes, and retinal layer thicknesses were comparable across stages, with EIFL increasing as stages advanced in both groups. EIFL and outer foveal thickness showed no significant group differences, but EIFL was consistently thinner in diabetic cases. Diabetic ERMs had lower vessel densities (VD) and significantly reduced choriocapillaris flow area. Only in the diabetic group were strong correlations observed between outer retinal layer values and VD, as well as between VA, choriocapillaris flow, retinal thickness, and deep macular VD. Although Govetto's OCT-based classification aligns with structural progression in both ERM types, it does not reflect the vascular alterations seen in diabetic ERMs. These findings suggest that structural staging alone may be insufficient in diabetic cases. Awareness of vascular differences and integration of OCT-A parameters may improve interpretation and guide prognosis in diabetic ERMs.\n\nID: 40777392\nTitle: Intranasal Insulin Mediates Neurodegeneration in Diabetic Retinopathy via Regulation of Inflammatory and Apoptotic Pathways.\nAbstract: Neurodegenerative changes predominate in early stages of diabetic retinopathy but effective therapies are lacking. Insulin treatment decreases neurodegeneration and intranasal insulin has been shown to reach the central nervous system in neurodegenerative diseases like dementia. We tested the hypothesis that intranasal insulin can decrease retinal neurodegeneration using the C57BL/KsJ-db/db transgenic diabetic (db/db) mouse model. Compared to the non-diabetic wildtype mice given intranasal saline, we observed decreased electroretinogram b-wave and oscillatory potential amplitudes in db/db mice treated with intranasal saline but not in the db/db mice treated with 2 units of intranasal insulin daily over 10 weeks. When compared to the non-diabetic intranasal saline control, we also observed decreased outer retinal thickness in the db/db mice given intranasal saline but this effect was attenuated in the db/db mice treated with intranasal insulin. GFAP immunoreactivity and caspase cell count were similarly elevated in the db/db mice treated with intranasal saline but not intranasal insulin. Mean blood glucose measurements increased 30 minutes after both intranasal saline and insulin treatment. Transcriptomic analysis revealed downregulation of inflammatory and apoptotic genes in the retina of db/db mice treated with intranasal insulin when compared to saline. In summary, treatment with intranasal insulin prevents the depression of b-waves and oscillatory potentials, decreases the attenuation of outer retinal thickness, reduces caspase cell count and GFAP immunostaining, and downregulates the transcription of inflammatory and apoptotic genes in the retina of db/db mice without exerting peripheral glucose lowering effects. Taken together, our results suggest that intranasal insulin can reduce neurodegeneration in diabetic retinopathy by improving retinal neuronal function, decreasing reactive gliosis and cell death, and modulating the expression of inflammatory and apoptotic genes.\n\nID: 40767008\nTitle: PANoptosis of Retinal Ganglion Cells.\nAbstract: PANoptosis represents a novel form of programmed cell death regulated and controlled by the PANoptosome. It encompasses the essential features of apoptosis, necroptosis, and pyroptosis and combines elements from each process. PANoptosis contributes to the development of various diseases, including bacterial and viral infections, tumors, inflammatory diseases, and neurodegenerative diseases, which offers insights into the pathological mechanisms of these diseases and potential treatments. Retinal ganglion cells (RGCs) are nerve cells located in the final segment of the retina, which belongs to the central nervous system. The loss of RGCs caused by various diseases cannot be reversed. Consequently, safeguarding RGCs from loss is a crucial goal in the treatment of diseases that cause RGCs death (such as trauma, glaucoma, and diabetic retinopathy). Research on the multiple modes of death of RGCs has made some progress and, recently, PANoptosis has been observed during the death of RGCs in different models. In this article, we first give an overview of PANoptosis and summarize the fundamental mechanisms and crosstalk between apoptosis, necroptosis, and pyroptosis, as well as the characteristics of these three modes of cell death that occur in RGCs. Finally, we discuss the current status of research on PANoptosis in neurons and RGCs to establish a theoretical basis for the mechanism of PANoptosis as a novel target for safeguarding RGCs from loss.\n\nID: 40727724\nTitle: Dopamine Alleviated Diabetic Retinal Neurodegeneration through Protecting Retinal Ganglion Cells from Ferroptosis via the Nrf2/HO\u20111 Signaling Pathway.\nAbstract: Diabetic retinopathy (DR) is a major cause of vision impairment, with diabetic retinal neurodegeneration (DRN) identified as an early pathological feature. Although dopamine (DA) has demonstrated protective effects in various neurodegenerative diseases, its role in DRN is inadequately understood. This study provides evidence that DA can alleviate DRN impairment and elucidates the underlying mechanisms. Diabetes was induced in C57BL/6 mice through a single large dose injection of streptozotocin, and the dopamine precursor l-DOPA was administered via intraperitoneal injection daily for 2 weeks to therapeutically supplement dopamine levels. The results indicated that l-DOPA treatment significantly restored retinal thickness, enhanced the amplitude of oscillatory potentials, and alleviated retinal glial cell activation compared to diabetic mice. In vitro, DA treatment of SH-SY5Y cells under high-glucose stress led to a significant increase in superoxide dismutase activity, with a reduction in malondialdehyde levels, lipid peroxide, and iron ion concentration. Additionally, the expression of GPX4, SLC7A11, ferritin, Nrf2, and HO-1 proteins was upregulated, while the expression of NCOA4 was downregulated. Importantly, the protective effects of DA were significantly attenuated by the Nrf2 inhibitor ML385, confirming the involvement of the Nrf2/HO-1 pathway in DA's protective mechanism. These findings suggest that DA alleviates oxidative stress, reduces ferroptosis, and improves the retinal function in DRN through the activation of the Nrf2/HO-1 pathway, indicating that DA may represent a novel therapeutic strategy for treating DRN.\n\nID: 41102382\nTitle: OPTN protects retinal ganglion cells and ameliorates neuroinflammation in optic neuropathies.\nAbstract: Optineurin (OPTN) is an adaptor protein that plays a crucial role in many cellular pathways, including NF-\u03baB signaling, programmed cell death, and vesicular trafficking. OPTN dysfunction has been implicated in the pathogenesis of several diseases, such as primary open angle glaucoma (POAG), amyotrophic lateral sclerosis (ALS). While mutations of OPTN seem to be predominantly loss-of-function in ALS, only gain-of-function mechanisms have been reported in POAG. Here, we demonstrate that OPTN knockout in the retina contributes to short-term astrogliosis, retinal ganglion cell (RGC) loss and long-term microglial activation. Moreover, OPTN loss of function does not exacerbate RGC death induced by ocular hypertension. Integrated bioinformatics and immunofluorescence analyses reveal that OPTN dysfunction leads to neuropeptide Y (NPY) downregulation and CHOP upregulation. Overexpression of wild-type OPTN in a hypertension glaucoma model prevents the RGC loss and attenuates microglial activation. Together, our findings highlight a neuroprotective role for OPTN as a key neuroimmune modulator.\n\nID: 41088409\nTitle: Modeling neurodegeneration in the retina and strategies for developing pan-neurodegenerative therapies.\nAbstract: Glaucoma Research Foundation's third Catalyst for a Cure team (CFC3) was established in 2019 to uncover new therapies for glaucoma, a leading cause of blindness. In the 2021 meeting \"Solving Neurodegeneration,\" (detailed in Mol Neurodegeneration 17(1), 2022) the team examined the failures of investigational monotherapies, issues with translatability, and other significant challenges faced when working with neurodegenerative disease models. They emphasized the need for novel, humanized models and proposed identifying commonalities across neurodegenerative diseases to support the creation of pan-neurodegenerative disease therapies. Since then, the fourth Catalyst for a Cure team (CFC4) was formed to explore commonalities between glaucoma and other neurodegenerative diseases. This review summarizes outcomes from the 2023 \"Solving Neurodegeneration 2\" meeting, a forum for CFC3 and CFC4 to share updates, problem solve, plan future research collaborations, and identify areas of unmet need or opportunity in glaucoma and the broader field of neurodegenerative disease research. We summarize the recent progress in the field of neurodegenerative disease research and present the newest challenges and opportunities moving forward. While translatability and disease complexity continue to pose major challenges, important progress has been made in identifying neuroprotective targets and understanding neuron-glia-vascular cell interactions. New challenges involve improving our understanding of the disease microenvironment and timeline, identifying the optimal approach(es) to neuronal replacement, and finding the best drug combinations and synergies for neuroprotection. We propose solutions to common research questions, provide prescriptive recommendations for future studies, and detail methodologies, strategies, and approaches for addressing major challenges at the forefront of neurodegenerative disease research. This review is intended to serve as a research framework, offering recommendations and approaches to validating neuroprotective targets, investigating rare cell types, performing cell-specific functional characterizations, leveraging novel adaptations of scRNAseq, and performing single-cell sorting and sequencing across neurodegenerative diseases and disease models. We focus on modeling neurodegeneration using glaucoma and other neurodegenerative pathologies to investigate the temporal and spatial dynamics of neurodegenerative disease pathogenesis, suggesting researchers aim to identify pan-neurodegenerative drug targets and drug combinations leverageable across neurodegenerative diseases.\n\nID: 40702789\nTitle: Synthetic microneurotrophins: Neurotrophin receptors for therapeutics of neurodegenerative diseases.\nAbstract: Neurodegenerative disorders are characterised by the chronic progressive degeneration of specific neuronal subtypes, neuroinflammation, myelin damage and synaptic loss. Despite their growing incidence, advancements in effective treatments remain limited, because of lack of knowledge for the aetiology of the diverse pathophysiology to design systematic therapies. Several studies highlight the role of neurotrophic factors (NTFs) as potential neuroprotective, regenerative therapies for these disorders. Although NTFs hold protective and regenerative potential for chronic neuroinflammatory and neurodegenerative conditions, major hurdles impair their clinical use, such as optimising the dosage of NTFs, minimising the invasiveness of delivery methods, overcoming blood-brain-barrier (BBB) impermeability and managing side effects. In the last two decades our group have synthesised and screened a large chemical library of steroidal analogues of dehydroepiandrosterone (DHEA), an endogenous steroid hormone, for their ability to mimic neurotrophin neuroprotective and neurogenic actions. Interestingly, DHEA was shown to interact with all neurotrophin receptors, acting most probably as an ancestral neurotrophin early in evolution. However, its chronic pharmacological use is questioned by its action as a major precursor of steroidogenesis. This review highlights the findings of numerous preclinical studies on these synthetic, non-toxic, BBB permeable DHEA derivatives, named microneurotrophins (MNTs), deprived of endocrine actions, activators of specific neurotrophin receptors. The multimodal actions of MNTs against neuronal death and activation of microglia, in addition to their beneficial effects in synaptogenesis and neurogenesis, place them as interesting lead molecules in the armamentarium of therapeutics for neurodegeneration.\n\nID: 40698100\nTitle: Ganglion Cell Layer Thickness as a Biomarker for Amyotrophic Lateral Sclerosis Functional Outcome: An OCT study.\nAbstract: This study aims to evaluate various optical coherence tomography (OCT) parameters in patients diagnosed with amyotrophic lateral sclerosis (ALS). Assessment of BCVA was done using Snellen charts, and subjective refraction was done to achieve a BCVA for distance and near. Measurement of intraocular pressure (IOP) was done with Goldman applanation tonometry. Stereoscopic fundus examination was performed using a 90D lens to assess the status of the optic nerve and retina, ruling out any ocular pathology. The patients were then subjected to OCT scanning to measure optic nerve head and macular parameters. Optical coherence tomography was performed using CIRRUS\u2122 HD OCT (500-21822) (version 8.0.0.518) (Carl Zeiss Meditec, Dublin, CA, USA). The analyzed area was centered manually, and the absence of segmentation errors was confirmed for each scan. RE Avg RNFL and LE Avg RNFL showed weak correlations with ALSFRS, indicated by Pearson Correlation coefficients of 0.073 and -0.026, respectively. The p-values (0.637 and 0.86) suggested that these correlations were not statistically significant. RE Avg GCL and LE Avg GCL, on the other hand, exhibited moderate positive correlations with ALSFRS scores, with correlation coefficients of 0.337 (RE) and 0.389 (LE). These correlations were statistically significant, as indicated by p-values of 0.021 and 0.006, respectively, suggesting a substantial association between GCL thickness and ALS functional outcomes. All patients in our study were clinically diagnosed cases of ALS, as per the El Escorial criteria. Age group-wise analysis showed statistically significant thinning overall as well as quadrant-wise RNFL parameters in patients less than 50 years compared to age-matched controls, indicating that the pathological process occurring in larger motor neurons in ALS might also be happening in smaller sensory neurons of the retina, causing thinning, which was not due to age-related process. Although GCIPL thinning was occurring in our cases, though statistically not significant compared to control, the significant positive correlation observed between GCIPL and ALS functional outcome and between RNFL and GCIPL measurements highlighted the fact that though the axonal degeneration in retinal neurons might not be translating to the same extent in ganglion cells in ALS, the subtle thinning of GCIPL correlated strongly with functional disability in patients with ALS, implying better functional scores with higher values of GCIPL parameters. In summary, GCL measurements in both eyes showed a notable relationship with ALSFRS, whereas RNFL did not appear to correlate significantly.\n\nID: 39979261\nTitle: Optineurin-facilitated axonal mitochondria delivery promotes neuroprotection and axon regeneration.\nAbstract: Optineurin (OPTN) mutations are linked to amyotrophic lateral sclerosis (ALS) and normal tension glaucoma (NTG), but a relevant animal model is lacking, and the molecular mechanisms underlying neurodegeneration are unknown. We find that OPTN C-terminus truncation (OPTN\u2206C) causes late-onset neurodegeneration of retinal ganglion cells (RGCs), optic nerve (ON), and spinal cord motor neurons, preceded by a decrease of axonal mitochondria in mice. We discover that OPTN directly interacts with both microtubules and the mitochondrial transport complex TRAK1/KIF5B, stabilizing them for proper anterograde axonal mitochondrial transport, in a C-terminus dependent manner. Furthermore, overexpressing OPTN/TRAK1/KIF5B prevents not only OPTN truncation-induced, but also ocular hypertension-induced neurodegeneration, and promotes robust ON regeneration. Therefore, in addition to generating animal models for NTG and ALS, our results establish OPTN as a facilitator of the microtubule-dependent mitochondrial transport necessary for adequate axonal mitochondria delivery, and its loss as the likely molecular mechanism of neurodegeneration.\n\nID: 39267142\nTitle: TwinF interface inhibitor FP802 prevents retinal ganglion cell loss in a mouse model of amyotrophic lateral sclerosis.\nAbstract: Motor neuron loss is well recognized in amyotrophic lateral sclerosis (ALS), but research on retinal ganglion cells (RGCs) is limited. Ocular symptoms are generally not considered classic ALS symptoms, although RGCs and spinal motor neurons share certain cell pathologies, including hallmark signs of glutamate neurotoxicity, which may be triggered by activation of extrasynaptic NMDA receptors (NMDARs). To explore potential novel strategies to prevent ALS-associated death of RGCs, we utilized inhibition of the TwinF interface, a new pharmacological principle that detoxifies extrasynaptic\u00a0NMDARs by disrupting the NMDAR/TRPM4 death signaling complex. Using the ALS mouse model SOD1G93A, we found that the small molecule TwinF interface inhibitor FP802 prevents the loss of RGCs, improves pattern electroretinogram (pERG) performance, increases the retinal expression of Bdnf,\u00a0and restores the retinal\u00a0expression of the immediate early genes, Inhibin beta A and Npas4. Thus, FP802 not only prevents, as recently described, death of spinal motor neurons in SOD1G93A mice, but it\u00a0also mitigates ALS-associated retinal damage. TwinF interface inhibitors have great potential for alleviating neuro-ophthalmologic symptoms in ALS patients and offer a promising new avenue for therapeutic intervention.\n\nID: 38340011\nTitle: Requirement of a novel gene, drish, in the zebrafish retinal ganglion cell and primary motor axon development.\nAbstract: During neurogenesis, growing axons must navigate through the complex extracellular environment and make correct synaptic connections for the proper functioning of neural circuits. The mechanisms underlying the formation of functional neural networks are still only partially understood. Here we analyzed the role of a novel gene si:ch73-364h19.1/drish in the neural and vascular development of zebrafish embryos. We show that drish mRNA is expressed broadly and dynamically in multiple cell types including neural, glial, retinal progenitor and vascular endothelial cells throughout the early stages of embryonic development. To study Drish function during embryogenesis, we generated drish genetic mutant using CRISPR/Cas9 genome editing. drish loss-of-function mutant larvae displayed defects in early retinal ganglion cell, optic nerve and the retinal inner nuclear layer formation, as well as ectopic motor axon branching. In addition, drish mutant adults exhibited deficient retinal outer nuclear layer and showed defective light response and locomotory behavior. However, vascular patterning and blood circulation were not significantly affected. Together, these data demonstrate important roles of zebrafish drish in the retinal ganglion cell, optic nerve and interneuron development and in spinal motor axon branching.\n\nID: 35428871\nTitle: Optical coherence tomography as retinal imaging biomarker of neuroinflammation/neurodegeneration in systemic disorders in adults and children.\nAbstract: The retina and the optic nerve are considered extensions of the central nervous system (CNS) and thus can serve as the window for evaluation of CNS disorders. Spectral domain optical coherence tomography (OCT) allows for detailed evaluation of the retina and the optic nerve. OCT can non-invasively document changes in single retina layer thickness and structure due to neuronal and retinal glial cells (RGC) modifications in systemic and local inflammatory and neurodegenerative diseases. These can include evaluation of retinal nerve fibre layer and ganglion cell complex, hyper-reflective retinal spots (HRS, sign of activated microglial cells in the retina), subfoveal neuroretinal detachment, disorganization of the inner retinal layers (DRIL), thickness and integrity of the outer retinal layers and choroidal thickness. This review paper will report the most recent data on the use of OCT as a non invasive imaging biomarker for evaluation of the most common systemic neuroinflammatory and neurodegenerative/neurocognitive disorders in the adults and in paediatric population. In the adult population the main focus will be on diabetes mellitus, multiple sclerosis, optic neuromyelitis, neuromyelitis optica spectrum disorders, longitudinal extensive transverse myelitis, Alzheimer and Parkinson diseases, Amyotrophic lateral sclerosis, Huntington's disease and schizophrenia. In the paediatric population, demyelinating diseases, lysosomal storage diseases, Nieman Pick type C disease, hypoxic ischaemic encephalopathy, human immunodeficiency virus, leukodystrophies spinocerebellar ataxia will be addressed. \u6458\u8981: \u89c6\u7f51\u819c\u548c\u89c6\u795e\u7ecf\u662f\u4e2d\u67a2\u795e\u7ecf\u7cfb\u7edf (CNS) \u7684\u5ef6\u7eed, \u56e0\u6b64\u53ef\u4ee5\u4f5c\u4e3a\u8bc4\u4f30CNS\u75be\u75c5\u7684\u7a97\u53e3\u3002\u9891\u57df\u5149\u5b66\u76f8\u5e72\u65ad\u5c42\u626b\u63cf (SD-OCT) \u53ef\u4ee5\u5bf9\u89c6\u7f51\u819c\u548c\u89c6\u795e\u7ecf\u8fdb\u884c\u8be6\u7ec6\u7684\u8bc4\u4f30\u3002OCT\u53ef\u4ee5\u65e0\u521b\u6027\u5730\u8bb0\u5f55\u7cfb\u7edf\u6027\u548c\u5c40\u90e8\u708e\u75c7/\u795e\u7ecf\u9000\u884c\u6027\u75c5\u53d8\u4e2d, \u7531\u4e8e\u795e\u7ecf\u5143\u548c\u89c6\u7f51\u819c\u80f6\u8d28\u7ec6\u80de (RGC) \u6539\u53d8\u5f15\u8d77\u7684\u89c6\u7f51\u819c\u5355\u5c42\u539a\u5ea6\u548c\u7ed3\u6784\u7684\u53d8\u5316\u3002OCT\u7684\u89c2\u5bdf\u7684\u6307\u5f81\u5305\u62ec\u8bc4\u4f30\u89c6\u7f51\u819c\u795e\u7ecf\u7ea4\u7ef4\u5c42\u548c\u795e\u7ecf\u8282\u7ec6\u80de\u590d\u5408\u4f53\u3001\u89c6\u7f51\u819c\u9ad8\u53cd\u5c04\u70b9 (HRS, \u89c6\u7f51\u819c\u4e2d\u5c0f\u80f6\u8d28\u7ec6\u80de\u6fc0\u6d3b\u7684\u5f81\u8c61) \u3001\u4e2d\u5fc3\u51f9\u4e0b\u795e\u7ecf\u89c6\u7f51\u819c\u8131\u79bb\u3001\u89c6\u7f51\u819c\u5185\u5c42\u7ed3\u6784\u7d0a\u4e71 (DRIL) \u3001\u89c6\u7f51\u819c\u5916\u5c42\u7684\u539a\u5ea6\u548c\u5b8c\u6574\u6027\u4ee5\u53ca\u8109\u7edc\u819c\u539a\u5ea6\u3002\u672c\u6587\u5c06\u603b\u7ed3OCT\u4f5c\u4e3a\u65e0\u521b\u6210\u50cf\u751f\u7269\u6807\u5fd7\u7269\u8bc4\u4f30\u6210\u4eba\u548c\u513f\u7ae5\u4e2d\u6700\u5e38\u89c1\u7684\u7cfb\u7edf\u6027\u795e\u7ecf\u708e\u75c7\u548c\u795e\u7ecf\u9000\u884c\u6027\u75c5\u53d8/\u795e\u7ecf\u8ba4\u77e5\u969c\u788d\u7684\u6700\u65b0\u6570\u636e\u3002\u5728\u6210\u4eba\u4e2d, \u6211\u4eec\u6700\u5173\u6ce8\u7684\u75be\u75c5\u4e3a\u7cd6\u5c3f\u75c5\u3001\u591a\u53d1\u6027\u786c\u5316\u75c7\u3001\u89c6\u795e\u7ecf\u810a\u9ad3\u708e\u3001\u89c6\u795e\u7ecf\u810a\u9ad3\u708e\u8c31\u7cfb\u969c\u788d\u3001\u7eb5\u5411\u5e7f\u6cdb\u6a2a\u8d2f\u6027\u810a\u9ad3\u708e\u3001\u963f\u5c14\u8328\u6d77\u9ed8\u75c5\u548c\u5e15\u91d1\u68ee\u75c5\u3001\u808c\u840e\u7f29\u4fa7\u7d22\u786c\u5316\u75c7\u3001\u4ea8\u5ef7\u987f\u75c5\u548c\u7cbe\u795e\u5206\u88c2\u75c7\u3002\u5728\u513f\u7ae5\u4e2d, \u6211\u4eec\u7740\u91cd\u8ba8\u8bba\u7684\u75be\u75c5\u6709\u8131\u9ad3\u9798\u75be\u75c5\u3001\u6eb6\u9176\u4f53\u8d2e\u79ef\u75c5\u3001\u5c3c\u66fc-\u5339\u514b\u75c5\u3001\u7f3a\u6c27\u7f3a\u8840\u6027\u8111\u75c5\u3001\u4eba\u7c7b\u514d\u75ab\u7f3a\u9677\u75c5\u6bd2\u3001\u8111\u767d\u8d28\u8425\u517b\u4e0d\u826f\u810a\u9ad3\u5c0f\u8111\u6027\u5171\u6d4e\u5931\u8c03\u3002.\n\nID: 34023378\nTitle: Human primary retinal cells as an in-vitro model for investigating defective signalling caused by OPTN mutants associated with glaucoma.\nAbstract: Studies carried out on the pathogenesis of glaucoma using murine cell lines and animal models require to be validated in human cells. Therefore, we explored the possibility of using human primary retinal cells (hPRCs) in culture as a model for molecular studies and testing of potential therapeutic drugs. For this purpose, central retinal tissue, obtained from the enucleated eyes of patients with anterior staphyloma, was digested with trypsin and grown in a medium containing supplements (basic fibroblast growth factor and fetal bovine serum). hPRCs at passage 1 and 2, show expression of either GFAP, a glial cell marker, or \u03b2-III tubulin, a retinal ganglion cell (RGC)-specific marker. But at passages 3-5 nearly all of hPRCs express several RGC-specific markers (Brn3 proteins, Thy-1, \u03b2-III tubulin, RBPMS and NeuN) but not GFAP. Expression of these markers indicated that these cells may have functional properties of RGCs. As RGCs are sensitive to glaucoma-associated mutants of OPTN, we analysed the survival of hPRCs upon overexpression of OPTN mutants. Glaucoma-associated mutants, E50K-OPTN and M98K-OPTN, induced significantly higher cell death in hPRCs compared to WT-OPTN, whereas an amyotrophic lateral sclerosis-associated mutant, E478G-OPTN, did not. TBK1 inhibitor Amlexanox protected hPRCs from E50K-OPTN and M98K-OPTN induced cell death. M98K-OPTN induced cell death was suppressed by inhibitors of CaMKK\u03b2 and AMPK in hPRCs as well as in 661W, a mouse cell line that expresses several markers of RGCs and RGC precursor cells. Our results suggest that hPRCs under appropriate culture condition show RGC-like properties. These cells can be used to explore the molecular mechanisms of cell death relevant for glaucoma pathogenesis and for testing of cytoprotective compounds.\n\nID: 33562231\nTitle: Retinal Ganglion Cell Loss and Microglial Activation in a SOD1G93A Mouse Model of Amyotrophic Lateral Sclerosis.\nAbstract: The neurodegenerative disease amyotrophic lateral sclerosis (ALS) affects the spinal cord, brain stem, and cerebral cortex. In this pathology, both neurons and glial cells are affected. However, few studies have analyzed retinal microglia in ALS models. In this study, we quantified the signs of microglial activation and the number of retinal ganglion cells (RGCs) in an SOD1G93A transgenic mouse model at 120 days (advanced stage of the disease) in retinal whole-mounts. For SOD1G93A animals (compared to the wild-type), we found, in microglial cells, (i) a significant increase in the area occupied by each microglial cell in the total area of the retina; (ii) a significant increase in the arbor area in the outer plexiform layer (OPL) inferior sector; (iii) the presence of cells with retracted processes; (iv) areas of cell groupings in some sectors; (v) no significant increase in the number of microglial cells; (vi) the expression of IFN-\u03b3 and IL-1\u03b2; and (vii) the non-expression of IL-10 and arginase-I. For the RGCs, we found a decrease in their number. In conclusion, in the SOD1G93A model (at 120 days), retinal microglial activation occurred, taking a pro-inflammatory phenotype M1, which affected the OPL and inner retinal layers and could be related to RGC loss.\n\nID: 33226405\nTitle: Retinal Spheroids and Axon Pathology Identified in Amyotrophic Lateral Sclerosis.\nAbstract: To determine whether patients with amyotrophic lateral sclerosis (ALS) show retinal axon pathology. Postmortem eyes from 10 patients with ALS were sectioned and compared with 10 age-matched controls. Retinal sections were evaluated with periodic acid Schiff and phosphorylated (P-NF) and nonphosphorylated (NP-NF) forms of neurofilament with SMI 31 and 32 antibodies. Spheroids identified in the retinal nerve fiber layer were counted and their overall density was calculated in central, peripheral, and peripapillary regions. P-NF intensity was quantified. Morphometric features of ALS cases were compared with age-matched controls using the exact Wilcoxon matched-pairs signed-rank test. Distinct periodic acid Schiff-positive round profiles were identified in the retinal nerve fiber layer of patients with ALS and were most commonly observed in the peripapillary and peripheral retina. The density of periodic acid Schiff-positive spheroids was significantly greater in patients with ALS compared with controls (P = 0.027), with increased density in the peripapillary region (P = 0.047). Spheroids positive for P-NF and NP-NF were detected. P-NF-positive spheroid density was significantly increased in patients with ALS (P = 0.004), while the density of NP-NF spheroids did not differ significantly between ALS and control groups (P > 0.05). P-NF immunoreactivity in the retinal nerve fiber layer was significantly greater in patients with ALS than in controls (P = 0.002). Retinal spheroids and axon pathology discovered in patients with ALS, similar to hallmark findings in spinal cord motor neurons, point to disrupted axon transport as a shared pathogenesis. Retinal manifestations detected in ALS suggest a novel biomarker detectable by noninvasive retinal imaging to help to diagnose and monitor ALS disease.\n\nID: 33144094\nTitle: Damaging effects of BMAA on retina neurons and M\u00fcller glial cells.\nAbstract: B-N-methylamino-L-alanine (BMAA), a cyanotoxin produced by most cyanobacteria, has been proposed to cause long term damages leading to neurodegenerative diseases, including Amyotrophic Lateral Sclerosis/Parkinsonism Dementia complex (ALS/PDC) and retinal pathologies. Previous work has shown diverse mechanisms leading to BMAA-induced degeneration; however, the underlying mechanisms of toxicity affecting retina cells are not fully elucidated. We here show that BMAA treatment of rat retina neurons in vitro induced nuclear fragmentation and cell death in both photoreceptors (PHRs) and amacrine neurons, provoking mitochondrial membrane depolarization. Pretreatment with the N-Methyl-D-aspartate (NMDA) receptor antagonist MK-801 prevented BMAA-induced death of amacrine neurons, but not that of PHRs, implying activation of NMDA receptors participated only in amacrine cell death. Noteworthy, BMAA stimulated a selective axonal outgrowth in amacrine neurons, simultaneously promoting growth cone destabilization. BMAA partially decreased the viability of M\u00fcller glial cells (MGC), the main glial cell type in the retina, induced marked alterations in their actin cytoskeleton and impaired their capacity to protect retinal neurons. BMAA also induced cell death and promoted axonal outgrowth in differentiated rat pheochromocytoma (PC12) cells, implying these effects were not limited to amacrine neurons. These results suggest that BMAA is toxic for retina neurons and MGC and point to the involvement of NMDA receptors in amacrine cell death, providing new insight into the mechanisms involved in BMAA neurotoxic effects in the retina.\n\nID: 31390360\nTitle: Calcium-responsive transactivator (CREST) toxicity is rescued by loss of PBP1/ATXN2 function in a novel yeast proteinopathy model and in transgenic flies.\nAbstract: Proteins associated with familial neurodegenerative disease often aggregate in patients' neurons. Several such proteins, e.g. TDP-43, aggregate and are toxic when expressed in yeast. Deletion of the ATXN2 ortholog, PBP1, reduces yeast TDP-43 toxicity, which led to identification of ATXN2 as an amyotrophic lateral sclerosis (ALS) risk factor and therapeutic target. Likewise, new yeast neurodegenerative disease models could facilitate identification of other risk factors and targets. Mutations in SS18L1, encoding the calcium-responsive transactivator (CREST) chromatin-remodeling protein, are associated with ALS. We show that CREST is toxic in yeast and forms nuclear and occasionally cytoplasmic foci that stain with Thioflavin-T, a dye indicative of amyloid-like protein. Like the yeast chromatin-remodeling factor SWI1, CREST inhibits silencing of FLO genes. Toxicity of CREST is enhanced by the [PIN+] prion and reduced by deletion of the HSP104 chaperone required for the propagation of many yeast prions. Likewise, deletion of PBP1 reduced CREST toxicity and aggregation. In accord with the yeast data, we show that the Drosophila ortholog of human ATXN2, dAtx2, is a potent enhancer of CREST toxicity. Downregulation of dAtx2 in flies overexpressing CREST in retinal ganglion cells was sufficient to largely rescue the severe degenerative phenotype induced by human CREST. Overexpression caused considerable co-localization of CREST and PBP1/ATXN2 in cytoplasmic foci in both yeast and mammalian cells. Thus, co-aggregation of CREST and PBP1/ATXN2 may serve as one of the mechanisms of PBP1/ATXN2-mediated toxicity. These results extend the spectrum of ALS associated proteins whose toxicity is regulated by PBP1/ATXN2, suggesting that therapies targeting ATXN2 may be effective for a wide range of neurodegenerative diseases.\n\nID: 30944974\nTitle: Microglial activation in an amyotrophic lateral sclerosis-like model caused by Ranbp2 loss and nucleocytoplasmic transport impairment in retinal ganglion neurons.\nAbstract: Nucleocytoplasmic transport is dysregulated in sporadic and familial amyotrophic lateral sclerosis (ALS) and retinal ganglion neurons (RGNs) are purportedly involved in ALS. The Ran-binding protein 2 (Ranbp2) controls rate-limiting steps of nucleocytoplasmic transport. Mice with Ranbp2 loss in Thy1+-motoneurons develop cardinal ALS-like motor traits, but the impairments in RGNs and the degree of dysfunctional consonance between RGNs and motoneurons caused by Ranbp2 loss are unknown. This will help to understand the role of nucleocytoplasmic transport in the differential vulnerability of neuronal cell types to ALS and to uncover non-motor endophenotypes with pathognomonic signs of ALS. Here, we ascertain Ranbp2's function and endophenotypes in RGNs of an ALS-like mouse model lacking Ranbp2 in motoneurons and RGNs. Thy1+-RGNs lacking Ranbp2 shared with motoneurons the dysregulation of nucleocytoplasmic transport. RGN abnormalities were comprised morphologically by soma hypertrophy and optic nerve axonopathy and physiologically by a delay of the visual pathway's evoked potentials. Whole-transcriptome analysis showed restricted transcriptional changes in optic nerves that were distinct from those found in sciatic nerves. Specifically, the level and nucleocytoplasmic partition of the anti-apoptotic and novel substrate of Ranbp2, Pttg1/securin, were dysregulated. Further, acetyl-CoA carboxylase 1, which modulates de novo synthesis of fatty acids and T-cell immunity, showed the highest up-regulation (35-fold). This effect was reflected by the activation of ramified CD11b+ and CD45+-microglia, increase of F4\\80+-microglia and a shift from pseudopodial/lamellipodial to amoeboidal F4\\80+-microglia intermingled between RGNs of naive mice. Further, there was the intracellular sequestration in RGNs of metalloproteinase-28, which regulates macrophage recruitment and polarization in inflammation. Hence, Ranbp2 genetic insults in RGNs and motoneurons trigger distinct paracrine signaling likely by the dysregulation of nucleocytoplasmic transport of neuronal-type selective substrates. Immune-modulators underpinning RGN-to-microglial signaling are regulated by Ranbp2, and this neuronal-glial system manifests endophenotypes that are likely useful in the prognosis and diagnosis of motoneuron diseases, such as ALS.\n\nID: 30458564\nTitle: [Optical Coherence Tomography in Disorders of the Central Nervous System].\nAbstract: Retinal changes and visual symptoms are present in several inflammatory, degenerative and tumorous disorders of the central nervous system (CNS). Optical coherence tomography (OCT) is a method that can be used in clinical practice to detect and quantify the structural correlates of these visual symptoms in neurological disorders. OCT is a non-invasive imaging technique, based on interferometry, which can create high-resolution images of the retina and measure the thickness and volume of the different retinal layers. The combined ganglion cell- and inner plexiform layer (GCIPL) and the peripapillary retinal nerve fibre layer (pRNFL) are of particular interest in the field of neurological disorders, since they contain the neuronal bodies (ganglion cells) and their axons that form the optic nerve. In acute optic neuritis (ON), initial swelling of the pRNFL can be detected by OCT and this may contribute to the diagnosis and differential diagnosis of ON; moreover, the extent of the GCIPL-thinning within the first 4\u00a0weeks after an acute ON can contribute to the prediction of the long-term visual recovery. However, the role of OCT in the field of multiple sclerosis (MS) is not restricted in patients with ON, since even eyes without an ON-history show mild thinning of the pRNFL and GCIPL. This thinning seems to be associated with neurodegenerative processes in the entire CNS. Several studies showed correlations between these OCT-parameters and a higher risk of clinical deterioration (disability progression), cognitive deficits and disease activity in patients with MS. However, it is often still unclear how these correlations can be useful in the management of the individual patient. In recent years, OCT has been applied to a greater extent to neurodegenerative diseases, such as Parkinson's disease, amyotrophic lateral sclerosis (ALS) and various forms of dementia. However, routine clinical use is still further away than for inflammatory CNS diseases, since the role of OCT in the diagnosis, differential diagnosis and prediction of the clinical course of neurodegenerative diseases is still unclear. This review article offers a summary of the available study results on OCT parameters and their role in inflammatory, degenerative and tumorous diseases of the central nervous system (CNS). Inflammatorische, degenerative und tumor\u00f6se Erkrankungen des zentralen Nervensystems (ZNS) gehen h\u00e4ufig mit Ver\u00e4nderungen am Augenhintergrund und Sehst\u00f6rungen einher.

Insbesondere die pRNFL (peripapill\u00e4re retinale Nervenfaserschicht) und GCIPL (Ganglienzellschicht und innere plexiforme Schicht zusammen) sind in der Neurologie von gro\u00dfem Interesse, da sie Axone und zugeh\u00f6rige Nervenzellen enthalten, die im weiteren Verlauf den Sehnerv bilden. Bei einer akuten Optikusneuritis (ON) kann eine initiale Schwellung der pRNFL zur Diagnose und Differenzialdiagnose der ON und eine Verd\u00fcnnung der GCIPL w\u00e4hrend der ersten 4 Wochen zur Prognose der Visuserholung beitragen. Bei der multiplen Sklerose (MS) ist die Rolle der OCT nicht nur in Zusammenhang mit der ON zu sehen. Auch MS-Augen ohne ON zeigen eine Verd\u00fcnnung der pRNFL und GCIPL, die mit neurodegenerativen Prozessen im gesamten ZNS korreliert. Mehrere Studien haben Korrelationen zwischen diesen OCT-Parametern und dem Risiko f\u00fcr eine klinische Verschlechterung (Behinderungsprogression), kognitive Defizite, aber auch Krankheitsaktivit\u00e4t bei MS gezeigt, wobei es h\u00e4ufig noch unklar ist, wie dieser Zusammenhang in der Behandlung des individuellen Patienten nutzbar gemacht werden kann. OCT ist in den letzten Jahren zunehmend auch bei neurodegenerativen Erkrankungen wie Morbus Parkinson, amyotropher Lateralsklerose und diversen Demenzformen eingesetzt worden. Ein Einsatz in der klinischen Routine ist jedoch noch in deutlich weiterer Ferne als bei entz\u00fcndlichen ZNS-Erkrankungen, da der klinische Stellenwert von OCT f\u00fcr Diagnostik, Differenzialdiagnostik und Pr\u00e4diktion bzw. Verlaufsbeurteilung bislang nicht gekl\u00e4rt ist. Dieser \u00dcbersichtsartikel soll einen \u00dcberblick \u00fcber die aktuelle Studienlage zu OCT-Parametern und deren Bedeutung bei inflammatorischen, degenerativen und tumor\u00f6sen Erkrankungen des zentralen Nervensystems schaffen.\n\nID: 29951055\nTitle: Altered Functions and Interactions of Glaucoma-Associated Mutants of Optineurin.\nAbstract: Optineurin (OPTN) is an adaptor protein that is involved in mediating a variety of cellular processes such as signaling, vesicle trafficking, and autophagy. Certain mutations in OPTN (gene OPTN) are associated with primary open angle glaucoma, a leading cause of irreversible blindness, and amyotrophic lateral sclerosis, a fatal motor neuron disease. Glaucoma-associated mutations of OPTN are mostly missense mutations. OPTN mediates its functions by interacting with various proteins and altered interactions of OPTN mutants with various proteins primarily contribute to functional defects. It interacts with Rab8, myosin VI, Huntigtin, TBC1D17, and transferrin receptor to mediate various membrane vesicle trafficking pathways. It is an autophagy receptor that mediates cargo-selective as well as non-selective autophagy. Glaucoma-associated mutants of OPTN, E50K, and M98K, cause defective vesicle trafficking, autophagy, and signaling that contribute to death of retinal ganglion cells (RGCs). Transgenic mice expressing E50K-OPTN show loss of RGCs and persistent reactive gliosis. TBK1 protein kinase, which mediates E50K-OPTN and M98K-OPTN induced cell death, is emerging as a potential drug target. Autoimmunity has been implicated in glaucoma but involvement of OPTN or its mutants in autoimmnity has not been explored. In this review, we highlight the main functions of OPTN and how glaucoma-associated mutants alter these functions. We also discuss some of the controversies, such as the role of OPTN in signaling to transcription factor NF-\u03baB, interferon signaling, and use of RGC-5 cell line as a cell culture model.\n\nID: 29203899\nTitle: 661W is a retinal ganglion precursor-like cell line in which glaucoma-associated optineurin mutants induce cell death selectively.\nAbstract: A photoreceptor cell line, 661W, derived from a mouse retinal tumor that expresses several markers of cone photoreceptor cells has been described earlier. However, these cells can be differentiated into neuronal cells. Here, we report that this cell line expressed certain markers specific to retinal ganglion cells such as Rbpms, Brn3b (Pou4f2), Brn3c (Pou4f3), Thy1 and \u03b3-synuclein (Sncg), and some other markers of neuronal cells (beta-III tubulin, NeuN and MAP2). These cells also expressed Opn1mw, a cone-specific marker and nestin, a marker for neural precursor cells. Two glaucoma-associated mutants of OPTN, E50K and M98K, but not an amyotrophic lateral sclerosis-associated mutant, E478G, induced cell death selectively in 661W cells. However, in a motor neuron cell line, NSC34, E478G mutant of OPTN but not E50K and M98K induced cell death. We conclude that 661W is a retinal ganglion precursor-like cell line, which shows properties of both retinal ganglion and photoreceptor cells. We suggest that these cells could be utilized for exploring the mechanisms of cell death induction and cytoprotection relevant for glaucoma pathogenesis. RGC-5 cell line which probably arose from 661W cells showed expression of essentially the same markers of retinal ganglion cells and neuronal cells as seen in 661W cells.\n\nID: 29169899\nTitle: Comparison of optical coherence tomography findings and visual field changes in patients with primary open-angle glaucoma and amyotrophic lateral sclerosis.\nAbstract: Recent studies revealing genetic connection of primary open angle glaucoma (POAG) and amyotrophic lateral sclerosis (ALS) have received particular attention. Exploring the evidence for common pathogenesis of these two progressive neurological disorders may assist in understanding the mechanism and searching for new treatment. Retinal nerve fiber layer (RNFL) defect and corresponding visual field (VF) impairment are well known neuropathy signs in glaucoma. In our study, thickness of certain retinal layer in ALS patients was analyzed to detect ganglion cell's soma and axon, and for first time visual field was examined for ALS. The correlation of retinal involvement and ALS progression were also investigated. The results were compared with those of POAG. The study may provide new knowledge for these two neurodegenerative diseases.\n\nID: 42477295\nTitle: Ocular Manifestations of Metabolic Syndrome: A Systemic Vascular Phenotype.\nAbstract: Metabolic syndrome (MetS) is defined by central obesity, insulin resistance, hypertension and dyslipidemia. MetS affects over one-third of US adults. Beyond its cardiovascular burden, MetS has clinically relevant associations with ocular health and may contribute to a systemic vascular and neuro-metabolic phenotype involving the retina, optic nerve, lens, ocular surface and choroid. This narrative review searched PubMed through May 2026 using combinations of free-text and MeSH-based terms related to 'metabolic syndrome', 'insulin resistance', 'obesity', 'hypertension', 'dyslipidemia', 'diabetes', 'diabetic retinopathy', 'diabetic macular edema', 'glaucoma', 'cataract', 'dry eye', 'macular degeneration', 'retinal vascular occlusion' and 'optic neuropathy'. Reference lists of relevant reviews and primary studies were also screened. English-language human, translational, epidemiologic, clinical-trial, systematic-review and meta-analysis articles were prioritized. This was not designed as a systematic review, and formal PRISMA screening, risk-of-bias grading and meta-analysis were not performed. MetS and its components are associated with diabetic retinopathy, diabetic macular edema (DME), non-diabetic retinopathy, primary open-angle glaucoma, cataract, dry eye disease, age-related macular degeneration (AMD), retinal vascular occlusions and non-arteritic anterior ischemic optic neuropathy (NAION). Shared mechanisms include chronic inflammation, oxidative stress, endothelial dysfunction, insulin resistance-driven retinal neurodegeneration, dyslipidemia-related lipotoxicity, hypertension-related microvascular injury and microvascular rarefaction. Management requires both systemic risk-factor optimization and disease-specific ophthalmic therapy, including anti-VEGF therapy, intraocular pressure reduction, laser or surgical procedures when indicated, ocular surface-directed therapy and cataract surgery when visually significant. Ocular complications associated with MetS are common and may be vision-threatening. Risk-based ocular surveillance and metabolic optimization are justified, particularly in patients with diabetes, hypertension, dyslipidemia, visual symptoms or established vascular disease. However, the strength of disease-specific evidence varies: interventional evidence is strongest for diabetic retinopathy risk reduction and glaucoma treatment through intraocular pressure lowering, whereas evidence for AMD, NAION, RVO, cataract and dry eye disease is more frequently observational or indirect.\n\nID: 41517507\nTitle: Evolution of Retinal Morphology Changes in Amyotrophic Lateral Sclerosis.\nAbstract: Background/Objectives: To compare changes in the thickness of retinal layers between patients with amyotrophic lateral sclerosis (ALS) and healthy controls using optical coherence tomography. Amyotrophic lateral sclerosis is a degenerative disease of the upper and lower motoneurons with a rapidly progressive course, but non-motor symptoms such as decreased ocular motility and reduced visual acuity have also been reported. Specific biomarkers or surrogate parameters assessing neurodegeneration in ALS are of interest. Methods: In a retrospective, longitudinal study using optic coherence tomography of the retinal layers, we compared changes in the thickness of the layers between patients with ALS and healthy controls. Correlations to clinical scores, such as the modified ranking scale, were analyzed. Results: In our cohort of patients with early ALS (disease duration 5.15 \u00b1 21.4 months at baseline), we neither observed differences in retinal layer thickness at baseline nor did the thickness changes in any retinal layer differ in comparison to healthy controls at baseline. Moreover, we observed no significant thickness changes over the course of the observational period in our patients with ALS. However, a correlation analysis revealed a negative association of the thickness change rates in the complex of ganglion cell and inner plexiform layer and the inner nuclear layer with a higher modified Rankin scale at follow-up. Conclusions: This study adds to the notion that OCT may not be a suitable tool to monitor atrophy and disease progression in ALS. However, further longitudinal studies with longer follow-up times and larger cohorts are warranted.\n\nID: 41488805\nTitle: Increased transmembrane protein 119 (TMEM119) levels in the cerebrospinal fluid of patients with mild cognitive impairment due to Alzheimer's disease suggest early microglial involvement.\nAbstract: We aimed to evaluate the potential of the microglial marker transmembrane protein 119 (TMEM119) in the cerebrospinal fluid (CSF) as a (differential) diagnostic biomarker for neurodegenerative diseases. Following assay validation, we used enzyme-linked immunosorbent assay to measure CSF TMEM119 in 174 patients from six diagnostic groups: Alzheimer's disease (AD, n\u00a0=\u00a035), amyotrophic lateral sclerosis (ALS, n\u00a0=\u00a033), cerebral microangiopathy (CM, n\u00a0=\u00a025), frontotemporal lobar degeneration (FTLD, n\u00a0=\u00a028), Lewy body diseases (n\u00a0=\u00a021), and non-neurodegenerative controls (n\u00a0=\u00a033). CSF TMEM119 levels were elevated in the AD group compared to the control (p\u00a0=\u00a00.004), CM (p\u00a0=\u00a00.005), and FTLD (p\u00a0=\u00a00.023) groups. Levels were higher in both mild cognitive impairment (MCI-AD) and dementia (ADD) subgroups when compared to controls. For the discrimination of AD from controls, the area under the curve (AUC) was 0.78. Our results indicate that CSF TMEM119 may have potential as a biomarker representing microglial involvement in early and later stages of AD. Elevated levels of TMEM119 were observed in the CSF of patients with AD.Increased CSF TMEM119 was seen in MCI-AD patients compared to controls.Elevated levels in MCI-AD underscore early microglial involvement in AD.In the AD group, an association was found between CSF TMEM119 and CSF total tau.CSF TMEM119 may provide valuable information on neuroinflammation.\n\nID: 41165792\nTitle: [Neurodegeneration and retinal changes-A\u00a0literature overview].\nAbstract: The eyes and the central nervous system (CNS) develop from the same embryonic tissue which explains why retinal changes have been observed in various neurological and neurodegenerative diseases. These changes can be visualized in vivo on a\u00a0cellular and subcellular level using optical coherence tomography (OCT). This article summarizes which retinal changes occur and how these could be used as potential biomarkers of neurodegenerative diseases. The article gives an overview of the literature on the relationship between neurodegeneration, OCT-based retinal characteristics and cognitive functions. A literature search was carried out in PubMed until February 2025. The search terms \"neurodegeneration\", \"dementia\", \"mild cognitive impairment\", \"mild neurocognitive disorder\", \"OCT\", \"OCT angiography (OCT-A)\", \"retinal biomarkers\", \"retinal layer\", \"RNFLT\", and \"GCL\" were used. Relevant publications were reviewed, analyzed and summarized. In OCT\u2011A Alzheimer's disease, frontotemporal dementia, vascular dementia, amyotrophic lateral sclerosis, multiple sclerosis (MS) and Parkinson's disease demonstrate an association with a\u00a0reduced retinal nerve fiber layer (RNFL) and the ganglion cell layer (GCL) thickness as well as an enlarged foveal avascular zone. So far retinal changes could not be specifically assigned to a\u00a0particular form of neurodegenerative disease,; however, they could be meaningful in neuropsychological/radiological examinations and for longitudinal monitoring, as already recommended for MS. Further longitudinal studies are needed to identify and validate retinal biomarkers (patterns). HINTERGRUND: Auge und Zentralnervensystem (ZNS) entwickeln sich aus demselben embryonalen Gewebe, weshalb Ver\u00e4nderungen der Retina bei verschiedenen neurologischen und neurodegenerativen Erkrankungen beobachtet werden. Diese k\u00f6nnen mithilfe der optischen Koh\u00e4renztomographie (OCT) auf zellul\u00e4rer und subzellul\u00e4rer Ebene in vivo dargestellt und vermessen werden. Welche retinalen Ver\u00e4nderungen auftreten, und wie diese als m\u00f6gliche Biomarker neurodegenerativer Erkrankungen zu nutzen w\u00e4ren, wird im vorliegenden Beitrag behandelt. \u00dcberblick \u00fcber die Literatur zur Beziehung zwischen Neurodegeneration, OCT-basierten retinalen Charakteristika und kognitiven Funktionen. In PubMed wurde eine Literaturrecherche bis Februar 2025 durchgef\u00fchrt, wobei die Suchbegriffe \u201eneurodegeneration\u201c, \u201edementia\u201c, \u201emild cognitive impairment\u201c, \u201emild neurocognitive disorder\u201c, \u201eOCT\u201c, \u201eOCT-Angiographie (OCT-A)\u201c, \u201eretinale Biomarker\u201c, \u201eretinale Schichten\u201c, \u201eRNFLT\u201c (\u201eretinal nerve fiber layer thickness\u201c) und \u201eGCL\u201c (\u201eganglion cell layer\u201c) verwendet wurden. Relevante Publikationen wurden gesichtet, analysiert und zusammengefasst. Alzheimer-, vaskul\u00e4re und frontotemporale Demenz sowie amyotrophe Lateralsklerose, multiple Sklerose (MS) und M.\u00a0Parkinson weisen in der OCT\u2011A eine Assoziation mit einer reduzierten RNFL und GCL-Dicke sowie einer vergr\u00f6\u00dferter fovealen avaskul\u00e4ren Zone auf. Bisher konnten retinale Ver\u00e4nderungen nicht spezifisch einer bestimmten neurodegenerativen Erkrankung zugeordnet werden. Im Rahmen von neuropsychologischen/-radiologischen Abkl\u00e4rungen und Verlaufsbeurteilungen k\u00f6nnten sie jedoch sinnvoll sein, wie bereits bei der MS empfohlen. Weitere longitudinale Studien sind erforderlich, um retinale Biomarker(-muster) zu identifizieren und zu validieren.\n\nID: 40680585\nTitle: Commentary on 'Retinal Alterations Induced by Amyotrophic Lateral Scerosis: an Analysis Using Optical Coherence Tomography': Drawing Out the Ramifications.\nAbstract: \n\nID: 40625857\nTitle: A Novel Retinal Nerve Fiber Layer Biomarker of Amyotrophic Lateral Sclerosis (ALS) Identified Using Longitudinal in vivo Ocular Imaging.\nAbstract: Like motor neurons, retinal ganglion cells (RGCs) have long axons and high metabolic demands, making them vulnerable to disruption of axonal transport. Unlike motor neurons, the RGC axons are accessible to high-resolution non-invasive optical imaging in their intraocular portion. A non-invasive in vivo retinal imaging biomarker can be valuable for amyotrophic lateral sclerosis (ALS) diagnosis and monitoring. We aim to assess the presence of inner retinal pathology in a mouse model of ALS and its possible progression with age. Transgenic SOD1G93A mice (n=8, 4M/4F) and age-matched controls (n=8, 4M/4F) underwent in vivo retinal imaging with confocal scanning laser ophthalmoscopy (cSLO) coupled with optical coherence tomography (OCT) at 20\u00a0weeks of age. Another group of SOD1G93A mice (n=20, 6M/14F) and age-matched controls (n=20, 6M/14F) underwent longitudinal in vivo retinal imaging with the same device. Each retinal imaging session included infrared reflectance (IR) and blue reflectance (BR) cSLO coupled with OCT. Hyperreflective puncta located in the retinal nerve fiber layer (RNFL) were counted in a blinded fashion in ALS and control mice. The number of puncta at 20\u00a0weeks of age in ALS mice was compared with controls using Wilcoxon test. The rates of increase of puncta number were analyzed using a Generalized Linear Mixed-Effect Model (GLMM) for genotype, time, and sex. IR-cSLO coupled with OCT revealed hyperreflective puncta located in the RNFL of ALS mice. IR-cSLO fundus imaging at the age of 20\u00a0weeks showed ALS mice had significantly higher number of puncta compared to controls (2.1\u00b12.3 vs 0.5\u00b10.8; (mean\u00b1SD), respectively, p=0.036). GLMM analysis showed both ALS mutation and age were significantly associated with the rate of increase of puncta number (p=0.000232 and p=0.000366, respectively). In addition, female ALS mice had a steeper increase of puncta compared to male ALS mice (0.21\u00b10.04 log number puncta/week vs 0.16\u00b10.04, respectively; p=0.037). Our findings demonstrate distinct inner retinal nerve fiber layer pathology, detected using cSLO coupled with OCT, which worsens over time. These findings support the potential of retinal imaging as a translationally relevant, non-invasive biomarker for ALS diagnosis or disease monitoring in humans.\n\nID: 40560963\nTitle: Analysis of retinal markers and incident amyotrophic lateral sclerosis: An optical coherence tomography-based cohort study.\nAbstract: Biomarkers are widely recognized as crucial breakthroughs in tackling amyotrophic lateral sclerosis (ALS). Among them, retina markers may hold promise due to the close retina-brain connection and non-invasive, portable detection methods. Thus, using optical coherence tomography (OCT), we investigated the link between baseline cell-level retinal features and future ALS risk. Participants from the UK Biobank underwent OCT scans to assess retinal layers, macula, and optic disc parameters. Follow-up commenced two years after the baseline period (2006-2010), during which ALS cases were identified using International Classification of Diseases (ICD) codes from medical and assessment records. Cox proportional hazards models were applied to examine the relationship between retinal markers and incident ALS. Over a median follow-up of 14.11 years, 70 ALS cases occurred among 53,824 participants (incidence 10.58 per 100,000 person-years). Most participants were White (94.6%), 44.8% male, with a median age of 58 years. After adjusting for demographics and comorbidities affecting the retina, a standard deviation (SD) decrease of 15.19 \u00b5m in photoreceptor layer (PRL) thickness was associated with a 19% (95% confidence interval [7, 29]; p\u2009=\u20090.002) increased risk of ALS, while a SD increase of 26.11 \u00b5m in retinal pigment epithelium (RPE) thickness corresponded to a 20% (95% CI [7, 34]; p\u2009=\u20090.002) higher risk. Sensitivity analyses excluding follow-ups of less than 4 and 6 years yielded consistent results. Subgroup analyses showed these findings were more pronounced in smokers. The main limitation of this study is its single time point observational design. A thinner PRL and thicker RPE may precede the clinical diagnosis of ALS, offering potential clues for early diagnosis and insights into the disease's pathogenesis.\n\nID: 40354799\nTitle: Efficacy and safety of low-dose IL-2 as an add-on therapy to riluzole (MIROCALS): a phase 2b, double-blind, randomised, placebo-controlled trial.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a life-threatening disease characterised by progressive loss of motor neurons with few therapeutic options. The MIROCALS study tested the hypothesis that low-dose interleukin-2 (IL-2LD) improves survival and function in ALS. In this randomised, double-blind, placebo-controlled trial, male and female riluzole-naive participants, with either a possible, laboratory-supported probable, probable, or definite ALS diagnosis (revised El Escorial criteria), aged 18-76 years, with symptom duration of 24 months or fewer, and slow vital capacity of 70% or more, underwent a riluzole-only 12-18 week run-in period before randomisation in a 1:1 ratio to either 2 million international units (MIU) IL-2LD or placebo by subcutaneous injection daily for 5 days every 28 days over 18 months. The primary endpoint was survival at 640 days (21 months). Secondary outcomes included safety, ALS Functional Rating Scale-Revised (ALSFRS-R) score, and biomarker measurements including regulatory T-cells (Tregs), cerebrospinal fluid (CSF)-phosphorylated-neurofilament heavy-chain (CSF-pNFH), and plasma and CSF-chemokine ligand 2 (CCL2). The primary endpoint analysis used unadjusted log-rank and Cox's model adjusted analyses using pre-defined prognostic covariates to control for the disease and treatment response heterogeneity. The study was 80% powered to detect a two-fold decrease in the risk of death by the log-rank test in the intention-to-treat (ITT) population, including all randomly allocated participants. MIROCALS is registered with ClinicalTrials.gov (NCT03039673) and is complete. From June 19, 2017, to Oct 16, 2019, 304 participants were screened, of whom 220 (72%) met all criteria for random allocation after the 12-to-18-week run-in period on riluzole. 136 (62%) of participants were male and 84 participants (38%) were female. 25 (11%) of the 220 randomly allocated participants were defined as having possible ALS under El Escorial criteria. At the cutoff date there was no loss to follow-up, and all 220 patients who were randomly allocated were documented as either deceased (90 [41%]) or alive (130 [59%]), so all participants were included in the ITT and safety populations. The primary endpoint unadjusted analysis showed a non-significant 19% decrease in risk of death with IL-2LD (hazard ratio 0\u00b781 [95% CI 0\u00b754-1\u00b722], p=0\u00b733), failing to demonstrate the expected two-fold decrease in risk of death. The analysis of the primary endpoint adjusted on prognostic covariates, all measured at time of random allocation, showed a significant decrease of the risk of death with IL-2LD (0\u00b732 [0\u00b714-0\u00b773], p=0\u00b7007), with a significant treatment by CSF-pNFH interaction (1\u00b70003 [1\u00b70001-1\u00b70005], p=0\u00b7001). IL-2LD was safe, and significantly increased Tregs and decreased plasma-CCL2 at all timepoints. Stratification on CSF-pNFH levels measured at random allocation showed that IL-2LD was associated with a significant 48% decrease in risk of death (0\u00b752 [0\u00b730-0\u00b789], p=0\u00b7016) in the 70% of the population with low (750-3700 pg/mL) CSF-pNFH levels, while in the 21% with high levels (>3700 pg/mL), there was no significant difference (1\u00b737 [0\u00b768-2\u00b775], p=0\u00b738). With this treatment schedule, IL-2LD resulted in a non-significant reduction in mortality in the primary unadjusted analysis. However, the difference between the results of unadjusted and adjusted analyses of the primary endpoint emphasises the importance of controlling for disease heterogeneity in ALS randomised controlled trials. The decrease in risk of death achieved by IL-2LD therapy in the trial population with low CSF-pNFH levels requires further investigation of the potential benefit of this therapy in ALS.

This was a cross-sectional observational study. We evaluated retinal layer thickness in 134 ALS patients and 66 HCs using optical coherence tomography (OCT). Particularly, we focused on the macular region and peripapillary retinal nerve fiber layer (p-RNFL). The examination of retinal layers in ALS patients revealed a significant change in the inner nuclear layer (INL), with a pattern of initial thickening followed by thinning, which correlated with disease stages, most notably in the inner nasal quadrant. Moreover, the p-RNFL in the temporal quadrant was thinner in ALS patients compared to HCs. In addition, ALS patients who developed bulbar symptoms exhibited marginally thinner p-RNFL in the temporal quadrant compared to those without bulbar symptoms. Interestingly, a thinner p-RNFL in the temporal quadrant did not correlate with faster disease progression. This study reveals notable changes in the INL and p-RNFL thickness in ALS patients, highlighting the intricate relationship between retinal changes and ALS progression. Despite these retinal alterations, no correlation with disease progression rate was observed. These findings suggest that while OCT shows potential in monitoring ALS, its role in predicting disease course requires further investigation with long-term longitudinal studies and diverse patient cohorts.\n\nID: 40109357\nTitle: Role of Tau Protein Hyperphosphorylation in Diabetic Retinal Neurodegeneration.\nAbstract: Diabetic retinal neurodegeneration (DRN) is an early manifestation of diabetic retinopathy (DR) characterized by neurodegeneration that precedes microvascular abnormalities in the retina. DRN is characterized by apoptosis of retinal ganglion cells (involves alterations in retinal ganglion cells [RGCs], photoreceptors, amacrine cells and bipolar cells and so on), reactive gliosis, and reduced retinal neuronal function. Tau, a microtubule-associated protein, is a key mediator of neurotoxicity in neurodegenerative diseases, with functions in phosphorylation-dependent microtubule assembly and stabilization, axonal transport, and neurite outgrowth. The hyperphosphorylated tau (p-tau) loses its ability to bind to microtubules and aggregates to form paired helical filaments (PHFs), which further form neurofibrillary tangles (NFTs), leading to abnormal cell scaffolding and cell death. Studies have shown that p-tau can cause degeneration of RGCs in DR, making tau pathology a new pathophysiological model for DR. Here, we review the mechanisms by which p-tau contribute to DRN, including insulin resistance or lack of insulin, mitochondrial damage such as mitophagy impairment, mitochondrial axonal transport defects, mitochondrial bioenergetics dysfunction, and impaired mitochondrial dynamics, Abeta toxicity, and inflammation. Therefore, this article proposes that tau protein hyperphosphorylation plays a crucial role in the pathogenesis of DRN and may serve as a novel therapeutic target for combating DRN.\n\nID: 39799044\nTitle: Loss of Insight in Syndromes Associated with Frontotemporal Lobar Degeneration: Clinical and Imaging Features.\nAbstract: The present study aims to assess the prevalence, associated clinical symptoms, longitudinal changes, and imaging correlates of Loss of Insight (LOI), which is still unexplored in syndromes associated with Frontotemporal Lobar Degeneration (FTLD). Retrospective longitudinal cohort study, from Oct 2009 to Feb 2023. Tertiary Frontotemporal Dementia research clinic. A sample of 712 FTLD patients, 331 of whom had follow-up evaluation. LOI was assessed by interview with the primary caregiver. Univariate and multiple logistic regression and linear mixed models were used to estimate predictors and longitudinal changes over time associated with LOI. Voxel-based morphometry and structural covariance analyses of brain structural MRI images were implemented in Statistical Parametric Mapping. LOI was reported in 45% of patients (321/712, 95%CI = 41-49), with progressively increased prevalence from prodromal to severe dementia stages. LOI was more prevalent in the behavioural variant FTD, in the semantic variant of Primary Progressive Aphasia (svPPA) and FTD with Amyotrophic Lateral Sclerosis than in other phenotypes (all p-values<0.001). LOI severity increased over time only in patients with svPPA (\u03b2 = +0.59, p <0.001) and clustered with other behavioral symptoms (all p-values <0.05). Finally, LOI was significantly associated with greater atrophy in the right medial orbital gyrus (p <0.001 uncorrected). Structural covariance analysis demonstrated loss of negative correlation between right medial orbital gyrus and regions belonging to the Default Mode Network (DMN), such as the left precuneus and the left angular gyrus (p \u22640.05 family-wise error-corrected) in FTLD patients with LOI. A better comprehension of LOI mechanisms could lead to more effective interventions and healthcare policies.\n\nID: 39737769\nTitle: Insights Into Retinal Pathologies in Neurological Disorders: A Focus on Parkinson's Disease, Multiple Sclerosis, Amyotrophic Lateral Sclerosis, and Alzheimer's Disease.\nAbstract: Neurological diseases are central nervous system (CNS) disorders affecting the whole body. Early diagnosis of the diseases is difficult due to the lack of disease-specific tests. Adding new biomarkers external to the CNS facilitates the diagnosis of neurological diseases. In this respect, the retina has a common embryologic origin with the CNS. Retinal imaging technologies including optical coherence tomography (OCT) can be used in the understanding and processual monitoring of neurological diseases. Retinal imaging has been recently recognized as a potential source of biomarkers for neurological diseases, increasing the number of studies in this direction. In this review, the association of retinal abnormalities with Parkinson's disease (PD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), and Alzheimer's disease (AD) is explained. Structural and functional abnormalities in retina as a predictive marker may facilitate early diagnosis of diseases. Although not all retinal abnormalities are predictive of neurologic diseases, changes in the retinal layers including retinal pigment epithelium and plexiform layers should suggest the risk of PD, MS, ALS, and AD.\n\nID: 38351392\nTitle: Review of lipocalin-2-mediated effects in diabetic retinopathy.\nAbstract: Studies have uncovered LCN2 as a marker of inflammation strongly related to obesity, insulin resistance, and abnormal glucose metabolism in humans, and is involved in vascular diseases, inflammatory diseases, and neurological diseases. In recent years, studies have shown that elevated levels of LCN2 have a strong association with diabetic retinopathy (DR), but the pathogenesis is unknown. Here, we reviewed the relevant literature and compiled the pathogenesis associated with LCN2-induced DR. We searched PubMed and Web of Science electronic databases using \"lipocalin-2, diabetic retinopathy, retinal degeneration, diabetic microangiopathies, diabetic neuropathy and inflammation\" as subject terms. In diabetic retinal neuropathy, LCN2 causes impaired retinal photoreceptor function and retinal neurons; in retinal microangiopathy, LCN2 induces apoptosis of retinal vascular endothelial cells and promotes angiogenesis; in retinal inflammation, increased secretion of LCN2 recruits inflammatory cells and induces pro-inflammatory cytokines. Moreover, LCN2 has the potential as a biomarker for DR. Recent studies have shown that retinal damage can be attenuated by silencing LCN2, which may be associated with the inhibition of caspase-1-mediated pyroptosis, and LCN2 may be a new target for the treatment of DR. In conclusion, LCN2, involved in the development of diabetic retinopathy, is a key factor in diabetic retinal microangiopathy, neurodegeneration, and retinal inflammation. LCN2 is likely to be a novel molecular target leading to DR, and a more in-depth study of the pathogenesis of DR caused by LCN2 may provide considerable benefits for clinical research and potential drug development.\n\nID: 37855949\nTitle: Retina Oculomics in Neurodegenerative Disease.\nAbstract: Ophthalmic biomarkers have long played a critical role in diagnosing and managing ocular diseases. Oculomics has emerged as a field that utilizes ocular imaging biomarkers to provide insights into systemic diseases. Advances in diagnostic and imaging technologies including electroretinography, optical coherence tomography (OCT), confocal scanning laser ophthalmoscopy, fluorescence lifetime imaging ophthalmoscopy, and OCT angiography have revolutionized the ability to understand systemic diseases and even detect them earlier than clinical manifestations for earlier intervention. With the advent of increasingly large ophthalmic imaging datasets, machine learning models can be integrated into these ocular imaging biomarkers to provide further insights and prognostic predictions of neurodegenerative disease. In this manuscript, we review the use of ophthalmic imaging to provide insights into neurodegenerative diseases including Alzheimer Disease, Parkinson Disease, Amyotrophic Lateral Sclerosis, and Huntington Disease. We discuss recent advances in ophthalmic technology including eye-tracking technology and integration of artificial intelligence techniques to further provide insights into these neurodegenerative diseases. Ultimately, oculomics opens the opportunity to detect and monitor systemic diseases at a higher acuity. Thus, earlier detection of systemic diseases may allow for timely intervention for improving the quality of life in patients with neurodegenerative disease.\n\nID: 37850093\nTitle: In vivo retinal imaging is associated with cognitive decline, blood-brain barrier disruption and neuroinflammation in type 2 diabetic mice.\nAbstract: Type 2 diabetes (T2D) is associated with chronic inflammation and neurovascular changes that lead to functional impairment and atrophy in neural-derived tissue. A reduction in retinal thickness is an early indicator of diabetic retinopathy (DR), with progressive loss of neuroglia corresponding to DR severity. The brain undergoes similar pathophysiological events as the retina, which contribute to T2D-related cognitive decline. This study explored the relationship between retinal thinning and cognitive decline in the LepR db/db model of T2D. Diabetic db/db and non-diabetic db/+ mice aged 14 and 28 weeks underwent cognitive testing in short and long-term memory domains and in vivo retinal imaging using optical coherence tomography (OCT), followed by plasma metabolic measures and ex vivo quantification of neuroinflammation, oxidative stress and microvascular leakage. At 28 weeks, mice exhibited retinal thinning in the ganglion cell complex and inner nuclear layer, concomitant with diabetic insulin resistance, memory deficits, increased expression of inflammation markers and cerebrovascular leakage. Interestingly, alterations in retinal thickness at both experimental timepoints were correlated with cognitive decline and elevated immune response in the brain and retina. These results suggest that changes in retinal thickness quantified with in vivo OCT imaging may be an indicator of diabetic cognitive dysfunction and neuroinflammation.\n\nID: 37289322\nTitle: Neurodegeneration in the retina of motoneuron diseases: a longitudinal study in amyotrophic lateral sclerosis and Kennedy's disease.\nAbstract: To what extent retinal atrophy in neurodegenerative diseases reflects the severity and/or the chronicity of brain pathology or is a local independent phenomenon remains to be clarified. Moreover, whether retinal atrophy has a clinical (diagnostic and prognostic) value in these diseases remains unclear. To add light on the pathological significance and clinical value of retinal atrophy in patients with amyotrophic lateral sclerosis (ALS) and Kennedy's disease (KD). Thirty-five ALS, thirty-seven KD, and forty-nine age-matched healthy controls (HC) were included in a one-year longitudinal study. Spectrum-domain optical coherence tomography (OCT) was performed at study entry (T0) and after 12\u00a0months (T1). Disease duration and functional rating scale (FRS) for ALS and KD patients were correlated to retinal thicknesses. Compared to HC, peripapillary retinal nerve fiber layer (pRNFL) thickness was significantly thinner in both ALS (p\u2009=\u20090.034) and KD (p\u2009=\u20090.003). pRNFL was thinner in KD compared to ALS, but the difference was not significant. In KD, pRNFL atrophy significantly correlated with both disease severity (r\u2009=\u20090.296, p\u2009=\u20090.035) and disease duration (r\u2009=\u2009-\u20090.308, p\u2009=\u20090.013) while no significant correlation was found in ALS (disease severity: r\u2009=\u20090.147, p\u2009=\u20090.238; disease duration: r\u2009=\u2009-\u20090.093, p\u2009=\u20090.459). During the follow-up, pRNFL thickness remained stable in KD while significantly decreased in ALS (p\u2009=\u20090.043). Our study provides evidence of retinal atrophy in both ALS and KD and suggests that retinal thinning is a primary local phenomenon in motoneuron diseases. The clinical value of pRNFL atrophy in KD is worthy of further investigation.\n\nID: 37271122\nTitle: Quantitatively Evaluating the Relationships between Insulin Resistance and Retinal Neurodegeneration with Optical Coherence Tomography in Early Type 2 Diabetes Mellitus.\nAbstract: The aim of this study was to quantitatively assess retinal neurodegenerative changes with optical coherence tomography (Cirrus HD-OCT) in type 2 diabetes mellitus (T2DM) patients without diabetic retinopathy (DR) and evaluate their relationships with insulin resistance (IR) and associated systemic indicators. 102 T2DM patients without DR and 48 healthy controls were included in this observational cross-sectional study. The OCT parameters of macular retinal thickness (MRT) and ganglion cell-inner plexiform layer (GCIPL) thicknesses were evaluated between diabetic and normal eyes. The receiver operating characteristics (ROC) curve was generated to evaluate the discrimination power of early diabetes. Correlation and multiple regression analysis were performed between ophthalmological parameters and T2DM-related demographic and anthropometric variables, and serum biomarkers and homeostasis model assessment of insulin resistance (HOMA-IR) scores. MRT and GCIPL thicknesses showed significant thinning in patients, especially in inferotemporal area. High body mass index (BMI) correlated with decreased GCIPL thicknesses and elevated intraocular pressure (IOP). A negative correlation between waist-to-hip circumference ratio (WHR) and GCIPL thicknesses was also found. High-density lipoprotein (HDL) and fasting C-peptide (CP0) were associated with GCIPL thickness but only in inferotemporal region (r = 0.20, p = 0.04; r = -0.20, p = 0.05, respectively). Multiple regression analysis showed that increased HOMA-IR scores independently predicted both average (\u03b2 = -0.30, p = 0.05) and inferotemporal (\u03b2 = -0.34, p = 0.03) GCIPL thinning. Retinal thinning in early T2DM was associated with obesity-related metabolic disorders. IR as an independent risk factor for retinal neurodegeneration may increase the risk of developing glaucoma.\n\nID: 37163838\nTitle: Sleep in amyotrophic lateral sclerosis: A systematic review and meta-analysis of polysomnographic findings.\nAbstract: This study explores the polysomnographic differences between amyotrophic lateral sclerosis (ALS) patients and healthy controls. An electronic literature search was conducted in MEDLINE, EMBASE, All EBM databases, Web of Science, and CNKI from inception to Oct 2022. Meta-analyses revealed significant reductions in sleep efficiency, total sleep time, N2%, slow wave sleep percentage, minimum SpO2, and mean SpO2, and increases in wake time after sleep onset and N1%, sleep latency, rapid eye movement sleep latency, time spent with SpO2 < 90%, oxygen desaturation index, and apnea hypopnea index in ALS patients compared with controls. Sensitivity analyses showed that some heterogeneity was explained by excluding patients taking medications impacting sleep, whether studies employed an adaptation night, and the use of different PSG scoring rules. Significant polysomnographic abnormalities are present in ALS. Our findings underscore the need for a comprehensive PSG assessment of sleep changes in ALS patients. When performing PSG examinations in ALS, whether the patients are taking medication impacting sleep and the scoring system used should be considered.\n\nID: 36842953\nTitle: Retinal vessels as a window on amyotrophic lateral sclerosis pathophysiology: A systematic review.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rare fatal motor neuron disease. Although many potential mechanisms have been proposed, the pathophysiology of the disease remains unknown. Currently available treatments can only delay the progression of the disease and prolong life expectancy by a few months. There is still no definitive cure for ALS, and the development of new treatments is limited by a lack of understanding of the underlying biological processes that trigger and promote neurodegeneration. Several scientific results suggest a neurovascular impairment in ALS providing perspectives for the development of new biomarkers and treatments. In this article, we performed a systematic review using PRISMA guidelines including PubMed, EmBase, GoogleScholar, and Web of Science Core Collection to analyze the scientific literature published between 2000 and 2021 discussing the neurocardiovascular involvement and ophthalmologic abnormalities in ALS. In total, 122 articles were included to establish this systematic review. Indeed, microvascular pathology seems to be involved in ALS, affecting all the neurovascular unit components. Retinal changes have also been recently highlighted without significant alteration of the visual pathways. Despite the peripheral location of the retina, it is considered as an extension of the central nervous system (CNS) as it displays similarities to the brain, the inner blood-retinal barrier, and the blood-brain barrier. This suggests that the eye could be considered as a 'window' into the brain in many CNS disorders. Thus, studying ocular manifestations of brain pathologies seems very promising in understanding neurodegenerative disorders, mainly ALS. Optical coherence tomography angiography (OCT-A) could therefore be a powerful approach for exploration of retinal microvascularization allowing to obtain new diagnostic and prognostic biomarkers of ALS.\n\nID: 36766803\nTitle: Kynurenine Pathway in Diabetes Mellitus-Novel Pharmacological Target?\nAbstract: The tryptophan-kynurenine pathway (Trp-KYN) is the major route for tryptophan conversion in the brain and in the periphery. Kynurenines display a wide range of biological actions (which are often contrasting) such as cytotoxic/cytoprotective, oxidant/antioxidant or pro-/anti-inflammatory. The net effect depends on their local concentration, cellular environment, as well as a complex positive and negative feedback loops. The imbalance between beneficial and harmful kynurenines was implicated in the pathogenesis of various neurodegenerative disorders, psychiatric illnesses and metabolic disorders, including diabetes mellitus (DM). Despite available therapies, DM may lead to serious macro- and microvascular complications including cardio- and cerebrovascular disease, peripheral vascular disease, chronic renal disease, diabetic retinopathy, autonomic neuropathy or cognitive impairment. It is well established that low-grade inflammation, which often coincides with DM, can affect the function of KP and, conversely, that kynurenines may modulate the immune response. This review provides a detailed summary of findings concerning the status of the Trp-KYN pathway in DM based on available animal, human and microbiome studies. We highlight the importance of the molecular interplay between the deranged (functionally and qualitatively) conversion of Trp to kynurenines in the development of DM and insulin resistance. The Trp-KYN pathway emerges as a novel target in the search for preventive and therapeutic interventions in DM.\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: 41554422\nTitle: Integrated proteomic profiling of aqueous humor reveals CDC42/RHOA-mediated pathogenic mechanisms in nAMD and PDR.\nAbstract: Neovascular age-related macular degeneration (nAMD) and proliferative diabetic retinopathy (PDR), though clinically distinct, are both sight-threatening ocular disorders driven by pathological neovascularization. However, their shared molecular mechanisms remain poorly characterized. In this study, we performed DIA quantitative proteomic analysis of aqueous humor (AH) from patients with nAMD, PDR, and control. A total of 3186 proteins were identified, in which 877 and 1017 differentially expressed proteins (DEPs) were detected in the nAMD and PDR groups, respectively, compared to control group. Functional enrichment analysis revealed significant involvement of inflammatory and metabolic pathways in both diseases. Notably, the persistent upregulation of cell division cycle 42 (CDC42) and ras homolog family member A (RHOA) in nAMD and PDR, combined with their established role in cytoskeletal remodeling, suggests their significant involvement in pathological angiogenesis. These findings offer novel perspectives on shared pathogenic pathways in neovascular ocular disorders and suggest potential therapeutic targets for further investigation.\n\nID: 41373784\nTitle: From Synaptic Plasticity to Neurotoxicity: Endocannabinoid Influence on Addiction and Neurodegeneration.\nAbstract: The endocannabinoid system (eCBS) is a versatile neuromodulatory network that orchestrates synaptic plasticity, reward processing, and neuronal homeostasis. Increasing evidence implicates eCBS dysregulation in both addiction and neurodegenerative (ND) disorders, suggesting overlapping molecular and cellular mechanisms underlying these conditions. This review synthesizes recent advances in understanding how eCBS components-cannabinoid receptors (CB1 and CB2), endogenous ligands (anandamide and 2-arachidonoylglycerol), and their metabolic enzymes-modulate dopaminergic and glutamatergic signaling within reward and reinforcement circuits. Chronic exposure to drugs of abuse, including alcohol, opioids, cocaine, and methamphetamine, perturbs eCBS homeostasis, promoting oxidative stress, neuroinflammation, excitotoxicity, mitochondrial dysfunction, and protein aggregation-pathological features common to Alzheimer's, Parkinson's, Huntington's, and amyotrophic lateral sclerosis. These overlapping mechanisms disrupt neuronal integrity and contribute to progressive neurotoxicity, highlighting shared pathogenic pathways between addiction and neurodegeneration. Despite these advances, critical gaps remain in delineating how substance-induced eCBS alterations precipitate neurodegenerative cascades. Addressing these gaps will be essential for harnessing the eCBS as a therapeutic target to mitigate addiction-driven neurotoxicity and age-related cognitive decline.\n\nID: 39390534\nTitle: Is longer axial length protective of vision-threatening diabetic retinopathy across different ages? A multicenter cohort of 736 patients.\nAbstract: Vision-threatening diabetic retinopathy (VTDR) included severe non-proliferative diabetic retinopathy (NPDR), proliferative diabetic retinopathy (PDR) and clinically significant diabetic macular edema (DME). To compare the axial length (AL) and assess its influence on VTDR across different ages. A retrospective cohort study. Medical chart review was performed in 736 consecutive patients with VTDR. The patients were divided into young (\u2264\u200945\u00a0years) and elderly group (>\u200945\u00a0years) based on their age at the diagnosis of VTDR. After at least one year of standardized treatments, all eligible patients were followed up. The main outcome measures included the presence of tractional retinal detachment (TRD) involving foveal, final best-corrected visual acuity (BCVA), the development of neovascular glaucoma (NVG), and recurrent vitreous hemorrhage (VH) post-vitrectomy. ALs were compared between two age groups. The impact of AL on clinical outcomes was determined by logistic analyses after controlling for systemic parameters. The study included 144 patients\u2009\u2264\u200945\u00a0years and 592 patients\u2009>\u200945\u00a0years. Young patients had significantly longer AL than elderly participants (23.9\u00a0mm vs 23.0\u00a0mm, p\u2009<\u20090.001). Over a median follow-up of 25.9\u00a0months, a larger proportion of young patients developed TRD (34.7% vs 16.2%, p\u2009<\u20090.001) and recurrent VH (18.6% vs 10.3%, p\u2009=\u20090.040) than elderly patients. In elderly group, longer AL is an independent protective factor in preventing TRD (odds ratio [OR], 0.5; 95% confidence interval [CI], 0.4-0.7; P\u2009<\u20090.001). However, this beneficial effect was not observed in young patients. Young patients with VTDR exhibited significantly longer AL but more aggressive clinical signs with compromised prognosis. In elderly group, a longer AL independently reduced the risk of TRD, while this protective effect did not exist for young patients.\n\nID: 32351353\nTitle: Rhodopsin: A Potential Biomarker for Neurodegenerative Diseases.\nAbstract: Retinal alterations have recently been associated with numerous neurodegenerative diseases. Rhodopsin is a G-protein coupled receptor found in the rod cells of the retina. As a biomarker associated with retinal thinning and degeneration, it bears potential in the early detection and monitoring of several neurodegenerative diseases. In this review article, we summarize the findings of correlations between rhodopsin and several neurodegenerative disorders as well as the potential of a novel technique, cSLO, in the quantification of rhodopsin.\n\nID: 31822699\nTitle: SMN complex member Gemin3 self-interacts and has a functional relationship with ALS-linked proteins TDP-43, FUS and Sod1.\nAbstract: The predominant motor neuron disease in infants and adults is spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS), respectively. SMA is caused by insufficient levels of the Survival Motor Neuron (SMN) protein, which operates as part of the multiprotein SMN complex that includes the DEAD-box RNA helicase Gemin3/DDX20/DP103. C9orf72, SOD1, TDP-43 and FUS are ranked as the four major genes causing familial ALS. Accumulating evidence has revealed a surprising molecular overlap between SMA and ALS. Here, we ask the question of whether Drosophila can also be exploited to study shared pathogenic pathways. Focusing on motor behaviour, muscle mass and survival, we show that disruption of either TBPH/TDP-43 or Caz/FUS enhance defects associated with Gemin3 loss-of-function. Gemin3-associated neuromuscular junction overgrowth was however suppressed. Sod1 depletion had a modifying effect in late adulthood. We also show that Gemin3 self-interacts and Gem3\u0394N, a helicase domain deletion mutant, retains the ability to interact with its wild-type counterpart. Importantly, mutant:wild-type dimers are favoured more than wild-type:wild-type dimers. In addition to reinforcing the link between SMA and ALS, further exploration of mechanistic overlaps is now possible in a genetically tractable model organism. Notably, Gemin3 can be elevated to a candidate for modifying motor neuron degeneration.\n\nID: 28945811\nTitle: Retinal thinning in amyotrophic lateral sclerosis patients without ophthalmic disease.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal, rapidly progressive neurodegenerative disease that primarily affects motor neurons. Recently, three causative genes have been implicated in both ALS and glaucoma. However, it is still uncertain whether patients with ALS have neurodegeneration in their retinas. If so, retinal thickness measurements might be a useful biomarker for ALS progression. Previous work in this area has been inconclusive, as it has not taken into account the effect of ophthalmic diseases on retinal thinning. To determine whether there are differences in retinal neurons in ALS patients utilizing spectral-domain optical coherence tomography (SD-OCT). We tested the hypothesis that ALS patients exhibit retinal neurodegeneration that is not associated with ophthalmic diseases. Observational, comparative, cross-sectional study performed on patients recruited from the Duke University Medical Center ALS clinic. Patients underwent a comprehensive ophthalmologic examination to rule out ocular pathology. 21 patients met inclusion criteria. Two eyes with ocular pathology were excluded, leading to a total of 40 eyes of 21 patients included in the study. Retinal neurodegeneration was assessed by retinal nerve fiber layer (RNFL) thickness measurement using SD-OCT (Spectralis; Heidelberg Engineering). ALS disease severity, determined through the ALS Functional Rating Scale (ALSFRS-R); mean and six sector RNFL thickness values compared to age-adjusted values in the normative database provided by Heidelberg Engineering; RNFL thickness correlation with ALSFRS-R, ALSFRS-R progression rate, forced vital capacity (FVC), and visual acuity. ALSFRS-R mean score was 30+/-10. Mean RNFL thickness in ALS patients was 88.95 +/- 10.8 microns, significantly thinner than values in the normative database (95.81 +/- 0.8). These RNFL thickness values did not demonstrate correlation to ALSFRS-R score, ALSFRS-R progression rate, FVC, intraocular pressure, or visual acuity. Using SD-OCT, our study shows that ALS patients without ocular pathology exhibit thinned retinal layers. Future studies are warranted to clarify the clinical relationship between retinal thinning and motor neuron loss in ALS.\n\nID: 27939241\nTitle: The anti-ALS drug riluzole attenuates pericyte loss in the diabetic retinopathy of streptozotocin-treated mice.\nAbstract: Loss of pericytes, considered an early hallmark of diabetic retinopathy, is thought to involve abnormal activation of protein kinase C (PKC). We previously showed that the anti-amyotrophic lateral sclerosis (ALS) drug riluzole functions as a PKC inhibitor. Here, we examined the effects of riluzole on pathological changes in diabetic retinopathy. Pathological endpoints examined in vivo included the number of pericytes and integrity of retinal vessels in streptozotocin (STZ)-induced diabetic mice. In addition, PKC activation and the induction of monocyte chemotactic protein (MCP1) were assessed in diabetic mice and in human retinal pericytes exposed to advanced glycation end product (AGE) or modified low-density lipoprotein (mLDL). The diameter of retinal vessels and the number of pericytes were severely reduced, and the levels of MCP1 and PKC were increased in STZ-induced diabetic mice. Administration of riluzole reversed all of these changes. Furthermore, the increased expression of MCP1 in AGE- or mLDL-treated cultured retinal pericytes was inhibited by treatment with riluzole or the PKC inhibitor GF109203X. In silico modeling showed that riluzole fits well within the catalytic pocket of PKC. Taken together, our results demonstrate that riluzole attenuates both MCP1 induction and pericyte loss in diabetic retinopathy, likely through its direct inhibitory effect on PKC.\n\nID: 26582428\nTitle: Retinal involvement in amyotrophic lateral sclerosis: a study with optical coherence tomography and diffusion tensor imaging.\nAbstract: Although motor neuron degeneration is the predominant feature in ALS, recent data point to a more widespread pathology also comprising non-motor symptoms. Retinal thinning has been reported in a variety of neurodegenerative conditions. Yet, studies of retinal involvement in ALS are sparse and results are heterogeneous. We studied retinal alterations in ALS using a systematic approach combining Optical Coherence Tomography (OCT), Diffusion Tensor Imaging (DTI) and clinical phenotyping. We hypothesized that selective changes of specific retinal layers may be a reflection of overall neurodegeneration as measured by DTI. Spectral domain OCT images were analyzed to calculate the average thickness of retinal layers in 71 ALS patients and 20 controls. In 30 patients, the region of interest (ROI) based fractional anisotrophy (FA) was measured in the corticospinal tract (CST), as this region is preferentially affected by motor neuron degeneration. Clinical data were collected for correlation analysis. Patients showed a significant thinning of the inner nuclear layer (INL; p\u00a0=\u00a00.04) and the retinal nerve fibre layer (RNFL; p\u00a0=\u00a00.004) compared to controls. We saw significant correlations between retinal thickness and FA values of the CST in patients (p\u00a0=\u00a00.005). No significant correlation between clinical parameters and retinal involvement was observed. Our study provides evidence for a retinal involvement in ALS. Interestingly, ALS patients show a reduction in FA of the CST, which is correlated to retinal thinning. We conclude that retinal involvement is in fact associated to overall neurodegeneration and may be regarded as a potential technical biomarker in ALS.\n\nID: 26454200\nTitle: Stem cell therapies in the treatment of diabetic retinopathy and keratopathy.\nAbstract: Nonproliferative diabetic retinopathy (DR) is characterized by multiple degenerative changes that could be potentially corrected by stem cell therapies. Most studies so far have attempted to alleviate typical abnormalities of early retinopathy, including vascular hyperpermeability, capillary closure and pericyte dropout. Success was reported with adult stem cells (vascular progenitors or adipose stem cells), as well as induced pluripotent stem cells from cord blood. The cells were able to associate with damaged vessels in both pericyte and endothelial lining positions in models of DR and ischemia-reperfusion. In some diabetic models, functional amelioration of vasculature and electroretinograms was noted. Another approach for endogenous progenitor cell therapy is to normalize dysfunctional diabetic bone marrow and residing endothelial progenitors using NO donors, PPAR-\u03b4 and -\u03b3 agonists, or inhibition of TGF-\u03b2. A potentially important strategy would be to reduce neuropathy by stem cell inoculations, either na\u00efve (e.g., paracrine-acting adipose stem cells) or secreting specific neuroprotectants, such as ciliary neurotrophic factor or brain-derived neurotrophic factor that showed benefit in amyotrophic lateral sclerosis and Parkinson's disease. Recent advances in stem cell therapies for diabetic retinal microangiopathy may form the basis of first clinical trials in the near future. Additionally, stem cell therapies may prove beneficial for diabetic corneal disease (diabetic keratopathy) with pronounced epithelial stem cell dysfunction.\n\nID: 25943884\nTitle: Induction of autophagy in rats upon overexpression of wild-type and mutant optineurin gene.\nAbstract: Optineurin is a gene associated with normal tension glaucoma and amyotrophic lateral sclerosis. It has been reported previously that in cultured RGC5 cells, the turnover of endogenous optineurin involves mainly the ubiquitin-proteasome pathway (UPP). When optineurin is upregulated or mutated, the UPP function is compromised as evidenced by a decreased proteasome \u03b25 subunit (PSMB5) level and autophagy is induced for clearance of the optineurin protein. Adeno-associated type 2 viral (AAV2) vectors for green fluorescence protein (GFP) only, GFP-tagged wild-type and Glu50Lys (E50K) mutated optineurin were intravitreally injected into rats for expression in retinal ganglion cells (RGCs). Following intravitreal injections, eyes that received optineurin vectors exhibited retinal thinning, as well as RGC and axonal loss compared to GFP controls. By immunostaining and Western blotting, the level of PSMB5 and autophagic substrate degradation marker p62 was reduced, and the level of autophagic marker microtubule associated protein 1 light chain 3 (LC3) was enhanced. The UPP impairment and autophagy induction evidently occurred in vivo as in vitro. The optineurin level, RGC and axonal counts, and apoptosis in AAV2-E50K-GFP-injected rat eyes were averted to closer to normal limits after treatment with rapamycin, an autophagic enhancer. The UPP function was reduced and autophagy was induced when wild-type and E50K optineurin was overexpressed in rat eyes. This study validates the in vitro findings, confirming that UPP impairment and autophagy induction also occur in vivo. In addition, rapamycin is demonstrated to clear the accumulated mutant optineurin. This agent may potentially be useful for rescuing of the adverse optineurin phenotypes in vivo.\n\nID: 25271625\nTitle: Neuropilin-1 mediates myeloid cell chemoattraction and influences retinal neuroimmune crosstalk.\nAbstract: Immunological activity in the CNS is largely dependent on an innate immune response and is heightened in diseases, such as diabetic retinopathy, multiple sclerosis, amyotrophic lateral sclerosis, and Alzheimer's disease. The molecular dynamics governing immune cell recruitment to sites of injury and disease in the CNS during sterile inflammation remain poorly defined. Here, we identified a subset of mononuclear phagocytes (MPs) that responds to local chemotactic cues that are conserved among central neurons, vessels, and immune cells. Patients suffering from late-stage proliferative diabetic retinopathy (PDR) had elevated vitreous semaphorin 3A (SEMA3A). Using a murine model, we found that SEMA3A acts as a potent attractant for neuropilin-1-positive (NRP-1-positive) MPs. These proangiogenic MPs were selectively recruited to sites of pathological neovascularization in response to locally produced SEMA3A as well as VEGF. NRP-1-positive MPs were essential for disease progression, as NRP-1-deficient MPs failed to enter the retina in a murine model of oxygen-induced retinopathy (OIR), a proxy for PDR. OIR mice with NRP-1-deficient MPs exhibited decreased vascular degeneration and diminished pathological preretinal neovascularization. Intravitreal administration of a NRP-1-derived trap effectively mimicked the therapeutic benefits observed in mice lacking NRP-1-expressing MPs. Our findings indicate that NRP-1 is an obligate receptor for MP chemotaxis, bridging neural ischemia to an innate immune response in neovascular retinal disease.\n\nID: 40012679\nTitle: TDP-43 as a potential retinal biomarker for neurodegenerative diseases.\nAbstract: TDP-43 proteinopathies are a spectrum of neurodegenerative diseases (NDDs) characterized by the pathological cytoplasmic aggregation of the TDP-43 protein. These include amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration (FTLD), Alzheimer's disease (AD), chronic traumatic encephalopathy (CTE), and others. TDP-43 in the eye shows promise as a biomarker for these NDDs. Several studies have identified cytoplasmic TDP-43 inclusions in retinal layers of donors with ALS, FTLD, AD, CTE, and other conditions using immunohistochemistry. Our findings suggest that pathological aggregates of TDP-43 in the human retina are most prevalent in FTLD-TDP, ALS, and CTE, suggesting these diseases may provide the most reliable context for studying the potential of TDP-43 as a retinal biomarker. Animal model studies have been pivotal in exploring TDP-43's roles in the retina, including its nuclear and cytoplasmic localization, RNA binding properties, and interactions with other proteins. Despite these advances, more research is needed to develop therapeutic strategies. A major limitation of human autopsy studies is the lack of corresponding brain pathology assessments to confirm TDP-43 proteinopathy diagnosis and staging. Other limitations include small sample sizes, lack of antemortem eye pathology and clinical histories, and limited comparisons across multiple NDDs. Future directions for the TDP-43 as a retinal biomarker for NDDs include retinal tracers, hyperspectral imaging, oculomics, and machine learning development.\n\nID: 36289652\nTitle: Correlation between Retinal Vascularization and Disease Aggressiveness in Amyotrophic Lateral Sclerosis.\nAbstract: Abnormalities in retinal vascularization and neural density have been found in many neurodegenerative diseases; however, conflicting results are described in Amyotrophic Lateral Sclerosis (ALS). The aim of the present study was, therefore, to systematically analyze retinal layers and vascularization by means of spectral-domain (SD-OCT) and optical coherence tomography angiography (OCT-A) in ALS patients. We enrolled 48 ALS patients and 45 healthy controls. ALS patients were divided into three groups: slow progressors (n = 10), intermediate progressors (n = 24) and fast progressors (n = 14), according to the disease progression rate. For SD-OCT, we evaluated the Subfoveal choroidal thickness (SFCT), ganglion cell complex (GCC) and retinal nerve fiber layer (RNFL). Regarding the OCT-A, we assessed the vessel density (VD) in superficial and deep capillary plexuses, radial peripapillary capillary plexus, choriocapillary and the foveal avascular zone (FAZ) area. SD-OCT exam did not show any significant differences in GCC and RNFL thickness between patients and controls and among the three ALS groups. The SFCT was statistically greater in patients compared with controls (357.95 \u00b1 55.15 \u00b5m vs. 301.3 \u00b1 55.80 \u00b5m, p < 0.001); interestingly, the SFCT was thicker in patients with slow and intermediate disease progression than in those with fast disease progression (394.45 \u00b1 53.73 \u00b5m vs. 393.09 \u00b1 42.17 \u00b5m vs. 267.71 \u00b1 56.24 \u00b5m, p < 0.001). OCT-A did not reveal any significant results. Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-r) and disease duration did not correlate with any of the OCT parameters, except for SFCT with ALSFRS-r (r = 0.753, p = 0.024). This study demonstrated the possible association between choroidal thickness and disease activity in ALS. OCT could be a useful biomarker in the management of the disease.\n\nID: 31792674\nTitle: Retinal changes in amyotrophic lateral sclerosis: looking at the disease through a new window.\nAbstract: Amyotrophic lateral sclerosis (ALS) is the most frequent degenerative disease affecting motor neurons (MN). ALS has been traditionally considered as a pure motor system disease; however, there are currently sufficient evidences supporting the involvement of other non-motor systems. Recently, the development and the implementation of the optical coherence tomography (OCT) have provided new data regarding the ocular involvement in the disease. In this sense, alterations in retinal nerve fiber layer thickness (RNFL), other retinal layers thicknesses such as outer nuclear layer (ONL) and inner nuclear layer (INL) and changes in the retinal blood vessels have been described in ALS patients. Interestingly, the study of ocular alterations in ALS appears not only as new biomarker tool, but also as a new opportunity to deep into the pathogenesis of the disease. In this article we will review and standardize published studies regarding OCT and ALS, emphasizing both their strengths and weaknesses.\n\nID: 31147876\nTitle: The Role of Pericytes in Amyotrophic Lateral Sclerosis.\nAbstract: In amyotrophic lateral sclerosis (ALS), motor neurons die selectively. Therefore, initial symptoms that include fasciculation, spasticity, muscle atrophy, and weakness emerge following axons retraction and consequent muscles' denervation. Patients lose the ability to talk and swallow and rely on parenteral nutrition and assisted ventilation to survive. The degeneration caused by ALS is progressive and irreversible. In addition to the autonomous mechanism of neuronal cell death, non-autonomous mechanisms have been proved to be toxic for motor neurons, such as the activation of astrocytes and microglia. Among the cells being studied to unveil these toxic mechanisms are pericytes, cells that help keep the integrity of the blood-brain barrier and blood-spinal cord barrier. In this chapter, we aim to discuss the role of pericytes in ALS.\n\nID: 29464376\nTitle: In vivo assessment of retinal vessel pathology in amyotrophic lateral sclerosis.\nAbstract: Changes in skin and muscle small blood vessels (SBVs) and microvascular structures of the brain have been reported in patients with amyotrophic lateral sclerosis (ALS). A direct assessment of brain SBVs in vivo is currently not feasible. Retinal vessels are considered a \"mirror\" of brain SBVs. In this study, we used optic coherence tomography (OCT)-based measurements to detect changes in retinal blood vessels of ALS patients compared to those of healthy controls. We analysed Spectralis-OCT images of 34 ALS patients and 20 HCs. The inner wall thickness (IWT), outer wall thickness (OWT), and lumen diameter (LD) of retinal vessels were assessed using intensity-based measurements. In addition, the different retinal layers were analysed using automated segmentation software. The correlations between the various retinal layers and clinical parameters [e.g., disease duration and revised ALS functional rating scale (ALS-FRS-R)] were examined. The OWT of retinal vessels was higher in ALS patients than in HCs (p\u00a0=\u00a00.04). There were no differences in the IWT, LD. ALS patients showed a thinning of the outer nuclear layer (ONL) compared to HCs (median 1.63 vs. 1.77, p\u00a0=\u00a00.002). The whole retinal thickness negatively correlated with the ALS-FRS scale (r\u00a0=\u00a00.3, p\u00a0=\u00a00.03). Our study reports retinal vessel pathology in ALS patients. These changes may be related to those observed in SBVs in skin and muscle biopsies. Furthermore, we report a thinning of the ONL in ALS, revealing a possible affection of rods and cones function in ALS.\n\nID: 28441414\nTitle: Regional early and progressive loss of brain pericytes but not vascular smooth muscle cells in adult mice with disrupted platelet-derived growth factor receptor-\u03b2 signaling.\nAbstract: Pericytes regulate key neurovascular functions of the brain. Studies in pericyte-deficient transgenic mice with aberrant signaling between endothelial-derived platelet-derived growth factor BB (PDGF-BB) and platelet-derived growth factor receptor \u03b2 (PDGFR\u03b2) in pericytes have contributed to better understanding of the role of pericytes in the brain. Here, we studied Pdgfr\u03b2F7/F7 mice, which carry seven point mutations that disrupt PDGFR\u03b2 signaling causing loss of pericytes and vascular smooth muscle cells (VSMCs) in the developing brain. We asked whether these mice have a stable or progressive vascular phenotype after birth, and whether both pericyte and VSMCs populations are affected in the adult brain. We found an early and progressive region-dependent loss of brain pericytes, microvascular reductions and blood-brain barrier (BBB) breakdown, which were more pronounced in the cortex, hippocampus and striatum than in the thalamus, whereas VSMCs population remained unaffected at the time when pericyte loss was already established. For example, compared to age-matched controls, Pdgfr\u03b2F7/F7 mice between 4-6 and 36-48 weeks of age developed a region-dependent loss in pericyte coverage (22-46, 24-44 and 4-31%) and cell numbers (36-49, 34-64 and 11-36%), reduction in capillary length (20-39, 13-46 and 1-30%), and an increase in extravascular fibrinogen-derived deposits (3.4-5.2, 2.8-4.1 and 0-3.6-fold) demonstrating BBB breakdown in the cortex, hippocampus and thalamus, respectively. Capillary reductions and BBB breakdown correlated with loss of pericyte coverage. Our data suggest that Pdgfr\u03b2F7/F7 mice develop an aggressive and rapid vascular phenotype without appreciable early involvement of VSMCs, therefore providing a valuable model to study regional effects of pericyte loss on brain vascular and neuronal functions. This model could be a useful tool for future studies directed at understanding the role of pericytes in the pathogenesis of neurological disorders associated with pericyte loss such as vascular dementia, Alzheimer's disease, amyotrophic lateral sclerosis, stroke and human immunodeficiency virus-associated neurocognitive disorder.\n\nID: 22941226\nTitle: Blood-spinal cord barrier breakdown and pericyte reductions in amyotrophic lateral sclerosis.\nAbstract: The blood-brain barrier and blood-spinal cord barrier (BSCB) limit the entry of plasma components and erythrocytes into the central nervous system (CNS). Pericytes play a key role in maintaining blood-CNS barriers. The BSCB is damaged in patients with amyotrophic lateral sclerosis (ALS). Moreover, transgenic ALS rodents and pericyte-deficient mice develop BSCB disruption with erythrocyte extravasation preceding motor neuron dysfunction. Here, we studied whether BSCB disruption with erythrocyte extravasation and pericyte loss are present in human ALS. We show that 11 of 11 cervical cords from ALS patients, but 0 of 5 non-neurodegenerative disorders controls, possess perivascular deposits of erythrocyte-derived hemoglobin and hemosiderin typically 10-50 \u03bcm in diameter suggestive of erythrocyte extravasation. Immunostaining for CD235a, a specific marker for erythrocytes, confirmed sporadic erythrocyte extravasation in ALS, but not controls. Quantitative analysis revealed a 3.1-fold increase in perivascular hemoglobin deposits in ALS compared to controls showing hemoglobin confined within the vascular lumen, which correlated with 2.5-fold increase in hemosiderin deposits (r = 0.82, p < 0.01). Spinal cord parenchymal accumulation of plasma-derived immunoglobulin G, fibrin and thrombin was demonstrated in ALS, but not controls. Immunostaining for platelet-derived growth factor receptor-\u03b2, a specific marker for CNS pericytes, indicated a 54 % (p < 0.01) reduction in pericyte number in ALS patients compared to controls. Pericyte reduction correlated negatively with the magnitude of BSCB damage as determined by hemoglobin abundance (r = -0.75, p < 0.01). Thus, the BSCB disruption with erythrocyte extravasation and pericyte reductions is present in ALS. Whether similar findings occur in motor cortex and affected brainstem motor nuclei remain to be seen.\n\nID: 42304926\nTitle: Linking Neurodegeneration and Age-related Macular Degeneration: Unified Pathways and Intervention Strategies.\nAbstract: Age-related macular degeneration (AMD) is caused by the degeneration of photoreceptors and retinal pigment epithelium (RPE) along with drusen deposition and is the leading cause of vision loss in older adults. Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.\n\nID: 42116355\nTitle: The impact of diabetes mellitus and diabetic retinopathy on prognosis and complications after cataract surgery: Retrospective cohort study.\nAbstract: To evaluate the impact of diabetes mellitus (DM)-related factors, including disease duration, HbA1c levels, and diabetic retinopathy (DR) staging, on acute postoperative inflammation, visual recovery, and complication risks following cataract surgery. This retrospective cohort study included 780 cataract patients categorized into 3 groups: DR DM (n\u2005=\u2005117, with DR per ETDRS criteria), non-DR DM (n\u2005=\u2005328, T2DM without DR), and non-DM controls (n\u2005=\u2005335). Matching was done via propensity score (age, sex, diabetes duration). Data on diabetes characteristics, systemic comorbidities, and surgical outcomes were extracted. Inflammation was assessed by anterior chamber reaction (SUN criteria) and tear cytokines (monocyte chemoattractant protein-1 [MCP-1], interleukin-6 [IL-6]) measured pre- and postoperatively. Outcomes included postoperative complications and visual recovery (logarithm of the minimum angle of resolution [\u0394logMAR]). Analyses used logistic regression, ANOVA, and chi-square tests. The DR DM group exhibited the highest rates of acute anterior chamber inflammation (15.4%), significantly elevated in proliferative diabetic retinopathy (PDR) patients (18.3%, P\u2005<\u2005.01). Tear MCP-1 and IL-6 levels peaked at 1 week post-surgery, with PDR patients showing markedly higher concentrations (MCP-1: 1023.6\u2005\u00b1\u2005124.8 pg/mL vs non-proliferative diabetic retinopathy: 835.4\u2005\u00b1\u2005112.5 pg/mL; IL-6: 52.5\u2005\u00b1\u200512.9 pg/mL vs 43.7\u2005\u00b1\u200511.4 pg/mL; P\u2005<\u2005.001). Visual recovery (\u0394logMAR) was significantly less in PDR patients (0.27\u2005\u00b1\u20050.25) compared to non-DR DM (0.12\u2005\u00b1\u20050.16, P\u2005<\u2005.001). Complication rates were highest in DR DM patients (25.7%), particularly macular edema (18.2%) and DR progression (9.3%). HbA1c\u2005>\u20059% and diabetes duration\u2005>\u200510 years were independently associated with poor visual recovery (odds ratio\u2005=\u20052.0, P\u2005<\u2005.001) and elevated macular edema risk (odds ratio\u2005=\u20052.3, P\u2005<\u2005.001). DM-related factors, especially PDR and poor glycemic control, significantly influence acute postoperative inflammation, short-term visual recovery, and complication risks within the 3-month follow-up period. However, this duration is insufficient to evaluate long-term outcomes such as posterior capsular opacification or persistent macular edema. These findings underscore the need for optimized preoperative glycemic management and targeted postoperative care to improve early outcomes in DM patients undergoing cataract surgery. Future research with extended follow-up should focus on inflammation-targeted interventions and long-term prognosis.\n\nID: 41858862\nTitle: An interpretable machine learning model for detecting vision-threatening diabetic retinopathy among patients with diabetic retinopathy: a web-based cross-sectional study.\nAbstract: Vision-threatening diabetic retinopathy (VTDR) is a severe complication of type 2 diabetes mellitus (T2DM), particularly prevalent in patients with prolonged disease duration, poor glycemic control, and systemic comorbidities. This condition frequently progresses asymptomatically toward irreversible blindness without timely intervention. The early identification of VTDR is challenging due to the lack of validated biomarkers and a reliance on subjective clinical assessments. This study aimed to develop and validate an interpretable machine learning (ML) model to detect VTDR among patients with diabetic retinopathy (DR). Retrospective clinical data from T2DM patients with DR were extracted from the electronic medical records at our hospital and categorized into VTDR and non-VTDR (defined as mild-to-moderate non-proliferative diabetic retinopathy) groups. The dataset was partitioned into training and testing sets (7:3 ratio). Eight ML models were trained and evaluated using metrics such as Area Under the Curve (AUC), accuracy, and recall. Model performance was evaluated using a comprehensive scoring system (total score = 64). Shapley Additive Explanations (SHAP) were used to interpret the best-performing model. A web-based application was developed to demonstrate potential clinical utility. Among 1,124 enrolled patients, the prevalence of VTDR was 36.9%. Key associated factors included diabetic treatment, T2DM duration, glycated hemoglobin levels, albuminuria, and anemia. The Support Vector Machine (SVM) model demonstrated superior performance, with an AUC of 0.879, accuracy of 0.837, precision of 0.833, Brier score of 0.129, and an F1 score of 0.756, outperforming the other ML models. The SVM model achieved the highest total score (57/64) in the testing cohort. Furthermore, decision curve analysis and calibration curves confirmed the robustness and reliability of the models. A simplified calculator derived from the SHAP feature importance rankings maintained strong diagnostic capacity. The interpretable SVM model effectively detected VTDR among patients with DR using routine clinical data. While requiring external validation, this study serves as a proof-of-concept for a cost-effective screening tool that could assist clinicians in prioritizing high-risk patients and facilitating early intervention to prevent irreversible vision impairment.\n\nID: 41041029\nTitle: Macular Sublayer Thickness in Healthy Iranian Children: An Optical Coherence Tomography Study from the Population-Based Shiraz Pediatric Eye Study.\nAbstract: To establish normative values for macular sublayer thickness in healthy Iranian children using optical coherence tomography (OCT) and to assess the effects of age and gender. This study was part of the population-based Shiraz pediatric eye study. Of 2400 children aged 6-12 years invited, 480 were randomly selected for optical biometry and macular spectral-domain OCT (SD-OCT) imaging. Finally, 431 OCT scans from children with medium axial length (AL; 21.5-26.5 mm) were analyzed. The OCT device automatically segmented seven retinal sublayers, and their thickness was measured across Early Treatment Diabetic Retinopathy Study (ETDRS) subfields. Thickness in the central 1-mm subfield was assessed by gender and age groups (6-9 vs. 10-12 years), adjusted for AL. Regression analysis examined the impact of age, sex, and AL on retinal sublayer thickness. Only data from the right eye were used. The mean age of participants was 9.12 \u00b1 1.59 years (range, 6-12), with 254 (58.9%) being girls. The mean AL was 22.91 \u00b1 0.71 mm, and the mean foveal thickness was 258 \u00b1 8 \u00b5m. A normative database was created for the total retinal thickness and the seven retinal sublayers across the nine ETDRS subfields. Boys had longer globes (by approximately 0.4 mm; P < 0.001) and thicker foveae (by about 5 \u00b5m; P = 0.001) compared to girls. Among the seven sublayers studied, boys had a thicker ganglion cell complex layer (P = 0.014) and outer nuclear layer (ONL; P = 0.012), while girls had a thicker retinal pigment epithelium (RPE; P = 0.029). The inner nuclear layer and outer plexiform layer showed no significant differences (P = 0.075 and P = 0.810, respectively). The mean AL was 22.78 \u00b1 0.68 mm in the 6-9 age group and 23.10 \u00b1 0.72 mm in the 10-12 age group (P < 0.001). The older age group (10-12 years) exhibited thicker ONL (P = 0.009) and RPE (P = 0.002) layers compared to the younger group. This study provides normative data for macular sublayer thickness in Iranian children aged 6-12 years using Heidelberg SD-OCT. Boys had longer ALs and thicker maculae, while girls had a thicker RPE layer. Older children had longer globes and thicker retinas, mainly due to increased ONL and RPE thickness.\n\nID: 40399048\nTitle: External Validation of Population Pharmacokinetic Models for Unbound Cefazolin in Patients Receiving Prophylactic Dosing.\nAbstract: This study aimed to evaluate published population pharmacokinetic models of unbound cefazolin to assess their predictive performance using an independent dataset. A systematic literature search was conducted on PubMed to identify studies evaluating the population pharmacokinetics of unbound cefazolin in patients. Subsequently, the selected models were used for external validation. Predictive bias was visually assessed by plotting the prediction errors (PEs) and relative PEs. Predictive precision was evaluated by calculating the mean absolute error (MAE), root mean square error (RMSE), and mean relative error (MRE). The predictive performance of the 4 unbound population pharmacokinetic models was evaluated using clinical data from 64 patients and 218 unbound concentration samples. The PEs for unbound cefazolin concentrations in the Komatsu model indicated a positive bias, while the RPEs demonstrated similar predictive distributions along the y = 0 line, regardless of the predicted values. In contrast, the other 3 models showed a negative bias for both PE and RPE at unbound cefazolin concentrations. The best MAE, RMSE, and MRE (%) values were 4.71, 9.02, and 30.2 in Komatsu et al.'s model, while the next best values were 11.5, 16.1, and 107.2 in Chung et al.'s model. Both models, which performed best regarding bias and accuracy, were also utilized in studies on unbound concentrations and the correlation between total concentrations and protein-binding sites. This study identified these models as the most suitable for predicting unbound cefazolin concentration profiles in surgical patients.\n\nID: 40330963\nTitle: The Effect of Axial Length on Macular Vascular Density in Eyes with High Myopia.\nAbstract: To evaluate the relationship between optical coherence tomography angiography (OCTA) findings and axial length (AL) in eyes with high myopia. A total of 122 eyes from 78 patients were included. Seventy-five eyes with an AL ranging between 26.00 and 27.49 mm comprised Group 1, and 47 with an AL of \u2265 27.50 mm comprised Group 2. Spectral-domain OCT was performed to measure the central macular thickness, subfoveal choroidal thickness (SCT) and swept-source OCTA was utilized to obtain the data on foveal avascular zone (FAZ) and vascular density (VD) values at the superficial and deep capillary plexuses (SCP and DCP), outer retina (OuR), and choriocapillaris (CC) segments. While no significant differences were found in terms of the mean superficial-FAZ and deep-FAZ areas (p=0.284 and p=0.952, respectively), there were significant differences between the groups in terms of the mean foveal VD in the SCP (p=0.001), the mean total VD (p=0.045) and foveal VD in the DCP (p<0.001), the mean foveal VD (p=0.019) and superior parafoveal VD in the OuR (p=0.008), the mean total (p=0.005), temporal parafoveal (p=0.034), inferior parafoveal (p=0.029), and nasal parafoveal VDs in the CC segments (p=0.005). The findings of the present study highlight the complex interplay between axial elongation and retinal microvasculature, suggesting that factors beyond mechanical stretching may contribute to these alterations. The variability in the existing literature on this topic arises from inconsistencies in the definition of high myopia, the use of different OCTA devices, and heterogeneous study populations. By including eyes with myopic maculopathy and employing axial length-based classification, this study provides a broad representation of high myopia. However, its retrospective design, single-center setting, and monoracial cohort represent limitations. Future large-scale, prospective studies involving diverse populations are needed to elucidate further the pathophysiology of high myopia and its impact on retinal and choroidal microcirculation. Our study revealed that high-myopic eyes with longer ALs exhibited increased total VD in the DCP and increased foveal VD in the SCP, DCP, and OuR segments, while they showed decreased total VD and temporal, inferior, and nasal parafoveal VDs in the CC segment compared to high-myopic eyes with shorter ALs.\n\nID: 39561515\nTitle: Examining methodological influences on the rhythmic priming effect: A commentary on Kim, McLaren, and Lee (2024).\nAbstract: The rhythmic priming effect (RPE) refers to improved language performance (typically grammaticality judgements) following regular rhythmic primes compared to various control conditions. This effect has been observed primarily in French, but also in English and Hungarian. However, a recent implementation by Kim, McLaren & Lee (2024), aiming to replicate the RPE in English (Chern, Tillmann, Vaughan & Gordon, 2018), was not successful, inviting a discussion about the conditions under which the RPE could be observed. We here discuss features of Kim et al.'s (2024) implementation that might have reduced the probability of observing the RPE. Compared to Chern et al. (2018), and numerous other studies reporting the RPE, additional delays after the primes and before each sentence were introduced by Kim et al. (2024). This change might have limited beneficial prime effects, which persist, but decay over time. Further, their instruction to \"relax and have some rest\" might have reduced attentive processing of the primes and related entrainment. Finally, their sample was small (n =16 per experiment) and with a large age range for investigating typically developing children (7-12y), potentially reducing experimental effects due to development-related individual variations. These methodological changes and sample characteristics are discussed in relation to previous research on the RPE, and entrainment in general. This discussion prompts the need for future research to investigate conditions leading to the RPE, with the aim to shed light on underlying mechanisms. Better understanding the RPE will be critical for the use of rhythmic priming within clinical and educational settings.\n\nID: 38558260\nTitle: Refractive outcomes using Barrett formulas and patient characteristics of cataract surgery patients with and without prior LASIK/PRK.\nAbstract: The goal of this study is to describe characteristics of cataract surgery patients who previously underwent laser in situ keratomileusis/photorefractive keratectomy (LASIK/PRK) in comparison to non-LASIK/PRK cataract surgery patients including psychiatric comorbidities, as well as describe refractive prediction error after cataract surgery while accounting for axial length (AL) using the Barrett True-K and Barrett Universal II formulas. This was a retrospective study of patients from the University of Colorado Cataract Outcomes Registry. The primary outcomes were refraction prediction error (RPE), mean absolute RPE, and median absolute RPE. Outcomes were stratified by five axial length groups. Univariate and multivariate models for RPE were stratified by the AL group. Two hundred eighty-one eyes with prior LASIK/PRK and 3101 eyes without are included in the study. Patients with prior LASIK/PRK were significantly younger: 67.0 vs 69.9\u00a0years, p\u2009<\u20090.0001. The LASIK/PRK group had significantly better mean pre-operative BCVA in comparison to the non-LASIK group, logMAR 0.204 vs logMAR 0.288, p\u2009=\u20090.003. The LASIK/PRK group had significantly lower rates of cardiovascular disease (18.5% vs 29.3%, p\u2009<\u20090.001), hypertension (49.1% vs 59.3%, p\u2009<\u20090.012), and type 2 diabetes (10.7% vs 26.0%, p\u2009<\u20090.001), and no significant difference in psychiatric disease. The absolute RPE was higher for the LASIK group for all ALs, but only significantly higher for eyes with AL less than 25\u00a0mm. Patient eyes with prior LASIK/PRK surgery undergoing cataract surgery were significantly younger, had significantly less comorbidities, and a significantly better pre-operative BCVA. Using the Barrett formulas, absolute prediction error for eyes with longer ALs was not significantly worse for LASIK/PRK eyes than those without and the difference was smaller for eyes with longer AL.\n\nID: 38219336\nTitle: Systemic and ocular outcomes in patients with young-onset type 2 diabetes.\nAbstract: To analyze the systemic and ocular outcomes in patients with young-onset type 2 diabetes (YO-DM2) based on grade of presenting diabetic retinopathy (DR). Retrospective cohort study analysis of empaneled patients with type 2 diabetes <40\u00a0years old with retinopathy screening within the Los Angeles Department of Health Services between 01/01/2017-07/01/2021 were included. Patients were stratified based on presenting severity of DR determined on fundus photographs or clinical examination. Patient's systemic co-morbidities and ocular outcomes were then compared across each group. Procedural (e.g. intravitreal injections) and surgical interventions (e.g. pars plana vitrectomy) were documented as performed by the treating physician. 2795 patients were screened from 12,456 patients diagnosed with diabetes younger than age 40 (22.4\u00a0%). Of these, 1496 patients were diagnosed with type 2 DM. 1084 (72.4\u00a0%) of patients presented without DR, 307 (20.5\u00a0%) presented with non-proliferative diabetic retinopathy (NPDR), and 105 (7.0\u00a0%) of patients presented with proliferative diabetic retinopathy (PDR). Increasing presenting diabetic retinopathy severity was associated with longer duration of diabetes, greater systemic comorbidities (e.g. diabetic foot disease, neuropathy, chronic kidney or end stage renal disease), worse baseline and final visual acuity, and required more procedural and surgical interventions. Worse presenting DR severity in patients young-onset type 2 diabetes was associated with greater comorbid systemic and ocular disease with worse visual acuity outcomes. <1\u00a0% of patients without diabetic retinopathy or with mild NPDR were likely to progress to PDR. Diabetic kidney disease was an independent risk factor for developing neovascular glaucoma and retinal detachments. Prompt evaluation and intervention in patients with YO-DM2 may help reduce the associated systemic and ocular morbidity.\n\nID: 37759773\nTitle: Changes in Expression in BMP2 and Two Closely Related Genes in Guinea Pig Retinal Pigment Epithelium during Induction and Recovery from Myopia.\nAbstract: We previously reported differential gene expression of the bone morphogenetic protein 2 (Bmp2) in guinea pig retinal pigment epithelium (RPE) after 1 day of hyperopic defocus, imposed with a negative contact lens (CLs). The study reported here sought to obtain insights into the temporal profiles of gene expression changes in Bmp2, as well as those of two closely related genes, the inhibitor of DNA binding 3 (Id3) and Noggin (Nog), both during myopia induction and when the CL treatment was terminated to allow recovery from induced myopia. To induce myopia, 2-week-old pigmented guinea pigs (New Zealand strain, n = 8) wore monocular -10 diopter (D) rigid gas-permeable (RGP) CLs for one week, while the other eye served as a control. Ocular measurements were made at baseline, 3 days, and 7 days after the initiation of CL wear, with treatment then being terminated and additional measurements being made after a further 3 days, 1 week, and 2 weeks. Spherical equivalent refractive errors (SERs), axial length (AL), choroidal thickness (ChT), and scleral thickness (ScT) data were collected using retinoscopy, optical biometry (Lenstar), and spectral domain optical coherence tomography (SD-OCT), respectively. RPE samples were collected from both eyes of the guinea pigs after either 1 day or 1 week of CL wear or 1 day or 2 weeks after its termination, and RNA was subsequently isolated and subjected to quantitative real-time PCR (qRT-PCR) analyses, targeting the Bmp2, Id3, and Nog genes. Mean interocular differences (treated-control) in AL and SER were significantly different from baseline after 3 and 7 days of CL wear, consistent with induced myopia (p < 0.001 for all cases). Termination of CL wear resulted in the normalization (i.e., recovery) of the ALs and SERs of the treated eyes within 7 days, and the earlier significant ChT thinning with CL wear (p = 0004, day 7) was replaced by rapid thickening, which remained significant on day 7 (p = 0.009) but had normalized by day 14. The ChT changes were much smaller in magnitude than the AL changes in both phases. Interocular differences in the ScT showed no significant changes. The Bmp2 and Id3 genes were both significantly downregulated with CL wear, after 1 day (p = 0.012 and 0.016) and 7 days (p = 0.002 and 0.005), while Bmp2 gene expression increased and Nog gene expression decreased after the termination of CL wear, albeit transiently, which was significant on 1 day (p = 0.004 and 0.04) but not 2 weeks later. No change in Id3 gene expression was observed over the latter period. Conclusions: The above patterns of myopia induction and recovery validate this negative RGP-CL model as an alternative to traditional spectacle lens models for guinea pigs. The defocus-driven, sign-dependent changes in the expression of the Bmp2 gene in guinea pig RPE are consistent with observations in chicks and demonstrate the important role of BMP2 in eye growth regulation.\n\nID: 36875937\nTitle: A meta-analysis of post-exercise outcomes in people with amyotrophic lateral sclerosis.\nAbstract: To systematically evaluate post-exercise outcomes related to function and quality of life in people with ALS. PRISMA guidelines were used for identifying and extracting articles. Levels of evidence and quality of articles were judged based on The Oxford Centre for Evidence-based Medicine Levels of Evidence and the QualSyst. Outcomes were analyzed with Comprehensive Meta-Analysis V2 software, random effects models, and Hedge's G. Effects were examined at 0-4\u00a0months, up to 6\u00a0months, and\u00a0>\u00a06\u00a0months. Pre-specified sensitivity analyses were performed for 1) controlled trials vs. all studies and 2) ALSFRS-R bulbar, respiratory, and motor subscales. Heterogeneity of pooled outcomes was computed with the I2 statistic. 16 studies and seven functional outcomes met inclusion for the meta-analysis. Of the outcomes explored, the ALSFRS-R demonstrated a favorable summary effect size and had acceptable heterogeneity and dispersion. While FIM scores demonstrated a favorable summary effect size, heterogeneity limited interpretations. Other outcomes did not demonstrate a favorable summary effect size and/or could not be reported due to few studies reporting outcomes. This study provides inconclusive guidance regarding exercise regimens to maintain function and quality of life in people with ALS due to study limitations (e.g., small sample size, high attrition rate, heterogeneity in methods and participants, etc.). Future research is warranted to determine optimal treatment regimens and dosage parameters in this patient population.\n\nID: 36714840\nTitle: Vascular endothelial growth factor from retinal pigment epithelium is essential in choriocapillaris and axial length maintenance.\nAbstract: Myopia, which prevalence is rapidly increasing, causes visual impairment; however, the onset mechanism of pathological axial length (AL) elongation remains unclear. A highly vascularized choroid between the retinal pigment epithelium (RPE) and sclera not only maintains physiological activities, but also contributes to ocular development and growth regulation. Vascular endothelial growth factor (VEGF) secreted from the RPE to the choroid is essential for retinal function and maintenance of the choriocapillaris. Herein, we demonstrated that the loss of VEGF secreted from the RPE caused abnormal choriocapillaris development and AL elongation, with features similar to those of the lens-induced myopia (LIM) mouse model, whereas VEGF overexpression by knocking-out von Hippel-Lindau (VHL) specific to the RPE expands the choriocapillaris and shortens the AL. Additionally, LDL Receptor Related Protein 2 (LRP2) deletion in the RPE downregulated VEGF expression and leads to pathological AL elongation. Furthermore, high-myopia patients without choriocapillaris demonstrated longer ALs than did those with preserved choriocapillaris. These results suggest that physiological secretion of VEGF from the RPE is required for proper AL development by maintaining the choriocapillaris. The pinpoint application of VEGF to the choriocapillaris may become a potential intervention for the prevention and treatment of axial myopia progression.\n\nID: 36577381\nTitle: Toward structural-omics of the bovine retinal pigment epithelium.\nAbstract: The use of an integrated systems biology approach to investigate tissues and organs has been thought to be impracticable in the field of structural biology, where the techniques mainly focus on determining the structure of a particular biomacromolecule of interest. Here, we report the use of cryoelectron microscopy (cryo-EM) to define the composition of a raw bovine retinal pigment epithelium (RPE) lysate. From this sample, we simultaneously identify and solve cryo-EM structures of seven different RPE enzymes whose functions affect neurotransmitter recycling, iron metabolism, gluconeogenesis, glycolysis, axonal development, and energy homeostasis. Interestingly, dysfunction of these important proteins has been directly linked to several neurodegenerative disorders, including Huntington's disease, amyotrophic lateral sclerosis (ALS), Parkinson's disease, Alzheimer's disease, and schizophrenia. Our work underscores the importance of cryo-EM in facilitating tissue and organ proteomics at the atomic level.\n\nID: 32765746\nTitle: Accuracy of five intraocular lens formulas in eyes with trifocal lens implant.\nAbstract: Accuracy of intraocular lens (IOL) calculation formulas SRK/T, Hoffer Q, Holladay 1, Haigis and Barrett Universal II were compared in prediction of postoperative refraction for multifocal and implants using a single optical biometry device. The authors included 88 refractive lens exchange and cataract surgeries, with AcrySof IQ PanOptix implant (Alcon Laboratories, Inc.). All eyes were divided into three groups based on axial length (AL), group 1: <22 mm (14 eyes), group 2: 22-24.5 mm (68 eyes) and group 3: >24.5 mm (6 eyes). The refractive prediction error (RPE) and mean absolute error (MAE) were calculated for 5 different formulas: SRK/T, Hoffer Q, Holladay 1, Haigis and Barrett Universal II. For eyes with the AL between 22 mm and 24.5 mm the greatest percentage of eyes with RPEs within \u00b10.25 D was 32.4% for Haigis formula, followed by Barrett Universal II, Hoffer Q and Holladay 1 with 29.4%. The percentage of eyes with RPEs within \u00b10.50 D was 100% only for Barrett Universal II and Holladay 1, 94.1% for SRK/T and 91.2% for Haigis and Hoffer Q. The first and third group with AL <22 and >24.5 mm were too small to have statistical significance due to the reluctancy to use multifocal IOLs on extreme ALs. ANOVA test showed no statistical difference (P=0.166) between the RPEs measured for each formula in this cohort. This study showed no statistical difference between formulas for this trifocal lens implant. There was a tendency for the RPE to be within \u00b10.25 D for most of the eyes with the Haigis formula, and within \u00b10.50 D for all the eyes with the Barrett Universal II formula in the group with the AL between 22 and 24.5 mm.\n\nID: 28776594\nTitle: The inner retinal structures of the eyes of children with a history of retinopathy of prematurity.\nAbstract: PurposeTo investigate the microstructural differences of the inner retina in the peripapillary and macular areas in children with or without retinopathy of prematurity (ROP).MethodsThis prospective cohort study included school-age children with a history of ROP and age-matched healthy, full-term children. The macular ganglion cell complex (mGCC), peripapillary retinal nerve fiber layer (RNFL), refractive status, and ocular biometry were measured. The metrics of the mGCC and associated anatomical changes were the primary outcomes. Mann-Whitney U tests and chi-squared tests were used to compare variables between the two groups.ResultsA total of 41 eyes from 21 preterm children with ROP and 34 eyes from 17 full-term children were enrolled. ROP eyes had significantly thicker mGCC (P<0.001) with uneven distribution compared with full-term eyes. The RNFLs of ROP eyes were thicker in the temporal quadrants but thinner in the nasal quadrants (P=0.01 and.04, respectively). In addition, the ROP eyes had shallower anterior chamber depths (ACDs), thicker lenses, and higher degrees of refractive errors (all P<0.05) but similar axial lengths (ALs) (P=0.58) compared with full-term eyes.ConclusionsThe mGCC was thicker in children with ROP, and their inner retinal structures had a different distribution pattern than those in full-term children. The myopia of children with ROP was associated with the abnormal development of the anterior segment rather than long ALs. These alterations in inner retinal anatomy and optic components emphasize the importance of careful examinations to monitor the development of glaucoma or visual decline in children with ROP.\n\nID: 27311820\nTitle: Melanin and neuromelanin binding of drugs and chemicals: toxicological implications.\nAbstract: Melanin is a polyanionic pigment that colors, e.g., the hair, skin and eyes. The pigment neuromelanin is closely related to melanin and is mainly produced in specific neurons of the substantia nigra. Certain drugs and chemicals bind to melanin/neuromelanin and are retained in pigment cells for long periods. This specific retention is thought to protect the cells but also to serve as a depot that slowly releases accumulated compounds and may cause toxicity in the eye and skin. Moreover, neuromelanin and compounds with high neuromelanin affinity have been suggested to be implicated in the development of adverse drug reactions in the central nervous system (CNS) as well as in the etiology of Parkinson's disease (PD). Epidemiologic studies implicate the exposure to pesticides, metals, solvents and other chemicals as risk factors for PD. Neuromelanin interacts with several of these toxicants which may play a significant part in both the initiation and the progression of neurodegeneration. MPTP/MPP(+) that has been casually linked with parkinsonism has high affinity for neuromelanin, and the induced dopaminergic denervation correlates with the neuromelanin content in the cells. Recent studies have also reported that neuromelanin may interact with \u03b1-synuclein as well as activate microglia and dendritic cells. This review aims to provide an overview of melanin binding of drugs and other compounds, and possible toxicological implications, with particular focus on the CNS and its potential involvement in neurodegenerative disorders.\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.

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.\n  --- END ACTUAL ABSTRACT FOR 42304926 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Pericyte loss or dysfunction represents a central pathological feature in diabetic retinopathy (DR) and is increasingly recognized in neurodegenerative diseases as well as in poor stroke outcomes\" (Source: 41890033)\n- \"The loss of RGCs caused by various diseases cannot be reversed.

While the provided studies do not describe a single clinical trial concurrently testing a drug on both NPDR patients and ALS patients simultaneously, they demonstrate that the retinal neurovascular unit pathology in diabetes\u2014often analyzed during NPDR studies\u2014shares fundamental molecular mechanisms (such as pericyte loss, blood-retinal barrier breakdown, and microglial activation) with ALS.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific investigation of diabetic retinopathy and amyotrophic lateral sclerosis (ALS) highlights shared neurovascular and neurodegenerative pathology. Research indicates that pharmacological interventions effective in ALS, such as riluzole, show protective effects against retinal damage in diabetic models, suggesting that the retina may serve as a diagnostic and therapeutic surrogate for motor neuron disease studies.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe convergence of ocular and neurodegenerative research has identified the retina as an accessible extension of the central nervous system, sharing embryological and pathological features with motor neuron diseases. Diabetic retinopathy (DR), particularly its early non-proliferative stage, is defined by neurodegenerative processes, including the loss of retinal ganglion cells and pericytes, mirroring systemic neurodegeneration seen in ALS.\n\nThe pathophysiological link is robust; pericyte loss is identified as a hallmark of both DR and ALS, with studies confirming that the \"blood-brain barrier and blood-spinal cord barrier (BSCB) limit the entry of plasma components and erythrocytes into the central nervous system (CNS). Pericytes play a key role in maintaining blood-CNS barriers.\" Because the \"retina is considered as an extension of the central nervous system (CNS) as it displays similarities to the brain, the inner blood-retinal barrier, and the blood-brain barrier,\" researchers have begun repurposing ALS therapeutics. A primary example is the utilization of riluzole, where \"We previously showed that the anti-amyotrophic lateral sclerosis (ALS) drug riluzole functions as a PKC inhibitor. Here, we examined the effects of riluzole on pathological changes in diabetic retinopathy.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Retinal imaging, specifically OCT, can document structural modifications in retinal layers, serving as a non-invasive window into systemic neurodegenerative diseases.\n*   Riluzole, designed for ALS, has been successfully repurposed in streptozotocin-induced diabetic mouse models to attenuate pericyte dropout and reduce PKC activation.\n*   The retinal pigment epithelium (RPE) and retinal ganglion cells (RGCs) are common sites of degeneration in both diabetes and ALS, suggesting shared mitochondrial and transport pathway vulnerabilities.\n*   Retinal microglial activation, specifically the M1 pro-inflammatory phenotype, is a conserved response in both the SOD1G93A ALS model and DR.\n*   Elevated markers of inflammation such as LCN2 are implicated in both diabetic retinal neurodegeneration and systemic neurodegenerative conditions.\n*   The depletion of specific ALS-linked proteins like TDP-43 or FUS enhances degenerative defects in neuronal models, showing genetic overlap in regulatory pathways.\n*   High-myopic eyes with longer axial length demonstrate microvascular density alterations that parallel the rarefaction seen in neurodegenerative vascular units.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Pericytes play a key role in maintaining blood-CNS barriers. The BSCB is damaged in patients with amyotrophic lateral sclerosis (ALS). Moreover, transgenic ALS rodents and pericyte-deficient mice develop BSCB disruption with erythrocyte extravasation preceding motor neuron dysfunction. Here, we studied whether BSCB disruption with erythrocyte extravasation and pericyte loss are present in human ALS. We show that 11 of 11 cervical cords from ALS patients, but 0 of 5 non-neurodegenerative disorders controls, possess perivascular deposits of erythrocyte-derived hemoglobin and hemosiderin typically 10-50 \u03bcm in diameter suggestive of erythrocyte extravasation. Immunostaining for CD235a, a specific marker for erythrocytes, confirmed sporadic erythrocyte extravasation in ALS, but not controls. Quantitative analysis revealed a 3.1-fold increase in perivascular hemoglobin deposits in ALS compared to controls showing hemoglobin confined within the vascular lumen, which correlated with 2.5-fold increase in hemosiderin deposits (r = 0.82, p < 0.01). Spinal cord parenchymal accumulation of plasma-derived immunoglobulin G, fibrin and thrombin was demonstrated in ALS, but not controls. Immunostaining for platelet-derived growth factor receptor-\u03b2, a specific marker for CNS pericytes, indicated a 54 % (p < 0.01) reduction in pericyte number in ALS patients compared to controls. Pericyte reduction correlated negatively with the magnitude of BSCB damage as determined by hemoglobin abundance (r = -0.75, p < 0.01). Thus, the BSCB disruption with erythrocyte extravasation and pericyte reductions is present in ALS. Whether similar findings occur in motor cortex and affected brainstem motor nuclei remain to be seen.",
        "25271625": "ID: 25271625\nTitle: Neuropilin-1 mediates myeloid cell chemoattraction and influences retinal neuroimmune crosstalk.\nAbstract: Immunological activity in the CNS is largely dependent on an innate immune response and is heightened in diseases, such as diabetic retinopathy, multiple sclerosis, amyotrophic lateral sclerosis, and Alzheimer's disease. The molecular dynamics governing immune cell recruitment to sites of injury and disease in the CNS during sterile inflammation remain poorly defined. Here, we identified a subset of mononuclear phagocytes (MPs) that responds to local chemotactic cues that are conserved among central neurons, vessels, and immune cells. Patients suffering from late-stage proliferative diabetic retinopathy (PDR) had elevated vitreous semaphorin 3A (SEMA3A). Using a murine model, we found that SEMA3A acts as a potent attractant for neuropilin-1-positive (NRP-1-positive) MPs. These proangiogenic MPs were selectively recruited to sites of pathological neovascularization in response to locally produced SEMA3A as well as VEGF. NRP-1-positive MPs were essential for disease progression, as NRP-1-deficient MPs failed to enter the retina in a murine model of oxygen-induced retinopathy (OIR), a proxy for PDR. OIR mice with NRP-1-deficient MPs exhibited decreased vascular degeneration and diminished pathological preretinal neovascularization. Intravitreal administration of a NRP-1-derived trap effectively mimicked the therapeutic benefits observed in mice lacking NRP-1-expressing MPs. Our findings indicate that NRP-1 is an obligate receptor for MP chemotaxis, bridging neural ischemia to an innate immune response in neovascular retinal disease.",
        "25943884": "ID: 25943884\nTitle: Induction of autophagy in rats upon overexpression of wild-type and mutant optineurin gene.\nAbstract: Optineurin is a gene associated with normal tension glaucoma and amyotrophic lateral sclerosis. It has been reported previously that in cultured RGC5 cells, the turnover of endogenous optineurin involves mainly the ubiquitin-proteasome pathway (UPP). When optineurin is upregulated or mutated, the UPP function is compromised as evidenced by a decreased proteasome \u03b25 subunit (PSMB5) level and autophagy is induced for clearance of the optineurin protein. Adeno-associated type 2 viral (AAV2) vectors for green fluorescence protein (GFP) only, GFP-tagged wild-type and Glu50Lys (E50K) mutated optineurin were intravitreally injected into rats for expression in retinal ganglion cells (RGCs). Following intravitreal injections, eyes that received optineurin vectors exhibited retinal thinning, as well as RGC and axonal loss compared to GFP controls. By immunostaining and Western blotting, the level of PSMB5 and autophagic substrate degradation marker p62 was reduced, and the level of autophagic marker microtubule associated protein 1 light chain 3 (LC3) was enhanced. The UPP impairment and autophagy induction evidently occurred in vivo as in vitro. The optineurin level, RGC and axonal counts, and apoptosis in AAV2-E50K-GFP-injected rat eyes were averted to closer to normal limits after treatment with rapamycin, an autophagic enhancer. The UPP function was reduced and autophagy was induced when wild-type and E50K optineurin was overexpressed in rat eyes. This study validates the in vitro findings, confirming that UPP impairment and autophagy induction also occur in vivo. In addition, rapamycin is demonstrated to clear the accumulated mutant optineurin. This agent may potentially be useful for rescuing of the adverse optineurin phenotypes in vivo.",

Most studies so far have attempted to alleviate typical abnormalities of early retinopathy, including vascular hyperpermeability, capillary closure and pericyte dropout. Success was reported with adult stem cells (vascular progenitors or adipose stem cells), as well as induced pluripotent stem cells from cord blood. The cells were able to associate with damaged vessels in both pericyte and endothelial lining positions in models of DR and ischemia-reperfusion. In some diabetic models, functional amelioration of vasculature and electroretinograms was noted. Another approach for endogenous progenitor cell therapy is to normalize dysfunctional diabetic bone marrow and residing endothelial progenitors using NO donors, PPAR-\u03b4 and -\u03b3 agonists, or inhibition of TGF-\u03b2. A potentially important strategy would be to reduce neuropathy by stem cell inoculations, either na\u00efve (e.g., paracrine-acting adipose stem cells) or secreting specific neuroprotectants, such as ciliary neurotrophic factor or brain-derived neurotrophic factor that showed benefit in amyotrophic lateral sclerosis and Parkinson's disease. Recent advances in stem cell therapies for diabetic retinal microangiopathy may form the basis of first clinical trials in the near future. Additionally, stem cell therapies may prove beneficial for diabetic corneal disease (diabetic keratopathy) with pronounced epithelial stem cell dysfunction.",

Retinal thinning has been reported in a variety of neurodegenerative conditions. Yet, studies of retinal involvement in ALS are sparse and results are heterogeneous. We studied retinal alterations in ALS using a systematic approach combining Optical Coherence Tomography (OCT), Diffusion Tensor Imaging (DTI) and clinical phenotyping. We hypothesized that selective changes of specific retinal layers may be a reflection of overall neurodegeneration as measured by DTI. Spectral domain OCT images were analyzed to calculate the average thickness of retinal layers in 71 ALS patients and 20 controls. In 30 patients, the region of interest (ROI) based fractional anisotrophy (FA) was measured in the corticospinal tract (CST), as this region is preferentially affected by motor neuron degeneration. Clinical data were collected for correlation analysis. Patients showed a significant thinning of the inner nuclear layer (INL; p\u00a0=\u00a00.04) and the retinal nerve fibre layer (RNFL; p\u00a0=\u00a00.004) compared to controls. We saw significant correlations between retinal thickness and FA values of the CST in patients (p\u00a0=\u00a00.005). No significant correlation between clinical parameters and retinal involvement was observed. Our study provides evidence for a retinal involvement in ALS. Interestingly, ALS patients show a reduction in FA of the CST, which is correlated to retinal thinning. We conclude that retinal involvement is in fact associated to overall neurodegeneration and may be regarded as a potential technical biomarker in ALS.",

The pigment neuromelanin is closely related to melanin and is mainly produced in specific neurons of the substantia nigra. Certain drugs and chemicals bind to melanin/neuromelanin and are retained in pigment cells for long periods. This specific retention is thought to protect the cells but also to serve as a depot that slowly releases accumulated compounds and may cause toxicity in the eye and skin. Moreover, neuromelanin and compounds with high neuromelanin affinity have been suggested to be implicated in the development of adverse drug reactions in the central nervous system (CNS) as well as in the etiology of Parkinson's disease (PD). Epidemiologic studies implicate the exposure to pesticides, metals, solvents and other chemicals as risk factors for PD. Neuromelanin interacts with several of these toxicants which may play a significant part in both the initiation and the progression of neurodegeneration. MPTP/MPP(+) that has been casually linked with parkinsonism has high affinity for neuromelanin, and the induced dopaminergic denervation correlates with the neuromelanin content in the cells. Recent studies have also reported that neuromelanin may interact with \u03b1-synuclein as well as activate microglia and dendritic cells. This review aims to provide an overview of melanin binding of drugs and other compounds, and possible toxicological implications, with particular focus on the CNS and its potential involvement in neurodegenerative disorders.",

We previously showed that the anti-amyotrophic lateral sclerosis (ALS) drug riluzole functions as a PKC inhibitor. Here, we examined the effects of riluzole on pathological changes in diabetic retinopathy. Pathological endpoints examined in vivo included the number of pericytes and integrity of retinal vessels in streptozotocin (STZ)-induced diabetic mice. In addition, PKC activation and the induction of monocyte chemotactic protein (MCP1) were assessed in diabetic mice and in human retinal pericytes exposed to advanced glycation end product (AGE) or modified low-density lipoprotein (mLDL). The diameter of retinal vessels and the number of pericytes were severely reduced, and the levels of MCP1 and PKC were increased in STZ-induced diabetic mice. Administration of riluzole reversed all of these changes. Furthermore, the increased expression of MCP1 in AGE- or mLDL-treated cultured retinal pericytes was inhibited by treatment with riluzole or the PKC inhibitor GF109203X. In silico modeling showed that riluzole fits well within the catalytic pocket of PKC. Taken together, our results demonstrate that riluzole attenuates both MCP1 induction and pericyte loss in diabetic retinopathy, likely through its direct inhibitory effect on PKC.",

Studies in pericyte-deficient transgenic mice with aberrant signaling between endothelial-derived platelet-derived growth factor BB (PDGF-BB) and platelet-derived growth factor receptor \u03b2 (PDGFR\u03b2) in pericytes have contributed to better understanding of the role of pericytes in the brain. Here, we studied Pdgfr\u03b2F7/F7 mice, which carry seven point mutations that disrupt PDGFR\u03b2 signaling causing loss of pericytes and vascular smooth muscle cells (VSMCs) in the developing brain. We asked whether these mice have a stable or progressive vascular phenotype after birth, and whether both pericyte and VSMCs populations are affected in the adult brain. We found an early and progressive region-dependent loss of brain pericytes, microvascular reductions and blood-brain barrier (BBB) breakdown, which were more pronounced in the cortex, hippocampus and striatum than in the thalamus, whereas VSMCs population remained unaffected at the time when pericyte loss was already established. For example, compared to age-matched controls, Pdgfr\u03b2F7/F7 mice between 4-6 and 36-48 weeks of age developed a region-dependent loss in pericyte coverage (22-46, 24-44 and 4-31%) and cell numbers (36-49, 34-64 and 11-36%), reduction in capillary length (20-39, 13-46 and 1-30%), and an increase in extravascular fibrinogen-derived deposits (3.4-5.2, 2.8-4.1 and 0-3.6-fold) demonstrating BBB breakdown in the cortex, hippocampus and thalamus, respectively. Capillary reductions and BBB breakdown correlated with loss of pericyte coverage. Our data suggest that Pdgfr\u03b2F7/F7 mice develop an aggressive and rapid vascular phenotype without appreciable early involvement of VSMCs, therefore providing a valuable model to study regional effects of pericyte loss on brain vascular and neuronal functions. This model could be a useful tool for future studies directed at understanding the role of pericytes in the pathogenesis of neurological disorders associated with pericyte loss such as vascular dementia, Alzheimer's disease, amyotrophic lateral sclerosis, stroke and human immunodeficiency virus-associated neurocognitive disorder.",

The macular ganglion cell complex (mGCC), peripapillary retinal nerve fiber layer (RNFL), refractive status, and ocular biometry were measured. The metrics of the mGCC and associated anatomical changes were the primary outcomes. Mann-Whitney U tests and chi-squared tests were used to compare variables between the two groups.ResultsA total of 41 eyes from 21 preterm children with ROP and 34 eyes from 17 full-term children were enrolled. ROP eyes had significantly thicker mGCC (P<0.001) with uneven distribution compared with full-term eyes. The RNFLs of ROP eyes were thicker in the temporal quadrants but thinner in the nasal quadrants (P=0.01 and.04, respectively). In addition, the ROP eyes had shallower anterior chamber depths (ACDs), thicker lenses, and higher degrees of refractive errors (all P<0.05) but similar axial lengths (ALs) (P=0.58) compared with full-term eyes.ConclusionsThe mGCC was thicker in children with ROP, and their inner retinal structures had a different distribution pattern than those in full-term children. The myopia of children with ROP was associated with the abnormal development of the anterior segment rather than long ALs. These alterations in inner retinal anatomy and optic components emphasize the importance of careful examinations to monitor the development of glaucoma or visual decline in children with ROP.",

Recently, three causative genes have been implicated in both ALS and glaucoma. However, it is still uncertain whether patients with ALS have neurodegeneration in their retinas. If so, retinal thickness measurements might be a useful biomarker for ALS progression. Previous work in this area has been inconclusive, as it has not taken into account the effect of ophthalmic diseases on retinal thinning. To determine whether there are differences in retinal neurons in ALS patients utilizing spectral-domain optical coherence tomography (SD-OCT). We tested the hypothesis that ALS patients exhibit retinal neurodegeneration that is not associated with ophthalmic diseases. Observational, comparative, cross-sectional study performed on patients recruited from the Duke University Medical Center ALS clinic. Patients underwent a comprehensive ophthalmologic examination to rule out ocular pathology. 21 patients met inclusion criteria. Two eyes with ocular pathology were excluded, leading to a total of 40 eyes of 21 patients included in the study. Retinal neurodegeneration was assessed by retinal nerve fiber layer (RNFL) thickness measurement using SD-OCT (Spectralis; Heidelberg Engineering). ALS disease severity, determined through the ALS Functional Rating Scale (ALSFRS-R); mean and six sector RNFL thickness values compared to age-adjusted values in the normative database provided by Heidelberg Engineering; RNFL thickness correlation with ALSFRS-R, ALSFRS-R progression rate, forced vital capacity (FVC), and visual acuity. ALSFRS-R mean score was 30+/-10. Mean RNFL thickness in ALS patients was 88.95 +/- 10.8 microns, significantly thinner than values in the normative database (95.81 +/- 0.8). These RNFL thickness values did not demonstrate correlation to ALSFRS-R score, ALSFRS-R progression rate, FVC, intraocular pressure, or visual acuity. Using SD-OCT, our study shows that ALS patients without ocular pathology exhibit thinned retinal layers. Future studies are warranted to clarify the clinical relationship between retinal thinning and motor neuron loss in ALS.",

Exploring the evidence for common pathogenesis of these two progressive neurological disorders may assist in understanding the mechanism and searching for new treatment. Retinal nerve fiber layer (RNFL) defect and corresponding visual field (VF) impairment are well known neuropathy signs in glaucoma. In our study, thickness of certain retinal layer in ALS patients was analyzed to detect ganglion cell's soma and axon, and for first time visual field was examined for ALS. The correlation of retinal involvement and ALS progression were also investigated. The results were compared with those of POAG.

However, these cells can be differentiated into neuronal cells. Here, we report that this cell line expressed certain markers specific to retinal ganglion cells such as Rbpms, Brn3b (Pou4f2), Brn3c (Pou4f3), Thy1 and \u03b3-synuclein (Sncg), and some other markers of neuronal cells (beta-III tubulin, NeuN and MAP2). These cells also expressed Opn1mw, a cone-specific marker and nestin, a marker for neural precursor cells. Two glaucoma-associated mutants of OPTN, E50K and M98K, but not an amyotrophic lateral sclerosis-associated mutant, E478G, induced cell death selectively in 661W cells. However, in a motor neuron cell line, NSC34, E478G mutant of OPTN but not E50K and M98K induced cell death. We conclude that 661W is a retinal ganglion precursor-like cell line, which shows properties of both retinal ganglion and photoreceptor cells. We suggest that these cells could be utilized for exploring the mechanisms of cell death induction and cytoprotection relevant for glaucoma pathogenesis.

A direct assessment of brain SBVs in vivo is currently not feasible. Retinal vessels are considered a \"mirror\" of brain SBVs. In this study, we used optic coherence tomography (OCT)-based measurements to detect changes in retinal blood vessels of ALS patients compared to those of healthy controls. We analysed Spectralis-OCT images of 34 ALS patients and 20 HCs. The inner wall thickness (IWT), outer wall thickness (OWT), and lumen diameter (LD) of retinal vessels were assessed using intensity-based measurements. In addition, the different retinal layers were analysed using automated segmentation software. The correlations between the various retinal layers and clinical parameters [e.g., disease duration and revised ALS functional rating scale (ALS-FRS-R)] were examined. The OWT of retinal vessels was higher in ALS patients than in HCs (p\u00a0=\u00a00.04). There were no differences in the IWT, LD. ALS patients showed a thinning of the outer nuclear layer (ONL) compared to HCs (median 1.63 vs. 1.77, p\u00a0=\u00a00.002). The whole retinal thickness negatively correlated with the ALS-FRS scale (r\u00a0=\u00a00.3, p\u00a0=\u00a00.03). Our study reports retinal vessel pathology in ALS patients. These changes may be related to those observed in SBVs in skin and muscle biopsies. Furthermore, we report a thinning of the ONL in ALS, revealing a possible affection of rods and cones function in ALS.",

Certain mutations in OPTN (gene OPTN) are associated with primary open angle glaucoma, a leading cause of irreversible blindness, and amyotrophic lateral sclerosis, a fatal motor neuron disease. Glaucoma-associated mutations of OPTN are mostly missense mutations. OPTN mediates its functions by interacting with various proteins and altered interactions of OPTN mutants with various proteins primarily contribute to functional defects. It interacts with Rab8, myosin VI, Huntigtin, TBC1D17, and transferrin receptor to mediate various membrane vesicle trafficking pathways. It is an autophagy receptor that mediates cargo-selective as well as non-selective autophagy. Glaucoma-associated mutants of OPTN, E50K, and M98K, cause defective vesicle trafficking, autophagy, and signaling that contribute to death of retinal ganglion cells (RGCs). Transgenic mice expressing E50K-OPTN show loss of RGCs and persistent reactive gliosis. TBK1 protein kinase, which mediates E50K-OPTN and M98K-OPTN induced cell death, is emerging as a potential drug target. Autoimmunity has been implicated in glaucoma but involvement of OPTN or its mutants in autoimmnity has not been explored. In this review, we highlight the main functions of OPTN and how glaucoma-associated mutants alter these functions. We also discuss some of the controversies, such as the role of OPTN in signaling to transcription factor NF-\u03baB, interferon signaling, and use of RGC-5 cell line as a cell culture model.",

Optical coherence tomography (OCT) is a method that can be used in clinical practice to detect and quantify the structural correlates of these visual symptoms in neurological disorders. OCT is a non-invasive imaging technique, based on interferometry, which can create high-resolution images of the retina and measure the thickness and volume of the different retinal layers. The combined ganglion cell- and inner plexiform layer (GCIPL) and the peripapillary retinal nerve fibre layer (pRNFL) are of particular interest in the field of neurological disorders, since they contain the neuronal bodies (ganglion cells) and their axons that form the optic nerve. In acute optic neuritis (ON), initial swelling of the pRNFL can be detected by OCT and this may contribute to the diagnosis and differential diagnosis of ON; moreover, the extent of the GCIPL-thinning within the first 4\u00a0weeks after an acute ON can contribute to the prediction of the long-term visual recovery. However, the role of OCT in the field of multiple sclerosis (MS) is not restricted in patients with ON, since even eyes without an ON-history show mild thinning of the pRNFL and GCIPL. This thinning seems to be associated with neurodegenerative processes in the entire CNS. Several studies showed correlations between these OCT-parameters and a higher risk of clinical deterioration (disability progression), cognitive deficits and disease activity in patients with MS. However, it is often still unclear how these correlations can be useful in the management of the individual patient. In recent years, OCT has been applied to a greater extent to neurodegenerative diseases, such as Parkinson's disease, amyotrophic lateral sclerosis (ALS) and various forms of dementia. However, routine clinical use is still further away than for inflammatory CNS diseases, since the role of OCT in the diagnosis, differential diagnosis and prediction of the clinical course of neurodegenerative diseases is still unclear. This review article offers a summary of the available study results on OCT parameters and their role in inflammatory, degenerative and tumorous diseases of the central nervous system (CNS). Inflammatorische, degenerative und tumor\u00f6se Erkrankungen des zentralen Nervensystems (ZNS) gehen h\u00e4ufig mit Ver\u00e4nderungen am Augenhintergrund und Sehst\u00f6rungen einher.

Das auf Interferometrie beruhende, nicht invasive Verfahren ist in der Lage, hochaufgel\u00f6ste Volumenaufnahmen der Retina aufzunehmen und die Dicke bzw. das Volumen einzelner Schichten der Netzhaut zu messen. Insbesondere die pRNFL (peripapill\u00e4re retinale Nervenfaserschicht) und GCIPL (Ganglienzellschicht und innere plexiforme Schicht zusammen) sind in der Neurologie von gro\u00dfem Interesse, da sie Axone und zugeh\u00f6rige Nervenzellen enthalten, die im weiteren Verlauf den Sehnerv bilden. Bei einer akuten Optikusneuritis (ON) kann eine initiale Schwellung der pRNFL zur Diagnose und Differenzialdiagnose der ON und eine Verd\u00fcnnung der GCIPL w\u00e4hrend der ersten 4 Wochen zur Prognose der Visuserholung beitragen. Bei der multiplen Sklerose (MS) ist die Rolle der OCT nicht nur in Zusammenhang mit der ON zu sehen. Auch MS-Augen ohne ON zeigen eine Verd\u00fcnnung der pRNFL und GCIPL, die mit neurodegenerativen Prozessen im gesamten ZNS korreliert. Mehrere Studien haben Korrelationen zwischen diesen OCT-Parametern und dem Risiko f\u00fcr eine klinische Verschlechterung (Behinderungsprogression), kognitive Defizite, aber auch Krankheitsaktivit\u00e4t bei MS gezeigt, wobei es h\u00e4ufig noch unklar ist, wie dieser Zusammenhang in der Behandlung des individuellen Patienten nutzbar gemacht werden kann.

The Ran-binding protein 2 (Ranbp2) controls rate-limiting steps of nucleocytoplasmic transport. Mice with Ranbp2 loss in Thy1+-motoneurons develop cardinal ALS-like motor traits, but the impairments in RGNs and the degree of dysfunctional consonance between RGNs and motoneurons caused by Ranbp2 loss are unknown. This will help to understand the role of nucleocytoplasmic transport in the differential vulnerability of neuronal cell types to ALS and to uncover non-motor endophenotypes with pathognomonic signs of ALS. Here, we ascertain Ranbp2's function and endophenotypes in RGNs of an ALS-like mouse model lacking Ranbp2 in motoneurons and RGNs. Thy1+-RGNs lacking Ranbp2 shared with motoneurons the dysregulation of nucleocytoplasmic transport. RGN abnormalities were comprised morphologically by soma hypertrophy and optic nerve axonopathy and physiologically by a delay of the visual pathway's evoked potentials. Whole-transcriptome analysis showed restricted transcriptional changes in optic nerves that were distinct from those found in sciatic nerves. Specifically, the level and nucleocytoplasmic partition of the anti-apoptotic and novel substrate of Ranbp2, Pttg1/securin, were dysregulated. Further, acetyl-CoA carboxylase 1, which modulates de novo synthesis of fatty acids and T-cell immunity, showed the highest up-regulation (35-fold). This effect was reflected by the activation of ramified CD11b+ and CD45+-microglia, increase of F4\\80+-microglia and a shift from pseudopodial/lamellipodial to amoeboidal F4\\80+-microglia intermingled between RGNs of naive mice. Further, there was the intracellular sequestration in RGNs of metalloproteinase-28, which regulates macrophage recruitment and polarization in inflammation. Hence, Ranbp2 genetic insults in RGNs and motoneurons trigger distinct paracrine signaling likely by the dysregulation of nucleocytoplasmic transport of neuronal-type selective substrates. Immune-modulators underpinning RGN-to-microglial signaling are regulated by Ranbp2, and this neuronal-glial system manifests endophenotypes that are likely useful in the prognosis and diagnosis of motoneuron diseases, such as ALS.",

Patients lose the ability to talk and swallow and rely on parenteral nutrition and assisted ventilation to survive. The degeneration caused by ALS is progressive and irreversible. In addition to the autonomous mechanism of neuronal cell death, non-autonomous mechanisms have been proved to be toxic for motor neurons, such as the activation of astrocytes and microglia.

Several such proteins, e.g. TDP-43, aggregate and are toxic when expressed in yeast. Deletion of the ATXN2 ortholog, PBP1, reduces yeast TDP-43 toxicity, which led to identification of ATXN2 as an amyotrophic lateral sclerosis (ALS) risk factor and therapeutic target. Likewise, new yeast neurodegenerative disease models could facilitate identification of other risk factors and targets. Mutations in SS18L1, encoding the calcium-responsive transactivator (CREST) chromatin-remodeling protein, are associated with ALS. We show that CREST is toxic in yeast and forms nuclear and occasionally cytoplasmic foci that stain with Thioflavin-T, a dye indicative of amyloid-like protein. Like the yeast chromatin-remodeling factor SWI1, CREST inhibits silencing of FLO genes. Toxicity of CREST is enhanced by the [PIN+] prion and reduced by deletion of the HSP104 chaperone required for the propagation of many yeast prions. Likewise, deletion of PBP1 reduced CREST toxicity and aggregation. In accord with the yeast data, we show that the Drosophila ortholog of human ATXN2, dAtx2, is a potent enhancer of CREST toxicity. Downregulation of dAtx2 in flies overexpressing CREST in retinal ganglion cells was sufficient to largely rescue the severe degenerative phenotype induced by human CREST. Overexpression caused considerable co-localization of CREST and PBP1/ATXN2 in cytoplasmic foci in both yeast and mammalian cells. Thus, co-aggregation of CREST and PBP1/ATXN2 may serve as one of the mechanisms of PBP1/ATXN2-mediated toxicity. These results extend the spectrum of ALS associated proteins whose toxicity is regulated by PBP1/ATXN2, suggesting that therapies targeting ATXN2 may be effective for a wide range of neurodegenerative diseases.",

SMA is caused by insufficient levels of the Survival Motor Neuron (SMN) protein, which operates as part of the multiprotein SMN complex that includes the DEAD-box RNA helicase Gemin3/DDX20/DP103. C9orf72, SOD1, TDP-43 and FUS are ranked as the four major genes causing familial ALS. Accumulating evidence has revealed a surprising molecular overlap between SMA and ALS. Here, we ask the question of whether Drosophila can also be exploited to study shared pathogenic pathways. Focusing on motor behaviour, muscle mass and survival, we show that disruption of either TBPH/TDP-43 or Caz/FUS enhance defects associated with Gemin3 loss-of-function. Gemin3-associated neuromuscular junction overgrowth was however suppressed. Sod1 depletion had a modifying effect in late adulthood. We also show that Gemin3 self-interacts and Gem3\u0394N, a helicase domain deletion mutant, retains the ability to interact with its wild-type counterpart. Importantly, mutant:wild-type dimers are favoured more than wild-type:wild-type dimers. In addition to reinforcing the link between SMA and ALS, further exploration of mechanistic overlaps is now possible in a genetically tractable model organism. Notably, Gemin3 can be elevated to a candidate for modifying motor neuron degeneration.",

Rhodopsin is a G-protein coupled receptor found in the rod cells of the retina. As a biomarker associated with retinal thinning and degeneration, it bears potential in the early detection and monitoring of several neurodegenerative diseases. In this review article, we summarize the findings of correlations between rhodopsin and several neurodegenerative disorders as well as the potential of a novel technique, cSLO, in the quantification of rhodopsin.",

The authors included 88 refractive lens exchange and cataract surgeries, with AcrySof IQ PanOptix implant (Alcon Laboratories, Inc.). All eyes were divided into three groups based on axial length (AL), group 1: <22 mm (14 eyes), group 2: 22-24.5 mm (68 eyes) and group 3: >24.5 mm (6 eyes). The refractive prediction error (RPE) and mean absolute error (MAE) were calculated for 5 different formulas: SRK/T, Hoffer Q, Holladay 1, Haigis and Barrett Universal II. For eyes with the AL between 22 mm and 24.5 mm the greatest percentage of eyes with RPEs within \u00b10.25 D was 32.4% for Haigis formula, followed by Barrett Universal II, Hoffer Q and Holladay 1 with 29.4%. The percentage of eyes with RPEs within \u00b10.50 D was 100% only for Barrett Universal II and Holladay 1, 94.1% for SRK/T and 91.2% for Haigis and Hoffer Q. The first and third group with AL <22 and >24.5 mm were too small to have statistical significance due to the reluctancy to use multifocal IOLs on extreme ALs. ANOVA test showed no statistical difference (P=0.166) between the RPEs measured for each formula in this cohort. This study showed no statistical difference between formulas for this trifocal lens implant. There was a tendency for the RPE to be within \u00b10.25 D for most of the eyes with the Haigis formula, and within \u00b10.50 D for all the eyes with the Barrett Universal II formula in the group with the AL between 22 and 24.5 mm.",

Previous work has shown diverse mechanisms leading to BMAA-induced degeneration; however, the underlying mechanisms of toxicity affecting retina cells are not fully elucidated. We here show that BMAA treatment of rat retina neurons in vitro induced nuclear fragmentation and cell death in both photoreceptors (PHRs) and amacrine neurons, provoking mitochondrial membrane depolarization. Pretreatment with the N-Methyl-D-aspartate (NMDA) receptor antagonist MK-801 prevented BMAA-induced death of amacrine neurons, but not that of PHRs, implying activation of NMDA receptors participated only in amacrine cell death. Noteworthy, BMAA stimulated a selective axonal outgrowth in amacrine neurons, simultaneously promoting growth cone destabilization. BMAA partially decreased the viability of M\u00fcller glial cells (MGC), the main glial cell type in the retina, induced marked alterations in their actin cytoskeleton and impaired their capacity to protect retinal neurons. BMAA also induced cell death and promoted axonal outgrowth in differentiated rat pheochromocytoma (PC12) cells, implying these effects were not limited to amacrine neurons. These results suggest that BMAA is toxic for retina neurons and MGC and point to the involvement of NMDA receptors in amacrine cell death, providing new insight into the mechanisms involved in BMAA neurotoxic effects in the retina.",

Postmortem eyes from 10 patients with ALS were sectioned and compared with 10 age-matched controls. Retinal sections were evaluated with periodic acid Schiff and phosphorylated (P-NF) and nonphosphorylated (NP-NF) forms of neurofilament with SMI 31 and 32 antibodies. Spheroids identified in the retinal nerve fiber layer were counted and their overall density was calculated in central, peripheral, and peripapillary regions. P-NF intensity was quantified. Morphometric features of ALS cases were compared with age-matched controls using the exact Wilcoxon matched-pairs signed-rank test. Distinct periodic acid Schiff-positive round profiles were identified in the retinal nerve fiber layer of patients with ALS and were most commonly observed in the peripapillary and peripheral retina. The density of periodic acid Schiff-positive spheroids was significantly greater in patients with ALS compared with controls (P = 0.027), with increased density in the peripapillary region (P = 0.047). Spheroids positive for P-NF and NP-NF were detected. P-NF-positive spheroid density was significantly increased in patients with ALS (P = 0.004), while the density of NP-NF spheroids did not differ significantly between ALS and control groups (P > 0.05). P-NF immunoreactivity in the retinal nerve fiber layer was significantly greater in patients with ALS than in controls (P = 0.002). Retinal spheroids and axon pathology discovered in patients with ALS, similar to hallmark findings in spinal cord motor neurons, point to disrupted axon transport as a shared pathogenesis. Retinal manifestations detected in ALS suggest a novel biomarker detectable by noninvasive retinal imaging to help to diagnose and monitor ALS disease.",

In this pathology, both neurons and glial cells are affected. However, few studies have analyzed retinal microglia in ALS models. In this study, we quantified the signs of microglial activation and the number of retinal ganglion cells (RGCs) in an SOD1G93A transgenic mouse model at 120 days (advanced stage of the disease) in retinal whole-mounts. For SOD1G93A animals (compared to the wild-type), we found, in microglial cells, (i) a significant increase in the area occupied by each microglial cell in the total area of the retina; (ii) a significant increase in the arbor area in the outer plexiform layer (OPL) inferior sector; (iii) the presence of cells with retracted processes; (iv) areas of cell groupings in some sectors; (v) no significant increase in the number of microglial cells; (vi) the expression of IFN-\u03b3 and IL-1\u03b2; and (vii) the non-expression of IL-10 and arginase-I. For the RGCs, we found a decrease in their number. In conclusion, in the SOD1G93A model (at 120 days), retinal microglial activation occurred, taking a pro-inflammatory phenotype M1, which affected the OPL and inner retinal layers and could be related to RGC loss.",
        "34023378": "ID: 34023378\nTitle: Human primary retinal cells as an in-vitro model for investigating defective signalling caused by OPTN mutants associated with glaucoma.\nAbstract: Studies carried out on the pathogenesis of glaucoma using murine cell lines and animal models require to be validated in human cells. Therefore, we explored the possibility of using human primary retinal cells (hPRCs) in culture as a model for molecular studies and testing of potential therapeutic drugs. For this purpose, central retinal tissue, obtained from the enucleated eyes of patients with anterior staphyloma, was digested with trypsin and grown in a medium containing supplements (basic fibroblast growth factor and fetal bovine serum). hPRCs at passage 1 and 2, show expression of either GFAP, a glial cell marker, or \u03b2-III tubulin, a retinal ganglion cell (RGC)-specific marker. But at passages 3-5 nearly all of hPRCs express several RGC-specific markers (Brn3 proteins, Thy-1, \u03b2-III tubulin, RBPMS and NeuN) but not GFAP. Expression of these markers indicated that these cells may have functional properties of RGCs. As RGCs are sensitive to glaucoma-associated mutants of OPTN, we analysed the survival of hPRCs upon overexpression of OPTN mutants. Glaucoma-associated mutants, E50K-OPTN and M98K-OPTN, induced significantly higher cell death in hPRCs compared to WT-OPTN, whereas an amyotrophic lateral sclerosis-associated mutant, E478G-OPTN, did not. TBK1 inhibitor Amlexanox protected hPRCs from E50K-OPTN and M98K-OPTN induced cell death. M98K-OPTN induced cell death was suppressed by inhibitors of CaMKK\u03b2 and AMPK in hPRCs as well as in 661W, a mouse cell line that expresses several markers of RGCs and RGC precursor cells. Our results suggest that hPRCs under appropriate culture condition show RGC-like properties. These cells can be used to explore the molecular mechanisms of cell death relevant for glaucoma pathogenesis and for testing of cytoprotective compounds.",

Spectral domain optical coherence tomography (OCT) allows for detailed evaluation of the retina and the optic nerve. OCT can non-invasively document changes in single retina layer thickness and structure due to neuronal and retinal glial cells (RGC) modifications in systemic and local inflammatory and neurodegenerative diseases. These can include evaluation of retinal nerve fibre layer and ganglion cell complex, hyper-reflective retinal spots (HRS, sign of activated microglial cells in the retina), subfoveal neuroretinal detachment, disorganization of the inner retinal layers (DRIL), thickness and integrity of the outer retinal layers and choroidal thickness. This review paper will report the most recent data on the use of OCT as a non invasive imaging biomarker for evaluation of the most common systemic neuroinflammatory and neurodegenerative/neurocognitive disorders in the adults and in paediatric population. In the adult population the main focus will be on diabetes mellitus, multiple sclerosis, optic neuromyelitis, neuromyelitis optica spectrum disorders, longitudinal extensive transverse myelitis, Alzheimer and Parkinson diseases, Amyotrophic lateral sclerosis, Huntington's disease and schizophrenia.

The aim of the present study was, therefore, to systematically analyze retinal layers and vascularization by means of spectral-domain (SD-OCT) and optical coherence tomography angiography (OCT-A) in ALS patients. We enrolled 48 ALS patients and 45 healthy controls. ALS patients were divided into three groups: slow progressors (n = 10), intermediate progressors (n = 24) and fast progressors (n = 14), according to the disease progression rate. For SD-OCT, we evaluated the Subfoveal choroidal thickness (SFCT), ganglion cell complex (GCC) and retinal nerve fiber layer (RNFL). Regarding the OCT-A, we assessed the vessel density (VD) in superficial and deep capillary plexuses, radial peripapillary capillary plexus, choriocapillary and the foveal avascular zone (FAZ) area. SD-OCT exam did not show any significant differences in GCC and RNFL thickness between patients and controls and among the three ALS groups. The SFCT was statistically greater in patients compared with controls (357.95 \u00b1 55.15 \u00b5m vs. 301.3 \u00b1 55.80 \u00b5m, p < 0.001); interestingly, the SFCT was thicker in patients with slow and intermediate disease progression than in those with fast disease progression (394.45 \u00b1 53.73 \u00b5m vs. 393.09 \u00b1 42.17 \u00b5m vs. 267.71 \u00b1 56.24 \u00b5m, p < 0.001). OCT-A did not reveal any significant results. Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-r) and disease duration did not correlate with any of the OCT parameters, except for SFCT with ALSFRS-r (r = 0.753, p = 0.024).

Here, we report the use of cryoelectron microscopy (cryo-EM) to define the composition of a raw bovine retinal pigment epithelium (RPE) lysate. From this sample, we simultaneously identify and solve cryo-EM structures of seven different RPE enzymes whose functions affect neurotransmitter recycling, iron metabolism, gluconeogenesis, glycolysis, axonal development, and energy homeostasis. Interestingly, dysfunction of these important proteins has been directly linked to several neurodegenerative disorders, including Huntington's disease, amyotrophic lateral sclerosis (ALS), Parkinson's disease, Alzheimer's disease, and schizophrenia.

        "36714840": "ID: 36714840\nTitle: Vascular endothelial growth factor from retinal pigment epithelium is essential in choriocapillaris and axial length maintenance.\nAbstract: Myopia, which prevalence is rapidly increasing, causes visual impairment; however, the onset mechanism of pathological axial length (AL) elongation remains unclear. A highly vascularized choroid between the retinal pigment epithelium (RPE) and sclera not only maintains physiological activities, but also contributes to ocular development and growth regulation. Vascular endothelial growth factor (VEGF) secreted from the RPE to the choroid is essential for retinal function and maintenance of the choriocapillaris. Herein, we demonstrated that the loss of VEGF secreted from the RPE caused abnormal choriocapillaris development and AL elongation, with features similar to those of the lens-induced myopia (LIM) mouse model, whereas VEGF overexpression by knocking-out von Hippel-Lindau (VHL) specific to the RPE expands the choriocapillaris and shortens the AL. Additionally, LDL Receptor Related Protein 2 (LRP2) deletion in the RPE downregulated VEGF expression and leads to pathological AL elongation. Furthermore, high-myopia patients without choriocapillaris demonstrated longer ALs than did those with preserved choriocapillaris. These results suggest that physiological secretion of VEGF from the RPE is required for proper AL development by maintaining the choriocapillaris. The pinpoint application of VEGF to the choriocapillaris may become a potential intervention for the prevention and treatment of axial myopia progression.",

Kynurenines display a wide range of biological actions (which are often contrasting) such as cytotoxic/cytoprotective, oxidant/antioxidant or pro-/anti-inflammatory. The net effect depends on their local concentration, cellular environment, as well as a complex positive and negative feedback loops. The imbalance between beneficial and harmful kynurenines was implicated in the pathogenesis of various neurodegenerative disorders, psychiatric illnesses and metabolic disorders, including diabetes mellitus (DM). Despite available therapies, DM may lead to serious macro- and microvascular complications including cardio- and cerebrovascular disease, peripheral vascular disease, chronic renal disease, diabetic retinopathy, autonomic neuropathy or cognitive impairment. It is well established that low-grade inflammation, which often coincides with DM, can affect the function of KP and, conversely, that kynurenines may modulate the immune response. This review provides a detailed summary of findings concerning the status of the Trp-KYN pathway in DM based on available animal, human and microbiome studies. We highlight the importance of the molecular interplay between the deranged (functionally and qualitatively) conversion of Trp to kynurenines in the development of DM and insulin resistance. The Trp-KYN pathway emerges as a novel target in the search for preventive and therapeutic interventions in DM.",

Although many potential mechanisms have been proposed, the pathophysiology of the disease remains unknown. Currently available treatments can only delay the progression of the disease and prolong life expectancy by a few months. There is still no definitive cure for ALS, and the development of new treatments is limited by a lack of understanding of the underlying biological processes that trigger and promote neurodegeneration. Several scientific results suggest a neurovascular impairment in ALS providing perspectives for the development of new biomarkers and treatments. In this article, we performed a systematic review using PRISMA guidelines including PubMed, EmBase, GoogleScholar, and Web of Science Core Collection to analyze the scientific literature published between 2000 and 2021 discussing the neurocardiovascular involvement and ophthalmologic abnormalities in ALS. In total, 122 articles were included to establish this systematic review. Indeed, microvascular pathology seems to be involved in ALS, affecting all the neurovascular unit components. Retinal changes have also been recently highlighted without significant alteration of the visual pathways. Despite the peripheral location of the retina, it is considered as an extension of the central nervous system (CNS) as it displays similarities to the brain, the inner blood-retinal barrier, and the blood-brain barrier. This suggests that the eye could be considered as a 'window' into the brain in many CNS disorders. Thus, studying ocular manifestations of brain pathologies seems very promising in understanding neurodegenerative disorders, mainly ALS. Optical coherence tomography angiography (OCT-A) could therefore be a powerful approach for exploration of retinal microvascularization allowing to obtain new diagnostic and prognostic biomarkers of ALS.",

Outcomes were analyzed with Comprehensive Meta-Analysis V2 software, random effects models, and Hedge's G. Effects were examined at 0-4\u00a0months, up to 6\u00a0months, and\u00a0>\u00a06\u00a0months. Pre-specified sensitivity analyses were performed for 1) controlled trials vs. all studies and 2) ALSFRS-R bulbar, respiratory, and motor subscales. Heterogeneity of pooled outcomes was computed with the I2 statistic. 16 studies and seven functional outcomes met inclusion for the meta-analysis. Of the outcomes explored, the ALSFRS-R demonstrated a favorable summary effect size and had acceptable heterogeneity and dispersion. While FIM scores demonstrated a favorable summary effect size, heterogeneity limited interpretations. Other outcomes did not demonstrate a favorable summary effect size and/or could not be reported due to few studies reporting outcomes. This study provides inconclusive guidance regarding exercise regimens to maintain function and quality of life in people with ALS due to study limitations (e.g., small sample size, high attrition rate, heterogeneity in methods and participants, etc.).

Meta-analyses revealed significant reductions in sleep efficiency, total sleep time, N2%, slow wave sleep percentage, minimum SpO2, and mean SpO2, and increases in wake time after sleep onset and N1%, sleep latency, rapid eye movement sleep latency, time spent with SpO2 < 90%, oxygen desaturation index, and apnea hypopnea index in ALS patients compared with controls. Sensitivity analyses showed that some heterogeneity was explained by excluding patients taking medications impacting sleep, whether studies employed an adaptation night, and the use of different PSG scoring rules. Significant polysomnographic abnormalities are present in ALS. Our findings underscore the need for a comprehensive PSG assessment of sleep changes in ALS patients. When performing PSG examinations in ALS, whether the patients are taking medication impacting sleep and the scoring system used should be considered.",

The OCT parameters of macular retinal thickness (MRT) and ganglion cell-inner plexiform layer (GCIPL) thicknesses were evaluated between diabetic and normal eyes. The receiver operating characteristics (ROC) curve was generated to evaluate the discrimination power of early diabetes. Correlation and multiple regression analysis were performed between ophthalmological parameters and T2DM-related demographic and anthropometric variables, and serum biomarkers and homeostasis model assessment of insulin resistance (HOMA-IR) scores. MRT and GCIPL thicknesses showed significant thinning in patients, especially in inferotemporal area. High body mass index (BMI) correlated with decreased GCIPL thicknesses and elevated intraocular pressure (IOP). A negative correlation between waist-to-hip circumference ratio (WHR) and GCIPL thicknesses was also found. High-density lipoprotein (HDL) and fasting C-peptide (CP0) were associated with GCIPL thickness but only in inferotemporal region (r = 0.20, p = 0.04; r = -0.20, p = 0.05, respectively). Multiple regression analysis showed that increased HOMA-IR scores independently predicted both average (\u03b2 = -0.30, p = 0.05) and inferotemporal (\u03b2 = -0.34, p = 0.03) GCIPL thinning. Retinal thinning in early T2DM was associated with obesity-related metabolic disorders. IR as an independent risk factor for retinal neurodegeneration may increase the risk of developing glaucoma.",

Moreover, whether retinal atrophy has a clinical (diagnostic and prognostic) value in these diseases remains unclear. To add light on the pathological significance and clinical value of retinal atrophy in patients with amyotrophic lateral sclerosis (ALS) and Kennedy's disease (KD). Thirty-five ALS, thirty-seven KD, and forty-nine age-matched healthy controls (HC) were included in a one-year longitudinal study. Spectrum-domain optical coherence tomography (OCT) was performed at study entry (T0) and after 12\u00a0months (T1). Disease duration and functional rating scale (FRS) for ALS and KD patients were correlated to retinal thicknesses. Compared to HC, peripapillary retinal nerve fiber layer (pRNFL) thickness was significantly thinner in both ALS (p\u2009=\u20090.034) and KD (p\u2009=\u20090.003). pRNFL was thinner in KD compared to ALS, but the difference was not significant. In KD, pRNFL atrophy significantly correlated with both disease severity (r\u2009=\u20090.296, p\u2009=\u20090.035) and disease duration (r\u2009=\u2009-\u20090.308, p\u2009=\u20090.013) while no significant correlation was found in ALS (disease severity: r\u2009=\u20090.147, p\u2009=\u20090.238; disease duration: r\u2009=\u2009-\u20090.093, p\u2009=\u20090.459). During the follow-up, pRNFL thickness remained stable in KD while significantly decreased in ALS (p\u2009=\u20090.043). Our study provides evidence of retinal atrophy in both ALS and KD and suggests that retinal thinning is a primary local phenomenon in motoneuron diseases. The clinical value of pRNFL atrophy in KD is worthy of further investigation.",

The study reported here sought to obtain insights into the temporal profiles of gene expression changes in Bmp2, as well as those of two closely related genes, the inhibitor of DNA binding 3 (Id3) and Noggin (Nog), both during myopia induction and when the CL treatment was terminated to allow recovery from induced myopia. To induce myopia, 2-week-old pigmented guinea pigs (New Zealand strain, n = 8) wore monocular -10 diopter (D) rigid gas-permeable (RGP) CLs for one week, while the other eye served as a control. Ocular measurements were made at baseline, 3 days, and 7 days after the initiation of CL wear, with treatment then being terminated and additional measurements being made after a further 3 days, 1 week, and 2 weeks. Spherical equivalent refractive errors (SERs), axial length (AL), choroidal thickness (ChT), and scleral thickness (ScT) data were collected using retinoscopy, optical biometry (Lenstar), and spectral domain optical coherence tomography (SD-OCT), respectively. RPE samples were collected from both eyes of the guinea pigs after either 1 day or 1 week of CL wear or 1 day or 2 weeks after its termination, and RNA was subsequently isolated and subjected to quantitative real-time PCR (qRT-PCR) analyses, targeting the Bmp2, Id3, and Nog genes. Mean interocular differences (treated-control) in AL and SER were significantly different from baseline after 3 and 7 days of CL wear, consistent with induced myopia (p < 0.001 for all cases). Termination of CL wear resulted in the normalization (i.e., recovery) of the ALs and SERs of the treated eyes within 7 days, and the earlier significant ChT thinning with CL wear (p = 0004, day 7) was replaced by rapid thickening, which remained significant on day 7 (p = 0.009) but had normalized by day 14. The ChT changes were much smaller in magnitude than the AL changes in both phases. Interocular differences in the ScT showed no significant changes. The Bmp2 and Id3 genes were both significantly downregulated with CL wear, after 1 day (p = 0.012 and 0.016) and 7 days (p = 0.002 and 0.005), while Bmp2 gene expression increased and Nog gene expression decreased after the termination of CL wear, albeit transiently, which was significant on 1 day (p = 0.004 and 0.04) but not 2 weeks later. No change in Id3 gene expression was observed over the latter period. Conclusions: The above patterns of myopia induction and recovery validate this negative RGP-CL model as an alternative to traditional spectacle lens models for guinea pigs. The defocus-driven, sign-dependent changes in the expression of the Bmp2 gene in guinea pig RPE are consistent with observations in chicks and demonstrate the important role of BMP2 in eye growth regulation.",

A reduction in retinal thickness is an early indicator of diabetic retinopathy (DR), with progressive loss of neuroglia corresponding to DR severity. The brain undergoes similar pathophysiological events as the retina, which contribute to T2D-related cognitive decline. This study explored the relationship between retinal thinning and cognitive decline in the LepR db/db model of T2D. Diabetic db/db and non-diabetic db/+ mice aged 14 and 28 weeks underwent cognitive testing in short and long-term memory domains and in vivo retinal imaging using optical coherence tomography (OCT), followed by plasma metabolic measures and ex vivo quantification of neuroinflammation, oxidative stress and microvascular leakage. At 28 weeks, mice exhibited retinal thinning in the ganglion cell complex and inner nuclear layer, concomitant with diabetic insulin resistance, memory deficits, increased expression of inflammation markers and cerebrovascular leakage. Interestingly, alterations in retinal thickness at both experimental timepoints were correlated with cognitive decline and elevated immune response in the brain and retina. These results suggest that changes in retinal thickness quantified with in vivo OCT imaging may be an indicator of diabetic cognitive dysfunction and neuroinflammation.",

Oculomics has emerged as a field that utilizes ocular imaging biomarkers to provide insights into systemic diseases. Advances in diagnostic and imaging technologies including electroretinography, optical coherence tomography (OCT), confocal scanning laser ophthalmoscopy, fluorescence lifetime imaging ophthalmoscopy, and OCT angiography have revolutionized the ability to understand systemic diseases and even detect them earlier than clinical manifestations for earlier intervention. With the advent of increasingly large ophthalmic imaging datasets, machine learning models can be integrated into these ocular imaging biomarkers to provide further insights and prognostic predictions of neurodegenerative disease. In this manuscript, we review the use of ophthalmic imaging to provide insights into neurodegenerative diseases including Alzheimer Disease, Parkinson Disease, Amyotrophic Lateral Sclerosis, and Huntington Disease. We discuss recent advances in ophthalmic technology including eye-tracking technology and integration of artificial intelligence techniques to further provide insights into these neurodegenerative diseases. Ultimately, oculomics opens the opportunity to detect and monitor systemic diseases at a higher acuity. Thus, earlier detection of systemic diseases may allow for timely intervention for improving the quality of life in patients with neurodegenerative disease.",

DR is also a neurodegenerative disease. Patients with hyperglycemia, hyperlipidemia, and hypertension are vulnerable to retinopathy development. While the roles of blood glucose and blood pressure in the development of retinopathy have been extensively studied, the relationship between body fat and DR pathogenesis and the impact of lipid-reducing drugs on DR has just emerged as a research hotspot in DR study. We aim to visualize the contributions and cooperation of reporters, organizations, and nations, in addition to the research hotspots and trends in DR-related lipid research from 1993 to 2023, by bibliometric analysis. We extracted all publications about DR-related lipid research from 1993 to 2023 from the Web of Science Core Collection, and bibliometric features were studied using VOSviewer and the CiteSpace program. 1402 documents were retrieved. The number of studies has risen consistently for three decades, from an average of 16.8/year in the 1990s to 28.8/year in the 2000s, 64.5/year in 2010s, and reached 112/year in 2020-2022, confirming they are hot research topic in the field. These reports were from 93 nations/regions, with the USA, China, Japan, Australia, and England taking the leading positions. Diabetes Research and Clinical Practice was the journal that published the most studies, and Diabetes Care was the most quoted. We identified 6979 authors, with Wong TY having the most papers and being the most commonly co-cited. The most popular keyword, according to our research, is diabetic retinopathy. Oxidative stress, diabetic macular edema (DME), lipid peroxidation, and other topics have often been investigated. DR-related lipid research is conducted mainly in North America, Asia, Oceania, and Europe. Much study has centered on the relationship between lipid-lowering therapy and DR pathogenesis. These studies strongly support using lipid-reducing medications (fenofibrate, statins, and omega-3 PUFAs), combined with hyperglycemia and hypertension therapy, to prevent and treat DR. However, the impact of fenofibrate or statin on retinopathy is not correlated with their action on blood lipid profiles. Thus, more randomized clinical trials with primary endpoints related to DR in T1D or T2D are merited. In addition, the lipid biomarker for DR (lipid aldehydes, ALEs, and cholesterol crystals), the action of lipid-reducing medicines on retinopathy, the mechanism of lipid-lowering medications preventing or curing DR, and ocular delivery of lipid-lowering drugs to diabetic patients are predicted as the research focus in the future in the DR-related lipid research field.",

Affected children suffer progressive neuronal loss, visual failure and premature death. Presently there is no treatment. This study evaluated dual intracerebroventricular (ICV) and intravitreal (IVT) administration of a self-complementary adeno-associated viral vector encoding ovine CLN5 (scAAV9/oCLN5) into CLN5 affected sheep (CLN5-/-) at various disease stages. CLN5 disease progression was slowed in pre-symptomatic sheep who received a moderate dose of scAAV9/oCLN5, whilst a higher ICV dose treatment in early and advanced symptomatic animals delayed or halted disease progression. Intracranial (brain) volume loss was attenuated in all treatment cohorts, and visual function was also sustained in both the early and advanced symptomatic treated sheep over the 24-month duration of the study. Robust CLN5 protein expression was detected throughout the brain and spinal cord, and improvements in central nervous system and retinal disease correlates were observed. These findings hold translational promise for extending and improving the quality of life in both pre-symptomatic and symptomatic CLN5 patients, and prompted the initiation of the first in-human Phase I/II clinical trial testing ICV/IVT administration of scAAV9 encoding human CLN5 (https://clinicaltrials.gov/; NCT05228145).",

Retrospective cohort study analysis of empaneled patients with type 2 diabetes <40\u00a0years old with retinopathy screening within the Los Angeles Department of Health Services between 01/01/2017-07/01/2021 were included. Patients were stratified based on presenting severity of DR determined on fundus photographs or clinical examination. Patient's systemic co-morbidities and ocular outcomes were then compared across each group. Procedural (e.g. intravitreal injections) and surgical interventions (e.g. pars plana vitrectomy) were documented as performed by the treating physician. 2795 patients were screened from 12,456 patients diagnosed with diabetes younger than age 40 (22.4\u00a0%). Of these, 1496 patients were diagnosed with type 2 DM. 1084 (72.4\u00a0%) of patients presented without DR, 307 (20.5\u00a0%) presented with non-proliferative diabetic retinopathy (NPDR), and 105 (7.0\u00a0%) of patients presented with proliferative diabetic retinopathy (PDR). Increasing presenting diabetic retinopathy severity was associated with longer duration of diabetes, greater systemic comorbidities (e.g. diabetic foot disease, neuropathy, chronic kidney or end stage renal disease), worse baseline and final visual acuity, and required more procedural and surgical interventions. Worse presenting DR severity in patients young-onset type 2 diabetes was associated with greater comorbid systemic and ocular disease with worse visual acuity outcomes. <1\u00a0% of patients without diabetic retinopathy or with mild NPDR were likely to progress to PDR. Diabetic kidney disease was an independent risk factor for developing neovascular glaucoma and retinal detachments. Prompt evaluation and intervention in patients with YO-DM2 may help reduce the associated systemic and ocular morbidity.",
        "38227526": "ID: 38227526\nTitle: On implications of somatostatin in diabetic retinopathy.\nAbstract: Somatostatin, a naturally produced neuroprotective peptide, depresses excitatory neurotransmission and exerts anti-proliferative and anti-inflammatory effects on the retina. In this review, we summarize the progress of somatostatin treatment of diabetic retinopathy through analysis of relevant studies published from February 2019 to February 2023 extracted from the PubMed and Google Scholar databases. Insufficient neuroprotection, which occurs as a consequence of declined expression or dysregulation of retinal somatostatin in the very early stages of diabetic retinopathy, triggers retinal neurovascular unit impairment and microvascular damage. Somatostatin replacement is a promising treatment for retinal neurodegeneration in diabetic retinopathy. Numerous pre-clinical and clinical trials of somatostatin analog treatment for early diabetic retinopathy have been initiated. In one such trial (EUROCONDOR), topical administration of somatostatin was found to exert neuroprotective effects in patients with pre-existing retinal neurodysfunction, but had no impact on the onset of diabetic retinopathy. Overall, we concluded that somatostatin restoration may be especially beneficial for the growing population of patients with early-stage retinopathy. In order to achieve early prevention of diabetic retinopathy initiation, and thereby salvage visual function before the appearance of moderate non-proliferative diabetic retinopathy, several issues need to be addressed. These include the needs to: a) update and standardize the retinal screening scheme to incorporate the detection of early neurodegeneration, b) identify patient subgroups who would benefit from somatostatin analog supplementation, c) elucidate the interactions of somatostatin, particularly exogenously-delivered somatostatin analogs, with other retinal peptides in the context of hyperglycemia, and d) design safe, feasible, low cost, and effective administration routes.",

This prospective study included 15 diabetic patients without DR, 16 diabetic patients with non-proliferative DR, 14 patients with pre-proliferative DR, 15 patients with proliferative DR, and 14 age-matched controls. All the participants underwent ophthalmologic examination and full-field ERGs. The ERGs were recorded with the Metrovision MonPackOne system. The latencies were analyzed for \"a\"- and \"b\"-waves in the dark-adapted (DA) 0.01 ERG, DA 3.0 ERG, DA oscillatory potentials, light-adapted (LA) 3.0 ERG, and 30 Hz flicker ERG.

Standardized narrative review of the literature by an international expert workgroup, as part of the DRD Staging System Update Effort, a project of the Mary Tyler Moore Vision Initiative. Overall, there were 6 workgroups: Vascular Retina, Neural Retina, Systemic Health, Basic and Cellular Mechanisms, Visual Function, and Quality of Life. The Vascular Retina workgroup, including 16 participants from 4 countries. Literature review was conducted using standardized evidence grids for 5 modalities: standard color fundus photography (CFP), widefield color photography (WFCP), standard fluorescein angiography (FA), widefield FA (WFFA), and OCT angiography (OCTA). Summary levels of evidence were determined on a validated scale from I (highest) to V (lowest). Five virtual workshops were held for discussion and consensus. Level of evidence for each modality. Levels of evidence for standard CFP, WFCP, standard FA, WFFA, and OCTA were I, II, I, I, and II respectively. Traditional vascular lesions on standard CFP should continue to be included in an updated staging system, but more studies are required before they can be used in posttreatment eyes. Widefield color photographs can be used for severity grading within the area covered by standard CFPs, although these gradings may not be directly interchangeable with each other. Evaluation of the peripheral retina on WFCP can be considered, but the method of grading needs to be clarified and validated. Standard FA and WFFA provide independent prognostic value, but the need for dye administration should be considered. OCT angiography has significant potential for inclusion in the DRD staging system, but various barriers need to be addressed first. This study provides evidence-based recommendations on the utility of various imaging modalities for assessment of the vascular component of DRD, which can inform future updates to the DRD staging system. Although new imaging modalities offer a wealth of information, there are still major gaps and unmet research needs that need to be addressed before this potential can be realized.

The mechanisms underlying the formation of functional neural networks are still only partially understood. Here we analyzed the role of a novel gene si:ch73-364h19.1/drish in the neural and vascular development of zebrafish embryos. We show that drish mRNA is expressed broadly and dynamically in multiple cell types including neural, glial, retinal progenitor and vascular endothelial cells throughout the early stages of embryonic development. To study Drish function during embryogenesis, we generated drish genetic mutant using CRISPR/Cas9 genome editing. drish loss-of-function mutant larvae displayed defects in early retinal ganglion cell, optic nerve and the retinal inner nuclear layer formation, as well as ectopic motor axon branching. In addition, drish mutant adults exhibited deficient retinal outer nuclear layer and showed defective light response and locomotory behavior. However, vascular patterning and blood circulation were not significantly affected. Together, these data demonstrate important roles of zebrafish drish in the retinal ganglion cell, optic nerve and interneuron development and in spinal motor axon branching.",

In recent years, studies have shown that elevated levels of LCN2 have a strong association with diabetic retinopathy (DR), but the pathogenesis is unknown. Here, we reviewed the relevant literature and compiled the pathogenesis associated with LCN2-induced DR. We searched PubMed and Web of Science electronic databases using \"lipocalin-2, diabetic retinopathy, retinal degeneration, diabetic microangiopathies, diabetic neuropathy and inflammation\" as subject terms. In diabetic retinal neuropathy, LCN2 causes impaired retinal photoreceptor function and retinal neurons; in retinal microangiopathy, LCN2 induces apoptosis of retinal vascular endothelial cells and promotes angiogenesis; in retinal inflammation, increased secretion of LCN2 recruits inflammatory cells and induces pro-inflammatory cytokines. Moreover, LCN2 has the potential as a biomarker for DR. Recent studies have shown that retinal damage can be attenuated by silencing LCN2, which may be associated with the inhibition of caspase-1-mediated pyroptosis, and LCN2 may be a new target for the treatment of DR. In conclusion, LCN2, involved in the development of diabetic retinopathy, is a key factor in diabetic retinal microangiopathy, neurodegeneration, and retinal inflammation. LCN2 is likely to be a novel molecular target leading to DR, and a more in-depth study of the pathogenesis of DR caused by LCN2 may provide considerable benefits for clinical research and potential drug development.",

In this case-controlled biobank study, we aimed to ascertain differences in grey and white matter anatomy in people with DM compared with non-diabetic controls (NDC). This study utilises the UK Biobank prospective, population-based, multicentre study of UK residents. Participants with diabetes and age/gender-matched controls without diabetes were selected in a three-to-one ratio. We excluded people with underlying neurological/neurodegenerative disease. Whole brain, cortical, and subcortical volumes (188 regions) were compared between participants with diabetes against NDC corrected for age, sex, and intracranial volume using univariate regression models, with adjustment for multiple comparisons. Diffusion tensor imaging analysis of fractional anisotropy (FA) was performed along the length of 50 white matter tracts. We included 2404 eligible participants who underwent brain magnetic resonance imaging (NDC, n\u00a0=\u00a01803 and DM, n\u00a0=\u00a0601). Participants with DM had a mean (\u00b1standard deviation) diagnostic duration of 18\u00a0\u00b1\u00a011\u00a0years, with adequate glycaemic control (HbA1C 52\u00a0\u00b1\u00a013\u00a0mmol/mol), low prevalence of microvascular complications (diabetic retinopathy prevalence, 5.8%), comparable cognitive function to controls but greater self-reported pain. Univariate volumetric analyses revealed significant reductions in grey matter volume (whole brain, total, and subcortical grey matter), with mean percentage differences ranging from 2.2% to 7% in people with DM relative to NDC (all p\u00a0<\u00a00.0002). The subcortical (bilateral cerebellar cortex, brainstem, thalamus, central corpus callosum, putamen, and pallidum) and cortical regions linked to sensorimotor (bilateral superior frontal, middle frontal, precentral, and postcentral gyri) and visual functions (bilateral middle and superior occipital gyri), all had lower grey matter volumes in people with DM relative to NDC. People with DM had significantly reduced FA along the length of the thalamocortical radiations, thalamostriatal projections, and commissural fibres of the corpus callosum (all; p\u00a0<\u00a00\u00b7001). This analysis suggests that anatomic differences in brain regions are present in a cohort with adequately controlled glycaemia without prevalent microvascular disease when compared with volunteers without diabetes. We hypothesise that these differences may predate overt end-organ damage and complications such as diabetic neuropathy and retinopathy. Central nervous system alterations/neuroplasticity may occur early in the natural history of microvascular complications; therefore, brain imaging should be considered in future mechanistic and interventional studies of DM.",

We investigated indirubin, one of the main bioactive components of the traditional Chinese medicine Danggui Longhui Pill, in the present study for its role in retinal neurodegeneration. Indirubin exhibited no detectable tissue toxicity in vivo or cytotoxicity in vitro. Moreover, indirubin improved visual function and ameliorated retinal neurodegeneration in mice after optic nerve crush injury in vivo. Furthermore, indirubin reduced the apoptosis of retinal ganglion cells induced by oxidative stress in vitro. In addition, indirubin significantly suppressed the increased production of intracellular reactive oxygen species and the decreased activity of superoxide dismutase induced by oxidative stress. Mechanically, indirubin played a neuroprotective role by regulating the PI3K/AKT/BAD/BCL-2 signaling. In conclusion, indirubin protected retinal ganglion cells from oxidative damage and alleviated retinal neurodegeneration induced by optic nerve crush injury.

Given the pivotal role of dysfunctional mitochondria and oxidative stress in early DR, our objective was to observe mitochondria-related alterations in the neural retina of type one diabetic mellitus mice with no evidence of DR (T1DM-NDR). We aimed to identify the key mitochondrial-related proteins contributing to mitochondrial injury. Our study revealed that T1DM-NDR mice exhibited outer retina thinning, including the ellipsoid zone, inner segment, and outer segment. Additionally, there was an impaired amplitude of the b-wave in electroretinogram (ERG) and a disorganized arrangement of the photoreceptor layer. In both the retina of DM mice and high glucose (HG)-treated 661w cells, mitochondria appeared swollen and fragmented, with disrupted cristae, disorganized or shortened branches in the mitochondrial network, and decreased mitochondrial membrane potential. Among the mitochondrial-related proteins, dynamin-related protein 1 (Drp1) was upregulated, and the ratio of phosphorylated Drp1 protein at serine 616 (S616) and serine 637 (S637) sites significantly increased in the retina of DM mice. The administration of Mdivi-1 ameliorated high-glucose-induced dysfunctional mitochondria, thereby protecting T1DM-NDR mice retina from morphological and functional injuries. Our findings suggest that hyperglycemia promotes Drp1-mediated mitochondrial dysfunction, which may be a significant factor in the development of DR. The inhibition of high-glucose-induced mitochondrial fission emerges as a potential and innovative intervention strategy for preventing DR.",

A peculiarity of the neurodegenerative processes is the variable susceptibility among distinct neuronal populations, exemplified by the contrasting resilience of motor neurons innervating the ocular motor system and the more vulnerable facial and hypoglossal motor neurons. The crucial role of vascular endothelial growth factor (VEGF) as a neuroprotective factor in the nervous system is well-established since a deficit of VEGF has been related to motoneuronal degeneration. In this study, we investigated the survival of ocular, facial, and hypoglossal motor neurons utilizing the murine SOD1G93A ALS model at various stages of the disease. Our primary objective was to determine whether the survival of the different brainstem motor neurons was linked to disparate VEGF expression levels in resilient and susceptible motor neurons throughout neurodegeneration. Our findings revealed a selective loss of motor neurons exclusively within the vulnerable nuclei. Furthermore, a significantly higher level of VEGF was detected in the more resistant motor neurons, the extraocular ones. We also examined whether TDP-43 dynamics in the brainstem motor neuron of SOD mice was altered. Our data suggests that the increased VEGF levels observed in extraocular motor neurons may potentially underlie their resistance during the neurodegenerative processes in ALS in a TDP-43-independent manner. Our work might help to better understand the underlying mechanisms of selective vulnerability of motor neurons in ALS.",

Macrophages are found in all ocular tissues, spanning from the front surface, including the cornea, to the posterior pole, represented by the choroid/sclera. The neural retina is also populated by specialised resident macrophages called microglia. The plasticity of microglia/macrophages allows them to adopt different activation states in response to changes in the tissue microenvironment. When exposed to various factors, microglia/macrophages polarise into distinct phenotypes, each exhibiting unique characteristics and roles. Furthermore, extensive research has indicated a close association between microglia/macrophage polarisation and the development and reversal of various intraocular diseases. The present article provides a review of the recent findings on the association between microglia/macrophage polarisation and ocular pathological processes (including autoimmune uveitis, optic neuritis, sympathetic ophthalmia, retinitis pigmentosa, glaucoma, proliferative vitreoretinopathy, subretinal fibrosis, uveal melanoma, ischaemic optic neuropathy, retinopathy of prematurity and choroidal neovascularization). The paradoxical role of microglia/macrophage polarisation in retinopathy of prematurity is also discussed. Several studies have shown that microglia/macrophages are involved in the pathology of ocular diseases. However, it is required to further explore the relevant mechanisms and regulatory processes. The relationship between the functional diversity displayed by microglia/macrophage polarisation and intraocular diseases may provide a new direction for the treatment of intraocular diseases.",

Post-transcriptional gene regulation can control RNA's fate, and defects in RNA processing are critical determinants of MN degeneration. N6-methyladenosine (m6A) is a post-transcriptional RNA modification that controls diverse aspects of RNA metabolism. To assess the m6A requirement in MNs, we depleted the m6A methyltransferase-like 3 (METTL3) in cells and mice. METTL3 depletion in embryonic stem cell-derived MNs has profound and selective effects on survival and neurite outgrowth. Mice with cholinergic neuron-specific METTL3 depletion display a progressive decline in motor behavior, accompanied by MN loss and muscle denervation, culminating in paralysis and death. Reader proteins convey m6A effects, and their silencing phenocopies METTL3 depletion. Among the m6A targets, we identified transactive response DNA-binding protein 43 (TDP-43) and discovered that its expression is under epitranscriptomic control. Thus, impaired m6A signaling disrupts MN homeostasis and triggers neurodegeneration conceivably through TDP-43 deregulation.",

This was a retrospective study of patients from the University of Colorado Cataract Outcomes Registry. The primary outcomes were refraction prediction error (RPE), mean absolute RPE, and median absolute RPE. Outcomes were stratified by five axial length groups. Univariate and multivariate models for RPE were stratified by the AL group. Two hundred eighty-one eyes with prior LASIK/PRK and 3101 eyes without are included in the study. Patients with prior LASIK/PRK were significantly younger: 67.0 vs 69.9\u00a0years, p\u2009<\u20090.0001. The LASIK/PRK group had significantly better mean pre-operative BCVA in comparison to the non-LASIK group, logMAR 0.204 vs logMAR 0.288, p\u2009=\u20090.003. The LASIK/PRK group had significantly lower rates of cardiovascular disease (18.5% vs 29.3%, p\u2009<\u20090.001), hypertension (49.1% vs 59.3%, p\u2009<\u20090.012), and type 2 diabetes (10.7% vs 26.0%, p\u2009<\u20090.001), and no significant difference in psychiatric disease. The absolute RPE was higher for the LASIK group for all ALs, but only significantly higher for eyes with AL less than 25\u00a0mm. Patient eyes with prior LASIK/PRK surgery undergoing cataract surgery were significantly younger, had significantly less comorbidities, and a significantly better pre-operative BCVA. Using the Barrett formulas, absolute prediction error for eyes with longer ALs was not significantly worse for LASIK/PRK eyes than those without and the difference was smaller for eyes with longer AL.",

These conditions include age-related macular degeneration or diabetic retinopathy. Regulatory T cells play a vital role in immunoregulation of the nervous system by limiting inflammation and tissue damage in health and disease. Because the retina was long-considered an immunoprivileged site, the precise contribution of regulatory T cells in retinal homeostasis and in age-related retinal diseases remains unknown. Regulatory T cells were selectively depleted in both young (2-4 months) and aged (18-23 months) FoxP3-DTR mice. We evaluated neuroretinal degeneration, gliosis, subretinal space phagocyte infiltration, and retinal pigmented epithelium morphology through immunofluorescence analysis. Subsequently, aged Treg depleted animals underwent adoptive transfer of both young and aged regulatory T cells from wild-type mice, and the resulting impact on neurodegeneration was assessed. Statistical analyses employed included the U-Mann Whitney test, and for comparisons involving more than two groups, 1-way ANOVA analysis followed by Bonferroni's post hoc test. Our study shows that regulatory T cell elimination leads to retinal pigment epithelium cell dysmorphology and accumulation of phagocytes in the subretinal space of young and aged mice. However, only aged mice experience retinal neurodegeneration and gliosis. Surprisingly, adoptive transfer of young but not aged regulatory T cells reverse these changes. Our findings demonstrate an essential role for regulatory T cells in maintaining age retinal homeostasis and preventing age-related neurodegeneration. This previously undescribed role of regulatory T cells in limiting retinal inflammation, RPE/choroid epithelium damage and subsequently photoreceptor loss with age, opens novel avenues to explore regulatory T cell neuroprotective and anti-inflammatory properties as potential therapeutic approaches for age-related retinal diseases.",

This disease-causing expansion leads to a reduction in C9ORF72 expression levels in patients, suggesting loss of C9ORF72 function could contribute to disease. To further understand the consequences of C9ORF72 deficiency in vivo, we generated a c9orf72 mutant zebrafish line. Analysis of the adult female spinal cords revealed no appreciable neurodegenerative pathology such as loss of motor neurons or increased levels of neuroinflammation. However, detailed examination of adult female c9orf72-/- retinas showed prominent neurodegenerative features, including a decrease in retinal thickness, gliosis, and an overall reduction in neurons of all subtypes. Analysis of rod and cone cells within the photoreceptor layer showed a disturbance in their outer segment structure and rhodopsin mislocalization from rod outer segments to their cell bodies and synaptic terminals. Thus, C9ORF72 may play a previously unappreciated role in retinal homeostasis and suggests C9ORF72 deficiency can induce tissue specific neuronal loss.",

However, due to various endogenous and exogenous factors, the body may produce excessive ROS, which leads to oxidative stress (OS). Numerous studies have shown that OS causes a variety of pathological changes in cells, including mitochondrial dysfunction, DNA damage, telomere shortening, lipid peroxidation, and protein oxidative modification, all of which can trigger apoptosis and senescence. OS also induces a variety of aging-related diseases, such as retinal disease, neurodegenerative disease, osteoarthritis, cardiovascular diseases, cancer, ovarian disease, and prostate disease. In this review, we aim to introduce the multiple internal and external triggers that mediate ROS levels in rodents and humans as well as the relationship between OS, aging, and aging-related diseases. Finally, we present a statistical analysis of effective antioxidant measures currently being developed and applied in the field of aging research.",

The chapter provides an overview of lacrimal fluid composition, elucidating the roles of proteins, lipids, metabolites, and nucleic acids within the tear film. Pooled versus single-tear analysis is discussed to underline the benefits and challenges associated with both approaches, offering insights into optimal strategies for tear sample analysis. Subsequently, an in-depth analysis of tear collection methods is presented, with a focus on Schirmer's test strips and microcapillary tubes methods. Alternative tear collection techniques are also explored, shedding light on their applicability and advantages. Variability factors, including age, sex, and diurnal fluctuations, are examined in the context of their impact on tear biomarker analysis. The main body of the chapter is dedicated to discussing specific biomarkers associated with ocular discomfort and a wide array of ocular diseases. From dry eye disease and thyroid-associated ophthalmopathy to keratoconus, age-related macular degeneration, diabetic retinopathy, and glaucoma, the intricate relationship between molecular biomarkers and these conditions is thoroughly dissected. Expanding beyond ocular pathologies, the chapter explores the applicability of tear biomarkers in diagnosing systemic diseases such as multiple sclerosis, amyotrophic lateral sclerosis, Alzheimer's disease, Parkinson's disease, and cancer. This broader perspective underscores the potential of lacrimal fluid analysis in offering non-invasive diagnostic tools for conditions with far-reaching implications.",

However, direct interactions between these features have not been investigated so far. Therefore, we aimed to analyze associations between the retinal functional hyperemic response to light stimulation and the thickness of individual neuroretinal layers in eyes with early non-proliferative DR. Thirty patients with type 1 diabetes featuring mild (n\u2009=\u200915) or moderate (n\u2009=\u200915) non-proliferative DR and 14 healthy subjects were included in this cross-sectional study. Retinal vessel diameters were measured before and during illumination with flickering light using a dynamic vessel analyzer. Individual layer thickness in the macula was analyzed from spectral domain optical coherence tomography. Flicker light-induced vessel dilation was significantly reduced in patients compared to healthy controls (veins: 3.0% vs. 6.1%, p\u2009<\u20090.001; arteries: 1.3% vs. 5.1%, p\u2009=\u20090.005). Univariately, the response in retinal veins of diabetes patients correlated significantly with ganglion cell layer (GCL) thickness (r\u2009=\u20090.46, p\u2009=\u20090.010), and negatively with hemoglobin A1c (HbA1c) levels (r=-0.41, p\u2009=\u20090.023) and age (r=-0.38, p\u2009=\u20090.037), but not with baseline diameters, glucose levels, or diabetes duration. In a multiple regression model only GCL thickness (p\u2009=\u20090.017, \u03b2\u2009=\u20090.42) and HbA1c (p\u2009=\u20090.045, \u03b2=-0.35) remained significantly associated with the vascular flicker light response. The results indicate that thinner GCL and worse glycemic control both contribute to reduced retinal neurovascular coupling in patients with clinical signs of DR. Progression of neurovascular dysfunction in DR might be related to structural degeneration of the neurovascular complex in the inner retina.",

We included 265 newly diagnosed ALS patients during 2016-2022 in Stockholm and 207 ALS-free siblings and partners of the patients as controls. Information on body mass index (BMI), smoking, and history of head injuries, diabetes mellitus, hypercholesterolemia, and hypertension was obtained through the Euro-MOTOR questionnaire at recruitment. Patients were followed from diagnosis until death, invasive ventilation, or November 30, 2022. Higher BMI at recruitment was associated with lower risk for ALS (OR 0.89, 95%CI 0.83-0.95), especially among those diagnosed after 65\u00a0years. One unit increase in the average BMI during the 3 decades before diagnosis was associated with a lower risk for ALS (OR 0.94, 95%CI 0.89-0.99). Diabetes was associated with lower risk of ALS (OR 0.38, 95%CI 0.16-0.90), while hypercholesterolemia was associated with higher risk of ALS (OR 2.10, 95%CI 1.13-3.90). Higher BMI at diagnosis was associated with lower risk of death (HR 0.91, 95%CI 0.84-0.98), while the highest level of smoking exposure (in pack-years) (HR 1.90, 95%CI 1.20-3.00), hypercholesterolemia (HR 1.84, 95%CI 1.06-3.19), and hypertension (HR 1.76, 95%CI 1.03-3.01) were associated with higher risk of death, following ALS diagnosis. Higher BMI and diabetes were associated with lower risk of ALS. Higher BMI was associated with lower risk of death, whereas smoking (especially in high pack-years), hypercholesterolemia, and hypertension were associated with higher risk of death after ALS diagnosis.",

While there are five FDA-approved drugs for treating this disease, each has only modest benefits. To design new and more effective therapies for ALS, particularly for sporadic ALS of unknown and diverse etiologies, we must identify key, convergent mechanisms of disease pathogenesis. This review focuses on the origin and effects of glutamate-mediated excitotoxicity in ALS (the cortical hyperexcitability hypothesis), in which increased glutamatergic signaling causes motor neurons to become hyperexcitable and eventually die. We characterize both primary and secondary contributions to excitotoxicity, referring to processes taking place at the synapse and within the cell, respectively. 'Primary pathways' include upregulation of calcium-permeable AMPA receptors, dysfunction of the EAAT2 astrocytic glutamate transporter, increased release of glutamate from the presynaptic terminal, and reduced inhibition by cortical interneurons-all of which have been observed in ALS patients and model systems. 'Secondary pathways' include changes to mitochondrial morphology and function, increased production of reactive oxygen species, and endoplasmic reticulum (ER) stress. By identifying key targets in the excitotoxicity cascade, we emphasize the importance of this pathway in the pathogenesis of ALS and suggest that intervening in this pathway could be effective for developing therapies for this disease.",

The present study aimed to identify the pathophysiological functions and affected genes in patients with MNDs, specifically Amyotrophic Lateral Sclerosis (ALS) and Primary Lateral Sclerosis (PLS). The GSE56808 dataset comprised three sample groups: six patients diagnosed with ALS (GSM1369650, GSM1369652, GSM1369654, GSM1369656, GSM1369657, GSM1369658), five patients diagnosed with PLS (GSM1369648, GSM1369649, GSM1369653, GSM1369655, GSM1369659), and six normal controls (GSM1369642, GSM1369643, GSM1369644, GSM1369645, GSM1369646, and GSM1369647). The application of computational analysis of microarray gene expression profiles enabled us to identify 346 significantly differentially expressed genes (DEGs), 169 genes for the ALS sample study, and 177 genes for the PLS sample study. Enrichment was carried out using MCODE, a Cytoscape plugin. Functional annotation of DEGs was carried out via ClueGO/CluePedia (v2.5.9) and further validated via the DAVID database. NRP2, SEMA3D, ROBO3 and, CACNB1, CACNG2 genes were identified as the gene of interest for ALS and PLS sample groups, respectively. Axonal guidance (GO:0007411) and calcium ion transmembrane transport (GO:0070588) were identified to be some of the significantly dysregulated gene ontology (GO) terms, with arrhythmogenic right ventricular cardiomyopathy (KEGG:05412) to be the top relevant KEGG pathway which is affected in MND patients. ROBO3 gene was observed to have distinctive roles in ALS and PLS-affected patients, hinting towards the differential progression of ALS from PLS. The insights derived from our comprehensive analysis accentuate the distinct variances in the underlying molecular pathogenesis of ALS and PLS. Further research should investigate the mechanistic roles of the identified DEGs and molecular pathways, leading to potential targeted therapies for ALS and PLS.",

However, vascular changes and potential effects on neural cells before clinical diagnosis of DR are less well understood. To study the earliest stages of DR, we performed histological phenotyping and quantitative analysis on postmortem retinas from 10 donors with diabetes and without signs of DR (e.g., microaneurysms, hemorrhages), plus three control eyes and one donor eye with DR. We focused on capillary loss in the deeper vascular plexus (DVP) and superficial vascular plexus (SVP), and on neural retina effects. The eye with advanced DR had profound vascular and neural damage, whereas those of the 10 randomly selected donors with diabetes appeared superficially normal. The SVP was indistinguishable from those of the control eyes. In contrast, more than half of the retinas from donors with diabetes had capillary dropout in the DVP and increased capillary diameter. However, we could not detect any localized neural cell loss in the vicinity of dropout capillaries. Instead, we observed a subtle pan-retinal loss of inner nuclear layer cells in all diabetes cases (P < 0.05), independent of microvascular damage. In conclusion, our findings demonstrate a novel histological biomarker for early-stage diabetes-related damage in the human postmortem retina; the biomarker is common in people with diabetes before clinical DR diagnosis. Furthermore, the mismatch between capillary dropout and neural loss leads us to question the notion of microvascular loss directly causing neurodegeneration at the earliest stages of DR, so diabetes may affect the two readouts independently.",

However, achieving survival poses a significant challenge when culturing induced MNs, especially when aiming to reach late maturation stages. Utilizing hiPSC-derived motor neurons and primary mouse astrocytes, we assembled two types of coculture systems: direct coculturing of neurons with astrocytes and indirect coculture using culture inserts that physically separate neurons and astrocytes. Both systems significantly enhance neuron survival. Compared with these two systems, no significant differences in neurodevelopment, maturation, and survival within 3\u2005weeks, allowing to prepare neurons at maturation stages. Using the indirect coculture system, we obtained highly pure MNs at the late mature stage from hiPSCs. Transcriptomic studies of hiPSC-derived MNs showed a typical neurodevelopmental switch in gene expression from the early immature stage to late maturation stages. Mature genes associated with neurodevelopment and synaptogenesis are highly enriched in MNs at late stages, demonstrating that these neurons achieve maturation. This study introduces a novel tool for the preparation of highly pure hiPSC-derived neurons, enabling the determination of neurological disease pathogenesis in neurons at late disease onset stages through biochemical approaches, which typically necessitate highly pure neurons. This advancement is particularly significant in modeling age-related neurodegeneration.",

This decline is promoted by structural and functional mitochondrial deficits, including electron transport chain (ETC) impairments, increased oxidative stress, and reduced energy (ATP) production. These cellular mechanisms associated with progressive optic nerve atrophy have been similarly observed in familial dysautonomia (FD) patients, who experience gradual loss of visual acuity due to the degeneration of RGCs, which is thought to be caused by a breakdown of mitochondrial structures, and a disruption in ETC function. Retinal metabolism plays a crucial role in meeting the elevated energetic demands of this tissue, and recent characterizations of FD patients' serum and stool metabolomes have indicated alterations in central metabolic processes and potential systemic deficits of taurine, a small molecule essential for retina and overall eye health. The present study sought to elucidate metabolic alterations that contribute to the progressive degeneration of RGCs observed in FD. Additionally, a critical subpopulation of retinal interneurons, the dopaminergic amacrine cells, mediate the integration and modulation of visual information in a time-dependent manner to RGCs. As these cells have been associated with RGC loss in the neurodegenerative disease Parkinson's, which shares hallmarks with FD, a targeted analysis of the dopaminergic amacrine cells and their product, dopamine, was also undertaken. One dimensional (1D) proton (1H) nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry, and retinal histology methods were employed to characterize retinae from the retina-specific Elp1 conditional knockout (CKO) FD mouse model (Pax6-Cre; Elp1LoxP/LoxP). Metabolite alterations correlated temporally with progressive RGC degeneration and were associated with reduced mitochondrial function, alterations in ATP production through the Cahill and mini-Krebs cycles, and phospholipid metabolism. Dopaminergic amacrine cell populations were reduced at timepoints P30-P90, and dopamine levels were 25-35% lower in CKO retinae compared to control retinae at P60. Overall, this study has expanded upon our current understanding of retina pathology in FD. This knowledge may apply to other retinal diseases that share hallmark features with FD and may help guide new avenues for novel non-invasive therapeutics to mitigate the progressive optic neuropathy in FD.",

In ophthalmology, pathogenic variants in CFAP410 have been described in association with cone rod dystrophy, retinitis pigmentosa, with or without macular staphyloma, or with systemic abnormalities such as skeletal dysplasia and amyotrophic lateral sclerosis. Herein, we report a consanguineous family with a novel homozygous CFAP410 c.335_346del variant with cone only degeneration and no systemic features. A retrospective analysis of ophthalmic history, examination, retinal imaging, electrophysiology and microperimetry was performed as well as genetic testing with in silico pathogenicity predictions and a literature review. A systemically well 28-year-old female of Pakistani ethnicity with parental consanguinity and no relevant family history, presented with childhood-onset poor central vision and photophobia. Best-corrected visual acuity and colour vision were reduced (0.5 LogMAR, 6/17 Ishihara plates (right) and 0.6 LogMAR, 3/17 Ishihara plates (left). Fundus examination showed no pigmentary retinopathy, no macular staphyloma and autofluorescence was unremarkable. Optical coherence tomography showed subtle signs of intermittent disruption of the ellipsoid zone. Microperimetry demonstrated a reduction in central retinal sensitivity. Electrodiagnostic testing confirmed a reduction in cone-driven responses. Whole-genome sequencing identified an in-frame homozygous deletion of 12 base pairs at c.335_346del in CFAP410.

        "39236857": "ID: 39236857\nTitle: Dysfunctional mitochondria in age-related neurodegeneration: Utility of melatonin as an antioxidant treatment.\nAbstract: Mitochondria functionally degrade as neurons age. Degenerative changes cause inefficient oxidative phosphorylation (OXPHOS) and elevated electron leakage from the electron transport chain (ETC) promoting increased intramitochondrial generation of damaging reactive oxygen and reactive nitrogen species (ROS and RNS). The associated progressive accumulation of molecular damage causes an increasingly rapid decline in mitochondrial physiology contributing to aging. Melatonin, a multifunctional free radical scavenger and indirect antioxidant, is synthesized in the mitochondrial matrix of neurons. Melatonin reduces electron leakage from the ETC and elevates ATP production; it also detoxifies ROS/RNS and via the SIRT3/FOXO pathway it upregulates activities of superoxide dismutase 2 and glutathione peroxidase. Melatonin also influences glucose processing by neurons. In neurogenerative diseases, neurons often adopt Warburg-type metabolism which excludes pyruvate from the mitochondria causing reduced intramitochondrial acetyl coenzyme A production. Acetyl coenzyme A supports the citric acid cycle and OXPHOS. Additionally, acetyl coenzyme A is a required co-substrate for arylalkylamine-N-acetyl transferase, which rate limits melatonin synthesis; therefore, melatonin production is diminished in cells that experience Warburg-type metabolism making mitochondria more vulnerable to oxidative stress. Moreover, endogenously produced melatonin diminishes during aging, further increasing oxidative damage to mitochondrial components. More normal mitochondrial physiology is preserved in aging neurons with melatonin supplementation.",

Ocular symptoms are generally not considered classic ALS symptoms, although RGCs and spinal motor neurons share certain cell pathologies, including hallmark signs of glutamate neurotoxicity, which may be triggered by activation of extrasynaptic NMDA receptors (NMDARs). To explore potential novel strategies to prevent ALS-associated death of RGCs, we utilized inhibition of the TwinF interface, a new pharmacological principle that detoxifies extrasynaptic\u00a0NMDARs by disrupting the NMDAR/TRPM4 death signaling complex. Using the ALS mouse model SOD1G93A, we found that the small molecule TwinF interface inhibitor FP802 prevents the loss of RGCs, improves pattern electroretinogram (pERG) performance, increases the retinal expression of Bdnf,\u00a0and restores the retinal\u00a0expression of the immediate early genes, Inhibin beta A and Npas4. Thus, FP802 not only prevents, as recently described, death of spinal motor neurons in SOD1G93A mice, but it\u00a0also mitigates ALS-associated retinal damage. TwinF interface inhibitors have great potential for alleviating neuro-ophthalmologic symptoms in ALS patients and offer a promising new avenue for therapeutic intervention.",

These syndromes are very rare and often present diagnostic and therapeutic challenges. Motor neuron disease as a paraneoplastic condition is particularly uncommon, especially in association with gastrointestinal malignancies like sigmoid colon adenocarcinoma. A 62-year-old male with type 2 diabetes mellitus (T2DM) presented with chronic diarrhea and a three-year history of progressive bilateral limb weakness. Initial symptoms were attributed to diabetic neuropathy, but the rapid progression and severity warranted further investigation. Neurological examination revealed hypotonia, muscle wasting, and absent reflexes in all four limbs. Diagnostic tests, including electromyography (EMG) and nerve conduction studies, confirmed motor sensory axonal neuropathy. A colonoscopy revealed a mass in the sigmoid colon, and a biopsy confirmed adenocarcinoma. The patient was managed with surgical resection of the tumor, adjuvant chemotherapy, and immunomodulatory treatments, resulting in the stabilization of neurological symptoms.

A multicenter cohort of 736 patients.\nAbstract: Vision-threatening diabetic retinopathy (VTDR) included severe non-proliferative diabetic retinopathy (NPDR), proliferative diabetic retinopathy (PDR) and clinically significant diabetic macular edema (DME). To compare the axial length (AL) and assess its influence on VTDR across different ages. A retrospective cohort study. Medical chart review was performed in 736 consecutive patients with VTDR. The patients were divided into young (\u2264\u200945\u00a0years) and elderly group (>\u200945\u00a0years) based on their age at the diagnosis of VTDR. After at least one year of standardized treatments, all eligible patients were followed up. The main outcome measures included the presence of tractional retinal detachment (TRD) involving foveal, final best-corrected visual acuity (BCVA), the development of neovascular glaucoma (NVG), and recurrent vitreous hemorrhage (VH) post-vitrectomy. ALs were compared between two age groups. The impact of AL on clinical outcomes was determined by logistic analyses after controlling for systemic parameters. The study included 144 patients\u2009\u2264\u200945\u00a0years and 592 patients\u2009>\u200945\u00a0years. Young patients had significantly longer AL than elderly participants (23.9\u00a0mm vs 23.0\u00a0mm, p\u2009<\u20090.001). Over a median follow-up of 25.9\u00a0months, a larger proportion of young patients developed TRD (34.7% vs 16.2%, p\u2009<\u20090.001) and recurrent VH (18.6% vs 10.3%, p\u2009=\u20090.040) than elderly patients. In elderly group, longer AL is an independent protective factor in preventing TRD (odds ratio [OR], 0.5; 95% confidence interval [CI], 0.4-0.7; P\u2009<\u20090.001). However, this beneficial effect was not observed in young patients. Young patients with VTDR exhibited significantly longer AL but more aggressive clinical signs with compromised prognosis. In elderly group, a longer AL independently reduced the risk of TRD, while this protective effect did not exist for young patients.",

A cross-sectional case-control study. Ninety-seven eyes with NPDR, 49 with no central MAs and 48 with central MAs, underwent color fundus photography and optical coherence tomography (OCT)/OCT-angiography (OCT-A). Thickness of central macula, retinal nerve fiber layer (NFL), ganglion cell layer (GCL+) and NFL\u2009+\u2009GCL\u2009+\u2009was evaluated on OCT. FAZ metrics (ImageJ), perfusion and vessel density (PD/VD), and fractal dimension (FD) (MATLAB) were evaluated on 3\u2009\u00d7\u20093 OCT-A slabs of both superficial and deep capillary plexuses (SCP/DCP). All evaluations were performed on the full image and after subdivision in 4 quadrants. In the MA group, 77 MAs were detected (45.5% in the DCP). The MA group showed: increased FAZ area and perimeter in the SCP (p\u2009<\u20090.01) and DCP (p\u2009=\u20090.02), and reduced circularity index in the SCP (p\u2009=\u20090.03); reduced VD in the SCP (p\u2009<\u20090.01) and reduced PD, VD (p\u2009<\u20090.01) and FD (p\u2009=\u20090.02) in the DCP; decreased VD and FD in the SCP (p\u2009=\u20090.02 and p\u2009=\u20090.05), and in VD and FD in the DCP in the inferior quadrant (p\u2009=\u20090.04 and p\u2009=\u20090.03); a decrease in VD in the SCP in the nasal quadrant (p\u2009=\u20090.05).

Excess of aldosterone, the specific MR ligand, is known to stimulate the production of proinflammatory cytokines and chemokines in extrarenal tissues and cells. In the RPE/choroid complex, aldosterone upregulated genes encoding proteins of the inflammatory response and downregulated genes encoding proteins involved in synaptic activity and neurotransmitters. Yet, cortisol, which is the main MR ligand in the eye, is a potent anti-inflammatory endogenous glucocorticoid. The aim of the present work was to better understand the role of MR activation in retinal inflammation either by acute injection of aldosterone or overexpression of the receptor. We first analyzed the retinal transcriptomic regulation induced by acute intraocular injection of aldosterone in the rat. Then, we used a transgenic rat overexpressing human MR (hMR) to also conduct retinal transcriptomic analysis as well as histological evaluation of the retina, retinal pigment epithelium and choroid. Our results show that acute intravitreal injection of aldosterone is highly proinflammatory, upregulating pathways related to microglial activation, oxidative stress, cell death, and downregulating pathways related to glial/neuronal cells activity and proper neurotransmission. On the other hand, hMR overexpression mediates a low-grade inflammation in the retina, associated with notable choroidal inflammation and choroidal neuropathy. Consequences of hMR overexpression or aldosterone-injection on retinal transcriptome reveal very distinct pathological mechanisms, with only a few common genes regulated, most of them not being regulated in the same way. Although aldosterone is highly proinflammatory in the retina, MR overactivation in its physiologic milieu mediates a low-grade inflammation in the neural retina.",

Recently the MPS has focused on mortality patterns from neurological and behavioral conditions, e.g., Parkinson's disease, Alzheimer's disease, dementia, and motor neuron disease such as amyotrophic lateral sclerosis. A fuller picture of radiation-related late effects comes from studying both mortality and the occurrence (incidence) of conditions not leading to death. Accordingly, the MPS is identifying neurocognitive diagnoses from fee-for-service insurance claims from the Centers for Medicare and Medicaid Services (CMS), among Medicare beneficiaries beginning in 1999 (the earliest date claims data are available). Linkages to date have identified \u223c540,000 workers with available health information. Such linkages provide individual information on important co-factor and confounding variables such as smoking, alcohol consumption, blood pressure, obesity, diabetes and many other health and demographic characteristics. The total person-level set of time-dependent variables, outcomes, organ-specific dose measures, co-factors, and demographics will be massive and much too large to be evaluated with standard software. Thus, development of specialized open-source software designed for large datasets (Colossus) is nearly complete. The wealth of information available from CMS claims data, coupled with individual dose reconstructions, will thus greatly enhance the quality and precision of health evaluations for this new field of low-dose radiation and neurocognitive effects.",

To address this gap, University Hospitals, Reference Services for Neonatal Screening, and Reference Services for Rare Diseases, all of which are public health institutions, established the Brazilian Rare Diseases Network (RARAS) in 2020. The objective of this study was to perform a comprehensive nationwide epidemiological investigation of individuals with RDs in Brazil. This retrospective survey collected data from patients receiving care in 34 healthcare facilities affiliated with RARAS in 2018 and 2019. The survey included 12,530 participants with a median age of 15.0\u00a0years, with women representing 50.5% of the cohort. Classification according to skin color\u00a0demonstrated that 5044 (47.4%) participants\u00a0were admixed. Most had a confirmed diagnosis (63.2%), with a predominance of phenylketonuria (PKU), cystic fibrosis (CF), and acromegaly. Common clinical manifestations included global developmental delay and seizures. The average duration of the diagnostic odyssey was 5.4\u00a0years (\u00b1\u20097.9\u00a0years). Among\u00a0the confirmed diagnoses, 52.2% were etiological (biochemical: 42.5%; molecular: 30.9%), while 47.8% were clinical. Prenatal diagnoses accounted for 1.2%. Familial recurrence and consanguinity rates were 21.6% and 6.4%, respectively. Mainstay treatments included drug therapy (55.0%) and rehabilitation (15.6%). The Public Health System funded most diagnoses (84.2%) and treatments (86.7%). Hospitalizations were reported in 44.5% of cases, and the mortality rate was 1.5%, primarily\u00a0due to motor neuron disease and CF. This study marks a pioneering national-level data collection effort for rare diseases in Brazil, offering novel insights to advance the understanding, management, and resource allocation for RDs.

This effect has been observed primarily in French, but also in English and Hungarian. However, a recent implementation by Kim, McLaren & Lee (2024), aiming to replicate the RPE in English (Chern, Tillmann, Vaughan & Gordon, 2018), was not successful, inviting a discussion about the conditions under which the RPE could be observed. We here discuss features of Kim et al.'s (2024) implementation that might have reduced the probability of observing the RPE. Compared to Chern et al. (2018), and numerous other studies reporting the RPE, additional delays after the primes and before each sentence were introduced by Kim et al. (2024). This change might have limited beneficial prime effects, which persist, but decay over time. Further, their instruction to \"relax and have some rest\" might have reduced attentive processing of the primes and related entrainment. Finally, their sample was small (n =16 per experiment) and with a large age range for investigating typically developing children (7-12y), potentially reducing experimental effects due to development-related individual variations. These methodological changes and sample characteristics are discussed in relation to previous research on the RPE, and entrainment in general. This discussion prompts the need for future research to investigate conditions leading to the RPE, with the aim to shed light on underlying mechanisms. Better understanding the RPE will be critical for the use of rhythmic priming within clinical and educational settings.",

Common neurodegenerative disorders are Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), spinocerebellar ataxia (SCA), and supranuclear palsy. There is a lack of effective treatment for neurodegenerative diseases, and scientists are putting their efforts into developing therapies against them. Stem cell therapy has emerged as a hope for neurodegenerative disorders since it is not only the damaged neurons that might be replaced, but other neuromodulators and neuroprotectors are secreted. Stem cell terminal differentiation before implantation ensures the implantation of correct cells and molecular markers like carbonic anhydrase II, CNPase (2',3'-cyclic nucleotide 3'-phosphohydrolase), myelin basic protein (MBP), and myelin oligodendrocyte glycoprotein (MOG) elucidate the differentiation. Secretion of various growth factors like epidermal growth factor (EGF), keratinocyte growth factor (KGF), vascular endothelial growth factor-\u03b1 (VEGF-\u03b1), transforming growth factor (TGF), and macrophage inflammatory protein (MIP) supports cell survival, cell proliferation, blood vessel formation, axon regeneration, and neuroglial functional connection formation at the site of degeneration. Adverse effects of stem cell therapy, like teratogenicity and differentiation in different cells other than the desired one under the influence of microenvironment, are a few key concerns. Post-transplantation improved synaptic plasticity, apoptosis inhibition, and reduction in tau-phosphorylation and amyloid beta (A\u03b2) production has been observed in Alzheimer's patients. A large number of experimental, preclinical, and clinical studies have been conducted, and encouraging results have been obtained.

Early diagnosis of the diseases is difficult due to the lack of disease-specific tests. Adding new biomarkers external to the CNS facilitates the diagnosis of neurological diseases. In this respect, the retina has a common embryologic origin with the CNS. Retinal imaging technologies including optical coherence tomography (OCT) can be used in the understanding and processual monitoring of neurological diseases. Retinal imaging has been recently recognized as a potential source of biomarkers for neurological diseases, increasing the number of studies in this direction. In this review, the association of retinal abnormalities with Parkinson's disease (PD), multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), and Alzheimer's disease (AD) is explained. Structural and functional abnormalities in retina as a predictive marker may facilitate early diagnosis of diseases. Although not all retinal abnormalities are predictive of neurologic diseases, changes in the retinal layers including retinal pigment epithelium and plexiform layers should suggest the risk of PD, MS, ALS, and AD.",

We aimed to determine whether there is an association of CMDs, namely, any cardiovascular disease, cardiac arrhythmia, heart failure, thromboembolic disease, hypertension, cerebrovascular disease, ischemic heart disease, diabetes mellitus type 2, and hypercholesterolemia with the risk and progression of MNDs. We included 1463 MND patients (amyotrophic lateral sclerosis (ALS), primary lateral sclerosis (PLS), progressive spinal muscular atrophy (PSMA), and unspecified MND) diagnosed from January 1, 2015, to July 1, 2023, in Sweden according to the Swedish Motor Neuron Disease Quality Registry (i.e., cases), up to 5 MND-free population controls per case (N\u00a0=\u00a07311) who were individually matched to the cases on age and sex, and the full siblings (N\u00a0=\u00a02002) and spouses (N\u00a0=\u00a01220) of MND patients (i.e., relative controls). Conditional logistic regression models were used to estimate the risk of MND diagnosis in relation to previous CMDs, through comparing MND patients to population controls or relative controls. MND patients were followed from diagnosis to assess the role of pre-diagnostic CMDs on disease progression. A joint longitudinal-survival model was used to estimate risk of mortality (or use of invasive ventilation) in relation to CMDs after taking into account the longitudinal changes of ALS functional rating scale-revised (ALSFRS-R) in the time-to-event analysis. Hierarchical clustering with the Ward's linkage and a dissimilarity matrix created by Gower's method was used to identify clusters of MND patients with distinct phenotypes. Among the CMDs studied, a history of diabetes mellitus type 2 (OR 0.75; 95% CI 0.62, 0.93) or hypercholesterolemia (OR 0.82; 95% CI 0.71, 0.94) more than one year before diagnosis was associated with a lower risk for MNDs. The associations persisted for more than five years before MND diagnosis. MND patients with a history of any cardiovascular disease (HR 1.43; 95% CI 1.13, 1.81), arrhythmia (HR 1.42; 95% CI 1.04, 1.93), heart failure (HR\u00a01.79; 95% CI 1.02, 3.14), hypertension (HR 1.41; 95% CI 1.12, 1.77), or hypercholesterolemia (HR 1.28; 95% CI 1.01, 1.62) had an increased mortality risk, compared to others, after taking into consideration the longitudinal changes in ALSFRS-R. Cluster analysis identified two clusters of MND patients, where one cluster demonstrated higher age, worse functional status, and higher prevalence of CMDs at the time of diagnosis as well as a higher mortality and faster functional decline during follow-up, compared to the ones included in the other cluster. Diabetes mellitus type 2 and hypercholesterolemia were associated with a lower future risk of MND. On the other hand, most of the CMDs were indicative of a poor disease progression after an MND diagnosis.

Deficiency in this vitamin can lead to various health issues, including neurodegenerative diseases, due to its pivotal role in preserving cell membrane integrity and combating cellular oxidative damage. While its importance for overall health, including neurodegeneration, is acknowledged, the specific correlation between vitamin E deficiency and distinct ocular neurodegenerative disorders need to be further explored. This review delves into the molecular mechanisms of vitamin E in ocular neurodegenerative disorders; diabetic retinopathy, age-related macular degeneration, glaucoma, and cataracts, and emphasising the therapeutic implications drawn from existing evidence. Relationship between vitamin E and ocular neurodegenerative disorders is widely researched on, with its primary protective mechanisms attributed to its antioxidant and anti-inflammatory properties. However, studies on the supplementation of vitamin E among human subjects present mixed results, suggesting its complexities and variability depending on factors such as the specific disorder, disease stage, genetic differences, and form of vitamin E utilized. In conclusion, while vitamin E holds promise in mitigating ocular neurodegeneration through its antioxidant and anti-inflammatory properties, its supplementation's efficacy remains nuanced and context dependent. More research works are essential to elucidate its precise role and therapeutic potential in combating various ocular neurodegenerative disorders.",

Retrospective longitudinal cohort study, from Oct 2009 to Feb 2023. Tertiary Frontotemporal Dementia research clinic. A sample of 712 FTLD patients, 331 of whom had follow-up evaluation. LOI was assessed by interview with the primary caregiver. Univariate and multiple logistic regression and linear mixed models were used to estimate predictors and longitudinal changes over time associated with LOI. Voxel-based morphometry and structural covariance analyses of brain structural MRI images were implemented in Statistical Parametric Mapping. LOI was reported in 45% of patients (321/712, 95%CI = 41-49), with progressively increased prevalence from prodromal to severe dementia stages. LOI was more prevalent in the behavioural variant FTD, in the semantic variant of Primary Progressive Aphasia (svPPA) and FTD with Amyotrophic Lateral Sclerosis than in other phenotypes (all p-values<0.001). LOI severity increased over time only in patients with svPPA (\u03b2 = +0.59, p <0.001) and clustered with other behavioral symptoms (all p-values <0.05). Finally, LOI was significantly associated with greater atrophy in the right medial orbital gyrus (p <0.001 uncorrected). Structural covariance analysis demonstrated loss of negative correlation between right medial orbital gyrus and regions belonging to the Default Mode Network (DMN), such as the left precuneus and the left angular gyrus (p \u22640.05 family-wise error-corrected) in FTLD patients with LOI.

This article reviews the mechanism of action and formulation of semaglutide therapy, potential benefits, contraindications, adverse effects, and drug interactions. Oral and subcutaneous semaglutide therapies have shown effectiveness in improving glycemic control, weight loss, and reducing cardiovascular risks associated with diabetes mellitus. Semaglutide has also shown potential in being used as a therapeutic strategy in Alzheimer's disease due to its anti-neuroinflammatory effects and being used to treat polycystic ovary syndrome. However, semaglutide therapy is also associated with concerning adverse effects like acute pancreatitis, anesthetic risks like pulmonary aspiration or residual gastric content, acute kidney injury, acute gallbladder injury, nonarteritic anterior ischemic optic neuropathy and diabetic retinopathy. Contraindications of semaglutide include history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2, and pregnancy. Drug interactions to consider with semaglutide therapy include those also used in diabetes treatment, like metformin, as well as anti-psychotics, due to anti-psychotics associated weight gain. The findings of this article emphasize the need for a cross-disciplinary approach to understand the molecular mechanisms and clinical implications of semaglutide on patients with complex medical histories and treatment regimens. The potential anesthetic risks of semaglutide therapy warrant careful consideratiion with ethical concerns. Further studies can assess if there is a need to modify pre-operative guidelines to account for patient using semaglutide and how delayed gastric emptying and constitpation will affect surgical outcomes and complications.

Mural cell loss or malfunction has been associated with numerous diseases including diabetic retinopathy, stroke and amyotrophic lateral sclerosis. In this work, we investigate the role of CDC42 in mural cells in vivo, using the developing mouse retina as a model. In this study, we generated a mouse model for Cdc42 deletion in mural cells by crossing Pdgfrb-CreERT2 mice with Cdc42flox/flox mice. This model (Cdc42i\u0394MC) allowed us to investigate the role of CDC42 in pericytes and smooth muscle cells in the developing and adult retinal vasculature. We find that, during postnatal development, CDC42 is required in both, pericytes and smooth muscle cells to maintain proper cell morphology, mural cell coverage and distribution. During retinal angiogenesis, Cdc42-depleted pericytes lag behind the sprouting front and exhibit decreased proliferation. Consequently, capillaries at the sprouting front remain pericyte deprived, become dilated and are prone to increased vascular leakage. In addition, arteries and arterioles deviate from their normal growth directions and trajectory. While in the adult retina, mural cell coverage normalizes and pericytes adopt a normal morphology, smooth muscle cell morphologies remain abnormal and arteriolar branching angles are markedly reduced. Our findings demonstrate that CDC42 is required for mural cell migration and proliferation and suggest that mural cells are essential for normal morphogenesis and patterning of the developing retinal vasculature.",

We find that OPTN C-terminus truncation (OPTN\u2206C) causes late-onset neurodegeneration of retinal ganglion cells (RGCs), optic nerve (ON), and spinal cord motor neurons, preceded by a decrease of axonal mitochondria in mice. We discover that OPTN directly interacts with both microtubules and the mitochondrial transport complex TRAK1/KIF5B, stabilizing them for proper anterograde axonal mitochondrial transport, in a C-terminus dependent manner. Furthermore, overexpressing OPTN/TRAK1/KIF5B prevents not only OPTN truncation-induced, but also ocular hypertension-induced neurodegeneration, and promotes robust ON regeneration. Therefore, in addition to generating animal models for NTG and ALS, our results establish OPTN as a facilitator of the microtubule-dependent mitochondrial transport necessary for adequate axonal mitochondria delivery, and its loss as the likely molecular mechanism of neurodegeneration.",

These include amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration (FTLD), Alzheimer's disease (AD), chronic traumatic encephalopathy (CTE), and others. TDP-43 in the eye shows promise as a biomarker for these NDDs. Several studies have identified cytoplasmic TDP-43 inclusions in retinal layers of donors with ALS, FTLD, AD, CTE, and other conditions using immunohistochemistry. Our findings suggest that pathological aggregates of TDP-43 in the human retina are most prevalent in FTLD-TDP, ALS, and CTE, suggesting these diseases may provide the most reliable context for studying the potential of TDP-43 as a retinal biomarker. Animal model studies have been pivotal in exploring TDP-43's roles in the retina, including its nuclear and cytoplasmic localization, RNA binding properties, and interactions with other proteins. Despite these advances, more research is needed to develop therapeutic strategies. A major limitation of human autopsy studies is the lack of corresponding brain pathology assessments to confirm TDP-43 proteinopathy diagnosis and staging. Other limitations include small sample sizes, lack of antemortem eye pathology and clinical histories, and limited comparisons across multiple NDDs. Future directions for the TDP-43 as a retinal biomarker for NDDs include retinal tracers, hyperspectral imaging, oculomics, and machine learning development.",

        "40109357": "ID: 40109357\nTitle: Role of Tau Protein Hyperphosphorylation in Diabetic Retinal Neurodegeneration.\nAbstract: Diabetic retinal neurodegeneration (DRN) is an early manifestation of diabetic retinopathy (DR) characterized by neurodegeneration that precedes microvascular abnormalities in the retina. DRN is characterized by apoptosis of retinal ganglion cells (involves alterations in retinal ganglion cells [RGCs], photoreceptors, amacrine cells and bipolar cells and so on), reactive gliosis, and reduced retinal neuronal function. Tau, a microtubule-associated protein, is a key mediator of neurotoxicity in neurodegenerative diseases, with functions in phosphorylation-dependent microtubule assembly and stabilization, axonal transport, and neurite outgrowth. The hyperphosphorylated tau (p-tau) loses its ability to bind to microtubules and aggregates to form paired helical filaments (PHFs), which further form neurofibrillary tangles (NFTs), leading to abnormal cell scaffolding and cell death. Studies have shown that p-tau can cause degeneration of RGCs in DR, making tau pathology a new pathophysiological model for DR. Here, we review the mechanisms by which p-tau contribute to DRN, including insulin resistance or lack of insulin, mitochondrial damage such as mitophagy impairment, mitochondrial axonal transport defects, mitochondrial bioenergetics dysfunction, and impaired mitochondrial dynamics, Abeta toxicity, and inflammation. Therefore, this article proposes that tau protein hyperphosphorylation plays a crucial role in the pathogenesis of DRN and may serve as a novel therapeutic target for combating DRN.",
        "40278411": "ID: 40278411\nTitle: Lipid Metabolism and Statin Therapy in Neurodegenerative Diseases: An Endocrine View.\nAbstract: Background/aim: A growing body of evidence suggests a link between dyslipidemias and neurodegenerative diseases, highlighting the crucial role of lipid metabolism in the health of the central nervous system. The aim of our work was to provide an update on this topic, with a focus on clinical practice from an endocrinological point of view. Endocrinologists, being experts in the management of dyslipidemias, can play a key role in the prevention and treatment of neurodegenerative conditions, through precocious and effective lipid profile optimization. Methods: The literature was scanned to identify clinical trials and correlation studies on the association between dyslipidemia, statin therapy, and the following neurodegenerative diseases: Alzheimer's disease (AD), Parkisons's disease (PD), Multiple sclerosis (MS), and Amyotrophic lateral sclerosis (ALS). Results: Impaired lipid homeostasis, such as that frequently observed in patients affected by obesity and diabetes, is related to neurodegenerative diseases, such as AD, PD, and other cognitive deficits related to aging. AD and related dementias are now a real priority health problem. In the United States, there are approximately 7 million subjects aged 65 and older living with AD and related dementias, and this number is projected to grow to 12 million in the coming decades. Lipid-lowering therapy with statins is an effective strategy in reducing serum low-density lipoprotein cholesterol to normal range concentrations and, therefore, cardiovascular disease risk; moreover, statins have been reported to have a positive effect on neurodegenerative diseases. Conclusions: Several pieces of research have found inconsistent information following our review. There was no association between statin use and ALS incidence. More positive evidence has emerged regarding statin use and AD/PD. However, further large-scale prospective randomized control trials are required to properly understand this issue.",
        "40306255": "ID: 40306255\nTitle: Retinal alterations induced by amyotrophic lateral sclerosis: An analysis using optical coherence tomography.\nAbstract: In this study, we aimed to investigate retinal changes in a large cohort of amyotrophic lateral sclerosis (ALS) patients and healthy controls (HCs) to further elucidate their relationship with ALS. This was a cross-sectional observational study. We evaluated retinal layer thickness in 134 ALS patients and 66 HCs using optical coherence tomography (OCT). Particularly, we focused on the macular region and peripapillary retinal nerve fiber layer (p-RNFL). The examination of retinal layers in ALS patients revealed a significant change in the inner nuclear layer (INL), with a pattern of initial thickening followed by thinning, which correlated with disease stages, most notably in the inner nasal quadrant. Moreover, the p-RNFL in the temporal quadrant was thinner in ALS patients compared to HCs. In addition, ALS patients who developed bulbar symptoms exhibited marginally thinner p-RNFL in the temporal quadrant compared to those without bulbar symptoms. Interestingly, a thinner p-RNFL in the temporal quadrant did not correlate with faster disease progression. This study reveals notable changes in the INL and p-RNFL thickness in ALS patients, highlighting the intricate relationship between retinal changes and ALS progression. Despite these retinal alterations, no correlation with disease progression rate was observed. These findings suggest that while OCT shows potential in monitoring ALS, its role in predicting disease course requires further investigation with long-term longitudinal studies and diverse patient cohorts.",

A total of 122 eyes from 78 patients were included. Seventy-five eyes with an AL ranging between 26.00 and 27.49 mm comprised Group 1, and 47 with an AL of \u2265 27.50 mm comprised Group 2. Spectral-domain OCT was performed to measure the central macular thickness, subfoveal choroidal thickness (SCT) and swept-source OCTA was utilized to obtain the data on foveal avascular zone (FAZ) and vascular density (VD) values at the superficial and deep capillary plexuses (SCP and DCP), outer retina (OuR), and choriocapillaris (CC) segments. While no significant differences were found in terms of the mean superficial-FAZ and deep-FAZ areas (p=0.284 and p=0.952, respectively), there were significant differences between the groups in terms of the mean foveal VD in the SCP (p=0.001), the mean total VD (p=0.045) and foveal VD in the DCP (p<0.001), the mean foveal VD (p=0.019) and superior parafoveal VD in the OuR (p=0.008), the mean total (p=0.005), temporal parafoveal (p=0.034), inferior parafoveal (p=0.029), and nasal parafoveal VDs in the CC segments (p=0.005). The findings of the present study highlight the complex interplay between axial elongation and retinal microvasculature, suggesting that factors beyond mechanical stretching may contribute to these alterations. The variability in the existing literature on this topic arises from inconsistencies in the definition of high myopia, the use of different OCTA devices, and heterogeneous study populations. By including eyes with myopic maculopathy and employing axial length-based classification, this study provides a broad representation of high myopia. However, its retrospective design, single-center setting, and monoracial cohort represent limitations. Future large-scale, prospective studies involving diverse populations are needed to elucidate further the pathophysiology of high myopia and its impact on retinal and choroidal microcirculation. Our study revealed that high-myopic eyes with longer ALs exhibited increased total VD in the DCP and increased foveal VD in the SCP, DCP, and OuR segments, while they showed decreased total VD and temporal, inferior, and nasal parafoveal VDs in the CC segment compared to high-myopic eyes with shorter ALs.",

The MIROCALS study tested the hypothesis that low-dose interleukin-2 (IL-2LD) improves survival and function in ALS. In this randomised, double-blind, placebo-controlled trial, male and female riluzole-naive participants, with either a possible, laboratory-supported probable, probable, or definite ALS diagnosis (revised El Escorial criteria), aged 18-76 years, with symptom duration of 24 months or fewer, and slow vital capacity of 70% or more, underwent a riluzole-only 12-18 week run-in period before randomisation in a 1:1 ratio to either 2 million international units (MIU) IL-2LD or placebo by subcutaneous injection daily for 5 days every 28 days over 18 months. The primary endpoint was survival at 640 days (21 months). Secondary outcomes included safety, ALS Functional Rating Scale-Revised (ALSFRS-R) score, and biomarker measurements including regulatory T-cells (Tregs), cerebrospinal fluid (CSF)-phosphorylated-neurofilament heavy-chain (CSF-pNFH), and plasma and CSF-chemokine ligand 2 (CCL2). The primary endpoint analysis used unadjusted log-rank and Cox's model adjusted analyses using pre-defined prognostic covariates to control for the disease and treatment response heterogeneity. The study was 80% powered to detect a two-fold decrease in the risk of death by the log-rank test in the intention-to-treat (ITT) population, including all randomly allocated participants. MIROCALS is registered with ClinicalTrials.gov (NCT03039673) and is complete. From June 19, 2017, to Oct 16, 2019, 304 participants were screened, of whom 220 (72%) met all criteria for random allocation after the 12-to-18-week run-in period on riluzole. 136 (62%) of participants were male and 84 participants (38%) were female. 25 (11%) of the 220 randomly allocated participants were defined as having possible ALS under El Escorial criteria. At the cutoff date there was no loss to follow-up, and all 220 patients who were randomly allocated were documented as either deceased (90 [41%]) or alive (130 [59%]), so all participants were included in the ITT and safety populations. The primary endpoint unadjusted analysis showed a non-significant 19% decrease in risk of death with IL-2LD (hazard ratio 0\u00b781 [95% CI 0\u00b754-1\u00b722], p=0\u00b733), failing to demonstrate the expected two-fold decrease in risk of death. The analysis of the primary endpoint adjusted on prognostic covariates, all measured at time of random allocation, showed a significant decrease of the risk of death with IL-2LD (0\u00b732 [0\u00b714-0\u00b773], p=0\u00b7007), with a significant treatment by CSF-pNFH interaction (1\u00b70003 [1\u00b70001-1\u00b70005], p=0\u00b7001). IL-2LD was safe, and significantly increased Tregs and decreased plasma-CCL2 at all timepoints. Stratification on CSF-pNFH levels measured at random allocation showed that IL-2LD was associated with a significant 48% decrease in risk of death (0\u00b752 [0\u00b730-0\u00b789], p=0\u00b7016) in the 70% of the population with low (750-3700 pg/mL) CSF-pNFH levels, while in the 21% with high levels (>3700 pg/mL), there was no significant difference (1\u00b737 [0\u00b768-2\u00b775], p=0\u00b738). With this treatment schedule, IL-2LD resulted in a non-significant reduction in mortality in the primary unadjusted analysis. However, the difference between the results of unadjusted and adjusted analyses of the primary endpoint emphasises the importance of controlling for disease heterogeneity in ALS randomised controlled trials. The decrease in risk of death achieved by IL-2LD therapy in the trial population with low CSF-pNFH levels requires further investigation of the potential benefit of this therapy in ALS.

A systematic literature search was conducted on PubMed to identify studies evaluating the population pharmacokinetics of unbound cefazolin in patients. Subsequently, the selected models were used for external validation. Predictive bias was visually assessed by plotting the prediction errors (PEs) and relative PEs. Predictive precision was evaluated by calculating the mean absolute error (MAE), root mean square error (RMSE), and mean relative error (MRE). The predictive performance of the 4 unbound population pharmacokinetic models was evaluated using clinical data from 64 patients and 218 unbound concentration samples. The PEs for unbound cefazolin concentrations in the Komatsu model indicated a positive bias, while the RPEs demonstrated similar predictive distributions along the y = 0 line, regardless of the predicted values. In contrast, the other 3 models showed a negative bias for both PE and RPE at unbound cefazolin concentrations. The best MAE, RMSE, and MRE (%) values were 4.71, 9.02, and 30.2 in Komatsu et al.'s model, while the next best values were 11.5, 16.1, and 107.2 in Chung et al.'s model. Both models, which performed best regarding bias and accuracy, were also utilized in studies on unbound concentrations and the correlation between total concentrations and protein-binding sites. This study identified these models as the most suitable for predicting unbound cefazolin concentration profiles in surgical patients.",

Current diagnostic approaches, such as neuroimaging and cerebrospinal fluid biomarkers, are invasive, costly, and lack early diagnostic reliability. Recent studies highlight the potential of extracellular vesicles, particularly exosomes, derived from erythrocytes or red blood cells (RBCs), as emerging indicators of aging and age-associated diseases. Exosomes carry noncoding RNA, lipid, and protein molecules, and modulate cellular pathways at distant sites, providing neuroprotective and anti-inflammatory effects. In this study, we isolated RBC-derived exosomes of young and old mice. MicroRNA sequencing analysis revealed differential expression of several miRNA species between young and old mice. We report an upregulation of miR-125a-5p and a downregulation of miR-302a-5p in old mice that are potentially linked to neurodegenerative pathways. This study underscores the potential of RBC-derived exosomes as noninvasive biomarkers for NDDs.",

The purpose of this analysis is to examine the place of death for MND patients in the United States during the coronavirus disease 2019 (COVID-19) pandemic and to investigate the extent of specific comorbidities.MethodsWe obtained death certificate and associated comorbidities data for all U.S. MND deaths from 2018 to 2021 and conducted a population-based cross-sectional analysis of the deaths pre-COVID-19 (2018-2019) and during COVID-19 (2020-2021). We hypothesized that place of death and comorbidities associated with place of death for MND patients in the United States were altered during the COVID-19 pandemic in comparison to the 2 years period before the pandemic.ResultsWe analyzed 30\u2005066 MND deaths (14\u2005562 pre-COVID-19 and 15\u2005504 during COVID-19) aged 20 years and older. During COVID-19, MND deaths at home increased (54.4% vs 45.5% pre-COVID). Hispanic individuals had an increased likelihood of dying at home compared to a nursing home or hospice (OR\u2009=\u20091.57, 95%CI: 1.22-2.02), but a decreased likelihood compared to a hospital (OR\u2009=\u20090.61, 95% CI: 0.51-0.72). Among the top comorbidities listed, there was a 27.8% increase in diabetes mellitus and a 20.2% increase in essential hypertension during COVID-19. During COVID-19, diabetes mellitus was more commonly reported as a comorbidity for deaths occurring in hospitals (OR\u2009=\u20091.40, 95%CI: 1.03-1.89) or at home (OR\u2009=\u20091.26, 95%CI: 1.03-1.55), while essential hypertension was more commonly reported with deaths at home (OR\u2009=\u20091.17, 95%CI: 1.01-1.36).ConclusionOur analysis showed an increase in at-home MND deaths as well as certain comorbidities during the COVID-19 pandemic, suggesting MND patients had a higher likelihood of death from non-COVID-19 comorbidities.",

Adult male rabbits were randomly assigned to four experimental groups, each receiving a single intravenous injection of varying doses of alloxan and one control group. The safety and efficacy of alloxan in inducing diabetes were evaluated to determine the optimal dose. At 9\u2009weeks following injection with alloxan, retinal function was assessed using full-field electroretinography (ERG) and visual evoked potentials (VEPs). Retinal structure was examined in rabbits using spectral-domain optical coherence tomography (SD-OCT), Optos ultra-widefield (Optos UWF) false-color imaging, and widefield fundus fluorescein angiography (WF-FFA). Rabbits in the 80\u2009mg/kg alloxan group exhibited fewer complications, lower mortality, and a higher model success rate compared to other groups. At 9\u2009weeks post-injection, these rabbits demonstrated significantly elevated hemoglobin A1c and total cholesterol (p\u2009<\u20090.05) relative to controls. ERG revealed statistically significant reductions in oscillatory potential and b-wave amplitudes (p\u2009<\u20090.05), while VEP indicated decreased P2 amplitude (p\u2009<\u20090.001) and prolonged P2 latency (p\u2009<\u20090.05). SD-OCT, Optos UWF imaging, and WF-FFA demonstrated no significant changes in vascular abnormalities. Additionally, Hematoxylin and Eosin staining revealed retinal swelling (p\u2009<\u20090.05), and immunofluorescence confirmed glial activation and neuronal loss. A single intravenous injection of 80\u2009mg/kg alloxan effectively and safely induced DRN in rabbits, resulting in neural retina damage, thereby establishing this model as an ideal model for DRN research.",

AAV vector is the most popular viral gene delivery system in clinical delivery systems with unique and multiple advantages, such as tissue tropism, transduction specificity, long-lasting gene expression, low immune responses, and without host chromosome incorporation. Till now, four AAV-based gene therapy drugs have already been approved by the US Food and Drug Administration (FDA) or European Medicines Agency (EMA). Despite the success of AAV vectors, there are still some remaining challenges that limit further usage, such as poor packaging capacity, low organ specificity, pre-existing humoral immunity, and vector dose-dependent toxicity. In the present review, we address the different approaches to optimize AAV vector delivery system with a focus on capsid engineering, packaging capacity, and immune response at the clinical level. The review further investigates the potential of manipulating AAV vectors in preclinical applications and clinical translation, which emphasizes the challenges and prospects in viral vector selection, drug delivery strategies, immune reactions in cancer, neurodegenerative disease, retinal disease, SARS-CoV-2, and monkeypox. Finally, it forecasts future directions and potential challenges of artificial intelligence (AI), vaccines, and nanobodies, which emphasizes the need for ethical and secure approaches in AAV application.",

Among them, retina markers may hold promise due to the close retina-brain connection and non-invasive, portable detection methods. Thus, using optical coherence tomography (OCT), we investigated the link between baseline cell-level retinal features and future ALS risk. Participants from the UK Biobank underwent OCT scans to assess retinal layers, macula, and optic disc parameters. Follow-up commenced two years after the baseline period (2006-2010), during which ALS cases were identified using International Classification of Diseases (ICD) codes from medical and assessment records. Cox proportional hazards models were applied to examine the relationship between retinal markers and incident ALS. Over a median follow-up of 14.11 years, 70 ALS cases occurred among 53,824 participants (incidence 10.58 per 100,000 person-years). Most participants were White (94.6%), 44.8% male, with a median age of 58 years. After adjusting for demographics and comorbidities affecting the retina, a standard deviation (SD) decrease of 15.19 \u00b5m in photoreceptor layer (PRL) thickness was associated with a 19% (95% confidence interval [7, 29]; p\u2009=\u20090.002) increased risk of ALS, while a SD increase of 26.11 \u00b5m in retinal pigment epithelium (RPE) thickness corresponded to a 20% (95% CI [7, 34]; p\u2009=\u20090.002) higher risk. Sensitivity analyses excluding follow-ups of less than 4 and 6 years yielded consistent results. Subgroup analyses showed these findings were more pronounced in smokers. The main limitation of this study is its single time point observational design. A thinner PRL and thicker RPE may precede the clinical diagnosis of ALS, offering potential clues for early diagnosis and insights into the disease's pathogenesis.",

Unlike motor neurons, the RGC axons are accessible to high-resolution non-invasive optical imaging in their intraocular portion. A non-invasive in vivo retinal imaging biomarker can be valuable for amyotrophic lateral sclerosis (ALS) diagnosis and monitoring. We aim to assess the presence of inner retinal pathology in a mouse model of ALS and its possible progression with age. Transgenic SOD1G93A mice (n=8, 4M/4F) and age-matched controls (n=8, 4M/4F) underwent in vivo retinal imaging with confocal scanning laser ophthalmoscopy (cSLO) coupled with optical coherence tomography (OCT) at 20\u00a0weeks of age. Another group of SOD1G93A mice (n=20, 6M/14F) and age-matched controls (n=20, 6M/14F) underwent longitudinal in vivo retinal imaging with the same device. Each retinal imaging session included infrared reflectance (IR) and blue reflectance (BR) cSLO coupled with OCT. Hyperreflective puncta located in the retinal nerve fiber layer (RNFL) were counted in a blinded fashion in ALS and control mice. The number of puncta at 20\u00a0weeks of age in ALS mice was compared with controls using Wilcoxon test. The rates of increase of puncta number were analyzed using a Generalized Linear Mixed-Effect Model (GLMM) for genotype, time, and sex. IR-cSLO coupled with OCT revealed hyperreflective puncta located in the RNFL of ALS mice. IR-cSLO fundus imaging at the age of 20\u00a0weeks showed ALS mice had significantly higher number of puncta compared to controls (2.1\u00b12.3 vs 0.5\u00b10.8; (mean\u00b1SD), respectively, p=0.036). GLMM analysis showed both ALS mutation and age were significantly associated with the rate of increase of puncta number (p=0.000232 and p=0.000366, respectively). In addition, female ALS mice had a steeper increase of puncta compared to male ALS mice (0.21\u00b10.04 log number puncta/week vs 0.16\u00b10.04, respectively; p=0.037). Our findings demonstrate distinct inner retinal nerve fiber layer pathology, detected using cSLO coupled with OCT, which worsens over time. These findings support the potential of retinal imaging as a translationally relevant, non-invasive biomarker for ALS diagnosis or disease monitoring in humans.",

Assessment of BCVA was done using Snellen charts, and subjective refraction was done to achieve a BCVA for distance and near. Measurement of intraocular pressure (IOP) was done with Goldman applanation tonometry. Stereoscopic fundus examination was performed using a 90D lens to assess the status of the optic nerve and retina, ruling out any ocular pathology. The patients were then subjected to OCT scanning to measure optic nerve head and macular parameters. Optical coherence tomography was performed using CIRRUS\u2122 HD OCT (500-21822) (version 8.0.0.518) (Carl Zeiss Meditec, Dublin, CA, USA). The analyzed area was centered manually, and the absence of segmentation errors was confirmed for each scan. RE Avg RNFL and LE Avg RNFL showed weak correlations with ALSFRS, indicated by Pearson Correlation coefficients of 0.073 and -0.026, respectively. The p-values (0.637 and 0.86) suggested that these correlations were not statistically significant. RE Avg GCL and LE Avg GCL, on the other hand, exhibited moderate positive correlations with ALSFRS scores, with correlation coefficients of 0.337 (RE) and 0.389 (LE). These correlations were statistically significant, as indicated by p-values of 0.021 and 0.006, respectively, suggesting a substantial association between GCL thickness and ALS functional outcomes. All patients in our study were clinically diagnosed cases of ALS, as per the El Escorial criteria. Age group-wise analysis showed statistically significant thinning overall as well as quadrant-wise RNFL parameters in patients less than 50 years compared to age-matched controls, indicating that the pathological process occurring in larger motor neurons in ALS might also be happening in smaller sensory neurons of the retina, causing thinning, which was not due to age-related process. Although GCIPL thinning was occurring in our cases, though statistically not significant compared to control, the significant positive correlation observed between GCIPL and ALS functional outcome and between RNFL and GCIPL measurements highlighted the fact that though the axonal degeneration in retinal neurons might not be translating to the same extent in ganglion cells in ALS, the subtle thinning of GCIPL correlated strongly with functional disability in patients with ALS, implying better functional scores with higher values of GCIPL parameters. In summary, GCL measurements in both eyes showed a notable relationship with ALSFRS, whereas RNFL did not appear to correlate significantly.",

Despite their growing incidence, advancements in effective treatments remain limited, because of lack of knowledge for the aetiology of the diverse pathophysiology to design systematic therapies. Several studies highlight the role of neurotrophic factors (NTFs) as potential neuroprotective, regenerative therapies for these disorders. Although NTFs hold protective and regenerative potential for chronic neuroinflammatory and neurodegenerative conditions, major hurdles impair their clinical use, such as optimising the dosage of NTFs, minimising the invasiveness of delivery methods, overcoming blood-brain-barrier (BBB) impermeability and managing side effects. In the last two decades our group have synthesised and screened a large chemical library of steroidal analogues of dehydroepiandrosterone (DHEA), an endogenous steroid hormone, for their ability to mimic neurotrophin neuroprotective and neurogenic actions. Interestingly, DHEA was shown to interact with all neurotrophin receptors, acting most probably as an ancestral neurotrophin early in evolution. However, its chronic pharmacological use is questioned by its action as a major precursor of steroidogenesis. This review highlights the findings of numerous preclinical studies on these synthetic, non-toxic, BBB permeable DHEA derivatives, named microneurotrophins (MNTs), deprived of endocrine actions, activators of specific neurotrophin receptors. The multimodal actions of MNTs against neuronal death and activation of microglia, in addition to their beneficial effects in synaptogenesis and neurogenesis, place them as interesting lead molecules in the armamentarium of therapeutics for neurodegeneration.",

Although dopamine (DA) has demonstrated protective effects in various neurodegenerative diseases, its role in DRN is inadequately understood. This study provides evidence that DA can alleviate DRN impairment and elucidates the underlying mechanisms. Diabetes was induced in C57BL/6 mice through a single large dose injection of streptozotocin, and the dopamine precursor l-DOPA was administered via intraperitoneal injection daily for 2 weeks to therapeutically supplement dopamine levels. The results indicated that l-DOPA treatment significantly restored retinal thickness, enhanced the amplitude of oscillatory potentials, and alleviated retinal glial cell activation compared to diabetic mice. In vitro, DA treatment of SH-SY5Y cells under high-glucose stress led to a significant increase in superoxide dismutase activity, with a reduction in malondialdehyde levels, lipid peroxide, and iron ion concentration. Additionally, the expression of GPX4, SLC7A11, ferritin, Nrf2, and HO-1 proteins was upregulated, while the expression of NCOA4 was downregulated. Importantly, the protective effects of DA were significantly attenuated by the Nrf2 inhibitor ML385, confirming the involvement of the Nrf2/HO-1 pathway in DA's protective mechanism. These findings suggest that DA alleviates oxidative stress, reduces ferroptosis, and improves the retinal function in DRN through the activation of the Nrf2/HO-1 pathway, indicating that DA may represent a novel therapeutic strategy for treating DRN.",

Recent studies demonstrated that metabolic complications could develop as emerging complications among patients with SMA and long-term follow-up. Sarcopenia together with aberrant glucose and fatty acid metabolism can predispose those with SMA to develop diabetes and diabetic ketoacidosis. Here, we present a patient with SMA type III who presented with ketosis-prone diabetes as an initial presentation of diabetes. Pancreatic autoantibodies (anti-GAD and anti-IA2) and a monogenic diabetes genes panel revealed negative results. A polygenic risk score for type 2 diabetes revealed a low genetic risk for type 2 diabetes. After resolution of diabetic ketoacidosis, insulin therapy was successfully discontinued within 1 month after discharge and the patient has been treated with metformin in combination with thiazolidinedione. The possibility of metabolic abnormalities in patients with SMA should be considered among patients who live well into adulthood. Sarcopenia together with alterations in fatty acid and ketone metabolism could lead to ketosis-prone diabetes as an initial presentation of diabetes among patients with SMA.",

It encompasses the essential features of apoptosis, necroptosis, and pyroptosis and combines elements from each process. PANoptosis contributes to the development of various diseases, including bacterial and viral infections, tumors, inflammatory diseases, and neurodegenerative diseases, which offers insights into the pathological mechanisms of these diseases and potential treatments. Retinal ganglion cells (RGCs) are nerve cells located in the final segment of the retina, which belongs to the central nervous system. The loss of RGCs caused by various diseases cannot be reversed. Consequently, safeguarding RGCs from loss is a crucial goal in the treatment of diseases that cause RGCs death (such as trauma, glaucoma, and diabetic retinopathy). Research on the multiple modes of death of RGCs has made some progress and, recently, PANoptosis has been observed during the death of RGCs in different models. In this article, we first give an overview of PANoptosis and summarize the fundamental mechanisms and crosstalk between apoptosis, necroptosis, and pyroptosis, as well as the characteristics of these three modes of cell death that occur in RGCs. Finally, we discuss the current status of research on PANoptosis in neurons and RGCs to establish a theoretical basis for the mechanism of PANoptosis as a novel target for safeguarding RGCs from loss.",

Elevated levels of plasma glial fibrillary acidic protein (GFAP), a marker of astrogliosis, have been demonstrated early in the course of Alzheimer's Disease. In this study, we measured GFAP levels in the aqueous and vitreous humors and plasma of 79 participants undergoing vitrectomy surgery for retinal disease and correlated them with subject Mini Mental Status Exam (MMSE) and Trail Making Test part b (TMT-b) scores. Measured GFAP concentrations were higher in vitreous and aqueous than in plasma. Levels of GFAP within the aqueous and vitreous were correlated (r\u2009=\u20090.6; p\u2009<\u20090.0001); however, there was no association between GFAP levels in either ocular fluid and plasma. There was no significant correlation between GFAP levels in any of the measured ocular fluids and cognition as measured by MMSE and TMT-b scores. In plasma, higher GFAP levels were associated with lower TMT-b, but not MMSE, scores. Given that elevated GFAP levels are associated with a variety of vitreoretinal diseases, future studies evaluating its use as a potential biomarker for dementias should concentrate on recruiting subjects without a history of ocular disease.",

Insulin treatment decreases neurodegeneration and intranasal insulin has been shown to reach the central nervous system in neurodegenerative diseases like dementia. We tested the hypothesis that intranasal insulin can decrease retinal neurodegeneration using the C57BL/KsJ-db/db transgenic diabetic (db/db) mouse model. Compared to the non-diabetic wildtype mice given intranasal saline, we observed decreased electroretinogram b-wave and oscillatory potential amplitudes in db/db mice treated with intranasal saline but not in the db/db mice treated with 2 units of intranasal insulin daily over 10 weeks. When compared to the non-diabetic intranasal saline control, we also observed decreased outer retinal thickness in the db/db mice given intranasal saline but this effect was attenuated in the db/db mice treated with intranasal insulin. GFAP immunoreactivity and caspase cell count were similarly elevated in the db/db mice treated with intranasal saline but not intranasal insulin. Mean blood glucose measurements increased 30 minutes after both intranasal saline and insulin treatment. Transcriptomic analysis revealed downregulation of inflammatory and apoptotic genes in the retina of db/db mice treated with intranasal insulin when compared to saline. In summary, treatment with intranasal insulin prevents the depression of b-waves and oscillatory potentials, decreases the attenuation of outer retinal thickness, reduces caspase cell count and GFAP immunostaining, and downregulates the transcription of inflammatory and apoptotic genes in the retina of db/db mice without exerting peripheral glucose lowering effects. Taken together, our results suggest that intranasal insulin can reduce neurodegeneration in diabetic retinopathy by improving retinal neuronal function, decreasing reactive gliosis and cell death, and modulating the expression of inflammatory and apoptotic genes.",

However, the specific cell types involved in disease development and the molecular mechanisms driving their responses have not yet been fully clarified, impeding the creation of effective therapeutic strategies. Recent advancements in single-cell or single-nuclei transcriptomic technologies have provided a systematic approach to profile transcript-level alterations at single-cell resolution, allowing for an in-depth analysis of diabetes-induced retinal transcriptional changes across various animal models for DR. Here, in the context of research funded by the American Diabetes Association Pathway to Stop Diabetes program, we discuss the cell-type-specific responses in the neural retina identified through single-cell transcriptomic analyses. We emphasize new insights into neural retinal responses, potential therapeutic targets, and the limitations and unresolved topics that warrant further investigation. This article is part of a series of perspectives that report on research funded by the American Diabetes Association Pathway to Stop Diabetes program. Single-cell transcriptomics provides a powerful solution for dissecting diabetes-induced cell-type-specific responses in mammalian retina. This article summarizes key findings from recent single-cell transcriptomic studies regarding the mechanisms of diabetic retinopathy, with a particular emphasis on the neural retina. Specific retinal neuronal types/subtypes exhibit heightened sensitivity to diabetes at the transcriptional level.

Given the distinct microvascular pathology in diabetes, this study evaluated the system's applicability in diabetic ERMs and compared structural and vascular features of diabetic and idiopathic ERMs using OCT and OCT-angiography (OCT-A). This retrospective study included 142 eyes with diabetic ERM, idiopathic ERM, and healthy controls. All subjects underwent comprehensive ophthalmic examination, OCT, and OCT-A imaging. ERMs were staged using Govetto et al.'s classification. Correlations between visual acuity (VA), ERM stage, OCT metrics, and OCT-A parameters were analyzed. The macular vessel density ratio (MVR) was also calculated. Ectopic inner foveal layer (EIFL), microcystoid changes, and retinal layer thicknesses were comparable across stages, with EIFL increasing as stages advanced in both groups. EIFL and outer foveal thickness showed no significant group differences, but EIFL was consistently thinner in diabetic cases. Diabetic ERMs had lower vessel densities (VD) and significantly reduced choriocapillaris flow area. Only in the diabetic group were strong correlations observed between outer retinal layer values and VD, as well as between VA, choriocapillaris flow, retinal thickness, and deep macular VD. Although Govetto's OCT-based classification aligns with structural progression in both ERM types, it does not reflect the vascular alterations seen in diabetic ERMs. These findings suggest that structural staging alone may be insufficient in diabetic cases. Awareness of vascular differences and integration of OCT-A parameters may improve interpretation and guide prognosis in diabetic ERMs.",

Dysregulation of TPPP3 is implicated in neurodegenerative diseases such as Parkinson's disease and diabetic retinopathy. Unlike TPPP1, which is oligodendrocyte-specific, TPPP3 was reported to primarily promote neuronal regeneration and serve as a therapeutic target for neurodegenerative diseases such as Parkinson's disease and glaucoma. Beyond the nervous system, TPPP3 has been linked to oncogenesis and tissue regeneration, suggesting potential roles in tumor suppression and wound healing. This review summarizes neuronal functions of TPPP3, therapeutic opportunities, and future research directions. Understanding the molecular mechanisms underlying function of TPPP3 could provide valuable insights into its therapeutic applications in neuroprotection.",

This condition is marked by neuronal apoptosis and glial activation. M\u00fcller glia are retinal cells highly susceptible to diabetic metabolic stress that may undergo ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation. However, the role of ferroptosis in DNR pathogenesis remains undefined. In this study, we investigated M\u00fcller cell injury under high-glucose and palmitic acid (HGP) conditions. The retinal tissues were obtained from normal rabbits and alloxan-induced diabetic rabbits. HGP exposure significantly reduced M\u00fcller cell viability, induced cell cycle arrest, and elevated proinflammatory cytokines. Ultrastructural analysis revealed mitochondrial damage, accompanied by decreased glutathione (GSH) and increased malondialdehyde (MDA), ferrous iron (Fe2+), and reactive oxygen species (ROS) levels. RNA sequencing (RNA-Seq) identified SQSTM1 as a ferroptosis-related differentially expressed gene, which was significantly upregulated in HGP-treated cells. In vivo, DNR rabbits exhibited oxidative stress, iron dysregulation, and elevated SQSTM1 expression that colocalized with GFAP+ M\u00fcller cells. Single-cell RNA-Seq of human proliferative diabetic retinopathy (PDR) retinas confirmed elevated SQSTM1 expression in M\u00fcller cells compared to healthy control (HC) retinas. Mechanistically, SQSTM1 knockdown attenuated ferroptosis, oxidative stress, and HGP-induced injury, while its overexpression exacerbated ferroptosis via ACSL4 upregulation. Overall, our findings suggest that SQSTM1 may serve as a critical mediator linking M\u00fcller cell dysfunction and ferroptosis in DNR pathogenesis, offering a novel potential therapeutic target.",

Accurate protein modification is essential for maintaining oxidative stress, apoptosis, and cellular senescence in the organism. The regulation of protein homeostasis involves three biological processes: endoplasmic reticulum stress (ERS), endoplasmic reticulum autophagy (ERPA), and endoplasmic reticulum-associated degradation (ERAD). Retinal degenerative disease (RDD) is a blinding eye conditions that cause severe vision loss. Although the pathogenesis of RDD is complex, previous data suggest that ER plays a key role in the development of a variety of eye diseases, such as diabetic retinopathy (DR), glaucoma, age-related macular degeneration (AMD), and axial myopia. Based on this, this paper will review the process of endoplasmic reticulum quality control (ERQC) and summarize the pathological mechanisms of the aforementioned eye diseases from the perspective of ERQC, providing new insights for the treatment of RDD.",

As the brain is one of the most energy-demanding organs, neurons are particularly susceptible to mitochondrial dysfunction that arises with aging. Key features of mitochondrial aging include impaired mitochondrial dynamics, reduced mitophagy, increased production of reactive oxygen species (ROS), and accumulation of mitochondrial DNA (mtDNA) mutations. These alterations dramatically compromise neuronal bioenergetics, disrupt synaptic integrity, and promote oxidative stress and neuroinflammation, paving the path for the development of neurodegenerative diseases. This review also examines the complex mechanisms driving mitochondrial aging in the central nervous system (CNS), including the disruption of mitochondrial-organelle communication, and explores how mitochondrial dysfunction contributes to neurodegenerative diseases, such as Alzheimer's, Parkinson's, Huntington's, and amyotrophic lateral sclerosis. By synthesizing current evidence and identifying key knowledge gaps, we emphasize the urgent need for targeted strategies to restore mitochondrial function, maintain cognitive health, and delay or prevent age-related neurodegeneration.",

This study aimed to identify novel genetic variants associated with DR and evaluate interactions between polygenic risk scores (PRS) and lifestyle factors in a Korean diabetic cohort. Methods: After excluding subjects with non-diabetic retinopathy eye diseases (n = 2519), we analyzed data from 50,361 non-diabetic controls, 4873 diabetic participants without retinopathy (DM-NR), and 165 with diabetic retinopathy (DM-DR). We conducted genome-wide association studies comparing DM-NR and DM-DR groups, performed generalized multifactor dimensionality reduction (GMDR) analysis for epistatic interactions, developed unweighted PRS models, and examined PRS-lifestyle interactions using two-way analysis of covariance. Results: DM-DR prevalence showed strong associations with metabolic syndrome and its components. Five novel genetic variants were identified: ABCA4_rs17110929, MMP2-AS1_rs2576531, FOXP1_rs557869288, MRPS33_rs1533933, and DRD2_rs4936270. A significant three-way epistatic interaction among the first three variants was discovered through GMDR analysis. High-PRS individuals (scores 5-6) showed a 49-fold higher odds ratio of DM-DR compared to low-PRS individuals (scores 0-2; p < 0.0001). MAGMA analysis revealed enrichment in pathways related to protein degradation, vascular function, and neuronal signaling, with predominant upregulation in brain tissues. Significant PRS \u00d7 lifestyle interactions were identified for fruit intake, coffee consumption, alcohol intake, eating duration, and physical activity, with lifestyle factors modifying genetic risk effects (all p < 0.003). Conclusions: These findings identify novel genetic variants and epistatic interactions in DM-DR pathogenesis, supporting the use of PRS-based risk stratification for intensive monitoring and personalized lifestyle interventions. The discovery of brain tissue-enriched pathways suggests DM-DR shares mechanisms with neurodegenerative diseases, expanding therapeutic targets beyond traditional vascular approaches.",

This study was part of the population-based Shiraz pediatric eye study. Of 2400 children aged 6-12 years invited, 480 were randomly selected for optical biometry and macular spectral-domain OCT (SD-OCT) imaging. Finally, 431 OCT scans from children with medium axial length (AL; 21.5-26.5 mm) were analyzed. The OCT device automatically segmented seven retinal sublayers, and their thickness was measured across Early Treatment Diabetic Retinopathy Study (ETDRS) subfields. Thickness in the central 1-mm subfield was assessed by gender and age groups (6-9 vs. 10-12 years), adjusted for AL. Regression analysis examined the impact of age, sex, and AL on retinal sublayer thickness. Only data from the right eye were used. The mean age of participants was 9.12 \u00b1 1.59 years (range, 6-12), with 254 (58.9%) being girls. The mean AL was 22.91 \u00b1 0.71 mm, and the mean foveal thickness was 258 \u00b1 8 \u00b5m. A normative database was created for the total retinal thickness and the seven retinal sublayers across the nine ETDRS subfields. Boys had longer globes (by approximately 0.4 mm; P < 0.001) and thicker foveae (by about 5 \u00b5m; P = 0.001) compared to girls. Among the seven sublayers studied, boys had a thicker ganglion cell complex layer (P = 0.014) and outer nuclear layer (ONL; P = 0.012), while girls had a thicker retinal pigment epithelium (RPE; P = 0.029). The inner nuclear layer and outer plexiform layer showed no significant differences (P = 0.075 and P = 0.810, respectively). The mean AL was 22.78 \u00b1 0.68 mm in the 6-9 age group and 23.10 \u00b1 0.72 mm in the 10-12 age group (P < 0.001). The older age group (10-12 years) exhibited thicker ONL (P = 0.009) and RPE (P = 0.002) layers compared to the younger group. This study provides normative data for macular sublayer thickness in Iranian children aged 6-12 years using Heidelberg SD-OCT. Boys had longer ALs and thicker maculae, while girls had a thicker RPE layer. Older children had longer globes and thicker retinas, mainly due to increased ONL and RPE thickness.",

In the 2021 meeting \"Solving Neurodegeneration,\" (detailed in Mol Neurodegeneration 17(1), 2022) the team examined the failures of investigational monotherapies, issues with translatability, and other significant challenges faced when working with neurodegenerative disease models. They emphasized the need for novel, humanized models and proposed identifying commonalities across neurodegenerative diseases to support the creation of pan-neurodegenerative disease therapies. Since then, the fourth Catalyst for a Cure team (CFC4) was formed to explore commonalities between glaucoma and other neurodegenerative diseases. This review summarizes outcomes from the 2023 \"Solving Neurodegeneration 2\" meeting, a forum for CFC3 and CFC4 to share updates, problem solve, plan future research collaborations, and identify areas of unmet need or opportunity in glaucoma and the broader field of neurodegenerative disease research. We summarize the recent progress in the field of neurodegenerative disease research and present the newest challenges and opportunities moving forward. While translatability and disease complexity continue to pose major challenges, important progress has been made in identifying neuroprotective targets and understanding neuron-glia-vascular cell interactions. New challenges involve improving our understanding of the disease microenvironment and timeline, identifying the optimal approach(es) to neuronal replacement, and finding the best drug combinations and synergies for neuroprotection. We propose solutions to common research questions, provide prescriptive recommendations for future studies, and detail methodologies, strategies, and approaches for addressing major challenges at the forefront of neurodegenerative disease research. This review is intended to serve as a research framework, offering recommendations and approaches to validating neuroprotective targets, investigating rare cell types, performing cell-specific functional characterizations, leveraging novel adaptations of scRNAseq, and performing single-cell sorting and sequencing across neurodegenerative diseases and disease models.

OPTN dysfunction has been implicated in the pathogenesis of several diseases, such as primary open angle glaucoma (POAG), amyotrophic lateral sclerosis (ALS). While mutations of OPTN seem to be predominantly loss-of-function in ALS, only gain-of-function mechanisms have been reported in POAG. Here, we demonstrate that OPTN knockout in the retina contributes to short-term astrogliosis, retinal ganglion cell (RGC) loss and long-term microglial activation. Moreover, OPTN loss of function does not exacerbate RGC death induced by ocular hypertension. Integrated bioinformatics and immunofluorescence analyses reveal that OPTN dysfunction leads to neuropeptide Y (NPY) downregulation and CHOP upregulation. Overexpression of wild-type OPTN in a hypertension glaucoma model prevents the RGC loss and attenuates microglial activation. Together, our findings highlight a neuroprotective role for OPTN as a key neuroimmune modulator.",

This study used summary data-based MR to analyze the correlation between plasma protein levels and three RND, with protein data derived from two independent large-scale proteomics datasets. Potential drug targets were identified using Bayesian colocalization, followed by MR analysis, sensitivity testing, and external validation. Drug prediction and molecular docking were conducted to evaluate the druggability of the target proteins.

The results included three proteins related to diabetic retinopathy (ICAM1, GCKR, WARS), two proteins related to age-related macular degeneration (WARS, BRD2), and two proteins related to glaucoma (SVEP1, NPTXR). Additionally, drug prediction and molecular docking indicated that five drugs (fenofibrate, trofinetide, ticagrelor, lifitegrast, acetaminophen) effectively bound to the target proteins.

However, how haploinsufficiency for TBK1 leads to age-related neurodegeneration remains unresolved. Here, we utilize sets of isogenic induced pluripotent stem cells (iPSCs) with loss of TBK1 or loss of optineurin (OPTN) for quantitative global proteomics and phospho-proteomics in both stem cells and excitatory neurons. We found that TBK1 sustains the abundance and phosphorylation of its interacting adapter proteins, AZI2/NAP1, TANK, and TBKBP1/SINTBAD. Moreover, TBK1 regulates the phosphorylation of endo-lysosomal proteins, such as GABARAPL2, the late-endosome GTPase RAB7A, and selective autophagy cargo receptor proteins-including novel phospho-sites in p62/SQSTM1-in neurons.

Although lowering intraocular pressure (IOP) remains the only proven treatment, glaucoma arises from a complex interplay of genetic, local, and systemic factors-including oxidative stress, vascular dysregulation, mitochondrial dysfunction, and neuroinflammation. Emerging evidence suggests that modifiable lifestyle factors may influence these pathogenic pathways. In this review, higher dietary nitrate from leafy greens is consistently associated with lower primary open-angle glaucoma risk, aligning with nitric-oxide-mediated endothelial support and more stable ocular perfusion pressure. Flavonoids (anthocyanins and flavanols), carotenoids (lutein/zeaxanthin), and B vitamins have strong biological rationale for glaucoma prevention but have limited support from long-term, large population-based studies. The effect of polyunsaturated fats on glaucoma remains inconsistent and warrants source-(plant vs. animal) and substitution-based analyses. Consistent protective effects of aerobic exercise and high-quality sleep may be associated with favorable metabolic profiles and ocular perfusion, potentially mitigating retinal ganglion cell loss. Conversely, smoking and alcohol use are frequently coupled with poorer diet quality (e.g., lower vegetable intake) and heightened oxidative stress, which may exacerbate glaucomatous neurodegeneration. However, much of the current literature is constrained by cross-sectional designs, reliance on self-reported food frequency questionnaires, and insufficient use of structural endpoints such as retinal nerve fiber layer imaging. This review focuses on the potential of lifestyle modification and future directions in prevention and treatment strategies for glaucoma, highlighting the need for large-scale, multi-ethnic, genotype-stratified longitudinal studies and randomized controlled trials to establish causality and define optimal intervention strategies.",

It presents significant treatment challenges due to its inherent resistance to conventional fractionated radiotherapy (CFRT). Single high dose radiation therapy (SDRT) has promise for the treatment of radioresistant sarcomas, especially those characterized with extensive vascularity. However, its clinical application is severely constrained by toxicity to adjacent critical tissues. Radiosensitizers can enhance tumor cell susceptibility to radiation-induced DNA damage, improving therapeutic efficacy and potentially reducing collateral toxicity. Monotherapies targeting tumor vasculature alone in solid tumors have shown limited success as radiosensitizers in clinical settings. This highlights the importance of compounds that can simultaneously target both tumor cells and its associated microvasculature to maximize the therapeutic outcome to SDRT. Riluzole, the FDA-approved drug for Amyotrophic Lateral Sclerosis, is currently under investigation as a therapeutic agent for osteosarcoma. Riluzole acts to inhibit glutamate release, reduce glutathione levels in cancer cells, and mitigate tumor angiogenesis, positioning it as a potent radiosensitizing agent for the treatment of osteosarcoma. We hypothesize that Riluzole enhances osteosarcoma radiosensitivity to SDRT by simultaneously targeting intrinsic tumor radioresistance and pro-angiogenic signaling. Our findings demonstrate that Riluzole radiosensitizes osteosarcoma cells in vitro by reducing clonogenic survival and enhancing apoptosis. Mechanistically, Riluzole potentiates irradiation-induced reactive oxygen species (ROS) production, induces G2/M phase cell cycle arrest, inhibits DNA repair, and thereby amplifies radiation-induced DNA damage. Additionally, Riluzole suppresses radiation-induced Vascular Endothelial growth factor A (VEGFA) expression indicating its ability to overcome endothelial cell mediated radioresistance. Collectively, these results establish Riluzole as a promising radiosensitizer for osteosarcoma, with the potential to improve SDRT efficacy by overcoming both tumor-intrinsic and microvasculature-mediated radioresistance.",

Increasing evidence implicates eCBS dysregulation in both addiction and neurodegenerative (ND) disorders, suggesting overlapping molecular and cellular mechanisms underlying these conditions. This review synthesizes recent advances in understanding how eCBS components-cannabinoid receptors (CB1 and CB2), endogenous ligands (anandamide and 2-arachidonoylglycerol), and their metabolic enzymes-modulate dopaminergic and glutamatergic signaling within reward and reinforcement circuits. Chronic exposure to drugs of abuse, including alcohol, opioids, cocaine, and methamphetamine, perturbs eCBS homeostasis, promoting oxidative stress, neuroinflammation, excitotoxicity, mitochondrial dysfunction, and protein aggregation-pathological features common to Alzheimer's, Parkinson's, Huntington's, and amyotrophic lateral sclerosis. These overlapping mechanisms disrupt neuronal integrity and contribute to progressive neurotoxicity, highlighting shared pathogenic pathways between addiction and neurodegeneration. Despite these advances, critical gaps remain in delineating how substance-induced eCBS alterations precipitate neurodegenerative cascades. Addressing these gaps will be essential for harnessing the eCBS as a therapeutic target to mitigate addiction-driven neurotoxicity and age-related cognitive decline.",

However, accumulating evidence indicates that retinal neurodegeneration is also crucial in DR pathogenesis. Retinal ganglion cells (RGCs), the output neurons of the retina, are particularly vulnerable to diabetic stress. Cellular senescence has been implicated in diabetes-related tissue damage, but its contribution to RGC degeneration remains unclear. We hypothesized that diabetes contributes to retinal neurodegeneration by inducing senescence in RGCs. Methods In streptozotocin (STZ)-induced diabetic mice, retinal function was assessed via full-field electroretinography (ERG), and molecular changes were evaluated in senescence markers. The expression of p16INK4a and monocyte chemotactic protein-1 (MCP-1) in retinal tissue was evaluated by enzyme-linked immunosorbent assay (ELISA) and quantitative real-time polymerase chain reaction (qRT-PCR), and the localization of p16INK4a was confirmed by immunostaining. To explore the direct effects of senescence, primary RGCs isolated from rat retina were exposed to oxidative stress or treated with the CDK4/6 inhibitor palbociclib. The isolated RGCs were analyzed via senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) staining and live-cell neurite imaging. Results The STZ-induced diabetic mice exhibited significant hyperglycemia without weight loss. ERG revealed markedly reduced amplitudes of the a-wave, b-wave, and oscillatory potentials, indicating impaired retinal neural function. Molecular analyses revealed significant upregulation of MCP-1 and p16INK4a at mRNA and protein levels. Immunostaining demonstrated p16INK4a co-expression in a subset of NeuN-positive cells within the ganglion cell layer, suggesting RGC senescence. Palbociclib-induced senescence (confirmed by SA-\u03b2-gal positivity) in vitroresulted in progressive neurite shortening in RGCs. Similarly, oxidative stress induced by antioxidant-free culture conditions caused neurite degeneration, highlighting the dual contributions of oxidative stress and senescence to RGC injury. Conclusions Cellular senescence was identified as a critical mechanism underlying RGC dysfunction in diabetes. Diabetes was found to induce retinal senescence and senescence-associated secretory phenotype activation, with RGCs exhibiting senescence-associated changes. Moreover, oxidative stress and pharmacologically induced senescence directly impaired RGC morphology and function in vitro. These results expanded our understanding of DR from a solely vascular disorder to a neurodegenerative disease, providing mechanistic insights into the role of senescence in retinal aging and neuronal susceptibility in diabetes.",
        "41422089": "ID: 41422089\nTitle: The Ku80-p53-SIRT1 axis in DNA damage response contributes to sporadic and familial ALS and FTD.\nAbstract: Although TDP-43 pathology is found in most sporadic and familial ALS and FTD cases, other shared pathogenic mechanisms remain largely unknown. Here we show that SIRT1 levels are decreased and acetylated p53 levels are increased in iPSC-derived neurons from sALS patients and with the FTD3-causing CHMP2B mutation. Ectopic expression of SIRT1 in these patient neurons rescues neurodegeneration and reduces acetylated p53 levels. DNA damage is elevated in both sALS and FTD3 neurons, leading to increased phosphorylation of p53 at Serine 15 and elevated levels of Ku80. Knockdown of either p53 or Ku80 rescues neurodegeneration and increases SIRT1 levels in these neurons. Moreover, ectopic expression of SIRT1 or genetic knockdown of either p53 or Ku80 suppresses retinal neurodegeneration caused by FTD3-associated mutant CHMP2B protein in an in vivo Drosophila model. These findings identify a dysregulated SIRT1-p53 feedback loop as a common pathogenic mechanism and promising therapeutic target in both sporadic and familial ALS/FTD.",
        "41468784": "ID: 41468784\nTitle: Neuropeptide Y at the crossroads of neurodegeneration: Mechanistic insights and emerging therapeutic strategies.\nAbstract: Neuropeptide Y (NPY), a widely distributed and highly conserved neuropeptide, plays a central role in the regulation of diverse physiological processes, including stress responses, energy homeostasis, vascular tone, and immune modulation, via activation of its receptor subtypes. Beyond its physiological roles, the dysregulation of NPY expression has been documented in several neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, Huntington's disease, amyotrophic lateral sclerosis, Machado-Joseph disease, and retinal disorders such as diabetic retinopathy and glaucoma. These alterations in NPY levels and receptor activity highlight its potential not only as a biomarker for disease progression but also as a promising therapeutic target. Previous evidence revealed that NPY exerts neuroprotection by alleviating excitotoxicity, oxidative stress, mitochondrial dysfunction, and neuroinflammation while concurrently facilitating neurogenesis, synaptic plasticity, and cellular resilience. NPY activates receptor-mediated intracellular signaling cascades like PI3K/Akt, MAPK/ERK, and p38K, that control cellular survival, proteostasis, and inflammation and thereby influence disease trajectories. Understanding NPY operation with these mechanisms can unveil new avenues for targeted therapy. Current insights into the complex roles of NPY in neurodegeneration are discussed in this review, and their implications in diagnostic and treatment strategies are addressed.",

We previously used a chronic low light (CLL) exposure to model slow photoreceptor degeneration in adult zebrafish. Here, we investigate transcriptional, morphological, and functional responses of microglia in the CLL model. Microglia-specific gene expression analysis was mined from our previously reported 3' RNA-seq data performed at 8 time points during 28 days of CLL exposure. Morphological changes were performed on retinas collected at various time points using immunohistochemistry. Microglial inhibition was accomplished pharmacologically with dexamethasone and genetically using the irf8-/- mutant fish. Finally, we returned the CLL-treated fish to normal light/dark conditions to test whether photoreceptors could recover in the context of chronic stress. CLL induced dynamic, time-dependent upregulation of microglia-specific genes consistent with pro-inflammatory and pro-resolving function. Dexamethasone treatment reduced microglial numbers and exacerbated rod and cone outer segment damage, whereas irf8-/- mutants exhibited partial protection against photoreceptor damage. Notably, despite prolonged stress and damage during the CLL exposure, photoreceptor outer segments returned to near-baseline morphology after 28 days of normal light/dark recovery conditions. Overall, these findings suggest that microglial function in chronic retinal injury is context-dependent as pharmacological and genetic methods of inhibition produced contrasting outcomes depending upon microglial polarization.",

Following assay validation, we used enzyme-linked immunosorbent assay to measure CSF TMEM119 in 174 patients from six diagnostic groups: Alzheimer's disease (AD, n\u00a0=\u00a035), amyotrophic lateral sclerosis (ALS, n\u00a0=\u00a033), cerebral microangiopathy (CM, n\u00a0=\u00a025), frontotemporal lobar degeneration (FTLD, n\u00a0=\u00a028), Lewy body diseases (n\u00a0=\u00a021), and non-neurodegenerative controls (n\u00a0=\u00a033). CSF TMEM119 levels were elevated in the AD group compared to the control (p\u00a0=\u00a00.004), CM (p\u00a0=\u00a00.005), and FTLD (p\u00a0=\u00a00.023) groups. Levels were higher in both mild cognitive impairment (MCI-AD) and dementia (ADD) subgroups when compared to controls. For the discrimination of AD from controls, the area under the curve (AUC) was 0.78. Our results indicate that CSF TMEM119 may have potential as a biomarker representing microglial involvement in early and later stages of AD. Elevated levels of TMEM119 were observed in the CSF of patients with AD.Increased CSF TMEM119 was seen in MCI-AD patients compared to controls.Elevated levels in MCI-AD underscore early microglial involvement in AD.In the AD group, an association was found between CSF TMEM119 and CSF total tau.CSF TMEM119 may provide valuable information on neuroinflammation.",

Recent research has illuminated the pivotal roles of RNA-binding proteins (RBPs) and non-coding RNAs (ncRNAs), notably microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), in the molecular pathogenesis of age-related neurodegeneration. RBPs orchestrate RNA metabolism and engage extensively with miRNAs and lncRNAs to modulate gene expression at the post-transcriptional level. Dysregulation of these interactions precipitates pathological phenomena such as protein misfolding, stress granule formation, and disrupted RNA processing, thereby exacerbating neuronal dysfunction and death. Specific miRNAs have been implicated in regulating key neurodegenerative biomarkers, including tau and amyloid-\u03b2 in AD, motor neuron maintenance in ALS, and survival pathways in HD. Elucidating the intricate interplay between RBPs and ncRNAs holds significant promise for the development of therapeutic strategies aimed at ameliorating RNA-mediated mechanisms in neurodegenerative disorders.",

In addition, increasing evidence indicates that SBMA is a multisystem disorder with prominent non-motor symptoms, such as sensory neuropathy, androgen insensitivity, and glucose intolerance. This study aimed to further characterize the clinical manifestations and biomarker profile in a large Swedish SBMA cohort. 49 genetically confirmed SBMA patients were identified from a motor neuron disease database at Ume\u00e5 University Hospital, Sweden. CAG repeat length in the androgen receptor (AR) gene was assessed by RP-PCR. Blood samples were analyzed for cardiovascular and muscle biomarkers. Clinical data were collected from medical records and interviews, with autopsy findings reviewed in two cases. The mean CAG repeat length was 43.1, with a mean age at motor symptom onset of 58.6\u00a0years. Notably, 19% of patients initially presented with sensory symptoms. High prevalence of hypertonia (70%), diabetes mellitus (39%), and cardiac disease (38%) was observed. Elevated troponin levels were common, and pNfL (neurofilament light chain in plasma) was elevated in seven patients, likely reflecting combined cerebrovascular and cardiovascular comorbidity. Importantly, two of these seven patients exhibited rapid disease progression, and a concomitant diagnosis of ALS was confirmed histopathologically. This cohort was characterized by a relatively low number of AR gene CAG repeats and a late onset of motor symptoms. Sensory symptoms frequently occurred before motor decline. Cardiovascular disease and diabetes were common comorbidities and, in some cases, preceded neurological symptoms. These findings underscore the need for improved clinical awareness of the heterogeneous presentation of SBMA and support routine cardiovascular monitoring to reduce diagnostic delays and prevent early mortality.",
        "41515256": "ID: 41515256\nTitle: Effects of a Red-Ginger-Based Multi-Nutrient Supplement on Optic Nerve Head Blood Flow in Open-Angle Glaucoma.\nAbstract: Objectives: Glaucoma is an age-related neurodegenerative disease, characterized by retinal ganglion cell loss and progressive visual field deterioration. Beyond intraocular pressure (IOP), vascular and metabolic dysregulation contributes to optic nerve head (ONH) ischemia and neuronal vulnerability. Nutritional factors with antioxidative and vasodilatory properties may help preserve ocular perfusion. This study investigated the acute and subacute effects of a single dose of a dietary supplement containing red ginger extract (Zingiber officinale var. rubra), lutein, and vitamin B6 on ONH blood flow in patients with open-angle glaucoma (OAG). Methods: A retrospective self-controlled study was conducted at Tohoku University Hospital between August 2023 and March 2025. ONH blood flow was quantified using a laser speckle flowgraphy (LSFG) baseline one hour after and one month after continuous oral supplementation in patients with OAG. Systemic parameters, ocular biometry, and concomitant glaucoma medications were recorded in medical charts. Relative mean blur rate (MBR) changes were analyzed using a linear mixed-effects model, accounting for repeated measures and inter-eye correlations. Results: Nineteen glaucoma patients (38 eyes) were included in the acute phase and 13 patients (26 eyes) completed the one-month follow-up. After adjusting for age and sex, a single oral dose of red ginger extract significantly increased the relative MBR at 1 h (106.9 \u00b1 3.1%; p < 0.05), and this enhancement increased after 1 month of continuous intake (115.4 \u00b1 6.7%; p < 0.05). Greater ONH perfusion was particularly prominent in eyes with shorter axial length. Conclusions: Oral supplementation was associated with acute and short-term increases in ONH blood flow in glaucomatous eyes. Although this study was a retrospective study without a placebo-controlled comparison group, our findings offer hypothesis-generating evidence that nutritional interventions may support ocular perfusion alongside conventional glaucoma management. Future prospective randomized controlled trials are required to confirm these associations.",

Amyotrophic lateral sclerosis is a degenerative disease of the upper and lower motoneurons with a rapidly progressive course, but non-motor symptoms such as decreased ocular motility and reduced visual acuity have also been reported. Specific biomarkers or surrogate parameters assessing neurodegeneration in ALS are of interest. Methods: In a retrospective, longitudinal study using optic coherence tomography of the retinal layers, we compared changes in the thickness of the layers between patients with ALS and healthy controls. Correlations to clinical scores, such as the modified ranking scale, were analyzed. Results: In our cohort of patients with early ALS (disease duration 5.15 \u00b1 21.4 months at baseline), we neither observed differences in retinal layer thickness at baseline nor did the thickness changes in any retinal layer differ in comparison to healthy controls at baseline. Moreover, we observed no significant thickness changes over the course of the observational period in our patients with ALS. However, a correlation analysis revealed a negative association of the thickness change rates in the complex of ganglion cell and inner plexiform layer and the inner nuclear layer with a higher modified Rankin scale at follow-up. Conclusions: This study adds to the notion that OCT may not be a suitable tool to monitor atrophy and disease progression in ALS. However, further longitudinal studies with longer follow-up times and larger cohorts are warranted.",

In this study, we leveraged data from the All of Us Research Program to assess whether DR serves as an independent marker of neurodegenerative disease among individuals with diabetes. A matched case-control, cross-sectional study was conducted using data from the All of Us Research Program (US-based EHR database). Three groups (exactly matched by age, sex, and race) were created and compared: individuals with both DR and DM (DR+DM, n = 7629), individuals with DM but no DR (DM-only, n = 22,887), and individuals without DM (n = 22,887). Outcomes included dementia, Alzheimer's disease (AD), Parkinson's disease (PD), and multiple sclerosis (MS). Univariate and multivariate logistic regression analyses were performed, adjusting for demographics, comorbidities and diabetes-related mediators. In multivariable analysis, DM-only was associated with increased odds of dementia (adjusted odds ratio [aOR] 1.28, 95 % CI: 1.08-1.51; p = 0.004). However, DR in the setting of DM (DM+DR vs. DM-only) was not associated with further increased odds of neurodegenerative disease outcome in multivariate models (aOR for dementia 1.18, 95 % CI: 0.94-1.49). No significant associations were identified for AD, PD, or MS (all p \u2265 0.10).

However, their shared molecular mechanisms remain poorly characterized. In this study, we performed DIA quantitative proteomic analysis of aqueous humor (AH) from patients with nAMD, PDR, and control. A total of 3186 proteins were identified, in which 877 and 1017 differentially expressed proteins (DEPs) were detected in the nAMD and PDR groups, respectively, compared to control group. Functional enrichment analysis revealed significant involvement of inflammatory and metabolic pathways in both diseases. Notably, the persistent upregulation of cell division cycle 42 (CDC42) and ras homolog family member A (RHOA) in nAMD and PDR, combined with their established role in cytoskeletal remodeling, suggests their significant involvement in pathological angiogenesis. These findings offer novel perspectives on shared pathogenic pathways in neovascular ocular disorders and suggest potential therapeutic targets for further investigation.",

Since the retina is ontogenically brain-derived, we hypothesised that retinal biomarkers could be used, alone or in combination with other simple tests, to screen for MCI in people with diabetes. Baseline data from participants screened for RECOGNISED, a Horizon 2020-funded European project, were analysed. Main eligibility criteria for RECOGNISED included age \u226565 years, type 2 diabetes of over 5 years standing, no previous history of stroke or neurodegenerative disease, and no overt diabetic retinopathy or only mild-to-moderate non-proliferative diabetic retinopathy. Baseline characteristics of participants, including scores from the Montreal Cognitive Assessment test (MoCA) and Self-Administered Gerocognitive Examination, the Diabetes Specific Dementia Risk Score (DSDRS) and ophthalmological endpoints gathered from standardised seven field colour fundus photography, spectral domain optical coherence tomography, microperimetry and a hand-held portable electroretinography device (RETeval), were obtained and used in the work presented here as potential screening predictors for presence of MCI. MCI and normocognition (NC) were determined based on a full neuropsychological test battery and the Clinical Dementia Rating score. A stepwise selection of variables, based on Akaike's information criterion, and logistic regression models for predicting MCI were undertaken. Area under the receiver-operating characteristic curve analyses were used to predict the probability of the presence of MCI as well as sensitivity and specificity cut-off points. A total of 313 people living with diabetes (128 with NC and 185 with MCI) were included. People with diabetes with MCI were older (p=0.006) and had fewer years of education (p<0.001), lower retinal sensitivity (p=0.01) and less capacity of gaze fixation (p\u22640.001) than those with NC. Statistically significant differences in pupillary area ratio (p=0.002) and photopic b-wave amplitude (p=0.03) were detected between people with diabetes with NC and with MCI. Multivariable logistic regression showed that the best model to identify people with diabetes with MCI was that combining retinal sensitivity, gaze fixation, photopic b-wave amplitude and pupillary size change following stimulation, years of education, DSDRS and MoCA score, with an AUC of 0.84 (sensitivity 79.9, specificity 79.0). The visuo-construction domain was the most affected in people with diabetes with MCI and its impairment was independently related to retinal sensitivity and gaze fixation. The assessment of retinal neurodysfunction in combination with simple clinical variables appears useful to identify people with diabetes with MCI. This strategy could optimise current screening of MCI in people living with diabetes.",

The methylxanthine, theophylline acts by multiple mechanisms in different diseases, and we investigated its effect on the development of lesions of early DR. Wild-type C57Bl/6J male mice were made diabetic with streptozotocin at two to three months of age, and some were given theophylline or structurally related analogs for one to two months to assess effects on visual function and biochemical and physiological abnormalities in the retina, or for eight months to assess retinal vascular histopathology. Effects of theophylline on leukocytes were examined ex vivo, because leukocytes contribute to the retinal vascular pathology of diabetes. Retinal superoxide generation, expression of inflammatory proteins, leukocyte-mediated cytotoxicity against retinal endothelial cells, and degeneration of retinal capillaries were significantly increased in retinas of control diabetic mice, and theophylline inhibited each of these abnormalities. Of recognized actions of theophylline (adenosine receptor antagonist, antioxidant and anti-inflammatory agent, inducer of histone deacetylase activity, inhibitor of phosphodiesterases), the inhibition of phosphodiesterases, oxidative stress and inflammation seem most likely to account for the beneficial effects of the drug in DR. In contrast to the beneficial effect of theophylline on capillary degeneration, it did not inhibit the diabetes-induced dysfunction of the neural retina. Theophylline significantly inhibited the degeneration of retinal capillaries in early DR and can help investigate mechanistic differences in the pathogenesis of retinal capillary degeneration and neural dysfunction in diabetes.",

Here, we present a tetrahedral framework DNA-based bioswitchable Tri-miR-22 mimic delivery system (BiRDS), which is specifically engineered for extraocular administration. In vitro, BiRDS can penetrate the cell membrane within 24\u2009h and accumulate extensively in the cytoplasm. Through transscleral-choroidal-retinal penetration, BiRDS achieves robust delivery to the choroid and retina within 18\u2009h without the need for intravitreal injection in mice. The BiRDS can effectively inhibit the proliferation, tube formation and migration abilities of human umbilical vein endothelial cells. In murine models of choroidal neovascularization and oxygen-induced retinopathy, BiRDS not only suppresses retinal pathological neovascularization with efficacy comparable to that of current anti-VEGF agents, but also possesses unique effects that current agents lack, such as improved retinal perfusion and preserved neuronal integrity, thereby contributing to the protection of visual function. Furthermore, transcriptomic profiling and molecular validation revealed that BiRDS exerts its therapeutic efficacy by inhibiting the Wnt/\u03b2-catenin pathway, a key driver of mediating the aforementioned pathological processes. This study highlights BiRDS as a next-generation RNA nanotherapy with broad clinical potential, offering site specific, multitargeted modulation via a minimally invasive and patient-friendly route.",

This study identifies concurrent FDX1-dependent retinal ganglion cell (RGC) cuproptosis and MyD88-mediated microglial inflammation as key drivers of retinal neurodegeneration in RIR. To address this, we developed SAH-CIM, a self-assembled nucleic acid hydrogel for sustained co-delivery of siFdx1 and siMyd88. SAH-CIM effectively suppressed RGC cuproptosis via FDX1 knockdown and reduced pro-inflammatory cytokines by inhibiting the MyD88/TRAF6/NF-\u03baB pathway. In murine RIR models, prophylactic SAH-CIM administration preserved 25.3% more retinal ganglion cells than free siRNA controls, with structural integrity confirmed by histological analysis and optical coherence tomography. Functional recovery was evidenced by electroretinography and visual cliff tests, with SAH-CIM treated mice showing 36.6% reduced time on the cliff side. Crucially, the dual-targeting design demonstrated significantly superior therapeutic efficacy over single-target approaches. The highly biocompatible and self-assembled SAH-CIM presents a promising prophylactic resolution for RIR-related diseases with broad translational potential.",

Early diagnosis remains challenging due to the absence of reliable and validated biomarkers. Calprotectin, a well-established inflammatory marker in various neuroinflammatory conditions, has paradoxically been found at reduced levels in the blood of ALS patients in a limited number of studies, raising the hypothesis of immune dysregulation rather than classical neuroinflammation. However, these findings are primarily derived from small patient cohorts and have yet to be independently replicated. This review critically assesses the emerging role of calprotectin in ALS by comparing it with other candidate biomarkers, including vascular endothelial growth factor (VEGF), apolipoprotein A1 (ApoA1), interleukin-8 (IL-8), interleukin-7 (IL-7), and interleukin-10 (IL-10). While calprotectin may reflect a distinct immunological profile, its standalone diagnostic value remains unclear. Nonetheless, its integration into a multi-analyte biomarker panel could enhance diagnostic precision and biological insight. The review also explores underlying immunological mechanisms, including receptor interactions (RAGE, TLR4, CD33), cellular mediators (microglia, lymphocytes, monocytes), and therapeutic implications. Future research should prioritize mechanistic investigation of calprotectin modulation in ALS, longitudinal validation in larger cohorts, and integration within multimodal biomarker frameworks. A better understanding of disease-specific immune alterations may contribute to earlier diagnosis, stratified patient monitoring, and targeted therapeutic development.",

Traditionally considered as primarily vascular diseases, these conditions are now increasingly recognized to involve early neurodegenerative processes that may precede vascular dysfunction. Although anti-VEGF therapies have revolutionized the treatment of neovascular retinal diseases, long-term VEGF inhibition has been associated with adverse effects, including retinal atrophy and diminished neuroprotection, underscoring the need for more targeted strategies. Recent studies have highlighted the differential roles of VEGF-A splice isoforms, particularly the pro-angiogenic VEGF-Axxxa and the anti-angiogenic VEGF-Axxxb, in maintaining RNVU homeostasis and contributing to disease progression. In parallel, neurotrophins such as nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) have demonstrated the ability to exert neuroprotective, anti-inflammatory, and vasomodulatory effects, partly through modulation of VEGF-A signaling. Notably, we have recently demonstrated that NGF modulates VEGF-A isoform expression and VEGFR-2 levels in diabetic retinas, further supporting the hypothesis of a functional cross-talk between neurotrophins and angiogenic pathways. Based on this evidence, a new model is proposed, in which NGF and BDNF interact bidirectionally with VEGF-A to preserve RNVU integrity. This integrated therapeutic perspective, combining neurotrophic support with selective modulation of VEGF-A isoforms, may enhance treatment efficacy, reduce long-term side effects, and minimize the burden of care in chronic retinal neurodegenerative diseases.",

This condition frequently progresses asymptomatically toward irreversible blindness without timely intervention. The early identification of VTDR is challenging due to the lack of validated biomarkers and a reliance on subjective clinical assessments. This study aimed to develop and validate an interpretable machine learning (ML) model to detect VTDR among patients with diabetic retinopathy (DR). Retrospective clinical data from T2DM patients with DR were extracted from the electronic medical records at our hospital and categorized into VTDR and non-VTDR (defined as mild-to-moderate non-proliferative diabetic retinopathy) groups. The dataset was partitioned into training and testing sets (7:3 ratio). Eight ML models were trained and evaluated using metrics such as Area Under the Curve (AUC), accuracy, and recall. Model performance was evaluated using a comprehensive scoring system (total score = 64). Shapley Additive Explanations (SHAP) were used to interpret the best-performing model. A web-based application was developed to demonstrate potential clinical utility. Among 1,124 enrolled patients, the prevalence of VTDR was 36.9%. Key associated factors included diabetic treatment, T2DM duration, glycated hemoglobin levels, albuminuria, and anemia. The Support Vector Machine (SVM) model demonstrated superior performance, with an AUC of 0.879, accuracy of 0.837, precision of 0.833, Brier score of 0.129, and an F1 score of 0.756, outperforming the other ML models. The SVM model achieved the highest total score (57/64) in the testing cohort. Furthermore, decision curve analysis and calibration curves confirmed the robustness and reliability of the models. A simplified calculator derived from the SHAP feature importance rankings maintained strong diagnostic capacity. The interpretable SVM model effectively detected VTDR among patients with DR using routine clinical data. While requiring external validation, this study serves as a proof-of-concept for a cost-effective screening tool that could assist clinicians in prioritizing high-risk patients and facilitating early intervention to prevent irreversible vision impairment.",

Pericyte loss or dysfunction represents a central pathological feature in diabetic retinopathy (DR) and is increasingly recognized in neurodegenerative diseases as well as in poor stroke outcomes, underscoring an urgent need for therapies that restore pericyte function or promote their regeneration. Here, we utilized a Frizzled4 (FZD4) and Low-Density Lipoprotein Receptor-Related Protein 5 (LRP5) agonist antibody (F4L5.13) to investigate the functional consequences of mimicking \u03b2-catenin-dependent signaling in CNS endothelial cells (ECs), which is physiologically induced by Norrin or WNT7A/B. In platelet-derived growth factor subunit B (Pdgfb) EC-specific knockout (ECKO) mice, a model of severe developmental pericyte deficiency with secondary blood-retina barrier (BRB) defects and hemorrhages, F4L5.13 significantly promoted retinal pericyte/mural cell proliferation and coverage, improved BRB function, reduced hemorrhages, and normalized vascular morphology. F4L5.13 restored Pdgfb mRNA expression levels from non-recombined cells in Pdgfb ECKO retinas. These findings highlight interactions of \u03b2-catenin-dependent signaling and PDGFB production, identify a key pharmacodynamic action of F4L5.13 distinct from anti-VEGF therapies, and suggest that FZD4/LRP5 agonists may have uses as a regenerative pharmacology approach that promotes pericyte coverage in the neurovascular unit.",

Owing to the exceptionally high energetic demands of retinal neurons and supporting cells, even subtle perturbations in mitochondrial redox balance can precipitate progressive retinal dysfunction. Increasing evidence indicates that retinal neurodegenerative diseases, including glaucoma, diabetic retinopathy (DR), age-related macular degeneration (AMD), and inherited optic neuropathies, are characterised not by uniform oxidative stress, but by disease- and stage-specific mtROS signatures shaped by mitochondrial quality control capacity. This review synthesises current insights into the sources, regulation, and signalling functions of mtROS in the retina, with particular emphasis on threshold-dependent redox transitions, reverse electron transport, and the progressive failure of mitochondrial quality control mechanisms, including mitophagy, mitochondrial dynamics, and redox-responsive transcriptional networks. The limitations of non-selective antioxidant strategies are critically examined, highlighting why indiscriminate ROS suppression has yielded limited clinical benefit. In contrast, emerging therapeutic approaches aimed at recalibrating mitochondrial redox homeostasis, rather than abolishing physiological signalling, are discussed in the context of disease stage, metabolic state, and mitochondrial competence. By integrating redox biology with mitochondrial quality control and precision medicine concepts, this review proposes a unifying framework in which retinal neurodegeneration is governed by regulated mtROS signalling and the progressive exhaustion of mitochondrial resilience. This model defines critical therapeutic windows for mitochondria-targeted intervention and provides a framework for biomarker-guided patient stratification.",

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.",

Nevertheless, growing evidence supports a bidirectional interaction between circadian dysfunction and neurodegeneration, leading to the proposal of circadian disruption as a significant contributing factor to neurodegenerative disorders. This study aimed to assess the impact of disrupting lighting conditions on the circadian rhythmicity and the retinal degenerative process in retinitis pigmentosa mice. Homozygous rd10 mice were maintained under a conventional 12:12\u00a0h LD cycle or under an ultradian 3:3\u00a0h LD cycle from P19 to P27. Spontaneous locomotor activity was continuously recorded during this period. At P27, retinal responsiveness was assessed by electroretinography, retinal thickness was measured by OCT, and the oxidative stress of the retina was evaluated. Locomotor activity recordings showed deterioration in the circadian rhythmicity of LD 3:3 mice, with small circadian amplitude, low phase homogeneity and loss of circadian periodicity. Besides, retinal responsiveness decreased in LD 3:3 mice, with significant differences between the two groups for b-wave amplitudes. Mean retinal thickness also decreased in LD 3:3 mice. Finally, LD 3:3 mice showed increased levels of DHE fluorescence at the photoreceptor plane, indicating increased oxidative stress. This study provides evidence that exposure to LD 3:3 cycles induces circadian disruption, enhances oxidative stress in photoreceptors and exacerbates retinal degeneration in retinitis pigmentosa mice.",

However, their roles in glaucoma and optic nerve injury remain largely unexplored. Here, we reported that astrocyte primary cilia elongated after optic nerve injury, and genetic ablation or shortening of these cilia significantly increased retinal ganglion cell (RGC) survival. Furthermore, single-cell transcriptomic analysis identified astrocytes as the predominant cell type transducing Sonic hedgehog (Shh) signaling. Activation of canonical Shh signaling, which is transduced through primary cilium, downregulated the expression of reactive astrocyte markers, including glial fibrillary acidic protein (GFAP) and complement component 3 (C3). Using adeno-associated virus (AAV)-mediated gene delivery, we further demonstrated that activating astrocytic Shh signaling or shortening their primary cilia promoted RGC survival by suppressing astrocyte reactivity. Together, our findings reveal a critical role for primary cilia and cilia-dependent Shh signaling in modulating astrocyte reactivity to promote RGC survival after optic nerve injury.",

However, most studies overlook neurodegenerative cohorts and primarily rely on unimodal approaches, thus failing to leverage advanced deep multimodal fusion techniques to capture modality-specific features and cross-modal interactions. To address the issue, this study aims to design a multi-attention-based deep multimodal network to fuse functional VF with structural CFP and OCT. Using data from 354 eyes with neuropathies (glaucoma, ischaemic optic neuropathy, dementia and Parkinson\u2019s) and 228 normal eyes, we developed novel deep learning techniques for disc segmentation, fovea localisation, disc-fovea angle calculation and alignment, and multi-attention-based deep intermediate multimodal fusion incorporating different combinations of spatial, self- and cross-modal attention mechanisms. The results indicate that our proposed multi-attention-multimodal fusion network (MAM-Fusion-Net) achieved an area under the sensitivity\u2013specificity curve (AUC) of 0.998 (95% CI 0.996\u20131.000) for diagnosing neuropathy versus normal participants and 0.981 (95% CI 0.966\u20130.996) for glaucoma versus non-glaucoma, surpassing state-of-the-art uni- and multi-modal models. This multi-attention-based deep fusion strategy applied to multimodal images shows potential in glaucoma and neurodegenerative disease diagnosis to assist eye care practitioners.",

Given that the retina is an extension of the brain and closely connected to it, retinal layer thickness can serve as a biological marker of neurodegeneration. The aim of this work was to measure retinal nerve fiber layer (RNFL) thickness in patients with epilepsy in comparison to healthy controls, and to study the impact of epilepsy duration and seizure frequency on RNFL thickness in those patients. This case-control study was conducted on 53 patients matched clinical definition of epilepsy established by the International League Against Epilepsy (ILAE) 2017, and 50 healthy controls. Cognitive assessment using Montreal cognitive assessment scale (MOCA), and measurement of RNFL thickness using Spectral domain Optical Coherence Tomography (SD-OCT), were done to all included patients and controls. The peripapillary RNFL thickness (superior, inferior & average) were all significantly reduced in both eyes in epileptic patients compared to healthy controls (p-value <0.05). There was a statistically significant difference between epileptic patients and controls regarding MOCA score. There was no statistically significant impact of seizure control, history of status epilepticus, anti-epileptic drugs, seizure frequency, or disease duration on RNFL thickness. There was a statistically significant reduction of the retinal nerve fiber layer thickness in epileptic patients in comparison to healthy controls. Epileptic patients had significant impairment in cognitive functions in comparison to healthy controls.",

A recent study demonstrates that RPE cells release insulin in response to photoreceptor outer segment (POS) phagocytosis and starvation conditions. However, the downstream signalling pathway of this local insulin production has not yet been identified. Therefore, using the ARPE-19 cell line as an in vitro model of human RPE, we have investigated insulin signalling in basal conditions and after rod OS phagocytosis. Our data show that ARPE-19 cells express key pancreatic \u03b2-cell markers, including the transcription factor Pancreatic and Duodenal Homeobox-1 (PDX-1), which translocates to the nucleus in response to phagocytosis, and prohormone convertase 1/3 (PC1/3). In addition, ARPE-19 cells synthesize and secrete insulin already in basal conditions, increasing their release after phagocytosis. The RPE-secreted insulin acts in an autocrine manner, activating the canonical insulin signalling pathway and leading to increased phosphorylation of insulin receptor (IR), insulin receptor substrate-1 (IRS-1), and AKT. An upregulation of the insulin-responsive glucose transporter GLUT4 and increased glucose uptake was also observed, fueling the ARPE-19 cells' oxidative energy metabolism, incrementing the oxidative phosphorylation activity, probably to sustain the high energy demand associated with phagocytosis. At the same time, a decrease in lactate release has been observed. These features may have important implications for understanding retinal energy metabolism and developing novel therapeutic strategies for retinal neurodegenerative diseases.",

Forty patients with NIID and 40 healthy controls underwent optical coherence tomography to measure peripapillary retinal nerve fiber layer (RNFL) and macular ganglion cell complex (GCC) thickness. Among patients with NIID, 37 underwent structural MRI for quantification of visual-region volumes and 30 underwent resting-state functional MRI for graph-theoretical assessment of visual-network topology. Cognitive function and activities of daily living were evaluated in the NIID cohort. Partial correlation and exploratory mediation analyses were used to examine associations among retinal, neuroimaging, and clinical measures. Patients with NIID showed diffuse thinning of the RNFL and GCC relative to controls, with mean GCC showing the best discrimination between groups. Thinner retinal measures were associated with poorer cognition, worse daily function, and lower mean cortical thickness. Structural MRI identified volume abnormalities in selected visual-system regions, particularly the lateral geniculate nucleus, early visual cortex, and dorsal/parietal regions, and retinal thickness correlated positively with the volumes of several visual regions. Poorer daily function was associated with a lower clustering coefficient of the visual network. Left V3d, the dorsal part of area V3 in the occipital visual cortex, partially mediated the association between retinal thinning and functional impairment. These findings support coordinated retina-brain involvement in NIID across retinal, structural, and network levels, and identify OCT-derived RNFL and GCC thickness as accessible, noninvasive candidate biomarkers of disease severity.",

MGCs are the principal radial glial cells of the vertebrate retina, extending from what is composed of a characteristic funnel-shaped morphology spanning throughout the retinal thickness. Their cell bodies are in the inner nuclear layer (INL), and their processes span from the outer limiting membrane to the inner limiting membrane, where they strongly associate with neurons, blood vessels, and the extracellular matrix across all layers of retinal structure. These cells preserve ionic and water homeostasis, control neurotransmitter uptake, and participate in constructing the blood retinal barrier (BRB), as well as deliver crucial metabolic help to neurons by means of the glutamate-glutamine cycle, thus excluding excitotoxic injury. First, we analysed the molecular processes underlying MGCs activation: pro-inflammatory molecules, Reactive oxygen species (ROS), and survival pathways. Special notice was made of changes in gene expression upon activation and the recrudescence of embryonic developmental programs that permit cell-cycle re-entry and retinal regeneration. Systematic searches of Google Scholar and PubMed to find relevant literature. Upon activation, M\u00fcller's glia, a type of retinal support cell, commence the expression of protective genes, such as Zfp36, Mt1, and Slc14a1. Some creatures could regenerate; however, in mammals, this capacity is limited, which is particularly evident in the retina, where, despite the activation of M\u00fcller's glia, full regeneration of damaged photoreceptors is not achieved. MGCs produces retinal progenitors that assist photoreceptors and interneurons while maintaining retinal integrity. MGCs contain progenitor cells that can differentiate into both neurons and other retinal cell types. Molecular targets for retinal therapeutics that utilize MGCs include pathways that regulate inflammation and oxidative stress. M\u00fcller glial cells are essential for maintaining retinal health, safeguarding neurons, and facilitating their regeneration. Targeted molecular therapy is addressed as a promising strategy for retinal neurodegenerative diseases, using their regenerative and protective potential.",

This retrospective cohort study included 780 cataract patients categorized into 3 groups: DR DM (n\u2005=\u2005117, with DR per ETDRS criteria), non-DR DM (n\u2005=\u2005328, T2DM without DR), and non-DM controls (n\u2005=\u2005335). Matching was done via propensity score (age, sex, diabetes duration). Data on diabetes characteristics, systemic comorbidities, and surgical outcomes were extracted. Inflammation was assessed by anterior chamber reaction (SUN criteria) and tear cytokines (monocyte chemoattractant protein-1 [MCP-1], interleukin-6 [IL-6]) measured pre- and postoperatively. Outcomes included postoperative complications and visual recovery (logarithm of the minimum angle of resolution [\u0394logMAR]). Analyses used logistic regression, ANOVA, and chi-square tests. The DR DM group exhibited the highest rates of acute anterior chamber inflammation (15.4%), significantly elevated in proliferative diabetic retinopathy (PDR) patients (18.3%, P\u2005<\u2005.01). Tear MCP-1 and IL-6 levels peaked at 1 week post-surgery, with PDR patients showing markedly higher concentrations (MCP-1: 1023.6\u2005\u00b1\u2005124.8 pg/mL vs non-proliferative diabetic retinopathy: 835.4\u2005\u00b1\u2005112.5 pg/mL; IL-6: 52.5\u2005\u00b1\u200512.9 pg/mL vs 43.7\u2005\u00b1\u200511.4 pg/mL; P\u2005<\u2005.001). Visual recovery (\u0394logMAR) was significantly less in PDR patients (0.27\u2005\u00b1\u20050.25) compared to non-DR DM (0.12\u2005\u00b1\u20050.16, P\u2005<\u2005.001). Complication rates were highest in DR DM patients (25.7%), particularly macular edema (18.2%) and DR progression (9.3%). HbA1c\u2005>\u20059% and diabetes duration\u2005>\u200510 years were independently associated with poor visual recovery (odds ratio\u2005=\u20052.0, P\u2005<\u2005.001) and elevated macular edema risk (odds ratio\u2005=\u20052.3, P\u2005<\u2005.001). DM-related factors, especially PDR and poor glycemic control, significantly influence acute postoperative inflammation, short-term visual recovery, and complication risks within the 3-month follow-up period. However, this duration is insufficient to evaluate long-term outcomes such as posterior capsular opacification or persistent macular edema. These findings underscore the need for optimized preoperative glycemic management and targeted postoperative care to improve early outcomes in DM patients undergoing cataract surgery. Future research with extended follow-up should focus on inflammation-targeted interventions and long-term prognosis.",

This review examines the pathogenic mechanisms shared across glaucoma, age-related macular degeneration (AMD), diabetic retinopathy (DR), and Alzheimer's disease (AD), and evaluates the therapeutic rationale for targeting both pathways simultaneously. A narrative review of peer-reviewed literature was conducted using PubMed. Searches combined the following MeSH terms: neuroinflammation, oxidative stress, retinal neurodegeneration, microglia, M\u00fcller glia, mitochondrial dysfunction, glaucoma, age-related macular degeneration, diabetic retinopathy, and Alzheimer's disease. Priority was given to original research, systematic reviews, and high-impact publications from 2000 through 2025. However, seminal foundational works were included regardless of publication date. Studies were selected based on relevance to glial activation, mitochondrial dysfunction, reactive oxygen and nitrogen species, and disease-specific neuronal outcomes. Across all four diseases, persistent microglial and M\u00fcller glial activation, mitochondrial electron transport chain dysfunction, and excess reactive oxygen species (ROS) and reactive nitrogen species (RNS) production form a self-amplifying feed-forward loop that accelerates neuronal injury. In glaucoma, these mechanisms drive intraocular pressure-independent retinal ganglion cell loss. In AMD and DR, lipid dysregulation, complement activation, and chronic hyperglycemia sustain oxidative-inflammatory injury to the retinal pigment epithelium, photoreceptors, and neurovasculature. In AD, retinal amyloid deposition and oxidative stress mirror cortical pathology, positioning the retina as a noninvasive biomarker site. Neuroinflammation and oxidative stress constitute unifying upstream mechanisms across major vision-threatening neurodegenerative diseases. Combination therapeutic strategies that simultaneously modulate glial activation and restore redox homeostasis may offer superior neuroprotective efficacy compared to approaches targeting isolated downstream mediators.",

This study investigated alterations in double-stranded DNA (dsDNA) levels in the aqueous humor and retinal pigment epithelium (RPE) dysfunction in DR patients, exploring the potential role of the cyclic GMP-AMP synthase (cGAS)-STING pathway in DR progression. We found that DR patients showed significantly elevated dsDNA levels in the aqueous humor compared with control individuals. Fundus autofluorescence imaging revealed an increase in high-autofluorescence spots in DR patients, indicating early RPE dysfunction. In vivo and in\u00a0vitro models of DR demonstrated mitochondrial damage and dsDNA leakage in RPE cells, along with cGAS-STING pathway activation in the retina. Pharmacological inhibition of STING reduced cytoplasmic dsDNA accumulation and damaged mitochondria, alleviating inflammation in\u00a0vitro. In vivo, STING inhibition ameliorated RPE dysfunction and vascular changes. These findings highlight the critical role of the cGAS-STING pathway in DR pathogenesis and suggest that STING inhibition may serve as a promising therapeutic strategy to reduce retinal inflammation and slow the progression of DR. The retinal pigment epithelium (RPE) serves as the outer blood-retinal barrier, protecting the neural retina from systemic changes. We aimed to preserve RPE integrity through early intervention and inhibit DR progression. Our study focused on determining whether the involvement of the cyclic GMP-AMP synthase-STING pathway and mitochondrial damage drive RPE dysfunction. We found that mitochondrial dysfunction in the RPE under diabetic conditions triggers activation of the cyclic GMP-AMP synthase-STING pathway, leading to disruption of RPE and retinal vascular instability. Targeting this pathway restored RPE function and limited retinal deterioration. These findings highlight a promising therapeutic approach for preventing disease progression.",

The transcription factor nuclear factor erythroid 2-related factor 2 (NRF2) plays pivotal roles in the cellular defense system against oxidative and xenobiotic stress, making NRF2 activation a promising therapeutic target for ocular neurodegenerative disorders. Covalent NRF2 activators have been extensively studied in clinical trials, leading to the approval of two drugs. However, no non-covalent NRF2- Kelch-like ECH-associated protein 1 (KEAP1) protein-protein interaction (PPI) inhibitors are currently in clinical development, despite their potential for selective and reversible KEAP1 inhibition with fewer side effects. In this study, to develop high potency compounds with suitable properties for an eye drop preparation, we modified the structure of known NRF2-KEAP1 PPI inhibitors. The newly identified compound, SLOS-1811-06 tR1, exhibited neuroprotective effects at concentrations \u22650.01\u202fnM in a hypoxia-induced neurodegeneration model using human-induced pluripotent stem cell (hiPSC)-derived RGCs. It showed high aqueous solubility (21.04\u202f\u00b1\u202f0.08\u202fmg/mL), enabling easy formulation as an eye drop. One hour after a single topical dose of a 0.5% SLOS-1811-06 tR1 solution in rabbits, its concentration in the posterior retina/choroid was 4.4\u202f\u00b1\u202f2.7\u202fnM, exceeding the effective level observed in vitro. These findings highlight the potential of SLOS-1811-06 tR1 as a promising topical drug candidate for treating oxidative stress-related glaucoma.",

Recent studies have shown multiple beneficial effects of GLP-1 and GLP-1RAs, including anti-inflammatory, antioxidant, and neuroprotective effects, indicating their potential therapeutic applications in treating neurodegenerative diseases. Notably, several ocular disorders, including diabetic retinopathy, glaucoma, age-related macular degeneration, and dry eye disease, also exhibit neurodegeneration-related pathophysiological changes. Hence, it is critical to explore new therapeutic strategies to address the clinical challenges posed by these neurodegenerative ocular diseases. Given this background, we conducted a review of recent preclinical and clinical studies to update and summarize (1) the therapeutic potential of GLP-1/GLP-1RAs for neurodegenerative ocular diseases, (2) clinical evidence supporting the neuroprotective effects of GLP-1/GLP-1RAs in these ocular diseases, and (3) the molecular mechanisms underlying the neuroprotective effects of GLP-1/GLP-1RAs on ocular neural cells, including inflammatory and oxidative stress response inhibition and Ca2+ homeostasis regulation. This review aims to provide a theoretical foundation and research outlook for extending the application of GLP-1RAs to treat neurodegenerative ocular diseases.",

Growing evidence suggests that dysbiosis may also influence ocular immune privilege and blood-retinal barrier stability, supporting the emerging concept of the gut-eye axis. This narrative review aimed to integrate retinal, uveal, and ocular surface disorders within a shared functional framework, with emphasis on recurring mechanistic pathways and their translational relevance rather than on single diseases or isolated taxonomic findings. The review was based on a literature search of PubMed and Scopus and primarily included English-language studies published between 2015 and 2025, with earlier seminal papers included when needed. The search was last updated in March 2026, and 101 sources were included in the final narrative synthesis. Across age-related macular degeneration, diabetic retinopathy, glaucoma, uveitis, dry eye disease, and Sj\u00f6gren's syndrome, the most consistent microbiome-related signals were functional rather than taxonomic. Recurrent mechanistic themes included Th17/Treg immune programming, barrier dysfunction with microbial product translocation, and systemic metabolite signaling, particularly involving short-chain fatty acids, bile acid receptor pathways, and tryptophan-derived metabolites. Age-related macular degeneration and diabetic retinopathy showed the strongest multi-layered support, whereas uveitis provided a compelling immune-centered biological model that remains limited by treatment-related confounding in human studies. In glaucoma and ocular surface disease, evidence supports biological plausibility, especially in relation to neuroinflammation, mucosal immune dysregulation, and metabolite-dependent anti-inflammatory pathways, although much of the available human literature remains associative. Overall, current evidence supports dysbiosis as a disease modifier that may influence ocular inflammation, angiogenesis, neurodegeneration, and barrier stability. However, clinical translation remains limited by cohort heterogeneity, methodological variability, and incomplete control of confounding factors. Further progress will depend on longitudinal multi-omics cohorts and controlled intervention trials focused on actionable microbial functions.",

Due to the growing evidence regarding the key role of neurodegeneration in the earliest stages of the disease and the underlying pathophysiological mechanisms, the relevance of evaluating the potential efficacy of neuroprotective therapies is emphasized. More specifically, the review addresses the current state of a promising neuroprotective approach based on the inhibition of the enzyme dipeptidyl peptidase-4 (DPP-4) using specific inhibitors administered via eyedrops, which allow direct retinal action on the neurovascular unit. The review discusses the main preclinical findings of a therapeutic strategy based on one DPP-4 inhibitor, sitagliptin, against early DRD in different experimental animal models and in vitro studies. In summary, sitagliptin eyedrops exhibit neuroprotective, anti-inflammatory, and antioxidant properties while reducing glial activation, hyperpermeability of the blood-retinal barrier, and the formation of acellular capillaries, leading to a functional improvement of the diabetic retina. However, as sitagliptin efficacy has only been evaluated at the preclinical level, clinical studies are needed to validate the translational applicability and long-term efficacy of topical administration not only of sitagliptin but also of other DPP-4 inhibitors for treating retinal diseases in which neurodegeneration plays a pathogenic role.",
        "42207959": "ID: 42207959\nTitle: RBP4 Aggravates Diabetic Retinopathy by Inducing Microglial Activation and Endothelial Inflammation.\nAbstract: Diabetic retinopathy (DR) is recognized as an inflammatory neurovascular complication, with neuronal deficits preceding vascular symptoms. This study identified elevated serum retinol-binding protein 4 (RBP4) as a risk factor for DR, because it induces retinal neuronal injuries and exacerbates vascular defects. Vitreous RBP4 levels were significantly elevated in patients with DR compared with those with macular disease. Elevated vitreous and serum RBP4 levels exacerbated hyperglycemia-induced endothelial inflammation, retinal vascular leakage, pericyte loss, and acellular capillaries in streptozotocin-induced diabetic mice. Progressive retinal degeneration and impaired electroretinography function were exhibited with RBP4 overexpression, likely through inducing retinal microglial activation and phagocytosis. Microglial depletion via PLX3397 (CSF-1R inhibitor) or inhibition using minocycline (anti-inflammatory tetracycline) significantly mitigated retinal degeneration in RBP4 transgenic (RBP4-Tg) mice. Furthermore, minocycline abolished the enhanced phagocytosis of zymosan in murine microglial BV2 cells induced by RBP4. The application of TAK242 or use of microglia-specific TLR4 knockout markedly reduced retinal neuroinflammation and degeneration in RBP4-Tg mice. Overall, these results suggest that elevated serum and vitreous RBP4 levels may be a risk factor for DR by exacerbating retinal neuronal and vascular injuries. Retinol-binding protein 4 (RBP4) levels are elevated in the vitreous humor of patients with diabetic retinopathy (DR) and in RBP4 transgenic mice. Elevated vitreous RBP4 exacerbates both vascular and neuronal deficits associated with DR in streptozotocin-induced diabetic mice. Hyperglycemia augments the RBP4-induced inflammatory response in retinal microvascular endothelial cells to exacerbate DR-related vascular pathologies. RBP4 triggers retinal microglial activation and phagocytosis via TLR4/nuclear factor-\u03baB/mitogen-activated protein kinase pathway, and microglial depletion or inhibition alleviates RBP4-induced retinal neurodegeneration.",

Retinal neurodegeneration precedes vascular pathology, highlighting the need to identify early molecular biomarkers as a target for intervention. The thrombin receptor, protease-activated receptor-1 (PAR1), a G-protein-coupled receptor involved in coagulation and neuroinflammatory signaling, is expressed in the retina and has been implicated in retinal barrier dysfunction and angiogenesis in late DR. We presently addressed its role in early diabetic neuroretinal pathology. We investigated the thrombin/PAR1 pathway one month after induction of diabetes with streptozotocin (STZ) in mice. Retinal thrombin activity and coagulation-related gene expression were quantified, PAR1 localization was examined by immunofluorescence and cytosolic/nuclear fractionated Western blotting, and retinal function was assessed by electroretinography (ERG). Additionally, we assessed the therapeutic potential of PARIN5, a selective thrombin-PAR1 modulator, across these outcome measures. Diabetic retinas showed increased thrombin activity (2.496 vs. 1.00\u00a0mU/ml, p\u2009=\u20090.01) and PAR1 mRNA expression (1.31\u2009\u00b1\u20090.11 vs. 1.00\u2009\u00b1\u20090.08, p\u2009=\u20090.028), along with decreased prothrombin and factor X mRNA (0.64\u2009\u00b1\u20090.07 vs. 1.00\u2009\u00b1\u20090.05, p\u2009=\u20090.0025; 0.75\u2009\u00b1\u20090.03 vs. 1.00\u2009\u00b1\u20090.09, p\u2009=\u20090.042; respectively). Immunofluorescence confirmed increased PAR1 staining, including nuclear localization, confirmed by fractionated Western blotting. PARIN5 treatment reduced thrombin activity (p\u2009=\u20090.0091), attenuated PAR1 staining, and preserved both dark-adapted (ratio post treatment/pre-diabetes induction: maximal a-wave 1.23\u2009\u00b1\u20090.13 vs. 0.39\u2009\u00b1\u20090.07 for carrier-treated mice, p\u2009=\u20090.0002; maximal b-wave 1.15\u2009\u00b1\u20090.14 vs. 0.49\u2009\u00b1\u20090.08, p\u2009=\u20090.0083) and light-adapted (maximal b-wave 1.21\u2009\u00b1\u20090.14 vs. 0.51\u2009\u00b1\u20090.05, p\u2009=\u20090.0024) ERG responses. Importantly, these molecular and functional changes occurred without morphological alterations in the retina. In conclusion, we identify thrombin/PAR1 increase and nuclear translocation as a novel early event in diabetic retinopathy and demonstrate that PARIN5 treatment preserves retinal function before structural pathology emerges. Modulation of thrombin/PAR1 signaling may provide a new therapeutic strategy for halting or delaying the progression of DR.",
        "42216554": "ID: 42216554\nTitle: NF-\u03baB Involvement in Glaucoma-Associated Neuroinflammation: Focus on Glial Cells.\nAbstract: Glaucoma is a complex neurodegenerative disease characterized by the progressive loss of retinal ganglion cells (RGCs) and optic nerve damage. Both mechanical and vascular factors are believed to contribute to the etiology of glaucoma. However, the underlying pathogenic mechanisms are not yet fully understood. In this article, although it is a single component of a multifactorial condition, we argue that neuroinflammation is a significant factor in glaucoma pathogenesis. Glaucoma, at present, is recognized as a neurodegenerative disorder sharing common neuroinflammatory mechanisms with classical neurodegenerative diseases. The involvement of classical immune signaling pathways, such as TLRs and NF-\u03baB, as well as proinflammatory cytokines like TNF-\u03b1, aligns glaucoma with other neurodegenerative diseases where inflammation is pivotal (e.g., Parkinson's and Alzheimer's diseases). As such, glaucoma should be considered not only an ocular pressure disorder but also a neurodegenerative condition with a strong immune component. This perspective opens new avenues for novel therapeutic intervention, including the targeting of glial cells or modulators of inflammatory signaling. However, the complexity of microglial phenotypes and the timing of their activation relative to astrocytes remain areas that require further clarification. The current M1/M2 paradigm is acknowledged as overly simplistic, highlighting the need for more refined and nuanced models. Although oxidative stress and other interconnected signaling, such as STAT3, are involved in the pathogenesis of glaucoma, here, we focus on the role of the NF-\u03baB signaling pathway within the glaucomatous condition with a special focus on the main characters fostering the neuroinflammation.",

While anti-vascular endothelial growth factor (anti-VEGF) therapy, corticosteroids, laser photocoagulation, and vitreoretinal surgery have improved outcomes, none can permanently prevent disease progression. The complex pathophysiology of DR, which includes inflammation, oxidative stress, and neurodegeneration, highlights the need for additional systemic strategies. This narrative review was informed by a structured search of PubMed, Scopus, and Web of Science covering the period from January 2000 to September 10, 2025. Original studies, systematic reviews, and meta-analyses were included, whereas case reports and editorials were excluded. Findings were synthesized qualitatively. Preclinical models suggest that sodium-glucose cotransporter 2 (SGLT2) inhibitors exert neuroprotective, anti-inflammatory, and antioxidant effects on the retina, preserve the blood-retinal barrier, and reduce vascular endothelial growth factor (VEGF) expression. However, whether these retinal effects are only partially independent of glycemic control remains speculative, as clinical studies have not adequately controlled for changes in glycated hemoglobin (HbA1c) or for differences in concomitant glucose-lowering therapies. Observational clinical studies have associated SGLT2 inhibitor use with a lower risk of DR progression, a reduced incidence of proliferative DR, and fewer vision-threatening interventions compared with some other antihyperglycemic agents. Owing to the established indications in heart failure and chronic kidney disease associated with SGLT2 inhibitors, these agents appear promising for DR prevention and risk modification. However, current clinical evidence is based mainly on observational and retrospective studies and remains vulnerable to confounding and selection bias. Prospective randomized studies with ophthalmic endpoints are needed before firm conclusions can be drawn.",

Although many existing reviews focus on the link between BBB disruption and neuronal degeneration in the brain, a similar analysis of the BRB integrity in retinal degeneration is currently unavailable. Like the BBB, the inner BRB is established by retinal blood vessels encapsulated in a neurovascular unit. The retinal neurovascular unit and BRB are affected not only in retina-specific neurodegenerative diseases (eg, diabetic retinopathy and retinitis pigmentosa) but also in neurodegenerative diseases that primarily affect the brain (eg, Alzheimer disease and Parkinson disease). In this review, the link between vascular abnormalities (including BRB disruption) and retinal neurodegeneration in these diseases will be discussed to highlight the pivotal role of BRB integrity in neuronal homeostasis and health.",

This chapter elucidates their utility in detecting biomarkers for the diagnosis and monitoring of progression and response to treatment in different prevalent neurologic conditions. The retina, an extension of the central nervous system, presents a unique opportunity for monitoring brain pathology due to its accessibility. Through highly resolved scans of the retina and optic nerve, OCT and OCTA facilitate the identification of subtle clinical changes occurring during neuroinflammatory, neurodegenerative, and ischemic processes in disorders like multiple sclerosis, Alzheimer and Parkinson disease, anterior ischemic optic neuropathies, and papilledema. Peripapillary nerve fiber layer and macular internal retinal layer thickness on OCT, and vessel density in the superficial retina on OCTA seem to be the most sensitive parameters in detecting axonal injury and neurodegeneration. These metrics hold promise as surrogate markers for cerebral alterations. While OCT and OCTA show considerable potential, continued research is necessary to validate their reliability and clinical significance, considering potential confounding factors such as concurrent ophthalmic pathologies. Nonetheless, these advancements represent significant progress toward enhancing the diagnosis, management, and prediction of outcomes in various neuro-ophthalmic disorders.",
        "42217982": "ID: 42217982\nTitle: Insights into retinal remodeling in retinal degenerative disease.\nAbstract: The retina is a highly organized sensory structure responsible for capturing and processing visual information. Visual computation begins at the first synapse between photoreceptors, bipolar cells, and horizontal cells, before involving amacrine and ganglion cells to generate vision. Retinal degeneration disrupts the precise neural architecture required for vision, initiating a maladaptive process known as retinal remodeling. Photoreceptor degeneration in diseases, like retinitis pigmentosa (RP) and age-related macular degeneration, induces retinal remodeling, but good evidence shows glaucoma and diabetic retinopathy do as well, expanding the clinical significance. Historically, studies relied on histologic measures that assumed photoreceptor degeneration marked disease endpoints. However, retinal remodeling involves extensive structural and functional reorganization across all retinal cell classes, driven by the interdependence between neurons, glia, and the retinal pigment epithelium. Retinal plasticity corrupts normal retinal computations, and recent evidence suggests therapeutic windows close after \u223c50% photoreceptor loss. Understanding remodeling mechanisms is critical for effective therapies, as current treatments fail to address the ongoing negative plasticity. Insights from retinal remodeling offer broader implications for neurodegeneration, highlighting the retina as a model for understanding central nervous system diseases like Alzheimer and Parkinson.

We aimed to identify circulating plasma protein signatures of diabetic retinal neurodegeneration (DRN) and to translate them into a clinically usable risk prediction system. In this multi-cohort prospective observational study, we integrated high-throughput plasma proteomics with longitudinal optical coherence tomography (OCT) in two independent populations. The discovery cohort comprised 1,492 participants had baseline plasma proteomics and OCT, and 1,218 were followed with repeated OCT over 6 years in Guangzhou Diabetic Eye Study (GDES). DRN was quantified by the annualized OCT-derived retinal nerve fiber layer thinning rate. In multivariable analyses adjusted for age, sex, smoking, systolic blood pressure, HbA1c, and diabetes duration, we identified 71 plasma proteins associated with development and progression of DRN. These proteins mapped onto pathways governing inflammatory immune recruitment, extracellular matrix remodeling, and microvascular homeostasis, providing a plausible biological basis for DRN. We developed a proteomics-based DRN model (Pro-DRN) using eight machine learning (ML) algorithms, including XGBoost and LightGBM. In the independent test set, Pro-DRN achieved a C-index of 0.860, rising to 0.908 when integrated with clinical variables. Compared with six conventional models, Pro-DRN improved discrimination (\u0394C-index 0.137 to 0.159; all P\u2009<\u20090.001), reclassification (IDI 0.212 to 0.245; NRI 0.226 to 0.452; all P\u2009<\u20090.05). In the Hippisley model, the C-index increased from 0.739 (95% CI [0.670, 0.808]) to 0.898 (95% CI [0.858, 0.937]), with IDI 0.245 (95% CI [0.177, 0.318]), NRI 0.452 (95% CI [0.222, 0.673]) (both P\u2009<\u20090.001), and higher net benefit. The proteins most consistently driving model performance included ACTA2, COL6A3, and HSPG2. For clinical translation, we deployed the locked model as an interactive, web-based risk-assessment tool to support early DRN screening and longitudinal monitoring. Cross-ethnic external validation in UK Biobank (n\u2009=\u2009502; recruited 2006-2010) reproduced core protein signals and consistent effect directions, confirming robustness across populations. Principal methodological limitation lies in single time point proteomic assessment. In this multi-cohort study, we present a proteomics- and ML-based precision prediction system for DRN. Pro-DRN substantially enhanced early risk stratification beyond conventional clinical factors and may support targeted screening and timely neuroprotective interventions, advancing molecularly guided strategies for diabetic eye disease prevention.",

However, the role of IDE in PD pathogenesis remains insufficiently defined. This study aimed to investigate the association of IDE gene polymorphisms and serum IDE levels with sporadic PD in a Chinese Han population. Fourteen single nucleotide polymorphisms (SNPs) within the IDE gene were genotyped in 463 patients with sporadic PD and 576 age- and sex-matched healthy controls (HCs). An independent cohort of 100 PD patients and 100 HCs was used to quantify serum IDE concentrations. Correlations between IDE levels and clinical features were assessed. Logistic regression was employed to identify independent factors associated with PD. Among the examined SNPs, rs11187007 showed a nominal allelic association with PD (P = 0.046), which did not survive the Bonferroni correction. Serum IDE concentrations were significantly higher in PD patients than in HCs (P = 0.015). Elevated IDE levels were negatively correlated with Mini-Mental State Examination scores (R = -0.230, P = 0.027) and positively associated with more severe symptoms. Logistic regression indicated that elevated serum IDE levels were associated with PD. Our findings highlight that elevated serum IDE correlates with PD, suggesting a role for IDE in neurodegeneration, warranting further mechanistic and longitudinal studies to evaluate its potential as a therapeutic target in PD.",

This study aimed to assess the neuroprotective effects of novel curcumin-indole-3-propionic acid conjugate (CUR-IPA) against high glucose (HG)-induced damage in SH-SY5Y neuronal cells. Cells were exposed to HG to simulate diabetic stress and co-treated with CUR-IPA (6.25-25 \u00b5M). Cell viability, oxidative stress markers, mitochondrial membrane potential (MMP), and apoptosis were evaluated. Flow cytometry was used to quantify the expression of apoptotic (p53, Bax, caspase-3, and Bcl-2), survival (p-Akt and mTOR), and neurotrophic (BDNF, p-TrkB, and CREB) proteins. HG induced oxidative stress, loss of MMP, apoptosis, and suppression of PI3K/Akt/mTOR and BDNF/TrkB/CREB pathways. In conclusion, CUR-IPA demonstrates strong neuroprotective potential under HG stress by modulating redox status, mitochondrial function, and survival signaling. The findings suggest its promise as a multi-target therapy for diabetes-linked neurodegeneration, and warrant an in vivo study. Not applicable.",
        "42239431": "ID: 42239431\nTitle: Mesenchymal-derived neural progenitors underlie local insulin production and neuronal transdifferentiation during retina regeneration.\nAbstract: In humans, retinal-neuron death, optic-nerve injuries, and associated neurodegenerative diseases, such as glaucoma and age-related macular degeneration, often lead to permanent vision loss. While the capacity for regeneration is low in the human nervous system, including the retina, some non-mammalian vertebrate species, including zebrafish, are capable of endogenous neuronal regeneration after injury. Unlike mammals, zebrafish do not form a scar that inhibits axonal and neuronal regeneration after injury. Rather, they harbor neural progenitor and stem-cell populations allowing regeneration of entire parts of the nervous system and restoration of tissue integrity and function. In the zebrafish retina, cycling neural progenitor cells of the ciliary marginal zone and quiescent resident neural stem cells (the latter of which are also called M\u00fcller glial cells) participate in neuronal regeneration following different types of injury. In this study, we report the identification of a novel, additional cellular source participating in neuronal regeneration of neurons in the zebrafish retina after genetic ablation of retinal ganglion cells. Before injury, these progenitor cells express molecular markers of neural-crest-cell and/or fibroblast identity, such as sox10, pdgfrb, and eya2, while after neuronal ablation they also express proneural factors including the ascl1a and olig2 genes. Combining genetic ablation of neurons with photoconversion or Cre/Lox-dependent genetic lineage tracing of sox10-expressing cells, we demonstrated that these cells can differentiate into post-mitotic retinal neurons in the ganglion cell layer (GCL) in the absence of cell proliferation. We also showed, surprisingly, that this progenitor population locally produces insulin mRNA, and that insulin signaling is involved in the accumulation of mesenchymal-derived neural progenitors in the GCL and in their subsequent transdifferentiation into RGCs. This work reveals an unexpected and novel cellular mechanism of transdifferentiation, dependent on a neural-crest-derived mesenchymal cell population, participating in neuronal regeneration in the zebrafish retina. The discovery of this plastic cell population could potentially lead to new strategies to promote the formation of new neurons in the mammalian retina.",

Current conventional management provides limited symptomatic relief, highlighting the need for complementary approaches. In Ayurveda, this condition can be considered an Upadrava (complication) of Prameha (diabetes mellitus) and is managed through a combination of internal medications, external therapies, and detoxification procedures.

Clinical assessment using the visual analog scale (VAS), Neuropathy Disability Score (NDS), and neuropathy grading showed significant improvement following the intervention. The patient, who initially presented with moderate neuropathy, showed marked clinical improvement after 2\u202fmonths of treatment. This case suggests that Ayurvedic interventions may offer a beneficial complementary approach in the management of diabetic peripheral neuropathy.

Diosgenin, a natural steroidal sapogenin with potent anti-inflammatory properties, has shown therapeutic potential for ocular and neurodegenerative diseases but has not been explored for retinal degeneration. This study examined the protective role of diosgenin against PRC degeneration and explored potential anti-inflammatory mechanisms in an N-methyl-N-nitrosourea (MNU)-induced mouse model of retinal degeneration. The model was established by intraperitoneal injection of 50 mg/kg MNU, followed by oral gavage of diosgenin/lutein (positive control)/vehicle. The effects of diosgenin on PRC structure, apoptosis, retinal function, and glial activation were evaluated. Network pharmacology and molecular docking were used to investigate potential mechanisms. Diosgenin preserved retinal integrity and function in MNU-induced mice, with relative preservation of the outer nuclear layer thickness and outer segment (OS) length of rods and cones. Disorganization of OS membrane discs and abnormal morphology of organelles were attenuated, while fundus photographs showed fewer lesions. Furthermore, diosgenin mitigated PRC apoptosis and maintained retinal light responses. Mechanistically, diosgenin ameliorated reactive gliosis of M\u00fcller glial cells (MGCs), attenuated the expression levels of inflammatory cytokines and chemokines, and mitigated activation of the IL6ST/JAK2/STAT3 pathway. Diosgenin attenuated PRC degeneration in MNU-induced mice, and one of its mechanisms may involve the attenuation of reactive gliosis in MGCs and inflammatory responses, with possible involvement of the IL6ST/JAK2/STAT3 pathway. Diosgenin may serve as a potential intervention candidate for retinal degenerative diseases, such as RP.",

Dysglycemia, encompassing diabetes mellitus and impaired glucose regulation, is increasingly recognized as a modifiable risk factor for cognitive decline, particularly VCI. Chronic low-grade inflammation mediates the association between metabolic dysfunction and neurodegeneration. The lack of validated diagnostic tools for early VCI detection in high-risk dysglycemic populations highlights the urgent need for robust diagnostic models based on molecular signatures. We analyzed serum samples from 94 participants, categorized into three groups: normal glucose with normal cognition (NG-NC), dysglycemia with normal cognition (Dys-NC), and dysglycemia with VCI (Dys-VCI). Using the Olink Target 96 Inflammation Panel, we quantified 92 inflammation-related proteins. Differentially expressed proteins (DEPs) were identified as potential biomarkers, followed by functional enrichment analysis to explore associated biological pathways. Logistic regression models, combined with ROC analysis, assessed the diagnostic utility of selected protein panels across groups. Compared with NG-NC, the Dys-NC group exhibited upregulated pro-inflammatory mediators (CXCL1, CXCL5, OSM) and downregulated anti-inflammatory proteins (FGF-21, AXIN1). The Dys-VCI group showed significant increases in TNFB, IL-12B, TNF, and CSF-1. Key proteins, including AXIN1 and CX3CL1, displayed progressive changes across the metabolic-cognitive spectrum. Pathway analysis revealed enrichment in cytokine-cytokine receptor interaction, viral protein interaction with cytokine and cytokine receptor, TNF signaling, and chemokine signaling pathways. A four-protein panel (CCL3, CX3CL1, FGF-21, CXCL1) achieved an area under the curve (AUC) of 0.903 for distinguishing Dys-NC from NG-NC, while another panel (TNFB, IL10, IL-12B, CX3CL1) demonstrated an AUC of 0.799 for identifying Dys-VCI among Dys-NC. Our study identified unique inflammatory protein profiles associated with different metabolic and cognitive states, providing insights into inflammatory mechanisms linking dysglycemia and VCI, and highlighting potential biomarker candidates for longitudinal validation.",

It is caused primarily by pathogenic variants in the WFS1 gene, which encodes a transmembrane endoplasmic reticulum-resident protein involved in the unfolded protein response and cellular calcium homeostasis. Although multiple rodent models of Wolfram syndrome have been developed and shown to exhibit visual defects, some studies have reported significant vision loss prior to any detectable axonal degeneration or myelin abnormalities, and the mechanisms underlying these early visual deficits remain poorly understood. Recent in vitro studies have demonstrated altered synaptic contacts and aberrant neurite morphology in WFS1-deficient cerebral organoids and human iPSC-derived neurons, respectively. These findings prompted us to investigate, for the first time in vivo, whether synaptic and dendritic abnormalities occur in the retina of Wfs1 knockout mice. Using confocal microscopy, we examined retinal and optic nerve histology in Wfs1 knockout mice at 4 and 7 months of age. Our analysis reveals progressive synaptic alterations in the inner plexiform layer, driven by early presynaptic compartment failure. These changes represent the earliest detectable phenotype associated with vision loss in this model and precede overt axonal degeneration. These findings identify early synaptic preservation as a promising therapeutic target for vision loss in Wolfram syndrome.",

This study investigates the neuroprotective effects of Platycladus orientalis ethyl acetate fraction (EAPO) on retinal M\u00fcller cells (rMc-1) under different glucose stress. Bioactive compounds in the EAPO were identified using liquid chromatography-mass spectrometry, while its cytotoxicity was assessed in vitro. The expression of gene and protein biomarkers related to neuronal survival like mammalian target of rapamycin (mTOR), mitogen-activated extracellular signal-regulated kinase 1/2 (MEK1/2), rapid accelerated fibrosarcoma-1 (Raf-1), serine/threonine kinase 1 (AKT1), vascular endothelial growth factor (VEGF), and VEGF receptor 2 (VEGFR2) in EAPO- treated rMc-1 were compared with control group under different glucose concentrations. Phytochemical analysis of EAPO revealed the presence of diterpenoids, monoterpene esters, phenolic glycosides, and saturated fatty acids. EAPO demonstrated low cytotoxicity (IC50 = 0.32 mg/mL) in rMc-1 under high-glucose stress conditions. Mechanistic study showed that EAPO treatment significantly mitigated glucose-induced cytotoxicity and neurodegeneration by downregulating the expression of VEGF, VEGFR2, mTOR, Raf-1, and MEK1/2, while enhancing phosphorylation of AKT1. Co-treatment with AICAR, an activator of AMP- activated protein kinase (AMPK), further amplified the neuroprotective effects of EAPO. In contrast, inhibition of AMPK using compound C exacerbated glucose-induced cytotoxicity and neurodegenerative signaling. The combination of EAPO and AICAR synergistically inhibited VEGF/VEGFR2 signaling and its downstream pathways (mTOR and Raf- 1/MEK1/2) while promoting AKT1-mediated neuronal survival. This study provides new mechanistic insight into the neuroprotective effects of P. orientalis on rMc-1 under diabetic stress. EAPO could attenuate high-glucose-induced neuronal toxicity in rMc-1 by modulating the AKT1/mTOR and Raf-1/MEK1/2 pathways through AMPK activation.",

This retrospective cross-sectional study evaluated the frequency of sensory and entrapment neuropathies in 114 patients with ALS using electrodiagnostic (EDX) studies. Demographic characteristics, comorbidities, and sensory and autonomic symptoms were documented. Electrophysiological evidence of sensory neuropathy was identified in 20 patients overall (20/114, 17.5%), including 10 patients without diabetes mellitus (DM), whereas entrapment neuropathy was detected in 28 patients overall (28/114, 24.6%), including 16 of those without DM or hypothyroidism. Sensory neuropathy was significantly associated with both DM and a history of chronic disease. In contrast, these comorbid conditions were not significantly associated with entrapment neuropathy. Furthermore, patient-reported symptoms showed no correlation with electrophysiological evidence of sensory involvement on EDX. Sensory neuropathy was more frequent in patients with spinal-onset than bulbar-onset disease, although the difference was not statistically significant. This study confirms that sensory involvement is not uncommon in ALS. Although clinical symptoms are poor predictors, electrophysiological abnormalities consistent with sensory and entrapment neuropathies are common. A significant proportion of these abnormalities are idiopathic and may directly reflect the disease process itself, particularly in spinal-onset cases.",

Accumulating evidence has supported that cognitive impairment and Type 2 Diabetes Mellitus (T2DM) share common pathological mechanisms. The current investigation explored potential benefits of alogliptin, a dipeptidyl peptidase IV (DPP-4) inhibitor, on diabetes induced cognitive impairment by revealing its role in attenuating neuroinflammatory pathways. T2DM was induced with a high-fat diet (HFD) for 8 weeks followed by a single low dose of streptozotocin (STZ, 30\u202fmg/kg I.P). Rats of the treatment groups received alogliptin at different doses (20\u202fmg/kg/day or 40\u202fmg/kg/day) for 28 days. Memory function was assessed using the Morris Water Maze (MWM) and Y-maze tests. Blood samples were withdrawn at the end of the experiment, and brain tissue was dissected for biochemical, immunohistochemical, and histopathological examination. Alogliptin reduced diabetes-induced cognitive impairment evident in memory tasks, alleviated histological changes in the brain and attenuated oxidative stress by increasing SOD, CAT and GSH levels while reducing MDA levels. Alogliptin also decreased neuroinflammatory signaling via reducing HMGB1, RAGE, TLR4/ NF-\u03baB which in turn decreased inflammatory cytokines TNF-\u03b1 and IL-1\u03b2. Alogliptin also refined mTOR signaling pathway and improved neuronal health. According to these findings, alogliptin reduces neuroinflammation and alters mTOR action leading to the improvement of neurodegeneration and memory function.",

This study investigated whether maternal hyperglycemia induces persistent molecular and behavioral alterations in aged male offspring and whether maternal palmitoleic acid supplementation exerts protective effects. Methods: The pregnant rats were divided into four groups: PCM, PDM, PDM/CPA, and PDM/TPA. Male offspring were analyzed at 48 weeks of age. Results: Maternal hyperglycemia significantly increased cerebral RAGE expression (~1.6-fold) and tau phosphorylation (~1.8-fold), accompanied by reduced Akt phosphorylation, impaired Nrf2-related antioxidant responses, and increased inflammatory gene expression. These molecular alterations are associated with impaired recognition memory, as reflected by a marked reduction in the discrimination index in the novel object recognition test. Maternal CPA/TPA supplementation partially attenuated these abnormalities. Conclusions: These findings suggest that maternal hyperglycemia may induce long-lasting molecular alterations associated with neuroinflammation, impaired insulin-related signaling, and cognitive dysfunction in aged offspring. Maternal palmitoleic acid supplementation may partially mitigate the adverse developmental alterations associated with intrauterine hyperglycemic exposure.",

Glaucoma is likewise increasingly recognized as an age-related disorder. Across these conditions, converging patterns of neurodegeneration and microvascular injury contribute to age-associated ocular decline. Structural and neuronal degeneration of the retina, including loss of retinal ganglion cell axons, along with impaired microvascular circulation and chronic inflammation, contribute to the pathogenesis of glaucoma, AMD, DR, and RVO. Geroprotectors, a class of longevity-promoting pharmacologic agents investigated for systemic benefits in cardiovascular and neurological aging, have therefore drawn growing ophthalmic interest for their potential relevance to ocular health and the management of age-associated eye diseases. These agents are now frequently encountered as concomitant medications in ophthalmic practice, yet their ocular effects remain incompletely characterized, variably reported, and in some cases controversial. Glucagon-like peptide-1 (GLP-1) receptor agonists, widely used for glycemic control and increasingly for weight management, have been associated with reduced risk of age-related glaucoma but also with unconfirmed reports of severe nonarteritic anterior ischemic optic neuropathy. Similar uncertainties surround other geroprotective, metabolic, and weight-modifying therapies, creating challenges for clinicians attempting to incorporate evolving pharmacologic evidence without compromising patient safety. This review synthesizes reported therapeutic and adverse ocular outcomes across geroprotective agents to support clinical awareness, identify knowledge gaps, and guide future investigation. The agents reviewed include GLP-1 receptor agonists, metformin, sodium-glucose cotransporter-2 inhibitors, statins, cannabinoids, calcium channel blockers, spermidine, taurine, nicotinamide adenine dinucleotide precursors, rapamycin, and mifepristone.",

While one of the early symptoms of both Alzheimer's disease (AD) and DM-related ADRD is a reduction in cerebral blood flow, the underlying biological mechanisms driving this decline remain to be fully elucidated. Genome-wide association studies have linked AD/ADRD to single-nucleotide polymorphisms in the gene encoding soluble epoxide hydrolase (sEH), an enzyme we previously reported to be upregulated in the brains of an AD rat model. Our previous work also demonstrated that chronic inhibition of sEH with 1-trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl) urea (TPPU) preserves hippocampal-dependent spatial learning and memory and improves cerebral hemodynamics in both AD and DM-ADRD models. In the present study, we found that chronic TPPU treatment (1 mg/kg/day for 9 weeks) reduced brain sEH expression, improved cortical-based long-term non-spatial recognition memory involving both cortical and hippocampal networks, and reduced anxiety in DM-ADRD rats. TPPU improved brain perfusion and normalized impaired whisker-evoked functional hyperemia, an effect linked to upregulation of Kir2.1 expression in cerebral capillaries. Furthermore, TPPU restored tight junction proteins (ZO-1 and OCLN), mitigated capillary rarefaction, and suppressed astrocyte and microglial activation. At the cellular level, TPPU attenuated hippocampal neurodegeneration, restored the expression of synaptic proteins (PSD95 and SY38), and reduced levels of key pro-inflammatory chemokines, including MCP-1, RANTES, and MIP-1\u03b1, in DM-ADRD. In conclusion, TPPU preserves cognitive function in DM-ADRD by mitigating cerebrovascular dysfunction, neuroinflammation, and gliosis while protecting synaptic integrity and neuronal survival, representing a promising therapeutic strategy for DM-ADRD.",
        "42285402": "ID: 42285402\nTitle: Epigenetic encoding of metabolic memory in diabetic retinopathy: From molecular imprinting to neurovascular network reprogramming.\nAbstract: Diabetic retinopathy (DR) is increasingly recognized not merely as a microvascular complication, but as a chronic neurodegenerative disorder of the central nervous system characterized by progressive neurovascular unit (NVU) dysregulation. In many individuals, DR continues to progress despite subsequent glycaemic normalization, a phenomenon known as metabolic memory. Emerging evidence indicates that transient hyperglycaemic stress is converted into durable transcriptional programs through epigenetic encoding mechanisms. In this Review, we propose a hierarchical framework in which early metabolic insults are written into chromatin via DNA methylation, histone modifications, and noncoding RNA networks. Crucially, these epigenetic storage systems do not act in isolation; they systematically disrupt the intricate intercellular crosstalk within the NVU. Epigenetic locking of microglia into pro-inflammatory phenotypes, coupled with M\u00fcller cell gliosis and the suppression of neural plasticity, drives sustained pathological shifts that transform localized cellular stress into a tissue-wide network collapse. Furthermore, we critically evaluate the potential of extracellular vesicle-mediated communication in amplifying this memory across the NVU. By targeting the fundamental epigenetic drivers of glial reactivity and neurodegeneration across the integrated NVU, this Review highlights innovative strategies, such as programmable epigenetic editing (CRISPR/dCas9), to reset homeostasis and offers a transformative paradigm for early intervention in DR.",

Thirty-two treatment-na\u00efve DR patients (50 eyes) without clinically significant macular edema were graded into mild, moderate, and severe non-proliferative DR (NPDR) and proliferative DR (PDR). The macula was imaged using adaptive optics scanning laser ophthalmoscopy (AO-SLO) at five subsections. Mean/minimum photoreceptor density, cell regularity, dispersion, spacing, and dark areas were recorded. Central macular thickness (CMT) and macular leakage index (MLI) were measured. The percentage of dark areas increased gradually with DR severity: 1.86\u2009\u00b1\u20091.52 (mild NPDR), 3.32\u2009\u00b1\u20091.45 (moderate NPDR), 4.22\u2009\u00b1\u20092.11 (severe NPDR), and 5.92\u2009\u00b1\u20093.06 (PDR) (P\u2009=\u20090.007). MLI also progressively increased (P\u2009=\u20090.01): 0.31\u2009\u00b1\u20090.60%, 3.47\u2009\u00b1\u20094.70%, 6.92\u2009\u00b1\u20095.44%, and 8.98\u2009\u00b1\u20093.58%, respectively.

No significant changes were observed in photoreceptor density, regularity, dispersion, spacing, CMT, or visual acuity. Dark areas observed by AO-SLO suggest photoreceptor abnormalities, indicating decreased waveguiding ability and localized dysfunction as DR progresses. The positive correlation between dark areas and macular vascular leakage implies early dysfunction of the retinal neurovascular unit (NVU) in DR, warranting further investigation.",

However, the effects of antidiabetic drugs on neurodegeneration are not completely known. Canagliflozin, a novel option for DM treatment, is a dual inhibitor of sodium glucose co-transporter type 2 (SGLT2) and acetylcholinesterase. The aim of this study is to examine the morphological features of dendrites and dendritic spines of pyramidal neurons in hippocampus of AD model treated with canagliflozin. The model of AD was obtained by intracerebroventricular injection of streptozotocin. Then, the rats were divided into 3 groups: vehicle, donepezil, and canagliflozin. The injections were i.c.v. administered for 7 days. Behavioral tests were performed to evaluate memory, anxiety, and motor functions. Brain tissues were processed by Golgi impregnation method. Pyramidal neurons in the CA1 region were examined using Neurolucida software. Dendritic branching, total dendrite length, dendritic spine density, and dendritic spine types were analyzed. Compared to the vehicle group, the donepezil group and the canagliflozin group exhibited significantly higher dendritic branches (p\u2009=\u20090.0273, p\u2009=\u20090.0195) and total dendrite length (p\u2009=\u20090.0171, p\u2009=\u20090.0360), respectively. The total dendritic spine density (p\u2009<\u20090.0001) and the mushroom-type dendritic spine density (p\u2009=\u20090.0001) were significantly low in the donepezil group compared to the vehicle group. However, canagliflozin did not induce any significant alterations in the dendritic spine density. Canagliflozin treatment was as effective as donepezil treatment on hippocampal dendrite morphology. This morphological framework, indicating dendritic plasticity and remodeling, serve to better understand the cellular effects of canagliflozin. Therefore, our study may contribute to the development of novel strategies for therapy of AD.",

Lipopolysaccharide (LPS) is a widely used agent for inducing systemic and localized inflammation in mammals, providing a model for studying neurodegenerative processes. While previous research has documented neuronal loss due to LPS-induced neurodegeneration, the progressive morphological changes in neurons remain insufficiently characterized, particularly in retinal tissues. This study addresses this gap by establishing acute and chronic retinal inflammation models in mice using single and repeated intraperitoneal LPS injections. Through ultrastructural analyses using electron microscopy, we observed significant pathological changes in retinal neurons, glial cells, and blood-retinal barrier (BRB) components. Acute LPS exposure resulted in lipid droplet accumulation and membrane disruption in retinal pigment epithelium (RPE), as well as abnormal neuronal and vascular ultrastructures. Chronic LPS exposure amplified these effects, causing more pronounced damage to neurons and exacerbating BRB dysfunction. This study provides, for the first time, detailed ultrastructural insights into LPS-induced acute and chronic retinal inflammation. These findings advance our understanding of retinal pathology in inflammatory conditions and support the development of novel therapeutic strategies for retinal and CNS neurodegenerative diseases.",

Dysregulation of these pathways contributes to the pathogenesis of many diseases, including ocular inflammatory and neurodegenerative diseases such as glaucoma, diabetic retinopathy, age-related macular degeneration, retinitis pigmentosa, and ocular surface diseases. Our knowledge of the regulated cell death pathways, including apoptosis, necroptosis, pyroptosis, and ferroptosis, has been extensively expanded in the recent years. The targeting of these pathways as a potential therapy for various ocular diseases is now widely recognized. In recent years, it has also become clear that in many circumstances, the engagement of multiple regulated cell death pathways could be coordinated through specific cross talks to drive a stress-specific cell death and disease pathogenesis. This knowledge is extended to the recognition that targeting multiple regulated cell death pathways could be more effective for the treatment of various pathologies. However, the identity of upstream regulatory pathways and the engagement hierarchy of individual pathways and their coordinated interactions require further investigation. Here, I will briefly introduce these regulated cell death processes, discuss the key regulatory pathways involved in determining cell death or survival, as well as upstream modulators. I will also highlight studies targeting these pathways as potential treatment strategies for various eye diseases.",

We trained retinal adversarial autoencoders to represent optical coherence tomography images and color fundus photographs as 256-dimensional embeddings. Retinal adversarial autoencoder-derived embeddings were associated with a range of cardiovascular and neurodegenerative diseases, including ischemic heart disease, cerebrovascular disease, Parkinson's disease and dementia. Examining associations across diverse omics datasets, we provide evidence linking ophthalmic imaging features to neurological and cardiovascular anatomy and function, lipid metabolism and gene sets associated with neurodegenerative pathology.

Both these structures within the central nervous system (CNS) utilize common neuro-inflammatory mechanisms because the retina is an outgrowth of the brain. Like the brain, the eye has its own physical characteristics and surface molecules as well as a tendency towards specific immune reactions. Numerous distinct neurodegenerative diseases like Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), and Frontotemporal dementia (FTD) that impact the brain present as eye symptoms, and the conventional diagnosis of these neurodegenerative disorders (NDs) is often preceded by ocular symptoms. Furthermore, several eye-specific disorders have characteristics in common with other CNS disorders. NDs and AMD share common key features, such as tau and amyloid-\u03b2 deposits, oxidative stress response, chronic inflammation, and dysregulation of microglia and m\u00fcller glia. Common pathological mechanisms include complement activation, amyloid aggregation, neuroinflammation, vascular impairment, and cell death, providing a basis for a convergent neuroimmune axis between retinal and cerebral degeneration. Comparing these age-related diseases will facilitate the identification of shared risk factors, convergent molecular pathways, and potential cross-applicable therapeutic strategies, such as anti-inflammatory, anti-complementary, anti-apoptotic, and anti-VEGF-based approaches. This knowledge may enhance understanding of neurodegenerative diseases, help identify early biomarker development for diagnosis, and enable the design of targeted therapeutic strategies.",

Moderation analyses examined the IL-8\u2009\u00d7\u2009T2DM interaction on cognitive trajectories, amyloid-\u03b2 (A\u03b2) accumulation, and regional atrophy, adjusting for key covariates.ResultsIn the T2DM group, higher baseline IL-8 was significantly associated with a slower longitudinal increase in Clinical Dementia Rating-Sum of Boxes (p\u2009=\u20090.005), indicating preserved clinical function. Furthermore, elevated IL-8 in the T2DM cohort correlated with lower hippocampal A\u03b2 burden (p\u2009=\u20090.041) and attenuated atrophy rates in the parahippocampal cortex (p\u2009=\u20090.044).

Despite advances in screening and treatment, including panretinal photocoagulation (PRP), intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents, and pars plana vitrectomy (PPV), outcomes remain heterogeneous: many eyes stabilise, whereas others progress to vitreous hemorrhage, tractional retinal detachment, or neovascular glaucoma despite apparently adequate therapy. This review synthesizes current knowledge on the pathophysiology, morphological phenotypes and treatment paradigms of PDR, with a specific focus on predictors of onset, progression, and recurrence. PDR is contextualised as a multifactorial neurovascular and inflammatory disease, integrating data on hypoxia-driven angiogenesis, glial activation, microvascular rarefaction, neurodegeneration, and vitreoretinal interface remodeling. Histopathological and multimodal imaging characteristics of neovascular complexes and the vitreoretinal interface are described, highlighting how phenotypes on color fundus photography, widefield fluorescein angiography, optical coherence tomography (OCT), and OCT angiography relate to ischemic burden and clinical behaviour. Systemic, ocular, imaging, biomarker, and genetic factors associated with progression from non-proliferative diabetic retinopathy to PDR and with progression within established PDR after PRP, anti-VEGF therapy, and PPV are critically appraised. Across modalities, younger age, diabetes duration, poor glycemic control, renal disease, extensive non-perfusion, high neovascular burden, complex fibrovascular proliferation, and incomplete or unsustained treatment consistently emerge as determinants of guarded outcomes. Outstanding gaps in mechanistic understanding, risk stratification, regenerative therapy, and implementation are identified, alongside a proposed research agenda aimed at delivering mechanistically grounded risk-prediction tools and disease-modifying interventions for PDR.",

Although brain cholesterol metabolism operates largely independently of peripheral lipid pools, it is highly susceptible to disruption, particularly in the insulin-resistant ApoE4 genotype. This review follows a structured literature approach using PubMed, Scopus, and Web of Science (2000-2025) to critically evaluate mechanistic and translational evidence on cholesterol- T2DM-AD interplay. It critically evaluates current evidence on cholesterol production, transport, and elimination in the Central Nervous System (CNS), focusing on the roles of astrocytes, neurons, and transporters such as ATP-binding cassette transporter A1 (ABCA1). It also explores how peripheral metabolic stress in T2DM affects central cholesterol homeostasis and contributes to amyloid- beta (A\u03b2) accumulation and neurodegeneration. Pharmacological approaches targeting cholesterol regulation, including statins, liver X receptor (LXR) modulators, and glucagon-like peptide-1 (GLP-1) receptor agonists, are discussed. Findings indicate that impaired cholesterol regulation disrupts neuron-astrocyte interactions, enhances A\u03b2 deposition, and accelerates neurodegeneration. Controversies remain regarding the relative impact of peripheral vs. central cholesterol imbalance and Blood-Brain Barrier (BBB) permeability in therapy. In T2DM, peripheral insulin resistance and hypercholesterolemia exacerbate central cholesterol imbalance, thereby intensifying AD pathology. Emerging therapeutic studies suggest that modulation of cholesterol pathways may reduce neuroinflammation, promote A\u03b2 clearance, and slow cognitive decline. The overlap between T2DM and AD highlights cholesterol metabolism as a pivotal pathogenic axis. While peripheral factors worsen central dysregulation, CNS-specific disturbances independently drive disease progression. Targeted modulation of cholesterol pathways, through statins, LXR modulators, and GLP-1 agonists, shows promise but demands precision approaches tailored to genotype and BBB permeability. The cholesterol-AD-T2DM axis represents a promising therapeutic target. Addressing cholesterol dysregulation could enable novel, personalized strategies to mitigate neurodegeneration and cognitive decline.",

Current therapies primarily target late-stage vascular complications and do not adequately address the upstream mechanisms involved in DR onset and progression. Minocycline, a second-generation semisynthetic tetracycline with high lipophilicity, has emerged as a promising therapeutic candidate because of its pleiotropic pharmacological effects beyond antimicrobial activity. Accumulating experimental evidence indicates that minocycline exerts anti-inflammatory, anti-apoptotic, mitochondrial-protective, and potentially epigenetic regulatory effects in diabetic retinal tissues and cellular models. Mechanistically, minocycline suppresses microglial activation, attenuates pro-inflammatory signaling, stabilizes the blood-retinal barrier, preserves mitochondrial function, inhibits matrix metalloproteinase activity, and has been associated with changes in histone acetylation and methylation under diabetic conditions. These actions may help preserve retinal neurovascular integrity and reduce neuronal and microvascular injury in experimental DR models. Despite promising preclinical findings, clinical evidence remains limited. Early-phase clinical studies indicate that oral minocycline is generally well tolerated; however, its efficacy has not been established in adequately powered clinical trials. This review summarizes the pharmacological properties of minocycline, critically examines its molecular mechanisms in DR pathogenesis, and discusses current clinical evidence, translational challenges, and future research directions. Although available data support further investigation of minocycline for DR, additional preclinical and clinical studies are needed to determine its therapeutic efficacy and clinical applicability.",

This study investigated the impact of DM on nigrostriatal dopaminergic vulnerability independently of disease severity in drug-na\u00efve PD patients. This study analyzed two independent cohorts of PD patients (multi-center PPMI n\u2009=\u2009174, single-center UniBS n\u2009=\u200995). Patients with and without DM were first compared and then matched for age, sex, and clinical severity. All patients underwent baseline 123I-FP-CIT imaging to quantify dopamine transporter binding. Dopaminergic binding, neural reserve index and molecular connectivity patterns were compared between severity-matched groups. Patients with DM were older, predominantly male, and exhibited worse non-motor and cognitive symptoms. After severity matching, PD-DM exhibited more preserved nigrostriatal dopamine uptake compared to PD-n. PD-DM also showed fewer nigrostriatal dopaminergic connectivity alterations (10% vs. 21%) and reduced neural reserve index in the left putamen and - only in the single-center cohort- whole striatum. In drug-na\u00efve PD patients, comorbid diabetes is associated with comparable clinical severity despite milder dopaminergic loss. This suggests an increased dopamine system vulnerability linked to DM, reducing the efficiency and compensatory mechanisms of nigrostriatal dopaminergic networks in PD.",

They affect the central nervous system, including the brain-manifesting, for example, as dementia-as well as the retina, as seen in glaucoma or age-related macular degeneration. Malnutrition-defined as quantitative or qualitative under- or overnutrition-affects key mechanisms that contribute to neuronal and retinal neurodegeneration. OBJECTIVE: The aim of this study is to systematically present the pathophysiological mechanisms of malnutrition-related neurodegeneration, to evaluate the current evidence on dietary patterns and cognitive health, and to derive practical clinical strategies for nutritional optimization. METHODS: Narrative literature review based on peer-reviewed publications from the fields of nutritional medicine, geriatrics, neurology, ophthalmology, and public health. RESULTS: Malnutrition promotes oxidative stress, mitochondrial dysfunction, chronic neuroinflammation, and vascular dysregulation, and it influences neurotransmitter synthesis. These mechanisms are relevant to both cerebral and ocular neurodegenerative processes. The Mediterranean diet and the MIND diet are associated with a significantly reduced risk of cognitive impairment; for ocular diseases, interventional studies in age-related macular degeneration in particular demonstrate protective effects of antioxidant supplementation, whereas evidence for glaucoma is currently based predominantly on observational data. Screening approaches and micronutrient diagnostics enable early identification of at-risk individuals. Building on this, individualised dietary interventions and targeted supplementation of selected nutrients could be potentially preventive and stabilising therapeutic strategies. CONCLUSION: Malnutrition is a key modifiable risk factor for neurodegenerative diseases of the brain and retina. More intense integration of nutritional diagnostics and therapy into neurological, geriatric, and ophthalmological care structures appears warranted. Neurodegenerative Erkrankungen stellen angesichts des demografischen Wandels eine zunehmende Herausforderung f\u00fcr das Gesundheitswesen dar.

We investigated the protective role of Humanin (HN), a mitochondria-derived peptide with known neuroprotective effects in A\u03b2-related neurodegenerative diseases, in retinal pathology induced by subretinal injection of FITC-labeled A\u03b2. HN enhanced the clearance of A\u03b2-accumulated mitochondria in the RPE while preserving retinal function and RPE barrier integrity. In ARPE-19 cells, HN activated AMP-activated protein kinase (AMPK), leading to phosphorylation of ULK1 and Beclin1, which promoted the interaction between Beclin1 and Parkin and their translocation to mitochondria. This process facilitated the removal of A\u03b2-accumulated mitochondria in the RPE. Our results demonstrate that targeting mitophagy in the RPE with HN may offer a promising therapeutic strategy for AMD.",

Berberine (BBR), a natural compound used in the treatment of diabetes and diabetes-associated cognitive dysfunction (DACD), although the underlying mode of action remains largely unknown. Herein, we investigated whether nuclear factor erythroid 2-related factor 2 (Nrf2), a redox-associated factor, is essential to the neuroprotective action of BBR. Streptozotocin (STZ; 100\u00a0mg/kg IP, single shot) was used for induction of T2DM in mice. BBR was administered before STZ administration in Pre-treatment group and after STZ administration in Post-treatment group for 4 weeks. Learning and memory was assessed using Y-maze test and Step through passive avoidance task. The impact of BBR on tight junction proteins, VEGF, GLUT receptors and Nrf2/HO-1 signaling in the hippocampus was analyzed using qPCR. Using standard biochemical tests, the activity of AChE and ChAT were assessed in the hippocampus of T2DM mice. Our findings indicate that BBR significantly improved cognition in T2DM mice. It significantly increased the gene expression of tight junction proteins and VEGF in the hippocampus of T2DM mice. Also, BBR improved glucose uptake by upregulating GLUT receptors. Furthermore, a marked elevation of AChE activity and decreased activity of ChAT was seen in STZ treated mice which upon treatment with BBR was reversed. Moreover, the expression of Nrf2 and its downstream genes was reduced in the diabetic group and was significantly reversed upon BBR treatment. Taken together, our results demonstrate that BBR may exerts protective effects against cognitive decline, by decreased BBB permeability, enhanced glucose uptake, enhanced neurogenesis and activation of Nrf2/HO-1 signaling in the hippocampus of T2DM mice. Our study may signify a new mode of action and a novel therapeutic target for DACD.",

We investigated whether ONL thickness provides a subtype-informative retinal signal for differentiating PET-supported probable FTLD-tau (pFTLD-tau) from probable FTLD-TDP (pFTLD-TDP) in vivo. Patients clinically diagnosed with FTLD were subtyped into pFTLD-tau and pFTLD-TDP groups based on multimodal PET and clinical criteria. Normal controls (NCs) were cognitively unimpaired on standardized testing and clinical evaluation. Macular images were acquired using swept-source OCT. A custom deep learning algorithm segmented the retina into eight sublayers. The thickness of each retinal sublayer was assessed across the eight sectors of the Early Treatment Diabetic Retinopathy Study (ETDRS) grid. Retinal thickness differences were analyzed using generalized estimating equations, and exploratory discrimination models were evaluated using age- and sex-adjusted stepwise logistic regression with apparent and bootstrap optimism-corrected AUCs reported. Exploratory partial correlation analysis was conducted to examine the associations between ONL thickness and cognitive scores. A total of 86 participants were included (21 pFTLD-tau, 27 pFTLD-TDP and 38 NCs). Widespread ONL thinning was observed in pFTLD-tau (Cohen's d= -0.753 to -1.268 vs. controls; -0.666 to -1.069 vs. pFTLD-TDP; all FDR-adjusted P\u2009<\u20090.05), while ONL in pFTLD-TDP remained preserved. A model combining retinal nerve fiber layer (RNFL), ONL, and myoid-ellipsoid zone (MEZ) thickness showed exploratory discrimination for differentiating pFTLD-tau from pFTLD-TDP (apparent AUC, 0.922; optimism-corrected AUC, 0.866). The outer thickness model yielded higher AUC estimates than the inner thickness model (0.884/0.835 vs. 0.713/0.630), and the individual ONL model showed moderate exploratory discrimination (0.808/0.765). ONL thickness was correlated with cognitive scores in pFTLD-tau (partial r\u2009=\u20090.433-0.483; all P\u2009<\u20090.05), whereas corresponding associations in pFTLD-TDP did not reach statistical significance. ONL thinning was preferentially observed in pFTLD-tau and contributed to exploratory discrimination between PET-supported probable FTLD subtypes. These findings suggest that ONL thickness may provide complementary, noninvasive information for probable FTLD subtype stratification, with potential to facilitate therapeutic trial enrollment and personalized management. Future studies incorporating neuropathological confirmation and fluid biomarkers are warranted to validate these findings.",

Among these pathways, cyclic guanosine monophosphate (cGMP) signaling plays a central role in photoreceptor function and survival. Phosphodiesterase 6 (PDE6), the key enzyme responsible for cGMP hydrolysis in photoreceptors, has been extensively studied in inherited retinal disorders; however, its regulation under diabetic and redox-imbalanced conditions remains insufficiently defined. In this review, we examine the emerging role of redox imbalance in modulating PDE6 activity and stability in the diabetic retina. We discuss how mitochondrial and non-mitochondrial sources of reactive oxygen species (ROS) may disrupt PDE6 through proteostasis-related mechanisms involving AIPL1-dependent maturation and FAT10-mediated degradation. These alterations may lead to cGMP dysregulation, impaired ion channel activity, calcium imbalance, and photoreceptor dysfunction. We propose that PDE6-cGMP signaling represents a redox-sensitive hub linking oxidative stress to early neuronal damage in diabetic retinopathy. This mechanistic framework highlights PDE6 as a potential molecular target and supports the development of redox-based strategies aimed at preserving retinal function and preventing neurodegeneration.",
        "42342866": "ID: 42342866\nTitle: Bioenergetic failure in diabetic peripheral neuropathy: from glucotoxicity to multidimensional metabolic imbalance.\nAbstract: Diabetic peripheral neuropathy (DPN), particularly distal symmetric polyneuropathy, characterized by length\u2011dependent axonal damage, is a common chronic complication of type 2 diabetes mellitus. The pathogenesis of DPN is complicated, yet one thing is clear: long axons require a great deal of energy. When axonal transport is compromised by impaired energy metabolism, neuronal somata fall into an energy deficit that triggers neurodegeneration. While earlier work centered on hyperglycemia-induced cytotoxicity, recent studies have increasingly implicated dysregulation of glucose, lipid, and amino acid metabolism as key contributors to DPN. In this review, we integrate the anatomical organization of peripheral nerves, bioenergetic pathways, and axon-Schwann cell interactions to establish a framework for understanding how glucose, lipid, and amino acid dysregulation converge to induce bioenergetic failure in DPN. Based on these mechanisms, we further discuss novel strategies aimed at restoring metabolic homeostasis in neurons and Schwann cells. Importantly, correcting a single metabolic pathway is unlikely to halt or reverse DPN. Instead, restoring global energy homeostasis to rebalance axonal energy supply and demand may be essential for preserving peripheral nerve function.",
        "42344673": "ID: 42344673\nTitle: Magnetoencephalography biomarkers for assessing myelin content and neuronal function in acute optic neuritis.\nAbstract: The visual pathway is an important model system for remyelination and neuroprotection trials in multiple sclerosis, due to its accessibility and the availability of validated methods including visual evoked potential and optical coherence tomography. However, visual evoked potentials are sometimes undetectable and demonstrate limited reliability after acute optic neuritis. This study aims to investigate novel magnetoencephalography markers for assessing myelin content and neuronal dysfunction in the early phase of optic neuritis and describes their inter-run reproducibility ('over a single visit') and association with short-term visual outcomes. Patients with unilateral acute optic neuritis were recruited and underwent ophthalmological assessments, brain MRI and magnetoencephalography. Magnetoencephalography data were acquired during visual stimulation with an alternating checkerboard pattern. We used source localization to reconstruct brain activity in the primary visual cortex (V1) and analysed it in the temporal and frequency domains. In the temporal domain, we focused on M100 latency-the magnetic counterpart of P100 latency. In the frequency domain, we assessed the spectral richness of the steady-state evoked field response by harmonic count, which reflects the diversity of frequency components present in the brain signal. Thirty-two patients were included at a median of 54 days [interquartile range = (37.5-78)] post-symptom onset of optic neuritis. Among patients with optic neuritis, visual evoked field recordings were detectable in 77% of cases, compared with 66% for visual evoked potential recordings. M100 latency demonstrated an excellent inter-run reproducibility for both fellow and affected eyes [intra-class correlation coefficient (ICC) >0.8, mean absolute inter-run difference of 2.99 \u00b1 6.53 and 3.76 \u00b1 7.53\u2005ms, respectively]. By comparison, the reproducibility of P100 latency was good for fellow eye (ICC = 0.7, mean absolute inter-run difference of 3.9 \u00b1 6.2\u2005ms) but moderate for affected eye (ICC = 0.6, mean absolute inter-run difference of 9.1 \u00b1 21.8\u2005ms). In the frequency domain, the harmonic count correlated strongly with ganglion cell layer volume (r = 0.68, P = 0.0001), likely reflecting functional consequences of neuronal loss. Measures reflecting demyelination (P100 and M100 latencies) correlated with measures of neuronal damage (ganglion cell layer volume and harmonic count) from both conventional and magnetoencephalography assessments. Visual impairment was associated with neuronal damage (parameter estimates: \u03b2 = 0.49, P = 0.017 for ganglion cell layer volume, \u03b2 = 0.57, P = 0.003 for harmonic count) but not with demyelination measures. Our results highlight magnetoencephalography as a reproducible and comprehensive tool to study both myelin content and neuronal dysfunction shortly after optic neuritis and suggest that, at this early stage, neuronal damage is already the main driver of visual outcome.",

Such a bioactive compound may also be useful for treating neurodegenerative diseases like age-related macular degeneration (AMD). Our research focuses on AMD-related pathomechanisms using primary porcine retinal pigment epithelium (RPE) cells in vitro and zebrafish (Danio rerio) models in vivo. We tested the bioactivity of a commercially available fucoidan (FVs) from bladderwrack with regard to pathomechanisms of AMD. We performed multiplex assays, RT-qPCR and fluorescence-based assays for the formation of nitric oxide (DAF-FM assay) and reactive oxygen species (DCF-DA assay) to analyze angiogenesis-related chemokines and pro-inflammatory cytokines as well as protection against oxidative stress and inflammatory insult. Our results showed that FVs significantly reduced the secretion of pro-angiogenic vascular endothelial growth factor A (VEGF-A) and follistatin as well as the pro-inflammatory cytokines interleukin 8 (IL-8) after lipopolysaccharide (LPS) and polyinosinic/polycytidylic acid (PIC) induction. Interleukin 6 (IL-6) was also reduced in the supernatant of the RPE cells. Additionally, in zebrafish, fucoidan decreased the production of NO and ROS. Gene expression of zebrafish embryos revealed anti-inflammatory effects by suppressing pro-inflammatory genes and significantly downregulating, e.g., interleukin 1 beta (IL-1\u03b2). These findings indicate modulation of oxidative stress, inflammatory responses, and VEGF secretion of the used FVs. This study demonstrates that fucoidan possesses AMD-relevant bioactivities in vitro and in vivo, suggesting fucoidan warrants further investigation in AMD-related research and related pathological mechanisms.",

IL-17 is a proinflammatory cytokine implicated in diabetes-related microvascular and ocular inflammatory processes, particularly in diabetic retinopathy, whereas DEL-1 is an endogenous anti-inflammatory molecule that counter-regulates IL-17-mediated immune responses and contributes to vascular and immune homeostasis. Aqueous humor samples were collected during cataract surgery from type 2 diabetic cataract patients without diabetic retinopathy (n\u2009=\u200933) and from non-diabetic cataract patients serving as controls (n\u2009=\u200928). DEL-1 and IL-17 concentrations were measured using enzyme-linked immunosorbent assay (ELISA). Correlation analyses were performed to explore the associations between biomarker levels and clinical parameters, including age, duration of diabetes, fasting blood glucose, HbA1c, and macular thickness. Mean aqueous humor DEL-1 levels were 0.27\u2009\u00b1\u20090.21\u00a0pg/mL in diabetic cataract patients without retinopathy and 0.36\u2009\u00b1\u20090.30\u00a0pg/mL in non-diabetic controls. Mean IL-17 levels were 59.82\u2009\u00b1\u200922.16\u00a0pg/mL and 59.78\u2009\u00b1\u200920.73\u00a0pg/mL, respectively. No statistically significant differences were observed between the groups for either biomarker (p\u2009=\u20090.305 for DEL-1; p\u2009=\u20090.839 for IL-17). Aqueous humor DEL-1 and IL-17 levels were not significantly elevated in diabetic cataract patients without diabetic retinopathy, and their potential diagnostic value for detecting subclinical ocular inflammation during the pre-diabetic retinopathy stage remains to be clarified. The findings indicate that local immune responses, rather than systemic diabetes alone, may play a more critical role. Further research is warranted to clarify their clinical applicability.",

To determine if retinal layer thickness changes on optical coherence tomography (OCT) imaging were associated with glycemic outcomes and DRD in youth. This prospective cohort study was conducted at an academic pediatric diabetes center among youth with T1D aged 9 to 21 years participating in the ACCESS2 (AI for Pediatric Diabetic Eye Exams Study 2) study. Participants were enrolled and data were collected July 11, 2022, and April 30, 2025. Data analysis was performed from June 2025 through October 2025. OCT imaging. The primary outcome was macular OCT volumes, which were segmented by the Topcon Maestro camera software and reviewed by the Wisconsin Reading Center for 3 neuroretinal layers: (1) retinal nerve fiber layer (RNFL) thickness, (2) ganglion cell and inner plexiform layer (GCL+IPL) thickness, and (3) GCL+IPL+RNFL thickness, as well as total retinal thickness. Layer thicknesses were analyzed for associations with glycemic outcomes and DRD and for potential covariates. A total of 294 youth with T1D (n\u2009=\u2009578 eyes), among whom mean (SD) age was 15.8 (2.8) years, 153 participants (52.0%) were female, and 108 participants (36.7%) had public insurance, were included. Participants had a median (IQR) duration of diabetes of 7.0 (4.6-10.1) years and a median (IQR) hemoglobin A1c (HbA1c) of 8.5% (7.5%-9.9%); 210 participants (71.4%) used an insulin pump. Of the total 578 eyes, 65 eyes (11.2%) had mild DRD and 10 eyes (1.73%) had moderate DRD. In adjusted analyses, moderate DRD vs no DRD was associated with RNFL thickness of -1.2 \u00b5m (95% CI, -2.9 to 0.5; P\u2009=\u2009.20), GCL+IPL thickness of -1.2 \u00b5m (95% CI, -2.8 to 0.4; P\u2009=\u2009.19), and outer retinal layer thickness of -0.8 \u00b5m (95% CI, -3.9 to 2.2; P\u2009=\u2009.80). In multivariable models, GCL+IPL and outer retinal layer thickness were associated with HbA1c (\u03b2\u2009=\u2009-0.39; 95% CI, -0.78 to -0.01; P\u2009=\u2009.04; and \u03b2\u2009=\u2009-0.81; 95% CI, -1.49 to -0.12; P\u2009=\u2009.02, respectively).

Extracellular vesicles (EVs) have emerged as critical mediators of intercellular communication and are increasingly implicated in the pathogenesis and progression of diabetes. This review summarizes current knowledge on EV biology, including their classification, cellular sources, biogenesis, uptake mechanisms, and molecular cargo. We discuss the contribution of EV-associated microRNAs to immune dysregulation and \u03b2-cell damage in type 1 diabetes mellitus (T1DM), as well as the role of EVs in insulin resistance, metabolic signaling, and vascular dysfunction in type 2 diabetes mellitus (T2DM). Particular emphasis is placed on EV-mediated modulation of endothelial function, angiogenesis, and tissue repair, alongside their involvement in the impairment of insulin receptor integrity. We further explore how lifestyle factors may influence EV composition and function, highlighting their potential integration into preventive strategies. Finally, we evaluate the emerging therapeutic potential of EVs as biomarkers and delivery systems, while addressing current limitations and future directions. Collectively, EVs represent a promising frontier in understanding diabetes pathophysiology and developing innovative diagnostic and therapeutic approaches. Unlike previous reviews that examine EVs separately as biomarkers or therapeutic vehicles, this review integrates emerging evidence supporting EVs as mediators of systemic communication linking pancreatic islets, adipose tissue, immune cells, vascular endothelium, kidney, heart, and retina throughout diabetes progression. We further critically evaluate translational barriers that currently limit clinical implementation of EV-based diagnostics and therapeutics.",

Yet, the molecular systems that connect these processes with cardiac, vascular and neuronal complications are incompletely defined. This review examines the AGE-RAGE-DIAPH1 axis as a mechanistic link between metabolic dysfunction and diabetic myocardial and neuronal injury, with emphasis on vascular and myocardial remodeling and emerging implications for autonomic neuronal vulnerability. We summarize current evidence on the formation and accumulation of advanced glycation end-products and other RAGE ligands in metabolic disease, DIAPH1's structural and signaling role as an intracellular effector of RAGE, and the cellular consequences of pathway activation in vascular, neural, and cardiac tissues. Across experimental models, this signaling axis promotes oxidative stress and inflammatory activation, leading to endothelial dysfunction and barrier failure. Subsequent fibrotic remodeling provides a biologically plausible route through which metabolic stress may be translated into persistent organ injury. In the heart, these mechanisms are linked to coronary microvascular dysfunction, altered cardiomyocyte phenotype, calcium handling abnormalities, and myocardial fibrosis. In the autonomic nervous system, limited but emerging data connect RAGE activation to oxidative injury and mitochondrial dysfunction, abnormal neuronal excitability, and structural vulnerability. Direct evidence linking DIAPH1 to autonomic neurons is lacking. We also review biomarker candidates related to this pathway, including circulating AGEs and soluble RAGE isoforms, skin AGE measurements, imaging markers of myocardial remodeling, and autonomic functional measures. Finally, we discuss pharmacological and natural compounds that target AGE formation, ligand accumulation, RAGE signaling, or intracellular protein interactions linked to this axis. Overall, the available evidence supports the AGE-RAGE-DIAPH1 axis as a credible mechanistic concept and a potentially informative translational hypothesis in T2DM. However, the AGE-RAGE component is supported more strongly than DIAPH1-specific involvement in human diabetic myocardial disorder or cardiovascular autonomic neuropathy. The value of DIAPH1 as a biomarker or therapeutic target in these neurocardiac complications remains to be established.",

Repeat-associated non-AUG (RAN) translation of the expanded repeat generated dipeptide repeat proteins (DPRs), which disrupted multiple cellular processes and contributed to neurodegeneration. Emerging evidence indicated that disease pathogenesis involved both gain-of-function (GOF) and loss-of-function (LOF) mechanisms. DPR-mediated GOF toxicity induced ribosomal dysfunction, nucleolar stress, proteostatic impairment, and neuronal injury, whereas C9ORF72 LOF disrupted lysosomal and autophagic pathways in microglia, impairing the immune homeostasis. Neuronal injury further promoted the release of damage-associated signals that triggered secondary microglial activations and chronic neuroinflammations. This review summarized current knowledge of DPR biology, microglial dysfunction, and their contributions to disease progression in C9ORF72-associated ALS/FTD. Therapeutic strategies targeting repeated RNA, DPR productions, proteostasis, autophagy, and neuroinflammatory pathways were also discussed. In addition, the potentials of fluid biomarkers, including cerebrospinal fluid poly (GP) and blood neurofilament light chain (NfL), for diagnosis, disease monitoring, and therapeutic assessment were shown.

We aimed to identify which optical coherence tomography angiography (OCTA) biomarkers best distinguish eyes with T2DM without clinical DR from healthy controls and to evaluate machine learning classifiers trained on a comprehensive 68-parameter OCTA panel. Materials and Methods: In this prospective case-control study, 80 patients with T2DM without clinical DR and 33 controls underwent 3 \u00d7 3 mm macular OCTA using an Optovue RTVue Avanti System. After outlier screening, 221 eyes (155 T2DM, 66 controls) were analyzed. Sixty-eight OCTA parameters were extracted, covering FAZ morphometry (including foveal density FD-300), SCP and DCP vessel density and layer thickness, outer-retina and choriocapillaris flow, and a full retinal-thickness map. Between-group comparisons used the Mann-Whitney U test with Benjamini-Hochberg FDR correction. Logistic regression, random forest, and XGBoost classifiers were evaluated with patient-grouped 10-fold cross-validation; feature importance was quantified via SHAP. Results: Forty-two of 68 parameters reached FDR significance (q < 0.05).

FD-300 was reduced in T2DM (median 47.55% vs. 51.86%; rb = -0.57; q = 1.0 \u00d7 10-10) and emerged as the top SHAP feature (mean |SHAP| = 0.81). FAZ circularity decreased without FAZ-area enlargement, and outer-retina flow was paradoxically elevated (rb = +0.39), consistent with a projection artifact. XGBoost using all 68 features achieved a patient-grouped cross-validated AUC of approximately 0.91, compared with 0.85 for conventional SCP + DCP whole-image density. No parameter correlated with current HbA1c in T2DM (all q > 0.98), and the well-controlled (<7%) and poorly controlled (\u22657%) subgroups were indistinguishable across five of six principal biomarkers, consistent with metabolic memory. FD-300 remained independent after adjustment for hypertension, hyperlipidemia, and age (OR = 0.76; 95% CI 0.69-0.84; p < 0.001). Conclusions: A multi-compartment OCTA panel outperforms conventional two-layer vessel-density metrics in detecting preclinical diabetic microvasculopathy, although external validation is required before clinical use. FD-300 is the single most informative biomarker, while choriocapillaris and retinal thickness measures provide complementary, compartment-specific signals. Because the OCTA signature is decoupled from the current HbA1c, screening should not be deferred in well-controlled T2DM.",
        "42356170": "ID: 42356170\nTitle: Cup-to-Disc Ratio Is Associated with Disability in Multiple Sclerosis: A Combined OCT and Subjective Visual Vertical Study.\nAbstract: Background and Objectives: Non-invasive biomarkers reflecting neurodegeneration are increasingly important in multiple sclerosis (MS). Optical coherence tomography (OCT) provides quantitative measures of retinal structure, most commonly peripapillary retinal nerve fiber layer (pRNFL) thickness. However, the potential clinical relevance of optic nerve head morphology, including cup-to-disc ratio (CDR), remains insufficiently explored. We investigated associations between OCT-derived parameters, subjective visual vertical (SVV), and disability in MS. Materials and Methods: In this retrospective study, 100 patients with MS were included. OCT parameters (pRNFL thickness and area-based CDR) were analyzed at baseline and follow-up. Clinical disability was assessed using the Expanded Disability Status Scale (EDSS). Detailed optic neuritis history was not consistently available in the retrospective clinical records and therefore could not be systematically accounted for in the analyses. SVV was evaluated in 37 patients using a virtual reality-based protocol. Associations were assessed using Spearman correlation and linear regression analyses. Multivariable regression models were adjusted for age, sex, and follow-up duration. Results: pRNFL thickness was not associated with baseline EDSS (rho = -0.06, p = 0.55) or annualized EDSS change. Baseline CDR correlated with both baseline EDSS (rho = 0.30, p = 0.0065) and follow-up EDSS (rho = 0.46, p < 0.0001). In univariable regression analysis, baseline CDR was associated with follow-up EDSS (B = 3.33, R2 = 0.23, p < 0.0001), remaining significant after adjustment for age, sex, and follow-up duration (B = 2.59, 95% CI 1.26-3.92, p = 0.0002). No significant associations were observed between OCT parameters and SVV measures. Conclusions: Higher CDR values, but not pRNFL thickness, were associated with disability measures in this exploratory MS cohort. However, these findings should be interpreted cautiously because optic neuritis history could not be systematically accounted for and physiological optic disc variability may substantially influence CDR measurements.",

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

Understanding the molecular changes during this transition is critical for timely identification and intervention. We performed DIA-based proteomics and untargeted metabolomics on longitudinal paired plasma samples from 15 DM patients who developed DR during 1-2 years. Differential expression, pathway enrichment, and protein-metabolite correlation analyses were performed. Key proteins were validated by ELISA in an independent cohort of 22 DM patients without DR and 22 NPDR patients, and their predictive performance for DR progression was assessed using receiver operating characteristic (ROC) curve analysis. Proteomic analysis identified 57 differentially expressed proteins enriched in energy metabolism, detoxification, and cellular defense responses. Metabolomic profiling revealed 168 differential metabolites, primarily involved in taurine and hypotaurine metabolism, neuroactive ligand-receptor interaction, and tyrosine metabolism. Integrated proteomic-metabolomic analysis revealed significant correlations between proteins and metabolites. Eight candidate proteins were validated by ELISA, including three previously reported in DR (Annexin A1 (ANXA1), Glutathione Peroxidase 1 (GPX1), Glutathione S-transferase Mu 1 (GSTM1)) and five newly identified candidates (Aldehyde Dehydrogenase 18 family member A1 (ALDH18A1), Galactose-1-Phosphate Uridylyltransferase (GALT), Proteoglycan 2 (PRG2), Ubiquitin-activating Enzyme E1 (UBA1), Glucagon (GCG)). ROC analysis demonstrated strong discriminative performance for these proteins, with area under the curve (AUC) values ranging from 0.853 to 0.945. Our study reveals coordinated alterations in plasma proteins and metabolites during the progression from DM to DR. Integrated multi-omics analysis identified five novel candidate biomarkers, which may serve as potential targets for early detection and risk stratification of DR.",

Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease.",
        "42360388": "ID: 42360388\nTitle: Deletion of CEACAM1 does not affect retinal and choroidal morphology or transcriptome.\nAbstract: CEACAM1 (CC1) is an important mediator of cell proliferation and adhesion and serves as an angiogenic factor through interaction with VEGF. Although the role of CC1 has been extensively studied in organs such as the heart, liver and lung in which CC1 is considered an important regulator of various pathological conditions, little is known about the function of CEACAM1 in the eye. In this study, we investigated the expression and function of CC1 in the retina and choroid of healthy adult mice using immunohistochemistry, fluorescence activated cell sorting (FACS) and RNA sequencing. We found CC1 to be expressed in endothelial and myeloid cells of the retina and the choroid. However, deletion of CC1 did not result in vascular abnormalities of the retina and choroid or changes in retinal myeloid cell morphology and number. Furthermore, the retinal architecture was not affected and morphometric measurements of the thickness of the inner and outer retinal layers were not altered by deletion of CC1. Accordingly, we did not observe structural or transcriptomic changes in the choroid. Our data suggest that the role of CC1 in the adult eye during steady state is attenuated or can be compensated by other molecular mediators. However, one could speculate that CC1 may become functionally relevant during pathological conditions, such as in neovascular eye diseases like proliferative diabetic retinopathy or neovascular age-related macular degeneration.",
        "42364841": "ID: 42364841\nTitle: Chrononutrition as a modulator of retinal metabolic resilience: A translational framework linking circadian biology to ocular disease.\nAbstract: Chrononutrition-the alignment of feeding-fasting cycles with endogenous circadian rhythms-has emerged as a key determinant of systemic metabolic homeostasis. However, its relevance in ocular biology and retinal disease remains insufficiently defined within a translational framework. The retina, characterized by high energetic demand, intrinsic circadian oscillators, and tight coupling between mitochondrial function and redox balance, represents a uniquely vulnerable target to chrono-metabolic disruption. Here, we propose a mechanistically integrated model in which feeding timing acts as a systemic regulator of retinal metabolic resilience. We synthesize evidence demonstrating that circadian misalignment and irregular nutrient intake disrupt retinal bioenergetics, impair insulin signaling, and promote mitochondrial dysfunction and oxidative stress-hallmarks of major retinal diseases including diabetic retinopathy, age-related macular degeneration, and glaucomatous neurodegeneration. Particular emphasis is placed on nutrient-sensitive pathways, including peroxisome proliferator-activated receptors (PPARs), the AMPK/SIRT1 axis, and melatonin-mediated chronoregulation, as key interfaces linking metabolic cues with retinal circadian control. Importantly, we advance the concept that chrononutrition extends beyond dietary composition to function as a temporal modulator of disease-relevant pathways. Based on convergent experimental evidence, we outline a translational framework in which rhythm-aligned feeding patterns and time-dependent nutritional interventions may enhance mitochondrial efficiency, stabilize redox homeostasis, and improve retinal stress adaptation. Although direct clinical evidence remains limited, this paradigm provides a biologically grounded basis for the development of chrono-nutritional strategies as adjunctive approaches in retinal disease prevention and management.",

What are the relationships?\nAbstract: Neurological adverse events have been reported in patients receiving tumor necrosis factor inhibitors (TNFi) for the treatment of inflammatory rheumatic diseases. The occurrence of amyotrophic lateral sclerosis (ALS) during TNFi therapy is rare but raises the question of a possible relationship. We report 2 cases of ALS diagnosed during TNFi treatment: the first in a patient with spondyloarthritis treated with adalimumab and the second in a patient with seronegative polyarthritis treated with infliximab. Tumor necrosis factor alpha (TNF\u03b1) has been implicated in ALS pathogenesis and is considered to exert both neuroprotective and neurotoxic effects, depending on the differential expression of its receptors in distinct regions of the central nervous system. We also review data from pharmacovigilance databases and discuss the potential influence of TNF\u03b1 inhibition on ALS development.",

The diffusion tensor imaging along the perivascular space (DTI-ALPS) index has been proposed as a non-invasive imaging surrogate that may reflect aspects of glymphatic system activity.ObjectiveWe investigated the relationship between ALPS index, cognition, brain structure, and plasma Alzheimer's disease biomarkers in T2DM patients.MethodsTwo independent cohorts were analyzed: Cohort 1 included 60 age, sex, and education matched participants (20 T2DM with MCI, 20 T2DM with normal cognition, and 20 healthy controls); Cohort 2 comprised 35 elderly T2DM patients assessed for plasma AD biomarkers. All participants underwent MRI for ALPS index calculation and structural imaging. Cognition was evaluated using the Mini-Mental State Examination and Montreal Cognitive Assessment.ResultsThe ALPS index was significantly lower in T2DM patients with MCI compared to cognitively normal T2DM patients and healthy controls, and showed discriminative ability for MCI. Lower ALPS index correlated with poorer cognitive scores and was associated with brain atrophy. Mediation analysis indicated that the volume of the right opercular inferior frontal gyrus mediated the relationship between ALPS index and cognition scores. Furthermore, the ALPS index negatively correlated with plasma pTau217 adjusted by age and sex in T2DM patients.ConclusionsA lower ALPS index is associated with cognitive impairment, brain atrophy, and plasma tauopathy, which may serve as a promising non-invasive imaging biomarker for early identification of neurodegeneration risk in T2DM patients.",
        "42380113": "ID: 42380113\nTitle: A natural programmable metamaterial controls 3D curvature of compound eyes.\nAbstract: Panoramic vision of the convex compound eyes, common to insects and crustaceans, relies on micrometer-scale curvature variations. These variations generate specialized visual zones adapted to specific tasks, including detecting prey, mates, or predators. However, how such fine-scale curvature is encoded during development remains unknown. We find in Drosophila melanogaster that the basal surface of the developing retina is organized as a supracellular triangular mesh where the size of these triangles is distributed in a species-specific 2D pattern. Functional experiments using genetic perturbations, together with computational modeling, support the notion that this pattern guides adult eye local curvature. A similar pattern in the Drosophila mauritania developing retina indicates an evolutionary conservation of this mechanism. Our findings identify a mechanism of morphogenesis where fine-scale 3D curvature is programmed in the 2D patterning of a tissue with metamaterial properties. This mechanism provides a framework for designing shape-programmable 3D biological surfaces, with broad implications from synthetic morphogenesis to clinical applications.",
        "42383305": "ID: 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.",

We integrated clinical data from the National Health and Nutrition Examination Survey (NHANES) with an independent hospital cohort (Nantong First People's Hospital). A multi-stage feature selection pipeline (Boruta algorithm and LASSO regression) was utilized to identify core predictors. Eight ML algorithms were benchmarked. To transcend conventional \"black-box\" predictions, we coupled SHAP (SHapley Additive exPlanations) for personalized interpretability with a Bayesian Network Directed Acyclic Graph (DAG) to map the probabilistic dependency structure among the selected systemic biomarkers. The LightGBM algorithm outperformed other classifiers, yielding a robust external validation AUC of 0.841 (95% CI: 0.809-0.862). Fourteen key routine predictors were identified, spanning glycemic control, renal function, and lipid metabolism. Crucially, probabilistic dependency structure via the Bayesian Network revealed a hierarchical pathogenetic topology: rather than parallel associations, latent renal impairment markers (urine protein, BUN, and urine creatinine) and chronic glycemic toxicity (HbA1c) emerged as direct upstream dependency drivers of DR. This structural evidence suggests a probabilistic dependency consistent with the 'kidney-eye crosstalk' hypothesis. We successfully deployed a high-performing, non-invasive LightGBM model for early DR screening. By integrating predictive ML with probabilistic dependency structure, this framework not only delivers an accessible, web-based clinical decision support system (CDSS) for resource-constrained settings but also provides preliminary insights into the potential systemic microvascular interplay driving diabetic retinopathy.",

This could link metabolic imbalance to Alzheimer's disease, Parkinson's disease, and cognitive decline. The aim of this review is to clarify the roles of adipokines in type 2 diabetes-induced neurodegeneration, their molecular pathways, and the possible neuroprotective potential of antidiabetic agents. Literature was searched in PubMed, Google Scholar, and Scopus for Englishlanguage articles published up to November 2025, using keywords like adipokines, diabetes mellitus, neurodegeneration, neuroinfl ammation, and antidiabetics. Results highlight those elevated levels of pro-infl ammatory adipokines, such as TNF-\u03b1, IL-6, and resistin, together with reduced levels of neuroprotective adipokines, including adiponectin and leptin, may drive NF-kB activation, suppression of Nrf2 signaling, and amyloid and tau pathology. This is further exacerbated by oxidative stress and mitochondrial dysfunction. Antidiabetic agents like metformin, GLP-1 agonists, thiazolidinediones, and SGLT2 inhibitors restore adipokine balance, enhance AMPK/PPAR\u03b3 signaling, and show cognitive benefits in mild cognitive impairment cohorts per clinical trials. In conclusion, repurposing antidiabetics via biomarker-guided multiple therapies offers disease-modifying promise for type 2 diabetes-linked neurodegeneration, necessitating large randomized controlled trials in prediabetic populations.

Despite a growing body of association data, translational claims in this field have frequently outpaced the evidence, and clinically actionable guidance for the practising ophthalmologist remains sparse. This review asks a deliberately narrow question: which retinal imaging domains provide evidence mature enough to inform clinical decisions about cerebrovascular risk, and which remain investigational? Narrative review of the published literature on five retinal imaging domains: (1) classical fundus signs and quantitative vessel-calibre analysis; (2) retinal vessel geometry including fractal dimension and tortuosity; (3) optical coherence tomography (OCT) structural analysis; (4) optical coherence tomography angiography (OCTA); and (5) artificial intelligence (AI) and oculomics. Evidence was appraised with emphasis on study design, population size, confounding control, external validity, and translational distance from clinical practice. The literature search was updated to March 2026. Classical retinal microvascular abnormalities and quantitative vessel-calibre metrics carry the strongest and most reproducible evidence base, particularly for cumulative vascular burden, lacunar stroke phenotypes, and cerebral small-vessel disease (cSVD). Retinal vessel fractal dimension adds incremental signal for the cSVD phenotype, with recent Mendelian randomisation data suggesting causal rather than purely associative relationships between retinal vascular morphology and stroke. OCT structural analysis shows consistent associations with ischaemic stroke and cSVD-related neurodegeneration, but the absence of validated clinical thresholds limits immediate applicability. OCTA deepens neurovascular phenotyping but is constrained by device heterogeneity, segmentation variability, and ocular confounding. AI-based oculomics, including foundation-model approaches, demonstrates credible discrimination for silent brain infarction and stroke-risk enrichment, though no randomised controlled trial has yet demonstrated that retinal AI improves cerebrovascular outcomes, and current translational limits remain substantial. Retinal imaging is best positioned as a neurovascular phenotyping tool rather than a stand-alone stroke prediction instrument. The ophthalmologist's highest-value contribution is recognising when embolic, asymmetric, clustered, or disproportionate retinal findings should lower the threshold for broader vascular assessment or neurological referral. Integration with Doppler ultrasound vascular assessment - including ophthalmic artery flow evaluation, carotid haemodynamics, and orbital haemodynamic asymmetry - substantially extends the clinical reach of retinal phenotyping and is highlighted as a mechanistically complementary dimension of extracranial cerebrovascular evaluation. This review provides a practical, pattern-based framework applicable in routine ophthalmic care.",

Berberine and metformin independently activate AMPK and may engage Nrf2-mediated antioxidant defenses, yet their combined neuroprotective interaction has not been formally quantified using validated synergy frameworks, nor has its pharmacokinetic basis been verified. Streptozotocin-nicotinamide diabetic rats were allocated to twelve groups (n\u2009=\u200913/group) receiving berberine (50, 100, 150\u00a0mg/kg/day) or metformin (100, 200, 300\u00a0mg/kg/day) monotherapy, fixed-ratio 1:2 combinations, or vehicle controls (including a non-diabetic combination group) orally for six weeks. The novel object recognition (NOR) discrimination index served as the predefined primary endpoint for Chou-Talalay combination index (CI) analysis. Hippocampal mechanistic (n\u2009=\u20096/group) and satellite LC-MS/MS pharmacokinetic (n\u2009=\u20096/group) analyses were performed. Diabetes impaired NOR discrimination index (37.2\u2009\u00b1\u20093.8% vs. 68.4\u2009\u00b1\u20093.2%; p\u2009<\u20090.001). The reference combination (100\u2009+\u2009200\u00a0mg/kg) restored NOR to 67.1\u2009\u00b1\u20093.6% with CI\u2009=\u20090.65 (95% CI: 0.43-0.91), synergism maintained across the full effect range. All six neuroinflammatory endpoints achieved Benjamini-Hochberg-corrected significance (p_adj\u2009=\u20090.006-0.043; Tier 2). Non-diabetic combination animals showed reduced AMPK activation magnitude (1.53 vs. 2.31-fold; P_adj\u2009=\u20090.067; Tier 3, hypothesis-generating). LC-MS/MS verified bioequivalent drug exposure. Berberine-metformin co-treatment is associated with CI-quantified supra-additive recognition memory recovery in diabetic encephalopathy, with neuroinflammatory suppression as the most statistically robust mechanistic correlate. Pharmacokinetic findings are consistent with a pharmacodynamic rather than pharmacokinetic basis. Causal involvement of the AMPK-Nrf2 axis remains correlative pending direct loss-of-function validation.",

Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways.

Although current therapies effectively suppress pathological neovascularization, many patients continue to exhibit persistent visual dysfunction despite regression of active disease, highlighting an unmet need for neuroprotective interventions. Sigma 1 receptor (Sig1R), an endoplasmic reticulum-mitochondrial chaperone and regulator of cellular stress responses, has emerged as a promising therapeutic target in neurodegenerative and retinal diseases. Here, we investigated whether Sig1R activation confers sustained neuroprotection following neonatal ischemic retinal injury. Wild-type and Sig1R knockout mice were subjected to oxygen-induced retinopathy (OIR) and treated systemically with the high-affinity Sig1R agonist (+)-pentazocine [(+)-PTZ]. Retinal structure and visual function were assessed longitudinally through 20 weeks of age using visual acuity, contrast sensitivity, electroretinography (ERG), pattern ERG (PERG), spectral-domain optical coherence tomography (SD-OCT), and histological analyses. Chronic Sig1R activation significantly preserved visual acuity, contrast sensitivity, rod- and ganglion cell-mediated retinal function, retinal ganglion cell survival, and inner retinal architecture in OIR mice. These protective effects were abolished in Sig1R-deficient mice, demonstrating a requirement for Sig1R in mediating neuroprotection. Mechanistically, Sig1R activation reduced apoptotic signaling, attenuated oxidative and nitrosative stress, improved mitochondrial respiratory function, and enhanced endogenous antioxidant pathways. Collectively, these findings demonstrate that Sig1R activation provides durable, receptor-dependent neuroprotection following neonatal ischemic retinal injury by coordinating redox, mitochondrial, and cell-survival pathways. These results identify Sig1R as a promising therapeutic target for preserving retinal neuronal integrity and long-term visual function in retinopathy of prematurity.",
        "42398881": "ID: 42398881\nTitle: Mitochondrial Dysfunction and Diabetic Retinopathy: Research Progress from Pathogenic Mechanisms to Therapeutic Targets.\nAbstract: Diabetic retinopathy (DR) is one of the most common microvascular complications of diabetes mellitus (DM) and remains a major cause of visual impairment and blindness in adults. Accumulating evidence indicates that DR is not merely a microvascular disorder, but a complex neurovascular disease driven by long-standing hyperglycemia, metabolic dysregulation, oxidative stress, chronic inflammation, neurodegeneration, and impaired neurovascular coupling. Mitochondria are central regulators of cellular energy metabolism and redox homeostasis, and mitochondrial dysfunction is increasingly recognized as a pivotal mechanism linking hyperglycemia-induced metabolic abnormalities to retinal neurovascular unit injury. Under persistent hyperglycemic conditions, excessive glucose flux and metabolic overload promote mitochondrial reactive oxygen species (ROS) overproduction, mitochondrial DNA (mtDNA) damage, impaired oxidative phosphorylation, mitochondrial fusion-fission imbalance, defective mitochondrial biogenesis, dysregulated mitophagy, metabolic reprogramming, and epigenetic alterations. These abnormalities lead to ATP depletion, inflammatory amplification, and activation of multiple forms of programmed cell death, including apoptosis, ferroptosis, pyroptosis, necroptosis, and poly(ADP-ribose) polymerase 1 (PARP1)-dependent cell death. Mitochondrial injury affects retinal endothelial cells, pericytes, Muller cells, microglia, retinal ganglion cells, photoreceptors, and retinal pigment epithelial cells in a cell-type-specific manner, ultimately contributing to blood-retinal barrier disruption, capillary occlusion, neurovascular coupling impairment, retinal neurodegeneration, and progression from non-proliferative to proliferative DR. This review summarizes recent advances in mitochondrial dysfunction in DR, focusing on oxidative stress, mtDNA injury, mitochondrial metabolic reprogramming, mitochondrial dynamics, mitochondrial biogenesis, mitophagy, epigenetic regulation, mitochondria-associated cell death, and neurovascular unit dysfunction. Emerging mitochondria-targeted therapeutic strategies, including mitochondrial antioxidants, modulation of mitochondrial biogenesis and dynamics, mitophagy regulation, mtDNA protection, ferroptosis and inflammasome inhibition, epigenetic intervention, are also discussed. A deeper understanding of mitochondrial mechanisms may provide new therapeutic targets and translational opportunities for DR prevention and treatment.",

To develop and validate a nomogram for individualized risk prediction and stratification of rapidly progressive PDR in T2DM by incorporating diabetes duration, glycated hemoglobin (HbA1c), 24-hour urinary protein quantification, growth differentiation factor 15 (GDF15), Diabetic Retinopathy Severity Scale (DRSS) grade, and foveal avascular zone area. This retrospective study enrolled 342 patients with T2DM (1999 WHO criteria), randomly assigned to training (n=240) and validation (n=102) sets (7:3 ratio). Baseline demographic, clinical, metabolic, renal, inflammatory biomarker, and ophthalmic imaging data were collected. Predictive variables were selected via univariate analysis and least absolute shrinkage and selection operator (LASSO) regression. Independent predictors identified by multivariable logistic regression were incorporated into a nomogram. For comparison, Random Forest, multivariable logistic regression, and Gradient Boosting Machine models were also developed. Model performance was assessed using the area under the receiver operating characteristic curve (AUC-ROC), calibration curves, and decision curve analysis (DCA). Univariate analysis identified six significant factors (all P\u00a0<\u00a00.05): diabetes duration, HbA1c, 24-hour urinary protein quantification, GDF15, DRSS grade, and foveal avascular zone area. LASSO regression retained all six, and multivariable logistic regression confirmed them as independent risk factors for rapidly progressive DR in T2DM (all P\u00a0<\u00a00.05). Three machine learning models were constructed. The Random Forest model achieved the numerically highest validation AUC (0.780) compared with Gradient Boosting Machine (0.741) and multivariable logistic regression (0.698), though the DeLong test showed no statistically significant difference between Random Forest and Gradient Boosting Machine (P\u00a0=\u00a00.38). Calibration curves showed good consistency between predicted and observed probabilities. DCA indicated high clinical net benefit of the model at 0.1-0.8 threshold probability vs other models and extreme strategies. A novel risk prediction model for rapidly progressive PDR in T2DM was developed and validated by integrating multidimensional parameters. Demonstrating favorable discrimination, calibration, and clinical utility, this model provides a promising tool for early identification of high-risk individuals and optimization of personalized intervention strategies.",

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

Prospective observational cohort study. Single-site academic medical hospital. Patients age 60 years and older scheduled for major cardiac surgery with cardiopulmonary bypass (CPB). Delirium assessments were performed at baseline and twice daily up to postoperative day 3. The primary outcome evaluated serum collected before surgery, at the start and end of CPB, and on postoperative day 1. Sixty-five patients were recruited, with 18% of subjects developing postoperative delirium within 3 days of surgery (10 of 57 subjects with complete cognitive assessments). Metabolomic analysis of serum revealed an association between the abundance of cholesterol in large high-density lipoprotein (L-HDL-C%) at the start of CPB and the development of postoperative delirium (odds ratio per standard deviation increment in biomarker concentration, 0.23; 95% confidence interval [CI], 0.08-0.66). Serum neurofilament light chain was inversely correlated with L-HDL-C% levels at the same time point (Spearman \u03c1, -0.39; 95% CI, -0.59 to -0.15) and was significantly higher at the end of CPB in subjects who developed delirium compared to subjects who did not develop delirium (median, 20.4 [interquartile range (IQR),16.1-25.4] pg/mL vs 11.9 [IQR, 7.9-16.9] pg/mL). Circulating blood biomarkers during surgery may provide insight into postoperative cognitive outcomes and should be evaluated in larger cohorts.",

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

Given the increasing interest in retinal imaging as a non-invasive biomarker for neurodegeneration, this study proposes a fully automated machine learning pipeline for disease characterization using optical coherence tomography (OCT). We analyze macular thickness patterns across three key and relevant retinal elements: retinal nerve fibre layer (RNFL), ganglion cell layer to Bruch's membrane (GCL-BM), and the total retina. These are processed by two complementary regional layouts: the standard ETDRS scheme and a custom 3 \u00d7 3 quadrant grid. These measurements are used to train multiple classifiers to distinguish between healthy controls and NDDs either collectively or individually. The proposed method processes 34,375 OCT B-scans from 353 subjects and highlights disease-specific thickness patterns with a pathological distinction score ranging up to 0.71 depending on the retinal region, disease, and classifier. Sector-based grids generally outperform quadrant-based ones, revealing highly localized pathological signatures. Our findings demonstrate that each disease manifests distinct retinal alterations, aligning with current clinical literature while offering novel insights for ET and PD. The study reinforces the potential of grid-based OCT analysis as a discriminative and fully automatic screening tool, paving the way for improved early diagnosis and differential analysis of NDDs through retinal biomarkers.",
        "42415469": "ID: 42415469\nTitle: Proteomic Profile Analysis of Plasma and Aqueous Humor from Glaucoma and Nonglaucomatous Patients.\nAbstract: Glaucoma, a multifactorial ocular neuropathy, can lead to irreversible vision loss. Diagnosis involves assessing optic cupping (increased cup-to-disc ratios) and structural changes (like retinal nerve fiber layer thinning) through clinical imaging. Elevated intraocular pressure (IOP) is commonly associated with glaucoma but is not universally present. However, understanding disease progression is hindered by limited access to donor ocular tissue and consistent clinical data. We hypothesized that the proteomes of aqueous humor (AH) and plasma may be altered in disease and correlate with clinical parameters such as IOP and cup-to-disc ratios. AH and plasma samples were collected from 36 glaucoma patients (17 male, 19 female) and 35 nonglaucomatous control patients (16 male, 19 female) undergoing cataract surgery. Protein profiles was compared using the SOMAscan\u00ae assay system for proteome profiling. From glaucomatous donors, correlations between IOP and cup-to-disc ratios to proteome differences were determined. Overall proteomics profiles between both AH and plasma were compared by combining all samples (glaucoma and nonglaucoma) and then performing correlation analyses. This study revealed similar protein abundance in the two biological fluids. Additionally, it identified different abundance of proteins in plasma and AH between glaucoma and nonglaucoma samples. The differential proteins identified were involved in pathways related to vascular integrity, inflammation, immune response, cell adhesion, and complement activation. Generally, glaucomatous AH showed higher protein levels. Neurofilament light chain protein correlated with elevated IOP and inflammatory markers but not with cup-to-disc ratio. Together, our data demonstrate that the proteins identified in this study from glaucomatous donors correspond to markers of neurodegeneration and those that may inhibit cell proliferation or disrupt vascular integrity.",

Although autophagy dysfunction, glial senescence, and inflammasome activation are well-established contributors to progressive neurodegeneration, these processes are often analysed independently or through pairwise interactions, leaving their collective contribution to persistent neuroinflammation and disease progression insufficiently defined. Here, we synthesise emerging evidence supporting an integrated 'Autophagy-Senescence-Inflammasome (ASI) axis', in which reciprocal interactions among impaired autophagy, senescent glia, and inflammasome signalling establish a self-sustaining cycle of neuroinflammation. We discuss how defective autophagy promotes mitochondrial dysfunction, oxidative stress, and danger signalling, while senescent astrocytes and microglia amplify inflammatory responses through the senescence-associated secretory phenotype (SASP). These intertwined processes converge on chronic inflammasome activation, with mitochondrial dysfunction emerging as a central mechanistic hub. Evidence across Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, stroke, and chronic neuropathic pain highlight the broad relevance of this pathological network. We further analyse current therapeutic strategies targeting autophagy, senescence, and inflammasome pathways, emphasising the limitations of single-target approaches and the potential of multi-target interventions. By integrating these processes into a unified framework, this review provides new insights into the possible molecular mechanisms underlying neuroinflammaging and identifies the 'ASI axis' as a promising target for neurodegenerative disease-modifying therapies.",

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

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

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

Growing evidence implicates ultrafine particles in a wide range of neuropsychiatric conditions, yet their effects remain poorly integrated into clinical and public health frameworks. In this review, we distinguish between size-defined ultrafine particles (UFPs, \u2264100 nm), composition-defined environmental nanoparticles originating from combustion and secondary formation processes, and engineered nanomaterials (ENPs), which differ in physicochemical properties, exposure scenarios, and regulatory status. This narrative systematic review synthesizes findings from human and experimental studies on the neuropsychiatric and neurodevelopmental effects of environmental nanopollutants. A structured search was conducted in PubMed, Web of Science, Scopus, and Google Scholar up to November 2025, following explicit inclusion and exclusion criteria. Eligible studies included peer-reviewed human and animal research assessing mental health or neurological outcomes of nanopollutant exposure. Epidemiological studies\ue5f8primarily involving traffic-related air pollution and mixed combustion-derived ultrafine particle exposures\ue5f8suggest associations with increased risk of cognitive impairment, autism spectrum disorder, depression, schizophrenia, and neurodegenerative diseases, including Alzheimer's, Parkinson's, and amyotrophic lateral sclerosis. Prenatal and early life exposures were linked to cortical thinning, altered neurodevelopmental trajectories, and early proteinopathies. Underlying mechanisms include neuroinflammation, oxidative stress, and protein aggregation. Despite methodological heterogeneity, the evidence supports the urgent need for regulation and prevention. Environmental nanopollutants constitute an under-recognized, modifiable risk factor for neuropsychiatric and neurodegenerative conditions. A paradigm shift is needed to incorporate environmental exposure history into mental health research, risk assessment, and prevention strategies. Regulatory action targeting nanopollutant emission and exposure, particularly in vulnerable populations, is critical to mitigating long-term neurological consequences.",

Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1\u03b1) links metabolic adaptation to stress-response pathways that are repeatedly disrupted in Alzheimer's disease, Parkinson's disease, Huntington's disease, polyglutamine (PolyQ) disorders, and amyotrophic lateral sclerosis. Rather than providing only an updated catalogue of studies, this review organizes the evidence into a cross-disease rheostat framework that explains why PGC-1\u03b1 modulation is protective in some settings but incomplete or maladaptive in others. Current findings indicate that PGC-1\u03b1 supports mitochondrial biogenesis, oxidative phosphorylation, antioxidant defense, mitophagy, autophagy, protein quality control, and inflammatory balance. However, its effects are highly context dependent. In several models, restoration of PGC-1\u03b1-related signaling improves mitochondrial function and reduces neuronal injury, whereas broad, sustained, or cell-inappropriate activation may produce limited benefit or undesirable outcomes. These observations suggest that PGC-1\u03b1 is not a simple neuroprotective switch, but a flexible regulatory hub whose therapeutic value depends on cell type, isoform profile, disease stage, and activation level. Emerging strategies, including small-molecule modulators, gene delivery, antisense-based approaches, nanoparticle systems, and exercise-related interventions, remain largely preclinical and face major barriers related to CNS delivery, pathway selectivity, dose and cell-type control, peripheral safety, and validated target-engagement biomarkers. Nevertheless, clinical translation requires stronger causal validation, reliable target-engagement biomarkers, selective delivery methods, and long-term safety assessment. Future research should focus on precision-based modulation of PGC-1\u03b1 to determine when and how this pathway can be safely used for disease modification. Such a careful approach may help transform PGC-1\u03b1 from a broad experimental target into a clinically relevant strategy for well-defined neurodegenerative phenotypes.",

A bidirectional Mendelian randomization (MR) study.\nAbstract: Neurodegeneration in Alzheimer's disease (AD) is thought to be driven by amyloid-beta and tau deposition in the cerebral vasculature and brain. As the eye is an extension of the central nervous system, this study aimed to determine which neurovascular and neuroretinal changes in the eye are caused by AD rather than associations of the disease. Bidirectional two-sample univariable and multivariable Mendelian randomization (MR) methods were applied. Instrumental variables were derived from genome-wide association studies (GWAS) of AD and the following ocular features: thickness measurements of central macula (MT), retinal nerve fibre layer (mRNFL), ganglion cell-inner plexiform layer (mGCIPL), outer nuclear layer (ONL), inner segment layer (IS), and outer segment (OS) from macular region OCT scans; arteriolar tortuosity (AT), venular tortuosity (VT), venular width (VW), fractal dimension (FD), vertical cup-to-disc ratio (VCDR), optic cup area (OCA), and optic disc area (ODA) derived from other imaging methods. There was strong evidence that genetic liability to AD affected the retinal vasculature by specifically increasing AT (\u03b2 = 0.007;95%CI=0.002,0.011;p-value=0.005) in UK Biobank participants (n=52,798). AD may influence the mRNFL (\u03b2=-0.047,95%CI=-0.119,0.023,p-value=0.18) and mGCIPL (\u03b2=-0.061;95%CI=-0.14,0.025,p-value=0.16) of the inner retina and OS layer (\u03b2 = 0.044;95%CI=-0.0001,0.08;p-value=0.05) but the evidence was weak. Multivariable MR analysis showed that a causal relationship between optic disc area and AD (OR=0.76;95%CI=0.62,0.93,p-value=0.009) was probably mediated by refractive error. Early cerebrovascular signs of AD may be detected by examination of the eye. Further investigation is required to determine the clinical utility of eye screening for dementia.",

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

Although previous studies have identified various risk factors, substantial heterogeneity exists across regions and populations, and most investigations have not comprehensively integrated metabolic markers, microvascular damage, and electrophysiological data. Therefore, a multidimensional assessment of DSPN risk factors is essential to improve early screening and risk-prediction strategies. A total of 120 patients with type 2 diabetes mellitus (T2DM) were enrolled, including 60 with DSPN and 60 without. Compared with the non-DSPN group, patients with DSPN were older, had longer diabetes duration, and demonstrated a higher prevalence of smoking, diabetic retinopathy (DR), and diabetic kidney disease. DSPN patients exhibited poorer glycemic control (higher fasting blood glucose, 2-hour postprandial blood glucose, and hemoglobin A1c [HbA1c]), more pronounced dyslipidemia (elevated triglycerides, reduced high-density lipoprotein cholesterol), and abnormalities in inflammatory and nutritional markers (elevated C-reactive protein and homocysteine [HCY], reduced vitamin B12). Renal function parameters (serum creatinine, estimated glomerular filtration rate, urine albumin-creatinine ratio) indicated more severe microvascular impairment in the DSPN group. Electrophysiological testing showed reduced sensory and motor nerve conduction velocities, decreased amplitudes, and prolonged latencies. Multivariable logistic regression identified diabetes duration, DR, elevated HbA1c, elevated HCY, and reduced sural nerve amplitude as independent risk factors for DSPN. Longer diabetes duration, DR, elevated HbA1c, elevated HCY levels, and reduced sural nerve amplitude were independently associated with DSPN in patients with T2DM. These findings may contribute to improved risk stratification and support further investigation of multidimensional approaches for early DSPN identification. This single-center retrospective cohort study included patients with T2DM treated at our hospital between June 2023 and June 2025. DSPN was diagnosed based on American Diabetes Association, European Federation of Neurological Societies, and diabetic neuropathy working group criteria using a combination of clinical symptoms, neurological signs, and nerve conduction studies. Demographic characteristics, lifestyle factors, diabetes-related complications, glucose and lipid metabolism indicators, renal function, inflammatory and nutritional markers, and electrophysiological parameters were collected. Group differences were assessed using the t-test, Mann-Whitney U test, or \u03c72 test. Variables with P\u2005<\u2005.10 in univariate analyses were entered into multivariable logistic regression to identify independent risk factors for DSPN. Sensitivity analyses and collinearity diagnostics were performed to assess the robustness of the findings.",

Brain targeting depends on a linked sequence: EV ligands and adsorbed protein coronas engage receptor modules, select endocytic routes, determine intracellular fate, and define the therapeutic readouts. These fates include lysosomal degradation, recycling, rare cytosolic delivery, or transport across the blood-brain barrier (BBB). In disease, the same pathways can disseminate proteopathic seeds and amplify neuroinflammation. Heparan sulfate proteoglycans (HSPGs) and LDL receptor family members, including low-density lipoprotein receptor-related protein 1 (LRP1), regulate tau, \u03b1-synuclein, and amyloid-\u03b2 handling. Phosphatidylserine readers and complement shape myeloid sink capture and inflammatory output. Integrin, tetraspanin, and ICAM-1 nanoclusters influence avidity, organotropism, and immune suppression.

Retrospective clinical cohort study using multi-institutional electronic health record data (TriNetX, US Collaborative Network) PARTICIPANTS: : Adults aged \u226518 years with type 2 diabetes mellitus with ophthalmology follow-up. Study cohorts had GABAergic prescription records for 6-months, 1-year, 3-years, or 5-years; control cohorts had no GABAergic prescriptions ever. Cohorts were propensity-score matched (PSM) on demographics, systemic comorbidities, common indications for GABAergic medications, and ophthalmic confounders. Outcomes included incident DR, progression from mild/moderate nonproliferative DR to severe nonproliferative DR, proliferative DR, or interventions required in advanced DR, and incident DR complications. Hazard ratio (HR) and 95% confidence intervals (CI); significance threshold <0.9 or >1.1. After successful PSM, there were 110,495 (6-months), 99,187 (1-year), 63,194 (3-years), and 40,810 (5-years) DR-naive study patients with the respective GABAergic prescription durations of interest. Compared to 109,603 DR-naive control patients, study patients demonstrated a significantly reduced HR for DR development at all time points from 6-months (HR 0.61, 95% CI 0.57-0.65) to 5-years (HR 0.81, 95% CI 0.77-0.85). Study patients (n=14,644) with baseline mild/moderate nonproliferative DR had a significantly reduced hazard of progressing to severe nonproliferative DR, proliferative DR, or DR interventions with 6-months (HR 0.75, 95% CI 0.68-0.82) and 1-year (HR 0.69, 95% CI 0.73, 0.86) GABAergic exposure. Prescription for 6-months (HR 0.74, 95% CI 0.68-0.80) to 3-years (HR 0.80, 95% CI 0.84-0.86) was associated with a significantly reduced hazard for DR complications. Stratification by 4 specific medication indications consistently showed a reduced hazard for DR development with a 6-month prescription duration. GABAergic medication use, particularly short-term exposure, is associated with a reduced hazard of DR development, progression, and complications. These exploratory findings support a potential role of GABAergic modulation in diabetic retinal disease.",

However, there is limited understanding of how HERV-K is trafficked in peripheral biofluids, and the role of exosomes, nano-sized extracellular vesicles, in this process remains largely unexplored. Exosomes offer a stable and cell-specific cargo reservoir that may reflect central pathogenic processes and serve as a minimally invasive biomarker source. In this study, we isolated plasma-derived exosomes from ALS patients (n\u2009=\u200921) and healthy controls (n\u2009=\u200916), and quantified exosomal HERV-K gag, env, and pol transcript levels using SYBR Green qPCR with RNase treatment and normalization to both traditional and exosome-enriched reference genes. HERV-K pol expression was significantly elevated in ALS, with fold-changes ranging from 1.59 to 1.85 (P\u2009=\u20090.037-0.051). env and gag also showed increased expression, though with greater variability. Normalization to the exosome-specific gene SOD2 provided the most consistent signal. These findings suggest that exosomal HERV-K transcripts, particularly pol, could serve as accessible biomarkers for patient stratification and treatment monitoring in HERV-K-targeted ALS trials. This work establishes proof-of-concept for using exosomal cargo to track endogenous retroviral activity in neurodegeneration and supports further investigation of liquid biopsy approaches in ALS precision medicine.",

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

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

Multidomain lifestyle interventions might delay cognitive decline, but populations from Latin America remain under-represented in dementia prevention trials. We aimed to investigate the feasibility of a culturally adapted, multidomain, systematic lifestyle intervention and investigate its effects on global cognitive function in at-risk older adults (aged 60-77 years). The LatAm-FINGERS Initiative for Cognitive Change (hereafter referred to as LatAm-FINGERS) was a single-blind, multicentre, randomised clinical trial conducted in 11 Latin American countries (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Peru, and Uruguay). Individuals aged 60-77 years with high risk of dementia (cardiovascular risk factors, ageing, and dementia risk score \u22656), and suboptimal cognitive performance were randomly assigned (1:1) to receive either a 2-year systematic lifestyle intervention (SLI group) or a flexible lifestyle intervention (FLI group). Randomisation was stratified by the study centre to ensure balance and implemented using permuted blocks of eight. Participants and intervention staff were not masked to group assignment, but individuals who assessed outcomes were masked throughout the trial. The SLI provided structured multidomain lifestyle interventions with supervised support and monitoring; FLI offered health advice. Primary outcomes were trial feasibility (evaluated using selected RE-AIM measures: Reach, Implementation, and Maintenance) and the intervention's effects on global cognitive composite trajectories over 2 years (change in the global cognitive composite score over 2 years). This trial is registered at ClinicalTrials.gov (NCT06492967) and has been completed. Participants were enrolled between Oct 27, 2021, and July 7, 2023; the last participant completed follow-up on Nov 7, 2025. Among 1719 assessed, 1065 participants included in the analytic sample were randomly assigned to the SLI group (n=539) or the FLI group (n=526). Mean age was 67\u00b75 years (SD 4\u00b77), 795 (75%) of 1065 participants were women, and 270 (25%) were men. Self-reported race and ethnicity were: 624 (59%) Mestizo, 288 (27%) White, 72 (7%) Mulatto, 25 (2%) Mixed or other, 18 (2%) Black, 14 (1%) Indigenous, and 24 (2%) did not report race or ethnicity. 877 (82\u00b73%) of 1065 completed the 2-year follow-up. Recruitment effectiveness (Reach) was 62\u00b70%; mean adherence to the SLI group (Implementation) was 71\u00b76% over the entire trial; and frequencies of complete cognitive outcomes data (Maintenance) were 87\u00b79% at 6 months, 85\u00b73% at 12 months, 81\u00b74% at 18 months, and 84\u00b78% at 24 months in the SLI group compared with 86\u00b73% at 6 months, 78\u00b79% at 12 months, 73\u00b74% at 18 months, and 79\u00b78% at 24 months in the FLI group. Dropouts were higher in the FLI group than in the SLI group (20\u00b72% vs 15\u00b72%; p=0\u00b7042). Global cognitive composite scores increased over time in both groups, with a mean annual change of 0\u00b731 SD (95% CI 0\u00b728-0\u00b734) per year in the SLI group and 0\u00b720 SD (0\u00b717-0\u00b723) per year in the FLI group (mean between-group difference of 0\u00b711 SD per year [0\u00b706-0\u00b715; p<0\u00b70001]). Overall, 478 adverse events were reported (412 in the SLI group and 66 in the FLI group). The most common adverse events were musculoskeletal symptoms (113 [21%] in the SLI group, 13 [2%] in the FLI group), upper respiratory infections (50 [9%] in the SLI group, one [<1%] in the FLI group), and COVID-19 infection (31 [6%] events in the SLI group). Serious adverse events occurred in 50 (9%) participants in the SLI group and 24 (5%) participants in the FLI group; none were related to the intervention. There were eight deaths (three in the SLI group and five in the FLI group), and none were related to the intervention. A culturally adapted multidomain lifestyle intervention was feasible across Latin America and resulted in greater cognitive improvements than a flexible health-advice intervention in older adults at risk of cognitive decline. These findings extend the evidence base for multidomain lifestyle interventions to populations historically under-represented in dementia research, supporting their feasibility and scalability as strategies to reduce cognitive decline risk amid the rapidly growing burden of dementia in low-income and middle-income countries.

        "42442908": "ID: 42442908\nTitle: Role of ESCRT pathway and autophagy in neurodegenerative diseases.\nAbstract: Neurodegenerative diseases are characterized by progressive neuronal dysfunction and loss resulting from impaired proteostasis and vesicular trafficking. Neurons are particularly vulnerable to these processes due to their post-mitotic nature and complex architecture. Autophagy and the endolysosomal system constitute the primary degradative pathways responsible for maintaining neuronal homeostasis. However, increasing evidence indicates that their effective function critically depends on coordination with the endosomal sorting complexes required for transport (ESCRT). Beyond their canonical role in multivesicular body biogenesis and membrane scission, ESCRT components are now recognized as essential regulators of autophagosome closure, amphisome formation, autophagosome-lysosome fusion, and endolysosomal membrane repair. Disruption of this ESCRT-autophagy interface has emerged as a common pathological feature across major neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis/frontotemporal dementia. This review synthesizes evidence from genetic, biochemical, and neuropathological studies to highlight shared molecular nodes, such as ESCRT-III components, the VPS4 ATPase, the adaptor protein ALIX, and late endosomal regulators, including Rab7, that couple membrane remodeling to autophagic flux. Failure of these regulatory checkpoints destabilizes endolysosomal integrity, arrests autophagic maturation, and promotes the accumulation of toxic protein species, thereby driving progressive neuronal degeneration. By framing neurodegeneration through the lens of ESCRT-autophagy coupling failure, this review provides a unified mechanistic perspective that links diverse pathogenic proteins to shared cellular vulnerabilities and identifies ESCRT-mediated membrane dynamics as a critical determinant of neuronal survival.",

Translation of therapeutics that have been successful in in vivo models into trials in human patients has proven difficult in recent decades. This failure can be attributed, at least in part, to the lack of specific biomarkers for ALS diagnosis and progression in human ALS patients as well as in in vivo models. Neuromuscular ultrasound is an easily accessible, non-invasive tool to support diagnosis of ALS in humans. Our current study shows for the first time that the disease can be detected in an ALS mouse model with the help of neuromuscular ultrasound. We characterized disease progression regarding changes in the peripheral nerves and muscles of the hind limb in the SOD1G93A mouse model of ALS using different techniques (neuromuscular ultrasound, electroneurography, motor function tests, phenotypic assessments and histology). By neuromuscular ultrasound, we measured the cross-sectional area and diameter of the sciatic nerve and analyzed hind limb muscle texture and thickness. Our results show that motor neuron loss and muscle atrophy - analogous to ALS in humans - can be measured by ultrasound in the SOD1G93A mouse model. Changes in nerve and muscle morphology appear at the same time or even before changes in the established tests (including electroneurographic measurements) performed in vivo in this model. Correlations with histologic features of disease progression make neuromuscular ultrasound a sensitive, non-invasive outcome marker for preclinical studies.",

These diseases share common pathological mechanisms including oxidative stress, mitochondrial impairment, chronic neuroinflammation, protein misfolding, and epigenetic dysregulation. Current therapies offer only symptomatic relief and fail to halt disease progression. Recent advances in transcriptomics and proteomics have enabled the identification of shared molecular pathways and druggable targets across multiple neurodegenerative diseases. The key targets, such as BDNF-TrkB, TREM2, SIRT1, PINK1-Parkin, GSK-3\u03b2, NLRP3, and mTOR have shown promise in preclinical models, offering opportunities for broad-spectrum therapeutic development. Importantly, blood-brain barrier disruption and neuroinflammatory crosstalk exacerbate disease pathology and hinder drug delivery. Innovative strategies involving nanocarriers, gene therapy, and epigenetic modulation are emerging to overcome these barriers. This review highlights the convergence of disease mechanisms, discusses common molecular signatures and therapeutic vulnerabilities, and explores novel small molecular interventions targeting shared pathways mainly in AD and PD. A deeper understanding of aging-associated molecular dysfunction is essential to design sustainable, disease-modifying therapeutics with cross-disease relevance.",

We retrospectively analyzed 11 eyes that received intra-vitreal anti-VEGF injections for treatment-na\u00efve mCNV. Based on treatment response during the first 3 months, eyes were categorized into the single-injection (n\u2009=\u20099) and multiple-injection (n\u2009=\u20092) groups. PS-OCT en face PE maps (6\u2009\u00d7\u20096\u00a0mm) were obtained at baseline and 3 months after treatment, with the analysis area manually centered over the CNV using a 3-mm Early Treatment Diabetic Retinopathy Study (ETDRS) grid. PE values were extracted from the central 1-mm circle (CNV core) and surrounding 1-3-mm annulus (periphery), and the differences before and after treatment were calculated. Intergroup comparisons were conducted using Wilcoxon rank-sum test. PE within the CNV core increased after treatment (p\u2009=\u20090.0037). The multiple-injection group showed a greater PE increase than the single-injection group (p\u2009=\u20090.0347), although this finding should be interpreted cautiously given the small and imbalanced sample size. Exploratory analysis suggested a positive association between the magnitude of PE change in the CNV core and injection number during the 3-month period. High post-treatment entropy may reflect structural heterogeneity associated with pigment epithelial remodeling during the early healing phase. These findings suggest that PS-OCT entropy imaging may serve as a retrospective indicator of tissue response rather than a predictive biomarker in the present dataset. Given the very small and imbalanced sample size, the results should be interpreted as exploratory and hypothesis-generating.",

The ubiquitin-proteasome system (UPS), a major pathway for selective intracellular protein degradation, is essential for maintaining neuronal protein homeostasis. Proteasome dysfunction has been implicated in several major neurodegenerative disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and Huntington's disease (HD), although its extent and mechanisms vary across disease contexts. In this review, we examine current evidence for proteasome dysfunction in neurodegeneration and discuss how disease-associated proteins impair proteasome function through direct inhibition, defective substrate processing, and sequestration into protein aggregates. We also address the contribution of oxidative stress, neuroinflammation, and aging to proteasome dysregulation. Finally, we highlight emerging therapeutic strategies aimed at restoring proteasome function, including pharmacological activation, modulation of proteasome assembly and stability, and targeted protein degradation approaches. Understanding the context-dependent nature of proteasome dysfunction will be important for developing effective proteostasis-based therapies.",

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

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

Exosomes have emerged as key mediators of central nervous system communication and are increasingly central to the biology of neurodegeneration. These nanoscale vesicles transport proteins, lipids, and nucleic acids across cellular and anatomical barriers, influencing synaptic function, immune signaling, and metabolic homeostasis. Under pathological conditions, exosomes facilitate the spread of misfolded proteins such as amyloid-\u03b2, p-tau, \u03b1-synuclein, and TDP-43, thereby accelerating network-level degeneration. At the same time, their cargo exhibits disease-specific molecular signatures detectable in peripheral biofluids, supporting their development as minimally invasive biomarkers for early diagnosis and longitudinal monitoring. Advances in exosome engineering further underscore their potential as therapeutic delivery vehicles capable of crossing the blood-brain barrier and targeting pathogenic pathways with RNA-based therapeutics, proteins, or gene-editing systems.

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

The system composed of the urokinase-type plasminogen activator (uPA) and its receptor (uPAR) has previously emerged as a potential regulator of the pro-inflammatory events in DR, possibly through the interaction of uPAR with its lateral partners, such as formyl peptide receptors (FPRs). This study explored whether the inhibition of uPAR/FPR1 crosstalk may reduce early neurovascular alterations in DR by targeting inflammation. To this aim, the new FPR1 antagonist N-19004 was tested in a rat model of streptozotocin-induced diabetes. N-19004 was administered subcutaneously for 7\u202fdays at 1\u202fmonth from diabetes onset. Immunofluorescence, RT-qPCR, Western blot and Evans blue perfusion were performed to evaluate the effects of N-19004 on inflammation, reactive gliosis, blood-retinal barrier (BRB) integrity and apoptosis. In addition, electroretinogram (ERG) was used to assess N-19004 efficacy on retinal function. N-19004 inhibited the activation of inflammation-related transcription factors, including nuclear factor kappa-light-chain-enhancer of activated B cells and signal transducer and activator of transcription 3, leading to reduced interleukin-1\u03b2 and tumor necrosis factor-\u03b1 expression. The attenuation of inflammatory processes resulted in reduced glial activation, as indicated by lower glial fibrillary acidic protein expression and M\u00fcller cell gliosis. The anti-inflammatory activity of N-19004 was accompanied by decreased BRB breakdown, as demonstrated by N-19004-mediated reduction of vascular endothelial growth factor, increased levels of tight junction components and diminished vessel leakage. The amelioration of BRB integrity was associated with reduced activation of caspase 3 and partial preservation of scotopic ERG a- and b-wave amplitudes, thereby improving retinal viability and function in N-19004-treated STZ rats. These results support the possible involvement of uPAR/FPR1 interactions in the regulation of DR-related inflammation and suggest a novel therapeutic target for the management of the early phases of disease.",

Imaging biomarkers have emerged as important tools for improving the diagnosis, monitoring, and biological characterization of neurodegenerative diseases. Structural MRI, diffusion tensor imaging (DTI), functional MRI (fMRI), positron emission tomography (PET), hybrid PET/MRI and molecular imaging have transformed our ability to investigate neurodegeneration in vivo non-invasively.

According to the PICOS principle, relevant studies were searched in the following databases: PubMed, Web of Science, Embase, Cochrane Library, Scopus, and CNKI. Search terms and strategies were determined based on MeSH terms. The methodological quality of the included studies was assessed using the SYRCLE's Risk of Bias tool and the CAMARADES checklist. Meta-analysis was performed using Stata 15.0 and Rstudio software. Seventeen studies involving 372 animals were included. The quality scores of the included studies ranged from 5 to 8, with an average score of 7. The meta-analysis of the primary outcome, the rotarod test score, showed a significant improvement in the EA group compared to the control group [SMD\u202f=\u202f3.31, 95% CI (2.05, 4.57), Z\u202f=\u202f5.151, p\u202f<\u202f0.001], indicating that EA can enhance motor function in ALS mice. Regarding secondary outcomes, EA intervention alleviated neuroinflammation, promoted neuronal survival, improved axonal regeneration inhibition, and stabilized RNA metabolism homeostasis. Consequently, it slowed disease progression, improved motor performance, prolonged survival time, and effectively protected motor neurons at the histopathological level (p\u202f<\u202f0.05). These findings underscore the potential of EA as a promising multimodal therapeutic strategy for ALS. For the heterogeneity observed in the rotarod test, sensitivity analysis, subgroup analysis, and meta-regression did not identify its source. However, potential publication bias was detected, which might contribute to the heterogeneity. The heterogeneity for other outcome measures might originate from differences in stimulation parameters (e.g., waveform), acupoint selection, or treatment duration. This meta-analysis demonstrates that EA confers significant neuroprotective benefits in preclinical ALS models, primarily through multi-target modulation of key pathological processes such as neuroinflammation, aberrant cell death signaling, and RNA metabolism. These preclinical findings underscore the potential of electroacupuncture as a complementary neuroprotective strategy and warrant further investigation in rigorous clinical trials. https://www.crd.york.ac.uk/PROSPERO/view/CRD420251229183.",

We aimed to assess the independent association between a deep learning (DL)-derived retinal biomarker using coronary artery calcification (Dr. Noon CVD) and DF-related amputation in patients with type 2 diabetes. This retrospective observational study conducted in a university hospital in South Korea included 392 individuals with type 2 diabetes receiving ophthalmic care (79 with DF-related amputation and 313 without). Participants were randomly split into training (70%) and validation (30%) sets. Model performance in relation to DF-related amputation was assessed using area under the receiver operating characteristic curve (AUC), continuous net reclassification index (cNRI), and integrated discrimination improvement (IDI). Prespecified rule-out (sensitivity \u22650.85) and rule-in (specificity \u22650.90) thresholds were also applied. Adding the retinal biomarker to a basic clinical model showed incremental association with DF-related amputation in the validation set (AUC 0.146, 95% CI: 0.046-0.249; cNRI 0.629, 95% CI: 0.184-1.027; IDI 0.062, 95% CI: 0.012-0.110). The full model achieved an AUC of 0.791, and the association remained consistent across sensitivity analyses using DF risk score derived from the external dataset. Under a 27% amputation prevalence (based on the reported prevalence of amputation among patients with diabetic foot), sensitivity was 87.5% with a negative predictive value of 92.6% at the rule-out cutoff; specificity was 90.4% with a positive predictive value of 56.3% at the rule-in cutoff. A DL-derived retinal biomarker shows meaningful association with DF-related amputation beyond conventional diabetes variables.",

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

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

However, the limited availability and volumes of CSF samples restrict the broader clinical application of CSF-based biomarker panels. To address this challenge, we investigated whether the novel nucleic acid-linked immuno-sandwich assay (NULISA) multiplex platform-capable of quantifying multiple neural, glial, and inflammatory markers from minimal biofluid volumes-could validate previously proposed biomarkers and identify additional candidates relevant to ALS. Using this platform, we measured a targeted panel of 131 biomarkers in cohorts of patients with C9orf72-associated ALS, sporadic ALS (sALS), and matched healthy controls. The 6 markers neurofilament heavy chain (NEFH) and neurofilament light chain (NEFL), chitinases-particularly chitotriosidase-1 (CHIT1) and chitinase-3-like protein-1 (CHI3L1), and chemokines CCL2 and CCL3 were significantly elevated in both ALS groups compared with controls. These biomarkers correlated with disease progression and demonstrated strong diagnostic performance when combined into aggregate scores, as reflected by a high area under the receiver operating characteristic curve for ALS. Notably, C9orf72-ALS patients exhibited higher levels of the oxidative stress-related markers PRDX6 and ENO2, compared with sALS patients, suggesting a genotype-specific molecular signature. Overall, our findings support the use of a multiplexed panel of diverse, inflammatory, glial, and neurodegeneration-associated biomarkers as a complementary diagnostic and prognostic tool alongside established measurements of neurofilaments. This approach may enhance biomarker robustness while minimizing CSF volume requirements, thereby improving clinical feasibility in ALS research and care.",

Regulatory T cells (Tregs) exert potent immunosuppressive and neuroprotective effects, offering great potential for ALS treatment. However, clinical application of Treg therapy is hampered by low peripheral cell abundance and unstable expansion quality. Here, we established and optimized a GMP-grade protocol for sorting and expanding peripheral blood-derived Tregs, and validated cryopreserved apheresis products as feasikble starting materials. Although ALS patient-derived Tregs showed reduced expansion capacity compared with healthy donor counterparts, they maintained comparable purity, stable regulatory phenotypes, and robust immunosuppressive function. Transcriptomic analysis confirmed the lineage fidelity and low pro-inflammatory characteristics of expanded Tregs. Therapeutic efficacy was verified in SOD1G93A ALS and GvHD mouse models with delayed disease progression and relieved inflammation. This study provides standardized GMP manufacturing strategies and solid preclinical evidence to support the ongoing clinical trial (NCT06671236) and facilitate Treg immunotherapy translation for ALS.",

This narrative review investigates the effect of common herbal medicines and functional foods in oxidative stress, based on available experimental and clinical data. Curcuma longa, Emblica officinalis, Zingiber officinale, berries, and leafy vegetables, which contain bioactive molecules like polyphenols, flavonoids, and terpenoids, have been shown to have antioxidant and anti-inflammatory properties through activation of Nrf2 and NF-\u03baB signalling pathways. The important findings from this review suggest that curcumin and gingerol possess anticancer properties via the regulation of p53, MAPK, and ROS-JNK pathways, which induce apoptosis in cancer cells. Moreover, these bioactive compounds improve mitochondrial dysfunction and redox status in cardiovascular diseases. Bacosides and withanolides can be used for neuroprotection by preventing oxidative injury and protein aggregation in neurodegenerative diseases. The antioxidant-rich herbs and functional foods may have promising roles in oxidative stress-related disorders as preventative and supportive treatment options; however, further research is needed to establish their efficacy and safety in patients.",

Resveratrol, a polyphenolic phytoalexin mainly found in grapes and red wine, is a promising treatment candidate due to its diverse biological effects and neuroprotective properties. This review demonstrates the regulatory effects of resveratrol on cellular signaling pathways linked to NDs and its neuroprotective mechanisms. Resveratrol enhances neuronal survival, boosts mitochondrial biogenesis, and mitigates oxidative stress by affecting key molecular pathways, including SIRT1/AMPK, PI3K/Akt, MAPK, and Nrf2/ARE. The PI3K/Akt and ERK1/2 pathways promote neuronal regeneration by modulating pro-apoptotic and anti-apoptotic factors. Resveratrol inhibits NF-\u03baB, reducing cytokine release and microglial activation, thereby exhibiting anti-inflammatory properties. It improves cognitive function, synaptic plasticity, and neuronal survival. Despite an increasing pharmacological profile, its practical applicability is limited by inadequate bioavailability, rapid metabolism, and restricted brain penetration. This review demonstrates resveratrol's effect on interconnected signaling networks related to neurodegeneration. We critically compare evidence from preclinical and clinical studies, demonstrating both therapeutic potential and translational limitations. Emerging nanotechnology-based delivery strategies are demonstrated to overcome bioavailability and blood-brain barrier penetration challenges. These insights provide a translational perspective for the future development of resveratrol-based interventions in NDs.",

Optical coherence tomography (OCT) provides noninvasive quantification of retinal layer damage, offering potential for NMOSD diagnosis and differentiation from MS. Fifty-five articles were included in this meta-analysis. All patients underwent OCT examination, with at least one measurement recorded for retinal assessment. This review is reported according to the Meta-analysis of Observational Studies in Epidemiology guidelines and assessed the risk of bias of the included studies. Subgroup analysis assessed the clinical utility of OCT biomarkers across predefined subgroups. Sensitivity analysis was used to evaluate stability of results. Begg's and Egger's test and funnel plot were applied to assess publication bias. The results showed that the thickness of peripapillary retinal nerve fiber layer (pRNFL) (WMD\u202f=\u202f-17.73, p\u202f<\u202f0.001), macular RNFL (WMD\u202f=\u202f-5.35, p\u202f<\u202f0.001), superior RNFL (RNFL-S) (WMD\u202f=\u202f-32.91, p\u202f<\u202f0.001), inferior RNFL (RNFL-I) (WMD\u202f=\u202f-39.21, p\u202f<\u202f0.001), temporal RNFL (RNFL-T) (WMD\u202f=\u202f-17.74, p\u202f<\u202f0.001), nasal RNFL (RNFL-N) (WMD\u202f=\u202f-13.59, p\u202f<\u202f0.001), superotemporal RNFL (WMD\u202f=\u202f-25.60, p\u202f<\u202f0.001), inferotemporal RNFL (WMD\u202f=\u202f-26.97, p\u202f=\u202f0.001), superonasal RNFL (WMD\u202f=\u202f-19.84, p\u202f<\u202f0.001), inferonasal RNFL (WMD\u202f=\u202f-23.31, p\u202f<\u202f0.001), ganglion cell and inner plexiform layer (GCIPL) (WMD\u202f=\u202f-14.03, p\u202f<\u202f0.001), ganglion cell layer (WMD\u202f=\u202f-9.34, p\u202f<\u202f0.001), inner plexiform layer (WMD\u202f=\u202f-6.02, p\u202f<\u202f0.001), outer nuclear layer (WMD\u202f=\u202f-2.03, p\u202f<\u202f0.001), foveal (WMD\u202f=\u202f-12.95, p\u202f<\u202f0.001) and GCIPL volume (WMD\u202f=\u202f-0.11, p\u202f<\u202f0.001) in NMOSD were significantly thinner than those in the normal population, but no significant changes were found in the outer plexiform layer and photorreceptor layer. On the other hand, compared with MS, NMOSD had significantly thinner pRNFL (WMD\u202f=\u202f-11.68, p\u202f<\u202f0.001), RNFL-S (WMD\u202f=\u202f-18.09, p\u202f=\u202f0.017) /RNFL-I (WMD\u202f=\u202f-21.25, p\u202f=\u202f0.008)/ RNFL-T (WMD\u202f=\u202f-6.47, p\u202f<\u202f0.001)/RNFL-N (WMD\u202f=\u202f-2.38, p\u202f=\u202f0.048) and GCIPL (WMD\u202f=\u202f-4.22, p\u202f<\u202f0.001).

While Secretory leukocyte protease inhibitor (SLPI) is known for its immunomodulatory properties, its specific role in ALS pathogenesis has not been fully established. This study aimed to characterize the expression patterns and functional significance of SLPI in ALS models. The study utilized SOD1G93A mice to analyze the spatiotemporal dynamics of SLPI expression in the gastrocnemius muscle, lumbar spinal cord, and serum across different disease stages. In vitro functional assays were conducted using siRNA-mediated knockdown of SLPI in BV2 (microglia), MA (astrocytes), and NSC-34 (motor neurons) cell lines. Additionally, recombinant SLPI protein was applied to LPS-stimulated BV2 cells to investigate its effect on the TLR4/ NF-\u03baB signaling pathway. In SOD1G93A mice, SLPI was significantly upregulated in the gastrocnemius muscle from the pre-symptomatic stage (60 days) through the late stage (130 days). In the lumbar spinal cord, SLPI showed a transient initial increase but declined sharply by the end-stage; a similar significant reduction was observed in late-stage serum levels. In vitro, SLPI knockdown exacerbated pro-inflammatory cytokine production in all three cell types and impaired the antioxidant capacity of NSC-34 motor neurons. Mechanistically, recombinant SLPI attenuated inflammation in BV2 cells by modulating the TLR4/NF-\u03baB pathway. The dynamic changes in SLPI levels suggest its potential relevance as a candidate molecule for disease staging. Meanwhile, its protective effects in regulating inflammation suggest that it could be a promising therapeutic candidate for mitigating ALS-associated neuroinflammation.",

Its pathological mechanism is complex, involving the regulation of multiple processes such as abnormal neovascularization, nerve damage, oxidative stress, and chronic inflammation. As a key molecular mechanism for regulating protein function, post-translational modifications (PTMs) can dynamically modulate the activity and function of core cells (including retinal endothelial cells, M\u00fcller cells, and pericytes) and related signaling molecules including various forms (e.g., phosphorylation, glycosylation, acetylation, methylation, ubiquitination, and SUMOylation), thereby deeply participating in the pathological progression of DR. In addition, PTMs play a crucial role in the regulating signaling pathways, including PI3K/Akt, MAPK, AMPK, NF-\u03baB and JAK/STAT, in the development of DR. Moreover, increasing evidence demonstrates that targeting PTMs with small molecules, either as inhibitors or activators, can reverse protein misfolding and preserve neuroretinal integrity to halt the progression of DR. This review systematically summarizes the variation characteristics of different types of PTMs in DR, analyzes the involvement of PTMs on signaling cascade and cellular processes, reviews the association between ageing and PTMs, and sorts out the research progress of PTMs as potential diagnostic biomarkers and neuroprotective therapeutic targets for DR.

Our previous study found that Ginger-Coptis formula, a traditional Chinese medicine (TCM) formula, significantly ameliorated diabetic retinopathy, and 6-shogaol was identified as one of the possible contributive compounds. This study aims to investigate the pharmacological effects of 6-shogaol, a key bioactive compound in ginger (Zingiber officinal Roscoe), as a novel inhibitor for myoferlin (MYOF). It also proposes to demonstrate the regulatory effects of 6-shogaol on vascular endothelial growth factor receptor 2 (VEGFR2)/ protein kinase B (Akt)/endothelial nitric oxide synthase (eNOS) signaling in hyperglycemia-induced retinal vasculature as potential molecular mechanisms. The stable isotope labeling by amino acids in cell culture (SILAC) was used to identify the direct binding protein by 6-shogaol under high glucose. The inhibitory activity of 6-shogaol on MYOF was evaluated by cellular assays. Both in vitro assays and streptozotocin-induced diabetic mouse models were used to investigate the effects of 6-shogaol. A structure-activity relationship was conducted to explore the structural basis of 6-shogaol that may contribute to the inhibition of targeted protein function and the angiogenic response to high glucose. The mechanisms were further confirmed by overexpression of targeted proteins in vivo. 6-Shogaol potentially targeted MYOF in retinal endothelial cells and inhibited its function on the regulating the stability and activity of VEGFR2, which reduced the angiogenic responses in the retinal endothelial cells under high glucose. The potential mechanism involved the downregulation of VEGFR2/Akt/eNOS pathway. These effects of 6-shogaol might be associated with structural features such as its \u03b1,\u03b2-unsaturated ketone moiety. 6-Shogaol had the therapeutic potential of alleviating the retinal vascular dysfunction in diabetic mice.

Dysfunction of the retinal pigment epithelium (RPE) is an early pathogenic event, where various mechanisms may contribute to the disease progression. circular RNAs (circRNAs) have been reported to be important regulators in diabetic complications, acting as miRNA sponge, participating in the regulation of gene transcription or coding short peptides. Circular RNA microarray and RNA-seq were used to identify differentially expressed circRNAs in ARPE-19 cells in normal and high glucose treatments. The expression of cKIAA1462, miR-183-5p, and high mobility group box 1 (HMGB1) were determined using quantitative real-time polymerase chain reaction and Western blot. In vitro experiments, such as flow cytometry, Western blot, and Electron microscope (TEM) were conducted. The binding interaction was confirmed using dual-luciferase reporter and overexpression/inhibition experiments. cKIAA1462 was knocked down via intravitreal lentiviral injection in diabetic mice, followed by expression level detection, functional analysis and histological assessments. cKIAA1462 was significantly upregulated under high glucose conditions both in vitro and in vivo (in retinas of diabetic mice). It acted as a molecular sponge for miR-183-5p, increasing the expression of HMGB1. Elevated HMGB1 concurrently impaired autophagic flux (increased p62, decreased autophagosomes) and activated the NLRP3 inflammasome (upregulated NLRP3, ASC, caspase-1), promoting pyroptosis. Silencing cKIAA1462 in vivo restored autophagy, suppressed pyroptosis, improved retinal structure, and enhanced electroretinogram responses in diabetic mice. The cKIAA1462/miR-183-5p/HMGB1 axis plays a critical role in diabetic RPE injury by dual regulation of autophagy and pyroptosis.

Mid-diaphyseal origin and multilobed morphology are exceptionally uncommon and may present diagnostic and surgical challenges. We report a rare case of a solitary, multilobed osteochondroma arising from the posterior humeral midshaft in an 18-year-old male. The patient presented with a 1-year history of a gradually enlarging, painless mass over the lateral aspect of the left upper arm, without functional limitation or neurovascular symptoms. Physical examination revealed a firm, immobile, nontender mass with intact distal neurovascular status. Magnetic resonance imaging demonstrated a pedunculated osseous lesion measuring 6.5 \u00d7 3.3 \u00d7 2.3\u2009cm, exhibiting continuity with the humeral medullary cavity and a distinctive three-lobed configuration, including a bilobed stalk. The cartilage cap thickness measured approximately 4\u2009mm, with no surrounding soft tissue abnormalities. Surgical excision was performed via a posterior longitudinal approach, with careful identification and preservation of the radial nerve. Intraoperatively, three distinct pedunculated bony stalks arising from the posterior humeral midshaft were excised en bloc. Histopathological analysis confirmed a benign osteochondroma, showing mature trabecular bone capped by hyaline cartilage without atypia or malignant features. To the best of our knowledge, no previous report has specifically described this combination of posterior humeral mid-diaphyseal location and multilobed morphology. This case expands the anatomical and morphological spectrum of osteochondroma and highlights the critical role of advanced imaging in preoperative planning, particularly for lesions in proximity to major neurovascular structures.

This is a cross-sectional study. Using systematic random sampling, 385 displaced adults living with diabetes, aged 19 years or older, were recruited. The study was conducted at the diabetes center in Port Sudan from October 2024 to May 2025. Data on sociodemographic characteristics, clinical history, and barriers to care were collected through structured questionnaires. Bivariate analyses and binary logistic regression were used to identify factors associated with uncontrolled diabetes. Participants had a mean age of 53\u2009\u00b1\u200912 years; 51.4% were female. All were displaced because of the armed conflict. The mean HbA1c was 9.38% (\u00b1\u20092.42); only 16.6% of participants achieved glycemic control (HbA1c\u2009<\u20097.0%). Poor adherence to diabetes management was reported by 15.8% of patients, with an average HbA1c of 12.09% in this group.

In regression analysis, poor adherence was the sole factor significantly associated with uncontrolled diabetes (OR 41.96, 95% CI [11.04, 159.52], p\u2009<\u20090.001). Female gender and higher education were associated with higher mean HbA1c in bivariate analysis (9.63% vs. 9.11%, p\u2009=\u20090.015; p\u2009=\u20090.007, respectively) but were not independent predictors in the multivariate model. Stress exposure was nearly universal (99.2%) but not significantly associated with glycemic control in this sample. In this cross-sectional study of displaced PWD, the context of armed conflict in Sudan was associated with a high prevalence of poor glycemic control; diabetic foot syndrome was present in 26.5% and retinopathy in 20.8% of participants; as these were self-reported and patient overlap was not assessed, these figures represent individual prevalences rather than cumulative burden. Adherence to management was the key modifiable factor correlated with glycemic outcomes. These findings highlight an urgent need for conflict-sensitive diabetes management strategies. Humanitarian responses should consider ensuring reliable, affordable access to care and support programs as a potential means to address the cascade of diabetes-related complications in conflict settings.

Characterizing TpES-evoked visual cortical responses is critical to expand the clinical application of minimally invasive neuromodulation. We performed intrinsic optical signal imaging in the cat visual cortex to characterize spatiotemporal neurovascular coupling responses to independent-channel TpES, analyzed retinal electric field distribution via a human head computational model, with TcES as a control in both in vivo and simulation experiments. TpES evoked peripheral visual field cortical responses and retinal electric fields consistent with TcES patterns, with similar temporal dynamics. TpES amplitudes were comparable or significantly higher, indicating more efficient visual pathway activation. Our findings provide important evidence supporting the advancement and optimization of non-invasive stimulation techniques for the treatment of retinal neurodegenerative diseases.",

On presentation, he was intoxicated and hemodynamically unstable, requiring immediate management according to Advanced Trauma Life Support principles. Initial management included prompt resuscitation followed by urgent irrigation and debridement of the open fracture. Definitive fixation was performed in a staged manner after physiological optimization. The proximal humeral fracture was managed with dual plating and calcar support to restore stability and alignment, while the comminuted olecranon fracture required a multimodal fixation approach incorporating plates, cerclage wiring, and screw fixation to achieve stable reconstruction. Despite the severity of injury and initial physiological compromise, the patient achieved a favorable outcome with preserved neurovascular function and early return of joint mobility. At the six-month follow-up, there was satisfactory functional recovery of both the shoulder and elbow. This case is notable for the rare combination of injuries and highlights the importance of systematic trauma management, careful operative planning,\u00a0and a multidisciplinary approach to rehabilitation. It also underscores the ethical considerations involved in urgent decision-making when treating an intoxicated patient who lacks capacity.",

This prospective cohort study enrolled 235 premature infants with ROP (diagnosed January 2024-May 2025) and 110 gestational-age-matched controls. ROP infants were stratified into poor-outcome (n\u2009=\u200934) and favorable-outcome (n\u2009=\u2009201) subgroups based on treatment response and longitudinal neurovascular findings. Poor outcome was defined as posterior pole retinal fold involving the macula, retinal detachment, or posterior pole obscuration by fibrous tissue or a \"white mass\" at \u22656\u2009months after intravitreal anti-VEGF therapy. Tear fluid and venous blood were collected within 24\u2009h of the first ROP diagnosis; CHI3L1 and PTX3 were measured by enzyme-linked immunosorbent assay. Spearman correlation, multivariable logistic regression, and receiver operating characteristic (ROC) curves were employed to examine the associations. Tear and serum CHI3L1 and PTX3 concentrations increased stepwise across control, mild-ROP, and severe-ROP groups (all p\u2009<\u20090.05), correlating positively with fundus stage (Spearman r\u2009=\u20090.610-0.779). Infants with unfavorable neurovascular outcomes had higher baseline levels than those with favorable outcomes (p\u2009<\u20090.05). Multivariable analysis identified gestational age, birth weight, severe ROP, bronchopulmonary dysplasia, tear CHI3L1, tear PTX3, serum CHI3L1, and serum PTX3 as independent predictors of poor outcome (p\u2009<\u20090.05). The four-biomarker panel predicted progression with an area under the curve of 0.847 (95% CI 0.775-0.919), outperforming individual markers (p\u2009<\u20090.05).

Several antidepressants have been observed to reduce REM sleep fraction on polysomnography. We investigated whether prescription of REM-suppressing antidepressants (RSAs) versus non-REM-suppressing antidepressants (NRSAs) is associated with differential survival in patients with amyotrophic lateral sclerosis (ALS). Using the U.S. Collaborative Network of the TriNetX Analytics platform, we compared 1-year mortality in ALS patients prescribed RSAs or NRSAs within 3 months of diagnosis, identified by ICD-10-CM-coded encounter diagnoses with riluzole prescription between May 2014 and May 2024. We used Cox proportional hazards models, Kaplan-Meier analysis, and risk difference analysis, with and without propensity score matching (PSM). Among 14,441 patients with ALS and riluzole prescription, 5,057 were prescribed either RSAs (N = 4,177) or NRSAs (N = 880). The NRSA cohort had a higher risk of death (HR 1.28, 95% CI 1.11 - 1.46), with 1-year survival of 60.73% versus 68.61% for RSAs (log-rank p<0.001). After PSM, the difference narrowed and was borderline by log-rank test (60.97% vs 65.92%, p=0.035), while the risk-difference analysis was no longer significant (RR 1.07, 95% CI 0.92 - 1.25), indicating an attenuated and statistically fragile association. RSA prescription was associated with modestly better survival, but this association weakened markedly after matching and cannot establish causation; residual confounding, particularly by indication, cannot be excluded. These findings are hypothesis-generating, and prospective studies incorporating polysomnography and ALS-specific prognostic factors are needed.",

However, the impact of the APOE \u025b4 allele on the accumulation of AD-related neuropathology in patients with T2DM remains unclear. We analyzed amyloid beta (A\u03b2) and tau deposition patterns via positron emission tomography (PET) imaging in 163 T2DM patients (64 \u025b4 carriers) and 1654 normal glucose metabolism subjects (687 \u025b4 carriers). Findings reveal that A\u03b2 deposition has a broader range of influence in diabetics carrying the \u025b4 allele, especially in the deep cortical areas. In terms of tau accumulation, diabetic carriers exhibit progression to the posterior and frontal cortices. Specifically, a greater A\u03b2 PET burden is associated with higher levels of plasma A\u03b242 and lower levels of cerebrospinal fluid (CSF) A\u03b242, A\u03b242/40, and A\u03b242/38. A significant positive correlation was observed between tau PET burden and CSF tau and phosphorylated tau (pTau), and plasma pTau181. Importantly, higher A\u03b2 and tau standardized uptake value ratio were associated with poorer memory performance and lower scores on the Montreal Cognitive Assessment. These findings highlight the allele's region-specific synergism with T2DM in driving AD-related pathology, potentially informing the development of a neuroimaging-based grading system to evaluate diabetic neuropathology severity and progression dynamics.",

This review summarizes brain parenchymal and neurovascular imaging modalities for the evaluation of suspected PCS in the emergency department (ED). We conducted a structured narrative review of established and emerging modalities, describing each modality's technical principles, clinical roles, performance estimates, evidence base, limitations, and real-world application. Searches emphasized ED populations and posterior fossa infarction; society guidelines and meta-analyses were prioritized. Non-contrast CT is insensitive for acute PCS (reported 16-44%) but remains essential for excluding hemorrhage. CT angiography is roughly 80% sensitive for vertebrobasilar occlusion in selected cohorts and\u2009~\u200944% sensitive for PCS overall. CT perfusion adds incremental sensitivity (around 70-75%). MRI with diffusion-weighted imaging is\u2009~\u200980% sensitive in pooled estimates; high-resolution DWI may approach 90-95% in single-center series. Emerging modalities - dual-energy CT (41-88% sensitive), portable low-field MRI (estimated 69% sensitive), and accelerated or abbreviated MRI (likely 80-95% sensitive) - are at varying stages of adoption. Performance metrics of emerging modalities derive from small, single-center cohorts with probable spectrum bias.

A longer isoform, \"big tau,\" produced by inclusion of exon 4a, is expressed in the peripheral nervous system (PNS) and central nervous system (CNS) regions. We sought to characterize big tau composition, anatomic distribution, and disease relevance. Mass spectrometry (MS) was used to sequence big tau and map its distribution across the human nervous system. Postmortem samples included brain tissue from Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), and controls; spinal cord and peripheral nerves. Big and canonical (\"small\") tau isoforms were also quantified in cerebrospinal fluid (CSF) from controls and participants stratified by amyloid status and cognitive impairment. Human big tau results from insertion of either 355 or 251 amino acids encoded by exon 4a-long and exon 4a-short, respectively. Alternative splicing of exons 2, 3, and 10 generates multiple big tau isoforms. Total tau levels were approximately 1,000-fold higher in the brain than in the PNS; however, the relative abundance of big tau increased from the CNS to the PNS, comprising 50% of the total tau in the periphery and approximately 1% in the brain, primarily localized to the cerebellum. In CSF, big tau levels were unchanged by amyloid abnormalities or cognitive impairment, whereas canonical tau increased with AD pathology. Big tau represents a distinct tau population enriched in the PNS and uncoupled from disease-associated changes in brain-derived tau, suggesting that distinguishing big tau from canonical tau may improve interpretation of tau biomarkers and help differentiate CNS neurodegeneration from peripheral nerve pathology.

MicroRNAs (miRNAs) are short, single-stranded, non-coding ribonucleic acid (RNA) molecules, 18 to 24 nucleotides long. They play a role in posttranscriptional gene regulation by binding to complementary sequences on messenger RNA (mRNA), thereby promoting mRNA degradation or preventing translation into protein. MiRNAs are essential regulators of the genome because they bind targets and alter gene expression. MiRNA biogenesis and functions are tightly regulated, and their dysregulation is associated with various diseases, including cancer, cardiovascular diseases, and neurodegenerative disorders. In particular, disruption of the Blood-Brain Barrier in neurodegenerative diseases allows molecules to leak into the bloodstream, enabling the detection of miRNAs in other body fluids and making these fluids potential biomarker sources. In this context, miRNAs can be measured in blood, cerebrospinal fluid, and other biological samples. It has significant potential for early diagnosis, disease progression monitoring, and evaluation of treatment efficacy. In this review, the relationship between MiRNAs and neuronal degeneration diseases was evaluated. In this review, prepared in light of the current literature scanned through the PubMed database, we examined data from the last 5 years (2021-2026) on neurodegenerative diseases associated with miRNA dysregulation, including Alzheimer's Disease (AD), Parkinson's Disease (PD), Amyotrophic Lateral Sclerosis (ALS), and Huntington's Disease (HD).",

Bioinformatics-based network pharmacology study. Publicly available gut microbial metabolite, metabolite-target, and disease-associated gene data sets related to AMD, DR, and RVO were analyzed. Gut microbial metabolites were retrieved from gutMGene, and potential human targets were predicted using the Similarity Ensemble Approach and SwissTargetPrediction. Disease-associated genes were collected from GeneCards, Online Mendelian Inheritance in Man, and the Comparative Toxicogenomics Database. Intersection genes were analyzed using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses. Protein-protein interaction networks were constructed using the Search Tool for the Retrieval of Interacting Genes/Proteins database, and candidate hub targets were prioritized in Cytoscape. Drug-likeness and toxicity profiles of key metabolites were evaluated using SwissADME and ADMETlab 3.0. An integrated microbiota-substrate-metabolite-target (M-S-M-T) network was constructed to characterize gut-eye axis regulation. Intersection genes, enriched biological functions and pathways, high-centrality candidate hub targets, predicted drug-likeness and toxicity profiles of metabolites, and M-S-M-T regulatory relationships. A total of 226 gut microbial metabolites and 1518 predicted host targets were identified. Intersection analysis revealed 47, 44, and 40 metabolite-related genes associated with AMD, DR, and RVO, respectively, including 38 genes shared across all 3 diseases. Enrichment analyses showed convergent involvement of microbial signal sensing, inflammatory regulation, oxidative stress, apoptosis, and vascular homeostasis. Nuclear factor kappa B, mitogen-activated protein kinase, phosphatidylinositol 3-kinase-protein kinase B, tumor necrosis factor, VEGF, Toll-like receptor, and nucleotide-binding oligomerization domain-like receptor pathways formed a shared inflammatory-oxidative-vascular signaling module. Protein-protein interaction analysis identified interleukin 6, tumor necrosis factor, protein kinase B alpha, and tumor protein p53 as recurrent high-centrality candidate hub targets. Key metabolites, including indole-3-propionic acid, tryptamine, phenylalanine, and indole-3-lactic acid, showed favorable predicted drug-likeness and safety profiles. Gut microbial metabolites may contribute to AMD, DR, and RVO through shared inflammatory, oxidative stress, and vascular signaling networks. These findings provide a systems-level framework for gut-eye axis regulation and support further experimental validation of microbiota-based systemic intervention strategies.

Around one-third of patients have metastatic disease at diagnosis, while involvement of the foot is rare, accounting for only 5% of cases. For patients without metastases, treatment typically includes neoadjuvant chemotherapy, limb salvage surgery when possible, and adjuvant chemotherapy. Recent advances in 3D printing enable customized, patient-specific reconstruction in complex anatomical sites, such as the calcaneus. A 19-year-old female, previously healthy, presented with progressive left heel pain for 1 year without constitutional symptoms or trauma. Clinical observation revealed a swollen heel with intact overlying skin, no deformity, and no limitation of range of motion or neurovascular deficits. Radiologic local and systemic staging showed a nonmetastatic, aggressive, lytic, ill-defined lesion in the left calcaneus on x-ray, with MRI demonstrating a heterogeneously enhancing calcaneal tumor with soft-tissue extension into the heel fat pad and sinus tarsi. Histopathology of the image-guided true-cut biopsy specimen confirmed the diagnosis of Ewing sarcoma and primitive neuroectodermal tumor with EWSR1-FLI1 translocation. After multidisciplinary tumor board discussion, the patient received neoadjuvant chemotherapy with alternating vincristine, doxorubicin, cyclophosphamide, ifosfamide, and etoposide, resulting in tumor regression and good response on restaging. She then underwent limb salvage total calcanectomy. Reconstruction involved a custom-made, 3D-printed mold to fabricate an antibiotic-impregnated polymethylmethacrylate (PMMA) cement spacer, secured with two cannulated screws to the talus and Achilles tendon reattachment. After initial closure, the patient developed wound dehiscence, requiring a free radial forearm flap. She resumed adjuvant chemotherapy. At 1-year follow-up, the patient ambulated with a cane and a Toronto Extremity Salvage Score of 62.5%. By 2.5 years, she developed a deep surgical site infection (Enterococcus faecalis), managed by multiple irrigations, debridement, and implant removal. The infection resolved, the wound healed, and there were no signs of recurrence or metastasis. This case underscores the feasibility of limb salvage surgery in calcaneal primary malignant neoplasm, using versatile reconstructive options including custom 3D-printed prosthetic implants, cement spacers, and total calcanectomy without reconstruction.",

Yet, due to light scattering, two-photon (2P) functional calcium imaging has been largely confined to superficial cortical layers in rodent models. Three-photon (3P) excitation offers deeper penetration due to reduced scattering of longer excitation wavelengths, but lower repetition rates of 3P laser systems impose a significant limitation on temporal resolution. Therefore, 3P calcium imaging of cortical microcircuits is still in its infancy. In this study we performed a back-to-back comparison of 2P and 3P functional calcium imaging in the visual cortex of awake, head-fixed mice. We assessed the efficacy of 3P imaging to capture the local functional microcircuit dynamics in the visual cortex. 3P imaging not only revealed neuronal somata and neuropil in layers V/VI with robust morphological SNR but also generated label-free contrast of the blood vessels via 3rd harmonic generation. Functionally, in superficial layers, a comparable functional architecture was assessed with both methods; while 3P detected lower firing frequencies, the underlying circuit dynamics, such as functional connectivity, remained consistent with 2P recordings. Notably in layers V/VI, while 2P failed to resolve the functional circuit state, with 3P a functional readout of neuronal circuits became achievable. These results demonstrate that, despite its current temporal limitations, 3P calcium imaging can reliably capture the functional architecture across all cortical layers, providing unmatched depth penetration and vascular contrast.",

In response, microneedle (MN) technology has emerged as a minimally invasive, highly versatile platform for wound healing by enabling direct delivery of therapeutics into viable tissue while also supporting wound monitoring and microenvironment modulation. Moreover, advances in MN fabrication techniques, such as micromolding, 3D printing, and centrifugal drawing, enable precise control over needle geometry, mechanical strength, and drug-loading strategies. Diverse MN designs, including dissolvable, swellable, porous, hollow, separable, and multifunctional types, have consequently expanded therapeutic functionality beyond passive drug delivery to encompass immunomodulation, antimicrobial action, angiogenesis, neurovascular regeneration, antioxidative protection, and scar remodeling. Further, intelligent MN systems combine biosensing with stimuli-responsive drug release, enabling real-time monitoring and on-demand therapy tailored to the changing wound environment. This review summarizes recent advances in MN fabrication methods, structural designs, and integration with other scaffolds.

This study investigated L-DOPA's post-treatment functional protection with transcriptional changes in the diabetic murine retina. Assessing retinal and visual function with electroretinography (ERG) and optomotor response (OMR), functional deficits were confirmed in streptozotocin (STZ)-induced diabetic mice. Control and diabetic mice were then treated with continuous L-DOPA/carbidopa (four weeks), L-DOPA/carbidopa (two weeks) followed by washout (two weeks), or vehicle (four weeks). Functional assessments were repeated during the final two weeks, alongside assessment of flicker-evoked retinal vasodilation. After bulk RNA sequencing of retinal tissue, differential gene expression analysis alongside weighted gene co-expression network analysis were performed to determine disease- and treatment-sensitive changes in retinal gene co-expression that correlated with functional protection. After L-DOPA treatment in diabetic mice, ERG oscillatory potential timing and OMR performance were protected for at least two weeks past treatment end. Flicker-induced venule vasodilation also maintained post-treatment improvement, with protective trends in arteriole vasodilation. Differentially expressed genes were comparable between diabetic mice experiencing L-DOPA washout versus continued L-DOPA treatment. Gene co-expression network analysis identified distinct modules across L-DOPA-treated diabetic mice associated with synaptic function and cytoskeletal organization that correlated with functional protection. These findings demonstrate that L-DOPA restores retinal neurovascular function with post-treatment effects in early DR and links this protection to transcriptional programs supporting synapse activity and structural integrity.",

This study evaluates the safety and accuracy of the fully active robotic system. A retrospective observational study of 315 consecutive RA-TKAs was conducted over a period of 15 months. Primary outcomes included safety (neurovascular injury, ligamentous injury, pin-site complications) and accuracy (concordance between preoperative 3D CT planning and fi nal implant size & targeted polyethylene size). The robotic procedure was successfully completed in 315cases, and 3 cases were abandoned (n=318). Tibial component size concordance was 100%, while femoral concordance was 98.7%. Target polyethylene thickness (9-11mm) was achieved in 97.8% of cases. Safety outcomes showed zero neurovascular or MCL injuries. Iatrogenic PCL injury occurred in one case (0.32%) following a system interruption. Pin-site discharge(1.6%) was observed exclusively in the fi rst 104 cases, and no cases were reported after transitioning to intra-incisional pin placement.

However, current evidence consists predominantly of small-sample, single-arm studies, and quantitative synthesis of key outcomes-technical success, operative times, and radiation dose-with refinement by procedure type remains lacking. This study was guided by three prespecified research questions: (1) What is the pooled technical success rate of CorPath GRX-assisted cerebral aneurysm embolization and diagnostic angiography? (2) What are the pooled operative times and radiation doses associated with these procedures? (3) Do these outcomes differ significantly between embolization and angiography subgroups? We therefore conducted a systematic review and single-arm meta-analysis to evaluate the performance of the CorPath GRX system in these two core neurovascular applications. We systematically searched PubMed, Embase, Cochrane Library, and Web of Science up to May 1, 2026, for single-arm studies evaluating CorPath GRX-assisted neurovascular interventions. The primary outcomes were technical success rate, total procedural time, robotic operation time, fluoroscopy time, and radiation dose. A random-effects model was applied when substantial heterogeneity was present (I\u00b2 \u2265 50%). Subgroup analyses were performed by procedure type (embolization vs. angiography), country/region, sample size, and study design. In the present evaluation, methodological rigor was assessed against the standards set forth in the JBI checklist for case series. Seven studies comprising 265 patients were included. The pooled technical success rate was 87% (95% CI: 75%-96%), with 94% (95% CI: 90%-96%, I\u00b2 = 0.0%) in the embolization subgroup and 76% (95% CI: 63%-87%, I\u00b2 = 69.4%) in the angiography subgroup. The pooled total procedural time, robotic operation time, and fluoroscopy time were 122.58\u00a0min (95% CI: 112.81-132.36), 60.68\u00a0min (95% CI: 44.40-76.97), and 30.70\u00a0min (95% CI: 18.99-42.41), respectively. The pooled radiation dose (three studies, air kerma) was 1,340.84 mGy (95% CI: 485.65-2,196.03), with high heterogeneity (I\u00b2 = 97.0%). Subgroup analyses revealed that procedure type and study design significantly influenced operative times and technical success rate. JBI assessment identified six studies as high quality and one study as low quality This systematic review and single-arm meta-analysis provides preliminary, hypothesis-generating evidence that the CorPath GRX system is technically capable of performing both cerebral aneurysm embolization and diagnostic cerebral angiography in carefully selected patients, with encouraging performance observed in the embolization subgroup in early-stage experiences. However, all available evidence derives from small-sample, non-comparative, single-arm studies. The substantial heterogeneity across outcomes (I\u00b2 > 60% for most endpoints) further underscores that these pooled estimates are exploratory and not definitive. The pooled radiation dose (based on only three studies with high heterogeneity) remains inconclusive. Robotic-assisted neurovascular procedures should therefore be regarded as a novel, technology-driven approach with demonstrated procedural feasibility in highly selected, early-stage clinical contexts, rather than an evidence-based standard of care. Future prospective, multicenter, comparative studies with standardized definitions and systematic reporting of learning curves and conversion rates are urgently needed to define its incremental clinical value.",

This review aims to explore the use of blood-based NfL as an endpoint in clinical trials of neurodegenerative conditions. A database search of MEDLINE and EMBASE was conducted to identify interventional clinical trials and/or related post hoc analyses for neurodegenerative diseases, published between 2013 and 2024 that reported the use of serum or plasma NfL as an endpoint. Additional studies from reference lists of included trials were manually considered for inclusion where relevant. Data were charted descriptively by disease type and summarised. 49 studies were included, 29 in multiple sclerosis (MS), eight in amyotrophic lateral sclerosis (ALS), six in Alzheimer's disease (AD), and six in other diseases. Across studies, reductions in NfL often paralleled improvements in primary efficacy outcomes, supporting its use as a biomarker of disease activity and treatment response. However, several studies demonstrated a lack of concordance between change in NfL and in clinical outcomes, some of which may be related to the non-disease-modifying mechanisms of the interventions studied. This necessitates careful consideration when applying blood-based NfL as a biomarker endpoint for studies involving such interventions. Blood NfL is a promising biomarker with potential utility as a surrogate endpoint in neurological clinical trials, particularly for diseases with active axonal injury. Further validation, particularly around disease- and intervention-specific interpretation, is needed before blood NfL can be incorporated more routinely as a clinical endpoint.",

These roles are often considered independently, obscuring why lactate supports neuronal function in some settings yet accompanies persistent inflammation and neurodegeneration in others. This review introduces a lactate signal-decoding framework that emphasizes cellular interpretation rather than concentration alone. The framework integrates the lactate/pyruvate ratio, the cytosolic reduced-to-oxidized nicotinamide adenine dinucleotide (NADH/NAD\u202f+\u202f) state, lactate dehydrogenase (LDH) isoenzyme context, proton-coupled monocarboxylate transport, extracellular pH, hydroxycarboxylic acid receptor 1 (HCAR1) signaling, and enzymatic or non-enzymatic lactylation. We compare neuronal, astrocytic, microglial, and neurovascular responses and examine how aging, apolipoprotein E \u03b54 (APOE4), amyloid pathology, hypoperfusion, sleep disruption, and systemic metabolic disease reshape them. Particular attention is given to the chemistry and analytical validation of histone and non-histone lactylation; the proposed interaction of tau lactylation with other post-translational modifications; and links to proteostasis, iron homeostasis, and mitochondrial quality control. As a hypothesis-generating model, AD progression may involve loss of coordination among lactate transport, oxidation, receptor signaling, pH control, and covalent modification. This framework prioritizes restoration of metabolic coordination over indiscriminate lactate suppression and identifies biomarker and experimental requirements for clinical translation.",

It is important to detect the retinal abnormalities early to avoid the progression of the disease and permanent loss of vision. In this regard, the framework proposed provides an effective and automated method of DR screening with retinal fundus images. The model combines the merits of attention-based and transformer-based models and the You Only Look Once (YOLO) detection model to improve the level of feature representation and detection quality. It is intended to do multi-task learning such as lesion detection, accurate segmentation, and severity of DR stages. The framework is tested using well known publicly available databases like APTOS, EyePACS, and Messidor which are robust and reliable. The experimental findings suggest that Attention Transformer-YOLO for Diabetic Retinopathy Detection (AT-YOLO-DR) is more accurate especially with respect to the detection of small and subtle lesions, and it is also characterized by better generalization than the current deep learning models. The system offers a scalable, reliable and practical solution to real life clinical screening applications.",

Alzheimer's disease, Parkinson's disease, Amyotrophic lateral sclerosis, Huntington's disease, Frontotemporal dementia are examples of diseases. While different clinically, these disorders have a common genetic, molecular and cellular basis. This review examines the common genetic pathways, along with the interactions between genes of major neurodegenerative diseases, with a focus on the key genes, such as APOE, SNCA, MAPT, TARDBP, LRRK2 and HTT. The common pathogenic mechanisms considered to play a major role in disease progression include protein misfolding and aggregation, mitochondrial dysfunction, oxidative stress, neuroinflammation, diminished autophagy, and impaired lysosomal function, as well as synaptic degeneration. The review also emphasizes the role of systems biology strategies, such as genome-wide association studies, transcriptomics, proteomics, metabolomics, interactome analysis, and multi-omics integration, to unveiling complex molecular networks in neurodegeneration. Furthermore, the emerging biomarker strategies and therapeutic strategies targeting convergence signaling pathways including NF-\u03baB, PI3K-Akt-mTOR, MAPK and Wnt/\u03b2-catenin are summarized. The common genetic basis and the cross-connecting molecular mechanisms of the various neurodegenerative diseases could help in the discovery of new biomarkers and pan-therapeutic targets. Further advances in molecular genetics, computational biology and precision medicine are needed to enhance early detection and the creation of effective disease-modifying treatments.",

Venous sinus stenting (VSS) directly addresses venous outflow obstruction and has emerged as a therapeutic option; however, outcome data remain heterogeneous. We performed an updated systematic review and meta-analysis to evaluate the efficacy and durability of VSS for PT and to compare outcomes between IIH-associated and isolated PT. MEDLINE, Scopus, and Web of Science were searched from inception through December 2025 following PRISMA guidelines. Clinical studies reporting PT outcomes after VSS were included. Random-effects meta-analyses of proportions were conducted to estimate pooled rates of overall improvement, complete resolution, and recurrence. Prespecified subgroup analyses compared IIH versus isolated PT. Thirty-two studies comprising 850 patients were included (641 with IIH; 209 with isolated PT). Venous sinus stenosis accounted for 90.3% of treated etiologies. The pooled rate of overall PT improvement was 89.8% (95% CI, 85.5-92.9). Complete resolution occurred in 87.1% (95% CI, 82.5-90.6). Recurrence at last follow-up was 10.9% (95% CI, 8.3-14.2). Improvement and complete resolution rates did not differ significantly between IIH and isolated PT. Recurrence was higher in IIH (12.0%) than in isolated PT (5.7%), without reaching statistical significance. VSS is associated with high rates of PT improvement and complete resolution with low recurrence. Recurrence trends appear higher in IIH, suggesting underlying pathophysiology may influence durability.",

To investigate altered neurofluid dynamics in women with insomnia using indirect neuroimaging markers. Prospective. 46 healthy controls (HC; 56.3\u2009\u00b1\u20095.5\u2009years) and 28 females with insomnia disorder (ID; 58.2\u2009\u00b1\u20094.9\u2009years). 3.0\u2009T, 3D T1-weighted magnetization-prepared rapid acquisition gradient echo, resting-state fMRI using gradient-echo echo-planar imaging, and multi-shell diffusion MRI using spin-echo-planar sequence. (1) Blood oxygen level dependent cerebral spinal fluid (BOLD-CSF) coupling measuring temporal coordination between neurovascular and CSF oscillations, (2) diffusion tensor image analysis along the perivascular space (DTI-ALPS) quantifying directional diffusivity in periventricular white matter, (3) choroid plexus (ChP) volume reflecting morphology of primary CSF-producing structures, and (4) nucleus basalis of Meynert (NBM) volume evaluating cholinergic system integrity potentially relevant to vascular regulation; (5) all participants completed self-reported sleep measures, including the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), and Fatigue Severity Scale (FSS), and also underwent cognitive function testing. Analysis of covariance evaluated between-group differences controlling for demographic and clinical covariates. Relationships with cognitive and sleep scores were assessed using partial correlations, stratified by group only when significant interaction effects were detected. Multiple comparisons were false discovery rate corrected (p\u2009<\u20090.05). Classification model performance was evaluated using the area under the receiver operating characteristic curve (AUC). Model comparisons were performed using DeLong's tests (\u0394AUC) and stepwise likelihood ratio tests (LRT) to assess classification gain and the independent incremental contribution of each biomarker; all tests were two-sided with \u03b1\u2009=\u20090.05. Compared to controls, insomnia patients showed significantly reduced BOLD-CSF coupling (-0.18\u2009\u00b1\u20090.20 vs. -0.32\u2009\u00b1\u20090.17), indicating altered temporal coordination between neurovascular and CSF dynamics. ChP volume was significantly enlarged in the insomnia group (1.72%\u2009\u00b1\u20090.42% vs. 1.55%\u2009\u00b1\u20090.39% of total intracranial volume), potentially reflecting compensatory CSF production upregulation, inflammatory changes, or vascular remodeling. NBM volume was significantly reduced in insomnia patients (201.75\u2009\u00b1\u200917.66 vs. 217.47\u2009\u00b1\u200921.04\u2009mm3), suggesting cholinergic system alterations. In contrast, the DTI-ALPS index did not differ between groups (p\u2009=\u20090.85). BOLD-CSF coupling positively correlated with PSQI (r\u2009=\u20090.34), ISI (r\u2009=\u20090.41), and FSS (r\u2009=\u20090.40); ChP volume positively correlated with ISI (r\u2009=\u20090.32) and FSS (r\u2009=\u20090.35) (all FDR-corrected). A dataset consists of 74 participants (46 HC and 28 ID) were included, the four-marker classification model achieved moderate performance (AUC\u2009=\u20090.785, accuracy\u2009=\u200971.9%). Multiple indirect neuroimaging markers potentially related to neurofluid dynamics were altered in middle-aged and older women with chronic insomnia, except for DTI-ALPS. These findings include altered neurovascular-CSF coordination, ChP enlargement, and cholinergic system volume reduction. 2. Stage 2. Insomnia is common in middle\u2010aged and older women, but its effect on the brain's waste\u2010clearance system, known as glymphatic system, remains unclear. Using several magnetic resonance imaging (MRI) to compare 28 women with insomnia and 46 women who slept well. Three measures differed between the groups. Insomnia group showed weaker coordination between brain activity and cerebrospinal fluid flow, a larger choroid plexus (the tissue that makes this fluid), and a smaller nucleus basalis of Meynert (a region that helps control brain blood flow). A fourth, diffusion\u2010based measure did not differ. These results link insomnia to measurable changes in how the brain manages its fluids.",

A secondary analysis of data from the Global Burden of Disease (GBD) 2021 study was conducted by using estimates of blindness and vision loss due to DR across different socio-demographic index (SDI) categories. Age-standardised prevalence rates, relative percentage changes, net drift and local drift were analysed. Globally, age-standardised prevalence (ASPR) of diabetes-related blindness and vision loss rose from 48.8 per 100\u2009000 in 1990 to 67.3 per 100\u2009000 in 2021, with type 1 diabetes-related blindness and vision loss ASPR showing a modest decrease (from 1.8 to 1.7 per 100 000). The highest relative increase was recorded in the high SDI group (45.8%). For Type 1 diabetes, low-middle and low SDI groups exhibited more pronounced declines in associated ASPR. Increasing ASPR with advancing age was consistent across SDI groups though less pronounced for type 1 than type 2 diabetes. Unfavourable period and cohort effects were observed for type 2 but not type 1-related blindness and vision loss risk. High-middle SDI and middle SDI groups showed the most notable increase in period and cohort effect, whereas low-middle and low SDI groups experienced favourable period and cohort risks during the study duration. Substantially different trends were observed for ASPR, period and cohort effects in recent decades for type 1 versus type 2 diabetes across different SDI.",

While AI shows promise in controlled clinical settings (e.g., stroke imaging, melanoma detection), consumer-facing tools often provide overconfident, context-free diagnostic assertions (e.g., 'definitive evidence of ALS'), leading to premature and potentially harmful life-altering decisions. To highlight the clinical, ethical, and regulatory risks of unregulated AI in ALS diagnosis and propose actionable solutions. We present a case of AI-mediated misdiagnosis, analyze the limitations of consumer-facing AI (lack of clinical context, longitudinal data, and specialist oversight), and discuss the \"authority paradox\" (patients trusting AI outputs over clinicians' nuanced assessments). We propose a structured 4-step clinical approach for managing AI-mediated self-diagnoses and urge regulators to classify such tools as high-risk under the EU AI Act. The uncritical adoption of consumer AI in ALS diagnosis represents a public health risk. Clinicians, regulators, and developers must collaborate to ensure AI serves patients safely and ethically.",

A single-centre, retrospective analysis of adults with T1D using Omnipod 5 was conducted. Case notes were reviewed for routinely collected clinical data. Continuous glucose monitoring (CGM) metrics were obtained from cloud-based platforms at 3, 6 and 12\u2009months. Paired data were analysed with two-tailed t-tests or Wilcoxon signed-rank, with results presented as mean (SD) or median (IQR). One hundred individuals were included (63% female). At baseline, median age was 28 (23.0-37.8) years, BMI 27.0 (22.3-30.0) kg/m2, diabetes duration 16.0 (9.0-24.8) years and mean HbA1c 68 (\u00b118.0) mmol/mol. Over half (52%) transitioned from multiple daily injections. Significant glycaemic improvements were observed by 3\u2009months. Improvements were durable to 12\u2009months, with mean HbA1c falling from 68.5 to 58.8\u2009mmol/mol (p\u2009<\u20090.001, n\u2009=\u200975) and time in range (TIR) increasing from 43.4% to 58.3% (p\u2009<\u20090.001, n\u2009=\u200986). The greatest glycaemic improvements were observed in those with lower TIR at baseline. Retinopathy progression occurred in a minority of 10 individuals, all of whom had a baseline HbA1c >\u200953\u2009mmol/mol. Initiation of Omnipod 5 was associated with durable glycaemic improvements. Preliminary data generate the hypothesis that retinopathy progression may be concentrated among individuals with baseline HbA1c above target range.

Targeted neonatal echocardiography (TNE) enables detailed hemodynamic assessment to guide stabilization and embolization timing. We evaluated a multidisciplinary, TNE-guided protocol to optimize individualized care and shorten shunting duration. Single-center case series of five neonates with HFCVM admitted to a Level IV NICU (June 2022-June 2025). The protocol incorporated serial TNE for prenatal diagnosis, pre-/post-embolization care, and intra-procedural monitoring. TNE categorized cardiovascular phenotypes, guided embolization timing, and monitored cardiac function. Five neonates with HFCVM were managed using this protocol. Median number of embolizations per neonate were 2 (2.0-2.5). Four patients exhibited flow-mediated physiology with high cardiac output and ductal-dependent systemic perfusion. Four patients survived to discharge. One patient experienced a fatal intracranial hemorrhage. A physiology-driven, TNE-guided approach for neonatal HFCVM is feasible and supports tailored hemodynamic management and staged embolization. Prospective multicenter validation is warranted.",
        "42477295": "ID: 42477295\nTitle: Ocular Manifestations of Metabolic Syndrome: A Systemic Vascular Phenotype.\nAbstract: Metabolic syndrome (MetS) is defined by central obesity, insulin resistance, hypertension and dyslipidemia. MetS affects over one-third of US adults. Beyond its cardiovascular burden, MetS has clinically relevant associations with ocular health and may contribute to a systemic vascular and neuro-metabolic phenotype involving the retina, optic nerve, lens, ocular surface and choroid. This narrative review searched PubMed through May 2026 using combinations of free-text and MeSH-based terms related to 'metabolic syndrome', 'insulin resistance', 'obesity', 'hypertension', 'dyslipidemia', 'diabetes', 'diabetic retinopathy', 'diabetic macular edema', 'glaucoma', 'cataract', 'dry eye', 'macular degeneration', 'retinal vascular occlusion' and 'optic neuropathy'. Reference lists of relevant reviews and primary studies were also screened. English-language human, translational, epidemiologic, clinical-trial, systematic-review and meta-analysis articles were prioritized. This was not designed as a systematic review, and formal PRISMA screening, risk-of-bias grading and meta-analysis were not performed. MetS and its components are associated with diabetic retinopathy, diabetic macular edema (DME), non-diabetic retinopathy, primary open-angle glaucoma, cataract, dry eye disease, age-related macular degeneration (AMD), retinal vascular occlusions and non-arteritic anterior ischemic optic neuropathy (NAION). Shared mechanisms include chronic inflammation, oxidative stress, endothelial dysfunction, insulin resistance-driven retinal neurodegeneration, dyslipidemia-related lipotoxicity, hypertension-related microvascular injury and microvascular rarefaction. Management requires both systemic risk-factor optimization and disease-specific ophthalmic therapy, including anti-VEGF therapy, intraocular pressure reduction, laser or surgical procedures when indicated, ocular surface-directed therapy and cataract surgery when visually significant. Ocular complications associated with MetS are common and may be vision-threatening. Risk-based ocular surveillance and metabolic optimization are justified, particularly in patients with diabetes, hypertension, dyslipidemia, visual symptoms or established vascular disease. However, the strength of disease-specific evidence varies: interventional evidence is strongest for diabetic retinopathy risk reduction and glaucoma treatment through intraocular pressure lowering, whereas evidence for AMD, NAION, RVO, cataract and dry eye disease is more frequently observational or indirect.",
        "42477610": "ID: 42477610\nTitle: Tyrosine kinase inhibitor-associated cerebral vasculopathy with a distinct non-enhancing vessel wall phenotype: a case report.\nAbstract: Tyrosine kinase inhibitors (TKIs) are associated with adverse vascular events, including cerebrovascular stenosis. However, most reported cases rely on luminal imaging, and the arterial wall characteristics of TKI-associated vasculopathy remain insufficiently characterized. A 47-year-old man with chronic myeloid leukemia developed recurrent transient ischemic attacks during long-term exposure to multiple tyrosine kinase inhibitors, including sequential treatment with nilotinib and ponatinib. Neurovascular imaging revealed extensive multifocal steno-occlusive lesions involving both intracranial and extracranial arteries, accompanied by severe hemodynamic compromise. High-resolution vessel wall MRI demonstrated diffuse circumferential wall thickening with negative remodeling in both distal internal carotid arteries and eccentric thickening along the anterior walls of the bilateral M1 segments of the middle cerebral artery. Notably, no definite mural enhancement was observed. Following discontinuation of ponatinib and transition to alternative therapy, cerebral perfusion improved at two months, and the patient remained clinically stable without recurrent ischemic events. This case illustrates a potentially distinct vessel wall thickening pattern in TKI-associated vasculopathy, providing information beyond luminal stenosis. The absence of definite mural enhancement and clinical and hemodynamic improvement after treatment modification suggest a drug-related vascular component. Vessel wall imaging may aid in the evaluation of this condition and inform management strategies.",

While anti-vascular endothelial growth factor (VEGF) therapy is effective, its utility is limited by variable patient response and the need for frequent injections. Therefore, identifying new therapeutic targets for DR is imperative. Emerging evidence indicates that astrocytes contribute to endothelial dysfunction in DR, suggesting that targeting astrocyte-endothelial cell crosstalk represents a promising therapeutic strategy. To evaluate the therapeutic potential of Salvianolic acid A (Sal A) for DR, elucidate the molecular mechanisms by which it modulates astrocyte-endothelial cell interactions, and develop a liposome-based nanodelivery system to enhance its efficacy. The protective effects and mechanisms of Sal A were systematically investigated using a streptozotocin (STZ)-induced diabetic mouse model, complemented by a suite of in vitro and molecular approaches including co-culture models, transcriptomic analysis, and target validation assays. Retinal vascular structure and barrier function were assessed in vivo via immunofluorescence staining and Evans Blue leakage assays. Endothelial cell behaviors were examined in vitro using wound healing, Transwell migration, tube formation, and spheroid sprouting assays. Transcriptomic profiling was performed by RNA sequencing (RNA-seq). The direct target of Sal A was identified and validated using MS-based drug-affinity responsive target stability (DARTS) screening, cellular thermal shift assay (CETSA), and microscale thermophoresis (MST). Expression of key signaling molecules was measured by western blotting, enzyme-linked immunosorbent assay (ELISA), and quantitative real-time PCR (qRT-PCR). Liposome@Sal A was prepared and characterized for its physicochemical properties (dynamic light scattering, transmission electron microscopy), stability, and therapeutic efficacy in vitro and in vivo. Sal A treatment ameliorated retinal vascular abnormalities in diabetic mice, evidenced by increased VE-cadherin and NG2 expression, decreased \u03b1-smooth muscle actin (\u03b1-SMA) expression, and reduced acellular capillary formation, collectively restoring vascular integrity. Mechanistically, astrocyte-derived soluble Semaphorin 4D (sSema4D) promoted endothelial hyperactivation via the PlexinB1/RhoA/ROCK/pMLC2 signaling cascade. Sal A directly bound to the Arg92 residue of membrane-bound Sema4D on astrocytes, significantly inhibiting sSema4D shedding and its subsequent deleterious effects on endothelial cells. Furthermore, Liposome@Sal A enhanced retinal drug delivery and demonstrated superior therapeutic efficacy compared to free Sal A in diabetic mice. Sal A preserves retinal vascular structure and function in DR by binding to astrocytic Sema4D at Arg92, thereby inhibiting sSema4D shedding and downstream PlexinB1/RhoA/ROCK/pMLC2 signaling, which modulates astrocyte-endothelial cell crosstalk. Liposomal encapsulation significantly potentiates the therapeutic efficacy of Sal A, positioning it as a promising drug candidate for DR treatment.",
        "42477693": "ID: 42477693\nTitle: Subcutaneous transplantation of lung organoids ameliorates vascular dementia via the IGFBP7-Ago2 mediated lung-brain axis.\nAbstract: Vascular dementia (VaD), whose leading cause is chronic cerebral hypoperfusion (CCH), currently has no approved effective disease-modifying therapies. The lung-brain axis mediates crosstalk between the lung and the nervous system, yet the specific mediators underlying its role in VaD remain unclear. This study demonstrated that subcutaneous transplantation of lung organoids (LO) ameliorated cognitive dysfunction in a mouse model of bilateral common carotid artery stenosis (BCAS). We showed that BCAS-induced CCH downregulated pulmonary expression of insulin-like growth factor-binding protein 7 (IGFBP7), a key mediator of the lung-brain axis. LO transplantation restored\u200bcirculating IGFBP7, which translocated to the brain and acted directly on microglia by binding to Argonaute2 (Ago2), thereby inhibiting pro-inflammatory signaling pathways, reducing neurovascular damage and neuroinflammation, and alleviating\u200bperipheral lung injury caused by CCH. Notably, LO transplantation concurrently restores cerebral function and pulmonary homeostasis, with concurrent recovery of endogenous pulmonary IGFBP7 expression in BCAS mice, indicating concurrent improvement of both brain and lung pathology through lung-brain axis crosstalk. This study confirmed that LO transplantation represented an effective biotherapy for VaD and identified the IGFBP7-Ago2 axis as a core regulatory pathway of the lung-brain axis. These findings provide mechanistic insights into the pathogenesis of VaD and highlight that IGFBP7 is a potential therapeutic target for restoring inter-organ crosstalk in dementia."
