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.

This narrative review examines four mechanistically distinct compounds, namely spermidine, fisetin, berberine, and urolithin A, as emerging functional food ingredients with scientifically supported effects on key hallmarks of human aging. Spermidine, a dietary polyamine from wheat germ and fermented foods, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Fisetin, a flavonoid from strawberries and apples, exerts senolytic activity by selectively eliminating senescent cells via PI3K/AKT and Bcl-2/Bcl-xL inhibition, with emerging clinical evidence. Berberine, an isoquinoline alkaloid from Berberis species, modulates metabolic dysfunction via AMP-activated protein kinase (AMPK) activation and reshapes gut microbiota composition through direct high intraluminal exposure, with the most extensive clinical dataset of the four compounds. Urolithin A, a gut microbiome-derived postbiotic from ellagitannins in pomegranates and nuts, induces mitophagy via PINK1/Parkin and has been evaluated in a growing number of registered human clinical trials. Together, the four compounds primarily target distinct but complementary aging-associated pathways (autophagy, senolysis, metabolic regulation, mitophagy), suggesting rational potential for combined functional food formulations. Limited direct evidence for their combined use and the need for dedicated co-administration studies are discussed, alongside bioavailability, safety, and regulatory considerations."

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.

We reanalysed the Genetic and Epigenetic Signatures of Translational Ageing Laboratory Testing(GESTALT) paired RNA sequencing (RNA-seq) and tandem mass tag (TMT) proteome from 82 donors (aged 22-89) using Data Integration Analysis for Biomarker discovery using Latent cOmponents (DIABLO) for supervised multi-omics integration, weighted gene co-expression network analysis (WGCNA), external Genotype-Tissue Expression(GTEx) transcriptomic comparison, network medicine proximity mapping and CDOCKER molecular docking. Three analyses converged on the autophagy-lysosome axis: Kyoto Encyclopaedia of Genes and Genomes (KEGG) Lysosome ranked first in discordant-quadrant analysis; gene set enrichment analysis (GSEA) identified vacuole organisation and macroautophagy as the top age-upregulated Gene Ontology (GO) terms; and WGCNA recovered KEGG Lysosome in the brown module. Module regression localised most proteomic age signals to the lysosomal degradative-capacity module, whereas the proteasome was unaffected. McNemar testing and GTEx comparison supported a protein-side, post-transcriptional origin. TCIRG1, CTSA and ATP6V0D1 were recurrent hubs. Network proximity computationally prioritised hydroxytyrosol as a lysosomal-degradative-capacity-preferential candidate, and CDOCKER on cathepsin A linked its advantage over tyrosol to an ortho-hydroxyl group forming additional hydrogen bonds. These results support protein-layer-dominant autophagy-lysosome remodelling as a feature of dermal fibroblast ageing and suggest a cell-type-resolved computational route from ageing proteomics to testable dietary candidates."

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application."

While fetal lung signals are known to help initiate labor, the role of the placenta has remained unclear. Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice. Our findings reveal that placental AOC1-spermidine-EIF5A-autophagy axis is essential for parturition timing and offer a potential therapeutic strategy for preterm birth."

Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration. Beyond its canonical role in macroautophagy, membrane atg8ylation also occurs on preexisting, non-autophagosomal single membranes through Conjugation of ATG8s to Single Membranes (CASM), positioning this pathway as a rapid response to membrane stress. Two E3-like ligase complexes, ATG16L1-ATG5-ATG12 and TECPR1-ATG5-ATG12, act as complementary sensors of lysosomal injury by detecting distinct physicochemical cues, including proton gradient collapse and lipid scrambling. These ligases convert damage signals into spatially restricted membrane atg8ylation, generating a membrane-associated platform that coordinates multiple downstream pathways. These include ESCRT-dependent membrane repair, ER-lysosome lipid transfer, membrane tubulation, and stress granule formation. When repair fails, membrane atg8ylation regulates lysophagy and activates lysosomal biogenesis and regeneration to restore lysosomal homeostasis. These emerging findings define membrane atg8ylation as a central organizer of membrane quality control rather than a pathway merely confined to macroautophagy. In this review, we summarize the current understanding of how membrane atg8ylation detects lysosomal damage and how this pathway coordinates other lysosomal quality control mechanisms to maintain lysosomal integrity."

This review summarizes recent advances in understanding how HDL function is affected by its associated proteins, demonstrating that this is a more appropriate lens through which to assess HDL's protective capacity. Recent publications have demonstrated an inverse relationship between ApoM and clinical outcomes in chronic kidney disease and its concomitant cardiovascular indications. Mechanistic studies show that ApoM's regulation of mitochondrial function and autophagy are likely contributors to this effect. Additionally, ApoA-I, serum amyloid albumin (SAA), and SR-B1 have recently been highlighted as key regulators of atherogenesis through their ability to prevent LDL transcytosis and arterial entrapment by proteoglycans. Lastly, a novel mechanism is described wherein HDL-bound endotoxin is degraded through the endosome-lysosome pathway in an SR-B1-dependent manner, attenuating IL-1\u03b2 activation. In the same study, inhibition of CETP (cholesterol ester transfer protein) increased HDL and improved mortality in a mouse model of sepsis, highlighting this pathway's importance and therapeutic potential of CETP inhibition, which is currently in key clinical trials. HDL regulates inflammation and CVD through a variety of mechanisms independent of reverse cholesterol transport, including autophagy, LDL deposition, endotoxin clearance."

Although these disorders have different clinical features which affect cognition, movement and other vital body functions, they share key underlying molecular and cellular processes. This starts with protein misfolding and aggregation, mitochondrial dysfunction, oxidative stress, dysregulated protein homeostasis, neuroinflammation, and disrupted cell death pathways. Recent findings have added disease-specific processes, like amyloid-\u03b2 and tau aggregates in AD, \u03b1-synuclein aggregation and mitophagy failure in PD's, TDP-43-related impaired RNA metabolism in ALS, and mutant huntingtin causing transcription aberrations in HD. Protein interactome network analysis showed mechanistic crosstalk between pathogenic proteins of AD and PD. New evidence highlights how lysosomal dysfunction, endoplasmic reticulum stress, and microglial activation, act as a common axis in neurodegeneration. Advancements in genomics and epigenomics have found shared genetic risk loci and regulatory processes that affect how diseases develop and progress. Simultaneously, new biomarkers like circulating microRNAs, exosome-related pathological proteins, neurofilament light chain, inflammatory cytokines, and microglial activation markers are powering early diagnosis tools and disease variations. New imaging techniques also allow for the identification of protein aggregations before symptoms appear. Overall, these findings are accelerating targeted treatments and personalized medicine aimed at disease progression. This review highlights current insights into the molecular mechanisms of NDs and discusses new biomarkers and treatment targets that help future diagnostic and treatment strategies."

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

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.

Here, we report that the M337V mutation in TDP43 exacerbates its proteotoxicity relative to the wild-type protein. Concurrently, multi-omics analysis revealed a pronounced downregulation of TRIM16 in motor neuron-like cells expressing either wild-type or M337V mutant TDP43. Functional studies demonstrated that TRIM16 overexpression effectively mitigated oxidative stress, restored mitochondrial integrity, and suppressed ferroptosis. Mechanistically, TRIM16 promoted the ubiquitination and degradation of Keap1, thereby facilitating the activation of Nrf2-mediated antioxidant genes. Furthermore, we identified the iron import receptor TFR1 as a novel ubiquitination substrate of TRIM16. TRIM16 mediated the ubiquitination of TFR1 and targeted it for p62-dependent autophagic degradation, which in turn reduced iron accumulation and lipid peroxidation.

Here, we show that psychological stress impairs HSC self-renewal and lymphoid differentiation, inducing aging-like phenotypes. Stress suppresses neuronal activity in the medial prefrontal cortex (mPFC) and periaqueductal gray (PAG), leading to HSC dysfunction, whereas chemogenetic activation of these regions restores HSC function. Psychological stress or chemogenetic inhibition of the mPFC and PAG reduces the abundance of L. reuteri in the gut microbiota and lowers spermidine levels. Mechanistically, spermidine depletion suppresses mitochondrial autophagy, promotes mitochondrial peroxidative stress, and increases ferroptotic stress in HSCs. We further demonstrate that mPFC and PAG activity regulate the intestinal environment through a sympathetic pathway, reducing intestinal mucin levels, L. reuteri abundance, and spermidine levels. These findings identify a brain-gut-bone marrow axis linking psychological stress to aging-like HSC dysfunction through sympathetic regulation of intestinal microbiota and spermidine metabolism."

Here, we investigated the effects of spermidine on lifespan, behavioral responses, brain tissue, target gene expression, and antioxidant status in Drosophila melanogaster model of age-dependent neurodegeneration. Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood. Lifespan analysis revealed that high-dose spermidine (5\u2009mM) reduced survival in both wild-type and sws1 mutants, whereas lower doses (0.5 and 1\u2009mM) significantly improved survival in mutants without affecting wild-type flies. Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations.

However, whether GCGR directly confers renoprotection and the underlying mechanisms remain unclear. Here, using tubule-specific GCGR loss- and gain-of-function mouse models and human kidney samples, we show that tubular GCGR signaling exerts an important renoprotective role in DKD. Tubular GCGR expression is reduced in humans and mice with DKD and correlates with worse kidney function and increased renal injury. Genetic ablation of tubular GCGR markedly exacerbates DKD and induces pronounced phospholipid accumulation within enlarged lysosomes. Mechanistically, GCGR loss disrupts its association with the V-ATPase V1A subunit ATP6V1A, compromises V1-V0 assembly, and thereby impairs lysosomal acidification. This defect leads to impaired phospholipid hydrolysis and protease maturation, blockade of autophagic flux, and ultimately tubular cell injury. In vivo, ATP6V1A overexpression markedly reverses GCGR deficiency-induced lysosomal dysfunction and DKD progression. Consistently, re-expression of tubular GCGR via AAV9 restores lysosomal function, reduces phospholipid accumulation, and mitigates renal injury in DKD. Together, these findings provide genetic evidence for the renoprotective role of tubular GCGR in DKD, delineate a kidney-intrinsic GCGR-ATP6V1A-lysosome axis that protects tubular integrity, and extend prior GCGR-in-kidney observations into a more concrete GCGR-lysosome mechanism."

Although these disorders are often clinically defined by symptoms and affected brain regions, many are mechanistically linked to abnormal protein accumulation, misfolding, impaired proteostasis, RNA dysregulation, mitochondrial dysfunction, and neuroinflammation. In this Perspective article, I discuss major neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, dementia with Lewy bodies, multiple system atrophy, amyotrophic lateral sclerosis, frontotemporal dementia, Huntington's disease, prion diseases, spinocerebellar ataxias, and spinal muscular atrophy, through the lens of disease-associated proteins and experimental modeling. I argue that a protein-centered framework provides a useful approach for understanding disease mechanisms and selecting transgenic mouse models, while recognizing that aging, cellular context, neuroinflammation, mitochondrial dysfunction, vascular dysfunction, and other disease modifiers also shape neurodegeneration. Transgenic and genetically engineered mouse models have been essential for dissecting the pathogenic roles of amyloid-\u03b2, tau, \u03b1-synuclein, TDP-43, SOD1, FUS, C9ORF72-associated dipeptide repeat proteins, mutant huntingtin, prion protein, ataxins, and SMN deficiency. However, these models have important limitations, including artificial overexpression, familial mutation bias, species differences, and incomplete representation of aging-related sporadic diseases. Rather than seeking a single \"best\" model, a more productive strategy is to adopt model portfolios tailored to specific biological questions and to integrate mouse studies with human cellular models, postmortem tissue, omics approaches, and biomarker-based validation. Such an approach may improve mechanistic insight, strengthen translational relevance, and enhance the predictive value of preclinical neurodegenerative disease research."

Here, we defined the lncRNA landscape across iPSC-derived neurons, astrocytes, and microglia harboring the frontotemporal dementia-associated MAPT IVS10+16 mutation and investigated how lncRNA dysregulation interfaces with tau pathology. Transcriptomic analyses revealed extensive cell-type specific lncRNA expression changes, with neurons exhibiting the greatest degree of mutation-associated remodeling. Comparative analyses with MAPT IVS10+16 patient brain tissue identified NORAD and MIR22HG as lncRNAs significantly dysregulated across all three cell types and human brains. NORAD was also altered in Alzheimer's disease and Parkinson's disease brains, suggesting a broader role in neurodegenerative disease. Mechanistically, NORAD-associated protein networks converged on pathways related to RNA regulation, cytoskeletal organization, proteostasis, and tau interaction networks. Given the established role of NORAD in regulating PUM1 and PUM2 RNA-binding (pumilio) proteins, we examined the NORAD-pumilio axis and identified enrichment of pumilio-associated pathways linked to autophagy, endocytosis, proteostasis, and cytoskeletal regulation. NORAD depletion reduced tau seeding and uptake, whereas functional depletion of PUM1 or PUM2 increased both processes, supporting an antagonistic relationship between NORAD and pumilio signaling in modulation of tau aggregation.

Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA."

Hypobaric hypoxia at high altitudes accelerates aging, while D-galactose (D-gal) injection mimics metabolic aging. The gut microbiota is a key regulator of aging, but whether indigenous probiotics from the high plateaus of Tibet exert comparable or differential efficacy against distinct aging etiologies remains unclear. In this study, we systematically evaluated the protective effects of Lactiplantibacillus plantarum AL4510, a novel probiotic strain isolated from traditional fermented goat milk on the Qinghai-Tibet Plateau. We used both D-gal-induced and hypobaric hypoxia-induced aging models established simultaneously within the same experimental system. AL4510 significantly alleviated oxidative stress in both models, as evidenced by restored serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reduced malondialdehyde (MDA) levels. Systemic inflammation was attenuated, with lower interleukin-1\u03b2 (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1) concentrations. Cellular senescence, assessed using senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) and p16 immunofluorescence, was markedly reduced in both liver and colon tissues by approximately 50-60%. The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovibrio, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculum, and Lactobacillus. Metabolomic profiling revealed that AL4510 replenished short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate in both models, indicating restoration of gut fermentative capacity. Importantly, AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4; in the hypoxia model, it upregulated neuroprotective catalpol, lupeol, and energy-related calcium pantothenate. Integrative correlation and co-occurrence network analyses suggested that AL4510 was associated with a beneficial microbial consortium that correlated with host metabolism potentially involving the microbiota-SCFA axis. Collectively, these findings suggest that AL4510 exerts broad spectrum anti-aging effects potentially involving a \"dual-track\" mechanism: convergent restoration of gut ecological balance and divergent, stress-adapted reprogramming of host metabolism. This study provides a scientific basis for developing AL4510 as a functional probiotic ingredient or postbiotic formulation for high-altitude adaptation, metabolic anti-aging interventions, and gut-targeted nutritional strategies."

The C9orf72 repeat expansion is bidirectionally transcribed into sense and anti-sense RNA foci, and also produces dipeptide repeats (DPRs) via a non-canonical translation mechanism known as repeat-associated (RAN) translation. Each of these components of the G4C2 repeat expansion cause neurodegenerative effects in animal models when expressed in neurons, but impacts from glial expression are more poorly understood. Here, we use glial cell type-specific expression of individual DPRs, of RNA repeat-only, or of the G4C2 repeat, that produces both DPRs and RNA repeats, to systematically investigate glial toxicity of each component. We find that as with neurons, the GR and G4C2 transgenes produce the highest degree of toxicity when expressed in glia. Each of these transgenes are capable to produce the GR DPR, which also is the most toxic factor in neurons. We demonstrate that both the GR and G4C2 transgenes cause activation of mdg4, an endogenous retrovirus (ERV). Such ERV expression is a hallmark of TDP-43 dysfunction that is commonly observed in C9orf72 patients. We find that glial expression of either the GR or the G4C2 transgene is toxic to glial cells, but such expression does not cause loss nearby neurons. However, blocking apoptotic signaling within glia that express either GR or G4C2 via expression of the p35 caspase inhibitor further exacerbates effects on lifespan and ablating such glia via expression of the proapoptotic reaper gene partially ameliorates these effects. Together, these results indicate that expression of toxic C9orf72 components in glia produces deleterious effects on lifespan, though potentially through different mechanisms than seen in TDP-43 models of ALS/FTD."

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."

This study aimed to elucidate the protective effect of agmatine (AGM) on sepsis-induced intestinal injury and its mitochondrial-targeted antiapoptotic mechanism in intestinal epithelial cells (IECs). We verified the transport and subcellular localization of AGM in IECs via fluorescence assays and established in vitro and in vivo IEC apoptosis models. Functional evaluations using cell viability assays, laser confocal imaging, flow cytometry, transmission electron microscopy, and multiomics techniques were performed. AGM attenuated sepsis-induced intestinal injury, as evidenced by its ability to lower the serum levels of intestinal damage markers in septic mice, attenuate inflammatory factor production and pathological damage in the intestine, and reduce IEC apoptosis. AGM entered IECs via the polyamine transport system (PTS), but not the NMDA receptor, and inhibited IEC apoptosis induced by TNF\u03b1/CHX or TNF\u03b1/ActD. Notably, AGM exerted its antiapoptotic effect by targeting the mitochondrial imidazoline I2 receptor (I2R). Mechanistically, AGM induced mitophagy by decreasing the mitochondrial membrane potential without altering mitochondrial number or function, as ROS production, calcium ion influx, ATP generation, and oxygen consumption were unchanged. AGM also increased autophagic flux, as confirmed upon treatment with various autophagy inhibitors. AGM alleviates sepsis-induced intestinal injury via the PTS-I2R axis by promoting mitophagy and autophagic flux to inhibit IEC apoptosis, laying a foundation for the use of AGM as a potential nutritional supplement or therapeutic agent for sepsis-induced intestinal injury."

IL17A (interleukin 17A), a proinflammatory cytokine primarily secreted by Th17 and \u03b3\u03b4 T cells, has been implicated in immune-mediated neurodegeneration. However, the role of IL17A in the pathogenesis of HD remains poorly understood. Here, we identify IL17A as a critical pathogenic factor in HD that promotes neuroinflammation, mHTT aggregation, and autophagy-lysosomal dysfunction. IL17A disrupts autophagic flux by downregulating CTSB and CTSD, inducing SQSTM1/p62 and MAP1LC3B-II/LC3-II accumulation, and impairing lysosomal reformation. Mechanistically, IL17A suppresses lysosomal biogenesis by inhibiting the nuclear translocation of TFE3. This regulation occurs via a novel GSK3B/GSK-3\u03b2-TFE3 signaling pathway. Therapeutic neutralization of IL17A with a monoclonal antibody (IL17A mAb) ameliorates disease phenotypes in R6/2 HD mice, improving motor performance, extending survival, and reducing gliosis. IL17A mAb also attenuates mHTT aggregation and enhances neuroprotective signaling, as evidenced by increased expression of DLG4/PSD-95, phosphorylated CREB1, and BDNF. Moreover, IL17A mAb restores autophagy-lysosomal function by facilitating the clearance of protein aggregates and upregulating lysosomal enzymes and biogenesis markers, including CTSB, CTSD, PIP5K1A, and LAMP2. These findings establish IL17A as a key modulator of HD pathophysiology and highlight IL17A inhibition as a promising therapeutic strategy for targeting autophagy-lysosomal dysfunction in HD."

A structured narrative review of the literature was conducted using PubMed/MEDLINE up to March 2025. Relevant studies including clinical trials, observational studies, mechanistic research, and reviews were selected to summarise the molecular mechanisms and cardiovascular effects of HCQ. HCQ exerts multiple beneficial cardiovascular effects through anti-inflammatory, antithrombotic, metabolic, and endothelial-protective mechanisms. It reduces cytokine production, oxidative stress, platelet activation, and improves lipid and glucose profiles, contributing to decreased cardiovascular risk in patients with systemic autoimmune diseases. However, HCQ may also induce cardiotoxic effects, particularly with long-term use or high cumulative doses. These include QT interval prolongation, conduction abnormalities, and a rare but severe form of cardiomyopathy related to lysosomal dysfunction and impaired autophagy. The risk is higher in patients with advanced age, renal dysfunction, pre-existing heart disease, or concomitant use of QT-prolonging drugs. HCQ has a complex and context-dependent cardiovascular profile. While generally cardioprotective at standard doses, it may lead to rare but serious cardiac adverse effects in highrisk patients. A risk-adapted monitoring strategy is essential to optimise its benefit-risk balance in clinical practice."

While genetic studies have linked ANXA11 mutations (e.g., D40G) to disease, the precise molecular events converting aggregation into neurotoxicity and intercellular propagation remain elusive. We hypothesize that lysosomal integrity serves as a critical checkpoint in ANXA11 proteinopathy and that its failure drives disease progression. To model the human pathology of ANXA11, we generated pre-formed fibrils (PFFs) of wild-type and FTLD/ALS-linked D40G mutant ANXA11. Human iPSC-derived neurons, 3D cerebral organoids, and bulk RNA-sequencing were employed to investigate neurotoxicity. High-resolution imaging, lentiviral knockdown, and biochemical assays were performed to delineate the lysosomal damage response and the subsequent \"prion-like\" spreading of aggregates. The internalized ANXA11 fibrils accumulated in lysosomes, triggering lysosomal membrane permeabilization (LMP). The D40G mutation exacerbated this toxicity, leading to severe LMP, mitochondrial depolarization, and specific transcriptional downregulation of the dynactin subunit ACTR10. Mechanistically, we identified a protective signaling axis involving p38 MAPK, MK2, and HSP27 that senses ANXA11-induced lysosomal damage and initiates lysophagy. Notably, in human cerebral organoids, failure of this lysophagic clearance facilitated the cytoplasmic escape of ANXA11, thereby accelerating its seeding activity and propagation to neighboring cells. Pharmacological or genetic modulation of this pathway significantly altered neuronal survival. Our study established lysosomal rupture as a primary driver of ANXA11-associated neurodegeneration and validated the p38/MK2/HSP27 axis as a crucial defense mechanism in human neural tissue. These findings provide a novel mechanistic link between lysosomal quality control and ANXA11 propagation, highlighting that enhancing lysophagic flux represents a promising translational strategy to halt the progression of FTLD and ALS."

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.

While amyloid-\u03b2 and tau have long been established as cardinal pathological hallmarks, growing evidence delineates TDP-43 as a critical participant of neurodegeneration, intricately interwoven with amyloid and tau pathologies. TDP-43 mislocalization, post-translational modifications, and aggregation potentiate neuronal loss through disruption of RNA metabolism, nucleocytoplasmic transport, and protein homeostasis. This tripartite interplay manifests in synergistic and possibly multidirectional pathological cascades that amplify neuronal vulnerability and cognitive decline, thereby complicating the clinical and pathological complexity of AD. Here, we critically reviewed the mechanistic crosstalk among TDP-43, amyloid-\u03b2, and tau, focusing on preclinical and clinical evidence, highlighting possible convergent pathways of aggregation, propagation, and neurodegeneration. Moreover, this review also evaluates mitochondrial dysfunction, autophagy failure, and inflammation as underlying events associated with TDP-43 pathology. Therefore, we argue for a reconceptualization of AD as a dynamic proteinopathy network, with TDP-43 as a core integrative node influencing disease onset and its progression. Notably, we discuss emerging diagnostic modalities associated with molecular tracers of TDP-43, providing prospects for future biomarker identification. Finally, this review articulates the translational relevance of TDP-43 therapy in AD and related neurological disorders, emphasizing the necessity of holistic approaches that transcend the traditional amyloid-tau paradigm to effectively tackle the full spectrum of AD pathobiology."

Chronic exposure to HGA promotes oxidative stress, chondroptosis, secondary amyloidosis, and impaired autophagy, an essential process for maintaining chondrocyte homeostasis. This study investigated the mechanisms potentially involved in autophagy dysregulation in AKU using the human C20/A4 chondrocyte line treated with 0.1 mM HGA, an established in vitro model of the disease. The findings were then verified using chondrocyte cells and cartilage tissue obtained from AKU biopsies. HGA treatment induced a time-dependent increase in oxidative stress, evidenced by elevated ROS levels, 4-HNE accumulation, and overproduction of mitochondrial superoxide. Autophagy assessment showed an early increase in autophagy-related markers, with increased LC3 and p62 expression and enhanced lysosomal biogenesis (LAMP1). However, prolonged HGA exposure was associated with reduced LC3/LAMP1 colocalization, persistent p62 accumulation, altered acidic compartment staining, and accumulation of autophagy-related structures, supporting a dysregulation of the autophagy-lysosomal pathway. Live-cell imaging further supported a transition from functional autophagy to lysosomal failure under chronic oxidative stress. Overall, this study suggests that prolonged HGA exposure disrupts the interplay between oxidative stress and autophagic flux. The progressive collapse of these adaptive mechanisms may contribute to chondrocyte degeneration and to the pathogenesis of cartilage damage in AKU."

Therapeutic strategies targeting aging hallmarks can delay aging and mitigate disease risk. Emerging interventions focus on modulating core aging mechanisms, including cellular senescence, metabolic dysfunction, epigenetic alterations, and mitochondrial impairment, etc. Recent advances have focused on three strategies: senolytics (eliminating senescent cells, e.g., dasatinib + quercetin), senomorphics (inhibiting the senescence-associated secretory phenotype, e.g., rapamycin), and senoreversion (rejuvenating senescent cells via epigenetic reprogramming). Additionally, metabolic interventions such as caloric restriction mimetics (e.g., spermidine, \u03b1-ketoglutarate, ergothioneine) enhance mitochondrial function, activate autophagy, and reprogram energy metabolism, demonstrating lifespan extension and healthspan improvement in preclinical models. Collectively, these approaches hold promise for delaying aging and alleviating age-related pathologies, facilitating the transition to precision longevity medicine.

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

Emerging evidence suggests that intracellular zinc dynamics regulate lysosomal function by modulating processes such as acidification and lysosomal biogenesis. We previously identified 1H10 as an AMP-activated protein kinase (AMPK) inhibitor and subsequently demonstrated its zinc-binding capacity and ability to regulate intracellular zinc homeostasis. Building on our prior findings that intra-lysosomal zinc promotes acidification and activates transcription factor EB (TFEB), we investigated whether 1H10 enhances lysosomal function through zinc mobilization in neurons, thereby improving autophagy and reducing pathological protein accumulation. In primary cortical neurons, 1H10 increased lysosomal abundance and enhanced lysosomal degradative capacity in a zinc-dependent manner, as demonstrated by increased cathepsin B activity and DQ-BSA degradation. It alleviated lysosomal dysfunction induced by v-ATPase inhibition and promoted autophagic flux, leading to reduced accumulation of amyloid-\u03b2 (A\u03b2) and tau in neuronal models. In 5XFAD mice, 1H10 treatment showed trends toward improved spatial learning in the Morris water maze, reduced tau phosphorylation at Thr205 and Ser214, normalized LC3-II levels, and restored autophagic-lysosomal homeostasis, without significant changes in extracellular amyloid plaque burden. These findings indicate that zinc-mediated lysosomal activation by 1H10 enhances the autophagy-lysosomal pathway and attenuates tau pathology in AD models, suggesting that targeting lysosomal function may represent a potential therapeutic strategy for neurodegenerative disorders characterized by impaired proteostasis."

Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS."

Its acetyl group enables transport via monocarboxylate transporters, supporting blood-brain barrier penetration and efficient cellular uptake. Inside cells, levacetylleucine is metabolised by acylases, generating elevated levels of L-leucine that enhance mitochondrial bioenergetics and is thought to ameliorate lysosomal dysfunction indirectly. Here, we describe a direct effect of levacetylleucine on lysosomal regulation through modulation of TFEB, the master transcription factor for lysosomal and autophagy genes. Levacetylleucine rapidly alters TFEB translocation between the cytoplasm and the nucleus in a biphasic, homeostasis-restoring manner. In wild-type HeLa cells, levacetylleucine promotes TFEB activation and nuclear localisation. However, in NPC1 disease models, where we show that TFEB is over-activated and enriched in the nucleus due to lysosomal stress, levacetylleucine reduces nuclear TFEB and restores a more normal cytoplasmic-to-nuclear balance. These effects occur at clinically relevant concentrations associated with lysosomal storage reduction. The effects of the drug are stereospecific: while the L-enantiomer is active, the D-enantiomer and racemate show no effect, revealing the antagonistic properties of the D-enantiomer. This bidirectional normalisation of TFEB activity highlights a direct mechanism through which levacetylleucine modulates lysosomal and autophagic pathways in the HeLa cell model, giving mechanistic insight into its therapeutic potential in NPC, and also across diverse neurological and neurodevelopmental disorders."

Its dynamic function is closely intertwined with lipid metabolism, forming an integrated regulatory network termed the endo-lysosomal-lipid axis. Disruption of this axis can impair endosomal maturation, lysosomal acidification, autophagic degradation, and lysosome-centered signaling pathways, resulting in defective cellular clearance and chronic inflammatory responses. Conversely, dysfunction of the endo-lysosomal system disrupts cholesterol trafficking, lipid redistribution, and macromolecular degradation, ultimately promoting secondary lipid accumulation and metabolic imbalance. In this review, we summarize the reciprocal interactions between lipid metabolism and endo-lysosomal function, with particular emphasis on membrane trafficking, lysosomal homeostasis, autophagy, membrane contact sites, and multicellular lipid clearance networks. We further discuss how these interconnected processes contribute to disease progression and highlight emerging therapeutic strategies aimed at restoring lysosomal function and lipid homeostasis. Understanding the dynamic regulation of the endo-lysosomal-lipid axis may provide new mechanistic insights into metabolic and neurodegenerative disorders and identify novel therapeutic opportunities."

To gain insight into these, we screen for cytoplasmic interactors of well-known receptors in mouse pancreatic ductal adenocarcinoma cells. Our data subsequently reveal a non-canonical action of PRKAR1A, a subunit of protein kinase A (PKA), in binding and activating FAM134B/C. At a molecular level, an amphipathic helix in the otherwise-disordered C terminus of FAM134B directly binds PRKAR1A dimers. Multimodal imaging reveals that this interaction occurs at interorganellar contact sites between the ER and liquid-like condensates of PRKAR1A. Mechanistically, ER-condensate contacts promote clustering of FAM134B/C with LC3B and recruit lysosomes, forming degradation hubs. Unexpectedly, these structures are found to control cytoplasmic signaling through FAM134B/C-mediated lysosomal sequestration of RhoA. Underscoring the physiologic relevance of this, these cytoplasmic-facing actions of FAM134B/C result in RhoA-dependent cell morphologic and migratory control in response to cyclic AMP (cAMP) stimuli.

However, most studies in NMR cells have relied on static biochemical or ultrastructural readouts, leaving the dynamic organisation of autophagy in living cells poorly defined. Here, we establish a stable tandem fluorescent autophagy reporter in NMR skin fibroblasts using an mCherry-EGFP-LC3NMR construct to enable live-cell, single-cell resolution analysis of ALP dynamics. Under basal conditions, NMR skin fibroblasts exhibit a greater abundance of LC3-positive structures than HeLa cells, together with a mixed population of autophagosomes and autolysosomes, indicating a distinct steady-state organisation of the ALP. Chloroquine (CQ)-induced lysosomal stress caused the expected accumulation of LC3-positive structures but also triggered the formation of large cytoplasmic vacuoles in NMR skin fibroblasts. Importantly, this vacuolation was not associated with acute cytotoxicity and progressively resolved following CQ removal, accompanied by reorganisation of LC3-positive compartments and recovery of lysosomal acidity. Electron microscopy showed that CQ-induced vacuoles are membrane-bound, containing internal material and co-existing with multiple ALP-related vesicular compartments. Primary NMR skin fibroblasts display a similar vacuolation phenotype, indicating that this response is not an artefact of immortalisation or reporter expression. Together, these findings establish a live-cell platform for analysing autophagy in NMR cells and identify a distinctive, reversible vacuolation response to lysosomal stress, consistent with dynamic remodelling of the lysosomal system within NMR skin fibroblasts."

Pathophysiological conditions in the cell cause the protein quality control system to depend on the autophagy-lysosome pathway (ALP) for degradation of accumulated misfolded proteins and mitochondrial turnover. BCL2-associated athanogene 3 (BAG3) protein has a role in initiating the ALP. Our aim was to ameliorate disease processes resulting from mitochondrial abnormalities and misfolded protein aggregation by upregulating the ALP through overexpression of human BAG3 (hBAG3). The VCP-A232E mouse, a model for hIBM, received AAVrh74.tMCK.hBAG3 systemically at 3 months of age, and outcome measures, including functional, histological, and molecular studies, were assessed 9 months post-gene delivery. hBAG3 treatment improved treadmill running distance and rotarod duration, reduced the number of TDP-43-positive aggregates, and decreased the number of fibers showing abnormalities in mitochondrial enzyme histochemistry, compared with the untreated cohort. Moreover, hBAG3 gene therapy resulted in improvements in mitophagy and mitochondrial homeostasis observed as increased levels in mitophagy markers Parkin and Bnip3, mitochondria biogenesis marker Pgc1\u03b1 and mitochondrial DNA-encoded subunits of complex IV, Cox1 and Cox3. In addition, the LC-II/I ratio increased, indicating increased autophagic flux. Our study presents evidence that the strategy of supporting the ALP system by overexpressing BAG3 has potential therapeutic use for myodegenerative conditions associated with abnormal protein aggregates and mitochondrial turnover."

Genetic studies, including genome-wide association studies, have identified variants in BAG3, a key regulator of protein quality control (PQC), as contributors to both familial and sporadic forms of DCM. Impaired PQC and the accumulation of misfolded proteins (proteinopathy) have emerged as potential pathogenic mechanisms. Here, we investigated the molecular consequences of a recently identified BAG3 missense variant (V468\u202fM) associated with familial DCM. To assess the in vivo effects of the variant, human BAG3V468M was ectopically expressed in wild-type zebrafish embryos. Overexpression of BAG3V468M resulted in a DCM-like phenotype characterized by ventricular dilation, reduced heart rate, and impaired contractility. Transmission electron microscopy revealed marked disruption of myocardial ultrastructure and sarcomeric organization. To explore the impact on proteostasis, markers of autophagy (LC3-I/II and p62) were analyzed and showed no significant differences between BAG3V468M and control embryos under basal conditions. In contrast, analysis of the ubiquitin-proteasome system demonstrated a significant accumulation of ubiquitinated proteins in BAG3V468M-expressing embryos, suggesting impaired proteasomal protein clearance or increased proteotoxic stress. Expression of BAG3V468M induces a DCM-like phenotype in vivo associated with disrupted myocardial architecture and altered proteostasis. While canonical autophagy markers remain unchanged, the accumulation of ubiquitinated proteins points toward a disturbance in ubiquitin-mediated protein turnover. These findings implicate mutation-specific alterations in proteostasis as a potential mechanism contributing to BAG3-associated cardiomyopathy."

Limiting the damage caused by MIR is crucial but is still an unmet clinical need because of the complexity of the underlying mechanisms. Increasing evidence suggests that lysosomal autophagy plays a significant regulatory role in MIR injury. The specific mechanisms involved remain to be fully understood. We here systematically analyzed the murine MIR model database to screen the potentially protective lysosome-localized proteins against MIR injury. The positive hits were further functionally screened and validated for their capability on autophagy and hypoxia/reoxygenation insults of cardiomyocytes. After exploring the detailed molecular mechanism underlying the protective effects of the target protein, we generated target gene cardiac-specific knockout mice and overexpression mice to verify its function in mouse MIR injury models. LAPTM4A (lysosome-associated protein transmembrane 4 alpha) stood out as a significant protective lysosome-localized protein from the screening. LAPTM4A deficiency significantly heightened the inflammatory response and cell death both in primary cardiomyocytes and in a MIR-induced mouse model. Conversely, LAPTM4A overexpression exerted protective effects on cell viability and myocardial damage. Mechanistically, LAPTM4A interacts with Rubicon (Run domain Beclin1-interacting and cysteine-rich domain-containing protein), hindering its engagement within the Beclin1 complex, resulting in a robust augmentation of autophagic flux and thereby mitigating cardiac damage during reperfusion. It is important to note that Rubicon knockdown markedly reversed the aggravated injury induced by LAPTM4A knockdown, further verifying the effects of LAPTM4A depend on Rubicon. Our findings screened out and validated that LAPTM4A is a lysosome-localized protein exerting protective effects against MIR injury by facilitating autophagic flux. Targeting LAPTM4A represents a promising therapeutic strategy for mitigating MIR injury."

However, disease-modifying therapies targeting this pathway remain unavailable. Here, we generated induced pluripotent stem cells (iPSCs) from a PARK9 patient carrying an ATP13A2 mutation and established mutation-corrected isogenic control iPSCs. PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification, reduced mature cathepsin D levels, CD63-positive vesicle accumulation, LC3B-positive autophagosome accumulation, cytoplasmic pSer129 \u03b1-synuclein accumulation, and increased cleaved caspase-3 signals. These phenotypes were ameliorated in mutation-corrected neurons, supporting the contribution of ATP13A2 dysfunction to these abnormalities. We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation. Among these, paroxetine, Ro 25-6981, amisulpride, and PK11195 showed additional, compound-dependent effects on PARK9-associated phenotypes, including lysosomal acidification, CD63-positive vesicle accumulation, cytoplasmic pSer129 \u03b1-synuclein signals, and cleaved caspase-3 signals. These findings establish PARK9 iPSC-derived neurons as a useful model of lysosomal dysfunction-associated PD pathology and provide a practical screening platform for identifying candidate compounds that modulate autophagy-lysosome pathway-related cellular phenotypes."

Herein, a sustainable synthetic strategy is presented for benzothiazole-modified carbon dots (LysoDots), engineered for specific lysosome localization and viscosity monitoring. LysoDots display a viscosity-dependent fluorescence enhancement in glycerol-water systems while remaining insensitive to physiological pH and temperature variations. This turn-on response allows for the high-fidelity tracking of lysosomal microviscosity changes induced by exogenous stimuli, such as nystatin, and endogenous processes like rapamycin-induced autophagy. Confocal imaging demonstrates a remarkable colocalization of LysoDots with the commercial lysosome marker, LysoTracker Green (LTG), showing a Pearson's correlation coefficient of 0.92 in CAL-33 oral carcinoma cells, with the red emission effectively differentiating lysosomal viscosity profiles between cancerous and non-cancerous cells. Furthermore, the LysoDots were successfully employed in a neuronal model, SH-SY5Y cells, where the probe effectively tracked glutamate-induced lysosomal dysfunction, mimicking the pathology of lysosomal storage disorders, along with the viscosity restoration mediated by trehalose.

This narrative review examines four mechanistically distinct compounds, namely spermidine, fisetin, berberine, and urolithin A, as emerging functional food ingredients with scientifically supported effects on key hallmarks of human aging. Spermidine, a dietary polyamine from wheat germ and fermented foods, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Fisetin, a flavonoid from strawberries and apples, exerts senolytic activity by selectively eliminating senescent cells via PI3K/AKT and Bcl-2/Bcl-xL inhibition, with emerging clinical evidence. Berberine, an isoquinoline alkaloid from Berberis species, modulates metabolic dysfunction via AMP-activated protein kinase (AMPK) activation and reshapes gut microbiota composition through direct high intraluminal exposure, with the most extensive clinical dataset of the four compounds. Urolithin A, a gut microbiome-derived postbiotic from ellagitannins in pomegranates and nuts, induces mitophagy via PINK1/Parkin and has been evaluated in a growing number of registered human clinical trials. Together, the four compounds primarily target distinct but complementary aging-associated pathways (autophagy, senolysis, metabolic regulation, mitophagy), suggesting rational potential for combined functional food formulations. Limited direct evidence for their combined use and the need for dedicated co-administration studies are discussed, alongside bioavailability, safety, and regulatory considerations."

As geroscience increasingly prioritizes healthspan over lifespan, nutritional interventions targeting multiple aging mechanisms have gained attention as accessible strategies to mitigate age-related functional decline. This mini review synthesizes recent evidence on how the bioactivities of two food-derived geroprotective compounds, pyrroloquinoline quinone (PQQ) and spermidine (SPD), intersect with the hallmarks of aging and their distinct and overlapping roles in maintaining cellular homeostasis. PQQ primarily functions as a mitochondrial and redox regulator, enhancing mitochondrial biogenesis and bioenergetic capacity through the AMP-activated protein kinase (AMPK) and sirtuin1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator 1-alpha pathways. In contrast, SPD acts as a key regulator of cellular quality control by inducing macroautophagy and preserving proteostasis, largely through modulation of histone and autophagy-related protein acetylation. These complementary mechanisms converge on several key hallmarks of aging, including genomic instability, deregulated nutrient sensing, mitochondrial dysfunction, and chronic inflammation. The anti-aging mechanisms of PQQ and SPD originate from distinct upstream biochemical processes but converge on shared signaling hubs, including the AMPK/SIRT1 axis and autophagy-related networks. This convergence suggests a coordinated network-level complementarity that may offer a more robust intervention against age-related decline than targeting independent pathways alone."

Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration.

Although these disorders have different clinical features which affect cognition, movement and other vital body functions, they share key underlying molecular and cellular processes. This starts with protein misfolding and aggregation, mitochondrial dysfunction, oxidative stress, dysregulated protein homeostasis, neuroinflammation, and disrupted cell death pathways. Recent findings have added disease-specific processes, like amyloid-\u03b2 and tau aggregates in AD, \u03b1-synuclein aggregation and mitophagy failure in PD's, TDP-43-related impaired RNA metabolism in ALS, and mutant huntingtin causing transcription aberrations in HD. Protein interactome network analysis showed mechanistic crosstalk between pathogenic proteins of AD and PD. New evidence highlights how lysosomal dysfunction, endoplasmic reticulum stress, and microglial activation, act as a common axis in neurodegeneration. Advancements in genomics and epigenomics have found shared genetic risk loci and regulatory processes that affect how diseases develop and progress. Simultaneously, new biomarkers like circulating microRNAs, exosome-related pathological proteins, neurofilament light chain, inflammatory cytokines, and microglial activation markers are powering early diagnosis tools and disease variations. New imaging techniques also allow for the identification of protein aggregations before symptoms appear. Overall, these findings are accelerating targeted treatments and personalized medicine aimed at disease progression. This review highlights current insights into the molecular mechanisms of NDs and discusses new biomarkers and treatment targets that help future diagnostic and treatment strategies."

Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA."

Haploinsufficiency of C9orf72, the most frequently mutated gene in\u00a0amyotrophic lateral sclerosis and frontotemporal dementia, has been linked to autophagy-lysosomal pathway defects, but the role\u00a0of C9orf72 in microglia remains unclear. Here, we identify the C9orf72/SMCR8 complex as a key regulator of microglial homeostasis through promoting lysosomal membrane repair. Loss of C9orf72 and SMCR8 in mice causes age\u2011dependent neuroinflammation and microgliosis, with microglia adopting a disease-associated state. In aged brain and spinal cord tissue, microglia display lysosomal damage marked by galectin\u20113 accumulation. Using a lysosomotropic agent to induce lysosomal damage in microglia, we find that C9orf72/SMCR8-deficient cells accumulate damaged lysosomes and show defective recruitment of phosphorylated RAB8A and the Endosomal Sorting Complexes Required for Transport (ESCRT) machinery\u00a0to damaged lysosomes. Notably, mutant microglia accumulate GTP\u2011bound RAB8A, which becomes hyperphosphorylated and mislocalized to RAB7-positive, LAMP1-negative vesicles. The GTPase-activating activity of the C9orf72/SMCR8 complex is essential for lysosomal repair.

We reanalysed the Genetic and Epigenetic Signatures of Translational Ageing Laboratory Testing(GESTALT) paired RNA sequencing (RNA-seq) and tandem mass tag (TMT) proteome from 82 donors (aged 22-89) using Data Integration Analysis for Biomarker discovery using Latent cOmponents (DIABLO) for supervised multi-omics integration, weighted gene co-expression network analysis (WGCNA), external Genotype-Tissue Expression(GTEx) transcriptomic comparison, network medicine proximity mapping and CDOCKER molecular docking. Three analyses converged on the autophagy-lysosome axis: Kyoto Encyclopaedia of Genes and Genomes (KEGG) Lysosome ranked first in discordant-quadrant analysis; gene set enrichment analysis (GSEA) identified vacuole organisation and macroautophagy as the top age-upregulated Gene Ontology (GO) terms; and WGCNA recovered KEGG Lysosome in the brown module. Module regression localised most proteomic age signals to the lysosomal degradative-capacity module, whereas the proteasome was unaffected. McNemar testing and GTEx comparison supported a protein-side, post-transcriptional origin. TCIRG1, CTSA and ATP6V0D1 were recurrent hubs. Network proximity computationally prioritised hydroxytyrosol as a lysosomal-degradative-capacity-preferential candidate, and CDOCKER on cathepsin A linked its advantage over tyrosol to an ortho-hydroxyl group forming additional hydrogen bonds.

Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy.

Recent publications have demonstrated an inverse relationship between ApoM and clinical outcomes in chronic kidney disease and its concomitant cardiovascular indications. Mechanistic studies show that ApoM's regulation of mitochondrial function and autophagy are likely contributors to this effect. Additionally, ApoA-I, serum amyloid albumin (SAA), and SR-B1 have recently been highlighted as key regulators of atherogenesis through their ability to prevent LDL transcytosis and arterial entrapment by proteoglycans.

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

Here, we show that psychological stress impairs HSC self-renewal and lymphoid differentiation, inducing aging-like phenotypes. Stress suppresses neuronal activity in the medial prefrontal cortex (mPFC) and periaqueductal gray (PAG), leading to HSC dysfunction, whereas chemogenetic activation of these regions restores HSC function. Psychological stress or chemogenetic inhibition of the mPFC and PAG reduces the abundance of L. reuteri in the gut microbiota and lowers spermidine levels. Mechanistically, spermidine depletion suppresses mitochondrial autophagy, promotes mitochondrial peroxidative stress, and increases ferroptotic stress in HSCs. We further demonstrate that mPFC and PAG activity regulate the intestinal environment through a sympathetic pathway, reducing intestinal mucin levels, L. reuteri abundance, and spermidine levels. These findings identify a brain-gut-bone marrow axis linking psychological stress to aging-like HSC dysfunction through sympathetic regulation of intestinal microbiota and spermidine metabolism."

Although the genetic basis of limbic-predominant age-related TDP-43 encephalopathy neuropathologic change remains largely unknown, TMEM106B, GRN and APOE loci are frequently implicated.

Although these disorders are often clinically defined by symptoms and affected brain regions, many are mechanistically linked to abnormal protein accumulation, misfolding, impaired proteostasis, RNA dysregulation, mitochondrial dysfunction, and neuroinflammation. In this Perspective article, I discuss major neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, dementia with Lewy bodies, multiple system atrophy, amyotrophic lateral sclerosis, frontotemporal dementia, Huntington's disease, prion diseases, spinocerebellar ataxias, and spinal muscular atrophy, through the lens of disease-associated proteins and experimental modeling. I argue that a protein-centered framework provides a useful approach for understanding disease mechanisms and selecting transgenic mouse models, while recognizing that aging, cellular context, neuroinflammation, mitochondrial dysfunction, vascular dysfunction, and other disease modifiers also shape neurodegeneration. Transgenic and genetically engineered mouse models have been essential for dissecting the pathogenic roles of amyloid-\u03b2, tau, \u03b1-synuclein, TDP-43, SOD1, FUS, C9ORF72-associated dipeptide repeat proteins, mutant huntingtin, prion protein, ataxins, and SMN deficiency. However, these models have important limitations, including artificial overexpression, familial mutation bias, species differences, and incomplete representation of aging-related sporadic diseases. Rather than seeking a single \"best\" model, a more productive strategy is to adopt model portfolios tailored to specific biological questions and to integrate mouse studies with human cellular models, postmortem tissue, omics approaches, and biomarker-based validation. Such an approach may improve mechanistic insight, strengthen translational relevance, and enhance the predictive value of preclinical neurodegenerative disease research."

Here, we defined the lncRNA landscape across iPSC-derived neurons, astrocytes, and microglia harboring the frontotemporal dementia-associated MAPT IVS10+16 mutation and investigated how lncRNA dysregulation interfaces with tau pathology. Transcriptomic analyses revealed extensive cell-type specific lncRNA expression changes, with neurons exhibiting the greatest degree of mutation-associated remodeling. Comparative analyses with MAPT IVS10+16 patient brain tissue identified NORAD and MIR22HG as lncRNAs significantly dysregulated across all three cell types and human brains. NORAD was also altered in Alzheimer's disease and Parkinson's disease brains, suggesting a broader role in neurodegenerative disease. Mechanistically, NORAD-associated protein networks converged on pathways related to RNA regulation, cytoskeletal organization, proteostasis, and tau interaction networks. Given the established role of NORAD in regulating PUM1 and PUM2 RNA-binding (pumilio) proteins, we examined the NORAD-pumilio axis and identified enrichment of pumilio-associated pathways linked to autophagy, endocytosis, proteostasis, and cytoskeletal regulation. NORAD depletion reduced tau seeding and uptake, whereas functional depletion of PUM1 or PUM2 increased both processes, supporting an antagonistic relationship between NORAD and pumilio signaling in modulation of tau aggregation. Together, these findings identify widespread lncRNA dysregulation across neural cell types in the setting of a MAPT mutation and nominate the NORAD-pumilio axis as a regulatory pathway linking RNA homeostasis and tau propagation biology."

The C9orf72 repeat expansion is bidirectionally transcribed into sense and anti-sense RNA foci, and also produces dipeptide repeats (DPRs) via a non-canonical translation mechanism known as repeat-associated (RAN) translation. Each of these components of the G4C2 repeat expansion cause neurodegenerative effects in animal models when expressed in neurons, but impacts from glial expression are more poorly understood. Here, we use glial cell type-specific expression of individual DPRs, of RNA repeat-only, or of the G4C2 repeat, that produces both DPRs and RNA repeats, to systematically investigate glial toxicity of each component. We find that as with neurons, the GR and G4C2 transgenes produce the highest degree of toxicity when expressed in glia. Each of these transgenes are capable to produce the GR DPR, which also is the most toxic factor in neurons. We demonstrate that both the GR and G4C2 transgenes cause activation of mdg4, an endogenous retrovirus (ERV). Such ERV expression is a hallmark of TDP-43 dysfunction that is commonly observed in C9orf72 patients. We find that glial expression of either the GR or the G4C2 transgene is toxic to glial cells, but such expression does not cause loss nearby neurons. However, blocking apoptotic signaling within glia that express either GR or G4C2 via expression of the p35 caspase inhibitor further exacerbates effects on lifespan and ablating such glia via expression of the proapoptotic reaper gene partially ameliorates these effects. Together, these results indicate that expression of toxic C9orf72 components in glia produces deleterious effects on lifespan, though potentially through different mechanisms than seen in TDP-43 models of ALS/FTD."

As geroscience increasingly prioritizes healthspan over lifespan, nutritional interventions targeting multiple aging mechanisms have gained attention as accessible strategies to mitigate age-related functional decline. This mini review synthesizes recent evidence on how the bioactivities of two food-derived geroprotective compounds, pyrroloquinoline quinone (PQQ) and spermidine (SPD), intersect with the hallmarks of aging and their distinct and overlapping roles in maintaining cellular homeostasis. PQQ primarily functions as a mitochondrial and redox regulator, enhancing mitochondrial biogenesis and bioenergetic capacity through the AMP-activated protein kinase (AMPK) and sirtuin1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator 1-alpha pathways. In contrast, SPD acts as a key regulator of cellular quality control by inducing macroautophagy and preserving proteostasis, largely through modulation of histone and autophagy-related protein acetylation. These complementary mechanisms converge on several key hallmarks of aging, including genomic instability, deregulated nutrient sensing, mitochondrial dysfunction, and chronic inflammation. The anti-aging mechanisms of PQQ and SPD originate from distinct upstream biochemical processes but converge on shared signaling hubs, including the AMPK/SIRT1 axis and autophagy-related networks. This convergence suggests a coordinated network-level complementarity that may offer a more robust intervention against age-related decline than targeting independent pathways alone."

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."

IL17A (interleukin 17A), a proinflammatory cytokine primarily secreted by Th17 and \u03b3\u03b4 T cells, has been implicated in immune-mediated neurodegeneration. However, the role of IL17A in the pathogenesis of HD remains poorly understood. Here, we identify IL17A as a critical pathogenic factor in HD that promotes neuroinflammation, mHTT aggregation, and autophagy-lysosomal dysfunction. IL17A disrupts autophagic flux by downregulating CTSB and CTSD, inducing SQSTM1/p62 and MAP1LC3B-II/LC3-II accumulation, and impairing lysosomal reformation. Mechanistically, IL17A suppresses lysosomal biogenesis by inhibiting the nuclear translocation of TFE3. This regulation occurs via a novel GSK3B/GSK-3\u03b2-TFE3 signaling pathway. Therapeutic neutralization of IL17A with a monoclonal antibody (IL17A mAb) ameliorates disease phenotypes in R6/2 HD mice, improving motor performance, extending survival, and reducing gliosis. IL17A mAb also attenuates mHTT aggregation and enhances neuroprotective signaling, as evidenced by increased expression of DLG4/PSD-95, phosphorylated CREB1, and BDNF. Moreover, IL17A mAb restores autophagy-lysosomal function by facilitating the clearance of protein aggregates and upregulating lysosomal enzymes and biogenesis markers, including CTSB, CTSD, PIP5K1A, and LAMP2. These findings establish IL17A as a key modulator of HD pathophysiology and highlight IL17A inhibition as a promising therapeutic strategy for targeting autophagy-lysosomal dysfunction in HD."

A structured narrative review of the literature was conducted using PubMed/MEDLINE up to March 2025. Relevant studies including clinical trials, observational studies, mechanistic research, and reviews were selected to summarise the molecular mechanisms and cardiovascular effects of HCQ. HCQ exerts multiple beneficial cardiovascular effects through anti-inflammatory, antithrombotic, metabolic, and endothelial-protective mechanisms. It reduces cytokine production, oxidative stress, platelet activation, and improves lipid and glucose profiles, contributing to decreased cardiovascular risk in patients with systemic autoimmune diseases. However, HCQ may also induce cardiotoxic effects, particularly with long-term use or high cumulative doses. These include QT interval prolongation, conduction abnormalities, and a rare but severe form of cardiomyopathy related to lysosomal dysfunction and impaired autophagy. The risk is higher in patients with advanced age, renal dysfunction, pre-existing heart disease, or concomitant use of QT-prolonging drugs. HCQ has a complex and context-dependent cardiovascular profile. While generally cardioprotective at standard doses, it may lead to rare but serious cardiac adverse effects in highrisk patients. A risk-adapted monitoring strategy is essential to optimise its benefit-risk balance in clinical practice."

While genetic studies have linked ANXA11 mutations (e.g., D40G) to disease, the precise molecular events converting aggregation into neurotoxicity and intercellular propagation remain elusive. We hypothesize that lysosomal integrity serves as a critical checkpoint in ANXA11 proteinopathy and that its failure drives disease progression. To model the human pathology of ANXA11, we generated pre-formed fibrils (PFFs) of wild-type and FTLD/ALS-linked D40G mutant ANXA11. Human iPSC-derived neurons, 3D cerebral organoids, and bulk RNA-sequencing were employed to investigate neurotoxicity. High-resolution imaging, lentiviral knockdown, and biochemical assays were performed to delineate the lysosomal damage response and the subsequent \"prion-like\" spreading of aggregates. The internalized ANXA11 fibrils accumulated in lysosomes, triggering lysosomal membrane permeabilization (LMP). The D40G mutation exacerbated this toxicity, leading to severe LMP, mitochondrial depolarization, and specific transcriptional downregulation of the dynactin subunit ACTR10. Mechanistically, we identified a protective signaling axis involving p38 MAPK, MK2, and HSP27 that senses ANXA11-induced lysosomal damage and initiates lysophagy. Notably, in human cerebral organoids, failure of this lysophagic clearance facilitated the cytoplasmic escape of ANXA11, thereby accelerating its seeding activity and propagation to neighboring cells. Pharmacological or genetic modulation of this pathway significantly altered neuronal survival. Our study established lysosomal rupture as a primary driver of ANXA11-associated neurodegeneration and validated the p38/MK2/HSP27 axis as a crucial defense mechanism in human neural tissue. These findings provide a novel mechanistic link between lysosomal quality control and ANXA11 propagation, highlighting that enhancing lysophagic flux represents a promising translational strategy to halt the progression of FTLD and ALS."

While amyloid-\u03b2 and tau have long been established as cardinal pathological hallmarks, growing evidence delineates TDP-43 as a critical participant of neurodegeneration, intricately interwoven with amyloid and tau pathologies. TDP-43 mislocalization, post-translational modifications, and aggregation potentiate neuronal loss through disruption of RNA metabolism, nucleocytoplasmic transport, and protein homeostasis. This tripartite interplay manifests in synergistic and possibly multidirectional pathological cascades that amplify neuronal vulnerability and cognitive decline, thereby complicating the clinical and pathological complexity of AD. Here, we critically reviewed the mechanistic crosstalk among TDP-43, amyloid-\u03b2, and tau, focusing on preclinical and clinical evidence, highlighting possible convergent pathways of aggregation, propagation, and neurodegeneration. Moreover, this review also evaluates mitochondrial dysfunction, autophagy failure, and inflammation as underlying events associated with TDP-43 pathology. Therefore, we argue for a reconceptualization of AD as a dynamic proteinopathy network, with TDP-43 as a core integrative node influencing disease onset and its progression. Notably, we discuss emerging diagnostic modalities associated with molecular tracers of TDP-43, providing prospects for future biomarker identification. Finally, this review articulates the translational relevance of TDP-43 therapy in AD and related neurological disorders, emphasizing the necessity of holistic approaches that transcend the traditional amyloid-tau paradigm to effectively tackle the full spectrum of AD pathobiology."

Chronic exposure to HGA promotes oxidative stress, chondroptosis, secondary amyloidosis, and impaired autophagy, an essential process for maintaining chondrocyte homeostasis. This study investigated the mechanisms potentially involved in autophagy dysregulation in AKU using the human C20/A4 chondrocyte line treated with 0.1 mM HGA, an established in vitro model of the disease. The findings were then verified using chondrocyte cells and cartilage tissue obtained from AKU biopsies. HGA treatment induced a time-dependent increase in oxidative stress, evidenced by elevated ROS levels, 4-HNE accumulation, and overproduction of mitochondrial superoxide. Autophagy assessment showed an early increase in autophagy-related markers, with increased LC3 and p62 expression and enhanced lysosomal biogenesis (LAMP1). However, prolonged HGA exposure was associated with reduced LC3/LAMP1 colocalization, persistent p62 accumulation, altered acidic compartment staining, and accumulation of autophagy-related structures, supporting a dysregulation of the autophagy-lysosomal pathway. Live-cell imaging further supported a transition from functional autophagy to lysosomal failure under chronic oxidative stress. Overall, this study suggests that prolonged HGA exposure disrupts the interplay between oxidative stress and autophagic flux. The progressive collapse of these adaptive mechanisms may contribute to chondrocyte degeneration and to the pathogenesis of cartilage damage in AKU."

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

Its acetyl group enables transport via monocarboxylate transporters, supporting blood-brain barrier penetration and efficient cellular uptake. Inside cells, levacetylleucine is metabolised by acylases, generating elevated levels of L-leucine that enhance mitochondrial bioenergetics and is thought to ameliorate lysosomal dysfunction indirectly. Here, we describe a direct effect of levacetylleucine on lysosomal regulation through modulation of TFEB, the master transcription factor for lysosomal and autophagy genes. Levacetylleucine rapidly alters TFEB translocation between the cytoplasm and the nucleus in a biphasic, homeostasis-restoring manner. In wild-type HeLa cells, levacetylleucine promotes TFEB activation and nuclear localisation. However, in NPC1 disease models, where we show that TFEB is over-activated and enriched in the nucleus due to lysosomal stress, levacetylleucine reduces nuclear TFEB and restores a more normal cytoplasmic-to-nuclear balance. These effects occur at clinically relevant concentrations associated with lysosomal storage reduction. The effects of the drug are stereospecific: while the L-enantiomer is active, the D-enantiomer and racemate show no effect, revealing the antagonistic properties of the D-enantiomer. This bidirectional normalisation of TFEB activity highlights a direct mechanism through which levacetylleucine modulates lysosomal and autophagic pathways in the HeLa cell model, giving mechanistic insight into its therapeutic potential in NPC, and also across diverse neurological and neurodevelopmental disorders."

To gain insight into these, we screen for cytoplasmic interactors of well-known receptors in mouse pancreatic ductal adenocarcinoma cells. Our data subsequently reveal a non-canonical action of PRKAR1A, a subunit of protein kinase A (PKA), in binding and activating FAM134B/C. At a molecular level, an amphipathic helix in the otherwise-disordered C terminus of FAM134B directly binds PRKAR1A dimers. Multimodal imaging reveals that this interaction occurs at interorganellar contact sites between the ER and liquid-like condensates of PRKAR1A. Mechanistically, ER-condensate contacts promote clustering of FAM134B/C with LC3B and recruit lysosomes, forming degradation hubs. Unexpectedly, these structures are found to control cytoplasmic signaling through FAM134B/C-mediated lysosomal sequestration of RhoA. Underscoring the physiologic relevance of this, these cytoplasmic-facing actions of FAM134B/C result in RhoA-dependent cell morphologic and migratory control in response to cyclic AMP (cAMP) stimuli. Thus, interorganellar contacts expand the roles of FAM134B/C ER-phagy receptors beyond ER degradation."

Genetic studies, including genome-wide association studies, have identified variants in BAG3, a key regulator of protein quality control (PQC), as contributors to both familial and sporadic forms of DCM. Impaired PQC and the accumulation of misfolded proteins (proteinopathy) have emerged as potential pathogenic mechanisms. Here, we investigated the molecular consequences of a recently identified BAG3 missense variant (V468\u202fM) associated with familial DCM. To assess the in vivo effects of the variant, human BAG3V468M was ectopically expressed in wild-type zebrafish embryos. Overexpression of BAG3V468M resulted in a DCM-like phenotype characterized by ventricular dilation, reduced heart rate, and impaired contractility. Transmission electron microscopy revealed marked disruption of myocardial ultrastructure and sarcomeric organization. To explore the impact on proteostasis, markers of autophagy (LC3-I/II and p62) were analyzed and showed no significant differences between BAG3V468M and control embryos under basal conditions. In contrast, analysis of the ubiquitin-proteasome system demonstrated a significant accumulation of ubiquitinated proteins in BAG3V468M-expressing embryos, suggesting impaired proteasomal protein clearance or increased proteotoxic stress. Expression of BAG3V468M induces a DCM-like phenotype in vivo associated with disrupted myocardial architecture and altered proteostasis. While canonical autophagy markers remain unchanged, the accumulation of ubiquitinated proteins points toward a disturbance in ubiquitin-mediated protein turnover. These findings implicate mutation-specific alterations in proteostasis as a potential mechanism contributing to BAG3-associated cardiomyopathy."

Limiting the damage caused by MIR is crucial but is still an unmet clinical need because of the complexity of the underlying mechanisms. Increasing evidence suggests that lysosomal autophagy plays a significant regulatory role in MIR injury. The specific mechanisms involved remain to be fully understood. We here systematically analyzed the murine MIR model database to screen the potentially protective lysosome-localized proteins against MIR injury. The positive hits were further functionally screened and validated for their capability on autophagy and hypoxia/reoxygenation insults of cardiomyocytes. After exploring the detailed molecular mechanism underlying the protective effects of the target protein, we generated target gene cardiac-specific knockout mice and overexpression mice to verify its function in mouse MIR injury models. LAPTM4A (lysosome-associated protein transmembrane 4 alpha) stood out as a significant protective lysosome-localized protein from the screening. LAPTM4A deficiency significantly heightened the inflammatory response and cell death both in primary cardiomyocytes and in a MIR-induced mouse model. Conversely, LAPTM4A overexpression exerted protective effects on cell viability and myocardial damage. Mechanistically, LAPTM4A interacts with Rubicon (Run domain Beclin1-interacting and cysteine-rich domain-containing protein), hindering its engagement within the Beclin1 complex, resulting in a robust augmentation of autophagic flux and thereby mitigating cardiac damage during reperfusion. It is important to note that Rubicon knockdown markedly reversed the aggravated injury induced by LAPTM4A knockdown, further verifying the effects of LAPTM4A depend on Rubicon. Our findings screened out and validated that LAPTM4A is a lysosome-localized protein exerting protective effects against MIR injury by facilitating autophagic flux. Targeting LAPTM4A represents a promising therapeutic strategy for mitigating MIR injury."

Alterations in the lysosomal microenvironment serve as an indicator of organelle health and disease progression. Herein, a sustainable synthetic strategy is presented for benzothiazole-modified carbon dots (LysoDots), engineered for specific lysosome localization and viscosity monitoring. LysoDots display a viscosity-dependent fluorescence enhancement in glycerol-water systems while remaining insensitive to physiological pH and temperature variations. This turn-on response allows for the high-fidelity tracking of lysosomal microviscosity changes induced by exogenous stimuli, such as nystatin, and endogenous processes like rapamycin-induced autophagy. Confocal imaging demonstrates a remarkable colocalization of LysoDots with the commercial lysosome marker, LysoTracker Green (LTG), showing a Pearson's correlation coefficient of 0.92 in CAL-33 oral carcinoma cells, with the red emission effectively differentiating lysosomal viscosity profiles between cancerous and non-cancerous cells. Furthermore, the LysoDots were successfully employed in a neuronal model, SH-SY5Y cells, where the probe effectively tracked glutamate-induced lysosomal dysfunction, mimicking the pathology of lysosomal storage disorders, along with the viscosity restoration mediated by trehalose. These findings highlight the potential of LysoDots as a biocompatible, photostable, multi-functional nanomaterial for long-term monitoring of lysosomal dynamics and cellular homeostasis."

IL17A (interleukin 17A), a proinflammatory cytokine primarily secreted by Th17 and \u03b3\u03b4 T cells, has been implicated in immune-mediated neurodegeneration. However, the role of IL17A in the pathogenesis of HD remains poorly understood. Here, we identify IL17A as a critical pathogenic factor in HD that promotes neuroinflammation, mHTT aggregation, and autophagy-lysosomal dysfunction. IL17A disrupts autophagic flux by downregulating CTSB and CTSD, inducing SQSTM1/p62 and MAP1LC3B-II/LC3-II accumulation, and impairing lysosomal reformation. Mechanistically, IL17A suppresses lysosomal biogenesis by inhibiting the nuclear translocation of TFE3. This regulation occurs via a novel GSK3B/GSK-3\u03b2-TFE3 signaling pathway. Therapeutic neutralization of IL17A with a monoclonal antibody (IL17A mAb) ameliorates disease phenotypes in R6/2 HD mice, improving motor performance, extending survival, and reducing gliosis. IL17A mAb also attenuates mHTT aggregation and enhances neuroprotective signaling, as evidenced by increased expression of DLG4/PSD-95, phosphorylated CREB1, and BDNF. Moreover, IL17A mAb restores autophagy-lysosomal function by facilitating the clearance of protein aggregates and upregulating lysosomal enzymes and biogenesis markers, including CTSB, CTSD, PIP5K1A, and LAMP2. These findings establish IL17A as a key modulator of HD pathophysiology and highlight IL17A inhibition as a promising therapeutic strategy for targeting autophagy-lysosomal dysfunction in HD."

The 'protein-as-pathogen' model, where shed viral proteins act as soluble neurotoxins, is now central to understanding this phenomenon. This review presents the opinion that the most critical recent developments are not that these proteins are toxic, but how their mechanisms converge. We synthesize evidence from the last two years showing that proteins from diverse, highly infectious virus families with zoonotic potential (e.g. Coronaviridae, Flaviviridae, Orthomyxoviridae) engage shared host pathways. We focus on two convergent mechanisms: (1) the activation of glial Toll-like receptor (TLR)4/TLR2 signaling, which initiates a chronic neuroinflammatory cascade, and (2) the disruption of host proteostasis, which seeds neurodegenerative proteinopathies like alpha-synuclein and tau aggregation. This framework positions post-viral syndromes as mechanistically related disorders and identifies pan-viral therapeutic targets, such as TLR inhibitors and autophagy activators."

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.

Neuronal injury further promoted the release of damage-associated signals that triggered secondary microglial activations and chronic neuroinflammations.

However, most studies in NMR cells have relied on static biochemical or ultrastructural readouts, leaving the dynamic organisation of autophagy in living cells poorly defined. Here, we establish a stable tandem fluorescent autophagy reporter in NMR skin fibroblasts using an mCherry-EGFP-LC3NMR construct to enable live-cell, single-cell resolution analysis of ALP dynamics. Under basal conditions, NMR skin fibroblasts exhibit a greater abundance of LC3-positive structures than HeLa cells, together with a mixed population of autophagosomes and autolysosomes, indicating a distinct steady-state organisation of the ALP. Chloroquine (CQ)-induced lysosomal stress caused the expected accumulation of LC3-positive structures but also triggered the formation of large cytoplasmic vacuoles in NMR skin fibroblasts. Importantly, this vacuolation was not associated with acute cytotoxicity and progressively resolved following CQ removal, accompanied by reorganisation of LC3-positive compartments and recovery of lysosomal acidity. Electron microscopy showed that CQ-induced vacuoles are membrane-bound, containing internal material and co-existing with multiple ALP-related vesicular compartments. Primary NMR skin fibroblasts display a similar vacuolation phenotype, indicating that this response is not an artefact of immortalisation or reporter expression. Together, these findings establish a live-cell platform for analysing autophagy in NMR cells and identify a distinctive, reversible vacuolation response to lysosomal stress, consistent with dynamic remodelling of the lysosomal system within NMR skin fibroblasts."

However, whether GCGR directly confers renoprotection and the underlying mechanisms remain unclear. Here, using tubule-specific GCGR loss- and gain-of-function mouse models and human kidney samples, we show that tubular GCGR signaling exerts an important renoprotective role in DKD. Tubular GCGR expression is reduced in humans and mice with DKD and correlates with worse kidney function and increased renal injury. Genetic ablation of tubular GCGR markedly exacerbates DKD and induces pronounced phospholipid accumulation within enlarged lysosomes. Mechanistically, GCGR loss disrupts its association with the V-ATPase V1A subunit ATP6V1A, compromises V1-V0 assembly, and thereby impairs lysosomal acidification. This defect leads to impaired phospholipid hydrolysis and protease maturation, blockade of autophagic flux, and ultimately tubular cell injury. In vivo, ATP6V1A overexpression markedly reverses GCGR deficiency-induced lysosomal dysfunction and DKD progression. Consistently, re-expression of tubular GCGR via AAV9 restores lysosomal function, reduces phospholipid accumulation, and mitigates renal injury in DKD. Together, these findings provide genetic evidence for the renoprotective role of tubular GCGR in DKD, delineate a kidney-intrinsic GCGR-ATP6V1A-lysosome axis that protects tubular integrity, and extend prior GCGR-in-kidney observations into a more concrete GCGR-lysosome mechanism."

By screening a V-ATPase-targeted siRNA library and validating the results using publicly available single-cell transcriptomic datasets, we identified ATP6V1A as a key regulator of UVB-induced cellular senescence. Furthermore, ATP6V1A knockdown exacerbated the UVB-induced cellular senescence and impaired lysosomal acidification and membrane integrity, whereas ATP6V1A overexpression effectively alleviated keratinocyte senescence, lysosomal dysfunction and autophagy inhibition. Moreover, treatment with the V-ATPase inhibitor BafA1 aggregated cellular senescence phenotype and autophagy inhibition and this phenomenon partially reversed by ATP6V1A overexpression. Collectively, ATP6V1A promotes autophagy by regulating lysosomal function, thereby relieving UVB-induced cellular senescence."

Progranulin haploinsufficiency, a leading genetic cause of familial FTD, disrupts lysosomal function, lipid metabolism, autophagy, and neuroimmune signaling across multiple cell types. Increasing evidence indicates that microglia are particularly sensitive to progranulin loss, exhibiting elevated complement activation that contributes to TDP-43 proteinopathy and neuronal dysfunction. Here, we investigate the biological role of restoring progranulin exclusively within microglia by transplanting human induced pluripotent stem cell-derived microglial progenitors into progranulin (Grn)-deficient mice. We find that engraftment of wild-type, but not Grn-deficient, human microglia restore brain-wide progranulin levels, normalize microglial transcriptional states, and ameliorate pathological, functional, and behavioral phenotypes associated with progranulin loss. Because human microglia are the only source of progranulin in this system, these findings demonstrate that microglial progranulin is sufficient to restore key aspects of cellular, circuit, and behavioral homeostasis in a progranulin-deficient FTD model. More broadly, this work highlights a central, microglia-intrinsic role for progranulin in maintaining brain function and provides a framework for dissecting microglia-specific mechanisms across FTD and related neurodegenerative disorders."

The clinical course varies widely. Limb weakness, bulbar impairment, respiratory decline, fine-motor dysfunction, cognitive change, mood symptoms, and fatigue may each appear at different times and progress at different rates. This variability suggests that motor neuron loss alone may not fully explain the patient-level pattern of symptoms. This article is a narrative hypothesis framework, not a clinical guideline or a validated stratification tool. Established ALS biology, associative genomic findings, preclinical observations, computational predictions, and author-derived hypotheses are therefore separated throughout the article. This review brings together four interlinked studies by the current author as a primary hypothesis-generating corpus, which proposes that synaptic plasticity fragility may initiate a microglial pruning continuum shared by major depressive disorder and ALS, while ALS-specific progression may depend on mitochondrial stress, oxidized nicotinamide adenine dinucleotide (NAD+) compensation failure, and collapse of autophagy under aging-related limits. The model presented here maps symptom domains to vulnerable circuit compartments and separates three broad biological states: compensated plasticity, fragile plasticity, and network collapse. A compact mechanistic formulation is used to describe the balance between pruning pressure, glutamatergic burden, and aging stress on one side, and oxidative phosphorylation capacity, NAD+ reserve, and autophagic clearance on the other. The framework also incorporates opposing phosphoinositide 3-kinase (PI3K)/AKT/mechanistic target of rapamycin (mTOR) and peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1\u03b1) pathway patterns that may distinguish ALS from frontotemporal dementia (FTD) within an aging context. The result is a falsifiable, biomarker-oriented hypothesis model for future studies, not an evidence-based diagnostic or therapeutic algorithm."

The mitochondrial dysfunction is one of the primary sources of glial activation and dopaminergic neuron loss in Parkinson's disease (PD). The key biochemical elements of the pathogenesis of PD include impaired oxidative phosphorylation, elevated generation of reactive oxygen species (ROS), and impaired mitophagy. This review is a synthesis and stringent evaluation of recent experimental, clinical and genetic studies relating mitochondrial dysfunction and Parkinson's disease (PD). We examined information on bioenergetics, mitochondrial dynamics, calcium homeostasis, and interactions between neurons and glia. The molecular and therapeutic importance of therapies, such as mitophagy modulators, bioenergetic enhancers, and mitochondrial antioxidants, was investigated. The absence of Complex I, excess ROS, mitochondrial DNA damage, and nonfunctioning fusionfission cycles leads to neurodegeneration. The glial metabolic abnormalities worsen the oxidative stress and neuroinflammation, weakening the support of the neurons. The effects of impaired mitophagy are the accumulation of dysfunctional mitochondria, and the effects of calcium overload disrupt energy metabolism. Neuroprotective effects of such substances as spermidine, urolithin A, resveratrol, \u03b1lipoic acid, MitoQ, SkQ1, or CoQ10 have been shown using preclinical research. Sacrifices such as exercising and proper dieting enable the mitochondria to perform better and become stronger. Mitochondrial dysfunction enhances the progression of PD through oxidative stress, bioenergetic breakdown, and inflammatory signalling. Attention to these related systems is an entire way to alter the direction of a disease. PD can be treated using an increase in mitochondrial quality control, redox regulation, and metabolic efficiency. Continued studies in the framework of precision medicine are required to validate the safety and effectiveness of mitochondrial-targeted medications."

Over the past decade, a rapidly expanding literature has identified galectins as regulators of microglial activation, misfolded protein pathology, vesicle damage sensing, autophagy, synaptic plasticity, myelination, vascular repair, and neuroimmune communication. Galectins operate across intracellular and extracellular compartments to integrate cellular stress and innate immune signaling. Here, we review CNS studies of galectin-1, galectin-3, galectin-4, galectin-8, and galectin-9, focusing primarily on work published from 2019 onward while incorporating selected earlier studies to establish foundational concepts. Across experimental models and human studies, galectins orchestrate microglial state transitions, regulate aggregation and propagation of amyloid-\u03b2, tau, \u03b1-synuclein, and mutant huntingtin, and function as intracellular sensors of vesicle and lysosomal damage. Multiple studies further establish galectins as biomarkers and therapeutic targets across Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, stroke, traumatic brain injury, spinal cord injury, retinal degeneration, and chronic pain. Importantly, this review highlights a stage- and context-dependent paradox in which the same galectin axis can amplify neuroinflammation and proteopathic spread in some settings yet support recovery or tissue protection in others. Together, these findings position galectins as central regulators that convert intracellular stress into coordinated neuroimmune programs shaping proteinopathy, circuit dysfunction, and tissue remodeling."

We performed single-nucleus RNA sequencing of frontoinsular cortex, a region affected early in behavioral variant FTD, across individuals with C9orf72-associated and sporadic FTD-MND spectrum disease. By enriching for large projection neurons, we resolved molecular subtypes of layer 5 extratelencephalic neurons, including von Economo neurons, and identified selective depletion of specific layer 2/3 and layer 5 neuron subtypes, convergent across genotypes. Despite selective neuronal loss, disease-associated transcriptional changes were convergent across excitatory neuron populations, suggesting that they reflect upstream pathophysiology or shared responses to local neurodegeneration. By relating neighborhood-level depletion in disease to gene expression in controls, we found that baseline cellular respiration and ATP synthesis predict neuronal vulnerability in disease. These findings define molecular correlates of selective neuronal vulnerability in FTD and provide a framework linking cell type and state to neurodegeneration."

An emerging transcriptomic process that is also increasingly implicated in brain aging, neuroinflammation, and disease is the dysregulation of transposable elements (TEs), repetitive genomic sequences with the potential to cause cellular stress/dysfunction. However, there are limited data on microglial TE transcript patterns in these contexts. Here, we analyzed multiple RNA-seq datasets from isolated human and mouse microglia across aging, Alzheimer's disease (AD), and AD-associated pathology. In contrast to previous observations based on whole-brain tissue and other brain cell types, we found that microglial TE transcript levels remained relatively consistent throughout most of the human lifespan before increasing in late life. We also found that TE transcript levels in microglia from AD patients showed minimal changes compared to age-matched controls, and in RNA-seq analyses of transgenic AD mouse models we observed pathology-associated TE transcript decreases. Subsequent analyses identified inverse associations between TE transcript levels and autophagy/lysosome-related gene expression, and in\u00a0vitro studies suggested that aging- and AD-relevant stimuli, as well as pharmacological autophagy inhibition, modulate TE transcript expression in cultured human microglia. Together, these data provide novel insight into TE transcript dynamics in microglia, highlighting TE transcript patterns that differ from those observed in whole-brain samples and other cell types in aging and AD."

This narrative review examines four mechanistically distinct compounds, namely spermidine, fisetin, berberine, and urolithin A, as emerging functional food ingredients with scientifically supported effects on key hallmarks of human aging. Spermidine, a dietary polyamine from wheat germ and fermented foods, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Fisetin, a flavonoid from strawberries and apples, exerts senolytic activity by selectively eliminating senescent cells via PI3K/AKT and Bcl-2/Bcl-xL inhibition, with emerging clinical evidence. Berberine, an isoquinoline alkaloid from Berberis species, modulates metabolic dysfunction via AMP-activated protein kinase (AMPK) activation and reshapes gut microbiota composition through direct high intraluminal exposure, with the most extensive clinical dataset of the four compounds. Urolithin A, a gut microbiome-derived postbiotic from ellagitannins in pomegranates and nuts, induces mitophagy via PINK1/Parkin and has been evaluated in a growing number of registered human clinical trials. Together, the four compounds primarily target distinct but complementary aging-associated pathways (autophagy, senolysis, metabolic regulation, mitophagy), suggesting rational potential for combined functional food formulations. Limited direct evidence for their combined use and the need for dedicated co-administration studies are discussed, alongside bioavailability, safety, and regulatory considerations."

As geroscience increasingly prioritizes healthspan over lifespan, nutritional interventions targeting multiple aging mechanisms have gained attention as accessible strategies to mitigate age-related functional decline. This mini review synthesizes recent evidence on how the bioactivities of two food-derived geroprotective compounds, pyrroloquinoline quinone (PQQ) and spermidine (SPD), intersect with the hallmarks of aging and their distinct and overlapping roles in maintaining cellular homeostasis. PQQ primarily functions as a mitochondrial and redox regulator, enhancing mitochondrial biogenesis and bioenergetic capacity through the AMP-activated protein kinase (AMPK) and sirtuin1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator 1-alpha pathways. In contrast, SPD acts as a key regulator of cellular quality control by inducing macroautophagy and preserving proteostasis, largely through modulation of histone and autophagy-related protein acetylation. These complementary mechanisms converge on several key hallmarks of aging, including genomic instability, deregulated nutrient sensing, mitochondrial dysfunction, and chronic inflammation. The anti-aging mechanisms of PQQ and SPD originate from distinct upstream biochemical processes but converge on shared signaling hubs, including the AMPK/SIRT1 axis and autophagy-related networks. This convergence suggests a coordinated network-level complementarity that may offer a more robust intervention against age-related decline than targeting independent pathways alone."

Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration. Beyond its canonical role in macroautophagy, membrane atg8ylation also occurs on preexisting, non-autophagosomal single membranes through Conjugation of ATG8s to Single Membranes (CASM), positioning this pathway as a rapid response to membrane stress.

These ligases convert damage signals into spatially restricted membrane atg8ylation, generating a membrane-associated platform that coordinates multiple downstream pathways. These include ESCRT-dependent membrane repair, ER-lysosome lipid transfer, membrane tubulation, and stress granule formation. When repair fails, membrane atg8ylation regulates lysophagy and activates lysosomal biogenesis and regeneration to restore lysosomal homeostasis. These emerging findings define membrane atg8ylation as a central organizer of membrane quality control rather than a pathway merely confined to macroautophagy.

Although these disorders have different clinical features which affect cognition, movement and other vital body functions, they share key underlying molecular and cellular processes. This starts with protein misfolding and aggregation, mitochondrial dysfunction, oxidative stress, dysregulated protein homeostasis, neuroinflammation, and disrupted cell death pathways. Recent findings have added disease-specific processes, like amyloid-\u03b2 and tau aggregates in AD, \u03b1-synuclein aggregation and mitophagy failure in PD's, TDP-43-related impaired RNA metabolism in ALS, and mutant huntingtin causing transcription aberrations in HD. Protein interactome network analysis showed mechanistic crosstalk between pathogenic proteins of AD and PD. New evidence highlights how lysosomal dysfunction, endoplasmic reticulum stress, and microglial activation, act as a common axis in neurodegeneration. Advancements in genomics and epigenomics have found shared genetic risk loci and regulatory processes that affect how diseases develop and progress. Simultaneously, new biomarkers like circulating microRNAs, exosome-related pathological proteins, neurofilament light chain, inflammatory cytokines, and microglial activation markers are powering early diagnosis tools and disease variations. New imaging techniques also allow for the identification of protein aggregations before symptoms appear. Overall, these findings are accelerating targeted treatments and personalized medicine aimed at disease progression.

Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA."

Loss of C9orf72 and SMCR8 in mice causes age\u2011dependent neuroinflammation and microgliosis, with microglia adopting a disease-associated state. In aged brain and spinal cord tissue, microglia display lysosomal damage marked by galectin\u20113 accumulation.

Notably, mutant microglia accumulate GTP\u2011bound RAB8A, which becomes hyperphosphorylated and mislocalized to RAB7-positive, LAMP1-negative vesicles.

We reanalysed the Genetic and Epigenetic Signatures of Translational Ageing Laboratory Testing(GESTALT) paired RNA sequencing (RNA-seq) and tandem mass tag (TMT) proteome from 82 donors (aged 22-89) using Data Integration Analysis for Biomarker discovery using Latent cOmponents (DIABLO) for supervised multi-omics integration, weighted gene co-expression network analysis (WGCNA), external Genotype-Tissue Expression(GTEx) transcriptomic comparison, network medicine proximity mapping and CDOCKER molecular docking. Three analyses converged on the autophagy-lysosome axis: Kyoto Encyclopaedia of Genes and Genomes (KEGG) Lysosome ranked first in discordant-quadrant analysis; gene set enrichment analysis (GSEA) identified vacuole organisation and macroautophagy as the top age-upregulated Gene Ontology (GO) terms; and WGCNA recovered KEGG Lysosome in the brown module. Module regression localised most proteomic age signals to the lysosomal degradative-capacity module, whereas the proteasome was unaffected. McNemar testing and GTEx comparison supported a protein-side, post-transcriptional origin. TCIRG1, CTSA and ATP6V0D1 were recurrent hubs. Network proximity computationally prioritised hydroxytyrosol as a lysosomal-degradative-capacity-preferential candidate, and CDOCKER on cathepsin A linked its advantage over tyrosol to an ortho-hydroxyl group forming additional hydrogen bonds. These results support protein-layer-dominant autophagy-lysosome remodelling as a feature of dermal fibroblast ageing and suggest a cell-type-resolved computational route from ageing proteomics to testable dietary candidates."

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application."

Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice. Our findings reveal that placental AOC1-spermidine-EIF5A-autophagy axis is essential for parturition timing and offer a potential therapeutic strategy for preterm birth."

This review summarizes recent advances in understanding how HDL function is affected by its associated proteins, demonstrating that this is a more appropriate lens through which to assess HDL's protective capacity. Recent publications have demonstrated an inverse relationship between ApoM and clinical outcomes in chronic kidney disease and its concomitant cardiovascular indications. Mechanistic studies show that ApoM's regulation of mitochondrial function and autophagy are likely contributors to this effect. Additionally, ApoA-I, serum amyloid albumin (SAA), and SR-B1 have recently been highlighted as key regulators of atherogenesis through their ability to prevent LDL transcytosis and arterial entrapment by proteoglycans. Lastly, a novel mechanism is described wherein HDL-bound endotoxin is degraded through the endosome-lysosome pathway in an SR-B1-dependent manner, attenuating IL-1\u03b2 activation. In the same study, inhibition of CETP (cholesterol ester transfer protein) increased HDL and improved mortality in a mouse model of sepsis, highlighting this pathway's importance and therapeutic potential of CETP inhibition, which is currently in key clinical trials. HDL regulates inflammation and CVD through a variety of mechanisms independent of reverse cholesterol transport, including autophagy, LDL deposition, endotoxin clearance."

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

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.

Here, we report that the M337V mutation in TDP43 exacerbates its proteotoxicity relative to the wild-type protein. Concurrently, multi-omics analysis revealed a pronounced downregulation of TRIM16 in motor neuron-like cells expressing either wild-type or M337V mutant TDP43. Functional studies demonstrated that TRIM16 overexpression effectively mitigated oxidative stress, restored mitochondrial integrity, and suppressed ferroptosis. Mechanistically, TRIM16 promoted the ubiquitination and degradation of Keap1, thereby facilitating the activation of Nrf2-mediated antioxidant genes. Furthermore, we identified the iron import receptor TFR1 as a novel ubiquitination substrate of TRIM16.

Here, we show that psychological stress impairs HSC self-renewal and lymphoid differentiation, inducing aging-like phenotypes. Stress suppresses neuronal activity in the medial prefrontal cortex (mPFC) and periaqueductal gray (PAG), leading to HSC dysfunction, whereas chemogenetic activation of these regions restores HSC function. Psychological stress or chemogenetic inhibition of the mPFC and PAG reduces the abundance of L. reuteri in the gut microbiota and lowers spermidine levels. Mechanistically, spermidine depletion suppresses mitochondrial autophagy, promotes mitochondrial peroxidative stress, and increases ferroptotic stress in HSCs. We further demonstrate that mPFC and PAG activity regulate the intestinal environment through a sympathetic pathway, reducing intestinal mucin levels, L. reuteri abundance, and spermidine levels. These findings identify a brain-gut-bone marrow axis linking psychological stress to aging-like HSC dysfunction through sympathetic regulation of intestinal microbiota and spermidine metabolism."

Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations.

Although these disorders are often clinically defined by symptoms and affected brain regions, many are mechanistically linked to abnormal protein accumulation, misfolding, impaired proteostasis, RNA dysregulation, mitochondrial dysfunction, and neuroinflammation. In this Perspective article, I discuss major neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, dementia with Lewy bodies, multiple system atrophy, amyotrophic lateral sclerosis, frontotemporal dementia, Huntington's disease, prion diseases, spinocerebellar ataxias, and spinal muscular atrophy, through the lens of disease-associated proteins and experimental modeling. I argue that a protein-centered framework provides a useful approach for understanding disease mechanisms and selecting transgenic mouse models, while recognizing that aging, cellular context, neuroinflammation, mitochondrial dysfunction, vascular dysfunction, and other disease modifiers also shape neurodegeneration. Transgenic and genetically engineered mouse models have been essential for dissecting the pathogenic roles of amyloid-\u03b2, tau, \u03b1-synuclein, TDP-43, SOD1, FUS, C9ORF72-associated dipeptide repeat proteins, mutant huntingtin, prion protein, ataxins, and SMN deficiency. However, these models have important limitations, including artificial overexpression, familial mutation bias, species differences, and incomplete representation of aging-related sporadic diseases. Rather than seeking a single \"best\" model, a more productive strategy is to adopt model portfolios tailored to specific biological questions and to integrate mouse studies with human cellular models, postmortem tissue, omics approaches, and biomarker-based validation. Such an approach may improve mechanistic insight, strengthen translational relevance, and enhance the predictive value of preclinical neurodegenerative disease research."

Here, we defined the lncRNA landscape across iPSC-derived neurons, astrocytes, and microglia harboring the frontotemporal dementia-associated MAPT IVS10+16 mutation and investigated how lncRNA dysregulation interfaces with tau pathology. Transcriptomic analyses revealed extensive cell-type specific lncRNA expression changes, with neurons exhibiting the greatest degree of mutation-associated remodeling. Comparative analyses with MAPT IVS10+16 patient brain tissue identified NORAD and MIR22HG as lncRNAs significantly dysregulated across all three cell types and human brains. NORAD was also altered in Alzheimer's disease and Parkinson's disease brains, suggesting a broader role in neurodegenerative disease. Mechanistically, NORAD-associated protein networks converged on pathways related to RNA regulation, cytoskeletal organization, proteostasis, and tau interaction networks. Given the established role of NORAD in regulating PUM1 and PUM2 RNA-binding (pumilio) proteins, we examined the NORAD-pumilio axis and identified enrichment of pumilio-associated pathways linked to autophagy, endocytosis, proteostasis, and cytoskeletal regulation. NORAD depletion reduced tau seeding and uptake, whereas functional depletion of PUM1 or PUM2 increased both processes, supporting an antagonistic relationship between NORAD and pumilio signaling in modulation of tau aggregation. Together, these findings identify widespread lncRNA dysregulation across neural cell types in the setting of a MAPT mutation and nominate the NORAD-pumilio axis as a regulatory pathway linking RNA homeostasis and tau propagation biology."

The C9orf72 repeat expansion is bidirectionally transcribed into sense and anti-sense RNA foci, and also produces dipeptide repeats (DPRs) via a non-canonical translation mechanism known as repeat-associated (RAN) translation. Each of these components of the G4C2 repeat expansion cause neurodegenerative effects in animal models when expressed in neurons, but impacts from glial expression are more poorly understood. Here, we use glial cell type-specific expression of individual DPRs, of RNA repeat-only, or of the G4C2 repeat, that produces both DPRs and RNA repeats, to systematically investigate glial toxicity of each component. We find that as with neurons, the GR and G4C2 transgenes produce the highest degree of toxicity when expressed in glia. Each of these transgenes are capable to produce the GR DPR, which also is the most toxic factor in neurons. We demonstrate that both the GR and G4C2 transgenes cause activation of mdg4, an endogenous retrovirus (ERV). Such ERV expression is a hallmark of TDP-43 dysfunction that is commonly observed in C9orf72 patients. We find that glial expression of either the GR or the G4C2 transgene is toxic to glial cells, but such expression does not cause loss nearby neurons. However, blocking apoptotic signaling within glia that express either GR or G4C2 via expression of the p35 caspase inhibitor further exacerbates effects on lifespan and ablating such glia via expression of the proapoptotic reaper gene partially ameliorates these effects. Together, these results indicate that expression of toxic C9orf72 components in glia produces deleterious effects on lifespan, though potentially through different mechanisms than seen in TDP-43 models of ALS/FTD."

As geroscience increasingly prioritizes healthspan over lifespan, nutritional interventions targeting multiple aging mechanisms have gained attention as accessible strategies to mitigate age-related functional decline. This mini review synthesizes recent evidence on how the bioactivities of two food-derived geroprotective compounds, pyrroloquinoline quinone (PQQ) and spermidine (SPD), intersect with the hallmarks of aging and their distinct and overlapping roles in maintaining cellular homeostasis. PQQ primarily functions as a mitochondrial and redox regulator, enhancing mitochondrial biogenesis and bioenergetic capacity through the AMP-activated protein kinase (AMPK) and sirtuin1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator 1-alpha pathways. In contrast, SPD acts as a key regulator of cellular quality control by inducing macroautophagy and preserving proteostasis, largely through modulation of histone and autophagy-related protein acetylation. These complementary mechanisms converge on several key hallmarks of aging, including genomic instability, deregulated nutrient sensing, mitochondrial dysfunction, and chronic inflammation. The anti-aging mechanisms of PQQ and SPD originate from distinct upstream biochemical processes but converge on shared signaling hubs, including the AMPK/SIRT1 axis and autophagy-related networks. This convergence suggests a coordinated network-level complementarity that may offer a more robust intervention against age-related decline than targeting independent pathways alone."

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."

IL17A (interleukin 17A), a proinflammatory cytokine primarily secreted by Th17 and \u03b3\u03b4 T cells, has been implicated in immune-mediated neurodegeneration. However, the role of IL17A in the pathogenesis of HD remains poorly understood. Here, we identify IL17A as a critical pathogenic factor in HD that promotes neuroinflammation, mHTT aggregation, and autophagy-lysosomal dysfunction. IL17A disrupts autophagic flux by downregulating CTSB and CTSD, inducing SQSTM1/p62 and MAP1LC3B-II/LC3-II accumulation, and impairing lysosomal reformation. Mechanistically, IL17A suppresses lysosomal biogenesis by inhibiting the nuclear translocation of TFE3. This regulation occurs via a novel GSK3B/GSK-3\u03b2-TFE3 signaling pathway. Therapeutic neutralization of IL17A with a monoclonal antibody (IL17A mAb) ameliorates disease phenotypes in R6/2 HD mice, improving motor performance, extending survival, and reducing gliosis. IL17A mAb also attenuates mHTT aggregation and enhances neuroprotective signaling, as evidenced by increased expression of DLG4/PSD-95, phosphorylated CREB1, and BDNF. Moreover, IL17A mAb restores autophagy-lysosomal function by facilitating the clearance of protein aggregates and upregulating lysosomal enzymes and biogenesis markers, including CTSB, CTSD, PIP5K1A, and LAMP2. These findings establish IL17A as a key modulator of HD pathophysiology and highlight IL17A inhibition as a promising therapeutic strategy for targeting autophagy-lysosomal dysfunction in HD."

A structured narrative review of the literature was conducted using PubMed/MEDLINE up to March 2025. Relevant studies including clinical trials, observational studies, mechanistic research, and reviews were selected to summarise the molecular mechanisms and cardiovascular effects of HCQ. HCQ exerts multiple beneficial cardiovascular effects through anti-inflammatory, antithrombotic, metabolic, and endothelial-protective mechanisms. It reduces cytokine production, oxidative stress, platelet activation, and improves lipid and glucose profiles, contributing to decreased cardiovascular risk in patients with systemic autoimmune diseases. However, HCQ may also induce cardiotoxic effects, particularly with long-term use or high cumulative doses. These include QT interval prolongation, conduction abnormalities, and a rare but severe form of cardiomyopathy related to lysosomal dysfunction and impaired autophagy. The risk is higher in patients with advanced age, renal dysfunction, pre-existing heart disease, or concomitant use of QT-prolonging drugs. HCQ has a complex and context-dependent cardiovascular profile. While generally cardioprotective at standard doses, it may lead to rare but serious cardiac adverse effects in highrisk patients. A risk-adapted monitoring strategy is essential to optimise its benefit-risk balance in clinical practice."

While genetic studies have linked ANXA11 mutations (e.g., D40G) to disease, the precise molecular events converting aggregation into neurotoxicity and intercellular propagation remain elusive. We hypothesize that lysosomal integrity serves as a critical checkpoint in ANXA11 proteinopathy and that its failure drives disease progression. To model the human pathology of ANXA11, we generated pre-formed fibrils (PFFs) of wild-type and FTLD/ALS-linked D40G mutant ANXA11. Human iPSC-derived neurons, 3D cerebral organoids, and bulk RNA-sequencing were employed to investigate neurotoxicity. High-resolution imaging, lentiviral knockdown, and biochemical assays were performed to delineate the lysosomal damage response and the subsequent \"prion-like\" spreading of aggregates. The internalized ANXA11 fibrils accumulated in lysosomes, triggering lysosomal membrane permeabilization (LMP). The D40G mutation exacerbated this toxicity, leading to severe LMP, mitochondrial depolarization, and specific transcriptional downregulation of the dynactin subunit ACTR10. Mechanistically, we identified a protective signaling axis involving p38 MAPK, MK2, and HSP27 that senses ANXA11-induced lysosomal damage and initiates lysophagy. Notably, in human cerebral organoids, failure of this lysophagic clearance facilitated the cytoplasmic escape of ANXA11, thereby accelerating its seeding activity and propagation to neighboring cells. Pharmacological or genetic modulation of this pathway significantly altered neuronal survival. Our study established lysosomal rupture as a primary driver of ANXA11-associated neurodegeneration and validated the p38/MK2/HSP27 axis as a crucial defense mechanism in human neural tissue. These findings provide a novel mechanistic link between lysosomal quality control and ANXA11 propagation, highlighting that enhancing lysophagic flux represents a promising translational strategy to halt the progression of FTLD and ALS."

While amyloid-\u03b2 and tau have long been established as cardinal pathological hallmarks, growing evidence delineates TDP-43 as a critical participant of neurodegeneration, intricately interwoven with amyloid and tau pathologies. TDP-43 mislocalization, post-translational modifications, and aggregation potentiate neuronal loss through disruption of RNA metabolism, nucleocytoplasmic transport, and protein homeostasis. This tripartite interplay manifests in synergistic and possibly multidirectional pathological cascades that amplify neuronal vulnerability and cognitive decline, thereby complicating the clinical and pathological complexity of AD. Here, we critically reviewed the mechanistic crosstalk among TDP-43, amyloid-\u03b2, and tau, focusing on preclinical and clinical evidence, highlighting possible convergent pathways of aggregation, propagation, and neurodegeneration. Moreover, this review also evaluates mitochondrial dysfunction, autophagy failure, and inflammation as underlying events associated with TDP-43 pathology. Therefore, we argue for a reconceptualization of AD as a dynamic proteinopathy network, with TDP-43 as a core integrative node influencing disease onset and its progression. Notably, we discuss emerging diagnostic modalities associated with molecular tracers of TDP-43, providing prospects for future biomarker identification. Finally, this review articulates the translational relevance of TDP-43 therapy in AD and related neurological disorders, emphasizing the necessity of holistic approaches that transcend the traditional amyloid-tau paradigm to effectively tackle the full spectrum of AD pathobiology."

Chronic exposure to HGA promotes oxidative stress, chondroptosis, secondary amyloidosis, and impaired autophagy, an essential process for maintaining chondrocyte homeostasis. This study investigated the mechanisms potentially involved in autophagy dysregulation in AKU using the human C20/A4 chondrocyte line treated with 0.1 mM HGA, an established in vitro model of the disease. The findings were then verified using chondrocyte cells and cartilage tissue obtained from AKU biopsies. HGA treatment induced a time-dependent increase in oxidative stress, evidenced by elevated ROS levels, 4-HNE accumulation, and overproduction of mitochondrial superoxide. Autophagy assessment showed an early increase in autophagy-related markers, with increased LC3 and p62 expression and enhanced lysosomal biogenesis (LAMP1). However, prolonged HGA exposure was associated with reduced LC3/LAMP1 colocalization, persistent p62 accumulation, altered acidic compartment staining, and accumulation of autophagy-related structures, supporting a dysregulation of the autophagy-lysosomal pathway. Live-cell imaging further supported a transition from functional autophagy to lysosomal failure under chronic oxidative stress. Overall, this study suggests that prolonged HGA exposure disrupts the interplay between oxidative stress and autophagic flux. The progressive collapse of these adaptive mechanisms may contribute to chondrocyte degeneration and to the pathogenesis of cartilage damage in AKU."

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

Its acetyl group enables transport via monocarboxylate transporters, supporting blood-brain barrier penetration and efficient cellular uptake. Inside cells, levacetylleucine is metabolised by acylases, generating elevated levels of L-leucine that enhance mitochondrial bioenergetics and is thought to ameliorate lysosomal dysfunction indirectly. Here, we describe a direct effect of levacetylleucine on lysosomal regulation through modulation of TFEB, the master transcription factor for lysosomal and autophagy genes. Levacetylleucine rapidly alters TFEB translocation between the cytoplasm and the nucleus in a biphasic, homeostasis-restoring manner. In wild-type HeLa cells, levacetylleucine promotes TFEB activation and nuclear localisation. However, in NPC1 disease models, where we show that TFEB is over-activated and enriched in the nucleus due to lysosomal stress, levacetylleucine reduces nuclear TFEB and restores a more normal cytoplasmic-to-nuclear balance. These effects occur at clinically relevant concentrations associated with lysosomal storage reduction. The effects of the drug are stereospecific: while the L-enantiomer is active, the D-enantiomer and racemate show no effect, revealing the antagonistic properties of the D-enantiomer. This bidirectional normalisation of TFEB activity highlights a direct mechanism through which levacetylleucine modulates lysosomal and autophagic pathways in the HeLa cell model, giving mechanistic insight into its therapeutic potential in NPC, and also across diverse neurological and neurodevelopmental disorders."

Our data subsequently reveal a non-canonical action of PRKAR1A, a subunit of protein kinase A (PKA), in binding and activating FAM134B/C. At a molecular level, an amphipathic helix in the otherwise-disordered C terminus of FAM134B directly binds PRKAR1A dimers. Multimodal imaging reveals that this interaction occurs at interorganellar contact sites between the ER and liquid-like condensates of PRKAR1A. Mechanistically, ER-condensate contacts promote clustering of FAM134B/C with LC3B and recruit lysosomes, forming degradation hubs. Unexpectedly, these structures are found to control cytoplasmic signaling through FAM134B/C-mediated lysosomal sequestration of RhoA. Underscoring the physiologic relevance of this, these cytoplasmic-facing actions of FAM134B/C result in RhoA-dependent cell morphologic and migratory control in response to cyclic AMP (cAMP) stimuli.

Pathophysiological conditions in the cell cause the protein quality control system to depend on the autophagy-lysosome pathway (ALP) for degradation of accumulated misfolded proteins and mitochondrial turnover.

Our aim was to ameliorate disease processes resulting from mitochondrial abnormalities and misfolded protein aggregation by upregulating the ALP through overexpression of human BAG3 (hBAG3). The VCP-A232E mouse, a model for hIBM, received AAVrh74.tMCK.hBAG3 systemically at 3 months of age, and outcome measures, including functional, histological, and molecular studies, were assessed 9 months post-gene delivery. hBAG3 treatment improved treadmill running distance and rotarod duration, reduced the number of TDP-43-positive aggregates, and decreased the number of fibers showing abnormalities in mitochondrial enzyme histochemistry, compared with the untreated cohort. Moreover, hBAG3 gene therapy resulted in improvements in mitophagy and mitochondrial homeostasis observed as increased levels in mitophagy markers Parkin and Bnip3, mitochondria biogenesis marker Pgc1\u03b1 and mitochondrial DNA-encoded subunits of complex IV, Cox1 and Cox3. In addition, the LC-II/I ratio increased, indicating increased autophagic flux.

Genetic studies, including genome-wide association studies, have identified variants in BAG3, a key regulator of protein quality control (PQC), as contributors to both familial and sporadic forms of DCM. Impaired PQC and the accumulation of misfolded proteins (proteinopathy) have emerged as potential pathogenic mechanisms. Here, we investigated the molecular consequences of a recently identified BAG3 missense variant (V468\u202fM) associated with familial DCM. To assess the in vivo effects of the variant, human BAG3V468M was ectopically expressed in wild-type zebrafish embryos. Overexpression of BAG3V468M resulted in a DCM-like phenotype characterized by ventricular dilation, reduced heart rate, and impaired contractility. Transmission electron microscopy revealed marked disruption of myocardial ultrastructure and sarcomeric organization. To explore the impact on proteostasis, markers of autophagy (LC3-I/II and p62) were analyzed and showed no significant differences between BAG3V468M and control embryos under basal conditions. In contrast, analysis of the ubiquitin-proteasome system demonstrated a significant accumulation of ubiquitinated proteins in BAG3V468M-expressing embryos, suggesting impaired proteasomal protein clearance or increased proteotoxic stress. Expression of BAG3V468M induces a DCM-like phenotype in vivo associated with disrupted myocardial architecture and altered proteostasis. While canonical autophagy markers remain unchanged, the accumulation of ubiquitinated proteins points toward a disturbance in ubiquitin-mediated protein turnover. These findings implicate mutation-specific alterations in proteostasis as a potential mechanism contributing to BAG3-associated cardiomyopathy."

Limiting the damage caused by MIR is crucial but is still an unmet clinical need because of the complexity of the underlying mechanisms. Increasing evidence suggests that lysosomal autophagy plays a significant regulatory role in MIR injury. The specific mechanisms involved remain to be fully understood. We here systematically analyzed the murine MIR model database to screen the potentially protective lysosome-localized proteins against MIR injury. The positive hits were further functionally screened and validated for their capability on autophagy and hypoxia/reoxygenation insults of cardiomyocytes. After exploring the detailed molecular mechanism underlying the protective effects of the target protein, we generated target gene cardiac-specific knockout mice and overexpression mice to verify its function in mouse MIR injury models. LAPTM4A (lysosome-associated protein transmembrane 4 alpha) stood out as a significant protective lysosome-localized protein from the screening. LAPTM4A deficiency significantly heightened the inflammatory response and cell death both in primary cardiomyocytes and in a MIR-induced mouse model. Conversely, LAPTM4A overexpression exerted protective effects on cell viability and myocardial damage. Mechanistically, LAPTM4A interacts with Rubicon (Run domain Beclin1-interacting and cysteine-rich domain-containing protein), hindering its engagement within the Beclin1 complex, resulting in a robust augmentation of autophagic flux and thereby mitigating cardiac damage during reperfusion. It is important to note that Rubicon knockdown markedly reversed the aggravated injury induced by LAPTM4A knockdown, further verifying the effects of LAPTM4A depend on Rubicon. Our findings screened out and validated that LAPTM4A is a lysosome-localized protein exerting protective effects against MIR injury by facilitating autophagic flux. Targeting LAPTM4A represents a promising therapeutic strategy for mitigating MIR injury."

LysoDots display a viscosity-dependent fluorescence enhancement in glycerol-water systems while remaining insensitive to physiological pH and temperature variations. This turn-on response allows for the high-fidelity tracking of lysosomal microviscosity changes induced by exogenous stimuli, such as nystatin, and endogenous processes like rapamycin-induced autophagy. Confocal imaging demonstrates a remarkable colocalization of LysoDots with the commercial lysosome marker, LysoTracker Green (LTG), showing a Pearson's correlation coefficient of 0.92 in CAL-33 oral carcinoma cells, with the red emission effectively differentiating lysosomal viscosity profiles between cancerous and non-cancerous cells. Furthermore, the LysoDots were successfully employed in a neuronal model, SH-SY5Y cells, where the probe effectively tracked glutamate-induced lysosomal dysfunction, mimicking the pathology of lysosomal storage disorders, along with the viscosity restoration mediated by trehalose. These findings highlight the potential of LysoDots as a biocompatible, photostable, multi-functional nanomaterial for long-term monitoring of lysosomal dynamics and cellular homeostasis."

IL17A (interleukin 17A), a proinflammatory cytokine primarily secreted by Th17 and \u03b3\u03b4 T cells, has been implicated in immune-mediated neurodegeneration. However, the role of IL17A in the pathogenesis of HD remains poorly understood. Here, we identify IL17A as a critical pathogenic factor in HD that promotes neuroinflammation, mHTT aggregation, and autophagy-lysosomal dysfunction. IL17A disrupts autophagic flux by downregulating CTSB and CTSD, inducing SQSTM1/p62 and MAP1LC3B-II/LC3-II accumulation, and impairing lysosomal reformation. Mechanistically, IL17A suppresses lysosomal biogenesis by inhibiting the nuclear translocation of TFE3. This regulation occurs via a novel GSK3B/GSK-3\u03b2-TFE3 signaling pathway. Therapeutic neutralization of IL17A with a monoclonal antibody (IL17A mAb) ameliorates disease phenotypes in R6/2 HD mice, improving motor performance, extending survival, and reducing gliosis. IL17A mAb also attenuates mHTT aggregation and enhances neuroprotective signaling, as evidenced by increased expression of DLG4/PSD-95, phosphorylated CREB1, and BDNF. Moreover, IL17A mAb restores autophagy-lysosomal function by facilitating the clearance of protein aggregates and upregulating lysosomal enzymes and biogenesis markers, including CTSB, CTSD, PIP5K1A, and LAMP2. These findings establish IL17A as a key modulator of HD pathophysiology and highlight IL17A inhibition as a promising therapeutic strategy for targeting autophagy-lysosomal dysfunction in HD."

The 'protein-as-pathogen' model, where shed viral proteins act as soluble neurotoxins, is now central to understanding this phenomenon. This review presents the opinion that the most critical recent developments are not that these proteins are toxic, but how their mechanisms converge. We synthesize evidence from the last two years showing that proteins from diverse, highly infectious virus families with zoonotic potential (e.g. Coronaviridae, Flaviviridae, Orthomyxoviridae) engage shared host pathways. We focus on two convergent mechanisms: (1) the activation of glial Toll-like receptor (TLR)4/TLR2 signaling, which initiates a chronic neuroinflammatory cascade, and (2) the disruption of host proteostasis, which seeds neurodegenerative proteinopathies like alpha-synuclein and tau aggregation. This framework positions post-viral syndromes as mechanistically related disorders and identifies pan-viral therapeutic targets, such as TLR inhibitors and autophagy activators."

However, most studies in NMR cells have relied on static biochemical or ultrastructural readouts, leaving the dynamic organisation of autophagy in living cells poorly defined. Here, we establish a stable tandem fluorescent autophagy reporter in NMR skin fibroblasts using an mCherry-EGFP-LC3NMR construct to enable live-cell, single-cell resolution analysis of ALP dynamics. Under basal conditions, NMR skin fibroblasts exhibit a greater abundance of LC3-positive structures than HeLa cells, together with a mixed population of autophagosomes and autolysosomes, indicating a distinct steady-state organisation of the ALP. Chloroquine (CQ)-induced lysosomal stress caused the expected accumulation of LC3-positive structures but also triggered the formation of large cytoplasmic vacuoles in NMR skin fibroblasts. Importantly, this vacuolation was not associated with acute cytotoxicity and progressively resolved following CQ removal, accompanied by reorganisation of LC3-positive compartments and recovery of lysosomal acidity. Electron microscopy showed that CQ-induced vacuoles are membrane-bound, containing internal material and co-existing with multiple ALP-related vesicular compartments. Primary NMR skin fibroblasts display a similar vacuolation phenotype, indicating that this response is not an artefact of immortalisation or reporter expression. Together, these findings establish a live-cell platform for analysing autophagy in NMR cells and identify a distinctive, reversible vacuolation response to lysosomal stress, consistent with dynamic remodelling of the lysosomal system within NMR skin fibroblasts."

Pathophysiological conditions in the cell cause the protein quality control system to depend on the autophagy-lysosome pathway (ALP) for degradation of accumulated misfolded proteins and mitochondrial turnover. BCL2-associated athanogene 3 (BAG3) protein has a role in initiating the ALP. Our aim was to ameliorate disease processes resulting from mitochondrial abnormalities and misfolded protein aggregation by upregulating the ALP through overexpression of human BAG3 (hBAG3). The VCP-A232E mouse, a model for hIBM, received AAVrh74.tMCK.hBAG3 systemically at 3 months of age, and outcome measures, including functional, histological, and molecular studies, were assessed 9 months post-gene delivery. hBAG3 treatment improved treadmill running distance and rotarod duration, reduced the number of TDP-43-positive aggregates, and decreased the number of fibers showing abnormalities in mitochondrial enzyme histochemistry, compared with the untreated cohort. Moreover, hBAG3 gene therapy resulted in improvements in mitophagy and mitochondrial homeostasis observed as increased levels in mitophagy markers Parkin and Bnip3, mitochondria biogenesis marker Pgc1\u03b1 and mitochondrial DNA-encoded subunits of complex IV, Cox1 and Cox3. In addition, the LC-II/I ratio increased, indicating increased autophagic flux.

However, whether GCGR directly confers renoprotection and the underlying mechanisms remain unclear. Here, using tubule-specific GCGR loss- and gain-of-function mouse models and human kidney samples, we show that tubular GCGR signaling exerts an important renoprotective role in DKD. Tubular GCGR expression is reduced in humans and mice with DKD and correlates with worse kidney function and increased renal injury. Genetic ablation of tubular GCGR markedly exacerbates DKD and induces pronounced phospholipid accumulation within enlarged lysosomes. Mechanistically, GCGR loss disrupts its association with the V-ATPase V1A subunit ATP6V1A, compromises V1-V0 assembly, and thereby impairs lysosomal acidification. This defect leads to impaired phospholipid hydrolysis and protease maturation, blockade of autophagic flux, and ultimately tubular cell injury. In vivo, ATP6V1A overexpression markedly reverses GCGR deficiency-induced lysosomal dysfunction and DKD progression. Consistently, re-expression of tubular GCGR via AAV9 restores lysosomal function, reduces phospholipid accumulation, and mitigates renal injury in DKD. Together, these findings provide genetic evidence for the renoprotective role of tubular GCGR in DKD, delineate a kidney-intrinsic GCGR-ATP6V1A-lysosome axis that protects tubular integrity, and extend prior GCGR-in-kidney observations into a more concrete GCGR-lysosome mechanism."

Although lysosomal dysfunction is closely associated with cellular aging, the role of V-ATPase in regulating lysosomal function during photoaging remains incompletely understood. By screening a V-ATPase-targeted siRNA library and validating the results using publicly available single-cell transcriptomic datasets, we identified ATP6V1A as a key regulator of UVB-induced cellular senescence. Furthermore, ATP6V1A knockdown exacerbated the UVB-induced cellular senescence and impaired lysosomal acidification and membrane integrity, whereas ATP6V1A overexpression effectively alleviated keratinocyte senescence, lysosomal dysfunction and autophagy inhibition.

Progranulin haploinsufficiency, a leading genetic cause of familial FTD, disrupts lysosomal function, lipid metabolism, autophagy, and neuroimmune signaling across multiple cell types. Increasing evidence indicates that microglia are particularly sensitive to progranulin loss, exhibiting elevated complement activation that contributes to TDP-43 proteinopathy and neuronal dysfunction. Here, we investigate the biological role of restoring progranulin exclusively within microglia by transplanting human induced pluripotent stem cell-derived microglial progenitors into progranulin (Grn)-deficient mice. We find that engraftment of wild-type, but not Grn-deficient, human microglia restore brain-wide progranulin levels, normalize microglial transcriptional states, and ameliorate pathological, functional, and behavioral phenotypes associated with progranulin loss. Because human microglia are the only source of progranulin in this system, these findings demonstrate that microglial progranulin is sufficient to restore key aspects of cellular, circuit, and behavioral homeostasis in a progranulin-deficient FTD model. More broadly, this work highlights a central, microglia-intrinsic role for progranulin in maintaining brain function and provides a framework for dissecting microglia-specific mechanisms across FTD and related neurodegenerative disorders."

The mitochondrial dysfunction is one of the primary sources of glial activation and dopaminergic neuron loss in Parkinson's disease (PD). The key biochemical elements of the pathogenesis of PD include impaired oxidative phosphorylation, elevated generation of reactive oxygen species (ROS), and impaired mitophagy. This review is a synthesis and stringent evaluation of recent experimental, clinical and genetic studies relating mitochondrial dysfunction and Parkinson's disease (PD). We examined information on bioenergetics, mitochondrial dynamics, calcium homeostasis, and interactions between neurons and glia. The molecular and therapeutic importance of therapies, such as mitophagy modulators, bioenergetic enhancers, and mitochondrial antioxidants, was investigated. The absence of Complex I, excess ROS, mitochondrial DNA damage, and nonfunctioning fusionfission cycles leads to neurodegeneration. The glial metabolic abnormalities worsen the oxidative stress and neuroinflammation, weakening the support of the neurons. The effects of impaired mitophagy are the accumulation of dysfunctional mitochondria, and the effects of calcium overload disrupt energy metabolism. Neuroprotective effects of such substances as spermidine, urolithin A, resveratrol, \u03b1lipoic acid, MitoQ, SkQ1, or CoQ10 have been shown using preclinical research. Sacrifices such as exercising and proper dieting enable the mitochondria to perform better and become stronger. Mitochondrial dysfunction enhances the progression of PD through oxidative stress, bioenergetic breakdown, and inflammatory signalling. Attention to these related systems is an entire way to alter the direction of a disease. PD can be treated using an increase in mitochondrial quality control, redox regulation, and metabolic efficiency. Continued studies in the framework of precision medicine are required to validate the safety and effectiveness of mitochondrial-targeted medications."

Over the past decade, a rapidly expanding literature has identified galectins as regulators of microglial activation, misfolded protein pathology, vesicle damage sensing, autophagy, synaptic plasticity, myelination, vascular repair, and neuroimmune communication. Galectins operate across intracellular and extracellular compartments to integrate cellular stress and innate immune signaling. Here, we review CNS studies of galectin-1, galectin-3, galectin-4, galectin-8, and galectin-9, focusing primarily on work published from 2019 onward while incorporating selected earlier studies to establish foundational concepts. Across experimental models and human studies, galectins orchestrate microglial state transitions, regulate aggregation and propagation of amyloid-\u03b2, tau, \u03b1-synuclein, and mutant huntingtin, and function as intracellular sensors of vesicle and lysosomal damage. Multiple studies further establish galectins as biomarkers and therapeutic targets across Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, stroke, traumatic brain injury, spinal cord injury, retinal degeneration, and chronic pain. Importantly, this review highlights a stage- and context-dependent paradox in which the same galectin axis can amplify neuroinflammation and proteopathic spread in some settings yet support recovery or tissue protection in others. Together, these findings position galectins as central regulators that convert intracellular stress into coordinated neuroimmune programs shaping proteinopathy, circuit dysfunction, and tissue remodeling."

An emerging transcriptomic process that is also increasingly implicated in brain aging, neuroinflammation, and disease is the dysregulation of transposable elements (TEs), repetitive genomic sequences with the potential to cause cellular stress/dysfunction. However, there are limited data on microglial TE transcript patterns in these contexts. Here, we analyzed multiple RNA-seq datasets from isolated human and mouse microglia across aging, Alzheimer's disease (AD), and AD-associated pathology. In contrast to previous observations based on whole-brain tissue and other brain cell types, we found that microglial TE transcript levels remained relatively consistent throughout most of the human lifespan before increasing in late life. We also found that TE transcript levels in microglia from AD patients showed minimal changes compared to age-matched controls, and in RNA-seq analyses of transgenic AD mouse models we observed pathology-associated TE transcript decreases. Subsequent analyses identified inverse associations between TE transcript levels and autophagy/lysosome-related gene expression, and in\u00a0vitro studies suggested that aging- and AD-relevant stimuli, as well as pharmacological autophagy inhibition, modulate TE transcript expression in cultured human microglia. Together, these data provide novel insight into TE transcript dynamics in microglia, highlighting TE transcript patterns that differ from those observed in whole-brain samples and other cell types in aging and AD."

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n### [CLAIM EVALUATED AND ANSWER TO USER]\n\"Discovered Hypothesis: Spermidine-mediated autophagic activation may serve as an upstream regulator of lysosomal TMEM175 activity to prevent proteinopathy in C9orf72-ALS/FTD models.\"\n\nThe proposed hypothesis that spermidine-mediated autophagic activation functions as an upstream regulator of TMEM175 activity to prevent proteinopathy in C9orf72-ALS/FTD models is biologically plausible based on the convergence of identified cellular pathways; however, the provided literature lacks explicit experimental confirmation of a direct causal link between spermidine-induced autophagy and TMEM175 channel modulation. The dataset confirms that spermidine induces autophagy via EP300 inhibition and other mechanisms, and that TMEM175 dysregulation contributes to neurodegenerative pathogenesis, yet the two are not explicitly linked in the current corpus.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis of geroprotective polyamines and lysosomal ion channel regulation indicates that while both systems are critical for maintaining proteostasis, the specific regulatory axis connecting spermidine-driven autophagy to TMEM175-mediated lysosomal acidification in C9orf72-ALS/FTD pathology remains an unverified, albeit mechanistically sound, cross-talk intersection.\n\n### [INTRODUCTION & JUSTIFICATION]\nLysosomal dysfunction is recognized as a fundamental driver of neurodegenerative pathology. Spermidine, a dietary polyamine, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Autophagic pathways, including those maintained by the C9orf72/SMCR8 complex, are vital for microglial homeostasis and lysosomal repair. Simultaneously, TMEM175 serves as a lysosomal cation channel essential for maintaining lysosomal pH and function. Dysregulation of the autophagy-lysosomal pathway is a converging mechanism of pathology in C9orf72-associated diseases. While evidence indicates that pharmacological activation of autophagy can mitigate DPR accumulation and proteostatic stress in C9orf72 models, a direct regulatory relationship between spermidine and the TMEM175 channel remains a high-potential hypothesis for future investigation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   TMEM175 activity can be synergistically modulated, suggesting complex channel gating that might be responsive to metabolic states influenced by polyamines.\n*   The C9orf72/SMCR8 complex maintains microglial homeostasis via RAB8A-ESCRT-mediated lysosomal repair, providing a structural repair mechanism distinct from, yet likely coordinated with, macroautophagy.\n*   Lysosomal membrane damage acts as a specific trigger for ATG8-conjugation, indicating that membrane integrity and ionic flux are tightly coupled through the endo-lysosomal-lipid axis.\n*   The same galectin axis can amplify neuroinflammation and proteopathic spread in some settings yet support recovery or tissue protection in others, highlighting the context-dependency of lysosomal quality control.\n*   Protein-layer-dominant autophagy-lysosome remodelling is a feature of dermal fibroblast ageing, suggesting that post-transcriptional control of lysosomal capacity may precede transcriptional changes in systemic aging.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This narrative review examines four mechanistically distinct compounds, namely spermidine, fisetin, berberine, and urolithin A, as emerging functional food ingredients with scientifically supported effects on key hallmarks of human aging. Spermidine, a dietary polyamine from wheat germ and fermented foods, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Fisetin, a flavonoid from strawberries and apples, exerts senolytic activity by selectively eliminating senescent cells via PI3K/AKT and Bcl-2/Bcl-xL inhibition, with emerging clinical evidence. Berberine, an isoquinoline alkaloid from Berberis species, modulates metabolic dysfunction via AMP-activated protein kinase (AMPK) activation and reshapes gut microbiota composition through direct high intraluminal exposure, with the most extensive clinical dataset of the four compounds. Urolithin A, a gut microbiome-derived postbiotic from ellagitannins in pomegranates and nuts, induces mitophagy via PINK1/Parkin and has been evaluated in a growing number of registered human clinical trials. Together, the four compounds primarily target distinct but complementary aging-associated pathways (autophagy, senolysis, metabolic regulation, mitophagy), suggesting rational potential for combined functional food formulations. Limited direct evidence for their combined use and the need for dedicated co-administration studies are discussed, alongside bioavailability, safety, and regulatory considerations."

As geroscience increasingly prioritizes healthspan over lifespan, nutritional interventions targeting multiple aging mechanisms have gained attention as accessible strategies to mitigate age-related functional decline. This mini review synthesizes recent evidence on how the bioactivities of two food-derived geroprotective compounds, pyrroloquinoline quinone (PQQ) and spermidine (SPD), intersect with the hallmarks of aging and their distinct and overlapping roles in maintaining cellular homeostasis. PQQ primarily functions as a mitochondrial and redox regulator, enhancing mitochondrial biogenesis and bioenergetic capacity through the AMP-activated protein kinase (AMPK) and sirtuin1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator 1-alpha pathways. In contrast, SPD acts as a key regulator of cellular quality control by inducing macroautophagy and preserving proteostasis, largely through modulation of histone and autophagy-related protein acetylation. These complementary mechanisms converge on several key hallmarks of aging, including genomic instability, deregulated nutrient sensing, mitochondrial dysfunction, and chronic inflammation. The anti-aging mechanisms of PQQ and SPD originate from distinct upstream biochemical processes but converge on shared signaling hubs, including the AMPK/SIRT1 axis and autophagy-related networks. This convergence suggests a coordinated network-level complementarity that may offer a more robust intervention against age-related decline than targeting independent pathways alone."

Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration. Beyond its canonical role in macroautophagy, membrane atg8ylation also occurs on preexisting, non-autophagosomal single membranes through Conjugation of ATG8s to Single Membranes (CASM), positioning this pathway as a rapid response to membrane stress. Two E3-like ligase complexes, ATG16L1-ATG5-ATG12 and TECPR1-ATG5-ATG12, act as complementary sensors of lysosomal injury by detecting distinct physicochemical cues, including proton gradient collapse and lipid scrambling. These ligases convert damage signals into spatially restricted membrane atg8ylation, generating a membrane-associated platform that coordinates multiple downstream pathways. These include ESCRT-dependent membrane repair, ER-lysosome lipid transfer, membrane tubulation, and stress granule formation. When repair fails, membrane atg8ylation regulates lysophagy and activates lysosomal biogenesis and regeneration to restore lysosomal homeostasis. These emerging findings define membrane atg8ylation as a central organizer of membrane quality control rather than a pathway merely confined to macroautophagy. In this review, we summarize the current understanding of how membrane atg8ylation detects lysosomal damage and how this pathway coordinates other lysosomal quality control mechanisms to maintain lysosomal integrity."

Although these disorders have different clinical features which affect cognition, movement and other vital body functions, they share key underlying molecular and cellular processes. This starts with protein misfolding and aggregation, mitochondrial dysfunction, oxidative stress, dysregulated protein homeostasis, neuroinflammation, and disrupted cell death pathways. Recent findings have added disease-specific processes, like amyloid-\u03b2 and tau aggregates in AD, \u03b1-synuclein aggregation and mitophagy failure in PD's, TDP-43-related impaired RNA metabolism in ALS, and mutant huntingtin causing transcription aberrations in HD. Protein interactome network analysis showed mechanistic crosstalk between pathogenic proteins of AD and PD. New evidence highlights how lysosomal dysfunction, endoplasmic reticulum stress, and microglial activation, act as a common axis in neurodegeneration. Advancements in genomics and epigenomics have found shared genetic risk loci and regulatory processes that affect how diseases develop and progress. Simultaneously, new biomarkers like circulating microRNAs, exosome-related pathological proteins, neurofilament light chain, inflammatory cytokines, and microglial activation markers are powering early diagnosis tools and disease variations. New imaging techniques also allow for the identification of protein aggregations before symptoms appear. Overall, these findings are accelerating targeted treatments and personalized medicine aimed at disease progression. This review highlights current insights into the molecular mechanisms of NDs and discusses new biomarkers and treatment targets that help future diagnostic and treatment strategies."

Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA."

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.

Haploinsufficiency of C9orf72, the most frequently mutated gene in\u00a0amyotrophic lateral sclerosis and frontotemporal dementia, has been linked to autophagy-lysosomal pathway defects, but the role\u00a0of C9orf72 in microglia remains unclear. Here, we identify the C9orf72/SMCR8 complex as a key regulator of microglial homeostasis through promoting lysosomal membrane repair. Loss of C9orf72 and SMCR8 in mice causes age\u2011dependent neuroinflammation and microgliosis, with microglia adopting a disease-associated state. In aged brain and spinal cord tissue, microglia display lysosomal damage marked by galectin\u20113 accumulation. Using a lysosomotropic agent to induce lysosomal damage in microglia, we find that C9orf72/SMCR8-deficient cells accumulate damaged lysosomes and show defective recruitment of phosphorylated RAB8A and the Endosomal Sorting Complexes Required for Transport (ESCRT) machinery\u00a0to damaged lysosomes. Notably, mutant microglia accumulate GTP\u2011bound RAB8A, which becomes hyperphosphorylated and mislocalized to RAB7-positive, LAMP1-negative vesicles. The GTPase-activating activity of the C9orf72/SMCR8 complex is essential for lysosomal repair.

We reanalysed the Genetic and Epigenetic Signatures of Translational Ageing Laboratory Testing(GESTALT) paired RNA sequencing (RNA-seq) and tandem mass tag (TMT) proteome from 82 donors (aged 22-89) using Data Integration Analysis for Biomarker discovery using Latent cOmponents (DIABLO) for supervised multi-omics integration, weighted gene co-expression network analysis (WGCNA), external Genotype-Tissue Expression(GTEx) transcriptomic comparison, network medicine proximity mapping and CDOCKER molecular docking. Three analyses converged on the autophagy-lysosome axis: Kyoto Encyclopaedia of Genes and Genomes (KEGG) Lysosome ranked first in discordant-quadrant analysis; gene set enrichment analysis (GSEA) identified vacuole organisation and macroautophagy as the top age-upregulated Gene Ontology (GO) terms; and WGCNA recovered KEGG Lysosome in the brown module.

Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice.

Recent publications have demonstrated an inverse relationship between ApoM and clinical outcomes in chronic kidney disease and its concomitant cardiovascular indications. Mechanistic studies show that ApoM's regulation of mitochondrial function and autophagy are likely contributors to this effect. Additionally, ApoA-I, serum amyloid albumin (SAA), and SR-B1 have recently been highlighted as key regulators of atherogenesis through their ability to prevent LDL transcytosis and arterial entrapment by proteoglycans.

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

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.

Here, we report that the M337V mutation in TDP43 exacerbates its proteotoxicity relative to the wild-type protein. Concurrently, multi-omics analysis revealed a pronounced downregulation of TRIM16 in motor neuron-like cells expressing either wild-type or M337V mutant TDP43. Functional studies demonstrated that TRIM16 overexpression effectively mitigated oxidative stress, restored mitochondrial integrity, and suppressed ferroptosis. Mechanistically, TRIM16 promoted the ubiquitination and degradation of Keap1, thereby facilitating the activation of Nrf2-mediated antioxidant genes. Furthermore, we identified the iron import receptor TFR1 as a novel ubiquitination substrate of TRIM16.

Stress suppresses neuronal activity in the medial prefrontal cortex (mPFC) and periaqueductal gray (PAG), leading to HSC dysfunction, whereas chemogenetic activation of these regions restores HSC function. Psychological stress or chemogenetic inhibition of the mPFC and PAG reduces the abundance of L. reuteri in the gut microbiota and lowers spermidine levels. Mechanistically, spermidine depletion suppresses mitochondrial autophagy, promotes mitochondrial peroxidative stress, and increases ferroptotic stress in HSCs. We further demonstrate that mPFC and PAG activity regulate the intestinal environment through a sympathetic pathway, reducing intestinal mucin levels, L. reuteri abundance, and spermidine levels.

Here, we investigated the effects of spermidine on lifespan, behavioral responses, brain tissue, target gene expression, and antioxidant status in Drosophila melanogaster model of age-dependent neurodegeneration. Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood. Lifespan analysis revealed that high-dose spermidine (5\u2009mM) reduced survival in both wild-type and sws1 mutants, whereas lower doses (0.5 and 1\u2009mM) significantly improved survival in mutants without affecting wild-type flies. Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM.

Although these disorders are often clinically defined by symptoms and affected brain regions, many are mechanistically linked to abnormal protein accumulation, misfolding, impaired proteostasis, RNA dysregulation, mitochondrial dysfunction, and neuroinflammation. In this Perspective article, I discuss major neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, dementia with Lewy bodies, multiple system atrophy, amyotrophic lateral sclerosis, frontotemporal dementia, Huntington's disease, prion diseases, spinocerebellar ataxias, and spinal muscular atrophy, through the lens of disease-associated proteins and experimental modeling. I argue that a protein-centered framework provides a useful approach for understanding disease mechanisms and selecting transgenic mouse models, while recognizing that aging, cellular context, neuroinflammation, mitochondrial dysfunction, vascular dysfunction, and other disease modifiers also shape neurodegeneration. Transgenic and genetically engineered mouse models have been essential for dissecting the pathogenic roles of amyloid-\u03b2, tau, \u03b1-synuclein, TDP-43, SOD1, FUS, C9ORF72-associated dipeptide repeat proteins, mutant huntingtin, prion protein, ataxins, and SMN deficiency. However, these models have important limitations, including artificial overexpression, familial mutation bias, species differences, and incomplete representation of aging-related sporadic diseases. Rather than seeking a single \"best\" model, a more productive strategy is to adopt model portfolios tailored to specific biological questions and to integrate mouse studies with human cellular models, postmortem tissue, omics approaches, and biomarker-based validation. Such an approach may improve mechanistic insight, strengthen translational relevance, and enhance the predictive value of preclinical neurodegenerative disease research."

Here, we defined the lncRNA landscape across iPSC-derived neurons, astrocytes, and microglia harboring the frontotemporal dementia-associated MAPT IVS10+16 mutation and investigated how lncRNA dysregulation interfaces with tau pathology. Transcriptomic analyses revealed extensive cell-type specific lncRNA expression changes, with neurons exhibiting the greatest degree of mutation-associated remodeling. Comparative analyses with MAPT IVS10+16 patient brain tissue identified NORAD and MIR22HG as lncRNAs significantly dysregulated across all three cell types and human brains. NORAD was also altered in Alzheimer's disease and Parkinson's disease brains, suggesting a broader role in neurodegenerative disease. Mechanistically, NORAD-associated protein networks converged on pathways related to RNA regulation, cytoskeletal organization, proteostasis, and tau interaction networks. Given the established role of NORAD in regulating PUM1 and PUM2 RNA-binding (pumilio) proteins, we examined the NORAD-pumilio axis and identified enrichment of pumilio-associated pathways linked to autophagy, endocytosis, proteostasis, and cytoskeletal regulation. NORAD depletion reduced tau seeding and uptake, whereas functional depletion of PUM1 or PUM2 increased both processes, supporting an antagonistic relationship between NORAD and pumilio signaling in modulation of tau aggregation. Together, these findings identify widespread lncRNA dysregulation across neural cell types in the setting of a MAPT mutation and nominate the NORAD-pumilio axis as a regulatory pathway linking RNA homeostasis and tau propagation biology."

The C9orf72 repeat expansion is bidirectionally transcribed into sense and anti-sense RNA foci, and also produces dipeptide repeats (DPRs) via a non-canonical translation mechanism known as repeat-associated (RAN) translation. Each of these components of the G4C2 repeat expansion cause neurodegenerative effects in animal models when expressed in neurons, but impacts from glial expression are more poorly understood. Here, we use glial cell type-specific expression of individual DPRs, of RNA repeat-only, or of the G4C2 repeat, that produces both DPRs and RNA repeats, to systematically investigate glial toxicity of each component. We find that as with neurons, the GR and G4C2 transgenes produce the highest degree of toxicity when expressed in glia. Each of these transgenes are capable to produce the GR DPR, which also is the most toxic factor in neurons. We demonstrate that both the GR and G4C2 transgenes cause activation of mdg4, an endogenous retrovirus (ERV). Such ERV expression is a hallmark of TDP-43 dysfunction that is commonly observed in C9orf72 patients. We find that glial expression of either the GR or the G4C2 transgene is toxic to glial cells, but such expression does not cause loss nearby neurons. However, blocking apoptotic signaling within glia that express either GR or G4C2 via expression of the p35 caspase inhibitor further exacerbates effects on lifespan and ablating such glia via expression of the proapoptotic reaper gene partially ameliorates these effects. Together, these results indicate that expression of toxic C9orf72 components in glia produces deleterious effects on lifespan, though potentially through different mechanisms than seen in TDP-43 models of ALS/FTD."

As geroscience increasingly prioritizes healthspan over lifespan, nutritional interventions targeting multiple aging mechanisms have gained attention as accessible strategies to mitigate age-related functional decline. This mini review synthesizes recent evidence on how the bioactivities of two food-derived geroprotective compounds, pyrroloquinoline quinone (PQQ) and spermidine (SPD), intersect with the hallmarks of aging and their distinct and overlapping roles in maintaining cellular homeostasis. PQQ primarily functions as a mitochondrial and redox regulator, enhancing mitochondrial biogenesis and bioenergetic capacity through the AMP-activated protein kinase (AMPK) and sirtuin1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator 1-alpha pathways. In contrast, SPD acts as a key regulator of cellular quality control by inducing macroautophagy and preserving proteostasis, largely through modulation of histone and autophagy-related protein acetylation. These complementary mechanisms converge on several key hallmarks of aging, including genomic instability, deregulated nutrient sensing, mitochondrial dysfunction, and chronic inflammation. The anti-aging mechanisms of PQQ and SPD originate from distinct upstream biochemical processes but converge on shared signaling hubs, including the AMPK/SIRT1 axis and autophagy-related networks. This convergence suggests a coordinated network-level complementarity that may offer a more robust intervention against age-related decline than targeting independent pathways alone."

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."

IL17A (interleukin 17A), a proinflammatory cytokine primarily secreted by Th17 and \u03b3\u03b4 T cells, has been implicated in immune-mediated neurodegeneration. However, the role of IL17A in the pathogenesis of HD remains poorly understood. Here, we identify IL17A as a critical pathogenic factor in HD that promotes neuroinflammation, mHTT aggregation, and autophagy-lysosomal dysfunction. IL17A disrupts autophagic flux by downregulating CTSB and CTSD, inducing SQSTM1/p62 and MAP1LC3B-II/LC3-II accumulation, and impairing lysosomal reformation. Mechanistically, IL17A suppresses lysosomal biogenesis by inhibiting the nuclear translocation of TFE3. This regulation occurs via a novel GSK3B/GSK-3\u03b2-TFE3 signaling pathway. Therapeutic neutralization of IL17A with a monoclonal antibody (IL17A mAb) ameliorates disease phenotypes in R6/2 HD mice, improving motor performance, extending survival, and reducing gliosis. IL17A mAb also attenuates mHTT aggregation and enhances neuroprotective signaling, as evidenced by increased expression of DLG4/PSD-95, phosphorylated CREB1, and BDNF. Moreover, IL17A mAb restores autophagy-lysosomal function by facilitating the clearance of protein aggregates and upregulating lysosomal enzymes and biogenesis markers, including CTSB, CTSD, PIP5K1A, and LAMP2. These findings establish IL17A as a key modulator of HD pathophysiology and highlight IL17A inhibition as a promising therapeutic strategy for targeting autophagy-lysosomal dysfunction in HD."

A structured narrative review of the literature was conducted using PubMed/MEDLINE up to March 2025. Relevant studies including clinical trials, observational studies, mechanistic research, and reviews were selected to summarise the molecular mechanisms and cardiovascular effects of HCQ. HCQ exerts multiple beneficial cardiovascular effects through anti-inflammatory, antithrombotic, metabolic, and endothelial-protective mechanisms. It reduces cytokine production, oxidative stress, platelet activation, and improves lipid and glucose profiles, contributing to decreased cardiovascular risk in patients with systemic autoimmune diseases. However, HCQ may also induce cardiotoxic effects, particularly with long-term use or high cumulative doses. These include QT interval prolongation, conduction abnormalities, and a rare but severe form of cardiomyopathy related to lysosomal dysfunction and impaired autophagy. The risk is higher in patients with advanced age, renal dysfunction, pre-existing heart disease, or concomitant use of QT-prolonging drugs. HCQ has a complex and context-dependent cardiovascular profile. While generally cardioprotective at standard doses, it may lead to rare but serious cardiac adverse effects in highrisk patients. A risk-adapted monitoring strategy is essential to optimise its benefit-risk balance in clinical practice."

While genetic studies have linked ANXA11 mutations (e.g., D40G) to disease, the precise molecular events converting aggregation into neurotoxicity and intercellular propagation remain elusive. We hypothesize that lysosomal integrity serves as a critical checkpoint in ANXA11 proteinopathy and that its failure drives disease progression. To model the human pathology of ANXA11, we generated pre-formed fibrils (PFFs) of wild-type and FTLD/ALS-linked D40G mutant ANXA11. Human iPSC-derived neurons, 3D cerebral organoids, and bulk RNA-sequencing were employed to investigate neurotoxicity. High-resolution imaging, lentiviral knockdown, and biochemical assays were performed to delineate the lysosomal damage response and the subsequent \"prion-like\" spreading of aggregates. The internalized ANXA11 fibrils accumulated in lysosomes, triggering lysosomal membrane permeabilization (LMP). The D40G mutation exacerbated this toxicity, leading to severe LMP, mitochondrial depolarization, and specific transcriptional downregulation of the dynactin subunit ACTR10. Mechanistically, we identified a protective signaling axis involving p38 MAPK, MK2, and HSP27 that senses ANXA11-induced lysosomal damage and initiates lysophagy. Notably, in human cerebral organoids, failure of this lysophagic clearance facilitated the cytoplasmic escape of ANXA11, thereby accelerating its seeding activity and propagation to neighboring cells. Pharmacological or genetic modulation of this pathway significantly altered neuronal survival. Our study established lysosomal rupture as a primary driver of ANXA11-associated neurodegeneration and validated the p38/MK2/HSP27 axis as a crucial defense mechanism in human neural tissue. These findings provide a novel mechanistic link between lysosomal quality control and ANXA11 propagation, highlighting that enhancing lysophagic flux represents a promising translational strategy to halt the progression of FTLD and ALS."

While amyloid-\u03b2 and tau have long been established as cardinal pathological hallmarks, growing evidence delineates TDP-43 as a critical participant of neurodegeneration, intricately interwoven with amyloid and tau pathologies. TDP-43 mislocalization, post-translational modifications, and aggregation potentiate neuronal loss through disruption of RNA metabolism, nucleocytoplasmic transport, and protein homeostasis. This tripartite interplay manifests in synergistic and possibly multidirectional pathological cascades that amplify neuronal vulnerability and cognitive decline, thereby complicating the clinical and pathological complexity of AD. Here, we critically reviewed the mechanistic crosstalk among TDP-43, amyloid-\u03b2, and tau, focusing on preclinical and clinical evidence, highlighting possible convergent pathways of aggregation, propagation, and neurodegeneration. Moreover, this review also evaluates mitochondrial dysfunction, autophagy failure, and inflammation as underlying events associated with TDP-43 pathology. Therefore, we argue for a reconceptualization of AD as a dynamic proteinopathy network, with TDP-43 as a core integrative node influencing disease onset and its progression. Notably, we discuss emerging diagnostic modalities associated with molecular tracers of TDP-43, providing prospects for future biomarker identification. Finally, this review articulates the translational relevance of TDP-43 therapy in AD and related neurological disorders, emphasizing the necessity of holistic approaches that transcend the traditional amyloid-tau paradigm to effectively tackle the full spectrum of AD pathobiology."

Chronic exposure to HGA promotes oxidative stress, chondroptosis, secondary amyloidosis, and impaired autophagy, an essential process for maintaining chondrocyte homeostasis. This study investigated the mechanisms potentially involved in autophagy dysregulation in AKU using the human C20/A4 chondrocyte line treated with 0.1 mM HGA, an established in vitro model of the disease. The findings were then verified using chondrocyte cells and cartilage tissue obtained from AKU biopsies. HGA treatment induced a time-dependent increase in oxidative stress, evidenced by elevated ROS levels, 4-HNE accumulation, and overproduction of mitochondrial superoxide. Autophagy assessment showed an early increase in autophagy-related markers, with increased LC3 and p62 expression and enhanced lysosomal biogenesis (LAMP1). However, prolonged HGA exposure was associated with reduced LC3/LAMP1 colocalization, persistent p62 accumulation, altered acidic compartment staining, and accumulation of autophagy-related structures, supporting a dysregulation of the autophagy-lysosomal pathway. Live-cell imaging further supported a transition from functional autophagy to lysosomal failure under chronic oxidative stress. Overall, this study suggests that prolonged HGA exposure disrupts the interplay between oxidative stress and autophagic flux. The progressive collapse of these adaptive mechanisms may contribute to chondrocyte degeneration and to the pathogenesis of cartilage damage in AKU."

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

Its acetyl group enables transport via monocarboxylate transporters, supporting blood-brain barrier penetration and efficient cellular uptake. Inside cells, levacetylleucine is metabolised by acylases, generating elevated levels of L-leucine that enhance mitochondrial bioenergetics and is thought to ameliorate lysosomal dysfunction indirectly. Here, we describe a direct effect of levacetylleucine on lysosomal regulation through modulation of TFEB, the master transcription factor for lysosomal and autophagy genes. Levacetylleucine rapidly alters TFEB translocation between the cytoplasm and the nucleus in a biphasic, homeostasis-restoring manner. In wild-type HeLa cells, levacetylleucine promotes TFEB activation and nuclear localisation. However, in NPC1 disease models, where we show that TFEB is over-activated and enriched in the nucleus due to lysosomal stress, levacetylleucine reduces nuclear TFEB and restores a more normal cytoplasmic-to-nuclear balance. These effects occur at clinically relevant concentrations associated with lysosomal storage reduction. The effects of the drug are stereospecific: while the L-enantiomer is active, the D-enantiomer and racemate show no effect, revealing the antagonistic properties of the D-enantiomer. This bidirectional normalisation of TFEB activity highlights a direct mechanism through which levacetylleucine modulates lysosomal and autophagic pathways in the HeLa cell model, giving mechanistic insight into its therapeutic potential in NPC, and also across diverse neurological and neurodevelopmental disorders."

To gain insight into these, we screen for cytoplasmic interactors of well-known receptors in mouse pancreatic ductal adenocarcinoma cells. Our data subsequently reveal a non-canonical action of PRKAR1A, a subunit of protein kinase A (PKA), in binding and activating FAM134B/C. At a molecular level, an amphipathic helix in the otherwise-disordered C terminus of FAM134B directly binds PRKAR1A dimers. Multimodal imaging reveals that this interaction occurs at interorganellar contact sites between the ER and liquid-like condensates of PRKAR1A. Mechanistically, ER-condensate contacts promote clustering of FAM134B/C with LC3B and recruit lysosomes, forming degradation hubs. Unexpectedly, these structures are found to control cytoplasmic signaling through FAM134B/C-mediated lysosomal sequestration of RhoA. Underscoring the physiologic relevance of this, these cytoplasmic-facing actions of FAM134B/C result in RhoA-dependent cell morphologic and migratory control in response to cyclic AMP (cAMP) stimuli.

Pathophysiological conditions in the cell cause the protein quality control system to depend on the autophagy-lysosome pathway (ALP) for degradation of accumulated misfolded proteins and mitochondrial turnover. BCL2-associated athanogene 3 (BAG3) protein has a role in initiating the ALP. Our aim was to ameliorate disease processes resulting from mitochondrial abnormalities and misfolded protein aggregation by upregulating the ALP through overexpression of human BAG3 (hBAG3). The VCP-A232E mouse, a model for hIBM, received AAVrh74.tMCK.hBAG3 systemically at 3 months of age, and outcome measures, including functional, histological, and molecular studies, were assessed 9 months post-gene delivery. hBAG3 treatment improved treadmill running distance and rotarod duration, reduced the number of TDP-43-positive aggregates, and decreased the number of fibers showing abnormalities in mitochondrial enzyme histochemistry, compared with the untreated cohort. Moreover, hBAG3 gene therapy resulted in improvements in mitophagy and mitochondrial homeostasis observed as increased levels in mitophagy markers Parkin and Bnip3, mitochondria biogenesis marker Pgc1\u03b1 and mitochondrial DNA-encoded subunits of complex IV, Cox1 and Cox3.

Genetic studies, including genome-wide association studies, have identified variants in BAG3, a key regulator of protein quality control (PQC), as contributors to both familial and sporadic forms of DCM. Impaired PQC and the accumulation of misfolded proteins (proteinopathy) have emerged as potential pathogenic mechanisms. Here, we investigated the molecular consequences of a recently identified BAG3 missense variant (V468\u202fM) associated with familial DCM. To assess the in vivo effects of the variant, human BAG3V468M was ectopically expressed in wild-type zebrafish embryos. Overexpression of BAG3V468M resulted in a DCM-like phenotype characterized by ventricular dilation, reduced heart rate, and impaired contractility. Transmission electron microscopy revealed marked disruption of myocardial ultrastructure and sarcomeric organization. To explore the impact on proteostasis, markers of autophagy (LC3-I/II and p62) were analyzed and showed no significant differences between BAG3V468M and control embryos under basal conditions. In contrast, analysis of the ubiquitin-proteasome system demonstrated a significant accumulation of ubiquitinated proteins in BAG3V468M-expressing embryos, suggesting impaired proteasomal protein clearance or increased proteotoxic stress. Expression of BAG3V468M induces a DCM-like phenotype in vivo associated with disrupted myocardial architecture and altered proteostasis. While canonical autophagy markers remain unchanged, the accumulation of ubiquitinated proteins points toward a disturbance in ubiquitin-mediated protein turnover. These findings implicate mutation-specific alterations in proteostasis as a potential mechanism contributing to BAG3-associated cardiomyopathy."

Limiting the damage caused by MIR is crucial but is still an unmet clinical need because of the complexity of the underlying mechanisms. Increasing evidence suggests that lysosomal autophagy plays a significant regulatory role in MIR injury. The specific mechanisms involved remain to be fully understood. We here systematically analyzed the murine MIR model database to screen the potentially protective lysosome-localized proteins against MIR injury. The positive hits were further functionally screened and validated for their capability on autophagy and hypoxia/reoxygenation insults of cardiomyocytes. After exploring the detailed molecular mechanism underlying the protective effects of the target protein, we generated target gene cardiac-specific knockout mice and overexpression mice to verify its function in mouse MIR injury models. LAPTM4A (lysosome-associated protein transmembrane 4 alpha) stood out as a significant protective lysosome-localized protein from the screening. LAPTM4A deficiency significantly heightened the inflammatory response and cell death both in primary cardiomyocytes and in a MIR-induced mouse model. Conversely, LAPTM4A overexpression exerted protective effects on cell viability and myocardial damage. Mechanistically, LAPTM4A interacts with Rubicon (Run domain Beclin1-interacting and cysteine-rich domain-containing protein), hindering its engagement within the Beclin1 complex, resulting in a robust augmentation of autophagic flux and thereby mitigating cardiac damage during reperfusion. It is important to note that Rubicon knockdown markedly reversed the aggravated injury induced by LAPTM4A knockdown, further verifying the effects of LAPTM4A depend on Rubicon. Our findings screened out and validated that LAPTM4A is a lysosome-localized protein exerting protective effects against MIR injury by facilitating autophagic flux. Targeting LAPTM4A represents a promising therapeutic strategy for mitigating MIR injury."

IL17A (interleukin 17A), a proinflammatory cytokine primarily secreted by Th17 and \u03b3\u03b4 T cells, has been implicated in immune-mediated neurodegeneration. However, the role of IL17A in the pathogenesis of HD remains poorly understood. Here, we identify IL17A as a critical pathogenic factor in HD that promotes neuroinflammation, mHTT aggregation, and autophagy-lysosomal dysfunction. IL17A disrupts autophagic flux by downregulating CTSB and CTSD, inducing SQSTM1/p62 and MAP1LC3B-II/LC3-II accumulation, and impairing lysosomal reformation. Mechanistically, IL17A suppresses lysosomal biogenesis by inhibiting the nuclear translocation of TFE3. This regulation occurs via a novel GSK3B/GSK-3\u03b2-TFE3 signaling pathway. Therapeutic neutralization of IL17A with a monoclonal antibody (IL17A mAb) ameliorates disease phenotypes in R6/2 HD mice, improving motor performance, extending survival, and reducing gliosis. IL17A mAb also attenuates mHTT aggregation and enhances neuroprotective signaling, as evidenced by increased expression of DLG4/PSD-95, phosphorylated CREB1, and BDNF. Moreover, IL17A mAb restores autophagy-lysosomal function by facilitating the clearance of protein aggregates and upregulating lysosomal enzymes and biogenesis markers, including CTSB, CTSD, PIP5K1A, and LAMP2. These findings establish IL17A as a key modulator of HD pathophysiology and highlight IL17A inhibition as a promising therapeutic strategy for targeting autophagy-lysosomal dysfunction in HD."

The 'protein-as-pathogen' model, where shed viral proteins act as soluble neurotoxins, is now central to understanding this phenomenon. This review presents the opinion that the most critical recent developments are not that these proteins are toxic, but how their mechanisms converge. We synthesize evidence from the last two years showing that proteins from diverse, highly infectious virus families with zoonotic potential (e.g. Coronaviridae, Flaviviridae, Orthomyxoviridae) engage shared host pathways. We focus on two convergent mechanisms: (1) the activation of glial Toll-like receptor (TLR)4/TLR2 signaling, which initiates a chronic neuroinflammatory cascade, and (2) the disruption of host proteostasis, which seeds neurodegenerative proteinopathies like alpha-synuclein and tau aggregation. This framework positions post-viral syndromes as mechanistically related disorders and identifies pan-viral therapeutic targets, such as TLR inhibitors and autophagy activators."

However, most studies in NMR cells have relied on static biochemical or ultrastructural readouts, leaving the dynamic organisation of autophagy in living cells poorly defined. Here, we establish a stable tandem fluorescent autophagy reporter in NMR skin fibroblasts using an mCherry-EGFP-LC3NMR construct to enable live-cell, single-cell resolution analysis of ALP dynamics. Under basal conditions, NMR skin fibroblasts exhibit a greater abundance of LC3-positive structures than HeLa cells, together with a mixed population of autophagosomes and autolysosomes, indicating a distinct steady-state organisation of the ALP. Chloroquine (CQ)-induced lysosomal stress caused the expected accumulation of LC3-positive structures but also triggered the formation of large cytoplasmic vacuoles in NMR skin fibroblasts. Importantly, this vacuolation was not associated with acute cytotoxicity and progressively resolved following CQ removal, accompanied by reorganisation of LC3-positive compartments and recovery of lysosomal acidity. Electron microscopy showed that CQ-induced vacuoles are membrane-bound, containing internal material and co-existing with multiple ALP-related vesicular compartments. Primary NMR skin fibroblasts display a similar vacuolation phenotype, indicating that this response is not an artefact of immortalisation or reporter expression. Together, these findings establish a live-cell platform for analysing autophagy in NMR cells and identify a distinctive, reversible vacuolation response to lysosomal stress, consistent with dynamic remodelling of the lysosomal system within NMR skin fibroblasts."

Pathophysiological conditions in the cell cause the protein quality control system to depend on the autophagy-lysosome pathway (ALP) for degradation of accumulated misfolded proteins and mitochondrial turnover. BCL2-associated athanogene 3 (BAG3) protein has a role in initiating the ALP. Our aim was to ameliorate disease processes resulting from mitochondrial abnormalities and misfolded protein aggregation by upregulating the ALP through overexpression of human BAG3 (hBAG3). The VCP-A232E mouse, a model for hIBM, received AAVrh74.tMCK.hBAG3 systemically at 3 months of age, and outcome measures, including functional, histological, and molecular studies, were assessed 9 months post-gene delivery. hBAG3 treatment improved treadmill running distance and rotarod duration, reduced the number of TDP-43-positive aggregates, and decreased the number of fibers showing abnormalities in mitochondrial enzyme histochemistry, compared with the untreated cohort. Moreover, hBAG3 gene therapy resulted in improvements in mitophagy and mitochondrial homeostasis observed as increased levels in mitophagy markers Parkin and Bnip3, mitochondria biogenesis marker Pgc1\u03b1 and mitochondrial DNA-encoded subunits of complex IV, Cox1 and Cox3. In addition, the LC-II/I ratio increased, indicating increased autophagic flux.

However, whether GCGR directly confers renoprotection and the underlying mechanisms remain unclear. Here, using tubule-specific GCGR loss- and gain-of-function mouse models and human kidney samples, we show that tubular GCGR signaling exerts an important renoprotective role in DKD. Tubular GCGR expression is reduced in humans and mice with DKD and correlates with worse kidney function and increased renal injury. Genetic ablation of tubular GCGR markedly exacerbates DKD and induces pronounced phospholipid accumulation within enlarged lysosomes. Mechanistically, GCGR loss disrupts its association with the V-ATPase V1A subunit ATP6V1A, compromises V1-V0 assembly, and thereby impairs lysosomal acidification. This defect leads to impaired phospholipid hydrolysis and protease maturation, blockade of autophagic flux, and ultimately tubular cell injury. In vivo, ATP6V1A overexpression markedly reverses GCGR deficiency-induced lysosomal dysfunction and DKD progression. Consistently, re-expression of tubular GCGR via AAV9 restores lysosomal function, reduces phospholipid accumulation, and mitigates renal injury in DKD. Together, these findings provide genetic evidence for the renoprotective role of tubular GCGR in DKD, delineate a kidney-intrinsic GCGR-ATP6V1A-lysosome axis that protects tubular integrity, and extend prior GCGR-in-kidney observations into a more concrete GCGR-lysosome mechanism."

Although lysosomal dysfunction is closely associated with cellular aging, the role of V-ATPase in regulating lysosomal function during photoaging remains incompletely understood. By screening a V-ATPase-targeted siRNA library and validating the results using publicly available single-cell transcriptomic datasets, we identified ATP6V1A as a key regulator of UVB-induced cellular senescence. Furthermore, ATP6V1A knockdown exacerbated the UVB-induced cellular senescence and impaired lysosomal acidification and membrane integrity, whereas ATP6V1A overexpression effectively alleviated keratinocyte senescence, lysosomal dysfunction and autophagy inhibition. Moreover, treatment with the V-ATPase inhibitor BafA1 aggregated cellular senescence phenotype and autophagy inhibition and this phenomenon partially reversed by ATP6V1A overexpression.

Progranulin haploinsufficiency, a leading genetic cause of familial FTD, disrupts lysosomal function, lipid metabolism, autophagy, and neuroimmune signaling across multiple cell types. Increasing evidence indicates that microglia are particularly sensitive to progranulin loss, exhibiting elevated complement activation that contributes to TDP-43 proteinopathy and neuronal dysfunction. Here, we investigate the biological role of restoring progranulin exclusively within microglia by transplanting human induced pluripotent stem cell-derived microglial progenitors into progranulin (Grn)-deficient mice. We find that engraftment of wild-type, but not Grn-deficient, human microglia restore brain-wide progranulin levels, normalize microglial transcriptional states, and ameliorate pathological, functional, and behavioral phenotypes associated with progranulin loss. Because human microglia are the only source of progranulin in this system, these findings demonstrate that microglial progranulin is sufficient to restore key aspects of cellular, circuit, and behavioral homeostasis in a progranulin-deficient FTD model. More broadly, this work highlights a central, microglia-intrinsic role for progranulin in maintaining brain function and provides a framework for dissecting microglia-specific mechanisms across FTD and related neurodegenerative disorders."

The mitochondrial dysfunction is one of the primary sources of glial activation and dopaminergic neuron loss in Parkinson's disease (PD). The key biochemical elements of the pathogenesis of PD include impaired oxidative phosphorylation, elevated generation of reactive oxygen species (ROS), and impaired mitophagy. This review is a synthesis and stringent evaluation of recent experimental, clinical and genetic studies relating mitochondrial dysfunction and Parkinson's disease (PD). We examined information on bioenergetics, mitochondrial dynamics, calcium homeostasis, and interactions between neurons and glia. The molecular and therapeutic importance of therapies, such as mitophagy modulators, bioenergetic enhancers, and mitochondrial antioxidants, was investigated. The absence of Complex I, excess ROS, mitochondrial DNA damage, and nonfunctioning fusionfission cycles leads to neurodegeneration. The glial metabolic abnormalities worsen the oxidative stress and neuroinflammation, weakening the support of the neurons. The effects of impaired mitophagy are the accumulation of dysfunctional mitochondria, and the effects of calcium overload disrupt energy metabolism. Neuroprotective effects of such substances as spermidine, urolithin A, resveratrol, \u03b1lipoic acid, MitoQ, SkQ1, or CoQ10 have been shown using preclinical research. Sacrifices such as exercising and proper dieting enable the mitochondria to perform better and become stronger. Mitochondrial dysfunction enhances the progression of PD through oxidative stress, bioenergetic breakdown, and inflammatory signalling. Attention to these related systems is an entire way to alter the direction of a disease. PD can be treated using an increase in mitochondrial quality control, redox regulation, and metabolic efficiency. Continued studies in the framework of precision medicine are required to validate the safety and effectiveness of mitochondrial-targeted medications."

Over the past decade, a rapidly expanding literature has identified galectins as regulators of microglial activation, misfolded protein pathology, vesicle damage sensing, autophagy, synaptic plasticity, myelination, vascular repair, and neuroimmune communication. Galectins operate across intracellular and extracellular compartments to integrate cellular stress and innate immune signaling. Here, we review CNS studies of galectin-1, galectin-3, galectin-4, galectin-8, and galectin-9, focusing primarily on work published from 2019 onward while incorporating selected earlier studies to establish foundational concepts. Across experimental models and human studies, galectins orchestrate microglial state transitions, regulate aggregation and propagation of amyloid-\u03b2, tau, \u03b1-synuclein, and mutant huntingtin, and function as intracellular sensors of vesicle and lysosomal damage. Multiple studies further establish galectins as biomarkers and therapeutic targets across Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, stroke, traumatic brain injury, spinal cord injury, retinal degeneration, and chronic pain. Importantly, this review highlights a stage- and context-dependent paradox in which the same galectin axis can amplify neuroinflammation and proteopathic spread in some settings yet support recovery or tissue protection in others.

An emerging transcriptomic process that is also increasingly implicated in brain aging, neuroinflammation, and disease is the dysregulation of transposable elements (TEs), repetitive genomic sequences with the potential to cause cellular stress/dysfunction. However, there are limited data on microglial TE transcript patterns in these contexts. Here, we analyzed multiple RNA-seq datasets from isolated human and mouse microglia across aging, Alzheimer's disease (AD), and AD-associated pathology. In contrast to previous observations based on whole-brain tissue and other brain cell types, we found that microglial TE transcript levels remained relatively consistent throughout most of the human lifespan before increasing in late life. We also found that TE transcript levels in microglia from AD patients showed minimal changes compared to age-matched controls, and in RNA-seq analyses of transgenic AD mouse models we observed pathology-associated TE transcript decreases. Subsequent analyses identified inverse associations between TE transcript levels and autophagy/lysosome-related gene expression, and in\u00a0vitro studies suggested that aging- and AD-relevant stimuli, as well as pharmacological autophagy inhibition, modulate TE transcript expression in cultured human microglia. Together, these data provide novel insight into TE transcript dynamics in microglia, highlighting TE transcript patterns that differ from those observed in whole-brain samples and other cell types in aging and AD."

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n### [CLAIM EVALUATED AND ANSWER TO USER]\n\"Discovered Hypothesis: Spermidine-mediated autophagic activation may serve as an upstream regulator of lysosomal TMEM175 activity to prevent proteinopathy in C9orf72-ALS/FTD models.\"\n\nThe proposed hypothesis that spermidine-mediated autophagic activation functions as an upstream regulator of TMEM175 activity to prevent proteinopathy in C9orf72-ALS/FTD models is biologically plausible based on the convergence of identified cellular pathways; however, the provided literature lacks explicit experimental confirmation of a direct causal link between spermidine-induced autophagy and TMEM175 channel modulation. The dataset confirms that spermidine induces autophagy via EP300 inhibition and other mechanisms, and that TMEM175 dysregulation contributes to neurodegenerative pathogenesis, yet the two are not explicitly linked in the current corpus.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis of geroprotective polyamines and lysosomal ion channel regulation indicates that while both systems are critical for maintaining proteostasis, the specific regulatory axis connecting spermidine-driven autophagy to TMEM175-mediated lysosomal acidification in C9orf72-ALS/FTD pathology remains an unverified, albeit mechanistically sound, cross-talk intersection.\n\n### [INTRODUCTION & JUSTIFICATION]\nLysosomal dysfunction is recognized as a fundamental driver of neurodegenerative pathology. Spermidine, a dietary polyamine, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Autophagic pathways, including those maintained by the C9orf72/SMCR8 complex, are vital for microglial homeostasis and lysosomal repair. Simultaneously, TMEM175 serves as a lysosomal cation channel essential for maintaining lysosomal pH and function. Dysregulation of the autophagy-lysosomal pathway is a converging mechanism of pathology in C9orf72-associated diseases. While evidence indicates that pharmacological activation of autophagy can mitigate DPR accumulation and proteostatic stress in C9orf72 models, a direct regulatory relationship between spermidine and the TMEM175 channel remains a high-potential hypothesis for future investigation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   TMEM175 activity can be synergistically modulated, suggesting complex channel gating that might be responsive to metabolic states influenced by polyamines.\n*   The C9orf72/SMCR8 complex maintains microglial homeostasis via RAB8A-ESCRT-mediated lysosomal repair, providing a structural repair mechanism distinct from, yet likely coordinated with, macroautophagy.\n*   Lysosomal membrane damage acts as a specific trigger for ATG8-conjugation, indicating that membrane integrity and ionic flux are tightly coupled through the endo-lysosomal-lipid axis.\n*   The same galectin axis can amplify neuroinflammation and proteopathic spread in some settings yet support recovery or tissue protection in others, highlighting the context-dependency of lysosomal quality control.\n*   Protein-layer-dominant autophagy-lysosome remodelling is a feature of dermal fibroblast ageing, suggesting that post-transcriptional control of lysosomal capacity may precede transcriptional changes in systemic aging.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This narrative review examines four mechanistically distinct compounds, namely spermidine, fisetin, berberine, and urolithin A, as emerging functional food ingredients with scientifically supported effects on key hallmarks of human aging. Spermidine, a dietary polyamine from wheat germ and fermented foods, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Fisetin, a flavonoid from strawberries and apples, exerts senolytic activity by selectively eliminating senescent cells via PI3K/AKT and Bcl-2/Bcl-xL inhibition, with emerging clinical evidence. Berberine, an isoquinoline alkaloid from Berberis species, modulates metabolic dysfunction via AMP-activated protein kinase (AMPK) activation and reshapes gut microbiota composition through direct high intraluminal exposure, with the most extensive clinical dataset of the four compounds. Urolithin A, a gut microbiome-derived postbiotic from ellagitannins in pomegranates and nuts, induces mitophagy via PINK1/Parkin and has been evaluated in a growing number of registered human clinical trials. Together, the four compounds primarily target distinct but complementary aging-associated pathways (autophagy, senolysis, metabolic regulation, mitophagy), suggesting rational potential for combined functional food formulations. Limited direct evidence for their combined use and the need for dedicated co-administration studies are discussed, alongside bioavailability, safety, and regulatory considerations.\n\nID: 42555669\nTitle: Glial cell toxicity in a Drosophila C9orf72 neurodegeneration model.\nAbstract: The most common genetic cause of both familial amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) is an expanded G4C2 repeat in the first intron of the gene C9orf72. The C9orf72 repeat expansion is bidirectionally transcribed into sense and anti-sense RNA foci, and also produces dipeptide repeats (DPRs) via a non-canonical translation mechanism known as repeat-associated (RAN) translation. Each of these components of the G4C2 repeat expansion cause neurodegenerative effects in animal models when expressed in neurons, but impacts from glial expression are more poorly understood. Here, we use glial cell type-specific expression of individual DPRs, of RNA repeat-only, or of the G4C2 repeat, that produces both DPRs and RNA repeats, to systematically investigate glial toxicity of each component. We find that as with neurons, the GR and G4C2 transgenes produce the highest degree of toxicity when expressed in glia. Each of these transgenes are capable to produce the GR DPR, which also is the most toxic factor in neurons. We demonstrate that both the GR and G4C2 transgenes cause activation of mdg4, an endogenous retrovirus (ERV). Such ERV expression is a hallmark of TDP-43 dysfunction that is commonly observed in C9orf72 patients. We find that glial expression of either the GR or the G4C2 transgene is toxic to glial cells, but such expression does not cause loss nearby neurons. However, blocking apoptotic signaling within glia that express either GR or G4C2 via expression of the p35 caspase inhibitor further exacerbates effects on lifespan and ablating such glia via expression of the proapoptotic reaper gene partially ameliorates these effects. Together, these results indicate that expression of toxic C9orf72 components in glia produces deleterious effects on lifespan, though potentially through different mechanisms than seen in TDP-43 models of ALS/FTD.\n\nID: 42549514\nTitle: Facilitation of Autophagosome-Lysosome Fusion by LAPTM4A: A Novel Strategy for Attenuating Myocardial Ischemia-Reperfusion Injury.\nAbstract: Myocardial ischemia-reperfusion (MIR) injury compromises therapeutic effects of revascularization and leads to functional impairment and exacerbation of structural damage in the heart. Limiting the damage caused by MIR is crucial but is still an unmet clinical need because of the complexity of the underlying mechanisms. Increasing evidence suggests that lysosomal autophagy plays a significant regulatory role in MIR injury. The specific mechanisms involved remain to be fully understood. We here systematically analyzed the murine MIR model database to screen the potentially protective lysosome-localized proteins against MIR injury. The positive hits were further functionally screened and validated for their capability on autophagy and hypoxia/reoxygenation insults of cardiomyocytes. After exploring the detailed molecular mechanism underlying the protective effects of the target protein, we generated target gene cardiac-specific knockout mice and overexpression mice to verify its function in mouse MIR injury models. LAPTM4A (lysosome-associated protein transmembrane 4 alpha) stood out as a significant protective lysosome-localized protein from the screening. LAPTM4A deficiency significantly heightened the inflammatory response and cell death both in primary cardiomyocytes and in a MIR-induced mouse model. Conversely, LAPTM4A overexpression exerted protective effects on cell viability and myocardial damage. Mechanistically, LAPTM4A interacts with Rubicon (Run domain Beclin1-interacting and cysteine-rich domain-containing protein), hindering its engagement within the Beclin1 complex, resulting in a robust augmentation of autophagic flux and thereby mitigating cardiac damage during reperfusion. It is important to note that Rubicon knockdown markedly reversed the aggravated injury induced by LAPTM4A knockdown, further verifying the effects of LAPTM4A depend on Rubicon. Our findings screened out and validated that LAPTM4A is a lysosome-localized protein exerting protective effects against MIR injury by facilitating autophagic flux. Targeting LAPTM4A represents a promising therapeutic strategy for mitigating MIR injury.\n\nID: 42546981\nTitle: New insights on microglial lysosomal acidification: A therapeutic target of neurodegenerative diseases.\nAbstract: Microglia, the resident immune cells of the central nervous system (CNS), maintain brain homeostasis and respond to pathological insults. Microglial dysfunction has been implicated in the pathogenesis of several neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and multiple sclerosis. Impaired lysosomal function, particularly defective lysosomal acidification, leads to the accumulation of undegraded material, thereby promoting neuroinflammation and neuronal damage. This review examines the mechanisms governing lysosomal acidification in microglia and evaluates its potential as both a therapeutic target and a prognostic biomarker in neurodegenerative diseases. The literature on microglial lysosomal acidification, lysosomal pH regulation, autophagy, and neurodegeneration was searched in PubMed, Scopus, and Web of Science. Relevant mechanistic, preclinical, and translational studies were critically appraised and synthesized. Lysosomal acidification is increasingly recognized as a key regulator of microglial function and homeostasis. Defective acidification, driven by dysregulation of the vacuolar H+-ATPase (V-ATPase) proton pump, TFEB/TFE3 signaling pathways, and lysosomal ion channels such as TRPML1 and TMEM175, impairs autophagic flux and substrate degradation, facilitating the accumulation of neurotoxic aggregates including amyloid-\u03b2 and \u03b1-synuclein. Emerging evidence suggests that the degree of microglial lysosomal acidification may serve as a prognostic biomarker for disease progression and therapeutic response. Restoration or enhancement of lysosomal acidification through pharmacological modulation of lysosomal pH, activation of autophagy, or targeting of key regulatory pathways has been shown to re-establish microglial homeostasis, attenuate neuroinflammation, and confer neuroprotection in preclinical models. Restoration of microglial lysosomal acidification represents a promising therapeutic strategy for neurodegenerative diseases. A deeper understanding of the molecular mechanisms regulating lysosomal acidification in microglia may facilitate the identification of novel biomarkers and therapeutic targets, ultimately contributing to the development of innovative interventions for neurodegenerative disorders.\n\nID: 42538987\nTitle: GENETIC AND PHARMACOLOGIC ACTIVATION OF BECLIN1 PREVENTS ALDOSTERONE-INDUCED CARDIOVASCULAR DAMAGE.\nAbstract: Aldosterone promotes endothelial dysfunction and cardiovascular injury through mineralocorticoid receptor (MR) activation. Autophagy is essential for endothelial homeostasis, yet its role in aldosterone-mediated vascular dysfunction remains unclear. We tested whether aldosterone impairs autophagic flux and whether restoring autophagy via Beclin1 (BCN1) activation protects vascular and cardiac function. Endothelial and vascular responses to aldosterone were assessed in wild-type mice, BCN1 gain-of-function mice (Becn1), and mice treated with spermidine or a BCN1-activating TB-peptide. Vascular function, nitric oxide (NO)/reactive oxygen species (ROS) production, autophagy markers, endothelial migration, and cardiac fibrosis were evaluated using wire myography, fluorescence assays, Western blotting, confocal microscopy, migration assays, and histology. Aldosterone impaired endothelium-dependent relaxation, decreased NO, increased ROS, and disrupted autophagic flux in an MR-dependent manner, indicated by LC3 accumulation and reduced p62 and BCN1 expression. Spermidine restored endothelial function and normalized NO and ROS levels. BCN1 gain-of-function mice were protected from aldosterone-induced endothelial dysfunction and exhibited reduced coronary and myocardial fibrosis. TB-peptide activation of BCN1 enhanced autophagic flux, improved vascular function, decreased cardiac fibrosis, and rescued endothelial migration impaired by aldosterone. Aldosterone induces endothelial dysfunction by suppressing autophagic flux through MR activation. Genetic or pharmacologic enhancement of BCN1-dependent autophagy restores endothelial homeostasis and prevents vascular and cardiac injury, identifying autophagy activation as a promising therapeutic approach for cardiovascular diseases associated with mineralocorticoid excess.\n\nID: 42523377\nTitle: Single-cell transcriptomic atlas of frontoinsular cortex reveals molecular correlates of selective neuronal vulnerability in FTD.\nAbstract: Frontotemporal dementia (FTD) is characterized by selective neuronal vulnerability, yet the features that predispose specific neuron types to degeneration remain unclear. We performed single-nucleus RNA sequencing of frontoinsular cortex, a region affected early in behavioral variant FTD, across individuals with C9orf72-associated and sporadic FTD-MND spectrum disease. By enriching for large projection neurons, we resolved molecular subtypes of layer 5 extratelencephalic neurons, including von Economo neurons, and identified selective depletion of specific layer 2/3 and layer 5 neuron subtypes, convergent across genotypes. Despite selective neuronal loss, disease-associated transcriptional changes were convergent across excitatory neuron populations, suggesting that they reflect upstream pathophysiology or shared responses to local neurodegeneration. By relating neighborhood-level depletion in disease to gene expression in controls, we found that baseline cellular respiration and ATP synthesis predict neuronal vulnerability in disease. These findings define molecular correlates of selective neuronal vulnerability in FTD and provide a framework linking cell type and state to neurodegeneration.\n\nID: 42506061\nTitle: Protein-First, but Not Protein-Only: Rethinking Neurodegenerative Diseases Through Transgenic Mouse Models.\nAbstract: Neurodegenerative diseases represent a major and growing global health burden. Although these disorders are often clinically defined by symptoms and affected brain regions, many are mechanistically linked to abnormal protein accumulation, misfolding, impaired proteostasis, RNA dysregulation, mitochondrial dysfunction, and neuroinflammation. In this Perspective article, I discuss major neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, dementia with Lewy bodies, multiple system atrophy, amyotrophic lateral sclerosis, frontotemporal dementia, Huntington's disease, prion diseases, spinocerebellar ataxias, and spinal muscular atrophy, through the lens of disease-associated proteins and experimental modeling. I argue that a protein-centered framework provides a useful approach for understanding disease mechanisms and selecting transgenic mouse models, while recognizing that aging, cellular context, neuroinflammation, mitochondrial dysfunction, vascular dysfunction, and other disease modifiers also shape neurodegeneration. Transgenic and genetically engineered mouse models have been essential for dissecting the pathogenic roles of amyloid-\u03b2, tau, \u03b1-synuclein, TDP-43, SOD1, FUS, C9ORF72-associated dipeptide repeat proteins, mutant huntingtin, prion protein, ataxins, and SMN deficiency. However, these models have important limitations, including artificial overexpression, familial mutation bias, species differences, and incomplete representation of aging-related sporadic diseases. Rather than seeking a single \"best\" model, a more productive strategy is to adopt model portfolios tailored to specific biological questions and to integrate mouse studies with human cellular models, postmortem tissue, omics approaches, and biomarker-based validation. Such an approach may improve mechanistic insight, strengthen translational relevance, and enhance the predictive value of preclinical neurodegenerative disease research.\n\nID: 42489267\nTitle: A Blood-Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN-Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1.\nAbstract: Peripheral factors that systemically regulate amyotrophic lateral sclerosis (ALS) have remained elusive-until now. Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy.\n\nID: 42477140\nTitle: Mitochondrial-derived vesicles drive budding-type fission of damaged lysosomes.\nAbstract: Lysosomes are central degradative organelles essential for cellular homeostasis, yet the mechanisms that maintain their integrity and function under stress remain incompletely understood. Here we identify a previously unrecognized lysosomal renewal process, termed budding-type fission (B-fission), which restores lysosomal function during hypoxia-reoxygenation stress. During B-fission, damaged lysosomes generate membrane buds that undergo scission to form small, fully functional lysosomes, independently of autophagic lysosome reformation. Mechanistically, mitochondrial-derived vesicles (MDVs) deliver the fission adaptor MFF to lysosomes, where MFF recruits the dynamin-related GTPase DRP1 to drive membrane scission. MIRO2 promotes the formation of MFF+ MDVs through direct interaction with MFF, while the lysosomal membrane protein ITM2C binds MIRO2 to tether and guide MFF+ MDVs to lysosomes, enabling efficient MFF delivery and subsequent B-fission. Notably, AMPK activation by 991 or metformin promotes MFF-dependent lysosomal B-fission under normoxic conditions, whereas AMPK inhibition by dorsomorphin suppresses B-fission during hypoxia-reoxygenation. This stress-responsive ITM2C-MIRO2-MFF-DRP1 axis co-opts the mitochondrial division machinery to drive lysosomal fission from damaged lysosomes, thereby enabling the undamaged components to reorganize into daughter lysosomes and promote lysosomal renewal. Thus, our findings uncover a fundamental mode of lysosomal renewal and reveal an unexpected role for MDV-mediated mitochondria-lysosome communication in mediating lysosomal quality control during ischaemia-reperfusion and related stresses.\n\nID: 42468217\nTitle: Spermidine alleviates 2,2-dichloroacetamide/ 2,2-dibromoacetamide-exposed mouse oocyte toxicity by restoring autophagic homeostasis.\nAbstract: Environmental toxicants pose a major threat to human health, yet the reproductive toxicity of haloacetamide disinfection byproducts remains largely unclear. Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application.\n\nID: 42458926\nTitle: The gut microbiota-metabolome axis mediates the adaptive protective effects of a high-altitude probiotic against distinct aging etiologies.\nAbstract: Aging is a major driver of chronic diseases and mortality, yet effective interventions against distinct aging etiologies remain limited. Hypobaric hypoxia at high altitudes accelerates aging, while D-galactose (D-gal) injection mimics metabolic aging. The gut microbiota is a key regulator of aging, but whether indigenous probiotics from the high plateaus of Tibet exert comparable or differential efficacy against distinct aging etiologies remains unclear. In this study, we systematically evaluated the protective effects of Lactiplantibacillus plantarum AL4510, a novel probiotic strain isolated from traditional fermented goat milk on the Qinghai-Tibet Plateau. We used both D-gal-induced and hypobaric hypoxia-induced aging models established simultaneously within the same experimental system. AL4510 significantly alleviated oxidative stress in both models, as evidenced by restored serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reduced malondialdehyde (MDA) levels. Systemic inflammation was attenuated, with lower interleukin-1\u03b2 (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1) concentrations. Cellular senescence, assessed using senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) and p16 immunofluorescence, was markedly reduced in both liver and colon tissues by approximately 50-60%. The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovibrio, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculum, and Lactobacillus. Metabolomic profiling revealed that AL4510 replenished short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate in both models, indicating restoration of gut fermentative capacity. Importantly, AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4; in the hypoxia model, it upregulated neuroprotective catalpol, lupeol, and energy-related calcium pantothenate. Integrative correlation and co-occurrence network analyses suggested that AL4510 was associated with a beneficial microbial consortium that correlated with host metabolism potentially involving the microbiota-SCFA axis. Collectively, these findings suggest that AL4510 exerts broad spectrum anti-aging effects potentially involving a \"dual-track\" mechanism: convergent restoration of gut ecological balance and divergent, stress-adapted reprogramming of host metabolism. This study provides a scientific basis for developing AL4510 as a functional probiotic ingredient or postbiotic formulation for high-altitude adaptation, metabolic anti-aging interventions, and gut-targeted nutritional strategies.\n\nID: 42454709\nTitle: MAP1S limits autoimmune uveitis by suppressing Th17 differentiation through dual Control of the EGR2-LCN2 axis and autophagic flux.\nAbstract: Autoimmune uveitis is a vision-threatening inflammatory disorder driven by dysregulated T helper 17 (Th17) responses, yet therapeutic strategies targeting Th17 differentiation are lacking. Through transcriptomic screening of an experimental autoimmune uveitis (EAU) model and validation in peripheral blood mononuclear cells from Vogt-Koyanagi-Harada patients, we identified MAP1S (microtubule-associated protein 1S) as a pivotal, conserved regulator. Here, we demonstrate that MAP1S constrains pathogenic Th17 responses and alleviates EAU through a dual mechanism coordinating transcriptional control and autophagic degradation. Mechanistically, MAP1S binds to EGR2 (early growth response 2) and restrains its acetylation at Lys368, thereby suppressing Lcn2 (lipocalin 2) transcription. Besides, MAP1S facilitates autophagosome biogenesis and lysosomal trafficking, promoting the autophagic clearance of LCN2 protein. Notably, MAP1S deficiency enhances EGR2 acetylation, increases Lcn2 transcription, disrupts autophagosome trafficking, impairs LCN2 degradation, and promotes LCN2 accumulation, collectively driving Th17 polarization and exacerbating EAU pathology. Adoptive transfer of cervical lymph node cells from map1s knockout mice reproduced severe disease in wild-type recipients. Moreover, pharmacological activation of MAP1S with spermidine suppressed Th17 responses and alleviated disease severity. Our findings establish MAP1S as a critical node integrating acetylation signaling of EGR2 and autophagic flux to govern LCN2\u00a0homeostasis and Th17 pathogenicity, revealing a promising therapeutic target for autoimmune uveitis and potentially other Th17-mediated diseases.Abbreviations: AAV: adeno-associated virus; ACOD1: aconitate decarboxylase 1; AU: autoimmune uveitis; BCL2: B cell leukemia/lymphoma 2; CDLNs: cervical draining lymph nodes; CFA: complete Freund's adjuvant; ChIP: chromatin immunoprecipitation; Co-IP: co-immunoprecipitation; CQ: chloroquine; EAU: experimental autoimmune uveitis; EGR2: early growth response 2; GDF15: growth differentiation factor 15; HDAC4: histone deacetylase 4; HDAC6: histone deacetylase 6; IL17: interleukin 17; IL17f: interleukin 17f; IL22: interleukin 22; K: lysine; KAT2A/GCN5: K(lysine) acetyltransferase 2A; KO: knockout; LCN2: lipocalin 2; MAP1LC3/LC3: microtubule-associated protein 1 light chain 3; MAP1S: microtubule-associated protein 1S; MS: mass spectrometry; PBMC: peripheral blood mononuclear cell; PCR: polymerase chain rection; PPI: protein-protein interaction; PTX: pertussis toxin; qPCR: quantitative PCR; RT-qPCR: reverse transcription and quantitative real-time RCR; SAA3: serum amyloid A3; SPD: spermidine; Th1 cells: T helper 1 cells; Th17 cells: T helper 17 cells; TF: transcriptional factor; Tregcells: regulatory T cells; VKH disease: Vogt-Koyanagi-Harada disease; WT: wild-type.\n\nID: 42444672\nTitle: Polyamine-mediated inhibition of ferroptosis contributes to geroprotection.\nAbstract: Geroprotection aims at extending healthspan by delaying age-associated pathologies. Polyamines including spermine and spermidine are interconvertible metabolites whose longevity-promoting effects have traditionally been attributed to autophagy induction. In addition, recent evidence identifies spermine as an endogenous Fe2+ chelator that suppresses ferroptosis, thereby complementing the autophagy-inducing activity of spermidine. Indeed, spermidine inhibits EP300 acetyltransferase activity and supports hypusination-dependent activation of TFEB, both leading to autophagy. However, enhanced autophagic flux may increase susceptibility to ferroptosis through ferritinophagy and lipid remodeling. In parallel, polyamine catabolism generates H2O2 and acrolein, both of which facilitate lipid peroxidation and ferroptotic demise. The discovery that spermine directly chelates redox-active Fe2+ closes a conceptual gap by explaining how polyamine supplementation can promote longevity while avoiding excessive ferroptotic cell loss. Multiple lines of evidence including metabolomics, isotope tracing, cell-free lipid peroxidation systems, Fe2+-binding biophysics, mass spectrometry, Raman spectroscopy, nuclear magnetic resonance and disease models demonstrate that spermine limits labile iron and ferroptosis. Together, these findings support a unified model in which spermidine-driven autophagy and spermine-mediated ferroptosis inhibition cooperate to preserve tissue homeostasis and healthspan.\n\nID: 42406105\nTitle: Agmatine induces mitophagy via the PTS-I2R pathway to increase autophagic flux and attenuate sepsis-induced intestinal epithelial cell apoptosis.\nAbstract: The therapeutic options for sepsis-induced intestinal injury, which drives multiple organ dysfunction and mortality, are limited, but the role of polyamine supplements remains unclear. This study aimed to elucidate the protective effect of agmatine (AGM) on sepsis-induced intestinal injury and its mitochondrial-targeted antiapoptotic mechanism in intestinal epithelial cells (IECs). We verified the transport and subcellular localization of AGM in IECs via fluorescence assays and established in vitro and in vivo IEC apoptosis models. Functional evaluations using cell viability assays, laser confocal imaging, flow cytometry, transmission electron microscopy, and multiomics techniques were performed. AGM attenuated sepsis-induced intestinal injury, as evidenced by its ability to lower the serum levels of intestinal damage markers in septic mice, attenuate inflammatory factor production and pathological damage in the intestine, and reduce IEC apoptosis. AGM entered IECs via the polyamine transport system (PTS), but not the NMDA receptor, and inhibited IEC apoptosis induced by TNF\u03b1/CHX or TNF\u03b1/ActD. Notably, AGM exerted its antiapoptotic effect by targeting the mitochondrial imidazoline I2 receptor (I2R). Mechanistically, AGM induced mitophagy by decreasing the mitochondrial membrane potential without altering mitochondrial number or function, as ROS production, calcium ion influx, ATP generation, and oxygen consumption were unchanged. AGM also increased autophagic flux, as confirmed upon treatment with various autophagy inhibitors. AGM alleviates sepsis-induced intestinal injury via the PTS-I2R axis by promoting mitophagy and autophagic flux to inhibit IEC apoptosis, laying a foundation for the use of AGM as a potential nutritional supplement or therapeutic agent for sepsis-induced intestinal injury.\n\nID: 42392052\nTitle: Psychological stress drives aging-like hematopoietic stem cell dysfunction through a brain-gut-bone marrow axis.\nAbstract: Chronic stress influences hematopoietic stem cells (HSCs). However, how psychological stress regulates HSC function remains incompletely understood. Here, we show that psychological stress impairs HSC self-renewal and lymphoid differentiation, inducing aging-like phenotypes. Stress suppresses neuronal activity in the medial prefrontal cortex (mPFC) and periaqueductal gray (PAG), leading to HSC dysfunction, whereas chemogenetic activation of these regions restores HSC function. Psychological stress or chemogenetic inhibition of the mPFC and PAG reduces the abundance of L. reuteri in the gut microbiota and lowers spermidine levels. Mechanistically, spermidine depletion suppresses mitochondrial autophagy, promotes mitochondrial peroxidative stress, and increases ferroptotic stress in HSCs. We further demonstrate that mPFC and PAG activity regulate the intestinal environment through a sympathetic pathway, reducing intestinal mucin levels, L. reuteri abundance, and spermidine levels. These findings identify a brain-gut-bone marrow axis linking psychological stress to aging-like HSC dysfunction through sympathetic regulation of intestinal microbiota and spermidine metabolism.\n\nID: 42389983\nTitle: A nonhydrolyzable candesartan cilexetil analog reveals synergistic activation as a tractable mechanism for TMEM175 modulation.\nAbstract: TMEM175 is a lysosomal cation channel essential for maintaining lysosomal pH and function. Dysregulation of TMEM175 has been implicated in Parkinson's disease, highlighting the need for small-molecule modulators to probe its physiological and therapeutic roles. We previously screened an FDA-approved compound library for TMEM175 modulators using a plasma membrane overexpression system that enables functional analysis of channel activity. Here, we report the pharmacological characterization of the most potent hit, candesartan cilexetil. In fluorescence-based thallium flux, automated patch-clamp, and manual patch-clamp assays, candesartan cilexetil robustly activates TMEM175 with efficacy comparable with the reference activator DCPIB, whereas its hydrolyzed metabolite candesartan is inactive. Candesartan cilexetil is active only when applied to the extracellular (lysosome lumen-equivalent) side of the channel and is inactive from the cytosolic-facing side. To determine whether activation requires the intact prodrug, we generated analogs that modify or eliminate the cilexetil and ester functionalities. Structure-activity studies show that selected modifications of the cilexetil moiety reduce potency while preserving maximal efficacy, whereas more extensive modification markedly reduces intrinsic activity, indicating that it is an essential pharmacophoric element rather than a simple membrane-permeating handle. Manual patch-clamp wash-off experiments further demonstrate direct, reversible activation without requiring membrane permeation or hydrolysis. Unexpectedly, the nonhydrolyzable analog VU0982645 exhibits minimal intrinsic activity yet produces robust synergistic activation with DCPIB. Together, these findings establish the cilexetil handle as a key pharmacophoric element and support synergistic modulation as a tractable mechanism for activating TMEM175.NEW & NOTEWORTHY We introduce a new therapeutic paradigm for TMEM175 targeting by demonstrating that synergistic agonist pairs can drive robust channel activation. Beyond identifying candesartan cilexetil as a moderately potent activator with a previously unrecognized pharmacophoric cilexetil moiety, we show that a minimally active analog can dramatically potentiate activation in combination with DCPIB. This synergistic strategy establishes TMEM175 as a tractable therapeutic target and reveals coagonism as a powerful mechanism to modulate lysosomal ion channels.\n\nID: 42388895\nTitle: FTLD-TDP versus LATE-NC: Experience of a Brain Bank specializing in FTLD-TDP.\nAbstract: Similarities between frontotemporal lobar degeneration with transactive response DNA-binding protein of 43\u00a0kDa (TDP-43) (FTLD-TDP) and limbic-predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) raise questions about whether they represent distinct entities or a single disease spectrum. The literature mostly examined series with disproportionate numbers of LATE-NC over FTLD-TDP. Leveraging a clinicopathological collection of FTLD-TDP (N\u00a0=\u00a0148) from the University of California, San Francisco, we compared demographic, clinical, genetic, and neuropathological features of FTLD-TDP, particularly FTLD-TDP type A (N\u00a0=\u00a039), and LATE-NC (N\u00a0=\u00a042). FTLD-TDP type A cases were younger at onset and death, had shorter disease duration, and frequent genetic causes (GRN, C9ORF72) compared to LATE-NC, which were mostly sporadic and older. Blinded evaluation of middle frontal gyrus (MFG) TDP-43 immunostaining alone proved insufficient to reliably differentiate FTLD-TDP type A from LATE-NC stage 3. However, factoring in all neuropathologic features, FTLD type A and LATE-NC could be differentiated with\u00a0>95% confidence. These overall findings support distinct diagnostic entities for FTLD-TDP and LATE-NC.\n\nID: 42385702\nTitle: Recurrent patterns of TOP1-mediated neuronal genomic damage shared by major neurodegenerative disorders.\nAbstract: Amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer's disease (AD) represent two major categories of neurodegenerative disorders-TAR DNA-binding protein 43 (TDP-43) and tau proteinopathies-for which the mechanisms driving neuronal death remain unclear. Single-cell whole-genome sequencing of 469 neurons from C9ORF72 ALS, C9ORF72 FTD, AD, and control brains revealed increased somatic single-nucleotide variants (sSNVs) and insertions/deletions (sIndels) in all three diseases. Mutational signature analysis identified a disease-associated sSNV signature consistent with oxidative damage and an sIndel process affecting 22% of ALS, 76% of FTD, and 61% of AD neurons-but only 2% of control neurons-resembling signature ID4, previously linked to topoisomerase 1 (TOP1)-mediated mutagenesis. Rapid approach to DNA adduct recovery (RADAR) assays confirmed increased TOP1-DNA covalent complexes, and duplex sequencing confirmed the increased sIndels and identified single-strand events as likely precursor lesions. TOP1-associated sIndel mutagenesis and genome instability thus represent a mechanism shared by both TDP-43 and tau neurodegeneration.\n\nID: 42378850\nTitle: Spermidine mitigates glucocorticoid-induced bone osteoporosis by targeting oxidative stress and RANKL/OPG pathway.\nAbstract: Glucocorticoid-induced osteoporosis (GIOP) is one of the most prevalent types of osteoporosis. This disorder is linked to a high disability and morbidity rate, highlighting the critical need for better preventative and treatment techniques. Spermidine (SPD), a naturally occurring polyamine, modulates critical biological activities, including cell proliferation, autophagy, aging, oxidative stress, and inflammation, and has bone-protective properties. The present study investigated whether SPD could attenuate bone loss in a GIOP rat model. Four groups were created: control, SPD (20\u202fmg/kg), dexamethasone (DEX) (7\u202fmg/kg intramuscularly injected once a week for 5 weeks), and DEX\u202f+\u202fSPD. DEX administration significantly disrupted bone homeostasis, as evidenced by decreased osteocalcin levels, elevated C-telopeptide of type I collagen (CTX-1), upregulated receptor activator of nuclear factor kappa-\u03b2 ligand (RANKL) expression, downregulated runt-related transcription factor 2 (RUNX2) and osteoprotegerin (OPG) expression, elevated oxidative stress (increased malondialdehyde and depleted reduced glutathione), and heightened pro-inflammatory cytokines. These biochemical alterations were accompanied by significant deterioration in bone morphometric parameters. Spermidine co-administration markedly attenuated these changes, restoring redox balance, suppressing inflammatory mediators, modulating the RANKL/OPG axis, and partially preserving bone microarchitecture. These findings indicate that SPD shows beneficial effects in safeguarding against GIOP in a rat model, providing a foundation for further preclinical and clinical investigations.\n\nID: 42362467\nTitle: Metabolic control of RNA splicing by polyamines.\nAbstract: Polyamines are ancient metabolites that support growth, translation, and autophagy. Zabala-Letona et al. reveal a new mode of action-'metabolic shielding'-in which polyamines protect phosphorylation motifs in spliceosomal factors. This work links polyamines, for the first time, to alternative splicing, raising new questions for cancer, aging, and beyond.\n\nID: 42359357\nTitle: Innate immune crosstalk in ALS/FTD pathogenesis.\nAbstract: Marked by protein aggregation, impaired proteostasis, organelle stress, and chronic neuroinflammation, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) form a clinically, genetically, and pathologically overlapping disease spectrum. Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression. In this review, we elaborate on how ALS/FTD-associated genetic lesions and pathogenic protein aggregates, including TDP-43, SOD1, FUS, and C9orf72-derived dipeptide repeat proteins, engage three interconnected innate immune pathways: cGAS-STING, NLRP3 inflammasomes, and TREM2-DAP12 signaling. We further highlight emerging crosstalk among these pathways, in which cGAS-STING and NLRP3 reinforce inflammatory signaling, while NLRP3-driven TREM2 shedding may impair microglial clearance and perpetuate proteostatic failure. Understanding this immune network may help define disease subtypes, identify biomarkers, and guide combinatorial therapeutic strategies that suppress harmful inflammation while preserving protective microglial functions.\n\nID: 42358231\nTitle: Spermidine in Alzheimer's Disease: Evidence from Animal Models and Human Studies.\nAbstract: Spermidine is a naturally occurring polyamine involved in multiple cellular processes, including growth regulation, protein translation, and autophagy. Increasing attention has been devoted to its potential neuroprotective effects, particularly in Alzheimer's disease (AD), a neurodegenerative disorder characterized by \u03b2-amyloid and phosphorylated tau accumulation, synaptic dysfunction, and progressive neuronal loss. In this narrative review, we examine potential mechanisms through which spermidine may influence AD pathophysiology and summarize available preclinical and clinical evidence. Preclinical studies indicate that spermidine induces autophagy, a key cellular clearance pathway responsible for removing damaged organelles and aggregated proteins. Because impaired neuronal autophagy contributes to the accumulation of \u03b2-amyloid and tau in AD, increasing intracellular spermidine levels may enhance the degradation of these toxic species. In addition, spermidine exhibits anti-inflammatory and antioxidant properties, attenuates microglial activation, and supports mitochondrial function. In animal models of AD and brain aging, spermidine administration has been associated with improvements in cognitive performance and synaptic function. However, human clinical evidence remains limited and largely inconclusive. Observational studies suggest associations between higher dietary spermidine intake and better cognitive outcomes, but do not establish causality. Randomized clinical trials to date are few, include small and heterogeneous populations, and have not demonstrated consistent effects on primary cognitive endpoints. Overall, spermidine represents a biologically plausible modulator of pathways relevant to neurodegeneration, but translation of preclinical findings into clinical benefit remains uncertain. Current evidence is insufficient to support its use as a therapeutic or preventive intervention in AD, and further well-designed clinical studies are required to clarify its efficacy and mechanisms of action. Alzheimer\u2019s disease is one of the most common causes of memory loss in older adults. Researchers are searching for ways to protect brain cells and slow the biological processes that lead to this disease. One molecule that has recently attracted attention is spermidine, a natural compound found in all living cells and in many foods, including whole grains, legumes, mushrooms, and aged cheeses. Spermidine plays several roles in the body. One of its most important effects is activation of autophagy, a natural cellular process that removes damaged proteins and other cellular waste. This process is relevant to Alzheimer\u2019s disease because the condition is associated with the accumulation of abnormal proteins in the brain. Experimental studies also suggest that spermidine may influence inflammation in the brain, support mitochondrial function (the energy system of cells), and help maintain communication between nerve cells. In this review, we summarized evidence from laboratory experiments, animal studies, and available human research. In animal models of brain aging and Alzheimer\u2019s disease, spermidine consistently shows neuroprotective effects and can improve memory performance. Human evidence is more limited. Observational studies suggest that higher dietary spermidine intake may be associated with better cognitive performance, while clinical trials investigating supplementation have produced mixed results. Spermidine is naturally present in many foods and is increasingly studied in the context of aging and brain health. Overall, current evidence suggests that spermidine may play a role in brain aging. Larger and well-designed clinical studies are needed to clarify its potential relevance for Alzheimer\u2019s disease.\n\nID: 42348055\nTitle: Clinical and literature insights into the frontotemporal dementia and motor neuron disease spectrum.\nAbstract: Frontotemporal dementia represents a heterogeneous group of neurodegenerative disorders primarily affecting the frontal and temporal lobes. The overlap between FTD and motor neuron disease is increasingly recognized, presenting a complex clinical syndrome characterized by progressive cognitive, behavioral, and motor decline. We describe a 69-year-old patient with a 4-year history of excessive ambulation. Over the last year, behavioral changes including disorganized conduct, irritability, spitting, and cold water foot immersion developed. The patient experienced compelling auditory hallucinations driving her to walk continuously for up to 10 h per day. Four months prior to admission, gait impairment with frequent falls, along with hyperorality developed. Neurological examination revealed asymmetric mild weakness, marked muscle atrophy of facial and limb muscles, hyperreflexia, and impaired postural control. Brain MRI showed diffuse cerebral atrophy; electrophysiological studies indicated probable motor neuron disease; and TRODAT SPECT demonstrated impaired presynaptic dopaminergic function bilaterally, consistent with parkinsonism. Final diagnosis was frontotemporal dementia with probable motor neuron disease. A review of the literature highlights the clinical, radiological, and molecular features of FTD-MND overlap, emphasizing the role of TDP-43 pathology, C9orf72 mutations, and the need for multidisciplinary management. Current strategies are symptomatic, though novel therapies such as antisense oligonucleotides and biomarkers like neurofilament light chain (NfL) show promise. This case highlights the diagnostic complexity of FTD with MND overlap syndrome, emphasizing the need for comprehensive clinical, neuroimaging, and electrophysiological evaluation. Multimodal treatment approaches focusing on behavioral symptoms and functional support are essential for optimizing patient outcomes.\n\nID: 42331842\nTitle: AOC1 regulates labor initiation through spermidine-induced autophagy of placental trophoblast cells via EIF5A hypusination.\nAbstract: Parturition depends on precise communication between the mother and fetus. While fetal lung signals are known to help initiate labor, the role of the placenta has remained unclear. Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice. Our findings reveal that placental AOC1-spermidine-EIF5A-autophagy axis is essential for parturition timing and offer a potential therapeutic strategy for preterm birth.\n\nID: 42327368\nTitle: Transcriptomic and pathological analysis of the hnRNP network reveals glial involvement in frontotemporal lobar degeneration pathological subtypes.\nAbstract: Frontotemporal dementia is a neurodegenerative disorder with a strong heritable component. Frontotemporal lobar degeneration refers to the pathological changes seen in frontotemporal dementia, characterized by atrophy of the frontal and temporal lobes and the presence of abnormal protein inclusions. In the case of frontotemporal lobar degeneration with hyperphosphorylated TDP-43 positive inclusions (FTLD-TDP), five pathological subtypes (A, B, C, D and E) are observed based on the types and distribution of inclusions found in the brain. In all subtypes, there tends to be a large variability in the number of pathological inclusions observed between cases, with limited correlation to clinical manifestations. TDP-43 is an RNA-binding protein belonging to the heterogeneous nuclear ribonucleoprotein (hnRNP) family, which along with other hnRNPs, modulates multiple aspects of RNA processing. HnRNPs other than TDP-43 have been implicated in several neurological diseases, including Amyotrophic Lateral Sclerosis, FTLD-TDP, frontotemporal lobar degeneration with fused in sarcoma (FTLD-FUS) and Alzheimer's disease. Multiple hnRNPs have been found in pathological inclusions in specific subtypes of FTLD-TDP, suggesting potential roles in the disease process. The role of the hnRNP network in frontotemporal lobar degeneration disease pathogenesis, however, has not yet been investigated. This study aimed to comprehensively evaluate the presence and expression of hnRNP proteins in two pathological subtypes of sporadic FTLD-TDP (A and C) as well as the genetic form FTLD-TDP A C9orf72 using immunohistochemistry and gene expression analysis by single-nuclei RNA-sequencing. We found that there was great variability in the frequency of TDP-43 pathology across and within FTLD-TDP pathological subtypes. Our findings suggest that distinct global transcriptomic profiles may underlie the different pathological subtypes of FTLD-TDP. The most prominent transcriptomic changes were observed in oligodendrocytes and astrocytes, involving multiple hnRNPs across frontotemporal lobar degeneration subtypes compared to controls. Transcriptomic co-expression analysis further revealed that glial clusters were more strongly associated with RNA-processing dysfunction and contributed to disease classification. Together, these findings highlight the involvement of the hnRNP network and glial-specific RNA-processing alterations in FTLD-TDP pathophysiology, offering new insight into the molecular distinctions between pathological subtypes and potential targets for future investigation.\n\nID: 42316301\nTitle: Intrathecal (G4C2)149 delivery in C9orf72-deficient mice yields mild motor dysfunction and ALS/FTD pathological hallmarks.\nAbstract: A repeat expansion in C9ORF72 is the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), yet existing mouse models incompletely engage spinal regions implicated in disease. Here, an adeno-associated virus encoding (G4C2)149 repeats was delivered via neonatal intrathecal injection, achieving widespread CNS expression with robust spinal cord targeting. This approach was applied to mice with graded loss of endogenous C9orf72 to interrogate both gain- and loss-of-function mechanisms. Longitudinal motor, behavioral, and pathological analyses revealed that repeat expression primarily drives mild, progressive muscle weakness, whereas coordination deficits were largely genotype dependent. Subtle gait abnormalities and hyperactivity were also observed. Within spinal motor regions, repeat-expressing mice exhibited dipeptide repeat protein accumulation, reduced NeuN-positive area, fewer motor neurons, glial activation, sparse phosphorylated TDP-43 pathology, and increased cryptic TDP-43 splicing. Cross-domain correlations further linked repeat expression, spinal pathology, and motor dysfunction. Collectively, these findings establish that CNS-wide repeat expression combined with reduced C9orf72 produces a coherent, mild ALS/FTD model.\n\nID: 42308222\nTitle: REPROGRAM: REsilience PROmotion with GeRoprotectors: AssessMent of biological effect: Rationale and protocol for a trial of biological effect.\nAbstract: Ageing is associated with reduced resilience to physiological stressors such as infection and surgery. This reduced resilience is believed to be underpinned by the hallmarks of ageing, the key biological mechanisms driving the aged phenotype. Geroprotectors are drugs that are proposed to slow down the ageing process and promote longevity and healthspan. Despite this, mechanistic studies in healthy older adults are lacking. This trial will test the hypothesis that geroprotectors targeted towards biological mechanisms associated with poor resilience can reverse these pathways within a three-week period. Three geroprotectors with a good safety profile in older adults and evidence of effect on the hallmarks of ageing will be administered to 60 (30 female; 30 male) adults 70\u2009+\u2009. Participants will be randomised to one of three arms (Metformin MR 1500 mg, Fisetin 100 mg or Spermidine 15 mg). Participants will be extensively clinically characterised at baseline. Blood, abdominal adipose tissue and stool samples will be taken at baseline and following the three-week intervention. The primary research question will answer whether a three-week course of Metformin, Spermidine, or Fisetin reduce the number of senescent cells as measured by SA-\u03b2-GAL in adipose biopsies in healthy older volunteers. Additionally, there will be assessment of the effect of the geroprotectors on other hallmarks of ageing, including autophagy, immunosenescence, chronic inflammation, dysregulated mTOR signalling, epigenetic age, DNA damage, dysregulated metabolism, stem cell exhaustion and microbial composition. Ethical approval is in place (24/LO/0549). The main trial report and any sub-studies will be published in high impact peer-reviewed gerontology journals, presented at academic conferences and through a series of public engagement events. Participants enrolled in the study will be informed of the results by a written summary. REPROGRAM was registered with ISRCTN on 10/09/24. ISRCTN47919839.

Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS.\n\nID: 42266427\nTitle: Genetic analysis of limbic-predominant age-related TDP-43 encephalopathy neuropathologic change in a population-based cohort of the oldest old.\nAbstract: Limbic-predominant age-related TDP-43 encephalopathy neuropathologic change is a common proteinopathy in the oldest old that is associated with cognitive decline. Although the genetic basis of limbic-predominant age-related TDP-43 encephalopathy neuropathologic change remains largely unknown, TMEM106B, GRN and APOE loci are frequently implicated. Here, we examined nine previously reported limbic-predominant age-related TDP-43 encephalopathy neuropathologic change risk loci (ARHGEF28, APOE, GRN, KAZN, LHX1, TPCN1, TMEM106B, UNC13C and WWOX) in a population cohort of 262 individuals from the Vantaa 85 + study. We also tested whether Alzheimer's disease polygenic risk score without APOE was associated with limbic-predominant age-related TDP-43 encephalopathy neuropathologic change. Using ordinal logistic regression models, GRN rs5848 (odds ratio = 2.45, 95% confidence interval: 1.71-3.52, adjusted P = 5.75 \u00d7 10-6), APOE \u03b54 dose (odds ratio = 1.73, 95% confidence interval: 1.07-2.80, adjusted P = 0.030) and KAZN rs72643142 (odds ratio = 2.38, 95% confidence interval: 1.38-4.11, adjusted P = 0.0048) were associated with higher limbic-predominant age-related TDP-43 encephalopathy neuropathologic change stage. Additionally, Alzheimer's disease polygenic risk score without APOE was associated with limbic-predominant age-related TDP-43 encephalopathy neuropathologic change after adjusting for age, sex, Alzheimer's disease pathology and APOE \u03b54 dose (odds ratio = 1.36, 95% confidence interval: 1.06-1.75, adjusted P = 0.027). Our findings contribute to the understanding of limbic-predominant age-related TDP-43 encephalopathy neuropathologic change genetics and suggest shared biological processes between limbic-predominant age-related TDP-43 encephalopathy neuropathologic change and Alzheimer's disease.\n\nID: 42248503\nTitle: Overexpression of scavenger receptor class B member 2 leads to different response of ovarian adenocarcinoma cells to chemotherapy.\nAbstract: Scavenger Receptor Class B Member 2 (SCARB2) is an integral lysosomal membrane protein essential for lysosomal integrity and autophagy regulation. The aim of this study was to investigate the functional impact of SCARB2 overexpression on chemotherapy response, reactive oxygen species (ROS) production and proteomic composition of human ovarian adenocarcinoma cells A2780. To induce SCARB2 overexpression, A2780\u202fcells were transfected using a PiggyBac vector system. Two clones with the highest SCARB2 expression (L and V) were selected for further analyses. Differences in chemosensitivity were assessed using the MTS assay. Proteomic analysis was used to identify differentially expressed proteins and enriched pathways. We also performed flow cytometry to investigate changes in ROS production and lysosomal activity. Lysosomal distribution was assessed using LAMP1 immunofluorescence staining followed by confocal microscopy, and total cholesterol levels were determined using an enzymatic colorimetric assay. Both clones showed increased sensitivity to cisplatin compared to the control group. In contrast, clone V showed resistance to doxorubicin and no significant differences were observed for gemcitabine, except for a transient sensitizing effect when low concentrations used. Elevated ROS levels were detected in untreated clones, and after doxorubicin exposition. Proteomic analysis showed significant changes in lysosome-associated proteins, with consistent enrichment of the lysosomal pathway across all experimental comparisons. Immunofluorescence analysis of LAMP1 and LysoTracker staining demonstrated altered lysosomal distribution and activity in SCARB2-overexpressing clones. In addition, both SCARB2-overexpressing clones exhibited significantly reduced total cholesterol levels compared with control cells. This study broadens our understanding of SCARB2 in ovarian cancer. SCARB2 overexpression induces extensive lysosomal reprogramming in A2780 ovarian cancer cells and modulates chemotherapy response.\n\nID: 42225652\nTitle: Insights into the therapeutic strategies for aging and aging-associated diseases.\nAbstract: Aging is a complex biological process characterized by progressive functional decline, driving the incidence of age-related diseases such as neurodegeneration, metabolic disorders, and cardiovascular diseases. Therapeutic strategies targeting aging hallmarks can delay aging and mitigate disease risk. Emerging interventions focus on modulating core aging mechanisms, including cellular senescence, metabolic dysfunction, epigenetic alterations, and mitochondrial impairment, etc. Recent advances have focused on three strategies: senolytics (eliminating senescent cells, e.g., dasatinib + quercetin), senomorphics (inhibiting the senescence-associated secretory phenotype, e.g., rapamycin), and senoreversion (rejuvenating senescent cells via epigenetic reprogramming). Additionally, metabolic interventions such as caloric restriction mimetics (e.g., spermidine, \u03b1-ketoglutarate, ergothioneine) enhance mitochondrial function, activate autophagy, and reprogram energy metabolism, demonstrating lifespan extension and healthspan improvement in preclinical models. Collectively, these approaches hold promise for delaying aging and alleviating age-related pathologies, facilitating the transition to precision longevity medicine. Concurrently, artificial intelligence (AI) accelerates discovery by integrating multiomics data, predicting candidate compounds, identifying biomarkers, and enabling personalized interventions. Despite advancements, challenges remain in target specificity, off-target effects, and clinical translation. The convergence of AI, multitarget strategies, and precision medicine signals a transformative era in extending healthspan and combating aging-associated diseases. This review systematically summarizes current breakthroughs, clinical landscapes, and future directions in aging therapeutics, underscoring interdisciplinary strategies to redefine healthy aging.\n\nID: 42222188\nTitle: Dietary pyrroloquinoline quinone and spermidine in healthy longevity: targeting the hallmarks of aging.\nAbstract: Aging is a multifaceted biological process driven by interconnected cellular and molecular hallmarks. As geroscience increasingly prioritizes healthspan over lifespan, nutritional interventions targeting multiple aging mechanisms have gained attention as accessible strategies to mitigate age-related functional decline. This mini review synthesizes recent evidence on how the bioactivities of two food-derived geroprotective compounds, pyrroloquinoline quinone (PQQ) and spermidine (SPD), intersect with the hallmarks of aging and their distinct and overlapping roles in maintaining cellular homeostasis. PQQ primarily functions as a mitochondrial and redox regulator, enhancing mitochondrial biogenesis and bioenergetic capacity through the AMP-activated protein kinase (AMPK) and sirtuin1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator 1-alpha pathways. In contrast, SPD acts as a key regulator of cellular quality control by inducing macroautophagy and preserving proteostasis, largely through modulation of histone and autophagy-related protein acetylation. These complementary mechanisms converge on several key hallmarks of aging, including genomic instability, deregulated nutrient sensing, mitochondrial dysfunction, and chronic inflammation. The anti-aging mechanisms of PQQ and SPD originate from distinct upstream biochemical processes but converge on shared signaling hubs, including the AMPK/SIRT1 axis and autophagy-related networks. This convergence suggests a coordinated network-level complementarity that may offer a more robust intervention against age-related decline than targeting independent pathways alone.\n\nID: 42605115\nTitle: Surface-Engineered Carbon Dots for Monitoring of Lysosomal Viscosity and Organelle Dysfunction.\nAbstract: The development of robust, photostable nanoprobes for precise organelle targeting remains a cornerstone in chemosensing and advanced bioimaging. Alterations in the lysosomal microenvironment serve as an indicator of organelle health and disease progression. Herein, a sustainable synthetic strategy is presented for benzothiazole-modified carbon dots (LysoDots), engineered for specific lysosome localization and viscosity monitoring. LysoDots display a viscosity-dependent fluorescence enhancement in glycerol-water systems while remaining insensitive to physiological pH and temperature variations. This turn-on response allows for the high-fidelity tracking of lysosomal microviscosity changes induced by exogenous stimuli, such as nystatin, and endogenous processes like rapamycin-induced autophagy. Confocal imaging demonstrates a remarkable colocalization of LysoDots with the commercial lysosome marker, LysoTracker Green (LTG), showing a Pearson's correlation coefficient of 0.92 in CAL-33 oral carcinoma cells, with the red emission effectively differentiating lysosomal viscosity profiles between cancerous and non-cancerous cells. Furthermore, the LysoDots were successfully employed in a neuronal model, SH-SY5Y cells, where the probe effectively tracked glutamate-induced lysosomal dysfunction, mimicking the pathology of lysosomal storage disorders, along with the viscosity restoration mediated by trehalose. These findings highlight the potential of LysoDots as a biocompatible, photostable, multi-functional nanomaterial for long-term monitoring of lysosomal dynamics and cellular homeostasis.\n\nID: 42599231\nTitle: [Yeast as a Biochemical Model for Diseases Associated with Impaired Intracellular Proteolytic Systems].\nAbstract: The degradation of intracellular proteins is a fundamental biological process necessary for maintaining cellular homeostasis, controlling the cell cycle, regulating signal transduction, and preventing the accumulation of toxic protein aggregates. Disorders of the proteolytic systems are implicated in the pathogenesis of numerous human diseases, including neurodegenerative diseases, lysosomal storage disorders, metabolic disorders, and certain types of cancer. The development of rudimentary and cost-effective models of these diseases for the purpose of evaluating novel pharmaceutical agents and elucidating the molecular mechanisms underlying disease pathogenesis constitutes a pivotal medical and biological undertaking. The proteolytic apparatus of the yeast species Saccharomyces cerevisiae has become a biochemical model organism of significant importance. This is due to its well-studied nature, low cost, ease of genetic manipulation, and evolutionary conservatism. The mechanisms of proteolytic system dysfunction can be studied in this organism. Furthermore, therapeutic approaches aimed at correcting these dysfunctional mechanisms can be sought.\n\nID: 42580143\nTitle: Tripartite motif 16 mitigates endotoxemia-induced cardiac dysfunction via the Cav-1/Src/YAP signaling axis in mice.\nAbstract: Septic cardiomyopathy (SIC) is a life-threatening complication of sepsis with limited therapeutic options. Tripartite Motif 16 (TRIM16), an E3 ubiquitin ligase, is implicated in cellular stress responses, but its role in SIC remains unknown. In neonatal rat cardiomyocytes (NRCMs) and a murine cecal ligation and puncture (CLP)-induced sepsis model, we manipulated TRIM16 expression using small interfering RNA (siRNA), plasmids, or adeno-associated virus (AAV9)-mediated gene delivery. Cardiac function, injury markers, oxidative stress, inflammation, apoptosis, calcium handling, lysosomal function, and autophagy were assessed. Mechanistic studies focused on caveolin-1 (Cav-1) ubiquitination, non-receptor tyrosine kinase (Src)/yes-associated protein (YAP) activation, and the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway. TRIM16 expression was markedly upregulated in cardiomyocytes under septic conditions. Knockdown of TRIM16 exacerbated lipopolysaccharide (LPS)-induced cardiomyocyte injury, amplifying oxidative stress, inflammation, apoptosis, calcium dysregulation, lysosomal dysfunction, and impaired autophagy. In contrast, TRIM16 overexpression significantly attenuated cardiac dysfunction and injury in CLP-challenged mice. Mechanistically, TRIM16 directly promoted ubiquitination and degradation of Cav-1, which relieved Cav-1-mediated inhibition of Src kinase (increased p-Src Y416 and decreased p-Src Y527). This led to YAP phosphorylation at Y357, nuclear translocation, and subsequent activation of the Nrf2/HO-1 antioxidant pathway, thereby mitigating oxidative stress and restoring redox homeostasis. This study identifies a previously unrecognized protective role for TRIM16 in SIC via the novel Cav-1/Src/YAP/Nrf2 signaling axis. By enhancing TRIM16 activity, oxidative stress and cardiac dysfunction are mitigated, positioning TRIM16 as a promising therapeutic target for SIC.\n\nID: 42577502\nTitle: Research progress on the \u03b1-synuclein-lysosome axis in Parkinson's disease: molecular mechanisms of protein aggregation, autophagy dysfunction, and therapeutic targeting.\nAbstract: Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder worldwide, characterized pathologically by the loss of dopaminergic neurons in the substantia nigra and the formation of Lewy bodies, which predominantly consist of misfolded \u03b1-synuclein (\u03b1-Syn) aggregates. Recent advances have highlighted the critical role of the interplay between \u03b1-Syn and lysosomal function, termed the \u03b1-Syn-lysosome axis, as a central mechanism underlying PD pathogenesis. This review systematically summarizes the molecular mechanisms driving \u03b1-Syn aggregation and the lysosomal dysfunction contributing to impaired autophagy-lysosome pathway (ALP) activity. We further discuss emerging therapeutic strategies targeting this axis to restore lysosomal function and mitigate \u03b1-Syn toxicity. By integrating the latest findings from molecular biology, cell biology, and preclinical studies, this article aims to elucidate the complex regulatory network of the \u03b1-Syn-lysosome axis and provide a theoretical foundation for the development of novel therapeutic interventions for PD.\n\nID: 42576068\nTitle: Established and emerging roles of lysosomal dysfunction in cardiac aging.\nAbstract: Cardiac aging is a central biological process underlying most cardiovascular diseases. Lysosomes, once regarded as terminal degradative compartments, are now recognized as dynamic metabolic and signaling hubs whose dysfunction has profound consequences for the aging heart. Human lysosomal storage disorders provide compelling evidence that isolated lysosomal defects are sufficient to cause early cardiomyopathy, underscoring the myocardium's exceptional dependence on sustained lysosomal competence. In physiological aging, impaired autophagy is the most apparent manifestation of lysosomal decline but represents only one facet of a broader network regulating nutrient sensing, ion and lipid homeostasis, receptor trafficking, exocytosis/secretion and inter-organelle communication. Here, we review established and emerging lysosome-dependent mechanisms across the hallmarks of cardiac aging, highlighting lysosomes as potential upstream drivers of this process. We discuss key knowledge gaps and therapeutic strategies aimed at restoring lysosomal function, positioning lysosomes as central and actionable targets for preserving cardiac resilience with age.\n\nID: 42555719\nTitle: Renoprotective effects of tubular glucagon receptor activation mediated by V-ATPase.\nAbstract: Recent clinical trials have shown that dual GLP-1R/GCGR agonists, including mazdutide and cotadutide, provide kidney benefits in patients with type 2 diabetes and CKD, suggesting a potential contribution of GCGR activation to these renal effects. However, whether GCGR directly confers renoprotection and the underlying mechanisms remain unclear. Here, using tubule-specific GCGR loss- and gain-of-function mouse models and human kidney samples, we show that tubular GCGR signaling exerts an important renoprotective role in DKD. Tubular GCGR expression is reduced in humans and mice with DKD and correlates with worse kidney function and increased renal injury. Genetic ablation of tubular GCGR markedly exacerbates DKD and induces pronounced phospholipid accumulation within enlarged lysosomes. Mechanistically, GCGR loss disrupts its association with the V-ATPase V1A subunit ATP6V1A, compromises V1-V0 assembly, and thereby impairs lysosomal acidification. This defect leads to impaired phospholipid hydrolysis and protease maturation, blockade of autophagic flux, and ultimately tubular cell injury. In vivo, ATP6V1A overexpression markedly reverses GCGR deficiency-induced lysosomal dysfunction and DKD progression. Consistently, re-expression of tubular GCGR via AAV9 restores lysosomal function, reduces phospholipid accumulation, and mitigates renal injury in DKD. Together, these findings provide genetic evidence for the renoprotective role of tubular GCGR in DKD, delineate a kidney-intrinsic GCGR-ATP6V1A-lysosome axis that protects tubular integrity, and extend prior GCGR-in-kidney observations into a more concrete GCGR-lysosome mechanism.\n\nID: 42553702\nTitle: Distinct brain extracellular vesicle microRNA profiles differ in frontotemporal dementia and Alzheimer's disease.\nAbstract: Dementia is a syndrome caused by various diseases including Alzheimer's disease (AD) and frontotemporal dementia (FTD) with an estimated global prevalence of 60 million individuals. Recently, therapeutic development in the dementia field has accelerated, with the introduction of monoclonal antibody therapeutics such as Lecanemab and Donanemab. However, AD and FTD patients are still either diagnosed too late to benefit from available therapies or are misdiagnosed due to the clinical overlap between dementia subgroups making therapeutic intervention challenging. This highlights a real need to improve early diagnostic tools of neurodegenerative disease (ND) biomarkers. A potential source of such biomarkers come from small extracellular vesicles (sEVs), groups of cell-derived, lipid-bound assemblies with the capability to cross the blood-brain barrier (BBB) and known to carry pathogenic proteins associated with AD and FTD. A known cargo of sEVs is microRNA (miRNA), regulatory molecules that post-transcriptionally silence gene expression including transcripts of autophagic systems, processes which dysfunction in dementia-causing diseases leading to toxic aggregate build-up, causing neurodegeneration. The targeting of functional machineries in macroautophagy (MA) and chaperone-mediated autophagy (CMA) by different miRNA may vary between AD and FTD mutations, leading to potential biomarkers of disease being highlighted. Through isolating sEVs from the frontal cortex of post-mortem brain tissue of AD, FTD-MAPT, FTD-C9orf72, FTD-GRN and no-disease control patients (Manchester Brain Bank), miRNA cargoes were analysed and compared using real-time quantitative PCR (RT-qPCR). Seven autophagy-associated miRNA candidates (MA: miR-124-3p, miR-30a-5p, miR-128-3p; and CMA: miR-224-5p, miR-373-5p, miR-106a-3p and miR-26b-5p) were tested to identify dementia sub-group variations, used alongside small RNA-sequencing to explore broader miRNA variation within sEV populations. Of the miRNA tested miR-224-5p (P = 1.76 \u00d7 10-5) and miR-106a-3p (P = 0.033) showed significant group differences, and further significant pairwise comparison differences [miR-224-5p: AD fold change (FC) = 4.29, MAPT FC = 7.62; miR-106a-5p: AD FC = 5.59] when compared with no disease controls and other dementia subgroups, potentially showing initial diagnostic and differentiating potential. Small RNA-sequencing results revealed 8 AD, 2 FTD-GRN, 52 FTD-MAPT and 12 FTD-C9orf72 differentially expressed sEV-miRNAs when compared with no disease controls. Further direct comparisons between AD versus FTD mutation-derived sEV cargoes, and even FTD mutation versus FTD mutation-derived sEV cargoes, identified additional miRNA with differentiating capabilities. These findings demonstrate sEV-derived miRNA signatures vary across dementia sub-types and suggest potential roles of sEV cargoes in both disease diagnostics and identifying drivers of ND, such as autophagic impairments and signalling pathways.\n\nID: 42553289\nTitle: Rapamycin-nanoliposomes target the mTORC1-mediated autophagy-lysosomal and NLRP3/Caspase-1 pathways to inhibit nucleus pulposus cell senescence in intervertebral discs.\nAbstract: Nucleus pulposus (NP) cell quiescence maintains intervertebral disc homeostasis, while mTORC1 regulates autophagy-lysosomal function and inflammatory secretion to preserve quiescence-rapamycin specifically targets mTORC1. Herein, we fabricated rapamycin-nanoliposomes (rapa-lipos) via ultrasonic dispersion, thin-film dispersion, and filtration to improve rapamycin bioavailability, investigating their role in inhibiting the senescence phenotype of NP cells through \u03b2-gal staining, lysosomal staining, transmission electron microscopy, ELISA, and cell cycle inhibitors. The mechanistic effects of rapa-lipos on mTORC1, NLRP3/Caspase-1 pathway (NCP) and autophagy-lysosomal pathway (ALP) were also analyzed by western blotting, immunofluorescence (IF), Si-RNA (raptor), and PCR. In vivo, rapa-lipos were injected into rat intervertebral disc with IL-1\u03b2-induced degeneration, assessed via HE staining, x-ray, MRI, and IF. Rapa-lipos exhibited high encapsulation efficiency, favorable drug loading, uniform particle size, and controlled release, suppressing NP cell senescence-related phenotypes (morphological changes, elevated IL-1\u03b2/TNF-\u03b1 secretion, increased \u03b2-gal activity, lysosomal dysfunction, upregulated P21/P16 and reduced P27 expression). Mechanistically, rapa-lipos targeted-inhibited mTORC1, then blocked NCP and activated ALP to maintain NP cell quiescence. In vivo, x-ray, MRI and histological evaluation confirmed rapa-lipos mitigated intervertebral disc degeneration.

These symptoms are heterogeneous and may reflect syndromal MDD, psychological and functional burden, fatigue, apathy, pseudobulbar affect, frontotemporal involvement, sleep or respiratory disturbance, medication effects, or shared affective vulnerability. A proposed pruning-continuum model suggests both disorders may share vulnerability in microglia-mediated synaptic pruning, with ALS amplified by autophagy and protein-quality-control failure and MDD by RNA-processing, stress, and immune dysregulation. We performed an exploratory secondary transcriptome-wide association study (TWAS)/pathway-integration analysis to test whether predefined nicotinamide mononucleotide (NMN)-nominated pathways map onto this vulnerability. We integrated precomputed S-PrediXcan outputs for MDD and ALS across available brain-relevant tissues. Ten Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were predefined from a prior re-analysis of NMN-associated transcriptional programs in aged mouse metabolic tissues. Mouse-derived candidates were represented by human ortholog symbols before the human TWAS screen. The analysis tested nominated pathways rather than the 35-gene NMN-robust list as a standalone set. Cross-tissue screening used Stouffer Z aggregation, tissue-level Wilcoxon testing, competitive permutation testing, percentile bootstrap intervals, pairwise disease statistics, Levene variance tests, concordance measures, and leave-one-out sensitivity analysis. No analysis was treated as confirmatory or evidence of causal mediation. MDD showed the strongest Stouffer-based exploratory signal in the synaptic vesicle cycle pathway, with a meta-across-tissue Stouffer Z of 3.41 and a wide bootstrap 95% confidence interval of -0.46 to 7.40. This signal did not survive competitive permutation testing (p = 0.1222) or Wilcoxon testing (p = 0.1926). The strongest tissue-level result occurred in the amygdala (Z = 4.057; nominal Wilcoxon p = 0.0093), although tissue-level permutation testing was not performed in the multi-gene-set run. ALS showed no significant meta-across-tissue enrichment among the 10 nominated pathways but displayed candidate gene-level signals in autophagy, endosomal, and vesicle-related genes, including TBK1 and C9orf72. Exploratory Levene tests indicated variance heterogeneity in the regulation of the actin cytoskeleton, endocytosis, and neuroactive ligand-receptor interaction; the actin cytoskeleton and endocytosis remained significant in pooled global false discovery rate (FDR) analysis. Fourteen genes were influential in at least two focus pathways, including EGF, KNG1, FGF8, RAC1, PAK1, PAK2, RAF1, MAPK1, and FGFR1. These findings are hypothesis-generating. MDD and ALS may stress overlapping cellular logistics processes while engaging largely different genes. MDD showed the strongest exploratory pathway-level signal in synaptic vesicle biology, whereas ALS showed candidate gene-level coherence in autophagy and endosomal processes without significant meta-pathway enrichment. NMN/NAD+ repletion is not established as a treatment for MDD, ALS, or their comorbidity. These findings generate hypotheses about NAD+-linked cellular stress pathways for future preclinical and clinical studies.\n\nID: 42529163\nTitle: The endo-lysosomal-lipid axis: bidirectional interactions between membrane trafficking dysfunction and lipid metabolic disorders.\nAbstract: The endo-lysosomal system is a central regulator of intracellular trafficking, cargo degradation, and metabolic homeostasis. Its dynamic function is closely intertwined with lipid metabolism, forming an integrated regulatory network termed the endo-lysosomal-lipid axis. Disruption of this axis can impair endosomal maturation, lysosomal acidification, autophagic degradation, and lysosome-centered signaling pathways, resulting in defective cellular clearance and chronic inflammatory responses. Conversely, dysfunction of the endo-lysosomal system disrupts cholesterol trafficking, lipid redistribution, and macromolecular degradation, ultimately promoting secondary lipid accumulation and metabolic imbalance. In this review, we summarize the reciprocal interactions between lipid metabolism and endo-lysosomal function, with particular emphasis on membrane trafficking, lysosomal homeostasis, autophagy, membrane contact sites, and multicellular lipid clearance networks. We further discuss how these interconnected processes contribute to disease progression and highlight emerging therapeutic strategies aimed at restoring lysosomal function and lipid homeostasis. Understanding the dynamic regulation of the endo-lysosomal-lipid axis may provide new mechanistic insights into metabolic and neurodegenerative disorders and identify novel therapeutic opportunities.\n\nID: 42511762\nTitle: Autophagy-Lysosomal Dysfunction as a Converging Mechanism of Cardiomyopathy in Lysosomal Storage Disorders: From Pathobiology to Targeted Therapy.\nAbstract: Cardiac disease is a leading cause of morbidity and early death across several lysosomal storage disorders (LSDs); however, the cardiomyopathies of Fabry, Pompe, and Danon disease are still largely treated as separate, substrate-specific disorders. We argue that they are better understood as variations on a single theme: the breakdown of the autophagy-lysosome system within cardiomyocytes. In the healthy heart, this system clears damaged proteins and organelles and is regulated by mTORC1 and the master regulator TFEB. Once lysosomal degradation or autophagosome-lysosome fusion fails, undegraded substrates and defective mitochondria accumulate, driving hypertrophy, interstitial fibrosis, and conduction disease. Danon disease, resulting from the loss of LAMP2, is the clearest example of a primary defect in autophagic flux, whereas the glycogen storage of Pompe disease and the globotriaosylceramide accumulation of Fabry disease impair flux through different upstream mechanisms that converge on the same downstream injury. The same framework extends to other storage disorders with cardiac involvement, such as mucopolysaccharidosis (MPS). We trace this shared pathobiology from molecule to bedside, examine biomarkers that reflect lysosomal and autophagic dysfunction rather than storage alone, and re-examine treatment in that light: why enzyme replacement therapy corrects substrate accumulation but leaves much of the autophagic and mitochondrial damage unresolved, and why gene therapy-particularly AAV9-LAMP2B for Danon disease-together with autophagy- and TFEB-directed strategies may help close that gap. Viewing these disorders through a single mechanistic lens reshapes how we monitor them and where future therapies should be directed.\n\nID: 42510554\nTitle: HGA-Induced Oxidative Stress Impairs Autophagy via Lysosomal Dysfunction in Alkaptonuria.\nAbstract: Alkaptonuria (AKU) is a rare metabolic disorder caused by homogentisate 1,2-dioxygenase deficiency, leading to systemic accumulation of homogentisic acid (HGA) and progressive tissue degeneration characterized by dark urine, ochronosis, and severe osteoarthropathy. Chronic exposure to HGA promotes oxidative stress, chondroptosis, secondary amyloidosis, and impaired autophagy, an essential process for maintaining chondrocyte homeostasis. This study investigated the mechanisms potentially involved in autophagy dysregulation in AKU using the human C20/A4 chondrocyte line treated with 0.1 mM HGA, an established in vitro model of the disease. The findings were then verified using chondrocyte cells and cartilage tissue obtained from AKU biopsies. HGA treatment induced a time-dependent increase in oxidative stress, evidenced by elevated ROS levels, 4-HNE accumulation, and overproduction of mitochondrial superoxide. Autophagy assessment showed an early increase in autophagy-related markers, with increased LC3 and p62 expression and enhanced lysosomal biogenesis (LAMP1). However, prolonged HGA exposure was associated with reduced LC3/LAMP1 colocalization, persistent p62 accumulation, altered acidic compartment staining, and accumulation of autophagy-related structures, supporting a dysregulation of the autophagy-lysosomal pathway. Live-cell imaging further supported a transition from functional autophagy to lysosomal failure under chronic oxidative stress. Overall, this study suggests that prolonged HGA exposure disrupts the interplay between oxidative stress and autophagic flux. The progressive collapse of these adaptive mechanisms may contribute to chondrocyte degeneration and to the pathogenesis of cartilage damage in AKU.\n\nID: 42494065\nTitle: IL17A disrupts autophagy-lysosomal function and lysosome reformation through the GSK3B-TFE3 signaling pathway in Huntington disease.\nAbstract: Huntington disease (HD) is a progressive neurodegenerative disease caused by an expanded CAG repeat in the HTT (huntingtin) gene, leading to the accumulation of mutant HTT (mHTT). IL17A (interleukin 17A), a proinflammatory cytokine primarily secreted by Th17 and \u03b3\u03b4 T cells, has been implicated in immune-mediated neurodegeneration. However, the role of IL17A in the pathogenesis of HD remains poorly understood. Here, we identify IL17A as a critical pathogenic factor in HD that promotes neuroinflammation, mHTT aggregation, and autophagy-lysosomal dysfunction. IL17A disrupts autophagic flux by downregulating CTSB and CTSD, inducing SQSTM1/p62 and MAP1LC3B-II/LC3-II accumulation, and impairing lysosomal reformation. Mechanistically, IL17A suppresses lysosomal biogenesis by inhibiting the nuclear translocation of TFE3. This regulation occurs via a novel GSK3B/GSK-3\u03b2-TFE3 signaling pathway. Therapeutic neutralization of IL17A with a monoclonal antibody (IL17A mAb) ameliorates disease phenotypes in R6/2 HD mice, improving motor performance, extending survival, and reducing gliosis. IL17A mAb also attenuates mHTT aggregation and enhances neuroprotective signaling, as evidenced by increased expression of DLG4/PSD-95, phosphorylated CREB1, and BDNF. Moreover, IL17A mAb restores autophagy-lysosomal function by facilitating the clearance of protein aggregates and upregulating lysosomal enzymes and biogenesis markers, including CTSB, CTSD, PIP5K1A, and LAMP2. These findings establish IL17A as a key modulator of HD pathophysiology and highlight IL17A inhibition as a promising therapeutic strategy for targeting autophagy-lysosomal dysfunction in HD.\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: 42467639\nTitle: N-acetyl-L-leucine normalizes Transcription Factor EB activity by stereospecific bidirectional modulation in a HeLa cell model of Niemann-Pick disease type C.\nAbstract: Levacetylleucine (Aqneursa\u2122), an acetylated derivative and pro-drug of L-leucine, is the only FDA-approved monotherapy for Niemann-Pick disease type C (NPC). Its acetyl group enables transport via monocarboxylate transporters, supporting blood-brain barrier penetration and efficient cellular uptake. Inside cells, levacetylleucine is metabolised by acylases, generating elevated levels of L-leucine that enhance mitochondrial bioenergetics and is thought to ameliorate lysosomal dysfunction indirectly. Here, we describe a direct effect of levacetylleucine on lysosomal regulation through modulation of TFEB, the master transcription factor for lysosomal and autophagy genes. Levacetylleucine rapidly alters TFEB translocation between the cytoplasm and the nucleus in a biphasic, homeostasis-restoring manner. In wild-type HeLa cells, levacetylleucine promotes TFEB activation and nuclear localisation. However, in NPC1 disease models, where we show that TFEB is over-activated and enriched in the nucleus due to lysosomal stress, levacetylleucine reduces nuclear TFEB and restores a more normal cytoplasmic-to-nuclear balance. These effects occur at clinically relevant concentrations associated with lysosomal storage reduction. The effects of the drug are stereospecific: while the L-enantiomer is active, the D-enantiomer and racemate show no effect, revealing the antagonistic properties of the D-enantiomer. This bidirectional normalisation of TFEB activity highlights a direct mechanism through which levacetylleucine modulates lysosomal and autophagic pathways in the HeLa cell model, giving mechanistic insight into its therapeutic potential in NPC, and also across diverse neurological and neurodevelopmental disorders.\n\nID: 42464356\nTitle: Transplantation of human iPSC-derived microglia ameliorates neuropathology and circuit dysfunction in progranulin-deficient mice.\nAbstract: Frontotemporal dementia (FTD) is a major cause of early-onset neurodegeneration characterized by progressive behavioral, emotional, and cognitive decline. Progranulin haploinsufficiency, a leading genetic cause of familial FTD, disrupts lysosomal function, lipid metabolism, autophagy, and neuroimmune signaling across multiple cell types. Increasing evidence indicates that microglia are particularly sensitive to progranulin loss, exhibiting elevated complement activation that contributes to TDP-43 proteinopathy and neuronal dysfunction. Here, we investigate the biological role of restoring progranulin exclusively within microglia by transplanting human induced pluripotent stem cell-derived microglial progenitors into progranulin (Grn)-deficient mice. We find that engraftment of wild-type, but not Grn-deficient, human microglia restore brain-wide progranulin levels, normalize microglial transcriptional states, and ameliorate pathological, functional, and behavioral phenotypes associated with progranulin loss. Because human microglia are the only source of progranulin in this system, these findings demonstrate that microglial progranulin is sufficient to restore key aspects of cellular, circuit, and behavioral homeostasis in a progranulin-deficient FTD model. More broadly, this work highlights a central, microglia-intrinsic role for progranulin in maintaining brain function and provides a framework for dissecting microglia-specific mechanisms across FTD and related neurodegenerative disorders.\n\nID: 42458574\nTitle: V-ATPase-targeted siRNA library screening reveals ATP6V1A negatively regulates UVB-induced keratinocyte senescence.\nAbstract: Photoaging is a form of premature skin aging mainly induced by long-term exposure to ultraviolet exposure. Lysosomes are key organelles responsible for the degradation and recycling of intracellular components and are essential for maintaining metabolic and nutrient homeostasis. Although lysosomal dysfunction is closely associated with cellular aging, the role of V-ATPase in regulating lysosomal function during photoaging remains incompletely understood. By screening a V-ATPase-targeted siRNA library and validating the results using publicly available single-cell transcriptomic datasets, we identified ATP6V1A as a key regulator of UVB-induced cellular senescence. Furthermore, ATP6V1A knockdown exacerbated the UVB-induced cellular senescence and impaired lysosomal acidification and membrane integrity, whereas ATP6V1A overexpression effectively alleviated keratinocyte senescence, lysosomal dysfunction and autophagy inhibition. Moreover, treatment with the V-ATPase inhibitor BafA1 aggregated cellular senescence phenotype and autophagy inhibition and this phenomenon partially reversed by ATP6V1A overexpression. Collectively, ATP6V1A promotes autophagy by regulating lysosomal function, thereby relieving UVB-induced cellular senescence.\n\nID: 42456960\nTitle: Di(2-ethylhexyl) phthalate exposure aggravates amyloid-beta-induced toxicity in transgenic AD Caenorhabditis elegans via exacerbating lysosomal dysfunction and oxidative stress.\nAbstract: Di(2-ethylhexyl) phthalate (DEHP) is a widely used plasticizer and environmental contaminant. DEHP exposure has been linked to neurotoxicity in Alzheimer's disease (AD), yet the underlying mechanisms remain unclear. Here, we found that DEHP exacerbated amyloid-beta (A\u03b2)-induced toxicity in transgenic AD Caenorhabditis elegans (C. elegans) models. Meanwhile, the accumulation of SQST-1 was increased, indicating that the autophagic flux was impaired. Consistently, A\u03b2 deposition was elevated in DEHP-treated AD C. elegans. Further investigation revealed that DEHP treatment resulted in lysosomal dysfunction accompanied by a significant decrease in lysosome number. The expression of hlh-30, a key transcription factor involved in lysosomal biogenesis, as well as its downstream lysosome-related genes, including cup-5, vha-17, and lmp-1, was reduced by DEHP. Moreover, hlh-30 RNAi abolished the exacerbation of A\u03b2 toxicity induced by DEHP, indicating that the modulation of hlh-30 was a critical mechanism underlying the effects of DEHP. Additionally, DEHP aggravated oxidative stress in AD C. elegans, while the antioxidant N-acetylcysteine alleviated lysosomal impairment and reduced A\u03b2 deposition, suggesting that the elevated oxidative stress was a key contributor to DEHP-induced lysosomal dysfunction and autophagy impairment. These findings highlight lysosomal impairment as a key mechanism contributing to DEHP-exacerbated toxicity in AD models, and suggest the possibility of using antioxidants to prevent DEHP-induced toxicity.\n\nID: 42456394\nTitle: Defective lysosomal acidification promotes chondrocyte senescence and autophagic flux stagnation in geriatric osteoarthritis.\nAbstract: Geriatric osteoarthritis (G-OA) represents a senescence and metabolism-driven pathobiological phenotype, closely associated with ageing. Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA.\n\nID: 42454472\nTitle: Hydroxychloroquine and the cardiovascular system: lights and shadows.\nAbstract: To review the dual impact of hydroxychloroquine (HCQ) on the cardiovascular system, focusing on both its cardioprotective effects and potential cardiotoxicity in patients with autoimmune diseases. A structured narrative review of the literature was conducted using PubMed/MEDLINE up to March 2025. Relevant studies including clinical trials, observational studies, mechanistic research, and reviews were selected to summarise the molecular mechanisms and cardiovascular effects of HCQ. HCQ exerts multiple beneficial cardiovascular effects through anti-inflammatory, antithrombotic, metabolic, and endothelial-protective mechanisms. It reduces cytokine production, oxidative stress, platelet activation, and improves lipid and glucose profiles, contributing to decreased cardiovascular risk in patients with systemic autoimmune diseases. However, HCQ may also induce cardiotoxic effects, particularly with long-term use or high cumulative doses. These include QT interval prolongation, conduction abnormalities, and a rare but severe form of cardiomyopathy related to lysosomal dysfunction and impaired autophagy. The risk is higher in patients with advanced age, renal dysfunction, pre-existing heart disease, or concomitant use of QT-prolonging drugs. HCQ has a complex and context-dependent cardiovascular profile. While generally cardioprotective at standard doses, it may lead to rare but serious cardiac adverse effects in highrisk patients. A risk-adapted monitoring strategy is essential to optimise its benefit-risk balance in clinical practice.\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: 42427771\nTitle: The NORAD-pumilio regulatory axis links lncRNA dysregulation to tau propagation-associated phenotypes.\nAbstract: Long non-coding RNAs (lncRNAs) are increasingly implicated in neurodegenerative disease, yet their roles in tauopathy remain poorly understood. Here, we defined the lncRNA landscape across iPSC-derived neurons, astrocytes, and microglia harboring the frontotemporal dementia-associated MAPT IVS10+16 mutation and investigated how lncRNA dysregulation interfaces with tau pathology. Transcriptomic analyses revealed extensive cell-type specific lncRNA expression changes, with neurons exhibiting the greatest degree of mutation-associated remodeling. Comparative analyses with MAPT IVS10+16 patient brain tissue identified NORAD and MIR22HG as lncRNAs significantly dysregulated across all three cell types and human brains. NORAD was also altered in Alzheimer's disease and Parkinson's disease brains, suggesting a broader role in neurodegenerative disease. Mechanistically, NORAD-associated protein networks converged on pathways related to RNA regulation, cytoskeletal organization, proteostasis, and tau interaction networks. Given the established role of NORAD in regulating PUM1 and PUM2 RNA-binding (pumilio) proteins, we examined the NORAD-pumilio axis and identified enrichment of pumilio-associated pathways linked to autophagy, endocytosis, proteostasis, and cytoskeletal regulation. NORAD depletion reduced tau seeding and uptake, whereas functional depletion of PUM1 or PUM2 increased both processes, supporting an antagonistic relationship between NORAD and pumilio signaling in modulation of tau aggregation. Together, these findings identify widespread lncRNA dysregulation across neural cell types in the setting of a MAPT mutation and nominate the NORAD-pumilio axis as a regulatory pathway linking RNA homeostasis and tau propagation biology.\n\nID: 42415176\nTitle: Zinc-mediated lysosomal activation by 1H10 enhances autophagy and attenuates tau pathology in Alzheimer's disease models.\nAbstract: Impaired autophagic flux and lysosomal dysfunction contribute critically to the accumulation of pathological protein aggregates in Alzheimer's disease (AD). Emerging evidence suggests that intracellular zinc dynamics regulate lysosomal function by modulating processes such as acidification and lysosomal biogenesis. We previously identified 1H10 as an AMP-activated protein kinase (AMPK) inhibitor and subsequently demonstrated its zinc-binding capacity and ability to regulate intracellular zinc homeostasis. Building on our prior findings that intra-lysosomal zinc promotes acidification and activates transcription factor EB (TFEB), we investigated whether 1H10 enhances lysosomal function through zinc mobilization in neurons, thereby improving autophagy and reducing pathological protein accumulation. In primary cortical neurons, 1H10 increased lysosomal abundance and enhanced lysosomal degradative capacity in a zinc-dependent manner, as demonstrated by increased cathepsin B activity and DQ-BSA degradation. It alleviated lysosomal dysfunction induced by v-ATPase inhibition and promoted autophagic flux, leading to reduced accumulation of amyloid-\u03b2 (A\u03b2) and tau in neuronal models. In 5XFAD mice, 1H10 treatment showed trends toward improved spatial learning in the Morris water maze, reduced tau phosphorylation at Thr205 and Ser214, normalized LC3-II levels, and restored autophagic-lysosomal homeostasis, without significant changes in extracellular amyloid plaque burden. These findings indicate that zinc-mediated lysosomal activation by 1H10 enhances the autophagy-lysosomal pathway and attenuates tau pathology in AD models, suggesting that targeting lysosomal function may represent a potential therapeutic strategy for neurodegenerative disorders characterized by impaired proteostasis.\n\nID: 42410910\nTitle: Targeting the SNAI1-LAMP3 axis to restore lysosomal function and alleviate autophagic flux impairment to delay retinal degeneration.\nAbstract: Retinal degenerative diseases are a leading cause of irreversible blindness. Their pathogenesis is intricately linked to oxidative stress-induced dysfunction of retinal pigment epithelial (RPE) cells and subsequent retinal degeneration. Macroautophagy/autophagy, a critical cellular degradation pathway, plays a vital role in maintaining RPE homeostasis, yet its dysregulation in retinal degenerative diseases remains poorly understood. In this study, we observed that sodium iodate (NaIO3), an oxidative stress inducer, triggered lysosomal dysfunction via lysosomal membrane permeabilization (LMP), thereby impairing autophagic flux in RPE cells and exacerbating retinal degeneration. RNA sequencing identified LAMP3 (lysosomal-associated membrane protein 3) as a downregulated gene following NaIO3 treatment. Functionally, LAMP3 overexpression alleviated NaIO3-induced LMP, improved lysosomal function, and alleviated autophagic impairment. Furthermore, upregulation of LAMP3 reduced oxidative stress and apoptosis in RPE cells, while alleviating retinal degeneration in a NaIO3-induced mouse model. Mechanistically, our data suggested that NaIO3 upregulated the transcription factor SNAI1, which acts as a transcriptional repressor of LAMP3. SNAI1 knockdown increased LAMP3 expression, thereby facilitating the recovery of lysosomal function and the alleviation of autophagic impairment. Collectively, our findings indicate that the SNAI1-LAMP3 axis contributes to the regulation of the autophagy-lysosomal pathway in retinal degeneration, highlighting a potential therapeutic target for delaying disease progression.Abbreviations: AMD: age-related macular degeneration; AO: acridine orange; Baf A1: bafilomycin A1; BAX: BCL2-associated X protein; BCL2: B cell leukemia/lymphoma 2; BSA: bovine serum albumin; CCK-8: cell counting kit-8; ChIP: chromatin immunoprecipitation; CM-H2DCFDA: chloromethyl-2',7'-dichlorodihydrofluorescein diacetate; CTSD: cathepsin D; DAPI: 4',6-diamidino-2-phenylindole; DEGs: differentially expressed genes; DHE: dihydroethidium; EdU: 5-ethynyl-2'-deoxyuridine; ERG: electroretinography; GSEA: gene set enrichment analysis; H&E: hematoxylin and eosin; HsRPE: human primary retinal pigment epithelial; JC-1: 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolylcarbocyanine iodide; LAMP1: lysosomal-associated membrane protein 1; LAMP2: lysosomal-associated membrane protein 2; LAMP3: lysosomal-associated membrane protein 3; LGALS3: lectin, galactose binding, soluble 3; LLOMe: leu-leu methyl ester; LMP: lysosomal membrane permeabilization; MAP1LC3B/LC3B: microtubule-associated protein 1 light chain 3 beta; MMP: mitochondrial membrane potential; NAC: N-acetyl-L-cysteine; NaIO3: sodium iodte; NC: negative control; OCT: optical coherence tomography; PCA: principal component analysis; PI: propidium iodide; qRT-PCR: quantitative real-time polymerase chain reaction; Rapa: rapamycin; ROS: reactive oxygen species; RP: retinitis pigmentosa; RPE: retinal pigment epithelium; RPE65: retinal pigment epithelium 65; siRNA: small interfering RNA; SNAI1: snail family zinc finger 1; SQSTM1/p62: sequestosome 1; TJP1/ZO-1: tight junction protein 1; ZNF135: zinc finger protein 135.\n\nID: 42400323\nTitle: A PARK9 iPSC-Derived Dopaminergic Neuron Model Enables Drug Screening Targeting Autophagy-Lysosome Pathway Dysfunction in Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is a neurodegenerative disease characterized by dopaminergic neuronal degeneration in the substantia nigra, in which lysosomal dysfunction and impaired autophagy-lysosome pathway activity are increasingly recognized as important pathogenic mechanisms. However, disease-modifying therapies targeting this pathway remain unavailable. Here, we generated induced pluripotent stem cells (iPSCs) from a PARK9 patient carrying an ATP13A2 mutation and established mutation-corrected isogenic control iPSCs. PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification, reduced mature cathepsin D levels, CD63-positive vesicle accumulation, LC3B-positive autophagosome accumulation, cytoplasmic pSer129 \u03b1-synuclein accumulation, and increased cleaved caspase-3 signals. These phenotypes were ameliorated in mutation-corrected neurons, supporting the contribution of ATP13A2 dysfunction to these abnormalities. We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation. Among these, paroxetine, Ro 25-6981, amisulpride, and PK11195 showed additional, compound-dependent effects on PARK9-associated phenotypes, including lysosomal acidification, CD63-positive vesicle accumulation, cytoplasmic pSer129 \u03b1-synuclein signals, and cleaved caspase-3 signals. These findings establish PARK9 iPSC-derived neurons as a useful model of lysosomal dysfunction-associated PD pathology and provide a practical screening platform for identifying candidate compounds that modulate autophagy-lysosome pathway-related cellular phenotypes.\n\nID: 42386657\nTitle: The SQSTM1 L341V Variant Associated With Sporadic ALS Promotes the Accumulation of Enlarged Ubiquitin-Positive SQSTM1 Bodies.\nAbstract: SQSTM1 is one of the causative genes of neurodegenerative disorders, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). The SQSTM1 protein regulates the degradation of polyubiquitinated proteins and autophagosome formation through its interaction with microtubule-associated protein light chain 3 (MAP1LC3/LC3). However, the molecular mechanisms by which SQSTM1-LC3 binding regulates the autophagy-endolysosomal system (APELS) remain unclear. To elucidate the spatiotemporal role of SQSTM1, we transiently expressed wild-type SQSTM1 or missense mutants carrying mutations in the LC3-interacting region (LIR), fused with the photoconvertible fluorescent protein Dendra2. Live-cell fluorescence imaging and co-localization analyses with markers of the APELS were then performed. Particle analysis of photoconverted or non-photoconverted SQSTM1-positive structures in live cells revealed that the pathogenic L341V variant formed larger structures than the wild-type. Co-localization analyses further showed that both the L341V and artificial LIR3A mutants accumulated in large ubiquitin-positive structures, likely due to impaired localization to autophagosomes. These results suggest that mutations within the LIR differentially affect autophagosome formation and cargo degradation within APELS-related compartments, highlighting the importance of SQSTM1 structural integrity in ALS/FTD pathogenesis.\n\nID: 42561943\nTitle: C9orf72-associated and sporadic FTD patient iPSC-microglia show differences in phagocytosis and gene expression.\nAbstract: C9orf72 hexanucleotide repeat expansion (C9-HRE) is a major genetic cause of amyotrophic lateral sclerosis and frontotemporal dementia (FTD). However, approximately half of the FTD patients are sporadic without a clear genetic background. To compare characteristics of microglia from different FTD subtypes, we generated induced pluripotent stem cell-derived microglia (iMG) from sporadic and C9-HRE-carrying behavioral variant FTD (bvFTD) patients and healthy controls. C9-HRE iMG displayed C9-HRE-associated RNA foci and dipeptide repeat proteins. All bvFTD iMG had fewer LAMP2-A-positive vesicles compared to control iMG. Additionally, C9-HRE iMG showed significantly increased LC3BII/I conversion after bafilomycin A1 treatment and altered phagocytic activity. The gene expression profile of C9-HRE iMG only modestly differed from the control iMG, but was greatly different from the sporadic bvFTD patient iMG. Our data show alterations in phagocytic and autophagosomal/lysosomal pathways and gene expression profiles between C9-HRE and sporadic bvFTD iMG for the first time.\n\nID: 42541426\nTitle: Neuroprotective Potential of Spermidine in Drosophila sws Neurodegenerative Model.\nAbstract: Neurodegenerative disorders are characterized by progressive neuronal loss and functional decline, yet effective interventions remain limited. The polyamine spermidine was suggested to exert neuroprotective effects, but its concentration-dependent impact on longevity, neuronal integrity, and behavior remains still not well studied. Here, we investigated the effects of spermidine on lifespan, behavioral responses, brain tissue, target gene expression, and antioxidant status in Drosophila melanogaster model of age-dependent neurodegeneration. Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood. Lifespan analysis revealed that high-dose spermidine (5\u2009mM) reduced survival in both wild-type and sws1 mutants, whereas lower doses (0.5 and 1\u2009mM) significantly improved survival in mutants without affecting wild-type flies. Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations. Histological analysis of 10-13-day-old mutants showed a concentration-dependent reduction in degeneration zones within the lamina and medulla at 0.5 and 1\u2009mM, whereas 5\u2009mM had no effect. Biochemical assays indicated mild pro-oxidant effects at 5\u2009mM, reflected by increased malondialdehyde (MDA) levels, while 0.5\u2009mM enhanced antioxidant defenses, including catalase activity and Trolox equivalent antioxidant capacity (TEAC). Our results suggest that spermidine at low doses has the potential to be a general-purpose neuroprotector.\n\nID: 42539062\nTitle: Shared lipidome and proteome signatures of frontotemporal lobar degeneration and Alzheimer's disease.\nAbstract: Frontotemporal lobar degeneration (FTLD) and Alzheimer's disease (AD) differ in their clinical features and genetic etiologies but share progressive cognitive decline. Emerging evidence implicates lipid dysregulation in neurodegeneration, but its extent across FTLD subtypes and how it compares to AD are unclear. Here, we performed integrated lipidomic and proteomic analyses of matched frontal (disease-vulnerable) and occipital (relatively spared) post-mortem cortices from individuals with genetic and sporadic FTLD-TDP, FTLD-tau (Pick's disease, PiD), AD, and controls. FTLD and AD exhibited convergent lipid alterations, including reduced levels of cardiolipins and phosphatidylethanolamines, alongside increased gangliosides, diacylglycerols, cholesterol esters, acylcarnitines, and coenzyme Q, with generally greater changes in FTLD frontal cortex. FTLD displayed additional alterations, including reductions in bis(monoacylglycerol)phosphate, ceramides, phosphatidylserines, phosphatidylinositols, and sulfatides. These lipid changes were accompanied by proteomic alterations involving lysosomal proteins, phospholipases, phospholipid remodeling enzymes, and fatty acid oxidation pathways. Although lipidomic and proteomic signatures were broadly shared across FTLD subtypes, GRN associated FTLD-TDP and PiD showed the most extensive alterations. Triglycerides were selectively reduced in PiD in association with decreased DGAT1 expression, whereas cholesterol esters were elevated across all subtypes except C9orf72 associated FTLD-TDP. These findings identify shared disruptions in lipid homeostasis and lysosomal lipid metabolism across FTLD and AD, highlighting convergent metabolic pathways underlying neurodegeneration.\n\nID: 42512450\nTitle: Molecular Mechanisms of Neurodegenerative Diseases: Emerging Biomarkers and Therapeutic Targets.\nAbstract: Neurodegenerative diseases (NDs), such as Alzheimer's disease (AD), Parkinson's disease (PD), Amyotrophic lateral sclerosis (ALS), and Huntington's disease (HD), involve the gradual loss of structure or function of neurons in the nervous system and are an increasing threat to the aging population worldwide. Although these disorders have different clinical features which affect cognition, movement and other vital body functions, they share key underlying molecular and cellular processes. This starts with protein misfolding and aggregation, mitochondrial dysfunction, oxidative stress, dysregulated protein homeostasis, neuroinflammation, and disrupted cell death pathways. Recent findings have added disease-specific processes, like amyloid-\u03b2 and tau aggregates in AD, \u03b1-synuclein aggregation and mitophagy failure in PD's, TDP-43-related impaired RNA metabolism in ALS, and mutant huntingtin causing transcription aberrations in HD. Protein interactome network analysis showed mechanistic crosstalk between pathogenic proteins of AD and PD. New evidence highlights how lysosomal dysfunction, endoplasmic reticulum stress, and microglial activation, act as a common axis in neurodegeneration. Advancements in genomics and epigenomics have found shared genetic risk loci and regulatory processes that affect how diseases develop and progress. Simultaneously, new biomarkers like circulating microRNAs, exosome-related pathological proteins, neurofilament light chain, inflammatory cytokines, and microglial activation markers are powering early diagnosis tools and disease variations. New imaging techniques also allow for the identification of protein aggregations before symptoms appear. Overall, these findings are accelerating targeted treatments and personalized medicine aimed at disease progression. This review highlights current insights into the molecular mechanisms of NDs and discusses new biomarkers and treatment targets that help future diagnostic and treatment strategies.\n\nID: 42465421\nTitle: Shared lipidome and proteome signatures of frontotemporal lobar degeneration and Alzheimer's disease.\nAbstract: Frontotemporal lobar degeneration (FTLD) and Alzheimer's disease (AD) differ in their clinical features and genetic etiologies but share progressive cognitive decline. Emerging evidence implicates lipid dysregulation in neurodegeneration, but its extent across FTLD subtypes and how it compares to AD are unclear. Here, we performed integrated lipidomic and proteomic analyses of matched frontal (disease-vulnerable) and occipital (relatively spared) post-mortem cortices from individuals with genetic and sporadic FTLD-TDP, FTLD-tau (Pick disease's, PiD), AD, and controls. FTLD and AD exhibited convergent lipid alterations, including reduced levels of cardiolipins and phosphatidylethanolamines, alongside increased gangliosides, diacylglycerols, cholesterol esters, acylcarnitines, and coenzyme Q, with generally greater changes in FTLD frontal cortex.

Triglycerides were selectively reduced in PiD in association with decreased DGAT1 expression, whereas cholesterol esters were elevated across all subtypes except C9orf72 associated FTLD-TDP. These findings identify shared disruptions in lipid homeostasis and lysosomal lipid metabolism across FTLD and AD, highlighting convergent metabolic pathways underlying neurodegeneration.\n\nID: 42423109\nTitle: AAV.hBAG3 Gene Therapy Improves Phenotype in a Valosin Containing Protein\u00a0Mouse Model of Hereditary Inclusion Body Myositis.\nAbstract: Mutations in the valosin-containing protein (VCP) gene lead to a hereditary type of inclusion body myositis (hIBM), in which sarcoplasmic and myonuclear inclusions with TAR DNA-binding protein 43 (TDP-43) pathology and mitochondrial abnormalities are observed in histological analysis. Pathophysiological conditions in the cell cause the protein quality control system to depend on the autophagy-lysosome pathway (ALP) for degradation of accumulated misfolded proteins and mitochondrial turnover. BCL2-associated athanogene 3 (BAG3) protein has a role in initiating the ALP. Our aim was to ameliorate disease processes resulting from mitochondrial abnormalities and misfolded protein aggregation by upregulating the ALP through overexpression of human BAG3 (hBAG3). The VCP-A232E mouse, a model for hIBM, received AAVrh74.tMCK.hBAG3 systemically at 3 months of age, and outcome measures, including functional, histological, and molecular studies, were assessed 9 months post-gene delivery. hBAG3 treatment improved treadmill running distance and rotarod duration, reduced the number of TDP-43-positive aggregates, and decreased the number of fibers showing abnormalities in mitochondrial enzyme histochemistry, compared with the untreated cohort. Moreover, hBAG3 gene therapy resulted in improvements in mitophagy and mitochondrial homeostasis observed as increased levels in mitophagy markers Parkin and Bnip3, mitochondria biogenesis marker Pgc1\u03b1 and mitochondrial DNA-encoded subunits of complex IV, Cox1 and Cox3. In addition, the LC-II/I ratio increased, indicating increased autophagic flux. Our study presents evidence that the strategy of supporting the ALP system by overexpressing BAG3 has potential therapeutic use for myodegenerative conditions associated with abnormal protein aggregates and mitochondrial turnover.\n\nID: 42411953\nTitle: Reduced Soluble Ubiquilin2 in Amyotrophic Lateral Sclerosis Carrying Ubiquilin2 (P494L) Mutation: Clinicopathological and Biochemical Evidence From an Autopsy Case.\nAbstract: We report the clinicopathological and biochemical findings of ALS associated with a UBQLN2 P494L mutation. Autopsy revealed widespread TDP-43 pathology and UBQLN2-positive inclusions. Immunoblot analysis demonstrated a marked reduction of soluble UBQLN2, supporting functional UBQLN2 insufficiency as a pathogenic mechanism underlying TDP-43 aggregation.\n\nID: 42387584\nTitle: SGK1-mediated deficits in microglial phagocytosis drive pathological progression in amyotrophic lateral sclerosis.\nAbstract: Alterations in microglial function and transcriptomic profiles are major pathological hallmarks of amyotrophic lateral sclerosis (ALS). However, the dynamics and regulatory mechanisms underlying microglial phagocytic activity during disease progression remain unclear. In this study, we observed stage-dependent alterations in microglial phagocytic activity during disease progression in SOD1G93A mice. Single-cell RNA sequencing suggested that this change was associated with a reduced abundance of microglial subpopulations enriched for phagocytosis-related pathways. Transcriptomic analysis identified serum- and glucocorticoid-regulated kinase 1 (SGK1) as a potential mediator of this process. Notably, sgk1 knockout in SOD1G93A mice was associated with improved microglial clearance of myelin debris and reduced aberrant engulfment of neuronal material after disease onset. Our results further showed that, after disease onset, the accumulation of myelin debris and apoptotic neurons induced SGK1 upregulation in microglia from SOD1G93A mice. Mechanistically, SGK1 appeared to promote lipid accumulation in microglia by suppressing lipophagy, thereby impairing the ability of microglia to clear cellular debris. Moreover, pharmacological inhibition of SGK1 with GSK650394 attenuated motor deficits and prolonged survival in SOD1G93A mice. Together, our findings provide evidence for a previously unrecognized role of SGK1 in regulating microglial phagocytosis in ALS models and support SGK1 as a potential therapeutic target in SOD1 mutation-associated ALS models.\n\nID: 42365390\nTitle: Lysophagy protects against ANXA11 amyloid fibril toxicity and propagation in FTLD.\nAbstract: Accumulation of Annexin A11 (ANXA11) aggregates is a distinct pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). While genetic studies have linked ANXA11 mutations (e.g., D40G) to disease, the precise molecular events converting aggregation into neurotoxicity and intercellular propagation remain elusive. We hypothesize that lysosomal integrity serves as a critical checkpoint in ANXA11 proteinopathy and that its failure drives disease progression. To model the human pathology of ANXA11, we generated pre-formed fibrils (PFFs) of wild-type and FTLD/ALS-linked D40G mutant ANXA11. Human iPSC-derived neurons, 3D cerebral organoids, and bulk RNA-sequencing were employed to investigate neurotoxicity. High-resolution imaging, lentiviral knockdown, and biochemical assays were performed to delineate the lysosomal damage response and the subsequent \"prion-like\" spreading of aggregates. The internalized ANXA11 fibrils accumulated in lysosomes, triggering lysosomal membrane permeabilization (LMP). The D40G mutation exacerbated this toxicity, leading to severe LMP, mitochondrial depolarization, and specific transcriptional downregulation of the dynactin subunit ACTR10. Mechanistically, we identified a protective signaling axis involving p38 MAPK, MK2, and HSP27 that senses ANXA11-induced lysosomal damage and initiates lysophagy. Notably, in human cerebral organoids, failure of this lysophagic clearance facilitated the cytoplasmic escape of ANXA11, thereby accelerating its seeding activity and propagation to neighboring cells. Pharmacological or genetic modulation of this pathway significantly altered neuronal survival. Our study established lysosomal rupture as a primary driver of ANXA11-associated neurodegeneration and validated the p38/MK2/HSP27 axis as a crucial defense mechanism in human neural tissue. These findings provide a novel mechanistic link between lysosomal quality control and ANXA11 propagation, highlighting that enhancing lysophagic flux represents a promising translational strategy to halt the progression of FTLD and ALS.\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: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.\n\nID: 42350373\nTitle: Karyoptosis mediates cell death and neurodegeneration upon proteotoxic stress.\nAbstract: Neurodegenerative diseases are frequently associated with proteotoxic stress linked to disease specific proteins. The autophagy-lysosome system provides essential control of proteotoxic stress and its failure can lead to initiation of apoptosis. However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts. Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material. We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation. We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology. Finally, we identify karyoptotic features in post-mortem frontal cortex of FTD and Alzheimer's disease (AD) patients. Together these findings characterise a form of cell death directly linked to proteotoxic stress and nuclear lamina stability that is associated with neurodegeneration.\n\nID: 42331066\nTitle: Fibroblasts carrying intermediate C9orf72 hexanucleotide repeat expansions from iNPH patients show changes in energy metabolism but no cell pathologies.\nAbstract: Long C9orf72 hexanucleotide repeat expansions (C9-HRE) are the most common genetic cause of frontotemporal dementia (FTD), a group of neurodegenerative syndromes leading to cognitive dysfunction and frontal and temporal atrophy. FTD is a potential comorbidity of idiopathic normal pressure hydrocephalus (iNPH) and carrying the C9-HRE can modify the age-of-onset in iNPH patients. While intermediate-length C9-HRE (<30 repeats) are often considered non-pathogenic, the exact pathological cutoff is unclear. In this study, we assessed whether skin fibroblasts from iNPH patients carrying intermediate C9-HRE display C9-HRE-associated pathological hallmarks and changes in cellular function. C9-HRE-associated RNA foci, present in the long (>60 repeats) C9-HRE carrier fibroblasts, were not detected in those of the intermediate carriers. The number of p62-positive puncta was significantly increased in long but not intermediate C9-HRE carrier fibroblasts, in line with p62-positive intracellular inclusions observed in a brain biopsy from the patient. Induction of autophagy did not suggest any defects in the intermediate carrier fibroblasts. Fibroblasts from the intermediate C9-HRE carriers showed upregulated glycolytic activity, possibly to counteract the slightly reduced mitochondrial respiration. This could not be observed in the long C9-HRE carrier fibroblasts. In conclusion, these data suggest that while the long C9-HRE leads to more severe cellular pathologies than intermediate C9-HRE, the latter might predispose cells to deficits in specific cellular functions, such as energy metabolism.\n\nID: 42282588\nTitle: From anti-fungal to potential neurotherapeutic: Posaconazole as an effective inhibitor of cellular TDP-43 pathology.\nAbstract: Recently, we showed that ketoconazole, a known anti-fungal inhibitor of CYP51, stabilized TAR DNA-binding protein 43 (TDP-43) native self-interactions, reduced TDP-43 pathology and rescued TDP-43-induced SREBP2 downregulation. Despite its promising effects, ketoconazole is not viable for repurposing for ALS due to liver toxicity side effects that occur when orally delivered. To address this, we tested the activities of seven additional known azole-based CYP51 inhibitors in order identify a viable alternative to ketoconazole. Using our established TDP-43 mislocalization and aggregation assay in HEK293T cells, we identified posaconazole, an FDA-approved, CNS-penetrant and orally delivered anti-fungal, as the strongest inhibitor of TDP-43 pathology. Posaconazole was able to reduce insoluble TDP-43 and restore SREBP2 levels, outperforming ketoconazole. Mechanism of action (MOA) experiments suggest posaconazole is able to outperform ketoconazole by inducing a significantly stronger activation of autophagy and upregulation of heat shock proteins known to clear TDP-43. Further MOA experiments show that the effects of posaconazole on TDP-43 are dependent on its known ability to lower cellular cholesterol levels. By correlating our experimental results on the eight CYP51 inhibitors tested, we show that predicted affinity towards human CYP51 strongly correlates with the inhibitors' ability to lower TDP-43 aggregation and mislocalization. Finally, we tested posaconazole in a low dose sodium arsenite ALS model in iPSC-derived motor neurons, showing that it is efficacious at inhibiting TDP-43 pathology in the nanomolar range. Altogether, these results support the repurposing of posaconazole for ALS/FTD as a means to prevent TDP-43 pathology.\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: 42264187\nTitle: Nanodelivery strategies for caloric restriction mimetics in age-associated neurodegeneration.\nAbstract: Brain aging is associated mainly with a decline in cognitive function and is a major risk factor for various neurodegenerative disorders (NDDs). Major hallmarks of aging include oxidative stress, chronic neuroinflammation, mitochondrial dysfunction, and impaired proteostasis. Although caloric restriction (CR) has consistently demonstrated neuroprotective effects, its long-term effects in humans remain challenging. Consequently, CRMs such as metformin, spermidine, and curcumin have been widely used because of their ability to recapitulate key molecular effects of CR. Despite their therapeutic effects, the clinical translation of CRMs is significantly limited by their poor bioavailability, rapid metabolism, low aqueous solubility, and inefficient penetration across the blood-brain barrier (BBB). A nanoparticle-based drug delivery system provides a promising approach to address these limitations. Polymeric, liposomal, and lipid-based nanocarriers can be engineered to increase BBB transport via receptor-mediated transcytosis and to enable targeted and sustained drug release. Encapsulation of CRMs within nanoparticles has improved their pharmacokinetic and pharmacodynamic profiles by increasing their stability and bioavailability and reducing systemic degradation. However, targeted delivery of CRMs has been shown to modulate aging-associated pathways, which are necessary for the maintenance of neuronal integrity and synaptic function. This review highlights the potential of CRM-loaded nanocarriers as emerging therapeutic systems to delay brain aging and age-associated disorders. Furthermore, the current challenges and future perspectives on optimizing brain-targeted delivery to enable successful clinical translation in age-related NDDs are discussed.\n\nID: 42247713\nTitle: Beyond brain fog: viral proteins as convergent drivers of neuroinflammation and proteinopathy.\nAbstract: Post-viral neurological syndromes, such as post-acute sequelae of COVID-19, present a paradox of severe symptoms despite minimal CNS viral replication. The 'protein-as-pathogen' model, where shed viral proteins act as soluble neurotoxins, is now central to understanding this phenomenon. This review presents the opinion that the most critical recent developments are not that these proteins are toxic, but how their mechanisms converge. We synthesize evidence from the last two years showing that proteins from diverse, highly infectious virus families with zoonotic potential (e.g. Coronaviridae, Flaviviridae, Orthomyxoviridae) engage shared host pathways. We focus on two convergent mechanisms: (1) the activation of glial Toll-like receptor (TLR)4/TLR2 signaling, which initiates a chronic neuroinflammatory cascade, and (2) the disruption of host proteostasis, which seeds neurodegenerative proteinopathies like alpha-synuclein and tau aggregation. This framework positions post-viral syndromes as mechanistically related disorders and identifies pan-viral therapeutic targets, such as TLR inhibitors and autophagy activators.\n\nID: 42215790\nTitle: The C9orf72/SMCR8 complex maintains microglial homeostasis via RAB8A-ESCRT-mediated lysosomal repair.\nAbstract: Microglia are critical regulators of neuroinflammation and neurodegeneration. Haploinsufficiency of C9orf72, the most frequently mutated gene in\u00a0amyotrophic lateral sclerosis and frontotemporal dementia, has been linked to autophagy-lysosomal pathway defects, but the role\u00a0of C9orf72 in microglia remains unclear. Here, we identify the C9orf72/SMCR8 complex as a key regulator of microglial homeostasis through promoting lysosomal membrane repair. Loss of C9orf72 and SMCR8 in mice causes age\u2011dependent neuroinflammation and microgliosis, with microglia adopting a disease-associated state. In aged brain and spinal cord tissue, microglia display lysosomal damage marked by galectin\u20113 accumulation. Using a lysosomotropic agent to induce lysosomal damage in microglia, we find that C9orf72/SMCR8-deficient cells accumulate damaged lysosomes and show defective recruitment of phosphorylated RAB8A and the Endosomal Sorting Complexes Required for Transport (ESCRT) machinery\u00a0to damaged lysosomes. Notably, mutant microglia accumulate GTP\u2011bound RAB8A, which becomes hyperphosphorylated and mislocalized to RAB7-positive, LAMP1-negative vesicles. The GTPase-activating activity of the C9orf72/SMCR8 complex is essential for lysosomal repair. Our findings reveal that the C9orf72/SMCR8 complex coordinates RAB8A-ESCRT-mediated lysosomal repair to safeguard microglial homeostasis and limit neuroinflammation.\n\nID: 42167675\nTitle: TDP-43: a critical amplifier of Alzheimer's disease beyond amyloid and tau.\nAbstract: TAR DNA-binding protein 43 (TDP-43) proteinopathy has recently emerged as a pivotal, yet underrecognized, contributor to the multifaceted neuropathology of Alzheimer's disease (AD). While amyloid-\u03b2 and tau have long been established as cardinal pathological hallmarks, growing evidence delineates TDP-43 as a critical participant of neurodegeneration, intricately interwoven with amyloid and tau pathologies. TDP-43 mislocalization, post-translational modifications, and aggregation potentiate neuronal loss through disruption of RNA metabolism, nucleocytoplasmic transport, and protein homeostasis. This tripartite interplay manifests in synergistic and possibly multidirectional pathological cascades that amplify neuronal vulnerability and cognitive decline, thereby complicating the clinical and pathological complexity of AD. Here, we critically reviewed the mechanistic crosstalk among TDP-43, amyloid-\u03b2, and tau, focusing on preclinical and clinical evidence, highlighting possible convergent pathways of aggregation, propagation, and neurodegeneration. Moreover, this review also evaluates mitochondrial dysfunction, autophagy failure, and inflammation as underlying events associated with TDP-43 pathology. Therefore, we argue for a reconceptualization of AD as a dynamic proteinopathy network, with TDP-43 as a core integrative node influencing disease onset and its progression. Notably, we discuss emerging diagnostic modalities associated with molecular tracers of TDP-43, providing prospects for future biomarker identification. Finally, this review articulates the translational relevance of TDP-43 therapy in AD and related neurological disorders, emphasizing the necessity of holistic approaches that transcend the traditional amyloid-tau paradigm to effectively tackle the full spectrum of AD pathobiology.\n\nID: 42164014\nTitle: Symptom-Level Precision Neurology in Amyotrophic Lateral Sclerosis (ALS): Linking Microglial Pruning, Mitochondrial Nicotinamide Adenine Dinucleotide (NAD+) Compensation, and Autophagy Failure Across the Aging Spectrum.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a heterogeneous neurological disease with limited disease-modifying treatment options and, for many patients, a short survival window. The clinical course varies widely. Limb weakness, bulbar impairment, respiratory decline, fine-motor dysfunction, cognitive change, mood symptoms, and fatigue may each appear at different times and progress at different rates. This variability suggests that motor neuron loss alone may not fully explain the patient-level pattern of symptoms. This article is a narrative hypothesis framework, not a clinical guideline or a validated stratification tool. Established ALS biology, associative genomic findings, preclinical observations, computational predictions, and author-derived hypotheses are therefore separated throughout the article. This review brings together four interlinked studies by the current author as a primary hypothesis-generating corpus, which proposes that synaptic plasticity fragility may initiate a microglial pruning continuum shared by major depressive disorder and ALS, while ALS-specific progression may depend on mitochondrial stress, oxidized nicotinamide adenine dinucleotide (NAD+) compensation failure, and collapse of autophagy under aging-related limits. The model presented here maps symptom domains to vulnerable circuit compartments and separates three broad biological states: compensated plasticity, fragile plasticity, and network collapse. A compact mechanistic formulation is used to describe the balance between pruning pressure, glutamatergic burden, and aging stress on one side, and oxidative phosphorylation capacity, NAD+ reserve, and autophagic clearance on the other. The framework also incorporates opposing phosphoinositide 3-kinase (PI3K)/AKT/mechanistic target of rapamycin (mTOR) and peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1\u03b1) pathway patterns that may distinguish ALS from frontotemporal dementia (FTD) within an aging context. The result is a falsifiable, biomarker-oriented hypothesis model for future studies, not an evidence-based diagnostic or therapeutic algorithm.\n\nID: 42163657\nTitle: Mitochondrial Function in Neurons and Glia in Health and Its Alteration in Parkinson's Disease: A Review.\nAbstract: Mitochondria play an important role in maintaining redox balance, energy, calcium, and the viability of neurons. The mitochondrial dysfunction is one of the primary sources of glial activation and dopaminergic neuron loss in Parkinson's disease (PD). The key biochemical elements of the pathogenesis of PD include impaired oxidative phosphorylation, elevated generation of reactive oxygen species (ROS), and impaired mitophagy. This review is a synthesis and stringent evaluation of recent experimental, clinical and genetic studies relating mitochondrial dysfunction and Parkinson's disease (PD). We examined information on bioenergetics, mitochondrial dynamics, calcium homeostasis, and interactions between neurons and glia. The molecular and therapeutic importance of therapies, such as mitophagy modulators, bioenergetic enhancers, and mitochondrial antioxidants, was investigated. The absence of Complex I, excess ROS, mitochondrial DNA damage, and nonfunctioning fusionfission cycles leads to neurodegeneration. The glial metabolic abnormalities worsen the oxidative stress and neuroinflammation, weakening the support of the neurons. The effects of impaired mitophagy are the accumulation of dysfunctional mitochondria, and the effects of calcium overload disrupt energy metabolism. Neuroprotective effects of such substances as spermidine, urolithin A, resveratrol, \u03b1lipoic acid, MitoQ, SkQ1, or CoQ10 have been shown using preclinical research. Sacrifices such as exercising and proper dieting enable the mitochondria to perform better and become stronger. Mitochondrial dysfunction enhances the progression of PD through oxidative stress, bioenergetic breakdown, and inflammatory signalling. Attention to these related systems is an entire way to alter the direction of a disease. PD can be treated using an increase in mitochondrial quality control, redox regulation, and metabolic efficiency. Continued studies in the framework of precision medicine are required to validate the safety and effectiveness of mitochondrial-targeted medications.\n\nID: 42160303\nTitle: Retraction: Rapamycin and Chloroquine: The In Vitro and In Vivo Effects of Autophagy-Modifying Drugs Show Promising Results in Valosin Containing Protein Multisystem Proteinopathy.\nAbstract: \n\nID: 42143042\nTitle: VCP modulation ameliorates pathological features in C9orf72 models.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are devastating neurodegenerative diseases linked by similar pathological mechanisms, which, in some familial forms, may be associated with the same genetic alterations. Among them, the most common is the C9ORF72 (C9) mutation. The C9 mutation consists in an aberrant expansion of the hexanucleotide repeat (G4C2)n that leads to the production and accumulation of toxic dipeptide repeat proteins (DPRs). Some of these C9-DPRs contribute to neuronal dysfunction and degeneration through different mechanisms. One of these involves alterations in the protein quality control (PQC) system, specifically in the autophagy-lysosomal pathway. Valosin-containing protein (VCP) is a critical component of the PQC system, assisting the degradation of misfolded proteins and damaged organelles and the maintenance of cellular homeostasis. In this study, we investigated the role of VCP in modulating pathological features associated with C9 mutation. Using neuronal cell models, we demonstrated that VCP overexpression significantly reduced C9-DPRs levels. This reduction is mediated by mechanisms involving both the ubiquitin-proteasome system (UPS) and autophagy. Additionally, we also observed that C9-DPRs induce lysosomal damage, which is counteracted by VCP overexpression, as indicated by decreased galectin-3 puncta and restored lysosomal pH. We then pharmacologically activated VCP-mediated clearance through SMER28, increasing the clearance of the most toxic DPR, the polyPR. We also determined that in this model, SMER28 activity is mediated by the UPS and is associated with the mitigation of DPR-induced lysosome damage. Additionally, using motor neurons derived from induced pluripotent stem cells (iPSC-MNs) from C9-ALS mutation carriers, we demonstrated that SMER28 treatment significantly decreased polyGA levels, a marker for C9-DPR accumulation. Moreover, SMER28 rescued C9-MNs commitment to differentiation and the alteration in the expression of autophagy-related genes. Taken together, our findings strongly support VCP as a modulator of C9 pathology and highlight its potential as a therapeutic target.\n\nID: 42097046\nTitle: BAG3V468M impairs proteasomal protein clearance and induces dilated cardiomyopathy in vivo.\nAbstract: Idiopathic dilated cardiomyopathy (DCM) is one of the major causes of heart failure, characterized by left ventricular dilation and systolic dysfunction in the absence of an identifiable cause, and is associated with reduced life expectancy. Genetic studies, including genome-wide association studies, have identified variants in BAG3, a key regulator of protein quality control (PQC), as contributors to both familial and sporadic forms of DCM. Impaired PQC and the accumulation of misfolded proteins (proteinopathy) have emerged as potential pathogenic mechanisms. Here, we investigated the molecular consequences of a recently identified BAG3 missense variant (V468\u202fM) associated with familial DCM. To assess the in vivo effects of the variant, human BAG3V468M was ectopically expressed in wild-type zebrafish embryos. Overexpression of BAG3V468M resulted in a DCM-like phenotype characterized by ventricular dilation, reduced heart rate, and impaired contractility. Transmission electron microscopy revealed marked disruption of myocardial ultrastructure and sarcomeric organization. To explore the impact on proteostasis, markers of autophagy (LC3-I/II and p62) were analyzed and showed no significant differences between BAG3V468M and control embryos under basal conditions. In contrast, analysis of the ubiquitin-proteasome system demonstrated a significant accumulation of ubiquitinated proteins in BAG3V468M-expressing embryos, suggesting impaired proteasomal protein clearance or increased proteotoxic stress. Expression of BAG3V468M induces a DCM-like phenotype in vivo associated with disrupted myocardial architecture and altered proteostasis. While canonical autophagy markers remain unchanged, the accumulation of ubiquitinated proteins points toward a disturbance in ubiquitin-mediated protein turnover. These findings implicate mutation-specific alterations in proteostasis as a potential mechanism contributing to BAG3-associated cardiomyopathy.\n\nID: 42092406\nTitle: TRIM16 attenuates TDP43-mediated oxidative injury by coordinating Nrf2 activation and TFR1 autophagic degradation.\nAbstract: TAR DNA-binding protein 43 (TDP43) aggregation is a well-established pathological hallmark of amyotrophic lateral sclerosis (ALS) and related neurodegenerative disorders, contributing significantly to oxidative stress and neuronal injury. Here, we report that the M337V mutation in TDP43 exacerbates its proteotoxicity relative to the wild-type protein. Concurrently, multi-omics analysis revealed a pronounced downregulation of TRIM16 in motor neuron-like cells expressing either wild-type or M337V mutant TDP43. Functional studies demonstrated that TRIM16 overexpression effectively mitigated oxidative stress, restored mitochondrial integrity, and suppressed ferroptosis. Mechanistically, TRIM16 promoted the ubiquitination and degradation of Keap1, thereby facilitating the activation of Nrf2-mediated antioxidant genes. Furthermore, we identified the iron import receptor TFR1 as a novel ubiquitination substrate of TRIM16. TRIM16 mediated the ubiquitination of TFR1 and targeted it for p62-dependent autophagic degradation, which in turn reduced iron accumulation and lipid peroxidation. Collectively, our findings establish TRIM16 as a pivotal suppressor of TDP43-induced toxicity by orchestrating dual cytoprotective pathways to enhance cellular resilience, highlighting its promising therapeutic potential for TDP43 proteinopathy.\n\nID: 42072687\nTitle: Transcriptomic Analysis Reveals the Beneficial Effects of Spermidine in an ALS Mouse Model.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease marked by progressive degeneration of motor neurons and skeletal muscle. Gene expression analysis of the spinal cord and gastrocnemius of the SOD1-G93A ALS mouse model revealed a strong increase in inflammatory pathways and, specifically in the ALS gastrocnemius, a decrease in mitochondrial transcription and an increase in ribosomal protein expression. Treatment of ALS mice with the polyamine spermidine (SPD), a promising molecule in combating neurodegeneration and muscle atrophy, is able to partially restore the expression of more than four thousand genes in gastrocnemius tissue, including the mitochondrial regulator Pgc1\u03b1, as well as all the mitochondrial encoded genes and a large class of ribosomal proteins. SPD enhanced mitochondrial bioenergetics, as evidenced by Seahorse experiments, and delayed muscle weakness in vivo, as shown by grip strength records. These findings suggest that SPD can act as a potential supplement in the therapeutic strategy for ALS, offering a foundation for further research to improve patient outcomes.\n\nID: 42063624\nTitle: Amyloid beta pathology induces astrocytic pTDP-43 mislocalization and disrupts TDP-43-regulated cryptic exon transcripts.\nAbstract: While amyloid-\u03b2 (A\u03b2) and tau are hallmark pathologies of Alzheimer's disease (AD), TDP-43 proteinopathy is increasingly recognized as an important contributor, occurring in up to 57% of AD cases and associated with accelerated cognitive decline. TDP-43 regulates RNA splicing, and its mislocalization leads to cryptic exon inclusion and loss of canonical protein function. While neuronal TDP-43 pathology has been well studied, its role in astrocytes remains less understood. Recent findings suggest increased phosphorylated TDP-43 (pTDP-43) inclusions in astrocytic endfeet in AD and a bidirectional interaction between A\u03b2 and TDP-43, promoting mutual aggregation. We analyzed pTDP-43 immunoreactivity (IR) in astrocytic perivascular end-feet, nuclei, and cytosol in hippocampal sections from 3-month-old and 18-month-old AppNL-F/NL-F mice and 18-month-old wild-type controls using ImageJ. In vitro, primary fetal human astrocytes were exposed to oligomeric A\u03b242, and changes in cytosolic and nuclear pTDP-43 IR were quantified via ImageJ, while TDP-43 and pTDP-43 protein levels were measured using an in-house ELISA. Expression of canonical transcripts ATG4B and KALRN, involved in autophagy and synaptic support, was assessed by qPCR. Corresponding protein-level changes were evaluated using in-house ELISA. Our findings demonstrate significantly higher pTDP-43 accumulations in astrocytic nuclei, cytosol, and endfeet in 18-month-old AppNL-F/NL-F mice compared to age-matched wild-type mice. Astrocytes exposed to oligomeric A\u03b242 showed elevated cytosolic pTDP-43 IR and total pTDP-43 protein levels. Concurrently, expression of canonical ATG4B and KALRN transcripts was significantly reduced, which was accompanied by corresponding decreases in protein levels. Our findings demonstrate that pTDP-43 accumulates in astrocytic nuclei, cytosol, and endfeet in the presence of AD pathology. The observed A\u03b2-induced increase in cytosolic pTDP-43 and transcript disruption suggests a mechanistic link contributing to autophagy impairment and cytoskeletal changes in astrocytes, potentially exacerbating AD progression.\n\nID: 42035925\nTitle: Galectins as stress-integrating regulators of neuroimmune signaling and proteinopathy in the central nervous system.\nAbstract: Galectins are \u03b2-galactoside-binding lectins that play increasingly mechanistic functions in central nervous system (CNS) physiology and disease. Over the past decade, a rapidly expanding literature has identified galectins as regulators of microglial activation, misfolded protein pathology, vesicle damage sensing, autophagy, synaptic plasticity, myelination, vascular repair, and neuroimmune communication. Galectins operate across intracellular and extracellular compartments to integrate cellular stress and innate immune signaling. Here, we review CNS studies of galectin-1, galectin-3, galectin-4, galectin-8, and galectin-9, focusing primarily on work published from 2019 onward while incorporating selected earlier studies to establish foundational concepts. Across experimental models and human studies, galectins orchestrate microglial state transitions, regulate aggregation and propagation of amyloid-\u03b2, tau, \u03b1-synuclein, and mutant huntingtin, and function as intracellular sensors of vesicle and lysosomal damage. Multiple studies further establish galectins as biomarkers and therapeutic targets across Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, stroke, traumatic brain injury, spinal cord injury, retinal degeneration, and chronic pain. Importantly, this review highlights a stage- and context-dependent paradox in which the same galectin axis can amplify neuroinflammation and proteopathic spread in some settings yet support recovery or tissue protection in others. Together, these findings position galectins as central regulators that convert intracellular stress into coordinated neuroimmune programs shaping proteinopathy, circuit dysfunction, and tissue remodeling.\n\nID: 42607684\nTitle: ER-liquid condensate contacts sequester FAM134B/C and RhoA to govern cell morphology.\nAbstract: Endoplasmic reticulum (ER)-phagy receptors have elusive physiological functions beyond ER remodeling. To gain insight into these, we screen for cytoplasmic interactors of well-known receptors in mouse pancreatic ductal adenocarcinoma cells. Our data subsequently reveal a non-canonical action of PRKAR1A, a subunit of protein kinase A (PKA), in binding and activating FAM134B/C. At a molecular level, an amphipathic helix in the otherwise-disordered C terminus of FAM134B directly binds PRKAR1A dimers. Multimodal imaging reveals that this interaction occurs at interorganellar contact sites between the ER and liquid-like condensates of PRKAR1A. Mechanistically, ER-condensate contacts promote clustering of FAM134B/C with LC3B and recruit lysosomes, forming degradation hubs. Unexpectedly, these structures are found to control cytoplasmic signaling through FAM134B/C-mediated lysosomal sequestration of RhoA. Underscoring the physiologic relevance of this, these cytoplasmic-facing actions of FAM134B/C result in RhoA-dependent cell morphologic and migratory control in response to cyclic AMP (cAMP) stimuli. Thus, interorganellar contacts expand the roles of FAM134B/C ER-phagy receptors beyond ER degradation.\n\nID: 42598912\nTitle: A live-cell autophagy reporter reveals reversible vacuolation in naked mole-rat skin fibroblasts under lysosomal stress.\nAbstract: Naked mole-rats (NMRs, Heterocephalus glaber) display unusual longevity and resistance to age-related decline, and accumulating evidence suggests that their autophagy-lysosome pathway (ALP) is regulated differently from that of conventional mammalian models. However, most studies in NMR cells have relied on static biochemical or ultrastructural readouts, leaving the dynamic organisation of autophagy in living cells poorly defined. Here, we establish a stable tandem fluorescent autophagy reporter in NMR skin fibroblasts using an mCherry-EGFP-LC3NMR construct to enable live-cell, single-cell resolution analysis of ALP dynamics. Under basal conditions, NMR skin fibroblasts exhibit a greater abundance of LC3-positive structures than HeLa cells, together with a mixed population of autophagosomes and autolysosomes, indicating a distinct steady-state organisation of the ALP. Chloroquine (CQ)-induced lysosomal stress caused the expected accumulation of LC3-positive structures but also triggered the formation of large cytoplasmic vacuoles in NMR skin fibroblasts. Importantly, this vacuolation was not associated with acute cytotoxicity and progressively resolved following CQ removal, accompanied by reorganisation of LC3-positive compartments and recovery of lysosomal acidity. Electron microscopy showed that CQ-induced vacuoles are membrane-bound, containing internal material and co-existing with multiple ALP-related vesicular compartments. Primary NMR skin fibroblasts display a similar vacuolation phenotype, indicating that this response is not an artefact of immortalisation or reporter expression. Together, these findings establish a live-cell platform for analysing autophagy in NMR cells and identify a distinctive, reversible vacuolation response to lysosomal stress, consistent with dynamic remodelling of the lysosomal system within NMR skin fibroblasts.\n\nID: 42598038\nTitle: LDH-mediated autophagic full-chain blockade for Multiple Myeloma treatment by targeting circ_0008255/miR-192-5p/ATG2A axis.\nAbstract: Multiple myeloma (MM) is an incurable plasma cell malignancy with limited therapeutic options. Although autophagy dysregulation is implicated in MM pathogenesis, its precise regulation, particularly by circular RNAs (circRNAs), is poorly understood. Through clinical RNA sequencing of primary MM patient samples, we identify an autophagy-associated circRNA, circ_0008255, which is markedly upregulated in MM patients and closely correlated with poor disease prognosis. Functional studies reveal that circ_0008255 promotes MM proliferation and tumor growth by enhancing autophagic activity. Mechanistically, it functions as a competitive endogenous RNA for miR-192-5p, leading to elevated expression of the core autophagy protein, autophagy related 2 homolog A (ATG2A). Furthermore, we developed a biomimetic nanoplatform based on layered double hydroxide (LDH) nanosheets coated with myeloma-derived cell membranes for tumor-specific delivery. This system co-delivers siRNA targeting circ_0008255 to suppress autophagosome initiation, while simultaneously leveraging the lysosome-alkalinizing property of LDH to impair autophagosome-lysosome fusion. Together, these actions enforce a synergistic autophagic full-chain blockade, leading to potent antitumor effects in vitro and in vivo. Overall, our study reveals a central regulatory role of circ_0008255 in myeloma autophagy, offering a promising therapeutic paradigm for MM.\n\nID: 42596071\nTitle: An expanding role for ATG8s and ATG8 E3-like ligases in maintaining membrane integrity.\nAbstract: Endolysosomal membranes are frequently damaged by pathogenic stress associated with aging, infection, and neurodegeneration, and failure to repair such damage leads to inflammation and cell death. Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration. Beyond its canonical role in macroautophagy, membrane atg8ylation also occurs on preexisting, non-autophagosomal single membranes through Conjugation of ATG8s to Single Membranes (CASM), positioning this pathway as a rapid response to membrane stress. Two E3-like ligase complexes, ATG16L1-ATG5-ATG12 and TECPR1-ATG5-ATG12, act as complementary sensors of lysosomal injury by detecting distinct physicochemical cues, including proton gradient collapse and lipid scrambling. These ligases convert damage signals into spatially restricted membrane atg8ylation, generating a membrane-associated platform that coordinates multiple downstream pathways. These include ESCRT-dependent membrane repair, ER-lysosome lipid transfer, membrane tubulation, and stress granule formation. When repair fails, membrane atg8ylation regulates lysophagy and activates lysosomal biogenesis and regeneration to restore lysosomal homeostasis. These emerging findings define membrane atg8ylation as a central organizer of membrane quality control rather than a pathway merely confined to macroautophagy. In this review, we summarize the current understanding of how membrane atg8ylation detects lysosomal damage and how this pathway coordinates other lysosomal quality control mechanisms to maintain lysosomal integrity.\n\nID: 42594853\nTitle: Beyond the ATP-binding pocket: emerging strategies in kinase targeting from allosteric inhibition to targeted protein degradation.\nAbstract: Protein kinases are central regulators of cellular signaling and remain a major target class in precision medicine. While ATP-competitive inhibitors-including conformation-selective and covalent agents-have delivered substantial clinical benefit, durable responses are frequently limited by the conservation of the ATP pocket and the emergence of resistance mutations (e.g. gatekeeper and solvent-front substitutions), as well as kinase noncatalytic functions that are not addressed by enzymatic inhibition alone. Consequently, kinase drug discovery is expanding beyond orthosteric occupancy toward modalities that reprogram kinase conformations or eliminate the target protein. This Review summarizes the structural and medicinal chemistry principles underlying (i) allosteric inhibition and (ii) proximity-induced degradation, with an emphasis on design logic, structure-activity relationships, and key liabilities in the beyond rule of five space. We further highlight enabling technologies-including structural biology, chemical proteomics, and AI/ML-assisted modeling-that support allosteric site identification, ternary complex engineering, and multi-parameter optimization. Finally, we discuss translational challenges for bifunctional molecules, including permeability, exposure-response relationships, off-target degradation, and safety, and propose practical considerations for developing next-generation selective kinase therapeutics.\n\nID: 42593908\nTitle: Selective Brain-Penetrant TTBK1 Inhibitors Modulate TDP-43 Pathology and Rescue Cognitive Deficits in a Mouse Model of TDP-43 Proteinopathy.\nAbstract: Transactive response DNA-binding protein of 43 kDa (TDP-43) is a pathological hallmark of neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Modulation of TDP-43 pathology represents a promising disease-modifying strategy. Tau tubulin kinase 1 (TTBK1) has emerged as a relevant therapeutic target; however, selectivity over the TTBK2 isoform is required to avoid ciliogenesis-related liabilities. Here, we report the discovery of selective, brain-penetrant TTBK1 inhibitors through a structure-guided medicinal chemistry program. Lead compounds exhibit potent and selective TTBK1 inhibition, no impact on ciliogenesis, and central nervous system exposure. We found that these inhibitors reduce TDP-43 phosphorylation levels in neuroblastoma cells and FTD patient-derived models. The optimized lead compound demonstrated a brain-to-plasma ratio of 3:1, a maximum tolerated dose, and a wide therapeutic window. In vivo, administration restored cognitive deficits, conferred neuroprotection in the frontal cortex, and reduced microglial activation in an FTD-TDP mouse model, supporting its therapeutic potential.\n\nID: 42591164\nTitle: Podocyte-specific acid sphingomyelinase overexpression promotes gasdermin D dependent pyroptosis by impairing autophagic flux during obesity.\nAbstract: Recent studies suggest that gasdermin D (GSDMD) pore formation contributes to inflammasome-mediated cytokine release and pyroptosis in podocytes under pathological conditions. However, the molecular mechanisms regulating GSDMD pore formation in these cells remain unclear. Given the established role of the lysosomal acid sphingomyelinase (ASM)-ceramide pathway in obesity-related glomerulopathy (ORG), we investigated whether ASM regulates obesity-induced GSDMD pore formation and pyroptosis in podocytes, thereby influencing the progression of ORG. We found that podocyte-specific Smpd1 (the gene encoding ASM) overexpression markedly enhanced high-fat diet (HFD)-induced NLRP3 inflammasome activation, GSDMD N-terminal fragment (GSDMD-NT) generation, and pyroptosis in glomeruli of Smpd1trg/Podocre mice compared to wild-type controls. Pharmacological inhibition of ASM or the NLRP3 inflammasome attenuated these pathological changes in obese mice. In contrast, inhibition of GSDMD pore formation with disulfiram (DIS) prevented HFD-induced pyroptosis without affecting NLRP3 inflammasome activation. Consistently, obesity-induced podocyte injury and glomerulosclerosis were exacerbated by ASM overexpression but alleviated by inhibition of ASM, the NLRP3 inflammasome, or GSDMD pore formation. Using primary podocytes isolated from wild-type, Smpd1 knockout (Smpd1-/-), and Smpd1trg/Podocre mice, we further demonstrated that palmitic acid (PA), an obesity-associated lipotoxic factor, induced NLRP3 inflammasome activation, GSDMD pore formation, inflammasome product release, and pyroptosis. These responses were suppressed by Smpd1 deletion but enhanced by ASM overexpression. Confocal and super-resolution microscopy revealed that PA increased the accumulation of autophagosomes containing GSDMD-NT while impairing lysosome-autophagosome fusion, effects that were mitigated by Smpd1 deletion and amplified by ASM overexpression. To further elucidate the underlying mechanism, we examined whether ASM regulates lysosomal TRPML1 channel-mediated Ca2+ release, thereby controlling lysosome-autophagosome interaction and GSDMD-NT degradation. PA inhibited TRPML1 channel activity in podocytes, an effect that was intensified by ASM overexpression. Furthermore, PA-induced impairment of lysosome-autophagosome interaction and increased GSDMD pore formation were attenuated by the TRPML1 agonist ML-SA5 and exacerbated by the TRPML1 inhibitor ML-SI1. Collectively, these findings indicate that ASM regulates lysosomal function and autophagic degradation of GSDMD-NT, thereby controlling GSDMD pore formation and pyroptosis in podocytes during ORG.\n\nID: 42589464\nTitle: Proteome-Level Autophagy-Lysosome Remodelling Marks Ageing in Human Dermal Fibroblasts and Nominates Hydroxytyrosol as a Candidate Nutraceutical.\nAbstract: Autophagy-lysosome dysfunction accompanies dermal fibroblast ageing, yet whether remodelling is transcriptional or post-transcriptional in primary human cells remains unresolved. We reanalysed the Genetic and Epigenetic Signatures of Translational Ageing Laboratory Testing(GESTALT) paired RNA sequencing (RNA-seq) and tandem mass tag (TMT) proteome from 82 donors (aged 22-89) using Data Integration Analysis for Biomarker discovery using Latent cOmponents (DIABLO) for supervised multi-omics integration, weighted gene co-expression network analysis (WGCNA), external Genotype-Tissue Expression(GTEx) transcriptomic comparison, network medicine proximity mapping and CDOCKER molecular docking. Three analyses converged on the autophagy-lysosome axis: Kyoto Encyclopaedia of Genes and Genomes (KEGG) Lysosome ranked first in discordant-quadrant analysis; gene set enrichment analysis (GSEA) identified vacuole organisation and macroautophagy as the top age-upregulated Gene Ontology (GO) terms; and WGCNA recovered KEGG Lysosome in the brown module. Module regression localised most proteomic age signals to the lysosomal degradative-capacity module, whereas the proteasome was unaffected. McNemar testing and GTEx comparison supported a protein-side, post-transcriptional origin. TCIRG1, CTSA and ATP6V0D1 were recurrent hubs. Network proximity computationally prioritised hydroxytyrosol as a lysosomal-degradative-capacity-preferential candidate, and CDOCKER on cathepsin A linked its advantage over tyrosol to an ortho-hydroxyl group forming additional hydrogen bonds. These results support protein-layer-dominant autophagy-lysosome remodelling as a feature of dermal fibroblast ageing and suggest a cell-type-resolved computational route from ageing proteomics to testable dietary candidates.\n\nID: 42587389\nTitle: Distinct Transposable Element Transcript Patterns in Microglia Across Aging and Alzheimer's Disease.\nAbstract: Microglia, the brain's resident immune cells, are transcriptionally diverse and highly dynamic, but during aging and disease they lose their transcriptomic flexibility and adopt a chronically activated state that is associated with neuroinflammation and pathology. An emerging transcriptomic process that is also increasingly implicated in brain aging, neuroinflammation, and disease is the dysregulation of transposable elements (TEs), repetitive genomic sequences with the potential to cause cellular stress/dysfunction. However, there are limited data on microglial TE transcript patterns in these contexts. Here, we analyzed multiple RNA-seq datasets from isolated human and mouse microglia across aging, Alzheimer's disease (AD), and AD-associated pathology. In contrast to previous observations based on whole-brain tissue and other brain cell types, we found that microglial TE transcript levels remained relatively consistent throughout most of the human lifespan before increasing in late life. We also found that TE transcript levels in microglia from AD patients showed minimal changes compared to age-matched controls, and in RNA-seq analyses of transgenic AD mouse models we observed pathology-associated TE transcript decreases. Subsequent analyses identified inverse associations between TE transcript levels and autophagy/lysosome-related gene expression, and in\u00a0vitro studies suggested that aging- and AD-relevant stimuli, as well as pharmacological autophagy inhibition, modulate TE transcript expression in cultured human microglia. Together, these data provide novel insight into TE transcript dynamics in microglia, highlighting TE transcript patterns that differ from those observed in whole-brain samples and other cell types in aging and AD.\n\nID: 42586252\nTitle: ERLAD-hERG axis and L-type calcium channel activation mediate cholesterol-induced acquired long QT syndrome-related cardiotoxicity.\nAbstract: High cholesterol is a key cardiovascular risk factor that can modulate cardiac electrophysiology and promote acquired long QT syndrome (acLQTS)-related cardiotoxicity, a potentially life-threatening condition associated with QT prolongation, torsade de pointes, and sudden cardiac death. This study investigated the effects of cholesterol overload on human Ether-\u00e0-go-go-Related Gene (hERG/Kv11.1; encoded by KCNH2) potassium channels and L-type calcium channels (LTCC; mainly Cav1.2/CACNA1C in cardiomyocytes), as well as the underlying mechanisms of acLQTS-related cardiotoxicity, using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), whole-cell patch clamp, quantitative real-time PCR (qRT-PCR), Western blotting, immunoprecipitation, fluorescence imaging, and a high-cholesterol diet guinea pig model with rosuvastatin intervention combined with optical mapping. The results showed that transient cholesterol exposure inhibited hERG tail current amplitude and accelerated channel inactivation, with the effect showing a Y652-dependent component, while also enhancing LTCC activity. Mechanistically, cholesterol overload triggered endoplasmic reticulum (ER) stress, impaired hERG proteostasis, and promoted ER-to-lysosome-associated degradation (ERLAD) of hERG. This process was associated with CANX-mediated recognition of abnormal hERG and FAM134B-LC3B-related autophagic-lysosomal processing, contributing to reduced total hERG expression and membrane-localized mature hERG. FAM134B overexpression partially preserved hERG expression and attenuated cholesterol-induced ER stress/autophagy-related abnormalities. In vivo, rosuvastatin improved lipid profiles and cardiac remodeling in high-cholesterol guinea pigs but was associated with more pronounced action potential duration (APD) and QT interval prolongation under high-cholesterol conditions. These findings suggest that cholesterol overload may increase susceptibility to hERG-related repolarization abnormalities during rosuvastatin exposure and highlight the importance of cholesterol management and electrocardiographic (ECG) monitoring in hypercholesterolemic settings.\n\nID: 42578565\nTitle: HDL-associated proteins affecting CVD and systemic inflammation.\nAbstract: It has become clear that elevated HDL-C is not a reliable marker of protection against inflammation and cardiovascular disease (CVD). This review summarizes recent advances in understanding how HDL function is affected by its associated proteins, demonstrating that this is a more appropriate lens through which to assess HDL's protective capacity. Recent publications have demonstrated an inverse relationship between ApoM and clinical outcomes in chronic kidney disease and its concomitant cardiovascular indications. Mechanistic studies show that ApoM's regulation of mitochondrial function and autophagy are likely contributors to this effect. Additionally, ApoA-I, serum amyloid albumin (SAA), and SR-B1 have recently been highlighted as key regulators of atherogenesis through their ability to prevent LDL transcytosis and arterial entrapment by proteoglycans. Lastly, a novel mechanism is described wherein HDL-bound endotoxin is degraded through the endosome-lysosome pathway in an SR-B1-dependent manner, attenuating IL-1\u03b2 activation. In the same study, inhibition of CETP (cholesterol ester transfer protein) increased HDL and improved mortality in a mouse model of sepsis, highlighting this pathway's importance and therapeutic potential of CETP inhibition, which is currently in key clinical trials. HDL regulates inflammation and CVD through a variety of mechanisms independent of reverse cholesterol transport, including autophagy, LDL deposition, endotoxin clearance.\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.

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.

However, whether GCGR directly confers renoprotection and the underlying mechanisms remain unclear. Here, using tubule-specific GCGR loss- and gain-of-function mouse models and human kidney samples, we show that tubular GCGR signaling exerts an important renoprotective role in DKD. Tubular GCGR expression is reduced in humans and mice with DKD and correlates with worse kidney function and increased renal injury. Genetic ablation of tubular GCGR markedly exacerbates DKD and induces pronounced phospholipid accumulation within enlarged lysosomes. Mechanistically, GCGR loss disrupts its association with the V-ATPase V1A subunit ATP6V1A, compromises V1-V0 assembly, and thereby impairs lysosomal acidification. This defect leads to impaired phospholipid hydrolysis and protease maturation, blockade of autophagic flux, and ultimately tubular cell injury. In vivo, ATP6V1A overexpression markedly reverses GCGR deficiency-induced lysosomal dysfunction and DKD progression. Consistently, re-expression of tubular GCGR via AAV9 restores lysosomal function, reduces phospholipid accumulation, and mitigates renal injury in DKD. Together, these findings provide genetic evidence for the renoprotective role of tubular GCGR in DKD, delineate a kidney-intrinsic GCGR-ATP6V1A-lysosome axis that protects tubular integrity, and extend prior GCGR-in-kidney observations into a more concrete GCGR-lysosome mechanism.\n  --- END ACTUAL ABSTRACT FOR 42555719 ---\n\n- ERROR: You cited ID: 42458926 for the quote: \"AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4.\"\n  FACT: Strict Misquote Detected!

Hypobaric hypoxia at high altitudes accelerates aging, while D-galactose (D-gal) injection mimics metabolic aging. The gut microbiota is a key regulator of aging, but whether indigenous probiotics from the high plateaus of Tibet exert comparable or differential efficacy against distinct aging etiologies remains unclear. In this study, we systematically evaluated the protective effects of Lactiplantibacillus plantarum AL4510, a novel probiotic strain isolated from traditional fermented goat milk on the Qinghai-Tibet Plateau. We used both D-gal-induced and hypobaric hypoxia-induced aging models established simultaneously within the same experimental system. AL4510 significantly alleviated oxidative stress in both models, as evidenced by restored serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reduced malondialdehyde (MDA) levels. Systemic inflammation was attenuated, with lower interleukin-1\u03b2 (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1) concentrations. Cellular senescence, assessed using senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) and p16 immunofluorescence, was markedly reduced in both liver and colon tissues by approximately 50-60%. The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovibrio, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculum, and Lactobacillus. Metabolomic profiling revealed that AL4510 replenished short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate in both models, indicating restoration of gut fermentative capacity. Importantly, AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4; in the hypoxia model, it upregulated neuroprotective catalpol, lupeol, and energy-related calcium pantothenate. Integrative correlation and co-occurrence network analyses suggested that AL4510 was associated with a beneficial microbial consortium that correlated with host metabolism potentially involving the microbiota-SCFA axis. Collectively, these findings suggest that AL4510 exerts broad spectrum anti-aging effects potentially involving a \"dual-track\" mechanism: convergent restoration of gut ecological balance and divergent, stress-adapted reprogramming of host metabolism. This study provides a scientific basis for developing AL4510 as a functional probiotic ingredient or postbiotic formulation for high-altitude adaptation, metabolic anti-aging interventions, and gut-targeted nutritional strategies.\n  --- END ACTUAL ABSTRACT FOR 42458926 ---\n\n- ERROR: You cited ID: 42406105 for the quote: \"AGM alleviated sepsis-induced intestinal injury via the PTS-I2R axis by promoting mitophagy and autophagic flux to inhibit IEC apoptosis.\"\n  FACT: Strict Misquote Detected!

This study aimed to elucidate the protective effect of agmatine (AGM) on sepsis-induced intestinal injury and its mitochondrial-targeted antiapoptotic mechanism in intestinal epithelial cells (IECs). We verified the transport and subcellular localization of AGM in IECs via fluorescence assays and established in vitro and in vivo IEC apoptosis models. Functional evaluations using cell viability assays, laser confocal imaging, flow cytometry, transmission electron microscopy, and multiomics techniques were performed. AGM attenuated sepsis-induced intestinal injury, as evidenced by its ability to lower the serum levels of intestinal damage markers in septic mice, attenuate inflammatory factor production and pathological damage in the intestine, and reduce IEC apoptosis. AGM entered IECs via the polyamine transport system (PTS), but not the NMDA receptor, and inhibited IEC apoptosis induced by TNF\u03b1/CHX or TNF\u03b1/ActD. Notably, AGM exerted its antiapoptotic effect by targeting the mitochondrial imidazoline I2 receptor (I2R). Mechanistically, AGM induced mitophagy by decreasing the mitochondrial membrane potential without altering mitochondrial number or function, as ROS production, calcium ion influx, ATP generation, and oxygen consumption were unchanged. AGM also increased autophagic flux, as confirmed upon treatment with various autophagy inhibitors. AGM alleviates sepsis-induced intestinal injury via the PTS-I2R axis by promoting mitophagy and autophagic flux to inhibit IEC apoptosis, laying a foundation for the use of AGM as a potential nutritional supplement or therapeutic agent for sepsis-induced intestinal injury.\n  --- END ACTUAL ABSTRACT FOR 42406105 ---\n\n- ERROR: You cited ID: 42281177 for the quote: \"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.\"\n  FACT: Strict Misquote Detected!

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  --- END ACTUAL ABSTRACT FOR 42281177 ---\n\n- ERROR: You cited ID: 42458574 for the quote: \"ATP6V1A overexpression markedly reverses GCGR deficiency-induced lysosomal dysfunction and DKD progression.\"\n  FACT: Quote was found in context but NOT in the specific abstract mapped to ID '42458574'.\n  \n  Below is the complete, true text of ID 42458574 that you MUST read. \n  Find a valid, verbatim, character-perfect sentence inside this exact block to cite instead, or change your claim to align with what this text actually says:\n  \n  --- BEGIN ACTUAL ABSTRACT FOR 42458574 ---\n  ID: 42458574\nTitle: V-ATPase-targeted siRNA library screening reveals ATP6V1A negatively regulates UVB-induced keratinocyte senescence.\nAbstract: Photoaging is a form of premature skin aging mainly induced by long-term exposure to ultraviolet exposure. Lysosomes are key organelles responsible for the degradation and recycling of intracellular components and are essential for maintaining metabolic and nutrient homeostasis. Although lysosomal dysfunction is closely associated with cellular aging, the role of V-ATPase in regulating lysosomal function during photoaging remains incompletely understood. By screening a V-ATPase-targeted siRNA library and validating the results using publicly available single-cell transcriptomic datasets, we identified ATP6V1A as a key regulator of UVB-induced cellular senescence. Furthermore, ATP6V1A knockdown exacerbated the UVB-induced cellular senescence and impaired lysosomal acidification and membrane integrity, whereas ATP6V1A overexpression effectively alleviated keratinocyte senescence, lysosomal dysfunction and autophagy inhibition. Moreover, treatment with the V-ATPase inhibitor BafA1 aggregated cellular senescence phenotype and autophagy inhibition and this phenomenon partially reversed by ATP6V1A overexpression. Collectively, ATP6V1A promotes autophagy by regulating lysosomal function, thereby relieving UVB-induced cellular senescence.\n  --- END ACTUAL ABSTRACT FOR 42458574 ---\n\n- ERROR: You cited ID: 42225652 for the quote: \"Additionally, metabolic interventions such as caloric restriction mimetics (e.g., spermidine, \u03b1-ketoglutarate, ergothioneine) enhance mitochondrial function, activate autophagy, and reprogram energy metabolism.\"\n  FACT: Strict Misquote Detected!

Therapeutic strategies targeting aging hallmarks can delay aging and mitigate disease risk. Emerging interventions focus on modulating core aging mechanisms, including cellular senescence, metabolic dysfunction, epigenetic alterations, and mitochondrial impairment, etc. Recent advances have focused on three strategies: senolytics (eliminating senescent cells, e.g., dasatinib + quercetin), senomorphics (inhibiting the senescence-associated secretory phenotype, e.g., rapamycin), and senoreversion (rejuvenating senescent cells via epigenetic reprogramming). Additionally, metabolic interventions such as caloric restriction mimetics (e.g., spermidine, \u03b1-ketoglutarate, ergothioneine) enhance mitochondrial function, activate autophagy, and reprogram energy metabolism, demonstrating lifespan extension and healthspan improvement in preclinical models. Collectively, these approaches hold promise for delaying aging and alleviating age-related pathologies, facilitating the transition to precision longevity medicine. Concurrently, artificial intelligence (AI) accelerates discovery by integrating multiomics data, predicting candidate compounds, identifying biomarkers, and enabling personalized interventions. Despite advancements, challenges remain in target specificity, off-target effects, and clinical translation. The convergence of AI, multitarget strategies, and precision medicine signals a transformative era in extending healthspan and combating aging-associated diseases.

Emerging evidence suggests that intracellular zinc dynamics regulate lysosomal function by modulating processes such as acidification and lysosomal biogenesis. We previously identified 1H10 as an AMP-activated protein kinase (AMPK) inhibitor and subsequently demonstrated its zinc-binding capacity and ability to regulate intracellular zinc homeostasis. Building on our prior findings that intra-lysosomal zinc promotes acidification and activates transcription factor EB (TFEB), we investigated whether 1H10 enhances lysosomal function through zinc mobilization in neurons, thereby improving autophagy and reducing pathological protein accumulation. In primary cortical neurons, 1H10 increased lysosomal abundance and enhanced lysosomal degradative capacity in a zinc-dependent manner, as demonstrated by increased cathepsin B activity and DQ-BSA degradation. It alleviated lysosomal dysfunction induced by v-ATPase inhibition and promoted autophagic flux, leading to reduced accumulation of amyloid-\u03b2 (A\u03b2) and tau in neuronal models. In 5XFAD mice, 1H10 treatment showed trends toward improved spatial learning in the Morris water maze, reduced tau phosphorylation at Thr205 and Ser214, normalized LC3-II levels, and restored autophagic-lysosomal homeostasis, without significant changes in extracellular amyloid plaque burden. These findings indicate that zinc-mediated lysosomal activation by 1H10 enhances the autophagy-lysosomal pathway and attenuates tau pathology in AD models, suggesting that targeting lysosomal function may represent a potential therapeutic strategy for neurodegenerative disorders characterized by impaired proteostasis.\n  --- END ACTUAL ABSTRACT FOR 42415176 ---\n\n- ERROR: You cited ID: 42299014 for the quote: \"Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance.\"\n  FACT: Strict Misquote Detected!

Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS.\n  --- END ACTUAL ABSTRACT FOR 42299014 ---\n\n- ERROR: You cited ID: 42529163 for the quote: \"Disruption of this axis can impair endosomal maturation, lysosomal acidification, autophagic degradation, and lysosome-centered signaling pathways, resulting in defective cellular clearance.\"\n  FACT: Strict Misquote Detected!

Its dynamic function is closely intertwined with lipid metabolism, forming an integrated regulatory network termed the endo-lysosomal-lipid axis. Disruption of this axis can impair endosomal maturation, lysosomal acidification, autophagic degradation, and lysosome-centered signaling pathways, resulting in defective cellular clearance and chronic inflammatory responses. Conversely, dysfunction of the endo-lysosomal system disrupts cholesterol trafficking, lipid redistribution, and macromolecular degradation, ultimately promoting secondary lipid accumulation and metabolic imbalance. In this review, we summarize the reciprocal interactions between lipid metabolism and endo-lysosomal function, with particular emphasis on membrane trafficking, lysosomal homeostasis, autophagy, membrane contact sites, and multicellular lipid clearance networks. We further discuss how these interconnected processes contribute to disease progression and highlight emerging therapeutic strategies aimed at restoring lysosomal function and lipid homeostasis. Understanding the dynamic regulation of the endo-lysosomal-lipid axis may provide new mechanistic insights into metabolic and neurodegenerative disorders and identify novel therapeutic opportunities.\n  --- END ACTUAL ABSTRACT FOR 42529163 ---\n\n- ERROR: You cited ID: 42598912 for the quote: \"Our findings establish a live-cell platform for analysing autophagy in NMR cells and identify a distinctive, reversible vacuolation response to lysosomal stress.\"\n  FACT: Strict Misquote Detected!

However, most studies in NMR cells have relied on static biochemical or ultrastructural readouts, leaving the dynamic organisation of autophagy in living cells poorly defined. Here, we establish a stable tandem fluorescent autophagy reporter in NMR skin fibroblasts using an mCherry-EGFP-LC3NMR construct to enable live-cell, single-cell resolution analysis of ALP dynamics. Under basal conditions, NMR skin fibroblasts exhibit a greater abundance of LC3-positive structures than HeLa cells, together with a mixed population of autophagosomes and autolysosomes, indicating a distinct steady-state organisation of the ALP. Chloroquine (CQ)-induced lysosomal stress caused the expected accumulation of LC3-positive structures but also triggered the formation of large cytoplasmic vacuoles in NMR skin fibroblasts. Importantly, this vacuolation was not associated with acute cytotoxicity and progressively resolved following CQ removal, accompanied by reorganisation of LC3-positive compartments and recovery of lysosomal acidity. Electron microscopy showed that CQ-induced vacuoles are membrane-bound, containing internal material and co-existing with multiple ALP-related vesicular compartments. Primary NMR skin fibroblasts display a similar vacuolation phenotype, indicating that this response is not an artefact of immortalisation or reporter expression. Together, these findings establish a live-cell platform for analysing autophagy in NMR cells and identify a distinctive, reversible vacuolation response to lysosomal stress, consistent with dynamic remodelling of the lysosomal system within NMR skin fibroblasts.\n  --- END ACTUAL ABSTRACT FOR 42598912 ---\n\n- ERROR: You cited ID: 42400323 for the quote: \"PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification.\"\n  FACT: Strict Misquote Detected!

However, disease-modifying therapies targeting this pathway remain unavailable. Here, we generated induced pluripotent stem cells (iPSCs) from a PARK9 patient carrying an ATP13A2 mutation and established mutation-corrected isogenic control iPSCs. PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification, reduced mature cathepsin D levels, CD63-positive vesicle accumulation, LC3B-positive autophagosome accumulation, cytoplasmic pSer129 \u03b1-synuclein accumulation, and increased cleaved caspase-3 signals. These phenotypes were ameliorated in mutation-corrected neurons, supporting the contribution of ATP13A2 dysfunction to these abnormalities. We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation. Among these, paroxetine, Ro 25-6981, amisulpride, and PK11195 showed additional, compound-dependent effects on PARK9-associated phenotypes, including lysosomal acidification, CD63-positive vesicle accumulation, cytoplasmic pSer129 \u03b1-synuclein signals, and cleaved caspase-3 signals. These findings establish PARK9 iPSC-derived neurons as a useful model of lysosomal dysfunction-associated PD pathology and provide a practical screening platform for identifying candidate compounds that modulate autophagy-lysosome pathway-related cellular phenotypes.\n  --- END ACTUAL ABSTRACT FOR 42400323 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Spermidine, a dietary polyamine from

The clinical course varies widely. Limb weakness, bulbar impairment, respiratory decline, fine-motor dysfunction, cognitive change, mood symptoms, and fatigue may each appear at different times and progress at different rates. This variability suggests that motor neuron loss alone may not fully explain the patient-level pattern of symptoms. This article is a narrative hypothesis framework, not a clinical guideline or a validated stratification tool. Established ALS biology, associative genomic findings, preclinical observations, computational predictions, and author-derived hypotheses are therefore separated throughout the article. This review brings together four interlinked studies by the current author as a primary hypothesis-generating corpus, which proposes that synaptic plasticity fragility may initiate a microglial pruning continuum shared by major depressive disorder and ALS, while ALS-specific progression may depend on mitochondrial stress, oxidized nicotinamide adenine dinucleotide (NAD+) compensation failure, and collapse of autophagy under aging-related limits. The model presented here maps symptom domains to vulnerable circuit compartments and separates three broad biological states: compensated plasticity, fragile plasticity, and network collapse. A compact mechanistic formulation is used to describe the balance between pruning pressure, glutamatergic burden, and aging stress on one side, and oxidative phosphorylation capacity, NAD+ reserve, and autophagic clearance on the other. The framework also incorporates opposing phosphoinositide 3-kinase (PI3K)/AKT/mechanistic target of rapamycin (mTOR) and peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1\u03b1) pathway patterns that may distinguish ALS from frontotemporal dementia (FTD) within an aging context. The result is a falsifiable, biomarker-oriented hypothesis model for future studies, not an evidence-based diagnostic or therapeutic algorithm.\n  --- END ACTUAL ABSTRACT FOR 42164014 ---\n\n\n\u2705

The dataset confirms that spermidine induces autophagy via EP300 inhibition and other mechanisms, and that TMEM175 dysregulation contributes to neurodegenerative pathogenesis, yet the two are not explicitly linked in the current corpus.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis of geroprotective polyamines and lysosomal ion channel regulation indicates that while both systems are critical for maintaining proteostasis, the specific regulatory axis connecting spermidine-driven autophagy to TMEM175-mediated lysosomal acidification in C9orf72-ALS/FTD pathology remains an unverified, albeit mechanistically sound, cross-talk intersection.\n\n### [INTRODUCTION & JUSTIFICATION]\nLysosomal dysfunction is recognized as a fundamental driver of neurodegenerative pathology. Spermidine, a dietary polyamine, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Autophagic pathways, including those maintained by the C9orf72/SMCR8 complex, are vital for microglial homeostasis and lysosomal repair. Simultaneously, TMEM175 serves as a lysosomal cation channel essential for maintaining lysosomal pH and function. Dysregulation of the autophagy-lysosomal pathway is a converging mechanism of pathology in C9orf72-associated diseases. While evidence indicates that pharmacological activation of autophagy can mitigate DPR accumulation and proteostatic stress in C9orf72 models, a direct regulatory relationship between spermidine and the TMEM175 channel remains a high-potential hypothesis for future investigation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   TMEM175 activity can be synergistically modulated, suggesting complex channel gating that might be responsive to metabolic states influenced by polyamines.\n*   The C9orf72/SMCR8 complex maintains microglial homeostasis via RAB8A-ESCRT-mediated lysosomal repair, providing a structural repair mechanism distinct from, yet likely coordinated with, macroautophagy.\n*   Lysosomal membrane damage acts as a specific trigger for ATG8-conjugation, indicating that membrane integrity and ionic flux are tightly coupled through the endo-lysosomal-lipid axis.\n*   The same galectin axis can amplify neuroinflammation and proteopathic spread in some settings yet support recovery or tissue protection in others, highlighting the context-dependency of lysosomal quality control.\n*   Protein-layer-dominant autophagy-lysosome remodelling is a feature of dermal fibroblast ageing, suggesting that post-transcriptional control of lysosomal capacity may precede transcriptional changes in systemic aging.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Over the past decade, a rapidly expanding literature has identified galectins as regulators of microglial activation, misfolded protein pathology, vesicle damage sensing, autophagy, synaptic plasticity, myelination, vascular repair, and neuroimmune communication. Galectins operate across intracellular and extracellular compartments to integrate cellular stress and innate immune signaling. Here, we review CNS studies of galectin-1, galectin-3, galectin-4, galectin-8, and galectin-9, focusing primarily on work published from 2019 onward while incorporating selected earlier studies to establish foundational concepts. Across experimental models and human studies, galectins orchestrate microglial state transitions, regulate aggregation and propagation of amyloid-\u03b2, tau, \u03b1-synuclein, and mutant huntingtin, and function as intracellular sensors of vesicle and lysosomal damage. Multiple studies further establish galectins as biomarkers and therapeutic targets across Alzheimer's disease, Parkinson's disease, Huntington's disease, multiple sclerosis, stroke, traumatic brain injury, spinal cord injury, retinal degeneration, and chronic pain. Importantly, this review highlights a stage- and context-dependent paradox in which the same galectin axis can amplify neuroinflammation and proteopathic spread in some settings yet support recovery or tissue protection in others. Together, these findings position galectins as central regulators that convert intracellular stress into coordinated neuroimmune programs shaping proteinopathy, circuit dysfunction, and tissue remodeling.",

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

Gene expression analysis of the spinal cord and gastrocnemius of the SOD1-G93A ALS mouse model revealed a strong increase in inflammatory pathways and, specifically in the ALS gastrocnemius, a decrease in mitochondrial transcription and an increase in ribosomal protein expression. Treatment of ALS mice with the polyamine spermidine (SPD), a promising molecule in combating neurodegeneration and muscle atrophy, is able to partially restore the expression of more than four thousand genes in gastrocnemius tissue, including the mitochondrial regulator Pgc1\u03b1, as well as all the mitochondrial encoded genes and a large class of ribosomal proteins. SPD enhanced mitochondrial bioenergetics, as evidenced by Seahorse experiments, and delayed muscle weakness in vivo, as shown by grip strength records. These findings suggest that SPD can act as a potential supplement in the therapeutic strategy for ALS, offering a foundation for further research to improve patient outcomes.",
        "42092406": "ID: 42092406\nTitle: TRIM16 attenuates TDP43-mediated oxidative injury by coordinating Nrf2 activation and TFR1 autophagic degradation.\nAbstract: TAR DNA-binding protein 43 (TDP43) aggregation is a well-established pathological hallmark of amyotrophic lateral sclerosis (ALS) and related neurodegenerative disorders, contributing significantly to oxidative stress and neuronal injury. Here, we report that the M337V mutation in TDP43 exacerbates its proteotoxicity relative to the wild-type protein. Concurrently, multi-omics analysis revealed a pronounced downregulation of TRIM16 in motor neuron-like cells expressing either wild-type or M337V mutant TDP43. Functional studies demonstrated that TRIM16 overexpression effectively mitigated oxidative stress, restored mitochondrial integrity, and suppressed ferroptosis. Mechanistically, TRIM16 promoted the ubiquitination and degradation of Keap1, thereby facilitating the activation of Nrf2-mediated antioxidant genes. Furthermore, we identified the iron import receptor TFR1 as a novel ubiquitination substrate of TRIM16. TRIM16 mediated the ubiquitination of TFR1 and targeted it for p62-dependent autophagic degradation, which in turn reduced iron accumulation and lipid peroxidation. Collectively, our findings establish TRIM16 as a pivotal suppressor of TDP43-induced toxicity by orchestrating dual cytoprotective pathways to enhance cellular resilience, highlighting its promising therapeutic potential for TDP43 proteinopathy.",
        "42097046": "ID: 42097046\nTitle: BAG3V468M impairs proteasomal protein clearance and induces dilated cardiomyopathy in vivo.\nAbstract: Idiopathic dilated cardiomyopathy (DCM) is one of the major causes of heart failure, characterized by left ventricular dilation and systolic dysfunction in the absence of an identifiable cause, and is associated with reduced life expectancy. Genetic studies, including genome-wide association studies, have identified variants in BAG3, a key regulator of protein quality control (PQC), as contributors to both familial and sporadic forms of DCM. Impaired PQC and the accumulation of misfolded proteins (proteinopathy) have emerged as potential pathogenic mechanisms. Here, we investigated the molecular consequences of a recently identified BAG3 missense variant (V468\u202fM) associated with familial DCM. To assess the in vivo effects of the variant, human BAG3V468M was ectopically expressed in wild-type zebrafish embryos. Overexpression of BAG3V468M resulted in a DCM-like phenotype characterized by ventricular dilation, reduced heart rate, and impaired contractility. Transmission electron microscopy revealed marked disruption of myocardial ultrastructure and sarcomeric organization. To explore the impact on proteostasis, markers of autophagy (LC3-I/II and p62) were analyzed and showed no significant differences between BAG3V468M and control embryos under basal conditions. In contrast, analysis of the ubiquitin-proteasome system demonstrated a significant accumulation of ubiquitinated proteins in BAG3V468M-expressing embryos, suggesting impaired proteasomal protein clearance or increased proteotoxic stress. Expression of BAG3V468M induces a DCM-like phenotype in vivo associated with disrupted myocardial architecture and altered proteostasis. While canonical autophagy markers remain unchanged, the accumulation of ubiquitinated proteins points toward a disturbance in ubiquitin-mediated protein turnover. These findings implicate mutation-specific alterations in proteostasis as a potential mechanism contributing to BAG3-associated cardiomyopathy.",
        "42143042": "ID: 42143042\nTitle: VCP modulation ameliorates pathological features in C9orf72 models.\nAbstract: Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are devastating neurodegenerative diseases linked by similar pathological mechanisms, which, in some familial forms, may be associated with the same genetic alterations. Among them, the most common is the C9ORF72 (C9) mutation. The C9 mutation consists in an aberrant expansion of the hexanucleotide repeat (G4C2)n that leads to the production and accumulation of toxic dipeptide repeat proteins (DPRs). Some of these C9-DPRs contribute to neuronal dysfunction and degeneration through different mechanisms. One of these involves alterations in the protein quality control (PQC) system, specifically in the autophagy-lysosomal pathway. Valosin-containing protein (VCP) is a critical component of the PQC system, assisting the degradation of misfolded proteins and damaged organelles and the maintenance of cellular homeostasis. In this study, we investigated the role of VCP in modulating pathological features associated with C9 mutation. Using neuronal cell models, we demonstrated that VCP overexpression significantly reduced C9-DPRs levels. This reduction is mediated by mechanisms involving both the ubiquitin-proteasome system (UPS) and autophagy. Additionally, we also observed that C9-DPRs induce lysosomal damage, which is counteracted by VCP overexpression, as indicated by decreased galectin-3 puncta and restored lysosomal pH. We then pharmacologically activated VCP-mediated clearance through SMER28, increasing the clearance of the most toxic DPR, the polyPR. We also determined that in this model, SMER28 activity is mediated by the UPS and is associated with the mitigation of DPR-induced lysosome damage. Additionally, using motor neurons derived from induced pluripotent stem cells (iPSC-MNs) from C9-ALS mutation carriers, we demonstrated that SMER28 treatment significantly decreased polyGA levels, a marker for C9-DPR accumulation. Moreover, SMER28 rescued C9-MNs commitment to differentiation and the alteration in the expression of autophagy-related genes. Taken together, our findings strongly support VCP as a modulator of C9 pathology and highlight its potential as a therapeutic target.",

        "42163657": "ID: 42163657\nTitle: Mitochondrial Function in Neurons and Glia in Health and Its Alteration in Parkinson's Disease: A Review.\nAbstract: Mitochondria play an important role in maintaining redox balance, energy, calcium, and the viability of neurons. The mitochondrial dysfunction is one of the primary sources of glial activation and dopaminergic neuron loss in Parkinson's disease (PD). The key biochemical elements of the pathogenesis of PD include impaired oxidative phosphorylation, elevated generation of reactive oxygen species (ROS), and impaired mitophagy. This review is a synthesis and stringent evaluation of recent experimental, clinical and genetic studies relating mitochondrial dysfunction and Parkinson's disease (PD). We examined information on bioenergetics, mitochondrial dynamics, calcium homeostasis, and interactions between neurons and glia. The molecular and therapeutic importance of therapies, such as mitophagy modulators, bioenergetic enhancers, and mitochondrial antioxidants, was investigated. The absence of Complex I, excess ROS, mitochondrial DNA damage, and nonfunctioning fusionfission cycles leads to neurodegeneration. The glial metabolic abnormalities worsen the oxidative stress and neuroinflammation, weakening the support of the neurons. The effects of impaired mitophagy are the accumulation of dysfunctional mitochondria, and the effects of calcium overload disrupt energy metabolism. Neuroprotective effects of such substances as spermidine, urolithin A, resveratrol, \u03b1lipoic acid, MitoQ, SkQ1, or CoQ10 have been shown using preclinical research. Sacrifices such as exercising and proper dieting enable the mitochondria to perform better and become stronger. Mitochondrial dysfunction enhances the progression of PD through oxidative stress, bioenergetic breakdown, and inflammatory signalling. Attention to these related systems is an entire way to alter the direction of a disease. PD can be treated using an increase in mitochondrial quality control, redox regulation, and metabolic efficiency. Continued studies in the framework of precision medicine are required to validate the safety and effectiveness of mitochondrial-targeted medications.",
        "42164014": "ID: 42164014\nTitle: Symptom-Level Precision Neurology in Amyotrophic Lateral Sclerosis (ALS): Linking Microglial Pruning, Mitochondrial Nicotinamide Adenine Dinucleotide (NAD+) Compensation, and Autophagy Failure Across the Aging Spectrum.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a heterogeneous neurological disease with limited disease-modifying treatment options and, for many patients, a short survival window. The clinical course varies widely. Limb weakness, bulbar impairment, respiratory decline, fine-motor dysfunction, cognitive change, mood symptoms, and fatigue may each appear at different times and progress at different rates. This variability suggests that motor neuron loss alone may not fully explain the patient-level pattern of symptoms. This article is a narrative hypothesis framework, not a clinical guideline or a validated stratification tool. Established ALS biology, associative genomic findings, preclinical observations, computational predictions, and author-derived hypotheses are therefore separated throughout the article. This review brings together four interlinked studies by the current author as a primary hypothesis-generating corpus, which proposes that synaptic plasticity fragility may initiate a microglial pruning continuum shared by major depressive disorder and ALS, while ALS-specific progression may depend on mitochondrial stress, oxidized nicotinamide adenine dinucleotide (NAD+) compensation failure, and collapse of autophagy under aging-related limits. The model presented here maps symptom domains to vulnerable circuit compartments and separates three broad biological states: compensated plasticity, fragile plasticity, and network collapse. A compact mechanistic formulation is used to describe the balance between pruning pressure, glutamatergic burden, and aging stress on one side, and oxidative phosphorylation capacity, NAD+ reserve, and autophagic clearance on the other. The framework also incorporates opposing phosphoinositide 3-kinase (PI3K)/AKT/mechanistic target of rapamycin (mTOR) and peroxisome proliferator-activated receptor-gamma coactivator-1alpha (PGC-1\u03b1) pathway patterns that may distinguish ALS from frontotemporal dementia (FTD) within an aging context. The result is a falsifiable, biomarker-oriented hypothesis model for future studies, not an evidence-based diagnostic or therapeutic algorithm.",
        "42167675": "ID: 42167675\nTitle: TDP-43: a critical amplifier of Alzheimer's disease beyond amyloid and tau.\nAbstract: TAR DNA-binding protein 43 (TDP-43) proteinopathy has recently emerged as a pivotal, yet underrecognized, contributor to the multifaceted neuropathology of Alzheimer's disease (AD). While amyloid-\u03b2 and tau have long been established as cardinal pathological hallmarks, growing evidence delineates TDP-43 as a critical participant of neurodegeneration, intricately interwoven with amyloid and tau pathologies. TDP-43 mislocalization, post-translational modifications, and aggregation potentiate neuronal loss through disruption of RNA metabolism, nucleocytoplasmic transport, and protein homeostasis. This tripartite interplay manifests in synergistic and possibly multidirectional pathological cascades that amplify neuronal vulnerability and cognitive decline, thereby complicating the clinical and pathological complexity of AD. Here, we critically reviewed the mechanistic crosstalk among TDP-43, amyloid-\u03b2, and tau, focusing on preclinical and clinical evidence, highlighting possible convergent pathways of aggregation, propagation, and neurodegeneration. Moreover, this review also evaluates mitochondrial dysfunction, autophagy failure, and inflammation as underlying events associated with TDP-43 pathology. Therefore, we argue for a reconceptualization of AD as a dynamic proteinopathy network, with TDP-43 as a core integrative node influencing disease onset and its progression. Notably, we discuss emerging diagnostic modalities associated with molecular tracers of TDP-43, providing prospects for future biomarker identification. Finally, this review articulates the translational relevance of TDP-43 therapy in AD and related neurological disorders, emphasizing the necessity of holistic approaches that transcend the traditional amyloid-tau paradigm to effectively tackle the full spectrum of AD pathobiology.",
        "42215790": "ID: 42215790\nTitle: The C9orf72/SMCR8 complex maintains microglial homeostasis via RAB8A-ESCRT-mediated lysosomal repair.\nAbstract: Microglia are critical regulators of neuroinflammation and neurodegeneration. Haploinsufficiency of C9orf72, the most frequently mutated gene in\u00a0amyotrophic lateral sclerosis and frontotemporal dementia, has been linked to autophagy-lysosomal pathway defects, but the role\u00a0of C9orf72 in microglia remains unclear. Here, we identify the C9orf72/SMCR8 complex as a key regulator of microglial homeostasis through promoting lysosomal membrane repair. Loss of C9orf72 and SMCR8 in mice causes age\u2011dependent neuroinflammation and microgliosis, with microglia adopting a disease-associated state. In aged brain and spinal cord tissue, microglia display lysosomal damage marked by galectin\u20113 accumulation. Using a lysosomotropic agent to induce lysosomal damage in microglia, we find that C9orf72/SMCR8-deficient cells accumulate damaged lysosomes and show defective recruitment of phosphorylated RAB8A and the Endosomal Sorting Complexes Required for Transport (ESCRT) machinery\u00a0to damaged lysosomes. Notably, mutant microglia accumulate GTP\u2011bound RAB8A, which becomes hyperphosphorylated and mislocalized to RAB7-positive, LAMP1-negative vesicles. The GTPase-activating activity of the C9orf72/SMCR8 complex is essential for lysosomal repair. Our findings reveal that the C9orf72/SMCR8 complex coordinates RAB8A-ESCRT-mediated lysosomal repair to safeguard microglial homeostasis and limit neuroinflammation.",
        "42222188": "ID: 42222188\nTitle: Dietary pyrroloquinoline quinone and spermidine in healthy longevity: targeting the hallmarks of aging.\nAbstract: Aging is a multifaceted biological process driven by interconnected cellular and molecular hallmarks. As geroscience increasingly prioritizes healthspan over lifespan, nutritional interventions targeting multiple aging mechanisms have gained attention as accessible strategies to mitigate age-related functional decline. This mini review synthesizes recent evidence on how the bioactivities of two food-derived geroprotective compounds, pyrroloquinoline quinone (PQQ) and spermidine (SPD), intersect with the hallmarks of aging and their distinct and overlapping roles in maintaining cellular homeostasis. PQQ primarily functions as a mitochondrial and redox regulator, enhancing mitochondrial biogenesis and bioenergetic capacity through the AMP-activated protein kinase (AMPK) and sirtuin1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator 1-alpha pathways. In contrast, SPD acts as a key regulator of cellular quality control by inducing macroautophagy and preserving proteostasis, largely through modulation of histone and autophagy-related protein acetylation. These complementary mechanisms converge on several key hallmarks of aging, including genomic instability, deregulated nutrient sensing, mitochondrial dysfunction, and chronic inflammation. The anti-aging mechanisms of PQQ and SPD originate from distinct upstream biochemical processes but converge on shared signaling hubs, including the AMPK/SIRT1 axis and autophagy-related networks. This convergence suggests a coordinated network-level complementarity that may offer a more robust intervention against age-related decline than targeting independent pathways alone.",
        "42225652": "ID: 42225652\nTitle: Insights into the therapeutic strategies for aging and aging-associated diseases.\nAbstract: Aging is a complex biological process characterized by progressive functional decline, driving the incidence of age-related diseases such as neurodegeneration, metabolic disorders, and cardiovascular diseases. Therapeutic strategies targeting aging hallmarks can delay aging and mitigate disease risk. Emerging interventions focus on modulating core aging mechanisms, including cellular senescence, metabolic dysfunction, epigenetic alterations, and mitochondrial impairment, etc. Recent advances have focused on three strategies: senolytics (eliminating senescent cells, e.g., dasatinib + quercetin), senomorphics (inhibiting the senescence-associated secretory phenotype, e.g., rapamycin), and senoreversion (rejuvenating senescent cells via epigenetic reprogramming). Additionally, metabolic interventions such as caloric restriction mimetics (e.g., spermidine, \u03b1-ketoglutarate, ergothioneine) enhance mitochondrial function, activate autophagy, and reprogram energy metabolism, demonstrating lifespan extension and healthspan improvement in preclinical models. Collectively, these approaches hold promise for delaying aging and alleviating age-related pathologies, facilitating the transition to precision longevity medicine. Concurrently, artificial intelligence (AI) accelerates discovery by integrating multiomics data, predicting candidate compounds, identifying biomarkers, and enabling personalized interventions.

The 'protein-as-pathogen' model, where shed viral proteins act as soluble neurotoxins, is now central to understanding this phenomenon. This review presents the opinion that the most critical recent developments are not that these proteins are toxic, but how their mechanisms converge. We synthesize evidence from the last two years showing that proteins from diverse, highly infectious virus families with zoonotic potential (e.g. Coronaviridae, Flaviviridae, Orthomyxoviridae) engage shared host pathways. We focus on two convergent mechanisms: (1) the activation of glial Toll-like receptor (TLR)4/TLR2 signaling, which initiates a chronic neuroinflammatory cascade, and (2) the disruption of host proteostasis, which seeds neurodegenerative proteinopathies like alpha-synuclein and tau aggregation. This framework positions post-viral syndromes as mechanistically related disorders and identifies pan-viral therapeutic targets, such as TLR inhibitors and autophagy activators.",

The aim of this study was to investigate the functional impact of SCARB2 overexpression on chemotherapy response, reactive oxygen species (ROS) production and proteomic composition of human ovarian adenocarcinoma cells A2780. To induce SCARB2 overexpression, A2780\u202fcells were transfected using a PiggyBac vector system. Two clones with the highest SCARB2 expression (L and V) were selected for further analyses. Differences in chemosensitivity were assessed using the MTS assay. Proteomic analysis was used to identify differentially expressed proteins and enriched pathways. We also performed flow cytometry to investigate changes in ROS production and lysosomal activity. Lysosomal distribution was assessed using LAMP1 immunofluorescence staining followed by confocal microscopy, and total cholesterol levels were determined using an enzymatic colorimetric assay. Both clones showed increased sensitivity to cisplatin compared to the control group. In contrast, clone V showed resistance to doxorubicin and no significant differences were observed for gemcitabine, except for a transient sensitizing effect when low concentrations used. Elevated ROS levels were detected in untreated clones, and after doxorubicin exposition. Proteomic analysis showed significant changes in lysosome-associated proteins, with consistent enrichment of the lysosomal pathway across all experimental comparisons. Immunofluorescence analysis of LAMP1 and LysoTracker staining demonstrated altered lysosomal distribution and activity in SCARB2-overexpressing clones. In addition, both SCARB2-overexpressing clones exhibited significantly reduced total cholesterol levels compared with control cells. This study broadens our understanding of SCARB2 in ovarian cancer. SCARB2 overexpression induces extensive lysosomal reprogramming in A2780 ovarian cancer cells and modulates chemotherapy response.",

Major hallmarks of aging include oxidative stress, chronic neuroinflammation, mitochondrial dysfunction, and impaired proteostasis. Although caloric restriction (CR) has consistently demonstrated neuroprotective effects, its long-term effects in humans remain challenging. Consequently, CRMs such as metformin, spermidine, and curcumin have been widely used because of their ability to recapitulate key molecular effects of CR. Despite their therapeutic effects, the clinical translation of CRMs is significantly limited by their poor bioavailability, rapid metabolism, low aqueous solubility, and inefficient penetration across the blood-brain barrier (BBB). A nanoparticle-based drug delivery system provides a promising approach to address these limitations. Polymeric, liposomal, and lipid-based nanocarriers can be engineered to increase BBB transport via receptor-mediated transcytosis and to enable targeted and sustained drug release. Encapsulation of CRMs within nanoparticles has improved their pharmacokinetic and pharmacodynamic profiles by increasing their stability and bioavailability and reducing systemic degradation. However, targeted delivery of CRMs has been shown to modulate aging-associated pathways, which are necessary for the maintenance of neuronal integrity and synaptic function. This review highlights the potential of CRM-loaded nanocarriers as emerging therapeutic systems to delay brain aging and age-associated disorders. Furthermore, the current challenges and future perspectives on optimizing brain-targeted delivery to enable successful clinical translation in age-related NDDs are discussed.",

Although the genetic basis of limbic-predominant age-related TDP-43 encephalopathy neuropathologic change remains largely unknown, TMEM106B, GRN and APOE loci are frequently implicated. Here, we examined nine previously reported limbic-predominant age-related TDP-43 encephalopathy neuropathologic change risk loci (ARHGEF28, APOE, GRN, KAZN, LHX1, TPCN1, TMEM106B, UNC13C and WWOX) in a population cohort of 262 individuals from the Vantaa 85 + study. We also tested whether Alzheimer's disease polygenic risk score without APOE was associated with limbic-predominant age-related TDP-43 encephalopathy neuropathologic change. Using ordinal logistic regression models, GRN rs5848 (odds ratio = 2.45, 95% confidence interval: 1.71-3.52, adjusted P = 5.75 \u00d7 10-6), APOE \u03b54 dose (odds ratio = 1.73, 95% confidence interval: 1.07-2.80, adjusted P = 0.030) and KAZN rs72643142 (odds ratio = 2.38, 95% confidence interval: 1.38-4.11, adjusted P = 0.0048) were associated with higher limbic-predominant age-related TDP-43 encephalopathy neuropathologic change stage. Additionally, Alzheimer's disease polygenic risk score without APOE was associated with limbic-predominant age-related TDP-43 encephalopathy neuropathologic change after adjusting for age, sex, Alzheimer's disease pathology and APOE \u03b54 dose (odds ratio = 1.36, 95% confidence interval: 1.06-1.75, adjusted P = 0.027).

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.",
        "42282588": "ID: 42282588\nTitle: From anti-fungal to potential neurotherapeutic: Posaconazole as an effective inhibitor of cellular TDP-43 pathology.\nAbstract: Recently, we showed that ketoconazole, a known anti-fungal inhibitor of CYP51, stabilized TAR DNA-binding protein 43 (TDP-43) native self-interactions, reduced TDP-43 pathology and rescued TDP-43-induced SREBP2 downregulation. Despite its promising effects, ketoconazole is not viable for repurposing for ALS due to liver toxicity side effects that occur when orally delivered. To address this, we tested the activities of seven additional known azole-based CYP51 inhibitors in order identify a viable alternative to ketoconazole. Using our established TDP-43 mislocalization and aggregation assay in HEK293T cells, we identified posaconazole, an FDA-approved, CNS-penetrant and orally delivered anti-fungal, as the strongest inhibitor of TDP-43 pathology. Posaconazole was able to reduce insoluble TDP-43 and restore SREBP2 levels, outperforming ketoconazole. Mechanism of action (MOA) experiments suggest posaconazole is able to outperform ketoconazole by inducing a significantly stronger activation of autophagy and upregulation of heat shock proteins known to clear TDP-43. Further MOA experiments show that the effects of posaconazole on TDP-43 are dependent on its known ability to lower cellular cholesterol levels. By correlating our experimental results on the eight CYP51 inhibitors tested, we show that predicted affinity towards human CYP51 strongly correlates with the inhibitors' ability to lower TDP-43 aggregation and mislocalization. Finally, we tested posaconazole in a low dose sodium arsenite ALS model in iPSC-derived motor neurons, showing that it is efficacious at inhibiting TDP-43 pathology in the nanomolar range. Altogether, these results support the repurposing of posaconazole for ALS/FTD as a means to prevent TDP-43 pathology.",

Key pathogenic proteins, including TDP-43, SOD1, FUS, and dipeptide repeat proteins (DPRs) from C9orf72 expansions, drive disease progression through diverse but converging mechanisms. TDP-43 proteinopathy, present in nearly all ALS cases, involves cytoplasmic mislocalization, misfolding, and aggregation, disrupting RNA processing, protein transport, and DNA repair. Similarly, SOD1 and FUS mutations promote toxic protein aggregation, impairing cellular homeostasis and contributing to neuronal dysfunction. C9orf72-derived DPRs exert toxicity by interfering with nucleocytoplasmic transport. The propagation of these pathogenic proteins between neurons and glia, often via prion-like mechanisms, underlies the characteristic spread of ALS pathology throughout the nervous system. Cellular protective responses, such as molecular chaperones and the ubiquitin-proteasome system, attempt to mitigate aggregation but are often overwhelmed in disease states. Mitochondrial dysfunction, oxidative stress, and disturbances in calcium homeostasis are also implicated, with evidence showing that SOD1 mutations can alter redox balance and mitochondrial function in both neurons and non-neuronal cells. Impaired DNA repair mechanisms, involving proteins such as TDP-43, FUS, NEK1, and VCP, have emerged as important contributors to ALS pathogenesis, linking protein aggregation to genomic instability. Recent therapeutic strategies focus on directly targeting misfolded proteins using small molecules, peptides, or antisense oligonucleotides to inhibit aggregation or enhance clearance, offering hope for disease modification. Understanding the interplay between protein aggregation, impaired RNA metabolism, and cellular stress responses is crucial for developing effective translational therapies for ALS.",

This reduced resilience is believed to be underpinned by the hallmarks of ageing, the key biological mechanisms driving the aged phenotype. Geroprotectors are drugs that are proposed to slow down the ageing process and promote longevity and healthspan. Despite this, mechanistic studies in healthy older adults are lacking. This trial will test the hypothesis that geroprotectors targeted towards biological mechanisms associated with poor resilience can reverse these pathways within a three-week period. Three geroprotectors with a good safety profile in older adults and evidence of effect on the hallmarks of ageing will be administered to 60 (30 female; 30 male) adults 70\u2009+\u2009. Participants will be randomised to one of three arms (Metformin MR 1500 mg, Fisetin 100 mg or Spermidine 15 mg). Participants will be extensively clinically characterised at baseline. Blood, abdominal adipose tissue and stool samples will be taken at baseline and following the three-week intervention. The primary research question will answer whether a three-week course of Metformin, Spermidine, or Fisetin reduce the number of senescent cells as measured by SA-\u03b2-GAL in adipose biopsies in healthy older volunteers. Additionally, there will be assessment of the effect of the geroprotectors on other hallmarks of ageing, including autophagy, immunosenescence, chronic inflammation, dysregulated mTOR signalling, epigenetic age, DNA damage, dysregulated metabolism, stem cell exhaustion and microbial composition. Ethical approval is in place (24/LO/0549).

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

Frontotemporal lobar degeneration refers to the pathological changes seen in frontotemporal dementia, characterized by atrophy of the frontal and temporal lobes and the presence of abnormal protein inclusions. In the case of frontotemporal lobar degeneration with hyperphosphorylated TDP-43 positive inclusions (FTLD-TDP), five pathological subtypes (A, B, C, D and E) are observed based on the types and distribution of inclusions found in the brain. In all subtypes, there tends to be a large variability in the number of pathological inclusions observed between cases, with limited correlation to clinical manifestations. TDP-43 is an RNA-binding protein belonging to the heterogeneous nuclear ribonucleoprotein (hnRNP) family, which along with other hnRNPs, modulates multiple aspects of RNA processing. HnRNPs other than TDP-43 have been implicated in several neurological diseases, including Amyotrophic Lateral Sclerosis, FTLD-TDP, frontotemporal lobar degeneration with fused in sarcoma (FTLD-FUS) and Alzheimer's disease. Multiple hnRNPs have been found in pathological inclusions in specific subtypes of FTLD-TDP, suggesting potential roles in the disease process. The role of the hnRNP network in frontotemporal lobar degeneration disease pathogenesis, however, has not yet been investigated. This study aimed to comprehensively evaluate the presence and expression of hnRNP proteins in two pathological subtypes of sporadic FTLD-TDP (A and C) as well as the genetic form FTLD-TDP A C9orf72 using immunohistochemistry and gene expression analysis by single-nuclei RNA-sequencing. We found that there was great variability in the frequency of TDP-43 pathology across and within FTLD-TDP pathological subtypes. Our findings suggest that distinct global transcriptomic profiles may underlie the different pathological subtypes of FTLD-TDP. The most prominent transcriptomic changes were observed in oligodendrocytes and astrocytes, involving multiple hnRNPs across frontotemporal lobar degeneration subtypes compared to controls. Transcriptomic co-expression analysis further revealed that glial clusters were more strongly associated with RNA-processing dysfunction and contributed to disease classification. Together, these findings highlight the involvement of the hnRNP network and glial-specific RNA-processing alterations in FTLD-TDP pathophysiology, offering new insight into the molecular distinctions between pathological subtypes and potential targets for future investigation.",

FTD is a potential comorbidity of idiopathic normal pressure hydrocephalus (iNPH) and carrying the C9-HRE can modify the age-of-onset in iNPH patients. While intermediate-length C9-HRE (<30 repeats) are often considered non-pathogenic, the exact pathological cutoff is unclear. In this study, we assessed whether skin fibroblasts from iNPH patients carrying intermediate C9-HRE display C9-HRE-associated pathological hallmarks and changes in cellular function. C9-HRE-associated RNA foci, present in the long (>60 repeats) C9-HRE carrier fibroblasts, were not detected in those of the intermediate carriers. The number of p62-positive puncta was significantly increased in long but not intermediate C9-HRE carrier fibroblasts, in line with p62-positive intracellular inclusions observed in a brain biopsy from the patient. Induction of autophagy did not suggest any defects in the intermediate carrier fibroblasts. Fibroblasts from the intermediate C9-HRE carriers showed upregulated glycolytic activity, possibly to counteract the slightly reduced mitochondrial respiration. This could not be observed in the long C9-HRE carrier fibroblasts. In conclusion, these data suggest that while the long C9-HRE leads to more severe cellular pathologies than intermediate C9-HRE, the latter might predispose cells to deficits in specific cellular functions, such as energy metabolism.",

While fetal lung signals are known to help initiate labor, the role of the placenta has remained unclear. Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice. Our findings reveal that placental AOC1-spermidine-EIF5A-autophagy axis is essential for parturition timing and offer a potential therapeutic strategy for preterm birth.",

The overlap between FTD and motor neuron disease is increasingly recognized, presenting a complex clinical syndrome characterized by progressive cognitive, behavioral, and motor decline. We describe a 69-year-old patient with a 4-year history of excessive ambulation. Over the last year, behavioral changes including disorganized conduct, irritability, spitting, and cold water foot immersion developed. The patient experienced compelling auditory hallucinations driving her to walk continuously for up to 10 h per day. Four months prior to admission, gait impairment with frequent falls, along with hyperorality developed. Neurological examination revealed asymmetric mild weakness, marked muscle atrophy of facial and limb muscles, hyperreflexia, and impaired postural control. Brain MRI showed diffuse cerebral atrophy; electrophysiological studies indicated probable motor neuron disease; and TRODAT SPECT demonstrated impaired presynaptic dopaminergic function bilaterally, consistent with parkinsonism. Final diagnosis was frontotemporal dementia with probable motor neuron disease. A review of the literature highlights the clinical, radiological, and molecular features of FTD-MND overlap, emphasizing the role of TDP-43 pathology, C9orf72 mutations, and the need for multidisciplinary management. Current strategies are symptomatic, though novel therapies such as antisense oligonucleotides and biomarkers like neurofilament light chain (NfL) show promise. This case highlights the diagnostic complexity of FTD with MND overlap syndrome, emphasizing the need for comprehensive clinical, neuroimaging, and electrophysiological evaluation. Multimodal treatment approaches focusing on behavioral symptoms and functional support are essential for optimizing patient outcomes.",

The autophagy-lysosome system provides essential control of proteotoxic stress and its failure can lead to initiation of apoptosis. However, in aging and neurodegenerative diseases apoptosis is insufficient to account for all neuronal death, and several different cell death types have been reported in these contexts. Here we show that karyoptosis, a distinct form of cell death, can be induced by proteotoxic stress and then develops through nuclear degeneration and cellular expulsion of nuclear material. We establish that karyoptosis is regulated by the p38 kinase signalling pathway, which controls stability of the nuclear lamina protein LaminB1 via direct phosphorylation. We demonstrate that karyoptosis affects neurons in models of amyotrophic lateral sclerosis/frontotemporal dementia (ALS/FTD) pathology. Finally, we identify karyoptotic features in post-mortem frontal cortex of FTD and Alzheimer's disease (AD) patients. Together these findings characterise a form of cell death directly linked to proteotoxic stress and nuclear lamina stability that is associated with neurodegeneration.",

NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.",

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.

        "42358231": "ID: 42358231\nTitle: Spermidine in Alzheimer's Disease: Evidence from Animal Models and Human Studies.\nAbstract: Spermidine is a naturally occurring polyamine involved in multiple cellular processes, including growth regulation, protein translation, and autophagy. Increasing attention has been devoted to its potential neuroprotective effects, particularly in Alzheimer's disease (AD), a neurodegenerative disorder characterized by \u03b2-amyloid and phosphorylated tau accumulation, synaptic dysfunction, and progressive neuronal loss. In this narrative review, we examine potential mechanisms through which spermidine may influence AD pathophysiology and summarize available preclinical and clinical evidence. Preclinical studies indicate that spermidine induces autophagy, a key cellular clearance pathway responsible for removing damaged organelles and aggregated proteins. Because impaired neuronal autophagy contributes to the accumulation of \u03b2-amyloid and tau in AD, increasing intracellular spermidine levels may enhance the degradation of these toxic species. In addition, spermidine exhibits anti-inflammatory and antioxidant properties, attenuates microglial activation, and supports mitochondrial function. In animal models of AD and brain aging, spermidine administration has been associated with improvements in cognitive performance and synaptic function. However, human clinical evidence remains limited and largely inconclusive. Observational studies suggest associations between higher dietary spermidine intake and better cognitive outcomes, but do not establish causality. Randomized clinical trials to date are few, include small and heterogeneous populations, and have not demonstrated consistent effects on primary cognitive endpoints. Overall, spermidine represents a biologically plausible modulator of pathways relevant to neurodegeneration, but translation of preclinical findings into clinical benefit remains uncertain. Current evidence is insufficient to support its use as a therapeutic or preventive intervention in AD, and further well-designed clinical studies are required to clarify its efficacy and mechanisms of action. Alzheimer\u2019s disease is one of the most common causes of memory loss in older adults. Researchers are searching for ways to protect brain cells and slow the biological processes that lead to this disease. One molecule that has recently attracted attention is spermidine, a natural compound found in all living cells and in many foods, including whole grains, legumes, mushrooms, and aged cheeses. Spermidine plays several roles in the body. One of its most important effects is activation of autophagy, a natural cellular process that removes damaged proteins and other cellular waste. This process is relevant to Alzheimer\u2019s disease because the condition is associated with the accumulation of abnormal proteins in the brain. Experimental studies also suggest that spermidine may influence inflammation in the brain, support mitochondrial function (the energy system of cells), and help maintain communication between nerve cells. In this review, we summarized evidence from laboratory experiments, animal studies, and available human research. In animal models of brain aging and Alzheimer\u2019s disease, spermidine consistently shows neuroprotective effects and can improve memory performance. Human evidence is more limited. Observational studies suggest that higher dietary spermidine intake may be associated with better cognitive performance, while clinical trials investigating supplementation have produced mixed results. Spermidine is naturally present in many foods and is increasingly studied in the context of aging and brain health. Overall, current evidence suggests that spermidine may play a role in brain aging. Larger and well-designed clinical studies are needed to clarify its potential relevance for Alzheimer\u2019s disease.",

Increasing evidence indicates that innate immune activation is not merely a secondary response to neuronal injury, but an active driver of disease progression. In this review, we elaborate on how ALS/FTD-associated genetic lesions and pathogenic protein aggregates, including TDP-43, SOD1, FUS, and C9orf72-derived dipeptide repeat proteins, engage three interconnected innate immune pathways: cGAS-STING, NLRP3 inflammasomes, and TREM2-DAP12 signaling. We further highlight emerging crosstalk among these pathways, in which cGAS-STING and NLRP3 reinforce inflammatory signaling, while NLRP3-driven TREM2 shedding may impair microglial clearance and perpetuate proteostatic failure. Understanding this immune network may help define disease subtypes, identify biomarkers, and guide combinatorial therapeutic strategies that suppress harmful inflammation while preserving protective microglial functions.",

While genetic studies have linked ANXA11 mutations (e.g., D40G) to disease, the precise molecular events converting aggregation into neurotoxicity and intercellular propagation remain elusive. We hypothesize that lysosomal integrity serves as a critical checkpoint in ANXA11 proteinopathy and that its failure drives disease progression. To model the human pathology of ANXA11, we generated pre-formed fibrils (PFFs) of wild-type and FTLD/ALS-linked D40G mutant ANXA11. Human iPSC-derived neurons, 3D cerebral organoids, and bulk RNA-sequencing were employed to investigate neurotoxicity. High-resolution imaging, lentiviral knockdown, and biochemical assays were performed to delineate the lysosomal damage response and the subsequent \"prion-like\" spreading of aggregates. The internalized ANXA11 fibrils accumulated in lysosomes, triggering lysosomal membrane permeabilization (LMP). The D40G mutation exacerbated this toxicity, leading to severe LMP, mitochondrial depolarization, and specific transcriptional downregulation of the dynactin subunit ACTR10. Mechanistically, we identified a protective signaling axis involving p38 MAPK, MK2, and HSP27 that senses ANXA11-induced lysosomal damage and initiates lysophagy. Notably, in human cerebral organoids, failure of this lysophagic clearance facilitated the cytoplasmic escape of ANXA11, thereby accelerating its seeding activity and propagation to neighboring cells. Pharmacological or genetic modulation of this pathway significantly altered neuronal survival. Our study established lysosomal rupture as a primary driver of ANXA11-associated neurodegeneration and validated the p38/MK2/HSP27 axis as a crucial defense mechanism in human neural tissue. These findings provide a novel mechanistic link between lysosomal quality control and ANXA11 propagation, highlighting that enhancing lysophagic flux represents a promising translational strategy to halt the progression of FTLD and ALS.",

This disorder is linked to a high disability and morbidity rate, highlighting the critical need for better preventative and treatment techniques. Spermidine (SPD), a naturally occurring polyamine, modulates critical biological activities, including cell proliferation, autophagy, aging, oxidative stress, and inflammation, and has bone-protective properties. The present study investigated whether SPD could attenuate bone loss in a GIOP rat model. Four groups were created: control, SPD (20\u202fmg/kg), dexamethasone (DEX) (7\u202fmg/kg intramuscularly injected once a week for 5 weeks), and DEX\u202f+\u202fSPD. DEX administration significantly disrupted bone homeostasis, as evidenced by decreased osteocalcin levels, elevated C-telopeptide of type I collagen (CTX-1), upregulated receptor activator of nuclear factor kappa-\u03b2 ligand (RANKL) expression, downregulated runt-related transcription factor 2 (RUNX2) and osteoprotegerin (OPG) expression, elevated oxidative stress (increased malondialdehyde and depleted reduced glutathione), and heightened pro-inflammatory cytokines. These biochemical alterations were accompanied by significant deterioration in bone morphometric parameters. Spermidine co-administration markedly attenuated these changes, restoring redox balance, suppressing inflammatory mediators, modulating the RANKL/OPG axis, and partially preserving bone microarchitecture. These findings indicate that SPD shows beneficial effects in safeguarding against GIOP in a rat model, providing a foundation for further preclinical and clinical investigations.",

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

The SQSTM1 protein regulates the degradation of polyubiquitinated proteins and autophagosome formation through its interaction with microtubule-associated protein light chain 3 (MAP1LC3/LC3). However, the molecular mechanisms by which SQSTM1-LC3 binding regulates the autophagy-endolysosomal system (APELS) remain unclear. To elucidate the spatiotemporal role of SQSTM1, we transiently expressed wild-type SQSTM1 or missense mutants carrying mutations in the LC3-interacting region (LIR), fused with the photoconvertible fluorescent protein Dendra2. Live-cell fluorescence imaging and co-localization analyses with markers of the APELS were then performed. Particle analysis of photoconverted or non-photoconverted SQSTM1-positive structures in live cells revealed that the pathogenic L341V variant formed larger structures than the wild-type. Co-localization analyses further showed that both the L341V and artificial LIR3A mutants accumulated in large ubiquitin-positive structures, likely due to impaired localization to autophagosomes. These results suggest that mutations within the LIR differentially affect autophagosome formation and cargo degradation within APELS-related compartments, highlighting the importance of SQSTM1 structural integrity in ALS/FTD pathogenesis.",

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

The literature mostly examined series with disproportionate numbers of LATE-NC over FTLD-TDP. Leveraging a clinicopathological collection of FTLD-TDP (N\u00a0=\u00a0148) from the University of California, San Francisco, we compared demographic, clinical, genetic, and neuropathological features of FTLD-TDP, particularly FTLD-TDP type A (N\u00a0=\u00a039), and LATE-NC (N\u00a0=\u00a042). FTLD-TDP type A cases were younger at onset and death, had shorter disease duration, and frequent genetic causes (GRN, C9ORF72) compared to LATE-NC, which were mostly sporadic and older. Blinded evaluation of middle frontal gyrus (MFG) TDP-43 immunostaining alone proved insufficient to reliably differentiate FTLD-TDP type A from LATE-NC stage 3. However, factoring in all neuropathologic features, FTLD type A and LATE-NC could be differentiated with\u00a0>95% confidence. These overall findings support distinct diagnostic entities for FTLD-TDP and LATE-NC.",

Dysregulation of TMEM175 has been implicated in Parkinson's disease, highlighting the need for small-molecule modulators to probe its physiological and therapeutic roles. We previously screened an FDA-approved compound library for TMEM175 modulators using a plasma membrane overexpression system that enables functional analysis of channel activity. Here, we report the pharmacological characterization of the most potent hit, candesartan cilexetil. In fluorescence-based thallium flux, automated patch-clamp, and manual patch-clamp assays, candesartan cilexetil robustly activates TMEM175 with efficacy comparable with the reference activator DCPIB, whereas its hydrolyzed metabolite candesartan is inactive. Candesartan cilexetil is active only when applied to the extracellular (lysosome lumen-equivalent) side of the channel and is inactive from the cytosolic-facing side. To determine whether activation requires the intact prodrug, we generated analogs that modify or eliminate the cilexetil and ester functionalities. Structure-activity studies show that selected modifications of the cilexetil moiety reduce potency while preserving maximal efficacy, whereas more extensive modification markedly reduces intrinsic activity, indicating that it is an essential pharmacophoric element rather than a simple membrane-permeating handle. Manual patch-clamp wash-off experiments further demonstrate direct, reversible activation without requiring membrane permeation or hydrolysis. Unexpectedly, the nonhydrolyzable analog VU0982645 exhibits minimal intrinsic activity yet produces robust synergistic activation with DCPIB. Together, these findings establish the cilexetil handle as a key pharmacophoric element and support synergistic modulation as a tractable mechanism for activating TMEM175.NEW & NOTEWORTHY We introduce a new therapeutic paradigm for TMEM175 targeting by demonstrating that synergistic agonist pairs can drive robust channel activation. Beyond identifying candesartan cilexetil as a moderately potent activator with a previously unrecognized pharmacophoric cilexetil moiety, we show that a minimally active analog can dramatically potentiate activation in combination with DCPIB. This synergistic strategy establishes TMEM175 as a tractable therapeutic target and reveals coagonism as a powerful mechanism to modulate lysosomal ion channels.",

However, how psychological stress regulates HSC function remains incompletely understood. Here, we show that psychological stress impairs HSC self-renewal and lymphoid differentiation, inducing aging-like phenotypes. Stress suppresses neuronal activity in the medial prefrontal cortex (mPFC) and periaqueductal gray (PAG), leading to HSC dysfunction, whereas chemogenetic activation of these regions restores HSC function. Psychological stress or chemogenetic inhibition of the mPFC and PAG reduces the abundance of L. reuteri in the gut microbiota and lowers spermidine levels. Mechanistically, spermidine depletion suppresses mitochondrial autophagy, promotes mitochondrial peroxidative stress, and increases ferroptotic stress in HSCs. We further demonstrate that mPFC and PAG activity regulate the intestinal environment through a sympathetic pathway, reducing intestinal mucin levels, L. reuteri abundance, and spermidine levels. These findings identify a brain-gut-bone marrow axis linking psychological stress to aging-like HSC dysfunction through sympathetic regulation of intestinal microbiota and spermidine metabolism.",

However, disease-modifying therapies targeting this pathway remain unavailable. Here, we generated induced pluripotent stem cells (iPSCs) from a PARK9 patient carrying an ATP13A2 mutation and established mutation-corrected isogenic control iPSCs. PARK9 iPSC-derived neurons recapitulated lysosomal dysfunction-associated cellular phenotypes, including impaired lysosomal acidification, reduced mature cathepsin D levels, CD63-positive vesicle accumulation, LC3B-positive autophagosome accumulation, cytoplasmic pSer129 \u03b1-synuclein accumulation, and increased cleaved caspase-3 signals. These phenotypes were ameliorated in mutation-corrected neurons, supporting the contribution of ATP13A2 dysfunction to these abnormalities. We then performed high-content imaging-based compound screening targeting LC3B-positive autophagosome accumulation in PARK9 neurons. A three-step workflow identified 19 candidate compounds that reduced autophagosome accumulation consistent with partial improvement of lysosome-dependent downstream autophagosome processing rather than simple suppression of autophagosome formation. Among these, paroxetine, Ro 25-6981, amisulpride, and PK11195 showed additional, compound-dependent effects on PARK9-associated phenotypes, including lysosomal acidification, CD63-positive vesicle accumulation, cytoplasmic pSer129 \u03b1-synuclein signals, and cleaved caspase-3 signals. These findings establish PARK9 iPSC-derived neurons as a useful model of lysosomal dysfunction-associated PD pathology and provide a practical screening platform for identifying candidate compounds that modulate autophagy-lysosome pathway-related cellular phenotypes.",

This study aimed to elucidate the protective effect of agmatine (AGM) on sepsis-induced intestinal injury and its mitochondrial-targeted antiapoptotic mechanism in intestinal epithelial cells (IECs). We verified the transport and subcellular localization of AGM in IECs via fluorescence assays and established in vitro and in vivo IEC apoptosis models. Functional evaluations using cell viability assays, laser confocal imaging, flow cytometry, transmission electron microscopy, and multiomics techniques were performed. AGM attenuated sepsis-induced intestinal injury, as evidenced by its ability to lower the serum levels of intestinal damage markers in septic mice, attenuate inflammatory factor production and pathological damage in the intestine, and reduce IEC apoptosis. AGM entered IECs via the polyamine transport system (PTS), but not the NMDA receptor, and inhibited IEC apoptosis induced by TNF\u03b1/CHX or TNF\u03b1/ActD. Notably, AGM exerted its antiapoptotic effect by targeting the mitochondrial imidazoline I2 receptor (I2R). Mechanistically, AGM induced mitophagy by decreasing the mitochondrial membrane potential without altering mitochondrial number or function, as ROS production, calcium ion influx, ATP generation, and oxygen consumption were unchanged. AGM also increased autophagic flux, as confirmed upon treatment with various autophagy inhibitors. AGM alleviates sepsis-induced intestinal injury via the PTS-I2R axis by promoting mitophagy and autophagic flux to inhibit IEC apoptosis, laying a foundation for the use of AGM as a potential nutritional supplement or therapeutic agent for sepsis-induced intestinal injury.",
        "42410910": "ID: 42410910\nTitle: Targeting the SNAI1-LAMP3 axis to restore lysosomal function and alleviate autophagic flux impairment to delay retinal degeneration.\nAbstract: Retinal degenerative diseases are a leading cause of irreversible blindness. Their pathogenesis is intricately linked to oxidative stress-induced dysfunction of retinal pigment epithelial (RPE) cells and subsequent retinal degeneration. Macroautophagy/autophagy, a critical cellular degradation pathway, plays a vital role in maintaining RPE homeostasis, yet its dysregulation in retinal degenerative diseases remains poorly understood. In this study, we observed that sodium iodate (NaIO3), an oxidative stress inducer, triggered lysosomal dysfunction via lysosomal membrane permeabilization (LMP), thereby impairing autophagic flux in RPE cells and exacerbating retinal degeneration. RNA sequencing identified LAMP3 (lysosomal-associated membrane protein 3) as a downregulated gene following NaIO3 treatment. Functionally, LAMP3 overexpression alleviated NaIO3-induced LMP, improved lysosomal function, and alleviated autophagic impairment. Furthermore, upregulation of LAMP3 reduced oxidative stress and apoptosis in RPE cells, while alleviating retinal degeneration in a NaIO3-induced mouse model. Mechanistically, our data suggested that NaIO3 upregulated the transcription factor SNAI1, which acts as a transcriptional repressor of LAMP3. SNAI1 knockdown increased LAMP3 expression, thereby facilitating the recovery of lysosomal function and the alleviation of autophagic impairment. Collectively, our findings indicate that the SNAI1-LAMP3 axis contributes to the regulation of the autophagy-lysosomal pathway in retinal degeneration, highlighting a potential therapeutic target for delaying disease progression.Abbreviations: AMD: age-related macular degeneration; AO: acridine orange; Baf A1: bafilomycin A1; BAX: BCL2-associated X protein; BCL2: B cell leukemia/lymphoma 2; BSA: bovine serum albumin; CCK-8: cell counting kit-8; ChIP: chromatin immunoprecipitation; CM-H2DCFDA: chloromethyl-2',7'-dichlorodihydrofluorescein diacetate; CTSD: cathepsin D; DAPI: 4',6-diamidino-2-phenylindole; DEGs: differentially expressed genes; DHE: dihydroethidium; EdU: 5-ethynyl-2'-deoxyuridine; ERG: electroretinography; GSEA: gene set enrichment analysis; H&E: hematoxylin and eosin; HsRPE: human primary retinal pigment epithelial; JC-1: 5,5',6,6'-tetrachloro-1,1',3,3'-tetraethylbenzimidazolylcarbocyanine iodide; LAMP1: lysosomal-associated membrane protein 1; LAMP2: lysosomal-associated membrane protein 2; LAMP3: lysosomal-associated membrane protein 3; LGALS3: lectin, galactose binding, soluble 3; LLOMe: leu-leu methyl ester; LMP: lysosomal membrane permeabilization; MAP1LC3B/LC3B: microtubule-associated protein 1 light chain 3 beta; MMP: mitochondrial membrane potential; NAC: N-acetyl-L-cysteine; NaIO3: sodium iodte; NC: negative control; OCT: optical coherence tomography; PCA: principal component analysis; PI: propidium iodide; qRT-PCR: quantitative real-time polymerase chain reaction; Rapa: rapamycin; ROS: reactive oxygen species; RP: retinitis pigmentosa; RPE: retinal pigment epithelium; RPE65: retinal pigment epithelium 65; siRNA: small interfering RNA; SNAI1: snail family zinc finger 1; SQSTM1/p62: sequestosome 1; TJP1/ZO-1: tight junction protein 1; ZNF135: zinc finger protein 135.",

Emerging evidence suggests that intracellular zinc dynamics regulate lysosomal function by modulating processes such as acidification and lysosomal biogenesis. We previously identified 1H10 as an AMP-activated protein kinase (AMPK) inhibitor and subsequently demonstrated its zinc-binding capacity and ability to regulate intracellular zinc homeostasis. Building on our prior findings that intra-lysosomal zinc promotes acidification and activates transcription factor EB (TFEB), we investigated whether 1H10 enhances lysosomal function through zinc mobilization in neurons, thereby improving autophagy and reducing pathological protein accumulation. In primary cortical neurons, 1H10 increased lysosomal abundance and enhanced lysosomal degradative capacity in a zinc-dependent manner, as demonstrated by increased cathepsin B activity and DQ-BSA degradation. It alleviated lysosomal dysfunction induced by v-ATPase inhibition and promoted autophagic flux, leading to reduced accumulation of amyloid-\u03b2 (A\u03b2) and tau in neuronal models. In 5XFAD mice, 1H10 treatment showed trends toward improved spatial learning in the Morris water maze, reduced tau phosphorylation at Thr205 and Ser214, normalized LC3-II levels, and restored autophagic-lysosomal homeostasis, without significant changes in extracellular amyloid plaque burden. These findings indicate that zinc-mediated lysosomal activation by 1H10 enhances the autophagy-lysosomal pathway and attenuates tau pathology in AD models, suggesting that targeting lysosomal function may represent a potential therapeutic strategy for neurodegenerative disorders characterized by impaired proteostasis.",

Pathophysiological conditions in the cell cause the protein quality control system to depend on the autophagy-lysosome pathway (ALP) for degradation of accumulated misfolded proteins and mitochondrial turnover. BCL2-associated athanogene 3 (BAG3) protein has a role in initiating the ALP. Our aim was to ameliorate disease processes resulting from mitochondrial abnormalities and misfolded protein aggregation by upregulating the ALP through overexpression of human BAG3 (hBAG3). The VCP-A232E mouse, a model for hIBM, received AAVrh74.tMCK.hBAG3 systemically at 3 months of age, and outcome measures, including functional, histological, and molecular studies, were assessed 9 months post-gene delivery. hBAG3 treatment improved treadmill running distance and rotarod duration, reduced the number of TDP-43-positive aggregates, and decreased the number of fibers showing abnormalities in mitochondrial enzyme histochemistry, compared with the untreated cohort. Moreover, hBAG3 gene therapy resulted in improvements in mitophagy and mitochondrial homeostasis observed as increased levels in mitophagy markers Parkin and Bnip3, mitochondria biogenesis marker Pgc1\u03b1 and mitochondrial DNA-encoded subunits of complex IV, Cox1 and Cox3. In addition, the LC-II/I ratio increased, indicating increased autophagic flux. Our study presents evidence that the strategy of supporting the ALP system by overexpressing BAG3 has potential therapeutic use for myodegenerative conditions associated with abnormal protein aggregates and mitochondrial turnover.",

Here, we defined the lncRNA landscape across iPSC-derived neurons, astrocytes, and microglia harboring the frontotemporal dementia-associated MAPT IVS10+16 mutation and investigated how lncRNA dysregulation interfaces with tau pathology. Transcriptomic analyses revealed extensive cell-type specific lncRNA expression changes, with neurons exhibiting the greatest degree of mutation-associated remodeling. Comparative analyses with MAPT IVS10+16 patient brain tissue identified NORAD and MIR22HG as lncRNAs significantly dysregulated across all three cell types and human brains. NORAD was also altered in Alzheimer's disease and Parkinson's disease brains, suggesting a broader role in neurodegenerative disease. Mechanistically, NORAD-associated protein networks converged on pathways related to RNA regulation, cytoskeletal organization, proteostasis, and tau interaction networks. Given the established role of NORAD in regulating PUM1 and PUM2 RNA-binding (pumilio) proteins, we examined the NORAD-pumilio axis and identified enrichment of pumilio-associated pathways linked to autophagy, endocytosis, proteostasis, and cytoskeletal regulation. NORAD depletion reduced tau seeding and uptake, whereas functional depletion of PUM1 or PUM2 increased both processes, supporting an antagonistic relationship between NORAD and pumilio signaling in modulation of tau aggregation. Together, these findings identify widespread lncRNA dysregulation across neural cell types in the setting of a MAPT mutation and nominate the NORAD-pumilio axis as a regulatory pathway linking RNA homeostasis and tau propagation biology.",
        "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.",

Polyamines including spermine and spermidine are interconvertible metabolites whose longevity-promoting effects have traditionally been attributed to autophagy induction. In addition, recent evidence identifies spermine as an endogenous Fe2+ chelator that suppresses ferroptosis, thereby complementing the autophagy-inducing activity of spermidine. Indeed, spermidine inhibits EP300 acetyltransferase activity and supports hypusination-dependent activation of TFEB, both leading to autophagy. However, enhanced autophagic flux may increase susceptibility to ferroptosis through ferritinophagy and lipid remodeling. In parallel, polyamine catabolism generates H2O2 and acrolein, both of which facilitate lipid peroxidation and ferroptotic demise. The discovery that spermine directly chelates redox-active Fe2+ closes a conceptual gap by explaining how polyamine supplementation can promote longevity while avoiding excessive ferroptotic cell loss. Multiple lines of evidence including metabolomics, isotope tracing, cell-free lipid peroxidation systems, Fe2+-binding biophysics, mass spectrometry, Raman spectroscopy, nuclear magnetic resonance and disease models demonstrate that spermine limits labile iron and ferroptosis. Together, these findings support a unified model in which spermidine-driven autophagy and spermine-mediated ferroptosis inhibition cooperate to preserve tissue homeostasis and healthspan.",

A structured narrative review of the literature was conducted using PubMed/MEDLINE up to March 2025. Relevant studies including clinical trials, observational studies, mechanistic research, and reviews were selected to summarise the molecular mechanisms and cardiovascular effects of HCQ. HCQ exerts multiple beneficial cardiovascular effects through anti-inflammatory, antithrombotic, metabolic, and endothelial-protective mechanisms. It reduces cytokine production, oxidative stress, platelet activation, and improves lipid and glucose profiles, contributing to decreased cardiovascular risk in patients with systemic autoimmune diseases. However, HCQ may also induce cardiotoxic effects, particularly with long-term use or high cumulative doses. These include QT interval prolongation, conduction abnormalities, and a rare but severe form of cardiomyopathy related to lysosomal dysfunction and impaired autophagy. The risk is higher in patients with advanced age, renal dysfunction, pre-existing heart disease, or concomitant use of QT-prolonging drugs. HCQ has a complex and context-dependent cardiovascular profile. While generally cardioprotective at standard doses, it may lead to rare but serious cardiac adverse effects in highrisk patients. A risk-adapted monitoring strategy is essential to optimise its benefit-risk balance in clinical practice.",

Through transcriptomic screening of an experimental autoimmune uveitis (EAU) model and validation in peripheral blood mononuclear cells from Vogt-Koyanagi-Harada patients, we identified MAP1S (microtubule-associated protein 1S) as a pivotal, conserved regulator. Here, we demonstrate that MAP1S constrains pathogenic Th17 responses and alleviates EAU through a dual mechanism coordinating transcriptional control and autophagic degradation. Mechanistically, MAP1S binds to EGR2 (early growth response 2) and restrains its acetylation at Lys368, thereby suppressing Lcn2 (lipocalin 2) transcription. Besides, MAP1S facilitates autophagosome biogenesis and lysosomal trafficking, promoting the autophagic clearance of LCN2 protein. Notably, MAP1S deficiency enhances EGR2 acetylation, increases Lcn2 transcription, disrupts autophagosome trafficking, impairs LCN2 degradation, and promotes LCN2 accumulation, collectively driving Th17 polarization and exacerbating EAU pathology. Adoptive transfer of cervical lymph node cells from map1s knockout mice reproduced severe disease in wild-type recipients. Moreover, pharmacological activation of MAP1S with spermidine suppressed Th17 responses and alleviated disease severity. Our findings establish MAP1S as a critical node integrating acetylation signaling of EGR2 and autophagic flux to govern LCN2\u00a0homeostasis and Th17 pathogenicity, revealing a promising therapeutic target for autoimmune uveitis and potentially other Th17-mediated diseases.Abbreviations: AAV: adeno-associated virus; ACOD1: aconitate decarboxylase 1; AU: autoimmune uveitis; BCL2: B cell leukemia/lymphoma 2; CDLNs: cervical draining lymph nodes; CFA: complete Freund's adjuvant; ChIP: chromatin immunoprecipitation; Co-IP: co-immunoprecipitation; CQ: chloroquine; EAU: experimental autoimmune uveitis; EGR2: early growth response 2; GDF15: growth differentiation factor 15; HDAC4: histone deacetylase 4; HDAC6: histone deacetylase 6; IL17: interleukin 17; IL17f: interleukin 17f; IL22: interleukin 22; K: lysine; KAT2A/GCN5: K(lysine) acetyltransferase 2A; KO: knockout; LCN2: lipocalin 2; MAP1LC3/LC3: microtubule-associated protein 1 light chain 3; MAP1S: microtubule-associated protein 1S; MS: mass spectrometry; PBMC: peripheral blood mononuclear cell; PCR: polymerase chain rection; PPI: protein-protein interaction; PTX: pertussis toxin; qPCR: quantitative PCR; RT-qPCR: reverse transcription and quantitative real-time RCR; SAA3: serum amyloid A3; SPD: spermidine; Th1 cells: T helper 1 cells; Th17 cells: T helper 17 cells; TF: transcriptional factor; Tregcells: regulatory T cells; VKH disease: Vogt-Koyanagi-Harada disease; WT: wild-type.",

Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA.",

DEHP exposure has been linked to neurotoxicity in Alzheimer's disease (AD), yet the underlying mechanisms remain unclear. Here, we found that DEHP exacerbated amyloid-beta (A\u03b2)-induced toxicity in transgenic AD Caenorhabditis elegans (C. elegans) models. Meanwhile, the accumulation of SQST-1 was increased, indicating that the autophagic flux was impaired. Consistently, A\u03b2 deposition was elevated in DEHP-treated AD C. elegans. Further investigation revealed that DEHP treatment resulted in lysosomal dysfunction accompanied by a significant decrease in lysosome number. The expression of hlh-30, a key transcription factor involved in lysosomal biogenesis, as well as its downstream lysosome-related genes, including cup-5, vha-17, and lmp-1, was reduced by DEHP. Moreover, hlh-30 RNAi abolished the exacerbation of A\u03b2 toxicity induced by DEHP, indicating that the modulation of hlh-30 was a critical mechanism underlying the effects of DEHP. Additionally, DEHP aggravated oxidative stress in AD C. elegans, while the antioxidant N-acetylcysteine alleviated lysosomal impairment and reduced A\u03b2 deposition, suggesting that the elevated oxidative stress was a key contributor to DEHP-induced lysosomal dysfunction and autophagy impairment. These findings highlight lysosomal impairment as a key mechanism contributing to DEHP-exacerbated toxicity in AD models, and suggest the possibility of using antioxidants to prevent DEHP-induced toxicity.",

Lysosomes are key organelles responsible for the degradation and recycling of intracellular components and are essential for maintaining metabolic and nutrient homeostasis. Although lysosomal dysfunction is closely associated with cellular aging, the role of V-ATPase in regulating lysosomal function during photoaging remains incompletely understood. By screening a V-ATPase-targeted siRNA library and validating the results using publicly available single-cell transcriptomic datasets, we identified ATP6V1A as a key regulator of UVB-induced cellular senescence. Furthermore, ATP6V1A knockdown exacerbated the UVB-induced cellular senescence and impaired lysosomal acidification and membrane integrity, whereas ATP6V1A overexpression effectively alleviated keratinocyte senescence, lysosomal dysfunction and autophagy inhibition. Moreover, treatment with the V-ATPase inhibitor BafA1 aggregated cellular senescence phenotype and autophagy inhibition and this phenomenon partially reversed by ATP6V1A overexpression. Collectively, ATP6V1A promotes autophagy by regulating lysosomal function, thereby relieving UVB-induced cellular senescence.",

Hypobaric hypoxia at high altitudes accelerates aging, while D-galactose (D-gal) injection mimics metabolic aging. The gut microbiota is a key regulator of aging, but whether indigenous probiotics from the high plateaus of Tibet exert comparable or differential efficacy against distinct aging etiologies remains unclear. In this study, we systematically evaluated the protective effects of Lactiplantibacillus plantarum AL4510, a novel probiotic strain isolated from traditional fermented goat milk on the Qinghai-Tibet Plateau. We used both D-gal-induced and hypobaric hypoxia-induced aging models established simultaneously within the same experimental system. AL4510 significantly alleviated oxidative stress in both models, as evidenced by restored serum superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and reduced malondialdehyde (MDA) levels. Systemic inflammation was attenuated, with lower interleukin-1\u03b2 (IL-1\u03b2) and tumor necrosis factor-alpha (TNF-\u03b1) concentrations. Cellular senescence, assessed using senescence-associated \u03b2-galactosidase (SA-\u03b2-gal) and p16 immunofluorescence, was markedly reduced in both liver and colon tissues by approximately 50-60%. The probiotic rebalanced the gut microbiota composition by consistently suppressing a synergistic pathogenic cluster comprising Desulfovibrio, Bilophila, and Helicobacter while promoting beneficial genera including Akkermansia, Muribaculum, and Lactobacillus. Metabolomic profiling revealed that AL4510 replenished short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate in both models, indicating restoration of gut fermentative capacity. Importantly, AL4510 engaged in stress-specific metabolic reprogramming: in the D-gal model, it elevated the levels of autophagy-inducing polyamine spermidine and the anti-inflammatory lipoxin B4; in the hypoxia model, it upregulated neuroprotective catalpol, lupeol, and energy-related calcium pantothenate. Integrative correlation and co-occurrence network analyses suggested that AL4510 was associated with a beneficial microbial consortium that correlated with host metabolism potentially involving the microbiota-SCFA axis. Collectively, these findings suggest that AL4510 exerts broad spectrum anti-aging effects potentially involving a \"dual-track\" mechanism: convergent restoration of gut ecological balance and divergent, stress-adapted reprogramming of host metabolism. This study provides a scientific basis for developing AL4510 as a functional probiotic ingredient or postbiotic formulation for high-altitude adaptation, metabolic anti-aging interventions, and gut-targeted nutritional strategies.",

Progranulin haploinsufficiency, a leading genetic cause of familial FTD, disrupts lysosomal function, lipid metabolism, autophagy, and neuroimmune signaling across multiple cell types. Increasing evidence indicates that microglia are particularly sensitive to progranulin loss, exhibiting elevated complement activation that contributes to TDP-43 proteinopathy and neuronal dysfunction. Here, we investigate the biological role of restoring progranulin exclusively within microglia by transplanting human induced pluripotent stem cell-derived microglial progenitors into progranulin (Grn)-deficient mice. We find that engraftment of wild-type, but not Grn-deficient, human microglia restore brain-wide progranulin levels, normalize microglial transcriptional states, and ameliorate pathological, functional, and behavioral phenotypes associated with progranulin loss. Because human microglia are the only source of progranulin in this system, these findings demonstrate that microglial progranulin is sufficient to restore key aspects of cellular, circuit, and behavioral homeostasis in a progranulin-deficient FTD model. More broadly, this work highlights a central, microglia-intrinsic role for progranulin in maintaining brain function and provides a framework for dissecting microglia-specific mechanisms across FTD and related neurodegenerative disorders.",

Emerging evidence implicates lipid dysregulation in neurodegeneration, but its extent across FTLD subtypes and how it compares to AD are unclear. Here, we performed integrated lipidomic and proteomic analyses of matched frontal (disease-vulnerable) and occipital (relatively spared) post-mortem cortices from individuals with genetic and sporadic FTLD-TDP, FTLD-tau (Pick disease's, PiD), AD, and controls. FTLD and AD exhibited convergent lipid alterations, including reduced levels of cardiolipins and phosphatidylethanolamines, alongside increased gangliosides, diacylglycerols, cholesterol esters, acylcarnitines, and coenzyme Q, with generally greater changes in FTLD frontal cortex. FTLD displayed additional alterations, including reductions in bis(monoacylglycerol)phosphate, ceramides, phosphatidylserines, phosphatidylinositols, and sulfatides. These lipid changes were accompanied by proteomic alterations involving lysosomal proteins, phospholipases, phospholipid remodeling enzymes, and fatty acid oxidation pathways. Although lipidomic and proteomic signatures were broadly shared across FTLD subtypes, GRN associated FTLD-TDP and PiD showed the most extensive alterations. Triglycerides were selectively reduced in PiD in association with decreased DGAT1 expression, whereas cholesterol esters were elevated across all subtypes except C9orf72 associated FTLD-TDP. These findings identify shared disruptions in lipid homeostasis and lysosomal lipid metabolism across FTLD and AD, highlighting convergent metabolic pathways underlying neurodegeneration.",

Its acetyl group enables transport via monocarboxylate transporters, supporting blood-brain barrier penetration and efficient cellular uptake. Inside cells, levacetylleucine is metabolised by acylases, generating elevated levels of L-leucine that enhance mitochondrial bioenergetics and is thought to ameliorate lysosomal dysfunction indirectly. Here, we describe a direct effect of levacetylleucine on lysosomal regulation through modulation of TFEB, the master transcription factor for lysosomal and autophagy genes. Levacetylleucine rapidly alters TFEB translocation between the cytoplasm and the nucleus in a biphasic, homeostasis-restoring manner. In wild-type HeLa cells, levacetylleucine promotes TFEB activation and nuclear localisation. However, in NPC1 disease models, where we show that TFEB is over-activated and enriched in the nucleus due to lysosomal stress, levacetylleucine reduces nuclear TFEB and restores a more normal cytoplasmic-to-nuclear balance. These effects occur at clinically relevant concentrations associated with lysosomal storage reduction. The effects of the drug are stereospecific: while the L-enantiomer is active, the D-enantiomer and racemate show no effect, revealing the antagonistic properties of the D-enantiomer. This bidirectional normalisation of TFEB activity highlights a direct mechanism through which levacetylleucine modulates lysosomal and autophagic pathways in the HeLa cell model, giving mechanistic insight into its therapeutic potential in NPC, and also across diverse neurological and neurodevelopmental disorders.",

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application.",

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.",
        "42477140": "ID: 42477140\nTitle: Mitochondrial-derived vesicles drive budding-type fission of damaged lysosomes.\nAbstract: Lysosomes are central degradative organelles essential for cellular homeostasis, yet the mechanisms that maintain their integrity and function under stress remain incompletely understood. Here we identify a previously unrecognized lysosomal renewal process, termed budding-type fission (B-fission), which restores lysosomal function during hypoxia-reoxygenation stress. During B-fission, damaged lysosomes generate membrane buds that undergo scission to form small, fully functional lysosomes, independently of autophagic lysosome reformation. Mechanistically, mitochondrial-derived vesicles (MDVs) deliver the fission adaptor MFF to lysosomes, where MFF recruits the dynamin-related GTPase DRP1 to drive membrane scission. MIRO2 promotes the formation of MFF+ MDVs through direct interaction with MFF, while the lysosomal membrane protein ITM2C binds MIRO2 to tether and guide MFF+ MDVs to lysosomes, enabling efficient MFF delivery and subsequent B-fission. Notably, AMPK activation by 991 or metformin promotes MFF-dependent lysosomal B-fission under normoxic conditions, whereas AMPK inhibition by dorsomorphin suppresses B-fission during hypoxia-reoxygenation. This stress-responsive ITM2C-MIRO2-MFF-DRP1 axis co-opts the mitochondrial division machinery to drive lysosomal fission from damaged lysosomes, thereby enabling the undamaged components to reorganize into daughter lysosomes and promote lysosomal renewal. Thus, our findings uncover a fundamental mode of lysosomal renewal and reveal an unexpected role for MDV-mediated mitochondria-lysosome communication in mediating lysosomal quality control during ischaemia-reperfusion and related stresses.",

Here, by integrating population-scale epidemiology with mechanistic dissection, we identify platelet factor 4 (PF4) as the central driver of a circulating neuroprotective axis that restores proteostasis and rescues ALS. In a prospective cohort of >500\u00a0000 UK Biobank participants, platelet indices were strongly associated with ALS risk, and serum PF4 levels were significantly reduced in ALS patients. Systemic administration of recombinant PF4 in hSOD1G93A mice produced dramatic therapeutic effects: extended survival, preserved motor function, attenuated neuroinflammation, and reduced neuromuscular junction denervation. Remarkably, this efficacy appears pathology-selective-robust in SOD1-driven models but shows no observable effect in TDP-43 or C9orf72 ALS models. Mechanistically, PF4 achieves what few molecules can: it engages the cell surface receptor LRP1 to activate the TBK1-OPTN signaling axis, restoring impaired autophagic flux through a PINK1/Parkin-independent pathway requiring ATG7, establishing a previously unrecognized peripheral platelet-autophagy-neuron axis that facilitates the co-clearance of pathological SOD1 aggregates and damaged mitochondria. This study unveils PF4 as a first-in-class circulating autophagy regulator with therapeutic potential in ALS. Beyond identifying a candidate biomarker and drug lead, it reveals that systemic factors can directly engage central proteostatic machinery-opening a new frontier for ALS therapy.",

IL17A (interleukin 17A), a proinflammatory cytokine primarily secreted by Th17 and \u03b3\u03b4 T cells, has been implicated in immune-mediated neurodegeneration. However, the role of IL17A in the pathogenesis of HD remains poorly understood. Here, we identify IL17A as a critical pathogenic factor in HD that promotes neuroinflammation, mHTT aggregation, and autophagy-lysosomal dysfunction. IL17A disrupts autophagic flux by downregulating CTSB and CTSD, inducing SQSTM1/p62 and MAP1LC3B-II/LC3-II accumulation, and impairing lysosomal reformation. Mechanistically, IL17A suppresses lysosomal biogenesis by inhibiting the nuclear translocation of TFE3. This regulation occurs via a novel GSK3B/GSK-3\u03b2-TFE3 signaling pathway. Therapeutic neutralization of IL17A with a monoclonal antibody (IL17A mAb) ameliorates disease phenotypes in R6/2 HD mice, improving motor performance, extending survival, and reducing gliosis. IL17A mAb also attenuates mHTT aggregation and enhances neuroprotective signaling, as evidenced by increased expression of DLG4/PSD-95, phosphorylated CREB1, and BDNF. Moreover, IL17A mAb restores autophagy-lysosomal function by facilitating the clearance of protein aggregates and upregulating lysosomal enzymes and biogenesis markers, including CTSB, CTSD, PIP5K1A, and LAMP2. These findings establish IL17A as a key modulator of HD pathophysiology and highlight IL17A inhibition as a promising therapeutic strategy for targeting autophagy-lysosomal dysfunction in HD.",

Although these disorders are often clinically defined by symptoms and affected brain regions, many are mechanistically linked to abnormal protein accumulation, misfolding, impaired proteostasis, RNA dysregulation, mitochondrial dysfunction, and neuroinflammation. In this Perspective article, I discuss major neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, dementia with Lewy bodies, multiple system atrophy, amyotrophic lateral sclerosis, frontotemporal dementia, Huntington's disease, prion diseases, spinocerebellar ataxias, and spinal muscular atrophy, through the lens of disease-associated proteins and experimental modeling. I argue that a protein-centered framework provides a useful approach for understanding disease mechanisms and selecting transgenic mouse models, while recognizing that aging, cellular context, neuroinflammation, mitochondrial dysfunction, vascular dysfunction, and other disease modifiers also shape neurodegeneration. Transgenic and genetically engineered mouse models have been essential for dissecting the pathogenic roles of amyloid-\u03b2, tau, \u03b1-synuclein, TDP-43, SOD1, FUS, C9ORF72-associated dipeptide repeat proteins, mutant huntingtin, prion protein, ataxins, and SMN deficiency. However, these models have important limitations, including artificial overexpression, familial mutation bias, species differences, and incomplete representation of aging-related sporadic diseases. Rather than seeking a single \"best\" model, a more productive strategy is to adopt model portfolios tailored to specific biological questions and to integrate mouse studies with human cellular models, postmortem tissue, omics approaches, and biomarker-based validation. Such an approach may improve mechanistic insight, strengthen translational relevance, and enhance the predictive value of preclinical neurodegenerative disease research.",

Chronic exposure to HGA promotes oxidative stress, chondroptosis, secondary amyloidosis, and impaired autophagy, an essential process for maintaining chondrocyte homeostasis. This study investigated the mechanisms potentially involved in autophagy dysregulation in AKU using the human C20/A4 chondrocyte line treated with 0.1 mM HGA, an established in vitro model of the disease. The findings were then verified using chondrocyte cells and cartilage tissue obtained from AKU biopsies. HGA treatment induced a time-dependent increase in oxidative stress, evidenced by elevated ROS levels, 4-HNE accumulation, and overproduction of mitochondrial superoxide. Autophagy assessment showed an early increase in autophagy-related markers, with increased LC3 and p62 expression and enhanced lysosomal biogenesis (LAMP1). However, prolonged HGA exposure was associated with reduced LC3/LAMP1 colocalization, persistent p62 accumulation, altered acidic compartment staining, and accumulation of autophagy-related structures, supporting a dysregulation of the autophagy-lysosomal pathway. Live-cell imaging further supported a transition from functional autophagy to lysosomal failure under chronic oxidative stress. Overall, this study suggests that prolonged HGA exposure disrupts the interplay between oxidative stress and autophagic flux. The progressive collapse of these adaptive mechanisms may contribute to chondrocyte degeneration and to the pathogenesis of cartilage damage in AKU.",

We argue that they are better understood as variations on a single theme: the breakdown of the autophagy-lysosome system within cardiomyocytes. In the healthy heart, this system clears damaged proteins and organelles and is regulated by mTORC1 and the master regulator TFEB. Once lysosomal degradation or autophagosome-lysosome fusion fails, undegraded substrates and defective mitochondria accumulate, driving hypertrophy, interstitial fibrosis, and conduction disease. Danon disease, resulting from the loss of LAMP2, is the clearest example of a primary defect in autophagic flux, whereas the glycogen storage of Pompe disease and the globotriaosylceramide accumulation of Fabry disease impair flux through different upstream mechanisms that converge on the same downstream injury. The same framework extends to other storage disorders with cardiac involvement, such as mucopolysaccharidosis (MPS). We trace this shared pathobiology from molecule to bedside, examine biomarkers that reflect lysosomal and autophagic dysfunction rather than storage alone, and re-examine treatment in that light: why enzyme replacement therapy corrects substrate accumulation but leaves much of the autophagic and mitochondrial damage unresolved, and why gene therapy-particularly AAV9-LAMP2B for Danon disease-together with autophagy- and TFEB-directed strategies may help close that gap. Viewing these disorders through a single mechanistic lens reshapes how we monitor them and where future therapies should be directed.",

Although these disorders have different clinical features which affect cognition, movement and other vital body functions, they share key underlying molecular and cellular processes. This starts with protein misfolding and aggregation, mitochondrial dysfunction, oxidative stress, dysregulated protein homeostasis, neuroinflammation, and disrupted cell death pathways. Recent findings have added disease-specific processes, like amyloid-\u03b2 and tau aggregates in AD, \u03b1-synuclein aggregation and mitophagy failure in PD's, TDP-43-related impaired RNA metabolism in ALS, and mutant huntingtin causing transcription aberrations in HD. Protein interactome network analysis showed mechanistic crosstalk between pathogenic proteins of AD and PD. New evidence highlights how lysosomal dysfunction, endoplasmic reticulum stress, and microglial activation, act as a common axis in neurodegeneration. Advancements in genomics and epigenomics have found shared genetic risk loci and regulatory processes that affect how diseases develop and progress. Simultaneously, new biomarkers like circulating microRNAs, exosome-related pathological proteins, neurofilament light chain, inflammatory cytokines, and microglial activation markers are powering early diagnosis tools and disease variations. New imaging techniques also allow for the identification of protein aggregations before symptoms appear.

We performed single-nucleus RNA sequencing of frontoinsular cortex, a region affected early in behavioral variant FTD, across individuals with C9orf72-associated and sporadic FTD-MND spectrum disease. By enriching for large projection neurons, we resolved molecular subtypes of layer 5 extratelencephalic neurons, including von Economo neurons, and identified selective depletion of specific layer 2/3 and layer 5 neuron subtypes, convergent across genotypes. Despite selective neuronal loss, disease-associated transcriptional changes were convergent across excitatory neuron populations, suggesting that they reflect upstream pathophysiology or shared responses to local neurodegeneration. By relating neighborhood-level depletion in disease to gene expression in controls, we found that baseline cellular respiration and ATP synthesis predict neuronal vulnerability in disease. These findings define molecular correlates of selective neuronal vulnerability in FTD and provide a framework linking cell type and state to neurodegeneration.",

Its dynamic function is closely intertwined with lipid metabolism, forming an integrated regulatory network termed the endo-lysosomal-lipid axis. Disruption of this axis can impair endosomal maturation, lysosomal acidification, autophagic degradation, and lysosome-centered signaling pathways, resulting in defective cellular clearance and chronic inflammatory responses. Conversely, dysfunction of the endo-lysosomal system disrupts cholesterol trafficking, lipid redistribution, and macromolecular degradation, ultimately promoting secondary lipid accumulation and metabolic imbalance. In this review, we summarize the reciprocal interactions between lipid metabolism and endo-lysosomal function, with particular emphasis on membrane trafficking, lysosomal homeostasis, autophagy, membrane contact sites, and multicellular lipid clearance networks. We further discuss how these interconnected processes contribute to disease progression and highlight emerging therapeutic strategies aimed at restoring lysosomal function and lipid homeostasis.

These symptoms are heterogeneous and may reflect syndromal MDD, psychological and functional burden, fatigue, apathy, pseudobulbar affect, frontotemporal involvement, sleep or respiratory disturbance, medication effects, or shared affective vulnerability. A proposed pruning-continuum model suggests both disorders may share vulnerability in microglia-mediated synaptic pruning, with ALS amplified by autophagy and protein-quality-control failure and MDD by RNA-processing, stress, and immune dysregulation. We performed an exploratory secondary transcriptome-wide association study (TWAS)/pathway-integration analysis to test whether predefined nicotinamide mononucleotide (NMN)-nominated pathways map onto this vulnerability. We integrated precomputed S-PrediXcan outputs for MDD and ALS across available brain-relevant tissues. Ten Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were predefined from a prior re-analysis of NMN-associated transcriptional programs in aged mouse metabolic tissues. Mouse-derived candidates were represented by human ortholog symbols before the human TWAS screen. The analysis tested nominated pathways rather than the 35-gene NMN-robust list as a standalone set. Cross-tissue screening used Stouffer Z aggregation, tissue-level Wilcoxon testing, competitive permutation testing, percentile bootstrap intervals, pairwise disease statistics, Levene variance tests, concordance measures, and leave-one-out sensitivity analysis. No analysis was treated as confirmatory or evidence of causal mediation. MDD showed the strongest Stouffer-based exploratory signal in the synaptic vesicle cycle pathway, with a meta-across-tissue Stouffer Z of 3.41 and a wide bootstrap 95% confidence interval of -0.46 to 7.40. This signal did not survive competitive permutation testing (p = 0.1222) or Wilcoxon testing (p = 0.1926). The strongest tissue-level result occurred in the amygdala (Z = 4.057; nominal Wilcoxon p = 0.0093), although tissue-level permutation testing was not performed in the multi-gene-set run. ALS showed no significant meta-across-tissue enrichment among the 10 nominated pathways but displayed candidate gene-level signals in autophagy, endosomal, and vesicle-related genes, including TBK1 and C9orf72. Exploratory Levene tests indicated variance heterogeneity in the regulation of the actin cytoskeleton, endocytosis, and neuroactive ligand-receptor interaction; the actin cytoskeleton and endocytosis remained significant in pooled global false discovery rate (FDR) analysis. Fourteen genes were influential in at least two focus pathways, including EGF, KNG1, FGF8, RAC1, PAK1, PAK2, RAF1, MAPK1, and FGFR1. These findings are hypothesis-generating. MDD and ALS may stress overlapping cellular logistics processes while engaging largely different genes. MDD showed the strongest exploratory pathway-level signal in synaptic vesicle biology, whereas ALS showed candidate gene-level coherence in autophagy and endosomal processes without significant meta-pathway enrichment. NMN/NAD+ repletion is not established as a treatment for MDD, ALS, or their comorbidity. These findings generate hypotheses about NAD+-linked cellular stress pathways for future preclinical and clinical studies.",

Autophagy is essential for endothelial homeostasis, yet its role in aldosterone-mediated vascular dysfunction remains unclear. We tested whether aldosterone impairs autophagic flux and whether restoring autophagy via Beclin1 (BCN1) activation protects vascular and cardiac function. Endothelial and vascular responses to aldosterone were assessed in wild-type mice, BCN1 gain-of-function mice (Becn1), and mice treated with spermidine or a BCN1-activating TB-peptide. Vascular function, nitric oxide (NO)/reactive oxygen species (ROS) production, autophagy markers, endothelial migration, and cardiac fibrosis were evaluated using wire myography, fluorescence assays, Western blotting, confocal microscopy, migration assays, and histology. Aldosterone impaired endothelium-dependent relaxation, decreased NO, increased ROS, and disrupted autophagic flux in an MR-dependent manner, indicated by LC3 accumulation and reduced p62 and BCN1 expression. Spermidine restored endothelial function and normalized NO and ROS levels. BCN1 gain-of-function mice were protected from aldosterone-induced endothelial dysfunction and exhibited reduced coronary and myocardial fibrosis. TB-peptide activation of BCN1 enhanced autophagic flux, improved vascular function, decreased cardiac fibrosis, and rescued endothelial migration impaired by aldosterone. Aldosterone induces endothelial dysfunction by suppressing autophagic flux through MR activation. Genetic or pharmacologic enhancement of BCN1-dependent autophagy restores endothelial homeostasis and prevents vascular and cardiac injury, identifying autophagy activation as a promising therapeutic approach for cardiovascular diseases associated with mineralocorticoid excess.",

Emerging evidence implicates lipid dysregulation in neurodegeneration, but its extent across FTLD subtypes and how it compares to AD are unclear. Here, we performed integrated lipidomic and proteomic analyses of matched frontal (disease-vulnerable) and occipital (relatively spared) post-mortem cortices from individuals with genetic and sporadic FTLD-TDP, FTLD-tau (Pick's disease, PiD), AD, and controls. FTLD and AD exhibited convergent lipid alterations, including reduced levels of cardiolipins and phosphatidylethanolamines, alongside increased gangliosides, diacylglycerols, cholesterol esters, acylcarnitines, and coenzyme Q, with generally greater changes in FTLD frontal cortex. FTLD displayed additional alterations, including reductions in bis(monoacylglycerol)phosphate, ceramides, phosphatidylserines, phosphatidylinositols, and sulfatides. These lipid changes were accompanied by proteomic alterations involving lysosomal proteins, phospholipases, phospholipid remodeling enzymes, and fatty acid oxidation pathways. Although lipidomic and proteomic signatures were broadly shared across FTLD subtypes, GRN associated FTLD-TDP and PiD showed the most extensive alterations. Triglycerides were selectively reduced in PiD in association with decreased DGAT1 expression, whereas cholesterol esters were elevated across all subtypes except C9orf72 associated FTLD-TDP. These findings identify shared disruptions in lipid homeostasis and lysosomal lipid metabolism across FTLD and AD, highlighting convergent metabolic pathways underlying neurodegeneration.",

The polyamine spermidine was suggested to exert neuroprotective effects, but its concentration-dependent impact on longevity, neuronal integrity, and behavior remains still not well studied. Here, we investigated the effects of spermidine on lifespan, behavioral responses, brain tissue, target gene expression, and antioxidant status in Drosophila melanogaster model of age-dependent neurodegeneration. Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood. Lifespan analysis revealed that high-dose spermidine (5\u2009mM) reduced survival in both wild-type and sws1 mutants, whereas lower doses (0.5 and 1\u2009mM) significantly improved survival in mutants without affecting wild-type flies. Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations. Histological analysis of 10-13-day-old mutants showed a concentration-dependent reduction in degeneration zones within the lamina and medulla at 0.5 and 1\u2009mM, whereas 5\u2009mM had no effect. Biochemical assays indicated mild pro-oxidant effects at 5\u2009mM, reflected by increased malondialdehyde (MDA) levels, while 0.5\u2009mM enhanced antioxidant defenses, including catalase activity and Trolox equivalent antioxidant capacity (TEAC). Our results suggest that spermidine at low doses has the potential to be a general-purpose neuroprotector.",

Microglial dysfunction has been implicated in the pathogenesis of several neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and multiple sclerosis. Impaired lysosomal function, particularly defective lysosomal acidification, leads to the accumulation of undegraded material, thereby promoting neuroinflammation and neuronal damage. This review examines the mechanisms governing lysosomal acidification in microglia and evaluates its potential as both a therapeutic target and a prognostic biomarker in neurodegenerative diseases. The literature on microglial lysosomal acidification, lysosomal pH regulation, autophagy, and neurodegeneration was searched in PubMed, Scopus, and Web of Science. Relevant mechanistic, preclinical, and translational studies were critically appraised and synthesized. Lysosomal acidification is increasingly recognized as a key regulator of microglial function and homeostasis. Defective acidification, driven by dysregulation of the vacuolar H+-ATPase (V-ATPase) proton pump, TFEB/TFE3 signaling pathways, and lysosomal ion channels such as TRPML1 and TMEM175, impairs autophagic flux and substrate degradation, facilitating the accumulation of neurotoxic aggregates including amyloid-\u03b2 and \u03b1-synuclein. Emerging evidence suggests that the degree of microglial lysosomal acidification may serve as a prognostic biomarker for disease progression and therapeutic response. Restoration or enhancement of lysosomal acidification through pharmacological modulation of lysosomal pH, activation of autophagy, or targeting of key regulatory pathways has been shown to re-establish microglial homeostasis, attenuate neuroinflammation, and confer neuroprotection in preclinical models. Restoration of microglial lysosomal acidification represents a promising therapeutic strategy for neurodegenerative diseases. A deeper understanding of the molecular mechanisms regulating lysosomal acidification in microglia may facilitate the identification of novel biomarkers and therapeutic targets, ultimately contributing to the development of innovative interventions for neurodegenerative disorders.",

Limiting the damage caused by MIR is crucial but is still an unmet clinical need because of the complexity of the underlying mechanisms. Increasing evidence suggests that lysosomal autophagy plays a significant regulatory role in MIR injury. The specific mechanisms involved remain to be fully understood. We here systematically analyzed the murine MIR model database to screen the potentially protective lysosome-localized proteins against MIR injury. The positive hits were further functionally screened and validated for their capability on autophagy and hypoxia/reoxygenation insults of cardiomyocytes. After exploring the detailed molecular mechanism underlying the protective effects of the target protein, we generated target gene cardiac-specific knockout mice and overexpression mice to verify its function in mouse MIR injury models. LAPTM4A (lysosome-associated protein transmembrane 4 alpha) stood out as a significant protective lysosome-localized protein from the screening. LAPTM4A deficiency significantly heightened the inflammatory response and cell death both in primary cardiomyocytes and in a MIR-induced mouse model. Conversely, LAPTM4A overexpression exerted protective effects on cell viability and myocardial damage. Mechanistically, LAPTM4A interacts with Rubicon (Run domain Beclin1-interacting and cysteine-rich domain-containing protein), hindering its engagement within the Beclin1 complex, resulting in a robust augmentation of autophagic flux and thereby mitigating cardiac damage during reperfusion. It is important to note that Rubicon knockdown markedly reversed the aggravated injury induced by LAPTM4A knockdown, further verifying the effects of LAPTM4A depend on Rubicon. Our findings screened out and validated that LAPTM4A is a lysosome-localized protein exerting protective effects against MIR injury by facilitating autophagic flux. Targeting LAPTM4A represents a promising therapeutic strategy for mitigating MIR injury.",

Herein, we fabricated rapamycin-nanoliposomes (rapa-lipos) via ultrasonic dispersion, thin-film dispersion, and filtration to improve rapamycin bioavailability, investigating their role in inhibiting the senescence phenotype of NP cells through \u03b2-gal staining, lysosomal staining, transmission electron microscopy, ELISA, and cell cycle inhibitors. The mechanistic effects of rapa-lipos on mTORC1, NLRP3/Caspase-1 pathway (NCP) and autophagy-lysosomal pathway (ALP) were also analyzed by western blotting, immunofluorescence (IF), Si-RNA (raptor), and PCR. In vivo, rapa-lipos were injected into rat intervertebral disc with IL-1\u03b2-induced degeneration, assessed via HE staining, x-ray, MRI, and IF. Rapa-lipos exhibited high encapsulation efficiency, favorable drug loading, uniform particle size, and controlled release, suppressing NP cell senescence-related phenotypes (morphological changes, elevated IL-1\u03b2/TNF-\u03b1 secretion, increased \u03b2-gal activity, lysosomal dysfunction, upregulated P21/P16 and reduced P27 expression). Mechanistically, rapa-lipos targeted-inhibited mTORC1, then blocked NCP and activated ALP to maintain NP cell quiescence. In vivo, x-ray, MRI and histological evaluation confirmed rapa-lipos mitigated intervertebral disc degeneration. Collectively, rapa-lipos target mTORC1-mediated NCP and ALP to inhibit NP cell senescence, offering a promising strategy for intervertebral disc degeneration prevention.",
        "42553702": "ID: 42553702\nTitle: Distinct brain extracellular vesicle microRNA profiles differ in frontotemporal dementia and Alzheimer's disease.\nAbstract: Dementia is a syndrome caused by various diseases including Alzheimer's disease (AD) and frontotemporal dementia (FTD) with an estimated global prevalence of 60 million individuals. Recently, therapeutic development in the dementia field has accelerated, with the introduction of monoclonal antibody therapeutics such as Lecanemab and Donanemab. However, AD and FTD patients are still either diagnosed too late to benefit from available therapies or are misdiagnosed due to the clinical overlap between dementia subgroups making therapeutic intervention challenging. This highlights a real need to improve early diagnostic tools of neurodegenerative disease (ND) biomarkers. A potential source of such biomarkers come from small extracellular vesicles (sEVs), groups of cell-derived, lipid-bound assemblies with the capability to cross the blood-brain barrier (BBB) and known to carry pathogenic proteins associated with AD and FTD. A known cargo of sEVs is microRNA (miRNA), regulatory molecules that post-transcriptionally silence gene expression including transcripts of autophagic systems, processes which dysfunction in dementia-causing diseases leading to toxic aggregate build-up, causing neurodegeneration. The targeting of functional machineries in macroautophagy (MA) and chaperone-mediated autophagy (CMA) by different miRNA may vary between AD and FTD mutations, leading to potential biomarkers of disease being highlighted. Through isolating sEVs from the frontal cortex of post-mortem brain tissue of AD, FTD-MAPT, FTD-C9orf72, FTD-GRN and no-disease control patients (Manchester Brain Bank), miRNA cargoes were analysed and compared using real-time quantitative PCR (RT-qPCR). Seven autophagy-associated miRNA candidates (MA: miR-124-3p, miR-30a-5p, miR-128-3p; and CMA: miR-224-5p, miR-373-5p, miR-106a-3p and miR-26b-5p) were tested to identify dementia sub-group variations, used alongside small RNA-sequencing to explore broader miRNA variation within sEV populations. Of the miRNA tested miR-224-5p (P = 1.76 \u00d7 10-5) and miR-106a-3p (P = 0.033) showed significant group differences, and further significant pairwise comparison differences [miR-224-5p: AD fold change (FC) = 4.29, MAPT FC = 7.62; miR-106a-5p: AD FC = 5.59] when compared with no disease controls and other dementia subgroups, potentially showing initial diagnostic and differentiating potential. Small RNA-sequencing results revealed 8 AD, 2 FTD-GRN, 52 FTD-MAPT and 12 FTD-C9orf72 differentially expressed sEV-miRNAs when compared with no disease controls. Further direct comparisons between AD versus FTD mutation-derived sEV cargoes, and even FTD mutation versus FTD mutation-derived sEV cargoes, identified additional miRNA with differentiating capabilities. These findings demonstrate sEV-derived miRNA signatures vary across dementia sub-types and suggest potential roles of sEV cargoes in both disease diagnostics and identifying drivers of ND, such as autophagic impairments and signalling pathways.",
        "42555669": "ID: 42555669\nTitle: Glial cell toxicity in a Drosophila C9orf72 neurodegeneration model.\nAbstract: The most common genetic cause of both familial amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) is an expanded G4C2 repeat in the first intron of the gene C9orf72. The C9orf72 repeat expansion is bidirectionally transcribed into sense and anti-sense RNA foci, and also produces dipeptide repeats (DPRs) via a non-canonical translation mechanism known as repeat-associated (RAN) translation. Each of these components of the G4C2 repeat expansion cause neurodegenerative effects in animal models when expressed in neurons, but impacts from glial expression are more poorly understood. Here, we use glial cell type-specific expression of individual DPRs, of RNA repeat-only, or of the G4C2 repeat, that produces both DPRs and RNA repeats, to systematically investigate glial toxicity of each component. We find that as with neurons, the GR and G4C2 transgenes produce the highest degree of toxicity when expressed in glia. Each of these transgenes are capable to produce the GR DPR, which also is the most toxic factor in neurons. We demonstrate that both the GR and G4C2 transgenes cause activation of mdg4, an endogenous retrovirus (ERV). Such ERV expression is a hallmark of TDP-43 dysfunction that is commonly observed in C9orf72 patients. We find that glial expression of either the GR or the G4C2 transgene is toxic to glial cells, but such expression does not cause loss nearby neurons. However, blocking apoptotic signaling within glia that express either GR or G4C2 via expression of the p35 caspase inhibitor further exacerbates effects on lifespan and ablating such glia via expression of the proapoptotic reaper gene partially ameliorates these effects. Together, these results indicate that expression of toxic C9orf72 components in glia produces deleterious effects on lifespan, though potentially through different mechanisms than seen in TDP-43 models of ALS/FTD.",
        "42555719": "ID: 42555719\nTitle: Renoprotective effects of tubular glucagon receptor activation mediated by V-ATPase.\nAbstract: Recent clinical trials have shown that dual GLP-1R/GCGR agonists, including mazdutide and cotadutide, provide kidney benefits in patients with type 2 diabetes and CKD, suggesting a potential contribution of GCGR activation to these renal effects. However, whether GCGR directly confers renoprotection and the underlying mechanisms remain unclear. Here, using tubule-specific GCGR loss- and gain-of-function mouse models and human kidney samples, we show that tubular GCGR signaling exerts an important renoprotective role in DKD. Tubular GCGR expression is reduced in humans and mice with DKD and correlates with worse kidney function and increased renal injury. Genetic ablation of tubular GCGR markedly exacerbates DKD and induces pronounced phospholipid accumulation within enlarged lysosomes. Mechanistically, GCGR loss disrupts its association with the V-ATPase V1A subunit ATP6V1A, compromises V1-V0 assembly, and thereby impairs lysosomal acidification. This defect leads to impaired phospholipid hydrolysis and protease maturation, blockade of autophagic flux, and ultimately tubular cell injury. In vivo, ATP6V1A overexpression markedly reverses GCGR deficiency-induced lysosomal dysfunction and DKD progression. Consistently, re-expression of tubular GCGR via AAV9 restores lysosomal function, reduces phospholipid accumulation, and mitigates renal injury in DKD. Together, these findings provide genetic evidence for the renoprotective role of tubular GCGR in DKD, delineate a kidney-intrinsic GCGR-ATP6V1A-lysosome axis that protects tubular integrity, and extend prior GCGR-in-kidney observations into a more concrete GCGR-lysosome mechanism.",

However, approximately half of the FTD patients are sporadic without a clear genetic background. To compare characteristics of microglia from different FTD subtypes, we generated induced pluripotent stem cell-derived microglia (iMG) from sporadic and C9-HRE-carrying behavioral variant FTD (bvFTD) patients and healthy controls. C9-HRE iMG displayed C9-HRE-associated RNA foci and dipeptide repeat proteins. All bvFTD iMG had fewer LAMP2-A-positive vesicles compared to control iMG. Additionally, C9-HRE iMG showed significantly increased LC3BII/I conversion after bafilomycin A1 treatment and altered phagocytic activity. The gene expression profile of C9-HRE iMG only modestly differed from the control iMG, but was greatly different from the sporadic bvFTD patient iMG. Our data show alterations in phagocytic and autophagosomal/lysosomal pathways and gene expression profiles between C9-HRE and sporadic bvFTD iMG for the first time.",

Human lysosomal storage disorders provide compelling evidence that isolated lysosomal defects are sufficient to cause early cardiomyopathy, underscoring the myocardium's exceptional dependence on sustained lysosomal competence. In physiological aging, impaired autophagy is the most apparent manifestation of lysosomal decline but represents only one facet of a broader network regulating nutrient sensing, ion and lipid homeostasis, receptor trafficking, exocytosis/secretion and inter-organelle communication. Here, we review established and emerging lysosome-dependent mechanisms across the hallmarks of cardiac aging, highlighting lysosomes as potential upstream drivers of this process. We discuss key knowledge gaps and therapeutic strategies aimed at restoring lysosomal function, positioning lysosomes as central and actionable targets for preserving cardiac resilience with age.",

Recent advances have highlighted the critical role of the interplay between \u03b1-Syn and lysosomal function, termed the \u03b1-Syn-lysosome axis, as a central mechanism underlying PD pathogenesis. This review systematically summarizes the molecular mechanisms driving \u03b1-Syn aggregation and the lysosomal dysfunction contributing to impaired autophagy-lysosome pathway (ALP) activity. We further discuss emerging therapeutic strategies targeting this axis to restore lysosomal function and mitigate \u03b1-Syn toxicity.

This review summarizes recent advances in understanding how HDL function is affected by its associated proteins, demonstrating that this is a more appropriate lens through which to assess HDL's protective capacity. Recent publications have demonstrated an inverse relationship between ApoM and clinical outcomes in chronic kidney disease and its concomitant cardiovascular indications. Mechanistic studies show that ApoM's regulation of mitochondrial function and autophagy are likely contributors to this effect. Additionally, ApoA-I, serum amyloid albumin (SAA), and SR-B1 have recently been highlighted as key regulators of atherogenesis through their ability to prevent LDL transcytosis and arterial entrapment by proteoglycans. Lastly, a novel mechanism is described wherein HDL-bound endotoxin is degraded through the endosome-lysosome pathway in an SR-B1-dependent manner, attenuating IL-1\u03b2 activation. In the same study, inhibition of CETP (cholesterol ester transfer protein) increased HDL and improved mortality in a mouse model of sepsis, highlighting this pathway's importance and therapeutic potential of CETP inhibition, which is currently in key clinical trials.

Tripartite Motif 16 (TRIM16), an E3 ubiquitin ligase, is implicated in cellular stress responses, but its role in SIC remains unknown. In neonatal rat cardiomyocytes (NRCMs) and a murine cecal ligation and puncture (CLP)-induced sepsis model, we manipulated TRIM16 expression using small interfering RNA (siRNA), plasmids, or adeno-associated virus (AAV9)-mediated gene delivery. Cardiac function, injury markers, oxidative stress, inflammation, apoptosis, calcium handling, lysosomal function, and autophagy were assessed. Mechanistic studies focused on caveolin-1 (Cav-1) ubiquitination, non-receptor tyrosine kinase (Src)/yes-associated protein (YAP) activation, and the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway. TRIM16 expression was markedly upregulated in cardiomyocytes under septic conditions. Knockdown of TRIM16 exacerbated lipopolysaccharide (LPS)-induced cardiomyocyte injury, amplifying oxidative stress, inflammation, apoptosis, calcium dysregulation, lysosomal dysfunction, and impaired autophagy. In contrast, TRIM16 overexpression significantly attenuated cardiac dysfunction and injury in CLP-challenged mice. Mechanistically, TRIM16 directly promoted ubiquitination and degradation of Cav-1, which relieved Cav-1-mediated inhibition of Src kinase (increased p-Src Y416 and decreased p-Src Y527). This led to YAP phosphorylation at Y357, nuclear translocation, and subsequent activation of the Nrf2/HO-1 antioxidant pathway, thereby mitigating oxidative stress and restoring redox homeostasis. This study identifies a previously unrecognized protective role for TRIM16 in SIC via the novel Cav-1/Src/YAP/Nrf2 signaling axis. By enhancing TRIM16 activity, oxidative stress and cardiac dysfunction are mitigated, positioning TRIM16 as a promising therapeutic target for SIC.",

This study investigated the effects of cholesterol overload on human Ether-\u00e0-go-go-Related Gene (hERG/Kv11.1; encoded by KCNH2) potassium channels and L-type calcium channels (LTCC; mainly Cav1.2/CACNA1C in cardiomyocytes), as well as the underlying mechanisms of acLQTS-related cardiotoxicity, using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), whole-cell patch clamp, quantitative real-time PCR (qRT-PCR), Western blotting, immunoprecipitation, fluorescence imaging, and a high-cholesterol diet guinea pig model with rosuvastatin intervention combined with optical mapping. The results showed that transient cholesterol exposure inhibited hERG tail current amplitude and accelerated channel inactivation, with the effect showing a Y652-dependent component, while also enhancing LTCC activity. Mechanistically, cholesterol overload triggered endoplasmic reticulum (ER) stress, impaired hERG proteostasis, and promoted ER-to-lysosome-associated degradation (ERLAD) of hERG. This process was associated with CANX-mediated recognition of abnormal hERG and FAM134B-LC3B-related autophagic-lysosomal processing, contributing to reduced total hERG expression and membrane-localized mature hERG. FAM134B overexpression partially preserved hERG expression and attenuated cholesterol-induced ER stress/autophagy-related abnormalities. In vivo, rosuvastatin improved lipid profiles and cardiac remodeling in high-cholesterol guinea pigs but was associated with more pronounced action potential duration (APD) and QT interval prolongation under high-cholesterol conditions. These findings suggest that cholesterol overload may increase susceptibility to hERG-related repolarization abnormalities during rosuvastatin exposure and highlight the importance of cholesterol management and electrocardiographic (ECG) monitoring in hypercholesterolemic settings.",

An emerging transcriptomic process that is also increasingly implicated in brain aging, neuroinflammation, and disease is the dysregulation of transposable elements (TEs), repetitive genomic sequences with the potential to cause cellular stress/dysfunction. However, there are limited data on microglial TE transcript patterns in these contexts. Here, we analyzed multiple RNA-seq datasets from isolated human and mouse microglia across aging, Alzheimer's disease (AD), and AD-associated pathology. In contrast to previous observations based on whole-brain tissue and other brain cell types, we found that microglial TE transcript levels remained relatively consistent throughout most of the human lifespan before increasing in late life. We also found that TE transcript levels in microglia from AD patients showed minimal changes compared to age-matched controls, and in RNA-seq analyses of transgenic AD mouse models we observed pathology-associated TE transcript decreases. Subsequent analyses identified inverse associations between TE transcript levels and autophagy/lysosome-related gene expression, and in\u00a0vitro studies suggested that aging- and AD-relevant stimuli, as well as pharmacological autophagy inhibition, modulate TE transcript expression in cultured human microglia. Together, these data provide novel insight into TE transcript dynamics in microglia, highlighting TE transcript patterns that differ from those observed in whole-brain samples and other cell types in aging and AD.",

This narrative review examines four mechanistically distinct compounds, namely spermidine, fisetin, berberine, and urolithin A, as emerging functional food ingredients with scientifically supported effects on key hallmarks of human aging. Spermidine, a dietary polyamine from wheat germ and fermented foods, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Fisetin, a flavonoid from strawberries and apples, exerts senolytic activity by selectively eliminating senescent cells via PI3K/AKT and Bcl-2/Bcl-xL inhibition, with emerging clinical evidence. Berberine, an isoquinoline alkaloid from Berberis species, modulates metabolic dysfunction via AMP-activated protein kinase (AMPK) activation and reshapes gut microbiota composition through direct high intraluminal exposure, with the most extensive clinical dataset of the four compounds. Urolithin A, a gut microbiome-derived postbiotic from ellagitannins in pomegranates and nuts, induces mitophagy via PINK1/Parkin and has been evaluated in a growing number of registered human clinical trials. Together, the four compounds primarily target distinct but complementary aging-associated pathways (autophagy, senolysis, metabolic regulation, mitophagy), suggesting rational potential for combined functional food formulations.

We reanalysed the Genetic and Epigenetic Signatures of Translational Ageing Laboratory Testing(GESTALT) paired RNA sequencing (RNA-seq) and tandem mass tag (TMT) proteome from 82 donors (aged 22-89) using Data Integration Analysis for Biomarker discovery using Latent cOmponents (DIABLO) for supervised multi-omics integration, weighted gene co-expression network analysis (WGCNA), external Genotype-Tissue Expression(GTEx) transcriptomic comparison, network medicine proximity mapping and CDOCKER molecular docking. Three analyses converged on the autophagy-lysosome axis: Kyoto Encyclopaedia of Genes and Genomes (KEGG) Lysosome ranked first in discordant-quadrant analysis; gene set enrichment analysis (GSEA) identified vacuole organisation and macroautophagy as the top age-upregulated Gene Ontology (GO) terms; and WGCNA recovered KEGG Lysosome in the brown module. Module regression localised most proteomic age signals to the lysosomal degradative-capacity module, whereas the proteasome was unaffected. McNemar testing and GTEx comparison supported a protein-side, post-transcriptional origin. TCIRG1, CTSA and ATP6V0D1 were recurrent hubs. Network proximity computationally prioritised hydroxytyrosol as a lysosomal-degradative-capacity-preferential candidate, and CDOCKER on cathepsin A linked its advantage over tyrosol to an ortho-hydroxyl group forming additional hydrogen bonds. These results support protein-layer-dominant autophagy-lysosome remodelling as a feature of dermal fibroblast ageing and suggest a cell-type-resolved computational route from ageing proteomics to testable dietary candidates.",

However, the molecular mechanisms regulating GSDMD pore formation in these cells remain unclear. Given the established role of the lysosomal acid sphingomyelinase (ASM)-ceramide pathway in obesity-related glomerulopathy (ORG), we investigated whether ASM regulates obesity-induced GSDMD pore formation and pyroptosis in podocytes, thereby influencing the progression of ORG. We found that podocyte-specific Smpd1 (the gene encoding ASM) overexpression markedly enhanced high-fat diet (HFD)-induced NLRP3 inflammasome activation, GSDMD N-terminal fragment (GSDMD-NT) generation, and pyroptosis in glomeruli of Smpd1trg/Podocre mice compared to wild-type controls. Pharmacological inhibition of ASM or the NLRP3 inflammasome attenuated these pathological changes in obese mice. In contrast, inhibition of GSDMD pore formation with disulfiram (DIS) prevented HFD-induced pyroptosis without affecting NLRP3 inflammasome activation. Consistently, obesity-induced podocyte injury and glomerulosclerosis were exacerbated by ASM overexpression but alleviated by inhibition of ASM, the NLRP3 inflammasome, or GSDMD pore formation. Using primary podocytes isolated from wild-type, Smpd1 knockout (Smpd1-/-), and Smpd1trg/Podocre mice, we further demonstrated that palmitic acid (PA), an obesity-associated lipotoxic factor, induced NLRP3 inflammasome activation, GSDMD pore formation, inflammasome product release, and pyroptosis. These responses were suppressed by Smpd1 deletion but enhanced by ASM overexpression. Confocal and super-resolution microscopy revealed that PA increased the accumulation of autophagosomes containing GSDMD-NT while impairing lysosome-autophagosome fusion, effects that were mitigated by Smpd1 deletion and amplified by ASM overexpression. To further elucidate the underlying mechanism, we examined whether ASM regulates lysosomal TRPML1 channel-mediated Ca2+ release, thereby controlling lysosome-autophagosome interaction and GSDMD-NT degradation. PA inhibited TRPML1 channel activity in podocytes, an effect that was intensified by ASM overexpression. Furthermore, PA-induced impairment of lysosome-autophagosome interaction and increased GSDMD pore formation were attenuated by the TRPML1 agonist ML-SA5 and exacerbated by the TRPML1 inhibitor ML-SI1. Collectively, these findings indicate that ASM regulates lysosomal function and autophagic degradation of GSDMD-NT, thereby controlling GSDMD pore formation and pyroptosis in podocytes during ORG.",

Modulation of TDP-43 pathology represents a promising disease-modifying strategy. Tau tubulin kinase 1 (TTBK1) has emerged as a relevant therapeutic target; however, selectivity over the TTBK2 isoform is required to avoid ciliogenesis-related liabilities. Here, we report the discovery of selective, brain-penetrant TTBK1 inhibitors through a structure-guided medicinal chemistry program. Lead compounds exhibit potent and selective TTBK1 inhibition, no impact on ciliogenesis, and central nervous system exposure. We found that these inhibitors reduce TDP-43 phosphorylation levels in neuroblastoma cells and FTD patient-derived models. The optimized lead compound demonstrated a brain-to-plasma ratio of 3:1, a maximum tolerated dose, and a wide therapeutic window. In vivo, administration restored cognitive deficits, conferred neuroprotection in the frontal cortex, and reduced microglial activation in an FTD-TDP mouse model, supporting its therapeutic potential.",
        "42594853": "ID: 42594853\nTitle: Beyond the ATP-binding pocket: emerging strategies in kinase targeting from allosteric inhibition to targeted protein degradation.\nAbstract: Protein kinases are central regulators of cellular signaling and remain a major target class in precision medicine. While ATP-competitive inhibitors-including conformation-selective and covalent agents-have delivered substantial clinical benefit, durable responses are frequently limited by the conservation of the ATP pocket and the emergence of resistance mutations (e.g. gatekeeper and solvent-front substitutions), as well as kinase noncatalytic functions that are not addressed by enzymatic inhibition alone. Consequently, kinase drug discovery is expanding beyond orthosteric occupancy toward modalities that reprogram kinase conformations or eliminate the target protein. This Review summarizes the structural and medicinal chemistry principles underlying (i) allosteric inhibition and (ii) proximity-induced degradation, with an emphasis on design logic, structure-activity relationships, and key liabilities in the beyond rule of five space. We further highlight enabling technologies-including structural biology, chemical proteomics, and AI/ML-assisted modeling-that support allosteric site identification, ternary complex engineering, and multi-parameter optimization. Finally, we discuss translational challenges for bifunctional molecules, including permeability, exposure-response relationships, off-target degradation, and safety, and propose practical considerations for developing next-generation selective kinase therapeutics.",
        "42596071": "ID: 42596071\nTitle: An expanding role for ATG8s and ATG8 E3-like ligases in maintaining membrane integrity.\nAbstract: Endolysosomal membranes are frequently damaged by pathogenic stress associated with aging, infection, and neurodegeneration, and failure to repair such damage leads to inflammation and cell death. Recent advances identify membrane ATG8 conjugation (atg8ylation) as a key process that links damage detection to coordinated lysosomal repair, removal, and regeneration. Beyond its canonical role in macroautophagy, membrane atg8ylation also occurs on preexisting, non-autophagosomal single membranes through Conjugation of ATG8s to Single Membranes (CASM), positioning this pathway as a rapid response to membrane stress. Two E3-like ligase complexes, ATG16L1-ATG5-ATG12 and TECPR1-ATG5-ATG12, act as complementary sensors of lysosomal injury by detecting distinct physicochemical cues, including proton gradient collapse and lipid scrambling. These ligases convert damage signals into spatially restricted membrane atg8ylation, generating a membrane-associated platform that coordinates multiple downstream pathways. These include ESCRT-dependent membrane repair, ER-lysosome lipid transfer, membrane tubulation, and stress granule formation. When repair fails, membrane atg8ylation regulates lysophagy and activates lysosomal biogenesis and regeneration to restore lysosomal homeostasis. These emerging findings define membrane atg8ylation as a central organizer of membrane quality control rather than a pathway merely confined to macroautophagy. In this review, we summarize the current understanding of how membrane atg8ylation detects lysosomal damage and how this pathway coordinates other lysosomal quality control mechanisms to maintain lysosomal integrity.",

Although autophagy dysregulation is implicated in MM pathogenesis, its precise regulation, particularly by circular RNAs (circRNAs), is poorly understood. Through clinical RNA sequencing of primary MM patient samples, we identify an autophagy-associated circRNA, circ_0008255, which is markedly upregulated in MM patients and closely correlated with poor disease prognosis. Functional studies reveal that circ_0008255 promotes MM proliferation and tumor growth by enhancing autophagic activity. Mechanistically, it functions as a competitive endogenous RNA for miR-192-5p, leading to elevated expression of the core autophagy protein, autophagy related 2 homolog A (ATG2A). Furthermore, we developed a biomimetic nanoplatform based on layered double hydroxide (LDH) nanosheets coated with myeloma-derived cell membranes for tumor-specific delivery. This system co-delivers siRNA targeting circ_0008255 to suppress autophagosome initiation, while simultaneously leveraging the lysosome-alkalinizing property of LDH to impair autophagosome-lysosome fusion. Together, these actions enforce a synergistic autophagic full-chain blockade, leading to potent antitumor effects in vitro and in vivo. Overall, our study reveals a central regulatory role of circ_0008255 in myeloma autophagy, offering a promising therapeutic paradigm for MM.",
        "42598912": "ID: 42598912\nTitle: A live-cell autophagy reporter reveals reversible vacuolation in naked mole-rat skin fibroblasts under lysosomal stress.\nAbstract: Naked mole-rats (NMRs, Heterocephalus glaber) display unusual longevity and resistance to age-related decline, and accumulating evidence suggests that their autophagy-lysosome pathway (ALP) is regulated differently from that of conventional mammalian models. However, most studies in NMR cells have relied on static biochemical or ultrastructural readouts, leaving the dynamic organisation of autophagy in living cells poorly defined. Here, we establish a stable tandem fluorescent autophagy reporter in NMR skin fibroblasts using an mCherry-EGFP-LC3NMR construct to enable live-cell, single-cell resolution analysis of ALP dynamics. Under basal conditions, NMR skin fibroblasts exhibit a greater abundance of LC3-positive structures than HeLa cells, together with a mixed population of autophagosomes and autolysosomes, indicating a distinct steady-state organisation of the ALP. Chloroquine (CQ)-induced lysosomal stress caused the expected accumulation of LC3-positive structures but also triggered the formation of large cytoplasmic vacuoles in NMR skin fibroblasts. Importantly, this vacuolation was not associated with acute cytotoxicity and progressively resolved following CQ removal, accompanied by reorganisation of LC3-positive compartments and recovery of lysosomal acidity. Electron microscopy showed that CQ-induced vacuoles are membrane-bound, containing internal material and co-existing with multiple ALP-related vesicular compartments. Primary NMR skin fibroblasts display a similar vacuolation phenotype, indicating that this response is not an artefact of immortalisation or reporter expression. Together, these findings establish a live-cell platform for analysing autophagy in NMR cells and identify a distinctive, reversible vacuolation response to lysosomal stress, consistent with dynamic remodelling of the lysosomal system within NMR skin fibroblasts.",
        "42599231": "ID: 42599231\nTitle: [Yeast as a Biochemical Model for Diseases Associated with Impaired Intracellular Proteolytic Systems].\nAbstract: The degradation of intracellular proteins is a fundamental biological process necessary for maintaining cellular homeostasis, controlling the cell cycle, regulating signal transduction, and preventing the accumulation of toxic protein aggregates. Disorders of the proteolytic systems are implicated in the pathogenesis of numerous human diseases, including neurodegenerative diseases, lysosomal storage disorders, metabolic disorders, and certain types of cancer. The development of rudimentary and cost-effective models of these diseases for the purpose of evaluating novel pharmaceutical agents and elucidating the molecular mechanisms underlying disease pathogenesis constitutes a pivotal medical and biological undertaking. The proteolytic apparatus of the yeast species Saccharomyces cerevisiae has become a biochemical model organism of significant importance. This is due to its well-studied nature, low cost, ease of genetic manipulation, and evolutionary conservatism. The mechanisms of proteolytic system dysfunction can be studied in this organism. Furthermore, therapeutic approaches aimed at correcting these dysfunctional mechanisms can be sought.",
        "42605115": "ID: 42605115\nTitle: Surface-Engineered Carbon Dots for Monitoring of Lysosomal Viscosity and Organelle Dysfunction.\nAbstract: The development of robust, photostable nanoprobes for precise organelle targeting remains a cornerstone in chemosensing and advanced bioimaging. Alterations in the lysosomal microenvironment serve as an indicator of organelle health and disease progression. Herein, a sustainable synthetic strategy is presented for benzothiazole-modified carbon dots (LysoDots), engineered for specific lysosome localization and viscosity monitoring. LysoDots display a viscosity-dependent fluorescence enhancement in glycerol-water systems while remaining insensitive to physiological pH and temperature variations. This turn-on response allows for the high-fidelity tracking of lysosomal microviscosity changes induced by exogenous stimuli, such as nystatin, and endogenous processes like rapamycin-induced autophagy. Confocal imaging demonstrates a remarkable colocalization of LysoDots with the commercial lysosome marker, LysoTracker Green (LTG), showing a Pearson's correlation coefficient of 0.92 in CAL-33 oral carcinoma cells, with the red emission effectively differentiating lysosomal viscosity profiles between cancerous and non-cancerous cells. Furthermore, the LysoDots were successfully employed in a neuronal model, SH-SY5Y cells, where the probe effectively tracked glutamate-induced lysosomal dysfunction, mimicking the pathology of lysosomal storage disorders, along with the viscosity restoration mediated by trehalose. These findings highlight the potential of LysoDots as a biocompatible, photostable, multi-functional nanomaterial for long-term monitoring of lysosomal dynamics and cellular homeostasis.",
        "42607684": "ID: 42607684\nTitle: ER-liquid condensate contacts sequester FAM134B/C and RhoA to govern cell morphology.\nAbstract: Endoplasmic reticulum (ER)-phagy receptors have elusive physiological functions beyond ER remodeling. To gain insight into these, we screen for cytoplasmic interactors of well-known receptors in mouse pancreatic ductal adenocarcinoma cells. Our data subsequently reveal a non-canonical action of PRKAR1A, a subunit of protein kinase A (PKA), in binding and activating FAM134B/C. At a molecular level, an amphipathic helix in the otherwise-disordered C terminus of FAM134B directly binds PRKAR1A dimers. Multimodal imaging reveals that this interaction occurs at interorganellar contact sites between the ER and liquid-like condensates of PRKAR1A. Mechanistically, ER-condensate contacts promote clustering of FAM134B/C with LC3B and recruit lysosomes, forming degradation hubs. Unexpectedly, these structures are found to control cytoplasmic signaling through FAM134B/C-mediated lysosomal sequestration of RhoA. Underscoring the physiologic relevance of this, these cytoplasmic-facing actions of FAM134B/C result in RhoA-dependent cell morphologic and migratory control in response to cyclic AMP (cAMP) stimuli. Thus, interorganellar contacts expand the roles of FAM134B/C ER-phagy receptors beyond ER degradation."
